Dining table with integral dishwasher

[0002] This invention relates to a combination dining table-dishwasher apparatus, and more particularly to improvements to the type of dining table-dishwasher apparatus shown in Applicant's prior U.S. Pat. No. 6,378,537 entitled “Dining Table With Integral Dishwasher” issued Apr. 30, 2002.

[0003] Most contemporary homes have an automatic dishwasher that is installed beneath a counter surface in the home's kitchen in place of a storage cabinet. With such a dishwasher arrangement, dishes must be removed from the eating table and carried to the dishwasher to be washed. Frequently, similar types of dishes, e.g. dinner plate, salad bowl, etc., are used for many meals. After the dishes are washed, and before a subsequent meal is eaten, the dishes must be moved again to the table. In this arrangement, not only does the dishwasher occupy kitchen space that could otherwise be used for storage but also one must move the dishes back and forth between the counter and the table.

[0004] In some homes, a dishwasher is portable, that is, not installed at all, but moveable about the kitchen floor. A portable dishwasher solves the storage space drawback of the built-in dishwasher noted above, but it occupies extra and much desired additional floor space. If the portable dishwasher is located near the kitchen sink, it again requires transporting the dishes to and from the table for washing. If the portable dishwasher is located near the table, then a power cord, a water line, and a waste line need to traverse from a wall source across the kitchen floor, which acts to further reduce desired kitchen space.

[0005] It is also known to position a dishwasher beneath the dining surface of a table in the kitchen, thus overcoming all the obstacles of the conventional built-in as well as portable dishwashers as discussed above. The typical dining table covers an open area of unused space. The dining table is, by definition, the venue for eating. Placing a dishwasher device under a dining table avoids the need to transport the dishes to and from the table, allows more space beneath the kitchen counter for storage, and does not require electric and water lines to traverse the kitchen floor, since they can be routed directly from below the table.

[0006] In addition to the benefits derived from a dishwasher that is built into a dining table as noted above, such an arrangement is of particular benefit to physically handicapped and elderly persons who have more than average difficulty with the task of moving dishes between a table and a dishwasher.

[0007] A washing apparatus built into a dining table is disclosed in U.S. Pat. No. 1,952,568 to Schapp et al., issued Mar. 27, 1934, for a “Convertible Dishwashing Dinner Table”. The Schapp et al. disclosure includes a series of eating trays that mount into the surface of the table. The trays may be formed with cavities to receive food. The user attaches utensils and dishes to clips on the trays and inverts the tray so that its eating surface faces down for being washed. The non-eating surface does not get washed.

[0008] A further washing apparatus in a dining table is taught in U.S. Pat. No. 2,782,426 to Townsend, issued Feb. 16, 1957, for a “Table Having Reversible Tray Mounted Therein And Means For Washing The Same”. The Townsend table incorporates trays into its top surface. The trays are moveable from an eating position to a washing position by rotating around a mounting shaft. Again, only the eating surface is subject to being washed.

[0009] An additional combination dining table and dishwashing apparatus is shown in U.S. Pat. No. 2,971,519 to Willson, issued Feb. 14, 1961, entitled “Combined Dining Table And Dishwasher”. The apparatus of Willson provides a dish and utensil compartment within a storage base of the table. A dishwashing unit operates to wash the dishes that are placed on holders in the compartment. The Willson patent does not incorporate a tray component.

[0010] A still further combination dishwasher and dining table is disclosed in U.S. Pat. No. 5,687,752 to Boylan, issued Nov. 18, 1997, entitled “Dining Table Having Integral Dishwasher”. The device of the Boylan patent has a washing basin with a vertically shiftable rack assembly for carrying dishes. A shifting mechanism is coupled with the rack assembly for shifting the rack between a position below the tabletop to a position above the tabletop. A lid is carried up and down with the rack by the shifting mechanism. However, the apparatus described in the Boylan patent appears to open up the undesired possibility of discharging water onto the tabletop if opened at the wrong time and also lacks a necessary eating tray.

[0011] The combination dining table-dishwasher apparatus of the type described in Applicant's prior U.S. Pat. No. 6,378,537, issued Apr. 30, 2002 entitled “Dining Table With Integral Dishwasher”, has brought about numerous improvements over the prior art described above. The combination dining table suitable for use by either one or two persons and with an integral dishwasher apparatus for each as illustrated in the '537 patent incorporates hinged-together pairs of inner and outer access covers over a dishwasher. In a first position, each pair of access covers are stored one above the other and an eating tray used for dining is loosely mounted above the stored access covers. In a second position, the hinged-together pair of inner and outer access covers are positioned over the dishwasher in a coplanar relation and form a surface, which in lieu of using the dining tray can be used for dining or as a work surface in the mentioned first position.

[0012] With the above as background, Applicant has discovered, through use of the '537 patent apparatus, a need to improve: a) the smoothness of the dining/work surfaces established by the inner and outer access covers when in place over the dishwasher apparatus; b) the mechanism used to support and position the inner and outer access cover; and c) the ease of operation of such mechanism.

[0013] Thus, the principal object of the present invention as distinct from the prior invention described in the '537 patent is to provide a relatively smooth dining/work surface when its access covers are in a closed position so as to provide a more easily cleaned dining/work surface and therefore a more sanitary surface when the inner and outer access covers are in a closed position over the dishwasher apparatus.

[0014] Another object of the present invention, is to provide a dining table with an integral dishwasher that is easy to open, close and operate by those with physical problems, e.g. arthritis of the hands and/or fingers.

[0015] Objects of the prior invention as recited in Applicant's prior '537 patent also become objects of the present invention.

[0016] It is an additional object of the present invention to provide a dining table with an integral dishwasher that is more aesthetically pleasing.

[0017] Yet another object of the present invention is to provide a dining table with an integral dishwasher that is very economical to manufacture.

[0018] The foregoing and other objects of the present invention will become more apparent through the disclosure of the invention to follow.

[0019] The present invention incorporates many of the desirable features of the combination dining table-dishwasher apparatus described in applicant's previously issued U.S. Pat. No. 6,378,537. The present invention provides a dining table, whose inner and outer access covers can be positioned so as to establish a top surface that is substantially free of any obstructions and is most useful as a food preparation surface as well as a surface upon which to eat. The invention apparatus incorporates at each dining location a pair of two-piece, inner and outer access cover structures, which are easily openable and when open give access to an eating tray and eating utensils and dishes stored within the combined dining table and integral dishwasher cabinet structure. Each inner and outer access cover operates independent of the other through a novel hinge arrangement for the inner access cover and a novel release locking arrangement and mechanism for the outer access cover. The release mechanism allows the outer one of each pair of access cover members to move from an uppermost position to a lowermost position. When the outer access cover reaches this lowermost position it causes the other inner access cover member to be tilted upward slightly. The user can then easily grasp the tilted inner cover member and move it into its open position at which time the locking mechanism maintains both cover members in an open position and allows an eating tray to be withdrawn from within the dishwasher cabinet structure. After eating, the dishes and utensils are placed within a dishwashing chute within the integral dishwasher cabinet structure, the eating tray is moved back into the dishwashing apparatus, and the locking mechanism is released, which allows each of the access cover members to move from its respective open position to its respective closed position and so as to permit the dishwasher mechanism to be activated for washing the tray, dishes and utensils stored therein.

[0020] In order for the invention to become more clearly understood it will be disclosed in greater detail with reference to the accompanying drawings, in which:

[0035] FIG. 15 is a partial, cut-away bottom view of a pair of oppositely-positioned spring-loaded spray barriers that releasably engage the edges of the eating tray and are forced to spread apart to the full width of the eating tray when it is being withdrawn and after the tray has been withdrawn are each forced inwardly under spring pressure so as to provide a spray barrier at each of the inner side portions of the opening in which the eating tray resides when being used.

[0036] The description is first directed primarily to the subject matter of Applicant's prior U.S. Pat. No. 6,378,537 and later to the specific improvements, which are the subject matter of the present invention. Much of the beginning description will necessarily repeat description of the '537 patent, whereas the later description will describe those improvements, which constitute the present invention.

[0037] In accordance with the objects disclosed above, FIG. 1 illustrates improved table 10 of the present invention including an integral dishwasher. Table 10 is formed generally of a top portion comprised of dining surface 12 and control panel 16 mounted on support base 14. Since the present invention was developed for reasons of aesthetics, efficiency, more sanitary eating area, and ease of use, table 10 is substantially permanently mounted in a selected location, and a water line, a waste line, and electric line (not shown) are appropriately connected to the enclosed dishwasher unit. Dining surface 12 contains sink 22 and control panel 16, which has electrical outlet 26 and a series of dials 24 or switches for operating the dishwasher and an optional warming surface 18. A heating element 18′ is located beneath warming surface 18 (see FIG. 2). Additional optional controls, such as room lights or television, may be similarly installed in control panel 16. It is to be noted that the rectangular shape of table 10 is shown as an example, and other shapes, for example circular, would also satisfy the criteria of the present invention.

[0038] Since the respective outer and inner access covers 20a,20bin conjunction with eating tray 34aare constructed and operate in the same way as outer and inner access covers 20c,20d,in conjunction with eating tray 34b,the description only refers to and describes the improved construction of the present invention in reference to the respective outer and inner access covers 20a,20band eating tray 34a.

[0039] While dining surface 12 could be configured to accommodate a single individual, dining surface 12 is illustrated in the preferred embodiment configured to accommodate at least two people as in FIGS. 1-4. Accordingly, a first outer access cover 20ais in a position suited to a first person being seated at table 10. A second inner access cover member 20boperates in conjunction with outer access cover 20aand both are stored beneath the plane of eating surface 12 when eating tray 34ais positioned in their place as in FIG. 9. Also to be noted is that when tray 34ais positioned, as in FIG. 9, its top surface is substantially flush with the top of dining surface 12 and is illustrated in FIG. 9 with a typical set of dishes and utensils placed for use. Note should also be taken that table 10 is sized as best seen in FIG. 2 to accommodate additional people being seated near its left end as viewed in FIGS. 1 and 2. The respective outer and inner access covers 20aand 20bare adapted to be positioned so as to either cover (as in FIGS. 1, 2, 3, or 10) or uncover (as in FIGS. 7-8) the operative portion of the dishwasher below. As further explained below, one side of table 10 is fitted with a respective pair of outer and inner access covers 20a,20b,and the opposite side of table 10 is fitted with a comparable pair of outer and inner access covers 20c,20d.The respective outer access covers 20aand 20cbasically have two parallel positions, high and low. The high position places their respective surfaces in the same plane as that of the dining surface 12, as shown in FIGS. 1, 3, and 10. The respective low position of outer access cover 20ais illustrated in FIGS. 5, 6, 7, 8, and 9. The outer access covers 20a,20care supported, positioned, latched, and unlatched by the later-explained mechanism.

[0040] By contrast, with regard to the manner in which the outer access covers 20a,20care supported, positioned, latched, and unlatched, the inner access covers 20band 20dare supported and pivotally positioned by means of hinge 90 secured to the body structure 58 of table 10. Thus, inner access cover 20bcan lie flat as in FIGS. 1 and 5 and have its upper surface in the same plane as that of dining surface 12, or it can be pivoted on its hinge 90, be inverted, and reside on top of access cover 20aas in FIG. 8. With this preliminary introduction to the outer and inner access covers and their operation, the description now continues with other aspects of the invention.

[0041] Sink 22 is equipped with an electrically heated water spigot 42 (well known to one skilled in this field) for making instant coffee, tea or soup, in addition to the usual water connection 44. A pot insertion door 28 is located at the left end (as seen in FIGS. 1, 3, and 4) of supporting base 14 for placing larger cooking and serving utensils into the dishwasher unit of the invention. Here it should be noted that with respect to access cover members 20a,20b,20c,and 20dthat the improvements to which the present invention relate are directed primarily to the means employed for supporting and positioning the respective access cover members 20a,20b,20c,and 20d,in a manner which permits the access covers, when closed, to form a very smooth dining surface as best explained in reference to later-referred to FIGS. 5-14.

[0042] Referring now to FIG. 2, improved dining table 10 of the present invention is shown in top plan view with certain of the internal components illustrated in dashed lines. Dish-washing water-distributor arm 30a,tray-washing water-distributor arm 30band pot-washing water-distributor arm 30care positioned within support base 14 in separated, vertically spaced locations along a substantially central line C/L that is parallel to the long dimension of the invention dining table with integral dishwasher. Tray-washing water-distributor arm 30ais relatively small and is positioned substantially high, and dishwashing water-distributor arm 30bis relatively large and is positioned substantially low, as best seen in FIGS. 5-10. Warming surface 18, in which heating element 18′ is enclosed, is located in dining surface 12, in a location between the pair of outer and inner access covers 20a,20band the opposite pair of outer and inner access covers 20c,20d.Warming surface 18 is preferably of a different appearance than dining surface 12 for visibility and safety reasons.

[0043] Referring now to FIG. 3, an end elevation view of the relation of angularly oriented, perforate chutes 36aand 36bis shown dashed in and with pot insertion door 28 in an open position. The upper right and left side panels 40a,40bon the right and left sides (as shown in FIG. 3) of support base 14 are oriented angularly to accommodate the shape of perforate chutes 36aand 36b,thus maximizing the space available for the knees of the users. Chutes 36aand 36bprovide a mesh housing for dishes and utensils through which water can pass to permit thorough washing, see FIGS. 5-10. A pair of eating trays 34aand 34bis shown in FIGS. 3 and 5 in their stored locations in chutes 36aand 36brespectively within support base 14. When the respective outer and inner access covers 20a,20band/or the respective outer and inner access covers 20c,20dare open, as in FIG. 8, one may reach through the opening formed and retrieve eating trays 34aand/or 34brespectively, for use as indicated in FIG. 8. Here it may be noted that when both eating tray 34ais stored for washing and access covers 20a,20bare stored, the inner end of the opening provided overlies and gives access to the dishwasher, whereas the outer end of the opening overlies and gives access to the stored access covers. Eating trays 34aand 34bare configured to fit within either of the openings in dining surface 12, which receives the access covers 20a,20bor 20c,20dwhen closed and to be supported so as to reside substantially flush with the plane of dining surface 12 when in their respective operating locations in such openings. At the completion of a meal, eating trays 34aand 34bare placed in their respective storage locations adjacent dishwashing chutes 36aand 36b,where dishes are placed for washing, see FIG. 10. When all dishes and trays are in their respective positions for washing, access cover members 20a,20band/or 20c,20dare closed securely. The dishwasher unit is operated to wash trays 34aand 34balong with the dishes that have been placed in chutes 36aand 36b.

[0044] FIG. 4 shows an end view of dining table 10 with integral dishwasher as seen in FIG. 3, but with pot insertion door 28 closed, ready for a washing cycle for the pots and pans. The space within table 10 behind door 28 also serves as a storage area for pots and pans when not in use.

[0045] FIGS. 5-14 illustrate the operation of the outer and inner access cover support and positioning mechanism of the present improved invention through a series of sequential positions of the respective outer and inner access covers 20a,20band outer and inner access covers 20c,20dand eating trays 34a,34b.For purposes of illustration and explanation hereafter, only access cover members 20a,20band eating tray 34awill be described in detail with reference to FIGS. 5-14. As previously mentioned, the pair of outer and inner access covers 20a,20band eating tray 34aare adapted to occupy the same opening in dining surface 12, but at alternate times.

[0046] As more general background, and as a reference for the further-detailed description to follow, it may be noted that with the improved construction of the present invention outer access cover 20ais mounted in such a way that while maintaining itself in a substantially horizontal position, it can move somewhat outwardly, downwardly, and then somewhat inwardly from a high position illustrated in FIGS. 1 and 10 to a low position illustrated in FIG. 6, and in which low position it receives and effectively supports the inner access cover 20b,as illustrated in FIG. 8. Access cover 20a's mounting arrangement also enables access cover 20a,while remaining in a substantially horizontal position, to move somewhat outwardly and vertically (see FIG. 5) from its low position illustrated in FIG. 6 and then somewhat inwardly to its high position illustrated in FIGS. 1 and 10. In outer access cover 20a's high position, its inner edge abuts the outer edge of inner access cover 20bas illustrated in FIGS. 1 and 10. When outer access cover 20ais in such high position, as in FIGS. 1 and 10, its top surface resides in the same plane as is occupied by the top surface of dining surface 12 as illustrated in FIG. 10. As later explained, the improved construction of the present invention also enables the outer access cover 20ato be very easily latched and unlatched when in its high position.

[0047] Outer and inner access covers 20aand 20bare not hinged together as in Applicant's '537 patent. Unlike outer access cover 20a,inner access cover 20b,as previously mentioned, is hinged along its outer edge by means of hinge 90 to a fixed bar member 58, and thus can be pivoted from a low position, illustrated in FIG. 8, in which low position inner access cover 20bresides on and is supported by outer access cover 20ato a high position, as in FIG. 10. When inner access cover 20bis in such high position, as in FIG. 10, its inner edge abuts a mating outer edge of dining surface 12, and its outer edge is mated with and abuts the inner edge of access cover 20a,as in FIGS. 1 and 10, which creates the join line J, see FIG. 2, along a fine line, and along which there is no protruding hinge as was the case with the construction of Applicant's '537 patent.

[0048] Also to be understood and kept in mind as general background is that the improved construction of the present invention, as previously mentioned, is configured such that when the respective outer and inner access covers 20aand 20bare stored, as in FIG. 8, the opening previously occupied by access covers 20a,20b,when closed, is provided for accepting tray 34aas seen in FIG. 9.

[0049] The improved construction also includes an arrangement explained later in detail, which enables the inner edge of access cover 20awhen moving into its low position to engage exposed lifter tabs 93, 94 on hinge 90, which causes access cover 20bto tilt upwardly slightly as in FIG. 6, which facilitates grasping and upward pivoting of access cover 20b,to the position as illustrated in FIG. 7 and subsequently to its low position as in FIG. 8. The description now continues with a more detailed description of the just-explained general background directed to the improvements of the present invention.

[0050] Here it should again be mentioned that a specific and important object of the present invention has been that of eliminating any intrusion into the smoothness of the dining surface, such as protrusion of the hinge 54 seen in the '537 patent (see FIG. 8 of the '537 patent) when the access covers are in a coplanar, horizontal position as in FIG. 8 of the '537 patent. A primary object of the present invention is to achieve a relatively smooth hinge-free surface when the access covers are closed as illustrated in FIGS. 1 and 10.

[0051] As the more detailed description of the improved mechanism of the invention for positioning and supporting the access cover members 20a,20bcontinues, it should be noted that the dining tray 34band access cover members 20c,20dcan be positioned either as shown in FIG. 1, FIG. 2, or FIG. 3. When positioned as in FIGS. 1 and 2, it should be noted that the top surfaces of access cover members 20a,20bpresent a substantially smooth surface on either side of a very fine, join line J (FIG. 2), and which surface can be used either as a dining surface or as a work surface. In a second mode shown in FIG. 8, access cover member 20b,which is hinged to a connecting bar 58, is folded so that the top surface of inner access cover member 20brests on the top surface of outer access cover member 20aand below the level of surface 12. In this mode, an opening is formed in surface 12 equivalent in size to that vacated by the now-folded access cover members 20a,20b.This recess receives the tray 34a(FIG. 9) of corresponding size as a work surface, and on which cutlery and dishes can be placed as also seen in FIG. 9. This versatile arrangement is further depicted in FIG. 1, in which access cover members 20c,20dare assumed to be folded and replaced by tray 34bfor use as a dining surface, whereas access cover members 20a,20bremain in place for use as a smooth-surfaced work surface. By contrast, in FIGS. 5 and 6, access cover members 20aand 20bare partly removed from the position in which their respective top surfaces are flush with dining surface 12. In FIG. 10, outer access cover 20ais shown as having an outer surface 41aand inner surface 41b,whereas in FIGS. 9 and 10 inner access cover 20bis shown as having an outer surface 41cand an inner surface 41d.

[0052] Referring next to FIGS. 11-14, it will be seen that access cover member 20amounts on its bottom surface a pair of parallel rods 56a,56b.Rod 56bpivots within associated brackets 56e,56f,and rod 56apivots within associated brackets 56c,56d,the brackets being secured by screws 56g.Rod 56amounts on opposite ends respective levers 71, 72, and rod 56bmounts on opposite ends of respective levers 73, 74. Opposite ends of the respective levers 71-74 pivot on pins P extending inwardly from respective brackets 75, 76. Levers 72, 74 operate under the tension of the spring 81 and levers 71, 73 operate under the tension of the spring 80. Rods 56a,56boperate in unison through the connecting links 87, 88. An additional rod 23 pivots in its mounting brackets 25a,25b,25c,and 25dand its pivotal motion responds to the latched or unlatched condition of a hand pressed pivotal lever 21.

[0053] Lever 21 is spring loaded so that upon release of lever 21, springs 21a,21b(FIG. 11) force lever 21 back into its original position. Lever 21 is fixedly attached to rod 23, which in turn is pivotally mounted to the back or inner surface 41bof access cover member 20aby the previously mentioned brackets 25a,25b,25cand 25d.Brackets 25a,25b,25c,and 25dare fixedly attached to the inner or back surface 41bof access cover member 20aby screws 27. The outermost ends of rod 23 are L-shaped as at 27a,27b.L-shaped ends 27a,27bare releasably received by brackets 29a,29bwhich are fixedly mounted on the underside of dining surface 12 by screws 29c.L-shaped ends 27a,27bof rod 23, when latched, are normally received by brackets 29a,29b,as in FIG. 11, until released, as in FIG. 12, by pressing lever 21.

[0054] Thus far attention has been directed to access cover member 20aand its operating mechanism. Attention will now briefly shift to access cover member 20band its associated mechanism. Access cover member 20bis pivotally connected to bar 58 by hinge 90. Hinge 90 is mounted below dining surface 12 so that when table 10 is being used for food preparation food cannot get into the hinge area. One leaf portion of hinge 90 is fixedly mounted on the face of one edge of bar 58 and another leaf portion is fixedly attached to the underside of access cover 20b.A pair of lifter tabs 93, 94 are fixedly secured at one end to a leaf portion of hinge 90 and extend downwardly therefrom. When access cover member 20ais moved into its most downward position, its inner edge contacts the lower extremities of lifter tabs 93, 94, which causes access cover 20bto be raised a predetermined amount, as seen in FIG. 6. This raised movement of access cover 20ballows the user of the apparatus of the present invention to be able to easily grasp the edge of access cover 20band manually raise access cover 20band move it to the position of FIG. 7 and then to the position of FIG. 8.

[0055] Description will now shift to further aspects related to operation of the mechanism of the present invention. In this regard, it is again mentioned that only access covers 20a,20bare described in detail as access cover members 20c,20dare identical in structure and operation. Attention is next directed specifically to FIGS. 5-13.

[0056] The cross sectional elevation view of FIG. 10 and bottom view of FIG. 11 illustrate access cover members 20a,20bin a closed position as shown in FIG. 1. In the positions associated with these three figures, the top surfaces of access covers 20a,20bare flush with the top surface of dining surface 12 of the improved dining table 10. In the position being illustrated, tray 34aand all of the dishes are stored underneath dining surface 12, see FIG. 10. Thus, if an individual wants to remove the dishes and set the table for eating on eating tray 34a,he or she first grasps lever 21 and presses it inward, which in turn depresses springs 21a,21b.As a result, L-shaped ends 27a,27bof rod 23 are released from brackets 29a,29b.Outer access cover 20ais then moved downward into the partly open position associated with that illustrated in FIG. 5 and FIG. 12. During this operation, rods 56aand 56bmove into the position shown in FIGS. 5 and 12. Once lever 21 has been depressed and access cover 20ahas begun to be moved downward, access cover 20acan be moved further downward to its lowermost position as illustrated in FIG. 6. When access cover 20ais in its lowermost position, the inner edge of access cover 20acontacts the exposed extremities of lifter tabs 93, 94. Once access cover 20ais in its lowermost position, as in FIG. 6, the inner access cover 20bis forced upward a predetermined small amount by lifter tabs 93, 94, see FIG. 6. The operator can easily grasp the raised edge of access cover member 20band pivot it upward by grasping the forward edge thereof and raising access cover member 20band moving it to the vertical position illustrated in FIG. 7. Access cover member 20bcan then be moved further forward until it reaches the position illustrated in FIG. 8 where surface 41aof access cover member 20aand surface 41c(FIG. 8) of access cover member 20brest against each other.

[0057] Referring now to FIG. 8, at this stage tray 34ais being moved from its storage and cleaning position within base 14, upwardly and outwardly in the direction of arrow B. Eating tray 34ahas a guide 46, for example a roller, mounted to each of its lower corners (one shown) by bracket 48. Guide 46 is formed with a circumferential groove that engages track 50 to guide the movement of eating tray 34a.Track 50 is made of round rod material, in the preferred embodiment. Other forms of guide and track are available to accomplish similar control. A pair of stops 60, only one of which is shown in FIG. 8 are mounted to the upper inner corner (one shown) of chute 36aand a pair of supports 60′ are mounted to the upper outer corner (one shown) of chute 36ato be at different heights relative to eating surface 12. As illustrated in FIG. 8, guides 60 assist in guiding the movement of eating tray 34aout of its storage position.

[0058] FIG. 9 shows eating tray 34aas it is placed to provide continuity of eating surface 12. A mortised edge M is formed on the inner edge of eating tray 34aand the mating edge of dining surface 12 to securely locate and support the rear of eating tray 34a.In this position, the middle area of eating tray 34arests on support 60′ and the front edge thereof rests on a mating mortised edge of inner part 41b,thereby securely supporting eating tray 34aat three points. In this operating position of eating tray 34a,as illustrated in FIG. 9, guide 46 has been pressed into a rearwardly extending spur portion of track 50 and is pressed against the lower surface of dining surface 12 so that dining surface 12 is substantially sandwiched between guide 46 and mortised edge M.

[0059] FIG. 10 illustrates the dining table with integral dishwasher 10 as it is ready for a washing process. Eating tray 34ahas been returned to its storage position with guide 46 near the lower end of track 50 and the upper end of eating tray 34aresting on stop 60. Access cover member 20ais positioned flush with dining surface 12 with mortised edges M of dining surface 12 and access cover member 20bengaged. Access cover member 20ais fitted with gasket material (not shown) so as to contain spraying water coming from water distribution arms 30a,30b.A typical set of dishes is shown in perforate chute 36a.A locking mechanism, previously described lever 21, springs 21a,21b,rod 23, and brackets 29a,29b,function to keep access cover members 20a,20bsecurely held in the illustrated position to prevent accidental opening during a washing cycle and so that if downward pressure exerted on the outer end thereof does not cause access cover member 20ato dislodge.

[0060] When the dishwasher function operates, upper water distribution arm 30asprays water in the direction of arrow C (FIG. 5) onto the exposed upper surface of eating tray 34a,and lower water distribution arm 30bsprays water in the direction of arrows D (FIG. 5) onto the exposed lower surface of eating tray 34aand the dishes in chute 36a.A further water distribution arm 30csprays upwardly to wash pots in basket 32 (see FIG. 3).

[0061] It will be appreciated that after eating tray 34ahas been positioned as in FIG. 10, there may be excess water sprayed towards the inwardly located portions of the sides of the opening in which tray 34aresides. Therefore, the apparatus of the invention makes provision for establishing barriers to any dishwasher spray directed towards the inwardly located portions of the sides of the opening in which tray 34aresides. This spray barrier apparatus is shown in FIGS. 11-13 and 15 and comprises formed sheet metal spray barriers 110, 111. Each spray barrier is mounted such that it can move towards and away from the opposite spray barrier under the tension of springs in spring assemblies 114, 115 and also so that it can also move in and out under the tension of springs 120, 121 and 122, 123. Thus, after tray 34ahas been positioned as in FIG. 10, spray barriers are established by the spray barriers 110, 111 so as to prevent spray water from reaching the inwardly located portions of the sides of the opening.

[0062] The invention further recognizes that there are a substantial number of single person households. In such a single person situation, eating may most commonly be done at a kitchen counter rather than at a table. The present invention can be built into a counter with a single access cover and a single chute for one-side use. Such a one-sided mechanism could similarly be built into a dining table if desired.

[0063] The above detailed description of a preferred embodiment of the invention sets forth the best mode contemplated by the inventor for carrying out the invention at the time of filing this application and is provided by way of example and not as a limitation. Accordingly, various modifications and variations obvious to a person of ordinary skill in the art to which it pertains are deemed to lie within the scope and spirit of the invention as set forth in the following claims.
