Background of the Invention
1. Field of the Invention
This invention relates to beverage brewer structures and in particular to means for mounting and protecting the basin of a pour-in brewer beverage structure in the normal use thereof.
2. Description of the Prior Art
In one form of beverage brewer, a basin is provided within a housing for receiving water to be heated in an associated hot water heating tank. The top wall of the housing is conventionally provided with an opening through which the poured-in water may be delivered into a portion of the basin.
It is also conventional in certain prior art beverage brewer structures to provide a warmer station on the upper wall of the beverage brewer to receive a decanter, or similar receptacle, and maintain the coffee or other beverage in the decanter at serving temperature. For this purpose, the top wall is provided with an opening and the warmer station structure is mounted to extend across the opening with portions thereof depending into the space in the cabinet below the top wall.
It has further been conventional to mount the basin on the housing as by corner support means.
In one improved form of beverage brewer structure, the water heating means comprises an instantanteous-type heater wherein the cold water is heated as it flows through a body of heated metal. It has been conventional to mount the instantaneous-type water heater on a shelf portion of the housing. The shelf portion has been cantilevered forwardly from a rear upright of the housing so as to overlie the space in which the brewing cartridge and receiving decanter are disposed during the brewing operation.
One example of a beverage brewer structure utilizing such a cantilevered upper portion having a basin for receiving brewing water is shown in U.S. Pat. No. 3,387,903 of Harvey R. Karlen, which patent is owned by the assignee hereof. In this patent, the basin extends upwardly through the top wall of the top portion of the cabinet.
In U.S. Pat. No. 3,589,273 of Harvey R. Karlen, which patent is also owned by the assignee hereof, the basin is disposed within the upper portion of the outer housing for delivering the poured-in water to a subjacent heating tank in an upright rear support portion of the housing. The basin includes a removable lid having an inlet opening in one portion thereof.
Summary of the Invention
The present invention comprehends an improved beverage brewer structure wherein a basin is mounted in an upper portion of an outer housing for receiving poured-in water from a decanter or the like through an opening in the top wall of the housing. The top wall may further support a warmer station which may extend across an opening in the upper wall overlying a portion of the basin within the housing.
The invention comprehends providing means for preventing liquid which might inadvertently pass downwardly through the warmer station opening from falling into the basin and thereby contaminating the brewing water.
In the illustrated embodiment, this means comprises a wall member which is mounted to the basin to overlie the portion thereof underlying the warmer station opening.
The wall member may be inclined so as to deflect the liquid which may fall from the warmer station opening to an edge of the basin. Further, the wall member may be sufficiently heated as by heat transfer association with the water heating means in the brewing apparatus so as to evaporate water which may fall downwardly through the warmer station opening thereonto.
The wall member may be secured to the basin by cooperating embracing edge portions thereof. The basin may be supported on upstanding supports which may be carried on brackets associated with a shelf portion of the housing defining the bottom of the cantilevered upper portion thereof. The supports and basin edge portions may be provided with locating means for accurately locating the basin relative to the underlying water heating device.
In the illustrated embodiment, the water heating device may comprise an instantaneous-type heater which receives the water from the basin and which heats the water as it passes therethrough to the subjacent brewing cartridge.
The shelf brackets may be secured at their rear end to the upper end of the rear upstanding portion of the housing so as to reinforce the shelf in defining the bottom of the forwardly cantilevered upper portion of the housing.
The beverage brewing structure may further include a conduit for delivering pressurized water to the basin alternatively to the pouring in of the water thereinto in effecting the desired brewing operation. The invention comprehends the provision in the overlying wall member of an opening for passing the end of the delivery conduit downwardly therethrough to deliver the pressurized water to the basin in the portion underlying the wall member. The wall member further defines means for preventing splashing of water upwardly from the basin either from the poured-in water or from the pressurized delivered water, from that portion of the basin underlying the wall member.
Thus, the invention comprehends an improved beverage brewer which is extremely simple and economical of construction while yet providing the highly desirable features discussed above in a novel and simple manner.

Description of the Preferred Embodiment
In the exemplary embodiment of the invention as disclosed in the drawing, a beverage brewer structure generally designated 10 is shown to comprise illustratively a coffee brewer provided with an outer cabinet 11 including a base portion 12, an upstanding rear support portion 13, and a cantilevered head portion 14. A removable brewing cartridge generally designated 15 may be selectively supported on a slide carrier 16 provided on a lower shelf 17 of the head portion 14. The base may be provided with a warmer station 18 for carrying a decanter or the like to receive the brewed coffee from cartridge 15 and to maintain it at brewing temperature. Suitable electrical control switches 19 may be provided for controlling the operation of the beverage brewer.
The head portion 14 of cabinet 11 defines a top wall 20. A forward portion of the top wall defines an inlet opening 21 which may be selectively closed by a removable lid 22. The top wall further defines a second opening 23 in a rear portion thereof in which is mounted a second warmer station 24. As shown in FIG. 5, the warmer station 24 extends substantially across the opening 23. As further shown in FIG. 5, the pouring opening 21 is provided with a filter screen 25 for screening out material in the brewing water delivered therethrough to a subjacent basin 26 within the head portion 14 of the brewer.
Basin 26 comprises an upwardly open basin having a peripheral flange portion 27. The basin defines a first, forward portion 28 underlying the pour-in opening 21, and a second, rearward portion 29 underlying the warmer station opening 23. The basin further defines a bottom wall 30 having a connector 31 connecting the basin to a subjacent water heating device 32 which may comprise a conventional instantaneous water heater adapted to heat the coffee brewing water as it flows therethrough to the subjacent brewing cartridge 15.
As shown in FIG. 5, the poured-in brewing water W, when poured through the opening 21 from a suitable supply container, such as a decanter D, impinges on the basin bottom wall 30 so as to have some splashing action which may tend to cause portions thereof to splash upwardly through the rearward basin space. The invention comprehends providing a wall member generally designated 52 in overlying relationship to the basin space 29 so as to prevent splashing of a portion of the brewing water outwardly from basin space portion 29 as illustrated in FIG. 5.
As shown in FIG. 4, wall member 52 defines a flat top portion 33, triangular side portions 34, turned side securing portions 35, and a rearwardly depending apron portion 36. The turned securing portions 35 embrace the flange 27 of the basin so as to secure the wall member 52 to the basin with the top wall portion 33 thereof overlying the basin rear portion 29 and underlying the top wall opening 23.
As further illustrated in FIG. 5, liquid which may inadvertently pass down through warmer station opening 23, such as may inadvertently splash from the water delivered from decanter D, or which may pass downwardly from a decanter D' carried on the warmer station 24, is prevented from flowing into the brewing water in the basin by the wall member 52 which thusly acts as a deflector means for preventing contamination of the brewing water by such liquid. The rearward downward inclination of the top wall portion 33 effected by the triangular sidewall 34 causes such liquid to tend to flow rearwardly and downwardly to pass over the rearward apron 36, as illustrated in FIG. 5. However, the wall member is further in heat transfer association with the water heating device 32 as it is mounted above the heating device 32 and, thus, functions to cause evaporation of such liquid falling onto the wall member portion 33 so as to permit elimination of such liquid where only small leakage of the liquid occurs through the opening 23.
The invention further comprehends that the delivery of the brewing water to the basin may alternatively be effected through a conduit 37 connected to a suitable pressurized source (not shown) and having a delivery end portion 38 provided with a distal downturned end 39 extending through a suitable opening 40 in the wall member portion 33 so as to deliver the pressurized water directly into the basin rear portion 29 through the wall member 52. A suitable annular seal 41 may be provided for sealing the distal end 39 to the wall member portion 33 to avoid passage of liquid from opening 23 downwardly through opening 40 into the basin.
As shown in FIG. 5, the wall member 52 further is disposed so as to prevent splashing of water from the pressurized source conduit outwardly from basin portion 29 so as to provide a similar splash control functioning relative to either the poured-in water flow or the pressurized source water flow as utilized. Further, the wall member 52 serves as means for accurately locating the pressurized source delivery end 39 relative to the basin.
As best seen in FIG. 4, the basin may be supported on a pair of upright supports 42 at opposite sides thereof, each having an outturned top support portion 43 adapted to support the flange 27 of the basin. The supports may be further provided with a tongue 44 adapted to be received in a notch 45 in the basin flange 27 so as to accurately locate the basin in relationship to the subjacent water heating device 32. The turned securing portion 35 of the wall member 52 may embrace not only the flange 27 but also the support portions 43 of the upright supports 42, as shown in FIG. 6, so as to lock the basin to the support without additional securing being required in the assembly.
As further shown in FIGS. 4 and 6, the supports 42 may be secured to a pair of brackets 46 extending longitudinally fore-and-aft at opposite sides of the shelf 17 of the head portion 14 of cabinet 11. The supports 42 may be secured as by welding to the brackets and are preferably inclined so as to converge toward the basin, thereby providing a resilient biasing support by the supports against the opposite sides of the basin. The brackets may be secured to the upper end 47 of the rear upright support 13 of the housing by suitable screws 48 and the forward ends 49 of the brackets may be secured to the forward portion of the shelf by suitable means, such as welding 50. As further shown in FIG. 5, the water heating device 32 may be mounted to the shelf by suitable screws 51 extending through the shelf 17 and engaging supporting legs 53 of the heating device.
The electrical connections 54 to the heating device 32 may be supported by suitable bracket 55 mounted to the shelf, as seen in FIG. 5. As shown, the controls 54 are disposed subjacent the basin and forwardly of the rear apron 36 so as to avoid dropping of any liquid from the wall member 52 onto the controls.
Thus, the improved beverage brewer structure provides means for effectively preventing liquid from passing downwardly from the warmer station opening into the basin. The same means is utilized to effectively position the water delivery conduit from a pressurized source when utilized. The same means effectively prevents splashing from a rearward portion of the basin with respect to both water poured in from a decanter through the normal pour-in opening of the apparatus or from the pressurized source conduit. Still further, the same means provides means for securing the assembly of the basin, support and protective means together without additional connecting means being required.
The water deflector means is further arranged to be in heat transfer association with the water heating means of the apparatus so as to further define means for dissipating by evaporation liquid which may fall downwardly through the upper warmer station opening thereonto.
The invention, as discussed above, further provides improved means for supporting the basin on the upright rear support of the cabinet through the intermediate use of brackets which further reinforce the shelf portion of the cabinet head and, thus, provide improved facilitated assembly and positive cantilevered support of the head portion of the cabinet. The housing is arranged so that the screws utilized for securing the brackets to the rear upright support portion of the housing also secure the shelf thereto for further facilitated construction and assembly.
The foregoing disclosure of specific embodiments is illustrative of the broad inventive concepts comprehended by the invention.
