Detailed Description of the Preferred Embodiment
Referring to the drawings, and initially to FIGS. 1, 2 and 3, a mechanism in accordance with the present invention is provided for drying and frying meat, particularly pork and fish, and comprises generally a base 10 having a pot 20 pivotally supported at one side at a pivot axle 21, the pot 20 is rotatable about the pivot axle 21 (FIG. 6) so that the meat disposed in the pot 20 can be easily removed. The base 10 includes an open upper portion for receiving the lower portion of the pot 20. A table 11 is disposed on the front portion of the base 10.
A gear 12 is rotatably disposed on a support 14 and is engaged with a pinion 16 which is fixed on the spindle 18 of a motor 17 so that the gear 12 can be rotated by the motor 17. A post 15 has one end pivotally coupled to the peripheral portion of the gear 12 and has the other end pivotally coupled to the lower portion of the pot 20, preferably close to said pivot axle, such that the pot 20 can be caused to rotate about the pivot axle 21 by the motor 17, best shown in FIG. 6, and such that the dried and fried meat can be easily discharged from the pot 20. A pair of projections 19 extend outward from the side portions of the pot 20 for engagement on the upper portion of the base 10 in order to support the pot 20.
The pot 20 has a curved lower portion located in the upper portion of the base 10 and having a stove 22 disposed in the bottom thereof, the stove 22 is connected to a gas supplying source, such as a gas tank (not shown) disposed in the base 10, for heating the pot 20 and the meat disposed in the pot 20. A bracket 23 is disposed on the rear portion of the pot 20 for supporting two motors 24, 25. The pot 20 includes an open top enclosed by a two-piece cover which includes a rotatable board 26 pivotally coupled to a fixed board 27 which is fixed on the upper and rear portion of the pot 20. A transparent window 28 is provided in the rotatable board 26 so that the interior of the pot 20 can be seen, and two fans 29 are disposed in the fixed board 27 for discharging the steam or humidity contained in the pot 20.
A tube 30 is rotatably and laterally disposed in the upper portion of the pot 20 and includes a gear 31 fixed on one end thereof. As is best shown in FIG. 4, the gear 31 is coupled to a pinion 32 by a belt 34 and the like, the pinion 32 is fixed on the spindle 33 of the motor 24 such that the gear 31 and the tube 30 can be rotated by the motor 24. A pair of microswitches 35 are disposed on the side portion of the pot 20, and a stop 36 is disposed on the belt 34 and movable and contactable between the microswitches 35 in order to control the rotational directions of the motor 24.
Referring next to FIGS. 4 and 5, and again to FIG. 3, a stirrer such as a plate 40 having an inverted Vshape has two ends fixed to the end portions of the tube 30 by a pair of beams 41 and is located close to the curved inner and bottom surface of the pot 20. The plate 40 and the beams 41 are caused to swing by the motor 24. The tube 30 is located in the center of the curvature of the inner surface of the pot 20 such that the plate 40 is movable along the inner surface of the pot 20, best shown in FIG. 4. A rod 42 is rotatably engaged between the beams 41 and has a panel 43 fixed integral thereon, and a plurality of extensions 44 formed integral on the panel 43. A pinion 45 is fixed on one end of the rod 42.
A pinion 50 and a gear 51 are fixed on a shaft 52 which is rotatably supported in the other end of the tube 30 distal from the gear 31 by the bearings 53, 54, in which the pinion 50 is aligned with the pinion 45 and coupled to the pinion 45 by a belt 55 and the like so that the rod 42 and the panel 43 and the extensions 44 can be caused to rotate when the pinion 45 rotates. As shown in FIGS. 1 and 5, the gear 51 is coupled to a pinion 250 by a belt 56, and the pinion 250 is fixed to the spindle of the motor 25 such that the gear 51 can be rotated by the motor 25 and such that the panel 43 and the extensions 44 can be caused to rotate about the rod 42 by the motor 25.
In operation, the plate 40 is caused to swing in the pot 20 by the motor 24 for scraping the meat stick on the inner and bottom surface of the pot 20 and the panel 43 and the extensions 44 are caused to rotate about the rod 42 for stirring the meat contained in the pot 20, whereby, the meat contained in the pot 20 can be heated and dried by the stove 22 and can be stirred by the panel 43 and the extensions 44.
Referring next to FIG. 6, after drying and frying operations, the pot 20 is caused to rotate about the pivot axle 21 by the motor 17 such that the dried an fried meat can be easily discharged from the pot 20 and can be easily collected in a pan 60 disposed on the table 11.
Accordingly, meat can be stirred thoroughly by the mechanism in accordance with the present invention and the dried and fried meat can be easily discharged.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
