RACK STRUCTURE FOR DISHWASHER Filed Aug. 3, 1964 F'IGI H QNVENTOR DONALD S. CUSHING H \S ATTORNEY United States Patent 3,269,790 RACK STRUCTURE FOR DISHWASHER Donald S. Cashing, Louisville, Ky., assignor to General Electric Company, a corporation of New York Filed Aug. 3, 1964, Ser. No. 387,042 4 Claims. (Cl. 312328) This invention relates generally to dishwashers and, more particularly, to an improved dish supporting rack for an automatic dishwasher.
Two major problems which the dishwasher industry continually faces are capacity of the dishwasher and ease of loading and unloading. Quite often the solution of one of these problems aggravates the other. For example, capacity may be increased by positioning the individual dishes closer together or by using space previously unused because of its relative inaccessibility. On the other hand, ease of loading and unloading may be increased by avoiding the use of relatively unaccessible portions of the dishwasher wash chamber or by utilizing elaborate swing-out racks which necessitate additional unused space, within the wash chamber, for the rack to swing free. Of course, it would be advantageous to have a dish supporting rack which increased both capacity and ease of loading,
Accordingly, it is an object of this invention to provide an improved dish supporting rack for an automatic dishwasher.
It is another object of this invention to provide a dish supporting rack for an automatic dishwasher which greatly increases the ease with which dishes may be loaded onto the rack.
It is another object of this invention to provide a dish supporting rack for an automatic dishwasher which utilizes substantially all of the useable space within the dishwasher wash chamber.
It is an additional object of this invention to provide a dish supporting rack for an automatic dish-washer which is secured to, and carried by, the closure member for the dishwasher.
It is a further object of this invention to provide a dish supporting rack for an automatic dishwasher which positions the dishes supported thereby in such a manner that the weight of the dishes assists in sealing the closure member to the dishwasher cabinet.
Briefly stated, in accordance with one aspect of the present invention, there is provided an automatic dishwasher comprising an outer cabinet having a wash chamber therein. A door is provided in one wall of the cabinet to provide access to the wash chamber and a dish supporting rack is carried by the door and extends into the wash chamber when the door is closed. In a specific embodiment of the present invention the dish supporting rack is rigidly secured to the door and solely supported by the door so that the rack pivots out of the wash chamber when the door is opened thereby to facilitate loading and unloading of dishes onto the dish supporting rack.
While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter which is regarded as the invention, it is believed the invention will be better understood from the following description taken in connection with the accompanying drawings, in which:
FIGURE 1 is a side view, partially cut away to show details, of a dishwasher utilizing the dish supporting rack of the present invention, with the dishwasher door in the open position;
FIGURE 2 is a View similar to FIGURE 1 with the dishwasher door in the closed position; and
FIGURE 3 is a partial sectional view taken along line 3-3 of FIGURE 2.
ice
Referring now to the drawings, and particularly to FIGURES l and 2, there is illustrated an automatic dishwasher 10 having an outer cabinet 11 defining therein a wash chamber 12. A closure member or door 13 is provided in one wall of cabinet 11 to provide access to wash chamber 12. A bottom wall 14 defines the lower extremity of Wash chamber 12 and is configurated to gradually slope toward an outlet 15.
Positioned below bottom wall 14, but within cabinet 11, is a motor 16 which drives a pump 17. Motor 16 is of the electrically reversible type well known in the electric motor art and may be directly mechanically linked to pump 17. The inlet to pump 17 communicates with outlet 15 by means of conduit 18. Pump 17 is a two- Way pump, such type pumps being well known in the pump art, whereby, upon rotation of motor 16 in one direction, pump 17 will pump fluids from conduit 18 out through conduit 19, In the opposite direction of rotation of motor 16, pump 17 will pump fluids from conduit 18 out through conduit 20. Conduit 19 communicates with the household sewer system (not shown) so that when pump 17 pumps through conduit 19, dishwasher 10 is drained into the sewer. Conduit 20 communicates with a spray device 21 which is designed to effectuate a wash action within chamber 12 when any fluids are pumped through the spray device. Spray device 21 may be a stationary tube having orifices therein or it may be an oscillating, rotating or reciprocating device, the exact arrangement not being critical to the present invention.
A sequence control means 22 is provided with a manually operable control knob 23 and is electrically connected to the motor 16 to control motor 16 through the necessary sequence of operations to effectuate a complete wash cycle within wash chamber 12. Many sequence control means are presently commercially available and they are well known in the washing machine art so that it is unnecessary to explain in detail the structure and operation of the sequence control means 22.
At the rear of cabinet 11, an additional member 24 is provided in spaced relation to cabinet 11 to thereby define an enclosure 25. Enclosure 25 houses a portion of conduit 19 and also houses a water inlet valve 26 which controls the admission of water from the standard household plumbing system (not shown). A water inlet opening 27 is provided in the rear wall of cabinet 11 so that when valve 26 is opened, the water will be directed into wash chamber 12. It is, of course, understood that sequence control means 22 also controls the opening and closing of inlet valve 26 in the manner well known in the automatic washing machine art.
In accordance with the present invention, there is provided a dish supporting rack, designated generally as 28, adapted to support a plate 29. Supporting rack 28 is carried by door 13 so as to pivot into wash chamber 12 when door 13 closes and to pivot out of wash chamber 12 when door 13 is opened. Supporting rack 28 includes legs 30 and 31 which may be rigidly secured to door 13. Legs 30 and 31, as more clearly illustrated in FIGURE 3, are of generally elongated U-shape, having the distal ends of the U secured to the inner surface of door 13. Extending between legs 30 and 31 is member 32 which provides rigidity to legs 30 and 31 and also serves to stabilize plate 29 when door 13 is closed, Extending generally away from door 13 and secured to leg 31 is member 33. Member 33 may be integral with member 32, as illustrated, or it may be a separate member secured thereto by suitable means such as welding or brazing. Secured to member 33 near its end most remote from door 13, is member 34 which extends generally parallel to door 13.
When door 13 is closed, leg 31 and member 34 serve to support plate 29 as shown in FIGURES 2 and 3. When door 13 is opened, legs 30 and 31 serve to support plate 29 as shown in FIGURE 1. As best illustrated in FIGURE 3, members 32 and 33 serve to stabilize the plates from tipping and nesting while legs 30 and 31 support the edge of the plate when door 13 is open and leg 31 and member 34 support the edge of the plate when door 13 is closed.
Support means such as hook 36 may be provided on the inner surface of door 13 to support glasses or cups above plates 29. Similarly, hooks 37 may be provided on the rear Wall of cabinet 11 above plates 29 to thereby utilize substantially all of the volume of wash chamber 12 by supporting cups and glasses in that portion of chamber 12.
Thus, it can be seen that the structure of the present invention provides a dish supporting r-ack which greatly enhances the ease of loading and unloading dishes without the sacrifice of substantial space within the dishwasher of wash chamber. Moreover, the supporting rack 28 is arranged so that when door 13 is closed the weight of rack 28 and the dishes supported thereby assist in sealing door 13 to cabinet 11.
As will be evident from the foregoing description, certain aspects of the invention are not limited to the particular details of construction of the example illustrated, and it is contemplated the various other modifications or applications will occur to those skilled in the :art. It is therefore intended that the appended claims cover such modifications and applications as do not depart from the true spirit and scope of the invention.
