WASHING MACHINE 1927, Serial No. 205,857. Renewed August 20; 1931.
This invention relates to washing machines and aims particularly to provide a simple, inexpensive, compact, and effective dish washing machine for household use.
Objects of the invention are to provide, in such a machine, a compact pump and sump and a combined filling, drain, and overflow pipe which automatically drains the pump casing as well as the sump.
Other objects and advantages of the invention are hereinafter set forth in connection with a detailed description of the machine embodying the various features of the invention which are shown in the accompanying drawings in which Fig. 1 is an end view of the machine showing the machine placed directly in a sink (showing in vertical section) with the standpipe in draining position;
Fig. 2 is an enlarged end elevation of the machine with the movable top section in closed position, sectioned on the line 22 of Fig. 4;
Fig. 3 is an enlarged front elevation of themachine, sectioned on line 33 of Fig. 2;
Fig. 4 is a plan view of the machine sectioned on the line 4-4 of Fig. 2, showing the strainer broken away, and including a phan tom view of the tank;
Fig. 5 is an enlarged vertical section of the sump and pump unit taken on the line 55 of Fig. 3, showing the distributor mounting in axial section;
Fig. 6 is a section of the sump and pump unit taken on the line 66 of Fig. 2; and
Fig. 7 'is a section of the sump and pump unit on the lines 77 of Figs. 3, 4, 5' and 6, showing the pump involute drain channel.
The dish washing machine illustrated is of the type in which soapy water or other wash- V ing medium is drawn from a sump or reservoir 1 by a motor-driven pump 2 and forced into a distributor 3, such as a rotary wash arm, from which it is projected against the dishes. The water which has passed over the dishes drains back into the sump so that it may be used repeatedly.
The casing of the machine is made entirely of sheet metal. It may consist of only four parts, each of which may be drawn or otherwise formed from a single piece of sheet metal. These parts include a supporting shell 10, a shallow tank 11, a fixed cover section 12 and a movable cover section 13. The supporting shell 10 contains the motor, pump, and sump, and may be made of smail area. owing to the fact that the pump and sump are combined in a singleunit, as hereinafter explained. The small area of the supporting section facilitates placing the machine on a sink, as shown in Fig. 1, pr on a wash tub, without interfcrence with the faucets. The shallow tank 11 is secured to and rests on the upper edge of the'supporting shell 10 and is of larger area than the shell. The bottom of the tank slopes inwardly to an opening 14 leading to the pump casing 31 forms part of one of the side walls of the sump and contains an opening 35 for the passage of liquid from the sump to the pump casing. The discharge neck or conduit 36 of the pump casing rises within the sump 1 and extends into the tank 11 through the opening 14'. The impeller 37 of the pump is driven by an electric motor 38 mounted on a strip 39 extending across the inturned lower edge 40 of the supporting shell '10. The impeller shaft 41 passes through two stufling boxes 42 in the outer wall l3 of the pump casing 31. A drain passage 44 in the wall 43 diverts any liquid which may leak through the inner stuffing box and prevents it from entering a bearing 45 in which the shaft 41 is supported.
To provide for draining both the sump and the pump casing, the unit 30 has at one of its lower edges a hollow cylindrical extension or sleeve 46 which communicates with the sump through an opening 47. A
A combined filling, overflow, and drain pipe 50 extends through the sleeve 46 and is turnable therein. The inner end of the pipe 50 is closed by a plug 52 while the outer end otthe pipe extends through a hole 53 in the shell 10 and is turned nearly at right angles to rest on the pipe to form an open standpipe 54. Lengthwise movement of the pipe 50 is prevented by a fixed collar 55 and a spring-pressed collar 56 engaging opposite ends of the sleeve 46 (see Fig. 3). The spring-pressed collar 56 serves also to create friction which holds the pipe 50 and its standpipe 54 in any position into which they may be turned. Turning of the pipe 50 is positively limited by the engagement of steps 57, 58 on a collar 59 with a strip 60 which extends across the bottom of the shell 10. The stops are placed so that the pipe 50 may be turned between a position in which its standpipe 54 is turned vertically upward (as shown in Fig. 3 and in dotted lines in Fig. 2), and a. position in which the standpipe 54 is inclined rearwardly and slightly downward (as shown in Fig. 1 and in dot and dash lines in Fig. 2).
The portion of the pipe 50 within the sleeve 46 contains a lateral port 62 which registers with the drain opening 47 of the sump in all positions of the pipe 50 and with the drain channel 48 from the pump casing only when the standpipe is turned down (see Figs. 2, 3, 4, and Figs. 5 and 7 which show the position of the port 62 when the standpipe is turned down to the position indicated by dot and dash lines in Fig. 2).
When the standpipe 54 is turned upward, the sump 1 and tank 11 may be filled through the pipe 50, for example, by means of a rubber hose. Alternatively, the machine may be filled by raising the door 13 and pouring water directly into the tank 11. In either case the standpipe 54 acts as an overflow pipe determining the level of the liquid in the tank 11 and preventing the liquid from rising high enough to interfere with the rotary distributor 3, hereinafter described. The standpipe 54 s maintained in upright position during the operation of the machine, thus preventing the escape of water from the sump, while at the same time the wall of the pipe 50 prevents any water from passing out of the pump casing through the drain channel 48.
lVhen the standpipe 54 is inclined downwardly, both the sump and the pump casing are completely drained through the pipe 50 and the standpipe. This not only prevents stagnant water from collecting in the'pump casing, but is of particular advantage in a machine intended for household use, since the soapy water used in Washing the dishes may be quickly and completely withdrawn from the machine to make ready for the introduction of clean water for rinsing.
The plug 52 and the collars 55, 56 and 59 are detachable from the pipe 50 so that the pipe may be reversed to extend through an opening 53 in the shell 10 placing the standpipe 54 at the left-hand end of t e machine, as shown in Fig. l.
The rotary distributor 3 is of the type customarily known as a rotary wash arm.
The operation of the machine will, it is believed, be readily apparent from the above description. In the use of the machine it is desirable, after inserting a rack of dishes through thedoor 13, to fill the machine with hot soapy water and operate it for a suflicient time to cleanse the dishes, and then to drain off this water, refill the machine with clean hot water, and operate it again for a few moments to rinse the dishes.
Certain features of the machine which has been described form the subject matter of an application filed by me on. March 5, 1926, Serial No; 92,387, of which the present application is a division, filed in order to present claims removed from the aforesaid application, in compliance with a final requirement of division made by the Patent Office.
