WASHING MACHINE ovERFLow CONTROL UNIT Unite Calif.
Filed Aug. 20, 1962, Ser. No. 217,920 7 Claims. (Cl. tis-208) The present invention relates to control units for use with domestic appliances, such as washing machines; and it relates more particularly to an improved control unit lfor use with an `electric washing machine which responds to an overflow condition in the drainage system associated therewith.
Domestic washing machines are presently in widespread use in the homes and other dwellings across the country. Most present-day washing machines are of the automatic type which automatically cycle through various operations until the clothes are completely washed, rinsed and partially dried.
The usual automatic washing machine is coupled to pressurized hot and cold Iwater lines, and it usually includes a drain tube through which the dirty water is pumped from the machine. The drain tube from the washing machine is usually inserted in a stand-pipe which, in turn, is coupled to the household drainage system.
The normal procedure is for the housewife to place a load of laundry in the washing machine, and to set the machine and leave it unattended. The machine then automatically cycles through its various operations, and when the wash is completed, the machine turns itself off.
Problems have arisen, however, in that should the household drainage system become plugged for any reason, the stand-pipe will overilow. A large amount of water is used in the typical automatic washing machine, and in the event of overflow, sufficient water is pumped out of lthe machine to dood through the household and produce considerable damage.
An object of the present invention is to provide an improved control unit for `detecting abnormal rises in the water level in the stand-pipe, and which responds to such rises to turn off the electric power to the washing machine and/or to sound an appropriate audible alarm.
Another object is to provide such an improved control unit which is relatively simple and inexpensive to `construct, and which can be easily installed into existing washer/ stand-pipe combinations.
Other features and advantages of the invention will become apparent from a consideration of the following description, when the description is taken in conjunction with the accompanying drawings, in which:
FIGURE l is a diagrammatic representation of a washing machine and stand-pipe combination, and which includes a control unit constructed in accordance with the invention for de-activating the washing machine upon an abnormal rise of water level in the stand-pipe;
FIGURE 2 is an enlarged View of the control unit of the invention mounted on the stand-pipe of FIGURE l, the view being taken along the line 2-2 of KFIGURE l; and
FIGURE 3 is an electric circuit diagram of the system of the invention.
The representation of FIGURE 1 includes a usual automatic washing machine 10. This washing machine may be of any known type, and it is capable, for example, of automatically washing clothes in the manner described above.
The washing machine is provided with an electrical cord 12 which normally is plugged into the electrical energizing outlet of the household in which the washing machine is installed. The washing machine 10 also in- 3,69 l ,l ll Patented May 28, 1963 "ice cludes a drain tube, or hose, 14 through which the dirty water from the washing machine drains, as the machine progresses from cycle to cycle during its automatic washing operations.
Tlhe drain tube 14 is inserted in a Vertical stand-pipe 16. The stand-pipe 16 is supported, for example, on a usual trap 18, which, in turn, is coupled to the drainage system 20 of the household.
During normal operation of the washing machine 10, and when the electric cord 12 is plugged into the usual electrical outlet, the washing machine proceeds with its washing operations, as explained above. However, in the event that the trap 18, or the ldrainage system 20, becomes plugged, the large amount of water used by the washing machine 10 quickly produces an overflow condition in the stand-pipe 16. .As mentioned above, the quantity of water which is caused to overflow from the stand-pipe when such a condition exists, is sufficient to roduce considerable ood damage to the dwelling in which the washing machine is used.
The present invention includes a control unit 22 which is mounted at a particular level on the stand-pipe 16. A mounting or clamping ring, or strap, 24 is axed to the housing of the unit 22, and this strap extends around the stand-pipe, as best shown in FIGURE 2. The clamping ring 24 is clamped tightly around the stand-pipe by means, for example, of a screw 26 which is threaded into the ends of the ring.
The housing of the control unit 22 includes a receptacle 25. The electric cord 12 for the washing machine 10, instead of being plugged directly in the electrical outlet 2S is plugged into the receptacle 26 of the control unit 22. The control unit, itself, has an energizing cord 30 which has a plug 31; the plug being plugged into the outlet 28.
The control unit 22 includes a pressure responsive electric switch 32. A tubular inlet member 34 is mounted on the housing of the control unit 22. This tubular inlet member 34 extends through an aperture in the stand-pipe 16 into the interior of the stand-pipe, as best shown in FlGURE 2. The pressure switch 32 is mounted adjacent the inner end of the inlet member 34, and the pressure switch includes a diaphragm which is actuated to actuate the switch, when the water pressure in the inlet member 34 is in excess of a particular predetermined pressure. An appropriate sea-ling gasket 35 is inserted between the inlet member 34 and the wall of the stand-pipe 16 to provide a pressure seal between the inlet member and the wall.
The pressure responsive electric switch 32 includes a pair of normally closed contacts 32u (FIGURE 3) which are caused to open when the pressure in the inlet tube 34 exceeds the predetermined pressure. The pressure switch may also include a pair of normally open contacts 32h which close when the pressure in the inlet tube 34 exceeds the predetermined pressure.
The electric energizing cord 30 may be a three lead type, and one of the leads is grounded by the circuitry of FIGURE 3. One of the remaining leads of the cord 30 is connected by the circuitry of FIGURE 3 to a terminal of the receptacle 26, and the other remaining lead is connected by the circuitry through the normally closed contact 32a to a second terminal of the receptacle 26. The receptacle 26 may include a third terminal which is grounded by the circuitry of FIGURE 3.
The leads of the cord 30 may also be connected to an electric alarm unit 38 by the circuitry of FIGURE 3, with the contacts 32h being in series circuit therewith. As mentioned above, the electrical cord 12 .of the washing machine is plugged into the receptacle 26.
Under normal operation of the washing machine of FIGURE l, the contacts 32a of the pressure responsive switch 32 are closed, and the contacts 3212 'are open. Therefore, the washing machine is energized through the ever, should a stoppage occuriin the drainage system, such that the water level in the stand-pipe 16 rises-above the level ofthe control unit 22, the resulting increase in Water pressure in the tubular member 34 causes the pressure responsive switch 32 to be actuated.
This actuation ofY the-pressure responsive switch 32 causes the contacts 32a to open. These contacts remain open so long as the stoppage condition exists, so as to de-energize the washing machine and its drainage pump. Should the stoppage condition correct itself, the contacts 32a will close automatically, and the washing machine will again be energized.
If so desired, the circuit of the alarm 38 m-ay be ineluded, so that the contacts 32h will close at the same time that the contacts 32a are open. This causes the alarm 38 to be actuated, so that the householder is made aware of the abnormal condition.
Y'Ihe invention provides, therefore, .a simple and inexpensive control unit. As mentioned above, the control unit mayY be easily installed in existing washer-standpipe combinations. When so installed, the control unit of the invention serves immediately to de-energize the washer, should a stoppage condition occur in the drainage system.
The -use of the present invention serves to prevent costly damage due to floods which often occur, when a stoppage condition in the drainage system arises. While a particular embodiment of the invention has been shown and described, modifications may be made, and it is intended in the claims to cover such modilications as tall within the spirit and scope of the invention.
