Abstract
An overflow control unit for a washing machine which interconnects the drain hose of the washing machine to a stand-pipe is provided which comprises a cylindrical plug device having a central axially extending passageway therethrough and a by-pass valve interconnecting the passageway of the cylindrical plug with the atmosphere, the by-pass valve having an open and a closed position. In one embodiment the overflow control unit is operatively connected to a pressure switch so that upon a build-up of water pressure within the stand-pipe due to the drain being obstructed the switch is activated to break the electrical circuit to the washing machine.
Claims15
An overflow control valve for connecting a washing machine drain hose to a stand-pipe comprising:
- a. cylindrical plug means having a central axially extending passageway therethrough, one end of said plug means being connected to the upwardly extending end portion of the stand-pipe, the other end of said plug means being connected to the drain hose of the washing machine;
- and,
- b. by-pass valve means positioned within a sidewall of said cylindrical plug means, said by-pass valve means having an open position for connecting said axially extending passageway with the atmosphere when said washing machine is not in a drain cycle and a closed position when said washing machine is in a drain cycle.
A washing machine overflow control unit for connecting a washing machine drain hose to a stand-pipe comprising:
- a. a wall mounted outlet box having a drain therein, said drain being connected to and in fluid communication with the stand-pipe;
- b. a cylindrical plug means having a central axially extending passageway therethrough, said plug means being positioned within the said box and having an upwardly extending end portion connected to the drain hose of said washing machine, said plug means further being provided with by-pass valve means in the side wall thereof having an open position for connecting said passageway with the atmosphere when said washing machine is not in a drain cycle and having a closed position when said washing machine is in a drain cycle;
- c. pressure sensing means operably connected to said plug means and in fluid communication with said central axially extending passageway;
- d. a power circuit including a normally closed switch means connected to said sensing means and adapted to be opened when pressure in said passageway extends above a given level;
- and
- e. socket means operably connected through said switch means to said power circuit to apply power to said washing machine when said switch means is closed.
In a washing machine overflow control unit for connecting a washing machine drain hose to a stand-pipe wherein said unit is provided with a pressure sensing means operatively connected to a control means for deactivating the washing machine when a pressure build-up is detected within the drainage system, the improvement being a control valve means comprising a cylindrical plug means having a first central extending passageway therethrough, one end of said cylindrical plug means being connected in a fluid-tight relationship, to the upwardly extending end portion of said stand-pipe, the other end of said cylindrical plug means being connected in a fluid-tight relatinship, to the drain hose of the washing machine;
- by-pass valve means positioned within a side wall of said cylindrical plug means, said by-pass valve means having an open position for connecting said first central axially extending passageway of said cylindrical plug means with the atmosphere when said washing machine is not in a drain cycle and a closed position when said washing machine is in a drain cycle;
- a second passageway transversely disposed within the side wall portion of said cylindrical plug means and intersecting said first central axially extending passageway;
- and, conduit means sealably connected at one end thereof to said second passageway and sealably connected at its other end to said pressure sensing means to provide fluid communication between the first central axially extending passageway of said cylindrical plug means and said pressure sensing means.
