Abstract

A hot water extraction system including a water tank having means for connection to a container containing a vacuum motor and to a water extractor and a hot water applicator, the applicator having a connection for attachment to a normal faucet, a hose from the faucet passing through a chemical cleaning solution, and a valve for the emission of a predetermined amount of the water including the solution, the vacuum created by the vacuum motor in the container creating a vacuum in the water tank and thereby providing suction through a hose leading to the water extractor whereby the hot water containing the solution which has been emitted on to a surface such as a rug by the applicator is drawn into the water tank where it is accumulated until the cleansing is completed. There are deflecting means in the water tank whereby the vacuum from the vacuum container draws air from the water tank in one direction while the entry of the water from the extractor is drawn into the tank from another direction so that the said water does not enter the line leading to the vacuum motor. The tank may be so arranged as to be carried on a conventional vacuum canister and is detachable and storable when the apparatus is not being used as a hot water extraction system.

Claims

1. A hot water extraction system comprising a vacuum container;

a water tank for normally containing water up to a selective maximum operative water level therein under a vacuum condition and including a first hose interconnected to said vacuum container whereby a vacuum condition in the vacuum container provides a corresponding vacuum condition in the water tank;

a water extractor including a second hose interconnected to said water tank whereby a vacuum condition in said water tank provides a corresponding vacuum condition in said water extractor;

stationary flow direction controlling means stationarily fixedly disposed relative to the selective maximum operative water level in the water tank for preventing the water flowing into the water tank from the extractor up to such maximum water level under a vacuum condition from entering the vacuum container, said means being arranged relative to the extending disposition of such water level for controlling the flow direction of the vacuum induced flow into and through the water tank to travel substantially at inclined angles to such extending disposition of the water level;

a water applicator in proximity to said water extractor;

a line for the supply of water comprising a hose adapted to interconnect said water applicator to a conventional remote source of hot water supply; and

a valve for metering the amount of water supplied through said water applicator.

2. The hot water extraction system of claim 1 including a container for dispensing cleansing chemicals disposed in the said line leading from the conventional water supply to the water applicator.

3. The hot water extraction system of claim 1 in which the means for preventing water flowing into the water tank from the extractor from entering the vacuum container comprises deflecting means.

4. The hot water extraction system of claim 3 in which said deflecting means comprise

first deflecting means in operative coacting arrangement with said first hose for deflecting in a predetermined direction the flow of air from the water tank to the vacuum container;

and

second deflecting means in operative coacting arrangement with said second hose for deflecting in a predetermined direction the incoming flow of air and water from the extractor into the water tank.

5. The hot water extraction system of claim 4 in which the first and second deflecting means are remotely disposed in indirect operative flow relation with respect to each other.

6. The hot water extraction system of claim 1 in which the means for preventing water flowing into the water tank from the extractor from entering the vacuum container comprise

stationary inlet flow directing means in operative coacting arrangement with said second hose stationarily fixedly disposed at a level spaced relatively remotely above the selective maximum operative water level in the water tank for directing the incoming flow of air and water from the extractor into the water tank along an increasingly expanding and diverging initial fluid velocity deceleration flow path initially relatively remote from the operative level of the water in the water tank to enhance the differential flow velocity between the initially incoming flowing air and water and in turn separation of the water from the flowing air while substantially avoiding disturbance of such level of water;

and

stationary outlet flow directing means in operative coacting arrangement with said first hose spatially remote from the inlet flow directing means and stationarily fixedly disposed at a level substantially correspondingly spaced relatively remotely above such maximum water level for directing the outgoing flow of air from the water tank to the vacuum container along a terminal fluid velocity acceleration flow path relatively remote from said initial fluid velocity deceleration flow path and from such level of water to enhance removal of such air from the water tank while substantially avoiding both entrainment of water into such air and disturbance of such level of water.

7. The hot water extraction system of claim 6 in which the inlet flow directing means and outlet flow directing means are remotely disposed in indirect operative flow relation with respect to each other.
