The outer hose 51-A is connected to an introduction hose 55 of the main body 54, and the introduction hose 55 reaches the bottom surface of the main body 54. In addition, the inner hose 51-B is connected to the washing tub 5 through the water supply valve 53.

The water supply hose has a double structure and lacks flexibility, making it time-consuming to install the main unit and connect the water tap. Next, it may take a long time in proportion to the slack in the water supply hose until a crack occurs in the inner hose and the water supply valve on the water supply side stops, and a large amount of leakage water is required. However, when the amount of water leaking is small, water may evaporate even if it reaches the bottom of the main unit, resulting in cracks in the water supply hose not being noticed and water being wasted. In addition, if the leaking water that has accumulated between the outer hose and the inner hose freezes, the expansion pressure will cause cracks in the outer hose, causing the leaking water to drip from the outer hose onto the floor, staining the floor. However, if it continued for a long period of time, it would have caused water damage to the house. Furthermore, when replacing the water supply hose, the water that had accumulated between the inner and outer hoses would overflow due to the location of the water tap and the main unit, staining the floor near the main unit.

If there is an abnormality, the predetermined water pressure will not be obtained. This difference is detected and input to the control circuit, and if it is normal, the water supply valve on the main body side is operated, and when it is determined that there is an abnormality, the water supply valve on the water supply side is stopped. In the second method, the outputs of the flow rate sensor installed near the water supply valve on the water supply side and the flow rate sensor installed inside the main body are monitored by a control circuit, and normally the same output is obtained, but when an abnormality occurs, the output is There is a difference between This is used to operate the water supply valve on the water supply side. In the third method,
A sheet switch made up of two thin films facing the outside of the water supply hose is wrapped around it. Normally, the thin films do not come into contact with each other, but in the event of an abnormality, the water pressure from the cracks presses on the sheet switch, causing internal damage. The opposing electrodes of the two are in contact with each other. The control circuit stops the water supply valve when the counter electrodes make contact.

Further, a water pressure sensor 5 is provided near the input side of the water supply valve 3. The water pressure sensor 5 passes a thin tube into the water supply hose 1 to cause a diaphragm (not shown) inside the water pressure sensor 5 to vary in water pressure, and converts the amount of variation into an electrical signal. The control circuit 6 inputs the output of the water pressure sensor 5 and controls the water supply valve 2.
, the water supply valve 3 is being operated.

First, the water supply valves 2 and 3 are stopped, and then the water supply valve 2 is activated. Next, the control circuit 6 inputs information from the water pressure sensor 5, and operates the water supply valve 3 if the pressure is above a predetermined value. When the water supply hose 1 cracks, the water pressure inside the water supply hose 1 decreases, so the output value of the water pressure sensor 5 decreases, and the control circuit 6 determines that the water pressure is below a predetermined value and immediately stops the water supply valve 2. It is something that makes you

First, the water supply valve 2 is stopped, and then the water supply valve 2 is activated. This control circuit 6 compares the output values of the flow rate sensors 7 and 8. If normal, the comparison value between flow rate sensor 7 and flow rate sensor 8 is 0.
Therefore, the water supply valve 2 continues to operate as it is, but if there is an abnormality, water will flow out from the crack, so the output value of the flow rate sensor 8 will be lower than that of the flow rate sensor 7. Control circuit 6
Since the comparison value between the flow rate sensor 7 and the flow rate sensor 8 is no longer 0, this is detected and the water supply valve 2 is stopped.

The opposing electrodes 10 of the sheet switch 9 are input to the control circuit 6, and detection is performed by contacting or non-contacting the opposing electrodes 10 with each other. A thin film electrode 10 and a rubber sheet 12 form a sandwich structure on both sides of a grid-like insulator 11. When pressure is applied to the sheet switch 9, the counter electrode 10 contacts in the space of the insulator 11 and conducts.
