Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a washing machine pan.

(Prior art) When placing a washing machine in a place with water supply and drainage facilities such as a washroom, in order to protect the floor from the washing water splashing from the washing machine, the washing machine may be placed on the washing machine pan. is there. Such a washing machine pan is provided with a drain pipe for flowing the drainage from the washing machine, and the peripheral edge of the pan is erected.

(Problems to be solved by the device) However, when the drainage pipe is clogged with dust such as lint generated during washing, the water level in the washing pan rises due to the drainage from the washing machine and overflows from the outer peripheral portion. It may run out onto the floor and cause corrosion.

(Means for Solving the Problems) In order to solve the above problems, in the washing machine pan of the present invention, one side portion of the outer peripheral portion 5 is folded back inward to form a folded portion 17, and the folded portion 17 is washed. A sensor 19 that detects a rise in water level when the drainage port 15 of the machine pan is clogged is provided, and a valve 27 that supplies water to the washing machine 7 by a signal from the sensor 19
I tried to close.

(Operation) According to the above means, when the drainage pipe is clogged, when the water level rises above the predetermined height in the washing machine pan, the sensor provided inside the folded portion of the outer peripheral portion detects this and the valve Send a signal to stop the water supply to the washing machine.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of a washing machine pan of the present invention.

The washing machine pan 1 includes a floor 3 having a rectangular shape in a plan view and an edge 5 standing on the outer periphery of the floor 3. A washing machine 7 is placed on the floor 3, and the washing machine 7 receives water from the water tap 9 directly or via a hose 11. The laundry drainage discharged from the washing machine 7 is drained from a drainage port 15 provided in the floor section 3 through a bellows-shaped hose 13 attached to the washing machine 7.

The edge portion 5 has one side portion folded back inward to form a folded portion 17. The folding | returning part 17 is provided with the space | interval with the floor part 3 as shown in FIG.

The inner wall surface 17a of the edge portion 5 is protected by the folded portion 17.
A sensor 19 is provided to detect the presence of water.

The sensor 19 consists of two sensors, 19a and 19b, one above the other,
Drainage outlet such as lint contained in the drainage of the washing machine 7
When the inside of the washing machine pan 15 is clogged and the water level in the washing machine pan 1 rises, first, as shown in FIG. 1, the controller 21 is activated by the signal from the lower sensor 19a and the bell 23 is rung. When the water level further rises and reaches the upper sensor 19b, the wiring for water supply leading to the water tap 9 by the operation of the controller 21.
The electromagnetic valve 27 provided at 25 is closed to stop the water supply to the washing machine 7.

Reference numeral 29 is a breeze hole provided in the upper portion 17a of the folded portion 17 for venting air.

FIG. 3 shows another embodiment of the washing machine pan of the present invention. The same parts as those in the above embodiment are designated by the same reference numerals and the description thereof will be omitted.

This sensor 19 is provided on the upper portion 17a of the folded portion,
The float switch 31 slidable in the vertical direction activates when the water level reaches a predetermined height.

(Effect of the Invention) As described in detail above, according to the present invention, when the drainage pipe is clogged and the water level in the washing machine pan rises, the sensor works to stop the water supply to the washing machine, so that the water overflows. There is no risk of getting the floor wet, and water leakage damage can be prevented in advance.

Since the sensor is provided in the folding part, it is protected from the outside, so it is not easily damaged, and the presence of this folding part prevents waves from forming inside the folding part, so the detection by the sensor is characteristic. Become. Furthermore, since the opening for venting air is provided in the folded-back portion, air is not accumulated, and in this respect also, the detection by the sensor becomes accurate.
