Description

[Detailed description of the invention] The present invention relates to a washing machine that adjusts the water level in the tank by adjusting the height of the drain port of the hose, and in particular, the water level in the tank can be set steplessly and extremely easily. The present invention also relates to a washing machine in which the water supply to the tank can be automatically stopped.

In a conventional washing machine of this type, as shown in Fig. 1, a knob 3 for adjusting the height of an overflow port 2 of a bellows-like extendable overflow hose 1 is attached to an overflow filter 4, and the height can be adjusted as shown by arrow a. The height of the overflow port 2 of the overflow hose 1 is adjusted steplessly using the knob 3, thereby steplessly adjusting the water level in the tub (washing tub).

If the configuration is as above, the overflow port 2 of the overflow hose 1 can be connected with the knob 3.
The water level in the tank is set to a predetermined level by steplessly adjusting the height of the water tank, and the user must close the water faucet when the water overflows from the overflow port 2 of the overflow hose 1. However, the closing operation was troublesome, and if left open, water was wasted.

The present invention relates to a washing machine that eliminates the above-mentioned drawbacks.

An embodiment of the washing machine of the present invention will be described below with reference to FIGS. 2 to 4.

In the washing machine of the present invention, a knob 13 for adjusting the height of an overflow port 12 of a bellows-like expandable overflow hose 11 is attached to an overflow filter 1.
4, the height of which is adjustable as shown by arrow a', and the knob 13 is provided with a switch portion 15 consisting of a reed switch or the like.
A float 18 having a magnet 17 for operating the switch portion 15 of the float switch 16 is arranged so as to be guided by the overflow hose 11 and move up and down according to the rise and fall of the water level, The switch part 1 is connected to the switch part 15 of the float switch 16.
5 is opened by the magnet 17 of the float 18, the electricity is stopped and the water supply is stopped (water cutoff).
It is constructed by connecting a water supply valve 19 to the water supply valve 19.

In the above configuration, the power supply 20, the switch part 15 of the float switch 16, and the water supply valve 19 are connected as shown in the circuit diagram shown in FIG. 4, and in FIG. 4, 21 is a select switch, 22 is a washing timer, and 23 is a motor.

Next, to explain the water level adjustment state of the washing machine configured as described above, the water level in the tub is adjusted to a predetermined water level by steplessly adjusting the height of the overflow port 12 of the overflow hose 11 using the knob 13. When the select switch 21 is set to the water supply position, the water supply valve 19 is opened and water is supplied.
When the water level in the tank reaches a predetermined water level, the float 18 rises to a predetermined water level (floats up) and comes into contact with the float switch 16, and the magnet 17 of the float 18 causes the float switch 1 to be
The switch portion 15 of No. 6 is opened to stop the power supply to the water supply valve 19, and the water supply is stopped by the water supply valve 19 to set the water level in the tank to a predetermined water level.

Since the washing machine of the present invention has the above-mentioned configuration, the water level in the tub can be set steplessly, extremely easily, and reliably, and the water supply to the tub can be automatically shut off. .
