を終了する。A first embodiment of the present invention using the water level detecting means 3 having the above structure will be described with reference to the flowchart of FIG. First, when the control means 5 is set by the input means 1 to supply the bath water into the tank using the water supply pump 12, the control means 5 sends a signal to the water supply pump driving means 4 in step 500 to cause the water supply pump 12 to operate. Turn on. Next, in order to proceed to the following sequence only when the water level in the tank 28 changes and the output frequency of the water level detecting means 3 changes, step 50
At 1 and step 502, it is determined whether the water level in the tank 28 is equal to or higher than the water level reference plane of FIG. 7 at every constant time Ta (for example, 1 second). After clearing, in step 504, the water level detection means 3
The output frequency of is measured and this value is set to 0 . Step 50
After a delay of T b (eg 5 seconds) at 5, step 506
Then, the output frequency is measured again and this value is set to N. In step 507, it is determined whether or not the set water level set by the input means 1 or the like has been reached, and if the set water level has been reached, step
At 517, a signal is sent to the water supply pump driving means 4 to turn off the water supply pump 12 to end the water supply operation. If the set water level has not been reached, go to step 508 and set 0-
N and a are compared, and if 0 − N ≦ a , step
From 509 to step 510, it is judged whether or not the predetermined number of cycles is reached after incrementing the number of cycles N, and if N has reached the predetermined number of cycles, the amount of water supply by the water supply pump 12 has decreased. That is, it detects that the bath water is almost exhausted, and goes from step 511 to step 512 to turn off the water supply pump 12 and turn on the water supply valve 14.
Turns on and automatically switches from bath water supply to tap water supply. Where a is the frequency corresponding to when the water level changes little in the tank 28 between the predetermined time T b. If the predetermined number of cycles is 0 - N ≤ a , the water supply is switched to the immediate water supply valve, and may be set to 4 or 8 in consideration of the influence of external noise. Meanwhile in step 508
0 - N> If a, also if no N in step 510 reaches the predetermined number of cycles, N in step 516
The value of is substituted for 0 and the process returns to step 505. Step 5
Below 03, tap water is supplied by the water supply valve 14 for a certain period of time Ta
Each time, it is determined whether the water level in the tank 28 has reached the set water level, and when it reaches the set water level, the water supply valve 14 is turned off and the water supply operation is ended.

When it is set to supply the bath water into the tank by using the water supply pump 12, the signal is sent to the water supply pump driving means 4 in step 520 to turn on the water supply pump 12. Next, in order to proceed to the following sequence only when the water level in the tank 28 changes and the output frequency of the water level detecting means 3 changes, a delay of a constant time T c (for example, 10 seconds) is provided in step 521. Here, T c is the tank that is supplied by the water supply pump 12 or the water supply valve 14 when it is smaller than the normal water supply.
It is the time from when there is no water in 28 until it reaches the water level reference plane. Since the following steps 522 to 536 are the same as the contents of steps 503 to 517 of the first embodiment, description thereof will be omitted.

Furthermore, the displacement detection unit for water level detection uses a variable inductance method that converts changes in pressure proportional to the water level into changes in the inductance of the coil, which converts changes in pressure proportional to the water level into changes in the capacitance of the capacitor. The same effect can be obtained even if the output signal is connected to the oscillation circuit as the water level detecting means as the variable capacitance method.

In addition, the water supply can be switched in a short time, the washing time can be shortened and the pump can be prevented from idling, which greatly contributes to the efficiency of washing work and the durability of the pump.
