Abstract

PURPOSE:To facilitate construction and to widen a set adjustment range by detecting the water level in a bathtub by a pressure sensor outside the bath room. CONSTITUTION:When automatic hot-water supply is commanded, a solenoid valve 17 for automatic hot-water supply and a solenoid valve 22 are opened, a pump 7 is started, and a solenoid valve 8 is opened. Hot water supplied form the hot-water supply circuit B consisting of an inhalant siphon 13, a heat exchanger 2 for hot-water supply, a hopper 16, etc., reaches the bathtub 4 through a by-pass pipe 10 and a return pipe 6 and the path from the pressure sensor 9 to the bathtub 4 is purged with air. The valve 8 is closed a constant time later and the hot water flows in the bathtub 4 from an onward pipe 5; and a comparator is powered no to compare the output value of the sensor 9 based upon the water level i the bathtub with a partial pressure value set with a bathtub water level variation switch 27 by using the pipes 6 and 10 as pressure-detected pipes. When the both coincides with each other, the hot water supply is stopped with a signal from the comparator.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bathtub water level setting device for automatically stopping water supply (hot water) to a bathtub, such as an automatic bathtub.

(Prior Art and Problems) Conventionally, in a device that automatically stops pouring hot water or water into a bathtub at a set water level, the detection of the bathtub water level is based on the water level as shown in Utility Model Application No. 169937/1983. This was done by installing a detector in the bathtub.

However, since the set water level was adjusted by changing the spring pressure using a screw, the range of adjustment was limited. For example, the difference in water level from the water level detector to the set water level is as much as 200 mm between a Japanese bus and a Western bus, and in order to satisfy this difference, there are issues such as spring characteristics and increasing the diameter of the diaphragm. It was difficult to install it in a dovetail bathtub. Furthermore, since the water level detector is attached to the bathtub, it is necessary to install a detection cord, and care must be taken to avoid water leakage or breakage of the cord, which is also troublesome.

The present invention eliminates the above-mentioned conventional drawbacks, and aims to provide a bathtub water level setting device that can detect the water level outside the bathroom and easily adjust the set water level over a wide range.

In the embodiment having the above configuration, a test run is performed upon completion of construction, and the automatic hot water supply stop water level is set. First, hot water is supplied to the bathtub (4), and when the water level reaches the lowest water level (Image N) at which bathing is possible, the hot water supply is temporarily stopped. Set the changeover contact of the changeover switch (31) to the setting/memory circuit (35) side. The slide switch (2C+a) creates a voltage corresponding to the connected contacts in stages, and the volume (29
In b), the voltage of one step width is made variable. Since these two voltages are added by the adder (36), the setting circuit (36)
The output of step 5) is as shown in Figure 3. Now the pressure sensor (9
), the second operational amplifier (40) has a high value, cutting off the second transistor (44), and the LED (32) is at 0FFL/. Operate the slide switch (29a) and volume (29b) to increase the set voltage. When the output voltage of the pressure sensor (9) and the set normal pressure become close, the second operational amplifier (40
) becomes low and exceeds the shift voltage of the Zener diode (43), causing the second transistor (44) to conduct. - The power tube 1 operational amplifier (39) changes from a low value to a high value, but the first transistor (42) is conductive until it exceeds the shift voltage of the Zener diode (41), and in this state, the transistor (48) is always connected to the base. Current is flowing and the LED (32) lights up. When the set voltage is further increased, the first operational amplifier (39) becomes high and cuts off the N1 transistor (42). Then the transistor (
The base current to 48) is intermittently passed by the oscillation circuit (5), causing the LED to blink. Therefore the LED
Adjust the set voltage while watching the display status of (32), turn the slide switch (29m) and the volume (29m) at the lit position.
9b) and maintain that state. Next, the full water level (L
MAX), turn the selector switch (31),
Perform the same operation as above to set the full water level. The setting values set in this way are stored on the slide switch (29a
) (30a) and volume (29b) (30b
) is stored as the resistance value.

In this way, the lowest water level (1, MIN) and the full water level (LMAX) are set and stored during the test run, and the value obtained by dividing this open setting voltage using the bathtub water level change switch (27) is determined by the comparator (49). It is compared with the output value of the pressure sensor (9), and when the two match, the hot water supply is stopped by a signal from the comparator (49). Therefore, the minimum water level (LMIN) is set by the bathtub water level change switch (27).
Hot water supply can be stopped at a desired water level within the range from 1 to the full water level (LMAX).

It is compared with the minute and hour values written by Itsuki (2) 1. In this way, from the outgoing pipe (5) to the bathtub (4)
) while supplying hot water, the output value of the pressure sensor (9) is compared with the above partial pressure value, and if the two match, the hot water supply is stopped by a signal from the comparator (49).

Here, the return pipe (6) and bypass pipe (10) are first air purged, but depending on the positional relationship between the bathtub (4) and the main body (1) and the piping configuration, the water level in the bathtub (4) may be lower than the bathtub. There is a possibility that air has entered by air displacement before reaching the water level (LBA) of the adapter (24), and even after flushing hot water and air purging, the comparator (49) does not send a signal to stop the hot water supply. If it is, the automatic hot water supply will end.
