[Function] When cleaning the bathtub, first open the drain valve to drain the remaining hot water, then spray water from the cleaning nozzle to wash out large debris (pre-wash), then close the drain valve and remove the cleaning agent. The cleaning agent is put into the bath from the tank and stored in the buffer. Next, water is poured into the bath, and this water is caused to flow into the buffer through the inflow port of the buffer lid, and mixed with a cleaning agent to prepare cleaning water. Next, the circulation pump is driven to suck the wash water from the circulation return pipe through the inlet of the circulation port cap,
It is pressurized and sprayed from the cleaning nozzle into the bath, and cleaning is performed by this spraying force and chemical force. The washing water circulates through the buffer → circulation port → return pipe → circulation pump → outflow pipe → washing nozzle → bath tub → buffer. The cleaning water is heated by the heater during this circulation (in the automatic cleaning device).

After washing for a certain period of time, the drive of the circulation pump is stopped, the drain valve is opened to drain the wash water, the drain valve is closed, tap water is stored in the buffer, and the circulation pump is driven again. The washing water in the bathtub and the circulation system is washed away, then the drain valve is opened and tap water is sprayed directly from the washing nozzle into the bathtub to perform the final rinsing.

The wash water circulates in the order of buffer 3 → circulation port 4 → return pipe 6 → circulation pump 14 → going pipe 8 → wash nozzle a → bath 1 → buffer 3. The cleaning water is heated by the heating device 17 during this circulation (in the automatic cleaning device).

After washing for a certain time, the circulation pump 14
Drive is stopped, the drain valve 5a is opened to drain the wash water, then the drain valve 5a is closed, and tap water is supplied from the water supply pipe 9 to the buffer 3
The circulation valve 6a is stored inside, the circulation pump 14 is driven again to wash away the washing water (detergent) in the bath 1 and the circulation system, and then the drain valve 5a is opened to tap water from the washing nozzle a. It is sprayed into the bathtub 1 to perform a final rinse.

In the above-mentioned operation, the wash water flowing from the bath 1 into the buffer 3 is once squeezed by the slit 11 of the buffer lid 10 and further flows into the wall surface of the buffer 3 as such, and further the slit of the cap 12 is inserted. After being squeezed by 13, it is sucked into the circulation port 4. Therefore, the inclusion of air is prevented.

[0019]

The effects of the buffer device according to the present invention are as follows.

A. A buffer was formed on the bottom of the bath, and a buffer lid with a slit was attached to the buffer, and a cap with a slit was attached to the circulation port, so a small amount of circulating water (wash water) was created by the action of this buffer lid and cap.
There is no air entrapment even when circulating. Therefore, since the circulation pump does not stop functioning, cleaning can be performed using the minimum amount of cleaning water, and the amount of cleaning agent used and heating energy can be saved.

B. Since the lid with the slit is attached to the buffer, the bottom surface in the bathtub is flat and looks good, and the slit is formed small so that large dust can be removed by the slit. As a result, dust does not enter the buffer, and the dust is prevented from entering the slit of the cap of the drain port doubly. Therefore, there is no fear of causing a circulation failure even if the strainer is not attached.
