In the above-mentioned conventional configuration,
Foamed water containing air bubbles enables comfortable washing with a soft feeling. In addition, by mixing a large amount of air bubbles into the wash water, the flow rate of the wash water spouted from the spout can be significantly increased while spreading it moderately. It is possible to clean human body parts, and as a result, water and energy can be saved. Furthermore, since the instantaneous heating type heating means, which is energized only during use, is used for heating the cleaning water, it is possible to further save energy.

[0007] Also, since the heat retention control is performed by sitting down,
Since hot water at an appropriate temperature can be discharged from an early stage of use, the user does not feel uncomfortable. However, in such a configuration, the warmed water is discarded during the heat retention control, resulting in energy loss. In addition, since the hot water is removed in association with the seating, the hot water is removed even when the cleaning device is not used, for example, due to urine. As a result, the power consumption and the amount of water used have not largely changed from those using the hot water storage type heating means that does not mix air bubbles.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a configuration of a human body cleaning apparatus according to the present invention. FIG. 1 is a schematic diagram showing a supply system of cleaning water. In FIG. 1, reference numeral 1 denotes a constant flow valve,
A water supply pipe 2 is connected to the upstream side, and a solenoid valve 3 is connected to the downstream side. A heat exchanger 4 is connected downstream of the solenoid valve 3, and a vacuum breaker 5 is connected downstream thereof. The downstream of the vacuum breaker 5 branches in two directions, and one is a drainage pipe 6 for directly discharging excess water into the toilet.
The flow control switching valve 7 is provided on the other side. Flow control switching valve 7
Branch into two directions, one to the drainage channel 8 and the other to the flow path switching valve 9
Is connected. An air pump 10 is connected to the flow path switching valve 9 and is ejected from a selected flow path of the nozzle device 11. With this configuration, the washing water supplied from the water supply pipe 2 by the opening operation of the solenoid valve 1 is heated to a suitable temperature by the heat exchanger 4, pushes up the vacuum breaker 5, and the flow rate is adjusted by the flow control switching valve 7. The control valve 8 is reached. In the flow path switching valve 9, the air supplied from the air pump 10 flows into the washing water. Further, the washing water that has passed through the flow path switching valve 9 is jetted from the flow path selected by the flow path switching valve 9. As a result, the cleaning water spouted from the nozzle device 11 contains bubbles, so that a soft feeling can be obtained. In the present invention, a float switch 17 for detecting the water level in the heat exchanger 4 is provided, and when the predetermined water level is not detected by the float switch 17, the power supply by the electric heater is not performed, so that the empty cooking is performed. Can be prevented and safety can be improved.

FIG. 2 shows a time chart of the present invention. When the seat is detected by a seat switch (not shown) provided on the toilet seat (not shown) and a toilet lid open detection switch (not shown), the supply of the washing water is stopped by the solenoid valve 3 to the heat exchanger 4. Energize for a predetermined time. Here, the power supply time to the heating means can be changed according to the temperature detected by the water temperature detecting means 12 for detecting the temperature of the water flowing into the heat exchanger 4. Further, when the predetermined temperature is detected by the hot water temperature detecting means 13 for detecting the temperature of the hot water downstream of the heat exchanger 4, the energization is stopped, and when the hot water temperature detecting means 13 detects the predetermined temperature of −2 ° C. or less, re-energization is performed. The temperature of the hot water stored inside is kept constant. Since the inside of the piping can be replaced with the appropriate temperature water at the time of pre-cleaning, there is no fear of discomfort due to low temperature water and hot water coming out and causing burns. (Insulation control)

When a buttocks washing switch (not shown) is operated to start use, the air pump 1 is almost simultaneously operated with the solenoid valve 3.
0 is driven, and when the stable temperature is detected by the hot water temperature detecting means 13 downstream of the heat exchanger 4 or when a predetermined time has elapsed, the flow control switching valve 9 is moved from the pre-cleaning (self-cleaning) position to the drain passage 8.
Switch to. At this time, the water temperature detecting means 1 upstream of the heat exchanger 4
The time can be changed by 2 so that it can cope with the fluctuation of the incoming water temperature, and when the power saving switch is off,
Since the cleaning time at the pre-cleaning position can be delayed, there is no fear of discomfort due to low-temperature water coming out or burning due to high-temperature water coming out. Since the drainage position of the drainage channel 8 is set at a position where the nozzle can be washed, the nozzle cleaning effect is improved. (Pre-washing) When the flow control switching valve 9 is switched to the drainage path, the flow path switching valve 9 switches to the selected bottom flow path 14, bidet flow path 15, or soft flow path 16 at substantially the same time, and the nozzle is also selected. And the air pump 10 stops driving. (Nozzle extension)

When the nozzle has been extended to the selected position, the flow control switching valve 9 gradually raises the water pressure from the drainage channel 8 toward the water pressure setting position, and the air pump 10 is driven substantially simultaneously (soft start, Ass washing)

When a stop switch (not shown) is operated to stop use, the flow control switching valve 9 is switched from the water pressure setting position to the drainage channel 8, and the air pump 10 stops driving almost simultaneously, and the flow path is switched. The valve 9 is switched to the self-cleaning position and the nozzle is stored. (Nozzle storage). When the storage of the nozzle is completed, the flow control switching valve 9 is switched from the drainage channel 8 to the pre-cleaning (self-cleaning) position. The driving of the solenoid valve 3 is stopped after a predetermined time has elapsed. (Washing after nozzle)
After the washing is completed, the heat retention control is performed until the seat switch (not shown) and the toilet lid open detection switch (not shown) are turned off.
