Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a human body cleaning apparatus according to an embodiment of the present invention. Here, FIG. 1 is a schematic configuration diagram showing a supply system of cleaning water. In FIG. 1, a constant flow valve 12 and a solenoid valve 1
3. The heat exchanger 14 is connected. A vacuum breaker 15 is connected to an outlet of the heat exchanger 14.
The downstream of the vacuum breaker 15 branches in two directions, one of which is to a drainage pipe 16 for directly discharging excess water into the toilet.
The other is connected to the pulsation generator 17. Downstream of the pulsation generator 17, a flow path switching and flow control valve 18 is connected. The downstream side of the flow path switching and flow control valve 18 branches in two directions, one of which is connected to a drainage path 19, and the other of which is connected to a nozzle device 21 through a flow path switching valve 20 for jetting washing water to a human body. In this example, the flow path switching valve 20 is integrally formed in the nozzle device 21.

A hot water heater 22 is provided in the heat exchanger 14.
However, a cold water thermistor 23 and a hot water thermistor 24 are provided at the water inlet and the water outlet of the heat exchanger 14, respectively. The drainage of the drainage channel 19 is located at a position where the body of the nozzle device 21 can be washed. In addition, the nozzle device 21
Has a buttocks channel 25, a soft channel 26, a bidet channel 2
7 are formed. The control of each section is performed by the controller 28.

In this embodiment, an accumulator 29 is provided upstream of the pulsation generator 17, a float switch 30 is provided in the heat exchanger 14, and a temperature fuse 31 is provided in the pulsation generator 17. The accumulator 29 is for preventing the pulsation generated by the pulsation generating device 17 from propagating upstream, and the float switch 30 does not energize the hot water heater 22 when the predetermined water level is not detected. By doing so, the boil-off is prevented, and the temperature fuse 31 stops the drive when the pulsation generator 17 rises to an abnormal temperature, thereby ensuring safety.

With the above configuration, the washing water supplied from the water supply pipe 11 by the opening operation of the solenoid valve 13 is supplied to the heat exchanger 1.
4 is heated to a suitable temperature hot water and the vacuum breaker 15
Pulsation is given by the pulsation generator 17,
The flow reaches the flow path switching and flow control valve 18. Here the washing water is
The flow rate is adjusted by the flow path switching and flow control valve 18, reaches the flow path switching valve 20, passes through the flow path selected by the flow path switching valve 20, and is ejected from the nozzle device 21.

FIG. 2 shows a time chart of the present invention. When seating is detected by a seating switch (not shown) provided on a toilet seat (not shown), the flow of washing water starts by opening the solenoid valve 13 and the hot water heater 22 in the heat exchanger 14 is started. . When the hot water thermistor 24 provided at the water outlet of the heat exchanger 14 detects a predetermined temperature, the output of the hot water heater 22 is lowered, the electromagnetic valve 13 is closed, and the flow of washing water is stopped. As a result, the water retained in the heat exchanger 14 is replaced with hot water at a predetermined temperature. The washing water supplied during this operation is discharged from the drainage passage 19 selected by the flow path switching and flow control valve 18 and discharged into the toilet.
At this time, by setting the drainage of the drainage channel 19 to a position where the body of the nozzle device 21 can be washed, the nozzle device 21 can be cleaned.
Body cleaning can be performed. A series of these operations are controlled by the controller 28. In addition to the hot water thermistor 24 provided at the outlet of the heat exchanger 14, the heat exchanger 14
If the cold water thermistor 23 is provided in the water inlet section to detect the incoming water temperature, the control of the hot water thermistor 24 can be performed more effectively. (Water-flow heating) As described above, the output of the hot water heater 22 is lowered after stopping the flow of the cleaning water. At this time, the temperature of the cleaning water stored in the heat exchanger 14 always includes a predetermined temperature. The controller 28 controls the output of the hot water heater 22 based on the signal from the hot water thermistor 24 so that the temperature is maintained within the predetermined temperature zone. For example, the predetermined temperature is 40 ° C. and the predetermined temperature zone is 3
When the temperature is set to 8 ° C. to 42 ° C., the temperature of the washing water in the heat exchanger 14 is controlled so as to always fall within this range. With this heat retention control, there is no need to worry about low-temperature water coming out when washing the human body and feeling uncomfortable, or hot water coming out and causing burns. It should be noted that this heat retention control cannot be performed on the retained water in the piping downstream of the heat exchanger 14, but there is no practical problem since the retained water is discharged during the pre-cleaning described later and replaced with hot water of an appropriate temperature. . (Heat Insulation Control) Next, when a posterior switch (not shown) is operated to start the posterior cleaning, the electromagnetic valve 13 and the hot water heater 2 are operated.
2. The pulsation generators 17 are sequentially activated. These activations are performed in conjunction with the operation of the posterior switch. However, it is of course possible to set each of them to be activated after a predetermined time delay after the operation of the posterior switch. Here, the flow path switching and flow control valve 18 has been previously switched to a flow path toward the nozzle device 21 and the downstream flow path switching valve 20 is set to the self-cleaning (SC) position. Water is spouted from the spout of the nozzle device 21. That is, pre-washing of the spout is performed. Note that the self-cleaning position referred to here includes the buttocks channel 25, the soft channel 26, and the bidet channel 2.
7 shows a state in which all three flow paths are opened. At this time,
Since the pre-washing is performed with the pulsating washing water, dirt on the spout can be effectively washed off. (Pre-cleaning) After pre-cleaning has been performed for a predetermined time, the flow path switching and flow control valve 1
By 8, the flow path of the washing water is switched to the drainage path 19. The drainage destination of the drainage channel 19 is the nozzle device 21 as described above.
The nozzle body 2 is located at a position where the body of the
1 body cleaning can be performed. Here, since the body cleaning of the nozzle is performed with pulsating cleaning water at an appropriate temperature, dirt can be effectively removed. Then, the nozzle extends from the storage position to the buttocks washing position, and the flow path switching valve 20 switches to the buttocks flow path 25. (Nozzle extension) Also, before cleaning the body of the nozzle device 21, the cleaning water is heated by the hot water heater 22 until the temperature becomes suitable for sterilization, and the hot water is discharged. It is possible to carry out not only washing but also sterilization, which is very hygienic. If the time when the flow path switching valve 20 is switched to the posterior flow path 25 is set to be after the hot water thermistor 24 detects a hot water temperature suitable for washing the human body, hot water is discharged from the nozzle and burns. Can be prevented.

When the extension of the nozzle to the buttocks washing position is completed, the electromagnetic valve 13 is closed for a short time, and the flow path of the washing water is switched from the drainage path 19 by the flow path switching and flow control valve 18 to the nozzle device 2.
The flow is switched to the first side and the flow rate is gradually increased toward the set water force, and the solenoid valve 13 is opened again during the operation. Thus, even when the set water force is strong, the water is gradually changed from the soft water discharge to the set water force, so that the user does not feel uncomfortable. (Soft Start) The above is an example of the soft start by the flow path switching and flow control valve 18, but the soft start can also be performed by using the pulsation generator 17. For example, at the start of cleaning, high-frequency pulsation is given to the cleaning water, and the frequency is gradually lowered, so that the cleaning intensity can be gradually increased even at the same flow rate. Of course, in order to continuously increase the cleaning intensity, both the flow path switching and flow rate adjusting valve 18 and the pulsation generator 17 may be controlled in a combined manner.

When the soft start operation is completed, the posterior washing is performed with the set hot water of the appropriate temperature. Also in this case, the pulsation is given to the washing water by the function of the pulsation generator 17, so that the washing can be comfortably performed even with a small amount of water. Next, when a stop switch (not shown) is operated to stop the posterior washing, the pulsation generator 17 stops driving, and the flow of the washing water is switched by the flow path switching and flow rate adjusting valve 18. The road is switched to the drainage channel 19. At this time, the body cleaning of the nozzle device 21 can be performed as in the case of the nozzle extension. Then, the nozzle retracts and is stored in the storage position. Note that the flow path switching valve 20 is switched to the self-cleaning position. (Nozzle Storage) When the storage of the nozzles is completed, the flow path of the washing water is switched again to the nozzle device 21 side by the flow path switching and flow control valve 18, and the pulsation generator 17 is also activated. Here, the flow path switching valve 20 is set at the self-cleaning position, and the cleaning water is discharged from the water discharge port of the nozzle device 21.
That is, post-washing of the water outlet is performed. At this time, the post-washing is performed with the pulsating washing water, so that the dirt on the water discharge port can be effectively washed off. (Post-cleaning) During a series of operations from the above-described pre-cleaning to post-cleaning, the controller 28 controls the hot water thermistor 24 and the cold water thermistor 23.
Is controlled based on the signal from the heat exchanger so that the washing water flowing out of the heat exchanger 14 is maintained at an appropriate temperature.

After the post-washing has been performed for a predetermined time, the pulsation generator 17 and the solenoid valve 13 stop driving in order, and the hot water heater 2
2 lowers the output. Also here, the heat retention control is performed so that the temperature of the washing water stored in the heat exchanger 14 is always kept within a predetermined temperature zone including a predetermined temperature. This is to prevent the discharge of low-temperature water or high-temperature water even when the cleaning operation is performed again. (Heat Insulation Control) When the seating switch (not shown) detects the unseating (seating off), the driving of the hot water heater 22 is stopped. However, in order to prevent the washing water in the heat exchanger 14 from freezing, when the cold water thermistor 23 or the hot water thermistor 24 detects the water temperature at which there is a possibility of freezing, the hot water heater 22 is driven for a predetermined time to remove the washing water. Perform warming control. (Standby) By the way, in this embodiment, the case where the buttocks switch is operated has been described. However, a bidet switch for starting bidet washing or a soft switch for starting to wash the buttocks with a softer water flow. Is operated in the same manner, and a detailed description thereof will be omitted.

In this embodiment, the pulsation generator 17 is arranged downstream of the heat exchanger 14. This not only provides unnecessary pulsating pressure in the heat exchanger 14 but also
Pulsation generator 1 to suppress pulsation pressure attenuation in piping
This is for disposing 7 as close as possible to the water discharge section.

The pulsation generator 17 is arranged upstream of the flow path switching and flow regulating valve 18.
It may be provided between the flow path switching and flow control valve 18 and the flow path switching valve 20. In this case, the body of the nozzle cannot be cleaned with the pulsating cleaning water.
7 can be arranged closer to the water discharge portion, and the effect of suppressing the pulsation pressure attenuation in the pipe is increased.

The pulsation generator 17 is configured to be driven during all operations of pre-cleaning, nozzle body cleaning, soft start, main cleaning, and post-cleaning. Only the driving may be performed. Further, a selection switch may be provided so that the user can select whether to drive or stop the pulsation generator 17 in each operation.

Although a seat switch is taken as an example of a means for detecting approach or use of a human body, a detection switch or the like for detecting an operation in which a toilet lid changes from a closed state to an open state may be used.

Further, when the approach or use of the human body is detected, the water heating control is automatically started.
A power saving switch that allows the user to select whether or not to perform this control may be provided. In this case, if the user sets the power saving switch to ON, the water flow heating control is not automatically started even when the approach or use of the human body is detected, thereby contributing to more power saving. However, at this time, even if the user presses the switch for starting the washing, the washing water at an appropriate temperature cannot be discharged immediately.
It is preferable to perform control such that the cleaning water is heated to an appropriate temperature by activating the cleaning water.

As means for changing the discharge destination of the washing water between the nozzle discharge port and the drainage position, a flow path switching and flow control valve 1 is provided.
Although the example of FIG. 8 is taken as an example, nozzle driving means for controlling the movement of the nozzle may be used. In this case, the cleaning water may be discharged from the nozzle discharge port when the nozzle is extended and from the drainage position when the nozzle is stored.

Further, the float switch 30 is taken as an example of the water level detecting means for preventing empty heating, but a means using an air detecting thermistor using a thermistor, a method for detecting a water level using an electrode, and a method using light refraction are used.
