Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary cleaning device for cleaning private parts of a human body after defecating by discharging cleaning water.

Structure of the conventional example and its problems As shown in FIG. 1, the structure of the sanitary washing device related to the present invention is that a toilet seat 3 and a device main body 4 are installed on a toilet bowl 2 having a toilet 1. A nozzle 5 is installed at the bottom to discharge cleansing water to the private parts of the human body sitting on the stool P''4. A pump 7 that supplies the drawing nozzle 5 and its water supply pipe s
a, sb, and a shutoff means (electromagnetic valve) 9 that shuts off the water supply.
and an energizing means 11 that energizes the pump 7 and the solenoid valve 9 to perform cleaning using a built-in cleaning switch 1o.

As shown in FIG. 2, the conventional biasing means 11 has a configuration including a power source 12, a pump biasing circuit 13, and a solenoid valve biasing circuit 14.
During cleaning, by turning on the cleaning switch 1o, the pump energizing circuit 13 and the solenoid valve energizing circuit 14 are activated, and the pump 7 and the solenoid valve 9 are simultaneously energized to perform cleaning.

However, with this configuration, if there is even a slight delay in opening the solenoid valve 9, the pressure of the water in the water supply pipe 8a will increase instantaneously due to the pump 7, causing vibration noise in the device body 4, or causing the pump to stop due to pressure. However, the electromagnetic valve 9 deteriorates, and in the case where a motor is used as the pump 7, the motor performs tax adjustment, resulting in noise generation and a decrease in reliability.

Purpose of the Invention Page 3 The present invention is intended to solve such conventional problems, and its first objective is to prevent high pressure from being generated in the water supply pipe at the start of cleaning.

Structure of the Invention In order to achieve this object, the present invention is provided with an energizing means that energizes the pump with a delay when the shutoff means (electromagnetic valve) is opened. With this configuration, when starting cleaning, the electromagnetic valve is first opened and the pump is energized after the water supply channel is opened, so that high pressure is not generated within the water supply pipe.

DESCRIPTION OF EMBODIMENTS FIG. 3 is a block diagram of a biasing means in an embodiment of the sanitary cleaning device of the present invention.The difference from the conventional one shown in FIG. This is because a delay timer 15 is added.

When the cleaning switch 10 is turned on at the start of cleaning in the configuration described in 2, the solenoid valve energizing circuit 14 is activated, the solenoid valve 9 is energized, and the cleaning water supply channel is opened. However, due to the action of the delay timer 15, the pump energizing circuit 13 is not yet activated and the pump 7 remains deenergized. After a certain period of time, for example one second, the delay timer 15 is turned on, the pump energizing circuit 13 is activated, and the pump 7 is energized to supply cleaning water to the nozzle 5 and start cleaning. Although it is preferable for the delay time of the delay timer 15 to be as short as possible from the viewpoint of usability of this device, it is necessary to set it to a time longer than the maximum time including variations in at least the time required to open the solenoid valve 9. Usually, it is set to 0.5 to 1 second.

Although the delay timer is connected before the pump energizing circuit in the embodiment, the same effect can be obtained even if the delay timer is connected after the pump energizing circuit.

Effects of the Invention Since the sanitary cleaning device of the present invention has an energizing means that energizes the pump with a delay when the shutoff means is opened, the water pressure in the water supply pipe does not increase instantaneously, and the imaging sound at the beginning of cleaning is reduced. This eliminates the occurrence of noise, makes operation quieter, and eliminates the need for high pressure to be applied to the pump or shutoff means, eliminating deterioration due to pressure and increasing the reliability of the device.
