Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary washing device for washing private parts of the human body with washing water.

BACKGROUND TECHNOLOGY In general, sanitary washing devices (hereinafter abbreviated as water supply direct connection) that have a washing water discharge means for discharging washing water to the private parts of the human body using the pressure of the water supply, use a first method as a means for controlling the flow rate of washing water. As shown in Figure 2, in the middle of the waterway from the water pipe to the cleaning nozzle 1, there is a valve mechanism 4 whose opening degree changes depending on the angle of the rotating shaft 4a, and a solenoid valve 2 that opens the waterway when energized. There is. That is, the user sets the angle of the rotary shaft 4a so that the flow rate of the washing water becomes a desired value, and the electromagnetic valve 2 is opened and closed by turning on and off the washing switch 5a.
Starting and stopping cleaning.

The problem to be solved by the invention is that in such a configuration, the opening degree of the valve mechanism 40 is
Since it is constant unless the angle of the rotating shaft 4a is changed,
When the user turns on the cleaning switch 5a, a sudden discharge of cleaning water occurs, giving an unpleasant impression to the user. In addition, it is necessary to turn the rotating shaft 4a several times to change the opening degree of the valve mechanism 4d from the fully closed state to the fully open state, and the user has to perform a very troublesome operation when setting the flow rate. This has the problem that not only is the current setting not known, but the current setting is unknown. Note that 3 is a water heating means, and 5 is a control circuit.

The present invention solves these conventional problems, and by electrically controlling the flow rate of the washing water,
To provide an excellent sanitary washing device which discharges washing water slowly and is easy to set the flow rate.

Means for Solving the Problems The sanitary washing device of the present invention comprises: a water heater for heating washing water for washing private parts of the human body; a washing water discharging means directly connected to the water supply; and a washing water discharging means provided in the middle of the washing water discharging means. The apparatus further includes a valve mechanism for controlling the flow rate of the washing water according to the angle of the rotating shaft, a step motor mounted coaxially with the rotating shaft, and a control circuit for driving the step motor.

Function The sanitary washing device of the present invention uses a step motor to electrically control the flow rate of the washing water by changing the opening degree of the valve mechanism.

This makes it possible to automatically increase the flow rate gradually at the same time as turning on the cleaning switch and stop it at the set value, eliminating the need for particularly troublesome operations when setting the flow rate. .

Further, by providing a display device, the current setting value can be easily known.

EXAMPLE Hereinafter, a sanitary cleaning device according to an example of the present invention will be explained with reference to the drawings.

As shown in FIG. 1, a step motor 10 coaxially connected to a rotating shaft 4a of a valve mechanism 4 is driven by a microcomputer (hereinafter referred to as microcomputer) 7 via a drive circuit 6 of a control circuit 5. The setting of the flow rate of the cleaning water is input to the microcomputer 7 as the angle of the rotation shaft 4a of the valve mechanism 40 through the operation panel 9, and is displayed on the display circuit 8 at the same time as being stored in the internal memory 7a. on the operation panel 9,
When the cleaning switch 5a is turned on, the microcomputer 7 opens the solenoid valve 2 according to a preset program, and then gradually rotates the step motor 10 at a speed that does not cause the cleaning water to be released suddenly.

The rotation shaft 4a of the valve mechanism 4 is connected to the internal memory 7.
When the angle stored in point a is reached, the rotation of the step motor 10 is stopped, thereby reproducing the set flow rate of the cleaning water.

In addition, 1 is a nozzle, 3 is a water heating means, and 11 is a washing water flow rate detection means.

Effects of the Invention As described above, in the sanitary washing device of the present invention, the washing water valve mechanism connected coaxially with the step motor is driven by the control circuit, thereby preventing the washing water from being suddenly released.
It is extremely easy to set the flow rate, and the set value of the flow rate can be easily known, which is extremely advantageous in practice.

In addition, in the above embodiment, the washing water flow rate detection means 1
1, if the microcomputer 7 applies negative feedback to the flow rate control of the cleaning water, it is possible to suppress pulsations in the flow rate of the cleaning water due to pressure fluctuations of the tap water, and the effects of the present invention are further enhanced. .
