Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sanitary cleaning device for cleaning private parts with hot water or the like after using the toilet.

BACKGROUND OF THE INVENTION FIG. 5 is a flow rate-pressure setting graph showing the control characteristics of the flow rate ejected from the cleaning nozzle of a conventional sanitary cleaning device.

In the conventional example shown in FIG. 5, the washing water is set at a flow rate value Q1. It was Q2...Q5.

This flow rate value is 0. ．． 02...Q5 is a setting in which each flow rate is equally divided. In this conventional washing water setting, the sensation that a human feels when a jet collides with the jet corresponds to the momentum of the jet, so the strength of the jet is not felt at regular intervals. That is, the flow rate Q
,,02, the change in the jet flow is difficult to understand, and Q,1,0
5, on the other hand, the change in jet flow seems to be large. As described above, in the conventional washing water setting method, there is an imbalance between the operating sensation and the sensation that a person actually receives from the jet stream, resulting in an unsatisfactory usability.

Problems to be Solved by the Invention The setting of the washing water of the sanitary washing device is such that the jet sensation that a person expects during operation and the sensation when the part to be cleaned actually receives the jet flow does not match, resulting in a sensuous problem. This is an attempt to solve the problem of imbalance.

Means for Solving the Problems In order to solve the above problems, the water t is set so that the momentum of the jet stream impinging on the part to be cleaned is approximately equal.

Effect The impact force of the jet flow is equal to the momentum, that is, assuming the impact force F, flow velocity V, and quality i1m, F=mv.

Also, flow@0. If the cross-sectional area of the injection port is S, then rn=
pQ, v=Q/S, therefore, F=p02, and the flow rate values are set so that eQ2 is equally spaced.

Example Embodiments of the present invention will be described based on FIGS. 1 to 4.

Reference numeral 1 denotes a sanitary cleaning device, which is composed of a cleaning device main body portion 2 and a heated toilet seat portion 3. 4 is a cleaning nozzle, and 5 is a toilet bowl.

In FIG. 2, 6 is a pressure feeding means, 7 is a hot water heating unit, 8 is a gas turbine, 9 is a water intake port equipped with a filter, and 10 is a solenoid valve for opening and closing a cleaning channel. Reference numeral 11 denotes a control means consisting of an operating section microcomputer and a circuit section;
0, and also controls the morph rotation speed of the pressure feeding means to control the flow rate.

FIG. 3 is a circuit diagram showing an embodiment of the flow rate control means, in which 12 is a rectifier circuit for generating the motor voltage of the pressure feeding means 6;
3 and 14 are triacs for turning on and off the electromagnetic valve 9 and the pressure feeding means 5, respectively.

FIG. 4 is a jet flow characteristic graph of the cleaning nozzle 4, in which the horizontal axis shows the flow rate Q and the vertical axis shows the momentum F. Ql, Q2...Q5 are flow rate set values, and F,, F2...F5 indicate the corresponding momentum.

The operation based on the above configuration will be explained. When a cleaning switch (not shown) in the operation section is turned on, a signal is issued from the microcomputer, the triacs 13 and 14 are energized, and the solenoid valve 10 is opened and the motor of the pressure feeding means 6 is also started. The water sucked from the gas station 8 is pressurized by the pressure feeding means 6, heated by the hot water heating unit 7, and then jetted from the cleaning nozzle 4 to hit the area to be cleaned and perform a cleaning action. Next, consider the purpose of cleaning and the dirt on the area to be cleaned.
When the water volume setting button on the operation unit is operated, the microcomputer calculates the applied voltage of the pressure feeding means 6, and the voltage is calculated as Ql, Q2 and Q2 in FIG.
...A voltage corresponding to the flow rate corresponding to Q5 is applied to the motor. Since the motor rotates according to the applied voltage, the pump pressure changes depending on the rotation speed, and the set flow rate Q1. Q2
...obtains Q5. The flow rates Q1, Q2, . In this way, the flow rate is set to equally divide the amount of momentum that is approximately equal to the human sense of the jet flow, and changes in the jet flow adjustment can be accurately sensed.

Effects of the Invention The sanitary cleaning device can
The jet flow from the cleaning nozzle is adjusted, and by adjusting the amount of adjustment so that the momentum is equally divided, the set value and the feeling of the jet fluid match. As a result, the selection of adjustment setting values becomes smoother, and the changes when changing the setting values can be grasped intuitively, and the comfort during use can be improved.
