DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cleaning device for cleaning private parts with cleansing water after defecating.

Structure of a conventional example and its problems A conventional cleaning device will be explained based on FIG. 1.
1 is a toilet main body, 2 is a toilet seat for a user to sit on the toilet main body 1, 3 is a washing means (hereinafter referred to as a washing nozzle) for discharging washing water to the private parts of the user, 4
is a cistern, 5 is water stored in the cistern, 6 is a water filter submerged in the water 5,
Reference numeral 7 denotes a washing water supply means (hereinafter referred to as a pump) that sucks the water 5 from the water filter 6 and sends the washing water to the washing nozzle 3, 8 a hot water storage tank provided in the waterway of the washing water supply means, and 9 a water storage tank provided in the waterway. The hot water storage tank 8
A heater heats water to the optimum temperature for cleaning using a built-in thermostat (omitted in FIG. 1), and 10 is a storage box that houses the pump 7, hot water tank 8, and the like. 11 is a control box coupled to the storage foil 10; 12 is a controller incorporating control means for energizing the pump 7, the heater 9, etc.;
Reference numeral 13 is a cleaning switch that issues a command to energize the pump 7 via the controller 12, and 14 is a setting means that sets the amount of cleaning water to be discharged to the private parts. Note that 15 represents cleaning water discharged from the cleaning nozzle 3.

In the above configuration, when the user washes his private parts, he sits on the toilet seat 2, presses the washing switch 13, operates the washing water amount setting means 14, energizes the pump 7, and energizes the washing water 15. You can wash your private parts with this. The user can change the amount of energization of the pump 7 using the setting means 14, so that the user can wash his/her private parts with the desired amount of washing water. Further, when it is desired to end the cleaning, the cleaning is completed by pressing the cleaning switch 13 again.

In this configuration, if the user operates the cleaning switch 13 while leaving the cleaning water amount setting means 14 set to "strong" and finishes cleaning,
The moment the next user presses the washing switch 13, a strong amount of washing water hits the user's private parts, giving the user a shock sensation and causing pain and discomfort to people with hemorrhoids. Ta.

In addition, each user has a certain amount of cleansing water that can be applied to the private parts without causing pain, and the user has to press the cleansing switch and then adjust the setting means 14 to obtain the appropriate amount of cleansing water, which is troublesome. Ta.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and aims to improve the usability of cleaning operations.

Structure of the Invention In order to achieve this object, the present invention provides a cleaning means for cleaning private parts of the human body, a water supply means for supplying cleansing water to the cleaning means, a setting means for setting the amount of water in the water supply means, and a water supply means for setting the amount of water in the water supply means. and a separately provided cleaning switch, and after pressing (turning on) the cleaning switch, the cleaning water is discharged at a constant amount regardless of the setting means until the setting means is operated, and when the setting means is operated, It has a control means for controlling the amount of water set by the setting means.

With this configuration, at the start of cleaning, even if the setting means is set to "strong", a strong amount of washing water is not discharged, but a constant amount of water is discharged, and when the setting means 14 is operated. For the first time, it has the ability to adjust the amount of water to the user's preference.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Note that the structural members of the conventional example shown in FIG. 1 are employed as they are in the embodiment of the present invention, and the same members are given the same numbers.

FIG. 2 is a schematic diagram of a control circuit for a cleaning function according to an embodiment of the present invention.

Reference numeral 12 denotes a controller that inputs setting values of the cleaning switch 13 and setting means 14 (variable resistance in one embodiment of the present invention) and energizes the pump 7 and the like. 3
is a cleaning nozzle that discharges the cleaning water supplied from the pump 7.

16 is a control means (for example, a microcomputer) built into the controller 12;
is a detection means for detecting the set value of the 14 setting means.

In the above configuration, when cleaning is started by pressing the cleaning switch 13, the control means 16 detects whether the initial setting value of the setting means 14 has changed (whether or not the user has operated the setting means).
7 is constantly monitoring. If there is no change in the initial setting value of the setting means 14, the control means 16 energizes the pump 7 to discharge a certain constant amount of water irrespective of the initial setting value of the setting means 14. This cleaning pattern is shown in Figure 3a.

However, when the user operates the setting means 14, the detection means 17 detects that a change has occurred in the initial setting value at the start of cleaning (point bA in FIG. 3), and the control means 16 immediately The pump 7 is energized to control the amount of water according to the setting value of the setting means 14.

This cleaning pattern is shown in FIG. 3b, which shows how the amount of cleaning water set by the setting means 14 is discharged after the setting means 14 is operated (point A).

Therefore, even if the cleaning switch 13 is pressed and the setting means 14 is set to "strong" at the start of cleaning, strong cleaning water will not be discharged, and the setting means will not be released until the user operates the setting means 14. The amount of water is controlled to a set value of 14. In the above embodiment, a pump is used as the water supply means, but it goes without saying that tap water may be directly supplied to the nozzle without using a pump, and a flow rate control valve may be used as the water supply means in that case.

Next, another embodiment of the present invention will be described using FIG. 4.

In FIG. 4, the setting means 14 is not a variable resistor but a rotational direction output signal generating means (hereinafter referred to as a rotary encoder).

In the above configuration, when the rotary encoder 14 is not operated at the start of cleaning, the control means 16 discharges cleaning water at a certain constant amount as described in the embodiment of the present invention, and when the rotary encoder 14 is operated, the The amount of cleaning water is controlled according to the direction of rotation of the encoder.

Now, the operation of the rotary encoder will be explained using FIG.

FIG. 5 is a partially cutaway schematic view of the rotary encoder 14, which constantly outputs two pulses α and β, and its operation will be explained using FIGS. 6a and 6b.

By the way, when the rotary encoder 14 is turned in the direction A, the pulse α is as shown in FIG. 6a.
It outputs a little faster than the β pulse. Conversely, when turning in the B direction, the β pulse is output earlier than the α pulse. Which of the two pulses α and β came out first (or is called the phase relationship between α and β)
This allows the direction of rotation to be detected. Therefore, the control means 16 detects the phase relationship between the signals of the two pulses α and β, and for example, when the user turns it in the A direction, the amount of water released is stronger than the amount of water released at a constant amount at the start of cleaning. , and conversely, when turned in direction B, a weaker amount of water is released than the constant amount of water at the start of washing, and thereafter the amount of washing water is controlled according to the direction of rotation.

If the user wants to change the constant amount of water from the start of cleaning, the user can adjust the amount of cleaning water only by rotating the rotary encoder, resulting in the following effects.

(1) Compared to the case where the setting means is a variable resistance, the strength of the amount of washing water can be changed only by the direction of rotation, making the operation easier to understand and handle.

(2) The setting means generates two pulse signals, which are digital quantities of ON (ON) and OFF (OFF), and the setting values are reliable, and the setting means itself will not deteriorate due to long-term use. do not have.

Effects of the Invention The sanitary cleaning device of the present invention comprises a cleaning means (cleaning nozzle) for cleaning private parts of the human body, a water supply means for supplying cleaning water to the cleaning means, a setting means for setting the amount of water of the water supply means, and the setting means. and a separately provided cleaning switch, which discharges cleaning water at a constant amount at the start of cleaning, regardless of the setting value of the setting means, and when the setting means is operated, the setting value of the setting means is changed. Since it has a control means for controlling the amount of water, it has the following effects.

(1) The user presses the cleaning switch and cleanses with a certain amount of water at a certain strength. If the user is satisfied with that, the user can clean the private parts with just one operation, that is, turning the cleaning switch on and off, so there is no need to use the setting means. This makes the operation extremely easy and convenient for everyone from children to the elderly.

(2) At the start of cleaning, a strong amount of cleaning water is not released, so the user does not feel a shock, and by operating the setting means, the user can perform cleaning according to the condition of his/her private parts.
