Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides cleaning by intermittently spraying cleaning water at a set water pressure onto the private parts of the human body at arbitrary intervals. The present invention relates to a human body private parts cleaning device that has improved performance and improved usability.

(Prior Art) Conventionally, in order to improve the usability and cleaning effect of a human body private part cleaning device, a method has already been known for improving the jetting state of cleaning water sprayed onto the private part to be cleaned. For example, the
According to No. 91239, there is provided a fluctuation control means for commanding fluctuations that change the strength of the washing water, and a fluctuation control means for generating fluctuations in the washing water, that is, for ejecting strongly or in response to a control signal from the fluctuation control means. 2. Description of the Related Art A sanitary washing device is known that has a washing water supply control means that weakly sprays washing water. In this device, the amount of water jetted to the private parts to be cleaned (that is, the water pressure jetted) is adjusted by controlling the phase of the motor that drives the pump. A block diagram of the control is shown in FIG. Fluctuations in the washing water of the sanitary washing device are determined by controlling the washing water at two positions: an upper limit UL and a lower limit LL centered on the washing water volume set value SL set by the user of the sanitary washing device. It was gushing.

Therefore, at the upper limit value UL, the amount of washing water received by the user is large and the water pressure is strong, and at the lower limit value LL, the amount of washing water is small and the water pressure is weak. . Therefore, the user receives cleaning water whose water pressure changes by the difference between the UL and the SL.

(Problems to be Solved by the Invention) The present invention has discovered that the cleaning effect when jetting water is high, and by supplying jet water intermittently and by arbitrarily changing the intermittent period, cleaning can be achieved. It is an object of the present invention to provide a human body private part cleaning device that improves the feeling of use and provides a good cleaning effect.

The toilet main body 10, nozzle 40, and nozzle drive device 30 that constitute the human body private parts cleaning device of the present invention can be those of conventional human body private parts cleaning devices as they are.

The cleaning command means 21 of the water supply device 20 includes a nozzle 4
This means is composed of an intermittent supply command section 23 that commands generation of at least intermittent water pressure of cleaning water jetted from zero, and an intermittent cycle command section 25 that inputs the intermittent cycle. Specifically, the intermittent cycle command unit 21 is a push button switch, a slide switch, etc., and in special cases, a voice input switch, a foot-operated switch, etc. can be used. The intermittent cycle command section 25 can also utilize the same switches as the intermittent cycle command section. Further, it is preferable that the cleaning commanding means 21 has a display device for displaying the results of other commands. As the indicator, for example, a level display using a lamp or an LED can be used.

The control device 27 is a device that outputs at least a control signal for generating intermittent water pressure with a variable period in response to a signal input from the cleaning command means 21. The control device 27 may output a control signal for controlling a nozzle drive device, which will be described later.
As the control device 27, for example, when realized by an electric circuit, a switching element such as a relay or a transistor, a comparator, a microcomputer, etc. can be used.

The water pressure generator 29 is a device that generates water pressure in cleaning water and supplies it to the nozzle in response to a control signal from the control device 27, and is capable of generating cleaning water pressure intermittently and at a variable period. is necessary. A pump and a motor can be used as the water pressure generator 29. In addition, a water pressure source such as local water pressure from a water supply tank disposed at a high place, or simply water pressure from a tap can be used.

The motor used in the water pressure generator 29 is preferably a step motor.

Further, in order to generate water pressure intermittently, which is a feature of the device of the present invention, for example, when a rotating machine such as an electric motor is used to generate steady water pressure, the following mechanical parts can be used.

For example, water pressure direction control using an electromagnetic directional control valve that switches and controls the supply direction of the steady water pressure and supplies the steady water pressure to the nozzle intermittently can be used.

Alternatively, an electromagnetic clutch inserted between the pump and the output shaft of the electric motor that is the driving source can be used.

Alternatively, a relief valve disposed in the output system of the pump can be used. This relief valve is also a type of electromagnetic directional control valve as referred to in the present invention.

Alternatively, if a step motor is used as the drive source for the pump, a control device can be used to control the drive of the step motor.

To adjust the time ratio between the intermittent supply and stop of water pressure to the nozzle, for example, a well-known monostable multivibrator circuit or a circuit combined with an ON timer can be used.

The nozzle drive device 30 is a device for positioning a nozzle, which is extendably or rotatably held in the toilet bowl 10 body, and a spout of the nozzle on the toilet bowl body 10. As a drive source for the nozzle drive device 30, for example, a rotating machine such as an electric motor, an electromagnetic force,
Pneumatic pressure, water pressure, etc. can also be used.

(Function) The toilet main body 10 holds the nozzle 40 in a telescopic or rotatable manner, supports part of the weight of the user of the toilet, and supports the posture of the user of the toilet. The toilet user,
When the cleaning water is to be spouted intermittently at a predetermined period, the cleaning command means 21 of the water supply device 20
Necessary commands are input to each of the intermittent cycle command section 25 and the intermittent supply command section 23 included in the . The cleaning command means 21 outputs a command signal to the control device 27 according to the input command. The control device 27
Based on the command signal inputted from the cleaning command means 21, the controller outputs a control signal having a predetermined period and intermittently generating cleaning water pressure to the water pressure generating device 29. The water pressure generator 29 generates washing water pressure intermittently and at a predetermined period, and supplies it to the nozzle 40 . Note that when the nozzle 40 is controlled by the control device 27, before the control device 27 sends a command signal to the water pressure generator 29, it first outputs a control signal for a positioning command for the ejection port of the nozzle 40 to the nozzle drive device 30. do. The nozzle drive device 30
The step is to position the nozzle 40 from the storage position to a predetermined position. When the positioning is completed, the control device 27 controls the water pressure generating device 25.

The nozzle 40 intermittently cleanses the user's private parts by ejecting water at a water pressure and at a desired cycle as expected by the user. That is, by intermittently spraying the wash water, the effect of washing the private parts is improved, and the user of the toilet bowl is washed without feeling uncomfortable. When a predetermined time elapses or when a stop command signal is input from the cleaning command means 21, the control device 27 outputs a stop signal to the water pressure generator 29 and causes the nozzle drive device 30 to move the nozzle 40 to the storage position. outputs a control signal for return command. Therefore, the jetting of cleaning water from the nozzle 40 is stopped, and the nozzle 40 is driven by the nozzle driving device 30 and returns to the predetermined storage position.

[Examples] Hereinafter, the present invention will be described in detail based on specific examples. FIG. 2 is a block diagram illustrating a human body private part cleaning device according to a specific embodiment of the present invention.

A toilet main body 10 used by a toilet user 3 is provided with a water tank 11 for storing flush water.

The cleaning command means 21 of the water supply device 20 is comprised of an operation panel 210 whose details are shown in FIG.

Therefore, this operation panel 210 constitutes the intermittent supply command section 23 and the intermittent cycle command section 25 in the present invention.

This intermittent supply command unit 23 includes a self-memory push button switch 211 that commands intermittent jetting and continuous jetting,
213, setting switches 231 and 233 that allow the user to set the water pressure desired by the user in an analog manner by pressing and holding to set the water pressure downward and upward, respectively, and display the water pressure to be ejected.
It is composed of a jet pressure strength display board 235 coupled with an LED level meter.

In addition, the above-mentioned intermittent cycle command unit 25 can extend the jetting time of the cleaning water by continuing to press it.
Shortening ejection time setting switch 251, 252
, stop time setting switches 253 and 254 for setting the same wash water stop time, and a jet time display board 255 having the same structural outline as the jet pressure strength display board 235 and displaying the wash water jet time, The stop time display board 256 displays the stop time.

The control device 27 includes an input/output interface 27
1,275 and a microcomputer 273 (Fig. 2).

The water pressure generation device 29 includes a water storage tank 295 that stores cleaning water led from the water supply tank 11 through a hose 13, a pump 293 that is connected to an induction motor 291 via a spline shaft and generates water pressure, and a built-in solenoid (Fig. An electromagnetic water pressure directional control valve (electromagnetic directional control valve in the present invention) 294 that switches and supplies the water pressure to either the tank 295 or a nozzle 40 (described later) according to an excitation current supplied to the tank (not shown). and a flow rate control valve 292 that adjusts the flow rate passing through the ports 292B and 292C by an excitation current applied to a solenoid 292A, the details of which are shown in FIG. Figure 4 shows a circuit diagram from water pressure generation to discharge.

The nozzle drive device 30 is realized by expanding and contracting a leaf spring that changes according to the rotation of the motor 31.
The nozzle 40 is provided with a shower port 41 that spouts cleaning water only in the upper part.

Next, the operation of the apparatus of this embodiment will be explained according to a flowchart of processing performed by the microcomputer 273 (hereinafter simply referred to as "computer") shown in FIG.

The computer has push button switches 211, 213
When one of the buttons is pressed, execution starts from step 100. Step 100 is the initial setting, that is, the standard intermittent cycle when spraying cleaning water intermittently.
This step is to input and set the water jet pressure from a pre-stored memory. Once the execution is complete,
It is displayed on the central portion 218A of the display board 235.

Step 102 is a step in which the toilet user sets the ejection conditions. That is, the toilet user first inputs the jetting water pressure from the cleaning water pressure setting switches 231 and 233. The computer then activates the solenoid 292A of the flow control valve 292 in response to the input.
A predetermined current is applied to the That is, port 292
A large amount of water returning from C to the tank 255 indicates that the water pressure of the cleaning water jetted from the nozzle 40 is low. Furthermore, the toilet user inputs setting conditions from the squirt time setting switches 251, 252 and stop time setting switches 253, 254, and inputs the cycle for intermittently squirting the flushing water. When the aforementioned setting switches 231, 233, 251 to 254 are operated, the display boards 235,
Displayed on LEDs at 255 and 256. When either the push button switch 211 or 213 is pressed and a certain period of time has elapsed, the process moves to the next step 104 even if the ejection time, stop time, etc. are not set.

Step 104 is a step for positioning the ejection port of the nozzle at a predetermined position.

Steps 106 to 110 are steps for generating washing water pressure. That is, in step 106, it is determined whether the cleaning water to be ejected is continuous or intermittent, and if continuous ejection is required, that is, if the push button switch 213 is pressed in step 102, the process jumps to step 114. Then, based on the initial settings set in step 100 or the conditions set in step 102, control signals are output to the electromagnetic hydraulic directional control valve 294, flow rate control valve 292, and dielectric motor 295.

If the intermittent command is issued in step 102, that is, the push button switch 211 is pressed, the process moves to step 108. Step 108 is a step in which washing water pressure is intermittently generated based on the conditions set in step 102 or the initial settings in step 100. In steps 108 and 114, cleaning water at the water pressure set on the display plate 218 is ejected from the shower port 41 of the nozzle 40 in both steps.

When step 108 is executed, the washing water pressure discharged from the output port 294A of the electromagnetic hydraulic directional valve 294 is shown in FIGS. 6 to 8. Each figure shows that the intermittent cycle consisting of the flushing water pressure 61 set by the toilet user and the zero water pressure 63 is set in three ways.

Until the command to stop cleaning is entered in step 110,
In other words, the routine of steps 106 to 110 is repeated until the one of the push button switches 211, 213 that has been pressed and stored in its own memory is pressed again and returns to its original state. If it is determined in step 110 that a stop command has been input, the induction motor 291 is stopped in the next step 112, and the pump 253 stops generating water pressure. Thereafter, the process moves to step 120, where the motor 31 of the nozzle drive device 30 is driven, and the nozzle 40 returns to its initial position.

According to this embodiment, self-memory push button switches 211 and 213 are provided to command the washing water to be ejected from the shower port of the nozzle 40 continuously or intermittently, so that the washing water is ejected to the private parts. The method can be confirmed. Setting switches 251 to 25 for separately setting washing water jetting, time, and stop time
4, cleaning water can be sprayed locally at any intermittent intervals. By configuring the system with a control device using a microcomputer, the pressure of the cleaning water that is ejected is intermittently set at the specified cleaning water pressure, eliminating anxiety about the cleaning water pressure and providing a comfortable cleaning sensation. The cleaning effect is also improved by intermittent cleaning. Further, even during the jetting of the cleaning water, the commands for continuous jetting and intermittent jetting can be switched between each other.

In this example, the intermittent period of jetting out cleaning water is
Although the method of setting the ejection time and the stop time individually was used, a method of setting the ratio of the ejection time and the stop time can also be used.

[Effects of the Invention] According to the present invention, by disposing a water supply device that intermittently supplies cleansing water for cleaning the toilet bowl body and private parts to the nozzle, and the intermittent period is variable, it is possible to The period of intermittent jetting of cleaning water is not constant,
Cleaning water can be spouted intermittently at any cycle the toilet user prefers. Therefore, an improved cleaning feeling and cleaning effect can be obtained compared to conventional devices.
