[Prior Art] A local cleaning device is provided in a form attached to a Western-style toilet bowl, and performs anus cleaning and bidet cleaning by blowing hot water from a nozzle, and is very useful for cleaning a local portion. Things.

[Problems to be Solved by the Invention] However, since the local cleaning device has a constant amount of cleaning water, it has been difficult to satisfy all the cleaning water amounts required by the user.

In other words, when a large amount of washing water is required, the amount of supply water must be increased to satisfy this.However, to increase the amount of supply water, the pump motor must be large in view of the pump motor rating, heat generation, noise, etc. As a result, there is a problem that the local cleaning device becomes large.

Further, when the amount of supplied water is increased, there is a limit to the supply capacity in the hot water tank provided in the local cleaning device, so that there is a problem that the cleaning time is shortened. The present invention has been made in view of the above-described problems, and has as its object to increase the amount of washing water without using a large pump motor so that the amount of washing water desired by a user can be satisfied. The period for increasing the water volume can be set by the user's intentional operation. Accordingly, it is an object of the present invention to provide a local cleaning device that can expect a massage effect.

Means for Solving the Problems In order to achieve the above object, the present invention provides a drive circuit for driving a pump motor for driving a pump for pressurizing hot water stored in a hot water tank and ejecting the hot water from an ejection nozzle. A switch that issues a command to drive the pump motor beyond a certain rating when operated, and a drive circuit that controls the drive circuit based on the command by operating the switch to drive the pump motor that exceeds a certain rating. And a control circuit for maintaining the switch during operation.

[Operation] According to the present invention, when the user wants to increase the amount of washing water, the user only has to operate the switch, and the period of the increase is only during the operation of the switch. Can be shortened, and as a result, the effect on the life of the pump motor can be reduced. In addition, by repeating the operation and non-operation, the amount of washing water is intermittently changed, so that stimulation is given to the washing portion, and a massage effect can be expected.

EXAMPLES The present invention will be described below with reference to examples.

FIG. 1 shows the structure of the mechanical part of the embodiment, and FIG. 2 shows the structure of the circuit part. The pump 2 such as a gear pump is driven by the driving of a pump motor 1, and a low tank (FIG. (Not shown), etc. through the filter 3
The water that has been absorbed and pressurized is pumped into the hot water tank 4, and the hot water previously stored in the hot water tank 4 is pushed out toward the solenoid valve 5, and the solenoid valve 5 is switched to eject a cylinder-type jet for bidet cleaning. The nozzle is ejected from a nozzle (not shown) or a cylinder-type ejection nozzle 6 on the anal cleaning side.

The drive of the pump motor 1, the switching of the electromagnetic valve 5, and the heating control of the hot water in the hot water tank 4 are performed by a control circuit 7 comprising a microcomputer shown in FIG.

The control circuit 7 discriminates an operation signal sent from the controller 17 shown in FIG. 3 and controls each section based on each operation signal. A drive circuit for driving the pump motor 1 is provided at a control output port. 8, an energization control circuit 10 for the hot water heater 9, an energization control circuit 12 for the hot air heater 11 for drying,
Drive circuit 14 for fan motor 13 for blowing hot air, switching control circuit 15 for solenoid valve 5, and display element for displaying water volume
L ₁ ... at least connected to the drive circuit 16, and also to the input port and the anus washing switch SW _1, a bidet switch SW _2, the drying switch S for blowing drying hot air
And W _3, high for setting the amount of water during the washing, and the switch SW _4, SW ₅ for low setting, to increase the quantity of cleaning water by driving the pump motor 1 over a certain rating (120%) increase switch SW ₆ to issue a command, and connects the locking switch SW ₇ for stopping the operation.

These switches SW _{1 to} SW ₇ are constituted by push button switches, and are provided in the controller 17 together with the display elements L ₁ .

 Next, the operation of the local cleaning device of the present invention will be described.

First, in an initial state in which a power switch (not shown) is turned on, the pump motor 1 is driven to store water in the hot water tank 4 by the pump 2, and electricity is supplied to the hot water heater 9 through the electricity supply control circuit 10, and the water in the hot water tank 4 is discharged. Heat to a constant temperature of hot water. In this heating, a power supply control circuit 10 controls the power supply to the hot water heater 9 by a phase control or the like based on a signal from a control circuit 7 based on a detection signal from a hot water detection element (not shown) such as a thermistor. To keep it.

The operation after entering the standby state from the initial state will be described with reference to the flowchart of FIG.

First, anal washing switch SW ₁ in is pressed in a standby state, the cleaning water quantity control circuit 7 is set (water force)
Is checked, and the drive of the pump motor 1 is controlled through the drive circuit 8 so as to correspond to the set washing water amount.
Start driving.

When the operation of the pump 2 is started, water is sucked into the hot water tank 4 from the low tank. The water pressurized and fed into the hot water tank 4 pushes hot water stored in advance toward the solenoid valve 5. At this time, the control circuit 7 switches the solenoid valve 5 to switch the flow path to the anal cleaning jet nozzle 6 by the control circuit 15, and sends the pushed hot water to the jet nozzle 6.
Since the ejection nozzle 6 is of a cylinder type, it is raised toward the anus by the pressure of the supplied hot water, so that hot water is ejected from the nozzle opening at the tip toward the anus to perform anal cleaning. The washout period is predetermined to approximately 10 to 30 seconds, and the period counted by an internal timer holds the driving of the pump motor 1 until the elapse of the washing period from the time of the operation push the anal washing switch SW ₁ in After the elapse of the cleaning period, the driving of the pump motor 1 is stopped, and the supply of hot water to the ejection nozzle 6 is stopped. Therefore, the pressure of the hot water is lost, and the ejection nozzle 6 returns to the original state.

Setting of the washing water by pressing the switch SW ₄ or SW _5, it can be switched to 5 stages, the switch SW
₄ in the direction the cleaning water is increased and manipulating, also is the amount of wash water and operate the switch SW ₅ can be set in stages in the direction to decrease. In this case switch SW ₄
Alternatively, the set value stored in the control circuit 7 so that the set value is sequentially increased from the current value to the maximum value or decreased sequentially to the minimum value every time a predetermined time elapses while the SW ₅ is pressed. Is updated, and the set value at that time is stored when the operation is canceled. Further, the display elements L ₁ ... According to the set water amount are turned on through the drive circuit 16. This set washing water amount is set within the range of the rating of the pump motor 1.

Thus anal irrigation by the operation of the anus washing switch SW ₁ in is performed by the amount of water within the above range.

Here the wash water is increased when it is desired to shorten the cleaning time, it is preferable to operate the increased switch SW _6. When the increase switch SW ₆ is pressed, the control circuit 7 outputs, for example, one of the rated values.
A control signal for driving the pump motor 1 at 20% is output to the drive circuit 8. The drive circuit 8 drives the pump motor 1 at 120% of the rating based on the control signal. The drive circuit 7 is operated when the stop switch SW ₇ is pressed or when the increase switch SW ₆ is pressed.
The control signal is continuously output to the drive circuit 8 so that the drive of the pump motor 1 is continued until the push operation of the is released. That is, 10% driving is performed during the period when the user is operating. In this case, the amount of water absorbed into the hot water tank 4 by the pump 2 increases, and the amount of hot water pushed out increases accordingly. By operating the increase switch SW _6, the control circuit 7 switches the flow path of the electromagnetic valve 5 to the anal cleaning jet nozzle 6, so that the anus is cleaned with the increased amount of cleaning water, and the cleaning time can be shortened accordingly. It is. And for driving the pump motor 1 only during press operation period of increasing switch SW ₆ of the user, the operating time of the pump motor 1 can be minimized.

Now, after the washing, if it is desired to dry the wet anus, the drying switch SW ₃ may be pressed and operated. When the switch SW ₃ is pressed, the control circuit 7 drives the fan motor 13 through the driving circuit 14. At the same time, power is supplied to the hot air heater 11 through the power supply control circuit 12 to heat the air blown by the rotation of the fan motor 13 to generate hot air, and the local air is dried by the hot air. This drying period is set in advance by an internal timer of the control circuit 7, and the drying switch
The energization of the fan motor 13 and the hot air heater 11 is maintained until the drying period elapses from the time when the SW ₃ is pressed.

When performing bidet washing may be operating the bidet washing switch SW _2, the control circuit 7 so that the washing water that is set in advance suitable for bidet washing in this case the drive circuit 8
, The pump valve 1 is driven for a certain time, and at the same time, the electromagnetic valve 5 is switched to the side of a jet nozzle for cleaning bidet (not shown), and the hot water pushed out by the hot water tank 4 is jetted out of the nozzle (see FIG. (Not shown).

Note The above and in anal washing, may be operated to stop switch SW ₇ if you want to stop on the way to operation in a bidet, the control circuit 7 If this operation is to stop the operation immediately.

[Effects of the Invention] The present invention provides a drive circuit for driving a pump motor for driving a pump for pressurizing hot water stored in a hot water tank and ejecting the hot water from an ejection nozzle. A switch for issuing a command to drive the pump motor, and a control circuit for controlling the drive circuit based on the command from the operation of the switch to maintain the drive of the pump motor exceeding a certain rating or more during the operation of the switch. Therefore, the operation of the switch can set the drive of the pump motor to a value higher than the rated value. Therefore, the amount of washing water can be increased without using a large pump motor, and the apparatus can be prevented from being enlarged. If the user wants to increase the amount of washing water, he only has to operate the switch, and this increase period is only during the operation of the switch. In addition to shortening the time, the period during which the pump motor is driven above the rating is shortened, which has the effect of reducing the effect on the life of the pump motor, and repeating the switch operation and non-operation. Accordingly, the washing water amount can be intermittently changed to give a stimulus to the washing part, and there is an effect that a massage effect is expected.
