[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water discharge technique of a sanitary washing device for cleaning a local part of a human body such as an anus, and more particularly to a function of intermittent water discharge by pressurizing hot water and repeatedly discharging and stopping water. Water discharge device of a sanitary washing device.

[0002]

2. Description of the Related Art Conventionally, a sanitary washing device for jetting hot water to a local area for washing has been provided with a massage function for variably discharging the hot water, but this type of device generally changes the flow rate of hot water by changing the flow rate of hot water. Normally controlled by strength
Can not obtain a water force exceeding the water pressure of the water supply, and can obtain a sudden change in the washing hot water discharged from the nozzle
As there was no massage, there was dissatisfaction with the massage effect.

[0003]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above problems, and has a novel structure that can obtain a strong massage effect of cleaning hot water discharged from a nozzle with a simple structure. It is an object of the present invention to provide a water discharging device of the device.

[0004]

In order to achieve the above object, a display device according to the present invention comprises: a hot water tank provided with a heating device for heating water from a water supply to a predetermined temperature; In a sanitary washing device having a nozzle body for jetting stored hot water toward a local portion from a washing water jetting hole at a tip thereof, a predetermined amount of water in the hot water tank is supplied to a washing water supply path at a preceding stage of the hot water tank. A first electromagnetic valve that is controlled to be opened and closed by a central control circuit so as to maintain the water level, and a second electromagnetic valve that is intermittently controlled to be opened and closed at predetermined time intervals by a central control circuit in a cleaning water supply path immediately before the nozzle body. A valve is provided, and a pressurizing pump for maintaining a secondary pressure at a predetermined water pressure is provided in a washing water supply path between the second solenoid valve and the hot water tank, and an operation switch input to the central control circuit is provided. of The No.択信, usually of the water discharge is selected
When this is done, the central control circuit drives the pressure pump.
Water is discharged by the water pressure of the water supply without moving, and intermittent water discharge is selected.
When selected, the central control circuit activates the pressure pump.
The gist of the invention is to control the opening and closing of the second electromagnetic valve while driving the nozzle, and to discharge the washing water from the nozzle body finely and intermittently at a predetermined speed.

[0005]

When the normal water discharge is selected by the selection signal from the operation switch input to the central control circuit, the normal water discharge is selected.
Clean water without driving the pressure pump by the central control circuit
Water is discharged by road pressure and intermittent water discharge is selected.
In this case, the central control circuit drives the second solenoid valve to open and close while driving the pressurizing pump to discharge the washing water finely and intermittently from the nozzle body at a predetermined speed. .

[0006] In other words, the cleaning warm water to be discharged from the nozzle, place
Water is discharged intermittently by repeating water discharge and water stoppage at regular time intervals, and a powerful massage is performed. The second solenoid valve and the pressurizing pump are placed just before the nozzle body, and while the pressurizing pump is operated by the operation input from the operation switch,
Since the solenoid valve has a structure that repeats "ON" and "OFF", a sudden change in water discharge is performed, and a massage function such as tapping can be enhanced.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the water discharge device of the sanitary washing device according to the present invention will be described below with reference to the drawings. FIG. 1 shows a supply system for washing hot water, in which 1 is a first solenoid valve provided upstream of the hot water tank 2 and on the washing water supply side, and a pressure pump is provided downstream of the hot water tank 2. 3 through the second solenoid valve 4
And supplying the cleaning hot water heated by the hot water tank 2 to the cleaning water jetting nozzle device 5 arranged downstream of the second electromagnetic valve 4. , The pressurizing pump 3 and the second solenoid valve 4 are controlled to be “ON” and “OFF” by a hydraulic controller 7.

The nozzle device 5 for jetting washing water supports a nozzle body 8 having a discharge hole formed at the tip with respect to a cylinder 9 so as to be slidable in the front-rear direction, and a nozzle position displacement motor fixed to the cylinder 9. Numeral 10 allows the nozzle body to be moved to a storage position, an anal cleaning position, or a bidet cleaning position.

The hot water tank 2 has a structure in which a water drainage stopper 11 is provided at the bottom and is sealed by a lid member 12.
Water supply pipe 13 and pressurizing pump 3 communicating with the first solenoid valve 1
It is provided with a discharge port 14 provided with a check valve for preventing the hot water backflow communicating with. Then, a heater 15 for heating the washing water is introduced into the hot water tank 2,
Water temperature sensor 16 for detecting the temperature of water in hot water tank 2
And the heater 15 is turned “ON” by the temperature controller 17 in response to a signal input from the water temperature sensor 16.
It is configured to perform “OFF” control.

The operation unit 6 input to the water pressure controller 7 includes a cleaning switch 61 and a massage cleaning switch 6.
2 are provided, and the water pressure controller 7, the first solenoid valve 1, the pressurizing pump 3, and the second solenoid valve 4 are configured to be controlled via drivers 71, 72, and 73, respectively.

The first solenoid valve 1 and the second solenoid valve 4
Can be a diaphragm type or a direct acting type.

In the water discharging device of the sanitary washing device having the above structure, the first electromagnetic valve 1 and the second electromagnetic valve 4 are opened by operating the cleaning switch 61 of the operation unit 6 to perform a normal water discharging operation from the nozzle body 8. . When "massage" is input from the massage washing switch 62 of the operation unit 6 during the normal water discharging operation, the pressurizing pump 3 is operated, and the primary water pressure of the second solenoid valve 4 is maintained at a high pressure. Then, the second solenoid valve 4 is turned “ON” and “OFF” by the output of the water pressure controller 7.
Is performed repeatedly, and the water discharged from the nozzle body 8 is rapidly changed (intermittent water discharge), and the cleaning water is finely dispersed at a predetermined speed.
Thus, the ink is intermittently discharged.

[0013]

[Effect of the Invention] The water discharge device of the sanitary washing device according to the present invention has the second solenoid valve and the pressurizing pump immediately before the nozzle body as described above, and operates the pressurizing pump by an operation input from the operation switch. Meanwhile, the solenoid valve “ON”, “OF”
F "is repeated, and a rapid change in water discharge is performed. Therefore, intermittent water discharge can be performed by the pressurizing pump at a higher pressure than during normal water discharge. Further, by providing the second solenoid valve in front of the nozzle body, since it is possible to prevent the escape of pressure due to the expansion change of the hot water tank and pipes, strong <br/> force as tapping by intermittent water discharge It has a feature that a great massage effect can be achieved , and the effect obtained by implementing the present invention is extremely large.
