DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local cleaning apparatus for cleaning an anus after stool and for cleaning a local part of a woman during a small or menstrual period, and in particular, sprays cleaning water containing bubbles from a nozzle. The present invention relates to a local cleaning device.

[0002]

2. Description of the Related Art Conventionally, a local cleaning apparatus of this kind has been disclosed in, for example, Japanese Patent Application Laid-Open No. 9-195364.
Hereinafter, a conventional local cleaning apparatus will be described with reference to the drawings.

In FIG. 1B, water supplied by a water supply pipe 1 reaches a branch point 4 via a pressure reducing means 2 and an on-off valve 3 for opening and closing a flow path. A path from the branch point 4 to a hot water inlet 11 of a mixing valve 10 provided with an electric driving means 9 comprising a motor, through a heating means 7 constituted by a hot water tank 6 provided with a heater 5 and a tapping pipe 8. And the bypass pipe 12 from the branch point 20
Through the water inlet 13 of the mixing valve 10. The hot water tank 6 is provided with a hot water temperature detector 14 composed of a thermistor for detecting the temperature of the hot water heated by the heater 5 of the heating means 7, and while feeding back the signal of the hot water temperature detector 14, Heating temperature control means 15 for controlling the input of heater 5 to a preset temperature
Is provided. In addition, hot water of tapping pipe 8 and bypass pipe 12
A hot water pipe 17 for sending hot water in which the water is mixed by the mixing valve 10 to a flow control valve 16 is provided with a mixing temperature detector 18 for detecting the hot water temperature, and a setting device for setting the temperature of hot and cold water flowing through the hot water pipe 17. Set temperature by 19 and mixed hot water temperature detector 18
A mixing temperature control means 20 is provided for controlling the mixing valve 10 by comparing the temperatures detected by. Further, discharge nozzles 22 and 23 are provided at the end of the hot water pipe 17 via a flow control valve 16 provided with an electric drive means 21 composed of a motor. The discharge nozzles 22 and 23 have a configuration in which 22 is a nozzle for cleaning the anus and 23 is a nozzle for cleaning the bidet, and the switching is performed by the flow control valve 16.

The operation of the local cleaning device is performed by a setting device 24. The setter 24 includes an anal washing switch 25,
A bidet cleaning switch 26, a stop switch 27, a temperature setting switch 28, and a flow rate setting switch 29 are provided.
In the above configuration, the operation will be described. For example, when the user presses the anal cleaning switch 25 provided on the setting device 24, the flow control valve 16 and the opening / closing valve 3 are opened by the controller 30 to open the flow path. The flow control valve 16 opens the flow path on the side of the discharge nozzle 12 at a valve opening corresponding to the flow rate set at 29, the discharge nozzle 12 is protruded by water pressure, and a predetermined flow rate for cleaning flows.

At this time, the hot water previously heated in the hot water tank 6 and the water having passed through the bypass pipe 12 are mixed, and the temperature detected by the mixed hot water temperature detector 18 is set by a temperature setting switch 28 of the setter 24. The mixing valve 10 adjusts the mixing ratio so that the temperature set in the step (1) is reached. When cleaning is completed, the stop switch 27 is pressed to close the on-off valve 3 and stop water, and the flow control valve 16 is also brought to the stop position. When the stop switch 27 is pressed and the supply of the washing water is stopped, the discharge nozzle 22 for anus washing is stored by the bias of a built-in spring (not shown).

[0006] When the bidet cleaning switch 26 is pressed, the discharge nozzle 23 for bidet cleaning protrudes, and cleaning is performed in the same manner as in the case of anal cleaning. Therefore, the hot water heated from the water supply pipe 1 provided with the on-off valve 3 via the heating means 7 and the water from the water supply pipe 1 through the bypass pipe 12 flow into the mixing valve 10 by the supply water pressure, respectively. At 10, the hot water is adjusted to the appropriate temperature and supplied to each nozzle.

[0007]

However, in the above-described conventional local cleaning apparatus, a mixing valve is required to obtain hot water, which increases the cost.
Further, in the case of mixing and supplying an appropriate temperature, hot water having a higher temperature than the actually used hot water must be stored in the hot water tank 6. However, the use time of the toilet is very short as compared with the non-use time. Nevertheless, to be able to get the right temperature at any time,
The non-use time must always be kept warm, and the higher the heat retention temperature, the greater the heat dissipation loss naturally,
Electricity bills increase. Further, since water flows into the hot water tank 6 even during use, it is necessary to provide a baffle plate or the like so that the flowing water does not mix with the heated hot water in the hot water tank 6, and the internal mechanism is complicated. Had been transformed.

As a solution to the above, Japanese Patent Laid-Open No.
There is an apparatus disclosed in Japanese Patent No. 18390, but this apparatus uses an air pump to forcibly send air into the hot water to reduce the amount of water used, and uses an instantaneous heat exchanger as a hot water source. Eliminate heat loss during use hours,
The goal was to eliminate energy loss. But,
As the amount of water was reduced, the feeling of use was reduced, and the user was nervous about whether or not washing was sufficient.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a heating means for heating water from a water supply source and supplying hot water heated by the heating means to a cleaning nozzle. Hot water supply means, water supply means for supplying water from a water supply source to the cleaning nozzle independently of the hot water supply means, and hot water supplied from the hot water supply means to the cleaning nozzle for the local area. Equipped with a hot water discharge port for spouting and a water discharge port for spouting water supplied from the water supply means toward a local area, so that a mixing valve is not required and the heating means has a small capacity. And compactness can be achieved.

In addition to the above, when the heating means is an instantaneous heat exchanger, heat loss during non-use time can be eliminated and energy loss can be suppressed. Also,
By providing the water supply means with a water amount adjusting function for adjusting the amount of water, it is possible to adjust the bodily sensation to the user and to provide a user with a suitable washing feeling. Further, by providing the water supply means with an intermittent supply function of intermittently supplying water, various washing feelings can be obtained by alternately repeating hot water and cold water. Further, the intermittent cycle is 5
By setting the frequency to ２０20 Hz, the rectal pressure is increased, the anal sphincter muscle is relaxed, and a defecation promoting effect can be obtained. This effect is further enhanced by setting the intermittent cycle to 10 to 15 Hz.
