DETAILED DESCRIPTION OF THE INVENTION

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 small-sized or menstrual periods.

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. 7, 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. From the branch point 4, through a heating means 7 constituted by a hot water tank 6 provided with a heater 5 and a tapping pipe 8, a hot water inlet 11 of a mixing valve 10 provided with an electric driving means 9 comprising a motor
And a path from the branch point 4 to the water inlet 13 of the mixing valve 10 via the bypass pipe 12. The hot water tank 6 has a hot water temperature detector 14 comprising a thermistor for detecting the temperature of hot water heated by the heater 5 of the heating means 7.
And a heating temperature control means 15 for controlling the input of the heater 5 to a preset temperature while feeding back the signal of the hot water temperature detector 14. A mixing temperature detector 18 for detecting the temperature of the hot water is provided in a hot water pipe 17 for sending hot water in which the hot water of the tapping pipe 8 and the water of the bypass pipe 12 are mixed by the mixing valve 10 to the flow control valve 16. Mixing temperature control means 20 for controlling the mixing valve 10 by comparing the temperature set by the setting device 24 for setting the temperature of the hot and cold water flowing through 17 with the temperature detected by the mixed hot water temperature detector 18 is provided. 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 the setting device 24. The setting device 24 includes an anal washing switch 25, a bidet washing switch 26, a stop switch 27, a temperature setting switch 28, and a flow setting switch 2.
9 are provided. The operation of the above configuration will be described. For example, when the user presses the anal washing switch 25 provided on the setting device 24, the controller 30 causes the flow control valve 16
The on-off valve 3 opens the flow path, the flow control valve 16 opens the flow path on the side of the discharge nozzle 12 to the valve opening corresponding to the flow rate set by the flow rate setting switch 29, and the discharge nozzle 12 is protruded by water pressure. A predetermined flow rate for cleaning flows. At this time, the hot water previously heated in the hot water tank 6 and the water passed through the bypass pipe 12 are mixed, and the temperature detected by the mixed hot water temperature detector 18 is set by the temperature setting switch 28 of the setting device 24. The mixing valve 10 adjusts the mixing ratio to reach the temperature. 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 anal washing is discharged.
Is stored by the bias of a built-in spring (not shown). When the bidet cleaning switch 26 is pressed, the discharge nozzle 23 for bidet cleaning protrudes, as in the case of anal cleaning,
Washing is performed. 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.

However, in the above-described conventional local cleaning device, when the on-off valve 3 is opened, the supply pressure is directly applied to the hot water tank 6, so that the supply pressure is applied to the hot water tank 6. It is necessary to have a structure that can withstand the above. Therefore, it is necessary to form a plurality of reinforcing ribs on the outside of the hot water tank 6 or use a high-strength material, but in this case, production costs, material costs, and the like increase. Further, since a relatively large amount of material is required, the weight becomes heavy and the assembling property is poor. 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, in order to ensure that the proper temperature can be obtained at any time, it is necessary to keep the temperature constantly during the non-use time, and if the temperature is high, the heat loss naturally increases and the electricity bill increases. I will. In addition, when storing and using the actually used hot water temperature, a sufficient amount of hot water is required to perform local cleaning with a sufficient amount of hot water, so that the capacity of the hot water tank 6 cannot be reduced.

In order to solve the above-mentioned problems, according to the first aspect of the present invention, there is provided a tank for storing water from a water supply source, a heating means for heating the inside of the tank, Mixing means for mixing the hot water heated by the heating means and water supplied directly or indirectly from a water supply source, a cleaning nozzle for jetting the mixed hot water mixed by the mixing means, and water supply to the nozzle In a local cleaning device having a flow rate adjusting means for adjusting the amount, when the flow rate is adjusted to a large flow rate by the flow rate adjusting means, the control means for controlling the mixing means so as to lower the temperature of the supply hot water and supply the water is provided.
