Problems solved by technology

[0012] However, in the known Figure 31 In the flow velocity sensor of , since the washing water for rotating the impeller 206 flows straight from the inflow path 202 to the outflow path 203, the fluid force for rotating the impeller is insufficient
Therefore, at lower flow velocities, the impeller 206 may not rotate, or very unfavorably, erratically rotate
At the same time, if the air bubbles adhere to the impeller 206 in some form or other, the air bubbles are combined at the center of rotation of the impeller 206 due to the centrifugal force generated by the rotation of the impeller 206, and there is a problem that it is difficult to move outward. Air bubbles are discharged, and the rotation of the impeller 206 becomes unstable, thus causing a decrease in the accuracy of detecting the flow velocity
[0013] At the same time, in Figure 32 In the shown conventional personal privates washing device, since power is always supplied to the heater 211 in order to maintain the temperature of the washing water in the hot water storage tank 21, the loss of energy consumption is caused by heat dissipation.
In addition, since the air dissolved in the water in the hot water storage tank 212 may appear with air bubbles when heated, and the air bubbles flow into the flow rate sensor 201, the detected flow rate value has a large error due to the above-mentioned problem.

[0056] figure 1 Shown is the personal privates washing device according to the first embodiment of the present invention. exist figure 1 In, the water supplied from the water supply pipe 8 passes through a main solenoid valve 9, a motor-driven flow control valve 10 for adjusting the amount of washing water, and a flow velocity sensor as a flow detection means for detecting the flow and velocity of the washing water. 11 enters an instant heating type water heater 12 (ie, a heating device that continuously heats water to the current temperature as it flows, as described in "Background Art"). Both the main solenoid valve 9 and the flow control valve 10 are used as water supply control devices. The water heater 12 is provided with a high limit switch 13 that cuts off the power supply to the water heater 12 once it detects that the temperature of the water heater 12 itself rises abnormally, and an air detection thermistor 14 for detecting the presence of water in the water heat...

[0084] Figure 8 , Figure 9 and Figure 10 They are respectively a perspective view, a cross-sectional view and a longitudinal sectional view of the water heater used in the private parts washing device according to the second embodiment of the present invention. exist Figure 8-10 Among them, the water heater main body 61 is composed of a ceramic heater 62 and a pair of metal heat exchanging parts 64 which are flat plate type heating means and are arranged substantially in the central part. A silicone agent 63 is applied on one surface of the heat exchange portion 64 in contact with the ceramic heater 62 in order to improve heat conduction therebetween so that the ceramic heater 62 is sandwiched between the heat exchange portions 64 . In the ceramic heater 62, a metal heating element 65 generating Joule heat by supplying electric energy is clamped between a pair of rectangular ceramic plates 66 made of alumina or the like, and then integrally fired. Wires 67 are connecte...

[0089] Figure 7 is a perspective view of a water heater used in a personal privates washing device according to a third embodiment of the present invention. and Figure 8-10 Components with the same designation as in Figure 8-10 Corresponds to the constituent elements in , so a detailed description is omitted. exist Figure 11 Among them, a pair of heat exchanging parts 64 are made of resin material, and meandering water channel 69 is opened on one end surface of each heat exchanging part 64, and this heat exchanging part 64 is adjacent to ceramic heater 62, makes water directly contact with ceramic heater 62 contacts. In order to close the meandering water channel 69, an O-ring is provided in each heat exchanger 64, so that water will not leak from the meandering water channel 69.

[0090] Through the above-mentioned device, when water is introduced into the water inlet 70 and electric power is supplied to the ceramic heater 62, the ceramic heater 62 is made of alumina...

Abstract

A bidet includes an water heater 12 to which a water supply pipe 8 and a hot water pipe 15 are connected; water supply control devices (9,10) for controlling the clean water to the water heater 12; a discharger for discharging the clean water with the moderate temperature heated by the water heater 12 connected with the hot water pipe 15; wherein the water heater 12 can heat the clean water supplied by the water supply pipe 8 to the moderate temperature during the flowing process of the clean water and flows into the hot water pipe 15. Through heating by the heating device when the water or the hot water is detected by the flow rate monitoring unit, the safety and the reliability can be ensured when supplying a plurality of air and water.

Description

technical field [0001] The invention relates to a human lower body washing device for washing the human body with hot water. Background technique [0002] This traditional human lower body cleaning device is as disclosed in Japanese Patent Publication No. 5-33377 (1993) Figure 28 shown. Figure 28 is a schematic diagram showing a washing water supply system in which the water supply pipe 152 is connected to the upstream side of the pump 151 and the air mixing portion 153 is mixed to the downstream side of the pump 151 . The air mixing section 153 includes a cylindrical water suction head 154 made of ceramics so that air sent from a compressor 155 is mixed into water in the water suction head 154 . With this arrangement, the wash water supplied from the water supply pipe 152 is pressurized by the pump 151 and entered into the air mixing portion 153 . In the air mixing part 153, the air supplied from the compressor 155 is divided into fine parts to flow into washing water. ...
