Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sanitary cleaning device that can perform hygienic and comfortable treatment of private parts by washing the private parts with warm water, for example, after using the toilet.

[Conventional technology]

Since such sanitary cleaning equipment cleans private parts that are particularly sensitive to temperature, hot water for cleaning at an appropriate temperature is always supplied from the beginning to the end of use, and the temperature does not change much even when used for a long time. required. However, in the past, the water used for cleaning was heated in a tank using a heating unit such as a sheathed heater, and a temperature sensing unit such as a thermostat was installed in the tank to adjust the temperature of the hot water for cleaning. Since we were using a so-called tank-type water supply heating device, it was necessary to make many openings in the tank, such as a water inlet, a hot water outlet, a temperature detection unit installation port, a heating unit installation port, etc. In addition, the sealing portion of the opening is prone to failure. Moreover, depending on how the temperature sensor is installed, the temperature of the hot water in the tank cannot be detected accurately.
Moreover, its reactivity is poor, and if the hot water in the tank is used, especially when used for a long time, the temperature may drop suddenly or the temperature may change greatly, causing discomfort. It was not possible to fully satisfy the requirements of

[Problem to be solved by the invention]

In addition, it is necessary to appropriately set and control not only the temperature of the washing water, but also the temperature of warm air from a hot air device installed for drying purposes, the temperature of the heated toilet seat, and the like. However, in the past, there has been a tendency to focus only on temperature control of flush water, and comprehensively setting a comfortable temperature including warm air and toilet seat temperature has not yet been adopted.

〔Example〕

Hereinafter, features of the present invention will be specifically explained with reference to embodiments shown in the drawings.

In Figures 1 and 2, 1 is the toilet bowl, 2 is the toilet cleaning tank installed at the rear end of the toilet bowl, and A is the water supply heating device installed at the rear of the toilet bowl 1 and straddling the toilet bowl 1 using the mounting bracket 3. This is a sanitary cleaning device body composed of A-1 and a hot air device A-2, and the toilet seat 4 and toilet lid 5 of a heated toilet seat A-3 are pivotally connected to the sanitary cleaning device body A so that they can be opened and closed. ing.

3 to 14 show the structure of the sanitary cleaning device main body A. The case 6 of the sanitary cleaning device main body A is formed into a substantially L-shape in plan, and is made of a synthetic resin such as ABS resin. It consists of a back plate 6b that can be opened and closed with respect to the casing 6a, and a substrate 6c such as a pressed stainless steel plate.

Then, one end of the connecting fitting 7 attached to the back side of the lower side of the case 6 is connected to a water supply source via a branch tap 8, and the other end is connected to one end of a water conduit 9 made of, for example, a copper pipe within the case 6. The other end of this water conduit 9 is connected to the heat transfer section 13 through an on-off valve 10 that is manually opened and closed, a flow rate adjustment valve 11 that serves both flow rate adjustment and pressure adjustment, and a distribution valve 12. It is connected to the water supply side connecting pipe 19-1 of the pipe 18-1. The branch tap 8 is connected, for example, to a water supply pipe 40 that supplies water to a ball tap (not shown) of the toilet cleaning tank 2.

The opening/closing valve 10 is configured to be opened and closed by manual operation, and its opening/closing handle 10a is provided on an operating part D provided at the front of the upper surface on the side of the case 6 so that it can be easily operated while sitting on the toilet seat 4. There is. That is, the valve housing 10b is attached and fixed to the case 6, and the opening/closing handle 10a protrudes from the casing 6a. Further, the operating portion D is covered with a cover 6f that can be opened and closed.

The flow rate adjustment valve 11 includes a flow rate adjustment knob 11a, and the flow rate of water supplied to the distribution valve 12 is increased or decreased by rotating the flow rate adjustment knob 11a.
Thereafter, the flow rate and pressure on the outflow side are kept constant regardless of fluctuations in water pressure on the inflow side.

The distribution valve 12 has an inlet 12a that communicates with the flow rate adjustment valve 11, a first outlet 12b that communicates with a heat transfer section 13, which will be described later, and a second outlet that communicates with a vacuum breaker valve 15'.
an outlet 12c, and this first outlet 12
b and an adjustment knob 12d that changes the ratio of the flow rate flowing out from the second outlet 12c. This adjustment knob projects outward from the casing 6a and is provided at the upper center of the side surface of the case 6.

By rotating this adjustment knob 12d, the ratio of the flow rates flowing out from the first outlet 12b and the second outlet c can be changed without changing the flow rate flowing in from the inlet 12a.

Note that this distribution valve 12 is used together with the flow rate adjustment valve 11 as a countermeasure against the insensitive amount of water in a water meter. Thereafter, the distribution valve 12 passes through a heat transfer section 13, an intake valve 14, and a vacuum breaker valve 15, which will be described later, to a cleaning water path that connects to a spout 28f for local cleaning of the jet section B, and a vacuum breaker valve 15' to the jet section. The excess water is distributed to a surplus water path that connects to the B discharge port 27f.

That is, the water flowing out from the first outlet 12b of the distribution valve 12 flows into the heat transfer section 13, is heated by the heating section a-1 that heats the heat transfer section 13 from the outside, and is ejected as hot water for private washing. The water that reaches part B and flows out from the second outlet 12c does not pass through the heat transfer part 13 and reaches the spouting part B via the vacuum breaker valve 15' as surplus water.

In addition, in this embodiment, the flow rate flowing into the feed water heating device A-1 is set by the flow rate adjustment valve 11, and the flow rate flowing into the feed water heating device A-1 is set by the flow rate adjustment valve 11.
The flow rate of hot water spouted from the spout part B is adjusted by adjusting the ratio of cleaning water and surplus water, but on the contrary, the ratio of the distribution valve 12 is kept constant and the flow rate of the hot water is adjusted. You can also change the flow rate of hot water. Furthermore, if measures against the insensitive water amount are unnecessary, the flow rate adjustment valve 11 and the distribution valve 12 are not necessarily necessary, and the flow rate of hot water may be adjusted by changing the opening degree of the on-off valve 10.

15 to 18 show a first embodiment of the heat transfer section 13, in which 16 is a heat conduction plate that closely contacts the planar heating element 17 constituting the heating section a-1, and 18-
1, 18-2... are large diameter heat conduction tubes constituting two or more large diameter tubular parts b-1 of the heat transfer section 13, and the heat conduction plate 16 and the heat conduction tubes 18-1... are wires. The plurality of heat conduction tubes 18-1 are fixed in the vertical direction by close contact means (for example, brazing or the like) while maintaining contact.

19-1, 19-2... constitute a small diameter tubular portion b-2 of the heat transfer section 13, and a plurality of heat transfer tubes 18-1, 18
-2... A thin connecting pipe that connects each other, 19-1
is the water supply side, that is, the first outlet 12 of the distribution valve 12
b, and 19-11 communicates with the intake valve 14 on the water discharge side. The cross section of each heat conduction tube 18-1... is as shown in FIGS. 17 and 18. That is, the upper ends of the heat conduction tubes 18-1 are narrowed, and the connecting tubes 19-1 are inserted into the heat conduction tubes 18-1 from the upper ends, with long inflow sides and short outflow sides. Moreover, it is fixed at the upper end by means such as brazing to prevent water leakage.
For this heat conduction tube 18-1..., the planar heating element 17 constituting the heating part a-1 that heats from the outside is the first
As shown in FIG. 9, from the outside to the inside, there is a skin resin layer 23a made of polyester or the like, a heat generating conductor 23b such as an aluminum foil circuit, an intermediate resin layer 23c made of polyester, a lower resin layer 23d, and a release paper 23.
The adhesive layer 23e to which f is pasted is successively layered into a flat plate and integrally formed. Then, the release paper 23f of the planar heating element 17 is peeled off, and the adhesive layer 23e is attached to the heat conductive plate 16 such as a copper plate, which is fixed to the outside of the heat conductive tube 18-1 by brazing or the like.
It is attached with Therefore, the water that has flowed into the heat transfer section 13 is efficiently heated by the heating section a-1 while flowing through the plurality of large diameter tubular sections b-1 made up of the heat transfer tubes 18-1, 18-2... The water becomes warm water at an appropriate temperature, flows out from the final connecting pipe 19-11, and reaches the spouting part B. In addition, a temperature detection plate 24 is attached to the outer wall of the heat transfer pipe on the discharge side by brazing or the like, with the thermistor 22 having a negative characteristic constituting the temperature detection part d-1 that detects the temperature of hot water separated from the heating part a-1. installed on. Then, based on the detection by the temperature detection plate d-1, the heating part a-1, that is, the planar heating element 1
A temperature control section e-1 that controls the power supply to the case 6 and automatically adjusts the temperature is separated from the heat transfer section 13 and installed in the case 6.
It is housed in a control box E provided inside. Note that the heating section a-1 may be a sheathed heater or the like. Further, as the temperature control section d-1, a thermistor with positive characteristics, a platinum thermometer, a thermocouple, etc. can also be used. Further, F-W is a temperature fuse similarly attached to the heat conduction plate 24 of the heat conduction pipe 18-9 on the discharge side.

Since the heat transfer tubes 18-1, 18-2... are arranged vertically, and the inner diameter of the connecting tubes 19-1, 19-2... is small, the air in front of the flowing water in the direction of water flow is directed vertically downward. Even in this case, the air is always pushed out first. The supply water entering from the connecting pipe 19-1 first fills the heat conducting pipe 18-1, and while being sent into the pipe, it passes through the connecting pipe 19-2 and fills the heat conducting pipe 18-2. In other words, a short tube serves to send all the air in the tube to the next tube.

By repeating this process, the connecting pipe 19-1 is finally
When water is discharged from the heat transfer section 13, the air inside the heat transfer section 13 is also discharged at the same time, so that no air remains in the heat transfer tubes 18-1 and the connecting tubes 19-1.
Furthermore, even if air gets mixed into the water supply, it will be discharged together with the spouted water in the order described above. Heat transfer part 1
The water flowing into the heat transfer section 13 is heated by the heating section a-1 that heats it from the outside while flowing in the heat transfer section 13, so the flow path is longer than in the tank type, and the heat transfer area is greatly increased. be able to.

In the heat transfer section 13 of this embodiment, the inner surface area (heat transfer area) and volume of the heat transfer tube constituting the large diameter tubular section b-1 used therein have a considerable influence on the heating characteristics and cost. ing. Now, as a heating characteristic, 0℃
When the conditions are set such that hot water at a temperature of 36℃ to 40℃ is spouted for more than 1 minute at a flow rate of 400 to 600c.c./min after water discharge starts at room temperature and water temperature of , the heat transfer area is approximately
The above conditions are satisfied if the area is 1000 cm ² , the volume is about 600 c.c., and the calorific value of the planar heating element 17 is about 800 W.

When compared with a structure in which a plurality of large-diameter tubular portions b-1 are disposed laterally, no air remains in the heat transfer portion 13, and the heating characteristics of hot water are improved. Also,
Since the heat transfer section 13 is composed of a plurality of large diameter tubular sections b-1 and small diameter tubular sections b-2, the heat transfer section can be made more compact than when the heat transfer section is composed of tubular sections of the same diameter. , and in this embodiment, the large diameter tubular portion b-
Since the joint parts of the heat transfer part 1 and the small diameter tubular part b-2 are concentrated at the upper end, the joining work becomes easy and the manufacturing cost of the heat transfer part becomes very low.

Furthermore, as shown in FIG. 17, the first heat transfer tube 1
A drain plug 20 is provided at the lower part of the valve 8-1.
When the water drain valve 20 is opened, the water stored in the heat transfer part 13 is discharged due to a siphon phenomenon.
The water inside can be easily drained.

Therefore, water does not leak from the device during transportation, and it is very easy to drain water when not in use in cold regions, and there is no risk of water freezing and destroying the device.

FIG. 24 shows that a sheathed heater is inserted into a sheathed heater insertion hole 16b in a thick heat conduction plate 16a, and two or more large diameter heat conduction tubes are attached to the outer periphery of both sides of the heat conduction plate 16a by brazing or the like. 18c are arranged in the horizontal direction, and each heat conduction tube 18c
The left and right ends of the tubes are alternately connected by small-diameter connecting pipes 19c. Furthermore, in FIG. 25, instead of the sheathed heater, a planar heating element 17a is sandwiched between two heat conduction plates 16, and two or more heat conduction tubes 18c are arranged on the heat conduction plates 16. This sheet heating element 17a has an adhesive layer 23e on one side of the sheet heating element 17 explained in FIG. It has become.

a and the outlet 14b are in communication. Therefore, when hot water flows, the valve body 14f is pushed up by the water pressure of the hot water flowing in from the inlet 14a, and the air valve 1
4d closes and the flow of water stops, the valve body 14f descends due to its own weight, the air valve 14d opens, the outlet 14b communicates with the air port 14c, the vacuum state is broken, and the water valve 14e closes. Due to the presence of the narrow groove 14h drilled in the seat 14g, the inlet 14a communicates with the air port 14c, and each heat transfer tube 18-1... and connecting tube 19 of the heat transfer section 13 connected to the inlet 14a side -1... vacuum state is destroyed. Therefore,
Water in the heat transfer section 13 can be easily drained by simply opening the water drain plug 20 described above. In this embodiment, the main body of the intake valve 14 is made of ABS resin, and the valve body 14f
is made of a synthetic resin with low heat capacity and thermal conductivity, such as polyacetal resin, but it may also be made of metal.

A water valve 15e that opens and closes the gap is provided on the upper and lower surfaces of the valve body 15f, and when hot water flows, the inlet 1
The water pressure of 5a pushes up the valve body 15f and opens the water valve 15e. The inlet 15a and the outlet 15b communicate with each other, and at the same time the air valve 15d closes. When the flow of water stops, the valve body 15f descends due to its own weight. At the same time as the water valve 15e is closed, the air valve 15d opens, the outlet 15b communicates with the air hole 15c, the vacuum state is broken, and backflow of water is prevented. The vacuum breaker valve 15' has the same structure as the vacuum breaker valve 15, so a description thereof will be omitted. In this embodiment, the main bodies of the vacuum breaker valves 15, 15' are made of ABS resin, and the valve body 15f is made of a synthetic resin with low heat capacity and thermal conductivity, such as polyacetal resin. As shown in FIG. 3, the spouting portion B is installed in a substantially central portion of the case 6 in an oblique manner toward the inside of the toilet bowl 1.

The details are shown in FIGS. 30 to 34.

In this embodiment, the jetting part B is composed of a jetting part main body 27 and a nozzle 28 that is extendable and retractable with respect to the jetting part main body 27. The main body 27 and the nozzle 28 are
It is made of synthetic resin such as ABS resin or polyacetal resin, and is plated if necessary. It may also be made of metal. The spout main body 27 is provided with a hot water supply port 27a and a surplus water supply port 27b,
The hot water supply port 27a is connected to the nozzle 2 through the inner cylinder 27c.
The surplus water supply port 27b communicates with the opening 28c opened on the upper surface of the tip of the spout body 27 and the inner cylinder 2.
7c, a piston portion 28 of the nozzle 28 that slides within the cylindrical chamber 27d.
The small hole 28b drilled in a connects the main body 27 and the nozzle 2.
Through the annular chamber 27e formed by the small diameter portion of 8,
A discharge hole 27 bored in the distal end surface of the spout main body 27
I am contacting f. The nozzle 28 is guided by a cylindrical chamber 27d and an inner cylinder 27c and slides inside the ejection part main body 27, and a pressure receiving plate 28j with a small hole 28i opened approximately in the center is located in a hollow chamber 28h at the tip thereof. will be placed.

is inserted and is prevented from coming off by a retaining ring 28k. This nozzle switching tube 28e
Ejection holes 28f are formed in the upper and lower side walls of the cylinder, respectively, so as to correspond to the openings 28c. One of the ejection holes 28f is provided with one hole with a slightly large diameter, and the other is provided with a plurality of relatively small diameter holes, and one of the ejection holes 28f can be selectively opened by switching the knob 28d. 28c, so that it is possible to obtain a desired ejection form such as a nozzle shape or a shower shape. In addition,
27g is a positioning stopper for the knob 28d, which protrudes from the case 6. This positioning stopper 27g also serves to prevent dirty water from splashing onto the nozzle switching tube 28e when the spout section B is not in use. Furthermore, 27h is a positioning ring that is attached to the tip of the main body 27 and acts to prevent the nozzle 28 from rotating. Further, the nozzle 28 is always biased by the coil spring 28g in the direction of being housed inside the ejection part main body 27, so that the nozzle 28 is housed in the case 6 in a normal state. Therefore, when hot water and surplus water are supplied to the hot water supply port 27a and surplus water supply port 27b, respectively, the pressure of the surplus water increases to the piston portion 2 of the nozzle 28.
At 8a, the pressure of hot water acts on the pressure receiving plate 28j, causing the nozzle 28 to protrude inward of the toilet bowl 1 against the elastic force of the coil spring 28g.
The hot water is supplied to the inner cylinder 27c and the hollow chamber 2 of the nozzle 28.
8h, the water passes through the small diameter 28i of the pressure receiving plate 28j and is jetted toward the local area from the desired jetting hole 28f of the nozzle switching cylinder 28e to wash the private area, and the excess water flows into the cylindrical chamber 27d, the small hole 28b, and the annular chamber. 27e and is discharged into the toilet bowl 1 from the discharge hole 27f. Next, when the supply of hot water and surplus water is stopped, the surplus water in the cylindrical chamber 27d flows through the small hole 28b and into the annular chamber 27.
e, the hot water is gradually discharged into the toilet bowl 1 from the discharge hole 27f, and the hot water in the hollow chamber 28h is discharged through the pressure receiving plate 2.
It is gradually discharged into the toilet bowl 1 through the small hole 28i of 8j, the opening 28c, and the spout hole 28f. Therefore nozzle 2
8 is contracted again by the elastic force of the coil spring 28g and is housed in the ejection part main body 27. Note that the ejection part B does not have to be telescopic as in this embodiment. Similarly, the discharge hole 27f does not have to be switchable. In addition, surplus water is used to expand and contract the nozzle 28 and is discharged from the discharge hole 27f of the spout main body 27 to the toilet bowl 1.
The surplus water may be directly discharged into the toilet bowl cleaning tank 2 without being used for expanding or contracting the nozzle 28 or for cleaning.

A and Rf-A are resistors, I-A is an IC, Tr-A is a transistor, L-A and Cd-A are a light emitting element and a light receiving element, and T-A is a triac. It constitutes a temperature detection section e-2.
Note that M is a motor that drives the fan 34b (corresponding to the reference number 34a in FIG. 40), and Rth-A is a hot air device A- installed near the hot air blowing section 33.
2, Rc-A is a variable resistance that constitutes the temperature setting section f-2 of hot air device A-2, and Rh-A is the resistance of the thermistor 32 with negative characteristics that constitutes the temperature detection section d-2 of hot air device A-2. -2, the resistance of the heating element such as the nichrome wire 36 that constitutes the heating section a-2, It consists of a temperature fuse. The temperature control section e-2 and temperature setting section f-2 of the hot air device A-2 are housed in the control box E together with those of the water supply heating device A-1 and the heated toilet seat A-3.

In addition, Sw-S is a switch that controls power supply to heated toilet seat A-3, and Sw-wA is a switch that controls power supply to heated toilet seat A-3.
This is a changeover switch that switches the supply of electricity to the circuits of the hot air device A-1 and the hot air device A-2. The changeover switch Sw-wA is
In this embodiment, an opening/closing handle 1 is provided on the operation part D in front of the upper surface of the case 6 on the side opposite to the switch Sw-S.
It is installed close to 0a, and the changeover switch Sw-
The push button 39 of wA protrudes from the case 6. The changeover switch Sw-wA, which switches the heating circuit of the feed water heating device A-1, the heating circuit of the hot air device A-2, and the power supply to the motor M, is an alternate type or momentary type single-pole double-throw push button switch, By operating the push button 39, the heating circuit of the water supply heating device A-1 or the hot air device A-
The heating circuit of No. 2 and the motor M are configured to be energized.

Note that L-1 is a power cord, and L-2 is an electric cord connecting control box E and heated toilet seat A-3.

This control action will be explained in accordance with the explanatory electric circuit diagram of FIG. 42 as follows.

When the power is on, hot water, warm air, or the toilet seat 4
As the temperature decreases, the resistance Rth of the thermistor increases, so the voltage at point A in the figure is lower than the voltage at point B, and the ICI that makes up the comparator operates, raising the voltage at point C (H state). Become. When ICI goes into the H state, the transistor Tr becomes conductive, the light emitting element L emits light, and the light receiving element cd receives the light, which reduces the resistance of the light receiving element Cd, triggering the triac T and making it conductive. , heating element
A current flows through Rh, heating the hot water, hot air, or the toilet seat 4.

When the temperature of hot water, hot air, or toilet seat 4 increases, the resistance Rth of the thermistor decreases, the voltage at point A becomes higher than the voltage at point B, and the ICI operates and the voltage at point C becomes lower (L state). . When ICI becomes L state, transistor Tr is cut off and light emitting element L
light is no longer emitted, the resistance of the light receiving element Cd increases, and the trigger T loses its trigger and enters the cutoff state, and the power supply to the heating element Rh is stopped.
Hot water, hot air, or heating to the toilet seat 4 is stopped. When adjusting the temperature of hot water, hot air, or the toilet seat 4, the temperature adjusting variable resistors RC, which are temperature setting units f-1, f-2, and f-3, are adjusted. That is, if the resistance of the variable resistor RC is increased, the voltage at point A will not become higher than point B unless the resistance Rth of the thermistor becomes smaller. In other words, the heating element Rh is energized until the temperature of the hot water, hot air, or toilet seat 4 becomes higher and the resistance Rth of the thermistor becomes smaller, and the voltage at point A becomes higher than the voltage at point B. Become. That is, the temperature is set to high temperature. Conversely, if the resistance of the variable resistor RC is reduced, the temperature can be set to a lower temperature. Note that the temperature control circuit is not limited to this embodiment and can be freely modified. Of course, the heating parts a-1, a-2,
The energization to a-3 may be controlled.

Therefore, when using the water supply heating device A-
1 and heated toilet seat A-3. Therefore,
Hot water and toilet seat have their own temperature detection parts d-1 and d.
-3 detects the temperature, and based on the temperature detection parts d-1, d-3, the temperature control circuits d-1,
d-3 controls energization to the heating parts a-1 and a-3, and the temperatures of the hot water and the toilet seat 4 are automatically maintained at appropriate temperatures. In this state, even if a person sits on the toilet seat 4 to relieve himself, he does not feel cold.

To wash your private parts with warm water while sitting on the toilet seat 4 after using the toilet, use the opening/closing handle 10a provided on the operating section D.
to open the on-off valve 10. When the on-off valve 10 is opened, a constant amount of heat is transferred from the water supply connection pipe 19-1 into the heat conduction pipe 18-1 of the feed water heating device A-1 through the branch tap 8, the on-off valve 10, the flow rate adjustment valve 11, and the distribution valve 12. A large amount of water is supplied, and as it flows through the heat conduction tubes 18-1, it is sufficiently heated and becomes hot water at an appropriate temperature.
As this water is supplied, hot water previously stored at an appropriate temperature in the heat transfer tubes 18-1 is pushed out from the discharge-side connecting tube 19-11, and flows through the intake valve 14 and the vacuum breaker valve 15 to the spout section B. The liquid is supplied and sprayed toward the private parts through the desired jetting holes 28f, thereby cleaning the parts. Therefore, the private parts can be washed with warm water at an appropriate temperature immediately after the start of use. Note that spray cleaning continues while the on-off valve 10 is open, but even if the hot water previously stored at an appropriate temperature in the heat transfer tubes 18-1 is used up, new While the supplied water flows through the heat conduction tubes 18-1..., it is efficiently heated by the heating section a-1 such as the planar heating element 17 to become hot water, and the temperature detection section d-1 is accurately detected. quickly electronically detects the temperature of the hot water, and the temperature detecting section d-1 and the temperature detecting section d-
1, the temperature of the hot water is always kept constant through the cooperation of the temperature control section e-1 which electronically controls the energization to the heating section a-1, even when used continuously for a long time. , the hot water does not get hot or cold.

In addition, heated toilet seat A-3 during use is toilet seat 4.
The toilet seat is heated by a heating part a-3 such as a tubing heater 30 mounted on the inner surface of the recess 4a on the back surface of the toilet seat 4, and is electronically heated by a temperature detecting part d-3 such as a thermistor 31 buried in the toilet seat 4. The toilet seat 4 is heated by the cooperative action of the temperature detection part e-3 which accurately and quickly detects the temperature of the toilet seat 4 and electronically controls the energization to the heating part a-3 based on this temperature detection part d-3. It is always kept at a constant temperature.

Next, when the private part has been washed, the opening/closing handle 10a is operated to close the opening/closing valve 10, and the injection of hot water is stopped. After washing the private parts, in order to dry the washing water adhering to the private parts with warm air, use the push button 39 provided on the operation part D to operate the changeover switch Sw-wA to switch to the hot air device A-2. Then, the power supply to the heating circuit of the feed water heating device A-1 is stopped, and at the same time, the heating circuit and motor M of the hot air device A-2 are stopped.
etc. are energized, and the transport section 3 composed of the electric motor 34a, the Sirotskov fan 34b, etc.
At the same time as 4 starts to operate, hot air heated by the heating part a-2 made of the Nikrok wire 36 and the like is blown out from the blowing part 33 towards the private parts, thereby drying the parts. The temperature of the hot air heated by the heating section a-2 is detected by the temperature detection section d-2 such as the thermistor 32, and the temperature detection section d-2 and the temperature control section e-2 work together to detect the temperature of the hot air heated by the heating section a-2. -2 control is performed, and the temperature of the hot air blown out from the blowing section 33 is always kept constant. In addition, after drying the local area, turn the changeover switch Sw- again.
Operate wA using push button 39 to return it to its original state. Of course, the temperature settings for hot water, toilet seat 4, and hot air are controlled by variable resistors, which are temperature setting sections f-1, f-2, and f-3, respectively, provided in control box E.
It can be set arbitrarily by changing the resistance values of Rh-w, Rc-S, and Rc-A. In addition, in this embodiment, in addition to the feed water heating device A-1, the hot air device A-1 is also used.
-2. Although the heated toilet seat A-3 is loaded, the warm air device A-2 may not be provided, and a normal toilet seat may be used instead of the heated toilet seat A-3. Furthermore, a deodorizing device may be added.

〔Effect of the invention〕

As explained above, the sanitary cleaning device of the present invention has the following effects depending on its configuration.

(1) Including the temperature of the washing water for private washing supplied from the water supply heating device, the temperature of the warm air for drying from the hot air device, and the temperature of the heated toilet seat, adjust these target temperatures to the appropriate temperature. Along with the settings, the temperature is also controlled. Therefore, the toilet can be used comfortably during the entire process from sitting on the toilet seat to the end of washing and drying.

(2) A comparator is activated by a signal from a thermistor, and a light emitting element is provided which emits light by the output of this comparator, and the heating element is energized by a light receiving signal from a light receiving element optically coupled to the light emitting element. Since the switching element that opens and closes is controlled, there is almost no time delay in the control system from the thermistor to the switching element, and high-speed response can be achieved. Therefore, the range of temperature fluctuations in the wash water, hot air temperature, and toilet seat temperature can be reduced, and discomfort caused by temperature changes during use will not occur. Furthermore, since the temperatures of flushing water, hot air, and the toilet seat can be controlled by a single temperature control unit, the capacity of the equipment can be reduced compared to when each target is controlled by separate control units, and failures are also reduced. It becomes less.

(3) The cleaning water, warm air and toilet seat detection circuit of the temperature control unit and the heating circuit are insulated by optical coupling between the light emitting element and the light receiving element, so the heating element on the heating circuit side will not get wet. Even if this happens, it will not have any effect on the temperature detection circuit. Therefore, reliable temperature detection and temperature control can be performed, making it ideal for use as water-related equipment.

(4) Since a switching element is used as a means for opening and closing the current supply to the heating element and is driven by the light receiving element, it can be driven with small control power. Furthermore, since the washing water, hot air, and toilet seat are controlled by a single control unit, the control power can be further reduced compared to the case where these are controlled separately, and a sufficient power saving effect can be expected.

(5) Since a temperature setting section is provided, the temperature of the wash water, hot air, and toilet seat can be easily set to the user's preferred temperature, making it even more comfortable to use.
