Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sanitary cleaning device having a function of drying a private part by blowing warm air after cleaning with cleaning water.

[Conventional technology and problems]

Recently, sanitary cleaning devices have been provided that jet hot water to the private parts of the body after using the toilet to cleanse the private parts, and then dry the private parts with warm air.

When installing electrical equipment such as an electric heating device and its control device to generate warm air to such sanitary cleaning equipment, it is necessary to install the electric heating device because the surrounding area is wet with water or has a humid atmosphere. Even if it gets wet, it is necessary to avoid electric shock accidents and malfunction of the control device due to electrical leakage.

By the way, in an electric heating device for generating hot air, both the heating element that heats the air and the switching element such as a thyristor that turns it on and off are used.
Connecting directly to a 100V power supply is advantageous in that it does not require a large capacity transformer. Further, in this case, in a typical circuit configuration, a control signal from the control circuit is directly connected to a control terminal of a thyristor that turns on and off the heating element. This means that because a 100V power supply voltage is applied close to the hot air temperature adjustment knob that people touch, there is a risk of electric shock due to electrical leakage if the knob is touched with wet hands. do. Furthermore, since the sanitary cleaning device is installed in a humid atmosphere, there is a problem in that the thyristor is erroneously turned on due to electrical leakage, causing the circuit to malfunction.

Sanitary cleaning equipment is used by everyone from children to the elderly without electrical knowledge, so it is necessary to ensure safe and reliable operation. In the unlikely event that an electric shock occurs, even if it does not result in an accident, it is expected that the shock will cause distrust of sanitary cleaning equipment, so it must be avoided at all costs.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sanitary cleaning device that can ensure safety as a water-related device and stable operation, especially regarding hot air devices. shall be.

Figure 1 is a perspective view of the sanitary cleaning device with the lid closed;
The figure is a perspective view with the lid open. In Figures 1 and 2, 1 is a toilet bowl, 2 is a toilet cleaning tank installed behind it, and A is a mounting bracket 1a (see Figure 4) that straddles the toilet bowl 1 behind it. The main body of the sanitary washing device is attached, 3 is a toilet seat controlled by a toilet seat heating device, and 4 is a toilet lid. The sanitary washing device main body A includes a hot water washing device A- which will be described later.
1. A toilet seat heating device A-2 and a hot air device A-3 are built-in.

Figures 3 and 4 are a partially cutaway plan view and a partially cutaway front view of the sanitary cleaning device main body A, respectively.
The figure and FIG. 6 are a vertical side view and a bottom view. 7, FIG. 8, FIG. 9, and FIG. 10 are sectional views taken along lines -, -, -, and - in FIG. 3, respectively.

The case 5 of this sanitary cleaning device main body A is formed into a substantially L-shape in plan, and is composed of a casing 5a made of synthetic resin such as ABS resin, and a substrate 5b such as a pressed stainless steel plate (see Fig. 5). ),
Inside it is a hot water cleaning device A-1 and a hot air device A.

As clearly shown in FIG. 4, the hot water cleaning device A-1 in this embodiment includes an on-off valve 9, a flow rate adjustment valve 10, a distribution valve 11, a hot water section 12, and a vacuum breaker valve 2.
5, 25', an ejection part b, an electric control part c-1, a temperature detection part d-1, etc.

As shown in FIG. 5, the casing 5a
One end of the connecting fitting 6 attached to the lower back side of the case is connected to a water supply source X via a branching fitting 7 to be described later, and the other end is connected to one end of a water conduit 8 made of, for example, a copper pipe within the case 5. The other end of this water pipe 8 is connected to the water supply to the heat transfer pipe 13 that constitutes the hot water section 12 via an on-off valve 9 that is manually opened and closed midway, a flow rate adjustment valve 10 that serves both flow rate adjustment and pressure adjustment, and a distribution valve 11. It is in contact with port 13a.

In addition, as shown in FIGS. 16 and 17, the branch fitting 7 is connected to, for example, a water supply pipe that supplies water to a ball tap (not shown) of the toilet bowl cleaning tank 2.
It is composed of a water stop valve 15, a strainer 16, and a check valve 17. The stop valve 15 is provided with a cone 15a to facilitate fine adjustment of the flow rate.

The on-off valve 9 is configured to be opened and closed by manual operation, and its on-off handle 9a is provided so as to protrude forward from the upper surface of the side of the case 5 so that it can be easily operated while sitting on the toilet seat 3. (See Figures 1 and 2).

That is, as shown in FIG. 11, the valve housing 9b of the on-off valve 9 is attached and fixed to the base plate 5b, and the on-off handle 9a protrudes from the casing 5a. In addition,
Instead of this on-off valve 9, other means such as a solenoid valve may be used.

In addition, as shown in FIG. 12, the flow rate adjustment valve 10 includes a flow rate adjustment valve section 19 that adjusts the amount of flowing water in a valve housing 18 connected to the on-off valve 9, and a flow rate adjustment valve part 19 that adjusts the flow rate by sensing water pressure fluctuations. A diaphragm 20 that automatically adjusts the opening degree of the valve portion 19, a coil spring 21 that always biases the flow rate adjustment valve portion 19 in a direction to increase the opening degree, and a flow rate adjustment knob 22 that manually adjusts the elastic force of the coil spring 21. It is equipped with

Therefore, when water is flowing, the elastic force of the coil spring 21 and the water pressure applied to the diaphragm 20 are balanced, and the water flows through the outlet of the on-off valve 9 (not shown) and the inlet of the flow rate adjustment valve 10. 18
a. It flows out from the outlet 18b via the flow rate adjustment valve section 19 and reaches the distribution valve 11.

In this state, if the flow rate adjustment knob 22 is rotated to press the coil spring 21 upward, the opening degree of the flow rate adjustment valve section 19 will be increased and the flow rate can be increased. can be reduced.

In addition, if a change occurs in the water pressure, for example, when the water pressure increases, the increase in water pressure causes the diaphragm 2 to
0 moves downward against the elastic force of the coil spring 21 to reduce the opening degree of the flow rate regulating valve section 19 and keep the flow rate constant.

When the water pressure decreases, the opening of the flow rate regulating valve section 19 increases in the opposite manner, and the flow rate is always maintained constant regardless of changes in water pressure.

The distribution valve 11 is connected to the substrate 5 as shown in FIG.
An inlet 11a that is attached and fixed to b and communicates with the flow rate adjustment valve 10, a first outlet 11b that communicates with an ejection hole 27f of the ejection part b, and a discharge hole 26f of the ejection part b through the hot water section 12, which will be described later. 2nd outlet 1
1c, and a distribution valve that approaches and separates from tapered valve seat holes 11d and 11e provided oppositely so as to distribute water flowing in from the inlet 11a to the first outlet 11b and the second outlet 11c, respectively. body 11f,1
1g and the same valve body 11f, 11g's valve seat hole 11d, 1
It has a configuration including an adjustment knob 11h that adjusts the contact and separation with respect to 1e.

The adjustment knob 11h protrudes from the casing 5a and is provided at the upper rear of the side surface of the case 5. If the adjustment knob 11h is rotated to move the distribution valve bodies 11f and 11g to the right, the valve body 11f approaches the valve seat hole 11d, and the first outlet 11
As the flow rate flowing out from b decreases, the valve body 11
g is separated from the valve seat hole 11e, and the flow rate flowing out from the second outlet 11c increases. When the rotating operation is performed in the opposite direction, the flow rate flowing out from the first outlet 11b increases and the flow rate flowing out from the second outlet 11c decreases. That is, by operating the adjustment knob 11h, the ratio of the flow rates flowing out from the first outlet port 11b and the second outlet port 11c can be changed without changing the flow rate flowing into the inlet port 11a.

Note that this distribution valve 11 is used together with the flow rate adjustment valve 10 as a countermeasure for the insensitive amount of water in a water meter. Thereafter, the distribution valve 11 connects the hot water path which will be described later to the hot water section 12, the vacuum breaker valve 25, the spout 27f for private cleaning of the spout section b, and the vacuum breaker valve 25 to the discharge port 26f of the spout section b. The surplus water is distributed to the

That is, the water flowing out from the first outlet 11b of the distribution valve 11 is heated by the hot water section 12 and reaches the spouting section b as hot water for private washing, and then flows through the second outlet 11c.
The excess water flowing out directly reaches the spouting part b without passing through the hot water part 12.

In this embodiment, the flow rate of water flowing into the hot water cleaning device A-1 is set by the flow rate adjustment valve 10, and the distribution valve 11 is adjusted to change the ratio of cleaning water to surplus water. Although the flow rate of hot water spouted from b is adjusted, on the contrary, the ratio of the distribution valve 11 can be kept constant and the flow rate of hot water can be changed using the flow rate regulating valve 10. In addition, if measures against the insensitive water amount are not required, the flow rate adjustment valve 10 and the distribution valve 11 are not necessarily necessary, and the flow rate of hot water may be adjusted by changing the opening degree of the on-off valve 9.

Next, the heat exchanger tube 13 constitutes the hot water section 12 together with the planar heating elements 23 attached to the left and right outer sides thereof, and is made of a metal tube such as a copper tube with good thermal conductivity, and includes a bent tube 13b and a straight tube 13c. These are combined by brazing, etc. In this embodiment, the straight pipes 13c are arranged side by side in the horizontal direction, and the straight pipes 13c are connected by a vent pipe 13b. As shown in FIG. 14, the planar heating element 23 constituting the heating part a-1 that heats the heat exchanger tube 13 from the outside has a skin resin layer 23a made of polyester or the like, an aluminum foil circuit, and an aluminum foil circuit. A heating conductor 23b such as, an intermediate resin layer 23c made of polyester or the like, a lower resin layer 23d, and an adhesive layer 23e to which a release paper 23f is attached are sequentially layered into a flat plate and integrally formed. Then, the release paper 23f of the planar heating element 23 is peeled off, and a heat transfer plate 24 such as a copper plate fixed by brazing or the like is attached to the outside of the heat transfer tube 13 using an adhesive layer 23e. The water supply port 13a of the heat transfer tube 13 is connected to the distribution valve 1.
1, and the outlet 13d connects to the ejection hole 27f of the ejection part b via the vacuum breaker valve 25.
contact. In addition, a thermistor 31 with a negative characteristic constituting the temperature detection part d-1 is placed near the outlet 13d of the heat exchanger tube 13, apart from the planar heating element 23.
The device is installed on the pipe wall. FW is a temperature fuse attached to the hot water section 12. Note that the hot water section 12 may be of a tank type, and the heating section a-1 may be a sheathed heater or the like. Furthermore, a positive temperature platinum thermistor, a thermocouple, or the like may be used as the temperature detection section d-1. Further, a bimetal switch or the like may be used instead of the temperature fuse F-W.

As shown in FIG. 15, the vacuum break valves 25 and 25' include an air valve 25d that opens and closes between the outlet 25b and the air hole 25c, and a water valve 25e that opens and closes between the inlet 25a and the outlet 25b. are respectively provided on the upper and lower surfaces of the same valve body 25f, and when water flows, the water pressure of the inlet 25a pushes up the valve body 25f and opens the water valve 25e, and the inlet 25a and the outlet 25b are opened.
At the same time, the air valve 25d closes, and when the flow of water stops, the valve body 25f descends due to its own weight, and the water valve 25e is closed, and at the same time, the air valve 25d
is opened, the outlet 25b communicates with the air hole 25c, the vacuum state on the downstream side is destroyed, and backflow of water to the upstream side is prevented. In this embodiment, the main body of the vacuum breaker valve 25 is made of ABS resin, and the valve body 25f
is made of a synthetic resin with low heat capacity and low thermal conductivity, such as polypropylene resin. Vacuum breaker valve 2
5 and 25' are not necessarily required and may be omitted.

As shown in FIG. 9, the spout part b is installed in a substantially central portion of the case 5 in an oblique manner toward the inside of the toilet bowl 1. The details are shown in FIGS. 18 to 22. In this embodiment, the ejection part b is the ejection part main body 26.
It is composed of a nozzle 27 that is extendable and retractable with respect to the ejection part main body 26. Main body 26 and nozzle 27
is made of synthetic resin such as ABS resin or polyacetal resin, and is plated if necessary.
Alternatively, they may be formed of metal. The spout main body 26 is provided with a hot water supply port 26a and a surplus water supply port 26b, and the hot water supply port 26a is connected to the inner cylinder 2.
6c, the surplus water supply port 26b communicates with an opening 27c provided on the upper surface of the tip of the nozzle 27, and a cylindrical chamber 26d formed between the spout main body 26 and the inner cylinder 26c, and a cylindrical chamber 26d. Nozzle 2 sliding inside
A small hole 27b opened in the piston part 27a of 7,
The annular chamber 26e formed by the small diameter portion of the main body 26 and the nozzle 27 communicates with a discharge hole 26f opened in the distal end surface of the ejection part main body 26. Nozzle 27
is guided by the cylindrical chamber 26d and the inner cylinder 26c and slides inside the jetting part main body 26, and is provided with a pressure receiving plate 27j having a small hole 27i. Also nozzle 27
A nozzle switching tube 27e that can be rotated 180 degrees by operating a knob 27d is fitted onto the outer periphery of the tip and is prevented from coming off by a retaining ring 27k. The above-mentioned openings 2 are provided on both upper and lower walls of the nozzle switching cylinder 27e.
Ejection holes 27f are drilled to correspond to 7c. One of the ejection holes 27f 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 27f can be selectively opened by switching the knob 27d. 27
It is arranged so that it is possible to obtain a desired ejection form such as a nozzle shape or a shower shape. Note that 26g is a positioning stopper for the knob 27d, which protrudes from the case 5. This positioning stopper 26g also serves to prevent dirty water from splashing onto the nozzle switching cylinder 27e when the spouting part b is not in use. Furthermore, 26h is attached to the tip of the main body 26 and serves to prevent the nozzle 27 from rotating.
This is a positioning ring with a shaped hole, and the small diameter portion of the nozzle 27 that slides on this positioning ring 26h is cut out in a D shape. Further, the nozzle 27 is always biased by a coil spring 27g in the direction of being housed inside the ejection part main body 26, so that the nozzle 27 is housed in the case 5 in a normal state.

Therefore, the hot water supply port 26a and the surplus water supply port 26
When hot water and surplus water are supplied to b, the pressure of the surplus water acts on the nozzle 27, respectively, and causes the nozzle 27 to protrude inward of the toilet bowl 1 against the elastic force of the coil spring 27g. The hot water is supplied to the inner cylinder 26a, the hollow chamber 27h of the nozzle 27, the pressure receiving plate 27j, and the desired spout hole 2 of the nozzle switching cylinder 27e.
Excess water is jetted toward the private parts from 7f to clean the private parts, and excess water passes through the cylindrical chamber 26d, the small hole 27b, and the annular chamber 26e, and is discharged into the toilet bowl 1 through the discharge hole 26f. Next, when the supply of hot water and surplus water is stopped, the surplus water in the cylindrical chamber 26d passes through the small hole 27b and the annular chamber 26e, and is gradually discharged into the toilet bowl 1 from the discharge hole 26f, and also in the hollow chamber 27h. The hot water inside is gradually discharged into the toilet bowl 1 through the small hole 27i of the pressure receiving plate 27j, the opening 27c, and the spouting hole 27f, and the nozzle 27 is contracted again by the elastic force of the coil spring 27g and stored in the spouting part main body 26. It is something that will be done. Note that the spouting part b does not have to be telescopic as in this embodiment. Similarly, the ejection hole 27f does not have to be switchable. In addition, surplus water is used to expand and contract the nozzle 27 and is discharged from the discharge hole 26f of the spout main body 26 to the toilet bowl 1.
It may also be used for cleaning Nozzle 7, and excess water can be used to clean Nozzle 2.
The water may be discharged directly into the toilet bowl 1 or the toilet bowl cleaning tank 2 without being used for expansion/contraction or cleaning of the toilet bowl 7.

Next, the temperature control function is as shown in Figure 28, hot water cleaning device A.
The explanation is as follows according to the electric circuit diagram of the -1 part.

In the energized state, when the temperature of hot water becomes low, the resistance Rth of the thermistor 31 which is the temperature detection part d-1 increases.
-W increases, and the voltage at point (a) of electric control section C-1 becomes lower than the voltage at point (b), forming a comparator.
ICI-W operates and the voltage at point (C) becomes high (H state). When ICI-W goes to H state, the transistor
Tr-W becomes conductive, and the light projecting element L-W emits light. When the light-receiving element Cd-W receives the light beam, the resistance of the light-receiving element Cd-W decreases, and the triac T-W is triggered to become conductive. The electric control section C-1 causes a current to flow through the heating element Rh-W of the heating section a-1, which includes the planar heating element 23 and the like.
As a result, the heat exchanger tube 13 is heated, and the heat exchanger tube 13
The temperature of the hot water inside will rise.

When the temperature of the hot water rises, the resistance Rth-W of the thermistor 31 becomes smaller, the voltage at point (A) becomes higher than the voltage at point (B), ICI-W is activated, and the potential at point (C) becomes lower. (L state). When ICI-W goes to L state,
Transistor Tr-W is cut off, and light emitter L-
W stops emitting light. Therefore, the light receiving element Cd
The resistance of -W increases, and the trigger T-W goes into a cutoff state because its trigger disappears, and the electric control section C-1 stops energizing the heating element Rh-W.
Heating to the heat exchanger tube 13 is stopped. When setting the temperature of the hot water, the variable resistor Rc-W, which is the temperature setting section C ₂ -1 of the electric control section C-1, is adjusted.
That is, if the resistance of the variable resistor Rc-W is increased, the voltage at point (a) will not become higher than at point (b) unless the resistance Rth-W of the thermistor 31, which is the temperature detection section d-1, becomes smaller. In other words, the electric control section C-1 controls the heating element Rh- which is the heating section a-1.
When the temperature of hot water becomes higher, thermistor 31 goes to W.
The current is applied until the resistance Rh-W becomes small and the voltage at point (a) becomes higher than the voltage at point (b). That is, the temperature is set to high temperature. On the contrary, if the resistance of the variable resistor Re-W is made small, the temperature can be set to a low temperature. The toilet seat heating device A-2 and the hot air device A-3 are controlled in the same way as the hot water washing device A-1. A block diagram of the electrical circuit diagram is shown in FIG. In addition, each electric control section C-
1, c-2, and C-3 are not limited to this embodiment, and can be constructed of any electrical circuit.
Of course, each heating section a can be
-1, a-2, and a-3 may be controlled.

The temperature setting sections C ₂ -1, C ₂ -2, and C ₂ -3 are not necessarily required.

A certain amount of water is supplied through the stop valve 15, strainer 16, and check valve 17 that constitute the heat transfer tube 1, and passes through the on-off valve 9, flow rate adjustment valve 10, and distribution valve 11.
3, the water is sufficiently heated to an appropriate temperature, and as the water is supplied, the upper outlet 13
Hot water previously stored at an appropriate temperature in the heat transfer tube 13 is pushed out from d, supplied to the spouting part b via the vacuum breaker valve 25, and sprayed toward the private part from the spouting hole 27f, thereby cleaning the outside. Therefore, the private parts can be washed with warm water at an appropriate temperature immediately after the start of use. Note that while the on-off valve 9 is open, even if the hot water stored in the jet cleaning is used up, newly supplied water will be used to flush the heat exchanger tubes 13.
While flowing inside, the heating part a of the planar heating element 23 etc.
-1 is efficiently heated to become hot water, and the temperature detection part d-1 accurately and quickly detects the temperature of the hot water, and based on the temperature detection part d-1 and the temperature detection part d-1, the heating part a The temperature of the hot water is always kept constant by the cooperation of the electric control unit c-1 that controls the power supply to the c-1, so even if it is used continuously for a long time, the hot water will not get hot or cold. do not.

In addition, the toilet seat heating device A-2 during use is heated by a heating part a-2 such as a tubing heater 29 installed inside the recess 3a on the back surface of the toilet seat 3, and a thermistor buried inside the toilet seat 3. 3
An electric control unit c-2 that accurately and quickly detects the temperature of the toilet seat 3 by a temperature detection unit d-2 such as 0, and controls the energization to the heating unit a-2 based on this temperature detection unit d-2. This action keeps the toilet seat 3 at a constant temperature.

Next, when the private part has been washed, the opening/closing handle 9a is operated to close the opening/closing valve 9, 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, operate the changeover switch SW-WA to switch to the hot air device A-3. Then, the heating circuit of the hot water cleaning device A-1 is de-energized, and at the same time the heating circuit of the hot air device A-3, the motor M, etc. are energized, and the conveying section constituted by the electric motor 34a, the sirotsukofan 34b, etc. 34 starts to operate, and heating section a made of nichrome wire 36 etc.
The warm air heated by the heating part a-3 is blown out from the outlet 33 toward the local area to dry the area. The temperature is detected by the temperature detection part d-3, and the heating part a-3 is controlled by the cooperative action of the temperature detection part d-3 and the electric control part C-3. The temperature is always kept constant. In addition, after drying the local area, operate the changeover switch SW-WA again.
Return it to its original state.

[Effects of the Invention] As explained above, in the present invention, the hot air temperature detection section, the hot air temperature setting section, and the hot air temperature control section are connected to a power source that is DC-insulated from the power source of the heating section. In addition, a relay section for transmitting an on/off control signal from the hot air temperature control section to the switching element of the heating section is constituted by a light emitting element and a light receiving element. In this way, the power supply for the heating section and the power supply for the hot air temperature control section are DC-insulated, so
Even if you touch the power supply unit by touching the adjustment knob etc. provided on the hot air temperature control unit with wet hands, the voltage of the power supply for the hot air temperature control unit is normally low enough to avoid the risk of electric shock. , there are no problems with any shots or accidents. In addition, the output signal of the warm air temperature control section is transmitted to the heating section by a relay section using a light emitting element and a light receiving element, and not only the power supply but also the signal transmission is performed in an electrically insulated state. Even if the heating element that makes up the part gets wet with water, the circuit of the heating part will not malfunction due to electrical leakage, etc., and reliable hot air temperature detection and hot air temperature control can be realized. It can be optimally used as a device. Furthermore, since a switching element and a light receiving element for driving the switching element are used as a means for controlling energization to the heating section, it has become possible to control a large amount of power with a small amount of control power.
