Further, the casing 16 is bent forward at the side of the toilet bowl 1, and operating knobs for local cleansing water, warm air, etc. are arranged on the upper surface of the casing 16 to facilitate operation. Although the heated toilet seat 3 and the toilet lid 4 are pivotally connected to the casing 16 of the hot water device 2, they may also be pivotally connected directly to the toilet bowl 1.

Next, the route of the local washing water in the device of the present invention will be schematically explained with reference to FIG. Figure A shows the case of this embodiment, in which the inlet 8 is provided upstream of the heating section a-1 of hot water for private washing installed in the water heating device 2, and a check valve is connected to the water supply source A. connected via d. The spout 9 is opened into a nozzle 10 for cleaning private parts. One path connects to the inlet 8, and the other path connects to the jet port 9 via the heating section a-1 and vacuum breaker b, forming a main flow path 11, which branches from the upstream side of the vacuum breaker b, and connects to the main flow path 11. A vacuum breaker c, which is different from the roadside vacuum breaker b, and a path that connects to the flush water path of the toilet bowl 1 via the discharge port 13 constitute a sub-flow path 12.

FIG. 3B shows a case where the branch point of the sub-flow path 12 is provided upstream of the check valve d. The branching point of the sub flow path 12 is not limited to these A and B, and may be any branch point upstream of the vacuum breaker b of the main flow path 11.
It may be provided between the heating part a-1 and the vacuum breaker valve b. These three examples differ only in the branching position of the sub-channel 12, and the configuration of each channel is the same, so the case shown in FIG. 3A will be described in more detail.

A branch tap C is provided in the water supply pipe B that communicates with the water supply source A (see FIGS. 23 and 24). Water supply pipe B
A part of the water flows into this branch tap C, flows as shown by the arrow, and is led to the water heater 2 through its outlet 14, but the rest is led to the toilet bowl cleaning tank 5 through the water supply pipe B. The branch tap C is composed of a water stop valve e, a strainer f, and a check valve d. When the water stop valve e is opened in the branch valve C, water passes through the strainer f and enters the check valve d. It is pushed open and flows to the outlet 14. The stop valve e is provided with a cone e' so that the flow rate can be finely adjusted. In addition, D is the main tightening handle of the water supply pipe B.

The water that has passed through the branch tap C passes through the conduit 15 and enters the inlet 8 in the hot water device 2 as shown in FIGS. 4 to 11.

Reference numeral 17 denotes a fixing member for the casing 16 that houses the toilet bowl 1, the water heater 2, etc. Further, the outlet 6 and the hot air outlet 7 of the nozzle 10 are provided adjacent to the front surface of the side portion 16a of the casing 16.

The water from the branch tap C passes through the conduit 15 and is led to the hot water device 2 in the casing 16 from the inlet 8, and passes through the on-off valve h, flow rate adjustment valve i, and distribution valve j in sequence through the conduit 15'. Here, it is divided into the main flow path 11 and the sub flow path 12, one of which flows into the heating section a-1 for private wash water, and the other reaches the discharge port 13 via the vacuum break valve C.

The heating section a-1 includes a heat transfer tube 18 formed by bending a steel pipe or the like with good thermal conductivity into a serpentine shape, and a planar heating element 19' which is a heater that heats the heat transfer tube 18 from the outside.

An example of the structure of this nozzle 10 will be described with reference to FIGS. 12 to 16. The nozzle 10 has a telescopic structure, and the fixed outer cylinder 20 is inserted into the casing 16 diagonally downward by a screw 30 (see FIG. 4). An inner cylinder 21 having a piston portion 21c is housed within the base plate 16c. The inner cylinder 21 is a fixed outer cylinder 20
Guide pipe 2 for local washing water provided concentrically inside

A small cylinder 25 that has a pressure receiving plate 21a and can be rotated by a knob 24 is installed inside the tip of the inner cylinder 21.
Alternatively, a small hole 9a and a group of small holes 9b having different diameters are bored at 180° different positions to form a spout 9, and the spout 9 is selected by a knob 24 that rotates a small cylinder 25. A relatively large hole 9c communicating with the small hole 9a or the small hole group 9b is bored in the peripheral wall of 21.
Therefore, if the small holes 9a and the holes 9c communicate with each other, local washing water will be ejected in a nozzle-like manner, and if the small hole group 9b and the holes 9c are in communication with each other, the water will be ejected in a shower-like manner. 26 is knob 2
4 is a positioning stopper, 27 is an inlet for local washing water, and 28 is an inlet for branched water. Main channel 1
The branched water that separates from the toilet bowl 1 and travels through the sub-channel 12 is used for the projecting action of the telescopic nozzle 10 before being drained into the flushing water path of the toilet bowl 1.

That is, the branched water enters around the guide tube 22 in the fixed outer cylinder 20 from the inlet 28, pushes the piston part 21c of the inner cylinder 21, causes the inner cylinder 21 to protrude against the elastic pressure of the spring 23, and the inner cylinder 21 piston part 21
The fixed outer cylinder 20
Water is drained into the toilet bowl 1 through a discharge port 13 provided at the tip of the toilet bowl 1. On the other hand, local washing water heated to an appropriate temperature is
From the inlet 27, the water passes through the guide tube 22 in the fixed outer cylinder 20 and enters the protruding inner cylinder 21, and the water pressure of the local washing water is applied to the pressure receiving plate 21a provided in the small cylinder 25, pushing the inner cylinder 21. , while holding the inner cylinder 21 in a stable protruding state, it flows into the small cylinder 25 through the small hole 21b, and is ejected toward the local area from the spout 9 consisting of the small hole 9a or group of holes 9b selected by the knob 24. It is. When the water flowing through the main flow path 11 and the sub flow path 12 is stopped by the on-off valve h, the piston portion 21
c. The water pressure on the pressure receiving plate 21a disappears, and the inner cylinder 21 is retracted by the spring 23.

Further, the water in the main flow path 11 in the nozzle 10 is discharged into the toilet bowl 1 through the small hole 21b, the spout 9, and the hole 9c, and the water in the sub flow path 12 is discharged into the toilet bowl 1 through the small hole 29 and the discharge port 13. is discharged.

Next, FIGS. 17 to 19 show another embodiment of the structure of the nozzle 10, in which local washing water is jetted out after the inner cylinder 21 is completely protruded. The inner cylinder 21 is fixed to the outer cylinder 2 by a spring 23.
It is contained within 0. The spring 23 is the fixed outer cylinder 20
The inner cylinder 21 is connected to the lid 3 by screws 31, 31' between the lid 31'a of the inner cylinder 21 and the piston part 21c of the inner cylinder 21.
It is fixed so as to be pulled in the direction of 1'a. The branched water enters the rear of the inner cylinder 21 from the inlet 28,
By pushing the piston portion 21c, the inner cylinder 21 is made to protrude against the pressure of the spring 23. Fixed outer cylinder 20
An annular groove 20 is provided on the inner periphery of the
a is provided, and a through hole 21d is provided in the peripheral wall of the inner cylinder 21 so as to communicate with the annular groove 20a when the inner cylinder 21 protrudes. Therefore, the inner cylinder 2
1 protrudes due to the pressure of the branch water, the annular groove 2
0a and the through hole 21d are in communication, and the local washing water enters the inner cylinder 21 from the inlet 27 through the annular groove 20a and the through hole 21d, and then enters the spout 9 at the tip.
More gushing. The branched water passes through the through hole 20b and flow path 20c provided in the peripheral wall of the fixed outer cylinder 20 to the discharge port 1.
Water is drained from 3. In this case, the pores 29 provided in the piston portion 21c of the inner cylinder 21 are mainly formed in the inner cylinder 21.
Acts as a water hole when returning to normal condition.

That is, the sub flow path 1 stored in the fixed outer cylinder 20
This is to drain water from step 2. Therefore, water is drained from the discharge port 13 into the toilet bowl 1 through the pores 29, the through holes 20b, and the channels 20c.

Next, FIGS. 20 to 22 show still another nozzle 1.
0, and contrary to the above two embodiments, the local washing water is pushed into the inner cylinder 21 by its water pressure.
After protruding, it passes through the inner cylinder 21 and is ejected from the spout 9 at the tip thereof, and the branched water flows around the annular groove 20a and is ejected from the outlet 13 to wash the inner cylinder 21. It is. For this purpose, a through hole 31a for private wash water is provided in the set screw 31 on the inner cylinder side of the tension spring 23. The annular groove 20a has a flow path 20c connected to the fixed outer cylinder 2 so as to communicate with the discharge port 13.
Set to 0. Note that the through hole 20b acts as a hole through which air enters and exits so that the inner cylinder 21 can easily slide.

Reference numeral 21e is a protrusion provided in front of the spout 9 of the inner cylinder 21 to prevent the water in the sub-flow path 12 discharged from the discharge port 13 from flowing into the spout 9, and to prevent the private water from flowing into the spout 9. This is to prevent further eruption. To explain the operation of this nozzle 10,
Local washing water flowing through the main channel 11 flows in from the inlet 27, causes the piston portion 21c to protrude the inner cylinder 21 against the elastic pressure of the spring 23, and enters the inner cylinder 21 through the through hole 31a, and the water enters the inner cylinder 21 through the through hole 31a. More gushing. On the other hand, the branched water flowing through the sub-flow path 12 flows into the annular groove 20a through the inlet 28, passes through the flow path 20c, flows out from the outlet 13, cleans the inner cylinder 21, and is discharged into the toilet bowl 1. When the water in the main channel 11 and the sub channel 12 flowing into the nozzle 10 stops, the water pressure applied to the piston part 21c disappears, and the spring 23 springs the inner cylinder 2.
1 retracts.

In this way, the local washing water flowing through the main flow path 11 is automatically adjusted to the appropriate temperature by the heating section a-1 and the temperature control section g-1, and reaches the nozzle 10 via the vacuum breaker b, where it protrudes. The liquid is ejected from the spout 9 at the tip of the inner cylinder 21 to cleanse the private parts. On the other hand, the branched water flowing through the sub-flow path 12 reaches the fixed outer cylinder 20 of the nozzle 10 through the vacuum break valve C, is used for the protruding action of the inner cylinder 21, the cleaning action, etc., and is discharged into the toilet bowl 1. , and then connects to the normal flush water drainage path of the toilet bowl 1. Of course, the nozzle 10 does not have to have an expandable structure as described above, and may be a fixed nozzle.

Further, the branch water outlet 13 does not need to be provided in the nozzle 10, and may be provided so that the water simply flows out into the toilet bowl cleaning tank 5, or may be directly discharged into the toilet bowl 1.

Furthermore, the fixed outer cylinder 2 constituting these nozzles 10
0, the inner tube 21, the small tube 25, etc. are made of synthetic resin such as ABS resin or polyacetal resin, and may be plated if necessary. Further, these may be made of metal or may be plated.

If it is made of synthetic resin, it has low thermal conductivity and corrosion resistance, so the local washing water heated to an appropriate temperature that is ejected from the spout 9 will not cool down, will not cause discomfort, and will not cause water scale etc. on the sliding part of the nozzle 10. nozzle 10 without sticking
This is particularly preferable because it does not cause sliding defects.

Furthermore, the configuration of each part of the hot water device 2 will be explained.

The on-off valve h shown in FIG. 25 is fixed to the substrate 16c and has a valve housing 32 connected to one end of the conduit 15'.
A valve body 3 is attached to the lower end of a spindle 34 that moves up and down with the rotation of the opening/closing handle 33 relative to the water inlet 32a.
5 is installed so that the valve body 35 can be moved in and out. A water outlet opened in the valve housing 32 communicates with a water inlet 38a provided in the valve housing 38 of the flow rate regulating valve 1 connected to the valve housing 32 (see FIG. 27). The opening/closing handle 33 is provided on the upper surface of the vertical portion 16b of the casing 16 of the hot water device 2 at a position where it can be easily operated while sitting on the heated toilet seat 3.

Note that the on-off valve h can also have a known electromagnetic valve structure as shown in FIG. In the same figure, 36 is an electromagnetic coil (SoL), 35 is a valve body, 3
7 is a core operated by an electromagnetic coil.

The flow rate regulating valve i shown in FIG. 27 sets the amount of water flowing into the hot water device 2 to a level higher than the insensitive amount of water of the water meter, and has a water inlet 38a formed by a partition wall 39 and a diaphragm 40 inside the valve casing 38. A chamber 41, a middle chamber 42 equipped with a water outlet 38b, and a lower chamber 43 communicating with the atmosphere are formed into sections. A through hole 44a is formed in the member 44 screwed to the partition wall 39, and a valve body 45 having a shaft portion 45a is attached to the diaphragm 40 so as to be inserted through the through hole 44a. shaped taper part 4
5b, and the valve body 45 is always pressed upward by a spring 46 disposed in the lower chamber 43. Also, the elastic force of this spring 46 is determined by the flow rate adjustment knob 4.
It can be adjusted by 7.

Therefore, when water is flowing, spring 4
6 and the water pressure applied to the diaphragm 40 are balanced, and the water flowing in from the water inlet 38a flows into the valve body 4.
The water flows out from the water outlet 38b through the gap between the taper portion 45b of No. 5 and the through hole 44a. If the flow rate adjustment knob 47 is rotated to press the spring 46 upward, the valve body 45 will rise and the gap between the tapered portion 45b and the through hole 44a will be widened, increasing the flow rate. Conversely, the flow rate can be reduced.

Further, when a change occurs in the water pressure of the water flowing in from the water inlet 38a, for example, when the water pressure increases, the diaphragm 40 moves downward due to the increase in water pressure, and with this movement, the valve body 45 moves downward. Then, the gap between the tapered portion 45b and the through hole 44a is narrowed, and the flow rate is kept constant. When the water pressure decreases, it operates in the opposite manner, and the flow rate is always maintained constant despite changes in water pressure, making it possible to make the amount of water flowing into the water heating device 2 greater than the insensitive water amount of the water meter.

Note that the flow rate regulating valve i may be divided into a valve exclusively for flow rate regulation, such as a needle valve, and a pressure regulating valve exclusively for pressure regulation.

In this case, a pressure regulating valve is not necessarily necessary, but
Preferably hot.

Next, the distribution valve j shown in FIG. 29 divides the water that has passed through the flow rate regulating valve i into two parts, and uses one of them as private parts washing water in the heating part a- of the main passage 11. 1, and the other water is distributed to the sub-channels 12 as branch water,
The inside of the valve housing 48 has a first chamber 49 and a second chamber 50 in the axial direction.
and a third chamber 51, these three chambers are in communication with each other through tapered valve seat holes 52, 53, and a valve seat is connected to and separated from the valve seat holes 52, 53. Tapered valve bodies 54 and 55 that relatively adjust the amount of water passing through the holes 52 and 53 are installed movably in the axial direction. The valve body 54 has a valve stem 56 on one side.
is formed and protrudes from the casing 16, and the other passes through the valve seat hole 52, reaches the valve seat hole 53, and comes into contact with the valve body 55. The valve body 55 is always pressed toward the valve seat hole 53 by a spring 55a.

An adjustment knob 57 is provided on the shaft end of the valve shaft 56, and the water inlet 48a is connected to the second chamber 50 and the main channel 11 is connected to the first chamber 49.
The side water outlet 48b and the third chamber 51 are connected to the sub flow path 1.
The configuration is such that two water outlets 48c are provided on each side.

Therefore, by rotating the adjustment knob 57 in either the left or right direction and moving the valve shaft 56 in the axial direction, the valve bodies 54 and 55 are moved, so that the valve seat hole 52
The amount of water passing through the second chamber 50 and the amount of water passing through the through hole 53 can be selected in relative proportions, so that the amount of water passing through the second chamber 50
According to these ratios, the amount of water flowing into the chamber is distributed to the first chamber 49 and the third chamber 51, respectively, and an appropriate amount of water is distributed from the respective water outlets 48b and 48c to the main flow path 11 and the sub flow path, respectively. It leaks out to 12. The adjustment knob 57 is provided so as to protrude from the side surface of the casing 16 of the hot water device 2, so that the above-mentioned distribution action can be performed appropriately.

In this embodiment, the flow rate adjustment valve i is used to connect the hot water device a-
The flow rate of hot water spouted from the spout 9 is adjusted by setting the flow rate flowing into the water outlet 1 and adjusting the distribution valve j to change the ratio of local wash water and branch water. Keeping the ratio of valve j constant,
The flow rate of hot water can also be changed using a flow rate adjustment valve i.

Next, vacuum breaker valves b and c shown in FIG. 28 will be explained.

A valve housing 59 is provided in the middle of the flow path between the water inlet 58a and the water outlet 58b of the valve housing 58, and a water valve seat 60 is provided at the lower part of the valve chamber 59.

3a and a guide portion 63b.

The valve housing 58 and the lid 63 may be made of metal or may be formed of a material with low thermal conductivity, such as synthetic resin such as ABS resin or polyacetal resin. In case,
It is preferable to use synthetic resin because it allows the passage of private wash water heated to an appropriate temperature.

The valve body 62 is made of a material lighter than water, such as polypropylene, and a water valve seat 60 is provided at the bottom.
A water valve 62a that comes into contact with and separates from the air valve seat 61, a valve shaft 62c having a guide hole 62g that slides on the guide portion 63b at the upper part, and an air intake valve 62b that comes into contact with and separates from the air valve seat 61 in the middle part. It is integrally provided with an annular groove 62f to be fitted.

Further, the lower peripheral edge of the water valve 62a protrudes to form a pressure reservoir 62e on the lower surface. 62b is a ventilation hole for facilitating sliding between the guide portion 63b and the guide hole 62g. When water flows through the main flow path 11 or the sub flow path 12 and enters from the water inlet 58a, the water pressure pushes up the valve body 62, opens the water valve 62a from the water valve seat 60, and opens the air intake valve 62b.
Since the valve chamber 59 is brought into close contact with the air valve seat 61,
The air side is closed to keep the water flow path open, and water flowing in from the water inlet 58a passes through the valve chamber 59, flows out from the water outlet 58b, and flows toward the nozzle 10. However, if negative pressure is generated on the upstream side of the vacuum breaker valves b and c for some reason during use and backflow pressure is generated, the valve body 62 falls down in cooperation with atmospheric pressure, and the air suction valve 62b is closed to the air valve seat 61. The valve chamber 59 is further opened and the water valve 62a is brought closer to the water valve seat 60.
is opened to the atmosphere, the backflow of water is prevented in the valve chamber 59, and impure sewage, etc., does not flow into the heating section a-1 located upstream of the vacuum breaker valves b and c, or into the water supply source. It is hygienic and can be used with confidence.

In addition, after using this hot water device 2, the local washing water or branch water stored in the nozzle 10 that has been heated to an appropriate temperature can be discharged, so the next time it is used, it can be immediately flushed from the spout 9 of the nozzle 10. It is comfortable to use because it squirts out water for washing your private parts at an appropriate temperature, and you won't feel cold.

The temperature control of the heated toilet seat 3 is also based on the detection of the temperature detection section l-2 by the casing 1 of the water heating device 2.
This is automatically performed by the temperature control section g-3 installed in the temperature controller g-3.

Figure 33 shows an example in which a solenoid valve SoL is used as an on-off valve for a hot water device, and a rotary switch, for example, is used for the changeover switch Sw-WA of hot water device a and hot air device k to integrate the operating section. .

Therefore, when this sanitary cleaning device is not in use,
That is, in the state shown in the figure, only the heating circuit of the hot water device 2 is energized, the hot water is automatically heated and kept warm, and the temperature is automatically adjusted to an appropriate temperature. When the changeover switch Sw-WA is rotated to the left, the heating circuit of the water heating device 2 and the solenoid valve SoL are energized, the solenoid valve SoL is opened, and hot water is spouted from the spout 9 and inside the heat transfer tube 18. The flowing water is heated in the heating section a-1 and its temperature is automatically adjusted.

This control action will be explained according to Fig. 34.
It is as follows.

In the energized state, when the temperature of hot water, hot air, or the heated toilet seat 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 IC (I) is activated to increase the voltage at point C. voltage is high (H
state) become. When IC (I) is in the H state, the transistor Tr becomes conductive, the light emitting element L emits light, and the light receiving element C receives the light beam, which reduces the resistance of the light receiving element C, triggering the triac T, and making it conductive. state, current flows through the heating element Rh, and it heats up. When the temperature of hot water, hot air, or heated toilet seat increases, the resistance Rth of the thermistor decreases, and the voltage at point A becomes higher than the voltage at point B.
IC (I) operates and the voltage at point C becomes low (L state). When IC (I) goes into the L state, the transistor Tr is selected, the light emitting element L stops emitting light, and the resistance of the light receiving element C increases, the trigger T loses its trigger and becomes the selected state, and the heating element Rh The power supply is stopped and heating is stopped.
Variable resistance for temperature adjustment when adjusting the temperature
Adjust Rc. That is, if the resistance of the variable resistor Rc is increased by operating the temperature adjustment knob, 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
As the temperature rises, the resistance Rth of the thermistor decreases, and current is applied to Rh until the voltage at point A becomes higher than the voltage at point B. That is, in contrast to the high temperature setting, if the resistance of the variable resistor Rc is made small, the low temperature is set. Note that the electric circuit is not limited to this embodiment and can be freely modified. As in this embodiment, if the temperature is detected by a thermistor and the energization to the heating part a of the heating element Rh is electronically controlled by a thyristor such as a triac T, the response speed to temperature can be increased.
Temperature control can be performed accurately and failures are rare.

Of course, the energization to the heating section may be controlled by phase control or time proportional control of the thyristor.

In addition, in this sanitary cleaning device, the heating part a-1
The system may be of a hot water storage type, an instantaneous type, or a combination thereof, and as in this embodiment, additional functions such as a hot air device, a heated toilet seat, and a deodorizing device may also be added in an appropriate combination.

As described above, the present invention provides the following effects.

(1) Since the private parts are washed with hot water, the product does not feel cold during washing, making it comfortable to use and hygienic.

(2) Even if the amount of washing water spouted from the spout is small, water can be discharged from the outlet, and the amount of water flowing into the inlet can be greater than the insensitive water amount of the water meter, so it can be used in any location. .

(3) Vacuum breaker valves are installed in the main flow path and the sub flow path, so even if negative pressure occurs in the water supply source or heating section, sewage will not flow back into the water supply source or heating section and cause contamination, making it sanitary. Yes, you can use it with confidence.
Furthermore, the outlet can be provided at any location in the path of flushing water of the toilet bowl, and can be used for flushing the toilet bowl, etc., and water can be used effectively.
