Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bidet for women or a sanitary cleaning device that sprays cleansing water to private parts such as the anus to clean the private parts, and in particular, the present invention relates to a sanitary cleaning device that sprays cleansing water to private parts such as the anus and the like. This invention relates to sanitary cleaning equipment.

[Conventional technology]

In conventional sanitary cleaning devices of this kind, a non-retractable nozzle is generally used as a private part cleaning nozzle for cleaning private parts after using the toilet. However, since the nozzle is located below the buttocks during use, it is unhygienic as dirt and sewage may splash onto the nozzle. Therefore, if the nozzle is placed in a retracted position, it becomes difficult to eject cleansing water accurately toward private parts.

As a countermeasure to this problem, a telescopic nozzle has been proposed that moves forward to point at the private parts only when cleaning and retreats during normal times.

For example, in Utility Model Application Publication No. 52-25459,
A nozzle is installed inside the cylinder so that it can freely move back and forth.
A cleaning device has been proposed in which a nozzle is advanced by the water pressure of cleaning water, and after cleaning, the nozzle is retreated using the restoring force of a spring.

A problem with such telescoping nozzles is that when the nozzle is retracted, the water that has accumulated in the cylinder is ejected from the nozzle tip and wets parts other than the private parts and clothing. The above-mentioned Utility Model Application Publication No. 52-25459 has the following countermeasures:
It is described that a water drain hole that communicates with the outside of the cylinder is provided in the piston portion at the base end of the nozzle.

[Problem that the invention seeks to solve]

However, in such conventional devices, the water discharged from the drain hole is simply flushed into the toilet bowl as unnecessary water, which goes against the trend of water conservation.

Based on these circumstances, the present invention aims to use water discharged when the nozzle is retracted for cleaning the nozzle.

[Means for solving problems]

In order to achieve this object, the sanitary cleaning device of the present invention includes an inner cylinder whose base end communicates with the hot water supply port and whose tip end is open, inside the tubular spout main body. A nozzle having a hot water spouting hole at its tip is disposed on the outer periphery so as to be movable back and forth along its longitudinal direction, and an annular chamber is formed between the outer circumferential wall of the nozzle and the inner wall of the spout main body, A spring is disposed between the nozzle and the nozzle and has a biasing force that normally causes the nozzle to retreat into the jetting part main body, and a spring is disposed between the nozzle and the jetting part main body, A surplus water supply port is provided in the part, and a piston part is provided at the base end of the nozzle for moving the nozzle forward by receiving water pressure of the surplus water supplied from the surplus water supply port, the piston part A small hole is formed to communicate between the surplus water supply port and the annular chamber, and a discharge hole is provided at the tip of the spout body to discharge water in the annular chamber around the nozzle. It is characterized by

〔Example〕

Hereinafter, features of the present invention will be specifically explained based on embodiments shown in the drawings.

1 to 24 show one embodiment of the present invention.
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-1, a toilet seat heating device, and a hot air device A-2, which will be described later.

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 longitudinal sectional side view and a bottom view. In addition, FIGS. 7, 8, 9, and 10 are the - lines, - lines, and - lines of FIG. 3, respectively.
It is a sectional view taken along the line and the - line.

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.
-2 is stored.

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 back side of the lower part of the is connected to the water supply source The other end of the water pipe 8 is connected to the water supply port 13a of 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. I'm in touch.

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.

Further, as shown in FIG. 12, the flow rate adjustment valve 10 is connected to the on-off valve 9, and has a flow rate adjustment valve part 19 in the valve housing 18 that adjusts the amount of flowing water, and a flow rate adjustment valve that senses water pressure fluctuations. A diaphragm 20 that automatically adjusts the opening degree of the valve part 19, a coil spring 21 that always biases the flow rate adjustment valve part 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 flow rate adjustment valve 10. Entrance 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; if the flow rate adjustment knob 22 is rotated in the opposite direction, the flow rate can be increased. The flow rate 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, and a first outlet 11 that communicates with the spout hole 27f of the spout part b via the hot water part 12, which will be described later.
b and a second outflow port 11c that communicates with the discharge hole 26f of the spouting part b, and a second outflow port 11c that faces each other so as to distribute water flowing in from the inflow port 11a to the first outflow port 11b and the second outflow port 11c, respectively. Distribution valve body 11 that approaches and separates from tapered valve seat holes 11d and 11e
f, 11g and the valve seat hole 11 of the same valve body 11f, 11g
d, 11e, and an adjustment knob 11h for adjusting the contact and separation.

The adjustment knob 11h protrudes from the casing 5a and is provided at the upper rear of the side surface of the case 5. Rotate this adjustment knob 11h to adjust the valve body 11.
If f and 11g are moved to the right, the valve body 11f
As the valve element 11g approaches the valve seat hole 11d, the flow rate flowing out from the first outlet 11b decreases, and at the same time, the valve body 11g moves away from the valve seat hole 11e, and the flow rate flowing out from the second outlet 11c increases. Conversely, if you rotate the
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 first outlet 11b and the second outlet 11 can be adjusted without changing the flow rate flowing in from the inlet 11a.
The ratio of the flow rate flowing out from c can be changed.

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 washing device A-1 is set by the flow rate control valve 10, and the ratio of the washing water to the surplus water is adjusted by adjusting the distribution valve 11. 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 steel tube with good thermal conductivity, and has a bent tube 13b and a straight tube 13c.

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 sheeter or the like. Further, a positive characteristic thermistor, a platinum-side hot body, a thermocouple, etc. can also be used as the temperature detection part 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.

The spouting part b, which is a feature of the present invention, is installed in a substantially central portion of the case 5 in an oblique manner toward the inside of the toilet bowl 1, as shown in FIG. The details are shown in FIGS. 18 to 22. In this embodiment, the jetting part b is composed of a jetting part main body 26 and a nozzle 27 that is extendable and retractable with respect to the jetting part main body 26. The main body 26 and the nozzle 27 are made of synthetic resin such as ABS resin or polyacetal resin, and are plated if necessary. These 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 communicates with an opening 27c provided on the upper surface of the tip of the nozzle 27 via an inner cylinder 26c, and the other surplus water supply port 26b
A cylindrical chamber 26d is formed between the jetting part body 26 and the inner cylinder 26c, and a small hole 2 is formed in the piston part 27a of the nozzle 27 that slides inside the cylindrical chamber 26b.
7b, it communicates with a discharge hole 26f opened in the distal end surface of the ejection part main body 26 via an annular chamber 26e formed by the main body 26 and the small diameter portion of the nozzle 27. The nozzle 27 is guided by a cylindrical chamber 26d and an inner cylinder 26c and slides within the jetting part main body 26, and a pressure receiving plate 27j with a small hole 27i opened approximately in the center is disposed in a hollow chamber 27h at the tip thereof. It is set up. Further, a nozzle switching tube 27e that can be rotated 180 degrees by operating a knob 27d is fitted on the outer periphery of the tip of the nozzle 27, and is prevented from coming off by a retaining ring 27k. The above-mentioned opening 27 is formed on the vertical side wall of this nozzle switching cylinder 27e.
27 f of ejection holes are opened so as to correspond to c. 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. 27c
It is arranged so that the desired ejection form can be obtained, 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 a positioning ring that is attached to the tip of the main body 26 and has a D-shaped hole that prevents the nozzle 27 from rotating. There is. Further, the nozzle 27 is always urged by the 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 d, the pressure of the surplus water acts on each nozzle 27j, and the nozzle 27 resists the elastic force of the coil spring 27g.
protrudes inward from the toilet bowl 1. Then, the hot water is jetted toward the private parts from the inner cylinder 26c, the hollow chamber 27h of the nozzle 27, the pressure receiving plate 27j, and the desired jet hole 27f of the nozzle switching cylinder 27e to wash the private parts, and the excess water is discharged from the cylindrical chamber 26d, It passes through 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 flows through the small hole 27b.
It passes through the annular chamber 26e and is gradually discharged into the toilet bowl 1 from the discharge hole 26f, and the hot water in the hollow chamber 27h is gradually discharged into the toilet bowl 1 through the small hole 27i of the pressure receiving plate 27j, the opening 27c, and the spout hole 27f. The nozzle 27 is discharged, and the nozzle 27 is contracted again by the elastic force of the coil spring 27g and is housed in the ejection part main body 26. Note that the ejection hole 27f does not need to be switchable as in this embodiment.

Further, although the surplus water is used for expanding and contracting the nozzle 27 and is discharged from the discharge hole 26f of the spout main body 26 to the toilet bowl 1, this surplus water may be used for cleaning the nozzle 27.

The block diagram of the electric circuit of this embodiment is shown in FIG. 23, and the flowchart of the hot water cleaning device A-1 is shown in FIG.
Shown in Figure 4. As shown in FIGS. 2 and 3, the toilet seat 3 controlled by the toilet seat heating device is attached to the sanitary cleaning device body using a pin 5d or the like in a recess 5c provided in the case 5 of the sanitary cleaning device body A together with the toilet lid 4. It is pivotally attached to A so that it can rotate freely.

After using the toilet, to wash your private parts with warm water while sitting on the toilet seat 3, operate the on-off handle 9a and open the on-off valve 9.

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 spray cleaning continues while the on-off valve 9 is open, but even if the hot water previously stored at an appropriate temperature in the heat transfer tube 13 is used up, newly supplied water will continue to be used. While flowing through the heat transfer tube 13, it is efficiently heated by the heating part a-1 such as the planar heating element 23 to become hot water, and the temperature detection part d-1 accurately and quickly detects the temperature of the hot water. , the temperature of the hot water is always kept constant by the cooperative action of the temperature detection section d-1 and the electric control section c-1 that controls energization to the heating section a-1 based on the temperature detection section d-1. Therefore, even if you use it continuously for a long time, the hot water will not get hot or cold.

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 hot air, operate the changeover switch SW to switch to the hot air device A-2. Then, hot water cleaning device A-
At the same time as the heating circuit 1 is de-energized, the heating circuit, motor, etc. of the hot air device A-2 are energized, and the conveying section 34 composed of an electric motor, a sirotskov fan, etc. starts operating, and the nichrome wire, etc. The hot air heated by the heating part a-2 consisting of the heating part a-2 is blown out from the air outlet 33 toward the private part to dry the part, but the heating part a-2
The temperature of the hot air heated by is detected by a temperature detection part d-2 such as a thermistor, and the heating part a-2 is controlled by the cooperative action of this temperature detection part d-2 and the electric control part C-2. , the temperature of the hot air blown out from the outlet 33 is always kept constant. After drying the area, operate the changeover switch SW again to return to the original state.

〔Effect of the invention〕

As explained above, in the present invention, a small hole is formed in the piston part provided at the base end of the nozzle to communicate between the surplus water supply port and the annular chamber, and a small hole is formed in the tip part of the ejection part main body. A discharge hole is provided for discharging the water in the annular chamber around the nozzle. For this reason,
When the nozzle retreats after local cleaning, the water accumulated between the excess water supply port and the piston moves into the annular chamber through the small hole, and the water is discharged around the nozzle through the discharge hole. Ru. Therefore, together with the surplus water discharged from the spout hole when the nozzle retreats, the outer circumferential surface of the nozzle and the tip of the nozzle are cleaned, which is hygienic and, in the past, was simply discharged into the toilet bowl. This makes it possible to use water effectively.
