Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial application field) The present invention relates to a human body local cleaning apparatus.

(Prior Art) Conventionally, this kind of human body local cleaning device is disclosed in
The one disclosed in JP-A-241231 is known. This is disposed between the hot water tank, the bidet cleaning nozzle device and the anal cleaning nozzle device connected to the hot water tank, and the hot water tank and the two nozzle devices. And the bidet cleaning nozzle device or the anal cleaning nozzle device in a communicating state, at the time of non-cleaning operation,
It has two valve mechanisms for a bidet cleaning nozzle and an anal cleaning nozzle that cut off the communication between the hot water tank and the two nozzle devices and that connects the two noise devices to the atmosphere via a drain pipe. Atsuta.

(Problems to be Solved by the Invention) However, usually, after washing is completed, hot water that cannot be completely discharged through the drain pipe remains between the discharge port of the hot water tank including the valve mechanism and the two nozzle devices. Residual water may be cooled when not in use, and may be ejected as cold water at the beginning of the next cleaning. In order to solve this, in the above-mentioned human body local cleaning device, the portion from the outlet of the hot water tank including the valve mechanism to both nozzle devices is provided in or near the hot water tank so that the residual water is not cooled. For this reason,
The capacity of the hot water tank is reduced, and the duration of hot water jetting from both nozzle devices is reduced. In addition, since the layout of the two nozzle devices is determined according to the cleaning position of the human body part, the shape and position of the hot water tank are inevitably restricted, which reduces the degree of freedom in design and reduces the size of the hot water tank. The shape becomes complicated, and a complicated internal water channel is formed in consideration of the flow of the hot water in the hot water tank in order to squirt only the hot water.

Therefore, an object of the present invention is to make it possible to completely discharge hot water between a discharge port of a hot water tank including a valve mechanism after cleaning and the two nozzle devices.

[Configuration of the invention]

(Means for Solving the Problems) The technical measures taken in the present invention to solve the above technical problems are a hot water tank, a bidet cleaning nozzle device and an anal cleaning nozzle device connected to the hot water tank. Disposed between the hot water tank and the two nozzle devices, and in a cleaning operation, the hot water tank and the bidet cleaning nozzle device or the anal nozzle device are in communication with each other. The communication between the tank and the two nozzle devices is cut off in the vicinity of the outlet of the hot water tank, and from the outlet of the hot water tank to the two nozzle devices is brought into communication with the atmosphere, and the two nozzle devices are connected via a drain pipe. The valve mechanism for communicating with the atmosphere and the shutoff near the discharge port of the hot water tank include a valve body that cuts off communication between the discharge port and the connection pipe by introducing air. The pipe is connected between the valve mechanism and the valve body, and is a human body local cleaning device. (Function) The above technical means operates as follows. After washing,
By operating the valve mechanism, the space from the discharge port of the hot water tank to both nozzle devices is brought into communication with the atmosphere, and the atmosphere is introduced. As a result, the hot water from the outlet of the hot water tank to the two nozzle devices is pushed by the atmosphere and is completely discharged from the front end portions of the two nozzle devices.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, hot water is supplied to a supply port 2 formed at a lower portion of a hot water tank 1 by a connecting pipe 3 and guided to an upper portion of the hot water tank 1 via a vacuum breaker mechanism 4 provided at an upper portion of the hot water tank 1. It is connected to a water supply pipe 5 opening at the lower part of the tank 1. The valve body of this bakyumu breaker mechanism 4
4a normally shuts off the communication between the connecting pipe 3 and the water supply pipe 4 by introducing air. A discharge port 6 formed in the upper part of the hot water tank 1 is connected to a bidet cleaning nozzle device 7 and an anal cleaning nozzle device 8 via a valve mechanism 20. The supply port 2 is connected to a water supply source (not shown) by connecting pipes 9 and 10 via a valve mechanism 20. The connecting pipe 10 is provided with an electromagnetic valve 11 and a pressure regulating valve 12.

A jet port 16 is formed at the other end of 15 (the tip of the nozzle 12). The nozzle 14 forms a minute gap between the periphery of the piston 14a and the inner wall of the cylinder 13 and between the tip of the cylinder 13 and the piston 14a, i.e., the passage 15 when the nozzle 14 on the inner wall of the cylinder 13 is washed. A cutout portion 17 is formed at a position where the open end of the is located. Also, cylinder
A spring 18 is provided between the nozzle 13 and the nozzle 14, and the nozzle 14 is constantly urged to be in the housed state by the urging force of the spring 18.

 Next, the valve mechanism 20 will be described.

As shown in FIG. 1 to FIG.
Inside, a valve body 35 is rotatably arranged, and this valve body 35 is connected to a motor 36. A disc that rotates integrally with the valve body 35
37 is fixed, and the disk 37 faces an optical sensor 38 disposed near the motor 36. The rotation of the disc 37 turns the optical sensor ON / OFF (detects the rotation of the valve body 35), and the switching point is set as the rotation reference position of the motor 36.

The housing 21 has inlets 22, 22 and outlets 24, 25, 26, 27, 2
8 are formed respectively. The discharge port 25 and the discharge port 26 and the discharge port 27 and the discharge port 28 are formed to face each other by 180 degrees with the valve body 35 interposed therebetween.

The supply port 22 is connected to the connection pipe 10, and the supply port 23 is connected to the discharge port 6 of the hot water tank 3 via the connection pipe 29 and the vacuum breaker mechanism 30. The valve body 30a of the buckyme breaker mechanism 30 normally closes the discharge port 6 by the introduction of the atmosphere to cut off the communication between the discharge port 6 and the connecting pipe 29. Discharge port 24
Is connected to the connecting pipe 9, the discharge port 25 is connected to the supply port 19 of the bidet cleaning nozzle device 7 via the connecting pipe 31, and the discharge port 26 is connected to the supply port 19 of the anal cleaning nozzle device 8 via the connecting pipe 32. The discharge port 27 is connected to a drain pipe 33 opened near the tip of the cylinder 13 of the bidet cleaning nozzle 7, and the discharge port 28 is connected to the drain pipe opened near the tip of the cylinder 13 of the anal cleaning nozzle 8. Each is linked to 34.

The valve body 35 is formed with a triangular through hole 39 whose cross-sectional area changes in the rotation direction, and communicates with the supply port 22 through a passage 40 formed in the valve body 35. A bidet washing passage 41 and an anal washing passage 42 are formed in the housing 21 so as to be opposed to each other by 180 degrees with the valve body 35 interposed therebetween so as to be able to communicate with the through hole 39. The bidet washing passage 41 and the anal washing passage 42
Communicates with the discharge port 24 through the passage 43.

A slit 44 communicable with the discharge ports 25 and 26 is provided in the valve body 35 at the same position as the through hole 39 in the axial direction of the valve body 35 and the valve body 35.
In the circumferential direction of 35, it is formed with the same length as the through hole 39. A bidet washing passage 45 and an anal washing passage 46 are formed in the housing 21 so as to be able to communicate with the slit 44 in the same axial direction as the discharge ports 25 and 26 by 180 degrees with the valve body 35 interposed therebetween. The bidet washing passage 45 and the anal washing passage 46 are in communication with the inlet 23 through a passage 47.

The valve body 35 has two slits 48 and 49 which can communicate with the discharge ports 25 and 28, the bidet cleaning passage 45 and the discharge ports 26 and 28, and the anal cleaning passage 46 with respect to the through hole 39 and the slit 44. They are formed 180 degrees opposite each other at positions shifted by 90 degrees. Incidentally, the valve body 35 is usually positioned so that the through hole 39 and the slits 44, 48, 49 do not communicate with any passage, and this position is a rotation reference position of the motor 36.

As described above, the switching function of the two cleaning nozzles 7 and 8 is provided integrally with the flow rate adjustment function to the hot water tank 1 and configured as one valve mechanism 20, so that two electromagnetic valves are not required unlike the related art. This is cost effective. Also, since the sealing location is concentrated at one location of the valve mechanism 20, it is advantageous in reliability and maintenance.

 Next, the operation will be described.

In FIG. 1, when performing anal irrigation, the motor 21 is operated to rotate the valve body 35, and the state shown in FIGS. 3 to 7, ie, the through hole 39 and the anal irrigation passage 42, The cleaning passage 46 and the discharge port 26 are in communication with each other,
The slit 48, the discharge ports 25, 27 and the bidet cleaning passage 47,
The slit 49 disconnects the discharge ports 26 and 28 and the anal washing passage 46 from each other. Immediately after this, when the solenoid valve 11 is opened, cold water is supplied to the supply port 22 via the connecting pipe 10. The cold water supplied to the supply inlet 22 passes through the through hole 39 via the passage 40, the anal washing passage opening 22, the discharge opening 24, and the connecting pipe 9.
Is supplied to the supply port 2 via the. The chilled water supplied to the supply port 2 reaches the buckyme breaker mechanism 4 via the connecting pipe 3, and the water pressure pushes and opens the valve body 4 a to establish a communication state between the connecting pipe 3 and the water supply pipe 5. It is supplied to the lower part of the hot water tank 1 via the water supply pipe 5. Thereby, the cold water supplied to the lower portion of the hot water tank 1 by the action of the heater (not shown) becomes hot water, and the hot water located at the upper portion of the hot water tank 1 is extruded from the discharge port 6 by the pressure of the cold water supply. .

The hot water extruded from the discharge port 6 is supplied to the bakyu breaker mechanism 30. The valve body 30 is pushed open by the pressure of the supplied hot water, so that the discharge port 6 and the connection pipe 29 are in communication with each other, and the hot water is supplied to the supply port 23 via the connection pipe 29. The hot water supplied to the supply port 23 is supplied to the discharge port 26 through the slit 44 via the passage 47 and the anal cleaning passage 46. The hot water supplied to the discharge port 26 reaches the inlet 19 of the anal cleaning nozzle device 8 through the connecting pipe 32 and is supplied into the cylinder 13.

The hot water supplied into the cylinder 13 causes the nozzle 14 to extend from the storage position to the cleaning position by the action of the piston portion 14a against the urging force of the spring 18 by the action of the piston portion 14a due to the water pressure, and the notch 17 in the cleaning state. It is supplied to the passage 15 through. Thereby, the hot water is spouted from the spout 16 in the cleaning state of the nozzle 14, and the human body part is cleaned.

When the washing is completed, the electromagnetic valve 11 is closed, the supply of the cold water is shut off, the pressure in the water circuit decreases, and the nozzle 14 moves backward from the washing position to the storage position by the urging force of the spring 18. Simultaneously with the closing operation of the solenoid valve 11, the motor 10 operates to rotate the valve body 35, and the state shown in FIGS. 9 to 13, namely, the slit 48, the discharge ports 25 and 27, and the bidet cleaning passage 47
The slit 49 is connected to the discharge ports 26, 28 and the anal cleaning passage 46.
Are in communication with each other, and the penetration hole 39 and the anal cleaning passage 42 are not in communication with the slit 44, the anal cleaning passage 46 and the discharge port 26, respectively. The hot water in the cylinder 13 is extruded by the retreat of the nozzle 14 described above, and the extruded hot water flows back through the supply port 19 and the connecting pipe 32 and is supplied to the discharge port 26.
The hot water supplied to the discharge port 26 passes through a slit 49, is supplied to the discharge port 28, and is discharged to the tip of the cylinder 13 via a drain pipe 49. As a result, the retreating nozzle 14 is cleaned.

When supplying the cold water to the hot water tank 1 described above, since the hot water tank 1 is made of resin, a slight deformation occurs due to the water pressure, and when the supply of the cold water is stopped, the hot water tank 1 is closed. Remains deformed, the residual water pressure is generated due to the deformation, but after the supply of the cold water is stopped, the valve body 35 is rotated to the state shown in FIGS. The cleaning passage 47 is in communication with the cleaning passage 47, and the residual water pressure is transmitted from the discharge port 6 to the connecting pipe 29 and the supply port 2 by the action of the vacuum breaker mechanism 30.
3. The air is discharged to the atmosphere via the passage 47, the bidet cleaning passage 45, the slit 48, the discharge port 27, and the drain pipe 33. Thereby, the pressure in the hot water tank 1 is surely reduced, and after the supply is stopped, the hot water tank 1 is not deformed, and the hot water tank 1 is advantageous in durability.

Thereafter, when the nozzle 15 is completely housed and the water pressure in the water circuit, the nozzle devices 7 and 8 and the hot water tank 1 is completely eliminated, the valve elements 4 of the vacuum breaker mechanisms 4 and 40 are stopped.
a and 30a completely shut off the communication between the connection pipe 3 and the water supply pipe 5 and the communication between the discharge port 6 and the connection pipe 29 in response to the introduction of the atmosphere.
The outflow of hot water in the hot water tank 1 due to the siphon phenomenon can be prevented by interrupting the communication between the connection pipe 3 and the water supply pipe 5 by introducing air into the buckyme breaker mechanism 3.
In addition, by introducing the atmosphere of the bakyume breaker mechanism 3,
The air is supplied to the connecting pipe 29, the supply port 23, the passage 47, the bidet washing passage 45 and the anal washing passage 46, the slits 48, 49, and the discharge ports 25, 2.
6, through the inlet 19, it flows out into both nozzle devices 7,8. For this reason, the nozzles 7, 8
The passage to is related to being horizontal or inclined,
The residual water in the inside is completely discharged from the gap between the tip of the cylinder 13 and the nozzle 14 and the jet port 16. When performing bidet cleaning, the valve body 35 is inserted into the through hole 39 and the bidet cleaning passage.
It is performed by rotating so that it is in communication with 41, and the subsequent operation is the same as that of anal irrigation.

Thus, in order to completely discharge the residual water in both nozzle devices 7, 8 and the valve mechanism 20 after the end of the cleaning by introducing the air,
It is possible to prevent the cold water from being blown out at the initial stage of the next cleaning due to the cooling of the residual water, thereby improving the cleaning free ring and preventing freezing at a low temperature. Further, since the residual water is completely discharged to prevent the cold water from being ejected at the initial stage of the next washing, the nozzle circuits 7, 8 and the valve mechanism 20 and the water circuit around the nozzle device are placed in or near the hot water tank 1. There is no need to provide the hot water tank 1, and the volume and the shape of the hot water tank 1 are not restricted, and a relatively simple shape can be obtained. Thus, the degree of freedom in designing the hot water tank 1 is increased, and the internal water channel structure for extruding only hot water from the discharge port 6 can be made relatively simple.

The valve mechanism 6 may be directly attached to the hot water tank 1 and the connecting pipes 9 and 29 therebetween may be omitted, thereby preventing the temperature of the hot water at the connecting pipes 9 and 29 from dropping during washing. The cleaning free ring can be further improved. 14 to 17
As shown in the figure, the valve body 35 may make a sliding motion.

〔The invention's effect〕

The present invention provides a hot water tank, a bidet cleaning nozzle device and an anal cleaning nozzle device connected to the hot water tank, and is disposed between the hot water tank and the two nozzle devices. The tank and the bidet cleaning nozzle device or the anal nozzle device are in communication with each other, and during non-cleaning operation, the communication between the hot water tank and the nozzle devices is cut off near the discharge port of the hot water tank and the hot water tank is closed. A valve mechanism for bringing both the nozzle devices into communication with the atmosphere from the discharge port to the two nozzle devices and communicating the two nozzle devices with the atmosphere via a drain pipe, and the shutoff near the discharge port of the hot water tank is performed under the atmosphere. And a valve body that cuts off communication between the discharge port and the connection pipe by introducing the valve, wherein the connection pipe is connected between the valve mechanism and the valve body. To Since form was, washed completion, the ZanTsuta of hot water from the discharge port of the hot water tank to both the nozzle device can be completely discharged from the tip portions of the nozzle device by pressing by air. Thus, it is possible to prevent the cold water from being blown out at the initial stage of the next cleaning due to the cooling of the residual water, thereby improving the cleaning free ring and preventing freezing at a low temperature.
Further, since it is not necessary to provide both nozzle devices, the valve mechanism and the water circuit around the nozzle device in or near the hot water tank,
The hot water tank can be formed into a relatively simple shape without any restrictions on the volume and shape. As a result,
The degree of freedom in designing the hot water tank increases, and the internal water channel structure for pushing out only hot water from the discharge port can be made relatively simple.

At the same time as discharging the residual water from the connecting pipe, the washing water for nozzle cleaning is used without waste, and there is no need to newly supply water from the hot water tank, so the washing water in the hot water tank is wasted accordingly. Without having to do so, the supply of heat to the washing water, which is always supplied from the tap water to the hot water tank to a constant level for the reduced washing water, is also eliminated, which is effective for energy saving.
