Detailed Description of the Invention [Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human body local cleaning device.

2. Description of the Related Art Conventionally, as this type of human body local cleaning apparatus, one disclosed in Japanese Patent Laid-Open No. 63-241231 is known. This is a cylinder, a nozzle slidably supported in the cylinder so that it can be stored and used, and a spring that is arranged between the cylinder and the nozzle to constantly urge the nozzle to the stored state. And a water supply source which is connected to the rear end of the cylinder and is supplied into the cylinder and the nozzle. In this conventional device, when the water is supplied from the supply source into the cylinder when the nozzle is in the housed state, the nozzle slides into the used state against the biasing force of the spring by the water pressure of the supplied water, When the nozzle is in use, the water supplied to the cylinder is further supplied to the nozzle. As a result, the water supplied from the ejection port formed at the front end of the nozzle is ejected to wash the human body part. Also, when the nozzle is in use,
When the supply of water from the supply source is cut off, the nozzle slides due to the urging force of the spring and becomes the stored state.

However, in the above-described apparatus for cleaning a human body part, the force between the nozzle and the cylinder for moving the nozzle in the housing direction by the spring and the force for holding the nozzle in the housing position (spring force). When the nozzle slides from the stored state to the used state when the water pressure of the water supplied from the supply source is low, the nozzle is moved by the spring in the storage direction because a large force (urging force) is constantly acting. There was a risk that the force would hinder and the nozzle might stop halfway without completely sliding into use. In addition, when the force for moving the nozzle in the storage direction by the spring is reduced in order to eliminate the above-mentioned problems, when the nozzle slides from the used state to the stored state,
Due to the residual pressure of water remaining in the cylinder, the nozzle may not be completely slid into the stored state. Therefore, the present invention has its technical problem to ensure that the nozzle is slid into the stored state and the used state.

[Constitution of the invention]

The technical means taken in the present invention to solve the above-mentioned technical problem is a cylinder and a slidable support so that the cylinder can be stored and used. Nozzle, a spout formed at the front end of the nozzle, and a water supply for slid the nozzle formed at the rear end of the cylinder from the stored state to the used state and spout from the spout A first supply port connected to the water source and a second supply port formed at the front end of the cylinder and connected to the water source for sliding the nozzle from the used state to the stored state. Noz having
Le device a pair are arranged, the second supply port of one of the nozzle device
And the second supply port of the other nozzle device forms a common passage.
So that water can be simultaneously supplied to both second supply ports via
Connected to the source .

According to the above technical means, the nozzle is slid from the stored state to the used state by the driving force of the water supplied from the supply source to the first supply port, and the water is moved to the front end of the nozzle. It is ejected from the formed ejection port and used for cleaning the human body part. On the other hand, the driving force of the water supplied from the second supply port causes the water to slide from the used state to the stored state, and this water is discharged to the outside from the gap between the nozzle at the front end of the cylinder and the nozzle is washed. Used for. As a result, the force constantly acting between the nozzle and the cylinder can be made small only to hold the nozzle in the stored state, and as a result, the nozzle can be reliably slid into the stored state and the used state. . At the same time, it is possible to wash the nozzle after use by using water as a driving force for sliding the nozzle into the stored state.

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, a toilet seat device 6 including a case 2, a toilet seat 3 and a toilet lid 4 in which a human body local cleaning device 5 described later is incorporated is placed on the upper part of the toilet 1. As shown in FIGS. 2 and 3, the human body local cleaning device 5 is supplied to the nozzle device 7 and the nozzle device 7 supported in the case 2 and extended in the toilet 1 and arranged in the case 2. It basically comprises a hot water tank 8 for storing hot water. The nozzle device 7 is composed of a cylinder 9 and a nozzle 10 slidably supported in the cylinder 9. The cylinder 9 has a cylindrical shape and has a large diameter portion 9a.
And a small diameter portion 9b. The nozzle 10 has a cylindrical shape having a passage 10a inside, and a jet port 10b communicating with the passage 10a is formed at the front end. A piston portion 10c having a diameter substantially the same as the large diameter portion 9a of the cylinder 9 is formed at the rear end. An opening hole 9c through which the nozzle 10 is inserted is formed at the front end of the cylinder 9, and the opening hole 9c is formed slightly larger than the diameter of the nozzle 10 so that a predetermined gap 1 is formed between the opening hole 9c and the nozzle 10.
1 is formed. Also, the front end of the cylinder 9 and the nozzle 1
A spring 12 is arranged between the No. 0 piston portion 10c and the nozzle 10 and is constantly biased to a storage state described later by receiving the biasing force of the spring 12. A cap 13 is fixed to the rear end of the cylinder 9 via a seal member 14. This cap 13 has a cylinder 9
A first supply port 15 communicating with the inside is formed, and
A second supply port 16 communicating with the inside of the cylinder 9 is formed in the small diameter portion 9b of the cylinder 9. The first supply port 15 is connected to the hot water tank 8 via the first passage 17. The hot water tank 8 is connected to the water pipe 19 via the second passage 18 by the branch plug 20. The first passage 17 is operated by a solenoid to open and close the first passage 17 so that the hot water tank 8 and the nozzle device 7 can communicate with each other through the first supply port 15, and the nozzle device 7 and the drain 21 can be connected to each other. A three-way switching valve 22 that allows communication with the first supply port 15 is provided. A water shutoff valve 2 that is operated by a solenoid in the second passage 18 to open and close the second passage 18 to allow the water pipe 19 and the hot water tank 8 to communicate with each other.
3 are provided. The second supply port 16 is the third passage 2
4 is connected between the water pipe 19 of the second passage 18 and the water shutoff valve 23. An opening / closing valve 25, which is operated by a solenoid to open / close the third passage 24 and allows the third passage 24 and the nozzle device 7 to communicate with each other through the second supply port 16, is arranged in the third passage 24. It is set up. Next, the operation will be described. Normally, the three-way switching valve 22 is switched so that the nozzle device 7 and the drain 21 communicate with each other through the first supply port 15, and the opening / closing valve 25 is in the closed state and the nozzle device 7 and the second passage 18 are connected. Communication with has been cut off.
Further, with the water shutoff valve 23 open, the water pipe 1
The water supplied from 9 is made hot water by a heater (not shown) in the hot water tank 8 and is stored in the hot water tank 8. Further, the nozzle 9 of the nozzle device 7 has a spring 12
It is held in a housed state in contact with a cap 13 arranged at the rear end of the cylinder 9 by receiving the urging force of. In this state, when the three-way switching valve 22 is operated so that the nozzle device 7 and the warm water tank 8 communicate with each other, the warm water stored in the warm water tank 8 is supplied to the first passage 17 and the first supply port 1.
It is supplied into the cylinder 9 via 5. As a result, the spring 1 is driven by the water pressure of the hot water supplied to the nozzle 10.
The sliding of the cylinder 9 against the urging force of 2 causes the step between the large-diameter portion 9a and the small-diameter portion 9b of the cylinder 9 to come into contact with the piston portion 10c, that is, the nozzle 10 extends and extends from the cylinder 9. It becomes a state. When the nozzle 10 is in use, the hot water supplied into the cylinder 9 is supplied into the passage 10a of the nozzle 10 and finally ejected from the ejection port 10b to the outside. As a result, the human body part is cleaned. After use, when the three-way switching valve 22 is operated so that the nozzle device 7 and the drain 21 are in communication with each other and the opening / closing valve 25 is operated in the open state, the water flowing through the second passage 18 becomes It is supplied into the cylinder 9 through the second supply port 16. As a result, the nozzle 10 slides in the opposite manner to the above due to the water pressure of the supplied water, and the usage state is changed to the storage state. At this time, the warm water supplied from the first supply port 15 into the cylinder 9 is drained through the first supply port 15 to the drain 21.
Is surely discharged. As a result, the warm water supplied from the first supply port 15 does not remain in the cylinder 9 and the nozzle 10, and the initial cold water is prevented from being jetted at the time of the next use. When the nozzle 12 is stored, the on-off valve 25
Is closed and the communication between the second passage 18 and the nozzle device 7 is cut off. The water supplied from the second supply port 16 into the cylinder 9 is discharged to the outside through the gap 11 around the nozzle 9. In this way, the sliding of the nozzle 12 from the used state to the stored state is performed by the water pressure of the water supplied from the second supply port 16 into the cylinder 9, so that the nozzle 12 is surely slid into the stored state. Further, the force constantly acting between the nozzle 10 and the cylinder 9 is small only by the force of the spring 12 which holds the nozzle 10 in the housed state. Accordingly, when the nozzle 10 slides from the stored state to the used state, a large force that hinders the sliding is applied to the nozzle 10.
The nozzle 10 is surely slid into the use state since it does not work. Since the spring 12 holds the nozzle 10 in the housed state, as shown in FIG. 6, magnetic members 28 and 29 are arranged on the piston portion 10c and the cap 13 of the nozzle 10, respectively. ,
The suction force of 29 may hold the nozzle 10 in the housed state. Furthermore, when the nozzle 10 slides into the housed state, the nozzle 10 can be washed with water supplied from the second supply port 16. The water that slides the nozzle 10 from the use state to the storage state is the hot water tank 8.
Since it is obtained from the second passage 18 located further upstream,
It is economical to avoid the use of the hot water stored in the hot water tank 8 for purposes other than the original purpose of washing the human body part, and it is economical and the use of water when the nozzle 10 slides from the used state to the stored state. Therefore, no pressure is applied to the hot water tank 8. As shown in FIG. 4, the third passage 24 may be connected between the hot water tank 8 of the second passage 18 and the water shutoff valve 23. As a result, in addition to the above-mentioned advantages, when the human body part cleaning device 5 is not used, the water pressure is not applied to the opening / closing valve 25 by closing the water shutoff valve 23. Also, as shown in FIG. 5, the first passage 17
It may be connected between the hot water tank 8 and the three-way switching valve 22. As a result, the handling of the third passage 24 is simplified and space is saved, and hot water is used to move the nozzle 10 to the stored state, and the cleaning effect of the nozzle 10 at that time is further improved. Furthermore, the on-off valve 25
Is operated by a solenoid to open and close the third passage 24 to connect the second passage 18 or the first passage 17 and the nozzle device 7 to the second supply port 16 as shown in FIGS.
Through the nozzle device 7 and the drain 2
6 may be a three-way switching valve 27 that can communicate with each other via the second supply port 16. As a result, the second supply port 1
The water supplied from 6 to the cylinder 9 is surely drained 27
It is not drained to the cylinder 9 and remains in the cylinder 9, and this water does not hinder the sliding of the nozzle 12 from the housed state to the used state. FIG. 7 shows an example in which there are two nozzle devices 7, one is a nozzle device 30 for a bidet and the other is a nozzle device 31 for a shower.
The supply ports 16 are connected by a common third passage 32. As a result, even if the two nozzle devices 30 and 31 are used, the human body local cleaning device 5 can be configured with the same number of parts as in the case of the single nozzle device 5, and in terms of assemblability and cost. It will be very advantageous.

According to the present invention, the front end of the cylinder is provided with the second supply port communicating with the supply source of water for sliding the nozzle from the used state to the stored state. Since the nozzle is slid from the used state to the stored state by the driving force of water, the force that constantly acts between the nozzle and the cylinder should be small enough to hold the nozzle in the stored state. As a result, the nozzle can be surely slid into the stored state and the used state.
