It moves forward and backward. The supply of cleaning water and the operation of the nozzle body 53 are controlled by the control unit 1e. All controlled by.

[0005] The nozzle body 53 is advanced to the cleaning position by the drive motor 54, and the cleaning water is directed to the tip. The liquid is ejected from the nozzle head 53a to cleanse the private parts. And such cleaning If dirt, etc. adheres to the nozzle head 53a during processing, it is automatically removed. Therefore, a mechanism is provided for cleaning the nozzle head 53a by spraying it with cleaning water. It will be done.

[0006] Various types of cleaning mechanisms are used for this cleaning mechanism, but as shown in Figure 9, A cleaning pipe 1g is branched from the three-way switching solenoid valve 1d, and a cleaning head is installed at the tip of the cleaning pipe 1g. There is one with 1h. The cleaning head 1h has a nozzle body 53 for cleaning. After returning from the position and being stored in the cylinder 52, the valve unit 1b is transferred to the control section 1e. Washing water is supplied for a certain period of time under better control, washing the circumferential surface of the nozzle head 53a. Flow.

[0007] In addition to cleaning by the cleaning head 1h, there is Cleaning is performed by spouting cleaning water from the nozzle head 53a using the provided flow path. There are some things. This means that when the nozzle body 53 is stored after cleaning the private area, the nozzle A chamber enclosing the head 53a is provided on the casing 1 side, and the nozzle head The cleaning water discharged from 53a is temporarily stored in this chamber and sent to the nozzle. The structure is such that the peripheral surface of the pad 53a is washed away.

For this reason, conventionally, the circumference of the nozzle body 53a is A gasket for squeezing the surface and removing adhering water is installed at the inlet at the tip of the cylinder 52. A structure was adopted in which it was incorporated into, etc.

[0009] However, the nozzle body 53 receives frictional resistance from the cylinder 52. In addition, resistance due to the sealing pressure of the packing also acts. Therefore, the output of the drive motor 54 is It is necessary to have some margin for force and torque, and if the packing is not installed properly, This affects the quick operation of the nozzle body 53.

0010 In addition, in order to incorporate the packing into the tip of the cylinder 52, it is necessary to fit the packing into the cylinder 52. A structure in which a groove is cut into the inner periphery of the cylinder 52 or another member is used to receive the packing. Must be. For this reason, not only the packing but also the cylinder 52 side is processed. Even if the structure can be simplified, there is a limit as it requires additional components. be.

[0011] In this way, the structure uses the packing to squeeze out the water adhering to the cylinder 52. In addition to the possibility of affecting the movement of the nozzle body 53, the number of parts and assembly may The number of man-hours required for setup will increase.

0012 The problem to be solved with this invention is that the washing water for cleaning is the base of the nozzle body. The purpose is to simplify the structure to prevent the end from entering.

[0013]

[Means to solve the problem]

This invention features a nozzle body that is arranged so that it can move back and forth between the storage position and the cleaning position. , Cleaning that covers the nozzle head at the tip of the nozzle body in its storage position. a chamber, and the cleaning water is supplied to the cleaner from a jet hole formed in the nozzle head.

Figure 1 is a right side view showing the nozzle device of the present invention, Figure 2 is its top view, and Figure 3 is the nozzle. FIG. 4 is a left side view showing the distal end portion of the device, and FIG. 4 is a front view of the distal end portion.

[0016] As shown in FIG. 8, the sanitary cleaning device is housed in a casing 1 and a toilet body 5. 0, and a cleaning water supply system shown in FIG. 5 is provided inside the casing 1. . This is a valve unit with an on-off valve and pressure regulating function, similar to the one shown in Figure 9. 1b, a heating tank 1c, and a control section 1e, the heating tank 1c and a nozzle to be described later. A flow rate adjustment switching unit 1i is installed between the flow rate adjustment and switching unit 1i. This flow rate adjustment is turned off. The replacement unit 1i is equipped with an inflow part and two outflow parts from the heating tank 1c. , an on-off valve mechanism that opens and closes the flow paths to these outflow sections separately and adjusts the flow rate of each. It has a configuration that incorporates a flow rate adjustment valve that can be used in the flow path system of general water equipment. This is what is used. Then, drive the nozzle device, set the cleaning position, and heat the nozzle device. Setting of hot water temperature of tank 1c, valve unit 1b and flow rate adjustment switching unit 1i is operated by the operation part 1a provided in the casing 1, as in the case of FIG. cormorant.

[0017] As shown in FIGS. 1 to 4, a base 2 of the nozzle device is fixed inside the casing 1. A nozzle body 3 is incorporated into this base 2 so as to be movable in its axial direction. There is. The base 2 is a concave slide that receives the lower surface of the pipe-shaped nozzle body 3. A surface 2a is formed on the tip for washing the nozzle head 4 of the nozzle body 3. A cleaning chamber 2b is provided. In addition, a drive motor is provided on the base end side of the base 2. A motor 5 is fixed, and a drive pulley 5a is provided on its output shaft. And this drive A timing belt 6 is wound around the pulley 5a, and two pulleys provided on the base 2 are connected to each other. This timing belt 6 is wrapped around 5b, 5c and tension pulley 5d. Ru.

[0018] As shown in Fig. 6, the nozzle body 3 has two channels formed inside, one of which is used for anal washing. A first flow path 3a is used for cleaning, and the other is a second flow path 3b for bidet use. So Then, a job is established to connect the two supply pipes 7a and 7b from the flow rate adjustment switching unit 1i. The points 3c and 3d are pushed sideways from the proximal ends of these first and second channels 3a and 3b. (Figure 2). A timing belt is attached to the circumferential surface of the base end of the nozzle body 3. A clamp 3e is provided to grip the nozzle body 3 as the timing belt 6 runs. move. In addition, in order to follow the movement of the nozzle body 3, the supply pipes 7a, 7b is flexible.

[0019] The nozzle head 4 has a nozzle body 3 housed in a casing 1 as shown in Figure 1. Sometimes, it has an axial length that fits within the cleaning chamber 2b. And inside is divided into two chambers, one of which communicates with the first flow path 3a of the nozzle body 3 and has a hole on the top for anal cleaning. The first jet hole 4a is opened, and the other one communicates with the second flow path 3b and is used as a bidet on the top surface. A second ejection hole 4b is provided.

[0020] When using the first jet hole 4a, the rotation amount of the output shaft of the drive motor 5 is controlled by the control unit 1e. Therefore, the setting is such that the cleaning water from the flow rate adjustment switching unit 1i is also directed only to the supply pipe 7a side. Can be switched. Also, in the case of using the second jet hole 4b, the nozzle body 3 is also The low angle is set to be large, and the supply of cleaning water is also switched to the supply pipe 7b side.

[0021] FIG. 7 shows details of the cleaning chamber 2b, and (a) in the same figure shows a flat view. A top view, (b) of the same figure is a cutaway side view, and (c) of the same figure is a view taken along the line A-A in (b). FIG.

[0022] The cleaning chamber 2b is integrally formed on the extension of the base 2a, and is shown in FIG. As shown in c), it has an inverted U-shaped vertical cross section with an open bottom end. And at the tip has a cutout to pass the nozzle head 4 through, and when the nozzle body 3 is stored, 6, the entire nozzle head 4 is enclosed in the cleaning chamber 2b. be caught. In addition, inside the cleaning chamber 2b, there is water for cleaning. A baffle plate 2c is provided to prevent the liquid from flowing into the sliding surface 2a side of the base 2. this As shown in FIG. 7(c), the baffle plate 2c is located approximately in the upper half of the cleaning chamber 2b. The nozzle body 3 is provided in a vertical direction so as to take up the area, and the part where the nozzle body 3 moves has a semicircular A shaped notch 2d is formed. The baffle plate 2c is connected to the nozzle as shown in FIG. When the main body 3 is stored, it is located at a position biased toward the proximal side of the first ejection hole 4a. between the back side of the baffle plate 2c and the inner wall of the cleaning chamber 2b and to the nozzle. A water sealing portion 2e is formed between the pad 4 and the circumferential surface of the pad 4.

[0023] In the above configuration, when the anal cleaning switch of the operation section 1a is turned on, the drive motor The drive pulley 5a is rotated by the motor 5, causing the timing belt 6 to run, and The nozzle body 3 is advanced to a stroke of . After this, wash water is supplied from the supply pipe 7a. When it is fed, it flows into the nozzle head 4 from the first flow path 3a, and the first jet for cleaning the anus flows into the nozzle head 4 from the first flow path 3a. Washing water is sprayed from the outlet 4a. When cleaning is complete, press the stop switch to close the valve. The supply of cleaning water from the unit 1c is stopped, and the output shaft of the drive motor 5 is reversed. Then, return the nozzle body 3 to the stored state shown in FIG. After this, the supply pipe 7a is refilled. When cleaning water is sent into the cleaning chamber 2b, this The liquid is ejected from the first ejection hole 4a of the oil head 4. The sprayed cleaning water cleans It bounces off the inner wall of the chamber 2b and flows along the circumferential surface of the nozzle head 4. Wash away any dirt, etc. that has adhered to it.

[0024] The same applies when using the second jet hole 4b, and the stroke of the nozzle body 3 After cleaning, move the nozzle head 4 to the cleaning channel. Wash it off in Bath 2b. Note that the nozzle head 4 in the cleaning chamber 2b Cleaning is performed by simultaneously supplying water from the two supply pipes 7a and 7b to the first and second jet holes. Cleaning water may be spouted from 4a and 4b.

[0025] As mentioned above, cleaning of the nozzle head 4 is performed using the cleaning chamber. This is done when it is stored in 2b. At this time, the first ejection hole 4a or the second ejection hole Since the cleaning water is sprayed from 4b toward the inner wall of the cleaning chamber 2b, The water overflowing in the leaning chamber 2b tries to flow out to the nozzle body 3 side. On the other hand, the baffle plate 2c provided on the inner wall of the cleaning chamber 2b prevents water from flowing through the nozzle. Prevents movement toward the main body 3 side. Also, the first jet hole 4a is directed toward the baffle plate 2c. However, the water that reaches the rear side of the baffle plate 2c stagnates in the water sealing part 2e. Then, the liquid flows downward and washes away the circumferential surface of the nozzle head 4. In addition Of course, the same effect can be obtained even if a plurality of baffle plates 2c are provided.

[0026] In this way, since the baffle plate 2c is provided inside the cleaning chamber 2b, When cleaning the nozzle head 4, water may flow out to the nozzle body 3 side. do not have. Therefore, it is necessary to place the nozzle body 3 exposed on the base 2 and slide it. Even if the structure is such that cleaning water may enter the inside of the casing 1. This prevents damage to the drive motor 5 and other equipment. Also, follow Since there is no need to provide packing as in the past, the sliding resistance given to the nozzle body 3 is also reduced. It becomes smaller and moves faster. In addition, a cleaner is used to incorporate the packing. Cut a groove on the inner periphery of the packing chamber 2b or assemble a new member to receive the packing. The simple structure prevents water leakage during cleaning. Ru.

[0027]

[Effect of the idea]

In this invention, a baffle plate installed on the inner wall of the cleaning chamber prevents water from flowing from the spout hole. This prevents water from entering the casing etc. as it prevents water from flowing towards the base end of the nozzle body. is prevented. Also, even if the baffle plate is not in close contact with the circumferential surface of the nozzle head, Water becomes stagnant in the water seal in the rear space and flows down, causing the water flow to become Intrusion is more effectively prevented. Therefore, packing is not included in the conventional method. The nozzle body moves quickly, and the cleaning channel is no longer necessary. The structure of the bar is also simplified, making it possible to reduce the number of parts and assembly man-hours.
