Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sanitary cleaning device that has an internal cleaning function and is disposed in a flush toilet bowl.

[Conventional technology]

Conventionally, sanitary cleaning devices that spray cleansing water from a cleansing nozzle to private parts include a hot water tank that heats and stores cleansing water in a casing that is fixed to the toilet body, a valve unit that supplies cleansing water, and a valve unit that sprays cleansing water to private parts. The configuration includes a nozzle device, control equipment for controlling these devices, etc., and the operating section is provided with a water force adjustment knob linked to the valve unit in order to change the amount of cleaning water jetted from the nozzle device.

Then, the rotation of this knob is transmitted to the needle valve of the valve unit by the drive shaft, and the water flow of the cleaning water is adjusted by increasing or decreasing the area of the cleaning water flow path in the valve unit by rotating the needle valve back and forth. It is configured to do this.

[Problem that the invention attempts to solve]

The water force of this washing water is adjusted from stopping the supply to the maximum water force within one rotation of the knob, but since the drive shaft itself is not equipped with a stopper etc., it rotates without stopping at one rotation. do.

Therefore, if you accidentally turn the knob too much during operation,
There is a problem in that the valve body of the needle valve reaches a position beyond its movement range and becomes locked, making it impossible to operate even if the knob is turned, making it impossible to adjust the water pressure.

The purpose of the present invention is to prevent the needle valve from locking by regulating the rotation of the rotary drive shaft that adjusts the water force by the water force adjustment knob.

[Means and actions for solving problems]

The present invention consists of a hot water tank, a nozzle device that sprays cleansing water to local areas, a valve unit that controls the amount of water supplied to the hot water tank and adjusts the water force from the nozzle device, and a rotary valve that rotates the needle valve of the valve unit. In a sanitary washing device in which a drive shaft is provided in a casing and a knob for adjusting water pressure arranged on the surface of the casing is connected to the rotation drive shaft, a stopper rib that engages with a protrusion provided on the circumferential surface of the rotation drive shaft on the inner surface of the casing. The stopper rib restricts the rotation of the rotary drive shaft to prevent the needle valve from locking.

〔Example〕

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

FIG. 1 is a perspective view of a flush toilet equipped with a sanitary cleaning device A according to the present invention, where B is the toilet bowl body, C is a flush water tank for cleaning the toilet bowl, and D and E are a toilet seat and a toilet lid.

Fig. 2 is an internal plan view of the sanitary washing device A, in which 1 is a mounting board fixed to the rear of the toilet body B, an operating part casing 2 is integrally connected to the left side, a side casing 3 is at the bottom, and an upper part is at the top. Casing 4
are connected to form the main body of the sanitary cleaning device A.

5 is a hot water tank disposed inside the side casing 3 and heats and stores cleaning water; 6 is a valve unit that communicates with an external water supply source through a connecting pipe 7 and has a supply pipe 8 between it and the hot water tank 5; 1 is a nozzle device having a nozzle body 11 that can move forward and backward and communicates with a cleaning water supply pipe 10 connected to the outlet of the hot water tank 4 and spouts cleaning water, and 12 is a hot air fan that performs drying after cleaning.

The inside of the valve unit 6 is equipped with a needle valve N for supplying/stopping the cleaning water and adjusting the flow rate.

Reference numeral 16 designates a bendable rotary drive shaft disposed between this knob 15 and the needle valve operating portion of the valve unit 6. As shown in FIG. 3, a knob attachment portion 17 is provided at one end, and a steel wire A flexible shaft 18 is connected to the flexible shaft 18 in the form of a coil spring by winding the same diameter, and a sleeve 19 which is made freely bendable by winding a steel wire in the same manner is inserted around the flexible shaft 18.

The knob attachment part 17 has a knob engagement part 20 on the tip side.
An engagement groove 21 is recessed in the peripheral surface of the shaft portion 22, and a flange 23 and a projection 24 are formed on the shaft portion 22, respectively.

The operation part casing 2 is provided with a cylindrical part 26 formed with a female screw 25, and a bottom part 28 is formed at the lower end of the cylindrical part 26 with a hole 27 through which the shaft part 22 of the knob mounting part 17 is inserted. Further, a stopper rib 29 extending from the hole 27 is provided on the outside of the bottom portion 28, and can engage with the protrusion 24 of the shaft portion 22 to restrict rotation when the rotary drive shaft 16 rotates.

Further, 30 is a bearing screwed and fixed to the cylindrical portion 26,
Insert the flange 23 into contact with the bottom 28 of the cylindrical portion 26, and then fit the knob 15 into the engagement portion 20 at the tip, and fit the protrusion 31 provided on the inner periphery into the engagement groove 21 for connection. ing.

A cleaning water flow path 32 is formed in the valve unit 6, and a valve body 33 of a needle valve N is fitted so as to be movable toward the flow path 32. The tip of the rotary drive shaft 16 is inserted into the hollow part 34 of the valve body 33, and rotational torque is transmitted by the key 35.
By moving the valve body 33 back and forth, the flow area of the wash water flow path 32 is changed to adjust the force of the wash water.

Here, when the knob 15 is rotated, the rotary drive shaft 16 is also rotated, and the valve body 33 of the needle valve N is operated as described above, so that the force of the washing water can be adjusted.

At this time, as shown in FIG.
The protrusion 24 provided on the shaft portion 22 of the stopper rib 29
This engagement restricts the rotation of the rotary drive shaft 16, and even if the knob 15 is accidentally turned too much, this engagement can prevent the rotary drive shaft 16 from over-rotating.

Therefore, the forward and backward stroke of the valve body 33 of the valve unit 6 is always constant, and the valve body 33 of the valve unit 6 can always operate smoothly without being locked.

[Effect of idea]

The present invention has the effect of preventing over-rotation of the rotary drive shaft for water force adjustment, thereby preventing the needle valve of the valve unit from locking, and ensuring the water force adjustment of the washing water.
