Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a sanitary cleaning device that is attached to a toilet or the like to clean the private parts of the human body.

[Prior Art] As shown in FIG. 1, a conventional device of this type includes a cylinder 1 that introduces cleaning water into the interior from its base 3, and a spring 4 that moves inside the cylinder 1 in response to the introduced cleaning water pressure. A cleaning nozzle 2 that slides against an urging force, a flange 5 formed at the base end of the cleaning nozzle 2 and in sliding contact with the inner wall of the cylinder 1, and a flange 5 formed inside the cylinder 1 that when the cleaning nozzle 2 protrudes to a predetermined position, Step portion 6 that locks the flange 5
There is known a type of device that is equipped with a cleaning nozzle and discharges cleaning water to clean the private parts of the human body.

Here, a small gap is provided between the flange 5 and the inner wall of the cylinder 1 in order to reduce the frictional resistance that occurs when the cleaning nozzle 2 advances and retreats, and when the cleaning nozzle 2 protrudes to the cleaning position, the flange 5
comes into contact with the stepped portion 6 and the gap is sealed, and all of the cleaning water introduced into the cylinder 1 flows through the cleaning nozzle 2.
The water is discharged from the water outlet 7.

[Problems to be solved by the invention] By the way, the pressure of the cleaning water discharged from the cleaning nozzle 2 is determined by the water pressure introduced into the cylinder 1, and this water pressure is at least affected by the biasing of the spring 4. It must be possible to push out the cleaning nozzle against the force. Also spring 4
Since the cleaning water must have sufficient urging force to return the cleaning nozzle 2 to its normal state after cleaning, the cleaning water cannot project the cleaning nozzle 2 to the cleaning position unless there is a certain level of water pressure. That is, washing water must always be sprayed at a high pressure above a certain level, and washing cannot be performed with weak water pressure. Therefore, washing with low water pressure without irritation can be painful for people with hemorrhoids.

[Means for solving the problem] This invention provides a recess in the contact part of the stepped part of the cylinder with the flange, and when the cleaning nozzle protrudes to a predetermined position and the flange is locked to the stepped part, the cylinder is removed. forming a flow path through which a part of the washing water introduced into the toilet bowl is discharged to the toilet side without being released from the washing nozzle, and is bent in response to water pressure higher than the water pressure required to project the washing nozzle to the predetermined position; The above problem is solved by providing the flange with a soft member that tightly contacts the recess and closes the flow path.

[Example] Hereinafter, the example will be described based on the example shown in FIG. 2 and subsequent figures.

FIG. 2 is an explanatory diagram showing the configuration of a sanitary cleaning device embodying the present invention, in which 11 is a toilet bowl, 12 is a toilet seat, and 13 is a toilet bowl.
1 is a low tank for a faucet, and 14 is a cleaning device main body. 15 is the filter 1 from the low tank 13
6. A pump that sucks water through a hose 17; 18 is a hot water tank that communicates with the pump 15 through a hose 19, and is equipped with a heater inside to heat the stored water to a constant temperature; 20 is the hot water tank 18
A nozzle device that communicates with the low tank 1 through a hose 21 and a solenoid valve 22,
3 and discharges the cleaning water heated in the hot water tank 18. Reference numeral 23 denotes an operating section, which is equipped with a cleaning switch for driving the pump 5, an adjustment knob for adjusting the water pressure discharged from the pump, and the like.

3 and 4 are cross-sectional explanatory views of an embodiment of the nozzle device 20. FIG. A cylinder 24 forms a water supply port 25 connected to the hose 21 and introduces cleaning water into the cylinder. Reference numeral 26 denotes a cleaning nozzle that slides inside the cylinder 24, and is formed into a hollow tube shape and sprays cleaning water introduced into the cylinder 24 from a water discharge port 33 at the tip.The water pressure of this cleaning water causes the spring 27 to be attached. It operates so that it is pushed out of the cylinder 24 by a predetermined amount against the force. A flange 28 is formed at the base of the cleaning nozzle 26 and is in sliding contact with the inner wall of the cylinder 24. The flange 28 has a small distance from the cylinder 24, and a portion of the cleaning water introduced into the cylinder 24 is transferred to the nozzle 26. It leaks to the outer periphery. This leaked cleaning water is sent to the nozzle 26 at the tip of the cylinder 24.
It is discharged into the toilet bowl 11 through the gap formed at the sliding contact portion with the toilet bowl 11.

The outer edge of the flange 28 is made of a soft material such as an elastomer, and a portion 29 thereof is formed thin. Inside the cylinder 24 is a step 30.
is formed and the cleaning nozzle 26 protrudes by a predetermined distance (see FIG. 4) and comes into contact with the flange 28, where the flange 28 functions as a sealant. As shown in detail in FIG. 5, this stepped portion 30 has a relatively shallow recess 31 formed at a position corresponding to the thin wall portion 29 of the flange 28. When abutted, the flange 28 normally formed by this recess 31
A part of the cleaning water leaks from the tip of the cylinder, and when the cleaning water pressure increases, the thin part 29 bends and comes into close contact with the recess 31, blocking the leakage passage. It is configured.

Therefore, the cleaning water introduced into the cylinder 24 is discharged from the water outlet 33 while pushing out the nozzle 26 with its water pressure, and a part of it is discharged from the cylinder 24.
The water is discharged from the tip of the cylinder 24 into the toilet bowl 11 through the sliding contact between the cylinder 24 and the nozzle 26. When the water pressure of the cleaning water introduced into the cylinder 24 is relatively low, even if the nozzle 26 protrudes to a predetermined position and contacts the stepped portion 30 of the cylinder 24, a portion of the cleaning water is washed through the recess 31. The water is discharged without reaching the inside of the nozzle 26, and the force of water discharged from the water outlet 33 is reduced by this amount.

On the other hand, when the cleaning water is under high pressure, the thin wall portion 29 of the flange 28 comes into close contact with the recess 31 due to the water pressure, and all of the cleaning water flows through the cleaning nozzle 26.
Water is discharged from the water discharge port 33, and water can be discharged at a sufficiently high pressure.

[Effects of the invention] This invention is constructed as described above, and a portion of the washing water is discharged toward the toilet bowl with the washing nozzle protruding to a predetermined position. While applying water pressure inside the cylinder, it is possible to wash with a weaker water force, making use particularly comfortable for people with hemorrhoids who are particularly sensitive.

In addition, when the water pressure increases, the flange bends and stops draining into the toilet bowl, and all of the washing water is released from the washing nozzle, making it possible to wash with a high flow of water without any loss compared to conventional methods. The adjustment range can be expanded from low water pressure to high water pressure.
