Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a sanitary cleaning device for cleaning private parts of the human body with warm water.

2. Description of the Related Art Conventionally, this type of sanitary cleaning device was developed, for example, in
As shown in Publication No. 84, the waterway configuration was as shown in Figure 3.

That is, the water supply source 6o is equipped with an on-off valve 612, a distribution section 52, a flow control valve 63. Hot water tank 54. Intake valve 66° Vacuum break valve 66
, a spouting section 67 is connected to the value column to constitute a main water channel, and a sub channel consisting of a vacuum breaker valve 68 and a drain port 59 is connected from the distribution section 52. In this configuration, when the user opens the on-off valve 61, water flows into the main waterway from the water supply source 60, is heated in the hot water tank 64, becomes hot water, and is ejected from the spouting part 67, which is a cleaning nozzle, to the user. Used for local cleansing. The cleaning flow rate can be adjusted by the user himself/herself by rotating the knob of the flow rate control valve 63, such as a needle valve, to narrow the water channel.

The sub-channel is designed to meet the minimum water discharge rate of 60 t/hour specified by the Japan Water Works Association when the device is in use, and the on-off valve 61
When the toilet is opened, a small amount of water is discharged into the toilet bowl.

Problems to be Solved by the Invention However, in such a configuration, when the water supply source is a tap water supply, the cleaning water force changes due to fluctuations in tap water pressure. This type of sanitary cleaning device is often used in the morning, but tap water is also often used in the kitchen or washroom at the same time, and it is inevitable that the tap water pressure will fluctuate during cleaning. Even if the user washes with the desired water pressure, if the water pressure of the water source increases, the water pressure will increase and the area to be cleaned may become painful, or if the water pressure of the water source decreases, the water pressure will increase. As a result, the cleaning ability deteriorates and the user feels unsatisfied, and the user has to adjust the flow rate control valve 53 every time the water pressure fluctuates, making it inconvenient to use.

Moreover, if the spouting part 67 was clogged with water scale, dirt, etc., the water pressure in the main waterway would increase, and there was a risk that the hot water tank 54 and the like would be damaged.

Therefore, the present invention eliminates the need for the user to adjust the water pressure each time the tap water pressure fluctuates, and automatically corrects the water pressure to the desired water pressure. To provide a sanitary cleaning device that does not apply high water pressure to waterways.

Means for Solving the Problems The means of the present invention for solving the above-mentioned problems is to provide a flow rate adjustment means and a pressure detection means for detecting the pressure on the secondary side of the flow rate adjustment means. A control device is provided for controlling the flow rate adjusting means so that the detected value becomes equal to the set value of the pressure setting means to which the user has set the desired water force.

For production The effect of this technical means is as follows.

In other words, even if the water pressure of the water supply means fluctuates, the flow rate adjustment means automatically adjusts so that the detected value of the pressure detection means and the set value of the pressure setting means, in which the user has set the desired water force, are always equal. Therefore, the pressure on the secondary side of the flow rate adjusting means is constant, and cleaning can be performed with a constant water force, so that the user does not need to adjust the water force every time the water pressure fluctuates.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

FIG. 2 is an external view of the sanitary washing device of the present invention, in which the device main body 2 is placed on the toilet bowl 1, and the toilet seat 3 and toilet lid 4 that are rotatably attached to the device main body 2 are placed. There is. 6 is a low tank for cleaning the toilet bowl 1, and is supplied with water through a water supply pipe 6 directly connected to the water supply. In the middle of this water supply pipe 6,
The branch faucet 7 is connected to the outlet of the branch faucet 7,
Water is supplied to the device main body 2 by connecting the water supply port 8 of the device main body 2 with a connecting pipe 9. Reference numeral 1o denotes a cleaning nozzle, which is extended when the user performs a cleaning operation using operating means 11 provided on the upper surface of the left sleeve of the main body 2 of the apparatus, and hot water is ejected to clean the private parts of the human body. Reference numeral 12 denotes an adjustment box housing pressure setting means for setting the water force desired by the user.

FIG. 1 is a configuration diagram of a cleaning device built into the main body 2 of the device. A solenoid valve 13 serving as a water supply means is connected to the water supply port 8, and is opened by a user's cleaning operation to supply water into the apparatus main body 2. The motor 1 is connected to the secondary side of the solenoid valve 13.
Flow control valve 1 whose throttle amount is adjusted by the rotation of 4.
5. A hot water tank 17 for heating and storing water by a heater 16 and a cleaning nozzle 10 are connected in series to form a cleaning channel. A pressure detection means 18 for detecting the pressure in the cleaning channel is attached to the secondary side of the flow rate control valve 15, and the detected value of the pressure detection means 18 and the pressure setting set by the user to set the desired water force are attached. The set value of the means 19 is compared by the control device 2o, and the motor 14 is controlled by the control device 20 so that the flow control valve is automatically adjusted so that the detected value is equal to the set value.

Further, a certain high pressure level is set in the control device 20, and when the detected value of the pressure detection means 18 exceeds the high pressure level, the control device 20 stops energizing the solenoid valve 13, and The valve 13 is closed to cut off the waterway.

Next, the operation of the configuration of this embodiment will be explained.

When the user sits on the toilet seat 3 and performs a cleaning operation using the operating means 11, the control device 2o opens the solenoid valve 13, and the branch faucet 7. Water is supplied to the secondary side of the solenoid valve 13 through the connecting pipe 9. At the same time, the control device 2o controls the motor 1.
4 is supplied with power, the flow control valve 16 is gradually opened from the closed state, and water flows into the hot water tank 17. At this time, the pressure on the secondary side of the flow rate control valve 16 is
8 and sends a signal to the control device 2o.

In the control device 20, the detected value of this pressure detection means 18,
The user compares the set value of the pressure setting means 19 to which the user has set the desired water force, supplies power to the motor 14, opens the flow control valve 16, and compares the detected value and the set value until the detected value becomes equal to the set value. When the values become equal, the energization to the motor 14 is stopped and the degree of opening of the valve portion of the flow control valve 16 becomes stable. The water flowing into the hot water tank 17 pushes out the hot water stored in the hot water tank 17, causes the cleaning nozzle 10 to extend, and hot water is sprayed toward the private parts of the human body. The force of the jetted hot water is
This is the nitrogen water force set by the user in the pressure setting means 19, and the user can always wash with the optimum water force.

If the water pressure of the water source increases during cleaning, the detected value of the pressure detection means 18 will be higher than the set value of the pressure setting means 19, so the control device 20 will immediately apply feedback to reverse the motor 14, The flow control valve 16 is closed until the detected value becomes equal to the set value, and when the value becomes equal, the flow becomes stable. When the water pressure of the water supply source decreases, the detected value of the pressure detection means 18 becomes lower than the set value of the pressure setting means 19, so in this case as well, shift feedback is applied to the control device 20, causing the motor 14 to rotate forward. The adjustment control valve 16 is opened, and when the detected value becomes equal to the set value, it stops and stabilizes.

Additionally, if the jet nozzle of the cleaning nozzle 1o becomes narrow due to being clogged with dust or water scale, the jet from the cleaning nozzle 1o will become narrower and the jetting speed will increase, and the water force per unit area in the cleaning private area will become stronger. However, in this case as well, the detected value of the pressure detection means 18 becomes high, and the flow control valve 15 is closed due to the above-mentioned action, and the water force is adjusted to the user's preference. It doesn't make you feel any pain.

When the jet nozzle of the cleaning nozzle 1o is completely blocked, the flow control valve 15 is closed and high pressure is not applied to the hot water tank 17 etc., thereby preventing water leakage or damage.

As described above, according to the present embodiment, even if the water pressure of the water supply source fluctuates during washing, the flow rate control valve 16 is automatically controlled so that the water force is always the same as that set by the user in the pressure setting means 19. This eliminates the need for the user to operate the flow control valve each time the water pressure fluctuates, making it extremely easy to use.

Furthermore, even if the jet nozzle of the cleaning nozzle 10 becomes narrow due to water scale, dirt, etc., the water force becomes strong and the user does not feel any pain, so that safe and always optimal cleaning can be performed.

Even if the spout of the cleaning nozzle 10 is still completely blocked,
The flow rate control valve 16 automatically closes to prevent water leakage or damage to the hot water tank or the like due to high pressure.

Further, in this embodiment, a certain high pressure level is set in the control device 2o, and when the detected value of the pressure detection means 18 exceeds the high pressure level, the solenoid valve 13 closes and blocks the waterway. , even if the water supply suddenly becomes abnormally high pressure,
This prevents abnormally high water pressure from harming the user, and prevents water leakage and damage from the cleaning channel.

A method using a flow rate sensor as a feedback method for the cleaning water force is also considered, but since this method controls the cleaning flow rate to always be constant, if the cleaning nozzle spout becomes narrow due to water scale etc., the jet speed may decrease. When the pressure increases, the user feels pain, and when the spout is completely blocked, the flow control valve opens fully, causing water leakage or damage due to the high pressure in the water channel. The pressure feedback system of this embodiment also solves the above problems, and can be said to be a safer and superior system than the flow rate sensing system.

Effects of the Invention The present invention includes a flow rate adjustment means and a pressure detection means for detecting the pressure on the secondary side of the flow rate adjustment means, and the detection value of the pressure detection means and the pressure setting means in which the user sets the desired water force. A control device is installed to control the flow rate adjustment means so that the set values are equal, so even if the water pressure of the water supply source fluctuates during cleaning,
The user can always wash with the water force of their choice, making it very easy to use.

In addition, even if the cleaning nozzle's spout becomes thin due to water stains or dirt, the spouting speed will not increase, so the user will not feel any pain, and cleaning can be performed safely. Wear.

As described above, according to the present invention, it is possible to provide a sanitary cleaning device that is extremely easy to operate, safe, and can be used in a consistent manner.
