A diverter valve for a smart toilet and its control method

Abstract

A water diverter valve for an intelligent toilet and a control method thereof. Two self-cleaning ports are designed on a static plate of the water diverter valve. The two self-cleaning ports are connected through a flow channel on the back of the static plate, thereby avoiding the need to pass through a buttocks / female wash area when using a defecation-assisting function, and avoiding the disadvantage that water will bubble out of the buttocks / female wash area when using the defecation-assisting function. When a movable plate rotates to switch between a buttocks / female wash water outlet area and a defecation-assisting / wall-moistening water outlet area, one of the self-cleaning ports can discharge cold water, thereby achieving no cold water transition in the defecation-assisting / wall-moistening water outlet area. The notch of the movable plate will stay at the first self-cleaning port in the product standby state. When the defecation-assisting function is used, the water diverter valve does not enter water, and the movable plate first rotates from the first self-cleaning port to the second self-cleaning port. At this time, the second self-cleaning port discharges residual water between the electromagnetic valve, the heater, the water diverter valve, and the spray rod, thereby avoiding residual water from spraying out and causing discomfort to the human body. The buttocks / female wash flow channel and the defecation-assisting / wall-moistening water outlet area flow channel on the static plate are arc-shaped with gradually changing widths, thereby facilitating the adjustment of the water flow rate of the defecation-assisting / wall-moistening water outlet area flow channel.

Description

Technical Field

[0001] The invention relates to a water diverter valve, in particular to a water diverter valve for an intelligent toilet and a control method thereof. Background Art

[0002] On January 12, 2021, the applicant submitted an application number of 2021200808150 to the State Intellectual Property Office for a smart toilet water diverter valve. The applicant upgraded and optimized the design based on this technical solution, so that when the buttocks / female wash water outlet area and the defecation / wall moisturizing water outlet area are switched in the water diverter valve, there can be no cold water transition in the defecation / wall moisturizing water outlet area. In the new design, two self-cleaning ports are designed on the static plate, and the two self-cleaning ports are connected through the flow channel on the back of the static plate, avoiding the need to pass through the buttocks / female wash area when using the defecation-assisting function, and avoiding the disadvantage of water bubbling out of the buttocks / female wash area when using the defecation-assisting function.

[0003] See also Fig.11 In the original scheme of the applicant, there is only one self-cleaning opening 14 on the static piece, and the women's washing area 13 on the static piece is adjacent to the defecation-assisting area 15. If the user uses the defecation-assisting function, the gap of the moving piece first rotates to the women's washing area 13 and then passes through the defecation-assisting area 15. When passing through the women's washing area 13, as the water diverter valve increases in the number of uses, there is residual water between the solenoid valve, the heater, the water diverter valve, and the spray rod. Therefore, during the process of switching the women's washing area 13 to the defecation-assisting area 15, the spray rod will spray water onto the human body. If the water is cold water, the human body will feel uncomfortable. Especially when the product is in standby mode, after the machine is turned on, when the user uses the defecation-assisting function of the smart toilet water diverter valve, after the solenoid valve is opened, the gap of the moving piece passes through the women's washing area 13 and the defecation-assisting area 15. Since part of the residual water is outside the heater, part of the residual water cannot be heated by the heater. This water is cold water, so this cold water is sprayed from the women's washing area 13 through the defecation-assisting area 15 to the human body along with the gap of the moving piece, making the human body feel uncomfortable. Therefore, further improvement is made. Summary of the invention

[0004] The purpose of the present invention is to provide a water diverter valve for an intelligent toilet and a control method thereof, which can achieve no cold water transition in the defecation-assisting / wall-moistening water outlet area when the buttocks-changing / female-washing water outlet area and the defecation-assisting / wall-moistening water outlet area are switched in the water diverter valve, so as to overcome the shortcomings of the prior art.

[0006] Two self-cleaning ports are designed on the static piece, and the two self-cleaning ports are connected through the flow channel on the back of the static piece, avoiding the need to pass through the buttocks / female wash area when using the defecation aid function, and avoiding the disadvantage of water bubbling up from the buttocks / female wash area when using the defecation aid function (especially when the defecation aid function is used directly when the product is in standby mode).

[0007] The static piece is provided with two interconnected self-cleaning ports. When the dynamic piece rotates to switch the buttocks / female wash water outlet area and the defecation / wall moistening water outlet area, one of the self-cleaning ports can discharge cold water, so that there is no cold water transition in the defecation / wall moistening water outlet area.

[0008] When the user finishes cleaning on the smart toilet, the notch of the moving piece will stay at the first self-cleaning port, the first buttocks / female wash flow channel is the female wash water outlet area, and the second buttocks / female wash flow channel is the buttocks wash water outlet area. When the female wash water outlet area switches to the defecation-aiding / wall-smoothing water outlet area, the water diverter valve does not let water in at this time, and the moving piece first rotates from the first self-cleaning port to the second self-cleaning port. At this time, the second self-cleaning port first discharges the residual water between the solenoid valve, heater, water diverter valve, and spray rod to prevent the residual water from splashing onto the human body and making the human body feel uncomfortable.

[0009] The first self-cleaning port and the second self-cleaning port are arranged on one end face of the static plate at left and right intervals, and a self-cleaning port flow channel is arranged on the other end face of the static plate.

The water flow in the flow channel of the toilet / wall water outlet area is regulated by the static piece bonding surface blocking the size of the flow channel area of ​​the toilet / wall water outlet area to control the water flow; similarly, the size of the buttocks / women's wash flow channel area is blocked by the static piece bonding surface to control the water flow. The gap and the static piece bonding surface rotate with the moving piece, and the static piece bonding surface will block part of the flow channel of the static piece. At this time, if other flow channels are connected to the gap, water will flow out of the water diversion valve through the flow channel and the gap.

[0013] The water diverter valve for a smart toilet also includes a water outlet seat assembled with a static plate, and the water outlet seat is provided with a buttocks / female wash water outlet pipe and a defecation / wall moistening water outlet pipe corresponding to the buttocks / female wash water outlet area and the defecation / wall moistening water outlet area respectively, and an independent self-cleaning outlet water outlet pipe is provided on the water outlet seat corresponding to the first self-cleaning outlet and the second self-cleaning outlet.

[0014] A sealing ring is arranged between the static piece and the water outlet seat, and a sealing groove for installing the sealing ring is arranged on the static piece. The sealing ring plays a role in preventing water leakage from the water outlet seat.

[0015] The water diverter valve for a smart toilet also includes a valve body covering a transmission shaft, a moving plate, and a stationary plate, one end face of the valve body and a water outlet seat are tightly assembled by fasteners, the water diverter valve also includes a water diverter valve motor, the water diverter valve motor and the other end face of the valve body are tightly assembled by fasteners, and the water diverter valve motor shaft of the water diverter valve motor is drivingly connected to the transmission shaft;

[0016] A first limiting protrusion is provided in the inner cavity of the valve body, and a second limiting protrusion is provided on the transmission shaft corresponding to the first limiting protrusion. The first limiting protrusion and the second limiting protrusion contact during the rotation of the transmission shaft to form a water diversion valve motor driving the moving plate notch to rotate to the initial position of the first self-cleaning port through the transmission shaft.

[0017] The first water inlet end of the water diverter valve is connected to a heater through a pipeline, the heater is connected to a solenoid valve through a pipeline, the solenoid valve is connected to a water source through a pipeline, the outlet pipe of the water diverter valve is connected to a spray rod through a pipeline, the spray rod is provided with a plurality of second water inlet ends, each hip / women's wash outlet pipe, self-cleaning outlet pipe, and defecation / wall moistening outlet pipe are respectively connected to the corresponding second water inlet end through a pipeline, the spray rod comprises a rod body, and a women's wash water spray port, a hip wash water spray port, a defecation / wall moistening water spray port are provided on the surface of the rod body, the women's wash water spray port, the hip wash water spray port, the defecation / wall moistening water spray port The water spray outlet is connected with the corresponding buttocks / women's wash water outlet pipe through a pipe, the defecation / wall moistening water spray outlet is connected with the defecation / wall moistening water outlet area water outlet pipe through a pipe, a self-cleaning water outlet seat is provided on the top of the rod body, and a self-cleaning water sprinkling hole is provided on the surface of the rod body corresponding to the self-cleaning water outlet seat, the water inlet level of the self-cleaning water outlet seat is connected with the self-cleaning water outlet pipe through a pipe, a cleaning flow channel is provided between the self-cleaning water outlet seat and the surface of the rod body, and the water flowing out of the self-cleaning water sprinkling hole flows to the women's wash water spray outlet, the buttocks wash water spray outlet, and the defecation / wall moistening water spray outlet through the cleaning flow channel.

[0018] When the notch of the moving piece rotates to one of the self-cleaning ports of the static piece, water will flow out of the water sprinkling hole of the self-cleaning port, and the water will flow through the cleaning flow channel to the women's wash water spray port, the buttocks wash water spray port, and the defecation / wall moistening water spray port to clean the women's wash water spray port, the buttocks wash water spray port, and the defecation / wall moistening water spray port.

[0019] The surface of the rod body is arc-shaped, which is convenient for guiding the water flow of the cleaning flow channel to the women's wash water spray outlet, the buttocks wash water spray outlet, and the defecation-aiding / wall-moistening water spray outlet.

[0020] A control method for a water diverter valve for an intelligent toilet designed for this purpose includes the water diverter valve for an intelligent toilet, and also includes a main control board for controlling the operation of a water diverter valve motor. The main control board is provided with a control program. The water diverter valve motor, the heater, and the solenoid valve are electrically connected to the main control board respectively. In the power-on state, the water diverter valve motor shaft of the water diverter valve motor rotates through the transmission shaft. When the second limit protrusion of the transmission shaft contacts the first limit protrusion of the valve body cavity, the transmission shaft does not move. The information is fed back to the control program of the main control board for controlling the operation of the water diverter valve motor. The control program of the main control board calculates the number of times the water diverter valve motor needs to operate from the position of the moving piece gap to the first self-cleaning port. The water diverter valve motor then drives the transmission shaft to rotate, so that the gap of the moving piece stays at the first self-cleaning port each time the product is in the standby state.

[0021] Each time the smart toilet is powered on, the water diverter valve and the spray rod enter an initialization operation program, which causes the notch of the water diverter valve moving piece to stay at the first self-cleaning opening, and the rod body of the spray rod to stay at the fully retracted position;

[0022] A. If the user uses the buttocks washing function and opens the solenoid valve, if there is residual water in the water path between the solenoid valve, heater, water diverter valve and spray rod, when the water diverter valve is opened to let in water, the residual water will be discharged through the first self-cleaning port of the water diverter valve and the outlet of the self-cleaning port of the spray rod in turn, and the residual water will flow from the cleaning flow channel to the spray rod and clean its rod body and water spray port. When the water temperature reaches 35℃ (Note: the national standard for smart toilets requires that the water temperature when in contact with the human body should not be lower than 35℃), the water diverter valve will control the water diverter valve motor to run through the control program of the main control board, and the water diverter valve motor will drive the notch of the moving piece to rotate to the first buttocks / female washing flow channel or the second buttocks / Female wash flow channel (Note: rotate according to the selected cleaning outlet, at this time the rod body is in a fully retracted state), discharge the cold water in the pipe between the water diverter valve and the spray rod and then return to the second self-cleaning outlet, and then control the water diverter valve motor of the spray rod through the control program of the main control board to make the rod body extend to the designated position of buttocks / female wash (Note: each time the spray rod and the water diverter valve are powered on, there is also a reset program to reset to the designated position), the water diverter valve is then controlled by the control program of the main control board. The water diverter valve motor is operated, and the water diverter valve motor drives the notch of the moving piece to rotate to the first buttocks / female wash flow channel or the second buttocks / female wash flow channel, and then flows to the female wash water spray outlet or buttocks wash water spray outlet of the spray rod to spray onto the human body; (Note: A is to achieve the function of discharging residual water and cold water)

[0023] B. If the user uses the defecation-assisting function, the water diverter valve controls the water diverter valve motor to operate through the control program of the main control board. The water diverter valve motor drives the notch of the moving piece to rotate to the second self-cleaning port and then opens the solenoid valve. If there is residual water in the water path between the solenoid valve, heater, water diverter valve and spray rod, when the water diverter valve is opened to inlet water, the residual water is discharged through the second self-cleaning port of the water diverter valve and the outlet of the self-cleaning port water outlet seat of the spray rod in turn. The residual water flows from the cleaning flow channel to the spray rod and cleans its rod body and water spray port. When the water temperature reaches 35°C, the water diverter valve controls the water diverter valve motor through the control program of the main control board. The machine is running, and the water diverter valve motor drives the notch of the moving piece to rotate to the flow channel of the defecation-aiding / wall-moistening water outlet area (Note: rotate according to the selected cleaning outlet, and the rod body is in a fully retracted state at this time), and the cold water in the pipe between the water diverter valve and the spray rod is discharged and then returns to the second self-cleaning outlet, and then the water diverter valve motor of the spray rod is controlled by the control program of the main control board to make the rod body extend to the designated position of the defecation-aiding, and the water diverter valve motor is controlled by the control program of the main control board to operate, and the water diverter valve motor drives the notch of the moving piece to rotate to the flow channel of the defecation-aiding / wall-moistening water outlet area, and then flows to the defecation-aiding / wall-moistening water outlet of the spray rod and sprays onto the human body.

[0024] The beneficial effects of the present invention are as follows:

[0025] The static piece is provided with two interconnected self-cleaning ports. When the dynamic piece rotates to switch the buttocks / female wash water outlet area and the defecation / wall moistening water outlet area, one of the self-cleaning ports can discharge cold water, so that there is no cold water transition in the defecation / wall moistening water outlet area.

[0026] Two self-cleaning ports are designed on the static piece, and the two self-cleaning ports are connected through the flow channel on the back of the static piece, avoiding the need to pass through the buttocks / feminine wash area when using the defecation assistance function, and avoiding the disadvantage of water bubbling up from the buttocks / feminine wash area when using the defecation assistance function.

[0027] When the user finishes cleaning on the smart toilet, the notch of the moving piece will stay at the first self-cleaning port, the first buttocks / female wash flow channel is the female wash water outlet area, and the second buttocks / female wash flow channel is the buttocks wash water outlet area. When the female wash water outlet area switches to the defecation-aiding / wall-smoothing water outlet area, the water diverter valve does not let water in at this time, and the moving piece first rotates from the first self-cleaning port to the second self-cleaning port. At this time, the second self-cleaning port first discharges the residual water between the solenoid valve, heater, water diverter valve, and spray rod to prevent the residual water from splashing onto the human body and making the human body feel uncomfortable.

[0028] The moving piece is provided with a gap and a static piece for adjusting the water flow of each buttocks / women's wash flow channel, the flow channel of the toilet / wall water outlet area, and coordinating the switching of the buttocks / women's wash water outlet area and the toilet / wall water outlet area. The flow channel of the toilet / wall water outlet area is crescent-shaped. The water flow in the flow channel of the toilet / wall water outlet area is regulated by the static piece bonding surface blocking the size of the flow channel area of ​​the toilet / wall water outlet area to control the water flow; similarly, the size of the buttocks / women's wash flow channel area is blocked by the static piece bonding surface to control the water flow. The gap and the static piece bonding surface rotate with the moving piece, and the static piece bonding surface will block part of the flow channel of the static piece. At this time, if other flow channels are connected to the gap, water will flow out of the water diversion valve through the flow channel and the gap. BRIEF DESCRIPTION OF THE DRAWINGS
