Description

Technical Field

[0001] The present invention relates to the technical field of toilets, and in particular to a control method for a flushing water channel mechanism of a toilet. Background Art

[0002] As people's quality of life improves, toilets with cleaning functions have been widely used. Existing toilets generally introduce cleaning water through a water inlet valve switch, and the cleaning water is heated to a set temperature by an instant heater (instant electric water heater) and then sprayed to a local part of the human body by a spray rod for cleaning.

[0003] The traditional way to use a spray bar is to use it to clean the anus, which is good for health and can clean dirt between the folds that cannot be wiped off with toilet paper. It is now found that if the human body is continuously flushed with warm water through the spray bar, it can stimulate the surrounding capillaries, promote muscle relaxation and blood circulation, and prevent hemorrhoid diseases, constipation, etc. Especially for sedentary people, long periods of sitting still will cause the blood circulation around the anus to slow down. Using warm water to maintain a long time of flushing can accelerate the blood circulation in the anus and maintain good health.

[0004] However, existing toilets are usually heated by instant heaters. However, while instant heaters provide fast heating of water, they also have some disadvantages, mainly including:

[0005] First, household circuits are usually designed according to a certain power load to ensure that wires, meters, fuses and other equipment will not be damaged or cause fire due to overload. The use of instant heaters as high-power electrical appliances, if other household appliances are also used during its use, can easily exceed the capacity of household circuits, easily leading to safety accidents such as overheating of wires, damage to appliances and even fire.

[0006] Secondly, when the household water pressure or voltage fluctuates, or when the temperature control center of the instant heater itself is not accurate enough, it is easy for the water outlet temperature to fluctuate, reducing the user experience.

[0007] Third, when users use warm water for a long time, the instant heater maintains a high-power working state for a long time. Due to the large current ampere passing through, it is also easy to cause heating problems in the instant heater's own circuit, posing a safety hazard. Summary of the invention

[0008] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a control method for a flushing water channel mechanism of a toilet to solve the problems mentioned in the above background technology section.

[0014] The control method of the cleaning waterway mechanism comprises the following steps:

[0015] S1, when the controller receives a cold water outlet mode instruction from the user, it enters step S2; when the controller receives a warm water outlet mode instruction from the user, it enters step S3; when the controller receives an alternating water outlet mode instruction from the user, it enters step S4;

[0016] S2, the controller controls the second flow control valve to open, and supplies water to the spray rod through the second pipeline;

[0017] S3, the warm water outlet mode includes the following control steps:

[0018] S31, the controller controls the first flow control valve to open, and supplies water to the spray rod through the first pipeline;

[0019] S32, when the controller detects that the first flow control valve is in an open state and the height of the liquid level sensor read is lower than a first set height, the controller controls the fourth flow control valve and the heater to be turned on;

[0020] S33, when the controller detects that the first flow control valve is in an open state, and the temperature of the first temperature sensor read is lower than the second set temperature or the height of the liquid level sensor is lower than the second set height, the controller controls the third flow control valve and the instant heater to open;

[0021] S4. The controller realizes the alternating output of cold water and warm water by alternately controlling the output water flow of the first flow control valve and the second flow control valve.

[0022] The beneficial effects of the present invention are as follows: the water in the first chamber is heated by the heater and then stored, and the water in the first chamber is used in advance as output water when in use. Through the above control steps, warm water can be maintained for a long time. When the water temperature in the first chamber is low or the water volume is insufficient, the heater and the instant heater are used for heating and temperature adjustment. By maintaining warm water output under the premise of low power consumption, the burden on the circuit is small, and the safety hazards during operation are relatively reduced. The cleaning water circuit mechanism has three modes, and users can choose as needed to improve the comfort of the toilet and reduce the power of the cleaning water circuit mechanism when in use.

[0030] It also includes a first pipeline 3, a second pipeline 4, a third pipeline 5, and a mixed water pipeline 6 respectively connected to the first pipeline 3, the second pipeline 4 and the third pipeline 5, the other end of the first pipeline 3 is connected to the first chamber 12, the other end of the second pipeline 4 is connected to the second chamber 13, the other end of the third pipeline 5 is connected to the household water channel interface, and the second chamber 13 is provided with a second temperature sensor 131;

[0031] The water mixing pipeline 6 is provided with a spray bar 61, the first pipeline 3 is provided with a first flow control valve 31, the second pipeline 4 is provided with a second flow direction control valve 41, the third pipeline 5 is provided with a third flow control valve 51 and an instant heater 52, and the water inlet pipeline 2 is provided with a fourth flow control valve 21;

[0032] It also includes a controller, which is electrically connected to the first flow control valve 31, the second flow direction control valve 41, the third flow control valve 51, the fourth flow control valve 21, the instant heater 52, the heater 121, the liquid level sensor 123, the first temperature sensor 122 and the second temperature sensor 131 respectively.

[0033] When in use, water is supplied to the second chamber 13 through the water inlet pipe 2. When the second chamber 13 is full of water, the water flows over the partition 11 and enters the first chamber 12. The first chamber 12 is stored with warm water through the operation of the heater 121. Then, according to the input instruction of the user, the cleaning waterway mechanism of the present invention has three water outlet modes, namely cold water outlet, warm water outlet, and alternating cold water and warm water outlet. The user can choose as needed to improve the comfort of the toilet. In addition, the present invention heats the water in the first chamber 12 and stores it through the heater 121. When in use, the water in the first chamber 12 is used as the output water in advance. Through the above control steps, the warm water can be maintained for a long time. When the water temperature of the first chamber 12 is low or the water volume is insufficient, the heater 121 and the instant heater 52 are used for heating and temperature adjustment. By maintaining the warm water output under the premise of low power consumption, the circuit load is small, and the safety hazards during operation are relatively reduced. In addition, the cleaning waterway mechanism has three modes, and the user can choose as needed to improve the comfort of the toilet.

[0034] Among them, medicines for hemorrhoid diseases, perianal eczema, etc. can be placed in the first chamber 12, and then the warm water outlet mode of the present invention can be used to achieve a local medicinal bath effect on the human body, improve the treatment effect, and promote blood circulation.

[0035] Among them, the alternating water flow mode of cold water and warm water can promote blood circulation in the anal area to a certain extent by frequently switching between cold water and warm water to clean local parts of the human body, relieve the discomfort and fatigue caused by sitting for a long time, and give users a massage experience through alternating cold and hot water. And when users suffer from hemorrhoid diseases, anal eczema, etc., alternating cold and hot water can stimulate the skin and relieve pain.

[0036] The water storage tank 1 is provided with a pressure relief hole 14, in which a pressure relief valve is provided, and the pressure relief valve is electrically connected to the controller. When the water level sensor detects that the water level of the water storage tank 1 is too high, the controller controls the pressure relief valve to open. As another embodiment, a pressure bearing member is installed in the pressure relief hole 14, and the pressure bearing member replaces the pressure relief valve. When the water pressure is greater than the pressure bearing size of the pressure bearing member itself, the pressure bearing member cannot continue to bear the pressure and releases the pressure.

[0037] The third pipeline 5 is also provided with a switch valve 53 connected to the controller, that is, after the heater 52 completes heating the water flow in the third pipeline 5, the controller controls the switch valve 53 to open.

[0038] Reference Figure 2As shown, it also includes a cover plate 15 covering the first chamber 12, and a valve 16 connecting the partition 11 and the side wall of the water storage tank 1, the cover plate 15 extends downwardly in an inclined direction toward the valve 16, and the valve 16 is electrically connected to the controller. Thus, water flows over the partition 11, and the water flows along the cover plate 15 into the valve 16. The partition 11 and the cover plate 15 are heat-insulating structures. When water needs to be injected into the first chamber 12, the controller controls the valve 16 to open.

[0039] A booster pump 62 is provided in the mixed water pipeline 6. During the water discharge process, the third temperature sensor 63 detects that the water temperature meets the target temperature, that is, after the controller completes the temperature adjustment work, the booster pump 62 is started again to allow the water flow to impact the human body again, making the water flow more abundant, meeting the user's demand for water flow intensity. In addition, considering that the water flow that may remain in the spray rod 61 and is contaminated by the outside, the water flow is discharged during the temperature adjustment stage to ensure that the water flow used for the human body is clean water.

[0040] One-way valves are provided in the first pipeline 3 , the second pipeline 4 and the third pipeline 5 . By providing the one-way valves, water backflow can be prevented.

[0041] Reference Figure 3 As shown, specifically, the control method of the cleaning water channel mechanism includes the following steps:

[0042] S1, when the controller receives a cold water outlet mode instruction from the user, it enters step S2; when the controller receives a warm water outlet mode instruction from the user, it enters step S3; when the controller receives an alternating water outlet mode instruction from the user, it enters step S4;

[0043] S2, the controller controls the second flow control valve to open, and supplies water to the spray bar 61 through the second pipeline 4;

[0044] S3, the warm water outlet mode includes the following control steps:

[0045] S31, the controller controls the first flow control valve 31 to open, and supplies water to the spray bar 61 through the first pipeline 3;

[0046] S32, when the controller detects that the first flow control valve 31 is in an open state and the height of the liquid level sensor 123 read is lower than a first set height, the controller controls the fourth flow control valve 21 and the heater 121 to open;

[0047] S33, when the controller detects that the first flow control valve 31 is in an open state, and the temperature of the first temperature sensor 122 read is lower than the second set temperature or the height of the liquid level sensor 123 is lower than the second set height, the controller controls the third flow control valve 51 and the instant heater 52 to open;

[0048] S4. The controller realizes the alternating output of cold water and warm water by alternately controlling the output water flow of the first flow control valve 31 and the second flow control valve.

[0049] Through steps S31 to S33, the cleaning water channel mechanism can maintain outputting warm water with a constant temperature for a long time, and when the usage in the first chamber 12 is lower than the first set height, water replenishment and heating are performed simultaneously.

[0050] In step S32, when there is still a certain amount of water source in the first chamber 12, auxiliary heating is performed by the heater 121 to reduce the overall power consumption of the cleaning water channel mechanism.

[0051] In step S32, the spray bar 61 of the present invention can be selected to have a variety of water outlet flow rates, including a low flow setting of about 2-5 mL / s, a medium flow setting of about 5-10 mL / s, and a high flow setting of about 10-20 mL / s.

[0052] In step S33, when the water flow in the first chamber 12 is too low, the instant heater 52 performs auxiliary heating, so that the water flows of the first pipeline 3 and the third pipeline 5 enter the mixing water pipeline 6 and are mixed, and then sprayed out through the spray rod 61. The advantage is that the instant heater 52 does not need to operate at full load at this time, which can reduce the overall power consumption of the cleaning water channel mechanism.

[0053] Since the inlet water flows into the second chamber 13 and the third pipeline 5 respectively, the temperature detected by the second temperature sensor 131 is the water temperature of the third pipeline 5 or the water temperature of the second chamber 13 .

[0054] Furthermore, in step S32, the water flow rate m4 per unit time of the fourth flow control valve 21 is calculated by the following formula:

[0055]

[0056] Wherein: t is the unit time, P1 is the output power of the heater 121, c is the specific heat capacity of water, T2 is the identification temperature of the second temperature sensor 131, T X It is the target temperature input by the user or the target temperature preset by the controller.

[0057] By using the above formula, the relationship between the water consumption and the output power of the heater 121 is adjusted in real time, thereby ensuring a constant outlet water temperature.

[0058] In a further step S33, the water flow rate m3 per unit time of the third flow control valve 51 is calculated by the following formula:

[0059]

[0060] Wherein: t is the unit time, P2 is the output power of the instantaneous heater 52, c is the specific heat capacity of water, T1 is the identification temperature of the first temperature sensor 122, T2 is the identification temperature of the second temperature sensor 131, T X It is the target temperature input by the user or the target temperature preset by the controller.

[0061] By using the above formula, the relationship between the water consumption and the output power of the instant heater 52 is adjusted in real time, thereby ensuring the constant outlet water temperature.

[0062] The step S3 also includes step S34;

[0063] Step S34: When the liquid level sensor 123 detects that the water flow in the first chamber 12 is exhausted and the instant heater 52 stops working, the signal is transmitted to the controller, and the controller controls the first flow control valve 31 to close and the fourth flow control valve 21 to open until the water flow in the first chamber 12 returns to the set height, and then the controller controls the heater 121 to start. This avoids the heater 121 and the instant heater 52 working at the same time, causing an excessive load on the household circuit and a tripping.

[0064] Furthermore, in the step S32, the first set height is any value between 2 / 3H and H, wherein H is the highest height value that the chamber can accommodate.

[0065] Furthermore, in the step S33 , the second set height is any value between 0 and 1 / 3H, wherein H is the highest height value that the first chamber 12 can accommodate.

[0066] Furthermore, in step S33, the second set temperature is lower than the target temperature input by the user or the target temperature T preset by the controller. X When the temperature difference exceeds 3°, it is a temperature that can be clearly felt by the human body. At this time, the instant heater 52 is used to compensate the temperature, so that the outlet water temperature can be maintained, thereby improving the user experience.

[0067] Furthermore, the step S33 also includes step S331; step S331, when the controller detects that the temperature of the first temperature sensor 122 is equal to the temperature of the second sensor, the controller controls the first flow control valve 31 to close, so that the water flow is heated by the instant heater 52 and then flows out through the spray rod 61.

[0068] Furthermore, the step S31 includes the following steps:

[0069] S311, according to the target temperature input by the user or the target temperature preset by the controller, the controller obtains the target water temperature and determines whether the target water temperature is greater than the water temperature read by the first temperature sensor 122. When the target water temperature is less than the water temperature read by the first temperature sensor 122, the controller controls the first flow control valve 31 and the second flow control valve to start at the same time and adjust the water outlet temperature. At this time, the warm water in the first chamber 12 and the cold water in the second chamber 13 are supplied at the same time, reducing the mixed water outlet temperature so that the water outlet temperature is equal to the above target temperature.

[0070] Further, in step S311, the opening ratio of the water flow rate per unit time m1 of the first flow control valve 31 and the water flow rate per unit time m2 of the second flow control valve is calculated by the following formula:

[0071]

[0072] Where: T1 is the identification temperature of the first temperature sensor 122, T2 is the identification temperature of the second temperature sensor 131, T X It is the target temperature input by the user or the target temperature preset by the controller.
