Description

Technical Field

[0001] This utility model relates to the field of toilet technology, specifically to a toilet cleaning water circuit mechanism and a toilet. Background Technology

[0002] As people's quality of life improves, toilets with a washing function have become widely used. Current toilets typically introduce washing water through an inlet valve. This water is then heated to a set temperature by an instant water heater and sprayed onto specific areas of the body for cleaning.

[0003] Traditionally, a spray nozzle is used to clean the anus, which is beneficial to health and can remove dirt from the folds that toilet paper cannot reach. It has now been found that continuous warm water rinsing of the area with the nozzle can stimulate surrounding capillaries, promote muscle relaxation and blood circulation, and prevent hemorrhoids and constipation. This is especially beneficial for people who sit for long periods, as prolonged sitting slows blood circulation around the anus; sustained warm water rinsing can accelerate blood circulation in the anal area, maintaining overall health.

[0004] However, existing toilets typically use instant water heaters for heating, but while providing rapid hot water, instant water heaters also have some drawbacks, mainly including:

[0005] Firstly, household circuits are typically designed according to a certain power load to ensure that equipment such as wires, meters, and fuses will not be damaged or cause fires due to overload. Instant heaters, being high-power appliances, can easily exceed the capacity of the household circuit if other household appliances are also used during their operation, potentially leading to overheating of wires, damage to appliances, or even fires.

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

[0007] Thirdly, when users use warm water for a long time, the instant water heater maintains a high-power operating state for an extended period. Due to the large current passing through it, the instant water heater's own circuitry is prone to overheating, posing a safety hazard. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a water cleaning mechanism for a toilet and a toilet to solve the problems mentioned in the background section above.

[0009] This utility model is achieved through the following technical solution:

[0010] A flushing water system for a toilet includes a water tank with a partition dividing it into a first chamber and a second chamber. When the water level in the second chamber exceeds the partition, water flows from the second chamber into the first chamber. The water tank has an inlet pipe leading to the second chamber. The first chamber contains a heater, a first temperature sensor, and a level sensor. The system also includes a first pipe and a second pipe, as well as a mixing pipe connected to both pipes. The other end of the first pipe connects to the first chamber, and the other end of the second pipe connects to the second chamber. The mixing pipe has a spray bar. The first pipe has a first flow control valve, the second pipe has a second flow direction control valve, and the inlet pipe has a fourth flow control valve. The system also includes a controller electrically connected to the first flow control valve, the second flow direction control valve, the fourth flow control valve, the heater, the level sensor, and the first temperature sensor.

[0011] The beneficial effects of this utility model are as follows: the water in the first chamber is heated and stored by the heater, which reduces the burden on the circuit. Users can select the first chamber or the second chamber for water output as needed, realizing the free selection of cold water and warm water. The water temperature can be adjusted by simultaneously opening the first flow control valve and the second flow control valve. When the user selects the alternating cold water and warm water output mode, the first pipeline and the second pipeline pass through warm water and cold water respectively, without interfering with each other, avoiding affecting the water temperature, and reducing the power consumption of the cleaning water circuit mechanism.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Reference Figures 1 to 2 As shown, this utility model provides a water cleaning mechanism for a toilet. The water cleaning mechanism includes a water storage tank 1, which is equipped with a partition 11 that divides the water storage tank 1 into a first chamber 12 and a second chamber 13. When the water level in the second chamber 13 exceeds the partition 11, water flows from the second chamber 13 into the first chamber 12. The water storage tank 1 is provided with an inlet pipe 2 that flows toward the second chamber 13. The first chamber 12 is equipped with a heater 121, a first temperature sensor 122, and a liquid level sensor 123. It also includes a first pipe 3 and a second pipe 4, which are respectively connected to the first chamber 12. A mixing pipe 6 is formed by connecting the first pipe 3 and the second pipe 4. The other end of the first pipe 3 is connected to the first chamber 12, and the other end of the second pipe 4 is connected to the second chamber 13. The mixing pipe 6 is equipped with a spray bar 61. The first pipe 3 is equipped with a first flow control valve 31, the second pipe 4 is equipped with a second flow direction control valve 41, and the inlet pipe 2 is equipped with a fourth flow control valve 21. The system also includes a controller, which is electrically connected to the first flow control valve 31, the second flow direction control valve 41, the fourth flow control valve 21, the heater 121, the liquid level sensor 123, and the first temperature sensor 122.

[0018] 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 into the first chamber 12. The heater 121 stores warm water in the first chamber 12. Then, according to the user's input command, the cleaning water circuit mechanism of this utility model has three water outlet modes: cold water outlet mode, warm water outlet mode, and alternating cold and warm water outlet mode. Users can choose as needed to improve the comfort of using the toilet.

[0019] In the cold water outlet mode, the controller opens the second flow control valve 41 to supply water through the second chamber 13.

[0020] In the warm water output mode, the controller controls the first flow control valve 31 to open, or controls the first flow control valve 31 and the second flow control valve to open simultaneously, based on the target temperature input by the user or the target temperature preset by the controller, so as to adjust the water output temperature of the spray bar 61 to the above-mentioned target temperature.

[0021] The alternating cold and warm water output mode is achieved by the controller alternately controlling the output water flow of the first flow control valve 31 and the second flow control valve. Warm and cold water are transported through the first pipeline 3 and the second pipeline respectively, without interference to avoid affecting the outlet water temperature. Furthermore, compared to the prior art which uses an instant heater 52 for heating, this invention uses a heater 121 to ensure stable water output.

[0022] It also includes a third pipeline 5, which is equipped with a third flow control valve 51 and an instant heater 52. One end of the third pipeline 5 is connected to the inlet pipe, and the other end is connected to the mixing pipe 6. The third flow control valve 51 and the instant heater 52 are electrically connected to the controller. When the warm water in the first chamber 12 is used up, the temperature is adjusted by the instant heater 52, thereby maintaining warm water for a longer period of time and improving the user experience.

[0023] The device can place medications for hemorrhoids, perianal eczema, etc., into the first chamber 12, and then use the warm water outlet mode of this invention to achieve a local medicated bath effect on the human body, improve the treatment effect, and also promote blood circulation.

[0024] The alternating hot and cold water mode can promote blood circulation in the perianal area by frequently switching between cold and warm water, relieving discomfort and fatigue caused by prolonged sitting. The alternation of hot and cold water provides a massage-like experience. Furthermore, for users suffering from hemorrhoids, perianal eczema, or other conditions, the alternating hot and cold water can stimulate the skin and relieve pain.

[0025] The third pipeline 5 is also equipped with a switch valve 53 connected to the controller. After the heater 52 heats the water in the third pipeline 5, the controller controls the switch valve 53 to open.

[0026] Reference Figure 2 As shown, it also includes a cover plate 15 that covers 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 downward at an angle toward the valve 16, and the valve 16 is electrically connected to the controller. This allows water to overflow over the partition 11 and flow along the cover plate 15 into the valve 16. The partition 11 and the cover plate 15 are made of insulating material. When water needs to be injected into the first chamber 12, the controller controls the valve 16 to open.

[0027] The water storage tank 1 is provided with a pressure relief hole 14, and a pressure relief valve is installed in the pressure relief hole 14. The pressure relief valve is electrically connected to the controller. When the water level sensor detects that the water level in the water storage tank 1 is too high, the controller controls the pressure relief valve to open. As another embodiment, a pressure-bearing component is installed in the pressure relief hole 14. The pressure-bearing component replaces the pressure relief valve. When the water pressure is greater than the pressure bearing capacity of the pressure-bearing component, the pressure-bearing component can no longer bear the pressure and thus releases pressure.

[0028] A booster pump 62 is installed in the mixing pipe 6. During the water output process, the third temperature sensor 63 detects that the output water temperature meets the target temperature. After the controller completes the temperature adjustment, the booster pump 62 is activated again, allowing the water flow to impact the human body again, making the water flow more abundant and meeting the user's demand for water flow intensity. In addition, considering that there may be residual water or water contaminated by external sources in the spray bar 61, this water is discharged during the temperature adjustment stage, ensuring that the water used by the human body is clean.

[0029] One-way valves are installed in the first pipeline 3, the second pipeline 4 and the third pipeline 5. By setting one-way valves, water backflow can be prevented.

[0030] Specifically, the control method for the cleaning water circuit mechanism includes the following steps:

[0031] S1. When the controller receives a cold water outlet mode command from the user, it proceeds to step S2; when the controller receives a warm water outlet mode command from the user, it proceeds to step S3; when the controller receives an alternating water outlet mode command from the user, it proceeds to step S4.

[0032] S2. The controller controls the second flow control valve to open, and supplies water to the spray bar 61 through the second pipeline 4;

[0033] S3. The warm water outlet mode includes the following control steps:

[0034] 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;

[0035] S32. When the controller detects that the first flow control valve 31 is in the open state and the height of the liquid level sensor 123 is lower than the first set height, the controller controls the fourth flow control valve 21 and the heater 121 to open.

[0036] S33. When the controller detects that the first flow control valve 31 is in the open state, and the temperature of the first temperature sensor 122 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.

[0037] S4. The controller achieves 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.

[0038] Through steps S31 to S33, the cleaning water circuit mechanism can maintain a constant output temperature of warm water for a long time, and when the water level in the first chamber 12 drops below the first set height, water replenishment and heating are performed simultaneously.

[0039] In step S32, the spray bar 61 of the present invention can be selected to have multiple water flow rates, namely low flow rate setting: about 2-5 mL / s, medium flow rate setting: about 5-10 mL / s, and high flow rate setting: about 10-20 mL / s.

[0040] In step S32, when there is still a certain amount of water in the first chamber 12, auxiliary heating is carried out by heater 121, which can reduce the overall power consumption of the cleaning water circuit mechanism.

[0041] In step S33, when the water flow in the first chamber 12 is too low, the instant heater 52 provides auxiliary heating, causing the water from the first pipe 3 and the third pipe 5 to mix in the mixing pipe 6 before being sprayed out through the spray bar 61. The advantage is that the instant heater 52 does not need to operate at full load at this time, reducing the overall power consumption of the cleaning water system.

[0042] Since the incoming water flows into the second chamber 13 and the third pipe 5 respectively, the temperature detected by the second temperature sensor 131 is either the water temperature of the third pipe 5 or the water temperature of the second chamber 13.

[0043] Furthermore, in step S32, the water flow rate m4 per unit time of the fourth flow control valve 21 is calculated using the following formula:

[0044]

[0045] In the formula: 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 detection temperature of the second temperature sensor 131, and T X The target temperature input by the user or the target temperature preset by the controller.

[0046] The relationship between water consumption and the output power of heater 121 is adjusted in real time using the above formula, thereby ensuring a constant outlet water temperature.

[0047] In a further step S33, the water flow rate m3 per unit time of the third flow control valve 51 is calculated using the following formula:

[0048]

[0049] In the formula: t is the unit time, P2 is the output power of the instant heater 52, c is the specific heat capacity of water, T1 is the detection temperature of the first temperature sensor 122, T2 is the detection temperature of the second temperature sensor 131, and T X The target temperature input by the user or the target temperature preset by the controller.

[0050] The relationship between water consumption and the output power of the instantaneous water heater 52 is adjusted in real time using the above formula, thereby ensuring a constant outlet water temperature.

[0051] Step S3 further includes step S34;

[0052] Step S34: When the liquid level sensor 123 detects that the water flow in the first chamber 12 has been exhausted and the instant heater 52 has stopped working, a signal is transmitted to the controller. 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. Then, the controller controls the heater 121 to start. This avoids the heater 121 and the instant heater 52 working simultaneously, which could overload the household circuit and cause a circuit breaker trip.

[0053] Furthermore, in step S32, the first set height is any value from 2 / 3H to H, where H is the highest height that the chamber can accommodate.

[0054] Furthermore, in step S33, the second set height is any value between 0 and 1 / 3H, where H is the highest height that the first chamber 12 can accommodate.

[0055] 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 Exceeding 3°C. When the temperature difference exceeds 3°C, it is a temperature that the human body can clearly perceive. At this time, the instant water heater 52 compensates for the temperature, which can maintain the outlet water temperature and improve the user experience.

[0056] Furthermore, step S33 also includes step S331; in step S331, when the controller detects that the temperature of the first temperature sensor 122 is equal to that of the second sensor, the controller controls the first flow control valve 31 to close, so that the water flows out through the instant heater 52 after being heated.

[0057] Furthermore, step S31 includes the following steps:

[0058] S311. Based on the target temperature input by the user or the target temperature preset by the controller, the controller acquires 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 simultaneously and adjust the outlet water temperature. At this time, warm water in the first chamber 12 and cold water in the second chamber 13 are supplied simultaneously to reduce the mixed outlet water temperature, making the outlet water temperature equal to the aforementioned target temperature.

[0059] Furthermore, in step S311, the opening ratio of the water flow rate m1 per unit time of the first flow control valve 31 and the water flow rate m2 per unit time of the second flow control valve is calculated using the following formula:

[0060]

[0061] In the formula: T1 is the temperature detected by the first temperature sensor 122, T2 is the temperature detected by the second temperature sensor 131, and T X The target temperature input by the user or the target temperature preset by the controller.
