Description

TECHNICAL FIELD

[0001] The present application relates to the field of bathroom, in particular to a toilet. BACKGROUND

[0002] The intelligent toilet can generate warm water to clean the private parts of the user after the user uses the toilet. Compared with the traditional toilet paper wiping method, the cleaning effect of the warm water cleaning is better, and is liked by many users.

[0003] The conventional instant cleaning water supply system basically includes an electromagnetic pressure reducing valve, a heating assembly, a water distribution valve and a spray cleaning device. However, due to the limitation of the power of the instant heating module, the national standard temperature rise requirement and the cleaning water volume standard (the state advocates energy saving and water saving), the cleaning flow on the market is basically around 600 ml / min, which can meet the basic cleaning demand. However, the experience of the user is absolutely not comparable to the conventional cleaning for the user with body hair in the anus, and the high-flow cleaning can clean more thoroughly. In addition, the high-flow cleaning can help the constipation group to squeeze water into the rectum, lubricate the intestinal tract, soften the feces, stimulate the defecation intention and assist defecation.

[0004] Therefore, some enterprises on the market provide high flow by using a large water tank and a booster pump, or provide high flow by using a water tank, an instant heating and a circulating pump. This method needs to always save water in the water tank, so that the water in the water tank needs to be heated constantly to maintain the water temperature when not in use, thereby causing serious waste of electric energy. In addition, continuous heating also generates noise. At the same time, this scheme has high cost, and uses circulating water, which is easy to be contaminated and scale, and is not a good solution for high-flow cleaning. SUMMARY

[0005] The main technical problem to be solved by the present application is to provide a toilet high-flow cleaning water supply method, which can flexibly adopt different high-flow cleaning schemes according to different inlet water temperatures, without always heating and keeping the water warm, thereby reducing the cost and improving the user experience.

[0019] The temperature signal generated by the water inlet temperature sensor to indicate the water temperature is sent to the main control unit, the main control unit compares the water temperature with the set temperature, if the water temperature is higher than the set temperature, the main control unit sends a control signal to connect the water inlet valve and the first water outlet of the first three-way switch valve, and to connect the water outlet end of the liquid pump and the first water outlet of the second three-way switch valve; if the water temperature is lower than the set temperature, the main control unit sends a control signal to connect the water inlet valve and the second water outlet of the first three-way switch valve, and to connect the water outlet end of the liquid pump and the second water outlet of the second three-way switch valve.

If so, the inlet water is pressurized by the pump, heated by the heating assembly and used for large flow cleaning. If the temperature of the inlet water is too low, the water is first heated by the heating assembly to the flushing temperature and temporarily stored in the water tank, and then pressurized by the pump for large flow cleaning when the amount of water in the water tank reaches the amount of water required for large flow flushing. No matter which of the two methods is used, the water heating action is started only when the user needs to perform large flow flushing, and there is no need to heat and keep the water warm all the time. This greatly saves the power consumption and reduces the use cost. BRIEF DESCRIPTION OF DRAWINGS

[0033] Reference Figure 1 The present embodiment provides a large-flow cleaning water supply method for a toilet, comprising the following steps:

[0034] 1) Obtain the water inlet temperature T1;

[0035] 2) Compare the water inlet temperature T1 with the set temperature T2, if the water inlet temperature T1 is higher than the set temperature T2, go to step 3; if the water inlet temperature T1 is lower than the set temperature T2, go to step 4;

[0036] 3) Large-flow heating of water to the cleaning temperature T3 by the heating assembly, and then cleaning;

[0037] 4) Low-flow heating of water to the cleaning temperature T3 by the heating assembly, and then storing in the water tank until the water amount in the water tank reaches the set threshold, and then cleaning.

[0038] The set temperature T2 is the lowest water inlet temperature calculated according to the power of the heating assembly, the cleaning temperature T3 and the water quantity required to meet the large-flow cleaning. As long as the water inlet temperature T1 is higher than the value, the heating assembly can heat the water to the cleaning temperature T3 under the premise of meeting the large-flow cleaning. If the water inlet temperature T1 is lower than the value, the heating assembly cannot heat the water to the cleaning temperature T3 under the premise of meeting the large-flow cleaning. Therefore, the set temperature T2 is calculated by the specific heat equation Q = cmΔT, wherein Q is the power of the heating assembly, c is the specific heat capacity, m is the mass of the water, and ΔT is the difference between the cleaning temperature T3 and the set temperature T2. Since other parameters in the above equation are known, the set temperature T2 can be calculated.

[0039] Since the water needs to be temporarily stored in the water tank when the water inlet temperature T1 is lower than the set temperature T2, the water needs to be discharged from the water tank when the water in the water tank meets the large-flow cleaning. Therefore, it is necessary to detect whether the water in the water tank reaches a set threshold. In the embodiment, the basis for the above judgment is the liquid level in the water tank.

[0040] In addition, after the water enters the water tank for temporary storage, the water discharged from the water tank needs to be pressurized to meet the requirement of the large-flow cleaning. Therefore, when the water quantity in the water tank reaches the set threshold, the water is pressurized by the liquid pump and then used for the large-flow cleaning.

[0041] When the water inlet temperature T1 is higher than the set temperature T2, the heating assembly can directly heat the water to the set temperature T2. Therefore, at this time, the external water supply can be pressurized by the liquid pump and then delivered to the heating assembly for large-flow heating. When the water inlet temperature T1 is lower than the set temperature T2, the external water supply is directly delivered to the heating assembly for small-flow heating.

[0042] In order to realize the above-mentioned large-flow cleaning water supply method, with reference to Figures 2-5 The embodiment also provides a large-flow cleaning water supply system of a toilet, which comprises a water inlet temperature sensor 1, a liquid pump 2, a heating assembly 3 and a spray cleaning device 4.

[0043] The water inlet end of the liquid pump 2 is also connected to the water outlet end of a water tank 6, and the water inlet end of the water tank 6 is connected to the water outlet end of the heating assembly 3.

[0044] The first three-way switch valve 7 is arranged between the water inlet temperature sensor 1 and the water inlet end of the liquid pump 2, the first water outlet of the first three-way switch valve 7 is connected to the water inlet end of the liquid pump 2, and the second water outlet is directly connected to the heating assembly 3; the water outlet end of the liquid pump 2 is also connected to the second three-way switch valve 8, the first water outlet of the second three-way switch valve 8 is connected to the spray washing device 4 through the heating assembly 3, and the second water outlet of the second three-way switch valve 8 is directly connected to the spray washing device 4.

[0045] The temperature signal generated by the water inlet temperature sensor 1 for indicating the water inlet temperature T1 is sent to the main control unit, and the main control unit compares the water inlet temperature T1 with the set temperature T2.

[0046] If the water inlet temperature T1 is higher than the set temperature T2, the main control unit sends a control signal to connect the first water outlet of the first three-way switch valve 7 and the water outlet end of the liquid pump 2 to the first water outlet of the second three-way switch valve 8; at this time, the water flowing into the water inlet valve 5 is directly washed at a large flow rate after being heated to the cleaning temperature T3 by the heating assembly 3.

[0047] If the water inlet temperature T1 is lower than the set temperature T2, the main control unit sends a control signal to connect the second water outlet of the first three-way switch valve 7 and the water outlet end of the liquid pump 2 to the second water outlet of the second three-way switch valve 8. At this time, the water flowing into the water inlet valve 5 is directly heated to the cleaning temperature T3 by the heating assembly 3 and then temporarily stored in the water tank 6, and when the water amount in the water tank 6 is sufficient to meet the large flow rate cleaning, the main control unit controls the liquid pump 2 to pressurize the temporarily stored water in the water tank 6 and then perform large flow rate cleaning.

[0048] The spray rod of the toilet has the functions of hip washing and female washing in addition to large flow rate cleaning, so the water outlet end of the heating assembly 3 is connected to the third three-way switch valve 9, the first water outlet of the third three-way switch valve 9 is connected to the spray washing device 4 through the water distribution valve 10, and the second water outlet of the third three-way switch valve 9 is connected to the water inlet end of the water tank 6. In this way, when the user needs to perform hip washing or female washing, the second water outlet of the first three-way switch valve 7 and the water inlet valve 5 are connected, the water is heated by the heating assembly 3, and then sprayed from the hip washing water outlet 41 or the female washing water outlet 42 of the spray washing device 4 through the water distribution valve 10, thereby achieving hip washing or female washing.

[0049] In order to determine whether the water amount in the water tank 6 meets the large flow rate cleaning, the water tank 6 is provided with a liquid level sensor 61; the liquid level sensor 61 generates a liquid level signal indicating the high and low of the liquid level in the water tank 6 and sends the signal to the main control unit, and the main control unit sends a control signal to the liquid pump 2 to pressurize the water in the water tank 6 and then deliver the water to the spray washing device 4.

[0053] 3. Large-flow cleaning: When the water inlet temperature T1 is less than or equal to the set temperature T2, the electromagnetic water inlet valve 5 is opened to supply external water, the first three-way switch valve 7 is opened to supply the straight-through heating assembly 3, the third three-way switch valve 9 is opened to supply the straight-through water tank 6, the water flows into the water tank 6 through the instant heating, and when the liquid level sensor 61 senses the specified water level, the liquid pump 2 is opened, the second three-way switch valve 8 is opened to supply the straight-through spray washing device 4, and the large-flow cleaning function is completed.
