Description

A large-flow cleaning water supply method for toilet, water supply system and toilet Technical Field

The invention relates to the field of sanitary ware, in particular to a toilet.

Background Art

Smart toilets can generate warm water to clean the user's private parts after the user uses the toilet. Compared with the traditional wiping method with toilet paper, the cleaning effect of warm water cleaning is better and is liked by many users.

Conventional instant hot water supply systems for cleaning water basically include electromagnetic pressure reducing valves, heating components, water diversion valves, and spray washing devices. However, due to the power limit of the instant hot water module, the national standard temperature rise requirements, and the restrictions on the cleaning water consumption standards (the country advocates energy conservation and water conservation), the cleaning flow rate on the market is basically around 600ml/min, which can meet basic cleaning needs. However, the experience of high-flow cleaning (>800ml/min) is definitely not comparable to conventional cleaning. For users with body hair at the anus, high-flow cleaning can clean it more thoroughly; and for people with constipation, they need a large flow and high cleaning force to squeeze water into the rectum to lubricate the intestines, soften feces, stimulate the urge to defecate, and assist defecation.

For this reason, some companies on the market use large water tanks and booster pumps to provide large flow, or water tanks + instant heating + circulation pumps to provide large flow. This method requires that the water is always kept in the water tank, so that when not in use, the water in the water tank must be continuously heated to maintain the water temperature. Therefore, there is a serious problem of energy waste, and continuous heating will also create noise. At the same time, this method The cost of this solution is high, and it uses recycled water, which is easily contaminated and scaled, and is not a good large-flow cleaning solution.

Regardless of which of the two methods is used, the water heating action is started only when the user needs to perform a high-flow flush, and there is no need to heat and keep the water warm all the time. This greatly saves power consumption and reduces the cost of use.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set/connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a wall-mounted connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a through connection. Indirect connection through an intermediate medium may be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Referring to FIG1 , this embodiment provides a method for supplying high-flow water to a toilet, comprising the following steps:

1) Obtain the inlet water temperature T1;

2) Compare the inlet water temperature T1 with the set temperature T2. If the inlet water temperature T1 is higher than the set temperature T2, proceed to step 3; if the inlet water temperature T1 is lower than the set temperature T2, proceed to step 4;

3) The water is heated to the cleaning temperature T3 by the heating component at a large flow rate for cleaning;

4) The water is heated at a low flow rate to the cleaning temperature T3 by the heating component and then stored in the water tank until the water volume in the water tank reaches the set threshold value for cleaning.

The set temperature T2 is the minimum inlet water temperature calculated based on the power of the heating component, the cleaning temperature T3 and the amount of water required for large-flow cleaning. As long as the inlet water temperature T1 is higher than this value, the heating component can heat the water to the cleaning temperature T3 while meeting the requirements of large-flow cleaning. If it is lower than this value, the heating component cannot heat the water to the cleaning temperature T3 while meeting the requirements of large-flow cleaning. Therefore, the set temperature T2 is calculated by the specific heat capacity equation Q=cmΔT, where Q is the power of the heating component, c is the specific heat capacity, m is the mass of water, and ΔT is the difference between the cleaning temperature T3 and the set temperature T2. Since the other parameters in the above formula are known, the set temperature T2 can be calculated.

When the inlet water temperature T1 is lower than the set temperature T2, the water needs to be temporarily stored in the water tank. When the water in the water tank meets the large flow rate for cleaning, the water needs to be discharged from the water tank. To this end, it is necessary to detect whether the water in the water tank has reached the set threshold. The basis for the diagnosis is the liquid level in the water tank.

In addition, after the water enters the water tank for temporary storage, it needs to be pressurized to meet the needs of large-flow cleaning when it is discharged. Therefore, when the water volume in the water tank reaches the set threshold, it is pressurized by the liquid pump for large-flow cleaning.

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

In order to realize the above-mentioned large-flow cleaning water supply method, referring to FIGS. 2-5 , this embodiment also provides a large-flow cleaning water supply system for a toilet, comprising: an inlet water temperature sensor 1, a liquid pump 2, a heating assembly 3 and a spraying device 4; the inlet water temperature sensor 1 is arranged between the inlet valve 5 and the water inlet end of the liquid pump 2;

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 component 3;

A first three-way switching valve 7 is also provided between the water inlet temperature sensor 1 and the water inlet end of the liquid pump 2, wherein a first water outlet of the first three-way switching valve 7 is connected to the water inlet end of the liquid pump 2, and a second water outlet is directly connected to the heating component 3; a second three-way switching valve 8 is also connected to the water outlet end of the liquid pump 2, wherein a first water outlet of the second three-way switching valve 8 is connected to the spraying device 4 via the heating component 3, and a second water outlet of the second three-way switching valve 8 is directly connected to the spraying device 4;

The temperature signal generated by the inlet water temperature sensor 1 and used to represent the inlet water temperature T1 is sent to the main control unit, and the main control unit compares the inlet water temperature T1 with the set temperature T2. Compare.

If the inlet water temperature T1 is higher than the set temperature T2, the main control unit sends a control signal to connect the water inlet valve 5 and the first water outlet of the first three-way switching valve 7, and connect the water outlet end of the liquid pump 2 with the first water outlet of the second three-way switching valve 8; at this time, the water flowing into the water inlet valve 5 is pressurized by the liquid pump 2 and enters the heating component 3 for high-flow heating to the cleaning temperature T3, and then directly performs high-flow cleaning.

If the inlet water temperature T1 is lower than the set temperature T2, the main control unit sends a control signal to connect the inlet valve 5 with the second water outlet of the first three-way switching valve 7, and connect the water outlet of the liquid pump 2 with the second water outlet of the second three-way switching valve 8. At this time, the water flowing into the inlet valve 5 directly passes through the heating component 3 to be heated to the cleaning temperature T3 at a small flow rate and then enters the water tank 6 for temporary storage. When the amount of water 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 water temporarily stored in the water tank 6 for large flow rate cleaning.

In addition to high-flow cleaning, the spray rod of the toilet also has the functions of buttocks washing and women's washing. Therefore, the water outlet end of the heating component 3 is connected to the third three-way switching valve 9, the first water outlet of the third three-way switching valve 9 is connected to the spray washing device 4 through the water diverter valve 10, and the second water outlet of the third three-way switching valve 9 is connected to the water inlet end of the water tank 6. In this way, when the user needs to perform buttocks washing or women's washing, the water inlet valve 5 and the second water outlet of the first three-way switching valve 7 can be connected, and the water can be heated by the heating component 3 and sprayed from the buttocks washing outlet 41 or the women's washing outlet 42 of the spray washing device 4 through the water diverter valve 10 to achieve buttocks washing or women's washing.

In order to determine whether the amount of water in the water tank 6 meets the requirements for large-flow cleaning, the water tank 6 is provided with a liquid level sensor 61; the liquid level sensor 61 generates a signal indicating that the liquid level in the water tank 6 is high. A low liquid level signal is sent 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 it to the spraying device 4.

The above cleaning process can be summarized as follows:

1. Conventional hip wash and feminine wash: When performing hip wash or feminine wash, the electromagnetic water inlet valve 5 opens the external water supply, the first three-way switching valve 7 opens the direct heating component 3 channel, the third three-way switching valve 9 opens the direct water diverter valve 10 channel, and the water diverter valve 10 opens the corresponding hip wash or feminine wash channel, and sprays out through the hip wash outlet 41 or the feminine wash outlet 42 of the spray device 4 to complete the conventional cleaning function.

2. Inlet water temperature T1>set temperature T2, large flow cleaning mode: the water inlet valve 5 opens the external water supply. When the inlet water temperature T1 detected by the inlet water temperature sensor 1 is greater than the set temperature T2, the first three-way switching valve 7 opens the direct liquid pump 2 channel, and the liquid pump 2 starts pressurizing. The second three-way switching valve 8 opens the direct heating component 3 channel. The third three-way switching valve 9 opens the direct water diverter valve 10 channel. The water diverter valve 10 turns to the large flow cleaning channel, and sprays out through the large flow outlet 43 of the spray device 4 to complete the large flow cleaning function.

3. Inlet water temperature T1 ≤ set temperature T2, large flow cleaning: the electromagnetic inlet valve 5 opens the external water supply. When the inlet water temperature T1 detected by the inlet water temperature sensor 1 is ≤ set temperature T2, the first three-way switching valve 7 opens the direct heating component 3, and the third three-way switching valve 9 opens the direct water tank 6 channel. The instantly heated water flows into the water tank 6 until the liquid level sensor 61 senses the specified water level. The liquid pump 2 is turned on, and the second three-way switching valve 8 opens the direct spraying device 4 to complete the large flow cleaning function.

The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any technician familiar with the technical field disclosed in the present invention can Any non-substantial changes to the present invention using this conception shall be deemed as an infringement of the protection scope of the present invention.
