Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of water storage method of intelligent toilet flushing water and its implementation device, in particular to water storage method of intelligent toilet water tank and its implementation device. BACKGROUND

[0002] Intelligent toilet is provided with two independent water paths, one is the flushing water path connecting flushing water tank and ceramic body, for flushing ceramic body toilet, the other is the cleaning water path connecting cleaning water tank and intelligent cover plate cleaning assembly, for cleaning human body. Cleaning water path requires high water quality, and flushing water path has the possibility of backflow, therefore, in order to prevent cleaning water path from being contaminated, flushing water path and cleaning water path are required to be independent. Usually, flushing water path is supplied by flushing water tank, and flushing water tank is installed on intelligent toilet ceramic body, while cleaning water path is supplied by cleaning water tank, and cleaning water tank is installed on intelligent toilet cover plate. Of course, there is also a way of connecting cleaning water tank directly with external water path through electromagnetic valve switch, but each has its advantages and disadvantages, and consumers can choose by themselves. For the way of supplying cleaning water path by cleaning water tank, as cleaning water tank and valve switch and water pump and other components need to occupy a large installation space, which leads to the volume of intelligent toilet cover plate rear shell being large, and it is impossible to make ultra-thin, mini-type intelligent toilet cover plate, which affects the competitiveness of products. SUMMARY

[0004] The application discloses a water storage method for a water tank of a smart toilet. An air storage cavity is arranged at a lower part of a cleaning water tank. The cleaning water tank is arranged in a flushing water tank and below a float of a water inlet valve. After the water inlet valve is opened, water enters the cleaning water tank first, and then enters the flushing water tank after overflowing. Before water is stored for the first time, the water inlet valve is in an open state due to the falling of the float. Water flows into the cleaning water tank from top to bottom after flowing out of the water inlet valve. After the cleaning water tank is filled with water, the water overflows and flows into the flushing water tank. The liquid level in the flushing water tank continuously rises. The cleaning water tank floats on the liquid level of the flushing water tank and rises with the liquid level of the flushing water tank. Finally, the cleaning water tank drives the float of the water inlet valve to rise and close the water inlet valve. When the flushing water tank is drained, the cleaning water tank falls with the liquid level of the flushing water tank. The water inlet valve is switched to the open state after the float falls. Water overflows the cleaning water tank and flows into the flushing water tank. After the flushing water tank stops draining, the cleaning water tank rises with the liquid level of the flushing water tank as the liquid level of the flushing water tank rises. The cleaning water tank drives the float of the water inlet valve to rise and close the water inlet valve. When the cleaning water tank is drained, the cleaning water tank floats to the upper limit position in the initial stage of draining. At this time, the water inlet valve remains in the closed state. The water inlet valve is switched to the open state after the float of the water inlet valve falls with the liquid level of the cleaning water tank. After the cleaning water tank stops draining, the liquid level of the cleaning water tank rises and drives the float of the water inlet valve to rise and close the water inlet valve.

[0005] In a preferred embodiment, when the water inlet valve fails to stop water and the liquid level in the flushing water tank rises, water in the flushing water tank flows out of an overflow hole of the flushing water tank before the liquid level of the flushing water tank reaches the top surface of the cleaning water tank.

[0006] In a preferred embodiment, the cleaning water tank floats up and down along a limiting column in the flushing water tank. The cleaning water tank rises to the upper limit position when an upper baffle of the limiting column is in close contact with the cleaning water tank.

[0007] In a preferred embodiment, the flushing water tank is installed at the rear part of a ceramic body of the toilet. The cleaning water tank is drained by water pumping, and the water pump is installed at the rear part of the ceramic body of the toilet.

[0009] In a preferred embodiment: the flushing water tank is provided with a vertical limiting column, and the cleaning water tank is movably sleeved on the limiting column.

[0010] In a preferred embodiment: the limiting column is provided with an upper baffle, and during daily use, when only the cleaning water tank is drained, at the initial stage of the drainage, the cleaning water tank floats up and leans against the upper baffle, and the water inlet valve still remains in the closed state; when the float of the water inlet valve descends together with the liquid level of the cleaning water tank, the water inlet valve switches to the open state.

[0011] In a preferred embodiment: the limiting column is provided with a lower baffle, and during daily use, when the flushing water tank is drained, the cleaning water tank falls on the lower baffle.

[0014] Compared with the background art, the technical solution has the following advantages:

[0015] 1. The cleaning water tank is arranged in the flushing water tank, and the cleaning water tank can float up and down with the flushing water tank, so that the water in the flushing water tank cannot be mixed into the cleaning water tank reversely, the installation space of the cleaning water tank can be saved for the intelligent cover plate of the closestool, the intelligent cover plate of the closestool is thinned, the water supplement of the cleaning water tank and the flushing water tank is controlled through the same water inlet valve, the structure inside the intelligent cover plate of the closestool is reduced, the intelligent cover plate of the closestool is thinned further, and the components of the intelligent closestool are less.

[0016] 2. When the water inlet valve fails to stop water normally, the liquid level in the flushing water tank rises, and finally flows out from the overflow hole. Similarly, if the water in the ceramic body basin flows back to the flushing water tank, the water in the flushing water tank will also finally flow out from the overflow hole, so that the liquid level in the flushing water tank is prevented from rising continuously and mixing into the cleaning water tank.

[0024] The utility model discloses a water storage method of the water tank of the intelligent closestool, and the water storage or water supplement of the cleaning water tank and the flushing water tank is controlled in linkage, the structure is simplified, and the installation space is saved, and specifically:

[0025] The gas storage cavity is arranged at the lower part of the cleaning water tank. The cleaning water tank can be regarded as a float structure with water storage function, that is, the cleaning water tank can float on the water surface. The cleaning water tank is arranged in the flushing water tank and below the float of the water inlet valve. Since the cleaning water tank is below the water inlet valve, when the water inlet valve is opened for water replenishment or storage, the water flows out of the water inlet valve and first enters the cleaning water tank, and then flows into the flushing water tank after overflowing from the cleaning water tank.

[0026] Before the first water storage, that is, when the cleaning water tank and the flushing water tank are both empty, the water inlet valve is in the open state due to the falling of the float. The water flows into the cleaning water tank from top to bottom after flowing out of the water inlet valve. The liquid level in the cleaning water tank rises continuously. When the cleaning water tank is filled with water, the water overflows from the cleaning water tank and then flows into the flushing water tank. Then, the liquid level in the flushing water tank rises continuously. The cleaning water tank floats on the liquid surface of the flushing water tank and rises with the liquid surface of the flushing water tank. That is, after the cleaning water tank floats on the liquid surface of the flushing water tank, the liquid level in the cleaning water tank rises with the rising of the cleaning water tank. Finally, the cleaning water tank drives the float of the water inlet valve to rise and thus closes the water inlet valve, stopping water replenishment. The above process is described with reference to Figure 3 .

[0027] During daily use, when the flushing water tank is draining, the water in the flushing water tank decreases rapidly, the liquid level in the flushing water tank decreases, the cleaning water tank descends with the liquid surface of the flushing water tank, and the float of the water inlet valve falls after losing the support of the cleaning water tank. The water inlet valve is switched to the open state after the float falls. The water in the cleaning water tank flows into the flushing water tank after overflowing from the cleaning water tank. When the flushing water tank stops draining, the liquid level in the flushing water tank rises, the cleaning water tank floats on the liquid surface of the flushing water tank and rises with the liquid surface of the flushing water tank, and the cleaning water tank drives the float of the water inlet valve to rise and thus closes the water inlet valve. The above process is described with reference to Figure 4 .

[0028] During daily use, when the cleaning water tank is draining, at the initial stage of draining, the weight of the entire cleaning water tank decreases with the draining of the water in the cleaning water tank. Thus, under the action of buoyancy, the cleaning water tank further floats up with the decrease of its own weight and reaches the upper limit position, which is understood as that the cleaning water tank is blocked and cannot further float up. Although the water in the cleaning water tank decreases at the initial stage of draining, the cleaning water tank further floats up at the same time. Therefore, the liquid level in the cleaning water tank does not decrease, and thus the float of the water inlet valve does not fall. At this time, the water inlet valve remains in the closed state. Subsequently, the liquid level in the cleaning water tank continuously decreases with the continuous draining of the water in the cleaning water tank. When the float of the water inlet valve descends with the liquid surface of the cleaning water tank, that is, the float finally falls, the water inlet valve is switched to the open state. Subsequently, the cleaning water tank stops draining, the liquid level in the cleaning water tank rises, and finally drives the float of the water inlet valve to rise and thus closes the water inlet valve. The above process is described with reference to Figure 5 .

[0029] Please refer to the following Figures 1 to 5 , the water storage device for implementing the intelligent toilet cistern water storage method is further described.

[0030] The water storage device includes a cleaning cistern 10, a flushing cistern 20, and a water inlet valve 30 arranged in the flushing cistern 20 and located at the top of the flushing cistern. The cleaning cistern 10 is arranged in the flushing cistern 20 and located directly below the float 32 of the water inlet valve 30. The cleaning cistern 10 can float up and down, that is, move up and down. The flushing cistern 20 is connected to the toilet bowl 52 of the ceramic body 50 through a flushing waterway 40, and the cleaning cistern 10 is connected to the cleaning assembly 72 of the intelligent cover plate 70 through a cleaning waterway 60. The ceramic body and its toilet bowl, the intelligent cover plate and its cleaning assembly are all existing structures. The lower part of the cleaning cistern 10 is provided with a gas storage cavity 12, so that the cleaning cistern 10 not only stores water but also can float on the water surface. When the water inlet valve 30 is filled with water, the water first enters the cleaning cistern 10 and then enters the flushing cistern 20 after overflowing.

[0031] In the initial state, the flushing cistern 20 and the cleaning cistern 10 are both empty, and the float 32 of the water inlet valve 30 naturally falls to open the water inlet valve (as shown in Figure 2 ). After starting to fill water, when the cleaning cistern 10 is filled with water, the water overflows into the flushing cistern 20 (as shown in Figure 3 a small figure), the liquid level in the flushing cistern 20 rises, and the cleaning cistern 10 floats in the flushing cistern 20 (as shown in Figure 3 b small figure), then the cleaning cistern 10 floats on the liquid surface of the flushing cistern 20 and rises with the liquid surface of the flushing cistern until the cleaning cistern drives the float 32 of the water inlet valve 30 to rise and close the water inlet valve (as shown in Figure 3 c small figure), at this time, the liquid level in the flushing cistern 20 reaches the working water level line WL. Since the float 32 uses a structure with weighted water in this embodiment, after the water inlet valve 30 is closed, the weight of the float 32 is reduced as the weighted water in the float 32 flows out, and the float 32 will further float up under the action of buoyancy to ensure that the water inlet valve is stable (as shown in Figure 3 d small figure). The structure of the float with stored weighted water belongs to the existing structure and will not be described in detail.

[0032] In the daily use process, when it is necessary to fill water in the cleaning cistern 10 and the flushing cistern 20 at the same time, that is, the flushing waterway 40 and the cleaning waterway 60 are both opened, the water filling process is the same as the initial state, that is, the process shown in Figure 3 .

[0033] When only the flushing water tank 20 is replenished, that is, when only the flushing water passage 40 is opened, during the replenishment process, the liquid level in the flushing water tank 20 rises, causing the cleaning water tank 10 to float. The cleaning water tank 10 then causes the float 32 of the inlet valve to rise, thereby closing the inlet valve 30. Specifically, when the flushing water tank 20 drains water, the water volume in the flushing water tank decreases rapidly, and the liquid level in the flushing water tank drops below the working water level line WL (e.g., Figure 4 As shown in small figure b), the water level in the cleaning tank 10 drops along with the water level in the flushing tank 20. The inlet valve float 32, losing its support from the cleaning tank 10, falls. After the float falls, the inlet valve 30 switches to the open state, and water overflows from the cleaning tank 10 and flows into the flushing tank 20. When the flushing tank 20 stops draining, as the water level in the flushing tank 20 rises, the cleaning tank 10 floats on the flushing tank's surface and rises along with it. The cleaning tank causes the inlet valve float to rise, thus closing the inlet valve (as shown in small figure b). Figure 4 (See small figures c and d).

[0034] When only the cleaning water tank 10 is replenished, that is, when only the cleaning water passage 60 is opened, the liquid level in the cleaning water tank 10 rises, causing the float 32 of the inlet valve to rise and thus close the inlet valve. Specifically, during the initial drainage of the cleaning water tank 10, as the water in the cleaning water tank 10 is discharged, the weight of the entire cleaning water tank 10 is reduced. Thus, under the action of buoyancy, the cleaning water tank 10 will float further upwards as its weight decreases (e.g., ...). Figure 5 (As shown in small figure a). Although the water volume in the cleaning tank decreases during the initial drainage, the cleaning tank also rises further. Therefore, the liquid level in the cleaning tank does not decrease relative to the float 32, so the inlet valve float does not fall, and the inlet valve 30 remains closed. Afterwards, as water is continuously discharged from the cleaning tank, the liquid level in the cleaning tank 10 continues to decrease. When the inlet valve float 32 falls along with the liquid level in the cleaning tank, i.e., the float finally falls, the inlet valve 30 switches to the open state (as shown in small figure a). Figure 5 (As shown in small diagram b). Afterwards, the cleaning water tank 10 stops draining, and the liquid level in the tank rises, eventually causing the float of the inlet valve to rise and close the inlet valve (as shown in small diagram b). Figure 5 (As shown in small diagram c). Finally, the counterweight water inside float 32 flows out, and float 32 will rise further to ensure stable water stoppage of the inlet valve (as shown in small diagram c). Figure 5 (as shown in the small diagram d).

[0035] Although the water storage device of this utility model has the cleaning water tank 10 built into the flushing water tank 20, the cleaning water tank 10 can float in the flushing water tank 20, ensuring that the cleaning water path 60 is relatively independent.

[0036] Preferably, the flushing water tank 20 is provided with a vertical limiting column 22, and the cleaning water tank 10 is movably sleeved on the limiting column 22. Thus, the cleaning water tank 10 floats up and down along the limiting column 22 in the flushing water tank, so that the cleaning water tank can be better ensured to be below the water inlet valve float when the cleaning water tank is small, and the water flow enters the cleaning water tank first when water is replenished.

[0037] Preferably, the limiting column 22 is provided with an upper baffle 24. During daily use, when only the cleaning water tank 10 is drained, the cleaning water tank 10 floats up and leans against the upper baffle 24 at the initial stage of draining, and the cleaning water tank 10 rises to an upper limit position while the water inlet valve remains in a closed state. When the float of the water inlet valve falls with the liquid surface of the cleaning water tank, the water inlet valve switches to an open state. Of course, if the cleaning water tank 10 rises and leans against the water inlet valve itself, the cleaning water tank 10 can also be maintained at an upper limit position, that is, the water inlet valve is used to limit the upper limit position of the cleaning water tank 10, or if the space in the flushing water tank is large enough, the upper limit position can also be unnecessary, as long as the water in the cleaning water tank 10 is drained, the float 32 will naturally fall.

[0038] Preferably, the limiting column 22 is provided with a lower baffle 26. During daily use, when the flushing water tank 20 is drained, the cleaning water tank 10 falls on the lower baffle 26.

[0039] Preferably, the flushing water tank 20 is provided with an overflow hole, the height of the overflow hole is higher than the liquid level in the flushing water tank 20 during daily use, that is, the working water level line WL, and is lower than the liquid level in the cleaning water tank 10 during daily use. Thus, when the water inlet valve 30 fails to stop water and causes the liquid level in the flushing water tank to rise, the water in the flushing water tank flows out from the overflow hole of the flushing water tank before the liquid level in the flushing water tank reaches the top surface of the cleaning water tank 10, that is, the liquid level in the cleaning water tank.

[0040] Preferably, the flushing water tank 20 is installed at the rear of the ceramic body 50 of the closestool.

[0041] Preferably, the cleaning water tank 10 is drained by water pumping of the water pump 14, that is, the cleaning water channel 60 is provided with the water pump 14, and the water pump 14 is installed at the rear of the ceramic body 50 of the closestool.

[0042] Preferably, the flushing water tank 20 is drained by water pumping of the water pump 28, that is, the flushing water channel 40 is provided with the water pump 28, and the water pump 28 is installed at the rear of the ceramic body 50 of the closestool.

[0043] The above description is only the preferred embodiment of the present application, and therefore cannot limit the scope of the present application. Any equivalent changes and modifications made according to the scope and content of the present application should still be within the scope of the present application.
