Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of bathroom, in particular to a water tank assembly, a flushing system and a toilet. BACKGROUND

[0002] The control of the waterway of the intelligent toilet is usually in a point-to-point and line-to-line manner. After the waterway is branched from the angle valve, the flushing waterway of the intelligent toilet and the human body cleaning system of the intelligent toilet cover are used separately. The independent control of the waterway has corresponding advantages, such as simple connection logic and no need to consider other associated application relationships. However, the independent control of the waterway also has disadvantages, such as a large number of connecting pipelines between modules and a large number of connecting parts, which results in a large space requirement for installation.

[0003] In addition, the independent control of the waterway also causes the single execution of the functions of the related functional devices, which cannot effectively improve the utilization rate of the devices and causes the waste of the resources of the control board. For example, the functions of controlling the water inlet of the human body cleaning system of the intelligent toilet cover and controlling the flushing system of the intelligent toilet are the same, and the functions of the two are usually not used at the same time. However, the functions of the two are very single after being independent, and two groups of water inlet modules are needed to support the waterway system, which causes the waste of resources.

[0045] As Figures 1-8 As shown in the drawings, the embodiments of the present application provide a water tank assembly 100, which can be used in a toilet and supply water for the toilet, wherein the toilet can be a sitting toilet, a squatting toilet, etc.

[0046] As shown in the drawings, the embodiments of the present application provide a water tank assembly 100, which can be used in a toilet and supply water for the toilet, wherein the toilet can be a sitting toilet, a squatting toilet, etc. Figure 1 , Figure 2As shown, the water tank assembly 100 of the embodiment of the present application comprises a first water tank 1 and a second water tank 2, the second water tank 2 is provided with a communication hole 20 communicated with the first water tank 1 and a control valve 21 controlling the opening and closing of the communication hole 20. The control valve 21 is arranged to be opened or closed under the action of the water pressure difference between the first water tank 1 and the second water tank 2, so as to realize the water supplement of the first water tank 1 to the second water tank 2 or stop the water supplement. The water pressure difference is generated after the water level difference between the first water tank 1 and the second water tank 2 is formed.

[0047] The second water tank 2 of the water tank assembly 100 of the embodiment of the present application realizes the water supplement of the first water tank 1 to the second water tank 2 by arranging the communication hole 20 and the control valve capable of being opened or closed under the action of the water pressure difference between the first water tank 1 and the second water tank 2. Therefore, the second water tank 2 does not need to be designed with a water inlet part separately, thereby reducing the complexity of connection and control, and reducing the cost and saving the space.

[0048] As shown, Figure 6 The control valve 21 in the embodiment can adopt a check valve or a one-way valve. When the water pressure of the first water tank 1 is greater than the water pressure of the second water tank 2, the control valve 21 is opened under the action of the water flow of the first water tank 1 to open the communication hole 20, so that the water in the first water tank 1 flows into the second water tank 2 to supplement the water of the second water tank 2. As shown, Figure 8 When the water pressure of the first water tank 1 is less than or equal to the water pressure of the second water tank 2, the control valve 21 closes the communication hole 20 to prevent the water of the second water tank 2 from flowing back to the first water tank 1. At this time, the second water tank 2 stores water, and the first water tank 1 is used. Of course, the control valve 21 can also adopt other forms of check control mechanism capable of preventing water from flowing back into the first water tank 1, which is not limited herein.

[0049] As shown, Figure 8 The highest water level of the second water tank 2 is lower than or equal to the highest water level of the first water tank 1, so as to realize that the first water tank 1 can fully supplement the water of the second water tank. The lowest liquid level of the second water tank 2 is higher than or equal to the lowest liquid level of the first water tank 1, so as to prevent the second water tank 2 from being too low, which causes the control valve 21 to be always in the opened state under the action of the water pressure and the water gravity of the first water tank 1 when the second water tank 2 is supplemented with water, thereby causing the control valve 21 to be unable to be closed.

[0050] As shown, Figure 2 The second water tank 2 is arranged outside the first water tank 1 and communicated with the first water tank 1 through a pipeline. The volume of the second water tank 2 is less than the volume of the first water tank 1. The bottom of the second water tank 2 is communicated with the bottom of the first water tank 1 through a pipeline, so that the first water tank 1 can also supplement the water of the second water tank 2 in the case of low water level.

[0051] As shown, Figure 2 , Figure 3As shown, the water tank assembly 100 further comprises a float water inlet valve arranged in the first tank body 1, including a valve body 30, and a float 31 matched with the valve body 30, the float 31 can float to control the water inlet state of the first water tank 1 according to the water level change of the first water tank 1. The float water inlet valve can be a float valve, a ball valve or other control valve which can control the on-off state by the principle of float. The float 31 can be a float or a ball matched with the valve body 30, which can control the working state of the float water inlet valve, for example, when the float 31 is at a high water level, the float water inlet valve is controlled to be closed and the water inlet is stopped; when the float 31 is at a low water level, the float water inlet valve is controlled to be opened and the water inlet is started. In this paper, the float device 3 is mainly described as the float water inlet valve.

[0052] In one example embodiment, as shown in Figure 4 The water tank assembly 100 further comprises a float liquid level switch 3 arranged in the first tank body 1, the float liquid level switch 3 is arranged to be connected with a water inlet valve (not shown, which can be an electric control valve) for supplying water to the first water tank 1. The float liquid level switch includes a switch body 30a, and a float 31 movably arranged in the switch body 30a and capable of floating to trigger a control signal according to the water level change of the first water tank 1, wherein the control signal is used to control the working state of the water inlet valve.

[0053] For example, when the float 31 triggers a control signal reaching a first liquid level (a preset high liquid level), a controller (not shown) connected with the water inlet valve can control the water inlet valve to be closed and stop water supply; when the float 31 triggers a control signal reaching a second liquid level (a preset low liquid level) or when the second liquid level is triggered to reach a first predetermined time, the controller controls the water inlet valve to be opened and the water inlet to be replenished. The specific control liquid level can be set according to the actual situation, which is not limited here.

[0054] As shown in Figure 3 The second water tank 2 includes a tank body 201 and a cover body 202 matched with the tank body 201, wherein the cover body 202 can prevent dust and sundries from falling into the second water tank 2, thereby ensuring the cleanliness of the second water tank 2. The water tank assembly 100 further comprises a water outlet pipe 203 arranged in the cover body 202 and extending into the tank body 201, which is used to take water from the second water tank 2.

[0055] As shown in Figure 2 The water tank assembly 100 further comprises one or more first liquid level detection elements 4 arranged in the first tank body 1, the first liquid level detection elements 4 are arranged to detect the liquid level of the first tank body 1 and monitor the water level of the first water tank 1.

[0056] The water tank assembly 100 further comprises a second liquid level detecting element (not shown) arranged in the second tank 2 for detecting the liquid level of the second tank 2, preventing the second tank 2 from operating with lack of water, which causes the heating device 62 of the human body cleaning system to dry burning and damage.

[0057] As shown in Figures 5-8 , when the water tank assembly 100 of the embodiment of the present application is working, in the initial state, there is no water in the first tank 1 and the second tank 2, the float water inlet valve 3 is opened under the action of the self gravity of the float member 31 or the action of the reset element, and the float water inlet valve 3 starts to fill water to the first tank 1. When the first tank 1 is gradually filled with water, the water flow opens the control valve 21 due to the pressure difference between the second tank 2 and the first tank 1, and the water flows from the first tank 1 to the second tank 2 to fill water to the second tank 2. When the filling of the second tank 2 is completed, the control valve 21 closes the communication hole 20. When the liquid level of the first tank 1 reaches the highest liquid level, the float member 31 controls the float water inlet valve 3 to close, thereby stopping the filling of the entire water tank assembly 100.

[0058] When the water in the first tank 1 is used, the water level decreases, and the control valve 21 remains closed due to the water pressure in the second tank 2, so that the water in the second tank 2 is kept in the second tank 2. The float member 31 of the first tank 1 controls the float water inlet valve 3 to open again to fill water to the first tank 1. When the second tank 2 is used, if there is water in the first tank 1, the first tank 1 will continue to fill water to the second tank 2.

[0059] The water tank assembly 100 of the embodiment of the present application can realize the filling and liquid level control of the two tanks under the action of the pressure difference between the two tanks by arranging the control valve 20 in the first tank 1 and the second tank 2, so as to achieve the purpose of continuous use of water in the two tanks, without using electromagnetic valve body or motor control to realize water filling control, which is low in cost and simple in structure.

[0060] As shown in Figure 11 , Figure 12 , the embodiment of the present application further provides a closestool 200 comprising a closestool body, a water tank assembly 100 or a flushing system as described in any of the above embodiments mounted on the closestool body. The flushing system comprises a closestool flushing system connected with the first tank 1 of the water tank assembly 100, and a human body cleaning system connected with the second tank 2 of the water tank assembly 100.

[0061] Among them, the first tank 1 of the water tank assembly 100 is a flushing water tank, which can be used to supply water to the flushing interface and the siphon interface of the closestool, and provide flushing water. The second tank 2 of the water tank assembly 100 is a cleaning water tank, which can be used to supply water to the cleaning device 61 of the closestool, and provide cleaning water. The water tank assembly 100 can keep the two function systems of the closestool 200 to continuously use water.

[0062] The human body cleaning system comprises a first booster device 61, a heating device 62, and a cleaning device 63. The first booster device 61 boosts the water in the second water tank 2 and delivers the water to the cleaning device 63 to clean the human body. The heating device 62 is used to heat the water in the second water tank 2 and supply the water to the cleaning device 63. The cleaning device 63 is a device used to clean the human body. The specific structure can refer to the prior art, and will not be described here.

[0063] The toilet flushing system is connected with the first water tank 1 of the water tank assembly 100 and the siphon interface and the brush ring interface (not shown) of the toilet 200, and is used to flush the toilet. The toilet flushing system comprises a second booster device 71, a water distribution valve 72, a siphon nozzle 73, and a brush ring nozzle 74. The second booster device 71 boosts the water output by the first water tank 1, supplies the water to the water distribution valve 72, and divides the water into two paths to supply the siphon nozzle 74 and the brush ring nozzle 74, respectively, to flush the toilet body.

[0064] As shown in Figures 12-13 The flushing system comprises the water tank assembly 100 according to any of the above embodiments, the toilet flushing system connected with the first water tank 1 of the water tank assembly 100, and the human body cleaning system connected with the second water tank 2 of the water tank assembly 100.

[0065] When the flushing command is received, the toilet flushing system starts to work, and the first water tank 1 starts to supply water. The water level drops to drive the floating member 31 to drop, so as to control the floating water inlet valve 3 to start to supply water. In one case, if the first water tank 1 is not full, the floating member 31 is in a natural falling state, and the floating water inlet valve 3 is always in an open water inlet state. In another case, if the first water tank 1 has reached a certain water level, the water level of the second water tank 2 drops, and the water in the first water tank 1 flows into the second water tank 2 to supply water to the second water tank 2.

[0066] When the cleaning command is received, the human body cleaning system starts to work, and the water level of the second water tank 2 drops. The water in the first water tank 1 flows into the second water tank 2 to supplement the water in the second water tank 2. After the water level of the first water tank 1 drops, the floating member 31 starts to supply water to the first water tank 1. In one case, if the first water tank 1 is not full, the floating member 31 is in a natural falling state, and the floating water inlet valve 3 is always in an open water inlet state. In another case, if the first water tank 1 has reached a certain water level, the water level of the second water tank 2 drops, and the water in the first water tank 2 flows into the second water tank 2.

[0067] In an exemplary embodiment, the first water tank 1 may be equipped with two first liquid level detection elements 4, one for detecting the high liquid level of the first water tank 1 and the other for detecting the low liquid level of the first water tank 1. A controller (not shown) connected to the flushing system and the first liquid level detection elements 4 determines whether the high liquid level of the first water tank 1 is normal by detecting the liquid level detected by the first liquid level detection element 4, thereby determining whether the first water tank 1 has water (the high liquid level is set at the full water position of the first water tank). The controller determines whether the low liquid level of the first water tank 1 is normal by detecting the liquid level detected by the first liquid level detection element 4, thereby determining whether the second water tank 2 has water (the low liquid level is set at the full water position of the flushing tank). When the first water tank 1 has a high liquid level, the toilet flushing system and the human body washing system are started normally. When the detected low liquid level is normal (greater than or equal to a predetermined first liquid level), the human body washing system can be started. When the low liquid level is abnormal (below the predetermined first liquid level or below the predetermined first liquid level for a predetermined time), the human body washing function is stopped, and a water shortage alarm is triggered to prevent the heating device 62 from dry burning and being damaged. The predetermined first liquid level is higher than or equal to the lowest liquid level of the second water tank 2, thereby ensuring that the second water tank 2 always contains water at that level. Alternatively, a second liquid level detection element 4 can be set up to detect both the high and low liquid levels of the first water tank 1.

[0068] like Figure 9 As shown, in another exemplary embodiment, the first water tank 1 may be equipped with a first liquid level detection element 4 for detecting the liquid level of the first water tank 1, and the second water tank 2 may be equipped with a second liquid level detection element 5 for detecting the liquid level of the second water tank 2. The flushing system can monitor the water levels of the first water tank 1 and the second water tank 2 through the first liquid level detection element 4 and the second liquid level detection element 5. When a flushing command is received, and the liquid level detected by the liquid level detection element 4 is greater than or equal to a first predetermined liquid level (a higher liquid level), the controller connected to the flushing system and the first liquid level detection element 4 can start the toilet flushing system; if the liquid level is lower than the first predetermined liquid level, the toilet flushing system will not be started. In addition, when a cleaning command is received, the flushing system uses the second liquid level detection element 5 of the second water tank 2 to determine whether the liquid level of the second water tank 2 is normal, and to determine whether water has entered the second water tank 2. When the liquid level is normal (the liquid level is greater than or equal to the second predetermined liquid level), the controller connected to the flushing system and the second liquid level detection element 5 starts the human body cleaning system. Specifically, the first increasing device 61 draws water from the second water tank 2 to supply the heating device 62 and the cleaning device 63 connected to the outlet of the heating device 62, and starts the heating device 62 and the cleaning device 63 to achieve the cleaning function; when the detected liquid level is abnormal (liquid level is less than the second predetermined liquid level or less than the second predetermined liquid level for a predetermined time), the controller controls the human body cleaning system to stop operating and can perform a water shortage alarm to prevent the heating device 62 from burning dry and being damaged.

[0069] The two water tanks of the flushing assembly 100 can respectively supply water for the flushing water channel of the flushing system and the toilet flushing system, and can match the water supplement of different water conditions of the two toilet flushing systems, reduce the functional components, reduce the complexity of connection and control, and reduce the cost and save the space.
