Description

Technical Field

[0001] The present invention relates to bathroom technology, in particular to a water tank assembly, a flushing system, a toilet and a control method thereof. Background Art

[0002] The control of the water circuit of the smart toilet is usually point-to-point and line-to-line. After the water circuit is separated from the angle valve end, the smart toilet flushing water circuit and the smart toilet lid cleaning water circuit are used separately. There are corresponding advantages to controlling the water circuit independently, such as simple connection logic and no need to consider other related application relationships; but the disadvantage is that it will cause more connecting pipes between modules and the number of connecting parts, resulting in a larger space requirement for installation.

[0003] In addition, independent control of the water circuit will also cause the related functional devices to perform a single function, which will not effectively improve the utilization rate of the device and will also cause a waste of resources on the control board. For example, for the water inlet module, the functions of controlling the water inlet of the smart toilet lid cleaning water circuit and controlling the smart toilet flushing system are the same, and under normal circumstances, the functional applications of the two are staggered, and the two functions will not be used at the same time. However, after each is independent, the functional tasks they perform are very single, and two sets of water inlet modules are required to support a water circuit system, resulting in a waste of resources.

[0030] like Figure 1-Figure 7 As shown, the embodiment of the present application provides a toilet 200 and a water tank assembly 100 (see Figure 1 The toilet 200 may be a sitting type or a squatting type, and the water tank assembly 100 provides water for the toilet 200.

[0031] like Figure 1 , Figure 2As shown, the toilet 200 of the embodiment of the present application includes a toilet body and a water tank assembly 100 installed on the toilet body. The water tank assembly 100 includes a first water tank 1, a second water tank 2, a floating liquid level switch 3 and a water inlet linkage assembly 4. The second water tank 2 is provided with an overflow port 20 connected to the first water tank 1, so that the water in the second water tank 2 can overflow from the overflow port 20 into the first water tank 1. The floating liquid level switch 3 is provided in the second water tank 2, and is configured to be connected to the water inlet valve 5 that supplies water to the second water tank 2, and the floating liquid level switch 3 includes a first floating member 31 that can float with the change of the water level of the second water tank 2 to trigger a control signal, and the control signal is used to control the working state of the water inlet valve 5. The water tank assembly 100 also includes a controller 8 connected to the floating liquid level switch 3 and the water inlet valve 5, and the controller 8 is configured to control the water inlet to be opened or closed according to the control signal.

[0032] The water tank assembly 100 of the embodiment of the present application is provided with two water tanks 1 and 2, and the first water tank 1 is filled with water by overflowing the second water tank 2, so that the two water tanks can use the same water inlet valve 5 to fill with water, and there is no need to set up a separate water inlet component, which reduces the cost and the complexity of connection and control, and saves space. In addition, the water tank assembly 100 detects the liquid level of the second water tank 2 by setting a floating liquid level switch 3 and associates it with the working state of the water inlet valve 5, thereby realizing normal water use of the water tank assembly 100.

[0033] like Figure 2 As shown, the controller 8 is configured to perform the following operations when receiving a water use command from the second water tank 2: S1, when the water level of the second water tank 2 drops, the first floating member 31 is driven to drop and trigger a control signal below the first liquid level, and when the first floating member 31 is triggered to reach the second liquid level (refer to Figure 4 When the water level of the second water tank 2 rises, the first floating member 31 is driven to rise and trigger the water level to reach the first liquid level (reference water level position of the second water tank 2 in the water tank 2). Figure 3 When a control signal (the water level position of the second water tank 2) is received, the controller 8 controls the water inlet valve 5 to close.

[0034] The water tank assembly 100 of the embodiment of the present application detects the liquid level of the second water tank 2 by setting a floating liquid level switch 3, and at the same time associates the working state of the water inlet valve 5 with the high liquid level (first liquid level) and low liquid level (second liquid level) of the second water tank 2, or associates the high liquid level (first liquid level) with the water use time, so that the second water tank 2 can be replenished with water or stopped replenishing with water in time, thereby ensuring normal water use in the second water tank 2 and preventing water shortage.

[0035] like Figure 1 , Figure 5As shown, the water inlet linkage assembly 4 of the embodiment of the present application is arranged in the first water tank 1, and is configured to float following the water level change of the first water tank 1, and can cooperate and link with the first floating member 31 to enable the first floating member 31 to trigger a control signal.

[0036] The water tank assembly 100 of the embodiment of the present application is capable of providing feedback and controlling the water level of the first water tank 1 by setting a water inlet linkage assembly 4 that cooperates with the floating liquid level switch 3 on the first water tank 1, so that the floating liquid level switch 3 indirectly controls the water inlet situation of the first water tank 1. Therefore, the water tank assembly 100 not only realizes the use of the same water inlet valve 5 for water inlet into two water tanks, but also realizes continuous water use for the first water tank 1 and the second water tank 2, reduces the use of components such as liquid level sensors, does not need to use an electromagnetic valve body or motor control to realize water inlet control, saves costs, and ensures reliable control.

[0037] The floating liquid level switch 3 in this embodiment includes a main body 30 extending to the bottom of the inner cavity of the second water tank 2, and the first floating member 31 is a floating ring, which is sleeved on the outer wall of the main body 30 and can move up and down on the main body 30 according to the change of water level. The floating liquid level switch 3 in this embodiment of the application adopts a Hall switch, and the first float 31 is driven to approach and move away from the switch element by the rise and fall of the water flow to trigger the control signal.

[0038] The water inlet linkage assembly 4 of the embodiment of the present application includes a first working state (see reference 4) that cooperates with the first floating member 31 to cause the first floating member 31 to trigger a control signal. Figure 6 ) and release the second working state of the first floating member 31 (refer to Figure 7 ).

[0039] In the embodiment of the present application, the water inlet linkage assembly 4 switches between the first working state and the second working state under the interaction of its own gravity and the change of the water level of the first water tank 1. For example, when the water level drops, the water inlet linkage assembly 4 drops under the action of its own gravity, so that the water inlet linkage assembly 4 drives the first floating member 31 to open the buoyant water inlet valve 3 to replenish the water inlet to the first water tank 2; when the water level of the first water tank 1 rises, the water inlet linkage assembly 4 is pushed up to release the action on the first floating member 31, and the buoyant water inlet valve 3 can be in a closed state or in an open state to replenish the water in the second water tank 2.

[0040] like Figure 5 As shown, the water inlet linkage assembly 4 includes a second floating member 41 and a connecting rod 42 that can float up and down following the change in the water level of the second water tank 2. One end of the connecting rod 42 cooperates with the first floating member 31, and the other end is connected to the second floating member 41. In the first working state, the connecting rod 42 presses against the first floating member 31 (see Figure 6), driving the buoyancy liquid level switch 3 to trigger a control signal to open the water inlet valve 5 to replenish water; in the second working state, the connecting rod 42 releases the pressure on the first floating member 41 (refer to Figure 7 ), no force is exerted on the buoyancy liquid level switch 3.

[0041] The second floating member 41 in this embodiment is provided with a mounting groove (not shown), and the connecting rod 42 is inserted into the mounting groove and installed in cooperation with the second floating member 41. Of course, the second floating member 41 and the connecting rod 42 can also be formed in one piece, which is not limited here. The second floating member 41 in this embodiment adopts a buoy, and of course it can also be a floating ball, which is not limited here.

[0042] like Figure 6 As shown, when the water level drops, the water inlet linkage assembly 4 drops under the action of its own gravity, so that the water inlet linkage assembly 4 drives the first floating member 31 to trigger the control signal to open the water inlet valve 5, so as to replenish water into the first water tank 2. Figure 7 As shown, when the water level of the first water tank 1 rises, the water inlet linkage assembly 4 is pushed up, and the water inlet linkage assembly 4 releases the force on the first floating member 31. At this time, the first water tank 1 is in a full load state, the water inlet valve 5 can be in a closed state, or it can be in an open state and replenish water to the second water tank 2, and the water inlet linkage assembly 4 does not interfere with the operation of the floating liquid level switch 2.

[0043] In another exemplary embodiment, the water tank assembly 100 further includes a reset element (not shown) that provides a reset force for the water linkage assembly 4, and the water inlet linkage assembly 4 switches between the first working state and the second working state under the interaction of the reset element and the water level change of the first water tank 1. The reset element may be a reset spring or the like.

[0044] like Figure 1 , Figure 2 As shown, the second water tank 2 of this embodiment is suspended on the first water tank 1 and is located outside the first water tank 1. The second water tank is provided with a slot (not numbered), which is inserted from the notch of the first water tank 1 to the side wall of the first water tank 1 to suspend the second water tank 2. Of course, the second water tank 2 can also be installed with the first water tank 1 in other ways, and the second water tank 2 can also be set in the first water tank 1, which is set according to actual conditions and is not limited here.

[0045] like Figure 2 As shown, the second water tank 2 is provided with a guide channel 21 extending into the inner cavity of the first water tank 1 and guiding the water flow along the side wall of the first water tank 1 into the first water tank 1, and the water inlet end of the guide channel 21 is connected with the overflow port 20. The water flow entering the first water tank 2 is guided to the side wall of the first water tank 1 through the guide channel 21, which can prevent water splashing on the one hand and reduce water inlet noise on the other hand.

[0046] like Figure 1As shown, the first water tank 1 is provided with a guide portion 10, and the second floating member 41 is installed in cooperation with the guide portion 10 and can move up and down under the guidance of the guide portion 10 when the water level changes. Figure 2 As shown, the first water tank 1 includes a first tank body 101 and a first top cover 102. The first top cover 102 is provided with guide ribs 11 extending toward the bottom of the inner cavity of the first water tank 1 (see Figure 1 ), the space between the guide rib 11 and the outer side wall of the guide channel 21 forms a guide portion 10.

[0047] like Figure 2 As shown, the second water tank 2 includes a second tank body 201 and a second top cover 202 that cooperates with the second water tank body 201. The floating liquid level switch 3 is installed on the second top cover 202.

[0048] like Figure 6 , Figure 7 As shown, the controller 8 of the water tank assembly 100 of the embodiment of the present application is also configured to perform the following operations when the first water tank 1 uses water: S3, when the water level of the first water tank 1 drops, the water inlet linkage assembly 4 is driven to drop and act on the first floating member 31, and when the water level is lower than the first liquid level control signal, the controller 8 controls the water inlet valve 5 to open; S4. When the water level in the first water tank 1 rises, the water inlet linkage assembly 4 rises and releases the action on the first floating member 31. When the water level in the second water tank 2 rises and drives the first floating member 31 to trigger a control signal reaching the first liquid level, the controller 8 controls the water inlet valve 5 to close.

[0049] The water tank assembly 100 of this embodiment controls the position of the first floating member 31 by setting the water inlet linkage assembly 4 to be linked with the first floating member 31 , thereby achieving control of the working state of the water inlet valve 4 .

[0050] In the embodiment of the present application, whether the first water tank 1 and the second water tank 2 use water can be determined by a water use command triggered by the user. The water use command can be a physical switch or a voice-controlled switch.

[0051] 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 water tank 1 and the second water tank 2. When the floating liquid level switch 3 is at a low position under the gravity of the first floating member 31, the controller 8 controls the water inlet valve 5 to open to replenish water in the second water tank 2. Since there is no water in the first water tank 1, the water inlet linkage assembly 4 presses the first floating member 31 under the action of its own gravity. Even if the water level of the second water tank 2 rises, the first floating member 31 cannot rise under the drive of the water flow. The controller 8 cannot receive the control signal to reach the first liquid level, and the water inlet valve 5 is kept to keep water flowing.

[0052] When the water in the second water tank 2 reaches the overflow level, the water flows from the overflow port 20 into the first water tank 1 to replenish the first water tank 1. When the water level in the first water tank 1 continues to rise to a level that can drive the water inlet linkage assembly 4 to move upward until the water inlet linkage assembly 4 releases the pressure on the first floating member 31, the first floating member 31 floats under the action of the water flow, and no force is applied to the first floating member 31, so the first floating member 31 can float freely. When the second water tank 2 rises to the first liquid level, the controller 8 receives the control signal of reaching the first liquid level, and closes the water inlet valve 5, thereby stopping the replenishment of the entire water tank assembly 100.

[0053] When the first water tank 1 is used, the water level of the first water tank 1 drops. At this time, regardless of whether the water in the first water tank 2 is used, the water inlet linkage assembly 4 presses the first floating member 31 under the action of its own weight, triggering a signal of a level lower than the first liquid level, so that the water inlet valve 8 opens to replenish water for the first water tank 1. Similarly, when the water inlet valve 8 is completed, the water inlet valve 8 is closed.

[0054] When the second water tank 2 uses water, the water level of the second water tank 2 drops. When the water level drops less, no water replenishment is performed. When the water level drops to the bottom water level (second liquid level position) or is lower than the first liquid level for a first predetermined time (e.g., 5-10 seconds), the water replenishment control signal is triggered, and the controller 8 controls the water inlet valve 5 to open for water replenishment. After the water inlet valve 5 is opened for water replenishment, if the water level continues to be lower than the second liquid level, it is necessary to stop using water in the second water tank 2 to prevent the second water tank 2 from drying out due to lack of water, which may cause damage to the device. Since the first water tank 1 is full of water, the water inlet linkage assembly 4 releases the pressure on the first floating member 31, so that the first floating member 31 can float freely to replenish the second water tank 2 with water.

[0055] The water tank assembly 100 of the embodiment of the present application utilizes the water level change of the water tank and the water inlet linkage assembly 4 to control the first floating member 31 of the floating liquid level switch 3 to realize the function of replenishing water to the two water tanks, without using a solenoid valve body or a motor, and has a simple connection and low cost. The design of the water inlet linkage assembly 4 of the embodiment of the present application can not only realize the action of continuously circulating water replenishment to the two water tanks.

[0056] like Figure 8 As shown, the embodiment of the present application also provides a toilet 200 including a toilet body and a water tank assembly 100 as described in any of the above embodiments installed on the toilet body. The first water tank 1 of the water tank assembly 100 is a flushing water tank, which can be used to supply water to the siphon interface and flushing interface of the toilet to provide flushing water. The second water tank 2 of the water tank assembly 100 is a cleaning water tank, which can be used to supply water to the cleaning device 63 of the toilet to provide cleaning water. The water tank assembly 100 can maintain the water for the flushing working mode of the two continuous waterways of the toilet 200.

[0057] The embodiment of the present application also provides a flushing system, including the water tank assembly 100, the toilet flushing system A and the human body cleaning system B as described in any of the above embodiments.

[0058] The human body washing system A is connected to the second water tank 2 of the water tank assembly 100, and includes a first pressurizing device 61, a heating device 62, and a cleaning device 63. The first pressurizing device 61 pressurizes the water in the second water tank 2 and then delivers it to the cleaning device 63 for washing the human body, and the heating device 62 is used to heat the water in the second water tank 2 and then supply it to the cleaning device 63. The cleaning device 63 is a device for washing the human body, and the specific structure can refer to the prior art, which is not repeated here.

[0059] When the controller 8 receives the cleaning command, when the first floating member 31 triggers a control signal that the liquid level is lower than the second liquid level or when the liquid level is lower than the second liquid level for a second predetermined time, the human body cleaning system A is controlled to stop running. The water level at this time indicates that the replenishment amount is insufficient. Stopping the use of the second water tank 2 can avoid a poor user experience, and more importantly, prevent dry burning caused by lack of water in the second water tank.
