Description

Technical Field

[0001] This article relates to bathroom technology, in particular to cistern components, flushing systems, toilets and methods for controlling them. 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. The corresponding advantage of controlling the water circuit independently is that the connection logic is simple and there is no need to consider other related application relationships; the disadvantage is that it will cause more connecting pipes between modules and the number of connecting parts is also large, resulting in a larger space requirement for installation.

[0003] 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 being independent, the functional tasks they perform are very single, and two sets of water inlet modules are needed to support a water circuit system, resulting in a waste of resources.

[0029] 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 or squatting toilet, and the water tank assembly 100 provides water for the toilet 200.

[0030] 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.

[0031] The second water tank 2 is provided with an overflow port 20 communicating with 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 arranged to be connected to the water inlet valve 5 supplying 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 inlet linkage assembly 4 is provided in the first water tank 1, and is arranged to float with the change of the water level of the first water tank 1, and cooperates with the first floating member 31 to make the first floating member 31 trigger the control signal.

[0032] The first water tank 1 of the water tank assembly 100 of the embodiment of the present application is filled with water by overflowing the second water tank 2, thereby reducing the use of water inlet valves and reducing the complexity of connection and control. Moreover, the water tank assembly 100 of the embodiment of the present application is provided with a water inlet linkage assembly 4 in the first water tank 1 that cooperates with the floating liquid level switch 3, so that the water level inlet of the first water tank 1 can be fed back and controlled, so that the floating water inlet valve 3 indirectly controls the water inlet of the first water tank 1, and realizes the control of the water inlet and water level of the first water tank 1 and the second water tank 2, so as to achieve the purpose of continuous water use, reduce the use of components such as liquid level sensors, and do not need to use electromagnetic valve bodies or motor control to realize water inlet control, thereby saving costs and ensuring reliable control.

[0033] like Figure 3 As shown, 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 of the application embodiment 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.

[0034] 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 ).

[0035] 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 water level change of the first water tank 1.

[0036] like Figure 4As 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 buoyancy water inlet valve 3, and replenish water into the first water tank 2. Figure 5 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 3.

[0037] 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.

[0038] like Figure 3 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 of the water level of the first water tank 1. 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 water inlet valve 2 to open and replenish water; in the second working state, the connecting rod 42 releases the first floating member 41 (refer to Figure 7 ), no force is exerted on the buoyancy inlet valve 2.

[0039] 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 assembled 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.

[0040] 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. As shown in the figure, the second water tank 2 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 equipped 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.

[0041] like Figure 2As 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.

[0042] like Figure 1 As shown, the first water tank 1 is provided with a guide portion 10, and the second floating member 41 is assembled 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 a guide rib 11 extending toward the bottom of the inner cavity of the first water tank 1 . The space between the guide rib 11 and the outer wall of the guide channel 21 forms a guide portion 10 .

[0043] 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 and extends into the second water tank body 201 .

[0044] The first water tank 1 and the second water tank 2 of the water tank assembly 100 of the present embodiment are both provided with covers, which can prevent dust and the like from falling into the tanks, thereby keeping the tanks clean and preventing water from overflowing.

[0045] like Figure 2 As shown, the water tank assembly 100 of the embodiment of the present application further includes a controller 8 connected to the floating liquid level switch 3 and the water inlet valve 5. When the controller 8 receives a water use command of the first water tank 1, the controller 8 is configured to perform the following operations: S1. When the water level of the first water tank 1 drops, the first floating member 31 sinks under the action of the water inlet linkage assembly 4 and triggers a control signal below the first liquid level. The controller 8 controls the water inlet valve 5 to open (refer to Figure 4 ); S2. When the water level of the first water tank 1 rises, the first floating member 31 is separated from the water inlet linkage assembly 4, and when the water level of the second water tank 2 rises and drives the first floating member 31 to rise, triggering the control signal reaching the first liquid level, the controller 8 controls the water inlet valve 5 to close. Generally, when the first floating member 31 rises to the upper limit, the control signal reaching the first liquid level is triggered, thereby controlling the electronic water inlet valve to close (refer to Figure 5 ).

[0046] In this embodiment, the position of the first floating member 31 is controlled by the linkage between the water inlet linkage assembly 4 and the first floating member 31 , thereby controlling the working state of the water inlet valve 5 and achieving continuous water use of the first water tank 1 .

[0047] When the controller 8 receives the water use command of the second water tank 2, the controller 8 is configured to further perform the following operations: S3, 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 of being lower than the first liquid level, and when the first floating member 31 triggers a control signal of reaching the second liquid level or when the time of being lower than the first liquid level reaches a first predetermined time, the controller 8 controls the water inlet valve 5 to open; S4. When the water level in the second water tank 2 rises, driving the first floating member 31 to rise and triggering a control signal to reach the first liquid level, the controller 8 controls the water inlet valve 5 to close; the first liquid level is higher than the second liquid level.

[0048] The water tank assembly 100 of the embodiment of the present application sets the relationship between the first liquid level and the second liquid level or time, so that when the water level of the second water tank 2 is too low after water is used, it is necessary to control the water inlet valve 5 to inlet water. The water use commands for the first water tank 1 and the second water tank 2 may be commands for users to trigger a physical switch or a voice-controlled switch.

[0049] 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, the floating liquid level switch 3 is at a low position under the gravity of the first floating member 31, and 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 2, the water inlet linkage assembly 4 presses the first floating member 31 under the action of its own gravity, and even if the water level of the second water tank 2 rises, the first floating member 31 cannot rise driven by the water flow, and the controller 8 cannot receive the control signal to reach the first liquid level, so the water inlet valve 5 is kept to keep water flowing.

[0050] 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 2 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 does not exert force on the first floating member 31. Then, the first floating member 31 rises to the first liquid level in the second water tank 2, and the controller 8 receives the control signal of reaching the first liquid level, and then closes the water inlet valve 5, thereby stopping the replenishment of the entire water tank assembly 100.

[0051] 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 its own weight, triggering a signal of a level lower than the first liquid level, so that the water inlet valve 5 opens to replenish water in the first water tank 1. When the first water tank 1 is replenished with water, the water inlet valve 5 may be closed or opened.

[0052] 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 the time below the first liquid level position reaches a first predetermined time (which can be 5-10 seconds, specifically depending on the size of the water tank and the water inlet design), the water replenishment control signal is triggered, and the controller 8 controls the water inlet valve 5 to open for water replenishment. When the water level continues to be lower than the second liquid level after the water inlet valve 5 is opened for water replenishment, it is necessary to stop the use of 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.

[0053] 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 achieve continuous water supply to the two water tanks without the need for 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 achieve continuous circulation of water supply to the two water tanks. Figure 2 , Figure 7 As shown, the toilet 200 further includes a water inlet valve 5 connected to the second water tank 2 and supplying water to the second water tank 2. The water inlet valve 5 works by receiving a control signal from the floating liquid level switch 3. The toilet 200 further includes a cleaning water path A connected to the second water tank 2 and a flushing water path B connected to the first water tank 1.

[0054] The clean water circuit A includes a first increasing device 61, a heating device 62, and a cleaning device 63. The first increasing 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. 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. The specific structure can refer to the prior art and will not be repeated here.

[0055] The controller 8 of the water tank assembly 100 of this embodiment is also connected to the human body cleaning system A and the toilet flushing system B, and is configured to perform the following operations when receiving a water use command from the second water tank 2: S5. When the first floating member 31 triggers a control signal lower than the second liquid level and when the second predetermined time is reached, the controller 8 controls the human body washing system A 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.

[0056] The flushing water path B includes a second increasing device 71, a water path distribution valve 72, a siphon nozzle 73 and a brush ring nozzle 74. The second increasing device 6 increases the water output from the first water tank 2 and supplies it to the water path distribution valve 7 to divide the water into two paths and supply them to the siphon nozzle 73 and the brush ring nozzle 74 respectively to flush the toilet.

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

[0058] The two water tanks of the flushing assembly 100 of the embodiment of the present application can supply water to the cleaning water circuit A and the flushing water circuit B of the flushing system respectively, and can match the water replenishment of the two flushing water circuits in different water use conditions, thereby reducing functional components and reducing the complexity of the connection.

[0059] like Figure 8 As shown, an embodiment of the present application further provides a toilet 200 including a toilet body, and a water tank assembly 100 or a flushing system as described in any of the above embodiments installed on the toilet body.

[0060] 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 brush ring interface and the siphon interface of the toilet to provide flushing water.
