Description

Technical Field

[0001] The present invention relates to bathroom technology, in particular to a cistern assembly, a flushing system and a toilet. 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 cover human body cleaning system are used separately. There are corresponding advantages to controlling the water circuit alone, 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 devices 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 human body cleaning system of the smart toilet cover and controlling the flushing system of the smart toilet 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 simple, and two sets of water inlet modules are required to support a water circuit system, resulting in a waste of resources.

[0027] like Figure 1-Figure 10 As shown, an embodiment of the present application provides a water tank assembly 100, which can be used in a toilet and supply water to the toilet, wherein the toilet can be a sitting toilet, a squatting toilet, etc.

[0028] like Figure 1-Figure 4 As shown, the water tank assembly 100 of the embodiment of the present application includes a first water tank 1, a second water tank 2, a buoyancy water inlet valve 3 and a water inlet linkage assembly 4.

[0029] like Figure 3 As shown, 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 to the first water tank 1. Figure 2 , Figure 4 As shown, the buoyancy inlet valve 3 is installed in cooperation with the second water tank 2 to supply water to the second water tank 2. The buoyancy inlet valve 3 includes a first floating member 31 that can float with the change of the water level of the second water tank 2 to control the on and off of the buoyancy inlet valve 3. Figure 2 , Figure 3 As shown, the water inlet linkage assembly 4 is arranged in the first water tank 1 and is installed in conjunction with the first floating member 31 , and is configured to float with the water level change of the first water tank 1 to cooperate with the first floating member 31 to control the working state of the buoyancy water inlet valve 3 .

[0030] The second water tank 2 of the water tank assembly 100 of the embodiment of the present application is filled with water by setting a buoyancy water inlet valve 3, and the first water tank 1 is filled with water by overflow of the second water tank 2. The second water tank 2 does not need to use a separate water inlet component, thereby reducing the complexity of connection and control, reducing costs and saving space.

[0031] Moreover, the water tank assembly 100 of the embodiment of the present application is capable of providing feedback and controlling the water level inflow of the first water tank 1 by disposing a water inlet linkage assembly 4 on the first water tank 1 that cooperates with the buoyancy inlet valve 3 that supplies water to the second water tank 2, so that the buoyancy inlet valve 3 indirectly controls the water inflow situation of the first water tank 1, thereby achieving continuous water use of the first water tank 1 and the second water tank 2, without the need to use an electromagnetic valve body or motor control to achieve water inflow control, with low cost and simple structure.

[0032] like Figure 4 As shown, the buoyancy inlet valve 3 in this embodiment is a control valve such as a float valve or a float ball valve that uses the floating principle of a floating member to achieve on-off control. For example, when the first float member 31 is at a high water level, the buoyancy inlet valve 3 is controlled to be closed; when the first float member 31 is at a low water level, the buoyancy inlet valve 3 is controlled to be opened. The buoyancy inlet valve 3 includes a valve body 30 and a first float member 31 that can be movably mounted with the valve body 30, wherein the first float member 31 can be a float or a float ball. The valve body 30 can be arranged in the second water tank 2 or outside the second water tank 2, which is not limited here.

[0033] like Figure 2 As shown, the buoyancy inlet valve 3 of this embodiment is arranged in the second water tank 2, and the bottom of the second water tank 2 is provided with a water inlet 203 which is installed in cooperation with the buoyancy inlet valve 3. The arrangement of the water inlet 203 can facilitate the flexible installation of the water tank assembly 100 and save space. Of course, the buoyancy inlet valve 3 can also be partially arranged outside the second water tank 2, which is not limited here; the water inlet 203 can also be arranged at other positions of the second water tank 2, which is not limited here.

[0034] The water inlet linkage assembly 4 of the embodiment of the present application includes a first working state (see FIG. 1 ) which cooperates with the first floating member 31 to open the buoyancy water inlet valve 3. Figure 7 ) and release the second working state of the buoyancy inlet valve 3 (reference Fig. 9 ).

[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 change of the water level of the first water tank 1. 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 water into the first water tank 1; 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 action on the first floating member 31. At this time, the buoyant water inlet valve 3 can be in a closed state, or it can be in an open state to replenish water into the second water tank 2.

[0036] 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.

[0037] like Figure 3 , Figure 4 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. The connecting rod 42 in this embodiment includes a horizontal rod part and a vertical rod part. The horizontal rod part is installed in cooperation with the second floating member 31, and the vertical rod part is connected to the second floating member 41.

[0038] In the first working state, the connecting rod 42 presses against the first floating member 31 (see Figure 7 ), driving the buoyancy water inlet valve 3 to open and replenish water; in the second working state, the connecting rod 42 releases the first floating member 41 (reference Figure 8 ) does not exert force on the buoyancy inlet valve 3.

[0039] like Figure 4 As shown, the second floating member 41 in this embodiment is provided with a mounting groove 410, and the connecting rod 42 is inserted into the mounting groove 410 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.

[0040] like Figure 1 As shown, in this embodiment, the first water tank 1 is larger than the second water tank 2, and the second water tank 2 is an independent water tank, which is accommodated in the first water tank 1, thereby saving the volume of the water tank assembly 100 as a whole, reducing the installation space, and ensuring the cleanliness of the second water tank 2. Of course, the second water tank 2 and the first water tank 1 can also be installed separately, the first water tank 1 and the second water tank 2 can also be the same size, or the first water tank 1 is smaller than the second water tank 2, which is not limited here.

[0041] like Figure 2 , Figure 3 , Figure 5 As shown, the first water tank 1 is provided with a receiving chamber 11 and a water storage chamber 12 , the second water tank 2 is received in the receiving chamber 11 , and the overflow port 20 of the second water tank 2 is communicated with the water storage chamber 12 .

[0042] The second water tank 2 includes a main body 21 and a protruding body 22 extending into the water holding chamber 12, and the first floating member 31 is at least partially disposed in the protruding body 22. The water inlet linkage assembly 4 is installed outside the protruding body 22 in a floating manner, and the connecting rod 42 partially extends into the protruding body 22, and partially extends out of the protruding body 22 and is connected to the second floating member 41. The accommodating chamber 11 and the upper part of the water holding chamber 12 are connected so that the protruding body 22 can extend into the water holding chamber 12. The second water tank 2 can facilitate the installation of the water inlet linkage assembly 4 and the first floating member 31 by providing the protruding body 22, save space, and reduce the complexity of installation.

[0043] like Figure 3 , Figure 5 As shown, the protruding box body 22 is provided with a first guide portion 221 and a second guide portion 222 on one side of the water chamber 12, and the first guide portion 221 and the second guide portion 222 are arranged up and down. The protruding portion of the connecting rod 42 is installed in cooperation with the first guide portion 221, and the second floating member 41 is installed in cooperation with the second guide portion 222. Under the action of the water flow, the second floating member 41 and the connecting rod 42 can be lifted and lowered under the guidance of the first guide portion 221 and the second guide portion 222. In this embodiment, the first guide portion 221 and the second guide portion 222 are both cylindrical with upper and lower openings.

[0044] like Figure 3 As shown, the buoyancy water inlet valve 3 also includes a accommodating cylinder 32 for accommodating the first floating member 31, and the bottom wall of the accommodating cylinder 32 is provided with a limiting portion 223. The first floating member 31 is movably connected to the limiting portion 223, and the limiting portion 223 is used to control the first floating member 31 to rise and fall in the vertical direction, and to control the rising height of the first floating member 31.

[0045] like Figure 4 , Figure 5 As shown, the second water tank 2 includes a tank body 201 and a cover body 202 that fits the tank body 201. The water tank assembly 100 also includes a liquid level detection element 2021 and a water outlet pipe 2022 that are arranged on the cover body 202 and extend into the tank body 201. The liquid level detection element 2021 is configured to detect the liquid level of the tank body 201, thereby monitoring the water level of the second water tank 2 to prevent the following human body washing system from running without water. The second water tank 2 of this embodiment can prevent dust and debris from falling into the second water tank 2 by providing the cover body 202, thereby ensuring the cleanliness of the second water tank 2.

[0046] like Figure 6 As shown, the water tank assembly 100 also includes a filter device 23 disposed at the water outlet position of the second water tank 2, which is used to filter the water of the second water tank 2 and then output it, thereby improving the cleanliness of the water output from the second water tank 2. The water outlet pipe 2022 extends into the filter device 23 to obtain the filtered water, thereby improving the cleanliness of the water used in the second water tank 2. The filter device 23 in this embodiment adopts a nylon filter screen, and of course the filter device can also adopt an internal or external filter, which is not limited here. By designing the second water tank 2 as a split type, it is convenient to replace or clean the filter device 23.

[0047] like Figure 7-10 As shown, 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, and the buoyancy water inlet valve 3 is opened under the action of the first floating member 31's own gravity or the action of the reset element, and the buoyancy water inlet valve 3 begins to take in water to replenish the second water tank 2. At this time, the water inlet linkage assembly 4 presses the first floating member 31 under the action of its own gravity or the reset element to drive the first floating member 31 to keep the buoyancy water inlet valve 3 open. When the water in the second water tank 2 reaches the overflow water level, the water flows from the overflow port 20 into the water holding chamber 11 of the first water tank 1 to replenish the first water tank 1. When the water level continues to rise to be able to 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. At this time, if the second water tank 2 is full of water, the first floating member 31 floats up under the action of the water flow, closing the buoyancy water inlet valve 3, and then stopping the water replenishment of the entire water tank assembly 100; if the second water tank 2 is not full of water, the buoyancy water inlet valve 3 continues to replenish the second water tank 2 with water.

[0048] When the water in the first water tank 1 is used, the water level drops. At this time, regardless of whether the water in the second water tank 2 is used or not, the water inlet linkage assembly 4 presses the first floating member 31 under the action of its own weight to drive the first floating member 31 to open the buoyancy water inlet valve 3, so that the water inlet valve 3 can always replenish water for the first water tank 1.

[0049] When the first water tank 1 is full of water, but the water in the second water tank 2 is used, the water level drops. At this time, 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, and the second water tank 2 can be replenished or stopped.

[0050] The water tank assembly 100 of the embodiment of the present application utilizes the water level changes in the water tank and the water inlet linkage assembly 4 to control the opening and closing of the buoyancy water inlet valve 3, thereby realizing water replenishment and water level control of the two water tanks, thereby achieving the purpose of continuous water use. It does not require the use of an electromagnetic valve body or motor control to achieve water inlet control, and has low cost and simple structure.

[0051] The design of the water inlet linkage assembly 4 of the embodiment of the present application can not only realize the water replenishment of the two water tanks, but also can repeat the action of continuous water replenishment.

[0052] like Figure 11-Figure 15 As shown, the embodiment of the present application also provides a flushing system, including the water tank assembly 100 as described in any of the above embodiments, a toilet flushing system ( Fig.13 ) and human body cleaning system ( Fig.14 ).

[0053] like Fig.13 As shown, the human body washing system 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.

[0054] The toilet flushing system connects 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 300, and is used to flush the toilet. The toilet flushing system includes a second booster 71, a water channel distribution valve 72, a siphon nozzle 73, and a brush ring nozzle 74. The second booster 71 increases the water output from the first water tank 1, supplies it to the water channel distribution valve 72, divides the water into two paths, and supplies them to the siphon nozzle 73 and the brush ring nozzle 74 respectively, so as to flush the toilet 200.

[0055] The two water tanks of the flushing assembly 100 of the embodiment of the present application can supply water to the toilet flushing system of the human body cleaning system respectively, and can match the water replenishment of the two systems under different water usage conditions, reducing functional components, reducing the complexity of connection and control, and reducing costs and saving space.

[0056] like Fig.10 , Fig.11 As shown, an embodiment of the present application further provides a toilet 200 including a toilet body, a water tank assembly 100 as described in any of the above embodiments installed on the toilet body, or a flushing system as described in any of the above embodiments.

[0057] 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. 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 continuous water use for the two systems of the toilet 200. The flushing system in this embodiment is integrated on the mounting base and is installed in conjunction with the water tank assembly 100.

[0058] When the flushing system of the embodiment of the present application is working, the buoyancy water inlet valve 3 is opened, and tap water enters the second water tank 2 of the water tank assembly 100, and the interior of the second water tank 2 is gradually filled with water, and flows into the first water tank 1 through the overflow port 20. When the first water tank 1 is not full, the second floating member 41 and the connecting rod 42 are in a natural falling state, and the first floating member 31 of the floating water inlet valve 3 is always in the state of opening the floating water inlet valve 3 until the two water tanks are filled with water.

[0059] When the controller of the flushing system receives a cleaning command (for example, the user triggers the cleaning button), the first increasing device 61 starts working to pump water, the water storage in the second water tank 2 will decrease and the water level will decrease, and the first floating member 31 of the floating water inlet valve 3 will drop, opening the floating water inlet valve 3. At this time, tap water enters the second water tank 2, and the inside of the second water tank 2 is gradually filled with water. When the second water tank 2 is full of water, the water overflows into the first water tank 1. The first case: if the first water tank 1 is not full, at this time, the second floating member 41 and the connecting rod 42 are in a natural falling state, the first floating member 31 is pressed down, and the floating water inlet valve 3 is always in an open water inlet state. The second case: if the first water tank 1 has reached a certain water level, the second water tank 2 cannot be filled with water, the second floating member 41 begins to float up due to the buoyancy, pushing the connecting rod 42 to move upward, at this time the connecting rod 42 is separated from the first floating member 31, the first floating member 31 floats up, and the floating water inlet valve 3 continues to replenish water for the second water tank 2.

[0060] The controller of the flushing system controls the liquid level detection element 2021 to determine whether the liquid level of the second water tank 2 is normal, whether there is water in the second water tank 2, and if the liquid level is normal (the liquid level is greater than or equal to the predetermined liquid level), the controller controls the first increasing device 61 to extract the water stored in the second water tank 2 and provide it to the heating device 62 and the cleaning device 63 connected to the water outlet of the heating device 62, and starts the heating device 62 and the cleaning device 63 to realize the cleaning function. When the detected liquid level is abnormal (the liquid level is less than the predetermined liquid level or less than the predetermined liquid level for a predetermined time), the controller of the flushing system controls the human body cleaning system to shut down and issues a water shortage alarm to prevent the heating device 62 from drying out and being damaged.
