Water-making equipment usually includes water tanks and water-making modules (used for cooling, heating, making soda, etc.). During the use of water-making equipment, due to the existence of water flow channels inside, microorganisms and bacteria will gradually accumulate in the pipes under long-term use, polluting the quality of drinking water, so regular cleaning and maintenance are required.

[0045] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0047] The following is combined with Figures 1 - 11Describe the water treatment equipment according to the embodiments of the present invention. The water treatment equipment provided by the embodiments of the present invention is used to process the raw water introduced into the water treatment equipment and then supply it to users. The treatment includes but is not limited to filtration, heating, refrigeration, adding soda, etc. The water treatment equipment can be a tabletop water dispenser.

[0048] As Figures 1 - 7 shown, the water treatment equipment provided by the embodiments of the present invention includes: a water tank 220, a water treatment module, a water pump 230, a circulating water pipe 306, and a controller (not shown in the figure).

[0049] Among them, the water tank 220 is used for storing water. The water inlet 221 of the water tank 220 is connected to the water inlet 101 of the water treatment equipment. The water inlet 101 can be directly or indirectly connected to the raw water pipe. For example, the raw water pipe can be a tap water pipe, and the raw water flows into the water treatment equipment from the water inlet 101.

[0050] The water inlet of the water treatment module is connected to the water outlet 222 of the water tank 220, and the water outlet of the water treatment module is connected to the water supply port of the water treatment equipment. The water tank 220 is used to supply water to the water treatment module, and the water treatment module is used to process the water provided by the water tank 220, including but not limited to refrigeration, heating, making soda, etc.

[0051] The circulating water pipe 306 is connected between the water return port of the water treatment module and the water tank 220. As Figures 1 - 7 shown, the water return port of the water treatment module can be connected to the water inlet 221 of the water tank 220, or the water return port of the water treatment module can also be connected to the top of the water tank 220.

[0052] The drain port of the water treatment module is connected to the waste water outlet 102 of the water treatment equipment, and the drain port is arranged at the bottom of the water treatment module. The drain port is higher than the waste water outlet 102 of the water treatment equipment. In this way, the stale water in the water treatment module can be discharged to the waste water outlet 102 under the action of gravity through the drain port.

[0053] The water pump 230 is used to drive water to flow from the water tank 220 to the water treatment module. In some embodiments, the water pump 230 is connected between the water outlet 222 of the water tank 220 and the water inlet of the water treatment module.

[0054] When the water treatment equipment supplies water to users, the water pump 230 drives water to flow sequentially through the water tank 220, the water inlet of the water treatment module, the water outlet of the water treatment module, and the water supply port; when draining is required, the water pump 230 can drive the water in the water tank 220 into the water treatment module and discharge it through the drain port of the water treatment module; when replenishing water to the water treatment equipment, the water pump 230 can drive water to flow sequentially through the water tank 220 and the water inlet of the water treatment module, and when the water level in the water treatment module reaches the set position, the water pump 230 can drive water to circulate between the water tank 220, the water inlet of the water treatment module, the water return port of the water treatment module, and the water tank 220.

[0055] The controller is electrically connected to the water pump 230. The water production module is electrically connected to the controller.

[0056] The water production device has a cleaning mode. In the cleaning mode, the controller is set to control the water pump 230 to sequentially empty the water tank 220 and the water production module, then replenish water to the water tank 220 and the water production module in sequence, and drive water to circulate among the water tank 220, the water production module, and the circulation water pipe 306.

[0057] It can be understood that when the water production device needs to be cleaned, the controller controls the water production module to close to prevent damage to the water production module after drainage.

[0058] The controller controls the water pump 230 to start. The water pump 230 operates to drain the water in the water tank 220 into the water production module, and the water in the water production module is discharged through the drain port.

[0059] In other words, the water in both the water tank 220 and the water production module is emptied through the drain port of the water production module, and the water in the water tank 220 is pumped out by the water pump 230. In this way, there is no need to set a water level difference between the water tank 220 and the water production module, and the water in the water production module is emptied under the action of gravity, which can be achieved simply by setting the drain port at the bottom of the water production module.

[0060] After the water in the water tank 220 and the water production module is emptied, it is necessary to replenish water with a cleaning agent into the water tank 220 and the water production module, and the replenishment sequence is the water tank 220 first and then the water production module. After the water replenishment is completed, the water pump 230 drives water to circulate among the water tank 220, the water production module, and the circulation water pipe 306 to clean the water tank 220, the water production module, and the pipeline.

[0061] According to the water production device of the embodiment of the present invention, when cleaning is required, the water pump 230 can effectively empty each container in the water production device, and there is no need to set a water level difference between the water tank 220 and the water production module, which helps to reduce the size of the water production device. After emptying, the water pump 230 can fill the water tank 220 and the water production module in sequence again, and drive the water with a cleaning agent to circulate in the pipeline, and the cleaning effect is good.

[0062] In some embodiments, as Figures 1 - 7 shown, the water production device of the embodiment of the present invention may further include: an inlet control valve 303, a drain control valve, a water level detection device 223, and an inlet control valve 303.

[0063] The water inlet control valve 303 is connected between the water inlet 221 of the water tank 220 and the water inlet 101 of the water treatment device. The water inlet control valve 303 is electrically connected to the controller, and the controller is configured to control the water inlet control valve 303 according to the signal of the water level detection device 223. When the water inlet control valve 303 is open, the water inlet 101 of the water treatment device is in communication with the water inlet 221 of the water tank 220. When the water inlet control valve 303 is closed, the water inlet 101 of the water treatment device is disconnected from the water inlet 221 of the water tank 220.

[0064] The water level detection device 223 is used to detect the water level of the water tank 220, and the water level detection device 223 is electrically connected to the controller.

[0065] It can be understood that the water tank 220 may be provided with a water level detection device 223. The water level detection device 223 is used to detect the water level of the water tank 220. The water level detection device 223 may be a liquid level gauge. When the water treatment device is in normal use, the controller is configured to control the water inlet control valve 303 according to the signal of the water level detection device 223.

[0066] During water replenishment, if the water level of the water tank 220 does not reach the target water level, the controller controls the water inlet control valve 303 to open to supply water to the water tank 220. When the water level of the water tank 220 reaches the target water level, the controller controls the water inlet control valve 303 to close. The water inlet control valve 303 may be a solenoid valve.

[0067] The drain control valve is connected between the drain port of the water treatment module and the waste water outlet 102 of the water treatment device. The drain control valve is electrically connected to the controller. During drainage, the controller is configured to control the drain control valve to open. When the water treatment device is in normal use, the drain control valve is closed. During drainage, the drain control valve is open. During drainage, the signal of the water level detection device 223 is blocked, and the water inlet control valve 303 is controlled to remain closed to avoid interfering with drainage.

[0068] In the cleaning mode, the controller is configured to control the water inlet control valve 303 to close, the drain control valve to open, and the water pump 230 to close after being opened for a first target time. After the water pump 230 is closed, the drain control valve remains open for a second target time and then closes to sequentially empty the water tank 220 and the water treatment module.

[0069] The first target time is determined based on the capacity of the water tank 220 and the flow rate of the water pump 230. In this way, it is not necessary to monitor the water level of the water tank 220 during drainage, and it can be simply ensured that the water tank 220 is emptied. In actual implementation, the first target time is related to the capacity of the water tank 220 and the flow rate of the water pump 230, and at the same time, the different resistances caused by the pipeline length need to be considered.

[0070] For example, in one embodiment, the capacity of the water tank 220 is 2L, the flow rate of the water pump 230 is 3L / min. Considering the actual flow attenuation of the pipeline, the first target time is set to 50s, and the water tank 220 can be emptied accordingly.

[0071] The second target time is determined based on the capacity of the water production module and the caliber of the drain outlet, etc. In this way, when draining water, it is not necessary to monitor the water level of the water production module, and it can be simply ensured that the water production module is emptied.

[0072] In the cleaning mode, the controller is also set to, after the water tank 220 and the water production module are emptied in sequence, control the inlet control valve 303 to open, confirm that the water pump 230 is in the open state, and confirm that the water level of the water tank 220 remains above the target water level within the target time period, and then control the inlet control valve 303 to close.

[0073] When replenishing water to the water tank 220 and the water production module in the cleaning mode, the water pump 230 is in the open state, and the water in the water tank 220 is pumped to the downstream water production module. If the water level of the water production module does not reach the set position, the water level of the water tank 220 will decrease. If the water level of the water tank 220 does not reach the target water level, it means that the water level of the water production module may be insufficient. If the water level of the water tank 220 reaches the target water level within a short time but cannot be maintained, it means that the water in the water tank 220 is still being pumped to the downstream water production module, and the water level of the water production module may still be insufficient. By determining that the water level of the water tank 220 remains above the target water level within the target time period, it can be ensured that both the water tank 220 and the water production module are filled with water.

[0074] When the water level of the water production module reaches the set position, the water pump 230 continues to pump the water in the water tank 220 into the water production module, and the water in the water production module will flow back to the water tank 220 through the water return port of the water production module, so that the water level of the water tank 220 can be maintained.

[0075] In some embodiments, the controller is also set to, when determining that the water level of the water tank 220 is above the target water level for the first time, control the water pump 230 to start.

[0076] It should be noted that in the cleaning mode, when first emptying the water tank 220 and the water production module and then replenishing the water tank 220 and the water production module with water containing cleaning agent, first replenish water to the water tank 220. When the water level of the water tank 220 does not reach the target water level, the controller controls the water pump 230 to close, and gives priority to filling the water tank 220. When the water level of the water tank 220 is above the target water level, then control the water pump 230 to start.

[0077] In other words, taking the water level of the water tank 220 being above the target water level as the trigger signal for starting the water pump 230 can prevent the water pump 230 from dry pumping.

[0078] In some embodiments, the water treatment device may further include: a water supply control valve connected between the water outlet of the water treatment module and the water supply port. The controller is electrically connected to the water supply control valve. The controller is configured to control the water pump 230 to drive water to circulate between the water tank 220, the water treatment module, and the circulation water pipe 306 for a target circulation time, and then control the water supply control valve to open.

[0079] In other words, after the water with the cleaning agent circulates between the water tank 220, the water treatment module, and the circulation water pipe 306 for a target circulation time, the water tank 220 and the water treatment module can be cleaned. At this time, by opening the water supply control valve, the water with the cleaning agent can be discharged from the water supply pipeline to achieve the cleaning of the water supply pipeline.

[0080] It should be noted that the water supply control valve can be opened only for a preset time, and then the remaining water with the cleaning agent is discharged through the drain outlet of the water treatment module. The drainage method is the same as the method of draining clear water at the beginning.

[0081] In some embodiments, as Figures 1 - 7 shown, a vent 224 is provided at the top of the water tank 220. The vent 224 is communicated with the outside. The water outlet of the water treatment module is connected to the top of the water tank 220 through an exhaust pipeline. In this way, the inside of the water treatment device is in communication with the atmosphere, and there will be no sudden change in air pressure inside the water treatment device during cyclic water replenishment, making it safer to use. A breathable cotton can be installed at the vent 224 to prevent foreign impurities from entering the water tank 220 and ensure water quality safety.

[0082] In some embodiments, as Figures 1 - 7 shown, the water treatment device may further include: a filtration module 210 connected between the water inlet 221 of the water tank 220 and the water inlet 101 of the water treatment device. In this way, the raw water to be filtered flows into the water tank 220 for storage after being filtered by the filtration module 210, and the water treatment device can provide pure water.

[0083] The filtration module 210 includes a first filter element 211 and a second filter element 212. The water inlet end of the first filter element 211 is connected to the water inlet 101. The water outlet end of the first filter element 211 is connected to the water inlet end of the second filter element 212 through a water inlet control valve 303. The water outlet end of the second filter element 212 is connected to the water inlet 221 of the water tank 220.

[0084] The first filter element 211 is used to achieve preliminary filtration of the raw water, and can filter out large particulate matters such as sediment, rust, insect eggs, and bloodworms in the raw water. The raw water can be tap water, well water, etc. The first filter element 211 can be a PP cotton filter element (polypropylene meltblown filter element) or a composite filter element, etc.

[0085] The second filter element 212 is used to adsorb odors and residual chlorine, and can be used to improve the taste of pure water. The third filter element can be an activated carbon filter element.

[0086] Of course, a reverse osmosis filter element can also be arranged between the first filter element 211 and the second filter element 212. The pore size of the reverse osmosis membrane is very small, which can effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic substances in water.

[0087] In the cleaning mode, the original filter element in the filtration module 210 can be taken out and a cleaning filter element with a cleaning agent can be installed. In this way, when the raw water passes through the filtration module 210, the cleaning agent can be injected into the water tank 220 and the water production module.

[0088] Of course, the cleaning agent can also be added to the water production equipment in other ways, including directly pouring the cleaning agent into the water tank 220.

[0089] In some embodiments, as Figures 1 - 7 shown, the water production module includes: a first water production module 240 and a second water production module 250.

[0090] The water inlet 241 of the first water production module 240 is connected to the water outlet 222 of the water tank 220, and the water outlet 242 of the first water production module 240 is connected to the first water supply port 103 of the water production equipment; the water inlet 251 of the second water production module 250 is connected to the water outlet 222 of the water tank 220, and the water outlet 252 of the second water production module 250 is connected to the second water supply port 104 of the water production equipment.

[0091] The first water production module 240 and the second water production module 250 are used to perform different treatments or processes on the water drawn from the water tank 220. In this way, the water production equipment can provide multiple types of beverages to users.

[0092] In some embodiments, as Figures 1 - 7 shown, the water return port 244 of the first water production module 240 and the water return port 254 of the second water production module 250 are connected to the water tank 220 through the same circulation water pipe 306, and the circulation water pipe 306 is provided with a circulation control valve 307, and the circulation control valve 307 is electrically connected to the controller.

[0093] In other words, the two water production modules share the circulation water pipe 306. In this way, the components of the entire water production equipment are fewer, which is convenient for arrangement and control.

[0094] Of course, in other embodiments, the water return port 244 of the first water production module 240 and the water return port 254 of the second water production module 250 are connected to the water tank 220 through their respective corresponding circulation water pipes 306, and each circulation water pipe 306 is provided with a circulation control valve 307, and the circulation control valve 307 is electrically connected to the controller. In other words, each water production module can be equipped with an independent circulation water pipe 306 and a circulation control valve 307 to prevent water flow cross - flow.

[0095] In some embodiments, the first water production module is a heating module, and the second water production module 250 is a refrigeration module. The heating module includes a tank body and a heating device, and the heating device may include an electric heater. The refrigeration module includes a tank body and a refrigeration device, and the refrigeration device may include an evaporator or a thermoelectric cooler, etc.

[0096] As Figures 1 - 7 shown, the first water production module is a heating module. The water inlet 241 of the first water production module 240 is provided at the lower part of the first water production module, and the water outlet 242 of the first water production module 240 is provided at the upper part of the first water production module. During the operation of the first water production module, hot water floats upward and normal temperature water sinks downward. Through the water outlet 242 of the first water production module 240 provided at the upper part of the first water production module, hot water can be taken to the greatest extent, improving the actual effective utilization efficiency of the first water production module.

[0097] As Figures 1 - 7 shown, in this embodiment, the water return port 244 of the first water production module 240 is integrated with the water outlet 242 of the first water production module 240. In this way, fewer water ports are opened on the first water production module, and the pipeline can also be reduced.

[0098] In Figures 1 - 7 the embodiment shown, the water inlet 241 of the first water production module 240 and the drain port 243 of the first water production module 240 are integrated into the same water port, and the water inlet 241 of the first water production module 240 and the drain port 243 of the first water production module 240 are provided at the bottom of the first water production module; the water return port 244 of the first water production module 240 and the water outlet 242 of the first water production module 240 are integrated into the same water port, and the water return port 244 of the first water production module 240 and the water outlet 242 of the first water production module 240 are provided at the top of the first water production module. The water outlet 242 of the first water production module 240 is also connected to the top of the water tank 220 through a first exhaust pipe 225. A damping plug can be installed on the first exhaust pipe 225, and the aperture of the damping plug is relatively small. For example, the aperture of the damping plug can be 0.3 mm - 0.5 mm.

[0099] As Figures 1 - 7 shown, the water inlet 251 of the second water production module 250 is provided at the upper part of the second water production module 250, and the water outlet 252 of the second water production module 250 communicates with the lower part of the second water production module 250. During the operation of the second water production module 250, cold water sinks downward and normal temperature water floats upward. By communicating the water outlet 252 of the second water production module 250 with the lower part of the second water production module 250, cold water can be taken to the greatest extent, improving the actual effective utilization efficiency of the second water production module 250.

[0100] In Figures 1 - 7In the illustrated embodiment, the water inlet 251 of the second water production module 250 is provided at the top of the second water production module 250, the water outlet 252 of the second water production module 250 is provided at the top of the second water production module 250 and extends to the lower part of the second water production module 250 through a water outlet pipe, the drain outlet 253 of the second water production module 250 is provided at the bottom of the second water production module 250, and the drain outlet 253 and the water return port 254 of the second water production module 250 are integrated into the same water port.

[0101] The water outlet 252 of the second water production module 250 is also connected to the top of the water tank 220 through a second exhaust pipe 226. A damping plug can be installed on the second exhaust pipe 226, and the aperture of the damping plug is relatively small. For example, the aperture of the damping plug can be 0.3 mm - 0.5 mm. Of course, the exhaust of the second water production module 250 can also be realized through other structures. For example, an exhaust hole can be provided at the water pipe at the water outlet 252 of the second water production module 250. The exhaust hole can be 0.5 mm - 1.5 mm. The top cover of the second water production module 250 is provided with a separate exhaust cavity, and the exhaust hole is located in the exhaust cavity.

[0102] Add a small hole to the cold tank cover, combined with the principle that the start-up solenoid valve automatically opens to discharge air for a certain period of time.

[0103] As Figures 1 - 7 shown, in this embodiment, the water return port 254 of the second water production module 250 is integrated into the drain outlet 243 of the first water production module 240. In this way, fewer water ports are opened on the second water production module 250, and the pipelines can also be reduced.

[0104] Of course, in other embodiments, the water inlet, water outlet, water return port, and drain outlet can also be independently provided on the water production module, which will not be elaborated here.

[0105] In some embodiments, as Figures 1 - 7 shown, a switching valve 320 is installed on the circulating water pipe 306. The switching valve 320 has a first valve port 321, a second valve port 322, and a third valve port 323 that can be selectively communicated. The water return port and the drain outlet of the water production module are both connected to the first valve port 321. The second valve port 322 is connected to the waste water outlet 102 of the water production device, and the third valve port 323 is connected to the water tank 220. The switching valve 320 is electrically connected to the controller.

[0106] In this way, the circulating control valve 307 is equivalent to being integrated in the switching valve 320. Through a single switching valve 320, the switching of the drainage and water replenishment water circuits can be achieved, and the water circuit of the entire water production device is simpler.

[0107] In some embodiments, as Figure 10 and Figure 11As shown, the switching valve 320 can be a solenoid valve, and the switching valve 320 can include: a control coil 324, a valve core 325, a valve bracket 326, and a valve seat 327.

[0108] Among them, the valve bracket 326 is connected to the valve seat 327, and a valve passage is defined within the valve bracket 326 and the valve seat 327. The valve seat 327 is provided with a first valve port 321 and a second valve port 322 that communicate with the valve passage, and the valve bracket 326 is provided with a second valve port 322 that communicates with the valve passage. The valve core 325 is movably installed in the valve bracket 326, and the valve core 325 extends into the valve seat 327. The control coil 324 is used to control the movement of the valve core 325.

[0109] As Figure 10 shown, when the switching valve 320 is powered off, the first valve port 321 and the second valve port 322 are in communication, that is, in the natural state, the third valve port 323 is cut off from the first valve port 321. In this way, the switching valve 320 can play a role in stopping water. Since a water stop device 500 is connected to the second valve port 322, even if the second valve port 322 is in communication with the first valve port 321, there will be no water leakage; as Figure 11 shown, when the switching valve 320 is powered off, the control coil 324 drives the valve core 325 to move, so that the valve core 325 moves to a position where the first valve port 321 and the third valve port 323 are in communication, and at this time, the first valve port 321 and the second valve port 322 are cut off.

[0110] In some embodiments, as Figure 8 and Figure 9 shown, the water stop device 500 includes: a main housing 510 and a water stop portion 520.

[0111] The main housing 510 defines a channel 518 that is open at both ends. The first end of the channel 518 is connected to the second valve port 322, and the second end of the channel 518 is connected to the wastewater outlet 102 of the water treatment device. When the channel 518 is in a connected state, the wastewater outlet 102 of the water treatment device is opened, and drainage can be achieved.

[0112] The water stop portion 520 is movably installed in the main housing 510, and the water stop portion 520 can selectively cut off both ends of the channel 518.

[0113] As Figure 8 shown, in the natural state, the water stop portion 520 cuts off both ends of the channel 518, blocking the wastewater outlet 102; as Figure 9 shown, by moving the water stop portion 520, both ends of the channel 518 can be made to communicate, that is, the wastewater outlet 102 is opened.

[0114] In some embodiments, as Figure 8 shown, the main housing 510 includes: an upper cover 511, a main pipe body 515, and a seal 517.

[0115] The upper cover 511 may include a top wall and a peripheral wall. The top wall is flat, and the peripheral wall surrounds the top wall. A through hole 514 is provided in the top wall of the upper cover 511. The upper cover 511 covers the outside of the main body 515, and the main body 515 communicates with the through hole 514. The water stop portion 520 is movably installed in the main body 515, and the seal 517 is installed between the main body 515 and the upper cover 511. One of the upper cover 511 and the main body 515 is connected to the drain outlet of the water production module, and the other of the upper cover 511 and the main body 515 is connected to the waste water outlet 102 of the water production device. For example, the upper cover 511 is connected to the drain outlet of the water production module, and the main body 515 is connected to the waste water outlet 102 of the water production device.

[0116] In this way, through the covering structure of the upper cover 511 and the main body 515, and the sealing of the seal 517, the main housing 510 is convenient to form and has good sealing performance.

[0117] In some embodiments, as Figure 8 shown, an inner tube 512 protruding inwardly of the upper cover 511 is provided on the top wall of the upper cover 511. The inner tube 512 communicates with the through hole 514. The main body 515 is sleeved outside the inner tube 512. The seal 517 is bent, and a part of the seal 517 is clamped between the inner peripheral wall of the main body 515 and the outer peripheral wall of the inner tube 512, and another part of the seal 517 is clamped between the end of the main body 515 and the top wall of the upper cover 511.

[0118] In this way, the peripheral wall of the upper cover 511, the main body 515 and the inner tube 512 form a three-layer sleeved structure. The bent seal 517 realizes sealing in the axial and radial directions, and the main housing 510 has good sealing performance and is not easy to leak water.

[0119] In some embodiments, as Figure 8 shown, an outer tube 513 protruding outwardly of the upper cover 511 is provided on the top wall of the upper cover 511. The outer tube 513 is equivalent to a joint for realizing the assembly between the main body 515 and the pipeline.

[0120] The upper cover 511, the inner tube 512 and the outer tube 513 can be formed integrally. The inner diameter of the inner tube 512 is larger than the inner diameter of the outer tube 513, which can increase the flow area at the inner tube 512 to prevent excessive water pressure at the main housing 510 during drainage, and the reliability of the main housing 510 is higher.

[0121] In some embodiments, as Figure 8 shown, a support portion 516 protruding inwardly is provided on the inner peripheral wall of the main body 515. The support portion 516 defines a flow hole 519. The support portion 516 can be annular, and the flow hole 519 is formed in the middle of the support portion 516.

[0122] AsFigure 8 As shown in the figure, the water stop part 520 includes: a guide post 521, a water stop plug 522 and an elastic member 523.

[0123] The guide post 521 penetrates through the flow through hole 519, and the guide post 521 is in clearance fit with the flow through hole 519. The outer diameter of the guide post 521 is smaller than the aperture of the flow through hole 519, and an annular gap is formed between the guide post 521 and the flow through hole 519, and this gap is used for draining water.

[0124] The water stop plug 522 is connected to the guide post 521, and the sealing surface of the water stop plug 522 is adapted to completely cover the flow through hole 519. When the sealing surface of the water stop plug 522 is attached to the support part 516, the flow through hole 519 can be covered, and the flow through hole 519 is blocked, and the water stop device 500 blocks the waste water outlet 102; when the sealing surface of the water stop plug 522 is separated from the support part 516, both ends of the through hole 514 are communicated through the flow through hole 519.

[0125] The elastic member 523 is elastically connected between the guide post 521 and the support part 516, and in the natural state, the elastic member 523 is used to make the sealing surface of the water stop plug 522 abut against the support part 516.

[0126] In some embodiments, as Figure 8 shown, a sealing boss 516a can be provided on one side of the support part 516 facing the sealing surface. The sealing boss 516a is annular. When the sealing surface of the water stop plug 522 is attached to the sealing boss 516a, the flow through hole 519 can be covered, and the flow through hole 519 is blocked. The contact area between the sealing surface of the water stop plug 522 and the sealing boss 516a is smaller than that of directly contacting the support part 516. When the elastic force provided by the elastic member 523 is constant, the pressure between the sealing surface of the water stop plug 522 and the sealing boss 516a is greater, the elastic deformation of the water stop plug 522 is greater, and the sealing effect is higher.

[0127] In some embodiments, as Figure 8 shown, the water stop device 500 further includes: a drain pipe (not shown in the figure) and a push rod 530. The drain pipe is used to be connected to the main body 515; the push rod 530 is installed in the drain pipe and is used to abut against the guide post 521 to deform the elastic member 523 until the sealing surface of the water stop plug 522 is separated from the support part 516.

[0128] During actual use, by using the push rod 530 to push open the guide post 521, the sealing surface of the water stop plug 522 can be separated from the support part 516. When the push rod 530 is released, under the elastic force of the elastic member 523, the sealing surface of the water stop plug 522 automatically fits with the support part 516.

[0129] Next, a water production device provided by an embodiment of the present invention will be described in conjunction with Figure 1 the following.

[0130] As shown Figure 1 in the figure, the water purification device includes: a first filter element 211, a second filter element 212, a water tank 220, a water pump 230, a first water purification module, a second water purification module 250 and a controller.

[0131] The water inlet 101 of the water purification device can be used to connect to raw water (such as tap water). The water inlet of the first filter element 211 is connected to the water inlet 101, and a pressure reducing valve 301 and a leak-proof valve 302 are sequentially installed between the water inlet 101 of the water purification device and the water inlet of the first filter element 211. The pressure reducing valve 301 is used to reduce the water pressure flowing into the water purification device, playing a protective role for the water purification device, and the leak-proof valve 302 is used to monitor whether the water purification device leaks.

[0132] An inlet control valve 303 is installed between the water outlet of the first filter element 211 and the water inlet of the second filter element 212, and the water outlet of the second filter element 212 is connected to the water inlet 221 of the water tank 220.

[0133] During the normal use of the water purification device, the water tank 220 is used to store the purified water filtered by the first filter element 211 and the second filter element 212. A water level detection device 223 can be installed in the water tank 220. The bottom of the water tank 220 is provided with a water outlet, and the top of the water tank 220 is also provided with a ventilation port 224. A sterilization module 109 is also installed on the inner side of the top wall of the water tank 220. The sterilization module 109 is used to sterilize the water tank 220, and the sterilization module 109 can be an ultraviolet lamp.

[0134] The water inlet of the water pump 230 is connected to the water outlet 222 of the water tank 220, and the water outlet of the water pump 230 is connected to the water inlet 241 of the first water purification module 240 and the water inlet 251 of the second water purification module 250.

[0135] The first water purification module 240 is a heating module, and the second water purification module 250 is a refrigeration module.

[0136] The water inlet 241 and the drain outlet 243 of the first water purification module 240 are integrated into the same water port, and the water inlet 241 and the drain outlet 243 of the first water purification module 240 are provided at the bottom of the first water purification module 240; the water return port 244 and the water outlet 242 of the first water purification module 240 are integrated into the same water port, and the water return port 244 and the water outlet 242 of the first water purification module 240 are provided at the top of the first water purification module. The water outlet 242 of the first water purification module 240 is also connected to the top of the water tank 220 through a first exhaust pipe 225. A damping plug can be installed on the first exhaust pipe 225, and the aperture of the damping plug is relatively small. For example, the aperture of the damping plug can be 0.3 mm - 0.5 mm.

[0137] An inlet check valve 245 is installed at the water inlet 241 of the first water production module 240, and the inlet check valve 245 conducts unidirectionally from the water outlet of the water pump 230 to the water inlet 241 of the first water production module 240.

[0138] The water inlet 251 of the second water production module 250 is provided at the top of the second water production module 250. The water outlet 252 of the second water production module 250 is provided at the top of the second water production module 250 and extends to the lower part of the second water production module 250 through a water outlet pipe. The drain port 253 of the second water production module 250 is provided at the bottom of the second water production module 250, and the drain port 253 and the water return port 254 of the second water production module 250 are integrated into the same water port. The water outlet 252 of the second water production module 250 is also connected to the top of the water tank 220 through a second exhaust pipe 226. A damping plug can be installed on the second exhaust pipe 226, and the aperture of the damping plug is relatively small. For example, the aperture of the damping plug can be 0.3 mm - 0.5 mm.

[0139] A first water supply control valve 106 is installed between the water outlet 242 of the first water production module 240 and the first water supply port 103. The first water supply control valve 106 can be used to supply hot water. A second water supply control valve 107 is installed between the water outlet 252 of the second water production module 250 and the second water supply port 104. The second water supply control valve 107 can be used to supply cold water. A third water supply control valve 108 is installed between the water outlet of the water pump 230 and the third water supply port 105. The third water supply control valve 108 can be used to supply normal temperature water. The third water supply port 105 and the second water supply port 104 can be integrated into a water supply port, and a sterilization module 109 can be provided at this water supply port to sterilize the normal temperature water or cold water.

[0140] The switching valve 320 has a first valve port 321, a second valve port 322, and a third valve port 323 that can be selectively connected. The water return port 244 and the drain port 243 of the first water production module 240 are both connected to the first valve port 321. The water return port 254 and the drain port 253 of the second water production module 250 are both connected to the first valve port 321. The second valve port 322 is connected to the wastewater outlet 102 of the water production equipment, and the third valve port 323 is connected to the water inlet 221 of the water tank 220.

[0141] A drain check valve 310 and a water stop device 500 are connected between the second valve port 322 and the wastewater outlet 102 of the water production equipment. The drain check valve 310 conducts unidirectionally from the second valve port 322 to the wastewater outlet 102, and the drain check valve 310 is used to prevent wastewater from flowing back.

[0142] The water level detection device 223, the water inlet control valve 303, the water pump 230, the first water supply control valve 106, the second water supply control valve 107, the third water supply control valve 108, and the switching valve 320 are all electrically connected to the controller.

[0143] The following combines Figures 2 - 11 to describe the cleaning process of the water treatment equipment according to the embodiments of the present invention.

[0144] As Figure 2 shown, when the water treatment equipment is in normal use, the water tank 220, the first water treatment module 240, and the second water treatment module 250 are all filled with water, and the water stop device 500 is as Figure 8 shown.

[0145] When it is necessary to clean the water treatment equipment, replace the cleaning filter element. The push rod 530 of the water stop device 500 is pushed into the main housing 510, so that the push rod 530 abuts against the guide post 521, the elastic member 523 is compressed, and the sealing surface of the water stop plug 522 is separated from the support portion 516, so that the waste water outlet 102 is opened.

[0146] The user operates the button or the touch panel to make the water treatment equipment enter the cleaning mode.

[0147] As Figure 2 shown, in the cleaning mode, the controller is set to control the water treatment module to be closed, and the signal of the water level detection device 223 is blocked, so that the water inlet control valve 303 remains closed. The controller also closes the first water supply control valve 106, the second water supply control valve 107, and the third water supply control valve 108 to prevent water from flowing out of the water supply port during the drainage process.

[0148] As Figure 2 shown, the controller controls the first drainage control valve 304 to open, controls the second drainage control valve 305 to open, and turns on the water pump 230. After the first target time, the water tank 220 can be emptied, as Figure 3 shown. The first target time is related to the capacity of the water tank 220 and the flow rate of the water pump 230, and at the same time, the different resistances caused by the pipeline length need to be considered.

[0149] As Figure 3 shown, after the water tank 220 is emptied, the controller turns off the water pump 230, continues to keep the first drainage control valve 304 open, controls the second drainage control valve 305 to open, and after the second target time, the first water treatment module 240 and the second water treatment module 250 are emptied by gravity.

[0150] As Figure 4As shown, the controller controls the water inlet control valve 303 according to the water level information of the water tank 220 detected by the water level detection device 223, and controls the water pump 230 to close before the water level detection device 223 first detects that the water level of the water tank 220 reaches the target water level. In other words, priority is given to filling the water tank 220 with water.

[0151] As Figure 5 shown, when the water level detection device 223 detects that the water level of the water tank 220 reaches the target water level, the controller controls the water pump 230 to start, energizes the switching valve 320, and the controller is set to control the water inlet control valve 303 according to the signal of the water level detection device 223. The water pump 230 operates to pump water from the water tank 220 to the first water production module 240 and the second water production module 250. When the water level of the water tank 220 drops below the target water level, the water inlet control valve 303 opens to fill the water tank 220 with water, so as to ensure that the water tank 220 has enough water to supply the first water production module 240 and the second water production module 250. In the water production module water replenishment mode, the air in the first water production module 240 and the second water production module 250 flows to the water tank 220 through the water return port of the water production module. In the water tank water replenishment mode, the first water supply control valve 106, the second water supply control valve 107 and the third water supply control valve 108 are closed. The first valve port 321 of the switching valve 320 is communicated with the third valve port 323.

[0152] As Figure 6 shown, the controller is set to determine that if the water level detected by the water level detection device 223 in the water tank 220 remains above the target water level within the target time period, it is determined that both the water tank 220 and the water production module are filled with water, and the water pump 230 continues to operate to make the water with cleaning agent circulate between the water tank 220 - water production module - circulation pipeline. Of course, the water pump 230 can also be turned off and the cleaning can be carried out by static immersion. The time for the water pump 230 to drive the circulation of the water with cleaning agent can be set to 5 - 15 minutes, such as 10 minutes.

[0153] As Figure 7 shown, after the circulation ends, the controller controls the switching valve 320 to de-energize, the first drain control valve 304 to close, and the second drain control valve 305 to close. The first water supply control valve 106, the second water supply control valve 107 and the third water supply control valve 108 can be sequentially opened to clean the hot water supply pipeline, the cold water supply pipeline and the normal temperature water supply pipeline, and drain through the waste water outlet 102.

[0154] After the cleaning of the water supply pipeline is completed, the system will pause and prompt to replace the filter element. At this time, reinstall the normal filter element into the filtration module 210. After replacing the filter element, the cleaning function can be reactivated with one key, and the water production equipment can enter the steps of draining, replenishing water, and circulating cleaning again, and clean the water tank 220, the water production module, and the pipeline with clean water. The cleaning time with clean water can be shorter than that with cleaning agent.

[0155] After the cleaning is completed, the water production equipment can re-enter the normal water production state.

[0156] In summary, the water production equipment of the embodiment of the present invention can achieve one-key cleaning, and the cleaning sequence is draining, replenishing water with cleaning agent, circulating, cleaning the water supply pipeline, draining, replenishing clean water, etc., which is equivalent to cleaning all the pipelines of the water production equipment.

[0157] Of course, according to the local water quality, different cleaning agents can be selected, or multiple cleaning agents can be used for sequential cleaning.

[0158] Of course, the first water production module for heating can also be turned on, and cleaning can be achieved through the circulating flow of hot water.

[0159] The present invention also provides a control method for a water production equipment.

[0160] Next, refer to Figure 12 and Figure 13 to describe the control method for the water production equipment provided by the embodiment of the present invention. The control method for the water production equipment provided by the embodiment of the present invention is mainly used for cleaning the water production equipment.

[0161] The water production equipment includes a water tank 220, a water production module, a water pump 230, and a circulating water pipe 306. The water inlet 221 of the water tank 220 is connected to the water inlet 101 of the water production equipment. The water inlet of the water production module is connected to the water outlet 222 of the water tank 220. The water outlet of the water production module is connected to the water supply port of the water production equipment. The circulating water pipe 306 is connected between the water return port of the water production module and the water tank 220. The drain port of the water production module is connected to the waste water outlet 102 of the water production equipment, and the drain port is arranged at the bottom of the water production module, and the drain port is higher than the waste water outlet 102. The water pump 230 is used to drive water to flow from the water tank 220 to the water production module.

[0162] As Figure 10 shown, the control method for the water production equipment provided by the embodiment of the present invention includes step 610-step 640.

[0163] Step 610, receive a cleaning instruction.

[0164] In actual execution, the cleaning instruction can be generated by the user operating the corresponding button or touch screen on the water production equipment.

[0165] Step 620: Based on the cleaning instruction, control the water pump 230 to start to empty the water tank 220 and the water production module in sequence.

[0166] The water pump 230 starts first to drain the water in the water tank 220. After the water in the water tank 220 is pumped into the water production module, it can be discharged from the drain outlet of the water production module, and then the water in the water production module is discharged through the drain outlet.

[0167] Step 630: Fill the water tank 220 and the water production module with water in sequence.

[0168] First, fill the water tank 220 with water, and then fill the water production module with water.

[0169] Step 640: Control the water pump 230 to start to drive the water to circulate among the water tank 220, the water production module and the circulation water pipe 306.

[0170] After the water tank 220 and the water production module are both filled with water, the water pump 230 starts, which can drive the water to circulate among the water tank 220, the water production module and the circulation water pipe 306 to achieve cleaning.

[0171] According to the control method of the water production equipment in the embodiment of the present invention, one-key cleaning of the water production equipment can be realized.

[0172] In some embodiments, an inlet control valve 303 is provided between the water inlet 221 of the water tank 220 and the water inlet 101 of the water production equipment, a drain control valve is provided between the drain outlet of the water production module and the waste water outlet 102 of the water production equipment, a switching valve 320 is installed on the circulation water pipe 306, and the switching valve 320 has a first valve port 321, a second valve port 322 and a third valve port 323 that can be selectively connected. The water return port and the drain outlet of the water production module are both connected to the first valve port 321, the second valve port 322 is connected to the waste water outlet 102 of the water production equipment, and the third valve port 323 is connected to the water tank 220. Step 620: Based on the cleaning instruction, control the water pump 230 to start to empty the water tank 220 and the water production module in sequence, including: Step 621: Control the inlet control valve 303 to close, control the first valve port 321 of the switching valve 320 to be connected to the second valve port 322, control the drain control valve to open, and control the water pump 230 to close after starting for a first target time; Step 622: After the water pump 230 closes, the drain control valve remains open for a second target time and then closes.

[0173] The first target time is determined based on the capacity of the water tank 220 and the flow rate of the water pump 230. In this way, when draining water, there is no need to monitor the water level of the water tank 220, and it can be simply ensured that the water tank 220 is emptied. In actual execution, the first target time is related to the capacity of the water tank 220 and the flow rate of the water pump 230, and at the same time, the different resistances caused by the pipeline length need to be considered.

[0174] For example, in one embodiment, the capacity of the water tank 220 is 2L, the flow rate of the water pump 230 is 3L / min, and considering the actual flow attenuation of the pipeline, the first target time is set to 50s, and the water tank 220 can be emptied accordingly.

[0175] The second target time is determined based on the capacity of the water production module, the caliber of the drain port, etc. In this way, when draining water, there is no need to monitor the water level of the water production module, and it can be simply ensured that the water production module is emptied.

[0176] In some embodiments, step 630, sequentially replenishing water to the water tank 220 and the water production module, includes:

[0177] Step 631, controlling the inlet control valve 303 based on the water level of the water tank 220; step 632, determining that the water level of the water tank 220 is above the target water level, controlling the first valve port 321 of the switching valve 320 to communicate with the third valve port 323, and controlling the water pump 230 to start until it is determined that the water level of the water tank 220 remains above the target water level within the target time period.

[0178] When replenishing water to the water tank 220 and the water production module, the water pump 230 is in the on state, and the water in the water tank 220 is pumped to the downstream water production module. If the water level of the water production module does not reach the set position, the water level of the water tank 220 will decrease. If the water level of the water tank 220 does not reach the target water level, it means that the water level of the water production module may be insufficient. If the water level of the water tank 220 reaches the target water level within a short time but cannot be maintained, it means that the water in the water tank 220 is still being pumped to the downstream water production module, and the water level of the water production module may still be insufficient. By determining that the water level of the water tank 220 remains above the target water level within the target time period, it can be ensured that both the water tank 220 and the water production module are filled with water.

[0179] In some embodiments, as Figure 13 shown, after step 640, controlling the water pump 230 to start to drive the water to circulate between the water tank 220, the water production module and the circulation water pipe 306, it further includes: step 650, controlling the water supply control valve to open, and the water supply control valve is connected between the water outlet of the water production module and the water supply port.

[0180] In other words, after the water with the cleaning agent circulates between the water tank 220, the water production module and the circulation water pipe 306 for the target circulation time, the water tank 220 and the water production module can be cleaned. At this time, by opening the water supply control valve, the water with the cleaning agent can be discharged from the water supply pipeline, realizing the cleaning of the water supply pipeline.

[0181] It should be noted that the water supply control valve can be opened only for a preset time, and then the remaining water with the cleaning agent is discharged through the drain port of the water production module, and the drainage method is the same as the method of draining clear water at the beginning.
