[0039] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

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 any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0044] The following combination Figures 1-6 The water production equipment of an embodiment of the present invention is described. The water production equipment provided by the embodiment of the present invention is used to process raw water introduced into the water production equipment before providing it to users. The processing includes but is not limited to filtering, heating, cooling, and adding soda. The water production equipment can be a desktop water dispenser.

[0045] like Figures 1-4 As shown, the water production equipment provided by the embodiment of the present invention includes: a water tank 220, a water production module, a water pump 230 and a controller (not shown in the figure).

[0046] Among them, the water tank 220 is used to store water, and the water inlet 221 of the water tank 220 is connected to the water inlet 101 of the water production 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 production equipment from the water inlet 101.

[0047] The water inlet of the water production module is connected to the water outlet 222 of the water tank 220, and the water outlet of the water production module is connected to the water supply port of the water production equipment. The water tank 220 is used to supply water to the water production module, and the water production module is used to process the water provided by the water tank 220, including but not limited to cooling, heating, soda making, etc.

[0048] The drain outlet of the water production module is connected to the wastewater outlet 102 of the water production equipment. The drain outlet is higher than the wastewater outlet 102 of the water production equipment. In this way, stale water in the water production module can be drained to the wastewater outlet 102 through the drain outlet under the action of gravity. The drain outlet can be located at the bottom of the water production module to ensure that the water production module is completely drained.

[0049] The water pump 230 is used to drive water from the water tank 220 to flow to the water production 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 production module.

[0050] When the water production equipment supplies water to users, the water pump 230 drives the water to flow through the water tank 220, the water inlet of the water production module, the water outlet of the water production module and the water supply port in sequence; when the water tank 220 needs to be drained, the water pump 230 can drive the water in the water tank 220 to flow to the water production module. In this way, there is no need to design an independent drain outlet for the drainage of the water tank 220, and the water tank 220 does not need to form a high and low water level difference with the water production module, which can reduce the size of the water production equipment.

[0051] The water pump 230 and the water production module are both electrically connected to the controller. The water production equipment has a drainage mode. In the drainage mode, the controller is set to control the water production module to be closed and control the water pump 230 to be turned on, and the water in the water production module is discharged through the drain outlet.

[0052] It is understood that when the water production equipment needs to be drained, the controller controls the water production module to shut down to prevent damage to the water production module after drainage. The controller controls the water pump 230 to start, and 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.

[0053] In other words, the water in the water tank 220 and the water production module is drained through the drain outlet 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. The water in the water production module is drained under the action of gravity, which can be achieved by simply setting the drain outlet at the bottom of the water production module.

[0054] According to the water production equipment of the embodiment of the present invention, the water in each container in the water production equipment can be effectively drained, 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 equipment.

[0055] In some embodiments, in the drainage mode, the controller is configured to control the water pump 230 to be turned on and then turned off after a target time, where the target time is determined based on the capacity of the water tank 220 and the flow rate of the water pump 230 .

[0056] In this way, there is no need to monitor the water level of the water tank 220 during drainage, and it is possible to simply ensure that the water tank 220 is emptied. In actual implementation, the target time is related to the capacity of the water tank 220 and the flow rate of the water pump 230, and different resistances caused by the length of the pipeline need to be considered.

[0057] For example, in one embodiment, the capacity of the water tank 220 is 2 L, the flow rate of the water pump 230 is 3 L / min, and the target time is set to 50 s based on the actual pipeline flow attenuation to empty the water tank 220 .

[0058] In some embodiments, as Figures 1-4 As shown, a drainage control valve is provided between the drainage port of the water production module and the wastewater outlet 102 of the water production equipment. The drainage control valve is electrically connected to the controller. In the drainage mode, the controller is configured to control the drainage control valve to open.

[0059] When the water-making equipment is in normal use, the drainage control valve is closed, and when draining, the drainage control valve is opened.

[0060] In some embodiments, as Figures 1-4 As shown, the water production equipment may also include: a water inlet control valve 303, 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 production equipment, the water inlet control valve 303 is electrically connected to the controller, and in the drainage mode, the controller is set to control the water inlet control valve 303 to be closed.

[0061] It can be understood that the water tank 220 can be provided with a water level detection device 223, which is used to detect the water level of the water tank 220. The water level detection device 223 can be a liquid level meter. When the water production equipment is used normally, the controller is set to control the water inlet control valve 303 according to the signal of the water level detection device 223.

[0062] In the drainage mode, the signal of the water level detection device 223 is shielded and the water inlet control valve 303 is controlled to remain closed to avoid interference with drainage.

[0063] In some embodiments, as Figures 1-4 As shown, the water production equipment may also include: a water supply control valve, the water supply control valve is connected between the water outlet and the water supply port of the water production module, the controller is electrically connected to the water supply control valve, and in the drainage mode, the controller is set to control the water supply control valve to close.

[0064] In other words, the water-making equipment according to the embodiment of the present invention does not need to drain water through the water supply port when draining water, so the drainage is more hygienic.

[0065] In some embodiments, as Figure 4As shown, the top of water tank 220 is provided with a vent 224, which communicates with the outside world. The water outlet of the water production module is connected to the top of water tank 220 via an exhaust pipe. This ensures that the water production equipment is connected to the atmosphere, preventing sudden changes in air pressure during water circulation and replenishment, making it safer to use. Ventilation 224 can be fitted with breathable cotton to prevent external impurities from entering water tank 220, ensuring water quality.

[0066] In some embodiments, as Figures 1-4 As shown, the water production equipment may further include: a filter module 210, which is connected between the water inlet 221 of the water tank 220 and the water inlet 101 of the water production equipment. In this way, the raw water to be filtered is filtered by the filter module 210 and then flows into the water tank 220 for storage, and the water production equipment can provide pure water.

[0067] 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 the water inlet control valve 303, and the water outlet end of the second filter element 212 is connected to the water inlet 221 of the water tank 220.

[0068] The first filter element 211 is used to achieve preliminary filtration of raw water, and can filter out large particles such as mud, rust, insect eggs, and red worms 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 melt-blown filter element) or a composite filter element, etc.

[0069] The second filter element 212 is used to absorb odor and residual chlorine, and can be used to improve the taste of purified water. The third filter element can be an activated carbon filter element.

[0070] Of course, a reverse osmosis filter element may also be arranged between the first filter element 211 and the second filter element 212. The reverse osmosis membrane has a very small pore size and can effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic matter in water.

[0071] In some embodiments, as Figures 1-4 As shown, the water production module includes: a first water production module 240 and a second water production module 250.

[0072] 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.

[0073] 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 a variety of beverages to users.

[0074] In some embodiments, as Figure 4 As shown, the water production equipment also includes: a circulating water pipe 306, the return water port 244 of the first water production module 240 and the return water port 254 of the second water production module 250 are connected to the water tank 220 through the same circulating water pipe 306, and the circulating water pipe 306 is provided with a circulating control valve 307, and the circulating control valve 307 is electrically connected to the controller.

[0075] In other words, the two water production modules share the circulating water pipe 306 and the circulating control valve 307. In this way, the entire water production equipment has fewer parts and components, which is convenient for layout and control.

[0076] Of course, in other embodiments, the return water inlet 244 of the first water production module 240 and the return water inlet 254 of the second water production module 250 are connected to the water tank 220 via corresponding circulating water pipes 306. Each circulating water pipe 306 is equipped with a circulating control valve 307, which is electrically connected to the controller. In other words, each water production module can be equipped with an independent circulating water pipe 306 and circulating control valve 307 to prevent water flow.

[0077] In some embodiments, the first water production module is a heating module, and the second water production module 250 is a cooling module. The heating module includes a tank and a heating device, which may include an electric heater. The cooling module includes a tank and a cooling device, which may include an evaporator or a semiconductor refrigerator.

[0078] like Figure 4 As shown, the first water production module is a heating module. The water inlet 241 of the first water production module 240 is located at the bottom of the module, and the water outlet 242 of the first water production module 240 is located at the top of the module. During operation, hot water rises while room-temperature water sinks. The water outlet 242 of the first water production module 240, located at the top of the module, maximizes the amount of hot water available, improving the effective utilization efficiency of the module.

[0079] like Figure 4 As shown, in this embodiment, the return water port 244 of the first water production module 240 is integrated with the water outlet 242 of the first water production module 240, so that the number of water ports on the first water production module is relatively small, and the number of pipelines can also be reduced.

[0080] exist Figure 4In the illustrated embodiment, the water inlet 241 of the first water production module 240 and the water outlet 243 of the first water production module 240 are integrated into a single water inlet, and are located at the bottom of the first water production module. The return water inlet 244 of the first water production module 240 and the water outlet 242 of the first water production module 240 are integrated into a single water inlet, and are located 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 via a first exhaust pipe 225. The first exhaust pipe 225 may be equipped with a damping plug with a relatively small aperture, for example, 0.3 mm to 0.5 mm.

[0081] like Figure 4 As shown, the water inlet 251 of the second water production module 250 is located at the upper portion of the second water production module 250, and the water outlet 252 of the second water production module 250 is connected to the lower portion of the second water production module 250. During operation of the second water production module 250, cold water sinks and room temperature water floats. By connecting the water outlet 252 of the second water production module 250 to the lower portion of the second water production module 250, cold water can be drawn to the greatest extent possible, thereby improving the actual and effective utilization efficiency of the second water production module 250.

[0082] exist Figure 4 In the illustrated embodiment, the water inlet 251 of the second water production module 250 is arranged at the top of the second water production module 250, the water outlet 252 of the second water production module 250 is arranged at the top of the second water production module 250 and extends to the lower part of the second water production module 250 through the water outlet pipe, the drain outlet 253 of the second water production module 250 is arranged at the bottom of the second water production module 250, and the drain outlet 253 of the second water production module 250 and the return water outlet 254 of the second water production module 250 are integrated into the same water outlet.

[0083] The water outlet 252 of the second water production module 250 is also connected to the top of the water tank 220 via a second exhaust pipe 226. The second exhaust pipe 226 can be equipped with a damping plug with a relatively small aperture, such as 0.3mm-0.5mm. Of course, other structures can also be used to achieve exhaust from the second water production module 250, such as providing an exhaust hole in the water pipe at the water outlet 252 of the second water production module 250. The exhaust hole can be 0.5mm-1.5mm, and the top cover of the second water production module 250 is provided with a separate exhaust cavity, and the exhaust hole is located within the exhaust cavity.

[0084] A small hole is added to the cold tank cover, and the solenoid valve is automatically opened to discharge air for a certain period of time.

[0085] like Figure 4As shown, in this embodiment, the return water port 254 of the second water production module 250 is integrated with the drain port 243 of the first water production module 240. In this way, the second water production module 250 has fewer water ports and can also reduce pipelines.

[0086] Of course, in other embodiments, the water inlet, water outlet, return water outlet and drain outlet may be independently provided on the water production module, which will not be described in detail here.

[0087] In some embodiments, as Figures 1-4 As shown, the wastewater outlet 102 of the water production equipment is equipped with a water stop device 500. In its natural state, the water stop device 500 blocks the wastewater outlet 102 of the water production equipment to prevent water leakage. When drainage is required, the wastewater outlet 102 can be conveniently opened by operating the water stop device 500. The water stop device 500 can be installed at the bottom of the front of the water production equipment, so that drainage can be achieved without moving the water production equipment.

[0088] In some embodiments, as Figure 7 and Figure 8 As shown, the switching valve 320 may be a solenoid valve, and the switching valve 320 may include: a control coil 324 , a valve core 325 , a valve bracket 326 and a valve seat 327 .

[0089] In which, the valve bracket 326 is connected to the valve seat 327, and a valve channel 518 is defined in the valve bracket 326 and the valve seat 327, wherein the valve seat 327 is provided with a first valve port 321 and a second valve port 322 connected to the valve channel 518, and the valve bracket 326 is provided with a second valve port 322 connected to the valve channel 518, the valve core 325 is movably mounted on the valve bracket 326, and the valve core 325 extends into the valve seat 327, and the control coil 324 is used to control the movement of the valve core 325.

[0090] like Figure 7 As shown, when the switching valve 320 is powered off, the first valve port 321 and the second valve port 322 are connected, that is, the third valve port 323 is cut off from the first valve port 321 in the natural state, so that the switching valve 320 can play a role in stopping water. Since the second valve port 322 is connected to the water-stop device 500, the second valve port 322 will not leak even if it is connected to the first valve port 321; Figure 8 As 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 connected. At this time, the first valve port 321 and the second valve port 322 are cut off.

[0091] In some embodiments, as Figure 5 and Figure 6 As shown, the water stopping device 500 includes a main housing 510 and a water stopping portion 520 .

[0092] The main shell 510 defines a channel 518 with both ends open. The first end of the channel 518 is connected to the water outlet of the water production module, and the second end of the channel 518 is connected to the wastewater outlet 102 of the water production equipment. When the channel 518 is in a connected state, the wastewater outlet 102 of the water production equipment is opened to achieve drainage.

[0093] The water stopper 520 is movably mounted on the main housing 510 , and the water stopper 520 can selectively cut off both ends of the channel 518 .

[0094] like Figure 5 As shown, in the natural state, the water stop 520 cuts off both ends of the channel 518, so that the wastewater outlet 102 is blocked; Figure 6 As shown, by moving the water stop portion 520, the two ends of the channel 518 can be connected, that is, the wastewater outlet 102 is opened.

[0095] In some embodiments, as Figure 5 As shown, the main housing 510 includes an upper cover 511 , a main pipe 515 and a sealing member 517 .

[0096] 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. The top wall of the upper cover 511 is provided with a through hole 514. The upper cover 511 is disposed outside the main body 515, and the main body 515 is connected to the through hole 514. The water stop 520 is movably mounted on the main body 515, and a 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 wastewater outlet 102 of the water production equipment. 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 wastewater outlet 102 of the water production equipment.

[0097] In this way, through the covering structure of the upper cover 511 and the main body 515, and the sealing of the sealing member 517, the main shell 510 is easy to form and has good sealing performance.

[0098] In some embodiments, as Figure 5 As shown, the top wall of the upper cover 511 is provided with an inner tube 512 protruding toward the inner side of the upper cover 511, the inner tube 512 is connected to the through hole 514, the main body 515 is sleeved on the outside of the inner tube 512, the seal 517 is bent, and a part of the seal 517 is clamped between the inner circumferential wall of the main body 515 and the outer circumferential wall of the inner tube 512, and the other part of the seal 517 is clamped between the end of the main body 515 and the top wall of the upper cover 511.

[0099] In this way, the peripheral wall of the upper cover 511, the main body 515 and the inner tube 512 form a three-layer sleeve structure, and the bent seal 517 realizes sealing in the axial and radial directions. The main shell 510 has good sealing performance and is not easy to leak water.

[0100] In some embodiments, as Figure 5 As shown, the top wall of the upper cover 511 is provided with an outer tube 513 protruding toward the outside of the upper cover 511, and the outer tube 513 is connected to the through hole 514. The outer tube 513 is equivalent to a joint for assembling the main body 515 and the pipeline.

[0101] The upper cover 511, the inner tube 512, and the outer tube 513 can be formed as one body. The inner diameter of the inner tube 512 is larger than that 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, thereby improving the reliability of the main housing 510.

[0102] In some embodiments, as Figure 5 As shown, the inner peripheral wall of the main body 515 is provided with an inwardly protruding support portion 516 , which defines a flow hole 519 . The support portion 516 may be annular, and the flow hole 519 is formed in the middle of the support portion 516 .

[0103] like Figure 5 As shown, the water stop portion 520 includes a guide column 521 , a water stop plug 522 and an elastic member 523 .

[0104] The guide column 521 passes through the circulation hole 519, and the guide column 521 and the circulation hole 519 are loosely matched. The outer diameter of the guide column 521 is smaller than the aperture of the circulation hole 519, and an annular gap is formed between the guide column 521 and the circulation hole 519, which is used for drainage.

[0105] The water stop plug 522 is connected to the guide column 521, and the sealing surface of the water stop plug 522 is suitable for completely covering the flow hole 519. When the sealing surface of the water stop plug 522 is in contact with the support part 516, the flow hole 519 can be covered, the flow hole 519 is blocked, and the water stop device 500 blocks the wastewater outlet 102; when the sealing surface of the water stop plug 522 is separated from the support part 516, the two ends of the through hole 514 are connected through the flow hole 519.

[0106] The elastic member 523 is elastically connected between the guide column 521 and the support portion 516 . In a natural state, the elastic member 523 is used to force the sealing surface of the water stopper 522 to abut against the support portion 516 .

[0107] In some embodiments, as Figure 5As shown, the side of the support portion 516 facing the sealing surface may be provided with a sealing boss 516a. This is annular and, when the sealing surface of the water stopper 522 is in contact with the sealing boss 516a, covers the flow hole 519, thereby blocking the flow hole 519. The contact area between the sealing surface of the water stopper 522 and the sealing boss 516a is smaller than when the sealing surface of the water stopper 522 is in direct contact with the support portion 516. Given a constant elastic force provided by the elastic member 523, the pressure between the sealing surface of the water stopper 522 and the sealing boss 516a is greater, resulting in greater elastic deformation of the water stopper 522 and a more effective seal.

[0108] In some embodiments, as Figure 5 As shown, the water-stopping device 500 further includes a drain pipe (not shown) and a push rod 530. The drain pipe is connected to the main body 515. The push rod 530 is installed in the drain pipe and is used to stop the guide column 521 to deform the elastic member 523 until the sealing surface of the water-stopping plug 522 is separated from the support portion 516.

[0109] In actual use, the push rod 530 is used to push away the guide column 521, so that the sealing surface of the water stopper 522 can be separated from the support part 516. When the push rod 530 is released, the sealing surface of the water stopper 522 and the support part 516 are automatically fitted together under the elastic force of the elastic member 523.

The return water port 254 of the second water production module 250 is connected to the water inlet 221 of the water tank 220 through a circulation control valve 307 and a circulation water pipe 306 .

[0122] The drain port 243 of the first water production module 240 is connected to the wastewater outlet 102 of the water production equipment through the first drain control valve 304 , and the drain port 253 of the second water production module 250 is connected to the wastewater outlet 102 of the water production equipment through the second drain control valve 305 .

[0123] The water production equipment can be provided with a switching valve 320, and the cut-off and conduction functions of the circulation control valve 307 can be replaced by the switching valve 320.

[0136] Reference below Figure 9 and Figure 10 The control method of the water production equipment provided by the embodiment of the present invention is described.

[0141] Step 620: Based on the drainage instruction, the water inlet control valve 303 is controlled to be closed, and the drainage control valve is controlled to be opened.

[0142] After the water inlet control valve 303 is closed, water can be prevented from continuing to enter the water tank 220, and the water discharge control valve is opened for water discharge.

[0143] Step 630: Control the water pump 230 to be turned on for the target time and then turned off, and keep the drainage control valve in the open state until the drainage is completed.

[0144] In other words, the water pump 230 is first turned on for the target time. At the target time, the water pump 230 can drain the water from 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. After the target time, the water pump 230 is turned off, and the water in the water production module is discharged through the drain outlet again.
