Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more particularly to a drinking water device. Background Technology

[0002] With the growing demand for healthy drinking water and coffee culture, users have significantly increased their need for multifunctional integrated devices that not only meet functional requirements but also take into account space utilization efficiency.

[0003] Currently, water purification, coffee making, and drinking water functions are usually achieved by separate devices. Standalone refrigerated water dispensers only provide cold water. During the refrigeration process, the local temperature of the cold water tank is prone to continuously dropping below the freezing point, resulting in icing. Icing not only reduces the effective water storage volume but also increases the heat exchange resistance, weakens the refrigeration efficiency, and leads to increased energy consumption.

[0004] Therefore, it is urgent to solve the technical problem of ice formation in the cold water tanks of drinking water equipment. Summary of the Invention

[0005] This invention provides a drinking device to solve the technical problem of ice formation in the cold water tank of a drinking device.

[0006] To achieve the above objectives, the present invention provides a drinking device, comprising:

[0007] A heat purification module, comprising a water purification module for filtering raw water;

[0008] A refrigeration module is connected to the downstream end of the water purification module. The refrigeration module includes a first liquid storage container, a refrigeration circulation unit, a circulation pump, and a temperature equalization circuit. The first liquid storage container has a first water storage chamber inside. The refrigeration circulation unit is used to cool the water stored in the first water storage chamber. Both ends of the temperature equalization circuit are connected to the first liquid storage container. The circulation pump is set in the temperature equalization circuit so that the water stored in the first water storage chamber circulates through the temperature equalization circuit.

[0009] The drinking water device provided in this application, during operation, first introduces raw water into the heat purification module, where it is filtered to form purified water. The purified water is then transported to the cooling module and temporarily stored in the first liquid storage container. The cooling circulation unit continuously exchanges heat with the water stored in the first liquid storage container to remove heat from the water, thus cooling the water in the first storage chamber. Simultaneously, since both ends of the temperature equalization circuit are connected to the first liquid storage container, and a circulation pump is installed in the temperature equalization circuit, the pump drives the water stored in the first storage chamber to circulate through the temperature equalization circuit, forming a directional forced circulation. This prevents stagnation of the water in the first liquid storage container, which could lead to localized excessively low temperatures and freezing, thus improving the uniformity of water temperature and cooling efficiency. This effectively prevents the water in the first liquid storage container from freezing and reducing its effective storage volume.

[0010] In one possible implementation, the circulation pump has a pump inlet and a pump outlet, the pump inlet being connected to the bottom region of the first liquid storage container and the pump outlet being connected to the upper region of the first liquid storage container, so that, under the action of the circulation pump, water in the bottom region of the first liquid storage container flows to the upper region of the first liquid storage container through the equalization circuit.

[0011] In one possible implementation, the refrigeration module further includes a support frame, and the refrigeration cycle unit includes a compressor, a condenser, a throttling device, an evaporator, and refrigeration piping. The compressor, the condenser, the throttling device, and the evaporator are connected in series via the refrigeration piping shown. The compressor and the condenser are both mounted on the support frame, and a buffer is provided between the compressor and the support frame. The evaporator is located in the first water storage chamber.

[0012] In one possible implementation, the bracket includes a bottom panel, a top panel, and a connecting plate connecting the bottom panel and the top panel, with a lower mounting cavity formed between the bottom panel and the top panel, the compressor located in the lower mounting cavity, and the first liquid storage container and the condenser both disposed on the side of the top panel facing away from the lower mounting cavity.

[0013] The compressor has a support leg at its bottom, which is connected to the bottom panel by fasteners, and the buffer abuts against the support leg and the bracket.

[0014] In one possible implementation, the drinking device further includes a coffee module and a housing, the coffee module being connected to the downstream end of the water purification module and arranged in parallel with the cooling module, the housing having a receiving cavity, and the water purification module, the coffee module and the cooling module being arranged sequentially in the receiving cavity along a first direction;

[0015] The bracket is connected to the inner bottom wall of the housing by fasteners, and a vibration damping element is provided between the bracket and the inner bottom wall of the housing.

[0016] In one possible implementation, the cooling module further includes a cooling fan for dissipating heat from the condenser.

[0017] In one possible implementation, the drinking device further includes a ventilation fan disposed within the accommodating cavity, the ventilation fan having a downwardly facing air outlet, the ventilation fan being used to ventilate the accommodating cavity.

[0018] In one possible implementation, a temperature detection device is also provided inside the first liquid storage container;

[0019] And / or, the first liquid storage container is further provided with a first water level detection element and a second water level detection element. The first water level detection element is arranged at intervals below the second water level detection element along the height direction. The first water level detection element and the second water level detection element respectively detect the lowest liquid level and the highest liquid level of the first liquid storage container.

[0020] And / or, the first liquid storage container is also provided with a sterilization unit.

[0021] In one possible implementation, the drinking device further includes a second liquid storage container connected between the water purification module and the coffee module, the second liquid storage container being used to supply water to the coffee module.

[0022] In one possible implementation, the heat dissipation module further includes a heating pipeline connected in parallel with the coffee module at the downstream end of the second liquid storage container. The heating pipeline includes a first heating element for heating the water flow passing through the first heating element.

[0023] The drinking water device provided in this application has a circulating pump inlet connected to the bottom area of ​​the first liquid storage container. The cooled water in the bottom area of ​​the first liquid storage container enters the temperature equalization circuit under the suction of the circulating pump, and flows back to the upper area of ​​the first liquid storage container under the pressurized delivery of the pump outlet. This allows the low-temperature water that would normally accumulate locally at the bottom of the first liquid storage container to be continuously lifted and redistributed to the upper area of ​​the first liquid storage container, mixing with the relatively warm water in the first liquid storage container. This creates a bottom-up circulating flow inside the first liquid storage container, effectively dispersing the cold air, achieving full-area water flow, eliminating dead zones, and maintaining a relatively uniform temperature field in the water in the first liquid storage container. This improves cooling efficiency, effectively reduces the problem of freezing due to local overcooling during continuous cooling, and helps improve the stability of the outlet water temperature and the long-term reliability of the drinking water device.

[0024] The drinking device provided in this application achieves a double soft connection because the buffer abuts between the compressor's support legs and the bracket, and the vibration damping component is arranged between the bracket and the inner bottom wall of the outer casing. When the compressor is running, the buffer absorbs part of the compressor's vibration energy and compensates for the assembly gap, thereby suppressing the transmission of the compressor's high-frequency vibration to the bracket. The vibration damping component can attenuate the vibration transmitted to the outer casing, reducing the noise and vibration generated by the whole machine.

[0025] The drinking water device provided in this application, by designing the water purification module, coffee module, and refrigeration module as independent detachable units, not only meets the space requirements for embedded installation but also facilitates later maintenance and functional combination adjustments. This allows the drinking water device to integrate water purification, heating, refrigeration, and coffee preparation functions into one unit, avoiding the redundant installation of multiple independent devices, ensuring the stability of coffee taste and drinking water quality, and meeting daily drinking water and coffee preparation needs.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] Drinking water equipment is commonly used in home kitchens, office pantries, and commercial beverage supply locations to meet needs such as filtered drinking water, hot and cold water supply, and pre-production water supply for beverage preparation. In these scenarios, drinking water equipment typically needs to be connected to raw water and sequentially complete processes such as filtration, storage, cooling, and dispensing. Therefore, it places high demands on the connectivity of the water system, the stability of water storage, and the temperature uniformity during the cooling process.

[0049] In related technologies, the raw water is usually purified by a filter first, and then the purified water is transported to a storage container. A refrigeration mechanism is used to cool the water in the storage container, thereby providing cold water to the user or providing a source of cold water for subsequent beverage preparation.

[0050] However, in embedded or compact installations, the water flow within the storage container is often insufficient, easily leading to localized low-temperature zones near the cooling area. This results in uneven water distribution and temperature stratification. Especially when cooling is continuous, icing may occur in these subcooled areas, affecting not only the overall heat exchange efficiency within the container but also causing fluctuations in the outlet water temperature and reducing the user experience.

[0051] Meanwhile, localized icing can further hinder water circulation, concentrating cold energy in a few areas and making it difficult to distribute evenly, thus affecting the long-term stability of the equipment. For applications requiring continuous water supply, this makes it difficult for the equipment to simultaneously achieve stable cooling, uniform water output, and reliable operation.

[0052] In view of this, the present invention provides a drinking device that improves the water flow distribution in the liquid storage container while cooling the water stored in the first water storage chamber through a uniform temperature circuit, thereby providing a reliable basis for stable cooling and uniform water output.

[0053] The drinking device provided in the embodiments of the present invention will now be described with reference to the accompanying drawings.

[0054] refer to Figure 1 and Figure 2 As shown, this application provides a drinking water device, including: a heat purification module 10 and a cooling module 30. The heat purification module 10 includes a water purification module 40, which is used to filter raw water. The cooling module 30 is connected to the downstream end of the water purification module 40. (Refer to...) Figure 3 and Figure 4 As shown, the refrigeration module 30 includes a first liquid storage container 31, a refrigeration cycle unit 32, a circulation pump 33, and a temperature equalization circuit 34. The first liquid storage container 31 has a first water storage chamber 311 inside. The refrigeration cycle unit 32 is used to cool the water stored in the first water storage chamber 311. Both ends of the temperature equalization circuit 34 are connected to the first liquid storage container 31. The circulation pump 33 is set in the temperature equalization circuit 34 so that the water stored in the first water storage chamber 311 circulates through the temperature equalization circuit 34.

[0055] refer to Figure 1 and Figure 4 As shown, in the drinking water device provided in this application, during operation, raw water first enters the heat purification module 10 and is filtered by the water purification module 40 to form purified water. The purified water is then transported to the cooling module 30 and temporarily stored in the first liquid storage container 31. The cooling circulation unit 32 continuously exchanges heat with the stored water in the first liquid storage container 31 to remove heat from the water, thus cooling the water in the first water storage chamber 311. At the same time, since both ends of the temperature equalization circuit 34 are connected to the first liquid storage container 31, and the circulation pump 33 is set in the temperature equalization circuit 34, the operation of the circulation pump 33 drives the water stored in the first water storage chamber 311 to circulate through the temperature equalization circuit 34, forming a directional forced circulation. This prevents the water stored in the first liquid storage container 31 from stagnating, which would cause local low temperatures and freezing, thus improving the uniformity of water temperature and cooling efficiency. This effectively prevents the water in the first liquid storage container 31 from freezing and occupying the effective water storage volume.

[0056] refer to Figure 1 and Figure 2 As shown, the heat purification module 10 is located in the upstream area of ​​the whole machine's water supply path and is connected to the external water inlet through a pipeline. The downstream end of the heat purification module 10 is connected to the water inlet of the cooling module 30, so that the purified water can be transported to the cooling module 30 along a predetermined path.

[0057] The water purification module 40 is located in the first flow path after the raw water enters the heat purification module 10. The raw water is tap water. The inlet of the water purification module 40 is connected to an external water source, and the outlet of the water purification module 40 is connected to the first liquid storage container 31 of the cooling module 30. The water purification module 40 is used to filter and purify the raw water, removing suspended impurities, odor components, and pollutants that affect drinking quality, thereby ensuring that the water entering the cooling module 30 has a consistent initial state.

[0058] In one possible implementation method, refer to Figure 2 As shown, the heat purification module 10 also includes a mounting frame 11, and the water purification module 40 is disposed on the mounting frame 11. The water purification module 40 includes a first filter element 41 and a second filter element 42 that are interconnected, and the first filter element 41 and the second filter element 42 are respectively disposed on the two side walls of the mounting frame 11.

[0059] In one possible implementation, the first filter element 41 can be a PCB filter element located on the front side wall of the mounting bracket 11. The PCB filter element integrates a triple filtration structure of polypropylene fiber (PP) cotton, granular activated carbon, and compressed activated carbon, serving as a pre-treatment filter element for the entire machine. The outer PP cotton layer blocks large suspended particles such as sediment, rust, and colloids in the water, the middle granular activated carbon adsorbs residual chlorine and pungent odors in tap water, and the inner compressed activated carbon deeply adsorbs trace amounts of organic matter and discolored impurities.

[0060] In one possible implementation, the second filter element 42 can be a reverse osmosis (RO) membrane filter element, located on the left or right side wall of the mounting bracket 11. The RO membrane filter element utilizes high-pressure reverse osmosis sieving technology to efficiently remove scale, heavy metal ions, bacteria, colloids, and soluble salts from the water, producing clean, pure water with low TDS.

[0061] refer to Figure 1 and Figure 4 As shown, the cooling module 30 is connected downstream of the water purification module 40. The cooling module 30 is used to temporarily store the purified water obtained by the water purification module 40 in the first liquid storage container 31, and to cool the water stored in the first liquid storage container 31 by means of the cooling circulation unit 32. At the same time, the water body is circulated through the temperature equalization circuit 34 and the circulation pump 33 to maintain a relatively uniform temperature distribution in the first liquid storage container 31.

[0062] In one possible implementation, the first liquid storage container 31 can adopt a rectangular box, a rounded corner box, or a cylindrical tank structure. The first liquid storage container 31 can be made of food-grade plastic, a thin-walled metal container, or a composite material. The inner surface of the first liquid storage container 31 can be treated to prevent scaling or corrosion. A first water storage cavity 311 is formed inside the first liquid storage container 31. The first water storage cavity 311 is used to contain the water to be cooled and completes heat exchange under the action of the refrigeration cycle unit 32.

[0063] The side wall, bottom wall or partial wall of the first liquid storage container 31 is arranged corresponding to the heat exchange end of the refrigeration cycle unit 32. The first liquid storage container 31 is also provided with a water inlet connected to the water purification module 40 and a circulation interface connected to the temperature equalization circuit 34.

[0064] The function of the refrigeration cycle unit 32 is to remove heat from the water in the first liquid storage container 31 through a refrigeration medium circulation or heat exchange process, thereby lowering the water temperature to a predetermined range. The refrigeration cycle unit 32 can be electrically connected to the controller of the entire drinking water device, so that the controller can control the refrigeration cycle unit 32 to achieve start / stop control and temperature regulation.

[0065] Both ends of the isothermal circulation loop 34 are connected to the first liquid storage container 31. The isothermal circulation loop 34 is used to guide the water circulation within the first liquid storage container 31, thereby reducing local low-temperature zones and temperature stratification. The inlet and outlet of the isothermal circulation loop 34 are connected to the two circulation ports of the first liquid storage container 31 through pipes, allowing the water to circulate across regions under the guidance of the isothermal circulation loop 34.

[0066] In one possible implementation, the temperature equalization circuit 34 can be a coiled flow channel, a serpentine flow channel, or a structure with an internal flow guide. The temperature equalization circuit 34 can be made of food-grade plastic tubing, silicone tubing, metal tubing, or a composite flexible tubing. The connection between the temperature equalization circuit 34 and the first liquid storage container 31 can be secured by welding, snap-fitting, quick-connect fittings, or hose clamping. The diameter of the temperature equalization circuit 34 is smaller than the main body dimension of the first liquid storage container 31. The inner diameter of the temperature equalization circuit 34 should be compatible with the diameters of the two circulation ports of the first liquid storage container 31. The length and number of bends of the temperature equalization circuit 34 can be set according to the volume of the first liquid storage container 31 and the circulation resistance to achieve stable circulation under acceptable pressure drop.

[0067] In one possible implementation method, refer to Figure 1 and Figure 4 As shown, the circulating pump 33 can be arranged in the middle of the temperature equalization circuit 34 or near the inlet of the temperature equalization circuit 34. The circulating pump 33 applies suction and transportation to the water in the first liquid storage container 31, so that the water continuously circulates along the temperature equalization circuit 34, and mixes the water in different areas of the first liquid storage container 31 during the circulation process.

[0068] In one possible implementation, the circulating pump 33 may be a centrifugal pump, diaphragm pump, or magnetic pump.

[0069] In one possible implementation, the circulation pump 33 has a pump inlet 331 and a pump outlet 332. The pump inlet 331 is connected to the bottom region of the first liquid storage container 31, and the pump outlet 332 is connected to the upper region of the first liquid storage container 31, so that under the action of the circulation pump 33, water in the bottom region of the first liquid storage container 31 flows to the upper region of the first liquid storage container 31 through the temperature equalization circuit 34.

[0070] Since the pump inlet 331 of the circulating pump 33 is connected to the bottom area of ​​the first liquid storage container 31, the cooled water in the bottom area of ​​the first liquid storage container 31 enters the temperature equalization circuit 34 under the suction of the circulating pump 33, and flows back to the upper area of ​​the first liquid storage container 31 under the pressurized delivery of the pump outlet 332. This causes the low-temperature water that originally tended to accumulate locally at the bottom of the first liquid storage container 31 to be continuously lifted and redistributed to the upper area of ​​the first liquid storage container 31, mixing with the relatively warm water in the first liquid storage container 31. This forms a bottom-up circulating flow inside the first liquid storage container 31, thereby effectively dispersing the cold energy, realizing the flow of water throughout the entire area, eliminating dead zones in the water flow, and enabling the water in the first liquid storage container 31 to maintain a relatively uniform temperature field, improving the cooling efficiency and effectively reducing the problem of freezing caused by local overcooling during continuous cooling.

[0071] In addition, the circulating pump 33 makes the water flow continuously through the temperature equalization circuit 34, which can also enhance the convective heat transfer effect inside the first liquid storage container 31, and make the cooling capacity of the refrigeration cycle unit 32 more evenly distributed to the entire first water storage chamber 311, thereby helping to improve the stability of the outlet water temperature and the reliability of the long-term operation of the drinking equipment.

[0072] In one possible implementation, the outer wall of the first liquid storage container 31 is covered with an insulation layer to improve its insulation effect and save energy. The insulation layer can be, for example, insulation cotton, which has good thermal insulation properties, effectively reduces heat conduction, and prevents heat loss, thereby achieving energy saving, insulation, and antifreeze effects.

[0073] In one possible implementation method, refer to Figure 4 and Figure 5 As shown, the refrigeration module 30 also includes a bracket 35, and the refrigeration cycle unit 32 includes a compressor 321, a condenser 322, a throttling device 323, an evaporator 324, and a refrigeration pipeline 325. The compressor 321, the condenser 322, the throttling device 323, and the evaporator 324 are connected in series through the refrigeration pipeline 325 shown. The compressor 321 and the condenser 322 are both mounted on the bracket 35. A buffer 36 is provided between the compressor 321 and the bracket 35. The evaporator 324 is located in the first water storage chamber 311.

[0074] In one possible implementation, the bracket 35 provides a stable mounting base for components such as the compressor 321 and condenser 322, facilitating the arrangement of the refrigeration piping 325 and subsequent inspection and maintenance. The bracket 35 can be a sheet metal bracket, a profile bracket, or an injection-molded reinforced bracket, preferably made of steel plate, aluminum alloy, or high-strength engineering plastic.

[0075] The compressor 321, condenser 322, throttling device 323 and evaporator 324 are connected in series through refrigeration pipe 325 to form a closed refrigeration circuit, so that the refrigerant can complete the compression, condensation, throttling and evaporation processes in sequence.

[0076] The compressor 321 serves as the power source for the refrigeration cycle, driving the refrigerant to circulate. The condenser 322 releases the heat carried by the high-temperature and high-pressure refrigerant to the external environment. The throttling device 323 reduces the pressure and temperature of the refrigerant. The evaporator 324 exchanges heat with the water in the first water storage chamber 311 to cool the water in the first water storage chamber 311, thereby achieving cooling of the water.

[0077] In one possible implementation, the throttling device 323 can be a capillary tube with an inner diameter between 0.6 mm and 1.2 mm, for example, 0.8 mm or 1 mm. The capillary tube is a slender copper tube with a very small inner diameter, serving to throttle and distribute the flow. The throttling device 323 can also be an electronic expansion valve, etc.

[0078] In one possible implementation, the refrigeration cycle unit 32 further includes a dryer 326 connected in series in the refrigeration line 325 between the condenser 322 and the throttling device 323. The dryer 326 is used to dry the liquid refrigerant, remove water, and filter impurities.

[0079] In other possible implementations, the cooling cycle unit 32 may employ a semiconductor cooling structure.

[0080] By setting a buffer 36 between the compressor 321 and the bracket 35, which can be connected by fasteners such as screws and bolts, the buffer 36 can effectively absorb the vibration and noise generated when the compressor 321 is working, reduce the transmission of the vibration generated when the compressor 321 is working to the bracket 35, thereby achieving the effect of noise reduction and vibration reduction.

[0081] In one possible implementation, the buffer 36 may be a rubber pad, a silicone pad, or an elastic polyurethane pad, or it may be replaced by a spring damper, a rubber column, or a composite damping structure.

[0082] refer to Figure 4 As shown, the evaporator 324 is disposed in the first water storage chamber 311, and can be directly immersed in the bottom area of ​​the first water storage chamber 311, so that the evaporator 324 is more immersed in the water in the first water storage chamber 311, thereby increasing the heat exchange contact area with the water.

[0083] The circulating pump 33 draws low-temperature water from the bottom of the first liquid storage container 31 to the top, and forces it to flow through the temperature equalization circuit 34. This ensures that the low-temperature water near the evaporator 324 is fully mixed with the high-temperature water at the top, preventing localized low-temperature water accumulation near the evaporator 324 and thus avoiding freezing. Simultaneously, the continuous agitation of the water in the first liquid storage container 31 enhances the lateral and longitudinal convection heat transfer, which helps improve refrigeration efficiency, maintain water temperature uniformity, and extend the service life of the drinking water equipment.

[0084] In one possible implementation, the evaporator 324 can be installed inside the first water storage chamber 311 via a support, fixing clip, or sealing through structure, maintaining a predetermined distance from the wall of the first water storage chamber 311 to avoid affecting water circulation. The heat exchange area of ​​the evaporator 324 should be matched with the volume of the first water storage chamber 311 to achieve uniform cooling within a reasonable cooling time and without hindering the circulation of water.

[0085] In one possible implementation, the evaporator 324 may be a coil, plate, or sleeve structure, typically using copper, aluminum, or stainless steel composite tubes.

[0086] In one possible implementation, the refrigeration piping 325 may be made of copper, aluminum or composite metal and bendable according to the refrigerant flow rate and the available space.

[0087] refer to Figure 4 and Figure 5 As shown, during operation, after the compressor 321 starts, it compresses the refrigerant, causing the high-temperature, high-pressure gaseous refrigerant to enter the condenser 322 along the refrigeration pipe 325 and liquefy outwards. The liquid refrigerant then continues along the refrigeration pipe 325, passing through the throttling device 323 to reduce its pressure and temperature, becoming a low-temperature, low-pressure gas-liquid mixture. This gas-liquid mixture continues along the refrigeration pipe 325 into the evaporator 324, where it absorbs heat from the water in the first water storage chamber 311. The gas-liquid mixture gradually evaporates into a gaseous state, and the heat from the water in the first water storage chamber 311 is transferred to the refrigerant, achieving continuous cooling of the water in the first water storage chamber 311. The gaseous refrigerant, after evaporation in the evaporator 324, then enters the compressor 321 again, starting the next refrigeration cycle.

[0088] The drinking device provided in this application has a short heat exchange path and sufficient contact with the water because the evaporator 324 is located in the first water storage chamber 311. This can improve the cooling efficiency.

[0089] The drinking device provided in this application has a compressor 321 connected to the bracket 35 via a buffer 36 for vibration isolation. This can significantly reduce the impact of the compressor 321's operating vibration on the bracket 35 and the drinking device as a whole, and reduce problems such as pipe loosening, increased noise, and local fatigue damage caused by vibration.

[0090] The drinking water equipment provided in this application has its compressor 321 and condenser 322 centrally mounted on the bracket 35, which facilitates a compact modular layout, saves installation space, and makes the assembly and maintenance of the whole machine easier.

[0091] In one possible implementation method, refer to Figure 3 and Figure 4 As shown, the bracket 35 includes a bottom panel 351, a top panel 352, and a connecting plate 353 connecting the bottom panel 351 and the top panel 352. A lower mounting cavity 354 is formed between the bottom panel 351 and the top panel 352. The compressor 321 is located in the lower mounting cavity 354. The first liquid storage container 31 and the condenser 322 are both disposed on the side of the top panel 352 facing away from the lower mounting cavity 354. The bottom of the compressor 321 has a support leg 3211, which is connected to the bottom panel 351 by fasteners. The buffer 36 abuts against the support leg 3211 and the bracket 35.

[0092] In one possible implementation, the bracket 35 includes a bottom panel 351, a top panel 352, and a connecting plate 353 connecting the bottom panel 351 and the top panel 352, wherein the top end of the connecting plate 353 is connected to the top panel 352, and the bottom end of the connecting plate 353 is connected to the bottom panel 351.

[0093] In one possible implementation, the connection between the top end of the connecting plate 353 and the top panel 352 includes, but is not limited to, fastener connection, snap-fit ​​connection, welding connection, etc., and the connection between the bottom end of the connecting plate 353 and the bottom panel 351 includes, but is not limited to, fastener connection, snap-fit ​​connection, welding connection, etc.

[0094] In one possible implementation, the bottom panel 351 may be a horizontal or generally horizontal plate, the top panel 352 may be a horizontal or generally horizontal plate, and at least part of the connecting plate 353 may be an upright plate.

[0095] In one possible implementation method, refer to Figure 3 and Figure 4 As shown, the circulation pump 33 can be arranged on the top panel 352. The pump inlet 331 of the circulation pump 33 is located at the lowest point of the first liquid storage container 31, which reduces the negative pressure required for the circulation pump 33 to operate, thus helping to ensure the overall lifespan of the circulation pump 33. This is because as long as the first liquid storage container 31 is powered on, the circulation pump 33 will continue to operate regardless of whether the user draws cold water from the first liquid storage container 31, so the longer the lifespan of the circulation pump 33, the better. In addition, the fact that the pump inlet 331 of the circulation pump 33 is located at the lowest point of the first liquid storage container 31 can also ensure that all the water in the first liquid storage container 31 can circulate, without any dead zones in the water flow, thereby improving the uniformity of water temperature.

[0096] When the circulating pump 33 is working, it transports the water in the bottom area of ​​the first liquid storage container 31 to the top area of ​​the first liquid storage container 31 through the temperature equalization circuit 34, ensuring that the water in the first liquid storage container 31 is always in a flowing state. This can prevent the local water temperature in the first liquid storage container 31 that is in contact with the evaporator 324 from being too low and causing freezing. This avoids the problem of uneven water temperature in the first liquid storage container 31 and inconsistent temperature when the user takes water.

[0097] The compressor 321 has a support leg 3211 at its bottom, which is used to transfer the weight and working load of the compressor 321 to the bottom panel 351. The support leg 3211 can be connected to the bottom panel 351 by fasteners, such as screws, bolts or rivets. The support leg 3211 and the bottom panel 351 can be provided with positioning holes or threaded holes for the fasteners to pass through for connection, thereby improving assembly accuracy.

[0098] The thickness of the buffer 36 is less than the height of the support leg 3211. The compression of the buffer 36 can be matched according to the weight, speed and vibration amplitude of the compressor 321 to provide appropriate elastic support while ensuring the support strength.

[0099] The vibrations generated during the operation of compressor 321 are first transmitted to bottom panel 351 via support leg 3211, and then elastically dissipated and attenuated by buffer 36 between support leg 3211 and bracket 35. Some vibrations are absorbed by buffer 36, while the remaining vibrations are dispersed by bracket 35. Since top panel 352, connecting plate 353 and bottom panel 351 form a layered frame with a certain rigidity, the vibrations of compressor 321 are not easily directly coupled to first liquid storage container 31 and condenser 322, thus helping to reduce the operating noise of refrigeration cycle unit 32.

[0100] refer to Figure 3 and Figure 4 As shown, the condenser 322 and the first liquid storage container 31 are both arranged on the upper surface of the top panel 352, which makes the arrangement of the refrigeration cycle unit 32 more compact. Under the premise of ensuring the stable installation of the compressor 321, the transmission of vibration to the first liquid storage container 31 and the condenser 322 is reduced, the overall machine operation is improved, and the reliability and stability of the drinking water equipment under continuous refrigeration conditions are enhanced.

[0101] In the drinking device provided in this application, the refrigeration cycle unit 32 and the first liquid storage container 31 are fixed by the bracket 35, so that the refrigeration module 30 is assembled into an independent module. After pre-assembly and testing on the auxiliary assembly line, the whole unit is assembled into the drinking device. This saves production processes and time, and also facilitates subsequent maintenance.

[0102] In one possible implementation method, refer to Figure 1 and Figure 2 As shown, the drinking device also includes a coffee module 20 and a housing 80. The housing 80 has a receiving cavity 81, and the heat dissipation module 10, coffee module 20, and cooling module 30 are arranged sequentially in the receiving cavity 81 along a first direction; Reference Figure 6 and Figure 7 As shown, the bracket 35 is connected to the inner bottom wall of the housing 80 by fasteners, and a vibration damping element 37 is provided between the bracket 35 and the inner bottom wall of the housing 80.

[0103] The drinking water device provided in this application has a housing cavity 81 within its outer casing 80. The housing cavity 81 provides assembly and operating space for the heating module 10 and the cooling module 30. The heating module 10 and the cooling module 30 are arranged sequentially within the housing cavity 81 along a first direction, which allows the internal water channels, control lines, and cooling components to be arranged according to a predetermined route, thereby reducing pipeline intersections and improving the overall space utilization rate, and facilitating disassembly and maintenance.

[0104] First Direction Reference Figure 2 The arrow X in the image indicates the left-right direction of the drinking device in this example, so that the heat dissipation module 10, coffee module 20 and cooling module 30 are arranged from left to right, making it convenient for users to operate them separately at the front of the drinking device.

[0105] The heat dissipation module 10, the coffee module 20, and the cooling module 30 are arranged sequentially in the accommodating cavity 81 along the first direction, forming a relatively regular straight or quasi-straight structure in the length direction. This achieves reasonable structural coordination, which helps to shorten the intersection path of internal pipelines, reduce assembly interference, prevent redundancy in the overall layout, and improve the maintenance efficiency of each functional module.

[0106] The outer shell 80 can be a box-type, cabinet-type, or an embedded shell suitable for embedding in a cabinet. The material can be metal sheet, engineering plastic, or a metal and plastic composite structure. The accommodating cavity 81 can be a single cavity structure, or it can be partially divided by a partition to accommodate the heat dissipation module 10 and the cooling module 30 respectively.

[0107] The outer shell 80 can be a one-piece bent metal shell, an injection molded engineering plastic shell, or a composite shell assembled from a metal frame and an outer panel. The accommodating cavity 81 can be a closed cavity with an inspection door.

[0108] refer to Figure 6 As shown, since the bracket 35 is connected to the inner bottom wall of the housing 80 by fasteners, and a vibration damping element 37 is provided between the bracket 35 and the inner bottom wall of the housing 80, the vibration damping element 37 isolates and buffers the vibration from the compressor 321 after the bracket 35 is installed.

[0109] In one possible implementation, the damping element 37 can be a rubber pad, elastic bushing, or foam pad, or it can be a silicone damping block, spring isolator, or composite damping element; the fasteners can be screws, bolts, clips, or rivets to adapt to different assembly processes and disassembly requirements. The thickness and compression of the damping element 37 need to be controlled within a range that can effectively absorb vibration without affecting the installation stability of the bracket 35.

[0110] The drinking device provided in this application achieves a double soft connection because the buffer 36 abuts between the support leg 3211 of the compressor 321 and the bracket 35, and the vibration damping member 37 is arranged between the bracket 35 and the inner bottom wall of the outer casing 80. When the compressor 321 is running, the buffer 36 absorbs part of the vibration energy of the compressor 321 and compensates for the assembly gap, thereby suppressing the transmission of high-frequency vibration of the compressor 321 to the bracket 35. The vibration damping member 37 can attenuate the vibration transmitted to the outer casing 80, thereby reducing the noise and vibration generated by the whole machine.

[0111] In one possible implementation, the damper 37 can be configured as a sheet, column, or block to ensure a stable buffering effect during equipment startup, steady-state operation, and shutdown.

[0112] When the drinking device is running, the mechanical vibration generated by the cooling module 30 is transmitted to the vibration damping component 37 through the bracket 35. The vibration damping component 37 can absorb and attenuate some of the vibration, reduce the vibration transmitted to the outer casing 80, and enable the heat dissipation module 10 and the cooling module 30 to work in a relatively stable mechanical environment. This helps to reduce the noise of the whole machine, reduce the fatigue and loosening of pipes and connectors, and improve the structural reliability and user comfort during long-term operation.

[0113] In one possible implementation, the coffee module 20 is connected downstream of the water purification module 40 and is arranged in parallel with the refrigeration module 30.

[0114] The coffee module 20 is used to heat and transport the water purified by the water purification module 40, and to complete the coffee extraction or brewing function. Since the coffee module 20 and the refrigeration module 30 are connected in parallel, the purified water can be diverted to the refrigeration branch or the coffee making branch according to different water needs, so that the drinking device can simultaneously supply cold water and make coffee without interfering with each other.

[0115] After the coffee module 20 and the refrigeration module 30 are connected in parallel, they can share the purified water source output by the water purification module 40. In actual use, the flow direction can be switched to meet the different needs of refrigeration water intake and coffee preparation in terms of flow rate, pressure and timing.

[0116] In one possible implementation method, refer to Figure 4 As shown, the cooling module 30 also includes a cooling fan 327, which is used to dissipate heat from the condenser 322.

[0117] The cooling fan 327 drives airflow continuously or intermittently, enhancing the convective heat transfer effect around the condenser 322, thereby improving the heat release efficiency of the refrigerant in the condenser 322, preventing the accumulation of heat generated by the condenser from causing the compressor 321 to overheat and shut down, and reducing the temperature rise of the condenser 322 during operation.

[0118] The cooling fan 327 can be installed on the top panel 352 of the bracket 35 and arranged relative to the condenser 322. The air outlet of the cooling fan 327 faces the heat dissipation area of ​​the condenser 322, so that the airflow covers the effective heat exchange surface of the condenser 322 as much as possible, and ensures that the airflow output by the cooling fan 327 can directionally sweep across the fins or heat exchange surface of the condenser 322 to form a local forced convection environment.

[0119] In one possible implementation, the cooling fan 327 can be an axial fan or a centrifugal fan.

[0120] refer to Figure 4 and Figure 5 As shown, during operation, when the refrigeration module 30 starts and enters the refrigeration running state, the compressor 321 drives the refrigerant to circulate within the refrigeration pipe 325. The refrigerant releases heat to the outside at the condenser 322. At this time, the cooling fan 327 works simultaneously and continuously disturbs the air around the condenser 322, allowing the heat on the surface of the condenser 322 to be carried away by the airflow more quickly, thereby reducing the surface temperature of the condenser 322 and improving the heat exchange conditions of the refrigeration cycle unit 32. Because the condenser 322 dissipates heat more fully, the refrigerant can more stably complete the heat release during the condensation stage, and the entire refrigeration cycle operates more smoothly.

[0121] In one possible implementation method, refer to Figure 6 As shown, the drinking device also includes a ventilation fan 82, which is disposed in the accommodating cavity 81. The ventilation fan 82 has a downward-facing air outlet and is used to ventilate the accommodating cavity 81.

[0122] When the drinking device is embedded, it is in a relatively closed environment. As the working time of the refrigeration module 30 increases, the temperature in the closed environment will rise, which will easily increase the power consumption of the refrigeration module 30. In order to ensure the cooling effect and efficiency of the first liquid storage container 31, the ventilation fan 82 drives the air in the accommodating cavity 81 to form a directional flow and increase the air velocity. The ventilation fan 82 can timely exhaust the hot air accumulated in the accommodating cavity 81, and at the same time introduce the outside air with a lower temperature to improve the thermal environment inside the accommodating cavity 81, reduce the local temperature rise inside the accommodating cavity 81, and assist in the dissipation of the heat generated by the heat dissipation module 10 and the refrigeration module 30 during operation. This solves the problem that the drinking device is difficult to dissipate heat in a closed embedded environment, which leads to increased energy consumption and decreased cooling efficiency.

[0123] The ventilation fan 82 can be arranged in the accommodating cavity 81 near the upper part or near the heat source concentration area. The ventilation fan 82 has a downward-facing air outlet, which allows the airflow to be discharged in the side-down direction and is connected to the external exhaust channel, bottom opening or air guide structure on the outer shell 80 of the drinking equipment, thereby preventing hot air from lingering inside the accommodating cavity 81.

[0124] In one possible implementation, the ventilation fan 82 can be an axial flow fan or a centrifugal fan. The air outlet of the ventilation fan 82 can be configured as a straight cylindrical opening, a flat opening, or an irregularly shaped opening with guide vanes.

[0125] In one possible implementation, the air outlet of the ventilation fan 82 can be directed downwards by using an injection-molded air guide hood, a sheet metal bending-formed duct shell, or a flexible duct, in order to improve ventilation efficiency and reduce airflow backflow.

[0126] refer to Figure 2 , Figure 6 and Figure 7 As shown, when the drinking water device is working, the ventilation fan 82 continuously carries the heat generated in the accommodating cavity 81 by the operation of the heat dissipation module 10, the cooling module 30, and other electrical components into the surrounding air. The ventilation fan 82 directs the hot air out through the downward-facing air outlet, making it difficult for the heat accumulated in the upper part to circulate and stagnate in the accommodating cavity 81. At the same time, fresh air from outside enters the accommodating cavity 81 under the action of pressure difference, thereby forming a continuous convection ventilation process. This makes the temperature inside the accommodating cavity 81 more uniformly distributed, and the heat around the condenser 322 and other heat-generating devices is more easily carried away, thereby reducing the problem of local overheating and mitigating the adverse effects of high temperature accumulation on cooling efficiency and the lifespan of electrical components.

[0127] In one possible implementation method, refer to Figure 8 and Figure 9 As shown, the front panel of the housing 80 is provided with a water outlet assembly 85, which includes a water outlet 851 and a coffee outlet 852. The water outlet 851 is used to output purified or heated drinking water. Cold water, hot water and room temperature water share one water outlet 851. The coffee outlet 852 is used to output coffee.

[0128] In one possible implementation, the front panel of the housing 80 is provided with a display screen 86, which can be used to display the operating status information of the drinking device.

[0129] In one possible implementation method, refer to Figure 8 and Figure 9 As shown, the outer casing 80 is connected to a front door 87. Opening the front door 87 reveals the water tray 25, waste bin 26, bean hopper 21, and a cover 12 that covers the front of the first filter element 41. When the cover 12 is open, it is convenient to remove and replace the first filter element 41. The front door 87 has a partially transparent area, allowing users to view the water outlet component 85 of the drinking device through this transparent area, which also enhances the aesthetics of the appearance.

[0130] In one possible implementation, the front door 87 is made of a transparent material, such as glass. To prevent the blown hot air from encountering the front door 87 and forming condensation, the ventilation fan 82 can be installed on the front panel of the drinking device, so that the air blown by the ventilation fan 82 is discharged downwards, reducing the problem of the air blown by the ventilation fan 82 contacting the front door 87 and forming condensation.

[0131] The drinking device provided by this invention can be relatively large in size, with a length of 595mm, a height of 455mm, and a depth of 445mm. (Reference) Figure 2 As shown, by modularizing the heating module 10, coffee module 20, and cooling module 30, they can be individually assembled in the assembly workshop. After passing the test, they are then transferred into the outer shell 80 of the drinking equipment, avoiding the need for frequent handling and moving of the entire machine during the reinstallation and testing process, making installation and maintenance more convenient.

[0132] refer to Figure 1 and Figure 2 As shown, in different usage scenarios, users can selectively retain the coffee module 20 and the refrigeration module 30. When cold water is needed, the refrigeration module 30 receives purified water and completes cooling, storage, or ice production output. When coffee is needed, the coffee module 20 receives purified water for extraction, brewing, or steam-related processing.

[0133] For example, in some scenarios, retaining the heating module 10 and the coffee module 20 while removing the cooling module 30 allows the drinking device to provide purified water, room temperature water, hot water, and coffee, thus meeting daily needs. In other scenarios, retaining both the heating module 10 and the cooling module 30 allows the drinking device to provide purified water, room temperature water, hot water, and cold water, simultaneously meeting the needs for various drinking water temperatures.

[0134] In one possible implementation method, refer to Figure 1 and Figure 4 As shown, a temperature detection element 312 is also provided inside the first liquid storage container 31. The temperature detection element 312 can convert the physical quantity of temperature into a measurable electrical signal.

[0135] Temperature detection element 312 is used to detect the water temperature in the first liquid storage container 31. Temperature detection element 312 acquires the temperature information of the water stored in the first liquid storage container 31 in real time and outputs the corresponding detection signal to the controller of the drinking device so that the controller of the drinking device can adjust the operating status of the refrigeration cycle unit 32 accordingly.

[0136] In one possible implementation, the temperature sensing element 312 may be located on the inner bottom wall or near the bottom of the first liquid storage container 31, or it may be located near the heat exchange area where the evaporator 324 is located, in order to improve the response sensitivity to changes in water temperature.

[0137] In one possible implementation, the temperature sensing element 312 can be a sealed mounting structure that penetrates the wall of the first liquid storage container 31, or it can be fixed to the inner wall of the first liquid storage container 31 by a snap fastener, with the temperature sensing end of the temperature sensing element 312 in contact with the water as much as possible.

[0138] In one possible implementation, the temperature sensing element 312 may be a thermistor or a temperature probe, and the external package of the temperature sensing element 312 may be a stainless steel package, a resin package, or a glass package to meet the requirements of long-term immersion in water and low-temperature environments.

[0139] The temperature sensor 312 can continuously or intermittently monitor the temperature changes in the first liquid storage container 31, enabling the controller of the drinking water device to determine the cooling intensity based on the actual water temperature and adjust the working state of the circulation pump 33 or the refrigeration circulation unit 32 in a timely manner, thus helping to maintain the stability of the outlet water temperature. When the temperature sensor 312 detects that the temperature in the first liquid storage container 31 is higher than the preset temperature, the controller of the drinking water device controls the compressor 321 to start working. The compressor 321 drives the refrigerant to circulate in the refrigeration pipeline 325. When the refrigerant passes through the evaporator, it absorbs heat, thereby cooling the water in the first liquid storage container 31.

[0140] In one possible implementation method, refer to Figure 1 and Figure 4 As shown, the first liquid storage container 31 is also provided with a first water level detection element 313 and a second water level detection element 314. The first water level detection element 313 is arranged at intervals below the second water level detection element 314 along the height direction. The first water level detection element 313 and the second water level detection element 314 respectively detect the lowest liquid level and the highest liquid level of the first liquid storage container 31.

[0141] In one possible implementation, the evaporator 324 is disposed in the first water storage chamber 311 and is located below the first water level detection element 313. Even when the water level in the first water storage chamber 311 is at the lowest water level, the evaporator 324 can be completely surrounded by water, with sufficient heat exchange contact area. The evaporator 324 will never burn dry without water, thus avoiding the problem of high temperature damage.

[0142] The first water level detection element 313 and the second water level detection element 314 determine the water storage volume by identifying the water level status at different heights, and prevent idling when the liquid level is too low, and prevent overflow or accidental water replenishment when the liquid level is too high.

[0143] The first water level detection element 313 and the second water level detection element 314 are arranged at intervals along the height direction of the first liquid storage container 31. The first water level detection element 313 is arranged at intervals below the second water level detection element 314 along the height direction. The first water level detection element 313 can be set at a position close to the lowest safe liquid level, and the second water level detection element 314 can be set at a position close to the highest allowable liquid level.

[0144] The first water level detection element 313 and the second water level detection element 314 can be directly fixed to the inner wall of the first liquid storage container 31, or sealed and assembled to the wall of the first liquid storage container 31 through a reserved installation hole, or arranged on a suspension frame inside the first liquid storage container 31.

[0145] In some embodiments, the outer periphery of the first water level detection element 313 and the second water level detection element 314 may be a shell made of stainless steel, engineering plastic or water-resistant resin material. The distance between the first water level detection element 313 and the second water level detection element 314 is usually matched with the effective height of the first water storage cavity 311, thereby forming obvious lower limit judgment and upper limit judgment areas, which facilitates the controller of the drinking water device to perform hierarchical control.

[0146] The drinking device provided in this application, by also providing a first water level detection element 313 and a second water level detection element 314 inside the first liquid storage container 31, can accurately identify changes in liquid level during the process of water inlet, cooling and water outlet of the first liquid storage container 31, thereby avoiding the decrease in cooling efficiency due to water shortage or overflow due to overfilling. It also facilitates coordinated control with the circulation pump 33 and the cooling circulation unit 32 to maintain the first water storage chamber 311 within a reasonable working liquid level range.

[0147] In one possible implementation, a sterilization unit 315 is also provided inside the first liquid storage container 31. The sterilization unit 315 is used to reduce the growth of microorganisms in the first water storage chamber 311, so as to improve the hygiene and safety and storage stability of drinking water.

[0148] In one possible implementation, the sterilization unit 315 may be located on the bottom wall of the first water storage chamber 311 or near the circulation interface connected to the temperature equalization circuit 34, so that the water can be treated whether the water is flowing or stored statically.

[0149] In some embodiments, the sterilization unit 315 can be an ultraviolet (UV) light source, which inhibits the reproduction of microorganisms through light irradiation, thereby playing a role in sterilization and bacteriostasis, and thus creating a bacteriostatic environment in the water.

[0150] By also providing a sterilization unit 315 inside the first liquid storage container 31, the first liquid storage container 31 can simultaneously inhibit bacterial growth and biofilm formation during the process of storing purified water and cooling it, thereby helping to maintain water quality hygiene during long-term operation.

[0151] In one possible implementation method, refer to Figure 1 As shown, the drinking device also includes a second liquid storage container 90, which is connected between the water purification module 40 and the coffee module 20, and is used to supply water to the coffee module 20.

[0152] The second liquid storage container 90 is located between the water purification module 40 and the coffee module 20. It can be connected to the outlet of the water purification module 40 through a water supply pipeline and to the inlet of the coffee module 20 through another water supply pipeline to form a continuous water supply pipeline. The second liquid storage container 90 is used to temporarily store purified water from the water purification module 40 and to provide a stable water source to the coffee module 20 when it is working.

[0153] The second liquid storage container 90 can be made into a water tank, a buffer tank, an intermediate water storage chamber, or a water storage box with liquid level control. The second liquid storage container 90 can be made of food-grade plastic, stainless steel, glass, or composite materials.

[0154] The volume of the second liquid storage container 90 can be set according to the single or continuous preparation needs of the coffee module 20. For example, the volume of the second liquid storage container 90 can be the buffer capacity required for the continuous preparation of multiple cups.

[0155] In one possible implementation, the second liquid storage container 90 is equipped with an ultraviolet germicidal lamp 94, which destroys the nucleic acid of microorganisms in the water by ultraviolet irradiation, thereby achieving water sterilization and disinfection.

[0156] In one possible implementation method, refer to Figure 1 As shown, the heat dissipation module 10 also includes a heating pipe 50, which is connected in parallel with the coffee module 20 at the downstream end of the second liquid storage container 90. The heating pipe 50 includes a first heating element 52, which is used to heat the water flowing through the first heating element 52.

[0157] In the drinking device provided in this application, the heating pipe 50 is used to provide hot or warm water to the drinking device, so that the drinking device has the function of hot water supply and meets the differentiated needs for water temperature in different drinking scenarios. The first heating element 52 can quickly exchange hot water flow when water flows through it, thereby realizing instant heating or near-instant heating.

[0158] The heating pipe 50 and the coffee module 20 are connected in parallel to the downstream end of the second liquid storage container 90. This means that the purified water output from the second liquid storage container 90 can enter either the heating pipe 50 or the coffee module 20, thereby achieving separate switching between hot water supply and coffee preparation based on the same water source. The heating pipe 50 can work in conjunction with the coffee module 20 to adapt to different water usage modes such as hot drinks and coffee making.

[0159] In one possible implementation, the heating pipe 50 can be arranged as a straight section, a coiled section, or a segmented flow channel, depending on the internal space of the drinking equipment and the heating requirements.

[0160] The heating pipe 50 and the downstream end of the second liquid storage container 90 can be connected by a pipe joint, quick-connect joint or hose sleeve, and can share the same water source with the coffee module 20 before being connected in parallel for diversion.

[0161] In one possible implementation, the first heating element 52 can be a thick-film tube heating element with an internal stainless steel pipe and spiral baffles. An insulating layer and a silver-palladium heating circuit are sintered on the outside of the pipe. A temperature probe is installed on the pipe wall. The first heating element 52 is covered with heat-insulating cotton, and water connectors are provided at both ends to achieve complete water-electricity isolation and rapid heat exchange. When water flows through the stainless steel pipe with spiral baffles, the silver-palladium heating circuit on the outer wall is energized to generate heat. The heat is conducted to the pipe wall through the insulating layer, where it fully exchanges heat with the flowing water inside the pipe. The spiral structure can prolong the heat exchange contact time. Combined with real-time temperature control by the temperature probe, instantaneous heating of the water is achieved.

[0162] refer to Figure 1 As shown, during operation, the purified water in the second liquid storage container 90 can enter the coffee module 20 or the heating pipe 50 according to the water usage mode. When hot water is needed, the water flowing through the heating pipe 50 is heated when it passes through the heating zone where the first heating element 52 is located, and then outputs to the water outlet 851 at the set temperature to achieve hot water use. In the coffee preparation mode, the water can enter the coffee module 20 through a parallel path to complete the coffee making, and then be output through the coffee outlet 852.

[0163] Because the heating pipe 50 is connected in parallel with the coffee module 20 at the downstream end of the second liquid storage container 90, it reduces the need for redundant water supply structures and facilitates the selection of hot water supply or coffee making process according to instructions. The heating pipe 50 provides a stable hot water output and improves the overall functionality and water adaptability of the machine through parallel flow splitting, making the water flow heating path clearer and helping to improve the stability of hot water output and ease of use.

[0164] The drinking water device provided in this application, by independently designing the water purification module 10, coffee module 20, and cooling module 30 as detachable units, not only meets the space requirements for embedded installation but also facilitates later maintenance and functional combination adjustments. This allows the drinking water device to integrate water purification, heating, cooling, and coffee preparation functions into one unit, avoiding redundant installation of multiple independent devices, ensuring the stability of coffee taste and drinking water quality, and meeting daily drinking water and coffee preparation needs.

[0165] In one possible implementation method, refer to Figure 1As shown, a hot water flow control pump 51, a water-vapor separator 53, and a hot water check valve 54 are also connected in series in the heating pipeline 50. The hot water flow control pump 51 can accurately regulate and stabilize the output water flow. The water-vapor separator 53 separates steam and liquid water in the pipeline, and the hot water check valve 54 can prevent hot water backflow and ensure stable one-way water delivery.

[0166] refer to Figure 1 As shown, the water purification module 40 is also equipped with an inlet solenoid valve 43, a booster pump 44, a flushing solenoid valve 45, a first water quality detector 46, and a second water quality detector 47. The inlet solenoid valve 43 manages the water flow into the water purification module 40. The first and second water quality detectors 46 and 47 can be TDS (Total Dissolved Solids) probes, monitoring the total dissolved solids (TDS) values ​​of the inlet and outlet water in real time. The TDS values ​​are expressed in ppm / mg / L. By comparing the difference between the inlet and outlet water values ​​measured by the first and second water quality detectors 46 and 47, the system accurately identifies RO membrane leakage and filtration efficiency degradation, promptly reminding users to replace the filter cartridge. The flushing solenoid valve 45 controls the flow of wastewater into the sewer. When the flushing solenoid valve 45 is open, the wastewater produced by the water purification module 40 can be discharged into the sewer. When the drinking water device is closed, the flushing solenoid valve 45 is closed to prevent sewer water or odors from flowing upwards into the drinking water device, improving hygiene.

[0167] Working principle of water purification module 40: Municipal tap water enters the water purification module 40 of the drinking water equipment. The water flow first passes through the first filter element 41, which is a PCB filter element. The first filter element 41 includes pre-activated carbon 411 and post-activated carbon 412. After the water flow passes through the pre-activated carbon 411 of the PCB filter element, it is pressurized by the booster pump 44. The pressurized water flow passes through the second filter element 42 to become pure water. Finally, the water flow passes through the post-activated carbon 412 of the PCB filter element to complete the water purification process. The purified water is then used by subsequent modules. The pre-activated carbon 411 can be granular activated carbon, and the post-activated carbon 412 can be compressed activated carbon.

[0168] When a user needs room temperature water, they press the water dispensing button on the drinking device. The button is electrically connected to the device's controller. The controller detects the user's water request, opens the inlet solenoid valve 43, and starts the booster pump 44. Municipal tap water enters the water purification module 40 of the drinking device. The water first passes through the first filter element 41, which is a PCB filter element. After being filtered by the pre-activated carbon 411 of the PCB filter element, the water is pressurized by the booster pump 44. Then, the pressurized water is filtered into pure water through the second filter element 42. Next, the pure water is filtered by the post-activated carbon 412 of the PCB filter element, and after passing through the second flow meter 61 and the room temperature water solenoid valve 62, it flows out through the outlet 851, thus enabling the dispensing of room temperature water.

[0169] When water is drawn from the external faucet and water dispenser, the pressure of the high-pressure switch 71 connected to the water intake pipeline of the external faucet and water dispenser decreases. The high-pressure switch 71 is electrically connected to the controller of the drinking water equipment. The controller detects the decrease in pressure of the high-pressure switch 71 and outputs a control signal to the water purification module 40. The water purification module 40 starts to purify the water. The purified water flows through the first one-way valve 72 and the high-pressure switch 71 to the external faucet and water dispenser, realizing water intake from the external faucet and water dispenser.

[0170] When a user needs hot water, the user presses the corresponding hot water dispensing button on the drinking device. The controller of the drinking device controls the hot water one-way valve 54 to open and controls the hot water flow control pump 51 and the first heating element 52 to work. The water flowing through the first heating element 52 is heated by the first heating element 52. After the water is heated to a suitable temperature, it completes the vapor-liquid separation through the water vapor separation box 53. The clean hot water after treatment finally flows out from the water outlet 851, completing the hot water dispensing.

[0171] During the hot water dispensing process, when the low water level detector 91 in the second liquid storage container 90 detects that the water level is too low, the controller activates the water purification module 40 to replenish water to the second liquid storage container 90. Water continues to replenish the second liquid storage container 90 until the high water level detector 92 detects that the liquid level in the second liquid storage container 90 has reached the maximum level. At this point, the water purification module 40 stops operating, thus ceasing the replenishment of water to the second liquid storage container 90. A second water replenishment solenoid valve 93 is connected between the inlet end of the second liquid storage container 90 and the downstream end of the water purification module 40. When the second water replenishment solenoid valve 93 opens, the purified water from the water purification module 40 can flow into the second liquid storage container 90, replenishing the second liquid storage container 90.

[0172] In one possible implementation, the coffee module 20 includes a frame and a bean hopper 21. The bean hopper 21 is disposed on the frame. The coffee module 20 is also connected to a coffee grinder 22, a coffee extractor 23, a vibratory pump 241, a pressure regulator 242, and a first flow meter 243. The coffee grinder 22 and the coffee extractor 23 may be fixed to the frame. One side of the frame may be connected to the mounting bracket 11 by fasteners.

[0173] In one possible implementation, the coffee module 20 also includes a second heating element 24, which may be a thick film tube heating element.

[0174] When a user needs coffee, they press the coffee selection button on the drinking device. The controller of the drinking device receives the signal to make coffee. First, the coffee beans stored in the bean hopper 21 flow into the coffee grinder 22, which grinds the coffee beans into coffee powder. The coffee powder flows into the coffee extractor 23, which compresses and compacts the ground coffee powder. Then, the vibration pump 241 draws a certain amount of water from the second liquid storage container 90. The water flowing out of the second liquid storage container 90 is transported through a pipeline. The pipeline is equipped with a first flow meter 243, a vibration pump 241, and a pressure regulating valve 242, which respectively measure, pressurize, and stabilize the water flow. The treated water flows into the second heating element 24 to be heated to form usable hot water, which then flows into the coffee extractor 23 through the pressure relief valve 244. The extracted coffee flows out through the coffee spout 852.

[0175] A drip tray 25 is placed below the coffee spout 852 to collect water droplets that may accidentally fall from the coffee spout 852. After extraction, the coffee grounds remaining in the coffee extractor 23 are deposited into the grounds bin 26.

[0176] When a user needs milk foam or hot milk, they press the milk foam or hot milk making button on the drinking device. The controller of the drinking device receives the milk foam or hot milk making signal. The milk tank 291 inside the drinking device stores milk and is connected to the milk frother 29 through a pipeline. The milk tank 291 outputs milk to the milk frother 29. The vibration pump 241 draws a certain amount of water from the second liquid storage container 90. The first flow meter 243, the vibration pump 241, and the pressure regulating valve 242 installed in the pipeline measure, pressurize, and regulate the water flow, respectively. The treated water flows into the second heating element 24 to complete the heating and form usable hot water. The high-temperature water vapor passes through the water outlet valve 27 and the reversing valve 28 before entering the milk frother 29. On the one hand, the high temperature of the steam rapidly heats the milk inside the milk frother 29. On the other hand, the steam flow carries air into the milk, continuously impacting and stirring it to froth the liquid milk into dense and delicate milk foam. The produced milk foam is directly used to make milk coffee drinks such as lattes and cappuccinos.

[0177] When the water level detector 91 in the second liquid storage container 90 detects that the water level is too low during the process of making milk foam, heating milk, or making coffee, the controller controls the water purification module 40 to start and the second water replenishment solenoid valve 93 to open, replenishing water to the second liquid storage container 90. The water purification module 40 stops working and stops replenishing water to the second liquid storage container 90 after the high water level detector 92 in the second liquid storage container 90 detects that the liquid level in the second liquid storage container 90 has reached the maximum water level.

[0178] When a user needs to use cold water, the user presses the cold water button on the drinking device. The controller of the drinking device receives the signal, and the cold water flow control pump 39 turns on. The cold water in the first liquid storage container 31 is drawn out by the cold water flow control pump 39 and flows out from the water outlet 851, thus realizing the use of cold water.

[0179] When the first water level detector 313 detects that the water level in the first liquid storage container 31 is too low during the cold water intake process, the controller controls the water purification module 40 to start and the first water replenishment solenoid valve 38 to open. The purified water from the water purification module 40 enters the first liquid storage container 31 to replenish the first liquid storage container 31. The water purification module 40 stops working and stops replenishing the first liquid storage container 31 until the second water level detector 314 in the first liquid storage container 31 detects that the liquid level in the first liquid storage container 31 has reached the maximum water level.
