[0050] Combination Figures 1 to 3 This application provides a drinking water device 1, which can be a water dispenser or a kitchen water purifier, etc.

[0051] The drinking water device 1 includes a housing 10, a cooling component 20, a water circuit component 30, and an electrical control component 40. The housing 10 forms the exterior surface of the drinking water device 1 and provides installation space for the cooling component 20, the water circuit component 30, and the electrical control component 40. A receiving cavity can be formed inside the housing 10, and the cooling component 20, the water circuit component 30, and the electrical control component 40 are all disposed within the receiving cavity. The cooling component 20 provides cooling capacity to the water circuit component 30, the water circuit component 30 circulates water, and the electrical control component 40 performs overall control of the cooling component 20, the water circuit component 30, and other components.

[0052] For example, the water system assembly 30 includes a cold tank 31 and a piping structure 32. The piping structure 32 includes a room temperature water pipe 34, a cold water pipe 35, and an instant hot water pipe 36. Understandably, the piping structure 32 also has an inlet 336 and an outlet. A room temperature water flow path is formed within the room temperature water pipe 34, with one end connected to a water source and the other end connected to the outlet. The piping structure 32 also includes a room temperature water valve 341 connected to the room temperature water pipe 34 for controlling the on / off state of the room temperature water pipe 34. Understandably, the user can obtain room temperature water from the outlet by opening the room temperature water valve 341. A cold water tank 31 is installed on a cold water pipeline 35 and has a cold water inlet 336 and a cold water outlet. The cold water pipeline 35 connects the inlet 336 and the cold water inlet 336 of the cold water tank 31, and also connects the cold water outlet 31 and the cold water outlet. The pipeline structure 32 also includes a cold water inlet valve 351 and a cold water outlet valve 352. The cold water inlet valve 351 controls the flow between the inlet 336 and the cold water inlet 336 of the cold water tank 31, and the cold water outlet valve 352 controls the flow between the cold water outlet 31 and the cold water outlet. Understandably, when there is cold water in the cold water tank 31, the user can draw cold water from the outlet by opening the cold water outlet valve 352. An instant heating pipeline 36 connects the inlet 336 and the outlet. The pipeline structure 32 also includes a hot water valve, which controls the flow of the instant heating pipeline 36. Users can obtain hot water from the outlet by simply turning on the hot water valve.

[0053] In the water circuit component 30, the ambient temperature water pipe 34, the cold water pipe 35, and the instant hot water pipe 36 can share a common inlet 336, or they can each have their own inlet 336. Correspondingly, the outlets of the ambient temperature water pipe 34, the cold water pipe 35, and the instant hot water pipe 36 can be one or more, which is not limited here.

[0054] The refrigeration assembly 20 provides cooling capacity to the cold tank 31 for producing chilled water. Optionally, the refrigeration assembly 20 includes a compressor 21, a condenser, and an evaporator, which are connected in sequence. Specifically, the compressor 21 operates and undergoes processes such as suction, compression, discharge, condensation (liquefaction), and throttling, ultimately vaporizing at a low temperature in the evaporator. The evaporator can be located inside the cold tank 31; the low-temperature evaporator can lower the water temperature inside the cold tank 31 to produce chilled water.

[0055] Understandably, the electrical control component 40 is electrically connected to all components of the aforementioned refrigeration component 20 and to on / off control components such as the ambient temperature water valve 341 and hot water valve in the water circuit component 30, in order to control the on / off state of the water circuit and the operating mode.

[0056] In related technologies, the number of integrated components in the drinking water device 1 is increasing, and the water circuit and circuit coexist in the device, which poses a safety hazard of water leakage affecting the circuit.

[0057] Please combineFigure 2 To solve the above problems, in this embodiment of the application, the cold tank 31 can be arranged on the side, above or below the refrigeration component 20 without limitation, while the pipeline structure 32 is arranged on one side of the refrigeration component 20 in the circumferential direction, and the electronic control component 40 is arranged on the other side of the refrigeration component 20, so as to be spaced apart from the pipeline structure 32.

[0058] For ease of explanation, the definitions are as follows: Figure 2 The front-back, up-down, and left-right directions are shown. In this embodiment, the outer casing 10 includes a front panel 15, a rear cover 16, a left side panel 17, a right side panel 18, a top cover 19, and a base 11 connected together. The cooling component 20 is mounted on the base 11, the piping structure 32 is mounted on the front side of the cooling component 20, and the electronic control component 40 is mounted on the rear side of the cooling component 20. By placing the piping structure 32 and the electronic control component 40 on different sides of the cooling component 20, and distributing them far apart within the outer casing 10, the water path and the electronic control are separated. Even if the piping structure 32 leaks, the dripping water is unlikely to come into contact with the electronic control component 40, thereby reducing or avoiding the impact of the water path on the electronic control component 40, reducing safety hazards, and improving the safety and reliability of the drinking water device 1.

[0059] In some embodiments of this application, the electronic control component 40 and the piping structure 32 are located on opposite sides of the cooling component 20. For example... Figure 2 The illustrated piping structure 32 is positioned at the front of the refrigeration component 20, and the electronic control component 40 is positioned at the rear of the refrigeration component 20. Alternatively, in other structural configurations, the piping structure 32 may be positioned on the left side of the refrigeration component 20, and the electronic control component 40 on the right side. This arrangement maximizes the distance between the electronic control component 40 and the piping structure 32, thereby reducing or eliminating the impact of the water circuit on the electronic control component 40 and improving the safety and reliability of the drinking water device 1. Furthermore, positioning the electronic control component 40 and the piping structure 32 on opposite sides of the refrigeration component 20 allows the center of gravity of each component of the drinking water device 1 to be closer to its own longitudinal axis, resulting in a more stable structure and contributing to a reduction in the size of the drinking water device 1.

[0060] Of course, in other embodiments, the electronic control component 40 and the pipeline structure 32 can also be arranged on adjacent sides of the refrigeration component 20. For example, the pipeline structure 32 can be arranged on the front side of the refrigeration component 20, while the electronic control component 40 can be arranged on the left, right or upper side of the refrigeration component 20. This can also separate the electronic control component 40 and the pipeline structure 32 to avoid water interference. No further limitations are made here.

[0061] Understandably, the ambient temperature water pipe 34, cold water pipe 35, and instant hot water pipe 36 in the piping structure 32 can be connected by water pipes. In another embodiment of this application, the piping structure 32 includes a water circuit board 33 and multiple on / off control components. The water circuit board 33 is generally plate-shaped, forming at least part of multiple flow paths such as the ambient temperature water pipe 34, cold water pipe 35, and instant hot water pipe 36. Multiple on / off control components are connected to the water circuit board 33, including the aforementioned ambient temperature water valve 341 and hot water valve. This embodiment uses an integrated water circuit board 33, which significantly reduces the number of pipes and joints, reduces the complexity of installation, improves assembly efficiency, and reduces the risk of leakage caused by improper pipe insertion or loose joints. In addition, the simple structure of the water circuit board 33 not only makes the internal structure of the drinking water device 1 neater and more aesthetically pleasing, but also facilitates maintenance and improves the reliability of the drinking water device 1.

[0062] The following explanation continues with the structural form of the pipeline structure 32, including the water circuit board 33:

[0063] Combination Figures 3 to 5 In some embodiments, the drinking device 1 further includes a first support 12, a second support 13, and a third support 14.

[0064] The first support 12 is connected to the base 11 and includes two sub-frames spaced apart in the front-to-back direction and a crossbeam connecting the two sub-frames. The cold tank 31 is connected to the crossbeam, and the cold tank 31 and the first support 12 also define an installation space for the refrigeration assembly 20. In this embodiment, the compressor 21 is located within the installation space, the condenser is located at the bottom or side of the compressor 21, and the cold tank 31 is located at the top of the compressor 21. This vertical distribution of the compressor 21 and the cold tank 31 makes the internal structure of the water drinking device 1 more compact, reduces the floor space occupied by the water drinking device 1, and improves space utilization. By placing the compressor 21 at the bottom, the center of gravity is lowered, reducing vibration and noise caused by the operation of the compressor 21, thus improving the user experience of the water drinking device 1.

[0065] The second bracket 13 is located on the front side of the first bracket 12. It can be directly connected to the base 11, connected to the first bracket 12, or connected to both the base 11 and the first bracket 12. The water channel plate 33 is mounted on the second bracket 13, and the water channel plate 33 is snap-fitted to the second bracket 13. This makes it easier to assemble and disassemble the water channel plate 33 and the second bracket 13, improving the efficiency of assembly and disassembly. Of course, the water channel plate 33 and the second bracket 13 can use other detachable connection methods such as bolt connection, or a combination of two or more connection methods such as bolt connection and snap-fit ​​connection, to make the fixation of the water channel plate 33 more secure. This embodiment of the application does not require this.

[0066] In one embodiment, multiple on / off control components, such as the ambient temperature water valve 341, the cold water inlet valve 351, the cold water outlet valve 352, and the hot water valve, are all connected to the side of the water circuit board 33 away from the refrigeration assembly 20. That is, the ambient temperature water valve 341, the cold water inlet valve 351, the cold water outlet valve 352, and the hot water valve are all connected to the front side of the water circuit board 33. After removing the front panel 15, the ambient temperature water valve 341, the cold water inlet valve 351, the cold water outlet valve 352, and the hot water valve can be seen, which facilitates the debugging and installation of multiple on / off control components and improves work efficiency.

[0067] Optionally, in this embodiment, the water outlet includes a first water outlet 337 and a second water outlet 338. The ambient temperature water pipe 34 and the cold water pipe 35 are connected to the first water outlet 337, and the hot water pipe 36 is connected to the second water outlet 338, thus distinguishing between hot and cold water outlets. This facilitates the water circuit layout of the water circuit board 33 and prevents accidental scalding of the user. To prevent cross-flow between ambient temperature water and cold water, the multiple on / off control components also include a one-way valve 354 connected to the cold water pipe 35, so that when cold water is not being used, the one-way valve 354 can prevent ambient temperature water from entering the cold water pipe 35.

[0068] Combination Figure 3 and Figure 6 In one embodiment, the multiple on / off control components also include a hot water pump 364 and a heating element 365. The hot water pump 364 is mounted on the base 11 and connected to the instant heating pipe 36, used to pump water from the inlet 336 to the second outlet 338. The heating element 365 is connected to the second bracket 13 and located between the water circuit board 33 and the cold tank 31, and is connected to the instant heating pipe 36 downstream of the hot water pump 364. Understandably, when the water pumped by the hot water pump 364 to the instant heating pipe 36 flows through the heating element 365, the heating element 365 heats the water in real time. Compared with the solution of using a hot tank to heat room temperature water, the heating method of the instant heating pipe 36 has higher heating efficiency. In this embodiment, the hot water pump 364 is mounted on the base 11 to reduce the impact of the vibration of the hot water pump 364 during operation on the second bracket 13 and improve the stability of the drinking water device 1.

[0069] Optionally, the heating element 365 can be a heating tube or a heating plate, and this application embodiment does not limit this.

[0070] The hot water valve includes an instant hot water inlet valve 361 and an instant hot water outlet valve 362. Both valves are connected to the side of the water circuit board 33 away from the refrigeration component 20. The instant hot water inlet valve 361 controls the connection between the instant hot water pipe 36 and the inlet 336, while the instant hot water outlet valve 362 controls the connection between the instant hot water pipe 36 and the second outlet 338. When hot water is needed, both the instant hot water inlet valve 361 and the instant hot water outlet valve 362 are open. When hot water is not needed, the instant hot water outlet valve 362 is closed, and the instant hot water inlet valve 361 can also be closed.

[0071] Furthermore, in one embodiment, the multiple on / off control components also include a pressure reducing valve 363. The pressure reducing valve 363 is connected upstream of the heating element 365 to the instant heating pipe 36, and is connected to the side of the water circuit board 33 away from the cooling assembly 20. By using the pressure reducing valve 363, the water pressure in the instant heating pipe 36 can be reduced, thereby reducing the water flow rate in the instant heating pipe 36, so that the heating element 365 can heat the flowing water into hot water, which can improve the accuracy of water temperature control by the drinking water device 1.

[0072] Combination Figure 3 and Figure 7 In one embodiment, the multiple on / off control components also include a cold water pump 353, which is connected to the cold tank 31 and the cold water pipeline 35, and is used to pump water from the cold tank 31 to the cold water pipeline 35. In this embodiment, the cold water pump 353 is connected to the front side of the second bracket 13, and the water circuit board 33 is also connected to the front side of the second bracket 13. The water circuit board 33 is arranged to avoid the cold water pump 353, so that the cold water pump 353 can be exposed from the side of the water circuit board 33 away from the refrigeration component 20, so as to facilitate the installation and maintenance of the cold water pump 353 and improve the efficiency of disassembly and assembly.

[0073] The third bracket 14 is located on the rear side of the first bracket 12. It can be directly connected to the base 11, connected to the first bracket 12, or connected to both the base 11 and the first bracket 12. The electronic control component 40 is snap-fitted to the side of the third bracket 14 away from the refrigeration component 20 for easy assembly and disassembly. Of course, the electronic control component 40 and the third bracket 14 can also use other detachable connection methods such as bolt connection, or a combination of two or more connection methods such as bolt connection and snap-fit ​​connection to make the electronic control component 40 more secure. This application embodiment does not require this.

[0074] In this embodiment, the first support 12, the second support 13, and the third support 14 can be made of metal or plastic. For example, the first support 12 can be made of metal to ensure structural strength, while the second support 13 and the third support 14 can be made of plastic to facilitate production and reduce the weight of the drinking water device 1.

[0075] In this embodiment of the application, the above-mentioned cooling component 20, water circuit component 30, electronic control component 40 and housing 10 are integrated into the main unit 1a of the water drinking device 1. The housing 10 is provided with a water inlet 151 and at least one water outlet 151, so that the water inlet 336 is exposed at the water inlet 151 and the water outlet is exposed at the water outlet 151, which facilitates the connection of the main unit 1a with other pipelines, or facilitates water inlet and drainage.

[0076] Some water storage components within the water drinking device 1, such as the cold tank 31, need to be connected to the air. However, in some related technologies, such as under-sink water drinking devices 1, the environment in which the water storage components are connected to the air is poor, for example, if they are located inside a kitchen cabinet, which can cause the water in the storage components to have an odor, affecting the user experience.

[0077] To solve the above problems, please combine... Figures 8 to 11 The drinking device 1 in this embodiment further includes a water outlet structure 50, which can be a faucet or other device capable of discharging water. The main unit 1a has an air outlet 339, which communicates with the hot water tank or other water storage structures within the drinking device 1 to balance air pressure and prevent structural damage. The water outlet structure 50 is located above the main unit 1a; for example, it can be installed on a kitchen stove or washbasin, partially exposed above the countertop for easy access by the user.

[0078] The water outlet structure 50 has a vent 54 and a drain hole 55. The drinking device 1 also includes a water supply pipe and a gas supply pipe. The water supply pipe connects the water outlet and the drain hole 55, and the gas supply pipe connects the gas outlet 339 and the vent 54. Thus, the vent 54 and the drain hole 55 of the water outlet structure 50 are connected to the gas outlet 339 and the water outlet respectively through pipes. The water storage device in the drinking device 1 is connected to the atmosphere at the water outlet structure 50. The position of the water outlet structure 50 is higher than that of the main unit 1a. Since water needs to be discharged at the water outlet structure 50, there is less obstruction around the water outlet structure 50, making it less likely for odors to remain and resulting in higher air quality. In this embodiment, the water storage device in the drinking device 1 can be connected to the higher quality atmosphere, which can reduce or prevent odorous air from entering the drinking device 1 and affecting the water, thus preventing the water from developing an odor and improving the user experience of the drinking device 1.

[0079] Understandably, in an embodiment where the water outlet includes a first water outlet 337 and a second water outlet 338, the drain hole 55 includes a first drain hole 55 and a second drain hole 55, with the first water outlet 337 connected to the first drain hole 55 and the second water outlet 338 connected to the second drain hole 55.

[0080] In this embodiment, the cold tank 31 has a cold tank 31 vent, and the pipeline structure 32 is correspondingly provided with an exhaust pipe and forms the aforementioned vent 339. The exhaust pipe connects the cold tank 31 vent and the vent 339, so that the internal space of the cold tank 31 is connected to the atmosphere through the exhaust hole 54 of the water outlet structure 50, thereby balancing the air pressure inside the cold tank 31 and allowing the water inside the cold tank 31 to be discharged smoothly. Since the exhaust hole 54 of this application is located on the water outlet structure 50, it can prevent the water inside the cold tank 31 from producing an odor, ensuring a good user experience when using cold water.

[0081] Of course, in other embodiments of this application, if the drinking water device 1 is provided with other water storage devices, it can also be connected to the atmosphere through the exhaust port 54 of the air outlet structure, which will not be elaborated here.

[0082] Taking the connection between the cooling tank 31 and the exhaust pipe as an example, in some embodiments, the exhaust pipe is installed on the water circuit board 33, and the water circuit board 33 forms the aforementioned air outlet 339. Integrating the exhaust pipe onto the water circuit board 33 reduces the number of pipes and joints, lowers the complexity of installation, improves assembly efficiency, and reduces the risk of air leakage due to improper pipe insertion or loose joints. In addition, the simple structure of the water circuit board 33 not only makes the internal structure of the drinking water device 1 neater and more aesthetically pleasing, but also facilitates maintenance and improves the reliability of the drinking water device 1.

[0083] Combination Figure 9 In some embodiments, the water circuit board 33 includes a board body 331, an air outlet 335, a water inlet 332, a first water outlet 333, and a second water outlet 334. The board body 331 defines at least a portion of a room temperature water pipe 34, a cold water pipe 35, an instant hot water pipe 36, and an exhaust pipe; the air outlet 335, water inlet 332, first water outlet 333, and second water outlet 334 are all connected to the board body 331 and respectively define an air outlet 339, a water inlet 336, a first water outlet 337, and a second water outlet 338. The air outlet 335, water inlet 332, first water outlet 333, and second water outlet 334 are all located on one side of the board body 331 and protrude from the side of the board body 331. Figure 6 and Figure 7 As shown, multiple on / off control components are installed on the outer side of the main body 331. The protruding air outlet 335, water inlet 332, first water outlet 333 and second water outlet 334 can make the positions of the air outlet 339, water inlet 336, first water outlet 337 and second water outlet 338 closer to the outer shell 10, which facilitates pipe connection operation and improves operation efficiency.

[0084] For ease of connection, the side wall of the outer casing 10 is also provided with a water outlet and an air outlet 154. The water outlet is exposed at the water outlet, and the air outlet 339 is exposed at the air outlet 154. Of course, in the structure where the water outlet includes a first water outlet 337 and a second water outlet 338, the outer casing 10 is provided with a first water outlet 152 and a second water outlet 153. The first water outlet 337 is exposed from the first water outlet 152, and the second water outlet 338 is exposed from the second water outlet 153.

[0085] The air outlet connector 335, water inlet connector 332, first water outlet connector 333, and second water outlet connector 334 are all connected to the water outlet structure 50 via pipelines. The shape and material of the water outlet structure 50 are not limited in this application embodiment. In some embodiments, the vent 54 on the water outlet structure 50 is oriented downwards. On the one hand, the vent 54 facing downwards is more concealed, improving the overall integrity and aesthetics of the water outlet structure 50. On the other hand, if a high-pressure or high-temperature airflow is discharged from the vent 54, it flows downwards, preventing the airflow from flowing towards the user and ensuring safety.

[0086] For example, the water outlet structure 50 includes a connecting section 51 and a cantilever section 52. The connecting section 51 is located above the main unit 1a. Specifically, the connecting section 51 can be directly connected to the main unit 1a, or it can be connected to a mounting base such as a kitchen stove or washbasin above the main unit 1a. Optionally, the connecting section 51 is generally tubular, with a thread at one end for threaded connection to the main unit 1a or the aforementioned mounting base, improving connection stability. The cantilever section 52 is connected to the connecting section 51 and extends at an angle to the vertical direction. For example, the connecting section 51 extends vertically, while the cantilever section 52 extends horizontally to facilitate water access for the user. Vent holes 54 and drain holes 55 are spaced apart on the cantilever section 52 to avoid mutual interference during venting and draining, which would affect the user experience. For example, the drain hole 55 is located at the end of the cantilever section 52 away from the connecting section 51, while the vent hole 54 is located in the middle of the cantilever section 52.

[0087] Furthermore, when the cantilever section 52 is horizontally extended, the vent 54 and the drain 55 are both located at the bottom of the cantilever section 52, which facilitates the natural flow of water and can conceal the vent 54 and the drain 55, thereby improving the aesthetic appearance of the water outlet structure 50.

[0088] Optionally, such as Figure 11 As shown, in some embodiments, the exhaust port 54 is flat and extends along the extension direction of the cantilever section 52. While ensuring the size of the exhaust port 54, it improves the aesthetics. The flat exhaust port 54 can also accelerate the gas flow and ensure smooth exhaust.

[0089] Combination Figure 10The connecting section 51 and the cantilever section 52 together define the pipe passage 53. The vent hole 54 and the drain hole 55 are both connected to the pipe passage 53. The water supply pipe and the air supply pipe are both located in the pipe passage 53. On the one hand, the water outlet structure 50 can protect the water supply pipe and the air supply pipe, avoid damage to the pipeline, and improve the reliability of the structure. On the other hand, converging the water supply pipe and the air supply pipe in the pipe passage 53 can also make the appearance of the water outlet structure 50 simpler and more integrated.

[0090] In this embodiment, the connecting section 51 and the cantilever section 52 can be an integral structure to further enhance the overall structure, or they can be two separately formed parts connected together to facilitate production. This embodiment does not limit the specific components.
