Detailed Implementation

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] Combination Figure 1 and Figure 2 The refrigeration assembly 100 according to an embodiment of the present invention can be used in drinking water equipment. The refrigeration assembly 100 includes: a cold storage tank 10, a heat exchanger 20, and a stirrer 30. The cold storage tank 10 has a chamber 11, and the heat exchanger 20 is configured to cool the medium in the chamber 11. Specifically, when the heat exchanger 20 operates, it can absorb heat from the medium in the chamber 11 to cool the medium. The stirrer 30 is configured to agitate the medium in the chamber 11. By setting the stirrer 30 to agitate the medium in the chamber 11, the temperature of the medium in the chamber 11 can be made more uniform, avoiding a large temperature difference between the medium near the heat exchanger 20 and the medium far from the heat exchanger 20. In addition, it can be understood that the medium with a lower temperature tends to flow downward, resulting in the medium at the bottom of the chamber 11 having a lower temperature and the medium at the top of the chamber 11 having a higher temperature. For example, when the medium is water, the water at the bottom of the chamber 11 is more likely to freeze than the water at the top. By setting the stirrer 30 to agitate the water in the chamber 11, the flow of water in the chamber 11 is accelerated, avoiding the problem of local freezing.

[0034] The refrigeration assembly 100 also includes a water delivery component 40, which has a flow channel for liquid circulation. At least a portion of the water delivery component 40 is disposed in the chamber 11 and exchanges heat with the medium within the chamber 11. Specifically, as liquid flows through the water delivery component 40, the medium within the chamber 11 absorbs the heat from the liquid in the water delivery component 40, thereby cooling the liquid. For example, the water delivery component 40 can be used to deliver liquids such as purified water, domestic water, and beverages.

[0035] Specifically, the chamber 11 may contain a medium, which absorbs heat from the medium through the heat exchanger 20 to achieve cooling. During the cooling process, the heat exchanger 20 agitates the medium with a stirrer 30 to make the temperature of the medium more uniform. When the liquid flows through the flow channel of the water conveying component 40, the medium absorbs heat from the liquid to achieve cooling. In other words, the liquid in the water conveying component 40 achieves cooling through indirect heat exchange with the heat exchanger 20, which avoids direct contact between the liquid and the heat exchanger 20, thus preventing contamination and maintaining the purity of the liquid. In addition, by agitating the medium in the chamber 11 with the stirrer 30, the temperature of the medium can be made more uniform, preventing localized low temperatures that could lead to localized freezing and blockage of the flow channel of the water conveying component 40.

[0036] According to the refrigeration component 100 of this utility model embodiment, the liquid in the water conveying component 40 is indirectly cooled by the heat exchanger 20, and the stirrer 30 is provided to agitate the medium in the chamber 11, which can improve the temperature uniformity of the medium in the chamber 11, avoid the local temperature of the medium being too low, which would cause the liquid in the water conveying component 40 to freeze and block the pipeline, and improve the working stability of the drinking water equipment.

[0037] The heat exchanger 20 is configured to cool the medium in the chamber 11. For example, the heat exchanger 20 can be located inside the chamber 11 to improve the heat exchange efficiency of the heat exchanger 20 to the medium; or, the heat exchanger 20 can be located outside the chamber 11, for example, the heat exchanger 20 can be embedded in the cold storage box 10.

[0038] For example, the water conveying component 40 can be a plate structure with flow channels arranged inside the plate; or, the water conveying component 40 can be a tubular structure with flow channels arranged inside the pipe. For example, the water conveying component 40 can be a stainless steel water pipe. By setting the water conveying component 40 to transport liquid, the liquid is prevented from contacting the component and causing liquid contamination.

[0039] The cold storage tank 10 can be pre-stored with a medium. For example, pure water can be pre-added to the cold storage tank 10, and the heat exchanger 20 cools the pure water, causing the pure water to form an ice storage layer in the cold storage tank 10, and also cooling the liquid in the water supply component 40; combined with Figure 3 Alternatively, the cold storage tank 10 may have a liquid inlet 15, which is connected to the chamber 11. The liquid inlet 15 can introduce a medium into the chamber 11, making it convenient to introduce or replenish the medium into the chamber 11.

[0040] Combination Figure 3 Optionally, the cold storage box 10 may be provided with a liquid outlet 16, which can be connected to the chamber 11 and can be used to discharge the medium in the chamber 11.

[0041] Optionally, the cold storage tank 10 may be provided with an inlet 15 and an outlet 16, which are connected to the chamber 11, allowing for convenient introduction and discharge of the medium into and out of the chamber 11. For example, when cooling of the liquid in the water supply unit 40 is required, the medium can be introduced into the chamber 11 through the inlet 15, or replenished through the inlet 15 if the medium in the chamber 11 is insufficient. After the cooling operation is completed, or when the water supply equipment is not used for a long time, the medium in the chamber 11 can be discharged through the outlet 16 to prevent the medium from prolonged contact with the heat exchanger 20 and affecting its service life. The medium can be water or refrigerant, etc. This application mainly uses water as an example and should not be construed as a limitation of the present invention.

[0042] For example, the drinking water equipment may be equipped with a refrigeration system 1000, which includes a compressor 200, a condenser 300, a throttling element 400, and the aforementioned refrigeration components 100. The compressor 200, condenser 300, throttling element 400, and heat exchanger 20 are connected in a loop. Taking water as the refrigerant, when the refrigeration system 1000 is working, the heat exchanger 20 absorbs heat from the water, which can gradually cool the water in the chamber 11. At this time, the stirrer 30 can work simultaneously to prevent cold water from flowing downwards and forming ice blocks at the bottom of the chamber 11. The stirrer 30 can accelerate the flow of water in the chamber 11, so that the water can form an ice storage layer evenly in the chamber 11, preventing the phenomenon of large local ice formation. This avoids the water in the chamber 11 freezing and blocking the pipeline during the heat exchange process with the liquid in the water delivery component 40, thereby improving the water output stability of the drinking water equipment. In addition, by setting water as the medium and stirring the water with a stirrer 30, a uniform ice layer can be formed in the chamber 11. The uniform ice accumulation can make the water outlet temperature of the drinking water equipment lower.

[0043] Combination Figure 2 In some embodiments of this utility model, the heat exchanger 20 is disposed in the chamber 11, which can improve the cooling efficiency of the heat exchanger 20 for the medium in the chamber 11, thereby improving the cooling efficiency of the liquid in the water conveying component 40.

[0044] Combination Figure 2 and Figure 4 Furthermore, the heat exchanger 20 is arranged around the water supply component 40, that is, the water supply component 40 is located on the inner side and the heat exchanger 20 is located on the outer side. The heat exchanger 20 cools the medium and then cools the liquid in the water supply component 40. The fact that the water supply component 40 is located on the inner side can improve the cooling efficiency of the liquid in the water supply component 40.

[0045] In some embodiments of this invention, the water conveying component 40 is arranged around the agitator 30, which facilitates the stirring of the medium inside the water conveying component 40 by the agitator 30, improving the temperature uniformity of the medium inside the water conveying component 40 and preventing the liquid inside the water conveying component 40 from freezing and clogging the pipeline due to excessively low local temperature of the medium. Additionally, the heat exchanger 20 is arranged around the agitator 30, which facilitates the stirring of the medium inside the heat exchanger 20 by the agitator 30, improving the temperature uniformity of the medium inside the heat exchanger 20 and preventing the liquid inside the water conveying component 40 from freezing and clogging the pipeline due to excessively low local temperature of the medium.

[0046] In some embodiments of this utility model, the heat exchanger 20 is disposed in the chamber 11, the heat exchanger 20 is arranged around the water supply component 40, and the water supply component 40 is arranged around the agitator 30. The agitator 30, the water supply component 40 and the heat exchanger 20 are arranged sequentially from the inside to the outside, so that the overall structure of the refrigeration component 100 is compact, improving the refrigeration efficiency of the liquid and avoiding the problem of local low temperature of the medium.

[0047] For example, the stirrer 30 can be located at the center of the chamber 11 to improve the stirring efficiency of the medium in the chamber 11 and avoid the problem of localized low temperature of the medium.

[0048] In some embodiments of this utility model, the stirrer 30 is arranged in a vertical direction, and the water conveying component 40 extends spirally from top to bottom, which facilitates increasing the contact area between the water conveying component 40 and the medium in the chamber 11, thereby improving the cooling efficiency of the water in the water conveying component 40. It is understood that after the medium in the chamber 11 is cooled by the heat exchanger 20, the colder medium tends to flow to the bottom of the chamber 11. The stirrer 30 is arranged in a vertical direction to facilitate uniform temperature distribution of the medium in both directions through agitation, preventing localized overcooling of the medium at the bottom and avoiding freezing and blockage of the pipeline by the liquid in the water conveying component 40.

[0049] In addition, the heat exchanger 20 includes multiple heat exchange sections distributed in the vertical direction. The heat exchange sections extend in the direction surrounding the stirrer 30, and the multiple heat exchange sections are connected to each other, which facilitates increasing the contact area between the heat exchanger 20 and the medium, improving the cooling efficiency and uniformity of the medium by the heat exchanger 20. Furthermore, the heat exchange sections extend in the direction surrounding the stirrer 30, and the heat exchanger 20 and the stirrer 30 work together to further improve the temperature uniformity of the medium in the chamber 11.

[0050] Combination Figure 3 The water supply component 40 has an inlet 41 and an outlet 42, which are connected to a flow channel. Specifically, liquid can enter the flow channel through the inlet 41 and flow out of the flow channel through the outlet 42. Optionally, the inlet 41, the outlet 42 and the liquid inlet 15 can be located on the same side of the cold storage box 10 to facilitate the pipeline connection of the refrigeration component 100.

[0051] For example, the medium can be water, and the water delivery component 40 can be used to deliver water. That is, the medium in the chamber 11 and the liquid delivered in the water delivery component 40 can be the same fluid. The drinking water device can include a water inlet assembly, through which the medium can be introduced into the chamber 11 and the fluid can be supplied to the water delivery component 40, simplifying the piping and structure of the drinking water device.

[0052] For example, the drinking water equipment may include a filter element. After filtration, water may be introduced into the chamber 11 through a first branch as a heat exchange medium, and a second branch is provided to supply water to the water delivery component 40 so that it can be cooled by the cooling component 100 and then cold water is discharged from the water outlet. By locating the water inlet 41, liquid inlet 15 and water outlet 42 on the same side of the cold storage tank 10, the pipeline connection of the cooling component 100 can be facilitated, making the structure of the drinking water equipment more compact.

[0053] At least a portion of the water supply component 40 is located in the chamber 11, and the inlet 41 and outlet 42 can extend out of the chamber 11 to facilitate the pipeline connection of the cooling component 100.

[0054] Combination Figure 3 Optionally, the cold storage tank 10 includes a barrel 12 and a cover 13. The cover 13 is placed on the upper end of the barrel 12, the liquid inlet 15 is located on the cover 13, and the liquid outlet 16 is located on the barrel 12. That is, the liquid inlet 15 is located at the upper end of the cold storage tank 10, and the liquid outlet 16 is located at the lower end of the cold storage tank 10, so as to facilitate the introduction of the medium into the chamber 11 through the liquid inlet 15 and the discharge of the medium in the chamber 11 through the liquid outlet 16.

[0055] Combination Figure 6 In some embodiments of this utility model, the refrigeration assembly 100 further includes a liquid level monitoring element 50, which is configured to monitor the liquid level in the chamber 11. For example, the cold storage tank 10 may pre-store a medium, which facilitates prompting the user or maintenance personnel to replenish the medium in the cold storage tank 10 when the liquid level in the chamber 11 is low. As another example, the cold storage tank 10 may have a liquid inlet 15. When a medium is introduced into the chamber 11 through the liquid inlet 15, the liquid level monitoring element 50 can monitor the liquid level in the chamber 11. When the liquid level reaches the upper limit, the valve can be controlled to stop the introduction of medium into the chamber 11; when the liquid level is below the lower limit, the valve can be controlled to introduce medium into the chamber 11, thereby improving the operational stability of the refrigeration assembly 100.

[0056] For example, the level monitoring device 50 may be a float, an ultrasonic level gauge, etc.

[0057] Optionally, the level monitoring device 50 includes a float disposed in the chamber 11 and used to monitor the water level in the chamber 11. The float can float up and down as the water level in the chamber 11 rises and falls. For example, the position of the float can trigger a valve to open and close the inlet 15. The float can accurately track changes in the water level in the chamber 11 and can avoid affecting the performance of the float when the temperature in the chamber 11 decreases, making it easy for the float to stably monitor the liquid level in the chamber 11.

[0058] Combination Figure 7 Optionally, in the projection along the vertical direction, the distance between the liquid level monitoring element 50 and the agitator 30 is L0, the minimum distance between the liquid level monitoring element 50 and the water supply element 40 is L1, the minimum distance between the liquid level monitoring element 50 and the heat exchanger 20 is L2, and the distance between the liquid level monitoring element 50 and the inner circumferential surface of the chamber 11 is L3, where L0 ≥ L1; or, L0 ≥ L2; or, L0 ≥ L3. Specifically, the water supply element 40 can be configured with different structures and shapes, therefore, the distance between different positions of the water supply element 40 and the liquid level monitoring element 50 is different, and L1 is the minimum distance between the liquid level monitoring element 50 and the water supply element 40; the heat exchanger 20 can also be configured with different structures and shapes, and the distance between different positions of the heat exchanger 20 and the liquid level monitoring element 50 may be different, and L2 is the minimum distance between the liquid level monitoring element 50 and the heat exchanger 20.

[0059] Understandably, during operation, the stirrer 30 agitates the medium in the chamber 11, causing changes in the liquid level. The distance between the liquid level monitoring element 50 and the stirrer 30 is relatively large to prevent the stirrer 30 from affecting the monitoring results of the liquid level monitoring element 50 during operation. In addition, the relative positions of the water supply element 40, the heat exchanger 20, and the chamber 11 are fixed. Therefore, by optimizing the position of the components, placing the liquid level monitoring element 50 closer to the water supply element 40, the heat exchanger 20, and the chamber 11, and with a larger distance between it and the stirrer 30, the accuracy of the monitoring results of the liquid level monitoring element 50 can be improved, and the operational stability of the refrigeration assembly 100 can be enhanced.

[0060] Combination Figure 2 and Figure 5 In some embodiments of this utility model, the stirrer 30 includes a drive member 31 and a stirring member 32. At least a portion of the stirring member 32 is disposed within the chamber 11. The drive member 31 is convexly connected to the stirring member 32 and is used to drive the stirring member 32 to agitate the medium within the chamber 11. Specifically, the drive member 31 operates, driving the stirring member 32 to rotate, enabling the stirring member 32 to agitate the medium within the chamber 11 and preventing uneven temperature distribution and localized freezing of the medium within the chamber 11. For example, the rotational speed of the stirring member 32 can be adjusted by adjusting the rotational speed of the drive member 31, or the rotational frequency of the stirring member 32 can be adjusted by adjusting the operating frequency of the drive member 31. For instance, a temperature detection element can be provided within the chamber 11 to detect the temperature of the medium within the chamber 11. When the temperature of the medium is higher than the target temperature, the drive member 31 can operate at a higher speed; when the temperature approaches the target temperature, the rotational speed of the drive member 31 can be reduced.

[0061] Combination Figure 2 and Figure 5 Furthermore, the cold storage box 10 includes a barrel body 12 and a cover body 13. The cover body 13 is placed on the upper end of the barrel body 12, and the drive component 31 is connected to the cover body 13. By connecting the drive component 31 to the cover body 13, it is convenient to install the stirrer 30, facilitate the later maintenance of the stirrer 30, and avoid setting up a structure for installing the drive component 31 inside the barrel body 12, which would affect the sealing performance of the barrel body 12.

[0062] Combination Figure 5In some embodiments of this utility model, the cover 13 includes an inner cover 131 and an outer cover 132. The inner cover 131 and the outer cover 132 are stacked and connected to improve the connection stability of the inner cover 131 and the outer cover 132. The inner cover 131 covers the upper end of the barrel 12 and is provided with a positioning groove for the positioning drive component 31, which improves the installation efficiency and structural stability of the drive component 31. In addition, the drive component 31 is located between the inner cover 131 and the outer cover 132. The inner cover 131 and the outer cover 132 cooperate to protect the drive component 31, improve the structural stability of the drive component 31, and prevent fluid from entering the drive component 31. This allows the drive component 31 to stably drive the stirring component 32 to stir the medium in the chamber 11.

[0063] Combination Figure 5 In some embodiments of this utility model, the cold storage box 10 includes a barrel body 12 and a cover body 13, with the cover body 13 covering the barrel body 12. The barrel body 12 includes an inner barrel 121 and an outer barrel 122, with the inner barrel 121 located inside the outer barrel 122. A first insulation layer 123 is provided between the inner barrel 121 and the outer barrel 122. The first insulation layer 123 can prevent the loss of cold energy in the cold storage box 10 and prevent external heat from entering the cold storage box 10, thus maintaining a lower temperature environment inside the chamber 11 and improving cooling efficiency.

[0064] In addition, the cover 13 includes an inner cover 131 and an outer cover 132. The inner cover 131 and the outer cover 132 are stacked and connected. The inner cover 131 covers the barrel 12. A second insulation layer 133 is provided between the inner cover 131 and the outer cover 132. The second insulation layer 133 can prevent the loss of cold energy in the cold storage box 10 and prevent external heat from entering the cold storage box 10, so as to maintain a low temperature environment in the chamber 11 and improve the refrigeration efficiency.

[0065] In some embodiments of this utility model, the heat exchanger 20 is disposed in the chamber 11 and spaced apart from the inner surface of the chamber 11. The medium can flow in the gap between the heat exchanger 20 and the chamber 11, which can improve the cooling efficiency of the heat exchanger 20 on the medium and avoid the loss of cooling capacity due to direct contact between the heat exchanger 20 and the inner surface of the chamber 11.

[0066] Furthermore, the inner circumferential surface of the chamber 11 is provided with a plurality of ribs 14, which are distributed along the circumference of the chamber 11. The ribs 14 separate the heat exchanger 20 from the inner surface of the chamber 11. The provision of a plurality of ribs 14 on the inner circumferential surface of the chamber 11 can, on the one hand, improve the structural strength of the chamber 11, enabling the chamber 11 to adapt to temperature changes, and on the other hand, facilitate the separation of the heat exchanger 20 from the inner surface of the chamber 11, which facilitates the flow of the medium in the gap between the inner surface of the chamber 11 and the heat exchanger 20, thereby improving the cooling efficiency of the heat exchanger 20 for the medium.

[0067] Combination Figure 8The present invention also provides a refrigeration system 1000 for a drinking water device. The refrigeration system 1000 includes a compressor 200, a condenser 300, a throttling element 400 and the aforementioned refrigeration component 100, wherein the compressor 200, the condenser 300, the throttling element 400 and the heat exchanger 20 are connected in a loop.

[0068] Furthermore, the cold storage box 10, compressor 200, and condenser 300 are arranged sequentially in the vertical direction to optimize the layout of the refrigeration system 1000, making the overall structure of the refrigeration system 1000 more compact and improving space utilization.

[0069] The drinking water device according to the present utility model includes the aforementioned refrigeration component 100, or includes the aforementioned refrigeration system 1000.

[0070] For example, the water supply component 40 may have an inlet 41 and an outlet 42.

[0071] The drinking water equipment also includes a water outlet component, which is used to supply cold water. The water outlet 42 is connected to the water outlet component, and cold water can be supplied to the user through the water outlet component. By setting the aforementioned cooling component 100, the water outlet stability of the water outlet component can be improved.

[0072] The drinking water equipment may also include a drainage component for discharging wastewater. The outlet 16 is connected to the drainage component, which can discharge the medium in the chamber 11 to prevent the medium from being stored in the chamber 11 for a long time and affecting the service life of the heat exchanger 20.

[0073] Additionally, the drinking water equipment may include a water inlet assembly. For example, the water inlet assembly can supply water to the chamber 11 and flow water into the water delivery component 40. Specifically, the water inlet assembly may include a multi-port valve. The multi-port valve has an inlet port, a first port, and a second port. The inlet port can be connected to an inlet pipe, the first port is connected to the liquid inlet 15, and the second port is connected to the water inlet 41 of the water delivery component 40. The multi-port valve can control the inlet port to selectively connect to the first port and the second port. For example, when water cooling is required, the multi-port valve can first connect the inlet port and the first port to flow water into the chamber 11. After the target amount of water has been flowed in, the inlet port and the first port can be disconnected, and the water is cooled by the heat exchanger 20. Simultaneously, the stirrer 30 operates to form a uniform ice layer in the chamber 11. The multi-port valve connects the inlet port and the second port to flow water into the water delivery component 40. The ice layer can cool the water in the water delivery component 40, increasing the outlet temperature of the first cup of cold water.
