Detailed Implementation

[0038] 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.

[0039] Combination Figure 1 and Figure 2 According to an embodiment of the present utility model, the cooling component 100 of the drinking water equipment includes: a cold storage box 10 and a heat exchanger 20. The cold storage box 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 is working, it can absorb the heat of the medium in the chamber 11 to cool the medium.

[0040] The refrigeration assembly 100 also includes a stirrer 30, which is configured to agitate the medium in the chamber 11. By agitating the medium in the chamber 11 with the stirrer 30, 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 a lower temperature of the medium at the bottom of the chamber 11 and a higher temperature at the top of the chamber 11. 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 agitating the water in the chamber 11 with the stirrer 30, the flow of water in the chamber 11 is accelerated, avoiding the problem of local freezing.

[0041] Combination Figure 2 and Figure 4The agitator 30 includes a drive component 31 and an agitator 32. The agitator 32 is disposed within the chamber 11 and includes a drive shaft 321 and blades 322. The drive shaft 321 is connected to the drive component 31, and the blades 322 are connected to the drive shaft 321 and extend along the length of the drive shaft 321. Specifically, when the drive component 31 operates, it drives the blades 322 to rotate via the drive shaft 321, enabling the blades 322 to agitate the medium within the chamber 11. This prevents uneven temperature distribution of the medium within the chamber 11, which would affect the cooling efficiency of the liquid in the water supply component 40. The blades 322 extending along the length of the drive shaft 321 enhance the structural strength of the blades 322 and their stability during rotation, thereby improving the agitation efficiency of the medium.

[0042] It should be noted that the blade 322 extends along the length of the drive shaft 321. The extension direction of the blade 322 may be completely consistent with the extension direction of the drive shaft 321, or the blade 322 may have a certain tilt angle relative to the length of the drive shaft 321.

[0043] For example, the rotational speed of the agitator 32 can be adjusted by adjusting the rotational speed of the drive unit 31, or the rotational frequency of the agitator 32 can be adjusted by adjusting the operating frequency of the drive unit 31. For instance, a temperature detection element can be provided in the chamber 11 to detect the temperature of the medium in the chamber 11. When the temperature of the medium is higher than the target temperature, the drive unit 31 can operate at a higher rotational speed. When the temperature is close to the target temperature, the rotational speed of the drive unit 31 can be reduced.

[0044] Combination Figure 2 The refrigeration assembly 100 also includes a water conveying component 40, which has a flow channel for liquid circulation. At least a portion of the water conveying component 40 is located in the chamber 11 and exchanges heat with the medium within the chamber 11. Specifically, as liquid flows through the water conveying component 40, the medium within the chamber 11 absorbs the heat from the liquid in the water conveying component 40, thereby cooling the liquid. For example, the water conveying component 40 can be used to convey liquids such as purified water, domestic water, and beverages. By providing the water conveying component 40, liquid contamination can be avoided, and the purity of the liquid can be improved.

[0045] Specifically, the heat exchanger 20 absorbs heat from the medium in the chamber 11 to cool the medium. During the cooling process, the heat exchanger 20 agitates the medium using the stirrer 30, making the temperature of the medium in the chamber 11 more uniform. When the liquid flows through the flow channel of the water conveying component 40, the medium absorbs heat from the liquid, thus cooling the liquid. In other words, the liquid in the water conveying component 40 and the heat exchanger 20 achieve cooling through indirect cooling, which can prevent the liquid from being contaminated and maintain the purity of the liquid. In addition, by setting the stirrer 30, which has blades 322 extending along the length of the drive shaft 321, the stirring efficiency of the medium in the chamber 11 can be improved, making the temperature of the medium more uniform and preventing local low temperatures in the medium, which could lead to local freezing and blockage of the flow channel of the water conveying component 40, thus making the outlet water temperature of the water conveying component 40 more stable.

[0046] According to the refrigeration component 100 of this utility model embodiment, the liquid in the water supply component 40 is indirectly cooled by the heat exchanger 20, and a 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 supply component 40 to freeze and block the pipeline, and make the outlet water temperature of the water supply component 40 stable.

[0047] 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.

[0048] 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, which improves the heat exchange efficiency of the heat exchanger 20 on 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. The cold storage box 10 can be pre-stored with a medium. For example, pure water can be pre-added to the cold storage box 10, and the heat exchanger 20 cools the pure water, causing the pure water to form an ice layer inside the cold storage box 10, and also cooling the liquid in the water supply component 40; or, combined with... Figure 3 The cold storage tank 10 may have a liquid inlet 12, which connects to the chamber 11. The liquid inlet 12 allows the medium to be introduced into the chamber 11, facilitating the introduction or replenishment of the medium. For example, when liquid cooling is required, the medium can be introduced into the chamber 11 through the liquid inlet 12, or if the medium in the chamber 11 is insufficient, the medium can be replenished into the chamber 11 through the liquid inlet 12.

[0049] Combination Figure 3Optionally, the cold storage box 10 has a liquid outlet 13 that connects to the chamber 11. After the refrigeration work is finished, or when the drinking water equipment is not used for a long time, the medium in the chamber 11 can be discharged through the liquid outlet 13 to avoid the medium being stored in the chamber 11 for a long time and affecting the service life of the internal components of the chamber 11.

[0050] The medium can be water or refrigerant, etc. This application mainly uses water as an example for illustration.

[0051] 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 stirring blades 322 can accelerate the flow of water in the chamber 11, preventing the phenomenon of local large ice formation. This prevents the water in the chamber 11 from freezing and blocking the pipes during the heat exchange process with the liquid in the water delivery component 40, making the water output from the water delivery component 40 more stable. In addition, by setting water as the medium and stirring the water with the agitator 32, a uniform ice storage layer can be formed in the chamber 11, which can make the water outlet temperature of the drinking water equipment lower.

[0052] In addition, when the temperature of the medium in chamber 11 differs significantly from the target temperature, the compressor 200 can be controlled to operate at a higher frequency to improve the cooling efficiency of the heat exchanger 20. At the same time, the stirrer 30 can be controlled to rotate at a higher speed to prevent the local temperature of the medium from becoming too low during rapid cooling. When the temperature of the medium in chamber 11 differs slightly from the target temperature, the compressor 200 can be controlled to operate at a lower frequency. At the same time, the stirrer 30 can be controlled to rotate at a lower speed. Of course, the operating frequency of the stirrer 30 can also be adjusted according to the temperature of the medium in chamber 11. For example, when the water temperature T in chamber 11 meets the condition of 1℃≤T<5℃, the stirrer 30 can operate at a frequency of 4 minutes on and 1 minute off. When the water temperature T in chamber 11 meets the condition of -2.5℃≤T<1℃, the stirrer 30 can operate at a frequency of 2 minutes on and 1 minute off to prevent the local temperature in chamber 11 from becoming too low and causing large ice formation.

[0053] Combination Figure 4 In some embodiments of this utility model, the blade 322 is inclined around the circumference of the transmission shaft 321 along the axis of the transmission shaft 321, which reduces the impact between the medium and the blade 322 during the rotation process, reduces the resistance of the blade 322 during the stirring process, and at the same time, the reduced stirring resistance can also reduce the noise during the stirring process.

[0054] The blades 322 may include multiple blades arranged circumferentially along the drive shaft 321. By providing multiple blades 322, the medium is simultaneously agitated during the rotation of the agitator 32, which can improve the agitation effect of the medium and further enhance the temperature uniformity of the medium in the chamber 11. For example, the number of blades 322 may be two, three, four, five, etc.

[0055] In some embodiments of this invention, the helix angle of the blade 322 is greater than 0° and less than or equal to 30°. The helix angle of the blade 322 refers to the angle between the tangent direction of the blade 322 and the axis of the drive shaft 321 during rotation. A helix angle greater than 0° can appropriately reduce the impact between the blade 322 and the medium, thereby reducing resistance during the stirring process. Simultaneously, a helix angle less than or equal to 30° prevents excessive twisting of the blade 322, which would increase the stress on the blade 322 and potentially lead to insufficient radial flow of the medium, resulting in uneven stirring and affecting the temperature uniformity of the medium in the chamber 11. By controlling the helix angle between 0° and 30°, the resistance of the blade 322 during stirring can be reduced, the noise during stirring can be reduced, and the uniformity of stirring can be improved. For example, the helix angle can be 10°, 15°, 16°, 19°, 20°, 25°, etc.

[0056] Preferably, the helix angle is 15°, which can reduce the resistance of the blade 322 during the stirring process, improve the uniformity of stirring of the medium in the chamber 11, and reduce the noise during the stirring process.

[0057] Combination Figure 2 In some embodiments of this utility model, the stirring element 32 extends in the vertical direction. It can be understood that after the medium in the chamber 11 is cooled by the heat exchanger 20, the medium with a low temperature tends to flow to the bottom of the chamber 11. The stirring element 32 is arranged in the vertical direction to facilitate the mixing of the medium in the vertical direction by the stirring of the blades 322, thereby improving the uniformity of the medium temperature.

[0058] The upper end of the blade 322 is not higher than the highest set water level of the chamber 11, which can reduce the water level fluctuation of the medium during the rotation of the blade 322.

[0059] For example, the refrigeration assembly 100 may be equipped with a liquid level monitoring device 50 to monitor the liquid level in the chamber 11. The upper end of the blade 322 is not higher than the highest water level in the chamber 11, which can reduce the fluctuation of the medium water level and thus avoid excessive fluctuation of the medium water level from affecting the monitoring results of the liquid level monitoring device 50.

[0060] Combination Figure 2In some embodiments, the lower end of the blade 322 is flush with the lower end of the drive shaft 321, so that the medium with a lower temperature can easily flow downward to the chamber 11, so that the medium below the chamber 11 can be stirred by the stirring member 32, thereby improving the uniformity of stirring of the medium.

[0061] Combination Figure 4 In some embodiments of this utility model, the drive shaft 321 extends in the vertical direction, and the outer peripheral surface of the lower part of the drive shaft 321 is configured as a conical surface that gradually narrows from top to bottom, which can reduce the resistance of the stirring component 32 during the stirring process and improve the stirring efficiency of the medium.

[0062] Combination Figure 5 In some embodiments of the utility model, the distance between different positions of the outer edge 322a of the blade 322 and the axis of the drive shaft 321 is the same, which can improve the stability of the blade 322 during the stirring process.

[0063] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the drive shaft 321 extends vertically, and the outer peripheral surface of the lower part of the drive shaft 321 is configured as a tapered surface that gradually tapers inward from top to bottom. The distance between different positions of the outer edge 322a of the blades 322 and the axis of the drive shaft 321 is the same. Relatively speaking, the distance from the inner edge to the outer edge of the lower blade 322 is greater than the distance from the inner edge to the outer edge of the upper blade 322. This arrangement allows for a larger area of ​​the lower blades 322. Combined with the aforementioned, when the heat exchanger 20 cools the medium, the lower-temperature medium flows downward more easily. The larger lower blades 322 facilitate increasing the contact area between the lower blades 322 and the medium, thereby increasing the flow rate of the lower medium through stirring, making the medium temperature in the chamber 11 more uniform. When the medium is water, the water at the bottom of the chamber 11 freezes more easily than the water at the top. The aforementioned design of the blades 322 and drive shaft 321 prevents the problem of localized freezing of the water at the bottom.

[0064] In conjunction with the foregoing, during the cooling process of the heat exchanger 20, the lower-temperature medium tends to flow downwards. The blades 322 are inclined circumferentially around the axis of the drive shaft 321, and the blades 322 include multiple blades spaced apart circumferentially along the drive shaft 321. A stirring channel can be constructed between adjacent blades 322. Furthermore, the lower outer circumferential surface of the drive shaft 321 gradually narrows inwards from top to bottom. The distance between different positions of the outer edges 322a of the blades 322 and the axis of the drive shaft 321 is the same. The lower blades 322 have a larger area, and the lower end of the agitator 32 has a larger stirring channel. This allows the agitator 32 to have greater stirring efficiency for the fluid below the chamber 11 during stirring. Therefore, the flow rate of the fluid below the chamber 11 is greater, enabling the medium in the chamber 11 to be stirred more uniformly and preventing the problem of excessively low medium temperature and large ice formation below the chamber 11.

[0065] Combination Figure 6 In some embodiments of this utility model, the distance between the outer edge 322a of the blade 322 and the axis of the drive shaft 321 is L1, the distance between the inner edge 322b of the blade 322 and the axis of the drive shaft 321 is L2, and the maximum radius of the drive shaft 321 is L0, where 1.4 ≤ (L1-L2) / L0 ≤ 1.7. During rotation, the agitator 32 drives the blade 322 to agitate the fluid via the drive shaft 321. The rotating shaft can transmit torque. By designing the dimensions of the blade 322 and the drive shaft 321 within a reasonable range, the agitation efficiency of the blade 322 and the structural strength of the agitator 32 can be improved. Specifically, (L1-L2) / L0 is greater than or equal to 1.4, which facilitates the acceleration of medium flow through the blade 322 during rotation, improving the temperature uniformity of the medium in the chamber 11 and enhancing the performance of the agitator 32. Furthermore, (L1-L2) / L0 is less than or equal to 1.7 to prevent deformation of the blade 322 during agitation. For example, (L1-L2) / L0 can be set to 1.4, 1.51, 1.52, 1.55, 1.6, etc.

[0066] Combination Figure 6 and Figure 7In some embodiments of this utility model, the distance between the outer edge 322a of the blade 322 and the axis of the drive shaft 321 is L1, and the distance between the inner circumferential surface of the chamber 11 and the axis of the drive shaft 321 is L5, wherein 0.1≤L1 / L3≤0.25. By setting the size of the blade 322 and the size of the chamber 11 within a reasonable range, the stirring efficiency of the blade 322 on the medium in the chamber 11 can be improved, the uniformity of the medium stirring can be improved, and the blade 322 can avoid occupying too much space in the chamber 11. For example, L1 / L3 can be 0.15, 0.17, 0.2, 0.21, etc. Among them, L1 / L3 is greater than or equal to 0.1 to avoid the distance between the blade 322 and the chamber 11 being too small, causing the stirrer 30 to occupy too much space in the chamber 11 and the noise of the fluid during stirring. L1 / L3 is less than or equal to 0.25 to avoid the blade 322 being too small to stir the medium in the chamber 11 to flow uniformly, affecting the uniformity of stirring.

[0067] Combination Figure 7 and Figure 8 In some embodiments of the present invention, the refrigeration assembly 100 further includes a liquid level monitoring element 50, which is configured to monitor the liquid level in the chamber 11.

[0068] For example, the cold storage tank 10 may have a liquid inlet 12. When the medium is introduced into the chamber 11 through the liquid inlet 12, the liquid level of the medium in the chamber 11 can be monitored by the liquid level monitoring device 50. When the liquid level reaches the upper limit, the valve can be controlled to stop the medium from being introduced into the chamber 11. When the liquid level is lower than the lower limit, the valve can be controlled to introduce the medium into the chamber 11, thereby improving the working stability of the refrigeration component 100.

[0069] In the projection along the vertical direction, the minimum distance between the liquid level monitoring component 50 and the drive shaft 321 is L4, 0.2≤L1 / L4≤0.3. By setting the size of the blade 322 and the distance between it and the liquid level monitoring component 50 within a reasonable range, the influence of the blade 322 on the liquid level during the stirring process is reduced, thus affecting the monitoring results of the liquid level monitor.

[0070] For example, the level monitor can be a float, an ultrasonic level gauge, etc.

[0071] Combination Figure 6 and Figure 7Optionally, the distance between the outer edge 322a of the blade 322 and the axis of the drive shaft 321 is L1, and the minimum distance between the water conveying component 40 and the axis of the drive shaft 321 is L5, where 0.4 ≤ L1 / L5 ≤ 0.5. The water conveying component 40 can be configured with different structures and shapes; therefore, the distance between different positions of the water conveying component 40 and the axis of the drive shaft 321 is different, and L5 is the minimum distance between the water conveying component 40 and the axis of the drive shaft 321. A certain distance is set between the agitator 32 and the water conveying component 40 to avoid interference between the agitator 32 and the agitator 32 during the agitation process, which would affect the agitation effect and generate noise. By setting a reasonable distance between L1 and L5, the uniformity of agitation by the agitator 32 can be improved, and the noise during the agitation process can be reduced.

[0072] Combination Figure 6 and Figure 7 Optionally, the heat exchanger 20 is located in the chamber 11. The distance between the outer edge 322a of the blades 322 and the axis of the drive shaft 321 is L1, and the minimum distance between the heat exchanger 20 and the axis of the drive shaft 321 is L6, where 0.2 ≤ L1 / L6 ≤ 0.3. The heat exchanger 20 can be configured with different structures and shapes, and the distance between different positions of the heat exchanger 20 and the axis of the drive shaft 321 may vary. L6 is the minimum distance between the heat exchanger 20 and the axis of the drive shaft 321. A certain distance is set between the stirring element 32 and the heat exchanger 20 to avoid interference between the stirring element 32 and the stirring process, which would affect the stirring effect and generate noise. By setting a reasonable distance between L1 and L6, the uniformity of stirring by the stirring element 32 can be improved, and the noise during the stirring process can be reduced.

[0073] 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 12. 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, facilitating stable monitoring of the liquid level in the chamber 11.

[0074] Combination Figure 7 and Figure 8Optionally, in the projection along the vertical direction, the distance between the liquid level monitoring element 50 and the outer edge of the blade 322 is D0, the minimum distance between the liquid level monitoring element 50 and the water conveying element 40 is D1, the distance between the liquid level monitoring element 50 and the heat exchanger 20 is D2, and the distance between the liquid level monitoring element 50 and the inner circumferential surface of the chamber 11 is D3, where D0 ≥ D1; or, D0 ≥ D2; or, D0 ≥ D3. Specifically, the water conveying element 40 can be configured with different structures and shapes, therefore, the distance between different positions of the water conveying 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 conveying 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.

[0075] Understandably, during operation, the blades 322 of the agitator 32 will stir the medium in the chamber 11, causing changes in the liquid level in the chamber 11. The distance between the liquid level monitoring element 50 and the outer edge of the blades 322 is relatively large to avoid the blades 322 affecting the monitoring results of the liquid level monitor during rotation. 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 agitator 30, the accuracy of the monitoring results of the liquid level monitoring element 50 can be improved, and the working stability of the refrigeration assembly 100 can be enhanced.

[0076] Combination Figure 3 Optionally, the water supply component 40 has an inlet 41 and an outlet 42, which connect to a flow channel. The cold storage tank 10 may have a liquid inlet 12 connecting to the chamber 11. The inlet 41, outlet 42, and liquid inlet 12 are located on the same side of the cold storage tank 10. Specifically, liquid can enter the flow channel through the inlet 41 and flow out of the flow channel through the outlet 42. The inlet 41, outlet 42, and liquid inlet 12 being located on the same side of the cold storage tank 10 facilitates the pipeline connection of the refrigeration component 100 and optimizes the flow path of the drinking water equipment.

[0077] 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 assembly, simplifying the flow path and structure of the drinking water device.

[0078] For example, the drinking water device may include a filter element. After filtration, water can be introduced into the chamber 11 via a first branch as a heat exchange medium, and supplied to the water delivery component 40 via a second branch. After being cooled by the cooling component 100, cold water is dispensed from the outlet. By locating the inlet 41, liquid inlet 12, and outlet 42 on the same side of the cold storage tank 10, the piping connection of the cooling component 100 can be facilitated, making the structure of the drinking water device more compact. In addition, the inlet 41 and liquid inlet 12 can face the same side, while the outlet 42 can face the other side, facilitating the piping connection of the cooling component 100 and optimizing the flow path of the drinking water device.

[0079] 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 refrigeration component 100.

[0080] Optionally, the cold storage tank 10 has an inlet 12 and an outlet 13, which communicate with the chamber 11. The cold storage tank 10 includes a barrel 14 and a cover 15. The cover 15 is placed on the upper end of the barrel 14, the inlet 12 is located on the cover 15, and the outlet 13 is located on the bottom wall of the barrel 14. That is, the inlet 12 is located at the upper end of the cold storage tank 10, and the outlet 13 is located at the lower end of the cold storage tank 10, which facilitates the introduction of the medium into the chamber 11 through the inlet 12 and the discharge of the medium from the chamber 11 through the outlet 13.

[0081] Combination Figure 8 and Figure 9 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.

[0082] Combination Figure 8 and Figure 9 In some embodiments of this utility model, the heat exchanger 20 is arranged around the water conveying component 40. That is, the water conveying 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 conveying component 40. The inner side of the water conveying component 40 facilitates the cooling of the water conveying component 40 by the medium, thereby improving the cooling efficiency of the liquid in the water conveying component 40.

[0083] Combination Figure 8 and Figure 9In some embodiments of this utility model, the water conveying component 40 is arranged around the stirring component 32, making full use of the space inside the water conveying component 40. This facilitates the stirring of the medium inside the water conveying component 40 by the stirring component 32, improving the temperature uniformity of the medium inside the water conveying component 40. This prevents the liquid inside the water conveying component 40 from freezing and blocking the pipeline due to excessively low local temperatures, thereby improving the water output stability of the water conveying component 40 and enhancing the stability of the water output temperature. Furthermore, the heat exchanger 20 is arranged around the stirring component 32, facilitating the stirring of the medium inside the heat exchanger 20 by the stirring component 32. This improves the temperature uniformity of the medium inside the heat exchanger 20 and prevents the liquid inside the water conveying component 40 from freezing and blocking the pipeline due to excessively low local temperatures.

[0084] Combination Figure 8 and Figure 9 In some embodiments of this utility model, the heat exchanger 20 is arranged around the water supply component 40, and the water supply component 40 is arranged around the stirring component 32. The stirring component 32, 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.

[0085] For example, the agitator 32 can be positioned at the center of the chamber 11 to improve the uniformity of agitation of the medium in the chamber 11 and avoid the problem of localized low temperature of the medium.

[0086] Combination Figure 9 In some embodiments of this utility model, the stirring element 32 is arranged in the vertical direction, and the water conveying element 40 extends spirally from top to bottom, which facilitates increasing the contact area between the water conveying element 40 and the medium in the chamber 11, thereby improving the cooling efficiency of the water in the water conveying element 40. It is understood that after the medium in the chamber 11 is cooled by the heat exchanger 20, the lower-temperature medium tends to flow to the bottom of the chamber 11. The stirring element 32 is arranged in the vertical direction to facilitate increased flow of the medium in the vertical direction through agitation, thereby improving the uniformity of the medium temperature.

[0087] 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 stirring member 32, 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 heat exchanger 20 for the medium. Furthermore, the extension of the heat exchange sections around the stirring member 32 further improves the temperature uniformity of the medium in the chamber 11.

[0088] Combination Figure 10In some embodiments of this utility model, the cold storage tank 10 includes a barrel body 14 and a cover 15. The cover 15 is placed on the upper end of the barrel body 14, and the drive component 31 is connected to the cover 15. By connecting the drive component 31 to the cover 15, it is convenient to install the drive component 31, facilitates the later maintenance of the stirring component 32, and avoids setting a structure for installing the drive component 31 inside the barrel body 14, which would affect the sealing performance of the barrel body 14.

[0089] Combination Figure 10 In some embodiments of this utility model, the cover 15 includes an inner cover 151 and an outer cover 152. The inner cover 151 and the outer cover 152 are stacked and connected to improve the connection stability of the inner cover 151 and the outer cover 152. The inner cover 151 covers the upper end of the barrel 14 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 151 and the outer cover 152. The inner cover 151 and the outer cover 152 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.

[0090] Combination Figure 10 Optionally, the cold storage box 10 includes a barrel body 14 and a cover body 15, with the cover body 15 covering the barrel body 14. The barrel body 14 includes an inner barrel 141 and an outer barrel 142, with the inner barrel 141 located inside the outer barrel 142. A first insulation layer 143 is provided between the inner barrel 141 and the outer barrel 142. The first insulation layer 143 can prevent heat from the outside of the cold storage box 10 from entering the barrel body 14, thereby maintaining a lower temperature environment inside the chamber 11, avoiding the loss of cold energy, and improving the refrigeration efficiency.

[0091] In addition, the cover 15 includes an inner cover 151 and an outer cover 152, which are stacked together. The inner cover 151 covers the barrel 14, and a second insulation layer 153 is provided between the inner cover 151 and the outer cover 152. The second insulation layer 153 can prevent heat from the outside of the cold storage box 10 from entering the chamber 11, so as to maintain a lower temperature environment inside the chamber 11, avoid the loss of cold energy, and improve the refrigeration efficiency.

[0092] Optionally, the heat exchanger 20 is disposed inside 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.

[0093] Furthermore, the inner circumferential surface of the chamber 11 is provided with multiple ribs, which are distributed along the circumference of the chamber 11. The ribs separate the heat exchanger 20 from the inner surface of the chamber 11. The multiple ribs on the inner circumferential surface of the chamber 11 can improve the structural strength of the chamber 11, enabling it to adapt to temperature changes. On the other hand, they facilitate the separation of the heat exchanger 20 from the inner surface of the chamber 11, allowing the medium to flow 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.

[0094] Furthermore, the cold storage tank 10, with its body 14 and cover 15, allows the heat exchanger 20, agitator 30, and water supply component 40 to be connected to the cover 15, facilitating the installation of the refrigeration assembly 100. During installation, the agitator 30, heat exchanger 20, and water supply component 40 can be installed onto the cover 15 first, and then the cover 15 can be connected to the body 14, improving the installation efficiency of the refrigeration assembly 100. When assembling the agitator 30, the drive component 31 can be installed between the inner cover 151 and the outer cover 152 first, and then the agitator 32 can be connected to the drive component 31.

[0095] Combination Figure 11 and Figure 12 This utility model 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 components 100. The compressor 200, condenser 300, throttling element 400, and heat exchanger 20 are connected in a circuit. Exemplarily, the refrigerant absorbs heat in the heat exchanger 20, cooling the medium in the chamber 11, becoming a low-pressure, low-temperature gas, which enters the compressor 200. The compressor 200 compresses the refrigerant gas, increasing its pressure and temperature. The high-temperature, high-pressure refrigerant gas enters the condenser 300, exchanges heat with the surrounding environment, releases heat into the environment, and liquefies into a high-pressure liquid. The high-pressure liquid passes through the throttling element 400, causing a sudden drop in pressure and temperature, forming a low-pressure, low-temperature liquid refrigerant that enters the heat exchanger 20, absorbing heat from the medium and cooling the medium.

[0096] 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.

[0097] The drinking water device according to the present utility model includes the aforementioned refrigeration component 100, or includes the aforementioned refrigeration system 1000.

[0098] For example, the water supply component 40 may have an inlet 41 and an outlet 42.

[0099] 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.

[0100] Optionally, the drinking water equipment may also include a drainage component for discharging wastewater. The cold storage tank 10 may have a liquid outlet 13 that communicates with the chamber 11. The liquid outlet 13 may be connected to the drainage component, which can discharge the medium in the chamber 11 to avoid the medium from being stored in the chamber 11 for a long time and affecting the service life of the internal components of the chamber 11.

[0101] Additionally, the cold storage box 10 may have a liquid inlet 12 communicating with the chamber 11. The drinking water equipment may include a water inlet assembly, which may supply water medium into the chamber 11 and supply water into the water conveying component 40. Specifically, the water inlet assembly may include a multi-way valve, which has a water inlet interface, a first interface and a second interface. The water inlet interface may be connected to a water inlet pipeline, the first interface is connected to the liquid inlet 12, and the second interface is connected to the water inlet 41. The multi-way valve may control the water inlet interface to selectively connect to the first interface and the second interface. For example, when water cooling is required, the multi-way valve can first connect the water inlet and the first port to introduce water medium into the chamber 11. After the target amount of water medium is introduced, the water inlet and the first port can be disconnected, and the water medium can be cooled by the heat exchanger 20. The stirrer 30 works at the same time to form a uniform ice storage layer in the chamber 11. At this time, the multi-way valve connects the water inlet and the second port to introduce water into the water supply component 40. The ice storage layer can cool the water in the water supply component 40 and increase the outlet temperature of the first cup of cold water.
