DETAILED DESCRIPTION

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] Combination Figure 1 and Figure 2 According to an embodiment of the present invention, a refrigeration assembly 100 can be used for drinking water equipment. The refrigeration assembly 100 includes: a cold storage box 10, the cold storage box 10 has a chamber 11, a liquid inlet 15 and a liquid outlet 16, the liquid inlet 15 and the liquid outlet 16 are connected to the chamber 11, the liquid inlet 15 can be used to pass a medium into the chamber 11, and the liquid outlet 16 can be used to discharge the medium in the chamber 11. Exemplarily, the medium can be water, a refrigerant, etc. By providing the liquid inlet 15 and the liquid outlet 16, it is convenient to add a medium to the chamber 11 and discharge the medium in the chamber 11.

[0039] Combination Figure 2 The refrigeration assembly 100 further includes a heat exchanger 20, which is configured to cool the medium in the chamber 11. Specifically, the heat exchanger 20 can absorb the heat of the medium to cool the medium.

[0040] Combination Figure 2 , the refrigeration assembly 100 further includes an agitator 30, which is configured to stir the medium in the chamber 11. By setting the agitator 30 to stir the medium in the chamber 11, the temperature of the medium in the chamber 11 can be made more uniform, and a large temperature difference between the medium close to the heat exchanger 20 and the medium far from the heat exchanger 20 can be avoided. In addition, it can be understood that during the heat exchange process of the heat exchanger 20, the medium with a lower temperature tends to flow downward, which leads to a lower temperature of the medium below the chamber 11 and a higher temperature above the chamber 11. For example, when the medium is water, the water below the chamber 11 is more likely to freeze than the water above. By setting the agitator 30 to stir the water in the chamber 11, the flow of water in the chamber 11 is accelerated, and the problem of local freezing can be avoided.

[0041] Combination Figure 2 The refrigeration assembly 100 further includes a water delivery member 40, which has a flow channel for liquid circulation. At least a portion of the water delivery member 40 is disposed in the chamber 11 and exchanges heat with the medium in the chamber 11. Specifically, the liquid flows through the water delivery member 40, and the medium in the chamber 11 absorbs the heat of the liquid, thereby cooling the liquid. Exemplarily, the water delivery member 40 can be used to deliver liquids such as purified water, domestic water, and beverages.

[0042] Specifically, the medium can be introduced into the chamber 11 through the liquid inlet 15, and the heat of the medium can be absorbed by the heat exchanger 20 to achieve cooling of the medium. In the process of cooling the medium, the heat exchanger 20 stirs the medium through the stirrer 30 to make the temperature of the medium in the chamber 11 more uniform. When the liquid flows in the flow channel of the water conveying member 40, the medium absorbs the heat of the liquid to achieve cooling of the liquid. In other words, the liquid in the water conveying member 40 is cooled by indirectly cooling the temperature with the heat exchanger 20, which can avoid the liquid directly contacting the heat exchanger 20 to contaminate the liquid and maintain the purity of the liquid. In addition, by setting the stirrer 30 to stir the medium in the chamber 11, the temperature of the medium in the chamber 11 can be made more uniform, and the medium can be prevented from freezing due to low local temperature, which causes local freezing in the water conveying member 40 to block the flow channel of the water conveying member 40.

[0043] According to the refrigeration component 100 of the embodiment of the present invention, the liquid in the water delivery component 40 is indirectly cooled by the heat exchanger 20, and an agitator 30 is provided to stir 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 and causing the liquid in the water delivery pipe to freeze and block the pipeline, and improve the working stability of the drinking water equipment.

[0044] Among them, the heat exchanger 20 is configured to cool the medium in the chamber 11. For example, the heat exchanger 20 can be arranged in the chamber 11, which can improve the heat exchange efficiency of the heat exchanger 20 for the medium; or, the heat exchanger 20 can be arranged outside the chamber 11, for example, the heat exchanger 20 can be embedded in the cold storage box 10.

[0045] Exemplarily, the water delivery member 40 may be a plate-type structure with a flow channel arranged inside the plate; or, the water delivery member 40 may be a tubular structure with a flow channel arranged inside the tubular body.

[0046] In addition, the cold storage box 10 is provided with a liquid inlet 15 and a liquid outlet 16, which are convenient for introducing and discharging the medium in the chamber 11. For example, when the liquid needs to be refrigerated, the medium can be introduced into the chamber 11 through the liquid inlet 15, or when the medium in the chamber 11 is insufficient, the medium can be supplemented into the chamber 11 through the liquid inlet 15; 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 16 to avoid the medium from contacting the heat exchanger 20 for a long time, which affects the service life of the heat exchanger 20. Among them, the medium can be water or a refrigerant, etc., and this application is mainly described by taking water as an example.

[0047] Combination Figure 6 , for example, the drinking water device may be provided with a refrigeration system 1000, the refrigeration system 1000 includes a compressor 200, a condenser 300, a throttling element 400 and the aforementioned refrigeration assembly 100, and the compressor 200, the condenser 300, the throttling element 400 and the heat exchanger 20 are connected to form a loop. Taking water as the refrigerant medium as an example, when the refrigeration system 1000 is working, the heat exchanger 20 absorbs the heat of the water and can gradually cool the water in the chamber 11. At this time, the agitator 30 can work at the same time to prevent the cold water from flowing downward and forming ice cubes below the chamber 11. The agitator 30 can accelerate the flow of water in the chamber 11, so that the water can form an ice storage layer uniformly in the chamber 11, and prevent the phenomenon of local large ice formation, thereby preventing the water in the chamber 11 from freezing and blocking the pipeline during the heat exchange process with the liquid in the water delivery member 40, thereby improving the water output stability of the drinking water device. In addition, by setting water as the medium and stirring the water through the stirrer 30, a uniform ice storage layer can be formed in the chamber 11, so that the amount of ice stored in the chamber 11 is uniform, and the water outlet temperature of the drinking water device can be lower.

[0048] Combination Figure 2 In some embodiments of the present invention, the heat exchanger 20 is disposed in the chamber 11 , which can improve the cooling efficiency of the heat exchanger 20 on the medium in the chamber 11 , thereby improving the cooling efficiency of the liquid in the water delivery member 40 .

[0049] Combination Figure 2 and Figure 4 Furthermore, the heat exchanger 20 is arranged around the water conveying member 40, that is, the water conveying member 40 is arranged on the inside and the heat exchanger 20 is arranged on the outside. The heat exchanger 20 cools the medium and then cools the liquid in the water conveying member 40. The water conveying member 40 is arranged on the inside, which makes it easier for the medium to cool the water conveying member 40, thereby improving the cooling efficiency of the liquid in the water conveying member 40.

[0050] Combination Figure 2 and Figure 4In some embodiments of the present invention, the water delivery member 40 is arranged around the stirrer 30, so that the medium inside the water delivery member 40 can be stirred by the stirrer 30, so as to improve the temperature uniformity of the medium inside the water delivery member 40, and avoid the local temperature of the medium being too low, causing the liquid in the water delivery pipe to freeze and block the pipeline. In addition, the heat exchanger 20 is arranged around the stirrer 30, so that the medium inside the heat exchanger 20 can be stirred by the stirrer 30, so as to improve the temperature uniformity of the medium inside the heat exchanger 20, and avoid the local temperature of the medium being too low, causing the liquid in the water delivery pipe to freeze and block the pipeline.

[0051] Combination Figure 2 and Figure 4 In some embodiments of the present invention, the heat exchanger 20 is disposed in the chamber 11, the heat exchanger 20 is disposed around the water delivery member 40, and the water delivery member 40 is disposed around the agitator 30. The agitator 30, the water delivery member 40 and the heat exchanger 20 are arranged in sequence from the inside to the outside, so that the overall structure of the refrigeration assembly 100 is compact, the refrigeration efficiency of the liquid is improved, and the problem of local low temperature in the medium is avoided.

[0052] Exemplarily, the agitator 30 can be set at the center of the chamber 11 to improve the stirring efficiency of the medium in the chamber 11, avoid the problem of local low temperature of the medium, make the temperature of the medium in the chamber uniform, and thereby improve the cooling efficiency of the liquid in the water delivery member 40.

[0053] Combination Figure 2 and Figure 4 In some embodiments of the present invention, the stirrer 30 is arranged in the up-down direction, wherein the water delivery member 40 spirally extends in the up-down direction, so as to increase the contact area between the water delivery member 40 and the medium in the chamber 11, and improve the cooling efficiency of the liquid in the water delivery member 40. It can be understood that after the medium in the chamber 11 is cooled by the heat exchanger 20, the medium with low temperature tends to flow to the bottom of the chamber 11, and the stirrer 30 is arranged in the up-down direction, so as to increase the flow of the medium in the up-down direction by stirring, and improve the uniformity of the medium temperature.

[0054] In addition, the heat exchanger 20 includes a plurality of heat exchange sections distributed in the up and down directions, the heat exchange sections extend in the direction surrounding the agitator 30, and the plurality of heat exchange sections are connected, so as to increase the contact area between the heat exchanger 20 and the medium, thereby improving the cooling efficiency and uniformity of the heat exchanger 20 for the medium, and the heat exchange sections extend in the direction surrounding the agitator 30, thereby further improving the temperature uniformity of the medium in the chamber 11.

[0055] Combination Figure 1In some embodiments of the present invention, the water delivery member 40 has a water inlet 41 and a water outlet 42, and the water inlet 41 and the water outlet 42 are connected to the flow channel. Specifically, the liquid can enter the flow channel through the water inlet 41 and flow out of the flow channel through the water outlet 42. The water inlet 41, the water outlet 42 and the liquid inlet 15 are arranged on the same side of the cold storage box 10, which is convenient for the pipeline connection of the refrigeration assembly 100, the installation of the drinking water equipment, and the layout of the drinking water equipment is compact.

[0056] Exemplarily, the medium can be water, and the water delivery component 40 can be used to transport water, that is, the medium in the chamber 11 and the liquid transported in the water delivery component 40 can be the same fluid. The drinking water equipment can include a water inlet component, through which the medium can be introduced into the chamber 11 and the fluid can be supplied to the water delivery component, thereby simplifying the piping and structure of the drinking water equipment.

[0057] For example, the drinking water equipment may include a filter element. After being filtered, the water may be provided with a first branch to enter the chamber 11 as a heat exchange medium, and a second branch may be provided to supply the water to the water delivery member 40, where the water is cooled by the refrigeration component 100 and then discharged from the water outlet. By arranging the water inlet 41, the liquid inlet 15 and the water outlet 42 on the same side of the cold storage box 10, the pipeline connection of the refrigeration component 100 can be facilitated, making the structure of the drinking water equipment compact.

[0058] At least a portion of the water delivery member 40 is disposed in the chamber 11 , and the water inlet 41 and the water outlet 42 can extend out of the chamber 11 to facilitate the pipe connection of the refrigeration assembly 100 .

[0059] Combination Figure 2 In some embodiments of the present invention, the cold storage box 10 includes a barrel body 12 and a cover body 13, the cover body 13 is covered on the upper end of the barrel body 12, the liquid inlet 15 is provided on the cover body 13, and the liquid outlet 16 is provided on the barrel body 12. That is, the liquid inlet 15 is provided at the upper end of the cold storage box 10, and the liquid outlet 16 is provided at the lower end of the cold storage box 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.

[0060] Combination Figure 2 In some embodiments of the present invention, the refrigeration component 100 further includes: a liquid level monitoring component 50, which is configured to monitor the liquid level in the chamber 11. When the medium is introduced into the chamber 11 through the liquid inlet 15, the liquid level of the medium in the chamber 11 can be monitored by the liquid level monitoring component 50. For example, when the liquid level reaches an upper limit value, the valve can be controlled to stop introducing the medium into the chamber 11. When the liquid level is lower than a lower limit value, the valve can be controlled to introduce the medium into the chamber 11, thereby improving the working stability of the refrigeration component 100.

[0061] Exemplarily, the liquid level monitoring component 50 may be a float, an ultrasonic liquid level meter, or the like.

[0062] In some embodiments of the present invention, the liquid level monitoring component 50 includes a float, which is disposed in the chamber 11 and is 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 liquid inlet 15. The float can accurately track the change of the water level in the chamber 11, and can prevent the low temperature environment in the chamber 11 from affecting the performance of the float, so that the float can stably monitor the liquid level in the chamber 11.

[0063] Combination Figure 3 In some embodiments of the present invention, in the projection along the up-down direction, the distance between the liquid level monitoring component 50 and the agitator 30 is L0, the minimum distance between the liquid level monitoring component 50 and the water delivery component 40 is L1, the minimum distance between the liquid level monitoring component 50 and the heat exchanger 20 is L2, and the distance between the liquid level monitoring component 50 and the inner circumference of the chamber 11 is L3, wherein L0≥L1; or, L0≥L2; or, L0≥L3. Specifically, the water delivery component 40 may be configured to have different structures and shapes, and therefore, different positions of the water delivery component 40 have different distances from the liquid level monitoring component 50, and L1 is the minimum distance between the liquid level monitoring component 50 and the water delivery component 40; the heat exchanger 20 may also be configured to have different structures and shapes, and different positions of the heat exchanger 20 may have different distances from the liquid level monitoring component 50, and L2 is the minimum distance between the liquid level monitoring component 50 and the heat exchanger 20.

[0064] It can be understood that the agitator 30 will stir the medium in the chamber 11 during operation, causing the liquid level in the chamber 11 to change. The distance between the liquid level monitoring component 50 and the agitator 30 is relatively large, which prevents the agitator 30 from affecting the monitoring result of the liquid level monitoring component 50 during operation. In addition, the water supply component 40, the heat exchanger 20 and the chamber 11 are fixed in relative position. Therefore, by optimizing the position of the components, the liquid level monitoring component 50 is closer to the water supply component 40, the heat exchanger 20 and the chamber 11, and the distance between the liquid level monitoring component 50 and the agitator 30 is relatively large, which can improve the accuracy of the monitoring result of the liquid level monitoring component 50 and improve the working stability of the refrigeration component 100.

[0065] Combination Figure 5In some embodiments of the present invention, the agitator 30 includes a driving member 31 and a stirring member 32. At least a portion of the stirring member 32 is disposed in the chamber 11. The driving member 31 is in transmission connection with the stirring member 32, and is used to drive the stirring member 32 to stir the medium in the chamber 11. Specifically, the driving member 31 works to drive the stirring member 32 to rotate, so that the stirring member 32 can stir the medium in the chamber 11, and avoid the phenomenon of local freezing due to uneven temperature of the medium in the chamber 11. Exemplarily, the rotation speed of the stirring member 32 can be adjusted by adjusting the rotation speed of the driving member 31, or the stirring frequency of the stirring member 32 can be adjusted by adjusting the operating frequency of the driving member 31. For example, a temperature detection member 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 driving member 31 can be operated at a higher rotation speed. When the temperature is close to the target temperature, the rotation speed of the driving member 31 can be reduced.

[0066] Combination Figure 5 Furthermore, the cold storage box 10 includes a barrel body 12 and a cover body 13. The cover body 13 is covered on the upper end of the barrel body 12, and the driving member 31 is connected to the cover body 13. By connecting the driving member 31 to the cover body 13, the installation of the agitator 30 is facilitated, and the subsequent maintenance of the agitator 30 is facilitated, and it is avoided that a structure for installing the driving member 31 is set in the barrel body 12, which affects the sealing performance of the barrel body 12.

[0067] Combination Figure 5 In some embodiments of the present invention, the cover body 13 includes an inner cover 131 and an outer cover 132, and 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, wherein the inner cover 131 covers the upper end of the barrel body 12, and the inner cover 131 is provided with a positioning groove for positioning the driving member 31, which improves the installation efficiency and structural stability of the driving member 31. In addition, the driving member 31 is arranged between the inner cover 131 and the outer cover 132, and the inner cover 131 and the outer cover 132 cooperate to protect the driving member 31, improve the structural stability of the driving member 31, and prevent the fluid from entering the driving member 31, so that the driving member 31 can stably drive the stirring member 32 to stir the medium in the chamber 11.

[0068] Combination Figure 5 In some embodiments of the present invention, the cold storage box 10 includes a barrel body 12 and a cover body 13, and the cover body 13 is covered on the barrel body 12. The barrel body 12 includes an inner barrel 121 and an outer barrel 122, and the inner barrel 121 is arranged inside the outer barrel 122. A first thermal insulation layer 123 is arranged between the inner barrel 121 and the outer barrel 122. The first thermal insulation layer 123 can prevent the loss of cold and the external heat from entering the chamber 11, so that the chamber 11 maintains a lower temperature environment and improves the refrigeration efficiency.

[0069] In addition, the cover body 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 is covered on the barrel body 12, and a second thermal insulation layer 133 is provided between the inner cover 131 and the outer cover 132. The second thermal insulation layer 133 can prevent the loss of cold and the entry of external heat into the chamber 11, so that a lower temperature environment is maintained in the chamber 11, thereby improving the refrigeration efficiency.

[0070] In addition, the cold storage box 10 is provided with a barrel body 12 and a cover body 13, and the heat exchanger 20, the agitator 30, and the water delivery member 40 can all be connected to the cover body 13, which facilitates the installation of the refrigeration assembly 100. During the specific installation, the agitator 30, the heat exchanger 20, and the water delivery member 40 can be first installed to the cover body 13, and then the cover body 13 is connected to the barrel body 12, so as to improve the installation efficiency of the refrigeration assembly 100. When assembling the agitator 30, the driving member 31 can be first installed between the inner cover 131 and the outer cover 132, and then the agitator 32 can be connected to the driving member 31.

[0071] In some embodiments of the present invention, the heat exchanger 20 is disposed in the chamber 11 and is separated 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 cold caused by direct contact between the heat exchanger 20 and the inner surface of the chamber 11.

[0072] Combination Figure 2 Furthermore, a plurality of ribs 14 are provided on the inner circumferential surface of the chamber 11, and the plurality of ribs 14 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. Arranging 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 so that the chamber 11 can 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, facilitate the flow of the medium in the gap between the inner surface of the chamber 11 and the heat exchanger 20, and improve the cooling efficiency of the heat exchanger 20 for the medium.

[0073] Combination Figure 6 The present invention also provides a refrigeration system 1000 for drinking water equipment, the refrigeration system 1000 includes: a compressor 200, a condenser 300, a throttling element 400 and the aforementioned refrigeration assembly 100, wherein the compressor 200, the condenser 300, the throttling element 400 and the heat exchanger 20 are connected to form a loop.

[0074] Furthermore, the cold storage box 10, the compressor 200, and the condenser 300 are arranged in sequence along the up-down direction, optimizing the layout of the refrigeration system 1000, making the overall structure of the refrigeration system 1000 compact, and improving space utilization.

[0075] The drinking water equipment according to the embodiment of the present invention includes the aforementioned refrigeration assembly 100 , or includes the aforementioned refrigeration system 1000 .

[0076] Exemplarily, the water delivery member 40 may have a water inlet 41 and a water outlet 42 .

[0077] 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 refrigeration component 100, the water outlet stability of the water outlet component can be improved.

[0078] The drinking water equipment may further include a drainage component, which is used to discharge waste water. The liquid outlet 16 is connected to the drainage component, and the medium in the chamber 11 can be discharged through the drainage component to avoid the medium being stored in the chamber 11 for a long time, which affects the service life of the heat exchanger 20.

[0079] In addition, the drinking water device may include a water inlet assembly. For example, the water inlet assembly may supply water medium into the chamber 11 and pass water into the water delivery member 40. Specifically, the water inlet assembly may include a multi-way valve. The multi-way valve has a water inlet interface, a first interface, and a second interface. The water inlet interface may be connected to the water inlet pipeline. The first interface is connected to the liquid inlet 15, and the second interface is connected to the water inlet 41 of the water delivery member 40. The multi-way valve may control the water inlet interface to selectively connect the first interface and the second interface. For example, when water needs to be cooled, the multi-way valve may first connect the water inlet interface and the first interface, and pass water medium into the chamber 11. After the target amount of water medium is passed, the water inlet interface and the first interface may be disconnected, and the water medium is cooled by the heat exchanger 20. The agitator 30 works at the same time to form a uniform ice storage layer in the chamber 11. The multi-way valve connects the water inlet interface and the second interface, and passes water into the water delivery member 40. The ice storage layer may cool the water in the water delivery member 40 and increase the outlet water temperature of the first cup of cold water.
