DETAILED DESCRIPTION

[0042] 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.

[0043] Combination Figure 1 and Figure 2The refrigeration assembly 100 of the drinking water equipment according to the embodiment of the present invention comprises: a cold storage box 10, the cold storage box 10 has a chamber 11, a liquid inlet 12 and a liquid outlet 13, the liquid inlet 12 and the liquid outlet 13 are connected to the chamber 11; the liquid inlet 12 can be used to introduce a medium into the chamber 11, and the liquid outlet 13 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 12 and the liquid outlet 13, it is convenient to add a medium to the chamber 11 and discharge the medium in the chamber 11.

[0044] Combination Figure 1 and Figure 2 The refrigeration component 100 also includes a heat exchanger 20, which is disposed in the chamber 11 and 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 to cool the medium. The heat exchanger 20 is disposed in the chamber 11 to directly contact the medium and cool the medium, which can improve the cooling efficiency of the heat exchanger 20 for the medium. In addition, the cold storage box 10 has a liquid inlet 12 and a liquid outlet 13 connected to the chamber 11. After the refrigeration work is completed, or when the drinking water device is not used for a long time, the medium in the chamber 11 can be discharged through the liquid outlet 13 to avoid long-term contact between the medium and the heat exchanger 20, which affects the service life of the heat exchanger 20.

[0045] Combination Figure 1 and 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 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 the water in the chamber 11 is accelerated, the contact area between the water in the chamber 11 and the heat exchanger 20 is increased, the cooling efficiency is improved, and the problem of local freezing is avoided.

[0046] 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 in the water delivery member 40, thereby cooling the liquid. Exemplarily, the water delivery member 40 can be used to transport liquids such as purified water, domestic water, and beverages. By arranging the water delivery member 40 to exchange heat with the medium in the chamber 11, direct contact between the liquid and the heat exchanger 20 can be avoided to cause contamination.

[0047] Combination Figure 2 and Figure 3 , wherein the stirrer 30 includes a driving member 31 and a stirring member 32, the stirring member 32 is disposed in the chamber 11, and the stirring member 32 includes a transmission shaft 321 and blades 322, the transmission shaft 321 is transmission-connected to the driving member 31, and the blades 322 are connected to the transmission shaft 321 and extend along the length direction of the transmission shaft 321. Specifically, when the driving member 31 works, the transmission shaft 321 drives the blades 322 to rotate, so that the blades 322 can stir the medium in the chamber 11, thereby preventing the uneven temperature of the medium in the chamber 11 from affecting the cooling efficiency of the liquid in the water delivery member 40. The blades 322 extend along the length direction of the transmission shaft 321, which can enhance the structural strength of the blades 322 and the stability during the rotation process, and improve the stirring efficiency of the medium.

[0048] It should be noted that the blades 322 extend along the length direction of the transmission shaft 321 , and the extension direction of the blades 322 may be completely consistent with the extension direction of the transmission shaft 321 , or the blades 322 may have a certain inclination angle relative to the length direction of the transmission shaft 321 .

[0049] For example, the rotation speed of the stirring member 32 can be adjusted by adjusting the rotation speed of the driving member 31, or the rotation frequency of the stirring member 32 can be adjusted by adjusting the operation 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.

[0050] Specifically, the medium can be introduced into the chamber 11 through the liquid inlet 12, 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. That is, the liquid in the water conveying member 40 and the heat exchanger 20 are cooled by indirect cooling, 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, the stirrer 30 is provided with blades 322 extending along the length direction of the transmission shaft 321, which can improve the stirring efficiency of the medium in the chamber 11, make the temperature of the medium more uniform, avoid the local low temperature of the medium, and cause local ice in the water conveying member 40 to block the flow channel of the water conveying member 40, so that the outlet water temperature of the water conveying member 40 is more stable.

[0051] 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, causing the liquid in the water delivery component 40 to freeze and block the pipeline, and stabilize the water outlet temperature of the water delivery component 40.

[0052] Exemplarily, the water delivery member 40 may be a plate structure with a flow channel arranged inside the plate; or, the water delivery member 40 may be configured as a tubular structure with a flow channel arranged inside the tube, for example, the water delivery member 40 may be configured as a stainless steel water pipe.

[0053] In addition, the cold storage box 10 has a liquid inlet 12 and a liquid outlet 13, which are convenient for introducing and discharging the medium into 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 12, or when the medium in the chamber 11 is insufficient, the medium can be supplemented into the chamber 11 through the liquid inlet 12; after the refrigeration work is completed, 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 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 the medium as water as an example.

[0054] Exemplarily, the drinking water device may be provided with a refrigeration system 1000, which 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. 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 gradually cools the water in the chamber 11. At this time, the agitator 30 may work at the same time to prevent the cold water from flowing downward and forming ice cubes below the chamber 11. The agitating blades 322 can accelerate the flow of water in the chamber 11 to prevent the occurrence 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, so that the water output of the water delivery member 40 is more stable. In addition, by setting water as the medium and stirring the water through the stirring member 32, a uniform ice storage layer can be formed in the chamber 11, which can make the water outlet temperature of the drinking water device lower.

[0055] In addition, when the temperature of the medium in the chamber 11 differs greatly from the target temperature, the compressor 200 can be controlled to operate at a higher frequency to improve the refrigeration efficiency of the heat exchanger 20. At this time, the agitator 30 can be controlled to rotate at a higher speed to avoid the local temperature of the medium being too low during the rapid cooling process. When the temperature of the medium in the chamber 11 differs little from the target temperature, the compressor 200 can be controlled to operate at a lower frequency. At this time, the agitator 30 can be controlled to rotate at a lower speed. Of course, the operating frequency of the agitator 30 can also be adjusted according to the temperature of the medium in the chamber 11. For example, when the water temperature T in the chamber 11 satisfies 1°C≤T<5°C, the agitator 30 can be operated at a frequency of 4 minutes on and 1 minute off. When the water temperature T in the chamber 11 satisfies -2.5°C≤T<1°C, the agitator 30 can be operated at a frequency of 2 minutes on and 1 minute off to avoid the local temperature in the chamber 11 being too low and causing large ice to form.

[0056] Combination Figure 3 In some embodiments of the present invention, the blades 322 are inclined along the axis of the transmission shaft 321 and around the circumference of the transmission shaft 321, thereby reducing the impact between the medium and the blades 322, thereby reducing the resistance of the blades 322 during the stirring process. At the same time, the resistance to stirring is reduced, and the noise during the stirring process can also be reduced.

[0057] Combination Figure 3 In some embodiments of the present invention, the blades 322 include a plurality of blades 322 arranged at intervals along the circumferential direction of the transmission shaft 321. By providing a plurality of blades 322, during the rotation of the stirring member 32, the plurality of blades 322 simultaneously stir the medium, which can improve the stirring effect on the medium and further improve the stirring uniformity of the medium in the chamber 11. For example, the number of the blades 322 can be two, three, four, five, etc.

[0058] In some embodiments of the present 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 transmission shaft 321 during the rotation of the blade 322. The helix angle of the blade 322 is greater than 0°, which can reduce the impact between the blade 322 and the medium and thus reduce the resistance during the stirring process. At the same time, the helix angle of the blade 322 is less than or equal to 30°, which avoids excessive distortion of the blade 322, increases the force on the blade 322, and easily causes the medium to flow too low in the radial direction, causing uneven stirring of the medium, and affecting the temperature uniformity of the medium in the chamber 11. By controlling the helix angle between 0° and 30°, it is possible to reduce the resistance of the blade 322 during the stirring process, reduce the noise during the stirring process, and improve the uniformity of the stirring. Exemplarily, the helix angle can be 10°, 15°, 16°, 19°, 20°, 25°, etc.

[0059] Preferably, the helix angle is 15°, which can reduce the resistance of the blade 322 during the stirring process, improve the stirring uniformity of the medium in the chamber 11, and reduce the noise during the stirring process.

[0060] In some embodiments of the present invention, the stirring member 32 extends in the up-down direction. 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. The stirrer 30 is arranged in the up-down direction, which is convenient for mixing the medium in the up-down direction through the stirring of the blades 322, thereby improving the uniformity of the medium temperature.

[0061] 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.

[0062] Exemplarily, the refrigeration assembly 100 may be provided with a liquid level monitoring component 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 thereby avoid excessive fluctuation of the medium water level affecting the monitoring result of the liquid level monitoring component 50.

[0063] In some embodiments, the lower end of the blade 322 is flush with the lower end of the transmission shaft 321, because the medium with lower temperature can easily flow to the bottom of the chamber 11, so that the medium below the chamber 11 can be stirred by the stirring member 32 to improve the stirring uniformity of the medium.

[0064] Combination Figure 3 In some embodiments of the present invention, the transmission shaft 321 extends in the up-down direction, and the outer peripheral surface of the lower part of the transmission shaft 321 is configured as a conical surface that gradually shrinks from top to bottom, which can reduce the resistance of the stirring member 32 during the stirring process and improve the stirring efficiency of the medium.

[0065] Combination Figure 4 In some embodiments of the invention, the distances between different positions of the outer edge 322a of the blade 322 and the axis of the transmission shaft 321 are the same, which can improve the stability of the blade 322 during the stirring process.

[0066] Combination Figure 3 and Figure 4In some embodiments of the present invention, the transmission shaft 321 extends in the up-down direction, the outer peripheral surface of the lower part of the transmission shaft 321 is configured as a conical surface that gradually shrinks in the direction from top to bottom, and the distance between the outer edge 322a of the blade 322 and the axis of the transmission shaft 321 is the same at different positions. Relatively speaking, the distance from the inner edge 322b of the blade 322 at the lower end to the outer edge 322a is greater than the distance from the inner edge 322b of the blade 322 at the upper end to the outer edge 322a. This arrangement can make the area of ​​the blade 322 at the lower end larger. Combined with the above, when the heat exchanger 20 cools the medium, the medium with a lower temperature is more likely to flow downward. The blade 322 at the lower end is larger, which is convenient for increasing the contact area between the blade 322 at the lower end and the medium, thereby increasing the flow rate of the medium below by stirring, so that the temperature of the medium in the chamber 11 is more uniform. When the medium is water, the water below the chamber 11 is more likely to freeze than the water above. Through the design of the blade 322 and the transmission shaft 321, the problem of local freezing of the water below can be avoided.

[0067] Combined with the above, during the cooling process of the medium by the heat exchanger 20, the medium with a lower temperature tends to flow downward. The blades 322 are inclined around the circumference of the transmission shaft 321 along the axis of the transmission shaft 321, and the blades 322 include a plurality of blades arranged at intervals along the circumference of the transmission shaft 321, and a stirring channel can be constructed between adjacent blades 322. In addition, the outer peripheral surface of the lower part of the transmission shaft 321 gradually shrinks in the direction from top to bottom, and the different positions of the outer edge 322a of the blade 322 are at the same distance from the axis of the transmission shaft 321. The blades 322 at the lower end have a larger area, and the lower end of the stirring member 32 has a larger stirring channel, so that the stirring member 32 has a greater stirring efficiency for the fluid below the chamber 11 during the stirring process. Therefore, the flow rate of the fluid below the chamber 11 is greater, which can make the medium in the chamber 11 more evenly stirred, and avoid the problem of the medium temperature below the chamber 11 being too low and forming large ice.

[0068] Combination Figure 5In some embodiments of the present invention, the distance between the outer edge 322a of the blade 322 and the axis of the transmission shaft 321 is L1, the distance between the inner edge 322b of the blade 322 and the axis of the transmission shaft 321 is L2, and the maximum radius size of the transmission shaft 321 is L0, wherein 1.4≤(L1-L2) / L0≤1.7. During the rotation of the stirring member 32, the blade 322 is driven by the transmission shaft 321 to stir the fluid, and the transmission shaft 321 can transmit torque. By designing the size of the blade 322 and the size of the transmission shaft 321 within a reasonable range, the stirring efficiency of the blade 322 and the structural strength of the stirring member 32 can be improved. Among them, (L1-L2) / L0 is greater than or equal to 1.4, and the stirring member 32 is convenient to accelerate the flow of the medium through the blade 322 during the rotation process, improve the temperature uniformity of the medium in the chamber 11, and improve the performance of the stirring member 32. In addition, (L1-L2) / L0 is less than or equal to 1.7, so as to prevent the blade 322 from deforming during the stirring process. Exemplarily, (L1-L2) / L0 can be set to 1.4, 1.51, 1.52, 1.55, 1.6, etc.

[0069] Combination Figure 5 and Figure 6 In some embodiments of the present invention, the distance between the outer edge 322a of the blade 322 and the axis of the transmission shaft 321 is L1, and the distance between the inner circumference of the chamber 11 and the axis of the transmission 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 be prevented from occupying too much space in the chamber 11. Exemplarily, 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, so as to avoid the distance between the blade 322 and the chamber 11 being too small, so that the agitator 30 occupies too much space in the chamber 11, and the noise of the fluid during the stirring process is large, and L1 / L3 is less than or equal to 0.25, so as to avoid the blade 322 being unable to stir the medium in the chamber 11 to flow evenly, affecting the uniformity of stirring.

[0070] Combination Figure 2 and Figure 6In 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 12, 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 the upper limit value, the valve can be controlled to stop introducing the medium into the chamber 11. When the liquid level is lower than the 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. Among them, in the projection along the up and down directions, the minimum spacing between the liquid level monitoring component 50 and the transmission shaft 321 is L4, 0.2≤L1 / L4≤0.3. By setting the size of the blade 322 and the distance from the liquid level monitoring component 50 within a reasonable range, the influence of the blade 322 on the water level during the stirring process is reduced, thereby affecting the monitoring result of the liquid level monitor.

[0071] Illustratively, the liquid level monitor may be a float, an ultrasonic liquid level meter, or the like.

[0072] Combination Figure 5 and Figure 6 Optionally, the distance between the outer edge 322a of the blade 322 and the axis of the transmission shaft 321 is L1, and the minimum distance between the water delivery member 40 and the axis of the transmission shaft 321 is L5, 0.4≤L1 / L5≤0.5. The water delivery member 40 can be set to different structures and shapes. Therefore, different positions of the water delivery member 40 have different distances from the axis of the transmission shaft 321. L5 is the minimum distance between the water delivery member 40 and the axis of the transmission shaft 321. A certain distance is set between the stirring member 32 and the water delivery member 40 to avoid interference between the stirring member 32 during the stirring process, affecting the stirring effect and generating noise. By setting L1 / L5 to a reasonable distance, on the one hand, it is easy to improve the uniformity of stirring of the stirring member 32, and can reduce the noise during the stirring process.

[0073] Combination Figure 6 Optionally, the distance between the outer edge 322a of the blade 322 and the axis of the transmission shaft 321 is L1, and the minimum distance between the heat exchanger 20 and the axis of the transmission shaft 321 is L6, 0.2≤L1 / L6≤0.3. The heat exchanger 20 can be set to different structures and shapes, and the distances between different positions of the heat exchanger 20 and the axis of the transmission shaft 321 may be different. L6 is the minimum distance between the heat exchanger 20 and the axis of the transmission shaft 321. A certain distance is set between the stirring member 32 and the heat exchanger 20 to avoid interference between the stirring member 32 during the stirring process, affecting the stirring effect, and generating noise. By setting L1 / L6 to a reasonable distance, on the one hand, it is easy to improve the uniformity of stirring of the stirring member 32, and can reduce the noise during the stirring process.

[0074] 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 12. The float can accurately track the change of the water level in the chamber 11, and can avoid affecting the performance of the float when the temperature in the chamber 11 decreases, so that the float can stably monitor the liquid level in the chamber 11.

[0075] Combination Figure 6 In some embodiments of the invention, in the projection along the up-down direction, the distance between the liquid level monitoring component 50 and the outer edge of the blade 322 is D0, the minimum distance between the liquid level monitoring component 50 and the water delivery component 40 is D1, the distance between the liquid level monitoring component 50 and the heat exchanger 20 is D2, and the distance between the liquid level monitoring component 50 and the inner circumference of the chamber 11 is D3, wherein D0≥D1; or, D0≥D2; or, D0≥D3. Specifically, the water delivery component 40 can be set to different structures and shapes, so 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 can also be set to 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.

[0076] It can be understood that when the stirring member 32 is in operation, the blades 322 will stir the medium in the chamber 11, causing the liquid level in the chamber 11 to change. The distance between the liquid level monitoring member 50 and the outer edge of the blade 322 is relatively large, so as to prevent the blade 322 from affecting the monitoring result of the liquid level monitor during the rotation. In addition, the relative positions of the water supply member 40, the heat exchanger 20 and the chamber 11 are fixed. Therefore, by optimizing the position of the components, the liquid level monitoring member 50 is brought closer to the water supply member 40, the heat exchanger 20 and the chamber 11, and the distance between the liquid level monitoring member 50 and the stirrer 30 is relatively large, which can improve the accuracy of the monitoring result of the liquid level monitoring member 50 and improve the working stability of the refrigeration assembly 100.

[0079] For example, the drinking water device may include a filter element, and 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 element 40 so that 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 12 and the water outlet 42 on the same side of the cold storage tank 10, it is convenient to connect the pipeline of the refrigeration component 100, making the structure of the drinking water device more compact. In addition, the water inlet 41 and the liquid inlet 12 may face the same side, and the water outlet 42 may face the other side, so as to facilitate the connection of the pipeline of the refrigeration component 100 and optimize the flow path of the drinking water device.

[0080] 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 .

[0085] Exemplarily, the stirring member 32 may be disposed at the center of the chamber 11 to improve the uniformity of stirring the medium in the chamber 11 and avoid the problem of local low temperature of the medium.

[0086] Combination Figure 8 In some embodiments of the present invention, the stirring member 32 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.

[0092] Optionally, the heat exchanger 20 is separated from the inner surface of the chamber 11, and 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.

[0093] Furthermore, the inner circumferential surface of the chamber 11 is provided with a plurality of ribs, which are distributed along the circumference of the chamber 11, and the ribs separate the heat exchanger 20 from the inner surface of the chamber 11.
