[0042] The present invention provides a cooling fan, which can improve the effect of continuously cooling air.

[0043] See also Figures 1 to 3In one embodiment of the cooling fan 10 of the present invention, the cooling fan 10 includes a shell 100, a wet curtain assembly 200, a water tank 300 and a refrigeration device 400, the wet curtain assembly 200 is arranged in the shell 100; the water tank 300 is arranged in the shell 100 and is located below the wet curtain assembly 200, the water tank 300 has a water tank, and the water tank is used to supply water to the wet curtain assembly 200; the refrigeration device 400 is arranged below the wet curtain assembly 200, and the refrigeration device 400 is used to provide ice cubes and / or ice water to the water tank.

[0044] It is understandable that the wet curtain assembly 200 may include a wet curtain frame and a wet curtain arranged on the wet curtain frame, the wet curtain can absorb water provided by the water tank 300, the water in the water tank 300 can be pumped to the wet curtain assembly 200 through a water pump and a water guide pipe, so as to supply water to the wet curtain assembly 200, and the water outlet of the water guide pipe can be arranged at the water inlet end of the wet curtain assembly 200. The cooling fan 10 may also include a fan, which is arranged at one side of the wet curtain assembly 200 to blow air to the wet curtain assembly 200, so that the airflow is humidified after passing through the wet curtain assembly 200, so as to achieve the effect of the cooling fan 10 humidifying the air.

[0045] Furthermore, the water tank 300 is arranged below the wet curtain assembly 200, which is not only convenient for adding water to the water tank of the water tank 300, but also helps to lower the center of gravity of the cooling fan 10, so that the cooling fan 10 is not easy to tip over. In addition, the refrigeration device 400 is used to make ice cubes and / or ice water. The refrigeration device 400 is large in size and heavy in weight. The refrigeration device 400 is arranged below the wet curtain assembly 200, which helps to lower the center of gravity of the cooling fan 10, so that the cooling fan 10 is not easy to tip over, and the stability of the cooling fan 10 when in use is improved.

[0046] Furthermore, the water tank 300 is not only used to supply water to the wet curtain assembly 200, but the water tank 300 can also receive ice cubes and / or ice water provided by the refrigeration device 400, so that the wet curtain assembly 200 and the refrigeration device 400 share a water tank 300. This is beneficial to improve the utilization rate of the water tank 300, making the overall structure of the cold fan 10 more compact, which is beneficial to the manufacture and miniaturization of the cold fan 10.

[0047] Furthermore, the refrigeration device 400 can produce ice cubes and / or ice water in a variety of ways, such as but not limited to: heat exchange by transmitting refrigerant, or by semiconductor refrigeration plates. The specific settings can be made according to needs, and the specific embodiments of this scheme are described in detail later.

[0048] The cooling fan 10 of the present invention includes a shell 100, a wet curtain assembly 200, a water tank 300 and a refrigeration device 400. The wet curtain assembly 200 is arranged in the shell 100, the water tank 300 is arranged in the shell 100 and is located below the wet curtain assembly 200, the water tank 300 has a water tank, the water tank is used to supply water to the wet curtain assembly 200, and the refrigeration device 400 is arranged below the wet curtain assembly 200. The refrigeration device 400 is used to provide ice cubes and / or ice water to the water tank. In this way, the ice cubes and / or ice water produced by the refrigeration device 400 can continuously reduce the water temperature in the water tank, so that the water tank 300 can continuously provide ice water with lower temperature to the wet curtain assembly 200, avoiding the situation that the existing cooling fan 10 needs to add an additional ice crystal box to cool the water. The cooling fan 10 in the present application can continuously cool the air without frequent replacement of the ice crystal box. This solution improves the effect of the cooling fan 10 on continuous cooling of the air.

[0049] In one embodiment, the refrigeration device 400 is disposed in the shell 100 and located above the water tank; or, the refrigeration device 400 is disposed in the shell 100 and located on the side of the water tank, and the refrigeration device 400 is communicated with the water tank.

[0050] It can be understood that when the refrigeration device 400 is arranged in the shell 100 and is located above the water tank, the ice cubes and / or ice water produced by the refrigeration device 400 can fall directly into the water tank, so there is no need to transfer the ice cubes and / or ice water to the water tank, and there is no need to add an additional ice crystal box to cool the water in the water tank. The water tank can continuously provide ice water to the wet curtain assembly 200, which is conducive to simplifying the structure of the refrigeration device 400.

[0051] When the refrigeration device 400 is arranged in the shell 100 and is located on the side of the water tank, the refrigeration device 400 is connected to the water tank, and the ice cubes and / or ice water produced by the refrigeration device 400 can flow into the water tank along the delivery pipe. The refrigeration device 400 and the water tank 300 are arranged side by side below the curtain assembly, which is beneficial to reduce the height of the refrigeration device 400 and improve the structural compactness of the refrigeration device 400.

[0052] In one embodiment, the refrigeration device 400 includes an ice-making component and a refrigeration cycle component (not shown), the refrigeration cycle component is connected to the ice-making component via a refrigerant pipe 470, the refrigeration cycle component is used to transport refrigerant to the ice-making component, and the ice-making component is used to exchange heat with the refrigerant transported by the refrigeration cycle component.

[0053] It is understood that the refrigeration cycle assembly may include a compressor, a condenser and an expansion valve, and the compressor, the condenser, the expansion valve and the ice-making assembly are connected in sequence to form a refrigerant circulation loop. The refrigerant may flow along the refrigerant circulation loop and exchange heat with the ice-making assembly when passing through the ice-making assembly to provide a cold source or a heat source to the ice-making assembly. When the refrigerant is used as a cold source, the ice-making module can make ice cubes and / or ice water; when the refrigerant is used as a heat source, the heat causes the ice cubes to fall off and fall into the water tank.

[0054] That is to say, the refrigeration cycle component can transport refrigerant to the ice-making component, and the refrigerant exchanges heat with the ice-making component to provide a cold source to the ice-making component, so that ice cubes can be made on the ice-making component and / or the temperature of water flowing through the ice-making component can be reduced to form ice water. The ice cubes and / or ice water made by the ice-making component can fall into the water tank to reduce the water temperature in the water tank, thereby continuously providing ice water with lower temperature to the wet curtain component 200, which is beneficial to improving the effect of the cold fan 10 on continuous cooling of the air.

[0055] In one embodiment, the compressor and the condenser are arranged below the wet curtain assembly 200 and arranged side by side, which is conducive to lowering the center of gravity of the cooling fan 10, thereby improving the stability of the cooling fan 10. A cooling fan is provided on the condenser to dissipate heat from the compressor.

[0056] See also Figures 3 to 6 In one embodiment, the ice-making assembly includes an ice-making heat exchanger 410 and an ice-making component 420, the refrigerant pipe 470 connects the ice-making heat exchanger 410 and the refrigeration cycle assembly, the ice-making heat exchanger 410 is thermally connected to the ice-making component 420, and the refrigeration device 400 has an ice-making state and an ice-removing state;

[0057] In the ice-making state, the ice-making heat exchanger 410 transfers cold energy to the ice-making element 420 to make ice cubes on the ice-making element 420;

[0058] In the ice-shedding state, the ice-making heat exchanger 410 transfers heat to the ice-making member 420 , and the ice cubes are separated from the ice-making member 420 and fall into the water tank.

[0059] It can be understood that the refrigerant output by the refrigeration cycle component is input to the ice-making heat exchanger 410, and the ice-making heat exchanger 410 performs heat exchange with the ice-making component 420. The ice-making heat exchanger 410 provides a cold source or a hot source for the ice-making component 420 to transfer the cold or heat to the ice-making component 420; the water in the water tank 300 can be used as a water source for ice cubes, that is, the water in the water tank 300 can also be transported to flow through the ice-making component 420, and the specific method will be described in detail later.

[0060] The refrigeration cycle component is used to transport refrigerant to the ice-making component. In the ice-making state, the refrigerant can be a low-temperature liquid. The low-temperature liquid refrigerant evaporates and absorbs heat to become a gas when passing through the ice-making heat exchanger 410. The gaseous refrigerant flows back to the refrigeration cycle component. The ice-making heat exchanger 410 exchanges heat with the ice-making component 420. At this time, the ice-making heat exchanger 410 is a cold source and transfers the cold energy to the ice-making component 420. The ice-making component 420 absorbs the heat of the surrounding water so that ice cubes can be made on the ice-making component 420.

[0061] When ice making is finished and ice cubes are needed to lower the water temperature, in the de-icing state, the refrigerant can be a high-temperature gaseous state. The high-temperature gaseous refrigerant liquefies and releases heat when passing through the ice-making heat exchanger 410. The liquefied refrigerant flows back to the refrigeration cycle component. The ice-making heat exchanger 410 exchanges heat with the ice-making component 420. At this time, the ice-making heat exchanger 410 is a heat source and transfers heat to the ice-making component 420. The heat transferred to the ice-making component 420 causes a water film to be formed between the ice cubes and the ice-making component 420, and then the ice cubes are separated from the ice-making component 420 and fall into the water tank. The water tank can collect ice cubes and cool the water therein. It can be seen that the refrigeration device 400 in this solution can make ice and de-ice, so that it can continuously provide ice water with a lower temperature to the wet curtain component 200 to improve the effect of the cold fan 10 on the continuous cooling of the air.

[0062] See also Figure 4 In one embodiment, the ice-making component 420 includes a base frame 421 and an ice-making portion 422 . The base frame 421 is arranged in a ring shape to form an accommodating space 423 . The ice-making portion 422 is arranged on the base frame 421 and arranged along the ring direction of the base frame 421 .

[0063] It is understandable that the base frame 421 can be a continuous annular structure, or a segmented annular structure. Of course, the base frame 421 can be an annular structure with a gap, as long as the base frame 421 can form an accommodating space 423. In addition, the annular shape can be circular, square, elliptical, or other regular or irregular shapes, which are not specifically limited here.

[0064] Furthermore, the base frame 421 is formed with a accommodating space 423, which can be used to accommodate other components. For example, the water distribution component 430 of the refrigeration device 400 or other components can be arranged in the accommodating space 423, so that the structure of the ice-making component 420 can be fully utilized to improve space utilization.

[0065] In this embodiment, the refrigeration device 400 also includes a water dividing member 430, which is used to guide water to the ice-making member 420. Part of the water dividing member 430 is arranged in the accommodating space 423, so that the accommodating space 423 of the ice-making member 420 is fully utilized, so that the water dividing member 430 occupies less space outside the ice-making member 420, and the internal space utilization rate of the refrigeration device 400 is high.

[0066] Furthermore, ice cubes can be made on the ice-making part 422, and the ice-making part 422 is arranged in the annular direction of the base frame 421, wherein the ice-making part 422 can be arranged in a continuous shape, or the ice-making part 422 can also be arranged in a segmented manner, which is not specifically limited here. In addition, the entire ice-making part 422 can be arranged in an annular shape, and of course the entire ice-making part 422 can also be arranged in a strip shape, which can be specifically arranged according to the needs of ice making.

[0067] It can be seen that in this solution, the refrigeration device 400 includes an ice-making component 420, and the ice-making component 420 includes a base frame 421 and an ice-making portion 422. The base frame 421 is arranged in an annular shape to form an accommodating space 423; the ice-making portion 422 is arranged on the base frame 421 and arranged along the annular direction of the base frame 421. Among them, the accommodating space 423 is suitable for accommodating other components of the refrigeration device 400, which is conducive to improving the space utilization rate inside the refrigeration device 400; and ice cubes can be made on the ice-making portion 422, and the ice cubes can reduce the water temperature in the water tank 300, so as to continuously provide ice water with a lower temperature to the wet curtain assembly 200, which is conducive to improving the effect of the cold fan 10 on continuous cooling of the air.

[0068] See also Figure 4 In one embodiment, the base frame 421 is formed with an annular mounting groove 425 along its annular direction, and the ice-making heat exchanger 410 is arranged in the annular mounting groove 425; and / or, the ice-making part 422 includes a plurality of ice-making grooves 424 arranged in sequence along the annular direction of the base frame 421, and the notches of the ice-making grooves 424 face the inner side or the outer side of the base frame 421.

[0069] It is understandable that the specific position of the annular mounting groove 425 on the base 421 is not limited, for example but not limited to: the annular mounting groove 425 is set at the top of the base 421; or, the annular mounting groove 425 is set at the outer peripheral side of the base 421; or, the annular mounting groove 425 is set at the inner peripheral side of the base 421; or, the annular mounting groove 425 is set at the bottom of the base 421; or, the annular mounting groove 425 is set in the base 421. The notch of the annular mounting groove 425 can be determined according to the position of the annular mounting groove 425 on the base 421. For example, the notch of the annular mounting groove 425 can be opened upward, of course, it can also be opened downward, or opened outward, or opened inward, which is not specifically limited here. The ice-making heat exchanger 410 is arranged in the annular mounting groove 425, so that the ice-making component 420 can fix the ice-making heat exchanger 410, which is conducive to improving the utilization rate of the ice-making component 420.

[0070] When the ice-making element 420 absorbs the heat of the surrounding water, ice can be formed in the ice-making groove 424. The size and shape of the ice-making groove 424 are not limited. A plurality of ice-making grooves 424 can produce a plurality of ice cubes at one time, and the formed plurality of ice cubes are not easy to stick to each other and are easy to detach.

[0071] When ice making is finished and ice cubes are needed to lower the water temperature, the ice making heat exchanger 410 can provide a heat source for the ice making part 420, and the ice making part 420 performs heat exchange with the ice making heat exchanger 410, so that the ice cubes form a water film between the groove wall of the ice making groove 424 and then fall into the water tank from the notch of the ice making groove 424. The notch of the ice making groove 424 faces the inner side of the base frame 421, that is, the ice cubes in the ice making groove 424 can fall into the water tank toward the inner side of the ice making part 420; the notch of the ice making groove 424 faces the outer side of the base frame 421, that is, the ice cubes in the ice making groove 424 can fall into the water tank toward the outer side of the ice making part 420, so that it is convenient for ice cubes to be formed in the ice making groove 424 and to be detached and dropped from the ice making groove 424.

[0072] In one embodiment, the notch of the annular installation groove 425 is arranged upwards, so that the ice-making heat exchanger 410 can be accurately installed into the annular installation groove 425 from above the base frame 421, so as to improve the installation efficiency.

[0073] In one embodiment, a relief notch 426 is provided on the groove wall of the annular installation groove 425. This arrangement can reduce the limitation of the groove wall of the annular installation groove 425 on the ice-making heat exchanger 410, thereby improving the convenience of installing the ice-making heat exchanger 410.

[0074] In one embodiment, a relief notch 426 is provided at a groove wall corner 428 of the annular mounting groove 425. With such a configuration, when the ice-making heat exchanger 410 is arranged along the annular mounting groove 425, the corner 428 of the annular mounting groove 425 avoids the bending part of the ice-making heat exchanger 410 through the relief notch 426, thereby reducing the interference of the annular mounting groove 425 with the bending part of the ice-making heat exchanger 410, facilitating the rapid installation of the ice-making heat exchanger 410, and also facilitating the reduction of the manufacturing difficulty of the base frame 421.

[0075] See also Figure 4 and Figure 5 In one embodiment, the ice making groove 424 has a guide wall 427 located at the bottom, and the guide wall 427 is tilted downward in the direction of the notch of the ice making groove 424. It can be understood that by tilting the guide wall 427 downward, when the refrigeration device 400 is in the de-icing state, the ice cubes can slide downward along the guide wall 427 by their own gravity and fall from the notch of the ice making groove 424 into the water tank 300, thereby optimizing the structure of the ice making part 420 and making it easy for the ice cubes to fall off. Among them, the guide wall 427 can be a plane, of course, it can also be a curved surface, which is not specifically limited here. The guide wall 427 in this embodiment is a plane tilted downward.

[0076] In one embodiment, the base frame 421 is arranged in a polygonal ring shape, and the base frame 421 includes a plurality of connecting segments connected in sequence, a corner 428 is formed at the connection between two adjacent connecting segments, and the ice-making part 422 forms an avoidance space 429 at the corner 428.

[0077] It is understandable that the base frame 421 is arranged in a polygonal ring shape, so that the structure of the base frame 421 is relatively stable, which is conducive to improving the structural strength of the ice-making member 420. The ice-making portion 422 is arranged along the ring direction of the base frame 421, and the ice-making portion 422 forms an escape space 429 at the corner 428 of the base frame 421, that is, the ice-making portion 422 is a segmented ring structure, and the escape space 429 on the ice-making portion 422 avoids the situation that when multiple ice-making grooves 424 are arranged at the corner 428 of the base frame 421, the multiple ice cubes in the multiple ice-making grooves 424 will interfere with each other during the shedding process and prevent the ice cubes from falling. The escape space 429 on the ice-making portion 422 can improve the smoothness of the ice cubes in the ice-making grooves 424 falling into the water tank 300.

[0078] Specifically, in the present embodiment, the base frame 421 is arranged in a square shape, and the number of connecting sections is 4. Correspondingly, the base frame 421 has 4 corners 428, and the ice-making part 422 forms 4 avoidance spaces 429 at the 4 corners 428. This makes the structure of the ice-making part 420 simple, and the accommodating space 423 formed by the base frame 421 is relatively large, which is conducive to accommodating the components of the refrigeration device 400, thereby improving the space utilization rate inside the refrigeration device 400.

[0079] In one embodiment, the ice-making heat exchanger 410 is disposed on the ice-making part 420 along the annular direction of the base frame 421. In this way, the ice-making heat exchanger 410 is also disposed in an annular shape, which is beneficial to increase the heat exchange area of ​​the ice-making heat exchanger 410 in contact with the base frame 421, thereby facilitating the production of ice cubes on the ice-making part 422.

[0080] In one embodiment, the ice-making heat exchanger 410 is arranged in a ring shape with an opening. It is understandable that the ice-making heat exchanger 410 is arranged in a ring direction of the base frame 421, one end of the ice-making heat exchanger 410 is a refrigerant input end, and the other end of the ice-making heat exchanger 410 is a refrigerant output end, and the refrigerant input end and the refrigerant output end are arranged at intervals, so that the ice-making heat exchanger 410 is arranged in a ring shape with an opening, so that it is convenient to connect the ice-making heat exchanger 410 with the refrigerant pipe 470 to form a refrigerant circulation loop.

[0081] In one embodiment, the refrigeration device 400 further includes a heat conductive member, which is disposed between the groove wall of the annular mounting groove 425 of the base frame 421 and the ice-making heat exchanger 410. It is understandable that the heat conductive member can have a heat conduction effect. When the ice-making heat exchanger 410 is disposed in the annular mounting groove 425 of the base frame 421, there is a gap between the ice-making heat exchanger 410 and the groove wall of the annular mounting groove 425. The gap between the two is filled by the heat conductive member, which can enhance the heat conduction between the two, thereby improving the heat exchange efficiency between the ice-making heat exchanger 410 and the base frame 421. The heat conductive member can be a heat conductive silicone sheet, or heat conductive silicone grease, or heat conductive adhesive, etc., which is not specifically limited here.

[0082] See also Figure 3 and Figure 7 In one embodiment, the ice-making assembly further includes a water diversion member 430, which is disposed between the wet curtain assembly 200 and the water tank, and part of the water diversion member 430 is disposed in the accommodating space 423, and the water diversion member 430 is used to guide the water in the water tank to the ice-making member 420.

[0083] It can be understood that the water distribution member 430 is arranged below the wet curtain assembly 200, and a part of the water distribution member 430 is arranged in the accommodating space 423, so that the accommodating space 423 of the ice-making member 420 is fully utilized, so that the water distribution member 430 occupies less space outside the ice-making member 420, and the space utilization rate of the refrigeration device 400 is high; the other part of the water distribution member 430 can be connected to the pumping member 440, and the pumping member 440 is connected to the water tank through the pumping pipe to guide the water in the water tank to the ice-making member 420. A plurality of water distribution holes 431 can be provided on the water distribution member 430, and the plurality of water distribution holes 431 can be arranged at intervals on the water distribution member 430 to disperse and discharge the water flow, thereby facilitating improving the uniformity of the multiple ice cubes made on the ice-making member 420.

[0084] In one embodiment, the ice-making assembly further includes a pumping member 440, which is disposed below the wet curtain assembly 200, and is connected to the water tank and the water diversion member 430, and is used to guide the water in the water tank toward the water diversion member 430. In this arrangement, the water in the water tank 300 can flow through the ice-making member 420 along the water diversion member 430 under the pumping of the pumping member 440, and the ice-making heat exchanger 410 is connected to the ice-making member 420 by thermal conduction to provide a cold source for the ice-making member 420. After the water flows through the ice-making member 420, it is cooled and flows back to the water tank 300 under the action of gravity, so that the water in the water tank 300 forms ice water; the pumping member 440 can be a water pump. Of course, when the water flows through the ice-making member 420, ice cubes can also be made on the ice-making member 420, and the ice cubes can fall into the water tank to further cool the water in the water tank. This solution improves the efficiency of producing ice water by the refrigeration device 400 by providing a pumping member 440 .

[0085] See also Figure 7 In one embodiment, the water distribution member 430 includes a first water distribution pipe 432 and a second water distribution pipe 433. The water pumping member 440, the first water distribution pipe 432 and the second water distribution pipe 433 are connected in sequence. The second water distribution pipe 433 is annular and arranged corresponding to the base frame 421. The second water distribution pipe 433 is provided with a plurality of water distribution holes 431 along its annular direction. Such arrangement enables water to flow out from the plurality of water distribution holes 431 respectively when passing through the second water distribution pipe 433, so that the water flow discharged from the second water distribution pipe 433 is more dispersed, and the water dispersedly flowing out of the plurality of water distribution holes 431 flows to the ice making part 422 arranged in an annular shape, so that ice cubes can be made in the plurality of ice making grooves 424 of the ice making part 422, so that the ice making efficiency of the ice making part 422 and the uniformity of making a plurality of ice cubes are improved.

[0086] See also Figure 7In one embodiment, the first water distribution pipe 432 includes a first sub-pipe 434 and at least two second sub-pipes 435, and both ends of each of the second sub-pipes 435 are respectively connected to the first sub-pipe 434 and the second water distribution pipe 433, and the connection between the two second sub-pipes 435 and the second water distribution pipe 433 is arranged at intervals.

[0087] It is understandable that the number of the second sub-tubes 435 can be two, three, or more, and the specific number is not limited here. In this embodiment, the number of the second sub-tubes 435 is two, one end of each of the two second sub-tubes 435 is connected to the first sub-tube 434, and the other ends of the two second sub-tubes 435 are arranged at intervals and respectively connected to the second water distribution pipe 433, and the first sub-tube 434 is arranged below the second sub-tube 435, so that the first water distribution pipe 432 is arranged in a Y shape. In this arrangement, the water in the first sub-tube 434 is divided into two streams when passing through the two second sub-tubes 435, and the two streams flow into the second water distribution pipe 433 from different positions, so that the water in the second water distribution pipe 433 can be quickly dispersed and flow through the multiple water distribution holes 431, so as to increase the water outlet speed of the multiple water distribution holes 431, which is conducive to improving the ice making speed and ice making uniformity of the ice making part 422.

[0088] See also Figure 3 and Figure 8 In one embodiment, the ice-making assembly further includes a water diversion box 450, at least part of which is disposed above the ice-making component 420, and the water diversion component 430 is provided with a plurality of water diversion holes 431, and the water diversion box 450 is used to guide the water flowing out of the plurality of water diversion holes 431 to different positions of the ice-making component 420.

[0089] It can be understood that the water diversion box 450 can be completely arranged above the ice-making component 420, and of course, it can also be only partially arranged above the ice-making component 420. The water diversion box 450 guides the water discharged from the multiple water diversion holes 431 to be diverted to different positions of the ice-making component 420 to make the water flow more evenly, thereby making the ice cubes made on the ice-making component 420 more dispersed and uniform, and also helping to improve the ice-making efficiency.

[0090] In one embodiment, a plurality of guide ribs 451 are provided on the wall of the water diversion box 450, and two adjacent guide ribs 451 and the wall of the water diversion box 450 form a guide channel, and the downward projection of each water diversion hole 431 falls into one of the guide channels, and the guide channel is used to guide the water flowing out of the water diversion hole 431 toward the ice making groove 424 of the ice making part 422.

[0091] It is understandable that two adjacent guide ribs 451 are spaced apart on the wall surface of the water diversion box 450 to form a guide channel, and the guide channel can guide water. Multiple water diversion holes 431 are located above the multiple guide channels, and the downward projection of each water diversion hole 431 falls into a guide channel. After the water flows into the water diversion part 430, it flows out from the multiple water diversion holes 431 respectively to form multiple streams of water. After each stream of water falls into a guide channel, it flows along the guide channel. The guide channel guides the water toward the ice-making groove 424 of the ice-making part 422. The ice-making part 422 absorbs the heat of the surrounding water so that ice cubes can be made in each ice-making groove 424. Specifically, the guide channel guides the water to the outside of the notch flowing through the ice-making groove 424. When the ice-making heat exchanger 410 is the cold source and transfers the cold air to the ice-making part 420, ice cubes can be formed in the ice-making groove 424. Each guide channel is arranged corresponding to an ice-making groove 424. In the present embodiment, the notch of each ice-making groove 424 is located below the guide channel. Each guide channel guides water to flow through the notch of each ice-making groove 424 and then fall into the water groove, so that ice cubes can be made in each ice-making groove 424, thereby improving the ice-making efficiency.

[0092] In one embodiment, the diversion channel has a diversion slope 452, and the water diversion hole 431 is arranged above the diversion slope 452. The diversion slope 452 is inclined downwardly toward the notch direction of the ice-making groove 424 of the ice-making part 422. In this way, the diversion slope 452 can divert water and increase the water flow speed, and can also divert water toward the notch direction of the ice-making groove 424, so that the efficiency of ice cube formation in the ice-making groove 424 can be improved. Among them, the diversion slope 452 can be an inclined plane, and of course it can also be an inclined arc surface, which is not specifically limited here. In this embodiment, the inclination direction of the diversion slope 452 is inclined downwardly toward the accommodating space 423 outside the self-made ice piece 420, that is, the diversion slope 452 is inclined toward the accommodating space 423, and the notch of the ice-making groove 424 is toward the accommodating space 423.

[0093] In one embodiment, the water diversion box 450 is arranged in an annular shape, and the water diversion member 430 is arranged in an annular direction on the water diversion box 450. In this way, the multiple water diversion holes 431 on the water diversion member 430 are arranged in sequence along the annular direction of the water diversion box 450, which is conducive to the water flowing out of the multiple water diversion holes 431 on the water diversion member 430 being divided into multiple streams on the water diversion box 450, so as to be arranged correspondingly to the multiple ice-making grooves 424; and the annular water diversion box 450 is arranged correspondingly to the annular base frame 421, so that the water diversion box 450 can be adaptively installed on the base frame 421 of the ice-making member 420, which is conducive to improving ice-making efficiency and installation stability.

[0094] In one embodiment, the water diversion box 450 is provided with a slot, and the water diversion member 430 is provided in the slot. Such a configuration enables the water diversion member 430 to be stably installed on the water diversion box 450, avoiding the need to provide additional fasteners to install and fix the water diversion member 430, thereby improving the utilization rate of the water diversion box 450.

[0095] In one embodiment, the water separation box 450 is provided with an annular mounting groove with an opening facing downward, and at least part of the ice-making heat exchanger 410 is disposed in the annular mounting groove. Such an arrangement enables the ice-making heat exchanger 410 to exchange heat with the water separation box 450, which is beneficial to improving the ice-making speed and ice-removing speed; and the internal space of the water separation box 450 can be fully utilized, thereby improving the space utilization rate of the water separation box 450, which is beneficial to the miniaturization of the refrigeration device 400.

[0096] In one embodiment, the downward projection of the accommodating space 423 falls into the water tank; and / or, the ice-making heat exchanger 410 is disposed on the ice-making element 420 .

[0097] It can be understood that part of the water distribution member 430 is arranged in the accommodating space 423, and the downward projection of the accommodating space 423 falls into the water tank, so that the bottom of the water distribution member 430 can extend toward the water tank, and the upper half of the water distribution member 430 can be arranged in the accommodating space 423. In this way, the internal space of the ice-making member 420 is fully utilized, which is beneficial to shortening the pipeline length of the water distribution member 430, thereby facilitating the miniaturization of the refrigeration device 400.

[0098] See also Figure 3 In one embodiment, the refrigeration device 400 further includes an ice-making bracket 460, the ice-making bracket 460 is arranged on the water tank 300, the ice-making component 420 is arranged on the ice-making bracket 460, and the ice-making heat exchanger 410 is arranged on the ice-making component 420. It can be understood that by providing the ice-making bracket 460, it is convenient to install the ice-making component 420, and the installation method of the ice-making bracket 460 and the water tank 300 includes but is not limited to plug-in, or snap-on connection, or fastener connection, etc., and specifically in this solution, the water tank 300 is provided with a plurality of plug-in holes, and the ice-making bracket 460 is correspondingly provided with a plurality of plug-in columns, which are inserted into the plug-in holes, so that the ice-making bracket 460 can be stably installed on the water tank 300.

[0099] Furthermore, the ice-making component 420 is installed on the ice-making bracket 460 in a manner including but not limited to a snap connection or a fastener connection. In the present embodiment, the base frame 421 of the ice-making component 420 and the ice-making bracket 460 are provided with corresponding assembly holes for fasteners (such as screws or pins, etc.) to pass through. The ice-making component 420 and the ice-making bracket 460 are connected and fixed by fasteners, and the assembly is simple, convenient, stable and reliable.

[0100] In one embodiment, the ice-making part 422 is arranged on the side of the base frame 421 facing downward, and the ice-making heat exchanger 410 is arranged on the side of the base frame 421 facing upward. In this way, the ice-making heat exchanger 410 and the ice-making part 422 are arranged on opposite sides of the base frame 421, and the ice-making heat exchanger 410 and the ice-making part 422 do not interfere with each other, which is conducive to the ice cubes made by the ice-making part 422 to be smoothly detached and fall into the water tank of the water tank 300. The ice-making part 422 is arranged on the side of the base frame 421 facing downward, so that the ice-making part 422 is located at the lower half of the ice-making part 420, thereby reducing the height of the ice-making part 422, so that the ice cubes made by the ice-making part 422 can quickly fall into the water tank 300 when they fall off, and can also reduce the splash and noise of the ice cubes falling into the water tank 300.
