[0031] The embodiments of this application are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0032] The following is combined with Figures 1-7 Describes an ice-making apparatus 10 according to an embodiment of this application.

[0033] The ice-making device 10 of this application embodiment includes an ice-making shell 1, an air guide 3, and a filter module 4. The ice-making shell 1 has an ice-making cavity 12, the air guide 3 is connected to the ice-making shell 1, the air guide 3 has an air inlet channel 33 communicating with the ice-making cavity 12, and the filter module 4 is connected to the air guide 3 for filtering the cold air passing through the air inlet channel 33.

[0034] According to the ice-making apparatus 10 of this application embodiment, the ice-making shell 1 and the air guide 3 are both located in the freezer chamber 5 of the refrigeration equipment. The cold air from the refrigeration equipment enters the ice-making cavity 12 through the air inlet channel 33 to exchange heat with the water in the ice-making cavity 12, thus completing the ice-making operation. A filter module 4 is connected to the air guide 3. When the cold air passes through the air inlet channel 33, it passes through the filter module 4. The filter module 4 can filter out bacteria, viruses, and odors carried by the cold air, thereby effectively ensuring the forming quality and food safety of the ice blocks in the ice-making cavity 12.

[0035] It should be noted that the ice-making device 10 in this embodiment includes a water storage component, an ice-making component, and an ice storage component, all of which are located in the freezer chamber 5 of the refrigeration equipment. The ice-making component includes the aforementioned ice-making shell 1, air guide 3, and filter module 4. In addition, the ice-making cavity 12 is provided with an ice grid 2 for storing water, and the air outlet direction of the air inlet channel 33 is towards the ice grid 2.

[0036] In some embodiments, the air guide 3 is detachably connected to the ice-making shell 1.

[0037] At this time, when the filter module 4 needs cleaning or replacement due to prolonged use, the air guide 3 can be detached from the ice maker shell 1 to facilitate cleaning or replacement of the filter module 4. Simultaneously, this design effectively reduces the design and manufacturing difficulty of the ice maker shell 1, making it simple and low-cost to manufacture. Furthermore, for refrigerators of different models and sizes, the ice maker shell 1 can be connected to air guide 3 of different sizes, ensuring that after the ice maker 10 is installed in the freezer compartment 5, the air guide 3 always covers the air outlet 61 of the freezer air duct 6, without requiring changes to the size of the ice maker shell 1, further reducing the cost of the ice maker 10.

[0038] For example, such as Figure 4 As shown, the ice-making shell 1 includes a bracket 11 located at the top, and the air guide 3 is snapped into the bracket 11 or connected to it by a threaded part.

[0039] In some embodiments, the filter module 4 is detachably connected to the air guide 3.

[0040] This further facilitates the cleaning and replacement of filter module 4, and when replacing filter module 4, it is not necessary to replace air guide component 3 at the same time, effectively reducing the replacement cost of filter module 4.

[0041] In some embodiments, the filter module 4 and the air guide 3 are inserted into each other along the extension direction of the air inlet channel 33. One of the filter module 4 and the air guide 3 is provided with a locking hole 311, the axial direction of which intersects the extension direction of the air inlet channel 33, and the other of the filter module 4 and the air guide 3 is provided with a locking protrusion 44, which is disposed in the locking hole 311.

[0042] The filter module 4 and the air guide 3 are inserted and connected to each other, so that the two are relatively fixed in all directions except the extension direction of the air inlet channel 33. After the filter module 4 is inserted into the air guide 3 along the extension direction of the air inlet channel 33, the locking protrusion 44 is locked in the locking hole 311, so that the filter module 4 and the air guide 3 are relatively fixed in the extension direction of the air inlet channel 33. Thus, the filter module 4 and the air guide 3 are fixedly connected, and the two are easy to assemble and disassemble and are reliable.

[0043] For example, such as Figures 4-6As shown, the axial direction of the locator 311 is orthogonal to the extension direction of the air inlet channel 33. The locator 311 is provided on the air guide 3 and is a strip-shaped hole along the extension direction perpendicular to the air inlet channel 33.

[0044] In some embodiments, the filter module 4 includes a frame 41, a filter element 42, and a pressure plate 43. The frame 41 is inserted into the air inlet channel 33, the filter element 42 is connected to the frame 41, the pressure plate 43 is connected to the frame 41, and the pressure plate 43 is provided with one of a locking protrusion 44 and a locking hole 311. The inner wall surface of the air guide 3 is provided with the other of a locking protrusion 44 and a locking hole 311.

[0045] By setting one of the protrusion 44 and the hole 311 on the pressure plate 43, the pressure plate 43 can be bent and deformed relative to the frame 41 to avoid the protrusion 44 interfering with the continued insertion of the frame 41 into the air inlet channel 33. After the frame 41 is inserted into place, the pressure plate 43 can elastically rebound so that the protrusion 44 can be inserted into the hole 311. The connection between the filter module 4 and the air guide 3 is more convenient and reliable.

[0046] For example, such as Figure 3 and Figure 4 As shown, the outer contour of the cross-section of the frame 41 matches the outer contour of the cross-section of the air inlet channel 33. When the frame 41 is inserted into place, the outer peripheral surface of the frame 41 is in close contact with the outer wall surface of the air inlet channel 33. The frame 41 forms a mounting hole, and the filter element 42 is connected to the frame 41 and seals the mounting hole. At the same time, when the latch 44 is inserted into the latch hole 311, the pressure plate 43 and the inner wall surface of the air inlet channel 33 are in close contact to reduce the interference of the pressure plate 43 with the airflow of cold air into the ice-making chamber 12, thus ensuring the ice-making efficiency of the ice-making device 10.

[0047] It should be noted that the filter element 42 can be detachably connected to the frame 41 so that only the filter element 42 can be replaced, thereby reducing the replacement cost of the filter module 4.

[0048] In some embodiments, there are at least two protrusions 44 disposed on the pressure plate 43, and at least two holes 311 disposed on the air guide 3.

[0049] The setting of at least two protrusions 44 ensures that at least two fixing points are formed between the pressure plate 43 and the air guide 3. Under the interaction of at least two fixing points, the frame 41 is effectively prevented from shaking relative to the air guide 3 under the blowing of cold air, which would generate noise or even affect the reliability of installation.

[0050] For example, such as Figures 5-7 As shown, there are two pressure plates 43 arranged at intervals along the vertical direction. Each pressure plate 43 is provided with two locking holes 311, which are arranged at intervals along the left and right direction of the refrigeration equipment.

[0051] In some embodiments, the air guide 3 includes a first wall panel 31 and a second wall panel 32 that are opposite each other in the vertical direction, and the wall surfaces of the first wall panel 31 and the second wall panel 32 that are opposite each other are provided with locking holes 311. There are two pressure plates 43 arranged at intervals in the vertical direction, and the wall surfaces of the two pressure plates 43 that are opposite each other are provided with locking protrusions 44.

[0052] By setting the locking holes 311 instead of the locking protrusions 44 on the opposing surfaces of the first wall panel 31 and the second wall panel 32, the manufacturing difficulty and cost of the air guide component 3 are effectively reduced. By setting two pressure plates 43, with the locking protrusions 44 on the two pressure plates 43 respectively inserted into the locking holes 311 of the first wall panel 31 and the second wall panel 32, the connection strength between the filter module 4 and the air guide component 3 is further improved. The filter module 4 is less likely to accidentally detach from the air guide component 3, and its reliability in disinfecting and deodorizing cold air is higher.

[0053] For example, such as Figures 4-7 As shown, each pressure plate 43 is provided with two latching protrusions 44. The two pressure plates 43 are located on the same side of the frame 41. After the latching protrusions 44 are engaged in the corresponding latching holes 311, the opposing wall surfaces of the two pressure plates 43 respectively come into contact with the opposing wall surfaces of the first wall plate 31 and the second wall plate 32.

[0054] In some embodiments, the air inlet channel 33 has an air inlet and an air outlet, and the pressure plate 43 is disposed on the side of the frame 41 facing the air inlet.

[0055] Therefore, when the ice-making device 10 is removed from the freezer compartment 5 of the refrigeration equipment, the two pressure plates 43 are exposed through the air inlet of the air inlet channel 33, which makes it easy to directly move the two pressure plates 43 to make the locking protrusion 44 disengage from the locking hole 311, thereby realizing the removal of the filter module 4 and making the cleaning and replacement of the filter module 4 convenient.

[0056] For example, such as Figure 4 As shown, the ends of the two pressure plates 43 that are away from the frame 41 are exposed outside the air inlet channel 33, which further facilitates the control of the two pressure plates 43 to bend relative to the frame 41 to remove the filter module 4.

[0057] In some embodiments, the inner wall of the air inlet channel 33 is provided with a positioning protrusion 34, and the side of the frame 41 facing the air inlet is provided with a positioning groove 411, and the positioning protrusion 34 is fitted into the positioning groove 411.

[0058] As the frame 41 is inserted from the air inlet into the air inlet channel 33, the frame 41 is inserted into place when the positioning protrusion 34 engages with the positioning groove 411. Combined with the engagement of the locking protrusion 44 and the locking hole 311, the connection reliability between the filter module 4 and the air guide 3 is further improved, effectively avoiding the failure of the connection between the filter module 4 and the air guide 3, which would affect the reliability of its antibacterial disinfection and deodorization of cold air.

[0059] For example, such as Figure 6 and Figure 7 As shown, the positioning protrusion 34 is disposed on the inner wall surface of the first wall panel 31 and adjacent to the air outlet of the air inlet channel 33.

[0060] In some embodiments, the filter element 42 includes at least one of filter cotton, activated carbon, metal mesh, and photocatalyst.

[0061] The filter cotton and metal mesh can effectively filter out small particulate impurities carried by the cold air, while activated carbon and photocatalyst can effectively achieve antibacterial disinfection and deodorization of the cold air. The flexible combination of the above four can effectively ensure the purity of the cold air entering the ice-making chamber 12, and effectively ensure the quality of ice cube forming and food safety.

[0062] For example, filter element 42 includes photocatalyst and / or filter cotton fixed in mounting holes of frame 41.

[0063] like Figure 1 and Figure 2 As shown, the refrigeration device according to the embodiment of this application includes a body 20 and an ice-making device 10. The body 20 has a freezer chamber 5 and a freezer air duct 6. A part of the freezer air duct 6 is located in the freezer chamber 5 and is provided with an air outlet 61. The ice-making device 10 is the ice-making device 10 as described in any of the above embodiments, and the ice-making device 10 is located in the freezer chamber 5.

[0064] The technical advantages of the refrigeration equipment according to the embodiments of this application are the same as the technical advantages of the ice-making device 10 in the above embodiments, and will not be repeated here.

[0065] It should be noted that the refrigeration equipment also includes a door 30, which is connected to the main body 20 and used to seal the freezer compartment 4. The refrigeration equipment may be a refrigerator, which also has at least one of a refrigerator compartment and a crisper compartment.

[0066] In some embodiments, the portion of the refrigeration duct 6 located within the freezer compartment 5 is disposed within the air inlet duct 33. That is, the air inlet duct 33 encloses the portion of the cold air duct that has the air outlet 61.

[0067] In other words, the cold air in the freezer duct 6 enters the ice-making chamber 12 directly through the air inlet channel 33, instead of entering the freezer chamber 5 first and then the ice-making chamber 12. This effectively prevents the cold air from bringing bacteria, viruses and odors from the freezer chamber 5 into the air inlet channel 33, thus reducing the service life of the filter module 4. The filter module 4 has a longer cleaning and replacement cycle and lower cost.
