Description

Technical Field

[0001] This application relates to the field of refrigeration equipment, and in particular to a cover assembly, a humidification box, and a refrigeration device. Background Technology

[0002] With the rapid development of the global home appliance industry, refrigerators have become an indispensable household appliance for people. They can be used to extend the shelf life of food. For some foods that need to be kept moist, the longer the moisture is present, the higher the freshness of the food. Therefore, using a moisture-retaining box to keep these foods moist has become a mainstream trend.

[0003] It is known that different foods have different requirements for storage humidity. Therefore, adjusting the internal humidity of the humidifier according to the type of food can more effectively extend the shelf life of the food. However, existing humidifiers usually cannot adjust the internal humidity, and they usually do not display the internal humidity information, making it impossible for users to adjust the humidity level of the humidifier according to the preservation needs of the food.

[0053] See also Figures 1 to 5This application provides a cover plate assembly 100, including a cover plate 20, a slider 40, and a humidity display assembly 10. The cover plate 20 is provided with a ventilation window assembly. The slider 40 is disposed on one side of the cover plate 20 and is slidably connected to the cover plate 20. During the sliding process, the slider 40 can block the ventilation window assembly to different degrees. When the ventilation area of ​​the ventilation window assembly changes, the humidity information displayed by the humidity display assembly 10 changes.

[0054] For example, the humidity information is displayed in the form of text, symbols, or patterns.

[0055] The cover assembly 100 provided in this application embodiment has a ventilated window assembly on the cover 20 and a slider 40 on one side of the cover 20, which is slidably connected to the cover 20. During the sliding process, the slider 40 can block the ventilated window assembly to different degrees, thereby adjusting the ventilation area of ​​the ventilated window assembly and thus adjusting the humidity performance of the humidifying box including the cover assembly 100. At this time, the user can adjust the humidity performance of the humidifying box according to the properties of the food, so as to avoid the food in the humidifying box from spoiling or losing moisture, thereby extending the shelf life of the food. Since the cover assembly 100 includes a humidity display component 10, and the humidity information displayed by the humidity display component 10 changes with the ventilation area of ​​the ventilated window assembly, and the ventilation area of ​​the ventilated window assembly is directly related to the humidity level of the humidifying box, the user can adjust the ventilation area of ​​the ventilated window assembly according to the preservation requirements of the food, thereby adjusting the humidity level of the humidifying box.

[0056] See also Figure 5 The humidity display component 10 includes a display block 11, a first gear 12, and a first rotating shaft 13. The display block 11 and the first gear 12 are connected through the first rotating shaft 13, and the first rotating shaft 13 is rotatably connected to the cover plate 20. The slider 40 is provided with a first rack 47, which meshes with the first gear 12. Multiple humidity information is provided on the side of the display block 11 along its circumference, and a viewing window 24 is provided on the cover plate 20 corresponding to the area of ​​the display block 11.

[0057] In the embodiments of this application, "multiple" refers to two or more, such as three, four, five, six, etc.

[0058] See also Figure 6 and Figure 7 For example, the humidity information includes humidity levels such as high humidity, medium humidity, and low humidity.

[0059] See also Figure 3 and Figure 4For example, the perspective window 24 is a hollow area.

[0060] It is understandable that when the slider 40 moves left and right, since the first rack 47 on the slider 40 meshes with the first gear 12, the slider 40 will drive the gear to rotate, thereby driving the display block 11 to rotate together. At this time, the words "low humidity", "medium humidity" and "high humidity" on the side of the display block 11 will rotate continuously, thereby showing the humidity level inside the humidification box when the slider 40 is in different positions.

[0061] See also Figure 9 and Figure 10 The cover plate 20 includes a cover plate body 21 and a support plate 26 connected together. The support plate 26 and the slider 40 are disposed on the same side of the cover plate body 21. The support plate 26 is connected to the cover plate body 21. The support plate 26 is provided with a first through hole 261. The first rotating shaft 13 is engaged in the first through hole 261 and can rotate in the first through hole 261.

[0062] See also Figure 10 For example, the number of support plates 26 can be multiple, and the multiple support plates 26 are parallel to each other.

[0063] See also Figures 8 to 10 The slider 40 includes a slider body 61 and a protective cover 62 connected to the slider body 61. The protective cover 62 has an opening on the side facing the cover body 21. During the sliding of the slider, the protective cover 62 always covers the periphery of the humidity display component 10 and the support plate 26.

[0064] See also Figure 8 The protective cover 62 includes a first top plate and a fifth side plate connected together. The side of the fifth side plate opposite to the first top plate is connected to the slider body 61. The first top plate is provided with the first rack 47 on the side facing the cover plate body 21.

[0065] For example, the protective cover 62 is in the shape of a cuboid, a cube, or a cylinder.

[0066] It is understandable that by setting a protective cover 62 around the humidity display component 10 and the support plate 26, not only can the protective cover 62 be used to shield and protect the humidity display component 10 and the support plate 26, but also, since the protective cover 62 is protruding relative to the slider body 61, when the knob 52 is damaged or cannot work properly, the protective cover 62 can be moved manually to drive the slider 40 to move as a whole, thereby realizing the adjustment of the ventilation window area of ​​the cover assembly 100.

[0067] See also Figure 1 and Figure 2 At the same time, combined Figure 3 and Figure 4 The cover plate assembly also includes a transparent element 25, which covers the viewing window 24, and the transparent element 25 is connected to the cover plate body 21.

[0068] It is understandable that by setting the position of the transparent part 25 in the perspective window 24, the transparent part 25 can block the perspective window 24, thereby sealing the humidification box using the cover assembly, so that the humidification box can only exchange gas through the ventilation window assembly; and, since the transparent part 25 has light transmission properties, the humidity information on the display block 11 will not be blocked, and the display effect will not be affected.

[0069] For example, the transparent element 25 has a transmittance of visible light greater than or equal to 80%, such as 80%, 82%, 85%, 88%, 90%, 92%, 95%, 98%, 100%, etc.

[0070] See also Figure 9 and Figure 10 The cover plate also includes a limiting structure 90, which is disposed on the same side of the cover plate body as the slider. The limiting structure 90 includes a limiting plate 91 connected to the cover plate body and a third buckle 92 connected to the limiting plate 91. The edge area of ​​the transparent part 25 is engaged between the third buckle 92 and the cover plate body.

[0071] See also Figure 9 and Figure 10 The number of the limiting structures 90 is multiple, and the multiple limiting structures 90 are arranged around the perspective window 24.

[0072] See also Figure 11 and Figure 12 The cover plate assembly 100 further includes a drive assembly, which includes a second gear 51, a knob 52, and a second rotating shaft. The second gear 51 and the knob 52 are connected through the second rotating shaft. The edge of the slider 40 is provided with a second rack 45. The second gear 51 and the slider 40 are disposed on the same side of the cover plate 20, and the second gear 51 meshes with the second rack 45. The knob 52 is disposed on the side of the cover plate 20 opposite to the second gear 51, and the knob 52 is connected to the second gear 51. The cover plate is provided with a second through hole, and at least a portion of the second rotating shaft is located in the second through hole.

[0073] It is understood that the second rack 45 includes a plurality of teeth arranged sequentially at intervals in a straight line direction, and the edge of the second gear 51 is provided with a plurality of teeth arranged sequentially at intervals in a circumferential direction.

[0074] It is understandable that by setting the second gear 51 and the knob 52 on both sides of the cover plate 20 respectively, the following technical effects can be achieved: When the cover plate assembly 100 is set at the opening of the box body and together with the box body to form a moisturizing box, the side where the knob 52 is located can be set as the outer side of the moisturizing box. At this time, the user can rotate the knob 52 to make the second gear 51 rotate. When the second gear 51 rotates, the slider 40 moves left and right through the meshing of the second gear 51 and the second rack 45. When the slider 40 moves, the slider 40 can block the vent window assembly to different degrees, thereby adjusting the ventilation area of ​​the vent window assembly, and thus adjusting the moisturizing performance of the moisturizing box containing the cover plate assembly 100. Because the meshing transmission effect of the second gear 51 and the second rack 45 is good, the user can rotate the knob 52 effortlessly and with a good feel.

[0075] Please see Figure 11 and Figure 12 The ventilation window assembly includes a first ventilation window 211 and a second ventilation window 212 arranged at intervals, and the slider 40 is provided with a first hollow part 41 and a second hollow part 42 arranged at intervals.

[0076] When the slider 40 moves in the direction from the first ventilation window 211 to the second ventilation window 212 or in the direction from the second ventilation window 212 to the first ventilation window 211, the overlapping area of ​​the first ventilation window 211 and the first hollow part 41 changes, and the overlapping area of ​​the second ventilation window 212 and the second hollow part 42 changes.

[0077] Please see Figure 12 For example, the first hollow portion 41 and the second hollow portion 42 are respectively disposed on both sides of the protective cover 62.

[0078] Please see Figure 1 and Figure 3 The first ventilation window 211 includes a plurality of first ventilation holes spaced apart, and the second ventilation window 212 includes a plurality of second ventilation holes spaced apart.

[0079] Please see Figure 3 and Figure 4 For example, the first ventilation window 211 and the second ventilation window 212 are respectively disposed on both sides of the viewing window 24.

[0080] Please see Figure 14When the first ventilation window 211 is fully exposed in the first hollow portion 41 and the second ventilation window 212 is fully exposed in the second hollow portion 42, it means that the ventilation area of ​​the cover assembly 100 is the sum of 100% of the ventilation area of ​​the first ventilation window 211 and 100% of the ventilation area of ​​the first ventilation window 211. At this time, the box (drawer) covered by the cover assembly 100 maintains the strongest gas flow with the outside, the moisturizing performance of the moisturizing box (moisturizing drawer) is the worst, and the humidity inside the moisturizing box (moisturizing drawer) is low.

[0081] See also Figure 15 When the first ventilation window 211 and the second hollow part 42 are completely covered by the slider body 61, the overlap area between the first ventilation window 211 and the first hollow part 41 is zero, and the overlap area between the second ventilation window 212 and the second hollow part 42 is zero. At this time, the ventilation area of ​​the cover assembly 100 is zero. At this time, the gas flow between the box (drawer) covered by the cover assembly 100 and the outside world stops, and the moisturizing performance of the moisturizing box (moisturizing drawer) is optimal, and the humidity inside the moisturizing box (moisturizing drawer) is high.

[0082] See also Figure 13 When half of the first ventilation window 211 is exposed in the first hollow portion 41 and half of the second ventilation window 212 is exposed in the second hollow portion 42, it means that the ventilation area of ​​the cover assembly 100 is the sum of 50% of the ventilation area of ​​the first ventilation window 211 and 50% of the ventilation area of ​​the first ventilation window 211. At this time, the box (drawer) covered by the cover assembly 100 maintains a moderate air flow with the outside, the moisturizing performance of the moisturizing box (moisturizing drawer) is moderate, and the humidity inside the moisturizing box (moisturizing drawer) is moderate.

[0083] See also Figure 11 as well as Figures 13 to 15 The cover plate 20 includes a cover plate body 21 and a baffle structure connected together. The baffle structure and the slider 40 are disposed on the same side of the cover plate body 21. The baffle structure is connected to the cover plate body 21. The baffle structure includes a first baffle 31 and a second baffle 32 that are spaced apart and parallel to each other. The vent window assembly is provided on the cover plate body 21.

[0084] See also Figure 12The slider 40 includes a slider body 61 and a side plate structure connected together. The side plate structure is disposed on the side of the slider body 61 away from the cover plate body 21. The edge of the slider body 61 is provided with the second toothed rack 45. The side plate structure includes a first side plate 71 and a second side plate 72 that are spaced apart and parallel to each other. The slider body 61 is provided with the first hollow part 41 and the second hollow part 42.

[0085] Please combine Figure 11 , Figure 12 as well as Figures 13 to 15 The side of the first side plate 71 opposite to the second side plate 72 abuts against the first baffle 31, and the side of the second side plate 72 opposite to the first side plate 71 abuts against the second baffle 32.

[0086] It is understandable that by setting the first side plate 71 to abut against the first baffle 31 and the second side plate 72 to abut against the second baffle 32, it is equivalent to using the first baffle 31 and the second baffle 32 to define the channel that allows the slider 40 to move, so that the slider 40 moves along the defined route.

[0087] For example, the length of the first side plate 71 is equal to the length of the second side plate 72, and the length of the first baffle 31 is equal to the length of the second baffle 32.

[0088] Please see Figure 12 For example, the first side plate 71 and the second side plate 72 are respectively disposed on both sides of the protective cover 62.

[0089] Please combine Figure 11 as well as Figures 13 to 15 The first baffle 31 includes a first plate body and a first buckle 81 connected together. The first buckle 81 is disposed on the side of the first plate body facing the second side plate 72, and the side of the first side plate 71 facing away from the slider body 61 abuts against the first buckle 81.

[0090] The second baffle 32 includes a connected second plate body and a second buckle 82. The second buckle 82 is disposed on the side of the second plate body facing the first side plate 71, and the side of the second side plate 72 away from the slider body 61 abuts against the second buckle 82.

[0091] It is understandable that by setting the first buckle 81 and the second buckle 82 to abut against the first side plate 71 and the second side plate 72 respectively, the slider 40 can be limited by the first buckle 81, the second buckle 82 and the cover plate body 21, thereby preventing the slider 40 from separating from the cover plate 20.

[0092] Please see Figure 11The length of the first baffle 31 is greater than the length of the first side plate 71, and the length of the second baffle 32 is greater than the length of the second side plate 72. The baffle structure also includes a third baffle 33 and a fourth baffle 34 that are spaced apart and parallel to each other. The two ends of the third baffle 33 are respectively connected to one end of the first baffle 31 and one end of the second baffle 32, and the two ends of the fourth baffle 34 are respectively connected to the other end of the first baffle 31 and the other end of the second baffle 32.

[0093] It is understandable that by setting the length of the first side plate 71 to be greater than the length of the first baffle 31, the length of the second side plate 72 to be greater than the length of the second baffle 32, and the baffle structure including the third baffle 33 and the fourth baffle 34, the third baffle 33 and the fourth baffle 34 can act as stop members. That is to say, when the slider 40 moves left or right to the third baffle 33 or the fourth baffle 34, it will stop. This can limit the two endpoints of the slider 40 in the left and right movement direction and prevent the slider 40 from moving too far and separating from the baffle structure.

[0094] Please see Figure 12 The side plate structure includes a third side plate 73 and a fourth side plate 74 that are spaced apart and parallel to each other. The two ends of the third side plate 73 are respectively connected to one end of the first side plate 71 and one end of the second side plate 72, and the two ends of the fourth side plate 74 are respectively connected to the other end of the first side plate 71 and the other end of the second side plate 72.
