Description

Technical Field

[0001] The present application relates to refrigeration equipment, and in particular, to a refrigerator air duct cover assembly and a refrigerator. Background Art

[0002] A refrigerator is a civilian product that can keep food or other items at a constant low temperature. The refrigerator is equipped with components such as a compressor and a heat exchanger to achieve refrigeration. A refrigerator usually includes a refrigerator and a freezer, which can hold items with different low temperature requirements.

[0003] In order to supply air to the compartments, refrigerators generally have duct modules, and duct covers are set inside the refrigerator to cover the duct modules. Users can directly see the duct covers from inside the refrigerator. For some refrigerators, the refrigerator compartment is relatively long. In order to facilitate installation and transportation by on-site personnel and gear control of injection molded products, the duct cover can be divided into multiple covers. In many cases, the docking structure is a zero-touch zero design. During the refrigeration process, due to the effects of thermal expansion and contraction, flash seams will appear at the docking parts of multiple covers. Flash seams may cause debris in the refrigerator to enter the duct module, and dust in the duct module to enter the refrigerator. Moreover, the flash seams are not beautiful and are prone to user complaints. Utility Model Content

[0004] The present application provides a refrigerator air duct cover assembly and a refrigerator, which can block dust and prevent users from directly seeing the gaps, making the refrigerator more beautiful.

[0005] Specifically, the present application is implemented through the following technical solutions:

[0006] One aspect of the present application provides a refrigerator air duct cover assembly, which is installed in a refrigerator and includes:

[0007] An air duct cover plate, comprising a first air duct cover plate and a second air duct cover plate, wherein the second air duct cover plate is connected to the first air duct cover plate, and the air duct cover plate has a first side facing the refrigerator compartment and a second side facing the refrigerator air duct;

[0008] A blocking member covers the junction of the first air duct cover plate and the second air duct cover plate and is located on the first side.

[0009] Optionally, the side surface of the blocking member facing away from the air duct cover plate is an arc-shaped surface.

[0010] Optionally, along the height direction of the refrigerator, the first air duct cover plate and the second air duct cover plate are distributed up and down, and along the direction of the second side pointing to the first side, the size of the top of the baffle is larger than the size of the bottom of the baffle.

[0027] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0028] Please refer to Figures 1 to 3 In the existing refrigerator, when viewed from the refrigerator compartment 10, the joint 30 of the multiple air duct cover plates is a zero plus zero design, that is, the joint 30 of the multiple air duct cover plates has no connection structure, so there will be a gap at the joint 30. In addition, since the temperature inside the refrigerator compartment is relatively low, thermal expansion and contraction will cause flash cracks to appear at the joint 30 of the air duct cover plates. For example, the multiple air duct cover plates include an upper cover plate 21 and a lower cover plate 22. At low temperatures, the upper cover plate 21 and the lower cover plate 22 will shrink. Please combine Figure 2 and 3 The upper cover plate 21 shrinks upward (in the direction of the upward arrow in the figure), and the lower cover plate 22 shrinks downward (in the direction of the downward arrow in the figure), thereby enlarging the gap at the joint 30, thus forming a flash gap. When users put items in or take items out of the refrigerator compartment, or check the refrigerator, they may find this flash gap, questioning the quality of the refrigerator, which will have a great impact on the sales of the refrigerator and the user experience.

[0029] The terms "first", "second" and similar terms used in this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Figure 4 and Figure 5The present application provides a refrigerator air duct cover assembly, which is installed in a refrigerator. The refrigerator air duct cover assembly includes an air duct cover 100 and a blocking member 200. The air duct cover 100 includes a first air duct cover 110 and a second air duct cover 120. The second air duct cover 120 is connected to the first air duct cover 110. The connection here means that there is no connection structure, which is a connection in position. The air duct cover 100 has a first side 100a for facing the refrigerator compartment and a second side 100b for facing the refrigerator air duct. That is, the air duct cover 100 blocks the refrigerator air duct, so that the user can see the air duct cover 100 instead of the refrigerator air duct when looking from the refrigerator compartment. The orientation relationship of the refrigerator in normal use is used to illustrate that the first air duct cover 110 and the second air duct cover 120 can be distributed up and down, or left and right, etc., and the distribution relationship of the first air duct cover 110 and the second air duct cover 120 inside the refrigerator is not limited here. The air duct cover plate 100 may include a plurality of air duct cover plates, and the first air duct cover plate 110 and the second air duct cover plate 120 may be just two adjacent cover plates. The blocking member 200 covers the junction of the first air duct cover plate 110 and the second air duct cover plate 120 and is located at the first side.

[0030] Due to the low temperature inside the refrigerator compartment, the first air duct cover plate 110 and the second air duct cover plate 120 will shrink, and the junction of the first air duct cover plate 110 and the second air duct cover plate 120 will expand, and a flash gap will appear. The blocking member 200 of the present application covers the junction and is located on the first side 100a of the air duct cover plate 100 facing the refrigerator compartment. On the one hand, the flash gap can be blocked, that is, the passage between the inside of the refrigerator and the air duct module can be blocked, and the debris in the refrigerator can be reduced from entering the air duct module through the flash gap, and the dust in the air duct module can be reduced from entering the refrigerator through the flash gap. Further, when the user looks from the refrigerator compartment to the junction of the first air duct cover plate 110 and the second air duct cover plate 120, the line of sight will be blocked by the blocking member 200, and the flash gap will not be seen. Preventing the user from directly seeing the flash gap can not only meet the appearance requirements, be more beautiful, but also dispel the user's concerns. The blocking member 200 can be fixed on the first air duct cover plate 110, or the second air duct cover plate 120, or can be fixed on the inner liner of the refrigerator compartment. The refrigerator compartment can be a refrigerator compartment or a freezer compartment. Specifically, the blocking member 200 covers the flash gap, which means that the length and width of the blocking member 200 are greater than or equal to the flash gap.

[0031] In one embodiment, in combination Figure 4 and Figure 6The side of the baffle 200 facing away from the air duct cover 100 is a curved surface. When the user is cleaning the refrigerator compartment or changing the shelf, the user may touch the baffle 200. The side of the baffle 200 facing away from the air duct cover 100 is a curved surface, that is, the side facing the user is a curved surface. Compared with a flat surface, the curved surface feels smoother and can also prevent the straight part of the plane from cutting the user. On the other hand, visually, the curved surface can effectively scatter the light instead of focusing the light on one point, which can reduce reflection and glare, making the user feel more comfortable.

[0032] Hereinafter, unless otherwise specified, the words "front", "rear", "lower" and / or "upper", "top", "bottom" and the like are only for the convenience of explanation and are not limited to a position or a spatial orientation. In one embodiment, along the height direction of the refrigerator, that is, the height direction of the refrigerator when the refrigerator is placed on the ground in a normal use state. The first air duct cover plate 110 and the second air duct cover plate 120 are distributed up and down, and the first air duct cover plate 110 is located above the second air duct cover plate 120. Along the direction from the second side 100b to the first side 100a, the size of the top of the blocking member 200 is greater than the size of the bottom of the blocking member 200. The top and bottom mentioned here are the top and bottom along the height direction of the refrigerator. The size here refers to the thickness of the blocking member 200 along the direction from the second side 100b to the first side 100a. The size of the top of the blocking member 200 is greater than the size of the bottom of the blocking member 200, and the side of the blocking member 200 facing the refrigerator compartment is an arc surface, that is, the size of the blocking member 200 gradually changes from wide to narrow from top to bottom. During the process of opening and closing the refrigerator, condensed water will be generated inside the refrigerator due to the alternation of hot and cold. The size of the stopper 200 is gradually reduced, which can guide the condensed water condensed on the stopper 200 to fall along the shape of the stopper 200 instead of staying on the stopper 200 and solidifying.

[0033] In one embodiment, in combination Figure 6 . The top surface of the blocking member 200 is tilted relative to the direction in which the second side 100b points to the first side 100a. The second side 100b points to the horizontal direction of the first side 100a, and the top surface of the blocking member 200 is tilted. The above embodiment mentioned that the top size of the blocking member 200 is large, so condensed water will remain on the top surface of the blocking member 200 and frost, which is difficult to clean. In this embodiment, the top surface is tilted, and the condensed water will be discharged from the top surface along the tilted surface, reducing the residual condensed water.

[0034] In one embodiment, in combination Figure 7 and Figure 8. The baffle 200 and the first air duct cover plate 110 are an integrated structure. In the height direction of the refrigerator, the first air duct cover plate 110 is located above the second air duct cover plate 120. The baffle 200 is integrated with the first air duct cover plate 110, and the condensed water of the first air duct cover plate 110 can be discharged along the baffle 200, reducing the condensed water remaining on the first air duct cover plate 110. In addition, compared with the integrated design of the baffle 200 and the second air duct cover plate 120, this embodiment can prevent condensed water from flowing into the air duct part of the refrigerator through the flash gap. Assuming that the baffle 200 and the second air duct cover plate 120 are an integrated structure, the baffle 200 covers the flash gap from bottom to top. The condensed water flowing down from the first air duct cover plate 110 may flow between the baffle 200 and the flash gap, and then flow into the air duct part of the refrigerator from the flash gap. In this embodiment, the baffle 200 is integrated with the first air duct cover 110, and the baffle 200 covers the flash gap from top to bottom. Condensed water flows down along the baffle 200 and does not enter the flash gap.

[0035] In one embodiment, in combination Figure 6 The first air duct cover plate 110 points to the direction of the second air duct cover plate 120, and the size of the blocking member 200 ( Figure 6 In the figure, y) is 2.5mm-5mm. That is, the size of the flash gap at the junction of the first air duct cover plate 110 and the second air duct cover plate 120 covered by the baffle 200. Due to thermal expansion and contraction, the first air duct cover plate 110 and the second air duct cover plate 120 shrink, and the flash gap at the junction becomes larger. The shrinkage of the first air duct cover plate 110 and the second air duct cover plate 120 is related to the materials used. For example, PP (polypropylene), PS (polystyrene), PET (polyethylene terephthalate), etc. can be used respectively. Different materials have different shrinkage amounts, and the size of the flash gap at the junction of the first air duct cover plate 110 and the second air duct cover plate 120 is also different. The size required for the baffle 200 to cover the flash gap is also different. In this embodiment, different sizes of the baffle 200 can be designed according to the material used for the cover plate and the specific working conditions of the refrigerator. Specifically, the size of the baffle 200 can be 2.5mm, 2.8mm, 3mm, 3.5mm, 4mm, etc.

[0036] In one embodiment, the air duct cover is a polypropylene cover (PP), and the size of the blocking member 200 is greater than or equal to 4 mm along the direction from the first air duct cover 110 to the second air duct cover 120, and can be specifically 4 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5 mm, etc. The shrinkage of the polypropylene cover (PP) is relatively large, and the air duct cover is made of polypropylene material. During the refrigeration process, the flash gap between the first air duct cover 110 and the second air duct cover 120 will be relatively large. According to actual tests, the size of the blocking member 200 is preferably designed to be 4 mm, which can just cover the flash gap. Polypropylene material has competitive advantages over polystyrene material from the perspective of cost and toughness, and has been used in many refrigerator products in recent years.

[0037] In another embodiment, the air duct cover is a polystyrene cover (PS), and along the direction from the first air duct cover 110 to the second air duct cover 120, the size of the stopper 200 is greater than or equal to 2.5 mm, and specifically can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 3 mm, etc. The shrinkage of polystyrene is smaller than that of polypropylene, and the gap between the first air duct cover 110 and the second air duct cover 120 due to shrinkage is also smaller. According to actual tests, it is preferred that the size of the stopper 200 is set to 2.5 mm so that the stopper can cover the gap between the polystyrene cover plates.

[0038] In one embodiment, the distance between the blocking member 200 and the first air duct cover plate 110 and the second air duct cover plate 120 is ( Figure 6 x) is 1mm-2mm. Specifically, it can be 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm. A gap is left between the blocking member 200 and the first air duct cover plate 110 and the second air duct cover plate 120, so that the blocking member 200 does not affect the assembly of the first air duct cover plate 110 and the second air duct cover plate 120. However, the gap should not be too large, which occupies the space of the refrigerator compartment and is not beautiful. Therefore, this embodiment can facilitate the assembly between the first air duct cover plate 110 and the second air duct cover plate 120, and maintain the beauty of the refrigerator compartment.

[0039] The present application also provides a refrigerator, which may be a side-by-side refrigerator, a T-shaped refrigerator, a three-door refrigerator, etc. The refrigerator includes the refrigerator air duct cover assembly described in any of the above embodiments.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
