Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a refrigerator. Background Art

[0002] The refrigerator includes a box body and a door body, and a storage room is formed in the box body to store items. A box opening connected to the storage room is formed at the front end of the box body, and the user can place items in the storage room through the box opening of the box body. The door body is used to open and close the box opening. The refrigerator may also include an outer shell and an inner tank arranged in the outer shell. In order to facilitate the entry of cold air into the storage room, an air duct assembly may be arranged in the inner tank, which can enable air to reflux and exchange heat with the evaporator. The air after heat exchange with the evaporator can be guided into the storage room by the air duct assembly.

[0003] The air duct assembly can have an air duct cover. The original air duct cover is generally injection molded. The structure connected to the box body can be injection molded on the injection molded air duct cover, which is convenient for connecting the injection molded cover and the box body. The air duct cover can also be formed by vacuum forming. Vacuum forming air duct cover is simple to form and has obvious price advantages. It is gradually used in refrigeration equipment such as refrigerators.

[0004] However, due to the process characteristics of the blister itself, the blister cover cannot be provided with structures such as hooks, making it difficult to achieve a snap connection between the blister cover and the box body. In addition, the blister cover is relatively soft, and the blister cover is prone to warping at the joint between the blister air duct and the injection molding air duct, which makes it easy for air leakage to occur at the warped edge, and makes it easy for some air to be blown into the storage room without passing through the evaporator, making it difficult for the refrigerator to cool and the temperature to drop slowly. In addition, since it is difficult to form a connection structure such as a buckle on the blister cover, the blister cover is usually fixed to the box body with screws. However, too many screws are currently required for fixing the blister cover, which takes a long time to assemble, requires more consumables, and increases the cost. In addition, the existing blister cover has no limiting structure before fixing, which requires people to hold the blister cover with their hands during installation, making the installation inconvenient, and even requires multiple people to work together, resulting in a serious waste of personnel. Therefore, the present application proposes a refrigerator. Summary of the invention

[0126] The fan 33 may be disposed in the fan chamber. The fan causes the air in the storage room to flow through the return air port to the evaporator chamber to exchange heat with the evaporator, and after the heat exchange with the evaporator, the air flows back into the storage room through the fan chamber and the air outlet. The fan 33 can circulate the air to cool the high-temperature air in the storage room and then provide it to the storage room, so that the temperature of the storage room can be relatively low.

[0127] In the present application, the air duct assembly 4 may be located at the rear end of the inner container.

[0128] In this application, reference is made to Figure 5-Figure 7 The inner liner 102 may include an inner liner rear wall 1021 located at the rear end of the inner liner.

[0129] In the present application, when the evaporator cavity is formed between the air duct assembly and the inner container, the air duct assembly and the rear wall of the inner container form the evaporator cavity located between the air duct assembly and the inner container.

[0130] In the present application, when the return air outlet is formed between the air duct assembly and the inner container, the air duct assembly and the rear wall of the inner container form the return air outlet between the air duct assembly and the inner container.

[0131] In this application, reference is made to Figure 6-Figure 8 The air duct assembly may include an air duct cover plate 43 .

[0132] In the present application, the air duct cover plate 43 may be located at the front side of the air duct assembly.

[0133] In the present application, when the evaporator cavity is formed between the air duct assembly and the inner container, the air duct cover plate and the inner container form the evaporator cavity located between the air duct cover plate and the inner container.

[0134] In the present application, when the evaporator cavity is formed between the air duct assembly and the inner container, the air duct cover plate and the rear wall of the inner container form the evaporator cavity located between the air duct cover plate and the rear wall of the inner container.

[0135] In the present application, when the return air outlet is formed between the air duct assembly and the inner tank, the air duct cover plate and the inner tank form the return air outlet located between the air duct cover plate and the inner tank.

[0136] In the present application, when the return air outlet is formed between the air duct assembly and the inner tank, the air duct cover plate and the rear wall of the inner tank form the return air outlet located between the air duct cover plate and the rear wall of the inner tank.

[0137] In this application, reference is made to Figure 6-Figure 8 The air duct assembly may include an air duct base 44. The air duct base may be located behind the air duct cover.

[0138] In this application, reference is made to Figure 6-Figure 8 The air duct base 44 and the air duct cover 43 form a fan cavity located therebetween.

[0140] In this application, reference is made to Figure 6-Figure 8 The air duct assembly may include a fan fixing member 45. The fan may be fixed on the fan fixing member.

[0141] In the present application, the fan fixing member may be located behind the air duct cover.

[0142] In the present application, the fan fixing member may be located between the air duct cover and the air duct base.

[0146] In this application, reference is made to Figure 6-Figure 8 The air duct cover plate may include a second cover plate 432 .

[0147] In the present application, the second cover plate can be formed by blister molding, so that the second cover plate can be a blister molded part.

[0148] The blister-formed air duct cover is simple to form and has obvious price advantages. However, due to the blister process, the blister-formed air duct cover cannot form a connection structure such as a hook, making it difficult for the blister-formed air duct cover to be connected to the box body.

[0149] The blister-molded air duct cover is relatively soft, and the joints between the blister-molded air duct cover and the injection-molded air duct cover are prone to warping, which makes it easy for air leakage to occur at the warped edges. It is easy for some air to be unable to flow through the evaporator and be blown into the storage room, making it difficult for the refrigerator to cool and the temperature to drop slowly.

[0150] In addition, since it is difficult to form a connection structure such as a buckle on the blister-formed cover, the blister-formed cover is usually fixed to the box body with screws. However, too many screws are currently required to fix the blister cover, which takes a long time to assemble, requires more consumables, and increases costs.

[0151] Furthermore, the existing blister cover has no limiting structure before being fixed, so that the blister cover needs to be supported by hand during installation, which makes installation inconvenient and even requires multiple people to work together, resulting in serious waste of manpower.

[0152] In this application, reference is made to Figure 9-11 , the first cover plate 431 may include a first cover plate body 4311 .

[0153] In this application, reference is made to Figure 9-11 , the first cover plate 431 may include a connecting plate 4312 .

[0154] In the present application, the connection plate can be connected to the rear of the first cover body. The connection plate and the first cover body can define an insertion portion 4313 located between the first cover body and the connection plate.

[0155] In this application, reference is made to Figure 9-11 A plug-in port 43131 may be provided at the bottom end of the plug-in portion.

[0156] In this application, reference is made to Figure 9-11 The top end of the second cover plate 432 can be inserted into the plug-in portion through the plug-in interface.

[0157] In the present application, the second cover plate may be located in front of the connecting plate. The second cover plate may be connected to the connecting plate.

[0158] The present application inserts the top end of the second cover plate into the plug-in portion, which can prevent the top end of the second cover plate from warping, prevent a large gap from being formed between the bottom end of the first cover plate and the top end of the second cover plate, and prevent the air in the storage room from flowing into the fan through the gap instead of passing through the evaporator, causing the air temperature to be too high, thereby avoiding problems such as poor refrigeration effect and difficulty in lowering the temperature, thereby improving the refrigeration effect of the refrigerator and enhancing the user experience.

[0159] In the present application, the plug-in portion may be a plug-in slot, and both ends of the plug-in slot in the width direction of the box body may be blocked.

[0160] In this application, reference is made to Figure 12-Figure 15 The refrigerator may include a first connector 51. The first connector may fix the connecting plate and the second cover plate on the box body.

[0161] In this application, reference is made to Figure 12-Figure 15 , a first through hole 43121 may be formed on the connecting plate.

[0162] In the present application, the first through hole 43121 may penetrate the connecting plate in the front-rear direction of the connecting plate.

[0163] In this application, reference is made to Figure 12-Figure 15 , a second through hole 4321 may be formed on the second cover plate.
