Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0072] The refrigerator is provided with an air inlet and an air outlet, and the air inlet and the air outlet are respectively communicated with the heat exchange cavity of the refrigerator. The gas outside the refrigerator can enter the heat exchange cavity through the air inlet, and then be guided to the outside of the refrigerator through the air outlet. The gas entering the heat exchange cavity through the air inlet is used to cool the condenser and compressor in the heat exchange cavity of the refrigerator. The air outlet is used to guide the gas inside the refrigerator to the outside of the refrigerator, so as to guide the high-temperature gas in the heat exchange cavity to the outside of the refrigerator, thereby realizing the heat dissipation of the condenser and compressor.

[0073] In the related art, the air inlet and the air outlet are arranged on the bottom plate of the refrigerator. During long-term use of the refrigerator, the air inlet of the refrigerator will be blocked by dust, causing the communication between the air inlet and the heat exchange cavity to be blocked, thereby causing the heat dissipation of the condenser and compressor to be poor, and the refrigeration effect of the refrigerator to be poor.

[0074] In the refrigerator provided by the embodiments of the present application, the foot is arranged at the bottom of the bottom plate, and the foot is used to support the cabinet. The air guide channel is formed at the bottom of the bottom plate, and the air guide channel is located outside the cabinet and is used to communicate with and exchange heat with the heat exchange cavity, so as to reduce the internal temperature of the heat exchange cavity and reduce the energy consumption of the refrigerator.

The recess is recessed towards the side close to the door body, and the groove of the recess is located on the side away from the door body. The space occupation of the cabinet can be reduced. The communication hole is arranged in the groove wall and is communicated with the heat exchange cavity. The communication hole is used to communicate the heat exchange cavity with the outside of the cabinet, so that the heat exchange cavity and the outside of the cabinet can exchange heat through the communication hole, thereby reducing the internal temperature of the heat exchange cavity to cool the condenser and compressor in the heat exchange cavity.

[0075] Therefore, the refrigerator provided by the embodiment of the present application can solve the problem that the air inlet and the air outlet are easy to be blocked, which can cause the refrigeration effect of the refrigerator to be poor.

The air guide channel is located outside the cabinet 10 and is used for communicating with and exchanging heat with the heat exchange cavity 11, so that the internal temperature of the heat exchange cavity 11 is reduced, and the energy consumption of the refrigerator can be reduced. The bottom plate 200 forms the air guide channel at the bottom of the bottom plate 200, which can reduce the difficulty of setting the air guide channel.

[0081] It can be understood that the recess is provided, which can increase the contact area of the rear cover plate 100 with the outside of the refrigerator, the recess is recessed towards the side close to the door body 20, the slot opening of the recess is located at the side of the rear cover plate 100 away from the door body 20, which can reduce the space occupation of the cabinet 10, the slot wall of the recess is provided with the communication hole 104 in communication with the heat exchange cavity 11, the communication hole 104 is used for communicating the heat exchange cavity 11 with the outside of the cabinet 10, so that the heat exchange cavity 11 and the outside of the cabinet 10 can exchange heat through the communication hole 104, thereby the internal temperature of the heat exchange cavity 11 can be reduced to cool the condenser 400 and the compressor 500.

[0082] It should be noted that the recess extends to the bottom plate 200, and the recess communicates with the air guide channel.

[0083] It can be understood that the groove extends to the bottom plate 200, so that the groove is in communication with the air duct, so that the air flow in the heat exchange cavity 11 can be guided to the outside of the refrigerator through the connecting hole and the groove and the air duct.

[0084] Alternatively, the outside air flow in the air duct can pass through the groove and enter the heat exchange cavity 11 through the connecting hole to exchange heat with the heat exchange cavity 11.

[0085] As shown in Figure 7 The rear cover plate 100 provided by the embodiment of the present application includes a first plate body 101, a second plate body 102, and a transition plate body 103. The first plate body 101 is arranged on the cabinet 10 and connected with the bottom plate 200. The second plate body 102 is located between the first plate body 101 and the door body 20 along the depth direction of the cabinet 10 and is connected with the bottom plate 200. One end of the transition plate body 103 is connected with the first plate body 101, and the other end of the transition plate body 103 is connected with the second plate body 102.

[0086] It should be noted that the transition plate body 103 and the second plate body 102 enclose a groove, and the communication hole 104 is arranged on the second plate body 102.

[0087] It can be understood that the second plate body 102 is connected with the bottom plate 200, so that the groove extends to the bottom plate 200, thereby being in communication with the air duct to increase the contact area between the groove and the air duct. One end of the transition plate body 103 is connected with the first plate body 101, and the other end of the transition plate body 103 is connected with the second plate body 102, which can reduce the connection difficulty between the first plate body 101 and the second plate body 102. The transition plate body 103 and the second plate body 102 enclose the groove, which can reduce the difficulty of opening the groove to improve the processing efficiency of the groove. Compared with the related art in which the communication hole 104 is arranged at the bottom of the refrigerator, the communication hole 104 is arranged on the second plate body 102 in the present application, which can reduce the blockage of the communication hole 104 by dust at the bottom of the refrigerator, thereby reducing the blockage area of the heat exchange cavity 11 by dust to improve the heat exchange effect of the heat exchange cavity 11.

[0088] It should be noted that the communication hole 104 is arranged in multiple numbers, and the multiple communication holes 104 are arranged in the plate surface extension direction of the second plate body 102.

[0089] It can be understood that increasing the number of communication holes 104 can increase the contact area between the heat exchange cavity 11 and the external environment, thereby improving the heat dissipation efficiency of the heat exchange cavity 11.

[0090] It should be noted that the multiple communication holes 104 have multiple different arrangement modes, and the arrangement modes of the multiple communication holes 104 will be described in turn.

[0091] In one feasible implementation, a plurality of connecting holes 104 are spaced apart along the width direction of the refrigerator.

[0092] Understandably, the multiple connecting holes 104 are spaced apart along the width of the refrigerator, which can increase the airflow into the heat exchange chamber 11.

[0093] In another feasible implementation, a plurality of connecting holes 104 are spaced apart along the height direction of the refrigerator.

[0094] It is understandable that the multiple connecting holes 104 are spaced apart along the height of the refrigerator, which can increase the airflow into the heat exchange chamber 11 and reduce the blockage of the connecting holes 104 by dust at the bottom of the refrigerator, thereby improving the heat exchange effect of the heat exchange chamber 11.

[0095] In addition, in another feasible embodiment, some of the multiple connecting holes 104 are spaced apart along the width direction of the refrigerator, and the remaining multiple connecting holes 104 are spaced apart along the height direction of the refrigerator.

[0096] It is understandable that some of the multiple connecting holes 104 are spaced apart along the width direction of the refrigerator, and the remaining connecting holes 104 are spaced apart along the height direction of the refrigerator. This can increase the airflow into the heat exchange chamber 11 and reduce the blockage of the connecting holes 104 by dust at the bottom of the refrigerator, thereby improving the heat exchange effect of the heat exchange chamber 11.

[0097] It should be noted that there are multiple grooves, which are spaced apart along the width of the refrigerator.

[0098] Understandably, increasing the number of grooves increases the number of connecting holes 104, thereby increasing the airflow into the heat exchange chamber 11 and improving its heat dissipation efficiency. The spacing of multiple grooves along the width of the refrigerator reduces the processing difficulty of these grooves, thus increasing the utilization rate of the rear cover 100 surface area.

[0099] It should be noted that the number of grooves can be 2, 3, or other numbers, and there is no restriction. The selection can be made according to the actual needs of use, as long as the multiple grooves are spaced apart along the width of the refrigerator.

[0107] It should be noted that the first air guide channel is communicated with one of the grooves, and the second air guide channel is communicated with another of the grooves.

[0108] It can be understood that one of the grooves is communicated with the first air guide channel, which can improve the wind flow transportation efficiency between one of the grooves and the first air guide channel, and another of the grooves is communicated with the second air guide channel, which can improve the wind flow transportation efficiency between another of the grooves and the first air guide channel.

[0109] It should be noted that the first air guide and the second air guide have a plurality of different setting functions, and the setting functions of the first air guide and the second air guide will be illustrated in turn.

[0110] In a feasible implementation, the first air guide is used to form an air inlet channel, and the air inlet channel can guide the wind in the external environment to a groove in communication with the first air guide and then to the inside of the heat exchange cavity 11 through the communication hole 104.

[0132] It should be noted that the first depth h satisfies 8mm<h<12mm.

[0133] It should be noted that if the first depth h≤8mm, the depth of the groove will be shallower, so that the groove is easily blocked by dust, and the heat dissipation effect of the heat exchange cavity 11 will be poorer.

[0134] It should be noted that if the first depth h≥12mm, the depth of the groove will be deeper, so that the space occupation of the groove will be larger, which will cause the space occupation of the cabinet 10 to be larger, and the processing cost of the refrigerator to be higher.

[0135] It can be understood that the first depth h satisfies 8mm<h<12mm, which can reduce the occurrence of dust blocking the groove, and can reduce the space occupation of the groove, so as to reduce the processing cost of the refrigerator while ensuring the heat dissipation effect of the heat exchange cavity 11.

[0137] It should be noted that the second depth H satisfies 690mm<H<710mm.

[0138] It should be noted that if the second depth H≤690mm, the processing difficulty of the cabinet 10 will be larger, and the capacity of the storage compartment of the refrigerator will be smaller.

[0139] It should be noted that if the second depth H≥710mm, the space occupation of the cabinet 10 will be larger, and the processing cost of the refrigerator will be higher.

[0140] It can be understood that the second depth H satisfies 690mm<H<710mm, which can reduce the processing difficulty of the cabinet 10, and can reduce the space occupation of the cabinet 10 while ensuring the capacity of the storage compartment of the refrigerator, thereby reducing the processing cost of the refrigerator.

[0141] It should be noted that the value of the second depth H can be 692mm, 695mm, 698mm, 700mm, 712mm, 715mm, 717mm, or other depth values within the range of 690mm to 710mm, which is not limited herein and can be selected according to actual use requirements.
