[0076] The heat insulation foam has a certain thickness, and the avoiding part is a groove opened on the side of the heat insulation piece 14 facing the air duct cover plate 15. The avoiding part is used for accommodating electronic components, and the first wire slot 145 is used for accommodating the power cable of the electronic components, that is, the thickness space of the heat insulation foam is used to accommodate the electronic components and the cable, which can reduce the space occupation of the refrigeration compartment 41, make the heat insulation piece 14 and the air duct cover plate 15 compactly installed, improve the flatness of the air duct cover plate 15, and have better appearance effect.

[0077] Specifically, the avoiding part includes a second avoiding groove 142, and the first supporting part 12 is accommodated in the containing space defined by the second avoiding groove 142 and the air duct cover plate 15. Alternatively, the second avoiding groove 142 penetrates the heat insulation piece 14 along the width direction of the refrigeration compartment 41.

[0078] Referring toFigure 1 And Figure 3 The refrigerator air duct assembly provided by the embodiment of the utility model still includes a sterilization module 16, the avoiding part includes a third avoiding groove 143, and the sterilization module 16 is accommodated in the containing space defined by the third avoiding groove 143 and the air duct cover plate 15. The air duct cover plate 15 is provided with a hollow part 155 corresponding to the position of the sterilization module 16. The sterilization module 16 can be a module with a sterilization function such as DPS or AST without limitation.

[0079] The third avoiding groove 143 is adapted to the shape of the sterilization module 16. The sterilization module 16 is accommodated in the third avoiding groove 143, that is, the sterilization module 16 is accommodated in the thickness space of the heat insulation foam, so that the space occupation of the refrigeration compartment 41 can be reduced, the heat insulation piece 14 and the air duct cover plate 15 can be installed compactly, the flatness of the air duct cover plate 15 can be improved, and a better appearance effect can be achieved.

[0080] Because the heat insulation foam has a certain thickness, the first avoiding groove 141, the second avoiding groove 142 and the third avoiding groove 143 are arranged on the side of the heat insulation foam facing the air duct cover plate 15, a certain thickness of the heat insulation foam can be reserved, the first supporting piece 12, the second supporting piece 13 and the sterilization module 16 can be encapsulated inside the heat insulation foam and the air duct cover plate 15, compact cooperation of multiple components can be achieved, and the side of the heat insulation foam away from the air duct cover plate 15 is a flat surface and the side of the air duct cover plate 15 away from the heat insulation foam is also a flat surface.

[0081] Referring to Figure 2 And Figure 6 In the embodiment of the utility model, the heat insulation piece 14 has a first heat insulation part 14a and a second heat insulation part 14b connected in sequence along the airflow direction of the top air duct 101. The first heat insulation part 14a and the second heat insulation part 14b are both inclined downward along the airflow direction. The first heat insulation part 14a is arranged opposite to the evaporator, and the inclination angle of the second heat insulation part 14b is greater than that of the first heat insulation part 14a. The third avoiding groove 143 is arranged on the second heat insulation part 14b.

[0082] It can be understood that the first heat insulation part 14a and the second heat insulation part 14b are inclined relative to the horizontal plane. The air duct cover plate 15 is attached to the heat insulation piece 14, that is, the air duct cover plate 15 has two plate bodies with an angle arranged conformally with the first heat insulation part 14a and the second heat insulation part 14b.

[0083] Specifically, the first heat insulation part 14a and the second heat insulation part 14b are both arranged to be inclined downward along the airflow direction towards one side of the air duct cover plate 15 and away from the other side of the air duct cover plate 15, forming a top air duct 101 inclined downward along the airflow direction, which is helpful for the flow of cold air in the air duct and facilitates the outflow of defrosting water of the evaporator 2. The third avoiding groove 143 is arranged in the second heat insulation part 14b, which can keep the first heat insulation part 14a corresponding to the evaporator 2 to have a larger thickness, ensuring the heat insulation effect, and is also helpful for the sterilization module 16 to release sterilization substances to the middle area of the refrigeration compartment.

[0084] As shown in Figure 2 The refrigerator air duct assembly provided by the embodiment of the utility model further includes a condensed water collecting piece 17. The condensed water collecting piece 17 is sequentially provided with a flow guide part 171 and a water collecting part 172 along the airflow direction. The flow guide part 171 and the water collecting part 172 are arranged to be inclined downward along the airflow direction, and the inclination angle of the water collecting part 172 is greater than that of the flow guide part 171. The first heat insulation part 14a is attached to the flow guide part 171, and the second heat insulation part 14b is attached to the water collecting part 172. The inclination angle of the water collecting part 172 is greater than that of one side of the second heat insulation part 14b towards the air duct cover plate 15.

[0085] Specifically, the two sides of the heat insulation piece 14 are respectively attached to the condensed water collecting piece 17 and the air duct cover plate 15. The side of the heat insulation piece 14 away from the air duct cover plate 15 is conformally designed with the condensed water collecting piece 17. The inclination angle of the side of the first heat insulation part 14a away from the air duct cover plate 15 is the same as that of the side of the first heat insulation part 14a towards the air duct cover plate 15. The inclination angle of the side of the second heat insulation part 14b away from the air duct cover plate 15 is greater than that of the side of the second heat insulation part 14b towards the air duct cover plate 15. In this way, without reducing the effective use space of the refrigeration compartment 41, the second heat insulation part 14b can have sufficient thickness at the position corresponding to the third avoiding groove 143, so as to ensure the heat insulation effect.

[0086] The heating piece is arranged in the flow guide part 171, or the flow guide part 171 and the water collecting part 172 are both provided with the heating piece. The side of the heat insulation piece 14 away from the air duct cover plate 15 is provided with a second wire slot 146 for accommodating the power cable of the heating piece. The heat generated by the heating piece can defrost the evaporator 2, and the defrosting water drops on the flow guide part 171 and flows to the water collecting part 172 along the flow guide part 171. The bottom end of the water collecting part 172 is used to connect a drain pipe, so that the defrosting water is discharged out of the refrigerator through the drain pipe. The first heat insulation part 14a and the second heat insulation part 14b can prevent the heating piece from affecting the temperature in the refrigeration compartment when heating.

[0087] As shown in Figure 2 and Figure 3As shown, the refrigerator air duct assembly further comprises a return air outlet structure 18, which is mounted at one end of the two side plates 11 away from the rear wall surface of the refrigeration compartment 41. The top air duct 101 is adapted to be provided with the fan assembly 5. Under the action of the fan assembly 5, the air in the refrigeration compartment 41 enters the top air duct 101 from the return air outlet structure 18, flows obliquely downward along the top air duct 101 through the evaporator 2, enters the back air duct assembly from the outlet of the top air duct 101, and enters the refrigeration compartment 41 from the air outlet provided on the back air duct assembly.

[0088] As Figure 10 As shown, the refrigerator comprises a cabinet 4, a back air duct assembly 3 and a top air duct assembly 1. The top air duct assembly 1 is the refrigerator air duct assembly of any of the above embodiments. The cabinet 4 is provided with a refrigeration compartment 41, the top air duct assembly 1 is mounted on the top of the refrigeration compartment 41, and the back air duct assembly 3 is mounted on the rear wall surface of the refrigeration compartment 41 and connected with the top air duct assembly 1. Among them, the outlet of the top air duct 101 is defined between the heat insulation piece 14 and the rear wall surface of the refrigeration compartment 41, and the outlet of the top air duct 101 is adapted to be connected with the inlet of the back air duct assembly.
