Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an embodiment of a refrigeration apparatus of the present application, and fig. 2 is a schematic cross-sectional diagram of an embodiment of a cross-sectional line a-a in fig. 1. The refrigerating apparatus 10 may be a refrigerator or the like having a refrigerating and/or freezing function, and may be specifically an air-cooled refrigerator. The refrigeration unit 10 includes a tub 100, a first duct cover 102, a second duct cover 104, and a fan 106.

Specifically, the inner container 100 serves as a storage medium of the refrigeration device 10, and the inside of the inner container is a storage space of the refrigeration device 10. An article storage opening is formed at one side of the inner container 100, and a user can store or take out articles through the article storage opening formed in the inner container 100. The inner container 100 includes a rear wall panel 1000, and the rear wall panel 1000 of the inner container 100 may face a user when the user opens the door of the refrigeration apparatus 10.

The first duct cover 102 and the second duct cover 104 may be a single plate, and the first duct cover 102 and the second duct cover 104 are both disposed at an interval on one side of the rear wall 100, for example, at an interval on one side of the rear wall 100 facing the storage opening. And first air duct cover plate 102 is close to rear wall plate 1000 relative to second air duct cover plate 104, it can be said that the average distance between first air duct cover plate 102 and rear wall plate 1000 is smaller than the average distance between second air duct cover plate 104 and rear wall plate 100, the gaps between first air duct cover plate 102, second air duct cover plate 104 and rear wall plate 100 form a channel, and whether the channel is an air supply channel or an air suction channel may be determined according to a specific design. Further, the first duct cover 102 includes a first portion 1020 extending between the second duct cover 104 and the rear wall panel 1000, and a second portion 1022 located outside the second duct cover 104, the first portion 1020 is provided with an opening P; in this embodiment, the area between the first portion 1020 and the rear wall panel 1000 may be defined as a first area a1, the area between the second duct cover 104 and the first portion 1020 may be defined as a second area a2, and the openings P may be designed to allow the first area a1 and the second area a2 to communicate. The fan 106 (e.g., a centrifugal fan, etc.) is located within the first area a1, and corresponds to the position of the opening P. Preferably, the air inlet of the fan 106 corresponds to the position of the opening P.

On one hand, the first air duct cover plate 102 and the second air duct cover plate 104 are designed in a manner that air suction and air supply of the fan 106 can be well separated, noise of the fan 106 can be reduced, and air supply efficiency can be improved; on the other hand, the design of the first duct cover 102 close to the rear wall 1000 relative to the second duct cover 104 can reduce the thickness of the duct in the refrigeration equipment 10, so as to make more storage space and further increase the compartment volume of the refrigeration equipment 10.

In this embodiment, a first air supply passage 108 is formed between the second portion 1022 and the rear wall plate 1000, and the first air supply passage 108 communicates with the inner container 100. For example, as shown in fig. 1, the inner container 100 may be provided with a plurality of air inlets F, and the first air supply channel 108 is communicated with the air inlets F so as to supply air into the inner container 100 through the air inlets F. The cold air coming out of the air outlet of the fan 106 can be sent into the inner container 100 through the first air supply channel 108, and then the goods stored in the inner container 100 can be efficiently refrigerated. In order to reduce the air supply resistance and noise when the air outlet of the fan 106 supplies air to the first air supply passage 108, the central axis of the first air supply passage 108 is aligned with the air outlet of the fan 106. For example, the central axis of the first air supply channel 108 passes through the air outlet of the fan 106; preferably, a central axis of the air outlet of the fan 106 coincides with a central axis of the first air supply channel 108.

In one embodiment, in order to effectively isolate the inlet air from the outlet air of the fan 106, please continue to refer to fig. 2, the first portion 1020 of the first duct cover plate 102 includes a first plate 10200 and a second plate 10202 connected to each other, and both ends of the second plate 10202 are fixedly connected to the first plate 10200 and the second portion 1022, respectively; wherein, the second plate 10202 and the second portion 1022 are disposed substantially parallel to the rear wall panel 1000, and the opening P is disposed on the second plate 10202; the first plate 10200 is disposed obliquely to the rear wall plate 1000, and one end thereof is fixedly connected to the rear wall plate 1000.

In addition, as shown in fig. 2, the second plate 10202 may further include a flared constriction (not labeled) at the position of the opening P, the constriction is located in the first area a1, and the size of the opening of the constriction gradually decreases in the direction toward the air inlet of the fan 106, so as to gather the air flow to the air inlet of the fan 106. The constriction may be formed by a hollow ring or by two plates arranged opposite each other.

In the present embodiment, please refer to fig. 3 for easy assembly and shipment, and fig. 3 is a schematic structural diagram of an embodiment of the fixing assembly. The refrigeration device 10 provided by the present application further includes a fixing assembly 20 (not shown in fig. 2) for fixing the position of the fan 106, and one end of the fixing assembly 20 is fixedly connected to the second duct cover plate 104.

The fixing claw 200 may be designed to increase the fixing force between the fixing component 20 and the second air duct cover plate 104, and reduce the probability that the fixing component 20 falls off from the second air duct cover plate 104. While the stationary shaft 202 may extend from the second duct cover 104 into the first region a1, the stationary shaft 202 may be fixedly coupled to the housing of the fan 106 by screws, snaps, etc. to secure the fan 106 within the first region a 1. The fixed shaft 202 may extend in a straight line or a broken line, and may be specifically adjusted according to the surrounding spatial layout, which is not limited in the present application. Of course, in other application scenarios, the fixing claw 200 may be omitted, and the fixing shaft 202 may be directly fixedly connected to the second air duct cover plate 104 by screws or the like. Alternatively, an additional annular locking member is disposed at an end of the fixing shaft 202 close to the blower 106, and the annular locking member is sleeved on the periphery of the blower 106 to fix the position of the blower 106.

Referring again to fig. 1 and 2, the refrigeration device 10 provided by the present application further includes an evaporator 101, where the evaporator 101 mainly performs "heat absorption" to convert hot air into cold air and output the cold air. The evaporator 101 is positioned between the second air duct cover plate 104 and the rear wall plate 1000, and in the vertical direction, the evaporator 101 is positioned below the fan 106; for example, the fan 104 is located in the middle of the refrigeration appliance 10, and the evaporator 101 is located in the lower portion of the refrigeration appliance 10. In the present embodiment, the area where the evaporator 101 is located is communicated with the second area a2, and the cool air generated by the evaporator 101 can enter the first area a1 along the second area a2 in fig. 2 by the suction action of the fan 106, and then is conveyed to the inside of the first air supply passage 108 by the fan 106. The fan 106 and the evaporator 101 are arranged in a manner to increase the volume of the upper portion of the refrigeration apparatus 10.

Specifically, referring again to fig. 1, the refrigeration device 10 includes a first chamber 103 and a second chamber 105 spaced apart from each other in the left-right direction or in the up-down direction, and the first chamber 103 and the second chamber 105 may respectively include one inner container 100, or the inner containers 100 of the first chamber 103 and the second chamber 105 may be integrated. The first compartment 103 and the second compartment 105 may be divided into a plurality of storage spaces by shelves or drawers. One of the first chamber 103 and the second chamber 105 may be a refrigerating chamber, the other may be a freezing chamber, or both may be refrigerating chambers, or both may be freezing chambers, and the first chamber 103 and the second chamber 105 may be set according to actual requirements. The first air supply passage 108 may communicate with the first chamber 103, and the refrigeration apparatus 10 may further include a second air supply passage 107; only a portion of the second air supply duct 107 is schematically shown in fig. 1, and the second air supply duct 107, which is labeled as the area of the second chamber 105, is not shown in fig. 1. Both ends of the second air blowing passage 107 may communicate with the first air blowing passage 108 and the second chamber 105, respectively.

The communication can be realized by the following modes: a plurality of air inlets F are formed in a partial region of the first and second compartments 103 and 105 so that cool air can be introduced into the first and second compartments 103 and 105 through the air inlets F to cool the articles stored in the first and second compartments 103 and 105.

Alternatively, a plurality of air inlets F may be respectively disposed at the upper portions of the first chamber 103 and the second chamber 105, since the upper portion and the lower portion of the first chamber 103 are communicated and the upper portion and the lower portion of the second chamber 105 are communicated, the cold air entering from the air inlet F located at the upper portion may sink, the air of the entire first chamber 103 or the second chamber 105 is in a circulating state, and the air inlet F is designed in a manner sufficient to achieve temperature control.

Alternatively, the first air supply passage 108 may communicate with the freezing chamber, the second air supply passage 107 may communicate with the refrigerating chamber, and the fan 106 may be located at an intersection of extension lines of the first air supply passage 108 adjacent to the fan 106 and the second air supply passage 107 adjacent to the fan 106.

In addition, in this embodiment, the front surface of the air duct can be laid flat to realize wide air supply. For example, the horizontal width of the first blowing passage 108 at the position of the first chamber 103 may be equal to or greater than half the horizontal width of the first chamber 103; alternatively, the horizontal width of the second blowing passage 107 at the position of the second chamber 105 is equal to or greater than half the horizontal width of the second chamber 105.

Generally, in order to control the air volume in the air supply channel, an air door is generally arranged in the air supply channel, the air door can be an electric air door and the like, and the opening and closing degree of the air door can be adjusted; for example, the damper may be generally fully open, half open, closed, or the like. To improve the reliability of the air supply and reduce the occurrence of condensation, frost, etc., the damper in the second air supply passage 107 may be disposed close to the fan 106. Further, to save space, the second supply air passage 107 includes a third portion 1070 passing through the partition 109 between the first and second chambers 103 and 105, and a damper may be provided in the third portion 1070, the damper being in communication with the fan 106.

Further, taking fig. 1 as an example, since the second air supply passage 107 at the position of the second chamber 105 is located farther from the position of the fan 104, there is a problem of uneven air supply in the second chamber 105. To solve this problem, a plurality of guide ribs 301 may be introduced into the second air blowing passage 107, specifically, as shown in fig. 4, fig. 4 is a schematic structural view of an embodiment of the second air blowing passage and the guide ribs on the second chamber side in fig. 1. To reduce wind resistance, the outer edge of the guide rib 301 may be curved. In this embodiment, a plurality of guide grooves 303 are formed between the plurality of guide ribs 301, the guide grooves 303 include a first end (not shown) and a second end (not shown) that are oppositely disposed, and the first end is communicated with the air inlet F of the second chamber 105. In the present embodiment, the guide groove 303 may include a center line L1 perpendicular to the ground direction, and the guide groove 303 is symmetrically disposed about the center line L1.

Wherein at least part of the first end is provided with a plurality of guiding ribs 301 extending in different directions and/or at least part of the second end is provided with a plurality of guiding ribs 301 extending in different directions. The cold air in the second air supply channel 107 can be divided along the guide ribs 301 extending in different directions, so that the cold air can enter the second chamber 105 at different angles, and the uniformity of the cold air in the second chamber 105 is enhanced. In this embodiment, as shown in fig. 4, some of the guide ribs 301 extending in different directions may extend in a vertical direction, some of the guide ribs 301 may be disposed obliquely to the vertical direction, and the guide groove 303 may include a center line L1 in the vertical direction, and an end of the guide rib 301 close to the ground may be close to the center line L1 (i.e., an arrangement manner of the oblique guide rib 301 in fig. 4) relative to an end of the guide rib 301 away from the ground. The above-described design of the guide ribs 301 facilitates drainage.

In addition, the second end of at least part of the guide groove 303 is closed, and the design mode can reduce the situation of hot air back streaming so as to improve the refrigeration efficiency. Further, the closed guide groove 303 may be located at the periphery of the air inlet F at the corresponding position to reduce the influence of the closed guide groove on the air volume at the air inlet F.
