The air duct assembly 50 may provide a path for the cooling system to deliver cool air into the refrigerator 1, for example, the cool air generated by the cooling system may exchange heat with air in the cool air supply chamber 21 to reduce the temperature of the air in the cool air supply chamber 21.

The air inlet of the first air duct 23 and the air inlet of the second air duct 25 are both communicated with the cold air supply chamber 21, and the air outlet of the first air duct 23 and the air outlet of the second air duct 25 are both communicated with the refrigerating chamber 11, so that cold air in the cold air supply chamber 21 can enter the refrigerating chamber 11 through the first air duct 23 and the second air duct 25 to provide cold air for the refrigerating chamber 11. In addition, the air duct assembly 50 is provided with the first air duct 23 and the second air duct 25 to provide cold air for the refrigerating chamber 11, so that more cold air can be provided for the refrigerating chamber 11, and the volume of the refrigerating chamber 11 can be designed to be larger, so that the requirement of a user on a large-capacity refrigerator can be met.

The air inlet of the third air duct 27 is communicated with the cold air supply chamber 21, and the air outlet of the third air duct 27 is communicated with the storage chamber 13, so that cold air in the cold air supply chamber 21 can enter the storage chamber 13 through the third air duct 27 to provide cold air for the storage chamber 13.

The air outlet of the first air duct 23 and the air outlet of the second air duct 25 are located at different sides of the air duct assembly 50, so that the cold air in the cold air supply chamber 21 can enter the refrigerating chamber 11 from different sides of the air duct plate 35 to cool different areas in the refrigerating chamber 11, and the temperature in the refrigerating chamber 11 can be more uniform.

The air duct assembly 50 includes a first air door 29, a second air door 31 and a third air door 33, the first air door 29 is disposed in the first air duct 23, the second air door 31 is disposed in the second air duct 25, and the third air door 33 is disposed in the third air duct 27, so that the first air door 29, the second air door 31 and the third air door 33 can respectively control the air outlet of the first air duct 23, the second air duct 25 and the third air duct 27, thereby being helpful to more precisely control the temperature of the refrigerating chamber 11 and the storage chamber 13, and improving the refrigerating effect of the refrigerator 1. Compared with the mode of adjusting the size of the air opening to control the air output of the air channel and thus the temperature of the cold chamber in the refrigerator in the related art, in the embodiment of the utility model, the air door is arranged on each air channel, and the air outlet is controlled by the air door on each air channel, so that the temperature of the refrigerating chamber 11 and the temperature of the storage chamber 13 can be controlled more accurately.

Specifically, the first damper 29, the second damper 31, and the third damper 33 may be electric dampers, and are connected to a controller in an electrical connection or a signal connection. The first damper 29, the second damper 31 and the third damper 33 are operable independently of each other. The controller may control the first, second and third dampers 29, 31 and 33 to open or close the first, second and third air paths 23, 25 and 27, respectively.

When the temperature in the refrigerating compartment 11 is low, for example, when the real-time temperature in the refrigerating compartment 11 is less than or equal to the preset temperature of the refrigerating compartment 11, the first damper 29 and the second damper 31 may close the first air path 23 and the second air path 25, respectively, helping to prevent cold air from continuously entering the refrigerating compartment 11 through the first air path 23 and the second air path 25, resulting in a continuous decrease in the temperature in the refrigerating compartment 11. When the temperature in the refrigerating chamber 11 is high, for example, when the real-time temperature in the refrigerating chamber 11 is greater than the preset temperature of the refrigerating chamber 11, the first air door 29 and the second air door 31 may respectively conduct the first air duct 23 and the second air duct 25, and cool air may enter the refrigerating chamber 11 through the first air duct 23 and the second air duct 25 to cool the refrigerating chamber 11 until the refrigerating chamber 11 is maintained at the preset temperature of the refrigerating chamber 11, and the first air door 29 and the second air door 31 respectively close the first air duct 23 and the second air duct 25. It is understood that the preset temperature of the refrigerating chamber 11 may be a temperature interval.

When the temperature in the storage chamber 13 is low, for example, when the real-time temperature in the storage chamber 13 is less than or equal to the preset temperature of the storage chamber 13, the third air door 33 may stop the third air duct 27, so as to help avoid continuous cooling air entering the storage chamber 13 through the third air duct 27, resulting in continuous temperature decrease in the storage chamber 13. When the temperature in the storage chamber 13 is high, for example, when the real-time temperature in the storage chamber 13 is greater than the preset temperature of the storage chamber 13, the third air door 33 may be connected to the third air duct 27, and cold air enters the storage chamber 13 through the third air duct 27 to cool the storage chamber 13 until the storage chamber 13 is kept at the preset temperature of the storage chamber 13. It will be appreciated that the predetermined temperature of the storage compartment 13 may also be a temperature interval.

In some embodiments, the shape of the air duct assembly 50 may be adapted to the inner wall of the refrigerator 1 to provide the air duct assembly 50 as the inner wall of the refrigerating compartment 11, for example, the air duct assembly 50 may have a substantially quadrangular structure.

In some embodiments, the air duct assembly 50 may include an air duct plate 35, and the cold air supply plenum 21, the first air duct 23, the second air duct 25, and the third air duct 27 are all provided to the air duct plate 35.

That is, the air duct plate 35 may include a first air duct plate 351 and a second air duct plate 353.

Wherein the second air duct plate 353 can be located on a side of the first air duct plate 351 facing away from the door.

In an embodiment of the present utility model, the air duct assembly 50 may include a sealing member, which may be coupled to a side of the second air duct plate 353 facing away from the door, the sealing member surrounding the open cool air supply chamber 21, and the sealing member abuts the case 10 to form the sealed cool air supply chamber 21 when the air duct assembly 50 is mounted to the case 10. Wherein the sealing member may be a sealing sponge.

In some embodiments, the first damper 29 and the second damper 31 may be open simultaneously or closed simultaneously.

In other embodiments, the first damper 29 and the second damper 31 may be independently opened or independently closed, respectively.

In some embodiments, the controller may control the opening and closing degree of the first damper 29 and the second damper 31 to control the air output of the first air duct 23 and the second air duct 25.

In some embodiments, the air outlets of the first air duct 23 and the second air duct 25 may be located at opposite sides of the air duct assembly 50, respectively, so that cool air may enter the refrigerating compartment 11 through the opposite sides of the air duct assembly 50, so that the temperature of the refrigerating compartment 11 may be more uniform.

The air outlet of the first air duct 23 and the air outlet of the second air duct 25 are located at opposite sides of the air duct assembly 50, which may mean that the air outlet of the first air duct 23 and the air outlet of the second air duct 25 are located at left and right sides of the air duct assembly 50, or that the air outlet of the first air duct 23 and the air outlet of the second air duct 25 are located at upper and lower sides of the air duct assembly 50, respectively. The left and right sides of the air duct assembly 50 may correspond to the left and right sides of the refrigerator 1, and the upper and lower sides of the air duct assembly 50 may correspond to the upper and lower sides of the refrigerator 1.

In some embodiments, the first air duct 23 may include at least two air outlets, so that the air outlet area of the first air duct 23 may be increased, which helps to make the temperature of the refrigerating chamber 11 more uniform, and improves the refrigerating effect of the refrigerator 1. The first damper 29 may be located at an air inlet of the first air duct 23, so that the first damper 29 may control a plurality of air outlets of the first air duct 23.

The two air outlets of the first air duct 23 may be located on the same side of the air duct assembly 50 and disposed at intervals.

In some embodiments, the second air duct 25 may include at least two air outlets, so that the air outlet area of the second air duct 25 may be increased, which helps to make the temperature of the refrigerating chamber 11 more uniform, and improves the refrigerating effect of the refrigerator 1. The second damper 31 may be located at an air inlet of the second air duct 25, so that the second damper 31 may control a plurality of air outlets of the second air duct 25.

The two air outlets of the second air duct 25 may be located on the same side of the air duct assembly 50 and spaced apart from each other.

In some embodiments, the air duct assembly 50 may also include a refrigerator 37 and a blower 39, i.e., the refrigerator 37 in the refrigeration system may be assembled into the air duct assembly 50 with other structures of the air duct assembly 50, and the refrigerator compartment 11 and the storage compartment 13 may share the refrigerator 37 on the air duct assembly 50.

The refrigerator 37 may be located in the cool air supply chamber 21 to exchange heat with air in the cool air supply chamber 21, and reduce the temperature of the air in the cool air supply chamber 21 so that the air in the cool air supply chamber 21 may be converted into cool air. The fan 39 rotates to drive cool air to flow, and the cool air enters the refrigerating chamber 11 through the first air duct 23 and the second air duct 25 and enters the storage chamber 13 through the third air duct 27.

Wherein the refrigerator 37 may be an evaporator and the blower 39 may be a centrifugal blower.

In some embodiments, the blower 39 may be located between the first air duct plate 351 and the second air duct plate 353, and the first air duct plate 351 is provided with a vent hole in communication with the air supply chamber 21, so that the first air duct plate 351 and the second air duct plate 353 may protect the blower 39, help to avoid other structures from affecting the rotation of the blower 39, and cool air in the air supply chamber 21 may enter the air duct between the first air duct plate 351 and the second air duct plate 353 through the vent hole.

In some embodiments, the cold air supply chamber 21 may include a first air chamber 211 and a second air chamber 213 that are distributed on opposite sides of the refrigerator 37 and are connected, and the fan 39 may be located in the first air chamber 211, and the air inlet of the first air duct 23, the air inlet of the second air duct 25, and the air inlet of the third air duct 27 are connected to the first air chamber 211. The air duct assembly 50 is further provided with a first air return opening 41 and a second air return opening 43, wherein the first air return opening 41 is communicated with the refrigerating chamber 11 and the second air chamber 213, and the second air return opening 43 is communicated with the storing chamber 13 and the second air chamber 213.

In this way, a first cooling cycle may be formed between the refrigerating chamber 11 and the cooling air chamber 21, and a circulation path of the first cooling cycle is: the cool air in the first air chamber 211 enters the refrigerating chamber 11 through the first air duct 23 and the second air duct 25 and cools the refrigerating chamber 11, the cool air in the refrigerating chamber 11 enters the second air chamber 213 through the first air return opening 41 and exchanges heat with the refrigerator 37, the temperature of the cool air after heat exchange is reduced, and the cool air enters the first air chamber 211, thereby forming a first cooling cycle. Similarly, a second cooling cycle may be formed between the storage chamber 13 and the cooling air chamber 21, and the circulation path of the second cooling cycle is sequentially the first air chamber 211, the third air duct 27, the storage chamber 13, the second air return opening 43, and the second air chamber 213, and then enters the first air chamber 211.

In some embodiments, the air outlets of the first air return port 41, the second air return port 43 and the third air duct 27 may be located on one side of the air duct assembly 50 facing the bottom of the refrigerator 1, and the air outlets of the first air duct 23 and the second air duct 25 may be located on opposite sides of the air duct assembly 50, and away from the air outlets of the third air duct 27.

Since the air outlets of the first air return port 41, the second air return port 43 and the third air duct 27 are all located at one side of the air duct assembly 50 facing the bottom of the refrigerator 1, the air outlets of the first air duct 23 and the second air duct 25 may be located at both left and right sides in the refrigerator 1. Because the cool air from the air outlet generally has a descending trend, the air outlet of the first air duct 23 and the air outlet of the second air duct 25 are arranged on one side far away from the third air outlet, which is helpful for cooling the upper area in the refrigerating chamber 11, thereby being helpful for more uniform temperature in the refrigerating chamber 11.

In some embodiments, the first air return opening 41 and the second air return opening 43 may refer to air return openings separately provided on the air duct assembly 50, or may refer to air return openings formed by matching the air duct assembly 50 and the box 10 after the air duct assembly 50 is assembled on the box 10.

For the second air return opening 43, the air duct assembly 50 may be provided with a protruding structure facing the bottom of the refrigerator 1, a vent corresponding to and communicating with the second air return opening 43 is provided on a side of the storage chamber 13 facing away from the refrigerator door, and the protruding structure may be attached to a side of the storage chamber 13 facing away from the refrigerator door, so that the second air return opening 43 may be communicated with the vent.

In some embodiments, the first, second, and third dampers 29, 31, 33 are each disposed between the first and second air duct plates 351, 353 to help reduce the spatial position of the first, second, and third dampers 29, 31, 33 in the refrigerator compartment 11.

In some embodiments, at least one of the first air duct plate 351 and the second air duct plate 353 may be provided with a first boss 3531, a first mounting groove in communication with the first air duct 23 may be provided in the first boss 3531, and the first damper 29 is positioned in the first mounting groove, such that the thickness of the air duct assembly 50 may be locally thickened for mounting the first damper 29, helping to avoid the first air duct plate 351 and the second air duct plate 353 from integrally thickening to occupy more space in the fresh food compartment 11.

Wherein the first air duct plate 351 may be opposite to the door, and the second air duct plate 353 is located at a side of the first air duct plate 351 facing away from the door.

In the embodiment of the utility model, the first boss 3531 may be disposed on the second air duct plate 353, and the first boss 3531 may be disposed on a side of the second air duct plate 353 away from the refrigerator door, so that the space occupied by the first boss 3531 in the refrigerating chamber 11 is reduced, and the user cannot see the first boss 3531, thereby improving the aesthetic property of the refrigerator 1. In addition, the first boss 3531 may also serve as a positioning structure to facilitate the assembly of the air duct assembly 50 to the case 10. For example, the inner wall of the refrigerator 1 or a structure (e.g., foam) attached to the inner wall of the refrigerator 1 may be provided with a groove, and the first boss 3531 may be embedded in the groove.
