In the embodiment, a centrifugal fan is adopted, the centrifugal fan is arranged in the air duct 2, and the axial air inlet side of the centrifugal fan is opposite to the air inlet 13; the cooling air enters the circumferential air inlet side of the centrifugal fan from the air inlet 13, and then enters the air duct 2 from the radial air outlet side of the centrifugal fan. The air duct cover plate 15 is provided with a first air outlet 11 and a second air outlet 12, and the cooling capacity in the air duct 2 is transferred into the room through the first air outlet 11 and the second air outlet 12. It should be noted that, the setting positions of the first air outlet 11, the second air outlet 12 and the air inlet 13 may be adjusted correspondingly according to different fans or different air supply modes.

In this embodiment, the air duct 2 further includes a partition 20, the partition 20 is disposed at the lower side of the air inlet 13, the partition 20 divides the air duct into a first air-dividing duct 21 that is communicated with the first air outlet 11 and a second air-dividing duct 22 that is communicated with the second air outlet 12, the partition 20 is disposed at a position of a lower portion of the air duct 2, an upper air duct is formed at an upper side of the partition 20, the upper air duct is simultaneously communicated with the first air-dividing duct 21 and the second air-dividing duct 22, and air from a radial air outlet of the fan enters the upper air duct first, and is then distributed into the first air-dividing duct 21 and the second air-dividing duct 22 under the action of the air-dividing member 31.

The partition 20 extends in the vertical direction, the bottom end of the partition 20 is fixed at the bottom of the housing 1, and the top end of the partition 20 extends toward the air inlet 13 and is spaced from the air inlet 13 by a certain distance, that is, the top end of the partition 20 is located at the lower side of the air inlet 13.

It should be noted that, the air duct cover 15 is further provided with other air outlets, all the air outlets may be generally divided into two groups according to the positional relationship, and the two groups of air outlets are distributed on the left and right sides of the partition 20 with the extending direction of the partition 20 as the center. The inner container is also provided with a partition plate arranged in the compartment, the partition plate divides the compartment into a first compartment and a second compartment, a group of air outlets arranged on the left side of the partition piece 20 are used for cooling the first compartment, a group of air outlets arranged on the right side of the partition piece 20 are used for cooling the second compartment, and the two groups of air outlets are respectively used for cooling different compartments.

In this embodiment, as shown in fig. 1, three air outlets are provided in the left group, three air outlets are provided in the right group, the first air outlet 11 is located at the lowest side of the left group, and the second air outlet 12 is located at the lowest side of the right group. The first air outlet 11 and the second air outlet 12 are located at both sides of the partition 20. One air outlet close to the upper part in the left air outlet group is directly communicated with the upper air duct, and one air outlet close to the upper part in the right air outlet group is also directly communicated with the upper air duct.

In the prior art, the cooling capacity of the first compartment and the cooling capacity of the second compartment are basically equal, and the first air distribution duct 21 and the second air distribution duct 22 are symmetrically arranged, so that the air quantity entering from the air inlet can be basically equally distributed into the two air distribution ducts. However, in the practical process, since the fan is a centrifugal fan, the air exiting from the radial air outlet of the centrifugal fan easily forms a vortex at some parts, such as the partition 20 or the top of the air duct, and finally causes different transmission amounts of cold in the two compartments, which affects the use of users after long-time operation.

In addition, since different articles are stored in the first compartment and the second compartment, the amount of cold consumed is different for different stored articles and different types of articles. Therefore, the cooling effect in different compartments is also affected in the state that the air output of the first air outlet 11 and the second air outlet 12 is unchanged, thereby affecting the use experience of the user.

Therefore, in order to conveniently realize the adjustment of the cooling capacity in the first compartment and the second compartment, in this embodiment, an air distribution module 3 is further provided, where the air distribution module 3 includes a driving mechanism and an air distributing member 31 rotatably installed in the air duct 2, and the air distributing member 31 realizes the distribution of the cooling capacity entering from the air inlet 13 between the first air outlet 11 and the second air outlet 12 in the swinging process.

As shown in fig. 2-4, the air dividing member 31 is disposed at the lower side of the air inlet 13, and has a swing plate 311 extending freely toward the air inlet 13, the first air outlet 11 and the second air outlet 12 are disposed at opposite sides of the swing plate 311, and the swing plate 311 swings between the first air outlet 11 and the second air outlet 12 to control the distribution of cooling capacity between the first air outlet 11 and the second air outlet 12. In the initial state, the swing plate 311 extends in the vertical direction and points to the air inlet 13, the swing plate 311 is located directly below the air inlet 13, and an extension line of the swing plate 311 extending in the vertical direction bisects the air inlet 13, so that the average distribution of the cooling capacity between the two air outlets can be ensured.

In a specific use process, after the temperature in one of the compartments increases, the wind distributing member 31 can make a swinging adjustment of the position. Assuming that more cooling capacity is required in the first chamber after the temperature in the first chamber increases during use, the swing plate 311 swings in a direction to increase the air output of the first air outlet 11, and during actual use, the swing plate 311 swings in a direction to increase the inlet of the first air distribution duct 21 during swing due to being arranged between the first air distribution duct 21 and the second air distribution duct 22, so that the air output of the first air outlet 11 is increased by increasing the cooling capacity entering the first air distribution duct 21.

In this embodiment, the swing plate 311 is disposed between the partition 20 and the air inlet 13, the air dividing member 31 further has a pivot portion 312 rotatably engaged with the housing 1, and the swing plate 311 is fixed to the pivot portion 312. The pivot part 312 can be rotatably installed on the housing 1, the pivot part 312 is arranged between the partition 20 and the air inlet 13, and a gap can be arranged between the pivot part 312 and the partition 20; it is of course also possible to provide the pivot 312 on top of the partition 20.

As shown in fig. 4, the air volume distribution module 3 further has a module case 34 in the present embodiment, and the module case 34 is fixed to the case 1 and is disposed between the partition 20 and the air intake 13. The pivot 312 is rotatably mounted to the module housing 34.

As a preferred solution, the wind dividing member 31 is rotatably mounted on the module housing 34, the module housing 34 is fixed on the partition member 20, the pivot portion 312 is disposed at the top of the partition member 20 in the vertical direction, and the swing plate 311 is fixed on the pivot portion 312, that is, the swing plate 311 is a plate-like structure extending from the top of the partition member 20 toward the air inlet 13. The swing plate 311 may be regarded as a portion of the partition 20 extending in the direction of the air inlet 13, and since the swing plate 311 is rotatable, the sizes of the inlets of the first and second branch air ducts 21 and 22 partitioned by the partition 20 are also adjusted according to the swing of the swing plate 311.

The swing plate 311 actually affects the sizes of the inlet of the first air distribution duct 21 and the inlet of the second air distribution duct 22 during the swing process, thereby affecting the air output between the first air outlet 11 and the second air outlet 12. When the air-dividing member 31 swings toward the first air duct 21, the inlet of the first air-dividing duct 21 decreases, and the inlet of the corresponding second air-dividing duct 22 increases, and at this time, the air-out volume of the first air outlet 11 decreases, and the air-out volume of the second air outlet 12 increases. When the air dividing member 31 swings toward the second air dividing duct 22, the inlet of the second air dividing duct 22 decreases, and the inlet of the first air dividing duct 21 correspondingly increases. At this time, the air output of the first air outlet 11 increases, and the air output of the second air outlet 12 decreases.

As a preferred solution, the module housing 34 is detachably mounted and fixed on the partition 20, and the above structure is convenient for mounting and fixing the air distribution module 3 in the air duct assembly, so as to facilitate production and manufacture.

For the convenience of installing and fixing the module housing 34, the partition 20 is further provided with an avoidance groove adapted to the module housing 34, the module housing 34 is positioned in the avoidance groove, and the pivot portion 312 is exactly located at the top of the partition 20 in the vertical direction after the module housing 34 is installed and fixed.

Further, as shown in fig. 4, for conveniently realizing the operation of the swinging plate 311, the air distributing member 31 further has a pushing portion 313 disposed on the pivoting portion 312, the pushing portion 313 rotates synchronously with the swinging plate 311, the pushing portion 313 may be disposed in a housing cavity 340 in the module housing 34, the pushing portion 313 swings in the housing cavity 340, the air distributing module further has a driving mechanism for controlling the rotation of the air distributing member 31, the driving mechanism includes a pushing unit 33, the pushing unit 33 is disposed in the housing cavity 340, and the pushing unit 33 controls the swinging of the pushing portion 313, thereby controlling the swinging of the swinging plate 311 in the air duct 2.

In order to better control the swing of the swing plate 311 by the pushing portion 313, the pushing portion 313 is a plate structure extending from the pivot portion 312 in a direction away from the swing plate 311, and the length of the swing plate 311 extending in the extending direction thereof is longer than the length of the pushing portion 313 extending in the extending direction thereof.

The swing plate 311 and the pushing portion 313 extend from the pivoting portion 312 to two sides away from each other, so that the position of the pushing portion 313 can intuitively reflect the position of the swing plate 311, thereby realizing more intuitive control of the swing plate 311. Setting the extension length of the swing plate 311 to be larger than the extension length of the pushing portion 313 achieves that a large variation of the swing plate 311 can be achieved when a small variation of the pushing portion 313 occurs.

Further, as shown in fig. 4, in order to better realize driving of the swing plate 311, the air distribution module 3 further has a slider 32 matched with the pushing unit 33, where the slider 32 is slidably disposed in the accommodating groove 340, and the slider 32 is slidably disposed in the left-right direction under the action of the pushing unit 33, and when the slider 32 slides in the left-right direction, the slider 32 can drive the pushing portion 313 to swing left and right, so as to drive the swing plate 311 to swing between the first air outlet 11 and the second air outlet 12.

The swinging of the swinging plate 311 is driven by the sliding of the sliding member 32 in the linear direction, so that the rotation of the swinging plate 311 can be controlled better. Since the pushing unit 33 is generally linearly driven in the prior art, it is inconvenient to control the swing plate 311 swinging in an arc shape by the linearly driven pushing unit 33, and in this embodiment of the present application, the swing of the swing plate 311 swinging in an arc shape is controlled by the linearly driven pushing unit 33 by the arrangement of the sliding member 32.

Specifically, as shown in fig. 4, the sliding member 32 is provided with a sliding rod 321 extending in the vertical direction, the sliding rod 321 is provided with a sliding rod sliding hole 320 extending in the vertical direction, the pushing portion 313 is provided with a sliding block protrusion 314 slidingly engaged with the sliding rod sliding hole 320, when the sliding member 32 slides in the horizontal direction, the sliding rod 321 also slides in the horizontal direction, when the sliding rod 321 moves, the sliding block protrusion 314 is driven to move in the horizontal direction, and at the same time, the sliding block protrusion 314 slides up and down in the sliding rod sliding hole 320 of the sliding rod 321, that is, the sliding block protrusion 314 simultaneously moves up and down and horizontally under the action of the sliding rod 321, that is, the sliding block protrusion 314 is actually in the completed arc-shaped rotation, so as to be capable of driving the swinging plate 311 to rotate.

The above embodiment gives a solution in which the rotation of the swing plate 311 is controlled by the cooperation of the slider 32 and the pushing portion 313, and in another embodiment, the slider 32 may also be directly cooperated with the swing plate 311 to directly control the swing plate 311.

In particular, as shown in fig. 5 to 7, in another embodiment, the driving mechanism further includes a connecting member 35 rotatably connected to the swing plate 311, and a sliding hole 351 is further provided on the connecting member 35, where the sliding hole 351 is disposed to extend in a direction perpendicular to the sliding direction of the sliding member 32; the sliding member 32 is provided with a sliding rod 321 slidably engaged with the sliding hole 351.

In this embodiment, when the sliding member 32 slides in the horizontal direction, the sliding rod 321 is driven to slide in the horizontal direction, and when the sliding rod 321 slides, the connecting member 35 is driven to move in the horizontal direction, and meanwhile, the connecting member 35 is rotatably mounted on the swinging plate 311, and the swinging plate 311 can only rotate; therefore, when the connecting piece 35 slides along the horizontal direction, the sliding hole 351 on the connecting piece 35 is driven to slide up and down along the sliding rod 321, that is, the connecting piece 35 slides along the horizontal direction and slides along the vertical direction simultaneously under the action of the sliding piece 32, so that one end of the connecting piece 35 is actually in the complete arc-shaped rotation.

By realizing the rotation control of the swing plate 311 by the cooperation of the slider 32 and the swing plate 311, the swing direction of the swing plate 311 can be controlled more intuitively. In this embodiment, the connecting member 35 is rotatably connected to the swing plate 311 at an end far from the pivot portion 312. In order to more effectively control the swing plate 311, the connecting member 35 is rotatably connected to an end of the swing plate 311 near the pivot portion 312. The arrangement of such a structure enables the swing plate 311 to swing in a larger size when the slider 32 slides a small distance, improving the control efficiency.

In this embodiment, as shown in fig. 7, the connecting member 35 is rotatably connected to the end of the swing plate 311 away from the pivot portion 312, that is, the connecting member 35 is rotatably connected to the free end of the swing plate 311, so that the arrangement of the structure can realize slower control of the connecting member 35, thereby realizing more accurate adjustment of temperature.

Further, in order to realize automatic temperature balance, that is, the swinging direction of the air distributing member 31 in the air distributing module can be automatically regulated and controlled according to the specific temperatures of different compartments. In this embodiment, the pushing unit 33 is configured as a temperature-changing structure, which is configured to deform according to the temperature change of the cooling space of the air outlet, so as to drive the air distributing member 31 to rotate to control the air output of the air outlet.

As shown in fig. 3 or 7, the temperature-changing structure includes a thermal expansion member 331 that cooperates with the air distribution member 31 and a temperature sensing member 332 that is used for obtaining the temperature in the cooling chamber, where the temperature sensing member 332 of the temperature-changing structure is disposed in the corresponding chamber in an extending manner, and when the temperature in the chamber increases, the temperature sensing member 332 is heated, at this time, the thermal expansion member 331 expands and pushes the air distribution member 31 to swing in a direction of increasing the air output of the air outlet, where the air outlet is the air outlet that enters the chamber.

After the temperature sensing member 332 is cooled, the thermal expansion member 331 contracts in a direction away from the air dividing member 31, and drives the air dividing member 31 to move so as to reduce the air output of the air outlet, thereby reducing the supply of cold in the cooling chamber.

The temperature state in the cooling space can be timely obtained through the arrangement of the temperature change structure, and the air distributing piece 31 is controlled to swing towards the direction of increasing the air outlet volume of the air outlet after the temperature in the cooling space is increased, so that the increase of the cooling capacity supply in the cooling space is realized.
