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 lowermost side of the left group, and the second air outlet 12 is located at the lowermost side of the right group. The first outlet port 11 and the second outlet port 12 are located at both sides of the partition 20. One air outlet close to the upper part of the left group of air outlets is directly communicated with the upper air duct, and one air outlet close to the upper part of the right group of air outlets is also directly communicated with the upper air duct.

In the prior art, the cooling capacity supply of the first chamber and the cooling capacity supply of the second chamber are equal in principle, and the first air dividing channel 21 and the second air dividing channel 22 are symmetrically arranged, so that the air quantity entering from the air inlet can be equally distributed into the two air dividing channels in principle. However, in the actual process, because the fan is a centrifugal fan, the wind coming out of the radial air outlet of the centrifugal fan is easy to form vortex flow at some parts such as the separator 20 or the top of the air duct, and finally, the cold transmission amount in the two compartments is different, and the use of users is influenced after long-time operation.

In addition, since different articles are stored in the first compartment and the second compartment, the amounts of stored articles and the amounts of consumed coldness are different depending on the types of articles. Therefore, under the state that the air output of the first air outlet 11 and the second air outlet 12 is not changed, the cooling effect in different rooms can be influenced, and the use experience of the user is influenced.

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 volume distribution module 3 is further provided, the air volume distribution module 3 includes a driving mechanism and an air distributing member 31 rotatably installed in the air duct 2, and the cooling capacity entering from the air inlet 13 is distributed between the first air outlet 11 and the second air outlet 12 in the swinging process of the air distributing member 31.

As shown in fig. 2 to 4, the air distributing member 31 is disposed at a 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 the cooling capacity between the first air outlet 11 and the second air outlet 12. In an initial state, the swinging plate 311 extends along the vertical direction and is directed to the air inlet 13, the swinging plate 311 is located right below the air inlet 13, and an extension line of the swinging plate 311 extending along the vertical direction bisects the air inlet 13, so that the cold energy can be uniformly distributed between the two air outlets.

In a specific use process, when the temperature in one of the compartments is increased, the air distributing member 31 can make a position swing adjustment. Assuming that after the temperature in the first compartment rises during use, more cold energy is needed in the first compartment, the swing plate 311 swings in the direction of increasing the air output of the first air outlet 11, and in the actual use process, the swing plate 311 swings in the direction of increasing the inlet of the first air dividing duct 21 during the swing process due to the fact that the swing plate is arranged between the first air dividing duct 21 and the second air dividing duct 22, and the air output entering the first air outlet 11 is increased by increasing the cold energy entering the first air dividing duct 21.

In this embodiment, the swing plate 311 is disposed between the partition 20 and the air inlet 13, the air distributing 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.

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

Preferably, the air distributing member 31 is rotatably mounted on a module housing 34, the module housing 34 is fixed on the partition 20, the pivot portion 312 is disposed at the top of the partition 20 in the vertical direction, and the swing plate 311 is fixed on the pivot portion 312, that is, the swing plate 311 is actually a plate-shaped structure extending from the top of the partition 20 to 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 branch air duct 21 and the second branch air duct 22 partitioned by the partition 20 are also adjusted in accordance with the swing of the swing plate 311.

The swing plate 311 actually influences the sizes of the inlet of the first sub-air duct 21 and the inlet of the second sub-air duct 22 during the swing process, and further influences the air output between the first air outlet 11 and the second air outlet 12. When the air dividing piece 31 swings towards the first air duct 21, the inlet of the first air dividing duct 21 is reduced, the inlet of the corresponding second air dividing duct 22 is increased, at this time, the air output of the first air outlet 11 is reduced, and the air output of the second air outlet 12 is increased. When the air distributing member 31 swings toward the second air distributing duct 22, the inlet of the second air distributing duct 22 decreases, and the inlet of the first air distributing duct 21 correspondingly increases. At this time, the air output of the first air outlet 11 is increased, and the air output of the second air outlet 12 is decreased.

Further, as shown in fig. 4, in order to conveniently realize the operation of the swing plate 311, the air distributing member 31 further has a pushing portion 313 arranged on the pivot portion 312, the pushing portion 313 and the swing plate 311 rotate synchronously, the pushing portion 313 may be arranged in the accommodating cavity 340 in the module housing 34, the pushing portion 313 swings in the accommodating cavity 340, the air volume distribution 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 arranged in the accommodating cavity 340, and the pushing unit 33 controls the swing of the swing plate 311 in the air duct 2 by controlling the swing of the pushing portion 313.

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

The swinging plate 311 and the pushing part 313 extend from the pivoting part 312 to two sides away from each other, so that the position of the pushing part 313 can visually reflect the position of the swinging plate 311, and the swinging plate 311 can be controlled more visually. Setting the extension length of the swing plate 311 to be longer than the extension length of the pushing portion 313 achieves a large variation of the swing plate 311 when a slight variation occurs in the pushing portion 313.

Further, as shown in fig. 4, in order to better drive the swing plate 311, the air volume distribution module 3 further includes a sliding member 32 engaged with the pushing unit 33, the sliding member 32 is slidably disposed in the accommodating groove 340, and the sliding member 32 is slidably disposed along the left and right direction under the action of the pushing unit 33, and when the sliding member 32 slides along the left and right direction, the sliding member 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 swinging plate 311 can be controlled to rotate better. In the prior art, since the pushing unit 33 is generally driven linearly, it is inconvenient to control the swinging plate 311 swinging in an arc shape by the pushing unit 33 driven linearly, and in this embodiment of the present application, the pushing unit 33 driven linearly controls the swinging plate 311 swinging in an arc shape by the arrangement of the sliding member 32.

Specifically, as shown in fig. 4, a sliding rod 321 is disposed on the sliding member 32 and extends in the vertical direction, a sliding rod sliding hole 320 is disposed on the sliding rod 321 and extends in the vertical direction, a sliding block protrusion 314 slidably engaged with the sliding rod sliding hole 320 is disposed on the pushing portion 313, 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 drives the sliding block protrusion 314 to move in the horizontal direction, and meanwhile, the sliding block protrusion 314 can slide up and down in the sliding rod sliding hole 320 of the sliding rod 321, that is, the sliding block protrusion 314 can simultaneously move up and down and move horizontally under the action of the sliding rod 321, that is, the sliding block protrusion 314 actually completes an arc-shaped rotation, so as to drive the rotation of the swinging plate 311.

The above-described embodiment provides a solution in which the control of the rotation of the swing plate 311 is achieved by the cooperation of the slider 32 and the pushing portion 313, and in another embodiment the slider 32 may also directly cooperate with the swing plate 311 to achieve direct control of the swing plate 311.

Specifically, 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, the connecting member 35 is further provided with a sliding hole 351, and the sliding hole 351 extends in a direction perpendicular to the sliding direction of the sliding member 32; the slider 32 is provided with a slide rod 321 slidably engaged with the slide hole 351.

In this embodiment, the sliding member 32 drives the sliding rod 321 to slide in the horizontal direction when sliding in the horizontal direction, the sliding rod 321 drives the connecting member 35 to move in the horizontal direction when sliding, 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 member 35 slides in the horizontal direction, the sliding hole 351 of the connecting member 35 will also slide up and down along the sliding rod 321, that is, the connecting member 35 slides in the horizontal direction and in the vertical direction simultaneously under the action of the sliding member 32, so that one end of the connecting member 35 is actually rotated in an arc.

The rotation control of the swing plate 311 is realized by the engagement of the slider 32 with the swing plate 311, and the swing direction of the swing plate 311 can be controlled more intuitively. In this embodiment, the connecting member 35 is pivotally connected to an end of the swing plate 311 away from the pivot portion 312. In order to more efficiently control the swing plate 311, the connecting member 35 is pivotally connected to an end of the swing plate 311 near the pivot portion 312. The arrangement thus constructed enables a large-sized swing of the swing plate 311 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 one end of the swinging plate 311 away from the pivoting portion 312, that is, the connecting member 35 is rotatably connected to the free end of the swinging plate 311, so that the arrangement of the structure can realize slower control of the connecting member 35, thereby realizing more precise adjustment of the temperature.

Further, in order to realize automatic temperature balance, that is, the swing direction of the air distributing member 31 in the air volume distribution module can be automatically controlled according to the specific temperatures of different compartments. In this embodiment, the pushing unit 33 is configured as a temperature-varying 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.

Specifically, as shown in fig. 3 or 7, the temperature varying structure includes a heated expansion member 331 that is matched with the air distribution member 31 and a temperature sensing member 332 for acquiring the temperature in the cooling compartment, the temperature sensing member 332 of the temperature varying structure is extended and disposed in the corresponding compartment, when the temperature in the compartment rises, the temperature sensing member 332 is heated, and at this time, the heated expansion member 331 expands and pushes the air distribution member 31 to swing in the direction of increasing the air output of the air outlet, wherein the air outlet is an air outlet entering the compartment.

After the temperature sensing element 332 is cooled, the heated expansion element 331 contracts in a direction away from the air distribution element 31, and drives the air distribution element 31 to move so as to reduce the air output of the air outlet, thereby reducing the supply of cooling capacity in the cooling compartment.

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

Specifically, the heated expansion member 331 includes an expansion shell having a working medium cavity, the temperature sensing member 332 is a temperature sensing tube communicated with the expansion shell, and the temperature sensing tube and the expansion shell are filled with a refrigeration working medium.
