Embodiments of the invention: as shown in fig. 1 to 11, a horizontal refrigerator is disclosed, which has a cabinet body 1 having a storage compartment 10, a refrigerating unit provided on the cabinet body 1, and a door body for opening or closing an opening of the storage compartment 10, the storage compartment 10 being provided to be opened upward. In this embodiment, the horizontal refrigerator is a direct-cooling type refrigerating device, that is, a direct-cooling mode is adopted to cool the articles stored in the storage compartment 10.
Specifically, the refrigerating unit includes a compressor, a condenser, a throttling device, and an evaporator, which are sequentially connected, the cabinet body 1 has an inner container 12 forming the storage compartment 10 and an outer shell 11 disposed outside the inner container 12, as shown in fig. 3, and the evaporator includes an evaporation tube 2 wound outside the inner container 12; the evaporation tube 2 transmits cold energy to the storage compartment 10 in a natural radiation manner and is used for refrigerating the articles stored in the storage compartment 10.
In the prior art, since the cooling capacity is transferred from the inner wall of the storage compartment 10 (i.e., the liner 12) to the middle position of the storage compartment 10, the size of the storage compartment 10 is generally larger, and the larger size inevitably causes uneven cooling capacity in the storage compartment 10. In particular, the more cold is present at a position closer to the inner wall of the storage compartment 10.
In addition, since the storage compartment 10 is disposed with the opening upwards, and the upper side of the whole storage compartment 10 is open, the cooling capacity at the position of the opening of the storage compartment 10 is seriously dissipated outwards, and the difference between the cooling capacity at the position of the storage compartment 10 close to the opening and the cooling capacity of the storage compartment 10 close to the bottom is also caused. The cooling capacity is more and more sufficient in the area near the bottom of the storage compartment 10, and the cooling capacity is relatively insufficient at the opening position of the storage compartment 10.
In this embodiment, in order to make the cooling capacity in the direct-cooling refrigeration device more uniform, the air duct module 3 is further disposed in the storage compartment, and the air duct module 3 is disposed in the storage compartment 10 and is used for transmitting the cooling capacity in a region with sufficient cooling capacity in the storage compartment to a region with insufficient cooling capacity.
As shown in fig. 4 to 7, the air duct module 3 includes an air inlet 31, an air outlet 32, an air duct 33, and a fan assembly 4, wherein the air inlet 31 and the air outlet 32 are communicated with the storage compartment 10, the air duct 33 is communicated with the air inlet 31 and the air outlet 32, and the fan assembly drives cold energy to flow from the air inlet 31 to the air outlet 32.

The arrangement of the fan assembly 4 can transmit the expected sufficient cooling capacity of the cooling capacity in the storage compartment 10 to the area with insufficient cooling capacity, so that the cooling capacity in the storage compartment 10 is more uniform.
In this embodiment, the air inlet 31 is disposed at a position near the bottom of the storage compartment 10, the air outlet 32 is disposed at a position near the opening of the storage compartment 10, and the air outlet 32 is disposed at a position near the opening of the storage compartment 10, so that the air outlet 32 is actually blown out toward a high temperature area in the storage compartment 10, that is, toward an area with insufficient cooling capacity in the storage compartment 10.
The air inlet 31 is disposed near the bottom of the storage compartment 10, and in fact, the air inlet 31 is disposed in a low temperature area of the storage compartment 10, that is, in an area where the cooling capacity is relatively sufficient.
The arrangement of the structure is to adopt the forced convection generated by the fan assembly 4 to transfer the cold energy at the bottom of the storage compartment 10 towards the opening of the storage compartment, thereby realizing the supplement of the cold energy in the cold energy sufficient area of the storage compartment 10 to the cold energy insufficient area.
The air outlets 32 are provided in plural and juxtaposed in the horizontal direction in the present embodiment; each air outlet 32 is communicated with the fan outlet 42 through an independent air outlet air duct 332, the air duct module 3 further has a damper assembly 34 disposed in the air outlet air duct 332, and a corresponding damper assembly 34 is disposed in each air outlet air duct 332.

It should be noted that different storage partitions may not be separated by a physical partition, but different objects are placed at different positions in the storage compartment 10 to form a storage partition, each storage partition is provided with a corresponding air outlet 32 corresponding to the storage partition, and the cooling capacity of the air outlet 32 is adjusted for the temperature of the corresponding storage partition.
In a specific embodiment, the cooling capacity of the area in the storage compartment 10 near the inner wall of the storage compartment is generally relatively sufficient, and the cooling capacity of the area in the middle of the storage compartment 10 in the width direction is relatively insufficient, so that different cooling capacity distributions exist in different areas in the storage compartment 10, and the embodiment can match the differences by arranging a plurality of air outlets along the width direction of the cabinet body 1, thereby better realizing the uniform temperature in the storage compartment 10.
As shown in fig. 2, in this embodiment, the housing 35 extends along the opening direction of the storage compartment 10 and divides the storage compartment 10 into a first compartment 101 and a second compartment 102 that are arranged in parallel in the length direction, and as shown in fig. 10-11, the air outlet 32 includes a plurality of first air outlets 321 that are arranged to open toward the first compartment 101 and a plurality of second air outlets 322 that are arranged to open toward the second compartment 102.

The air outlet duct 332 includes a first air outlet duct 333 and a second air outlet duct 334, and the first air outlet duct 333 is communicated with the first air outlet 321 and the fan outlet 42; the second air outlet duct 334 is communicated with the second air outlet 322 and the fan outlet 42, the first air outlet duct 333 is provided with a plurality of air outlets and corresponds to the first air outlet 321 one by one, and the second air outlet duct 334 is also provided with a plurality of air outlets and corresponds to the second air outlet 322 one by one.
The first air outlet duct 334 is used for conveying the cold energy from the fan outlet 42 into the first compartment 101, and the second air outlet duct 334 is used for conveying the cold energy from the fan outlet 42 into the second compartment 102.
As shown in fig. 10, in this embodiment, since a plurality of first air outlets 321 are provided, a plurality of corresponding first air outlet passages 333 are also provided. As shown in fig. 11, the second air outlet 322 is provided in plurality, and thus the second air outlet duct 334 is also provided in plurality.
As shown in fig. 15, in the present embodiment, the first air outlet duct 333 and the second air outlet duct 334 are juxtaposed in the longitudinal direction of the cabinet, and are separated by a partition.
In this embodiment, no matter the first air outlet 321 opened to the first compartment 101 or the second air outlet 322 opened to the second compartment 102 are provided with four air outlets 32 arranged on the casing 35 along the width direction of the cabinet body, the four air outlets 32 are divided into two edge air outlets located opposite to the edge and two middle air outlets located opposite to the middle; in the vertical direction, the fan assembly 4 is arranged at the lower sides of the two middle air outlets.
The cooling capacity of the area corresponding to the two middle air outlets is relatively insufficient, so that the fan assembly 4 is arranged in the area, the cooling capacity can be more concentrated and rapidly discharged from the air outlet at the middle position, and the cooling capacity is better supplied to the area with insufficient cooling capacity, so that the temperature equalization in the storage compartment 10 is better realized.
Correspondingly, the first air outlet passages 333 are also provided with four, the second air outlet passages 334 are also provided with four, and the two first air outlet passages 333 located at the middle position are closer to the position of the fan assembly 4, so that the cooling capacity can more efficiently flow out through the first air outlet passages 333 at the middle position.
