Detailed Description

The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

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.

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.

In this embodiment, for example, the perishable object to be stored may be seafood or vegetables, and the top-grade object to be stored may be ice cream with a relatively high unit price; the non-perishable object to be stored may be beer or beverage, and the low-grade object to be stored may be ice cream with relatively low price or ice cream with low melting tendency; the typical items to be stored for perishability may be pasta or meats, while the medium-grade store may be ice cream of relatively medium price.

If the storage of the to-be-stored object with high freezing grade occupies the storage partition, controlling the air door components of the occupied storage partition to be opened and closing the air door components of other storage partitions;

if no high freeze level storage of the to-be-stored object occupies the storage partition, the damper assembly of the intermediate storage partition 1002 is controlled to be opened.

In this embodiment, whether the storage partition occupied by the high-freezing-level storage object is the middle storage partition 1002 or the edge storage partition 1001, the high-freezing-level storage object is preferentially cooled when the high-freezing-level storage object is stored. If no frozen articles are stored, the air door assembly of the middle storage partition 1002 is controlled to be opened due to the relatively high temperature of the middle storage partition 1002, so that the uniform temperature can be better realized.

In another embodiment, before "if yes, controlling the damper assembly of the occupied storage partition to open" further includes the following steps:

If yes, the damper assembly of the intermediate storage partition 1002 is controlled to open.

In this embodiment, there are eight storage partitions, and if the storage partitions occupied by the high-freezing-level articles are more than four, the high-freezing-level articles are located in either the edge storage partition or the middle storage partition or both the edge storage partition and the middle storage partition. Therefore, the air door assembly of the middle storage partition 1002 is controlled to be opened to better control the temperature, and the edge storage partition 1001 is close to the inner wall of the horizontal refrigerator because the temperature of the inner wall of the horizontal refrigerator is lower, so that the sufficient cold energy supply of the area can be ensured even if the air door assembly is not opened.

In this embodiment, if the product with high freezing grade occupies more middle storage partitions, because the cooling capacity of the middle storage partition 1002 is insufficient, in order to realize concentrated cooling, two middle storage partitions 1002 need to be alternately cooled to better meet the requirement of the product with high freezing grade.

Only products of high and low freezing grades within the storage compartment are considered in the above several embodiments. In another embodiment, if the product with the low freezing grade is further disposed in the storage compartment, the following judging method is adopted, and before the step of controlling the opening of the air door assembly of the occupied storage partition if yes, the following steps are further included:

The embodiment ensures the cooling requirement of the high-freezing grade product and the freezing grade product in an implementation way, thereby realizing the control of the cooling capacity more efficiently.

Further, if there is no high-freezing-grade product in the storage compartment, the judgment and control are performed according to the quantity of the low-freezing-grade products and the quantity of the low-freezing-grade products. Specifically, if no high-freezing-level to-be-stored object occupies a storage partition, acquiring the number M of the storage partition occupied by the freezing-level to-be-stored object;

if N is less than four, controlling the opening of the air door assembly corresponding to the middle storage partition. When N is less than four, the number of storage partitions in the storage compartment to be emphasized is small, so that only the intermediate storage partition 1002 with insufficient cold energy supply needs to be started.

While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
