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 refrigeration 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.

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.

When the air-cooled evaporator is arranged in the air duct module 3, the horizontal refrigerator is cooled by adopting a mode of air cooling and direct cooling.

Because the air duct module 3 of the present application divides the storage compartment 10 into the first compartment 101 and the second compartment 102, in order to better realize the uniformity of the temperatures of the first compartment 101 and the second compartment 102, another embodiment of the present application also discloses a temperature control method of a horizontal refrigerator,

The method specifically comprises the following steps:

Acquiring a temperature T1 in the first compartment 101 and a temperature T2 in the second compartment 102; wherein the first compartment 101 and the second compartment 102 are separated by the air duct module 3 in the storage compartment 10;

Judging whether the temperature T1 in the first compartment 101 is greater than the temperature T2 in the second compartment 102; determining if the temperature difference Δt1=t1-T2 between the first compartment 101 temperature T1 and the second compartment 102 temperature T2 exceeds a first threshold T1 when T1 is greater than T2;

After the delta T1 exceeds the first threshold T1, judging whether the delta T1 exceeds a second threshold T2, wherein the second threshold T2 is larger than the first threshold T1;

If Δt1 is greater than the second threshold T2, the first damper 341 is controlled to be opened, and the second damper 342 is controlled to be closed; the first air door 341 is used for controlling the on or off of the first air outlet air duct 333 communicated with the first compartment 101, the second air door 342 is used for controlling the on or off of the second air outlet air duct 334 communicated with the second compartment 102, and the first air outlet air duct 333 and the second air outlet air duct 334 are both arranged on the air duct module 3;

After Δt1 exceeds the first threshold T1, it indicates that the temperature in the first chamber 101 is significantly higher than the temperature in the second chamber 102, so, in order to more efficiently achieve the uniformity of the temperature in the first chamber 101 and the temperature in the second chamber 102, the second air outlet duct 334 for cooling the second chamber 102 may be closed first, so that the cooling capacity is released into the first chamber 101 through the first air outlet duct 333.

If Δt1 is greater than T1 but less than T2, the opening angle of the first damper 341 is controlled to be greater than the opening angle of the second damper 342.

If Δt1 is greater than T1 but less than T2, it indicates that the temperature in the first chamber 101 is higher than the temperature in the second chamber 102, but the difference in temperature between them is not so large, so that the passage of the cold into the first chamber 101 is opened more than the passage of the cold into the second chamber 102, and the homogenization of the temperatures of the first chamber 101 and the second chamber 102 can be achieved.

It should be noted that the opening angle of the first air door 341 and the second air door 342 determines the efficiency of the cold air flowing out of the corresponding air outlet duct, and it can be understood that when the opening angle of the air door is larger, the higher the efficiency of the cold air flowing out of the corresponding air outlet duct, the faster the temperature of the compartment communicated with the air outlet duct is cooled.

According to the embodiment, the opening angles of the first air door 341 and the second air door 342 can be timely adjusted through the temperature difference between the first compartment 101 and the second compartment 102, so that the distribution of the cold energy entering from the air inlet 31 between the first air outlet 321 and the second air outlet 322 is adjusted, and further the uniform temperature adjustment in the storage compartment 10 can be better realized.

In this embodiment, "controlling the opening angle of the first damper 341 to be larger than the opening angle of the second damper 342" specifically includes:

The first damper 341 is controlled to be fully opened while the second damper 342 is controlled to be half opened. When the first air door 341 is completely opened, the first air door 341 does not cover the first air outlet duct 333, so that the cooling capacity can flow from the first air outlet duct 333 more smoothly.

The second damper 342 may be opened half way, or the second damper 242 may cover the air duct in a normal manner, and in any case, the second damper 342 may block or cover a part of the air duct on a plane perpendicular to the air duct. The above arrangement of the second damper 342 may affect the flow efficiency of the cooling capacity in the second outlet air duct 334, thereby affecting the efficiency of cooling the second compartment 102.

Further, "acquiring the temperature T1 in the first chamber 101 and the temperature T2 in the second chamber 102" specifically adopts the following manner:

acquiring the temperature in the first compartment 101 through a first temperature sensor, wherein the first temperature sensor is arranged on the door body, and the first temperature sensor is positioned right above the central position of the first compartment 101 after the door body is closed;
