Detailed Description

The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

The embodiment of the invention comprises the following steps: as shown in fig. 1 to 7, a horizontal refrigerator is disclosed, which comprises a cabinet body 1 having a storage space 10, a refrigerating unit disposed on the cabinet body 1, and a door body for opening or closing an opening of the storage space 10, wherein the storage space 10 is disposed to be opened upward. In this embodiment, the horizontal refrigerator is a direct-cooling horizontal refrigerator, that is, the direct cooling mode is adopted to cool the articles stored in the storage space 10.

Specifically, the refrigerating unit comprises a compressor, a condenser, a throttling device and an evaporator which are connected in sequence, the cabinet body 1 is provided with an inner container 11 forming the storage space 10 and a shell 12 arranged outside the inner container 11, and as shown in fig. 3, the evaporator comprises an evaporation tube 2 wound outside the inner container 11; the evaporator tube transmits cold energy into the storage space 10 in a natural radiation mode and is used for refrigerating articles stored in the storage space 10.

In the prior art, because the cold energy is transferred from the inner wall (i.e. the inner container 11) of the storage space 10 to the middle position of the storage space 10, the size of the storage space 10 is generally large, and the large size inevitably causes the unevenness of the cold energy in the storage space 10. The more the cold is near the inner wall of the storage space 10, the more the cold is.

In addition, because the storage space 10 is arranged with an upward opening, and the upper side of the whole storage space 10 is an opening, the cold quantity at the opening position of the storage space 10 is seriously dissipated outwards, and the difference between the cold quantity at the position of the storage space 10 close to the opening and the cold quantity at the bottom of the storage space 10 is also caused. The specific expression is that the cold quantity is more sufficient in the area closer to the bottom of the storage space 10, and the cold quantity is relatively insufficient at the opening position of the storage space 10.

In order to make the cooling capacity in the direct-cooling horizontal refrigerator more uniform in this embodiment, a temperature equalizing module 3 is further disposed in the storage space, and the temperature equalizing module 3 is disposed on two opposite inner walls of the storage space 10 and is used for transmitting the cooling capacity of a region with sufficient cooling capacity in the storage space to a region with insufficient cooling capacity.

The temperature equalizing module 3 is provided with a shell 31 positioned in the storage space 10 and a heat conduction unit arranged in the shell, and the heat conduction unit is used for transmitting the cold energy at the bottom position of the storage space 10 to the opening position of the storage space 10.

Meanwhile, the temperature in the storage space 10 is more uniform due to the arrangement of the temperature equalizing module 3, so that the start-stop frequency of the press can be better reduced, and the effect of reducing energy consumption is achieved. In the embodiment, the cold quantity in the region with the sufficient cold quantity in the storage space 10 is actually supplied to the region with the insufficient cold quantity, so that the cold insulation time in the storage space 10 is prolonged, the starting frequency of the press can be indirectly influenced, the consumption of electric energy is reduced, and better energy conservation and emission reduction are realized.

In this embodiment, the temperature equalizing module further includes an air inlet 33, an air outlet 34 and an air duct 35 disposed on the housing 31 and communicating the air inlet 33 and the air outlet 34, and the heat conduction unit includes a fan assembly for driving cold energy to flow from the air inlet 33 to the air outlet 34; the fan assembly may be disposed within the air chute 35, it being understood that the fan assembly includes a fan.

The heat conduction unit with the structure actually adopts the fan component to generate forced convection to transmit the cold quantity at the bottom of the storage space 10 to the opening position of the storage space, so that the cold quantity in the region with sufficient cold quantity is supplied to the region with insufficient cold quantity.

In other embodiments, the heat conduction unit can also transmit the cold energy by other methods, such as transmitting the cold energy by radiation convection of the heat conduction member, or transmitting the cold energy by flowing coolant between the bottom and the opening of the storage space 10.

The present embodiment supports the temperature equalizing module 3 on two opposite inner walls of the storage space 10, and the housing 31 extends along the opening direction of the storage space 10 to divide the storage space 10 into a first compartment 101 and a second compartment 102. The temperature equalizing module 3 can realize the separation of the space in the storage space 10 while playing the temperature equalizing function, so that the storage space 10 is partitioned, and the requirements of users are better met.

In an embodiment, a gap 100 is formed between the bottom of the housing 31 and the bottom of the storage space 10.

In this embodiment, the cold quantity at the bottom of the storage space 10 is conveyed to the opening position through the arrangement of the fan assembly, the cold quantity at the opening of the storage space 10 can be rapidly supplemented after the door body is opened, and the insufficient cold supply caused by the loss of the cold quantity at the opening of the storage space can be avoided. Meanwhile, since the gap portion 100 is provided between the temperature equalizing module 3 and the bottom of the storage space 10, the temperature equalizing module 3 is actually provided in an overhead manner. Set up clearance portion can be convenient for around cold volume flow and assemble in fan subassembly bottom to better messenger's cold volume is from the bottom of storing space 10 to the open position transmission of storing space 10.
