Detailed Description

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

Embodiments of the utility model: as shown in fig. 1 to 7, a horizontal refrigerator is disclosed, which has a cabinet body 1 having a storage space 10, a refrigerating unit provided on the cabinet body 1, and a door body for opening or closing an opening of the storage space 10, the storage space 10 being provided to be opened upward. In this embodiment, the horizontal refrigerator is a direct-cooling horizontal refrigerator, that is, a direct-cooling mode is adopted to cool the articles stored in the storage space 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 11 forming the storage space 10, and a housing 12 disposed outside the inner container 11, as shown in fig. 3, and the evaporator includes an evaporation tube 2 wound outside the inner container 11; the evaporation tube transmits cold energy into the storage space 10 in a natural radiation manner and is used for refrigerating the articles stored in the storage space 10.

In the prior art, the cold energy is transferred from the inner wall of the storage space 10 (i.e. the liner 11) to the middle position of the storage space 10, and the size of the storage space 10 is generally larger, and the larger size inevitably causes uneven cold energy in the storage space 10. In particular, the more cold is present at a position closer to the inner wall of the storage space 10.

In addition, since the storage space 10 is disposed towards the upper opening, and the upper side of the whole storage space 10 is open, the cooling capacity of the storage space 10 at the position of the opening is seriously dissipated outwards, and the difference between the cooling capacity of the storage space 10 near the opening and the cooling capacity of the storage space 10 near the bottom is also caused. The cooling capacity is more sufficient in the area closer to the bottom of the storage space 10, and the cooling capacity is relatively insufficient in the opening position of the storage space 10.

In this embodiment, in order to make the cooling capacity in the direct-cooling horizontal refrigerator more uniform, 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 in a region with sufficient cooling capacity in the storage space to a region with insufficient cooling capacity.

According to the utility model, the temperature equalization modules 3 are fixedly supported on the two opposite inner walls in the storage space 10, and the cold quantity at the bottom of the storage space 10 is transferred to the opening position of the storage space 10 through the temperature equalization modules 3, so that the cold quantity is transferred in the storage space 10 from a relatively sufficient cold quantity area to a region with insufficient cold quantity, the uniformity of the temperature in the storage space 10 can be better realized, and the problem that the refrigeration generated by the cold quantity loss due to frequent opening of the storage space 10 cannot meet the requirement is solved.

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

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

The heat conduction unit with the structure is actually used for generating forced convection by adopting the fan assembly to enable the cold energy at the bottom of the storage space 10 to be transmitted towards the opening position of the storage space, so that the cold energy in the cold energy sufficient area is supplemented to the cold energy insufficient area.

In other embodiments, the heat conduction unit may also perform the transfer of the cold energy by other manners, such as using a heat conduction member to perform radiation convection, or by flowing the coolant between the bottom and the opening of the storage space 10, so as to perform the transfer of the cold energy.

The temperature equalizing module 3 is supported on two opposite inner walls of the storage space 10 in the present embodiment, and the housing 31 is extended 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 role of temperature equalizing, realize the partition of the storage space 10, and better meet the demands of users.

In addition, compare in the mode of fixing in storing space 10 bottom, support casing 31 on two inner walls of storing space 10 need not to visit the bottom of storing space 10 and install fixedly, not only more convenient operation and also can not occupy the space of more bottoms, and the stability after the installation is fixed is also higher.

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

In this embodiment, the cooling capacity at the bottom of the storage space 10 is transmitted to the opening position through the arrangement of the fan assembly, and the cooling capacity at the opening of the storage space 10 can be rapidly supplemented after the door body is opened, so that the cooling deficiency caused by the cooling capacity dissipation 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 arranged overhead. The gap part is arranged at the bottom of the fan assembly, so that the flow and convergence of ambient cooling capacity at the bottom of the fan assembly can be facilitated, and the cooling capacity can be better transferred from the bottom of the storage space 10 to the opening position of the storage space 10.

The base 316 is provided with a volute locating plate adapted to the volute 36, and the volute 36 is buckled on the volute locating plate.

Because the front side in the opening direction of the volute air inlet 361 needs to be provided with a gap between the front side direction of the volute air inlet 361 and the cover plate 317, in order to avoid the overall thickness of the casing 31 being larger, the base 316 is provided with an outwardly protruding fan mounting portion, the fan mounting portion is provided with a fan mounting groove arranged inwards, the opening of the fan mounting groove faces the cover plate 317, the arrangement of the mounting groove actually provides an avoidance, and the outwardly protruding fan mounting portion is increased only at the mounting position of the fan, so that the thickness of the whole casing 31 is prevented from being increased under the premise of meeting the fan mounting condition.

the communication hole 372 communicates the air outlet cavity with the air inlet cavity; the volute 36 is disposed at the position of the communication hole 372, the volute air outlet 362 is opposite to the position of the communication hole 372, the volute air inlet 361 is directly exposed to the air inlet cavity, the air inlet channel 351 is disposed in the air inlet cavity, and the air outlet channel 352 is disposed in the air outlet cavity or the air outlet cavity directly forms the air outlet channel 352.

Because the turbo fan 32 is used as a power source for transferring cold, the air outlet cavity and the air inlet cavity are relatively arranged at the upper side and the lower side of the communication hole 372 in the vertical direction for realizing high-efficiency transmission of cold.

In this embodiment, as shown in fig. 10, opposite sides of the air guiding body 371 are respectively fixed to the cover 317 and the base 316, and the air guiding body 371 is clamped and fixed between the cover 317 and the base 316.

In this embodiment, the air duct is actually formed by arranging the air guide 37 in the housing 31, and in order to better realize the transmission of the cold energy in the air duct, the air guide 37 is a foam member arranged between the cover plate 317 and the base 316.

The air guide piece 37 is arranged to be a foam piece, so that the air guide piece 37 can be attached to the base 316 and the cover plate 317 more tightly on the basis of reducing cost and weight, the foam piece can bear certain deformation, and the foam piece can be attached to the cover plate 317 or the base 316 only in a pressing mode.

In the prior art, the air deflector is generally integrally injection molded on the base 316, and one end of the air deflector far away from the base 316 is attached to the cover plate 317 to form an air channel between the air deflector, the cover plate 317 and the base 316. One end of the air deflector attached to the cover plate 317 in the prior art is difficult to be completely attached to the cover plate 317, so that a gap exists between the air deflector and the cover plate 317, and when cold is transferred in the air duct, the cold can leak out of the gap, thereby influencing the efficiency of cold transfer in the air duct.

According to the embodiment, the air guide piece 37 made of foam materials is clamped between the cover plate 317 and the base 316, so that two opposite sides of the air guide piece 37 can be attached to the cover plate 317 and the base 316, gaps are avoided between the air guide piece 37 and the cover plate 317 or between the air guide piece 37 and the base 316, leakage of cold energy cannot occur when the cold energy is transmitted in the air duct, and the cold energy can be more efficiently discharged from the air inlet and then the air outlet along the extending direction of the air duct.

In order to reduce the thickness of the entire housing 31, in this embodiment, the side of the volute 36 facing the base 316 is not provided with a cover plate, but directly uses the base 316, so that the base 316 forms a side wall enclosing a volute cavity, that is, an open slot is formed on the side of the volute 36 facing the base 316, and the base 316 is blocked at the opening position of the open slot to form the volute cavity.

As shown in fig. 13, the scroll casing 36 needs to be formed into the inner wall of the scroll casing cavity by the base 316, and the scroll casing 36 needs to be generally tightly attached to the base 316, but in the actual manufacturing process, a gap exists between the scroll casing 36 and the base 316, and the existence of the gap can cause the cold to leak out from the side of the air duct, so that the release efficiency of the cold of the air outlet 34 is reduced; and if a complete fit of the volute 36 to the base 316 is required, the difficulty of the machining process is high, and the cost is increased.

As shown in fig. 12 and 15-17, in order to reduce the lateral exposure of the cold energy during the transmission in the air duct, the air guide 37 further has a volute positioning portion 373 provided on the air guide body 371; the volute positioning portion 373 is fixedly attached to the base 316 and has a positioning groove 374 (shown in fig. 17) that is adapted to the volute 36, and the positioning groove 374 has an opening that is exposed toward the communication hole 372, that is, the positioning groove 374 communicates with the communication hole 372.

In this embodiment, the volute positioning portion 373 attached to the base 316 is provided outside the volute 36, so that the problem of leakage of cold energy caused by a gap between the volute 36 and the base 316 can be effectively solved.

In this embodiment, the volute positioning portion 373 and the air guiding body 371 are integrally formed and made of foam material, however, in other embodiments, a material with a certain deformation such as rubber may be used, so that the air guiding member 37 can be tightly attached to the cover plate 317 and the base 316 when clamped between the base 316 and the cover plate 317.
