Specifically, the vertical plate 13 and the horizontal plate 14 form a boss protruding into the inner container 1, and a yielding cavity for yielding to the compressor is formed at the lower part of the boss.

The cooling space comprises a cooling chamber 4 formed by enclosing the horizontal plate 14 and the air duct cover plate 2, an air return duct 5 formed by enclosing the vertical plate 13, the bottom wall 11, the first side wall 12 and the air duct cover plate 2, and an air supply duct 6 formed by enclosing the second side wall 15 and the air duct cover plate 2, wherein the air return duct 5 and the air supply duct 6 are communicated with the cooling chamber 4. The transverse evaporator 3 is arranged in the cooling chamber 4.

Specifically, the wind channel cover plate 2 includes a first return air cover plate 21 matched with the first side wall 12, a second return air cover plate 22 connected to the bottom end of the first return air cover plate 21 and matched with the bottom wall 11, a third return air cover plate 23 connected to the second return air cover plate 22 and matched with the vertical plate 13, a horizontal portion 24 formed by the horizontal plate 14 in a surrounding manner, and a wind supply cover plate 25 formed by the second side wall 15 in a surrounding manner for the wind supply channel 6.

Further, the horizontal portion 24 is provided with a reinforcing structure to reinforce the strength of the horizontal portion 24 and enhance the load-bearing capacity of the horizontal portion 24, so that a user can place more heavy objects on the horizontal portion 24, and the universality of the storage space is enhanced.

Further, the reinforcing structure includes a reinforcing iron 7 provided on a lower side of the horizontal portion 24.

Specifically, a plurality of buckles 241 protruding downwards are arranged on the lower side of the horizontal portion 24, the plurality of buckles 241 are arranged in pairs to fix the reinforcing iron 7 on the lower side of the horizontal portion 24, and the buckles 241 and the air duct cover plate 2 can be integrally formed, so that the structure is simple and the cost is low. Of course, the invention is not limited thereto, and it is understood that in other embodiments, other connecting manners may be adopted to connect and fix the reinforcing iron 7.

Further, the reinforcing iron 7 extends in the front-rear direction to increase a supporting area, further enhancing the load-bearing capacity of the horizontal portion 24.

It can be understood that the length of the transverse evaporator 3 in the front-back direction is only required to be slightly smaller than the width of the storage space in the front-back direction, that is, the transverse evaporator 3 and the third and fourth side walls are only required to have an installation gap therebetween. Therefore, the length of the transverse evaporator 3 in the front-rear direction is generally greater than the length of the transverse evaporator 3 in the left-right direction, so as to improve the space utilization rate. The extending direction of the reinforcing iron 7 corresponds to the longer side of the horizontal evaporator 3, so that the supporting area of the reinforcing iron 7 can be increased, and the load-bearing capacity of the horizontal part 24 can be further enhanced.

Further, the reinforcing structure further includes a plurality of ribs 242 disposed at intervals, and the ribs 242 are integrally formed with the horizontal portion 24 to enhance the supporting strength of the horizontal portion 24.

Further, the refrigeration device 100 further comprises a heat insulation board 8 located between the horizontal evaporator 3 and the horizontal portion 24, and on one hand, the heat insulation board 8 isolates the cold energy of the horizontal evaporator 3 to prevent articles arranged on the horizontal portion 24 from being frozen; on the other hand, the heat insulation board 8 can enhance the load bearing capacity of the horizontal part 24 and reduce the influence of the articles on the horizontal part 24 on the horizontal evaporator 3.

Furthermore, the horizontal evaporator 3 comprises an evaporator body 31 and a mounting plate 32 arranged on the lower side of the evaporator body 31, a drain part 141 which is recessed downwards is arranged at the position of the horizontal plate 14 corresponding to the horizontal evaporator 3, the overlapping width of the edge of the mounting plate 32 and the drain part 141 is not less than 4mm, on one hand, the mounting plate 32 is connected to the evaporator body 31, and the strength of the horizontal evaporator 3 can be enhanced; on the other hand, the load-bearing capacity of the horizontal portion 24 can be indirectly enhanced by increasing the contact area between the mounting plate 32 and the horizontal plate 14.

It can be understood that an object is placed on the horizontal portion 24, the object transmits weight to the horizontal portion 24, after the horizontal portion 24 deforms, the heat insulation board 8 transmits weight to the horizontal evaporator 3, the horizontal evaporator 3 transmits the weight to the inner container 1 through the mounting plate 32, and therefore, by arranging the reinforcing structure, the contact area between the mounting plate 32 and the horizontal plate 14 is increased, the bearing capacity of the horizontal portion 24 can be improved, a user does not need to worry about the bearing problem of the horizontal portion 24, the use experience of the user is improved, and the utilization rate of the storage space is enhanced.

Furthermore, a position of the horizontal plate body corresponding to an end of the mounting plate 32 far away from the stopping protrusion 142 is convexly provided with a limiting block 144, that is, after the mounting plate 32 is mounted on the horizontal plate 14, an end of the mounting plate 32 far away from the stopping protrusion 142 abuts against the limiting block 144, so as to limit the mounting seat from moving to the end far away from the stopping protrusion 142 in a dislocation manner.

It can be understood that one end of the mounting plate 32 overlaps the arc-shaped section 143, and the other end abuts against the limiting block 144, so as to limit the horizontal evaporator 3 and prevent the horizontal evaporator 3 from moving left and right.

Furthermore, at least one first air return opening 231 is arranged on the third air return cover plate 23, and at least one first air return opening 231 is higher than the stopping protrusion 142, so that the direction of the return air entering the return air duct 5 from the second air return opening 211 can be changed by the return air entering the return air duct 5 from the first air return opening 231, most of the return air in the return air duct 5 can horizontally enter the cooling chamber 4 and horizontally flow through the transverse evaporator 3, and the heat exchange efficiency is improved.

Further, the horizontal evaporator 3 further includes an upper clamp plate 33 provided on the upper side of the evaporator body 31, so that the strength of the horizontal evaporator 3 can be enhanced, and the load-bearing capacity of the horizontal portion 24 can be further enhanced.

Specifically, the part of the upper clamp plate 33 close to the air return duct 5 is provided with an air return grille 331, one side of the heat preservation plate 8 close to the air return duct 5 is provided with an air guide cambered surface 81, and part of the air guide cambered surface 81 corresponds to the air return grille 331, so that the return air of the air return duct 5 can be guided to enter the evaporator body 31 through the air guide cambered surface 81 to exchange heat, and the heat exchange efficiency is enhanced.

Further, the horizontal evaporator 3 further includes heater strips 34 provided at the upper end and the lower end of the evaporator body 31, and the defrosting effect can be enhanced by integrally providing the heater strips 34 on the evaporator body 31.
