The bottom of the inner container 1 is recessed towards the accommodating space 11 to form a recess 2, the recess 2 has a first side wall 21, one end of the first side wall 21 is connected to the bottom plate 12 of the inner container 1, or the first side wall 21 extends from the bottom plate 12 towards the accommodating space 11; the air duct plate 3 is arranged adjacent to the first side wall 21, and a space between the air duct plate 3 and the first side wall 21 forms an evaporator chamber 36, and the evaporator 32 is arranged in the evaporator chamber 36; wherein, the air duct plate 3 is located in the accommodating space 11. The recess 2 further comprises a second side wall 22, the second side wall 22 is perpendicular to the first side wall 21, i.e. the first side wall 21 and the second side wall 22 form a right-angled structure, preferably, the first side wall 21 is perpendicular to the bottom plate 12, for example, one end of the first side wall 21 is perpendicular to the edge of the bottom plate 12; the second side wall 22 is perpendicular to the third inner container wall 15 of the inner container 1, and one end of the second side wall 22 is vertically connected with the lower edge of the third inner container wall 15. In this embodiment, the recess 2 may be regarded as a right-angled step structure formed by bending the bottom plate 12 toward the accommodating space 11, but not limited thereto. During production, the first sidewall 21 of the concave portion 2 may be bent from the bottom plate 12 toward the accommodating space 11, and the second sidewall 22 may be bent from the third liner wall 15 toward the accommodating space 11, such that the first sidewall 21 and the second sidewall 22 meet and are connected to each other in the accommodating space 11.

Alternatively, each of the air blowing ports 171 may be provided with an air blowing cover (not shown) that can open and close the air blowing port 171, and the air blowing cover may change the air blowing direction, and here, when the air blowing port 171 is covered by the air blowing cover, the air blowing port 171 cannot blow air at a low temperature, and conversely, when the air blowing port 171 is not covered by the air blowing cover, the air blowing port 171 can blow air at a low temperature. Here, as shown in fig. 2A, the shapes of the air blowing ports 171 may be uniform.

Preferably, as shown in fig. 2C, the air suction device 18 includes a plurality of air suction holes 181. Optionally, an air suction cover plate (not shown) may be disposed on the air suction hole 181, when the air suction cover plate covers the air suction hole 181, the air suction hole 181 cannot suck the air with higher temperature from the accommodating space 11, otherwise, when the air suction cover plate does not cover the air suction hole 181, the air suction hole 181 can suck the air with higher temperature from the accommodating space 11.

Optionally, as shown in fig. 2C, the sizes of the plurality of air suction holes 181 are not all the same. Here, as shown in fig. 2C, the air suction holes 181 may be all square, and if the direction in which the fourth inner container wall 16 points toward the third inner container wall 15 is a width direction and the direction in which the second inner container wall 14 points toward the first inner container wall 13 is a length direction, the width values of the air suction holes 181 are equal, but the height values may not be equal.

Here, as shown in fig. 2A to 2C, a water receiving box 37 is provided in the evaporator chamber 36, the water receiving box 37 is located below the evaporator 32, when defrosting the evaporator 32, ice and/or water obtained by melting frost on the surface of the evaporator 32 flows into the water receiving box 37, and an outlet of the water receiving box 37 is communicated with the water receiving pipe 25; the recess 2 may be a press chamber provided with a compressor 23, in which an evaporation pan 24 is provided, and the other end of the water receiving pipe 25 is provided directly above the evaporation pan 24, so that ice and/or water in the water receiving box 37 flows into the evaporation pan 24 along the water receiving pipe 25, the evaporation pan 24 can evaporate the ice and/or water using heat generated by the compressor 23 during operation, and a through hole communicating with an external space may be further provided in a chamber wall of the press chamber, so that water vapor obtained by evaporating the ice and/or water may flow into the external space along the through hole.

An embodiment of the present invention provides an air-cooled horizontal refrigerator, as shown in fig. 3A to 3D, which is different from the air-cooled horizontal refrigerator in the embodiment one in that: the liner 1 further comprises a second liner wall 14 arranged opposite to the first liner wall 13, and a second air supply device 17B is arranged in the second liner wall 14. Here, the second air blowing device 17B also sends out air having a low temperature, and the articles located near the second air blowing device 17B are also cooled.

Preferably, the distance between the first air blowing device 17A and the bottom plate 12 is not equal to the distance between the second air blowing device 17B and the bottom plate 12. In actual use, when the air supply device with a relatively high distance from the bottom plate 12 sends air with a relatively low temperature, the temperature of the air with a relatively low temperature gradually rises in the process of flowing downwards, and the air with a relatively low temperature possibly loses the refrigeration effect due to the excessively high temperature when reaching a certain position, so that one air supply device can be arranged near the position, and articles on the lower side of the position can be refrigerated. In fig. 3A to 3D, the distance between the first air blowing device 17A and the bottom plate 12 is larger than the distance between the second air blowing device 17B and the bottom plate 12.

Alternatively, as shown in fig. 3A, 3B and 3D, in the drawings, the channels indicated by the broken lines are air supply channels, a second air supply channel 173B is provided in the second liner wall 14, one end of the second air supply channel 173B is communicated with the second air supply device 17B, and the other end is communicated with the inter-evaporator chamber 36, so that air with a low temperature in the inter-evaporator chamber 36 can flow into the second air supply device 17B through the second air supply channel 173B under the driving of the fan set 35. Here, a foaming material (which plays a role of heat insulation) is generally provided between the inner bag 1 and the outer case, and therefore, the second air blowing passage 173B may be provided in the foaming material.

An embodiment of the present invention provides an air-cooled horizontal refrigerator, as shown in fig. 4A to 4C, which is different from the air-cooled horizontal refrigerator in the embodiment one in that: the liner 1 further comprises a third liner wall 15 and a fourth liner wall 16 which are oppositely arranged, a third air supply device 17C is arranged in the third liner wall 15, and a fourth air supply device 17D is arranged in the fourth liner wall 16. Here, since the air blowing devices are provided in both the third and fourth inner container walls, the articles stored in the vicinity of the third and fourth inner container walls can be cooled.

Alternatively, as shown in fig. 4A, the distance between the third air blowing devices 17C and the bottom plate 12 is equal to the distance between the fourth air blowing devices 17D and the bottom plate 12. Here, in fig. 4A, the first air blowing devices 17A, the third air blowing devices 17C and the fourth air blowing devices 17D are all equal in distance from the bottom plate 12, that is, the first, third and fourth air blowing devices may all be located at the top of the inner container wall.

Preferably, as shown in fig. 4A, the first blowing device 17A includes a first group of blowing ports 171B and a second group of blowing ports 171C, and the first group of blowing ports 171B is located above the second group of blowing ports 171C. In actual use, when the first group of air blowing ports 171B blows air with a low temperature, the temperature of the air with a low temperature gradually increases while the air flows downward, and there is a high possibility that the cooling effect is lost due to an excessively high temperature when a certain position is reached, and therefore, the second group of air blowing ports 171C may be provided in the vicinity of the position, so that articles located at the lower side of the position may be cooled.

Preferably, as shown in fig. 4A, the first group of air blowing ports 171B is located at the top of the first inner container wall 13, and the second group of air blowing ports 171C is located at the middle of the first inner container wall 13.

Alternatively, as shown in fig. 4A, the first air blowing passage 173A may supply air having a relatively low temperature to the third air blowing device 17C and the fourth air blowing device 17D.

Optionally, the fan unit 35 is located between the evaporator compartment 36 and the first inner container wall 13 of the inner container 1. The fan unit 35 may include a housing assembly that fills the gap between the evaporator compartment 36 and the first inner container wall 13, and a fan.

An embodiment of the present invention provides an air-cooled horizontal refrigerator, as shown in fig. 5A to 5F, which is different from the air-cooled horizontal refrigerator in the embodiment two in that: the liner 1 further comprises a third liner wall 15 and a fourth liner wall 16 which are oppositely arranged, a third air supply device 17C is arranged in the third liner wall 15, and a fourth air supply device 17D is arranged in the fourth liner wall 16. Here, the air blowing devices are provided in all of the four inner container walls, so that the articles located in the vicinity of all of the four inner container walls can be easily cooled.

Preferably, the distance between the third air blowing device 17C and the bottom plate 12 is not equal to the distance between the fourth air blowing device 17D and the bottom plate 12. Here, the air with a relatively high temperature sent out is easy to refrigerate the articles on the upper layer of the accommodating space 11, and it can be understood that after the articles on the upper layer are refrigerated, the air is heated up and may become air with a relatively high temperature, so that the articles on the lower layer are not easy to refrigerate, and the air with a relatively low temperature sent out by the air supply device with a relatively low position can refrigerate the articles on the lower layer. As shown in fig. 5A to 5F, the distance between the third air blowing devices 17C and the bottom plate 12 is smaller than the distance between the fourth air blowing devices 17D and the bottom plate 12.

Preferably, the distance between the first air blowing device 17A and the bottom plate 12 is equal to the distance between the fourth air blowing device 17D and the bottom plate 12, and the distance between the second air blowing device 17B and the bottom plate 12 is equal to the distance between the third air blowing device 17C and the bottom plate 12. Here, the first air supply duct 173A supplies air having a relatively low temperature to the first air blowing device 17A and the fourth air blowing device 17D, and the second air supply duct 173B supplies air having a relatively low temperature to the second air blowing device 17B and the third air blowing device 17C.
