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 supplies air with a relatively low temperature, the temperature of the air with a relatively low temperature gradually increases in the process of flowing downwards, and when the air reaches a certain position, the air supply device is likely to lose the refrigerating effect due to the excessively high temperature, so that an air supply device can be arranged near the position, and the object positioned at 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.

Here, a foaming material (which plays a role of heat insulation) is generally provided between the liner 1 and the case, and thus, the second air supply passage 173B may be provided in the foaming material.

The third embodiment of the invention provides an air-cooled horizontal refrigerator, as shown in fig. 4A to 4C, which is different from the first embodiment in that: the liner 1 further includes a third liner wall 15 and a fourth liner wall 16 disposed opposite to each other, a third air blower 17C is disposed in the third liner wall 15, and a fourth air blower 17D is disposed in the fourth liner wall 16. Here, since the air blowing devices are provided in both the third and fourth liner walls, the articles stored in the vicinity of both the third and fourth liner walls can be cooled.

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

Preferably, as shown in fig. 4A, the first air supply device 17A includes a first set of air supply openings 171B and a second set of air supply openings 171C, and the first set of air supply openings 171B are located above the second set of air supply openings 171C. In actual use, when the first group of air outlets 171B send out air with a lower temperature, the temperature of the air with a lower temperature gradually increases during the downward flow, and when the air reaches a certain position, the air with a lower temperature may lose the cooling effect due to the excessively high temperature, so that the second group of air outlets 171C may be disposed near the position, and the articles located below the position may be cooled.

Preferably, as shown in fig. 4A, the first group of air supply openings 171B is located at the top of the first liner wall 13, and the second group of air supply openings 171C is located at the middle of the first liner wall 13.

Alternatively, as shown in fig. 4A, the first air supply passage 173A may also provide air with a lower temperature for the third air supply device 17C and the fourth air supply device 17D.

Optionally, the fan set 35 is located between the evaporator compartment 36 and the first liner wall 13 of the liner 1. The fan assembly 35 may include a housing assembly and a fan, the housing assembly filling in the gap between the evaporator compartment 36 and the first liner wall 13.

The fourth embodiment of the present invention provides an air-cooled horizontal refrigerator, as shown in fig. 5A to 5F, which differs from the air-cooled horizontal refrigerator in the second embodiment in that: the liner 1 further includes a third liner wall 15 and a fourth liner wall 16 disposed opposite to each other, a third air blower 17C is disposed in the third liner wall 15, and a fourth air blower 17D is disposed in the fourth liner wall 16. Here, the air blowing devices are provided in the four inner container walls, so that the articles located near 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 the higher temperature sent out easily makes the articles located on the upper layer of the accommodating space 11 cool, and it is understood that after the articles on the upper layer are cooled, the air may be heated up to become the air with the higher temperature, so that the articles on the lower layer are not easily cooled, and the air with the lower temperature sent out by the air supply device with the lower position can cool the articles on the lower layer. As shown in fig. 5A to 5F, the distance between the third air blowing device 17C and the bottom plate 12 is smaller than the distance between the fourth air blowing device 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 supply device 17A and the fourth air supply device 17D, and the second air supply duct 173B supplies air having a relatively low temperature to the second air supply device 17B and the third air supply device 17C.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.

The above list of detailed descriptions is only specific to practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
