Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

Terms such as "upper," "above," "lower," "below," and the like, used herein to denote relative spatial positions, are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Also, it should be understood that, although the terms first, second, etc. may be used herein to describe various elements or structures, these described elements should not be limited by these terms. These terms are only used to distinguish these descriptive objects from one another. For example, the first inner container wall may be referred to as the second inner container wall, and similarly the second inner container wall may also be referred to as the first inner container wall, without departing from the scope of the present application.

In one embodiment of the present invention, an air-cooled horizontal refrigerator is provided, and it is first stated that the air suction hole 181 in fig. 2C is not shown in fig. 1, and the air supply hole 171 in fig. 2A is also not shown in fig. 1. As shown in fig. 1 and fig. 2A to 2C, includes: the inner container 1 comprises a bottom plate 12 and a plurality of inner container walls, a partition plate 3 is connected to the upper side of the bottom plate 12, the partition plate 3 divides an inner space enclosed by the inner container 1 into an evaporator chamber 36 and an accommodating space 11, and an evaporator 32 and a fan set 35 are arranged in the evaporator chamber 36;

an air supply device 17 used for supplying air to the accommodating space 11 is arranged in the inner container wall, an air suction device 18 used for sucking air from the accommodating space 11 is arranged on a first cover plate 33 in the partition plate 3, the air suction device 18 is communicated with the evaporator chamber 36, and the first cover plate 33 is connected with the bottom plate 12.

Here, the internal space is a space surrounded by the bottom plate 12 and the plurality of inner container walls, and as shown in fig. 1, the bottom of the inner container 1 is recessed toward the internal space to form the recess 2, and the internal space should not include the recess 2. In practice, it is usually necessary to partition an evaporator compartment 36 on the upper side of the bottom plate 12 for installing an evaporator, etc., and it is understood that a corner (i.e., the corner formed between the first cover plate 33 and the bottom plate 12) is formed between the evaporator compartment 36 and the bottom plate 12, and the articles stored in the corner are not easily cooled, whereas in the air-cooled horizontal refrigerator in the embodiment of the present invention, the articles stored in the corner are easily cooled by disposing the air suction device 18 on the first cover plate 33.

Here, during cooling, the air with higher temperature in the accommodating space 11 is sucked by the suction device 18 and then flows into the evaporator compartment 36, and in the evaporator compartment 36, the air with lower temperature is obtained due to cooling of the evaporator 32, and then the air with lower temperature flows into the air blowing device 17 and is sent into the accommodating space 11, thereby completing cooling of the accommodating space 11. In this process, the fan unit 35 will operate to power the flow of air.

Preferably, as shown in fig. 2C, the air suction device 18 is disposed at the bottom of the first cover plate 33. Here, since the suction device 18 is disposed at the bottom of the first cover plate 33, the articles stored in the corner formed by the first cover plate 33 and the bottom plate 12 are more easily cooled, thereby facilitating the uniform cooling of the articles in the accommodating space 11.

Preferably, as shown in fig. 2C, the air suction device 18 includes a plurality of air suction holes 181 which are horizontally and uniformly arranged. Here, the air suction holes 181 are horizontally and uniformly arranged, and the stored goods can be cooled in each portion of the corner in the direction of the intersection line of the first cover plate 33 and the bottom plate 12 (as shown by the double-headed solid arrow in fig. 2C).

Preferably, as shown in fig. 2C, the height values of the plurality of air suction holes 181 are not all equal. Here, the height value of the air suction hole 181 means a dimension of the air suction hole in a vertical direction, and the air suction hole 181 may have various shapes such as a circle, a square, and the like, for example, in fig. 2C, the air suction hole 181 has a square shape. Here, the height values of the air suction holes 181 are not all equal, that is, the height values of some air suction holes 181 are not equal, or the height values of some air suction holes 181 are equal, for example, in fig. 2C, the air suction device 18 includes 6 air suction holes 181 uniformly arranged in the horizontal direction, and in the direction of the first inner container wall 13 toward the second inner container wall 14, the first and second air suction holes are a first group of air suction holes, the third and fourth air suction holes are a second group of air suction holes, the fifth and sixth air suction holes are a third group of air suction holes, the height values of two air suction holes in each group of air suction holes are equal, and the height value of the first group of air suction holes is greater than that of the second group of air suction holes, and the height value of the second group of air suction holes is greater than that of the third group of air suction holes. Here, since the height values of the air suction holes 181 are not all the same, it can be understood that, in practical use, a user usually prefers to stack articles on the bottom plate 12, if the number of stacked articles is too large, the air suction holes 181 with a low height value are easily blocked, and in the air-cooled horizontal refrigerator according to the embodiment of the present invention, air can be sucked from the air suction holes 181 with a high height value; however, if the height values of the air suction holes 181 are set high, that is, the size of the air suction holes 181 becomes large, foreign substances are easily introduced into the evaporator compartment 36 along the air suction holes 181.
