Detailed Description

The present invention will be described in detail below with reference to the embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.

Terms such as "upper," "above," "lower," "below," and the like, as used herein, refer to a spatial relative position, and 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 term spatially relative position 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 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 objects should not be limited by these terms. These terms are only used to distinguish one such descriptive object from another. For example, a first liner wall may be referred to as a second liner wall, and similarly a second liner wall may also be referred to as a first liner wall, without departing from the scope of the present application.

The embodiment of the invention provides an air-cooled horizontal refrigerator, which is shown in fig. 1A, 1B and 2A-2C, and comprises the following components: the liner 1 comprises a bottom plate 12, a first liner wall 13 and a second liner wall 14 which are oppositely arranged; at least two groups of air supply openings are arranged in the first liner wall 13, wherein a first group of air supply openings 17A are arranged at the top of the first liner wall 13, and a second group of air supply openings 17B are arranged at the middle part of the first liner wall 13; at least two groups of air inlets are arranged in the second liner wall 14, wherein the distance between the first group of air inlets 18A and the bottom plate 12 is smaller than the distance between the first group of air inlets 17A and the bottom plate 12 and larger than the distance between the second group of air inlets 17B and the bottom plate 12, and the second group of air inlets 18B are arranged at the bottom of the second liner wall 14.

Here, the air blower 17 includes at least a first group of air outlets 17A and a second group of air outlets 17B, and the air suction device 18 includes at least a first group of air suction openings 18A and a second group of air suction openings 18B.

Here, in use, air with a low temperature is blown out from the first and second sets of air outlets into the accommodating space 11 (the accommodating space 11 surrounded by the inner liner 1), and the air with a low temperature flows from top to bottom and flows from the first inner liner wall 13 to the second inner liner wall 14, and during this process, the air flows through most of the articles in the accommodating space 11 with a high probability, and then flows out from the first and second sets of air outlets, so that it is possible to uniformly cool the articles stored in the accommodating space 11.

Here, in the air-cooled horizontal refrigerator according to the embodiment of the present invention, the air with the lower temperature sent by the first group of air outlets 17A flows downward along the direction from the first liner wall 13 to the second liner wall 14 from top to bottom, and is sucked away by the first group of air outlets 18A with a high probability, that is, the articles located on the upper layer of the accommodating space 11 are refrigerated; the air with lower temperature sent by the second set of air inlets 17B flows downwards along the direction from the first liner wall 13 to the second liner wall 14 from top to bottom, and there is a high probability that the air will be sucked away by the second set of air inlets 18B, i.e. the articles located at the lower layer of the accommodating space 11 will be refrigerated. So that the articles stored in the accommodating space 11 can be uniformly cooled.

Alternatively, two layers of food baskets may be placed in the accommodating space 11, and the first group of air inlets 17A is higher than the openings of the upper layer of food baskets, the first group of air inlets 18A is lower than the bottom of the upper layer of food baskets, the second group of air inlets 17B is higher than the openings of the lower layer of food baskets, and the second group of air inlets 18B is certainly lower than the bottom of the lower layer of food baskets.

Here, when the suction cover 182 closes the suction port 181 (e.g., the suction cover 182 covers the suction port 181), air cannot flow into the suction port 181, whereas when the suction cover 182 opens (e.g., the suction cover 182 does not cover the suction port 181), air can flow into the suction port 181

Alternatively, the air supply cover 172 can change the direction of the air blown by the air supply opening 171, and in practice, when there are more articles in a certain direction, the air can be blown into the direction by the air supply cover 172, so that the uniform refrigeration of the articles in the accommodating space 11 is facilitated.
