Detailed Description

For the purpose of illustrating the technical content, the constructional features, the achieved objects and the effects of the invention in detail, reference will be made to the following detailed description of the embodiments in conjunction with the accompanying drawings.

Referring to fig. 1, a chest cooler 100 according to the present invention is shown. The chest freezer 100 includes a foamed chest body 1, and an upward opening door (the upward opening door is not shown) located at the top of the chest body 1. The horizontal cabinet 1 has a low temperature chamber 11 therein. Each side wall of the horizontal cabinet body 1 is made of an inner shell body, an outer shell body and a heat-preservation foaming filling material which is filled between the inner shell body and the outer shell body in a foaming way. The upward opening door is to openably cover the upper side of the horizontal type cabinet 1 and to shield the low temperature compartment 11. For the purpose of description with respect to the drawings, the up, down, left, right, front, and rear positional relationship described in the present embodiment corresponds to the positional relationship of the refrigerator shown in fig. 1, i.e., is defined in a view of a user standing on the front side of the chest freezer 100 facing the chest freezer 100.

As shown in fig. 2, 3 and 4, the horizontal cabinet 1 in this embodiment has a rectangular parallelepiped shape, and includes a left side wall 12, a right side wall 13, a front side wall 14, a rear side wall 15 and a bottom wall 16. The chest freezer 100 also includes a refrigeration system 3 and a wind circulation system. The refrigerating system 3 is used for providing cold energy for the low-temperature chamber 11, and the wind circulating system is arranged inside the horizontal cabinet body 1. The wind circulation system includes a wind tunnel plate assembly 41 and a rear inclined centrifugal fan 42 provided in the low temperature chamber 11.

As shown in fig. 4, the bottom wall 16 of the horizontal cabinet 1 of this embodiment is composed of a horizontal section 161 and a step section 162; the inner wall surface of the step section 162 includes a vertical step surface 1621 extending in the vertical direction and a horizontal step surface 1622 extending in the left-right direction.

As shown in fig. 1, 2 and 4, the refrigeration system 3 includes a compressor 31, a condenser 32, an evaporator 33 and a capillary tube (not shown). Wherein the compressor 31 and the condenser 32 are mounted outside the horizontal cabinet 1 and below the bottom wall stage 162.

As shown in fig. 5, the duct board assembly 41 includes a plurality of duct boards, i.e., a left duct board 411, a horizontal duct board 412, a stepped duct board 413, and a right duct board 414, which are installed to extend from left to right of the inner wall surface of the horizontal cabinet 1 and define a circulation duct 418 with the inner wall surface of a part of the horizontal cabinet 1.

As shown in fig. 4 and 5. The left air duct plate 411 is mounted on the left side wall of the horizontal type cabinet 1, and the horizontal air duct plate 412 and the stepped air duct plate 413 are mounted at the horizontal section 161 and the stepped section 162 of the bottom wall 16, respectively. The lower portion of the left air duct plate 411 is overlapped with the left end portion of the horizontal air duct plate 412, and the top portion of the left air duct plate 411 is provided with an air return opening 417. The stepped air passage plate 413 includes a vertical plate 4131 and a horizontal plate 4132, the vertical plate 4131 is located inside the vertical step surface 1621 and has a lower end overlapping the right end of the horizontal air passage plate 412, and the horizontal plate 4132 is located inside the horizontal step surface 1622. The right air duct plate 414 has a two-stage stepped structure, and includes a lower vertical plate 4141, a lower horizontal plate 4142, an upper vertical plate 4143, and an upper horizontal plate 4144, which are sequentially disposed. Wherein, the lower vertical plate 4141 is located at the right side of the vertical plate 4131, a gap is formed between the two, the gap forms a part of the circulating air duct 418, and a through hole 41411 is arranged on the lower vertical plate 4141; the lower horizontal plate 4141 is positioned at the right side of the horizontal plate 4132 and is mutually overlapped, and the two are locked by a plurality of screws after being overlapped; the upper vertical plate 4143 is provided with a narrow air supply opening 415 to the cooling compartment 11. In this example, the position of the blowing port 415 is higher than the position of the return air port 417. A housing 416 is provided below the right air duct plate 414 and on the right side of the lower vertical plate 4141.

As shown in fig. 6, the housing 416 includes a first housing 4161 and a second housing 4162, the housing 416 defining a chamber 4163 therein. The back-tipping centrifugal fan 42 is mounted within this chamber 4163. The first housing 4161 starts with an inlet 41611 in the middle and the second housing 4162 is provided with an outlet 41621 at the top.

As further shown in fig. 4 and 5, the evaporator 33 is mounted between the lower vertical plate 414 and the first housing 4161. Thus, the evaporator 33 and the backward inclined centrifugal fan 42 will realize a circulation duct 418 which is installed inside the horizontal step surface 1622 of the bottom wall 16 and is defined inside, with the inlet 41611 facing the evaporator 33 and the backward inclined centrifugal fan 42 and the evaporator 33.

When the horizontal refrigerator works, after the air flow passing through the commodities enters the circulating air duct 418 from the air return opening 417, the air flow firstly flows downwards from between the left side wall 12 and the left side air duct plate 411, then passes through the inner side of the horizontal air duct plate 412, then flows upwards to the gap between the lower vertical plate 4141 and the vertical plate 4131, enters the evaporator 33 from the through opening 41411 to flow rightwards, the air flow is absorbed by the evaporator 33 to become cold air flow, then the cold air flow is sucked into the chamber 4163 from the inlet 41611 of the first housing 4161 by the backward tilting centrifugal fan 42, and then under the action of the backward tilting centrifugal fan 412, the cold air flow escapes through the outlet 41621 at the top of the second housing 4162 and finally is sent into the low-temperature chamber 11 from the air supply opening 415. After the cold air flows through the commercial products in the low temperature chamber 11, most of the cold air enters the circulating air duct 418 again through the air return port 4111, and is cooled by the evaporator 33 while flowing along the circulating air duct 418, and then is sent into the low temperature chamber 11 again by the backward inclined centrifugal fan 42.

In other embodiments, the air duct board assembly may be assembled on the inner wall surface of the horizontal cabinet body by various other mounting methods such as clamping, riveting, and the like, and the mounting positions of the components such as the backward tilting centrifugal fan, the evaporator, and the like may also be adjusted appropriately.

Therefore, in the scheme, on one hand, the manufacturing cost of the horizontal refrigerator with the structure is lower; on the other hand, the backward inclined centrifugal fan has large air supply volume, so that the air flow circularly flowing in the circulating air duct can better meet the low-temperature storage requirement of the low-temperature chamber.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
