Description

Technical Field

[0001] The present invention relates to a refrigeration device. Background Art

[0002] Existing refrigeration devices usually adopt air-cooling to improve refrigeration efficiency. Moreover, as the storage needs of users gradually increase, the capacity of refrigerators is getting larger and larger. Usually, more compartments are set up to meet the needs. Generally, the refrigerating compartment is located above the freezing compartment, while the compressor compartment and the refrigerating chamber are usually located on the lower side of the refrigeration device. Thus, the freezing air duct will occupy the entire back space of the freezing compartment, and the return air duct of the refrigerating compartment extends in the entire height space of the refrigeration device. The entire length of the return air duct is relatively long, and the volume of the compartment will inevitably be restricted.

[0003] In view of this, it is necessary to improve the existing refrigeration device to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a refrigeration device that can increase the volume of the storage compartment and reduce the cost of the air duct.

[0005] To achieve the above-mentioned invention purpose, the present invention provides a refrigeration device, which includes a box body formed with a storage compartment, an evaporator arranged in the box body. The box body forms a refrigerating chamber at the rear side of the storage compartment. The evaporator is arranged in the refrigerating chamber. The storage compartment has a first storage area and a second storage area that are vertically communicated. The refrigerating chamber is located at the rear side of the first storage area and is spaced from the bottom wall of the storage compartment through the second storage area. The depth of the second storage area extending backward is deeper than the depth of the first storage area.

[0006] As a further improvement of the present invention, the box body also has an air duct, a partition air duct and an air duct cover plate of the storage compartment arranged between the storage compartment and the refrigerating chamber. The top of the air duct is communicated with the refrigerating chamber, and a plurality of air outlets communicated with the storage compartment are opened on the air duct cover plate.

[0007] As a further improvement of the present invention, the air duct cover plate is located in front of the rear wall of the second storage area, and the air outlets are located above the second storage area.

[0008] As a further improvement of the present invention, the air duct cover plate has a front cover plate and a rear cover plate that cooperate with the front cover plate. A plurality of the air outlets for sending air to the storage compartment are arranged on the front cover plate. The rear cover plate and the box body define a first return air outlet located at the bottom end of the rear cover plate. The first return air outlet is arranged behind the second storage area.

[0009] As a further improvement of the present invention, the rear cover plate has a substrate portion and a front protrusion protruding forward from the substrate portion. The front protrusion is located below the air outlet and protrudes forward to cover the gap between the second storage area and the rear cover plate on the upper side.

[0010] As a further improvement of the present invention, the distance h1 between the first storage area and the bottom wall of the storage compartment is not less than the distance h2 between the first storage area and the second storage area, and the relationship between the distance h1 between the first storage area and the bottom wall of the storage compartment and the distance h2 between the first storage area and the second storage area is h1≥h2 + 4mm.

[0011] As a further improvement of the present invention, the distance h3 in the vertical direction between the upper end edge of the front protrusion and the rear wall of the second storage area is 8mm≥h3≥5mm.

[0012] As a further improvement of the present invention, the substrate portion has a first substrate segment on the upper side, a second substrate segment on the lower side, and an inclined segment connecting the first substrate segment and the second substrate segment. The front protrusion is formed by protruding forward from the connection of the inclined segment and the second substrate segment, and the distance d between the second substrate segment and the rear end edge of the second storage area is 8mm≥d≥5mm.

[0013] As a further improvement of the present invention, a third storage area is further provided in the storage compartment above the second storage area. At least part of the evaporator is located at the rear of the third storage area, and the front protrusion is located below the third storage area.

[0014] As a further improvement of the present invention, the first and second storage areas are storage drawers, and air-permeable holes are provided on their left and right side walls to penetrate them for cold air circulation.

[0015] Advantages of the present invention: By arranging the refrigeration chamber where the evaporator is placed at the rear of the first storage area, and separating the refrigeration chamber from the bottom wall of the storage compartment by the second storage area, and the depth of the second storage area extending backward is deeper than the depth of the first storage area, the present invention's refrigeration device shortens the lengths of the refrigerated return air duct and the freezing air duct, increases the volume of the storage compartment, and reduces the air duct cost.

[0027] The present invention will be described in detail below in conjunction with the embodiments shown in the drawings. However, this embodiment does not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on this embodiment is included within the protection scope of the present invention.

[0028] Spatial relative position terms such as "upper", "lower", "left", "right", "front", "rear", etc. used herein are for the purpose of facilitating description of the relationship between one feature and another as shown in the drawings. It can be understood that depending on the placement position of the product, the spatial relative position terms may be intended to include different orientations other than those shown in the figures, and should not be construed as a limitation on the claims. In addition, the descriptive term "horizontal" used herein is not exactly equivalent to being perpendicular to the direction of gravity and allows for a certain degree of inclination.

[0029] Please refer to Figures 1 to 11The figure shows a schematic diagram of the refrigeration device of the present invention. The refrigeration device includes a box body 1 formed with a storage compartment 100, and an evaporator 2 disposed inside the box body 1. The box body 1 forms a refrigeration chamber 101 at the rear side of the storage compartment 100, and the evaporator 2 is disposed inside the refrigeration chamber 101. For the convenience of description, hereinafter, the side of the box body 1 close to the user is regarded as the front side, and the opposite side is regarded as the rear side. At the same time, one direction perpendicular to the front-rear direction is regarded as the left-right direction (also called the lateral direction), and the other direction perpendicular to the front-rear direction is regarded as the up-down direction (also called the height direction).

[0030] The storage compartment 100 has a first storage area 31 and a second storage area 32 that are vertically connected. The refrigeration chamber 101 is located at the rear side of the first storage area 31 and is separated from the bottom wall 102 of the storage compartment 100 through the second storage area 32. The depth of the second storage area 32 extending backward is deeper than the depth of the first storage area 31.

[0031] Specifically, the second storage area 32 has a deepening portion 321 formed by protruding backward. The deepening portion 321 is located below the evaporator 2. Since the evaporator 2 is disposed higher up, space occupancy is saved. Therefore, a deeper storage area can be formed behind the second storage area 32, that is, the deepening portion 321 is formed, thereby increasing the storage space of the refrigeration device.

[0032] The box body 1 further has an air duct disposed between the storage compartment 100 and the refrigeration chamber 101, a partition air duct, and an air duct cover plate 4 of the storage compartment 100. The top of the air duct is connected to the refrigeration chamber 101, and a plurality of air outlets 412 communicating with the storage compartment 100 are opened on the air duct cover plate 4. In this embodiment, the storage compartment 100 is a freezer compartment, and the air outlets 412 are first air outlets for blowing air toward the freezer compartment. The air duct between the storage compartment 100 and the refrigeration chamber 101 is a freezer air duct.

[0033] The air duct cover plate 4 is located on the front side of the rear wall of the second storage area 32, and the air outlets 412 are located on the upper side of the second storage area 32.

[0034] In the present invention, a third storage area 33 is further provided in the storage compartment 100 above the second storage area 32, that is, the first storage area 31, the second storage area 32, and the third storage area 33 are arranged in sequence from bottom to top. At least a part of the evaporator 2 is located above the second storage area 32 and at least partially located at the rear of the third storage area 33, so as to increase the storage space of the storage compartment 100 below the evaporator 2. Specifically, in this embodiment, the evaporator 2 is placed in a standing posture in the refrigerating chamber 101, and the first, second, and third storage areas 31, 32, and 33 are all storage drawers.

[0035] The distance h1 between the first storage area 31 and the bottom wall 102 of the storage compartment 100 is not less than the distance h2 between the first storage area 31 and the second storage area 32, so that air can pass through the gap between the first storage area 31 and the bottom wall 102 of the box body 1, thereby ensuring the temperature requirement of the first storage area 31.

[0036] Further, the relationship between the distance h1 between the first storage area 31 and the bottom wall 102 of the storage compartment 100 and the distance h2 between the first storage area 31 and the second storage area 32 is h1 ≥ h2 + 4 mm; in this way, by making the distance h2 between the first storage area 31 and the second storage area 32 small enough, it is more conducive to air flowing through the gap between the first storage area 31 and the bottom wall 102, so as to ensure that even after the compressor and the blower stop, the cold air sinking naturally can still ensure that the temperature of the first storage area 31 is lower than -18°C.

[0037] Preferably, in this embodiment, the distance h1 between the first storage area 31 and the bottom wall 102 is 14 mm; the distance h2 between the first storage area 31 and the second storage area 32 is 10 mm.

[0038] The air duct cover plate 4 has a front cover plate 41 and a rear cover plate 42 that cooperates with the front cover plate 41. A plurality of air outlets 412 for sending air to the storage compartment 100 are provided on the front cover plate 41. The rear cover plate 42 and the box body 1 define a first air return opening 401 at the bottom end of the rear cover plate 42, and the first air return opening 401 is provided behind the second storage area 32.

[0039] The first air return opening 401 is located above the deepening portion 321 and directly above the deepening portion 321. Further, the first air return opening 401 is located below the upper end edge of the rear wall of the second storage area 32, so as to make the air return channel longer while controlling the cost of the air return channel.

[0040] Such as Figure 5 、Figure 6 and Figure 11 As shown in Figure 11 , the rear cover plate 42 has a substrate portion 421 and a front protruding portion 423 protruding forward from the substrate portion 421. The front protruding portion 423 is located below the air outlet 412 and protrudes forward to block the gap between the second storage area 32 and the rear cover plate 42 on the upper side, so as to prevent the cold air from flowing back prematurely from the rear back of the second storage area 32. Preferably, the front protruding portion 423 protrudes forward and covers the rear wall of the second storage area 32. The distance between the upper end edge of the front protruding portion 423 and the rear wall of the second storage area 32 in the vertical direction is h3, and 8mm ≥ h3 ≥ 5mm.

[0041] The substrate portion 421 has a first substrate segment 4211 located on the upper side, a second substrate segment 4213 located on the lower side, and an inclined segment 4212 connecting the first substrate segment 4211 and the second substrate segment 4213. The inclined segment 4212 extends forward and downward from the first substrate segment 4211. The front protruding portion 423 is formed by protruding forward from the connection of the inclined segment 4212 and the second substrate segment 4213, and the front protruding portion 423 is located below the third storage area 33.

[0042] And, as Figure 11 shown, the distance between the second substrate segment 4213 and the rear end edge of the second storage area 32 is d, and 8mm ≥ d ≥ 5mm, so as to ensure the normal return air of the refrigeration air duct. In particular, it can ensure that there is enough cold air passing through the first storage area 31 at the bottom layer and reduce the air volume passing through the gap between the second substrate segment 4213 and the rear end edge of the second storage area 32.

[0043] The air duct cover plate further includes an air duct structural member provided at the rear side of the refrigeration chamber 101. The air duct structural member is formed with a supply air channel and a return air channel connecting the refrigerating chamber and the refrigeration chamber 101. The refrigeration device further includes a fan 5 provided in the channel. The rear cover plate 42 and the box body 1 define the refrigeration chamber 101. The fan 5 is fixed on the front cover plate 41, and the refrigeration chamber 101 is connected to the compressor chamber through a pipeline 6.

[0044] The air duct structural member includes a return air structural member and a supply air structural member. The supply air structural member includes a first supply air structural member 431 and a second supply air structural member 432. The return air structural member includes a first return air structural member 441 and a second return air structural member 442. The first supply air structural member 431 and the first return air structural member 441 are integrally connected in the transverse direction. The first and second supply air members 431, 432 are combined to form a supply air outlet 434 for delivering cold air to the refrigerating chamber. The second supply air structural member 432 and the second return air structural member 442 are integrally connected in the transverse direction. The first and second return air structural members 441, 442 are combined to form a second return air outlet 443 for the gas in the refrigerating chamber to flow into the refrigerating return air duct. The second return air structural member 442 is provided with a third return air outlet 445 communicating with the refrigerating chamber 101 for the gas flowing back into the refrigerating return air duct to flow into the refrigerating chamber 101. Since the evaporator 2 is set at a relatively high position at the back of the storage room, the refrigerating return air duct formed by the buckling of the first and second return air structural members 441, 442 is relatively short, thereby reducing the cost of the air duct.

[0045] The bottom end of the front cover plate 41 is located directly behind the third storage area 33. The rear cover plate 42 and the front cover plate 41 are spaced apart to form a second air outlet 413 at the bottom end of the front cover plate 41. The second air outlet 413 is open downward to deliver cold air downward to the third storage area 33 and the second and first storage areas 32, 31 below it.

[0046] In addition, the rear cover plate 42 further has a retaining edge 424 formed by protruding forward from the first substrate section 4211. The retaining edge 424 is integrally arc-shaped and is located above the protruding portion 423 to initially block and adjust the direction of the cold air sent downward from the second air outlet 413 to prevent too much air volume from flowing directly downward. In this embodiment, the length of the retaining edge 424 protruding forward is less than the length of the inclined section 4212 protruding forward. The inclined section 4212 and the protruding portion 423 are below the retaining edge 424 to block and adjust the direction of the cold air again.

[0047] In this embodiment, the first and second storage areas 31, 32 are storage drawers, and air-permeable holes 301 are provided on the left and right side walls of the first and second storage areas 31, 32 to penetrate them for cold air circulation. Specifically, the air-permeable holes 301 are provided in the lower half of the first and second storage areas 31, 32, that is, the air-permeable holes 301 on both sides of the first storage area 31 are close to the bottom wall of the first storage area 31, and the air-permeable holes 301 on both sides of the second storage area 32 are close to the bottom wall of the second storage area 32, so as to be more conducive to the circulation of cold air that naturally sinks.

[0048] In the present invention, the refrigeration device shortens the lengths of the refrigerated return air duct and the freezing air duct, increases the volume of the storage room, and reduces the air duct cost by arranging the refrigeration chamber 101 where the evaporator 2 is placed at the rear side of the first storage area 31, and separating the refrigeration chamber 101 from the bottom wall 102 of the storage room 100 by the second storage area 32, and the depth of the second storage area 32 extending backward is deeper than the depth of the first storage area 31.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
