Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a horizontal freezer. Background Technology

[0002] Existing air-cooled horizontal freezers place the evaporator above the step, resulting in a small space above the step, limiting the number of items that can be placed there. After a few uses, the step surface will be exposed. In addition, the bottom space next to the step is quite deep, requiring users to bend over significantly when reaching for items at the bottom. Summary of the Invention

[0003] The purpose of this application is to provide a horizontal freezer in which the evaporator compartment is arranged horizontally alongside the step, thereby reducing the probability of users having to bend over significantly to retrieve items in the prior art.

[0004] To achieve one of the above-mentioned objectives, one embodiment of this application provides a horizontal freezer, comprising:

[0005] The housing includes an inner liner forming a refrigeration chamber and an outer shell fitted over the inner liner. A compressor compartment is formed at the bottom of the housing. The inner liner has a stepped portion located at the bottom of one end of the refrigeration chamber. The stepped portion includes a stepped top plate located above the compressor compartment.

[0006] An evaporator compartment is formed in the refrigeration compartment, the evaporator compartment and the stepped portion are parallel in a first direction, and the top of the middle part of the evaporator compartment is lower than the top plate of the stepped portion.

[0007] In one embodiment of this application, the inner liner further includes a bottom plate. In a first direction, the bottom plate is located on the side of the evaporator compartment away from the step. In the vertical direction, the height difference between the top plate of the step and the top of the middle position of the evaporator compartment is not greater than 1 / 2 of the height difference between the top plate of the step and the bottom plate.

[0008] In one embodiment of this application, the inner liner further includes two first sidewalls, which are parallel to a first direction; the horizontal freezer further includes an evaporator compartment cover plate fixed to the inner liner, which, together with the two first sidewalls and the step portion, encloses the evaporator compartment.

[0009] In one embodiment of this application, the evaporator compartment cover plate includes a first compartment cover plate, a second compartment cover plate, and a return air cover plate. The first compartment cover plate and the second compartment cover plate are spaced apart along a second direction and are both L-shaped. The return air cover plate connects the first compartment cover plate and the second compartment cover plate, wherein the second direction is horizontal and perpendicular to the first direction.

[0010] In one embodiment of this application, a heat insulation plate is provided on the inner side of the evaporator compartment cover plate. The heat insulation plate includes a first heat insulation plate and a second heat insulation plate spaced apart along a second direction. The distance between the first heat insulation plate and the second heat insulation plate is less than the distance between the first compartment cover plate and the second compartment cover plate. Furthermore, a return air vent is defined between the first heat insulation plate and the second heat insulation plate.

[0011] In one embodiment of this application, the first heat insulation plate and / or the second heat insulation plate are provided with air guide grooves, which extend toward the return air inlet.

[0012] In one embodiment of this application, an air duct is further included. The air duct is fixed to the first sidewall and communicates with the evaporator compartment. The air duct includes an upper air duct, a lower air duct, and a vertical air duct. The upper air duct and the lower air duct are spaced apart in the vertical direction. The vertical air duct connects the upper air duct and the evaporator compartment. Both the upper air duct and the lower air duct are provided with multiple air outlets at intervals.

[0013] In one embodiment of this application, the air duct is configured as an air outlet duct, and the vertical air duct is provided with a side air outlet. In a first direction, the air outlet of the side air outlet is directed toward the side of the stepped portion.

[0014] In one embodiment of this application, an evaporator and a fan assembly are further disposed in the evaporator chamber. The evaporator and the fan assembly are arranged side by side in a second direction, and the air duct is connected to the fan assembly. The second direction is horizontal and perpendicular to the first direction.

[0015] In one embodiment of this application, the fan assembly is provided in two sets, and the two sets of fan assemblies are arranged at both ends of the evaporator compartment along a second direction.

[0016] In one embodiment of this application, the fan assembly includes a volute and an evaporator fan disposed within the volute. The height of the volute is not lower than the height of the step portion, such that both ends of the evaporator chamber are not lower than the height of the step portion and extend inclined towards the center.

[0017] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0018] In the horizontal freezer provided in this application, the evaporator compartment is arranged side by side with the step in the horizontal direction, so that the evaporator compartment occupies part of the bottom space and gives up the upper space of the step, making the deeper space in the horizontal freezer smaller; and the height of the evaporator compartment is lower than the height of the step. In order to ensure that the evaporator produces sufficient cooling capacity, the evaporator needs to be made larger and thinner, so that the evaporator compartment occupies a larger bottom area, further reducing the deep space.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] The terms used in this document, such as “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicating spatial relative positions, are used for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative positions” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0040] For example, if the device in the figure is flipped, a unit described as being "below" or "under" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise) and the spatially related descriptive terms used herein will be interpreted accordingly.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first sidewall may be referred to as a second sidewall, and similarly, a second sidewall may be referred to as a first sidewall, without departing from the scope of protection of this application.

[0043] This application provides a horizontal freezer, such as... Figures 1-3 As shown, the device includes a housing and an evaporator compartment 30. The housing includes an inner liner 1 and an outer shell 2. The inner liner 1 forms a refrigeration chamber 11. The outer shell 2 is fitted over the inner liner 1. A compressor compartment is formed at the bottom of the housing. The inner liner 1 has a step portion 12 located at the bottom of one end of the refrigeration chamber 11. The step portion 12 includes a step top plate 121 located above the compressor compartment.

[0044] Evaporator compartment 30 is formed in refrigeration compartment 11. Evaporator compartment 30 and step portion 12 are parallel in the first direction. The top of the middle part of evaporator compartment 30 is lower than the top plate 121 of step.

[0045] The step section 12 inside the refrigeration compartment 11 of the horizontal freezer is reserved for the space to place the compressor, that is, the compressor compartment is set below the step section 12.

[0046] In this application, the evaporator compartment 30 is placed side by side with the step portion 12 in the horizontal direction, freeing up the space above the step portion 12, thereby increasing the storage space above the step portion 12 and enabling the storage of more items.

[0047] In addition, since the evaporator compartment 30 has a certain height, the bottom of the refrigeration compartment 11 next to the step 12 is raised, reducing the probability that users have to bend over a lot to pick up items at the bottom.

[0048] Furthermore, as the height of the evaporator compartment 30 decreases, its width, or the area it occupies in the horizontal direction, will increase, which can further reduce the probability of users bending over significantly.

[0049] In some embodiments of this application, the inner liner 1 further includes a bottom plate 13. In a first direction, the bottom plate 13 is located on the side of the evaporator compartment 30 away from the step portion 12. In the vertical direction, the portion of the step portion 12 that is higher than the top of the middle position of the evaporator compartment 30 is not greater than 1 / 2 of the height difference between the top of the step portion 12 and the bottom plate 13.

[0050] The bottom plate 13 is the bottom wall of the refrigeration chamber 11 located on the side of the evaporator compartment 30 away from the step 12. The height of the evaporator compartment 30 and the height of the step 12 are both the difference in vertical distance between their tops and the bottom plate 13.

[0051] The portion of the top plate 121 above the middle position of the evaporator compartment 30 is not greater than 1 / 2 of the height difference between the top of the step portion 12 and the bottom plate 13, that is, the height of the evaporator compartment 30 is not less than 0.5 times the height of the step portion 12.

[0052] On the one hand, this is due to considerations regarding the height of the evaporator 6 installed inside the evaporator compartment 30; on the other hand, if the evaporator compartment 30 is too low, it cannot effectively raise the bottom of the refrigeration compartment 11.

[0053] In some embodiments of this application, the inner liner 1 further includes two first sidewalls 14, which are parallel to the first direction and are disposed opposite to each other.

[0054] The horizontal freezer also includes an evaporator compartment cover 3 fixed to the inner liner 1, and the evaporator compartment cover 3, together with the two first side walls 14 and the step portion 12, forms an evaporator compartment 30.

[0055] like Figure 3 In the middle, the first side wall 14 are the two longer side walls of the horizontal freezer. When the freezer is used in the bedroom, these two first side walls 14 are the front wall and the back wall.

[0056] In addition to the first sidewall 14, the inner liner 1 also includes two second sidewalls 15. The two second sidewalls 15 are connected to the two first sidewalls 14, and the two second sidewalls 15 are also arranged opposite to each other. The step portion 12 is arranged against one of the second sidewalls 15. The two second sidewalls 15 are the left wall and the right arm.

[0057] That is, the first direction is the left and right direction.

[0058] The inner liner 1 also includes a support member 4, which includes a side part 41 and a bottom part 42.

[0059] The side portion 41 is formed as a side wall of the evaporator compartment 30 near the step portion 12, and is also a part of the side wall of the step portion 12 near the evaporator compartment 30. The bottom portion 42 is disposed at the bottom of the evaporator compartment 30 and formed on its bottom wall.

[0060] This allows the evaporator compartment cover 3, the two first side walls 14, and the support member 4 to enclose and form the evaporator compartment 30, with the side walls of the evaporator compartment 30 and the side walls of the step portion 12 being coplanar.

[0061] Of course, the evaporator compartment 30 can also be located in the middle of the refrigeration compartment 11. In this case, the evaporator compartment cover 3 and the two first side walls 14 together form the evaporator compartment 30.

[0062] Alternatively, it can be located at the end opposite to the step portion 12, in which case the evaporator compartment cover 3, together with the two first side walls 14 and the second side wall 15, forms the evaporator compartment 30.

[0063] In some embodiments of this application, the evaporator compartment cover 3 includes a first compartment cover 31, a second compartment cover, and a return air cover 32.

[0064] like Figure 2 , 3 Among them Figure 2 , 3 The return air cover 32 is hidden inside, and Figure 3 This is a sectional view, showing only the first compartment cover 31 located at the front. The first compartment cover 31 and the second compartment cover are spaced apart along the second direction and are both L-shaped. The return air cover 32 connects the first compartment cover 31 and the second compartment cover.

[0065] The second direction is horizontal and perpendicular to the first direction, that is, the second direction is the left and right direction.

[0066] Since the evaporator compartment 30 is adjacent to the step portion 12, the two first side walls 14 are formed as the front and rear walls of the evaporator compartment 30, and the side wall of the step portion 12 near the evaporator compartment 30 is formed as one of the side walls of the evaporator compartment 30. Then the evaporator compartment cover plate 3 is L-shaped and is formed as the other side wall and the top wall of the evaporator compartment 30 respectively.

[0067] The evaporator compartment cover 3 includes an L-shaped first compartment cover 31 and a second compartment cover that are spaced apart, so that an L-shaped opening is formed in the side wall and top wall of the evaporator compartment 30.

[0068] The L-shaped opening can be used for return air, and the opening is covered by the return air cover 32 to prevent items from falling into the evaporator compartment 30. Of course, the return air cover 32 has through holes for airflow to pass through.

[0069] The return air cover 32 is also L-shaped. The return air cover 32 includes several L-shaped narrow plates 321 arranged sequentially along the second direction. Among two adjacent L-shaped narrow plates 321, one is closer to the evaporator compartment 30, while the other is closer to the refrigeration compartment 11, so that the return air cover 32 forms an upper structure.

[0070] Among them, the narrow plate 321 on the side closer to the evaporator compartment 30 is the inner narrow plate 3212, and the narrow plate 321 on the side away from the evaporator compartment 30 is the outer narrow plate 3211. The inner narrow plate 3212 and the outer narrow plate 3211 are arranged sequentially along the second direction.

[0071] In any direction perpendicular to the L-shaped narrow plate 321, the inner narrow plate 3212 and the outer narrow plate 3211 do not overlap.

[0072] An opening for air circulation is formed between two adjacent outer narrow plates 3211, and an inner narrow plate 3212 is provided inside it; similarly, an opening for air circulation is also formed between two adjacent inner narrow plates 3212, and an outer narrow plate 3211 is provided outside it.

[0073] Air in the refrigeration chamber 11 flows from the opening between the two outer narrow plates 3211 toward the evaporator chamber 30. When it encounters the inner narrow plate 3212 between the two outer narrow plates 3211, it can no longer flow toward the evaporator chamber 30, but can only flow to both sides and enter the evaporator chamber 30 between the two narrow plates 321.

[0074] Therefore, when an item is placed on the outside of the return air cover 32 (on the side closer to the refrigeration compartment 11), the air around the item can enter the evaporator compartment 30 between the two adjacent outer narrow plates 3211.

[0075] Since the evaporator compartment 30 and the step portion 12 are arranged adjacent to each other, and the step portion 12 is located at one end of the housing, most of the space of the refrigeration compartment 11 is located on the side of the evaporator compartment 30 away from the step portion 12.

[0076] Several air guide vanes 322 are connected between two adjacent L-shaped narrow plates 321. The air guide vanes 322 extend obliquely from top to bottom toward the side where the step portion 12 is provided, which is conducive to the air on the opposite side of the step portion 12 entering the evaporator chamber 30.

[0077] In some embodiments of this application, an insulation plate is provided on the inner side of the evaporator compartment cover plate 3, and the insulation plate includes a first insulation plate 33 and a second insulation plate spaced apart along a second direction.

[0078] The distance between the first heat insulation plate 33 and the second heat insulation plate is less than the distance between the first compartment cover plate 31 and the second compartment cover plate, and a return air vent 34 is defined between the first heat insulation plate 33 and the second heat insulation plate.

[0079] Installing a heat insulation plate on the inside of the evaporator cover plate 3 can prevent the cold energy generated by the evaporator from being directly transferred to the refrigeration chamber 11 through the evaporator cover plate 3, which would cause the evaporator cover plate 3 to be too cold and prone to frost formation.

[0080] The first heat insulation plate 33 and the second heat insulation plate are also L-shaped and have a large area, which can cover the first compartment cover plate 31 and the second compartment cover plate respectively and protrude, so that the return air vent 34 is defined between the first heat insulation plate 33 and the second heat insulation plate.

[0081] The air in the refrigeration compartment 11 is returned through the evaporator compartment cover 3, and the air drawn in through the return air inlet 34 directly enters the evaporator compartment 30, resulting in minimal air volume loss.

[0082] In some embodiments of this application, the first heat insulation plate 33 and / or the second heat insulation plate are provided with air guide grooves 331, which extend toward the return air vent 34.

[0083] Since the first heat insulation plate 33 and the second heat insulation plate protrude from the first compartment cover plate 31 and the second compartment cover plate respectively, air guide grooves 331 are provided on the parts of the first heat insulation plate 33 and / or the second heat insulation plate that protrude from the first compartment cover plate 31 and the second compartment cover plate to guide the air passing through the return air cover plate 32 to the return air inlet 34.

[0084] The air guide duct 331 can be set on the top and / or side of the first heat insulation plate 33 and / or the second heat insulation plate.

[0085] In some embodiments of this application, the horizontal freezer also includes an air duct, which is fixed to the first side wall 14 and communicates with the evaporator compartment 30.

[0086] like Figure 3 In the middle, the air duct includes an upper air duct 51, a lower air duct 52 and a vertical air duct 53. The upper air duct 51 and the lower air duct 52 are arranged at intervals in the vertical direction. The vertical air duct 53 connects the upper air duct 51 and the evaporator compartment 30. Both the upper air duct 51 and the lower air duct 52 are provided with multiple air outlets at intervals.

[0087] The upper air duct 51 and the lower air duct 52 extend along the first direction, and both ends of the upper air duct 51 and the lower air duct 52 are close to the second side wall 15. In other words, the upper air duct 51 and the lower air duct 52 extend from one end of the refrigeration room 11 to the other end.

[0088] The air duct can be either an exhaust air duct or a return air duct. Since the return air is located on the evaporator compartment cover plate 3 in this application, the air duct fixed to the first side wall 14 is more suitable for exhaust air.

[0089] Two horizontal air ducts, one high and one low, are provided on the first side wall 14 to ensure the uniformity of airflow in the cooling room 11 in both the length and height directions.

[0090] Of course, the air duct can also be provided with only one upper air duct 51 and connected to the evaporator compartment 30 through the vertical air duct 53, or only one lower air duct 52 connected to the evaporator compartment 30.

[0091] You can also set only one located in, such as Figure 3 The horizontal air duct between the upper-middle air duct 51 and the lower-middle air duct 52, or in Figure 3 A horizontal air duct is added between the upper-middle air duct 51 and the lower-middle air duct 52.

[0092] In some embodiments of this application, the upper air duct 51 and the vertical air duct 53 are formed protruding from the inner liner 1 toward the outer shell 2, and the lower air duct 52 is formed protruding from the inner liner 1 toward the interior of the refrigeration compartment 11.

[0093] In horizontal freezers, food baskets are usually hung above the refrigeration compartment 11 to increase partitioning. The upper air duct 51 and the vertical air duct 53 are hidden between the inner liner 1 and the outer shell 2, so they will not interfere with the installation of the food baskets, nor will the protruding air ducts at the top reduce the distance between the front and back of the food baskets.

[0094] The downdraft duct 52 protrudes from the refrigeration chamber 11 and can serve as a mounting bracket for the food basket, thus sharing some of the load on the food basket.

[0095] Regarding the installation of the upwind duct 51 and the downwind duct 52, the specifics are as follows: Figure 6 middle.

[0096] The upper air duct 51 includes an upper air duct shell 511 and an upper air duct cover 512. The upper air duct shell 511 forms an upper air duct cavity with an opening facing the refrigeration chamber 11, and the upper air duct cover 512 covers the opening of the upper air duct cavity.

[0097] The upper air duct shell 511 is provided with a first upper slot 5111 and a first lower slot 5112. The first upper slot 5111 and the first lower slot 5112 are located at the top and bottom of the upper air duct shell 511, and the openings of the first upper slot 5111 and the first lower slot 5112 face the refrigeration chamber 11.

[0098] The upper air duct cover 512 is provided with an upper flange 5121 and a lower flange 5122. The upper flange 5121 and the lower flange 5122 are provided at the top and bottom of the upper air duct cover 512, respectively, and are provided in the first upper slot 5111 and the first lower slot 5112, so that the upper air duct cover 512 is fixed to the upper air duct shell 511.

[0099] The bottom of the upper air duct housing 511 extends downward near the opening of the upper air duct cavity and is provided with a fixing slot 5113. The top of the first side wall 14 is disposed in the fixing slot 5113, so that the upper air duct 51 is fixed to the first side wall 14. Furthermore, the upper air duct cover plate 512 is flush with the first side wall 14.

[0100] The downdraft duct 52 includes a downdraft duct cover 521, an upper reinforcing strip 522, and a lower reinforcing strip 523.

[0101] The cross-section of the downdraft cover 521 is C-shaped, and both the upper reinforcing strip 522 and the lower reinforcing strip 523 are L-shaped.

[0102] One end of the L-shaped upper reinforcing strip 522 is fixed to the first side wall 14, and the other end has a second upper slot 5221 with an opening facing the refrigeration chamber 11.

[0103] One end of the L-shaped lower reinforcing strip 523 is fixed to the first side wall 14, and the other end has a second lower slot 5231 with an opening facing the refrigeration chamber 11.

[0104] The upper and lower ends of the downdraft cover 521 are respectively inserted into the second upper slot 5221 and the second lower slot 5231, so that the downdraft cover 521 is fixed to the first side wall 14 and together with the first side wall 14 to form a downdraft cavity.

[0105] like Figure 7 In the middle, the vertical air duct 53 includes a vertical air duct shell 531 and a vertical air duct cover 532. The vertical air duct shell 531 forms a vertical air duct cavity with an opening facing the refrigeration chamber 11, and the vertical air duct cover 532 covers the opening of the vertical air duct cavity.

[0106] Similar to the upper air duct 51, the vertical air duct cover 532 is provided with a left flange and a right flange. The left flange and the right flange are provided on the left and right sides of the vertical air duct cover 532, respectively, and are positioned inside the vertical air duct cavity for positioning the vertical air duct cover 532.

[0107] like Figure 7 In the middle, the upper air duct shell 511, the vertical air duct shell 531 and the support member 4 are integrated into one piece, which is a plastic part and serves as part of the inner liner 1.

[0108] The upper air duct cover plate 512 and the vertical air duct cover plate 532 are integrated and are installed together on the upper air duct cavity and the vertical air duct cavity.

[0109] The inner liner 1 also includes a U-shaped large enclosure 16, a U-shaped small enclosure 18, and a small bottom plate 19. The large enclosure 16, the bottom plate 13, the small enclosure 18, and the small bottom plate 19 are all sheet metal parts.

[0110] The inner liner 1 is composed of the large enclosure panel 16, the bottom plate 13, the small enclosure panel 18, the small bottom plate 19, the upper air duct shell 511, the vertical air duct shell 531, and the support member 4.

[0111] The evaporator compartment 30 is located on the side away from the step portion 12 in the refrigeration chamber 11 formed by the large enclosure panel 16 and the large bottom plate 17; the portion above the step portion 12 in the refrigeration chamber 11 is formed by the small enclosure panel 18 and the small bottom plate 19.

[0112] In some embodiments of this application, the horizontal freezer provided in this application further includes an evaporator 6 and a fan assembly 7. The evaporator 6 and the fan assembly 7 are disposed in the evaporator compartment 30. In the second direction, the evaporator 6 and the fan assembly 7 are arranged side by side, and the air duct is connected to the fan assembly 7.

[0113] Evaporator 6 is located in evaporator compartment 30 to provide cooling capacity to cooling room 11, and fan assembly 7 is used to blow the cooling capacity generated by evaporator 6 to cooling room 11.

[0114] The fan assembly 7 is arranged side by side with the evaporator 6 in the second direction, which can reduce the space of the evaporator compartment 30.

[0115] In some embodiments of this application, two sets of fan assemblies 7 are provided, and the two sets of fan assemblies 7 are arranged at both ends of the evaporator compartment 30 along the second direction.

[0116] If two sets of fan components 7 are provided, then two air ducts are also provided, and the two air ducts are fixed to two oppositely arranged first side walls 14 respectively.

[0117] Both air ducts can be either supply air ducts or return air ducts, or one can be a supply air duct and the other a return air duct.

[0118] In some embodiments of this application, the fan assembly 7 includes a volute 71 and an evaporator fan 72 disposed within the volute 71. The height of the volute 71 is not lower than the height of the step portion 12, such that both ends of the evaporator chamber 30 are not lower than the height of the step portion 12 and extend inclined towards the center.

[0119] The volute 71 is relatively tall, and the matching evaporator fan 72 is also relatively tall, which can reduce the air delivery distance and increase the air delivery speed. In addition, the larger evaporator fan 72 generates a larger air volume.

[0120] In some embodiments of this application, such as Figure 10 , 11 In the volute 71, there are a first air vent 713, a second air vent 714 and a third air vent 715. The first air vent 713 faces the evaporator 6, the second air vent 714 opens upward, and the third air vent 715 opens horizontally.

[0121] The first air vent 713 faces the evaporator 6 and is used to draw the cold energy of the evaporator 6 into the volute 71 and then discharge it through the second air vent 714 and the third air vent 715.

[0122] Alternatively, the air in the cooling chamber 11 can be blown to the evaporator 6 through the first air vent 713 for heat exchange. The second air vent 714 and the third air vent 715 are connected to the vertical air duct 53 and the downdraft air duct 52, respectively.

[0123] In some embodiments of this application, the volute 71 is at least partially disposed between the inner liner 1 and the outer liner 2. The volute 71 includes a front cover 711 and a rear cover 712. The front cover 711 has a first air vent 713, and the rear cover 712 is disposed opposite to the front cover 711.

[0124] It should be noted that the "front" and "rear" in the front cover 711 and rear cover 712 here are not directional. The front cover 711 refers only to the cover on the side closer to the evaporator 6, and the rear cover 712 refers only to the cover on the side away from the evaporator 6. This is different from the directional indication of the front and rear in the front and rear walls of the aforementioned refrigeration chamber 11.

[0125] The front cover 711 extends towards the outer shell 2 from the end near the second air vent 714 to join the first side wall 14 of the inner liner 1, and the rear cover 712 extends towards the interior of the refrigeration compartment 11 from the end near the third air vent 715 to join the first side wall 14 of the inner liner 1.

[0126] Since the vertical air duct 53 extends from the inner liner 1 to the outer shell 2 and is located between the inner liner 1 and the outer shell 2, the wall of the vertical air duct 53 on the side near the refrigeration chamber 11 is flush with the inner liner 1.

[0127] The lower air duct 52 extends from the inner liner 1 into the refrigeration compartment 11, and the wall of the lower air duct 52 near the outer shell 2 is flush with the inner liner 1.

[0128] The vertical air duct 53 and the downwind duct 52 are not coplanar, which also means that the second air outlet 714 and the third air outlet 715, which are connected to the vertical air duct 53 and the downwind duct 52 respectively, are also not coplanar.

[0129] The volute 71 is at least partially disposed between the inner liner 1 and the outer liner 2. The front cover 711 of the volute 71 is disposed on the side of the inner liner 1 near the refrigeration chamber 11, and the rear cover 712 of the volute 71 is disposed on the side of the inner liner 1 near the outer liner 2.

[0130] Extend the end of the front cover 711 near the second air vent 714 toward the outer shell 2 until it joins with the first side wall 14, so that the second air vent 714, like the vertical air duct 53, is located between the inner liner 1 and the outer shell 2.

[0131] Extend the end of the back cover 712 near the third air vent 715 toward the side of the refrigeration chamber 11 to join with the first side wall 14, so that the third air vent 715, like the downdraft duct 52, is located on the side of the inner liner 1 near the refrigeration chamber 11.

[0132] In some embodiments of this application, a drainage hole 716 is provided at the bottom of the volute 71.

[0133] The evaporator fan 72 may frost during the evaporator 6 cooling process, and defrosting is required by the heating wire.

[0134] To prevent defrost water from being unable to drain and causing secondary icing during the subsequent evaporator 6 cooling process, which could affect the operation of the evaporator fan 72, a drain hole 716 is added to the bottom of the volute 71 to drain the defrost water.

[0135] In some embodiments of this application, the rear cover 712 of the volute 71 is provided with a wire outlet 717 for the outlet of the evaporator fan 72.

[0136] In some embodiments of this application, the air duct is configured as an air outlet duct, and the vertical air duct 53 is provided with a side air outlet 533. In the first direction, the air outlet 533 is directed toward the side of the step portion 12.

[0137] When the air duct is set as an outlet air duct, the vertical air duct 53 not only connects to the evaporator compartment 30, but also has a side air outlet 533. The air outlet 533 is directed from the vertical air duct 53 to the stepped part 12 and is blown out at an angle.

[0138] This allows the cold air generated by the evaporator 6 to be blown into the space above the step 12, avoiding the risk of insufficient cold air in the space above the step causing the product to melt.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. 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.
