Description

Liner for refrigeration equipment, box for refrigeration equipment and refrigeration equipment

Technical Field

The utility model belongs to the technical field of refrigeration equipment, and particularly provides an inner container for refrigeration equipment, a box body for refrigeration equipment and refrigeration equipment.

Background

Existing refrigeration equipment generally includes refrigerators, freezers and freezers. Existing refrigeration equipment typically provides a compressor compartment at the rear side of the bottom thereof to house the compressor, condenser and heat dissipation fan within the compressor compartment. The compressor is limited in height, so that the height of the compressor bin is large, and a large amount of space of a storage compartment in the refrigeration equipment is occupied. Wherein the storage compartment is formed in a liner of the refrigeration apparatus.

The refrigeration chamber is generally arranged between the liner and the compressor bin of the refrigeration equipment arranged at the bottom of the existing evaporator. In order to prevent the cooling leakage of the refrigerating compartment, heat insulation layers are generally arranged on the upper side and the lower side of the refrigerating compartment, so that the height of the liner is higher, and the volume utilization rate of the refrigerating equipment is lower. Meanwhile, the rear side of the bottom of the liner is required to avoid an air supply duct of the press bin and the refrigerating compartment, so that the depth of the bottom of the storage compartment in the front-rear direction is small, and the volume utilization rate of the refrigerating equipment is further reduced.

Disclosure of Invention

The utility model aims to solve the problem that the volume rate of the refrigeration equipment is low due to the fact that the bottom wall of the liner of the existing refrigeration equipment is excessively lifted.

In order to achieve the above object, in a first aspect, the present utility model provides a liner for a refrigeration apparatus, the liner including a liner body and a sink groove at a bottom of the liner body, the sink groove being located at one side of the liner body in a left-right direction, the sink groove being used for arranging an evaporator.

Optionally, the sinking groove comprises a front side part and a rear side part, wherein the bottom wall of the front side part is horizontally arranged, and the bottom wall of the rear side part is inclined upwards from front to rear; the front side is used for arranging the evaporator.

Optionally, the width of the front side is greater than half the width of the inner cavity of the liner, and the width of the rear side is less than half the width of the inner cavity of the liner.

Optionally, a drain hole is provided on the bottom wall of the front side portion.

Optionally, a middle area of the front side is used for bearing the evaporator, and the height of the middle area gradually decreases towards the direction approaching the drain hole, so that the middle area forms a funnel shape; and/or the drain hole is positioned at one side of the front side part, which is close to the container body and is not provided with the sinking groove.

Optionally, the inner bottom surface of the liner is located at the left and right sides of the front side portion, and is equal in height in the left-right direction to bear the evaporator cover plate, so that the evaporator cover plate shields the front side portion.

Optionally, the inner bottom surface of the liner is provided with cover flanges on left and right sides of the rear side portion, respectively, and the cover flanges are used for fixing the evaporator cover so that the evaporator cover covers the rear side portion.

Optionally, the liner further comprises an air duct flange arranged on the rear side wall of the liner body, and the air duct flange is used for installing an air duct cover plate, so that an air supply channel communicated with the sinking groove is defined between the air duct cover plate and the liner body.

The present utility model provides in a second aspect a cabinet for a refrigeration appliance, the cabinet comprising:

Detailed Description

It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present utility model, but not all embodiments of the present utility model, and the some embodiments are intended to explain the technical principles of the present utility model and are not intended to limit the scope of the present utility model. All other embodiments, which can be obtained by a person skilled in the art without any inventive effort, based on the embodiments provided by the present utility model, shall still fall within the scope of protection of the present utility model.

It should be noted that, in the description of the present utility model, terms such as "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate directions or positional relationships, which are based on the directions or positional relationships shown in the drawings, are merely for convenience of description, and do not indicate or imply that the apparatus or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Further, it should also be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, and can also be communicated with the inside of two elements. The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.

In addition, it should be noted that, in the description of the present utility model, the terms "cooling capacity" and "heating capacity" are two descriptions of the same physical state. That is, the higher the "cooling capacity" of a certain object (for example, evaporator, air, condenser, etc.), the lower the "heat" of the object, and the lower the "cooling capacity" of the object, the higher the "heat" of the object. Some object absorbs the cold and releases the heat, and the object releases the cold and absorbs the heat. A target maintains "cold" or "heat" to maintain the target at a current temperature. "refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, i.e., a target (e.g., an evaporator) absorbs heat while it is refrigerating.

The liner and the cabinet of the present utility model will be described in detail with reference to fig. 1 to 15 in conjunction with a refrigerating apparatus.

Wherein the refrigeration device may be a refrigerator, freezer or ice chest.

As shown in fig. 1 and 2, in some embodiments of the present utility model, a refrigeration appliance includes a cabinet 100 and a plurality of drawers 200. The plurality of drawers 200 are each mounted to the cabinet 100 in a drawer-type manner.

It should be noted that, in the present utility model, the number of drawers 200 may be any other possible number besides three as shown in fig. 1 and 2. E.g., one, two, four, etc.

Alternatively, one skilled in the art may also configure a door for the refrigerating apparatus as needed, instead of the drawer 200, and open or shield the cabinet 100 through the door.

Further, in the present utility model, the refrigeration apparatus is an air-cooled refrigeration apparatus. The drawer 200 may be a direct cooling type drawer 200 or an air cooling type drawer 200.

If the drawer 200 is a direct chill drawer 200, the drawer 200 may be provided in a completely closed form or only one opening may be provided for the drawer 200. It will be appreciated by those skilled in the art that when the drawer 200 has only one opening, no convection is formed inside the drawer 200, and thus the food material therein is cooled by direct cooling.

If the drawer 200 is an air-cooled drawer 200, openings are required to be respectively arranged at two opposite positions on the drawer 200, so that the opening at one position is used for receiving cold air, and the opening at the other position is used for guiding out air in the drawer 200, thereby enabling the cold air to flow in the drawer 200 and realizing air cooling of food materials in the drawer 200. Illustratively, an opening is provided on the rear side and the front side of the drawer 200, respectively, and the opening on the rear side is used for receiving cool air, and the opening on the front side of the drawer 200 is used for guiding out air in the drawer 200.

As shown in fig. 1 to 3, a skirting area 101 is disposed on the front side of the bottom of the box 100, and a plurality of through holes are disposed on the skirting area 101, wherein a part of the through holes are air inlets 1011, and another part of the through holes are air outlets 1012. Specifically, the through hole in the left side of the skirting board region 101 is an air inlet 1011, and the through hole in the right side is an air outlet 1012.

Further, the air inlet 1011 is used for introducing external air into the press bin 103 (as shown in fig. 6) at the bottom of the rear of the box 100, and the air outlet 1012 is used for introducing the air in the press bin 103 to the outside, so as to realize heat dissipation of the refrigeration equipment. The press bin 103 is defined by the case 100, which will be described in detail later, and will not be described here.

It will be appreciated by those skilled in the art that since the cooling device of the present utility model can dissipate heat through the air inlet 1011 and the air outlet 1012 located at the front side thereof, the cooling device of the present utility model can be embedded in a space such as a cabinet, and thus the cooling device and the environment can be integrated into a whole, which is more attractive.

As shown in fig. 2, in some embodiments of the present utility model, the case 100 includes a base 110 and a bottom plate 120 at the bottom thereof, and the skirting area 101 is formed at the front side of the base 110. In other words, the air inlet 1011 and the air outlet 1012 are formed on the base 110. A base plate 120 is mounted to the bottom side of the base 110 for shielding the base 110. Further, the base 110 and the bottom plate 120 further define a press bin 103 (as shown in fig. 6), an air inlet channel 1041 (as shown in fig. 6), and an air outlet channel 1042 (as shown in fig. 6), wherein the air inlet channel 1041 is used for communicating the press bin 103 with the air inlet 1011, and the air outlet channel 1042 is used for communicating the press bin 103 with the air outlet 1012. The press bin 103, the air inlet passage 1041 and the air outlet passage 1042 will be described in detail later, and will not be described here again.

As shown in fig. 3 and 4, in some embodiments of the present utility model, the case 100 includes a liner 130 and an evaporator cover 140. The evaporator cover 140 is mounted to the inner bottom of the liner 130 such that the evaporator cover 140 and the liner 130 together define the refrigerated compartment 105 (as shown in fig. 9) such that the evaporator cover 140 forms the top wall of the refrigerated compartment 105. Further, the evaporator cover 140 is further provided with a return air inlet 141 in communication with the refrigeration compartment 105.

With continued reference to fig. 3 and 4, the cabinet 100 further includes a duct cover 150, the duct cover 150 being mounted to the rear side of the interior of the liner 130 such that the duct cover 150 and the liner 130 together define the air supply duct 106 (shown in fig. 9) in communication with the refrigeration compartment 105. Further, an air supply port 151 communicating with the air supply passage 106 is provided on the duct cover 150.

With continued reference to fig. 3 and 4, in some embodiments of the utility model, the liner 130, the evaporator cover 140, and the duct cover 150 further collectively define a storage compartment 102, the storage compartment 102 being in communication with the return air inlet 141 of the evaporator cover 140 and with the supply air outlet 151 of the duct cover 150.

In addition, in other embodiments of the present utility model, the air duct cover 150 may be disposed outside the liner 130 as desired by those skilled in the art, and thus the liner 130 and the evaporator cover 140 together define the storage compartment 102. Further, a drawer 200 is installed in the storage compartment 102.

Alternatively, one skilled in the art may omit at least one of the liner 130, the evaporator cover 140, and the duct cover 150 as needed, while ensuring that the cabinet 100 defines the storage compartment 102, the refrigeration compartment 105, and the air supply duct 106.

As shown in fig. 5, in some embodiments of the present utility model, the refrigeration appliance further includes a refrigeration system 300 to cool the storage compartment 102 by the refrigeration system 300. Specifically, the refrigeration system 300 includes a compressor 310, a condenser 320, a throttle and pressure reducing member 330, and an evaporator 340, which are connected end to end in sequence. The throttle reducing member 330 may be a capillary tube as shown in fig. 5, or an electronic expansion valve. Further, the compressor 310 is in fluid connection with the condenser 320 through a pipe, and the condenser 320 and the evaporator 340 are each directly connected with the throttle reducing member 330 or connected through a pipe. The evaporator 340 is connected to the compressor 310 through an air return pipe 350.

As shown in fig. 4 and 6, in some embodiments of the present utility model, a press bin 103, an air inlet passage 1041, and an air outlet passage 1042 are defined within the box 100. Specifically, the press housing 103, the air inlet passage 1041, and the air outlet passage 1042 are defined by the base 110 and the bottom plate 120. The press bin 103 includes a first side 1031 and a second side 1032, which are laterally distributed, the first side 1031 communicates with the air inlet channel 1041, and the second side 1032 communicates with the air outlet channel 1042. The air intake passage 1041 is located in front of the first side portion 1031, and the air outlet passage 1042 is located in front of the second side portion 1032.

As can be seen in fig. 6, the width of the second side 1032 is greater than the width of the first side 1031. Optionally, the ratio of the width of the second side 1032 to the width of the first side 1031 ranges from 1.5 to 2. For example, the ratio of the width of the second side 1032 to the width of the first side 1031 is 1.5, 1.6, 1.8, 2, etc.

As can also be seen in fig. 6, the air inlet channel 1041 is equally wide as the first side 1031, the air outlet channel 1042 is equally wide as the second side 1032, and the air inlet channel 1041 and the air outlet channel 1042 are generally parallel.

With continued reference to fig. 6, in some embodiments of the utility model, the compressor 310 is disposed within the second side 1032 and the condenser 320 is disposed within the intake passage 1041.

Further, one skilled in the art may also arrange the condenser 320 within the first side 1031 as desired. Alternatively, a portion of the condenser 320 is disposed within the first side 1031 and another portion of the condenser 320 is disposed within the intake passage 1041.

As will be appreciated by those skilled in the art, since the structure of the condenser 320 is relatively simple and may be configured in any shape according to actual needs, the heights of the first side 1031 and the air intake passage 1041 can be set sufficiently low by configuring the condenser 320 in a flat shape and distributing the condenser 320 in at least one of the first side 1031 and the air intake passage 1041 as needed.

With continued reference to fig. 6, in some embodiments of the utility model, the refrigeration apparatus further includes a heat dissipation blower 410, the heat dissipation blower 410 being disposed within the second side 1032 and on a side of the compressor 310 proximate to the first side 1031. In addition, one skilled in the art may also place the heat dissipation blower 410 at any other feasible location, for example, place the heat dissipation blower 410 in the first side 1031 or on a side of the second side 1032 away from the first side 1031, as desired.

As will be appreciated by those skilled in the art, when the heat dissipation fan 410 is operated, the air from the outside can be driven to enter the air inlet channel 1041 from the air inlet 1011, further flow through the press cabin 103 and the air outlet channel 1042, and flow to the outside again from the air outlet 1012. As the air flows through the compressor 310 and the condenser 320, the heat of the compressor 310 and the condenser 320 is absorbed, thereby cooling the compressor 310 and the condenser 320.

In the present utility model, the skilled person can set the heat radiation fans 410 to any feasible number, for example, one, two, three, etc., as required.

With continued reference to fig. 6, in some embodiments of the utility model, the refrigeration apparatus further includes an evaporation pan 500. The evaporation pan 500 is disposed in the air outlet passage 1042, and a pipe connected in series between the compressor 310 and the throttle reducing member 330 is partially disposed in the evaporation pan 500 to heat water in the evaporation pan 500. Optionally, a conduit in series between the compressor 310 and the condenser 320 is partially disposed within the evaporation pan 500 to heat the water within the evaporation pan 500. Meanwhile, the high temperature air heated by the compressor 310 and the condenser 320 heats the water in the evaporation pan 500 while passing through the evaporation pan 500, thereby promoting the evaporation of the water in the evaporation pan 500.

With continued reference to fig. 6, in some embodiments of the utility model, the refrigeration appliance further includes an electrically controlled cassette 600, the electrically controlled cassette 600 being disposed within the first side 1031.

Furthermore, those skilled in the art may also arrange the pod 600 in any other feasible location, such as, for example, arranging the pod 600 in the intake passage 1041, as desired.

The press housing 103, the air intake passage 1041, and the air outlet passage 1042 are further described below with reference to fig. 7 and 8 in combination with the base 110.

As shown in fig. 7 and 8, in some embodiments of the present utility model, the height of the first side 1031 is lower than the height of the second side 1032, and the height of the air intake passage 1041 is lower than the height of the air outlet passage 1042, so that the evaporator 340 is disposed above the first side 1031 and the air intake passage 1041, thereby lowering the height of the evaporator 340.

As will be appreciated by those skilled in the art, when the height of the evaporator 340 is reduced, the bottom wall of the compartment 102 can be lowered accordingly, thereby increasing the volume of the compartment 102 and thus the volume utilization of the refrigeration appliance.

It should be noted that the height of the portion of the air outlet channel 1042 near the air inlet channel 1041 may be equal to the height of the air inlet channel 1041.

With continued reference to fig. 7 and 8, the top wall of the first side 1031 slopes downwardly from rear to front. The rear portion of the top wall of the second side 1032 is disposed horizontally and the front portion of the top wall of the second side 1032 is inclined downwardly from rear to front.

Optionally, the ratio of the average height of the second side 1032 to the average height of the first side 1031 ranges from 1.5 to 3. For example, the ratio of the average height of the second side 1032 to the average height of the first side 1031 may take on values of 1.5, 1.6, 2, 2.5, 3, etc. Preferably, the ratio of the average height of the second side 1032 to the average height of the first side 1031 is 2.

Further alternatively, the ratio of the height of the rear portion of the top wall of the second side 1032 to the average height of the first side 1031 can range from 1.5 to 3. For example, the ratio of the height of the rear portion of the top wall of the second side 1032 to the average height of the first side 1031 may take on values of 1.5, 1.6, 2, 2.5, 3, etc. Preferably, the ratio of the height of the rear portion of the top wall of the second side 1032 to the average height of the first side 1031 is 2.

With continued reference to fig. 7 and 8, the base 110 includes a partition 111, the partition 111 being used to partition the press bin 103 into a first side 1031 and a second side 1032. The partition 111 is provided with an air vent 1111 to communicate the first side 1031 with the second side 1032 through the air vent 1111. Optionally, mounting holes (not shown) for mounting the heat dissipation fan 410 are further provided on the partition 111, so that the heat dissipation fan 410 is fixed to the partition 111.

As can also be seen in fig. 7 and 8, the partition 111 extends from the rear end of the base 110 to the front end of the base 110, such that the partition 111 also serves to separate the air intake passage 1041 from the air outlet passage 1042.

As can be seen in fig. 7, in some embodiments of the present utility model, a plurality of heat dissipation holes (not labeled in the drawing) are further provided on the base plate 120, and the heat dissipation holes are located below the compressor 310, for dissipating heat from the compressor 310. In addition, the person skilled in the art can omit the arrangement of the heat dissipation holes as required.

In addition, in other embodiments of the present utility model, those skilled in the art may omit the air inlet 1011, the air outlet 1012, the air inlet channel 1041 and the air outlet channel 1042 for the refrigerating device which does not need to be embedded, and set the air inlet 1011 at the side of the first side 1031 away from the second side 1032, and set the air outlet 1012 at the side of the second side 1032 away from the first side 1031. Further, the length of the first side 1031 in the front-rear direction may be appropriately extended so as to allow enough space in the horizontal direction for disposing the condenser 320, preventing the first side 1031 from being excessively high.

As shown in fig. 4 and 9, a refrigerating compartment 105 is defined between the liner 130 and the evaporator cover 140, and an air supply passage 106 is defined between the liner 130 and the duct cover 150, and the air supply passage 106 communicates with the refrigerating compartment 105. The evaporator cover 140 has a return air inlet 141 in front thereof and communicating with the refrigerating compartment 105, and the air duct cover 150 has an air outlet 151 in communication with the air supply duct 106.

Preferably, in some embodiments of the present utility model, the plurality of air outlets 151 is provided such that each drawer 200 corresponds to at least one air outlet 151, respectively, such that the drawers 200 receive cool air blown out from the air outlets 151.

As shown in fig. 9, the refrigerating compartment 105 is disposed above the air intake passage 1041 to lower the height of the bottom wall of the refrigerating compartment 105, thereby lowering the overall height of the refrigerating compartment 105.

Those skilled in the art will appreciate that the temperature of the air in the air intake passage 1041 is relatively low as compared to the temperature of the air in the air outlet passage 1042, since the air in the air intake passage 1041 has not absorbed the heat of the compressor 310 and the condenser 320, or only absorbs a portion of the heat of the condenser 320. Therefore, the refrigerating compartment 105 is disposed directly above the air intake passage 1041 such that the refrigerating compartment 105 and the air outlet passage 1042 do not overlap or overlap only in a small portion in the vertical direction; compared with the prior art that the refrigerating compartment 105 is arranged above the air inlet channel 1041 and the air outlet channel 1042, the temperature difference between the refrigerating compartment 105 and the air inlet channel 1041 is smaller, and the leakage of the cold at the bottom side is less, so that the heat insulation layer 160 between the refrigerating compartment 105 and the air inlet channel 1041 is relatively thinner, and the overall height of the refrigerating compartment 105 is further reduced.

With continued reference to fig. 9, an evaporator 340 is disposed within the refrigerated compartment 105 and is located on the rear side of the return air inlet 141. Preferably, the evaporator 340 is of a generally flat configuration, and the evaporator 340 is disposed in the refrigerated compartment 105 in a horizontal position to reduce the height of the evaporator 340 and thus the overall height of the refrigerated compartment 105.

With continued reference to fig. 9, in some embodiments of the utility model, the refrigeration apparatus further includes a refrigeration fan 420. The refrigeration fan 420 is disposed within the refrigeration compartment 105. Preferably, the cooling fan 420 is disposed at the rear side of the evaporator 340. Alternatively, one skilled in the art may also dispose the refrigeration fan 420 between the return air inlet 141 and the evaporator 340, or dispose the refrigeration fan 420 within the supply air duct 106, as desired.

As can be seen from fig. 9, the cooling fans 420 are arranged obliquely in the front-rear direction to reduce the height of the cooling fans 420, and the air outlet direction of the cooling fans 420 is directed upwards as much as possible to reduce the wind resistance between the cooling fans 420 and the inlet of the air supply passage 106.

The cooling fan 420 may be an axial flow fan, a centrifugal fan, or a cross flow fan.

Further, although not shown in the drawings, in some embodiments of the present utility model, the number of the cooling fans 420 is at least two, and the at least two cooling fans 420 are distributed in the left-right direction, so that the height of the cooling fans 420 as a whole is small while ensuring that the cooling fans 420 provide sufficient wind power for the cooling device, thereby avoiding the storage compartment 102 from being excessively raised, and further improving the space utilization rate of the cooling device.

Still further, although not shown, in some embodiments of the utility model, the floor of the refrigerated compartment 105 is configured to be sloped upward from front to back in the region carrying the refrigeration fan 420. And the maximum height of the region is lower than the height of the top surface of the second side 1032 so that the maximum height of the bottom surface of the refrigerating fan 420 is lower than the height of the top surface of the second side 1032. In particular, the maximum height of the region is lower than the height of the rear portion of the second side top wall.

As shown in fig. 4, 10 to 12, the evaporator cover 140 is equal in height in the left-right direction, and thus the insulation layer 160 between the air outlet channel 1042 and the liner 130 is higher, so as to avoid the cold leakage of the storage compartment 102 into the air outlet channel 1042. Meanwhile, the muffler 350 of the refrigeration system 300 is disposed in the insulation 160 between the air outlet passage 1042 and the storage compartment 102.

As shown in fig. 9 and 12, a drain hole 13212 is provided in the bottom wall of the refrigeration compartment 105, and the drain hole 13212 is located below the evaporator 340. The bottom wall of the refrigeration compartment 105 slopes downward from front to rear from the front end of the evaporator 340 to the drain hole 13212; the bottom wall of the refrigeration compartment 105 slopes downward from rear to front from the rear end of the evaporator 340 to the drain hole 13212; the bottom wall of the refrigeration compartment 105 slopes downward from left to right from the left end of the evaporator 340 to the drain hole 13212; the bottom wall of the refrigerated compartment 105 slopes downward from right to left from the right end of the evaporator 340 to the drain hole 13212 so that the defrost water of the evaporator 340 can flow all along the bottom wall of the refrigerated compartment 105 to the drain hole 13212.

As can be seen from fig. 12, although the portion of the air outlet channel 1042 near the air inlet channel 1041 is at the same height as the air inlet channel 1041, and the air outlet channel 1042 overlaps the refrigerating compartment 105 partially in the vertical direction; however, since the bottom wall of the refrigerating compartment 105 is inclined downward from right to left from the right end of the evaporator 340 to the drain hole 13212, the thickness of the insulating layer 160 between the air outlet passage 1042 and the refrigerating compartment 105 is greater than the thickness of the insulating layer 160 between the air inlet passage 1041 and the refrigerating compartment 105, and the refrigerating compartment 105 has less cold exposure to the air outlet passage 1042.

As shown in fig. 11 and 12, in some embodiments of the present utility model, the refrigerating apparatus further includes a drain pipe 170, one end of the drain pipe 170 communicates with the drain hole 13212, and the other end of the drain pipe 170 extends to the evaporating dish 500. Preferably, a water sealing ring 510 is provided in the evaporation pan 500, and the water sealing ring 510 extends upward from the inner bottom surface of the evaporation pan 500. The other end of the drain pipe 170 extends into the water sealing ring 510, and the drain pipe 170 has a gap with the water sealing ring 510 in a radial direction so that water in the drain pipe 170 flows into the evaporation pan 500 through the gap.

It will be appreciated by those skilled in the art that the combination of the drain pipe 170 and the water seal ring 510 can form a communicating vessel structure to seal the water outlet end of the drain pipe 170, thereby preventing hot air in the air outlet channel 1042 from entering the refrigerating compartment 105 via the drain pipe 170 and affecting the refrigerating effect of the evaporator 340.

As shown in fig. 13 and 14, in some embodiments of the present utility model, the liner 130 includes a liner body 131 and a sink 132 at the bottom of the liner body 131, the sink 132 being covered by an evaporator cover plate 140 to form the refrigerated compartment 105 and thus the evaporator cover plate 140 forming the bottom wall of the refrigerated compartment 105. Further, sink trough 132 includes a front side 1321 and a rear side 1322. The bottom wall of the front side 1321 is disposed horizontally, and the bottom wall of the rear side 1322 is inclined upward from front to rear; the front side 1321 is used for arranging the evaporator 340 and the rear side 1322 is used for arranging the cooling fan 420.

Further, the width of the front side 1321 is greater than half of the width of the cavity of the container 131, and the width of the rear side 1322 is smaller than half of the width of the cavity of the container 131, so that the sinking groove 132 is located as completely as possible directly above the air inlet 1041 while the front side 1321 can hold the evaporator 340, and particularly, the rear side 1322 of the sinking groove 132 is located completely directly above the air inlet 1041, so as to prevent the cooling compartment 105 from leaking cold to the air inlet 1041.

As shown in fig. 13 to 15, a drain hole 13212 (i.e., a drain hole 13212 of the refrigerating compartment 105) is provided in the bottom wall of the front side portion 1321, and the drain hole 13212 is located on a side of the front side portion 1321 near the container body 131 where the sink 132 is not provided, so that the drain hole 13212 is laterally closer to the evaporating dish 500. The middle region 13211 of the front side 1321 is configured to support the evaporator 340, and the height of the middle region 13211 gradually decreases toward the drain hole 13212, so that the middle region 13211 forms a funnel shape.

As shown in fig. 13 and 14, the inner bottom surface of the bladder 131 is at the left and right sides of the front side 1321 and is equally high in the left-right direction to carry the evaporator cover 140 so that the evaporator cover 140 shields the front side 1321. Further, the inner bottom surface of the container body 131 is provided with cover flanges 133 at left and right sides of the rear side portion 1322, respectively, and the cover flanges 133 are used to fix the evaporator cover 140 so that the evaporator cover 140 shields the rear side portion 1322.

As can be seen from fig. 13 and 14, the cover flange 133 at the rear of the inner bottom surface of the container body 131 protrudes from the inner bottom surface of the container body 131 so that the evaporator cover 140 having the same height in the lateral direction is better fitted to the cover flange 133. At the same time, a gap for communicating the cooling compartment 105 with the air supply duct 106 can be formed between the right side of the rear portion of the inner bottom surface of the liner 131 and the evaporator cover 140.

As shown in fig. 13 to 15, the liner 130 further includes an air duct flange 134 provided on a rear sidewall of the liner body 131, and the air duct flange 134 is used for mounting an air duct cover 150, so that an air supply passage 106 communicating with the sink groove 132 is defined between the air duct cover 150 and the liner body 131.

Based on the foregoing description, it can be appreciated by those skilled in the art that the present utility model effectively reduces the overall height of the press bin 103 and the refrigeration compartment 105 by arranging the press bin 103 to have the first side 1031 and the second side 1032 laterally distributed, with the first side 1031 having a height lower than the second side 1032, and with the refrigeration compartment 105 formed above the first side 1031, and with the compressor 310 disposed within the second side 1032, thereby improving the space utilization of the refrigeration equipment.

Further, by providing the air inlet passage 1041 at the front side of the first side 1031 and the air outlet passage 1042 at the front side of the second side 1032, the condenser 320 can be disposed within the air inlet passage 1041, further lowering the height of the first side 1031. By arranging the refrigerated compartment 105 above the first side 1031 and the air inlet duct 1041, the height of the bottom wall of the refrigerated compartment 105 is effectively reduced compared to arranging the refrigerated compartment 105 above the entire press bin 103 and the air inlet duct 1041 and the air outlet duct 1042 in the prior art, thereby reducing the overall height of the refrigerated compartment 105, leaving more space for the storage compartment 102 and improving the space utilization of the refrigeration device.

Thus far, the technical solution of the present utility model has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present utility model is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present utility model, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present utility model will fall within the protection scope of the present utility model.
