Detailed Description

The present invention first provides a refrigerator, fig. 1 is a schematic structural view of the refrigerator according to one embodiment of the present invention, fig. 2 is a partially structural exploded view of the refrigerator according to one embodiment of the present invention, fig. 3 is a schematic sectional view taken along a section line A-A in 1, and fig. 4 is a schematic sectional view taken along a section line B-B in 1. Referring to fig. 1 to 4, the refrigerator 1 of the present invention includes a cabinet 10, a first evaporator 21, and a second evaporator 22.

The case 10 defines therein a first storage compartment 111 and a second storage compartment 121 that are disposed side by side with a spacing in the lateral direction of the case 10, and a first cooling compartment 112 and a second cooling compartment 122 that are disposed side by side with a spacing in the lateral direction of the case 10, the first cooling compartment 112 and the second cooling compartment 122 being located adjacently below the first storage compartment 111 and the second storage compartment 121, respectively. That is, the first cooling chamber 112 and the second cooling chamber 122 are both cooling chambers that are bottomed in the case 10.

The first evaporator 21 and the second evaporator 22 are disposed in the first cooling chamber 112 and the second cooling chamber 122, respectively, and configured to provide cooling capacity to the first inter-storage chamber 111 and the second inter-storage chamber 121, respectively. That is, the first evaporator 21 and the second evaporator 22 are both evaporators which are bottomed in the case 10.

The first inter-storage chamber 111 communicates with the first cooling chamber 112 through a first air supply port 711 located at the rear side of the first inter-storage chamber 111 and a first air return port located at the front side of the bottom of the case 10, so as to allow cooling air in the first cooling chamber 112 to flow into the first inter-storage chamber 111 through the first air supply port 711, and allow return air in the first inter-storage chamber 111 to flow into the first cooling chamber 112 through the first air return port. Similarly, the second storage compartment 121 is communicated with the second cooling compartment 122 through a second air supply opening at the rear side of the second storage compartment 121 and a second air return opening at the front side of the bottom of the case 10, so as to allow cooling air in the second cooling compartment 122 to flow into the second storage compartment 121 through the second air supply opening and allow return air in the second storage compartment 121 to flow into the second cooling compartment 122 through the second air return opening.

The refrigerator comprises two bottom-mounted cooling chambers, each cooling chamber is internally provided with an evaporator for providing cold energy for the storage chamber above the cooling chamber, namely the refrigerator is provided with two bottom-mounted evaporators, so that the volume of the storage chamber of the refrigerator with larger width can be increased as much as possible. And each storage compartment is communicated with the cooling chamber below the storage compartment through the air supply opening at the rear side of the storage compartment and the air return opening at the front side of the bottom of the box body. Therefore, the cooling air flow in the cooling chamber can be blown into the corresponding storage compartment from the air supply opening to the front, the cooling air flow naturally sinks in the storage compartment from top to bottom and from front to back, and the air flow flowing through almost the whole storage compartment forms return air flow at the front side of the bottom of the storage compartment and returns to the cooling chamber through the return air opening at the front side of the bottom of the box body. Therefore, the cooling air flow sent out by the air supply outlet is approximately parallel, and the direct blowing of the air supply outlet is avoided, so that the temperature of the storage compartment is more uniform.

Specifically, the first storage compartment 111 and the first cooling compartment 112 may be defined inside the first liner 11 and located at upper and lower portions of the first liner 11, respectively. The second storage compartment 121 and the second cooling compartment 122 may be defined inside the second liner 12 and located at upper and lower portions of the second liner 12, respectively. The first and second inner containers 11 and 12 are independent of each other, and thus, the first and second inter-storage compartments 111 and 121 are independent of each other, and the first and second cooling compartments 112 and 122 are independent of each other.

Specifically, the rear side of the first storage compartment 111 is provided with a first air duct assembly 71, the interior of which defines a first air supply duct communicating with the first cooling compartment 112, and a first air supply port 711 is provided at the front side of the first air duct assembly 71. The second air duct assembly 72 is disposed at the rear side of the second storage compartment 121, a second air supply duct communicating with the second cooling compartment 122 is defined in the second air duct assembly 72, and a second air supply port 721 is opened at the front side of the second air duct assembly 72.

Further, the electrically controlled terminals and the refrigerant connections associated with the first storage compartment 11 are located on the lateral sides of the first air duct assembly 71, respectively, and the electrically controlled terminals and the refrigerant connections associated with the second storage compartment 12 are located on the lateral sides of the second air duct assembly 72, respectively.

Specifically, the first evaporator 21 and the second evaporator 22 are each inclined upward from front to back. The first cooling chamber 112 is further provided with a first air blower 23 located at the rear side of the first evaporator 21, and the second cooling chamber 122 is further provided with a second air blower 24 located at the rear side of the second evaporator 22.

In some embodiments, a third storage compartment 171 located above the first storage compartment 111 and the second storage compartment 121, and a third cooling compartment 172 located at a rear side of the third storage compartment 171 are also defined in the case 10. The refrigerator 1 further includes a third evaporator 25 disposed in the third cooling chamber 172, the third evaporator 25 being configured to provide cooling capacity to the third storage compartment 171.

Specifically, the first storage compartment 111 and the second storage compartment 121 may be a freezing compartment and a temperature changing compartment, respectively. Specifically, the temperature of the first storage compartment 111 is typically between-24 ℃ and-14 ℃, and the temperature of the second storage compartment 111 can be optionally adjusted to between-24 ℃ and-8 ℃. The third storage compartment 171 may be a refrigerated compartment in which the temperature is typically 2-10 c.

In some embodiments, the first storage compartment 111 and the first cooling compartment 112 are separated by a first cover plate 31, and the second storage compartment 121 and the second cooling compartment 122 are separated by a second cover plate 32. Referring to a partially exploded view of a refrigerator according to an embodiment of the present invention shown in fig. 5, the first cover plate 31 includes a transverse section 311 extending from rear to front and a vertical section 312 extending obliquely forward from top to bottom from a front end of the transverse section 311. The second cover plate 32 includes a transverse section 321 extending from rear to front and a vertical section 322 extending obliquely forward from top to bottom from the front end of the transverse section 321. The first cooling compartment 112 is located on the rear side of the vertical section 312 of the first cover plate 31, and the first return air inlet includes a first rear return air inlet 3121 that is open on the vertical section of the first cover plate 31. The second cooling compartment 122 is located on the rear side of the vertical section 322 of the second cover plate 32, and the second return air inlet includes a second rear return air inlet 3221 that is open on the vertical section 322 of the second cover plate 32. Thereby, the condensed water of the first back return air inlet 3121 flows timely along the vertical section 312 to the bottom of the first cooling chamber 112 under the action of self gravity and finally flows to a water receiving tray or other water collecting structure at the bottom of the first cooling chamber 112; the condensed water at the second back return air inlet 3221 flows timely along the vertical section 322 to the bottom of the second cooling chamber 122 under the action of self gravity, and finally flows to a water receiving tray or other water collecting structure at the bottom of the second cooling chamber 122. Therefore, condensed water is not easily collected at the first and second rear return openings 3121 and 3221 to generate ice or frost.

The existing refrigerator with the bottom evaporator and the bottom cooling chamber also adopts the cover plate to separate the cooling chamber from the storage chamber, however, the cover plate in the prior art only has a transverse section and no vertical section, and an air return cover is arranged on the front side of the cover plate to isolate the cooling chamber from the sight of a user. When condensate water is generated in the storage room, the condensate water drops on the cover plate or the return air cover. Condensed water which is dripped on the cover plate is dripped into the cooling chamber from the assembly gap between the cover plate and the return air cover, so that the condensed water is easy to drip on the evaporator to cause serious frosting of the evaporator; the condensed water which drops on the return air cover directly flows out of the box body, so that the use experience of a user is affected.

The cover plate of the invention is provided with the transverse section and the vertical section, which are equivalent to the smooth connection of the transverse section and the vertical section, so that condensed water dripping in the storage room above the transverse section can directly flow to the bottom wall of the cooling room along the inclined vertical section, and the problem that the use experience of a user is influenced or the evaporator is seriously frosted due to dripping on the evaporator can not be caused by flowing out of the box body 10.

Further, the number of the first back air return openings 3121 and the second back air return openings 3221 is plural, the plural first back air return openings 3121 are arranged at intervals in the lateral direction, the plural second back air return openings 3221 are arranged at intervals in the lateral direction, and each of the first back air return openings 3121 and each of the second back air return openings 3221 is a vertically extending strip-shaped air opening. That is, the first grill 3122 for separating the adjacent two first rear return openings 3121 each extend vertically in line with the flow trend of the condensate on the vertical section 312; the second bars 3222 for separating two adjacent second rear return air inlets 3221 each extend vertically in accordance with the flow trend of condensate water on the vertical section 322. Therefore, the condensed water hardly stays on the first and second grills 3122 and 3222, which is beneficial to the condensed water to flow downwards faster along the first and second grills 3122 and 3222, improves the speed of the condensed water flowing down, and more effectively avoids the icing or frosting caused by the difficult accumulation of the condensed water at the first and second back return air inlets 3121 and 3221.

In particular, the width of the first and second back return air inlets 3121 and 3221 is preferably 5mm or less to prevent the child user from extending his fingers.

In some embodiments, the refrigerator 1 further includes a first return air cover 41 and a second return air cover 42. The first return air cover 41 is disposed at the front side of the first cover plate 31 and includes a first transverse cover plate 411 extending from the rear to the front by the transverse section 311 of the first cover plate 31 and a first vertical cover plate 412 extending downward by the front end of the first transverse cover plate 411. The second return air cover 42 is disposed at the front side of the second cover plate 32 and includes a second transverse cover plate 421 extending from the rear to the front by the transverse section 321 of the second cover plate 32 and a second vertical cover plate 422 extending downward by the front end of the second transverse cover plate 421. The first return air inlet further comprises a first front return air inlet 4121 formed in the first vertical housing plate 412, and the second return air inlet further comprises a second front return air inlet 4221 formed in the second vertical housing plate 422. That is, the return air flow in the first storage compartment 111 flows into the first cooling compartment 112 after passing through the first front return air inlet 4121 and the first rear return air inlet 3121 in sequence; the return air flow in the second storage compartment 121 flows through the second front return air inlet 4221 and the second rear return air inlet 3221 in sequence, and then flows into the second cooling compartment 122.

Further, the first vertical cover plate 412 is spaced from the vertical section 312 of the first cover plate 31 to define a first return air space 51 between the first return air cover 41, the vertical section 312 of the first cover plate 31, and the bottom wall and the two lateral side walls of the first liner 11. The second vertical cover plate 422 is spaced from the vertical section 322 of the second cover plate 32 to define a second return air space 52 between the second return air hood 42, the vertical section 322 of the second cover plate 32, and the bottom wall and two lateral side walls of the second liner 12.

It will be appreciated that the flow of return air from the first compartment 111 to the first cooling compartment 112 and the flow of air from the second compartment 121 to the second cooling compartment 122 must be subjected to a reversing process. The first return air space 51 and the second return air space 52 provide buffer spaces for reversing and stabilizing the return air flow, and the like, so that the flow resistance is small, the return air flow flows through the return air space with small flow resistance and then flows to the cooling chamber, and the great influence of reversing on the flow velocity of the return air flow is avoided. In addition, the moisture in the return air flow can be condensed in advance at the front return air inlet, the return air space and the rear return air inlet, so that the moisture condensed on the evaporator is reduced, and the frosting condition of the evaporator is relieved.

It can be understood that, for the refrigerator 1 with smaller size in the depth direction, the purpose of isolating the storage compartment from the cooling compartment and communicating the storage compartment and the cooling compartment through the air return opening can be satisfied by directly using the cover plate, and the air return cover is not required to be arranged. For the refrigerator 1 with larger size in the depth direction, a return air cover is also required to be arranged at the front side of the cover plate, and the purposes of isolating the storage compartment 111 from the cooling compartment 112 and enabling the storage compartment and the cooling compartment to be communicated through the return air inlet can be also met. Therefore, the cover plate has strong universality, is suitable for refrigerators with different sizes, and saves the die cost.

In addition, the present invention has the function of decorating the front side of the cover plate by providing the return air cover, and can unify the front appearances of the first storage compartment 111 and the second storage compartment 121, so that even if the structures of the first cover plate 31 and the second cover plate 32 are different, or the depth sizes of the first cooling compartment 112 and the second cooling compartment 122 are different due to the sizes of the first evaporator 21 and the second evaporator 22 or other reasons, the first storage compartment 111 and the second storage compartment 121 can be ensured to have uniform front appearances.

Further, the number of the first front air return openings 4121 and the number of the second front air return openings 4221 are all plural, the plural first front air return openings 4121 are arranged at intervals in the up-down direction, and the plural second front air return openings 4221 are arranged at intervals in the up-down direction. Each of the first front return air inlet 4121 and each of the second front return air inlet 4221 are laterally extending strip-shaped air inlets.

In some embodiments, the front side of the vertical section 312 of the first cover plate 31 is provided with a first flow guiding rib 3123 protruding forward, and the front side of the vertical section 322 of the second cover plate 32 is provided with a second flow guiding rib 3223 protruding forward. The first diversion ribs 3123 extend obliquely downward or bend downward from the lateral middle of the vertical section 312 in which they are located to the lateral sides of the vertical section 312; the second air guide rib 3223 extends obliquely downward or bends downward from the lateral middle of the vertical section 322 where it is located to the lateral sides of the vertical section 322.

When the condensate water flowing from top to bottom on the vertical section 312 encounters the first diversion rib 3123, the condensate water can flow to two lateral sides of the vertical section 312 along the first diversion rib 3123 and then flow to the bottom wall of the first liner 11, and the condensate water can not flow through the area of the first back return air inlet 3121 below the first diversion rib 3123, so as to reduce the amount of condensate water attached to the first back return air inlet 3121, thereby reducing the amount of ice or frost generated at the first back return air inlet 3121, and even avoiding the problem of icing or frosting at the first back return air inlet 3121. In addition, the first diversion ribs 3123 extend downwards from the middle to the two sides, which is not only beneficial to the rapid flow of the condensed water, but also ensures that at least the upper and lower parts of most sections of the first diversion ribs 3123 are located in the air flow path of the first back air inlet 3121, i.e. ensures that at least the upper and lower parts of most sections of the first diversion ribs 3123 have the return air flow passing through, thereby preventing the local large-area frosting at the first diversion ribs 3123. In the same way, the problem of icing or frosting at the second rear air return opening 3221 can be prevented, and local large-area frosting at the second guide rib 3223 is prevented, and the details are not repeated here.

Further, the middle portion of the first flow-guiding rib 3123 is adjacent to the top of the vertical section 312, and both end portions of the first flow-guiding rib 3123 are adjacent to the middle portion of the vertical section 312 in the vertical direction, so that the first flow-guiding rib 3123 is entirely at the upper portion of the vertical section 312. On the one hand, the flow path of the condensed water on the first grill 3122 is shortened as much as possible, thereby reducing the amount of condensed water attached at the first rear return air inlet 3121 as much as possible; on the other hand, the first diversion ribs 3123 have enough inclination or curvature so that the condensed water flows down from the first diversion ribs 3123 as soon as possible, thereby avoiding the problem of frosting or icing at the first diversion ribs 3123. Likewise, the middle portion of the second flow guiding rib 3223 is adjacent to the top portion of the vertical section 322, and both end portions of the second flow guiding rib 3223 are adjacent to the middle portion of the vertical section 322 in the vertical direction, so that the second flow guiding rib 3223 is integrally located at the upper portion of the vertical section 322, and the technical effect thereof is the same as that of the first flow guiding rib 3123, which is not described herein again.

Fig. 6 is a schematic structural view of a first bladder and a second bladder according to one embodiment of the present invention. In some embodiments, a first water receiving tray 113 is formed at the bottom of the first cooling chamber 112, that is, a first water receiving tray 113 is formed at the bottom wall of the first liner 11 below the first evaporator 21, the first water receiving tray 113 is formed by enclosing a plurality of first inclined portions, the bottoms of the plurality of first inclined portions intersect, and a first water outlet 114 is formed at the intersection. The bottom of the second cooling chamber 122 is formed with a second water receiving tray 123, that is, the bottom wall of the second liner 12 below the second evaporator 22 forms the second water receiving tray 123, the second water receiving tray 123 is formed by enclosing a plurality of second inclined portions, the bottoms of the second inclined portions intersect, and a second water outlet 124 is formed at the intersection.

The refrigerator cabinet 10 of the present invention defines two cooling chambers disposed at a lateral interval to provide cooling capacity to the two bottom storage compartments, respectively, and each cooling chamber of the present invention is greatly reduced in width in the lateral direction compared to one cooling chamber. And the water receiving tray at the bottom of each cooling chamber is formed by encircling a plurality of inclined parts, and a water outlet is formed at the intersection of the bottoms of the inclined parts. Therefore, under the same height limitation, the inclination degree of the plurality of inclined parts for forming the water receiving tray is higher, so that condensed water or defrosting water generated by the evaporator can flow to the water outlet faster along the inclined parts, and the problem of frost blockage generated by evaporation is avoided.

Further, the plurality of first inclined portions include a first rear inclined portion inclined downward from the rear toward the front, a first front inclined portion inclined downward from the front toward the rear, and a first left inclined portion and a first right inclined portion inclined downward from the left and right sides toward the lateral middle, respectively. The plurality of second inclined portions include a second rear inclined portion inclined downward from the rear toward the front, a second front inclined portion inclined downward from the front toward the rear, and a second left inclined portion and a second right inclined portion inclined downward from the left and right sides toward the lateral middle, respectively. That is, the first water pan 113 and the second water pan 123 are funnel-like members formed by gathering and polymerizing four inclined portions from top to bottom in front, rear, left, and right directions, and on the one hand, condensed water generated by the first evaporator 21 and dropped at an arbitrary position of the first water pan 113 can be effectively collected to the first drain port 114, and condensed water generated by the second evaporator 22 and dropped at an arbitrary position of the second water pan 123 can be collected to the second drain port 124; on the other hand, compared with the reverse conical water pan, the water pan formed by surrounding the inclined parts in four directions is more beneficial to the installation and support of the evaporator.

Specifically, the two inclined portions on the left side and the right side of the first water receiving tray 113 and the second water receiving tray 123 are bent and extended, and the inclination degrees of the two inclined portions are gradually increased in the drain port direction toward the bottom of the first water receiving tray and the second water receiving tray, so that the flow speed of condensed water far away from the drain port area is delayed, the speed of condensed water close to the drain port area flowing to the drain port is increased, condensed water is prevented from being gathered at the drain port, and the drainage efficiency of the condensed water is further improved. The two inclined portions of the first and second water receiving trays 113 and 123 in both the front and rear directions may extend straight or may extend in a curved manner.

In some embodiments, both the first and second ribs 3123, 3223 extend obliquely upward back and forth. Therefore, the condensed water on the first guide rib 3123 and the second guide rib 3223 have a tendency to flow to both lateral sides and backward, and even when the amount of condensed water on the first guide rib 3123 and the second guide rib 3223 is large, the condensed water does not overflow the first guide rib 3123 and the second guide rib 3223 forward, but flows along the first guide rib 3123 and the second guide rib 3223 or the first grid and the second grid to the bottom wall of the first liner 11 located at the rear side of the vertical section 312 and the bottom wall of the second liner 12 located at the rear side of the vertical section 322, that is, flows to the first water receiving disc 113 and the second water receiving disc 123, so that the condensed water is conveniently discharged through the water outlet at the bottom of the water receiving disc.

Specifically, the included angle between the first and second flow-guiding ribs 3123 and 3223 and the horizontal plane is preferably greater than 7 °.

In some embodiments, the first cover plate 31 and the first liner 11, and the second cover plate 32 and the second liner 12 are connected by clamping. Even if the overlap joint surface of the cover plate and the liner is narrower, even the overlap joint surface is cancelled, the assembly between the cover plate and the liner is not affected. Therefore, the fixing mode between the cover plate and the liner is more reasonable, and the refrigerator with the double bottom evaporators and the double liners is more suitable for refrigerators.

Further, the first cover plate 31 includes two first side flanges 313 for forming two lateral sides thereof, and the two first side flanges 311 are respectively overlapped on the two first ribs 115 located at two lateral sides of the first liner 11, so as to support the first cover plate 31 in an auxiliary manner through the first ribs 115. The second cover plate 32 includes two second side flanges 323 for forming both lateral sides thereof, and the two second side flanges 323 are respectively overlapped on the two second container ribs 125 located on both lateral sides of the second container 12, so as to support the second cover plate 32 in an auxiliary manner through the second container ribs 125. The first and second ribs 115, 125 have inclined sections extending obliquely, and the first and second side flanges 313, 323 also have mating inclined sections to increase the size of the ribs and side flanges for facilitating the auxiliary attachment of fasteners thereto.

In some embodiments, the cabinet 10 further defines a compressor compartment 13 at its bottom, a dryer assembly 60, a first drain pipe 81, a second drain pipe 82, and an evaporation pan 90. The refrigerator 1 further includes a compressor 51 and a heat radiation fan 52 disposed in the compressor compartment 13. The air duct assembly 60 is used for installing the heat dissipation fan 52, and the air duct assembly 60 extends along the depth direction of the box body 10 to divide the space in the compressor bin 13 into two sub-spaces which are laterally arranged side by side, and the compressor 51 is located in one of the sub-spaces. The first and second drain pipes 81 and 82 extend from the first and second cooling chambers 112 and 122, respectively, to two subspaces of the compressor compartment 13.

Fig. 7 is a schematic structural view of a wind tunnel assembly and an evaporation pan according to an embodiment of the present invention, and fig. 8 is a schematic structural exploded view of the wind tunnel assembly and the evaporation pan according to an embodiment of the present invention. Referring to fig. 7 and 8, an evaporating dish 90 is provided in the compressor compartment 13 and has a first receiving area 91 for receiving condensed water discharged from the first drain pipe 81, a second receiving area 92 for receiving condensed water discharged from the second drain pipe 82, and a connecting flow passage 93 communicating the first receiving area 91 and the second receiving area 92. The connecting flow channel 93 is provided in the duct assembly 60.

The air duct assembly 60 of the present invention divides the compressor compartment 13 into left and right portions in which two receiving areas of the evaporating dish 90 are respectively located so as to respectively receive condensed water discharged from two drain pipes extending to the two portions, and any drain pipe does not need to be provided in a particularly complex curved shape, thereby reducing the design difficulty and assembly difficulty of the drain pipe.

The remaining space of the two subspaces of the compressor compartment 13, which are separated by the duct assembly 60, must be different due to the presence of the compressor 51. The remaining subspace of the compressor 51 is smaller, and the remaining subspace of the subspace far from the compressor 51 is larger. For this reason, the first receiving area 91 is located at a side of the air duct assembly 90 away from the compressor 51, the second receiving area 92 and the compressor 51 are located at the same side of the cylinder assembly 60, and the cross-sectional area of the first receiving area 91 is larger than that of the second receiving area 92, so that the evaporating dish 90 having a larger capacity is arranged by fully utilizing the remaining space in the compressor compartment 13 as much as possible without structural interference, thereby improving the capacity of the evaporating dish 90 to receive condensed water.

Further, the height of the second receiving area 92 and the connecting flow path 93 in the vertical direction is higher than the height of the first receiving area 91 in the vertical direction, so that the second receiving area 92 and the connecting flow path 93 are suspended above the bottom plate 14 after the evaporating dish 90 is mounted on the bottom plate 14 of the refrigerator 1. Accordingly, the condensed water received by the second receiving area 92 has a tendency to flow toward the first receiving area 91, so that the volume requirement of the second receiving area 92 is low, i.e., the volume of the second receiving area 92 is not required to be large, and the condensed water can be effectively received, so that the evaporating dish 90 is very suitable for being arranged in a small space adjacent to the compressor 51 in the compressor compartment 13, and therefore, the evaporating dish 90 is very suitable for a refrigerator with a double-drainage system, and solves the problem about the drainage of the condensed water, which is generally possessed by the existing refrigerator.

Further, the bottom wall of the second accommodating area 92 extends obliquely downward from the second accommodating area 92 to the first accommodating area 91, which is beneficial to the condensed water in the second accommodating area 92 to flow to the first accommodating area 91 more quickly, so as to avoid more condensed water from accumulating in the second accommodating area 92 with smaller capacity.

In some embodiments, the air duct assembly 60 is provided with an avoidance gap 621, and the connection flow channel 93 is penetrated in the avoidance gap 621. The bottom outside of connecting runner 93 is equipped with downwardly convex supporting seat 94, and supporting seat 94 supports on bottom plate 14 to for unsettled connecting runner 93 and the regional 92 of second accommodation provide stable support, improved the structural stability of evaporating dish 90, prolonged its life.

Since the connecting flow channel 93 is suspended, a gap below the connecting flow channel 93 is inevitably formed at the bottom of the avoiding gap 621. When the cooling fan 52 is operated, a certain pressure difference is formed in the space at both sides of the air duct assembly 60, and under the action of the pressure difference, part of air flows back through the air duct assembly, so that hot air enters the space where the compressor 51 is located again, and the cooling efficiency of the compressor 51 is reduced. For this purpose, the support seat 94 is configured to block the flow-through surface of the avoidance gap 621 below the connection flow passage 93, that is, to block the gap formed at the bottom of the avoidance gap 621 and located below the connection flow passage 93. Therefore, the supporting seat 94 not only can support the connecting flow channel 93 and the second accommodating area 92, but also can prevent the hot air from flowing back through the gap, thereby ensuring a better heat dissipation effect in the compressor bin 13.

In some embodiments, a baffle 622 is provided at the relief notch 621, the baffle 622 having an open state for opening the flow passage of the evaporation pan 90 at the relief notch 621 and a closed state for blocking the flow passage. When the condensed water flows between the two accommodating areas of the evaporating dish 90, the baffle 622 can be in an opened state to conduct the overflow channel at the avoiding notch 621, so that the normal flow, collection and the like of the condensed water are not affected; when no condensed water flows between the two accommodating areas of the evaporating dish 90, the baffle 622 can be in a closed state to block the overflow channel at the avoiding gap 621, thereby preventing air from flowing through the avoiding gap 621, and effectively avoiding the problem of internal air backflow of the compressor bin 13.
