Detailed Description

The present invention first provides an evaporation pan for a refrigerator having a first drain pipe and a second drain pipe which are provided independently of each other. That is, the evaporating dish of the present invention is suitable for a refrigerator having a double drain system.

Fig. 1 is a schematic structural view of an evaporation pan for a refrigerator according to an embodiment of the present invention, and fig. 2 is a schematic structural view of a bottom of the evaporation pan for a refrigerator according to an embodiment of the present invention. Referring to fig. 1 and 2, the evaporation pan 30 of the present invention includes a first receiving area 31, a second receiving area 32, and a connecting flow channel 33. The first receiving area 31 is for receiving condensed water discharged from a first drain pipe of the refrigerator, and the second receiving area 32 is for receiving condensed water discharged from a second drain pipe of the refrigerator. And, the height of the second accommodation region 32 in the vertical direction is higher than the height of the first accommodation region 31 in the vertical direction. The connecting flow passage 33 communicates the first receiving area 31 and the second receiving area 32 to allow water within the second receiving area 32 to flow into the first receiving area 31. The capacity of the first receiving area 31 is greater than the capacity of the second receiving area 32.

The compressor of refrigerator is located the one side of dryer subassembly in the compressor storehouse, can occupy the great space of this side certainly, leads to this side surplus space less, is inconvenient for setting up the evaporation dish. Because of this, the evaporating dish in the prior art is usually arranged at the side remote from the compressor. However, the evaporating dish 30 of the present invention is particularly provided with two receiving areas to receive condensed water discharged from two drain pipes of the refrigerator, respectively. In addition, the two accommodating areas are communicated through the connecting flow channel, the height of the second accommodating area 32 is higher than that of the first accommodating area 31, and therefore, condensed water received by the second accommodating area 32 can automatically flow into the first accommodating area 31 through the connecting flow channel 33, and therefore, the volume requirement on the second accommodating area 32 is low, namely, the volume of the second accommodating area 32 is not required to be large, condensed water can be effectively received, and the evaporating dish 30 is very suitable for being arranged in an area with a small space adjacent to a compressor in a compressor bin, and is very suitable for a refrigerator with a double-drainage system, and the problem about condensed water drainage, which is generally possessed by the conventional refrigerator, is solved.

Specifically, the height of the second accommodating area 32 in the vertical direction is higher than the height of the first accommodating area 31 in the vertical direction, which may specifically be that the bottom wall of the second accommodating area 32 is higher than the bottom wall of the first accommodating area 31, so as to ensure that the condensed water in the second accommodating area 32 has a tendency to flow toward the first accommodating area 31.

Optionally, the top opening of the first receiving area 31 is flush with the top opening of the second receiving area 32 in the vertical direction. At this time, the depth of the first receiving area 31 is greater than that of the second receiving area 32, and thus, the capacity of the first receiving area 31 is greater in the same cross-sectional area, so that more condensed water is conveniently received.

The remaining space of the two parts of the compressor compartment separated by the air duct assembly must be different due to the presence of the compressor. The portion where the compressor is provided has a smaller remaining space and the portion far from the compressor has a larger remaining space. To this end, in some embodiments, the first receiving area 31 is located at a side of the air duct assembly away from the compressor, the second receiving area 32 and the compressor are located at the same side of the air duct assembly, and the cross-sectional area of the first receiving area 31 is larger than that of the second receiving area 32, so that the evaporation dishes 30 having larger capacity are arranged to fully utilize the remaining space in the compressor compartment as much as possible without structural interference, thereby improving the capacity of the evaporation dishes 30 to receive condensed water.

In some embodiments, the first receiving area 31 and the second receiving area 32 are disposed side by side in the horizontal direction. The bottom wall of the second receiving area 32 extends obliquely downward in a direction from the second receiving area 32 toward the first receiving area 31. That is, the bottom wall of the second accommodating area 32 is inclined downward toward the first accommodating area 31, so that the condensed water in the second accommodating area 32 flows to the first accommodating area 31 more quickly, and more condensed water is prevented from accumulating in the second accommodating area 32 with smaller capacity.

Specifically, the bottom wall of the second receiving area 32 may extend obliquely downward straight along a fixed slope, or may extend curvedly downward along a curve.

In some embodiments, the height of the connecting flow channel 33 in the vertical direction is higher than the height of the first receiving area 31 in the vertical direction, so that the connecting flow channel 33 and the second receiving area 32 are both suspended above the bottom plate of the refrigerator after the evaporating dish 30 is mounted to the bottom plate of the refrigerator. The bottom plate of the refrigerator refers to a plate body located at the bottom of the compressor compartment and used for supporting the evaporating dish 30, the compressor, the air duct assembly and other components.

Specifically, the bottom wall of the connection flow passage 33 is higher than the bottom wall of the first receiving area 31, so that the condensed water in the connection flow passage 33 has a tendency to flow toward the first receiving area 31, thereby causing the condensed water to collect in the first receiving area 31.

And, connecting runner 33 and second accommodation region 32 all hang to lie in the air above the refrigerator bottom plate, all are formed with the space of stepping down between the diapire of connecting runner 33 and the refrigerator bottom plate promptly and between diapire and the refrigerator bottom plate of second accommodation region 32 to the air current passes through of being convenient for, avoids connecting runner 33 and second accommodation region 32 to shelter from original structure such as inlet and outlet on the refrigerator bottom plate.

The applicant has appreciated that the suspended connecting runner 33 and the second receiving area 32 are subject to increased load bearing and deformation after receiving the condensed water, and even breakage is subject to occur at the connection between the connecting runner 33 and the first receiving area 31 and the connection between the first receiving area 31 and the second receiving area 32. To this end, in some embodiments, the connecting flow channel 33 and/or the bottom outer side of the second receiving area 32 are provided with a supporting seat 34 protruding downward, and the supporting seat 34 is for supporting on a bottom plate of the refrigerator after the evaporating dish 30 is mounted on the bottom plate. The support seat 34 can provide stable support for the suspended connecting runner 33 and the second accommodating area 32, so that the structural stability of the evaporating dish 30 is improved, and the service life of the evaporating dish is prolonged.

Further, a reinforcing rib is further disposed on the outer side of the bottom of the connecting runner 33, and the reinforcing rib can extend along the length direction of the connecting runner 33, so as to further enhance the structural strength of the connecting runner 33.

In some embodiments, the inner bottom wall of the second accommodating area 32 is provided with a plurality of supporting ribs 321 protruding upwards, so that the tail end of the second drain pipe is abutted against the supporting ribs 321, and a gap is formed between the tail end of the second drain pipe and the inner bottom wall of the second accommodating area 32, so that condensed water in the second drain pipe can flow into the second accommodating area 32 from the gap, and the tail end of the second drain pipe is prevented from being directly abutted against the inner bottom wall of the second accommodating area 32 to cause blockage of the tail end of the second drain pipe.

In some embodiments, the evaporating dish 30 further includes a water blocking rib 35, wherein the water blocking rib 35 is disposed on the inner bottom wall of the connecting channel 33 or on the inner bottom wall of the connecting port between the second accommodating area 32 and the connecting channel 33. When the water surface height of the water blocking rib 35 toward the side of the second receiving area 32 is lower than the water blocking rib 35, the condensed water does not pass through the water blocking rib 35 but remains in the second receiving area 32. Thus, a water surface of a certain height can be formed in the second receiving area 32, so that a water seal is formed at the end of the second drain pipe.

Further, the water blocking rib 35 is higher in the vertical direction than the supporting rib 321. Therefore, the water surface height in the second accommodating area 32 can be ensured to be always higher than the height of the supporting rib 321, namely, the height of the tail end of the second drain pipe, so that the tail end of the second drain pipe is ensured to be always below the water surface, normal drainage of condensed water is not affected, and external air with higher temperature can be prevented from entering the refrigerator through the second drain pipe, thereby being beneficial to saving energy consumption of the refrigerator.

In some embodiments, the first receiving area 31, the second receiving area 32, and the connecting runner 33 are integrally formed.

In other embodiments, the first receiving area 31, the second receiving area 32, and the connecting channel 33 may be connected together by welding, sleeving, clamping, or the like.

The present invention also provides a refrigerator, fig. 3 is a schematic structural view of the refrigerator according to an embodiment of the present invention, fig. 4 is a schematic sectional view taken along a sectional line A-A in fig. 3, fig. 5 is a schematic sectional view taken along a sectional line B-B in fig. 3, and fig. 6 is a schematic exploded view of a portion of the refrigerator according to an embodiment of the present invention. Referring to fig. 3 to 6, the refrigerator 1 of the present invention includes a cabinet 10, a first evaporator 21, a second evaporator 22, a first drain pipe 41, and a second drain pipe 42.

The bottom of the case 10 defines a compressor compartment 13, and first and second cooling chambers 112 and 122, which are independent of each other. The first evaporator 21 and the second evaporator 22 are provided in the first cooling chamber 112 and the second cooling chamber 122, respectively. The first drain pipe 41 and the second drain pipe 42 extend from the first cooling chamber 112 and the second cooling chamber 122 to the compressor compartment 13, respectively. That is, the refrigerator of the present invention has a double drain system to drain condensed water in the first cooling chamber 112 and the second cooling chamber 122, respectively.

In particular, the refrigerator 1 of the present invention further includes the evaporation pan 30 described in any of the above embodiments, the evaporation pan 30 being disposed in the compressor compartment 13 to receive the condensed water discharged from the first drain pipe 41 through the first receiving area 31 thereof and the condensed water discharged from the second drain pipe 42 through the second receiving area 32 thereof.

The refrigerator 1 of the invention comprises two cooling chambers, two evaporators, two drain pipes and an evaporating dish, and can utilize the special structure of the evaporating dish 30 on the basis of not changing the original structural layout (such as the layout among a compressor, a condenser, a wind barrel component, a cooling fan and the like) in the compressor bin 13, so that the condensed water discharged by the two drain pipes can flow into the evaporating dish 30, and the design is very ingenious.

In some embodiments, the refrigerator 1 further includes a compressor 51, a heat dissipation fan 52, and a fan cartridge assembly 60. The compressor 51 and the heat radiation fan 52 are disposed in the compressor housing 13. The air duct assembly 60 is used for installing the cooling fan 52, and the air duct assembly 60 extends along the depth direction (i.e., the front-rear direction) of the box 10 to divide the space in the compressor compartment 13 into two parts which are laterally arranged side by side. That is, the space in the compressor compartment 13 is divided into left and right subspaces by the duct assembly 60.

Fig. 7 is a schematic assembly view of an evaporating dish, a dryer assembly and a refrigerator bottom plate according to an embodiment of the present invention. Further, the first receiving area 31 and the second receiving area 32 of the evaporating dish 30 are located at both lateral sides of the air duct assembly 60, respectively, and the compressor 51 and the second receiving area 32 are located at the same lateral side of the air duct assembly 60. That is, the compressor 51 and the second receiving area 32 are located in the same subspace of the compressor compartment 13, and the first receiving area 31 is located in the other subspace of the compressor compartment 13.

The second receiving area 32 has a limited arrangement space due to the compressor 51, and thus the capacity of the second receiving area 32 is limited. For this reason, the height of the second accommodating area 32 in the vertical direction is set to be higher than the height of the first accommodating area 31 in the vertical direction, so that the condensed water in the second accommodating area 32 can be timely converged into the first accommodating area 31 through the connecting flow channel 33, and some column problems caused by small capacity of the second accommodating area 32 are solved. The space of the subspace of the compressor compartment 13 where the first receiving area 31 is located is large, so that the capacity of the first receiving area 31 can be set as large as possible, which is advantageous in storing the condensed water received by itself from the first drain pipe 41 and the condensed water flowing in from the second receiving area 32 from the second drain pipe 42.

The air duct assembly 60 of the present invention divides the compressor compartment 13 into left and right portions in which the two receiving areas of the evaporating dish 30 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.

FIG. 8 is a schematic block diagram of a duct assembly according to one embodiment of the present invention. In some embodiments, the duct assembly 60 includes a blower mounting portion 61 on a rear side and a sealing bulkhead 62 connected to a front side of the blower mounting portion 61. The heat radiation fan 52 is mounted in the fan mounting portion 61. The sealing partition plate 62 is provided with an avoiding notch 621, and the connecting flow passage 33 of the evaporating dish 30 is arranged in the avoiding notch 621 in a penetrating manner.

The connecting flow channel 33 of the evaporating dish 30 is arranged in the sealing partition plate 62 of the air duct assembly 60 in a penetrating way, normal installation of the heat dissipation fan 52 is not affected, the air duct assembly 60 and the evaporating dish 30 are ensured to be still arranged transversely, space in the height direction of the compressor bin 13 is not increased, depth requirements in the front-back direction of the compressor bin 13 are not increased, and structural layout rationality of all components in the compressor bin 13 is improved.

It should be understood that, to avoid taking up too much space, the connecting flow channel 33 for connecting the first accommodating area 31 and the second accommodating area 32 is preferably an elongated flow channel, and the sealing partition 62 only needs to be provided with a avoiding notch 621 which is approximately equal to the cross-sectional dimension of the connecting flow channel 33. And, the bottom of the escape notch 621 is opened for the connection flow passage 33 to be fitted into the escape notch 621 from the bottom up.

In some embodiments, the connecting runner 33 and the second accommodating area 32 are all suspended above the bottom plate 14 of the box 10, so as to avoid the connecting runner 33 and the second accommodating area 32 from shielding the original air inlet and outlet structures on the bottom plate 14 of the refrigerator.

Further, the bottom outer side of the connecting runner 33 is provided with a supporting seat 34 protruding downwards, and the supporting seat 34 is supported on the bottom plate 14 to provide stable support for the suspended connecting runner 33 and the second accommodating area 32, so that the structural stability of the evaporating dish 30 is improved, and the service life of the evaporating dish is prolonged.

When the heat radiation fan 52 is started, an airflow is generated in the compressor compartment 13 to radiate heat from the compressor 51, the condenser, and the like. The applicant has realized that, in order to increase the heat dissipation effect, the air flow in the compressor compartment 13 preferably flows along a predetermined path, for example, the external air enters the side of the compressor 51 through the air inlet, flows from the side of the compressor 51 to the side of the first accommodating area 31 through the heat dissipation fan 52, and finally returns to the external space through the air outlet; or the external air enters the side where the first accommodating area 31 is located through the air inlet, flows to the side where the compressor 51 is located through the cooling fan 52 from the side where the first accommodating area 31 is located, and finally returns to the external space through the air outlet. The direction of flow of the air flow depends on the specific arrangement of the heat dissipation fan 52.

In order to install the evaporation pan 30, the sealing partition plate 62 of the air duct assembly 60 is provided with the avoiding notch 621, however, because the connecting flow channel 33 is arranged in a suspended manner, a gap below the connecting flow channel 33 is inevitably formed at the bottom of the avoiding notch 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 34 is provided to block the flow-through surface of the avoidance gap 621 below the connection flow passage 33, that is, to block the gap formed at the bottom of the avoidance gap 621 and located below the connection flow passage 33. Therefore, the supporting seat 34 not only can support the connecting runner 33 and the second accommodating area 32, but also can prevent hot air from flowing back through the gap, so that a good heat dissipation effect in the compressor bin 13 is ensured.

Specifically, the supporting seat 34 may be disposed below the connection channel 33 at the position of the avoidance gap 621, and by reasonably selecting the position of the supporting seat 34, the supporting seat has various beneficial effects, and the design is very ingenious.

Fig. 9 is a schematic structural view of an evaporation pan according to another embodiment of the present invention. In some embodiments, the water blocking ribs 35 located at the avoiding notch 621 are provided inside the connecting flow channel 33. That is, unlike the foregoing embodiment, in the embodiment shown in fig. 9, the water deflector 35 is preferably provided in the connecting flow passage 33 at the escape notch 621.

Further, the water blocking ribs 35 extend from three inner walls of the connecting flow channel 33 to the radial inner side of the connecting flow channel 33, respectively, to form water flow holes 36 inside the water blocking ribs 35, and the flow area of the water flow holes 36 is smaller than that of other sections of the connecting flow channel 33 except the water flow holes 36. Here, "inner" means a radially inner side of the connecting flow path 33.

That is, the water deflector 35 of the further embodiment of the present invention includes not only a bottom section extending upward from the inner bottom wall of the connecting flow passage 33, but also side sections extending toward each other from both side walls of the connecting flow passage 33. Therefore, the water blocking ribs 35 not only can play a role in blocking water, but also can reduce the overflow area of the connecting flow channel 33 at the water blocking ribs 35, not only can allow condensed water to flow, but also can play a role in preventing part of space from flowing back.

In some embodiments, referring to fig. 1, the evaporation pan 30 further includes a connection pad 37, one edge of the connection pad 37 is connected to one edge of the first receiving area 31, the other edge of the connection pad 37 is connected to one side of the connection flow channel 33, and the other edge of the connection pad 37 is connected to one edge of the second receiving area 32 to support the connection flow channel 33 and the second receiving area 32 through the connection pad 37. Specifically, the connecting base plate 37 connects the part of the edges of the connecting runner 33 and the second accommodating area 32 which are suspended with the part of the edges of the first accommodating area 31 which are arranged on the refrigerator bottom plate 14, plays a certain supporting role on the connecting runner 33 and the second accommodating area 32, avoids deformation or fracture of the connecting runner 33 and the second accommodating area 32, and further improves the structural strength of the evaporating dish 30.
