Detailed Description

The utility model provides a refrigerator, figure 1 is according to the utility model discloses a schematic structure chart of refrigerator of embodiment, figure 2 is according to the utility model discloses a schematic structure of refrigerator of embodiment breaks a drawing. Referring to fig. 1 and 2, the refrigerator 1 of the present invention includes a cabinet 10, a compressor 51, a heat dissipation fan 52, an air duct assembly 60, a first drain pipe 41, and a second drain pipe 42.

The bottom of the casing 10 defines a compressor compartment 13, and a first cooling chamber 112 and a second cooling chamber 122, which are independent of each other. The compressor 51 and the radiator fan 52 are disposed in the compressor compartment 13. The air duct assembly 60 is used for installing the heat dissipation fan 52, the air duct assembly 60 divides the space in the compressor compartment 13 into two subspaces which are side by side in the horizontal direction, and the compressor 51 is arranged in one of the subspaces. The first and second drain pipes 41 and 42 extend from the first and second cooling chambers 112 and 122, respectively, to the two subspaces of the compressor compartment 13. 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 further comprises an evaporation pan 30, the evaporation pan 30 being arranged inside the compressor compartment 13 and having two mutually communicating containing areas located respectively in the two subspaces of the compressor compartment 13 to receive the condensed water discharged from the first and second water discharge pipes 41 and 42, respectively. A partial section of the evaporating dish 30 is inserted into the air duct assembly 60, and a baffle plate 80 is disposed on the partial section, and the baffle plate 80 is configured to allow the condensed water to flow in the evaporating dish 30 and prevent the air flow generated between the two subspaces of the compressor compartment 13 through the evaporating dish 30. That is, the baffle plate 80 has no blocking effect on the condensed water but has a blocking effect on the air. Under the blocking action of the flow blocking plate 80, air in any one subspace of the compressor compartment 13 cannot flow to the other subspace through the evaporating dish 30.

The utility model discloses a refrigerator 1 has two mutually independent end and puts the cooling chamber, and every cooling chamber all corresponds and is equipped with a drain pipe, and two drain pipes extend to two subspaces that are located dryer subassembly 60 both sides in the compressor storehouse 13 respectively, and follow two drain pipe exhaust comdenstion waters and flow in the different holding region of evaporating dish 30 respectively. Moreover, a partial section of the evaporating dish 30 is inserted into the air duct assembly 60, and is particularly provided with a baffle plate 80. On one hand, the baffle plate 80 allows the condensed water to flow in the evaporation pan 30, i.e. the collection of the condensed water in the evaporation pan 30 is not affected; on the other hand, the baffle plate 80 can also prevent the two subspaces of the compressor compartment 13 from generating an airflow through the evaporating dish 30. Thus, the problem of collecting condensed water in a refrigerator with a double drainage system is solved by the evaporating dish 30, and air backflow in the compressor bin 13 is avoided, so that heat dissipation of heat-generating components in the compressor bin 13 is not affected.

It can be understood that the compressor 51 of the refrigerator, which is located at one side of the air duct assembly 60 in the compressor compartment 13, inevitably occupies a large space at the side, resulting in a small remaining space at the side and inconvenience in disposing an evaporation pan. Because of this, the evaporating dish of the prior art is usually arranged on the side remote from the compressor. However, the evaporating dish 30 of the present invention is particularly provided with two mutually communicating receiving areas, which can receive the condensed water discharged from the two drain pipes of the refrigerator, respectively. However, because of the existence of the compressor 51, the remaining space of the right subspace of the compressor 51 is smaller, resulting in the limited ability of the evaporation pan 30 to hold the condensed water in the holding area located in the right subspace, for this reason, the utility model discloses with the regional intercommunication of two holding of the evaporation pan 30, can converge in the great left side holding area of capacity when the amount of condensed water accumulation in the less right side holding area of capacity reaches the certain degree, reduced the volume requirement to the right side holding area, especially adapted to set up the less region in the space of neighbouring compressor in the compressor storehouse 13, consequently, the utility model discloses an evaporation pan 30 is very suitable for the refrigerator that has double drainage system, has solved the troublesome problem about the condensed water discharge that this kind of refrigerator of current has usually.

Also, the air duct assembly 60 of the refrigerator 1 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 the condensed water discharged from the two drain pipes extending to the left and right portions, which do not need to be provided in a particularly complicated curved shape. Moreover, partial sections of the evaporating dish 30 are arranged in the air duct assembly 60 in a penetrating mode, the air duct assembly 60 and the evaporating dish 30 are ensured to be still arranged in the transverse direction, the space in the height direction of the compressor bin 13 cannot be increased, the depth requirement on the front and back direction of the compressor bin 13 cannot be increased, and the structural layout rationality of all parts in the compressor bin 13 is improved.

Fig. 3 is a schematic structural view of an evaporating dish according to an embodiment of the present invention, fig. 4 is a schematic structural view in a compressor compartment according to an embodiment of the present invention, fig. 5 is a partial structural exploded view of fig. 4, and fig. 6 is a schematic cross-sectional view in a compressor compartment according to an embodiment of the present invention. In some embodiments, the evaporation pan 30 includes a first receiving region 31 for receiving the condensed water discharged from the first drain pipe 41, a second receiving region 32 for receiving the condensed water discharged from the second drain pipe 42, and a connection flow passage 33 communicating the first receiving region 31 and the second receiving region 32. The partial section penetrating through the air duct assembly 60 is a connecting flow passage 33.

Further, the second accommodation area 32 and the compressor 51 are in the same subspace of the compressor compartment 13, while the first accommodation area 31 is in the other subspace, and therefore, the capacity of the first accommodation area 31 can be set as large as possible. Specifically, the capacity of the first accommodation area 31 is at least larger than the capacity of the second accommodation area 32. The second receiving area 32 has a limited capacity and a limited ability to receive condensed water. Therefore, the height of the second accommodating area 32 in the vertical direction is higher than that of the first accommodating area 31 in the vertical direction in the present invention, so as to allow the water in the second accommodating area 32 to flow into the first accommodating area 31 through the connecting flow passage 33. Therefore, the condensed water received by the second receiving area 32 can automatically flow into the first receiving area 31 through the connecting flow passage 33, so that the requirement on the volume of the second receiving area 32 is low, that is, the volume of the second receiving area 32 does not need to be large, the condensed water can be effectively received,

specifically, the height of the second accommodating area 32 in the vertical direction is higher than that of the first accommodating area 31 in the vertical direction, and specifically, the height of the bottom wall of the second accommodating area 32 is higher than that of 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.

Alternatively, 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 region 31 is greater than that of the second receiving region 32, and thus, the capacity of the first receiving region 31 is greater for receiving more condensed water with the same cross-sectional area.

In some embodiments, the first receiving area 31 and the second receiving area 32 are disposed side by side in a horizontal direction. The bottom wall of the second receiving area 32 extends obliquely downward from the second receiving area 32 to the first receiving area 31. That is to say, the bottom wall of the second accommodating area 32 inclines downwards towards the first accommodating area 31, so that the condensed water in the second accommodating area 32 can flow to the first accommodating area 31 more quickly, and more condensed water is prevented from being accumulated in the second accommodating area 32 with smaller capacity.

In some embodiments, the inner bottom wall of the connection flow channel 33 or the inner bottom wall of the connection opening of the second accommodation area 32 and the connection flow channel 33 is provided with a water blocking rib 35 protruding upward to prevent water from flowing through the water blocking rib 35 when the water surface of the water blocking rib 35 facing the side of the second accommodation area 32 is lower than the water blocking rib 35. When the water surface of the water blocking rib 35 facing 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. Therefore, a water surface with a certain height can be formed in the second accommodating area 32, so that a water seal can be formed at the tail end of the second drain pipe.

Further, the inner bottom wall of the second receiving area 32 is provided with a plurality of support ribs 321 protruding upward, so that the end of the second drain pipe abuts against the support ribs 321, and a gap is formed between the end of the second drain pipe and the inner bottom wall of the second receiving area 32, so as to ensure that the condensed water in the second drain pipe can flow into the second receiving area 32 from the gap, and prevent the end of the second drain pipe from directly abutting against the inner bottom wall of the second receiving area 32 to cause the end of the second drain pipe to be blocked.

Further, the height of the water blocking rib 35 in the vertical direction is higher than the height of the support rib 321 in the vertical direction. Therefore, the height of the water surface in the second accommodating area 32 can be ensured to be higher than the height of the support rib 321, namely higher than the height of the tail end of the second water drainage pipe 42, so that the tail end of the second water drainage pipe 42 is ensured to be always below the water surface, normal drainage of condensed water is not influenced, external air with higher temperature can be prevented from entering the refrigerator 1 through the second water drainage pipe 42, and energy consumption of the refrigerator is saved.

In some embodiments, the baffle plate 80 includes a horizontal plate 81 covering the connecting channel 33 and a vertical plate 82 extending from one end of the horizontal plate 81 to the bottom wall of the evaporation pan 30, and a gap is formed between the extending end of the vertical plate 82 and the inner bottom wall of the evaporation pan 30 for the condensed water to flow through.

Further, the vertical plate body 82 of the flow blocking plate 80 is located on one side of the water blocking rib 35 facing the second accommodating area 32, and the height of the extending end of the vertical plate body 82 in the vertical direction is lower than the height of the top of the water blocking rib 35 in the vertical direction. Because the side of the water blocking rib 35 facing the second accommodating area 32 has the condensed water with the height approximately equal to that of the water blocking rib 35, the tail end of the vertical plate 82 is always below the water surface, so that a water seal is formed between the vertical plate 82 and the water blocking rib 35, the condensed water is only allowed to flow through the gap between the vertical plate 82 and the inner bottom wall of the evaporating dish 30, air is not allowed to flow through the gap, and the air backflow problem in the compressor bin 13 is effectively avoided.

Fig. 7 is a schematic structural diagram of an air duct assembly according to an embodiment of the present invention. In some embodiments, the air duct assembly 60 has an avoiding notch 621 formed thereon for the connection flow passage 33 to pass through. Specifically, the air duct assembly 60 includes a fan installation part 61 at a rear side and a sealing diaphragm 62 connected to a front side of the fan installation part 61. The radiator fan 52 is mounted in the fan mounting portion 61, and an escape notch 621 is provided in the seal partition plate 62.

Further, the other end of the horizontal plate 81 of the flow baffle 80 extends to the avoiding notch 621, and the other end of the horizontal plate 81 and the matching surface of the avoiding notch 621 form an airtight seal. Alternatively, the horizontal plate 81 is inserted into the avoiding notch 621, and the matching surface between the horizontal plate 81 and the avoiding notch 621 forms an airtight seal. Thus, air can be prevented from flowing back through the mating surface between the baffle plate 80 and the avoiding notch 621.

In some embodiments, the connection channel 33 is suspended above the bottom plate 14 of the box 10 to avoid the connection channel 33 from blocking the air inlet and outlet of the refrigerator bottom plate 14. The bottom outside of connecting runner 33 is equipped with downward convex supporting seat 34, and supporting seat 34 supports on bottom plate 14 for unsettled connecting runner 33 provides stable support, has improved evaporating dish 30's structural stability, has prolonged its life.

For installing evaporating dish 30, the utility model discloses set up on the sealed partition plate 62 of dryer subassembly 60 and dodged breach 621, however, owing to connect the unsettled setting of runner 33, consequently, inevitably can form the space that is located connection runner 33 below in the bottom of dodging breach 621. When the heat dissipation fan 52 operates, a certain pressure difference is formed in the spaces on both sides of the air duct assembly 60, and under the action of the pressure difference, a part of air flow flows back through the gap, so that hot air enters the space where the compressor 51 is located again, and the heat dissipation efficiency of the compressor 51 is reduced.

Therefore, the utility model discloses set up supporting seat 34 to the shutoff and dodge breach 621 and be located the current surface of connecting the runner 33 below, the shutoff dodges the space that is located connecting the runner 33 below that the bottom of breach 621 formed promptly. Therefore, the support seat 34 can not only support the connecting flow passage 33 and the second accommodating area 32, but also prevent the hot air from flowing back through the gap, thereby ensuring a good heat dissipation effect in the compressor compartment 13.

Fig. 8 is a schematic structural view of an evaporating dish according to another embodiment of the present invention, fig. 9 is a schematic structural view in a compressor compartment according to another embodiment of the present invention, fig. 10 is a partial structural exploded view of fig. 9, and fig. 11 is a schematic cross-sectional view in a compressor compartment according to another embodiment of the present invention. In other embodiments, the evaporation pan 30 includes a main receiving area 31' in one of the sub-spaces and a connecting channel 33' extending from the main receiving area 31' to the other sub-space, and the end of the drain pipe in the other sub-space extends into the connecting channel 33. The connecting channel 33 is inserted into the duct assembly 60 to form the above-mentioned partial section. That is, the main receiving area 31 and the connecting channel 33' form two receiving areas of the evaporating dish 30. Because the restriction in space, connecting runner 33' is long and thin shape usually, and the ability of holding comdenstion water is very limited, for this reason, the utility model discloses further will connect runner 33' and highly set to be higher than main holding area 31' in vertical height at vertical, from this, the comdenstion water that connects runner 33' received can directly converge main holding area 31', and can not deposit up in connecting runner 33', and is lower to the size requirement who connects runner 33', especially adapted setting is in the less region in space of the neighbouring compressor in the compressor storehouse.

Specifically, the height of the connecting flow passage 33 'in the vertical direction is higher than that of the main accommodating area 31', and specifically, the height of the bottom wall of the connecting flow passage 33 'is higher than that of the bottom wall of the main accommodating area 31', so as to ensure that the condensed water in the connecting flow passage 33 'has a tendency to flow toward the main accommodating area 31'.

In some embodiments, one end of the connection flow channel 33' is open and communicates with the main receiving area 31' to form an open end of the connection flow channel 33', and the other end of the connection flow channel 33' is provided with an end plate 331 to form a closed end of the connection flow channel 33 '.

Further, the bottom wall of the connecting flow passage 33' extends obliquely downward from the closed end thereof to the open end thereof. That is, the bottom wall of the connecting flow channel 33' is inclined downward toward the main receiving area 31', which is beneficial for the condensed water in the connecting flow channel 33' to flow to the main receiving area 31' more quickly, so as to avoid the condensed water accumulating in the connecting flow channel 33' with smaller capacity.

In some embodiments, the baffle plate 80 includes a horizontal plate 81 covering the connecting channel 33 and a vertical plate 82 bent downward from one end of the horizontal plate 81. The vertical plate 82 is closely attached to the inner surface or the outer surface of the end plate 331, the horizontal plate 81 is provided with a limiting hole 811, and the end of the drain pipe located in the other subspace passes through the limiting hole 811 and extends into the connecting flow passage 33'. That is, the baffle plate 80 completely isolates the connecting flow passage 33 from the compressor housing 13, thereby effectively preventing the occurrence of the backflow phenomenon.

Specifically, the main receiving region 31 'receives the condensed water discharged from the first drain pipe 41, and the connection flow passage 33' receives the condensed water discharged from the second drain pipe 42.

In some embodiments, the second water discharge pipe 42 includes a second main pipe 421 directly connected to the second cooling chamber 122 and a second connection pipe 422 connected to the second main pipe 421, the second main pipe 421 is located at a side of the connection flow passage 33 'facing away from the main accommodating area 31' in a transverse direction; the second connecting pipe 422 is led out from the second main pipe 421, bent toward the main accommodating area 31', bent downward, and extended into the connecting channel 33'. That is, the connection pipe of the second drain pipe 42 has a shape bent toward the main receiving region 31', and thus, the connection flow passage 33' does not need to extend to a position corresponding to the main pipe body of the second drain pipe 42 to effectively receive the condensed water discharged from the second drain pipe 42, and the length of the connection flow passage 33' is shortened.

The utility model discloses a bending shape to the terminal zone section of second drain pipe 42 designs very much, has reduced the requirement to connecting runner 33 'length, is particularly useful for the space undersize in the compressor storehouse 13 subspace at compressor 51 place, causes to connect runner 33' can not extend to the condition with the corresponding position of the main pipe body of second drain pipe 42, and the design is very nimble.

It is understood that although the second connection pipe 422 of the second water discharge pipe 42 has a certain degree of bent shape design in this embodiment, the entire second water discharge pipe 42 is located at the same side of the air duct assembly 60 in any case, and the degree of bending of the second connection pipe 422 is within an easily achievable range.

Further, the second connection pipe 422 may be a hose, and it should be noted that the term hose does not only mean that the hose is made of a soft material, and for convenience of understanding, the hose is defined as a pipe member that can be bent to some extent or stretched along the length direction or compressed along the length direction without failure. By "to some extent" is meant that at least the above-mentioned deformation of the drain pipe 100 can occur.

Specifically, the second connection pipe 422 may be a rubber pipe or a resin pipe. In particular, it may be a corrugated pipe, and the material of the corrugated pipe may be polyethylene (i.e. PE corrugated pipe), or even a metal material with high plasticity.

In some embodiments, the air duct assembly 60 has an escape notch 621 for the connection channel 33' to pass through. The other end of the horizontal plate 81 extends to the avoiding notch 621, and the other end of the horizontal plate 81 and the matching surface of the avoiding notch 621 form an airtight seal; alternatively, the horizontal plate 81 is inserted into the avoiding notch 621, and the matching surface between the horizontal plate 81 and the avoiding notch 621 forms an airtight seal.
