Detailed Description

The utility model provides a refrigerator, figure 1 is according to the utility model discloses a schematic structure chart of refrigerator of an embodiment, figure 2 is according to the utility model discloses a schematic structure of refrigerator of an embodiment breaks up. Referring to fig. 1 and 2, the refrigerator 1 of the present invention includes a box 10, a compressor compartment 13 is defined at the bottom of the box 10, and a compressor 51 and a heat dissipation fan 52 are disposed in the compressor compartment 13.

Further, the refrigerator 1 further includes an evaporating dish 30 and an air duct assembly 60 for mounting the heat dissipation fan 52. The air duct assembly 60 divides the space inside the compressor compartment 13 into two subspaces side by side in the horizontal direction, and the compressor 51 is disposed in one of the subspaces. Specifically, the air duct assembly 60 may extend in the depth direction of the casing 10 to divide the space inside the compressor compartment 13 into two side-by-side subspaces on the left and right. Of course, the air duct assembly 60 may also extend vertically in other directions to divide the space inside the compressor compartment 13 into two subspaces side by side in other horizontal directions.

Fig. 3 is a schematic assembly view of an evaporation pan and a wind barrel assembly according to an embodiment of the present invention, and fig. 4 is a schematic structural exploded view of fig. 3. The evaporating dish 30 has two receiving areas respectively located in the two subspaces and communicated with each other to respectively receive the condensed water discharged into the two subspaces. An avoiding gap 621 is formed in the air duct assembly 60, and a part of the section of the evaporating dish 30 penetrates through the avoiding gap 621; the avoiding notch 621 is provided with a baffle 80, and the baffle 80 has an open state for opening the overflowing channel of the evaporating dish 30 at the avoiding notch 621 and a closed state for blocking the overflowing channel.

The utility model discloses a refrigerator 1 is equipped with dryer subassembly 60 in its compressor storehouse 13, and dryer subassembly 60 falls into compressor storehouse 13 along two subspaces that the horizontal direction is side by side, and evaporation ware 30 has two accommodation areas that just each other UNICOM that are located two subspaces respectively, and the partial district section of evaporation ware 30 wears to establish in the breach 621 of dodging of dryer subassembly 60. Therefore, the areas on both sides of the air duct assembly 60 can realize fluid intercommunication through the avoidance gap 621, that is, the condensed water in any accommodating area of the evaporation pan 30 can flow to another accommodating area of the evaporation pan 30 through the avoidance gap 621, and the air in any subspace of the compressor compartment 13 can also flow to another subspace of the compressor compartment 13 through the avoidance gap 621. However, when the heat dissipation fan 52 operates, the air flowing in the two subspaces of the compressor compartment 13 at the avoiding notch 621 forms an air backflow in the compressor compartment 13, which is not favorable for heat dissipation in the compressor compartment 13.

Therefore, the baffle 80 is particularly arranged at the position of the avoiding notch 621, when the condensed water flows between the two accommodating areas of the evaporating dish 30, the baffle 80 can be in an open state to conduct the overflowing channel at the position of the avoiding notch 621, so that the normal flowing, collecting and the like of the condensed water cannot be influenced; when no condensed water flows between the two accommodating areas of the evaporating dish 30, the baffle 80 can be in a closed state to block the overflowing channel at the avoiding notch 621, so that air is prevented from flowing through the avoiding notch 621 to form airflow, and the problem of backflow of air inside the compressor bin 13 is effectively avoided.

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 evaporation pan 30 of the present invention is particularly provided with two mutually communicating accommodating areas, which can respectively receive the condensed water discharged to the two subspaces. However, because of the existence of compressor 51, the remaining space that is equipped with the right side subspace of compressor 51 is less, and the holding condensate water ability that leads to the holding region that is located the right side subspace of evaporating dish 30 is limited, for this reason, the utility model discloses with two holding region intercommunications of evaporating dish 30, can converge in the great left side holding region of capacity when the condensate water accumulation in the less right side holding region of capacity reaches the certain degree in, reduced the volume requirement to the right side holding region, the less region in the space of neighbouring compressor of especially adapted setting in compressor storehouse 13, consequently, the utility model discloses an evaporating dish 30 is applicable to the refrigerator that has double drainage system very much, has solved the troublesome problem about the condensate water discharge that current this type of refrigerator usually had.

Moreover, partial sections of the evaporating dish 30 are arranged in the air duct assembly 60 in a penetrating manner, so that the air duct assembly 60 and the evaporating dish 30 are ensured to be still arranged transversely, the space in the height direction of the compressor bin 13 cannot be increased, the depth requirement in the front-rear direction of the compressor bin 13 cannot be increased, and the structural layout rationality of all parts in the compressor bin 13 is improved.

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.

In some embodiments, the flap 80 is configured to rotate about its top axis 81 to its open position under the influence of water flow in the flow passage and to rotate about its top axis 81 to its closed position under its own weight. That is, the flapper 80 is mechanically pivoted by the water flow action and the self-gravity action, the structure is very simple, and there is no need to design complicated control logic.

Further, the avoiding notch 621 has an upstream side in the water flow direction in the flow passage and a downstream side in the water flow direction in the flow passage. The baffle 80 is located downstream of the relief notch 621. On one hand, when the water flow in the overflow channel generates a force towards the downstream side of the avoiding notch 621 on the bottom of the baffle 80, the baffle 80 is not hindered to pivot to the open state; on the other hand, when no condensed water flows through the overflow channel, the baffle 80 can pivot downwards until the baffle abuts against the wall surface around the avoiding notch 621, so that the area of the matching surface between the baffle 80 and the avoiding notch 621 is increased, and good airtight sealing is formed between the baffle 80 and the avoiding notch 621.

In some embodiments, referring to fig. 4, the baffle 80 is removably connected to the air duct assembly 60. Specifically, the baffle 80 can be assembled to the air duct assembly 60 by a movable assembly, such as a snap fit, a plug fit, etc.

In other embodiments, referring to the schematic exploded view of an evaporation pan and air duct assembly according to another embodiment of the present invention shown in fig. 5, the baffle 80 may also be integrally formed with the air duct assembly 60. At this time, the connection between the shutter 80 and the air duct assembly 60 is thin, which can allow the shutter 80 to pivot within a certain range with respect to the air duct assembly 60. At this time, the junction between the baffle 80 and the air duct assembly 60 forms a rotation axis of the baffle 80.

Fig. 6 is a schematic enlarged view of a part of the structure in fig. 4. In some embodiments, the top of the flap 80 is pivotally connected to the duct wall of the duct assembly 60 above the bypass aperture 621. The bottom of the baffle 80 is in contact with the inner bottom wall of the evaporation pan 30 in the closed state of the baffle 80, so that an airtight seal is formed between the bottom of the baffle 80 and the inner bottom wall of the evaporation pan 30, and air is prevented from flowing back through the mating surface between the bottom of the baffle 80 and the inner bottom wall of the evaporation pan 30.

Furthermore, a hook 63 is arranged on the wall of the air duct above the avoiding notch 621, a hanging lug 81 is arranged at the top of the baffle 80, and the hanging lug 81 is rotatably hung on the hook 63. During assembly, the hanging lug 81 is directly hung on the hanging hook 63, and the assembly is very simple.

In other embodiments, the positions of the hook 63 and the hanging lug 81 can be interchanged.

In some embodiments, the hook 63 has a mounting groove 631 for the hook 81 to be snapped therein, and two opposite guide surfaces 632 for defining the mounting groove 631 gradually extend obliquely toward each other in the snapping direction of the hook 81, such that the width of the mounting groove 631 is tapered in the snapping direction of the hook 81. On one hand, when the device is installed, the guide surface 632 can guide the hanging lug 81 to be slowly clamped into the installation groove 631, so that resistance encountered in the clamping process of the hanging lug 81 is reduced, and the assembly efficiency is improved; on the other hand, after the hanging lug 81 is inserted into the mounting groove 631 and hung on the hook 63, it will not fall off the hook 63, and the stability of the assembly between the hook 63 and the hanging lug 81 is improved.

Furthermore, the hook 63 is arc-shaped, and each guide surface 632 of the hook 63 is smoothly connected with the outer peripheral wall and the inner peripheral wall of the hook 63, so that not only can the guide function be further achieved, but also the resistance encountered in the process of clamping the hanging lug 81 can be reduced.

Specifically, the mounting groove 631 has a notch inclined upward so that the hanging lug 81 is caught into the hook 63 from above downward, and further the hanging lug 81 is prevented from falling off from the hook 63.

In some embodiments, the partial section passing through the avoiding notch 621 is located above the bottom plate 14 of the box 10 in a suspended manner, so as to prevent the partial section from shielding the original air inlet and outlet structure on the bottom plate 14 of the refrigerator. A support seat 34 protruding downwards is arranged on the outer side of the bottom of the partial section; the support base 34 is supported on the bottom plate 14 to provide a stable support for the suspended sub-section, thereby improving the structural stability of the evaporating dish 30 and prolonging the service life thereof.

In order to install the evaporating dish 30, the utility model discloses set up on the sealed baffle 62 of dryer subassembly 60 and dodge breach 621, however, because the unsettled setting of some segmentation of evaporating dish 30, consequently, inevitably can form the space that is located this some segmentation 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 the excessive current surface that breach 621 is located this part district section below, the shutoff is dodged the space that is located this part district section below that the bottom of breach 621 formed promptly. The support seat 34 can thus not only support the partial section, but also prevent the hot air from flowing back through the gap, ensuring a better heat dissipation in the compressor compartment 13.

In some embodiments, the bottom of the housing 10 further defines a first cooling chamber 112 and a second cooling chamber 122 that are independent of each other. The refrigerator 1 further includes a first drain pipe 41 and a second drain pipe 42 extending from the first cooling chamber 112 and the second cooling chamber 122 to the two subspaces of 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.

Further, the evaporation pan 30 includes a first receiving area 31 for receiving the condensed water discharged from the first drain pipe 41, a second receiving area 32 for receiving the condensed water discharged from the second drain pipe 42, and a connection flow passage 33 communicating the first receiving area 31 and the second receiving area 32. The connecting channel 33 is inserted into the duct assembly 60 to form the above-mentioned partial section.

In some embodiments, the second accommodation region 32 and the compressor 51 are in the same subspace of the compressor bin 13, while the first accommodation region 31 is in another subspace, and therefore, the capacity of the first accommodation region 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 of the present invention is higher than the height of the first accommodating area 31 in the vertical direction, 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, and therefore, 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, and 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, 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.

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 toward the first receiving area 31. That is to say, the bottom wall of the second accommodating area 32 inclines downward toward 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 accumulated in the second accommodating area 32 with smaller capacity can be avoided.

Fig. 7 is a schematic structural view of an evaporation pan according to another embodiment of the present invention. In other embodiments, the evaporation pan 30 includes a main receiving area 31 'for receiving the condensed water discharged from the first drain pipe 41 and a connection flow passage 33' for receiving the condensed water discharged from the second drain pipe 42, and the connection flow passage 33 'communicates with the main receiving area 31'. 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 flow passage 33' form two receiving areas of the evaporating dish 30.

Because of the restriction in space, connecting runner 33' is elongated shape usually, and the ability of holding the comdenstion water is very limited, for this reason, the utility model discloses further set up connecting runner 33' to be higher than main holding area 31' in vertical height at vertical height, from this, the comdenstion water that connecting runner 33' received can directly converge main holding area 31', and can not pile up in connecting runner 33', and the size requirement to connecting runner 33' is lower, 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 channel 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 channel 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 channel 33 'has a tendency to flow toward the main accommodating area 31'.

In some embodiments, one end of the connection flow path 33' is open and communicates with the main receiving area 31' to form an open end of the connection flow path 33', and the other end of the connection flow path 33' is provided with an end plate 331 to form a closed end of the connection flow path 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 to say, the bottom wall of the connecting flow channel 33' is inclined downwards towards the main accommodating area 31', which is beneficial for the condensed water in the connecting flow channel 33' to flow to the main accommodating area 31' more quickly, and the condensed water is prevented from accumulating in the connecting flow channel 33' with smaller capacity.
