At present, the refrigeration system in the refrigerator includes an evaporator, a fan, a compressor, and a connecting pipe. The evaporator and fan are usually installed in the space between the back of the freezer and the box, and the compressor is usually installed in the bottom space of the refrigerator.

However, in some side-by-side refrigerators, limited by the width of the freezer compartment, the height of the evaporator is relatively large, resulting in a larger space occupied by the evaporator and reducing the storage space of the refrigerator.

FIG. 1 is a structural diagram of a refrigerator according to an embodiment of the present disclosure, and FIG. 2 is a structural diagram of a refrigerator according to an embodiment of the present disclosure after the door body is opened.

As shown in FIG. 1 and FIG. 2 , the refrigerator 100 includes a box body 105 , a box liner 110 and a door body 120 , the box body 105 has an opening 106 , the box liner 110 is arranged inside the box body 105 , and the box liner 110 is separated by left and right The form defines the freezing compartment 111 and the refrigerating compartment 112 , and the door body 120 is pivotally connected at the opening 106 and is used to open or close the freezing compartment 111 and the refrigerating compartment 112 .

It should be understood that the positions of the freezing compartment 111 and the refrigerating compartment 112 can be interchanged, which is not limited here.

6 is a side cross-sectional view of a freezing compartment of a refrigerator according to an embodiment of the present disclosure. As shown in FIGS. 2 and 6 , the tank 110 has a protruding portion 113 and a main body portion 114 , and the protruding portion 113 extends from the main body portion 114 to a side away from the opening 106 .

In some embodiments, the tank 110 includes a freezer tank 115 and a refrigerator tank 116 on which the protrusions 113 are disposed.

In some embodiments, as shown in FIG. 2, the tank 110 includes a freezer tank 115 and a refrigerator tank 116, which define a freezer compartment 111 and a refrigerator compartment 112, respectively.

In some embodiments, as shown in FIG. 6 , the freezer compartment 115 includes a protrusion 113 and a main body 114 . Since the protruding portion 113 extends away from the opening 106 , the distance between the position of the protruding portion 113 and the opening 106 on the side wall of the freezing box 115 away from the opening 106 becomes larger, thereby increasing the storage space of the freezing box 115 .

In some embodiments, the above-mentioned refrigerator 100 further includes a refrigeration system, through which cold air is delivered to the freezing compartment 111 and the refrigerating compartment 112 for refrigeration.

Illustratively, the refrigeration system includes an evaporator 130 and a fan 140 . Both the evaporator 130 and the fan 140 are installed on the side of the main body 114 away from the opening 106 , and the two are generally arranged in a vertical direction. Here, the vertical direction is a direction perpendicular to the ground where the refrigerator 100 is located.

The sum of the heights of the evaporator 130 and the fan 140 is smaller than the difference between the heights of the main body portion 114 and the protruding portion 113 , that is, the evaporator 130 and the fan 140 are both installed below the protruding portion 113 . In this way, the storage space of the freezer tank 115 can be enlarged, thereby increasing the volume space of the refrigerator 100 .

It should be noted that the height of any of the above components refers to the overall dimension along the vertical direction. As shown in FIG. 6 , the height of the evaporator 130 is h1, the height of the fan 140 is h2, the height of the protrusion 113 is h3, the height of the main body 114 is h4, the evaporator 130, the fan 140, the protrusion 113 and the main body The height relationship of 114 is: h1+h2<h4-h3.

Specifically, please refer to FIGS. 3 to 6 , FIG. 3 is a structural diagram of a refrigeration system of a refrigerator according to an embodiment of the present disclosure, FIG. 4 is a side view of a freezer compartment of a refrigerator according to an embodiment of the present disclosure, and FIG. The side view of the refrigerator compartment of the refrigerator of the disclosed embodiment, the arrows in FIGS. 3 , 4 and 5 indicate the direction of air flow in the refrigerator 100 .

As shown in FIG. 6 , the refrigerator 100 further includes an air duct cover 205 disposed between the freezer box 115 and the box body 105 . A first air duct 210 is formed between the air duct cover 205 and the protruding portion 113 , a second air duct 220 is formed between the air duct cover 205 and the main body 114 , and the evaporator 130 and the fan 140 are arranged in the second air duct 220 . By arranging the first air duct 210 and the second air duct 220 , it is convenient to control the flow direction of the air in the refrigerator 100 after the evaporator 130 is cooled.

In some embodiments, as shown in FIG. 3 , FIG. 5 and FIG. 6 , an air supply port 117 is opened at the top of the refrigerator compartment 112 , and an air return port 118 is opened at the bottom. The air supply port 117 communicates with the first air duct 210 , and the air return port 118 communicates with the second air duct 220 . The air returning from the air return port 118 to the second air duct 220 reaches the evaporator 130 and continues to exchange heat with the evaporator 130 to form a cold air circulation. A damper 150 is provided at the air supply port 117 , and the damper 150 can open and close the air supply port 117 .

Since the freezing chamber 111 needs more cooling capacity than the refrigerating chamber 112 , whether the cold air enters the refrigerating chamber 112 can be controlled through the damper 150 . In this way, when the refrigerating chamber 112 reaches the predetermined temperature, the damper 150 can close the air supply port 117 to avoid affecting the temperature of the refrigerating chamber 112 when the freezing chamber 111 needs cooling capacity.

It should be noted that, since the air duct cover 205 is located between the freezer tank 115 and the box body 110 , the air supply port 117 on the refrigerating chamber 112 can generally communicate with the first air duct 210 through the air supply duct 230 .

In some embodiments, as shown in FIG. 4 , the freezer compartment 111 is provided with an air inlet 221 and an air outlet 222 . The air inlets 221 are generally disposed on the side wall of the freezing chamber 111 away from the opening 106 , and the number of the air inlets 221 may be multiple, so as to deliver cold air to the freezing chamber 111 from different positions. The air outlet 222 is generally located at the bottom of the freezer compartment 111, and the air from the air outlet 222 reaches the evaporator 130, and continues to exchange heat with the evaporator 130 to form a cold air circulation.

In this way, when the refrigerator 100 is refrigerating, the evaporator 130 cools the surrounding air through heat exchange, and then the fan 140 transports the cooled air to the freezing chamber 111 and the refrigerating chamber 112 through the first air duct 210 and the second air duct 220 .

In some embodiments, as shown in FIG. 6 , the evaporator 130 is disposed in the second air duct 220 and below the fan 140 . Specifically, please refer to FIG. 7, which is a structural diagram of an evaporator according to an embodiment of the present disclosure.

As shown in FIG. 7 , the evaporator 130 includes a plurality of fins 310 , a first side plate 320 and a second side plate 325 disposed opposite to both sides of the plurality of fins 310 , and a first side plate 320 and a second side plate 325 passing through the plurality of fins 310 . Evaporation tubes 330 of one side plate 320 and the second side plate 325 . The fins 310 , the first side plate 320 and the second side plate 325 are provided with first through holes through which the evaporation tubes 330 pass.

In some examples, the evaporation tubes 330 are attached to the first through holes on the fins 310 , that is, the evaporation tubes 330 are closely connected with the fins 310 , which can effectively expand the contact area between the evaporation tubes 330 and the fins 310 and improve the fins 310 The heat transfer efficiency with the evaporating tube 330 and the overall cooling efficiency of the evaporator 130 can reduce the volume of the evaporator 130 under the premise of ensuring the cooling effect, thereby shortening the second air duct 220 and extending the first air duct 210, The volume and space utilization of the refrigerator 100 are improved.

For example, the evaporation tube 330 may be processed by means of tube expansion, etc., so as to fit with the first through holes on the fins 310 . Here, the tube expansion processing method generally refers to the installation method of the evaporation tube 330 and the fins 310 . When installing the evaporation tube 330 and the fins 310, first pass the evaporation tube 330 through the first through hole on the fin 310, and the size of the evaporation tube 330 is smaller than the size of the first through hole, which is convenient to pass through. Then, a spherical piece with a size slightly larger than the size of the first through hole can be used to pass through the evaporation tube 330 or other expansion methods to slightly increase the diameter of the evaporation tube 330, so that the evaporation tube 330 and the fins 310 are closely connected at the contact point , to ensure the heat transfer effect.

It should be understood that the above-mentioned way of expanding the tube is only an optional way to realize the bonding of the evaporation tube 310 and the first through hole, and the embodiment of the present disclosure is not limited to this, as long as the bonding of the evaporation tube 310 and the first through hole can be achieved. That's it.

8 is a structural diagram of an evaporator of a refrigerator according to another embodiment of the present disclosure, and FIG. 9 is a structural diagram of an evaporator of a refrigerator according to still another embodiment of the present disclosure. In some embodiments, as shown in FIG. 7 to FIG. 9 , the evaporation tube 330 includes a plurality of straight pipe sections 331 and a plurality of curved pipe sections 332 , and the shape of the curved pipe sections 332 may be U-shaped or C-shaped. Each adjacent two straight pipe sections 331 of the plurality of straight pipe sections 331 are connected to one curved pipe section 332 of the plurality of curved pipe sections 332 , so as to form the entire evaporation tube 330 .

In some embodiments, as shown in FIG. 7 , the plane of the plurality of straight pipe sections 331 is parallel or approximately parallel to the opening 106 , that is, perpendicular or approximately perpendicular to the ground. In this way, the parallel or approximately parallel arrangement can shorten the overall length of the evaporation tube 330 compared to the way in which the evaporation tube 330 is disposed inclined to the opening 106 (ie, inclined to the ground), thereby shortening the distance that the refrigerant flows in the evaporation tube 330 , thereby shortening the circulation time of the refrigerant, which is beneficial to improve the evaporation efficiency of the evaporator 130 , thereby further reducing the volume of the evaporator 130 .

In some embodiments, as shown in FIGS. 7 to 9 , the first side plate 320 includes a first sub-plate 321 and a second sub-plate 322 , and the fins 310 between the first sub-plate 321 and the second side plate 325 The number is greater than the number of the fins 310 between the second sub-plate 322 and the second side plate 325 .

In some embodiments, the orthographic projection of the first sub-board 321 on the second side board 325 and the orthographic projection of the second sub-board 322 on the second side board 325 have an overlapping area. In this overlapping area, the evaporation tube 330 passes through the first sub-plate 321 and the second sub-plate 322 at the same time, so as to provide an integral fixation for the evaporator 130 .

Here, the lengths of the first sub-board 321 and the second sub-board 322 may depend on the specific conditions in the refrigerator 100, as long as the lateral space (ie, the space of the box 110 in the horizontal direction) is used as much as possible to accommodate the fins 310 as much as possible , which is not limited here.

It should be understood that, although only the case where the first side panel 320 includes two sub panels is shown in FIGS. 7 to 9 , in other embodiments, the second side panel 325 may also include two or more sub panels. Whether the second side plate 325 includes sub-plates depends on the specific structure in the refrigerator 100, that is, if there is space on both sides of the evaporator 130 to allow more fins 310 to be provided, but if present, the second side plate 325 is provided as An integral side plate, if a part of the second side plate 325 interferes with other structures and the position of the entire second side plate 325 cannot be changed, the second side plate 325 can be made into a structure including a plurality of sub-plates , so that a portion of the sub-plates can be repositioned, thereby allowing the evaporator 130 to be arranged to include more fins 310 .

In other embodiments, the first sub-board 321 and the second sub-board 322 may be connected to each other. As shown in FIG. 8 , the first side plate 320 further includes a connecting portion 323 connected to the first sub-board 321 and the second sub-board 322 , and the first sub-board 321 and the second sub-board 322 are connected as a whole through the connecting portion 323 , so as to facilitate the installation of the first side plate 320 .

In some embodiments, as shown in FIG. 9 , the orthographic projection of the first sub-board 321 on the second side board 325 does not overlap with the orthographic projection of the second sub-board 322 on the second side board 325 , and the first The distance between the sub-board 321 and the second side plate 325 is greater than the distance between the second sub-board 322 and the second side plate 325, and the connecting portion 323 is a straight plate, so that the upper surface of the connecting portion 323 is an inclined plane, The condensed water generated on the fins 310 located above the connecting portion 323 can flow downward along the connecting portion 323 to prevent the condensed water from accumulating on the connecting portion 323 .

In some embodiments, the first sub-board 321 , the second sub-board 322 and the connecting portion 323 are integral structures, which facilitates the installation of the first side plate 320 .

In some embodiments, FIG. 10 is a structural view of a first side panel of an evaporator of a refrigerator according to an embodiment of the present disclosure. As shown in FIG. 10 , the connecting portion 323 is provided with a second through hole 324 , and the second through hole 324 penetrates the connecting portion 323 along the thickness direction of the connecting portion 323 (as shown by the arrow in FIG. 10 ) to communicate with the connecting portion 323 . The upper space and the lower space of the connecting portion 323 .

In this way, on the one hand, the air in the second air duct 220 can pass through the connecting portion 323 through the second through hole 324, thereby improving the overall efficiency of the cold air circulation; Flow through the second through hole 324 to the water collecting box at the bottom of the evaporator 130, so as to prevent water or frost from accumulating at the connecting part 323 and being continuously frozen and wasting the power of the evaporator 130, which is beneficial to improve the overall utilization rate of the evaporator 130 .

In some embodiments, the air return port 118 at the bottom of the refrigerator container 116 communicates with the second air duct 220 , and the air in the refrigerator compartment 112 flows back into the second air duct 220 from the air return port 118 to be cooled again.

In some embodiments, as shown in FIGS. 5 , 6 and 7 , the arrangement density of the fins 310 near the air return port 118 is smaller than the arrangement density of the fins 310 farther away from the air return port 118 , closer to the air return port 118 . The fins 310 at the fins 310 are more sparsely arranged, so that the air flowing back to the second air duct 220 from the air return port 118 is easier to pass through the fins 310 near the air return port 118, so as to avoid the accumulation of air frost between the fins 310, affect the flow of air.

In some embodiments, FIG. 11 is a structural diagram of a second side panel of an evaporator of a refrigerator according to an embodiment of the present disclosure. As shown in FIGS. 5 , 8 and 11 , the second side panel 325 is disposed near the air return port 118 . , a gap is left between the second side plate 325 and the bottom of the second air duct 220 so that air flows into the second air duct 220 . The second side plate 325 is provided with a ventilation hole 340 near the air return port 118 .

In this way, when the air in the refrigerating compartment 112 flows out from the air return port 118, the air can flow into the second air duct 220 through the ventilation hole 340 and the bottom gap.

By arranging the ventilation holes 340 on the second side plate 325 close to the air return port 118 , the generation of air between the second side plate 325 and the side wall of the second air duct 220 can be avoided when the air flows back from the refrigerating compartment 112 to the second air duct 220 . The eddy current affects the air circulation rate, which is beneficial to improve the overall efficiency of the cooling air circulation and improve the cooling effect of the refrigerator 100 .

It should be understood that the first side plate 320 may also be disposed close to the air return port 118 , and which of the first side plate 320 and the second side plate 325 is closer to the air return port 118 depends on the specific structure of the tank 110 and is not limited here.

In other embodiments, the first side plate 320 is disposed close to the air return port 118 , and a gap is left between the first side plate 320 and the bottom of the second air duct 220 so that air flows into the second air duct 220 . The first side plate 320 is provided with a ventilation hole 340 near the air return port 118 .

By arranging the ventilation holes 340 on the first side plate 320 near the tuyere 118 , eddy currents can be prevented from being generated between the first side plate 320 and the side walls of the second air duct 220 when the air flows from the refrigerating compartment 112 back to the second air duct 220 . This affects the air circulation rate, thereby helping to improve the overall efficiency of the cold air circulation and improve the cooling effect of the refrigerator 100 .

In some embodiments, as shown in FIG. 8 , the plurality of fins 310 generally includes a plurality of fin groups 350 arranged in a vertical direction, and each fin group 350 includes a plurality of fins arranged in a horizontal direction 310 , the arrangement density of the fins 310 in at least one fin group 350 of the plurality of fin groups 350 away from the protrusion 113 is smaller than the arrangement density of the fins 310 in the remaining fin groups 350 .

Specifically, referring to FIG. 8 again, the plurality of fin groups 350 includes a first fin group 351 and a second fin group 352 . The first fin group 351 is located above the second fin group 352 , that is, the first fin group 351 is closer to the protrusion 113 than the second fin group 352 . Meanwhile, the arrangement density of the fins 310 in the first fin group 351 is greater than the arrangement density of the fins 310 in the second fin group 352 .

Through the above arrangement, when the air passes through the plurality of fin groups 350 from the bottom of the evaporator 130, it will first pass through the fins 310 which are arranged sparsely in the second fin group 352. At this time, there is more moisture in the air. , therefore, it is easier for frost to form on the fins 310 . The sparse arrangement of the fins 310 makes the space between the fins 310 larger, which can effectively prevent frost from completely blocking the space between the fins 310 and affect the effect of cold air circulation. After passing through the second fin group 352, the moisture in the air is reduced due to frost, and then passes through the first fin group 351 with a higher density, so that the air and the evaporator 130 can be fully exchanged with heat.

For example, the first fin group 351 includes a plurality of groups of fins 310 arranged in a vertical direction, and the second fin group 352 includes two groups of fins 310 arranged in a vertical direction.

In some embodiments, the plurality of fins 310 may further include more fin groups 350 , and the arrangement density of the fins 310 in the plurality of fin groups 350 decreases sequentially along the direction away from the protruding portion 113 . Specifically, as shown in FIG. 9 , the plurality of fins 310 include a first fin group 351 , a second fin group 352 and a third fin group 353 that are sequentially arranged downward in the vertical direction, that is, the first fin group The fin group 351 , the second fin group 352 and the third fin group 353 are arranged in a direction away from the protrusion 113 , and the first fin group 351 , the second fin group 352 and the third fin group 353 The arrangement density of the fins 310 decreases sequentially.

Through the above arrangement, when the air flows in the direction close to the protruding part 113 in the second air duct 220, the air passes through the third fin group 353, the second fin group 352 and the first fin group 351 in sequence, and the fin group 351. The arrangement density of the fins 310 in the 350 increases sequentially, so that the water vapor in the air passing through the third fin group 353 , the second fin group 352 and the first fin group 351 decreases successively, thereby improving the evaporator 130 In order to avoid the frost on the third fin group 353 away from the protrusion 113, the air may be blocked from the flow of air. The arrangement density of the fins 310 in the plurality of fin groups 350 decreases sequentially along the direction away from the protruding portion 113, which can not only prevent frost from accumulating on the bottom of the evaporator 130 and affect the air flow, but also ensure that the air and the evaporator 130 fully conduct heat exchange, and the cooling effect is better.

For example, the first fin group 351 includes multiple groups of fins 310 arranged in the vertical direction, the second fin group 352 includes four groups of fins 310 arranged in the vertical direction, and the third fin group 353 includes vertical fin groups 310. Three sets of fins 310 arranged in a straight direction.

It should be understood that the number of the fin groups 350 and the arrangement density of the fins 310 may depend on the specific situation, as long as the cooling demand of the refrigerator 100 can be met, which is not limited here.

In the embodiment of the present disclosure, the protruding portion 113 extending away from the opening 106 is provided in the freezer compartment 115 of the refrigerator 100 , and the sum of the heights of the fan 140 and the evaporator 130 is smaller than the height of the main body portion 114 and the protruding portion 113 . The difference in height can expand the space of the freezer tank 115 and increase the volume space of the refrigerator 100 .

The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical scope disclosed in the present disclosure, think of changes or replacements, should cover within the scope of protection of the present disclosure.
