Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, and in particular to a refrigeration device. Background Art

[0002] At present, refrigeration equipment such as refrigerators and freezers are widely used in commercial and household fields because they can store items at low temperatures. The refrigeration principle generally adopts direct cooling and air cooling. Among them, air cooling is more popular among users. Air-cooled freezers circulate the air in the freezer and flow through the evaporator, thereby reducing the temperature of the air and further reducing the temperature in the freezer. The water contained in the refrigerated object easily becomes water vapor at low temperatures and adheres to the evaporator. Therefore, for air-cooled freezers, defrosting the evaporator and draining after defrosting are very important.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0004] In the refrigerators in the related art, an evaporator must be installed in the refrigerator to achieve refrigeration. The evaporator needs to be defrosted regularly to avoid clogging of the evaporator. When the evaporator is not drained smoothly, the defrost water is likely to remain in the evaporator compartment, thereby affecting the normal use of the evaporator and the refrigeration effect of the refrigerator.

[0061] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0062] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0063] Combination Figures 14 to 21 As shown, the embodiment of the present disclosure provides a refrigeration device, including an evaporator compartment 50 and an evaporator 52. The bottom wall of the evaporator compartment 50 is provided with a drainage surface 54 and a drainage port 27. The drainage surface 54 is inclined in both the left-right direction and the front-back direction, and the drainage port 27 is provided at the lowest point of the drainage surface 54. The evaporator 52 is provided in the evaporator compartment 50 and is used for refrigeration of the refrigeration device. Among them, the defrost water generated by the evaporator 52 is discharged from the evaporator compartment 50 through the drainage port 27.

[0064] With the refrigeration device provided by the embodiment of the present disclosure, the drainage surface 54 is inclined in both the left-right direction and the front-back direction, and the drainage port 27 is formed at the lowest point of the drainage surface 54, so that the defrost water in the evaporator compartment 50 flows obliquely from front to back or from back to front to the drainage port 27, and the defrost water in the evaporator compartment 50 flows obliquely from left to right or from right to left to the drainage port 27, making the discharge process of the defrost water smoother, improving the drainage effect of the evaporator compartment 50, and then being able to ensure the normal operation of the evaporator 52, thereby ensuring the refrigeration effect of the refrigeration device. Moreover, the drainage surface 54 has a simple structure and saves costs.

[0065] Optionally, the refrigeration device is a freezer 10 or a refrigerator. The refrigeration device also includes a compressor, a condenser and a throttling device, and the compressor, the condenser, the throttling device and the evaporator 52 are connected through pipelines to form a refrigeration system of the refrigeration device. The refrigeration device also includes a refrigerant, which circulates in the pipelines of the refrigeration system for refrigeration.

[0066] Optionally, combined Fig.15 As shown, the refrigeration device also includes an inner tank 20, and the evaporator compartment 50 is arranged in the inner tank 20. There are multiple drainage surfaces 54, and the multiple drainage surfaces 54 include a first drainage surface 541 and a second drainage surface 542. The first drainage surface 541 is connected to the rear wall 29 of the inner tank 20, and is inclined downward in the direction from the back to the front and forms a first oblique edge 5411 on the side away from the rear wall 29. The second drainage surface 542 is connected to the front wall 28 of the inner tank 20, and is inclined downward in the direction from the front to the back and forms a second oblique edge 5421 on the side away from the front wall 28. Among them, the second oblique edge 5421 is connected to the first oblique edge 5411, and the drainage port 27 is provided at the connection between the first oblique edge 5411 and the second oblique edge 5421.

[0067] In this way, the drainage surface 54 is designed to be multiple, and the position of the drainage port 27 can be adjusted by the connection position of the multiple drainage surfaces 54 to meet the needs of various products. Moreover, compared with the bottom wall formed by a single drainage surface 54 that is inclined downward from the back to the front or from the front to the back, when the inclination angle and inclination direction of the first drainage surface 541 or the second drainage surface 542 are the same as those of the single drainage surface 54, the lowest point of the bottom wall formed by the first drainage surface 541 and the second drainage surface 542 is higher than the lowest point of the single drainage surface 54, which can occupy less insulation layer and achieve better insulation effect of the refrigeration equipment.

[0068] It is understandable that the refrigeration equipment also includes a box shell, and a foaming liquid is filled between the box shell and the inner liner 20 to form an insulation layer. The evaporator compartment 50 is arranged on the bottom wall of the inner liner 20, and the bottom wall of the evaporator compartment 50 is part of the bottom wall of the inner liner 20, that is, the bottom of the bottom wall of the evaporator compartment 50 is also filled with an insulation layer.

[0069] The first drainage surface 541 is inclined downward from the back to the front, and the second drainage surface 542 is inclined downward from the front to the back. Therefore, the connection between the first inclined edge 5411 and the second inclined edge 5421 is the lowest edge of the bottom wall of the evaporator compartment 50. The drainage port 27 is arranged on the lowest edge, which can make the discharge process of the defrost water in the evaporator compartment 50 smoother, improve the drainage effect of the evaporator compartment 50, and further ensure the normal operation of the evaporator 52, thereby ensuring the refrigeration effect of the refrigeration equipment. Moreover, the double drainage surface 54 has a simple structure and saves costs.

[0070] Optionally, the refrigeration device further includes a compressor compartment 60, which is arranged side by side with the evaporator compartment 50 in the left-right direction. The first drainage surface 541 and the second drainage surface 542 are both inclined in the left-right direction toward the direction where the compressor compartment 60 is located, and the drainage port 27 is located at the connection between the first oblique edge 5411 and the second oblique edge 5421, close to one end of the compressor compartment 60.

[0071] Optionally, the compressor compartment 60 includes a drain pipe and an evaporation dish. One end of the drain pipe is connected to the drain port 27, and the other end is connected to the evaporation dish, so as to drain the defrosted water in the evaporator compartment 50 into the evaporation dish.

[0072] The compressor compartment 60 and the evaporator compartment 50 are arranged side by side in the left-right direction, and the defrost water in the evaporator compartment 50 flows into the drain pipe in the compressor compartment 60 through the drain port 27, and then flows into the evaporation dish for evaporation. The first drain surface 541 and the second drain surface 542 are both inclined toward the compressor compartment 60 in the left-right direction, so that the lowest point of the first inclined edge 5411 or the second inclined edge 5421 is just close to one end of the compressor compartment 60. The drain port 27 is arranged at the lowest point of the lowest side of the bottom wall of the evaporator compartment 50, which can make the discharge process of the defrost water in the evaporator compartment 50 smoother, improve the drainage effect of the evaporator compartment 50, and then ensure the normal operation of the evaporator 52, thereby ensuring the refrigeration effect of the refrigeration equipment.

[0073] Optionally, combined Figures 16 to 18 As shown, the plurality of drainage surfaces 54 further include a third drainage surface 543, which is disposed between the first drainage surface 541 and the second drainage surface 542. The third drainage surface 543 includes a third oblique side 5431 and a fourth oblique side 5432 opposite to the third oblique side 5431, wherein the third oblique side 5431 is connected to the first oblique side 5411, and the fourth oblique side 5432 is connected to the second oblique side 5421, so that the first drainage surface 541 and the second drainage surface 542 are connected.

[0074] In this way, the bottom wall of the evaporator cabin 50 is composed of the first drainage surface 541, the second drainage surface 542 and the third drainage surface 543. The third drainage surface 543 connects the first drainage surface 541 and the second drainage surface 542. In this way, the height of the lowest point of the bottom wall of the evaporator cabin 50 can be further improved, and the distance between the bottom wall and the box shell is increased. The thickness of the insulation layer between the bottom wall and the box shell is thicker, and the insulation effect of the refrigeration equipment is better.

[0075] Optionally, the third drainage surface 543 is in a triangular shape, the base of the triangle is located on the side of the evaporator compartment 50 away from the compressor compartment 60, the vertex is located on the side of the evaporator compartment 50 close to the compressor compartment 60, and the third drainage surface 543 is inclined along the base of the triangle toward the vertex. The drainage port 27 is provided at the vertex of the triangle.

[0076] In this way, the triangular-shaped third drainage surface 543 is inclined toward the compressor compartment 60 in the left-right direction, and the inclination direction in the left-right direction is consistent with the first drainage surface 541 and the second drainage surface 542 .

[0077] Optionally, the evaporator 52 is horizontally placed in the evaporator cabin 50 , and at least three points on the evaporator 52 are respectively in contact with the first drainage surface 541 , the second drainage surface 542 , and the third drainage surface 543 to support the evaporator 52 .

[0078] In this way, the evaporator 52 can be stably supported without the need for an additional bracket, and the evaporator 52 can be placed horizontally, minimizing the obstruction of the evaporator 52 to the flow path of the defrost water, and the drainage of the evaporator compartment 50 is smoother.

[0079] Optionally, combined Figures 19 to 21 As shown, the plurality of drainage surfaces 54 further include a fourth drainage surface 544, which is disposed between the first drainage surface 541 and the third drainage surface 543, and the fourth drainage surface 544 connects the first oblique side 5411 and the third oblique side 5431. The first oblique side 5411 is higher than the third oblique side 5431, and the second drainage surface 542, the third drainage surface 543 and the fourth drainage surface 544 jointly define a drainage portion 55, and the drainage port 27 is located at the lowest point of the drainage portion 55.

[0080] The first bevel 5411 is higher than the third bevel 5431, and the fourth drainage surface 544 connects the first bevel 5411 and the third bevel 5431, that is, the fourth drainage surface 544 is extended in the up-down direction, and the first drainage surface 541 is higher than the third drainage surface 543, so that the defrosted water at the lowest point of the first drainage surface 541 can also flow smoothly into the drainage portion 55, reducing water accumulation. The defrosted water in the evaporator cabin 50 first flows into the drainage portion 55, and then flows out of the evaporator cabin 50 through the drainage port 27, avoiding the problem of water accumulation and freezing on one side of the first drainage surface 541 and the second drainage surface 542 close to the compressor cabin 60.

[0081] Optionally, the evaporator 52 is placed in contact with the first drainage surface 541 and is located above the drainage portion 55 .

[0082] In this way, the evaporator 52 is closely attached to the first drainage surface 541, and in the air return process of the refrigeration equipment, the utilization rate of the evaporator 52 is higher and the power consumption is lower. The evaporator 52 is arranged above the drainage portion 55, so that the water vapor attached to the surface of the evaporator 52 above the drainage portion 55 can directly drip onto the drainage portion 55 and be discharged from the evaporator compartment 50 through the drainage port 27, thereby improving the drainage efficiency.

[0083] Optionally, combined Fig.14 As shown, the number of the drainage surface 54 is one, and the drainage port 27 is located at the end corner of the drainage surface 54 .

[0084] The number of drainage surfaces 54 is one, and the bottom wall of the evaporator compartment 50 is composed of only one drainage surface 54, which has a simple structure, reduces the difficulty of the process, and saves costs. Assuming that the single drainage surface 54 is inclined downward from the back to the front and inclined to the right from the left to the right, then the lowest point of the single drainage surface 54 is at the end corner in the right front of it, and the drainage port 27 is arranged here, which can meet the requirement that the drainage port 27 is lower than any point on the single drainage surface 54.

[0085] Optionally, the evaporator compartment 50 further includes a vertically arranged side wall 56, the side wall 56 connects the bottom wall of the evaporator compartment 50 and the top wall of the compressor compartment 60 of the refrigeration equipment, and the side wall 56 separates the evaporator compartment 50 from the compressor compartment 60. The refrigeration equipment further includes a fan 30, which is vertically arranged on the bottom wall of the evaporator compartment 50, and the fan 30 includes a volute. Among them, the top wall of the evaporator compartment 50 is flush with the top wall of the compressor compartment 60, and the height difference between the highest point of the drainage surface 54 where the fan 30 is located and the top wall of the evaporator compartment 50 is equal to the height of the volute.

[0086] The top wall of the evaporator compartment 50 is flush with the top wall of the compressor compartment 60, so that the appearance is more beautiful, and it is more convenient to place things on the top wall of the evaporator compartment 50 and the top wall of the compressor compartment 60. Assuming that the fan 30 is set on the first drainage surface 541, the height of the volute is equal to the height difference between the highest point of the first drainage surface 541 and the top wall of the evaporator compartment 50, so that the fan 30 can be placed vertically and will not protrude from the top wall of the evaporator compartment 50, ensuring that the top wall of the evaporator compartment 50 is always flush with the top wall of the compressor compartment 60, improving the aesthetics. Moreover, when the fan 30 is placed vertically, the wind resistance of the cold air is small, the air volume is large, and the cooling effect of the refrigeration equipment is better.

[0087] Combination Figures 1 to 18 As shown, the embodiment of the present disclosure provides a refrigerator 10, including a box shell, an inner liner 20 and an evaporator compartment 50. The inner liner 20 is arranged in the box shell, and the inner liner 20 includes a first bottom wall 25, a second bottom wall 26 and a sinking structure 236 arranged between the first bottom wall 25 and the second bottom wall 26, the second bottom wall 26 is higher than the first bottom wall 25, and the bottom wall of the sinking structure 236 is lower than the first bottom wall 25. The evaporator compartment 50 is arranged in the sinking structure 236, and a fan 30 is arranged inside the evaporator compartment 50.

[0088] The sinking structure 236 reduces the area occupied by the evaporator compartment 50 in the internal space of the refrigerator 10, thereby improving the volume ratio of the refrigerator 10. Moreover, under the premise of ensuring the volume ratio of the refrigerator 10, the large-sized fan 30 can be vertically arranged in the evaporator compartment 50, and there is no need to tilt the large-sized fan 30 or replace it with a smaller-sized fan 30 as in the related art, thereby reducing the air volume loss, accelerating the refrigeration speed of the refrigerator 10, and improving the refrigeration efficiency of the refrigerator 10.

[0089] Assuming that the fan 30 is arranged along the front-to-back direction, it is understandable that the inclined fan 30 has a larger span in the front-to-back direction, which will occupy the installation space of the evaporator 52, increase the difficulty of installing the evaporator 52 or require replacing the evaporator 52 with a smaller size, thereby reducing the cooling efficiency.

[0090] Moreover, the air outlet of the tilted fan 30 is also tilted, and the span of the air outlet in the front-to-back direction is relatively large. In this way, the thickness of the refrigeration air duct of the refrigerator 10 connected to the air outlet is relatively large, resulting in excessive volume loss of the refrigerator 10, thereby reducing the volume ratio of the refrigerator 10.

[0091] Optionally, the sinking structure 236 includes a receiving portion 2351 and a connecting portion 2352. The receiving portion 2351 is connected to the first bottom wall 25, and the receiving portion 2351 is configured to carry the evaporator compartment 50. The connecting portion 2352 is connected to the receiving portion 2351 and the second bottom wall 26 respectively, and the connecting portion 2352, the second bottom wall 26 and the box shell together form a compressor compartment 60 of the refrigerator 10. The fan 30 is vertically arranged in the evaporator compartment 50, and the height of the connecting portion 2352 is greater than or equal to the height of the fan 30.

[0092] The connecting portion 2352 is respectively connected to the receiving portion 2351 and the second bottom wall 26. The height of the connecting portion 2352 is the height difference between the receiving portion 2351 and the second bottom wall 26. The height of the fan 30 is less than or equal to the height of the connecting portion 2352, that is, the height of the fan 30 is less than or equal to the height difference between the receiving portion 2351 and the second bottom wall 26. In this way, the fan 30 will not protrude from the second bottom wall 26 when it is vertically arranged, affecting the appearance. The vertically placed fan 30 has a small air outlet resistance, a small air volume loss, and a large air volume, which can speed up the refrigeration speed of the refrigerator 10 and improve the refrigeration efficiency of the refrigerator 10. Moreover, it can be ensured that when the fan 30 is placed vertically, the top end of the fan 30 is lower than the second bottom wall 26 or is flush with the second bottom wall 26, thereby ensuring that the top wall of the evaporator compartment 50 can be flush with the second bottom wall 26, reducing the area occupied by the evaporator compartment 50 on the internal space of the refrigerator 10, improving the volume ratio of the refrigerator 10, and making the appearance more flat and beautiful, which is convenient for storing food.

[0093] Optionally, the receiving portion 2351 includes a drainage surface 54, which is disposed on a side surface of the receiving portion 2351 facing the evaporator compartment 50 and forms the bottom wall of the evaporator compartment 50, and the drainage surface 54 is inclined in the front-to-back direction. The top wall of the evaporator compartment 50 is flush with the second bottom wall 26, and the fan 30 is disposed at the highest point of the drainage surface 54, and the height difference between the highest point of the drainage surface 54 and the top wall of the evaporator compartment 50 is greater than or equal to the height of the fan 30.

[0094] The drainage surface 54 is inclined in the front-to-back direction, so that the defrost water discharge process is smoother, and the drainage effect of the evaporator compartment 50 is improved. The fan 30 is set at the highest point of the drainage surface 54 to prevent the defrost water from flowing to the fan 30 and condensing on the surface of the fan 30, which affects the normal operation of the fan 30. The top wall of the evaporator compartment 50 is flush with the second bottom wall 26, and the appearance is smoother and more beautiful, which is convenient for storing food. The height difference between the highest point of the drainage surface 54 and the top wall of the evaporator compartment 50 is greater than or equal to the height of the fan 30, so that the fan 30 can be placed vertically and will not protrude from the top wall of the evaporator compartment 50, ensuring that the top wall of the evaporator compartment 50 is always flush with the second bottom wall 26, improving the aesthetics. Moreover, the fan 30 is placed vertically, the wind resistance of the cold air is small, the air volume is large, and the refrigeration effect of the refrigerator 10 is better.

[0095] Optionally, the drainage surface 54 has an inclination angle a, where a≥5°.

[0096] For example, the inclination angle of the drainage surface 54 from the back to the front is 5°, and the refrigerator 10 also includes an evaporator 52 arranged in the evaporator compartment 50. Setting the inclination angle to 5° will not cause a significant decrease in the installation stability of the evaporator 52 due to an excessively large inclination angle, and can also make the discharge process of the defrost water smoother.

[0097] Optionally, the receiving portion 2351 further includes a drain port 27, and the drain port 27 is disposed at the lowest point of the drain surface 54. The height difference between the drain port 27 and the first bottom wall 25 is b, 0 mm ≤ b ≤ 50 mm.

[0098] The drain port 27 is arranged at the lowest point of the drain surface 54, and the defrost water generated during the operation of the evaporator 52 can flow into the drain port 27 along the inclined drain surface 54, and then be discharged from the evaporator compartment 50, so that the drainage process is smoother.

[0099] It is understandable that the foaming liquid is filled between the inner liner 20 and the box shell to form an insulation layer. The drain port 27 is the lowest point of the sinking structure 236. The maximum height difference between the drain port 27 and the first bottom wall 25 is set to 50 mm, which can ensure that the thickness of the insulation layer between the lowest point of the sinking structure 236 and the box shell meets the requirements of the refrigeration standard, avoid condensation at the bottom of the box body due to the insulation layer being too thin, and affect the temperature of the evaporator compartment 50, and ensure that the fan 30 is placed vertically in the evaporator compartment 50.

[0100] Optionally, b=10 mm, 20 mm, 30 mm or 40 mm.

[0101] In this way, the inner liner 20 of appropriate size can be selected according to the specifications of different fans 30 to meet the cooling requirements. The inner liner 20 can be a spliced ​​inner liner 20, and the sinking structure 236 can be replaced as a universal part.

[0102] It is understandable that when the height difference between the drain port 27 and the first bottom wall 25 is 0, the sinking structure 236 is flush with the first bottom wall 25. At this time, the fan 30 can be replaced with a small-sized one to ensure the vertical placement of the fan 30.

[0103] Optionally, a bend is formed at the connection between the receiving portion 2351 and the connecting portion 2352, the number of the drainage surface 54 is one, and the drainage port 27 is located at the lowest end corner of the bend.

[0104] The number of drainage surfaces 54 is one, and the bottom wall of the evaporator compartment 50 is composed of only one drainage surface 54, which has a simple structure, reduces the process difficulty, and saves costs. The compressor compartment 60 and the evaporator compartment 50 are arranged side by side in the left-right direction, and the connecting portion 2352 separates the compressor compartment 60 and the evaporator compartment 50. The drainage port 27 is arranged at the bend near the connecting portion 2352, so that the defrosted water generated during the defrosting process of the evaporator 52 is discharged from the evaporator compartment 50 through the drainage port 27, and flows into the evaporation dish in the compressor compartment 60 through the drainage pipe in the compressor compartment 60, thereby avoiding quality accidents, and making full use of the high temperature of the compressor compartment 60 to evaporate the defrosted water in the evaporation dish, thereby saving energy. Assuming that the single drainage surface 54 is inclined downward from the back to the front, then, setting the drainage port 27 at the front end angle of the bend can meet the requirement that the drainage port 27 is lower than any point on the bend.

[0105] Optionally, the refrigerator 10 also includes a heating device, which is arranged below the evaporator 52 and the fan 30 of the refrigerator 10. The sum of the heights of the heating device and the evaporator 52 is c, the sum of the heights of the heating device and the fan 30 is d, and the height of the evaporator compartment 50 is e, wherein c≤e, and d≤e.

[0106] The sum of the heights of the heating device and the evaporator 52 is c, c≤e. In this way, it can be ensured that after the heating device and the evaporator 52 are installed in the sinking structure 236, the highest point of the evaporator 52 does not exceed the plane where the second bottom wall 26 is located; the sum of the heights of the heating device and the fan 30 is d, d≤e. In this way, it can be ensured that after the heating device and the fan 30 are installed in the sinking structure 236, the highest point of the fan 30 does not exceed the plane where the second bottom wall 26 is located, thereby ensuring that the top wall of the evaporator compartment 50 is always flush with the second bottom wall 26, the appearance is more beautiful, and the occupancy of the internal volume of the refrigerator 10 is reduced, thereby improving the volume ratio of the refrigerator 10.

[0107] Combination Figure 1-13As shown, the embodiment of the present disclosure also provides a refrigerator 10, including a box shell, an inner liner 20 and a first cover plate 41. The box shell defines an installation space, the inner liner 20 is arranged in the installation space, and the inner liner 20 surrounds a refrigeration space. The inner liner 20 includes a front wall 28 and a rear wall 29 arranged opposite to each other, and the front wall 28 and / or the rear wall 29 are provided with a vertical air duct groove 231, and the air duct groove 231 is recessed from the inner liner 20 toward the box shell. The first cover plate 41 is arranged in the air duct groove 231 and is located in the refrigeration space. An air outlet cavity 414 is provided on the left and / or right side of the first cover plate 41, and the air outlet cavity 414 protrudes toward the refrigeration space in a direction away from the air duct groove 231. Among them, a first air outlet 411 for discharging air to the left and / or right is formed between the air outlet cavity 414 and the air duct groove 231.

[0108] In the refrigerator 10 provided by the embodiment of the present disclosure, vertical air duct grooves 231 are arranged on the front wall 28 and the rear wall 29 of the inner tank 20, the first cover plate 41 covers the air duct groove 231, and the air outlet cavity 414 is protruded on the side of the first cover plate 41 facing the refrigeration space. The protruding air outlet cavity 414 can store more cold air, and a first air outlet 411 is formed between the air outlet cavity 414 and the air duct groove 231. In this way, the cold air in the air duct groove 231 can flow to the left and / or right into the refrigeration space through the first air outlet 411, and the distance from the cold air to the left and right sides of the refrigeration space can be balanced. The cold air is distributed more evenly, the temperature difference in the refrigeration space is reduced, the temperature uniformity in the refrigeration space is improved, the electricity bill is saved, and the refrigeration speed of the refrigerator 10 is improved.

[0109] Optionally, combined Figures 22 to 25 As shown, there are multiple first air outlets 411 , and the shape of the first air outlets 411 is triangular, rectangular or hexagonal. The multiple first air outlets 411 of triangle, rectangle or hexagon are arranged on the air outlet cavity 414 at intervals along the vertical direction.

[0110] In this way, by arranging a plurality of first air outlets 411 at different heights on the left side and / or right side of the first cover plate 41, the cooling capacity can be distributed more evenly in different height intervals of the storage cavity, thereby reducing the temperature difference in the storage cavity, improving the temperature uniformity in the storage cavity, and shortening the refrigeration time to reach the set refrigeration temperature, thereby increasing the refrigeration efficiency.

[0111] It is understandable that the position of the first air outlet 411 on the left side can be flush with the position of the first air outlet 411 on the right side, or can be staggered, and the shape of the first air outlet 411 on the left side can be the same as or different from the shape of the first air outlet 411 on the right side. The shape of the first air outlet 411 includes but is not limited to a triangle, a rectangle, and a hexagon, and other shapes such as a circle, a star, a prism, etc. are all possible, which are not listed here one by one.

[0112] The shape of the first air outlet 411 is a triangle, a rectangle or a hexagon. A plurality of first air outlets 411 of a triangle, a rectangle or a hexagon are arranged at intervals on the air outlet cavity 414 along the vertical direction. In this way, not only can the shape of the first air outlet 411 be enriched, but also the wind direction can be standardized. Within a suitable pore range, the denser the pores of the first air outlet 411, the more conducive it is to standardize the wind direction. For example, Fig.25 The hexagonal first air outlet 411 is shown. According to user needs, combined with Fig. 22 and Fig.23 The first air outlet 411 may be arranged in a single row and spaced apart in the vertical direction, combined with Fig.24 and Fig.25 The first air outlets 411 may also be arranged in multiple rows in parallel and spaced apart in the vertical direction.

[0113] Optionally, the refrigerator 10 further includes a fan cavity 31 and a fan 30. The fan cavity 31 is disposed below the air duct groove 231 and communicates with the air duct groove 231, and the fan cavity 31 includes a second cover plate 42, which is connected to the first cover plate 41 and protrudes toward the inner side of the liner 20. The fan 30 is disposed in the fan cavity 31 and is configured to supply air to the air duct groove 231.

[0114] Optionally, the second cover plate 42 includes a first sub-plate 422 and a second sub-plate 423. The first sub-plate 422 covers the fan 30. The second sub-plate 423 connects the first sub-plate 422 and the first cover plate 41, and is inclined from the first sub-plate 422 to the first cover plate 41 to guide the cold air in the fan cavity 31 to flow into the air duct groove 231.

[0115] In this way, a wind path structure that is convex at first and concave at the end is formed, and the second sub-plate 423 acts as a guiding slope to guide the cold air in the fan cavity 31 to flow smoothly into the air duct groove 231.

[0116] Optionally, combined Figure 6 As shown, a surface of the first cover plate 41 facing the air duct groove 231 is provided with air guiding ribs 413 , and the air guiding ribs 413 extend along the bottom of the first cover plate 41 toward the position of the first air outlet 411 .

[0117] In this way, the flow direction of the cold air is guided by the air guide ribs 413 so that the cold air can smoothly reach the first air outlet 411 along a predetermined path.

[0118] Optionally, combined Figure 7 As shown, the top of the first cover plate 41 is provided with a second air outlet 412 for discharging air toward the front and / or backward; and / or, a side air supply port is opened on the side wall of the volute of the fan 30, and a third air outlet 421 is provided at a position of the second cover plate 42 corresponding to the side air supply port, and the third air outlet 421 is connected to the side air supply port, and the third air outlet 421 discharges air to the left or right.

[0119] Cold air is heavy and easy to sink. The second air outlet 412 is provided at the top of the first cover plate 41. In this way, the items in the refrigeration space are cooled during the sinking of the cold air, thereby improving the refrigeration efficiency. The fan 30 is generally provided at the bottom of the refrigeration space. In this way, the bottom of the refrigeration space can be directly cooled through the third air outlet 421, thereby preventing excessive accumulation of items at the bottom, which affects the sinking speed of the cold air and thus affects the refrigeration efficiency at the bottom.

[0120] It can be understood that in order to improve the cooling speed and cooling uniformity, the first air outlet 411, the second air outlet 412 and the third air outlet 421 can exist at the same time.

[0121] Optionally, combined Figure 8 and Fig. 9 As shown, the refrigerator 10 further includes an extended air duct 70, which is disposed on the front wall 28 and / or the rear wall 29 of the inner container 20 and extends along the length direction of the inner container 20. The extended air duct 70 is connected to at least one of the first air outlet 411 and the third air outlet 421, and the extended air duct 70 is provided with a fourth air outlet 71.

[0122] In this way, by extending the air duct 70 and the fourth air outlet 71, the uniformity of the temperature in the storage cavity can be further improved, and the cooling speed can be increased.

[0123] Optionally, the fourth air outlet 71 is in a square or circular shape. When the fourth air outlet 71 is in a circular shape, the extended air duct 70 includes an air outlet panel, and the fourth air outlets 71 are distributed on the air outlet panel in a rectangular array.

[0124] When the fourth air outlet 71 is in a square shape, the extended air ducts 70 are arranged at intervals in the vertical direction, and the extended air ducts 70 can be arranged on both sides of the air duct groove 231, or only on one side of the air duct groove 231. One extended air duct 70 is arranged corresponding to one first air outlet 411 or one third air outlet 421.

[0125] When the fourth air outlet 71 is circular in shape, the extended air duct 70 is an air outlet panel. The air outlet panel completely covers the front wall 28 and / or the rear wall 29 of the liner 20, and the fourth air outlet 71 is distributed on the air outlet panel in a rectangular array.

[0126] Optionally, the air outlet direction of the fourth air outlet 71 is away from the extended air duct 70 , and extends along the width direction of the inner liner 20 , or extends along the height direction of the inner liner 20 .

[0127] For example, the rear wall 29 of the inner liner 20 is provided with a fourth air outlet 71. The air outlet direction of the fourth air outlet 71 can be forward, upward or downward.

[0128] Furthermore, a shutter structure may be provided at the fourth air outlet 71 , and the air outlet direction of the fourth air outlet 71 may be controlled by controlling the swinging direction of the shutter structure.

[0129] Optionally, combined Fig.10 As shown, the refrigerator 10 also includes a side air duct 80, which is arranged on the left side wall and / or the right side wall of the inner liner 20 and extends along the width direction of the inner liner 20. The side air duct 80 is connected to the extended air duct 70, and the side air duct 80 is provided with a fifth air outlet 81.

[0130] In this way, air ducts and air outlets are arranged on the front, rear, left and right inner wall surfaces of the inner tank 20, the distribution of cold is more uniform, the temperature difference in the storage cavity is smaller, the uniformity is better, and the refrigeration effect of the refrigerator 10 is greatly improved.

[0131] Optionally, the air outlet direction of the fifth air outlet 81 is away from the side air duct 80 , and extends along the length direction of the inner liner 20 , or extends along the height direction of the inner liner 20 .

[0132] For example, taking the rear wall 29 of the inner liner 20 as an example, the fifth air outlet 81 can be provided with an air outlet direction forward, upward or downward.

[0133] Furthermore, a shutter structure may be provided at the fifth air outlet 81 , and the air outlet direction of the fifth air outlet 81 may be controlled by controlling the swinging direction of the shutter structure.

[0134] Optionally, the refrigerator 10 further includes an evaporator cover 51 and a refrigeration structure. The evaporator cover 51 is provided on the upper surface of the bottom wall of the liner 20, and the refrigeration space is divided into a storage cavity and an evaporator compartment 50. The evaporator compartment 50 is provided with a return air port 511, and the return air port 511 includes at least one of an upper return air port 512, a lower return air port 513, and a side return air port 514. The refrigeration structure is provided in the evaporator compartment 50, and is configured to cool the air in the storage cavity, and drive the air flow to discharge air from the first air outlet 411 and return air from the return air port 511, so as to realize the circulation of air between the storage cavity and the evaporator compartment 50.

[0135] In this way, when multiple return air outlets 511 are respectively arranged at different positions of the evaporator compartment 50, the return air speed is faster, which can further speed up the refrigeration speed of the freezer 10, shorten the time required for the temperature in the storage cavity to reach the predetermined refrigeration temperature, and save energy consumption.

[0136] Optionally, the refrigerator 10 further includes a return air duct, which is disposed on the front wall 28 and / or the rear wall 29 of the inner container 20 , and the return air duct is connected to the return air port 511 .

[0137] For example, an air duct groove 231 is set on the rear wall 29 of the inner liner 20, and a return air duct is set on the front wall 28 of the inner liner 20. In this way, the fan 30 transports cold air into the air duct groove 231, and discharges air into the storage cavity through the air outlet 511, while the hot air in the storage cavity flows into the return air duct, enters the evaporator compartment 50 through the return air outlet 511 connected to the return air duct, and exchanges heat with the evaporator 52, thereby realizing the circulation of air between the storage cavity and the evaporator compartment 50.

[0138] Optionally, combined Fig.13 As shown, the refrigeration structure includes an evaporator 52, and the evaporator compartment 50 also includes a support plate 53. The support plate 53 is arranged in the evaporator cover plate 51, and is used to support the evaporator 52, and the lower return air port 513 is arranged on the support plate 53. Among them, the support plate 53 divides the evaporator compartment 50 into two layers of space, and the evaporator 52 is located in the upper space. The side return air port 514 is arranged on the evaporator cover plate 51, and the side return air port 514 is connected to the lower space. The air in the storage cavity enters the lower space through the side return air port 514, and then enters the upper space through the lower return air port 513, and flows out after heat exchange with the evaporator 52.

[0139] In this way, the air in the storage cavity enters the lower space through the side return air port 514 , and then enters the upper space through the lower return air port 513 , and flows out after exchanging heat with the evaporator 52 , thereby realizing air return at the bottom of the evaporator 52 .

[0140] Optionally, combined Fig.11 and Fig.12 As shown, the upper return air outlet 512 and the side return air outlet 514 are both arranged on the evaporator cover plate 51 .

[0141] In this way, the refrigerator 10 can also achieve upper return air and side return air through the evaporator cover 51 .

[0142] It is understandable that the first air outlet 411, the second air outlet 412, the third air outlet 421, the extended air duct 70, the side air duct 80 and the upper return air outlet 512, the lower return air outlet 513, and the side return air outlet 514 can be randomly combined to form a variety of air supply and return schemes.

[0143] Optionally, the inner liner 20 is an integrally molded adsorption inner liner 20, and one or more of the air duct groove 231, the evaporator compartment 50, the extended air duct 70 and the side air duct 80 are adsorption molded; or, the inner liner 20 is a spliced ​​inner liner 20, and one or more of the air duct groove 231, the evaporator compartment 50, the extended air duct 70 and the side air duct 80 are spliced ​​from plastic parts.

[0144] For example, when the liner 20 is an adsorption liner 20, the air duct groove 231 can be adsorbed or formed by splicing plastic parts. When the liner 20 is a spliced ​​liner 20, the extended air duct 70 can be formed by splicing plastic parts or adsorbed.

[0145] Take the splicing liner 20 as an example, combined with Figures 1 to 5 As shown, the embodiment of the present disclosure provides an inner liner 20 for a refrigerator 10, including a first enclosure 21, a second enclosure 22 and a splicing plate 23. The first enclosure 21 is vertically arranged and enclosed in a U shape, forming a first opening 211 on the right side. The second enclosure 22 is vertically arranged and enclosed in a U shape, opposite to the first enclosure 21, forming a second opening 221 on the left side, and the second opening 221 is opposite to the first opening 211. The splicing plate 23 is arranged between the first opening 211 and the second opening 221, and connects the side of the first opening 211 and the side of the second opening 221, and the splicing plate 23 is provided with a pre-buried air duct groove 231.

[0146] The inner liner 20 for the refrigerator 10 provided by the embodiment of the present disclosure is used. The splicing plate 23 is spliced ​​with the first enclosure 21 and the second enclosure 22 to form the inner liner 20. The air duct groove 231 is pre-set on the splicing plate 23. In this way, the process difficulty of forming the air duct groove 231 is reduced, and the defective rate of the product is greatly reduced. In addition, the inner liner 20 is divided into three common parts, namely the splicing plate 23, the first enclosure 21 and the second enclosure 22, which has good versatility and can form inner liner 20 of different specifications according to user needs.

[0147] Optionally, combined Figure 2 and Figure 3 As shown, the sides of the splicing plate 23 facing the first opening 211 and the second opening 221 are provided with grooves 232, and the sides of the first opening 211 and the second opening 221 are provided with matching plug-in parts 24, which are respectively inserted into the corresponding grooves 232 to realize the connection between the first enclosure 21, the second enclosure 22 and the splicing plate 23.

[0148] In this way, the connection between the first enclosure panel 21, the second enclosure panel 22 and the splicing panel 23 is achieved through the plug-in fit between the plug-in portion 24 and the groove 232.

[0149] Optionally, the first opening 211 includes a first side 2111 and a second side 2112 extending vertically, the second opening 221 includes a third side 2211 and a fourth side 2212 extending vertically, the first side 2111 is arranged opposite to the third side 2211, and the second side 2112 is arranged opposite to the fourth side 2212. The splicing plate 23 includes a first side wall 233 and a second side wall 234. The first side wall 233 connects the first side 2111 and the third side 2211, and the second side wall 234 connects the second side 2112 and the fourth side 2212. The air duct groove 231 is arranged on the first side wall 233 and / or the second side wall 234.

[0150] The first enclosure 21 is vertically arranged and surrounded in a U shape, and a first opening 211 is formed on the right side. Then the first opening 211 is U-shaped, and the first side 2111 and the second side 2112 extend vertically, that is, the first side 2111 and the second side 2112 are arranged relative to each other in the front-to-back direction. Similarly, the third side 2211 and the fourth side 2212 are also arranged relative to each other in the front-to-back direction. The first side wall 233 connects the first side 2111 and the third side 2211, and the second side wall 234 connects the second side 2112 and the fourth side 2212. Then, it can be obtained that the first side wall 233 and the second side wall 234 are arranged relative to each other in the front-to-back direction, and are located in the middle area of ​​the front wall 28 and / or the rear wall 29 of the inner liner 20, so that the air duct groove 231 is located in the middle area of ​​the front wall 28 and / or the rear wall 29 of the inner liner 20. Specifically, the air duct groove 231 may be disposed only on the first side wall 233 or the second side wall 234 , or may be disposed on both the first side wall 233 and the second side wall 234 .

[0151] Optionally, the air duct groove 231 is extended along the height direction of the inner container 20 and is arranged on the first side wall 233 and / or the second side wall 234 .

[0152] In this way, a vertically upward air duct groove 231 can be obtained. In the case where the splicing plate 23 is a plastic part, the air duct groove 231 is pre-buried and formed in advance, and does not need to be adsorbed later, which reduces the process difficulty of forming the air duct groove 231 and saves costs.

[0153] Optionally, combined Figure 4 As shown, the splicing plate 23 further includes a bottom side wall 235 , which is extended along the width direction of the inner container 20 and connects the bottom of the first side wall 233 and the bottom of the second side wall 234 .

[0154] In this way, the first side wall 233 , the second side wall 234 and the bottom side wall 235 form a thick U-shaped splicing plate 23 , the left side of the U-shaped splicing plate 23 is connected to the first enclosure 21 , and the right side of the U-shaped splicing plate 23 is connected to the second enclosure 22 .

[0155] Optionally, the liner 20 further includes a first bottom wall 25 disposed at the bottom of the first enclosure 21 and a second bottom wall 26 disposed at the bottom of the second enclosure 22, wherein the second bottom wall 26 is higher than the first bottom wall 25.
