[0029] An embodiment of the present disclosure provides a refrigeration appliance including a cabinet 400, as shown in Figures 1 to 41, where the cabinet 400 includes a box liner.

[0030] The refrigeration appliance may be a number of types of appliances, such as a refrigerator, a freezer, a display case, a sales case, or a liquor cabinet, and the refrigeration appliance may be used for refrigeration or freezing.

[0031] In the following embodiments, the directions of front, back, left, right, up and down correspond one-to-one to the directions of the refrigeration equipment.

[0032] An embodiment of the present disclosure provides a box liner, which includes a box liner body 300 and an air duct component 200, and the space within the box liner body 300 is divided into a first compartment 410 and a second compartment 420 that are independent of each other by the air duct component 200.

[0033] Air passage component 200 can serve to separate the compartments and also serve to circulate air. In order to ensure the independence of first compartment 410 and second compartment 420, it is necessary to ensure that the attachment points of air passage component 200 and box liner body 300 are sealed to prevent gases from mixing between first compartment 410 and second compartment 420.

[0034] An embodiment of the present disclosure provides an air duct component 200, which may divide the entire space within the box liner body 300 into two parts, a first compartment 410 and a second compartment 420, or the air duct component 200 may partition a partial space within the box liner body 300 into two parts, a first compartment 410 and a second compartment 420.

[0035] Air-channel component 200 blows air to first compartment 410 and second compartment 420 independently, and the functions of first compartment 410 and second compartment 420 may be the same or different. If first compartment 410 and second compartment 420 have different functions, i.e., if the ambient temperatures within first compartment 410 and second compartment 420 are different, first compartment 410 may be a refrigeration compartment and second compartment 420 may be a freezer compartment, and air-channel component 200 blows air to the refrigeration compartment less frequently than to the freezer compartment. If first compartment 410 and second compartment 420 have the same function, for example, if both compartments are refrigeration compartments, the ambient temperatures of the two refrigeration compartments may be the same or different. In this case, the frequencies at which air-channel component 200 blows air to the two refrigeration compartments may be the same or different, and can be set as needed. Of course, the functions of the compartments separated by the air passage component 200 are not limited to refrigeration and freezing, but may be variable temperature compartments or compartments with other functions, and can be specifically set as needed.

[0036] When the cabinet 400 is connected to the door body and the door body is in a position that seals the cabinet 400, the first compartment 410 and the second compartment 420 are two sealed and independent spaces, and when the door body is in a position that opens the cabinet 400, items can be taken in and out of at least one of the first compartment 410 and the second compartment 420.

[0037] Here, the number of air passage components 200 installed in the refrigeration equipment can be set as needed.

[0038] As will be understood, as shown in Figures 2 to 3, 10, 11, and 17 to 20, the air passage component 200 includes a partition plate member 210, an air passage member 220, an evaporator 230, and a drainage plate 100, and the partition plate member 210 is located above the air passage member 220, and the partition plate member 210 and the air passage member 220 form a first cavity 282, an intake port suitable for communicating with the first cavity 282, and an exhaust port suitable for communicating with the first cavity 282, and the evaporator 230 and the drainage plate 100 are provided within the first cavity 282, and the drainage plate 100 is located below the evaporator 230. The partition plate member 210 and the air passage member 220 jointly define an air intake port, a first cavity 282, and an air exhaust port that are in communication with each other so that air that enters the air passage component 200 exchanges heat before being discharged.

[0039] 1 and 2, the partition plate member 210 is connected to the box liner main body 300, and the connection between the partition plate member 210 and the box liner main body 300 is sealed so as to divide the space within the box liner main body 300 into a first compartment 410 and a second compartment 420 that are independent of each other. A first cavity 282 between the partition plate member 210 and the air passage member 220 is used to mount components such as an evaporator 230, a drain plate 100, a heating structure for defrosting, etc., to meet the demand for heat exchange between the first compartment 410 and the second compartment 420.

[0040] The air intake port of the air duct component 200 is divided into a first air intake port 201 and a second air intake port 202, and the air exhaust port of the air duct component 200 is divided into a first air exhaust port 203 and a second air exhaust port 204, the first air intake port 201, the first cavity 282, the first air exhaust port 203 and the first compartment 410 are connected to form a first circulation path, the second air intake port 202, the first cavity 282, the second air exhaust port 204 and the second compartment 420 are connected to form a second circulation path, and the first circulation path is connected to at least one of the second circulation paths so as to blow air to the first compartment 410 and the second compartment 420. The number and positions of the first intake port 201, the second intake port 202, the first exhaust port 203, and the second exhaust port 204 are not limited.

[0041] As shown in Figures 1 and 2, the first compartment 410 is located above the air duct component 200, and the first compartment 410 is provided as a refrigeration compartment, and the second compartment 420 is located below the air duct component 200, and the second compartment 420 is provided as a freezer compartment; that is, the first compartment 410 is located above the second compartment 420, and the air duct component 200 is provided with a first exhaust port 203 facing upward and a second exhaust port 204 facing downward, and the first exhaust port 203 is provided with a first damper 250 for adjusting opening and closing, and the second exhaust port 204 is provided with a second damper for adjusting opening and closing. A first air intake 201 and a second air intake 202 are provided near the front end of the air duct component 200, the first air intake 201 being connected to the return air duct of the refrigeration compartment and provided on both the left and right sides of the air duct component 200, and the second air intake 202 being connected to the freezer compartment and provided on the front or bottom side of the air duct component 200.

[0042] In addition, the first air intake 201 and the second air intake 202 are near the same end of the air duct component 200, the first air exhaust 203 and the second air exhaust 204 are also near the same end of the air duct component 200, and the air intake and exhaust are generally located at opposite ends, with the air intake being near the front end and the exhaust being near the rear end as described above, but are not limited to the above positions, and both air intakes may be near the left end or the right end, and the positions of the air intake and exhaust are flexible and can be selected as needed.

[0043] In some cases, the first air intake 201 is located on a first side of the first cavity 282, and the second air intake 202 is located on a second side of the first cavity 282, and the first side and the second side are adjacent, i.e., the first air intake 201 and the second air intake 202 are located on different sides of the air duct component 200. In this case, the intake air of the first air intake 201 and the intake air of the second air intake 202 meet within the first cavity 282, and the first air intake 201 and the second air intake 202 have different intake temperatures (i.e., the first compartment 410 and the second compartment 420 have different environmental temperatures), and the meeting point of the intake air through the first air intake 201 and the intake air through the second air intake 202 is prone to frost due to heat exchange through contact. The fact that the first intake port 201 and the second intake port 202 are located on different sides of the air-duct component 200 may be understood as the first intake port 201 and the second intake port 202 forming an included angle.

[0044] As shown in FIG. 6, the first side is at least one of the left side and the right side, and the second side is the front side.

[0045] 1 to 16 and 20 to 25, embodiments of the drainage plate 100 are provided, and the structure of the drainage plate 100 will be described using an example in which the drainage plate 100 is attached to the above-mentioned air passage component 200. However, the drainage plate 100 is not limited to being attached to the above-mentioned air passage component 200, and the drainage plate 100 described below may be attached to other structures suitable for attaching the drainage plate 100 in the following embodiments.

[0046] An embodiment of the present disclosure provides a drainage plate 100, as shown in Figures 1 to 7, which is configured with a water-guiding portion that is recessed downward relative to the ceiling surface of the drainage plate 100, and the water-guiding portion extends to the edges of the drainage plate 100 toward both sides of a predetermined surface so that the edges of the drainage plate 100 form openings 170, and the openings 170 face toward the side where the first air intake port 201 is located so that some of the air intake by the first air intake port 201 passes through the openings 170 and flows into the first cavity 282 along the extension direction of the water-guiding portion.

[0047] The function of the first air intake 201 here is not limited, and it may communicate with the refrigerated compartment with a water guide to guide refrigerated air, or it may communicate with the freezer compartment with a water guide to guide refrigerated air. By providing a water guide, the drain plate can be designed in an inverted V-shape, allowing some refrigerated return air to enter the evaporator 230 through the V-shaped structure, thereby solving the problem of return air condensation in the refrigerator, reducing contact between the refrigerated return air and the refrigerated return air, reducing condensation caused by condensation and mixing with the refrigerated return air, distributing frost more evenly within the evaporator, and reducing blockage of the refrigerated return air due to frost.

[0048] A portion of the air taken in by the first air intake port 201 passes through the opening 170 and is introduced into the first cavity 282 along the extension direction of the water guide section, diverting a portion of the air taken in by the first air intake port 201 and reducing the amount of air that merges with the air taken in by the second air intake port 202, and further reducing the frost that condenses when the air taken in by the first air intake port 201 comes into contact with the air taken in by the second air intake port 202, thereby extending the interval between two defrosting operations, reducing the number of defrosting operations, reducing the power consumption required for defrosting, and reducing the power consumption of the refrigeration equipment.

[0049] As the water guide section is recessed downward relative to the ceiling surface of the drainage plate 100, a groove is formed in the drainage plate 100, and some of the air taken in by the first air intake port 201 flows along the groove into the first cavity 282, with the water guide section playing a role in guiding the wind within.

[0050] Here, the predetermined surface and the extending direction of the water guide portion form an included angle, and the predetermined surface extends in the direction from the air intake port to the exhaust port, and for example, if the air intake port is located at the front end of air channel component 200 and the exhaust port is located at the rear end of air channel component 200, the predetermined surface extends from front to rear. Here, the extension tendency of the predetermined surface only needs to be from front to rear, and the predetermined surface may extend at an angle, and the position of the predetermined surface can be selected as needed.

[0051] In some cases, the specified plane may be a symmetrical plane of the drainage plate 100, and the water guide portions may be symmetrically arranged on both sides of the specified plane, thereby making the drainage plate 100 have a symmetrical structure and improving the structural stability of the drainage plate 100.

[0052] Of course, the predetermined plane is not limited to the plane of symmetry, and the opening 170 may be provided on one or both sides of the drainage plate 100. When the opening 170 is provided on one side of the drainage plate 100, the predetermined plane may be one side of the drainage plate 100, which side is located opposite the first air intake port 201, and when the opening 170 is provided on both sides of the drainage plate 100, the predetermined plane may be any plane extending from front to rear.

[0053] The openings 170 of the drainage plate 100 can serve as a guide for a portion of the air drawn in by the first air inlet 201, and the openings 170 of the drainage plate 100 can also serve as a drain.

[0054] When the opening 170 of the drainage plate 100 serves to divert a portion of the intake air, the depth to which the water guide portion is recessed relative to the ceiling surface of the drainage plate 100 is not limited.

[0055] In some cases, the recessed depth of the water guide section gradually increases toward the opening 170, and the water guide section with this structure may be called the second water guide section 130. That is, the second water guide section 130 has a relatively large depth at one end toward the opening 170, which contributes to guiding the airflow therein. When the evaporator 230 is disposed above the drainage plate 100, the depth of the second water guide section 130 gradually increases, and the gap between the evaporator 230 and the drainage plate 100 also increases, which can appropriately expand the airflow space and further contribute to draining the defrost water received by the drainage plate 100 through the opening 170.

[0056] Here, the depth of the second water guide portion 130 gradually increases toward one end of the opening 170, and may increase continuously or in steps.

[0057] As can be seen, the bottom of the second water guide section 130 is inclined along a first predetermined direction toward the opening 170, and the first predetermined direction forms a first predetermined angle with the ceiling surface of the drainage plate 100. In other words, the bottom surface of the second water guide section 130 is a slope extending downward along the first predetermined direction, which contributes to the flow of wind into the first cavity 282 and also facilitates drainage.

[0058] The first predetermined direction is a direction that forms a first predetermined angle with the ceiling surface and is inclined diagonally downward relative to the opening 170 along the predetermined surface, and the magnitude of the first predetermined angle can be selected as needed.

[0059] In order to reduce the height size of the drainage plate 100, the first predetermined included angle may be an included angle of 7° or less, so that the drainage effect and the wind guidance effect can both be met, and the height size of the air duct component 200 can be reduced, and the height space occupied by the air duct component 200 in the cabinet 400 can be reduced, which contributes to increasing the compartment space in the cabinet 400 and helps to provide a large-capacity refrigeration equipment.

[0060] In some cases, the first predetermined included angle is set as 3°, which can meet the drainage demand of the drainage plate 100 and further make the height of the drainage plate 100 small enough to achieve small-angle drainage. Of course, the first predetermined included angle can also be set as 1°, 2°, 4°, 5°, 6°, or 7°.

[0061] Of course, the recessed depth of the second water guide portion does not have to change (not shown), and the recessed depth of the second water guide portion remains consistent, so that it can also serve as a wind guide and drainage portion.

[0062] As will be understood, the water conducting section includes a flow conducting surface provided along the extension direction of the water conducting section, and the flow conducting surface approaches the opposing side surface in the direction from the ceiling surface toward the bottom surface of the drainage plate 100. In other words, the second water conducting section 130 is provided with a third flow conducting surface 131 along its extension direction, and in the direction from the ceiling surface toward the bottom surface of the drainage plate 100, the third flow conducting surface 131 approaches the opposing side surface, and the third flow conducting surface 131 is an inclined surface that slopes toward the opposing side.

[0063] The defrost water received by the ceiling surface of the drainage plate 100 and the third flow guide surface 131 can fall to the bottom of the water guide section along the flow guide direction of the third flow guide surface 131, thereby collecting the defrost water within the water guide section and facilitating the discharge of water within the water guide section.

[0064] The side surface opposite the third flow guide surface 131 may be an upright surface or a flow guide surface, and can be specifically selected as needed. As shown in Figures 5 and 6, the two opposing side surfaces of the second water guide section 130 are both third flow guide surfaces 131.

[0065] As shown in Figures 5 to 7, a plurality of second water guide sections 130 are provided on each side of a specified surface of the drainage plate 100, and the plurality of second water guide sections 130 are arranged in parallel, and a plurality of openings 170 are formed on both sides of the drainage plate 100 so that some of the air intake by the first air intake port 201 can enter the first cavity 282 along the plurality of openings 170.

[0066] At a predetermined height, the width of the second water guide portion 130 gradually decreases in the direction of the opening 170 so that the water received in the second water guide portion 130 is gathered in the direction of the opening 170 .

[0067] 1 to 7 and the above description, the drainage plate 100 having the second water guide portion 130 does not necessarily have to be provided with the drainage portion 110.

[0068] As shown in Figures 1 to 16 and Figures 20 to 25, an embodiment of the present disclosure provides another drainage plate 100, which is configured with a water-guiding portion that is recessed relative to the ceiling surface of the drainage plate 100, and the extension direction of the water-guiding portion and the air supply direction above the drainage plate 100 form a fourth included angle.

[0069] When the drainage plate 100 and the evaporator 230 are both installed in the first cavity 282 of the air-channel component 200, air flows from the air intake port of the air-channel component 200 into the first cavity 282 and flows toward the air exhaust port. The air in the first cavity 282 flows in the space between the drainage plate 100 and the evaporator 230 and in the space inside the evaporator 230. When the air flows between the drainage plate 100 and the evaporator 230, the water guide portion and the air blowing direction form a fourth included angle, which prevents the air from flowing directly from the water guide portion to the air exhaust port. This extends the time the air stays in the first cavity 282, allows the air to fully come into contact with the evaporator 230 and exchange heat. After heat exchange, the air is then discharged through the air exhaust port, contributing to improved heat exchange efficiency.

[0070] Here, the air delivery direction is the direction from the air intake port to the air exhaust port. In some cases, there is one air intake port and one air exhaust port, and they correspond one-to-one to form one air delivery direction. In some cases, at least one of the air intake port and the air exhaust port may be provided in multiple locations, forming multiple air delivery directions. The extension direction of the water guide portion and at least one of the air delivery directions form an included angle, thereby ensuring the heat exchange efficiency of the air in one direction. Of course, when the extension direction of the water guide portion and all of the air delivery directions form an included angle, it is possible to ensure that the air in each of the multiple flow paths can effectively exchange heat, thereby ensuring the heat exchange efficiency. Here, the air intake port is generally provided at a front end of the air duct component 200, and the air exhaust port is generally provided at a rear end of the air duct component 200, and the air delivery direction may be from front to rear.

[0071] The air intake is divided into a first air intake 201 and a second air intake 202, the second air intake 202 is provided in front of the air duct component 200, the exhaust port is provided in the rear of the air duct component 200, the communication path between the second air intake 202 and the exhaust port forms a first air supply direction, and when the second air intake 202 corresponds to a position near the bottom of the evaporator 230, the air flows from bottom to top and from front to rear.

[0072] In the drainage plate 100 according to this embodiment, the extension direction of the water guide portion and the first air supply direction form an included angle, i.e., the extension direction of the water guide portion and the front-to-rear direction form an included angle. The first air intake port 201 may be provided on at least one of the left and right sides of the air passage component 200, and the communication path between the first air intake port 201 and the exhaust port forms a second air supply direction, and also forms an included angle with the extension direction of the water guide portion and the second air supply direction. Both the included angle between the extension direction of the water guide portion and the first air supply direction and the included angle between the extension direction of the water guide portion and the second air supply direction may be understood as a fourth included angle, but the specific angle may be the same or different.

[0073] The extension direction of the water conducting section may be a straight path or a curved path. If the extension path of the water conducting section is a straight path, the path from one end of the water conducting section away from the drainage section 110 to the other end of the water conducting section that communicates with the drainage section 110 is the extension path. If the extension path of the water conducting section is a curved path, the curved water conducting section may have headers that communicate with multiple drainage sections 110. The curved path may be a broken line path formed by connecting multiple straight path segments, or the curved path may be a curve with one or more radii of curvature. The shape of the curved path can be set as needed. The extension direction of one water conducting section may form one or more included angles with the air supply direction. That is, the fourth included angle may be one or more angle values, and can be specifically set as needed.

[0074] As shown in Figures 10 to 25, an embodiment of the present disclosure provides another drainage plate 100, which is configured to have a drainage section 110 and a water guide section, and the drainage section 110 is configured to have an outlet 114, and the drainage section 110 is recessed relative to the ceiling surface of the drainage plate 100, and the water guide section is connected to the drainage section 110, and the water guide section is recessed relative to the ceiling surface of the drainage plate 100, and the extension direction of the water guide section and the air supply direction above the drainage plate 100 form a fifth included angle θ1.

[0075] In use, the drain plate 100 is located below the evaporator 230 and is used to collect defrost water generated when frost on the surface of the evaporator 230 is exposed to heat. Some of the water falls into the water conducting section and is introduced into the drain section 110 along the extension direction of the water conducting section. There are generally multiple water conducting sections, and the water received by each water conducting section is collected in the drain section 110 and discharged through the outlet 114 of the drain section 110. The other part of the water falls directly into the drain section 110 and is discharged through the drain section 110.

[0076] The difference between the fifth included angle and the fourth included angle is that in a drainage plate where both a water conducting section and a drainage section are provided, the angle between the extension direction of the water conducting section and the air supply direction is the fifth included angle, while in a drainage plate where only a water conducting section is provided, the angle between the extension direction of the water conducting section and the air supply direction is the fourth included angle. The angle values ​​of the fifth included angle and the fourth included angle can be selected as needed and are not limited here.

[0077] In Figure 23, the solid arrow above the drainage plate 100 indicates the extension direction of the water guide section, the dashed arrow indicates the air supply direction, and the fifth included angle θ1 is shown, with the fifth included angle being 90° in the figure. The water guide section and the drainage section 110 are both recessed based on the ceiling surface of the drainage plate 100, and the ceiling surface may be flat or curved, and may be a surface defined by multiple lines or multiple surfaces. Correspondingly, the bottom of the water guide section and the bottom of the drainage section 110 form the bottom surface of the drainage plate 100, and the bottom surface may be flat or curved, and may be a surface defined by multiple lines or multiple surfaces. The top surface of the drainage plate 100 is all surfaces of the drainage plate 100 facing upward, with the ceiling surface being part of the top surface, and the bottom surface of the drainage plate 100 is all surfaces of the drainage plate 100 facing downward, with the bottom surface being part of the bottom surface.

[0078] According to the drainage plate 100 of this embodiment, the water guide section can cooperate with the drainage section 110 to discharge the received water, thereby solving the problem of drainage within the air duct component 200. Furthermore, by arranging the water guide section so that its extension direction and the air supply direction of the air duct component 200 form an included angle, the heat exchange efficiency can be improved and the time that the air stays within the air duct component 200, i.e., the heat exchange time, can be extended to meet the refrigeration demand of the refrigeration equipment, and the structure of the drainage plate 100 is simple.

[0079] Regarding the structure of the drainage plate 100 according to the embodiment of the present disclosure, the depth of the water guide section recessed downward relative to the ceiling surface of the drainage plate 100 is constant, and the drainage plate 100 is configured with a drainage section 110 recessed relative to the ceiling surface of the drainage plate 100, which may also be called a third water guide section 140, and as shown in Figures 11 to 13, the drainage section 110 is configured with an outlet 114, and the third water guide section 140 is connected to the drainage section 110, and the defrost water received by the third water guide section 140 may be discharged from the opening 170 at the end of the drainage plate 100 or from the outlet 114 of the drainage section 110, thereby realizing multi-directional drainage, with a simple structure and good drainage effect.

[0080] In this case, the evaporator 230 and the drain plate 100 can be arranged horizontally, allowing for complete discharge of defrost water and further reducing the height of the air duct component 200. If the evaporator 230 and the drain plate 100 are both installed obliquely downward to drain water, the downward inclination angle of the evaporator 230 and the drain plate 100 (the downward inclination angle of the evaporator 230 and the drain plate 100 may be 7° or less) can be reduced, further reducing the size of the air duct component 200 in the height direction and serving to expand the capacity inside the refrigeration equipment.

[0081] The outlet 114 and exhaust port of the drainage section 110 are located on the same side of the first cavity 282, and the drainage section and the exhaust section are located on the same side of the first cavity 282, which makes it easy to integrate the drainage structure and the exhaust structure.

[0082] A fan 270 is provided within the air passage component 200, and when the fan 270 and the exhaust port are located on the same side, that is, when the outlet 114, the exhaust port, and the fan 270 are all located on the same side, the defrost water of the fan 270 can be discharged together with the defrost water of the drain plate 100.

[0083] Along the extension direction of the drainage section 110, multiple third water guide sections 140 are arranged in parallel on both sides of the drainage section 110, and the multiple third water guide sections 140 are distributed below the evaporator 230, which makes it easy to receive defrost water at multiple positions below the evaporator 230 and contributes to rapid drainage.

[0084] A plurality of drainage sections 110 may be provided, and the plurality of drainage sections 110 may be parallel to each other or may form an included angle. If the area of ​​the drainage plate 100 remains unchanged, the greater the number of drainage sections 110, the shorter the length of the third water guide section 140, which contributes to the water received by the third water guide section 140 collecting within the drainage section 110 and facilitates shortening the drainage time of defrost water. When a plurality of drainage sections 110 are provided, the third water guide section 140 near the edge of the drainage plate has an opening, and the other third water guide sections 140 communicate with the drainage section 110.

[0085] As can be seen, the recessed depth of the drainage portion 110 gradually increases in the direction of the outlet 114, which facilitates the water in the drainage portion 110 to flow to the outlet 114 under the action of gravity.

[0086] As can be seen, the bottom of the drainage part 110 is inclined along the second direction, and the second direction forms a seventh included angle θ3 with the ceiling surface of the drainage plate 100. That is, the bottom of the drainage part 110 is inclined, and the water in the drainage part 110 is collected and discharged to the outlet 114 along the inclined path (second direction), which improves the drainage effect, avoids the problem of localized water accumulation, and allows the water to flow smoothly.

[0087] The fact that the ceiling surface of the drain plate 100 is horizontal may be understood as the seventh included angle θ3 formed between the second direction and the horizontal plane. The drain portion 110 is gradually recessed downward along the ceiling surface of the drain plate 100 toward the position of the outlet 114. In this case, the seventh included angle θ3 is the angle between the bottom of the drain portion 110 and the horizontal plane, and the second direction is a diagonally downward direction.

[0088] Here, the bottom of the drainage section 110 may be an inclined line or a slope, and in some cases, the bottom of the drainage section 110 is a slope, and the slope may be a flat or curved surface, which can be specifically selected as needed.

[0089] In some cases, the bottom of the drainage section 110 may not form a continuous slope or incline, but may still meet drainage needs, for example, if it is stepped.

[0090] As can be understood, the seventh included angle θ3 may be 7° or less, and a small angle of the seventh included angle θ3 contributes to reducing the distance from the ceiling surface to the bottom surface of the drainage plate 100, thereby realizing small-angle drainage, and further reduces the vertical size of the air duct component 200, reducing the space occupied by the air duct component 200, contributing to improving the storage space of the refrigeration equipment, and providing a large-capacity refrigeration equipment.

[0091] In addition, the seventh included angle θ3 may be greater than 7°. Since the area of ​​the drainage plate 100 occupied by the drainage section 110 is relatively small, the angle at which the drainage section 110 slopes downward is somewhat large, and the impact on the overall volume of the drainage plate 100 is not significant, the angle of the seventh included angle θ3 is not strictly limited.

[0092] 12, the recessed depth of the drainage portion 110 is constant, in which case the drainage portion may be called a third drainage portion 115, and the drainage plate 100 is inclined toward the outlet 114 to facilitate drainage. For example, the outlet 114 is located at the rear end of the air passage component 200, and the drainage plate 100 is inclined diagonally downward from front to rear so that the water in the drainage portion 110 flows backward and is discharged.

[0093] 11 and 12, the third water guide section 140 includes a fourth flow guide surface 141 provided along the extension direction of the third water guide section 140, and the fourth flow guide surface 141 approaches the opposing side surface in the direction from the ceiling surface to the bottom surface of the drainage plate 100. The fourth flow guide surface 141 guides defrost water received by the ceiling surface of the drainage plate 100 and the fourth flow guide surface 141 to the bottom of the third water guide section 140 so that the water in the third water guide section 140 is discharged.

[0094] In the direction from the bottom surface of the drainage plate 100 toward the ceiling surface, the fourth flow guide surface 141 is inclined toward the outlet 114. When the drainage plate 100 is inclined toward the outlet 114 and the amount of water collected in the third water guide section 140 is relatively large, the fourth flow guide surface 141 can guide the water backward, so that some of the water flow is discharged from the rear.

[0095] In an embodiment of the present disclosure, as shown in Figures 20 to 25, the depth of the recess of the water conducting section gradually increases in the direction of the drainage section 110, and in this case, the water conducting section may be referred to as the first water conducting section 120. The depth of the first water conducting section 120 gradually increases in the direction of the drainage section 110 so that water flows into the drainage section 110 by the action of gravity and is discharged from the outlet 114 of the drainage section 110.

[0096] As can be seen, the bottom of the first water guide section 120 is inclined along the first direction toward the drainage section 110, and the first direction forms a sixth included angle θ2 with the ceiling surface of the drainage plate 100. That is, the bottom of the first water guide section 120 is inclined, and the water in the first water guide section 120 collects in the drainage section 110 along the inclined path (first direction), which improves drainage effect, avoids the problem of localized water accumulation, and allows the water to flow smoothly.

[0097] The fact that the ceiling surface of the drainage plate 100 is horizontal may be understood as the sixth included angle θ2 formed by the first direction and the horizontal plane. The first water guide section 120 is formed by gradually recessing downward along the ceiling surface of the drainage plate 100 from one end away from the drainage section 110 toward a position communicating with the drainage section 110. In this case, the sixth included angle θ2 is the angle formed between the bottom of the first water guide section 120 and the horizontal plane, and the first direction is a diagonally downward direction.

[0098] Here, the bottom of the first water conducting section 120 may be an oblique line or a slope, and in some cases, the bottom of the first water conducting section 120 is a slope, and the slope may be a flat or curved surface, which can be specifically selected as needed.

[0099] In some cases, if the bottom of the first water conducting section 120 does not form a continuous slope or incline, but is, for example, stepped, it can still meet the water conducting demand.

[0100] As can be seen, the sixth included angle θ2 is 7° or less, and the small sixth included angle θ2 contributes to reducing the distance from the ceiling surface to the bottom surface of the drainage plate 100, enabling small-angle drainage, and further reducing the height size of the air duct component 200, reducing the space occupied by the air duct component 200, contributing to improving the storage space of the refrigeration equipment, and providing a large-capacity refrigeration equipment.

[0101] In some cases, the sixth included angle θ2 is set to 3°, which can meet the drainage demand of the drainage plate 100 and further reduce the height of the drainage plate 100 to achieve small-angle drainage. Of course, the sixth included angle θ2 can also be 1°, 2°, 4°, 5°, or 6°.

[0102] In some cases, the difference between the first water guide section 120 and the above-mentioned third water guide section 140 is that the first water guide section 120 is inclined toward the drainage section 110 within the drainage plate 100, and the third water guide section 140 is inclined toward the end of the drainage plate 100, that is, the inclination direction is different, but other structures and parameters may be set to the same, for example, the inclination angle may be the same.

[0103] As can be seen, the bottom surfaces of the corresponding drainage plates 100 of the multiple water guide sections arranged in parallel on the same side of the drainage section 110 are flush with each other, thereby improving the flatness of the bottom surface of the drainage plate 100, making the drainage plate 100 simple in appearance and easy to position and install.

[0104] Here, "arranged in parallel" may be understood to mean that a plurality of water guide sections are lined up in order on one side in the extension direction of the drainage section 110. Generally, a plurality of water guide sections are arranged in parallel on both sides of the drainage section 110, that is, the drainage section 110 is arranged between two rows of water guide sections. Of course, if the drainage section 110 is arranged at the end of the drainage plate 100, the water guide section is arranged on only one side of the drainage section 110.

[0105] As can be seen, the extension direction of the water guide portion is perpendicular to the air flow direction, so as to achieve sufficient heat exchange, thereby effectively extending the time that the air stays in the first cavity 282 .

[0106] As can be seen, the extension direction of the drainage section 110 and the air supply direction form an eighth included angle, which minimizes the discharge of wind along the extension direction of the drainage section 110, extends the time that the wind stays in the first cavity 282, and ensures the heat exchange effect.

[0107] Of course, the drainage section 110 may extend along the air supply direction, and water guide sections may be provided symmetrically on both sides of the drainage section 110, which is convenient for the water guide sections on both sides of the drainage section 110 to guide water uniformly and stably.

[0108] As shown in FIGS. 20 and 25, when the drainage section 110 extends along the air blowing direction, the water guide section is perpendicular to the air blowing direction, reducing the wind entering the water guide section as much as possible.

[0109] As can be seen, the recessed depth of the drainage section 110 is equal to or greater than the recessed depth of the water conducting section, as shown in Figures 24 and 25. In other words, the minimum depth of the drainage section 110 needs to be equal to or greater than the maximum depth of the water conducting section so that water from the water conducting section is collected in the drainage section 110 and pooling of water in the water conducting section is avoided.

[0110] 20, 21 and 24, a plurality of water guide sections are provided on both sides of the drainage section 110, all of which are parallel to each other, and the plurality of water guide sections guide water from different locations into the drainage section 110. By providing a plurality of water guide sections, it can be understood that both sides of the drainage section 110 are formed with a wave-like structure, which reduces the area of ​​the ceiling surface of the drainage plate 100 as much as possible, reduces water accumulation on the ceiling surface of the drainage plate 100, and allows the water received by the drainage plate 100 to be quickly discharged through the outlet 114 along the water guide sections and the drainage section 110.

[0111] 22 and 23, at least two drainage sections 110 are provided, and two or more drainage sections 110 have two or more outlets 114, realizing drainage at multiple positions and contributing to the rapid discharge of water in the drainage plate 100. When the area of ​​the drainage plate 100 remains unchanged, an increase in the number of drainage sections 110 can shorten the length of the water guide section, allowing water to enter the drainage sections 110 quickly.

[0112] Adjacent drainage sections 110 are a first drainage section 111 and a second drainage section 112, and between the first drainage section 111 and the second drainage section 112 there is a first water conduction area 123 located on the side of the first drainage section 111 and a second water conduction area 124 located on the side of the second drainage section 112, and the recessed depth of the water conduction section of the first water conduction area 123 gradually increases toward the first drainage section 111, and the recessed depth of the water conduction section of the second water conduction area 124 gradually increases toward the second drainage section 112. In other words, at the abutting position between the first water conduction area 123 and the second water conduction area 124, the recessed depth of the water conduction section is minimum, which contributes to the first water conduction area 123 directing the received water to the first drainage section 111 and the second water conduction area 124 directing the received water to the second drainage section 112, thereby shortening the length of the water conduction section and facilitating the collection of water in the drainage section 110.

[0113] 15, one drainage section 110 may be provided, in which case the outlet 114 of the drainage section 110 is arranged as far away as possible from the inlet of the fan 270. On both sides of the drainage section 110, a plurality of parallel water guide sections are provided, which shortens the water guide path of the water guide sections and contributes to faster water discharge.

[0114] As shown in Figures 12, 13, 15, 16 and 22 to 23, the drainage section 110 extends from front to rear, the outlet 114 is located at the rear end of the drainage plate 100, the water guide section extends in the left-right direction, and both the left and right sides of the drainage section 110 are formed in a wave-shaped structure. The installation of the wave-shaped plate is advantageous for collecting and discharging water, and in this case, the evaporator 230 does not need to be installed inclined downward along the front-to-rear direction.

[0115] The water guide section and the ceiling surface of the drain plate 100 form an included angle of less than 7°, that is, the drain plate 100 is formed with a water guide section that extends at an incline in the left-right direction, and the inclination angle of the water guide section does not affect the angle in the front-to-back direction of the drain plate 100. The drain section 110 extends from front to rear, and the drain section 110 forms a seventh included angle θ3 with the horizontal plane from front to rear, and the seventh included angle θ3 does not affect the change in height of the drain plate 100 in the front-to-back direction. However, from an overall perspective, the drain section 110 is installed in a local position on the drain plate 100, and the area of ​​the drain plate 100 occupied by the drain section 110 is relatively small, and the inclination angle of the local position on the drain plate 100 is somewhat large, so that the impact on the overall storage space within the compartment is relatively small and the volume within the compartment can be optimized.

[0116] In the above content, the water guide section may be at least one of the first water guide section 120 and the third water guide section 140, that is, the drainage plate 100 may be configured to have the above drainage section 110 and at least one of the first water guide section 120 and the third water guide section 140, and the structure of the drainage plate 100 is diverse.

[0117] As can be seen, as shown in Figures 24 and 25, the first water guide section 120 includes a first flow guide surface 121 arranged along the extension direction of the first water guide section 120, and in the direction from the ceiling surface to the bottom surface of the drainage plate 100, the first flow guide surface 121 approaches its opposite side surface; in other words, the vertical cross section of the first water guide section 120 converges from top to bottom, so that water that falls on the first flow guide surface 121 and the ceiling surface collects at the bottom of the first water guide section 120 and further collects along the first water guide section 120 to the drainage section 110.

[0118] Of the side surfaces on both sides of the first water conducting section 120 along its extension direction, at least one side surface is provided as a first flow conducting surface 121. The shape of the longitudinal cross section of the first water conducting section 120 may be an inverted triangle or an inverted trapezoid. As shown in Figures 24 and 25, both side surfaces on both sides of the first water conducting section 120 along its extension direction are first flow conducting surfaces 121, and both sides of the first water conducting section 120 can conduct water.

[0119] As can be understood, as shown in Figures 24 and 25, the drainage section 110 includes a second flow guide surface 113 arranged along the extension direction of the drainage section 110, and in the direction from the ceiling surface to the bottom surface of the drainage plate 100, the second flow guide surface 113 approaches its opposite side surface, so that the vertical cross section of the drainage section 110 converges from top to bottom, and water that falls on the second flow guide surface 113 and the ceiling surface collects at the bottom of the drainage section 110 and can then be discharged from the outlet 114.

[0120] Of the side surfaces on both sides of the drainage section 110 along its extension direction, at least one side surface is provided as a second flow guide surface 113. The cross section of the drainage section 110 may be shaped as an inverted triangle or an inverted trapezoid. As shown in FIG. 25 , both side surfaces on both sides of the drainage section 110 along its extension direction are second flow guide surfaces 113, and both sides of the drainage section 110 can guide water.

[0121] As shown in Figures 24 and 25, the first water guide section 120 is provided with a first flow guide surface 121, and the drainage section 110 is provided with a second flow guide surface 113, which sufficiently guides the water received by the drainage plate 100 so that it can be quickly discharged from the outlet 114.

[0122] In the above embodiment, the first flow direction surface 121 and the second flow direction surface 113 may be flat or curved, and specifically can be selected as needed.

[0123] As can be seen, the width of the water conducting portion at the first predetermined cross section in the extension direction of the water conducting portion gradually decreases toward the drainage portion 110. The water conducting portion gradually converges toward the drainage portion 110, which may be seen as contributing to the collection of water within the water conducting portion and the water within the water conducting portion entering the drainage portion 110.

[0124] The first predetermined cross section here may be understood as a cross section parallel to the ceiling surface of the drainage plate 100, and as a horizontal cross section in a state in which the drainage plate 100 is installed. The width of the water conducting section may be understood as the distance between two side walls in the extension direction of the water conducting section, and may be understood as the distance between two first flow conducting surfaces 121 in the case of the first water conducting section 120 as an example. Gradually reducing the width generally means continuously reducing the width, but reducing the width in steps is not excluded.

[0125] As can be seen, the second predetermined cross section in the extension direction of the drainage portion 110 has a width that increases toward the outlet 114. The defrost water received by the multiple water guides is collected toward the drainage portion 110, the amount of water is greatest at the position of the outlet 114 of the drainage portion 110, and the width of the drainage portion 110 increases, providing a larger drainage space and contributing to stable discharge of water.

[0126] The second predetermined cross section here may be understood as a cross section parallel to the ceiling surface of the drainage plate 100 and as a horizontal cross section in a state in which the drainage plate 100 is installed. The width of the drainage section 110 may be understood as the distance between two side walls in the extension direction of the drainage section 110, i.e., the distance between two second flow guide surfaces 113. Generally, the increase is gradual, but it is not excluded that the increase is in stages.

[0127] The first predetermined cross section may be parallel to and flush with the second predetermined cross section.

[0128] 22, the edge of the drainage plate 100 is folded upward to form a flange 150, which surrounds the drainage plate 100 and has a groove at a position corresponding to the outlet 114. The flange 150 serves to block water on the upper surface of the drainage plate 100 from overflowing outward, thereby ensuring that any water on the upper surface of the drainage plate 100 is discharged along the outlet 114 and that any water in the air passage component 200 is discharged through the drain port.

[0129] A local position of the flange 150 extends upward to form a positioning portion 151, and two adjacent positioning portions 151 are used to limit the position of the first heater 231 above the drainage plate 100, which simplifies the fixing method of the first heater 231 and the structure of the drainage plate 100.

[0130] If an opening is formed at the end of the water guide, there is no need to provide a flange.

[0131] In the above embodiment, the contour shape of the drainage plate 100 is related to the shapes of the evaporator 230 and the air passage component 200, and the shape of the drainage plate 100 is not limited. The contour shape of the drainage plate 100 may be rectangular, trapezoidal, circular, or other shapes. The shapes of the upper and lower surfaces of the drainage plate 100 are the same.

[0132] The drainage plate 100 in the above embodiment is applied to the air duct component 200, that is, the drainage plate 100 is provided below the evaporator 230, and there is no need for the evaporator 230 to be tilted downward in the front-to-rear direction, which solves the problem that the compartment internal volume is lost when the evaporator 230 has an inclination angle, and realizes defrosting and drainage at a small angle while ensuring the heat exchange efficiency within the air duct component 200, and reduces the vertical drop of the air duct component 200, contributing to maximizing the compartment internal volume.

[0133] Of course, in actual use, the evaporator 230 may be slightly inclined downward, but even if the evaporator 230 is not inclined downward, the drainage effect is not affected.

[0134] A vibrator (not shown) is further connected to the drain plate 100, and the vibrator provides a vibrating force according to the demand for defrosting. The opening and closing of the vibrator is closely related to the timing of defrosting, and the vibrator may operate synchronously with the defrosting operation or may be appropriately delayed from the defrosting operation.

[0135] The vibrator may be an eccentric motor, an ultrasonic vibrator, or an electromagnetic vibrator.

[0136] Hereinafter, based on the above-mentioned drainage plate 100, a drainage structure that connects the drainage plate 100 with a drainage pipe will be described.

[0137] As shown in Figures 2 to 13, the air passage component 200 further includes a first drainage member 260, which is connected to the opening 170 of the drainage plate 100 within the first cavity 282, and the first drainage member 260 and the fan 270 are located on different sides (e.g., adjacent sides) of the drainage plate 100, and the first drainage member 260 may be understood as a side drainage structure.

[0138] The first drainage member 260 is provided with a first drainage outlet 262, which is connected to a drainage pipeline (the drainage pipeline is a first drainage pipe 263), thereby discharging water received by the drainage plate 100.

[0139] The first drainage member 260 is configured with a drainage passage, and the cross-sectional area of ​​the drainage passage gradually decreases from top to bottom, ensuring that the drainage water at the position of the opening 170 is fully received, and further allowing the drainage water to be collected in the first drainage outlet 262.

[0140] 6 and 7, the first drainage member 260 covers as many of the openings 170 in the drainage plate 100 as possible, ensuring a seal at the connection points between the first drainage member 260, the air passage member 220, and the partition plate member 210, and preventing air and water leakage. As shown in FIGS. 5 and 7, some openings 170 do not correspond to the first drainage member 260 in order to indicate the positions of the openings 170; in actual application, the first drainage member 260 covers all of the openings 170.

[0141] The first drainage member 260 is configured with a through hole that communicates with the opening 170, and the area of ​​the through hole covers all of the openings 170, thereby ensuring drainage and sealing effects and preventing water leakage.

[0142] As will be understood, the first drainage member 260 is provided with at least one air intake port, that is, the first drainage member 260 is provided with at least one of a first air intake port 201 and a second air intake port 202. As shown in Figures 6 and 9, an example will be described in which the first drainage member 260 is provided with a first air intake port 201, which passes through the inside of the first drainage member 260 and communicates with the first cavity 282 to realize return air for the first compartment 410. The first air intake port 201 communicates with the first compartment 410 via the return air member 430, thereby performing return air.

[0143] 13 , the first drainage member 260 includes a first wall plate 264 and a second wall plate 265 disposed opposite to each other, the first wall plate 264 having a through hole, and the second wall plate 265 having a first air intake port 201. The first wall plate 264 faces the drainage plate 100, and the second wall plate 265 faces the cabinet 400. Here, the first wall plate 264 and the second wall plate 265 may be detachably connected or integrally molded. In some cases, the first drainage member 260 is configured as an integrally molded structure to avoid leakage at the connection points.

[0144] In addition, when the first drainage member 260 does not have the first air intake port 201, the partition member 210 is attached above the air passage member 220, and a first air intake port is opened in the partition member 210, so that the return air member 430 of the first compartment 410 enters the first cavity 282 through the first air intake port 201.

[0145] As shown in FIGS. 2 to 13 , the opening 170 of the drain plate 100 faces the first side of the first cavity 282, the second cavity 281 is located on the second side of the first cavity 282, and the fan 270 is provided within the second cavity 281. The first and second sides of the first cavity 282 are adjacent to each other. The first side of the first cavity 282 may be understood as at least one of the left and right sides, and the second side of the second cavity 281 may be understood as the rear side. The water discharge direction of the drain plate 100 differs from the air blowing direction of the first cavity 282, reducing water vapor carried by the wind, minimizing the impact of drainage on the fan 270, and reducing the amount of frost on the fan 270. In this case, the opening 170 of the drain plate 100 faces at least one of the left and right sides.

[0146] As shown in Figures 5 to 8, the drainage plate 100 includes a second water guide section 130, which is recessed relative to the ceiling surface of the drainage plate 100. The extension direction of the second water guide section 130 forms an included angle with the air supply direction above the drainage plate 100. The recessed depth of the second water guide section 130 gradually increases along a predetermined plane toward the first side of the second cavity 281. The second water guide section 130 forms an opening 170 toward the end of the first side of the second cavity 281. Water received by the second water guide section 130 is discharged from the opening 170 along the extension direction of the water guide section. The opening 170 communicates with the first drainage member 260, thereby discharging the water from the first drain port 262. The drainage plate 100 has a simple structure and good drainage effect. Furthermore, the return air from the first section 410 enters the first cavity 282 through the first air intake 201, and the wind enters the first cavity 282 from the left or right side and can flow along the second water guide section 130; the return air from the second section 420 enters the first cavity 282 through the second air intake 202, and the wind enters the first cavity 282 from the front side of the air duct component 200; the return air from the first section 410 and the return air from the second section 420 enter the first cavity 282 via different paths, which reduces contact between the two return airs and also reduces the amount of frost caused by the contact between the two return airs.

[0147] In this case, if the air supply direction above the drainage plate 100 is from front to back and the extension direction of the second water guide section 130 is left to right, the included angle between the extension direction of the second water guide section 130 and the air supply direction above the drainage plate 100 is 90°, and the second water guide section 130 can play a role in reducing the flow speed of the air within the first cavity 282, thereby extending the time the air stays within the first cavity 282 and optimizing the heat exchange effect.

[0148] The drainage plate 100 includes a second water guide section 130 extending leftward from a predetermined position and a second water guide section 130 extending rightward from the predetermined position. The drainage plate 100 has openings 170 facing both left and right sides. A first drainage member 260 is provided on both the left and right sides of the air-channel component 200, resulting in a simple structure and good water guide effect. Here, the predetermined position may be the symmetrical plane of the drainage plate 100 or a vertical plane extending along the front-to-rear direction. The predetermined plane may be an end face of the drainage section, and the predetermined faces of the second water guide sections extending to the left and right of the drainage plate may be the same vertical plane or different vertical planes.

[0149] Unlike the above embodiment, as shown in Figures 10 to 13, the drainage plate 100 provided in the air passage component 200 is configured to have a third water guide section 140, and the opening 170 of the third water guide section 140 is connected to the first drainage member 260.

[0150] When fan 270 is provided at the rear of air-duct component 200, first drainage member 260 is provided on at least one of the left and right sides of air-duct component 200, and the drainage method may be understood to be side drainage. Because fan 270 is provided at the rear of air-duct component 200, in this case, evaporator 230 and fan 270 drain water independently, defrost water from evaporator 230 is discharged from both the left and right sides through first drainage member 260, and defrost water flowing toward the fan and water condensed by encountering fan 270 can be discharged through a structure below fan 270, which may be a rear drainage structure described below or another structure capable of discharging water from second cavity 281.

[0151] Unlike the drainage method of the first drainage member 260 described above, as shown in Figures 10 to 16, the air passage component 200 further includes a fan cover 240, which defines a second cavity 281, the fan 270 is provided in the second cavity 281 of the fan cover 240, and the fan cover 240 is configured with a ventilation opening 244, and the second cavity 281 is connected to the first cavity 282 via the ventilation opening 244.

[0152] In some cases, the fan cover 240 and the fan 270 are both located on the rear side of the air passage component 200, and the second drainage member 290 is located on the side where the fan is located, and the second drainage member 290 provides a rear drainage method.

[0153] The fan cover 240 is provided with a second drainage member 290, which is provided inside the fan cover 240, or which is provided below the outside of the fan cover 240.

[0154] As shown in Figures 14 to 16, when the second drainage member 290 is provided inside the fan cover 240, the space inside the fan cover 240 can be fully utilized, the height of the air passage component 200 can be reduced, and the capacity of the refrigeration equipment can be increased.

[0155] A fan cover 240 is provided on the side of the drainage plate 100 where the outlet 114 is located, and one end of the fan cover 240 facing the drainage plate 100 communicates with the outlet 114 of the drainage plate 100. The fan cover 240 includes a first cover 241 and a second cover 242 located below the first cover 241, and the fan 270 is provided above the second cover 242. A third drain port 2423 is provided in the second cover 242, and water discharged from the outlet 114 of the drainage plate 100 flows along the second cover 242 to the third drain port 2423. The second cover 242 can receive water guided from the drainage plate 100, water dripping from the first cover 241, and water dripping from the fan 270, and can guide defrost water from the first cavity 282, thereby contributing to a simplified structure of the air passage component 200. In this case, the drainage plate 100 may adopt a structure having a drainage portion 110, and specific reference may be made to the above embodiment of the drainage plate 100. The outlet 114 of the drainage plate 100 faces rearward, and the second cover 242 is located behind the drainage plate 100, and the provision of the second cover 242 provides a rear drainage structure.

[0156] The second drainage member 290 defines a first water guide passage 2421 that communicates with the outlet 114 of the drainage plate 100, and includes a partition wall 2422 that protrudes upward along the surface of the second cover 242. The partition wall 2422 defines the first water guide passage 2421, and the fan 270 is located on the side of the partition wall 2422. The partition wall 2422 serves to separate the first water guide passage 2421 from the fan 270, preventing water from flowing into the fan 270 and reducing the impact of water on the fan 270.

[0157] The first water guide passage 2421 is inclined downward in a direction away from the outlet 114 of the drain plate 100 so that the water in the first water guide passage 2421 is discharged downward, which is simple in structure and has a good drainage effect. The end of the first water guide passage 2421 forms a third drain port 2423, which is connected to a drain pipe and discharges the water into the compressor compartment through the drain pipe.

[0158] Here, the partition 2422 may have a plate-like structure or a block-like structure protruding above the second cover 242, and can be specifically selected as needed. Of course, the partition 2422 may be a part detachably connected to the second cover 242, for example, a plate structure that is inserted into or engaged with the second cover 242, but the structure of the partition 2422 is not limited thereto and may be a structure that can achieve other partition functions.

[0159] A partition plate 2427 is provided between the drainage plate 100 and the second cover 242, and the partition plate 2427 communicates between the drainage plate 100 and the second cover 242 only through the outlet 114, with the other portions being separated by the partition plate 2427, thereby ensuring that the first cavity 282 and the second cavity 281 communicate through the ventilation opening 244 and the outlet 114, with the other portions being separated. The partition plate 2427 may be integrally formed with the second cover 242, or may be removably connected thereto.

[0160] The second cover 242 and the drain plate 100 may be two independent members, or the second cover 242 and the drain plate 100 are integrally molded as a single member.

[0161] A first air guide section 2424 and a second air guide section 2425 are provided inside the fan cover 240, and the first air guide section 2424, the second air guide section 2425, and the fan 270 cooperate to guide air to the first exhaust port 203 and the second exhaust port 204, ensuring that the air flows out through the corresponding paths. As shown in Fig. 15, the second cover 242 is provided with the first air guide section 2424 and the second air guide section 2425.

[0162] The fan 270 is mounted on the upper surface of the second cover 242 via a fan mounting base 271, and a plurality of second mounting posts 2426 are provided on the upper surface of the second cover 242. The fan mounting base 271 is fixed to the second mounting posts 2426, and by adjusting the height of the second mounting posts 2426 at different positions, the angle and direction of inclination of the fan 270 can be adjusted, and the structure is simple.

[0163] The upper surface of the second cover 242 is inclined diagonally downward in the direction away from the drain plate 100, i.e., toward the third drain outlet 2423, so that the defrost water on the surface of the second cover 242 can flow toward the third drain outlet 2423 under the action of gravity.

[0164] The second cover 242 is configured to have a water collecting portion 2428, which is located on the side of the second cover 242 facing the third drain outlet 2423, and the area of ​​the water collecting portion 2428 gradually decreases toward the third drain outlet 2423 and is connected to the third drain outlet 2423, so that the water collected by the water collecting portion 2428 can be discharged through the third drain outlet 2423. The area of ​​the water collecting portion 2428 gradually decreases toward the third drain outlet 2423, that is, the water collecting portion 2428 converges toward the third drain outlet 2423 so that the defrost water received by the second cover 2422 can be collected and then discharged.

[0165] Since the upper surface of the second cover 242 is inclined downward toward the third drain outlet 2423, the water collecting portion 2428 can also be inclined downward, which improves the drainage effect, but the water collecting portion 2428 is not limited to being inclined downward, and it is not excluded that the water collecting portion be installed horizontally.

[0166] The second cover 242 is provided with a heating element 226, which heats the second cover 242 to heat and defrost the fan cover 240 and its components, such as the fan 270. The heating element 226 may be a heating film formed on the second cover 242, or may be a heating plate located below the second cover 242. However, the structure of the heating element 226 is not limited thereto and may be any other structure capable of realizing heating and defrosting.

[0167] Unlike the above-described second drainage member 290, as shown in Figures 10 and 11, the second drainage member 290 may be located below the fan cover 240, and the second drainage member 290 and the outer surface of the fan cover 240 are sealed to form a second water guide passage that communicates with the outlet 114 of the drainage plate 100. The second water guide passage and the second cavity 281 are separated from each other; that is, the second water guide passage and the fan 270 are separated by the fan cover 240, which reduces the impact of water in the second water guide passage on components such as the fan 270.

[0168] The second drainage member 290 may have a U-shaped structure with a flange, or may be integrally molded below the second cover 242. The structure of the second drainage member 290 is diverse and can be selected as needed. If the drainage plate 100 has multiple outlets 114, multiple second drainage members 290 can be provided below the fan cover 240, so that the second water guide passage and the fan 270 do not interfere with each other. Below the air-duct component 200, local locations corresponding to the second drainage members 290 protrude downward, which allows the height of the local locations of the air-duct component 200 to be relatively large without affecting the height of other locations, and can also serve to expand the capacity of the refrigeration equipment.

[0169] The second water guide passage is inclined downward in a direction away from the outlet 114 of the drain plate 100 so that the water in the second water guide passage is discharged downward, which has a simple structure and a good drainage effect. The second drain member 290 is provided with a second drain port, which is connected to a second drain pipe 291, and the water is discharged into the compressor compartment through the second drain pipe 291.

[0170] Of course, the water guide passage (first water guide passage 2421 or second water guide passage) may be arranged horizontally, and the water guide passage does not increase the vertical size of the air duct component 200, which contributes to reducing the height of the air duct component 200 and further increases the storage space of the refrigeration equipment.

[0171] The fan cover 240 has wiring holes, which allow the electrical connection members of the air passage component 200 to be wired through the wiring holes, thereby realizing electrical connection, simplifying the structure, and facilitating wiring.

[0172] The mounting method of the fan 270 is different from the above method, that is, when the fan cover 240 is not provided, the drainage method is different from the above-mentioned first drainage member 260 and second drainage member 290. The air passage member 220 supports the drainage plate 100, which is located below the evaporator 230, and a water-conducting material 223 is provided on the side of the drainage plate 100 where the outlet 114 is located, one side of the water-conducting material 223 facing the outlet 114 and communicating with the outlet 114, and the other side of the water-conducting material 223 forms a drain port, whereby the water-conducting material 223 communicates with a third drainage pipe 2231, and water discharged from the outlet 114 of the drainage plate 100 flows along the water-conducting material 223 to the third drainage pipe 2231. The fan 270 is provided on one side of the evaporator 230, and the fan cover plate 243 is located between the fan 270 and the evaporator 230. The inlet of the fan 270 communicates with the first cavity 282 through a ventilation hole 244 in the fan cover plate 243. The fan cover plate 243 is provided outside the water-conducting material 223, and is fixed to the box liner main body 300. A cavity for attaching the fan 270 is enclosed between the fan cover plate 243 and the rear wall of the box liner main body 300, and this cavity communicates with the first cavity 282 through the ventilation hole 244 opened in the fan cover plate 243. Alternatively, the cavity for attaching the fan 270, which is enclosed by the fan cover plate 243 itself, communicates with the first cavity 282, and the fan cover plate 243 is fixed to the box liner main body 300. A third cavity is defined between the fan cover plate 243 and the water-guiding material 223, and the wind in the first cavity 282 passes through the third cavity before being guided to the fan 270.

[0173] Here, water guide material 223 may be understood as a part of air passage member 220 or as a part independent of air passage member 220, and can be specifically selected as needed. Fan cover plate 243 is a mounting member for fan 270, and the main function of fan cover plate 243 is similar to the main function of fan cover 240. Fan cover plate 243 or fan cover 240 is provided in one air passage component 200, and fan cover plate 243 is used in combination with water guide material 223, and fan cover 240 is used in combination with second drainage member 290. When air passage component 200 includes fan cover 240, fan cover 240 has ventilation openings 244 formed therein, whereby wind within first cavity 282 is discharged by fan 270 through ventilation openings 244.

[0174] The fan cover plate 243 is provided with a third air guide section 2431 and a fourth air guide section 2432, and the fan cover plate 243 is provided with a first exhaust port 203 and a second exhaust port 204, so that the fan 270 blows out air from the first exhaust port 203 and the second exhaust port 204.

[0175] The fan 270 and the mounting method of the fan 270 will be described below.

[0176] 5 to 16 , air-duct component 200 further includes fan 270, a rotation axis of fan 270 forms a first included angle α1 with the vertical direction, fan cover 240 is provided with ventilation opening 244, an inlet of fan 270 faces ventilation opening 244, second cavity 281 communicates with the air-delivery area of ​​first cavity 282 via ventilation opening 244, and second cavity 281 communicates with the exhaust opening of air-duct component 200. The air in first cavity 282 is drawn into second cavity 281 by fan 270 via ventilation opening 244 in fan cover 240, and under the action of fan 270, the air in second cavity 281 enters first compartment 410 or second compartment 420 via the exhaust opening. That is, the second cavity 281 and the first and second exhaust ports 203 and 204 can be adjusted to be on or off.

[0177] The first included angle α1 formed between the rotation axis of fan 270 and the vertical direction may be understood to mean that the front end of the rotation axis of fan 270 is lower or higher than the rear end. To meet the demands of ventilation and drainage, the angle of the first included angle α1 is made as small as possible, and the difference in height between the front end and the rear end of the rotation axis of fan 270 is made as large as possible, that is, fan 270 is installed as nearly horizontally as possible, thereby reducing the space occupied by fan 270 in the vertical direction and further reducing the size of air-duct component 200 in the vertical direction.

[0178] In this case, the ventilation opening 244 is offset from the drain outlet of the first cavity 282 to minimize the airflow at the drain outlet being sucked out by the fan 270, thereby extending the time for the air to exchange heat within the first cavity 282 and improving the heat exchange efficiency.

[0179] The fan cover 240 is fixed to the box liner body 300 , and the wind in the first cavity 282 passes through the second cavity 281 and is guided by the fan 270 .

[0180] As can be seen, the air passage component 200 further includes a fan cover 240, which includes a first cover 241 and a second cover 242, the first cover 241 having a flow directing surface 2411 facing the fan 270, a first side of the flow directing surface 2411 being higher than a second side of the flow directing surface 2411, and the first side of the flow directing surface 2411 and the second side of the flow directing surface 2411 being on opposite sides, and the fan cover 240 defines a second cavity 281, within which the fan 270 is provided. The first cover 241 serves to collect water vapor above the fan 270 and allows the collected water droplets to flow from the first side of the flow guiding surface 2411 to the second side of the flow guiding surface 2411. The provision of the first cover 241 promotes the collection and discharge of water vapor within the second cavity 281, reduces corrosion of the fan 270 caused by water vapor, and extends the life of the fan 270.

[0181] Here, by setting the first included angle α1 to 7° or greater, water collected on the first side of the flow directing surface 2411 flows along the slope of its surface to the second side, and the water is guided along the air passage member 220 below the fan 270 to the third drainage port 2423. This prevents water collected on the surface of the first cover 241 from dripping into the fan 270 and minimizes water from falling onto the fan 270. Here, the first side of the flow directing surface 2411 is higher than the second side of the flow directing surface 2411, and the surface of the first cover 241 facing the fan 270 may be an inclined flat surface or a curved surface. Having the flow directing surface 2411 as a flat surface simplifies the structure of the first cover 241 and makes it easier to process. Furthermore, water collected on the surface of the fan 270 falls and is discharged by gravity.

[0182] The first included angle α1 must be less than 70° to achieve the purpose of reducing the height, and the first included angle α1 may be less than 60°, 50°, 45°, 30°, 20° or 10°, and the smaller the first included angle α1, the smaller the height size of the air duct component 200.

[0183] If the first included angle α1 is less than 7°, the exhaust demand can be met and the height of the air-channel component 200 is smaller, but the water guide effect of the surface of the first cover 241 facing the fan 270 is poor, making it difficult to achieve sufficient drainage. If the first included angle α1 is less than 7°, the drainage problem of the fan cover 240 needs to be solved.

[0184] In some cases, the first cavity 282 and the second cavity 281 may be arranged side by side, or the second cavity 281 may be surrounded by the first cavity 282. The positional relationship between the first cavity 282 and the second cavity 281 is not limited to this, as long as the two cavities are connected to each other. For example, if the second cavity 281 is located behind the first cavity 282, the fan 270 may be inclined forward at a first included angle α1 or backward at a first included angle α1. For example, as shown in FIG. 14, the fan 270 may be inclined forward at a first included angle α1, or as shown in FIG. 8, the fan 270 may be inclined backward at a first included angle α1. That is, the upper end of the rotation axis of the fan 270 is inclined forward relative to the vertical direction to form a first included angle α1, or is inclined backward relative to the vertical direction to form a first included angle α1.

[0185] Here, the fan 270 is gradually inclined upward from front to back, i.e., the inlet of the fan 270 faces the airflow direction of the first cavity 282, which helps the wind in the first cavity 282 enter the inlet of the fan 270 and improves the ventilation effect. The fan 270 is gradually inclined downward from front to back, which improves space utilization. In all of the above-mentioned structures, the evaporator 230 and the fan 270 may share a drainage structure, thereby simplifying the structure, or the evaporator 230 and the fan 270 may employ independent drainage structures for drainage, thereby reducing the impact of drainage on the fan 270. As shown in FIGS. 5, 6, 12, and 13, the drainage water from the evaporator 230 is guided through the first drainage members 260 on both the left and right sides, and the drainage water from the fan 270 is discharged from the rear end.

[0186] As will be understood, the rotation axis of fan 270 is collinear with the central axis of ventilation opening 244, and in the process of drawing air in first cavity 282 into second cavity 281 through ventilation opening 244, the suction effect of fan 270 is good, contributing to the effect of circulating air in air-duct component 200. In some cases, the shape of ventilation opening 244 matches the shape of the inlet of fan 270 so that air in first cavity 282 can be drawn into second cavity 281 through ventilation opening 244 by fan 270.

[0187] The rotation axis of the fan 270 is collinear with the central axis of the ventilation opening 244, and the flow guide surface 2411 of the first cover 241 is generally set parallel to the fan 270, or the area of ​​the first cover 241 corresponding to the fan 270 is generally set parallel to the fan 270. A centrifugal fan is generally selected as the fan 270, and the centrifugal fan can change the flow direction of the air so as to send the air to the first section 410 or the second section 420. Of course, the fan 270 may also have other circulating airflow effects.

[0188] As can be seen, as shown in Figures 4 to 6, the first cover 241 is located above the fan 270, and the first side of the flow guide surface 2411 faces away from the drainage plate 100, and the second side of the flow guide surface 2411 faces toward the drainage plate 100. The first side of the flow guide surface 2411 is inclined upward at a second included angle α2 relative to the second side of the flow guide surface 2411, i.e., facing away from the drainage plate 100. The flow guide surface 2411 of the first cover 241 is inclined upward at a second included angle α2, that is, facing the air flow direction of the first cavity 282, which contributes to the wind in the first cavity 282 entering the second cavity 281, thereby improving the ventilation effect. It is also possible for the evaporator 230 and the fan 270 to share a drainage structure in order to simplify the structure. As shown in FIGS. 14 to 16 and 21, the air-course component 200 drains air from the second drain outlet or the third drain outlet 2423 at the rear end.

[0189] 12 to 25, the drainage plate 100 includes a water guide section and a drainage section 110. The drainage section 110 has an outlet 114. Water received by the drainage plate 100 flows along the water guide section to the drainage section 110 and is discharged from the outlet 114. Due to this structure, some wind also flows along the water guide section and the drainage section 110 to the outlet 114. By offsetting the outlet 114 from the ventilation opening 244, wind flowing toward the outlet 114 is prevented from being directly discharged from the ventilation opening 244. This extends the time for which the wind exchanges heat within the first cavity 282, thereby improving heat exchange efficiency. Here, when the second cavity 281 is located behind the first cavity 282, the direction away from the drainage plate 100 is from front to back. Of course, the first cavity 282 and the second cavity 281 may be provided on the left and right sides, and the direction away from the drain plate 100 is the left-right direction, and the operating principle is the same as the front-rear direction, so no further explanation will be given here. As shown in Figures 1 to 3, 10, 11 and 17 to 19, the second cavity 281 is located behind the first cavity 282 as an example.

[0190] As shown in Figures 1 to 3, 10, 11 and 17 to 19, the first cover 241 is located above the fan 270, and a first side of the flow guide surface 2411 faces the drainage plate 100, and a second side of the flow guide surface 2411 faces away from the drainage plate 100, and the second side of the flow guide surface 2411 is inclined downward at a third included angle α3 relative to the first side of the flow guide surface 2411, that is, the flow guide surface 2411 of the first cover 241 is inclined downward at the third included angle α3 in a direction away from the drainage plate 100, and the first cover 241 guides the water flow behind the fan 270 and contributes to the rapid discharge of collected water.

[0191] In some cases, the second included angle α2 and the third included angle α3 are set to the same angle as the first included angle α1 so that the rotation axis of the fan 270 and the central axis of the ventilation opening 244 are collinear, thereby ensuring the air flow effect within the air duct component 200 and the air circulation effect within the refrigeration equipment.

[0192] In the above embodiment, the components such as the drainage plate 100, the fan cover 240, and the water guide material 223 all need to be supported and insulated by the air passage component 220, and the structure of the air passage component 200 will be described below.

[0193] The air passage member 220 may be fixed to the box liner main body 300 by being fixedly connected to the partition plate member 210, or the air passage member 220 may be fixedly connected directly to the box liner main body 300.

[0194] The air passage member 220 includes a support plate and a second insulating layer 221 provided below the drainage plate 100, and the support plate is supported below the second insulating layer 221. The shape of the upper surface of the second insulating layer 221 conforms to the shape of the lower surface of the drainage plate 100, so that the second insulating layer 221 sufficiently insulates the drainage plate 100, reduces the diffusion of cold heat to the outside, and ensures heat exchange efficiency.

[0195] If the lower surface of the drainage plate 100 is curved, for example, wavy, the upper surface of the second insulation layer 221 is a corresponding curved surface, and if the lower surface of the drainage plate 100 is flat, the upper surface of the second insulation layer 221 is flat, and can be specifically set as needed.

[0196] Here, the support plate includes a first support portion 222 and a second support portion 225 inclined diagonally downward along the first support portion 222, the second support portion 225 and the outlet 114 of the drainage plate 100 are located on the same side of the air passage component 200, the first support portion 222 supports the second insulation layer 221, a third insulation layer 224 is provided above the second support portion 225, a water-conducting material 223 or a fan cover 240 is provided above the third insulation layer 224, and the second support portion 225 plays a role in supporting the third insulation layer 224 and components above the third insulation layer 224 (e.g., the water-conducting material 223 or the fan cover 240).

[0197] The first support part 222 and the second support part 225 are independent parts, such as plate members, and are attached by a removable connection method, such as insertion, locking, fasteners, etc., or the first support part 222 and the second support part 225 are an integrally molded structure, which can reduce the number of parts and simplify assembly. In some cases, the water guide material 223 and the drainage plate 100 are two independent parts, and of course, the water guide material 223 and the drainage plate 100 can also be molded into an integral structure.

[0198] An air intake port may be opened in air passage member 220, whereby return air from at least one of first compartment 410 and second compartment 420 enters first cavity 282 through the air intake port opened in air passage member 220. When an air intake port is opened in the support plate, as shown in FIG. 13 , a second air intake port 202 communicating with second compartment 420 is opened in the front end of first support part 222, whereby second compartment 420 returns air to first cavity 282 through second air intake port 202 in the front end of air passage component 200.

[0199] 36 to 38, a first air intake port 201 is provided on a first side of first cavity 282, and a second air intake port 202 is provided on a second side of first cavity 282, which may be understood as the cross sections of first air intake port 201 and second air intake port 202 perpendicular to their respective air intake directions forming an included angle. The air intaked by first air intake port 201 and the air intaked by second air intake port 202 are airs having different temperatures.

[0200] Air passage member 220 is provided with partition 2221, and the orthogonal projection of partition 2221 on first air intake 201 covers a partial area of ​​first air intake 201, and the orthogonal projection of partition 2221 on first air intake 201 is located at one end close to the second side of first air intake 201, and a predetermined distance a is provided between partition 2221 and first air intake 201, and air intake by first air intake 201 flows in the direction of partition 2221, and as the air flows, some of the air is guided along the extension direction of partition 2221 and some continues to flow along the air intake direction, and when first air intake 201 and second air intake 202 intake air simultaneously, the amount of air that crosses and comes into contact with the air intake by first air intake 201 and the air intake by second air intake 202 can be reduced.

[0201] Within the first cavity 282, a gap is provided between one end of the evaporator 230 facing the second side and the second air intake port 202, and most of the air intakes from the first air intake port 201 and the second air intake port 202 join together at this gap, come into contact with each other, and exchange heat, and then flow further along the evaporator 230 to the exhaust port. At the position of this gap, the partition 2221 plays a role in guiding a portion of the air intake by the first air intake port 201 in the extension direction of the partition 2221. Therefore, it reduces the amount of air that comes into contact and exchanges heat between the intake air of first intake port 201 and the intake air of second intake port 202, reduces the amount of frost that forms at one end of evaporator 230 close to the second side due to the difference in intake air temperature, avoids the effect of a large amount of frost on the second side on the intake air volume of first cavity 282, solves the problem of a short defrost cycle due to a large amount of frost on the second side, appropriately extends the defrost cycle, and plays a role in power saving. By providing partition 2221, the intake air through first intake port 201 and the intake air through second intake port 202 are kept on both sides of partition 2221 as much as possible.

[0202] 36 , for example, in a case where first air intake port 201 is aligned with the edge of air passage member 220, predetermined distance a is the distance from the first side edge of air passage member 220 to partition 2221. Note that predetermined distance a is set to ensure that an appropriate flow space is provided from first air intake port 201 to partition 2221, to facilitate the flow of air into first cavity 282, and to prevent partition 2221 from blocking the corresponding portion of first air intake port 201. Therefore, the value of predetermined distance a is not limited and can be selected as needed. An orthogonal projection may be understood as a projection of first air intake port 201 along the air intake direction of first air intake port 201.

[0203] Air passage member 220 may be formed with first air intake port 201 (not shown).

[0204] An evaporator 230 is provided in the first cavity 282, and a heat sink 234 of the evaporator 230 extends in a direction from the second air intake 202 to the exhaust port (from front to rear in the drawing), thereby allowing wind in the gap between the evaporator 230 and the second air intake 202 to flow to the exhaust port along the guide direction of the heat sink 234.

[0205] The partition 2221 extends in the direction from the second air intake 202 to the exhaust port, and a portion of the air taken in by the first air intake 201 flows into the evaporator 230 along the partition 2221. When the extension directions of the partition 2221 and the heat sink 234 are aligned, the partition 2221 cooperates with the heat sink 234 to guide the air in the direction of the exhaust port.

[0206] In the direction from first air intake 201 to partition 2221, air path member 220 is provided with guide surface 2222, which is a curved surface, partition 2221 is located at a first end of guide surface 2222 and is in contact with the first end, and a second end of guide surface 2222 extends toward a first wall surface that defines first air intake 201. A portion of the air that enters the first cavity 282 from the first air intake 201 can flow along the guide path of the guide surface 2222; in other words, this portion of the air flows along the curved surface of the guide surface 2222, and the flow of the portion of the air is changed by the guide surface 2222, and the portion of the air flows along the extension direction of the partition portion 2221, reducing the amount of air that flows along the air intake direction of the first air intake 201 and the second air intake 202 that comes into contact and exchanges heat.

[0207] In some cases, the second end of the guide surface 2222 is perpendicular to the first wall surface defining the first air inlet 201, so that the air taken in by the first air inlet 201 flows along the guide surface 2222 into the partition 2221. Of course, the second end of the guide surface 2222 can also form an obtuse or acute included angle with the first wall surface to make the air flow along the guide surface 2222, and the specific structure of the guide surface 2222 can be selected as needed.

[0208] As shown in Figures 37 and 38, the guide surface 2222 includes a flat portion 22222 and a curved portion 22221, one end of the curved portion 22221 is connected to the partition portion 2221, and the other end of the curved portion 22221 is connected to the flat portion 22222 and is in contact with the flat portion 22222, the flat portion 22222 extends toward the first wall surface, the curved portion 22221 plays a role in changing the direction of the air flow, the flat portion 22222 can guide the air to the curved portion 22221, and the flat portion 22222 cooperates with the curved portion 22221 to make the intake of air by the first air intake port 201 smoother.

[0209] In some cases, the flat portion 22222 extends until it is connected to the first wall surface. However, a gap may be provided between the flat portion 22222 and the first wall surface, and the specific positional relationship between the flat portion 22222 and the first wall surface is not limited.

[0210] The air passage member 220 is provided with a second air intake section, which is configured with a second air intake port 202, and has partition sections 2221 on both ends of the second air intake section, and the first side includes two side surfaces adjacent to the second side, i.e., first air intake ports 201 are provided on both sides adjacent to the second air intake port 202, and the partition sections 2221 on both ends of the second air intake section can each partition a portion of the air intake by the corresponding first air intake port 201, resulting in a simple structure and good symmetry.

[0211] Air passage member 220 is provided with a flow guide plate 2223, which connects the edge of air passage member 220 to partition section 2221. Flow guide plate 2223 is located below partition section 2221 and guide surface 2222, and can play a role in supporting partition section 2221, thereby holding partition section 2221 at a predetermined height position and ensuring a correspondence between the air intake by first air intake port 201 and partition section 2221. At the same time, the air intake by first air intake port 201 can flow toward the exhaust port of flow guide plate 2223.

[0212] The height of the partition 2221 is less than 1 / 3 of the height of the first air intake port 201, so that the partition 2221 separates a portion of the intake air in the vertical direction, and has a relatively small effect on the intake effect of the first air intake port 201, thereby ensuring the intake efficiency of the first air intake port 201.

[0213] The length of partition 2221 is ⅓ or less of the length of first air intake port 201, so that partition 2221 separates a portion of the intake air in the lengthwise direction, has a relatively small effect on the intake effect of first air intake port 201, and can ensure the intake efficiency of first air intake port 201. Here, the length of partition 2221 is the length extending along air passage member 220 in the direction of evaporator 230.

[0214] Partition 2221 is integrally formed with air passage member 220, and partition 2221 does not require separate processing and attachment, simplifying the assembly process and saving assembly time for air passage component 200. Alternatively, partition 2221 may be detachably connected to air passage member 220, and the structure and shape of partition 2221 may be selected or replaced according to actual needs, making the structure of air passage component 200 more flexible and diverse.

[0215] Air passage member 220 includes a support member and a heat insulating layer, and the support member serves to support the heat insulating layer and the members thereon, and is configured to have second air intake port 202. In some cases, partition 2221 is integrally formed with or removably connected to the support member, in which case guide surface 2222 is also part of the surface of the support member; of course, a situation in which partition 2221 is integrally formed with or removably connected to the heat insulating layer is not excluded.

[0216] The above-described embodiments of the partition section 2221 and the embodiments of the guide surface 2222 and the flow guide plate 2223 associated with the partition section 2221 may be provided on the partition plate member 210, and at least one of the partition plate member 210 and the air passage member 220 has the above-described functions.

[0217] Based on the above description of the drainage plate 100, the air passage member 220 supports the drainage plate 100 according to one embodiment. The air passage member 220 includes a support plate and a heat insulating layer located above the support plate, the support plate including the first support portion 222 and the second support portion 225, the heat insulating layer including the second heat insulating layer 221 and the third heat insulating layer 224, the second heat insulating layer 221 being provided above the first support portion 222, and the drainage plate 100 being provided above the second heat insulating layer 221.

[0218] 20 to 25, the drainage plate 100 has a structure including a drainage section 110 and a water guide section. The drainage section 110 has an outlet 114, the drainage section 110 is recessed relative to the ceiling surface of the drainage plate 100, the water guide section is connected to the drainage section 110, and the water guide section is recessed relative to the ceiling surface of the drainage plate 100. The extension direction of the water guide section and the air supply direction above the drainage plate 100 form a fifth included angle. The bottom of the water guide section is inclined along the first direction toward the drainage section 110, and the first direction and the ceiling surface of the drainage plate 100 form a sixth included angle θ2. The water guide section here may be understood as the first water guide section 120 in the above embodiment.

[0219] The upper surface of the second insulation layer 221 conforms to the underside of the drainage plate 100, and if the drainage plate 100 is a corrugated plate, the upper surface of the second insulation layer 221 is a conforming corrugated surface, and the shape of the underside of the second insulation layer 221 can be set as needed, and if the underside is a plane extending horizontally, then the underside of the air duct member 220 can also be arranged as a plane extending horizontally, so that the shape of the underside of the air duct component 200 is regular and the external structure is simple.

[0220] As shown in Figure 37, the lower surface of the second insulating layer 221 is configured with a first support slope inclined along a first direction, and the first support portion 222 is configured with a second support slope 2224 that matches the first support slope, and the first support slope and the second support slope 2224 are easy to process and can serve to reduce the thickness of the air channel component 200.

[0221] The second insulating layer 221 is further configured with a first support groove that fits into the drainage portion 110, and the first support portion 222 is configured with a second support groove 2225 that fits into the first support groove, and an opening 170 at the rear end of the second support groove 2225 is connected to the drainage structure so as to discharge the defrost water received by the drainage plate 100.

[0222] The evaporator 230 above the drain plate 100 will now be described.

[0223] 18 to 20, the evaporator 230 is placed horizontally in the first cavity 282 of the air passage component 200, and the drain plate 100 serves to receive defrost water below the evaporator 230. The ceiling surface of the drain plate 100 is parallel to the bottom surface of the evaporator 230. Here, the upper part of the drain plate 100 in FIGS. 1, 2, 10, and 11 is used to place the evaporator 230, but the structure of the evaporator 230 is not shown.

[0224] The evaporator 230 being horizontally oriented may be understood to mean that the height of the evaporator 230 is less than its length and width.

[0225] The drain plate 100 is located below the evaporator 230, and the drain plate 100 is provided with a water guide portion recessed into the ceiling surface, and the included angle between the evaporator 230 and the horizontal plane is equal to or smaller than a predetermined included angle.

[0226] Here, the included angle between the evaporator 230 and the horizontal plane is equal to or smaller than a predetermined angle, the end of the evaporator 230 facing the exhaust port is lower than the end of the evaporator 230 facing the inlet port, and the connecting line between the end of the evaporator 230 facing the exhaust port and the end of the evaporator 230 facing the inlet port may be understood to form the predetermined angle with the horizontal plane, and this connecting line may be located on the bottom surface of the evaporator 230 or on a symmetrical plane in the height direction. If the evaporator 230 has a rectangular parallelepiped shape, both the bottom surface and the symmetrical plane of the evaporator 230 form the predetermined angle with the horizontal direction.

[0227] In some cases, the predetermined angle may be 7° or less, and may be at least one of 1°, 2°, 3°, 4°, 5°, 6°, and 7°. Note that the reason the predetermined angle is limited to 7° or less is to reduce the height of air-channel component 200, and if the height of air-channel component 200 is not strictly limited, the predetermined angle can be increased appropriately.

[0228] Alternatively, the drainage plate 100 may have a water guide section recessed into the ceiling surface, and the evaporator 230 may be arranged horizontally within the first cavity 282, in which case the height of the air passage component 200 may be made sufficiently small.

[0229] In order to reduce the vertical space occupied by the evaporator 230, the angle between the evaporator 230 and the horizontal plane is less than a predetermined angle, so that the height of the entire air-duct component 200 can be reduced and the purpose of increasing the capacity of the refrigeration equipment can be achieved.

[0230] Here, referring to the structure of the drainage plate 100 shown in Figures 3 to 14, the specified angle may be 7°, which can meet the drainage requirements of the defrost water of the evaporator 230 and at the same time reduce the overall height of the air duct component 200.

[0231] As can be understood, the evaporator 230 may be horizontally mounted above the drainage plate 100, which may be understood as the bottom surface of the evaporator 230 being parallel to the horizontal plane, and compared with the situation where the evaporator 230 is installed at an angle, the height of the installation space required for the horizontally installed evaporator 230 is reduced, thereby reducing the height-wise size of the air duct component 200 accordingly, and further reducing the space within the box liner body 300 occupied by the air duct component 200, so that if the external size of the box liner body 300 remains unchanged, the capacity of the box liner body 300 can be effectively improved to provide a large-capacity refrigeration equipment.

[0232] In this case, the installation state of the drainage plate 100 is not limited, and the ceiling surface of the drainage plate 100 is parallel to the bottom surface of the evaporator 230, or the ceiling surface of the drainage plate 100 is inclined diagonally downward from front to back relative to the bottom surface of the evaporator 230.

[0233] As can be seen, the ceiling surface of the drainage plate 100 is flat and parallel to a horizontal plane, i.e., the bottom surface of the evaporator 230 and the ceiling surface of the drainage plate 100 are both horizontally disposed, and the ceiling surface of the drainage plate 100 is located below the evaporator 230. The bottom surface of the evaporator 230 is parallel to or in contact with the ceiling surface of the drainage plate 100, which reduces the gap between the evaporator 230 and the drainage plate 100 and can prevent the wind in the first cavity 282 from flowing directly into the ventilation opening 244 through the gap between the evaporator 230 and the drainage plate 100, contributing to sufficient heat exchange of the wind within the first cavity 282.

[0234] Furthermore, by making the gap between the evaporator 230 and the drainage plate 100 as small as possible, the speed at which the wind flows from the gap between the evaporator 230 and the drainage plate 100 to the ventilation opening 244 is reduced, and the time that the wind stays in the first cavity 282 is extended, so that the wind can exchange heat sufficiently with the evaporator 230 in the first cavity 282 before flowing out, thereby ensuring heat exchange efficiency.

[0235] In the above embodiment, the evaporator 230 is part of a refrigeration system in a refrigeration equipment, and the refrigeration system includes a compressor, a condenser, a throttle element, and the evaporator 230, and the refrigerant in the refrigeration system evaporates in the evaporator 230 to absorb heat and provide a refrigerated environment for the air in the first cavity 282.

[0236] The following describes the structure of evaporator 230. Note that, although the description will be made using an example in which evaporator 230 is attached to an air passage component, evaporator 230 is not limited to being applied to air passage component 200, and may be attached to other application environments.

[0237] The evaporator 230 includes a heat exchange tube 233 and a heat sink 234 connected to the heat exchange tube 233, and the heat sink 234 is configured to have a ventilation section 23421 through which the air intake through the first air intake port 201 passes, thereby allowing the air intake through the first air intake port 201 to flow through the ventilation section 23421 into the inside of the evaporator 230 and allowing the air intake through the first air intake port 201 to exchange heat sufficiently.

[0238] In addition, the ventilation section 23421 may be opened in some of the heat sinks 234, or the ventilation section 23421 may be opened in all of the heat sinks 234, and specifically, this can be selected as needed.

[0239] Hereinafter, an example will be described in which some of the heat sinks 234 have ventilation sections 23421 formed therein.

[0240] The evaporator 230 includes a heat exchange tube 233, a first heat sink 2341, and a second heat sink 2342. The first heat sink 2341 and the second heat sink 2342 are both connected to the heat exchange tube 233. A plurality of the first heat sinks 2341 are arranged in parallel to form a first heat dissipation section. A second heat sink 2342 is provided on at least one side of the first heat dissipation section. (When the evaporator is installed in the air passage component, the second heat sink 2342 is located between the first heat sink 2341 and the first air intake 201.) 2342), the second heat sink 2342 is configured to have a ventilation section 23421 through which the air taken in by the first air intake port 201 passes, and as a result, a part of the air taken in by the first air intake port 201 is diverted into the inside of the evaporator 230 via the ventilation section 23421, and further the amount of air that crosses and comes into contact with the air taken in by the first air intake port 201 and the air taken in by the second air intake port 202 to exchange heat is reduced, and the amount of frost that is condensed by the air taken in by the first air intake port 201 and the air taken in by the second air intake port 202 coming into contact with each other to exchange heat is reduced.

[0241] The second heat sink 2342 of the evaporator 230 diverts the air intake through the first air intake port 201, which has little impact on the overall structure of the air path component 200. It is sufficient to replace some of the heat sinks 234 with the second heat sink 2342 having the ventilation section 23421, which has a simple structure and a relatively good air intake diversion effect.

[0242] Here, the second heat sink 2342 is located on at least one side of the first heat sink 2341. That is, if a first air intake port 201 is provided on one side of the air-path component 200, the second heat sink 2342 is located on the corresponding side. If a first air intake port 201 is provided on both opposing sides of the air-path component 200, a second heat sink 2342 is provided on both sides of the first heat sink 2341. The surface of the second heat sink 2342 faces the first air intake port 201, the second air intake port 202 is located at one end of the second heat sink 2342, and the exhaust port is located at the other end of the second heat sink 2342.

[0243] The number of second heat sinks 2342 can be set as needed, and one or more second heat sinks 2342 may be provided. When one second heat sink 2342 is provided, part of the air taken in by the first air intake port 201 flows between the second heat sink 2342 and the first heat sink 2341 through the ventilation section 23421, and flows along the space between the second heat sink 2342 and the first heat sink 2341 toward the exhaust port. When multiple second heat sinks 2342 are provided, the air flows through the ventilation section 23421 of the second heat sink 2342, along the space between adjacent second heat sinks 2342 and the space between the second heat sink 2342 and the first heat sink 2341, and flows to the exhaust port, providing a larger air flow space and better airflow.

[0244] The ventilation portions 23421 of adjacent second heat sinks 2342 penetrate along a straight line, that is, of two adjacent second heat sinks 2342, the orthogonal projection of the ventilation portion 23421 of one second heat sink 2342 covers the orthogonal projection of the ventilation portion 23421 of the other second heat sink 2342, so that some of the wind can flow smoothly through the ventilation portion 23421 in the direction of the first heat sink 2341.

[0245] The ventilation sections 23421 of adjacent second heat sinks 2342 are staggered and communicate with each other, that is, the orthogonal projection of the ventilation section 23421 of one second heat sink 2342 of two adjacent second heat sinks 2342 covers part of the orthogonal projection of the ventilation section 23421 of the other second heat sink 2342, or the orthogonal projections of the ventilation sections 23421 of two adjacent second heat sinks 2342 do not intersect, thereby allowing some of the wind to flow along the extension direction of the second heat sinks 2342.

[0246] Here, two adjacent second heat sinks 2342 may have ventilation portions 23421 that penetrate in a straight line, and ventilation portions 23421 that communicate with each other in a staggered manner, resulting in more diverse structures.

[0247] When multiple second heat sinks 2342 are provided, the cross-sectional area of ​​the ventilation section 23421 can be gradually reduced in the direction from the outside of the evaporator 230 toward the first heat sink 2341, and the amount of intake air passing through the ventilation section 23421 toward the first heat sink 2341 is reduced.The reduction in the cross-sectional area of ​​the ventilation section 23421 has little effect on the flow of air, and the heat dissipation area of ​​the second heat sink 2342 can be secured.

[0248] The ventilation portion 23421 includes at least one of a closed loop through-hole and a through-hole with an opening, so that the ventilation portion 23421 has a diverse structure and is easy to process.

[0249] The shape of the ventilation portion 23421 is at least one of a rectangle, a circle, an oval, a trapezoid, and a triangle, and the shape of the ventilation portion 23421 is diverse and the structure is simple.

[0250] Here, the shape of the ventilation section 23421 is at least one of a closed rectangle, a circle, an ellipse, a trapezoid, and a triangle, or the shape of the ventilation section 23421 is at least one of a rectangle, a circle, an ellipse, a trapezoid, and a triangle with an opening, for example, a rectangle with one end open, a circle with a cutout, an ellipse with a cutout, etc.

[0251] Of course, the shape of the ventilation portion 23421 is not limited to the above-mentioned shape, and the specific shape of the ventilation portion 23421 can be set as needed.

[0252] A first air intake port 201 is provided on both sides of the evaporator 230, and a plurality of first heat sinks 2341 are arranged in parallel to form a first heat dissipation section, and second heat sinks 2342 are arranged symmetrically on both sides of the first heat dissipation section. A ventilation section 23421 is provided at each position corresponding to the two first air intake ports 201 of the evaporator 230, ensuring that a portion of the air intake by both first air intake ports 201 can be diverted through the ventilation section 23421.

[0253] As shown in FIG. 13, return air members 430 are provided on both the left and right sides of air passage component 200, and return air members 430 communicate with first air intake port 201, realizing intake of air on both sides of air passage component 200.

[0254] The first heat sink 2341 and the second heat sink 2342 are provided above the drainage plate 100 so that the drainage plate 100 receives the defrost water of the evaporator 230, which simplifies the structure and makes it easy to install the evaporator 230.

[0255] The evaporator 230 may further be provided with a gravity sensor, which acquires a change in weight of the evaporator 230 and determines whether the evaporator 230 needs to defrost based on the change in weight. The evaporator 230 may further be provided with a vibrator, which provides a vibration force to assist in defrosting.

[0256] The heating structure for defrosting the inside of the air passage component 200 will be described below.

[0257] As shown in FIG. 20 , in some cases, a first heater 231 is provided above the drainage plate 100, that is, the first heater 231 is provided between the drainage plate 100 and the evaporator 230. When the evaporator 230 needs to defrost, the first heater 231 is turned on, and the heat generated by the first heater 231 is used to heat the frost on the surface of the evaporator 230. In some cases, a locking groove for attaching the first heater 231 is provided in the heat sink 234 of the evaporator 230, and the first heater 231 is locked to the heat sink 234 by the locking groove. The locking groove may be provided at a position near the bottom of the heat sink 234 so that the first heater 231 is located between the drainage plate 100 and the heat exchange tube 233. In this case, the installation of the first heater 231 is simple and the defrosting effect is good.

[0258] Of course, the heating structure for defrosting is not limited to being provided between the drain plate 100 and the evaporator 230, and in some cases, the heating structure may be provided between the heat exchange tubes 233 of the evaporator 230. For example, the heating structure is a second heater 232 inserted into the heat sink 234 of the evaporator 230, which has a simple insertion structure and is easy to install, contributing to improved installation efficiency. The heat sink 234 has an installation hole 2343, and the second heater 232 is inserted into the installation hole 2343, which has a simple structure and is easy to install and remove.

[0259] The second heater 232 extends along the first end of the evaporator 230 to the second end, the first end and the second end being opposite ends, thereby providing sufficient heat to the evaporator 230, and the second end and the first end here are ends that form an included angle with the extension direction of the heat sink 234, for example, the left end and the right end of the evaporator 230.

[0260] The second heater 232 may be inserted between the two rows of heat exchange tubes 233 so as to uniformly heat and defrost the two upper and lower rows of heat exchange tubes 233. In this case, the heat exchange efficiency between the second heater 232 and the heat exchange tubes 233, and between the second heater 232 and the heat sink 234 in the heat exchange tubes 233, is higher, and the efficiency of heating and defrosting can also be improved.

[0261] The second heaters 232 are distributed in multiple layers along the height direction of the evaporator 230 so as to heat multiple positions of the evaporator 230.

[0262] The second heater 232 includes a plurality of fixedly connected heating elements, which are fixedly connected together and directly inserted into the heat sink 234 during the assembly process, making the assembly simple and efficient.

[0263] The second heater 232 includes a plurality of heating elements that are independent of each other, and the positions of the heating elements are flexible, and the heating elements can be easily replaced individually, making it even easier to attach and detach the heating elements.

[0264] When the second heater 232 includes multiple independent heating materials, the heating materials may be staggered along the height direction of the evaporator 230, thereby reducing the number of heating materials and still allowing for sufficient defrosting of the entire evaporator 230.

[0265] If a heating structure is not provided between the drainage plate 100 and the evaporator 230, the evaporator 230 can be placed directly on the drainage plate 100, which can effectively reduce the gap between the evaporator 230 and the drainage plate 100, and can also serve to reduce wind speed and improve heat exchange efficiency.

[0266] The heating structure may be provided as a heating material 160, which is attached to the surface of the drainage plate 100, or the heating material 160 may be integrated into the drainage plate 100 into an integral structure, or the drainage plate 100 having the heating material 160 may be attached below the evaporator 230 of multiple structures, and this drainage plate 100 can not only receive and discharge defrosting water, but also heat and defrost, so that the drainage plate 100 has a dual function, and this drainage plate 100 is attached within the air duct component 200, which can reduce the height of the air duct component 200.

[0267] The drainage plate 100 having the heating material 160 may be attached below the evaporator 230 that is placed horizontally. Alternatively, the drainage plate 100 having the heating material 160 may be attached below the evaporator 230 that is placed vertically inside the cabinet 400. The application of the drainage plate 100 is not limited here.

[0268] The heating material 160 may be integrally molded with the drainage plate 100 according to any one of the above embodiments, or the heating material 160 may be integrally molded with another drainage plate 100 that can receive and discharge defrost water, so that the drainage plate 100 can be widely applied to many occasions.

[0269] The heating material 160 covers the underside of the drainage plate 100, and the upper surface of the drainage plate 100 is used to receive defrosting water. The heating material 160 located on the underside of the drainage plate 100 can avoid direct contact with water, which can prevent the occurrence of electric leakage accidents due to circuit failure, and improve the safety performance of the refrigeration equipment.

[0270] Of course, if the waterproof performance of the heating material 160 is ensured, the heating material 160 may cover the upper surface of the drainage plate 100.

[0271] The heating material 160 may be a heating wire or a heating film provided on the surface of the drainage plate 100 .

[0272] The following description will be given taking an example in which the heating material is a heating film.

[0273] The heating material 160 includes an insulating layer and a composite heating layer provided on the underside of the insulating layer, and the insulating layer is connected to the underside of the drainage plate 100. The insulating layer provides insulation protection between the drainage plate 100 and the composite heating layer, thereby reducing the risk of electrical leakage. In this case, the material of the drainage plate 100 is not limited, and the drainage plate 100 can be made of steel, which is easy to process and can ensure the heat conduction effect of the drainage plate 100.

[0274] The heating material 160 includes a composite heating layer, and the drainage board 100 has an insulating and heat-conducting structure. The composite heating layer is provided on the underside of the drainage board 100, so that the drainage board 100 has both heat-conducting and insulating functions, eliminating the need for an insulating layer. This simplifies the processing of the drainage board 100 and contributes to improving production efficiency. Here, the drainage board 100 may have a composite structure of ceramic and glass fiber material.

[0275] Here, the composite heating layer of the heating material 160 may be a graphene heating layer, a nano heating layer, or a carbon fiber heating layer, and a heating layer that combines multiple types of electric heating materials. When the composite heating layer is energized, it can convert electrical energy into thermal energy for the heating material 160 to provide heat for defrosting. For example, the composite heating layer is a graphene heating layer, which is a planar film made of carbon atoms with a hexagonal honeycomb lattice and only one atom thick, thereby allowing the thickness of the heating material 160 to be controlled.

[0276] Furthermore, if the heating material 160 is provided on the underside of the drainage plate 100, an insulating and heat-insulating layer must be provided below the composite heating layer to reduce downward heat diffusion and ensure thermal efficiency. The composite heating layer and the insulating layer, the composite heating layer and the drainage plate 100, and the insulating and heat-insulating layer and the composite heating layer are bonded using thermally conductive adhesive layers, which not only achieve heat conduction but also ensure a reliable connection between each layer.

[0277] The heating material 160 includes multiple heating areas distributed along a set direction, and the heating efficiency per unit area of ​​the heating areas gradually increases along the set direction. According to the difference in the amount of frost at different positions, the heating efficiency of the corresponding heating areas can be adjusted, thereby realizing quick and sufficient defrosting and further reducing power consumption.

[0278] When the composite heating layer uses a graphene heating layer, the grid distribution of the graphene heating layer in different heating regions is different, resulting in different resistance distributions of the graphene heating layer in different heating regions. The underside of the drainage plate 100 may have two or more graphene heating layers with different resistances. Furthermore, the graphene heating layers with different resistances may be connected in series, in parallel, or even in different circuits.

[0279] The heating material 160 in the above embodiment is applied to the above air duct component 200 and used for defrosting the evaporator 230, which can reduce the space occupied by the heater, reduce the height of the air duct component 200, and further reduce the volume of the air duct component 200. A refrigeration equipment having such an air duct component 200 can appropriately increase the storage space and increase the capacity of the refrigeration equipment.

[0280] The drain plate 100 having the heating material 160 in the above embodiment can be used in combination with at least one of the first heater 231 and the second heater 232 so as to improve defrosting efficiency.

[0281] The heating material 160 can be applied to the drainage board 100 according to the above embodiment, but is not limited thereto, and the heating material 160 can also be applied to drainage boards of other structures.

[0282] The above-mentioned heating structure for defrosting needs to be electrically connected to an external power source of the air passage component 200 via a conductor, and the conductor can be routed through a wiring hole opened in the above-mentioned fan cover 240, making the structure simple and easy to assemble.

[0283] The structure of the partition plate member 210 will be described below.

[0284] The partition plate member 210 and the air passage member 220 define a first cavity 282, an air intake port, and an air exhaust port, and an evaporator 230 and a drain plate 100 are provided in the first cavity 282. The air taken in by the air intake port exchanges heat in the first cavity 282 before being discharged from the air exhaust port, and the air exhaust port sends air into the compartment to provide a refrigeration environment for the refrigeration equipment. When the air intake port includes a first air intake port 201 and a second air intake port 202, the first air intake port 201 and the second air intake port 202 contain intake air of different temperatures.

[0285] The partition member 210 may be fixedly connected to the box liner body 300, for example, by welding, fastening, fasteners, or the like at the edge of the partition member 210. As shown in Figures 6 and 20, the partition member 210 includes a first plate 211 and a second plate 212, and a first insulating layer 213 is provided on the first plate 211 and the second plate 212. The first insulating layer 213 is removably provided between the first plate 211 and the second plate 212, or the first insulating layer 213 is foam-molded integrally with the first plate 211 and the second plate 212.

[0286] When the first insulating layer 213 is foam-molded integrally with the first plate 211 and the second plate 212, the first plate 211 and the second plate 212 are first fixed and attached to the box liner body 300. The first insulating layer 213 is foam-molded integrally with the insulating layer of the cabinet 400, which improves the sealing performance between the partition plate member 210 and the box liner body 300 and prevents gases from mixing between the first compartment 410 and the second compartment 420.

[0287] As shown in Figures 6 and 20, the partition plate member 210 further includes a third plate body 214, and the third plate body 214, the first plate body 211, and the second plate body 212 define an installation space, and the portion defining the installation space may be called an installation portion, and the third plate body 214 is located in front of the air passage component 200, and the installation space is located in front of the partition plate member 210, and the installation space is used to install functional components such as a controller, a lighting module, an interaction module, a display module, etc. When the second air intake 202 is provided on the front side of the air passage component 200, the portion (mounting portion) that defines the mounting space of the partition member 210 is located at the front end of the second air intake 202, and the portion (mounting portion) that defines the mounting space serves to cover the second air intake 202 at the front end, thereby hiding the second air intake 202 and communicating the lower side of the second air intake 202 with the second compartment 420.

[0288] Note that second air intake 202 is not limited to being provided on the front side of air passage component 200, and second air intake 202 may be provided at a position closer to the front on the lower side of air passage component 200.

[0289] As shown in FIGS. 26 to 28, the partition plate member 210 and the air passage member 220 define a first cavity 282, a first air intake port 201, a second air intake port 202, and an air exhaust port, the first air intake port 201 and the second air intake port 202 contain intake air of different temperatures, the first air intake port 201 is located on a first side of the air passage component 200, the second air intake port 202 is located on a second side of the air passage component 200, the first side and the second side are adjacent to each other, or the first air intake port 201 and the second air intake port 202 are located on the same side, and the partition plate member 210 has an internal recess recessed toward the inside of the partition plate member 210. The internal recess is configured to guide a portion of the air intake by at least one of the first air intake port 201 and the second air intake port 202 so that it is diverted into the internal recess, that is, a portion of the air intake by at least one of the first air intake port 201 and the second air intake port 202 is diverted to the corresponding internal recess, thereby reducing the amount of air intake by the first air intake port 201 and the second air intake port 202 that crosses and comes into contact, reducing the amount of frost formation in the area where the intake air crosses and comes into contact, and further extending the time interval between two defrosting operations, reducing the number of defrosting operations, and lowering the power consumption for defrosting.

[0290] For example, if the first air intake port 201 and the second air intake port 202 are located on different sides and their air intake directions intersect, during the air intake process, part of the air from the first air intake port 201 is guided along the extension direction of the corresponding internal recess, and part continues to flow along the air intake direction, and when the first air intake port 201 and the second air intake port 202 simultaneously intake, the air continuing to flow along the air intake direction and the air intake by the second air intake port 202 intersect, reducing the amount of air that intersects between the air intake by the first air intake port 201 and the air intake by the second air intake port 202. The principle of providing an internal recess in the area corresponding to the second air intake port 202 is the same, and will not be further described here.

[0291] For example, if the first air intake port 201 and the second air intake port 202 are located on the same side (for example, both are located on the front side) and have the same air intake direction, the extension direction of the internal recess matches the extension direction of the corresponding air intake port, and some of the air intake by the first air intake port 201 flows along the extension direction of the corresponding internal recess, and another part of the air intake by the first air intake port 201 continues to flow along that flow direction.

[0292] As shown in FIG. 26, the internal recess includes a first internal recess 2121, which extends along the second side of the partition member 210 to the third side by a first predetermined width L1 and a first predetermined length L2, the second air intake port 202 is located on the second side, the third side is a side not adjacent to the second side, and the third side may be the side on which the air exhaust port is located, the first internal recess 2121 is close to the edge of the first side of the partition member 210, and the first air intake port 201 is located on the first side.

[0293] Of the intake air that enters the first cavity 282 from the first intake port 201, part flows along the intake direction of the first intake port 201 and crosses and comes into contact with the air intake by the second intake port 202, and the other part flows along the extension direction of the first internal recess 2121, and the first internal recess 2121 acts as a guide and divider, thereby reducing the amount of air that merges with the air intake by the first intake port 201 and the air intake by the second intake port 202, and further reducing the amount of frost formation.

[0294] Here, the first predetermined width L1 may be set to be equal to or less than the minimum distance from the first air intake port 201 to the second air intake port 202, and the first predetermined length L2 may be set to be equal to or less than the length of the evaporator 230, the length direction of the evaporator 230 being the direction from the air intake port to the air exhaust port.

[0295] As shown in Figure 26, the first internal recess 2121 is configured to have a first ceiling surface 2123 and a first guide surface 2122 connected to the first ceiling surface 2123, and the first guide surface 2122 is inclined downward in a direction away from the first ceiling surface 2123, and the first guide surface 2122 is located on the side away from the first air intake port 201, and the first guide surface 2122 guides the wind toward the exhaust port, preventing the wind from accumulating in the groove defined by the first internal recess 2121 and ensuring a circulating flow effect of the wind.

[0296] When the first side of the first cavity 282 includes two or more side surfaces, for example, the first sides are provided as opposing left and right sides, the first air intake ports 201 are provided on the left and right sides of the air passage component 200, and first internal recesses 2121 are provided symmetrically on both sides of the partition member 210, each of the first internal recesses 2121 corresponding to one first air intake port 201, and it is ensured that a portion of the air intake by each first air intake port 201 is diverted by the first internal recesses 2121.

[0297] Here, the first guide surface 2122 may be provided on the rear side, left side, or right side of the first internal recess 2121. As shown in Fig. 26, one first guide surface 2122 is located on the rear side of the first internal recess 2121, and the other first guide surface 2122 is located on the left side of the first internal recess 2121. Fig. 26 is a diagram for showing first guide surfaces 2122 at different positions, and in actual application, the two first internal recesses 2121 are generally provided symmetrically.

[0298] As shown in Figures 27 and 28, the internal recess includes a second internal recess 2124, one side of which faces the second air intake port 202, so that the second internal recess 2124 guides some of the air intake by the second air intake port 202 to flow along the groove defined by the second internal recess 2124, and some of the air intake by the second air intake port 202 is also diverted, thereby reducing the amount of air intake by the first air intake port 201 and the air intake by the second air intake port 202 converging, and also reducing the amount of frost formation.

[0299] The second internal recess 2124 extends along the second side of the partition member 210 toward the third side by a second predetermined width L3 and a second predetermined length L4, which is shorter than the length of the evaporator 230 in the first cavity 282, the length of the evaporator 230 being the length along the second side toward the third side. The second and third sides may refer to the above description. The length of the second internal recess 2124 is shorter than the length of the evaporator 230, preventing the air in the first internal recess 2121 from flowing directly to the exhaust port and ensuring that the air in the first internal recess 2121 exchanges heat with the evaporator 230 before being discharged through the exhaust port.

[0300] The second internal recess 2124 is configured to have a second ceiling surface 2126 and a second guide surface 2125 connected to the second ceiling surface 2126, and the second guide surface 2125 is inclined downward in a direction away from the second ceiling surface 2126, and the second guide surface 2125 guides the wind downward by the slope of the second guide surface 2125 toward the side where the exhaust port is located, thereby allowing the wind to flow sufficiently to the evaporator 230.

[0301] In some cases, the first inner recess 2121 and the second inner recess 2124 can be used in combination, that is, the partition plate member 210 has the first inner recess 2121 and the second inner recess 2124 at the same time. In this case, the second inner recess 2124 and the first inner recess 2121 are separated by the third wall plate 215, and the recessed depths of the first inner recess 2121 and the second inner recess 2124 are the same, which makes the structure simple and easy to process.

[0302] When the partition member 210 is provided with both the first inner recess 2121 and the second inner recess 2124, the first predetermined length L2 is greater than or equal to the second predetermined length L4, and the first inner recess 2121 sufficiently guides the air taken in by the first air intake port 201 toward the exhaust port, and the second inner recess 2124 guides the air taken in by the second air intake port 202 toward the exhaust port, thereby ensuring the heat exchange effect between the wind and the evaporator 230.

[0303] The wind in the second inner recess 2124 may include the wind obtained after the intake air from the first intake port 201 and the intake air from the second intake port 202 join and mix.

[0304] The evaporator 230 includes a heat exchange tube 233 and a heat sink 234 connected to the heat exchange tube 233, and the heat sink 234 extends along the side where the second air intake 202 is located to the side where the air exhaust is located, and the heat sink 234 can guide the air to flow from the side where the air intake is located to the side where the air exhaust is located.

[0305] The heat sink 234 is configured with a protrusion that extends into the second internal recess 2124 to ensure that the air within the second internal recess 2124 exchanges heat sufficiently with the heat sink 234.

[0306] As shown in Figure 29, the partition plate member 210 is configured with a third internal recess 2127, one side of which faces the first air intake 201 and the other side of which faces the second air intake 202, the first air intake 201 and the second air intake 202 being located on adjacent sides such that the third internal recess 2127 is located in the intersection area corresponding to the first air intake 201 and the second air intake 202, and the third internal recess 2127 increases the space in the intersection area of ​​the intakes of the first air intake 201 and the second air intake 202, increases the frost storage space, extends the air intake time at the end where the air intake is located, and reduces the number of defrosting operations, thereby extending the defrosting cycle and saving power consumption for defrosting.

[0307] Here, the first air intake 201 and the second air intake 202 are located on adjacent sides, and as shown in Figure 5, the first air intake 201 is located on both the left and right sides of the air duct component 200 and is connected to the first section 410 via the return air member 430, and the second air intake 202 is located on the front side of the air duct component 200, and both the first air intake 201 and the second air intake 202 are located in positions near the front of the air duct component 200.

[0308] The first air intake port 201 and the second air intake port 202 may be located on opposite sides (not shown), for example, the first air intake port 201 is located on the left side of the air passage component 200, and the second air intake port 202 is located on the right side of the air passage component 200. In this case, the third internal recess 2127 can provide a larger joining space for the air intake by the first air intake port 201 and the air intake by the second air intake port 202. The first air intake port 201 and the second air intake port 202 may be located on opposite sides, and the distance between the first air intake port 201 and the second air intake port 202 may be increased, appropriately reducing the amount of air that crosses and exchanges heat.

[0309] The third internal recess 2127 extends along the side where the second air intake 202 is located to the side where the air exhaust is located by a third predetermined width L5 and a third predetermined length L6, the third predetermined length L6 being smaller than the length of the evaporator 230 in the first cavity 282, the length of the evaporator 230 being the length from the side where the second air intake 202 is located to the side where the air exhaust is located.

[0310] As shown in FIG. 29, the width direction of the third internal recess 2127 is perpendicular to the direction from the second intake port 202 toward the exhaust port, the third predetermined width L5 is the size in this direction, and the third predetermined length L6 is the length in the direction from the second intake port 202 toward the exhaust port.

[0311] The third internal recess 2127 is configured to have a third ceiling surface 2128 and a third guide surface 2129 connected to the third ceiling surface 2128, and the third guide surface 2129 is inclined downward in a direction away from the third ceiling surface 2128, and the third guide surface 2129 faces the side where the exhaust port is located. The third guide surface 2129 guides the wind in the third internal recess 2127 toward the evaporator 230, so that the wind in this portion is discharged after sufficient heat exchange.

[0312] Based on the above embodiments of each component such as the drainage plate 100, fan cover 240, fan 270, air duct member 220, defrosting heating structure, and partition plate member 210, the following structure of the air duct component 200 is proposed, however, the air duct component 200 is not limited to the following structure.

[0313] As shown in FIGS. 1 to 13, the air passage component 200 includes a partition plate member 210 and an air passage member 220. The partition plate member 210 and the air passage member 220 form a first cavity 282, an air intake port, and an exhaust port, which are connected to each other. The air intake port is divided into a first air intake port 201 and a second air intake port 202. A drain plate 100 is provided in the first cavity 282. The drain plate 100 is disposed below the ceiling surface of the drain plate 100. The drainage plate 100 is configured to have a water guide portion that is recessed in the direction of extension, and the water guide portion extends to the edge of the drainage plate 100 on both sides of the specified surface so that the edge of the drainage plate 100 forms an opening 170, and the opening 170 faces the side where the first air intake port 201 is located, so that some of the air intake by the first air intake port 201 is configured to flow into the first cavity 282 through the opening 170 along the extension direction of the water guide portion. A portion of the air taken in by the first air intake port 201 is introduced into the first cavity 282 through the opening 170 along the extension direction of the water guide section, which allows a portion of the air taken in by the first air intake port 201 to be diverted, reducing the amount of air that crosses and comes into contact with the air taken in by the second air intake port 202.Furthermore, the amount of frost that condenses when the air taken in by the first air intake port 201 and the air taken in by the second air intake port 202 cross and come into contact with each other can be reduced, thereby reducing the number of defrosting operations, extending the defrosting cycle, reducing the power consumption required for defrosting, and reducing the power consumption of the refrigeration equipment.

[0314] The water conducting section may be at least one of the structures shown in FIGS. 1 to 13, that is, the water conducting section may be at least one of the second water conducting section 130 and the third water conducting section 140.

[0315] As can be seen, the air passage component 200 further includes a first drainage member 260 located on the first side, the first drainage member 260 communicating with the opening 170 of the drainage plate 100, and the first drainage member 260 having a drainage port. The first drainage member 260 simultaneously has the functions of drainage and intake.

[0316] As can be seen, air duct component 200 further includes fan cover 240, which defines second cavity 281, fan 270 is provided within second cavity 281, a rotation axis of fan 270 forms a first included angle α1 with the vertical direction, and fan cover 240 is provided with ventilation opening 244, with the inlet of fan 270 facing ventilation opening 244. Fan 270 is placed horizontally within fan cover 240, which allows the height of fan 270 to be reduced, and further reduces the height of air duct component 200, allowing a drawer to be attached below air duct component 200.

[0317] As can be seen, the evaporator 230 is provided in the first cavity 282, the drainage plate 100 is located below the evaporator 230, the angle between the evaporator 230 and the horizontal direction is equal to or less than a predetermined angle, or the evaporator 230 is parallel to the horizontal direction, the evaporator 230 is placed horizontally, and the angle at which it is inclined downward is equal to or less than 7°, or it may be horizontal, so that the vertical space occupied by the evaporator 230 is reduced, and the height of the air duct component 200 is also reduced accordingly, contributing to an increase in the space of the refrigeration equipment.

[0318] Components such as the partition plate member 210, the air passage member 220, the first drainage member 260, the fan 270, the fan cover 240, the drainage plate 100, and the evaporator 230 can all adopt the structures according to the above embodiments, and will not be described further here.

[0319] As shown in FIGS. 10 to 25 , air passage component 200 includes partition plate member 210, air passage member 220, evaporator 230, and drainage plate 100. Partition plate member 210 and air passage member 220 define first cavity 282, first air intake port 201, second air intake port 202, and air exhaust port, which are in communication with each other. First air intake port 201 is located on a first side of first cavity 282, and second air intake port 202 is located on a second side of first cavity 282, with the first side and the second side being adjacent to each other. Evaporator 230 is provided in first cavity 282, and drainage plate 100. 0 is located in the first cavity 282, and the drainage plate 100 is located below the evaporator 230 and is configured to have a water-conducting section that is recessed downward relative to the ceiling surface of the drainage plate 100, and a drainage section 110, and the drainage section 110 has an outlet 114 configured and communicates with the water-conducting section, the extension direction of the drainage section 110 and the extension direction of the water-conducting section form a fifth included angle, and the end of the water-conducting section forms an opening 170, and the opening 170 faces the first air intake port 201, so that the wind from the first air intake port 201 flows into the first cavity 282 along the extension direction of the water-conducting section. The water guide section plays a role in guiding the air taken in by the first air intake port 201, so that a portion of the air taken in by the first air intake port 201 flows along the water guide section into the first cavity 282, reducing the amount of air that crosses and comes into contact with the air taken in by the first air intake port 201 and the second air intake port 202, reducing the amount of frost that condenses due to the contact of air of different temperatures, and further extending the time between defrosting operations, reducing the number of defrosting operations, and saving power consumption during defrosting, thereby playing a role in saving power and energy.

[0320] In this case, the structure of the water guide section may be a third water guide section 140.

[0321] As will be appreciated, the outlet 114 and the exhaust port of the drain plate 100 are located on the same side of the first cavity 282, and the heat of the defrost water flowing to the outlet 114 of the drain plate 100 can provide defrosting for the fan 270 on the same side.

[0322] As can be seen, the ceiling surface of the drainage plate 100 and the bottom surface of the evaporator 230 are both inclined obliquely downward at a predetermined angle, or the ceiling surface of the drainage plate 100 and the bottom surface of the evaporator 230 are both parallel to the horizontal plane. The evaporator 230 is placed horizontally, and the downward inclination angle may be 7° or less, or it may be horizontal, which reduces the vertical space occupied by the evaporator 230 and accordingly reduces the height of the air-duct component 200, contributing to an increase in the space of the refrigeration equipment.

[0323] Air passage component 200 further includes a first drainage member 260 located on the first side, which surrounds opening 170 and communicates with opening 170, and which is configured to have a first drainage port 262. First drainage member 260 may be provided within a foam layer of cabinet 400 to increase the space of the compartment.

[0324] Air-duct component 200 further includes fan cover 240, which defines second cavity 281. Fan 270 is provided within second cavity 281, and a rotation axis of fan 270 forms a first included angle α1 with the vertical direction. Fan cover 240 is provided with ventilation opening 244, and the inlet of fan 270 faces ventilation opening 244. Fan 270 is placed horizontally within fan cover 240, which reduces the height of fan 270 and further reduces the height of air-duct component 200 as a whole.

[0325] Components such as the partition plate member 210, the air passage member 220, the first drainage member 260, the fan 270, the fan cover 240, the drainage plate 100, and the evaporator 230 can all adopt the structures according to the above embodiments, and will not be described further here.

[0327] In this case, the water guide portion may be at least one of the second water guide portion 130 and the third water guide portion 140.

[0328] The angle between the evaporator 230 and the horizontal direction is a predetermined angle or less, or the evaporator 230 is installed along the horizontal direction. The evaporator 230 is placed horizontally, and the angle at which it is tilted downward is 7° or less, or it may be horizontal, so that the space in the height direction occupied by the evaporator 230 is reduced, and the height of the air-duct component 200 is also reduced accordingly, contributing to an increase in the space of the refrigeration equipment.

[0329] The airway component 200 further includes a fan 270 located on one side of the first cavity 282, with the outlet 114 of the drainage plate 100 facing the side on which the fan 270 is located. The outlet 114 of the drainage plate 100 and the inlet of the fan 270 are offset to prevent water from flowing into the fan 270.

[0330] The second air intake 202 is located on the front side of the air duct component 200 and is connected to the second compartment 420, and the first air intake 201 is located on at least one of the left and right sides of the air duct component 200 and is close to the front end, and the first air intake 201 and the first compartment 410 are connected, thereby returning air through the front end of the air duct component 200.

The openings 170 face the first side, and the fan 270 is located on the third side of the first cavity 282. In other words, the drain positions of the fan 270 and the drain plate 100 are located on different sides, which reduces the space occupied by the side where the fan 270 is located and further increases the compartment space within the refrigeration appliance, thereby providing a large-capacity refrigeration appliance.

[0333] The air passage component 200 further includes a first drainage member 260 located on the first side, the drainage passage of the first drainage member 260 communicating with the opening 170, and the first drainage member 260 having a drainage port.

[0334] The included angle between the evaporator 230 and the horizontal direction is equal to or less than a predetermined angle, the evaporator 230 is placed horizontally, and the downward inclination angle thereof may be equal to or less than 7°, so that the vertical space occupied by the evaporator 230 is reduced, and the height of the air duct component 200 is accordingly reduced, thereby contributing to an increase in the space of the refrigeration equipment.

The second drain member 290 is located on the third side and has a water guide passage communicating with the outlet 114. The first drain member 260 and the second drain member 290 cooperate to allow the air passage component 200 to drain water from different sides, increasing the number of drainage paths and contributing to the defrost water received by the drain plate 100 being discharged in multiple directions, thereby improving defrosting and drainage efficiency.

[0348] The included angle between the evaporator 230 and the horizontal direction is equal to or less than a predetermined angle, the evaporator 230 is placed horizontally, and the downward inclination angle thereof may be equal to or less than 7°, so that the vertical space occupied by the evaporator 230 is reduced, and the height of the air duct component 200 is accordingly reduced, thereby contributing to an increase in the space of the refrigeration equipment.

[0349] The air passage member 220 and the partition plate member 210 form an air intake port and an air supply port that communicate with the first cavity 282, and the drainage section 110 extends in the direction from the air intake port to the air supply port, thereby allowing water at the outlet 114 of the drainage plate 100 to be discharged through the water guide passage of the fan cover 240.

The dividing section plays a role of dividing a part of the air taken in by the first air intake port 201, and further reduces the amount of air that joins the air taken in by the first air intake port 201 and the air taken in by the second air intake port 202, reduces frost caused by temperature differences, extends the time interval between two defrosting operations, and reduces the power consumption for defrosting.

[0353] Here, the structures of the flow dividing sections can be referred to those shown in FIGS.

[0354] The diversion portion is a first internal recess 2121 formed in the partition member 210, which is recessed toward the inside of the partition member 210 and is configured to guide a portion of the air intake by the first air intake port 201 so that it is diverted into the first internal recess 2121, and the first air intake port 201 is located on at least one of the left and right sides of the first cavity 282.

Specific embodiments and effects of the ventilation section 23421 may refer to the embodiments of the evaporator 230 described above, and will not be further described here.

[0356] The included angle between the evaporator 230 and the horizontal direction is equal to or less than a predetermined angle, the evaporator 230 is placed horizontally, and the downward inclination angle thereof may be equal to or less than 7°, so that the vertical space occupied by the evaporator 230 is reduced, and the height of the air duct component 200 is accordingly reduced, thereby contributing to an increase in the space of the refrigeration equipment.

[0357] Components such as the partition plate member 210, air passage member 220, first drainage member 260, second drainage member 290, fan 270, fan cover 240, drainage plate 100, and evaporator 230 can all adopt the structure according to the above embodiment, and will not be described further here.

[0358] As shown in FIGS. 1 to 25, air passage component 200 includes partition plate member 210, air passage member 220, evaporator 230, and drainage plate 100. Air passage member 220, which is located below partition plate member 210, and partition plate member 210 form a first cavity 282, an air intake port, and an air exhaust port, which are in communication with each other. Evaporator 230 is provided in first cavity 282, and the included angle between evaporator 230 and the horizontal direction is a predetermined The angle is less than 1 / 4, the drainage plate 100 is provided in the first cavity 282, the drainage plate 100 is located below the evaporator 230, the drainage plate 100 is configured to have an outlet 114 and a water-conducting portion recessed relative to the ceiling surface of the drainage plate 100, the water-conducting portion is connected to the outlet 114, the extension direction of the water-conducting portion and the direction from the intake port to the exhaust port form a fourth included angle, and the heating material 160 is provided on the surface of the drainage plate 100. The evaporator 230 is placed horizontally within the air-duct component 200, and the angle at which the evaporator 230 is tilted downward relative to the horizontal is controlled to within a predetermined angle, thereby reducing the height occupied by the evaporator 230. The evaporator 230 allows the height of the air-duct component 200 to be reduced. The drainage plate 100 is provided with a water-conducting section, which meets the demand for drainage and also the demand for air heat exchange, ensuring that the air in the first cavity 282 fully exchanges heat with the evaporator 230 before being discharged.

[0362] When the air passage component 200 according to the above embodiment is applied to a box liner and a refrigeration appliance, the box liner and the refrigeration appliance have the above-mentioned beneficial effects.

[0363] The structure of the box liner will be described below with reference to the above air duct components.

[0364] The box liner includes a box liner body 300 and an air passage component 200 provided in the box liner body 300, and the air passage component 200 divides the space within the box liner body 300 into a first compartment 410 and a second compartment 420.

[0365] As shown in Figures 39 to 41, a first passage 312 is provided in the box liner body 300, a cavity 216 is formed inside the partition member 210, and a second passage 218 is provided on the side edge of the partition member 210, with the first passage 312 and the second passage 218 corresponding one-to-one, and the cavity 216, the second passage 218, and the first passage 312 communicating with each other.

[0366] Here, the second passage 218 may be provided on the side of the second plate 212 or on the side of the first plate 211.

[0367] By providing a first passage 312 in the box liner body 300 and a second passage 218 on the side of the partition member 210, after the partition member 210 is loaded into the box liner body 300, the first passage 312 and the second passage 218 cooperate to form a urethane foam sealant passage for the urethane foam sealant to enter the cavity 216, so that the partition member 210 can be foamed together with the box liner body 300. Before foaming, components such as the evaporator 230, air passage member 220, and drainage plate 100 can be pre-assembled to the partition member 210 to form the air passage component 200, which can then be loaded into the box liner body 300 and foamed together, thereby realizing a modularized mounting method. Compared with the mounting methods in the related art, this effectively simplifies the mounting steps, shortens the mounting time, and improves production efficiency.

[0368] When the box liner is applied to a refrigeration appliance, the cabinet of the refrigeration appliance includes a box liner main body 300, which is configured with a first passage 312, a cavity 216 formed inside the partition member, and a second passage 218 provided on the side of the partition member, which communicates with the second passage 218, the cavity 216, and the first passage 312, thereby forming a foam space, realizing integral foam molding of the air duct component and the box liner main body 300, and ensuring sealing performance at the connection points of the air duct component 200.

[0369] The refrigeration equipment cabinet 400 includes a housing provided outside the box liner body 300, and a foam compartment is formed between the housing and the box liner body 300. The box liner body is configured with a first passage 312, and a cavity 216 is formed inside the partition plate member 210, and a second passage 218 is provided on the side of the partition plate member. The foam compartment, the second passage 218, the cavity 216, and the first passage 312 are connected to each other, thereby forming a foam space and realizing integrated foam molding of the air duct component and the cabinet, simplifying the processing process.

[0370] In an embodiment of the present disclosure, the partition member 210 is configured to have a recess 217 communicating with the cavity 216, the recess 217 communicating with the second passage 218, the recess 217 being provided around the cavity 216, the urethane foam sealant entering the recess 217 through the second passage 218 and then entering the gap from a different direction through the recess 217, thereby allowing the urethane foam sealant to quickly fill the entire gap and form the first insulating layer 213, shortening the foaming time and improving the foaming efficiency.

[0371] The partition plate member 210 includes a first plate 211 and a second plate 212. The edge of the second plate 212 is recessed downward to form a recess 217 communicating with the cavity 216. The recess 217 is U-shaped, and a through-hole, i.e., a second passage 218, communicating with the recess 217 is provided on the side of the second plate 212. A groove is provided on the bottom of the second plate 212, and the gap between the center of the second plate 212 and the first plate 211 is relatively small, so that the speed at which the urethane foam sealant enters the gap during the foaming process is relatively slow. By providing a recess 217 on the edge of the second plate 212, the urethane foam sealant first enters the recess 217 through the second passage 218, and then enters the gap from a different direction through the recess 217, allowing the urethane foam sealant to quickly fill the entire gap and form the first insulating layer 213, shortening the foaming time and improving the foaming efficiency.

[0372] 41, a slot 311 is provided in the box liner main body 300, the side edge of the partition plate member 210 is engaged and connected to the slot 311, and the first passage 312 is a through-hole provided in the slot 311. During installation, the side edge of the partition plate member 210 is engaged and connected to the slot 311, and then the partition plate member 210 is foamed together with the box liner main body 300, thereby completing the installation of the air passage component 200, which effectively simplifies the installation steps, shortens the installation time, and improves operating efficiency.

[0373] Here, the second passage 218 and the first passage 312 are both in the form of through holes, and may of course also be in the form of slits. The specific structural form of the mounting structure is not limited to the slot 311, and snap fasteners or other connecting structures may also be adopted.

[0374] 41 , the box liner of the refrigeration appliance further includes a return air member 430, which is provided on the inner wall of the first compartment 410 and communicates with the first air intake port 201. When the fan 270 is started, the air in the first compartment 410 enters the first cavity 282 through the return air member 430 to exchange heat with the evaporator 230, whereby the temperature of the air is reduced and the cooled air further enters the first compartment 410 and the second compartment 420 through the first exhaust port 203 and the second exhaust port 204, respectively.

[0375] By providing the return air member 430 on the inner wall of the first compartment 410, maintenance of the return air member 430 is facilitated, the impact of the foaming process on the return air member 430 is avoided, the assembly steps of the refrigeration equipment are simplified, and production efficiency is improved. Furthermore, because the return air member 430 is located within the first compartment 410, the space between the box liner body 300 and the housing is reduced, the storage space of the box liner body 300 is increased, and the capacity of the box liner body 300 is effectively improved.

[0376] As shown in FIG. 41, the return air member 430 further includes a return air pipe 431, and the inner wall of the first compartment 410 is provided with a positioning groove 313, the return air pipe 431 is fitted into the corresponding positioning groove 313, and the air outlet of the return air pipe 431 is connected to the corresponding first air intake port 201.

[0377] By fitting the return air pipe 431 into the positioning groove 313, the space occupied by the return air member 430 is reduced, which contributes to improving the storage space of the refrigeration equipment and provides a refrigeration equipment with a large capacity.

[0378] The air outlet of the return air pipe 431 is detachably connected to the first air intake 201, and by detachably connecting the air outlet of the return air pipe 431 to the first air intake 201, the shape and size of the first air intake 201 match the shape and size of the air outlet of the return air member 430. The first air intake 201 may be provided on a side edge of the first plate 211 or on a side edge of the second plate 212.

[0379] As shown in Figure 41, the return air pipe 431 is arranged in the vertical direction, and a main return air port 432 that communicates with the air outlet of the return air pipe 431 is formed at the upper end of the return air pipe 431, and an auxiliary return air port 433 that communicates with the air outlet of the return air pipe 431 is formed on one side of the return air pipe 431.

[0380] The return air member 430 includes two return air pipes 431, and the left and right walls of the first section 410 are each provided with a positioning groove 313 extending vertically. The positioning grooves 313 are located on the left and right walls, respectively, closer to the door body, and the two return air pipes 431 are fitted into the corresponding positioning grooves 313.

[0381] Since the temperature of the cold air near the door body is the highest, by providing the return air member 430 on the side of the inner wall closest to the door body, the return air member 430 can return the cold air near the door body into the first cavity 282 and exchange heat, effectively preventing the cold air coming out of the exhaust port from directly entering the return air member 430, improving the refrigeration efficiency of the refrigeration equipment.

[0382] The following provides an embodiment of a refrigeration appliance with reference to the above airway components.

[0383] The refrigeration equipment includes a cabinet and an air duct component, the air duct component being located within the cabinet and separating a first compartment from a second compartment, the air duct component including a partition member, an air duct member, an evaporator, and a drainage plate, the partition member and the air duct member defining a first cavity, a first intake port, a second intake port, a first exhaust port, and a second exhaust port, the partition member and the air duct member being configured to communicate with the first intake port, the first cavity, the first exhaust port, and the first compartment, and the second intake port, the first cavity, the second exhaust port, and the second compartment, and the evaporator and the drainage plate being provided within the first cavity, the air duct member supporting the drainage plate being located below the evaporator, and the included angle between the evaporator and a horizontal plane being equal to or less than a predetermined angle, or the evaporator being parallel to the horizontal plane. The evaporator is placed horizontally within the air duct component, and the angle at which the evaporator is tilted downward relative to the horizontal direction can be controlled within a predetermined angle, or the evaporator can be installed horizontally, which can reduce the height space occupied by the evaporator, and further reduce the height of the entire air duct component, thereby reducing the space within the cabinet occupied by the air duct component, and the storage space within the cabinet can be correspondingly increased, thereby providing a large-capacity refrigeration equipment.

[0384] In some cases, the first compartment is located above the second compartment, the first compartment being a refrigerated compartment and the second compartment being a freezer compartment.
