[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 embodiment, 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 partitioned by the air duct component 200 into a first compartment 410 and a second compartment 420 that are independent of each other.

[0033] The air passage component 200 can serve to separate the compartments and can also serve to circulate air. In order to ensure the independence of the first compartment 410 and the second compartment 420, it is necessary to ensure that the attachment points of the air passage component 200 and the box liner main body 300 are sealed to prevent gas from mixing between the first compartment 410 and the 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 section 410 and a second section 420, or the air duct component 200 may partition a partial space within the box liner body 300 into two parts, a first section 410 and a second section 420.

[0035] The air passage component 200 blows air to the first compartment 410 and the second compartment 420 independently, and the functions of the first compartment 410 and the second compartment 420 may be the same or different. When the functions of the first compartment 410 and the second compartment 420 are different, that is, when the environmental temperatures in the first compartment 410 and the second compartment 420 are different, the first compartment 410 may be a refrigerated compartment and the second compartment 420 may be a freezer compartment, and the frequency at which the air passage component 200 blows air to the refrigerated compartment is lower than the frequency at which the air passage component 200 blows air to the freezer compartment. When the functions of the first compartment 410 and the second compartment 420 are the same, for example, when both are refrigerated compartments, the environmental temperatures of the two refrigerated compartments may be the same or different. In this case, the frequency at which the air passage component 200 blows air to the two refrigerated compartments may be the same or different, and can be specifically 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 other functional compartments, and can be specifically set as needed.

[0036] When the cabinet 400 is connected to a door body and the door body is in a position to seal 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 to open the cabinet 400, items can be inserted and removed from 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 necessary.

[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, the partition plate member 210 is located above the air passage member 220, 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, 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 collectively define an air intake port, a first cavity 282, and an exhaust port, which are in communication with each other, so that air that has entered the air passage component 200 exchanges heat and is then exhausted.

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

[0040] The air intake of the air duct component 200 is divided into a first air intake 201 and a second air intake 202, and the air exhaust of the air duct component 200 is divided into a first air exhaust 203 and a second air exhaust 204, the first air intake 201, the first cavity 282, the first air exhaust 203 and the first section 410 are connected to form a first circulation path, the second air intake 202, the first cavity 282, the second air exhaust 204 and the second section 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 section 410 and the second section 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, i.e., 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 section 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 section 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-path component 200, the first exhaust 203 and the second exhaust 204 are also near the same end of the air-path component 200, and the air intake and exhaust are generally located at opposite ends, and as described above, the air intake is near the front end and the exhaust is near the rear end, but are not limited to the above-mentioned positions, and both air intakes may be close to the left end or the right end, and the positions of the air intake and exhaust are flexible and can be selected specifically 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 provided on different sides of the air-path component 200. In this case, when 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 section 410 and the second section 420 have different environmental temperatures), 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 location of the first intake port 201 and the second intake port 202 on different sides of the air-path 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] Hereinafter, as shown in Figures 1 to 16 and 20 to 25, an embodiment of the drainage plate 100 is provided, and the structure of the drainage plate 100 will be described taking as an example the drainage plate 100 being attached within the above-mentioned air passage component 200. However, the drainage plate 100 is not limited to being attached within the above-mentioned air passage component 200, and the drainage plate 100 described below may be attached to another structure 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 downwardly relative to a 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 a portion 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] Here, the function of the first air intake 201 is not limited, and it may communicate with the refrigerated compartment and the water guide part guides the refrigerated air, or the water guide part may communicate with the freezing compartment and guide the freezing air. By providing the water guide part, the drain plate is designed in an inverted V-shaped structure, and some of the refrigerated return air enters the evaporator 230 through the V-shaped structure space, thereby solving the problem of condensation of the return air of the refrigerator, reducing the contact between the refrigerated return air and the frozen return air, reducing the condensation caused by the condensation and mixing with the frozen return air, distributing the frost more uniformly in the evaporator, and reducing the blockage of the frozen return air caused by the frost.

[0048] A portion of the air intake through first air intake port 201 passes through opening 170 and is introduced into first cavity 282 along the extension direction of the water-guiding section, thereby diverting a portion of the air intake through first air intake port 201, reducing the amount of air that merges with the air intake through second air intake port 202, and further reducing frost that condenses when the air intake through first air intake port 201 comes into contact with the air intake through second air intake port 202, 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-guiding section is recessed downward toward the ceiling surface of the drainage plate 100, a groove is formed in the drainage plate 100, and a portion of the air taken in by the first air intake port 201 flows along the groove into the first cavity 282, with the water-guiding section playing a role in guiding the wind inside.

[0050] Here, the predetermined surface and the extending direction of the water guiding portion form an included angle, the predetermined surface extends along the direction from the intake port to the exhaust port, and for example, when the intake port is located at the front end of the air passage component 200 and the exhaust port is located at the rear end of the air passage 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 necessary.

[0051] In some cases, the specified plane may be a symmetrical plane of the drainage plate 100, and the water-guiding 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 symmetrical plane, 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 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 opening 170 of the drain plate 100 can serve as a guide for a part of the air drawn in by the first air inlet 201, and the opening 170 of the drain plate 100 can also serve as a drain.

[0054] When the opening 170 of the drain 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 drain plate 100 is not limited.

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

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

[0057] As can be seen, the bottom of the second water guiding section 130 is inclined along a first predetermined direction toward the opening 170, and the first predetermined direction and the ceiling surface of the drainage plate 100 form a first predetermined angle. In other words, the bottom surface of the second water guiding 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 obliquely 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-wise size of the drainage plate 100, the first specified included angle may be an included angle of 7° or less, so that both the drainage effect and the wind guidance effect can be met, and the height-wise size of the air duct component 200 can be reduced, and the height-wise 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 can also make the height of the drainage plate 100 small enough to realize 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-guiding portion does not have to change (not shown), and the recessed depth of the second water-guiding portion remains consistent and can also fulfill the role of guiding air and draining water.

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

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

[0065] As shown in Figures 5 to 7, a plurality of second water-guiding sections 130 are provided on each side of a specified surface of the drainage plate 100, and the plurality of second water-guiding sections 130 are arranged in parallel, and a plurality of openings 170 are formed on both sides of the drainage plate 100 so that a portion 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 position, the width of the second water guiding section 130 is gradually narrowed in the direction of the opening 170 so that the water received in the second water guiding section 130 is gathered in the direction of the opening 170 .

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

[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 above-mentioned drainage plate 100 and the evaporator 230 are both installed in the first cavity 282 of the air passage component 200, the wind enters the first cavity 282 from the intake port of the air passage component 200 and flows in the direction of the exhaust port, and the wind 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 wind flows between the drainage plate 100 and the evaporator 230, the water guide part and the air blowing direction form a fourth included angle, which can prevent the wind from flowing directly from the water guide part to the exhaust port, thereby extending the time that the wind stays in the first cavity 282, and the wind comes into sufficient contact with the evaporator 230 to exchange heat, and the wind after heat exchange is further discharged from the exhaust port, which contributes to improving the heat exchange efficiency.

[0070] Here, the air blowing direction is the direction from the air intake port to the air exhaust port, and in some cases, the air intake port and the air exhaust port are provided one by one, and have a one-to-one corresponding relationship, forming one air blowing direction, and in some cases, at least one of the air intake port or the air exhaust port is provided in a plurality of locations, and a plurality of air blowing directions can be formed. The extension direction of the water guide portion and at least one air blowing direction form an included angle, and the heat exchange efficiency of the wind can be ensured in one direction, and of course, when the extension direction of the water guide portion and all the air blowing directions form an included angle, it can be ensured that the wind in the plurality of flow paths can effectively exchange heat, and the heat exchange efficiency can be ensured. Here, the air intake port is generally provided at one end near the front of the air passage component 200, and the air exhaust port is generally provided at one end near the rear of the air passage component 200, and the air blowing direction may be from front to rear.

[0071] When 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 path component 200, the exhaust port is provided in the rear of the air path component 200, the communication path between the second air intake 202 and the exhaust port forms a first air supply direction, and the second air intake 202 corresponds to a position near the bottom of the evaporator 230, the wind flows from bottom to top and 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, that is, the extension direction of the water guide portion and the front-rear direction form an included angle. The first air intake 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 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. 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 both be understood as a fourth included angle, but the specific angle value may be the same or different.

[0073] The extension direction of the water guiding section may be a straight path or a curved path. When the extension path of the water guiding section is a straight path, the path from one end of the water guiding section away from the drainage section 110 to the other end of the water guiding section connected to the drainage section 110 is the extension path, and when the extension path of the water guiding section is a curved path, the water guiding section of the curved path may have headers connected to multiple drainage sections 110, and 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, and the shape of the curved path can be set as needed. The extension direction of one water guiding 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 specifically can be 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, the drainage section 110 is configured to have 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, 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 provided below the evaporator 230 and is used to receive defrost water generated when the frost on the surface of the evaporator 230 is exposed to heat. Some of the water falls into the water guide section and is introduced into the drain section 110 along the extension direction of the water guide section. Generally, a plurality of water guide sections are provided, and the water received by each water guide 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] Here, the difference between the fifth included angle and the fourth included angle is that in a drainage plate where a water guide section and a drainage section are both provided, the included angle between the extension direction of the water guide section and the air supply direction is the fifth included angle, and in a drainage plate where only a water guide section is provided, the included angle between the extension direction of the water guide 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 necessary and are not limited here.

[0077] The solid arrow above the drainage plate 100 in Fig. 23 indicates the extension direction of the water guide portion, the dashed arrow indicates the air supply direction, and the fifth included angle θ1 is indicated, and the fifth included angle is 90° in the figure. Note that both the water guide portion and the drainage portion 110 are recessed based on the ceiling surface of the drainage plate 100, and the ceiling surface may be a flat surface or a curved surface, and the ceiling surface may be a surface defined by a plurality of lines, or may be a surface defined by a plurality of surfaces. Correspondingly, the bottom of the water guide portion and the bottom of the drainage portion 110 form the bottom surface of the drainage plate 100, and the bottom surface may be a flat surface or a curved surface, and the bottom surface may be a surface defined by a plurality of lines, or may be a surface defined by a plurality of surfaces. The upper surface of the drainage plate 100 is all surfaces of the drainage plate 100 that face upward, with the ceiling surface being part of the upper surface, and the lower surface of the drainage plate 100 is all surfaces of the drainage plate 100 that face downward, with the bottom surface being part of the lower surface.

[0078] According to the drainage plate 100 of this embodiment, the water guiding section can cooperate with the drainage section 110 to drain the received water, thereby solving the drainage problem within the air duct component 200. Furthermore, by arranging the water guiding section so that the 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 wind 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-guiding 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 be called a third water-guiding section 140, and as shown in Figures 11 to 13, the drainage section 110 is configured with an outlet 114, and the third water-guiding section 140 is connected to the drainage section 110, and the defrost water received by the third water-guiding section 140 may be discharged from the opening 170 at the end of the drainage plate 100, or may be discharged from the outlet 114 of the drainage section 110, thereby realizing multi-directional drainage, a simple structure, and good drainage effect.

[0080] In this case, the evaporator 230 and the drainage plate 100 can be arranged horizontally, the discharge of defrost water can be completed, and the height of the air passage component 200 can be reduced. If the evaporator 230 and the drainage plate 100 are both arranged diagonally downward to drain water, the angle at which the evaporator 230 and the drainage plate 100 are inclined downward (the angle at which the evaporator 230 and the drainage plate 100 are inclined downward may be 7° or less) can be reduced, and the size of the air passage component 200 in the height direction can be reduced, thereby 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, 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 drainage plate 100.

[0083] Along the extension direction of the drainage section 110, a plurality of third water-guiding sections 140 are arranged in parallel on both sides of the drainage section 110, and the plurality of third water-guiding sections 140 are distributed below the evaporator 230, which makes it easy to receive defrost water at multiple positions below the evaporator 230, contributing 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 form an included angle. When the area of ​​the drainage plate 100 is constant, 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 being collected in the drainage section 110, and can facilitate shortening the drainage time of the defrost water. When a plurality of drainage sections 110 are provided, the third water guide section 140 close to 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 within the drainage portion 110 to flow to the outlet 114 by 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 and the ceiling surface of the drainage plate 100 form a seventh included angle θ3. 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 has a good drainage effect, can avoid the problem of localized water puddle, and can allow the water to flow smoothly.

[0087] The fact that the ceiling surface of the drain plate 100 is horizontal may be understood as the second direction forming a seventh included angle θ3 with the horizontal plane. Along the ceiling surface of the drain plate 100, the drain portion 110 is gradually recessed downward 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 portion 110 may be an oblique line or a slope, and in some cases, the bottom of the drainage portion 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 diagonal or slope, for example, may be stepped, and still be able to meet drainage needs.

[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 height direction 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°, and since the area of ​​the drainage plate 100 occupied by the drainage portion 110 is relatively small, and the angle at which the drainage portion 110 inclines 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 the 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 guiding 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 guiding section 140 is relatively large, the fourth flow guiding surface 141 can guide the water backward so that a portion 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 concave depth of the water guide portion gradually increases toward the drainage portion 110, and in this case, the water guide portion may be referred to as the first water guide portion 120. The first water guide portion 120 gradually increases in depth toward the drainage portion 110 so that water flows into the drainage portion 110 by the action of gravity and is discharged from the outlet 114 of the drainage portion 110.

[0096] As can be seen, the bottom of the first water guide 120 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. That is, the bottom of the first water guide 120 is inclined, and the water in the first water guide 120 gathers in the drainage section 110 along the inclined path (first direction), which has a good drainage effect, can avoid the problem of localized water puddles, and can allow the water to flow smoothly.

[0097] The fact that the ceiling surface of the drainage plate 100 is horizontally provided may be understood as the first direction forming a sixth included angle θ2 with the horizontal plane. Along the ceiling surface of the drainage plate 100, the first water guide section 120 is gradually recessed downward 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 included angle 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 guiding section 120 may be an oblique line or a slope, and in some cases, the bottom of the first water guiding 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 diagonal line or slope, for example, is stepped, it can still meet the water conducting demand.

[0100] As can be understood, the sixth included angle θ2 is 7° or less, and the small angle of the 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 to be achieved, and further reduces the heightwise 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 as 3°, which can meet the drainage demand of the drainage plate 100 and can make the height of the drainage plate 100 small enough to realize 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 guiding section 120 and the above-mentioned third water guiding section 140 is that the first water guiding section 120 is inclined toward the drainage section 110 in the drainage plate 100, and the third water guiding section 140 is inclined toward the end of the drainage plate 100, that is, the inclination direction is different, while other structures and parameters may be set to the same, for example, the inclination angle may be the same.

[0103] As can be understood, the bottom surfaces of the multiple water-guiding sections arranged in parallel on the same side of the drainage section 110 of the corresponding drainage plates 100 are flush with each other, thereby making the bottom surface of the drainage plate 100 more flat, and making the drainage plate 100 have a simple appearance and are easy to position and install.

[0104] Here, being arranged in parallel may be understood as a plurality of water guide sections arranged 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, when the drainage section 110 is provided at the end of the drainage plate 100, the water guide section is provided only on one side of the drainage section 110.

[0105] As can be understood, in order to achieve sufficient heat exchange, the extension direction of the water guide is perpendicular to the air blowing direction, which effectively extends the time that the wind 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 reduces the discharge of wind along the extension direction of the drainage section 110 as much as possible, 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 the water guide sections may be symmetrically provided 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 guiding section is perpendicular to the air blowing direction, and the wind entering the water guiding section is reduced as much as possible.

[0109] As will be understood, 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 the water in the water conducting section is collected in the drainage section 110 and pooling of water in the water conducting section is avoided.

[0110] As can be seen, as shown in Figures 20, 21 and 24, a plurality of water guide sections are provided on both sides of the drainage section 110, which are all parallel to each other, and the plurality of water guide sections guide water from different parts into the drainage section 110. It can be seen that by providing a plurality of water guide sections, both sides of the drainage section 110 are formed into a wavy structure, which reduces the area of ​​the ceiling surface of the drainage plate 100 as much as possible, reduces the pooling of water on the ceiling surface of the drainage plate 100, and allows the water received by the drainage plate 100 to be quickly discharged from 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 the two and more than two 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 is unchanged, the length of the water guide section can be shortened by increasing the number of drainage sections 110, and the water can 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, a first water-conducting region 123 located on the side of the first drainage section 111 and a second water-conducting region 124 located on the side of the second drainage section 112 are configured, and the recessed depth of the water-conducting section of the first water-conducting region 123 gradually increases toward the first drainage section 111, and the recessed depth of the water-conducting section of the second water-conducting region 124 gradually increases toward the second drainage section 112. In other words, at the abutment position between the first water conducting region 123 and the second water conducting region 124, the recessed depth of the water conducting section is at a minimum, which contributes to the first water conducting region 123 directing the water it receives to the first drainage section 111 and the second water conducting region 124 directing the water it receives to the second drainage section 112, thereby shortening the length of the water conducting 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 to avoid the inlet of the fan 270 as much as possible. A plurality of water-guiding sections, all parallel to each other, are provided on both sides of the drainage section 110, which contributes to shortening the water-guiding path of the water-guiding section and accelerating the discharge of water.

[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 provided at the rear end of the drainage plate 100, the water-guiding section extends in the left-right direction, and both the left and right sides of the drainage section 110 are formed into a wave-shaped structure. The installation of the wave-shaped plate is advantageous for collecting and discharging water. In this case, there is no need for the evaporator 230 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 is inclined and extends in the left-right direction, and the inclination angle of the water guide section does not affect the angle in the front-rear 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-rear direction, but from an overall perspective, the drain section 110 is provided at a local position on the drain plate 100, the area of ​​the drain plate 100 occupied by the drain section 110 is relatively small, and the inclination angle of the local position of the drain plate 100 is somewhat large, which has a relatively small impact on the storage space of the entire compartment, and the volume within the compartment can also be optimized.

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

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

[0118] At least one of the side surfaces on both sides of the first water guiding section 120 along its extension direction is provided as a first flow guiding surface 121. The shape of the vertical cross section of the first water guiding 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 guiding section 120 in its extension direction are first flow guiding surfaces 121, and both sides of the first water guiding section 120 can guide 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 opposing 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 be further 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 guiding surface 113. The cross-sectional shape of the drainage section 110 may be 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 guiding surfaces 113, and both sides of the drainage section 110 can guide flow.

[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 guiding surface 121 and the second flow guiding surface 113 may be flat or curved, and specifically may be selected according to need.

[0123] As will be understood, in the first predetermined cross section in the extension direction of the water conducting portion, the width of the water conducting portion gradually decreases toward the direction of the drainage portion 110. The water conducting portion is in a state of gradually converging toward the direction of the drainage portion 110, which may be understood to contribute to collecting water in the water conducting portion and allowing the water in the water conducting portion to enter the drainage portion 110.

[0124] The first predetermined cross section here is a cross section parallel to the ceiling surface of the drainage plate 100, and may be understood as a horizontal cross section in a state in which the drainage plate 100 is attached. The width of the water guiding section is understood as the distance between two side walls in the extension direction of the water guiding section, and may be understood as the distance between two first flow guiding surfaces 121, taking the first water guiding section 120 as an example. Gradually decreasing the width generally means continuously decreasing the width, but decreasing 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 conducting portions is collected toward the drainage portion 110, the amount of water is maximum at the position of the outlet 114 of the drainage portion 110, and the width of the drainage portion 110 increases, which can provide a larger drainage space and contribute to the 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 a horizontal cross section in a state in which the drainage plate 100 is attached. 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. The increase generally means a gradual increase, but it is not excluded that the increase may occur in stages.

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

[0128] 22, an edge of the drainage plate 100 is folded upward to form a flange 150, which surrounds the drainage plate 100 and is grooved 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 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 for limiting the position of the first heater 231 above the drainage plate 100, so that the fixing method of the first heater 231 is simple and the structure of the drainage plate 100 is simple.

[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 shape 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 inclined downward in the front-to-rear direction, which solves the problem that the internal volume of the compartment is lost when the evaporator 230 has an inclination angle, 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 internal volume of the compartment.

[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 vibration 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 in synchronization with the defrosting operation or may be appropriately delayed from the defrosting operation.

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

[0136] Hereinafter, based on the above-mentioned drainage plate 100, a drainage structure that connects the drainage plate 100 and a drain 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 in communication with 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 can be fully received, and further allowing the drainage water to be collected in the first drainage outlet 262.

[0140] As shown in Figures 6 and 7, the first drainage member 260 covers all of the openings 170 of the drainage plate 100 as much as possible, ensuring the sealing of the connection parts between the first drainage member 260, the air passage member 220, and the partition plate member 210, and preventing the occurrence of wind leakage and water leakage. As shown in Figures 5 and 7, some of the openings 170 do not correspond to the first drainage member 260 in order to indicate the positions of the openings 170, and 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 communicating 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 the occurrence of water leakage.

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

[0143] 13, the first drainage member 260 includes a first wall plate 264 and a second wall plate 265 arranged opposite to each other, the first wall plate 264 is configured with a through hole, and the second wall plate 265 is configured with a first air intake 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 the occurrence of leakage at the connection point.

[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 section 410 enters the first cavity 282 through the first air intake port 201.

[0145] As shown in FIG. 2 to FIG. 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, the fan 270 is provided in the second cavity 281, and the first side and the second side 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 side and the right side, 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 is different from the air blowing direction of the first cavity 282, which can reduce the water vapor carried by the wind, reduce the effect of drainage on the fan 270, and reduce 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 side and the right side.

[0146] As shown in Figures 5 to 8, the drain plate 100 includes a second water guide section 130, which is recessed with respect to the ceiling surface of the drain plate 100, and the extension direction of the second water guide section 130 and the air supply direction above the drain plate 100 form an included angle, and the recessed depth of the second water guide section 130 gradually increases along a predetermined surface toward the first side of the second cavity 281, and the second water guide section 130 forms an opening 170 toward the end of the first side of the second cavity 281, and the water received by the second water guide section 130 is discharged from the opening 170 along the extension direction of the water guide section, and the opening 170 is connected to the above-mentioned first drain member 260, so that the water is discharged from the first drain port 262. The structure of the drain plate 100 is simple and has a 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 have different paths through which they enter the first cavity 282, thereby reducing the contact of the two return airs and also reducing the amount of frost caused by the contact of the two return airs.

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

[0148] The drainage plate 100 includes a second water guide portion 130 extending from a predetermined position to the left and a second water guide portion 130 extending from a predetermined position to the right, and the drainage plate 100 has an opening 170 facing both the left and right sides, and the first drainage member 260 is provided on both the left and right sides of the air passage component 200, so that the structure is simple and the water guide effect is good. Here, the predetermined position may be a symmetrical plane of the drainage plate 100, or a vertical plane extending along the front-rear direction. The predetermined plane may be an end face of the above-mentioned drainage portion, and the predetermined planes of the second water guide portions extending to the left and right sides 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 the fan 270 is provided at the rear of the air passage component 200, the first drainage member 260 is provided at least one of the left and right sides of the air passage component 200, and the above drainage method may be understood as side drainage. Since the fan 270 is provided at the rear of the air passage component 200, in this case, the evaporator 230 and the fan 270 drain independently, the defrost water of the evaporator 230 is discharged from both the left and right sides through the first drainage member 260, and the defrost water flowing in the fan direction and the water condensed by encountering the fan 270 can be discharged through the structure below the fan 270, which may be the rear drainage structure described below, or may be another structure capable of discharging the water in the 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-path component 200 further includes a fan cover 240, the fan cover 240 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 within the fan cover 240, or the second drainage member 290 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 within the fan cover 240, the space within the fan cover 240 can be fully utilized, the height of the air-path 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 where the outlet 114 of the drainage plate 100 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 the water led out from the drainage plate 100, the water dripping from the first cover 241, and the water dripping from the fan 270, and lead out the defrost water of the first cavity 282, which contributes to simplifying the structure of the air passage component 200. In this case, the drainage plate 100 may adopt a structure having a drainage portion 110, and specifically, reference may be made to the embodiment of the drainage plate 100 described above. 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 constitutes a first water guide passage 2421 that communicates with the outlet 114 of the drainage plate 100, and includes a partition wall portion 2422 that protrudes upward along the surface of the second cover 242, the partition wall portion 2422 defining the first water guide passage 2421, and the fan 270 is located on the side of the partition wall portion 2422. The partition wall portion 2422 serves to separate the first water guide passage 2421 and the fan 270, and prevents water from flowing into the fan 270, thereby reducing the effect of water on the fan 270.

[0157] In the direction away from the outlet 114 of the drain plate 100, the first water guide passage 2421 is inclined downward so that the water in the first water guide passage 2421 is guided downward, and the structure is simple and the drainage effect is good. 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 part 2422 may be a plate-like structure or a block-like structure protruding above the second cover 242, and specifically may be selected as necessary. Of course, the partition part 2422 may be a part detachably connected to the second cover 242, for example, a plate structure inserted or engaged with the second cover 242, but the structure of the partition part 2422 is not limited thereto, and may be a structure capable of realizing other partition functions.

[0159] In addition, a partition plate 2427 is provided between the drain plate 100 and the second cover 242, and the partition plate 2427 communicates the drain plate 100 and the second cover 242 only through the outlet 114, and the other parts are 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, and the other parts are separated. The partition plate 2427 may be integrally formed with the second cover 242, or may be removably connected.

[0160] The second cover 242 and the drainage plate 100 may be two independent members, or the second cover 242 and the drainage 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 from 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 pillars 2426 are provided on the upper surface of the second cover 242. The fan mounting base 271 is fixed to the second mounting pillars 2426. By adjusting the height of the second mounting pillars 2426 at different positions, the inclination angle and direction of the fan 270 can be adjusted, and the structure is simple.

[0163] The upper surface of the second cover 242 slopes diagonally downward in the direction away from the drain plate 100, i.e., toward the third drain outlet 2423, thereby allowing the defrost water on the surface of the second cover 242 to 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 water collecting portion 2428 is gradually reduced in area toward the third drain outlet 2423 and communicates with 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 is gradually reduced 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 242 is collected and then discharged.

[0165] Based on the fact that the upper surface of the second cover 242 is inclined downward toward the direction of the third drainage port 2423, the water collection portion 2428 can also be inclined downward, which improves the drainage effect, but the water collection portion 2428 is not limited to being inclined downward, and it is not excluded that the water collection portion is installed horizontally.

[0166] The second cover 242 is provided with a heating member 226, which heats the second cover 242 to heat and defrost the fan cover 240 and the components therein, such as the fan 270. Here, the heating member 226 may be a heating film formed on the second cover 242, or the heating member 226 may be a heating plate located below the second cover 242, but the structural form of the heating member 226 is not limited thereto and may be other structures capable of realizing heating and defrosting.

[0167] Unlike the above-mentioned 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 communicating 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 via the fan cover 240, and the effect of water in the second water guide passage on components such as the fan 270 is reduced.

[0168] The shape of the second drainage member 290 may be a U-shaped structure with a flange, or the second drainage member 290 is provided as a structure integrally molded under the second cover 242, and the structure of the second drainage member 290 is diverse and can be selected as needed. If the drainage plate 100 is provided with a plurality of outlets 114, a plurality of second drainage members 290 can be provided under the fan cover 240, and the second water guide passage and the fan 270 do not interfere with each other. Under the air passage component 200, the local position corresponding to the second drainage member 290 protrudes downward, so that the height of the local position of the air passage component 200 is relatively large, which does not affect the height of other positions, and can also play a role in expanding 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, and the structure is simple and the drainage effect is good. 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 section through the second drain pipe 291.

[0170] Of course, the water guide passage (the first water guide passage 2421 or the 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 a wiring hole, whereby the electrical connection members of the air passage component 200 are wired through the wiring hole, realizing electrical connection, thus 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 first drainage member 260 and the 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 faces the outlet 114 and communicates 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 the third drain pipe 2231, and the water discharged from the outlet 114 of the drainage plate 100 flows along the water-conducting material 223 to the third drain 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 the ventilation opening 244 of the fan cover plate 243. The fan cover plate 243 is provided on the outside of the water-conducting material 223, and the fan cover plate 243 is fixed to the box liner body 300. Between the fan cover plate 243 and the rear wall of the box liner body 300, a cavity for mounting the fan 270 is surrounded and provided, and this cavity communicates with the first cavity 282 through the ventilation opening 244 opened in the fan cover plate 243. Alternatively, the cavity for mounting the fan 270, which is surrounded and provided by the fan cover plate 243 itself, communicates with the first cavity 282, and the fan cover plate 243 is fixed and attached to the box liner 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, the water guide material 223 may be understood as a part of the air passage member 220 or as an independent part from the air passage member 220, and specifically can be selected as necessary. The fan cover plate 243 is a mounting member for the fan 270, and the main function of the fan cover plate 243 is close to the main function of the fan cover 240, and the fan cover plate 243 or the fan cover 240 is provided in one air passage component 200, and the fan cover plate 243 is used in combination with the water guide material 223, and the fan cover 240 is used in combination with the second drainage member 290. When the air passage component 200 includes the fan cover 240, a ventilation hole 244 is opened in the fan cover 240, and thus the wind in the first cavity 282 is discharged by the fan 270 through the ventilation hole 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, whereby 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, the air passage component 200 further includes a fan 270, the rotation axis of the fan 270 forms a first included angle α1 with the vertical direction, the fan cover 240 has a ventilation port 244, the inlet of the fan 270 faces the ventilation port 244, the second cavity 281 communicates with the air supply area of ​​the first cavity 282 through the ventilation port 244, and the second cavity 281 communicates with the exhaust port of the air passage component 200. The wind in the first cavity 282 is sucked into the second cavity 281 by the fan 270 through the ventilation port 244 in the fan cover 240, and under the action of the fan 270, the wind in the second cavity 281 enters the first section 410 or the second section 420 through the exhaust port. In other words, the second cavity 281 and the first and second exhaust ports 203 and 204 can be adjusted to be on and off.

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

[0178] In this case, the ventilation opening 244 is offset from the drain outlet of the first cavity 282 to minimize the wind at the drain outlet being sucked out by the fan 270, extend the heat exchange time of the wind within the first cavity 282, and improve 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 understood, the air-duct component 200 further includes a fan cover 240, which includes a first cover 241 and a second cover 242, the first cover 241 being configured with 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, the first side of the flow directing surface 2411 and the second side of the flow directing surface 2411 being on opposing sides, and the fan cover 240 defining a second cavity 281, in which the fan 270 is provided. The first cover 241 serves to collect water vapor above the fan 270 and can direct the collected water droplets from the first side of the flow-directing surface 2411 to the second side of the flow-directing surface 2411. The provision of the first cover 241 can promote the collection and discharge of water vapor in the second cavity 281, reduce corrosion of the fan 270 caused by water vapor, and extend the life of the fan 270.

[0181] Here, the first included angle α1 is 7° or more, so that the water collected on the first side of the flow guiding surface 2411 flows to the second side along the gradient of its own surface, and the water is guided to the third drainage port 2423 along the air passage member 220 below the fan 270, and the water collected on the surface of the first cover 241 is prevented from dripping into the fan 270, and the water is prevented from falling onto the fan 270 as much as possible. Here, the first side of the flow guiding surface 2411 is higher than the second side of the flow guiding surface 2411, and the surface of the first cover 241 facing the fan 270 may be an inclined plane or curved surface. If the flow guiding surface 2411 is a plane, it contributes to simplifying the structure of the first cover 241 and makes it easier to process. In addition, the water collected on the surface of the fan 270 falls and is discharged by the action of gravity.

[0182] The first included angle α1 needs to 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 heightwise 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 direction size of the air-channel component 200 is smaller, but the water guide effect of the surface of the first cover 241 toward the fan 270 is not good, and the drainage effect is difficult to meet the demand. 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 are two cavities arranged in parallel in the front and rear, or the second cavity 281 is 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 can communicate with each other. For example, when the second cavity 281 is located behind the first cavity 282, the fan 270 is inclined forward at a first included angle α1 or backward at a first included angle α1. As shown in FIG. 14, the fan 270 is inclined forward at a first included angle α1, and as shown in FIG. 8, the fan 270 is inclined backward at a first included angle α1. That is, the upper end of the rotation axis of the fan 270 is inclined forward with respect to the vertical direction to form a first included angle α1, or is inclined backward with respect to the vertical direction to form a first included angle α1.

[0185] Here, the fan 270 is gradually inclined upward from the front to the back, that is, the inlet of the fan 270 faces the air blowing direction of the first cavity 282, which contributes to the wind in the first cavity 282 entering the inlet of the fan 270, and can improve the ventilation effect. The fan 270 is gradually inclined downward from the front to the back, which can improve the space utilization rate. In any of the above-mentioned structures, the evaporator 230 and the fan 270 can share a drainage structure, which can simplify the structure, or the evaporator 230 and the fan 270 can adopt independent drainage structures to drain, which can reduce the impact of drainage on the fan 270. As shown in Figures 5, 6, 12 and 13, the drainage of the evaporator 230 is led out from the first drainage members 260 on both the left and right sides, and the drainage of the fan 270 is discharged from the rear end.

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

[0187] The rotation axis of the fan 270 is collinear with the central axis of the ventilation opening 244, and the flow guiding 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. The fan 270 is generally a centrifugal fan, which can change the flow direction of the wind so as to send the wind to the first section 410 or the second section 420. Of course, the fan 270 may be capable of achieving other circulating air blowing effects.

[0188] As can be understood, as shown in Figures 4 to 6, the first cover 241 is located above the fan 270, the first side of the flow guiding surface 2411 faces away from the drainage plate 100, and the second side of the flow guiding surface 2411 faces toward the drainage plate 100, and the first side of the flow guiding surface 2411 is inclined upward at a second included angle α2 relative to the second side of the flow guiding surface 2411, that is, facing away from the drainage plate 100, and the flow guiding surface 2411 of the first cover 241 is inclined upward at a second included angle α2, that is, the ventilation hole 244 faces the air supply direction of the first cavity 282, which contributes to the wind in the first cavity 282 entering the second cavity 281, which can improve the ventilation effect, and it is considered that the evaporator 230 and the fan 270 share the drainage structure so as to realize the simplification of the structure. As shown in FIGS. 14 to 16 and 21, the air-course component 200 drains water from the second drain outlet or the third drain outlet 2423 at the rear end.

[0189] As shown in Fig. 12 to Fig. 25, when the drainage plate 100 includes a water guide section and a drainage section 110, the drainage section 110 is configured with an outlet 114, and the 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 the influence of this structure, some wind also flows along the water guide section and the drainage section 110 to the outlet 114. If the outlet 114 and the ventilation opening 244 are offset, the wind flowing in the direction of the outlet 114 is prevented from being directly discharged from the ventilation opening 244, and the time of heat exchange of the wind in the first cavity 282 can be extended as much as possible, thereby improving the 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 the front to the rear. Of course, the first cavity 282 and the second cavity 281 may be provided on the left and right, and the direction away from the drainage plate 100 is the left-right direction, and the working principle is the same as the front-rear direction, so no further description 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, 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 a third included angle α3 in a direction away from the drainage plate 100, and the first cover 241 guides the water flow to the rear of the fan 270, contributing to the rapid discharge of the 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 drain plate 100, the fan cover 240, the water guide material 223, etc., 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] Air passage member 220 may be fixed to box liner body 300 by being fixedly connected to partition plate member 210 , or air passage member 220 may be fixedly connected directly to box liner body 300 .

[0194] The air passage member 220 includes a support plate and a second insulating layer 221 provided below the drainage plate 100, the support plate being supported below the second insulating layer 221, and the shape of the upper surface of the second insulating layer 221 conforming 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, reducing the outward diffusion of cold heat and ensuring 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, which 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, and 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 222 and the second support 225 are independent parts, such as plate members, and are attached by removable connection methods, such as insertion, locking, fasteners, etc., or the first support 222 and the second support 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 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 section 410 and second section 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 section 420 is opened in the front end of first support part 222, whereby second section 420 returns air into first cavity 282 through second air intake port 202 in the front end of air passage component 200.

[0199] 36 to 38, a first side of the first cavity 282 is provided with a first intake port 201, and a second side of the first cavity 282 is provided with a second intake port 202, which may be understood as a cross section of the first intake port 201 perpendicular to the respective intake directions forming an included angle with a cross section of the second intake port 202. The intake air through the first intake port 201 and the intake air through the second intake port 202 are intake 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 in the process of the air flow, part of the air is guided along the extension direction of partition 2221 and part 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] In the first cavity 282, a gap is provided between one end of the evaporator 230 facing the second side and the second intake port 202, and most of the intake air from the first intake port 201 and the second intake port 202 joins and comes into contact with each other at this gap, exchanges heat, and then flows further along the evaporator 230 to the exhaust port, and at the position of this gap, the partition portion 2221 plays a role of guiding a part of the intake air by the first intake port 201 in the extension direction of the partition portion 2221. In addition, it reduces the amount of air that comes into contact with and exchanges heat between the intake air of the first intake port 201 and the intake air of the second intake port 202, reduces the amount of frost at one end of the evaporator 230 close to the second side due to the difference in intake air temperature, avoids the effect on the intake air amount of the first cavity 282 due to the large amount of frost on the second side, solves the problem of a short defrost cycle due to the large amount of frost on the second side, appropriately extends the defrost cycle, and plays a role in saving power. By providing the partition 2221, the intake air through the first intake port 201 and the intake air through the second intake port 202 are held on both sides of the partition 2221 as much as possible.

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

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

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

[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 passage member 220 is provided with a guide surface 2222, which is a curved surface, and partition 2221 is located at a first end of guide surface 2222 and contacts 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 first cavity 282 from first air intake 201 can flow along the guide path of guide surface 2222; in other words, this portion of the air is made to flow along the curved surface of guide surface 2222, and the flow of some of the air is changed by guide surface 2222, so that some of the air flows along the extension direction of partition portion 2221, thereby reducing the amount of air that flows along the air intake direction of first air intake 201 and further reducing the amount of air that comes into contact and exchanges heat in the portion of the air intake from both first air intake 201 and second air intake 202.

[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 take in flow along the guide surface 2222, and the specific structure of the guide surface 2222 can be selected according to needs.

[0208] As shown in Figures 37 and 38, guide surface 2222 includes a flat portion 22222 and a curved portion 22221, one end of curved portion 22221 is connected to partition portion 2221 and the other end of curved portion 22221 is connected to flat portion 22222 and contacts flat portion 22222, flat portion 22222 extends toward the first wall surface, curved portion 22221 plays a role in changing the direction of air flow, flat portion 22222 can guide air to curved portion 22221, and flat portion 22222 cooperates with curved portion 22221 to make the intake of air by 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 a partition section 2221 is provided on both ends of the second air intake section, and the first side includes two side surfaces adjacent to the second side, i.e., a first air intake port 201 is 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 and 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 partition 2221 is 1 / 3 or less of the height of first air intake port 201, so that partition 2221 separates a portion of the intake air in the vertical direction, and has a relatively small effect on the intake effect of first air intake port 201, thereby ensuring the intake efficiency of 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 partitions a part of the intake air in the length 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 in air passage member 220, and partition 2221 does not require independent processing and attachment, which simplifies the assembly process of air passage component 200 and saves assembly time. Alternatively, partition 2221 is detachably connected to air passage member 220, and the structure and shape of partition 2221 can 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 or removably connected to the support member, in which case guide surface 2222 described above is also a part of the surface of the support member, and of course, a situation in which partition 2221 is integrally formed or removably connected to the heat insulating layer is not excluded.

[0216] The above-described embodiment of the partition portion 2221 and the embodiments of the guide surface 2222 and the flow guide plate 2223 associated with the partition portion 2221 may be provided in 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 function.

[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 described above. The air passage member 220 includes a support plate and a heat insulating layer located above the support plate, the support plate includes the first support portion 222 and the second support portion 225 described above, the heat insulating layer includes the second heat insulating layer 221 and the third heat insulating layer 224 described above, the second heat insulating layer 221 is provided above the first support portion 222, and the drainage plate 100 is provided above the second heat insulating layer 221.

[0218] As shown in Figures 20 to 25, the structure of the drainage plate 100 includes a drainage section 110 and a water guide section, the drainage section 110 is configured with an outlet 114, the drainage section 110 is recessed with respect to the ceiling surface of the drainage plate 100, the water guide section is connected to the drainage section 110, the water guide section is recessed with respect 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, and 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 required, 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, and the shape of the underside of the air duct component 200 is regular and the external structure is simple.

[0220] As shown in FIG. 37, the lower surface of the second insulation 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 passage component 200.

[0221] The second insulation 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 communicates with the drainage structure so as to drain the defrost water received by the drainage plate 100.

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

[0223] As shown in Figures 18 to 20, the evaporator 230 is horizontally placed in the first cavity 282 of the air passage component 200, and the drainage plate 100 serves to receive defrost water below the evaporator 230. The ceiling surface of the drainage plate 100 is parallel to the bottom surface of the evaporator 230. Here, the upper part of the drainage plate 100 in Figures 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 horizontal 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 with respect to the ceiling surface, and the included angle between the evaporator 230 and a 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, one end of the evaporator 230 facing the exhaust port is lower than one end of the evaporator 230 facing the intake port, and it may be understood that a connection line between the one end of the evaporator 230 facing the exhaust port and the one end of the evaporator 230 facing the intake port forms a predetermined angle with the horizontal plane, and this connection line may be located on the bottom surface of the evaporator 230 or on a symmetrical plane in the height direction. If the shape of the evaporator 230 is a rectangular parallelepiped, both the bottom surface and the symmetrical plane of the evaporator 230 form a predetermined angle with the horizontal direction.

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

[0228] Alternatively, the drainage plate 100 may be provided with a water guide portion recessed into the ceiling surface, and the evaporator 230 may be provided 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 equal to or smaller than a certain angle, so that the height of the entire air-duct component 200 can be reduced and the purpose of expanding 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-way component 200.

[0231] As can be understood, the evaporator 230 may be horizontally mounted above the drainage plate 100, and the bottom surface of the evaporator 230 may be understood to be parallel to the horizontal plane, and compared with the situation where the evaporator 230 is inclined, the height of the mounting space required for the horizontally mounted evaporator 230 is reduced, whereby the height-wise size of the air duct component 200 is accordingly reduced, and furthermore, the space occupied by the air duct component 200 in the box liner body 300 is reduced, and when the external size of the box liner body 300 remains unchanged, the capacity of the box liner body 300 can be effectively improved, so as 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 understood, the ceiling surface of the drainage plate 100 is flat and parallel to the horizontal plane, that is, the bottom surface of the evaporator 230 and the ceiling surface of the drainage plate 100 are both horizontally arranged, and the ceiling surface of the drainage plate 100 is located below the evaporator 230. The bottom surface of the evaporator 230 and the ceiling surface of the drainage plate 100 are parallel to each other or in contact with each other, so that the gap between the evaporator 230 and the drainage plate 100 is small, and the wind in the first cavity 282 can be prevented from flowing directly to the ventilation hole 244 through the gap between the evaporator 230 and the drainage plate 100, which contributes to the wind exchanging heat sufficiently in 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 exchanges 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, which 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 wind in the first cavity 282.

[0236] The following describes the structure of the evaporator 230. Note that, although the evaporator 230 will be described as being attached to the air passage component as an example, the evaporator 230 is not limited to being applied to the 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, so that the air intake through the first air intake port 201 flows through the ventilation section 23421 into the inside of the evaporator 230, and the air intake through the first air intake port 201 exchanges heat sufficiently.

[0238] Note that the ventilation portion 23421 may be provided in some of the heat sinks 234, or the ventilation portion 23421 may be provided in all of the heat sinks 234, and specifically, this can be selected according to need.

[0239] In the following, an example will be described in which some of the heat sinks 234 are provided with ventilation sections 23421.

[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 all connected to the heat exchange tube 233, and a plurality of the first heat sinks 2341 are arranged in parallel to form a first heat dissipation section, and 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 between the first heat sink 2341 and the first air intake 201). 23), the second heat sink 2342 is configured to have a ventilation section 23421 through which the air intake through the first air intake 201 passes, whereby a portion of the air intake through the first air intake 201 is diverted into the inside of the evaporator 230 via the ventilation section 23421, and further reduces the amount of air intake through the first air intake 201 and the air intake through the second air intake 202 that crosses, comes into contact, and exchanges heat, thereby reducing frost condensed due to the air intake through the first air intake 201 and the air intake through the second air intake 202 coming into contact and exchanging heat.

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

[0242] Here, the second heat sink 2342 is located on at least one side of the first heat sink 2341, that is, when the first air intake 201 is provided on one side of the air-path component 200, the second heat sink 2342 is located on the corresponding side, and when the first air intake 201 is provided on both opposing sides of the air-path component 200, the 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 201, the second air intake 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 the second heat sinks 2342 can be set as necessary, and one or more second heat sinks 2342 are provided. When one second heat sink 2342 is provided, a part of the intake air by the first air intake port 201 flows between the second heat sink 2342 and the first heat sink 2341 through the ventilation part 23421, and flows toward the exhaust port along the space between the second heat sink 2342 and the first heat sink 2341, and when multiple second heat sinks 2342 are provided, the wind flows through the ventilation part 23421 of the second heat sink 2342, along the space between the adjacent second heat sinks 2342, and between the second heat sink 2342 and the first heat sink 2341, and flows to the exhaust port, and the flow space of the wind is larger and the flow rate is better.

[0244] The ventilation portion 23421 of adjacent second heat sinks 2342 penetrates 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 offset 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 penetrating in a straight line, and ventilation portions 23421 communicating with each other in a staggered manner, resulting in a more diverse structure.

[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 ellipse, 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 notch, an ellipse with a notch, 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 necessary.

[0252] A first air intake 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. A second heat sink 2342 is symmetrically provided on both sides of the first heat dissipation section. A ventilation section 23421 is provided at positions corresponding to the two first air intakes 201 of the evaporator 230, ensuring that a portion of the air intake by both of the two first air intakes 201 can be diverted via 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-path component 200, and return air members 430 communicate with first air intake port 201, thereby realizing intake on both sides of air-path component 200.

[0254] The first heat sink 2341 and the second heat sink 2342 are provided above the drainage plate 100 so as to receive the defrost water of the evaporator 230 through the drainage plate 100, 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 obtains a weight change of the evaporator 230 and determines whether the evaporator 230 needs to perform defrosting based on the weight change. 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, the heat sink 234 of the evaporator 230 is provided with a locking groove for mounting the first heater 231, and the first heater 231 is locked to the heat sink 234 by the locking groove. The locking groove may be provided at a lower position 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 the 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 a first end of the evaporator 230 to a second end, the first end and the second end being opposite ends, thereby providing sufficient heat to the evaporator 230, where the second end and the first end are ends that form an 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 tube 233, and between the second heater 232 and the heat sink 234 in the heat exchange tube 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 are directly and integrally 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 independent of each other, the positions of the heating elements are flexible, and the heating elements can be easily replaced individually, and the heating elements can be easily attached and detached.

[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 providing sufficient defrosting over the entire surface of the evaporator 230.

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

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

[0267] In addition, 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 vertically installed in the cabinet 400, and the application scene 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, and can avoid the occurrence of leakage accidents caused by circuit failure, thereby improving 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] In the following, an example will be described 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 leakage current. In this case, the material of the drainage plate 100 is not limited, and the drainage plate 100 can be selected as a steel material, 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 plate 100 has an insulating and heat-conducting structure, and the composite heating layer is provided on the underside of the drainage plate 100, so that the drainage plate 100 has both heat-conducting and insulating functions, and the insulating layer can be omitted, so that the processing process of the drainage plate 100 is more simple and the production efficiency is improved. Here, the drainage plate 100 may be 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 is a combination of multiple kinds of electric heating materials. When the composite heating layer is energized, it can convert electric energy into thermal energy of the heating material 160 to provide heat for defrosting. Take the composite heating layer as an example, the graphene heating layer is a planar film of carbon atoms with a hexagonal honeycomb lattice, and has a thickness of only one atom, so that the thickness of the heating material 160 can be controlled.

[0276] In addition, if the heating material 160 is provided on the underside of the drainage plate 100, an insulating and heat-insulating layer needs to be provided below the composite heating layer to reduce the downward diffusion of heat and ensure the thermal efficiency of heating. 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 with a thermally conductive adhesive layer, which can realize the effect of heat conduction and at the same time realize the reliable connection between each layer.

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

[0278] When the composite heating layer adopts the graphene heating layer, the grid distribution of the graphene heating layer in different heating regions is different, so that the resistance distribution of the graphene heating layer in different heating regions is different. The underside of the drainage plate 100 may have two graphene heating layers with different resistances distributed thereon, or may have any number of graphene heating layers with different resistances distributed thereon. Furthermore, the graphene heating layers with different resistances may be connected in series, in parallel, or even connected to 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 drainage 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 the 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 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 wired 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 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 exhaust port, and an evaporator 230 and a drain plate 100 are provided in the first cavity 282, and air taken in by the air intake port is discharged from the exhaust port after heat exchange in the first cavity 282, and the 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 include air intakes at different temperatures.

[0285] The partition member 210 may be fixedly connected to the box liner body 300, for example, the edge of the partition member 210 is fixed to the box liner body 300 by welding, locking, fasteners, etc. As shown in Figures 6 and 20, the partition member 210 includes a first plate 211 and a second plate 212, the first plate 211 and the second plate 212 are provided with a first insulating layer 213, 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 insulation 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 insulation layer 213 is foam-molded integrally with the insulation layer of the cabinet 400, which improves the sealing performance between the partition plate member 210 and the box liner body 300 and prevents gas 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) defining 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) defining the mounting space serves to cover the second air intake 202 at the front end, thereby hiding the second air intake 202, and the lower side of the second air intake 202 is connected to the second section 420.

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

[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 intake port 201, a second intake port 202, and an exhaust port, the first intake port 201 and the second intake port 202 contain intake air of different temperatures, the first intake port 201 is located on a first side of the air passage component 200, the second 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 intake port 201 and the second 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 intake air through at least one of the first intake port 201 and the second intake port 202 to be diverted into the internal recess, that is, a portion of the intake air through at least one of the first intake port 201 and the second intake port 202 is diverted to the corresponding internal recess, thereby reducing the amount of air intake through the first intake port 201 and the second 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, the first air intake 201 and the second air intake 202 are located on different sides and the air intake directions cross each other. In the air intake process, part of the wind from the first air intake 201 is guided along the extension direction of the corresponding inner recess, and part of the wind continues to flow along the air intake direction. When the first air intake 201 and the second air intake 202 simultaneously intake air, the wind continuing to flow along the air intake direction crosses the air intake by the second air intake 202, and the amount of air that crosses between the air intake by the first air intake 201 and the air intake by the second air intake 202 is reduced. The principle of providing the inner recess in the area corresponding to the second air intake 202 is the same, and will not be described further here.

[0291] For example, in a case where 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 a portion of the air intake by the first air intake port 201 flows along the extension direction of the corresponding internal recess, and another portion 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 that is not adjacent to the second side, and the third side may be the side on which the exhaust port is located, the first internal recess 2121 is adjacent 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 air intake from the first air intake port 201 into the first cavity 282, a portion flows along the intake direction of the first air intake port 201 and crosses and comes into contact with the air intake by the second air intake port 202, and another portion 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 air intake port 201 and the air intake by the second air intake port 202, and further reducing the amount of frost.

[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 201 to the second air intake 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 to the exhaust outlet.

[0295] As shown in FIG. 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, the first guide surface 2122 inclines 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.

The first intake port 201 and the second intake port 202 may be located on opposite sides, and the interval between the first intake port 201 and the second intake port 202 may be increased, appropriately reducing the amount of air that crosses and exchanges heat.

[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 within 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, the first passage 312 and the second passage 218 are in one-to-one correspondence, and the cavity 216, the second passage 218, and the first passage 312 are connected to 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, the evaporator 230, the air passage member 220, the drainage plate 100 and other components are pre-assembled with the partition member 210 to form the air passage component 200, and the air passage component 200 is then loaded into the box liner body 300 and foamed together, thereby realizing a modularized mounting method. Compared with the mounting method in the related art, the mounting steps are effectively simplified, the mounting time is shortened, and the production efficiency is improved.

[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 is formed inside the partition member, and a second passage 218 is provided on the side of the partition member, and the second passage 218, the cavity 216, and the first passage 312 are connected to each other, thereby forming a foaming space, achieving integrated foam molding of the air duct component and the box liner main body 300, and ensuring the sealing performance of the connection portion of the air duct component 200.

[0369] The refrigeration equipment cabinet 400 includes a housing provided on the outside of 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 member 210, and a second passage 218 is provided on the side of the partition 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, realizing integrated foam molding of the air duct component and the cabinet, and simplifying the processing process.

[0370] In an embodiment of the present disclosure, partition member 210 is configured to have a recess 217 communicating with cavity 216, recess 217 communicating with second passage 218, recess 217 being provided around cavity 216, and urethane foam sealant enters recess 217 via second passage 218 and further enters the gap from a different direction via recess 217, thereby allowing the urethane foam sealant to quickly fill the entire gap and form 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 being U-shaped, and the side of the second plate 212 is provided with a through hole, i.e., a second passage 218, communicating with the recess 217. A groove is provided at 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 into the recess 217 through the second passage 218, and then enters the gap from a different direction through the recess 217, so that the urethane foam sealant quickly fills the entire gap and forms the first insulating layer 213, shortens the foaming time, and improves the foaming efficiency.

[0372] 41, a slot 311 is provided in the box liner main body 300, a side edge of the partition plate member 210 is engaged and connected to the slot 311, and a 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, so that the installation of the air passage component 200 can be completed, which effectively simplifies the mounting steps, shortens the mounting time, and improves the operation efficiency.

[0373] Here, the second passage 218 and the first passage 312 are both in the form of a through hole, and may of course be in the form of a slit. The specific structural form of the mounting structure is not limited to the slot 311, and may also be a snap fastener or other connection structure.

[0374] In the embodiment of the present application, as shown in Fig. 41, the box liner of the refrigeration equipment further includes a return air member 430, which is provided on the inner wall of the first compartment 410, and the return air member 430 communicates with the first intake port 201. When the fan 270 starts, 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, the temperature of the air is reduced and becomes cold air, and the cold 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, the maintenance of the return air member 430 is facilitated, the impact of the foaming process on the return air member 430 is avoided, the installation steps of the refrigeration equipment are simplified, and production efficiency is improved. Since 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 a positioning groove 313 is provided on the inner wall of the first section 410. The return air pipe 431 is fitted into the corresponding positioning groove 313, and the air outlet of the return air pipe 431 communicates with 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 large-capacity refrigeration equipment.

[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 matches 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 FIG. 41, the return air duct 431 is arranged in the vertical direction, and a main return air port 432 communicating with the air supply port of the return air duct 431 is formed at the upper end of the return air duct 431, and an auxiliary return air port 433 communicating with the air supply port of the return air duct 431 is formed on one side of the return air duct 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 sides of the left and right walls 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 the 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 is located within the cabinet and separates a first compartment and a second compartment, the air duct component includes a partition member, an air duct member, an evaporator and a drainage plate, the partition member and the air duct member define 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 are 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, the evaporator and the drainage plate are provided within the first cavity, the air duct member supports the drainage plate, the drainage plate is located below the evaporator, and an included angle between the evaporator and a horizontal plane is equal to or less than a predetermined angle, or the evaporator is parallel to the horizontal plane. The evaporator is placed horizontally within the air duct component, and the angle at which the evaporator is inclined downward relative to the horizontal direction may be controlled within a predetermined angle, or the evaporator may be installed horizontally, which allows the height space occupied by the evaporator to be reduced, and further reduces the height of the entire air duct component and the space within the cabinet occupied by the air duct component to be reduced, with the storage space within the cabinet correspondingly increased, and a large-capacity refrigeration equipment can be provided.

[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.
