Description

Technical Field

[0001] This invention relates to the field of household appliances, and more particularly to a refrigeration unit and a refrigeration device. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a low temperature to keep food or other items at a low temperature for preservation or long-term storage. Currently, the most commonly used type of refrigerator is the compressor refrigerator. A refrigerator uses an electric motor to provide mechanical energy, which is used by a compressor to perform work on the refrigeration components. Simultaneously, it utilizes the principle that a low-boiling-point refrigerant absorbs heat when it evaporates to achieve the purpose of cooling.

[0003] The components of the refrigeration system occupy a portion of the housing volume. The installation position of the refrigeration system components within the housing affects the housing volume and the size of the housing's storage space. In related technologies, the evaporator is located at the rear of the refrigeration compartment, resulting in a thicker housing and insufficient storage space in the depth direction. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the related art. To this end, the present invention proposes a liner for a refrigeration device.

[0009] In this embodiment of the refrigeration equipment, the liner has an upwardly recessed groove at the bottom of the partition component, and the evaporator is horizontally positioned within the groove. Since there is no need to separately construct a refrigeration compartment at the rear of the refrigeration chamber for the evaporator, the space occupied by the evaporator is effectively reduced, increasing the storage space of the liner in the depth direction and improving the space utilization rate of the refrigeration equipment.

[0020] According to one embodiment of the present invention, the air outlet direction of the first air outlet of the first drainage portion and / or the second drainage portion forms an acute angle with the rear wall of the liner body in the horizontal direction.

[0021] According to one embodiment of the present invention, the first drainage portion is located on the side of the rear wall near the left side wall of the liner body, the second drainage portion is located on the side of the rear wall near the right side wall of the liner body, and the connecting portion is located below the first drainage portion and the second drainage portion.

The extension direction of the water guide section forms a first angle with the air outlet direction above the drainage plate, and the depth of the recess of the water guide section gradually increases in the direction toward the drainage section.

[0029] According to one embodiment of the present invention, the bottom of the water guiding part is inclined in a first direction toward the drain section, and the first direction forms a second angle with the top surface of the drain plate.

[0030] According to one embodiment of the present invention, the depth of the drainage section recess gradually increases in the direction toward the outlet.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0073] Embodiments of the present invention, such as Figures 1 to 3As shown, a refrigeration device is provided, including a housing 400 and a liner of the refrigeration device as described in any of the following embodiments, wherein the liner of the refrigeration device is disposed inside the housing 400.

[0074] Refrigeration equipment can be various types of equipment such as refrigerators, freezers, display cases, vending machines, or wine cabinets. Refrigeration equipment can be used for refrigeration or freezing.

[0075] In the following embodiments, the directions of front, back, left, right, up, and down correspond one-to-one with the directions of the refrigeration equipment.

[0076] like Figures 1 to 3 As shown, the refrigeration equipment includes a refrigeration body 300 and a first air duct assembly 200. The interior of the refrigeration body 300 forms a compartment. The first air duct assembly 200 includes a partition component 210 and an evaporator 230. The partition component 210 is disposed in the compartment and divides the compartment into a first compartment 410 and a second compartment 420 that are independent of each other. The bottom of the partition component 210 has an upwardly recessed groove 215. The evaporator 230 is horizontally disposed in the groove 215.

[0077] In this embodiment of the refrigeration equipment, the liner has an upwardly recessed groove 215 at the bottom of the partition component 210, and the evaporator 230 is horizontally positioned within the groove 215. Since there is no need to separately construct a refrigeration compartment for the evaporator 230 at the rear of the refrigeration chamber, the space occupied by the evaporator 230 is effectively reduced, the storage space in the depth direction of the liner is increased, and the space utilization rate of the refrigeration equipment is improved. Because the evaporator 230 is horizontally positioned, the vertical space occupied by the evaporator 230 is reduced, decreasing the space occupied by the evaporator 230 within the chamber and further improving the space utilization rate of the refrigeration equipment.

[0078] In one embodiment of the present invention, such as Figure 3 As shown, the first air duct assembly 200 serves to separate compartments and also circulate air. It should be noted that the separation function of the first air duct assembly 200 is mainly achieved through the partition component 210. To ensure the independence of the first compartment 410 and the second compartment 420, the installation point between the first air duct assembly 200 and the housing body 300 must be sealed to prevent air leakage between the first compartment 410 and the second compartment 420.

[0079] The first air duct assembly 200 can divide the entire space inside the box body 300 into two parts: a first compartment 410 and a second compartment 420. Alternatively, the first air duct assembly 200 can divide a local space inside the box body 300 into two parts: a first compartment 410 and a second compartment 420.

[0080] The first air duct assembly 200 independently supplies air to the first compartment 410 and the second compartment 420. 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, the first compartment 410 is a refrigerator compartment and the second compartment 420 is a freezer compartment; of course, the first compartment 410 can also be a freezer compartment and the second compartment 420 a refrigerator compartment. When the functions of the first compartment 410 and the second compartment 420 are the same, such as both being refrigerator compartments, the temperature of the air supplied by the first air duct assembly 200 to both compartments is the same, regardless of whether the functions of the first compartment 410 and the second compartment 420 are the same.

[0081] When the housing 400 is connected to the door, and the door is in the closed position of the housing 400, the first compartment 410 and the second compartment 420 are two sealed and independent spaces; when the door is in the open position of the housing 400, items can be taken out or put in at least one of the first compartment 410 and the second compartment 420.

[0082] The number of first air duct components 200 installed in the refrigeration equipment can be set as needed.

[0083] In an embodiment of the present invention, the partition component 210 is connected to the liner body 300. The first cavity 260 between the partition component 210 and the air duct component 220 is used to install components such as the evaporator 230, the drain plate 100, and the heater 240 to meet the heat exchange requirements of the first compartment 410 and the second compartment 420. The partition component 210 can be fixedly connected to the liner body 300, for example, the edge of the partition component 210 can be fixed to the compartment of the liner body 300 by means of adhesive, snap-fit ​​or fasteners.

[0084] In embodiments of the present invention, such as Figures 4 to 6 As shown, the partition component 210 includes a first plate 211 and a second plate 212. The second plate 212 is disposed below the first plate 211, and a certain distance is spaced between the second plate 212 and the first plate 211. The second plate 212 and the first plate 211 form a cavity 216, which is filled with a first insulation layer 213. A groove 215 is located at the bottom of the second plate 212, and the shape and size of the groove are adapted to the shape and size of the evaporator 230. By providing the first insulation layer 213 in the cavity 216, the insulation performance of the first chamber 410 and the second chamber 420 can be improved, and heat exchange between the first chamber 410 and the second chamber 420 can be prevented. The first insulation layer 213 can be detachably disposed between the first plate 211 and the second plate 212, or the first insulation layer 213 can be integrally foamed with the first plate 211 and the second plate 212.

[0085] When the first insulation layer 213 is integrally foamed between the first plate 211 and the second plate 212, the first plate 211 and the second plate 212 can be fixedly installed in the compartment first, and the first insulation layer 213 is integrally foamed with the insulation layer of the inner tank body 300. The advantage of this installation is that the foam will fill the gap between the partition component 210 and the inner tank body 300, resulting in better sealing performance between the partition component 210 and the inner tank body 300, and preventing air leakage between the first compartment 410 and the second compartment 420.

[0086] In an embodiment of the present invention, the edge of the second plate 212 is recessed downward to form a recess 217 communicating with the cavity 216. The recess 217 is U-shaped, and a through hole, i.e., a second channel 2122, communicating with the recess 217 is provided on the side of the second plate 212. A groove 215 is provided at the bottom of the second plate 212. The gap between the middle of the second plate 212 and the first plate 211 is small, and the foaming adhesive enters the gap slowly during the foaming process. By providing the recess 217 on the edge of the second plate 212, the foaming adhesive first enters the recess 217 through the second channel 2122, and then enters the gap from different directions through the recess 217, so that the foaming adhesive quickly fills the entire gap to form the first insulation layer 213, shortening the foaming time and improving the foaming efficiency.

[0087] In embodiments of the present invention, such as Figures 7 to 9 As shown, the partition component 210 also includes a third plate 214, which, together with the first plate 211 and the second plate 212, defines an installation space. The third plate 214 is located in front of the first air duct assembly 200, and the installation space is located in front of the partition component 210. The installation space is used to install functional components, such as controllers, lighting modules, interactive modules, and display modules.

[0088] In embodiments of the present invention, such as Figure 4 As shown, the first air duct assembly 200 also includes an air duct component 220, which is disposed below the partition component 210. The air duct component 220 and the partition component 210 form a first cavity 260 that communicates with the groove 215. The air duct component 220 is also connected to the box body 300.

[0089] In embodiments of the present invention, such as Figure 7 , Figure 10 and Figure 11 As shown, the first air duct assembly 200 also includes a drain plate 100, which is disposed within the first cavity 260 and located below the evaporator 230. The drain plate 100 is located below the evaporator 230, and a water guide 223 is provided on the outlet 114 side of the drain plate 100. The water guide 223 communicates with the drain pipe 290, and the water discharged from the outlet 114 of the drain plate 100 is guided along the water guide 223 to the drain pipe 290.

[0090] It is understandable that the bottom surface of the evaporator 230 is parallel to the horizontal plane, which can be understood as the evaporator 230 being set horizontally. Compared with the case where the evaporator 230 is set at an incline, the height of the installation space required for the horizontally set evaporator 230 is reduced, so the dimension of the first air duct assembly 200 in the height direction can be reduced accordingly. As a result, the space occupied by the first air duct assembly 200 in the cabinet body 300 is reduced. Without changing the external dimensions of the cabinet body 300, the capacity of the cabinet body 300 can be effectively increased, so as to provide a large-capacity refrigeration device.

[0091] At this time, the installation state of the drain plate 100 is not limited. The top surface of the drain plate 100 is parallel to the bottom surface of the evaporator 230, or the top surface of the drain plate 100 is inclined downward from front to back relative to the bottom surface of the evaporator 230.

[0092] Understandably, the top surface of the drain plate 100 is also parallel to the horizontal plane, meaning that the bottom surface of the evaporator 230 and the top surface of the drain plate 100 are both placed horizontally. With the bottom surface of the evaporator 230 parallel to or in contact with the top surface of the drain plate 100, the gap between the evaporator 230 and the drain plate 100 is reduced. This prevents the air in the first cavity 260 from flowing directly from the gap between the evaporator 230 and the drain plate 100 to the air outlet, thus facilitating sufficient heat exchange within the first cavity 260.

[0093] It should be noted that minimizing the gap between the evaporator 230 and the drain plate 100 slows down the speed at which air flows from the gap between the evaporator 230 and the drain plate 100 to the air outlet, and prolongs the time the air stays in the first cavity 260, so that the air can fully exchange heat with the evaporator 230 in the first cavity 260 before flowing out, thus ensuring heat exchange efficiency.

[0094] Understandably, the air outlet of the first air duct assembly 200 and the outlet 114 of the drain plate 100 are misaligned to prevent the air flowing with the water to the outlet 114 from being directly discharged from the air outlet, thereby extending the heat exchange time of the air in the first cavity 260 and improving the heat exchange effect.

[0095] When the drainage plate 100 is constructed with a water guiding section 120 and a drainage section 110, and the drainage section 110 is constructed with an outlet 114, the water collected by the drainage plate 100 flows along the water guiding section 120 to the drainage section 110 and is discharged from the outlet 114. At the same time, a portion of the air also flows along the water guiding section 120 and the drainage section 110 to the outlet 114. By setting the outlet 114 and the air outlet to be misaligned, the air flowing to the outlet 114 can be prevented from being discharged directly from the air outlet, thus prolonging the heat exchange time of the air in the first cavity 260 as much as possible and improving the heat exchange effect.

[0096] In one embodiment of the present invention, such as Figures 4 to 10As shown, the first air duct assembly 200 also includes an air duct cover plate 251 and a fan 252 connected to the air duct cover plate 251. The fan 252 is offset from the outlet 114 of the drainage section 110. The air duct cover plate 251 has an air outlet corresponding to the position of the fan 252, so that the air in the first cavity 260 is discharged from the first cavity 260 through the air outlet under the action of the fan 252. The offset arrangement of the outlet 114 of the drainage plate 100 from the air outlet can slow down the speed at which the air at the outlet 114 is drawn out by the fan 252, and prolong the heat exchange time of the air in the first cavity 260.

[0097] The duct cover 251 is fixed to the inner tank body 300, and forms a second cavity 270 between itself and the rear wall 311 of the inner tank body 300. The second cavity 270 communicates with the first cavity 260 through an air outlet. Alternatively, the duct cover 251 itself forms the second cavity 270, which communicates with the first cavity 260. The duct cover 251 is fixedly installed on the inner tank body 300. A third cavity 280 is defined between the duct cover 251 and the water guide 223. The air in the first cavity 260 is then discharged by the fan 252 through the third cavity 280.

[0098] The air inlet, first cavity 260, and air outlet of the first air duct assembly 200 are connected to each other so that the air entering the air duct component 220 is discharged after heat exchange. The air inlet of the first air duct assembly 200 is divided into a second air inlet 2221 and a first air inlet 2121. The first cavity 260 is connected to the second air inlet 2221 and the first air inlet 2121 respectively. The first air duct assembly 200 is also provided with a first exhaust port and a second exhaust port 256. The second air inlet 2221, the first cavity 260, the air outlet, and the first exhaust port are connected to the first chamber 410 to form a first circulation path. The first air inlet 2121, the first cavity 260, the air outlet, and the second exhaust port 256 are connected to the second chamber 420 to form a second circulation path. The first circulation path and the second circulation path are connected alternately so that the first chamber 410 and the second chamber 420 are supplied with air independently. The number and location of the second air inlet 2221, the first air inlet 2121, the first air outlet, and the second air outlet 256 are not limited.

[0099] When the first chamber 410 is located above the second chamber 420, the partition component 210 is provided with a first air outlet communicating with the first cavity 260. The first air outlet passes through the first plate 211 and the second plate 212 in sequence. The first air outlet is located above the duct cover 251, and a first damper 255 is provided at the first air outlet for opening and closing adjustment. A second air outlet 256 is opened below the duct cover 251, and a second damper is provided at the second air outlet 256 for opening and closing adjustment. The duct cover 251 is provided with a first air guide 253 and a second air guide 254. The first air guide 253 and the second air guide 254 cooperate to deliver cold air to the first air outlet and the second air outlet 256.

[0100] In embodiments of the present invention, such as Figure 10 As shown, the air duct component 220 includes an air duct plate and a second insulation layer 221 disposed below the water plate 100. The air duct plate is supported below the second insulation layer 221. The shape of the upper surface of the second insulation layer 221 is adapted to the shape of the lower surface of the drainage plate 100, so that the first insulation layer 213 can fully insulate the drainage plate 100, reduce the outward diffusion of cold energy, and ensure heat exchange efficiency.

[0101] When the lower surface of the drainage board 100 is curved, such as wavy, the upper surface of the second insulation layer 221 is the corresponding curved surface; when the lower surface of the drainage board 100 is flat, the upper surface of the second insulation layer 221 is flat, and the specific settings can be configured as needed.

[0102] The air duct plate includes a first support portion 222 and a second support portion 225 that is inclined 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 first air duct assembly 200. The first support portion 222 supports the second insulation layer 221. A third insulation layer 224 is provided above the second support portion 225. A water guide 223 is provided above the third insulation layer 224. The second support portion 225 serves to support the third insulation layer 224 and the water guide 223.

[0103] The first support portion 222 and the second support portion 225 are independent parts, such as plates, and are installed by detachable connections, such as plug-in, snap-fit, and fasteners; or the first support portion 222 and the second support portion 225 are integrally formed, which can reduce the number of parts and simplify assembly. In some cases, the water guide 223 and the drainage plate 100 are two independent parts; of course, the water guide 223 and the drainage plate 100 can also be formed into an integral structure.

[0104] In some cases, a heater 240 is installed above the drain plate 100, that is, the heater 240 is located between the drain plate 100 and the evaporator 230. When the evaporator 230 needs to defrost, the heater 240 is turned on, and the heat generated by the heater 240 is used to heat the frost adhering to the surface of the evaporator 230.

[0105] Of course, the heater 240 is not limited to being positioned between the drain plate 100 and the evaporator 230. In this case, the heater 240 can be configured as a heating film, which is attached to the lower surface of the drain plate 100; or, the heater 240 can be positioned between the heat exchange tubes of the evaporator 230. For example, the heater 240 may include multiple straight-inserted heating rods or heating wires, with the heating rods inserted between two layers of heat exchange tubes. The lower heat exchange tubes serve to support the heating rods. In this case, the heat exchange efficiency between the heating rods and the heat exchange tubes, as well as the fins on the heat exchange tubes, is higher, and the defrosting efficiency can also be improved. When the heater 240 is not positioned between the drain plate 100 and the evaporator 230, the evaporator 230 can be placed directly on the drain plate 100, which can effectively reduce the gap between the evaporator 230 and the drain plate 100, thereby reducing the wind speed and improving the heat exchange efficiency.

[0106] In the above embodiments, the evaporator 230 is part of the refrigeration system in the refrigeration equipment. The refrigeration system includes a compressor, a condenser, a throttling element and the evaporator 230. The refrigerant in the refrigeration system evaporates and absorbs heat in the evaporator 230 to provide a cooling environment for the air in the first cavity 260.

[0107] Below, in conjunction with Figures 9 to 15 As shown, an embodiment of the drainage plate 100 is provided. Taking the drainage plate 100 installed in the first air duct assembly 200 described above as an example, the structure of the drainage plate 100 will be described. However, the drainage plate 100 is not limited to being installed in the first air duct assembly 200 described above. Other structures suitable for installing the drainage plate 100 in the following embodiment can also be used to install the drainage plate 100 described below.

[0108] One embodiment of the present invention, in conjunction with Figures 9 to 15 As shown, a drainage plate 100 is provided, which is configured with a drainage section 110 and a water guiding section 120. The drainage section 110 is configured with an outlet 114, and the drainage section 110 is recessed relative to the top surface of the drainage plate 100. The water guiding section 120 is connected to the drainage section 110, and the water guiding section 120 is recessed relative to the top surface of the drainage plate 100. The extending direction of the water guiding section 120 forms a first angle θ1 with the air outlet direction above the drainage plate 100. The depth of the recess of the water guiding section 120 gradually increases in the direction toward the drainage section 110.

[0109] In operation, the drain plate 100 is positioned below the evaporator 230 to collect condensate from water vapor condensing on the evaporator 230, as well as defrost water generated from frost on the evaporator 230 surface upon contact with heat. Water falls into the water guide section 120 and extends along its direction into the drain section 110. Multiple water guide sections 120 are typically provided, and the water collected in each section converges into the drain section 110 and is discharged through the outlet 114. The water guide sections 120 gradually increase in depth towards the drain section 110, allowing water to flow towards the drain section 110 under gravity and exit through the outlet 114.

[0110] When the aforementioned drain plate 100 and evaporator 230 are both disposed within the first air duct assembly 200, air enters the first cavity 260 from the air inlet of the first air duct assembly 200 and flows towards the air outlet. The air within the first cavity 260 flows in the space between the drain plate 100 and the evaporator 230, as well as within the space inside the evaporator 230. When the air flows between the drain plate 100 and the evaporator 230, the water guide 120 forms a first angle θ1 with the air outlet direction, which can prevent the air from flowing directly from the water guide 120 to the air outlet, thereby prolonging the time the air stays in the first cavity 260. This allows the air to fully contact the evaporator 230 and exchange heat, and the heat-exchanged air is then discharged from the air outlet, which helps to improve heat exchange efficiency.

[0111] The air outlet direction is from the air inlet to the air outlet. In some cases, only one air inlet and one air outlet are provided, forming a one-to-one correspondence and creating one air outlet direction. In other cases, at least one of the air inlets or outlets is provided, creating multiple air outlet directions. The extension direction of the water guide 120 forms an angle with at least one air outlet direction, ensuring heat exchange efficiency in one direction. Of course, if the extension direction of the water guide 120 forms an angle with all air outlet directions, it can ensure that the air in multiple flow paths can effectively exchange heat, thus guaranteeing heat exchange efficiency.

[0112] The air inlet is divided into a second air inlet 2221 and a first air inlet 2121. The second air inlet 2221 is located in front of the first air duct assembly 200, and the air outlet is located behind the first air duct assembly 200. The connecting path between the second air inlet 2221 and the air outlet forms a first air outlet direction. The second air inlet 2221 corresponds to a lower position of the evaporator 230, so the air flows in a downward and backward direction. In this embodiment, the extension direction of the water guide portion 120 of the drain plate 100 forms an angle with the first air outlet direction, that is, the extension direction of the water guide portion 120 forms an angle with the front-back direction. The first air inlet 2121 can be located on at least one of the left and right sides of the first air duct assembly 200. The connecting path between the first air inlet 2121 and the air outlet forms a second air outlet direction, and the extension direction of the water guide portion 120 also forms an angle with the second air outlet direction. The extension direction of the water guide 120 forms an angle with the first air outlet direction, and the extension direction of the water guide 120 also forms an angle with the second air outlet direction, both of which can be understood as the first angle θ1.

[0113] The extension direction of the water guide 120 can be a straight path or a curved path. When the extension path of the water guide 120 is a straight path, the path from the end of the water guide 120 away from the drain 110 to the other end of the water guide 120 connected to the drain 110 is the extension path. When the extension path of the water guide 120 is a curved path, the curved path water guide 120 can have multiple ends connected to the drain 110. The curved path can be a broken line path formed by connecting multiple straight paths, or a curve with one or more radii of curvature. The shape of the curved path can be set as needed. The extension direction of a water guide 120 can form one or more angles with the air outlet direction, that is, the first angle θ1 can be one or more angle values, which can be set as needed. The first angle θ1 is not marked in the figure, but the figure illustrates the case where the first angle is 90°.

[0114] It should be noted that both the water guiding part 120 and the drainage part 110 are recessed based on the top surface of the drainage plate 100. The top surface can be a plane or a curved surface, and can be a surface defined by multiple lines or multiple surfaces. Correspondingly, the bottom of the water guiding part 120 and the bottom of the drainage part 110 form the bottom surface of the drainage plate 100. The bottom surface can also be a plane or a curved surface, and can be a surface defined by multiple lines or multiple surfaces. The upper surface of the drainage plate 100 is the entire surface of the drainage plate 100 facing upwards, and the top surface is a part of the upper surface; the lower surface of the drainage plate 100 is the entire surface of the drainage plate 100 facing downwards, and the bottom surface is a part of the lower surface.

[0115] In this embodiment, the drainage plate 100, with its water guiding part 120 cooperating with the drainage part 110, can discharge the collected water, solving the drainage problem within the first air duct assembly 200. Furthermore, by setting the water guiding part 120 to form an angle between its extension direction and the air outlet direction of the first air duct assembly 200, the residence time of the air within the first air duct assembly 200 can be extended, which means extending the heat exchange time, thereby improving heat exchange efficiency and meeting the cooling requirements of the refrigeration equipment; and the structure of the drainage plate 100 is simplified.

[0116] Understandably, the bottom of the water guiding section 120 is inclined along a first direction towards the drain section 110, and the first direction forms a second angle θ2 with the top surface of the drain plate 100. That is, the bottom of the water guiding section 120 is inclined, and the water in the water guiding section 120 collects into the drain section 110 along the inclined path (first direction), which improves the drainage effect, avoids the problem of local water accumulation, and allows the water to flow smoothly.

[0117] When the top surface of the drainage plate 100 is horizontally positioned, it can be understood that the first direction forms a second angle θ2 with the horizontal plane. Along the top surface of the drainage plate 100, a water guiding section 120 gradually recesses downwards from the end furthest from the drainage section 110 towards the position communicating with the drainage section 110. At this time, the second angle θ2 is the angle between the bottom of the water guiding section 120 and the horizontal plane, and the first direction is a downward-sloping direction.

[0118] The bottom of the water guiding part 120 can be a slope or a slope. In some cases, the bottom of the water guiding part 120 is a slope. The slope can be a plane or a curved surface, which can be selected according to the needs.

[0119] In some cases, the bottom of the water guiding section 120 may not form a continuous slope or slope, such as a stepped shape, but it can still meet the water guiding requirements.

[0120] It is understandable that the second included angle θ2 is less than or equal to 7°. The small angle of the second included angle θ2 helps to reduce the distance between the top surface and the bottom surface of the drainage plate 100, which can realize drainage at a small angle, thereby reducing the size of the first air duct assembly 200 in the height direction, reducing the space occupied by the first air duct assembly 200, which helps to increase the storage space of the refrigeration equipment and provide a large-capacity refrigeration equipment.

[0121] In some cases, the second included angle θ2 is set to 3°. 3° can meet the drainage requirements of the drainage board 100 and also significantly reduce the height of the drainage board 100, thus achieving drainage at a small angle.

[0122] It is understandable that the bottom surfaces of the drainage plates 100 corresponding to the multiple water guide sections 120 arranged side by side on the same side of the drainage section 110 are coplanar, which makes the bottom surface of the drainage plate 100 more flat, the appearance of the drainage plate 100 simple, and convenient for positioning and installation.

[0123] The parallel arrangement here can be understood as multiple water guides 120 arranged sequentially on one side of the extension direction of the drainage section 110. Generally, multiple water guides 120 are arranged in parallel on both sides of the drainage section 110, that is, the drainage section 110 is positioned between two rows of water guides 120. Of course, when the drainage section 110 is located at the end of the drainage plate 100, the water guides 120 are only located on one side of the drainage section 110.

[0124] Understandably, the extension direction of the water guide section 120 is perpendicular to the air outlet direction, which can effectively prevent the air from being discharged from the space defined by the water guide section 120, and effectively prolong the time that the air stays in the first cavity 260, so as to fully exchange heat.

[0125] Understandably, the depth of the recess in the drainage section 110 gradually increases in the direction toward the outlet 114, so that the water in the drainage section 110 flows toward the outlet 114 under the action of gravity.

[0126] It is understandable that the bottom of the drainage section 110 is inclined along the second direction, and the second direction forms a third angle θ3 with the top surface of the drainage plate 100. That is, the bottom of the drainage section 110 is inclined, and the water in the drainage section 110 collects along the inclined path (second direction) to the outlet 114 and is discharged, which has a good drainage effect and can avoid the problem of local water accumulation; and the water can flow smoothly.

[0127] When the top surface of the drainage plate 100 is horizontally positioned, it can be understood that the second direction forms a third angle θ3 with the horizontal plane. A drainage section 110 is formed by gradually recessing downwards along the top surface of the drainage plate 100 towards the outlet 114. At this time, the third angle θ3 is the angle between the bottom of the drainage section 110 and the horizontal plane, and the second direction is a downward-sloping direction.

[0128] The bottom of the drainage section 110 can be a sloping line or a sloping surface. In some cases, the bottom of the drainage section 110 is a sloping surface, which can be a plane or a curved surface, depending on the specific needs.

[0129] In some cases, the bottom of the drainage section 110 may not form a continuous slope or ramp, such as a stepped shape, yet it can still meet drainage requirements.

[0130] It is understandable that the third included angle θ3 can be less than or equal to 7°. A small third included angle θ3 helps to reduce the distance between the top surface and the bottom surface of the drainage plate 100, enabling drainage at a small angle. This reduces the size of the first air duct assembly 200 in the height direction, shrinks the space occupied by the first air duct assembly 200, and helps to increase the storage space of the refrigeration equipment, providing a large-capacity refrigeration equipment.

[0131] It should be noted that the third included angle θ3 can also be greater than 7°. Since the area occupied by the drainage part 110 of the drainage plate 100 is small, the downward tilt angle of the drainage part 110 is slightly larger, which has little impact on the overall volume of the drainage plate 100. Therefore, the angle of the third included angle θ3 is not strictly limited.

[0132] It is understandable that the extension direction of the drain section 110 forms a fourth angle with the air outlet direction, which minimizes the amount of air discharged along the extension direction of the drain section 110 and also prolongs the time that the air stays in the first cavity 260, thus ensuring the heat exchange effect.

[0133] Of course, the drainage section 110 can also extend along the air outlet direction, and water guiding sections 120 can be symmetrically arranged on both sides of the drainage section 110 to facilitate uniform and stable water guiding by the water guiding sections 120 on both sides of the drainage section 110.

[0134] like Figure 11 and Figure 15 As shown, when the drainage section 110 extends along the air outlet direction, the water guide section 120 is perpendicular to the air outlet direction, so as to minimize the amount of air entering the water guide section 120.

[0135] It is understandable that, such as Figure 13 and Figure 14 As shown, the depth of the recess in the drainage section 110 is greater than or equal to the depth of the recess in the water guiding section 120. That is, the minimum depth of the drainage section 110 needs to be greater than or equal to the maximum depth of the water guiding section 120 so that the water in the water guiding section 120 can converge into the drainage section 110 and prevent water accumulation in the water guiding section 120.

[0136] It is understandable that, such as Figure 11 , Figure 12 as well as Figure 15 As shown, multiple parallel water guides 120 are provided on both sides of the drainage section 110. These multiple water guides 120 direct water from different locations into the drainage section 110. By providing multiple water guides 120, it can also be understood that both sides of the drainage section 110 form a wave-shaped structure, minimizing the area of ​​the top surface of the drainage plate 100 and reducing water accumulation on the top surface of the drainage plate 100, so that the water collected by the drainage plate 100 can be discharged from the outlet 114 as quickly as possible along the water guides 120 and the drainage section 110.

[0137] It is understandable that, such as Figure 11 and Figure 12 As shown, at least two drainage sections 110 are provided. Two or more drainage sections 110 have two or more outlets 114, enabling drainage from multiple locations and facilitating the rapid discharge of water from the drainage plate 100. With the drainage plate area remaining constant, increasing the number of drainage sections 110 can shorten the length of the water guiding section 120, allowing water to enter the drainage section 110 as quickly as possible.

[0138] Adjacent drainage sections 110 are a first drainage section 111 and a second drainage section 112. Between the first drainage section 111 and the second drainage section 112, a first water-guiding area 130 located on one side of the first drainage section 111 and a second water-guiding area 140 located on one side of the second drainage section 112 are constructed. Towards the first drainage section 111, the depth of the water-guiding portion 120 of the first water-guiding area 130 gradually increases; towards the second drainage section 112, the depth of the water-guiding portion 120 of the second water-guiding area 140 gradually increases. That is, at the junction of the first water-guiding area 130 and the second water-guiding area 140, the depth of the water-guiding portion 120 is the smallest, which facilitates the flow of water collected by the first water-guiding area 130 into the first drainage section 111 and the flow of water collected by the second water-guiding area 140 into the second drainage section 112, shortening the length of the water-guiding portion 120 and facilitating water collection in the drainage section 110.

[0139] Of course, such as Figure 13 As shown, only one drainage section 110 may be provided. In this case, the outlet 114 of the drainage section 110 should be avoided from the air outlet as much as possible. Multiple parallel water guiding sections 120 are provided on both sides of the drainage section 110, which helps to shorten the water guiding path of the water guiding section 120 and speed up water discharge.

[0140] like Figure 4 as well as Figures 12 to 14 As shown, the drain section 110 extends from front to back, with its opening located at the rear end of the drain plate 100. The water guide section 120 extends in the left-right direction, and the left and right sides of the drain section 110 form a wave-shaped structure. The wave-shaped structure facilitates water collection and discharge, thus eliminating the need for the evaporator 230 to be tilted in the front-back direction. The water guide section 120 forms an angle of less than 7° with the top surface of the drain plate 100. In other words, the drain plate 100 has a tilted water guide section 120 extending in the left-right direction, and the tilt angle of the water guide section 120 does not affect the angle of the drain plate 100 in the front-back direction. The drainage section 110 extends from front to back, forming a third angle θ3 with the horizontal plane. The third angle θ3 affects the height change of the drainage board 100 in the front-back direction. However, overall, the drainage section 110 is located in a local position of the drainage board 100, and the area occupied by the drainage section 110 is small. The local position of the drainage board 100 has a slightly larger inclination angle, which has little impact on the overall storage space in the room and can also optimize the volume of the room.

[0141] Understandably, reference Figure 14As shown, the water guiding section 120 includes a first guiding surface 121 provided along the extending direction of the water guiding section 120. From the top surface of the drainage plate 100 to the bottom surface, the first guiding surface 121 moves closer to its opposite side. That is, the longitudinal section of the water guiding section 120 narrows from top to bottom, so that the water falling on the first guiding surface 121 and the top surface can be collected at the bottom of the water guiding section 120 and then collected along the water guiding section 120 to the drainage section 110.

[0142] At least one of the two side surfaces of the water guiding section 120 along its extending direction is configured as a first guiding surface 121. The longitudinal cross-sectional shape of the water guiding section 120 may be an inverted triangle or an inverted trapezoid. (See reference) Figure 14 As shown, both sides of the water guiding section 120 in the extension direction are first guiding surfaces 121, and water can be guided on both sides of the water guiding section 120.

[0143] Understandably, reference Figure 13 As shown, the drainage section 110 includes a second guide surface 113 provided along the extending direction of the drainage section 110. From the top surface of the drainage plate 100 to the bottom surface, the second guide surface 113 moves closer to its opposite side so that the longitudinal section of the drainage section 110 converges from top to bottom. Water falling on the second guide surface 113 and the top surface can be collected at the bottom of the drainage section 110 and then discharged from the outlet 114.

[0144] At least one of the two side surfaces of the drainage section 110 along its extending direction is configured as a second guide surface 113. The longitudinal cross-sectional shape of the drainage section 110 may be an inverted triangle or an inverted trapezoid. (See reference) Figure 13 As shown, both sides of the drainage section 110 in the extension direction are second guide surfaces 113, and both sides of the drainage section 110 can be guided.

[0145] like Figure 13 and Figure 14 As shown, the water guiding section 120 is provided with a first guiding surface 121, and the drainage section 110 is provided with a second guiding surface 113, so as to fully guide the water so that the water collected by the drainage plate 100 can be discharged from the outlet 114 as soon as possible.

[0146] In the above embodiments, the first guide surface 121 and the second guide surface 113 can be planar or curved, and can be selected as needed.

[0147] It is understandable that, such as Figure 11 As shown, the edge of the drainage plate 100 is folded upward to form a flange 150. The flange 150 surrounds the drainage plate 100 and has an opening at the position corresponding to the outlet 114. The flange 150 serves to prevent water from overflowing from the upper surface of the drainage plate 100, so that all water on the upper surface of the drainage plate 100 is discharged along the outlet 114, thereby ensuring that all water in the first air duct assembly 200 is discharged from the drain pipe 290.

[0148] The flange 150 extends upward to form a positioning part 151. Two adjacent positioning parts 151 are used to limit the heater 240 above the drainage plate 100. The heater 240 is fixed in a simple way, and the structure of the drainage plate 100 is simple.

[0149] In the above embodiments, the shape of the drain plate 100 is related to the shape of the evaporator 230 and the first air duct assembly 200, and the shape of the drain plate 100 is not limited. The shape of the drain plate 100 can be rectangular, trapezoidal, circular, or other shapes. The upper surface and the lower surface of the drain plate 100 have the same shape.

[0150] In the above embodiment, the drainage plate 100 is applied in the first air duct assembly 200. That is, the drainage plate 100 is located below the evaporator 230. From front to back, the evaporator 230 does not need to be tilted downwards, which solves the problem that the tilting angle of the evaporator 230 will reduce the volume of the compartment. While ensuring the heat exchange efficiency in the first air duct assembly 200, it realizes defrosting and drainage at a small angle and reduces the height difference of the first air duct assembly 200, which helps to maximize the volume of the compartment.

[0151] Of course, in actual use, the evaporator 230 can also be tilted slightly downwards, but if the evaporator 230 is not tilted downwards, it will not affect the drainage effect.

[0152] When the drainage plate 100 in the above embodiments is applied to the first air duct assembly 200, the box liner, and the refrigeration equipment, the first air duct assembly 200, the box liner, and the refrigeration equipment have the beneficial effects of the drainage plate 100.

[0153] In one embodiment of the present invention, such as Figure 16 and Figure 17 As shown, the refrigeration unit also includes a second air duct assembly 500, which is disposed within the first compartment 410. The partition component 210 has a first exhaust port communicating with the first cavity 260, and the air inlet of the second air duct assembly 500 is connected to the first exhaust port. The second air duct assembly 500 is used to deliver cold air into the first compartment 410, and the volume of cold air delivered by the second air duct assembly 500 is related to the type of the first compartment 410. When the first compartment 410 is a refrigerator compartment and the second compartment 420 is a freezer compartment, the volume of cold air delivered by the second air duct assembly 500 to the first compartment 410 is greater than the volume of cold air entering the second compartment 420.

[0154] In an embodiment of the present invention, the second air duct assembly 500 includes an outer air duct plate 510. The outer air duct plate 510 includes a first flow guide portion 513 and a second flow guide portion 514 spaced apart, and a connecting portion 515 connected to the first flow guide portion 513 and the second flow guide portion 514 respectively. The outer air duct plate 510 forms a first flow channel 521. The first flow guide portion 513 and the second flow guide portion 514 are each provided with a first air outlet 511 that communicates with the first flow channel 521. The air inlet of the first flow channel 521 communicates with the first air outlet.

[0155] It should be noted that the first drainage part 513, the second drainage part 514, and the connecting part 515 are all located in the same plane, and the first drainage part 513, the second drainage part 514, and the connecting part 515 are integrally formed.

[0156] In an embodiment of the present invention, the air outlet 511 of the first air outlet of the first air outlet 513 and / or the second air outlet 514 forms an acute angle with the rear wall 311 of the liner body 300 in the horizontal direction.

[0157] By making the air outlet 511 of the first air outlet 513 and / or the second air outlet 514 form an acute angle with the rear wall 311 of the liner body 300 in the horizontal direction, the cold air output through the first air outlet 511 first contacts the corresponding side wall of the liner body 300, thereby reducing the wind speed and changing the wind direction of the cold air. The cold air diffuses to different areas of the room, making the temperature in the room more uniform and improving the cooling efficiency. Since the cold air does not blow directly to the junction of the liner and the door, the problem of cold air leakage through the junction of the liner and the door is effectively avoided, further improving the cooling efficiency.

[0158] In one embodiment of the present invention, such as Figures 16 to 18 As shown, the outer panel 510 of the air duct is U-shaped and is disposed within the compartment. The first drainage section 513 is located on the rear wall 311 near the left side wall 312 of the inner box body 300, and the second drainage section 514 is located on the rear wall 311 near the right side wall 313 of the inner box body 300. The connecting section 515 is located below the first drainage section 513 and the second drainage section 514. Because a hollow area is formed between the first drainage section 513 and the second drainage section 514, the storage space in the depth direction of the hollow area is increased, further improving the capacity of the inner box body 300.

[0159] In an embodiment of the present invention, the first air outlet 511 of the first drainage section 513 and the first air outlet 511 of the second drainage section 514 are arranged opposite to each other. That is, the first air outlet 511 of the first drainage section 513 is located on the right side of the first drainage section 513, and the first air outlet 511 of the second drainage section 514 is located on the left side of the second drainage section 514.

[0160] like Figure 20 As shown, when cold wind ( Figure 20 (Left arrow) After the cold air is blown out through the first air outlet 511 of the first air intake section 513, it blows towards the right side wall 313 of the box body 300. After the cold air comes into contact with the right side wall 313 of the box body 300, the flow direction of the cold air changes, and the cold air begins to diffuse into different areas of the compartment. Similarly, when the cold air is blown out through the first air outlet 511 of the second air intake section 514, it blows towards the left side wall 312 of the box body 300. After the cold air comes into contact with the left side wall 312 of the box body 300, the flow direction of the cold air changes, and the cold air begins to diffuse into different areas of the compartment. Since the items are placed in the compartment and come into contact with the front of the air intake section, placing the first air outlet 511 on the side of the air intake section can prevent the items in the compartment from blocking the first air outlet 511, thus enhancing the airflow effect.

[0161] It should be noted that the air outlet 511 of the first air intake section 513 forms a first acute angle with the rear wall 311 in the horizontal direction, and the air outlet 511 of the second air intake section 514 forms a second acute angle with the rear wall 311 in the horizontal direction. The first acute angle and the second acute angle are equal. Of course, the first acute angle and the second acute angle may not be equal.

[0162] In embodiments of the present invention, such as Figure 18 As shown, the air outlet 512 is located on the side of the connecting portion 515 away from the rear wall 311, that is... Figure 18 The front side of the connecting part 515. The interior of the connecting part 515 is provided with a second flow channel 526 that communicates with the air outlet 512. The air inlet of the second flow channel 526 is located at the bottom of the connecting part 515, and the air inlet of the second flow channel 526 communicates with the first air outlet provided on the partition member 210.

[0163] When the lower part of the compartment is a closed compartment, it is difficult for cold air from inside the compartment to enter the closed compartment, resulting in poor refrigeration performance. To ensure better refrigeration performance in the closed compartment, an air outlet 512 is installed on the side of the connecting part 515 away from the rear wall 311, and the air outlet 512 is connected to the closed compartment. The cold air generated by the evaporator 230 enters the closed compartment sequentially through the second flow channel 526 and the air outlet 512.

[0164] It should be noted that enclosed compartments can be in the form of drawers or enclosed storage boxes.

[0165] In embodiments of the present invention, such as Figure 21 As shown, at least one of the air inlets of the first flow channel 521 and the second flow channel 526 is provided with a flow regulating plate 528.

[0166] In one embodiment of the present invention, such as Figure 21 As shown, the flow regulating vane 528 is disposed within the air inlet of the second flow channel 526. When the flow regulating vane 528 is perpendicular to the length direction of the second flow channel 526, the passage for cold air to enter the second flow channel 526 is reduced, and only a small amount of cold air enters the second flow channel 526. When the flow regulating vane 528 is aligned with the length direction of the second flow channel 526, the passage for cold air to enter the second flow channel 526 is increased, allowing more cold air to enter the second flow channel 526. By setting the flow regulating vane 528, the airflow rate of cold air entering the corresponding flow channel unit can be changed. Users can adjust the cooling effect according to the food arrangement and type of food in the room. For easy adjustment, the end of the pin away from the rear wall 311 can pass through the insulation member 520 and the connecting part 515 before entering the room, allowing the user to manually rotate the pin inside the room to adjust the flow regulating vane 528.

[0167] In embodiments of the present invention, such as Figure 18 and Figure 19 As shown, the first flow channel 521 is U-shaped and includes a first flow channel unit 524 located inside the first intake section 513 and a second flow channel unit 525 located inside the second intake section 514. The air inlet of the first flow channel 521 is located at the bottom of the connecting section 515. The first flow channel unit 524 is connected to the first air outlet 511 located in the first intake section 513, and the second flow channel unit 525 is connected to the first air outlet 511 located in the second intake section 514. The first flow channel unit 524 and the second flow channel unit 525 are respectively connected to the air inlet of the first flow channel 521. The air inlet of the first flow channel 521 is connected to the first exhaust port through the first damper 255. The air inlet of the first flow channel 521 is provided with a guide vane 523, which is adapted to change the air intake volume of the first flow channel unit 524 and the second flow channel unit 525.

[0168] The cold air generated by the evaporator 230 enters the first flow channel 521 through the first exhaust port. Guided by the guide vanes 523, part of the cold air enters the first flow channel unit 524 and then enters the room through the first air outlet 511 of the first intake section 513. The other part of the cold air enters the second flow channel unit 525 and then enters the room through the first air outlet 511 of the second intake section 514. Because the two intake sections output cold air in different directions, the cold air can enter different areas of the room, making the temperature inside the room more uniform.

[0169] In an embodiment of the present invention, a heat insulation component 520 is provided inside the outer panel 510 of the air duct. The shape of the heat insulation component 520 is adapted to the shape of the outer panel 510 of the air duct, and the heat insulation component 520 is also U-shaped. A first flow channel 521 is disposed in the heat insulation component 520, and the heat insulation component 520 is provided with a first air duct 522 connecting the first flow channel 521 and the first air outlet 511. The heat insulation component 520 is used to prevent the cold air in the first flow channel 521 from exchanging heat with the outside environment, thus affecting the refrigeration effect.

[0170] In an embodiment of the present invention, the refrigeration equipment further includes an inner duct plate 530, and an opening is formed on the side of the outer duct plate 510 facing the rear wall 311. The shape of the inner duct plate 530 is adapted to the shape of the outer duct plate 510, and the inner duct plate 530 has a U-shaped plate structure, covering the opening. The first flow channel 521 is located on the side of the insulation member 520 facing the inner duct plate 530. The connection between the inner duct plate 530 and the outer duct plate 510 can be in various ways, such as by snap-fit ​​connection, integral molding, adhesive bonding, or screw connection, etc.

[0171] It should be noted that the first flow channel 521 can also be located inside the insulation component 520, or the first flow channel 521 can be located on the side of the insulation component 520 away from the inner plate of the air duct 530.

[0172] In an embodiment of the present invention, the width of the air inlet of the first flow channel 521 is greater than the width of the first flow channel 521. By making the width of the air inlet of the first flow channel 521 greater than the width of the first flow channel 521, after the cold air enters the first flow channel 521 through the air inlet, the flow rate of the cold air increases due to the narrowing of the flow channel, thereby increasing the speed at which the cold air is output through the first air outlet 511.

[0173] It should be noted that the width of the air intake refers to the dimension perpendicular to the rear wall 311, while the length of the air intake refers to the dimension parallel to the rear wall 311.

[0174] The following is combined Figures 16 to 21 A specific embodiment of the present invention is described below: Figures 16 to 21 middle,

[0175] The outer duct panel 510 is installed in the first chamber 410. The outer duct panel 510 has a U-shaped plate structure. An insulation component 520 is installed inside the outer duct panel 510. The shape of the insulation component 520 is adapted to the shape of the outer duct panel 510. An opening is formed on the side of the outer duct panel 510 facing the rear wall 311. The shape of the inner duct panel 530 is adapted to the shape of the outer duct panel 510. The inner duct panel 530 is also U-shaped and covers the opening.

[0176] The outer panel 510 of the air duct includes a first air intake section 513 and a second air intake section 514 arranged at intervals, and a connecting section 515 connected to the first air intake section 513 and the second air intake section 514 respectively. The first air intake section 513 and the second air intake section 514 are each provided with three first air outlets 511. The first air outlets 511 are strip-shaped air outlets and are suitable for delivering cold air into the first room 410. The air outlet direction of the first air outlets 511 of the first air intake section 513 and the second air intake section 514 forms an acute angle with the rear wall 311 in the horizontal direction.

[0177] The first air intake section 513 is located on the rear wall 311 near the left side wall 312 of the liner body 300. The second air intake section 514 is located on the rear wall 311 near the right side wall 313 of the liner body 300. The connecting section 515 is located below the first air intake section 513 and the second air intake section 514, forming a hollow area between the first air intake section 513 and the second air intake section 514. Three first air outlets 511 are located on the right side of the first air intake section 513 and are arranged at intervals along the vertical direction. Three first air outlets 511 are located on the left side of the second air intake section 514 and are arranged at intervals along the vertical direction.

[0178] The insulation component 520 is also U-shaped, with a first flow channel 521 located on the side of the insulation component 520 facing the inner air duct plate 530. The insulation component 520 has a first air duct 522 connecting the first flow channel 521 and the first air outlet 511. The first air duct 522 is a notch in the insulation component 520, located at the edge of the hollow area of ​​the insulation component 520. The position of the first air duct 522 corresponds one-to-one with the position of the first air outlet 511. The insulation component 520 also has a second air duct 527 connecting the second flow channel 526 and the air nozzle 512. The insulation component 520 is made of polyurethane, but other insulation materials can also be used.

[0179] The first flow channel 521 is U-shaped and includes a first flow channel unit 524 located inside the first intake section 513 and a second flow channel unit 525 located inside the second intake section 514. The air inlet of the first flow channel 521 is located at the bottom of the connecting section 515. The first flow channel unit 524 is connected to the first air outlet 511 located in the first intake section 513, and the second flow channel unit 525 is connected to the first air outlet 511 located in the second intake section 514. The first flow channel unit 524 extends vertically, and its lower end is connected to the air inlet of the first flow channel 521. The second flow channel unit 525 is an arc-shaped channel, and its corners are rounded to reduce air resistance inside the second flow channel unit 525. The air inlet of the first flow channel 521 is connected to the first exhaust outlet through a first damper 255. The air inlet of the first flow channel 521 is provided with a guide vane 523, which has a triangular block structure and is integrally formed with the insulation component 520. The guide vane 523 is suitable for changing the air intake volume of the first flow channel unit 524 and the second flow channel unit 525.

[0180] The connecting part 515 is provided with an air outlet 512, which is located on the side of the connecting part 515 away from the rear wall 311. The lower part of the insulation member 520 facing the outer plate 510 of the air duct is provided with a second flow channel 526 that communicates with the air outlet 512. The air inlet of the second flow channel 526 is located at the bottom of the connecting part 515, and the air inlet of the second flow channel 526 is connected to the first air outlet through the first air damper 255.

[0181] In embodiments of the present invention, such as Figure 22 As shown, the inner box body 300 is provided with a first channel 430, the partition component 210 has a cavity 216 inside, and the partition component 210 has a second channel 2122 on its side. The first channel 430 and the second channel 2122 correspond one-to-one, and the second channel 2122 is connected to the cavity 216 and the first channel 430 respectively.

[0182] It should be noted that the second channel 2122 can be located on the side of the second plate 212 or on the side of the first plate 211.

[0183] According to an embodiment of the present invention, the refrigeration equipment liner is provided with a first channel 430 in the liner body 300 and a second channel 2122 on the side of the partition component 210. After the partition component 210 is installed into the liner body 300, the first channel 430 and the second channel 2122 constitute a foaming adhesive channel for the foaming adhesive to enter the cavity 216, so that the partition component 210 can be foamed together with the liner body 300. Before foaming, components such as the evaporator 230, the air duct component 220 and the drain plate 100 can be pre-assembled into the partition component 210 to form a first air duct assembly 200, and then the first air duct assembly 200 is installed into the liner body 300 for foaming together, realizing a modular installation method. Compared with the installation method in related technologies, this method effectively simplifies the installation steps, shortens the installation time, and improves production efficiency.

[0184] In an embodiment of the present invention, the inner casing 300 is provided with a mounting part, and the side of the partition component 210 is connected to the mounting part. During installation, by pre-assembling components such as the evaporator 230, the air duct component 220, and the drain plate 100 onto the partition component 210, and then connecting the side of the partition component 210 to the mounting part, the installation of the first air duct assembly 200 can be completed, effectively simplifying the installation steps, shortening the installation time, and improving work efficiency.

[0185] In an embodiment of the present invention, the mounting part is a slot 440 provided in the inner box body 300, the side of the partition component 210 is snapped into the slot 440, and the first channel 430 is a through hole provided in the slot 440. During installation, it is only necessary to snap the side of the partition component 210 into the slot 440, and then foam the partition component 210 and the inner box body 300 together.

[0186] It should be noted that both the second channel 2122 and the first channel 430 are through holes, although they could also be strip-shaped slots. The specific structural form of the mounting part is not limited to the slot 440; it could also use a snap-fit ​​or other connecting structure.

[0187] In embodiments of the present invention, such as Figure 23 and Figure 24 As shown, the refrigeration unit also includes a return air duct assembly 600, which is disposed on the inner wall of the first compartment 410 and is connected to the first air inlet 2121. When the fan 252 rotates, the air in the first compartment 410 enters the first cavity 260 through the return air duct assembly 600 and exchanges heat with the evaporator 230. The air temperature decreases and becomes cold air, which then enters the first compartment 410 and the second compartment 420 through the first exhaust port and the second exhaust port 256, respectively.

[0188] By placing the return air duct assembly 600 on the inner wall of the first chamber 410, maintenance of the return air duct assembly 600 is facilitated, the impact of the foaming process on the return air duct assembly 600 is avoided, the installation steps of the refrigeration equipment are simplified, and production efficiency is improved. Since the return air duct assembly 600 is located inside the first chamber 410, the space between the inner chamber body 300 and the shell is reduced, the storage space of the inner chamber body 300 is increased, and the capacity of the inner chamber body 300 is effectively improved.

[0189] In embodiments of the present invention, such as Figure 23 and Figure 24 As shown, the return air duct assembly 600 includes a first return air duct 610. The inner wall of the first compartment 410 is provided with a positioning groove. The first return air duct 610 is embedded in the corresponding positioning groove. The air outlet of the first return air duct 610 is connected to the corresponding first air inlet 2121.

[0190] By embedding the first return air duct 610 into the positioning groove, the space occupied by the return air duct assembly 600 is reduced, which helps to increase the storage space of the refrigeration equipment and provides a large-capacity refrigeration equipment. Since the return air duct assembly 600 is located in the room, the installation steps of the refrigeration equipment are simplified, and the maintenance of the return air duct assembly 600 is convenient.

[0191] It should be noted that the installation location of the return air duct assembly 600 is not limited to inside the room. The return air duct assembly 600 can also be installed outside the first room 410, that is, between the inner liner body 300 and the outer shell. The number of first return air ducts 610 is not limited to one; two or more first return air ducts 610 can be installed.

[0192] In an embodiment of the present invention, the air outlet of the first return air duct 610 is detachably connected to the first air inlet 2121. By detachably connecting the air outlet of the first return air duct 610 to the first air inlet 2121, the installation and disassembly of the first return air duct 610 can be facilitated, as well as the subsequent maintenance of the first return air duct 610.

[0193] It should be noted that the shape and size of the first air inlet 2121 are adapted to the shape and size of the air outlet of the return air duct assembly 600. The first air inlet 2121 can be located on the side of the first plate 211 or on the side of the second plate 212.

[0194] In embodiments of the present invention, such as Figure 23 and Figure 24 As shown, the outlet of the first return air duct 610 is provided with a plug-in part, which is inserted into the corresponding first air inlet 2121.

[0195] In embodiments of the present invention, such as Figure 23 and Figure 24As shown, the first return air duct 610 is arranged vertically. A main return air inlet 611, communicating with the air outlet of the first return air duct 610, is formed at the upper end of the first return air duct 610. An auxiliary return air inlet 612, communicating with the air outlet of the first return air duct 610, is formed on one side of the first return air duct 610. A grille is provided on the main return air inlet 611. By providing a grille on the main return air inlet 611, it is possible to prevent debris inside the refrigerator from being drawn into the main return air inlet 611, thus preventing blockage of the main return air inlet 611.

[0196] In an embodiment of the present invention, the return air duct assembly 600 includes two first return air ducts 610. The left side wall 312 and right side wall 313 of the first chamber 410 are respectively provided with vertically extending positioning grooves, located on the side of the left side wall 312 and right side wall 313 near the door. The two first return air ducts 610 are respectively embedded in their corresponding positioning grooves. The air outlet of the first return air duct 610 is provided with a plug-in portion, which is inserted into the corresponding first air inlet 2121. A main return air inlet 611 communicating with the air outlet of the first return air duct 610 is formed at the upper end of the first return air duct 610. An auxiliary return air inlet 612 communicating with the air outlet of the first return air duct 610 is formed on one side of the first return air duct 610. The main return air inlet 611 is provided with a grille.

[0197] Since the cold air temperature is highest near the door, by setting the return air duct assembly 600 on the inner wall near the door, the return air duct assembly 600 can return the cold air near the door to the first cavity 260 for heat exchange, effectively preventing the cold air from the first air outlet 511 from directly entering the return air duct assembly 600, thus improving the cooling efficiency of the refrigeration equipment.

[0198] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
