Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a refrigeration appliance and a manufacturing method thereof. Background Art

[0002] In a refrigeration appliance, a module for improving the air quality may be provided. Taking a refrigerator as an example, a purification module may be provided in the air duct of the refrigerator. In order to install the purification module in the air duct, a complicated operation is usually required.

[0003] The purification module is usually installed on the air duct cover, and at least a part of the purification module needs to be located in the air duct so as to purify the gas in the air duct. In existing refrigerators, the purification module is usually installed on the air duct cover first, and then one or more components for forming the air duct are assembled to the air duct cover and the purification module. The assembly process is complicated and has high requirements for the operator. Otherwise, it is easy to cause damage to the components during the assembly process. Conversely, when disassembling the purification module, it is necessary to remove the components for forming the air duct first. The disassembly process of the purification module is also very complicated. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an improved refrigeration appliance and a manufacturing method thereof, so as to overcome at least one of the above-mentioned deficiencies of the prior art.

[0005] According to a first aspect of the present application, an embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment, which is provided with a storage space for accommodating items to be cooled; a duct module for forming an air duct in the compartment, which includes a duct body for defining the air duct and a duct cover installed to a side of the duct body facing the storage space; and a purification module, which is at least partially located in the air duct to purify the gas flowing through the air duct. The duct module is configured to allow the purification module to be installed to the duct cover from a side of the duct body facing away from the duct cover when the duct body and the duct cover are assembled with each other.

[0006] Thus, the assembly and / or disassembly process of the air duct module and the purification module can be simplified. When assembling the refrigeration appliance, the air duct module can be provided as an assembled whole by the manufacturer of the air duct module, for example. The assembler of the refrigeration appliance can directly operate the assembled air duct module without performing the assembly operation of the air duct body and the air duct cover. Thus, the difficulty of the assembly operation can be reduced. Similarly, during the disassembly process, the difficulty of the operation can also be reduced with the help of the present invention. In addition, the air duct module can be prevented from being damaged during the assembly process and / or disassembly process.

[0007] According to an optional embodiment of the present application, the purification module may be configured to be installed on the air duct cover from the side of the air duct body facing away from the air duct cover in a direction perpendicular to the main plane of the air duct cover. Thus, the installation operation of the purification module can be made simpler and the structure of the air duct module will not be complicated. In this article, the "main plane of the air duct cover" may refer to the plane where the area of ​​the air duct cover with the largest area is located.

[0008] According to an optional embodiment of the present application, the air duct body may be provided with a mounting hole. The mounting hole may completely penetrate the air duct body in a direction perpendicular to the air duct cover.

[0009] For example, the purification module may extend into the installation hole or pass through the installation hole from the side of the air duct body facing away from the air duct cover, so as to be installed on the air duct cover.

[0010] Alternatively or additionally, the mounting bracket of the air duct cover extends into the mounting hole, and the purification module can be mounted to the air duct cover through the mounting bracket.

[0011] According to an optional embodiment of the present application, the mounting bracket can extend through and beyond the mounting hole. The purification module can be mounted to the air duct cover by means of the mounting bracket without extending into the first through hole. Thus, the first through hole can be allowed to have a smaller size. The purification module can be mounted to the air duct cover in a direction perpendicular to the main plane of the air duct cover, and can also be mounted to the mounting bracket in a direction parallel to the air duct cover. Therefore, there are more options for the connection mode of the purification module and the mounting bracket.

[0012] According to an optional embodiment of the present application, the air duct body may include a heat insulation board at least partially located between the air duct and the air duct cover. The heat insulation board may be provided with a first through hole.

[0013] Optionally, the purification module may extend into the first through hole from a side of the heat insulation board facing away from the air duct cover so as to be mounted on the air duct cover.

[0014] Alternatively or additionally, the mounting bracket of the air duct cover may extend into the first through hole, so that the purification module can be mounted to the air duct cover through the mounting bracket.

[0015] According to an optional embodiment of the present application, along the projection direction perpendicular to the main plane of the air duct cover, the projection of the first through hole may be smaller than the projection of the portion of the purification module located in the air duct. The smaller first through hole can effectively prevent condensation from occurring at a position corresponding to the purification module on the side of the air duct cover facing the storage space.

[0016] Alternatively or additionally, at least a portion of the heat insulation board may be projected onto the purification core of the purification module in a direction perpendicular to the main plane of the air duct cover. Obviously, at least a portion of the heat insulation board is an integral part of the heat insulation board, rather than a separate component. Thus, at least a portion of the heat insulation board can be used to effectively separate the air duct cover from the purification core of the purification module in a heat-insulating manner. Therefore, there is no need to additionally provide a heat insulation component in the purification module, thereby simplifying the structure and significantly reducing costs. This configuration can prevent condensation from occurring on the side of the air duct cover facing the storage space at a position corresponding to the purification module, and can simplify the structure and the installation process.

[0017] For example, the purification core of the purification module can be at least mostly projected onto the insulation board in a direction perpendicular to the main plane of the air duct cover. Thus, the insulation board can be effectively used to prevent condensation from occurring on the side of the air duct cover facing the storage space at a position corresponding to the purification module.

[0018] According to an optional embodiment of the present application, the heat insulation board may be provided with a receiving recess at a position opposite to the purification module in a direction perpendicular to the main plane of the air duct cover. The receiving recess is recessed in a direction away from the purification module.

[0019] According to an optional embodiment of the present application, the heat insulation board may be provided with a convex column located in the air duct. The convex column may penetrate the air duct in a direction perpendicular to the main plane of the air duct cover. The convex column may be arranged adjacent to the first through hole. Thus, the structural strength may be improved.

[0020] According to an optional embodiment of the present application, the convex column may be arranged successively with the first through hole along the main flow direction of the air duct, thereby reducing the obstruction of the convex column and the purification module to the gas flow.

[0021] According to an optional embodiment of the present application, the air duct body may include an air duct back plate that bounds the air duct at least on a side of the air duct facing away from the air duct cover. The air duct back plate may be provided with a second through hole. The purification module may pass through the second through hole or extend into the second through hole from a side of the heat insulation board facing away from the air duct cover so as to be mounted on the air duct cover.

[0022] According to an optional embodiment of the present application, the purification module can close the second through hole, thereby preventing the gas in the air duct from leaking through the second through hole.

[0023] The purification module may be provided with a purification rear wall, which is located on the side of the air duct back plate facing away from the air duct and completely closes the second through hole, which further helps to prevent gas leakage in the air duct.

[0024] According to an optional embodiment of the present application, the refrigeration appliance may include a covering film, which is attached to the duct back plate at a side of the duct back plate facing away from the duct and covers the second through hole and / or the purification module. This also helps prevent gas leakage in the duct.

[0025] According to an optional embodiment of the present application, the purification module may include a purification core with a purification function and a purification bracket for holding the purification core. The purification bracket may be provided with at least one accommodating cavity for accommodating the purification core, and the number of the accommodating cavities is greater than or equal to the number of the purification cores.

[0026] Optionally, the purification bracket may be provided with a locking arm, and the locking arm is locked to the mounting bracket of the air duct cover so as to mount the purification module to the air duct cover.

[0027] According to an optional embodiment of the present application, the locking arm may include a first locking arm and a second locking arm. The mounting bracket may include a first mounting bracket and a second mounting bracket respectively coupled to the first locking arm and the second locking arm. Thus, the purification module can be reliably mounted to the air duct cover through convenient operation.

[0028] According to an optional embodiment of the present application, the first locking arm and the second locking arm may be located at opposite sides of the at least one accommodating cavity, respectively. The purification module may have a compact structure.

[0029] The first mounting bracket and the second mounting bracket may be located, for example, respectively on the outer sides of the first locking arm and the second locking arm facing away from the at least one accommodating cavity.

[0030] According to an optional embodiment of the present application, the first mounting bracket and the second mounting bracket may be formed into a U-shaped groove extending in a direction perpendicular to the main plane of the air duct cover. The first locking arm and the second locking arm may be inserted into the U-shaped grooves of the first mounting bracket and the second mounting bracket, respectively. The opening directions of the U-shaped grooves of the first mounting bracket and the second mounting bracket may be arranged facing each other. In the process of installing the purification module to the air duct cover or removing it from the air duct cover, the first mounting bracket and the second mounting bracket may guide and limit the movement of the first locking arm and the second locking arm. Thus, the installation and removal process of the purification module can be made more convenient. In particular, the heat insulation body (for example, including the heat insulation board) can be prevented from being damaged during the installation and removal of the purification module.

[0031] According to an optional embodiment of the present application, only one of the first mounting bracket and the second mounting bracket is provided with a recess at one end thereof facing the air duct, and the recess is open to the side facing away from the storage space. The purification bracket may be provided with a protrusion embedded in the recess. Thus, it is possible to ensure in a simple manner that the purification module is installed in the correct orientation.

[0032] According to an optional embodiment of the present application, the mounting bracket may be provided with a locking opening, and the locking arm may be provided with a hook. The hook extends into the locking opening in a direction parallel to the main plane of the air duct cover. Thus, the purification module can be installed through simple steps.

[0033] According to an optional embodiment of the present application, the purification bracket may be provided with a purification rear wall, which is located on the side of the purification core facing away from the air duct cover. For example, the purification rear wall may completely cover the purification core on the side of the purification core facing away from the air duct cover.

[0034] Optionally, the locking arm may be formed as a cantilever structure extending from the purification rear wall toward the storage space. Thus, the purification module can be installed by means of elastic deformation of the locking arm, which helps to reduce the difficulty of operation.

[0035] The mounting bracket can, for example, be against a side of the purification rear wall facing the purification core. Thus, the connection between the air duct cover and the purification module can be made more stable and reliable.

[0036] According to an optional embodiment of the present application, the first compartment wall of the compartment may be located on the side of the air duct body facing away from the storage space. The first compartment wall may be provided with a receiving recess for receiving the purification module, the receiving recess being opposite to the purification module and recessed in a direction away from the purification module. Thus, the air duct module can be prevented from being damaged.

[0037] According to an optional embodiment of the present application, the air duct module is detachably installed in the compartment, which is particularly advantageous for repair or maintenance of the air duct module and / or the purification module.

[0038] According to an optional embodiment of the present application, the purification module is detachably mounted to the air duct cover. When replacing the purification module or parts in the purification module, the purification module can be removed from the air duct cover without detaching the air duct body from the air duct cover. On the one hand, the difficulty of operation can be reduced. For example, an ordinary user can complete the replacement of the purification module or its parts without the intervention of professional staff. In addition, it can also avoid damage to the air duct module during the removal and reinstallation of the purification module.

[0039] According to a second aspect of the present application, an embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment, which is provided with a storage space for accommodating items to be cooled; a duct module for forming an air duct in the compartment, which includes a duct body for defining the air duct and a duct cover installed on one side of the duct body facing the storage space; and a purification module, which is at least partially located in the air duct to purify the gas flowing through the air duct. The duct body includes a heat insulation board at least partially located between the air duct and the duct cover, and at least a portion of the heat insulation board is located between the duct cover and the purification module along a direction perpendicular to the main plane of the duct cover.

[0040] According to a third aspect of the present application, an embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment, which is provided with a storage space for accommodating items to be cooled; a duct module for forming an air duct in the compartment, which includes a duct body for defining the air duct and a duct cover installed on one side of the duct body facing the storage space; and a purification module, which is at least partially located in the air duct to purify the gas flowing through the air duct. The duct body includes a duct back plate that defines the air duct at least on one side of the duct facing away from the duct cover, and the duct back plate is provided with a second through hole for installing the purification module to the duct cover.

[0041] According to a fourth aspect of the present application, an embodiment of the present application provides a method for manufacturing a refrigeration appliance, comprising: providing an air duct module, which includes an air duct main body for limiting the air duct and an air duct cover installed to the air duct main body; and installing a purification module to the air duct cover from a side of the air duct main body facing away from the air duct cover when the air duct main body and the air duct cover are assembled with each other, and the purification module is at least partially located in the air duct.

[0097] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the scope of protection of the present application.

[0098] First, for ease of understanding, let's go back to the description in the background technology section. The refrigeration appliances in the prior art have problems such as complex assembly and / or disassembly processes of purification modules, high requirements for operators, and easy damage to components during assembly and / or disassembly.

[0099] In view of at least one of the above technical problems or other possible technical problems, an exemplary embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment, which is provided with a storage space for accommodating items to be cooled; a duct module for forming an air duct in the compartment, which includes a duct body for defining the air duct and a duct cover installed on a side of the duct body facing the storage space; and a purification module, which is at least partially located in the duct to purify the gas flowing through the duct. The duct module is configured to allow the purification module to be installed to the duct cover from a side of the duct body facing away from the duct cover when the duct body and the duct cover are assembled with each other.

[0100] In view of at least one of the above technical problems or other possible technical problems, another exemplary embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment, which is provided with a storage space for accommodating items to be cooled; a duct module for forming an air duct in the compartment, which includes a duct body for defining the air duct and a duct cover installed on one side of the duct body facing the storage space; and a purification module, which is at least partially located in the air duct to purify the gas flowing through the air duct. The duct body includes a heat insulation board at least partially located between the air duct and the duct cover, and at least a portion of the heat insulation board is located between the duct cover and the purification module along a direction perpendicular to the main plane of the duct cover.

[0101] In view of at least one of the above technical problems or other possible technical problems, another exemplary embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment, which is provided with a storage space for accommodating items to be cooled; a duct module for forming an air duct in the compartment, which includes a duct body for defining the air duct and a duct cover installed on one side of the duct body facing the storage space; and a purification module, which is at least partially located in the air duct to purify the gas flowing through the air duct. The duct body includes a duct back plate that defines the air duct at least on a side of the duct facing away from the duct cover, and the duct back plate is provided with a second through hole for installing the purification module to the duct cover.

[0102] In order to better understand the present application, exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

[0103] Before starting the detailed description, it should be pointed out that the directional terms used in the description process refer to the normal use state of the refrigeration appliance for the convenience of description and should not be understood as an absolute limitation on the corresponding features. In some drawings, arrows are schematically shown to indicate the height direction H, the width direction W and the depth direction D that are perpendicular to each other.

[0104] Figure 1 A refrigeration appliance according to an exemplary embodiment of the present application is schematically shown in a cross-sectional view.

[0105] from Figure 1 As can be seen in the figure, the refrigeration appliance is provided with a compartment 10, which is provided with a storage space 110 for accommodating items to be cooled. The compartment 10 can be used as a cold storage room, for example. The items to be cooled can be stored in the storage space 110.

[0106] The refrigeration appliance is further provided with a duct module 2 for forming an air duct 120 in the compartment 10 and a purification module 3 at least partially located in the air duct 120 to purify the gas flowing through the air duct 120. The duct module 2 includes an air duct body 21 for defining the air duct 120 and an air duct cover 22 mounted to one side of the air duct body 21 facing the storage space 110. The air duct body 21 is perpendicular to the main flow direction of the air duct 120 (in Figure 1 The duct body 21 delimits the duct 120 in at least one lateral direction (schematically shown by dashed arrows in FIG. 1 ), in particular, the duct body 21 delimits the duct 120 in at least three lateral directions perpendicular to the main flow direction of the duct 120. As an example, the duct body 21 may delimit the duct 120 along the entire circumferential direction perpendicular to the main flow direction of the duct 120.

[0107] The air duct module 2 is configured to allow the purification module 3 to be installed to the air duct cover 22 from the side of the air duct body 21 facing away from the air duct cover 22 when the air duct body 21 and the air duct cover 22 are assembled with each other. Thus, the assembly and / or disassembly process of the air duct module 2 and the purification module 3 can be simplified.

[0108] Combine the following Figure 2 Further explanation. Figure 2 The air duct module 2 and the purification module 3 of a refrigeration appliance according to an exemplary embodiment of the present invention are schematically shown.

[0109] exist Figure 2 In the embodiment, the air duct body 21 and the air duct cover 22 are in a mutually assembled state, wherein the air duct body 21 and the air duct cover 22 are connected to each other in a non-movable manner relative to each other. The purification module 3 can be installed to the air duct cover 22 from the side of the air duct body 21 facing away from the air duct cover 22. For example, when assembling a refrigeration appliance, the air duct module 2 can be provided as an assembled whole, for example, provided by a manufacturer. The assembler of the refrigeration appliance can directly operate the assembled air duct module 2 without performing the assembly operation of the air duct body 21 and the air duct cover 22. This can not only reduce the difficulty of the assembly operation, but also prevent the air duct module 2 from being damaged during the assembly process.

[0110] For example, the air duct body 21 may be provided with a mounting hole 210. The purification module 3 may extend into the mounting hole 210 or pass through the mounting hole 210 from the side of the air duct body 21 facing away from the air duct cover 22 so as to be installed to the air duct cover 22. Alternatively or additionally, the air duct cover 22 may be provided with a mounting bracket 221, and the purification module 3 can be installed to the air duct cover 22 through the mounting bracket 221. The mounting bracket 221 may extend into the mounting hole 210. The mounting hole 210 may especially completely penetrate the air duct body 21 in a direction perpendicular to the air duct cover 22. By providing the mounting hole 210 that completely penetrates the air duct body 21 at the position where the purification module 3 is to be installed, the purification module 3 can be installed to the desired position with simple operating steps.

[0111] Optionally, the purification module 3 can be configured to be installed to the duct cover 22 from the side of the duct body 21 facing away from the duct cover 22 along a direction D1 perpendicular to the main plane of the duct cover 22. This helps to simplify the installation process of the purification module 3.

[0112] It is particularly advantageous that the purification module 3 is detachably mounted to the air duct cover 22. When replacing the purification module 3 or parts in the purification module 3, the purification module 3 can be directly removed from the air duct module 2 without separating the air duct body 21 from the air duct cover 22.

[0113] When the air duct body 21 and the air duct cover 22 remain in the assembled state, the purification module 3 can be disassembled and installed. This is particularly advantageous for the repair or maintenance of the purification module 3. On the one hand, the difficulty of operation can be reduced. For example, an ordinary user can replace the purification module 3 or its parts without the intervention of professional staff. In addition, it can also avoid damage to the air duct module 2 during the disassembly and reinstallation of the purification module 3.

[0114] Figure 3 The installation of the air duct module 2 and the purification module 3 to the compartment 10 in an exemplary embodiment according to the present invention is schematically shown.

[0115] like Figure 3 As shown, the compartment 10 can be surrounded by the inner liner 11 of the refrigerating appliance. After the purification module 3 is installed to the air duct module 2, the air duct module 2 with the purification module 3 can be installed in the compartment 10.

[0116] It is particularly advantageous that the air duct module 2 is detachably installed in the compartment 10. This is particularly advantageous for repair or maintenance of the air duct module 2 and / or the purification module 3.

[0117] See also Figure 1 , the air duct module 2 can be arranged at the rear of the compartment 10, for example. The air duct 120 can be located between the rear wall of the compartment 10 and the air duct cover 22, and the storage space 110 is located in front of the air duct cover 22. The cooling gas can flow from bottom to top in the air duct 120, for example. In this article, the air duct 120 can particularly refer to the section of the air duct 120 where the purification module 3 is located.

[0118] The purification module 3 can purify the gas flowing through the air duct 120. In this article, "purification" may include functions such as sterilization, disinfection and / or deodorization. For example, the purification module 3 may produce a bactericidal substance to kill bacteria, or be configured as a filter for filtering air. Exemplarily, the purification module 3 may include activated carbon, which reduces the odor in the gas by physical adsorption. Alternatively or additionally, the purification module 3 may include an ion generating module and / or an ozone generating module, etc. In this embodiment, the purification module 3 is arranged behind the air duct cover 22, so that it is shielded by the air duct cover 22 and is not exposed to the storage space 110. The air duct cover 22 does not need to be provided with an opening in front of the purification module 3, so that it can have a flat outer surface in the front (i.e., on the side facing the storage space 110).

[0119] In another embodiment, the air duct module 2 may also be arranged at other positions of the compartment 10, such as the top of the compartment 10. Accordingly, the air duct 120 may be located between the top wall of the compartment 10 and the air duct cover 22, and the storage space 110 may be located below the air duct cover 22. The purification module 3 may be arranged above the air duct cover 22.

[0120] exist Figure 1 In the illustrated embodiment, the air duct 120 can be used to supply cooling gas to the storage space 110 of the compartment 10. Optionally, the air duct 120 can also be used to supply cooling gas to another compartment outside the compartment 10. For example, the air duct module 2 can be arranged in the freezer compartment of the refrigeration appliance and used to supply cooling gas to the cold storage compartment of the refrigeration appliance. Alternatively, it is also feasible that the air duct 120 is used as a return air duct. In this case, the air duct 120 can be used to guide the gas in the storage space 110 to the refrigeration device (e.g., evaporator) of the refrigeration appliance.

[0121] from Figure 1 It can be seen that the refrigeration appliance may also include a freezer compartment located below the refrigerator compartment. It will be appreciated by those skilled in the art that the compartment 10 may also be used as a freezer compartment. In this embodiment, the refrigeration appliance may be implemented as a combined refrigerator having a refrigerator compartment and a freezer compartment, for example. It will be appreciated by those skilled in the art that the present invention is also applicable to other types of refrigerators, such as a separate refrigerator or freezer. In addition, the present invention may also be applied to other refrigeration appliances other than refrigerators, such as a wine cabinet, as required. The present invention is particularly applicable to household refrigeration appliances.

[0122] Figure 4 A compartment 10 of a refrigeration appliance according to an exemplary embodiment of the present invention is schematically shown in a cross-sectional view. Figure 5 Schematically shows Figure 4 A partial enlarged view of the circled portion.

[0123] like Figure 4 As shown, the compartment 10 can be surrounded by the inner liner 11. The air duct module 2 is illustratively arranged in front of the rear wall of the inner liner 11. Therefore, the storage space 110 is located in front of the air duct cover 22, and the air duct 120 and the air duct body 21 are located behind the air duct cover 22.

[0124] Combination Figure 5 It can be seen that the air duct body 21 may include a heat insulation board 211 at least partially located between the air duct 120 and the air duct cover 22. The heat insulation board 211 may be made of a heat insulation material, such as polystyrene foam (EPS).

[0125] The heat insulation board 211 may be provided with a first through hole 2111. The mounting hole 210 described above may include or be formed as the first through hole 2111.

[0126] Optionally, the purification module 3 may extend into the first through hole 2111 from the side of the heat insulation board 211 facing away from the air duct cover 22 so as to be installed on the air duct cover 22. Figure 5 As shown by the solid arrow in , the purification module 3 can be installed to the air duct cover 22 along the direction D1.

[0127] Here, the air duct cover 22 is provided with a mounting bracket 221 on one side facing the air duct 120, and the purification module 3 can be mounted to the air duct cover 22 by means of the mounting bracket 221. The mounting bracket 221 can, for example, extend into the first through hole 2111. The air duct cover 22 can, for example, be formed as a single integral component. In other words, the mounting bracket 221 can form an integral part of the air duct cover 22. Optionally, the air duct cover 22 can be formed as a plastic part, such as an injection molded part. Thus, the air duct cover 22 that can stably and reliably carry the purification module 3 can be formed in a manner that is easy to manufacture.

[0128] In other embodiments, it is also feasible to install the purification module 3 to the air duct cover 22 in other ways, such as magnetic attraction or threaded connection.

[0129] See also Figure 5 The purification module 3 can be installed from the side of the heat insulation board 211 facing away from the air duct cover 22 to the back side of the air duct cover 22 facing away from the storage space 110, and the purification module 3 can be completely shielded by the air duct cover 22 in the front and will not be exposed to the storage space 110. The air duct cover 22 does not need to be provided with an opening in front of the purification module 3, so that it can have a flat outer surface in the front.

[0130] As an example, the purification module 3 may include a purification core 31 having a purification function and a purification bracket 32 ​​for holding the purification core 31. The purification core 31 may include, for example, a filter core, an ion generator and / or an ozone generator. The purification bracket 32 ​​may be coupled to the mounting bracket 221. Figure 5 As shown by the dashed arrows in FIG. 1 , the cooling gas may flow from bottom to top in the air duct 120. The cooling gas flowing through the purification module 3 may be purified.

[0131] In other embodiments, it is also possible for the purification module 3 to have other configurations.

[0132] Figure 6 An air duct module 2 of a refrigeration appliance according to an exemplary embodiment of the present invention is schematically shown. Figure 7 The air duct module 2 and the purification module 3 of a refrigeration appliance according to an exemplary embodiment of the present invention are schematically shown.

[0133] Air duct module 2 Figure 6 2 is shown in an exploded view, wherein the air duct body 21 may include a heat insulation board 211 , which has not yet been assembled to the air duct cover 22 .

[0134] For example, the heat insulation board 211 may be provided with a channel for forming the air duct 120 on a side facing away from the air duct cover 22 .

[0135] The air duct cover 22 may be provided with a mounting bracket 221 on a side facing the air duct 120. The heat insulation board 211 may be provided with a first through hole 2111 at a position opposite to the mounting bracket 221 in a direction perpendicular to the main plane of the air duct cover 22. Figure 6 In the illustrated embodiment, the air duct cover 22 is provided with a pair of mounting brackets 221. The heat insulation board 211 is optionally provided with a pair of first through holes 2111 corresponding to the mounting brackets 221.

[0136] Air duct module 2 Figure 7 The heat shield 211 can be directly connected to the air duct cover 22. Figure 6 and Figure 7 It can be seen that the mounting bracket 221 can extend into the first through hole 2111. The mounting bracket 221 can especially extend through and beyond the first through hole 2111 (i.e., the mounting hole 210). In this case, the purification module 3 can be mounted to the air duct cover 22 in the direction D1 perpendicular to the main plane of the air duct cover 22. Alternatively, the purification module 3 can also be mounted to the mounting bracket 221 in a direction parallel to the air duct cover 22. When the mounting bracket 221 passes through and exceeds the first through hole 2111, the purification module 3 can be mounted to the air duct cover 22 by means of the mounting bracket 221 without extending into the first through hole 2111. Thus, the first through hole 2111 can be allowed to have a smaller size. In addition, the installation direction of the purification module 3 can be made to have more options.

[0137] In another embodiment, the mounting bracket 221 may terminate in the first through hole 2111 in a direction facing away from the storage space 110 (ie, in a backward direction). That is, the mounting bracket 221 does not extend from the first through hole 2111.

[0138] Figure 8 Schematically shows Figure 7 A partial enlarged view of the framed portion. Fig. 9 Schematically shows Figure 8 Rear view of the portion shown.

[0139] from Figure 8 It can be seen more clearly that the mounting bracket 221 includes a first mounting bracket 2211 and a second mounting bracket 2212 , which extend through the two first through holes 2111 of the heat insulation board 211 respectively.

[0140] Combination Figure 7 and Figure 8It can be seen that, along the projection direction perpendicular to the main plane of the air duct cover 22, the projection of the first through hole 2111 may be smaller than the projection of the portion of the purification module 3 located in the air duct 120. In other words, when viewed along the main plane perpendicular to the air duct cover 22, the first through hole 2111 has a significantly smaller size than the portion of the purification module 3 located in the air duct 120. The smaller first through hole 2111 can effectively prevent condensation from occurring at the position corresponding to the purification module 3 on the side of the air duct cover 22 facing the storage space 110.

[0141] Back to Figure 5 , it can be seen that at least a portion of the heat insulation board 211 can be projected onto the purification core 31 of the purification module 3 along a direction perpendicular to the main plane of the air duct cover 22. In other words, at least a portion of the heat insulation board 211 is located between the air duct cover 22 and the purification module 3 along a direction perpendicular to the main plane of the air duct cover 22. Obviously, at least a portion of the heat insulation board 211 is an integral part of the heat insulation board 211, rather than a separate component. Thus, at least a portion of the heat insulation board 211 can be used to effectively separate the air duct cover 22 from the purification core 31 of the purification module 3 in an insulating manner. Therefore, there is no need to additionally provide a heat insulation component in the purification module 3, thereby simplifying the structure and significantly reducing costs. This configuration can prevent condensation from occurring on the air duct cover 22 at a position corresponding to the purification module 3 on the side facing the storage space 110, and can also simplify the structure and simplify the installation process.

[0142] The purification core 31 of the purification module 3 can be projected onto the heat insulation board 211 in a direction perpendicular to the main plane of the air duct cover 22. Thus, the heat insulation board 211 can be effectively used to prevent condensation from occurring at a position corresponding to the purification module 3 on the side of the air duct cover 22 facing the storage space 110.

[0143] See also Figure 6 and Figure 8 The heat insulation board 211 may be provided with a receiving recess 2112 at a position opposite to the purification module 3 in a direction perpendicular to the main plane of the air duct cover 22. The receiving recess 2112 is recessed in a direction away from the purification module 3 (here, recessed forward). The bottom surface of the receiving recess 2112 is opposite to the purification module 3.

[0144] like Fig. 9 As shown, the receiving recess 2112 may be located between the pair of first through holes 2111. The pair of first through holes 2111 may define boundaries of the receiving recess 2112 on opposite sides.

[0145] In an exemplary embodiment of the present invention, the heat insulation board 211 may be provided with a convex column 2113 located in the air duct 120, see Figure 5The boss 2113 may penetrate the air duct 120 in a direction perpendicular to the main plane of the air duct cover 22. Optionally, the boss 2113 may be supported on the inner liner 11. Figure 8 and Fig. 9 As shown, the boss 2113 may be arranged adjacent to the first through hole 2111. Thus, the structural strength may be improved.

[0146] The boss 2113 can be arranged successively with the first through hole 2111 in particular along the main flow direction of the air duct 120. Thus, the obstruction of the boss 2113 and the purification module 3 to the gas flow can be reduced. The boss 2113 and the first through hole 2111 are arranged successively, including the case where the boss 2113 is upstream of the first through hole 2111 and the case where the boss 2113 is downstream of the first through hole 2111. For example, two bosses 2113 can be respectively arranged directly below the two first through holes 2111. The boss 2113 and the purification module 3 have less obstruction to the cooling gas flowing from bottom to top.

[0147] Fig.10 A purification module 3 of a refrigeration appliance according to an exemplary embodiment of the present invention is schematically shown.

[0148] like Fig.10 As shown, the purification module 3 may include at least one purification core 31 and a purification bracket 32. The purification bracket 32 ​​may be provided with at least one accommodating cavity 321 for accommodating the purification core 31. The number of the accommodating cavities 321 may be greater than or equal to the number of the purification cores 31. For example, the purification bracket 32 ​​may be provided with three accommodating cavities 321. The purification core 31 may be arranged in two of the three accommodating cavities 321 as needed. The remaining accommodating cavity 321 may be empty. Thus, a suitable number of purification cores 31 may be installed as needed.

[0149] The accommodating chamber 321 may be arranged along the main flow direction of the air duct 120 (eg Fig.10 The air duct 120 is connected as shown by the dotted arrow in the figure, so that the cooling gas in the air duct 120 can fully contact the purification core 31.

[0150] Optionally, the purification bracket 32 ​​may be provided with a locking arm 322 . The locking arm 322 is used to be locked to the mounting bracket 221 of the air duct cover 22 so as to mount the purification module 3 to the air duct cover 22 .

[0151] The locking arm 322 may include, for example, a first locking arm 3221 and a second locking arm 3222. The first locking arm 3221 and the second locking arm 3222 may be respectively coupled to the first mounting bracket 2211 and the second mounting bracket 2212. Thus, the air duct cover 22 may be reliably installed with convenient operation.

[0152] The first locking arm 3221 and the second locking arm 3222 can be located at opposite sides of the at least one accommodating cavity 321. The purification module 3 can have a compact structure, thereby reducing the volume occupied by the air duct 120 and the resistance to the gas in the air duct 120.

[0153] The purification bracket 32 ​​may also be provided with a purification rear wall 323, for example, which is located on the side of the purification core 31 facing away from the air duct cover 22. Optionally, the purification rear wall 323 may completely cover the purification core 31 on the side of the purification core 31 facing away from the air duct cover 22.

[0154] The locking arm 322 can be formed as a cantilever structure extending from the purification rear wall 323 toward the storage space 110 . Thus, the purification module 3 can be installed by means of the elastic deformation of the locking arm 322 .

[0155] like Figure 8 and Fig. 9 As shown, the first mounting bracket 2211 and the second mounting bracket 2212 can be formed into a U-shaped groove extending in a direction perpendicular to the main plane of the air duct cover 22. In other words, in a cross section parallel to the air duct cover 22, the first mounting bracket 2211 and the second mounting bracket 2212 have a U-shaped cross section. The first locking arm 3221 and the second locking arm 3222 can be inserted into the U-shaped groove of the first mounting bracket 2211 and the second mounting bracket 2212. The opening directions of the U-shaped grooves of the first mounting bracket 2211 and the second mounting bracket 2212 are arranged facing each other. In the process of installing the purification module 3 to the air duct cover 22 or removing it from the air duct cover 22, the first mounting bracket 2211 and the second mounting bracket 2212 can guide and limit the movement of the first locking arm 3221 and the second locking arm 3222. As a result, the installation and removal process of the purification module 3 can be made more convenient. In particular, the heat insulation board 211 can be prevented from being damaged during the installation and removal process of the purification module 3.

[0156] In an exemplary embodiment of the present invention, the mounting bracket 221 may be provided with a locking opening 2213, and the locking arm 322 may be provided with a hook portion 3223, see Figure 8 and Fig.10 The hook portion 3223 can extend into the locking opening 2213 in a direction parallel to the main plane of the air duct cover 22. Thus, the purification module 3 can be installed through simple steps.

[0157] Figure 8 It is also shown that only one of the first mounting bracket 2211 and the second mounting bracket 2212 is provided with a recess 2214 at its end facing the air duct 120, and the recess 2214 is open to the side facing away from the storage space 110. For example, only the first mounting bracket 2211 is provided with a recess 2214, while the second mounting bracket 2212 is not provided with a recess 2214 at the corresponding position. Fig.10 As shown, the purification bracket 32 ​​may be provided with a protrusion 324 for embedding into the recess 2214. Thus, it is possible to ensure that the purification module 3 is installed in the correct orientation in a simple manner. If the operator attempts to install the purification module 3 upside down to the air duct cover 22, the protrusion 324 of the purification bracket 32 ​​will interfere with the second mounting bracket 2212 without the recess 2214, thereby preventing the upside-down purification module 3 from being installed to the air duct cover 22. Therefore, even if it is difficult for the operator to visually observe the mounting bracket 221 and the locking arm 322 during the installation process, it is possible to ensure that the purification bracket 32 ​​is correctly installed.

[0158] Fig.11 A compartment 10 of a refrigeration appliance according to an exemplary embodiment of the present invention is schematically shown in a cross-sectional view. Fig.12 Schematically shows Fig.11 A partial enlarged view of the framed portion. Fig.13 Schematically shows Fig.12 A partial enlarged view of the circled portion.

[0159] Fig.11 It is shown that the air duct module 2 and the purification module 3 are arranged in the inner tank 11 , for example, arranged at the first compartment wall 101 .

[0160] from Fig.12 and Fig.13 It can be seen more clearly that the first mounting bracket 2211 and the second mounting bracket 2212 extend through and beyond the two first through holes 2111 respectively. The first locking arm 3221 and the second locking arm 3222 are respectively engaged to the first mounting bracket 2211 and the second mounting bracket 2212. The first locking arm 3221 and the second locking arm 3222 do not need to extend into the first through hole 2111.

[0161] The first mounting bracket 2211 and / or the second mounting bracket 2212 may abut against the side of the purification rear wall 323 facing the purification core 31. Thus, the connection between the air duct cover 22 and the purification module 3 may be made more stable and reliable.

[0162] The first mounting bracket 2211 and the second mounting bracket 2212 may be located, for example, on the outer sides of the first locking arm 3221 and the second locking arm 3222, respectively, facing away from the at least one accommodating cavity 321. The hooks 3223 of the first locking arm 3221 and the second locking arm 3222 may protrude in opposite directions. The hooks 3223 may extend into the locking opening 2213 in a direction parallel to the main plane of the air duct cover 22. Through the hooks 3223, the purification module 3 may be limited at least in a direction perpendicular to the main plane of the air duct cover 22.

[0163] Only the first mounting bracket 2211 of the first mounting bracket 2212 has a recess 2214 at one end thereof facing the air duct 120, and the recess 2214 is open to the side facing away from the storage space 110. The purification bracket 32 ​​may have a protrusion 324 embedded in the recess 2214 beside the first locking arm 3221.

[0164] In an exemplary embodiment of the present invention, the first compartment wall 101 of the compartment 10 may be located on the side of the air duct body 21 facing away from the storage space 110. The first compartment wall 101 may be provided with a receiving recess 1011 for receiving the purification module 3, see Figure 5 , Fig.12 and Fig.13 The accommodating recess 1011 may be opposite to the purification module 3 and recessed in a direction away from the purification module 3 (rearward in this case). Thus, the air duct module 2 may be prevented from being damaged.

[0165] Fig.14 An air duct module 2 of a refrigeration appliance according to an exemplary embodiment of the present invention is schematically shown. Fig.15 The air duct module 2 and the purification module 3 of a refrigeration appliance according to an exemplary embodiment of the present invention are schematically shown.

[0166] Air duct module 2 Fig.14 2 is shown in an exploded view. In this embodiment, the air duct body 21 of the air duct module 2 may include a heat insulation board 211 and an air duct back plate 212. The air duct back plate 212 limits the air duct 120 at least on the side of the air duct 120 facing away from the air duct cover 22. The air duct body 21 may, for example, limit the air duct 120 at least in two opposite directions along the main plane perpendicular to the air duct cover by the heat insulation board 211 and the air duct back plate 212. The air duct back plate 212 may be made of a heat insulating material. The air duct back plate 212 may also be made of other materials, such as plastic.

[0167] like Fig.14 As shown, the air duct back plate 212 may be provided with a second through hole 2121. Fig.15 It can be seen that the purification module 3 can pass through the second through hole 2121 or extend into the second through hole 2121 from the side of the heat insulation board 211 facing away from the air duct cover 22, so as to be installed on the air duct cover 22. The second through hole 2121 can be arranged at a position corresponding to the purification module 3 in a direction perpendicular to the main plane of the air duct cover 22.

[0168] In this embodiment, the air duct cover 22 and the heat shield 211 can be constructed in the same or similar manner as described above. For example, the air duct cover 22 can be provided with a mounting bracket 221, and the purification module 3 can be mounted to the air duct cover 22 through the mounting bracket 221. The heat shield 211 can be provided with a first through hole 2111, and the purification module 3 and / or the mounting bracket 221 can extend into the first through hole 2111. The mounting hole 210 of the air duct body 21 may include a first through hole 2111 and a second through hole 2121. The first through hole 2111 can be arranged to align with the second through hole 2121.

[0169] The air duct back plate 212 and the heat insulation board 211 may also have other variations. For example, the heat insulation board 211 may not be provided with a channel, but may be formed into a substantially flat plate shape. The air duct back plate 212 may be provided with a channel for forming the air duct 120 on a side facing the air duct 120.

[0170] In another embodiment, the air duct body 21 may not include the heat insulation board 211 between the air duct 120 and the air duct cover 22. The air duct 120 may be bounded by the air duct cover 22 in the direction toward the storage space 110 and by the air duct back plate 212 on the side opposite to the air duct cover 22.

[0171] Air duct module 2 Fig.15 2 is shown in an assembled state. The air duct cover 22 and the air duct body 21 (here including the heat insulation board 211 and the air duct back plate 212) are in a mutually assembled state, wherein the air duct cover 22, the heat insulation board 211 and the air duct back plate 212 are connected to each other so as not to move relative to each other. The purification module 3 can be mounted to the air duct cover 22 from the side of the air duct body 21 facing away from the air duct cover 22.

[0172] The purification module 3 may be coupled to the mounting bracket 221 via the second through hole 2121 along a direction D1 perpendicular to the main plane of the air duct cover 22 , thereby being mounted to the air duct cover 22 .

[0173] Fig.16 It is schematically shown that in an exemplary embodiment according to the present invention, the purification module 3 is installed to the air duct module 2. In this state, the purification module 3 can be embedded in the air duct module 2, and only the purification rear wall 323 is exposed to the outside.

[0174] like Fig.16 As shown, the refrigeration appliance may include, for example, a covering film 4. The covering film 4 may be attached to the air duct back plate 212 at a side of the air duct back plate 212 facing away from the air duct 120 and cover the second through hole 2121 and / or the purification module 3.

[0175] Fig.17 It is schematically shown that in an exemplary embodiment according to the present invention, the cover film 4 is attached to the air duct back plate 212 .

[0176] like Fig.17 As shown, the covering film 4 can close the gap between the purification module 3 and the air duct back plate 212 from the rear. The covering film 4 can especially completely cover the purification rear wall 323 (at Fig.17 The coverage of the covering film 4 may be slightly larger than the purified rear wall 323. The area of ​​the covering film 4 is in particular not greater than 4 times the area of ​​the purified rear wall 323.

[0177] For example, the covering film 4 may be adhered to the air duct back plate 212 .

[0178] Fig.18 With Figure 5 A similar figure schematically shows another exemplary embodiment according to the invention.

[0179] In this embodiment, the refrigeration appliance may have Figure 5 The refrigeration appliance in the embodiment shown in the figure has a similar structure. The difference is at least that Fig.18 In the refrigeration appliance shown, an air duct back plate 212 and a covering film 4 are also provided.

[0180] like Fig.18 As shown, the purification module 3 can be installed to the air duct cover 22 through the second through hole 2121 along a direction D1 perpendicular to the main plane of the air duct cover 22. The purification module 3 can especially close the second through hole 2121. Thus, the gas in the air duct 120 can be prevented from leaking through the second through hole 2121.

[0181] The purification module 3 may be provided with a purification rear wall 323, for example. The purification rear wall 323 may be located on the side of the air duct back plate 212 facing away from the air duct 120 and completely close the second through hole 2121. The purification rear wall 323 may be attached to the air duct back plate 212 on the side of the air duct back plate 212 facing away from the air duct 120. This further helps to prevent gas leakage in the air duct 120.

[0182] Optionally, the covering film 4 may be attached to the duct back plate 212 at the side of the duct back plate 212 facing away from the duct 120 and cover the purification module 3. Any gap between the purification module 3 and the duct back plate 212 may be closed by the covering film 4.

[0183] Fig.18It is also shown that the first compartment wall 101 of the compartment 10 is located on the side of the air duct body 21 facing away from the storage space 110, and is provided with a receiving recess 1011 for receiving the purification module 3. The receiving recess 1011 may be recessed backward. By using the receiving recess 1011 to receive the purification module 3, the purification module 3 can be prevented from squeezing the air duct body 21, especially squeezing the air duct back plate 212. With the aid of the receiving recess 1011, the purification module 3 will not abut against the first compartment wall 101. Thus, the air duct module 2 can be prevented from being damaged. For example, when the air duct module 2 is pushed toward the first compartment wall 101, the air duct back plate 212 can be prevented from being squeezed and damaged by the purification rear wall 323.

[0184] Fig.18 It is also shown that the heat insulation board 211 may be provided with a boss 2113 located in the air duct 120. The boss 2113 may penetrate the air duct 120 in a direction perpendicular to the main plane of the air duct cover 22. The boss 2113 may be supported on the air duct back plate 212, for example. The boss 2113 may be arranged in particular adjacent to the first through hole 2111. When installing and removing the purification module 3, the boss 2113 may prevent the air duct module 2 from being damaged.

[0185] Fig.19 An assembly method for a refrigeration appliance according to an exemplary embodiment of the present invention is schematically illustrated.

[0186] According to the embodiment of the present invention, after the air duct body 21 and the air duct cover are assembled to form the air duct module 2 , the purification module 3 is installed to the air duct module 2 from the air duct body 21 side.

[0187] like Fig.19 As shown, the assembling method may include the following steps S11 to S15.

[0188] In step S11 , a compartment 10 is provided. Step S11 may include providing a housing 1 having the compartment 10 .

[0189] In step S12, a duct module 2 is provided, and the duct module 2 includes a duct body 21 and a duct cover 22 that are assembled with each other. The duct module 2 can be provided as an assembled whole, for example, provided by a manufacturer of the duct module 2. The assembler of the refrigeration appliance can directly operate the assembled duct module 2 without performing the assembly operation of the duct body 21 and the duct cover 22.

[0190] In step S13, a purification module 3 is provided. The purification module 3 and the air duct module 2 may be provided as separate components by different manufacturers, for example.

[0191] In step S14 , the purification module 3 is mounted to the air duct module 2 in a state where the air duct body 21 and the air duct cover 22 are assembled with each other.

[0192] In step S15 , the air duct module 2 with the purification module 3 is installed in the compartment 10 .

[0193] Fig. 20 A disassembly method of a refrigeration appliance according to an exemplary embodiment of the present invention is schematically illustrated.

[0194] like Fig. 20 As shown, the disassembly method may include the following steps S21 and S22.

[0195] In step S21 , the air duct module 2 with the purification module 3 is removed from the housing 1 .

[0196] In step S22, the purification module 3 is disassembled from the air duct module 2 in a state where the air duct body 21 and the air duct cover 22 are assembled with each other.
