[0002] With the development of industrial automation, the automation of refrigerator production has become an industry trend. As a refrigeration component of refrigerators, the level of automation in the assembly of the air duct module directly affects the overall production efficiency. In automated assembly, the robotic arm needs to stably grasp and position multiple parts in the air duct module. This requires that each part in the air duct module be designed with a dedicated picking and matching structure to provide space for the robotic arm's operation.

[0003] However, the air duct modules in related technologies have not fully considered this requirement in their design. They generally lack a picking and fitting part or a clearance structure specifically designed for robotic arms, making it difficult for robotic arms to achieve stable and efficient grasping and transfer, and making it difficult to realize the intelligent production of air duct modules.

[0024] With the development of industrial automation, the automation of refrigerator production has become an industry trend. As a refrigeration component of refrigerators, the level of automation in the assembly of the refrigeration duct directly affects the overall production efficiency. In automated assembly, the robotic arm needs to stably grasp and position multiple parts in the refrigeration component. This requires that each part in the refrigeration component be designed with a dedicated picking and matching structure to provide space for the robotic arm's operation.

[0025] However, the refrigeration components in related technologies have not fully considered this requirement in their design, and generally lack a picking and mating part or clearance structure specifically designed for robotic arms. This makes it difficult for robotic arms to achieve stable and efficient grasping and transfer, and makes it difficult to realize the intelligent production of refrigeration components.

[0026] In view of this, this application proposes an air duct module and a refrigerator. Figures 1 to 9 These are some embodiments of this application.

[0027] In some embodiments of this application, the air duct module 100 is disposed in the inner liner of the refrigerator; wherein, the air duct module being disposed in the inner liner of the refrigerator can effectively reduce the thickness of the refrigerator compared to the installation method in the related art where the cooling air duct is disposed at the rear of the refrigerator and outside the inner liner.

[0028] When the air duct module 100 is installed in the inner liner of the refrigerator, it can divide the inner liner of the refrigerator into multiple compartments, or it can be installed as a whole on the side wall of the inner liner of the refrigerator, serving only the cooling function without dividing the space of the inner liner.

[0029] Specifically, in one embodiment of this application, the air duct module 100 divides the inner liner into multiple compartments; wherein, the air duct module 100 divides the inner liner into multiple compartments, so that multiple cavities for storing items can be formed inside the inner liner, thereby providing storage for different types of items.

[0030] Please see Figures 1 to 2 In some embodiments of this application, the air duct module 100 includes a housing 1, which includes a shell 11 and a cover 12. The shell 11 and the cover 12 enclose a mounting cavity 2 for accommodating the cooling components in the air duct module 100. The cooling components include, but are not limited to, the fan assembly 5 and the evaporator.

[0031] The split-type structure of the outer shell 1 facilitates the assembly of the cooling components into the mounting cavity 2 by automated tooling. For example, after a robotic arm assembles the cooling components into the shell 11, the cover 12 is then assembled at the opening of the shell 11.

[0032] The assembly method of the shell 11 and the cover 12 is not limited. It can be snap-fit, screw-fit, or welding, or a combination of multiple assembly methods.

[0033] Please see Figures 3 to 4In some embodiments of this application, a mounting groove 3 is formed on the inner side of the housing 11, and a plurality of grooves 4 are located on the periphery of the mounting groove 3 and communicate with the mounting groove 3; the fan assembly 5 includes a fan 51, the fan 51 includes a fan body 511 and a mounting part 512, the fan body 511 cooperates with the mounting groove 3, and the mounting part 512 is located on the periphery of the fan body 511 and cooperates with the grooves 4; wherein, the mounting groove 3 can provide installation space for the fan body 511, and the grooves 4 can provide installation space for the mounting part 512. When the robot arm clamps the fan 51 for installation, the fan body 511 can be aligned with the mounting groove 3 and the mounting part 512 can be aligned with the groove 4 to realize the assembly of the fan 51 in the mounting cavity 2.

[0034] Of course, in order to provide a clearance structure within the mounting cavity 2 to allow the robotic arm to pass during the installation of the fan 51, in some embodiments of this application, the plurality of grooves 4 include a positioning groove 41 that mates with the mounting part 512 and at least two clearance grooves 42; that is, the positioning groove 41 is used to mate with the mounting part 512 to provide it with installation positioning, while the clearance groove 42 is used for the robotic arm that holds the fan 51 to extend into and pass through, thereby ensuring that the robotic arm can achieve automated operation and accurately assemble the fan 51 into the mounting cavity 2.

[0035] In summary, the technical solution of this application optimizes the structure of the air duct module 100 to achieve automated installation of the air duct module 100. The outer shell 1 is a split type, with the shell 11 and the cover 12 forming the mounting cavity 2, which facilitates the assembly of the fan assembly 5 inside the air duct module 100; the mounting groove 3 and multiple recesses 4 located around the mounting groove 3 can respectively accommodate the fan body 511 and the mounting part 512 of the fan 51; wherein, the recesses 4 are further divided into positioning recesses 41 for mounting the mounting part 512 and avoidance recesses 42 for the robot to avoid, thereby forming a structural layout in the air duct module 100 suitable for automated operation of the robot.

[0036] In other words, the air duct module described in this application embodiment not only enables the automated installation of the fan 51, but also provides the necessary clearance for the gripping operation of the robotic arm, which can effectively solve the problem that the air duct module in related technologies is difficult to automate due to the lack of a dedicated picking and matching structure.

[0037] In the above embodiments, the number of clearance grooves 42 can be designed according to the number of grippers of the robot arm. Since the robot arm clamps and fixes the fan 51, in the above embodiments, there are at least two oppositely arranged clearance grooves 42 to allow the robot arm to avoid obstacles.

[0038] In one specific embodiment of this application, the robotic arm uses a three-jaw gripper to hold the fan 51. Therefore, three clearance grooves 42 are provided at the periphery of the mounting groove 3 to avoid different grippers on the robotic arm.

[0039] Based on this, in some embodiments of this application, the number of grooves 4 is set to six, three of which are positioning grooves 41 and the other three are clearance grooves 42. The three positioning grooves 41 and the three clearance grooves 42 are arranged around the mounting groove 3 and arranged in sequence. This ensures that the fan 51 can be fixed firmly while avoiding the robot arm from obstructing the installation of the mounting part 512 at the positioning groove 41.

[0040] The mounting method of the mounting part 512 at the positioning groove 41 is not limited; it can be snap-fit, screw-fit, etc.

[0041] Specifically, the mounting part 512 is fixed to the positioning groove 41 by bolts.

[0042] It should be further explained that in the above embodiment, the housing 11 and the cover 12 enclose and form the mounting cavity 2; the housing 11 may be provided with an open mounting cavity 2 and the cover 12 may cover the mounting cavity 2, or both the housing 11 and the cover 12 may be provided with portions of the mounting cavity 2, so that a complete mounting cavity 2 is formed after the housing 11 and the cover 12 are enclosed.

[0043] In some embodiments of this application, the fan assembly 5 further includes a volute 52, which is disposed in the mounting cavity 2 to define the fan mounting cavity together with the housing 11. The fan 51 is disposed in the fan mounting cavity. The volute 52 has an air inlet end and an air outlet end, both of which are connected to the fan mounting cavity. The fan can guide airflow from the air inlet end into the fan mounting cavity and then out from the air outlet end to achieve the delivery of cold air.

[0044] In some embodiments of this application, the fan assembly 5 further includes an air outlet duct and an air outlet 17 connected to the air outlet duct. The air outlet end of the volute 52 is connected to the air outlet duct to guide airflow into the air outlet duct and discharge it from the air outlet 17 into the inner liner environment, thereby realizing the refrigeration function of the refrigerator.

[0045] Furthermore, in some embodiments of this application, the volute 52 is provided with at least two first pick-up mating parts 6; that is, the volute 52 can be picked up by an automated pick-up tooling through the two first pick-up mating parts 6, thereby realizing the automated assembly of the volute 52.

[0046] The automatic pickup fixture and the two first pickup mating parts 6 can be fixed by vacuum adsorption or by clamping, and there is no restriction here.

[0047] In some embodiments of this application, one of the two first pickup mating parts 6 includes a mounting protrusion 61 disposed on the volute 52, and the other includes a first mounting groove 62 formed on the volute 52; wherein the mounting protrusion 61 is disposed on the side of the volute 52 facing the cover 12, and the first mounting groove 62 is formed on the periphery of the volute 52; in this embodiment, the automated pickup fixture cooperates with the mounting protrusion 61 and the first mounting groove 62 to pick up the volute 52, thereby enabling the automated pickup fixture to automatically install the volute 52.

[0048] If a part of the automated pick-up tooling is embedded in the first assembly groove 62 and does not protrude from the first assembly groove 62, it ensures that the automated pick-up tooling will not interfere with the automated assembly of the volute 52.

[0049] Since the assembly protrusion 61 is located on the side of the volute 52 facing the cover 12, the automated pick-up tool will not interfere with other structures inside the housing 11 when it limits the assembly protrusion 61 and installs the volute 52 on the cover 12 in the direction from the housing 11.

[0050] To ensure the stability of the automated picking fixture, the first assembly groove 62 and the assembly protrusion 61 are provided at intervals; for example, the assembly protrusion 61 is provided in the upper region of the volute 52, and the first assembly groove 62 is provided in the lower region of the volute 52.

[0051] Please refer to it again. Figures 1 to 2 In some embodiments of this application, the cover 12 is provided with a clearance portion 7, and at least a portion of the mounting protrusion 61 extends from the clearance portion 7 into the mounting cavity 2. The portion of the mounting protrusion 61 extending into the mounting cavity 2 is provided with a first opening 8 communicating with the mounting cavity 2 of the fan 51. This allows the mounting protrusion 61 to not only perform the function of being picked up by an automated picking tool, but also to be reused as an air outlet of the air duct module 100, thereby improving the versatility of the functions of the mounting protrusion 61 and enhancing the functional integration of the air duct module 100.

[0052] The first opening 8 can be either an air inlet or an air outlet, and there is no restriction on this.

[0053] The specific structure of the air duct module 100 is further explained below. The air duct module 100 extends vertically and is plate-shaped, giving it a large size on the plane formed by the vertical and horizontal directions and the front and back directions. The cover 12 is located on the left or right side of the housing 11 to assemble with the housing 11 to form an outer shell. That is, the mounting cavity 2 is open on the left or right side, which makes the opening of the mounting cavity 2 large, which facilitates the assembly of internal components such as the fan assembly 5 by automated assembly equipment.

[0054] In addition, an evaporator is provided inside the air duct module 100. The evaporator is located on the lower side of the fan assembly 5. The shell 11 and the cover 12 are provided with air inlets on the parts opposite to the evaporator, so that the air in the inner liner enters the evaporator from the air inlet and is cooled. The cooled air is guided by the fan assembly 5 to the air outlet duct, and then discharged from the air outlet to the inner liner to realize the refrigeration cycle of the refrigerator.

[0055] In some embodiments of this application, the air outlet 17 is located at the rear end of the air duct module 100, and the first opening 8 is also an air outlet structure, located near the front end of the air duct module 100, so as to improve the uniformity of cooling inside the inner liner and the cooling effect of the refrigerator.

[0056] In some embodiments of this application, the clearance part 7 is an opening structure provided on the cover 12. When the cover 12 is installed on the housing 11, the mounting protrusion 61 on the volute 52 needs to pass through the opening structure on the cover 12; that is, the mounting protrusion 61 can also play the role of positioning the installation position of the cover 12.

[0057] Please see Figures 6 to 7 In some embodiments of this application, the housing 11 includes a housing body 111, the housing body 111 includes a housing bottom 1111 and a housing side portion 1112, the housing bottom 1111 and the housing side portion 1112 surround to form at least a portion of the mounting cavity 2; wherein, the housing bottom 1111 forms the cavity bottom of the mounting cavity 2, and the housing side portion 1112 is arranged in a surrounding manner to form a cavity sidewall portion of the mounting cavity 2.

[0058] In some embodiments of this application, the housing 11 further includes a first heat insulation member 112, which is disposed inside the housing body 111 and installed on the bottom 1111 of the housing. The mounting groove 3 and the plurality of grooves 4 are all formed on the side of the first heat insulation member 112 facing the cover 12. The fan 51 is disposed on the first heat insulation member 112. The first heat insulation member 112 can block the heat exchange between the inside and outside of the housing 1, thereby preventing condensation from occurring on the outer wall of the housing 1.

[0059] In addition, the first insulation component 112 can reduce the cooling capacity loss of the air duct module 100, thereby improving the cooling efficiency of the air duct module 100.

[0060] Based on the technical solution of installing the first insulation component 112 on the bottom of the shell 1111, in order to achieve stable installation of the fan assembly 5 in the mounting cavity 2, the mounting groove 3 and multiple grooves 4 are directly machined on the first insulation component 112, providing precise installation positioning for the fan 51.

[0061] Furthermore, in order to achieve automated assembly of the first insulation component 112, in some embodiments of this application, a clearance notch 9 is formed around the periphery of the first insulation component 112, and the clearance notch 9 is disposed opposite to the cover body 12; wherein, the automated pick-up tool can pick up the first insulation component 112 at the clearance notch 9 to automatically assemble the first insulation component 112 to the bottom of the shell 1111, and the structural feature of the clearance notch 9 being disposed opposite to the shell 11 ensures that when the automated pick-up tool picks up the first insulation component 112 and assembles it to the bottom of the shell 1111, it will not interfere with other structures on the shell body 111.

[0062] It should be noted that there is no limit to the number of clearance gaps 9; there can be one or more, as long as the automated picking fixture can stably pick up the first insulation component 112.

[0063] Of course, the first insulation component 112 may also be provided with other structural features that can be picked up by automated pick-up fixtures to accommodate the clearance gap 9.

[0064] In some embodiments of this application, the shell body 111 is provided with a second opening 10; the clearance notch 9 connects the second opening 10 and the mounting cavity 2; that is, in this embodiment, the clearance notch 9 can be reused as a connecting channel between the second opening 10 and the mounting cavity 2 while realizing the picking function of automated picking tool, thereby improving the functional integration of the air duct module 100.

[0065] The second opening 10 can be either an air inlet or an air outlet.

[0066] In some embodiments of this application, the second opening 10 is an air outlet opening. When the volute 52 is assembled into the mounting cavity 2, the volute 52 is also covered by the second opening 10. That is, the fan mounting cavity is connected to the second opening 10 through the clearance notch 9. After the airflow is introduced into the fan mounting cavity, the airflow can flow out from the first opening 8 and the second opening 10, so that the fan module 100 can outlet air at different positions.

[0067] In some embodiments of this application, the air duct module 100 divides the inner liner into two compartments, left and right, and the first opening 8 and the second opening 10 can respectively input cold air into the two compartments.

[0068] Similarly, the air duct module 100 is provided with air outlets 17 at the positions corresponding to the two compartments, so as to discharge air to the two compartments respectively.

[0069] For example, in the compartment on the left side of the air duct module 100, the air outlet 17 exits air at the rear end of the air duct module 100, and the first opening 8 exits air at the front end of the air duct module 100, so as to improve the uniformity of cooling of the left compartment by the air duct module 100.

[0070] In the compartment on the right side of the air duct module 100, the air outlet 17 also outlets air at the rear end of the air duct module 100, and the second opening 10 outlets air at the front end of the air duct module 100, so as to improve the uniformity of cooling of the right compartment by the air duct module 100.

[0071] Please see Figure 8 In some embodiments of this application, the air duct module 100 further includes a second heat insulation member 13, which is disposed on the outside of the outer shell 1. The second heat insulation member 13 can block the heat exchange between the inside and outside of the outer shell 1, thereby preventing condensation from occurring on the outer wall of the outer shell 1.

[0072] In addition, the second insulation component 13 can reduce the cooling capacity loss of the air duct module 100, thereby improving the cooling efficiency of the air duct module 100.

[0073] In one specific embodiment of this application, the second heat insulation element 13 is disposed on the front side of the outer shell 1.

[0074] In some embodiments of this application, the second insulation member 13 is provided with a second pickup mating part 14 at both oppositely arranged ends. The two second pickup mating parts 14 are close to the side of the second insulation member 13 away from the outer shell 1. Each second pickup mating part 14 includes at least one second assembly groove 141. The automated pickup tooling can pick up the second insulation member 13 at the second assembly groove 141 and assemble the second insulation member 13 from the outer shell 1 to realize the automated assembly of the second insulation member 13.

[0075] Specifically, two second pick-up mating parts 14 are provided at the connection between the left and front sides of the second insulation component 13 and the connection between the right and front sides of the second insulation component 13; the automated pick-up tooling clamps the second insulation component 13 at the two second assembly grooves 141 to assemble the second insulation component 13 onto the housing 11 in the front-back direction, thereby realizing the automated installation of the second insulation component 13.

[0076] In some embodiments of this application, a receiving groove is provided on the front side of the housing 11, which can accommodate the installation of the second insulation component 13; similarly, the receiving groove can also provide a positioning function, so that the automated picking tool can install the second insulation component 13 into a set position.

[0077] Please see Figure 9In some embodiments of this application, the number of second assembly grooves 141 in each second pickup mating part 14 is set to be multiple, and the multiple second assembly grooves 141 are arranged along the length direction of the second heat insulation member 13; the air duct module 100 also includes a protective member 15, the protective member 15 is provided to cover the second heat insulation member 13, and the protective member 15 is provided with a locking protrusion 16 at the position corresponding to the multiple second assembly grooves 141, the locking protrusion 16 is embedded into the corresponding second assembly groove 141; wherein, by reusing the second assembly groove 141 as the installation point between the second heat insulation member 13 and the protective member 15, the assembly and installation of the second heat insulation member 13 and the protective member 15 can be realized, that is, the locking protrusion 16 of the protective member 15 can be embedded into the second assembly groove 141.

[0078] The number of second mounting grooves 141 is the same as the number of locking protrusions 16 on the protective member 15, so that there are multiple points between the second insulation member 13 and the protective member 15, thereby improving the reliability of the mutual fixation between the second insulation member 13 and the protective member 15.

[0079] The protective component 15 covers the portion of the second insulation component 13 exposed to the external environment to improve the aesthetics of the air duct module 100 and provide protection for the second insulation component 13.

[0080] In some embodiments of this application, the first insulation member 112 and the second insulation member 13 are both made of foam.

[0081] This application also proposes a refrigerator, which includes an inner liner and an air duct module 100. The inner liner has a cooling cavity, and the air duct module 100 extends vertically and is disposed in the inner liner to divide the inner liner into a first chamber and a second chamber. The air duct module 100 is as described above. Since this refrigerator adopts all the technical solutions of all the above embodiments, it has at least the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here.

[0082] The first and second chambers are the compartments mentioned above.

[0083] The air duct module 100 provides a more detailed division of the refrigerator's cooling space, namely, into a first chamber and a second chamber in this embodiment, to meet different user needs.

[0084] The inner liner has a cooling chamber, which can be a refrigerator chamber or a freezer chamber. The air duct module 100 is centrally located in the cooling chamber to divide it into a first chamber and a second chamber. The air duct module 100 can supply air to the first chamber and the second chamber separately. Without temperature differentiation, the air duct module 100 can control the airflow in the first chamber and the second chamber to be uniform, thereby ensuring the temperature uniformity of the cooling chamber. With temperature differentiation, the air duct module 100 can control the airflow in the first chamber and the second chamber to be different, so that the inner liner has storage spaces with multiple different temperature ranges, thereby improving the user's convenience.

[0085] The description of orientation in the above embodiments is based on the structure of the air duct module 100 applied to a refrigerator. When the air duct module 100 is applied to refrigeration equipment other than a refrigerator, the orientation of the air duct module 100 can be adjusted adaptively.

[0086] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
