[0005] Specifically, the present disclosure is achieved through the following technical solutions.

[0006] According to a first aspect of an embodiment of the present disclosure, a box assembly is provided, which includes an inner liner and an air duct cover plate. The inner liner is provided with a accommodating cavity, an opening connected to the accommodating cavity, and a first side wall arranged opposite to the opening.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments (or, the implementation manners) of the present application will be clearly and completely described below with reference to the drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0044] If the application embodiments involve directional indications or positional relationships (such as up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a certain posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0045] With the development of social economy and the improvement of people's living standards, refrigeration equipment (such as refrigerators, freezers, etc.) has also become an indispensable household appliance in people's daily life. The refrigerator usually uses an air duct to deliver the cold air generated by the refrigeration system to the refrigeration chamber and the freezing chamber.

[0046] In the related art, the way of installing the air duct in the refrigerator is relatively complex, and the liner of the refrigerator is not conducive to the production and manufacturing of the refrigerator liner in order to adapt to the installation of the air duct.

[0047] As Figure 1 And Figure 2As shown, the refrigerator 10 provided by the present application comprises a cabinet assembly 100 and a cabinet door assembly 200, the cabinet assembly 100 comprises an inner container 110 provided with a containing cavity 111, and the cabinet door assembly 200 is movably arranged on the cabinet assembly 100 to open or close the containing cavity 111.

[0048] As shown, Figure 1 and Figure 2 As shown, in some embodiments, the cabinet door assembly 200 comprises a first cabinet door 210 and a second cabinet door 220, and the cabinet assembly 100 comprises a freezing compartment 140 and a refrigerating compartment 130. The first cabinet door 210 is rotatably connected with the cabinet assembly 100 to open or close the refrigerating compartment 130. The second cabinet door 220 is rotatably connected with the cabinet assembly 100 to open or close the freezing compartment 140.

[0049] As shown, Figures 4 to 11 As shown, in some embodiments, the inner container 110 is further provided with an opening 112 communicating with the containing cavity 111, and the inner container 110 comprises a first side wall 1111 oppositely arranged with the opening 112. The cabinet assembly 100 has a first direction along the depth direction of the containing cavity 111 and a second direction opposite to the first direction. The first side wall 1111 is provided with a first mounting groove 113 along the first direction and a second mounting groove 114 along the second direction, the first mounting groove 113 and the second mounting groove 114 are adjacently arranged, and the side wall of the second mounting groove 114 protrudes the side wall of the first mounting groove 113 to form a first abutting portion 101. The cabinet assembly 100 further comprises an air duct cover plate 120 connected with the inner container 110 to form an air duct 102. The air duct cover plate 120 is provided with a first abutting piece 121, and part of the first abutting piece 121 is located in the first mounting groove 113 and abuttingly matched with the first abutting portion 101 to fixedly connect the inner container 110 with the air duct cover plate 120.

[0050] In this way, when the inner container 110 and the air duct cover plate 120 are installed, part of the first abutting piece 121 arranged on the air duct cover plate 120 is located in the first mounting groove 113 and abuttingly matched with the first abutting portion 101 of the inner container 110, so that the inner container 110 and the air duct cover plate 120 are fixedly connected and the air duct 102 is formed. The first mounting groove 113 arranged along the first direction and the second mounting groove 114 arranged along the second direction are adjacently arranged, and the side wall of the second mounting groove 114 protrudes the side wall of the first mounting groove 113 to form the first abutting portion 101 in the first mounting groove 113. The first abutting portion 101 is formed in this way to abuttingly match with the first abutting piece 121, which is beneficial to demolding of the inner container 110 in the production and manufacturing process, reduces the production and manufacturing difficulty of the inner container 110 of the refrigerator 10, and can improve the production and manufacturing efficiency of the inner container 110.

[0051] It should be noted that, Figure 7The X1 direction shown is the first direction, Figure 7 The X2 direction shown is the second direction.

[0052] In some embodiments, the inner liner 110 is integrally formed by adsorption. Thus, the first mounting groove 113 and the second mounting groove 114 are provided to form the first abutting portion 101, which facilitates the adsorption forming of the inner liner 110 and reduces the difficulty of manufacturing the inner liner 110.

[0053] And, as Figure 8 as well as Figure 11 As shown, there is a certain distance between the bottom wall of the second mounting groove 114 and the first abutting portion 101 , which can reduce the occurrence of adsorption defects such as ribs when the inner liner 110 is adsorbed.

[0054] See you later Figure 2 and Figure 3 As shown, in some embodiments, the refrigerator 10 further includes a compressor 11 , a condenser 12 , an evaporator 13 and an expansion valve 14 , which are respectively arranged in the cabinet assembly 100 to refrigerate the refrigeration compartment 130 and the freezer compartment 140 .

[0055] Combine Figure 3 As shown, when the refrigerator 10 is in operation, the compressor 11 outputs a high-temperature, high-pressure gaseous refrigerant to the condenser 12, which condenses the high-temperature, high-pressure gaseous refrigerant into a medium-temperature, high-pressure refrigerant through the condenser 12. The medium-temperature, high-pressure refrigerant undergoes expansion and throttling by the expansion valve 14, which further reduces the pressure and temperature of the refrigerant, and flows out of the expansion valve 14 as a low-temperature, low-pressure liquid refrigerant to the evaporator 13. The low-temperature, low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 13. The gaseous refrigerant can be transported to the refrigerated compartment 130 and the frozen compartment 140 through the air duct 102, thereby reducing the temperature of the refrigerated compartment 130 and the frozen compartment 140, making it easier to refrigerate or freeze items in the refrigerated compartment 130 and the frozen compartment 140.

[0056] like Figure 2 As shown, in some embodiments, the freezing chamber 140 is disposed below the refrigerating chamber 130 along the height direction of the refrigerator 10 .

[0057] It should be noted that if Figure 2 As shown, the height direction of the refrigerator 10 is the Z-axis direction.

[0058] In some embodiments, the outer wall of the refrigeration compartment 130 is covered with an insulation layer (not shown), and the outer wall of the freezing compartment 140 is covered with an insulation layer (not shown).

[0059] In the prior art, traditional refrigerator air ducts are fixed to the inner container with clips. A boss is provided on the back of the container. The width of the boss varies depending on the width of the wide or narrow duct. This results in the production of the inner container requiring multiple molds, resulting in a waste of resources. Furthermore, the boss takes up space in the refrigerator, reducing the available volume for users and causing a waste of space.

[0060] The solution disclosed in this disclosure can effectively avoid the above problems and is applicable to both wide and narrow air ducts. Figure 3 As shown, the back of the inner tank 110 is also set as a large flat surface, and there is no need to set a boss, which can increase the volume of the refrigerator 10.

[0061] like Figure 7 as well as Figure 8 As shown, in some embodiments, the depth of the first mounting groove 113 along the first direction is greater than the depth of the second mounting groove 114 along the second direction. In this way, by designing the depth of the first mounting groove 113 along the first direction to be greater than the depth of the second mounting groove 114 along the second direction, the first mounting groove 113 and the second mounting groove 114 can be arranged in the inner liner 110 so as to bulge outward as a whole, so that the overall structure occupies less space inside the inner liner 110, which is convenient for the air path arrangement of the air duct 102 structure. In addition, the overall structure bulges toward the inner liner 110. When the inner liner 110 is manufactured (such as adsorption molding or injection molding), the feed obstruction is reduced when the inner liner 110 is foamed, and defects such as insufficient feed, trapped air, and lack of material are less likely to occur.

[0062] It should be noted that if Figure 8 As shown, the depth of the first installation groove 113 along the first direction is h1, and the depth of the second installation groove 114 along the second direction is h2, wherein h1>h2.

[0063] Of course, if Figure 10 as well as Figure 11 As shown, in other embodiments, the depth of the first mounting groove 113 along the first direction is less than the depth of the second mounting groove 114 along the second direction. Thus, by designing the depth of the first mounting groove 113 along the first direction to be less than the depth of the second mounting groove 114 along the second direction, the first mounting groove 113 and the second mounting groove 114 can be arranged in an overall inwardly concave manner in the inner liner 110. This allows the first side wall 1111 of the inner liner 110 to be positioned further back while maintaining the same foam layer thickness, thereby increasing the capacity of the refrigerator 10.

[0064] It should be noted that if Figure 11 As shown, the depth of the first installation groove 113 along the first direction is h3, and the depth of the second installation groove 114 along the second direction is h4, wherein h3<h4.

[0065] likeFigure 8 as well as Figure 11 As shown, in some embodiments, the first mounting groove 113 includes a first inner sidewall 1131 disposed opposite the second mounting groove 114, and the first inner sidewall 1131 is inclined relative to the first sidewall 1111. Thus, by slanting the first inner sidewall 1131 disposed opposite the second mounting groove 114 in the first mounting groove 113 relative to the first sidewall 1111, it is possible to facilitate demolding of the inner liner 110 during the manufacturing process, reduce the difficulty of manufacturing the inner liner 110, and thereby improve the manufacturing efficiency of the refrigerator 10.

[0066] Of course, if Figure 8 as well as Figure 11 As shown, in other embodiments, the second mounting groove 114 includes a second inner sidewall 1141 disposed opposite the first mounting groove 113, and the second inner sidewall 1141 is inclined relative to the first sidewall 1111. Thus, by slanting the second inner sidewall of the second mounting groove 114, which is disposed opposite the first mounting groove 113, relative to the first sidewall 1111, it is possible to facilitate demolding of the inner liner 110 during the manufacturing process, reduce the difficulty of manufacturing the inner liner 110, and thereby improve the manufacturing efficiency of the refrigerator 10.

[0067] It should be noted that, in the present disclosure, only the first inner wall 1131 may be inclined relative to the first side wall 1111 or only the second inner wall 1141 may be inclined relative to the first side wall 1111; or both the first inner wall 1131 and the second inner wall 1141 may be inclined relative to the first side wall 1111 at the same time.

[0068] like Figure 8 as well as Figure 11 As shown, in some embodiments, the first abutment 121 includes a first connection portion 1211 and a first clamping portion 1212. The first connection portion 1211 is connected to the air duct cover plate 120. The first clamping portion 1212 is disposed on the first connection portion 1211. The first clamping portion 1212 is clamped and fixed to the first abutment portion 101. In this way, the first clamping portion 1212 is connected to the air duct cover plate 120 via the first connection portion 1211. The air duct cover plate 120 is clamped and fixed to the first abutment portion 101 of the inner liner 110 using the first clamping portion 1212, so that the air duct cover plate 120 and the first side wall 1111 of the inner liner 110 form the air duct 102. This method facilitates the connection between the air duct cover plate 120 and the first side wall 1111 of the inner liner 110, and the method for forming the air duct 102 is simple.

[0069] like Figure 8 as well as Figure 11 As shown, in some embodiments, the first engaging portion 1212 includes a hook, which is located in the first mounting groove 113 and is engaged and fixed with the first abutting portion 101 .

[0070] likeFigure 5 and Figure 6 As shown in FIG. 1, in some embodiments, the first abutting part 101 comprises a plurality of first abutting parts 101, and the plurality of first abutting parts 101 are arranged along the width direction and / or the height direction of the inner container 110. The air duct cover plate 120 is provided with a plurality of first abutting members 121 one-to-one corresponding to the plurality of first abutting parts 101, so that the plurality of first abutting members 121 abut and cooperate with the plurality of first abutting parts 101 one-to-one corresponding. In this way, the first side wall 1111 of the inner container 110 is provided with a plurality of first abutting parts 101, and the air duct cover plate 120 is provided with a plurality of first abutting members 121 one-to-one corresponding to the plurality of first abutting parts 101. The inner container 110 and the air duct cover plate 120 are connected by the plurality of first abutting parts 101 and the plurality of first abutting members 121 one-to-one corresponding to each other to realize the connection between the inner container 110 and the air duct cover plate 120, so as to form the air duct 102. This mode can improve the reliability of the connection between the inner container 110 and the air duct cover plate 120.

[0071] It should be noted that the specific implementation mode of the arrangement of the first abutting member 121 can be various, including that the plurality of first abutting members 121 are arranged along the width direction of the inner container 110, the plurality of first abutting members 121 are arranged along the height direction of the inner container 110, and the plurality of first abutting members 121 are arranged along the width direction and the height direction of the inner container 110.

[0072] It should be noted that, Figure 6 The Y direction shown in FIG. 1 is the width direction of the inner container 110, Figure 6 The Z direction shown in FIG. 1 is the height direction of the inner container 110.

[0073] As shown in FIG. 1, Figure 4 , Figure 5 , Figure 12 and Figure 13 In some embodiments, the accommodating cavity 111 further comprises a top wall 1112 connected with the first side wall 1111. The connection part of the first side wall 1111 and the top wall 1112 is provided with a third mounting groove 116. The third mounting groove 116 comprises a third inner side wall 1161. Part of the third inner side wall 1161 is protrudingly arranged to form a second abutting part 103 in the third mounting groove 116. The air duct cover plate 120 is further provided with a second abutting member 122. Part of the second abutting member 122 is located in the third mounting groove 116 and abuts and cooperates with the second abutting part 103. In this way, the connection part of the first side wall 1111 and the top wall 1112 is further provided with the third mounting groove 116. Part of the third inner side wall 1161 of the third mounting groove 116 is protrudingly arranged to form the second abutting part 103 in the third mounting groove 116. The second abutting member 122 of the air duct cover plate 120 abuts and cooperates with the second abutting part 103, further improving the reliability of the connection between the inner container 110 and the air duct cover plate 120.

[0074] As shown in FIG. 1, Figure 13As shown, in some embodiments, the third mounting groove 116 further includes a fourth inner sidewall 1162 disposed opposite the third inner sidewall 1161, and the fourth inner sidewall 1162 is disposed at an angle relative to the first sidewall 1111. Thus, the fourth inner sidewall 1162 disposed opposite the third inner sidewall 1161 in the third mounting groove 116 is disposed at an angle relative to the first sidewall 1111, which facilitates demolding of the inner liner 110 during the manufacturing process, reduces the difficulty of manufacturing the inner liner 110, and thereby improves the manufacturing efficiency of the refrigerator 10.

[0075] like Figure 13 As shown, in some embodiments, the second abutment 122 includes a second connection portion 1221 and a second clamping portion 1222. The second connection portion 1221 is connected to the air duct cover plate 120, and the second clamping portion 1222 is disposed on the second connection portion 1221. The second clamping portion 1222 is clamped and fixed to the second abutment portion 103. In this way, the second clamping portion 1222 is connected to the air duct cover plate 120 via the second connection portion 1221, and the air duct cover plate 120 is clamped and fixed to the second abutment portion 103 of the inner liner 110 using the second clamping portion 1222, so that the air duct cover plate 120 and the first side wall 1111 of the inner liner 110 form the air duct 102. This method facilitates the connection between the air duct cover plate 120 and the first side wall 1111 of the inner liner 110, and the method for forming the air duct 102 is simple.

[0076] like Figure 13 As shown, in some embodiments, the second engaging portion 1222 includes a hook, which is located in the third mounting groove 116 and is engaged and fixed with the first abutting portion 101 .

[0077] like Figures 14 to 16 As shown, in some embodiments, the inner liner 110 is provided with a plurality of first ribs 115. The first ribs 115 are arranged along the bottom wall from the first abutting portion 101 to the second mounting groove 114, and the plurality of first ribs 115 are arranged at intervals. In this way, by providing the plurality of first ribs 115 on the inner liner 110 and the first ribs 115 being arranged along the bottom wall from the first abutting portion 101 to the second mounting groove 114, the strength of the first abutting portion 101 is improved, thereby ensuring the reliability of the clamping and fixing of the first abutting portion 101 to the first clamping portion 1212.

[0078] like Figures 14 to 16 As shown, in some embodiments, the inner liner 110 is further provided with a plurality of second ribs 117. The second ribs 117 are arranged along the second abutting portion 103 to the side wall of the inner liner 110, and the plurality of second ribs 117 are arranged at intervals. In this way, by providing the plurality of second ribs 117 on the inner liner 110, and by the second ribs 117 being arranged along the second abutting portion 103 to the side wall of the inner liner 110, the strength of the second abutting portion 103 is improved, thereby ensuring the reliability of the clamping and fixing of the second abutting portion 103 to the second clamping portion 1222.

[0079] It is understandable that the number of the first ribs 115 and the second ribs 117 can be two, three, four or five, etc., and can be set according to actual needs, which will not be described in detail here.
