DETAILED DESCRIPTION

[0043] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0044] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, 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 specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not 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 and freezers) have become indispensable household appliances in people's daily lives. Refrigerators usually use air ducts to transport the cold air generated by the refrigeration system to the refrigerator and freezer compartments.

[0046] In the related art, the method of installing the air duct in the refrigerator is relatively complicated, and the inner tank of the refrigerator is not conducive to the production of the inner tank of the refrigerator in order to adapt to the installation of the air duct.

[0047] like Figure 1 as well as Figure 2 As shown, the present application provides a refrigerator 10, including a body assembly 100 and a door assembly 200, the body assembly 100 includes an inner liner 110, the inner liner 110 is provided with a accommodating cavity 111, and the door assembly 200 is movably arranged on the body assembly 100 to open or close the accommodating cavity 111.

[0048] like Figure 1 as well as Figure 2 As shown, in some embodiments, the door assembly 200 includes a first door 210 and a second door 220, and the cabinet assembly 100 includes a freezer compartment 140 and a refrigerator compartment 130. The first door 210 is rotatably connected to the cabinet assembly 100 to open or close the refrigerator compartment 130. The second door 220 is rotatably connected to the cabinet assembly 100 to open or close the freezer compartment 140.

[0049] like Figures 4 to 11As shown, in some embodiments, the inner liner 110 is further provided with an opening 112 communicating with the accommodating cavity 111. The inner liner 110 includes a first sidewall 1111 disposed opposite the opening 112. The box assembly 100 has a first direction along the depth direction of the accommodating cavity 111 and a second direction opposite to the first direction. The first sidewall 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 disposed adjacent to each other, and the sidewall of the second mounting groove 114 protrudes from the sidewall of the first mounting groove 113 to form a first abutting portion 101. The box assembly 100 also includes an air duct cover 120, which is connected to the inner liner 110 to form an air duct 102. The air duct cover 120 is provided with a first abutting member 121 . Part of the first abutting member 121 is located in the first mounting groove 113 and abuts against the first abutting portion 101 to securely connect the liner 110 to the air duct cover 120 .

[0050] Thus, when the inner liner 110 is installed with the air duct cover 120, the first abutment member 121 provided on the air duct cover 120 is partially located in the first mounting groove 113 and abuts and cooperates with the first abutment portion 101 of the inner liner 110, thereby fixing the inner liner 110 and the air duct cover 120 together and forming the air duct 102. The first mounting groove 113 provided along the first direction and the second mounting groove 114 provided along the second direction are adjacently provided, and the sidewall of the second mounting groove 114 protrudes from the sidewall of the first mounting groove 113, forming the first abutment portion 101 within the first mounting groove 113. Forming the first abutment portion 101 in this manner to abut and cooperate with the first abutment member 121 facilitates demolding of the inner liner 110 during the manufacturing process, reduces the difficulty of manufacturing the inner liner 110 of the refrigerator 10, and can improve the manufacturing efficiency of the inner liner 110.

[0051] It should be noted that Figure 7 The 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 3As 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 8As 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] like Figure 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 11As 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] like Figure 5 as well as Figure 6As shown, in some embodiments, the first abutment portion 101 includes a plurality of first abutment portions 101, and the plurality of first abutment portions 101 are spaced apart along the width direction and / or height direction of the inner liner 110. The air duct cover plate 120 is provided with a plurality of first abutment members 121 in a one-to-one correspondence, so that the plurality of first abutment members 121 abut and cooperate with the plurality of first abutment portions 101 in a one-to-one correspondence. In this way, the first side wall 1111 of the inner liner 110 is provided with a plurality of first abutment portions 101, and the air duct cover plate 120 is provided with a one-to-one correspondence with the plurality of first abutment members 121. The inner liner 110 and the air duct cover plate 120 are connected to the air duct cover plate 120 by the one-to-one correspondence between the plurality of first abutment portions 101 and the plurality of first abutment members 121 to form the air duct 102. This method can improve the reliability of the connection between the inner liner 110 and the air duct cover plate 120.

[0071] It should be noted that there can be many specific implementation methods for the setting of the first abutment 121, including multiple first abutment 121 being set at intervals along the width direction of the inner liner 110, multiple first abutment 121 being set at intervals along the height direction of the inner liner 110, and multiple first abutment 121 being set at intervals along both the width direction and the height direction of the inner liner 110.

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

[0073] like Figure 4 、 Figure 5 、 Figure 12 as well as Figure 13 As shown, in some embodiments, the accommodating chamber 111 further includes a top wall 1112 connected to the first side wall 1111. A third mounting groove 116 is provided at the connection between the first side wall 1111 and the top wall 1112. The third mounting groove 116 includes a third inner side wall 1161. A portion of the third inner side wall 1161 protrudes to form a second abutting portion 103 within the third mounting groove 116. The air duct cover 120 further includes a second abutting member 122. A portion of the second abutting member 122 is located within the third mounting groove 116 and abuts against the second abutting portion 103. Thus, the third mounting groove 116 is further provided at the connection between the first side wall 1111 and the top wall 1112, and a portion of the third inner side wall 1161 of the third mounting groove 116 protrudes to form the second abutting portion 103 within the third mounting groove 116. The second abutting member 122 of the air duct cover 120 abuts and cooperates with the second abutting portion 103 , further improving the reliability of the connection between the inner liner 110 and the air duct cover 120 .

[0074] like 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.

[0080] like Figure 14 As shown, in some embodiments, the third mounting groove 116 includes a plurality of third mounting grooves 116, and the plurality of third mounting grooves 116 are spaced apart along the width direction of the inner liner 110.
