[0002] To increase the drawer depth of the refrigerator's cooling compartment, some air ducts are located at the top of the cooling compartment. The structural components of the top air duct are mounted to the refrigerator's inner liner via side panels. However, due to the long span of the air duct, the side panels are also quite long. Furthermore, manufacturing tolerances exist for various structural components of both the refrigerator's inner liner and the air duct assembly, resulting in the side panels not being well-compatible with other structural components of the inner liner and the air duct assembly.

[0060] like Figure 1 As shown, the side plate 11 for installing the air duct assembly provided in this embodiment of the present invention includes a first plate 111 and a second plate 112. The first plate 111 and the second plate 112 are distributed along the length direction of the side plate. Both the first plate 111 and the second plate 112 are provided with mounting positions 110 and are adapted to be fixedly connected to the refrigerator inner liner through the mounting positions 110. The first plate 111 and the second plate 112 are interlocked with each other along the length direction of the side plate 11; or, the first plate 111 is adapted to define a slot with the refrigerator inner liner, and the second plate 112 is inserted into the slot along the length direction of the side plate 11.

[0061] The side panel 11 is installed on one side of the refrigerator's inner liner. Two side panels 11 are located on opposite sides of the inner liner, forming the mounting base for the components in the air duct assembly. The side panel 11 can serve as the mounting base for any type of air duct structure. For example, the side panel 11 can be installed on the top of the cooling compartment 41 as the mounting base for the top air duct assembly. The side panel 11 can also be installed at the rear of the cooling compartment 41 as the mounting base for the rear air duct assembly. The side panel 11 is a strip-shaped plate, which can be a regular rectangle or an irregular shape. The specific shape can be adapted to the air duct structure and other assembly structures.

[0062] This embodiment takes the side panel 11 installed on the top of the refrigeration compartment 41 as an example. See [reference needed]. Figure 2 The refrigerator body 4 has a refrigeration compartment 41, and side panels 11 are fixed to opposite sides of the refrigeration compartment 41 in the width direction. The length direction of the side panels 11 is consistent with the depth direction of the refrigeration compartment 41, that is, the first panel 111 and the second panel 112 are distributed along the depth direction of the refrigeration compartment 41 and are interlocked with each other in the depth direction of the refrigeration compartment 41. In this case, the interlocking end of the second panel 112 is supported on the first panel 111. The depth direction of the refrigeration compartment 41 is consistent with the opening direction of the refrigeration compartment 41, and the rear wall surface of the refrigeration compartment 41 is opposite to the opening.

[0063] Mounting holes or honeycomb blocks are provided at mounting positions 110 on the first plate 111 and the second plate 112. Both the first plate 111 and the second plate 112 are fixedly connected to the refrigerator liner by fasteners such as screws passing through the mounting holes or honeycomb blocks. When installing the refrigerator air duct assembly, the first plate 111 is first fixedly connected to the refrigerator liner by fasteners passing through the mounting positions 110. Then, one end of the second plate 112 is inserted into the first plate 111. Then, the second plate 112 is fixedly connected to the refrigerator liner by fasteners passing through the mounting positions 110. Finally, the other structural components of the air duct assembly are assembled with the side plate 11.

[0064] The side plate 11 for installing the air duct assembly provided in this embodiment of the utility model is achieved by first plate 111 and second plate 112 being interlocked with each other along the length of the side plate 11, or by second plate 112 being inserted into a slot defined by first plate 111 and the refrigerator inner liner. This allows for assembly and adjustment of first plate 111 and second plate 112 along the length of the side plate 11, ensuring that the side plate 11 is compatible with the manufacturing tolerances of the refrigerator inner liner and other structural components of the air duct assembly. The end of second plate 112 closest to first plate 111 does not require a mounting position 110, simplifying the assembly process.

[0065] See Figure 1In some embodiments of this utility model, the length of the first plate 111 is less than the length of the second plate 112. The first plate 111 is provided with a plurality of mounting positions 110, and the second plate 112 is provided with a mounting position 110. The mounting position 110 on the second plate 112 is close to the end of the second plate 112 that is away from the first plate 111.

[0066] In this embodiment, multiple mounting positions 110 are provided on the first plate 111 to ensure its load-bearing capacity. A shorter length for the first plate 111 reduces manufacturing tolerances and ensures that all mounting positions 110 can be properly assembled with the refrigerator liner. The second plate 112 is longer and has only one mounting position 110, ensuring that its mounting position 110 can be properly aligned with the refrigerator liner by adjusting the second plate 112.

[0067] Specifically, see Figure 1 The first plate 111 has two mounting positions 110, which are spaced apart along its length. In practical applications, the number of mounting positions 110 can be adjusted according to the length span of the first plate 111 or the required load-bearing capacity. The mounting positions 110 on the second plate 112 are located at the end furthest from the first plate 111. One end of the second plate 112 is supported by the first plate 111, and the other end is fixed to the refrigerator liner by a fastener.

[0068] In some embodiments of this utility model, a slot may be provided at one end of the first plate 111, and a plugging protrusion 1121 may be provided at one end of the second plate 112. The plugging protrusion 1121 of the second plate 112 is inserted into the slot on the first plate 111, that is, the first plate 111 and the second plate 112 can be plugged into each other without the help of the refrigerator liner.

[0069] See Figure 1 In some other embodiments of the present invention, the first plate 111 is provided with a plug-in portion 1111 at one end near the second plate 112. The plug-in portion 1111 is adapted to define a slot between itself and the inner liner of the refrigerator. The second plate 112 is provided with a plug-in protrusion 1121 at one end, which is inserted into the slot.

[0070] It is understandable that after the first plate 111 is fixed to the refrigerator liner, there is a certain gap between the insertion part 1111 on it and the refrigerator liner, thus forming a slot, and the insertion part 1111 forms the groove wall of the slot. The insertion protrusion 1121 of the second plate 112 is inserted into the slot through this gap. In this embodiment, the insertion structure on the first plate 111 is simplified by forming a slot between the refrigerator liner and the first plate 111.

[0071] Furthermore, the first plate 111 has multiple insertion portions 1111 along the width direction of the side plate 11, and the second plate 112 has multiple insertion protrusions 1121 along the width direction of the side plate 11. The multiple insertion portions 1111 and the multiple insertion protrusions 1121 are arranged in a one-to-one correspondence. Specifically, the first plate 111 has two insertion portions 1111 and the second plate 112 has two insertion protrusions 1121, which ensures high connection reliability between the first plate 111 and the second plate 112, and also facilitates quick assembly of the first plate 111 and the second plate 112. Of course, more insertion portions 1111 and insertion protrusions 1121 can be provided according to actual needs.

[0072] Optionally, a connector 1111 of the first plate 111 protrudes from the edge of the first plate 111 along the width direction of the side plate 11. See also Figure 1 The uppermost insertion part 1111 of the side panel 11 in the width direction protrudes from the upper edge of the first plate 111, so that the slot defined between the insertion part 1111 and the refrigerator inner liner has an upward opening. In this way, when installing the second plate 112, one end of the second plate 112 can be quickly inserted and positioned through the insertion part 1111.

[0073] Such as 3 and Figure 4 As shown, this embodiment of the present invention also provides a refrigerator air duct assembly, including a side plate 11 and an air duct cover 15 as described in any of the above embodiments. The two side plates 11 are respectively adapted to be installed on opposite sides of the refrigeration compartment 41. The first plate 111 is located near the rear wall of the refrigeration compartment 41 relative to the second plate 112. Both ends of the air duct cover 15 are fixedly connected to the first plate 111 and the second plate 112 respectively, and a top air duct 101 is defined between the air duct cover 15 and the upper wall of the refrigeration compartment 41.

[0074] Two side plates 11 are respectively located on the top sides of the refrigeration chamber 41. The first plate 111 is close to the rear wall of the refrigeration chamber 41 relative to the second plate 112. That is, the first plate 111 and the second plate 112 are distributed along the depth direction of the refrigeration chamber 41 and are interlocked with each other in the depth direction of the refrigeration chamber 41.

[0075] When installing the refrigerator air duct assembly, the first plate 111 and the second plate 112 are installed in sequence, then the components inside the top air duct 101 are installed, and finally the air duct cover 15 and the side plate 11 are assembled to complete the assembly of the air duct assembly.

[0076] The two ends of the duct cover 15 in the depth direction of the refrigeration chamber 41 are fixedly connected to the first plate 111 and the second plate 112, respectively. During the assembly of the side plate 11 and the duct cover 15, the manufacturing tolerances of the duct cover 15 can be accommodated by adjusting the assembly of the first plate 111 and the second plate 112 in the length direction, thus ensuring the normal assembly of the side plate 11 and the duct cover 15.

[0077] like Figure 3 and Figure 7 As shown, the refrigerator air duct assembly provided in this embodiment of the present invention also includes a condensate collection component 17. An evaporator 2 is adapted to be installed within the top air duct 101. The condensate collection component 17 is located between the evaporator 2 and the air duct cover plate 15. The two sides of the condensate collection component 17 are respectively slidably engaged with the first plates 111 of the two side plates 11 in the depth direction of the refrigeration compartment 41, and are supported on the first plates 111. It can be understood that the two ends of the condensate collection component 17 in the width direction of the refrigeration compartment 41 are respectively slidably engaged with the two first plates 111, and are supported on the two first plates 111 through a sliding engagement structure.

[0078] When installing the refrigerator air duct assembly, after the first plate 111 and the second plate 112 are installed, the condensate collection piece 17 is slidably pushed between the two first plates 111, and the two first plates 111 support the condensate collection piece 17. Then the air duct cover 15 is assembled with the side plate 11.

[0079] In this embodiment, the condensate collection component 17 is removably slidably fitted to the first plate 111, enabling rapid installation of the condensate collection component 17 and improving the stability and reliability of the connection between the condensate collection component 17 and the side plate 11. Since the condensate collection component 17 is supported by the first plate 111, the pressure of the condensate collection component 17 on the duct cover 15 is reduced, improving the reliability of the connection to the duct cover 15. Furthermore, the first plate 111 has multiple mounting positions 110 with high load-bearing capacity; supporting the condensate collection component 17 on the first plate 111 reduces the load on the second plate 112, also contributing to improved structural reliability.

[0080] In this embodiment of the invention, the condensate collector 17 and the first plate 111 can be slidably fitted together via a groove or guide rail. Figure 8 As shown, the condensate collector 17 has positioning bosses 171 on both sides. The two first plates 111 have sliding grooves 1112 on their opposite sides. The positioning bosses 171 are slidably disposed within the corresponding sliding grooves 1112. Alternatively, sliding grooves can be provided on both sides of the condensate collector 17, while positioning bosses can be provided on the opposite sides of the two first plates 111.

[0081] Further, see Figure 1The chute 1112 includes a positioning groove 1112a and a guide groove 1112b. The positioning groove 1112a extends along the depth direction of the refrigeration chamber 41. The width of the guide groove 1112b gradually increases from the positioning groove 1112a away from it. The groove wall of the guide groove 1112b away from the upper wall of the refrigeration chamber 41 is inclined downward.

[0082] The groove wall of the guide groove 1112b that is away from the upper wall of the refrigeration chamber 41 is the lower groove wall of the guide groove 1112b, and this groove wall forms a guide surface. When installing the condensate collection component 17, the positioning boss 171 of the condensate collection component 17 is pushed into the flared end of the guide groove 1112b, and then the condensate collection component 17 is pushed upwards along the guide surface of the guide groove 1112b. (See [reference]). Figure 9 After the positioning boss 171 enters the positioning groove 1112a, it pushes the condensate collector 17 to rotate upward around the positioning boss 171 by a certain angle. Then it continues to advance forward along the positioning groove 1112a until the positioning boss 171 abuts against the end of the positioning groove 1112a away from the guide groove 1112b, indicating that the condensate collector 17 is installed in place. See [link to documentation]. Figure 7 .

[0083] In this embodiment, by setting a guide groove 1112b, and the width of the guide groove 1112b gradually increases from the positioning groove 1112a away from the positioning groove 1112a, the positioning boss 171 of the condensate collection component 17 can be easily and quickly pushed into the positioning groove 1112a, thus realizing the quick installation of the condensate collection component 17.

[0084] Furthermore, a hook 1116 is provided in the positioning groove 1112a, which confines the positioning boss 171 within the positioning groove 1112a. This prevents the condensate collector 17 from falling out of the positioning groove 1112a.

[0085] Based on the above embodiment, each first plate 111 has two sliding grooves 1112, one of which is closer to the rear wall of the refrigeration chamber 41 and farther from the upper wall of the refrigeration chamber 41 than the other. That is, the two sliding grooves 1112 are staggered in the height and depth directions of the refrigeration chamber 41. At least one sliding groove 1112 has a positioning groove 1112a with a hook 1116.

[0086] In this embodiment, by staggering the arrangement of two sliding grooves 1112, the support length of the first plate 111 on the condensate collection component 17 in the depth direction of the refrigeration chamber 41 is extended. This can reduce the relative sliding length between the condensate collection component 17 and a single sliding groove, and can also effectively limit the rotation of the condensate collection component 17 relative to the first plate 111, reduce stress concentration, and improve the structural stability of the condensate collection component 17.

[0087] See Figure 4 and Figure 5 In this embodiment of the present invention, the first plate 111 is provided with a slot 1113 at one end away from the second plate 112, and the air duct cover 15 is provided with a first mounting part 151 corresponding to the slot 1113. The first mounting part 151 is inserted into the slot 1113 along the depth direction of the refrigeration chamber 41.

[0088] Specifically, the air duct cover 15 has two first mounting parts 151 at one end near the rear wall of the cooling chamber 41. The two first mounting parts 151 are inserted one-to-one into the slots 1113 of the two first plates 111. The slots 1113 are located at the bottom of the first plates 111, and the air duct cover 15 is installed at the bottom of the first plates 111. The first mounting parts 151 protrude from the air duct cover 15 along the depth direction of the cooling chamber 41. This avoids gaps between the air duct cover 15 and the side plate 11, improving the appearance.

[0089] When installing the duct cover 15, first insert the first mounting part 151 of the duct cover 15 into the slot 1113, and then install and fix the end of the duct cover 15 away from the rear wall of the refrigeration chamber 41. During the installation process, the slot 1113 plays an auxiliary positioning role for the duct cover 15, making the installation convenient.

[0090] See Figure 10 and Figure 11 In this embodiment of the present invention, a portion of the first mounting part 151 is located inside the slot 1113, and another portion is located outside the slot 1113. The portion located outside the slot 1113 is provided with a mounting hole, and the air duct cover 15 is fixedly connected to the side plate 11 by a first fastener passing through the mounting hole.

[0091] Specifically, see Figure 6 The slot 1113 has a first groove portion facing away from the rear wall and a second groove portion facing the refrigerator liner on the same side as the first plate 111. The first groove portion and the second groove portion are connected to form the groove of the slot 1113, and there is a gap between the second groove portion and the side wall of the refrigerator liner. The first mounting portion 151 is inserted into the slot 1113 from the first groove portion, with a portion located inside the slot 1113 and another portion located outside the slot 1113. The mounting hole on the first mounting portion 151 is opposite to the gap. This gap provides clearance space for the installation of the first fastener.

[0092] When installing the duct cover 15, insert the first mounting part 151 of the duct cover 15 into the slot 1113, and then install and fix the end of the duct cover 15 away from the rear wall of the refrigeration chamber 41. Then, insert the first fastener, such as a screw, into the mounting hole and the first plate 111 through the gap to secure the first mounting part 151 and the first plate 111.

[0093] See Figure 10 and Figure 12 In this embodiment of the present invention, the second plate 112 is provided with a connecting block 1122. The rear wall of the duct cover 15, away from the refrigeration chamber 41, is provided with a second mounting portion 152 corresponding to the connecting block 1122. The second mounting portion 152 is connected to the connecting block 1122 via a second fastener.

[0094] Specifically, the duct cover 15 has two second mounting portions 152 at one end away from the rear wall of the refrigeration chamber 41. Each of the two second mounting portions 152 corresponds to a connecting block 1122 of one of the two second plates 112. The connecting block 1122 is a boss protruding along the width direction of the refrigeration chamber 41, and the second mounting portions 152 protrude from the duct cover 15 along the depth direction of the refrigeration chamber 41. The second mounting portions 152 are located at the bottom of the connecting blocks 1122 and are fastened using a second fastener, such as a screw.

[0095] When the first plate 111 has a slot 1113, when installing the duct cover 15, the first mounting part 151 of the duct cover 15 is inserted into the slot 1113, and then the end of the duct cover 15 away from the rear wall of the refrigeration chamber 41 is fixed to the second plate 112 by the second fastener. The first mounting part 151 and the second plate 112 can be further fastened together by the first fixing part to ensure reliable installation of the duct cover 15 and the side plate 11.

[0096] like Figure 3 and Figure 4 As shown, the refrigerator air duct assembly provided in this embodiment of the present invention further includes a first support member 12, a second support member 13, and a heat insulation member 14. The two ends of the first support member 12 are respectively supported on two first plates 111. The second plates 112 are provided with slots 1114, and the two ends of the second support member 13 are respectively engaged in and supported within the slots 1114 of the two second plates 112. The heat insulation member 14 is located between the condensate collection member 17 and the air duct cover plate 15, and the two ends of the heat insulation member 14 are respectively supported on the first support member 12 and the second support member 13.

[0097] The first support member 12 is disposed near the rear wall of the refrigeration chamber 41, and the second support member 13 is disposed near the opening of the refrigeration chamber 41. The first plate 111 has a first supporting portion for supporting the first support member 12, and the second plate 112 has a second supporting portion, i.e., a slot 1114, for supporting the second support member 13. The heat insulation member 14 is supported at both ends of the heat insulation member 14 along the depth direction of the refrigeration chamber 41 by the first support member 12 and the second support member 13. The first support member 12 and the second support member 13 are encapsulated between the heat insulation member 14 and the air duct cover 15.

[0098] The installation steps for the heat insulation component 14 are as follows: Side plates 11 are fixedly installed on the two opposite inner wall surfaces of the refrigeration chamber 41; the two ends of the first support member 12 are placed on the first bearing portions of the two first plates 111; one end of the heat insulation component 14 is placed on the first support member 12, and the other end of the heat insulation component 14 is supported by one hand to a position higher than the slot 1114; the other hand is used to engage the two ends of the second support member 13 within the slots 1114 of the two second plates 112, thus allowing the other end of the heat insulation component 14 to rest on the second support member 13. After the heat insulation component 14 is installed, the two ends of the duct cover 15 are connected to the first plate 111 and the second plate 112 respectively.

[0099] Specifically, the opening of the slot 1114 faces away from the rear wall, which makes it easy for installers to observe the position of the slot 1114 so that both ends of the second support member 13 can be pushed into the slot 1114. One side wall of the slot 1114 forms the second bearing part of the second plate member 112.

[0100] Furthermore, each of the two first plates 111 has a boss on its opposite side, which forms the first bearing portion of the first plate 111, and the two ends of the first support member 12 are respectively supported on the two bosses. Optionally, the first plate 111 has a limiting groove corresponding to the position of the boss, and the two ends of the first support member 12 have corresponding limiting protrusions. When the heat insulation member 14 is installed, the first support member 12 can be prevented from falling off the boss by the cooperation of the limiting protrusions and the limiting groove.

[0101] In some embodiments of this utility model, at least one of the first support member 12 and the second support member 13 is a light strip. Thus, the first support member 12 and / or the second support member 13 can be used for both lighting and supporting the heat insulation member 14, achieving functional reuse of the light strip and saving space in the cooling room 41. The light strip can be a general-purpose light or an ambient light.

[0102] Optionally, the refrigerator air duct assembly provided in this embodiment of the present invention further includes a sterilization module 16, see [link to relevant documentation]. Figure 2 and Figure 4The insulation component 14 is made of insulating foam, and its two sides are respectively attached to the condensate collection component 17 and the duct cover 15. A clearance groove 141 is provided on the side of the insulating foam facing the duct cover, and the sterilization module 16 is housed within the receiving space defined by the clearance groove 141 and the duct cover 15. In this embodiment, the sterilization module 16 is housed within the thickness of the insulating foam, which reduces the space occupied by the refrigeration chamber 41.

[0103] See Figure 3 and Figure 4 The refrigerator air duct assembly provided in this embodiment of the present invention also includes a return air inlet structure 18. See also... Figure 12 The second plate 112 has a locking block 1123 at the end furthest from the first plate 111. The return air vent structure 18 has clips 181 at both ends, which engage with the locking blocks 1123 of the two second plates 112 one-to-one. After installing the condensate collection component 17, the return air vent structure 18 is quickly and easily installed by engaging it with the two second plates 112.

[0104] Specifically, the return air vent structure 18 has an outer shell that covers the bottom of the second plate 112 away from the first plate 111 and covers the end of the duct cover 15 away from the rear wall of the cooling chamber 41.

[0105] like Figure 7 and Figure 13 As shown in the embodiment of this utility model, the top of the end of the first plate 111 away from the second plate 112 is provided with a notch 1115. The notch 1115 and the rear wall of the refrigeration chamber 41 define a positioning groove, which is suitable for supporting and positioning the fan assembly 5.

[0106] Specifically, the top of the end of the first plate 111 away from the second plate 112 is provided with an "L"-shaped notch 1115. When the first plate 111 is installed in the inner liner of the refrigerator, the "L"-shaped notch 1115 and the rear wall of the refrigeration compartment 41 define a "U"-shaped positioning groove. The opening of the "U"-shaped positioning groove faces upward. When the fan assembly 5 is installed, the two ends of the fan assembly 5 are placed in the two positioning grooves respectively, thereby limiting the position of the fan assembly 5. The fan assembly 5 is supported by the bottom of the positioning groove.

[0107] In this embodiment of the present invention, at least one of the two side plates 11 has a second plate 112 provided with a clearance opening 1124, which is suitable for pipelines to pass through.

[0108] like Figure 2As shown, this embodiment of the present invention also provides a refrigerator, which includes a cabinet 4, a rear air duct assembly 3, and a top air duct assembly 1. The top air duct assembly 1 is the refrigerator air duct assembly of any of the above embodiments. The cabinet 4 is provided with a cooling compartment 41, the top air duct assembly 1 is installed on the top of the cooling compartment 41, and the rear air duct assembly 3 is installed on the rear wall of the cooling compartment 41 and connected to the top air duct assembly 1. The heat insulation member 14 defines the outlet of the top air duct 101 between itself and the rear wall of the cooling compartment 41, and the outlet of the top air duct 101 is adapted to connect with the inlet of the rear air duct assembly.

[0109] Furthermore, the refrigerator also includes an evaporator 2 and a fan assembly 5, which are disposed within the top air duct. The air intake of the fan assembly 5 faces the evaporator 2 within the top air duct 101, and the air outlet of the fan assembly 5 faces the back air duct of the back air duct assembly 3. Under the action of the fan assembly 5, air in the cooling compartment 41 enters the top air duct 101 through the return air inlet structure 18, flows along the top air duct 101 past the evaporator 2, enters the back air duct assembly from the outlet of the top air duct 101, and then enters the cooling compartment 41 from the air outlet on the back air duct assembly.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention.
