[0088] The embodiments of the present application will be described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary. The following embodiments are described below with reference to Figures 1-16 The refrigerator 100 according to the first aspect of the present application is described.

[0089] As shown in Figure 1 and Figure 2 The refrigerator 100 according to the first aspect of the present application includes a first storage compartment 1, a second storage compartment 2, an air duct structure 8, and an air duct 3.

[0090] Specifically, the second storage compartment 2 and the first storage compartment 1 are arranged along a first direction (e.g., the left-right direction as shown in Figure 1 The air duct structure 8 is provided on a housing 12 of the first storage compartment 1, and the air duct structure 8 and the housing 12 together define a refrigeration air duct 81, which is in communication with the interior of the first storage compartment 1. The air duct 3 is connected to the first storage compartment 1 and the second storage compartment 2 at both ends, and is in communication with the interior of the second storage compartment 2 and the refrigeration air duct 81, respectively.

[0091] For example, in Figure 1 and Figure 2In the example of the first and second storage chambers 1 and 2, the right end of the air duct 3 is connected to the first storage chamber 1, and the left end of the air duct 3 is connected to the second storage chamber 2. The air duct structure 8 is arranged on the inner side of the shell 12. The cold air in the second storage chamber 2 enters the refrigeration air duct 81 through the air duct 3, and then enters the interior of the first storage chamber 1 along the refrigeration air duct 81 to provide cold energy to the interior of the first storage chamber 1. The first storage chamber 1 can be a refrigeration chamber for preserving food. The second storage chamber 2 can be a freezing chamber for freezing food, but is not limited thereto. In this way, the cold air in the second storage chamber 2 can be transmitted to the first storage chamber 1 along the refrigeration air duct 81 through the air duct 3, which facilitates refrigeration of the first storage chamber 1, thereby improving the refrigeration effect of the first storage chamber 1. It should be noted that the air duct 3 further comprises other components for connecting or closing the air duct 3. The fan 9 in the second storage chamber 2 is arranged in the middle of the second storage chamber 2. The air duct 3 is arranged obliquely upward, so that the top of the first storage chamber 1 has more cold energy.

[0092] In combination with Figure 1 , Figure 2 and Figure 3 , the refrigerator 100 further comprises a first connecting structure 7 arranged at one end of the air duct 3, and the air duct 3 is detachably connected to the shell 12 and the air duct structure 8 through the first connecting structure 7. For example, in the examples of Figure 1 and Figure 2 , the first connecting structure 7 is arranged at the right end of the air duct 3, and the air duct 3 can be detachably connected to the shell 12 and the air duct structure 8 through the first connecting structure 7.

[0093] Thus, by arranging the first connecting structure 7, the air duct 3 can be connected with the shell 12, improving the connection sealing of the air duct 3 and the shell 12, avoiding the leakage of cold air when passing through the connection between the air duct 3 and the shell 12, thereby avoiding the occurrence of condensation or frost, and further enabling the refrigerator 100 to be normally used for a long time. In addition, the air duct 3 is connected with the air duct structure 8, enabling the air duct 3 to be tightly connected with the air duct structure 8, so that the air duct structure 8 is also tightly matched with the inner side of the shell 12, avoiding overflow when foaming between the air duct structure 8 and the shell 12, thereby avoiding affecting the installation of other components in the refrigerator 100, and facilitating the normal installation of the refrigerator 100. In addition, the air duct 3 can be connected with the shell 12 and the air duct structure 8 through one component (such as the first connecting structure 7), that is, the air duct 3 is connected with the shell 12 and the air duct structure 8 through the first connecting structure 7, without the need to arrange other components to fix the air duct structure 8 on the shell 12, thereby increasing the space utilization rate in the first storage compartment 1 and being more conducive to the arrangement and installation of the air duct structure 8. Moreover, the first connecting structure 7 is small, reducing the occupied space of the first connecting structure 7 in the refrigerator 100, facilitating the installation of other components in the refrigerator 100, thereby reducing the production difficulty of the refrigerator 100, and further improving the production efficiency of the refrigerator 100.

[0094] According to the refrigerator 100 of the utility model, the first connecting structure 7 on the air duct 3 can not only tightly connect the air duct 3 and the shell 12, avoiding the leakage of cold air, thereby avoiding the occurrence of condensation or frost, but also tightly connect the air duct 3 and the air duct structure 8, avoiding overflow when foaming, thereby enabling the refrigerator 100 to be normally used for a long time. In addition, the air duct 3 can be connected with the shell 12 and the air duct structure 8 through the first connecting structure 7, without the need to arrange other components to fix the air duct structure 8 on the shell 12, thereby being more conducive to the arrangement and installation of the air duct structure 8. Moreover, the first connecting structure 7 also reduces the occupied space in the refrigerator 100, facilitating the installation of other components in the refrigerator 100, thereby reducing the production difficulty of the refrigerator 100, and further improving the production efficiency of the refrigerator 100.

[0095] According to some embodiments of the utility model, referring to Figure 3-1 and Figures 4-6The air duct structure 8 is located inside the shell 12, at least one opening 121 is formed on the shell 12, at least one avoiding part 82 is arranged on the air duct structure 8, the avoiding part 82 is opposite to the opening 121, and a connecting piece 83 is arranged on the side wall of the avoiding part 82. One end of the first connecting structure 7 is connected with the end face of one end of the air pipe 3, the other end of the first connecting structure 7 is matched at the avoiding part 82 through the opening 121, the first connecting structure 7 is formed with a first matching groove 71, and the first connecting structure 7 has a fixing part 72. When the first connecting structure 7 is matched at the avoiding part 82, the fixing part 72 is abutted against the inner wall surface of the shell 12, and the connecting piece 83 is matched in the first matching groove 71.

[0096] For example, in the examples of Figure 3-1 and Figures 4-6 , the outer periphery of the air duct structure 8 is abutted against the inside of the shell 12, and the inner periphery of the air duct structure 8 is spaced apart from the shell 12, so that a refrigeration air duct 81 is formed. The opening 121 penetrates the shell 12 in the front-rear direction, and the avoiding part 82 is opposite to the opening 121 in the front-rear direction. The rear end of the first connecting structure 7 is connected with the right end face of the air pipe 3, and the front end of the first connecting structure 7 is matched at the avoiding part 82 through the opening 121.

[0097] In this way, after the first connecting structure 7 passes through the opening 121, the fixing part 72 is abutted against the shell 12, the connection between the air pipe 3 and the first storage compartment 1 is realized, the installation is simple, and therefore the installation efficiency of the air pipe 3 and the first storage compartment 1 is improved, and the production efficiency of the refrigerator 100 is further improved. In addition, after the first connecting structure 7 passes through the opening 121, the connecting piece 83 is matched in the first matching groove 71, the first connecting structure 7 is connected with the connecting piece 83, that is, the connection between the air pipe 3 and the air duct structure 8 is realized, the installation is simple, and therefore the installation efficiency of the air pipe 3 and the air duct structure 8 is improved, and the production efficiency of the refrigerator 100 is further improved. In addition, the fastening of the right end of the air pipe 3 is improved, the sealing between the air pipe 3 and the first storage compartment 1 is improved, and condensation is avoided. The air pipe 3 clamps the air duct structure 8, the air duct structure 8 is closely matched with the shell 12, overflow is avoided during foaming, and therefore the use performance and the aesthetics of the refrigerator 100 are improved. It should be noted that the fixing part 72 and the first matching groove 71 are not in the same side surface of the first connecting structure 7, and therefore the mutual influence is avoided. The first connecting structure 7 and the opening 121 are respectively provided with a plurality of (for example, two) avoiding parts 82, the two first connecting structures 7 are arranged in the up-down direction, and the two openings 121 are arranged in the up-down direction. The number and arrangement mode of the first connecting structure 7 and the opening 121 can be specifically set according to actual application, but are not limited thereto.

[0098] According to some embodiments of the present application, referring to Figure 3 and Figure 6The first connecting structure 7 comprises a main section 73, one end of the main section 73 is connected with one end face of the air duct 3, the other end of the main section 73 extends towards the air duct structure 8 and is connected with one end of the fixed section 72, and the other end of the fixed section 72 extends obliquely towards the side away from the main section 73 from the direction of the other end of the main section 73 towards the one end of the main section 73. For example, in the examples of Figure 3 and Figure 6 , the rear end of the main section 73 is connected with the above-mentioned one end face of the air duct 3, the front end of the main section 73 extends in the forward direction, the front end of the main section 73 is connected with the front end of the fixed section 72, and the fixed section 72 is located on the upper side or the lower side of the main section 73. The rear end of the fixed section 72 extends in the direction away from the main section 73 from the front to the rear direction. In this way, during the process that the first connecting structure 7 passes through the opening 121, the rear end of the fixed section 72 passes through the opening 121 smoothly and slides into the inner side of the shell 12, thereby improving the smoothness of the assembly of the first connecting structure 7 and the shell 12 and improving the assembly efficiency. In addition, after the first connecting structure 7 passes through the opening 121, the end face of the rear end of the fixed section 72 abuts against the inner side face of the shell 12 at the edge of the opening 121, thereby avoiding the first connecting structure 7 from falling off, i.e. avoiding the right end of the air duct 3 from falling off the shell 12, thereby improving the connection stability and the sealing performance of the air duct 3 and the shell 12. In addition, the fixed section 72 and the main section 73 are simple in structure and easy to process, thereby improving the production efficiency of the first connecting structure 7 and the air duct 3.

[0099] According to some embodiments of the present application, referring to Figure 3 and Figure 6 , the other end of the fixed section 72 extends obliquely from the direction of the one end of the main section 73 towards the other end of the main section 73. For example, in the examples of Figure 3 and Figure 6 , the rear end of the fixed section 72 extends obliquely in the direction away from the main section 73 from the rear to the front direction. In this way, during the process that the first connecting structure 7 passes through the opening 121, the rear end of the fixed section 72 passes through the opening 121 smoothly and slides into the inner side of the shell 12, thereby further improving the smoothness of the assembly of the first connecting structure 7 and the shell 12 and further improving the assembly efficiency.

[0100] Further, referring to Figure 3 and Figure 6 , the other end face of the fixed section 72 is provided with a plurality of stepped faces 721 arranged in the extending direction thereof, and when the other end of the first connecting structure 7 is fitted at the avoiding section 82, one of the plurality of stepped faces 721 abuts against the inner wall face of the shell 12. In the description of the present application, the meaning of "a plurality of" is two or more than two.

[0101] For example, in the examples of Figure 3And Figure 6 In the example of the fixed portion 72, the rear end surface of the fixed portion 72 is stepped, and a plurality of step surfaces 721 are arranged in sequence along the direction of the rear end surface of the fixed portion 72. When the other end of the first connecting structure 7 is fitted at the avoiding portion 82, the fixed portion 72 is entirely fitted in the inner wall surface of the shell 12 when the thickness of the shell 12 is small. When the other end of the first connecting structure 7 is fitted at the avoiding portion 82, one of the plurality of step surfaces 721 is in abutment with the inner wall surface of the shell 12 when the thickness of the shell 12 is large. The front side step surface 721 of one of the plurality of step surfaces 721 is located in the inner wall surface of the shell 12, and the rear side step surface 721 of one of the plurality of step surfaces 721 is located between the side wall of the opening 121 and the main body section 73. In this way, the first connecting structure 7 is suitable for fitting with the shell 12 within a certain thickness range, that is, the air duct 3 is suitable for tightly fitting with the shell 12 of the first storage compartment 1 of different thicknesses, improving the applicability of the air duct 3. In addition, the air duct 3 is tightly fitted with the shell 12, which not only realizes the seal-free connection of the air duct 3 and the shell 12, but also improves the installation efficiency on site and the production efficiency of the refrigerator 100. The air duct 3 and the shell 12 can also be clamped in place, improving the fitting precision of the air duct 3 and the shell 12 and avoiding air leakage. It should be noted that the shell 12 is a plastic suction molded part, and the characteristics of the manufacturing process result in the thickness of the shell 12 within a range of values.

[0102] According to some embodiments of the present application, referring to Figure 3 And Figure 6 The fixed portion 72 is provided in a plurality of fixed portions 72, and the plurality of fixed portions 72 are respectively arranged on both sides of the first fitting groove 71. For example, in the example of Figure 3 And Figure 6 The fixed portion 72 is provided with two fixed portions 72, and the two fixed portions 72 are respectively located on the front and rear sides of the main body section 73. In this way, the plurality of fixed portions 72 are in abutment with the inner wall of the shell 12 at the same time, further improving the assembly strength of the first connecting structure 7 and the shell 12, further preventing the air duct 3 from falling off the shell 12, and further improving the installation stability of the air duct 3 and the first storage compartment 1. In addition, the plurality of fixed portions 72 are in abutment with the inner wall of the shell 12 from the opposite sides of the main body section 73 at the same time, improving the assembly stability of the first connecting structure 7 and the shell 12, and improving the assembly stability of the first connecting structure 7 and the connecting piece 83, thereby improving the connection stability of the air duct 3 and the shell 12 and the air duct structure 8, respectively, so that the air duct 3 can be used normally for a long time.

[0103] Optionally, the fixing portion 72 is an elastic member. Thus, the fixing portion 72 is elastic, and during assembly of the first connecting structure 7 and the shell 12, the fixing portion 72 is deformed by extrusion of the sidewall of the opening 121, the rear end of the fixing portion 72 moves towards the main body segment 73, the first connecting structure 7 is facilitated to pass through the opening 121, and the first connecting structure 7 is facilitated to be assembled with the shell 12. After the first connecting structure 7 and the shell 12 are assembled, the fixing portion 72 rebounds to the original position, the rear end of the fixing portion 72 abuts against the inner wall surface of the shell 12, the stability of the assembly of the first connecting structure 7 and the shell 12 is improved, and the air duct 3 is prevented from falling off the shell 12.

[0104] According to some embodiments of the present application, referring to Figure 3-1 , Figure 4 and Figure 5 , the first matching groove 71 is formed on the side of the main body segment 73 facing the connecting piece 83. The connecting piece 83 comprises a supporting segment 831 and a matching segment 832, one end of the supporting segment 831 is connected with the sidewall of the avoiding portion 82, the other end of the supporting segment 831 extends towards the side where the air duct 3 is located, the matching segment 832 is connected with the other end of the supporting segment 831, the cross-sectional area of the matching segment 832 is greater than that of the supporting segment 831, and the matching segment 832 is matched in the first matching groove 71.

[0105] For example, in the examples of Figure 3-1 , Figure 4 and Figure 5 , the first matching groove 71 is formed on the right side of the main body segment 73. The front end of the supporting segment 831 (i.e. one end of the supporting segment 831) is connected with the sidewall of the avoiding portion 82, and the rear end of the supporting segment 831 (i.e. the other end of the supporting segment 831) extends rearward. The right end of the matching segment 832 is connected with the rear end of the supporting segment 831. The cross section of the matching segment 832 and the cross section of the supporting segment 831 are in a plane perpendicular to the front-rear direction. The left end of the matching segment 832 is matched in the first matching groove 71. In this way, the structure of the connecting piece 83 is simple, easy to form and process, thereby improving the production efficiency of the connecting piece 83 and the production efficiency of the refrigerator 100. In addition, the assembly mode of the connecting piece 83 and the first matching groove 71 is simple, and the connecting piece 83 and the first matching groove 71 are quickly matched, thereby improving the assembly efficiency of the air duct 3 and the air duct structure 8, and further improving the assembly efficiency of the refrigerator 100.

[0106] According to some embodiments of the present application, referring to Figure 2 and Figure 3-1The matching section 832 has a first side surface 8321 and a second side surface 8322 connected to the first side surface 8321, the first side surface 8321 is in abutment with the side wall of the first matching groove 71, and the second side surface 8322 is located on the side of the first side surface 8321 away from the supporting section 831 and is inclined to extend from the supporting section 831 to the matching section 832 and to extend from the first connecting structure 7 to the direction away from the first connecting structure 7.

[0107] For example, in the example of Figure 2 and Figure 3-1 , the first side surface 8321 is the front side surface of the matching section 832, the second side surface 8322 is the rear side surface of the matching section 832, and the left side of the first side surface 8321 and the left side of the second side surface 8322 are connected. In the direction from front to back, the second side surface 8322 is inclined to extend from the first connecting structure 7 to the direction away from the first connecting structure 7. In this way, during the assembly of the first connecting structure 7 and the shell 12, the first connecting structure 7 moves forward, the second side surface 8322 is inclined to facilitate the smooth movement of the first connecting structure 7 forward, and the first connecting structure 7 is easily matched with the matching section 832, thereby improving the assembly efficiency of the first connecting structure 7 and the connecting piece 83 and improving the assembly efficiency of the air duct structure 8 and the air duct structure 8.

[0108] Optionally, the connecting piece 83 is a resilient piece. Thus, the connecting piece 83 has elasticity, and during the assembly of the first connecting structure 7 and the shell 12, the first connecting structure 7 extrudes the matching section 832 of the connecting piece 83, the connecting piece 83 deforms, the rear end of the connecting piece 83 moves to the direction close to the main body section 73, and the side wall of the first matching groove 71 passes through the matching section 832. After the assembly of the first connecting structure 7 and the shell 12 is completed, the rear end of the connecting piece 83 rebounds to the original position, so that the matching section 832 of the connecting piece 83 is in abutment with the side wall of the first matching groove 71, thereby improving the stability and sealing performance of the assembly of the first connecting structure 7 and the air duct structure 8 and improving the installation stability of the air duct structure 8.

[0109] Optionally, referring to Figure 3-1 , the air duct structure 8 comprises a decorative plate 84, a cover plate 85 and a foam plate 86. The decorative plate 84 is located on the side of the air duct structure 8 facing the first storage compartment 1, the foam plate 86 is located on the side of the air duct structure 8 facing the shell 12, and the cover plate 85 is located between the decorative plate 84 and the foam plate 86. Thus, the decorative plate 84 can be used to decorate the air duct structure 8, and the appearance of the interior of the refrigeration compartment is also improved. In addition, the cover plate 85 improves the structural strength of the air duct structure 8, thereby prolonging the service life of the air duct structure 8. In addition, the foam plate 86 can be used for heat preservation, thereby avoiding the diffusion of cold energy.

[0110] According to some embodiments of the present application, referring to Figure 1 and Figure 7The air duct 3 comprises a first shell 31 and a second shell 32, two ends of the first shell 31 are detachably connected with the first storage chamber 1 and the second storage chamber 2 respectively. The second shell 32 is located on the side of the first shell 31 facing the center of the refrigerator 100, the second shell 32 and the first shell 31 jointly define a passage 35, the passage 35 is in communication with the refrigeration air duct 81 and the interior of the second storage chamber 2 respectively, and the first connecting structure 7 is arranged on the end face of the second shell 32 facing the first refrigeration chamber.

[0111] For example, in the example of Figure 1 and Figure 7 , the right end of the first shell 31 is detachably connected with the outer side wall of the first storage chamber 1, and the left end of the first shell 31 is detachably connected with the outer side wall of the second storage chamber 2. The first shell 31 is located on the rear side of the second shell 32, the first shell 31 and the second shell 32 are detachably connected, the right end of the second shell 32 is detachably connected with the outer side wall of the first storage chamber 1, and the left end of the second shell 32 is detachably connected with the outer side wall of the second storage chamber 2. Among them, the cold air can flow from the second storage chamber 2 to the first storage chamber 1 through the passage 35.

[0112] In this way, the right end of the air duct 3 is connected with the first storage chamber 1 through the first shell 31 and the second shell 32 respectively, and the left end of the air duct 3 is connected with the second storage chamber 2 through the first shell 31 and the second shell 32 respectively, which strengthens the connection strength of the two ends of the air duct 3 with the first storage chamber 1 and the second storage chamber 2 respectively, avoids the air duct 3 from falling off from the first storage chamber 1 or the second storage chamber 2, improves the use stability of the air duct 3, and thus improves the safety performance of the refrigerator 100. In addition, the detachable connection facilitates the later maintenance of the refrigerator 100, reduces the difficulty of maintenance of the staff, and is convenient for the staff to maintain. In addition, the air duct 3 has a simple structure and is easy to process, thereby improving the production efficiency of the air duct 3, and the first shell 31 and the second shell 32 of the same end of the air duct 3 are connected, thereby further improving the sealing performance of the connection, and achieving the sealing-free setting. It should be noted that the first shell 31 and the second shell 32 can be connected by a buckle, but are not limited thereto.

[0113] Among them, as Figure 1 and Figure 7As shown, one end surface of the first shell 31 (i.e. the surface of the right end of the first shell 31 facing the first storage chamber 1) and one end surface of the second shell 32 (i.e. the surface of the right end of the second shell 32 facing the first storage chamber 1) jointly constitute a first mating surface 33, and the first sealing member 4 is bonded to the first mating surface 33. The other end surface of the first shell 31 (i.e. the surface of the left end of the first shell 31 facing the second storage chamber 2) and the other end surface of the second shell 32 (i.e. the surface of the left end of the second shell 32 facing the second storage chamber 2) jointly constitute a second mating surface 34, and the second sealing member 5 is bonded to the second mating surface 34. In this way, the first sealing member 4 can be connected to the one end surface of the first shell 31 and the second shell 32 at the same time, and the second sealing member 5 can be connected to the other end surface of the first shell 31 and the second shell 32 at the same time, further strengthening the connection of the first shell 31 and the second shell 32, and further improving the stability of the use of the air pipe 3. In addition, the sealing performance of the connection of the first shell 31 and the second shell 32 with the first storage chamber 1 and the second storage chamber 2 respectively is also improved.

[0114] In combination Figure 8 and Figure 10 , one of the housing 12 and the first shell 31 is provided with a first clamping jaw 13, and the other of the housing 12 and the first shell 31 is formed with a first through hole 311, the first clamping jaw 13 is fitted in the first through hole 311, and the free end of the first clamping jaw 13 abuts against the side wall of the other of the housing 12 and the first shell 31.

[0115] For example, the first clamping jaw 13 and the first through hole 311 can be provided in the following ways: first, the first storage chamber 1 is provided with the first clamping jaw 13, the first shell 31 is formed with the first through hole 311, and the free end of the first clamping jaw 13 abuts against the side wall of the first shell 31 (as shown in Figure 10 ). Second, the first shell 31 is provided with the first clamping jaw 13, the first storage chamber 1 is formed with the first through hole 311, and the free end of the first clamping jaw 13 abuts against the side wall of the first storage chamber 1.

[0116] In Figure 8 and Figure 10In the example shown in Figure 1 and Figure 7 , along the width direction of the first shell 31, a plurality of first perforations 311 are arranged on the first shell 31 at intervals, and a plurality of first clamping claws 13 are arranged on the rear side wall of the first storage chamber 1 at intervals. For example, two first perforations 311 and two first clamping claws 13 are provided, and the first perforations 311 and the first clamping claws 13 correspond one by one, but the number and arrangement of the first perforations 311 and the first clamping claws 13 can be set according to actual use to meet actual needs.

[0117] In combination with Figure 13 and Figure 14 , the rear side wall of the shell 12 is provided with a second clamping claw 14, the side of the second clamping claw 14 facing the first shell 31 is formed with a clamping groove 141, the end of the first shell 31 facing the first storage chamber 1 is fitted in the clamping groove 141, and the free end of the second clamping claw 14 abuts against the side wall of the first shell 31.

[0118] For example, in the example shown in Figure 13 and Figure 14 , the free end of the second clamping claw 14 first extends away from the first storage chamber 1, and then extends from right to left. The free end of the second clamping claw 14 and the rear side wall of the first storage chamber 1 together define the clamping groove 141, and the right end of the first shell 31 is fitted in the clamping groove 141. In this way, the free end of the second clamping claw 14 limits the end of the first shell 31, preventing the first shell 31 from moving away from the first storage chamber 1, and preventing the first shell 31 from falling off the first storage chamber 1, thereby improving the stability of the installation of the air duct 3. As shown in Figure 13 , along the width direction of the first shell 31, a plurality of second clamping claws 14 are arranged on the rear side wall of the first storage chamber 1 at intervals, for example, two second clamping claws 14 are provided, but the number and arrangement of the second clamping claws 14 can be set according to actual use to meet actual needs.

[0119] According to the refrigerator 100 of the second aspect of the present application, referring to Figure 1 and Figure 7 , comprising a first storage room 1, a second storage room 2 and a duct 3, the second storage room 2 and the first storage room 1 are arranged along the first direction. The two ends of the duct 3 are respectively connected with the first storage room 1 and the second storage room 2.

[0120] For example, in the examples of Figure 1 and Figure 7 , the two ends of the duct 3 are respectively connected with the rear side of the first storage room 1 and the second storage room 2. Among them, the first storage room 1 can be a refrigeration room, which is used for fresh-keeping food. The second storage room 2 can be a freezer room, which is used for freezing food, but is not limited to this. In this way, the cold energy of the second storage room 2 can be transmitted to the first storage room 1 through the duct 3, which facilitates the refrigeration of the first storage room 1, thereby improving the refrigeration effect of the first storage room 1. It should be noted that other components are also provided in the duct 3, which are used to connect or close the duct 3.

[0121] Combined with Figure 7 and Figure 8 , the refrigerator 100 further comprises a first sealing piece 4 and a second sealing piece 5, the first sealing piece 4 is located between the one end face of the duct 3 and the first storage room 1, and the first sealing piece 4 is bonded with the one end face of the duct 3. And / or, the second sealing piece 5 is located between the other end face of the duct 3 and the second storage room 2, and the second sealing piece 5 is bonded with the other end face of the duct 3.

[0122] For example, the setting of the first sealing piece 4 and the second sealing piece 5 includes the following several cases: first, the first sealing piece 4 is located between the one end face of the duct 3 and the first storage room 1, and the first sealing piece 4 is connected with the one end face of the duct 3. Second, the second sealing piece 5 is located between the other end face of the duct 3 and the second storage room 2, and the second sealing piece 5 is connected with the other end face of the duct 3. Third, the first sealing piece 4 is located between the one end face of the duct 3 and the first storage room 1, and the first sealing piece 4 is connected with the one end face of the duct 3. And, the second sealing piece 5 is located between the other end face of the duct 3 and the second storage room 2, and the second sealing piece 5 is connected with the other end face of the duct 3.

[0123] Thus, the first seal 4 enhances the sealing of the connection between the one end of the air duct 3 and the first storage chamber 1, avoids the leakage of cold air from the connection, and avoids the condensation at the connection between the one end of the air duct 3 and the first storage chamber 1. The second seal 5 enhances the sealing of the connection between the other end of the air duct 3 and the second storage chamber 2, avoids the leakage of cold air from the connection, and avoids the condensation at the connection between the other end of the air duct 3 and the second storage chamber 2, so that the refrigerator 100 can be used normally for a long time. In addition, when the air duct 3 is installed with the first storage chamber 1 or the second storage chamber 2, the first seal 4 and the second seal 5 can be directly installed with the air duct 3, or the first seal 4 and the second seal 5 are directly installed with the first storage chamber 1 and the second storage chamber 2 respectively, which reduces the difficulty of installation of the first seal 4 and the second seal 5, thereby improving the installation efficiency of the refrigerator 100 and the production efficiency of the refrigerator 100. Moreover, the first seal 4 and the second seal 5 can move with the air duct 3, which is convenient for transportation and installation of the air duct 3, reduces the difficulty of installation of the first seal 4 and the second seal 5, and improves the installation efficiency of the refrigerator 100.

[0124] In addition, the first seal 4 and the second seal 5 have simple structures, and in the installation process, the one end of the air duct 3 is pressed against the first seal 4 after being matched with the first storage chamber 1, and the first seal 4 fills and seals the gap between the one end of the air duct 3 and the first storage chamber 1. The other end of the air duct 4 is pressed against the second seal 5 after being matched with the second storage chamber 2, and the second seal 5 fills and seals the gap between the other end of the air duct 3 and the second storage chamber 2. The sealing effect of the connection is improved, so that the connection between the air duct 3 and the first storage chamber 1 and the second storage chamber 2 can be free of sealing, compared with the traditional technology of using multiple adhesive tapes or multiple sponges, the sealing steps during installation are simplified, the installation time is shortened, and the production efficiency of the refrigerator 100 is improved.

[0125] According to some embodiments of the present application, the first sealing member 4 is a one-piece structure. And / or, the second sealing member 5 is a one-piece structure. For example, the first sealing member 4 and the second sealing member 5 are provided in the following ways: first, the first sealing member 4 is a one-piece structure. Second, the second sealing member 5 is a one-piece structure. Third, the first sealing member 4 is a one-piece structure, and the second sealing member 5 is a one-piece structure. In this way, the structural strength of the first sealing member 4 and the second sealing member 5 is improved, and the use performance of the first sealing member 4 and the second sealing member 5 is improved. In addition, compared with the conventional technology in which the left and right ends of the air pipe are sealed by multiple adhesive tapes, the first sealing member 4 and the second sealing member 5 can be used in one step, avoiding sealing in multiple steps, simplifying the sealing steps, and improving the installation efficiency. It should be noted that the first sealing member 4 and the second sealing member 5 can be sponge members, but are not limited thereto.

[0126] According to some embodiments of the present application, referring to Figure 8 and Figure 9 , one of the first storage chamber 1 and the second shell 32 is provided with a first buckle 321, and the other of the first storage chamber 1 and the second shell 32 is formed with a second matching groove 11, the second matching groove 11 is formed by the outer wall surface of the first storage chamber 1 or the side wall of the second shell 32 inwardly recessed, and the first buckle 321 is matched in the second matching groove 11.

[0127] For example, the first buckle 321 and the second matching groove 11 are provided in the following ways: first, the first buckle 321 is formed on the first storage chamber 1, and the second matching groove 11 is formed on the second shell 32. Second, the first buckle 321 is formed on the second shell 32, and the second matching groove 11 is formed on the first storage chamber 1 (as shown in Figure 8 and Figure 9 ). The right end of the second shell 32 is detachably connected with the first storage chamber 1 by matching the first buckle 321 in the second matching groove 11.

[0128] Thus, the difficulty of assembling and separating the second shell 32 and the first storage chamber 1 is reduced, the assembly efficiency of the second shell 32 and the first storage chamber 1 is improved, and the installation efficiency of the air pipe 3 and the first storage chamber 1 is improved. In addition, the first buckle 321 and the second matching groove 11 are simple in structure and are not affected by the thickness of the outer side wall of the first storage chamber 1 during assembly of the first buckle 321 and the second matching groove 11, so that the problem of difficult clamping caused by different thicknesses of the outer side walls of different models of the first storage chamber 1 in the refrigerator 100 is solved, thereby improving the universality of the air pipe 3 and improving the use performance of the air pipe 3. In addition, the installation mode of the first storage chamber 1 and the air pipe 3 is different from the traditional clamping structure, and the first step of installation of the air pipe 3 adopts a "hanging" mode, which can position the air pipe 3 in the first time and is simple to operate. It should be noted that a plurality of first buckles 321 are arranged on the second shell 32 in the width direction of the second shell 32, a plurality of second matching grooves 11 are formed at positions opposite to the plurality of first buckles 321 of the first storage chamber 1, for example, two first buckles 321 are arranged, two second matching grooves 11 are arranged, and the first buckles 321 and the second matching grooves 11 correspond to each other one by one. However, the number and arrangement mode of the first buckles 321 and the second matching grooves 11 can be specifically arranged according to actual use conditions to meet actual needs.

[0129] According to some other embodiments of the present application, referring to Figure 11 and Figure 12 , one of the first storage chamber 1 and the second shell 32 is provided with a second buckle 322, the free end of the second buckle 322 has a buckle portion 323, and the other of the first storage chamber 1 and the second shell 32 is formed with an opening 121, when the second buckle 322 is matched in the opening 121, the buckle portion 323 abuts against the side wall of the other of the first storage chamber 1 and the second shell 32.

[0130] For example, the arrangement of the second buckle 322 and the opening 121 includes the following cases: first, the second buckle 322 is arranged on the first storage chamber 1, the opening 121 is formed on the second shell 32, and the buckle portion 323 abuts against the side wall of the second shell 32. Second, the second buckle 322 is arranged on the second shell 32, the opening 121 is formed on the first storage chamber 1, and the buckle portion 323 abuts against the side wall of the first storage chamber 1 (as shown in Figure 12 ). Figure 11 and Figure 12In the example shown in FIG. 6, the second buckle 322 is formed on the side of the second shell 32 facing the first storage compartment 1 (i.e., the front side of the second shell 32). One end of the buckle portion 323 is connected to the end of the second buckle 322 away from the second shell 32 (i.e., the front end of the second buckle 322). The buckle portion 323 abuts against the front side of the outer side wall of the first storage compartment 1. When the second buckle 322 and the buckle portion 323 pass through the opening 121, the right end of the air duct 3 is pushed in a direction away from the buckle portion 323, so that at least a portion of the outer side wall of the first storage compartment 1 slides between the second shell 32 and the buckle portion 323.

[0131] In this way, the second shell 32 and the buckle portion 323 limit the side wall of the first storage compartment 1, so that the second shell 32 of the air duct 3 cannot fall off the first storage compartment 1, and the stability of the connection between the air duct 3 and the first storage compartment 1 is improved. In addition, the second buckle 322, the buckle portion 323, and the opening 121 have simple structures, and the air duct 3 and the first storage compartment 1 are easy to assemble, so that the installation efficiency of the refrigerator 100 is improved. In addition, the installation mode of the first storage compartment 1 and the air duct 3 is different from the traditional clamping structure, and the first installation of the air duct 3 uses a sliding rail installation mode, so that the position of the air duct can be positioned at the first time, and the operation is simple. It should be noted that, in the width direction of the second shell 32, a plurality of second buckles 322 and a plurality of buckle portions 323 are arranged on the second shell 32, a plurality of openings 121 are formed at positions opposite to the plurality of second buckles 322 of the first storage compartment 1, for example, two second buckles 322, two buckle portions 323, and two openings 121 are arranged, the second buckles 322 and the buckle portions 323 correspond to each other one by one, and the second buckles 322 and the openings 121 correspond to each other one by one. However, the number and arrangement mode of the second buckles 322, the buckle portions 323, and the openings 121 can be specifically set according to actual use conditions to meet actual needs.

[0132] Further, referring to Figure 11 and Figure 12 When the second buckle 322 is arranged on the end face of the second shell 32 close to the first storage compartment 1, the opening 121 is formed on the rear side wall of the first storage compartment 1, one end of the buckle portion 323 is connected to the end of the second buckle 322 away from the second shell 32, and the other end of the buckle portion 323 is first bent and extends toward one side of the second shell 32, and then bent and extends toward the side away from the second shell 32.

[0133] For example, in Figure 11 and Figure 12In the schematic example, one end of the buckle portion 323 is connected with the front end of the second buckle 322, the other end of the buckle portion 323 extends in a direction away from the second buckle 322, the distance between the other end of the buckle portion 323 and the second shell 32 is greater than the distance between the middle of the buckle portion 323 and the second shell 32, the middle of the buckle portion 323 abuts against the front side of the side wall of the first storage chamber 1, and the cross-sectional shape of the buckle portion 323 is approximately wave-shaped. In this way, the side wall of the first storage chamber 1 can be smoothly slid into the space between the second shell 32 and the buckle portion 323, thereby improving the assembly efficiency of the second shell 32 and the first storage chamber 1. In addition, the strength of the connection between the second buckle 322 and the buckle portion 323 is improved, and the connection between the second buckle 322 and the buckle portion 323 is prevented from breaking after long-term use, thereby enabling the second shell 32 and the first storage chamber 1 to be stably connected for a long time.

[0134] According to some embodiments of the present application, referring to Figure 13 and Figure 14 , the rear side wall of the first storage chamber 1 is provided with a limiting column 15, and the limiting column 15 and the second clamping jaw 14 are arranged along the width direction (for example, the up-down direction as shown in Figure 14 ) of the first shell 31, and the end of the first shell 31 facing the first storage chamber 1 is formed with a first limiting groove 312, and the limiting column 15 is fitted in the first limiting groove 312.

[0135] For example, in the examples of Figure 13 and Figure 14 , the limiting column 15 is approximately cylindrical in shape, and the inner wall of the first limiting groove 312 is in contact with at least a portion of the outer periphery of the limiting column 15. In this way, the limiting column 15 limits the first shell 31 from moving in the up-down direction, avoids the first shell 31 and the first storage chamber 1 from moving in the up-down direction after assembly, and improves the installation stability of the first shell 31. In addition, in cooperation with the second clamping jaw 14, the first shell 31 can be limited from different directions, thereby effectively improving the installation stability of the first shell 31, thereby facilitating the normal use of the air pipe 3 for a long time.

[0136] According to some embodiments of the present application, referring to Figure 15 and Figure 16 , the rear side wall of the second storage chamber 2 is provided with a protrusion 21, and the end of the first shell 31 facing the second storage chamber 2 is formed with a second through hole 313, and the protrusion 21 is fitted in the second through hole 313. For example, in the examples of Figure 15 and Figure 16In the example shown in FIG. 6, the protrusion 21 protrudes in a direction away from the rear side wall of the second storage chamber 2, and the protrusion 21 passes through the second through hole 313. In this way, the protrusion 21 cooperates with the second through hole 313 to limit the left end of the first shell 31 in the circumferential direction of the protrusion 21, avoiding the first shell 31 and the second storage chamber 2 from shaking in the circumferential direction of the protrusion 21 after assembly, thereby improving the assembly stability of the first shell 31 and the second storage chamber 2. Moreover, it is also conducive to the quick positioning of the other end of the air duct 3 and the second storage chamber 2, thereby improving the assembly efficiency of the air duct 3 and the second storage chamber 2. In addition, the protrusion 21 and the second through hole 313 have simple structure and are easy to process and assemble, thereby improving the assembly efficiency of the air duct 3 and the second storage chamber 2.

[0137] Optionally, referring to Figure 15 and Figure 16 , the free end face of the protrusion 21 is inclined in a direction away from the second storage chamber 2 in a direction from the first storage chamber 1 to the second storage chamber 2. For example, in the example shown in Figure 15 and Figure 16 , the free end face of the protrusion 21 is inclined and extends backward in a direction from left to right. In this way, the free end of the protrusion 21 is positioned relative to the second through hole 313, facilitating the protrusion 21 to quickly pass through the second through hole 313, thereby further improving the assembly efficiency of the first shell 31 and the second storage chamber 2, and further improving the assembly efficiency of the air duct 3 and the second storage chamber 2.

[0138] According to some embodiments of the present application, referring to Figure 15 and Figure 16 , a limiting protrusion 22 is arranged on the side surface of the second storage chamber 2 facing the first storage chamber 1, and one side of the second shell 32 in the width direction (such as the up-down direction shown in Figure 15 ) is formed with a second limiting groove 324, and the limiting protrusion 22 is fitted in the second limiting groove 324. For example, in the example shown in Figure 15 and Figure 16In the example, the limiting protrusion 22 is formed on the right side of the second storage chamber 2, and the second limiting groove 324 is formed on the lower side of the left end of the second outer shell 32. The inner wall of the second limiting groove 324 is roughly C-shaped. At least a portion of the upper end of the limiting protrusion 22 fits into the second limiting groove 324. With this configuration, the limiting protrusion 22 limits the second outer shell 32 through the second limiting groove 324, preventing the second outer shell 32 from detaching from the second storage chamber 2 in the front-to-back direction, thereby improving the assembly stability of the air duct 3 and the second storage chamber 2. In addition, the assembly status of the limiting protrusion 22 and the second limiting groove 324 can be used to determine whether the air duct 3 and the second storage chamber 2 are properly assembled, so that adjustments can be made during the assembly process to improve the assembly accuracy of the air duct 3 and the second storage chamber 2, and also achieve the effect of sealing-free assembly. The air duct 3 can be a plastic part. Since the volume of plastic parts is smaller than that of foam parts, the influence of the air duct 3 on the flowability of the foam material can be reduced, thereby improving the foaming quality and further reducing costs.

[0139] Among them, combined Figures 8-16 One end of the air duct 3 is detachably connected to the first storage chamber 1 through the second connecting structure 6. The second storage chamber 1 is provided with a protrusion 21, and the other end of the air duct 3 is formed with a second through hole 313. The protrusion 21 fits into the second through hole 313.

[0140] For example, the right end of the duct 3 is detachably connected to the first storage chamber 1 via a second connecting structure 6. The second connecting structure 6 can be implemented in various ways. For example, as... Figures 8-10 As shown, the second connecting structure 6 includes a first claw 13, a first through hole 311, a first latch 321, and a second mating groove 11. The first claw 13 is disposed on the rear side wall of the first storage chamber 1, and the first through hole 311 is formed on the rear side wall of the right end of the air duct 3. The free end of the first claw 13 passes through the first through hole 311 and abuts against the side wall of the air duct 3. The first latch 321 is disposed on the front side wall of the right end of the air duct 3, and the second mating groove 11 is formed on the side wall of the first storage chamber 1. The first latch 321 engages in the second mating groove 11. That is, through the engagement of the first claw 13 with the first through hole 311 and the engagement of the first latch 321 with the second mating groove 11, the right end of the air duct 3 is detachably connected to the first storage chamber 1.

[0141] Or, such as Figures 11-14As shown, the second connecting structure 6 includes a second buckle 322, a buckle portion 323, an opening 121, a second clamping jaw 14, a limiting column 15 and a first limiting groove 312. The second buckle 322 is arranged on the front side wall of the right end of the air duct 3, one end of the buckle portion 323 is connected with the end of the second buckle 322 away from the air duct 3, the opening 121 is formed on the rear side wall of the first storage compartment 1, and when the second buckle 322 is fitted in the opening 121, the buckle portion 323 is abutted with the side wall of the first storage compartment 1. The second clamping jaw 14 is formed on the rear side wall of the first storage compartment 1, and the side of the second clamping jaw 14 facing the air duct 3 is formed with a clamping groove 141, and the right end of the air duct 3 is fitted in the clamping groove 141. The limiting column 15 is formed on the rear side wall of the first storage compartment 1, and the limiting column 15 and the second clamping jaw 14 are arranged along the width direction of the air duct 3, and the first limiting groove is formed on the end of the air duct 3 facing the first storage compartment 1, and the limiting column 15 is fitted in the first limiting groove 1.

[0142] In this way, the connection strength of the right end of the air duct 3 and the first storage compartment 1 is enhanced through the second connecting structure 6, the air duct 3 is prevented from falling off the first storage compartment 1, and the use stability of the air duct 3 is improved. In addition, through the cooperation of the protrusion 21 and the second perforation 313, the left end of the air duct 3 is quickly positioned with the second storage compartment 2, the assembly efficiency of the air duct 3 and the second storage compartment 2 is improved, and the protrusion 21 limits the left end of the air duct 3, so that the left end of the air duct 3 is prevented from shaking, the assembly stability of the air duct 3 and the second storage compartment 2 is improved, and the use performance of the refrigerator 100 is improved. In addition, it is also beneficial to quickly position the left end of the air duct 3 and the second storage compartment 2, and the positioning is accurate.

[0143] In some examples of the present application, the installation process of the refrigerator 100 is as follows:

[0144] First, the first housing 31 and the second housing 32 are assembled into the air duct 3, the first sealing member 4 is bonded at the first fitting surface 33, and the second sealing member 5 is bonded at the second fitting surface 34.

[0145] Then, the right end of the air duct 3 is installed with the first storage chamber 1, wherein the two first clamping claws 13 and the two first perforations 311 are one-to-one corresponding in the front-rear direction, and the two first buckles 321 and the two second matching grooves 11 are one-to-one corresponding in the front-rear direction, and then the right end of the air duct 3 is pressed forward, so that the free end of the first clamping claw 13 abuts against the first shell 31, and the first buckle 321 is matched in the second matching groove 11. Or, the two first connecting structures 7 are respectively passed through the two openings 121, so that the first connecting structure 7 is matched with the corresponding connecting piece 83, that is, the connecting piece 83 is matched with the first matching groove 71. Or, the two second buckles 322 and the two buckle parts 323 are passed through the two openings 121 first, and then the air duct 3 is pushed upward to a suitable position, and then the right end of the first shell 31 is pressed forward, so that the right end of the first shell 31 is matched in the clamping groove 141 of the second clamping claw 14, the limiting column 15 is matched in the first limiting groove 312, and the installation of the right end of the air duct 3 with the first storage chamber 1 is completed. At this time, the position of the air duct 3 is determined.

[0146] Then, the staff holds the second storage chamber 2, pushes the two protrusions 21 into the two second perforations 313 respectively, checks whether the limiting protrusion 22 is embedded in the second limiting groove 324, and if so, the installation is completed. If not, the position of the air duct 3 and the second storage chamber 2 needs to be adjusted again until the limiting protrusion 22 is embedded in the second limiting groove 324.

[0147] After the above installation operation, the worker does not need to take the adhesive tape to seal the air duct 3 again at the connection between the first storage chamber 1 and the second storage chamber 2, and the two ends of the air duct 3 are locked by the above components (for example, the first clamping claw 13 and the first perforation 311, the first buckle 321 and the second matching groove 11, the second buckle 322, the buckle part 323 and the opening 121, the second clamping claw 14, the limiting column 15 and the first limiting groove 312, the protrusion 21 and the second perforation 313, the limiting protrusion 22 and the second limiting groove 324) of the first storage chamber 1 and the second storage chamber 2 respectively, to form a connection relationship that is not easy to loosen, so that the first sealing piece 4 and the second sealing piece 5 are compressed and filled in the matching surface of the two ends of the air duct 3 and the first storage chamber 1 and the second storage chamber 2 respectively, to achieve the purpose of free sealing, and to improve the problem of condensation on the back side of the refrigerator 100.
