[0052] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0053] The present disclosure provides an air supply assembly 100, see Figure 1 and Figure 2 The air supply assembly 100 includes an air supply front cover 1, an air supply rear cover 2 and a connecting member 3.

[0054] The shape of the air supply front cover 1 and the shape of the air supply rear cover 2 are adapted to each other. When assembling the air supply front cover 1 and the air supply rear cover 2, other components in the refrigerator will clamp the air supply front cover 1 and the air supply rear cover 2, thereby realizing assembly between the air supply front cover 1 and the air supply rear cover 2.

[0055] Furthermore, in the disclosed embodiment, the air supply front cover 1 and the air supply rear cover 2 are also connected by a connecting member 3. In this way, the connecting member 3 will further fix the assembly between the air supply front cover 1 and the air supply rear cover 2, thereby making the assembly of the air supply assembly 100 more stable, and it is less likely to produce a gap between the air supply front cover 1 and the air supply rear cover 2, thereby improving the sealing of the air supply assembly 100 and the stability of the flow of cold air in the air supply assembly 100, thereby improving the refrigeration effect of equipment using the air supply assembly 100 (for example, a refrigerator, etc.).

[0056] In the embodiment of the present disclosure, the connection structure between the air supply front cover 1, the air supply rear cover 2, and the connecting member 3 can be as follows: Figure 3 , Figure 4 , Figure 5 and Figure 6 The air supply front cover 1 has a first through hole 11 , the air supply rear cover 2 has a second through hole 21 , and the connecting member 3 includes a first reinforcing block 31 and a screw 32 .

[0057] The first reinforcement block 31 is located at a side of the air supply front cover 1 away from the air supply rear cover 2 , and has a first threaded hole 311 .

[0058] The positions of the first threaded hole 311 , the first through hole 11 , and the second through hole 21 correspond to each other, that is, the axis of the first threaded hole 311 , the axis of the first through hole 11 , and the axis of the second through hole 21 are collinear.

[0059] The screw 32 passes through the second through hole 21 and the first through hole 11 and is threadedly connected with the first threaded hole 311. That is, when assembling the air supply front cover 1 and the air supply rear cover 2, the screw 32 can be passed through the second through hole 21 and the first through hole 11 in sequence, and then inserted into the first threaded hole 311 to be connected with the internal thread of the first threaded hole 311, so as to match and connect the air supply front cover 1 and the air supply rear cover 2.

[0060] In this way, in addition to clamping the air supply front cover 1 and the air supply rear cover 2 through other components in the refrigerator to achieve assembly, the air supply front cover 1 and the air supply rear cover 2 in the air supply assembly 100 are also connected and fixed through the first reinforcement block 31 and the screws 32. The first reinforcement block 31 and the screws 32 can apply a mutual squeezing force to the air supply front cover 1 and the air supply rear cover 2, so that the air supply front cover 1 and the air supply rear cover 2 are tighter, thereby improving the assembly stability between the air supply front cover 1 and the air supply rear cover 2 in the air supply assembly 100 and the tightness between the two, thereby improving the flow stability of the cold air and further improving the refrigeration effect of the refrigerator.

[0061] In one possible implementation, the air supply front cover 1 can be a plastic part or a foam part. When the air supply front cover 1 is a foam part, since it is not easy to set an internal thread in the foam part, the first through hole 11 is directly set on the foam part, and then a first reinforcement block 31 with a first threaded hole 311 is set to achieve connection between the foam part and the air supply rear cover 2, thereby avoiding damage to the foam part due to the screws 32 and improving the firmness of the air supply assembly 100.

[0062] In a possible implementation, the surface of the air supply front cover 1 away from the air supply rear cover 2 may have a first groove 12 , the first through hole 11 is located at the bottom of the first groove 12 , and the first reinforcement block 31 is located in the first groove 12 .

[0063] In this way, the first groove 12 can preliminarily fix the position of the first reinforcement block 31, which is more conducive to the assembly of the connecting part 3 between the air supply front cover 1 and the air supply rear cover 2, improves the convenience of assembly, and avoids the loosening of the first reinforcement block 31 after assembly, thereby improving the stability of the air supply assembly 100.

[0064] In a possible implementation, the surface of the air supply rear cover 2 away from the air supply front cover 1 may have a second groove 22, the second through hole 21 is located at the bottom of the second groove 22, and the screw 32 passes through the second through hole 21 and the first through hole 11 and is threadedly connected with the first threaded hole 311.

[0065] In this way, the screw 32 can be prevented from protruding from the surface of the air supply rear cover 2, thereby affecting the clamping assembly of the air supply rear cover 2, thereby improving the stability of the air supply assembly 100. The second groove 22 can also initially locate the position of the screw 32, facilitating the assembly of the air supply assembly 100.

[0066] In a possible implementation, the air supply front cover 1 has a third groove 13 on its surface close to the air supply rear cover 2, one end of the first through hole 11 is located at the bottom of the third groove 13, and the other end of the first through hole 11 is located at the bottom of the first groove 12. The air supply rear cover 2 has a first protrusion 23, the protrusion direction of the first protrusion 23 is toward the air supply front cover 1, and the first protrusion 23 is embedded in the third groove 13. The second groove 22 is located on the surface of the first protrusion 23 away from the air supply front cover 1.

[0067] During assembly, after the air supply front cover 1 and the air supply rear cover 2 are assembled according to the adaptation structure of the two structures, the first protrusion 23 is just embedded in the third groove 13, and the shape of the first protrusion 23 is adapted to the shape of the third groove 13. Then, the screw 32 can be passed through the second through hole 21 and the first through hole 11 in sequence, and then inserted into the first threaded hole 311, and threadedly connected with the first threaded hole 311, thereby realizing the assembly of the air supply component 100.

[0068] Such a configuration can improve the convenience of assembly between the air supply front cover 1 and the air supply rear cover 2, and the first protrusion 23 is embedded in the third groove 13, which also improves the connection stability between the air supply front cover 1 and the air supply rear cover 2 in the vertical direction of the axis of the first through hole 11, avoids misalignment between the two and thus creates a gap, and improves the assembly stability of the air supply component 100.

[0069] In a possible implementation, the connecting member 3 may further include a second reinforcement block, which is located on the side of the air supply rear cover 2 away from the air supply front cover 1, and has a second threaded hole on the second reinforcement block, which corresponds to the position of the first threaded hole 311, and the screw 32 is located in the first threaded hole 311, the first through hole 11, the second through hole 21 and the second threaded hole, and the screw 32 is threadedly connected to the first threaded hole 311 and the second threaded hole.

[0070] It can be understood that when the air supply rear cover 2 has the above-mentioned structure of the second groove 22 and the first protrusion 23 , the second reinforcement block can be located in the second groove 22 .

[0071] With such arrangement, when assembling the air supply component 100, the screw 32 can be first inserted into the second threaded hole and threadedly connected to the second threaded hole, and then the screw 32 can be rotated to pass through the second through hole 21 and the first through hole 11 in sequence, and then inserted into the first threaded hole 311 and threadedly connected to the first threaded hole 311, and then tightened, thereby realizing the connection between the air supply front cover 1 and the air supply rear cover 2.

[0072] In one possible implementation, the air supply rear cover 2 can be a plastic part or a foam part. When the air supply rear cover 2 is a foam part, a second reinforcement block is provided to prevent the air supply rear cover 2 from being damaged, thereby improving the strength of the air supply rear cover 2 and improving the assembly stability of the air supply component 100.

[0073] In the embodiment of the present disclosure, the shape of the first reinforcement block 31 and the shape of the second reinforcement block can be any reasonable shape, for example, they can be a rectangular structure, a cube structure, or a plate structure, etc. The shape of the first reinforcement block 31 and the shape of the second reinforcement block can be the same or different, and the embodiment of the present disclosure does not specifically limit this.

[0074] The structures of the above-mentioned connecting member 3 are only several possible structures listed, and it can also be any other reasonable structure, which is not limited in the embodiments of the present disclosure.

[0075] The number of the connecting parts 3 of the above structure provided on the air supply assembly 100 can be set as required. For example, two or three connecting parts can be provided to improve the tightness of the connection between the air supply front cover 1 and the air supply rear cover 2. The embodiment of the present disclosure does not limit this.

[0076] In the embodiment of the present disclosure, the air supply assembly 100 is used to transport cold air between various systems of the refrigerator. Of course, it can also be used to transport cold air between various systems in other devices other than the refrigerator. The embodiment of the present disclosure does not limit the application scenario of the air supply assembly 100. Below, taking the application of the air supply assembly 100 in the refrigerator as an example, the structure of the air supply assembly 100 is introduced:

[0077] See also Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 The side of the air supply front cover 1 close to the air supply rear cover 2 has a plurality of second protrusions 14 , and correspondingly, first recesses 15 can be formed between the plurality of second protrusions 14 .

[0078] A side of the air supply rear cover 2 close to the air supply front cover 1 has a plurality of third protrusions 24 , and correspondingly, second recesses 25 can be formed between the plurality of third protrusions 24 .

[0079] The positions of the second protrusions 14 correspond to the positions of the third protrusions 24, and the tops of the second protrusions 14 are in contact with the tops of the third protrusions 24. Correspondingly, the positions of the first recesses 15 correspond to the positions of the second recesses 25, and the first recesses 15 and the second recesses 25 are connected to form a channel for cold air circulation.

[0080] That is, when the air supply front cover 1 and the air supply rear cover 2 are assembled, the top ends of the multiple second protrusions 14 on the air supply front cover 1 fit with the top ends of the multiple third protrusions 24 on the air supply rear cover 2. At this time, the first recess 15 and the second recess 25 that correspond to each other are also connected, so that the first recess 15 and the second recess 25 together form a channel for the circulation of cold air.

[0081] The above-mentioned first through hole 11 can be located on the second protrusion 14, and the second through hole 21 can be located on the third protrusion 24. In this way, the penetration of the screw 32 can be prevented from affecting the air circulation in the channel, thereby improving the flow stability of the cold air in the air supply assembly 100, thereby improving the refrigeration effect of the refrigerator.

[0082] Furthermore, the connection position of the screw 32 is set at the position where the second protrusion 14 and the third protrusion 24 are in contact, which makes it easier to grasp the tightness of the screw 32 when assembling the screw 32, thereby avoiding the force applied by the screw 32 from causing deformation or damage to the air supply front cover 1 and the air supply rear cover 2, thereby improving the strength and stability of the air supply assembly 100.

[0083] In a possible implementation, when the air supply assembly 100 is provided with a first groove 12 , the position of the first groove 12 corresponds to the position of the second protrusion 14 .

[0084] When the air supply assembly 100 is provided with a second groove 22 , the position of the second groove 22 corresponds to the position of the third protrusion 24 .

[0085] When the air supply assembly 100 is provided with the third groove 13 and the first protrusion 23 , the third groove 13 is located on the second protrusion 14 , and the first protrusion 23 is located on the third protrusion 24 .

[0086] In a possible implementation, the channel may include a first air duct 4 and a second air duct 5, wherein the first air duct 4 is used to connect the freezing system 200 of the refrigerator with the refrigerating system 300 of the refrigerator, and the second air duct 5 is used to connect the freezing system 200 of the refrigerator with the temperature-changing system 400 of the refrigerator. In this way, since the temperature to be maintained in the freezing system 200 is usually lower than the temperature to be maintained in the refrigerating system 300 and the temperature-changing system 400, the cold air in the freezing system 200 is transported to the refrigerating system 300 and the temperature-changing system 400, and when the refrigerating system 300 or the temperature-changing system 400 reaches the required temperature, it can be controlled to stop the cold air from being transported thereto.

[0087] Understandably, Figure 7 The first recess 15 (4) shown is a first recess 15 for forming a first air duct 4. Figure 8The second recess 25 (4) shown refers to the second recess 25 used to form the first air duct 4. When the top of the second protrusion 14 is in contact with the top of the third protrusion 24, the positions of the first recess 15 (4) and the second recess 25 (4) correspond to and are connected to each other, thereby forming the first air duct 4.

[0088] Likewise, Figure 7 The first recess 15 (5) shown is the first recess 15 for forming the second air duct 5. Figure 8 The second recess 25 (5) shown refers to the second recess 25 used to form the second air duct 5. When the top of the second protrusion 14 is in contact with the top of the third protrusion 24, the positions of the first recess 15 (5) and the second recess 25 (5) correspond to each other and are connected, thereby forming the second air duct 5.

[0089] Figure 7 The first recess 15 (4) and the first recess 15 (5) are also used to indicate the positions of the first air duct 4 and the second air duct 5 on the air supply front cover 1, respectively. Figure 8 The second recess 25(4) and the second recess 25(5) shown are also used to indicate the positions of the first air duct 4 and the second air duct 5 on the air supply rear cover 2, respectively. In fact, the first air duct 4 is an air duct formed between the air supply front cover 1 and the air supply rear cover 2 after the two are assembled, and the second air duct 5 is also an air duct formed between the air supply front cover 1 and the air supply rear cover 2 after the two are assembled.

[0090] The first end 41 of the first air duct 4 and the first end 51 of the second air duct 5 are both used to communicate with the freezing system 200 of the refrigerator, wherein the first end 41 of the first air duct 4 and the first end 51 of the second air duct 5 may be connected to each other or not, which is not limited in the embodiment of the present disclosure.

[0091] The second end 42 of the first air duct 4 is used to communicate with the refrigeration system 300 of the refrigerator, thereby realizing a structure in which the first air duct 4 communicates with the freezing system 200 and the refrigeration system 300.

[0092] The second end 52 of the second air duct 5 is used to communicate with the temperature change system 400 of the refrigerator, thereby realizing a structure in which the second air duct 5 is connected with the freezing system 200 and the temperature change system 400.

[0093] In one possible implementation, see Fig. 9 and Fig.10 The air supply assembly 100 may also include a first electric damper 6 and a second electric damper 7 .

[0094] The first electric damper 6 is located at the second end 42 of the first air duct 4 and is in communication with the second end 42 of the first air duct 4, and is used to control the gas flow rate flowing through the second end 42 of the first air duct 4. That is, the second end 42 of the first air duct 4 and the refrigeration system 300 of the refrigerator are in communication with each other through the first electric damper 6, and the first electric damper 6 can control the flow rate of cold air flowing from the first air duct 4 into the refrigeration system 300, thereby adjusting the temperature in the refrigeration system 300 in real time.

[0095] The second electric damper 7 is located at the second end 52 of the second air duct 5 and communicated with the second end 52 of the second air duct 5, and is used to control the gas flow rate flowing through the second end 52 of the second air duct 5. That is, the second section 52 of the second air duct 5 and the temperature variable system 400 of the refrigerator are communicated through the second electric damper 7, and the second electric damper 7 can control the flow rate of cold air flowing from the second air duct 5 into the temperature variable system 400, thereby adjusting the temperature in the temperature variable system 400 in real time.

[0096] The embodiment of the present disclosure further provides a refrigerator, which includes any one of the air supply components 100 described above.

[0097] In one possible implementation, see Fig.11 and Fig.12 The refrigerator further includes a freezing system 200, a refrigerating system 300 and a temperature-changing system 400. The first end 41 of the first air duct 4 and the first end 51 of the second air duct 5 in the air supply assembly 100 are both connected to the freezing system 200, the second end 42 of the first air duct 4 is connected to the refrigerating system 300 through the first electric damper 6, and the second end 52 of the second air duct 5 is connected to the temperature-changing system 400 through the second electric damper 7.

[0098] The refrigerator also includes a control system, which is electrically connected to the first electric damper 6 and the second electric damper 7. The control system controls the temperature in the refrigeration system 300 by controlling the opening and closing degree of the first electric damper 6, and controls the temperature in the temperature variable system 400 by controlling the opening and closing degree of the second electric damper 7.

[0099] In addition to the above-mentioned structure, the refrigerator in the embodiment of the present disclosure may also include any other reasonable structure, which is not limited in the embodiment of the present disclosure.
