[0040] Please refer to Figure 1The utility model discloses a kind of air conditioners 500 provided in the embodiment, including heat exchanger 70, air duct baffle 40, connecting pipe 60 and protective sealing assembly 20.Air duct baffle 40 is equipped with through hole 401, connecting pipe 60 is connected heat exchanger 70 and is worn through through hole 401.Protective sealing assembly 20 includes protection 25 and sealing piece 23, protection 25 is sleeved on connecting pipe 60 and is worn through through hole 401, sealing piece 23 seals and connects protection 25 with air duct baffle 40.

[0041] In the above air conditioner 500, protection 25 is sleeved on connecting pipe 60 and is worn through through hole 401, so that protection 25 can separate the edge of connecting pipe 60 and through hole 401, to prevent the edge of through hole 401 from scratching connecting pipe 60, sealing piece 23 can seal and connect protection 25 with air duct baffle 40, to prevent air leakage of through hole 401, and to ensure the sealing effect of air duct 30 to some extent.

[0042] Specifically, air conditioner 500 can include heat exchanger 70, air duct 30 and connecting pipe 60.Heat exchanger 70 is arranged in air duct 30 of air conditioner 500, and is used for heat exchange. Figure 1 In one embodiment, heat exchanger 70 can be micro-channel heat exchanger 70.One end of connecting pipe 60 is connected with heat exchanger 70, for conveying refrigerant to heat exchanger 70 for heat exchange.

[0043] Taking the refrigeration mode of air conditioner 500 as an example, air enters air conditioner 500 through air inlet, is guided into heat exchanger 70 through air duct 30, and exchanges heat with refrigerant conveyed by connecting pipe 60 in heat exchanger 70, so that the temperature of air is reduced, and the processed cold air enters air outlet through air duct 30 and is sent back to indoor.

[0044] In related art, when the copper pipe of air conditioner needs to be worn through the through hole of air duct baffle, it is crucial to ensure the complete sealing of air duct and the effective protection of copper pipe, which not only requires to ensure that air duct will not leak due to the wearing of copper pipe, but also needs to avoid that copper pipe is scratched or worn by the metal edge of through hole in the wearing process.

[0045] In the embodiment of the application, please combine Figure 1 and Figure 2The air conditioner 500 comprises an air duct 30, an air duct partition plate 40 and a device bin 50, and the air duct partition plate 40 separates the air duct 30 and the device bin 50. The air duct partition plate 40 is provided with a through hole 401, and the connecting pipe 60 penetrates the through hole 401 and is connected to the heat exchanger 70 at one end and connected to other copper pipes in the device bin 50 at the other end. The protection and sealing assembly 20 comprises a protection piece 25 and a sealing piece 23. The protection piece 25 is sleeved on the connecting pipe 60 and penetrates the through hole 401 on the air duct partition plate 40, so that the outer wall of the connecting pipe 60 is not in direct contact with the inner wall of the through hole 401. The connecting pipe 60 is protected by the protection piece 25 and is less likely to be scratched by the edge of the through hole 401, thereby reducing the risk of wear and damage to a certain extent. The sealing piece 23 is used to seal the protection piece 25 and the air duct partition plate 40, so that the air in the air duct 30 cannot leak into the device bin 50 through the through hole 401, thereby ensuring the working performance of the air conditioner 500 to a certain extent.

[0046] In some embodiments, the length of the protection piece 25 is greater than the length of the through hole 401.

[0047] In this way, the protection piece 25 can completely cover the through hole 401 and extend beyond both ends of the through hole 401, thereby further preventing the connecting pipe 60 from being in direct contact with the edge of the through hole 401 and avoiding wear and damage.

[0048] Specifically, please refer to Figure 2 The protection piece 25 is sleeved on the connecting pipe 60 and penetrates the through hole 401. The length of the through hole 401 refers to the size of the through hole 401 in the penetrating direction of the protection piece 25, i.e., the distance between the side of the air duct partition plate 40 close to the heat exchanger 70 and the side far away from the heat exchanger 70. The length of the protection piece 25 is greater than the length of the through hole 401, so that after the protection piece 25 penetrates the through hole 401, the protection piece 25 can completely cover the through hole 401, and a part of the protection piece 25 will protrude from both sides of the through hole 401, thereby further preventing the connecting pipe 60 from being in direct contact with the edge of the through hole 401 and avoiding wear and damage to the connecting pipe 60.

[0049] In some embodiments, the sealing piece 23 is sleeved on the protection piece 25.

[0050] In this way, the sealing piece 23 is easy to assemble on the air conditioner 500.

[0051] Specifically, please refer to Figure 1 and Figure 2The sealing member 23 is sleeved on the protection member 25 away from the heat exchanger 70. In assembly, the sealing member 23 can be sleeved on the protection member 25 first, and when the protection member 25 is inserted through the through hole 401 of the air duct partition plate 40, the sealing member 23 is abutted on the side of the air duct partition plate 40 facing the heat exchanger 70, so that an effective seal is formed between the protection member 25 and the air duct partition plate 40, preventing air in the air duct 30 from leaking from the through hole 401, thereby affecting the working performance of the air conditioner 500.

[0052] In some embodiments, the protection member 25 is provided with a limiting portion 252, and the limiting portion 252 abuts the sealing member 23 and the air duct partition plate 40.

[0053] In this way, air leakage can be effectively prevented, and the sealing performance is enhanced to some extent.

[0054] Specifically, please refer to Figure 2 and Figure 3 The sealing member 23 is located between the limiting portion 252 and the air duct partition plate 40, and the sealing member 23 is sleeved on the end of the protection member 25 away from the heat exchanger 70. Optionally, the diameter of the limiting portion 252 is greater than the diameter of the through hole 401, and the diameter of the sealing member 23 is greater than the diameter of the through hole 401. When a part of the protection member 25 is inserted through the through hole 401, the limiting portion 252 and the sealing member 23 are abutted on the side of the air duct partition plate 40 facing the heat exchanger 70, so that the position of the protection member 25 on the air duct partition plate 40 is fixed. The limiting portion 252 and the air duct partition plate 40 clamp the sealing member 23, so that the sealing member 23 is extruded and deformed under the action of extrusion. Thus, the protection member 25 and the air duct partition plate 40 are sealed. The elastic material of the sealing member 23 expands outward when extruded, filling the gap between the limiting portion 252 and the air duct partition plate 40, so that the limiting portion 252 and the air duct partition plate 40 are effectively sealed, and to some extent, air in the air duct 30 cannot leak into the device compartment 50.

[0055] Optionally, please refer to Figure 2 The sealing member 23 can be an O-shaped sealing ring. The cross section of the O-shaped sealing ring is O-shaped or circular. When the O-shaped sealing ring is extruded by the limiting portion 252 of the protection member 25 and the air duct partition plate 40, it can extend and deform along the side of the limiting portion 252 away from the heat exchanger 70 and the side of the air duct partition plate 40 close to the heat exchanger 70, increasing the contact area and bonding force between the O-shaped sealing ring and the limiting portion 252 and the air duct partition plate 40, thereby further improving the sealing performance of the protection and sealing assembly 20, so that air in the air duct 30 is not easy to leak.

[0056] Optionally, in an embodiment, the limiting portion 252 is in the shape of a ring hexahedron, which is convenient for operation and installation by tools including but not limited to wrenches and the like.

[0057] In some embodiments, the protective sealing assembly 20 comprises a fastener 21, which is connected to the end of the protector 25 away from the heat exchanger 70 to fix the protective sealing assembly 20 on the air duct partition plate 40.

[0058] In this way, the protective sealing assembly 20 can be accurately positioned on the air duct partition plate 40 and fixedly connected to the air duct partition plate 40 through the connection of the fastener 21 and the protector 25.

[0059] Specifically, please refer to Figure 1 The end of the protector 25 away from the heat exchanger 70 is provided with a through hole 401, so that the limiting portion 252 of the protector 25 abuts against the air duct partition plate 40, and the fastener 21 is fixedly connected to the end of the protector 25 away from the heat exchanger 70, so that the air duct partition plate 40 is located between the limiting portion 252 and the fastener 21, thereby forming a stable fixing structure, so that the protective sealing assembly 20 can be accurately positioned on the air duct partition plate 40 and fixedly connected to the air duct partition plate 40, which can prevent the connection pipe 60 from loosening and the air duct 30 from leaking to a certain extent.

[0060] Optionally, when disassembling, the fastener 21 is separated from the protector 25, so that the protective sealing assembly 20 is separated from the air duct partition plate 40, thereby enabling the connection pipe 60 to be inspected and repaired. Therefore, the protective sealing assembly 20 is simple to install and convenient to inspect and repair.

[0061] In some embodiments, the end of the protector 25 away from the heat exchanger 70 is provided with a first external thread 256, the fastener 21 is provided with a first screw hole 212, the hole wall of the first screw hole 212 is provided with a first internal thread 212a, and the fastener 21 is connected to the protector 25 through the first external thread 256 and the first internal thread 212a.

[0062] In this way, the protective sealing assembly 20 can be fixed on the air duct partition plate 40 through the action of the threaded connection.

[0063] Specifically, please refer to Figure 2 and Figure 3 The connection pipe 60 can pass through the first screw hole 212 provided on the fastener 21, and the hole wall of the first screw hole 212 is provided with a first internal thread 212a matched with the first external thread 256 of the protector 25. When the first external thread 256 and the first internal thread 212a cooperate with each other, the fastener 21 can be tightly connected to the protector 25 by rotating the fastener 21. With the tightening of the fastener 21, the protector 25 and the sealing member 23 are fixedly connected to the air duct partition plate 40, thereby ensuring the sealing effect of the air duct 30 to a certain extent.

[0064] In some embodiments, the protection member 25 is provided with a clamping portion 254 at the end close to the heat exchanger 70, and the protection and sealing assembly 20 is provided with a locking member 29 which is connected to the clamping portion 254 and provides a clamping force to the clamping portion 254 for clamping the connecting pipe 60.

[0065] In this way, the clamping function of the clamping portion 254 and the locking function of the locking member 29 ensure the fixing and sealing effect of the connecting pipe 60 to a certain extent, preventing loosening and leakage.

[0066] Specifically, please refer to Figure 2 and Figure 3 The clamping portion 254 is located at the end of the protection member 25 close to the heat exchanger 70, and is used to fix and protect the connecting pipe 60, preventing loosening and leakage. Optionally, the clamping portion 254 can be a clamping claw, which includes a plurality of claw-shaped structures that can clamp around the connecting pipe 60, providing a relatively uniform clamping force, which can effectively clamp and fix the connecting pipe 60. The protection and sealing assembly 20 is provided with a locking member 29 which is tightly connected to the clamping portion 254 and located in the locking member 29. The locking member 29 can provide a clamping force to the clamping portion 254 for clamping the connecting pipe 60, so that the clamping portion 254 deforms towards the connecting pipe 60 to be firmly fixed on the connecting pipe 60, thereby ensuring the fixing and sealing effect of the connecting pipe 60 to a certain extent, preventing loosening and leakage.

[0067] In some embodiments, the side surface of the protection member 25 is provided with a second external thread 258, the locking member 29 is provided with a second screw hole 292, the hole wall of the second screw hole 292 is provided with a second internal thread 292a, the clamping portion 254 and the second external thread 258 are located in the through hole 401, and the second external thread 258 is connected with the second internal thread 292a to provide a clamping force to the clamping portion 254 by the locking member 29.

[0068] In this way, the clamping function of the clamping portion 254 and the locking function of the locking member 29 ensure the fixing and sealing effect of the connecting pipe 60 to a certain extent, preventing loosening and leakage.

[0069] Specifically, please refer to Figure 2 and Figure 3 The connecting pipe 60 can pass through the second screw hole 292 of the locking member 29, and the hole wall of the second screw hole 292 is provided with a second internal thread 292a which matches the second external thread 258 of the protection member 25. When the second external thread 258 and the second internal thread 292a cooperate with each other, by rotating the locking member 29, a tight thread connection between the locking member 29 and the protection member 25 can be formed. With the tightening of the locking member 29, the clamping portion 254 is firmly fixed on the connecting pipe 60, so that the clamping portion 254 generates a clamping force on the connecting pipe 60, thereby ensuring the protection and sealing effect of the protection and sealing assembly 20 on the connecting pipe 60 to a certain extent.

[0070] In some embodiments, the protective sealing assembly 20 comprises a sealing ring 27, which is sleeved on the connecting pipe 60 and located in the clamping portion 254.

[0071] In this way, the connecting pipe 60 can be better protected, and the sealing effect of the protective sealing assembly 20 can be further enhanced.

[0072] Specifically, please refer to Figure 2 and Figure 3 The sealing ring 27 is located between the connecting pipe 60 and the clamping portion 254, the shape of the sealing ring 27 matches the shape of the clamping portion 254, and the sealing ring 27 is sleeved on the connecting pipe 60. When the second external thread 258 of the protective piece 25 and the second internal thread 292a of the locking piece 29 are tightly connected by mutual cooperation, the clamping portion 254 provides a clamping force to the sealing ring 27, and the sealing ring 27 deforms under the action of the clamping force. The elastic material of the sealing ring 27 will expand outward when subjected to the clamping force, so that the sealing ring 27 clamps the connecting pipe 60, thereby better protecting the connecting pipe 60 and effectively sealing the connecting pipe 60 and the clamping portion 254, and further enhancing the sealing effect of the protective sealing assembly 20.

[0073] In some embodiments, the protective piece 25 is an integrally formed structure.

[0074] In this way, the integrally formed structure can reduce the installation components and provide better protection performance.

[0075] Specifically, please refer to Figure 2 The protective piece 25 adopts an integrally formed structure, that is, the protective piece 25 is completed by an integrally forming process in the manufacturing process, and the integrally forming process includes but is not limited to injection molding, die casting, stamping and the like. In this process, there is no additional welding, bonding or assembly step, so that the protective piece 25 has no joints or welding points, which can enhance the protection effect of the connecting pipe 60 to a certain extent. The integrally formed structure can reduce the installation components and simplify the installation steps to a certain extent.
