[0087] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0091] The present application proposes an air conditioner, which includes an air conditioner outdoor unit and an air conditioner indoor unit 1000, and a flexible connection component 1 that connects the air conditioner indoor unit 1000 and the air conditioner outdoor unit respectively. The air conditioner can be a split-type air conditioner that is easy for users to install personally. It uses a refrigerant pipe 11 to connect the indoor heat exchanger of the air conditioner indoor unit 1000 and the outdoor heat exchanger of the air conditioner outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by themselves, they only need to fix the air conditioner indoor unit 1000 and the air conditioner outdoor unit separately, without the need to assemble the refrigerant pipe 11 and add refrigerant, thereby reducing the difficulty of installation and enabling personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner of the present application can also be an ordinary split-type air conditioner or an integrated air conditioner.

[0092] Referring to Figures 1 to 5, in one embodiment of the present application, the air conditioner includes:

[0093] An air conditioner indoor unit 1000, an air conditioner outdoor unit, and a flexible connection assembly 1, wherein the flexible connection assembly 1 connects the air conditioner indoor unit 1000 and the air conditioner outdoor unit, and the flexible connection assembly 1 includes a refrigerant pipe 11 and a drain pipe 12;

[0094] The air-conditioning indoor unit 1000 includes a casing 2, a first fixing position 21 is provided on the outside of the casing 2, the flexible connection component 1 partially passes through the casing 2, and the first clamping member 3 fixes the flexible connection component 1 to the casing 2 at the first fixing position 21, and the drain pipe 12 is provided with a hard structure at the first fixing position 21, and the hard structure is used to radially support the drain pipe 12.

[0095] Specifically, the air conditioner includes an outdoor unit and an indoor unit 1000. The flexible connection assembly 1 connects the indoor unit 1000 and the outdoor unit, respectively. The flexible connection assembly 1 also includes a refrigerant pipe 11 and a drain pipe 12. The refrigerant pipes 11 are two inlet and outlet refrigerant pipes 11, respectively. One end of each refrigerant pipe 11 is connected to the indoor unit 1000, and the other end passes through the housing 2 of the indoor unit 1000 and connects to the outdoor unit. The drain pipe 12 has one end connected to the indoor unit 1000 and the other end passes through the housing 2 of the indoor unit 1000. It can be connected to the outdoor unit to cool the outdoor heat exchanger, or it can be directly connected to the outdoor space to directly discharge condensed water from the indoor unit 1000. After the refrigerant pipe 11 and the drain pipe 12 pass through the casing 2, if the refrigerant pipe 11 and the drain pipe 12 that have just passed through the casing 2 are not fixed, the refrigerant pipe 11 and the drain pipe 12 will swing left and right during the installation process, and there is a possibility of detaching from the air-conditioning indoor unit 1000, or affecting the installation of internal components of the air-conditioning indoor unit. Therefore, a fixed structure is often set near the point where the refrigerant pipe 11 and the drain pipe 12 pass through the casing 2, so that the section of the flexible connection component 1 that passes through the casing 2 is fixed outside the casing 2.

[0096] Therefore, a first fixing portion 21 is provided on the outside of the housing 2, and the first pressing member 3 secures the flexible connection assembly 1 to the housing 2 at the first fixing portion 21. The first fixing portion 21 is located near the exit of the flexible connection assembly 1, and the first pressing member 3 directly presses and secures the flexible connection assembly 1 to the outside of the housing 2, thereby facilitating the securement of the flexible connection assembly 1. However, because the drain pipe 12 is generally configured as a flexible hose, there is a risk that the drain pipe 12 may be flattened during the compression and securing process by the first pressing member 3, resulting in blockage of the drain pipe 12 and affecting the drainage of condensed water within the air conditioner indoor unit 1000.

[0097] Therefore, the drain pipe 12 is provided with a hard structure at the first fixing position 21, and the hard structure is used to radially support the drain pipe 12. This hard structure can provide radial support for the drain pipe 12, thereby ensuring that the first pressing member 3 presses the flexible connection assembly 1 at the first fixing position 21 and reducing the possibility of the drain pipe 12 being flattened.

[0098] In an embodiment of the present application, the hard structure is configured as a hard pipe section provided in the drain pipe 12, that is, the drain pipe 12 includes two flexible pipe sections and one hard pipe section, and the two flexible pipe sections are respectively connected to the opposite ends of the hard pipe section, and are respectively connected to the air-conditioning indoor unit 1000 and the air-conditioning outdoor unit.

[0099] In another embodiment of the present application, the rigid structure is configured as a rigid sleeve 13, which is mounted on the drain pipe 12. The rigid sleeve 13 is mounted on the outside of the drain pipe 12, thereby defining a radial installation space for the drain pipe 12. This connection facilitates the installation of the drain pipe 12. Furthermore, the rigid sleeve 13 is mounted only on a portion of the drain pipe 12 at the first fixing position 21, thereby ensuring the securement of the drain pipe 12 without affecting the bending of the flexible connection assembly 1 during installation.

[0100] The hard sleeve 13 can be configured as a hard metal pipe section, which is sleeved on the drain pipe 12 , and the inner diameter of the hard metal pipe section is slightly larger than the outer diameter of the drain pipe 12 .

[0101] In another embodiment of the present application, referring to Figures 1 and 2 , the rigid sleeve 13 is configured as a metal spring. This metal spring can be axially bent, allowing the rigid sleeve 13 to bend with the drain pipe 12, thereby facilitating the securement of the flexible connection assembly 1. In other embodiments, the rigid sleeve 13 can also be configured as a metal bellows section.

[0102] In this embodiment, the refrigerant tube 11 is configured as a metal bellows, and the outer portion of the bellows is sheathed with a braided mesh tube. This ensures the radial rigidity of the refrigerant tube 11, reduces the risk of the refrigerant tube 11 being crushed, facilitates bending of the refrigerant tube 11, and can withstand a certain amount of pressure to reduce the possibility of accidental bursting of the refrigerant tube 11. The outer portion of the braided mesh tube further protects the metal bellows. To facilitate the installation of the refrigerant tube 11, copper tubes are often installed at both ends of the metal bellows, and the metal bellows and the copper tubes are welded together.

[0103] The technical solution of the present application is to provide an air conditioner indoor unit 1000 and an air conditioner outdoor unit, with a flexible connection assembly 1 connecting the two units. The flexible connection assembly 1 includes a refrigerant pipe 11 and a drain pipe 12. The air conditioner indoor unit 1000 includes a housing 2, with a first fixing portion 21 provided on the outside of the housing 2. The flexible connection assembly 1 partially extends out of the housing 2, and a first pressing member 3 secures the flexible connection assembly 1 to the housing 2 at the first fixing portion 21. The first pressing member 3 directly presses and secures the flexible connection assembly 1 to the outside of the housing 2, thereby facilitating the securement of the flexible connection assembly 1. A rigid structure is provided at the first fixing portion 21 for radially supporting the drain pipe 12. The rigid structure provides radial support for the drain pipe 12, thereby ensuring that the first pressing member 3 compresses the flexible connection assembly 1 at the first fixing portion 21 and reducing the possibility of the drain pipe 12 being flattened.

[0104] Referring to Figures 1 and 2 , in the embodiment of the present application, the flexible connection assembly 1 further includes a sleeve 14 , the housing 2 defines a first mounting opening 22 for the refrigerant pipe 11 and the drain pipe 12 to pass through, and the housing 2 further defines a second fixing portion 23 on the outside thereof. The second fixing portion 23 is disposed on a side of the first fixing portion 21 adjacent to the first mounting opening 22 ;

[0105] The partial pipe sections of the refrigerant pipe 11 and the drain pipe 12 passing through the first installation opening 22 are fixed in the second fixing position 23 and the first fixing position 21 respectively. The sleeve 14 is sleeved on the refrigerant pipe 11 and the drain pipe 12 and is located on the side of the second fixing position 23 away from the first installation opening 22.

[0106] Specifically, the flexible connection component 1 also includes a sleeve 14, which is sleeved on the refrigerant pipe 11 and the drain pipe 12. The first clamping member 3 simultaneously presses the sleeve 14, and the refrigerant pipe 11 and the drain pipe 12 in the sleeve 14, that is, the end of the sleeve 14 close to the air-conditioning room is located before the first fixed position 21, so that the flexible connection component 1 forms an integral structure at the first fixed position 21, which can facilitate the fixation of the flexible connection component 1 and reduce the possibility of axial slippage of the sleeve 14 relative to the drain pipe 12 and the refrigerant pipe 11, thereby ensuring the fixing effect of the flexible connection component 1.

[0107] The casing 2 is provided with a first installation opening 22 for the refrigerant pipe 11 and the drain pipe 12 to pass through, that is, the refrigerant pipe 11 and the drain pipe 12 pass through the first installation opening 22 together, and the first fixing position 21 and the second fixing position 23 are both arranged close to the first installation opening 22, thereby fixing a section of the flexible connection component 1 close to the first installation opening 22, so as to reduce the possibility of the flexible connection component 1 in the air-conditioning indoor unit 1000 self-deviating as the air conditioner is installed, thereby reducing the possibility of the flexible connection component 1 detaching from the air conditioner.

[0108] The second fixing position 23 is arranged on the side of the first fixing position 21 close to the first mounting port 22, and the partial pipe sections of the refrigerant pipe 11 and the drain pipe 12 passing through the first mounting port 22 are fixed in turn at the second fixing position 23 and the first fixing position 21, thereby increasing the installation position of the refrigerant pipe 11 and the drain pipe 12 and the casing 2, and improving the fixing stability of the flexible connection component 1.

[0109] Because the refrigerant pipe 11 and the drain pipe 12 are not sleeved with the sleeve 14 at the second fixing position 23, and the drain pipe 12 is not provided with a hard structure, if a compression fixation method is adopted at this time, it is not convenient to fix the refrigerant pipe 11 and the drain pipe 12, and there is a risk of flattening the drain pipe 12.

[0110] In view of this, in an embodiment of the present application, a fixing block 4 is provided at the second fixing position 23. The fixing block 4 is provided with a first fixing groove 41 and a second fixing groove 42. The refrigerant tube 11 is clamped to the first fixing groove 41, and the drain tube 12 is clamped to the second fixing groove 42. Specifically, the fixing block 4 is provided with the first fixing groove 41 and the second fixing groove 42, and the refrigerant tube 11 is clamped to the first fixing groove 41, and the drain tube 12 is clamped to the second fixing groove 42, thereby achieving the separate fixing of the refrigerant tube 11 and the drain tube 12, thereby facilitating the fixing of the refrigerant tube 11 and the drain tube 12 and reducing the possibility of flattening the drain tube 12. The fixing block 4 is fixed to the outside of the casing 2. The fixing block 4 can be clamped to the casing 2, can be bonded to the casing 2, or can be connected to the casing 2 via fasteners.

[0111] The first fixing groove 41 and the second fixing groove 42 are often arranged on opposite sides of the fixing block 4 , thereby improving the rationality of the arrangement of the drainage pipe 12 and the refrigerant pipe 11 and reducing the cross-sectional area of ​​the flexible connection assembly 1 .

[0112] Because the ends of the metal bellows are welded to the copper tube, they may deform and expand due to the welding, making it difficult for the refrigerant tube 11 to fit into the first fixing groove 41. In the embodiment of the present application, referring to Figures 4 to 6, the first fixing groove 41 has a first open side 43, and the refrigerant tube 11 fits into the first fixing groove 41 from the first open side 43. The width of the first fixing groove 41 increases as it approaches the first open side 43. In other words, the first open side 43 of the first fixing groove 41 is configured to be open, thereby providing a certain degree of freedom for the installation of the refrigerant tube 11 and reducing the possibility of installation difficulties due to deformation of the refrigerant tube 11. In this case, to reduce the possibility of the refrigerant tube 11 falling out, the first fixing groove 41 is provided on the side of the fixing block 4 facing the housing 2, with the first open side 43 facing the housing 2.

[0113] Because the drain pipe 12 is configured as a flexible hose, to reduce the possibility of the drain pipe 12 falling out of the second fixing groove 42, in the embodiment of the present application, the second fixing groove 42 has a second open side 44. The drain pipe 12 is inserted into the second fixing groove 42 through the second open side 44, and the width of the second open side 44 is less than or equal to the diameter of the drain pipe 12. Specifically, the width of the second open side 44 is less than or equal to the diameter of the drain pipe 12, so that the edge of the second open side 44 can further prevent the drain pipe 12 from falling out. As can be seen in the accompanying drawings, the second open side 44 is formed by a mounting notch provided on one side of the second fixing groove 42.

[0114] Furthermore, referring to Figure 3 , a buffer member 26 is provided on the side of the second fixing portion 23 facing the fixing block 4. The buffer member 26 abuts between the fixing block 4 and the housing 2, thereby providing a cushioning effect for the fixing block 4 and preventing the refrigerant pipe 11 from directly contacting the housing 2. The buffer member 26 can be configured as a sponge sheet or a rubber sheet, and the buffer member 26 is directly bonded to the outside of the housing 2.

[0115] To facilitate the fixation of the fixing block 4, in the embodiment of the present application, the second fixing position 23 is further provided with a second pressing member 5. The second pressing member 5 presses the fixing block 4 at the second fixing position 23 to fix the drain pipe 12 and the refrigerant pipe 11. Specifically, the second pressing member 5 presses the fixing block 4 to the outside of the casing 2, thereby facilitating the installation of the fixing block 4 and the casing 2.

[0116] Furthermore, to reduce the possibility of the fixing block 4 moving relative to the second pressing member 5, in the embodiment of the present application, a retaining groove 45 is provided on the side of the fixing block 4 facing away from the housing 2, and the second pressing member 5 is snapped into the retaining groove 45. Specifically, the retaining groove 45 is provided on the side of the fixing block 4 facing away from the housing 2, and the second pressing member 5 is snapped into the retaining groove 45, thereby preventing the fixing block 4 from moving away from the second pressing member 5, thereby reducing the possibility of the second fixing position 23 failing to secure during use.

[0117] In order to facilitate the processing of the casing 2, the casing 2 includes two main casing parts and an installation casing part that are spliced ​​together. The first fixing position 21 and the second fixing position 23 are both provided on the installation casing part, so that the main casing part and the installation casing part are processed separately and then spliced ​​together again, thereby facilitating the processing of the casing 2.

[0118] Referring to Figures 1 to 5 , in the embodiment of the present application, the first fixing position 21 is provided with two first mounting seats 24 spaced apart from each other, the first pressing member 3 is configured as a first pressing hoop, and both ends of the first pressing hoop are respectively mounted on the two first mounting seats 24;

[0119] The second fixing position 23 is provided with two second mounting seats 25 spaced apart from each other. The second pressing member 5 is configured as a second pressing hoop, and both ends of the second pressing hoop are respectively mounted on the two second mounting seats 25 .

[0120] Specifically, the first fixing portion 21 includes two spaced-apart first mounting seats 24, located on opposite sides of the flexible connection assembly 1. One end of the first compression member 3 is mounted on one of the two first mounting seats 24, while the other end bypasses the flexible connection assembly 1 and is mounted on the other first mounting seat 24. This compresses the flexible connection assembly 1 against the first fixing portion 21, preventing the first compression member 3 from being directly mounted on the housing 2 and simplifying installation. The first mounting seats 24 can be bonded, snapped, or fastened to the housing 2 via fasteners; alternatively, the first mounting seats 24 can be integrally formed with the housing 2. The first compression member 3 is configured as a first compression clamp, and its shape should match that of the flexible connection assembly 1, thereby securing the flexible connection assembly 1 without exerting excessive pressure on it. In other embodiments, the first compression member 3 can also be configured as a cable tie, which, after tightening the flexible connection assembly 1, is secured to the first mounting seat 24.

[0121] The second fixing position 23 has two spaced-apart second mounting seats 25, located on opposite sides of the flexible connection assembly 1. One end of the second pressing member 5 is mounted on one of the two second mounting seats 25, while the other end bypasses the flexible connection assembly 1 and is mounted on the other second mounting seat 25. This compresses the flexible connection assembly 1 against the second fixing position 23, preventing the second pressing member 5 from being directly mounted on the housing 2 and reducing the difficulty of installing the second pressing member 5. The second mounting seats 25 can be bonded, snapped, or fastened to the housing 2 via fasteners; alternatively, the second mounting seats 25 can be integrally formed with the housing 2. The second pressing member 5 is configured as a second clamping hoop, and its shape should match that of the fixing block 4, thereby securing the flexible connection assembly 1 without exerting excessive pressure on the flexible connection assembly 1. In other embodiments, the second clamping member 5 can also be configured as a cable tie, which is secured to the fixing block 4 and then fixed to the second mounting seat 25.

[0122] To facilitate installation of the first clamping member 3, in the embodiment of the present application, a first pre-installation structure is provided on the first mounting seat 24, and the first clamping hoop and the first mounting seat 24 are secured together via a first fastener. Specifically, the first pre-installation structure provides a preliminary securement of the first clamping hoop and the first mounting seat 24, eliminating the need for additional securement of the first clamping hoop when the operator subsequently secures the first clamping hoop and the first mounting seat 24 via the first fastener, thereby facilitating installation of the first clamping hoop.

[0123] Furthermore, the first mounting structure includes two first clamping portions 241, respectively provided on the upper and lower sides of the first mounting base 24. The two first clamping portions 241 are respectively clamped to the upper and lower sides of the first compression clamp. Specifically, the two first clamping portions 241 are provided on the upper and lower sides of the first compression clamp to ensure the stability of the pre-fixation of the first compression clamp. The first clamping portions 241 are directly clamped to the edge of the first compression clamp, eliminating the need for corresponding clamping portions on the first compression clamp, thereby facilitating the processing of the first compression clamp.

[0124] The upper and lower extension directions of the first mounting seat 24 are along the axial direction of the flexible connection assembly 1. The first mounting opening 22 is typically installed at the lower end of the housing 2, and the flexible connection assembly 1 extends upward from the housing 2. Therefore, the upper and lower extension directions of the first mounting seat 24 are along the vertical direction of the air conditioner indoor unit 1000. In other embodiments, the first compression clamp and the first mounting seat 24 may be fixed only by the first fastener, or may be fixed only by clamping or bonding.

[0125] To facilitate installation of the first clamping member 3, in the embodiment of the present application, a second pre-installation structure is provided on the second mounting seat 25, and the second clamping clamp and the second mounting seat 25 are secured via a second fastener. Specifically, the second pre-installation structure provides a preliminary fixation of the second clamping clamp and the second mounting seat 25, eliminating the need for additional fixing of the second clamping clamp when the operator subsequently secures the second clamping clamp and the second mounting seat 25 via the second fastener, thereby facilitating installation of the second clamping clamp.

[0126] Furthermore, the second mounting structure includes two second clamping portions 251, respectively provided on the upper and lower sides of the second mounting base 25. The two second clamping portions 251 are respectively clamped to the upper and lower sides of the second compression clamp. Specifically, the two second clamping portions 251 are provided on the upper and lower sides of the second compression clamp to ensure the stability of the pre-fixation of the second compression clamp. The second clamping portions 251 are directly clamped to the edge of the second compression clamp, eliminating the need for corresponding clamping portions on the second compression clamp, thereby facilitating the installation of the second compression clamp.

[0127] The upper and lower extension directions of the second mounting seat 25 are along the axial direction of the flexible connection assembly 1. The first mounting opening 22 is typically installed at the lower end of the housing 2, and the flexible connection assembly 1 extends upward from the housing 2. Therefore, the upper and lower extension directions of the second mounting seat 25 are along the vertical direction of the air conditioner indoor unit 1000. In other embodiments, the second compression clamp and the second mounting seat 25 may be secured solely by the second fastener, or secured solely by clamping or bonding.

[0128] Please refer to Figures 1 to 5 again. In the embodiment of the present application, the flexible connection component 1 also includes a power-carrying wire 15, and the housing 2 is further provided with a second mounting port 27. The second mounting port 27 is arranged between the first fixing position 21 and the second fixing position 23, and the power-carrying wire 15 passes through the second mounting port 27 and is passed through the sleeve 14, and the power-carrying wire 15, the refrigerant pipe 11 and the drain pipe 12 are jointly fixed at the first fixing position 21.

[0129] Specifically, the flexible connection assembly 1 often also includes a power conductor 15, and the refrigerant pipe 11, the drain pipe 12 and the power conductor 15 are all installed in the sleeve 14, so as to facilitate the installation of the air-conditioning indoor unit 1000 and the air-conditioning outdoor unit. However, when in the second fixed position 23, the second fixed position 23 is only provided with a first fixed groove 41 and a second fixed groove 42, and the channel conductor and the drain pipe 12 are fixed together in the second fixed groove 42. At this time, the power conductor 15 may squeeze the drain pipe 12, affecting the drainage. The flow of the pipe 12 is controlled, so in order to reduce the possibility of the drain pipe 12 being squeezed, the casing 2 is further provided with a second mounting port 27, and the second mounting port 27 is arranged between the first fixing position 21 and the second fixing position 23. The power conductor passes through the second mounting port 27 and then passes through the sleeve 14, thereby avoiding the power conductor 15 being fixed at the second fixing position 23, and the power conductor 15 is fixed together with the refrigerant pipe 11, the drain pipe 12 and the sleeve 14 at the second fixing position 23, thereby improving the structural integrity of the flexible connection component 1.

[0130] To facilitate the passage of the power conductor 15 through the second mounting opening 27, in the embodiment of the present application, the second mounting opening 27 is connected to the first mounting opening 22, and an inwardly protruding wire-collecting portion 271 is provided on the side of the second mounting opening 27 facing the first mounting opening 22. The wire-collecting portion 271 is used to limit the position of the power conductor 15. Specifically, because the first mounting opening 22 is used for the passage of the water supply and drainage pipe 12 and the refrigerant pipe 11, while the second mounting opening 27 is only used for the passage of the power conductor 15, the area of ​​the first mounting opening 22 is necessarily larger than that of the second mounting opening 27, resulting in a smaller area of ​​the second mounting opening 27 and greater difficulty in passing the power conductor 15 through it. Therefore, the second mounting opening 27 is connected to the first mounting opening 22, so that the power conductor 15 can first pass through the first mounting opening 22 and then be fixed to the second mounting opening 27, thereby facilitating the passage of the power conductor 15 through the second mounting opening 27. To reduce the possibility of the power conductor 15 slipping out of the second mounting opening 27, an inwardly protruding wire-collecting portion 271 is provided on the side of the second mounting opening 27 facing the first mounting opening 22, thereby retaining the power conductor 15. Furthermore, the second mounting opening 27 is configured as a mounting notch provided in the first mounting opening 22 and extending toward the first fixing position 21, thereby facilitating the processing of the first mounting opening 22 and the second mounting opening 27.

[0131] In one embodiment of the present application, the air conditioner includes an indoor unit and an outdoor unit, and a refrigerant pipe 11 respectively connecting the indoor unit and the outdoor unit. Please refer to Figure 7. The refrigerant pipe 11 is pre-positioned on the fixed panel 2000 through a fixing member 300 and is fixed by a locking structure 400.

[0132] In one embodiment, the fixed panel 2000 is arranged on the indoor unit of the air conditioner and can serve as the outer panel or internal partition panel of the indoor unit of the air conditioner; in one embodiment, the fixed panel 2000 is arranged on the outdoor unit of the air conditioner; in other embodiments, both the indoor unit and the outdoor unit of the air conditioner can be provided with the fixed panel 2000.

[0133] Specifically, a first positioning portion 210 and a second positioning portion 220 are spaced apart on the plate surface 201 of the fixed panel 2000, and the refrigerant pipe 11 is placed between the first positioning portion 210 and the second positioning portion 220; the fixing member 300 is provided with a limiting portion 301 for limiting the refrigerant pipe and a first fixing portion 302 and a second fixing portion 303 for pre-positioning with the first positioning portion 210 and the second positioning portion 220 respectively; the fixing member 300 is fixedly connected to the fixed panel 2000 through a locking structure 400.

[0134] Refrigerant pipe 200 plays a key role in the refrigeration system. Its primary function is to connect the indoor and outdoor air conditioner units, transporting and recovering refrigerant. Refrigerant pipe 200 is typically made of highly elastic rubber or polyurethane, giving the hose excellent pressure and corrosion resistance. Refrigerant pipe 200 is typically curved, allowing it to flexibly adapt to various installation environments and space constraints. The hose is typically connected using quick connectors. During the cooling process, refrigerant pipe 200 is responsible for transporting refrigerant from the outdoor unit to the indoor unit, ensuring the proper operation of the refrigeration system. If necessary, refrigerant pipe 200 can also be used to recover refrigerant from the indoor unit, enabling refrigerant recycling. Refrigerant changes volume during heating and cooling, and flexible pipes can alleviate this stress, preventing loosening or breakage. Refrigerant pipe 200 is better suited to the complex environments found in buildings, equipment, and other industrial settings, such as confined spaces, various angles, and detailed components.

[0135] The technical solution of the present application realizes pre-positioning by adopting the setting of the fixing member 300 and the fixing panel 2000. When fixing the refrigerant tube 11, the refrigerant tube 11 can be pre-positioned on the fixing panel 2000 by means of the first positioning portion 210 and the first fixing portion 302 and the second positioning portion 220 and the second fixing portion 303. The movement of the refrigerant tube 11 is restricted by the limiting portion 301. There is no need to continuously press and fix the refrigerant tube 11, freeing both hands. The fixing member 300 is then locked to the fixing panel 2000 by the locking structure 400 to fix the refrigerant tube 11. In this way, the fast fixed installation of the connecting hose is realized, which can be operated by a single person, is simple to assemble, improves the production efficiency of the product, and meets the requirements of mass production.

[0136] In order to ensure that the refrigerant pipe 11 is safely and firmly arranged between the indoor unit and the outdoor unit of the air conditioner, and to prevent the refrigerant pipe 11 from being displaced or damaged due to vibration or other external forces during operation.

[0137] 8 to 10 , the fixing member 300 includes a main body section 310 and a first folding section 320 and a second folding section 330 arranged on both sides of the main body section 310. Referring to FIG8 , the limiting portion 301 is a snap-fit ​​groove 311 formed by a depression along a side of the main body section 310 away from the refrigerant tube 11, and at least a portion of the outer wall of the refrigerant tube 11 is snapped into the snap-fit ​​groove 311; the first fixing portion 302 is arranged on the first folding section 320, and the second fixing portion 303 is arranged on the second folding section 330.

[0138] During use, the fixing member 300 is clamped onto the refrigerant tube 11 through the clamping groove 311, and the fixing member 300 is moved to a suitable position so that the first fixing portion 302 of the first folding section 320 is aligned with the first positioning portion 210, and the second fixing portion 303 and the second positioning portion 220, so as to facilitate the assembly of the first fixing portion 302 and the first positioning portion 210, and the second fixing portion 303 and the second positioning portion 220. The fixing member 300 is pre-positioned on the fixed panel 2000, thereby limiting the movement of the refrigerant tube 11. This can ensure that the refrigerant tube 11 is stably fixed on the fixed panel 2000 and will not shift due to vibration or other external forces, facilitating the subsequent locking operation of the fixing member 300. The fixing member 300 adopts the configuration of the main section 310 and the two folding sections, which has a simple structure, uses less material, thereby reducing costs, optimizing space utilization, and is easy to install.

[0139] 9 and 10 , in this embodiment, in order to simplify the installation process, improve the stability and fixing effect of the fixing member 300 , and facilitate maintenance and adaptability to different installation environments, the first folding edge section 320 is a first fixing portion 302 as a whole, and the first fixing portion 302 and the first positioning portion 210 are snap-fitted together.

[0140] Specifically, the first positioning portion 210 is configured as a positioning protrusion 211 protruding from the plate surface 201 of the fixed panel 2000 , and a limiting groove 212 is formed between the positioning protrusion 211 and the plate surface 201 of the fixed panel 2000 ; the first folding section 320 is engaged with the limiting groove 212 .

[0141] Using the first folding edge section 320 as a whole as the first fixing portion 302 simplifies the structure of the fixing member 300, reduces the number of components, and can reduce production and manufacturing costs. The snap-fit ​​method usually does not require the use of additional tools. During installation, it is only necessary to insert the first folding edge section 320 into the limiting groove 212 to complete the fixation, thereby improving installation efficiency. The limiting groove 212 formed between the positioning protrusion 211 and the fixed panel 2000 can limit the movement of the fixing member 300 on the panel, improve the stability of the fixing member 300, and prevent the fixing member 300 from shifting due to vibration and other reasons. In addition, this design allows the fixing member 300 to adapt to fixed panels 2000 of different thicknesses. It only needs to adjust the height of the positioning protrusion 211 or the depth of the limiting groove 212, thereby improving the flexibility of the design.

[0142] In other embodiments, the first fixing portion 302 is configured as a raised or protruding buckle structure located on the first folded edge section 320. The first positioning portion 210 is configured as a corresponding groove or hole structure located on the fixed panel 2000 for receiving the buckle of the first fixing portion 302. The reverse configuration is also possible.

[0143] Referring to Figure 8 , the locking structure 400 includes a first locking hole 410 provided on the first hem section 320 and a first mounting hole 420 provided on the fixed panel 2000 and corresponding to the first locking hole 410. The first hem section 320 is affixed to the fixed panel 2000 by the fastener 500. Screws are screwed into the first mounting hole 420 and the first locking hole 410, and the screws pass through the fixed panel 2000, thereby firmly fixing the fixing member 300 to the fixed panel 2000.

[0144] In this embodiment, in order to simplify the installation process, improve the stability and fixing effect of the fixing member 300, and facilitate maintenance and adapt to different installation environments, the second folding section 330 is a whole second fixing portion 303, and the second folding section 330 and the second positioning portion 220 are snap-fitted.

[0145] Specifically, the second positioning portion 220 is configured as a positioning plate 2210 extending along the plate surface 201 away from the fixed panel 2000 and an elastic buckle 221 formed on the positioning plate 2210 ; the second folding section 330 is engaged with the elastic buckle 221 .

[0146] 8 to 10 , the second folded edge section 330 is used as the second fixing portion 303 , simplifying the structure of the fixing member 300 and reducing the number of components, thereby lowering production and manufacturing costs. The snap-fit ​​method generally does not require the use of additional tools. During installation, the first folded edge section 320 is first inserted into the retaining groove 212 to complete the pre-positioning of one side. The second folded edge section 330 is then pressed so that the elastic buckle 221 retains the second folded edge section 330, completing the pre-positioning process.

[0147] The design of the elastic clip 221 generally makes the installation process simpler and faster, requiring no tools. Simply insert the second hem section 330 into the elastic clip 221 and secure it using its elasticity. The elastic clip 221 provides a certain degree of elastic deformation, allowing the second hem section 330 to more easily adapt to the shape and size of the second positioning portion 220 during engagement, maintaining a good fit even with slight dimensional deviations or deformation.

[0148] 8 , the elastic buckle 221 is formed by partially bending the positioning plate 2210 , and a hollow groove 222 is formed on the positioning plate 2210 . When the elastic buckle 221 is squeezed, the hollow groove 222 can also play a role of giving way, facilitating the elastic buckle 221 to reset and engage the second folded edge section 330 .

[0149] Specifically, a positioning plate 2210 is provided on the upper and lower sides of the second folding section 330, and the elastic clips 221 on the two positioning plates 2210 are both clamped to the second folding section 330; in other embodiments, the positioning plate 2210 can be set on one side of the short side of the second folding section 330, at least extending from the middle of the short side to both sides for more than half the length of the short side.

[0150] In other embodiments, the second fixing portion 303 is also configured as a protruding or protruding buckle structure located on the second folding edge section 330. The second positioning portion 220 is configured as a corresponding groove or hole structure located on the fixed panel 2000 for receiving the buckle of the second fixing portion 303.

[0151] On this basis, the locking structure 400 includes a second locking hole 430 provided on the second folded edge section 330 and a second mounting hole 440 provided on the fixed panel 2000 and corresponding to the second locking hole 430. The second folded edge section 330 is affixed to the fixed panel 2000 under the action of the fastener 500. The second folded edge section 330 is affixed to the fixed panel 2000 under the action of the fastener 500. By screwing screws into the second mounting hole 440 and the second locking hole 430, the screws pass through the fixed panel 2000, thereby firmly fixing the fixing member 300 to the fixed panel 2000.

[0152] The first locking hole 410 and the first mounting hole 420, and the second locking hole 430 and the second mounting hole 440 can be locked to only one of them, or both of them can be locked. It can be understood that due to the pre-positioning effect of the fixing member 300 and the positioning portion of the fixing panel 2000, the installer can operate with both hands to perform the fixing operation.

[0153] In addition, referring to Figures 9 and 10, in this embodiment, in order to avoid installation errors and greatly improve assembly efficiency, the fixing part 300 and the refrigerant pipe 11 are treated with anti-mock treatment. The structures of the fixing part 300 and the refrigerant pipe 11 are symmetrically arranged. The installer does not need to judge the direction of the parts when fixing. In this way, anti-mock is effectively achieved, incorrect installation is avoided, and the difficulty of installation is reduced.

[0154] Specifically, the first folding section 320 and the second folding section 330 are symmetrical with respect to the main section 310. The first folding section 320 and the second folding section 330 have the same structure and do not need to be distinguished during installation. The first folding section 320 can be inserted into the snap-fit ​​groove 311, and the second folding section 330 can be snap-fitted with the snap. Alternatively, the second folding section 330 can be inserted into the snap-fit ​​groove 311, and the first folding section 320 can be snap-fitted with the snap.

[0155] 8 and 10 , specifically, the refrigerant pipe 11 has a first pipe opening 101 and a second pipe opening 102 on a cross section perpendicular to the extended centerline. The first pipe opening 101 and the second pipe opening 102 are important interfaces of the refrigerant pipe 11 , which are used to connect different components in the air-conditioning system to ensure that the refrigerant circulates in the system, thereby achieving the function of cooling or heating.

[0156] In this embodiment, the first pipe opening 101 and the second pipe opening 102 are symmetrical about the extension center line, and the cross-sections of the pipes (not shown) inside the first pipe opening 101 and the second pipe opening 102 can be different to adapt to different flow requirements.

[0157] The cross-section of the refrigerant tube is elliptical and symmetrical about the extended center line. In this way, when the fixing member 300 is clamped on the outer wall of the refrigerant tube, that is, the outer wall of the refrigerant tube 11 is adapted to the shape of the clamping groove 311 of the limiting portion 301, there is no need to distinguish between up and down / front and back when clamping, which can reduce the difficulty of installation.

[0158] Furthermore, the refrigerant medium is preset in the refrigerant tube 11. The air conditioner of the present application can be a split-type air conditioner that is easy for users to install personally. It uses a flexible refrigerant tube to connect the indoor heat exchanger of the air conditioner indoor unit and the outdoor heat exchanger of the air conditioner outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the air conditioner indoor unit and the air conditioner outdoor unit separately. The fixing part 300 and the refrigerant tube 11 are fool-proof designs, and the refrigerant tube 11 is pre-filled with refrigerant. Even if the installer does not have the corresponding basic knowledge, it will not be affected. This breaks the traditional requirement for specialized technicians to come to the site for installation and perform professional operations such as vacuuming, thereby reducing the difficulty of installation and enabling personal installation by the user.

[0159] In one embodiment, the indoor and outdoor air conditioner units can be integrated into a single unit. In this case, the air conditioner is a mobile air conditioner, eliminating the need for an external exhaust duct or outdoor unit. All components are integrated into a single unit. The indoor and outdoor air conditioner units are connected via a flexible refrigerant pipe. Furthermore, the air conditioner compressor can be located within the indoor unit. However, this design is not limited to this. In other embodiments, the air conditioner of this application can also be a conventional split-type air conditioner.

[0160] This makes the air conditioner easy for users to install. It uses flexible refrigerant piping to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. Refrigerant is already injected into the refrigerant circuit before the unit leaves the factory. This means that when users install the unit themselves, they only need to secure the indoor and outdoor units separately, eliminating the need to assemble refrigerant piping or inject refrigerant. This reduces installation complexity and makes it easy for users to install the unit themselves.

[0161] Placing the compressor in the indoor air conditioner reduces the weight of the outdoor unit, making it easier for users to find a suitable installation location and moving the outdoor unit themselves. This reduces installation effort and labor costs, especially in areas with high labor costs. To reduce noise, the indoor unit's compressor can also be treated with noise-reducing materials or equipped with a buffer structure to reduce the transmission of compressor vibration.

[0162] Thus, this application provides an air conditioner that is simpler, more efficient, and suitable for DIY installation. When fixing the refrigerant pipe, a fixing piece is snapped onto the outer wall of the refrigerant pipe. Then one side of the fixing piece is inserted into the slot, and the other side is snapped into place with an elastic buckle. This reduces the operator's skill requirements and improves installation efficiency and safety. This greatly simplifies the installation process, allowing users to easily complete the fixing operation without relying on professional personnel.

[0163] In one embodiment of the present application, as shown in Figures 11 to 19, the air conditioner 100 includes an outdoor unit, a refrigerant pipe 200 and an indoor unit 3000, one end of the refrigerant pipe 200 is connected to the outdoor unit; it includes an inner case 3100 and an installation component 4000, the outer surface of the inner case 3100 is provided with a mounting position 311, the connecting pipe 320 of the indoor unit 3000 extends to the mounting position 311, the other end of the refrigerant pipe 200 is connected to the connecting pipe 320, and the installation component 4000 is fixed to the inner case 3100 to fix the refrigerant pipe 200 and the connecting pipe 320 to the inner case 3100.

[0164] For reference, in the traditional solution, the outdoor unit and the indoor unit 3000 are connected by a dedicated copper pipe. First, when the air conditioner is working, the compressor in the outdoor unit compresses the refrigerant, changing the gaseous refrigerant into liquid and releasing heat. At the same time, the liquid refrigerant enters the condenser (radiator) of the outdoor unit, and the fan discharges the heat generated during compression to the outdoor space, turning the refrigerant into a liquid with a lower temperature. It passes through the copper pipe (high-pressure pipe or liquid pipe) and enters the evaporator of the indoor unit 3000. Because the pressure of the refrigerant decreases after entering the evaporator, the refrigerant vaporizes rapidly and absorbs a large amount of heat around the evaporator. The fan in the indoor unit 3000 can blow "cold air" into the indoor space, achieving a cooling effect. Then the vaporized refrigerant comes out of the evaporator of the indoor unit 3000, and the refrigerant passes through another relatively thick copper pipe (low-pressure pipe or gas pipe) connecting the indoor unit 3000 and the indoor and outdoor units, and enters the compressor of the outdoor unit again. The refrigerant pipe 200 here replaces the copper pipe between the indoor unit 3000 and the outdoor unit. The refrigerant pipe 200 includes an inner pipe assembly and a protective sleeve arranged outside the inner pipe assembly. The inner pipe assembly includes the above-mentioned gas pipe and liquid pipe, that is, two refrigerant pipes. The inner pipe assembly can also include water pipes, lines, etc. The protective sleeve is arranged on the outside of the inner pipe assembly to play a protective role and also ensure that the inner pipe assembly is arranged in an orderly and neat manner.

[0165] The technical solution of the present application connects the indoor unit 3000 and the outdoor unit by using a refrigerant pipe 200, replacing the traditional solution in which a dedicated copper pipe is used to connect the indoor unit 3000 and the outdoor unit. Due to the flexibility of the refrigerant pipe 200, the indoor unit 3000 and the outdoor unit can be pre-filled with refrigerant before leaving the factory, completing the refrigerant circulation loop of the indoor unit 3000 and the outdoor unit. This makes it easier for users to install them themselves later, and the installation of the air conditioner 100 is more convenient. In addition, the refrigerant pipe 200 extends to the inner chassis 3100 of the indoor unit 3000 and is connected to the interface of the evaporator of the indoor unit 3000. The refrigerant pipe 200 is fixed by the installation component 4000 to ensure the stability of the refrigerant pipe 200, prevent it from shaking, avoid loosening, etc., and improve the quality of the product.

[0166] In one embodiment, the mounting assembly 4000 may be a cable tie, a metal buckle, or the like.

[0167] 11 , in this embodiment, in order to facilitate fixation and ensure a good fixation effect, a pre-positioning structure 5000 and a fixing structure 600 are provided between the mounting assembly 4000 and the inner chassis 3100. The pre-positioning structure 5000 is used to pre-fix the mounting assembly 4000 on the inner chassis 3100, and the fixing structure 600 is used to fix the mounting assembly 4000 to the inner chassis 3100.

[0168] In one embodiment, the mounting assembly 4000 includes a first mounting member 4100 and a second mounting member 4200 , wherein the first mounting member 4100 and the second mounting member 4200 are spaced apart at the mounting position 311 , the first mounting member 4100 is disposed at the connecting pipe 320 , and the second mounting member 4200 is disposed at the refrigerant pipe 200 .

[0169] In another embodiment, the mounting assembly 4000 may be a unitary member formed by the first mounting member 4100 and the second mounting member 4200.

[0170] The mounting component 4000 is generally made of metal or hard plastic. By arranging a pre-positioning structure 5000 on the mounting component 4000, during the installation of the air-conditioning outdoor unit, the mounting component 4000, such as the first mounting component 4100 and the second mounting component 4200, can be pre-fixed on the inner chassis 3100. This facilitates the subsequent screw locking process within a limited space. Compared to the need to apply external force to fix and correspond to the screw locking holes during installation, installation is more convenient after being pre-fixed by the pre-positioning structure 5000.

[0171] The first fixing member and the second fixing member are spaced apart along the connection direction of the refrigerant pipe 200, so that a better fixing effect can be achieved with fewer parts. Compared with the overall method, the parts are smaller in size, the mold making cost is lower, and the installation is more convenient.

[0172] Specifically, the refrigerant pipe 200 includes an inner pipe assembly and a protective sleeve that is mounted on the inner pipe assembly. The inner pipe assembly is partially exposed from the protective sleeve and connected to the piping of the indoor unit 3000. A first mounting member 4100 is located on the piping of the indoor unit 3000, and a second mounting member 4200 is located on the protective sleeve. The first mounting member 4100 is secured to the inlet and outlet copper pipes (liquid pipe / gas pipe) of the indoor unit 3000, near the connection of the refrigerant pipe 200. This ensures the copper pipe portion of the indoor unit 3000 is stable and prevents shaking. The second mounting member 4200 is secured to the protective sleeve, ensuring the stability of the refrigerant pipe 200 within the inner housing 3100. This ensures that both the refrigerant pipe 200 and the inlet and outlet copper pipes of the indoor unit 3000 are securely fixed to the inner housing 3100, preventing the connection from becoming loose during subsequent movement of the indoor unit 3000, thereby ensuring product quality.

[0173] Specifically, the pre-positioning structure 5000 includes a first pre-positioning structure 510 , which is disposed on both sides of the first mounting member 4100 . The fixing structure 600 includes a first fixing structure 610 , which is disposed on both sides of the first mounting member 4100 .

[0174] In one embodiment, the first mounting member 4100 includes a fixed section 411 located on the outside of the connecting tube 320, and two extension sections 412 located at both ends of the fixed section 411. Two limiting slots 313 are provided at the mounting position 311, and one of the extension sections 412 is placed in one of the limiting slots 313. The limiting slot (313) and the extension section (412) cooperate to form the first pre-positioning structure (510). The first fixing structure 610 is configured as a first screw hole 611 provided on the extension section 412 and the inner chassis 3100.

[0175] Referring to Figures 15 and 16 , in a specific embodiment, a limit slot 313 is provided above the mounting position 311 of the inner chassis 3100. During installation, the two extensions 412 of the first mounting member 4100 are placed into the limit slot 313, with the notch of the limit slot 313 facing upward, like a "slide." The two extensions 412 correspond to the notches of the limit slot 313, like "sliders," and the "sliders" are inserted into the "slide." The first fixing structure 610 is configured as a first screw hole 611 provided on the extensions 412 and the inner chassis 3100. At this point, tightening the screws secures the first mounting member 4100 to the inner chassis 3100. Compared to directly fastening with screws, securing the first mounting member 4100 is more convenient. The first mounting member 4100 includes a fixed section 411 located on the outside of the connecting tube 320, and two extension sections 412 located at both ends of the fixed section 411. Two limiting slots 313 are provided at the mounting position 311. One of the extension sections 412 is placed in one of the limiting slots 313. The limiting slot 313 and the extension section 412 cooperate to form the first pre-positioning structure 510. The first fixing structure 610 is configured as a first screw hole 611 provided on the extension section 412 and the inner chassis 3100.

[0176] In another embodiment, the limiting portion and the connecting portion may be pre-fixed by means of buckles and buckle grooves.

[0177] 11 , in order to protect the connecting pipe 320 of the indoor unit 3000 and avoid the problem of leakage caused by a head-on collision between the first mounting member 4100 and the connecting pipe 320 , the indoor unit 3000 further includes a protective member 4300 , which is sleeved on the connecting pipe 320 and located between the first mounting member 4100 and the inner chassis 3100 .

[0178] In one embodiment, the protective member 4300 is made of rubber material, and a mounting groove corresponding to the shape of the connecting tube 320 is opened on the protective member 4300. The connecting tube 320 is inserted into the mounting groove, which can not only provide protection but also limit the movement of the connecting tube 320. On the basis of the first mounting member 4100, the fixing effect is better.

[0179] In another embodiment, the protective member 4300 is made of foam, silicone, etc., and a mounting groove can also be provided.

[0180] Specifically, the first mounting member 4100 restricts the protective member 4300. To ensure the strength of the first mounting member 4100 and the effective fixation of the protective member 4300 to the inner chassis 3100, a reinforcing rib 413 is provided on the side of the fixing section 411 facing the refrigerant pipe 200. The specific arrangement of the reinforcing rib 413 is not limited and can be designed according to actual needs.

[0181] Referring to Figures 13 and 14, regarding the second mounting member 4200, in one embodiment, the pre-positioning structure 5000 includes a second pre-positioning structure 520, and the fixing structure 600 includes a second fixing structure 620. The second mounting member 4200 includes a limiting section 421 located on the outside of the refrigerant tube 200, and two folding sections 422 located on both sides of the limiting section 421. Two limiting hooks 312 are also provided on the inner chassis 3100, and the two folding sections 422 are respectively placed on the hook mouths of the two limiting hooks 312. The folding sections 422 and the limiting hooks 312 constitute the second pre-positioning structure 520, and the second fixing structure 620 is configured as a second screw hole 621 provided on the folding section 422 and the inner chassis 3100. The two limiting hooks 312 are generally "clothes hooks", and the two folding sections 422 are hung on the limiting hooks 312 to achieve fixation. At this time, the folding section 422 fits or is close to the inner chassis 3100, and the folding section 422 and the second screw hole 621 of the inner chassis 3100 are relative to each other. The locking screws can achieve the fixation of the second mounting component 4200 and the inner chassis 3100. Moreover, the second mounting component 4200 adopts a screw locking structure set on the two folding sections 422 to ensure the fixing effect of the refrigerant pipe 200. The movement of the refrigerant pipe 200 outside the indoor unit 3000 will not affect the fixed part on the inner chassis 3100, thereby ensuring the quality of the product.

[0182] Specifically, the second mounting member 4200 restricts the refrigerant tube 200. To ensure the strength of the second mounting member 4200 and the securement of the refrigerant tube 200 to the inner chassis 3100, a reinforcing rib 413 is provided on the side of the limiting section 421 facing the refrigerant tube 200. The specific arrangement of the reinforcing rib 413 is not limited and can be designed according to actual needs.

[0183] 17 to 19 , to protect the refrigerant pipe 200 and the connecting pipe 320, the indoor unit 3000 further includes a protective housing 700. The protective housing 700 is positioned at the mounting position 311 and secured to the inner chassis 3100. The mounting assembly 4000 is located within the protective housing 700. The inner chassis 3100 is recessed inward to form the mounting position 311, which accommodates the protective housing. This allows the protective housing to be installed discreetly on the inner chassis 3100, ensuring both protection and aesthetic appeal.

[0184] In one embodiment, the protective shell is fixed to the inner chassis 3100 by screwing, which is simple to install and low in cost.

[0185] The assembly is difficult if only screws are used for fixing. In this embodiment, the inner chassis 3100 is provided with a plug-in protrusion 314 , and the bottom of the protective shell 700 is provided with a matching plug-in groove 720 .

[0186] During installation, the plug-in groove 720 at the bottom of the protective shell is aligned with the plug-in protrusion 314 of the inner chassis 3100. The plug-in groove 720 at the bottom of the protective shell can extend along the width of the protective shell, or two can be set in the width direction. In this way, the protective shell can be matched with the plug-in protrusion 314 and the plug-in groove 720, and the top of the protective shell can be pushed close to the inner chassis 3100 to conveniently perform the screw tightening operation, making installation more convenient.

[0187] In this solution, a mounting lug 710 is provided on the top of the protective shell 700, and the mounting lug 710 is provided with a mounting hole 711. The inner chassis 3100 is provided with a fixing hole 315 corresponding to the mounting hole 711. Fasteners pass through the mounting hole 711 and the fixing hole 315 to fix the protective shell 700 to the inner chassis 3100.

[0188] In other solutions, the fixing holes 315 of the protective shell 700 may also be provided on the side of the protective shell 700 .

[0189] It should be noted that the top of the protective shell 700 is hollow, so that the refrigerant pipe 200 can come out of the protective shell 700 and extend to the outdoor unit.

[0190] In order to ensure the strength of the protective shell 700 , a reinforcement structure 730 is further provided in the protective shell 700 . The reinforcement structure 730 is provided at the bottom of the protective shell 700 .

[0191] In one embodiment, the reinforcement structure 730 is configured as a reinforcement rib 413 .

[0192] In other embodiments, the reinforcement structure 730 may also be a connecting rod provided on two side walls of the protective shell 700 .

[0193] 20 , the connection between the refrigerant pipe 200 and the outdoor unit 800 will be described.

[0194] Currently, in the air conditioner 100, the indoor unit 3000 and the outdoor unit 800 are assembled separately; during installation, it is necessary to first install the indoor unit 3000 and the outdoor unit 800 separately, then connect the pipeline between the indoor unit 3000 and the outdoor unit 800, and finally perform the exhaust and refrigerant filling operations to ensure the normal operation of the air conditioner 100.

[0195] However, the connection of air conditioning pipelines and the filling of refrigerant require professional personnel, which is inconvenient to install and has high labor costs. In the traditional solution, the refrigerant circuit between the indoor unit 3000 and the outdoor unit 800 needs to be connected through a dedicated copper pipe. The copper pipe is a hard pipe that is easily broken under stress. As a result, the indoor unit 3000 and the outdoor unit 800 cannot be pre-connected before leaving the factory to solve the problem of subsequent connection of pipelines and filling of refrigerant. The refrigerant pipe is used to replace the copper pipe in the traditional solution. The flexibility of the refrigerant pipe allows the indoor and outdoor units to be connected together, so that the process of connecting the indoor and outdoor units and filling the refrigerant can be completed in advance before leaving the factory. In this way, after purchase, the user only needs to install the indoor unit 3000 and the outdoor unit 800 and can use it, which is convenient for the user to install it by themselves.

[0196] After the indoor unit 3000 and the outdoor unit 800 are pre-connected through the refrigerant pipe and the refrigerant is pre-filled in the refrigerant pipe, the indoor unit and the outdoor unit circuit, it is necessary to ensure the stability of the connection between the refrigerant pipe and the indoor unit to avoid shaking. Because the compressor part of the outdoor unit 800 and the evaporator part of the indoor unit 3000 are still copper pipe interfaces, it is necessary to ensure the stability of the refrigerant pipe after connection with the indoor unit 3000 and the outdoor unit 800. It is also necessary to consider the convenience of installation, reduce the cost of parts processing, and shorten the assembly process.

[0197] Specifically, the outdoor unit 800 includes an outer housing 810, a partition plate 820, and a fixing assembly 830. The partition plate 820 is disposed within the outer housing 810. The other end of the refrigerant pipe 200 extends to the surface of the partition plate 820 and is connected to the piping of the outdoor unit 800. Specifically, the other end of the refrigerant pipe 200 is connected to the connecting pipe 320 shown in FIG. 20 . The fixing assembly 830 is used to secure the other end of the refrigerant pipe 200 to the partition plate 820. The mounting structure and installation method of the fixing assembly 830 can be referenced to the pre-positioning structure 5000 and fixing structure 600 of the mounting assembly 4000 in the indoor unit 3000, and will not be further described here.

[0198] In summary, the air conditioner 100 of the present application can be a split-type air conditioner 100 that is easy for users to install individually. It uses a flexible refrigerant pipe to connect the indoor heat exchanger of the air conditioner's indoor unit 3000 and the outdoor heat exchanger of the air conditioner's outdoor unit, and refrigerant is injected into the refrigerant circuit before the device leaves the factory. In this way, when the user installs the device themselves, they only need to fix the air conditioner indoor unit 3000 and the air conditioner outdoor unit separately, without having to assemble the refrigerant pipe and add refrigerant, thereby reducing the difficulty of installation and enabling user-installation. However, the present design is not limited to this. In other embodiments, the air conditioner 100 of the present application can also be an ordinary split-type air conditioner 100.

[0199] The above are merely exemplary embodiments of the present application and are not intended to limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the technical concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
