[0031] Currently, in air conditioners, the indoor unit and outdoor unit are assembled separately. During installation, the indoor unit and outdoor unit need to be installed separately first, and then the pipelines between the indoor unit and the outdoor unit need to be connected. Finally, the air is exhausted and the refrigerant is charged to ensure the normal operation of the air conditioner.

[0032] However, the connection of air conditioning pipelines and the filling of refrigerant require professional operation, which is inconvenient to install and has high labor costs. In the traditional solution, the refrigerant circuit between the indoor and outdoor units 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 and outdoor units cannot be pre-connected before leaving the factory to solve the problem of subsequent connection of pipelines and filling of refrigerant. The refrigerant hose is used to replace the copper pipe in the traditional solution. The flexibility of the refrigerant hose 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, users only need to install the indoor and outdoor units after purchase, which is convenient for users to install themselves.

[0033] After pre-connecting the indoor unit and the outdoor unit through the refrigerant hose and pre-filling the refrigerant in the refrigerant hose, indoor unit and outdoor unit circuits, it is necessary to ensure the stability of the connection between the refrigerant hose and the indoor unit to avoid shaking. Because the compressor part of the outdoor unit and the evaporator part of the indoor unit are still copper pipe interfaces, it is necessary to ensure the stability of the refrigerant hose after connection with the indoor unit and the outdoor unit. It is also necessary to consider the convenience of installation, reduce the cost of parts processing, and shorten the assembly process.

[0034] To this end, the present invention proposes an air conditioner, which aims to ensure the stability of the refrigerant hose after being connected to the outdoor unit, thereby ensuring the quality of the product.

[0035] In one embodiment of the present invention, Figures 1 to 8As shown, the air conditioner 100 includes an indoor unit 600, a refrigerant hose 200 and an outdoor unit 300, one end of the refrigerant hose 200 is connected to the indoor unit 600; it includes an outer case 310, a partition plate 330 and a fixing assembly 340, the partition plate 330 is arranged in the outer case 310, the other end of the refrigerant hose 200 extends to the plate surface 331 of the partition plate 330, and is connected to the pipeline 320 of the outdoor unit 300, and the fixing assembly 340 is used to fix the other end of the refrigerant hose 200 on the partition plate 330.

[0036] For reference, in the traditional solution, the outdoor unit 300 and the indoor unit 600 are connected by a dedicated copper pipe. First, when the air conditioner is working, the compressor in the outdoor unit 300 compresses the refrigerant, turning the gaseous refrigerant into liquid and releasing heat. At the same time, the liquid refrigerant enters the condenser (radiator) of the outdoor unit 300. The fan discharges the heat generated during compression to the outdoor space, turning the refrigerant into a liquid with a lower temperature. The refrigerant passes through the copper pipe (high-pressure pipe or liquid pipe) and enters the evaporator of the indoor unit 600. Because the pressure of the refrigerant decreases after entering the evaporator, the refrigerant quickly vaporizes and absorbs a large amount of heat around the evaporator. The fan in the indoor unit 600 can blow "cold air" into the indoor space, achieving a cooling effect. The vaporized refrigerant then comes out of the evaporator of the indoor unit 600, passes through another relatively thick copper pipe (low-pressure pipe or gas pipe) connecting the indoor unit 600 and the outdoor unit 300, and enters the compressor of the outdoor unit 300 again. The refrigerant hose 200 here replaces the copper pipe between the indoor unit 600 and the outdoor unit 300 mentioned above. The refrigerant hose 200 includes an inner tube assembly 210 and a protective sleeve 220 sleeved on the outside of the inner tube assembly 210. The inner tube assembly 210 includes the above-mentioned gas pipe and liquid pipe, that is, two refrigerant pipes. The inner tube assembly 210 can also include water pipes, lines, etc. The protective sleeve 220 is sleeved on the outside of the inner tube assembly 210 to play a protective role and also ensure that the inner tube assembly 210 is arranged in an orderly and neat manner.

[0037] The technical solution of the present invention connects the indoor unit 600 and the outdoor unit 300 by using a refrigerant hose 200, replacing the traditional solution in which a dedicated copper tube is used to connect the indoor unit 600 and the outdoor unit 300. Due to the flexibility of the refrigerant hose 200, the indoor unit 600 and the outdoor unit 300 can be pre-filled with refrigerant before leaving the factory, completing the refrigerant circulation loop of the indoor unit 600 and the outdoor unit 300. This makes it easier for users to install the air conditioner 100 later, and the installation of the air conditioner 100 is more convenient. In addition, the refrigerant hose 200 extends to the partition plate 330 of the outdoor unit 300 and is connected to the interface of the compressor. The refrigerant hose 200 is fixed by the fixing assembly 340 to ensure the stability of the refrigerant hose 200, prevent it from shaking, avoid loosening, etc., and improve the quality of the product.

[0038] In one embodiment, the fixing component 340 can be a cable tie, a metal buckle, etc.

[0039] Reference Figure 3 In this embodiment, in order to facilitate fixation and ensure good fixation effect, a pre-positioning structure 400 and a screw locking structure 500 are provided between the fixing component 340 and the partition plate 330. The pre-positioning structure 400 is used to pre-fix the fixing component 340 on the partition plate 330, and the screw locking structure 500 is used to connect and fix the fixing component 340 to the partition plate 330.

[0040] Combined with reference Figure 4 and Figure 5 In one embodiment, the fixing assembly 340 includes a first fixing member 350 and a second fixing member 360 , and the first fixing member 350 and the second fixing member 360 are spaced apart along the extending direction of the refrigerant hose 200 .

[0041] In another embodiment, the fixing assembly 340 may be a unitary member formed by the first fixing member 350 and the second fixing member 360 .

[0042] The fixing component 340 is generally made of metal or hard plastic. By arranging a pre-positioning structure 400 on the fixing component 340, during the installation process of the air-conditioning outdoor unit 300, the fixing component 340, such as the first fixing member 350 and the second fixing member 360, can be pre-fixed on the partition plate 330. This can facilitate the subsequent screw locking process within a limited space. Compared with the need to apply external force to fix and correspond to the screw locking holes during installation, it is more convenient to install after being pre-fixed by the pre-positioning structure 400.

[0043] The first fixing member 350 and the second fixing member 360 are spaced apart along the connection direction of the refrigerant hose 200, so that fewer parts can be used to achieve a better fixing effect. Compared with the overall method, the parts are smaller in size, the mold making cost is lower, and the installation is more convenient.

[0044] Specifically, the refrigerant hose 200 includes an inner tube assembly 210 and a protective sleeve 220 mounted on the outside of the inner tube assembly 210. Part of the inner tube assembly 210 is exposed from the protective sleeve 220 and is connected to the pipeline 320 of the outdoor unit 300. The first fixing member 350 is located at the exposed part of the inner tube assembly 210, and the second fixing member 360 is located at the protective sleeve 220.

[0045] The first fixing part 350 is fixed at the connection between the inlet and outlet copper pipes (liquid pipe / gas pipe) of the outdoor unit 300 and the refrigerant hose 200, so as to ensure that the copper pipe part of the outdoor unit 300 is stable and not easy to shake; and the second fixing part 360 is fixed at the protective cover 220 to ensure the stability of the refrigerant hose 200 on the partition plate 330, so that the refrigerant hose 200 and the inlet and outlet copper pipes of the outdoor unit 300 are fixed on the partition plate 330, and the connection is not easy to detach, thereby ensuring a stable connection. In this way, it is not easy to loosen during the subsequent movement of the outdoor unit 300, thereby ensuring the quality of the product.

[0046] Specifically, the pre-positioning structure 400 includes a first pre-positioning structure 410, which is arranged on one side of the first fixing member 350, and the screw locking structure 500 includes a first locking structure 510, which is arranged on the other side of the first fixing member 350.

[0047] Combined with reference Figure 6 In one embodiment, the first fixing member 350 includes a limiting section 351 located on the outside of the inner tube assembly 210, and a connecting section 352 located on both sides of the limiting section 351. A limiting flange 332 is provided on the partition plate 330, and a limiting opening 333 is formed between the limiting flange 332 and the partition plate 330. The first pre-positioning structure 410 includes a connecting section 352 and the limiting opening 333 for inserting the connecting section 352. The first locking structure 510 is provided between the other connecting section 352 and the partition plate 330.

[0048] 333 , the first fixing member 350 is pre-fixed on the partition plate 330 . A screw hole is provided on the other opposite connecting section 352 . During installation, the first fixing member 350 only needs to be fastened to the partition plate 330 by tightening the screw, which makes the installation more convenient. The first fixing member 350 fixes the pipe 320 of the outdoor unit 300 to ensure that the pipe 320 is not easily detached from the partition plate 330 . Compared with other solutions, the matching area between the limiting opening 333 and the connecting section 352 is large, and the installation is convenient. During installation, only one end of the connecting section 352 needs to be inserted into the limiting opening 333 . Even if the compressor is closer to the chassis, the installation is also very convenient compared with other solutions.

[0049] In another embodiment, the first pre-positioning structure 410 may also be pre-fixed by means of a buckle 364 and a buckle groove 334 .

[0050] Reference Figure 5 and Figure 6 Specifically, the pre-positioning structure 400 includes a second pre-positioning structure 420, and the second pre-positioning structure 420 includes a buckle 364 provided on the second fixing member 360, and a buckle groove 334 provided on the partition plate 330, and the buckle 364 is snap-connected with the buckle groove 334.

[0051] In one embodiment, the second fixing member 360 includes a fixing section 361 located on the outside of the protective cover 220, and folded edge sections 363 located on both sides of the fixing section 361. The buckle 364 is provided on a folded edge section 363, and the buckle groove 334 passes through the partition plate 330. The screw locking structure 500 includes a second locking structure 520, and the second locking structure 520 is provided on each of the folded edge sections 363.

[0052] The buckle 364 extends on the folding edge section 363 toward the partition plate 330, that is, the buckle 364 section and the folding edge section 363 are in an intersecting relationship. The buckle 364 is a hook bent downward, and the buckle groove 334 on the partition plate 330 is like a long and narrow slit. When installing, the buckle 364 is inserted into the buckle groove 334, and the hook part of the buckle 364 abuts against the groove edge of the buckle groove 334 to achieve fixation. At this time, the folding edge section 363 is in contact with or close to the partition plate 330, and the screw locking structure 50 on the folding edge section 363 is fixed. 0 is configured as a screw hole, so that when the buckle 364 cooperates with the buckle groove 334, the screw holes of the folding section 363 and the partition plate 330 are relatively positioned, and the locking screws can achieve the fixation of the second fixing member 360 and the partition plate 330. In addition, the second fixing member 360 adopts a screw locking structure 500 set on the folding section 363 to ensure the fixing effect of the refrigerant hose 200. The movement of the refrigerant hose 200 outside the outdoor unit 300 will not affect the fixed part on the partition plate 330, thereby ensuring the quality of the product.

[0053] Furthermore, to ensure that the second fixing member 360 secures the refrigerant hose 200, corresponding regions of the fixing section 361 and the partition plate 330 are provided with abutment protrusions 362 facing each other, and the abutment protrusions 362 abut the protective sleeve 220. This allows the limiting section 351 of the second fixing member 360 to better apply a pre-tightening force to the protective sleeve 220 of the refrigerant hose 200, and the engagement of the abutment protrusions 362 also ensures that the refrigerant hose 200 is not easily dislodged. Thus, only the second fixing member 360 is required to secure the portion of the refrigerant hose 200 on the partition plate 330 securely. Furthermore, the second fixing member 360 is easy to install and has low processing costs.

[0054] Specifically, in the traditional solution, the outdoor unit 300 uses a partition plate 330 to divide the outer case 310 into chambers, one chamber is arranged with a fan and a heat exchanger, and the other chamber is arranged with a compressor and an electronic control component; in this solution, in order to ensure that the routing of the refrigerant hose 200 does not affect the subsequent installation of the outdoor unit 300, the refrigerant hose 200 is arranged at the edge of the outdoor unit 300. The outdoor unit 300 is usually rectangular, and the refrigerant hose 200 is arranged at the short edge of the rectangle, extending from the top of the outdoor unit 300 to the bottom. At this time, if the traditional solution is adopted, the routing process of the refrigerant hose 200 will be difficult to fix. Therefore, in this solution, the outdoor unit 300 also includes a side plate 370 of the heat exchanger placed in the outer case 310. One side of the partition plate 330 is connected to the outer case 310, and the other side is connected to the side plate 370 of the heat exchanger. Specifically, a plurality of ventilator pipe holes are arranged on the plate surface 331 of the side plate 370 of the ventilator for the copper tubes of the ventilator to pass through. The side plate 370 of the ventilator is close to the edge of the rectangle. The loop formed by the connection between the pipeline 320 of the outdoor unit 300 and the refrigerant hose 200 is located in the accommodating cavity between the partition plate 330 and the outer casing, and is fixed to the partition plate 330 by the fixing component 340. This does not affect the arrangement space of the fan and the compressor, and also ensures that the connection between the refrigerant hose 200 and the pipeline 320 of the outdoor unit 300 is stable and not easy to detach, thereby ensuring the quality of the product.

[0055] Reference Figure 6 In order to facilitate the connection between the partition plate 330 and the side plate 370 of the heat exchanger and to facilitate the installation of the partition plate 330, the side plate 370 of the heat exchanger is provided with a mounting lug 371. The mounting lug 371 and the partition plate 330 are both provided with screw holes for screws to pass through to lock the partition plate 330 to the side plate 370 of the heat exchanger.

[0056] In the connection scheme using screws, at least screw positions are usually required to ensure the fixing effect. The connection position between the partition plate 330 and the side plate 370 of the heat exchanger is close to the edge of the outer chassis 310, and the operating space is limited. In order to improve the convenience of installation and improve the assembly efficiency of the product, a snap-on structure is also provided between the side plate 370 of the heat exchanger and the partition plate 330.

[0057] In one embodiment, the snap-fit ​​structure includes a snap-fit ​​flange 372 provided on the side plate 370 of the heat exchanger and a snap-fit ​​notch 335 provided on the partition plate 330 . The snap-fit ​​flange 372 is spaced apart from the mounting lug 371 , and a portion of the snap-fit ​​flange 372 is exposed on the partition plate 330 .

[0058] During installation, the snap-fit ​​flange 372 of the side plate 370 of the heat exchanger passes through the snap-fit ​​notch 335 from the back side of the partition plate 330 to the front side of the partition plate 330. In this way, the snap-fit ​​structure can also play a role of pre-fixing. At this time, the screw holes on the mounting lugs 371 are aligned with the screw holes on the partition plate 330, and it is very convenient to tighten the screws to fix the side plate 370 and the partition plate 330 of the heat exchanger.

[0059] In another embodiment, the snap-fit ​​structure may be a slide groove provided on the side plate 370 of the heat exchanger and a slider provided on the edge of the partition plate 330, and the partition plate 330 is snapped into the slide groove of the heat exchange plate by sliding and plugging.

[0060] Reference Figure 7 and Figure 8 It is not difficult to imagine that in the process of the refrigerant hose 200 passing through the outer chassis 310 and entering the interior, an avoidance opening 393 needs to be opened in the outer chassis 310. The chassis is generally made of sheet metal, and the incision is relatively sharp. In order to avoid cutting the refrigerant hose 200 and protect the safety of personnel, the outdoor unit 300 also includes a protective cover 380. The outer chassis 310 includes a chassis and a top cover 390 corresponding to the chassis. The top cover 390 is provided with a avoidance opening 393. The protective cover 380 is embedded in the avoidance opening 393, and the refrigerant hose 200 is passed through the protective cover 380.

[0061] Specifically, in one embodiment, the protective cover 380 is made of rubber, which has a certain hardness and protective capability.

[0062] In other embodiments, the protective cover 380 may also be made of plastic or other materials.

[0063] In order to facilitate the installation of the protective cover 380 , in one solution, the protective cover 380 can be embedded into the avoidance opening 393 by utilizing the flexible deformation of its own material.

[0064] In this solution, the protective cover 380 is provided with a section. When the protective cover 380 is installed, the section can be staggered, thereby facilitating the protective cover 380 to be embedded in the avoidance opening 393 and facilitating the installation of the protective cover 380.

[0065] Regarding the location of the protective cover 380 , in one embodiment, the protective cover 380 is disposed on the top of the outer chassis 310 .

[0066] In another embodiment, the protective cover 380 may be provided on a side of the outer chassis 310 .

[0067] In order to solve the problem that the protective cover 380 is easily loosened when directly embedded in the avoidance opening 393, a limiting structure is provided between the protective cover 380 and the top cover 390, and the limiting structure is used to fix the protective cover 380 and the top cover 390.

[0068] In one embodiment, the limiting structure includes a first annular protrusion 394 provided at the avoidance opening 393 and a first annular groove 391 provided on the protective cover 380 , wherein the first annular protrusion 394 cooperates with the first annular groove 391 .

[0069] In order to further enhance the securing effect of the protective cover 380, the retaining structure further includes a second annular protrusion 395 provided on the avoidance opening 393, and a third annular protrusion 392 provided on the protective cover 380. A second annular groove 396 is formed between the second annular protrusion 395 and the first annular protrusion 394, and the third annular protrusion 392 is embedded in the second annular groove 396. The cross-sectional shape of the third annular protrusion 392 is similar to a "7".

[0071] Regarding the connection between the indoor unit 600 and the refrigerant hose 200.

[0072] Reference Figure 9 The indoor unit 600 includes an inner chassis 610 and a mounting assembly 620. The outer surface of the inner chassis 610 is provided with a mounting position. The connecting pipe of the indoor unit 600 extends to the mounting position. The other end of the refrigerant hose 200 is connected to the connecting pipe. The mounting assembly 620 is fixed to the inner chassis 610 to fix the refrigerant hose 200 and the connecting pipe in the inner chassis 610.

[0073] In one embodiment, the mounting assembly 620 may be a cable tie, a metal buckle, or the like.

[0074] In this embodiment, in order to facilitate fixation and ensure good fixation effect, a pre-positioning structure 400 and a screw locking structure 500 are provided between the installation component 620 and the inner chassis 610, which can be set in the same way as the outdoor unit 300. The pre-positioning structure 400 is used to pre-fix the installation component 620 on the inner chassis 610, and the screw locking structure 500 is used to fix the installation component 620 to the inner chassis 610.

[0075] In one embodiment, the mounting assembly 620 includes a first mounting member and a second mounting member, which are spaced apart at mounting positions. The first mounting member is disposed at the connecting pipe, and the second mounting member is disposed at the refrigerant hose 200 .

[0076] In another embodiment, the mounting assembly 620 may be a unitary member formed by integrating the first mounting member and the second mounting member.

[0077] The mounting assembly 620 is generally made of metal or hard plastic. By arranging a pre-positioning structure on the mounting assembly 620, during the installation of the air conditioner outdoor unit, the mounting assembly 620, such as the first mounting part and the second mounting part, can be pre-fixed on the inner chassis 610. 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, it is more convenient to install after being pre-fixed by the pre-positioning structure.

[0078] Specifically, the refrigerant hose 200 includes an inner tube assembly 210 and a protective sleeve 220 that fits over the inner tube assembly 210. Portions of the inner tube assembly 210 are exposed outside the protective sleeve 220 and connected to the indoor unit 600's piping 320. A first mounting member is located within the indoor unit 600's piping, while a second mounting member is located within the protective sleeve. The first mounting member is secured to the indoor unit 600's inlet and outlet copper pipes (liquid pipe / gas pipe) near the connection of the refrigerant hose 200, ensuring stability and preventing the copper pipes from shaking. The second mounting member is secured to the protective sleeve 220, ensuring the stability of the refrigerant hose 200 within the inner chassis. This ensures that the refrigerant hose 200 and the indoor unit 600's inlet and outlet copper pipes are both securely fixed to the inner chassis, preventing them from becoming detached and maintaining a stable connection. This prevents loosening during subsequent movement of the indoor unit 600, thus ensuring product quality.

[0079] In order to protect the connecting pipe of the indoor unit 600 and avoid the problem of leakage caused by the first mounting part and the connecting pipe colliding head-on, the indoor unit 600 also includes a protective part, which is mounted on the connecting pipe and located between the first mounting part and the inner chassis.

[0080] In one embodiment, the protective member is made of rubber material, and is provided with a mounting groove corresponding to the shape of the connecting pipe. The connecting pipe is inserted into the mounting groove, which not only provides protection but also limits the movement of the connecting pipe. On the basis of the first mounting member, the fixing effect is better.

[0081] In another embodiment, the protective member is made of foam, silicone, etc., and a mounting groove can also be provided.

[0082] To protect the refrigerant hose 200 and connecting pipe, the indoor unit 600 also includes a protective housing. This housing is located in the mounting area and secured to the inner chassis 610. The mounting assembly 620 is located within the housing. The inner chassis 610 has an inward recessed surface to form the mounting area, which accommodates the protective housing. This allows the housing to be mounted unobtrusively on the inner chassis 610, ensuring both protection and aesthetic appeal.

[0083] In one embodiment, the protective shell is fixed to the inner chassis 610 by screwing, which is simple to install and low in cost.

[0084] The fixing method using screws alone is difficult to assemble. In this embodiment, an inserting protrusion is provided on the inner chassis, and a matching inserting groove is provided on the bottom of the protective shell.

[0085] During installation, the plug-in groove at the bottom of the protective shell is aligned with the plug-in protrusion of the inner chassis. The plug-in groove at the bottom of the protective shell can extend along the width of the protective shell, or can be set in the width direction. In this way, the protective shell can be matched with the plug-in protrusion and the plug-in groove, and the top of the protective shell can be pushed close to the inner chassis to conveniently perform the screw tightening operation, making installation more convenient.

[0086] It should be noted that the air conditioner 100 can be a split-type air conditioner for easy user installation. It uses a flexible refrigerant pipe to connect the indoor heat exchanger of the air conditioner indoor unit 600 and the outdoor heat exchanger of the air conditioner outdoor unit 300, and refrigerant is injected into the refrigerant circuit before the device leaves the factory. This allows users to install the device themselves by simply securing the indoor unit 600 and the outdoor unit 300 separately, eliminating the need to assemble the refrigerant pipe and inject refrigerant. This reduces installation complexity and facilitates user-friendly installation. However, the present design is not limited to this. In other embodiments, the air conditioner can also be a conventional split-type air conditioner.

[0087] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
