[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] At present, in the air conditioner, the indoor unit and the outdoor unit are assembled separately; during installation, it is necessary to first install the indoor unit and the outdoor unit separately, then connect the pipelines between the indoor unit and the outdoor unit, and finally perform the exhaust and refrigerant filling operations to ensure the normal operation of the air conditioner.

[0031] However, the connection of air conditioning pipelines and the filling of refrigerant require professional personnel to operate, which is inconvenient to install and has high labor costs. In the traditional solution, the refrigerant circuit between the indoor unit and the outdoor unit needs to be connected through a dedicated copper tube. The copper tube is a hard tube and is easily broken under stress. As a result, the indoor unit and the outdoor unit 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 tube in the traditional solution. The flexibility of the refrigerant hose allows the indoor unit and the outdoor unit to be connected together, so that the process of pipeline connection and refrigerant filling of the indoor unit and the outdoor unit can be completed in advance before leaving the factory. In this way, users only need to install the indoor unit and the outdoor unit after purchase, which is convenient for users to install by themselves.

[0032] After the indoor unit and the outdoor unit are connected in advance with the refrigerant hose and the refrigerant is pre-filled in the refrigerant hose, the indoor unit and the outdoor unit circuit, 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 being connected to the indoor unit and the outdoor unit. It is also necessary to consider the convenience of installation, reduce the cost of parts processing, and reduce the assembly process.

[0033] 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 and to ensure the quality of the product.

[0034] 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.

[0035] For reference, in the traditional scheme, the outdoor unit 300 and the indoor unit 600 are connected by a dedicated copper tube. First, when the air conditioner is working, the compressor in the outdoor unit 300 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 300, and the fan discharges the heat generated during compression to the outdoor space, turning the refrigerant into a liquid with a lower temperature, and enters the evaporator of the indoor unit 600 through the copper tube (high-pressure tube or liquid tube). 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 600 can blow the "cold air" to the indoor space, achieving the cooling effect. Then the vaporized refrigerant comes out of the evaporator of the indoor unit 600, and the refrigerant passes through another relatively thick copper tube (low-pressure tube or air 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.

[0036] 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 to complete the refrigerant circulation loop of the indoor unit 600 and the outdoor unit 300, so that users can install it themselves 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, and avoid loosening, thereby improving the quality of the product.

[0037] In one embodiment, the fixing component 340 may be a cable tie, a metal buckle, or the like.

[0038] Reference Figure 3 In the present embodiment, in order to facilitate fixation and ensure a 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.

[0039] 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 arranged at intervals along the extending direction of the refrigerant hose 200 .

[0040] 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 .

[0041] 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 of the air-conditioning outdoor unit 300, the fixing component 340, such as the first fixing component 350 and the second fixing component 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.

[0042] 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.

[0043] Specifically, 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. 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.

[0044] 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, thereby ensuring 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, in the subsequent process of moving the outdoor unit 300, it is not easy to get loose, thereby ensuring the quality of the product.

[0045] Specifically, the pre-positioning structure 400 includes a first pre-positioning structure 410 , which is disposed on one side of the first fixing member 350 , and the screw locking structure 500 includes a first locking structure 510 , which is disposed on the other side of the first fixing member 350 .

[0046] 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 arranged between the other connecting section 352 and the partition plate 330.

[0047] In a specific solution, the long strip portion of the partition plate 330 protrudes outward, which is equivalent to the handle of a handbag. When installing, the connecting section 352 of a fixing member is inserted into the limiting opening 333 formed by the "handle" and the partition plate 330, and the limiting section 351 abuts against the limiting opening 333, so that the first fixing member 350 will be pre-fixed on the partition plate 330. A screw hole is provided on the other opposite connecting section 352. When installing, it is only necessary to tighten the screws to achieve the connection and fixation between the first fixing member 350 and the partition plate 330, which is more convenient to install. The first fixing member 350 fixes the pipeline 320 of the outdoor unit 300 to ensure that the pipeline 320 is not easy to detach from the partition plate 330. Compared with other solutions, on the one hand, the matching area of ​​the limiting opening 333 and the connecting section 352 is large, and the installation is convenient. During installation, it is only necessary to insert one end of the connecting section 352 into the limiting opening 333. Even if the compressor is closer to the chassis, it is also very convenient to install compared with other solutions.

[0048] 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 .

[0049] 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.

[0050] 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, the buckle groove 334 passes through the partition plate 330, and 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.

[0051] The buckle 364 extends on the folding edge section 363 toward the partition plate 330, that is, the buckle 364 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 attached to or close to the partition plate 330, and the screw locking structure 50 on the folding edge section 363 0 is configured as a screw hole, so that when the buckle 364 cooperates with the buckle groove 334, the screw holes of the folded edge section 363 and the partition plate 330 are relatively positioned, and the locking screws can realize 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 folded edge 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.

[0052] Furthermore, in order to ensure the fixing effect of the second fixing member 360 on the refrigerant hose 200, the fixing section 361 and the partition plate 330 are provided with abutting protrusions 362 facing each other in the corresponding areas, and the abutting protrusions 362 abut the protective sleeve 220. In this way, the limiting section 351 of the second fixing member 360 can better apply a pre-tightening force to the protective sleeve 220 of the refrigerant hose 200, and the cooperation of the abutting protrusions 362 can also ensure that the refrigerant hose 200 is not easy to move. In this way, only one second fixing member 360 is needed to make the part of the refrigerant hose 200 on the partition plate 330 tightly fixed, and the second fixing member 360 is easy to install and has low processing cost.

[0053] Specifically, in the traditional solution, the outdoor unit 300 divides the outer case 310 into chambers through a partition plate 330. A fan and a heat exchanger are arranged in one chamber, and a compressor and electronic control components are arranged in the other chamber. In the present 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. If the traditional solution is adopted at this time, the routing process of the refrigerant hose 200 will be difficult to fix. Therefore, in the present 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 assembly 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 separate, thereby ensuring the quality of the product.

[0054] 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, and both the mounting lug 371 and the partition plate 330 are provided with screw holes for screws to pass through to lock the partition plate 330 to the side plate 370 of the heat exchanger.

[0055] 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 clamping structure is also provided between the side plate 370 of the heat exchanger and the partition plate 330.

[0056] 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 .

[0057] 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, so that 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.

[0058] In another embodiment, the snap-in structure may also be a slide groove of the side plate 370 of the heat exchanger and a slider 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.

[0059] Reference Figure 7 and Figure 8 It is not difficult to imagine that the refrigerant hose 200 needs to have a avoidance opening 393 in the outer case 310 when passing through the outer case 310 and entering the inner part. The case 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 case 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.

[0060] Specifically, in one embodiment, the protective cover 380 is made of rubber, has a certain hardness, and also has protective capabilities.

[0061] In other embodiments, the protective cover 380 may also be made of materials such as plastic.

[0062] In order to facilitate the installation of the protective cover 380 , in one solution, the protective cover 380 can be embedded in the avoidance opening 393 by utilizing the flexible deformation of its own material.

[0063] In this solution, the protective cover 380 is provided with a section. When the protective cover 380 is installed, the section can be staggered, so that the protective cover 380 is easy to embed in the avoidance opening 393, thereby facilitating the installation of the protective cover 380.

[0064] 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 .

[0065] In another embodiment, the protective cover 380 may be disposed on a side of the outer chassis 310 .

[0066] 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.

[0067] In one embodiment, the limiting structure includes a first annular protrusion 394 disposed at the avoidance opening 393 and a first annular groove 391 disposed on the protective cover 380 , and a first annular protrusion 394 matches with a first annular groove 391 .

[0070] Regarding the connection between the indoor unit 600 and the refrigerant hose 200 .

[0071] Reference Fig. 9 The indoor unit 600 includes an inner case 610 and a mounting assembly 620. The outer surface of the inner case 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 case 610 to fix the refrigerant hose 200 and the connecting pipe to the inner case 610.

[0072] In one embodiment, the mounting assembly 620 may be a cable tie, a metal buckle, or the like.

[0073] In this embodiment, in order to facilitate fixation and ensure a good fixing 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.

[0074] 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 .

[0075] In another embodiment, the mounting assembly 620 may be a unitary member formed by integrating the first mounting member and the second mounting member.

[0076] The mounting component 620 is generally made of metal or hard plastic. By arranging a pre-positioning structure on the mounting component 620, during the installation of the air conditioner outdoor unit, the mounting component 620, such as the first mounting part and the second mounting part, can be pre-fixed on the inner chassis 610. 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.

[0077] Specifically, the refrigerant hose 200 includes an inner tube assembly 210 and a protective sleeve 220 sleeved on the outer surface of the inner tube assembly 210. Part of the inner tube assembly 210 is exposed from the protective sleeve 220 and connected to the pipeline 320 of the indoor unit 600. The first mounting member is located at the pipeline part of the indoor unit 600, and the second mounting member is located at the protective sleeve. The first mounting member is fixed to the inlet and outlet copper pipes (liquid pipe / gas pipe) of the indoor unit 600 and is close to the connection of the refrigerant hose 200, so that the copper pipe part of the indoor unit 600 is stable and not easy to shake; and the second mounting member is fixed to the protective sleeve 220 to ensure the stability of the refrigerant hose 200 in the inner chassis, so that the refrigerant hose 200 and the inlet and outlet copper pipes of the indoor unit 600 are fixed on the inner chassis, and the connection is not easy to be separated, so as to ensure the connection stability. In the subsequent process of moving the indoor unit 600, it is not easy to loosen, so as to ensure the quality of the product.

[0078] 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 sleeved on the connecting pipe and located between the first mounting part and the inner chassis.

[0079] 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 can not only provide protection but also limit the movement of the connecting pipe. On the basis of the first mounting member, the fixing effect is better.

[0080] In another embodiment, the protective member is made of foam, silicone, etc., and a mounting groove can also be provided.

[0081] In order to protect the refrigerant hose 200 and the connecting pipe, the indoor unit 600 further includes a protective shell, which is arranged at the installation position and fixed to the inner case 610, and the mounting assembly 620 is located inside the protective shell. The surface of the inner case 610 is recessed inward to form the installation position, and the installation position is adapted to the protective shell, so that the installation of the protective shell on the inner case 610 does not appear abrupt, which can not only play a protective effect, but also ensure the appearance.

[0082] In one embodiment, the protective shell is fixed to the inner chassis 610 by screwing, which is simple to install and low in cost.

[0083] The fixing method using only screws 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.

[0084] 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.

[0085] It should be noted that the air conditioner 100 can be a split air conditioner that is easy for users to install personally. 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. In this way, when the user installs the device by himself, he only needs to fix the air conditioner indoor unit 600 and the outdoor unit 300 respectively, without assembling the refrigerant pipe and filling the refrigerant, thereby reducing the difficulty of installation and realizing personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner can also be an ordinary split air conditioner.
