[0040] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. 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 mutually 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.

[0043] Currently, the connecting pipe assemblies of the indoor and outdoor air conditioner units on the market are fixed by directly pressing the outer protective cover with sheet metal clips; the refrigerant pipe inside is in a free-moving state. When the user bends the connecting pipe assembly when storing or moving the machine, the internal refrigerant pipe is subjected to force and pulled, resulting in refrigerant leakage.

[0044] To this end, the present invention proposes an air conditioner, which aims to solve the problem of refrigerant leakage caused by the refrigerant tube group being pulled during transportation or bending by limiting the two ends of the refrigerant tube group.

[0045] See also Figures 1 to 6 In one embodiment of the present invention, the air conditioner includes an outdoor air conditioner 120 (not shown in the figure) and an indoor air conditioner 110. The outdoor air conditioner 120 and the indoor air conditioner 110 are connected by a connecting pipe group 200. The connecting pipe group 200 includes a protective cover 210 and a refrigerant pipe group 220, an electric wire 240 and a drain pipe all arranged in the protective cover 210. In order to prevent the internal refrigerant pipe group 220 from being in a free movement state relative to the protective cover 210, the refrigerant pipe group 220 is passed through a first fixed pipe member 300, and the refrigerant pipe group 220 is fixed relative to the first fixed pipe member 300; the first fixed pipe member 300 is fixed relative to the indoor air conditioner 110; the refrigerant pipe group 220 is passed through a second fixed pipe member 400, and the refrigerant pipe group 220 is fixed relative to the second fixed pipe member 400; the second fixed pipe member 400 is fixed relative to the outdoor air conditioner 120.

[0046] The technical solution of the present invention is that the air-conditioning outdoor unit 120 and the air-conditioning indoor unit 110 are connected by a connecting pipe group 200. In order to avoid the relative movement of the protective cover 210 and the refrigerant pipe group 220, which may cause the refrigerant pipe group 220 to be pulled and leak the refrigerant; the refrigerant pipe group 220 on the side of the air-conditioning indoor unit 110 is fixed by a first fixed pipe member 300, and the refrigerant pipe group 220 on the side of the air-conditioning outdoor unit 120 is fixed by a second fixed pipe member 400; thereby avoiding the relative movement of the protective cover 210 and the refrigerant pipe group 220 when the user stores or moves the machine and the connecting pipe group 200 is bent, and the internal refrigerant pipe group 220 is subjected to force and pulled, thereby causing refrigerant leakage.

[0047] In one embodiment, the first fixed pipe 300 and the second fixed pipe 400 are embedded in the protective cover 210; the refrigerant pipe assembly 220 is fixed to the first fixed pipe 300 and the second fixed pipe 400 by snapping, gluing, clamping, etc.; in other embodiments, the first fixed pipe 300 and the second fixed pipe 400 are embedded in the protective cover 210; or, one of the first fixed pipe 300 or the second fixed pipe 400 is inside the protective cover 210, and the other is outside the protective cover 210.

[0048] Reference Figure 3 and Figure 5 The air conditioner includes an indoor air conditioner unit 110 and an outdoor air conditioner unit 120. The refrigerant pipe group 220 (usually a copper pipe) passes through the air conditioner casing (the bent part is hidden in the figure) to connect the indoor air conditioner unit 110 and the outdoor air conditioner unit 120. The air conditioner includes an indoor air conditioner unit 110 and an outdoor air conditioner unit 120. The indoor air conditioner unit 110 and the outdoor air conditioner unit 120 can be set as an integrated whole. In this case, the air conditioner is a mobile air conditioner and does not require an external exhaust pipe or outdoor unit. All components are integrated into one unit; but not limited to this, the indoor air conditioner unit 110 and the outdoor air conditioner unit 120 are connected by a flexible refrigerant pipe; and the compressor of the air conditioner can be further arranged in the indoor air conditioner unit 110.

[0049] This makes the split-type 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 allows users to install the unit themselves by simply securing the indoor and outdoor units separately, eliminating the need to assemble refrigerant piping or inject refrigerant. This simplifies installation and makes it easy for users to install the unit themselves.

[0050] Placing the compressor in the indoor unit reduces the weight of the outdoor unit 120, making it easier for users to move it and find a suitable installation location. This reduces installation effort and labor costs, especially in areas with high labor costs. To reduce noise, the indoor unit's compressor is treated with noise-reducing materials, for example, or with a buffer structure to reduce the transmission of compressor vibration.

[0051] In order to avoid the situation where the internal water pipes are subjected to force and pulled when the user stores or moves the machine, there are 200 pieces of bending connecting pipe groups, which may cause the water pipe joints to be broken.

[0052] The first fixed pipe member 300 is provided with a first refrigerant pipe hole 320 and a second refrigerant pipe hole 330 at intervals. The first refrigerant pipe 221 is provided in the first refrigerant pipe hole 320, and the second refrigerant pipe 222 is provided in the second refrigerant pipe hole 330. A drain pipe hole 310 is provided between the first refrigerant pipe hole 320 and the second refrigerant pipe hole 330. To prevent the wire 240 from contacting the refrigerant pipe assembly 220 and causing a risk of electrical leakage within the refrigerant pipe assembly 220, the wire 240 is passed through the drain pipe hole 310.

[0053] In order to facilitate the movement of the air conditioner indoor unit 110 and the air conditioner outdoor unit 120, the connecting pipe group adopts a flexible refrigerant pipe group, that is, the refrigerant pipe group is configured as a refrigerant hose assembly, and the refrigerant hose assembly is pre-filled with refrigerant.

[0054] The wire hole is arranged between the two refrigerant pipes, and the wire 240 enters the protective cover 210 directly through the wire hole, and the wire 240 will not come into contact with the refrigerant pipe group 220. The design of the first fixed pipe member 300 and the second fixed pipe member 400 ensures that the refrigerant pipe and the drain pipe will not interfere with each other before entering the protective cover 210. By setting the first end of the first refrigerant pipe 221 in the first refrigerant pipe hole 320, the first end of the second refrigerant pipe 222 in the second refrigerant pipe hole 330; and the first end of the drain pipe hole 310 between the first refrigerant pipe hole 320 and the second refrigerant pipe hole 330, and fixing these pipelines, it can effectively prevent them from crossing and colliding in the area not covered by the protective cover 210.

[0055] Reference Figure 4To facilitate assembly, the first pipe fixing member 300 has a first latching opening 340 corresponding to each of the drain pipe hole 310, the first refrigerant pipe hole 320, and the second refrigerant pipe hole 330. The diameter of the first latching opening 340 is smaller than the corresponding pipe hole. The first pipe fixing member 300 is made of rubber, and the refrigerant pipe hole is a U-shaped latching groove. During installation, the first pipe fixing member 300 can be clipped onto the refrigerant pipe assembly 220 to prevent detachment. The elastic material prevents scratching the refrigerant pipes.

[0056] In other embodiments, the refrigerant pipe holes and drain pipe holes 310 are arranged according to the specific layout of the connecting pipe assembly 200. In this embodiment, the drain pipe hole 310 has a different shape and / or size than the first refrigerant pipe hole 320 and the second refrigerant pipe hole 330. During installation, the refrigerant pipe and drain pipe are respectively snapped into corresponding U-shaped slots to achieve isolation and fixation of the refrigerant pipe and drain pipe. To prevent accidental snapping into the incorrect position during installation, the refrigerant pipe hole and drain pipe hole 310 are designed with different shapes and sizes according to the size of the refrigerant pipe and connecting pipe, ensuring foolproof installation.

[0057] Reference Figure 3 and Figure 4 On the air conditioner indoor unit 110 side, in one embodiment, the first pipe fixing member 300 is a rubber block. A refrigerant pipe hole and a drain pipe hole 310 are axially provided on the first pipe fixing member 300. To facilitate assembly and prevent disengagement, the refrigerant pipe hole and the drain pipe hole 310 are provided with a first latching opening 340. The diameter of the first latching opening 340 is smaller than the diameter of the corresponding pipe hole. To prevent relative movement between the protective sleeve 210 and the first pipe fixing member 300, the first pipe fixing member 300 is embedded in the first end of the protective sleeve 210. The air conditioner also includes a pipe clamp 500 that clamps and secures the protective sleeve 210 and the first pipe fixing member 300. The first pipe fixing member 300 is made of rubber and secures the two refrigerant pipes. This ensures that the extended lengths of the two refrigerant pipes are the same, thus making the dimensions controllable during production. The connecting copper pipes can be made to the same height, which makes it easier to insert and weld the refrigerant pipes.

[0058] The pipe clamp 500 includes a first sub-component 510 and a second sub-component 520. One end of the first sub-component 510 and one end of the second sub-component 520 are clamped and fixed, and the other end is locked and fixed, thereby clamping the first fixed pipe component 300 and the protective cover 210, so that the protective cover 210 and the first fixed pipe component 300 will not move relative to each other, and at the same time, the refrigerant pipe group 220 and the drain pipe of the first fixed pipe component 300 will not move relative to each other.

[0059] In other embodiments, the first fixed pipe member 300 and the protective cover 210 may be clamped and fixed by a tightening belt; the pipe clamp 500 clamps the protective cover 210 and the first fixed pipe member 300, and the protective cover 210 and the first fixed pipe member 300 do not move relative to each other, and the refrigerant pipe group 220 and the drain pipe of the first fixed pipe member 300 do not move relative to each other; the first clamping plate 600 is connected to the air conditioner indoor unit 110, and clamps and fixes the protective cover 210 and the first fixed pipe member 300.

[0060] Reference Figure 5 and Figure 6 In order to improve the aesthetics, a piping cover 800 is provided on the side of the air conditioner indoor unit 110 and is connected to the panel of the air conditioner indoor unit 110 to cover the exposed refrigerant tube group 220, drain pipe and wire 240. After the piping cover 800 is covered, the piping cover 800 extends from the protective cover 210 to the bottom avoidance opening. From the outside, users can only see the protective cover 210 and the piping cover 800, but not the avoidance opening, wire holes, scattered drainage pipes, wires 240 and exposed refrigerant tube group 220.

[0061] Furthermore, the first pipe fixing member 300 prevents interference between the drain pipe, refrigerant pipe assembly 220, and electrical wires 240 before they enter the protective cover 210. By providing relatively spaced refrigerant pipe holes and drain pipe holes 310 on the first pipe fixing member 300 and securing these pipes, they can be effectively prevented from intersecting or colliding in the area not covered by the protective cover 210.

[0062] Reference Figure 3 and Figure 4 In order to secure the first pipe member 300, in this embodiment, the air conditioner further includes a first clamping plate 600, which is connected to the air conditioner indoor unit 110 to secure the first pipe member 300. In other embodiments, the first pipe member 300 may also be secured by gluing or other methods. After the first pipe member 300 is secured by the first clamping plate 600, when the pipe cover 800 is subsequently installed, there is no need to manually press the drain pipe and wires 240 to avoid pressing on the drain pipe and wires 240 and posing a safety hazard to the wires. Since there is no need to press the drain pipe and wires 240 before installing the pipe cover 800, production efficiency is improved. The pipe cover 800 is directly connected to the air conditioner indoor unit 110, shielding and protecting the exposed refrigerant pipe group 220, water pipes, and wires 240 in these areas. This not only improves the interior aesthetics but also prevents direct damage to the pipes and wires 240 from external factors.

[0063] Reference Figure 1In order to facilitate installation, the pipe cover 800 and the air conditioner indoor unit 110 are fixed by snapping together. In a further solution, on the basis of the snapping together of the pipe cover 800 and the air conditioner indoor unit 110, screw locking is added. In this way, the snap-fitting fixation reduces the cumbersome operation during the locking process and facilitates the locking and fixing. Moreover, while ensuring the fixing effect, the number of screws required is reduced, thereby improving the installation efficiency to a certain extent.

[0064] Specifically, buckles (not shown in the figure) are provided on opposite sides of the piping cover 800, and corresponding slots are provided on the air conditioner indoor unit 110. The slots are located on both sides of the connecting pipe group 200. The buckles and the slots cooperate to fix the piping cover 800 to the air conditioner indoor unit 110.

[0065] Reference Figure 5 and Figure 6 On the side of the air conditioner outdoor unit 120, in one embodiment, the second fixed pipe member 400 is provided with refrigerant pipe holes and wire pipe holes 430 at intervals, the refrigerant pipe group 220 is provided in the refrigerant pipe hole; the wire 240 passes through the wire pipe hole 430; the second fixed pipe member 400 is clamped and fixed to the refrigerant pipe group 220 by adhesive, tightening tape, etc., and the wire 240 and the refrigerant pipe group 220 are separated. The wire 240 will not come into contact with the refrigerant pipe group 220, resulting in leakage of the refrigerant pipe group 220. Specifically, the refrigerant tube group 220 includes a first refrigerant tube 221 and a second refrigerant tube 222 with different tube diameters; the refrigerant tube holes include a third refrigerant tube hole 410 and a fourth refrigerant tube hole 420 which are spaced apart on the second fixed tube part 400, the first refrigerant tube 221 is arranged in the third refrigerant tube hole 410, and the second refrigerant tube 222 is arranged in the fourth refrigerant tube hole 420; the wire tube hole 430 is arranged between the third refrigerant tube hole 410 and the fourth refrigerant tube hole 420.

[0066] Reference Figure 6 To facilitate tube assembly, the second pipe fixing member 400 has a second latching opening 440 corresponding to each of the third and fourth refrigerant tube holes 410 and 420. The diameter of the second latching opening 440 is smaller than the corresponding hole. The second pipe fixing member 400 is made of rubber and secures the two refrigerant tubes, ensuring that their extended lengths are the same. This allows for dimensional control during production and allows the refrigerant tubes to be made uniform in height, making refrigerant insertion and welding easier.

[0067] To facilitate separation of the drain pipe from the refrigerant pipe and electrical wires 240, a pipe notch 211 is provided at the second end of the protective cover 210. The drain pipe passes through the notch 211 and is exposed outside the protective cover 210. This notch 211 allows the drain pipe to pass through and be exposed outside the protective cover 210. This ensures that the drain pipe can drain condensed water smoothly without being restricted by the protective cover 210.

[0068] Reference Figure 5 and Figure 6 Additionally, a spring 250 is sleeved around the outside of drain pipe 230. Spring 250 provides a certain degree of elasticity and provides a cushioning effect. When water flows through drain pipe 230 or encounters external vibrations, spring 250 absorbs some of the vibration energy, reducing the noise generated by the vibration in drain pipe 230. While spring 250 itself does not directly participate in the drainage process, it ensures that drain pipe 230 maintains a certain shape and stability, thereby facilitating smooth drainage of water. In some cases, the design of spring 250 can also guide the direction of water flow, improving drainage efficiency.

[0069] In order to facilitate the user to move the air conditioner indoor unit 110, the bottom of the air conditioner indoor unit 110 is provided with moving wheels (not shown in the figure), such as universal wheels.

[0070] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
