[0036] In the connection pipe assembly of the split mobile air conditioner on the market, each refrigerant pipe, electric wire, and drain pipe are directly passed through the inside of the sheath, and there is no connection, fixation, or isolation between them. The electric wire in the connection pipe assembly is prone to curling with the drain pipe and the refrigerant pipe, resulting in local bulging inside, which cannot be repaired by the user and affects the user experience.
[0037] In view of this, the embodiments of the present utility model provide a refrigerant hose assembly and an air conditioner. By providing a line anti-winding member, the line and the refrigerant hose or the line and the drain pipe can be fixed together, preventing the line from winding around other pipelines and reducing the possibility of scratching between the line and the pipeline.
[0038] To better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings.
[0039] As Figures 1 to 2 shown, the embodiments of the present utility model propose a refrigerant hose assembly, and the refrigerant hose assembly includes:
[0040] A protective member 200, the protective member 200 has a receiving cavity, and the material of the protective member 200 can be the same as the outer sleeve part of the existing circular hose, such as rubber material;
[0041] The refrigerant hose 100 is disposed in the receiving cavity. The refrigerant hose 100 can be applied to a split-type outdoor unit and an indoor unit to form a refrigerant circuit. The refrigerant hose 100 is a flexible hose, so the air conditioner using the refrigerant hose 100 has mobility;
[0042] The drain pipe 300 is disposed on one side of the refrigerant hose 100. The drain pipe 300 is connected between the indoor unit and a building drainage system. In addition, the drain pipe 300 can be a flexible pipe for easy installation. Alternatively, the drain pipe 300 can also be wound with a wire to increase the structural strength and prevent cracking or deformation due to compression;
[0043] The line 400, the refrigerant hose 100, the drain pipe 300 and the line 400 are arranged side by side in the receiving cavity; and
[0044] The pipeline anti-winding member 500 connects one of the refrigerant hose 100 and the drain pipe 300 to the line 400 through the pipeline anti-winding member 500.
[0045] In the technical solution adopted in this embodiment, through the setting of the pipeline anti-winding member 500, the line 400 and the refrigerant hose 100 or the line 400 and the drain pipe 300 can be fixed together, preventing the line 400 from winding around other pipelines and reducing the possibility of scratching between the line 400 and the pipelines. It can be understood that the pipeline anti-winding member 500 can fix one of the refrigerant hose 100 and the drain pipe 300 to the line 400, avoiding the curling of the line 400 and the refrigerant pipe during the installation process, improving the installation convenience. Since the line 400 and the pipelines will not curl, the possibility of local overheating is reduced, the energy efficiency of the air conditioner is improved, and the energy consumption is reduced.
[0046] In an embodiment of the present invention, the pipeline anti-winding member 500 is configured as any one of a corrugated pipe, a heat shrinkable sleeve and a wire management device. It can be understood that the pipeline anti-winding member 500 in this embodiment can be a corrugated pipe, which has a certain rigidity in addition to elasticity, and can prevent damage to the pipeline or the line 400 caused by stepping on. In another embodiment, the pipeline anti-winding member 500 can also be a heat shrinkable sleeve, which has good stretchability and can shrink after heating. It can not only fix the wire reel and the corresponding pipeline together, but also reduce the volume after fixation and reduce the space occupation. Of course, in other embodiments, the pipeline anti-winding member 500 can also be a wire management device, which can facilitate the penetration of the line 400 and the corresponding pipeline, with simple process and time saving. In specific applications, it can be selectively optimized according to the actual situation and is not limited here.
[0047] In an embodiment of the present invention, refer to Figures 1 to 3, the refrigerant hose 100 includes a thin tube 120 and a thick tube 110 arranged side by side, and at least one of the thin tube 120 and the thick tube 110 is covered together with the line 400 through a pipeline anti-winding member 500. During the formation of the loop of the refrigerant hose 100, there will be a hot loop and a cold loop. One of the thin tube 120 and the thick tube 110 serves as the hot loop, and the other of the thin tube 120 and the thick tube 110 serves as the cold loop. To avoid interference, a partition plate can be provided in the receiving cavity of the protective member 200. Refer to Figure 3 , which can play a role in separating the heat source. It can be understood that the partition plate divides the receiving cavity into a first installation cavity and a second installation cavity. The thin tube 120, the drain pipe 300, and the line 400 can be arranged in the first installation cavity. At this time, one of the thin tube 120 and the drain pipe 300 and the line 400 are fixed together through the pipeline anti-winding member 500. Of course, in other embodiments, the thin tube 120, the thick tube 110, the drain pipe 300, and the line 400 can be arranged in the same receiving cavity. At this time, the line 400 can be fixed to the thick tube 110, the line 400 can also be fixed to the thin tube 120, the line 400 can also be fixed to the drain pipe 300, and the line 400 can also be fixed to the thick tube 110 and the thin tube 120 at the same time. In specific applications, it can be preferentially selected according to the actual situation and is not limited here.
[0048] In an embodiment of the present invention, the refrigerant hose assembly further includes a first protective sleeve that covers the drain pipe 300. The drain pipe 300 has relatively low rigidity and is prone to cracking and then leaking water when subjected to external impact or trampling. Therefore, a first protective sleeve can be covered outside the drain pipe 300. The first protective sleeve can wrap the entire drain pipe 300, improve the pressure resistance of the drain pipe 300, prevent the drain pipe 300 from cracking and leaking water, and improve the service life of the drain pipe 300. As an optional method, the first protective sleeve is configured as any one of a metal bellows, a heat shrinkable sleeve, and a wire organizer, and is preferentially selected for use according to specific applications and is not limited here.
[0049] In an embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 4, the refrigerant hose assembly further includes a second protective sleeve 600, and the second protective sleeve 600 is wrapped around the outside of the refrigerant hose 100. In this way, the provided second protective sleeve 600 can protect the refrigerant hose 100 from being damaged by external forces. In one embodiment, the second protective sleeve 600 is wrapped around the outer periphery of at least one of the thin tube 120 and the thick tube 110. It can be understood that when the line 400 and the drain pipe 300 are fixed together by the anti-twisting member, the second protective sleeve 600 can wrap around one or both of the thin tube 120 and the thick tube 110. When the line 400 and the thick tube 110 are fixed together by the anti-twisting member, the second protective sleeve 600 can wrap around the thin tube 120. When the line 400 and the thin tube 120 are fixed together by the anti-twisting member, the second protective sleeve 600 can wrap around the thick tube 110. That is to say, by providing the second protective sleeve 600, the pressure resistance of the pipeline can be improved, and the safety of the pipeline under pressure can be enhanced.
[0050] In one embodiment of the present utility model, the second protective sleeve 600 is configured as any one of a metal bellows, a heat shrinkable sleeve, and a wire organizer, and can be preferentially selected and used according to specific applications, which is not limited herein. Optionally, the second protective sleeve 600 is configured as a metal bellows. The metal bellows has a certain bending angle, which can protect the refrigerant hose 100 from being damaged due to excessive bending. At the same time, the metal bellows has a certain structural strength to prevent the refrigerant hose 100 from being damaged by external forces. In addition, the flexibility of the metal bellows can ensure the normal storage of the refrigerant hose 100, not easily rebound, and reduce transportation costs.
[0051] In one embodiment of the present utility model, referring to Figure 5 and Figure 6 , the metal bellows includes a plurality of corrugated segments connected in sequence. The corrugated segment includes at least one wave crest portion 610 and at least one wave trough portion 620 formed alternately along the axial direction. One end of the corrugated segment is a wave crest portion 610, and a first connecting flange 630 extending inward is provided at the free end of the wave crest portion 610. The other end of the corrugated segment is a wave trough portion 620, and a second connecting flange 640 extending outward is provided at the free end of the wave trough portion 620. The sum of the heights of the first connecting flange 630 and the second connecting flange 640 is greater than the maximum height difference between the wave crest portion 610 and the wave trough portion 620, so that the first connecting flange 630 of one corrugated segment can be buckled with the second connecting flange 640 of the adjacent corrugated segment. In this way, through the cooperation of the first connecting flange 630 and the second connecting flange 640, two adjacent corrugated segments can be fixed together, and the flexibility of the overall structure can also be ensured.
[0052] In one embodiment of the present utility model, referring to Figure 3, the circuit 400 includes a power line 410 and a signal line 420 arranged side by side. The pipeline anti-winding member 500 covers the power line 410 and the signal line 420. The circuit 400 can be a power line 410, a signal line 420, a control line, or a wire for other purposes, and can include one or more of these. By connecting and fixing multiple cables together with the anti-winding member, it is possible to prevent the cables from scratching or winding around each other, improving the appearance and usage safety.
[0053] In an embodiment of the present invention, the protective member 200 is configured as a flat rubber sleeve, which has a relatively flatter shape compared to other dimensions. The air conditioner using this refrigerant hose assembly has mobility, and compared with the existing circular hose, the flat rubber sleeve can reduce the gap when closing the window, improving the appearance.
[0054] To achieve the above object, an embodiment of the present invention provides an air conditioner, which includes an indoor unit, an outdoor unit, and the refrigerant hose assembly described above. The refrigerant hose assembly connects the outdoor unit and the indoor unit. Specifically, for the specific structure of the refrigerant hose assembly, refer to the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be elaborated here one by one.
[0055] It should be noted that the air conditioner of the present invention can be a split air conditioner that is convenient for users to install personally. It uses a flexible refrigerant hose 100 to connect the indoor-side heat exchanger of the indoor unit and the outdoor-side heat exchanger of the outdoor unit, and injects refrigerant 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 indoor unit and the outdoor unit respectively, without the need to assemble the refrigerant pipe and add refrigerant, thus reducing the installation difficulty and realizing personal installation by the user. However, this design is not limited to this. In other embodiments, the air conditioner of the present invention can also be a common split air conditioner.
[0056] In an embodiment of the present invention, the air conditioner further includes a compressor, and the compressor is arranged in the indoor unit. In this way, arranging the compressor in the indoor unit can reduce the weight of the outdoor unit, thus facilitating the installation of the outdoor unit. At the same time, since the outdoor unit usually needs to be fixed on a bracket, reducing the weight of the outdoor unit can reduce the pressure on the bracket and prevent the bracket from cracking due to excessive pressure, thereby improving the service life of the bracket. In addition, when the compressor is arranged in the indoor unit, the air conditioner will generate relatively large noise indoors during operation, affecting the user's use. For this reason, a noise reduction structure can also be set up. Through the noise reduction structure, the noise generated by the compressor during the operation of the air conditioner can be absorbed, providing a comfortable and quiet usage environment for the user. As an optional method, the noise reduction structure can be set as sound-absorbing cotton or sound-insulating cotton arranged in the indoor unit, etc., which is not limited here.
[0057] The above is only an exemplary embodiment of the present utility model, and does not thus limit the patent scope of the embodiments of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the embodiments of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the embodiments of the present utility model.
