[0047] In existing air conditioners, the connecting pipe assembly includes wiring, refrigerant pipes, and a drain pipe, used to connect the indoor and outdoor units to transmit electrical energy and refrigerant. The refrigerant pipes and drain pipes are relatively weak and prone to cracking when subjected to external force, leading to refrigerant or water leakage.

[0048] In view of this, the present application provides a refrigerant hose assembly and an air conditioner. By providing a pressure-resistant flexible component, it can prevent pressure in the radial direction, increase the structural strength of the drain pipe or refrigerant hose, improve the pressure resistance of the drain pipe or refrigerant hose, prevent the drain pipe from cracking and leaking water or the refrigerant hose from cracking and leaking refrigerant, improve the service life of the drain pipe or refrigerant hose, and thus improve the safety of using the refrigerant hose assembly.

[0049] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0050] As shown in Figure 1, this application embodiment proposes a refrigerant hose assembly 100, which includes:

[0051] The protective component 110 has an internal protective cavity. The material of the protective component 110 can be the same as the outer sleeve of an existing round hose, such as rubber. The protective component 110 can be a flat rubber sleeve, which has a flatter shape compared to other sizes. Air conditioners using this refrigerant hose assembly 100 have mobility, and compared to existing round hoses, the flat rubber sleeve can reduce gaps when windows are closed, improving aesthetics. Of course, the protective component 110 can also be made of plastic, pearl cotton, or heat shrink tubing, etc., and is not limited thereto.

[0052] The refrigerant hose 120 is located in the protective cavity. The refrigerant hose 120 can be used in a separate outdoor unit 200 and an indoor unit 300 to form a refrigerant circuit. The refrigerant hose 120 is a flexible hose, so the air conditioner using the refrigerant hose 120 is mobile.

[0053] A drain pipe 130 is located within the protective cavity. The refrigerant hose 120 and the drain pipe 130 are arranged side-by-side. The drain pipe 130 connects the indoor unit 300 to a building drainage system. Furthermore, the drain pipe 130 can be flexible for ease of installation; and

[0054] At least one of the pressure-resistant flexible member 140, the refrigerant hose 120 and the drain pipe 130 is externally fitted with the pressure-resistant flexible member 140, which is pressure-resistant in the radial direction and has bendable flexibility in the longitudinal direction.

[0055] In the technical solution adopted in this embodiment, the pressure-resistant flexible component 140 provides radial pressure resistance, increasing the structural strength of the drain pipe 130 or refrigerant hose 120, improving the pressure resistance of the drain pipe 130 or refrigerant hose 120, preventing the drain pipe 130 from cracking and leaking water, or the refrigerant hose 120 from cracking and leaking refrigerant, thus extending the service life of the drain pipe 130 or refrigerant hose 120 and improving the safety of the refrigerant hose assembly 100. Furthermore, the pressure-resistant flexible component 140 is flexible in the length direction, allowing it to bend along with the refrigerant hose 120, improving installation convenience.

[0056] In one embodiment, the pressure-resistant flexible element 140 can be sleeved on the outside of the drain pipe 130, the outside of the refrigerant hose 120, or both. Thus, because the pressure-resistant flexible element 140 has a certain degree of rigidity in the radial direction to prevent pressure, it improves the structural strength of the pipeline, significantly enhances the pipeline's pressure resistance, and can withstand greater external forces such as stepping or impact, reducing the risk of pipeline cracking and preventing refrigerant or water leakage. The safety of the refrigerant hose assembly 100 is effectively improved.

[0057] In one embodiment, the pressure-resistant flexible component 140 can be a metal spring or a metal bellows. Both the metal spring and the metal bellows are spiral-shaped, allowing them to be bent, but not to the extreme. They can deform and bend synchronously with the internal refrigerant hose 120 or drain pipe 130, and will not be damaged by user force. Furthermore, since the metal spring 141 or the metal bellows 143 is made of metal, it has a certain rigidity in the radial direction, resulting in good pressure resistance. The drain pipe 130 or the refrigerant hose 120 will not crack or break under external pressure. In one embodiment, the metal spring 141 or the metal bellows 143 is made of SUS304 stainless steel, which has elasticity and flexibility, pressure resistance, corrosion resistance, and good thermal conductivity. This allows the pressure-resistant flexible component 140 to adapt to changes in the piping system such as thermal expansion and contraction or mechanical vibration, maintaining the integrity and stability of the pipeline under high pressure.

[0058] In one embodiment of this application, referring to FIG2, the pressure-resistant flexible member 140 includes a metal spring 141 sleeved on the outside of the drain pipe 130. The drain pipe 130 has the function of draining water and is usually a flexible pipe. When subjected to compression or impact, it is easily flattened or cracked, thereby affecting normal drainage. Therefore, in this embodiment, the pressure-resistant flexible member 140 includes a metal spring 141. The metal spring 141 is sleeved on the outside of the drain pipe 130 and can partially or completely cover the drain pipe 130. This is equivalent to adding a pressure-resistant structure to the outside of the drain pipe 130. The radial stiffness of the metal spring 141 is used to improve the strength of the drain pipe 130, enhance the pressure resistance of the drain pipe 130, prevent the drain pipe 130 from being flattened or cracked under force, and ensure the normal drainage of the drain pipe 130.

[0059] In one embodiment of this application, referring to FIG2, the end of the metal spring 141 is fixed to the drain pipe 130 by adhesive tape 142. This secures the metal spring 141 and the drain pipe 130 as a whole, preventing the metal spring 141 from moving axially along the drain pipe 130 and affecting its pressure resistance. In one embodiment, the adhesive tape 142 can be ordinary adhesive tape or high-strength adhesive tape; no limitation is made here.

[0060] In one embodiment of this application, referring to FIG2, the pressure-resistant flexible member 140 includes a metal corrugated tube 143 sleeved on the outside of the refrigerant hose 120. The metal corrugated tube 143 is sleeved on the outside of the thick hose 121, which can improve the strength of the thick hose 121 and prevent it from being flattened or cracked.

[0061] In one embodiment of this application, referring to FIG2, the refrigerant hose 120 includes a thick hose 121 and a thin hose 122 with a smaller diameter than the thick hose 121 arranged side by side. A pressure-resistant flexible member 140 is disposed on the outside of the thick hose 121. During the formation of the circuit in the refrigerant hose 120, there are hot and cold circuits. One of the thin hose 122 and the thick hose 121 serves as the hot circuit, and the other of the thin hose 122 and the thick hose 121 serves as the cold circuit. Since the thick hose 121 has the largest diameter, when the entire refrigerant hose assembly 100 is subjected to pressure, the thick hose 121 will be subjected to pressure first. Therefore, the pressure-resistant flexible member 140 is disposed on the outside of the thick hose 121 to effectively improve the pressure resistance of the thick hose 121.

[0062] In one embodiment of this application, referring to Figures 1 and 4, a refrigerant hose assembly is applied to an air conditioner. The air conditioner includes an outdoor unit 200 with an installation port. The refrigerant hose assembly 100 also includes a sealing assembly 150, which is located outside one end of a protective member 110 and is sealed to the installation port. Existing air conditioners typically have an installation port on the outdoor unit 200, through which the refrigerant hose assembly 100 directly connects. The gap between the refrigerant hose assembly 100 and the installation port is relatively large, allowing dust, insects, and rodents to enter the air conditioner, increasing cleaning difficulty. Therefore, this embodiment provides a sealing assembly 150, which is sleeved on the outside of one end of the protective member 110. The sealing assembly 150 connects the protective member 110 and the installation port, effectively reducing the gap between them, improving the sealing effect, preventing dust, insects, and rodents from entering the air conditioner, and ensuring its normal operation.

[0063] In one embodiment of this application, referring to FIG3, the sealing assembly 150 includes:

[0064] The flexible telescopic sleeve 151 has one end fitted over the outside of the protective component 110, and the other end sealed to the mounting port; and

[0065] Locking member 152 connects flexible telescopic sleeve 151 and protective member 110 to fix flexible telescopic sleeve 151 to protective member 110.

[0066] Specifically, the sealing assembly 150 includes a flexible telescopic sleeve 151 and a locking element 152. The flexible telescopic sleeve 151 is extendable and bendable along its length and deformable in the radial direction, which can compensate for the gap between the protective element 110 and the mounting opening, improving the sealing effect. Furthermore, the flexible telescopic sleeve 151 can twist or bend synchronously with the protective element 110, thus preventing the gap between the protective element 110 and the mounting opening from increasing, further ensuring the sealing effect. The locking element 152 is used to fix the flexible telescopic sleeve 151 and the protective element 110. It can be understood that the flexible telescopic sleeve 151 is fixed to the outside of the protective element 110 by the locking element 152. Compared to directly setting sealing rings or other sealing elements around the mounting opening, the flexible telescopic sleeve 151 in this solution is fixed to the outside of the protective element 110 by the locking element 152, ensuring both sealing effect and installation stability.

[0067] To facilitate the bending and twisting of the flexible telescopic sleeve 151 with the protective member 110 and ensure the connection stability of the sealing assembly 150, in one embodiment, the flexible telescopic sleeve 151 is configured as a bellows. This bellows has multiple outwardly bent and protruding connecting sections; that is, the cross-section of the bellows along its axial direction is generally wavy, making the flexible telescopic sleeve 151 more adaptable to the twisting or bending of the protective member 110, thereby ensuring the connection stability of the sealing assembly 150. In other embodiments, the flexible telescopic sleeve 151 can also be configured as a serpentine tube with a spirally wound strip structure.

[0068] In one embodiment of this application, referring to FIG5, the locking member 152 includes a first covering portion 1521 and a second covering portion 1522 that are detachably connected. The first covering portion 1521 and the second covering portion 1522 are spliced ​​and fixed together to cover and fix the protective member 110. This allows for the installation of the locking member 152. It is understood that during assembly, the flexible telescopic sleeve 151 is first placed over the protective member 110, and then the first covering portion 1521 and the second covering portion 1522 are respectively wrapped over the flexible telescopic sleeve 151, locking the first covering portion 1521 and the second covering portion 1522 so that the flexible telescopic sleeve 151 is tightly fitted over the protective member 110. In one embodiment, the first covering portion 1521 and the second covering portion 1522 can be connected by fastening screws or bolts. Of course, in other embodiments, the first covering portion 1521 and the second covering portion 1522 can also be connected by a snap-fit ​​structure, which is not limited here.

[0069] In one embodiment of this application, referring to FIG2, the refrigerant hose 120 includes a thick hose 121 and a thin hose 122 with a diameter smaller than that of the thick hose 121 arranged side by side. The protective cavity includes at least a first sub-cavity 111 and a second sub-cavity 112 separated from each other. The thick hose 121 is located in the first sub-cavity 111, and the thin hose 122 and the drain pipe 130 are located in the second sub-cavity 112. During the formation of the circuit, the refrigerant hose 120 will have a hot circuit and a cold circuit. One of the thin hose 122 and the thick hose 121 serves as the hot circuit, and the other of the thin hose 122 and the thick hose 121 serves as the cold circuit. To prevent interference, a partition plate is provided in the protective cavity to divide the protective cavity into the first sub-cavity 111 and the second sub-cavity 112, which can serve to separate the heat sources. The first sub-cavity 111 and the second sub-cavity 112 have the same space and are respectively passed through the thin hose 122 or the thick hose 121. This allows it to be made flat instead of round, so that the gap will be very small when the window is closed. The thin flexible tube 122 and the drain tube 130 are located in the second sub-cavity 112, which allows for easy installation.

[0070] In one embodiment, the thick hose 121 includes a first metal inner tube, a first elastic protective layer on the outer surface of the first metal inner tube, and a first metal braided layer on the outer surface of the first elastic protective layer; and / or, the thin hose 122 includes a second metal inner tube, a second elastic protective layer on the outer surface of the second metal inner tube, and a second metal braided layer on the outer surface of the second elastic protective layer. Thus, the refrigerant hose 120 can be bent arbitrarily, but with a minimum bending angle, which satisfies the portability of the portable air conditioner, allowing the outdoor unit to be moved freely, while simultaneously preventing damage to the refrigerant hose 120 and subsequent leakage.

[0071] In one embodiment of this application, referring to Figures 1 to 3, the refrigerant hose assembly 100 further includes a heat insulation member 160, which is disposed outside the protective member 110. Under high humidity conditions, condensation may occur on the outside of the refrigerant hose assembly 100. Therefore, the heat insulation member 160 is provided outside the protective member 110. The heat insulation member 160 increases the thermal resistance between the interior of the protective member 110 and the external environment, effectively reducing heat transfer and preventing condensation from forming on the outside of the protective member 110.

[0072] In one embodiment of this application, the heat insulation component 160 is made of any one of heat insulation cotton, polyethylene, polyurethane, or EPDM rubber. All of the above materials have good heat insulation effects and can effectively prevent the occurrence of condensation.

[0073] In the market, the connecting pipe assemblies for split-type portable air conditioners have refrigerant pipes, electrical wires, and drain pipes directly threaded inside the sheath without any connection, fixation, or isolation between them. This makes it easy for the electrical wires in the connecting pipe assembly to become tangled with the drain pipes and refrigerant pipes, causing internal bulges that users cannot repair, thus impacting the user experience.

[0074] In view of this, embodiments of this application provide a refrigerant hose assembly and an air conditioner. By setting up a pipeline anti-winding component, the wiring and refrigerant hose or the wiring and drain pipe can be fixed together to prevent the wiring from getting tangled in other pipes and reduce the possibility of the wiring and pipes rubbing against each other.

[0075] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0076] As shown in Figures 6 and 7, this application provides a refrigerant hose assembly, which includes:

[0077] The protective element 200 has a protective cavity, and the material of the protective element 200 can be the same as the outer sleeve of an existing round hose, such as rubber.

[0078] The refrigerant hose 100 is located in the protective cavity. The refrigerant hose 100 can be used in a separate 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 is mobile.

[0079] A drain pipe 130 is located on one side of the refrigerant hose 100, connecting the indoor unit to a building's drainage system. Alternatively, the drain pipe 130 can be flexible for ease of installation. Or, the drain pipe 130 can be wrapped with metal wire to increase structural strength and prevent cracking or deformation under pressure.

[0080] Line 400, refrigerant hose 100, drain pipe 130, and line 400 are arranged side by side in the protective cavity; and

[0081] One of the pipe anti-winding component 500, refrigerant hose 100 and drain pipe 130 is connected to the line 400 via the pipe anti-winding component 500.

[0082] In this embodiment, the anti-winding component 500 secures the line 400 and refrigerant hose 100, or the line 400 and drain pipe 130, together, preventing the line 400 from getting tangled in other pipes and reducing the possibility of the line 400 and the pipes rubbing against each other. It is understood that the anti-winding component 500 secures one of the refrigerant hose 100 or drain pipe 130 to the line 400, preventing the line 400 and the refrigerant pipe from coiling during installation, thus improving installation convenience. Because the line 400 and the pipes will not coil, the possibility of localized overheating is reduced, improving the energy efficiency of the air conditioner and reducing energy consumption.

[0083] In one embodiment of this application, the anti-winding component 500 is configured as any one of a corrugated pipe, a heat-shrink tubing, and a cable organizer. It is understood that the anti-winding component 500 in this embodiment can be a corrugated pipe, which, in addition to being elastic, also possesses a certain degree of rigidity, preventing damage to the pipe or line 400 caused by stepping on it. In another embodiment, the anti-winding component 500 can also be a heat-shrink tubing. Heat-shrink tubing has good extensibility and can shrink after heating, which not only fixes the cable reel and the corresponding pipe together but also reduces the volume after fixing, minimizing space occupation. Of course, in other embodiments, the anti-winding component 500 can also be a cable organizer, facilitating the insertion of the line 400 and the corresponding pipe, simplifying the process and saving time. In specific applications, the optimal choice can be made according to the actual situation, and no limitation is made here.

[0084] In one embodiment of this application, referring to Figures 6 to 8, the refrigerant hose 100 includes a thin hose 122 and a thick hose 121 arranged side by side. At least one of the thin hose 122 and the thick hose 121 is wrapped together with the line 400 by a pipeline anti-winding member 500. During the formation of the circuit, the refrigerant hose 100 will have a hot circuit and a cold circuit. One of the thin hose 122 and the thick hose 121 serves as the hot circuit, and the other of the thin hose 122 and the thick hose 121 serves as the cold circuit. To avoid interference, a partition plate can be provided inside the protective cavity of the protective member 200, as shown in Figure 8, which can serve to separate the heat source. It can be understood that the partition plate divides the protective cavity into a first mounting cavity and a second mounting cavity. The thin hose 122, the drain pipe 130, and the line 400 can be arranged in the first mounting cavity. In this case, one of the thin hose 122 and the drain pipe 130 is fixed together with the line 400 by the pipeline anti-winding member 500. Of course, in other embodiments, the thin hose 122, the thick hose 121, the drain pipe 130, and the wiring 400 can be arranged in the same protective cavity. In this case, the wiring 400 can be fixed together with the thick hose 121, the thin hose 122, and the drain pipe 130. The wiring 400 can also be fixed together with both the thick hose 121 and the thin hose 122 simultaneously. In specific applications, the preferred option can be selected according to the actual situation, and no limitation is made here.

[0085] In one embodiment of this application, the refrigerant hose assembly further includes a first protective sleeve that covers the drain pipe 130. The drain pipe 130 has relatively weak rigidity and is prone to cracking and leakage when subjected to external impact or pressure. Therefore, a first protective sleeve can be wrapped around the drain pipe 130. This first protective sleeve completely covers the drain pipe 130, improving its pressure resistance, preventing cracking and leakage, and extending its service life. In one embodiment, the first protective sleeve can be any one of a metal corrugated pipe, a heat-shrink tubing, or a cable management device; the preferred option is selected based on the specific application, and no limitation is made here.

[0086] In one embodiment of this application, referring to Figures 6, 7, and 9, the refrigerant hose assembly further includes a second protective sleeve 600, which covers the exterior of the refrigerant hose 100. Thus, the second protective sleeve 600 provides protection for the refrigerant hose 100, preventing damage from external forces. In one embodiment, at least one of the thin hose 122 and the thick hose 121 is covered by the second protective sleeve 600. It is understood that when the line 400 and the drain pipe 130 are secured together by an anti-winding member, the second protective sleeve 600 may cover one or both of the thin hose 122 and the thick hose 121. When the line 400 and the thick hose 121 are secured together by an anti-winding member, the second protective sleeve 600 may cover the thin hose 122. When the line 400 and the thin hose 122 are secured together by an anti-winding member, the second protective sleeve 600 may cover the thick hose 121. In other words, by setting 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.

[0087] In one embodiment of this application, the second protective sleeve 600 is configured as any one of a metal corrugated tube, a heat shrink tubing, and a cable organizer. The preferred choice can be selected based on the specific application, and no limitation is made here. The second protective sleeve 600 is configured as a metal corrugated tube. The metal corrugated tube has a certain bending angle, which can protect the refrigerant hose 100 from damage due to excessive bending. At the same time, the metal corrugated tube has a certain structural strength to prevent the refrigerant hose 100 from being damaged by external forces. In addition, the flexibility of the metal corrugated tube ensures that the refrigerant hose 100 can be properly stored without easily springing back, thus reducing transportation costs.

[0088] In one embodiment of this application, referring to Figures 10 and 11, the metal corrugated pipe includes a plurality of corrugated segments connected in sequence. Each corrugated segment includes at least one crest portion 610 and at least one trough portion 620 alternately formed along the axial direction. One end of the corrugated segment is the crest portion 610, and the free end of the crest portion 610 is provided with an inwardly extending first connecting flange 630. The other end of the corrugated segment is the trough portion 620, and the free end of the trough portion 620 is provided with an outwardly extending second connecting flange 640. 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 crest portion 610 and the trough portion 620, so that the first connecting flange 630 of one corrugated segment can be engaged with the second connecting flange 640 of an 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.

[0089] In one embodiment of this application, referring to FIG8, the line 400 includes a power line 410 and a signal line 420 arranged side by side. The anti-winding component 500 covers the power line 410 and the signal line 420. The line 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 component, it is possible to prevent the cables from scratching or tangling with each other, thereby improving appearance and safety of use.

[0090] In one embodiment of this application, the protective member 200 is configured as a flat rubber sleeve. The flat rubber sleeve has a flatter shape relative to other sizes. The air conditioner using this refrigerant hose assembly is mobile, and compared to existing round hoses, the flat rubber sleeve can reduce gaps when windows are closed and improve appearance.

[0091] This application provides an air conditioner. Referring to FIG4, the air conditioner includes an indoor unit 300, an outdoor unit 200, and a refrigerant hose assembly 100 described above. The refrigerant hose assembly 100 connects the outdoor unit 200 and the indoor unit 300. Specifically, the specific structure of the refrigerant hose assembly 100 is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0092] It should be noted that the air conditioner of this application can be a split-type air conditioner that is easy for users to install themselves. It uses a flexible refrigerant hose 120 to connect the indoor heat exchanger of the indoor unit 300 and the outdoor heat exchanger of the outdoor unit 200, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when users install the equipment themselves, they only need to fix the indoor unit 300 and the outdoor unit 200 separately, without needing to install refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual installation. 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.

[0093] In one embodiment of this application, referring to Figures 3 and 4, the outdoor unit 200 has an installation port, and the installation port is provided with an installation component 220. The installation component 220 has a through hole communicating with the installation port, and the sealing assembly 150 is sealed to the through hole. In this way, the sealing assembly 150 can be fixed by the installation component 220, thereby improving the installation stability while ensuring the sealing effect; and / or

[0094] Referring to Figure 5, the air conditioner also includes a pipe clamp 410 and a pipe cover 420. The pipe clamp 410 fixes the other end of the protective component 110 to the indoor unit 300. The pipe cover 420 is connected to the indoor unit 300 and covers the other end of the pipe clamp 410 and the protective component 110. Thus, the pipe clamp 410 can clamp and fix the protective component 110 to the indoor unit 300, thereby securing the refrigerant hose assembly 100 to the indoor unit 300. Furthermore, the pipe cover 420 can cover the gap between the pipe clamp 410 and the refrigerant hose assembly 100, improving the appearance and enhancing the reliability of the fixation between the refrigerant hose assembly 100 and the indoor unit 300. The pipe cover 420 is screwed to the indoor unit 300, and the pipe clamp 410 is snapped into the indoor unit 300; and / or

[0095] The air conditioner's compressor is located in the indoor unit 300. This placement reduces the weight of the outdoor unit 200, facilitating its installation. Furthermore, since the outdoor unit 200 is typically mounted on a bracket, the reduced weight lowers the pressure on the bracket, preventing excessive stress and cracking, thus extending its lifespan. Additionally, the compressor's location in the indoor unit 300 generates significant noise during operation, potentially affecting user experience. Therefore, a noise reduction structure can be incorporated to absorb this noise, providing a comfortable and quiet environment. In one embodiment, the noise reduction structure may be sound-absorbing or sound-insulating cotton installed in the indoor unit 300; this is not a limitation.

[0096] The above description is merely an exemplary implementation of this application and does not limit the patent scope of the embodiments of this application. Any equivalent structural transformations made based on the technical concept of this application and the description and drawings of the embodiments of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the embodiments of this application.
