[0040] In existing air conditioners, the connecting pipe assembly includes a circuit, a refrigerant pipe, and a drain pipe, which are used to connect the indoor unit and the outdoor unit to achieve the transmission of electric energy and refrigerant. The strength of the refrigerant pipe and the drain pipe is weak, and it is easy to crack when subjected to external force trampling, which may lead to refrigerant leakage or water leakage.

[0041] In view of this, the embodiments of the present utility model provide a refrigerant hose assembly and an air conditioner. By providing a pressure-resistant flexible member, it can prevent pressure in the radial direction, increase the structural strength of the drain pipe or the refrigerant hose, improve the pressure resistance of the drain pipe or the 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 the refrigerant hose, and further enhance the safety of using the refrigerant hose assembly.

[0042] To better understand the above technical solutions, the following will describe the above technical solutions in detail with reference to the accompanying drawings.

[0043] As Figure 1 shown, the embodiments of the present utility model propose a refrigerant hose assembly 100, and the refrigerant hose assembly 100 includes:

[0044] A protection member 110, a protection cavity is formed inside the protection member 110, and the material of the protection member 110 can be the same as the outer sleeve part of the existing circular hose, such as rubber material. Optionally, the protection member 110 can be a flat rubber sleeve, and the flat rubber sleeve has a relatively flatter shape compared to other dimensions. The air conditioner using the refrigerant hose assembly 100 has mobility, and compared with the existing circular hose, the flat rubber sleeve can reduce the gap when closing the window and improve the appearance. Of course, the protection member 110 can also be plastic, pearl cotton, heat shrinkable tube, etc., which is not limited herein;

[0045] A refrigerant hose 120, which is arranged in the protection cavity. The refrigerant hose 120 can be applied to a split-type outdoor unit 200 and an indoor unit 300 to form a refrigerant circuit. The refrigerant hose 120 is a hose with flexibility, so the air conditioner using the refrigerant hose 120 has mobility;

[0046] A drain pipe 130, which is arranged in the protection cavity. The refrigerant hose 120 and the drain pipe 130 are arranged side by side. The drain pipe 130 is connected between the indoor unit 300 and a building drainage system. In addition, the drain pipe 130 can be a flexible pipe for easy installation; and

[0047] A pressure-resistant flexible member 140, at least one of the refrigerant hose 120 and the drain pipe 130 is sleeved with a pressure-resistant flexible member 140. The pressure-resistant flexible member 140 prevents pressure in the radial direction and has bendable flexibility in the length direction.

[0048] In the technical solution adopted in this embodiment, through the provided pressure-resistant flexible member 140, radial pressure resistance can be achieved, increasing the structural strength of the drain pipe 130 or the refrigerant hose 120, improving the pressure resistance of the drain pipe 130 or the refrigerant hose 120, preventing the drain pipe 130 from cracking and leaking water or the refrigerant hose 120 from cracking and leaking refrigerant, extending the service life of the drain pipe 130 or the refrigerant hose 120, and further enhancing the safety of the refrigerant hose assembly 100 during use. Moreover, the pressure-resistant flexible member 140 has bendable flexibility in the length direction and can bend along with the refrigerant hose 120, improving the convenience of installation.

[0049] In one embodiment, the pressure-resistant flexible member 140 can be sleeved outside the drain pipe 130, or outside the refrigerant hose 120, or simultaneously outside both the drain pipe 130 and the refrigerant hose 120. In this way, since the pressure-resistant flexible member 140 has a certain rigidity in the radial direction to resist pressure, the structural strength of the pipeline is increased, the pressure resistance of the pipeline is greatly enhanced, it can withstand greater external force trampling or collision, reducing the risk of pipeline cracking and preventing the leakage of refrigerant or water in the pipeline, effectively improving the safety of the refrigerant hose assembly 100 during use.

[0050] As an alternative, the pressure-resistant flexible member 140 can be a metal spring or a metal bellows. Both the metal spring and the metal bellows are spiral-shaped, can be bent but not extremely bent, can deform and bend synchronously with the internal refrigerant hose 120 or drain pipe 130, and will not be violently damaged by users. Additionally, since the materials of the metal spring 141 or the metal bellows 143 are both metals, they have a certain rigidity in the radial direction and a good pressure-resistant effect, and the drain pipe 130 or the refrigerant hose 120 will not crack or be crushed when subjected to external pressure. In one embodiment, the material of the metal spring 141 or the metal bellows 143 is SUS304 stainless steel, which has elasticity, flexibility, pressure resistance, corrosion resistance, and good thermal conductivity, enabling the pressure-resistant flexible member 140 to adapt to changes such as thermal expansion and contraction or mechanical vibration in the pipeline system and maintaining the integrity and stability of the pipeline in a high-pressure environment.

[0051] In an embodiment of the present utility model, referring to Figure 2, the pressure - resistant flexible member 140 includes a metal spring 141 sleeved outside the drain pipe 130. The drain pipe 130 has the function of draining water and is usually a flexible pipe. When it is squeezed or collided, it is easily flattened or cracked, thus affecting normal drainage. For this reason, in this embodiment, the pressure - resistant flexible member 140 includes a metal spring 141. The metal spring 141 is sleeved outside the drain pipe 130 and can partially or completely cover the drain pipe 130. It is equivalent to adding a layer of compressive structure outside the drain pipe 130. By means of the radial stiffness of the metal spring 141, the strength of the drain pipe 130 is improved, the pressure resistance of the drain pipe 130 is enhanced, the drain pipe 130 is prevented from being flattened or cracked when stressed, and the normal drainage of the drain pipe 130 is ensured.

[0052] In an embodiment of the present utility model, referring to Figure 2 , the end of the metal spring 141 is fixed to the drain pipe 130 through a tape 142. In this way, the metal spring 141 and the drain pipe 130 can be fixed into a whole, preventing the metal spring 141 from moving axially along the drain pipe 130 and affecting the compressive effect. As an alternative, the tape 142 can be an ordinary tape 142 or a strong tape 142, which is not limited herein.

[0053] In an embodiment of the present utility model, referring to Figure 2 , the pressure - resistant flexible member 140 includes a metal bellows 143 sleeved outside the refrigerant hose 120. Optionally, the metal bellows 143 is sleeved outside the thick hose 121, so as to improve the strength of the thick hose 121 and prevent it from being flattened or cracked.

[0054] In an embodiment of the present utility model, referring to Figure 2 , the refrigerant hose 120 includes a thick hose 121 and a thin hose 122 arranged side by side, and the diameter of the thin hose 122 is smaller than that of the thick hose 121. The pressure - resistant flexible member 140 is arranged outside the thick hose 121. During the formation of the loop of the refrigerant hose 120, there will be a hot loop and a cold loop. One of the thin hose 122 and the thick hose 121 serves as the hot loop, and the other of the thin hose 122 and the thick hose 121 serves as the cold loop. Since the diameter of the thick hose 121 is the largest, when the entire refrigerant hose assembly 100 is under pressure, the thick hose 121 will be pressured first. For this reason, a pressure - resistant flexible member 140 is arranged outside the thick hose 121 to effectively improve the pressure - resistant ability of the thick hose 121.

[0055] In an embodiment of the present utility model, referring to Figure 1 and Figure 4, the refrigerant hose assembly is applied to an air conditioner, which includes an outdoor unit 200 having an installation opening. The refrigerant hose assembly 100 further includes a hole-sealing assembly 150 disposed outside one end of the protective member 110 and sealingly connected to the installation opening. In the existing air conditioner, the outdoor unit 200 usually has an installation opening, and the refrigerant hose assembly 100 directly passes through the installation opening to connect with the outdoor unit 200. There is a relatively large gap between the refrigerant hose assembly 100 and the installation opening, and dust, mosquitoes, mice, etc. may enter the air conditioner through the above gap, increasing the cleaning difficulty. Therefore, in this embodiment, a hole-sealing assembly 150 is provided. The hole-sealing assembly 150 is sleeved outside one end of the protective member 110, and the protective member 110 and the installation opening are connected through the hole-sealing assembly 150, effectively reducing the gap between the protective member 110 and the installation opening, improving the sealing effect between the protective member 110 and the installation opening, preventing dust, mosquitoes, mice, etc. from entering the air conditioner, and ensuring the normal operation of the air conditioner.

[0056] In an embodiment of the present invention, referring to Figure 3 , the hole-sealing assembly 150 includes:

[0057] A flexible telescopic sleeve 151, one end of which is sleeved outside the protective member 110 and the other end is sealingly connected to the installation opening; and

[0058] A locking member 152 connecting the flexible telescopic sleeve 151 and the protective member 110 to fix the flexible telescopic sleeve 151 to the protective member 110.

[0059] Specifically, the hole-sealing assembly 150 includes a flexible telescopic sleeve 151 and a locking member 152. Among them, the flexible telescopic sleeve 151 can be telescoped and bent in the length direction and deformed in the radial direction, which can make up for the gap between the protective member 110 and the installation opening and improve the sealing effect. Moreover, the flexible telescopic sleeve 151 can twist or bend synchronously with the protective member 110, so that the gap between the protective member 110 and the installation opening will not increase, thereby further ensuring the sealing effect. The locking member 152 is used to fix the flexible telescopic sleeve 151 and the protective member 110. It can be understood that the flexible telescopic sleeve 151 is fixed outside the protective member 110 through the locking member 152. Compared with the method of directly setting sealing members such as sealing rings on the periphery of the installation opening, the flexible telescopic sleeve 151 in this solution is fixed outside the protective member 110 through the locking member 152, which can not only ensure the sealing effect but also ensure the installation stability.

[0060] To facilitate the bending of the flexible telescopic sleeve 151 as the protective member 110 twists and ensure the connection stability of the hole-sealing assembly 150, in one embodiment, the flexible telescopic sleeve 151 is configured as a corrugated pipe. The corrugated pipe has a plurality of connecting segments that bend and protrude outward, that is, the cross-section of the corrugated pipe along its axial direction is generally configured in a wave shape, so that the flexible telescopic sleeve 151 can better adapt to the twisting or bending of the protective member 110, thereby ensuring the connection stability of the hole-sealing assembly 150. In other embodiments, the flexible telescopic sleeve 151 can also be configured as a snake-shaped pipe formed by helically winding strip structures.

[0061] In one embodiment of the present utility model, referring to Figure 5 , 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 cooperated to be fixed so as to cover and fix the protective member 110. In this way, the installation of the locking member 152 can be carried out. It can be understood that during assembly, first, the flexible telescopic sleeve 151 is sleeved on the outside of the protective member 110, and then the first covering portion 1521 and the second covering portion 1522 are respectively wrapped on the outside of the flexible telescopic sleeve 151, and the first covering portion 1521 and the second covering portion 1522 are locked, so that the flexible telescopic sleeve 151 is tightly sleeved on the outside of the protective member 110. As an alternative, 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 structure, which is not limited herein.

[0062] In one embodiment of the present utility model, referring to Figure 2 , 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 protection cavity at least includes a first sub-cavity 111 and a second sub-cavity 112 that are separated from each other. The thick hose 121 is arranged in the first sub-cavity 111, and the thin hose 122 and the drain pipe 130 are arranged in the second sub-cavity 112. During the formation of the refrigerant hose 120 into a circuit, there will be 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. In order to prevent interference, by arranging a partition plate in the protection cavity, the protection cavity can be separated into a first sub-cavity 111 and a second sub-cavity 112, which can play a role in separating heat sources. The spaces of the first sub-cavity 111 and the second sub-cavity 112 are the same, and the thin hose 122 or the thick hose 121 passes through respectively, so that it can be made flat instead of circular. After closing the window, the gap will be very small. The thin hose 122 and the drain pipe 130 are in the second sub-cavity 112, which is convenient for installation.

[0063] In one embodiment, the thick refrigerant hose 121 includes a first metal inner tube, a first elastic protective layer located on the outer surface of the first metal inner tube, and a first metal braided layer provided on the outer surface of the first elastic protective layer; and / or, the thin refrigerant hose 122 includes a second metal inner tube, a second elastic protective layer located on the outer surface of the second metal inner tube, and a second metal braided layer provided on the outer surface of the second elastic protective layer. In this way, the refrigerant hose 120 can be bent arbitrarily, but has a minimum bending angle, which can not only meet the mobility of the mobile air conditioner, allowing the outdoor unit to be moved freely, but also prevent the refrigerant hose 120 from being damaged and leaking.

[0064] In one embodiment of the present utility model, referring to Figures 1 to 3 , the refrigerant hose assembly 100 further includes a heat insulation member 160, and the heat insulation member 160 is provided outside the protection member 110. In a high humidity situation, condensed water may appear on the outside of the refrigerant hose assembly 100. For this reason, the heat insulation member 160 is provided outside the protection member 110. By providing the heat insulation member 160, the thermal resistance between the inside of the protection member 110 and the external environment can be increased, effectively reducing heat transfer and preventing condensed water from appearing on the outside of the protection member 110.

[0065] In one embodiment of the present utility model, the material of the heat insulation member 160 is configured as any one of heat insulation cotton, polyethylene, polyurethane, and ethylene propylene diene monomer rubber. The above materials all have good heat insulation effects and can effectively prevent the appearance of condensed water.

[0066] To achieve the above object, an embodiment of the present utility model proposes an air conditioner, referring to Figure 4 , the air conditioner includes an indoor unit 300, an outdoor unit 200, and the refrigerant hose assembly 100 described above. The refrigerant hose assembly 100 connects the outdoor unit 200 and the indoor unit 300. Specifically, for the specific structure of the refrigerant hose assembly 100, refer to the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0067] It should be noted that the air conditioner of the present utility model can be a split air conditioner that is convenient for users to install personally. 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 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 300 and the outdoor unit 200 respectively, without the need to assemble the refrigerant pipe and add refrigerant, thereby 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 utility model can also be a common split air conditioner.

[0068] In one embodiment of the present utility model, referring toFigure 3 and Figure 4 The outdoor unit 200 has a mounting opening, and a mounting member 220 is provided at the mounting opening. The mounting member 220 is provided with a through hole communicating with the mounting opening, and the hole-sealing assembly 150 is hermetically connected to the through hole. In this way, the hole-sealing assembly 150 can be fixed by the mounting member 220, and on the basis of ensuring the sealing effect, the mounting stability is improved; and / or

[0069] Referring to Figure 5 The air conditioner further includes a pipe clamp 410 and a pipe cover 420. The pipe clamp 410 fixes the other end of the protection member 110 to the indoor unit 300. The pipe cover 420 is connected to the indoor unit 300 and covers the pipe clamp 410 and the other end of the protection member 110. In this way, the protection member 110 can be clamped and fixed to the indoor unit 300 by the pipe clamp 410, realizing the fixation of the refrigerant hose assembly 100 and the indoor unit 300. Moreover, the pipe cover 420 can cover the gap between the pipe clamp 410 and the refrigerant hose assembly 100, improving the appearance, and at the same time enhancing the fixing reliability of the refrigerant hose assembly 100 and the indoor unit 300. Optionally, the pipe cover 420 and the indoor unit 300 are screwed, and the pipe clamp 410 and the indoor unit 300 are clamped; and / or

[0070] The compressor of the air conditioner is arranged in the indoor unit 300. In this way, the compressor is arranged in the indoor unit 300, which can reduce the weight of the outdoor unit 200, thus facilitating the installation of the outdoor unit 200. At the same time, since the outdoor unit 200 usually needs to be fixed on a bracket, the reduction of the weight of the outdoor unit 200 can reduce the pressure on the bracket, prevent the bracket from being subjected to excessive pressure and generating a cracking risk, and further improve the service life of the bracket. In addition, when the compressor is arranged in the indoor unit 300, 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 provided. 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 use 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 300, which is not limited herein.

[0071] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the embodiments of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the description and drawings of the embodiments of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the embodiments of the present invention.
