[0041] The present utility model provides an air conditioner, which includes an air conditioner outdoor unit and an air conditioner indoor unit 100. The flexible connection assembly 1 is respectively connected to the air conditioner indoor unit 100 and the air conditioner outdoor unit. The air conditioner can be a split air conditioner that is convenient for users to install personally. It uses a refrigerant pipe 11 to connect the indoor heat exchanger of the air conditioner indoor unit 100 and the outdoor heat exchanger of the air conditioner 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 / herself, only the air conditioner indoor unit 100 and the air conditioner outdoor unit need to be fixed respectively, without the need to assemble the refrigerant pipe 11 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 or an integrated air conditioner.
[0042] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the air conditioner includes:
[0043] An air conditioner indoor unit 100, an air conditioner outdoor unit, and a flexible connection assembly 1. The flexible connection assembly 1 is connected to the air conditioner indoor unit 100 and the air conditioner outdoor unit. The flexible connection assembly 1 includes a refrigerant pipe 11 and a drain pipe 12;
[0044] The air conditioner indoor unit 100 includes a casing 2. A first fixing position 21 is provided on the outer side of the casing 2. Part of the flexible connection assembly 1 passes through the casing 2, and the first pressing member 3 fixes the flexible connection assembly 1 to the casing 2 at the first fixing position 21. The drain pipe 12 is provided with a rigid structure at the first fixing position 21, and the rigid structure is used for radially supporting the drain pipe 12.
[0045] Specifically, the air conditioner includes an air conditioner outdoor unit and an air conditioner indoor unit 100. The flexible connection assembly 1 is respectively connected to the air conditioner indoor unit 100 and the air conditioner outdoor unit. The flexible connection assembly 1 includes a refrigerant pipe 11 and a drain pipe 12. There are two refrigerant pipes 11, and the two refrigerant pipes 11 are respectively an input refrigerant pipe 11 and an output refrigerant pipe 11. One ends of the refrigerant pipes 11 are respectively connected to the air conditioner indoor unit 100, and the other ends pass through the casing 2 of the air conditioner indoor unit 100 and are connected to the air conditioner outdoor unit. One end of the drain pipe 12 is connected to the air conditioner indoor unit 100, and the other end passes through the casing 2 of the air conditioner indoor unit 100, and can be connected to the air conditioner outdoor unit to cool the outdoor heat exchanger, or can be directly communicated with the outdoor space, so as to directly discharge the condensed water of the air conditioner indoor unit 100. After the refrigerant pipe 11 and the drain pipe 12 pass through the casing 2, if the refrigerant pipe 11 and the drain pipe 12 that have just passed through the casing 2 are not fixed, the refrigerant pipe 11 and the drain pipe 12 may swing left and right during the installation process, and there is a possibility of detaching from the air conditioner indoor unit 100 or affecting the installation of the internal components of the air conditioner indoor unit. Therefore, a fixing structure is often provided near the position where the refrigerant pipe 11 and the drain pipe 12 pass through the casing 2, so as to fix a section of the flexible connection assembly 1 passing through the casing 2 outside the casing 2.
[0046] Therefore, a first fixing position 21 is provided on the outer side of the casing 2, and the first pressing member 3 fixes the flexible connection assembly 1 to the casing 2 at the first fixing position 21. The first fixing position 21 is close to the passing position of the flexible connection assembly 1, and the first pressing member 3 directly presses and fixes the flexible connection assembly 1 to the outside of the casing 2, so as to facilitate the fixing of the flexible connection assembly 1. However, since the drain pipe 12 is generally configured as a flexible hose, there is a risk that the drain pipe 12 may be flattened during the pressing and fixing process of the first pressing member 3, resulting in blockage of the drain pipe 12 and affecting the discharge of the condensed water in the air conditioner indoor unit 100.
[0047] Therefore, the drain pipe 12 is provided with a rigid structure at the first fixing position 21, and the rigid structure is used for radially supporting the drain pipe 12. The rigid structure can provide a supporting effect for the radial direction of the drain pipe 12, so as to ensure that the first pressing member 3 presses the flexible connection assembly 1 at the first fixing position 21 and reduce the possibility of the drain pipe 12 being flattened.
[0048] In an embodiment of the present utility model, the rigid structure is configured to be a rigid pipe section of the drain pipe 12. That is, the drain pipe 12 includes two flexible pipe sections and a rigid pipe section. The two flexible pipe sections are respectively connected to opposite ends of the rigid pipe section and are respectively connected to the air conditioner indoor unit 100 and the air conditioner outdoor unit.
[0049] In another embodiment of the present utility model, the rigid structure is configured to be a rigid sleeve 13, and the rigid sleeve 13 is sleeved on the drain pipe 12. The rigid sleeve 13 is sleeved on the outside of the drain pipe 12, thereby defining a radial installation space for the drain pipe 12. This connection form facilitates the installation of the drain pipe 12. And the rigid sleeve 13 is only sleeved on a section of the drain pipe 12 at the first fixed position 21, so as to ensure the fixation of the drain pipe 12 and not affect the bending of the flexible connection assembly 1 during installation.
[0050] Wherein, the rigid sleeve 13 can be configured as a rigid metal pipe section, the rigid metal pipe section is sleeved on the drain pipe 12, and the inner diameter of the rigid metal pipe section is slightly larger than the outer diameter of the drain pipe 12.
[0051] In another embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the rigid sleeve 13 is configured as a metal spring. The metal spring can be axially bent, so that the rigid sleeve 13 can bend with the bending of the drain pipe 12, thereby facilitating the fixation of the flexible connection assembly 1. In other embodiments, the rigid sleeve 13 can also be configured as a metal bellows section.
[0052] In this embodiment, the refrigerant pipe 11 is configured as a metal bellows, and a braided wire mesh tube is sleeved on the outside of the bellows. Thereby, it can not only ensure the radial hardness of the refrigerant pipe 11, reduce the risk of the refrigerant pipe 11 being flattened, but also facilitate the bending of the refrigerant pipe 11, and can bear a certain pressure to reduce the possibility of accidental bursting of the refrigerant pipe 11. And a braided wire mesh tube is sleeved on its outside to further protect the metal bellows. And for the convenience of installing the refrigerant pipe 11, copper pipes are often provided at both ends of the metal bellows, and the metal bellows is welded and fixed to the copper pipes.
[0053] The technical solution of the present utility model is to set an air conditioner indoor unit 100 and an air conditioner outdoor unit, and a flexible connection assembly 1 connects the air conditioner indoor unit 100 and the air conditioner outdoor unit. The flexible connection assembly 1 includes a refrigerant pipe 11 and a drain pipe 12; the air conditioner indoor unit 100 includes a housing 2, and a first fixing position 21 is provided on the outer side of the housing 2. The flexible connection assembly 1 partially penetrates through the housing 2, and a first pressing member 3 fixes the flexible connection assembly 1 to the housing 2 at the first fixing position 21. The first pressing member 3 directly presses and fixes the flexible connection assembly 1 to the outside of the housing 2, thus facilitating the fixing of the flexible connection assembly 1. The drain pipe 12 is provided with a rigid structure at the first fixing position 21, and the rigid structure is used to radially support the drain pipe 12. This rigid structure can provide a supporting effect for the radial direction of the drain pipe 12, so that both the first pressing member 3 can press the flexible connection assembly 1 at the first fixing position 21 and the possibility of the drain pipe 12 being flattened can be reduced.
[0054] Please refer to Figure 1 and Figure 2 In the embodiment of the present utility model, the flexible connection assembly 1 further includes a sleeve 14. The housing 2 is provided with a first installation opening 22 for the refrigerant pipe 11 and the drain pipe 12 to penetrate through, and a second fixing position 23 is further provided on the outer side of the housing 2. The second fixing position 23 is arranged on the side of the first fixing position 21 close to the first installation opening 22;
[0055] The partial pipe sections of the refrigerant pipe 11 and the drain pipe 12 that penetrate through the first installation opening 22 are sequentially fixed to the second fixing position 23 and the first fixing position 21. The sleeve 14 is sleeved on the refrigerant pipe 11 and the drain pipe 12 and is located on the side of the second fixing position 23 away from the first installation opening 22.
[0056] Specifically, the flexible connection assembly 1 further includes a sleeve 14. The sleeve 14 is sleeved on the refrigerant pipe 11 and the drain pipe 12. The first pressing member 3 simultaneously presses the sleeve 14 and the refrigerant pipe 11 and the drain pipe 12 inside the sleeve 14, that is, the end of the sleeve 14 close to the air conditioner indoor unit is located before the first fixing position 21, so that the flexible connection assembly 1 forms an integral structure at the first fixing position 21, which can not only facilitate the fixing of the flexible connection assembly 1, but also reduce the possibility of the sleeve 14 axially slipping relative to the drain pipe 12 and the refrigerant pipe 11, and ensure the fixing effect of the flexible connection assembly 1.
[0057] The housing 2 is provided with a first installation opening 22 for the refrigerant pipe 11 and the drain pipe 12 to penetrate through, that is, the refrigerant pipe 11 and the drain pipe 12 jointly penetrate through the first installation opening 22. The first fixing position 21 and the second fixing position 23 are both arranged close to the first installation opening 22, so as to fix a section of the flexible connection assembly 1 close to the first installation opening 22, reduce the possibility of the flexible connection assembly 1 inside the air conditioner indoor unit 100 self-shifting during the installation of the air conditioner, and thus reduce the possibility of the flexible connection assembly 1 detaching from the air conditioner.
[0058] The second fixing position 23 is arranged on one side of the first fixing position 21 close to the first mounting opening 22. The pipe segments of the refrigerant pipe 11 and the drain pipe 12 passing through the first mounting opening 22 are sequentially fixed to the second fixing position 23 and the first fixing position 21, thereby increasing the mounting positions of the refrigerant pipe 11 and the drain pipe 12 on the housing 2 and improving the fixing stability of the flexible connection assembly 1.
[0059] At the second fixing position 23, the refrigerant pipe 11 and the drain pipe 12 are not sleeved with the sleeve 14, and the drain pipe 12 is not provided with a rigid structure. At this time, if the pressing and fixing form is adopted, it is not only inconvenient to fix the refrigerant pipe 11 and the drain pipe 12, but also there is a risk of flattening the drain pipe 12.
[0060] In view of this, in the embodiment of the present utility model, the second fixing position 23 is provided with a fixing block 4. The fixing block 4 is provided with a first fixing groove 41 and a second fixing groove 42. The refrigerant pipe 11 is clamped in the first fixing groove 41, and the drain pipe 12 is clamped in the second fixing groove 42. Specifically, the fixing block 4 is provided with the first fixing groove 41 and the second fixing groove 42, and the refrigerant pipe 11 is clamped in the first fixing groove 41, and the drain pipe 12 is clamped in the second fixing groove 42, so as to realize the separate fixing of the refrigerant pipe 11 and the drain pipe 12, which is not only convenient for fixing the refrigerant pipe 11 and the drain pipe 12, but also can reduce the possibility of flattening the drain pipe 12. The fixing block 4 is fixed to the outside of the housing 2. The fixing block 4 can be clamped to the housing 2, adhered to the housing 2, or fixedly connected to the housing 2 through fasteners.
[0061] Among them, the first fixing groove 41 and the second fixing groove 42 are often arranged on opposite sides of the fixing block 4, so as to improve the rationality of the arrangement of the drain pipe 12 and the refrigerant pipe 11 and reduce the cross-sectional area of the flexible connection assembly 1.
[0062] Since the two ends of the metal bellows are welded and fixed to the copper pipe, the two ends of the metal bellows may be deformed and expanded due to welding, resulting in difficulty for the refrigerant pipe 11 to be inserted into the first fixing groove 41. In the embodiment of the present utility model, please refer to Figures 4 to 6 , the first fixing groove 41 has a first opening side 43. The refrigerant pipe 11 is inserted into the first fixing groove 41 from the first opening side 43, and along the direction close to the first opening side 43, the width of the first fixing groove 41 becomes larger. That is, the first opening side 43 of the first fixing groove 41 is configured in an open form, so as to provide a certain degree of freedom for the installation of the refrigerant pipe 11 and reduce the possibility of difficult installation due to deformation of the refrigerant pipe 11. At this time, in order to reduce the possibility of the refrigerant pipe 11 coming out, the first fixing groove 41 is arranged on the side of the fixing block 4 facing the housing 2, and the first opening side 43 faces the housing 2.
[0063] Since the drain pipe 12 is configured as a flexible hose, in order to reduce the possibility of the drain pipe 12 coming out of the second fixing groove 42, in an embodiment of the present invention, the second fixing groove 42 has a second opening side 44, and the drain pipe 12 is snapped into the second fixing groove 42 from the second opening side 44, and the width of the second opening side 44 is less than or equal to the diameter of the drain pipe 12. Specifically, the width of the second opening side 44 is less than or equal to the diameter of the drain pipe 12, so that the edge of the second opening side 44 can further prevent the drain pipe 12 from coming out. And as can be seen from the drawings, the second opening side 44 is formed by providing an installation notch on one side of the second fixing groove 42.
[0064] Further, please refer to Figure 3 , a buffer member 26 is provided on one side of the second fixing position 23 facing the fixing block 4. The buffer member 26 abuts between the fixing block 4 and the housing 2, so as to provide a buffering effect for the fixing block 4 and prevent the refrigerant pipe 11 from directly contacting the housing 2. Among them, the buffer member 26 can be configured as a sponge sheet or a rubber sheet, etc., and the buffer member 26 is directly adhered to the outside of the housing 2.
[0065] For the convenience of fixing the fixing block 4, in an embodiment of the present invention, a second pressing member 5 is further provided at the second fixing position 23, and the second pressing member 5 presses the fixing block 4 at the second fixing position 23 to fix the drain pipe 12 and the refrigerant pipe 11. Specifically, the fixing block 4 is pressed and fixed to the outside of the housing 2 through the second pressing member 5, so as to facilitate the installation of the fixing block 4 and the housing 2.
[0066] Further, in order to reduce the possibility of the fixing block 4 moving relative to the second pressing member 5 by itself, in an embodiment of the present invention, a limiting groove 45 is provided on the side of the fixing block 4 facing away from the housing 2, and the second pressing member 5 is snapped into the limiting groove 45. Specifically, a limiting groove 45 is provided on the side of the fixing block 4 facing away from the housing 2, and the second pressing member 5 is snapped into the limiting groove 45, so as to provide a block for the fixing block 4 to come out relative to the second pressing member 5 and reduce the possibility of the fixing at the second fixing position 23 failing during use.
[0067] For the convenience of machining the housing 2, the housing 2 includes two main housing parts and an installation housing part that are spliced together. The first fixing position 21 and the second fixing position 23 are both provided on the installation housing part, so that the main housing part and the installation housing part are processed separately and then spliced together again, thus facilitating the machining of the housing 2.
[0068] Please refer to Figures 1 to 5 , in an embodiment of the present invention, the first fixing position 21 is provided with two first mounting seats 24 arranged at intervals, the first pressing member 3 is configured as a first pressing hoop, and both ends of the first pressing hoop are respectively installed on the two first mounting seats 24;
[0069] The second fixing position 23 is provided with two second mounting seats 25 arranged at intervals. The second pressing member 5 is configured as a second pressing hoop, and both ends of the second pressing hoop are respectively mounted on the two second mounting seats 25.
[0070] Specifically, the first fixing position 21 has two first mounting seats 24 arranged at intervals. The two first mounting seats 24 are respectively arranged on opposite sides of the flexible connection assembly 1. One end of the first pressing member 3 is mounted on one of the two first mounting seats 24, and the other end bypasses the flexible connection assembly 1 and is mounted on the other first mounting seat 24; thereby pressing the flexible connection assembly 1 against the first fixing position 21, so as to avoid directly mounting the first pressing member 3 on the casing 2 and reduce the installation difficulty of the first pressing member 3. The first mounting seat 24 can be adhesively bonded, snap-fitted or fixedly connected to the casing 2 through fasteners; or the first mounting seat 24 is integrally formed with the casing 2. And the first pressing member 3 is configured as a first pressing hoop, and the shape of the first pressing hoop should be adapted to the shape of the flexible connection assembly 1, so as to not only fix the flexible connection assembly 1, but also not generate too much squeezing force on the flexible connection assembly 1. In other embodiments, the first pressing member 3 can also be configured as a tie strap, and after the tie strap tightens the flexible connection assembly 1, it is fixed to the first mounting seat 24.
[0071] The second fixing position 23 has two second mounting seats 25 arranged at intervals. The two second mounting seats 25 are respectively arranged on opposite sides of the flexible connection assembly 1. One end of the second pressing member 5 is mounted on one of the two second mounting seats 25, and the other end bypasses the flexible connection assembly 1 and is mounted on the other second mounting seat 25; thereby pressing the flexible connection assembly 1 against the second fixing position 23, so as to avoid directly mounting the second pressing member 5 on the casing 2 and reduce the installation difficulty of the second pressing member 5. The second mounting seat 25 can be adhesively bonded, snap-fitted or fixedly connected to the casing 2 through fasteners; or the second mounting seat 25 is integrally formed with the casing 2. And the second pressing member 5 is configured as a second pressing hoop, and the shape of the second pressing hoop should be adapted to the shape of the fixing block 4, so as to not only fix the flexible connection assembly 1, but also not generate too much squeezing force on the flexible connection assembly 1. In other embodiments, the second pressing member 5 can also be configured as a tie strap, and after the tie strap tightens the fixing block 4, it is fixed to the second mounting seat 25.
[0072] To facilitate the installation of the first pressing member 3, in the embodiment of the present invention, the first mounting seat 24 is provided with a first pre-installation structure, and the first pressing hoop and the first mounting seat 24 are fixed by a first fastener.

Therefore, the extending directions of the upper and lower sides of the first mounting base 24, that is, along the up and down directions of the air conditioner indoor unit 100. In other embodiments, the first pressing hoop and the first mounting base 24 can also be fixed only by the first fastener, or the first pressing hoop and the first mounting base 24 can be fixed only by clamping or bonding.
[0075] For the convenience of installing the first pressing member 3, in the embodiment of the present invention, the second mounting base 25 is provided with a second pre-mounting structure, and the second pressing hoop and the second mounting base 25 are fixed by a second fastener. Specifically, the second pre-mounting structure can realize the preliminary fixation of the second pressing hoop and the second mounting base 25, so that when the subsequent operator fixes the second pressing hoop and the second mounting base 25 by the second fastener, there is no need to additionally fix the second pressing hoop, thus facilitating the installation of the second pressing hoop.
[0076] Further, the second mounting structure includes two second clamping portions 251 respectively disposed on the upper and lower sides of the second mounting base 25, and the two second clamping portions 251 are respectively clamped to the upper and lower sides of the second pressing hoop. Specifically, the two second clamping portions 251 are respectively disposed on the upper and lower sides of the second pressing hoop, so as to ensure the stability of the pre-fixation of the second pressing hoop, and the second clamping portion 251 is directly clamped to the edge of the second pressing hoop, so that there is no need to correspondingly provide a clamping portion on the second pressing hoop, thus facilitating the installation of the second pressing hoop.
[0077] Wherein, the extending directions of the upper and lower sides of the second mounting base 25, that is, along the axial direction of the flexible connection assembly 1, and the first mounting port 22 is usually mounted at the lower end of the casing 2, and the flexible connection assembly 1 extends upward to the casing 2. Therefore, the extending directions of the upper and lower sides of the second mounting base 25, that is, along the up and down directions of the air conditioner indoor unit 100. In other embodiments, the second pressing hoop and the second mounting base 25 can also be fixed only by the second fastener, or the second pressing hoop and the second mounting base 25 can be fixed only by clamping or bonding.
[0078] Please refer to againFigures 1 to 5 In an embodiment of the present utility model, the flexible connection assembly 1 further includes a power-on wire 15. The machine shell 2 is further provided with a second installation opening 27, which is arranged between the first fixing position 21 and the second fixing position 23. The power-on wire 15 passes through the second installation opening 27 and is sleeved in the sleeve 14, and the power-on wire 15, the refrigerant pipe 11 and the drain pipe 12 are commonly fixed at the first fixing position 21.
[0079] Specifically, the flexible connection assembly 1 often further includes a power-on wire 15. The refrigerant pipe 11, the drain pipe 12 and the power-on wire 15 are commonly sleeved in the sleeve 14, which facilitates the installation of the indoor unit 100 of the air conditioner and the outdoor unit of the air conditioner. However, at the second fixing position 23, only a first fixing groove 41 and a second fixing groove 42 are provided on the second fixing position 23, and the channel wire and the drain pipe 12 are commonly fixed in the second fixing groove 42. At this time, the power-on wire 15 may exert a squeezing effect on the drain pipe 12, affecting the flow rate of the drain pipe 12. Therefore, in order to reduce the possibility of the drain pipe 12 being squeezed, the machine shell 2 is further provided with a second installation opening 27, which is arranged between the first fixing position 21 and the second fixing position 23. The power-on conductor passes through the second installation opening 27 and then is sleeved in the sleeve 14, so as to avoid fixing the power-on wire 15 at the second fixing position 23, and the power-on wire 15, the refrigerant pipe 11, the drain pipe 12 and the sleeve 14 are commonly fixed at the second fixing position 23, thereby improving the structural integrity of the flexible connection assembly 1.
[0080] To facilitate the power-on wire 15 to pass through the second installation opening 27, in an embodiment of the present utility model, the second installation opening 27 communicates with the first installation opening 22, and a wire gathering portion 271 protruding inwards is provided on the side of the second installation opening 27 facing the first installation opening 22. The wire gathering portion 271 is used to limit the power-on wire 15. Specifically, since the first installation opening 22 is used for the drain pipe 12 and the refrigerant pipe 11 to pass through, and the second installation opening 27 is only used for the power-on wire 15 to pass through, the area of the first installation opening 22 is necessarily larger than the area of the second installation opening 27, resulting in a smaller area of the second installation opening 27 and a greater difficulty in passing the power-on wire 15. Therefore, the second installation opening 27 communicates with the first installation opening 22, so that the power-on wire 15 can first pass through the first installation opening 22 and then be fixed at the second installation opening 27, thus facilitating the power-on wire 15 to pass through the second installation opening 27. And in order to reduce the possibility of the power-on wire 15 slipping out of the second installation opening 27, a wire gathering portion 271 protruding inwards is provided on the side of the second installation opening 27 facing the first installation opening 22, so as to limit the power-on wire 15. And the second installation opening 27 is configured as an installation notch arranged at the first installation opening 22 and extending towards the first fixing position 21, which facilitates the processing of the first installation opening 22 and the second installation opening 27.
