[0051] The present application proposes an air conditioner, the air conditioner comprises an outdoor unit and an indoor unit 1000. A flexible connection assembly 1 is connected to the indoor unit 1000 and the outdoor unit. The air conditioner may be a split-type air conditioner that is convenient for users to install personally. A refrigerant pipe 11 is used to connect the indoor heat exchanger of the indoor unit 1000 and the outdoor heat exchanger of the outdoor unit, and the refrigerant is injected into the refrigerant circulation loop before the air conditioner leaves the factory. In this way, when the user installs the air conditioner by himself, he only needs to fix the indoor unit 1000 and the outdoor unit respectively, without assembling the refrigerant pipe 11 and filling the refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user. However, the design is not limited to this. In an embodiment, the air conditioner of the present application may also be an ordinary split-type air conditioner or an integrated air conditioner.

[0052] As shown in FIG. 1 to FIG. 5, in an embodiment of the present application, the air conditioner comprises: an indoor unit 1000, an outdoor unit, and a flexible connection assembly 1. The flexible connection assembly 1 is connected to the indoor unit 1000 and the outdoor unit, and the flexible connection assembly 1 comprises a refrigerant pipe 11 and a drain pipe 12; the indoor unit 1000 comprises a casing 2, a first fixing position 21 is provided at the outer side of the casing 2, a part of the flexible connection assembly 1 passes through the casing 2, a first pressing member 3 is configured to fix the flexible connection assembly 1 to the casing 2 at the first fixing position 21, a rigid structure is provided at the drain pipe 12 at the first fixing position 21, and the rigid structure is configured to radially support the drain pipe 12.

[0053] In an embodiment, the air conditioner comprises an outdoor unit and an indoor unit 1000. The flexible connection assembly 1 is connected to the indoor unit 1000 and the outdoor unit. The flexible connection assembly 1 comprises a refrigerant pipe 11 and a drain pipe 12. There are two refrigerant pipes 11, one of the two refrigerant pipes 11 is an input refrigerant pipe 11 and another of the two refrigerant pipes 11 is an output refrigerant pipe 11. One end of the refrigerant pipe 11 is connected to the indoor unit 1000, and another end of the refrigerant pipe 11 passes through the casing 2 of the indoor unit 1000 to connect to the outdoor unit. One end of the drain pipe 12 is connected to the indoor unit 1000, and another end of the drain pipe 12 passes through the casing 2 of the indoor unit 1000. The drain pipe 12 can be connected to the outdoor unit to cool the outdoor heat exchanger, or directly communicated with the outdoor space to directly discharge the condensed water of the indoor unit 1000. 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, which may cause them to detach from the indoor unit 1000 or affect the installation of internal components of the indoor unit. Therefore, a fixation 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 the section of the flexible connection assembly 1 passing through the casing 2 to the outside of the casing 2.

[0054] Therefore, a first fixing position 21 is provided at the outer side of the casing 2, and a 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 adjacent 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 on the casing 2, thereby facilitating the fixing of the flexible connection assembly 1. However, since the drain pipe 12 is generally configured as a flexible hose, during the pressing and fixing process of the first pressing member 3, the drain pipe 12 is at risk of being flattened, leading to blockage of the drain pipe 12 and affecting the discharge of condensed water in the indoor unit 1000.

[0055] Therefore, a rigid structure is provided at the drain pipe 12 at the first fixing position 21, and the rigid structure is configured to radially support the drain pipe 12. The rigid structure can provide radial support for the drain pipe 12, thereby not only ensuring that the first pressing member 3 presses the flexible connection assembly 1 against the first fixing position 21, but also reducing the possibility of the drain pipe 12 being flattened.

[0056] In the embodiment of the present application, the rigid structure is configured as a section of rigid pipe provided at the drain pipe 12, that is, the drain pipe 12 comprises two flexible pipe sections and one rigid pipe section. The two flexible pipe sections are respectively connected to the opposite ends of the rigid pipe section, and the two flexible pipe sections are respectively connected to the indoor unit 1000 and the outdoor unit.

[0057] In an embodiment of the present application, the rigid structure is configured as a rigid sleeve 13, and the rigid sleeve 13 is sleeved on the drain pipe 12. The rigid sleeve 13 is sleeved on the drain pipe 12, thereby defining the radial mounting space of the drain pipe 12. This connection form facilitates the mounting of the drain pipe 12. Moreover, the rigid sleeve 13 is only sleeved on a section of the drain pipe 12 at the first fixing position 21, so that the fixing of the drain pipe 12 can be ensured without affecting the bending of the flexible connection assembly 1 during mounting.

[0058] The rigid sleeve 13 may be configured as a rigid metal pipe section, the rigid sleeve 13 is sleeved on the drain pipe 12, and the inner diameter of the rigid metal pipe section is slightly greater than the outer diameter of the drain pipe 12.

[0059] In an embodiment of the present application, as shown in FIG. 1 and FIG. 2, the rigid sleeve 13 is configured as a metal spring. The metal spring can be bent axially, so that the rigid sleeve 13 can be bent along with the bending of the drain pipe 12, thereby facilitating the fixing of the flexible connection assembly 1. In an embodiment, the rigid sleeve 13 may also be configured as a metal corrugated pipe section.

[0060] In the embodiment, the refrigerant pipe 11 is configured as a metal corrugated pipe, and a braided mesh pipe is sleeved on the metal corrugated pipe. This 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 burst of the refrigerant pipe 11. In addition, the braided mesh pipe sleeved on the metal corrugated pipe further protects the metal corrugated pipe. To facilitate the mounting of the refrigerant pipe 11, copper pipes are often provided at both ends of the metal corrugated pipe, and the metal corrugated pipe is fixed to the copper pipes by welding.

[0061] The technical solution of the present application is provided with an indoor unit 1000 and an outdoor unit, the flexible connection assembly 1 is connected to the indoor unit 1000 and the outdoor unit, and the flexible connection assembly 1 comprises a refrigerant pipe 11 and a drain pipe 12. The indoor unit 1000 comprises a casing 2, a first fixing position 21 is provided at the outer side of the casing 2, a part of the flexible connection assembly 1 passes through the casing 2, and a first pressing member 3 fixes the flexible connection assembly 1 to the casing 2 at the first fixing position 21. The first pressing member 3 directly presses and fixes the flexible connection assembly 1 to the on the casing 2, thereby facilitating the fixing of the flexible connection assembly 1. A rigid structure is provided at the drain pipe 12 at the first fixing position 21, and the rigid structure is configured to radially support the drain pipe 12. The rigid structure can provide radial support for the drain pipe 12, thereby not only ensuring that the first pressing member 3 presses the flexible connection assembly 1 against the first fixing position 21, but also reducing the possibility of the drain pipe 12 being flattened.

[0062] As shown in FIG. 1 and FIG. 2, in the embodiment of the present application, the flexible connection assembly 1 further comprises a sleeve 14, the casing 2 is provided with a first installation port 22, the first installation port 22 allows the refrigerant pipe 11 and the drain pipe 12 to pass through, a second fixing position 23 is further provided at the outer side of the casing 2, and the second fixing position 23 is provided at a side of the first fixing position 21 adjacent to the first installation port 22; the parts of the refrigerant pipe 11 and the drain pipe 12 that pass through the first installation port 22 are sequentially fixed to the second fixing position 23 and the first fixing position 21, and the sleeve 14 is sleeved on the refrigerant pipe 11 and the drain pipe 12 and provided at a side of the second fixing position 23 away from the first installation port 22.

[0063] In an embodiment, the flexible connection assembly 1 further comprises 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, one end of the sleeve 14 adjacent to the indoor unit 1000 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, thereby not only facilitating the fixing of the flexible connection assembly 1, but also reducing the possibility of axial sliding of the sleeve 14 relative to the drain pipe 12 and the refrigerant pipe 11, and ensuring the fixing effect of the flexible connection assembly 1.

[0064] The casing 2 is provided with a first installation port 22, the first installation port 22 allows the refrigerant pipe 11 and the drain pipe 12 to pass through. That is, the refrigerant pipe 11 and the drain pipe 12 pass through the first installation port 22 together. The first fixing position 21 and the second fixing position 23 are provided adjacent to the first installation port 22, so as to fix the section of the flexible connection assembly 1 adjacent to the first installation port 22, so as to reduce the possibility of self-displacement of the flexible connection assembly 1 inside the indoor unit 1000 along with the mounting of the air conditioner, thereby reducing the possibility of the flexible connection assembly 1 detaching from the air conditioner.

[0065] The second fixing position 23 is provided at a side of the first fixing position 21 adjacent to the first installation port 22, and the parts of the refrigerant pipe 11 and the drain pipe 12 that pass through the first installation port 22 are sequentially fixed to the second fixing position 23 and the first fixing position 21, thereby increasing the installation positions of the refrigerant pipe 11 and the drain pipe 12 with the casing 2 and improving the connection stability of the flexible connection assembly 1.

[0066] Since the sleeve 14 is not sleeved on the refrigerant pipe 11 and the drain pipe 12 at the second fixing position 23, and the rigid structure is not provided at the drain pipe 12, if the pressing and fixing form is adopted at this time, 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.

[0067] In view of this, in the embodiment of the present application, a fixation block 4 is provided at the second fixing position 23, the fixation block 4 is provided with a first fixation groove 41 and a second fixation groove 42, the refrigerant pipe 11 is clamped in the first fixation groove 41, and the drain pipe 12 is clamped in the second fixation groove 42. In an embodiment, the fixation block 4 is provided with a first fixation groove 41 and a second fixation groove 42, and the refrigerant pipe 11 is clamped in the first fixation groove 41, and the drain pipe 12 is clamped in the second fixation groove 42, thereby realizing the fixing of the refrigerant pipe 11 and the drain pipe 12, which not only facilitates the fixing of the refrigerant pipe 11 and the drain pipe 12, but also reduces the possibility of flattening the drain pipe 12. The fixation block 4 is fixed to the on the casing 2, and the fixation block 4 can be clamped to the casing 2, bonded to the casing 2, or connected to the casing 2 through fasteners.

[0068] The first fixation groove 41 and the second fixation groove 42 are respectively provided at opposite sides of the fixation block 4, thereby improving the rationality of the arrangement of the drain pipe 12 and the refrigerant pipe 11 and reducing the cross-sectional area of the flexible connection assembly 1.

[0069] Since both ends of the metal corrugated pipe are fixed to the copper pipes by welding, both ends of the metal corrugated pipe may be deformed and expanded due to welding, making it difficult for the refrigerant pipe 11 to be clamped into the first fixation groove 41. In the embodiment of the present application, as shown in FIG. 4 to FIG. 6, the first fixation groove 41 is provided with a first opening side 43, the refrigerant pipe 11 is clamped into the first fixation groove 41 from the first opening side 43, and the width of the first fixation groove 41 increases along a direction adjacent to the first opening side 43. That is, the first opening side 43 of the first fixation groove 41 is configured as an open form, thereby providing a certain degree of freedom for the mounting of the refrigerant pipe 11 and reducing the possibility of difficult mounting due to deformation of the refrigerant pipe 11. At this time, to reduce the possibility of the refrigerant pipe 11 detaching, the first fixation groove 41 is provided at a side of the fixation block 4 facing the casing 2, and the first opening side 43 is provided facing the casing 2.

[0070] Since the drain pipe 12 is configured as a flexible hose, to reduce the possibility of the drain pipe 12 detaching from the second fixation groove 42, in the embodiment of the present application, the second fixation groove 42 is provided with a second opening side 44, the drain pipe 12 is clamped into the second fixation 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. In an embodiment, 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 block the detachment of the drain pipe 12. As can be seen from the attached drawings, the second opening side 44 is formed by providing a mounting notch on one side of the second fixation groove 42.

[0071] In an embodiment, as shown in FIG. 3, a buffer member 26 is provided at a side of the second fixing position 23 facing the fixation block 4. The buffer member 26 is abutted between the fixation block 4 and the casing 2, thereby providing a buffering function for the fixation block 4 and avoiding direct contact between the refrigerant pipe 11 and the casing 2. The buffer member 26 may be configured as a sponge sheet or a rubber sheet, etc., and the buffer member 26 is directly bonded to the outer side of the casing 2.

[0072] To facilitate the fixing of the fixation block 4, in the embodiment of the present application, a second pressing member 5 is further provided at the second fixing position 23, and the second pressing member 5 presses the fixation block 4 against the second fixing position 23 to fix the drain pipe 12 and the refrigerant pipe 11.

In an embodiment, a limit groove 45 is provided at a side of the fixation block 4 away from the casing 2, and the second pressing member 5 is clamped into the limit groove 45, thereby providing a barrier for the detachment of the fixation block 4 relative to the second pressing member 5 and reducing the possibility of failure of the fixing at the second fixing position 23 during use.

[0074] To facilitate the processing of the casing 2, the casing 2 comprises two main shell parts and a mounting shell part, the two main shell parts are spliced with the mounting shell part. The first fixing position 21 and the second fixing position 23 are provided at the mounting shell part, so that the main shell parts and the mounting shell part are processed separately and then spliced together, thereby facilitating the processing of the casing 2.

[0075] As shown in FIG. 1 to FIG. 5, in the embodiment of the present application, two first installation seats 24 spaced apart are provided at the first fixing position 21, the first pressing member 3 is configured as a first pressing hoop, and two ends of the first pressing hoop are respectively mounted at the two first installation seats 24; two second installation seats 25 spaced apart are provided at the second fixing position 23, the second pressing member 5 is configured as a second pressing hoop, and two ends of the second pressing hoop are respectively mounted at the two second installation seats 25.

[0076] In an embodiment, the first fixing position 21 has two first installation seats 24 spaced apart, the two first installation seats 24 spaced apart are respectively provided at opposite sides of the flexible connection assembly 1. One end of the first pressing member 3 is mounted at one of the two first installation seats 24, and another end of the first pressing member 3 bypasses the flexible connection assembly 1 and is mounted at another of the two first installation seat 24, thereby pressing the flexible connection assembly 1 against the first fixing position 21, avoiding direct mounting of the first pressing member 3 with the casing 2, and reducing the mounting difficulty of the first pressing member 3. The first installation seat 24 may be bonded, clamped, or fastened to the casing 2 through fasteners; or the first installation seat 24 is integrally formed with the casing 2.

[0077] The second fixing position 23 is provided with two second installation seats 25 spaced apart, the two second installation seats 25 spaced apart are respectively provided at opposite sides of the flexible connection assembly 1. One end of the second pressing member 5 is mounted at one of the two second installation seats 25, and another end of the second pressing member 5 bypasses the flexible connection assembly 1 and is mounted at another of the two second installation seat 25, thereby pressing the flexible connection assembly 1 against the second fixing position 23, avoiding direct mounting of the second pressing member 5 with the casing 2, and reducing the mounting difficulty of the second pressing member 5. The second installation seat 25 may be bonded, clamped, or fastened to the casing 2 through fasteners; or the second installation seat 25 is integrally formed with the casing 2.

[0078] To facilitate the mounting of the first pressing member 3, in the embodiment of the present application, a first pre-mounting structure is provided at the first installation seat 24, and the first pressing hoop and the first installation seat 24 are fixed by a first fastener. In an embodiment, the first pre-mounting structure can realize the preliminary fixing of the first pressing hoop and the first installation seat 24, so that when the operator fixes the first pressing hoop and the first installation seat 24 through the first fastener subsequently, there is no need to additionally fix the first pressing hoop, thereby facilitating the mounting of the first pressing hoop.

[0079] In an embodiment, the first mounting structure comprises two first clamp parts 241 respectively provided at upper and lower sides of the first installation seat 24, and the two first clamp parts 241 are respectively clamped at upper and lower sides of the first pressing hoop. In an embodiment, the two first clamp parts 241 are respectively provided at the upper and lower sides of the first pressing hoop, thereby ensuring the stability of the preliminary fixing of the first pressing hoop, and the first clamp parts 241 are directly clamped at the edge of the first pressing hoop, so that there is no need to correspondingly set clamp parts on the first pressing hoop, thereby facilitating the processing of the first pressing hoop.

[0080] The extending direction of the upper and lower sides of the first installation seat 24 is the axial direction of the flexible connection assembly 1. Since the first installation 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, the extending direction of the upper and lower sides of the first installation seat 24 is the vertical direction of the indoor unit 1000. In an embodiment, the first pressing hoop and the first installation seat 24 may be fixed only through the first fastener, or fixed only through clamping or bonding.

[0081] To facilitate the mounting of the first pressing member 3, in the embodiment of the present application, a second pre-mounting structure is provided at the second installation seat 25, and the second pressing hoop and the second installation seat 25 are fixed by a second fastener. In an embodiment, the second pre-mounting structure can realize the preliminary fixing of the second pressing hoop and the second installation seat 25, so that when the operator fixes the second pressing hoop and the second installation seat 25 through the second fastener subsequently, there is no need to additionally fix the second pressing hoop, thereby facilitating the mounting of the second pressing hoop.

[0082] In an embodiment, the second mounting structure comprises two second clamp parts 251 respectively provided at upper and lower sides of the second installation seat 25, and the two second clamp parts 251 are respectively clamped at upper and lower sides of the second pressing hoop. In an embodiment, the two second clamp parts 251 are respectively provided at the upper and lower sides of the second pressing hoop, thereby ensuring the stability of the preliminary fixing of the second pressing hoop, and the second clamp parts 251 are directly clamped at the edge of the second pressing hoop, so that there is no need to correspondingly set clamp parts on the second pressing hoop, thereby facilitating the mounting of the second pressing hoop.

[0083] The extending direction of the upper and lower sides of the second installation seat 25 is the axial direction of the flexible connection assembly 1. Since the first installation 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, the extending direction of the upper and lower sides of the second installation seat 25 is the vertical direction of the indoor unit 1000. In an embodiment, the second pressing hoop and the second installation seat 25 may be fixed only through the second fastener, or fixed only through clamping or bonding.

[0084] As shown in FIG. 1 to FIG. 5, in the embodiment of the present application, the flexible connection assembly 1 further comprises a power supply wire 15, the casing 2 is further provided with a second installation port 27, the second installation port 27 is located between the first fixing position 21 and the second fixing position 23, the power supply wire 15 passes through the second installation port 27 and is inserted into the sleeve 14, and the power supply wire 15, the refrigerant pipe 11, and the drain pipe 12 are jointly fixed at the first fixing position 21.

[0085] In an embodiment, the flexible connection assembly 1 further comprises a power supply wire 15. The refrigerant pipe 11, the drain pipe 12, and the power supply wire 15 are inserted into the sleeve 14, thereby facilitating the mounting of the indoor unit 1000 and the outdoor unit. However, only the first fixation groove 41 and the second fixation groove 42 are provided at the second fixing position 23, and the power supply wire 15 and the drain pipe 12 are jointly fixed in the second fixation groove 42. At this time, the power supply wire 15 may exert a squeezing effect on the drain pipe 12, affecting the flow rate of the drain pipe 12. Therefore, to reduce the possibility of the drain pipe 12 being squeezed, the casing 2 is further provided with a second installation port 27, the second installation port 27 is located between the first fixing position 21 and the second fixing position 23. The power supply wire passes through the second installation port 27 and then is inserted into the sleeve 14, thereby avoiding fixing the power supply wire 15 at the second fixing position 23, and the power supply wire 15 is fixed at the second fixing position 23 together with the refrigerant pipe 11, the drain pipe 12, and the sleeve 14, thereby improving the structural integrity of the flexible connection assembly 1.

[0086] To facilitate the power supply wire 15 passing through the second installation port 27, in the embodiment of the present application, the second installation port 27 is communicated with the first installation port 22, and a wire gathering part 271 protruding inward is provided at a side of the second installation port 27 facing the first installation port 22, and the wire gathering part 271 is configured to limit the power supply wire 15. In an embodiment, since the first installation port 22 is configured for the refrigerant pipe 11 and the drain pipe 12 to pass through, and the second installation port 27 is only configured for the power supply wire 15 to pass through, the area of the first installation port 22 is greater than that of the second installation port 27. The small area of the second installation port 27 results in great difficulty for the power supply wire 15 to pass through. Therefore, the second installation port 27 is communicated with the first installation port 22, so that the power supply wire 15 can first pass through the first installation port 22 and then be fixed to the second installation port 27, thereby facilitating the power supply wire 15 passing through the second installation port 27. To reduce the possibility of the power supply wire 15 detaching from the second installation port 27, a wire gathering part 271 protruding inward is provided at a side of the second installation port 27 facing the first installation port 22, thereby limiting the power supply wire 15. Moreover, the second installation port 27 is configured as a mounting notch provided in the first installation port 22 and extending toward the first fixing position 21, thereby facilitating the processing of the first installation port 22 and the second installation port 27.

[0087] In an embodiment of the present application, the air conditioner comprises an indoor unit, an outdoor unit, and a refrigerant pipe 11 respectively connected to the indoor unit and the outdoor unit. As shown in FIG. 7, the refrigerant pipe 11 is pre-positioned on a fixation panel 2000 through a fixation member 300 and fixed through a lock structure 400.

[0088] In an embodiment, the fixation panel 2000 is provided at the indoor unit, and may be used as an outer panel or an internal partition panel of the indoor unit; in an embodiment, the fixation panel 2000 is provided at the outdoor unit; in an embodiment, both the indoor unit and the outdoor unit may be provided with the fixation panel 2000.

[0089] In an embodiment, a first positioning part 210 and a second positioning part 220 are spaced apart on a panel surface 201 of the fixation panel 2000, and the refrigerant pipe 11 is provided between the first positioning part 210 and the second positioning part 220; the fixation member 300 is provided with a limit part 301 for limiting the refrigerant pipe, and a first fixation part 302 is in pre-positioning cooperation with the first positioning part 210, and a second fixation part 303 is in pre-positioning cooperation with the second positioning part 220; the fixation member 300 is fixedly connected to the fixation panel 2000 through the lock structure 400.

[0090] The refrigerant pipe 200 is a pipeline that plays a key role in the refrigeration system. The refrigerant pipe 200 is configured to connect the indoor unit and the outdoor unit of the air conditioner to transport and recover the refrigerant. The refrigerant pipe 200 is usually made of high-elasticity rubber or polyurethane, so that the hose has excellent compression resistance and corrosion resistance. The refrigerant pipe 200 is generally curved, so that it can flexibly adapt to various mounting environments and space constraints. The hose is usually connected using quick connectors. During the refrigeration process, the refrigerant pipe 200 is used to transport the refrigerant from the outdoor unit to the indoor unit to ensure the normal operation of the refrigeration system. When needed, the refrigerant pipe 200 can also be used to recover the refrigerant in the indoor unit to realize the recycling of the refrigerant. The volume of the refrigerant will change during heating and cooling processes. The application of hose can eliminate the stress of the pipeline to a certain extent and prevent the pipeline from loosening or breaking. The refrigerant pipe 200 can better adapt to various complex environments in industrial places such as buildings and equipment, such as restricted spaces, various angles and detailed components.

[0091] The technical solution of the present application realizes pre-positioning by using the fixation member 300 and the fixation panel 2000. When fixing the refrigerant pipe 11, the refrigerant pipe 11 can be first pre-positioned on the fixation panel 2000 through the first positioning part 210, the first fixation part 302, the second positioning part 220 and the second fixation part 303. The movement of the refrigerant pipe 11 is limited through the limit part 301, and there is no need to continuously press to fix the refrigerant pipe 11, thereby freeing the user's hands. Then the fixation member 300 is locked on the fixation panel 2000 through the lock structure 400 to fix the refrigerant pipe 11. In this way, the quick fixing and mounting of the hose are realized, which can be operated by a single person, with simple assembly, improving the production efficiency of the product and meeting the requirements of mass production.

[0092] To ensure that the refrigerant pipe 11 is safely and stably provided between the indoor unit and the outdoor unit of the air conditioner, and to prevent the refrigerant pipe 11 from being displaced or damaged due to vibration or other external forces during operation.

[0093] As shown in FIG. 8 to FIG. 10, the fixation member 300 comprises a main body section 310, and a first folded edge section 320 and a second folded edge section 330 provided at two sides of the main body section 310. As shown in FIG. 8, the limit part 301 is a clamp groove 311 formed by recessing the main body section 310 toward a side away from the refrigerant pipe 11, and an outer wall of at least a part of the refrigerant pipe 11 is clamped with the clamp groove 311; the first fixation part 302 is provided at the first folded edge section 320, and the second fixation part 303 is provided at the second folded edge section 330.

[0094] When in use, the fixation member 300 is clamped on the refrigerant pipe 11 through the clamp groove 311, and the fixation member 300 is moved to a suitable position, so that the first fixation part 302 and the first positioning part 210 of the first folded edge section 320, and the second fixation part 303 and the second positioning part 220 are aligned, so as to facilitate the assembly of the first fixation part 302 and the first positioning part 210, and the second fixation part 303 and the second positioning part 220, and pre-position the fixation member 300 on the fixation panel 2000, thereby limiting the movement of the refrigerant pipe 11, ensuring that the refrigerant pipe 11 is stably fixed on the fixation panel 2000, and will not be displaced due to vibration or other external forces, facilitating the subsequent locking operation of the fixation member 300. The fixation member 300 adopts a main body section 310 and two folded edge sections, featuring a simple structure, reduced material consumption, lower costs, optimized space utilization, and ease of mounting.

[0095] As shown in FIG. 9 and FIG. 10, in the embodiment, to simplify the mounting process, improve the stability and fixing effect of the fixation member 300, and facilitate maintenance and adaptation to different mounting environments, the first folded edge section 320 serves as the first fixation part 302, and the first fixation part 302 is in clamping cooperation with the first positioning part 210.

[0096] In an embodiment, the first positioning part 210 is configured as a positioning protrusion 211 protruding from the panel surface 201 of the fixation panel 2000, and a limit groove 212 is formed between the positioning protrusion 211 and the panel surface 201 of the fixation panel 2000; the first folded edge section 320 is clamped in the limit groove 212.

[0097] By using the first folded edge section 320 as the first fixation part 302, the structure of the fixation member 300 is simplified, the number of parts is reduced, and the production and manufacturing costs can be reduced. The clamping cooperation method usually does not require the use of additional tools. During mounting, the first folded edge section 320 only needs to be inserted into the limit groove 212 to complete the fixing, improving the mounting efficiency. The limit groove 212 formed between the positioning protrusion 211 and the fixation panel 2000 can limit the movement of the fixation member 300 on the panel, improve the stability of the fixation member 300, and prevent the fixation member 300 from being displaced due to vibration and other reasons. Moreover, this design enables the fixation member 300 to adapt to fixation panels 2000 of different thicknesses, and only the height of the positioning protrusion 211 or the depth of the limit groove 212 needs to be adjusted, thereby improving the flexibility of the design.

[0098] In an embodiment, the first fixation part 302 is provided as a protruding or projecting buckle structure located on the first folded edge section 320. The first positioning part 210 is provided as a corresponding groove or hole structure located on the fixation panel 2000 for receiving the buckle of the first fixation part 302. It can also be set oppositely.

[0099] As shown in FIG. 8, on this basis, the lock structure 400 comprises a first lock hole 410 provided at the first folded edge section 320 and a first installation hole 420 provided at the fixation panel 2000, and the first installation hole 420 corresponds to the first lock hole 410. The first folded edge section 320 is attached to the fixation panel 2000 under the action of a fastener 500. By screwing a screw into the first installation hole 420 and the first lock hole 410, the screw passes through the fixation panel 2000, thereby firmly fixing the fixation member 300 on the fixation panel 2000.

[0100] In the embodiment, to simplify the mounting process, improve the stability and fixing effect of the fixation member 300, and facilitate maintenance and adaptation to different mounting environments, the second folded edge section 330 serves as the second fixation part 303, and the second folded edge section 330 is in clamping cooperation with the second positioning part 220.

[0101] In an embodiment, the second positioning part 220 is configured as a positioning plate 2210 extending away from the panel surface 201 of the fixation panel 2000 and an elastic buckle 221 formed at the positioning plate 2210; and the second folded edge section 330 is in clamping cooperation with the elastic buckle 221.

[0102] As shown in FIG. 8 to FIG. 10, by using the second folded edge section 330 as the second fixation part 303, the structure of the fixation member 300 is simplified, the number of parts is reduced, and the production and manufacturing costs can be reduced. The clamping cooperation method usually does not require the use of additional tools. During mounting, the first folded edge section 320 is first inserted into the limit groove 212 to complete the pre-positioning on one side, and then the second folded edge section 330 is pressed to make the elastic buckle 221 limit the second folded edge section 330, thereby completing the pre-positioning process.

[0103] The design of the elastic buckle 221 usually simplifies and accelerates the mounting process without the need for tools. It only needs to insert the second folded edge section 330 into the elastic buckle 221 and fixation can be achieved by using the elasticity of the buckle. The elastic buckle 221 can provide a certain degree of elastic deformation, which enables the second folded edge section 330 to more easily adapt to the shape and size of the second positioning part 220 when clamping, and can maintain a good fit even if there are slight dimensional deviations or deformations.

[0104] As shown in FIG. 8, the elastic buckle 221 is formed by partially bending the positioning plate 2210, and a hollow groove 222 is formed on the positioning plate 2210. When the elastic buckle 221 is squeezed, the hollow groove 222 can also play a role of yielding to facilitate the resetting of the elastic buckle 221 for engagement with the second folded edge section 330.

[0105] In an embodiment, two positioning plates 2210 are provided at the upper and lower sides of the second folded edge section 330 respectively, and the elastic buckles 221 on the two positioning plates 2210 are clamped with the second folded edge section 330. In an embodiment, the positioning plate 2210 can be provided at the short side of the second folded edge section 330, and the extension range of the positioning plate 2210 is at least from the midpoint of the short side to both sides of the short side for more than half of the length of the short side.

[0106] In an embodiment, the second fixation part 303 is also provided as a protruding or projecting buckle structure located on the second folded edge section 330. The second positioning part 220 is provided as a corresponding groove or hole structure located on the fixation panel 2000 for receiving the buckle of the second fixation part 303.

[0107] On this basis, the lock structure 400 comprises a second lock hole 430 provided at the second folded edge section 330 and a second installation hole 440 provided at the fixation panel 2000, and the second installation hole 440 corresponds to the second lock hole 430. The second folded edge section 330 is attached to the fixation panel 2000 under the action of a fastener 500. By screwing a screw into the second installation hole 440 and the second lock hole 430, the screw passes through the fixation panel 2000, thereby firmly fixing the fixation member 300 on the fixation panel 2000.

[0108] Either one of the first lock hole 410 and the first installation hole 420 may be locked, or both of them may be locked, and either one of the second lock hole 430 and the second installation hole 440 may be locked, or both of them may be locked. It can be understood that through the pre-positioning function of the positioning parts of the fixation member 300 and the fixation panel 2000, the installer can operate with both hands to perform the fixing operation.

[0109] In addition, as shown in FIG. 9 and FIG. 10, in the embodiment, to avoid mounting errors and greatly improve assembly efficiency, the fixation member 300 and the refrigerant pipe 11 are designed with fool-proofing. The fixation member 300 and the refrigerant pipe 11 are provided symmetrically, so the installer does not need to judge the direction of the parts when fixing. In this way, effective fool-proofing is achieved, wrong mounting is avoided, and the mounting difficulty is reduced.

[0110] In an embodiment, the first folded edge section 320 and the second folded edge section 330 are symmetrical relative to the main body section 310. The first folded edge section 320 and the second folded edge section 330 have the same structure. During mounting, there is no need to distinguish them. The first folded edge section 320 can be inserted into the clamp groove 311, and the second folded edge section 330 can be clamped with the buckle; or the second folded edge section 330 can be inserted into the clamp groove 311, and the first folded edge section 320 can be clamped with the buckle.

[0111] As shown in FIG. 8 and FIG. 10, in an embodiment, the refrigerant pipe 11 has a first nozzle 101 and a second nozzle 102 on the cross-section perpendicular to the extension center line. The first nozzle 101 and the second nozzle 102 are important interfaces of the refrigerant pipe 11. The first nozzle 101 and the second nozzle 102 are used to connect different components in the air conditioning system to ensure the circulation of the refrigerant in the system, thereby realizing the refrigeration or heating function.

[0112] In the embodiment, the first nozzle 101 and the second nozzle 102 are symmetrical about the extension center line, and the cross-sections of the pipelines (not shown) inside the first nozzle 101 and the second nozzle 102 can be different to adapt to different flow requirements.

[0113] The cross-section of the refrigerant pipe is elliptical and symmetrical about the extension center line. In this way, when the fixation member 300 is clamped on the outer wall of the refrigerant pipe, that is, the outer wall of the refrigerant pipe 11 is adapted to the shape of the clamp groove 311 of the limit part 301, there is no need to distinguish between upper or lower, and front or back during clamping, which can reduce the mounting difficulty.

[0114] In an embodiment, a refrigerant medium is pre-charged in the refrigerant pipe 11. The air conditioner of the present application can be a split-type air conditioner that is convenient for users to install personally. The split-type air conditioner uses a flexible refrigerant pipe to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and the refrigerant is injected into the refrigerant circulation loop before the air conditioner leaves the factory. In this way, when the user installs the air conditioner by himself, he only needs to fix the indoor unit and the outdoor unit respectively. The fixation member 300 and the refrigerant pipe 11 are designed with fool-proofing, and the refrigerant pipe 11 is pre-charged with refrigerant. Even if the installer lacks relevant basic knowledge, it will not affect the installation. This design breaks the tradition that special technical personnel are required to install on-site and perform professional operations such as vacuuming, thereby reducing the installation difficulty and realizing personal installation by the user.

[0115] In an embodiment, the indoor unit and the outdoor unit can be integrated. At this time, the air conditioner is a mobile air conditioner, which does not need an external exhaust pipe or an outdoor unit, and all components are integrated into one unit. The indoor unit and the outdoor unit are connected through a flexible refrigerant pipe, and the compressor of the air conditioner can be provided in the indoor unit. However, the design is not limited to this. In an embodiment, the air conditioner of the present application can also be an ordinary split-type air conditioner.

[0116] In this way, the air conditioner is convenient for users to install personally. The air conditioner uses a flexible refrigerant pipe to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and the refrigerant is injected into the refrigerant circulation loop before the air conditioner leaves the factory. In this way, when the user installs the air conditioner by himself, he only needs to fix the indoor unit and the outdoor unit respectively, without assembling the refrigerant pipe and filling the refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user.

[0117] After providing the compressor in the indoor unit, the weight of the outdoor unit can be reduced, so that it is more convenient for the user to move the outdoor unit and find a suitable installation position, reducing the mounting difficulty and mounting labor costs, especially in areas where labor costs are high. To reduce noise, noise reduction treatment is performed on the compressor of the indoor unit, such as filling with noise reduction materials, and setting a buffer structure to reduce the transmission of compressor vibration.

[0118] In this way, the present application provides a more convenient, efficient and suitable air conditioner for user DIY installation. When fixing the refrigerant pipe, the fixation member is clamped on the outer wall of the refrigerant pipe, then one side of the fixation member is inserted into the clamp groove, and another side is clamped through the elastic buckle, which reduces the requirements on the operator's skills and improves the installation efficiency and safety. It greatly simplifies the installation process, enabling users to easily complete the fixing operation without relying on professional personnel.

[0119] In an embodiment of the present application, as shown in FIG. 11 to FIG. 19, the air conditioner 100 comprises an outdoor unit, a refrigerant pipe 200 and an indoor unit 3000. One end of the refrigerant pipe 200 is connected to the outdoor unit. The compressor provided in the indoor unit comprises an inner casing 3100 and an installation assembly 4000. An installation position 311 is provided at the outer surface of the inner casing 3100. A connection pipe 320 of the indoor unit 3000 extends to the installation position 311. Another end of the refrigerant pipe 200 is connected to the connection pipe 320. The installation assembly 4000 is fixed to the inner casing 3100 to fix the refrigerant pipe 200 and the connection pipe 320 to the inner casing 3100.

[0120] For reference, in the related art, the outdoor unit and the indoor unit 3000 are connected by special copper pipes. First, when the air conditioner is working, the compressor in the outdoor unit compresses the refrigerant, which changes from a gaseous refrigerant to a liquid state and releases heat. At the same time, the liquid refrigerant enters the condenser (radiator) of the outdoor unit, and the fan discharges the heat generated during compression to the outdoor space, so that the refrigerant becomes a liquid state with a lower temperature. Through the copper pipe (high-pressure pipe or liquid pipe), it enters the evaporator of the indoor unit 3000. Because the pressure of the refrigerant decreases after it enters the evaporator, the refrigerant vaporizes rapidly and absorbs a large amount of heat around the evaporator. The fan in the indoor unit 3000 can blow the "cold air" to the indoor space to achieve the cooling effect. Then the vaporized refrigerant comes out of the evaporator of the indoor unit 3000. The refrigerant passes through another relatively thick copper pipe (low-pressure pipe or gas pipe) connecting the indoor unit 3000 and the outdoor unit, and enters the compressor of the outdoor unit again. Here, the refrigerant pipe 200 is used to replace the copper pipe between the indoor unit 3000 and the outdoor unit in the related art. The refrigerant pipe 200 comprises an inner pipe assembly and a protective sleeve sleeved on the inner pipe assembly. The inner pipe assembly comprises the above-mentioned gas pipe and liquid pipe, that is, two refrigerant pipes. The inner pipe assembly can also comprise a water pipe, a fluid line, etc. The protective sleeve is sleeved on the inner pipe assembly to protect the inner pipe assembly and ensure the orderly arrangement of the inner pipe assembly.

[0121] The technical solution of the present application connects the indoor unit 3000 and the outdoor unit by using the refrigerant pipe 200, replacing the related art where the indoor unit 3000 and the outdoor unit are connected by special copper pipes. By virtue of the flexibility of the refrigerant pipe 200, the indoor unit 3000 and the outdoor unit can be prefilled with refrigerant before leaving the factory, thereby forming a refrigerant circulation loop between the indoor unit 3000 and the outdoor unit. In this way, the user can install the air conditioner by himself, thus making the installation of the air conditioner 100 more convenient. In addition, the refrigerant pipe 200 extends to the inner casing 3100 of the indoor unit 3000 and is connected to the interface of the evaporator of the indoor unit 3000. The refrigerant pipe 200 is fixed by the installation assembly 4000 to ensure the stability of the refrigerant pipe 200, prevent it from shaking, avoid loosening and other situations, and improve the quality of the product.

[0122] In an embodiment, the installation assembly 4000 can be a cable tie, a metal strap, etc.

[0123] As shown in FIG. 11, in the embodiment, for the convenience of fixing and ensuring a good fixing effect, a pre-positioning structure 5000 and a fixation structure 600 are provided between the installation assembly 4000 and the inner casing 3100.

[0125] In an embodiment, the installation assembly 4000 can be an integral member composed of the first installation member 4100 and the second installation member 4200.

[0126] The installation assembly 4000 is made of metal or hard plastic. By providing the pre-positioning structure 5000 on the installation assembly 4000, during the mounting of the outdoor unit of the air conditioner, the installation assembly 4000, such as the first installation member 4100 and the second installation member 4200, can be pre-fixed on the inner casing 3100 in advance. In this way, the subsequent screw locking process can be facilitated in a limited space. Compared with the related art, which requires applying external force to fix and align with the screw lock holes during mounting, the embodiment adopts the pre-fixation mode via the pre-positioning structure 5000, making the mounting process more convenient.

[0127] The first installation member 4100 and the second installation member 4200 are spaced apart along the connecting direction of the refrigerant pipe 200, which can achieve a good fixing effect with fewer parts. Compared with the integral way, the parts are smaller in volume, lower in mold opening and manufacturing costs, and more convenient in mounting.

[0128] In an embodiment, the refrigerant pipe 200 comprises an inner pipe assembly and a protective sleeve sleeved on the inner pipe assembly. A part of the inner pipe assembly is exposed outside the protective sleeve and connected to the pipeline of the indoor unit 3000.

The first installation member 4100 is fixed on the inlet copper pipe and outlet copper pipe (liquid pipe / gas pipe) of the indoor unit 3000 and adjacent to the connection of the refrigerant pipe 200, so as to ensure the stability of the copper pipe of the indoor unit 3000 and prevent it from shaking. The second installation member 4200 is fixed at the protective sleeve to ensure the stability of the refrigerant pipe 200 in the inner casing 3100. In this way, The refrigerant pipe 200, the inlet copper pipe and outlet copper pipe of the indoor unit 3000 are fixed at the inner casing 3100, and the connection part of the refrigerant pipe 200, the inlet copper pipe and outlet copper pipe is not easy to detach, ensuring stable connection. In this way, loosening is less likely to occur during the subsequent movement of the indoor unit 3000, which can ensure the product quality.

[0146] To ensure the strength of the protective shell 700, a reinforcement structure 730 is further provided in the protective shell 700. The reinforcement structure 730 is provided at the bottom of the protective shell 700.

[0147] In an embodiment, the reinforcement structure 730 is configured as a reinforcement rib 413.

[0148] In an embodiment, the reinforcement structure 730 can also be a connecting rod provided at the side wall of the protective shell 700.

[0149] As shown in FIG. 20, the connection between the refrigerant pipe 200 and the outdoor unit 800 is described as follows.

[0150] At present, in the air conditioner 100, the indoor unit 3000 and the outdoor unit 800 are assembled separately. During mounting, it is necessary to first assemble the indoor unit 3000 and the outdoor unit 800 respectively, then connect the pipelines between the indoor unit 3000 and the outdoor unit 800, and finally perform exhaust and refrigerant charging operations to ensure the normal operation of the air conditioner 100.

[0151] However, the connection of air conditioning pipelines and the charging of refrigerant are inconvenient for users to install, and professional personnel are required for operation, thus resulting in high labor costs. In the related art, the refrigerant circulation loop between the indoor unit 3000 and the outdoor unit 800 needs to be connected by special copper pipes. The copper pipes are hard pipes and are easy to break under force, the pre-connection between the indoor unit 3000 and the outdoor unit 800 cannot be completed before leaving the factory, users still need to connect the air conditioning pipelines and charge the refrigerant subsequently. The refrigerant pipe is used to replace the copper pipe in the related art. The flexibility of the refrigerant pipe enables the indoor unit and the outdoor unit to be connected together, so that the pipeline connection and refrigerant charging of the indoor unit and the outdoor unit can be completed in advance before leaving the factory. In this way, the user can use the air conditioner after the indoor unit 3000 and the outdoor unit 800 are mounted, which is convenient for the user to install by himself.

[0152] After pre-connecting the indoor unit 3000 and the outdoor unit 800 through the refrigerant pipe and pre-charging the refrigerant in the circulation loop of the refrigerant pipe, the indoor unit and the outdoor unit, it is necessary to ensure the stability of the connection between the refrigerant pipe and the indoor unit and avoid shaking. Because the partial pipelines of the compressor part of the outdoor unit 800 and the partial pipelines of the evaporator of the indoor unit 3000 are interfaces of copper pipes, it is necessary to ensure the stability of the connection between the refrigerant pipe, the indoor unit 3000 and the outdoor unit 800, and also to consider the convenience of mounting, to reduce the cost of part processing, and to reduce the assembly process.

[0153] In an embodiment, the outdoor unit 800 comprises an outer casing 810, a partition plate 820 and a fixation assembly 830. The partition plate 820 is provided in the outer casing 810. Another end of the refrigerant pipe 200 extends to the plate surface of the partition plate 820 and is connected to the pipeline of the outdoor unit 800. That is, another end of the refrigerant pipe 200 is connected to the connection pipe 320 marked in FIG. 20. The fixation assembly 830 is configured to fix another end of the refrigerant pipe 200 on the partition plate 820. The mounting structure and mounting form of the fixation assembly 830 can refer to the pre-positioning structure 5000 and the fixation structure 600 of the installation assembly 4000 in the indoor unit 3000, which will not be repeated here.

[0154] In summary, the air conditioner 100 of the present application can be a split-type air conditioner 100 that is convenient for users to install personally. A flexible refrigerant pipe is used to connect the indoor heat exchanger of the indoor unit 3000 of the air conditioner and the outdoor heat exchanger of the outdoor unit of the air conditioner, and the refrigerant is injected into the refrigerant circulation loop before the air conditioner leaves the factory. In this way, when the user installs the air conditioner by himself, he only needs to fix the indoor unit 3000 and the outdoor unit of the air conditioner respectively, without assembling the refrigerant pipe and filling the refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user. However, the design is not limited to this. In an embodiment, the air conditioner 100 of the present application can also be an ordinary split-type air conditioner 100.
