[0004] In the existing technology, an air conditioner includes an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are connected by connecting components such as refrigerant pipes. However, during the installation process, as the indoor unit or the outdoor unit moves, the connecting components are prone to swinging, which may cause the connecting components to detach from the internal components of the air conditioner they are connected to, or may cause them to be squeezed or collided with other components inside the air conditioner, affecting the stability of the connecting components and other components. Summary of the Invention

[0005] The main objective of this application is to propose a refrigerant pipe fixing structure and an air conditioner, which aims to reduce the possibility of the connecting components swinging inside the air conditioner.

[0012] In one embodiment, the pre-installation structure includes a limiting slit on one side of the refrigerant pipe along the axial direction and a snap-fit ​​groove on the other side of the refrigerant pipe along the axial direction. One of the two mounting parts passes through the limiting slit and abuts against the edge of the limiting slit away from the flexible connection assembly, while the other part is inserted into the snap-fit ​​groove along the axial direction of the flexible connection assembly.

[0013] In one embodiment, the pre-installation structure includes slots located on opposite sides of the refrigerant pipe along its axial direction, and the clamping member moves along the axial direction of the flexible connection assembly so that one of the mounting portions is correspondingly inserted into one of the slots.

[0014] In one embodiment, the groove has a slot for the mounting part to be inserted, and at least a portion of the slot is widened in a gradually increasing manner along the direction close to the refrigerant pipe.

[0015] In one embodiment, the partition includes a mounting body and a limiting stop that is bent and connected to the mounting body. The limiting stop and the mounting body are spaced apart to form the fastening groove. The groove is located at the edge of the limiting stop, and the edge of the limiting stop has a folded edge that bends away from the mounting body.

[0016] In one embodiment, the refrigerant pipe fixing structure includes a first mounting hole in the partition plate and a second mounting hole in the mounting portion, with fasteners passing through and securely connected to the first mounting hole and the second mounting hole.

[0017] In one embodiment, a portion of the partition plate is recessed relative to the fastener, the pre-installation structure is disposed in the recess, and the fastening structure is disposed between the recess and the mounting portion; and / or,

[0018] The fastener is provided with reinforcing ribs.

[0019] In one embodiment, the fixing block is further provided with a second slot for the connecting wires of the air conditioner to pass through.

[0020] This application also proposes an air conditioner, including an indoor unit, an outdoor unit, a refrigerant pipe connecting the indoor unit and the outdoor unit, and a refrigerant pipe fixing structure as described above.

[0021] In one embodiment, the refrigerant pipe fixing structure is disposed on the outdoor unit of the air conditioner and / or the indoor unit of the air conditioner; and / or,

[0022] The partition divides the interior space of the air conditioner into a first space and a second space. The first space is used for the installation of the heat exchanger of the air conditioner. The refrigerant pipe extends into the second space, and the fixing block and the fixing member are located on the side of the partition facing the second space.

[0044] This application proposes a refrigerant pipe fixing structure for an air conditioner, which includes an indoor unit and an outdoor unit. Refrigerant pipe 2 and other connecting components connect the indoor and outdoor units respectively. This air conditioner can be a split-type air conditioner that is easy for users to install themselves. In this case, refrigerant is injected into the refrigerant circuit of the refrigerant pipe 2 before the equipment leaves the factory. Thus, when users install the equipment themselves, they only need to fix the indoor and outdoor units separately, without needing to assemble the refrigerant pipe 2 or add refrigerant, thereby reducing installation difficulty and enabling individual installation. However, this design is not limited to this. In other embodiments, the air conditioner of this application can also be a common split-type air conditioner or an integrated air conditioner. The refrigerant pipe 2 is generally configured as a flexible refrigerant pipe 2.

[0045] Furthermore, this type of split-type air conditioner, which is convenient for individual installation, allows the compressor to be located inside the indoor unit, thus reducing the weight of the outdoor unit and facilitating its installation in outdoor spaces. Correspondingly, to reduce compressor noise, a noise reduction structure is required. This results in a relatively large overall weight for the indoor unit. To facilitate installation, the indoor unit can be a floor-standing unit, and it is equipped with casters at the bottom for easy installation and relocation.

[0046] The connecting assembly typically includes a drain pipe, connecting wires, and a sleeve. One end of the connecting wire and refrigerant pipe 2 connects to the internal components of the indoor unit of the air conditioner, while the other end passes through the sleeve and connects to the internal components of the outdoor unit. The drain pipe, along with the connecting wires and refrigerant pipe 2, passes through the sleeve, thereby draining the condensate produced by the indoor unit to the outdoor unit and then out of the air conditioner. This facilitates the drainage of condensate from the air conditioner to the outside, and also makes the connecting assembly a single unit connecting the indoor and outdoor units, thus facilitating the installation and transportation of the air conditioner. The connecting assembly is generally flexible for ease of installation. The sleeve can also be configured as a linear structure, wound around the outer circumference of the flexible refrigerant pipe 2 to form the sleeve. In other embodiments, only the refrigerant pipe 2 and the drain pipe may pass through the sleeve; or only the refrigerant pipe 2 and the connecting wire may pass through the sleeve; or only the refrigerant pipe 2 may pass through the sleeve; or only the drain pipe and the connecting wire may pass through the sleeve.

[0047] Please refer to Figures 1 to 8. In one embodiment of this application, the refrigerant pipe fixing structure includes:

[0048] Middle partition 11;

[0049] The fixing block 12 is provided with a first slot 121 through which the refrigerant pipe 2 of the air conditioner passes; and

[0050] The fastener 13 is installed on the partition 11 and the fixing block 12 is fixed on the partition 11 to fix the refrigerant pipe 2 to the partition 11.

[0051] Specifically, the fixing block 12 typically has two first slots 121, each corresponding to a refrigerant pipe 2, thereby reducing the possibility of deformation when the refrigerant pipe 2 is fixed to the partition 11 and improving the stability of the refrigerant pipe 2. The fixing member 13 can fix the fixing block 12 to the partition 11, thereby fixing the refrigerant pipe 2 to the partition 11, ensuring the refrigerant pipe 2 is fixed in the outdoor unit and / or indoor unit of the air conditioner, reducing the risk of the refrigerant pipe 2 becoming loose or collided with other components inside the air conditioner during transportation or installation, thus affecting the stability of the air conditioner.

[0052] This refrigerant pipe fixing structure can be installed on either the indoor or outdoor unit of the air conditioner. Regardless of its location, it is typically used to secure the portion of the refrigerant pipe 2 that protrudes from the sleeve, specifically near the end of the refrigerant pipe 2. This ensures a stable connection between the refrigerant pipe 2 and the corresponding components within the air conditioner. Therefore, this refrigerant pipe fixing structure is often located inside the indoor or outdoor unit of the air conditioner.

[0053] The partition 11 divides the internal space of the air conditioner into a first space and a second space. The first space is used for the installation of the air conditioner's heat exchanger, and the refrigerant pipe 2 extends into the second space. The fixing block 12 and the fixing component 13 are located on the side of the partition 11 facing the second space. Because this is a split-type air conditioner, refrigerant is injected into the refrigerant circuit before the equipment leaves the factory, eliminating the need for refrigerant pipe 2 assembly and refrigerant charging. However, to adapt to various installation environments, the length of the refrigerant pipe 2 and other connecting components needs to be set with sufficient margin. After installation, the excess length of the connecting components needs to be stored. To ensure aesthetics and reduce the impact of excessively long connecting components on the user's daily life, a partition 11 is provided. The partition 11 divides the internal space of the air conditioner into a first space and a second space, which are separated and not interconnected. The first space is used for the installation of the air conditioner's heat exchanger and fan assembly, serving as the main space of the air conditioner. The excess length of the connecting components is stored in the second space, thus facilitating the storage of the connecting components. Therefore, the connecting component is directly inserted into the second space through the housing, and the fixed bracket is located on the side of the partition plate 11 facing the second space, thereby fixing the section of the flexible connecting component inserted into the second space to the partition plate 11, thereby reducing the possibility of the flexible connecting component swinging in the second space.

[0054] When the partition 11 is installed on the outdoor unit of the air conditioner, it separates the outdoor heat exchanger and connecting components, and the electrical control box and other structures can also be located in the second space. When the partition 11 is installed on the indoor unit of the air conditioner, it separates the indoor heat exchanger and connecting components, and the compressor and other structures can be located in the second space. In other embodiments, the air conditioner can be an integrated air conditioner, in which case the partition 11 can be used to separate the indoor module and the outdoor module of the air conditioner. The first slot 121 is configured as a notch. When the fixing block 12 is attached to the partition 11 or the fixing member 13, the first slot 121 forms a complete locking hole, thereby facilitating the insertion of the refrigerant pipe 2.

[0055] Furthermore, the fixing block 12 is also provided with a second slot 122 for the connecting wire of the air conditioner to pass through. This second slot 122 is at least used for the connecting wire to be snapped through, thereby allowing the fixing block 12 to further secure the connecting wire, facilitating the overall fixation of the connecting assembly. In other embodiments, the second slot 122 can also be used to snap a drain pipe, with the connecting wire snapped into the gap between the drain pipe and the second slot 122. In other embodiments, the fixing block 12 is also provided with a third slot for the drain pipe of the air conditioner to pass through. The second slot 122 is configured as a notch, and when the fixing block 12 is attached to the partition plate 11 or the fixing member 13, the second slot 122 forms a complete snap hole, facilitating the insertion of the connecting wire.

[0056] In the embodiments of this application, the fastener 13 includes a pressing groove 131 and mounting portions 132 disposed on opposite sides of the pressing groove 131. The two mounting portions 132 are disposed on opposite sides of the refrigerant pipe 2 along the axial direction. The fixing block 12 is disposed in the pressing groove 131, and the mounting portions 132 are mounted on the partition plate 11 to press and fix the fixing block 12 to the partition plate 11. Specifically, the fastener 13 forms a clamping groove 131 to facilitate the fastener 13 engaging with the clamping groove 131, thus creating a semi-enclosing structure around the fastener 13. By fixing the clamping groove 131 to the axially opposite sides of the refrigerant pipe 2 on the partition plate 11, the refrigerant pipe 2 can be clamped and fixed to the partition plate 11, facilitating the fixation of the refrigerant pipe 2. The cross-sectional shape of the clamping groove 131 should match the cross-sectional shape of the fastener 13, and the opening of the clamping groove 131 towards the partition plate 11 can be flared, thus facilitating the fastener 13 engaging with the clamping groove 131 while ensuring stable engagement of the fastener 13. In other embodiments, the fastener 13 can also be configured as a cable tie, which, after securing the fastener block 12, is fixed to the partition plate 11.

[0057] Furthermore, the groove 1121 of the clamping groove 131 is bent and connected to a mounting part 132 on both sides of the fixing member 13. The mounting part 132 is installed on the middle partition 11, thereby pressing the fixing block 12 onto the middle partition 11, and also facilitating the installation between the clamping member and the middle partition 11.

[0058] The mounting part 132 is configured as flanges formed on both sides of the groove 1121 of the pressing groove 131, that is, the pressing groove 131 and the mounting part 132 are integrally stamped, which facilitates the assembly of the fastener 13 and ensures the structural strength of the fastener 13. Furthermore, the fastener 13 is provided with reinforcing ribs 134, thereby further improving the structural strength of the fastener 13. The reinforcing ribs 134 are partially stamped on the fixing bracket to facilitate the processing of the reinforcing ribs 134. To reduce structural redundancy, the width of the fastener 13 along the axial direction of the refrigerant pipe 2 can be less than or equal to the width of the fixing block 12 along the axial direction of the refrigerant pipe 2, as long as it can stably press and fix the fixing block 12 to the partition plate 11.

[0059] Referring again to Figures 1 to 8, in the embodiments of this application, the installation part 132 and the partition plate 11 are detachable for easy installation, thereby facilitating the assembly of the refrigerant pipe fixing structure.

[0060] Furthermore, the partition plate 11 is provided with a pre-installation structure 14, which pre-fixes the mounting part 132 to the partition plate 11, and a fixing structure 15 is provided between the mounting part 132 and the partition plate 11. Specifically, the pre-installation structure 14 is used for the initial installation positioning and pre-fixation of the fastener 13, thereby facilitating the positioning and installation of the fastener 13. The fixing structure 15 is used to further fix the fastener 13, thereby ensuring the installation stability of the fastener 13. This facilitates the installation of the fixing structure 15 without the need for manual labor or tools to position the fastener 13 during the fixing process of the fixing structure 15. In other embodiments, only the fixing structure 15 may be provided between the fixing bracket and the partition plate 11.

[0061] The pre-installation structure 14 is located on the partition plate 11, and the positioning and installation of the two are completed by the structure of the fastener 13 itself. Compared with the pre-installation structure 14 being located on the partition plate 11 and the mounting part 132 respectively, this solution helps to facilitate the processing and forming of the fastener 13.

[0062] In one embodiment, referring to Figures 1 to 4, the pre-installation structure 14 includes a limiting slit 111 on one side of the refrigerant pipe 2 along the axial direction and a retaining groove 112 on the other side of the refrigerant pipe 2 along the axial direction. One of the two mounting parts 132 passes through the limiting slit 111 and abuts against the edge of the limiting slit 111 on the side away from the flexible connection assembly, while the other is inserted into the retaining groove 112 along the axial direction of the flexible connection assembly.

[0063] Specifically, as shown in Figures 1 and 2, Figure 1 is a schematic diagram of the refrigerant pipe fixing structure when the fixing member 13 is not fully installed, and Figure 2 is a schematic diagram of the refrigerant pipe fixing structure when the fixing member 13 is fully installed. During installation, one of the two mounting parts 132 is first inserted into the limiting slit 111. Then, the fixing member 13 is deflected towards the middle partition 11, causing the fixing block 12 to engage in the pressing groove 131. Next, the fixing member 13 is slid along the axial direction of the refrigerant pipe 2, causing it to engage in the snap-fit ​​groove 112. One of the two mounting parts 132 passes through the limiting slit 111 and abuts against the edge of the limiting slit 111 on the side away from the flexible connection assembly, while the other is inserted into the snap-fit ​​groove 112. This completes the initial positioning and installation of the fixing member 13. This pre-installation structure 14 is inexpensive to install and has a simple structure.

[0064] The limiting orifice 111 is parallel to the axial direction of the refrigerant pipe 2 and has a certain margin for the mounting part 132 to slide inside it, thereby guiding the sliding of the fastener 13 to a certain extent. Because the limiting orifice 111 is stable, and in order to reduce the movement path of the fastener 13 during installation and facilitate the fastener 13 to be inserted into the retaining groove 112, the depth of the retaining groove 112 is generally less than 1 / 2 of the width of the mounting part 132.

[0065] In another embodiment, please refer to Figures 5 to 8. The pre-installation structure 14 includes slots 112 located on opposite sides of the refrigerant pipe 2 along the axial direction. The clamping member moves along the axial direction of the flexible connection assembly so that a mounting part 132 is correspondingly inserted into a slot 112.

[0066] Specifically, see Figures 5 and 6. Figure 5 shows a schematic diagram of the refrigerant pipe fixing structure when the fixing member 13 is not fully installed, and Figure 6 shows a schematic diagram of the refrigerant pipe fixing structure when the fixing member 13 is fully installed. During installation, the fixing member 13 is first moved towards the middle partition 11, causing the fixing block 12 to engage in the clamping groove 131. Then, the fixing member 13 slides along the axial direction of the refrigerant pipe 2, causing the two mounting parts 132 of the fixing member 13 to engage in the two retaining grooves 112 respectively (one mounting part 132 engages in one retaining groove 112), thus completing the initial positioning and installation of the fixing member 13. This pre-installation structure 14 is inexpensive to install and has a simple structure. The depth of the retaining groove 112 extends parallel to the axial direction of the refrigerant pipe 2, thus providing a certain degree of sliding guidance for the fixing member 13. To ensure stable positioning, the depth of the retaining groove 112 is generally greater than half the width of the mounting part 132.

[0067] Referring again to Figures 1 to 8, the retaining groove 112 further includes a slot 1121 for the mounting part 132 to be inserted into, and at least a portion of the slot 1121 is provided with a gradually widening width along the direction close to the refrigerant pipe 2. Specifically, the axial direction of the slot 1121 is approximately parallel to the axial direction of the refrigerant pipe 2, so that when the fastener 13 slides along the axial direction of the refrigerant pipe 2, it can be inserted into the retaining groove 112 through the slot 1121. Since the fastener 13 fixes the fixing block 12 to the partition plate 11 by pressing, a large pressing force is required to install the fastener 13 on the partition plate 11. Therefore, at least part of the slot 1121 is gradually widened in the direction close to the refrigerant pipe 2, that is, at least part of the slot 1121 is widened, so as to facilitate the installation part 132 to extend into the buckle slot 112. Then, the gradual widening of the slot 1121 further guides the sliding of the installation part 132, so as to facilitate the installation part 132 to be inserted into the buckle slot 112.

[0068] Understandably, the side of the buckle 112 facing the fixing block 12 also has an opening to ensure that the mounting part 132 can be inserted into the buckle 112 and slide within the buckle 112.

[0069] To facilitate the processing of the partition 11, in one embodiment, the partition 11 includes a supporting body 113 and a limiting edge 114 bent and connected to the supporting body 113. The limiting edge 114 and the supporting body 113 are spaced apart to form a snap-fit ​​groove 112. The groove 1121 is located at the edge of the limiting edge 114, and the edge of the limiting edge 114 is provided with a folded edge 115 bent away from the supporting body 113. Specifically, the supporting body 113 is the main body of the partition 11 and is used for the installation of the refrigerant pipe 2. The partition has a partial opening, and the edge of the opening is continuously bent and deformed to form a limiting edge 114. The limiting edge 114 and the supporting body 113 are spaced apart to form a snap-fit ​​groove 112. When the mounting part 132 is inserted into the snap-fit ​​groove 112, it often abuts against the limiting edge 114. The limiting edge 114 bends away from the mounting body 113 at the edge near the slot 1121, thus forming a bent flange and a gradually widening slot 1121. In summary, both the limiting edge 114 and the bent flange are integrally stamped from the partition plate 11, which facilitates the processing and forming of the pre-installation structure 14 and ensures the structural strength of the pre-installation structure 14. In other embodiments, the limiting edge 114 and the bent flange can also be integrally injection molded onto the partition plate 11.

[0070] The bending flange is usually located at the corner of the limiting stop 114 near the refrigerant pipe 2. This is the junction of the groove 1121 and the side opening of the buckle 112, which facilitates bending and forming, and further facilitates the processing of the partition plate 11.

[0071] Furthermore, the partition plate 11 is partially recessed 117 relative to the fixing member 13, the pre-installation structure 14 is located in the recess 117, and the fixing structure 15 is located between the recess 117 and the mounting part 132. Specifically, on the one hand, since the fixing member 13 fixes the fixing block 12 to the partition plate 11 by pressing, a large pressing force is required for the fixing member 13 to be inserted into the buckle groove 112. Therefore, the partial recess 117 of the partition plate 11 relative to the fixing member 13 helps to increase the opening width of the buckle groove 112, thereby facilitating the insertion of the mounting part 132 into the buckle groove 112 and providing a certain margin for the installation of the fixing block 12. On the other hand, the partial recess 117 of the partition plate 11 relative to the fixing member 13 helps to form an uneven structure on the partition plate 11, thereby increasing the strength of the partition plate 11, reducing the thickness of the partition plate 11, and contributing to the weight reduction of the product. The recess 117 is integrally stamped into the partition plate 11, and the shape of the recess 117 can be a regular shape such as a rectangle or a square, or it can be an irregular shape.

[0072] Referring again to Figures 1 to 8, to ensure the stable fixation of the fastener 13, in one embodiment, the fixing structure 15 includes a first mounting hole 116 provided in the partition plate 11 and a second mounting hole 133 provided in the mounting portion 132. A fastener 151 passes through and is securely connected to the first mounting hole 116 and the second mounting hole 133. Specifically, the fastener 13 is fixed to the partition plate 11 via the fastener 151, thereby facilitating the installation of the fastener 13 while ensuring its stability.

[0073] The fastener 151 can be configured as a fastening screw. When the pre-installation structure 14 has a mounting hole and a slot 112, the depth of the slot 112 is generally less than half the width of the mounting part 132. Therefore, the first mounting hole 116 is opened in the mounting body 113 and only needs to be opened on the side where the slot 112 is located. That is, this solution only requires one fastening screw to ensure the overall installation stability, thus facilitating the processing of the first mounting hole 116 and ensuring the overall installation stability. When the pre-installation structure 14 has two slots 112, the depth of the slot 112 is generally greater than half the width of the mounting part 132. Therefore, the first mounting hole 116 is opened in the limiting stop 114, and at least one of the two limiting stops 114 is provided with the first mounting hole 116.

[0074] In summary, this solution achieves initial positioning and installation by cooperating with the mounting slot 112 and the mounting part 132, or by cooperating with the mounting part 132 and the mounting slot 112. Then, fasteners 151 are used to further ensure the stability of the fastener 13. In other embodiments, the pre-installation structure 14 is another snap-fit ​​structure. The refrigerant pipe fixing structure includes a first mounting hole 116 in the fastener 13 and a second mounting hole 133 in the partition plate 11. Fasteners 151 pass through the first mounting hole 116 and connect to the second mounting hole 133. Alternatively, the pre-installation structure 14 can be configured as an adhesive such as tape. The fastener 13 is initially positioned and installed on the partition plate 11 using the adhesive, and then fixed in place by fasteners 151. After the fasteners 151 are fixed in place, the tape is removed.

[0075] This application also proposes an air conditioner, which includes an indoor unit, an outdoor unit, a refrigerant pipe 2 connecting the indoor and outdoor units, and a refrigerant pipe fixing structure. The specific structure of the refrigerant pipe fixing structure is as described in the above embodiments.
