Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to an air conditioner and its indoor unit. Background Technology

[0002] To improve assembly efficiency within the factory, the mounting solution for air conditioner indoor units typically employs a screwless design where the wall-mounted panel is clamped in place by clips on both the top and bottom sides. This structure prevents the wall-mounted panel from easily falling off during the factory production line, meeting the assembly efficiency requirements of large-scale production.

[0003] However, this mounting structure has significant drawbacks in the after-sales disassembly process. Once the wall-mounted panel is fixed to the wall and the air conditioner unit is installed on it, after-sales personnel can only disassemble the unit by forcibly pushing it upwards because it is installed flush against the wall. At this point, the lower clips on the unit remain firmly attached to the wall-mounted panel, and the upper clips can only be forcibly released from their deeply engaged position. This operation is extremely difficult, labor-intensive, and may damage the unit or the wall-mounted panel due to forced disassembly, severely impacting the convenience and efficiency of after-sales maintenance. Utility Model Content

[0004] One objective of this utility model is to overcome at least one technical defect in the prior art and provide an air conditioner and its indoor unit.

[0005] A further objective of this invention is to make the disassembly and removal of the air conditioner indoor unit from the wall-mounted panel convenient and labor-saving, and to prevent damage to components during the disassembly process.

[0006] Another further objective of this invention is to make the separation of the hook from the wall panel conform to the natural force application habits of the human hand, thereby reducing hand fatigue during operation.

[0007] Another further objective of this invention is to utilize the operating port to provide space for the disassembly tool to extend into, thereby reducing the difficulty of disassembly by using the tool to pry open the buckle.

[0008] Specifically, according to a first aspect of the present invention, the present invention provides an indoor air conditioning unit, including a housing and a frame disposed within the housing. The top of the back side of the frame is provided with at least one hanging groove, which is configured to hang from the top of the wall panel and onto the insert plate at the top of the wall panel to provide vertical support. The bottom back side of the frame is provided with at least one hook, which is configured to extend from the bottom of the wall panel into the insertion hole at the bottom of the wall panel to hook the wall panel. Furthermore, each hook has a corresponding buckle at its bottom, which is configured to move the hook downwards when subjected to a downward external force, thereby forcing the hook to separate from the wall panel.

[0009] Optionally, the hook includes a main body and a hook portion, the main body extending from front to back at the bottom of the frame, and the hook portion protruding upward from the main body and engaging with the front edge of the socket.

[0010] Optionally, the inverted buckle extends obliquely upward from front to back at the bottom of the main body.

[0011] Optionally, the bottom of the housing is provided with at least one operating port, which corresponds one-to-one with the buckle, for allowing a tool to approach the buckle and apply downward turning force to it.

[0012] Optionally, the operating port is arranged laterally offset from the corresponding inverted buckle.

[0013] Optionally, the lateral width of the operating port is 4mm to 8mm; and / or The lateral distance between the operating port and the inverted buckle is 1mm to 5mm.

[0014] Optionally, the frame has stress relief ports on both sides of the main body. The stress relief ports are configured to facilitate the buckle to move the hook downward when the buckle is subjected to a downward external force.

[0015] Optionally, the hook, the buckle, and the frame are integrally formed.

[0016] Optionally, the number of hanging slots is one, and it extends along the lateral direction of the frame; and / or The number of hooks is two, and they are spaced apart along the transverse direction of the skeleton.

[0017] According to a second aspect of the present invention, the present invention provides an air conditioner comprising the indoor unit of any one of the above-described embodiments.

[0018] This utility model's air conditioner indoor unit achieves a stable connection with the wall panel through a hanging groove and hooks, meeting the requirements of screwless assembly in the factory and preventing easy detachment during use. Simultaneously, the inverted design allows after-sales personnel to easily separate the hooks from the wall panel simply by applying downward force to the inverted clips, eliminating the need to forcibly push the machine upwards. This convenient and labor-saving operation effectively solves the problems of difficult disassembly and easily damaged components in existing air conditioner indoor units.

[0019] Furthermore, in this utility model of the air conditioner indoor unit, because the hook engages with the front edge of the socket, when after-sales personnel apply downward force to the hook, the hook will naturally disengage from the constraint of the front edge of the socket, thus separating the hook from the wall panel. This operation method conforms to the natural force application habits of the human hand, effectively reducing hand fatigue during operation and further improving the ease of disassembly.

[0020] Furthermore, the indoor unit of this utility model has an operating port at the bottom of its casing that corresponds to the inverted buckle. The operating port provides space for disassembly tools to be inserted. The tools can be directly inserted into the casing and positioned to the inverted buckle through the operating port, avoiding the problem of being able to see but not reach due to the casing blocking the view. This fundamentally solves the core obstacle to after-sales disassembly.

[0031] This embodiment provides an air conditioner indoor unit 10, the back of which is mounted on a wall panel 20, which is fixed to the wall.

[0032] like Figures 1 to 7As shown, the indoor unit 10 of the air conditioner generally includes a casing 110 and a frame 120, with the frame 120 disposed within the casing 110. At least one hanging groove 121 is provided on the top of the back side of the frame 120, configured to hook downwards onto the insert plate 211 at the top of the wall-mounted panel 20 for vertical support. At least one hook 122 is provided on the bottom of the back side of the frame 120, configured to extend upwards from the bottom of the wall-mounted panel 20 into the insert 221 at the bottom of the wall-mounted panel 20, thereby hooking the wall-mounted panel 20. Furthermore, each hook 122 has a corresponding buckle 123 at its bottom, configured to move the hook 122 downwards when subjected to a downward external force, forcing the hook 122 to separate from the wall-mounted panel 20.

[0033] It should be clarified that the improvement of this utility model only applies to the structure of the indoor unit 10 of the air conditioner, and does not make any changes to the structure of the wall mounting plate 20. For example... Figure 2 As shown, the wall panel 20 includes a first panel 210 and two second panels 220. The first panel 210 extends laterally, and the two second panels 220 extend vertically from both ends of the first panel 210, respectively, and are fixedly connected to the first panel 210 by rivets. Screw holes are provided on both the first panel 210 and the two second panels 220. During installation, the wall panel 20 is fixed to the wall using expansion screws passing through these screw holes.

[0034] The top of the first plate 210 has two insert plates 211. Each insert plate 211 is formed by extending forward from the main body 122a of the first plate 210 and then bending upward. This bending structure allows a gap to be left between the insert plate 211 and the wall so that the hanging slot 121 of the air conditioner indoor unit 10 can be hooked. The bottom of each second plate 220 is bent forward and the aforementioned insertion port 221 is provided at the bend to accommodate the insertion and engagement of the bottom hook 122 of the air conditioner indoor unit 10.

[0035] In this embodiment, the indoor unit 10 of the air conditioner is securely connected to the wall panel 20 via a mounting groove 121 and a hook 122, meeting the requirements of screwless assembly in the factory and preventing it from easily falling off during use. Simultaneously, the inverted clip 123 allows after-sales personnel to easily separate the hook 122 from the wall panel 20 by applying downward force to the clip 123, without having to forcibly push the machine upwards. This convenient and labor-saving operation effectively solves the problems of difficult disassembly and easily damaged components in the prior art for the indoor unit 10 of the air conditioner.

[0036] In some embodiments, the hook 122 includes a main body 122a and a hook 122b. The main body 122a extends from front to back at the bottom of the frame 120, and the hook 122b protrudes upward from the main body 122a and engages with the front edge of the socket 221.

[0037] Because the hook 122b engages with the front edge of the socket 221, when after-sales personnel apply downward force to the buckle 123, the hook 122b will naturally disengage from the constraint of the front edge of the socket 221, thus separating the hook 122 from the wall panel 20. This operation method conforms to the natural force application habits of the human hand, effectively reducing hand fatigue during operation and further improving the ease of disassembly.

[0038] In a specific example, the buckle 123 extends upward at the bottom of the main body 122a of the hook 122 in a direction from front to back. That is, the buckle 123 gradually lifts upward from the side away from the wall (front side) to the side closer to the wall (rear side), forming a structure with a sloping upper surface.

[0039] The inclined structure can be highly adapted to the force application requirements: during after-sales disassembly, it can directly adhere to the upper surface of the buckle 123 to apply downward pressure; due to the guiding effect of the inclined surface, this pressure can be efficiently converted into a force that drives the hook 122 to move downward as a whole, thereby enabling the hook part 122b of the hook 122 to quickly disengage from the constraint of the wall plate 20 insertion port 221, realizing the separation of the hook 122 from the wall plate 20.

[0040] After the hook 122 is separated from the wall mounting plate 20, the indoor unit 10 of the air conditioner only maintains contact with the plate 211 of the wall mounting plate 20 through the top mounting groove 121. At this time, there is no need to push the machine upward. Just apply a little force forward (away from the wall) to make the mounting groove 121 detach from the plate 211, and finally complete the complete disassembly of the indoor unit 10 of the air conditioner. The whole process is convenient and will not damage the parts.

[0041] In practical applications, the casing 110 of the indoor air conditioner unit 10 has good airtightness, and its bottom completely covers the internal frame 120, forming a closed space. Although this airtight structure can protect the internal components, it also brings practical difficulties to after-sales disassembly: even if after-sales personnel can see the inverted buckle 123 at the bottom of the frame 120 through the gaps in the casing 110, it is difficult for them to directly touch the inverted buckle 123 because their fingers cannot penetrate the casing 110 and the casing 110 blocks the operating space. Consequently, they cannot use external force to drive the hook 122 to separate from the wall panel 20, making the disassembly operation a dilemma of being able to see but not reach.

[0042] To address this issue, in some embodiments, the bottom of the housing 110 is provided with at least one operating port 111, which corresponds one-to-one with the buckle 123. The operating port 111 mainly provides space for disassembly tools to extend into.

[0043] Specifically, the tool can be smoothly inserted into the housing 110 through the operating port 111 and quickly positioned at the corresponding buckle 123. By applying downward force to the buckle 123 with the tool, the hook 122 can be moved, effectively avoiding the problem of the housing 110 obstructing the view and making it inaccessible. This fundamentally solves the core obstacle to after-sales disassembly and lays the foundation for efficient disassembly in the future.

[0044] In some embodiments, the operating port 111 and the corresponding inverted buckle 123 are arranged laterally (left-right). This design has dual technical value: On the one hand, the horizontally staggered spatial relationship provides the tool with an operational margin for oblique insertion. The tool does not need to be directly facing the inverted clip 123 to be inserted into the housing 110 at an angle and act precisely on the inverted clip 123, which is suitable for the conventional operating posture and tool usage habits of after-sales personnel.

[0045] On the other hand, the staggered arrangement can avoid the operation port 111 and the inverted buckle 123 forming a direct-view hole on the same vertical line. The structural shape of the bottom of the housing 110 can weaken the visual presence of the operation port 111. While meeting the functional requirements of tool insertion, it minimizes the impact of the opening of the housing 110 on the overall appearance of the air conditioner indoor unit 10, and achieves a balance between practicality and aesthetics.

[0046] The lateral width of the operating port 111 can be 4mm to 8mm. For example, 4mm, 5mm, 6mm, 7mm, 8mm, etc. This width range can fully accommodate the insertion needs of common after-sales disassembly tools (such as special pry tools with a thickness of 2mm to 5mm, narrow-head flathead screwdrivers, etc.), ensuring that the tools can smoothly pass through the operating port 111 to contact the snap 123, while also avoiding damage to the appearance integrity of the casing 110 due to an excessively wide opening.

[0047] The lateral distance between the operating port 111 and the inverted clip 123 can be 1mm to 5mm. For example, 1mm, 2mm, 3mm, 4mm, 5mm, etc. This distance provides sufficient oblique insertion allowance for the tool, allowing the tool to accurately act on the inverted clip 123 with a slight tilt, while also further weakening the visual presence of the operating port 111 through lateral misalignment, thus maximizing the balance between operational convenience and the aesthetic appearance of the casing 110.

[0048] In some embodiments, the operating port 111 can be opened in two ways: one is to extend forward from the rear edge of the bottom of the housing 110 to form a notch, and the other is to open directly upward from the bottom of the housing 110.

[0049] In some embodiments, the frame 120 has stress relief ports 124 formed on both sides of the main body 122a. The stress relief ports 124 are configured to facilitate the buckle 123 to drive the hook 122 to move downward when the buckle 123 is subjected to a downward external force.

[0050] The stress relief port 124 can be a notch structure opened on the frame 120. When the buckle 123 is subjected to a downward external force and causes the hook 122 to move downward, the stress relief port 124 provides a certain deformation space for the main body 122a of the hook 122, so as to avoid the main body 122a being difficult to deform due to excessive rigidity. This reduces the stress concentration at the connection between the hook 122 and the frame 120, so that the buckle 123 can smoothly drive the entire hook 122 to move downward, ensuring that the separation action of the hook 122 and the wall panel 20 is stable and reliable.

[0051] In some embodiments, the hook 122, the buckle 123, and the frame 120 are integrally formed. For example, the hook 122, the buckle 123, and the frame 120 are formed in one piece by injection molding or die casting. The three components do not require additional assembly methods such as splicing, welding, or screwing to form a seamless integral structure. This design not only simplifies the factory production process and eliminates component assembly steps to improve production efficiency, but also eliminates weak points in the connections between different components, significantly enhancing the connection strength between the hook 122 and the frame 120, and between the buckle 123 and the hook 122. This effectively avoids the risk of components loosening or falling off after long-term use or repeated disassembly, further ensuring the long-term reliability of the air conditioner indoor unit 10 mounting and disassembly structure.

[0052] For the mounting structure on the back side of the frame 120, a differentiated quantity configuration can be adopted to balance support stability and ease of operation. Specifically, the number of mounting slots 121 can be set to only one, and they are continuously arranged along the lateral direction (i.e., the left-right extension direction) of the frame 120. This design allows a single mounting slot 121 to form a large-area fit with multiple inserts 211 on the top of the wall panel 20, evenly bearing the weight of the indoor air conditioner 10 and avoiding tilting caused by uneven local force. The number of hooks 122 can be set to two, and they are distributed at intervals along the lateral direction of the frame 120, preferably symmetrically arranged on both sides of the bottom of the frame 120. The two hooks 122 can respectively cooperate with the two inserts 221 at the bottom of the wall panel 20, simultaneously restricting the movement of the indoor air conditioner 10 from both sides. This not only improves the mounting stability, but also ensures that the hooks 122 disengage synchronously during post-disassembly through symmetrical force application, avoiding jamming caused by force on one side.

[0053] This embodiment also provides an air conditioner, which includes an indoor unit 10 of any of the above embodiments. The indoor unit 10 is used with a common outdoor unit to achieve the normal cooling or heating function of the air conditioner.

[0054] Since the air conditioner has the indoor unit 10 of any of the above embodiments, the technical effects of the indoor unit 10 of any of the above embodiments will not be described in detail here.

[0055] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
