[0043] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0044] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0046] like Figures 1 to 3 As shown in the embodiment of this disclosure, the air guide structure 10 for an indoor unit includes: an air guide plate 100, a latch 200, and a rotating arm 300. A support arm 110 is provided on the air guide plate 100. The latch 200 is installed on the support arm 110, and the latch 200 and the support arm 110 cooperate to form a positioning hole. A first end of the rotating arm 300 is used to connect to the body of the indoor unit, and a second end is installed in the positioning hole. The latch 200 achieves detachable locking of the air guide plate 100 by rotating and changing the shape of the positioning hole.

[0047] Specifically, by mounting the latch 200 onto the support arm 110 provided on the air guide plate 100, and by engaging the latch 200 with the support arm 110, a positioning hole can be formed. The shape of the positioning hole can be changed by rotating the latch 200 to alter the relative position of the latch 200 and the support arm 110.

[0048] Specifically, the positioning hole has two forms: an installation form and a locking form. When the latch 200 is rotated to a first predetermined relative position with the support arm 110, the positioning hole is in the installation form. In this form, the positioning hole allows the second end of the rotating arm 300 to be freely inserted or removed, thus enabling the installation or removal of the rotating arm 300. When the latch 200 is rotated to a second predetermined relative position with the support arm 110, the positioning hole is in the locking form. In this form, the positioning hole does not allow the second end of the rotating arm 300 to be freely inserted or removed, thus achieving a lock between the rotating arm 300 and the support arm 110.

[0049] Specifically, after the second end of the rotating arm 300 is inserted into the positioning hole, the rotation of the latch 200 will apply an axial constraint to the rotating arm 300 or release the axial constraint by changing the shape of the positioning hole. Therefore, by rotating and changing the shape of the positioning hole, the latch 200 can achieve the detachable locking of the air guide plate 100.

[0050] The air guide structure 10 for an indoor unit provided in this embodiment includes an air guide plate 100, a latch 200, and a rotating arm 300. A support arm 110 is provided on the air guide plate 100, and the latch 200 is installed on the support arm 110. The latch 200 and the support arm 110 cooperate to form a positioning hole. The first end of the rotating arm 300 is used to connect to the body of the indoor unit, and the second end is installed in the positioning hole. The latch 200 can switch the shape of the positioning hole by rotation, thus achieving a detachable lock for the air guide plate 100. In this way, when disassembling the air guide plate 100, it is not necessary to use tools or forcefully pry the latch as in related technologies; simply rotating the latch 200 to switch the shape of the positioning hole is sufficient. This reduces the risk of the air guide plate 100 falling off during operation due to latch failure. Therefore, this embodiment improves the ease of disassembly between the air guide plate 100 and the rotating arm 300, and improves the reliability of the air guide plate 100 after disassembly and installation.

[0051] like Figures 4 to 6 As shown, in some embodiments, the second end of the rotating arm 300 is provided with a rotating shaft 310 and a locking boss 320; the support arm 110 is provided with a first locking through hole 1121 that cooperates with the locking boss 320, and the latch 200 is provided with a second locking through hole 210 that cooperates with the locking boss 320; wherein, the length of the rotating shaft 310 is greater than the thickness of the second locking through hole 210; after the second end of the rotating arm 300 is installed in the first locking through hole 1121 through the second locking through hole 210, the second locking through hole 210 is switched to a locking state by controlling the latch 200 to rotate relative to the rotating shaft 310, thereby locking the rotating arm 300 onto the support arm 110.

[0052] Specifically, the rotating shaft 310 is used to insert into the positioning hole formed by the cooperation of the support arm 110 and the latch 200, serving as the rotation reference for the lock hole.

[0053] Specifically, the locking boss 320 is located at the end of the rotating shaft 310 and has a shape that can achieve limiting (e.g., cross-shaped, square or other non-circular cross-section shape). The locking boss 320 is used to limit the degree of freedom of rotation of the rotating arm 300.

[0054] Specifically, the first locking through hole 1121 is located on the support arm 110, and the shape of the first locking through hole 1121 matches the shape of the locking boss 320 so that the first locking through hole 1121 has the freedom to restrict the radial rotation of the rotating arm 300.

[0055] For example, such as Figure 4 and Figure 5 As shown, when the locking boss 320 on the rotating arm 300 is a cross boss, the first locking through hole 1121 on the support arm 110 that cooperates with the locking boss 320 is a cross through hole, and the size of this cross through hole is slightly larger than the size of the cross boss.

[0056] Specifically, the second locking through hole 210 is located on the latch 200. The shape of the second locking through hole 210 matches the shape of the locking boss 320, or is the same as the shape and size of the first locking through hole 1121. After the latch 200 is installed on the support arm 110, the second locking through hole 210 can be aligned with the first locking through hole 1121 by rotating the latch 200, so that the positioning hole formed by the latch 200 and the support arm 110 is in the installation state. At this time, the second end of the rotating arm 300 can be installed in the first locking through hole 1121 through the second locking through hole 210. After installation, the second locking through hole 210 can be misaligned with the first locking through hole 1121 by rotating the latch 200, so that the positioning hole formed by the latch 200 and the support arm 110 is in the locking state, locking the rotating arm 300 on the support arm 110 and restricting the radial and axial degrees of freedom of the rotating arm 300 relative to the support arm 110.

[0057] Specifically, by setting the length of the rotating shaft 310 to be greater than the thickness of the second locking through hole 210, it can be ensured that the rotating shaft 310 always passes through the latch 200, thus avoiding the situation where the latch 200 cannot rotate.

[0058] In this embodiment, the structure of misaligned interference of the two through holes (first locking through hole 1121 and second locking through hole 210) allows the locking boss 320 on the support arm 110 to be constrained from multiple directions. This prevents the air guide plate 100 from loosening or making abnormal noises during operation, and enhances the vibration resistance of the air guide plate 100. In this embodiment, when disassembling the air guide plate 100, it is not necessary to use tools or force to pry the buckle as in related technologies. Simply rotate the buckle 200 to align the first locking through hole 1121 and the second locking through hole 210, and then remove the locking boss 320 from the positioning hole. This improves the convenience of disassembling the air guide plate 100 and the rotating arm 300.

[0059] For example, 4 to Figure 6As shown, in some embodiments, the support arm 110 includes an arm body 111 and a mounting portion 112 disposed on the arm body 111. A first locking through hole 1121 is formed in the mounting portion 112; the mounting portion 112 is also provided with a positioning slide groove 1122, a first locking slide groove 1123 and a second locking slide groove 1124. The latch 200 is provided with a positioning latch 220 and a locking latch 230. Specifically, when the latch 200 is installed on the support arm 110, the positioning latch 220 is installed in the positioning groove 1122; when the locking latch 230 is rotated into the first locking groove 1123, the positioning hole is in the installation state, and the second end of the rotating arm 300 can be installed in the first locking through hole 1121 through the second locking through hole 210, or the rotating arm 300 can be removed from the support arm 110 through the first locking through hole 1121 and the second locking through hole 210; when the locking opening is rotated into the second locking groove 1124, the positioning hole is in the locking state, and the rotating arm 300 can be locked on the support arm 110.

[0060] Specifically, the positioning groove 1122 is located at the mounting portion 112 of the support arm 110, and the positioning buckle 220 is located at the latch 200. The positioning buckle 220 is used to cooperate with the positioning groove 1122. When the latch 200 is initially installed on the support arm 110, the positioning groove 1122 is used to guide the installation of the positioning buckle 220, ensuring the alignment of the latch 200 with the support arm 110, and ensuring the stability when rotating the latch 200.

[0061] Specifically, the first locking groove 1123 and the second locking groove 1124 are both located in the mounting part 112, and the locking buckle 230 is located in the latch 200. The locking buckle 230 is used to cooperate with the first locking groove 1123 and the second locking groove 1124.

[0062] Specifically, the first locking groove 1123 corresponds to the mounting configuration of the positioning hole. When it is necessary to mount the second end of the rotating arm 300 onto the support arm 110, or when it is necessary to remove the rotating arm 300 from the support arm 110, the latch 200 can be rotated so that the locking latch 230 is located in the first locking groove 1123, and the first locking through hole 1121 is aligned with the second locking through hole 210, so as to allow the insertion or removal of the second end of the rotating arm 300.

[0063] For example, such as Figure 7 As shown, the locking buckle 230 is located in the first locking groove 1123.

[0064] Specifically, the first locking groove 1123 corresponds to the locking configuration of the positioning hole. When it is necessary to lock the second end of the rotating arm 300 onto the support arm 110, the latch 200 can be rotated so that the locking latch 230 is located in the second locking groove 1124, causing the first locking through hole 1121 and the second locking through hole 210 to be misaligned, thereby restricting the radial and axial degrees of freedom of the second end of the rotating arm 300 relative to the support arm 110.

[0065] For example, such as Figure 8 As shown, the locking buckle 230 is located in the second locking groove 1124.

[0066] In this embodiment, when the air guide plate 100 needs to be disassembled, unlike in related technologies, it is not necessary to use tools or force to pry open the latch. Simply rotate the latch 200 so that the locking latch 230 is positioned in the first locking groove 1123, aligning the first locking through hole 1121 and the second locking through hole 210. Then, the locking boss 320 can be removed from the positioning hole. When the air guide plate 100 needs to be installed, simply rotate the latch 200 so that the locking latch 230 is positioned in the first locking groove 1123, aligning the first locking through hole 1121 and the second locking through hole 210. Install the locking boss 320 on the support arm 110 into the positioning hole. Then, rotate the latch 200 so that the locking latch 230 is positioned in the second locking groove 1124, misaligning the first locking through hole 1121 and the second locking through hole 210. This improves the convenience of disassembling and installing the air guide plate 100 and the rotating arm 300.

[0067] like Figure 5 and Figure 6 As shown, in some embodiments, there are multiple positioning grooves 1122, and the positioning buckles 220 correspond one-to-one with the positioning grooves 1122.

[0068] Specifically, by providing multiple positioning grooves 1122 on the mounting part 112 and evenly distributing the multiple positioning grooves 1122 around the positioning hole, and correspondingly providing positioning buckles 220 and positioning grooves 1122, the precise alignment of the latch 200 during installation can be ensured, and the offset of the latch 200 during rotation can be prevented.

[0069] Optionally, the positioning groove 1122 is an arc-shaped guide groove.

[0070] Specifically, by setting the positioning groove 1122 as an arc-shaped guide groove, the guiding effect on the positioning buckle 220 can be enhanced.

[0071] like Figure 5 and Figure 6As shown, in some embodiments, the mounting portion 112 is provided with a locking protrusion 1125, and the latch 200 is provided with a locking groove 240 that cooperates with the locking protrusion 1125. The locking protrusion 1125 and the locking groove 240 cooperate to restrict the free rotation of the latch 200 relative to the support arm 110.

[0072] Specifically, the locking protrusion 1125 is located at the mounting portion 112 of the support arm 110, and the locking groove 240 is located at the latch 200. The locking groove 240 is used to cooperate with the locking protrusion 1125. The cooperation between the locking protrusion 1125 and the locking groove 240 can be used to limit the free rotation of the latch 200 relative to the support arm 110.

[0073] Optionally, the number of locking bumps 1125 can be one or two.

[0074] For example, when there is only one locking protrusion 1125, the locking protrusion 1125 is located on the same side of the second locking groove 1124. In this way, when the locking latch 230 is located in the second locking groove 1124, the free rotation of the latch 200 when no force is applied can be restricted.

[0075] For example, when there are two locking protrusions 1125, the locking protrusions 1125 are respectively disposed on the same side of the first locking slide groove 1123 and the second locking slide groove 1124. In this way, when the locking buckle 230 is located in the first locking slide groove 1123 or the second locking slide groove 1124, it can restrict the free rotation of the lock 200 when no force is applied.

[0076] In some embodiments, the first locking groove 1123, the second locking groove 1124, and the locking buckle 230 are all provided with anti-slip textures.

[0077] Specifically, by providing anti-slip textures in the first locking groove 1123 and the second locking groove 1124, as well as on the locking buckle 230, the risk of the locking buckle 230 rotating when it is not subjected to external force can be reduced when it is located in the first locking groove 1123 and the second locking groove 1124.

[0078] like Figure 1 As shown, there are at least two support arms 110, and at least two support arms 110 are symmetrically arranged at both ends of the air guide plate 100; wherein, the latch 200 and the rotating arm 300 correspond one-to-one with the support arm 110.

[0079] Specifically, by setting at least two support arms 110 and symmetrically arranging them at the left and right ends of the air guide plate 100, the secure connection between the air guide plate 100 and the indoor unit body via the rotating arm 300 can be ensured.

[0080] Understandably, each support arm 110 needs to be equipped with a latch 200 and a rotating arm 300 to form an independent locking unit.

[0081] In some embodiments, the support arm 110 is installed on the air guide plate 100 by snap-fit; or, the support arm 110 and the air guide plate 100 are integrally formed.

[0082] Specifically, the support arm 110 can be a separate part that is installed on the air guide plate 100 by snap-fit, or it can be a structure integrally formed with the air guide plate 100.

[0083] like Figure 9 As shown, the indoor unit 900 provided in this embodiment includes: a body 910 and an air guide structure 10 for the indoor unit as described above; the air guide structure 10 for the indoor unit is installed on the body 910.

[0084] like Figure 10 As shown, the air conditioner 1000 provided in this embodiment includes an outdoor unit 1010 and an indoor unit 900 as described above; the indoor unit 900 and the outdoor unit 1010 are connected.
