Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an indoor unit. Background Art

[0002] The middle frame of the existing indoor unit is generally divided into an integral middle frame and a split middle frame. The integral middle frame installs the driving structure of the air guide door inside the middle frame. However, the integral middle frame limits the installation position of the driving structure of the air guide door and has poor installation stability.

[0003] The split middle frame includes a cover plate provided at a side end of the middle frame body. The cover plate is generally clipped to the side end of the middle frame body. However, the existing clipping method has problems such as difficulty in assembly and disassembly and poor assembly stability. Summary of the Invention

[0004] The problem solved by the present invention is that the existing cover plate and the middle frame body are difficult to disassemble and assemble, and the assembly stability is poor.

[0005] In order to solve the above problems, the present invention provides an indoor unit, which includes:

[0006] The middle frame body is provided with a hook and a plurality of hanging holes;

[0007] The end cover is connected to the side end of the middle frame body. A card block and multiple hooks are provided on the inner side of the end cover. The card block is engaged with the card hook, and the hook is used to hook into the hanging hole.

[0008] The indoor unit provided in this embodiment has at least the following beneficial effects:

[0009] The end caps and the middle frame body are connected by not only a clamping block and a hook to realize the middle frame body to limit the end caps upward, but also a hook is hooked into the hanging hole to realize the middle frame body to limit the end caps in five directions: left, right, front and back. This not only makes disassembly easy, but also improves the stability of the connection between the two.

[0010] In an optional embodiment, a mounting groove is opened at the side end of the middle frame body, the mounting groove is used to install a driving mechanism for driving the air guide door, and the end cover covers the mounting groove.

[0011] In this way, a mounting groove is opened at the end of the middle frame body, and the driving mechanism for driving the air guide door is installed in the mounting groove, and the mounting groove is covered with an end cover, thereby avoiding the driving mechanism from protruding relative to the end of the middle frame body, making the appearance of the indoor unit end flat and beautiful. Moreover, the mounting groove and the end cover can enhance the stability of the installation of the driving mechanism.

[0012] In an optional embodiment, the hook is arranged in the middle of the bottom wall of the installation groove, and the plurality of hanging holes are arranged around the hook.

[0013] In this way, the multiple hooks on the end cover are hooked into the hanging holes surrounding the hook, so that the force on the end cover can be evenly distributed and the entire end cover can be well fixed.

[0014] In an optional embodiment, the hanging hole is a special-shaped hole whose width gradually decreases from top to bottom.

[0015] In this way, the hook on the end cover is inserted into the upper part of the hanging hole and slides downward along the hanging hole to be snapped into the lower part of the hanging hole. Not only is the installation process simple, but also, under the action of the end cover's own gravity, the hook is not easy to fall off from the hanging hole. When the end cover needs to be removed from the middle frame body, it is only necessary to lift the end cover upward relative to the middle frame body to remove the end cover. The disassembly process is simple.

[0016] In an optional embodiment, the hanging hole includes an insertion section, a contraction section and a snap-on section that are sequentially connected from top to bottom. The insertion section is used for inserting the hook. The width of the insertion section is greater than the width of the snap-on section. The contraction section is used to guide the hook. The width of the contraction section gradually decreases from top to bottom. The snap-on section is used to snap on to the hook.

[0017] In this way, not only is the hanging hole simple in form and easy to manufacture, but the hook can also be easily inserted into the inserting section of the hanging hole and, under the guidance of the contracting section, directly enter the engaging section of the hanging hole, making the installation process simple and efficient.

[0018] In an optional embodiment, the hook includes a supporting portion, and the clamping block is clamped to the lower side of the supporting portion.

[0019] In this way, the support portion can limit the upward position of the block.

[0020] In an optional embodiment, the hook includes:

[0021] The two guide ribs are respectively arranged on opposite sides of the support portion, and the clamping block is passed through between the two guide ribs.

[0022] In this way, the two guide ribs can guide the block.

[0023] In an optional embodiment, the distance between the two guide ribs is greater than or equal to the width of the clamping block.

[0024] In this way, it is easy for the block to pass through the gap between the two guide ribs smoothly.

[0025] In an optional embodiment, a mounting through hole is provided on the middle frame body, and the hook further comprises:

[0026] The elastic part is installed in the installation through hole, one end of the elastic part is connected to the upper edge of the installation through hole, and the other end of the elastic part is connected to the support part and the two guide ribs.

[0027] In this way, under the action of the elastic part, the hook can withstand a certain deformation during the assembly process with the clamping block, so that the clamping block can pass over the supporting part and be clamped to the lower side of the supporting part.

[0028] In an optional embodiment, the hook includes:

[0029] A connecting seat connected to the inner wall of the end cover;

[0030] A horizontal connecting part, one end of which is connected to the connecting seat;

[0031] The vertical hook portion is connected to the other end of the horizontal connecting portion.

[0032] In this way, the hook has a simple structure, is easy to manufacture, and is easy to assemble into the hanging hole of the middle frame body.

[0033] In an optional embodiment, the card block includes:

[0034] a base connected to the inner wall of the end cover;

[0035] The clamping portion is connected to the base.

[0036] In this way, the card block has a simple structure, is easy to manufacture, and is easy to assemble into the card hook of the middle frame body.

[0037] In an optional embodiment, the end cap comprises:

[0038] A transverse plate, used for covering the top surface of the middle frame body;

[0039] The vertical plate is connected to the edge of the horizontal plate and is used to cover the side end surface of the middle frame body.

[0040] In this way, when the end cover slides downward along the middle frame body for assembly, the transverse plate can prevent the end cover from sliding downward excessively. After the transverse plate contacts the top surface of the middle frame body, the upward support strength of the middle frame body for the end cover can be further strengthened.

DETAILED DESCRIPTION

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] See also Figure 1 and Figure 2 This embodiment provides an indoor unit 1, which includes a middle frame body 2 and end covers 5. Mounting slots 21 are defined on both side ends of the middle frame body 2 for mounting a drive mechanism for driving an air guide door. Two end covers 5 are provided, connected to both side ends of the middle frame body 2 and covering the mounting slots 21. This prevents the drive mechanism from protruding from the end of the middle frame body 2, resulting in a smooth and aesthetically pleasing appearance at the end of the indoor unit 1. Furthermore, the mounting slots 21 and end covers 5 enhance the stability of the drive mechanism's installation and prevent dust and other impurities from entering the drive mechanism and affecting its transmission performance.

[0050] See also Figure 2 The bottom wall of the mounting slot 21 is provided with a hook 3 and multiple hanging holes 4. A block 7 and multiple hooks 6 are provided on the inner side of the end cap 5. The block 7 engages with the hook 3, and the hooks 6 are hooked into the hanging holes 4, thereby firmly connecting the end cap 5 to the middle frame body 2. In this way, the end cap 5 and the middle frame body 2 not only utilize the block 7 and hook 3 to engage with each other, thereby limiting the middle frame body 2's upward position on the end cap 5, but also utilize the hooks 6 to engage with the hanging holes 4, thereby limiting the middle frame body 2's downward position on the end cap 5 in five directions: left, right, front, and back. This not only facilitates disassembly but also provides a stable connection between the two. The term "front and back" here refers to the length of the middle frame body 2.

[0051] See also Figure 3The hook 3 is arranged in the middle of the bottom wall of the mounting groove 21, and a plurality of hanging holes 4 are arranged around the hook 3. In this embodiment, the number of hanging holes 4 is five, but in other embodiments, three or four hanging holes 4 may be provided. In this way, the multiple hooks 6 on the end cap 5 are hooked into the hanging holes 4 surrounding the hook 3, which can make the force on the end cap 5 uniform and the end cap 5 as a whole can be well fixed.

[0052] Preferably, the hanging hole 4 is a special-shaped hole whose width gradually decreases from top to bottom, such as an inverted trapezoid or a combination of a rectangle and a trapezoid. The term "from top to bottom" here refers to the direction from the top to the bottom of the space when the indoor unit 1 is actually installed. In this way, the hook 6 on the end cover 5 is inserted into the upper portion of the hanging hole 4 and slid downward along the hanging hole 4 to snap into the lower portion of the hanging hole 4. This not only simplifies the installation process, but also, due to the weight of the end cover 5 itself, the hook 6 is unlikely to fall off the hanging hole 4. When the end cover 5 needs to be removed from the middle frame body 2, it can be removed by simply lifting the end cover 5 upward relative to the middle frame body 2, making the removal process simple.

[0053] In this embodiment, the hanging hole 4 includes an insertion section 41, a contraction section 42, and a coupling section 43, which are sequentially connected from top to bottom. The insertion section 41 is used to insert the hook 6 and is wider than the coupling section 43. The contraction section 42 is used to guide the hook 6 and its width gradually decreases from top to bottom. The coupling section 43 is used to engage with the hook 6. This not only simplifies the shape of the hanging hole 4 and facilitates manufacturing, but also allows the hook 6 to be easily inserted into the insertion section 41 of the hanging hole 4 and, guided by the contraction section 42, directly into the coupling section 43 of the hanging hole 4, making the installation process simple and efficient.

[0054] See also Figure 4 The hook 3 includes a support portion 32, a guide rib 33, and an elastic portion 34. Correspondingly, a mounting hole 22 is provided on the bottom wall of the mounting groove 21. The elastic portion 34 is installed in the mounting hole 22. One end of the elastic portion 34 is connected to the upper edge of the mounting hole 22, and the other end of the elastic portion 34 is connected to the support portion 32 and the two guide ribs 33. The lower side of the support portion 32 is used to engage with the block 7. The two guide ribs 33 are respectively provided on opposite sides of the support portion 32, and the block 7 is located between the two guide ribs 33. In this way, the support portion 32 can limit the upward movement of the block 7, and the two guide ribs 33 can guide the downward movement of the block 7. Preferably, the spacing between the two guide ribs 33 is greater than or equal to the width of the block 7, so that the block 7 can smoothly pass through the gap between the two guide ribs 33. Under the action of the elastic portion 34 , the hook 3 can withstand a certain deformation during the assembly process with the clamping block 7 , so that the clamping block 7 can pass over the support portion 32 to engage the lower side of the support portion 32 and be inserted into the mounting through hole 22 .

[0055] See also Figure 2and Figure 5 The end cap 5 includes a transverse plate 51 and a vertical plate 52. The transverse plate 51 is used to cover the top surface of the middle frame body 2, and the vertical plate 52 is connected to the edge of the transverse plate 51. The vertical plate 52 is used to cover the side end surface of the middle frame body 2. In this way, when the end cap 5 slides downward along the middle frame body 2 for assembly, the transverse plate 51 can prevent the end cap 5 from sliding downward excessively. After the transverse plate 51 contacts the top surface of the middle frame body 2, it can further strengthen the upward support strength of the middle frame body 2 for the end cap 5.

[0056] Of course, the transverse plate 51 does not need to be a completely horizontal flat plate, but can be a roughly horizontal side plate, and the vertical plate 52 does not need to be a completely vertical flat plate, but can be a roughly vertical side wall.

[0057] See also Figure 6 The hook 6 includes a connecting base 61, a horizontal connecting portion 62, and a vertical hook portion 63. The connecting base 61 is connected to the inner wall of the end cover 5, the horizontal connecting portion 62 has one end connected to the connecting base 61, and the vertical hook portion 63 is connected to the other end of the horizontal connecting portion 62. In this way, the hook 6 has a simple structure, is easy to manufacture, and is easy to assemble into the hanging hole 4 of the middle frame body 2.

[0058] Moreover, the free end of the vertical hook portion 63 is further provided with a first inclined surface 64, which is used to guide the vertical hook portion 63 to slide into the hanging hole 4. When the vertical hook 6 moves vertically downward, the first inclined surface 64 first contacts the lower edge of the hanging hole 4. The first inclined surface 64 can guide the vertical hook portion 63 to slide into the hanging hole 4, thereby improving the efficiency of assembly.

[0059] The clamping block 7 includes a base 71 and a clamping portion 72, wherein the base 71 is connected to the inner wall of the end cover 5, and the clamping portion 72 is connected to the base 71. In this way, the clamping block 7 has a simple structure, is easy to manufacture, and is easy to assemble into the clamping hook 3 of the middle frame body 2.

[0060] Moreover, the free end of the clamping portion 72 is also provided with a second inclined surface 73, which is used to contact the bottom wall of the mounting groove 21 to prevent the free end of the clamping portion 72 from scratching the bottom wall of the mounting groove 21. In the process of the clamping portion 72 moving vertically downward, the second inclined surface 73 first contacts the bottom wall of the mounting groove 21. Compared with the sharp edge, it can prevent the free end of the clamping portion 72 from scratching the bottom wall of the mounting groove 21.

[0061] The assembly process of the indoor unit 1 provided in this embodiment is as follows:

[0062] First, align the hooks 6 on the end cover 5 with the insertion sections 41 of the hanging holes 4 on the middle frame body 2. Then, insert each hook 6 into the insertion section 41 of the corresponding hanging hole 4. Then, move the end cover 5 downward as a whole relative to the middle frame body 2. At the same time, the hooks 6 slide along the insertion section 41 and the contraction section 42 of the hanging hole 4 until the hooks 6 are engaged with the engaging section 43 of the hanging hole 4, and the engaging block 7 passes through the gap between the two guide ribs 33, is engaged with the lower side of the support portion 32, and is inserted into the mounting through hole 22.

[0063] The disassembly process of the indoor unit 1 provided in this embodiment is as follows:

[0064] First, the end cover 5 is moved upward as a whole relative to the middle frame body 2, so that the hook 6 is disengaged from the engaging section 43 of the hanging hole 4, the clamping block 7 is disengaged from the mounting through hole 22 of the clamping hook 3, and passes over the supporting portion 32. The end cover 5 is continuously controlled to move upward as a whole, so that the hook 6 slides along the contraction section 42 and the insertion section 41 of the hanging hole 4. Finally, the end cover 5 is moved horizontally away from the middle frame body 2, so that the hook 6 can be pulled out from the insertion section 41 of the hanging hole 4, and the end cover 5 can be removed from the middle frame body 2.

[0065] The indoor unit 1 provided in this embodiment has the following beneficial effects:

[0066] 1. The end cap 5 and the middle frame body 2 are not only connected by the clamping block 7 and the clamping hook 3 to realize the middle frame body 2 to limit the end cap 5 in the upward direction, but also use the hook 6 to hook into the hanging hole 4 to realize the middle frame body 2 to limit the end cap 5 in five directions: left, right, front and back. This not only facilitates disassembly, but also improves the stability of the connection between the two.

[0067] 2. A mounting groove 21 is formed at the end of the middle frame body 2. The drive mechanism for driving the air guide door is installed in the mounting groove 21 and covered with an end cover 5. This prevents the drive mechanism from protruding relative to the end of the middle frame body 2, making the end of the indoor unit 1 smooth and beautiful. Moreover, the mounting groove 21 and the end cover 5 can enhance the stability of the drive mechanism installation.

[0068] 3. The hanging hole 4 is a special-shaped hole with a width that gradually decreases from top to bottom. The hook 6 on the end cover 5 is inserted into the upper part of the hanging hole 4 and slides downward along the hanging hole 4 to snap the hook 6 into the lower part of the hanging hole 4. Not only is the installation process simple, but also, under the action of the end cover 5's own gravity, the hook 6 is not likely to fall off from the hanging hole 4. When the end cover 5 needs to be removed from the middle frame body 2, it only needs to be lifted upward relative to the middle frame body 2 to remove the end cover 5. The disassembly process is simple;

[0069] 4. Two guide ribs 33 are formed on the hook 3 to guide the clamping block 7. Moreover, the hook 3 has a simple structure and is easy to manufacture.

[0070] 5. The hook 3 includes an elastic portion 34. Under the action of the elastic portion 34, the hook 3 can withstand a certain deformation during the assembly process with the block 7, so that the block 7 can pass over the support portion 32 of the hook 3 and be connected to the lower side of the support portion 32 and inserted into the mounting through hole 22.

[0071] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
