Description

Technical Field

[0001] This utility model relates to air conditioners, specifically providing an indoor unit and an air conditioner. Background Technology

[0002] In existing air conditioners, the air deflector is typically controlled by a drive assembly to rotate and adjust the airflow direction. This drive assembly is generally fixed to the side wall of the air conditioner housing and connected to the housing via multiple connectors. However, because end caps are usually installed on the exterior of the housing side wall, the installation space between the end cap and the housing is quite limited due to aesthetic design requirements. This makes the assembly and disassembly of the connectors extremely inconvenient, especially when repairing or replacing the drive assembly, as the end caps must be removed first, increasing maintenance costs and time. Furthermore, the confined space makes the connector connections prone to problems such as insecure installation or stripped threads due to limitations in tool operation, affecting the operational stability of the drive assembly.

[0003] Therefore, there is an urgent need in this field for an indoor air conditioning unit and an air conditioner to solve the above problems. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the installation structure of the air guide plate drive assembly to solve the problem of difficult assembly and maintenance in a narrow space.

[0005] In a first aspect, the present invention provides an indoor air conditioner unit, which includes a mechanism box and a cover. The mechanism box includes a first connecting portion, and the cover includes a second connecting portion. One of the first connecting portion and the second connecting portion is provided with a limiting hole, and the other is provided with a positioning post. The positioning post can pass through the limiting hole so that the mechanism box and the cover can be connected.

[0006] In the specific embodiment of the above-mentioned air conditioner indoor unit, one of the first connecting part and the second connecting part is provided with a first connecting hole, and the other is provided with a second connecting hole. The air conditioner indoor unit includes a connector that can pass through the first connecting hole and the second connecting hole to connect the mechanism box and the cover.

[0007] In the specific embodiment of the above-mentioned air conditioner indoor unit, the connector is a screw, the second connecting hole is a threaded hole, and the connector is screwed into the second connecting hole to connect the mechanism box and the cover.

[0008] In the specific embodiment of the above-mentioned air conditioner indoor unit, the mechanism box includes a plurality of first connecting parts, and the cover includes a plurality of second connecting parts, with the first connecting parts and the second connecting parts being arranged in a one-to-one correspondence.

[0009] In the specific embodiment of the above-mentioned air conditioner indoor unit, the housing includes three second connecting parts, which are disposed on the front inner wall, bottom inner wall and side inner wall of the housing.

[0010] In the specific embodiment of the above-mentioned air conditioner indoor unit, the air conditioner indoor unit includes an end cover, and the side outer wall of the cover is connected to the end cover.

[0011] In the specific embodiment of the above-mentioned air conditioner indoor unit, an opening is provided at the rear of the cover, and the limiting hole, the positioning post, the first connecting hole and the second connecting hole on the second connecting part are all arranged facing the opening.

[0012] In the specific embodiment of the above-mentioned air conditioner indoor unit, the mechanism box includes a first housing and a second housing connected to the first housing, and at least one of the first connecting parts is provided on both the first housing and the second housing.

[0013] In the specific embodiment of the above-mentioned air conditioner indoor unit, the air conditioner indoor unit further includes an air guide plate, and the mechanism box further includes a transmission component disposed in the mechanism box, the transmission component being connected to the air guide plate.

[0014] In a second aspect, the present invention provides an air conditioner, which includes the above-mentioned indoor unit.

[0015] With the above technical solution, this utility model achieves pre-positioning installation by inserting and matching the positioning post and the limiting hole, which can significantly reduce the alignment adjustment time when fastening the connecting parts, achieve precise guiding installation in the narrow space of the air conditioner, and provide a stable mechanical reference for subsequent connection of connecting parts, making the connection between the mechanism box and the cover more reliable and easier to assemble.

[0016] Furthermore, this utility model adds screw connection on the basis of positioning post limiting to form a dual fixing mechanism of "plug-in + thread". The matching design of the first connecting hole and the second connecting hole allows for a certain installation error, effectively avoiding component deformation caused by forced alignment. At the same time, compared with the pure connecting part connection method, it can reduce the fastening operation time and significantly improve assembly efficiency and connection reliability.

[0017] Furthermore, this utility model achieves multi-directional positioning connection between the mechanism box and the cover by setting multiple pairs of first connecting parts and second connecting parts. This not only enables rapid pre-positioning installation, but also forms a stable three-dimensional constraint relationship in a narrow space, allowing the assembly components to be reliably limited in multiple directions, effectively preventing displacement and loosening during operation, and significantly enhancing vibration resistance.

[0018] Furthermore, the outer side wall of the housing of this utility model is used to connect to the end cap, and the inner wall is provided with a second connecting part. The second connecting part is connected to the corresponding first connecting part through a positioning post and a limiting hole. This not only achieves a reliable connection between the mechanism box and the side of the housing, but also effectively overcomes the problem of inconvenient installation caused by the narrow side space in traditional structures. This simplified connection structure cleverly avoids interference with the installation space of the end cap, and while ensuring the connection strength, the overall assembly process can be completed without disassembling the end cap, significantly improving the convenience of maintenance.

[0019] Furthermore, the limiting hole, positioning post, first connecting hole, and second connecting hole on the second connecting part are all arranged facing the rear opening of the cover. This arrangement facilitates the installation of the mechanism box into the inside of the cover from the rear opening. Attached Figure Description

[0042] To address the difficulty of assembly and maintenance in confined spaces by improving the installation structure of the air guide plate drive assembly, this embodiment discloses an air conditioner, specifically a wall-mounted air conditioner.

[0043] Regarding the air conditioner, it should be noted that although the indoor unit in this embodiment is an air conditioner, and the air conditioner is a wall-mounted air conditioner, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art can use other arrangements in other embodiments. For example, the indoor unit can also be applied to a cabinet air conditioner, other types of air conditioners, or other devices requiring installation structures. These modifications do not depart from the basic principles of the present invention and therefore fall within the protection scope of the present invention.

[0044] Reference Figure 1 The air conditioner includes a mechanism box and a housing 2.

[0045] Reference Figure 2 The housing 2 specifically refers to the housing of the wall-mounted air conditioner indoor unit. The housing 2 is a shell structure comprising an integrally formed front portion 21, side portions 23, and bottom portion 22. The front portion 21 of the housing 2 is the part furthest from the wall when the wall-mounted air conditioner indoor unit is installed on the wall. The rear portion of the housing 2 is an opening for installing other components. The outer sidewalls of the housing 2 are used to connect the end cap 3, as detailed in [link to details]. Figure 3 .

[0046] Regarding the housing 2, it should be noted that although the housing 2 in this embodiment is a housing, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art can use other arrangements in other embodiments. For example, the housing 2 can also be configured as other structures on an air conditioner. These modifications do not depart from the basic principles of the present invention and therefore fall within the protection scope of the present invention.

[0047] The housing 2 includes a plurality of second connecting portions; in this embodiment, the number of second connecting portions is three. (Refer to...) Figure 4 A front second connecting portion 24 is provided on the inner wall of the front portion 21 of the casing 2. The front second connecting portion 24 includes a first positioning post 241 and a front second connecting hole 242, specifically a threaded hole.

Figure 5 A second bottom connecting portion 25 is provided on the inner wall of the bottom 22 of the cover 2. The specific shape of the second bottom connecting portion 25 is a lug facing the rear opening of the cover 2. The second bottom connecting portion 25 is provided with a second positioning post 251 and a second bottom connecting hole 252. The second bottom connecting hole 252 is specifically a threaded hole. The axial direction of the second positioning post 251 and the opening direction of the second bottom connecting hole 252 are both facing the rear opening of the cover 2. (Refer to...) Figure 6A second side connecting part 26 is provided on the inner wall of the side portion 23 of the cover 2. The specific shape of the second side connecting part 26 is a groove that faces the rear opening of the cover 2. A third positioning post 261 is provided on the second side connecting part 26, and the axial direction of the third positioning post 261 faces the rear opening of the cover 2.

[0048] Regarding the housing 2, it should be noted that although the housing 2 in this embodiment includes three second connecting parts, respectively disposed at the front 21, bottom 22, and side 23 of the housing 2, this arrangement is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art can employ other arrangements in other embodiments. For example, the second connecting parts can be disposed at the front 21, bottom 22, top, or edge of the housing 2, and the number of second connecting parts can be determined according to the shape and size of the mechanism box and the housing 2. These modifications do not depart from the basic principle of the present invention and therefore fall within the protection scope of the present invention.

[0049] Reference Figure 7 The mechanism box is the outer shell of the drive mechanism for the air guide plate. The mechanism box includes a first housing 14 and a second housing 15, which are detachably connected to form a complete housing structure. A transmission component is provided inside the mechanism box, which is connected to the air guide plate to control the movement of the air guide plate.

[0050] Regarding the mechanism box, it should be noted that although the mechanism box in this embodiment is a wind guide plate driving mechanism, and the mechanism box is specifically composed of a first housing 14 and a second housing 15, this arrangement is not a limitation of this utility model. Without departing from the principle of this utility model, those skilled in the art can also adopt other arrangements in other embodiments. For example, the mechanism box can also be set as other structures that need to be installed on the cover 2. These modifications do not depart from the basic principle of this utility model, and therefore will fall within the protection scope of this utility model.

[0051] In this embodiment, the first housing 14 includes two first connecting portions, hereinafter referred to as the front first connecting portion 11 and the bottom first connecting portion 12. The front first connecting portion 11 is correspondingly disposed to the front second connecting portion 24, and the front first connecting portion 11 is specifically shaped as a lug. The front first connecting portion 11 is provided with a first limiting hole 111 and a front first connecting hole 112. The bottom first connecting portion 12 is correspondingly disposed to the bottom second connecting portion 25, and the bottom first connecting portion 12 is specifically shaped as a lug. The bottom first connecting portion 12 is provided with a second limiting hole 121 and a bottom first connecting hole 122. The second housing 15 includes one first connecting portion, hereinafter referred to as the side first connecting portion 13, and the side first connecting portion 13 is correspondingly disposed to the side second connecting portion 26. The side first connecting portion 13 is specifically shaped as a lug, and the fifth connecting portion is provided with a third limiting hole 131.

[0052] Reference Figure 8 When connecting the mechanism box and the cover 2, the first positioning pin 241 is first inserted into the first limiting hole 111, the second positioning pin 251 is inserted into the second limiting hole 121, and the third positioning pin 261 is inserted into the third limiting hole 131. Simultaneously, the front first connecting hole 112 and the front second connecting hole 242 are aligned, and the bottom first connecting hole 122 and the bottom second connecting hole 252 are aligned. This embodiment also includes a first connector and a second connector, both of which are screws. The first connector passes through the front first connecting hole 112 and is screwed into the front second connecting hole 242; the second connector passes through the bottom first connecting hole 122 and is screwed into the bottom second connecting hole 252, so that the mechanism box is connected to the cover 2.

[0053] The first positioning post 241, the second positioning post 251, the third positioning post 261, the front second connecting hole 242, and the bottom second connecting hole 252 are all positioned facing the rear opening of the cover 2. This arrangement facilitates the connection between the mechanism box and the cover 2. The front second connecting hole 242 and the bottom second connecting hole 252 are both located away from the side 23 of the cover 2, and the second housing 15 and the side 23 of the cover 2 are connected only through the third positioning post 261 and the third limiting hole 131, without any connecting parts. This arrangement prevents the end cap 3 from affecting the connection between the cover 2 and the mechanism box.

[0054] Furthermore, the diameter of the third positioning post 261 is larger than the diameter of the first positioning post 241, and the diameter of the third positioning post 261 is larger than the diameter of the second positioning post 251. The third positioning post 261 is used to connect the second housing 15 of the mechanism box. The second housing 15 and the cover 2 are connected only through the third positioning post 261 and the third limiting hole 131. Using a large-diameter third positioning post 261 can improve the connection rigidity between the second housing 15 and the cover 2 and avoid misalignment deformation.

[0055] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
