[0008] As a preferred technical solution of the above-mentioned air guide assembly provided by the present invention, there are multiple air guide plates, and multiple air ducts are respectively formed between the multiple air guide plates and the inner side walls opposite to the two enclosures.

[0009] As a preferred technical solution of the above-mentioned air guide assembly provided by the present invention, at least one of the two enclosures is provided with an annular slide rail coaxial with the fixed ring, and the enclosure provided with the annular slide rail is fixed relative to the fixed ring; the rotating ring is slidably connected to the annular slide rail.

[0010] As a preferred technical solution of the above-mentioned air guide assembly provided by the present invention, the enclosure provided with the annular slide rail among the two enclosures is fixedly connected to the fixed ring, and the other enclosure is fixedly connected to the fixed ring / the rotating ring.

[0011] As a preferred technical solution of the above-mentioned air guide assembly provided by the present invention, the air guide assembly also includes a motor and a main gear connected to the output shaft of the motor; the motor is fixed relative to the fixed ring, and the main gear is engaged with the rotating ring for transmission.

[0012] As a preferred technical solution of the above-mentioned air guide assembly provided by the present invention, the motor is located between the fixed ring and the rotating ring, and the inner periphery of the rotating ring is provided with transmission teeth meshing with the main gear; or, the motor is located outside the rotating ring, and the outer periphery of the rotating ring is provided with transmission teeth meshing with the main gear.

[0031] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] like Figure 1 and Figure 2 The indoor unit 01 of the cabinet air conditioner shown is provided with an exhaust outlet 011 on its front side, and the air outlet side of the fan is provided with an air outlet component A that can adjust the size of the air outlet, and the air outlet side of the air outlet component A is provided with an air guide component B that can change the direction of the air outlet.

[0033] It should be noted that although the present embodiment Figure 1 and attached Figure 2 While the air outlet assembly A and air guide assembly B are used in a cabinet-type air conditioner indoor unit, the type of air conditioner indoor unit is not fixed. Without departing from the principles of the present invention, those skilled in the art may adjust the air outlet assembly A and air guide assembly B as needed to suit specific applications. For example, the air guide assembly provided in this embodiment may also be used in a wall-mounted air conditioner indoor unit or a ceiling-mounted air conditioner indoor unit.

[0034] In order to solve the problem that the position of the air outlet on the existing air conditioner indoor unit cannot be adjusted during the cooling or heating process of the air conditioner indoor unit, resulting in a limited air outlet range of the air conditioner indoor unit and thus the cooling or heating effect of the air conditioner indoor unit cannot be fully exerted, the present embodiment provides an air guide assembly and an air conditioner indoor unit.

[0035] First, in an air guide assembly B provided in this embodiment, as Figure 1 、 Figure 2 and Figure 3 As shown, the wind guide assembly B includes a fixed ring 41, a rotating ring 42, a wind guide plate 43 and a surrounding plate (not shown in the figure, arranged in a direction parallel to the paper surface); the fixed ring 41 is coaxially arranged on the inner side of the rotating ring 42, and the rotating ring 42 is coaxially rotated relative to the fixed ring 41; one end of at least two wind guide plates 43 are respectively hinged to the fixed ring 41 at intervals, and the hinge axis of the wind guide plate 43 is parallel to the axis of the fixed ring 41, and the other end of the wind guide plate 43 is provided with a guide portion 431 and faces the rotating ring 42; the rotating ring 42 is provided with a plurality of guides facing the fixed ring 41. The guide rail 421 extends and is slidably connected to the guide portion 431, and the guide rail 421 is configured to drive the air guide plate 43 to rotate around its hinge axis (i.e., the hinge axis of the air guide plate 43 and the fixed ring 41) through the guide portion 431 when the rotating ring 42 rotates around the fixed ring 41; the two enclosures are perpendicular to the axis of the fixed ring 41 and are arranged at intervals on both sides of the fixed ring 41 and the rotating ring 42, and an air duct is formed between each adjacent air guide plate 43 and the inner side walls opposite to the two enclosures, and the air duct has an air inlet formed on the side of the fixed ring 41 and an air outlet formed on the side of the rotating ring 42.

[0036] For example, in order to achieve the sliding connection between the guide rail 421 of the rotating ring 42 and the guide portion 431 of the air guide plate 43, as shown in FIG. Figure 3 As shown, the guide portion 431 may be a guide post, and the guide rail 421 may have a strip-shaped guide groove or a strip-shaped guide hole slidably connected to the guide post.

[0037] Furthermore, to achieve a sliding connection between the guide rail 421 of the rotating ring 42 and the guide portion 431 of the air deflector 43, as another connection structure between the air deflector 43 and the rotating ring 41, a connecting rod can be hingedly connected to the guide portion 431 of the air deflector 43, and a slider hingedly connected to the other end of the connecting rod is slidably connected to the guide rail 421. In this manner, the rotation of the rotating ring 42 can also achieve the function of driving the air deflector 43 to rotate around the fixed ring 41, thereby changing the position of the air outlet of the air outlet assembly.

[0038] To enable the rotating ring 42 to rotate about the fixed ring 41, at least one of the two enclosures can be provided with an annular slide rail coaxial with the fixed ring 41. The enclosure with the annular slide rail is fixed relative to the fixed ring 41, and the rotating ring 42 is slidably connected to the annular slide rail. In this way, when the rotating ring 42 rotates on the annular slide rail, the guide portion 431 on the air deflector 43 slides on the guide rail 421 of the rotating ring 42, driving the air deflector 43 to rotate about its hinge axis, thereby adjusting the air outlet range of the air conditioner indoor unit 01.

[0039] At the same time, the panel with the annular slide rails can be fixedly connected to the fixed ring 41, and the other panel can be fixedly connected to the fixed ring 41 or the rotating ring 42. In addition, since the fixed ring 41 is fixedly connected to the frame of the air conditioner indoor unit 01, the panel with the annular slide rails can be fixedly connected to the frame of the air conditioner indoor unit 01, so that the rotating ring 42 and the fixed ring 41 can be rotated coaxially.

[0040] In an air guide assembly B provided in this embodiment, an air duct is formed between each adjacent air guide plate 43 and the inner sidewalls of the two opposing enclosures. The air duct has an air inlet formed on the side of the fixed ring 41 and an air outlet formed on the side of the rotating ring 42. One end of at least two air guide plates 43 is hinged to the fixed ring 41 at intervals. When the rotating ring 42 rotates around the fixed ring 41, the multiple guide rails 421 on the rotating ring 42 drive the air guide plates 43 to rotate around their hinge axes via the guide portions 431 slidably connected thereto. In this way, the position of the air outlet of the air conditioner indoor unit 01 can be adjusted by rotating the rotating ring 42 around the fixed ring 41, thereby adjusting the air outlet direction and range, thereby fully utilizing the cooling or heating effect of the air conditioner indoor unit 01.

[0041] As a preferred embodiment of the air guide assembly B provided in this embodiment, in order to improve the air guide range and air guide effect of the air guide assembly B of this embodiment, the air guide assembly B can have multiple air guide plates 43, and multiple air ducts are formed between the multiple air guide plates 43 and the inner side walls of the two enclosures. In this way, when the rotating ring 42 rotates, it simultaneously drives the multiple air guide plates 43 to rotate around the fixed ring 41, and simultaneously changes the air outlet direction of the air outlets of the multiple air ducts, which also increases the air outlet range of the air outlet assembly.

[0042] As a preferred embodiment of the air guide assembly B provided in this embodiment, to better control the air outlet range and direction of the air guide assembly B, the air guide assembly B also includes a motor (not shown) and a main gear 44 connected to the output shaft of the motor. The motor is fixed relative to the fixed ring 41, and the main gear 44 is meshed with the rotating ring 42. In this way, when the motor drives the main gear 44 to rotate, the main gear 44 also drives the rotating ring 42 to rotate, thereby achieving electrical control of the air outlet direction of the air guide assembly B.

[0043] One possible implementation is to locate the motor between the fixed ring 41 and the rotating ring 42, with the inner circumference of the rotating ring 42 provided with transmission teeth 422 that mesh with the main gear 44. Another possible implementation is to locate the motor outside the rotating ring 42, with the outer circumference of the rotating ring 42 provided with transmission teeth 422 that mesh with the main gear 44. It is understood that whether the motor is located inside or outside the rotating ring 42, the function of driving the rotating ring 42 to rotate around the fixed ring 41 can be achieved.

[0044] As a preferred embodiment of the air guide assembly B provided in this embodiment, to achieve relative rotation of the rotating ring 42 relative to the fixed ring 41, a rotating disk coaxial with the fixed ring 41 can be connected to one side of the rotating ring 42, and a motor can be connected to the main shaft of the rotating disk. In this way, when the motor drives the rotating disk to rotate, it can drive the rotating ring 42 to rotate around the fixed ring 41.

[0045] In another embodiment of the relative rotation arrangement of the rotating ring 42 relative to the fixed ring 41, the two enclosures can be fixed relative to the fixed ring 41, that is, when the rotating ring 42 rotates around the fixed ring 41, it also rotates relative to the two enclosures.

[0046] Then, in an air conditioner indoor unit 01 provided in this embodiment, the air conditioner indoor unit 01 includes an air guide assembly B as described in any of the aforementioned embodiments. In this way, by adjusting the position and air outlet range of the air guide assembly B, the air conditioner indoor unit 01 can fully exert the cooling or heating effect of the air conditioner indoor unit 01.

[0047] At the same time, the motor of the air guide component B of this embodiment can be communicated with the processor of the air conditioner indoor unit 01, and the processor automatically controls the air outlet direction of the air guide component B directly by receiving information such as indoor temperature and human position.

[0048] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-functional manner to combine new implementations to suit more specific application scenarios.

[0049] Furthermore, those skilled in the art will appreciate that although some embodiments described herein include certain features that are included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of the present invention and to form different embodiments. For example, in the claims of the present invention, any of the claimed embodiments may be used in any combination.

[0050] Thus far, the technical solutions of the present invention have 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 scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
