Fig. 7 is a schematic block diagram of the guide plate 20 and the bushing 30 and the housing 10 of the air conditioner indoor unit 100 shown in fig. 1, fig. 8 is a schematic perspective view of the bushing 30 of the air conditioner indoor unit 100 shown in fig. 1, and fig. 9 is a schematic side view of the bushing 30 of the air conditioner indoor unit 100 shown in fig. 1. As shown in fig. 7, 8 and 9, in this embodiment, the indoor unit 100 of the air conditioner further includes a bushing 30 installed in the first installation hole 11, and an outer circumferential dimension of the fitting portion 221 is smaller than or equal to an inner diameter of the bushing 30. As shown in fig. 7, the bushing 30 is mounted and connected to the position-limiting portion 222, and the notch 224 and the hook 223 are located on the outer side of the bushing 30. In this embodiment, the liner 30 is made of plastic.

In this embodiment, as can be seen from fig. 8 and 9, the bushing 30 is provided with two oppositely arranged grooves, and by designing the grooves, the bushing 30 can be more easily installed in the first installation hole 11, because the material of the bushing 30 is a plastic part, and has a certain elastic deformation, when the bushing 30 is installed, two sides of the grooves can be pressed, so that the peripheral dimension of the bushing 30 becomes slightly smaller, and then the bushing 30 is installed in the first installation hole 11, at this time, two sides of the grooves can recover to the original shape, and can be clamped with the inner wall of the first installation hole 11, so that the bushing 30 is installed more stably.

In this embodiment, a straight distance a between the bottom of the notch 224 and the edge of the hook 223 is smaller than an inner diameter b of the bushing 30, so that the coupling shaft 22 can be easily inserted through the first mounting hole 11.

Fig. 10 is a schematic enlarged view of a portion C of the indoor unit 100 of the air conditioner shown in fig. 1. As shown in fig. 10 and referring to fig. 2, in this embodiment, the casing 10 is provided at the air blowing port 13 with at least one mounting bracket 14 having a second mounting hole, and the plate body 21 is provided with at least one connecting bracket 212 having a shaft body to pass through the second mounting hole through which the shaft body passes to connect the plate body 21 with the casing 10. This embodiment can prevent the guide plate 20 from being excessively moved by providing the shaft body and the second mounting hole. The at least one mounting bracket 14 is arranged in a one-to-one correspondence with the at least one connecting bracket 212.

In this embodiment, the number of the mounting brackets 14 and the number of the connecting brackets 212 are both two, and the two mounting brackets 14 and the two connecting brackets 212 are disposed at positions near the center of the guide plate 20. Specifically, the two mounting brackets 14 and the two connecting brackets 212 are respectively disposed at two sides of the middle position of the plate body 21, and are spaced from the connecting shaft 22 by a predetermined distance, which is equivalent to that the connecting points of the two connecting brackets 212 and the two ends of the guide plate 20 are uniformly arranged. In other embodiments, the number of the mounting brackets 14 and the connecting brackets 212 may be specifically set according to the length of the plate body 21. Here, the two mounting brackets 14 are integrally formed with the housing 10, and the two connecting brackets 212 are integrally formed with the guide plate 20. The preset distance may be specifically set according to the extension length of the plate body 21. For example, the longer the extending length of the plate body 21 is, the larger the preset distance may be set as appropriate. The shorter the extension length of the plate body 21 is, the smaller the predetermined distance can be set as appropriate. The design of the mounting bracket 14 and the connecting bracket 212 does not affect the rotation of the guide plate 20, and it is necessary to ensure that the guide plate 20 can rotate within the designed rotation angle.

In this embodiment, the guide plate 20 may be rotated 360 if the mounting bracket 14 and the attachment bracket 212 are not provided. If the mounting bracket 14 and the connecting bracket 212 are provided, the guide plate 20 can only rotate within a predetermined range of rotation, for example, 120 ° or 180 °, etc. The specific design may be set according to specific design requirements.

As can be seen in fig. 1 and 10, the mounting bracket 14 is located above the fence 10. In other embodiments, the mounting bracket 14 may also be disposed below the fence 10.

This embodiment can facilitate the end of the guide plate 20 to smoothly pass through the first mounting hole 11 for mounting, and prevent the guide plate 20 from falling off from the housing 10 by designing the notch 224 and the raised hook 223 on the connecting shaft 22 of the guide plate 20.

In other embodiments, an elastic buckle may be designed at the end of the guide plate 10, the elastic buckle passes through the first mounting hole 11 through elastic deformation of the buckle when passing through the first mounting hole 11, after the elastic buckle passes through the first mounting hole 11, the original shape is restored, the peripheral size of the buckle which restores the original shape at this time may be greater than the diameter of the first mounting hole 11, therefore, when the guide plate 10 receives the gravitational force of the guide plate itself and moves along the transverse direction, the buckle may be clamped with the outer side of the fixing plate 12, and cannot penetrate out of the first mounting hole 11, so that the guide plate 10 is limited, and the guide plate 10 is prevented from falling off from the first mounting hole 11.

In other embodiments, the fitting portion 221 of the guide plate 20 may be designed to be detachably coupled to the position-limiting portion 222, an end portion of the position-limiting portion 222 may be designed to have a threaded hole, and an outer circumference of one end of the fitting portion 221 may be designed to have a thread. When the guide plate 20 needs to be installed on the housing of the indoor unit of the air conditioner, the engaging portion 221 is not installed, that is, the engaging portion 221 is separated from the guide plate 20, and the limiting portion 222 passes through the first installation hole 11 and is engaged with the first installation hole 11. Then, one end of the fitting portion 221 having a thread on the outer circumference is screwed into the threaded hole of the stopper portion 222, thereby mounting the fitting portion 221 on the guide plate 20. Since the fitting portion 221 does not need to pass through the first mounting hole 11, at least one hook 223 only needs to be disposed at an end of the fitting portion 221 away from the screw thread, and the notch 224 does not need to be designed. When the guide plate 20 moves laterally under its own weight, the hook 223 may abut against the side wall of the fixing plate to limit the guide plate 20 from moving further. Here, it should be noted that the fitting portion 221 may be shaped as a shaft body, and a hook 223 is protruded on an outer circumference of the shaft body. Since the outer periphery of the matching portion 221 needs to be designed with threads to be inserted into the threaded hole of the limiting portion 222, generally, the outer periphery of the shaft body of the matching portion 221 is smaller than the limiting portion 222, which can be understood as being smaller than the diameter of the first mounting hole 11, so that when the protruding dimension of the hook 223 is designed, it is required to ensure that the overall outer periphery of the hook 223 and the shaft body is smaller than the diameter of the first mounting hole 11, and it can be ensured that the hook 223 cannot be disengaged from the first mounting hole 11. The straight distance between one side of the hook 223 close to the position-limiting portion 222 and the position-limiting portion 222 needs to be smaller than the diameter of the first mounting hole 11.

In another embodiment, the shape of the matching portion 221 may be designed as a stepped shaft body, which may be understood as being composed of two shaft bodies with different diameters, the periphery of the section of the shaft body with the smaller diameter is provided with threads to be inserted into the threaded hole of the limiting portion 222, the section of the shaft body with the larger diameter may be designed to be the same as the periphery of the limiting portion 222, and the snap hook 223 protrudes from the periphery of the section of the shaft body with the larger diameter, so that the overall periphery size of the snap hook 223 and the shaft body with the larger diameter is definitely larger than the diameter of the first mounting hole 11.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
