As shown in fig. 1 to 5, the hanging type air conditioning indoor unit includes a casing 100, and the casing 100 is used for accommodating and carrying other components of the hanging type air conditioning indoor unit, such as an evaporator, a fan, an air deflector 200, and the like. The housing 100 includes a front wall 130 of the housing 100, a rear wall 140 of the housing 100, and side walls 150 of the housing 100, in the present embodiment, the front wall 130 of the housing 100 and the rear wall 140 of the housing 100 are disposed opposite to each other in the front-rear direction, and the side walls 150 of the housing 100 are located on the left and right sides of the front wall 130 of the housing 100. The rear wall 140 of the housing 100 and the side walls 150 of the housing 100 are flat, and the front wall 130 of the housing 100 is semicircular arc-shaped. In the present embodiment, the bottom of the front wall 130 of the casing 100 is provided with the air outlet 110, the air outlet 110 is opened from the left side to the right side of the front wall 130 of the casing 100, and the shape of the air outlet 110 is a long strip. Fig. 1 is a schematic view of the outlet 110 in a closed state, and fig. 2 and 3 are schematic views of the outlet 110 in an open state. Fig. 4 and 5 are schematic views of the outlet 110 in an open state according to another embodiment.

As shown in fig. 1 to 5, the hanging type air conditioning indoor unit further includes an air deflector 200, and the air deflector 200 includes a plate body 210 and two supporting arms 220. The plate body 210 is disposed at the air outlet 110, and is used for opening and closing the air outlet 110; two support arms 220 extend from both ends of the plate 210 toward the rear wall 140 of the housing 100, respectively. As shown in fig. 1, when the hanging type air conditioning indoor unit is in a non-operating state, the plate 210 covers the air outlet 110 to prevent external dust from falling into the hanging type air conditioning indoor unit. As shown in fig. 2 to 5, when the hanging type air conditioning indoor unit is in an operating state, the plate 210 is displaced relative to the casing 100 to open the air outlet 110. The support arms 220 extend toward the rear wall 140 of the housing 100 to allow the plate 210 to have a margin for forward movement relative to the housing 100.

The hanging type air conditioner indoor unit further includes a driving assembly 300, and the driving assembly 300 includes a motor 310, a swing arm 320, and a shaft assembly 330. The motor 310 is disposed at the sidewall 150 of the housing 100. The swing arm 320 has a long hole 321 formed along a longitudinal direction thereof, and an end thereof is connected to an output shaft of the motor 310 and is driven by the motor 310 to rotate. The shaft assembly 330 includes a rotating shaft 331, and a first end of the rotating shaft 331 is fixed to an end of the supporting arm 220 away from the board 210, that is, a first end of the rotating shaft 331 is fixed to an end of the supporting arm 220, which is an end away from the board 210. The second end of the rotating shaft 331 is received in the elongated hole 321 for moving along the elongated hole 321; with the rotation of the swing arm 320, the rotation shaft 331 drives the air deflector 200 to open and close the air outlet 110.

Therefore, the second end of the rotating shaft 331 is received in the elongated hole 321, and the rotating shaft 331 can move along the elongated hole 321, so that the rotating shaft 331 can rotate and move back and forth relative to the housing 100. The first end of the rotation shaft 331 is fixed to the end of the support arm 220, and the support arm 220 is fixed to the board 210, so that the board 210 can move forward and rotate relative to the housing 100. When the plate 210 rotates, the plate 210 can move forward and backward relative to the casing 100, and move forward or backward relative to the casing 100 to get rid of the structural interference of the casing 100 on the air deflector 200, so as to avoid the influence of the casing 100 on the rotation angle of the air deflector 200, and enable the rotation of the air deflector 200 to be more flexible.

As shown in fig. 2 to 3, the plate body 210 moves forward and upward relative to the housing 100 to open the outlet 110, as shown in fig. 4 to 5, the plate body 210 moves forward and downward relative to the housing 100 to open the outlet 110, and the movement of the plate body 210 to open the outlet 110 is not limited in detail in the present embodiment.

For example, as shown in fig. 2 to 3, the second end of the rotating shaft 331 is received in the elongated hole 321 and can move along the elongated hole 321, so that when the swing arm 320 rotates clockwise, the rotating shaft 331 moves to the front side and the upper side; when the swing arm 320 rotates counterclockwise, the rotation shaft 331 moves to the rear side and to the lower side. The first end of the rotation shaft 331 is fixed to an end of the support arm 220 far from the board body 210, so that the board body 210 can be moved to the front and upper sides when the rotation shaft 331 is moved to the front and upper sides. When the rotation shaft 331 moves to the rear side and the lower side, the plate body 210 can also move to the lower side and the rear side. In the above embodiment, the manner in which the plate body 210 closes and opens the outlet port 110 is merely exemplary and not exclusive, as the plate body 210 opens the outlet port 110 when moving forward to the upper side and closes the outlet port 110 when moving backward to the lower side. As shown in fig. 4 to 5, a specific example in which the plate body 210 is moved forward and downward relative to the housing 100 to open the outlet 110 is specifically described in the following embodiments.

As shown in fig. 1, 2, 4, and 7, in some embodiments, the motor 310 and the swing arm 320 are located outside of the housing 100, i.e., the motor 310 and the swing arm 320 are located outside of the cavity formed by the housing 100. The sidewall 150 of the housing 100 is formed with a limiting hole 120, and the second end of the rotating shaft 331 passes through the limiting hole 120 and is received in the elongated hole 321. The shape of the limiting hole 120 may be set according to the requirement, and is not limited herein. The motor 310 and the swing arm 320 are located outside the casing 100 to save the space of the air conditioner.

In some embodiments, as shown in fig. 1, 4, 10 and 11, the side wall 150 of the housing 100 is provided with a rack 160 from front to back, and the extending direction of the limiting hole 120 is identical to the extending direction of the rack 160. That is, the limiting hole 120 extends from the front to the rear of the side wall 150 of the housing 100 as shown in the drawings, or it can be understood that the limiting hole 120 is provided from the front of the side wall 150 of the housing 100 to the rear. The rack 160 also extends rearward from the front of the side wall 150 of the housing 100. The shaft assembly 330 includes a gear 334, the gear 334 is sleeved on the first end of the rotating shaft 331; gear 334 meshes with rack 160.

In the present embodiment, as shown in fig. 4 to 6, when the swing arm 320 rotates clockwise, the rotation shaft 331 and the gear 334 move to the front side and rotate to the lower side at the same time, and the plate body 210 also moves to the lower side and the front side to open the air outlet 110. When the swing arm 320 rotates counterclockwise, the rotation shaft 331 and the gear 334 move to the rear side and rotate to the upper side, and the plate body 210 also moves to the upper side and the rear side to close the air outlet 110. Therefore, the gear 334, the rack 160 and the limiting hole 120 cooperate with each other to change the direction in which the air outlet 110 is opened and closed by the plate body 210. The gear 334, the rack 160 and the limiting hole 120 cooperate with each other to control the moving direction, the moving amplitude, etc. of the plate body 210 more precisely.

In some embodiments, as shown in fig. 8-11, the rack 160 is located below the retaining hole 120; as shown in fig. 4, the motor 310 is located obliquely above the stopper hole 120. The side wall 150 of the housing 100 has a large number of blank areas above, and the motor 310 is located obliquely above the position-limiting hole 120 to facilitate the arrangement of the motor 310, and the selectable position is relatively wide. The rack 160 is located below the limiting hole 120, and can support the air deflector 200 to a certain extent through the gear 334, which is helpful for the air deflector 200 to be more stable in the rotating process.

In some embodiments, as shown in FIG. 11, rack 160 is angled slightly upward from the front to the back of side wall 150. The rack 160 is inclined upward, which helps to increase the movement range of the plate body 210 in the process of opening and closing the outlet 110. Whether or not the rack 160 is inclined and the angle of inclination are not particularly limited and may be selected according to specific needs.

In some embodiments, as shown in fig. 1-11, the limiting hole 120 and the elongated hole 321 always intersect during the rotation of the swing arm 320. That is, when the rotation shaft 331 moves to one end of the stopper hole 120, the rotation shaft 331 is at one end of the elongated hole 321, or is in the elongated hole 321 and can move along the elongated hole 321. When the rotation shaft 331 moves to the other end of the limiting hole 120, the rotation shaft 331 is at the other end of the elongated hole 321, or is in the elongated hole 321 and can move along the elongated hole 321. For convenience of description, an end of the stopper hole 120 close to the rear wall 140 of the housing 100 is referred to as a rear end of the stopper hole 120, and an end of the stopper hole 120 close to the front wall 130 of the housing 100 is referred to as a front end of the stopper hole 120; an end of the elongated hole 321 close to the motor 310 is referred to as an upper end of the elongated hole 321, and an end of the elongated hole 321 far from the motor 310 is referred to as a lower end of the elongated hole 321. The limiting hole 120 and the elongated hole 321 are crossed all the time, it can also be understood that when the rotating shaft 331 moves to the rear end of the limiting hole 120, the rotating shaft 331 is located at the upper end of the elongated hole 321, or has a certain distance from the upper end of the elongated hole 321; when the rotating shaft 331 moves to the front end of the limiting hole 120, the rotating shaft 331 is located at the lower end of the elongated hole, or has a certain distance from the lower end of the elongated hole 321, so as to satisfy the sufficient moving space of the rotating shaft 331. The limiting hole 120 and the elongated hole 321 are always crossed to provide a sufficient movement space for the rotation shaft 331.

In some embodiments, as shown in fig. 7 and 8, the shaft assembly 330 includes a first shaft sleeve 332 and a second shaft sleeve 333, the first shaft sleeve 332 and the second shaft sleeve 333 are sequentially disposed at a second end of the rotating shaft 331, the first shaft sleeve 332 is received in the limiting hole 120, the second shaft sleeve 333 is received in the elongated hole 321, and an outer diameter of the second shaft sleeve 333 is greater than an outer diameter of the first shaft sleeve 332. The outer diameter of the second bushing 333 is larger than that of the first bushing 332 to prevent the shaft from moving left and right with respect to the sidewall 150 of the housing 100 during the movement, that is, to prevent the rotation shaft 331 from moving toward the inside of the housing 100 or the outside of the housing 100, so as to precisely control the rotation of the plate body 210.

In some embodiments, as shown in fig. 1-5, the curvature of the housing 100 above and below the adjacent outlet 110 is adapted to the curvature of the air deflector. The radians of the shell 100 above and below the adjacent air outlet 110 are matched with the radians of the air deflectors so as to meet the requirement that the air deflectors can move along the shell 100 in the process of opening and closing the air outlet 110, thus saving space and being more attractive.

In some embodiments, as shown in fig. 7, two driving assemblies 300 are symmetrically disposed at two ends of the wind guide plate 200, and respectively connected to the wind guide plate 200 to drive the wind guide plate 200 to rotate. The matching relationship of the driving assembly 300 and the assembling manner of the side wall 150 of the housing 100 are the same as the above embodiments, and are not described herein again.

According to a second aspect of the present invention, there is also provided an air conditioner including an outdoor unit and a wall-hung indoor unit of an air conditioner as described in any one of the above embodiments. Since the air conditioner comprises the hanging type air conditioner indoor unit of any one of the embodiments, the technical effects of the hanging type air conditioner indoor unit are achieved, and the details are not repeated.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
