[0027] Wherein, a cavity is defined inside the inner casing 110 , and a preset number of first air outlet holes 111 are opened on the inner casing 110 . The outer shell 120 is disposed outside the inner shell 110 , and the second air outlet hole 121 corresponding to the position of the first air outlet hole 111 is opened on the outer shell 120 . In a preferred embodiment, both the inner casing 110 and the outer casing 120 are cylindrical. The number and shape of the first air outlet holes 111 and the second air outlet holes 121 are set correspondingly.
[0028] Specifically, such as Figure 1 to Figure 4 As shown, the first air outlet 111 and the second air outlet 121 can be arranged in a flower shape, so as to improve the overall aesthetics of the indoor unit 100 of the ceiling-mounted air conditioner. The number of the first air outlet 111 and the second air outlet 121 can be set to 39, and they are evenly arranged in a row of three, a total of 13 rows, so that the indoor unit 100 of the ceiling type air conditioner can blow air. Even air supply in upper, middle, lower and circumferential directions. It should be noted that the specific numbers and specific shapes of the above-mentioned first air outlet holes 111 and second air outlet holes 121 are only examples, rather than limiting the present invention. In some other embodiments, the first air outlet holes 111 and the second air outlet holes 121 can also be set in other numbers and shapes.
[0029] The rotation driving mechanism is disposed on the inner housing 110 and is configured to drive the outer housing 120 to rotate so that the area of the overlapping portion of the first air outlet 111 and the second air outlet 121 changes. The centrifugal blower 130 is disposed inside the cavity and is configured to make the air entering the cavity form wind and blow out through the overlapped part. Wherein, the area of the overlapping portion of the first air outlet 111 and the second air outlet 121 is the largest, that is, when the first air outlet 111 and the second air outlet 121 completely overlap, the air output is the largest. When the overlapping area of the first air outlet hole and the second air outlet hole 121 is the smallest, that is, when the first air outlet hole 111 and the second air outlet hole 121 do not overlap at all, the air output is the smallest, and it can be considered that there is almost no wind.
[0030] In the indoor unit 100 of the ceiling-mounted air conditioner of this embodiment, air is discharged through the overlapped portion of the first air outlet 111 of the inner housing 110 and the second air outlet 121 of the outer housing 120, which can realize uniform air outlet in the circumferential direction and expand the air volume. The air supply angle and range enable the room to achieve rapid and balanced temperature adjustment, and avoid the user's discomfort caused by the small-scale blowing of the airflow, effectively improving the user's experience.
[0031] like image 3 and Figure 4 As shown, the bottom of the inner housing 110 is provided with a first bracket 140 , and the bottom of the outer housing 120 is provided with a second bracket 150 . And the rotation drive mechanism includes: a rotation motor (not shown in the figure), fixed on the first support 140, and its rotation shaft is connected with the second support 150, so that the outer casing 120 is driven to rotate through the rotation shaft after opening. In fact, the bottom of the outer casing 120 is lower than the bottom of the inner casing 110, so that the second bracket 150 is below the first bracket 140, so that the top of the rotating motor can be fixed with the first bracket 140, and the bottom of the rotating motor can be fixed. The axis of rotation is fixed to the second bracket 150. Preferably, the rotating motor can be a stepping motor.
[0032]The first bracket 140 includes: a plurality of first spokes 141 and a first hub plate 142 . Wherein, a plurality of first spokes 141 respectively extend from the bottom end of the inner housing 110 to the center of the inner housing 110 . The first hub plate 142 is disposed at the center of the inner shell 110 and connected to a plurality of first spokes 141 , and the rotating motor is fixed on the first hub plate 142 . The second bracket 150 includes: a plurality of second spokes 151 and a second hub plate 152 . Wherein, a plurality of second spokes 151 respectively extend from the bottom end of the outer shell 120 to the center of the outer shell 120 . The second hub plate 152 is disposed at the center of the outer shell 120 and connected to a plurality of second spokes 151 , and the rotation axis is fixed on the second hub plate 152 . It should be noted that the plurality of first spokes 141 and the plurality of second spokes 151 are uniformly distributed.
[0033] In a specific embodiment, for example image 3 and Figure 4 As shown, there are three first spokes 141 and three second spokes 151, and the included angle between any two of the three first spokes 141 is 120°; the included angle between any two of the three second spokes 151 is 120° . The first hub plate 142 and the second hub plate 152 may also be provided with holes for fixing the top of the rotating motor and the rotating shaft, especially the holes for fixing the rotating shaft on the second hub plate 152 match the cross-sectional shape of the rotating shaft set up.
[0034] like figure 1 and image 3 As shown, the outer peripheral wall of the inner housing 110 is provided with an inner ring 112 , and the outer housing 120 is provided with an outer ring 122 matched with the inner ring 112 , so that the outer housing 120 is disposed outside the inner housing 110 . Preferably, the inner ring 112 is disposed on the upper half of the outer peripheral wall of the inner casing 110 , and the top end of the outer casing 120 is turned inward to form the outer ring 122 . Moreover, the inner ring 112 can actually be a raceway structure, and the inner ring 112 and the outer ring 122 cooperate in a form similar to a rolling bearing, so that the outer shell 120 can be arranged outside the inner shell 110, and The resistance when the rotation driving mechanism drives the outer casing 120 to rotate can be effectively reduced.
[0035] Through the relative movement between the outer shell 120 and the inner shell 110, the area of the overlapped part of the first air outlet hole 111 and the second air outlet hole 121 is changed, and the air volume can be effectively adjusted so that the air volume meets the user's demand. match. In a preferred embodiment, the rotation driving mechanism is further configured to: drive the outer casing 120 to rotate, so that the area of the overlapping portion is proportional to the size of the air outlet gear of the indoor unit 100 of the ceiling-type air conditioner. That is to say, the larger the air outlet gear, the larger the area of the overlapping portion of the first air outlet 111 and the second air outlet 121; The area of the overlapping portion of the air outlet holes 121 is smaller.
[0036] like Figure 5 and Image 6 As shown, the ceiling-mounted air conditioner indoor unit 100 may further include: an air intake grill 160 and an evaporator 170 . Wherein, the air intake grille 160 is disposed at the bottom of the outer casing 120, and is provided with a plurality of air intakes 161 to allow external air to enter the cavity. The evaporator 170 is disposed outside the periphery of the centrifugal fan 130 and arranged to exchange heat with the wind generated by the centrifugal fan 130 . Specifically, the shape of the evaporator 170 is matched with the shapes of the inner shell 110 and the outer shell 120 so that the wind after heat exchange passes through the overlapping parts of the first air outlet hole 111 and the second air outlet hole 121 in the circumferential direction evenly. send out.
[0037] In addition, the centrifugal fan 130 may include a centrifugal motor 131 and a centrifugal fan 132 , and the centrifugal motor 131 is disposed on the top of the centrifugal fan 132 and is configured to drive the centrifugal fan 132 to rotate. The indoor unit 100 of the ceiling-mounted air conditioner may further include: a top plate 180 , which is covered on the top of the inner casing 110 and fixed to the ceiling of the room. The centrifugal motor 131 may be fixed on the top plate 180 .
[0038] In the indoor unit 100 of the ceiling-mounted air conditioner of this embodiment, air is discharged through the overlapped portion of the first air outlet 111 of the inner housing 110 and the second air outlet 121 of the outer housing 120, which can realize uniform air outlet in the circumferential direction and expand the air volume. The air supply angle and range enable the room to achieve rapid and balanced temperature adjustment, and avoid the user's discomfort caused by the small-scale blowing of the airflow, effectively improving the user's experience.
[0039] Furthermore, in the indoor unit 100 of the ceiling-mounted air conditioner of this embodiment, through the relative movement between the outer shell 120 and the inner shell 110, the area of the overlapping portion of the first air outlet 111 and the second air outlet 121 can be changed.
