Typically, the ceiling mounted machine is mounted to the ceiling, and in the present application, the side of the ceiling mounted machine that is closer to the ceiling is defined as the upper side, and the side of the ceiling mounted machine that is farther from the ceiling is defined as the lower side.

As shown in fig. 1 to 7, the ceiling machine according to the present application includes a panel assembly 100 and a water pan 200, wherein the panel assembly 100 has an air inlet, and an air outlet 101 annularly disposed at the periphery of the air inlet, and an air inlet grille 130 is disposed at the air inlet. The ceiling fan also comprises a flexible air duct 300 and a driving device. The flexible air duct 300 is installed between the air inlet grille 130 and the water pan 200 and is arranged close to the air outlet 101, the flexible air duct 300 is gradually expanded from top to bottom, the flexible air duct 300 comprises a first pleat ring 310 and a second pleat ring 320 which are arranged in a cylindrical shape and can stretch up and down, and the first pleat ring 310 is positioned above the second pleat ring 320. The driving means is connected to the first pleat ring 310 and/or the second pleat ring 320 to drive the first pleat ring 310 and/or the second pleat ring 320 to extend or retract at least partially in the up-down direction.

In particular, the ceiling machine has a housing, which may be square, circular or oval in shape. A heat exchanger and a wind wheel assembly are arranged in the shell, wherein the water pan 200 is arranged at the lower end of the heat exchanger. The panel assembly 100 is installed on the lower surface of the casing, an air inlet is formed in the middle of the panel assembly 100, the air inlet grille 130 is installed at the air inlet, the panel assembly 100 is further provided with an air outlet 101 located at the periphery of the air inlet, and thus indoor air enters the ceiling machine from the air inlet and exchanges heat with the heat exchanger, and is sent out from the air outlet 101. The shape of the air inlet may be various, for example, circular, elliptical or square, and is not particularly limited herein.

In the present embodiment, as shown in fig. 1 and 2, the panel assembly 100 includes an outer panel 110 and a partition 120 that are annularly disposed. The partition board 120 is sleeved in the outer panel 110, and an outer side wall of the partition board 120 is tightly attached to an inner side wall of the outer panel 110, wherein a lower end of the partition board 120 is gradually widened from top to bottom. The flexible air duct 300 is mounted on the inner side of the partition board 120, and forms an annular air outlet 101 with the inner side wall of the partition board 120. The flexible air duct 300 includes a first pleat ring 310 and a second pleat ring 320 that are disposed in a tubular shape, where the first pleat ring 310 and the second pleat ring 320 may be disposed in an integral molding manner, or may be formed by splicing a plurality of arc segments along a circumferential direction. If the first pleat rings 310 and the second pleat rings 320 are formed by splicing a plurality of arc segments along the circumferential direction, the annular air outlet 101 may be divided into a plurality of air outlet areas, and the air supply angle of each air outlet area may be independently controlled, so as to satisfy the differentiated requirements of users.

The flexible air duct 300 is gradually expanded from top to bottom, and comprises a first pleat ring 310 and a second pleat ring 320 which can be stretched up and down, wherein the first pleat ring 310 is positioned above the second pleat ring 320, and the lower end of the first pleat ring 310 is connected with the upper end of the second pleat ring 320. Specifically, the first pleat ring 310 and the second pleat ring 320 may be inflatable pleat rings, which stretch if inflated into the interior cavity of the inflatable pleat ring; if the air in the inner cavity of the inflatable pleat ring is pumped away, the inflatable pleat ring is contracted. Of course, the first pleat ring 310 and the second pleat ring 320 may be configured as a stretchable pleat structure that contracts when subjected to a compressive force and expands when subjected to a tensile force.

The driving means may be connected to the first pleat ring 310 or may be connected to the second pleat ring 320, of course, the driving means may also be connected to both the first pleat ring 310 and the second pleat ring 320. For example, if the driving device is connected to the first pleat ring 310 and the second pleat ring 320 at the same time, the driving device may drive the first pleat ring 310 to extend downward and simultaneously drive the second pleat ring 320 to retract downward; alternatively, the driving means drives the second pleat rings 320 to extend upward while driving the first pleat rings 310 to retract upward. Thus, the shape of the air outlet 101 can be changed, and the purpose of changing the air supply angle can be achieved.

It should be noted that, the driving device drives the first pleat ring 310 and/or the second pleat ring 320 to extend or retract at least partially in the up-down direction means that the driving device may drive the first pleat ring 310 and/or the second pleat ring 320 to extend or retract in the up-down direction as a whole, and may also drive the first pleat ring 310 and/or the second pleat ring 320 to extend or retract partially in the up-down direction. For example, the driving device may drive one of the arcuate segments of the first pleat ring 310 to extend or retract in the up-down direction, and a portion of the arcuate segment of the second pleat ring 320 corresponding to the arcuate segment may also extend or retract in the up-down direction, so that the air supply angle of the air outlet area corresponding to the arcuate segment may be changed.

The ceiling machine adopts the flexible air duct 300, wherein the flexible air duct 300 is gradually expanded from top to bottom, the flexible air duct 300 comprises a first pleat ring 310 and a second pleat ring 320 which are arranged in a cylindrical shape and can stretch up and down, and the first pleat ring 310 is positioned above the second pleat ring 320; the driving device is connected to the first pleat ring 310 and/or the second pleat ring 320 to drive the first pleat ring 310 and/or the second pleat ring 320 to extend or retract along the up-down direction, so as to change the shape of the air outlet 101, thereby achieving the purpose of changing the air supply angle.

In a preferred embodiment, the first pleat ring 310 is formed by sequentially splicing a plurality of first arc segments 311 from beginning to end along the same circumference, the second pleat ring 320 is formed by sequentially splicing a plurality of second arc segments 321 from beginning to end along the same circumference, and the first arc segments 311 and the second arc segments 321 are arranged in a one-to-one correspondence in the up-down direction. The driving device comprises a plurality of driving components, and each driving component is connected with a corresponding first arc-shaped section 311 and/or second arc-shaped section 321 so as to drive the first arc-shaped section 311 and/or the second arc-shaped section 321 to extend or retract along the up-down direction.

It should be noted that, the air outlet 101 includes a plurality of air outlet areas, each air outlet area corresponds to a group of first arc segments 311 and second arc segments 321 which are correspondingly arranged in the up-down direction, and the air supply angle of the corresponding air outlet area can be changed by the first arc segments 311 and the second arc segments 321 of the group being mutually matched. Because each driving assembly can independently control the corresponding first arc-shaped section 311 and second arc-shaped section 321, the air supply angles of the air outlet areas can be the same or different. Preferably, the number of the first arc segments 311 is 2 to 5, and the number of the second arc segments 321 is 2 to 5.

In this embodiment, each driving assembly is connected to a corresponding one of the first arc segments 311, so as to drive the first arc segments 311 to extend or retract in an up-down direction.

Referring to fig. 7 to 9, the first arc-shaped section 311 is of a hollow structure, the driving assembly includes an air pump 400 and an air pipe 410, an air inlet and an air outlet 411 are provided on the air pipe 410, the first arc-shaped section 311 is provided with an air inlet pipe 412 communicated with the air outlet 411, and the air pump 400 is communicated with the air inlet to drive the first arc-shaped section 311 to extend or retract along the up-down direction. It will be appreciated that in order to better control the speed at which the first arcuate segment 311 expands or contracts in the up-down direction, a resilient return member, such as a spring, silicone, or the like, may be provided within the first arcuate segment 311.

Further, the second arc-shaped section 321 is of a hollow structure, and the second arc-shaped section 321 is provided with a plurality of ventilation holes 322. When the air pump 400 inflates the first arc-shaped section 311 through the air inlet pipe 412, the first arc-shaped section 311 extends downward, and at the same time, the corresponding second arc-shaped section 321 is contracted downward due to the downward pressing force of the first arc-shaped section 311, and the air in the second arc-shaped section 321 flows out from the air vent 322. When the air pump 400 pumps air to the first arc-shaped section 311 through the air pipe 410, the first arc-shaped section 311 is contracted upwards, and meanwhile, the corresponding second arc-shaped section 321 is stretched upwards due to the upward tensile force of the first arc-shaped section 311. In this way, the shape of the air outlet 101 can be changed and the air supply angle can be changed by the cooperation of the first arc segment 311 and the corresponding second arc segment 321.

Referring to fig. 4 and 7, the driving assembly further includes a lifting frame 420, and the lifting frame 420 is disposed between the first arc-shaped section 311 and the corresponding second arc-shaped section 321, and connects the first arc-shaped section 311 and the second arc-shaped section 321.

In one embodiment, the driving assembly may drive the first arc-shaped section 311 and the second arc-shaped section 321 to extend or retract up and down by controlling the lifting frame 420 to move up and down. Specifically, the driving assembly includes a driving motor connected to the lifting frame 420 to drive the lifting frame 420 to move up and down. The driving motor drives the lifting frame 420 to move up and down in various manners, for example, the driving motor can drive the lifting frame 420 to move up and down through a driving belt, can drive the lifting frame 420 to move up and down through a gear-rack meshing manner, and can drive the lifting frame 420 to move up and down through a cam mechanism, which is not particularly limited.

When the driving motor drives the lifting frame 420 to move upwards, the first pleat rings 310 are contracted upwards by the upward extrusion force of the lifting frame 420, and at the same time, the second pleat rings 320 are extended upwards by the upward tension force of the lifting frame 420; when the driving motor drives the elevation frame 420 to move downward, the first pleat rings 310 are extended downward by the downward pulling force of the elevation frame 420, and at the same time, the second pleat rings 320 are contracted downward by the downward pressing force of the elevation frame 420.

With continued reference to fig. 7, the ceiling apparatus further includes a limiting plate 430 mounted between the water pan 200 and the air inlet grille 130, the limiting plate 430 is provided with a chute 431 extending vertically, the lifting frame 420 is provided with a guide post 421, and the guide post 421 is slidably mounted in the chute 431. It will be appreciated that the slide groove 431 serves to guide the lifting frame 420. Preferably, limiting plates 430 are disposed at both ends of the lifting frame 420.

Further, referring to fig. 2, 3 and 4, the panel assembly 100 further includes a mounting frame 140, and the mounting frame 140 is disposed inside the flexible air duct 300. The mounting frame has the functions of fixing the flexible air duct 300 and preventing wind from flowing to the air outlet 101 through the flexible air duct 300.

It will be appreciated that in another embodiment, the driving device may be further connected to the first pleat ring 310 to drive the first pleat ring 310 to extend or retract in an up-down direction. The manner in which the driving device drives the first pleat ring 310 to extend or retract up and down is referred to the above embodiment, and will not be described herein.

When the ceiling machine of the present application is used, the shape of the air outlet 101 is changed by driving the first pleat ring 310 and the second pleat ring 320 to extend and retract up and down, and the air supply angle is changed as follows:

referring to fig. 3, when the lifting frame 420 moves to the first position, the shape of the air outlet 101 is unchanged, and at this time, a longer and more stable air outlet 101 can be formed, so that the air after heat exchange by the heat exchanger can be sent to a longer distance.

Referring to fig. 5, when the lifter 420 moves to the second position, the air outlet 101 has a shape that is reduced and enlarged, so that air can be blown over a wide range of angles. Specifically, the air flow rate of the air after heat exchange by the heat exchanger is increased at the reduced part of the air outlet 101, and the air supply range is increased at the enlarged part of the air outlet 101, thereby realizing air supply in a large angle range.

Referring to fig. 6, when the lifting frame 420 moves to the third position, the air outlet 101 is in a shape that is enlarged and then reduced, so that the air after heat exchange by the heat exchanger can form a buffer at the air outlet 101, thereby realizing uniform air supply at a horizontal angle and improving comfort level of users.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the scope of the application, and all equivalent structural changes made by the description of the present application and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the application.
