The invention provides a ceiling machine. Typically, the ceiling mounted machine is mounted to the ceiling, and thus, in this application, the end of the machine that is closer to the ceiling is defined as up and the end of the machine that is farther from the ceiling is defined as down (as shown in fig. 1).

Referring to fig. 1 to 11, the ceiling machine provided by the invention is provided with a shell 1 and a heat exchanger 2 arranged in the shell 1, wherein the heat exchanger 2 and the shell 1 are enclosed to form an annular air outlet duct 3b.

The cylindrical body 42 is sleeved with the elastic air guide 5, and the elastic air guide 5 is connected with the first positioning ring 43 and the second positioning ring 44 and gradually expands from top to bottom. The lifting mechanism 7 comprises a lifting ring 73 and a driving motor 71 arranged on the lifting ring 73, the lifting ring 73 is sleeved with the cylindrical body 42, the outer diameter of the lifting ring 73 is between the diameter of the upper end edge and the diameter of the lower end edge of the elastic air guide 5, a gear 72 is arranged on the driving motor 71, a rack 77 is arranged on the outer side of the cylindrical body 42 along the axial direction, and the driving motor 71 drives the lifting ring 73 to move up and down through meshing of the gear and the rack.

In this embodiment, the housing 1 has a hollow cylindrical structure. The ceiling fan further comprises a fan 8, the fan 8 is arranged in the shell 1, the heat exchanger 2 is located between the fan 8 and the shell 1, the heat exchanger 2 and the shell 1 enclose to form an air outlet air duct 3b, and one side, close to the fan 8, of the heat exchanger 2 forms an air inlet air duct 3a. Compared with the square air outlet air duct 3b of the existing ceiling fan, the air outlet air duct 3b of the ceiling fan is in annular arrangement, so that on one hand, the air quantity of air outlet can be increased, on the other hand, dead angles of air outlet can be avoided, the air outlet is uniform, and the comfort level of a user is effectively improved.

The width of the second positioning ring 44 may be equal to or greater than the width of the first positioning ring 43, where the width of the first positioning ring 43 refers to a difference between the outer diameter of the first positioning ring 43 and the inner diameter of the first positioning ring 43, and the width of the second positioning ring 44 refers to a difference between the outer diameter of the second positioning ring 44 and the inner diameter of the second positioning ring 44. The elastic wind guide 5 may be connected to the outer edge of the first positioning ring 43 or the second positioning ring 44, and of course, may also be connected to the middle of the first positioning ring 43 or the second positioning ring 44. For example, if the width of the second positioning ring 44 is equal to the width of the first positioning ring 43, the upper end of the elastic air guiding member 5 is connected to the middle of the first positioning ring 43, the lower end of the elastic air guiding member 5 is connected to the outer edge of the second positioning ring 44, and the elastic air guiding member 5 is gradually expanded from top to bottom.

The elastic wind guide 5 is arranged in a conical shape. Specifically, the elastic air guide 5 includes a conical cylindrical body, an upper flange disposed at an upper end of the conical cylindrical body, and a lower flange disposed at a lower end of the conical cylindrical body, wherein the conical cylindrical body is sleeved outside the cylindrical body 42, the upper flange is fastened with the first positioning ring 43, and the lower flange is fastened with the second positioning ring 44. Here, the upper end edge of the elastic air guide 5 refers to the intersection of the tapered tubular body and the upturned edge, and the lower end edge of the elastic air guide 5 refers to the intersection of the tapered tubular body and the upturned edge.

In this embodiment, the elastic wind guide 5 is made of an elastic material, and preferably, the elastic wind guide 5 is an elastic cloth. Specifically, the elastic cloth may be made of spandex. Since the elastic air guide 5 has elasticity and can be elastically deformed to a certain extent, when the lifting ring 73 moves up and down, the elastic air guide 5 can be driven to deform, so that the size of the air outlet duct 3b can be changed. In addition, the elastic wind guide 5 can also play a role in preventing condensation.

The lifting ring 73 is sleeved on the cylindrical body 42, and the lifting ring 73 is located between the cylindrical body 42 and the conical cylindrical body of the elastic air guide 5. The inner diameter of the lifting ring 73 is equal to or larger than the diameter of the cylindrical body 42, and the outer diameter of the lifting ring 73 is between the upper end edge diameter and the lower end edge diameter of the elastic wind guide 5. Therefore, when the lifting ring 73 moves up and down, the elastic air guide 5 can be effectively driven to deform, so as to change the size of the air outlet duct 3b. It will be appreciated that, if the outer diameter of the lifting ring 73 is smaller than the diameter of the upper end edge of the elastic air guide 5, when the lifting ring 73 moves up and down, the elastic air guide 5 cannot be driven to deform, so that the size of the air outlet duct 3b cannot be changed.

In one embodiment, the driving motor 71 may be a stepping motor. As shown in fig. 10 and 11, a gear 72 is provided on the shaft of the driving motor 71, wherein the gear 72 is provided toward one side of the cylindrical body 42. The outer side of the cylindrical body 42 is provided with a rack 77 along the axial direction, wherein the rack 77 may be disposed adjacent to the outer side wall of the cylindrical body 42, or may be disposed at intervals with the outer side wall of the cylindrical body 42, specifically, one end of the rack 77 is connected to the first positioning ring 43, and the other end is connected to the second positioning ring 44, and the rack 77 is disposed corresponding to the gear 72. When the driving motor 71 drives the gear 72 to rotate, the gear 72 is meshed with the rack 77 and moves up and down along the rack 77, thereby driving the lifting ring 73 to move up and down.

According to the technical scheme of the invention, the air guide assembly 4 is arranged at the air outlet of the air outlet duct 3b, wherein the air guide assembly 4 comprises a fixed bracket 41 and an annular elastic air guide member 5, the fixed bracket 41 comprises a cylindrical body 42, a first positioning ring 43 formed by laterally protruding the upper end of the cylindrical body 42, and a second positioning ring 44 formed by laterally protruding the lower end of the cylindrical body, the cylindrical body 42 is sleeved with the elastic air guide member 5, the elastic air guide member 5 is connected with the first positioning ring 43 and the second positioning ring 44 and gradually expands from top to bottom, the cylindrical body 42 is sleeved with the lifting ring 73, and the driving motor 71 is meshed with the lifting ring 73 through a gear 72 rack 77 so as to deform the elastic air guide member 5, thereby changing the shape of the air outlet duct 3b.

In this embodiment, the ceiling fan further includes a water pan 6, the water pan 6 is disposed at the lower end of the heat exchanger 2, and the fixing bracket 41 is mounted on the water pan 6. The water receiving disc 6 can enable condensed water on the heat exchanger 2 to flow out in time so as to ensure the heat exchange efficiency of the heat exchanger 2.

In a preferred embodiment, the width of the second positioning ring 44 is greater than that of the first positioning ring 43, and the elastic air guide 5 is connected to the outer edge of the first positioning ring 43 and the outer edge of the second positioning ring 44, so that the elastic air guide 5 is convenient to mount and dismount. Specifically, the air guide assembly 4 further includes a retainer 45, and the retainer 45 includes a first collar 451 and a second collar 452 (as shown in fig. 4). The first collar 451 is disposed on the outer periphery of the first positioning ring 43, the second collar 452 is disposed on the outer periphery of the second positioning ring 44, the upper end of the elastic air guide 5 is clamped between the first positioning ring 43 and the first clamping portion 451, and the lower end of the elastic air guide 5 is clamped between the second positioning ring 44 and the second clamping portion 452. Wherein, the first collar 451 and the second collar 452 may be magnetic rings.

Further, the lifting mechanism 7 further includes a snap ring 76 disposed at the periphery of the lifting ring 73, and the elastic air guide 5 is clamped between the snap ring 76 and the lifting ring 73. Here, the snap ring 76 may be connected to the lift ring 73 in various manners, for example, the snap ring 76 may be connected to the lift ring 73 by a magnet. Of course, the snap ring 76 may be a magnetic ring, and the magnetic ring is attached to the periphery of the lifting ring 73. Because the snap ring 76 cooperates with the lifting ring 73 to clamp the elastic air guide 5, when the lifting ring 73 moves up and down, the elastic air guide 5 can be effectively driven to deform, so that the shape of the air outlet duct 3b is changed.

Referring to fig. 3 and 4, in order to increase the strength of the lifting ring 73, an inner ring 74 and a connecting portion 75 connecting the inner ring 74 and the lifting ring 73 may be provided inside the lifting ring 73. The connection portion 75 may be a connection rod, a connection block, or a connection plate.

In one embodiment, the drive motor 71 may be mounted to the inner ring 74. Of course, in another embodiment, the inner ring 74 may be recessed toward the connecting portion 75 to form a mounting groove 741, and the driving motor 71 is mounted in the mounting groove 741, so that on one hand, the mounting stability of the driving motor 71 may be improved, and on the other hand, the space for mounting the driving motor 71 may be saved.

Preferably, three mounting grooves 741 are uniformly formed in the inner ring 74, the number of the driving motors 71 is three, each driving motor 71 is correspondingly mounted in one mounting groove 741, and each driving motor 71 is provided with a gear. It can be appreciated that the three driving motors 71 may be operated independently or simultaneously, so that on one hand, the service life of the driving motors 71 can be prolonged, and further, the service life of the ceiling machine can be prolonged, thereby reducing the probability of replacing and maintaining the ceiling machine; on the other hand, the lifting ring 73 can be ensured to move up and down smoothly, which is beneficial to driving the elastic air guide 5 to deform uniformly, thereby being beneficial to uniform air outlet of the annular air outlet duct 3b.

Further, an annular outer edge panel 84 is disposed at the lower end of the housing, and the inner holes of the outer edge panel 84 are gradually widened from top to bottom. The outer edge panel 84 and the elastic air guide 5 enclose to form an air outlet of the air outlet duct 3b, and the outer edge panel 84 can further extend the effect of the air outlet duct 3b, and at the same time, also can play an attractive role.

In this embodiment, the ceiling fan further includes an air guide ring 81, a heat insulation layer 82, and an air inlet grille 83. The air guide ring 81 is arranged corresponding to the air inlet of the air inlet duct 3a and is positioned above the fan 8, and the air guide ring 81 can guide fresh air to enter the air inlet duct more stably and accurately.

The heat preservation 82 is installed on the water pan 6, and the heat preservation 82 is sleeved in the air guide assembly 4, specifically, the heat preservation 82 is sleeved in the cylinder body, and the heat preservation 82 can be made of foam materials or cotton fabric materials. The heat-insulating layer 82 can insulate the heat-exchanged gas, and prevent the heat-exchanged gas from directly exchanging heat with the gas outside the housing 1. The air inlet grille 83 is mounted at the lower end of the air guide assembly 4, and specifically, the air inlet grille 83 is connected to the second positioning ring 44.

When the ceiling machine is used, the lifting ring 73 is driven to move up and down by the driving motor 71, and the lifting ring 73 drives the elastic air guide 5 to deform, so that the shape of an air outlet of the air outlet duct can be changed, and the concrete steps are as follows:

referring to fig. 6, when the driving motor 71 drives the lifting ring 73 to move to the first position (the lowest end), the lifting ring 73 drives the elastic air guide 5 to deform, so that the air outlet of the air guide channel is enlarged and then reduced, and thus the air after heat exchange by the heat exchanger 2 can form a buffer at the air outlet of the air outlet duct 3b, thereby realizing uniform air supply at a horizontal angle and improving comfort level of users.

Referring to fig. 7, when the driving motor 71 drives the lifting ring 73 to move to the second position, the elastic air guide 5 is not deformed, and the shape of the air outlet of the air guide channel is unchanged, at this time, a longer and more stable air outlet of the air outlet duct 3b can be formed, so that the air after heat exchange by the heat exchanger 2 can be sent to a longer distance.

Referring to fig. 8, when the driving motor 71 drives the lifting ring 73 to move to the third position, the lifting ring 73 drives the elastic air guide 5 to deform, so that the air outlet of the air guide channel is first reduced and then enlarged, and air supply in a large angle range can be realized. Specifically, the air after heat exchange by the heat exchanger 2 increases the air speed at the reduced part of the air outlet of the air guide duct and increases the air supply range at the enlarged part of the air outlet of the air guide duct, thereby realizing the air supply in a large angle range.

Referring to fig. 9, when the driving motor 71 drives the lifting ring 73 to move to the fourth position (uppermost end), the lifting ring 73 drives the elastic air guide 5 to deform, so that the air outlet of the air outlet duct 3b is closed, and thus, dust and other substances can be prevented from entering the ceiling machine.

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