DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The present invention will be further described below in conjunction with embodiments, but it is not limited to the content in the specification.

[0036] As Figure 1 shown, the present invention discloses a ceiling machine panel assembly, including a return air panel 10 and a moving part 20. The return air panel 10 has a return air opening 11; the moving part 20 is movably arranged on the return air panel 10. The moving part 20 has a return air area 21 and a shielding area 22, and the moving part 20 has an open position and a closed position; in the open position of the moving part 20, the return air area 21 covers the return air opening 11 to open the return air opening 11; in the closed position of the moving part 20, the shielding area 22 covers the return air opening 11 to close the return air opening 11. The ceiling machine panel assembly of the present invention is provided with a movable moving part 20, and the moving part 20 has a return air area 21 and a shielding area 22. When the return air area 21 covers the position of the return air opening 11, the return air opening 11 can be opened for return air; when the shielding area 22 covers the position of the return air opening 11, the return air opening 11 can be closed. In use, the moving part 20 can control the opening or closing of the return air opening 11 by moving, so that the return air opening 11 is opened when the ceiling machine is in use and closed when the machine is stopped, improving the overall appearance integrity, and can prevent dust from falling and insects from entering the equipment interior, improving reliability.

[0037] In the first embodiment, the moving part 20 includes a bracket 23 and a closing plate 24. The bracket 23 is movably arranged on the return air panel 10; the closing plate 24 is connected to the bracket 23, and the covering range of the closing plate 24 is the shielding area 22. The bracket 23 drives the closing plate 24 to cover or avoid the return air opening 11 by moving. The ceiling machine panel assembly of the present invention realizes the shielding of the return air opening 11 by setting the closing plate 24. That is to say, the covering range of the closing plate 24 is the shielding area 22 of the moving part 20. When the moving part 20 is in the closed position, the closing plate 24 covers the return air opening 11 to close the return air opening 11, improving the overall appearance integrity, and can prevent dust from falling and insects from entering the equipment interior, improving reliability. When the moving part 20 is in the open position, the closing plate 24 avoids the return air opening 11, thereby opening the return air opening 11 to realize return air.

[0038] As Figure 3 shown in the first embodiment, there are multiple return air openings 11, and the multiple return air openings 11 are arranged at intervals. There are multiple closing plates 24, and in the closed position, the closing plates 24 are arranged in one-to-one correspondence with the return air openings 11. The ceiling machine panel assembly of the present invention can increase the return air volume by setting multiple return air openings 11 and closing plates 24. At the same time, the return air openings 11 can still be closed, improving the overall appearance integrity, and can prevent dust from falling and insects from entering the equipment interior, improving reliability.

[0039] In the above embodiments, in order to make the return air panel of the ceiling unit more beautiful, the return air openings 11 may be arranged at intervals in the circumferential direction, and all the closing plates 24 are also arranged at intervals in the circumferential direction. A return air area 21 is formed between two adjacent closing plates 24.

[0040] In the above embodiments, the shape of the closing plate 24 matches the shape of the return air opening 11. In the closed position, the closing plate 24 covers the return air opening 11, and there is a smooth transition between the outer surface of the closing plate 24 and the outer surface of the return air panel 10. Due to the matching shape of the closing plate 24 and the return air opening 11 in the ceiling unit panel assembly of the present invention, when the moving part 20 is in the closed position, the closing plate 24 can completely close the return air opening 11, thereby making the appearance more beautiful and preventing insects from entering the interior of the device. In addition, due to the smooth transition between the outer surface of the closing plate 24 and the outer surface of the return air panel 10, the outer edge surface of the closing plate 24 and the outer surface of the return air panel 10 can be integrated in appearance, greatly improving the overall aesthetic feeling of the ceiling unit.

[0041] In the above embodiments, the moving part 20 can rotate around its own rotation center. The moving part 20 includes a rotating sleeve 25 located at the rotation center, and the closing plate 24 is connected to the rotating sleeve 25. The open position and the closed position of the moving part 20 are switched during the rotation process. In the ceiling unit panel assembly of the present invention, the rotating sleeve 25 rotates to drive the connected closing plate 24 to rotate. During the rotation process, the closing plate 24 and the return air area 21 are continuously switched on the return air opening 11, so as to close or open the return air opening 11.

[0042] As Figure 4 and Figure 6 shown, in the second embodiment, the closing plate 24 has a first position embedded in the return air opening 11 and a second position abutting against the return air panel 10. When the moving part 20 is in the closed position, the closing plate 24 is in the first position, and there is a smooth transition between the outer surface of the closing plate 24 and the outer surface of the return air panel 10. When the moving part 20 is in the open position, the closing plate 24 is in the second position. In the ceiling unit panel assembly of the present invention, by enabling the closing plate 24 to be embedded in the return air opening 11, during the rotation process of the moving part 20, when the moving part 20 rotates to the closed position, the closing plate 24 is embedded in the return air opening 11, and there is a smooth transition between the outer surface of the closing plate 24 and the outer surface of the return air panel 10, thereby preventing insects from entering the interior of the device. In addition, due to the smooth transition between the outer surface of the closing plate 24 and the outer surface of the return air panel 10, the outer edge surface of the closing plate 24 and the outer surface of the return air panel 10 can be integrated in appearance, greatly improving the overall aesthetic feeling of the ceiling unit. When the moving part 20 rotates to the open position, the closing plate 24 abuts against the return air panel 10, and at this time the return air area 21 covers the return air opening 11, thereby opening the return air opening 11.

[0043] As Figure 5 andFigure 7 As shown in the above-mentioned second embodiment, a first guiding surface 241 is formed at the edge of the closing plate 24, and a second guiding surface 12 matching the first guiding surface 241 is provided on the inner wall of the air return opening 11; the first guiding surface 241 and the second guiding surface 12 are used to guide the closing plate 24 to move from the first position to the second position during the process of the moving part 20 moving from the closed position to the open position. By providing the first guiding surface 241 and the second guiding surface 12, the ceiling machine panel assembly of the present invention, during the process of the moving part 20 moving from the closed position to the open position, through the cooperation of the first guiding surface 241 and the second guiding surface 12, guides the closing plate 24 from the first position to the second position, realizing a smooth switching between the open position and the closed position of the moving part 20.

[0044] In the above-mentioned embodiment, when the closing plate 24 is in the first position, the first guiding surface 241 and the second guiding surface 12 are mutually buckled, making the overall closing effect of the closing plate 24 better and preventing a gap from appearing between the edge of the closing plate 24 and the air return opening 11.

[0045] As Figure 2 shown in the first embodiment, the ceiling machine panel assembly further includes a driving device 30. The driving device 30 is arranged on the air return panel 10, and the driving device 30 is drivingly connected to the moving part 20. Under the drive of the driving device 30, the moving part 20 switches between the open position and the closed position. By providing the driving device 30 to drive the moving part 20 to move, the ceiling machine panel assembly of the present invention, under the drive of the driving device 30, enables the moving part 20 to switch between the open position and the closed position, which is convenient for control.

[0046] In Figure 8 the shown third embodiment, the moving part 20 is rotatable along its own rotation center. A rotating sleeve 25 is arranged at the rotation center of the moving part 20, and the driving shaft 321 of the driving device 30 is drivingly connected to the rotating sleeve 25. By arranging the rotating sleeve 25 on the moving part 20, the ceiling machine panel assembly of the present invention enables the driving device 30 to drive the rotating sleeve 25 to rotate. While the rotating sleeve 25 rotates, it drives the moving part 20 to rotate, so as to switch the moving part between the open position and the closed position.

[0047] In the above-mentioned embodiment, heat dissipation grooves 253 are provided on the rotating sleeve 25, and the driving device 30 can dissipate heat through the heat dissipation grooves 253.

[0048] In the above embodiments, a driving hole 251 is provided on the rotating sleeve 25, and the driving shaft 321 is inserted into the driving hole 251. Preferably, the free end of the driving shaft 321 can penetrate out of the driving hole 251 and be located outside the rotating sleeve 25; a limiting groove is provided on the inner circumference of the driving hole 251, and a limiting protrusion matching the limiting groove is provided on the driving shaft 321. When the driving shaft 321 is inserted into the driving hole 251, the limiting protrusion is located in the limiting groove. When the driving shaft 321 rotates, the driving shaft 321 drives the rotating sleeve 25 to rotate circumferentially through the cooperation of the limiting protrusion and the limiting groove. That is to say, in the circumferential direction of the driving shaft 321, the driving hole 251 is in driving cooperation and limiting cooperation with the driving shaft 321; while in the axial direction of the driving shaft 321, there is no limiting structure. Therefore, the rotating sleeve 25 is movable relative to the driving shaft 321; the rotating sleeve 25 has a third position and a fourth position; in the third position, the rotating sleeve 25 is close to the free end of the driving shaft 321; in the fourth position, the rotating sleeve 25 is far from the free end of the driving shaft 321.

[0049] When the moving part 20 of the ceiling machine assembly of the present invention is in the open position, the rotating sleeve 25 is in the third position, and at this time, the closing plate 24 is in the second position.

[0050] When the moving part 20 switches from the open position to the closed position, while the rotating sleeve 25 drives the closing plate 24 to rotate, a pressure is also applied to the closing plate 24, so that the closing plate 24 abuts against the return air panel 10. When the rotating sleeve 25 drives the closing plate 24 to rotate to a position corresponding to the return air opening 11, since the closing plate 24 loses support, the closing plate 24 and the rotating sleeve 25 both descend, and the closing plate 24 is embedded in the return air opening 11 to close the return air opening 11. The rotating sleeve 25 is displaced to a position far from the free end of the driving shaft 321. At this time, the moving part 20 is in the closed position, the position of the closing plate 24 is the first position, and the position of the rotating sleeve 25 is the fourth position.

[0051] When the moving part 20 continues to rotate, the moving part 20 can switch from the closed position to the open position. During this process, the rotating sleeve 25 continues to drive the closing plate 24 to rotate. Due to the existence of the first guiding surface 241 and the second guiding surface 12, during the rotation process, the rotating sleeve 25 and the closing plate 24 continuously rise. When the return air area 21 completely corresponds and coincides with the return air opening 11, at this time, the closing plate 24 completely rises above the return air panel 10 and abuts against the return air panel 10 again. At this time, the closing plate 24 is in the second position, the rotating sleeve 25 is in the third position, and the moving part 20 is in the open position.

[0052] The ceiling machine panel assembly of the present invention realizes the driving and limiting cooperation between the driving hole 251 and the driving shaft 321 in the circumferential direction of the driving shaft 321; while in the axial direction of the driving shaft 321, the rotating sleeve 25 is movable relative to the driving shaft 321. With a simple structure, it can achieve circumferential transmission and axial movement at the same time, so as to realize the effect of embedding the closing plate 24 into the air return opening 11.

[0053] In the above embodiment, an elastic member 40 is provided between the rotating sleeve 25 and the driving device 30. One end of the elastic member 40 is fixed on the driving device 30, and the other end abuts against the rotating sleeve 25. The elastic force direction of the elastic member 40 is parallel to the axis direction of the driving shaft 321.

[0054] The elastic member 40 of the ceiling machine panel assembly of the present invention is preferably a spring. One end of the spring is fixed on the driving device 30, and the other end abuts against the rotating sleeve 25. The elastic force direction of the spring is parallel to the axis direction of the driving shaft 321, and the elastic force direction of the spring is always applied to the rotating sleeve 25, and the elastic force of the spring always faces the air return panel 10, so that the rotating sleeve 25 can apply pressure to the closing plate 24. When the moving part 20 is in the open position, the closing plate 24 rises to the second position under the supporting force of the air return panel 10, and the rotating sleeve 25 also moves to the third position accordingly. At this time, the spring is compressed. When the moving part 20 moves to the closed position, due to the small supporting force of the air return panel 10, the spring resets and pushes the rotating sleeve 25 to the fourth position. The rotating sleeve 25 drives the closing plate 24 to descend to the first position, so as to be embedded into the air return opening 11.

[0055] The ceiling machine panel assembly of the present invention realizes the axial movement and reset by cooperating with a spring, a driving device 30 and a rotating sleeve 25, so as to realize complex functions with a simple structure, greatly simplify the structure of the ceiling machine panel assembly, and save the process and material costs.

[0056] In the above embodiments, the driving device 30 includes a mounting base 31 and a first driving motor 32. The mounting base 31 is disposed on the return air panel 10. A first motor cavity 313 is provided in the mounting base 31, and the rotating sleeve 25 is sleeved on the mounting base 31. The first driving motor 32 is installed in the first motor cavity 313, and the output shaft of the first driving motor 32 is a driving shaft 321. A first protrusion 311 is provided on the outer periphery of the mounting base 31, and a second protrusion 252 corresponding to the first protrusion 311 is provided on the inner wall of the rotating sleeve 25. An installation space for installing the elastic member 40 is formed between the first protrusion 311 and the second protrusion 252. In the circumferential direction of the rotating sleeve 25, the second protrusion 252 is rotatable relative to the rotating sleeve 25. In the axial direction of the rotating sleeve 25, the second protrusion 252 is in limit fit with the rotating sleeve 25. The ceiling machine panel assembly of the present invention is provided with a mounting base 31. By providing a first protrusion 311 on the mounting base 31 and a second protrusion 252 on the rotating sleeve 25, an installation space for installing the elastic member 40 is formed therebetween. The elastic member 40 generally uses a spring. There are three advantages of adopting this installation structure. First, the spring is built-in, making the entire driving structure more integrated and occupying less space. Second, the above structure ingeniously changes the elastic direction of the spring. When the spring is compressed, the elastic direction is to push the rotating sleeve 25 towards the return air panel 10, rather than pushing the rotating sleeve 25 away from the return air panel 10. Third, by providing the second protrusion 252, it can prevent the spring from directly contacting the rotating sleeve 25. Since the rotating sleeve 25 rotates, if the spring directly contacts the rotating sleeve 25, it is easy to be misaligned. By providing the second protrusion 252, the running stability can be improved.

[0057] As Figure 2 shown in Embodiment 1, the driving device 30 includes a mounting base 31 and a first driving motor 32. The mounting base 31 is disposed on the return air panel 10. A first motor cavity 313 is provided in the mounting base 31, and the rotating sleeve 25 is sleeved on the mounting base 31. The first driving motor 32 is installed in the first motor cavity 313, and the output shaft of the first driving motor 32 is a driving shaft 321. A partition 312 is provided in the mounting base 31. The partition 312 divides the mounting base 31 into a first motor cavity 313 and a second motor cavity 314. A second driving motor 33 is installed in the second motor cavity 314, and the second driving motor 33 is drivingly connected to the detection device 50 of the ceiling machine. The ceiling machine panel assembly of the present invention divides the interior of the mounting base 31 into two motor cavities by providing a partition 312 in the mounting base 31, so that not only the motor for driving the moving part 20 can be installed, but also the motor for driving the detection device 50 of the ceiling machine can be installed, realizing multiple functions with one object.

[0058] In the above embodiments, the mounting base 31 is located at the center of the return air panel 10, the detection device 50 is installed at the center of the return air panel 10, and the return air openings 11 are located around the center of the return air panel 10. By arranging the mounting base 31 at the center of the return air panel 10, the ceiling machine panel assembly of the present invention can achieve a high degree of functional integration. It can not only install the driving structure of the moving part 20 in the mounting base 31, but also install the structure for driving the detection device 50. Moreover, the overall structure is very simple and occupies little space.

[0059] In Figure 9 In the fourth embodiment shown, the ceiling machine panel assembly further includes a detection device 50 and a display device 60. The detection device 50 is movably arranged on the outer surface of the return air panel 10 and is used for real-time monitoring of the body temperature and / or position of indoor personnel. The ceiling machine panel assembly of the present invention is provided with a display screen for displaying the ambient temperature, function display, etc. The ceiling machine is also provided with a detection device 50, a wind deflector, an air outlet, and a return air opening. The detection device 50 has an infrared human body temperature detection function. After this function is turned on, the detection device 50 can rotate within a 360-degree range to perform real-time monitoring of the body temperature and position of indoor personnel. By analyzing the body temperature data, the opening and closing angles of individual wind deflectors can be adjusted to control the air volume and angle of each air outlet; for example, when the air conditioner is turned on in the cooling mode and it detects that there is someone in the room and the body temperature is high, it can be judged that the user may need to cool down quickly at this time. Therefore, the wind deflector in the direction where the user is located is adjusted so that its opening angle is the largest while the opening angles of other wind deflectors are smaller. At this time, the air volume in the direction where the user is located will be the largest, and the surrounding temperature will be preferentially reduced, allowing the user to quickly reach a comfortable state and improving comfort. At the same time, the detection device 50 also has a video recording function, which can be turned on when the air conditioner is turned on or off and can replace a camera to monitor the indoor situation without dead angles within a 360-degree range. The return air openings 11 are evenly distributed around the detection device 50 on the panel.

[0060] In the above embodiments, the ceiling machine panel assembly further includes a filter screen. The filter screen is on the moving part 20 and covers the return air area 21, so that while the return air openings 11 return air, the return air can be filtered.

[0061] According to another embodiment of the present invention, a ceiling machine is also disclosed, including the above-mentioned ceiling machine panel assembly.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not limitations on the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the embodiments here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
