[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the figures and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0031] As Figs. 1 to 4The illustrated ceiling machine comprises a main frame 1, an air outlet assembly 2 arranged on the main frame 1, and a first air outlet 10 formed between the air outlet assembly 2 and the main frame 1. The air outlet assembly 2 is provided with a second air outlet 21. The air deflector 3 comprises a first air deflector part 31 and a second air deflector part 32 connected to each other. The connection part of the first air deflector part 31 and the second air deflector part 32 is rotatably arranged on the air outlet assembly 2. The air deflector has a first state in which the first air deflector part 31 closes the first air outlet 10, and the second air deflector part 32 closes the second air outlet 21. At this time, the edge of the first air deflector part 31 abuts and seals against the main frame 1, and the second air deflector part 32 seals against the edge of the second air outlet 21. The first air outlet 10 and the second air outlet 21 are simultaneously closed by the air deflector 3. In the premise of reliably guiding the air outlet of the ceiling machine, when the ceiling machine is in a shutdown state, dust or impurities outside the ceiling machine cannot enter the interior of the ceiling machine. The first air deflector part 31 can also close the opening formed at the first air outlet 10, and the second air deflector part 32 can close the opening formed at the second air outlet 21, so that the external shape of the ceiling machine in the shutdown state is complete, thereby ensuring the aesthetic appearance of the ceiling machine.

[0032] Preferably, the air deflector further has a second state in which the first air outlet 10 and the second air outlet 21 are simultaneously opened. When the air deflector 3 is in the second state, the first air deflector part 31 opens the first air outlet 10, and the second air deflector part 32 opens the second air outlet 21. At this time, the first air deflector part 31 is in the plane of the air outlet assembly 2, and the second air deflector part 32 extends into the interior of the main frame 1, so that the airflow in the main frame 1 is divided into two parts. One part flows horizontally through the first side of the second air deflector part 32, the first air deflector part 31, and then is discharged from the first air outlet 10. The other part flows vertically downward through the second side of the second air deflector part 32 and the second air outlet 21.

[0033] As an embodiment, the air outlet assembly 2 is provided with a receiving part. In the second state, the first air deflector part 31 is rotated into the receiving part. The receiving part is used to prevent interference between the first air deflector part 31 and the air outlet assembly 2 when the air deflector 3 is rotated. When the first air deflector part 31 is in the receiving part, the first air deflector part 31 can completely leave the range of the first air outlet 10, thereby completely opening the first air outlet 10 and ensuring the air volume of the first air outlet 10.

[0034] As another implementation, the air deflector further has a third state of closing the first air outlet 10 and opening the second air outlet 21; when the air deflector 3 is in the third state, the first air deflector part 31 opens the first air outlet 10, the second air deflector part 32 opens the second air outlet 21 and closes the first air outlet 10, at this time the first air deflector part 31 is located below the air outlet assembly 2, and the edge of the second air deflector part 32 abuts and seals against the main body frame 1, all the gas in the main body frame 1 can only flow through the second side surface of the second air deflector part 32 and then be discharged by the second air outlet 21, so as to achieve the purpose of rapid heating.

[0035] Further, the air outlet assembly 2 is provided with a bypass opening, and when the air deflector switches between the first state and the third state, the first air deflector part 31 passes through the bypass opening. The bypass opening facilitates the rotation of the first air deflector part 31, so as to ensure that the first air deflector part 31 can close the first air outlet 10 or can be moved to below the air outlet assembly 2 to enable the second air deflector part 32 to close the first air outlet 10.

[0036] As another implementation, the difference from the foregoing embodiments is that the bypass opening on the air outlet assembly 2 forms a receiving part, that is, the air deflector 3 simultaneously has the second state and the third state, and the air deflector 3 can rotate the first air deflector part 31 and keep it at the bypass opening, or can rotate the first air deflector part 31 to below the air outlet assembly 2 through the bypass opening.

[0037] Preferably, in the second state, the plane where the first air deflector part 31 is located is parallel to the lower surface of the air outlet assembly 2. That is, the included angle b between the plane where the first air deflector part 31 is located and the lower surface of the air outlet assembly 2 is 0°.

[0038] The included angle a between the first air deflector part 31 and the second air deflector part 32 ranges from 100° to 150°. If the included angle a is too small, the air volume of the first air outlet 10 will be greatly reduced in the second state, and if the included angle a is too large, the air volume of the second air outlet 21 will be greatly reduced in the second state; in both cases, comfort is not conducive. Only when the included angle a is in a reasonable range (100° to 150°) can the air volume of the first air outlet 10 and the second air outlet 21 be ensured, and ultimately the air outlet effect of the ceiling machine can be ensured. The included angle a is determined according to the positional relationship between the first air outlet 10 and the second air outlet 21.

[0039] In the third state, the angle b between the plane of the first air guide portion 31 and the lower surface of the air outlet assembly 2 is in the range of -60° to -10° (the angle formed when the first air guide portion 31 is below the air outlet assembly 2 is taken as a negative angle). The value of the angle b can be determined on the basis of the determined value of the angle a, and the value of the angle b when the second air guide portion 32 closes the first air outlet 10.

[0040] In the first state, the angle b between the first air guide portion 31 and the lower surface of the air outlet assembly 2 is in the range of 30° to 80° (the angle formed when the first air guide portion 31 is above the air outlet assembly 2 is taken as a positive angle). The value of the angle b can be determined on the basis of the determined value of the angle a, and the value of the angle b when the second air guide portion 32 closes the second air outlet 21, so as to ensure that the first air guide portion 31 closes the first air outlet 10 while the second air guide portion 32 closes the second air outlet 21.

[0041] It should be noted that the main frame 1 is the main load-bearing structure of the ceiling-mounted air conditioner, and is used to be mounted on the ceiling when the ceiling-mounted air conditioner is installed. Other structures can be directly or indirectly mounted on the main frame 1 and fixed to the ceiling through the main frame 1. The ceiling-mounted air conditioner has an indoor unit mounted in the ceiling, the main frame 1 is connected to the indoor unit, and the air outlet assembly 2 is connected to the main frame 1. The indoor unit has an indoor unit air outlet, the first end of the air outlet duct of the main frame 1 is in communication with the indoor unit air outlet, and the air flow path is: return air outlet-evaporator-indoor unit air outlet-first end of air outlet duct-second end of air outlet duct-first air outlet 10 and / or second air outlet 21.

[0042] The main frame 1 and the air outlet assembly 2 form an air supply duct 11, the first end of the air supply duct 11 forms the first air outlet 10, and the first air guide portion 31 can rotate into the air supply duct 11 and abut against the main frame 1 to seal. When the first air guide portion 31 abuts against the main frame 1, the first air guide portion 31 can cut off the air supply duct 11 so that there is no gas flow at the first air outlet 10. When the air guide plate 3 switches between the first state and the second state, the first air guide portion 31 moves between entering the air supply duct 11 and leaving the air supply duct 11.

[0043] Optionally, an air outlet duct 12 is formed in the main frame 1, one end of the air outlet duct 12 is communicated with the second end of the air supply duct 11, and the second air guide part 32 can rotate into the air outlet duct 12 and abut and seal with the main frame 1. When the second air guide part 32 abuts with the main frame 1, the second air guide part 32 can cut off the air flow between the air supply duct 11 and the air outlet duct 12 to make no air flow at the first air outlet 10, thereby achieving the effect of closing the first air outlet 10. At the same time, the second air guide part 32 can also guide the air flow in the air supply duct 11 to the second air outlet 21, thereby achieving the vertical downward air outlet of the ceiling machine.

[0044] The ceiling machine further comprises a driving mechanism 4, which is arranged on the air outlet assembly 2 and can drive the air guide plate 3 to rotate.

[0045] Specifically, the driving mechanism 4 comprises a driving motor, a rotating shaft is arranged on the air guide plate 3, a rotating gear is arranged on the rotating shaft, and the output gear of the driving motor is engaged with the rotating gear to realize the rotation of the air guide plate 3.

[0046] The air outlet assembly 2 comprises an air outlet frame, the first air outlet 10 is formed between the air outlet frame and the main frame 1, and the air guide plate 3 is rotatably arranged on the air outlet frame. In other embodiments not shown, the air outlet assembly 2 comprises an air outlet frame and an air return panel, the first air outlet 10 is formed between the air outlet frame and the main frame 1, and the air return panel is provided with an air return port.

[0047] A control method of the ceiling machine, the air guide plate further has a second state of simultaneously opening the first air outlet 10 and the second air outlet 21, in the second state, the first air guide part 31 opens the first air outlet 10, the second air guide part 32 opens the second air outlet 21, and the control method comprises:

[0048] It is judged whether quick heat exchange is needed, wherein the quick heat exchange includes quick cooling and quick heating. Generally, if the customer selects quick heat exchange, it means that the user's heat exchange (cooling or heating) demand is relatively high, and if the quick heat exchange is not selected, it means that the user's heat exchange demand is relatively low. Therefore, in order to better meet the user's demand, it is necessary to judge whether the ceiling machine needs quick heat exchange before controlling the air outlet of the ceiling machine;

[0049] When the judgment result is yes, it means that the user's heat exchange demand is relatively high at this time, so the air guide plate 3 is controlled to switch to the second state. The first air outlet 10 and the second air outlet 21 both perform air outlet to increase the air outlet volume of the ceiling machine as much as possible, thereby achieving the purpose of quick heat exchange.

[0050] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
