The panel 1 is provided with an air inlet 11. The face frame 2 is annular, and the face frame 2 cover is established outside panel 1, and the face frame 2 is gone up to encircle panel 1 and is equipped with air outlet 23. The air deflector 3 is movably arranged at the air outlet 23, a plurality of non-wind-sensing through holes 32 are formed in the air deflector 3, an included angle is formed between the air deflector 3 and the panel 1 when the air outlet 23 is covered, so that the non-wind-sensing through holes 32 are used for discharging air in the direction deviating from the axis of the air inlet 11, and the included angle between the air discharging direction of the non-wind-sensing through holes 32 and the axis of the air inlet 11 is 20-30 degrees.

It can be understood that the face frame 2 can fix and limit the panel 1, and the installation stability of the panel 1 is improved. The face frame 2 may further define an air outlet 23, thereby improving the air blowing effect of the panel assembly 100.

As shown in fig. 3, the air guiding plate 3 is movably disposed at the air outlet 23. If the air deflector 3 can move to cover the air outlet 23, an included angle is formed between the air deflector 3 and the panel 1, so that the non-wind-sensing perforation 32 blows air in a direction deviating from the axis of the air inlet 11, the air supply quantity of the panel assembly 100 can be increased, and the air supply flow is reduced to flow towards the air inlet 11. It should be noted that, in the panel assembly in the prior art, when the air deflector covers the air outlet, the air deflector and the panel are on the same horizontal line, and when the decorating machine is in a heating mode, the air deflector rotates to vertically guide the air downwards, that is, the air deflector makes the air outlet form an air outlet direction parallel to the axis; when the ceiling machine is in a refrigeration mode, the air deflector rotates, inclines and guides air downwards, namely the air deflector enables the air outlet to form a certain included angle (such as 45-75 degrees) with the axis; when the ceiling machine is in a no-wind-sense mode, the air outlet is closed by the air deflector, and only the micropores on the air deflector are used for air outlet. In the scheme, the ceiling fan has strong wind sense in the first two modes, the head of a user is easily blown directly, the use comfort is reduced, the air supply airflow at the air outlet is easily sucked away from the air inlet in the wind-sensing-free mode, the air outlet quantity is too small, the air supply effect is general, and the ceiling fan is not suitable for use when the indoor temperature and the set temperature of the air conditioner are greatly different.
