1. Organizational composition:

The air guide system of the upper and lower air outlet wall-mounted machine is mainly composed of: the moving panel 3, the lower air guide plate (the first air guide plate 21), the sealing foam (the sealing part 6), the panel body 4 and the connecting rod 8. Among them, the material of the sealing foam should have the functions of heat preservation and heat insulation.

Here, a driving form of the sealing foam is given: the bottom of the sealing foam is fixed with the connecting rod 8, and the other end of the connecting rod is at the rotation center 9 of the sealing foam, as shown in Figure 4; 7 Direct-drive connecting rods drive the sealing foam to rotate.

The air outlet ducts of the upper and lower air outlet wall-mounted machines are composed of two: a lower air outlet duct (not shown, that is, the position of the first air outlet 41 ) and an upper air duct 7 .

2. The working principle of the organization:

When the air conditioner is in the lower air outlet condition, as shown in Figure 2. The lower air deflector is pushed out and moved until the lower air outlet is exposed (that is, the first air outlet 41 is opened); at this time, the sealing foam does not move, and is hidden in the space formed by the moving panel 3 and the panel body 4, Does not affect appearance.

When the air conditioner is in the upper air outlet condition, as shown in Figure 3. Both the lower air deflector and the motion panel move and form an overlap; at this time, the lower air deflector, the motion panel and the panel body form the upper air duct 5; at this time, there is a gap between the tail of the lower air deflector and the panel body 4 Larger gaps do not form lap seals, and the tail of the lower air deflector is prone to condensation. Therefore, when the sealing foam is in the upper air outlet condition, it needs to rotate around the rotation center 9 to the top of the lower air deflector to seal the tail of the lower air deflector and prevent condensation there.

When the air conditioner is converted from the upper air outlet working condition to the lower air outlet working condition, the sealing foam rotates around the rotation center 9 to the initial position; the movement panel is retracted. The material of the sealing foam is arbitrary, as long as it has the properties of heat preservation, heat insulation and sealing. The driving form of the sealing foam is not limited, as long as it can move to the desired position for sealing and hiding.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection of the utility model. The above are only the preferred embodiments of the present utility model. It should be pointed out that for those skilled in the art, without departing from the technical principles of the present utility model, several improvements and modifications can be made. These improvements and modifications should also be regarded as the protection scope of the present invention.
