Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model relates to a HVAC air door structure, as shown in FIG. 1, including the HVAC box, HVAC box is inside to be set up and to blow face wind channel 1, blow 1 intercommunication left defrosting wind channel 4 and right defrosting wind channel 5 in the face wind channel, blow 1 well fixed connection air door connecting rod 2 in the face wind channel, cup joint mode air door 6 on the air door connecting rod 2, blow and set up mode executor 3 on 1 lateral wall in face wind channel, mode executor 3 connects mode air door 6, the output of 3 electricity connection air conditioner controllers of mode executor, mode executor 3 drives and carries out mode air door 6 closure, thereby reach the control to each mode of air conditioner, still be provided with the air-blower that links to each other in proper order through the wind path in the HVAC box, hot-water tank.

The face blowing air duct 1 is communicated with a left defrosting air duct 4 and a right defrosting air duct 5.

The mode air door 6 comprises a square shaft, an air door connecting rod 2 is sleeved on the square shaft, at least two air door plates are fixed on the square shaft, a square shaft seat is installed at the end part of the square shaft, and a rubber sealing strip is integrally arranged on the square shaft seat close to the edge of the air door plate; as shown in fig. 2 and 3, in this embodiment, a structure that two mode air doors 6 are connected and assembled is adopted, a sealing step is arranged on a square shaft opposite to the two mode air doors 6, the sealing step and the face blowing air duct 1 are assembled to form a sealing structure, three air door plates are assembled on the square shafts of the two mode air doors 6, the square shafts of the two mode air doors 6 rotate coaxially, an effective air outlet area is increased, and air outlet volume distribution of the HVAC assembly is optimized.

As shown in figure 4, the length of the air door plate is adapted to the inner wall of the face blowing air duct 1, the end part of the air door plate adopts a soft sealing strip, and the air door plate can effectively seal air.

In the embodiment, the two mode air doors 6 are arranged on the air door connecting rod 2, the two mode air doors 6 coaxially rotate under the control of the mode actuator 3, and the mode air doors 6 penetrate through and are fixed in the face blowing air duct 1 through the air door connecting rod 2, so that the air flow direction is smoother, and the wind resistance is reduced; the mode executor 3 adopts a micromotor to drive different mode air doors 6 of the air conditioner to operate, and air can be guided into the left defrosting air channel 4 and the right defrosting air channel 5 along the mode air doors 6.

The utility model relates to a working process of HVAC air door structure is: the mode actuator 3 drives the air door connecting rod 2 and the mode air door 6, and the opening and the closing of the mode air door 6 in the face blowing air duct 1 are realized to realize the air outlet of the face blowing air duct 1 and the defrosting air duct opening.
