The first fan 6 includes a first driving motor 61 and a first fan blade 62. The first fan blade 62 is preferably a mixed flow fan blade. The mixed flow fan blade is mainly formed by combining the advantages of traditional centrifugal and cross flow fan blades, and has high pressure and large Air volume characteristics. The first blade 62 may also be an axial flow blade or a centrifugal blade.

The first air outlet part 1 is a wedge-shaped shape whose longitudinal thickness gradually becomes thinner from the front end to the rear end, and the rear end of the first air outlet part is pivotally connected to the rear end of the housing part, An air outlet component 1 is provided with a first air outlet 11 and a first air deflector 12 .

The driving mechanism is used to rotate the first air outlet part 1. When cooling or heating, the driving mechanism drives the first air outlet part 1 to rotate outward around the axis, and the first air outlet 11 is exposed (as shown in FIG. 1 ). Thus cold wind or hot wind is blown out from the first air outlet 11; when shutting down, the driving mechanism drives the first air outlet part 1 to rotate inwardly around the axis, and the first air outlet 11 is hidden (as shown in Figure 2) in the housing part 2, To achieve the overall appearance, more beautiful. The drive mechanism includes a motor (not shown in the figure) and a meshing master gear (not shown in the figure) and a slave gear (not shown in the figure), the slave gear is installed on the shaft, and the master gear is connected to the output shaft of the motor .

Below in conjunction with Fig. 4, 5 further elaborates the working principle of the air conditioner of the present embodiment:

When starting the cooling, as shown in Figure 4, open the driving mechanism, the first air outlet part 1 is rotated outwards, the first air outlet 11 is exposed, and the second fan of the second air outlet part 7 does not work. When the first fan blade 62 is running, a high-pressure wind field is generated, and the second fan blade 75 stops, and the external air of the air conditioner is absorbed into the heat exchange area through the first air inlet on the housing part 2, that is, the heat exchanger 5 generates a high-pressure wind field. heat exchange. The cold air flow after heat exchange is sucked onto the first air outlet part 1, and then blown out through the first air outlet 11, and the cold air can be blown to any direction of the room through the air deflector. Due to the high density of the cold air, it sinks gradually, quickly reducing the temperature of the entire space.

When turning on the machine for heating, as shown in Figure 5, the drive mechanism is opened, the first air outlet part is rotated outwards, the first air outlet is exposed, and the second fan of the second air outlet part is turned on. The operation of the second fan blade 75 generates a high-pressure wind field, and the first fan blade 62 also operates to generate a high-pressure wind field. The external air of the air conditioner is absorbed into the heat exchange area through the first air inlet on the housing part 2, that is, the heat exchanger 5 to generate heat exchange. The hot air after heat exchange is sucked into the first air outlet 11 and the second air outlet 31 of the air conditioner to realize hot air from up and down, and rapidly raise the temperature of the entire space. Of course, when the machine is turned on for heating, the first fan of the first air outlet part may not be turned on, and only the second fan of the second air outlet part is turned on.

It can be seen that, through the vertical air conditioner provided by the present invention, rapid heating and rapid cooling are realized, and the comfort of the air conditioner is improved; moreover, the first air outlet part 1 is hidden in the housing part 2 when not in use, To achieve the overall appearance, more beautiful.
