Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

This specific embodiment provides an air guide mechanism and an air conditioner indoor unit. In order to more clearly illustrate the technical characteristics and beneficial effects of the air guide mechanism, this embodiment uses the air guide The air conditioner indoor unit of the organization will be described.

Please refer to Fig. 1 and Fig. 2, in the first embodiment, the indoor unit of the air conditioner includes an air guide mechanism, a heat exchanger and a fan installed in the air guide mechanism. Wherein, the air guiding mechanism includes a casing 10 , and the casing 10 is formed with an air inlet, an air outlet 101 and an air duct 102 connecting the air inlet and the air outlet 101 .

Preferably, the two long sides of the partition 4034A extend in a C-shape with openings facing away from each other (Figure 11); On the one hand, since the two long sides of the partition 4034A extend in a C-shape with the openings facing away from each other, the windward area of the partition 4034A at its middle position is small, and the windward area at both ends of its length direction is large, and its middle The wind resistance of the position is small, so that the air 90 will move towards the middle position with less wind resistance during the flow process, so that the air 90 is more concentrated and blown out at the middle position of the partition plate 4034A, so that the outlet air is more concentrated. On the other hand, the windward surface of the baffle 4034A is in the shape of an arc arched towards the wind outlet side, then when the air 90 flows to the baffle 4034A, it will be subjected to the resistance of the middle position of the baffle 4034A before being resisted by the baffle 4034A. If the resistance at the two ends of the plate 4034A is reduced, the air 90 will have the effect of concentrating toward the middle of the partition 4034A during the flow process, so that the air 90 will flow out more concentrated on the axis 1011 of the air outlet 101 .

Preferably, the angle between the air-introducing surface of the air-introducing plate 4035A and the axis of the air outlet increases gradually in a direction away from the axis of the air outlet. Relative to the angle between the air-introducing surface of the air-introducing plate 4035A and the axis of the air outlet is constant, the wind resistance at the middle position of the air-introducing plate 4035A in this embodiment is smaller, while the air-introducing plate 4035A If the wind resistance at both ends of the air guide plate 4035A is greater, the air 90 will have the effect of moving towards the middle of the air guide plate 4035A during the flow process.

The air-introducing surface of the air-introducing plate 4035A includes an air-outlet edge facing the air-outlet side, and the air-outlet side is arc-shaped toward the air-outlet side. When the air 90 flows on the air-inducing surface of the air-introducing plate 4035A, it will be adsorbed on the air-inducing surface of the air-inducing plate 4035A, and when the air 90 is about to leave the air-inducing plate 4035A, a greater suction force will be generated. Then in the present embodiment, because the left and right ends of the air-introduction surface of the air-introduction plate 4035A will firstly produce the resistance that is about to break away from the air 90, and at this moment, the air 90 in the middle position does not produce the resistance that is about to break away. This will cause the air to move toward the middle position of the air guide plate 4035A.

Please refer to Fig. 17 and Fig. 18, Fig. 17 and Fig. 18 show the fifth embodiment of the indoor unit of the air conditioner of the present invention. This embodiment is based on the above-mentioned first embodiment, and the outer layer air guide part of the air guide device is replaced. In this specific embodiment, only the replaced structure will be described in detail, and other structures can refer to the above-mentioned embodiments.

In this embodiment, the air guide device includes an outer layer air guide 206D connected to the air outlet frame, and the outer layer air guide 206D includes an arc-shaped profile plate 2064D that matches the periphery of the ventilation cavity. The air guiding element 206D also includes several outer layer air guiding plates 2061D connected with the inner arc surface of the arc profile plate 2064D. Compared with the first embodiment, where the outer air deflector 2061 is planar, the air guide surface of the outer air deflector 2061D in this embodiment is arc-shaped. Therefore, it is more compatible with the periphery of the ventilation cavity, and in the swing motion, it can swing in a larger range without interference.

Preferably, the outer wind deflector 2061D includes a windward end surface (not marked), and the windward end surface of the transverse wind deflector is in the shape of an arc arched towards the wind outlet side. Preferably, the wind guide surface of the outer air guide plate 2061D includes an air outlet edge (not marked) facing the air outlet side, and the wind outlet edge of the transverse air guide plate is arc-shaped toward the air outlet side. Similar to the principle of the partition, both of the above two features can make the air 90 flow toward the air outlet 101 to produce a central concentration effect.
