Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to more clearly illustrate the technical characteristics and the beneficial effects of the air guide mechanism, the embodiment of the present invention provides an air guide mechanism and an air conditioner indoor unit.

Referring to fig. 1 and 2, in a first embodiment, the indoor unit of the air conditioner includes a wind guiding mechanism, and a heat exchanger and a fan installed in the wind guiding mechanism. The air guide mechanism comprises a shell 10, wherein an air inlet, an air outlet 101 and an air duct 102 communicating the air inlet and the air outlet 101 are formed in the shell 10. The heat exchanger and the fan are arranged in the air duct 102, and the fan is arranged at the air inlet. The fan is used for generating negative pressure, external air 90 is sucked into the air channel 102 from the air inlet, and the air 90 is subjected to temperature change through the heat exchanger and then blown out from the air outlet 101.

In practical application, the air conditioner indoor unit can be constructed into a vertical air conditioner indoor unit which can stably stand on the ground, and the air conditioner indoor unit can also be constructed into a wall-mounted air conditioner indoor unit which is hung on the wall surface so as to adapt to various space arrangement requirements. This embodiment adopts the floor air conditioner indoor unit, casing 10 is including connecting in the side between its top and bottom, the air intake is located on the side of casing 10 and near the bottom setting of side, air outlet 101 is located on the side of casing 10 and near the top setting of side, the wind channel along the bottom of casing 10 extends in order to communicate to the direction on top air intake and air outlet 101. In this embodiment, the housing 10 includes a back plate 104 and a front plate 103 covering the back plate 104, the air outlet 101 is disposed on the front plate 103, and the air inlet is disposed on the back plate 104 to reduce noise, but in other embodiments, the air inlet 101 may also be disposed on the front plate 103 or other surfaces; the air outlet can also be arranged on other surfaces.

In the air conditioner indoor unit provided by this embodiment, when the air duct extends along the bottom of the housing 10 to the top to communicate the air inlet and the air outlet 101, air will impact the top end of the housing 10 along the air duct, and a high pressure area is formed at the top end of the housing 10, and then the air is blown out through the air outlet 101. Because the high-pressure area is formed close to the top end of the shell 10, the wind speed generated close to the top of the air outlet 101 is high, and the wind speed generated close to the bottom of the air outlet 101 is low; especially, when the existing air outlet is square, the phenomenon that the air quantity is concentrated on the top of the air outlet to blow out is obvious. In this embodiment, preferably, the periphery of the air outlet 101 is in a multi-arc enclosing shape, and the multi-arc enclosing shape may be a circle, an ellipse, a quasi-semicircle formed by smoothly connecting an arc and a large arc (I type in fig. 19), a quasi-ellipse formed by smoothly connecting two minor arcs and two large arcs (II type in fig. 19), or a quasi-triangle formed by smoothly connecting three minor arcs and three large arcs (III type in fig. 19), and the like. Compared with the traditional square air outlet, the air outlet 101 with the periphery in the multi-arc line enclosing shape has the advantage that the opening area of the upper part of the air outlet 101 is reduced, so that the air output of the upper part of the air outlet 101 can be reduced, and the effect of reducing the air output imbalance is achieved. And because the air will concentrate more in the centre of a circle of air outlet 101 and blow out, then adopt circular air outlet 101 can also make the air blow more farther.

The outer wind deflector 206 further comprises a plurality of outer wind deflectors 2061 connected to the inner arc surface of the arc-shaped profile plate 2064. The outer wind guide 206 further includes a rotation shaft 2063 formed on the outer arc surface thereof. The outer-layer air guide 206 is installed at the ventilation cavity and is rotatably inserted into the air outlet frame 40 through the rotating shaft 2063.

The effect of suction on the induced draft surface of the induced draft plate 4035A will occur as the air 90 flows over the induced draft surface of the induced draft plate 4035A and a greater attractive force will occur as the air 90 will leave the induced draft plate 4035A. In this embodiment, since the left and right ends of the air-inducing surface of the air-inducing plate 4035A will firstly generate the resistance to be separated from the air 90, and at this time, the resistance to be separated is not generated in the air 90 at the middle position, this will also make the air move closer to the middle position of the air-inducing plate 4035A.
