As shown in the air conditioner 100 of FIGS. 1 and 2, the air conditioner 100 includes a housing 30, a first air guide plate 10 and a second air guide plate 20. The housing 30 is provided with a ventilation duct (not shown in the drawing) formed inside the housing 30 and a ventilation port (not shown in the drawing) communicating with the ventilation duct and installed on an edge of the housing 30. No.), the first baffle plate 10 is rotatably installed in the blower port, and is connected to the housing 30 via the first rotation shaft 12 on the housing 30. The second baffle plate 20 is rotatably installed in the air duct, the second baffle plate 20 is rotated via the second rotating shaft 22 on the housing 30, and the air conditioner 100 is in the direct wind prevention mode. When the air conditioner 100 operates in the direct air flow prevention mode, the first air guide plate 10 blocks a part of the blower port.

Specifically, the components of the air conditioner 100 are mounted in the casing 30, and the casing 30 supports and protects the internal components, and is also used for beautifying the appearance. The housing 30 includes a base 31, a frame (not shown in the drawing) and a panel 32. The frame is installed on the base 31, the front side of the frame is open, and the panel 32 is installed on the front side of the frame. A ventilation port is defined between the lower end of the frame and the frame.

Specifically, the frame may be rotatably or detachably installed on the base 31, and the panel 32 may be rotatably or detachably installed on the frame. It can be understood that the air conditioner 100 further includes a flap 50, the flap 50 is rotatably installed in the air duct, and the lateral swing is controlled by controlling the lateral swing. Let's see The air conditioner 100 further includes a fan 40 provided inside the housing 30.

In the embodiment of the present application, a ventilation duct for air circulation is further provided in the housing 30, and the ventilation duct forms a ventilation port on an edge of the housing 30 to start the air conditioner 100. At that time, the temperature of the room is adjusted by blowing the air into the indoor space through the air outlet. The first air guide plate 10 rotates about the first rotation shaft 12 to open or close the blower port. In the present embodiment, the second air guide plate 20 is provided with second air diffuser holes 21 penetrating the plurality of second air guide plates 20, and the second air diffuser holes 21 are the second air guide plates. The second baffle plate 20 is installed along the thickness direction of 20, and is rotatable in the air duct along the second rotating shaft 22. When the air conditioner 100 operates in the direct wind prevention mode, the first air guide plate 10 rotates by an angle for blocking a part of the blower port. The air blown out from the air conditioner is blocked by the first air guide plate 10 to reduce the air volume and the air velocity at the air outlet. As a result, the wind blown out by the air conditioner 100 is prevented from being blown directly on the human body, and the wind felt by the person is made softer. Furthermore, it avoids the unity of ventilation of the air conditioner and responds to the needs of users in various modes.

Furthermore, when the first baffle plate 10 closes the blower port, the side edge of the first baffle plate 10 near the upper edge of the blower port is a first side edge (not shown in the drawing). The side edge near the lower edge of the blower opening of the first baffle plate 10 is a second side edge (not shown in the drawing), and the first rotary shaft 12 faces the first side edge. To form a first surface (not shown in the drawing), the first rotation shaft extends toward an upper edge of the blower opening to form a second surface (not shown in the drawing), The included angle between one surface and the second surface is α. When the air conditioner 100 operates in the direct wind prevention mode, the range of α is 40°<α≦55°. In this state, the wind speed of the air coming out of the air duct is relatively low and the air volume is not large. Since the wind is blocked by the first baffle plate 10, it is avoided that the wind is blown directly on the human body. The wind diffuses around the first baffle plate 10 to make the wind more gentle. It is more easily accepted by the user and brings a comfortable feeling to the user.

Further, when the air conditioner 100 is in the direct air flow prevention mode, when the range of α is 40°<α≦55°, the distance between the first side edge and the upper edge of the blower opening is M. Yes, and the range of M is 70 mm-85 mm, or, when the air conditioner 100 operates in a soft breeze mode, the distance between the second side edge and the lower edge of the blower opening is N. Moreover, the range of N is 25 mm-35 mm. When the air conditioner 100 is in the direct wind prevention mode, the action of the first baffle plate 10 makes it easier to soften the air coming out of the air duct. At this time, when the air blown from the air conditioner 100 diffuses along the first air guide plate 10, the wind speed and the air volume coming out from the air blower opening are reduced to be blown directly to the user from the air conditioner air blower. It is easy to avoid feeling cold/warm air.

As shown in FIG. 2, the air conditioner further has a cooling/heating mode, and when the air conditioner operates in the cooling/heating mode, the first baffle plate is completely retracted from the blower port, The range of α is 65°≦α≦90°. In the embodiment of the present application, the second operation mode is the cooling/heating mode, and the first baffle plate 10 and the second baffle plate 20 rotate to a position substantially parallel to the blowing direction of the blower duct. At this time, a side edge of the first baffle plate 10 near the upper side of the blower port is a first side edge, and a side edge of the first baffle plate 10 near a lower side of the blower port is a second side edge. The first rotary shaft 12 extends toward the first side edge to form a first surface, and the first rotary shaft 12 extends toward the upper edge of the blower opening to form the second surface. And the angle between the first surface and the second surface is α. That is, with the state in which the first air guide plate completely closes the blower opening as the initial position, the angle at which the first air guide plate 10 rotates about the first rotation axis 12 from the initial position is α, When the range of the rotation angle α of the first baffle plate 10 is 65°≦α≦90°, in this state, inside the air duct of the first baffle plate 10 and the second baffle plate 20. The hindrance to the wind is relatively weak. As a result, the speed and volume of the air coming out of the air duct are relatively large, which is convenient for quickly changing the temperature of the surrounding environment.

Furthermore, when the air conditioner operates in the cooling/heating mode, the range of the distance M between the first side edge and the upper edge of the blower opening is 95 mm-110 mm. Alternatively, when the air conditioner operates in the cooling/heating mode, the range of the distance N between the second side edge and the lower edge of the blower opening is 25 mm-45 mm. In the present embodiment, when the air conditioner 100 is operated in the cooling/heating mode and the range of α is 65°≦α≦90°, the range of M is 95 mm-110 mm, or the range of N is 25 mm. -45 mm. This makes it easier to adjust the wind speed and air volume coming out of the air outlet. At this time, since the first air guide plate 10 has little obstruction to the air blow of the air conditioner 100, the wind speed of the air coming out of the air blow duct is increased, the air volume is increased, and the temperature in the room is quickly adjusted.

Further, in the embodiment of the present application, the first air guide plate 10 is provided with air diffuser holes 11 penetrating the first air guide plate 10 in the thickness direction.

Further, the length of the air diffuser hole 11 in the opening direction is equal to the thickness of the first air guide plate 10. Alternatively, the length of the air diffuser hole 11 in the opening direction is larger than the thickness of the first air guide plate 10. The diameter of the air diffuser hole 11 gradually increases along the direction from the inside of the first air guide plate 10 to the outside of the first air guide plate 10. The structure is simple, and it is convenient for the wind of the air duct to diffuse from the air diffuser holes 11 of the first air guide plate 10 to the surroundings.

The present application further proposes a control method of the air conditioner 100. The air conditioner 100 is the air conditioner 100. The air conditioner 100 includes a direct air flow prevention mode and a cooling/heating mode. The air conditioner can switch between the direct air flow prevention mode and the cooling/heating mode. When operating in the wind protection mode, the first baffle plate blocks a part of the air outlet, the first rotating shaft extends toward the first side edge to form a first surface, and the first rotating shaft Represents a second surface extending toward the upper edge of the blower opening, and the angle between the first surface and the second surface is α, the range of α is 40°<α≦55°. Yes, when the air conditioner operates in the cooling/heating mode, the first air guide plate is completely retracted from the air outlet, and the range of α is 65°≦α≦90°. For the specific structure of the air conditioner 100, refer to the above-mentioned embodiment and will not be described here in detail.
