The embodiment of the utility model provides a swing blade capable of solving the problem of short air supply distance of an air conditioner, thereby improving heat exchange efficiency and accelerating indoor cooling or heating speed and an air conditioner indoor unit.

Fig. 1 is a schematic structural view of a swing blade of an air conditioner according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 to 5, the embodiment of the present utility model provides a swing blade of an air conditioner, which includes an air duct 110, the air duct 110 having an air guide passage 111. The air guide rail 112 is provided with a convex air guide rail 112 on the channel wall of the air guide channel 111, and the air guide rail 112 is spiral.

In the working process, the fan of the air conditioner operates, and the air generated by the fan enters from the air inlet of the air duct 110 through the air outlet of the air conditioner and is blown indoors through the air outlet of the air duct 110. Because the air duct 110 is internally provided with the raised spiral air guide rail 112, the air can be changed into the air blown outwards in a spiral shape after passing through the air guide rail 112.

In this embodiment, since the air passing through the air duct 110 is blown out in a spiral shape, the air conditioner can blow the air blown out through the air duct 110 farther, so that the air blown out by the air conditioner can reach a place farther from the air conditioner in the room, thereby realizing a longer air supply distance. In a shorter time, cool air or hot air emitted by the air conditioner is uniformly distributed indoors, so that air circulation exchange in a larger space range is realized, the circulation heat exchange efficiency of the air is improved, the indoor cooling or heating speed is improved, and the energy consumption of the air conditioner is reduced.

In some embodiments of the present utility model, as shown in fig. 1, the number of air guide rails 112 is plural, and the plural air guide rails 112 are uniformly distributed on the channel wall of the air guide channel 111. The helix angles of the plurality of wind guide rails 112 are equal and do not interfere with each other.

In this embodiment, the wind entering the duct 110 may contact more of the wind guide rails 112 at the same time than a single wind guide rail 112. After the air outlet of the air conditioner passes through the plurality of air guide rails 112, the rotation speed is higher, so that the air outlet of the air conditioner moves forwards in a more stable rotation manner.

In some embodiments of the present utility model, the air guiding channel 111 has an air inlet at one end and an air outlet at the other end. The cross-sectional area of the air inlet is larger than that of the air outlet. The air guide channel 111 is a tapered channel that gradually becomes smaller along one end of the air inlet to one end of the air outlet.

In this embodiment, the cross-sectional area of the air outlet is smaller than that of the air inlet, so that the air collecting effect is achieved. When the wind in the wind guide channel 111 goes from the air inlet to the air outlet, the air flow is accelerated in the process of being blown out of the air outlet of the wind guide channel 111, so that the wind can reach a more distant place.

Further, in some embodiments of the present utility model, the air duct 110 is a tapered cone that tapers from one end of the air inlet to one end of the air outlet.

In this embodiment, the cross section of the wind guiding channel 111 of the conical cylinder is an arc surface, so that disturbance of the wind guiding channel 111 to airflow is reduced. And after the air outlet of the air conditioner enters from the air inlet with large caliber of the conical cylinder, the air flows out from the air outlet with small caliber at a larger flow speed, so that the air can be blown to a longer distance from the air outlet of the air conditioner.

In some embodiments of the present utility model, the wind guide rail 112 is wound with a gradually increasing distance along the flow direction of the air flow, i.e. along the direction from the air inlet end to the air outlet end. Gradually increasing the wind-up distance of the wind guide rail 112 can increase the speed of the air discharged from the air conditioner after passing through the wind guide drum 110. The wind-up distance is the pitch and lead of the wind-guiding rail 112.

In some embodiments of the utility model, as shown in FIG. 1, the air rail 112 is wrapped at least 3/4 of a turn around the channel wall.

In some embodiments of the present utility model, as shown in fig. 2, at least one side of the air duct 110 is provided with an air guiding blade 130, and the air guiding blade 130 is on the same plane with the axis of the air duct 110.

Preferably, the air guide blades 130 are arranged on two opposite sides of the air guide cylinder 110, and the two air guide blades 130 and the axis of the air guide cylinder 110 are on the same plane.

In the working process, part of the air outlet of the air conditioner enters the air duct 110 and is blown out, and the other part of the air outlet of the air conditioner passes through the air guide blades 130 from the outside of the air duct 110 and is blown out.

In the present embodiment, the wind guide blades 130 are located at both sides of the wind guide 110 for adjusting the wind direction of wind blown out from the outside of the wind guide 110. When the wind direction of the wind in the air duct 110 is independently adjusted, the wind direction of part of the wind is still uncontrolled, and the using feeling is prevented from being influenced.

In some embodiments of the present utility model, the outer surface of the air duct 110 is provided with another air guide rail 112. The air guide rail 112 inside the air guide duct 110 is on the same side as the air guide rail 112 outside the air guide duct 110. The air guide tube 110 is provided with the air guide rail 112 inside and outside, so that more air is influenced by the air guide rail 112, and the air is blown into a room in a spiral shape.

The embodiment of the utility model also provides an air conditioner indoor unit, which comprises an air conditioner air outlet and a swing blade assembly 100 arranged in the air conditioner air outlet. The lobe assembly 100 includes at least one first lobe, which is a lobe of any of the embodiments described above.

In some embodiments of the present utility model, as shown in fig. 4, the swing blade assembly 100 further includes a second swing blade 120, and the second swing blade 120 is a plurality. The air duct 110 and the second swing blades 120 are alternately arranged in sequence along the length direction of the air outlet of the air conditioner. The air-conditioner air-out part passes through the first swing blade and part passes through the second swing blade 120, so that the air blown indoors has both far air and near air. Is beneficial to the rapid indoor temperature reduction or heating.

In some embodiments of the utility model, the air conditioner air outlet is a heat exchange air outlet. For example, the indoor unit of the air conditioner is a wall-mounted indoor unit of the air conditioner or a vertical indoor unit of the air conditioner, and only one air outlet is a hot air exchanging air outlet.

In other embodiments of the present utility model, the air conditioner indoor unit has a heat exchange air outlet and a uniform air outlet, and the air conditioner air outlet is the uniform air outlet. The even wind air outlet is arranged at one side of the hot wind exchanging air outlet.

In other embodiments of the present utility model, an air conditioning indoor unit has a fresh air outlet and a fresh air outlet, and the air conditioning outlet is the fresh air outlet.

In other embodiments of the present utility model, the air conditioner air outlet includes a heat exchange air outlet and a non-heat exchange air outlet.

Specifically, the air conditioning indoor unit further includes a first column casing 10. The first column casing 10 has a vertical column shape. The front side of the first column casing 10 is provided with a heat exchange air outlet 12. The swing blade assembly 100 is disposed at the hot air exchanging outlet 12 for guiding the air outlet direction. After flowing through the air duct 110, the heat exchange air is blown to the indoor environment from the heat exchange air outlet 12, so that the cooling and heating of the indoor environment are accelerated.

Further, as shown in fig. 5, the air conditioning indoor unit further includes a second casing 20. The second column casing 20 has a vertical column shape, and the second column casing 20 is arranged in a lateral direction with the first column casing 10. The front side of the second casing 20 is provided with a non-heat exchange air outlet 22 for blowing out non-heat exchange air flow. The swing blade assembly 100 is disposed at the non-heat exchange air outlet 22 for guiding the air out. Alternatively, the non-heat exchange air flow may be one or more of indoor air, fresh air flow, purified air flow, humidified air flow or water washing air flow, which is used for auxiliary regulation of indoor environment.

Further, a non-heat exchange air outlet 22 for homogenizing air is formed between the second cylindrical shell 20 and the first cylindrical shell 10, which may also be referred to as a homogenizing air outlet 13.

The swing blade assembly 100 is disposed at an air outlet of the air-homogenizing air outlet 13 for guiding the air-out direction.

During operation, the first column casing 10 and the second column casing 20 alternatively or simultaneously turn on the supply air. When the heat exchange air outlet 12 and/or the non-heat exchange air outlet 22 are/is used for air outlet, the indoor air in the uniform air outlet 13 is driven to flow forwards by virtue of the negative pressure effect and passes through the air duct 110 so as to be mixed into the air outlet air flow of the first column casing 10 or the second column casing 20, and a drainage air mixing effect is formed. Compared with the heat exchange air flow, the temperature of the air mixing air flow is closer to the room temperature, the comfort is higher, the wind sense is softer, the air quantity and the air speed are increased, and the air supply distance is longer. Particularly, after the air blown out from the second casing 20 is blown into the room through the duct 110, a more powerful air mixing effect can be achieved, so that the air flow is closer to the room temperature. When the second casing 20 blows out the conditioning air flows such as fresh air flow, purified air flow, humidified air flow or water washing air flow, the conditioning air flows can be mixed with the heat exchange air flow earlier and more, the mixing rate is enhanced, and the conditioning air flows are better diffused to all parts of a room.
