As shown in fig. 1 and 2, an air outlet 2 assembly provided in this embodiment 1 includes a panel housing 1. In the view shown in fig. 1, an air outlet 2 is formed on the front side of the panel housing 1, and circular through holes are formed on the left and right sides of the panel housing 1, respectively.
In the present embodiment 1, the number of the axial fans 4 is preferably two, and the two axial fans 4 are respectively installed in the two circular through holes on the side surface of the panel housing 1.

In embodiment 1, the axial flow fan 4 can blow out the air flowing out of the air outlet 2 to the outside of the axial flow fan 4, and the air supply area can be enlarged. Meanwhile, compared with the existing air outlet 2 assembly, the air outlet 2 assembly provided by the invention eliminates the wind sweeping blades, so that the influence of the wind sweeping blades on the airflow field of the air duct can be eliminated, and the noise of the air conditioner indoor unit can be reduced.
Preferably, the through holes on the left and right sides of the panel housing 1 may be coaxially arranged so as to realize the coaxial arrangement of the axial fans 4 on the both sides of the air inlet.
Of course, in the present embodiment 1, the number of the axial fans 4 is not particularly limited, and the specific number of the axial fans 4 may be adjusted according to the technical index and the experimental result of the model machine at the time of development of a specific project.
In embodiment 1, the arrangement of the axial fans 4 is not limited, and may be a circular array, a square array, or the like. For example, if the noise is small, a plurality of small axial fans 4 can be selectively installed, and the noise value of a single fan can be reduced, thereby reducing the overall noise value, while the total air volume is kept unchanged.
Further, in embodiment 1, the axial flow fan 4 is preferably capable of blowing out the air flowing out of the air outlet 2 to the outside of the axial flow fan 4, and the axial flow fan 4 is preferably capable of sucking air outside the axial flow fan 4 into the air outlet 2.

Meanwhile, the axial flow fan 4 can mix indoor air with air out of the air outlet 2 so as to make air supply softer.
Specifically, as shown in fig. 2, the axial flow fan 4 of the present embodiment 1 may include two axial flow protection covers 41 that are fastened to each other, and a mounting area is provided between the two axial flow protection covers 41, in which an axial flow blade 42 and an axial flow motor 43 for driving the axial flow blade 42 to rotate forward or reverse are mounted.
In embodiment 1, the axial flow motor 43 of the axial flow fan 4 is preferably an axial flow motor 43 capable of performing forward and reverse rotation so as to be capable of driving the blades to blow out wind forward and reverse.
Specifically, in this embodiment 1, two axial fans 4 are installed on circular through holes on both sides of the panel housing 1, and both the two axial fans 4 are opposite to the air outlet 2, so that the indoor air and the cold air blown out from the air outlet 2 can be mixed, part of the cold air blown out from the air duct can be sucked away, and the direction angle of the cold air blown out from the air duct can be changed by using the indoor air.
In this embodiment 1, each axial flow fan 4 faces the air outlet 2 from the side, and the axis of the axial flow fan 4 passes through the air outlet 2, and the wind blown out by the axial flow blades 42 and the wind of the air outlet 2 are in a vertical relationship, so that the two wind can meet to mix the indoor air with the cold wind blown out by the air duct, and part of the cold wind blown out by the air duct can be sucked away, and the direction angle of the cold wind blown out by the air duct can be changed by using the indoor air.
It should be understood that the rotation speeds of the through-flow fan blades 3 and the axial-flow fan 4 have a certain matching relationship, that is, the rotation speed of the through-flow fan blades 3 is increased, the rotation speed of the interior of the axial-flow fan 4 is correspondingly increased, and the changing degree is matched according to specific design requirements.
In embodiment 1, the size of the axial flow blades 42 inside the axial flow fan 4 can be adjusted according to technical specifications developed in a specific project. That is, the larger the air volume shift of the air blower device internal unit is, the larger the corresponding axial flow blade 42 is required to be in order to provide stronger wind force, so that the wind blown out by the cross flow blade 3 can be blown.
On the contrary, the smaller the air volume gear of the air supply device inner machine is, the smaller the corresponding axial flow blade 42 is required to be so as to provide smaller wind force, thereby being capable of scattering the wind blown out by the cross flow blade 3.
In the air outlet 2 assembly provided in this embodiment 1, compared with the existing air outlet 2 assembly, the air outlet 2 assembly provided in this embodiment 1 eliminates the wind sweeping blades, adds the axial fan 4, and blows out the air outlet at the air outlet 2 to the outside of the axial fan 4 through the axial fan 4, so as to enlarge the air supply area. Meanwhile, the air sweeping blade on the air outlet 2 assembly can eliminate the influence of the air sweeping blade on the air flow field of the air duct, and further can reduce the noise of the indoor unit of the air conditioner.
Example 2
To the problem that current air supply equipment's air outlet 2 air supply area is little, this embodiment 2 provides an air supply equipment, not only can carry out soft air supply, but also possess bigger air supply area to and can reduce the noise of air supply equipment inner unit.
The embodiment 2 provides an air supply device, which comprises an inner machine and the air outlet 2 assembly, wherein the air outlet 2 assembly is arranged at the air outlet 2 of the air duct of the inner machine.
Further, in the air outlet 2 assembly, axial fans 4 are arranged on both sides of the air outlet 2;
the air supply device has three air supply modes of soft air supply, air supply and air sweeping,
in the soft wind mode, the axial fans 4 at the two sides of the air outlet 2 suck the air at the outer sides of the axial fans 4 into the air outlet 2, and the air is mixed with the air outlet at the air outlet 2 and then blown out;
in the air supply mode, the axial fans 4 at the two sides of the air outlet 2 simultaneously blow out part of the air outlet 2 to the outer sides of the axial fans 4;
in the wind sweeping mode, the axial flow fan 4 at one side of the air outlet 2 sucks air outside the axial flow fan 4 into the air outlet 2, and the air is mixed with air outlet at the air outlet 2 and then blown out, and the axial flow fan 4 at the other side of the air outlet 2 does not work.
Further, each axial flow fan 4 is fitted with a regulator for regulating the rotational speed of the axial flow motor 43 of the corresponding axial flow fan 4.
Preferably, the regulator of the axial flow fan 4 is wirelessly connected with the corresponding axial flow fan 4.
Preferably, the regulators of the two axial fans 4 are integrated into one regulating controller.
The air supply device provided in embodiment 2 may be an air conditioner, an indoor unit, a wall-mounted air conditioner, a cabinet air conditioner, or the like.
As shown in fig. 3 to 6, the air supply device provided in embodiment 2 has three modes, namely a gentle air mode, a large-area air supply mode and an angle-adjustable left-right air sweeping mode.
Specifically, as shown in fig. 3, when the air supply device provided in embodiment 2 is in the soft air mode, the axial flow blades 42 of the axial flow fans 4 on the left and right sides of the air outlet 2 rotate forward, so that the axial flow fans 4 can convey indoor air to the air outlet 2 and mix with and blow out cold air in the air duct of the air supply device.
At this time, the mixed air becomes soft and does not irritate the human body; and the rotating speed of the axial flow fan 4 in the soft wind mode can be regulated to control the softness of the air outlet.
As shown in fig. 4, when the air supply device provided in embodiment 2 is in the large-area air supply mode, the axial flow blades 42 of the axial flow fans 4 on the left and right sides of the air outlet 2 are reversed, so that part of cold air of the air outlet 2 is delivered to two sides of the air supply device through the axial flow fans 4, and the air supply area is increased, and meanwhile, a certain soft air effect is also achieved.
It should be understood that in the present embodiment 2, in the large-area air blowing mode, the higher the rotation speed of the axial flow fan 4, the stronger the both-side air blowing and the weaker the front air blowing.
When the air supply device provided in embodiment 2 is in the angle-adjustable left-right wind sweeping mode, one of the axial fans 4 is operated, and the other axial fan 4 is not operated. That is to say,
as shown in fig. 5, when the air supply device provided in embodiment 2 is in rightward air supply, the axial flow fan 4 on the right side of the air outlet 2 is not operated, and the axial flow fan 4 on the left side of the air outlet 2 is operated.
At this time, the axial flow fan 4 at the left side of the air outlet 2 conveys the indoor air to the air outlet 2, and mixes the indoor air with the cold air in the air duct of the air supply device and then blows the air.
As shown in fig. 6, when the air blowing apparatus provided in this embodiment 2 is in the leftward blowing, the right axial flow fan 4 is operated, and the left axial flow fan 4 is not operated.
