In addition, the air conditioner needs to reasonably control the air flow direction according to the movement mechanism of cold/hot air flow, so that air conditioner wind acts on a target area, the utilization efficiency of cold/heat is enhanced, and the energy consumption is reduced. For example, when the existing up-down air-out air conditioner heats and runs, single down air supply or up-down simultaneous air supply is adopted, the air quantity of the up-down air-out mode is large, but the efficiency of the fan is higher when the up-down air supply is performed, but because of structural limitation, the air outlet of the heating upper air port needs to undergo flow direction change of more than 110 degrees to enable the hot air to be pressed down, so that the resistance of the air channel is increased, the air quantity is reduced, and good heating effect is difficult to realize. Meanwhile, when the user feels strong in blowing sense, the heating is started without wind sense, so that poor heat dissipation of a machine is easily caused, or if the air guide angle is adjusted upwards, hot air is seriously floated, the heat utilization rate of a human body activity area is low, the heating effect is poor, and the energy consumption is increased.
Because the air conditioner in the prior art cannot meet the air supply requirements under different scenes, and the air supply modes are not diversified enough, the user experience is poor and other technical problems are caused, the invention designs an air conditioner air supply structure, an air conditioner and a control method.

When the air flows out from the single air outlet, the third partition plate 10 and the second partition plate 8 are closed, the air deflector of the first air outlet 5 is opened, indoor air subjected to heat exchange enters the second air channel 4 from the centrifugal fan, the air flows enter the left air channel and the right air channel respectively through the flow dividing piece 9, and finally the two air flows are converged and then are sent out from the first air outlet 5, so that the top air outlet is realized, and the cold air avoidance is realized; or, as shown in fig. 3, the first air outlet 5 and the third air outlet 11 are controlled to be opened, and the second air outlet 7 is controlled to be closed; at this time, the air-conditioner air-out structure is in an up-down air-out mode.
When the air conditioner is in a heating mode, as shown in fig. 6, the first air outlet 5 and the third air outlet 11 are controlled to be closed, and the second air outlet 7 is controlled to be opened, at this time, the air outlet structure of the air conditioner is in a single full-open side air outlet mode, or, as shown in fig. 5, the first air outlet 5 is controlled to be closed, and the second air outlet 7 and the third air outlet 11 are controlled to be opened. At this time, the air-conditioner air-out structure is in a full-open side air-out and lower air-out mode,
in some embodiments, when the air conditioner is initially operated for cooling/heating, the first air outlet 5 is opened, the second air outlet 7 and the third air outlet 11 are closed, or the first air outlet 5 and the third air outlet 11 are opened, and the second air outlet 7 is closed. In the technical scheme, in the early stage of refrigeration/heating operation, the human body activity area in the early stage of heating is heated up rapidly, meanwhile, cold and hot stimulation is carried out on the human body under the cold or hot bias environment to improve comfortableness, the left and right air guide directions of the two second air outlets 7 are regulated, the switching of wind gathering and wide-angle environment-friendly air supply can be realized, the temperature of the near field, the far field and each corner is controlled differently, and the accurate and efficient air supply is carried out. When the air outlets are fully opened at the two upper sides of the single air conditioner, the first partition plate 6 and the third partition plate 10 are closed, the second partition plate 8 is fully opened, and indoor air subjected to heat exchange flows out from the two second air outlets 7 after passing through the left air duct and the right air duct, so that two-side air supply is realized. The second air outlet 7 is provided with an air deflector which adopts a conventional air outlet air deflector structure, the air deflector of the second air outlet 7 is controlled or remotely controlled in a refrigerating and heating mode, the angle of the air deflector is upward during refrigeration, the preferable angle is 0-60 degrees, cold air is prevented from directly blowing a human body, the air deflector is downward during heating, the preferable angle is 0-45 degrees, hot air floating is restrained, and the heat utilization rate of an active area is improved. When the air supply is fully opened at two sides and the air is discharged downwards, the third partition board 10 is opened, compared with the air discharge of the first air outlet 5 at the top, the length of the second air duct 4 is shortened, the resistance is reduced, the upper air discharge air volume ratio is increased, the heating hot air is more beneficial to downwards pressing, the heat utilization rate of the human body activity area is improved, and the energy-saving comfortable operation is realized.
In some embodiments, as shown in fig. 7 and 8, when the air conditioner is in a low air-shift mode or the target active area is far away from the air conditioner, in order to allow cool air/hot air to be supplied to the active area, it is necessary to increase the air speed by decreasing the area of the air outlet, and when the air conditioner is in a low air-shift mode or the target active area is far away from the air conditioner, the first air outlet 5 and the third air outlet 11 are closed, the second air outlet is at least partially opened, or the first air outlet 5 is closed, the second air outlet is at least partially opened, and the third air outlet 11 is opened.
In some embodiments, when the first partition 6 and the second partition 8 are disposed in the second air duct 4; when the first air outlet 5 and the third air outlet 11 are closed and the second air outlet is at least partially opened, further comprising the steps of,
a detection step of detecting the farthest air supply distance dc of the air conditioner and the distance dg between the target active area and the air conditioner;
a judging step of judging a relationship between dc and dg;
a control step of controlling the second partition plate 8 to move when dc is greater than or equal to (dg+k), thereby increasing the air outlet area of the second air outlet 7; namely, if the furthest air supply distance of the current air conditioner is far greater than the target air supply distance, controlling the second partition plate 8 to move downwards, increasing the air outlet area of the second air outlet 7, and reducing the air flow rate;
when dc is greater than or equal to dg and less than (dg+k), controlling the second separator 8 to stop; i.e. the current conditioned air can be delivered to the target area exactly, the second partition 8 is controlled to maintain the state operation.
When dc is smaller than dg, controlling the second partition plate 8 to move, so as to reduce the air outlet area of the second air outlet 7; where k is supply air distance compensation. The air conditioner farthest air supply distance dc is determined by detecting the current air conditioner wind shield, and the air conditioner farthest air supply distance dc is predicted by combining the position of the side air outlet air deflector. That is, the current air conditioner has shorter air supply distance, the second partition plate 8 is controlled to move upwards, the air outlet area of the second air outlet 7 is reduced, the air flow speed is increased, and the air supply distance is improved.
Referring to fig. 9 in combination, when the air-conditioning air-out structure of the present invention is in a single full-open side air-out mode, the air-conditionerCloud picture of air blowing vertical plane speed distribution of full-open air supply at two sides of heating high air baffle, and air quantity is 1100m 3 And the air outlet temperature is 48 ℃, the air supply declination angle is 23 degrees, the hot air can fall to the ground in a downward pressing way, the coverage range is wide, and the room heat utilization rate is high. Referring to fig. 10 in combination, when the air outlet structure of the air conditioner of the present invention is in a single half-open side air outlet mode, the air volume is reduced to 750m 3 At/h, the hot air coverage is narrowed, but the air pressure effect is still good.
It will be readily appreciated by those skilled in the art that the above advantageous ways can be freely combined and superimposed without conflict.
