[ example 3 ]

First, in the air outlet assembly a provided in this embodiment, as shown in fig. 9 and 10, the air outlet assembly a includes a first enclosing plate (not shown in the figure and located in a direction parallel to the paper surface), a second enclosing plate (not shown in the figure and located in a direction parallel to the paper surface), and an air baffle 31; the first enclosing plate and the second enclosing plate are oppositely arranged at intervals; at least two wind isolation plates 31 are arranged between the inner walls of two opposite sides of the first enclosing plate and the second enclosing plate at intervals, and an air duct is enclosed between the two adjacent wind isolation plates 31 and the first enclosing plate and the second enclosing plate; two adjacent air partition plates 31 are elastically connected at the air inlet side and the air outlet side of the air duct; at least one air partition plate 31 in the two air partition plates 31 on the outermost side is rotatably connected between the inner walls of the two opposite sides of the first enclosing plate and the second enclosing plate through a rotating shaft 32, and the air inlet side and the air outlet side of the air duct are elastically deformed when the air partition plates 31 connected with the rotating shaft 32 rotate around the rotating shaft 32.

For example, in order to realize that two adjacent wind-shielding plates 31 are elastically connected at the wind inlet side and the wind outlet side of the wind channel, the plurality of wind-shielding plates 31 may be elastically connected at the wind inlet side and the wind outlet side of the wind channel by elastic ropes (not shown) or springs (not shown); two ends of all the wind isolation plates 31, which are close to the first enclosing plate and the second enclosing plate, on the air inlet side of the air duct are respectively connected with an elastic rope or a spring; two ends of all the wind isolation plates 31 close to the first enclosing plate and the second enclosing plate on the air outlet side of the air duct are respectively connected with an elastic rope or a spring. Therefore, when one wind-isolating plate 31 rotates around the rotating shaft 32, the distance between the two adjacent wind-isolating plates 31 of the air duct on the air inlet side and the air outlet side can be adjusted through the elastic rope or the spring, so that the opening degree of the air inlet and the air outlet can be adjusted.

As a preferred embodiment of the air outlet assembly a provided in this embodiment, in order to achieve that two adjacent air baffles 31 are elastically connected at both the air inlet side and the air outlet side of the air duct, a plurality of air baffles 31 may be elastically connected at both the air inlet side and the air outlet side of the air duct through elastic strips, where one end of one elastic strip on all air baffles 31 close to the first enclosing plate extends from the air inlet side to the air outlet side of the air duct, and the other end of the other elastic strip on all air baffles 31 close to the second enclosing plate extends from the air inlet side to the air outlet side of the air duct. It will be appreciated that in this case the first and second webs may be provided as resilient strips. The purpose of elastic deformation between the adjacent air partition plates at the air inlet side and the air outlet side can also be achieved when one air partition plate 31 at the outermost side rotates around the rotating shaft 32 of the air partition plate.

In order to realize that the air partition plate 31 connected with the rotating shaft 32 generates elastic deformation on the air inlet side and the air outlet side of the air duct when rotating around the rotating shaft 32, one implementation mode is that one air partition plate 31 in the two air partition plates 31 at the outermost side is fixedly connected with a rotating shaft 32, and the other air partition plate 31 is used for being fixed on the mounting plate, so when the air partition plate 31 connected with the rotating shaft 32 rotates around the rotating shaft 32, if the distance between the two adjacent air partition plates 31 at the air inlet side of the air duct is increased, the distance between the two adjacent air partition plates 31 at the air outlet side of the air duct is reduced, namely, the opening degree of the air inlet of the air duct is increased under the action of the elastic force, and the opening degree of the air outlet of the air duct is reduced. Wherein, the mounting plate can be a framework of an indoor unit of an air conditioner.

In another implementation manner, as shown in fig. 9 and 10, two outermost wind-dividing plates 31 are respectively fixedly connected with a rotating shaft 32.

Wherein fig. 9 shows: the air partition plate 31 on the leftmost side rotates anticlockwise around the rotating shaft 32, and the air partition plate 31 on the rightmost side rotates clockwise around the rotating shaft 32, so that the opening of the air inlet of the air duct is increased, and the opening of the air outlet is reduced. Further, fig. 10 shows: the air partition plate 31 on the leftmost side rotates clockwise around the rotating shaft 32, and the air partition plate 31 on the rightmost side rotates anticlockwise around the rotating shaft 32, so that the opening degree of the air inlet of the air duct is reduced, and the opening degree of the air outlet is increased.

So, the air baffle 31 that is connected with pivot 32 can make the air inlet side in wind channel and air outlet side produce elastic deformation when rotating around its pivot 32 to the air inlet grow in wind channel air outlet diminishes simultaneously, perhaps the air inlet in wind channel diminishes while air outlet grow, thereby has realized the regulation of the air intake of air-out subassembly A and the aperture size of air outlet.

Therefore, the motor drives the disc to rotate and simultaneously drives the push rod to swing, then the push rod 33 drives the partition plate to rotate around the rotating shaft 32 of the partition plate, and then electric power adjustment of the opening degree of the air outlet of the air duct is achieved.

Then, in the air conditioner indoor unit 01 provided by the present embodiment, the air conditioner indoor unit 01 includes the air outlet assembly a according to any one of the foregoing embodiments. Therefore, the air conditioner indoor unit 01 can increase the wind speed and the wind power by reducing the opening of the air outlet under the condition that the rotating speed of the fan of the air conditioner indoor unit 01 is low through adjusting the opening of the air outlet assembly A, so that the wind speed is increased and the feeling of cold wind and hot wind of people is improved in an energy-saving mode without adjusting the rotating speed of the fan.

[ example 4 ]

In order to solve the above problems in the prior art, that is, to solve the problem that the size of the air outlet of the existing air conditioner indoor unit cannot be adjusted, and when the difference between the indoor actual temperature and the target temperature is small, the size of the air outlet of the air conditioner indoor unit cannot be changed to adjust the air outlet speed and save energy, the embodiment provides a control method of the air conditioner indoor unit and the air conditioner indoor unit.

So, can realize reaching the air-out speed of guaranteeing air conditioner indoor through the aperture that reduces the air outlet under the less and lower condition of fan rotational speed of temperature difference value to increase the wind speed and improved people to cold wind and hot-blast impression through more energy-conserving mode.
