Specifically, as shown in fig. 2 and 3, the casing may be a cylindrical housing, and the front panel 1 and the rear fender 2 are both arc-shaped plates. The first air inlet 21 of the rear fender 2 may be installed with an air inlet grill. As shown in fig. 4, an air outlet 11 is formed in the middle of the front panel 1, an air outlet guide plate 9 may be installed at the air outlet 11, and an air outlet direction of the air outlet 11 may be controlled by the air outlet guide plate 9. Two sides of the front panel 1 are respectively provided with a second air inlet 12, a decorative plate 3 is arranged in the casing corresponding to each second air inlet 12, the decorative plate 3 can slide in the casing, for example, the decorative plate can slide along the width direction or the height direction of the second air inlet 12, and then the size of the shielding area of the decorative plate 3 for the second air inlet 12, namely, the opening degree of the second air inlet 12 can be adjusted.
When the air conditioner is in a normal mode, the basic use requirement can be met through the air inlet amount of the first air inlet 21, so that the second air inlet 12 can be completely shielded by the decorative plate 3, the opening degree of the second air inlet 12 is zero, and air only flows in from the first air inlet 21.

According to the control method of the air conditioner indoor unit, the second air inlets 12 are additionally arranged on the two sides of the front panel 1, meanwhile, the opening degree of the second air inlets 12 is adjusted by the decorative plate 3, so that a larger air inlet area can be obtained when the air conditioner is switched to an ultra-strong mode to operate, the problem that the air inlet area of the existing air conditioner cannot be completely utilized due to the design reasons of the cross-flow fan and the air channel of the existing air conditioner is solved, the air supply power can be reduced, and the air conditioner energy efficiency is improved. Simultaneously based on variable controllable air inlet region for the air conditioner can realize the regional adjustment of multiple air inlet according to different demands and different environment, and then reaches different air-out distances, different cold and hot effects. The control method of the air conditioner indoor unit realizes flexible utilization of the air inlet area of the air conditioner, improves the air inlet quantity and the air outlet quantity, reduces the power, and improves the cooling and heating effect and the efficiency of the whole machine.
Further, as shown in fig. 5 and 6, the decorative plate 3 includes a baffle 31 and a purification plate 32 connected to each other, and the baffle 31 and the purification plate 32 are sequentially slidable to the second air inlet 12. Specifically, the baffle plate 31 and the purge plate 32 may be integrally connected. In the embodiment, mainly taking the decorative plate 3 sliding along the width direction of the second air inlet 12 as an example for explanation, the height of the baffle plate 31 and the height of the purification plate 32 are the same, and the baffle plate 31 and the purification plate 32 are arranged in parallel along the width direction of the second air inlet 12, and the width of the baffle plate 31 and the width of the purification plate 32 are both greater than or equal to the width of the second air inlet 12. The baffle 31 is a solid plate and mainly functions to close or partially close the second air inlet 12. The purification plate 32 is provided with a purification component, which may be a High Efficiency Air Filter (HEPA Filter) or an Intense Field Dielectric Filter (IFD Filter). Among them, the HEPA filter is mainly used for collecting particle dust and various suspended matters with the particle size of more than 0.5 μm, and the common filter material is superfine glass fiber and the like, and has the advantages of high filtering efficiency, low resistance and large air volume. The IFD filter utilizes dielectric material to form strong electric field for the carrier, and dielectric material forms cellular cavity microchannel, and the dielectric parcel electrode slice forms strong electric field in the passageway, through the ionized air, makes the dust take the static, and the high-efficient filter core that uses electrified electrode adsorbs again to reach purifying effect.
As shown in fig. 6, the section AB (or section a 'B') corresponds to the baffle 31 and the second wind inlet 12, and the section BC (or section B 'C') corresponds to the purification plate 32. When the air conditioner operates in the normal mode, the baffle 31 completely closes the second air inlet 12, and when the air conditioner operates in the super-strong mode, the decorative plate 3 slides towards the first air inlet 21, that is, the decorative plates 3 on the left and right sides in fig. 6 all slide upwards, so that the baffle 31 gradually slides out from the second air inlet 12, and meanwhile, the purification plate 32 gradually slides to the second air inlet 12, and the specific sliding distance can be determined according to the refrigeration or heating temperature requirement or the air purification requirement. Because the purifying plate 32 is made of air permeable filtering material, when the purifying plate 32 slides to the second air inlet 12, it can not only increase the air intake of the air conditioner, but also play a role in purifying the indoor air.
In addition, the decorative plate 3 can also slide along the height direction of the second air inlet 12, the baffle plate 31 and the purification plate 32 are arranged in parallel along the height direction of the second air inlet 12, and the rest arrangement and the use method are similar to those of the above embodiment and are not described again here.
Further, as shown in fig. 7, the super strong mode further includes:
when Δ T>T1When the air enters the shell, all the air enters the shell after passing through the purification plate 32;
when T is2＜ΔT≤T1When a is1% of the intake air enters the housing (1-a) after passing through the purification plate 321%) is blocked by the baffle 31;
when T is3＜ΔT≤T2When a is2% of the intake air enters the housing (1-a) after passing through the purification plate 322%) is blocked by the baffle 31;
when Delta T is less than or equal to T3When a is3% of the intake air enters the housing (1-a) after passing through the purification plate 323%) is blocked by the baffle 31;
wherein, 0 < T3＜T2＜T1，0＜a3％＜a2％＜a1Percent is less than 100 percent. Specifically, a1% of 50 to 80%, a2% of 30 to 50%, a3% is 20-30%. T is1At a temperature of 2 ℃ to 4 ℃ T2At 1 to 2 ℃ and T3Is 0 ℃ to 1 ℃.
In a specific embodiment, a1% is 2/3, a2% is 1/3, a3% 1/4; t is1At 3 ℃ T2At 1.5 ℃ and T3Is 0.5 ℃. That is, as shown in fig. 6, when the interface between the baffle 31 and the purification plate 32 slides upwards for the arc length AB, the purification component on the purification plate 32 completely acts on the air entering the air, and at this time, the air supply amount is the largest, and the purification effect is the most obvious. When the boundary surface of the baffle 31 and the purification plate 32 slides upwards for 2/3AB arc length, the purification component of 2/3 part on the purification plate 32 acts, so that the functions of increasing the intake air amount and purifying air are achieved, the noise is reduced by 1dB, and the noise reduction function is achieved. The 1/3 portion of the purge plate 32 works to reduce noise by 2dB when the boundary surface between the baffle 31 and the purge plate 32 is slid upwards for an arc length of 1/3 AB. When the boundary surface of the baffle 31 and the purge plate 32 is slid upward for an arc length of 1/4AB, the portion 1/4 of the purge plate 32 acts as a purge assembly, reducing noise by 2.5 dB. Therefore, the provision of the purge plate 32 can simultaneously function to increase the flow, reduce noise, and purge air.
