As shown in FIG. 1 to FIG. 6 , an embodiment of the present application provides a control method for an indoor unit of an air conditioner. As shown in FIGS. 2 to 5 , the indoor unit of the air conditioner includes a casing, and the casing includes a front panel 1 and a rear guard Panel 2, the middle of the front panel 1 is provided with an air outlet 11, the rear guard plate 2 is provided with a first air inlet 21, both sides of the front panel 1 are provided with a second air inlet 12, and the casing is also provided with a second air inlet 12. The decorative plate 3 corresponding to the air inlet 12 is slidably connected to the casing to adjust the opening of the second air inlet 12 . As shown in Figure 1, the control method of the indoor unit of the air conditioner includes a super strong mode, and the super strong mode includes:

Obtain the set temperature and ambient temperature, and calculate the temperature difference ΔT between the set temperature and the ambient temperature;

When ΔT>T ₁ , all the second air inlets 12 are opened;

When ΔT≦T ₁ , the second air inlet 12 is partially opened.

Specifically, as shown in FIGS. 2 and 3 , the casing may be a cylindrical casing, and both the front panel 1 and the rear shield 2 are arc-shaped panels. The first air inlet 21 of the rear fender 2 may be provided with an air inlet grille. As shown in FIG. 4 , an air outlet 11 is opened in the middle of the front panel 1 , and an air outlet guide 9 can be installed at the air outlet 11 , and the air outlet direction of the air outlet 11 can be controlled by the air outlet guide 9 . There is also a second air inlet 12 on both sides of the front panel 1. Corresponding to each second air inlet 12, there is also a decorative plate 3 in the casing. The decorative plate 3 can slide in the casing, for example, along the second air inlet. The width direction or height direction of the air inlet 12 slides, and then the size of the shielding area of the second air inlet 12 by the decorative plate 3 can be adjusted, that is, the opening degree of the second air inlet 12 can be adjusted.

When the air conditioner is running in the normal mode, the air intake through the first air inlet 21 can meet the basic usage requirements, so the decorative panel 3 can completely block the second air inlet 12. At this time, the opening of the second air inlet 12 At zero, air only flows in from the first air inlet 21 .

When the air conditioner is running in the super mode, the air inlet area can be increased by opening the second air inlet 12, the air intake air volume can be increased, and the air outlet air volume can be increased.

In the control method for the indoor unit of the air conditioner provided in this embodiment, the second air inlets 12 are added on both sides of the front panel 1, and the opening of the second air inlet 12 is adjusted by the decorative plate 3, so that the air conditioner is switched to the ultra-high When running in strong mode, a larger air intake area can be obtained, which solves the problem that the air intake area of the existing air conditioner cannot be fully utilized due to the design of the cross-flow fan and its air duct, thereby reducing the air supply. power and improve the energy efficiency of air conditioners. At the same time, based on the variable and controllable air inlet area, the air conditioner can adjust various air inlet areas according to different needs and different environments, thereby achieving different air outlet distances and different cooling and heating effects. The control method of the air conditioner indoor unit realizes the flexible utilization of the air inlet area of the air conditioner, increases the air intake air volume and the air outlet air volume, reduces the power, and improves the cooling and heating effect and the efficiency of the whole machine.

Further, as shown in FIGS. 5 and 6 , the decorative panel 3 includes a connected baffle 31 and a purification panel 32 , and the baffle 31 and the purification panel 32 can slide to the second air inlet 12 in sequence. Specifically, the baffle 31 and the purification plate 32 may be integrally connected. This embodiment is mainly described by taking the sliding of the decorative plate 3 along the width direction of the second air inlet 12 as an example. 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, and the purification component may adopt a high-efficiency air filter (High Efficiency Particulate Air Filter, HEPA filter for short) or an Intense Field Dielectric (IFD filter for short). Among them, the HEPA filter is mainly used to capture particulate dust above 0.5μm and various suspended solids. The commonly used filter materials are ultra-fine glass fiber, etc., which have the advantages of high filtration efficiency, low resistance and large air volume. The IFD filter uses a dielectric material as a carrier to form a strong electric field, the dielectric material forms a honeycomb hollow microchannel, and the dielectric wraps the electrode sheet to form a strong electric field in the channel. The filter element is adsorbed to achieve the purification effect.

As shown in Figure 6, the AB section (or A'B' section) in the figure corresponds to the baffle 31 and the second air inlet 12, and the BC section (or B'C' section) corresponds to the purification plate 32. When running in the normal mode, the baffle 31 completely closes the second air inlet 12 , and when running in the super mode, the decorative panel 3 slides toward the first air inlet 21 , that is, the decorative panels 3 on the left and right sides in FIG. 6 slide upwards Therefore, the baffle 31 gradually slides out from the second air inlet 12, while the purification plate 32 gradually slides to the second air inlet 12. The specific sliding distance can be determined according to the cooling or heating temperature requirements or air purification requirements. Since the purification plate 32 is made of a breathable filter material, when the purification plate 32 slides to the second air inlet 12, the air intake volume of the air conditioner can be increased, and the indoor air can be purified.

In addition, the decorative plate 3 can also slide along the height direction of the second air inlet 12, and the baffle 31 and the purification plate 32 are arranged side by side along the height direction of the second air inlet 12. It is not repeated here.

Further, as shown in Figure 7, the super mode further includes:

When ΔT>T ₁ , all the intake air enters the casing after passing through the purification plate 32;

When T ₃ <ΔT≦T ₂ , a ₂ % of the intake air passes through the purification plate 32 and then enters the casing, and (1-a ₂ %) of the intake air is blocked by the baffle 31 ;

When ΔT≦T ₃ , a ₃ % of the intake air passes through the purification plate 32 and enters the casing, and (1-a ₃ %) of the intake air is blocked by the baffle 31 ;

Among them, 0<T ₃ <T ₂ <T ₁ , and 0<a ₃ %<a ₂ %<a ₁ %<100%. Specifically, a ₁ % is 50% to 80%, a ₂ % is 30% to 50%, and a ₃ % is 20% to 30%. T1 is ₂ °C to 4°C, T2 is ₁ °C to ₂ °C, and T3 is 0°C to 1°C.

In a specific embodiment, a1% is _2/3 , a2% is _1/3 , a3% is _1/4 ; T1 is ₃ °C, T2 is 1.5°C, and _T3 is _0.5 °C. That is, as shown in FIG. 6 , when the interface between the baffle 31 and the purification plate 32 slides up the arc length of the AB segment, the purification components on the purification plate 32 completely act on the air entering the air, and the air supply volume is the largest at this time, and the purification effect is The most obvious. When the interface between the baffle 31 and the purification plate 32 slides upward by 2/3 of the arc length of the AB segment, the purification components of the 2/3 part of the purification plate 32 work, which not only increases the air intake and purifies the air at this time. It also reduces the noise by 1dB, which plays a role in noise reduction. When the interface between the baffle 31 and the purification plate 32 slides upward by 1/3 of the arc length of the AB segment, the 1/3 part of the purification components on the purification plate 32 works, reducing the noise by 2dB. When the interface between the baffle 31 and the purification plate 32 slides upward by 1/4 of the arc length of the AB segment, the 1/4 part of the purification assembly on the purification plate 32 works, reducing the noise by 2.5dB. Therefore, by disposing the purifying plate 32, the functions of increasing the flow, reducing noise and purifying the air can be simultaneously achieved.
