Specifically, in the embodiment, the method for controlling the rotation of the air deflector 40 and the working condition of the air guiding component according to the preset cooling mode of the indoor unit of the air conditioner includes: when the preset refrigeration mode of the indoor unit of the air conditioner is default refrigeration, controlling the air deflector 40 to rotate to a first preset angle, and controlling the flexible part 10 of the air guiding component to be in an avoiding position; when the preset refrigeration mode of the indoor unit of the air conditioner is soft air refrigeration, the air deflector 40 is controlled to rotate to a second preset angle, and the flexible part 10 of the air guiding component is controlled to be in an air guiding position; and the angle value of the second preset angle is greater than that of the first preset angle. By adopting the structure, the preset refrigeration mode of the indoor machine of the working strip can be conveniently started according to the requirement and operated according to the default preset refrigeration mode or the soft wind mode, and the angle value of the second preset angle is larger than that of the first preset angle, so that the flexible part 10 can move conveniently in the soft wind mode, and the air deflector 40 and the flexible part 10 are prevented from interfering with each other.

In this embodiment, when the preset cooling mode of the air conditioning indoor unit is soft air cooling, the method for controlling the flexible member 10 to be in the air guiding position further includes: when the soft air refrigeration is in a static mode, acquiring a preset windshield, and controlling a fan 60 of the indoor unit of the air conditioner to operate on the preset windshield; when the soft air cooling is in the dynamic mode, the fan 60 of the indoor unit of the air conditioner is controlled to change between different rotating speeds. By adopting the method, different air outlet modes can be provided conveniently, so that the comfort requirement of a user can be better met.

Specifically, the method for controlling the fan 60 of the indoor unit of the air conditioner to change between different rotating speeds when the soft air cooling is in the dynamic mode comprises the following steps: acquiring the running time T; when T < T0, controlling the fan 60 to rotate at the rotating speed V₁Running; when T is more than or equal to T0, controlling the fan 60 at the rotating speed V₁Rotational speed V₂And a rotational speed V₃Change the rotation speed of the fan 60 and control the running time of the fan 60 at different rotation speeds to be less than the preset time T₁(ii) a Wherein, V₁＞V₂＞V₃. By adopting the method, the fan 60 can be conveniently ensured to operate at a high rotating speed so as to ensure enough air output; after the operation reaches the preset time T0, the rotating speed of the fan 60 is switched, so that enough air output can be ensured, the fan 60 can be prevented from operating at a high rotating speed for a long time, the energy consumption of the fan 60 is reduced, and the air outlet comfort is also ensured. Under the condition of different rotating speeds, the flexible structure can realize different soft wind effects, and the flexible body is guided to realize different air supply heights through the intelligent automatic change of the rotating speed of the fan 60, so that the soft wind effect of high and low fluctuation is achieved, and dynamic soft wind is realized.

In the present embodiment, when the rotation speed of the fan 60 is V₁When the air guiding component is used, the included angle between the flexible part 10 of the air guiding component and the air guiding plate 40 is alpha; when the rotational speed of the fan 60 is V₂When the air guiding plate is used, the included angle between the flexible part 10 and the air guiding plate 40 is beta; when the rotational speed of the fan 60 is V₃When the air guiding plate is used, the included angle between the flexible part 10 and the air guiding plate 40 is gamma, and alpha is more than beta and more than gamma. Controlling the fan 60 at a rotational speed V₁Rotational speed V₂And a rotational speed V₃The method for transforming between further comprises: controlling the rotational speed V of the fan 60₁So that 60 DEG > alpha > 30 DEG; controlling the rotational speed V of the fan 60₂So that 60 DEG > beta > 30 DEG; controlling the rotational speed V of the fan 60₃Such that 60 > gamma > 30. By adopting the structure, the flexible part 10 can be ensured to have effective air supply height when three different rotating speeds are achieved by controlling alpha, beta and gamma within the range, so that cold air can be better prevented from blowing people directly, and the flexible part can be usedThe swinging action of the wind-dispelling device 10 can realize the wind softening and wind dispelling.

Specifically, the control method in this embodiment is as follows: a user starts a preset refrigeration mode, and can select three modes of default refrigeration, static soft wind refrigeration (a static mode in soft wind refrigeration) and dynamic soft wind refrigeration (a dynamic mode in soft wind refrigeration). When the default refrigeration is started, the air deflector 40 is opened to a first preset angle (corresponding to the air deflector 40 being at a general default position), and the flexible part 10 is rolled and does not extend out; when the static soft wind preset refrigeration mode is started, the air deflector 40 is opened to a second preset angle (corresponding to the lowest position of the air deflector 40), the flexible part 10 extends out of the winding box 30, airflow flows through the flexible part 10 to generate different pressure differences, and the flexible part 10 automatically supports the airflow to present an airflow flowing state with a high middle part and low two sides, so that the soft wind effect is realized; when the dynamic soft wind refrigeration is started, the air deflector 40 is opened to a second preset angle (corresponding to the lowest position of the air deflector 40), the rotating speed of the fan 60 is set to be V, and the flexible body is guided to realize different air supply heights through the automatic change of the rotating speed of the fan 60, so that the soft wind effect with fluctuating height is realized.

Specifically, the method for converting the rotation speed of the fan 60 in the embodiment is as follows: three rotating speeds are provided, the mode 1 is that the rotating speed of the fan 60 is V₁At this time, the wind deflector is an ultra-strong wind deflector, the included angle between the flexible body and the wind deflector 40 is alpha, and the air supply height is the highest; mode 2, fan 60 rotates at speed V₂At this time, the wind shield is high, the included angle between the flexible body and the wind deflector 40 is beta, and the air supply height is centered; mode 3, the rotational speed of the fan 60 is reduced to V₃At this time, the wind damper is adopted, the included angle between the flexible body and the wind deflector 40 is gamma, and the air supply height is lower; wherein, 60 degree is more than alpha, more than beta, more than gamma, more than 30 degree, 1500rpm is more than V₁＞V₂＞V₃＞800rpm。

Specifically, the operation time of the air conditioner is set to T, and after the dynamic soft wind preset refrigeration mode is turned on, the fan 60 drives the flexible body to shake according to the mode 1. T is more than or equal to T₀The fan 60 then rotates back and forth between modes 1, 2, and 3 (either randomly or according to a function curve). And each mode has a running time of T₁. Wherein T is less than or equal to 5min₀10min or less, preferably T₀Is 5 min; t is less than or equal to 5min₁Less than or equal to 20min, preferably 10 min.
