The indoor unit may also be used in the technical field of air conditioning equipment, that is, according to another aspect of the present application, an air conditioner is provided, including an indoor unit, where the indoor unit is an indoor unit in the foregoing embodiment.
According to another aspect of the present application, there is provided a method of controlling an air conditioner, the method being used for controlling the air conditioner in the above embodiment, the method comprising the steps of: the indoor unit is started, the indoor unit is adjusted to any one of a mute gear, a low wind gear, a middle and low wind gear, a middle and high wind gear, a high wind gear and a super strong wind gear, the controller controls the upper fan blade 21 and the lower fan blade 31 to operate at the highest rotating speed of the gear for a first preset time, and after the first preset time, the rotating speed of the upper fan blade 21 is gradually reduced from the high rotating speed adjusting gear to the low rotating speed adjusting gear.

Specifically, the air conditioner can help to realize rapid refrigeration and rapid heating of the air conditioner, on the other hand, the comfortable air supply effect of the air conditioner can be greatly improved, the problem caused by the operation of the air conditioner at a fixed rotating speed is avoided, on the other hand, the comfort of human body refrigeration/heating is realized by adjusting the rotating speed of the inner fan, and the power of the air conditioner can be reduced by a method of improving the rotating speed of the compressor.
In the up-down air outlet air conditioner provided by the application, the air inlet of the air conditioner is provided with 2 coaxial through-flow blades, the air inlet enters the cavity after passing through the through-flow blades, and the air outlet of the air conditioner is also provided with 2 through-flow blades, after the upper motor and the lower motor are simultaneously opened, the air inlet is provided with negative pressure, the air outlet is provided with positive pressure, the negative pressure is within a certain range, the air is pushed to flow to the positive pressure, the air quantity is increased, and the rapid refrigerating and heating capacities of the air conditioner are improved.
Meanwhile, the scheme can improve the heat exchange of the air conditioner by starting the motor at the air inlet, but not by means of improving the operation frequency of the compressor, and the operation power of the inner motor is smaller than that of the compressor of the air conditioner. Through upper and lower air-out control, adjust air inlet, air-out rotational speed, increase the amount of wind for heat transfer speed improves user's travelling comfort, shortens heat transfer time. Meanwhile, the control of the upper air outlet and the lower air outlet enables the air outlet quantity to be more selected, and the electrodeless air supply is realized.
By adopting a unique up-down air inlet control method, the air outlet is quickly adjusted according to the remote control setting requirement of a user, and the quick refrigerating and heating effects of a room are ensured. Meanwhile, after the air is blown for 3min, the rotating speed of the upper motor can be automatically adjusted, gradual change type air supply is ensured, and the air blowing is softer and more comfortable. When a user operates according to any wind gear, after the lower motor is started, the rotating speed of the wind gear is set according to a program, the upper motor and the lower motor are operated within the first 3min of the starting of the motor respectively according to a certain set maximum air volume rotating speeds Nsi and Nxi (wherein s represents an upper fan, x represents a lower fan, i represents different wind gear settings, such as mute gear=0, low wind gear=1, middle and low wind gear=2, middle wind gear=3, middle and high wind gear=4, high wind gear=5 and super strong wind gear=6), the upper motor and the lower motor are operated according to a preset rotating speed, so that the optimal heat exchange effect can be obtained after the starting of the motor, and the quick refrigeration and quick heating effects of the whole machine are ensured. After 3min, if the user is in the default mode of the current wind gear (mute gear/low wind gear/…/super wind gear), the rotation speed of the upper motor is circularly changed from Nsi to 0 and 0-Nsi in an ascending and descending mode. When the user automatically adjusts the remote controller, the remote controller equally divides different wind gears, as shown in fig. 4, taking mute gear as an example, mute gear is also divided into stepped gears such as L1/L2/L3/L4/L5/L6, etc. Wherein L1 to L6 respectively correspond to 1/6Nsi, 2/6Nsi, 3/6Nsi, 4/6Nsi, 5/6Nsi and 6/6Nsi of air inlet.
Similarly, for low/medium/high/super high, if the wind is in automatic mode, the upper motor speed is cyclically incrementally and incrementally varied from Nsi to 0 and 0-Nsi. When the user automatically adjusts the remote controller, the remote controller equally divides different sound files, and each wind file is also divided into ladder gears such as L1/L2/L3/L4/L5/L6. Wherein L1 to L6 respectively correspond to 1/6Nsi, 2/6Nsi, 3/6Nsi, 4/6Nsi, 5/6Nsi and 6/6Nsi of air inlet.
When a certain specific wind gear is in an automatic mode or is manually adjusted by a user, the lower motor continuously executes preset rotating speed Nxi, so that smooth and omnibearing coverage of air outlet of the whole internal machine can be realized, the influence of air inlet rotating speed adjustment on air quantity is not as obvious as that of an air outlet, the purpose of electrodeless air supply can be realized, and the comfort requirement can be ensured.
In addition, if the user adjusts the wind gear halfway, the lower inner fan speed will run according to the set lower fan speed corresponding to the adjusted wind gear within 3min before adjustment, and after 3min, if the automatic mode is adopted, the upper motor is circularly and incrementally and progressively changed according to the set speed of 0-Nsi, and the lower motor for controlling wind outlet runs according to the set Nxi speed.
Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
