Wherein, as can be understood by those skilled in the art, the adjustment of the air outlet direction is realized by adjusting the air outlet angle of the air guide assembly, taking a hanging type air conditioner as an example, the air guide assembly comprises an air guide blade close to an indoor fan and an air guide plate for closing an air outlet, the air guide blade is used for adjusting the left and right air outlet angles, the air guide plate is used for adjusting the upper and lower air outlet angles, the plane where the air outlet is located is taken as a reference plane, the included angle between the air guide blade and the reference plane is determined as a first air outlet angle for the air guide blade, the axis of the air guide plate is determined as a first point on any transverse section of the air conditioner, the outer end of the air guide plate is determined as a second point, the point opposite to the outer end of the air outlet on the air guide plate is a third point, the connecting line between the first point and the second point is further noted as a first connecting line, and the connecting line between the, and determining an included angle between the first connecting line and the second connecting line as a second air outlet angle.

The air conditioner is characterized in that the air conditioner is adjusted to a first air outlet direction or a second air outlet direction by adjusting a first air outlet angle and/or a second air outlet angle, wherein the first air outlet direction can be obliquely upward air outlet to avoid a user activity area, air is further fed through an air inlet of the air conditioner to form air path circulation, and when the condition parameters of the indoor unit meet the adjustment conditions, namely the room can be heated, the first air outlet angle and/or the second air outlet angle are/is continuously adjusted to the second air outlet direction.

The second air outlet direction may be determined based on a historical usage record, for example, the air outlet direction with a large number of user uses is determined as the second air outlet direction.

The second air outlet direction may also be determined based on the detection of the vital signs, for example, by providing an infrared detection device to detect the area where the user is located, so as to determine the direction opposite to the area where the user is located as the second air outlet direction.

It is worth explaining, as a most reliable detection mode, when the room temperature and the pipe temperature of the indoor heat exchanger satisfy the cold air prevention condition, the indoor fan is controlled to be opened again, and the air guide assembly is adjusted to the first air outlet direction, the first air outlet direction of the air guide assembly can be one direction away from the user for the indoor fan to drive the air flow direction, and can also be two directions away from the user for the indoor fan to drive the air flow, and the air guide direction can be defined at will, because the purpose of this application can all be realized, therefore, all should be within the protection scope of this application.

The technical personnel in the field can understand that the cold air prevention condition is the condition that the indoor fan blows out cold air when the air conditioner heating mode is started, the heating mode is a heating mode with a cold air prevention function and can also be understood as a rapid heating mode, and the working condition parameters comprise running time, working condition temperature and the like.

In the above technical solution, the method further comprises: if the indoor heat exchanger enters the heating mode and the room temperature and/or the pipe temperature of the indoor heat exchanger meet/meets the cold air prevention condition, the electric auxiliary heat device is controlled to be started to heat the indoor heat exchanger through the circulating air path, wherein the electric auxiliary heat device is arranged between the indoor heat exchanger and the indoor fan.

In this technical scheme, when detecting to get into the mode of heating, gather the pipe temperature of room temperature and/or indoor heat exchanger, when the pipe temperature that detects room temperature and/or indoor heat exchanger satisfies cold wind prevention condition, the electric auxiliary heating device is opened in the control again, utilize the electric auxiliary heating device to generate heat and heat indoor heat exchanger gradually, in order to accelerate heating speed and increase heating capacity, through setting up the electric auxiliary heating device between indoor heat exchanger and indoor fan, combine the circulation wind path can heat indoor heat exchanger fast, in order to prevent that the temperature of electric auxiliary heating device lasts to rise, the risk that the too high damage that causes of electric auxiliary heating device temperature has been reduced, the security and the stability of product use have been improved.

In the above technical solution, the air conditioner further includes an outdoor heat exchanger and a throttling device disposed between the indoor heat exchanger and the outdoor heat exchanger, and further includes: and if the air conditioner detects that the air conditioner enters a heating mode and the room temperature and/or the pipe temperature of the indoor heat exchanger meet/meets the cold air prevention condition, controlling to close the throttling device.

The fifth temperature threshold and the second temperature threshold are comparison reference values of the room temperature, and the fifth temperature threshold and the second temperature threshold have a return difference, so that temperature fluctuation is prevented.

The first temperature threshold, the fourth temperature threshold and the third temperature threshold are comparison reference values of the tube temperature of the indoor heat exchanger, and the fourth temperature threshold and the third temperature threshold are also return differences of the tube temperature.

The fifth temperature threshold represents a threshold value for the temperature of the room that no longer requires auxiliary heating by the electric auxiliary heating device, and the temperature of the room rises to this temperature, indicating that the temperature of the room is already high and that it is not necessary to turn on the electric auxiliary heating device.

The second temperature threshold (a comparison value of the room temperature) and the third temperature threshold (a comparison value of the pipe temperature of the indoor heat exchanger) are used for judging whether the first air outlet direction is necessary to be controlled and adjusted and controlling the electric auxiliary heating device to be started, and when the room temperature is lower than the second temperature threshold, the room temperature is lower, and the electric auxiliary heating device can be started; on the contrary, the electric auxiliary heat does not need to be turned on.

The third temperature threshold, which is usually 32 ℃, is higher than the temperature threshold, which indicates that the tube temperature is higher at this time, and the tube temperature can be increased to the fourth temperature threshold in a short time, i.e. the air outlet direction does not need to be adjusted.

The first time threshold value represents a time threshold value for controlling the pipe temperature of the indoor heat exchanger to rapidly rise to normal heating after the throttling device is closed. The second time threshold represents a time threshold for controlling the refrigerant to flow to the indoor heat exchanger so that the refrigerant is accumulated in the indoor heat exchanger as much as possible.

The third time threshold represents a time threshold for controlling the evacuation of the compressor.

The fourth time threshold represents a time threshold of an opening time interval of the second control valve and the third control valve.
