  • those skilled in the art may set the specific value of the first preset temperature by themselves according to the actual use situation, as long as the indoor cold air will accumulate in the lower part when the indoor temperature is lower than or equal to the first preset temperature.
  • step S 104 if the controller judges that the obtained indoor temperature is higher than the first preset temperature and lower than the second preset temperature, it indicates that the indoor temperature at this point is appropriate.
  • the air conditioner controls both the first air inlet and the third air inlet to be opened, so that the air after heat exchange can fully exchange heat with a large amount of indoor air before being blown out, thereby ensuring the comfort of air supply to the greatest extent.
  • the controller can control the first air blocking member to no longer block the first air inlet and control the third air blocking member to no longer block the third air inlet; in this case, the air inducing device can introduce the indoor air through the air inducing holes provided in the first air inducing panel 231 , the air inducing holes provided in the second air inducing panel 232 and the air inducing holes provided in the third air inducing panel 233 altogether, so as to effectively increase the induced air volume of the air inducing device.
  • step S 105 if the controller judges that the obtained indoor temperature is higher than or equal to the second preset temperature, it indicates that the indoor temperature at this point is relatively high.
  • the air conditioner needs to reduce the induced air volume of the air inducing device, thereby effectively lowering the temperature of outflow air; at the same time, in order to also avoid the problem of uneven heat distribution in the room caused by a large amount of hot air accumulating in an upper part of the room, the air conditioner controls the first air inlet to be opened and the third air inlet to be closed, so that the air inducing device can introduce more air from the upper part of the room; therefore, the air conditioner can perform heat exchange more evenly to improve the user's heat exchange experience maximally.
  • the controller does not control the first air blocking member to block the first air inlet, so that the indoor air can be introduced by the air inducing device through the air inducing holes provided in the first air inducing panels 231 ; at the same time, the controller can also control the third air blocking member to block the third air inlet, so that the indoor air cannot be introduced by the air inducing device through the air inducing holes provided in the third air inducing panels 233 .
  • the air inducing device can introduce indoor air through the air inducing holes provided in the first air inducing panels 231 and the second air inducing panels 232 ; that is, the air inducing device can mainly introduce the air in the upper part of the room.
  • those skilled in the art may set the specific value of the second preset temperature by themselves according to the actual use situation, as long as the indoor hot air will accumulate in the upper part when the indoor temperature is higher than or equal to the second preset temperature.
