  • a following step is able to be implemented: when the controller receives a turn-off signal, the second swing louvers operate to be in the fully closed state.
  • a control method of an air conditioner includes following steps in such ways that:
  • the positive effect of the present application is that: in the air conditioner and the control method of the air conditioner of the present application, the swing louvers are first fully opened to reset when the air conditioner is powered on, and then the swing louvers are controlled to be fully closed, so that the swing louvers are in a fully-closed initial state after the air conditioner is powered on, which avoids a deviation between an actual swing and a required swing of the swing louvers due to changes in initial positions of the swing louvers when the air conditioner is turned on.
  • FIG. 1 is a flow chart of a control method of an air conditioner, in accordance with the present application.
  • orientations or positional relationships indicated by terms “center”, “upper”, “lower”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer” and the like are based on orientations or positional relationships shown in the drawings, which are used merely for convenience of description and simplifying the description of the present application, but not to indicate or imply that the referred devices or elements must have a specific orientation, or be constructed and operated in a particular orientation. Therefore, these terms should not be construed as limitations to the present application.
  • first and second are merely used for a purpose of description and should not be construed as indicating or implying the relative importance, or implicitly indicating the number of referred technical features. Thus, features defined by “first” and “second” may explicitly or implicitly include one or more of the features.
  • installation In the description of the present application, it will be noted that term “installation”, “communication”, or “connection” is to be understood broadly. For example, it may be a fixed connection, a detachable connection, or an integral connection; and it may be a direct connection, or may be an indirect connection through an intervening medium, and may be internal communication between two elements. Specific meanings of the above terms in the present application may be understood by those skilled in the art according to specific situations.
  • the present application provides an air conditioner, and the air conditioner includes an indoor unit having a first air outlet.
  • First swing louvers capable of controlling an opening-closing range of the first air outlet are disposed at the first air outlet.
  • the first swing louvers are in a fully closed state when the first swing louvers close the first air outlet, the first swing louvers are in a fully open state when the first swing louvers are opened to enable the first air outlet to reach a maximum air output volume, and when the first swing louvers are between the fully closed state and the fully open state, a state of the first swing louvers is defined as a free state.
  • a controller is disposed in the indoor unit, which includes a memory and a processor.
  • a computer program is stored in the memory, and when the program is executed by the processor, a following step is able to be implemented in such way that: when the indoor unit is powered on, the first swing louvers operate to be in the fully open state to be reset, and then operate to be in the fully closed state.
  • swing louvers at an air outlet of an air conditioner are generally in the close state before the air conditioner is powered on, the swing louvers of the indoor unit are easily moved by mistake due to the position and the environment of the indoor unit, which may cause changes in initial positions of the swing louvers.
  • By adding processes of resetting the swing louvers to fully open positions and then closing the swing louvers simultaneously when the air conditioner is powered on it is ensured that the swing louvers may be in the fully closed state after the air conditioner is powered on. In these processes, it takes approximately 10 seconds for the swing louvers to switch from the fully open state to the fully closed state generally, and thus the addition of the processes may not cause an excessive increase of the startup time.
  • the first swing louvers at the first air outlet can prevent dust from entering and people from accidentally touching electrical components and moving components in the air conditioner only if the first swing louvers are in the fully closed state.
  • the air conditioner is turned off, the swing louvers move to fully closed positions, and a fan motor also stops operating at the same time.
  • the draught fan may prolong its operation for a period of time, the air may be blocked and loud noise may be generated if the swing louvers are immediately closed at the time.
  • a following step is able to be implemented in such way that: when the controller receives a turn-off signal, the first swing louvers are reset to be in the fully open state, and operate to be in the fully closed state after a preset time.
  • the preset time may be 5 seconds, that is, when the controller receives the turn-off signal, the first swing louvers at the first air outlet reset to the fully open positions and wait for 5 seconds, and then the first swing louvers are closed simultaneously.
  • first swing louvers in the present application include a plurality of first swing louvers arranged in a front-to-rear order.
  • First swing louver(s) at a rear part are stacked on first swing louver(s) at a front part when the first swing louvers are in the fully closed state.
  • the program in the memory is executed by the processor, a following step is able to be implemented in such way that: when the controller receives a turn-on signal, the first swing louver(s) at the rear part operate to be in the fully open position(s) to be reset, and the first swing louver(s) at the front part operate to be in the fully open position(s) to be reset after waiting for a preset time.
  • Adding the above process may bring benefits as follows.
  • the controller When the controller is turned on, the plurality of swing louvers start to move synchronously. If the swing louvers are moved mistakenly by a user and are not in the fully closed positions before the air conditioner is turned on, inaccurate stop positions of the swing louvers are easily to be caused.
  • the swing louvers are reset to the fully open positions first, and then the swing louvers are made to stop at positions required by the user through the controller, it is avoided that stop positions of air deflectors are inaccurate due to the mistaken movement by the user.
  • the swing louver(s) at the front part and the swing louver(s) at the rear part are in the fully closed state
  • the swing louver(s) at the rear part are stacked on the swing louver(s) at the front part.
  • the swing louvers may interfere with each other in the swing process due to a same moving speed, which may cause the swing louver(s) at the front part and the swing louver(s) at the rear part to collide with each other.
  • the swing louver(s) at the front part are set to wait for the preset time and then start to be fully opened, the mutual interferences between the swing louvers may be effectively avoided.
  • the preset time may be 1 second.
  • the swing louvers are generally controlled by a stepping motor to rotate, and the stepping motor may lose some pulses when the swing louvers changed their rotation direction.
  • the pulse losses may be accumulated after multiple swings, which may cause the swing louvers to fail to swing in parallel.
  • a following step is able to be implemented in such way that: when the controller receives a swing signal, the first swing louvers swing according to an instruction from the controller, and it is determined that whether a swing number of the first swing louvers reaches a preset number; if yes, the first swing louvers are controlled to operate to be in the fully open state to be reset, and the swing number is recalculated after the first swing louvers are reset.
