(3) hand-off process of the wind direction of blow out air when circulation pattern refrigeration operation
Referring to Fig. 5 flow chart to circulation pattern refrigeration operation when the hand-off process of the wind direction of blow out air that carries out carry out Explanation.
The user of air conditioner selects automatic mode, refrigeration mode or dehumidification mode as the fortune of air conditioner by remote controler Rotary-die type, select circulation pattern as flow pattern after, indicate the operation start of air conditioner, be automatic mode in operation mode In the case of, when further selecting refrigeration operation or dehumidifying operating by control unit 80, start a succession of processing below.Separately Outside, in the following description, to simplify the explanation, the user of air conditioner is not accounted in midway change operation mode or air-flow The case where mode.
Firstly, in step sl, switching mechanism control unit 81 controls the movement of wind direction switching mechanism 30, so that The wind direction of the blow out air blown out from blow-off outlet 27 becomes the 1st direction.Specifically, switching mechanism control unit 81 switches wind direction The barrier driving (not shown) of mechanism 30 is assigned with motor and being indicated, makes the 1st overhead gage 40, the 2nd overhead gage 50 and lower baffle plate 60 Attitudes vibration is posture when the 1st direction is blown out.
Then, in step s 2, when determining whether to have passed through initial switching blowing out since blow out air is to the 1st direction Between.The initial switching time is the preset time.The initial switching time does not limit, still, e.g. 10 minutes.Work as judgement When to have passed through the initial switching time the blowout since blow out air is to the 1st direction, S3 is entered step.It is being determined as from blowout Air starts to have blown out before have passed through the initial switching time to the 1st direction, and step S2 is repeated.
Control permission portion 82 is configured to, first in air conditioner indoor unit 10 after the operation start of circulation pattern refrigeration operation In the case that the endurance period for starting blowout blow out air to the 1st direction has been more than the initial switching time, allow to switch Mechanism controls portion 81 is controlled such that blow out air is blown out to the 2nd direction to the movement of wind direction switching mechanism 30.Therefore, exist In step S3, control permission portion 82 allows switching mechanism control unit 81 to be controlled such that the movement of wind direction switching mechanism 30 Blow out air is blown out to the 2nd direction.
Temperature unevenness presumption unit 85 is configured to, and is more than initial switching in the time that blow out air is continuously blown out to the 1st direction In the case where time, it is estimated as producing temperature unevenness in air-conditioning object space RS.Therefore, in step s3, temperature is uneven Presumption unit 85 is estimated as producing temperature unevenness in air-conditioning object space RS.
Then, in step s 4, control permission portion 82 allows switching mechanism control unit 81 to the dynamic of wind direction switching mechanism 30 It is controlled, detects or deduce the generation temperature unevenness in air-conditioning object space RS, therefore, switching mechanism control unit 81 Blow out air is blown out to the 2nd direction to be controlled such that the movement of wind direction switching mechanism 30.Specifically, switching mechanism control Portion 81 processed assigns the barrier driving (not shown) of wind direction switching mechanism 30 with motor and indicates, makes the 1st of wind direction switching mechanism 30 The attitudes vibration of overhead gage 40, the 2nd overhead gage 50 and lower baffle plate 60 is posture when the 2nd direction is blown out.
Then, in step s 5, determine whether to have passed through the 2nd direction blowing out since blow out air is to the 2nd direction and blow Setting time out.2nd direction blowout setting time is to be redefined for eliminate the temperature unevenness of air-conditioning object space RS Time.2nd direction blowout setting time does not limit, still, e.g. 2 minutes.When being determined as from blow out air to the 2nd direction Start to have blown out have passed through the 2nd direction blowout setting time when, enter step S6.It is being determined as from blow out air to the 2nd direction Start to have blown out before have passed through the 2nd direction blowout setting time, step S5 is repeated.
In step s 6, switching mechanism control unit 81 is controlled such that blowout is empty to the movement of wind direction switching mechanism 30 Gas is blown out to the 1st direction.Specifically, switching mechanism control unit 81 uses the barrier driving (not shown) of wind direction switching mechanism 30 Motor assigns instruction, appearance when blowing out the 1st direction of attitudes vibration of the 1st overhead gage 40, the 2nd overhead gage 50 and lower baffle plate 60 State.In addition, though illustration omitted, still, in step s 6, control permission portion 82 forbids switching mechanism control unit 81 so that blowing The mode that air is blown out to the 2nd direction out is controlled (permission for releasing control) to the movement of wind direction switching mechanism 30.
Then, in the step s 7, determine whether air-conditioning object space RS with the 1st stipulated time persistently meets rated condition. Here rated condition is that the temperature that room temperature sensor 71 detects is predetermined temperature or less and space humidity sensor is examined The humidity measured is the such condition of specified humidity or less.Additionally, it is preferred that using being estimated as in predetermined temperature and specified humidity Meet the value of the comfort of the user of air conditioner.For example, do not limit, still, in the step s 7, decision space temperature sensing The temperature that device 71 detects is that the humidity that below the set temperature that remote controler inputs and space humidity sensor 72 detects is Whether 70% state below continues 60 minutes or more.It is being determined as that air-conditioning object space RS persistently meets with the 1st stipulated time In the case where rated condition, S8 is entered step.It is being determined as that air-conditioning object space RS persistently meets regulation article with the 1st stipulated time Before part, the judgement of step S7 is repeated.
