Abstract

PURPOSE:To improve an air conditioning efficiency and air conditioning comfortability by freely altering or setting a fluctuating limit angle of both reciprocating directions of a wind direction deflector by a user in response to the using state of an air conditioner. CONSTITUTION:Reciprocating rolling of vertical flaps 3,..., 3 are started by pressing a swing mode switch 42 of a remote controller 40. If a left limit value switch 43 is pressed when the flaps 3,..., 3 are fluctuated leftward, a left rolling limit angle VL is set at that time, and the flaps 3,..., 3 start rolling rightward. If a right limit value switch 44 is pressed during rightward rolling, the right rolling limit angle VR of the flaps 3,..., 3 is set. Thereafter, the flaps 3,..., 3 are rolled to be reciprocated rightward and leftward repeatedly between the angles VL and VR.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an air conditioner, and in particular to an air conditioner that can improve air conditioning comfort by reciprocating the direction of wind from a wind outlet. .

(Prior Art) Conventionally, in the field of air conditioners, there have been devices that swing the wind direction from the wind outlet in a reciprocating manner.
It is known from No. 4-41041 and Japanese Utility Model Application No. 1-58033. In these conventional examples, as shown in FIGS. 9 and 10, the air conditioner@A swings the wind direction back and forth with relatively large swing angles α in the left-right direction and β in the vertical direction with respect to the user B. It is made to move.

(Problem to be Solved by the Invention) However, in the conventional example described above, the wind direction is swung to an area where the blowing air does not hit the user B, for example, the range of α1 and β1, and unnecessary parts are air-conditioned. Therefore, there is room for improvement in terms of both air conditioning comfort and air conditioning efficiency for user B. Furthermore, depending on individual differences among users, some users may not like being directly hit by the blowing air, and in any case, the user can freely adjust the swing angle and swing range of the blowing air depending on the usage situation. A harmonizer is requested.

This invention was made to solve the above-mentioned conventional problems, and its purpose is to improve air conditioning comfort by allowing the user to freely change the swing angle and swing range of the blowing air. An object of the present invention is to provide an air conditioner that can improve air conditioning efficiency.

Repeat the rocking. At this time, the control section 6 receives the position signal 26 from the position detection means 20, the direction signal 27 from the swing direction detection means 21, and the limit position signals 28, 29 from the swing limit setting stages 23, 24. is input to the swing control means 22, and the swing control means 22 drives the drive source 10 in a predetermined drive direction until the swing limit angles VL and VR are reached. When a limit value command 33 is input from the outside to the swing limit changing means 25, the position of the wind direction changing body 3...3 in the swing direction at that time is set to a new swing limit angle VL, VR. Then, the swing limit positions VL and VR of the swing limit setting means 23 and 24 are changed. As a result, the swing limit position VL in both reciprocating directions,
VR can be freely set, and the reciprocating swing limit position and range of the wind direction changing body 3 can be freely changed depending on the usage condition of the air conditioner.
