Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner and an air conditioner, and is particularly suitable for an air conditioner having a control device for holding a wind direction at a predetermined position.

[0002]

2. Description of the Related Art In conventional air conditioners, the
As described in JP-A-75753, the wind direction is changed in conjunction with the operation of the solenoid. However, this method requires a plurality of solenoids to switch the wind direction in several steps, which is expensive. In addition, when switching the wind direction, there is a problem that it cannot be switched without looking at the direction of the outlet grill.

[0004]

In the above-mentioned prior art, since the stop position is operated while looking at the direction of the blowout grill, the position of the blowout grill will be affected if the remote controller is installed far away from the air conditioner. It is difficult to adjust. In addition, it is difficult to adjust the position of an air conditioner with a structure in which the outlet grill cannot be seen, and in an air conditioning system in which multiple air conditioners are connected to one remote controller, it is necessary to make all air conditioners have the same wind direction. There was a problem such as being unable to do so.

An object of the present invention is to provide an air conditioner that solves the above problems.

[0006]

In order to achieve the above object, the present invention is an air conditioner provided with an air flow direction drive mechanism provided in an indoor unit and a remote control, wherein the remote control is an air flow direction adjusting switch. A plurality of display portions are provided, and when the wind direction adjustment switch is pressed, the plurality of display portions indicate that the wind direction automatic operation mode has been entered, and the indoor unit operates the wind direction drive mechanism.

Further, in the above-mentioned configuration, it is desirable that the plurality of display portions are displayed in order and then in reverse order.

Further, in the above, it is desirable that the plurality of display portions repeat a stepwise changing operation.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a block structure diagram of an air conditioner, in which a remote control 1 is an air direction adjusting switch 1.
a, a wind direction display 1b, and a transmission circuit 1c. The indoor unit 2 includes a wind direction drive mechanism 2a, a wind direction mechanism 2b, a wind direction position detection mechanism 2c, and a calculation unit 2e. Figure 2 shows the wind direction mechanism 2b
3 is a detailed view of the wind direction position detection mechanism 2c, in which the wind direction detection mechanism 2c detects when the wind direction is horizontal. FIG. 3 is a detailed view of the wind direction mechanism 2b and the wind direction drive mechanism 2a, which are connected by connecting bars 3 and 4. The rotational driving of the wind direction drive mechanism 2a is performed by the connecting bars 3 and 4 by the wind direction mechanism 2a.
b is converted to swing drive from horizontal to 80 ° downward. FIG. 4 shows a method for displaying the wind direction when the wind direction adjusting switch 1a is pressed. The wind direction is displayed by turning on the fan-shaped 5 to 8 wind direction display portions shown in FIG. 8 from horizontal
The display up to 0 ° is made to correspond to A to G in the figure, and when the wind direction adjustment switch 1a is pressed, the wind direction display is displayed from A to G in FIG. 4 and then gradually changed from G to A in order.
After that, this operation is repeated. The display indicates that the wind direction automatic operation mode has been entered. At this time, the wind direction automatic operation data is transmitted from the remote controller 1 to the indoor unit 2 via the transmission circuit 1c.
Send to. The indoor unit 2 operates the wind direction drive mechanism 2a based on the wind direction automatic operation data sent from the remote controller 1, and reciprocates the wind direction mechanism 2b from the horizontal position to 80 ° downward.
The wind direction position detection mechanism 2c sends a horizontal signal to the calculation unit 2e when the wind direction mechanism 2b becomes horizontal, and the calculation unit 2e counts the time from the reception of a horizontal signal until the reception of the next horizontal signal, Calculate the time required for one cycle of the mechanism.
When the wind direction mechanism is not moved automatically, the initial data set in advance is set as one cycle time.

In order to maintain the wind direction in a certain direction, when the wind direction display 1b of the remote controller 1 is in the wind direction display position to be held among the positions A to G in FIG. 4, the wind direction adjusting switch 1a is pressed to stop the display. . When the wind direction adjustment switch 1a is pressed, the wind direction display data at this time is sent to the indoor unit 2 via the transmission circuit 1c. The calculation unit 2e calculates the drive time from the wind direction position data and the time required by the wind direction mechanism for one cycle, and moves the wind direction drive mechanism 2a for a predetermined time to move the wind direction mechanism 2
Hold b in a predetermined wind direction. The wind direction position data can be set in a plurality of stages corresponding to the displays A to G of the wind direction display 1b.

Further, in this method, since the wind direction display portions 5 to 8 displayed on the remote controller 1 and the wind direction mechanism 2b of the indoor unit 2 do not always need to be synchronously operated, as shown in FIG.
Even when the remote controller 1 has a system configuration in which a plurality of indoor units are connected, if the wind direction is set by the remote controller 1, even if the wind direction mechanism of the connected indoor units is not synchronized, the same wind direction is obtained. Easy to do.

Since the computing unit 2e counts one cycle time of the wind direction mechanism 2b, the one cycle time of the wind direction mechanism in the normal case is preset and compared with the time required for one actual cycle. An abnormality in the wind direction drive mechanism 2a or the wind direction position detection mechanism 2c can be detected.

[0013]

According to the present invention, it is possible to obtain an air conditioner in which the position of the blowout grill can be easily adjusted even if the remote controller and the air conditioner are installed at different positions.
