Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner and an air conditioner, and more particularly to an air conditioner having a control device for maintaining a wind direction at a predetermined position. 2. Description of the Related Art A conventional air conditioner is disclosed in
As described in -75753, the wind direction is changed in conjunction with the operation of the solenoid. However, this method requires a plurality of solenoids when switching the wind direction in several steps, which is expensive. In addition, when the wind direction is switched, there is a problem that the wind direction cannot be switched unless the direction of the blowout grill is checked. [0003] In the above prior art, the stop position is operated while observing the direction of the air outlet grille. Therefore, if the installation location of the remote controller is far from the installation position of the air conditioner, the air outlet is blown out. Difficulty adjusting the position of the grill. In addition, it is difficult to adjust the position of an air conditioner with a structure in which the blowout grill is not visible, and in an air conditioning system that connects multiple air conditioners to one remote control, it is necessary to make the air direction of all air conditioners the same. There were problems such as inability to do so. An object of the present invention is to provide an air conditioner which solves the above-mentioned problems. [0005] In order to achieve the above object, the present invention relates to an air conditioner provided with a wind direction mechanism and a remote controller for displaying a wind direction. And a plurality of display portions, wherein the display portion
It can be displayed in one direction and then in the other direction.
And any of the display portions can be changed by the wind direction adjustment switch.
It is turned on to determine the wind direction in relation to this display portion . Further, in the above, it is desirable that the plurality of display portions be four and the wind direction is displayed in seven stages. An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a block diagram of an air conditioner.
a, wind direction display 1b, and 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
FIG. 3 is a detailed view of the wind direction position detection mechanism 2c. 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 rotation of the wind direction drive mechanism 2a is controlled by the connecting bars 3 and 4 to the wind direction mechanism 2a.
b is converted into a swing drive from horizontal to 80 ° downward. FIG. 4 shows a wind direction display method when the wind direction adjustment switch 1a is pressed. The wind direction is displayed by turning on the fan-shaped wind direction display portions 5 to 8 shown in FIG. 8 from horizontal
The display up to 0 ° corresponds to A to G in the figure, and when the wind direction adjustment switch 1a is pressed, the wind direction display changes from A to G in FIG. 4 and then changes stepwise from G to A.
Thereafter, this operation is repeated. The display indicates that the wind direction automatic operation mode has been set. At this time, the wind direction automatic operation data is transmitted from the remote controller 1 via the transmission circuit 1c to the indoor unit 2
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.
When the wind direction mechanism 2b becomes horizontal, the wind direction position detection mechanism 2c sends a horizontal signal to the calculation unit 2e, and the calculation unit 2e counts the time from the reception of the horizontal signal to the reception of the next horizontal signal. Calculate the time required for one cycle of the mechanism.
When the wind direction mechanism is not automatically moved, the initial data set in advance is set as one cycle time. In order to maintain the wind direction in a certain direction, the wind direction adjustment switch 1a is pressed when the wind direction display 1b of the remote controller 1 reaches the desired wind direction display position among A to G in FIG. 4 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 a driving time from the wind direction position data and the time required for one cycle of the wind direction mechanism, and moves the wind direction driving mechanism 2a for a predetermined time to set the driving time.
b is maintained at a predetermined wind direction. The wind direction position data can be set in a plurality of stages corresponding to the indications A to G of the wind direction display 1b. 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 a system configuration in which a plurality of indoor units are connected to the remote controller 1 is used, if the wind direction is set with the remote controller 1, even if the wind direction mechanisms of the connected indoor units are not synchronized, the same wind direction is used. Can be easily done. Since the calculating section 2e counts one cycle time of the wind direction mechanism 2b, it calculates one cycle time of the wind direction mechanism in a normal case and compares it with the time required for one actual cycle. An abnormality of the wind direction drive mechanism 2a or the wind direction position detection mechanism 2c can be detected. 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 installation location of the remote controller is far from the installation position of the air conditioner.
