Abstract

PROBLEM TO BE SOLVED: To surely close the discharge port by a blade at nonuse so as to prevent the penetration of foreign matter, by forming arm levers at the rears of a plurality of rotatable blades integrally, and linking the terminals of several levers by links, and enabling a link means to be driven by a drive means. SOLUTION: The tilt angle can be adjusted by rotating the blade 30 installed rotatably at the frame 10 of a discharge port 20, using a link lever 40, and the link lever 40 can shift up and down, according to the rotational direction of a drive motor 50 through a coupling lever 60. That is, at the blade 30, inclines inclined in the same direction are made at the top and bottom ends, and when the blade 30 rotates to close the discharge port 20, the ends of several blades 30 lie upon one another, whereby they can close the discharge port 20. Then, an arm lever 33 is made integrally at the rear of the blade 30, and the fellow terminals of the arm levers 33 are coupled with one another by a link lever to constitute a link mechanism.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooler / heater, and more particularly, when a cooler / heater is not used, a blade installed at the discharge port closes the discharge port to prevent foreign matter from entering. The present invention relates to a wind direction adjusting device for a cooling / heating device. Further, the present invention relates to a wind direction adjusting device capable of automatically operating a blade.

[0002]

2. Description of the Related Art Generally, a cooling / heating device such as an air conditioner or a hot air blower has a blade installed at its discharge port for adjusting the wind direction. Such a blade is provided with a protrusion at substantially the center of both side surfaces thereof, and is rotated about the protrusion. Each blade is connected to one link, and when the angle of one blade is adjusted, all the blades connected to the link interlock and rotate in the same direction.

Conventionally, there is a blade which is constructed so that the maximum rotation angle of the blade is maintained within 60 ° for adjusting the wind direction, and has only the function of simply adjusting the wind direction.
When the cooler / heater is not used for a long period of time, there is a disadvantage that the discharge port must be covered with a cover or the like in order to prevent dust or foreign matter from entering through the discharge port.

Further, since the wind direction angle of the blade is adjusted by the user directly grasping and operating the blade, it is troublesome and there is a risk that the blade may be damaged if force is applied. ..

[0005]

SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to enable the discharge port to be closed by rotating the blade when the cooling / heating device is not used. It is an object of the present invention to provide an improved wind direction adjusting device capable of automatically adjusting the wind direction adjusting function of the motor by driving a motor.

[0006]

In order to achieve the above object, according to the present invention, there is provided an air flow direction adjusting device provided at a discharge port of a cooling / heating device, which is at least rotatably installed about a horizontal axis. One or more blades, an arm lever integrally formed on the back surface of each blade, and a link mechanism that is rotatably connected to the end of each arm lever to form a link mechanism so that the blade closes the discharge port. A first position and a second position at which the blade opens the discharge port
There is provided a wind direction adjusting device characterized in that it includes a link means movable between positions and a drive means for driving the link means to the first and second positions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a wind direction adjusting device 100 according to the present invention.
FIG. The wind direction adjusting device 100 for a cooler / heater according to the present invention adjusts the inclination angle by rotating the blade 30 rotatably installed on the frame 10 of the discharge port using the link bar 40. Blade 3
The link bar 40 for adjusting the inclination angle of 0 is pivotally attached to the connecting lever 60, and the connecting lever 60 is attached to the rotary shaft 51 of the drive motor 50. With this configuration, the link bar 40 can move up and down according to the rotation direction of the drive motor 50.

As can be seen from the side cross section of the blade 30 shown in FIG. 2, the blade 30 has inclined surfaces 31 and 32 which are inclined in the same direction at the upper and lower ends thereof, so that the blade 30 rotates. When the outlet 20 is closed, the ends of the blades 30 overlap each other so that the outlet 20 can be closed more firmly. An arm lever 33 is integrally formed on the back surface of the blade 30 so that the blade 30 can rotate in a range of about 120 ° from a position where the discharge port 20 is closed to a position where the wind direction is determined downward (illustrated by a dotted line). ing.

As shown in FIG. 1, the blade 30 is connected to the link bar 40 through the end portion of the arm lever 33 to form a link mechanism. For this reason, a plurality of blade pivot parts 41 are provided on the link bar 40. At the lower end of the link bar 40, a connecting lever pivotal mounting portion 42 for linking with the connecting lever 60 is formed. Vertical blade 4 provided on the back surface of the link bar 40
Reference numeral 5 is for adjusting the direction of the air discharged through the discharge port to the left or right.

On the other hand, upper and lower limit switches 81 and 82 are installed around the upper and lower parts of the link bar 40. These limit switches prevent the link bar 40, which is moved up and down by the drive motor 50 to adjust the inclination angle of the blade 30, from being driven beyond the range of movement. That is, the link bar 40
Is moved downward by the drive motor 50 to move the blade 3
When 0 reaches the position where the discharge port 20 is completely closed, the lower limit contact point 44 of the link bar 40 actuates the lower limit switch 82 to cut off the power supply of the drive motor 50. The upper limit switch 81 is also arranged to be operated by the upper limit contact point 43 of the link bar 40 when the blade 30 rotates to the limit opening angle.

The drive motor 50 is capable of normal and reverse rotation,
It operates by receiving a signal from the operation panel 70 located on the front surface of the housing 5.

In the foregoing, specific embodiments of the present invention have been described. However, it will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the claims set forth herein.

[0014]

Therefore, according to the present invention, the rotation angle of the blade installed at the discharge port can be adjusted within a range of about 120 ° by using the drive motor and the link mechanism, and the cross-sectional shape of the blade is substantially parallel. Combined with the quadrilateral, when the cooler / heater is not used for a long period of time, the blade can close the discharge port to prevent foreign matter from entering.
