Abstract

PURPOSE:To enable an air direction-altering device to alter both the direction of the air sent and the range of space to which the air is sent by using an air direction-altering device which is composed of a first air-directing plate and a second air-directing plate, the first air-directing plate freely pivoted with the rotary shaft supported by a bearing at each of the two sides of the air outlet and the second air-directing plate freely pivoted with the rotary shaft supported by the axis of rotation of the first air-directing plate. CONSTITUTION:A second air-directing plate 16 is pivoted with its rotary shaft 15 supported internally by the rotary shaft 13 of a first air-directing plate 14 so that turning of the first air-directing plate 14 causes the second air-directing plate 16 to turn concomitantly and the direction of air is altered as desired. Turning of the second air-directing plate 16 relative to the first air-directing plate 14 alters the range of space to which the air is sent. By turning the second air-directing plate 16 relative to the first air-directing plate 14 in such a manner as to narrow the gap between the two air-directing plates 14, 16 at their ends for the ejection of air, the air can be sent to a narrower range of space, the velocity of air increased, and dry air sent farther and in a concentrated current. By turning the second air-directing plate 16 relative to the first air-directing plate 14 in such a manner as to widen the gap between them at their ends for the ejection of air, the air can be sent to a wider range of space and can dry a wider range.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of an exhaust port of an air conditioner.

[0002]

2. Description of the Related Art Conventionally, an air conditioner having a wind direction changing blade at its exhaust port has been known from Japanese Patent Laid-Open No. 2-37235. The wind direction changing blade described in this publication is configured by integrating two wind direction plates, and rotates around a rotation axis to change the air blowing direction. However, the blowing range could not be changed, and the usability was poor.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above drawbacks, and an object of the present invention is to provide an air conditioner capable of changing a wind direction and a blowing range.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a wind direction changing blade is rotatably supported by bearings formed on both sides of an exhaust port, and a rotary shaft is provided on a first wind direction plate. It is characterized by comprising a second wind direction plate rotatably supported on a rotary shaft.

[0005]

According to the above construction, the wind direction can be changed to a desired direction by rotating the wind direction changing blade. In addition, by adjusting the angle formed by the wind direction plates,
The blast can be diffused or concentrated depending on the usage condition.

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

Reference numeral 1 denotes a main body, the inner space of which is vertically divided by a water receiving tray 2, and a compressor (not shown) and a water receiver 3 are housed in the lower space of the main body.

Reference numeral 4 is a partition plate which divides the upper space of the main body 1 into front and rear parts, which is provided with an electric motor 5 to form a fan guide for a blower fan 6 attached to the electric motor 5, and is provided with a cooler 7 and a condenser in front thereof. A heat exchange chamber for accommodating the vessel 8 and a blower chamber for accommodating the blower fan 6 are formed in the rear.

Reference numeral 9 denotes an intake port formed on the front surface of the main body 1 corresponding to the heat exchange chamber. Between the intake port 9 and the cooler 7,
A filter 10 having a dust collecting function and a deodorizing function is detachably attached. Reference numeral 11 denotes an exhaust port formed on the rear portion of the upper surface of the main body 1, 12 is a wind direction changing blade attached to the exhaust port 11, and a ring-shaped rotary shaft 13 formed on both sides is rotatable around bearings on both sides of the exhaust port 11. First wind direction plate 14 pivoted on
And a second wind direction plate 16 in which a rotation shaft 15 is rotatably supported on the inner circumference of the rotation shaft 12 of the first wind direction plate 14. Reference numeral 17 denotes a plurality of flow straightening vanes formed on the second wind direction plate 16, the first wind direction plate
14 is extended to a position close to or in contact with 14, and rectifies the air flow passing between the first airflow direction plate 14 and the second airflow direction plate 16 and deforms the first airflow direction plate 14 and the second air direction plate 16. This is prevented and the space between the first wind direction plate 14 and the second wind direction plate 16 is maintained.

When the compressor and the electric motor 5 are driven, the air taken in through the intake port 9 is cooled by the cooler 7 and the condenser 8.
Is dehumidified and becomes dry air and is blown from the exhaust port 11. The air flow from the exhaust port 11 has its air flow direction and air flow range changed by the air flow direction changing blade 12. That is, when the first wind direction plate 14 is rotated, the second wind direction plate 16 pivots the rotation shaft 15 of the first wind direction plate 14 on the inner circumference of the rotation shaft 13 of the first wind direction plate 14, so that the first wind direction plate 14 is rotated. By doing so, the second wind direction plate 16 is integrally rotated as in the conventional case, and the wind direction is changed to a desired direction (see FIG. 3). Further, by rotating the second airflow direction plate 16 with respect to the first airflow direction plate 14, the blowing range is changed. As shown in FIG. 4, a state in which the second wind direction plate 16 is rotated with respect to the first wind direction plate 14 and adjusted so that the distance between the blow-out side end portions of the first wind direction plate 14 and the second wind direction plate 16 is narrowed. In this case, the blowing range is narrowed, the wind speed is increased, and the dry wind can be blown intensively to a distant place. Therefore, it is suitable, for example, when intensively drying a closet, a shoe box, or a small amount of laundry. Further, as shown in FIG. 5, the second wind direction plate 16 is rotated with respect to the first wind direction plate 14 to move the first wind direction plate 16 to the first wind direction plate 14.
In the state where the distance between the air blow side plate 14 and the second air flow direction plate 16 is adjusted to be wide, the air blowing range is wide and a wide range can be dried. Therefore, for example, a lot of laundry is dried. Suitable in some cases.

[0011]

As described above, according to the present invention, it is possible to adjust the air blowing direction and the air blowing range according to the use condition with a simple structure, and it is possible to improve the convenience of use. ..
