Description

Diffuser fastening structure of air conditioner

The present invention relates to a diffuser of an air conditioner, and in particular, a separate variable discharger is fastened so as to be openable and closed on both side walls of the diffuser for blowing heat exchanged air to the outside, thereby increasing the discharge area of the blown air and at the same time Diffuser fastening structure of the air conditioner to reduce the noise generated.

As shown in FIG. 1, the diffuser fastening structure of a conventional air conditioner includes a body casing 1 and rotatably fastened at a predetermined angle to an upper front surface of the body casing 1 to exchange heat exchanged air in an up and down direction. A plurality of horizontal louvers (2) for guiding and discharging with each other, and the rear of the horizontal louvers (2) are rotatably fastened by a predetermined angle and integrally diverted by a drive motor to exchange heat in front of the body casing (1). It consists of a plurality of vertical louvers (3) for guiding and discharging the air.

As shown in FIGS. 1 and 2, the diffuser coupling structure of the conventional air conditioner includes a body casing 1 through a plurality of horizontal louvers 2 in which heat-exchanged air is fastened to an upper front surface of the body casing 1. Discharged to the front of the horizontal louvers (2) in the up and down direction, the discharge direction was determined, and the vertical louvers (3) fastened to the rear of the horizontal louvers (2) are left when the drive motor is operated. Rotate with the discharge direction switched in the right direction.

However, such a diffuser fastening structure of the conventional air conditioner, since the blowout direction of the heat exchanged air is limited only to the front of the body casing, the wind speed distribution of the blown air is limited only to the front of the body casing, to compensate for this Although the ejection range was enlarged by switching the discharge direction to the left and right direction to some extent through the vertical louvers interlocked by the drive motor, the temperature distribution in the room is still uneven because the angle of ejection is very limited. In addition, discharge noise was generated because the discharge air was concentrated only on the front surface of the body casing.

The present invention is to solve the above-described drawbacks, by adding a variable discharger for discharging the heat-exchanged air not only on the front surface of the body casing but also on both side walls, to increase the discharge area of the blown air to evenly distribute the temperature of the indoor air In addition, to provide a diffuser fastening structure of the air conditioner to reduce the generated noise of the blown air at the same time.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 3 to 5, the diffuser fastening structure of the air conditioner of the present invention is rotatably fastened by a predetermined angle to the body casing 10 and the upper front surface of the body casing 10 to exchange heat exchanged air. A plurality of horizontal louvers 20 for guiding and discharging up and down, and installed on the rear side of the horizontal louvers 20 and hinged to both rear wall surfaces of the body casing 10 in the opposite direction by the drive motor Simultaneously interlocked in the horizontal direction is characterized in that it consists of a variable discharge machine 30 for guiding and discharging the air heat exchanged and opened at a time by a predetermined angle.

The variable ejector 30 is composed of two ejector casings 31, a plurality of vertical louvers 32, two racks 33, a pinion 34, a driving motor 35, and a body casing. A plurality of vertical louvers 32 are rotatably fastened to the front of each of the ejector casings 31 which are integrally opened and closed at left and right sides thereof, respectively, and an air passage is formed therein, and the two ejector casings 31 are formed. The racks 33 are attached to the lower surfaces of the racks, respectively, and the racks 33 are engaged with both sides of the pinion 34 fastened to the driving motor 35 to be rotated forward and reverse, so as to move horizontally in the opposite direction. .

The diffuser fastening structure of the air conditioner of the present invention, as shown in Figures 3 to 6, the body casing (10) through a plurality of horizontal louvers 20, the heat exchanged air is fastened to the upper front of the body casing (10) ) Is discharged to the front, and the user operates the horizontal louvers 20 in the up and down direction to determine the ejection direction of the discharge air, if necessary is installed on the rear side of the horizontal louvers (2) and the body casing (10) The pinion 34 is rotated forward and reverse by operating the drive motor 35 of the variable discharger 30 which is hinged to both rear wall surfaces of the pinion 34, and is engaged to both sides by forward and reverse rotation of the pinion 34. The racks 33 are horizontally transferred in opposite directions to each other in the direction of the arrow, and the ejector casings 31 are interlocked with each other by the movement of the racks 33 at the same time in opposite directions on both side walls of the body casing 10. Opening and closing, thereby exchanging heat Is simultaneously discharged from both side walls of the body casing 10 so that the overall discharge area is increased, the blown air is distributed evenly in the room, and the temperature distribution of the indoor air is evenly distributed, and the constant discharge air volume is distributed to the wide discharge area. Noise generated at the outlet is also reduced.

Diffuser fastening structure of the air conditioner of the present invention, by adding a variable discharger for discharging the heat-exchanged air at the same time as well as the front surface of the body casing, the discharge area of the blowing air is increased, the room temperature is even, The noise generated by the air is also reduced.
