DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling an air flow of an air conditioner.

[0002]

2. Description of the Related Art FIG. 2 is a longitudinal sectional view of a wall-mounted indoor unit of a conventional separation type air conditioner. In FIG. 2, 1 is a main body casing, 2 is a front panel mounted on the front surface of the main body casing 1, and 3 is a plate fin tube type heat exchange arranged to face a suction grill 2a formed on the front panel 2. Vessel, 4 is heat exchanger 3
The cross-flow type fan arranged at the rear of the lower part of the front panel 5 is an air outlet formed at the lower part of the front panel 2, 6a, 6b
Is a horizontal louver disposed at the air outlet 5 and extending horizontally; 15 is a vertical louver disposed at the air outlet 5 and extends vertically; 7 is a drain pan disposed below the heat exchanger 3; Is an air filter disposed on the back of the suction grill 2a.

The horizontal blowout louvers 6a and 6b are connected to each other by a stay 9 so as to be spaced apart and parallel to each other, and are integrally formed around the shaft 10 by rotating a shaft 10 fixed to the stay 9 by a motor (not shown). And rotate.

The vertical louver 15 is provided with pins at right and left intervals.
The vertical louvers 15 are rotatably supported by the main body casing 1 through the projections 11 and project from the lower surface of the rear end thereof.
By moving the slider 13 with which the engagement 12 moves in the left-right direction, the slider 13 rotates around the pin 11 while maintaining a parallel state with each other.

During operation of the air conditioner, the fan 4 rotates,
Refrigerant from an outdoor unit (not shown) circulates through the heat exchanger 3. Then, as indicated by the solid arrow,
When the air is sucked into the main casing 1 from the suction grill 2a and flows through the air filter 8, dust contained therein is removed, and then heat exchanges with the refrigerant in the process of flowing through the heat exchanger 3 for cooling or cooling. After being heated and then sucked into the fan 4 and energized, the air is blown into the room from the air outlet 5 with the blowing direction regulated by the vertical louvers 15 and the horizontal blowing louvers 6a and 6b.

[0006]

In the above-mentioned conventional air conditioner, the two horizontal blowout louvers 6a and 6b rotate around the horizontal shaft 10 integrally, so that the blowout direction of the blown air is changed. Although it could be changed up and down, the wind speed could not be adjusted, and no fluctuation could be given to the blowing wind.

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and its gist is to provide a single unit opening at the lower front part of a wall-mounted indoor unit.
In the air conditioner in which a plurality of horizontal blowout louvers are horizontally arranged at predetermined intervals above and below the air blowout outlet, and the horizontal blowout louvers are each driven by a separate motor, at least an upper portion of the horizontal blowout louvers is provided. any fixed to the angular position, the wind direction of the air blown by periodically reciprocating swinging other at least one lower within a predetermined angular range in the state suitable for cooling operation or heating operation of the single , Wind speed and arrival
Reach distance periodically changing the in outlet air control method of an air conditioner according to claim Rukoto.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. The horizontal blowout louver 20 is fixed to a shaft 22 through an arm 21, and the horizontal blowout louver 23 is fixed to a shaft 25 through an arm 24. The shafts 22 and 25 are arranged in the air outlet 5 so as to be parallel to each other at predetermined intervals vertically, and both ends thereof are rotatably supported by the front panel 2.

The shaft 22 is rotatably driven by a motor 26 connected to one end thereof, and the shaft 25 is rotatably driven by a motor 27 connected to the other end thereof.

The upper horizontal blow louver 20 is fixed so that the blow air is directed substantially horizontally during the cooling operation, and is fixed such that the blow air is directed downward during the heating operation. However, the lower horizontal blow louver 23 is operated in the cooling operation. During the heating operation and during the heating operation, the air conditioner is periodically reciprocated within a predetermined angle range, so that fluctuations can be given to the blown air. FIG.
In, 28 is a stabilizer. The other configuration is the same as that of the conventional one shown in FIG. 2, and corresponding members are denoted by the same reference numerals.

Thus, the upper horizontal blow louver 20 is individually driven by the motor 26 and the lower horizontal blow louver 23 is individually driven by the motor 27 to rotate independently. During the cooling operation, the upper horizontal blow louver 20 is rotated. Angle position suitable for cooling,
That is, the horizontal blowout louver 23 below is fixed substantially horizontally as indicated by the solid line, but periodically swings reciprocally within a predetermined angle range. Thus, the wind speed and direction of the cool air blown out from the air outlet 5 and the reach thereof can be periodically changed to give a so-called fluctuation, thereby reducing the draft feeling for the occupants and providing a refreshing feeling. Can be given.

During the heating operation, the upper horizontal blowout louver 20 is fixed at an angular position suitable for heating, that is, downwardly as shown by a dashed line in FIG. The wind speed and direction of the warm air blown out from the air outlet 5 by periodically reciprocating swinging within the range.
In addition, it is possible to give a so-called fluctuation to the warm air by periodically changing the reaching distance, thereby making the warm air spread over a wide area and uniforming the temperature distribution in the room, thereby improving the air conditioning feeling. Can be.

Although the above embodiment has two horizontal blowout louvers, it is a matter of course that the present invention can be applied to those having three or more horizontal blowout louvers.

[0014]

In the present invention, and fixed at an arbitrary angular position suitable for one of at least the upper portion of the plurality of water Izuru Hirabuki louver to the cooling operation or heating operation, a predetermined one sheet of another of the at least lower in this state period wind direction of the outlet air, the wind speed and reach by periodically reciprocating swinging within the angular range
To order varied, homogenization to occupants of the conditioned Fuiringu during heating operation by Watarura go warm air a wide range of temperature distribution in the room it is possible to provide a cooling sensation to the person in the room at the time of cooling operation Can improve.
