Abstract

PURPOSE:To shorten the time interval to raise the room temperature in the living space upon starting up a cooling or heating operation and realize an even distribution of room temperature by setting a limited sweep range for cooling operation and another limited sweep range for heating operation within the overall sweeping range, and oscillating the horizontal air blowout louver in the cooling sweep range for a cooling operation and in the heating sweep range for a heating operation. CONSTITUTION:When the Normal/Limited selection switch 27 is switched to 'Limited' with the Cooling/Heating selection switch 24 switched to 'Cooling', the same number of plus and minus pulses are alternately generated which is necessary to oscillate the horizontal air blowout louver 6 within the cooling sweep range of 0 deg.C to 30 deg.C. Then, the louver 6 automatically oscillates in the range of 0 deg.C to 30 deg.C, and the cold air blown out of the air outlet 5 descends to be most effectively supplied to the living space 12. When the switch 27 is switched to 'Limited' with the switch 24 switched to 'Heating', the louver 6 automatically oscillates in the range of 40 deg.C to 80 deg.C, and the hot air blown out of the air outlet 5 rises.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method of controlling a blowout louver of an air conditioner.

(Prior Art) A longitudinal sectional view of a conventional wall-mounted indoor unit of a separate type air conditioner is shown in FIG.

In Fig. 3, 1 is the main body, 2 is a suction grill provided on the front upper part of the main body 1, 3 is a heat exchanger, 4 is a cross-flow type fan disposed at the rear of the lower part of the heat exchanger 3, and 5 is a An air outlet is provided at the lower front of the main body 1, 6 is a horizontal air outlet lever provided at the air outlet 5, 7 is a drain pan provided under the heat exchanger 3, and 8 is provided behind the suction grill 2. Air filter installed.

This wall-mounted indoor unit 9 is installed at a predetermined height on the wall surface 11 of the room 10, as shown in FIG.

When the air conditioner is in operation, the fan 4 rotates, and refrigerant from an outdoor unit (not shown) circulates through the heat exchanger 3.

In this way, indoor air is drawn into the main body 1 through the suction grille 2, as shown by the solid arrow, and the dust contained therein is removed by passing through the air filter 8, and the heat exchanger 3 is It is cooled or heated by exchanging heat with the refrigerant in the process of flowing, and is energized by the fan 4,
Thereafter, the air is guided from the air outlet 5 to the horizontal air outlet louver 6 and blown into the room.

This horizontal blow-off louver 6 is driven by a motor (not shown) to swing around a horizontal axis to a horizontal position (06).
It reciprocates within a swing range of approximately 90@ from vertically downward (90').

(Problems to be Solved by the Invention) In the conventional air conditioner described above, regardless of whether the air conditioner is in cooling operation or heating operation, the horizontal blowing lever 6 is horizontal (0
It swings back and forth within a swing range of approximately 90' from vertically downward (90') to vertically downward (90').The cold air blown out from the outlet 5 during cooling operation is low in temperature and heavy, so it descends, and during heating operation At times, the hot air blown out from the air outlet 5 rises because its temperature is high and light. Therefore, all of the cold air and hot air blown out from the air outlet 5 reach the room 10.
Since the air is not blown into the living space 12 (predetermined in advance for evaluating temperature distribution, etc.), there are problems such as poor room temperature distribution and slow rise in room temperature at the start of operation.

(Means for Solving the Problems) The present invention was invented to solve the above problems, and the gist thereof is to provide a horizontal blowout louver at the blowout outlet that swings back and forth within a predetermined swing range. In the air conditioner, a specific cooling swing range and a heating swing range are set within the swing range, and during cooling operation, the specific cooling swing range is set, and during heating operation, the specific heating swing range is set. The present invention provides a method for controlling a blowout louver of an air conditioner, characterized in that the horizontal blowout louver is reciprocated within a swing range.

(Function) Since the present invention has the above configuration, the horizontal blowout louver swings back and forth within a specific cooling swing range during cooling operation, and swings back and forth within a specific heating swing range during heating operation. Therefore, both cold air and warm air are efficiently blown into the living space.

(Example) One embodiment of the invention is shown in FIG.

FIG. 1 shows a control block diagram of the horizontal blow-off louver 6, in which 21 is a remote control device, 22 is a control device incorporating a microcomputer, and 23 is a pulse motor for swinging the horizontal blow-off louver 6 back and forth.

Cooling/warming switch 24 provided on the remote control device 21
The outputs of the fixed/swing changeover switch 25, the fixed angle setter 26, and the normal/specific changeover switch 27 are input to the pulse generation means 28 of the control device 22, where the outputs are inputted to the pulse generation means 28 of the control device 22, and the outputs are inputted to the pulse generation means 28 of the control device 22. A pulse is generated and this pulse is supplied to the pulse smoke 23 via the output means 30.

Thus, the pulse generating means 28 generates pulses as follows based on the commands from the storage means 28 in response to the signals input thereto.

When the fixed/swing changeover switch 25 is switched to the fixed side, that is, to the side where the horizontal blow-off louver 6 is fixed, no pulses are generated thereafter. Therefore, the horizontal blow-off louver 6 stops at the angle when the switch 256 is switched.

When the angle at which the horizontal blow-off louver 6 should be fixed is set by the fixed angle setter 26, the number of pulses necessary to swing the horizontal blow-off louver 6 from the angle at the time of setting the angle to the angle at which it should be fixed is emitted. generated and no longer generates pulses. Therefore, the horizontal blowing lever 6 is fixed at a set angle.

The fixed/swing changeover switch 25 is switched to the swing side,
In addition, when the normal/specific selector switch 27 is switched to the normal side, it is necessary to reciprocate the water blowing louver 6 within the range from horizontal (0'') to vertically downward (90°). The same number of positive or negative pulses are generated alternately. Therefore, the horizontal blowout louver 6 moves from horizontal (0°) to vertically downward (9°).
6 or more, which reciprocate within the range of 0'), is the same regardless of which way the cooling/warming changeover switch 24 is switched.

When the normal/specific selector switch 27 is switched to the specific side with the cold/warm selector switch 24 switched to the cooling side, the horizontal blowout louver 6 is moved to a specific cooling swing range.
That is, the same number of positive or negative pulses necessary for reciprocating swing within the range from 0'' to 30 degrees are generated alternately.

When the normal/specific selector switch 27 is switched to the specific side while the cold/warm selector switch 24 is switched to the heating side, the water outlet louver 6 is moved to a specific heating swing range.
That is, the same number of positive or negative pulses necessary to make two (reciprocating) movements within the range from 40@ to 80'' are alternately generated.

The rest of the structure is the same as the conventional one shown in FIGS. 2 and 3, and corresponding members are given the same reference numerals and their explanations will be omitted.

Therefore, if the fixed/swinging switch 25 is switched to the swinging side and the normal/specific changeover switch 27 is switched to the specific side, the horizontal blowout louver 6 will automatically move from O' to 30° during cooling operation. Oscillates back and forth within a range of °. Then, the cold air blown out from the air outlet 5 is low in temperature and heavy, so it descends, and the cold air is most effectively blown into the living space 12 as shown by the broken line in FIG.

On the other hand, during heating operation, the horizontal blowout louvers 6 are automatically
It swings back and forth within the range of 0" to 80 degrees. Then, the warm air blown out from the air outlet 5 rises because its temperature is high and it is light, and the warm air most effectively blows into the living space 1 as shown by the chain line.
blown into 2.

Therefore, if the normal/specific selector switch 27 is switched to the specific side at the start of cooling and heating operation, the living space 1
The room temperature inside the room rises quickly, and the room temperature distribution improves quickly.

Note that the swing range for cooling and the swing range for heating may be appropriately selected depending on the relative position of the air outlet 5 and the living space 12.

Further, the normal/specific selector switch 27 may be switched to the specific side not only at the start of operation but also during steady operation.

(Effect of the invention) In the present invention, a specific cooling swing range and a heating swing range are set in the swing range, and during cooling operation, the specific cooling swing range is set, and during heating operation, the specific heating swing range is set. Since the horizontal blow-off louvers are reciprocated within the living space, the rise time of the room temperature in the living space at the start of cooling or heating operation can be shortened, and the room temperature distribution can be made more uniform.
