Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to an air conditioner that performs cooling or heating, and particularly relates to a control configuration for a louver provided at an air outlet.

<Prior art> Generally, in an air conditioner, a desired indoor temperature is set in advance, and a compressor and blower are operated according to the output of a room temperature sensor installed indoors to maintain the indoor air temperature at this set temperature. Juan's
ON and OFF are performed.

In addition, on the other hand, the conditioned room air is discharged from the outlet in response to the output of the room temperature sensor, and this outlet is provided with a louver that controls the direction of the blowing air. Some types use a motor to swing the louvers in order to diffuse the blown air throughout the room.

Due to the diffusion of the louvers, the air conditioned air is evenly distributed throughout the room, and this diffusion is effective, especially until the indoor air reaches the set temperature.However, in conventional air conditioners of this type, the set temperature Even when the set temperature is reached, the louver continues to be driven and is not automatically released unless the user operates it manually, and the driving of the louver after the set temperature is reached is, so to speak, wasted.

Therefore, in Utility Model Application Publication No. 57-100140, in an air conditioner that stops the compressor when a predetermined temperature is reached, the louver of the outlet is oscillated until the predetermined temperature is reached and the compressor is stopped. An air conditioner has been proposed in which the swinging of the louvers is stopped at the same time as the temperature is reached and the compressor is stopped.

However, this conventional air conditioner controls the start and stop of the louvers' swinging based on simply reaching a predetermined temperature, so especially when heating, the set temperature is reached first from the start of operation, and then the temperature rises. When the temperature drops below the set temperature again, the louvers will be shaken again. However, if the louver is turned on immediately after the temperature drops to the set temperature, the blown air will be agitated, causing the user to feel chilly even though the temperature is at the set temperature.

In addition, since the swing of the louver is simply controlled in conjunction with the drive of the compressor, if this louver control is used for an air conditioner that operates at low speed without stopping the compressor when the set temperature is reached, the set temperature There was a possibility that the louver could be driven even after reaching the point.

<Purpose> The present invention has been made in view of the above points, and aims to provide an air conditioner that can effectively stir the blown air into a room without making the user feel chilly.

<Example> Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram of the device used in the embodiment of the present invention.
FIG. 2 is a partially enlarged sectional view of FIG. 1.

In this Figure 1, 1 is the air conditioner body, 2 is
This is a remote control for controlling an air conditioner main body 1, and the air conditioner main body 1 has an air outlet 3 at the lower part of the front side.
A receiving section 4 is provided which forms a remote controller 2 and receives a wireless signal from the remote controller 2. On the other hand, the remote control 2 is an operation section (not shown) for performing various operations.
A room temperature sensor 5 that detects the indoor temperature and a transmitter 6 that transmits a signal from the remote controller 2 are also provided.

As shown in FIG. 2, which is a cross-sectional view of the outlet 2 portion of FIG. The louvers 7 are connected by interlocking means (not shown) such as rods so as to swing at an angle α, and this interlocking means includes a motor (not shown) for driving the louvers 7. It is connected.

Next, the control circuit block of the embodiment of the present invention will be explained using FIG.

In FIG. 3, 3 is a receiving section of the air conditioner body 1, and 4 is a remote control.

8 is a microcomputer that receives the signal from the receiver 3 and generates a control signal. This microcomputer 8 determines whether the indoor temperature reaches the set temperature, and as a result of this determination, uses this set temperature as a reference and issues a command to drive the louver 7 until the reference is reached. It sometimes issues a command to stop the louver 7.

In this case, especially in heating operation, after the indoor temperature reaches the set temperature for the first time after starting the operation, do not immediately swing the louver 7 to stir the indoor air even if the indoor temperature falls below the set temperature again. This way, you won't feel chilly and it will be more comfortable to use. Therefore, after the microcomputer 8 reaches the set temperature for the first time after starting the operation, the microcomputer 8 corrects the above reference so that the set temperature becomes looser, and thereafter controls the louver 7 around this corrected reference. It emits a signal to control starting and stopping. For example, if the set temperature is set to 20°C during heating, the louver 7 will be oscillated until the set temperature of 20°C is reached after the start of operation, and the louver 7 will be stopped when it reaches 20°C. control to do so. Thereafter, for example, the criterion for driving the louvers 7 is corrected to 18 degrees Celsius, which is the direction in which the set temperature is relaxed, and a signal for driving the louvers 7 is generated only when the indoor air falls below 18 degrees Celsius. Conversely, if the temperature is set at 20°C during cooling, the louvers 7 will be turned on and off based on, for example, 22°C after the set temperature is reached for the first time.

Reference numeral 9 denotes a control circuit that receives the above-mentioned command from the microcomputer 8 and controls the operation of the motor 10 for driving the louver 7.

To explain the operation of the air conditioner with the above configuration, first, during heating, since the indoor air temperature is low at the beginning of operation, conditioned air is blown out from the outlet 2 having the louver 7 in order to bring the room temperature closer to the set temperature. At the same time, the louver 7 performs a swinging motion by the function of the microcomputer 8, and hot air is evenly blown into the room. After a while, when the room temperature sensor 5 informs the microcomputer 8 that the room temperature has reached the set temperature, the microcomputer 8 instructs the control circuit 9 to stop the louver 7, and the louver 7 stops.

When the set temperature is reached for the first time after starting the operation in this manner, the standard for driving the louver 7 is corrected in the direction of loosening the set temperature, which is the original criterion for driving the louver 7. For example, if the temperature is set at 20°C during heating as shown above, then the temperature will be set at 18°C.
is the standard for starting and stopping 7 louvers.

Therefore, the louver 7 will be driven again only when the indoor air temperature falls below 20°C and further below the relaxed standard of 18°C after reaching the set temperature for the first time. (The air conditioner is controlled to maintain the indoor air temperature close to the set temperature of 20°C.) In this way, the criterion for driving the louver 7 is corrected after the set temperature is first reached. Then,
The usability is particularly excellent during heating. That is, if the louver 7 is driven immediately when the indoor air temperature decreases and reaches the set temperature again after reaching the set temperature for the first time, the indoor air temperature will be lower at the time when the louver 7 is driven again. Even though the temperature is at the set temperature or almost the same, the user may feel chilly due to the stirring of the blown air due to the swinging of the louver 7. Therefore, when the louver 7, which had been swinging, reaches the set temperature for the first time after starting the operation, it stops, and then the indoor air temperature continues to increase instead of driving the louver 7 immediately after reaching the set temperature. The louver 7 is driven only after the temperature has been lowered. In this way, the louver 7 will stir the air after the indoor temperature has fallen relatively below the set temperature and it becomes necessary to rapidly heat the entire room, so that when the indoor air temperature is set, there will be no stirring and the chilly temperature will be reduced. I don't feel it.

<Effects> According to the present invention, the louver is oscillated to stir the blowing air until the set temperature reaches the standard, and the louver is stopped when the standard is reached, so there is no waste. The blowing air can be stirred.

In the case of the present invention, the above standard is corrected so that the set temperature is loosened after the set temperature is reached for the first time after the start of operation, and the start and stop of the louver swing is controlled based on this corrected standard. Therefore, it is possible to prevent the user from feeling chilly due to the operation of the louver when the temperature is set, and it is possible to improve the feeling of using the air conditioner.
