Air conditioner installed on the ceiling-side wall or ceiling (indoor-side unit of a separate type air conditioner composed of indoor-side units and outdoor-side units) and wall-mounted air that can be attached to the wall Various types of air conditioners such as a conditioner or an embedded air conditioner embedded in a ceiling can be used.

The air conditioner 1 is only required to be able to supply conditioned air (heated, cooled, dehumidified, humidified air) into a room, and is provided with a heat exchanger and a blower inside, or a duct. For example, it may be configured such that conditioned air is supplied from a separate room.

When the conditioned air is supplied into the room, the air conditioner 1 changes the direction of discharge of the conditioned air into the room (described later), and a driving mechanism for driving the wind direction changing plate (described later). ) And a control unit (not shown).

Reference numeral 2 denotes a remote controller, which is configured to transmit or receive a signal for controlling the operation of the air conditioner 1 to / from the air conditioner 1, and to transmit or receive the signal. May be wireless or wired, and may be performed via a LAN.

When a wireless (for example, infrared) signal is used, the signal has a structure including a leader code indicating the start of the signal, a custom code indicating the manufacturer and model, a data code indicating a control signal, and an end code. Consists of a series of data. When other means are used, the data is in accordance with a format defined for each means.

The data code includes the operation / stop of the air conditioner, switching between cooling / heating / dehumidification, a set temperature, a detection value of a sensor mounted on the remote controller 2 for detecting ambient temperature, humidity, illuminance, etc. The value that determines the amount of air discharged into the room (the number of rotations of the blower motor), the angle of the wind direction change plate (the discharge direction of conditioned air) is set to any angle / automatic setting / periodically changes the angle within a predetermined range. The value includes a value for controlling a swing, a value for timer operation, and the like. These values are the values set by the switch 3 and the values automatically measured.

When the remote controller 2 receives a signal from the air conditioner 1, the data of the signal include an outside air temperature, an operation capability, an operation efficiency, and the like. These values are displayed on a display unit (for example, a liquid crystal display unit).

Reference numeral 5 denotes another air conditioner, for example, a humidifier,
Fan heater, floor heater, electric stove, air conditioner 1
An air conditioner that can discharge conditioned air in the same manner as above, or a controller (either wireless or wired, or further via a LAN) for controlling these operations may be used. Alternatively, any structure may be used as long as it can detect any one of the ambient humidity and can transmit a signal including the detected value, and if the air conditioner 1 can receive the signal (for example, the carrier frequency is the same). Good.

Therefore, in other air conditioners, if the communication means is wireless (for example, infrared rays), the transmitted signal is a common one composed of a reader code, a custom code, a data code, and an end code. The temperature value and the humidity value are included in the data code. The signal transmitted from the controller may have the same structure.

FIG. 2 is a sectional view of a main part of the air conditioner 1.
Numeral 6 denotes a wind direction changing plate for changing the direction of the discharged conditioned air to the left and right (connected by an interlocking plate so that a plurality of blades move simultaneously). Reference numeral 7 denotes a wind direction changing plate, which is a single blade that changes the direction of the discharged conditioned air up and down.

Reference numeral 8 denotes a step motor (drive mechanism) for changing the angle of the wind direction changing plate 6, which changes the rotation angle according to the output from the control unit, and changes the angle of the wind direction changing plate 6. For example, if the position of the wind direction changing plate 6 is 45 degrees leftward at 0 step, and the position of 45 degrees rightward is 480 steps, the step 0 position of the step motor 8 is adjusted to 45 degrees leftward, and then the step motor is forwarded. Or, if a negative output (pulse) is output, the step position can be arbitrarily controlled,
The angle of the wind direction changing plate 6 can be arbitrarily controlled.

The positive or negative output to the step motor 8 is periodically (every predetermined number (between 0 and 480)) inverted to periodically and continuously change the angle of the wind direction changing plate 6 right and left. It can be changed (swinged).

9 is a step motor (drive mechanism),
Like the step motor 8, the angle of the wind direction changing plate 7 is changed from horizontal to vertical (as shown).

In FIG. 2, as an example, reference numeral 10 denotes a refrigerant heat exchanger, which releases heat when condensing the internal working refrigerant or absorbs heat when evaporating the internal working refrigerant. The air taken in from the room by the blower motor 11 is
After heating / cooling to generate conditioned air, the air is discharged indoors.

The control unit is usually a remote controller 2
Air-conditioning operation (run / stop,
It controls operations such as switching between cooling / heating / dehumidification, capacity control based on the difference between the temperature and the set temperature, the number of rotations of the blower motor, and arbitrary setting / swing of the angle of the wind direction change plate.

At this time, the signal transmitted from the remote controller 2 is set when the custom code of the signal completely matches the custom code stored in the air conditioner 1 or in a range of higher-order bits in which compatibility can be ensured. When they coincide with each other, they are taken into the air conditioner 1 and operation control is performed based on the data code. At this time, the temperature value and / or the humidity value existing at a predetermined position in the data code are set to T1 and R1, respectively, and the driving capability and the rotation speed of the blower motor 11 are controlled by fuzzy calculation based on these values. It is.

Therefore, the signal transmitted from the other air conditioner 5 can be secured when the custom code completely matches the custom code stored in the air conditioner 1 as that of the other air conditioner or compatibility. When they match in the range of the upper bits, they are taken into the air conditioner 1. Next, the temperature value and / or the humidity value existing at a predetermined position in the data code are set as T2 and R2, respectively.

When the function of interlocking with another air conditioner is selected by the switch of the remote controller 2, the following operation is performed.

First, it is determined whether or not the deviation between the temperatures T1 and T2 is 2 degrees or more and whether or not the deviation between the humidity R1 and R2 is 10% or more. At least one of the former condition and the latter condition is determined. When the condition is satisfied, the wind direction changing plate is driven by the swing.

The determination of these conditions is made at predetermined time intervals (based on the size of the room or the maximum capacity of the air conditioner. For example, the maximum capacity is about 2.5 Kw and is about 10 minutes, but is not limited to this. T1, T2,
This is performed based on the values of R1 and R2.

Therefore, it is desirable that the values of T1, T2, R1, and R2 be updated within a predetermined time, and the remote controller 2 and other air conditioners 5 automatically update the values of T1, T2, R1, and R2 within a predetermined time. Configured for sending.

The time for maintaining the wind direction changing plate in the swing may be at least a predetermined time or longer, or until both of the above conditions are not satisfied. When the swing is released, the wind direction change plate is reset to the state before the start of the swing. When the wind direction changing plate is set to swing by the remote controller 2, the swing of the wind direction changing plate is maintained even after both of the above conditions are cancelled.

In the above two conditions, the deviation between the temperatures T1 and T2 is 2
The deviation of the humidity R1-R2 is not limited to 10% or more, but may be a condition for judging that a temperature or humidity deviation has occurred in the room. It may be replaced.

In the air conditioner configured as described above, when the function of interlocking with another air conditioner is selected, when the temperature / humidity is deviated in the room, the wind direction change plate is automatically swung. Then, the indoor air can be agitated to make the indoor temperature / humidity substantially uniform.

A wind direction changing plate for changing the discharge direction to left and right;
When equipped with a wind direction change plate that changes the discharge direction up and down, both wind direction change plates may swing simultaneously, and according to the maximum capacity of the air conditioner, when the capacity is large, swing the left and right wind direction change plates, When the ability is small, the upper and lower wind direction change plates may be swung.

[0036]

As described above, according to the present invention, the temperature / humidity value obtained from another air conditioner is used to determine the deviation of the room temperature / humidity, and the room air is stirred to obtain the temperature / humidity. Can provide a uniform air-conditioned space.
