It is configured to improve the comfort by controlling the air volume when the wind from the aircraft 101 directly hits the occupants.

(Problems to be solved by the invention) However, in the case of the conventional example having such a configuration, the wind direction control plates 102, 102, 102 only control the air volume according to the horizontal blowing state or the downward blowing state,
There is a specific air volume control state in each of the horizontal blowing state and the downward blowing state, the wind hits strongly when near the air conditioner, but the wind weakens when moving away from the air conditioner. There was a drawback that the air volume fluctuated due to the distance from the aircraft and the comfort was impaired.

The present invention has been made in view of such circumstances, and improves the comfort by giving a constant wind speed to the occupants regardless of the wind direction change and the position of the occupants in the room. To aim.

(Means for Solving the Problems) In order to achieve such an object, the present invention provides a blower (2), a heat exchanger (1), and an air volume for adjusting the amount of air blown from the blower (2). A control device (7), a wind direction control device (8) for changing the blowing direction of the wind from the blower (2) to a horizontal direction and a downward direction, an operation controller main body (9), and an operation controller main body ( An air conditioner comprising a remote control device (13) for transmitting an operation control signal to the operation control device body (9), which is provided in the remote control device (13) and detects a wind speed around the remote control device (13). ) Which outputs a wind speed signal to the wind speed sensor (14), and which controls the air flow rate control device (7) to maintain the detected wind speed at the set wind speed in response to the wind speed signal from the wind speed sensor (14). And means.

(Operation) When entering the room and starting the air conditioner or changing the wind direction, the wind speed signal from the wind speed sensor (14) provided in the remote control device (13) is used as the operation controller body (9). Then, in the operation controller main body (9), the detected wind speed is compared with the set wind speed, and if the detected wind speed is larger than the set wind speed, the air volume is reduced. Conversely, if the detected wind speed is smaller than the set wind speed, The air flow rate control means operates the air flow rate control device (7) to increase the air flow rate so that the wind speed near the remote control device (13) is maintained at the set wind speed.

(Example) Hereinafter, the Example of this invention is described in detail based on drawing. FIG. 1 is a vertical sectional view of an indoor unit of an air conditioner according to an embodiment of the present invention. In this figure, 1 is a heat exchanger, 2 is a blower, and 3 is a fan motor for driving the blower 2. Reference numeral 4 denotes an airflow direction control plate, which is integrally and swingably interlocked via a link 5, and the link 5 and the motor 6 are interlockingly connected, and the wind direction control plate is driven by the driving of the motor 6. 4 is swingable so that the blowing direction of the wind can be changed between the horizontal direction and the downward direction.

As shown in the block diagram of FIG. 2, the blower 2 is configured to change the number of revolutions thereof to adjust the air volume by the control output from the air volume control device 7, and the wind direction control plate 4 is It is configured to change the blowing direction of the wind between a horizontal blowing state and a downward blowing state by a control output from the wind direction control device 8.

Each of the air volume control device 7 and the wind direction control device 8 is
The air conditioner is operated in response to a control signal from the operation controller main body 9 provided in the indoor unit. A control output is output from the operation controller main body 9 to the compressor 10, and the rotation speed of the compressor 10 is adjusted to maintain the room temperature at the set temperature.

The operation controller main body 9 includes a CPU 11 and a memory (ROM and RA
M) 12 and.

13 is a wireless type remote control device, which is a wind speed sensor.
14, a temperature sensor 15, a sleep switch 16, and other various operation switches (not shown) are provided. A signal from the remote operation device 13 is input to the CPU 11, and in response to the signal, the fan motor 3, motor 6 and the compressor 10, respectively.

Although not shown, the operation controller main body 9 receives signals from various switches such as an operation switch provided in the indoor unit.

As the wind speed sensor 14, for example, a pair of thermistors is used, one of which directly measures the temperature of a heater driven by a small amount of electric power, and the other thermistor receives heat from the heater while receiving wind from a blower. Various types can be adopted such as being arranged at a position, detecting the degree of cooling by the wind from the blower based on the difference between the output voltages from both thermistors, and detecting the wind speed based on that.

Further, as the temperature sensor 15, various types such as a thermistor can be adopted.

In the CPU 11, the air conditioner startup and sleep switch 16
An air volume control means for automatically controlling the air volume control device 7 in accordance with the ON operation of is provided, and the air flow direction control device 8 and the like are automatically controlled. Next, the control operation of the CPU 11 will be described with reference to the flowchart of FIG.

First, it is determined whether or not the operation switch is turned on, that is, whether or not the air conditioner is activated (S1), and if activated, the process proceeds to step S2 to determine whether or not the rest switch 16 is turned on.

Here, if you turn on the sleep switch 16 at bedtime,
In step S3, a control signal is output to the wind direction control device 8, and a control output is output to the motor 6 to bring the wind direction control plate 4 into a downward blowing state, and a wind speed signal is output from the wind speed sensor 14 of the remote control device 13. The wind speed is output to detect the wind speed (S4), and then it is determined whether the wind speed is the target value that is the set wind speed (S5).

If the wind speed is not the target value, the process proceeds to step S6, a control signal is output to the air volume control device 7, a control output is output to the fan motor 3, and steps S4 to S6 are circulated until the wind speed reaches the target value. .

When the wind speed reaches the target value, the process proceeds to step S7, the temperature sensor 15 of the remote control device 13 outputs a temperature signal to detect the temperature, and then it is determined whether the temperature is the target value that is the set temperature. Yes (S8).

If the temperature is not the target value, the compressor 10 is driven until the temperature detected by the temperature sensor 15 reaches the target value, and if the temperature reaches the target value, the process proceeds to step S9 and a control signal is sent to the wind direction controller 8. It outputs a control output to the motor 6 to bring the wind direction control plate 4 into a horizontal blowing state and a remote control device.
A wind speed signal is output from the wind speed sensor 14 of 13 to detect the wind speed (S10), and then it is determined whether the wind speed is a target value that is the set wind speed (S11).

If the wind speed is not the target value, the process proceeds to step S12, the control signal is output to the air volume control device 7, the control output is output to the fan motor 3, and the wind speed reaches the target value in step S10.
Through step S12.

When the wind speed reaches the target value, the process proceeds to step S13, the temperature sensor 15 of the remote control device 13 outputs a temperature signal to detect the temperature, and then it is determined whether the temperature is the target value that is the set temperature. Yes (S14).

If the temperature is not the target value, drive the compressor 10 until the temperature detected by the temperature sensor 15 reaches the target value, and if the temperature reaches the target value, move to step S15 and stop the output of the wind speed signal and the temperature signal. Then, after that, the process proceeds to step S16, and it is determined whether or not there is a setting change, that is, whether or not the setting switch for the air volume and the temperature is operated, and if there is a setting change, the process returns to step S1. At this time, the sleep switch 16 is not normally turned on, so that the process jumps from step S2 to step S10, and the processing from step S10 to step S16 is performed as described above.

In the above embodiment, the wind speed and temperature near the remote control device 13 are maintained at the target values, and the comfort can be further improved.However, as the present invention, only the wind speed is maintained at the target value. Anything can be done.

(Effects of the Invention) As described above, according to the present invention, the remote control device (13) which is placed near a resident by operating the air volume control means at both the startup and the wind direction change. Since the wind speed near the room is maintained at the set wind speed, the wind can be received at a constant wind speed no matter where the occupant is in the room, even if the wind direction is changed, and comfort is improved sufficiently and satisfactorily. I can do it now.

Especially at bedtime, for example, sleep switch (1
By operating the sleep-only switch called 6), etc., even if the wind direction is downward so that the wind directly hits the occupants at the beginning, the wind direction will automatically change after the set time elapses. When applied to an air conditioner of the type that is changed to a horizontal blowing state, it is possible to control so that the wind speed does not naturally change in accordance with the change in the wind direction, and comfort can be further improved.
