The present invention relates to an air conditioner equipped with a device.

(Prior art) As a conventional air conditioner of this type, for example,
There was one as shown in Japanese Patent No. 8-88546. Fourth
The figure is a mechanical diagram of the main parts of the conventional air conditioner described in the publication, and FIG. 5 is a diagram explaining its operation. In these figures, 101 is an air conditioner, and this air conditioner 101 is provided with vertically swinging type wind direction control plates 102, 102, 102 as a wind direction control device, and these wind direction control plates 102, 102.102 are integrally and pivotally connected via a connecting rod 103.

A rotating cam + is connected to the connecting rod 103 via a link 104.
05 are interlocked and connected, and a limit switch 106 is provided to act on the rotating cam 105, and the wind direction control plates 102, 102, 102 are in a horizontal blowing state (
Limit switch 106 is OFF when the wind direction is A-C)

The limit switch 106 is turned on when the air is blowing downward (the wind direction is C-B).

And the blower controller 1 of the fan motor 107 of the blower.
When the limit switch 106 is OFF, the fan motor 107 rotates at a constant speed without sending the signal from the I/f signal generator +09. On the other hand, when the limit switch 106 is turned on, the rotation speed of the fan motor 107 is controlled by the signal from the 1/f signal generator 109, and the air volume when the air from the air conditioner +01 hits the occupant directly is controlled. Configured to control and improve comfort.

(Problems to be Solved by the Invention) 1. In the case of the conventional example having such a configuration, the air volume is controlled depending on whether the wind direction control plates 102, 102, 102 are in a horizontal blowing state or a downward blowing state. When the air conditioner is near the air conditioner, the wind blows strongly.
There is a drawback that the air volume fluctuates depending on the distance from the air conditioner, such as the wind becoming weaker as you move away from the air conditioner, resulting in a loss of comfort.

The present invention has been made in view of these circumstances, and it improves comfort by providing wind at a constant speed to occupants regardless of changes in wind direction or the occupant's position in the room.
− The purpose is to

2), a heat exchanger (1), an air volume control device (7) that adjusts the amount of air blown from the air blower (2), and an air blower (2).
An operation control signal is sent to the wind direction control device (8) that changes the direction of wind blowing from the air to the horizontal direction and the downward direction, the operation control device main body (9), and the operation control device main body (9). In an air conditioner equipped with a remote control device (I3), the remote control device (13) is equipped with a wind speed device that detects the wind speed around it and outputs a wind speed signal to the operation controller main body (9). A sensor (14) and an air volume control means for operating the air volume 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).

(Function) When entering a 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 sent to the operation controller body (9).
The operation control unit (9) compares the detected wind speed with the set wind speed, and if the detected wind speed is higher than the set wind speed, the air volume is decreased; conversely, if the detected wind speed is lower than the set wind speed, the The air volume control device (7) is actuated by the air volume control means to increase the air volume, so that the wind speed near the remote control device (I3) is maintained at the set wind speed.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. FIG. 1 is a longitudinal 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 that drives the blower 2. Reference numeral 4 denotes a wind direction control plate, which is integrally and pivotally connected via a link 5, and the link 5 and a motor 6 are interlocked and connected, and as the motor 6 is driven, the wind direction control plate 4 can be swung to change the direction in which the air is blown out between the horizontal direction and the downward direction.

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

Each of the air volume control device 7 and the air direction control device 8 is
It is operated in response to a control signal from an operation controller main body 9 provided in the indoor unit of the air conditioner. Further, 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 indoor temperature at a set temperature.

The operation controller main body 9 includes a CPU 11 and a memory (RO
M and RAM) I2 are provided.

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

Further, although not shown, signals from various switches such as an operation switch provided in the indoor unit are inputted to the operation controller main body 9.

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 minute electric power, and the other thermistor receives heat from the heater while receiving heat from the blower. Various types of devices, such as being arranged in a position that also receives wind, detecting the degree of cooling caused by the wind from the blower based on the difference in output voltage from both thermistors, and detecting the wind speed based on that. Can be hired.

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

The CPU 11 is provided with an air volume control means that automatically controls the air volume control device 7 in response to the startup of the air conditioner or the ON operation of the sleep switch 16, and also automatically controls the wind direction control device 8, etc. The control operation of the CPU 11 will be explained next with reference to the flowchart of FIG.

First, it is determined whether the operation switch is turned on, that is, whether the air conditioner is started (S1). If the air conditioner is started, the process proceeds to step S2, and it is determined whether the sleep switch 16 is turned on.

Here, if the sleep switch 16 is turned on at bedtime, the process moves to step S3, where a control signal is output to the wind direction control device 8, a control output is output to the motor 6, and the wind direction control board 4 is brought into a downward blowing state. At the same time, the wind speed sensor 14 of the remote control device 13 outputs a wind speed signal to detect the wind speed (S4), and then it is determined whether the wind speed is a target value that is the set wind speed (S5).

If the wind speed is not the target value, the process moves to step S6, where a control signal is output to the air volume control device 7, a control output is output to the fan motor 3, and the process continues at step S4 until the wind speed reaches the target value.
The process then cycles through step S6.

When the wind speed reaches the target value, the process moves to step S7, where 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, which is the set temperature. (S8).

8- If the temperature is not the target value, the compressor IO is driven until the temperature detected by the temperature sensor 15 reaches the target value, and when the temperature reaches the target value, the process moves to step S9 and the wind direction control device 8, a control output is output to the motor 6 to set the wind direction control board 4 in a horizontal blowing state, and a wind speed signal is output from the wind speed sensor 14 of the remote control device 13 to detect the wind speed (5IO) , After that, it is determined whether the wind speed is the target value which is the set wind speed (Sll).

If the wind speed is not the target value, the process moves to step SI2, a control signal is output to the air volume control device 7, and the fan motor 3 is
Step S until the wind speed reaches the target value.
Step SI2 is cycled from IO.

When the wind speed reaches the target value, the process moves to step SI3, where 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, which is the set temperature. (S14).

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 moves to step S15 and output of the wind speed signal and temperature signal is stopped. Then, step SI6
Then, it is determined whether there is a setting change, that is, whether a setting switch for air volume or temperature has been operated, and if there is a setting change, the process returns to step S1.

At this time, since the sleep switch 16 is not normally turned on, the process jumps from step S2 to step SIO, and the processes from step S10 to step St6 are 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 to further improve comfort, but in the present invention, only the wind speed is maintained at the target values. It is fine as long as it does so.

(Effects of the Invention) As described above, according to the present invention, the remote control device (13) placed near the resident operates the air volume control means both at startup and when changing the wind direction. Since the wind speed near is maintained at the set wind speed, even if the wind direction changes,
In addition, no matter where the occupant is in the room, they can receive wind at a constant speed, making it possible to sufficiently and favorably improve comfort.

Especially when going to bed, for example, turn off the sleep switch (1).
6) By operating a dedicated switch for sleeping, the wind direction will automatically change after the set time has elapsed, even if the wind direction is initially directed downward so that the wind directly hits the occupants. When applied to an air conditioner in which the air blows out horizontally, it is possible to control the wind speed so that it does not automatically change as the wind direction changes, thereby further improving comfort.
