Abstract

PURPOSE:To allow the adjustment of cold or hot air blowing direction to any desired direction from a position away from the unit by providing actuators that actuate air guide plates in the air outlet of an air conditioner, and operating the actuators by remote control. CONSTITUTION:When the air direction key of a transmitter 5 is pressed, a sensor 4 detects infrared rays to output signals, which are detected and decoded by a decoder 7, to an actuator circuit 8. The actuator circuit 8 consists of a vertical actuator circuit 13 and a lateral actuator circuit 14, and the circuits 13, 14 respectively operate a vertical motion motor 15 and a lateral motion motor 16 to control vertically-moved louvers 17 and laterally-moved louvers 18. The remote control can be done either by the wireless control or by the cable control.

Description

[Detailed Description of the Invention] Industrial Field of Use The present invention is applicable to detecting the direction of wind from installed equipment such as air conditioning equipment.
This relates to the function of remote control using a remote control means provided outside the machine.

Conventional configurations and their problems Traditionally, the direction of hot or cold air from an air conditioner was determined by a fixed louver installed at the outlet, or by a movable louver up, down, left or right, and manually set to the desired direction. Therefore, air conditioners with a variable louver configuration that can obtain the wind direction in any one direction are common.

In order to avoid discomfort when the wind hits the human body directly, in the case of a fixed looper, it is necessary to change the installation location of the air conditioner, and in the case of a variable looper, it is necessary to manually change the wind direction. be. In the latter case, the equipment may be installed in a location such as the ceiling where manual operation is difficult. On the other hand, if you want to perform rapid cooling or heating, you may want to direct the wind toward the human body and blow out cold and hot air in a concentrated manner, but it would be undesirable if the operation involved the same cumbersome operation as described above. .

OBJECTS OF THE INVENTION The present invention solves the problems of the prior art, and aims to provide a function for setting the direction of cold and hot air blown out from an air conditioner to an arbitrary direction at a position away from the equipment.

Structure of the Invention In order to achieve the object of the present invention, the present invention provides a wind direction control plate at the outlet for blowing out hot air or cold air, a drive unit for driving the wind direction control plate, and a drive unit that is controlled by remote control. It was driven.

Description of examples An embodiment of the present invention will be described below with reference to the drawings.

1 and 3 The air conditioner 1 has a cold/hot air outlet 2, a movable louver 3, a sensor 4 for receiving control signals sent from a transmitter 5, and controls the movable louver 3 using the control signals. It is composed of a control device 6.

The control device 6 includes a decoder 7 that demodulates and decodes the output of the sensor 4, a drive circuit 8 that drives the drive unit 9 based on a signal from the decoder 7, and a drive unit 9.

The drive unit 9 controls the movable louver a.

An example of wired remote control is shown in FIGS. 2 and 4. The air conditioner 1 controls the movable louver a by control signals sent from the cold/hot air outlet 2, the movable louver 3, and the controller 5'. The control device 6 is composed of a decoder 7 that demodulates and decodes the signal from the remote controller 5', a drive circuit 8 that drives the drive section 9 based on the signal from the decoder 7, and a drive section. It consists of 9.

An example of the remote control S is shown in FIG. Wavelength 0 for carrier
．． Infrared rays of about 8 to 0.9 μm are used, and control inputs are input using a key-type input method. The key types consist of a ``power'' key, a ``temperature control'' key, and a ``wind direction'' key. ・The ``power'' key turns the air conditioner's power on and off. The "temperature control" keys are 5 keys: 18, 20, 22, 24, and 26°C. The "wind direction" keys consist of two keys each for up and down, one key for up and down swing, two keys for left and right, and one key for left and right swing. As shown in FIG. 6, the transmitter 5 has a structure in which the battery power is turned on only when any key is pressed. Consisting of an encoder section 11 and a light emitting and modulating section 12, when a corresponding control key of the key switch section 10 is pressed, coding is performed in the encoder/coder section 11, and infrared light emitted by the light emitting and modulating section 12 is used as the coding signal. The modulated infrared rays are transmitted. FIG. 7 is a configuration diagram of the control device 6 and the movable louver 3. The air conditioner has been supplied with power to the control device 6 in advance and is in a state of waiting for a signal from the transmitter 5. When the "power" key of the transmitter S is pressed, the sensor 4 senses the infrared rays, and the output thereof is demodulated and decoded by the decoder 7. The decoded signal gives a start command to the air conditioner and activates the heat source or cold source. When you press the corresponding key for the desired temperature in "Temperature control" on the transmitter 5, the air conditioner similarly senses the instructed temperature as the set temperature, operates the heat/cold source to the set temperature, and maintains that temperature. Continue driving to ensure that. Also, when the "wind direction" key on the transmitter 5 is pressed, the sensor 4 similarly detects infrared rays, and the output is demodulated and decoded by the decoder 7. Each signal is discriminated and output to the drive circuit 8. The drive circuit 8 is a vertical drive circuit 1 driven by a vertical drive signal.
3 and a left-right drive circuit 14 driven by left-right drive signals, which drive the vertical drive motor 15 and the left-right drive motor 16 of the drive unit 9, respectively. The motors in the drive section are all DC motors and are river/pull. The vertical movable louver 17 is controlled by the vertical drive motor 15,
The left and right movable louvers 18 are controlled by the left and right drive motors 16 .

In wired control, the power to the controller S' is supplied simultaneously with the power to the air conditioner 10 control device 6. Furthermore, the remote control signal is directly input to the decoder 7, making the sensor 4 unnecessary. Below, the signal processing function and drive function are the same as those for wireless control.

FIG. 8 shows an example of the structure of the drive section and variable louver section.

The rotational speed of the drive motor 15 or 16 is reduced by a gear 21, 22, and the shaft 25 is rotated by an interlocking/worm gear 23 and a rotary gear 24.

The shaft 25 is supported by bearings 26 and 27, and the variable louver a is fixed, so that the variable louver a rotates as the shaft 25 rotates.

Effects of the invention (1) As long as the power cord of the air conditioner is plugged into an outlet, operation, temperature setting, and wind direction control can all be controlled by remote control without having to directly operate the air conditioner, which is convenient.

@) It is possible to control the temperature and wind direction while sensing the sensation of coolness in the space occupied by people.

(3) When rapid cooling or heating is desired, the wind direction can be directed directly toward the human body at any desired position, which is highly effective.

4) If you feel uncomfortable when the wind hits you directly, you can automatically control the air to avoid blowing the wind to your body.

(5) With wireless control, there is no need for floor or wall wiring between the air conditioner and the transmitter, so the living space is not disturbed and disconnection accidents can be avoided.
