Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wind direction control device for an air conditioner that controls the direction of air blowing into an air-conditioned space.

Conventional configuration and its problems The wind direction control device of a conventional air conditioner blows air to the left and right at a constant speed over a certain range. If there is a temperature difference in a space, it is difficult to air-condition that area compared to other areas.

OBJECT OF THE INVENTION Therefore, an object of the present invention is to enable air conditioning for a desired period of time when there is a temperature difference in an air-conditioned space.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a wind direction angle detection means arranged to synchronize with the rotation of a variable wind direction morph that changes the direction of air blowing to the left and right, and a wind direction angle detection means for detecting the wind direction angle, and a wind direction angle detection means installed at the left and right suction ports, respectively. It consists of a wind direction angle setting means for setting a predetermined wind direction angle according to the temperature of the temperature detection means, and a timer that stops the variable wind direction motor for a predetermined time when the set wind direction angle and the detected wind direction angle match. , when there is a temperature difference between the left and right suction ports, partial air conditioning is possible by partially discharging conditioned air for a long time.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 denotes an air conditioner main body, and a wide suction port 2 and a wide discharge port 3 are formed on the front surface. In the ventilation path from the suction port 2 to the discharge port 3, there is an indoor coil 4 facing the suction port 2.
A wind direction changing device 5 is arranged facing the air outlet 3, and an indoor blower 6 for circulating indoor air to the indoor coil 4 is arranged between them.

In the wind direction changing device 5, 7 is a variable wind direction motor;
is installed obliquely on the rotating shaft 9 of the variable wind direction motor 7,
Circular blade that changes the wind direction left and right, 10 is a variable wind direction motor 7
The wind direction angle is detected by a potentiometer which is attached to the rotating shaft 9 of the rotary shaft 9 so as to fit the shaft, and whose resistance value changes depending on the rotation angle. 11 is a first thermistor that detects the temperature of the air sucked in from the left side of the suction port 2, and 12I'i is a second thermistor that detects the temperature of the air sucked in from the right side of the suction port 2. It is something to do.

FIG. 2 is a block diagram of a control circuit in one embodiment of the present invention, in which reference numeral 13 is an AC power source, which is connected to the variable wind direction motor 7 via an operation switch 14 and an electromagnetic switch 15 of the main body 1. Ru. 16 is a wind direction angle setting circuit for comparing the first thermistor 11 and the second thermistor 12 and stopping the variable wind direction motor 7 at an angle that requires more air conditioning.

17 is a comparator which is connected to the voltage value of the wind direction angle setting circuit 16;
A voltage value of a potentiometer 10 which is attached to the rotating shaft 9 of the variable wind direction motor 7 and detects the rotation angle, that is, the wind direction angle by a change in resistance value is input, and the wind direction angle detected by the potentiometer 10 is set to the wind direction angle. When the angle set by the layer setting circuit 16 is larger than the angle set by the layer setting circuit 16, the logic output is r.
Outputs HJ level. The output of the comparator 17 is input to a timer 18. Reference numeral 19 is a stop time setting volume for stopping the wind direction at a desired wind direction angle for a desired time, and is inputted to the timer 18. The timer 18 outputs the rHJ level when the input is at the pulling level, and when the input is at the rHJ level, the timer 18 outputs f for the time set by the stop time setting volume 19.
-5 level is output.

The output of the timer 18 is input to an electromagnetic switch 15 that drives and controls the variable wind direction motor 7.

The operation of the above configuration will be explained below.

When the indoor fan 6 is operating, the air that has circulated on the left side of the room is sucked in from the left side of the suction port 2, and its temperature is detected by the first thermistor 11, and the air that circulates on the left side of the room is detected from the right side of the suction port 2. The circulated air is sucked in and its temperature is
The thermistor 12 detects this. The first thermister 11 and the second
Wind direction angle setting circuit 1 based on detection output with thermistor 12
Determine the output of 6. For example, when the first thermistor 11 detects a higher temperature than the second thermistor 12 during cooling operation, the wind direction angle setting circuit 16 sets a wind direction angle such that the wind direction is directed to the left. When the stop time setting volume 19 is set to the desired time and the operation switch 14 is turned on, the wind direction angle detected by the wind direction angle detection potentiometer 1o does not reach the wind direction angle set by the wind direction angle setting circuit 16. , the output of the comparator 17 outputs the rLJ level, the output of the timer 18 outputs the "H" level, and the electromagnetic switch 15 is excited, so the variable wind direction motor 7 operates,
The wind direction starts to move left and right. When the wind direction angle detected by the wind direction angle detection potentiometer 10 reaches the wind direction angle set by the wind direction angle setting circuit 16 due to the rotation of the variable wind direction motor 7, the output of the comparator 17 outputs "i (J level), and the timer Since the output 18 outputs the l'-LJ level for the time set by the stop time setting volume 19, the electromagnetic switch 15 is demagnetized during this time, so the variable wind direction motor 7 stops.When the set time elapses, the variable wind direction motor 7 stops. , the output of the timer 18 returns to r ] (J level, the electromagnetic switch 16 is energized again, the variable wind direction motor 7 is activated, and the wind direction starts to move left and right. Thereafter, the setting is repeated for a predetermined time each time the wind direction changes left and right. Air is blown intensively at the specified wind direction and angle.

Effects of the Invention As is clear from the above description, the air direction control device for an air conditioner of the present invention includes an indoor coil disposed facing the suction port, an indoor blower that ventilates the indoor coil, and an air blower operated by the blower. a variable wind direction motor that changes the direction of the wind toward the discharge port from side to side; a wind direction angle detection means installed to synchronize with the rotation of the variable wind direction motor to detect the wind direction angle; A temperature detection means, a wind direction angle setting means for setting a predetermined wind direction angle according to the temperature of the temperature detection means, a wind direction angle set by the wind direction angle setting means and a wind direction angle detected by the wind direction angle detection means. It consists of a timer that stops the variable wind direction motor for a predetermined period of time when they match, so if there is a temperature difference in the air-conditioned space, air can be blown for a longer period of time to areas that require more air conditioning than to other areas. is possible.
