Abstract

PURPOSE: To prevent surroundings of a user asleep near a floor surface from having low temperature lower than set temperature by stopping operation of a compressor for each predetermined time, directing an air direction blade to increase the amount of diffused air from a fan, and after a predetermined time returning the air direction blade horizontally and returning the compressor and the fan to capability control operation. CONSTITUTION: A timer is started, a compressor, a vertical air direction blade 5, and a fan 7 are subjected to capability operation, and the vertical air direction fan 5 is operated in a user preferable direction. When the timer counts 10 minutes, the compressor is stopped and the vertical air direction blade 5 is directed downward and circulation operation where the amount of air from the fan 7 is increased is performed for 2 minutes to reverse and mix an air flow in a room whereby temperature locarization in the room is prevented. When the time is not over after the lapse of 2 minutes, the timer is reset for new start of the operation, and the compressor is returned to functional operation and the vertical air direction blade 5 is turned to a previous position to return the operation of the fan 7 to the functional operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner equipped with a rotating type vertical wind direction blade installed on the upper side wall of a room.

[0002]

2. Description of the Related Art Conventionally, this type of air conditioner is actually fair.
As disclosed in Japanese Patent No. 4424, an air conditioner has been proposed which creates a more comfortable indoor environment by making the temperature distribution in the room uniform by interlocking the movement of the rotary up / down airflow blades and the air volume of the indoor blower. There is.

[0003]

In such a conventional air conditioner, when the cooling air-conditioning timer is operated, the vertical wind direction blades do not rotate, and the air-conditioning blades operate in a substantially horizontal direction in a fixed direction so that the cool air directly hits a person. The device was designed so as not to disturb the sleep of the user. However, when sleeping, there is no movement of people in or out of the room, so the air in the room does not move much and the air conditioner is operated with a constant air flow in a certain direction. Around the floor of the user who was sleeping, the temperature around the user was lower than the set temperature and the sleep was disturbed.

[0004]

The present invention focuses on this point and solves the above-mentioned drawbacks. In particular, the configuration is such that the rotation of the compressor and the blower is controlled by the temperature difference between the room temperature and the set temperature, and the louver is used. In an air conditioner equipped with a timer for good night operation, the vertical airflow vanes are rotated by a motor to perform cooling operation in a substantially horizontal direction. With the wind direction blades facing downward and the blower air volume of the blower increased, the vertical wind direction blades were returned to the substantially horizontal position before rotation after a certain period of time, and the circulation operation for returning the compressor and the blower to the capacity control operation was repeated. It is a thing.

The timer setter 11 of the operation portion during normal cooling operation
By setting the timer setting time T by pressing the sleep switch 13 in step 1, sleep operation starts, and in step 2, the control unit 9 reads the timer setting time T and the current time T1. Timer set time T
If is not set, the value set when the timer was used last time is read.

Next, if the current time T1 is compared with the timer setting time T in step 3 and the time is up, the operation of the air conditioner is stopped in step 4, and if it is before the timer setting time T, the step is performed. At 5, the timer T2 is started. At this time, the compressor 14, the upper and lower wind direction blades 5 and the blower 7 are in the normal operation state of cooling, that is, the compressor 14 and the blower 7 perform capacity control operation, and the upper and lower wind direction blades 5 are from a substantially horizontal direction depending on a user's preference. The operation is performed at the position of the direction, and the operation is continued until the timer T2 reaches 10 minutes in step 6.

When the timer T2 has passed 10 minutes, the routine proceeds to step 7, where the compressor 14 is stopped and the vertical airflow direction vanes 5 are turned downward to perform a circulation operation for increasing the air volume of the blower 7 for 2 minutes to flow the air in the room. By inverting and stirring, temperature unevenness in the room is prevented. After the lapse of 2 minutes and returning to step 3 and when the time is not up, the timer T2 is reset and newly started as described above to return the compressor 14 to the capacity control operation, and the vertical wind direction blade 5 is rotated to the previous position, The operation of the blower 7 is also returned to the capacity control operation.

As described above, by periodically changing the blowing direction of the relatively warm air in the upper part by approximately 90 degrees and blowing it downward, the air in the room is agitated to eliminate room temperature unevenness, and the lower part of the room is compared to the set temperature. It prevents the user from sleeping too cold and waking up or falling asleep.
