Abstract

PURPOSE:To cause a room temperature to rapidly reach a predetermined set temperature irrespective of setting of a sleep timer function by delaying starting of a set temperature correction of a room temperature effected by a sleep timer a period of time. CONSTITUTION:In the case where a sleep timer acts or time associated with the sleep timer is up, an air conditioner is stopped and the sleep timer is restarted without being put out of function, counter means 6 delays starting of a set temperature correcting function of the sleep timer, for example, 30 minutes when operating condition judging means 5 confirms that a set temperature is high and the sleep timer is not put out of function. In the meantime, a room temperature is decreased through room temperature control effected by a room temperature sensor 10 and is held at a set temperature as it is for 30 minutes when a predetermined period of time lapses and correction of sleep set temperatures is started. After 30 minutes lapses, the set temperature is raised 0.5 deg.C, and thereafter such action is repeated and counting of the timer is continued.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling an air conditioner, and more particularly to a method for controlling an indoor temperature of an air conditioner for setting a "good night timer" by a wired remote controller or the like.

[0002]

2. Description of the Related Art Conventionally, in an air conditioner in which operation control is performed by a remote controller (so-called wired remote controller) connected by a signal line, when a sleep timer function provided in the air conditioner is set by the remote controller,
After a certain period of time, for example, 30 minutes, from the start of operation, in order to maintain comfort at bedtime, increase the set temperature in the room by the specified temperature range (for example, 0.5 ° C) to correct the set temperature to a higher temperature and cool it down. After that, the set temperature is similarly corrected every predetermined time, and the operation of the air conditioner is stopped by the time-up of the sleep timer. During operation of the good night timer function, forcibly stop the operation of the air conditioner, or when the operation of the air conditioner is stopped due to the time up of the good night timer, without canceling the good night timer setting of the remote control device, When the operation of the air conditioner is restarted in that state, the good-night timer starts timing at the same time as the operation starts, and after a predetermined time, the set temperature is corrected by increasing the set temperature range, so that it works to raise the set temperature. There is a problem that the room temperature does not reach a comfortable temperature because it prevents the room temperature from falling due to room temperature control. In this way, the correction of the set temperature by the timer function and the correction of the set temperature by the room temperature control by the room temperature sensor simultaneously act, so that an appropriate set temperature cannot be set, and as a result, the indoor temperature control remains insufficient. Therefore, the operation of the air conditioner was stopped, and the indoor temperature could not be quickly reached to a comfortable indoor temperature.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. When the "sleep timer" is stopped during operation or when it is stopped by the timer function, regardless of the timer function, It is an object of the present invention to provide an air conditioner control method capable of setting an appropriate set temperature in an indoor temperature state and starting operation.

[0004]

In order to achieve the above object, a good night timer setting means, a driving state judging means for judging whether the night time timer is running or stopped by a control section of an air conditioner, and Equipped with counting means for measuring time, either stop the operation of the air conditioner while the sleep timer is operating, or stop the sleep when the sleep timer ends and restart the sleep timer with the sleep timer still set. When starting, the time to start the correction of the set temperature of the room temperature by the good night timer is delayed by a predetermined time according to the set time of the good night timer.

[0005]

According to the above construction, the good night timer setting means set in the operation section comprising the yard remote control device and the control section of the air conditioner determine whether the air conditioner is started or stopped by the time up of the good night timer. The operating state determination means and the counter means that starts at the same time as the operation of the good night timer and counts the timer operating time are provided, and the good night timer is set by the operation unit to start the operation of the air conditioner and the good night timer operates. However, if the sleep timer is running or the sleep timer has timed out and the air conditioner has stopped operating, restarting the operation as it is will set the start time for the temperature correction of the room temperature by the sleep timer to the sleep timer. Depending on the specified time, the start of the room temperature sensor may be delayed by a predetermined time, during which the room temperature sensor room Start the operation of the air conditioner with temperature control, and so as to reach the room temperature immediately comfortable temperature. Also, by delaying the start time of the set temperature correction of the room temperature by a predetermined time, the interval between the end of the delay time and the set time of the good night timer is narrowed, and the number of set temperature corrections by the good night timer is reduced to raise the set temperature. The temperature can be kept low and the rise in the room temperature during this time can be kept low.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram of a main part showing a configuration of the present invention, in which an operating unit 1 including a wired remote controller has operating condition setting means 2 for setting operating conditions of an air conditioner,
A night timer setting means 3 for setting the start time and operation time of the night timer is provided, and is connected to the air conditioner body by a signal line. The air conditioner main body is provided with a control unit 4 that controls the operation of the air conditioner. The control unit 4 includes an operation state determination unit 5 that determines the operation state of the air conditioner by the operation unit 1 and a sleep timer. Counter means 6 for counting the operating time and the delay time of the present invention, and a memory 7 for storing a set value according to other operating conditions are provided.
The indoor temperature is detected by the indoor temperature sensor 10, the operation control of the air conditioner is obtained from the operation state determination means 5, the counter means 6, and the memory 7 by the arithmetic means 8, and the operation of the compressor 9 is controlled. .

FIG. 2 is a time chart showing the details of the present invention. FIG. 2 (a) is a time chart of the sleep timer during the cooling operation. For example, the sleep timer starts when the set temperature in the room is 25 ° C. Maintain the same set temperature (25 ° C) for 30 minutes, raise the set temperature by 0.5 ° C after 30 minutes, and then set the set temperature after 30 minutes.
The operation of raising the temperature by 0.5 ° C is repeated and the operation is completed within 1.5 hours. When the sleep timer reaches the set time (2 hours), the set temperature is kept high at 26.5 ° C to prevent excessive coldness at bedtime. (B) is the case where the sleep timer is operating or the sleep timer has timed out and the air conditioner has stopped, the sleep timer function is not released,
The figure shows the fluctuation of the room temperature when restarted as it is. At restart, set temperature is 25.0 ℃
However, the compressor 9 is driven to lower the indoor temperature by controlling the indoor temperature by the indoor temperature sensor 10.
As a result, the room temperature was gradually decreased, and after 30 minutes had elapsed, the room temperature was controlled to raise the room temperature slightly by raising the room temperature by 0.5 ° C and then lower the room temperature again. And it took extra time to reach a comfortable room temperature. (C) shows the control method of the present invention, and when restarting, when the operating state determination means 5 confirms that the set temperature is in a high state and the sleep timer function is not released, the counter means 6 determines a predetermined value. The start of the set temperature correction function of the good night timer is delayed for a time (for example, 30 minutes), and the room temperature is lowered by the indoor temperature control by the indoor temperature sensor 10 during this time, and the good night set temperature correction starts after a predetermined time. Then, the set temperature is maintained as it is for 30 minutes, the set temperature is increased by 0.5 ° C. after the lapse of 30 minutes, and this operation is repeated thereafter, and the timer count is continued during this period. At this time, the room temperature has reached the preset temperature (25 ℃) or less,
The sleep timer function suppresses an excessive rise in the room temperature, and the sleep timer expires to end the sleep timer function, and the room temperature is controlled so that it matches the set temperature.
