Abstract

PURPOSE:To realize comfortable air conditioning sufficient for sound sleep more quickly and permit economical operation by a method wherein cooling or heating operation under an ordinary setting is effected until a room temperature arrives at a set temperature or a set time elapses, thereafter, the operation of an air-conditioning machine enters into a good-night operation and the flow rate of indoor air is reduced to obtain a breeze while the set temperature is slid. CONSTITUTION:Cooling or heating operation is started, a timer counts a predetermined time (ts), a room temperature T1 is read by a room temperature detecting element 2 and is compared with a set temperature T0, stored in an A/D converting circuit 52, then, the room temperature T1 and the predetermined time (ts) are decided by a LSI 24 whether the room temperature T1 has arrived at the set temperature T0 and the predetermined time (ts) has elapsed or not. When the set temperature T0 and the predetermined time (ts) are satisfied, a good-night operation is started, the flow rate of indoor air is reduced to obtain breeze (step 7) and the set temperature is slid.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in sleep operation control of an air conditioner.

Conventional technology Conventionally, the sleep operation control of an air conditioner was performed by setting the indoor air volume to a gentle breeze and sliding the set temperature when the off timer was set (or when the sleep operation switch was turned on).

Problems to be Solved by the Invention However, when the sleep mode switch is turned on immediately after the start of operation (in this case, the indoor air volume becomes a breeze even though the room has not cooled down (or warmed up) enough), causing the set temperature to drop. If the room slides, you will not feel sufficiently cool (or warm), and the cooling capacity (or heating capacity) will decrease. Is there a problem with it, such as how long it takes to get it?

In view of the above-mentioned conventional problems, the present invention implements comfortable sleep control without sacrificing the advantages of the conventional technology.

Firstly, the present invention, as shown in FIG. a comparison/judgment means that compares and makes a determination between nf and the room temperature T1 detected by the system; a set time detection means that detects that a set time has elapsed from the start of operation and outputs an output; an indoor air volume switching means that switches the indoor air volume; and an indoor thermo setting. In an air conditioner equipped with a set temperature sliding means etc. that slides the temperature TO, the set temperature T is set during cooling operation.
.

≧Room temperature Tt (during heating operation, set temperature TO≦room temperature TI)
At this time, the comparison and determination means outputs an output signal, and the output means drives the indoor air volume switching means and the set temperature sliding means based on this output signal or the output signal of the set time detection means. It is a complicated thing.

Furthermore, during cooling, the room temperature changes in the opposite direction, eventually resulting in a gradual rise in the room temperature. The control signal operation in this case is the same as that during heating (the operating point is different), so the explanation will be omitted.

After this, quiet and economical operation can be achieved by sliding the set temperature.
