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, sleep operation control for air conditioners was performed when the off timer was set (or when the sleep operation switch was set).
(when turned on), the indoor air volume was set to a gentle breeze and the temperature setting was adjusted. Additionally, the air conditioner stopped operating at the first set time.

Problems to be Solved by the Invention However, if the sleep mode switch is turned on immediately after the start of operation, the indoor air volume may become a breeze even though the room is not sufficiently cooled, or the set temperature may slide, resulting in insufficient cooling. The air conditioner did not feel any heat, and the cooling capacity decreased. This has led to problems such as it takes time to obtain sufficient comfort for a good night's sleep.

Furthermore, after the sleep mode was started, even when the outside temperature dropped during the night and air conditioning was no longer necessary, the system continued to operate until the initial set time, which caused an economical problem.

Furthermore, on hot nights such as tropical nights, if the cooling operation is stopped after the set time has elapsed, it becomes difficult to sleep again, causing problems such as not being able to sleep soundly.

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

That is, the indoor air volume is set to a light breeze, the set room temperature T ₀ is raised by a degree Celsius, and sleep operation is started. Then, after the second set time _t2 has elapsed since the start of the sleep operation, the outside air temperature T _put is detected and compared with the outside air set temperature T _S to determine, and if T _put ≦ T _S , the cooling operation is stopped. Also, the third set time t ₃ from the start of sleep driving
The cooling operation will also stop when the time period has elapsed.

In step 2, the first timer counts the first set time _t1 . In step 3, the room temperature _T1 is read by the room temperature detection element 2, and in step 4, it is compared with the set temperature _T0 stored in the A/D conversion circuit 52, and it is determined that the room temperature _T1 has reached the set temperature _T0 . If not, the process moves to step 5, and the LSI 24 determines whether the first set time _t1 has elapsed. here
