Description

  The present invention relates to comfort control of an air conditioner having a cut-off timer function.

Conventionally, this type of technology is controlled so that a forced operation is performed for a certain period of time after the turn-off timer has expired, and then the dry or air blowing operation is continued for a certain period of time (see, for example, Patent Document 1).
JP-A-55-102852

  However, in the above-described conventional configuration, the operation before the end of the timer is always continued after the end of the turn-off timer, and thereafter, the cooling or blowing operation is performed for a predetermined time. The air conditioner continues to operate despite the fact that it is no longer necessary to operate, so it has problems in terms of energy conservation, which has become a hot topic in recent years, and health problems in order to keep the user on the wind. It was.

  The present invention solves the above-described conventional problems, and provides improved air-conditioning and comfortable air conditioning for users by performing operation according to the air conditioning load in the room even after the end of the turn-off timer. With the goal.

  In order to solve the above-described conventional problems, an air conditioner of the present invention includes a human body temperature detecting unit that detects a temperature near the human body, an outside air temperature detecting unit that detects an outdoor temperature, and an intake temperature of the air conditioner. A suction temperature detecting means for detecting air temperature, a temperature setting means for setting a control target room temperature of the air conditioner, and a cut-off timer for stopping the operation of the air conditioner when the operation time is compared with the timer set value and the timer set value is reached. Means, differential temperature determination means for determining whether or not a difference temperature between the suction temperature before the end of the timer operation ends and the control target room temperature is a predetermined value or more, an activity amount detection means for detecting an activity amount of a human body, In the determination result of the differential temperature determination means, when the differential temperature is equal to or greater than a predetermined value for a certain period of time and the amount of activity is equal to or greater than a certain value from the cut-off timer time, at least a first predetermined operation mode after the end of the deactivation timer During, it is provided with a control means for operating the air conditioner.

  As a result, when the air conditioning load is large after the turn-off timer operation, additional operation is performed, so that the user can go to bed without discomfort. Further, since the operation is minimized, unnecessary operation is not performed, and wasteful energy consumption can be prevented.

  Since the air conditioner of the present invention additionally operates when the air conditioning load is large after the turn-off timer operation, the user can go to bed without discomfort. Further, since the operation is minimized, unnecessary operation is not performed, and wasteful energy consumption can be prevented.

According to a first aspect of the present invention, there is provided a human body temperature detecting means for detecting a temperature in the vicinity of a human body, an outside air temperature detecting means for detecting an outdoor temperature, a suction temperature detecting means for detecting a suction temperature of the air conditioner, and an air conditioner A temperature setting means for setting the control target room temperature, a turn-off timer means for comparing the operation time with the timer set value and stopping the operation of the air conditioner when the timer set value is reached, and the suction temperature before the end of the turn-off timer operation Difference temperature determination means for determining whether the difference temperature between the control target room temperature and the control target room temperature is equal to or greater than a predetermined value, an activity amount detection means for detecting an activity amount of a human body, and the difference temperature in the determination result of the difference temperature determination means. Is equal to or greater than a predetermined value for a predetermined time, the air conditioner is operated for at least a first predetermined time as an operation mode after the end of the timer operation.
