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 according to the present invention includes a human body temperature detecting unit that detects a temperature near the human body, a suction temperature detecting unit that detects 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 sensor for detecting the amount of activity of the human body, and the difference temperature in the determination result of the difference temperature determination means Control means for operating the air conditioner for at least a first predetermined time as an operation mode after the end of the switching timer operation when the predetermined amount of time is greater than the predetermined value for a certain period of time or when the amount of activity for a certain period of time from the switching timer time is equal to or greater than the predetermined value. Those were.

  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.

1st invention, human body vicinity temperature detection means which detects temperature near a human body, suction temperature detection means which detects the suction temperature of an air conditioner, temperature setting means which sets the control target room temperature of an air conditioner, Compared with the timer set value, the operation time is compared with the timer set value, and the cut-off timer means for stopping the operation of the air conditioner, and the difference temperature between the suction temperature and the control target room temperature before the end of the cut-off timer operation is predetermined time. When the temperature difference is a predetermined value or more for a predetermined time in the determination result of the temperature difference determination means for determining whether or not the value, an activity amount sensor for detecting the amount of activity of the human body, and the temperature difference determination means,
The air conditioner is operated for at least a first predetermined time as an operation mode after the end of the cut-off timer operation.

  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.

  According to a second aspect of the present invention, when the temperature difference between the room temperature and the set temperature is equal to or greater than a predetermined value after the end of the turn-off timer operation, or when the amount of activity reaches a predetermined value or more after the turn-off timer time, the air conditioner for the first predetermined time The operation of operating the air conditioner again when the room temperature reaches the set temperature even after the air conditioner is stopped is repeated for the first predetermined number of times.

  Accordingly, when the room temperature rises after the end of the turn-off timer and a temperature difference of a predetermined value occurs between the set temperature and the air conditioner is operated for a predetermined time and a predetermined number of times, more comfortable sleep can be provided.

  In the third aspect of the invention, in the operation of the air conditioner after the end of the timer operation, the set temperature is shifted by a predetermined value in a direction in which the compressor is more likely to stop than before the timer operation.

  Accordingly, it is possible to prevent over-cooling by suppressing the air-conditioning ability to a low level, and wasteful use of energy and health disturbance of the user due to over-heating.

  In the fourth aspect of the invention, in the operation of the air conditioner after the end of the off timer operation, the air volume of the indoor fan is made smaller than that before the off timer operation.

  This can prevent the user from hitting a strong wind during sleep.

  In the fifth aspect of the invention, in the operation of the air conditioner after the end of the off timer operation, the set temperature is shifted in accordance with the outside air temperature in a direction in which the compressor is more likely to stop than before the off timer operation.

  Accordingly, it is possible to prevent the wasteful use of energy and the health disturbance of the user due to the excessive warming by suppressing the air conditioning capability to be low according to the air conditioning load.

  In the sixth aspect of the invention, in the operation of the air conditioner after the end of the off timer operation, the air volume of the indoor fan is made smaller according to the outside air temperature than before the off timer operation.

  Thereby, since it drive | operates with the air volume according to an air-conditioning load, it can prevent that a user hits a strong wind at the time of low load during sleep.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

If the temperature difference is equal to or greater than the predetermined value for a certain time, or if the amount of human activity from the timer time is equal to or greater than the certain value for a certain time in Step 5, the air conditioner is operated for a predetermined time in Step 6 to Step 8. If the temperature difference is not greater than or equal to the predetermined value for a certain time in step 4, and if the activity amount is not greater than or equal to the predetermined value for a certain time in step 5, the air conditioner remains stopped.

  As described above, in the present embodiment, the operation mode of the air conditioner after the end of the timer operation is turned off, and the difference between the suction temperature and the set temperature before the timer operation ends, and the amount of activity from the timer time. Whether or not to operate air-conditioned air is determined, and even when operating, the operation is limited to a predetermined time.

  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.
