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-mentioned conventional problem, and after the turn-off timer expires, depending on the indoor / outdoor air conditioning load, the indoor air is discharged to the outside and the outdoor air is introduced indoors, thereby improving the energy saving performance. It aims to provide comfortable air conditioning to users.

  In order to solve the above-described conventional problems, an air conditioner of the present invention includes a near-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. Detecting suction temperature detecting means, temperature setting means for setting a control target room temperature of the air conditioner, and switching timer means for stopping the operation of the air conditioner when the operation time is compared with the timer setting value and the timer setting value is reached And ventilating means for discharging indoor air to the outdoors and introducing the outdoor air indoors. As an operation mode after the end of the timer operation, the temperature near the human body is higher than the first predetermined temperature and the outdoor temperature is When the temperature is lower than the second predetermined temperature, outdoor air is introduced indoors by the ventilation means, and when the temperature near the human body is higher than the first predetermined temperature and the outdoor temperature is higher than the second predetermined temperature, cooling or dehumidification is performed. Drive It is provided with a control unit.

  As a result, when the air conditioning load is large, additional driving is performed, and the user can go to bed without discomfort. Moreover, when the air conditioning load is small, unnecessary operation is not performed, exhausting high-temperature indoor air, and introducing air having a lower temperature than the outdoors can prevent wasteful energy consumption.

  The air conditioner of the present invention is additionally operated when the air conditioning load is large, and the user can go to bed without discomfort. Further, when the air conditioning load is small, unnecessary cooling operation is not performed, the indoor air having a high temperature is exhausted, and the air having a lower temperature than the outside is introduced, so that the room temperature can be lowered and wasteful energy consumption can be prevented.

The first invention is a sensor means for detecting the temperature in the vicinity of the human body, an outside air temperature detecting means for detecting the outdoor temperature, a suction temperature detecting means for detecting the suction temperature of the air conditioner, and a temperature setting for setting the room temperature. Means, and a time-out timer means 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, and the indoor air is discharged to the outside and the outdoor air is introduced to the indoor If the temperature near the human body is higher than the first predetermined temperature and the outdoor temperature is lower than the second predetermined temperature after the end of the timer operation, the indoor air is exhausted to the outside by the ventilation means and the outdoor To introduce indoor air. Further, when the temperature near the human body is higher than the first predetermined temperature and the outdoor temperature is higher than the second predetermined temperature, the cooling or dehumidifying operation is performed. As a result, when the air conditioning load is large, additional driving is performed, and the user can go to bed without discomfort. Further, when the air conditioning load is small, wasteful energy consumption can be prevented without impairing comfort by performing ventilation operation without excessive cooling operation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a control block diagram of the air conditioner according to Embodiment 1 of the present invention.

  In FIG. 1, the off timer means 1 constantly compares the timer set value with the operation time, and transmits a stop signal of the air conditioner to the control means 7 when the timer set time is reached. After receiving this stop signal, the operation of the air conditioner is determined according to the detected values of the human body vicinity temperature detection means 2 and the outside air temperature detection means 3.

  About the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 2 is a flowchart showing the operation of the air conditioner according to the first embodiment of the present invention. In step 1 and step 2, the cut-off timer time is determined. If the timer time is reached, the air conditioner is stopped in step 3. In step 4, the temperature near the human body is detected. At this time, if the temperature in the vicinity of the human body is lower than the predetermined temperature T1 ° C., it is not necessary to operate the air conditioner. Therefore, in step 6, the stop state by the timer operation is continued. If the temperature in the vicinity of the human body is higher than the predetermined temperature T1 ° C., the outside air temperature is determined in step 5. At this time, if the outside air temperature is higher than the predetermined temperature T2 ° C., it is determined that the air conditioning load is large after the turn-off timer operation, and the air conditioner is cooled in step 7. If the outside air temperature is lower than the predetermined temperature T2 ° C., the air conditioner is ventilated in step 8. Thereby, indoor high temperature air is discharged | emitted outdoors and room temperature can be lowered | hung by introduce | transducing outdoor low temperature air indoors.

  As described above, in this embodiment, as the operation mode of the air conditioner after the end of the timer operation, when the temperature near the human body is low, the stop state is continued, the temperature near the human body is high, and the outside air temperature is also By performing additional cooling operation in a high air conditioning load state, the user can go to bed without discomfort. Also, if the temperature in the vicinity of the human body is high and the outside air temperature is low, ventilation operation is performed. It is possible to lower the room temperature without performing the operation, to realize a comfortable air conditioning, and to prevent useless energy consumption from the viewpoint of energy saving.

  As described above, the air conditioner according to the present invention additionally performs the cooling operation when the air conditioning load is large in the operation mode after the turn-off timer operation, and the user can go to sleep without feeling uncomfortable. In addition, when the air conditioning load is small, ventilation operation is performed instead of cooling operation, so that unnecessary energy consumption can be prevented without excessive cooling operation. It is.
