상기와 같이 구성되고 제어되는 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured and controlled as described above are as follows.
먼저, 공기조화기에 전원이 인가되면 전원부(1)에서는 입력되는 전압을 구동전압으로 바꾸어 각부에 공급하게 되고, 실내온도센서부(2)와 실외온도센서부(3)에서는 실내온도(Ti)와 실외온도(To)를 센서로 감지하여 마이콤(4)에 입력시키게 된다.First, when power is supplied to the air conditioner, the power supply unit 1 converts the input voltage into a driving voltage and supplies the power to each unit. In the indoor temperature sensor unit 2 and the outdoor temperature sensor unit 3, the indoor temperature Ti and The outdoor temperature (To) is detected by the sensor and input to the microcomputer (4).
따라서 마이콤(4)에서는 소정의 프로그램에 의하여 실내외 온도감지단계(200)(201)로 가서 상기 실내온도센서부(2)와 실외온도센서부(3)로 부터 계속해서 각각의 실내온도(Ti)와 실외온도(To)를 입력받는 동시에 운전판단단계(202)로 가서 공기조화기가 운전되고 있는가를 판단하여 운전중이면 마이콤(4)에서는 팬구동부(5)의 운전상태에 따른 제어신호를 출력 공기조화된 공기를 토출시켜 실내공기를 조화하게 되고, 이어서, 마이콤(4)에서는 실내외온도차산출단계(203)로 가서 자체의 타이머카운터로 상기 운전시작부터 소정시간(10분간)을 카운트하고, 이어서, 타이머카운터에 의해 소정시간(10분간)이 경과하면 마이콤(4)에서는 상기 실내온도센서부(2)와 실외온도센서부(3)에서 각각 감지된 실외온도(To)로 부터 실내온도(Ti)를 감산하여 온도차(TE)를 산출하고, 온도차 비교단계(204)로 가서 상기 소정시간(10분후) 감지온도의 온도차(TE)가 소정시간경과후 임의로 설정된 소정온도(Ts)보다 큰가를 비교하게 된다.Therefore, the microcomputer 4 goes to the indoor and outdoor temperature sensing steps 200 and 201 according to a predetermined program, and continues each indoor temperature Ti from the indoor temperature sensor unit 2 and the outdoor temperature sensor unit 3. And the outdoor temperature (To) are input to go to the operation determination step 202 to determine whether the air conditioner is running, and if the microcomputer 4 is operating, the control signal according to the operation state of the fan driver 5 output air conditioning The discharged air is discharged to match the indoor air. Then, the microcomputer 4 proceeds to the step of calculating the indoor / outdoor temperature difference 203 and counts a predetermined time (10 minutes) from the start of operation with a timer counter of its own. After a predetermined time (10 minutes) has elapsed by the counter, the microcomputer 4 receives the indoor temperature Ti from the outdoor temperature To detected by the indoor temperature sensor 2 and the outdoor temperature sensor 3, respectively. Subtract the temperature difference (TE), In step 204, the temperature difference comparing step 204 compares whether the temperature difference TE of the detected temperature is greater than a predetermined temperature Ts set after a predetermined time elapses.
이때, 상기 온도차(TE)가 제3도의 (b)도에 도시한 바와 같이 소정시간(10분)경과후에는 온도차(TE)가 소정온도(Ts)보다 작게되면, 마이콤(4)에서는 소정시간경과판단단계(206)로 가서 타이머카운터로 상기 소정시간경과후부터 소정시간(1시간 30분)간 카운트를 하게되고, 소정시간 카운트가 완료되었는가를 판단하여 소정시간 카운트되었으면 온도판단단계(207)로 가서 상기 소정시간(10분)경과전의 실내온도(Ti)와 소정시간(1시간 30분)경과후 실내온도(T2)를 감산하여 그 온도차가 소정온도(Tm)보다 큰가를 판단하여 크지않으면, 경보구동단계(208)로 가서 경보부(6)를 제어하여 경보음을 발하여 실내도어가 열려있음을 알려주게 되고, 한편, 상기 온도차비교단계(204)에서 소정시간(10분)경과후 온도차(TE)가 소정온도(Ts)보다 큰가를 판단하여 제3도의 (a)에 도시한 바와같이 상기 소정시간 경과후 온도차(TE)가 소정온도(Ts)보다크면 마이콤(4)에서는 리세트 단계(210)로 가서 타이머카운터에서 카운트한 소정시간(1시간 30분)을 리세트시키고, 경보정지단계(211)로 가서 경보를 정지하게 되는 것이다.At this time, when the temperature difference TE is smaller than the predetermined temperature Ts after a predetermined time (10 minutes) as shown in (b) of FIG. 3, the predetermined time in the microcomputer 4 Go to the elapsed judgment step 206 and count by the timer counter for a predetermined time (1 hour 30 minutes) from the elapse of the predetermined time, and if the predetermined time count is determined by determining whether the predetermined time count is completed, go to the temperature judgment step 207. If the temperature difference before the predetermined time (10 minutes) elapses and the room temperature (T2) after the predetermined time (1 hour 30 minutes) elapses, it is determined whether the temperature difference is greater than the predetermined temperature (Tm). Go to the alarm drive step 208 to control the alarm unit 6 to sound an alarm to inform that the indoor door is open, meanwhile, in the temperature difference comparison step 204 after a predetermined time (10 minutes) elapsed temperature difference (TE) ) Is determined to be greater than the predetermined temperature Ts and is shown in FIG. Likewise, if the temperature difference TE is greater than the predetermined temperature Ts after the predetermined time elapses, the microcomputer 4 goes to the reset step 210 and resets the predetermined time (1 hour 30 minutes) counted by the timer counter and alarms. Go to the stop step 211 is to stop the alarm.
즉 예를들면, 상기 소정온도 Ts = 4℃, T = 2℃라고 설정한 상태에서 운전전 실외온도(To)가 35℃, 실내온도(Ti)가 34℃이었고 그후 소정시간(1시간 30분)경과후 실내온도가 33℃일 경우, 상기 소정시간(10분)경과후 온도차(TE)는 To=Ti=35-34℃=1℃이므로, 상기 소정온도(Ts)와 비교하였을때 온도차(TE)는 소정온도(Ts)보다작고 운전전 실내온도와 소정시간(1시간 30분)경과후 실내온도와의 온도차가 상기 소정온도(Tm)보다 작게되면 경보를 발하여 실내도어가 열려있음을 알려주게 되는 것이다.That is, for example, the outdoor temperature (To) was 35 ° C and the room temperature (Ti) was 34 ° C before operation in the state where the predetermined temperature Ts = 4 ° C and T = 2 ° C was set, and then a predetermined time (1 hour 30 minutes). After the elapsed room temperature is 33 ° C., the temperature difference (TE) after elapse of the predetermined time (10 minutes) is To = Ti = 35-34 ° C. = 1 ° C., and thus the temperature difference (Ts) is compared with the predetermined temperature (Ts). TE) is less than the predetermined temperature (Ts), and if the temperature difference between the room temperature before operation and the room temperature after a predetermined time (1 hour 30 minutes) is less than the predetermined temperature (Tm), an alarm is issued to inform that the indoor door is open. Will be given.
이상에서 설명한 바와같이 본 발명은 실내.외 센서부를 통해서 실내외 온도를 계속 감지하고, 실외온도와 실내온도와의 온도차를 산출하여 소정온도와 비교 판단한후 온도차가 소정온도보다 작을 경우와, 소정시간 카운트한후 감지된 실내온도와 운전전 실내온도와 온도차를 산출하여 소정온도 비교한후 소정온도보다 작을 경우에 경보를 발하여 사용자에게 실내도어가 열려있음을 알려줌으로써 운전중 실내도어가 열려 있음으로해서 야기되는 불필요한 구동에 따른 전력소비를 낭비하게 되고, 뿐만 아니라 실내 공기조화효율을 크게 저하시키게 되는 문제점을 해소할 수 있는 효과를 제공하게 되는 것이다.As described above, the present invention continuously detects the indoor / outdoor temperature through the indoor / outdoor sensor unit, calculates a temperature difference between the outdoor temperature and the indoor temperature, compares the predetermined temperature with a predetermined temperature, and counts a predetermined time, when the temperature difference is smaller than the predetermined temperature. After calculating the difference between the detected indoor temperature and the pre-operation room temperature and the predetermined temperature, the alarm is issued when the temperature is less than the predetermined temperature and the user is informed that the indoor door is open. Wasted power consumption due to unnecessary driving is to be provided, as well as to provide an effect that can solve the problem of greatly reducing the indoor air conditioning efficiency.
