Abstract

본 발명은 공기조화기의 가스센서 제어방법에 관한 것으로 특히, 이전의 오염정도 검출전압(V3)에서 현재의 오염정도 검출전압(V)을 뺀 차전압(V4)을 구하는 과정과; 상기 차전압(V4)이 일정전압(V1) 미만인지를 검출하여 일정전압 미만이면 현재시간(t)이 일정시간(T1)을 경과되었는지를 검출하는 과정과; 상기에서 차전압(V4)이 일정전압(V1)미만이고 일정시간(T1)이 경과되었면 현재의 오염정도 검출전압(V)에서 표준전압(Vref)을 뺀 차전압(V2)을 산출하여 그 값이 제1절대값(Va)이상인가를 검출하는 과정과; 상기에서 차전압(V2)이 실내기의 풍량을 “약”으로 설정하되, 상기차전압(V2)이 제1절대값(Va) 미만이면 V에서 Vref을 뺀 차전압(V2)이 제2절대값(Vb)미만인가를 검출하는 과정과; 상기에서 차전압(V2)이 제2절대값(Vb) 미만이면 그에 상응하는 오염도를 표시하고 실내기 팬의 풍량을 “중”으로 설정하고, 차전압(V2)이 제2절대값(Vb) 이상이면 그에 맞는 오염도를 표시하고 풍량을 “강”으로 설정하는 과정으로 디스플레이부와 실내기 팬을 제어하므로서, 소비자가 정상적인 제품에 이상이 발생된 것으로 오인 혼동하는 것을 방지할 수 있음은 물론 제품의 신뢰도를 대폭 향상시킬 수 있는 등 매우 유용한 발명인 것이다.The present invention relates to a method of controlling a gas sensor of an air conditioner, and more particularly, to a method of controlling a gas sensor of an air conditioner, comprising: obtaining a difference voltage V4 obtained by subtracting a current pollution degree detection voltage V from a previous pollution degree detection voltage V3; Detecting whether the difference voltage V4 is less than a predetermined voltage V1 and detecting whether a current time t is less than a predetermined voltage and a predetermined time T1 has elapsed; If the difference voltage V4 is less than the predetermined voltage V1 and the predetermined time T1 has elapsed, the difference voltage V2 obtained by subtracting the standard voltage Vref from the current contamination level detection voltage V is calculated, Detecting whether the value is equal to or greater than the first absolute value Va; The differential voltage V2 obtained by subtracting Vref from V is smaller than the second absolute value Va when the difference voltage V2 is less than the first absolute value Va, (Vb); If the difference voltage V2 is less than the second absolute value Vb, the degree of pollution corresponding thereto is displayed and the air volume of the indoor fan is set to "medium". If the difference voltage V2 is equal to or greater than the second absolute value Vb It is possible to prevent the user from misunderstanding that the abnormality has occurred in the normal product by controlling the display unit and the indoor fan by the process of setting the air quantity to " It is a very useful invention.

Claims (1)

공기조화기내의 마이컴에서 이전의 오염정도 검출전압과 현재의 오염정도 검출전압을 읽어들여, 이전의 오염정도 검출전압에서 현재의 오염정도 검출전압을 뺀 차전압을 구하고 그때의 시간을 인크리먼트시키는 제1과정과; 상기 차전압이 일정전압 미만인지를 검출하여 일정전압 미만이면 현재시간이 일정시간을 경과되었는지를 검출하는 제2과정과; 상기에서 차전압이 일정전압 미만인 상태에서 일정시간이 경과되면 현재의 오염정도 검출전압에서 깨끗한 공기에서의 표준전압을 뺀 차전압을 산출하여 그 값이 제1절대값 이상인가를 검출하는 제3과정과; 상기에서 차전압이 제1절대값 이상이면 그때의 오염도를 표시하고 실내기의 풍량을 약으로 설정하되, 상기 차전압이 제1절대값 미만이면 현재의 오염정도 검출전압에서 표준전압을 뺀 차전압이 상기 제1절대값보다 높은 제2절대값 미만인가를 검출하는 제4과정과; 상기에서 차전압이 제2절대값 미만이면 그에 상응하는 오염도를 표시하고 실내기 팬의 풍량을 중으로 설정하고, 차전압이 제2절대값 이상이면 그에맞는 오염도를 표시하고 풍량을 강으로 설정하는 제5과정; 으로 이루어진 것을 특징으로 하는 공기조화기의 가스센서 제어방법.The microcomputer in the air conditioner reads the previous pollution degree detection voltage and the current pollution degree detection voltage and obtains the difference voltage obtained by subtracting the current pollution degree detection voltage from the previous pollution degree detection voltage and increments the time A first process; A second step of detecting whether the difference voltage is less than a predetermined voltage and detecting whether a predetermined time has elapsed since the voltage difference is less than a predetermined voltage; When a predetermined time elapses in a state where the difference voltage is less than a predetermined voltage, a difference voltage obtained by subtracting the standard voltage from clean air from the current contamination level detection voltage is calculated and a third step of detecting whether the difference is greater than a first absolute value and; If the difference voltage is greater than or equal to the first absolute value, the degree of contamination at that time is displayed and the air volume of the indoor unit is set to be weak. If the difference voltage is less than the first absolute value, Detecting whether the first absolute value is less than a second absolute value higher than the first absolute value; If the difference voltage is less than the second absolute value, the degree of contamination corresponding thereto is displayed and the air volume of the indoor unit fan is set to medium, and if the difference voltage is equal to or greater than the second absolute value, process; And a control unit for controlling the gas sensor. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
