본 발명은 공기조화기에 관한 것으로, 특히 실내의 오염정도에 따라 운전시간의 누적비율을 달리하여 필터의 청소필요 여부를 판단하는 공기청정장치의 청소시기판단장치 및 방법에 관한 것이다.The present invention relates to an air conditioner, and more particularly, to an apparatus and method for determining a cleaning time of an air cleaning device, which determines whether a filter needs to be cleaned by varying an accumulation ratio of an operation time according to the degree of pollution of an indoor room.

일반적으로 공기조화기는 압축, 응축, 팽창, 증발의 4과정을 연속적으로 반복 수행하면서 실내를 냉방시키게 되는데, 이는 냉매의 증발이 이루어지는 과정에서 주변의 공기로부터 열을 흡수하는 증발기가 내설된 실내기와 냉매의 응축이 일어나며 주변으로 열을 방출하는 응축기가 내설되는 실외기가 별도로 구성되며 이들은 각각 실내, 외에 설치된다.In general, the air conditioner cools the room while repeatedly performing four processes of compression, condensation, expansion, and evaporation. This is an indoor unit and a refrigerant having an evaporator that absorbs heat from the surrounding air during the evaporation of the refrigerant. Condensation takes place and the outdoor unit is built with a condenser that emits heat to the surroundings, each of which is installed indoors and outside.

제1도는 분리형 공기조화기의 실내기를 도시한 것으로 이에 도시한 바와 같이, 케이스(10)의 전면에는 흡입구(20)가 설치되고, 흡입구(20)의 하측에는 토출부(12)가 설치된다. 흡입구(20)의 전방에는 상하 회동가능하도록 케이스(10)의 상측에 결합된 그릴부재(13)가 설치되며, 흡입구(20)에는 필터(11)가 배치되어 공기가 함께 흡입되는 먼지 등의 불순물을 걸러준다.FIG. 1 illustrates an indoor unit of a separate air conditioner. As shown in the drawing, an inlet 20 is installed on a front surface of the case 10 and a discharge unit 12 is installed below the inlet 20. The grill member 13 coupled to the upper side of the case 10 is installed at the front of the inlet 20 so as to be able to rotate up and down, and the filter 11 is disposed at the inlet 20 so that impurities such as dust are sucked together with air. To filter.

이러한 공기조화기에 있어서 전원이 인가되면 도시되지 않은 실내팬이 구동되며 실내팬의 구동에 의하여 실내의 공기가 흡입구로 흡입되게 되고, 이때 흡입되는 공기에 포함된 먼지 및 부유물 등이 흡입구(20)측에 설치된 필터(11)에 부착되게 된다. 따라서, 공기조화되어 실내로 토출되는 공기를 청정하게 할 수 있는 것이다.When power is applied in the air conditioner, an indoor fan (not shown) is driven, and indoor air is sucked into the intake port by driving the indoor fan. At this time, dust and floating matters contained in the sucked air are drawn into the intake port 20 side. It is attached to the filter 11 installed in. Therefore, it is possible to clean the air that is air-conditioned and discharged into the room.

또한, 이러한 분리형 공기조화기는 운전시간을 적산하여 즉, 실내팬의 구동시간을 적산하여 일정시간(예를 들면 200-300HR)이 경과되면 필터(11)에 부착된 먼지 및 부유물을 제거하도록 사용자에게 필터청소시기를 시각적 또는 청각적으로 표시한다. 사용자는 일정 표시수단에 의해 필터청소시기를 인식하고 필터(11)에 부착된 먼지를 제거한 뒤 필터의 청소시기를 적산하는 타이머의 리세트스위치를 온 시켜 적산된 운전시간을 클리어 시키고 차후에 필터청소필요여부를 판단하기 위하여 운전시간을 다시 적산하게 된다.In addition, such a separate air conditioner to the user to accumulate the operating time, that is, to accumulate the driving time of the indoor fan to remove dust and floating matter attached to the filter 11 after a predetermined time (for example 200-300HR) elapsed. Display the filter cleaning time visually or audibly. The user recognizes the filter cleaning time by a certain display means, removes the dust attached to the filter 11, turns on the reset switch of the timer that accumulates the cleaning time of the filter, and clears the accumulated operating time, and the filter needs to be cleaned later. The operation time is re-integrated to determine whether or not.

그러나, 공기조화기가 설치된 주위환경조건에 따라 오염발생량에는 차이가 생길 수 있다. 따라서, 주위조건에 따른 오염발생량 등을 배제하고 공기조화기의 운전시간만을 적산하여 필터의 청소시기를 감지하는 경우에는 공기의 오염도가 낮은 지역에서 판단된 청소시기가 적절하다면 오염도가 높은 지역에서는 이미 청소시기가 늦어 냉난방효율이 저하되게 되며, 반대로 오염도가 높은 지역에 맞게 청소시기가 설정되었다면 오염도가 낮은 지역에서는 사용자가 불필요하게 자주 필터를 점검하게 되는 문제점이 있었다.However, the amount of pollution may vary depending on the environmental conditions in which the air conditioner is installed. Therefore, if the cleaning time of the filter is detected by integrating only the operating time of the air conditioner and excluding the amount of pollution caused by the ambient conditions, if the cleaning time determined in the area with low air pollution is appropriate, it is already in the area with high pollution. When the cleaning time is late, the cooling and heating efficiency is lowered. On the contrary, when the cleaning time is set according to a high pollution area, there is a problem that a user frequently checks the filter unnecessarily in a low pollution area.

따라서, 본 발명은 이러한 문제점을 해결하기 위하여 안출된 것으로 그 목적은 실내의 오염정도에 따라 운전시간의 누적비율을 달리함으로써 주위환경조건을 고려하여 정확한 시기에 필터를 청소할 수 있도록 하는 공기조화기의 필터청소시기판단장치 및 방법을 제공하는 것이다.Accordingly, the present invention has been made to solve the above problems and the object of the present invention is to change the cumulative ratio of operation time according to the degree of pollution in the room, so that the filter can be cleaned at the correct time in consideration of the environmental conditions.

제2도는 본 발명에 따른 공기조화기의 제어블럭도를 도시한 것으로, 실내공기의 오염정도를 감지하는 실내오염 감지부(110)와, 사용자로부터 냉방 또는 난방의 운전종류 및 실내팬의 구동속도를 조절하는 풍량 등을 입력받는 기능선택부(120)와, 필터를 청소하고 난 후 누적된 운전시간을 리세트시키는 누적시간 리세트부(130)와, 실내팬의 구동을 제어하는 실내팬 구동부(140)와, 현재 운전상태 및 필터의 청소시기를 사용자가 알 수 있도록 표시하는 표시부(150)와, 운전중에 일정 누적비율에 의하여 적산된 운전시간을 운전종료시점에서 저장하는 운전시간기업부(160)와, 상기 운전시간기업부(160)에 기억된 누적된 운전시간을 필터의 청소필요여부를 판단하기 위하여 미리 설정된 일정 기준시간과비교하여 청소시기를 판단하는 제어부(100)를 구비한다.2 is a control block diagram of the air conditioner according to the present invention, the indoor pollution detection unit 110 for detecting the pollution of the indoor air, the type of operation of cooling or heating from the user and the driving speed of the indoor fan Function selection unit 120 for receiving the amount of air to adjust the control unit, the accumulated time reset unit 130 for resetting the accumulated operating time after cleaning the filter, and the indoor fan drive unit for controlling the driving of the indoor fan 140, the display unit 150 for displaying the current operation state and the cleaning time of the filter so that the user can know, and the driving time company unit for storing the operation time accumulated by a certain cumulative ratio during operation at the end of the operation ( 160, and a control unit 100 that determines the cleaning time by comparing the accumulated operating time stored in the driving time company unit 160 with a predetermined predetermined reference time to determine whether the filter needs cleaning.

이와 같은 구성에 있어서, 상기 운전시간기업부(160)는 제어부(100)에서 적산되는 운전시간을 입력받아 저장하며 상기 제어부(100)에 누적시간리세트부(130)로부터 리세트신호가 입력되면 저장된 운전누적시간을 클리어 시키며, 이는 단전 또는 정전에 대비하여 EEPROM(Electrically Erasable and Programmable ROM)에 의하여 양호하게 구현된다.In such a configuration, the driving time enterprise unit 160 receives and stores the driving time accumulated in the control unit 100, and when a reset signal is input from the cumulative time reset unit 130 to the control unit 100. Clear the stored accumulated operation time, which is well implemented by EEPROM (Electrically Erasable and Programmable ROM) in case of power failure or power failure.

상기 실내오염감지부(110)는 반도체 가스센서에 의하여 양호하게 구현가능하며, 일반적으로 반도체 가스센서는 접촉연소방식의 센서로서 알루미나 소결체에 Pt, Pd 등을 증감 촉매로서 첨가한 SnO2, ZnO나 αFe2O3등을 소결하여 만든 산화물 반도체로 치환한 것이다. 이중 SnO2를 이용한 반도체 가스센서는 반도체 표면에 가스가 흡탁착함에 따라 반도체의 전도가 변화되는 것을 이용한 것이며 센서에는 히터가 내장되어 이에 따라 반도체의 감지부를 200℃-300℃로 가열하여 가스의 흡탁착속도를 빠르게 한다.The indoor pollution detection unit 110 can be implemented well by a semiconductor gas sensor. In general, a semiconductor gas sensor is a contact combustion type sensor, in which SnO 2 , ZnO, αFe is replaced with an oxide semiconductor made by sintering 2 O 3 or the like. The semiconductor gas sensor using SnO 2 is a method in which the conduction of semiconductor is changed as gas is adsorbed on the surface of the semiconductor. Speeds up deposition.

또한, 상기 제어부(100)는 공기조화기의 운전이 개시되면 상기 운전시간 기억부(160)로부터 적산된 운전시간을 입력받아 현재의 운전시간을 일정 누적비율로 적산하게 되는데, 이때 상기 실내오염감지부(110)에서 감지된 실내의 오염정도를 판단하여 오염정도에 따라 운전시간의 누적비율을 변경시킨다. 즉, 실내의 오염정도가 A이하면 운전시간의 누적비율을 예를 들면 1로 하고, 실내의 오염정도가 A이상 B이하이면 누적비율을 C1(단, C11)으로, 실내의 오염정도가 B이상 C이하이면 누적비율을 C2(단, C2C1)등으로 실내의 오염정도에 따라 누적비율에 차이를 두어 운전시간을 적산하게 된다.In addition, when the operation of the air conditioner starts, the control unit 100 receives the accumulated operation time from the operation time storage unit 160 and integrates the current operation time with a predetermined cumulative ratio, wherein the indoor pollution detection The degree of contamination of the interior detected by the unit 110 is determined and the cumulative ratio of the driving time is changed according to the degree of contamination. That is, if the indoor pollution level is less than A, the cumulative ratio of the driving time is 1, for example, and if the indoor pollution level is more than A or less than B, the cumulative ratio is C1 (C11), and the indoor pollution level is B. If it is less than or equal to C, the cumulative ratio is C2 (however, C2C1), and the operation time is accumulated by varying the cumulative ratio according to the degree of pollution in the room.

이와 같은 본 발명에 따른 공기조화기의 필터청소시기 판단방법을 제3도에 도시한 플로우차트를 참조하여 상세하게 설명하면 다음과 같다. 먼저 단계(s10)에서 공기조화기의 운전이 온 되면 단계(s12)로 진행하여 실내오염감지부(110)에 의하여 실내의 오염도를 감지하게 된다. 단계(s14)에서는 상기 단계(s12)에서 감지한 실내의 오염정도를 일정 기준치인 A와 비교하게 되며, 비교결과 실내의 오염정도가 A이하이면 단계(s16)로 진행하고 실내의 오염정도가 A이상이면 단계(s22)로 진행하여 오염정도를 판단하게 된다.The filter cleaning time determination method of the air conditioner according to the present invention will be described in detail with reference to the flowchart shown in FIG. First, when the operation of the air conditioner is turned on in step s10, the process proceeds to step s12 to detect the pollution level of the room by the indoor pollution detection unit 110. In step s14, the degree of contamination of the room detected in step S12 is compared with a predetermined reference value A. If the result of the comparison is that the degree of contamination of the room is less than or equal to A, the process proceeds to step s16 and the degree of contamination of the room is A If abnormal, the process proceeds to step s22 to determine the degree of contamination.

단계(s16)에서는 상기 단계(s14)의 판단결과 실내의 오염정도가 A이하이므로 운전시간의 누적비율을 1로 하여 운전시간기억부(160)로부터 이전에 누적적산된 운전누적시간(T)을 인출하여 현재의 공기조화기의 운전에 따라 운전누적시간(T)을 1씩 증가시키게 된다. 단계(s18)에서는 상기 단계(s16)에서 1씩 증가된 운전누적시간을 필터의 청소필요여부를 판단하기 위하여 미리 설정된 일정 기준시간과 비교하고 비교결과 운전누적시간이 기준시간이하이면 상기 단계(s10)이하를 반복수행하고 운전누적시간이 기준시간이상이면 단계(s20)으로 진행하여 사용자가 알 수 있도록 외부에 시각적 또는 청각적으로 청소시기를 표시한다. 따라서, 사용자가 적절한 시기에 필터를 청소할 수 있도록 하여 공기조화기의 냉 난방효율의 저하 및 실내공기의 오염을 방지할 수 있게 된다.In step s16, since the indoor pollution degree is less than A as a result of the determination in step s14, the cumulative driving cumulative ratio of the driving time is set to 1, and the accumulated cumulative driving time T previously accumulated from the driving time storage unit 160 is calculated. Withdrawal increases the operation accumulation time T by 1 according to the operation of the current air conditioner. In step s18, the accumulated operation time increased by 1 in the operation s16 is compared with a predetermined reference time to determine whether the filter needs cleaning, and if the accumulated operation time is less than the reference time, the operation s10 Repeat the following steps and if the cumulative operation time is more than the reference time to proceed to step (s20) to display the cleaning time visually or acoustically to the user to know. Therefore, the user can clean the filter at an appropriate time, thereby preventing the lowering of the heating efficiency of the air conditioner and the contamination of the indoor air.

상기 단계(s14)의 판단결과 실내의 오염정도가 A이상이면 단계(s22)로 진행하여 실내의 오염정도를 일정 기준치인 B와 비교하며, 비교결과 실내의 오염정도가 A이상 B이하이면 단계(s24)로 진행하여 현재 운전시간의 경과에 따라 운전시간기억부(160)로부터 인출한 운전누적시간(T)을 C1(단, C11)의 비율로 누적연산한다. 이는 상기 단계(s22)의 비교결과 현재 실내공기의 오염정도가 상기 단계(s16)에서 운전누적시간의 누적비율을 1로 했을 때보다 심하므로, 같은 시간에 필터에 부착되는 먼지 및 부유물의 양이 더 증가하게 되므로 운전누적시간(T)의 누적비율이 1일 때보다 필터의 청소시기를 단축시켜 좀더 효율적이고 정확하게 필터의 청소필요여부를 판단하기 위함이다.As a result of the determination of the step (s14), if the indoor pollution degree is A or more, proceed to step (s22) and compare the indoor pollution degree with a predetermined reference value B. In operation S24, the accumulated operation time T drawn from the operation time storage unit 160 is accumulated at a ratio of C1 (C11) as the current operation time elapses. As a result of the comparison of the step (s22), since the pollution degree of the current indoor air is more severe than when the cumulative ratio of the cumulative operation time is 1 in the step (s16), the amount of dust and suspended matter adhering to the filter at the same time is increased. In order to determine whether the filter needs to be cleaned more efficiently and accurately by shortening the cleaning time of the filter than when the cumulative ratio of the accumulated operation time (T) is one.

또한, 상기 단계(s22)의 비교결과 실내의 공기오염도가 B이상이면 단계(s26)으로 진행하여 상기 단계(s12)에서 감지한 실내의 공기오염도를 일정기준치인 C(단, BC)와 비교하며, 상기 단계(s26)의 비교결과 실내의 공기오염도가 B이상 C이하이면 단계(s28)에서 공기조화기의 운전시간의 경과에 따라 상기 단계(s24)에서의 누적비율인 C1보다 큰 C2의 누적비율로 운전누적시간(T)을 누적적산하게 된다. 또한, 상기 단계(s26)의 비교결과 실내의 공기오염도가 C이상인 경우에는 단계(s30)으로 진행하여 운전누적시간(T)의 누적비율을 C3로 하여 누적적산하게 된다.In addition, if the air pollution degree in the room as a result of the comparison of the step (s22) B or more proceeds to step (s26) and compares the air pollution degree of the room detected in the step (s12) with a predetermined reference value C (but BC) When the air pollution degree in the room is greater than or equal to B or less than C, the accumulation of C2 larger than C1, which is the cumulative ratio in step S24, in accordance with the passage of the operating time of the air conditioner in step S28 Cumulatively accumulate the accumulated operation time T as a ratio. In addition, when the air pollution degree in the room is C or more as a result of the comparison of step (s26), the process proceeds to step (s30) and accumulates by accumulating the cumulative ratio of the driving accumulation time (T) as C3.

따라서, 상기 단계(s16)의 누적적산된 운전누적시간을 단계(s18)에서 일정 기준시간과 비교한 바와 같이, 상기 단계(s24), (s28), (s30)에서 일정 누적비율인 c1, c2, c3로 적산된 운전누적시간(T)을 단계(s18)에서 일정 기준시간과 비교하여 필터의 청소필요여부를 판단하여 청소가 필요하게 되면 외부에 필터의 청소시기를 사용자가 알 수 있도록 시각적 또는 청각적으로 표시하게 된다.Therefore, as compared with the accumulated accumulated accumulated operation time of step (s16) and a predetermined reference time in step (s18), a predetermined cumulative ratio c1, c2 in the step (s24), (s28), (s30) In operation s18, the accumulated cumulative operation time T is compared with a predetermined reference time in step s18 to determine whether the filter needs to be cleaned, and when the cleaning is necessary, the user may know the cleaning time of the filter externally. Audible display.

이상에서 설명한 바와 같이 실내의 공기오염정도에 대응하여 운전누적시간의 누적비율을 증가시킴으로써 기준시간이 일정하게 고정되어 있더라도 공기의 오염정도가 낮은 지역보다 공기의 오염정도가 높은 지역에서 더 짧은 시간 안에 필터를 청소하도록 사용자에게 청소시기를 표시하게 되므로 공기오염도에 따른 필터의 청소시기판단의 오차를 보정할 수 있다.As explained above, even if the reference time is fixed by increasing the cumulative ratio of the cumulative operation time corresponding to the indoor air pollution level, in the shorter time in the area where the air pollution level is higher than the area where the air pollution level is low. Since the cleaning time is displayed to the user to clean the filter, it is possible to correct an error in determining the cleaning time according to the air pollution degree.

따라서, 필터의 청소필요여부를 정확하고 효율적으로 판단하게 되므로 냉난방 효율의 저하 및 필터에 부착된 먼지 및 부유균에 의한 세균번식으로 실내공기가 오염되는 것을 방지하여 쾌적한 공조환경을 제공할 수 있게 된다.Therefore, it is possible to accurately and efficiently determine whether the filter needs to be cleaned, thereby providing a comfortable air-conditioning environment by preventing air pollution from being contaminated by deterioration of air-conditioning efficiency and bacteria propagation by dust and floating bacteria attached to the filter. .
