도 1은 종래 기술에 따른 공기조화기의 정면도이고, 도 2는 도 1에 따른 공기조화기의 일부분이 절개된 측면도이다.1 is a front view of an air conditioner according to the prior art, and FIG. 2 is a side view of a portion of the air conditioner according to FIG. 1 cut away.

도 1 또는 도 2에 도시된 바와 같이 종래 기술에 따른 공기조화기는 상하 방향으로 길게 형성된 캐비닛(10)과, 상기 캐비닛(10)의 전면 하측에 개폐 가능하도록 설치되어 실내공기를 상기 캐비닛(10) 내부로 유입시키는 흡입그릴(11)과, 상기 흡입그릴(11)을 통해 상기 캐비닛(10) 내로 유입된 공기를 다시 실내에 골고루 분포시킬 수 있도록 상하 좌우로 조절이 가능한 풍향조절장치(12)와, 상기 흡입그릴(11)과 풍향조절장치(12) 사이에 설치되어 공기조화기의 각종 데이터를 사용자에게 알려주는 표시창(13)으로 그 외곽이 이루어진다.As shown in FIG. 1 or FIG. 2, the air conditioner according to the related art is installed to be opened and closed at a lower side of the front surface of the cabinet 10 and the cabinet 10 which is elongated in the vertical direction, and the indoor air is installed in the cabinet 10. Intake grill 11 to be introduced into the inside, and the wind direction control device 12 is adjustable up and down and left and right so that the air introduced into the cabinet 10 through the suction grill 11 can be evenly distributed again in the room; It is installed between the suction grill 11 and the wind direction control device 12, the outer surface is made of a display window 13 for informing the user of various data of the air conditioner.

그리고, 상기 캐비닛(10) 내부에 설치되어 상기 흡입그릴(11)과 풍향조절장치(12)를 통해 실내공기를 강제 유입 및 배출시키는 송풍장치(15)와, 상기 송풍장치(15)에 의해 유입된 실내공기에 함유된 먼지 등의 불순물을 포집하도록 상기 흡입그릴(11)의 후방에 장착된 필터(16)와, 상기 송풍장치(15)의 하측에 설치되어 상기 필터(16)를 통과한 실내공기를 열교환시키는 열교환기(17)로 그 내부가 구성된다.In addition, a blower (15) installed inside the cabinet (10) forcibly introducing and discharging indoor air through the suction grill (11) and the wind direction control device (12), and inlet by the blower (15). A filter 16 mounted at the rear of the suction grill 11 and a lower side of the blower 15 to collect impurities such as dust contained in the indoor air, which has passed through the filter 16. The inside is comprised by the heat exchanger 17 which heat-exchanges air.

여기서, 상기 필터(16)는 다수개의 미세한 구멍이 형성된 부직포 등으로 이루어져 공기중의 불순물을 포집하지만 완전히 포집하지 못하고, 이 불순물을 함유한 공기는 상기 열교환기(17)를 통과하면서 상기 열교환기(17)의 표면에 쌓이게 되어 그 기능을 저하시킨다.Here, the filter 16 is composed of a nonwoven fabric having a plurality of fine holes, and collects impurities in the air, but does not completely collect the air, and the air containing the impurities passes through the heat exchanger 17 while passing through the heat exchanger 17. It accumulates on the surface of 17) and reduces its function.

그러므로, 상기한 바와 같은 종래 기술의 공기조화기는 상기 필터(16)에서 포집되지 않아 상기 열교환기(17)에 쌓인 먼지 등의 불순물을 청소하기 위해서 상기 흡입그릴(11)을 탈거하여 직접 육안으로 확인해야 하는 번거로움이 있고, 이 번거로움 때문에 상기 열교환기(17)의 적정한 청소시기를 지나쳐 공기조화기의 비효율적인 운전을 수행하게 되는 문제점이 있다.Therefore, the air conditioner according to the related art as described above is not collected by the filter 16, and the suction grill 11 is removed and directly visually confirmed to clean impurities such as dust accumulated in the heat exchanger 17. There is a hassle to be done, and because of this hassle, there is a problem that an inefficient operation of the air conditioner is performed after an appropriate cleaning time of the heat exchanger 17.

The holder 54 is bent in shape and has a length shorter than that of the light emitting part 61 and the light receiving part 62, and the holder 54 is mounted to the refrigerant pipe 52 of the heat exchanger 50. 54 is formed of a fixing piece 55 in which a hole 55a is partially opened at one side end.

한편, 상기 알림수단(57)은 상기 표시창(13)을 통하여 시각적 신호인 문자 또는 아이콘(icon) 및 청각적 신호인 버저(buzzer) 등의 공지의 알림수단이 사용될 수 있다.In the meantime, the notification means 57 may use a known notification means such as a text or icon as a visual signal and a buzzer as an audio signal through the display window 13.

상기와 같이 구성된 본 발명에 따른 공기조화기의 열교환기 청소시기 알림장치는 다음과 같이 작동된다.The heat exchanger cleaning time notification device of the air conditioner according to the present invention configured as described above is operated as follows.

우선, 전원이 인가되어 공기조화기의 운전이 개시되면 송풍장치(15)에 의해 실내공기가 흡입그릴(11)을 통해 캐비닛(10) 내로 강제 유입되어 필터(16) 및 열교환기(50)를 통과한 후 풍향조절장치(12)를 통해 다시 실내로 강제 배출된다.First, when power is supplied and operation of the air conditioner is started, the indoor air is forced into the cabinet 10 through the suction grill 11 by the blower 15 to filter the filter 16 and the heat exchanger 50. After passing through the wind direction control device 12 is forcibly discharged back to the room.

여기서, 필터(16)를 통과하여도 포집되지 않은 불순물은 상기한 바와 같은 과정을 연속적으로 수행하며 서서히 열교환기(50)의 표면에 쌓이게 된다.Here, the impurities not collected even though passing through the filter 16 are continuously accumulated as described above and gradually accumulated on the surface of the heat exchanger 50.

이때, 발광부(61)는 빛을 발산하고, 수광부(62)는 발광부(61)에서 발산되어 열교환기(50)를 통과한 빛의 양을 감지하고, 제어부(56)는 빛의 양에 따라 열교환기(50)에 쌓인 불순물의 양을 감지하여 알림수단(57)으로 신호를 송출한다.At this time, the light emitting unit 61 emits light, the light receiving unit 62 emits light from the light emitting unit 61 senses the amount of light passing through the heat exchanger 50, the control unit 56 to the amount of light Accordingly, the amount of impurities accumulated in the heat exchanger 50 is detected, and a signal is sent to the notifying means 57.

그리고, 알림수단(57)은 사용자가 열교환기(50)의 청소시기를 인지할 수 있도록 외부로 신호를 표출한다.Then, the notification means 57 expresses a signal to the outside so that the user can recognize the cleaning time of the heat exchanger (50).

상기한 작동으로 인하여 사용자는 열교환기(50)의 적정한 청소시기를 놓치게 되어 공기조화기가 비효율적인 운전을 수행함을 방지할 수 있다.Due to the above operation, the user misses an appropriate cleaning time of the heat exchanger 50, thereby preventing the air conditioner from performing an inefficient operation.

상기와 같이 구성되고 동작되는 본 발명에 따른 공기조화기의 열교환기 청소시기 알림장치는 열교환기에 쌓인 불순물의 양을 감지하여 설정치 이상이면 사용자가 인지할 수 있도록 알려줌으로서, 적정한 열교환기의 청소시기를 보다 용이하게 알 수 있는 이점이 있다.The heat exchanger cleaning time notification device of the air conditioner according to the present invention configured and operated as described above detects the amount of impurities accumulated in the heat exchanger and informs the user to recognize when the setting value is higher than the set value. There is an advantage that can be seen more easily.

부가적으로, 사용자가 열교환기 청소시기 알림장치의 지시에 따라 적정시기에 열교환기의 청소를 실시하게 되면, 보다 효율적으로 공기조화기가 운전되는 이점도 있다.In addition, if the user cleans the heat exchanger at an appropriate time according to the instruction of the heat exchanger cleaning time notification device, there is an advantage that the air conditioner is operated more efficiently.
