Description

공기조화장치 실내기Air Conditioner Indoor Unit

본 발명은 공기조화장치 실내기에 관한 것으로서, 특히 시로코 팬의 작동소음을 저감하고 공기정화모드시 공기집진장치의 효율을 향상할 수 있도록 한 것이다.The present invention relates to an indoor unit of an air conditioner, and in particular, to reduce the operation noise of the sirocco fan and to improve the efficiency of the air dust collector in the air purifying mode.

종래의 공기조화장치 실내기는 도 1의 (가)(나)에 도시한 바와같이 전면 하부패널(3)에 흡입그릴(2)이 형성되었고 전면 상부패널(5)에 토출그릴(4)이 형성된 캐비넷(1)과, 외부 공기가 흡입그릴(2)을 통하여 유입되고 토출그릴(4)을 통하여 배출되도록 캐비넷(1) 안에 설치된 시로코 팬(6)과, 상기 시로코 팬(6)에 의하여 캐비넷(1)으로 유입된 외부 공기를 여과하는 먼지집진장치(8)와, 상기 시로코 팬(6)에 의하여 캐비넷(1)으로 유입된 외부 공기의 온도를 저감하는 열교환기(7)로 구성되었다.In the conventional air conditioner indoor unit, the suction grill 2 is formed on the front lower panel 3 and the discharge grill 4 is formed on the front upper panel 5, as shown in FIG. The cabinet (1), the sirocco fan (6) installed in the cabinet (1) so that the outside air is introduced through the suction grill (2) and discharged through the discharge grill (4), and the cabinet by the sirocco fan (6) A dust collector 8 for filtering the outside air introduced into 1) and a heat exchanger 7 for reducing the temperature of the outside air introduced into the cabinet 1 by the sirocco fan 6.

상기 먼지집진장치(8)는 펄터 및 여과포로 형성되었다.The dust collector 8 was formed of pulp and filter cloth.

이와같이 구성된 종래의 공기조화장치 실내기는 일반적으로 실내 온도를 저감하는 냉각모드와 실내 공기를 여과하는 공기정화모드로 운전된다.The conventional air conditioner indoor unit configured as described above is generally operated in a cooling mode for reducing room temperature and an air purification mode for filtering indoor air.

상기 냉각모드는 시로코 팬(6)을 작동하면 실내 공기가 흡입그릴(2) 및 공기집진장치(8)를 통하여 캐비넷(1) 안으로 유입되고, 그와같이 캐비넷(1)으로 유입된 실내공기는 열교환기(7)를 통과되면서 자체온도가 저감된 후 전면 상부패널(5)의 토출그릴(4)을 통하여 캐비넷(1) 밖으로 유출되어 실내 온도를 일정온도로 저감한다.In the cooling mode, when the sirocco fan (6) is operated, indoor air is introduced into the cabinet (1) through the suction grill (2) and the air dust collecting device (8), and thus the indoor air introduced into the cabinet (1) is After passing through the heat exchanger 7, its own temperature is reduced and then flows out of the cabinet 1 through the discharge grill 4 of the front upper panel 5 to reduce the room temperature to a certain temperature.

그리고 상기 공기정화모드는 도 2의 (가)(나)에 도시한 바와같이 상술한 냉각모드와 동일하게 작동되며 다만 열교환기(7)는 작동되지 않고, 공기집진장치(8)에 의하여 실내공기만를 여과하는 것이다.And the air purifying mode is operated in the same manner as the cooling mode described above as shown in (a) (b) of Figure 2 except that the heat exchanger (7) does not operate, the indoor air by the air dust collecting device (8) To filter the bay.

즉 상기 공기집진장치(8)는 흡입그릴(2)을 통하여 캐비넷(1)으로 유입되는 실내공기에 함유된 먼지를 집진한 후, 토출그릴(4)를 통하여 실내로 다시 유출하므로서 실내공기를 깨끗이 여과한다.That is, the air dust collector 8 collects the dust contained in the indoor air flowing into the cabinet 1 through the suction grill 2, and then flows back to the room through the discharge grill 4 to clean the indoor air. Filtered.

그러나 상기 공기집진장치(8)의 기능은 실내공기의 유속이 낮은 경우에만 그 기능이 발휘된다.However, the function of the air dust collecting device 8 is only exerted when the flow rate of the indoor air is low.

즉 냉방모드시 풍량을 100퍼센트로 하면 공기정화모드에서는 상기 냉방모드시 풍량의 30-40퍼센트 정도의 풍량만이 요구된다.That is, if the air volume in the cooling mode is 100 percent, only 30-40 percent of the air volume is required in the air purification mode.

따라서 상기 공기집진장치(8)는 냉방모드에서는 제역활을 하지못하고(공기집진장치(8)를 통과하는 실내공기의 유속이 빠르므로) 단지 캐비넷(1)으로 유입되는 실내공기의 유동저항만을 증가시키고, 아울러서 상기 공기집진장치(8)가 없는 상태에 비교하여 시로코 팬(6)의 동일 회전수에서 상기 캐비넷(1)으로 유입되는 실내공기의 풍랑이 감소되므로 상기 시로코 팬(1)의 회전수를 높여주어야 하며, 그로인하여 시로코 팬(1)의 작동 소음이 증가되는 문제점이 있다.Therefore, the air dust collecting device 8 does not play a role in the cooling mode (since the flow rate of the indoor air passing through the air dust collecting device 8 is fast) and only increases the flow resistance of the indoor air flowing into the cabinet 1. In addition, since the airflow of the indoor air flowing into the cabinet (1) at the same rotational speed of the sirocco fan (6) is reduced compared to the state without the air dust collector (8), the rotational speed of the sirocco fan (1) To increase the, there is a problem that the operating noise of the sirocco fan (1) is increased.

또한 공기정화모드에서는 상기 공기집진장치(8)가 설치되어 있지않은 흡입그릴(2)의 일부분을 통하여 캐비넷(1)으로 유입되는 실내공기에 의하여 그 만큼 공기정화능력이 저감되는 문제점이 있었다.In addition, in the air purifying mode, there is a problem in that the air purifying capacity is reduced by the amount of indoor air introduced into the cabinet 1 through a part of the suction grill 2 in which the air dust collecting device 8 is not installed.

본 발명은 이와같은 문제점을 감안하여 공기조화장치 실내기에 있어서, 전면하단부에 흡입구를 형성하고, 전면흡입그릴 전면 또는 그 일부를 개폐하는 차단막을 구비하여, 냉방운전모드와 공기정화모드시 전면 흡입그릴의 전부 또는 일부를 개폐하도록하여 흡입구를 선택적으로 사용하도록 하므로서, 냉방운전시 흡입저항을 저감하고 공기정화운전시 흡입구만를 통하여 실내공기가 유입되도록 한 것이다.In view of the above problems, the present invention provides an air conditioner indoor unit having a suction port formed at a lower front end thereof, and including a blocking film for opening or closing the front suction grille front or a part thereof, and the front suction grille in the cooling operation mode and the air purification mode. By opening or closing all or part of the inlet to selectively use, the suction resistance is reduced during the cooling operation, and the indoor air flows through the inlet only during the air purification operation.

In the indoor air conditioner indoor unit composed of a dust collector 108 for filtering air and a heat exchanger (107) for reducing the temperature of the outside air introduced into the cabinet 101 by the sirocco fan 106,

상기 흡입그릴(102)의 일부분에 공기집진장치(107)를 설치하고, 상기 공기집진장치(107)가 설치된 부위외의 흡입그릴(102)부를 개폐할 수 있는 차단막(109')을 구비하였다.An air dust collecting device 107 is installed on a part of the suction grill 102, and a blocking film 109 ′ capable of opening and closing the suction grill 102 outside the portion where the air dust collecting device 107 is installed is provided.

이와같이 구성된 본 발명은 일반적으로 실내 온도를 저감하는 냉각모드와 실내 공기를 여과하는 공기정화모드로 운전되며, 각각의 모드를 상세히 설명하면 다음과 같다.The present invention configured as described above is generally operated in a cooling mode for reducing indoor temperature and an air purification mode for filtering indoor air, and each mode will be described in detail as follows.

상기 공기정화모드시에는 차단막(109')이 흡입그릴(102)(공기집진장치(108)가 설치되지 않은 부위)에 장착된 상태에서, 시로코 팬(106)을 작동하면 상기 차단막(109')이 장착되지 않은 흡입그릴부(102) 만을 통하여 외부 공기가 캐비넷(101)안으로 유입되고, 동시에 상기 외부 공기가 유입되는 흡입그릴(102)부에 설치된 공기집진장치(108)를 통과하면서 외부 공기 중에 함유된 먼지등이 여과된 후, 토출그릴(104)을 통하여 상기 캐비넷(101) 밖으로 유출된다.In the air purifying mode, when the sirocco fan 106 is operated while the blocking film 109 'is mounted on the suction grill 102 (a portion where the air dust collecting device 108 is not installed), the blocking film 109' is operated. The outside air flows into the cabinet 101 through only the suction grille portion 102, which is not mounted, and at the same time passes through the air dust collecting device 108 installed in the suction grille 102 portion to which the outside air flows. After the contained dust and the like are filtered out, it flows out of the cabinet 101 through the discharge grill 104.

그리고 상기 냉각모드시에는 차단막(109')을 탈거한 후 도 3의 (다)에 도시한 바와같이 시로코 팬(106)을 작동하면 캐비넷(101)으로 유입되는 대부분의 외부공기가 상기 차단막(109')이 장착되었던 흡입그릴(102)부를 통하고 동시에 공기집진장치(108)가 설치된 흡입그릴(102)부를 통하여 적은 량의 외부공기가 상기 캐비넷(101)로 유입된다.In the cooling mode, after removing the blocking film 109 'and operating the sirocco fan 106 as shown in (c) of FIG. 3, most of the external air flowing into the cabinet 101 is blocked by the blocking film 109. A small amount of external air flows into the cabinet 101 through the suction grill 102 portion at which ') is mounted and at the same time through the suction grill 102 portion where the air dust collecting device 108 is installed.

그와같이 캐비넷(101)으로 유입된 외부 공기는 열 교환기(107)를 통과되면서 자체 온도가 저감된 후 토출그릴(105)을 통하여 상기 캐비넷(101) 밖으로 유출되어 실내 온도를 일정온도로 저감한다.As such, the outside air introduced into the cabinet 101 passes through the heat exchanger 107, and then the temperature of the external air is reduced, and then flows out of the cabinet 101 through the discharge grill 105 to reduce the room temperature to a predetermined temperature. .

이상에서 살펴본 바와같이 본 발명은 냉동모드 및 공기정화모드에 따라 캐비넷으로 유입되는 실내공기의 유입부를 가변하여, 공기정화장치 실내기의 캐비넷으로 공기를 유입/유출하는 시로코 팬의 작동효율을 향상하고 그에 따라 시로코 팬의 소음을 저감할 수 있으며, 또한 공기집진장치의 여과능력을 향상할 수 있는 효과가 있다.As described above, the present invention varies the inlet of the indoor air introduced into the cabinet according to the freezing mode and the air purification mode, thereby improving the operating efficiency of the sirocco fan to inflow / outflow of air into the cabinet of the indoor unit of the air purifier.
