Description

공기조화기의 토출구개폐장치Discharge port switchgear of air conditioner

본 고안은 공기조화기의 토출구 개폐장치에 관한 것으로서, 더욱 상세하게는 증발기에서 열교환된 찬 바람이 실내로 토출되는 토출구를 개폐함으로서, 사용하지 않을때 먼지가 내부로 유입되어 증발기 등이 오염되지 않도록 한 공기조화기의 토출구개폐장치에 관한 것이다.The present invention relates to a discharge opening and closing device of the air conditioner, and more particularly, by opening and closing the discharge port is discharged into the room cold air heat exchanged in the evaporator, so that dust is not introduced into the interior when not in use to contaminate the evaporator, etc. A discharge opening and closing device of an air conditioner.

일반적으로 공기조화기는 증발기 등이 설치된 실내기와 응축기 및 압축기 등이 설치된 실외기로 분리 제작된다.In general, an air conditioner is manufactured separately from an indoor unit equipped with an evaporator and an outdoor unit installed with a condenser and a compressor.

이와 같은 공기조화기의 실내기는 도 1에 도시된 바와 같이, 직사각형의 단면으로 된 실내기 본체(1)와, 그 내측 상부에 모터(8)에 의해 회전되는 순환팬(4)이 설치되고 이의 직하부에 증발기(5)가 마련된다.As shown in FIG. 1, the indoor unit of such an air conditioner is provided with an indoor unit body 1 having a rectangular cross section and a circulation fan 4 rotated by a motor 8 at an upper portion thereof. The evaporator 5 is provided at the bottom.

상기 증발기(5)는 기체액체 혼합냉매가 그 내부에 흐르는 것으로서, 상기 냉매중 액체냉매가 증발되는 과정에서 주위의 열을 흡수하여 실내온도는 내려가고 냉매 자체는 고온으로 되는 열교환과정을 수행하는 것이다.The evaporator (5) is a gas liquid mixed refrigerant flows therein, and absorbs the surrounding heat in the process of evaporating the liquid refrigerant of the refrigerant to perform a heat exchange process that the room temperature is lowered and the refrigerant itself is a high temperature .

또한, 상기 증발기(5)의 수직하부에 물받이(6)가 마련되고, 상기 실내기 본체(1)의 하단에 실내공기를 흡입하는 흡입구(3) 및 필터(7)가 형성되며, 본체(1) 상단에 순환팬(4)의 전방으로 토출구(2)가 형성되어서 흡입구(3)를 통하여 흡입된공기가 증발기(5)를 거쳐 냉각된 후 토출구(2)를 통하여 실내로 토출되도록 구성된다.In addition, the drip tray 6 is provided in the vertical lower portion of the evaporator 5, a suction port 3 and a filter 7 for suctioning the indoor air at the lower end of the indoor unit main body 1 is formed, the main body 1 The discharge port 2 is formed in front of the circulation fan 4 at the upper end so that the air sucked through the suction port 3 is cooled through the evaporator 5 and then discharged into the room through the discharge port 2.

이처럼 구성된 종래 공기조화기의 실내기는 전원이 인가되어 모터(8)에 동력이 발생되면, 이 동력을 전달받아 순환팬(4)이 회전되고 따라서, 실내공기가 흡입구(3)를 따라 실내기본체(1) 내부로 유입된다.When the indoor unit of the conventional air conditioner configured as described above is powered and power is generated in the motor 8, the circulation fan 4 is rotated by receiving this power, so that the indoor air is located along the inlet 3. 1) It is introduced inside.

이때, 흡입구(3) 후방의 필터(7)를 통해 먼지등이 걸러진 후, 증발기(3)를 거치면서 실내공기가 냉각된다. 즉, 상기 증발기(5)의 내부에는 저온저압의 냉매가 흐르는 것으로서, 도시되지 않은 실외기의 응축기에서 저온저압으로 액화되어 응축된 냉매가 모세관(미도시)을 거치면서 팽창되어 기체액체 혼합상태의 냉매로 실내기 본체(1)의 증발기(5) 쪽으로 순환되면, 이중 액체상태의 냉매가 증발하여 주위의 열을 흡수하게 되는 것이다.At this time, after the dust is filtered through the filter 7 behind the suction port 3, the indoor air is cooled while passing through the evaporator (3). That is, the low-temperature low-pressure refrigerant flows inside the evaporator 5, and the refrigerant condensed at low temperature and low pressure in a condenser of an outdoor unit (not shown) is expanded while passing through a capillary tube (not shown) to form a refrigerant in a gas liquid mixed state. When the furnace circulates toward the evaporator 5 of the indoor unit main body 1, the refrigerant in the double liquid state evaporates and absorbs the surrounding heat.

따라서, 이와 같이 냉각된 공기가 토출구(2)를 거쳐 실내로 토출됨으로서 실내가 시원하게 냉방되는 것이다.Therefore, the air cooled in this way is discharged into the room through the discharge port 2, thereby cooling the room coolly.

한편, 증발기(5) 하단의 물받이(6)는 상기 증발기(5)의 열교환과정에서 발생되는 응축수를 저장하여 외부로 배출한다.On the other hand, the drip tray 6 at the bottom of the evaporator 5 stores the condensed water generated during the heat exchange process of the evaporator 5 and discharges it to the outside.

그러나 종래의 실내기는 사용유무에 관계없이 토출구가 개방된 상태를 유지함으로 특히 실내기를 사용하지 않을때 토출구를 따라 실내 먼지가 실내기본체 내부로 유입됨으로서 이의 직 후방에 설치된 증발기 표면에 누적되어 기기의 수명이 단축되고, 아울러 상기 먼지가 다시 실내로 토출되어 실내공기가 오염되는 문제점이 있었다.However, the conventional indoor unit keeps the discharge port open regardless of whether it is used or not, and especially when the indoor unit is not used, indoor dust flows into the interior of the main body along the discharge port, and accumulates on the surface of the evaporator installed directly behind it, thereby extending the life of the device. This shortened, and the dust is discharged back to the room there was a problem that the indoor air is polluted.

또한, 먼지가 증발기 표면에 쌓인 상태로 실내기를 사용하면 이들 먼지가 단열층을 형성함에 따라 열교환 효율이 저하된다. 즉 실내공기가 증발기 표면과 직접 접촉되어 열교환이 일어나는 반면에 증발기 표면에 먼지가 쌓이면 먼지로 인하여 실내공기와 증발기 표면 사이가 차단됨으로 열교환성이 저하되는 다른 문제점도 있었다.In addition, if the indoor unit is used with dust accumulated on the surface of the evaporator, the heat exchange efficiency is lowered as these dusts form an insulating layer. That is, while heat exchange occurs because the indoor air is in direct contact with the surface of the evaporator, when dust accumulates on the surface of the evaporator, there is another problem that the heat exchangeability is lowered because the dust is blocked between the indoor air and the evaporator surface.

본 고안은 상기와 같은 문제점을 감안하여 창출한 것으로서, 그 목적은 실내기를 사용하지 않을때 토출구가 폐쇄되도록 함으로서, 실내먼지의 내부 유입을 차단하고 특히 증발기 표면에 먼지가 쌓여 열교환에 지장을 초래하지 않도록 한 공기조화기의 토출구 개폐장치를 제공함에 있다.The present invention was created in view of the above problems, and its purpose is to close the discharge port when the indoor unit is not in use, thereby blocking the inflow of indoor dust and preventing dust from accumulating on the surface of the evaporator. It is to provide a discharge opening and closing device of the air conditioner.

And it is installed on the inner top of the indoor unit main body is characterized in that it is provided with an opening and closing means for opening and closing the discharge port.

이하 본 고안의 바람직한 일실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 고안의 일실시예를 도시한 공기조화기의 측단면도이고, 도 3은 본 고안 공기조화기의 토출구개폐장치의 정단면도이다.Figure 2 is a side cross-sectional view of an air conditioner showing an embodiment of the present invention, Figure 3 is a front sectional view of the discharge opening and closing device of the air conditioner of the present invention.

본 고안의 공기조화기는 토출구(11)와 그 후방의 수직방향편(11a) 및 흡입구(12)가 상하부에 각각 형성된 직육면체의 실내기본체(10)가 구비되고 실내기본체(10) 내부의 토출구(11) 쪽의 하단에 모터(14)로 회전되는 순환팬(13)이 설치된다.The air conditioner according to the present invention is provided with an indoor main body 10 of a rectangular parallelepiped having a discharge port 11, a vertical piece 11a and a suction port 12 at the rear thereof, respectively, and a discharge port 11 inside the indoor main body 10. At the bottom of the side side, a circulation fan 13 which is rotated by the motor 14 is installed.

또한, 상기 순환팬(13) 하단에 증발기(15)가 설치되어 실내기본체(10) 내부의 흡입구(12)로 흡입된 실내공기가 열교환되어 냉각된 다음 토출구(11)를 따라 실내로 토출된다.In addition, the evaporator 15 is installed at the lower end of the circulation fan 13 so that the indoor air sucked into the suction port 12 inside the indoor main body 10 is cooled by heat exchange and then discharged into the room along the discharge port 11.

그리고, 본체(10) 상단의 토출구(11)를 개폐하는 개폐수단(20)이 상기 토출구(11) 후방에 마련된다. 상기 개폐수단(20)은 토출구(11)를 사용하지 않을 때에는 폐쇄하는 것으로서, 정역회전 되는 모터(21)에 의해 회전되면서 토출구(11)를 개폐한다.Then, the opening and closing means 20 for opening and closing the discharge port 11 of the upper end of the main body 10 is provided behind the discharge port (11). The opening and closing means 20 is closed when not using the discharge port 11 and opens and closes the discharge port 11 while being rotated by the motor 21 which is rotated forward and backward.

상기 개폐수단(20)은 토출구(11) 후방에 형성되고 좌우로 힌지핀(24)이 돌출되어 토출구(11)와 대응되는 판형으로 구성된 커버(25)가 마련되고, 상기 토출구(11)의 상단 후방에는 상기 힌지핀(24)과 대응되어 체결되도록 각각 힌지공(24a)이 형성된다.The opening and closing means 20 is formed at the rear of the discharge port 11 and the hinge pin 24 protrudes from side to side to provide a cover 25 having a plate shape corresponding to the discharge hole 11, and an upper end of the discharge hole 11. Hinge holes 24a are formed at the rear to correspond to the hinge pins 24, respectively.

또한, 커버(25) 일측의 힌지핀(24) 외주면에 기어(23)가 형성되고 기어(23)와 치합되는 구동기어(22)가 모터(21)에 의해 회전되도록 구성된다.In addition, a gear 23 is formed on the outer circumferential surface of the hinge pin 24 on one side of the cover 25, and the driving gear 22 engaged with the gear 23 is rotated by the motor 21.

한편, 커버(25)가 전후방으로 이동할 때에 접촉되는 본체(10) 내측에 각각 감지센서(26a)(26b)를 설치하여 커버(25)의 개폐동작을 제어토록 구성된다.On the other hand, it is configured to control the opening and closing operation of the cover 25 by installing the detection sensors 26a and 26b inside the main body 10 which are in contact when the cover 25 moves forward and backward.

상기와 같이 구성된 본 고안의 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the subject innovation configured as described above in detail.

공기조화기를 사용하지 않는 상태에는 도 2에 도시된 바와 같이 커버가 토출구 후방을 폐쇄하고 있다. 이후, 냉방이 시작되면 모터(21)의 구동으로 구동기어(22)가 회전되고, 이와 치합된 기어(23)를 통하여 커버(25)가 힌지핀(24)을 중심으로 상기 토출구(11)의 후방쪽으로 회전되어 토출구(11)가 개방된다.In a state where no air conditioner is used, the cover closes the rear of the discharge port as shown in FIG. 2. Subsequently, when cooling starts, the driving gear 22 is rotated by the driving of the motor 21, and the cover 25 of the discharge port 11 is centered around the hinge pin 24 through the gear 23 engaged with the driving gear 22. The discharge port 11 is opened by rotating backward.

따라서, 상기 토출구(11)가 개방됨에 따라 실내기 본체(10)가 사용가능한 상태로 되어, 모터(14)에 의해 순환팬(13)이 회전되고 실내공기가 흡입구(12)를 따라 내부로 유입된 다음 증발기(15)를 거친다.Accordingly, as the discharge port 11 is opened, the indoor unit main body 10 becomes usable, and the circulation fan 13 is rotated by the motor 14 and the indoor air is introduced into the interior of the suction port 12. The evaporator 15 is then passed through.

그리고 증발기(15)를 통과하는 과정에서 실내의 더운공기와 증발기(15) 내부의 저온의 냉매가 열교환되어 실내공기는 냉각되고 냉매는 고온으로 변환된다.In the process of passing through the evaporator 15, the indoor hot air and the low temperature refrigerant inside the evaporator 15 exchange heat, and the indoor air is cooled and the refrigerant is converted to high temperature.

따라서, 냉각된 냉기는 개방된 토출구(11)를 따라 실내로 토출되면서 실내가 시원하게 냉방되는 것이다.Therefore, the cooled cold air is discharged into the room along the open discharge port 11 to cool the room.

이후, 냉방동작을 정지시키면 모터(21)의 구동으로 구동기어(22) 및 기어(23)가 회전되어 커버(25)가 힌지핀(24)을 중심으로 토출구(11) 방향으로 회전된다.Thereafter, when the cooling operation is stopped, the drive gear 22 and the gear 23 are rotated by the driving of the motor 21, so that the cover 25 is rotated in the direction of the discharge port 11 about the hinge pin 24.

따라서, 커버(25)에 의해 토출구(11)가 폐쇄상태로 놓이게 됨으로서 실내기본체(10)를 사용하지 않을 경우, 먼지 등이 토출구(11)를 통하여 내부로 유입되지 않으므로 증발기(15) 표면에 먼지가 쌓이지 않는다.Accordingly, when the discharge opening 11 is placed in the closed state by the cover 25, when the indoor main body 10 is not used, dust or the like is not introduced into the opening through the discharge opening 11. Do not pile up.

토출구(11) 후방에 형성된 미설명 부호 11a는 수직방향편으로서 토출되는 냉각공기의 토출방향을 좌우측으로 전환시킨다.Reference numeral 11a formed at the rear of the discharge port 11 switches the discharge direction of the cooling air discharged as a vertical piece to the left and right.

본 고안은 상기 일실시예에서 설명된 내용에 국한하지 않으며, 본 고안의 사상과 원리에 벗어남이 없이 실용신안등록청구의범위에 기재된 내용에 포함되는 모든 수정, 변형 및 개량을 이에 포함하고자 한다.The present invention is not limited to the contents described in the embodiment, it is intended to include all modifications, variations and improvements included in the contents of the utility model registration claims without departing from the spirit and principles of the present invention.

본 고안은 증발기에서 열교환된 찬 바람이 실내로 토출되는 토출구를 개폐함으로서, 사용하지 않을때 먼지가 내부로 유입되어 증발기 등이 오염되지 않도록 한 효과가 있다.The present invention opens and closes a discharge port through which cold wind heat-exchanged in an evaporator is discharged into a room, thereby preventing dust from being introduced into the evaporator when not in use.
