본 발명은 내,외기전환도어에 의해 선택에 따라 내,외기 유입구를 통해 냉,난방용 내,외기를 선택적으로 도입하여 열교환기가 설치된 공기조화케이스로 송풍하는 공기조화장치용 송풍기에 관한 것으로, 특히, 내,외기전환도어와 케이스 사이의 기밀성이 개선되어 송풍손실이 적고 공기유동소음이 저감된 공기조화장치용 송풍기에 관한 것이다.The present invention relates to a blower for an air conditioner for blowing air to an air conditioning case in which a heat exchanger is installed by selectively introducing internal and external air for cooling and heating through an internal and external air inlet, according to a selection by an internal and external air conversion door. It relates to an air conditioner blower with improved airtightness between the internal and external air conversion doors and the case to reduce airflow loss and reduce airflow noise.

자동차 공기조화장치에 포함된 송풍기는 도 1 내지 3에 도시된 바와 같이 송풍실을 형성하는 송풍케이스(1)의 하부에 내장된 모터(도시되지 않음) 구동력으로 구동하는 원심팬(도시되지 않음)의 회전에 의하여 외기(外氣) 또는 내기(內氣)를 송풍케이스(1)의 내,외기유입구(1a,1b)를 통해 선택적으로 도입하여 송풍케이스(1)의 일측에 형성된 토출구(1c)를 통해 공기조화케이스(도시되지 않음)로 송풍함으로써 그 공기가 송풍되는 동안 공기조화케이스 내장된 열교환기(도시되지 않음)를 거치면서 열교환기를 순환하는 열교환매체와 열교환하여 냉각 또는 가열된 상태로 실내에 토출되도록 함으로써 자동차 실내의 냉난방이 이루어지도록 하는 송풍장치이다.The blower included in the vehicle air conditioner is a centrifugal fan (not shown) driven by a driving force of a motor (not shown) built in the lower part of the blower case 1 forming the blower chamber as shown in FIGS. 1 to 3. The discharge port 1c formed at one side of the blower case 1 by selectively introducing outside air or blown air through the inside and outside air inlets 1a and 1b of the blower case 1 by rotation of the blower case 1. Air is blown to an air conditioning case (not shown) through the air conditioning case built-in heat exchanger (not shown) while the air is blown and exchanged with a heat exchange medium circulating the heat exchanger to cool or heated the room. It is a blower for cooling and heating of the vehicle interior by being discharged to.

이와 같은 공기조화장치용 송풍기에 있어서, 도 2와 3에 나타난 바와 같이 송풍실을 형성하는 케이스(1)의 내,외기 유입구(1a,1b) 사이에는 내기 또는 외기를 도입하기 위하여 상기 내,외기 유입구(1a,1b)를 선택적으로 개방할 수 있는 내,외기전환도어(2)가 설치된다. 그리고, 내,외기전환도어(2) 둘레에는 내,외기전환도어(2) 개폐시 케이스(1)의 내면에 밀착되어 내,외기전환도어(2)와 케이스(1) 내면 사이에 생기는 틈을 밀폐시킴으로써 공기의 누설을 막을 수 있는 패킹(20)이 결합된 다.In the air conditioner blower as described above, as shown in FIGS. 2 and 3, the internal and external air is introduced between the internal and external air inlets 1a and 1b of the case 1 to form the ventilation chamber to introduce internal air or external air. Internal and external air conversion doors 2 which can selectively open the inlets 1a and 1b are provided. Then, the inner and outer air switching door (2) circumference is in close contact with the inner surface of the case (1) when the inner and outer air switching door (2) opening and closing the gap between the inner and outer air switching door (2) and the inner surface of the case (1) Sealing 20 is combined to prevent the leakage of air by sealing.

패킹(20)은 통상 고무(Rubber)와 같은 탄력소재로 제작되며, 도 4에 나타난 바와 같이 그 선단에는 대략 Y자형으로 벌어진 리브(20a.20b)가 성형된다. 이에, 내,외기전환도어(2) 개폐시 바깥쪽의 리브(20b)가 탄성 변위되면서 케이스(1) 내면에 탄력적으로 면접촉되어 내,외기전환도어(2)와 케이스(1) 내면 사이 기밀을 유지시킴으로써 원심팬에 의해 송풍되는 공기가 누설되는 것을 막을 수 있다.Packing 20 is usually made of a resilient material such as rubber (Rubber), as shown in Figure 4, the ribs (20a. 20b) is formed in the front end of the approximately Y-shaped. Therefore, when the inner and outer air switching doors 2 are opened and closed, the outer rib 20b is elastically displaced and is elastically surface-contacted to the inner surface of the case 1 so that the airtightness between the inner and outer air switching doors 2 and the inner surface of the case 1 is closed. It is possible to prevent the air blown by the centrifugal fan from leaking out.

이와 같은 패킹(20)이 포함됨에 따라 공기조화장치용 송풍기는 내,외기유입구(1a,1b)를 통해 도입된 공기를 송풍손실 없이 공기조화케이스로 송풍할 수 있다.As the packing 20 is included, the air conditioner blower may blow air introduced through the internal and external air inlets 1a and 1b to the air conditioning case without blowing a loss.

그러나, 도 4에 나타난 바와 같이 종래 공기조화장치용 송풍기는 패킹(20)의 리브(20b)가 접촉되는 케이스(1)의 내면이 평탄면으로 형성되어 리브(20b)가 케이스(1) 내면에 대해 거의 선접촉하는 형태로 접촉하기 때문에 접촉면적이 매우 작고 또한 리브(20b)가 과도하게 변형되는 단점이 있었다. 이 때문에 종래 공기조화장치용 송풍기는 내,외기전환도어(2)의 기밀성이 떨어져 송풍효율이 떨어지고 공기 누설 소음을 유발하는 문제점이 있었다. 뿐만 아니라, 과도한 변형이 반복 누적됨에 따라 패킹(20)의 피로수명이 매우 짧다는 문제점도 있었다.However, as shown in FIG. 4, in the conventional air conditioner blower, the inner surface of the case 1 to which the ribs 20b of the packing 20 are in contact is formed into a flat surface so that the ribs 20b are formed on the inner surface of the case 1. The contact area is very small since the contact is almost in line contact with the rib, and the rib 20b is excessively deformed. For this reason, the conventional air conditioner blower has a problem in that airtightness of the internal and outdoor air conversion doors 2 is lowered, thereby lowering the blowing efficiency and causing air leakage noise. In addition, there is a problem that the fatigue life of the packing 20 is very short, as excessive strain is accumulated repeatedly.

본 발명은 상술한 바와 같은 종래 공기조화장치용 송풍기의 문제점을 개선하기 위하여 안출된 것으로, 기밀 유지를 위해 내,외기전환도어의 둘레에 결합된 패킹과 케이스 내면 사이의 접촉면적은 크게 확대되는 반면, 패킹의 변위량이 대폭 감소됨으로써 내,외기전환도어의 기밀성이 크게 개선되어 송풍손실이 적고 송풍소 음은 오히려 저감된 공기조화장치용 송풍기를 제공하는데 목적이 있다.The present invention has been made to improve the problems of the conventional air conditioner blower as described above, while the contact area between the packing and the inner surface of the case coupled to the circumference of the internal and outdoor air conversion door for airtightness is greatly enlarged, As the displacement of the packing is greatly reduced, the airtightness of the internal and outdoor air conversion doors is greatly improved, so that the blower loss is reduced and the blower noise is rather reduced.

이상의 목적을 달성하기 위하여 본 발명은, 케이스에 형성된 내,외기 유입구를 통해 내,외기전환도어의 개폐 선택에 따라 내,외기를 선택적으로 도입하여 열교환기가 내장된 공기조화케이스로 송풍할 수 있게 구성된 것으로, 상기 내,외기전환도어 둘레에 상기 내,외기전환도어 개폐시 상기 케이스의 내면에 탄력적으로 밀착되면서 상기 내,외기전환도어와 케이스 사이 기밀을 유지시킬 수 있는 패킹이 결합된 공기조화장치용 송풍기에 있어서, 특히 상기 내,외기전환도어의 패킹과 맞닿는 상기 케이스의 내면에 상기 패킹의 선단부가 몰입될 수 있는 만곡부가 형성된 것을 특징으로 한다.In order to achieve the above object, the present invention, through the internal and external air inlet formed in the case is configured to blow the air conditioning case with a heat exchanger by selectively introducing the internal and external air according to the opening and closing selection of the internal and outdoor air conversion doors To, the air conditioning apparatus coupled to the packing to maintain the airtightness between the inner and outer air conversion door and the case while elastically close to the inner surface of the case when opening and closing the inner and outer air conversion door around the inner, outer air conversion door In the blower, in particular, the inner surface of the case in contact with the packing of the internal and external air conversion door is characterized in that the front end portion of the packing portion is immersed.

그리고, 상기 만곡부의 표면은 단면으로 볼 때 원호형의 곡면을 갖도록 형성된 것이 바람직하다.And, the surface of the curved portion is preferably formed to have an arc-shaped curved surface in cross section.

이상과 같은 구성으로 이루어진 본 발명에 따른 공기조화장치용 송풍기는 모터에 의해 구동되는 원심팬에 의해 송풍케이스의 내,외기유입구를 통해 외기(外氣) 또는 내기(內氣)를 선택적으로 도입하여 송풍케이스의 일측에 형성된 토출구(도시되지 않음)를 통해 공기조화케이스로 송풍할 수 있는데, 특히, 내,외기전환도어에 결합된 패킹이 케이스 내면에 형성된 만곡부에 몰입되어 넓은 면적으로 접촉하면서 변위량은 최소화됨으로써 내,외기전환도어의 기밀성이 우수하다. 따라서 송풍손실이 적어 송풍효율이 높고, 패킹의 접촉면에서 공기누설 소음이 적어 승차감 개선에 기여할 수 있으며, 패킹의 피로수명이 길다는 장점이 있다.The air conditioner blower according to the present invention having the above configuration selectively introduces external air or internal air through the internal and external air inlets of the blower case by a centrifugal fan driven by a motor. It is possible to blow into the air conditioning case through the discharge port (not shown) formed on one side of the blower case, in particular, the packing coupled to the inner and outer air switching doors is immersed in the curved portion formed on the inner surface of the case and the displacement amount is By minimizing the airtightness of the outdoor and outdoor air conversion door. Therefore, the blowing loss is low, the blowing efficiency is high, the air leakage noise is less at the contact surface of the packing can contribute to the improvement of ride comfort, and the fatigue life of the packing is long.

이하, 바람직한 실시예를 통해 본 발명의 일 실시예에 따른 공기조화장치용 송풍기의 구성과 작용을 보다 구체적으로 살펴본다.Hereinafter, a look at the configuration and operation of the air conditioner blower according to an embodiment of the present invention through a preferred embodiment in more detail.

본 발명의 일 실시예에 따른 공기조화장치용 송풍기는 도 1 내지 3에 도시된 바와 같이 송풍케이스(1)의 하부에 내장된 원심팬(도시되지 않음)의 회전에 의하여 송풍케이스(1)의 상부 양측에 형성된 내,외기유입구(1a,1b)를 통해 외기(外氣) 또는 내기(內氣)를 선택적으로 도입하여, 그 공기를 송풍케이스(1)의 일측에 형성된 토출구(1c)를 통해 공기조화케이스(미도시)로 송풍하여 공기조화케이스(도시되지 않음)에 내장된 열교환기(도시되지않음)를 거치면서 열교환기를 순환하는 열교환매체와 열교환된 후 냉각 또는 가열된 상태로 실내에 토출되도록 함으로써 자동차 실내의 냉난방이 이루어지도록 하는 송풍장치이다.The air conditioner blower according to the embodiment of the present invention by rotating the centrifugal fan (not shown) built in the lower portion of the blower case 1 as shown in Figure 1 to 3 of the blower case (1) The outside air or the inside air is selectively introduced through the inside and outside air inlets 1a and 1b formed on both sides of the upper side, and the air is discharged through the discharge port 1c formed on one side of the blower case 1. Blowing into an air conditioning case (not shown), passing through a heat exchanger (not shown) built in an air conditioning case (not shown), and heat-exchanging with a heat exchange medium circulating the heat exchanger, and then discharging it indoors while being cooled or heated. It is a blower to make the heating and cooling of the interior of the car by making it.

이와 같은 송풍기에서 송풍실을 형성하는 케이스(1)의 상부에는 도 2와 3에 나타난 바와 같이 그 양측에 형성된 내,외기 도입구(1a,1b)를 선택적으로 개방하기 위한 원통형의 내,외기전환도어(2)가 설치된다. 그리고, 내,외기전환도어(2)의 둘레에는 도 5에 도시된 바와 같이 내,외기전환도어(2) 개폐시 케이스(1)의 내면에 밀착되면서 내,외기전환도어(2)와 케이스(1) 내면 사이에 형성되는 틈을 밀폐시켜 공기의 누설을 막을 수 있는 패킹(20)이 끼워져 결합된다.Cylindrical internal and external air switching for selectively opening the internal and external air inlets 1a and 1b formed at both sides of the case 1 forming the air blast chamber in the blower as shown in FIGS. 2 and 3. The door 2 is installed. And, the inner and outer air switching door (2) as shown in Figure 5, the inner and outer air switching door (2) close and close to the inner surface of the case (1) when opening and closing the inner and outer air switching door (2) and the case ( 1) Sealing the gap formed between the inner surface to prevent the leakage of air packing 20 is fitted.

패킹(20)은 내,외기전환도어 개폐시 케이스(1) 내면에 탄력적으로 변위되어 밀착될 수 있도록 통상 고무(Rubber)와 같은 탄력소재로 제작되며, 그 선단에는 케이스(1)에 대한 접촉면적을 늘리기 위한 Y자형 리브(20a.20b)가 성형된다.The packing 20 is usually made of a resilient material such as rubber so as to be elastically displaced and adhered to the inner surface of the case 1 when the inner and outer air switching doors are opened and closed, and the contact area with respect to the case 1 at the front end thereof. The Y-shaped ribs 20a. 20b are formed to increase the width.

그리고, 송풍기 케이스(1)의 내면에는 내,외기전환도어(2) 개폐시 패킹(20)이 접촉하게 되는 부분에 패킹(20)의 리브(20b)가 몰입될 수 있는 원호형의 내주면을 형성하는 만곡부(10)가 형성된다.In addition, an inner circumferential surface of the blower case 1 is formed on an inner circumferential surface of which the rib 20b of the packing 20 can be immersed in a portion where the packing 20 is in contact with the inside and outside air conversion doors 2 when opening and closing. The curved portion 10 is formed.

만곡부(10)는 상기 패킹의 기밀성을 더욱 향상시키기 위해 형성된 것으로서, 패킹(20)의 리브(20b)가 몰입되어 변위되는 형상 그대로 내주면에 접촉하게 함으로써 리브(20b)의 케이스(1)에 대한 접촉면적을 확대시키고 패킹(20)의 리브(20b)가 과도하게 변형되는 것을 막아 준다.The curved portion 10 is formed to further improve the airtightness of the packing and is in contact with the case 1 of the rib 20b by bringing the rib 20b of the packing 20 into contact with the inner circumferential surface as it is immersed and displaced. It enlarges the area and prevents the rib 20b of the packing 20 from being excessively deformed.

도 3에서 설명되지 않은 부호 3은 공기필터이다.Reference numeral 3, which is not described in FIG. 3, is an air filter.

이상과 같이 구성의 본 발명에 따른 공기조화장치용 송풍기는 내,외기전환도어(2)의 개폐 선택에 따라 내,외기유입구(1a,1b)를 통해 내,외기(外氣)를 선택적으로 도입하여 토출구(1c)를 통해 공기조화케이스로 송풍하게 되는데, 특히, 내,외기전환도어(2)에 결합된 패킹(20)의 리브(20b)가 스(1) 내면에 형성된 만곡부(10)에 몰입되어 넓은 면적으로 접촉함에 따라 내,외기전환도어(2)의 기밀성이 우수하고, 패킹(20)의 변형율이 매우 적다는 특징이 있다.The air conditioner blower according to the present invention having the above configuration selectively introduces internal and external air through the internal and external air inlets 1a and 1b according to the selection of opening and closing of the internal and external air conversion doors 2. Air is blown through the discharge port 1c to the air conditioning case. In particular, the rib 20b of the packing 20 coupled to the inner and outer air switching doors 2 is formed on the curved portion 10 formed on the inner surface of the switch 1. As immersed in contact with a large area, the airtightness of the internal and external air conversion doors 2 is excellent, and the strain of the packing 20 is very small.

이상에서 상세히 살펴본 바와 같이, 본 발명에 따른 공기조화장치용 송풍기는 내,외기 모드전환도어의 패킹이 케이스의 만곡부에 몰입되어 변형율이 최소화된 상태에서 넓은 면적으로 케이스에 접촉함에 따라 내,외기전환도어의 기밀성이 우수하고, 패킹의 변위량이 작다.As described in detail above, the air conditioner blower according to the present invention is switched to the internal and external air as the packing of the internal and external air mode switching door is immersed in the bent portion of the case and contacts the case with a large area in a state where the strain is minimized.
