Abstract

PURPOSE: A moving type air blower of air conditioning system for automobile is provided to improve cooling and heating performance and to reduce noise of the air blower. CONSTITUTION: A blow-fan(21) of an air blower(20) moves up and down centering around a rotary shaft(23) for inflow of outside air and inside air, respectively. The rotary shaft is telescopic type. The blow-fan is moved to an outside air inlet(30) to move noise source to a distance in such a manner that more noise is generated when outside air flows in. Loss of blast capacity due to falling of pressure on an upper part is prevented thereby to increase air volume flowing into a car room.

자동차용 에어컨 장치의 이동식 송풍팬{Blow-fan for moving of air-conditioner for automobile}Blow-fan for moving of air-conditioner for automobile

본 발명은 자동차용 에어컨 장치의 이동식 송풍팬에 관한 것으로서, 더욱 상세하게는 내기 작동시에 에어컨 장치의 하부에 위치해 있던 송풍팬이 외기 작동시에 상부에 위치한 외기 유입구쪽으로 상승함으로써, 상부에서 작동 압력 강하로 인한 상기 송풍팬의 풍량 손실을 줄여주어 실내로 유입되는 풍량이 증가됨으로써, 냉방 및 난방 성능이 향상되고, 송풍팬 작동 소음을 줄일 수 있는 자동차용 에어컨 장치의 이동식 송풍팬에 관한 것이다.The present invention relates to a mobile blower fan of an air conditioner for a vehicle, and more particularly, an operating pressure at the upper part of the blower fan, which is located at the lower part of the air conditioner at the time of betting operation, rises toward the outside air inlet located at the upper part of the outside air operation. The present invention relates to a mobile blower fan for an air conditioner for a vehicle, which reduces air flow loss due to a drop, thereby increasing the amount of air introduced into the room, thereby improving cooling and heating performance and reducing noise of the blower fan.

일반적으로, 자동차 에어컨 장치의 구성 요소중에 하나인 송풍기(20)는 도 3에 도시된 바와 같이, 송풍팬(21)과 송풍모터(22)로 구성되며, 외기 유입구(30)와 공기 토출구(50)가 형성된 에어컨 장치(10)의 하우징(11)에 일체식으로 결합된다.In general, as shown in FIG. 3, the blower 20, which is one of the components of the automotive air conditioner, includes a blower fan 21 and a blower motor 22, and an outside air inlet 30 and an air outlet 50. ) Is integrally coupled to the housing 11 of the formed air conditioner 10.

이때, 상기 송풍팬(21)은 에어컨 장치(10)의 하우징(11) 내부에 위치되도록 결합되며, 상기 송풍모터(22)는 에어컨 장치(10)의 하우징(11)의 외부에 위치되도록 결합된다.In this case, the blower fan 21 is coupled to be positioned inside the housing 11 of the air conditioner 10, and the blower motor 22 is coupled to be positioned outside the housing 11 of the air conditioner 10. .

그리고, 송풍기(20)의 작동시에 공기는 송풍팬(21)이 회전에 의하여 외기 유입구(40)나 내기 유입구(40)로부터 공기 토출구(50)로 송풍되고, 히터 코어(미도시)나 증발기 코어(60)를 통과하면서 가열하거나 냉각된 후, 자동차 실내로 공급된다.When the blower 20 is operated, air is blown from the outside air inlet 40 or the inside air inlet 40 to the air outlet 50 by the rotation of the blower fan 21, and the heater core (not shown) or the evaporator is blown. After being heated or cooled while passing through the core 60, it is supplied to the vehicle interior.

그런데, 종래의 에어컨 장치의 송풍팬이 내, 외기 작동시에 일정한 위치에 고정되어 있어 외기 작동시에는 유동에 따르는 압력 강하 및 소음 발생이 심한 문제점이 있었다.However, the blower fan of the conventional air conditioner device is fixed at a constant position during internal and external air operation, and there is a problem in that pressure drop and noise generation due to flow are severe during external air operation.

따라서, 상기와 같은 문제점을 감안하여 안출한 것으로서, 내기 작동시에 에어컨 장치의 하부에 위치해 있던 송풍팬이 외기 작동시에 상부에 위치한 외기 유입구쪽으로 상승함으로써, 상부에서 작동 압력 강하로 인한 상기 송풍팬의 풍량 손실을 줄여주어 실내로 유입되는 풍량이 증가됨으로써, 냉방 및 난방 성능이 향상되고, 송풍팬 작동 소음을 줄일 수 있는 자동차용 에어컨 장치의 이동식 송풍팬을 제공하는데 그 안출의 목적이 있다.Accordingly, in view of the above problems, the blower fan located in the lower part of the air conditioner device during the bet operation rises toward the outside air inlet port located in the upper part during the operation of the outside air, whereby the blowing fan due to the operating pressure drop in the upper portion. The purpose of the present invention is to provide a mobile blower fan for an air conditioner for a vehicle that can reduce airflow loss and increase the amount of air flowing into the room, thereby improving cooling and heating performance and reducing blower fan operation noise.

본 발명은 송풍팬(21)과 송풍모터(22)로 구성되며, 외기 유입구(30)와 내기 유입구(40) 및 공기 토출구(50)가 형성된 에어컨 장치(10)의 하우징(11)에 일체식으로 결합된 송풍기에 있어서, 상기 송풍기(20)의 송풍팬(21)은 외기 및 내기 작동시에 최전축(23)을 중심으로 각각 상승 및 하강 이동하여 작동되는 것을 특징으로 한다.The present invention comprises a blower fan 21 and a blower motor 22, and integrally formed in the housing 11 of the air conditioner 10 having the outside air inlet 30, the inside air inlet 40, and the air outlet 50. In the blower coupled to, the blower fan 21 of the blower 20 is characterized in that it is operated by moving up and down around the foremost shaft 23 during the operation of the outside air and bet.

특히, 상기 회전축(23)은 자동차용 안테나 구조와 동일한 구조인 것을 특징으로 한다.In particular, the rotating shaft 23 is characterized in that the same structure as the antenna structure for automobiles.

이하, 첨부도면을 참조하여 본 발명의 구성과 작용에 대해 상세하게 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention with reference to the accompanying drawings in detail.

도 1은 본 발명에 따른 내기 작동시, 송풍팬의 위치를 나타내기 위해 도시한단면도이고, 도 2는 본 발명에 따른 외기 작동시, 송풍팬의 위치를 나타내기 위해 도시한 단면도를 나타낸다.1 is a cross-sectional view showing the position of the blowing fan during the bet operation according to the present invention, Figure 2 is a cross-sectional view shown to show the position of the blowing fan during the operation of the outdoor air according to the present invention.

여기서, 도면 부호 20은 송풍기를 나타낸다.Here, reference numeral 20 denotes a blower.

상기 송풍기(20)는 송풍팬(21)과 송풍모터(22)로 구성되며, 외기 유입구(30)와 내기 유입구(40) 및 공기 토출구(50)가 형성된 에어컨 장치(10)의 하우징(11)에 일체식으로 결합된다.The blower 20 includes a blower fan 21 and a blower motor 22, and the housing 11 of the air conditioner 10 having the outside air inlet 30, the inside air inlet 40, and the air outlet 50 formed therein. Are integrally coupled to.

이때, 상기 송풍팬(21)은 송풍모터(22)의 회전축(23)에 결합되어 있는 한편, 에어컨 장치(10)의 하우징(11) 내부에 위치되도록 결합되며, 상기 송풍모터(22)는 상기 하우징(11)의 외부에 위치되도록 결합된다.In this case, the blower fan 21 is coupled to the rotary shaft 23 of the blower motor 22, and coupled to be positioned in the housing 11 of the air conditioner 10, and the blower motor 22 is It is coupled to be located outside the housing 11.

이때, 회전축(23)은 자동차용 안테나 구조와 동일한 구조로 되어 있어, 일반적으로 공지된 기술로 이루어진 것을 사용하는 것이 바람직하다.At this time, the rotating shaft 23 has the same structure as the antenna structure for automobiles, it is preferable to use those made of a generally known technique.

다음에는 이러한 구성을 갖는 본 발명의 작동 원리에 대해 설명하기로 한다.Next, the working principle of the present invention having such a configuration will be described.

내기 작동시에 에어컨 장치(10)의 하우징(11) 하부에 위치한 송풍팬(21)이 작동하여 실내 공기를 순환시키고, 외기 작동시에는 상기 송풍팬(21)이 회전축(23)과 동시에 상부에 위치한 외기 유입구(30)쪽으로 상승, 상기 외기 유입구(30) 바로 밑에 위치하여 외기를 실내로 유입시킨다.The blowing fan 21 located in the lower part of the housing 11 of the air conditioner 10 operates to circulate the indoor air during the betting operation, and during the outside air operation, the blowing fan 21 moves upwardly at the same time as the rotating shaft 23. Ascending toward the outside air inlet 30 is located, located directly under the outside air inlet (30) to introduce the outside air into the room.

그러면, 외부의 공기가 유입되므로 내기 작동시보다 노이즈가 많이 발생하게 되는데, 송풍팬(21)을 외기 유입구(30)로 이동시키면 상기 송풍팬(21) 작동시 발생하는 소음원을 멀리하게 되므로 소음량을 최소화 할 수 있다.Then, since the outside air is introduced, more noise is generated than during the betting operation. Moving the blower fan 21 to the outside air inlet port 30 keeps away the noise source generated when the blower fan 21 operates. Can be minimized.

다시, 내기 작동시에는 상부에 있던 상기 송풍팬(21)과 회전축(23)이 하부로이동한다.In addition, during the betting operation, the blowing fan 21 and the rotary shaft 23 which are on the upper side move to the lower side.

이때, 상기 회전축(23)은 자동차용 안테나의 구조와 동일한 구조로 되어 있어, 그 회전축(23)에 장착된 송풍팬(21)을 자동으로 상승, 또는 하강시킨다.At this time, the rotating shaft 23 has the same structure as that of the automotive antenna, and automatically raises or lowers the blowing fan 21 mounted on the rotating shaft 23.

이상에서와 같이, 본 발명은 송풍팬이 자동으로 상승, 하강 이동함에 따라 외기 작동시에 외기 유입구쪽으로 상기 송풍팬이 상승 이동하므로 상부에서 압력강하로 인한 풍량 손실을 줄여주기 때문에 자동차 실내로 유입되는 풍량이 증가하게 되어 냉방 및 난방 성능이 향상되며, 또한, 상기 송풍팬 작동시 발생하는 소음원을 멀리하게 되므로 송풍팬의 작동 소음을 줄일 수 있는 효과가 있다.As described above, according to the present invention, as the blower fan moves up and down automatically, the blower fan moves up and down toward the outside air inlet during the operation of the outside air, thereby reducing the amount of wind loss due to the pressure drop from the upper portion. Since the air volume is increased, the cooling and heating performance is improved, and the noise source generated during the operation of the blower fan is kept away, thereby reducing the operating noise of the blower fan.
