그러나, 이러한 종래의 속도조절장치는 송풍모터의 속도조절단계에 제한되어 있어 사용자의 다양한 취향에 부응하지 못하는 단점이 있으며, 상기 저항기는 차량전장에 설치하고, 이 저항기의 저항과 접속되는 단자와 선택스위치가 형성된 스위치는 공조패널에 설치한 다음, 저항기와 스위치를 여러 가닥의 전선으로 연결하여야만 하므로, 그 구조 및 설치가 어렵고 복잡한 단점이 있다.However, such a conventional speed regulating device has a disadvantage in that it is limited to the speed adjusting step of the blower motor, thereby failing to meet various tastes of the user.

이하, 본 발명 송풍모터 속도조절장치의 바람직한 실시예를 첨부도면을 참조하에 상세하게 설명한다.Hereinafter, a preferred embodiment of the blower motor speed control device of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면중 도 2는 본 발명 송풍모터 속도조절장치의 구성도이고, 도 3a 내지 3c는 본 발명 송풍모터 속도조절장치에 적용되는 저항의 다양한 실시예를 나타낸 회로구성도이다.2 is a configuration diagram of the blower motor speed control device of the present invention, Figure 3a to 3c is a circuit diagram showing various embodiments of the resistance applied to the blower motor speed control device of the present invention.

상기 도면에서 도시하는 바와 같이, 본 발명 송풍모터 속도조절장치는 송풍모터(11)와, 이 송풍모터(11)의 전원입력라인에 설치되는 저항(12)과, 상기 저항(12)에 접촉하여 전원을 공급하는 브러쉬(13a)가 상기 저항(12)상에서 슬라이딩하게 하는 액츄에이터(13)와, 상기 액츄에이터(13)를 제어하기 위한 콘트롤스위치(14)로 구성된다.As shown in the figure, the blower motor speed control device of the present invention is in contact with the blower motor 11, the resistor 12 is installed in the power input line of the blower motor 11, the resistor 12 An electric brush 13a for supplying power is composed of an actuator 13 for sliding on the resistor 12 and a control switch 14 for controlling the actuator 13.

즉, 액츄에이터(13)에 의해 회동하는 브러쉬(13a)에 전원이 공급되고, 이 브러쉬(13a)가 송풍모터(11)의 전원입력라인상에 형성된 저항에(12) 접촉하면서 송풍모터(11)에 전원을 인가함에 따라 송풍모터(11)가 회전하게 되는데, 이때, 사용자가 원하는 송풍량을 얻기 위해 콘트롤스위치(14)를 회전시키면 이 콘트롤스위치(14)와 한가닥의 신호선(L)으로 연결된 액츄에이터(13)가 구동하면서 브러쉬(13a)를 저항상에서 이동시킴에 따라 저항값이 변하여 송풍모터(11)의 구동속도가 제어된다.That is, the power is supplied to the brush 13a which is rotated by the actuator 13, and the brush 13a is in contact with the resistance 12 formed on the power input line of the blower motor 11, and the blower motor 11 The blower motor 11 rotates as power is supplied to the actuator. At this time, when the user rotates the control switch 14 to obtain a desired blowing amount, the actuator connected to the control switch 14 and a single signal line L ( As the 13 is driven, the resistance value changes as the brush 13a is moved on the resistance to control the driving speed of the blower motor 11.

한편, 상기 저항(12)으로는 도 3a와 같은 세라믹플레이트(Seramic plate) 저항(12)이 사용되어 액츄에이터(13)에 의해 이동하는 브러쉬(13a)가 세라믹플레이트 저항(12)상에서 접촉/슬라이딩하면 송풍모터(11)로 공급되는 전원의 저항값이 가변하게 된다.On the other hand, a ceramic plate resistor 12 as shown in FIG. 3A is used as the resistor 12 so that when the brush 13a moving by the actuator 13 contacts / slides on the ceramic plate resistor 12. The resistance value of the power supplied to the blower motor 11 is varied.

또한, 도 3b는 상기 세라믹플레이트 저항(12)상을 접촉하는 브러쉬(13a)와 세라믹플레이트 저항(12)과의 접촉마찰을 줄이기 위하여 접촉단자(12a)를 세라믹플레이트 저항(12)상으로부터 일정간격 이격되게 인출시켜 형성한 것으로, 상기 액츄에이터(13)에의해 이동하는 브러쉬(13a)가 이 단자(12)를 접촉하게 하는 것이다. 여기서, 상기의 접촉단자(12)를 촘촘하게 형성한다면 송풍모터(11)의 구동속도를 무단계로 제어하는 것과 같은 효과를 얻을 수도 있을 것이다.In addition, FIG. 3B shows that the contact terminal 12a is spaced apart from the ceramic plate resistor 12 to reduce contact friction between the ceramic plate resistor 12 and the brush 13a contacting the ceramic plate resistor 12. It is formed by drawing it apart from each other, so that the brush 13a moving by the actuator 13 comes into contact with the terminal 12. Here, if the contact terminal 12 is formed densely, the same effect as controlling the driving speed of the blower motor 11 steplessly may be obtained.

또한, 도 3c는 저항으로 가변저항(12)을 사용한 것으로, 이 가변저항(12)의 원판상에 트랙으로 형성된 단자(12a)를 액츄에이터(13)에 의해 회동하는 브러쉬(13a)가 접촉하면서 통전시킴과 아울러 송풍모터(11)로 공급되는 전원라인의 저항값을 가변시키도록 하는 것으로, 이러한 가변저항(12)의 구성은 오디오기기등의 볼륨스위치에 사용되는 등 이미 널리 공지된 사항이므로 상세한 구조설명은 생략한다.In addition, FIG. 3C shows a variable resistor 12 used as a resistor, and energized while the brush 13a, which is rotated by the actuator 13, contacts the terminal 12a formed as a track on the disc of the variable resistor 12. FIG. In addition to varying the resistance value of the power supply line supplied to the blower motor 11, the structure of the variable resistor 12 is already well known, such as used in volume switches, such as audio equipment, detailed structure Description is omitted.

따라서, 저항(12)과 액츄에이터(13)가 하나의 구성품(10)으로 이루어지므로 기존과 같이 저항과 스위치를 연결하기 위한 별도의 전선들이 필요하지 않게 되며 설치가 간단해지고 제품의 제조단가 및 부피도 줄어들게 된다.Therefore, since the resistor 12 and the actuator 13 are made of one component 10, separate wires for connecting the resistor and the switch are not required as in the conventional art, and the installation is simple and the manufacturing cost and volume of the product are also reduced. Will be reduced.

첨부도면중 도 4는 본 발명 송풍모터 속도조절장치의 또 다른실시예를 나타내는 구성도이다.Figure 4 of the accompanying drawings is a block diagram showing another embodiment of the blower motor speed control apparatus of the present invention.

상기 도면에서 도시하는 본 발명 송풍모터 속도조절장치는 송풍모터(11)와, 이 송풍모터(11)의 전원입력라인에 설치되는 다수의 저항(12)과, 상기 다수의 저항(12)과 각각 연결되는 단자(12a)들이 조합되어 트랙을 갖는 패턴(P)과, 상기 패턴(P)의 단자(12a)들을 접촉하는 브러쉬(13a)가 상기 단자(12a)상에서 슬라이딩하게 하는 액츄에이터(13)와, 상기 액츄에이터(13)를 제어하기 위한 콘트롤스위치(14)로 구성된다.In the present invention, the blower motor speed control apparatus shown in the drawing includes a blower motor 11, a plurality of resistors 12 installed at a power input line of the blower motor 11, and the plurality of resistors 12, respectively. The actuator 13 which allows the connected terminal 12a to be combined to have a pattern P having a track, and a brush 13a which contacts the terminals 12a of the pattern P to slide on the terminal 12a. And a control switch 14 for controlling the actuator 13.

즉, 액츄에이터(13)에 의해 회동하는 브러쉬(13a)에 전원이 공급되고, 이 브러쉬(13a)가 송풍모터(11)의 전원입력라인상에 직렬배치된 다수의 저항(12)과 각각 연결되는 단자(12a)에 접촉하면서 송풍모터(11)에 전원을 인가함에 따라 송풍모터(11)가 회전하게 된다. 이때, 브러쉬(13a)가 접촉하는 단자(12a)를 통해 입력되는 전원이 몇개의 저항(12)을 통과하느냐에 따라서 송풍모터(11)로 공급되는 전류량이 변동되어 송풍모터(11)의 구동속도를 제어할 수 있게 된다.That is, power is supplied to the brush 13a that is rotated by the actuator 13, and the brush 13a is connected to a plurality of resistors 12 arranged in series on the power input line of the blower motor 11, respectively. The blower motor 11 is rotated by applying power to the blower motor 11 while contacting the terminal 12a. At this time, the amount of current supplied to the blower motor 11 is varied depending on how many resistors 12 the power inputted through the terminal 12a that the brush 13a contacts is passed, thereby increasing the driving speed of the blower motor 11. You can control it.

또한, 상기 브러쉬(13a)를 이동시키는 액츄에이터(13)는 전기신호를 입력받아 기계적인 변위값으로 출력하는 것으로, 이 액츄에이터(13)에 전기신호를 전달하기 위한 한가닥의 신호선(L)으로 연결된 콘트롤스위치(14)를 사용자가 조절함에 따라 액츄에이터(13)가 구동하여 브러쉬(13a)를 이동시키는 것이다.In addition, the actuator 13 for moving the brush 13a receives an electric signal and outputs it as a mechanical displacement value, and is connected to a single signal line L for transmitting an electric signal to the actuator 13. As the user adjusts the switch 14, the actuator 13 is driven to move the brush 13a.

한편, 상기 저항(12)의 갯수에 따라 송풍모터(11)의 구동속도 조절단수가 정해지게 되므로, 이러한 저항(12)의 갯수를 증가시키게 되면 무단제어와 같은 효과를 얻을 수 있게 된다.On the other hand, since the driving speed adjusting stage of the blower motor 11 is determined according to the number of the resistors 12, increasing the number of such resistors 12 can achieve the same effect as stepless control.

상기와 같은 실시예들에서 설명한 바와 같이, 본 발명 송풍모터 속도조절장치는 공조패널에 형성되는 콘트롤스위치(14)를 사용자가 조절함에 따라 한가닥의 신호선(L)으로 연결되어 구동하는 액츄에이터(13)에 의해 브러쉬(13a)가 이동하면서 저항(12) 또는 저항의 단자(12a)와 접촉하게 되는데, 이 저항(12) 및 저항의 단자(12a)와의 접촉위치에 따라 저항값이 변동하여 송풍모터(11)의 구동속도를 제어하는 것이다.As described in the above embodiments, the present invention blower motor speed control device is an actuator 13 is connected and driven by a single signal line (L) as the user adjusts the control switch 14 formed in the air conditioning panel As the brush 13a moves, the brush 12a comes into contact with the resistor 12 or the terminal 12a of the resistor, and the resistance value varies depending on the contact position between the resistor 12 and the terminal 12a of the resistor. 11) to control the driving speed.

상기한 바와 같은 본 발명 송풍모터 속도조절장치는 송풍모터의 전원입력라인에 형성되는 저항과, 상기 저항에 접촉되는 브러쉬를 형성한 액츄에이터를 하나의 구성품으로 만들어 차량전장에 설치하고, 이 액츄에이터를 구동시키기 위한 콘트롤스위치를 차량실내의 공조패널에 설치하며, 상기 액츄에이터와 콘트롤스위치를 하나의 신호선으로 연결함으로써 제품의 구성을 간소화 시키는 장점이 있다.In the present invention, the blower motor speed adjusting device includes a resistor formed in a power input line of the blower motor and an actuator having a brush in contact with the resistor as a component, installed in a vehicle electric field, and driving the actuator. In order to install the control switch to the air conditioning panel in the vehicle cabin, there is an advantage to simplify the configuration of the product by connecting the actuator and the control switch with a single signal line.
