공조기의 팬구동모터 회전속도 조절용 저항기 결합구조{Resistor for fan motor control}Resistor coupling structure for controlling fan speed of air conditioner {Resistor for fan motor control}

본 고안은 공조기의 팬구동모터 회전속도 조절용 저항기 결합구조에 관한 것으로서, 특히 온도퓨즈의 조립이 매우 용이함은 물론 온도퓨즈가 조립된 후의 결합력이 뛰어나 외부 충격에 쉽게 분리되지 않도록 한 것이다.The present invention relates to a resistor coupling structure for controlling the rotational speed of a fan drive motor of an air conditioner, in particular, it is very easy to assemble the temperature fuse as well as excellent bonding force after the assembled temperature fuse is not easily separated from the external impact.

현재 보급운행되고 있는 각종 차량에는 실내 공기조절수단으로 냉방 또는 온방장치가 필수적으로 설치되어 있으며, 상기 냉.온방 장치를 통해 발생되는 냉.온기류는 모터를 통해 구동되는 팬을 통해 차량 실내로 강제 공급되도록 하고 있다.Currently, various vehicles that are currently in operation are essentially equipped with air conditioning or air conditioning as means for controlling indoor air, and the cooling and warm air generated through the air conditioning system is forced into a vehicle interior through a fan driven by a motor. To be supplied.

이와같은 온.냉풍기류 강제공급 방식에 있어서는 외부온도에 대비되는 차량실내온도를 최적의 상태로 유지시켜주기 위해 미풍, 약풍, 강풍 등 대체적으로 3~4단계 정도의 단계를 설정하여 운전자가 온.냉풍의 공급세기를 조절할 수 있도록 구성되어 있다.In this forced supply of hot and cold airflow, the driver usually comes in three to four stages such as a breeze, a weak wind, and a strong wind in order to maintain the optimum indoor temperature compared to the outside temperature. It is configured to control the supply strength of cold wind.

이와같이 단계별 조작이 가능하도록 하기 위해서는 온.냉풍 강제공급수단으로 설치되는 '팬' 및 상기 팬의 구동수단으로 설치되는 모터의 회전속도를 단계별 로 선택 설정해줌으로서 실현되는 것이며, 이때 모터 회전속도 조절수단으로서 저항기가 사용되고 있다.In order to enable step-by-step operation as described above, it is realized by selecting and setting step-by-step rotational speeds of a 'fan' installed as a forced supply means of hot and cold air and a motor driving means of the fan, and at this time, the motor rotational speed control means. As a resistor is used.

이러한 목적으로 사용되고 있는 저항기는 가동시 발생되는 열량 방열수단을 이루는 방열기와, 단계별 전원접속단자 및 주전원접속단자를 수용하는 베이스본체와, 방열기 내에 탑재되는 박판상의 저항 회로기판으로 대별 구성되며, 팬의 구동수단인 모터의 이상 발생으로 인한 송풍 중단상태등 불의의 상황으로 인해 저항 회로기판에 과전류가 흐르게 될 경우 모터로 공급되는 전원을 단락시켜주는 수단으로서 온도퓨즈가 저항회로기판의 단부에 스폿 용접 되어 있는 구조이다.The resistors used for this purpose are composed of a radiator which constitutes a heat radiating means generated during operation, a base body accommodating step-by-step power connection terminals and a main power connection terminal, and a thin resistance circuit board mounted in the radiator. When overcurrent flows to the resistance circuit board due to unforeseen conditions such as blown air due to abnormality of the motor, which is the driving means, the temperature fuse is spot welded to the end of the resistance circuit board. It is a structure.

그러나, 종래에는 온도퓨즈를 단순히 스폿용접 작업에 의해 저항회로기판의 단부에 연결 접속하는 것이어서 외부의 충격에 의해 쉽게 이탈되는 문제점이 발생하고 있었고, 온도퓨즈를 방열기의 상부에 노출되게 설치하는 추세에 있어서는 외부 충격에 의한 온도퓨즈의 이탈현상이 더욱 빈번히 발생하게되는 문제점이 발생하고 있었다.However, in the related art, since the temperature fuse is simply connected to the end of the resistance circuit board by spot welding, the problem is easily removed by an external impact, and the temperature fuse is exposed to the upper part of the radiator. In this case, there was a problem in that the temperature phenomena were more frequently released due to external shocks.

따라서, 상기 문제점을 해결하기 위한 본 고안은 온도퓨즈의 조립작업이 매우 용이하고, 온도퓨즈의 리드프레임을 끼움식으로 조립하므로 장착성이 향상됨은 물론 외부충격에 강해지게 되는 효과를 기대할 수 있는 공조기의 팬구동모터 회전속도 조절용 저항기 결합구조를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems is very easy to assemble the temperature fuse, the assembly of the lead frame of the temperature fuse by fitting type of the air conditioner that can be expected to improve the mounting performance and strong external shock as well. An object of the present invention is to provide a resistor coupling structure for controlling fan rotation speed.

A caulking portion is formed at the edge of the radiator so that the resistive circuit board and the fixing plate are in close contact with each other by caulking the caulking portion, and the fixing plate forms a binding portion to which one side lead frame of the temperature fuse is fitted. Any one of the connection terminals may be configured by forming a fitting terminal portion for fitting the lead frame of the other side of the temperature fuse.

본 고안에 의하면, 코킹작업으로 저항회로기판과 고정판을 방열기에 조립한 상태에서 온도퓨즈를 고정판의 전면에 형성된 결속부와 베이스본체에 설치되어있는 전원접속단자의 끼움단자부에 끼워넣어 접속시킴에 따라 온도퓨즈 설치작업이 매우 용이해져 제품의 생산성이 향상됨은 물론 온도퓨즈의 결합력이 향상되어 외부충격에 쉽게 분리되지 않도록 하는 효과를 기대할 수 있다. According to the present invention, by connecting the resistance circuit board and the fixing plate to the radiator by caulking operation, the temperature fuse is inserted into the binding terminal formed on the front surface of the fixing plate and the fitting terminal of the power connection terminal installed on the base body.
