Description

와셔모터 공회전 방지장치Washer Motor Idle Prevention Device

본 발명은 자동차의 와셔모터 공회전 방지장치에 관한 것으로서, 상세하게는 와셔탱크에 레벨 스위치를 설치하여 와셔액의 수위가 떨어지면("0"상태) 스위치에 의해 릴레이가 작동하여 와셔모터의 전원 공급을 차단하게 한 와셔모터 공회전 방지장치에 관한 것이다.The present invention relates to a washer motor idle prevention device of a vehicle. Specifically, a level switch is installed in a washer tank, and when the level of the washer fluid drops ("0" state), the relay is operated by a switch to cut off the power supply of the washer motor. To a washer motor idle prevention device.

일반적으로 와셔모터라 함은 윈드 실드(운전석 윈도우)의 유리창에 세정액을 분사하여 유리면을 닦아 내기 위한 모터로서, 탱크에 저장된 세정액을 펌프로 보내 노즐에서 분사하게 되어 있다.In general, a washer motor is a motor for wiping a glass surface by spraying a cleaning liquid on a windshield (driver's seat window), and sending a cleaning liquid stored in a tank to a pump to spray the nozzle.

즉, 와셔모터는 와셔액 탱크의 세정액을 분사시키기 위한 모터로서 와이퍼를 작동시키는 주요 부품이다.That is, the washer motor is a main part for operating the wiper as a motor for injecting the washing liquid of the washer liquid tank.

대개의 경우 와셔라 함은 유리창에 세정액을 분사하는 장치를 말하는 것으로서, 유리면 전체에 균일하게 와셔액을 분사하기 위하여 분사점을 많게 하거나 부채꼴로 발산하는(확산노즐)것 이외에도 암이나 블레이드에 노즐을 설치한 것 등의 형식이 있으며, 와이퍼와 연동하여 블레이드가 작동하는 시간에 작동하게 되어 있는 것도 있다.In most cases, a washer is a device that sprays a cleaning liquid onto a glass window. In order to spray the washer liquid evenly on the entire glass surface, nozzles are installed on the arm or blade in addition to the spraying point spreading or fan-shaped (diffusion nozzle). There is a type such as one, and in conjunction with the wiper, some blades are operated at the time of operation.

종래의 와셔 탱크에 저장된 와셔모터는 세정액이 완전히 소모되어 분사할 수 있는 세정액이 없게 되어 있어도 작동되도록 구성되어 있어 와셔액이 없는 것을 모르고 계속 와셔모터를 구동하게 되면 파손될 우려가 있었다.The washer motor stored in the conventional washer tank is configured to operate even if the cleaning liquid is completely consumed and there is no cleaning liquid that can be sprayed, so that the washer fluid may be damaged if the washer motor is continuously driven without knowing that the washer liquid is not present.

즉, 종래의 와셔모터 장치는 와셔탱크의 세정액이 완전히 소모되어 분사할 세정액이 없는 상태에서도 와셔모터가 작동하게 되어 있게 됨에 따라 와셔모터에 과부하가 작용하여 와셔모터를 소손시킬 문제점이 있었다.That is, the conventional washer motor device has a problem of overloading the washer motor to burn out the washer motor as the washer motor is operated even when the washing liquid of the washer tank is completely consumed and there is no cleaning liquid to be injected.

이에, 본 발명은 상기와 같은 문제점을 해소하기 위하여 발명한 것으로서, 와셔탱크에 와셔액의 수위를 감지하는 레벨스위치를 형성하여 와셔모터를 제어하게 함으로서 와셔탱크의 세정액이 완전히 소모되었을 경우에는 와셔모터가 작동되지 않게 하는 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, by forming a level switch to sense the level of the washer fluid in the washer tank to control the washer motor, when the washer is completely consumed, the washer motor is It is an object of the present invention to provide a device for deactivation.

따라서, 본 발명은 와셔탱크에 설치되어 세정액의 완전 소모 여부에 센싱하는 레벨 스위치와 상기 레벨스위치가 와셔모터의 구동을 제어할 수 있게 하는 것을 특징으로 한다.Therefore, the present invention is characterized in that the level switch and the level switch to be installed in the washer tank to sense whether or not the cleaning liquid is completely consumed to control the driving of the washer motor.

상기한 목적을 달성하기 위한 본 발명의 구성에 대하여 예시한 도면을 참조하여 설명하면 다음과 같다.Referring to the drawings illustrating the configuration of the present invention for achieving the above object is as follows.

도 1은 본 발명에 따른 와셔탱크의 레벨 스위치를 도시한 회로도이고, 도 2는 본 발명에 따른 와셔탱크의 내부 상태를 도시한 내부 상태도이며, 도 3은 본 발명에 따른 와셔모터 공회전 방지 장치의 회로도이다.1 is a circuit diagram showing a level switch of a washer tank according to the present invention, Figure 2 is an internal state diagram showing an internal state of the washer tank according to the present invention, Figure 3 is a washer motor idle prevention device according to the present invention It is a circuit diagram.

와셔액, 즉 세정액의 수위를 감지할 수 있게 하는 레벨 스위치(10)가 와셔탱크(20)에 설치되고, 상기 레벨 스위치(10)는 세정액의 수위에 따라 이동하는 마그네틱(40)에 의해 세정이 완전 소모시에 온 레벨스위치(10)의 접지단이 마그네틱(40)과 접지함에 따라 "온" 상태가되어 릴레이(70)에 신호를 인가함으로써, 상기 릴레이(70)가 점화 전원으로부터 와셔모터(60)에 공급되는 전원을 차단할 수 있고, 와셔 레벨 경고램프를 작동시킬 수 있도록 구성된 것을 특징으로 한다.A level switch 10 is installed in the washer tank 20 to allow the washer fluid, that is, the level of the cleaning liquid, to be cleaned by the magnetic 40 moving in accordance with the level of the cleaning liquid. When the ground level of the on-level switch 10 is grounded with the magnetic 40 at the time of consumption, the state becomes "on" and a signal is applied to the relay 70, whereby the relay 70 receives a washer motor 60 from an ignition power supply. It is possible to cut off the power supplied to the, and to be configured to operate the washer level warning lamp.

또한, 이때 와셔모터(60)의 전원 차단과 함께 와셔액 레벨 경고램프(30)가 점등되도록 점화전원과 레벨 스위치(10) 사이에 직렬 연결되어 접지단자로 전류를 흘려 보낼 수 있게 구성된다.In addition, at this time, the washer fluid level warning lamp 30 is turned on together with the power off of the washer motor 60 so as to be connected in series between the ignition power supply and the level switch 10 so as to allow a current to flow to the ground terminal.

상기한 본 발명이 구성에 대한 작용 및 효과는 다음과 같다.Actions and effects on the configuration of the present invention described above are as follows.

와셔탱크(20)에 설치된 마그네틱(40)은 와셔액, 즉 세정액의 수위에 따라 이동하게 되어 있으며, 세정액이 완전 소모될 시에 레벨 스위치(10)를 "온" 상태로 하게 하는 작용을 한다.The magnetic 40 installed in the washer tank 20 moves in accordance with the washer liquid, that is, the level of the washing liquid, and serves to turn the level switch 10 on when the washing liquid is completely consumed.

또한, 제 1 도에 도시된 바와 같이, 레벨 스위치(10)가 "온" 상태가 됨에 따라 작동하는 와셔 레벨 경고램프(30)가 작동, 즉 점등하게 되어 운전자에게 세정액의 완전 소모된 상태를 알리게 하는 작용을 한다.In addition, as shown in FIG. 1, the washer level warning lamp 30, which operates as the level switch 10 is in the " on " state, is activated, i.e., lights up to inform the driver of the complete consumption of the cleaning liquid. It works.

또한, 점화전원과 와셔모터(60) 사이에 연결된 릴레이(70)는 레벨스위치(10)의 신호가 온 상태가 됨에 따라 코일에 전류가 통전되어 릴레이(70)에 형성된 스위치가 오프되어 와셔모터(60)에 공급되는 전원을 차단하게 되는 작용을 한다.In addition, in the relay 70 connected between the ignition power and the washer motor 60, as the signal of the level switch 10 is turned on, current is energized in the coil, so that the switch formed in the relay 70 is turned off and the washer motor ( 60) to cut off the power supply.

이와 같이, 본 발명을 이용한 자동차는 와셔탱크의 세정액 수위를 레벨 스위치에 의하여 체크되어 완전소모시 경고램프와 함께 와셔모터를 제어하게 함으로써, 운전자에게 램프를 통해 세정액 보충시기를 적시에 통보할 수 있게 되며 와셔모터를 보호할 수 있는 효과가 있다.As described above, the vehicle using the present invention checks the washing liquid level of the washer tank by the level switch to control the washer motor with the warning lamp when it is completely consumed, so that the driver can be notified in a timely manner when the washing liquid is replenished through the lamp. It has the effect of protecting the washer motor.
