Description

모터어셈블리Motor assembly
본 발명은 임펠러의 결합구조를 개선한 모터어셈블리에 관한 것이다.The present invention relates to a motor assembly with improved coupling structure of the impeller.
일반적으로 진공청소기는 청소기 본체 내부에 장착되는 모터에 의해 발생되는 진공압을 이용하여 먼지등과 같은 이물질이 포함된 공기를 흡입한 후 본체 내부에서 이물질을 걸러내는 가전제품이다.In general, a vacuum cleaner is a home appliance that filters foreign matters from the inside of the body after inhaling air containing foreign matters such as dust by using a vacuum pressure generated by a motor mounted inside the cleaner body.
상기 모터는 진공청소기 내부의 공기를 외부로 배출하여 내부 압력을 낮추는 것에 의해 흡입력을 발생시킨다. 이렇게 발생한 흡입력은 흡입수단을 통해 청소면의 먼지등의 이물질을 외부공기와 함께 흡입하여 집진장치에 의해 제거할 수 있도록 한다.The motor generates suction by lowering the internal pressure by discharging the air inside the vacuum cleaner to the outside. The suction force generated in this way allows the foreign matter such as dust on the cleaning surface to be sucked together with the external air through the suction means to be removed by the dust collector.
모터는 전기에너지로부터 회전력을 얻는 기계로서, 스테이터와 로터를 구비한다. 로터는 스테이터와 전자기적으로 상호 작용하도록 구성되고, 자기장과 코일에 흐르는 전류 사이에서 작용하는 힘에 의해 회전한다. A motor is a machine that obtains rotational force from electrical energy and includes a stator and a rotor. The rotor is configured to electromagnetically interact with the stator and is rotated by a force acting between the magnetic field and the current flowing in the coil.
모터는 로터를 회전시켜, 로터와 함께 회전하는 흡입팬에 의해 흡입력을 발생시키게 되고, 이러한 구성들은 하나의 모듈로 배치될 수 있다. 그러나 모터와 모터를 고정시키는 구성과, 흡입팬등의 구성이 서로의 공간을 간섭하게 되어 청소기의 전체적인 크기가 커지게 되어 문제가 된다.The motor rotates the rotor to generate suction force by the suction fan rotating with the rotor, and these configurations can be arranged in one module. However, the configuration in which the motor and the motor are fixed, and the configuration of the suction fan and the like interfere with each other's space, resulting in an increase in the overall size of the cleaner.
