본 발명은 진공청소기의 소음저감장치에 관한 것으로서 특히 모터의 팬회전에 의해 발생하는 유체소음을 저감하기 위해 모터 케이스를 빠져나가는 유체를 수동 터보팬 케이스에 장착된 수동터보팬을 흡입시켜 수동 터보팬을 회전시킴으로 소음의 직접노출을 막고 소리 에너지를 운동에너지로 변화시킴으로 해서 진공청소기의 소음을 저감시킬 수 있도록 한 것이다.The present invention relates to a noise reduction device of a vacuum cleaner, and in particular, to reduce fluid noise generated by a fan rotation of a motor, a manual turbo fan is made by sucking a manual turbo fan mounted on a manual turbo fan case to remove fluid from the motor case. By rotating the system to prevent direct exposure of the noise and change the sound energy into kinetic energy to reduce the noise of the vacuum cleaner.
종래 진공청소기는 제1도에 도시된 바와 같이 청소기체(1)와, 상기 본체(1)내부에 먼지를 집진하는 먼지집진실(2)과, 상기 집진실(2)을 통과한 먼지를 걸러주는 먼지필터(3)와, 구동원인 팬모터(4)를 감싸고 있는 모터케이스(5)와, 상기 모터케이스(5)와 본체(1) 후면에는 각각 배기구(6)가 구성되었다.As shown in FIG. 1, a conventional vacuum cleaner filters the cleaner body 1, the dust collecting chamber 2 for collecting dust in the main body 1, and the dust that has passed through the dust collecting chamber 2, as shown in FIG. The main dust filter 3, the motor case 5 surrounding the fan motor 4 as a driving source, and the exhaust port 6 were respectively formed on the motor case 5 and the main body 1 rear surface.
종래 기술의 동작은 본체 내부에 장착된 팬모터(4)의 회전에 의해 흡입력이 발생하게 되면 이때 각종 오물이 흡입구를 통해 먼지집진실(2)에 집진되고 공기는 모터케이스(5)의 전면에 형성된 먼지필터(3)를 통해 팬모터(4)를 지나 상기 모터케이스(5)와 본체(1) 후면에 형성된 배기구(6)를 통해 대기중으로 빠져나가게 된다.When the suction force is generated by the rotation of the fan motor 4 mounted inside the main body, various types of dirt are collected in the dust collecting chamber 2 through the suction port, and air is applied to the front of the motor case 5. It passes through the fan motor 4 through the formed dust filter 3 and exits into the atmosphere through the exhaust port 6 formed at the rear of the motor case 5 and the main body 1.
그러나 팬모터(4)의 회전에 의해 흡입력이 발생하여 흡입되는 공기는 팬모터(4)를 통과해서 모터케이스(5)에 있는 케이스 배기구를 통과해서 본체 뒤쪽의 배기구(6)로 바로 나가게 되는데 이때 유체에 의해 발생하는 소음이 손실 없이 직접 배기구를 통해 빠져나옴으로서 청소기의 소음원으로 작용하게 되는 문제점이 있었다.However, the suction force is generated by the rotation of the fan motor 4, and the sucked air passes through the fan motor 4, passes through the case exhaust port of the motor case 5, and exits directly to the exhaust port 6 behind the main body. There is a problem that the noise generated by the fluid acts as a noise source of the cleaner by directly exiting through the exhaust port without loss.
본 발명은 이러한 점을 감안하여 모터케이스 후면에서 팬모터를 지나 배출되는 유체가 통과되어 유채소음을 저감시킬 수 있도록 수동 터보팬을 장착함으로서, 유체소음의 소지에너지 일부분을 수동터보팬을 회전시키는 운동에너지로 전환시킴으로서 배기량의 균등분배를 통해 청소기에서 발생하는 유체소음을 저감시킬 수 있도록 하는데 목적이 있다.The present invention is equipped with a passive turbo fan to reduce the rapeseed noise by passing the fluid discharged through the fan motor from the rear of the motor case in consideration of this point, the movement of the manual turbo fan to rotate the energy portion of the fluid noise The purpose of the present invention is to reduce fluid noise generated by a cleaner by equally distributing the displacement by converting it into energy.
본 발명을 제2도 내지 제5도에 의하여 설명한다.The invention is illustrated by FIGS. 2 to 5.
본 발명의 구성은 본체(101) 내부에 팬모터(102)를 장착한 모터케이스(103)를 설치하고, 상기 모터케이스(103) 후면에는 팬모터(102)를 지나 배출되는 유체가 통과할 수 있도록 원형의 구멍을 뚫어 놓고, 상기 모터케이스(103) 후면에 모터케이스와 연결 가능한 원통형의 수동터보팬케이스(104)를 장착하고, 상기 터보팬케이스(104)에는 수동터보팬(105)이 설치되고, 상기 수동터보팬의 축(106)은 베어링(107)에 의해 지지되도록 구성한다.In the configuration of the present invention, the motor case 103 having the fan motor 102 installed therein is installed in the main body 101, and the fluid discharged through the fan motor 102 can pass through the rear of the motor case 103. To make a circular hole so as to mount a cylindrical manual turbo fan case 104 that can be connected to the motor case on the back of the motor case 103, the turbo fan case 104 is installed a manual turbo fan 105 The shaft 106 of the passive turbo fan is configured to be supported by the bearing 107.
도면중 미설명 부호 108은 수동터보팬의 회전에 의해 유체가 통과하는 배기구를 나타낸다.In the figure, reference numeral 108 denotes an exhaust port through which the fluid passes by the rotation of the manual turbofan.
이와 같이 구성된 상태에서 모터케이스(103)내부에 설치된 팬모터(102)의 회전에 의해 흡입력이 발생하게 되는데 이때 유입되는 유체(공기)는 먼지집진실을 지나 상기 모터케이스(103)내에 설치된 팬모터(102)로 유입되고 이 유입된 유체는 다시 상기 모터케이스(103)후면에 뚫어진 원형구멍으로 빠져나간다. 빠져나온 강한 유체는 수동터보팬 케이스(108)로 유입되는 수동터보팬케이스(108)에 설치된 수동터보팬(105)을 회전시킨다.In this configuration, the suction force is generated by the rotation of the fan motor 102 installed inside the motor case 103. In this case, the fluid (air) flowing through the dust collecting chamber is installed in the motor case 103. The fluid flows into the 102 and the fluid flows back into the circular hole drilled on the rear surface of the motor case 103. The strong fluid exits the manual turbofan 105 installed in the manual turbofan case 108 flowing into the manual turbofan case 108.
그리고 제5도에서 보는 바와 같이 유체는 수동터보팬(105) 입구(A)로 유입되면서 터보팬을 회전시키고 다시 팬출구(B)를 통해서 수동터보팬 케이스(104)에 설치된 터보팬케이스 배기구(108)를 통해 배기되고 이 배기된 유체는 본체의 배기구를 통해 다시 대기중으로 빠져나가게 된다.As shown in FIG. 5, the fluid flows into the inlet A of the manual turbo fan 105 and rotates the turbo fan, and again through the fan outlet B, the turbo fan case exhaust port installed in the manual turbo fan case 104. 108, which is then exhausted back into the atmosphere through the exhaust of the body.
이때 유체의 일부 소지에너지는 수동터보팬을 회전시키는 운동에너지로 바뀌게 되고 이로 인하여 수동터보팬을 통해 배출되는 유체소음은 사기 팬모터에서 배출되는 유체소음보다 현저하게 저감되게 되는 것이다.At this time, some of the holding energy of the fluid is changed to the kinetic energy to rotate the passive turbo fan, and thus the fluid noise discharged through the passive turbo fan is significantly reduced than the fluid noise discharged from the fan fan motor.
이상에서 살펴본 바와 같은 본 발명은 팬모터의 회전에 의해 흡입되는 유체소음의 소지에너지 일부분을 수동터보팬을 회전시키는 운동에너지로 전환시킴으로 팬출구로부터 균일한 유량을 배출하도록 하여 청소기에서 발생하는 유체소음을 저감시킬 수 있는 발명이다.As described above, the present invention converts a portion of the energy consumption of the fluid noise sucked by the rotation of the fan motor into kinetic energy for rotating the manual turbo fan, thereby discharging a uniform flow rate from the fan outlet, thereby generating fluid noise from the cleaner. The invention can reduce the
