본 발명은 진공청소기의 소음저감장치에 관한 것으로 특히 흡입덕트의 입구에서 유속의 차이에 의하여 발생되는 소음을 저감하도록한 것이다.The present invention relates to a noise reduction device of a vacuum cleaner, in particular to reduce the noise caused by the difference in flow velocity at the inlet of the suction duct.
종래의 진공청소기는 제1도와 같이 팬모터의 구동에 따라 흡입구를 통하여 본체(1)내로 흡입된 먼지를 집진하는 먼지집진실(2)과 상기 먼지집진실(2)을 통과한 공기가 통과흔 먼지필터(3)와 상기 먼지필터(3)를 통과한 공기가 흡입되는 흡입덕트(4)와 상기 흡입덕트(4)로 흡입된 공기는 모터케이스(5)를 통과하여 배기구(6)로 배기되도록 구성되었다.In the conventional vacuum cleaner, as shown in FIG. 1, the air passing through the dust collecting chamber 2 and the dust collecting chamber 2 which collects the dust sucked into the main body 1 through the suction port as the fan motor is driven is passed. The suction duct 4 through which the dust filter 3 and the air passing through the dust filter 3 are sucked in and the air sucked into the suction duct 4 pass through the motor case 5 to exhaust to the exhaust port 6. It was configured to be.
이와같이 구성된 상태에서 팬모터가 구동하게 되면 바닥의 먼지가 공기와 함께 흡입구로 흡입되어 본체(1)내의 먼지집진실(2)로 흡입된다.When the fan motor is driven in the state configured as described above, dust on the floor is sucked into the suction port together with the air and sucked into the dust collecting chamber 2 in the main body 1.
상기 먼지집진실(2)에 흡입된 먼지는 먼지집진실(2)에 집진되고 공기는 먼지집진실(2)을 통과하여 먼지필터(3)를 통과하면서 미세한 먼지는 걸리고 공기는 통과된다.The dust sucked into the dust collecting chamber 2 is collected in the dust collecting chamber 2, and the air passes through the dust collecting chamber 2 and passes through the dust filter 3, where fine dust is caught and air passes.
이와같이 먼지필터(3)를 통과한 공기는 흡입덕트(4)와 모타케이스(5)를 통과하여 배구기(6)로 배출되었다.As such, the air passing through the dust filter 3 passes through the suction duct 4 and the motor case 5 and is discharged to the volleyball 6.
이때, 흡입덕트(4)의 입구로 흡입되는 유속(A)은 제2도에서 보는 바와같이 상부와 하부는 상대적으로 가운데 보다 느리게 나타난다.At this time, the flow rate (A) sucked into the inlet of the suction duct (4) is relatively slower than the middle upper and lower as shown in FIG.
따라서, 유속(A)이 다른 공기가 불균일한 유속으로 흡입되어 균일기공을 가진먼지필터를 통과하기 때문에 흡입덕트(4)로 흡입되면서 큰 유체소음이 발생하게 되었다.Therefore, since the air of different flow rates A is sucked at an uneven flow rate and passes through a dust filter having uniform pores, large fluid noise is generated while being sucked into the suction duct 4.
이와같이 흡입되는 유체가 균일한 기공 및 두께를 가진 먼지필터를 통과한 후 흡입덕트 입구에서의 유속이 각부분에서 서로 다르게 나타난다. 즉, 흡입덕트 입구의 상부와 하부는 상대적으로 가운데 부분보다도 유속이 느리게 되고 이 불균일일한 유속에 의해 흡입덕트 입구에서 큰 유체소음이 유발되고 청소기 본체 소음에서 중요한 소음원으로 작용하는 문제점이 있었다.After the suctioned fluid passes through the dust filter with uniform pore and thickness, the flow velocity at the inlet duct is different at each part. That is, the upper and lower portions of the suction duct inlet are relatively slower than the middle portion, and this nonuniform flow rate causes a large fluid noise at the suction duct inlet and acts as an important noise source in the cleaner body noise.
본 발명은 이러한 점을 감안하여 청소기 모터의 구동에 의해 흡입력이 발생할때 흡입덕트 입구 각부분에서의 유속의 차이에 의해 발생되는 유체소음을 각부분 유속에 따라 필터의 두께를 달리하거나 필터의 가공율을 달리함으로써 유속을 균일하게 하여 유체소음을 저감하는데 목적이있다.In view of the above, the present invention is to change the thickness of the filter according to the flow rate of the filter or the processing rate of the filter according to the flow rate of the fluid noise generated by the difference in the flow rate at each part of the suction duct when the suction force is generated by the drive of the cleaner motor The purpose is to reduce fluid noise by making flow velocity uniform.
본 발명 진공청소기의 소음저감장치는 제3도에 의하여 설명한다.The noise reduction device of the vacuum cleaner of the present invention will be described with reference to FIG.
먼지집진실을 통과한 공기가 먼지필터(101)를 통하여 흡입덕트(102)로 흡입될때 유속(A)의 불균형을 균일하게하여 주도록 하기 위하여 유속(A)이 느린부분의 먼지필터(101) 부분을 얇게 구성하고, 유속이 빠른부분의 먼지필터(101)부분을 두껍게 구성하여 유체소음을 저감하도록 구비하였다.Part of the dust filter 101 in a portion where the flow rate A is slow to uniformize the flow rate A when the air passing through the dust collecting chamber is sucked into the suction duct 102 through the dust filter 101. It was configured to make a thin, thick dust filter 101 portion of the fast flow rate portion was provided to reduce the fluid noise.
그리고, 본 발명의 다른 실시예를 제4도에 의하여 설명한다.Another embodiment of the present invention will be described with reference to FIG.
먼지집진실을 통과한 공기가 먼지필터(201)를 통하여 흡입덕트(202)로 흡입될때 유속(A)의 불균형을 균일하게 하여 주도록 하기 위하여 유속이 느린부분의 먼지필터(201)부분은 기공의 크게 구성되고, 유속이 빠른부분의 먼지필터(201)부분은 기공이 작게 구성되어 유체소음을 저감하도록 구비하였다.When the air passing through the dust collection chamber is sucked into the suction duct 202 through the dust filter 201, the dust filter 201 part of the slow flow rate is formed in the pores in order to make the unbalance of the flow rate A uniform. The dust filter 201 portion of the large, high flow rate portion is provided with small pores to reduce fluid noise.
이와같이 구성된 본 발명의 작용효과를 제3도에 의하여 서명하면If the effect of the present invention configured as described above is signed by FIG.
먼지필터(101)를 균일한 기공율을 가진 먼지필터(101)의 두께를 달리하여 유속을 균일하게 하는것으로써, 유속이 빠른부분에 대해서는 저항을 크게하여 유속을 감소시키기위해 필터의 두께를 두껍게하고, 상대적으로 유속이 느린부분에 대해서는 필터 두께를 얇게 함으로써 액티브필터를 통과한 후 흡입덕트(102)입구에서의 유속을 균일하게하여 유체흐름을 원활하게 하여 유체소음을 저감한다.By varying the thickness of the dust filter 101 having a uniform porosity, the dust filter 101 is made uniform, and the thickness of the filter is thickened to reduce the flow rate by increasing the resistance for the fast flow rate part. In the case of a relatively slow flow rate, the thickness of the filter is made thin so that after passing through the active filter, the flow velocity at the inlet duct 102 is uniformized to smooth the flow of fluid, thereby reducing the noise of the fluid.
그리고, 본발명의 다른 실시예를 제4도에 의하여 설명하면And another embodiment of the present invention will be described with reference to FIG.
먼지필터(201)를 균일한 두께로하고 각 부분의 유속에 따라 필터의 기공율을 달리하여 유속을 균일하게 하는 것으로써, 유속이 빠른부분에 대해서는 저항을 크게하여 유속을 감속시키기 위해 기공을 조밀하게 하고 상대적으로 유속이 느린부분에 대해서는 기공을 크게하여 필터통과 후 흡입덕트(202)입구에서의 유속을 균일하게하여 유체소음을 저감하였다.The dust filter 201 is made to have a uniform thickness and the flow rate is made uniform by varying the porosity of the filter according to the flow rate of each part, so that the pores are densely densified to reduce the flow rate by increasing the resistance in the fast flow rate part. In the case of the relatively slow flow rate, the pores were enlarged to uniform the flow rate at the inlet duct 202 after the passage of the filter, thereby reducing the fluid noise.
이와같은 본발명은 각부분의 유속의 빠르기에 따른 먼지필터의 두께를 달리하거나 기공의 크기를 달리하여 액티브필터 통과 후의 불균일한 유속으로 인한 유체충돌음을 현저히 저감시켜 전체 청소기 소음저감에 큰 효과를 얻을 수 있다.The present invention can significantly reduce the fluid collision caused by the uneven flow rate after passing through the active filter by varying the thickness of the dust filter or the size of the pores according to the speed of the flow rate of each part, thereby significantly reducing the overall cleaner noise. Can be.
