It relates to a sound absorbing device.
일반적으로 진공청소기는 팬모터의 구동으로 발생된 강력한 흡인력에 의해 바닥이나 구석, 틈, 벽면에 붙은 먼지나 기타의 이물질을 흡입하여 내부의 집진팩에 의해 포집할 수 있도록 된 것이다.In general, the vacuum cleaner is capable of collecting dust and other foreign matter on the floor, corners, cracks, and walls by the strong suction force generated by the driving of the fan motor, and collecting the dust by the internal dust collecting pack.
이러한 진공청소기(10)는 첨부도면 도 1 에 도시된 바와 같이 하부의 바디(11)와 상부의 바디커버(12)가 상하방향에서 서로 대합되는 구조로 되어 있으며, 바디(11)의 전후방에는 각각 바퀴(12a)(12b)가 설치되어 이동하면서 청소작업을 할 수 있도록 되어 있고, 전방에는 다단으로 연장됨과 동시에 착탈가능한 플렉시블 흡입관(도시 않됨)이 설치되어 있다.The vacuum cleaner 10 has a structure in which the lower body 11 and the upper body cover 12 are opposed to each other in an up and down direction as shown in FIG. 1, respectively, in front and rear of the body 11. The wheels 12a and 12b are installed to allow cleaning while moving, and a flexible suction pipe (not shown) that is extended in multiple stages and detachable at the same time is installed at the front.
또, 상기 진공청소기(10)의 내부는 격벽(14)에 의해 전방측에는 집진실(15), 후방측에는 흡음기능을 갖춘 모터수납실(16)로 각각 구획되어 있으며, 이러한 집진실(15)에는 상기 플렉시블 흡입관으로부터 흡입된 먼지나 기타 이물질등을 포집하기 위한 집진팩(17)이 착탈가능하게 설치되어 있는 한편, 상기 모터수납실(16)에는 상기 집진팩(17)을 통해 상기 플렉시블 흡입관(13)에 부압이 걸리도록 하는 팬모터(18)가 방진구조를 갖는 흡음케이스(20)에 수납된 상태에서 설치되어 있었고, 이 흡음케이스(20)로부터 상기 바디커버(12)의 후방측 배기구(12a)로 이어지는 배기통로(12b)가 형성되어 흡입된 공기가 이곳을 통하여 밖으로 배출되도록 구성되어 있었다.In addition, the interior of the vacuum cleaner 10 is partitioned by a partition 14 into a dust collecting chamber 15 at the front side and a motor storage chamber 16 having a sound absorbing function at the rear side. A dust collecting pack 17 for collecting dust or other foreign matter sucked from the flexible suction pipe is detachably installed, while the motor storage chamber 16 has the flexible suction pipe 13 through the dust collecting pack 17. Fan motor 18 to be subjected to negative pressure is installed in the sound absorbing case 20 having a dustproof structure, and from the sound absorbing case 20, the rear exhaust port 12a of the body cover 12 is provided. The exhaust passage 12b leading to) was formed so that the sucked air was discharged through the place.
또한, 상기 격벽(14)에는 집진실(15)로부터 팬모터(18)로 이어지는 흡기통로(14a)가 형성되어 있었고, 이 흡기통로(14a)에는 먼지와 같은 미세한 입자를 걸러내기 위한 필터(22)가 위치되어 있었다.In addition, the partition 14 has an intake passage 14a extending from the dust collecting chamber 15 to the fan motor 18, and the filter 22 for filtering out fine particles such as dust is formed in the intake passage 14a. ) Was located.
또, 위와 같은 종래의 흡음케이스(20)는 첨부도면 도2에 도시된 바와 같이 전후방측으로 2분할되는 전방케이싱(23)과 후방케이싱(24)이 다수의 볼트(25)에 의해 대합되어 있었으며, 그 내부에는 팬모터(18)에 씌워지는 방진용의 패킹(26)과 팬모터(18)를 지지하기 위한 방진용의 모터마운트(27)가 설치되어 있었고, 상기 팬모터(18)와 후방케이싱(24)의 사이에 형성된 공간의 중간에 위치되어 우회하는 공기통로를 형성하기 위한 원통형의 에어가이드(28)가 설치되어 있었다.In addition, in the conventional sound absorbing case 20 as shown in FIG. 2, the front casing 23 and the rear casing 24, which are divided into two front and rear sides, are joined by a plurality of bolts 25, The inside of the fan motor 18 is provided with a dustproof packing 26 for covering the fan motor 18 and a motor mount 27 for dustproof for supporting the fan motor 18. The fan motor 18 and the rear casing are provided. Cylindrical air guides 28 were formed to form a bypass air passage located in the middle of the space formed between the 24.
즉, 플렉시블 흡입관을 통해 흡입된 공기는 집진팩(17) → 필터(22) → 격벽(14)의 흡기통로(14a) → 전방케이싱(23)의 흡기통로(23k)를 통한 흡음케이스(20) 내로의 유입 → 팬모터(18)의 내부 → 팬모터(18)의 배기구(18u) → 에어가이드(28)와 후방케이싱(24)의 사이에 형성된 공기통로 → 후방케이싱(24)의 배기통로(24g) → 바디커버(12)의 배기구(12a)를 거쳐 외부로 배출되도록 구성되어 있었다.That is, the air sucked through the flexible suction pipe is the sound absorption case 20 through the intake passage 14a of the dust collecting pack 17 → the filter 22 → the partition 14 → the intake passage 23k of the front casing 23.

이 때 상기 상부케이싱(31)과 하부케이싱(30)의 내주면에 설치된 흡음재(40)는 이 상부케이싱(31) 및 하부케이싱(30)과 에어가이드(34) 사이에 형성된 공기통로(42)로 흐르는 공기의 진동에너지를 흡수하는 작용을 하여 소음을 감소시키는 한편, 상기 상부케이싱(31)으로부터 하부케이싱(30)의 배기통로(30b)를 향하여 하향되도록 설치된 차음판(50)은 이 배기통로(30b)를 통해 바디(60)의 배기구(61)로 흐르는 공기의 흐름경로를 연장시킴으로써 소음에너지를 감소시키는 작용을하여 소음을 더욱더 감소시키게 되고, 이 차음판(50)에 부착되어 있는 흡음재(45)는 이 차음판(50)을 향해 부딪치는 공기에너지를 완충작용에 완화시켜 소음을 감소시키는 작용을 하게 된다.At this time, the sound absorbing material 40 installed on the inner circumferential surfaces of the upper casing 31 and the lower casing 30 is an air passage 42 formed between the upper casing 31 and the lower casing 30 and the air guide 34. The sound absorbing plate 50 installed so as to absorb the vibration energy of the flowing air to reduce noise and downward from the upper casing 31 toward the exhaust passage 30b of the lower casing 30 is provided with the exhaust passage ( By extending the flow path of air flowing through the exhaust port 61 of the body 60 through 30b), the noise energy is reduced to further reduce the noise, and the sound absorbing material 45 attached to the sound insulating plate 50 is provided. ) Acts to reduce the noise by alleviating the air energy impinging on the sound insulating plate 50 to the buffer action.
또한, 하부케이싱(30)의 배기통로(30b)를 통해 배출되는 공기는 배기필터(35)를 거치면서 오염된 진공청소기 내부의 순환공기가 완전하게 필터링되어 실외의 청청화를 꾀할 수 있게 된다.In addition, the air discharged through the exhaust passage 30b of the lower casing 30 passes through the exhaust filter 35 to completely filter the circulating air inside the contaminated vacuum cleaner to purify the outdoors.
이상에서 설명한 본 발명은 전술한 실시예 및 도면에 의해 한정되는 것은 아니고, 본 고안의 기술적 사상을 벗어나지 않는 범위내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 고안이 속하는 기술 분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have
따라서, 이상에서와 같은 본 발명은 흡음케이스가 상하방향으로 분리되는 형태로 되어 있으므로, 조립이 간편하게 되며, 그 내부의 공기통로에는 흡음재와 차음판이 설치되어 있으므로, 외부로 배출되는 공기에 의해 발생될 수 있는 소음을 보다 감소시킬 수 있을 뿐만 아니라 배기필터의 추가설치에 의해 오염된 진공청소기 내부의 공기의 청청화가 실현되는 매우 유용한 효과가 있다.Therefore, the present invention as described above has a form in which the sound absorbing case is separated in the vertical direction, so that the assembly is easy, and the sound passage and sound insulation plates are installed in the air passage therein, so that the air is discharged to the outside. Not only can the noise be reduced more, but the additional installation of the exhaust filter has a very useful effect of clarifying the air inside the contaminated vacuum cleaner.
