상기 송풍기(10)로부터 공급된 공기와 가스유입구(21)를 통해 유입된 연소용 가스는 혼합유체 연결관(20)에서 취합되어 그 상측에 구비된 버너바디(30)와 분배판(40)으로 둘러싸인 믹싱챔버(60)로 유입되어 버너(50)의 연소에 적합한 상태로 혼합된 뒤에 분배판(40)에 일정 간격으로 형성된 분배홀(41)을 통과하여 그 상측에 구비된 버너(50)로 공급된다.The air supplied from the blower 10 and the gas for combustion introduced through the gas inlet 21 are collected in the mixed fluid connection pipe 20, and the burner body 30 and the distribution plate 40 provided on the upper side thereof. After entering the enclosed mixing chamber 60 and mixed in a state suitable for combustion of the burner 50, it passes through the distribution holes 41 formed at a predetermined interval on the distribution plate 40 to the burner 50 provided above.

And the number is not limited to the embodiments shown in Figure 5, it may be modified in various other forms.

이하, 본 발명의 작용을 설명한다.The operation of the present invention will be described below.

보일러 또는 온수기가 작동되면, 설정된 연소 부하에 따라 송풍기(110,110a)의 회전수에 따른 공기의 공급량과 가스의 공급량이 조절되고, 공급된 공기와 가스는 혼합유체 연결관(120,120a)에서 취합되어 그 상측에 결합된 돌출관(130)을 통과하여 버너바디(170) 내측의 공명실 커버(150)와 분배판(160) 사이에 형성된 믹싱챔버(180)로 유입된다. When the boiler or the water heater is operated, the air supply amount and the gas supply amount according to the rotation speed of the blowers 110 and 110a are adjusted according to the set combustion load, and the supplied air and gas are collected in the mixed fluid connection pipe 120 and 120a. Passing through the protruding tube 130 coupled to the upper side is introduced into the mixing chamber 180 formed between the resonance chamber cover 150 and the distribution plate 160 inside the burner body 170.

이와 같이 공기와 가스가 믹싱챔버(180)의 내부 공간으로 유입되어 버너(170)의 연소에 적합한 상태로 혼합되는 과정에서 공기와 가스의 유동 및 압력변화에 의해 소음을 발생하게 되며, 부하가 커질수록 이에 비례하여 소음은 더욱 심해진다. As air and gas flow into the internal space of the mixing chamber 180 and are mixed in a state suitable for combustion of the burner 170, noise is generated by the flow and pressure change of the air and gas, and the load increases. The more it is proportionate to the noise.

믹싱챔버(180)에서 혼합유체의 유동과 함께 전파되는 소음은 공명실 커버(150)에 형성된 공명실 연통홀(152)을 통해 공명실 커버(150)와 버너바디(140)로 둘러싸인 공명실(190) 내부로 유입되고, 공명실(190)의 체적과 공명실 연통홀(152)의 크기 및 개수에 의해 결정되는 특정 주파수 대역에서 공명작용에 의해 감쇄된다. 즉, 공명실(190)에서의 공명작용은 혼합유체 연결관(120,120a)과 돌출관(130) 및 믹싱챔버(180)로 연결되는 유로에서 발생한 혼합유체의 유동 소음은 공명실 연통홀(152)을 통해 공명실(190) 내부로 전파되어 공명실(190) 내부 공간에서 이동하는 과정에서 소음의 음파에너지가 열에너지로 변환되어 소음이 감쇄되며, 일반적인 소음기에 설치되는 흡음재를 사용하지 않더라도 소음을 효과적으로 억제할 수 있게 된다. Noise propagated with the flow of the mixed fluid in the mixing chamber 180 is the resonance chamber surrounded by the resonance chamber cover 150 and the burner body 140 through the resonance chamber communication hole 152 formed in the resonance chamber cover 150 ( 190 is introduced into the interior, and is attenuated by resonance in a specific frequency band determined by the volume of the resonance chamber 190 and the size and number of the resonance chamber communication holes 152. That is, the resonance action in the resonance chamber 190 is the flow noise of the mixed fluid generated in the flow path connected to the mixing fluid connection pipe (120, 120a) and the protruding pipe 130 and the mixing chamber 180 is the resonance chamber communication hole (152) In the process of propagating into the resonance chamber 190 and moving in the internal space of the resonance chamber 190, the sound wave energy of the noise is converted into thermal energy, and the noise is attenuated, even if the sound absorbing material installed in the general silencer is not used. It can be effectively suppressed.

이 경우 공명실 커버(150)에 형성된 공명실 연통홀(152)의 형상과 크기 및 개수는 믹싱챔버(180)에서 발생하는 소음의 주파수 대역을 고려하여 다양한 형태로 설계될 수 있다.In this case, the shape, size and number of the resonance chamber communication holes 152 formed in the resonance chamber cover 150 may be designed in various forms in consideration of the frequency band of the noise generated in the mixing chamber 180.

상기와 같이 본 발명에서는 버너 시스템(100,100a)에 별도의 소음기를 설치하지 않고, 혼합유체 연결관(120,120a)의 상단에 돌출관(130)의 일단(130a)을 결합하고 돌출관(130)의 타단(130b)은 버너커버(140)의 바닥면을 관통하여 믹싱챔버(180)의 내측으로 연장하고, 상기 돌출관(130)의 타단(130b)과 버너바디(140)의 내측면에 공명실 커버(150)의 돌출관 삽입구멍(151)과 공명실 커버(150)의 가장자리부를 결합하는 간단한 결합구조에 의해 공명실(190)을 마련함으로써, 공기와 가스의 유동에 의한 소음을 효과적으로 제거할 수 있게 되므로, 가스보일러나 가스온수기의 설정 부하의 크기에 관계없이 조용한 운전이 가능해진다.In the present invention as described above, without installing a separate silencer in the burner system (100,100a), the one end (130a) of the protruding pipe 130 is coupled to the upper end of the mixed fluid connection pipe (120,120a) and the protruding pipe 130 The other end 130b of the penetrating penetrates the bottom surface of the burner cover 140 and extends into the mixing chamber 180, and resonates on the other end 130b of the protruding pipe 130 and the inner surface of the burner body 140. By providing the resonance chamber 190 by a simple coupling structure that combines the protruding pipe insertion hole 151 of the seal cover 150 and the edge of the resonance chamber cover 150, the noise caused by the flow of air and gas is effectively removed. This enables quiet operation regardless of the magnitude of the set load of the gas boiler or gas water heater.
