fig. 2 is an exploded view of the present invention;
fig. 3 is a cross-sectional view of the bellows of the present invention;
fig. 4 is a schematic structural view of the wind chamber of the present invention when partially disassembled.
[ detailed description ] embodiments
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1 to 4, a gas water heater comprises a housing 1, a burner assembly 2 and a heat exchanger 3 heated by the burner assembly 2 are arranged in the housing 1, a water pipe 31 is arranged on the heat exchanger 3, a water inlet 4 is arranged on the housing 1, a water pump 5 is connected to the water inlet 4, a water outlet 51 of the water pump 5 is connected with a water pipe inlet 311 of the water pipe 31 through a corrugated pipe 6, and a plurality of grooves 61 are arranged on the inner wall of the corrugated pipe 6. The utility model discloses gas water heater, the water pump passes through bellows 6 and 3 flexonics of heat exchanger, bellows 6 can warp the absorption vibration at water pump 5 during operation, and the noise that water pump 5 work produced gets into back in bellows 6, take place reflection and interference phenomenon in the recess 61 of noise meeting bellows 6, the internal sufficient reflection in recess 61, intercrossing, cause the energy of consuming energy of each other, make the noise energy decay, reach the effect of noise reduction, moreover, the steam generator is simple in structure, filter vibration and noise that water pump 5 produced well, avoid taking place waterway system resonance phenomenon.
The corrugated pipe 6 is a flexible metal corrugated pipe made of stainless steel material, and has good temperature resistance and pressure resistance, certainly, in practical application, the plastic corrugated pipe is not eliminated, and the corrugated pipe can still filter the vibration and noise generated by the water pump 5, and has good corrosion resistance and relatively weak temperature resistance and pressure resistance compared with the metal corrugated pipe.
As shown in fig. 1, the lower end of the heat exchanger 3 is communicated with the burner assembly 2, the upper end of the heat exchanger 3 is provided with an air cavity 7 communicated with the inside of the heat exchanger 3, and the air cavity 7 is provided with a fan 8 for drawing air in the air cavity 7 out of the shell 1. Specifically, the burner assembly 2 includes a gas proportional valve 21 communicated with the gas inlet 12, and a burner 22 disposed on the gas proportional valve 21, wherein the burner 22 is provided with an air inlet 221 through which air in the housing 1 enters the burner 22.
