Abstract

The invention discloses a gas water heater with the noise reduction function. The gas water heater comprises a water tank shell, a combustor and a heat exchanger, the combustor and the heat exchangerare arranged in the water tank shell, the gas water heater further comprises a first sound guide channel, a second sound guide channel and a noise reduction cavity, a first inlet and a second inlet are formed in the noise reduction cavity, one end of the first sound guide channel is communicated with the water tank shell, the other end of the first sound guide channel is communicated with the first inlet, one end of the second sound guide channel is communicated with the water tank shell, the other end of the second sound guide channel is communicated with the second inlet, and a metasurface structure is arranged at the position, between the first inlet and the second inlet, in the noise reduction cavity. The metasurface structure comprises a plurality of baffle assemblies, each baffle assembly comprises a plurality of baffles which are distributed in a staggered manner, the noise is low, and the use experience of a user can be improved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a gas water heater with a noise reduction function. Background technique [0002] In related technologies, gas water heaters are widely recognized by consumers for their advantages of energy saving and environmental protection, but the problem of noise during operation of gas water heaters is also troublesome. It is understood that the national standard requires that the noise of gas water heaters be no more than 65 decibels when they are burning, while the noise emitted by ordinary gas water heaters when they are running is generally above 55 decibels. If the noise level is too high, it will affect people's hearing. According to medical experiment data, the noise value of more than 50 decibels is equivalent to talking loudly, which affects normal life; 60-70 decibels is equivalent to standing on the continuous flow of the road, which will make people upset and distracted;...
