Embodiment Construction

[0051] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0052] Such as Figure 1 to Figure 2 As shown, the combustion chamber includes a fire row 1 and a combustion chamber 2 for accommodating the fire row 1. The top of the combustion chamber 2 is an open opening, and the upper end of the fire row 1 with a fire hole protrudes to the top of the combustion chamber 2. . The front of the combustion chamber 2 has a row of gas inlets 3, and the gas inlets 3 communicate with the gas inlets of the fire row 1.

[0053] An air intake chamber 4 is provided below the combustion chamber 2 , a number of air intake holes 5 are provided between the intake chamber 4 and the combustion chamber 2 , and an air intake port 7 is provided below the air intake chamber 4 . The external fan blows air into the air intake chamber 4 through the air inlet 7, and the air in the air intake chamber 4 enters the ...

Abstract

The invention discloses a sound attenuation structure and a combustion chamber comprising the same. The sound attenuation structure is arranged on the inner surface of a cavity to be denoised. A soundattenuation cavity is formed in the sound attenuation structure. The sound attenuation structure is provided with at least sound attenuation port facing the cavity. The sound attenuation cavity communicates with the cavity through the sound attenuation ports. According to the sound attenuation structure and the combustion chamber comprising the same, the sound attenuation structure with the soundattenuation cavity is arranged on the inner surface of the cavity; and noise goes into the sound attenuation cavity through the sound attenuation ports, continuously collides in the sound attenuationcavity to cause energy loss, and the sound attenuation and noise reduction purposes are achieved accordingly. The sound attenuation structure is applied to the combustion chamber of a gas water heater. During operation of the combustion chamber, noise generated when an external draught fan blows in air and noise generated from combustion in the combustion chamber can be reduced.

Description

technical field [0001] The invention relates to a sound-absorbing structure and a combustion chamber containing it. Background technique [0002] Household gas water heater is a common hot water supply equipment in daily life. It has the advantages of fast hot water output, constant water temperature, less scaling, small footprint, and no control of water volume. It is favored by consumers. However, during the combustion process of the gas water heater, due to the collision between the flames inside the combustion chamber, relatively large noise will be generated, and users will have relatively large complaints during use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sound-absorbing structure and a combustion chamber containing it in order to overcome the defect of high noise in the combustion chamber of the gas water heater in the prior art. [0004] The present invention solves the above technical problem...
