Problems solved by technology
Its disadvantage is that the coil welding requires high technology and is difficult to manufacture, and a large amount of oxygen-free copper material is used, so the manufacturing cost is high
At the same time, the wall of the combustion chamber with coiled pipes is prone to condensate water at low temperature in winter, which will affect the life of the heat exchanger
The other is to install heat insulating material on the inner wall of the combustion chamber. The cost of the heat insulating material is high, and the heat insulating effect is poor when the thickness and sealing performance of the heat insulating material are insufficient.

The invention discloses a combustion chamber and gas equipment. The combustion chamber comprises a first surrounding plate located on the outer side and a second surrounding plate located on the inner side, the second surrounding plate forms a combustion cavity, the first surrounding plate and the second surrounding plate are arranged in a spaced mode to form an air channel communicating with the combustion cavity and surrounding the combustion cavity in the circumferential direction, the air channel is divided into a plurality of independent air cavities in the circumferential direction, each air cavity is provided with an independent air inlet hole and an independent air outlet hole, and under the condition that negative pressure is formed in the combustion cavity, air in the air channel is fed into the combustion cavity. According to the combustion chamber, the air channel in the circumferential direction is divided into the multiple independent air cavities, the cold air distribution condition is improved through the multi-air-cavity structure, the whole first surrounding plate is evenly cooled, and therefore the service life of parts of the gas equipment is prolonged; and air can be conveyed to the combustion cavity from multiple directions at the same time, sufficient secondary air is supplied, and the combustion efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of water heaters, and more specifically, to a combustion chamber and gas equipment. Background technique [0002] In order to prevent the high temperature heat energy from being transmitted outwards and damage the life of other parts of the gas equipment, the existing combustion chambers usually include the following two types. One is to use oxygen-free copper to surround the combustion chamber, and to coil water pipes on the outer wall of oxygen-free copper to cool down , to prolong the service life of parts. Its disadvantages are that coil welding has high requirements on the process, the manufacturing is difficult, and a large amount of oxygen-free copper material is used, so the manufacturing cost is high. At the same time, the wall of the combustion chamber with coiled tubes is prone to condensed water in winter when the temperature is low, which will affect the life of the heat exchanger. The other i...
