Below with reference to the attached drawing of specification, a specific embodiment of the invention is further described, is made of the invention Technical solution and its benefits are clearer.It describes embodiment below with reference to attached drawing to be exemplary, it is intended to solve The present invention is released, and is not considered as limiting the invention.
Additional aspect and advantage of the invention will become obviously in following description section, or practice through the invention Recognize.
Embodiment one
As shown in Figure 1, a kind of combustion chamber, comprising: burner 2, heat exchanger 3 in the shell 1 is arranged in shell 1, with And the air intake opening 4 and exhanst gas outlet 5 of setting on the housing, which is characterized in that the part of the shell is by flexible sheet 6 It constitutes.
Wherein, the flexible sheet 6 is high temperature resistant silicon film;The air intake opening 4 is located at the bottom of the shell 1, institute The top that exhanst gas outlet 5 is located at the shell 1 is stated, the burner 2 is located at the lower section of the heat exchanger 3, the flexible sheet 6 It is arranged on the side wall of the shell 1, close to the air intake opening 4 and lower than the burner 2.In this way, can be effectively relieved Noise caused by intake changes, and avoid flexible sheet 6 because of high temperature failure caused by contacting flame for a long time.
In other embodiments, the flexible sheet is made of metallic membrane that is deformable, resetting.The elastic membrane Piece is arranged on the side wall of the shell and is located at around the burner;In this way, to alleviating because gas flow is mutated and quick-fried Expansion noise caused by combustion has better effect.
In the present embodiment, the preferably described heat exchanger 3 includes the heat collecting sheet of several parallel arrangements and is interspersed in the heat collecting sheet On heat exchanger tube.In this way, heat exchange efficiency can not only be improved, moreover it is possible to balance flue gas, noise-decreasing.
Further, flexible sheet also can be set at the top of the shell 1, and the preferably flexible sheet is positioned at described Around exhanst gas outlet 5, to alleviate flue gas fluctuation bring expansion noise.
In actual work, combustion chamber pressure changes with the variation or fortuitous event of running parameter, when in combustion chamber When gas volume changes, flexible sheet can play buffer function, to reduce covibration, combustion chamber work is effectively reduced Make noise.
In conjunction with shown in Fig. 1, existing water heater when progress aerating or adds character and conduct work to be to cause combustion chamber in burning Internal pressure P1 changes, and pressure changes P2 by burner air hole and goes out pressure, can change original lower state at this time, At this moment air inlet is persistently entered the wind, in addition original burning indoor air flow disorder, can generate that internal pressure of combustion chamber P1 is suddenly big or suddenly small, this is existing It aggravates to will form resonance as lasting, to generate loud noise.And the present invention is carried out using flexible diaphragm and combustion chamber It connects and is effectively sealed, after intake and gas quantity sudden change, combustion chamber cavity volume is changed correspondingly, and realizes volume Buffering, effectively solution vibration problems, to avoid your resonance noise.
Embodiment two
A kind of gas and hot water equipment, including shell, are arranged in the combustion chamber in the shell, connect with the combustion chamber Water inlet pipe, outlet pipe, which is characterized in that the combustion chamber such as embodiment one;The gas and hot water equipment be gas heater or Burnt gas wall hanging furnace.It is existing that those of ordinary skill in the art can be used in as the specific structure of gas heater or burnt gas wall hanging furnace In the various technical solutions known with future, it is not detailed herein.
After being determined due to existing gas fired water heater or burnt gas wall hanging furnace main structure, burning chamber interior volume is immutable, And there is material therefor some strength to have certain probability when gas volume changes in cavity and covibration occur, thus Cause operating noise big.Gas and hot water equipment provided by the invention, since there is the shell of its combustion chamber certain deformation to reset Ability, when internal pressure of combustion chamber variation, corresponding change also occurs for burning chamber shell, to effectively solve resonance problem, reduces The operating noise of gas and hot water equipment.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention Protection scope.
