They are structurally and functionally provided with only one cavity for air supply or liquid fuel combustion, which is connected with the burner to form a cooking range. The defects of the hearth in use are as follows: 1. the waste heat of the hearth is not utilized, and the heat efficiency is low; 2. the burning fuel is not preheated, the burning efficiency is not high, and the energy consumption is large; 3. the noise is high, and the hearth is not designed for noise reduction in function, so that the hearth is not designed for noise reductionThe environment is greatly influenced in use, and the physical and psychological health of the human body is damaged.

The invention content is as follows: the invention aims to provide an energy-saving and efficient cooking hearth which has the advantages of high heat efficiency, low fuel consumption and low noise aiming at the defects of the cooking hearth in use.

The purpose of the invention can be realized by the following technical scheme: an energy-saving and high-efficiency cooking hearth comprises a whole hearth body and a mounting hole which is arranged at the lower end of the hearth body and connected with a furnace end, and is characterized in that an annular waste heat recovery cavity is arranged at the middle upper part in the whole hearth body, an annular pipeline for air supply or liquid fuel circulation is arranged in the waste heat recovery cavity, an interface connected with an external pipeline is arranged on the outer surface of the whole hearth body by the pipeline, a medium with good heat conductivity is filled between the waste heat recovery cavity and the pipeline arranged in the waste heat recovery cavity, and an annular heat insulation noise reduction material is arranged at the middle lower part in the whole hearth body.

The pipeline for gas fuel circulation refers to a gas pipeline and a combustion air pipeline, wherein the pipe diameter of the combustion air pipeline is larger than that of the gas pipeline.

In order to prevent the pipeline from being blocked and cannot be used, the pipeline for the liquid fuel to flow is provided with more than 2 liquid fuel pipelines.

The invention has the following effects: 1. the device is provided with an annular waste heat recovery cavity and an annular pipeline for air supply or liquid fuel circulation in the recovery cavity, and when the fuel at normal temperature flows through the pipeline, the fuel can absorb a large amount of waste heat in the hearth body to exchange heat so as to raise the temperature, so that the waste heat is effectively utilized, and the heat efficiency of the device is improved; 2. the combustion efficiency is high, the energy consumption is low, this lies in, the aforesaid normal temperature fuel absorbs a large amount of waste heat in the furnace body and promotes the temperature when flowing through the pipeline, thus can make them only need to heat in shorter time and enter the ignition to burn, has saved the energy that the normal temperature fuel is raised to the ignition temperature and consumed, thus achieve the combustion efficiency height, the energy consumption is low; 3. the device has low noise, is beneficial to environmental protection and physical and mental health protection of people, and is characterized in that the annular heat-insulating noise-reducing material is arranged at the middle lower part in the whole hearth body, not only has the function of preventing the waste heat of the hearth body from being dissipated, but also can better absorb the noise generated by the hearth body in the combustion process.
