Novel energy-saving, safe and environment-friendly gas cooker

Abstract

The invention discloses a novel gas cooker having obvious and efficient energy-saving property, environmental protection and safety. The novel gas cooker consists of a combustion chamber, a heat exchanger, a gas-distribution ignition switch, a gas mixing chamber, a chimney and a connecting pipe. The combustion chamber and a cooking utensil form a closed combustion space; the waste gas carrying heat energy cannot be discharged into a kitchen directly but flows into the heat exchanger along with a pipeline to perform heat exchange with newly-supplied air and fuel gas; the air and the fuel gas after heat energy absorption enter the gas-distribution ignition switch to perform gas distribution, then enter the gas mixing chamber and are fully mixed together, then the mixture enters the combustion chamber to perform combustion and heat release, and the waste gas after heat dissipation flows into the chimney along with the pipeline and is discharged out of a room. The novel gas cooker has an efficient heat energy utilization ratio, reduces the pollution to the air in the kitchen and the raise of the environment temperature and improves the quality of a working environment; besides, if the events of gas leakage or sudden flameout happen, as long as the cooking utensil is placed on the cooker, the leaked toxic fuel gas can be discharged out of the room to put and end to gas poisoning events.

Description

Technical field: [0001] The invention relates to a new type of gas cooker, in particular to a gas cooker with obvious high efficiency, energy saving, environmental protection and safety. Background technique: [0002] At present, all gas stoves used in households and on the market are open. The heat energy released after the combustion of gas (in this manual, natural gas and liquefied petroleum gas are collectively referred to as gas) is absorbed and utilized at one time. The exhaust air is discharged directly into the kitchen together. Such a gas stove has the following obvious disadvantages: 1. The utilization rate of heat energy is low, and a large amount of unabsorbed heat energy is directly dissipated in the air without being reabsorbed and reused; High indoor temperature in the kitchen deteriorates the working environment and endangers people's health; 3. If there is a gas leak or sudden extinguishment, the gas will be discharged directly into the house, which will ea...

Such a gas stove has the following obvious disadvantages: 1. The utilization rate of heat energy is low, and a large amount of unabsorbed heat energy is directly dissipated in the air without being reabsorbed and reused; High indoor temperature in the kitchen deteriorates the working environment and endangers people's health; 3. If there is a gas leak or sudden extinguishment, the gas will be discharged directly into the house, which is likely to cause gas poisoning, threaten life safety, and reduce the safety of use
