Description

Kitchen range with fume exhausting function

Technical Field

The invention relates to the field of kitchen equipment, in particular to a stove with a smoke exhaust function.

Background

Along with the improvement of living standard of people, the improvement of living environment and the appearance of open type kitchen, the demand of consumers for products which are beautiful, convenient, safe, easy to clean, high in space utilization rate, especially high in planar area utilization rate is increasing day by day, and meanwhile, the appearance of open type kitchen and the density of urban residential buildings are improved, and products which can perform oil smoke purification treatment are urgent.

However, the existing gas cooking utensils basically adopt an external combustion and external pot support, are not beautiful in appearance, inconvenient to use, difficult to clean, unstable in pot placing, have certain potential safety hazards, and also have the problems of low space utilization rate, especially high utilization rate of plane area and the like, which cannot be effectively solved. Although some integrated cookers appear in recent years, open combustion heating and external pot supports are still adopted, along with popularization of the design concept of the integral kitchen, the integrated cooker adopts an independent module design, cannot meet the requirement of aesthetic design of the integral kitchen, cannot be recognized by consumers in a two-line city, and in addition, the smoke exhaust ventilator and the integrated cooker on the market do not adopt an oil smoke purification treatment technology, so that the oil smoke is directly exhausted outdoors, and great harm is caused to the atmospheric environment of the city. There are also problems with gas cookers, such as: the heat efficiency is not high, the waste gas carbon monoxide and nitrogen oxide produced in the combustion process are all discharged indoors, the wind resistance of small fire and low fire is weak, the existing gas furnace pot support is not stable when put in a pot, meanwhile, the existing gas furnace is inconvenient to clean, and especially the pot support and the liquid containing disc are difficult to clean. In addition, the pot support on the existing gas cooker occupies the whole plane area of the gas cooker, which is a great waste to the plane space, and especially the modern city presents the living environment of the small space of the big city, which is very important to the space utilization of every square meter in the room.

In addition, the non-open gas stove without the pot frame in the prior art is mainly characterized in that a heat-conducting panel is simply arranged above a burner, hot smoke generated by burning is directly diffused into air, and a plurality of defects exist in the use process. For example, the heat conduction efficiency of the heat conduction panel is low, the temperature of the cookware is slowly raised, the heat conduction cannot realize directional conveying, other areas of the panel of the cookware generate unnecessary high temperature, namely, the heat efficiency is seriously reduced, and on the other hand, operators are easily scalded and food materials or instruments are easily damaged.
