Description

Energy-gathering cover for stove and gas stove applying same

Technical Field

The invention belongs to the technical field of gas cookers, and relates to a kitchen energy-gathering cover and a gas cooker using the kitchen energy-gathering cover.

Background

In the actual use process of the existing gas stove, because a pot is placed on a pot support for heating, and a certain space interval is formed between the pot and a burner, the heat energy generated by gas combustion is used for heating the pot, and a considerable part of the heat energy is dissipated to the surrounding environment, so that energy waste is caused; in order to solve the above problems, in recent years, there have been some heat collecting and energy concentrating apparatuses in China, such as "an energy concentrating ring for a gas cooker and a gas cooker having the same" disclosed in chinese patent CN203404823U, and "an energy concentrating gas cooker" disclosed in chinese patent CN204042984U, the gas cooker also has an energy concentrating pan support, the energy concentrating ring structure can reduce the consumption of heat energy to a certain extent, improve the thermal efficiency of a burner, and can separate smoke from a secondary air supplement channel, for this reason, the energy concentrating ring is generally provided with a secondary air supplement channel for supplementing secondary air, such as "an energy concentrating ring for a gas cooker and a gas cooker having the same" disclosed in chinese patent ZL201320460471.1, which includes a first reflecting ring and a second reflecting ring that effectively increase the whole reflection and energy concentrating area of the energy concentrating ring, an air supplement channel is provided between the upper end of the first reflecting ring and the lower end of the second reflecting ring, the problem of insufficient air supplement in the gas combustion process can be solved by arranging the air supplement channel, in order to reduce CO emission, secondary air supplement is sufficient as far as possible and is often excessive, and the excessive secondary air supplement can take away a large part of heat energy generated by gas combustion; the energy gathering effect is realized by adding the energy gathering cover, and meanwhile, the mode of a smoke outlet (the height of the smoke outlet refers to the distance from the highest plane of the edge of the energy gathering cover to the bottom of a boiler, namely the effective height of the discharged smoke) can be reduced, if the height of the smoke outlet of the existing energy gathering cover is 10mm, the discharged smoke and heat are more, if the height of the smoke outlet is reduced to 6mm, the smoke cannot be smoothly discharged, the discharged smoke is correspondingly reduced, the smoke is gathered in the inner space from the bottom of the boiler to the energy gathering cover, so that the secondary air supplementary channel supplements secondary air resistance to be increased, the supplement cannot be carried out, the combustion is incomplete, the heat efficiency is reduced, and toxic and harmful gases such as carbon monoxide and the like can be generated; however, the secondary air supplement channel is too large, the secondary air is sucked more, and the heat taken away by the exhausted smoke is increased, so that the heat efficiency is low; the secondary air supplement channel is too small, and incomplete fuel gas and over-standard smoke emission are inevitably caused by insufficient secondary air supplement amount. In order to have good performance on efficiency and smoke emission of the gas stove under different user use environments, namely, on the premise of reducing a smoke outlet, secondary air with proper quantity can be supplemented, so that the combustion working condition is greatly influenced.
