Abstract
The invention provides a gas-cooker energy-saving cover. The gas-cooker energy-saving cover comprises a ceramic cover body. The ceramic cover body mainly comprises an annular ceramic outer wall and an annular ceramic inner inclined plane. The annular ceramic inner inclined plane is located inside the annular ceramic outer wall, the outer edge of the annular ceramic outer wall is connected to the upper edge of the annular ceramic inner inclined plane, and the annular ceramic outer wall and the annular ceramic inner inclined plane form a thermal insulation cavity at the bottom of the ceramic cover body. The upper surface of the annular ceramic inner inclined plane is provided with raised pot-support parts distributed in a ring array way, and the raised pot-support parts, the annular ceramic outer wall and the annular ceramic inner inclined plane are molded integratedly. The gas-cooker energy-saving cover can produce good fire gathering and windproof effects on a furnace head of the gas-cooker, can effectively accumulate radiation heat as energy for heating a pot, saves energy, is environmentally friendly and beautiful, and has a long service life. The thermal insulation cavity reduces transmission of heat to the annular ceramic outer wall, has thermal insulation effects, and avoids burns of the annular ceramic outer wall. The ring raised flame-blocking stripes can inhibit flame development so that the use environment of the gas-cooker is more comfortable.
