Multifunctional lightweight energy saving cooker

The utility model relates to a multifunctional lightweight energy-saving cooker which is favorable for bulk production. Thermal insulation cellucotton or other lightweight thermal insulation materials are adopted to manufacture the thermal insulation layer of a cooker body, a thermal insulation cover, the outer layer of a steaming grid and a thermal insulation base of the existing internal heating type cooker. The thermal insulation cellucotton or other lightweight thermal insulation materials are designed, processed, formed, assembled and produced according to the requirement of the interlayer shape of the thermal insulation layer on the four components of the energy-saving cooker. The energy-saving cooker can be divided into a plurality of grids or have no grid. The utility model can have a plurality of covers or just one cooker cover. The cooking time is short when the multifunctional lightweight energy-saving cooker is adopted, and the energy can be saved by 30 to 50%.
