Energy-saving cookware

Abstract

This invention provides an energy-saving cookware comprising a container, an overflow-prevention ring located on the outer edge of the container's bottom, and a plurality of densely arranged metal pillars on the bottom. The overflow-prevention ring has multiple perforations and forms a baffle structure in the direction away from the bottom. This allows the bottom to form a high-density metal array, enhancing the capture of external heat sources and significantly increasing the surface area for absorbing flame heat, thereby improving heat conduction efficiency and shortening cooking time. Simultaneously, the overflow-prevention ring can enclose the heat source and maintain stable convection, and can also guide overflowing soup or oil to drip directly, preventing liquid from adhering to the metal pillars and causing carbonization and failure.

Claims

1. An energy-saving cookware, comprising: A container having an internal accommodating space; an overflow prevention ring comprising a body having a connecting side and a supporting side, the overflow prevention ring being disposed on the outside of a bottom of the container with the connecting side, and the supporting side being formed by the body extending away from the bottom, such that the body has an annular structure and surrounds a region on the outside of the bottom, and the body having a plurality of perforations spaced apart and communicating with the region; and a plurality of metal pillars disposed on the outside of the bottom of the container and located in the region surrounded by the body, each metal pillar comprising a base connected to the bottom and a pillar extending from the base away from the bottom.

2. The energy-saving cookware as described in claim 1, wherein, The overflow prevention ring and the bottom of the container are welded together to form a single unit.

3. The energy-saving cookware as described in claim 1, wherein, The overflow containment ring extends outward from the bottom of the container and is integrally formed.

4. The energy-saving cookware as described in claim 1, wherein, The metal columns are arranged in a circular and / or honeycomb pattern.

5. The energy-saving cookware as described in claim 1 or 4, wherein, The distance between the bases of two adjacent metal columns is greater than or equal to 1 mm and less than 2 mm.

6. The energy-saving cookware as described in claim 1 or 4, wherein, The distance between the two adjacent metal pillars is greater than or equal to 4 mm and less than 5 mm.

7. The energy-saving cookware as described in claim 1, wherein, The cross-sectional area of ​​each metal column is smaller than the cross-sectional area of ​​the base.

8. The energy-saving cookware as described in claim 1, wherein, The total extension height of the overflow containment ring is greater than or equal to 2.5 cm.

9. The energy-saving cookware as described in claim 1, wherein, The distance between the axis of these perforations and the outer surface of the bottom is greater than or equal to 5 millimeters (mm).

10. The energy-saving cookware as described in claim 1, wherein, The distance between two adjacent perforations is less than or equal to 5 cm and greater than 3 cm.

11. The energy-saving cookware as described in claim 1, wherein, The total height of the overflow containment ring extending outward from the bottom is greater than the total height of the metal pillars.
