Description

Heating copel with double lid structure {COOKER FOR HEATING FOOD HAVING A DOUBLE LID}

The present invention relates to a heat-generating copel having a double lid structure, and more specifically, to a heating copel having a double lid structure that can heat food from the front.

Currently, a variety of instant foods are emerging with convenience in mind, and disposable containers that allow for simple eating outdoors have been developed and various instant foods are being sold. In order to heat instant food, which is cooked by pouring hot water, a separate heating means such as a burner must be provided, but the use of such heating devices outdoors is restricted or prohibited due to the risk of fire.

When carrying heating equipment is difficult or prohibited, such as hiking, fishing, or outdoor activities, hot water must be carried and used in a thermos. There are problems such as the inconvenience of carrying a separate thermal container, and a time limit for warming when using a thermal container.

When the inner lid 280 and the outer lid 200 are combined, a lid space 261, which is a space through which water vapor can flow, can be provided due to the lid assembly 270 located between the inner lid 280 and the outer lid 200. The water vapor formed in the hydrothermal heating agent 10 flows into the lid space 261 along the plurality of steam grooves 120 formed in the outer container 100, and as a result, the upper part of the food located in the inner container 300 is covered with hot water vapor. It may become warm due to

The inner lid 280 has an inner lid 280 surface formed in a plate shape, and may be formed of one or more materials selected from the group consisting of aluminum, stainless steel, silver, iron, and copper, and may be formed of an inner container. The cross-sectional shape of 300 may be circular or polygonal.

The inner lid 280 is provided with an internal step 290 generated outward from the upper surface of the corner for engaging with the flange formed at the corner of the inner container 300, thereby allowing easy contact with the inner container 300. The inner container 300 can be closed by wrapping the inner container 300 without any gaps.

The central portion of the inner lid 280 has a protruding surface that protrudes upward from the surface of the plate-shaped outer lid 200 to engage the lid assembly 270, and the central portion of the inner lid 280 is formed with the lid assembly 270. ) can be combined with the lower surface of.

The inner lid 280 can optionally be provided with a plurality of filter holes 281, and is provided with a filter in the plurality of filter holes 281 to filter out magnesium and iron generated by the hydrothermal heating agent 10 reacting with water. Foreign substances are filtered out, and only clean water vapor is supplied to the inner container 300, so that the filtered water vapor can directly cook food located in the inner container 300.

The cross-sectional shape of the outer lid 200 may be circular or polygonal, and the material of the outer lid 200 may be made of one or more materials selected from the group of stainless steel, iron, plastic, and aluminum.

The outer lid 200 is located between the lower edge and the upper edge and may be provided with a silicone ring 250 that increases the bonding force of the heat-generating capel. As a result, water vapor flows into the outer lid 200 and the outer container (100). ), it can exit through the pressure valve 220 without escaping through the gap.

The lid handle 230, which is formed on part of the outer lid 200 and other parts and extends outward from the outer surface of the outer lid 200, can be selectively combined with the container handle 130, and is a handle protrusion formed in relief. Can be provided, so that the combination can be firmly fastened by combining with the handle engraving groove formed in the engraving on the container handle 130.

In addition, the lid handle 230 may be provided with a lid safety button that can securely fasten the connection and safely separate the outer lid 200 and the outer container 100, and when the button is pressed, the handle protrudes in combination with the lid safety button.
