Description

{DOUBLE-BOTTOMED COOKER FOR INDUCTION HEATER}

The present invention relates to a double floor cooking vessel which can be used as an induction heater using an induction current generated by a magnetic field as a heat source. More particularly, the present invention relates to a double floor cooking vessel capable of uniform heating in a cooking vessel through a double bottom .

A thin disc-shaped heat storage plate having a bottom plate with a peripheral wall attached to the bottom of the container body and a far infrared radiation powder such as a jade powder penetrated into the space between the container body and the bottom plate, It is known to be embedded. This double bottom cooking vessel is welded to the bottom of the container body through the peripheral wall of the bottom plate. In this type of double floor cooking vessel, there is a space between the bottom portion of the container body and the bottom plate when used in a general heater, and a heat storage plate is disposed in such space to increase the heating efficiency, There is an advantage in that the cooked contents are hardly pressed or burned by the indirect indirect heat.

Meanwhile, when the temperature of the induction heater used for cooking and heating the home is increased and the temperature of the cooking vessel rises above a predetermined cooking temperature, the induction current is stopped by the control circuit, It is possible to prevent the contents from being overheated. For this purpose, for example, a temperature sensor for detecting the bottom surface temperature of the cooking container is used as the induction heater.

When a general metal cooking vessel other than the double bottom is used for the induction heater, the bottom surface of the cooking vessel is placed on the upper plate portion of the induction heater so that the bottom surface of the cooking vessel is almost in contact with the surface of the induction heater and the temperature sensor detects the temperature of the bottom surface of the cooking vessel heated by the induction heater If the detected temperature is higher than the predetermined temperature, the heating is stopped.

However, when a cooking vessel having a double bottom and having a space for accommodating the heat accumulating plate inside the double bottom is used for the induction heater, the bottom surface temperature of the container body for substantially heating the cooking contents is set to the temperature sensor of the induction heater The bottom surface temperature of the bottom plate of the cooking container placed in contact with the top plate portion of the induction heater is detected and the heating operation of the induction heater is stopped when the bottom surface temperature reaches a predetermined temperature, The bottom portion of the container body, which is separated from the cooking cavity, does not yet reach a sufficient cooking temperature, so incomplete cooking can be achieved.

In order to solve the incomplete and uneven heating problem of such a double bottom cooking vessel used in an induction heater, it is necessary to heat by induction heating in the same condition at the bottom portion of the inner base of the double bottom cooking vessel and the bottom portion of the outer vessel Should be considered.

In the present invention, the present invention has been made in view of the above points, and it is an object of the present invention to provide a double floor cooking vessel which can be used as an induction heater using an induction current generated by a magnetic field as a heat source, And to provide a double bottom cooking vessel in which heating can be performed.

For this purpose, in the present invention, a stainless steel outer container having an inner bottom surface made of stainless steel having a bottom surface and an outer bottom surface disposed at a certain distance from the inner bottom surface of the inner container to form an annular inner space A donut-shaped heat storage plate in which far-infrared radiation powder is accommodated is disposed in an annular inner space formed between an inner bottom surface of the inner container and an outer bottom surface of the outer container, The present invention provides a double bottomed cooking container for an induction heater for an induction heater, wherein an upwardly recessed portion formed by an upwardly recessed central portion of the outer bottom surface of the outer container is disposed near the inner bottom surface of the container through a central portion of the heat storage plate, Between the inner bottom surface of the content container and the upwardly inserted portion formed on the outer bottom surface of the outer container in the central portion of the donut-shaped heat storage plate, Placed in the middle of the circular plate being nyumje, and the inner bottom surface of the information, the group of stainless steel, and the intermediate discs of the aluminum, characterized in that the contact face upwardly concave portion of the stainless steel outer vessel connected by brazing welding.
