Description

 Heating container for induction cooker

 Technical field

 The invention relates to a special drinking utensil for heating an electromagnetic oven. Background technique

 The induction cooker is a very convenient heating device with high thermal efficiency and safety. The principle is that an electromagnetic coil is installed in the induction cooker, and the electromagnetic coil is connected to the power supply at both ends; after the electromagnetic coil is energized, a magnetic line is generated around the electromagnetic coil, and the magnetic line forms a vortex at the bottom of the heating device to generate heat, and the food in the appliance is heated to realize Smokeless, dust-free cooking and cooking, the heating form is different from electric stoves, gas stoves, etc. There are many electromagnetic tea stoves, which are composed of an induction cooker and an iron teapot. The drinking utensils are only those that require the teapot to be made of iron and can be electromagnetically heated. There is also a special purple clay crucible for induction cooker, which is based on the structure of the existing purple clay crucible, and a stainless steel disc is inlaid or fastened at the bottom of the crucible body cavity. In this way, when the purple sand enamel is placed on the induction cooker to process the food, the coil of the ceramic plate under the induction cooker generates a magnetic flux to pass through the stainless steel disk in the purple sand sputum to generate eddy current, so that the bottom of the pan is rapidly heated to achieve the purpose of heating the food. The above designs are all novel, but the characteristics of electromagnetic induction of the electromagnet are not well utilized, and a special cooker for the induction cooker is manufactured. Summary of the invention

 The object of the present invention is to design a special cooker for an induction cooker to heat the food in the drinking utensil according to the heating characteristics of the induction cooker, and to heat the drinking utensils, thus saving the drinking utensils.

 The induction cooker heating container of the invention comprises a container body and a lid, the container body having a heat insulating structure or a heat insulating material, and a heating body provided with a ferromagnetic material in the inner layer of the container. The specific position of the heating body may be provided at the bottom of the container body or at the side wall of the container body. The container is placed on an induction cooker, and after being energized, electromagnetic waves are passed through the container to generate eddy currents on the ferromagnetic material in the container to be heated, and the heating body exchanges heat with the food in the container to heat the cooked food. Since the container is kept warm, that is, the amount of heat dissipated during the heating process is small, the energy consumption is low, and secondly, after the cooking is completed, the container is kept warm without heating.

 The insulated structure of the container may be double-walled with a hollow wall between the two walls.

 The container lid may be designed with a heat insulating structure or a heat insulating material, or may not have a heat insulating function.

 The heat preservation structure of the container is designed as an insulation layer, and the outer layer of the container is covered with a heat insulating material for heat preservation.

 The heat insulating container is provided with a heating body or a container inner wall made of a ferromagnetic material having a Curie point in accordance with a selected heating temperature. Use of this material on an induction cooker When the heating temperature reaches the Curie point of the heating body, the heating body of the ferromagnetic material loses its magnetic properties and naturally cannot continue to heat the food in the container.

The electromagnetic heating and heat preservation container of the invention adopts a heating body made of a ferromagnetic material The container is placed in the body of a container made of a non-ferromagnetic material, and the container is made into an insulated container by the non-contact characteristics of electromagnetic heating. When the heating body made of ferromagnetic material is disposed on the outer surface of the container body, since the ferromagnetic material has high thermal conductivity, not only the heat of the heat source during heating is quickly lost, the heat utilization is low, and the container has no heat preservation property, such as The existing electromagnetic heating teapot maintains the water in a boiling state by continuous electromagnetic heating. When the water temperature is lower than the set temperature, the electric control device is heated by the hot water bottle, so that not only the power consumption is large, but also the water is continuously reheated. The water quality will be affected, and the container of the present invention is used. After the water temperature in the kettle is heated to boiling water, the kettle is kept warm without heating, energy saving, and the water is not always heated to affect the quality of the water.

 The heat insulating electromagnetic heating container of the present invention, the container body made of a ferromagnetic material having a Curie point and a selected heating temperature, or a heating body provided in a container body made of a non-ferromagnetic material, each container having A fixed maximum electromagnetic heating temperature, once this maximum electromagnetic heating temperature is reached, the ferromagnetic material loses its magnetic properties and cannot continue to heat the food in the container. The electromagnetic kettle thus manufactured does not need to be provided with a temperature sensing and control device. For example, in such a container for a fryer, the temperature is not excessively excessive, and the phenomenon of frying and frying is not caused. BRIEF DESCRIPTION OF THE DRAWINGS:
