AI Technical Summary

Technical Problem

Conventional food and drink heating devices using microwaves face a temperature disparity between the food and drink directly heated and the container indirectly heated, leading to the risk of overheating the food and drink if heating is controlled based on the container's temperature.

Method used

The device incorporates a microwave heating means in a heating chamber with a temperature checking mechanism that detects the temperature of a microwave-absorbing heating element. This element raises and maintains the temperature at a specified stop temperature, allowing the heating means to be controlled based on the heating element's temperature rather than the container's.

Benefits of technology

This approach ensures that the food and drink are heated accurately and safely, preventing overheating by controlling the heating based on the directly heated element's temperature, rather than relying on the indirectly heated container's temperature.

Abstract

To solve the problem that in conventional food and drink heating devices, heating is controlled based on a temperature of a container, so there is a risk that driving of heating means cannot be controlled well in accordance with food and drink.SOLUTION: A food and drink heating device (1) is provided with heating means (20) using microwaves in a heating chamber (13) in which a container (23) storing food and drink is placed, and heats food and drink with microwaves, where the heating chamber (13) is provided with temperature measurement means (21) for detecting temperature, the temperature measurement means (21) detects a temperature of a heating element (31) made of a raw material that absorbs microwaves to increase temperature and stops increase in temperature at a predetermined temperature (temperature increase stop temperature), and the heating means (20) is controlled based on the detected temperature.SELECTED DRAWING: Figure 4
