Inductive heating device for beverage can

Abstract

The present invention aims to provide an inductive heating device (4) for a beverage can with which the contents can be heated efficiently and with which the temperature of the contents can be measured precisely. The inductive heating device (4) for a beverage can has a can-holding body (6) that holds a metal beverage can (1) on the neck portion of which a threaded portion is formed, with a cap (3) being wound and tightened onto that threaded portion, and resealing of the beverage can being enabled by the cap (3), and an induction heating coil (9) being arranged at the outer periphery of the can-holding body (6). The can-holding body (6) is constructed such that the metal beverage can (1) is inserted and held with the cap (3) being protruded upward in the axial direction of the metal beverage can (1), and the heating coil (9) is arranged at the outer periphery of the can-holding body (6). The inductive heating device also is equipped with a temperature measurement means (10) that measures the surface temperature of the cap (3) when the metal beverage can (1) is inserted into the can-holding body (6).

Description

technical field [0001] The present invention relates to an induction heating device that heats a can filled with beverages by electromagnetic induction heating, and more particularly relates to an induction heating device that controls to stop heating when the detected surface temperature of the can reaches a set temperature. Background technique [0002] Currently, beverage can heat-retaining devices widely used in convenience stores and the like are configured to store a plurality of beverage cans inside a glass case or the like, and heat them to a predetermined temperature and keep them warm. Therefore, when a customer wants a hot beverage can, he takes out the desired beverage can from the thermal insulation device and purchases it. That is, with such a thermal insulation device, the internal atmosphere temperature of the inside of the glass case, etc. is heated to a predetermined temperature, and the beverage can is accommodated in the temperature atmosphere. There is ...

[0007] In addition, as in the induction heating device for beverage cans described in Japanese Patent No. 4562765, when a coil is provided on the outer circumference of the trunk of the airtight can to perform induction heating, if the temperature of the trunk is measured, it becomes a measurement heating unit. There is a possibility that there may be a difference between the temperature of the measurement location and the temperature of the contents in the vicinity of
