PROBLEM TO BE SOLVED: To constantly detect presence/absence of any cooking container on a trivet without being affected by boiling-over soup or the like.SOLUTION: When a cooking container is placed on a trivet, a rod is in a pushed-in state, and when the cooking container is displaced, the pushed-in rod is returned upwardly. The returning speed of the rod is delayed if the rod motion becomes irregular due to the effect of boiling-over soup or the like. Thus, by detecting the delay of the returning speed, it can be detected that the rod is hard to be returned, in other words, the rod is likely to be stuck. As a result, the possibility of generating any stick is removed in the stage before any stick occurs, and generation of any stick can be avoided. Thus, presence/absence of the cooking container on the trivet can be detected. |
