High frequency heating apparatus having steam generating function

摘要

A high frequency heating apparatus having a steam generating function including a heater main body 111 embedded with heater 27 , a transport tube heating portion 113 for boiling a liquid in a transport tube 112 , and a heat conduction control portion 114 comprising a material having a heat conductivity smaller than a heat conductivity of a material forming an evaporating portion 25 and capable of restraining adherence of scale in accordance with local boiling in the transport tube by reducing an amount of heat conducted to the transport tube 112 while ensuring heat energy supplied to an evaporating side by setting heater to a high temperature. Further, a steam supply mechanism for excellently maintaining a balance of supply of the heat energy to a side of a transport portion and a side of an evaporating portion and continuously generating steam at a high temperature near to 100° C. can be provided.
