Abstract

PROBLEM TO BE SOLVED: To accomplish a heating with a higher heat efficiency without charring a heating section by providing a heating coil for induction heating of a heat exchange element by generating a high frequency magnetic field and a temperature control section to control the operation of a high frequency power supply means based on information of a temperature detection means. SOLUTION: When a start switch is depressed, a temperature control section 6 starts operation to compute a difference between the temperature detected of a temperature detecting means 7 and the temperature specified by a user and selects a necessary power from setting stored previously in an ROM. Subsequently, a high frequency power supply means 5 is driven to supply the power selected to a heating coil 4. A high frequency magnetic field thus generated works to perform an induction heating of a heat exchange element 3 made up of a magnetic body and the water heated is circulated to the bathtub 2 with a circulation path 1 so that the water in the bathtub 2 reaches a specified temperature. This prevents the charring of a heating section and also enables heating with a higher heat efficiency.

The operation of this embodiment will be described below. When a start switch (not shown) is pressed, the temperature controller 6 starts its operation. That is, the difference between the temperature detected by the temperature detecting means 7 and the temperature instructed by the user (for example, 42 ° C.) is calculated, and the required power is selected from the settings stored in the ROM in advance. Then, the high frequency power supply means 5 is driven to supply the selected power (for example, 1 kW) to the heating coil 4. In this way, the heating coil 5 generates a high frequency magnetic field, and the generated high frequency magnetic field inductively heats the heat exchange element 3 made of a magnetic material. That is, an eddy current is generated inside the heat exchange element 3 by the high frequency magnetic field, and heat is generated by Joule heat due to this eddy current. The water exchanges between the heat exchange element 3 and the water by passing the water through a large number of holes of the metal portion which are heated to a high temperature by this heat generation. The water heated by the heat exchange element 3 circulates between the bath 2 and the bath 2 through the circulation path 1, and the water in the bath 2 reaches 42 ° C. After reaching the predetermined temperature in this way, the temperature control unit 6 drives the high frequency power supply means 5 in the heat retention mode to operate so as to always maintain the predetermined 42 ° C. even when the hot water is cooled or water is added. To do.
