To provide a drying and heating machine for a bathroom as improvement of a conventional technique using PTC heaters as a heating means involving such a problem that its opening/closing means for driving the load of each PTC heater repeats the opening and closing motions to result in a wear of the current feeding contact of the opening and closing means over a long period of service, which requires provision of a circuit to reduce the wear.

The drying and heating machine for the bathroom is composed of a plurality of PTC heaters in parallel connections, a first opening and closing means with which one-side ends of the heaters are connected commonly and which opens and closes them in the lump, a group of second opening and closing means to open and close the heaters individually, and a control means to control the closing operation of the opening and closing means, wherein the control means first closes the first opening and closing means, and then closes the group of the second opening and closing means each at prescribed time intervals.
