Abstract
The shaver warmer of this invention includes a heat transfer portion which almost closely fits the shaver head of the electric shaver to be warmed. A heat supply portion is directly connected to the heat transfer portion and a temperature control portion controls the heating temperature by detecting the temperature of the heat transfer portion. The shaving head of the electric shaver can thereby be heated to a predetermined temperature in a relatively short time so that advantage may be taken of the relatively large thermal capacity of the shaving head of an electric shaver.
