A fixedly positioned hot plate, particularly for use with a coffee maker, has an upper surface for receiving a container of liquid to be maintained at a constant temperature. An electric heating device arranged underneath the hot plate includes a plate member movable between a first position in biased engagement with the underside of the hot plate and a second position spaced therefrom to vary the heat exchange rate therebetween. Secured to the underside of the plate member is a metallic sheathed heating having a water heating pipe soldered to the periphery thereof. A temperature sensitive element, e.g. U-shaped bimetal, thermally coupled to the heating device has a first portion connected to a downwardly dependent stud secured to the underside of the hot plate and extending freely through a bore in the plate member an a second portion secured to the plate member. The temperature sensitive element is arranged to move the plate member toward and away from the hot plate in response to the temperature of the heating device to maintain the temperature of the liquid in the container at constant optimal value independent of the amount of liquid in the container.

An ironing device which comprises an unheated soleplate, a fan, and a discharge port in the soleplate. The fan generates an air stream which is conveyed via the discharge port between the soleplate and a textile material. A large surface and supporting air cushion is developed between the soleplate and the textile material.
