A centrifugal pump for household appliances comprising a cover () having:&#x2014;a first face internal to the pump adapted to be in contact with an operating fluid, and a second face external to the pump, opposite to the first face and provided with an annular groove () forming a projection inwards of the pump,&#x2014;a heating element () fixed in the annular groove (),&#x2014;a first support element () arranged on the second face and provided with a first constraint () adapted to be fixed to a first safety device (), said first support element () being in thermal contact with said operating fluid, whereby the first safety device () is adapted to come in thermal contact with the operating fluid,&#x2014;a second support element () arranged on the second face, distinct from the first support element () and provided with a second constraint () adapted to be fixed to a second safety device (), said second support element () being in thermal contact with said heating element (), whereby the second safety device () is adapted to come in thermal contact with the heating element ().

Heater for household appliances

Steam generator () is provided with an electric heating element () for heating water to be evaporated, consisting of an electric heating resistor () inserted in a profiled base () of a metal supporting element (), fixed in a hole obtained in one of the vertical walls () of the container () for heating water.

Steam generator

Electric air heater, in particular for electrical domestic appliances, comprising at least one heating element () provided with an insulated supporting element () on which at least one resistance wire () is wound. An electrical connector () clamps, with at least one electrical pin (), said at least one heating element (), tapping at least one end of said resistance wire (). The electrical connections of a thermostat () and/or a thermistor () are made by means of electrical tracks () formed directly on a surface () of housing () to which said thermostat () and/or thermistor () are attached. Said electrical connector () clamps said surface () with at least one further electrical pin.

Electric air heater, in particular for electrical domestic appliances

A home laundry machine () having an outer casing () and, inside said casing (), a laundry container () for housing the laundry to be dried, and a steam generator () for feeding a given amount of steam into the laundry container (), and which in turn has a tubular vaporizer () containing a given amount of water; a heater () for boiling and converting the water in said tubular vaporizer () into steam; and a steam exhaust pipe () for feeding the steam produced in the tubular vaporizer () into the laundry container (), and which has at least one tubular portion () contacting the heater (), so that the steam flowing along the tubular portion () receives a certain amount of heat from said heater ().

Laundry treatment machine

An electric radiant hotplate includes a base of electrically insulating material and a peripheral crown extending along the outer rim of the base and projecting upwards. A strip of resistive material is inserted in the base and is formed by a sequence of planar lengths and curved lengths connected to respective planar appendices that are inserted in the insulating base. The appendices can be connected to the planar lengths by respective peduncles applied on to the same side edge of the flat strip of resistive material. The appendices can also be either coplanar or not coplanar to the planar lengths and include a first portion connected to the respective planar length of the strip, and at least a second planar portion that is not coplanar with the first portion and is joined to the first portion via a rectilinear border, the first portions being applied on a same side edge of the flat strip of resistive material.
