The present invention is intended to inform a user of a maintenance timing for a superheated steam generator. The present invention includes an induction heating type or electrically heating type superheated steam generation section and an informing section. The superheated steam generation section generates superheated steam by heating steam. The informing section transmits maintenance information by employing, as a parameter, an operating temperature of the superheated steam generation section and an operating time at the operating temperature.

The invention relates to an in-line heating device (100) for heating a fluid and/or a food product and/or a fluid foam and/or a food foam, the device (100) comprising a heating cartridge (120) and a primary heating unit (110). The heating cartridge (120) comprises an insert (121) made of an electrically conductive material and being inductively heatable by an oscillating magnetic field provided by the primary heating unit (110). The heating cartridge (120) further comprises an inner heating path (124) through which the fluid and/or food product and/or fluid foam and/or food foam circulates. The heating path (124) is arranged inside the insert (121) so that fluid is heated while circulating through the path (124) and before being delivered from the device (100).

The invention further relates to a foaming machine (200) providing a fluid foam and/or a food product foam, the machine being configured to receive an in-line heating device (100) as described. Still further, the invention relates to a system (300) for providing a hot fluid foam and/or a hot food product foam.

The present disclosure relates to a water-purifying device and a method for controlling the water-purifying device. In order to maintain a hot-water discharge temperature of water in the hot-water storage tank upon a hot-water discharge request from a user, an upper-limit temperature and lower-limit temperature corresponding to the hot-water discharge temperature are determined. Thus, the water-purifying device according to the present disclosure may drive a heating module thereof based on the upper-limit temperature and lower-limit temperature.

An electric water heater comprising two autonomous parts which are not in contact with each other: One part being a water tank having a plate of ferromagnetic material at its base, and the other part a magnetic induction module with variable control of power.

To operate the water heater, the induction module is coupled to the base of the water tank; the energy is released by magnetic induction from the induction module to the plate of ferromagnetic material at the base of the water heater, which gets hot, heating the water inside the water tank. The fact that the induction module is physically separated from the water tank means that the electricity cannot be in contact with water at any time, so that the safety of the water heater against electric shock is total.

The design allows several induction modules to be connected in parallel for water heaters requiring larger water tanks. A contactless temperature sensor of the water in the water tank ensures the total separation between water and electricity.

As the induction module features variable control of power, it allows either to limit the supply of electric power to the coil manually, or automatically switch the amount of electric power according to the needs of the user allowing for a great deal of programmability and electricity savings.

This invention provides a fluid heating device that is free from breakage even though a conductor tube is transformed due to being heated. Concretely, this invention is provided with an electrical connecting member that constitutes a short circuit by electrically connecting each of required portions of the conductor tube, and uses the electrical connecting member that is transformable in accordance with a transformation resulting from a temperature change of the conductor tube.

An induction coil assembly for an induction cooking hob has a coil winding, a lower electrically isolating sheet and optionally a thermally insulating sheet. The induction coil assembly further includes a carrier plate for supporting the lower electrically isolating sheet, the coil winding and the thermally insulating sheet. At least two power cables are provided for each coil winding. The power cables are at least partially arranged at a bottom side of the carrier plate and act as spring elements, so that the induction coil assembly can be pressed or is pressed against a glass ceramic panel of the induction cooking hob.
