A steam generating container A heated by a heat source includes: a water evaporation chamber into which water is supplied by a water supply device; a leading opening to lead steam from the water evaporation chamber, and ejection openings ejecting steam led through the leading opening into a heating chamber containing food. A buffer chamber connecting through the leading opening and with the ejection openings is provided between the water evaporation chamber and the heating chamber. Even when bumping water enters the buffer chamber through the leading opening, the bumping water having entered flows inside the buffer chamber. Thus, the bumping water is hardly ejected into the heating chamber through the ejection openings.

A device for converting a liquid into vapor includes an enclosure, a heating surface with a downward slope arranged in the enclosure, and a liquid inlet port connected to an upper portion of the heating surface so that a liquid introduced from the liquid inlet port flows on the heating surface. The device also includes a vapor outlet port formed through a wall of the enclosure. The heating surface includes a heat transfer pipe configured to allow the flowing of a heat transfer fluid to heat the heating surface, and a corner piece including a U-shaped cross-section with a semi-circular portion arranged around the heat transfer pipe and an upper portion forming an opening on the enclosure.

A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including a tubular liner wetted with a curable compound; introducing fluid into the inflatable bladder to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition; measuring a flow rate and a temperature of the fluid entering the bladder; calculating a time period sufficient for the tubular liner to cure based on: an amount of heat required for curing, based on dimensional information of the liner, and the measured flow rate and temperature of the fluid; and maintaining the liner assembly in an inflated condition for the time period sufficient for the tubular liner to cure.

A steam generator comprises a water storage chamber which stores water, a steam generating heater which heats water in the water storage chamber, a water supply pump which supplies water stored in a water supply tank through a water supply port provided in the water storage chamber and a water supply passage, a discharge passage which discharges water formed with a first water discharge passage having a U shape to be convex downward, which is in fluid communication with a discharge port provided in the water storage chamber, and a second water discharge passage having an inverted U shape to be convex upward, and configured such that water stored in the water storage chamber is discharged through the discharge port and the water discharge passage according to the theory of a siphon, wherein the first water discharge passage is formed by a nonmetallic material.

A steam generator for use with a liner assembly for pipeline repair or reinforcement, includes: a water heater configured to heat water to generate steam; a water feed conduit configured to convey water to the water heater; an air heater configured to generate heated air; an air supply conduit configured to convey pressurized air to the air heater; a heated air supply conduit configured to convey heated air from the air heater to the water heater to yield a steam-air mixture; and an output conduit configured to convey the steam-air mixture from the water heater. An automated steam generator system including the steam generator is also described.

An electronic cooking apparatus having a steam supply device for supplying steam to a cooking chamber of an oven is provided. The electronic cooking apparatus may include a steam generating device including a steam supply portion that generates steam and supplies the steam to a cooking chamber, and a water level sensing module that senses a level of water inside of the steam supply portion using a low water level sensor and a high water level sensor. In addition, the electronic cooking apparatus may include a water supply pump that supplies water from a water tank to the steam supply portion; a drain pump that collects condensed water from the steam supply portion to the water tank; and a controller that controls on/off operations of the water supply pump or the drain pump according to a change in the level of water in the steam supply portion sensed by the water level sensing module.

The present invention relates to bathing devices for special therapeutic or hygienic purposes such as e.g. sauna or Finnish baths, and especially to a steam generator element for a sauna electric heater and a sauna electric heater. A sauna electric heater (13) according to the present invention comprises comprising a frame part (14), heating resistor elements (15-17), (29), (30), (54), (55) inside the said frame part (14), and sauna stones (2) arranged inside the said frame part (14) and/or on the top part of the said sauna electric heater (13), which said sauna electric heater (13) comprises a steam generator element (18), (19), (26), (33), (37), (45), (52), (62) placed inside the said frame part (14) between at least two heating resistor elements (15-17), (29), (30), (54), (55) and/or said sauna stones (2), said steam generator element (18), (19), (26), (33), (37), (45), (52), (62) comprising a water tank (20), (27), (38), (46), (53) fillable with water. The sauna electric heater according to the present invention provides more durable operation and with less generated faults and brake ups when compared to the prior art solutions.

A steam cleaning apparatus comprising: a main body having a boiler and a pump; a main power switch; a cleaning head coupled to a main body through a joint; a yoke in the main body or the cleaning head, the yoke having an arm contacting a position sensitive switch so that when the main body is in a non-use position, the position sensitive switch prevents the main switch from supplying power, and when the main body is in an in-use position, the position sensitive switch allows the main switch to provide power.

A steam generator including a heating chamber for heating water to generate steam, with a sidewall of the heating chamber being a heating element. The steam generator may be installed in an appliance, and may be removably installed in the appliance.

An extraction cleaner includes a steam delivery system, a liquid delivery system, and a recovery system, and includes multiple cleaning modes, including a first cleaning mode in which components of the steam delivery system, liquid delivery system, and recovery system are active, a second cleaning mode in which components of the delivery system and recovery system are active, and a third cleaning mode in which components of the steam delivery system are active. Methods for operating an extraction cleaner are also provided.
