The present invention relates to a device (1) for generating steam. The device (1) comprises a plate (2) forming a surface, and a heating element (3) to heat the plate (2) to a predetermined temperature being at least above water evaporation temperature. The plate (2) is inclined at an angle compared to the horizontal direction to define an upper end and a lower end. The device (1) also comprises a water inlet arrangement (4) for dispensing water onto the plate (2) proximate the upper end, a control unit (11) to control the flow of water dispensed onto the plate (2), and a scale collection container (5) disposed adjacent to the plate (2). The control unit (11) is configured to control the flow of water dispensed onto the plate (2) and the temperature of the plate (2) so that substantially all the water dispensed onto the plate (2) evaporates before it reaches the lower end (15) of the plate (2). This invention allows an easy scale collection, thanks to the inclination angle of the plate's surface that causes the dislodged scale to travel down the plate's surface toward the lower end of the plate and, ultimately, into the container.

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 spraying and re-heating vapor reactor includes: a heat preservation boiler; a vapor reaction boiler disposed in the heat preservation boiler; a re-heating conduit communicating the vapor reaction boiler with a device outside the heat preservation boiler, a high heat capacity material being accommodated within the heat preservation boiler, and surrounding the vapor reaction boiler and the re-heating conduit; a heater heating the high heat capacity material; a sprayer disposed in the vapor reaction boiler; and a liquid supplying tube communicating with the sprayer through structure walls of the heat preservation boiler and the vapor reaction boiler, and supplying an external liquid to the sprayer. The sprayer atomizes the external liquid into an atomized liquid absorbing thermal energy from the high heat capacity material and becomes a low-temperature vapor entering the re-heating conduit and being re-heated into a high-temperature vapor. A generator apparatus is also provided.

The present application relates to a system for generating steam, the system (1) comprising: a wall structure (3) forming a steam chamber (3A); an opening (4) formed in a wall portion (3B) of said wall structure (3); and a cover member (5) cooperating with said wall portion (3B) such that the cover member (5) can take a first position (P1) where the cover member (5) covers the opening (4) and a second position (P2) where the cover member (5) uncovers the opening (4); wherein said opening (4) has a cross-section surface being at least 50% of the cross-section surface of said wall portion (3B). The invention allows easy access to an inside part of the steam chamber (3A), thanks to the opening (4) provided in the wall portion (3B) of the steam chamber (3A), so that the user of the system (1) can clean the inside part of the steam chamber (3A) of scale.

The invention relates to a spray nozzle comprising an elastomeric tube (1) comprising a proximal end (7) through which a fluid is intended to enter said tube (1), and a distal end (8). The spray nozzle also comprises a slit (9) formed in the elastomeric tube (1) between the proximal end (7) and the distal end (8), for spraying the fluid out from the elastomeric tube (1). The elastomeric tube (1) includes a reinforcing element (10, 11) for limiting deformation of the elastomeric tube (1). By providing a slit in a tube between the proximal and distal ends of the tube, the slit can be sized to provide a broad spread pattern to the spray. The reinforcing element prevents over-expansion or deformation of the elastomeric tube.

The present application relates to apparatus for generating steam. It comprises a water inlet, a evaporation surface, and a heater disposed adjacent to the evaporation surface to heat the evaporation surface to a predetermined temperature such that water fed onto the evaporation surface via the water inlet forms a film on the evaporation surface and is evaporated. The apparatus is configured so that water is fed to one or more regions of the evaporation surface, and the temperature of the water fed onto the evaporation surface is lower than the predetermined temperature, so that scale on the or each region of the evaporation surface to which water is fed cools at a different rate at which water on a remainder of the evaporation surface cools. This causes scale on the evaporation surface to break apart and be dislodged from the evaporation surface.

A steam generator includes: a base module which has a water supply port for receiving steam water; and a steam module which is connected to an upper side of the base module, in which the steam module includes: a main body which has an upper surface and a lower surface; a flow pipe which is positioned at a central portion of the main body and into which the steam water flows; and a heater which supplies heat to the flow pipe, and in which another steam module is selectively coupled to an upper side of the steam module. According to this, the internal volume of the steam generator and the output of the heater provided in the steam generator can be selectively varied so as to provide an optimum output according to the volume of a cooking device in which the steam generator is installed.

The system further includes a power supply to power the heating tape to heat the inner heating tube to a temperature which can ignite the liquid fuel dripped onto the inner surface of the inner heating tube whereby there is an immediate combustion to form combustion products. Finally, the system includes an air line connected to the heating tube for directing compressed air through the inner heating tube to mix with the combustion products and transport the formed combustion aerosols out of an outlet end of the inner heating tube.
