Abstract: The invention concerns a forced convection gas oven wherein a globally parallelepiped muffle chamber contains a centrifugal convection turbine driven by a motor and arranged adjacent to the center of the rear peripheral wall. A gas burner is arranged coaxially upstream of the turbine, the assembly being surrounded by a mechanical protection grid. The gas burner is annular in shape and is oriented towards the center of the convection turbine. The oven is thus provided both with a better performance and a better distribution of cooking heat.

Abstract: The invention concerns an oven wherein a globally parallelepiped muffle chamber (1) contains a centrifugal convection turbine (9) driven by a motor (10) and arranged adjacent to the center of the rear peripheral wall (7). Annular electrical resistors (12, 13) are placed at the periphery of the turbine, the assembly being surrounded by a mechanical protection grid (22). The convection turbine (9) and the heating means (12, 13) are placed in the muffle chamber (1) communicating directly with the cooking volume (81), without separating wall countering the air flow. The oven is thus provided both with self-cleaning effect and a better cooking heat distribution in the oven.

Abstract: Meals are placed on individual trays in an institutional kitchen. The individual trays have a first part carrying the meal portion intended to be eaten hot and covered with a thermally insulative cloche and a second part carrying the meal portion intended to be eaten cold. The individual trays are transported in a thermally insulated enclosure to the places where the meals are to be eaten, where they are distributed into local individual units having a thermally insulated enclosure. Each individual unit includes retractable contact terminals operated by an electromagnet and contacting external terminals on the cloche which are in turn electrically connected to an electrical heating element of the cloche. Accordingly, by supplying power to the contact terminals, the meal portions intended to be eaten hot and placed under the cloches are selectively heated. The device is relatively inexpensive and facilitates meal handlings in compliance with hygiene conditions.

Abstract: In a steam oven suitable for cooking foods, for example, with a fixed distributor for the water to be evaporated, air is aspirated to form a central flow of aspirated air by a cylindrical fan and is discharged radially at the periphery toward heating elements. Water is fed into the interior of the fan by an inlet pipe and distributed in the depthwise direction of the fan by a distributor structure including a pipe end section having a lateral slot and a fixed inclined distributor plate. The invention applies to steam oven suitable for cooking foods, and assures good distribution of the water over all the heating elements so that it is evaporated.

Abstract: A tray for warming food has a tray body of double cup shape formed of a plastics material base structure with an aluminum top diffusion layer attached to the base structure in the part to receive a cloche. The cloche has a plastics material outer jacket fastened to an aluminum bottom diffusion layer in contact with an intermediate member made of a material that can be heated by magnetic induction. The top diffusion layer of the tray body comes into contact with the bottom diffusion layer of the cloche at the periphery of the interior space along peripheral contact rims. This provides a meal tray assuring fast heating of food placed in the interior space of the first part, the second part being intended to carry food that is to remain cold.

Abstract: A convection steam oven includes an enclosure with a fan for circulating air and heating elements downstream of the fan. An inlet pipe conducts water from a water supply to an outlet orifice directing a jet of water onto a spray cone that throws the water onto the fins of the fan and onto the heating elements. The inlet pipe includes a water flowrate regulator device including a watertight storage tank, an overflow pipe and a vent pipe. A solenoid valve controlled by a timer is provided upstream of the storage tank.

Abstract: An oven door locking device includes a male rod fixed to the door and entering a female member fixed to the oven muffle. The female member includes locking members movable radially to engage in an intermediate groove on the male rod when the door is closed. The oven is unlocked by operating a push-button which pushes an internal bearing ring against an unlocking ring which withdraws the locking members from the internal bore of the female member in order to remove them from the groove in the male rod.

Abstract: An oven for cooking foodstuffs includes an airtight enclosure having an opening closed by a door. Water condensing in the enclosure is collected in the lower part of the enclosure and discharged into discharge pipes. An excess steam circuit captures excess steam escaping from the enclosure and feeds the captured steam to a treatment system including a steam condenser to convert it into liquid condensates. The liquid condensates are collected and discharged into discharge pipes. At least one heater heats steam passing through it in the excess steam circuit on the upstream side or on the downstream side of the steam condenser.

Abstract: A boiler for the production of steam and/or hot water has a principal enclosure limited by a watertight wall for containing water, a bottom water extraction outlet,a water supply inlet, an upper steam outlet and a level detector controlling the water level in the enclosure. Electric immersion heating elements are provided in the enclosure for heating the water to generate steam. At least one section of the enclosure wall adjacent the water level on which scale deposits are likely to form is deformable by flexion and is stressed by time-varying deformations of the wall produced by variations of water and/or steam pressure in the enclosure which causes the film of scale deposited on the inner surface of the at least one deformable section to break up and become detached so that they fall to the bottom of the enclosure for easy elimination by drainage of the water from the enclosure through the bottom water extraction outlet.

Abstract: The steam generator according to the invention consists of a main vessel 1 equipped with heating devices 12 controlled by control devices 13. The water level in the steam generator is kept at an average level 5 by control devices 13 which control a water inlet solenoid valve 10. Measurement of the average water level 5 is achieved by a pressure switch 20 that is exposed to the pressure inside a measuring vessel 18 that communicates with the main vessel 1 via a lower measuring opening 22. Balancing pipework 34 links the pressure switch 20 to the pressure of the steam produced in the steam generator. Pressure switch 20 generates measuring signals that are sent via conductors 17 to control devices 13 in order to actuate solenoid valve 10.

Abstract: A steam generator is disclosed for a cooking apparatus, having an intermediate duct admitting discharge water into the lowest central portion of the enclosure of the generator, and connected to a vane pump whose outlet feeds into an outlet duct rising as far as an upper bend then descending as far as an emptying duct. Heating tubes cause vaporization of the water which they contain and the steam escapes through a horizontal upper duct then a steam conduction duct. The generator applies in particular to ovens for cooking food.

Abstract: A steam generator for cooking appliances, having three vertical tubes connecting a lower duct and an upper duct together. The central tube is a heating tube having an electric resistance welded to the outside of the tube. The second tube is a return tube for returning water from the upper duct to the lower duct. The steam escapes through a discharge orifice in the upper duct. The third tube comprises a resistive probe measuring the level of the water and for regulating it to an intermediate level.
