Definitions
- the present invention relates to a cooking oven comprising a cavity and a separating and insulating plate which can be inserted horizontally in the cavity in order to split it in two sub-cavities, each sub-cavity having at least a heating element on its side wall.
- an oven of the above type which has a reduced cost, while maintaining the same flexibility in use, improved quality of cooking, better cleanability by means of a flexible heating system using heating elements placed either horizontally (top and bottom walls) and/or vertically (side walls).
- the oven comprises heating elements placed vertically on side walls of the cavity and attached to the external face of the cavity wall, in addition to traditional heating elements placed horizontally on top, bottom and rear walls.
- the concept is applicable to pyrolitic and non-pyrolitic ovens, and includes also the solution according to which the oven cavity does not have the traditional heating elements placed horizontally on top and/or bottom walls, and/or the solution according to which the oven cavity is provided, on back wall thereof, with a traditional central forced air fan and a heater, which can be a circular or non circular tubular heater or a quartz lamp.
- tubular heating elements two for each side of the oven cavity, are housed in suitable metal casings or 'pockets' that are attached to the external face of the cavity wall.
- the cavity (when the separating plate is removed) does not distinguish, in a visual inspection, from a cavity of a traditional oven.
- the oven cavity can be provided with openings closed by metal plates that cover the heater elements. In this case it is preferred to use for such plates a material different from the material of the oven walls, in order to improve and optimise heat transfer from the heating elements to the oven cavity.
- a twin radiant heating element is mounted behind the metal side wall or behind a metallic or ceramic glass plate and is located at the centre of each side wall of the oven.
- the heaters are aligned so as to transfer heat also to the separating and insulating plate faces, underneath the food tray or container as well as to the cavity.
- the scope here is to improve baking performance especially in terms of browning, crisping etc through the use of appropriate reflection.
- radiant heating elements in the form of quartz lamps two for each side of the oven cavity are used. These are housed in suitable metal reflectors that are attached to the external face of the cavity wall and covered either by a metal plate (which can be integral with the oven wall) or ceramic glass.
- the oven comprises a forced air fan and a heater for the main cavity and upper sub-cavity and two quartz lamps for the lower sub-cavity only.
- the heater can be a circular or non circular tubular heater or a quartz lamp.
- the walls of the oven cavity, of the oven door or accessories thereof are preferably coated with coatings including fluoropolymers with or without PTFE additives and fillers, Sol-Gel generated films and PECVD (Plasma Enhanced Chemical Vapour Deposition) generated films. All the above coatings have the specific intent to create an abrasive-corrosive resistant and non-stick surface applied to metallic (e.g. stainless steel) or non metallic (e.g. enamel) substrate. These coatings can be applied to all or part of the cavity or oven accessories or parts e.g. baking trays, oven door, racks etc. The coatings can be applied to sheet, pre-formed sheet or ready-to-use parts.
- coatings including fluoropolymers with or without PTFE additives and fillers, Sol-Gel generated films and PECVD (Plasma Enhanced Chemical Vapour Deposition) generated films. All the above coatings have the specific intent to create an abrasive-corrosive resistant and non-stick surface applied to metallic
- the separating and insulating plate may be made of a material different from metal, i.e. polymeric material (preferably silicone resin type), tempered glass and PyrexTM glass.
- the separating and insulating plate may also include a series of indications and/or guides (e.g. pressed/moulded directly in the plate material) to help the consumer position the food tray or container correctly. Further indications such as "Danger hot surface” or “Danger heavy weight” can also be added.
- the separating plate When installed, the separating plate sits on side supports that also act as heat and odour barriers around the perimeter of the cavity.
- the glass separating plate When tempered or PyrexTM type glass is used for the separating plate, visibility inside the cavity is greatly improved, although in this case thermal insulation is reduced. In order to improve thermal insulation, the glass separating plate may have an interspace in which vacuum is created. Visibility is further improved by using low voltage (24V) or high (220V) voltage, low (10-50W) wattage, halogen illumination devices in both sub-cavities. These can be positioned on any of the cavity walls although the preferred position is either at the rear of the cavity or on the side walls.
- High temperature silicone resin plastic may also be used to realise all or part of the separator; in this particular case the plastic is suitable up to 500°C continuous use i.e. also for pyrolitic ovens.
- an oven 10 comprises a cavity 12 having four heating elements 14, two for each side 12a of the oven cavity, which are housed in flat metal housings or "pockets" 16.
- Two flat housings 16 are located on the external face K of the cavity 12 at each side 12a of the cavity and connected electrically through the back plate of the oven.
- the flat housings 16 are vertically separated in order to provide a thermal insulation between them.
- a shelf-shaped separating plate 18 can be inserted (figures 4-8) that splits the cavity 12 in two sub-cavities 12b and 12c.
- the separating plate 18 has thermal insulating properties and is provided with a silicone seal (not shown) in the front portion thereof in order to seal the front wall of the cavity i.e. the oven door.
- each flat housing 16 contains a tubular heating element 13 which faces directly the external face K of the side wall of the oven cavity.
- Each heating element 13 has electrical connections 13a linked to the electrical circuit of the oven 10.
- each heating element is a twin radiant heating element 40 comprising a metal flat housing 42 containing two dickey bow shaped heating elements 44 each having electrical connections 44a on the rear wall of the oven.
- Each twin radiant element 40 is attached to the centre of the oven side wall, which can be provided with a longitudinal slot 46 in order to improve the heat transfer to the separating plate 18.
- a metallic or a ceramic glass plate 42a can close the face of the housing 42 towards the external face K of the side wall.
- the slot 46 is an opening having the same dimension of the ceramic glass plate.
- the oven comprises four radiant heating elements in the form of quartz lamps 50, two for each side of the oven cavity 12. These are housed in suitable metal reflectors 52 that are attached to the external face K of the cavity wall and covered either by a metal or ceramic glass 54.
- the oven 10 comprises a forced air fan 56 and circular heater 58 for the main cavity 12 and upper sub-cavity 12b and two quartz lamps 50 for the lower sub-cavity 12c only.
- a quartz lamp 59 can be used (shown in the same figure 8).
- the oven can be used as a standard oven (static and/or lower element) or together with the four side heating elements.
- performance e.g. cooking results
- standard radial heater configuration circular heater around fan
- the separating plate 18 is used to split the oven cavity thus providing three further modes of operation:
- the separating plate 18 is provided so as to isolate and insulate the two sub-cavities. This is done by carefully sizing the separator to match the cavity interior profile (incl. oven door) and using a silicone rubber seal fitted on the front of the separator. When in use it sits on a suitable ledge attached to the cavity wall.
- the temperature control and sensor of the lower sub-cavity is enabled e.g. through a micro-switch fitted at the rear of the oven cavity.
- the installed power for each side wall heater is preferably between 250W to 1500 Watts. Where the heater on the rear wall is used (figure 8), its power is preferably 500 Watts or higher.
