Definitions

  • the invention relates to the field of the cooking appliances comprising a top sheet, a lower wall and at least four side walls connecting the top sheet and the lower wall, thereby delimiting an inner space of the appliance, wherein the top sheet has an external surface with at least a cooking hob.
  • Patent EP 2192352 B1 describes a cooking field having a top sheet, in which at least a cooking hob, a lower supporting element comprising a lower wall and side walls, and at least a fastening element to fix the top sheet to the lower supporting element in a detachable manner are arranged.
  • the object of the invention consists in providing a cooking appliance of a simplified construction and having a more robust structure.
  • a cooking appliance comprising a top sheet, a lower wall and at least four side walls connecting the top sheet and the lower wall, thereby delimiting an inner space of the cooking appliance, wherein the top sheet has an external surface having at least a cooking hob, wherein the lower wall is divided into at least a fixing fin and a closing lid and the top sheet, the side walls and the fixing fin of the lower wall are made in one piece of metal sheet forming a housing set.
  • the housing set is preferably made of a sheet of austenitic or ferritic steel with a thickness ranging from 2 mm to 0.4 mm, preferably from 1.5 mm to 0.5 mm, more preferably from 1 mm to 0.6 mm and, in a particularly preferred manner, amounting to 0.7 mm.
  • the manufacture process of the housing set comprises a series of steps consisting in cutting, folding and deep-drawing the sheet. Austenitic steel is preferred since it withstands better the deep-drawing process.
  • At least an electrical or gas cooking hob is mounted in the top sheet projecting heat towards outside the appliance.
  • the appliance can have more than one cooking hob of a different nature mounted in the top sheet on its external surface.
  • the cooking hob can be fixed to a cooking hob opening made in the metal sheet the top sheet is composed of, or can be fixed in an orifice of an intermediate element of top surface that is connected to the top sheet such as a ceramic glass forming part of the top sheet.
  • the at least four side walls extend downwards from the perimeter of the top sheet.
  • every two main planes formed by the side walls are parallel, even though this is not necessary and they could extend forming an angle different from a right angle relative to the main plane formed by the top sheet.
  • the metal sheet extends forming a fixing fin from the perimeter of at least two opposed side walls, opposed to the perimeter with which each side wall is joined to the top sheet, thereby forming the housing set of metal sheet in one piece.
  • a fixing fin part extends from each side wall and the closing lid is connected to these fixing fins forming the lower wall of the cooking appliance and forming a component box enclosing at least in part an inner space of the cooking appliance, in which the rest of appliance components are installed.
  • This configuration of the cooking appliance results in a more rigid structure better withstanding the stress due to the assembly of the rest of components and the stress due to temperature gradients generated by the heat from cooking in the cooking hobs. In this manner, deformations of the external surface of the top sheet visible to the user are avoided.
  • the closing lid is joined to the fixing fin by means of demountable fixing elements, thereby closing the inner space of the cooking appliance.
  • the perimeter of the top sheet outwards of the cooking appliance is folded on itself forming an appliance edge that can rest on a rim of an installation opening of a kitchen worktop. So, the side walls project downwards from the perimeter of the top sheet, remaining set back with respect to the outermost perimeter of the appliance edge, and the appliance edge forms a cantilever protruding from the rim of the installation opening when the appliance is mounted in the kitchen worktop. This simplifies the construction since the own housing set includes the appliance edge so the cooking appliance rests in the installation opening. When the cooking appliance is installed in the installation opening of the cooking worktop, the appliance edge rests on the rim and the component box is introduced in the installation opening.
  • the top sheet has a perimetral shaping sinking into the cooking appliance up to a base surface of the top sheet.
  • the shaping can be continuous around the whole perimeter of the top sheet or in parts, and it can be composed of undulations defining channels or figures on the surface of the top sheet.
  • the top sheet In order to place an area having the control elements of the appliance, it is provided that, on at least one of the sides of the perimeter of the top sheet, in the space between the perimeter and the base surface, the top sheet has a control surface raised with respect to the base surface, on which the control elements of the cooking appliance can be arranged.
  • At least a cooking hob shaping is provided on the top sheet extending around the cooking hob.
  • this shaping can extend around the entire cooking hob or a part of it and preferably protrudes towards outside the appliance, thereby raising the cooking hob with respect to the base surface of the top sheet.
  • the side walls extend away from the top sheet and are joined to at least one of the adjacent side walls with a connector at an edge of component box.
  • the connector can be formed by a flange protruding from one of the side walls and is fixed to the adjacent wall being screwed, welded, glued o clipped. Therefore, the connector can be fixed by welding o gluing or demountable such as clips or a screw.
  • a fixing fin part extends over the lower perimeter of the side walls towards the opposite side wall that, together with at least another fixing fin part, forms the fixing fin and this forms a surface to which the closing lid connects.
  • a fixing fin part extends from each side wall, giving more rigidity to the appliance when connecting with the closing lid. Furthermore, it is provided that, to strengthen the housing set, the fixing fin part of a side wall is joined at its end to the fixing fin part of the adjacent side wall, thereby forming the fixing fin.
  • This connection between fixing fin parts can be equally realized by means of any mentioned fixing system.
  • the fixing fin parts are arranged on a same plane and that the lid is so made with its perimeter on a same plane.
