Definitions

  • the present invention in a first aspect thereof relates to a cooking device comprising one or more gas burners that extend through a passage in a work surface and each have an associated pan support such that each gas burner extends through a separate corresponding passage.
  • Such cooking devices are known.
  • said work surface When the work surface directly surrounds a burner and since a pan support bears directly on the work surface, i.e. not via a catchment dish of a gas cooking range, said work surface will be heated by radiation heat of the flame of the gas burner, by conduction heat of the pan support resting on the work surface, and radiation heat of a pan heated by the gas burner, resting on the pan support, and accordingly located somewhat above the work surface during operation of the gas burner.
  • Such heating is undesirable because it may pose a burning risk to a user who comes into contact with the work surface, because a heated work surface is detrimental for any food lying or being prepared on the work surface, or because the work surface is affected by the heat, whereby the risk of fracture increases.
  • the present invention accordingly has for its object to provide a device as described in the opening paragraph wherein the temperature of the work surface rises less high than in a comparable combination of work surface and gas burner according to the know solution.
  • This object is achieved according to the present invention in that for a particular pan support at least one thermally insulating element belonging to the particular pan support in question is provided which during operation of the cooking device has a reducing effect on the heat transfer from the pan support in question and/or a flame from the corresponding gas burner to the work surface.
  • a work surface as used herein, means a surface on which food can be prepared by a user.
  • the scope of protection preferably further extends to a cooking range (to be) integrated in the work surface, at approximately the same level as the work surface and in which the gas burners are incorporated.
  • the term 'particular' indicates that a thermally isolating element is provided for a particular pan support, impeding heat transfer between the said pan support and the cooking range. It will be obvious that the cooking range does not belong to a particular pan support, but to the joint pan supports.
  • the mounting member with the at least one thermally insulating element ensures that the heat transfer from the flame of the burner, from the pan support and/or from the heated pan on the pan support to the work surface is hampered.
  • the thermal insulation may be constructed in various ways, some of which will be discussed herein.
  • Japanese patent document JP 10-170003 discloses a cooking range of a stove that is integrated in an opening of a slab.
  • the gas burner and the pan support are connected to the work surface via the mounting member that comprises the at least one thermally insulating element.
  • the thermally insulating element may thus be included in or form an integral part of connecting means by which a gas burner is usually fastened to the work surface. It at least reduces the heat between the gas burner and/or the pan support and the work surface.
  • a radiation heat insulating element is provided that is designed for preventing, or at least substantially reducing, the transfer of heat through radiation from a pan bottom, from the pan support, or from a flame of the gas burner to the work surface.
  • the work surface in a device according to the prior art is heated inter alia by radiation heat from the elements mentioned above.
  • the heat radiation insulating element accordingly reduces at least in part a rise in temperature of the work surface as compared with the prior art.
  • the heat radiation insulating element comprises two shells lying one on top of the other and located between the pan support and the work surface.
  • Said shells are preferably made from a thermally conductive material so that any heat can spread evenly over the shell.
  • the pan support may or may not be fastened to the uppermost one of the two shells.
  • a contact heat insulating material may be used for this so as to reduce the transfer of heat through contact from the pan support to the radiation heat insulating element.
  • Two shells on top of one another may be separated by a thermally insulating material, but a sufficient radiation heat insulating effect is achieved, for example, when the material present between the two shells is at least substantially formed by air.
  • spacer elements of an insulating material are present between the shells.
  • the radiation heat insulating element may at the same time act as the mounting member.
  • the shells have a surface area that corresponds substantially to that of a pan bottom to be supported by the pan support. If the shells extend at least as far away from the burner as the maximum diameter of a pan to be placed on the pan support, the radiation heat of a pan bottom in the direction of the work surface is reduced in the desired manner.
  • a contact heat insulating element is provided, designed to reduce at least to a high degree a heat transfer through contact between the mounting member and the work surface.
  • the contact heat insulating element may in this case be provided between the mounting member and the work surface, but it may alternatively be provided in the mounting member, for example as an interruption thereof, such that the portion of the mounting member facing the work surface can indeed rest directly on the work surface, but since this portion is insulated from the higher portion of the mounting member, the heat transfer is still reduced.
  • the contact heat insulating element and the radiation heat insulating element may be combined into one element.
  • the contact heat insulating element preferably comprises at least one support element by means of which the mounting member bears on the work surface. If a plurality of support members is provided, these may together form a continuous support member which at the same time, for example, provides a good seal against, for example, moisture. It is alternatively possible, however, that several support members are located at a distance to one another.
  • the contact heat insulating element is preferably a ring of insulating material that is provided on or in the work surface and on which the mounting member is supported.
  • the contact heat insulating element is preferably manufactured from silicone material, but obviously alternative materials may be used which are resistant to the temperatures to which they are exposed during use in a kitchen environment and which in addition have a thermally insulating effect.
  • the work surface comprises two or more passages for gas burners, said gas burners being connected to one another below the work surface.
  • the present invention in a second aspect thereof relates to a gas burner with a pan support and a mounting member which comprises, at least when used in a work surface, at least two shells lying one above the other and which is located, at least when used in a work surface, between the gas burner plus the pan support at one side and the work surface at the other side. Further developments in such a gas burner with a pan support and a mounting member are discussed in the present document, for example with reference to the first aspect of the present invention.
  • the present invention further relates to a gas burner with a pan support and a mounting member, wherein the mounting member is provided with at least one contact heat insulating and/or radiation heat insulating member which is designed for preventing or at least reducing the transfer of heat from the mounting member to the work surface.
  • FIG 1 is a perspective view of a cooking device 1 according to the present invention.
  • the cooking device has a work surface 2 of composite material in which holes (not visible in figure 1 ) are provided through which gas burners 3a to 3e and control knobs 4a to 4e extend.
  • a metal frame 5 for a gas burner assembly (not shown in figure 1 ) on which the gas burners 3a to 3e are mounted.
  • Figure 2 is an exploded view of partly assembled components of the cooking device 1 of figure 1 .
  • the work surface in figure 2 has dimensions corresponding to a gas burner assembly. It will be clear, however, that the work surface will usually be larger and in fact broader than shown in figure 2 .
  • the gas burners 3a to 3e and the control knobs 4a to 4e for the gas burners 3a to 3e are mounted on the gas burner assembly 11.
  • the gas burners 3a to 3e and the control knobs 4a to 4e are connected to gas lines 12 by means of the gas burner assembly 11 in a known manner.
  • Mounting members 13 and pan supports 14, which will be discussed in more detail with reference to figure 3 are arranged around the gas burners 3a to 3e.
  • the gas burner assembly 11 will normally be supplied factory-mounted, tested and certified. The mutual positions of the gas burners 3a to 3e and the control knobs 4a to 4e are thus fixed.
  • a frame 5 surrounds the gas burner assembly 11 when the cooking device 1 is in the assembled state.
  • An aluminium cooling plate 8 and the frame 5 are clamped against the work surface 2 upon installation.
  • the mounting members 13 and the pan supports 14 are removed from the respective gas burners 3a to 3e, so that the gas burners 3a to 3e can be passed through the holes 9a to 9e in the cooling plate 8.
  • the control knobs 4a to 4e are also removed so that the associated gas controls can be passed through holes 10a to 10e in the cooling plate 8.
  • the assembly thus obtained can then be mounted to the lower side of the work surface 2 in that the gas burners 3a to 3e and the gas controls are passed through the holes 6a to 6e and 7a to 7e in the work surface, respectively. Then the mounting members 13, the pan supports 14, and the control knobs 4a to 4e are reinstated and the cooking device 1 is ready.
  • Figure 3 is a cross-sectional view taken on the line I-I in figure 1 .
  • a round through hole 3a, through which a gas line 12a of the gas burner 3b extends, is present in both the gas burner assembly 11 and the cooling plate 8.
  • the gas line 12a is connected to a burner housing 15 on which a burner cover 16 rests.
  • a lower annular stainless steel shell 18 of the mounting member 13 rests on a flange 17 of the burner housing 15.
  • a silicone ring 19 is fastened to the lower side of the circumference of the shell 18, with which ring the shell 18 bears on the work surface 2 and which ring at the same time acts as a sealing ring between the work surface 2 and the mounting member 13.
  • the shell 18 is thus kept at a certain distance above the work surface 2 by the silicone ring 19.
  • the mounting member 13 thus comprises two shells 18 and 21 which are placed loose one upon the other and are kept at a distance to one another by studs 20. Accordingly the main substance present between the shells 18 and 21 is air.
  • the heat insulation effect of the cooking device 1 will now be discussed.
  • the object of this heat insulation is to reduce the temperature of the work surface 2 when the cooking device 1 is used for cooking.
  • a gas burner operates at full power, for example, on a known cooking device with gas burners directly mounted in the work surface, and a pan with boiling liquid stands on the pan support, the temperature of the work surface may rise owing to a number of effects:
  • the increase in temperature of the work surface 2 is reduced by the shells 18 and 21.
  • the upper shell 21 absorbs radiation heat from the gas burner 3b and the pan as well as heat from the pan support 14, or at least screens off the work surface 2 locally against radiation heat. Since the upper shell 21 and the lower shell 18 are separated from one another by air and by the rubber studs 20, there will be no or hardly any direct heat transfer from the upper shell 21 to the lower shell 18. However, there will still be some heat transfer through radiation from the upper shell 21 to the lower shell 18.
  • the lower shell 18 in its turn is kept at a distance from the work surface 2 by the silicone ring 19. Thus there is no or hardly any direct heat transfer from the lower shell 18 to the work surface 2.
  • the device according to the invention is capable of substantially reducing the temperature in the work surface 2, at least to a degree sufficient for providing an acceptable solution to the problem posed in the introduction.
  • the cooling plate 8 is provided under the work surface as an extra measure.
  • the cooling plate 8 is made from aluminium.
  • a local rise in temperature of the work surface 2 above the cooling plate 8 will result in a local transfer of heat from the work surface 2 to the cooling plate 8. Since the conduction coefficient of the cooling plate 8 is substantially higher than that of the work surface 2, the heat will distribute itself comparatively quickly over the cooling plate 8. At a distance from the relevant hot location the cooling plate 8 will in its turn give off heat to a relatively cool portion of the work surface 2 above the cooling plate 8.
  • the cooling plate 8 thus provides a faster distribution of heat over the work surface 2, so that local temperature rises remain limited.
  • the insulating elements may also be of an alternative design.
  • Other suitable radiation heat insulating materials may be used instead of silicones and rubber.
  • a suitable material other than stainless steel or aluminium may be used for the shells or the cooling plate.
  • For the cooling plate it is important that a material with good heat conduction should be used; for the shells this is not a requirement, but it is preferred because then the relevant elements will be evenly heated.
  • An insulating material may be provided between the pan support and the upper shell, if so desired.
