Definitions

  • the invention relates to cooktops and gas stoves or electric, in which the supply of gas or electricity to the fires (gas burners or electric hotplates) is regulated electronic. More particularly, it concerns the integration of this electronic control in a small space near the traffic lights.
  • the maximum temperature that can be tolerated by electronic components is of the order of 70 ° C, while the temperature at The vicinity of the fires is of the order of 140 ° C.
  • This problem affects particularly the power card because it must be located near fires on which it operates, the heat of which is added to the heat dissipated breast (Joule effect), especially for cooking appliances electric. Therefore, in conventional devices, the card power electronics is placed at the back of the cooking appliance because the temperature is lower than at the front; in addition, this card is cooled by a fan. As a result, known devices of this type have relatively large dimensions.
  • Such an apparatus is known for example on the basis of the JP-11 patent application. 211098, which discloses a device for cooling a cooker control unit by means of a stream of air passing through said control unit and generated by a fan located in the stove near its rear end.
  • this document teaches to expel the draft from the stove on the one hand through a perforated surface mounted on the rear face of the stove, and on the other part through a gap between said perforated surface and said rear face.
  • the object of the present invention is therefore to propose a device thermal insulation and cooling of small dimensions, but enough effective to allow placing a power electronics near the burners or hobs without the electronics being damaged by the heat they give off.
  • the power electronics is placed in a housing forming channel, in use, for a cooling air stream of this electronics, said housing having one or more inlet ports and one or a plurality of outlets for said air stream, and further containing a blower intended to produce this flow of air, the electronics being located along said channel between said air inlet ports and said fan.
  • the housing may conveniently consist of two arms joined one to the other, one of these arms having said air intake ports near its end free, and the other arm having said air outlets near its end free.
  • the outlets will be fitted on the underside of the housing, and choose a fan of the type "axial fan" that will be placed above air outlets.
  • the figures show a housing according to the invention intended to regulate the admission of gas to the burners, and possibly also the admission of current electric hobs, a hob (not shown).
  • This housing has the general shape of two straight arms 1 and 2 joining preferably at right angles.
  • a "power" electronics 3 for example a card containing the logical components necessary for the control of the supply of gas and electricity, is placed in the housing, preferably in the corner formed by this junction between the arms 1 and 2.
  • the entire housing rests on the frame of the camera cooking, to which it is connected by simple fixings, a layer constituted a thermally insulating material being interposed between the housing and this frame.
  • control box in general, the control box according to the invention being of modular design, it can be placed at choice at the front or on the side of the electric burners or hotplates, depending on the shape of the cooking appliance used and its position by compared to kitchen walls, or other furniture such as an oven.
  • the lamps are located within the angle formed by arms 1 and 2, that is to say near the respective internal faces 6 and 7, the latter will be covered with an insulating layer.
  • the face 9 of the arm 2 look to the front of the cooking appliance (that is to the user), and the face 8 of the arm 1 looks backwards.
  • the use of thermally insulating layers is insufficient to maintain the temperature electronic components, in use, at a tolerable value.
  • the invention therefore provides for cooling the electronic card 3 by means of a air flow produced by a fan 5, which will preferably be actuated by the electronic card 3 itself.
  • the housing in its set has been designed to optimize the flow of air (represented by arrows) on the electronic chart 3, taking into account the limitations space and therefore especially the necessarily limited size of the fan 5.
  • the air intakes 11 are located on the arm 1, at the level of the rear face 8 and outer side face 10; thus, the incoming air is taken in the environment of the cooking appliance where this air is most cold ("crawl space" at the back and on the side of the cooking appliance).
  • the air flow is carefully channeled along the housing of ordered ; specifically, the airflow first goes to the front of the housing along the arm 1, then it branches to the arm 2 passing on the map electronics 3 so as to cool it energetically; the fan 5 is arranged near the free end of the arm 2, so that the air flow passes through then the fan 5 before being ejected from the housing through a grid 12.
  • the fan 5 can be automatically, even when the lights are not used, in case the temperature in the housing would rise dangerously, for example because of the use of an oven placed under the hob.
  • the fan 5 can be triggered by the signal emitted by a conventional temperature probe connected to the electronic card 3.
  • the walls of the housing can be made of sheet metal, material plastic, or any other suitable material.
