FR2628188A3 - COOKING PLATE EQUIPPED WITH A FEED SAFETY DEVICE - Google Patents

Abstract

The invention relates to cooking appliances. To prevent the cover 8 from being folded over the hob while the burners or hotplates 6 are in action, this cover has openings 9 which cannot fit on the control and adjustment buttons 7 of the supply to the burners or plates only if the latter are in their supply stop position. Otherwise the cover cannot be folded down fully and this indicates that the knobs are not in the off position. Main application: home appliances.

  To prevent the cover 8 from being folded onto the plate

  cooking while the burners or hotplates 6.

  are in action, this cover has openings 9 which can not fit on the buttons 7 for controlling and regulating the supply of the burners or plates only if the latter are in their stop position of the food. Otherwise, the lid can not be folded down completely and this

  Main application: home appliances.

  The invention relates to a safety device for the safety plate of the invention, and to the present invention. cooking especially for a plate of

  cooking of the household type, comprising heating units

  gas fires and / or electrical energy, control knobs

  located on the horizontal peripheral edge of one side or the front of the hob, and

  articulated hinged lid, generally

  the rear side of the hob.

  similar, as well as if these appliances are incorporated in independent furniture kitchens that if they are used as built-in components, provide for the use of valves or safety switches which do not allow the supply of fuel or in electrical energy only when the upper lid of the apparatus is raised to the open position as described, for example, in British patents

Nos. 109,919 and 2,144,845.

  In addition, it is already known, by the patents

  No 2 181 533 and No 2 181 534, to provide

  devices that emit a warning signal.

  if the lid is folded down when one or more

  Sieurs heaters are in action.

  These security features are unfortunate-

  cumbersome to be advantageously used in this type of devices, which are

  reduced (equal to or less than 30 mm).

  As a result, the construction and assembly of the hob is undesirably complicated.

  3D by the presence of levers, taps or switches.

  On the contrary, it would be desirable, and this constitutes the main object of the invention, to achieve

  a hob equipped with a food safety device

  tion which does not contain additional constituents and which is not only an easy

  also a small enough space for simplicity

  proud and streamline the construction and assembly of

the entire hob.

  These and other objects are achieved according to the invention with a built-in hob, particularly of the household type and comprising gas and / or electric heating units, one or more control knobs and on a horizontal peripheral strip, on one side of said cooking plate, and a hinged closing lid, also along one side of the

  hob, to oscillate between a horizontal position

  zontal or closing and a vertical position or

  opening, characterized in that the buttons are

  formed with a shape capable of interfering with the bottom surface of the lid brought into the closed position

  if a button is in a certain angular position

  different from its position of stopping the supply of

  electrical supply or gas supply.

  Figures in the attached drawing, given only

  by way of example, make it clear how

  vention can be realized. In this drawing, Figure 1 is a perspective view of the cooking plate according to the invention;

  FIG. 2 is an enlarged side view in part of

  sectional section of an adjustment knob in a closed position of the power supply, and while the lid is folded down; Figure 3 is a side view similar to Figure 2 but with the button in the feed position, rotated 180 relative to Figure 2, but with the lid down; FIG. 4 is a partial view from above

  Figure 1 shows the cooktop with

gas in the example shown.

  Along the perimeter of a

  control and adjustment buttons 7 of the burners 6.

  On the back side of plate 5, is articulated

  hinged a closing cap 8, made for example of transparent glass or metal, which can oscillate

  between a horizontal or a closed position (

  re 2) and a vertical or opening position (Figure 1). It should be noted that the closure cover 8 also extends over the peripheral plate

  along which are arranged the buttons 7.

  In addition, the upper end of the buttons 7

  is at a level higher than that of the surface ex-

  cover 8 in the closed position

(Figure 2).

  Therefore, the lid 8 is provided with an opening

  through 9, formed respectively at the right of the buttons 7 and which allow the lid to take

  its correct closing position (Figure 2).

  According to the invention, it is proposed a feed safety constituted by the geometric interference that is established between the buttons 7 and the cover 8 if the latter is placed in the closed position then

  one or more buttons 7 are in the authorized position

  Indeed, in the example described, the buttons 7 have a conically shaped body (FIGS. 2, 3) provided with a radial fin 10 and which is force-fitted on

  the stem 11 of the corresponding gas inlet valve.

  The axis of rotation of each knob 7 (FIG. 4) is offset relative to the central axis of the corresponding circular opening 9 by a distance "x" (FIG. 4) sufficient to cause the geometric interference between the radial fin 10 and the cover 8 when the latter is folded in the closed position while one or more of the buttons 7 are in a position

  any different from the closed position (

  re 3). The lid 8 can not be entirely

  In addition, the user has the possibility to

  immediately mark the incorrect position of the cover

  key 8 and correct it by returning the buttons 7 to

  power off (Figures 1 and 2).

  Thus we reach the main goal of the in-

  intervention, consisting in achieving a security of

  which does not require additional components

  brant. In addition, this feed safety can be achieved easily and it does not complicate the construction or mounting of the hotplate by

  levers and taps or switches traditionally

  tional. It goes without saying that various modifications and variants may be made to the device that has just been described, in particular by substituting the equivalent technical means, without thereby leaving the

field of the invention.

  For example, the surface of the neck is

  Or, the upper end of the buttons 8

  and the corresponding openings 9 of the lid 8 can

  button 7 takes to control the power supply, it is

folded in the closed position.

  Another variant could be made of the fact that the body of the lid 8 is cleaned in

  niches or re-entrances conformed in such a way that they can not
