FR2617951A1 - THERMAL PROTECTION DEVICE FOR COOKING OR HEATING APPARATUS - Google Patents

Abstract

The invention relates to a removable adaptable thermal protection device on the external face of the door of cooking or heating appliances. This device is constituted by a removable grill (1), made of a number of elements (1a, 1b) which can be separated or folded against one another, which is fixed against the door (8) of the appliance by means of cupels made of magnetic metal (7) and of magnets (4), of suction cups or of glued distance pieces.

Description

The invention relates to a removable thermal protection device,

  adaptable on the outer surface (eg door) of cooking or heating appliances, designed to protect children and pets from burns by accidental contact. Currently, the regulations in force

  in the different countries of the EEC require

  that the external temperature of the doors of these appliances does not exceed in operation, a certain temperature defined according to the energies

  used by the apparatus and materials constituting

killing the front of these.

  However, at these temperatures, prolonged accidental contacts can cause burns

  especially young children

  leading to walk. In addition, cooking appliances are often equipped with a self-cleaning device by pyrolysis of fat residues projected during cooking against the internal walls of the appliance, including the inner face of the access door; which further increases the risk of burns since, in this case, the internal temperature of the

oven reaches 5000C.

  It is known to fix, on the outer face of the doors of a cooking appliance, a removable protective grille arranged parallel to the doors leaving a certain space with respect thereto. However, in case of prolonged use

  of the oven, this protective grid ends up

  iron and by present risks of burns she

  as well. In addition, these grids made of metal rods

  interlinked, are generally made in one piece and therefore have difficulties of cleaning and storage, taking into account

their size.

  We already know devices such as

  the one described in the German utility model DE-

  DE-A-7 224 332, which consists in covering the outer face of the window of an oven door with a transparent plastic film intended to reduce the contact temperature. However, the temperature reduction obtained by this means is not sufficient to eliminate any risk of burns during prolonged contact, as is the case when a very young child comes

  to take support by his hands against the door of an oven.

  There is also known a device such as that described in the French utility certificate FR-A-2 310 073 which consists of applying on the outer face of the door cooking appliances, thin

  strips of plastic material arranged in horizontal line

  tale, these bands being sufficiently close together to

  direct contact with the door, can not occur

  re. These plastic strips can be rigid

  to form a grid intended to be fixed in front of the door of the apparatus with or without deviation from it, the fixing being carried out by

  bonding. Thus, the removability of this device protects

  is very limited, given its bonding. Its maintenance, as well as its storage have

not foreseen.

  The present invention aims to remedy

  to the disadvantages presented by the devices mentioned above. This invention, as it is characterized, solves the problem of creating a thermal protection device adaptable to any door of cooking appliances, equipped with a

  door with glass or teak facade whose temperature

  surface area reached, in use,

  likely to cause serious burns, particularly

  to young children. This device can

  be easily dismantled, cleaned, stored and reassembled.

  The device according to the invention is characterized

  mainly consists in that it consists of a removable grid, fixable in front of the door of a cooking or heating appliance, leaving a space with respect thereto, said grid being made in one or more elements foldable against each other and being fixable against said

  door by means of magnetic metal cups

  and magnets, suction cups or isolating spacers

your pasted.

  In the magnet attachment mode, the cups are fixed against the door by gluing and the magnets are fixed perpendicular to the grid, via a threaded end, a

  spacer washer and a screw made of insulating material.

  The cups have cavities of corresponding cross-section

  lying to that of the magnets, arranged in their middle.

  In the method of fixing by insulating spacers they are glued against the front face

  of the door and fixed to the grid by insulating screws.

  Spacer ribs, ensuring the rigidity of the grid after mounting, are located at the line of articulation and separation

  constituent elements of the grid.

  The advantages obtained thanks to this invention

  mainly consist in the fact that the grid adapts very easily to any appliance door

  and it can be very easily demon-

cleaned and stored.

  Other features and benefits

  will appear in the following description of a

  device according to the invention, given as an example

  non-limiting in the light of the accompanying drawings, on

  which: - Figure 1 shows a perspective view of a furnace door equipped with cups and a two-part protective grid provided with magnets and

a spacer rib.

  - Figure 2 shows a partial sectional view of the cup-magnet assembly, fixing the grid

on the door.

  - Figure 3 shows a partial sectional view of the suction fixture. - Figure 4 shows a partial view. chopped off

  of the fixing device by gluing.

  The figures show a thermal protection device for a cooking door, consisting of a removable grill 1, made of two elements 1a and 1b, joined by a removable hinge or not 2, provided with a spacer rib 3 and magnets 4 fixed by means of a threaded end 4a, a spacer washer 5 and an insulating nut 6, and cups 7, glued against the front face of the door 8 equipped with the porthole 9 by means of suction cups 10 or via spacers

  11 glued directly to the front of the door.

  According to the present invention,

  the protective grid 1 consists of two elements

  1a and lb joined by a removable hinge or not 2 so as to allow the folding of the two elements la and lb, against each other or to obtain the separation

  of these. The spacer rib 3, ensuring the rigidity

  dity of the grid when it is secured to the door, is attached to one of the elements la or lb of the grid, near the removable hinge

2, parallel to this one.

  The magnets 4, fixed in the corners of the grid via the threaded end 4a, the spacer washer 5 and the insulating nut 6, are housed in cavities 7a arranged

  in the axis of the magnetic metal cups 7 before

  stuck, using a template against the face

outer door 8.

  In the sucker attachment mode 10, these are fixed in the corners of the grid

  and come to fit against the front of the door.

  In the method of fixing by insulating spacers it glued directly against the front face of the door, they are fixed in the corners of the grid by means of screws 12 of insulating material. Thus, this protective grid can be easily adapted to all kinds of doors

  cooking or heating appliances by users

  themselves, using a template supplied with the grid, since it is sufficient to stick the cups 7 or the insulating spacers 11 against the front face of the door, according to a predetermined arrangement,

  or by operating on the fan control device

its 10.

  This grid can thus be

  due to its design, easily assembled or dismantled

  as required; since it can be stored in

  pant a minimum of space. Cleaning the front of the door and the back of the grille

is thus greatly facilitated.

  The thermal protection device

  according to the invention, is intended primarily for equipping

  front door ovens for electric or gas ranges, as well as heating appliances, such as

as poêles and inserts for example.
