Definitions
- the present invention relates to a cold door oven.
- the invention relates more particularly to ovens for use domesticated. It can of course also be applied to ovens intended cooking food used in communities. In such ovens, the temperature is around 200 to 250 ° C throughout the cooking time of a food, that is to say sometimes for several hours.
- Such an oven has a door that allows access to the interior of it to place and remove food. During cooking, the oven door heats up and sometimes reaches temperatures that can cause burns. This door is usually the accessible part of the oven, the other partitions of the oven being most often embedded. To avoid causing burns, avoid heat loss heat from the oven door.
- the document FR. 2,557,272 relates to a door to a cooking appliance having a frame metallic enclosing two parallel panes spaced from each other.
- the document FR 2 639 097 relates to a double door oven.
- This door consists of a rigid supporting frame, by means of rods guide, an inner plate biased by springs. The closure is provided by the inner plate which slides relative to the frame and supports a peripheral seal.
- the various known devices make it possible to have temperatures at the oven door which is around 55 to 60 ° C after one hour of cooking. Most of these ovens are fitted with glass doors because it burns less easily on contact with this material than on contact with a metal plate which is at the same temperature.
- the object of the present invention is therefore to provide an oven having excellent thermal insulation at the door so as to obtain a “colder” door than the oven doors of the prior art.
- the cold door oven it offers is an oven having an enclosure having a closable opening by a hinged door.
- the enclosure is mounted on a chassis with insulation the enclosure with respect to the chassis, and the oven door is hinged on the frame.
- the enclosure is an enclosure isolated with feet, preferably four in number, and these feet are placed on the frame with interposition of insulation between the feet and the frame. Air is then used as insulation between the retort and the frame. The feet are necessary to put the retort on the frame but we try minimize contact between the retort and the chassis.
- the door is a pivotally mounted door around an axis on the chassis. This door opening movement is found on most ovens.
- a seal is advantageously mounted on the periphery of the opening of the enclosure and provides a seal between the peripheral edge of this opening and the closed door of the oven.
- the invention also provides a structure for the oven door.
- This includes a frame mounted to pivot on an axis, a facade exterior, interior door lining, as well as insulating means arranged between the exterior facade and the interior lining so that no direct contact is made between the exterior facade and the lining interior. In this way a thermal break is made between the lining internal of the door and the external frontage of this one.
- the oven door is by example of a generally rectangular shape, the axis of the door is located substantially at one side of the door. The thermal separation between the front facade and the inner lining can then be produced by a layer insulating material on the axis side of the door and by a seal on the three other sides of the door.
- the oven according to the invention may also include a handle of door on the side of the exterior facade and this handle is preferably attached to the door frame.
- a deflector can be provided on the front panel between the door and the hob.
- this oven allows energy savings during cooking food.
- Figure 1 is a longitudinal section through an oven along the invention.
- This oven has an enclosure, or retort placed on a frame 4 on which a door 6 is pivotally mounted.
- Retort 2 is a relatively retort oven retort classic. It is for example intended to be heated by a burner with gas or by electric resistances. It has a shape substantially parallelepiped and one face of this parallelepiped has a substantially rectangular opening 8. This retort presents also four feet 10 (of which only two are visible in Figure 1) on which the retort 2 rests.
- the chassis 4 is a metallic structure which carries the retort 2, a covering 12 as well as an insulating structure 14 placed all around the retort 2, except at its face having the opening 8.
- the frame has on either side of this opening, in the lower position, that is to say of the side of the feet 10, a bearing 16 intended for the pivoting mounting of the door 6.
- the opening 8 has a substantially peripheral peripheral edge rectangular.
- a seal 18 is mounted all along this peripheral edge. he seals between the opening 8 and the door 6.
- a protection 20 is fixed to the covering 12 on the side opposite the bearings 16. This protection 20 prevents the control buttons located above the door from the oven are overheated. These can be control buttons for the oven but also for a hob associated with this oven.
- pads 22 made of an insulating material. These skates avoid conduction of the heat produced in the retort 2 towards the frame 4.
- FIG. 2 shows in detail the structure of door 6. This the latter in particular comprises a frame 24, an inner lining 26 and an exterior facade 28.
- the inner lining 26 and the outer facade 28 are sheet metal plates whose four edges have been folded. As we can see in Figure 1, the dimensions of the inner lining 26 are such that it can come to fit into the outer facade 28 with a game.
- the frame 24 is formed from four metal tubes: two vertical tubes 30 connected by two horizontal tubes 32.
- the end lower of the vertical tubes carries an axis 34.
- the latter is intended for cooperate with the bearings 16 of the chassis 4 to allow mounting pivoting of the door between a closed position where the lining 26 comes press against the seal 18 and thus close the opening 8 and an open position rotated approximately 90 ° from the position closed.
- the door is then assembled in the following manner.
- the inner lining 26 is placed on the frame 24.
- a flange 36 is provided on the inner lining 26 to allow the maintenance thereof on the frame.
- a plate 38 of insulating material is disposed between the frame 24 and the inner lining 26.
- the space left free between the tubes vertical 30, horizontal tubes 32 and edges of the inner lining 26 are filled with pieces 40 of insulating material.
- On the axis side 34 the edge of the internal lining 26 is protected by parts 42 of insulating material.
- a seal 44 is placed.
- all around the inner lining 26, is a thermal barrier made in a insulating material.
- a second insulating plate 38 then covers the frame 24 and the front face 28 of the door is placed on this assembly mounted, like a cover. Fixing screws not shown come maintain this "cover" on this assembly.
- a handle 46 is also provided on the door 6. This handle is fixed on the frame 24. The latter is provided with threaded rods 48 which, in the mounted position, pass through an insulating plate 38 and the facade outside 28. The handle 46 is then mounted on these two threaded rods 48.
- This door 6, thus mounted, is mounted in a conventional manner on the two bearings 16 of the chassis 4.
- the exterior facade 28 is very good isolated from retort 2. Indeed, there is no direct contact between the inner lining 26 and the outer facade 28. A thermal break is made between this lining 26 and the facade 28.
- the handle 46 of the oven heats very little during the oven operation. Indeed, it is mounted on the frame 24 of the door 6 which is itself well insulated from the retort.
- this frame is not mounted directly on the retort but on the chassis which is insulated retort.
- the door it remains “cold” even during operation. It is possible not to exceed 45 ° C for the door temperature. If a plate of cooking is associated with this oven, the front face of it can remain also cold. The assembly formed by the oven and the hob then presents a front panel which remains entirely cold, without risk of burns from contact with one hand.
- the insulation between the retort and the frame is made in that the retort is equipped with feet and that these rest by insulating pads on the chassis. Another insulation between the retort and the chassis could be performed.
