Definitions
- Gasket, oven part equipped with such a gasket and furnace comprising such a gasket
- the present invention relates to a seal and an oven part equipped with such a seal and an oven comprising such a seal.
- a seal sealing member mounted on the front face of the oven or on the door and interposed, in the closed position of the door, between its two elements.
- the seal is traditionally retained on the furnace element which receives it by means of clips located at different points along the length of the joint.
- the seal is for example a lip seal whose lip comprises a rigid piece.
- the invention proposes a gasket comprising an envelope defining in section a bulb suitable for deforming to seal and a lip extending from the bulb, characterized in that an element having an elasticity perpendicular to said section is received in the lip.
- Elasticity perpendicular to the section that is to say in general in the general direction of extension of the seal, allows to press the lip on the device that receives the seal and therefore ensure its mounting in contact with these measures.
- the seal extends for example in a closed curve, as is the case for seals intended to be mounted around the cavity of an oven to seal the closure by the oven door.
- the aforementioned element is for example a spring which extends in the general direction of the joint.
- the spring can then be under tension and also define a closed curve in its length, in which case the spring can grip the device on which the seal is mounted and thus ensure its attachment.
- the spring is for example in practice received in a secondary bulb located at the end of the lip.
- the envelope may be made of braided textile and the bulb may also receive a metal knit of generally cylindrical shape.
- the invention also provides a furnace part (for example a door) comprising such a seal, wherein the element encloses the furnace part in order to ensure its attachment thereon.
- a furnace part for example a door
- the element encloses the furnace part in order to ensure its attachment thereon.
- the invention thus furthermore provides an oven comprising a muffle and a front face defining between them a chute of generally rectangular shape, characterized in that a seal as described above is mounted in the chute.
- the chute is thus used for fixing the seal.
- the element having elasticity can thus grip the muffle.
- This element is for example elastically plated at the end of a return flange of the muffle.
- the chute defines a rounding between two chute portions defining said rectangular overall shape, which avoids the formation of angular points in contact with which should come the elastic element.
- FIG. 1 shows a perspective view of a portion of an oven to be equipped with the seal proposed by the invention
- FIG. 4 is a section of a seal made in accordance with the teachings of the invention.
- - Figure 5 shows the oven part of Figure 1 equipped with the seal of Figure 4;
- FIG. 6 is a section along the plane VI-VI of Figure 5;
- FIG. 7 represents the detail VII defined in FIG.
- FIGS. 1, 2 and 3 show the muffle 2 and the front face 4 of an oven.
- the muffle 2 is of parallelepipedal general shape and defines the cavity 8 intended to receive the food to be cooked.
- the muffle 2 is therefore designed in a manner adapted to the high temperatures it undergoes and is thus generally produced in the form of a separate part of the remainder of the oven (and in particular of the front face 4), which also limits the heat transfer of the muffle 2 to the other parts of the oven.
- chute there is therefore in general a gap 6, called “chute”, between the muffle 2 and the front face 4, which extends here around the entire muffle 2 and therefore has a generally rectangular shape.
- the transition between two sides of the rectangle defined by the chute 6 is done by means of roundings to avoid angular points.
- the muffle 2 further defines at its portion intended to be received at the front of the furnace a crown 3 extending the walls of the muffle 2 defining the cavity 8 and extending in a plane perpendicular to these walls (and therefore a once mounted, in the plane of the front panel 4).
- the front face 4 and the crown 3 each extend at the level of the trough 6 by a rim 5, 7 which extends towards the inside of the furnace, that is to say, parallel to the walls of the muffle 2 defining the cavity 8 and the side thereof relative to the front face 4.
- the chute 6 is defined between the flange 5 of the front face 4 and the rim 7 of the ring 3 of the muffle 2.
- a seal 10 to be mounted in the chute 6 which has just been described.
- the seal 10 comprises an envelope (or sheath), here made of braided textile, which defines in section (that is to say as visible in Figure 4) a bulb 12 (said main bulb) of generally circular shape. section, from which extends a lip 16 (sometimes referred to as “flange”) whose end 14 (which also defines a generally cylindrical space of diameter less than the bulb 12, and is therefore sometimes referred to as "secondary bulb”) receives a spring 20.
- an envelope or sheath
- braided textile which defines in section (that is to say as visible in Figure 4) a bulb 12 (said main bulb) of generally circular shape. section, from which extends a lip 16 (sometimes referred to as “flange”) whose end 14 (which also defines a generally cylindrical space of diameter less than the bulb 12, and is therefore sometimes referred to as "secondary bulb”) receives a spring 20.
- the cylindrical shape of the bulb 12 and its elasticity in the section plane of FIG. 4 intended to ensure the seal provided by the seal are permitted here by the use of a metal knit 18 of generally cylindrical shape and received at the Inside the envelope at the level of the bulb 12.
- the spring 20 is here a spiral metal spring and thus has an elasticity along its own length, that is to say perpendicular to the sectional plane of FIG. 4.
- the seal 10 is intended to be mounted in the chute 6 and has for this purpose a generally closed shape of length equal to the perimeter of the chute 6.
- the spring 20 has a rest length less than the perimeter of the chute 6 while it also extends continuously over the entire length of the seal 10 (for example by means of a splicing operation) of so that it is mounted in tension in the seal 10 (which however does not pose any difficulty thanks to the relative elasticity of the envelope formed of braided textile).
- the seal 10 is for example obtained by overbraiding the envelope on the metal knit 18, then by inserting the spring 20 (not yet closed on itself) in the lip 16, by splicing the spring 20 (for example by inserting the turns at one end in the turns at the other end) and so the joint itself to obtain the closed shape, then by stitching the two ends of the seal 10 (formation of a sticker).
- FIGS. 5 to 7 show the gasket 10 mounted in the duct 6 formed as already indicated between the front face 4 and the muffle 2 of the oven.
- the lip 16 of the seal 10 is inserted into the chute 6 and has a length slightly greater than the rim 7 of the crown 3 of the muffle 2 so that its end 14 is at the level of the end of this rim 7.
- the seal 10 is thus retained in the chute 6 and the bulb 12 of the seal 10 is then positioned on the front face 4 of the oven to ensure tightness when the oven door (not shown) comes into contact with the front face. 4.
- the proposed solution makes it possible to press the bulb 12 against the crown 3 and the front face 4 at the chute 6, and this over the entire periphery thereof , which avoids any air circulation at the chute and ensure good thermal insulation at this location. It will be readily understood that the proposed solution allows a particularly simple mounting of the gasket 10 on the oven.
- the use of the chute 6 for mounting also avoids providing dedicated locations for mounting the seal and thus improves the freedom of design of the oven.
- the assembly of the seal 10 in the chute 6 is for example manually, starting for example by introducing the sticker, then gradually the entire seal, the passage of the spring 20 in the chute 6 over the entire perimeter of the this being allowed in particular by the elasticity of the spring 20.
