Description

Electric toaster

  The present invention relates to an electric toaster

  It has two sides of the heating elements and is bordered on two small sides by reflective transverse walls. We know by the German utility model nO

  77 18 602 a toaster of this kind. We meet this

  that, for reasons of electrical isolation,

  Heating ducts are not brought exactly to the transverse walls and as a result the vertical edges of the bread slices are less strongly grilled. Furthermore,

  in the middle zone of the roasting chamber, each

  Bread is subjected to radiation action from a variety of angles from different locations of the heating element. On the edges, however, the rays come only in one direction, so that the intensity of the radiation acting on the product to be grilled is

also diminished.

  The invention relates to a toaster whose effect on the grilling product is standardized without increasing

  notable of its cost of realization.

  This toaster is characterized in that between the heating elements and a slice of the grilling product inserted into the grilling chamber, the transverse walls have reflective sections which form with the plane of the neighboring heating element an obtuse angle in said roasting chamber. At least in the zone immediately adjacent to each plane of the heating element, this obtuse angle can be approximately between 100 and 130, preferably between and 120, and in particular close to 110 degrees. This arrangement offers the advantage of ensuring, without enlargement or elongation of the roasting chamber, uniformity of the appearance of the

toasting in the edge area.

  Between the reflective wall sections, the transverse walls preferably have, projecting into the grating chamber, each a centering advance, or frontal stop, for the product to be grilled, which thus keeps the latter at a minimum distance from said reflective sections. . Finally, the reflective wall sections can be curved so that as one moves away from the plane of the neighboring heating element, the angle they form with it in the roasting chamber decreases. * Rays arriving from different angles are thus

  think even more favorably for the result of the grill-

lage.

  With a front stop for grilling

  narrowingly narrow, oblique reflective wall sections

  also allow to grill the front part of the product.

  The invention will be better understood with the aid of

  Detailed description of two embodiments taken as non-limiting examples and schematically illustrated by the accompanying drawing, in which: Figure 1 is a side elevational view of a toaster according to said invention; Figure 2 is a section along the line II-II of Figure 1; FIG. 3 is a sectional view similar to that of

  FIG. 2 of a toaster corresponding to a mode of realization

changed.

  The toaster shown in Figures 1 and 2 has a mesh chamber housing 2 which is associated with a control portion 4 provided with a lift lever 6 and a knob degree of grilling 8. The housing 2 has a cap-shaped cover 10 which surrounds a chamber of

  roasting 12 for two slices of bread 13 can be placed one

  the other on a support 14 and shown in

  Continuous in Figure 1. Vertical transverse walls

  18 and 20, which have vertically pressed grooves

  shims 22 to accommodate heating elements 24 are

attached to a bottom portion 16.

  The heating elements 24 have a frame of vertical bars of insulating material 26 which are interconnected at their upper and lower parts by unrepresented U-shaped profiles. A conductive heating tape 34 is wound on the chassis thus obtained in several turns

  horizontally, to fix their spacing, to

  to the marginal notches 36 of the bars of insulating material 26. The bars of insulating material 38 remaining between the indentations 36 penetrate into the grooves 22 of the

transverse walls.

  The marginal indentations 36 of the strips of insulating material 26 are a little deeper in the horizontal direction than the grooves 22 of the transverse walls, so that the heated conductive ribbons are brought to the vicinity of said transverse walls, but stop at a certain distance.

distance from them.

  Between the heating elements 24 and the slice of bread

  13, reflective sections 30 and 32 of the transverse walls

  With the planes of the heating elements 24, 18 and 20 form an obtuse angle of 1100 in the roasting chamber. Between these reflective sections 30 and 32, another section 34

  used as a stop for the grilling product

  the abutment surface is far enough so that its abutment surface is in the same plane as the outer marginal areas of the transverse wall 18. As an alternative to this embodiment, the abutment wall section 34 may also be

  more protruding into the roasting chamber in order to

  bring the product to be grilled a little further into the better irradiated area. Nonetheless, the special arrangement of the reflective wall sections 30 alone provides an essential improvement in the roasting result in the zone of the edges of the product to be grilled without extending the roasting chamber. center the product at a greater distance from the front end of said chamber. A few spoke objects shown in FIG. 2 make it possible to better discern the effect of reflective wall sections.

and 32.

  FIG. 3 represents a modified embodiment on which a transverse wall 318 is recognized,

  a heating element 324, a slice of bread 313 and a

  reflective wall 330 which, in its outer portion adjacent to the heating element 324, is flat and forms an angle

  obtuse about 1100 with the plane of the heating element 324.

  Further away from said heating elements, and closer to the

  bread slice 313, the zone 336 of the reflective wall section

  The curvature 330 is curved about one or more vertical axes toward the interior of the grating chamber such that as one moves away from the heating element 324, the angle formed with the plan of it goes decreasing

  until reaching a value of about 900 at approximately

  of the roasting plan of the product 313.
