DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to electrical cooking apparatuses, such as for example deep fryer, comprising a casing produced from a plastic material capable of degrading at a high temperature and which surrounds, leaving a certain space, a metal pan heated by a heating means, the said pan resting on a series of supports made from a heat-resistant material which are interposed between the upper edge of the casing and the upper edge of the pan, and which thus leave between them spaces between the said upper edges of the pan and of the casing in such a manner as to allow the circulation of air around the pan between openings made in the lower portion of the casing and the said spaces.
In known apparatuses of this type, where air circulation is maintained between the pan and the casing, it is necessary, during manufacture, to perform operations for indexing and for mounting the supports on the casing, centering the pan with respect to the supports, then fitting in and generally fixing the latter in the casing. These various operations are not suited to automated manufacture in full-scale production.
SUMMARY OF THE INVENTION
The object of the invention is especially to simplify the construction of such a cooking apparatus.
According to the invention, the said supports each comprise a head which is securely mounted on the upper edge of the pan and a body intended to come into engagement with the upper edge of the casing and comprising a fixing member with the said edge of the casing.
Thus, since the supports, are fixed directly onto the edge of the pan, it is possible to simplify the subsequent operations of fitting and fixing the pan in the casing, which makes it possible to have entirely automated manufacture in full-scale production.
Other advantageous characteristics are defined in the appended claims.
BRIEF DESCRIPTION OF THE DRAWINGS
The characteristics and advantages of the invention will emerge, moreover, from the description which follows by way of an example with reference to the appended drawings in which:
FIG. 1 represents, in perspective, a cooking apparatus, such as a deep fryer, before assembling the pan in the casing according to a first embodiment, and to which the invention is applied;
FIG. 2 is a partial vertical transverse section, on a large scale, illustrating a portion of the assembly of the pan in the casing by means of a support in accordance with a first embodiment;
FIG. 3 represents, in perspective, the support of FIG. 2;
FIG. 4 represents diagrammatically in vertical section a deep fryer equipped with a support according to a second embodiment;
FIG. 5 is a blown-up view of a portion of FIG. 4 illustrating the upper edges of the pan and of the casing equipped with a support;
FIG. 6 is a view on a smaller scale in elevation of the support of FIG. 5;
FIG. 7 is a profiled view of a support according to a third embodiment;
FIG. 8 is a front elevation view of the support of FIG. 7.
DETAILED DESCRIPTION OF THE INVENTION
The electrical cooking apparatus represented in FIG. 1 is deep fryer which comprises a metal pan 1 the bottom of which is heated by heating means 2 such as a shielded electrical resistance, a casing 3 produced in a plastic material capable of degrading at a high temperature such as, for example, that detected on the upper edge 4 of the pan 1 which is of the order of 180.degree. C. Such plastic materials are known, for example, under the name of A.B.S or polypropylene. In order to avoid degradation of the upper edge 6 of the casing 3, the said pan 1 rests inside the casing 3 on a series of supports 5 which are interposed in the said upper edge 6 and the upper edge 4 of the pan, and which thus leave between them spaces 7 (see FIG. 4) between the said upper edges in such a manner as to allow the circulation of air (arrows F FIGS. 1 and 4) around the pan between the said spaces and openings 8 made in the lower portion of the casing.
This circulation of air especially makes it possible to obtain not only a good ventilation of the space guaranteeing a
