DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a device for supporting the mechanical and electrical members of an electrical appliance, particularly a toaster.
The invention also relates to various improvements made to said mechanical and electrical members.
DESCRIPTION OF RELATED ART
Known toasters generally comprise three main parts inside the control box which are distinguished in the following manner:
a metallic support which serves as a rigid base to which the electrical members and the mechanism are attached;
the electrical members (timer, switch, power-supply cable attachment) consisting of insulating and metallic components;
the electrical connections consisting of insulated flexible conductors which connect the electrical members with the aid of connections generally produced with clips and tongues.
This construction gives rise to a large number of components which can be fitted only by manual operations; in particular, the flexible cabling and the snap connections. Moreover, each electrical member must be efficiently insulated from the toaster housing. Furthermore, all the electrical and mechanical members must be adjusted after having been fixed to the toaster.
Therefore, current toaster designs are complicated and costly.
SUMMARY OF THE INVENTION
The present invention aims to remedy the drawbacks of known embodiments by creating a device for supporting the mechanical and electrical members, which permits both a reduction in production and fitting costs and an increase in reliability.
The invention thus relates to a device which can be fitted to a toaster of the vertical type, comprising a housing containing a support for supporting the slices of bread and at least one heating resistor, means being provided for commanding the displacement of the support for the slices of bread, means for locking said support in a low position, means for electrical power supply to the heating resistor, means for adjusting the heating temperature of said resistor and means for cutting-off this electrical power supply after a certain period of heating.
According to the invention, said device comprises a plate in electrically insulating material on which the abovementioned means are fixed, this plate forming an insulating support for all the electrical members of said means, said means being preadjusted and said plate comprising means for fixing it to one of the faces of said housing.
This plate makes it possible to fit thereon, in the factory, all the mechanical and electrical control members or means of the toaster.
The fact that the plate forms an insulating support for all the electrical members dispenses with the need to provide individual electrical insulation for each member, which increases their cost.
Moreover, all these members are preadjusted on the plate before the latter is fixed to the housing of the toaster, which is much more convenient.
According to an advantageous version of the invention, the plate is in plastic material and comprises protuberances or tongues molded in the plastic material and projecting on one of the faces of the plate, these protuberances or tongues being shaped in order to receive and ensure the fixing of conducting or mechanical elements by translation of the latter perpendicularly to the plate.
This plate makes it directly possible to receive the bare electrical members by virtue of the insulating nature of the material and of the provision of forms possible in molding. The electrical connections may be produced with cut-out metal strips which may be fitted in an automatic manner due to the dimensional stability of these components. The positioning of a contact on these strips and the provision of form thereof makes it possible to embody the switch function without any other attached component and without connection.
Moreover, this plate ensures the positioning and the guiding of the mechanism (for example that controlling the slide of a toaster) in a simple manner; the provision of tongues in the plastic material permits economic assemblies by means of snapp
