OBJECT OF THE INVENTION.
[0001] As is expressed in the title of the present of the present descriptive report, the following invention consists of a cover for the lodging and the terminals connecter of the electric and/or electronic system in cooking plates, which is useful for its incorporation in the cooking plates of the glass-ceramic heater elements, by radiation, induction and/or halogen, so that the cover remains under the ceramic glass.
[0002] By means of the cover that is presented, a whole totally tight is obtained, impeding the humidity pass to the components that are lodged in its interior and besides, making easy the connection among all the terminals of the electronic system, since it has a connecter that incorporates all the connection terminals aligned so that by a simple pressure, the fast connection among all them is allowed, connecting it with the terminals placed in the own cover that also are perfectly aligned.
[0003] In the other hand, in the connecter in which all the terminals remain aligned, all the extremes of the cables remain integrated into the own connecter body during the injection process for its manufacture and besides, the connecter has some lateral projectings that are backed to some respective clefts in the cope of the support body of the cover where it is placed, and a whole of perimetric strengthenings that allow a closing perfectly tigth, so that the internal part of the cover remains insulated from the humidity.
[0004] To collaborate in a totally tight closing, the upper base of the support body of the cover, on which the lid body is placed, has a pair of projectings according to all its outline.
FIELD OF APLICATION.
[0005] The cover for the lodging and the connection of the terminals of the electronic system in cooking plates is applicable for insulating the components of the electronic system from the cooking plates and the terminals in which the corresponding connecter is connected, remaining the cover under the ceramic glass, and being the heater elements by radiation, induction and/or halogen, so that the cover acts as an protecting element for the electronic system, both acting as a thermic barrier and as a tigth element for avoiding the humidity pass that can cause an anomalous working of the whole.
BACKGROUND OF THE INVENTION.
[0006] Conventionally, among the different domestic appliances for cooking, we can quote those that have some calorific centres of gas or electric, which are controled by the corresponding activation controls for the user for which, the activation controls are joined with their corresponding valve of gas pass or electric switch. Thus, the cited union is realized through several ways, being one of them by means of a cardan transmission that consists on some telescopic bars for the regulation of the distance among them, with some ball-and-socket joints in their extremes for the fixing of the union elements.
[0007] In the other hand, as the activation controls of the calorific centres must have a position of security for impeding its free turn, the rod or spindle of the controls is supported by a spring that pushes it to the exterior, so that a projection of the same one must be lodged in a complementary mortise of the body that is fixed to the appliance.
[0008] With regard to the glass-ceramic plates that are usually utilized, they are placed in a lodging that is realized to that end in the hob and they can have some controls although usually, they have not any controls, being they placed in the frontal part of the oven for the control of the calorific centres.
[0009] Besides, in this kind of cooking systems, the apparatus must incorporate an electronic system for the control and working of the heater elements with the corresponding connections among all the system components and feed sources, so that all the system remains close to the own glass-ceramic plate and therefore, the system must be protected before the high temperatures that it must resist and before the humidity for avoiding the possible anomalous behaviour of the system.
[0010] Thus, the electronic control system is lodged in a box or cover of plastic material, that acts as a thermic barrier and as a tight body against the humidity, so that the several connecters, in which the terminals of the several connection cables will be connected, remain in the cover.
[0011] The several connecters are distributed by several zones of the cover, and the terminals of the corresponding connection cables are manually connected. This motive represents serious drawnbacks because of the few space for the manipulation of the same ones that makes difficult the connection operation and besides some little particles can come off the own cables because of their manipulation, so that these particles can dirty the lodging of the support base of the electronic tracks that can cause anomalous behaviours of the electronic components and consistently, an erroneous working of the cooking apparatus.
[0012] Besides, the entrance pass of all the cables to the interior of the box or cover is blocked up by a tight joint, but because of the cables conglomerate, it is difficult to obtain a closing totally tight, and although it is avoided the pass of any liquid that can have been spilt, it is not obtained the appropiate tight closing against the humidity that also can act on the electronic components, so that these components have not the appropiate behaviour, being sometimes neccesary the technical asistance for their repair.
DESCRIPTION OF THE INVENTION.
[0013] A box or cover for the lodging of the electric and/or electronic components and terminals connecter of the same one in cooking plates is described in the present report, being of the kind of those covers that are assembled under the ceramic glass, acting as a thermic barrier and as a tight element in whose interior the electronic control system of the heater elements is lodged and connected, being made up of a support body, that is blocked up by the corresponding lid, one of whose lateral sides has a cope in which it is defined a seat base of bigger width than the upper base on which the closing lid is placed, so that the connecter, which is endowed of the aligned connection terminals, is placed on the cited base that is related to the lateral cope.
[0014] The lateral surfaces of the cope of the support that contains all the electronic components of control in relationship to the internal part of the addition of thickness that defines upperly, has each vertical clefts.
[0015] Likewise, the upper base of the support that contains the electronic components, in which the connection of the electronic system is materialized, has a pair of projections so that the closing lid is placed on them, materializing a perfect tight closing and also avoiding the humidity pass.
[0016] The connecter that carries the terminals of the connection cables is defined by an injection body of plastic material and/or resins in which both the connection cables and the terminals, with a little play for making easy their connection and above all their disconnection if it is necessary, are integrated so that they remain in the extreme part of bigger width than the seat zone on the base of the cover support, for allowing their connection on the terminals that are aligned in the own support in relationship to the internal part of the cope of its internal side.
[0017] Thus the free extremes of the terminals remain free in the injection process for maintaining the mechanical and elastic properties of the terminal for the assembly and disassembly of the connecter whole easily.
[0018] Likewise, the connecter, in relationship to the internal zone of seat on the support base, has a pair of lateral projections that are inserted in relationship to the clefts of the lateral surfaces of the lateral cope of the support, so that thus the connecter body is placed, being fixed and avoiding any kind of stress on the terminals, in the case of causing a traction effort on the connection cables.
[0019] In the other hand, the connecter has a whole of perimetric strengthenings in relationship to the seat zone on the base of the lateral cope that is made on the own support, so that they collaborate in the own tight closing with the lid.
[0020] In order to complement the description which is done hereinafter and for the purpose of providing a better understanding of its characteristics, the present descriptive report is accompanied by a set of drawings, in whose figures the most significant details of the invention are represented in an illustrative and not limitative way.
