Descrizione Description
L'invenzione concerneuna piastra di cottura elettrica-del genere precisato nella prima parte della rivendicazione 1. The invention relates to an electric cooking plate of the kind specified in the first part of claim 1.
Nelle piastre di cottura di questo genere, ad esempio con riscaldamento per irraggiamento di piastre di vetro-ceramica, ? previsto usualmente un avvolgimento di riscaldamento che ricopre in ampia misura la zona-di cottura. Nella detta zona di cotitura si trova-un termostato Per intensivare l inizio delia-cottura si cerca di far funzionare il riscaldamento inizialmente con-una-maggiore potenza riscaldante. Questa maggiore-potenza riscaldante-viene pero trasmessa effettivamente sulla-pentola soltan to quando-il fondo-di -questa ? piano. Nel-caso di fondo non piano della pentola, il termostato inter rompe il riscaldamento-iniziale pi? -potente. E' stato riscontrato -in pratica, che con un aumento della potenza di riscaldamento di un?unico avvolgimento riscaldante ricoprente la zona di cottura, ad esempio da 1500 W a 1800 W non si ottiene l'intensivazione dell'inizio di cottura, poich? il termostato-estendentesi-trasversalmente all'avvolgimento riscaldante, a-seguito-dei cattivo passaggio di-calore-sul fondo bombato delia pentola ne1 caso dell'aumentata potenza_riscaldante disinserisce molto-presto l'intero riscaldamento-, interrompendo l'Linizio di cottura L?'intenzione si ? posta il compito di perfezionare una piastra di cottura elettrica del genere precisato nella prima parte della rivendicazione 1, in-maniera che anche con fondi nonspiani delle pentole sia reso-possibile senza problemi un tinizio Rivendicazioni In cooking plates of this type, for example with radiant heating of glass-ceramic plates,? usually provided for a heating winding which largely covers the cooking zone. In said cooking zone there is a thermostat. To intensify the start of cooking, an attempt is made to initially make the heating work with greater heating power. However, this greater heating power is actually transmitted to the pot only when the bottom of it is. floor. In the case of a non-flat bottom of the pan, the thermostat interrupts the initial heating pi? -powerful. In practice, it has been found that with an increase in the heating power of a single heating winding covering the cooking zone, for example from 1500 W to 1800 W, the intensification of the start of cooking is not obtained, since the thermostat-extending-transversely to the heating winding, as a result of bad heat transfer on the convex bottom of the pot in the case of increased heating power, switches off the entire heating very quickly, interrupting the start of cooking L ? is it going to you? the task of perfecting an electric cooking plate of the kind specified in the first part of claim 1, in such a way that even with non-flat pan bottoms it is possible without problems a start.
1. -Piastra di cottura elettrica, preferibilmente piastra di cottura di vetro-ceramica, con un avvolgi metto riscaldante ricoprente la zona di cottura, caratterizzata dal fatto che ? previsto almeno un avvolgimento riscaldante supplementare (2), il quale circonda in ampia misura almeno nella periferia della zona di cottura l'avvolgimentoriscaldante.(l) ricoprente la.zona-di cottura ed ? inseribile preferibilmente separatamente da quest.'ultimo avvolgimento-riscaldante. 1. -Electric cooking plate, preferably glass-ceramic cooking plate, with a heating wrap covering the cooking zone, characterized by the fact that? at least one additional heating coil (2) is provided, which largely surrounds the heating coil (1) covering the cooking area at least in the periphery of the cooking zone. which can preferably be inserted separately from the latter heating-winding.
2. Piastra di-cottura elettrica,-secondo.la rivendicazione-1,-caratterizzato,dal fatto che la potenza riscaldante dell'avvolgimento riscaldante supplementare (2).? notevolmente minore della potenza riscaldante dell'altro.avvolgimento.riscaldante (l), preferibilmente nel apporto di 1 : 5. 2. Electric cooking plate, according to claim 1, characterized in that the heating power of the additional heating winding (2). considerably lower than the heating power of the other heating winding (1), preferably in the contribution of 1: 5.
3.-Piastra di cottura elettrica, secondo le rivendicaz?oni 1.e 2, caratterizzata dalfatto che entrambi gli avvolgimenti riscaldanti (1, 2) sono inseribili insieme mediante un unico organo di azionarnento,.preferibilmente alla massinia posizione di potenza. 3. Electric cooking plate, according to claims 1 and 2, characterized in that both heating windings (1, 2) can be inserted together by means of a single operating member, preferably in the maximum power position.
4.-Piastra di cottura elettrica secondo le rivendicazioni precedenti, caratterizzata dal fatto che l'avvolgimento riscaldante (l) ricoprente la zona di cottura ? disposto in forma di due gruppi (5, 6) di serpentine semicircolari concentriche (5', 6') e dal fatto che l'avvolgimento riscaldante supplementare (2) circonda le dette zone di riscaldamento in forma circolare. 4.-Electric cooking plate according to the preceding claims, characterized in that the heating coil (1) covering the cooking zone? arranged in the form of two groups (5, 6) of concentric semicircular coils (5 ', 6') and in that the additional heating winding (2) surrounds said heating zones in a circular form.
