Description

Die Erfindung betrifft eine Einbau-Glaskeramikkochplatte nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a built-in glass ceramic hotplate according to the preamble of claim 1.

Bei Glaskeramikkochplatten mit induktionsbeheizten Kochstellen ist es allgemein bekannt, die zugehörigen elektronischen Schalt- und Steuereinrichtungen mit Hilfe eines Gebläses zu kühlen. Die Kühlluft wird dabei unterhalb der Glaskeramikkochplatte gleichzeitig von vorne und von hinten her zur Mitte hin angesaugt und danach auf die links und rechts vom Gebläse platzierten Schalt- und Steuereinrichtungen umgelenkt. Im rückwärtigen Bereich wird der eine Teilluftstrom nach Passieren der zu kühlenden Schalt- und Steuereinrichtungen nach unten in einen zur Vorderseite hin führenden Ableitkanal umgelenkt, wo er an dessen Austrittsende mit dem anderen Teilluftstrom wieder zusammentrifft und in den Aufstellraum des Kochgerätes gefördert wird.In the case of glass ceramic hot plates with induction-heated hotplates, it is generally known to cool the associated electronic switching and control devices with the aid of a fan. The cooling air is sucked in below the glass ceramic hotplate from the front and from the back to the center and then redirected to the switching and control devices located on the left and right of the fan. In the rear area, after passing the switching and control devices to be cooled, the one partial air flow is diverted downward into a discharge duct leading to the front, where it meets the other partial air flow again at its outlet end and is conveyed into the installation space of the cooking appliance.

Der Erfindung liegt die Aufgabe zugrunde, die Kühlluftführung für die Schalt- und Steuereinrichtungen einer induktionsbeheizten Glaskeramikkochplatte konstruktionsmäßig und unterbringungsmäßig zu vereinfachen.The object of the invention is to simplify the design of the cooling air duct for the switching and control devices of an induction-heated glass ceramic hotplate in terms of construction and accommodation.

Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kennzeichnenden Teil des Patentanspruchs 1 zu entnehmen.The solution to this problem according to the invention can be found in the characterizing part of patent claim 1.

Vorteilhafte weitere Ausgestaltungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.Advantageous further developments of the subject matter of the invention are specified in the subclaims.

Durch die Erfindung wird eine induktionsbeheizte Einbau-Glaskeramikkochplatte geschaffen, bei der die Kühlluftführung für die empfindlichen elektronischen Bauteile integrierter Bestandteil der Montageeinheit "Glaskeramikkochplatte" ist.The invention creates an induction-heated built-in ceramic hob, in which the cooling air duct for the sensitive electronic components is an integral part of the assembly unit "ceramic hob".

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher beschrieben.
Es zeigen:

  • Fig. 1 eine Einbau-Glaskeramikkochplatte mit mehreren induktionsbeheizten Kochstellen in einer Draufsicht,
  • Fig. 2 diese Glaskeramikkochplatte in Verbindung mit einem Herd in Schnittdarstellung.
An embodiment of the invention is described below with reference to the drawing.
Show it:
  • 1 is a built-in glass ceramic hotplate with several induction-heated hotplates in a plan view,
  • Fig. 2 shows this ceramic hob in connection with a stove in a sectional view.

Die Glaskeramikkochplatte 1 ist von einem Einbau- und Schutzrahmen 2 eingefasst und hat vier induktionsbeheizte Kochstellen 3 bis 6. Im rückwärtigen Bereich der Glaskeramikkochplatte 1 ist eine Wrasenaustrittsöffnung 7 und 2 längliche Kühlluft-Ansaugöffnungen 8 und 9 vorgesehen, die in Breitenrichtung der Kochplatte verlaufend angeordnet sind.The glass ceramic hotplate 1 is enclosed by a built-in and protective frame 2 and has four induction-heated hotplates 3 to 6. In the rear area of the glass ceramic hotplate 1, a vapor outlet opening 7 and 2 elongated cooling air suction openings 8 and 9 are provided, which are arranged running in the width direction of the hotplate .

Wie Fig. 2 zeigt, ist diese Kochplatte oberhalb eines nur teilweise dargestellten Herdes 10 in einer sogenannten Arbeitsplatte 11 eingebaut. Gegen die Unterseite der Glaskeramikkochplatte 1 sind Induktionsheizungen 12, 13 für die einzelnen Kochstellen der Platte 1 angedrückt. Die oberseitigen Kühlluft-Ansaugöfffnungen 8 bzw. 9 gehören zu einem unterhalb der Glaskeramikkochplatte 1 angeordneten Luftführungsschacht 14, der in einen vertikalen und in einen horizontalen Luftführungsteil 15 und 16 aufgeteilt ist. Dem horizontalen Luftführungsteil 16 des Schachtes 14 ist die Luftansaugseite 17 eines Luftfördergebläses 18 (Radialgebläse) zugeordnet. Der Luftausblasseite 19 (Druckseite) des Gebläses 18 schließt sich ein parallel zu den Induktionsheizungen 12, 13 verlaufender Kühlluftkanal 20 an, in dem elektronische Schalt- und Steuereinrichtungen 30, 31 der Induktionsheizungen 12, 13 untergebracht sind. Am Ende 21 des Kühlluftkanals 20 erfolgt eine Aufteilung des Kühlluftstromes in einen vorderseitigen Ausblasluftstrom und in einen nach hinten geführten Rückluftstrom, wie durch Pfeile kenntlich gemacht ist. Der nach hinten geführte Rückluftstrom tritt im rückwärtigen Bereich zwischen Herd 10 und Glaskeramikkochplatte 1 aus und bildet eine thermische Trennung des Herdes (Back- und Bratofen) von der Glaskeramikkochplatte.As shown in FIG. 2, this hotplate is installed in a so-called worktop 11 above a stove 10 which is only partially shown. Induction heaters 12, 13 for the individual hotplates of the plate 1 are pressed against the underside of the glass ceramic hotplate 1. The cooling air intake openings 8 and 9 on the top belong to an air duct 14 arranged below the glass ceramic hotplate 1, which is arranged in a vertical and in a horizontal air duct part 15 and 16 is divided. The air intake side 17 of an air delivery blower 18 (radial blower) is assigned to the horizontal air guiding part 16 of the shaft 14. The air outlet side 19 (pressure side) of the fan 18 is followed by a cooling air duct 20 which runs parallel to the induction heaters 12, 13 and in which electronic switching and control devices 30, 31 of the induction heaters 12, 13 are accommodated. At the end 21 of the cooling air duct 20, the cooling air flow is divided into a front-side blow-out air flow and a return air flow guided to the rear, as indicated by arrows. The backward flow of return air flows out in the rear area between the cooker 10 and the glass ceramic hotplate 1 and forms a thermal separation of the cooker (baking and roasting oven) from the glass ceramic hotplate.

Durch die Integrierung der Kühlluftführung- und Fördereinrichtung in die induktionsbeheizte Glaskeramikkochplatte bilden diese Bestandteile zusammen eine kompakte Montageeinheit, die ohne großen Aufwand über Herde, Back- und Bratöfen bzw. separat eingebauten elektrischen Bedienungskästen montiert werden kann.By integrating the cooling air ducting and conveying device into the induction-heated glass ceramic hotplate, these components together form a compact assembly unit, which can be easily assembled using cookers, baking and roasting ovens or separately installed electrical control boxes.

Die oberseitigen Luftansaugöffnungen 8, 9 sind zweckmäßig durch ein die Ebene der Glaskeramikkochplatte 1 überragendes Steggitter 22 verkleidet bzw. abgedeckt. Durch eine solche Anordnung des Steggitters 22 wird sichergestellt, daß kein Überlaufkochgut in den Luftführungsschacht 14 gelangen kann. Die einzelnen Stege des Gitters 22 sind dabei in vorteilhafter Weise schräg gestellt und weisen nach hinten. Damit wird erreicht, daß die Kühlluft vornehmlich außerhalb des Kochbereiches der Glaskeramikkochplatte angesaugt wird.The top-side air intake openings 8, 9 are expediently covered or covered by a web grating 22 projecting above the plane of the glass ceramic hotplate 1. Such an arrangement of the web grating 22 ensures that no overflow cookware can get into the air duct 14. The individual webs of the grid 22 are advantageously inclined and point to the rear. This ensures that the cooling air is sucked in primarily outside the cooking area of the glass ceramic hotplate.
