Abstract

The pressure cooker has a safety valve (3) and a lid lock (4) and is designed so that the cooker can be opened without danger. The safety valve (3) is positioned in the lid and automatically opens with excess pressure and lets steam out. The locking device ensuring that the lid lock (4) is kept closed when the safety valve is closed consists of a cam plate (6) fixed to the safety valve (3). The cam plate (6) moves a spring-loaded thrust rod (7) into an opening (9) in the lid lock (4).

The lid lock is only unlocked again when the lid safety valve is opened, i.e. the steam pressure is guaranteed to be reduced is.

Beim Öffnen des Deckelverschlusses kommt die Öffnung 9 in eine andere Position, so daß die Schubstange 7 bei ganz geöffnetem Deckelsicherheitsventil nicht bewegt werden, d.h.When opening the lid closure, the opening 9 comes into another Position so that the push rod 7 is not when the cover safety valve is fully open moved, i.e.

bei offenem Deckelverschluß ist das Deckelsicherheitsventil nicht schließbar.when the lid lock is open, the lid safety valve is not lockable.

Durch die Mulde 11 im Deckel 1 wird gesichert, daß das Deckel sicherheitsventil 3 unter Druck nicht herausgenommen werden kann, da die Rändelschraube 12 ganz in der Mulde 11 liegt und somit nicht herausgedreht werden kann. The trough 11 in the cover 1 ensures that the cover safety valve 3 cannot be removed under pressure, since the knurled screw 12 lies entirely in the trough 11 and thus cannot be unscrewed.

Druckkochkessel Die Erfindung betrifft einen Druckkochkessel mit einem Deckelsicherheitsventil und einem Deckelverschluß. Pressure cooking kettle The invention relates to a pressure cooking kettle a lid safety valve and a lid lock.

Bei einem unter Dampfdruck stehenden Kochkessel besteht beim Öffnen des nach oben schwenkbaren Deckels die Gefahr, daß plötzlich sehr viel heißer Wasserdampf austritt oder der Deckel hochschlägt. Die Bedienungsperson kann sich dabei verbrühen oder vom hochschlagenaen Deckel verletzt werden. Aus diesem Grunde muß dafür Sorge getragen werden, daß der Deckel erst dann zum Öffnen freigegeben wird, wenn der Dampfdruck genügend abgebaut ist.If the kettle is under steam pressure, there is a problem when it is opened of the lid that can be swiveled up, there is a risk that suddenly a lot of hot water vapor leaks or the lid hits up. The operator can get scalded or be injured by the lid being thrown up. Therefore care must be taken be worn that the lid is only released for opening when the The vapor pressure has been reduced sufficiently.

Hierzu sind Deckelverschlüsse vorgeschlagen worden, die zunächst das Öffnen des Deckels nur um einen geringen Spalt erlauben. Dadurch wird zunächst der Dampfdruck abgebaut und danach in einer zweiten Stufe das vollständige Öffnen des Deckels ermöglicht. Der durch den Spalt ausströmende Wasserdampf kann aber für die Bedienungsperson weiterhin eine Gefahr bedeuten.For this purpose, cover closures have been proposed that initially use the Allow only a small gap to be opened. This initially creates the Vapor pressure is reduced and then, in a second stage, the complete opening of the Lid allows. The water vapor flowing out through the gap can, however, be used for the Operator continue to represent a hazard.

Die Erfindung hat sich zum Ziel gesetzt, einen Druckkochkessel möglichst gefahrlos öffnen zu können.The invention has set itself the goal of a pressure cooking kettle as possible to be able to open safely.

Dabei wird von der Tatsache ausgegangen, daß sich im Deckel ein Deckelsicherheitsventil befindet, welches bei Überdruck automatisch öffnet, und Dampf ausströmen läßt, um den kritischen Dampfdruck abzubauen.This is based on the fact that there is a cover safety valve in the cover is located, which opens automatically at overpressure, and lets steam flow out to reduce the critical vapor pressure.
