RADIANT STOVE

The invention relates to a radiation focus with a locking device for the oven door, whereby the door can be unlocked at will while switching off the HF radiation. It is based on the DT-AS 1 848 676, in which a radiation stove with control of the cooking processes by a program switch is described. By means of arbitrary unlocking of the oven door while switching off the high-frequency radiation at the same time is to be achieved, the punch cards from every sequence position to be able to bring into the starting position or into the end position.

Usually, however, the radiation stove is equipped with a timer equipped to switch on the radiant energy and to set the cooking time. Will be a menu with different Prepared dishes that require different cooking times, according to the current state of the art, one was forced to To add more food, set the timer to zero so that the door can be unlocked and opened. Then it has to Timer can be reset, but taking into account the food that has been inserted from the beginning, the one that has expired up to that point Had to take into account the cooking time.

The invention is based on the object of being able to switch off the radiant energy independently of the timer, namely by

an arbitrary unlocking of the oven door, as indicated in the other context by DT-AS 1 148 676.

In solving this problem, it is proposed according to the invention that in the circuit leading via a timer for the supply of the 'HF generator at least one isolating switch is arranged, which is dependent on the locked state of the oven door is actuated. By unlocking the oven door mechanically or electrically, the circuit breaker opens and interrupts the Circuit for supplying the HF generator. The timer does not need to be operated.

The circuit breaker is expediently through a mechanical connection actuated by rod parts of the locking device to the circuit breaker. ,. ".

An embodiment of the invention is shown in the drawing an electrical circuit is shown. Between the power lines R and Mp run a circuit 2, which is led via a timer 17. In this circuit 2 there are two mechanically operated Isolating switch 22 and 23. The timer 17 has three contactable, namely the contactable 24 and 26 for switching on the HF generator 27 and a KontaJitfaar 25, which is in the branch line 2a for the power supply of the Mo% drs M des Zeitschaltw ^ jpkes 17 is located. When setting a cooking time, all three contactables 24, 25 and 26 are closed.

Behind a door safety switch 20 in the circuit 2, a locking circuit 3 goes off, which is operated by a pushbutton switch 31 and an electromagnet 33 leads. The electromagnet 33 excited when the pushbutton switch 31 is pressed carries one Toggle switch 39 with a so-called ballpoint pen-like effect for locking and unlocking the oven door by repeatedly pressing the button.

Your flelctromagnet 33 is a pincer-like locking device assigned as it is described j η of CS 2 140 230.

Here, the electromagnet 33 actuates an actuating rod 36 or a rod part _t a cone 34a for closing a pair of pliers consisting of two levers 34b, which locks itself behind the locking pin 35 of the oven door 40 when the cone 34a is controlled to the right. The respective switching position of the control rod 36 is via a mechanical connection 37 to the jointly operated disconnectors 22 and 23, which are open when the door is not locked and which close when locked.

When the door is closed and locked by pressing the push button switch 31, by setting the timer 17 the Radiant energy of the stove are effectively switched on, as the door safety switch 20 and the two isolating switches 22 and 23 are closed. If a food needs to be added after part of the set cooking time has elapsed, all that is required is a pressure on the push button switch 31, by renewed energization of the electromagnet 33 and switching over the changeover switch 39 to reset the control rod 36 to the left, with which the door 4O is unlocked. From this unlocking movement namely the isolating switches 22 and 23 open via the mechanical connection 37, whereby the circuit 2 for the supply of the HF generator 27 is interrupted, although all contactables of the timer 17 are still closed. After the hearth door is closed again, the push button switch 31 can be actuated again to lock the door, which then closes the door Isolation switch 22 and 23 the cooking mode is resumed for the remaining cooking time set.
