Description

The invention relates to a steam pressure cooking pot, the lid of which is sealed with a clamp is designed such that it can be pressed against the pot, the clamping bracket being releasable from the lid and fixable on the edge of the pot is formed and provided with a central projection, which is a central in the cover opening is assigned.

It is known to cook food under overpressure because this cooking method saves time and heating energy are possible. To achieve an overpressure in the cooking vessel, it must be pressure-tight can be locked. Known pressure cookers use a bayonet lock type Locking of pot and lid, other known designs (for example according to the French Patent specification 642 452 and Swiss patent specification 131 581) stretch the cover pressure-tight the pot using a clamp. These brackets are locked into special holders or reach under the edge of the pot, and the sealing bracing of the lid with the pot is done via a central one Handle that by means of a screw thread the lid against the edge of the pot or one arranged there Seal presses.

The known types of steam pressure cooking pots have disadvantages.

Pots with bayonet lock require high manufacturing precision and are sensitive to the Sealing ring and have a recess because of the protruding cover when the cover is removed having segments ugly jagged edge, which makes it hardly possible to have such a Pot can also be used as a serving dish.

In the case of the saucepan according to French patent specification 642452, there is a central opening in the Cover is provided, which is assigned to a closure rotatably mounted on a threaded pin on the clamping bracket is. This opening only fulfills a safety function when the pot is opened Residual steam, shielded by an additional hood, can escape. Because this opening is tightly closed it cannot take over a safeguard against overpressure building up in the pot.

XQ If you want to achieve this security, you have to use this Pot as with the pot according to Swiss patent 131 558, an additional valve is provided will.

The invention is accordingly to the object

reasons to avoid these disadvantages, i.e. a steam pressure cooker should be created which can be used both as a visually appealing serving utensil as well as from the safety-related point of view From the standpoint of conventional devices

this type is superior without having to comply with particularly close manufacturing tolerances and the arrangement additional control valves are required in addition to the central cover opening.

This task is possible with a steam pressure cooker

a5 pot of the type mentioned according to the invention thereby solved that for sealing the central opening, the; ils valve seat is formed, the central projection is designed as a weight- or spring-loaded valve on the clamping bracket.

This training is advantageously achieved that despite low requirements in terms of Manufacturing tolerances, as far as the pot itself is concerned, those required for the lid and the pressure build-up Position is achieved to a certain extent automatically, the centering elements being advantageous at the same time take over the control for the desired and permissible pressure without an additional Valve is required.

In addition, after the end of the cooking process, the steam can be used sensitively and without endangering the Hands are lowered.

The pressure pot according to the invention is below with reference to the graphic representation of a Embodiment explained in more detail. In this illustration shows

F i g. 1 shows a section through a pot with the lid open and

2 shows an enlarged section through the cover screw connection of the pot according to FIG. 1.

As in Fig. 1 is shown, the pot lid 2 with its sealing ring 3 by means of the bracket 4, the bcidscitigc ends 12 in slots 13 of the pot side wall are held, and the handwheel 8, »which the threaded pin 7 actuated in the sleeve 10, pressed against the edge 18 of the pot 1 in a sealing manner. Here It is important that the temple ends 12 are symmetrical on both sides and of the same length into the slots 13 are inserted and it is structurally prevented with certainty that, e.g. on one side, too little There is an overlap. In this case, there would be a danger under cooking pressure, i.e. internal overpressure the sliding of the bracket.

For a more detailed description of the function of the device is explained below, as with the pot after F i g. 1 a cooking process is in progress.

Pot 1, lid 2 and bracket 4 (with attached screw connection) are initially separated before.

If the pot is filled with food, the lid 2 is centered in the same way as a normal saucepan inserted the edge 18 of the pot. Then the bracket 4 is gripped on the handwheel 8 and initially one side inserted so far into one of the two-sided slots 13 of the pot wall that the bracket lower and insert it into the opposite slot by sliding it sideways.

This ensures that both temple ends 12 are symmetrically inserted sufficiently far into the slots are, the cover 2 has a central opening 11, which ensures that the pot after screwing of the bracket can only achieve overpressure when cooking if the bracket is centered. He sits not centered on, the pin 9 prevents sealing of the opening 11 by not being in the opening engages and a seal cannot enter even when screwed tight, since the pin 9 then sits next to the opening 11 on the cover.

The pot cannot become tight if it is improperly closed. To facilitate the Orientation when closing the lid are attached to the bracket 4 markings 23, which when closing directly on the edge of the slots »5 13 must lie so that the pin 9 can click into place. If the bracket 4 is properly seated, it is twisted to close the pot, the handwheel 8, which is guided in the threaded bushing 10 of the bracket will.

In the embodiment of a steam cooker described above, bracket 4 and lid 2 are separate parts that are independent of one another. This offers the advantage of being able to use the pot as a normal saucepan without a handle. Here, even the seal ring could Vertika 3 d away "from the lid end of a, about 1 SfiReU W makes these arrange- is ^way your" Wichts- or spring-loaded valve. ^Now you can see the centering of the bracket on the lid of lid 2 with a center plate 29
