Definitions

  • the invention relates to a pot for cooking cookware or the like, consisting of a vessel and a lid, with a device for displaying the inner pot pressure, which on the pot wall, i.e. the lid or the vessel wall is provided.
  • the object of the invention is therefore to create a pot of the type mentioned, in which in particular the previously mentioned disadvantages are avoided and a reliable pressure display takes place.
  • this object is essentially achieved in that an area of the pot wall is formed by a flexible membrane, which is assigned a device for transmitting the pressure-related deflection of the membrane to a display element.
  • the membrane is thus directly or indirectly integrated, with its edge tightly connected or clamped in to the wall of the pot, and only subjected to pressure-related deflection without opening, as is the case with spring-loaded display valves Case is.
  • the membrane allows the respective pressure state in the interior of the pot to be transferred to a display instrument arranged outside the cooking space, for example on the lid.
  • the membrane thus continuously separates the cooking area from the display area; only their deflection movement caused by the variable inner pot pressure is used for the display of the pressure state in the inside of the pot.
  • the function of the membrane is not affected by the boiling of the food to be boiled, since the membrane movement is solely dependent on pressure.
  • the side of the membrane facing the inside of the pot is almost smooth and can therefore be easily cleaned by hand or by machine after using the pot.
  • the membrane is made in one piece from the wall of the membrane itself.
  • the pot membrane can also permanently close an opening in the pot wall, which can be achieved, for example, in that the membrane, covering the opening, is welded or soldered pressure-tight to the pot andung.
  • the membrane is part of a e.g. sleeve-shaped housing that fits into the opening of the pot wall, e.g. by screwing and e.g. can be used pressure-tight due to the interposition of a seal.
  • the membrane can be formed in one piece with the housing or welded, soldered, braced or otherwise connected pressure-tight to the housing.
  • the membrane can simply be inserted into the opening of the pot wall in that the housing projects with a threaded section inwards through the opening of the pot wall and a securing element is screwed onto the threaded section. So the housing can be reliably but detachably fixed to the wall of the pot.
  • the transmission device can in principle be mechanical, opto-mechanical, electro-mechanical, electro-optical or electronic in nature.
  • the means for transmitting the deflection of the diaphragm on a display element can be mechanically, for example, thereby be realized that a acted upon by the diaphragm pot outside side follower or other equivalent means is provided for transmission of movement and are, its or their pressure-induced, • resulting from the diaphragm movement is implemented in the movement or other setting of a display element, for example a scale pointer.
  • the plunger can be guided on a carrier fixed to the housing.
  • the plunger can be spring-biased towards the diaphragm in the direction of the diaphragm.
  • the carrier is designed as a guide rod and the plunger as a sleeve that overlaps the guide rod.
  • the support is conveniently held via a pot-parallel support plate, which is connected to the housing, e.g. by crimping.
  • the display element can be moved on the carrier plate, e.g. be rotatably mounted.
  • the carrier plate can also carry a scale division for the display element.
  • the invention further proposes to form the housing in a sleeve-shaped, preferably essentially hollow-cylindrical, and an opening of the housing facing away from the pot, for example by crimping, by means of a display window having, for example, a scale division and a pot-facing opening of the housing by means of the membrane being water and to close vapor-tight.
  • the transmission device is preferably arranged inside the housing in a chamber-like interior that is sealed off on the one hand by the shop window and on the other hand by the membrane.
  • the carrier plate or the shop window can also, especially if the transmission device is an electronic transmission device, as e.g. digital display element.
  • a preferably adjustable stop can be assigned to the inside of the pot.
  • the stop can be part of the securing element for the housing, for example.
  • the membrane is set back outwards relative to the plane of the cup opening, i.e. e.g. at a distance from the end of the housing on the inside of the pot, a vapor cushion is created in front of the membrane, which serves to protect the membrane against contact with the food to be cooked.
  • the housing can simultaneously serve for handling the vessel and in particular the lid
  • the housing is preferably enclosed by a handle button made of heat-insulating material.
  • the handle knob can be guided at least to a limited extent on the housing in order to be able to perform further functions, for example display switch-on or switchover functions or visualization of the temperature, the cooking time or the like. Measured values.
  • the membrane preferably extends essentially in or parallel to the plane of the pot wall and preferably consists of metal, in particular stainless steel or a bronze alloy.
  • 1 is a vertical section in a plane containing the axis of symmetry of a device according to the invention for displaying the inner pot pressure
  • FIG. 2 shows a section of the display device according to section line A-B of FIG. 1,
  • FIG. 3 is a top view of the display instrument of FIG. 1; 4 shows a detail section according to section line CD of FIG. 1,
  • FIG. 5 is a partial view in the direction G of FIG. 1,
  • Fig. 6 is a partial view from the direction H of Fig. 1, and
  • FIG. 7 shows a courtyard horizontal section along the section line E-F from FIG. 5.
  • the pot wall 1 in the special case, for example, the top wall of a pressure cooker, has an opening 2 which is permanently closed by a membrane 3.
  • the membrane 3 is a round, clamped on its edge, essentially flat, possibly wave-shaped plate, preferably made of metal, for example made of stainless steel or a bronze alloy.
  • the membrane 3 is welded or soldered into a sleeve-shaped, essentially hollow-cylindrical housing 4 in a pressure-tight and vacuum-tight manner and lies essentially in or parallel to the plane of the cup wall 1.
  • the housing 4 has a tapered threaded section 5 on the cup wall side. with which it can be inserted from the outside through the opening 2.
  • a securing element 7 is screwed onto the threaded section 5 from the inside, so that the housing 4 is pressed with a ring shoulder provided at the transition of the threaded section 5 to the rest of the housing wall against a seal 8 designed as an O-ring, in a pressure-tight and vacuum-tight manner. which is arranged in a circumferential groove delimiting the opening 2.
  • the membrane 3 is, depending on the inner pot pressure 10, more or less large deflections in the range of a few tenths of a millimeter, while it is firmly clamped on its peripheral edge.
  • the securing element 7 forms a certain protection of the membrane 3 against contact with the food.
  • the diaphragm 3 directly as a one-piece part of the pot wall 1 or to weld or solder directly to the pot change 1, covering the opening 2, so that the diaphragm 3 represents a partial area of the pot wall 1 and the s pot pressure 10 is exposed.
  • the housing 4 would not, as in the exemplary embodiment shown in the drawing, protrude through the pot opening 1, but would be fastened on the outside of the pot opening 1, covering the membrane area.
  • the housing 4 there is a mechanical transmission device which converts the deflection of the membranes 3 into the deflection of a display element 21, in this case designed as a scale pointer.
  • the housing 4 is closed at its end facing away from the pot by a crimped shop window 9.
  • the transmission device has a plunger 11, which rests against a rod-shaped support element 12 by means of a spring 23 and rests on the end face of the outer surface of the membrane 3.
  • the plunger 11 is sleeve-shaped and, with its end facing away from the pot, comprises the end of the carrier 12 facing the pot, on which the spring 23 is also supported.
  • the spring 23, acts on the inner surface of the end wall of the plunger 11 abutting the diaphragm 3.
  • an axially parallel elongated hole 13 is provided, through which a pin 15 fixed on the carrier 12 engages.
  • This will the movement path 14 of the plunger 11 is limited relative to the carrier 12.
  • the pin 15 also prevents the plunger 11 from rotating relative to the carrier 12 and forms the axis of a pivoting lever 16.
  • the limited movement path 14 is adapted to the deflection capacity of the membrane 3.
  • the plunger 11 carries a further outwardly projecting pin 17 which engages in an opening of the pivot lever 16 at a distance from the pin 15. If the plunger 11 moves by the movement path 14, the pivot lever 16 is pivoted through an angle 18.
  • the swivel lever 16 has a toothing 19 on its upper edge, which interacts with a pinion 20 which is rotatably mounted in a carrier plate 6 by means of axis 22.
  • a pinion 20 which is rotatably mounted in a carrier plate 6 by means of axis 22.
  • the display element 21 designed as a scale pointer.
  • the securing element 7 has a central stop 24 for the diaphragm 3 in order to prevent the diaphragm 3 from bending too far inwards when the inside of the pot is under pressure.
  • the housing 4 can be surrounded by a handle knob 26 made of heat-insulating material, so that the housing 4 with the transmission and display device accommodated in its interior 25, which is sealed off from moisture and vapor tightness, into the vessel or Pot handle is integrated.
  • the knob 26 leaves the view of the display window 9 clear.
  • the inner pot pressure 10 acts on the inner surface of the membrane 3 without opening any opening.
  • the membrane 3 is moved in the direction of arrow 10; due to its clamping on the outer edge, it only bulges outwards against the tappet 11, which therefore also moves in the direction of the pressure application 10.
  • the movement of the plunger 11 is transmitted to the display element 21 by the display technology in the manner described. If the inner pot pressure drops, the plunger 11 and the diaphragm 3 move back into their starting position with the cooperation of the spring 23. Accordingly, with the cooperation of the spring 23, the transmission mechanism with the pivot lever 16 and the display element 21 is also reset. If a vacuum occurs in the interior of the pot during rapid and strong cooling, the membrane 3 tries to bulge inwards. A buckling of the membrane 3 is avoided, however, by the stop 24, which may be adjustable and adjustable. The membrane 3 can therefore only move overall between the stop 24 and the plunger 11 in its outermost position delimited by the elongated hole 13. Overexpansion of the membrane 3 is avoided.
  • electrical or electronic components and display parts can also be provided, for example an electromechanical and / or electronic conversion of the display pulses supplied by the membrane 3 into a visible one Convert display, eg also a digital display.
  • a visible one Convert display eg also a digital display.
