Description

Pressure cooker cover

This creation is about a pressure cooker cover. In particular, the present invention relates to a pressure cooker lid having a pouring edge, which can also be used as a conventional pot.

The pressure cooker is a cooking device that operates by increasing the boiling point. These pressure cookers have a cover containing a pressure relief valve through which the desired operating pressure of the pot is determined. Therefore, the food can be cooked in a shorter time with a temperature of generally about 120 °C.

The pressure cooker is formed as a pressure vessel and must meet high safety requirements. Conventional pressure cookers typically include a pan having a peripheral groove or the like in which a fitting cap can be latched. Since the latch member is disposed on the pan, the pressure cooker is generally not suitable for use as one of the common cooking pots for decompression cooking.

Thus, the European patent EP 1 416 837 proposes a pressure cooker lid comprising a claw bent in a U-shape by means of which the lid can be latched on the pouring edge of a "normal" shaped pot . The pot having a pouring edge is more suitable for use as a conventional cooking pot. One disadvantage is that the entire cover of the pot must be changed for normal decompression purposes. According to the teachings of the documents mentioned above, the latching pawl can be removed for cleaning. However, this is relatively complicated, since one of the nuts on the bottom side of the cover must be removed for this purpose. To do this, you must generally use a tool. The cover having the claws is also difficult to use as one of the ordinary cooking lids in the unlocked state. Therefore, need There is another type of cover that can be used for the decompression operation of the cooking pot. In addition, the design of the cover is relatively tricky and complicated.

German Utility New Case DE 20 2009 015 975 proposes: a cooking vessel and a cooking vessel system kit (specifically, one for all energy types and feed/oven types and different cooking temperatures and pressures, decompression and pressurization, internal or An externally heated cooking vessel, preferably a steam pressure cooking vessel, having a container for receiving food to be cooked and having a container that can be placed on the container and latched in a pressure tight manner in a number of different ways to a functional cover of the container; and a pressure relief valve system corresponding to the associated adjustment and another suitable function, wherein the cooking vessel is composed of a cover module and a pot module, the cover module having a seal The functional cover and the edge of the pan having a cold handle, and a system is joined to the pan module via a mechanical, fixed and sealed interface.

The design of the cooking vessel consists of a cover module having a functional cover that is releasably coupled to the lid via a fastening nut or release screw, and the combination is sealingly connected to the edge of the pan, the edge of the pan being A cover is formed to form an interface to the pot module.

According to the European patent EP 1 342 440, a steam pressure cooking device having a lid module is proposed, which consists of a container and a lid intended to be placed and latched on the container to form a closed cooking. a seal; one or more claws for latching the cover to the container; and a member for driving at least one of the claws between a latched position and an unlocked position, wherein there is an intended placement and Removably securing at least one module to the cover, wherein the module includes at least one control device for latching/unlocking the cover and the container and at least one of: a minute counter, A pressure control valve, a pressure sensor, a temperature sensor, a pressure relief valve, a member for ensuring closure/opening or a bi-stable operating device.

In the present application, the mechanical-electromechanical interface is disposed between the clamping module and the closure/cover; The clamping module contains the mechanical and sensing controls of the pan and thus contains most of the contacts to the closure and the cover. The clamping module is sensitive to water.

The purpose of this creation is to provide a pressure cooker cover whose manageability is improved.

In particular, one of the purposes of this creation is to convert the cover into a normal cover without a latch in a simple manner. It also simplifies assembly and cleaning of the cover.

The purpose of the present invention is solved by a pressure cooker cover as in any one of the independent technical solutions. The preferred embodiment and development scheme of the present invention are derived from the respective subordinate technical solutions.

The present invention relates to a pressure cooker lid, in particular a lid that can be latched onto a conventional pot having a pouring edge. The cover includes an upper cover module and a lower cover module; the upper cover module is composed of a closed unit and a latching device and is closed by the lower cover module by an intermediate plate. The lower cover module includes an edge cover having a seal and a valve arrangement. It should be understood that an edge cover means a lower cover having a peripheral web or edge that includes a seal and can be embedded in the pan. The cover further includes a closure unit that is generally formed with a button and the cover is detachable from the pan by the closure unit. To create a pressure tight container, the lid can be latched onto the cooking pot.

According to the present invention, the closure unit includes a member to be removed from the edge cover together with at least a portion of a latching device. Therefore, the cover includes two modules, that is, a lower cover module having an edge cover and a valve arrangement, and an upper cover module having a closed unit, a latching device and an intermediate plate. Since the member is disposed on the closure unit itself to separate the unit from the edge cover together with the latching device, the upper cover module can be separated from the lower cover module in a very simple manner and, for example, without the need for the lower cover module Group remove the nut or screw.

The edge cover includes a member on which the closure unit can be secured. After the closure unit and the latching device and the intermediate plate have been removed, in other words, after the upper cover module has been removed, the latch can be eliminated One of the organization's conventional fixture configurations replaces this module section. Thus, the edge cover, together with the additional clamp, produces a common cover that is well suited for conventional decompression or low pressure cooking. Because of this simple interchangeability, the user does not need to have two different usable covers, namely one for pressure cooking and one for decompression or low pressure cooking.

The cleaning of the cover is also facilitated because the mechanism for removing the closure unit and the latching device is disposed in the upper cover module on the upper surface of the cover. For example, the alignment of one of the screws on the bottom side of the lid generally interferes with the cleaning procedure because food debris can foul the bottom side after the cooking process.

In one development of the present invention, the closure unit can be secured to a valve that is preferably centrally attached to the edge cover. In this advantageous embodiment of the present invention, a valve housing, for example in the form of a hollow cylinder, can be used to secure a closure unit thereto. Therefore, the closing unit does not have to be fixed by a special bolt or the like, and when the edge cover is used as a common cover for decompression or low-pressure cooking, the valve fixed to the edge cover does not interfere, but is formed as another One of the fixture configurations.

Thus, as set forth in a preferred embodiment of the present invention, at least one valve is disposed in the edge cover, the valve hollow cylinder of the valve being used to secure the closure unit or a clamp arrangement. This valve is used in one embodiment of the present invention to fix the working pressure of the pan. This means that the valve disposed in the edge cover is opened at the desired working pressure, and therefore the temperature in the pot is mainly adjusted to be higher than the boiling point of water.

However, in an alternative embodiment of the present invention, a safety valve may or alternatively be integrated into the edge cover in place of a valve for securing the working pressure, the safety valve acting as a second valve that fails in the other valve The condition opens at a higher pressure and/or it locks the latch of the cover at a pressure that prevents another valve from being manually opened.

In an advantageous development of the present invention, the valve system is adjustable. For example, this can be done in a simple manner because the bias of a valve spring can be adjusted by a set screw. The user can fix different pressure levels for cooking at different temperatures by means of this adjustable valve.

In a preferred embodiment of the present invention, the upper cover module is separated from the lower cover module via a slider mechanism. The slider mechanism includes a slider that is coupled in a position to a collar that secures a bolt, such as a hollow cylindrical valve housing. The slider is displaced into a position by displacement of one of the sliders in which the positive connection is released. Therefore, the upper cover module can be removed from the lower cover module and the upper cover module can be separated from the lower cover module in a very simple manner by pressing on the clamp of the slider.

In a preferred embodiment of the present invention, the latching means can be actuated by a button of the closure unit to separate the cover from the pressure cooker. In particular, the fixed claw having the U-shaped end is used as a latching device and is engaged in the pouring edge of a pot, and when the button of the closing unit is rotated, the fixed claws are guided at least inwardly (in other words, along One of the directions of the central axis of the pot moves radially. The direction of movement of the jaws preferably extends upwardly while in the direction of the button of the closed unit. Therefore, in the latched state, if the pressure is accumulated, an inward guiding force is applied to the claws. Therefore, only one of the available forces can be unlocked or unlocked, especially at a relatively high pressure.

This can further improve the safety of the pot in combination with a safety valve that locks the latching device. The pan preferably includes two valves, i.e., a valve for securing the working pressure and a safety valve that latches the latching device such that the pan cannot be opened when pressurized. The safety valve may also be designed in such a way that the safety valve is actuated by one of the higher pressures than the other valve under the condition that the other valve fails.

In a preferred embodiment of the present invention, the latching means of the cover is locked by at least one of the valves in a pressurized state. To this end, for example, a pin of a safety valve engages in a corresponding recess in the closure unit, so that when the pan is pressurized, the pin prevents rotation of the button of the closure unit, with which the latching means of the cover are actuated.

At least one of the valves can also actuate a pin attached to the removable portion of the cover (specifically, attached to the closure unit). For example, the pin can be used to transmit the pressure provided in the pan to the user as a visual signal.

In one embodiment of the present invention, the cover includes an intermediate plate disposed as a portion of the upper cover module between the closure unit and the edge cover and having a notch in a peripheral web at the edge, the notches A first mounting and guiding point for attaching the web to the fixed jaw to latch the cover is formed. The removable upper cover module is formed with a latching device and a closing unit above the intermediate plate. In particular, the intermediate plate is used to attach a latching device. The intermediate plate is preferably coupled to the edge cover so as not to be axially rotatable when the upper cover module is assembled, and the closure unit is rotatably secured to the intermediate plate such that the locking jaws for locking the cover are closed by the button of the closure unit Actuating in a manner that one of the drivers on the end of the connecting web opposite the jaws engages in a circular sector-shaped recess in the intermediate plate, and is mechanically coupled to the rotatable closed unit, from the closed unit One of the rotational movements exerts a longitudinal movement of one of the connecting webs in the radial direction.

In one development of the present invention, the intermediate plate can be removed from the lower cover module together with the closure unit and the latching device. A conduit is disposed between the intermediate plate of the upper cover module and the edge cover of the lower cover module, and steam or water vapor discharged through the at least one valve can escape through the conduit. This conduit can be particularly easily cleaned in the separated state of the upper cover module and the lower cover module. This is also particularly advantageous if the steam escapes only through the conduit between the intermediate plate and the edge cover and is not shunted along the mechanical components of the latching device. Thus, the food residue conveyed with steam or moisture can only contact the wall of the conduit, which wall is formed so that it can be easily cleaned and has no covering surface.

The cover preferably consists of two detachable cover modules, wherein the upper cover module comprises a closure unit having an interlocking button and a latching device for latching the cover to the pouring edge of a pot and covering the intermediate plate And the lower cover module includes an edge cover for covering the pot and a valve arrangement.

The present work is further directed to a pressure cooker cover (specifically, having one or more of the features described above) including an edge cover having a seal and at least one valve.

According to the present invention, a latching device is disposed on an intermediate plate, and the intermediate plate is then disposed on Between the edge cover and the enclosed unit and part of the upper cover module. The intermediate plate can be removed from the edge cover together with the closure unit and the latching device, wherein a conduit is formed between the intermediate plate and the edge cover, and steam discharged from the at least one valve can be released to the outside through the conduit. Since a conduit disposed between an intermediate plate and an edge cover is used, it is possible to largely prevent steam or moisture from coming into contact with the mechanical structure of the latch device and to prevent particulate contamination in steam and moisture from being relatively difficult to clean. Latch mechanism.

The present invention is further directed to a pressure cooker cover that includes an edge cover having a seal and at least one valve for securing a working pressure. In addition, a safety valve belongs to the edge cover. According to the present invention, at least one of the hollow cylindrical valve housings of the valves (specifically, if attached to the edge cover) is modified to serve as a base, the closed unit of the cover upper cover module is via a positive The assembly is releasably secured to the base.

The present invention will be explained in more detail hereinafter with reference to the drawings in which Fig. 1 is a schematic sectional view of one of the pressure cookers in which the cover has been assembled; Fig. 2 shows a detail of the sectional view shown in Fig. 1; Fig. 3 a perspective view of a pressure cooker cover; FIG. 4 is a perspective view of a cover module; FIG. 5 is a perspective view of a cover module; FIG. 6 and FIG. 7 show details of a closed unit of the upper cover module; 8 is a perspective view of the cover cut along a plane on a central axis of a cover; FIG. 9 is another cross-sectional view of one of the covers; FIG. 10 shows details of one of the upper cover modules; and FIG. And Figure 12 shows the latch mechanism of the upper cover module.

1 shows a schematic cross-sectional view of one of the pressure cookers 1 according to one embodiment of the present creation. The pressure cooker comprises a pot 3 having a pouring edge 4 and a lid 2. The pressure cooker is formed as a pressure vessel. A latching mechanism can be actuated via the closure unit 6 with which the lid is latched onto the casting edge of the pan. The pot is sealed by a lip seal 5. The cover includes a valve 7 for securing the working pressure and a safety valve 8.

Figure 2 shows a detailed view of one of the covers depicted in Figure 1, which can be better seen in Figure 2, in particular, the valve configuration. The cover 2 includes an edge cover 9 that is fitted to the pan and has a seal (5 in Fig. 1). A first valve 7 is attached to the edge cover, via which the working pressure of the pressure cooker is fixed. The valve (in this case, only the valve housing) is centrally secured to the edge cover 9 by a nut 10. The edge cover and valve arrangement are part of the lower cover module.

Furthermore, a closed unit 6 belongs to the cover and is rotatably attached to the outer casing of the valve. To this end, the outer casing of the valve comprises a peripheral recess 12, wherein the closed unit can be fixed by means of a slider 11. To this end, a conduit 26 (not shown) is preferably provided, with which the slider is pressed outwardly. By pressing on the slider, the slider is displaceable against a spring force into a position in which the positive connection in the groove in the outer casing of the valve is released. The closure unit is further rotatably coupled to an intermediate plate 15. By rotating the closure unit, the lid can be latched via the jaws, as described in more detail below with reference to the other figures. The closed unit and the intermediate plate are part of an upper cover module.

The edge cover 9 also includes an additional valve that is eccentrically configured and formed as a safety valve 8 in this embodiment. The safety valve is also fixed to the edge cover. The safety valve is formed as a ball valve having a ball 18 that abuts against a sealing surface by a spring. A seal ring 17 acts as a seal for the valve housing. It will be appreciated that additional sealing members associated with valve 7 may also be provided. The upper portion of the safety valve includes an upper portion 13 by which one of the cooking pins disposed in the closing unit 6 is actuated 14. Using the cooking pin, it can be determined whether the pan is pressurized. The upper portion that engages in one of the recesses in the closure unit 6 when pressed prevents the closure unit from being rotated when the pan is pressurized, and thus prevents the latch mechanism from being actuated. Further, pressure can be released from the pressure cooker by pressing down on the cooking pin to then open the pressure cooker.

Both the valve housing of the valve 7 and the valve housing of the safety valve 8 have a transverse conduit 19 through which steam can escape into a conduit 16 formed between the edge cover 9 and the intermediate plate 15. Since the intermediate plate can be removed together with the closure unit 6, the catheter is particularly easy to clean. In particular, due to this configuration, steam and moisture do not leak at the claws of the latch mechanism.

Figure 3 shows a perspective view of a cover. An edge cover 9 enclosed by three U-shaped fixed jaws 20 can be seen. The fixed jaws are coupled to the closure unit 6 via a connecting web 22. The closure unit has a button 21 via which the entire cover can be removed. To actuate the latch mechanism, the closure unit can be rotated via the button. The fixed jaws are movable inwardly when the latch pot and the clamp below the pouring edge of the pot. In order to remove the cover unit including the closed unit and the latch mechanism, the slider 11 can be pressed, and a part of the module including one of the latch mechanisms can be removed.

The assembly of the upper cover module is illustrated in a perspective view of FIG. The three fixed jaws 20 coupled to the closure unit 6 via the connecting web 22 are visible. In the illustration, the closed unit is closed downward by the intermediate plate 15.

After the upper cover module has been removed, the lower cover module remains with the edge cover 9, which, as illustrated in the perspective view of FIG. 5, includes a peripheral seal 5. Furthermore, a valve 7 is attached to the edge cover, the valve housing of which includes a recess 12 for securing one of the upper edges of the closure unit 6. In this view, the conduit 19 is clearly visible, which is disposed on the outer casing of the valve and through which steam can escape. A safety valve 8 is also disposed on the edge cover and also includes a conduit 32 through which pressure can be released; the two conduits are formed in the conduit 16 formed between the intermediate plate 15 and the edge cover Widening. The lower cover module can now have a new cover (not shown) that does not include a latching mechanism and can therefore be used as one of the covers for decompression or low pressure cooking. This cover preferably covers both the valve and the safety valve. Since the upper valve cylinder is used as one of the bases of the closed unit and due to the fact that the safety valve is disposed in direct proximity, the two valves can be covered with a cover. Thus, the lid 2 is visually distinct from one of the conventional lids for reduced or low pressure cooking; a second or additional lid does not necessarily remain available for reduced pressure cooking.

Figure 6 shows a perspective view of a closure unit 6 of the upper cover module, the upper cover module including a slider 11 for removing the closure unit (and a latching mechanism (not shown)). The slider and a pin 23 are displaceably mounted in the button 21 of the closure unit. In addition, the button contains an extension for receiving a hole in the upper portion 13 of the safety valve 8 and outwardly as a cooking pin 14.

FIG. 7 shows a perspective view of the slider 11. The slider includes a recess 1 24 of a larger diameter and one of the smaller diameters intersecting the recess 1 and an additional recess 225. In other words, in the basic state, if the slider is not laterally pressed via its clamp, the recess 2 is located below the set of rings disposed on the valve housing of the valve 7, and thus ensures a releasable positive connection. When the slider is laterally pressed, it moves from its rest position to a position in which the larger diameter notch 1 coincides with the axial direction of the collar of the corresponding valve cylinder. Therefore, the positive connection is released and the closed unit 6 can be removed. The pin 23 prevents the slider from being pushed out of its housing by a spring (not shown) provided in the conduit 26, which pin is formed by the button 21 of the closure unit.

Figure 8 shows a perspective view of a cover 2 including a cover module that is cut along an axially extending plane. The U-shaped fixing claws 20 which can be clamped under the pouring edge 4 of a pot 3 (not shown) can be clearly seen. The pot is sealed to the lid via a lip seal 5.

9 shows a cross-sectional view of the upper cover module, which basically includes a closure unit 6, an intermediate plate 15, and a fixed jaw 20. The intermediate plate is configured to fix the closed unit and the claws, and is in an assembled state The intermediate plate forms a mechanical interface between the upper cover module and the edge cover 9 of the lower cover module.

Further details will be explained with reference to Figure 10, which shows a perspective view of the intermediate plate 15 as part of the upper cover module from below, with the corresponding surface facing the edge cover 9. The intermediate plate includes a central recess 327 that slides over the valve (7 of Figure 5) centrally disposed on the edge cover in the assembled state. Furthermore, the intermediate plate comprises an additional recess 4 28 which slides over the safety valve (8 in Fig. 5) in the assembled state. Since the hollow cylindrical outer casing of the safety valve is located in the eccentrically disposed recess 44, the intermediate plate cannot be axially rotated relative to the edge cover in the assembled state. The intermediate plate 15 further includes a conduit 16 in which steam and moisture escape through the conduit between the intermediate plate and the edge cover. It should be appreciated that the conduit 16 can include an edge seal, which is not shown in greater detail in this embodiment. For example, a sealing gap 36 can be formed at the edge to attach a seal. Again, the gap 36 is formed as a dual forming boundary that can define the conduit 16.

Figure 11 shows further details of the intermediate plate 15 and the latching mechanism as part of the upper cover module. The intermediate plate includes one of the edge webs 31 recessed in the region of the connecting web 22 to the jaws 20. As already described, in the assembled state, the intermediate plate is axially fixed by the recess 4 28 and via the valve cylinder of the safety valve 8. The connecting webs include a recess 5 33 that cooperates with the closure unit 6, as illustrated below. The intermediate plate includes circular segmented recesses 29 for guiding the connecting webs and the jaws.

Figure 12 shows a perspective view of the underside of the closure unit 6 of the upper cover module. Depending on the number of connecting webs 22, the pins 30 belong to the closed unit and, in the assembled state, engage in the recesses 5 33 in the connecting webs depicted in FIG. If the button 21 of the closure unit is now rotated relative to the intermediate plate 15, the pin 30 acts as a driver into the groove 29 and the pawl 20 can thus move radially outward or inward. The drives or pins are preferably mushroom shaped and can be used to secure the intermediate plate, the connecting web and the closure unit because of the larger diameter beneath the grooves. Notch 27 and disposed on the closed list One of the hollow cylindrical portions 34 may also form a hinge that holds the intermediate plate and the closure unit together. The closure unit further includes a recess 635 in which the upper portion 13 of the safety valve (8 in Fig. 5) is engageable with the cooking pin 14 and thus prevents the button of the closure unit from rotating when the pan is pressurized.

It is advantageous from the present invention to provide a pressure cooker having a simplified process.
