Definitions

  • the invention relates to a cooking appliance with filling opening for cleaning liquid, a system comprising a container for cleaning liquid and cooking appliance and a method for filling a cooking appliance with cleaning liquid.
  • Cooking appliances are in particular ovens, proofing cabinets and other devices suitable for bakery operations for storing and treating foodstuffs.
  • the refueling device comprises a wastewater tank mounted on a movable floor support, which is positioned in a sub-cabinet and easily moved.
  • detergent tanks are provided, which can be refilled via lines. As the filling of the detergent tank runs in detail, the pamphlets can not be found.
  • the invention has for its object to provide a cooking appliance with a filling opening for cleaning fluid, a system of a cooking appliance with a container for cleaning fluid and a method for filling a cooking appliance with cleaning fluid available that allow a clean and secure filling.
  • An inventive cooking appliance has at least one filling opening for filling cleaning liquid via a first line into the cooking appliance interior or into a tank.
  • the filling opening is designed such that at least part of a container is insertable into the filling opening, wherein within the filling at least one piercing element is arranged such that upon insertion of the at least one part of the container into the filling opening a closure element arranged on the container is pierceable in that the cleaning liquid present in the container flows into the cooking appliance interior or into the tank immediately after piercing.
  • closure element For the purposes of the invention, membranes, films and other pierceable elements are understood which on the one hand are suitable for tightly sealing a container and, on the other hand, of being severed by a piercing element arranged in a filling opening.
  • the dimensioning of the closure element may vary, in particular depending on the design of the piercing element and of the force normally applied during insertion of the container into the filling opening. This force, in turn, depends inter alia on the size and the resulting dead weight of the full container and the angle of the filling, in which the container is introduced.
  • cleaning liquids are understood to mean all cleaning liquids, including descaler, rinse aid and other liquids suitable for cleaning cooking appliances.
  • the cooking appliance according to the invention has the advantage that a container closed with a closure element with cleaning liquid can be introduced into the filling opening so that the cleaning liquid in the container exits only and only from the container when the piercing element has pierced the closure element.
  • the piercing element is preferably arranged so that escaping cleaning liquid runs exclusively through the filling opening into the cooking appliance. This ensures that no cleaning liquid is spilled before filling the cleaning liquid and in particular no cleaning liquid undesirably comes into direct contact with Be Pavllpersonal, food or with the food interior.
  • the piercing element has at least one element for detachable fastening in the region of the filling opening and / or at least one of the cooking device is in the region of the filling opening Element arranged for releasably securing the piercing element.
  • Suitable are all known non-positive and / or positive connection techniques, in particular a screw, a plug connection or a bayonet closure.
  • the above-mentioned connection form has the advantage that the piercing element can be easily removed from the filling opening for cleaning or replacement purposes and can be connected to it again. This ensures a long-term functionality.
  • a filter element is arranged in the region of the filling opening to ensure that no dirt particles or other solids pass through the filling opening into the cooking appliance interior or the tank of the cooking appliance.
  • the filter element is preferably arranged in the piercing element or below the piercing element. It may also be integrally formed on the piercing element.
  • the filling opening, the piercing element and / or the filter element are designed such that the filter element can be fixed in the filling opening with the aid of the piercing element.
  • a geometric design can be provided on the piercing element itself, which makes it possible to fit the filter element in this.
  • Such a geometric configuration may for example be a recess into which the complementarily formed filter element is inserted from above or from below or inserted from the side.
  • a geometric configuration can also be provided on the housing in order to fit the filter element as described above.
  • the filter element can also be positioned on a stop in the region of the filling opening in order to clamp it by means of the puncturing element arranged above it. This can be done for example by screwing the piercing element into the filling opening.
  • the piercing element is designed as an annular mandrel.
  • annular mandrel in the present invention, both those designs are called, in which the ring is closed, as well as those in which a plurality of piercing elements on a round, i. circular, oval or otherwise shaped, in particular arcuate, web are arranged, even if there is a free space between the individual piercing elements.
  • designs with polygonal geometry It is important that the mandrel is adapted to open the closure element over a large area, so that the cleaning liquid can flow out of the container quickly after piercing as possible without further action.
  • a closed ring e.g., a circular or polygonal ring
  • the membrane displaces outwardly from the mandrel as it pierces.
  • the mandrel is preferably designed in a further practical embodiment so that the closure element is torn, but not completely separated from the container.
  • the piercing element or the piercing elements have or have a distance of at least 1 mm from the inner boundary wall of the filling opening on their outer sides, enough space remains to be positioned around the wall of a container between the inner wall of the filling opening and the piercing elements for filling.
  • the distance is 1 mm to 10 mm, more preferably 2 mm to 5 mm.
  • the filling opening has at least one compensating opening leading through the piercing element.
  • This may be, for example, one or more compensation openings arranged in the peripheral wall of the piercing element, which - possibly via one or more channels - lead to a second line (bypass).
  • a compensating opening With such a compensating opening, the risk can be reduced that, in the case of a container positioned on a push-through element, such a high pressure forms in the short term that forms a return flow of cleaning fluid and thus could squirt cleaning liquid from the filling or dripping. Compensation openings therefore favor a fast, continuous and safe inflow of cleaning fluid.
  • the piercing element can be produced in a particularly inexpensive and simple one-piece manner. Suitable materials are not only plastics, but in particular also metallic materials, since these are particularly temperature resistant and can be cleaned very good germicidal by exposure to high temperatures.
  • the piercing element has a sharp-edged design on the side facing the outside of the cooking appliance, in order to minimize the force required for the piercing process.
  • the diameter of the filling opening is smaller than the width of a hand and sharp-edged elements are arranged so far away from the outer edge of the filling that they are not accessible by hand from the outside.
  • a dimension smaller than 5 cm (preferably smaller than 3 cm) and the distance to the outer edge of the filling opening greater than 5 cm (preferably greater than 10 cm) can be selected as the diameter of the filling opening.
  • the level of the tank is monitored by a sensor.
  • This sensor ensures that always at least one Nach Schoich manufactorevolumen can be filled, for example by a display, LED, via a control of a flap etc.
  • a sensor ensures that always at least one Nach Schoich micervolumen can be filled, for example by a display, LED, via a control of a flap etc.
  • it can be ensured that - in compliance with the instructions of the display, LED, etc. - the tank is not crowded or a not completely emptied container must be removed again from the filling opening.
  • the invention also relates to a system comprising a cooking appliance and a container, according to which the container in the region of the closure element is adapted to the geometry of the filling opening of the cooking appliance such that the internal dimensions (eg the diameter or the length and the width) deviate from not more than 20 percent, preferably not more than 15 percent and more preferably not more than 10 percent, of the external dimensions of the piercing element, so that the container is guided during the piercing of the closure element and during filling of the piercing element.
  • the container can simply be pushed so far into the filling opening until the closure element is pierced. Then, the container is positioned due to the geometric configuration of the piercing element. It can then be released, for example, to perform other activities. After emptying the container, it can be easily removed from the piercing element and recycled.
  • the tank of a cooking appliance according to the invention is provided with a venting device.
  • the filling opening 18 leads via a first line 20 to a tank 22 arranged in the region of the bottom.
  • a hose 20 is fastened to the pipe opening of the filling opening 18 and the tank 22 by means of hose clamps ,
  • a second line 24 with a significantly smaller diameter also leads from the filling opening 18 to the tank 22.
  • the function of the second line 24 will be explained in more detail below.
  • a further line 25 (here: also a hose) is arranged, which leads for venting from the tank vertically upwards. It has at its upper end at least one opening, which allows an air inlet and outlet at any time. It is further dimensioned so that leakage of the liquid from the tank in a conventional moving or moving or transport of the system is very unlikely or impossible.
  • the length of the further line 25 is greater than 50 cm.
  • the further line 25 can therefore be considered as a venting device.
  • the filling opening 18 is essentially formed by a base element 26 (FIG. Figure 3 ), which has a portion 28 of annular cross-section and a second portion 30 of annular cross-section, wherein the first portion 28 has a larger outer diameter than the second portion 30.
  • a base element 26 FIG. Figure 3
  • the base member 26 may have a different geometry inside and outside.
  • the inner portion of the first portion 28 serves to receive the in FIG. 4 shown piercing member 32 and the inclusion of a container, not shown in this figure, in particular a bottle or canister neck.
  • the outer portion of the second portion 30 serves - as in FIG. 8 shown - as a connection portion for the first line 20th
  • Piercing element 32 shown in detail consists of a first section 34 with an annular cross section and a second section 36 with an annular cross section.
  • the second portion 36 of the piercing member 32 has a larger outer diameter.
  • an external thread 38 is formed on the second portion 36.
  • the piercing element 32 is screwed into the base member 26.
  • the corresponding internal thread in the base element 26 begins at the in FIG. 7 to be recognized paragraph 40 within the filling opening 18.
  • a non-illustrated filter element is disposed between the piercing element 32 and the base member 26, for example by such a filter element is clamped by screwing the piercing element 32 into the base member 26.
  • two recesses 54 are formed in the transition region from the first portion 34 of the piercing member 32 to the second portion 36 of the piercing member 32.
  • the first portion 34 of the piercing element 32 has, immediately adjacent to the transition region to the second portion 36 distributed over the circumference a plurality of equalization openings 42 in the peripheral wall.
  • These equalization openings 42 serve, on the one hand, to create a possibility for pressure equalization in the case of a strong increase in pressure of the cleaning agent in the container, not shown, and in the first line 20. This possibility will be discussed in detail below.
  • FIGS. 5 and 6 show the base member 26 with screwed-through piercing element 32.
  • the four openings 44 with internal thread in the region of the front end serve to screw the base member 26 to the front housing 12 of the oven 10th
  • This distance d is dimensioned so that a container, in particular the neck of a bottle like the one in FIG. 9 shown bottle 48, between the piercing member 32 and the inner wall of the filling opening 18 dips.
  • the inner diameter of the bottle neck is equal to or slightly larger than the outer diameter of the piercing member 32, so that the bottle can slide easily on the piercing member 32 and is fixed in the pushed state in this position.
  • the end face is formed as an annular mandrel 52. It is in the present case a closed ring whose outer side is formed sharp-edged by an acute angle is formed by formed between the outer periphery and the inner circumference of the ring connecting surface and the outer circumferential surface of the first portion 34 of the piercing element. This angle is preferably less than 45 °, particularly preferably less than 30 ° and more preferably less than 20 °.
  • a bottle 48 is used whose opening in the region of the neck of the bottle is closed by a pierceable closure element (not shown).
  • the bottle 48 is first introduced into the filling opening 18 until the closure element abuts the annular mandrel 52.
  • the bottle 48 is then - possibly with increased application of force - moved towards the filling, so that the annular mandrel 52 pierces the closure element.
  • the closure element works over a large area to the side and makes it possible to flow the cleaning liquid in the bottle through the from the inner peripheral wall of the piercing element 32 in the direction of the first line 20.
