Definitions

  • the invention relates to a cooking appliance with a system with a liquid container for the cooking appliance according to the preamble of patent claim 1.
  • a household appliance with a control panel and with a liquid container designed as a tank for receiving a fluid is known.
  • the tank In the operating position of the household appliance, the tank is arranged behind the control panel in the interior of the household appliance, the control panel being movable back and forth between a rest position without access to the tank and an exposed position with access to the tank.
  • the tank has a connecting channel designed as an outlet valve, with the liquid container having a combined filling/emptying opening for filling and/or emptying the liquid container and a connection opening arranged below the filling/emptying opening for flow-conducting connection to the cooking appliance designed as a household appliance and on the other hand, the connecting channel has a connecting piece for the flow-conducting connection of the connecting channel with the connection opening and a dip connecting piece with a dip connecting-piece opening arranged below the connecting opening for the flow-conducting connection of the connecting channel with the liquid container.
  • the invention therefore addresses the problem of improving a cooking appliance with a system having a liquid container for the cooking appliance.
  • a cooking appliance with the features of patent claim 1, which is characterized in that the connecting channel additionally has a return opening arranged above the immersion nozzle opening for the flow-conducting connection of the connecting channel to the liquid container, the connecting channel being designed in such a way that an in the liquid rising from the dip fitting flows back through the return opening into the liquid container until the return opening is closed by liquid in the liquid container.
  • the advantage that can be achieved with the invention is, in particular, that a system with a liquid container for a cooking appliance, a connecting channel and a cooking appliance are improved. Due to the inventive design of the system with a liquid container for a cooking appliance, the connecting channel for a system and the cooking appliance, it is possible, for example, to move the liquid container filled with a liquid more easily by means of the connecting channel from the cooking appliance to a drain for emptying the liquid stored in the liquid container To wear, for example, a condensate, without there being a risk that the liquid in an undesired manner from the connection opening of the liquid container out and runs down on or in the cooking appliance or drips onto a floor of a kitchen or the like.
  • the system according to the invention can be freely selected in terms of type, mode of operation, material and dimensioning within wide, suitable limits. See, for example, the above statements, in which the system is used on the one hand for collecting and disposing of condensate from the cooking appliance and on the other hand for supplying the cooking chamber of the cooking appliance with water or the like. It is also conceivable that the system according to the invention can be used both for supplying the cooking appliance with liquid and for disposing of liquid from the cooking appliance. As already stated, the liquid can be water or any other suitable liquid. Purely as an example, only cleaning fluids or the like are referred to here.
  • the system additionally has a fill level monitor for monitoring a maximum fill level in the liquid container in the connection position of the liquid container, the maximum fill level being arranged between the return flow opening and the dip nozzle opening. In this way it is possible to automatically monitor the maximum filling level in the liquid container for the proper functioning of the system. If the maximum fill level is exceeded, suitable actions can be triggered, for example an acoustic and/or visual warning to a user of the cooking appliance or the liquid being automatically pumped out of the liquid container.
  • a further advantageous development of the system according to the invention provides that the filling/emptying opening is arranged on an upper side of the liquid container, preferably that the filling/emptying opening extends over a large part of the upper side of the liquid container, particularly preferably that the filling/emptying Drainage opening can be covered by a lid of the liquid container or is arranged in a lid of the liquid container. This enables easy handling of the liquid container when it is being filled with liquid or when it is being emptied. This applies in particular to the preferred and in particular to the particularly preferred embodiment of this development.
  • the connecting channel is designed as a separate component that can be connected to the liquid container, the connecting channel being fixed in a flow-conducting manner in a mounting position of the connecting channel at the connection opening of the liquid container.
  • the production of the connection channel is made possible independently of the production of the liquid container. Accordingly, there is greater design freedom in the production of the liquid container and the connecting channel.
  • the liquid container on the one hand and the connecting channel on the other hand can be made of different materials, so that the choice of material can be better adapted to the functional requirements in each case.
  • connection channel when the system is transferred into its connection position, the connection channel can be connected to a device connection piece of the cooking appliance that protrudes through the connection opening into the liquid container in the connection position for the flow-conducting connection of the liquid container to the cooking appliance, preferably that the connecting channel has at least one circumferential sealing lip on the device socket side, particularly preferably that the sealing lip engages in a groove of the device socket designed to correspond to the sealing lip in the connection position of the system.
  • the at least one circumferential sealing lip also ensures that liquid adhering to the device connector when the system is transferred from its connection position to a non-connection position, i.e. to a position in which the system is no longer connected to the device connector in a flow-conducting manner, is not applied in an uncontrolled manner or runs down in the cooking appliance, but is stripped off by means of the sealing lip in such a way that the liquid can drain back into the liquid container.
  • the device connector it is also possible for the device connector to have a drip flange on an outlet opening of the device connector on the connecting channel side.
  • connection channel has at least one circumferential sealing lip on the connection piece side for sealing an appliance connection piece of the cooking appliance protruding through the connection opening into the liquid container in the connected position of the system.
  • connection channel is designed as a one-piece silicone part, preferably as a silicone elastomer part or silicone rubber part. Silicone is particularly advantageous for the function of the connection channel according to the invention. This applies in particular to the design of the connecting channel as a silicone elastomer part or as a silicone rubber part.
  • connection channel according to the invention provides that the connecting piece is designed for a positive connection, preferably for a locking connection, with an edge of the connection opening of the liquid container. In this way, the transfer of the connection channel according to the invention into its mounting position is made possible in a manner that is particularly simple in terms of design and production technology.
  • connection channel has a spacer rib on the connection piece side for holding the connection channel at a predetermined distance from a wall of the liquid container having the connection opening. This makes it possible in a simple manner to set a distance of the connecting duct from the wall on which the connection opening is formed, which is required for the proper functioning of the connecting duct, when transferring the connecting duct into its installation position.
