Definitions

  • the invention relates to a device for the heat treatment of food by means of steam or a steam-hot air mixture in a cooking space which can be closed by means of a door.
  • the object of the invention is to clean the cooking space and all parts that are subject to precipitation due to the heat transfer medium.
  • the cooking space should be understood to mean any area of the device in which precipitation can be deposited by the heat transfer medium steam or steam-hot air mixture.
  • the spraying or spraying device comprises a spray head in the manner of a hand shower and a flexible supply line which connects the spray head to a water connection.
  • the water connection for the spray device can be provided on the device outside the cooking space.
  • the arrangement is such that a branch connector is provided on the water supply line, which is necessary anyway, for the water consumers provided in the device, to which the flexible supply line, ie a flexible hose, is connected.
  • the flexible supply line ie a flexible hose
  • consumers can also use condensation devices for the vapors and cooling devices that are provided, which are provided to cool the device rapidly after a cooking process at high temperature so that a treatment process at low temperature can be connected.
  • this hose can be firmly connected to the water connection, and it is also possible to provide a detachable plug connection known per se, as is necessary if, in a further embodiment of the invention, the water connection for the spray device on the device inside the cooking space is provided and the spray device is releasably connectable to the water connection.
  • this configuration is more complex, it has the advantage that the risk of hosing down the entire device from the outside is substantially reduced, because the hose will only be so long that it is sufficient for spraying the cooking space. Because the food is treated with steam, it is imperative that all electrical devices, such as the heating, are steam-tight and thus watertight.
  • the device however, has ventilation slots on the outside through which water, for example, can reach electrical or electronic control devices when the device is sprayed from the outside, which, because they are not connected to the interior, are also not vapor and water-tight encapsulated .
  • a building-fixed connection provided in the immediate vicinity of the cooking device can also serve as the water connection.
  • the spraying device is provided with an admixing device for admixing a cleaning agent with the spray water.
  • the cleaning agent is applied in the same simple, convenient and quick manner as the subsequent spraying out of the cooking space.
  • the admixing device can include a receptacle for a cleaning agent within the spray head, which can be carried along by the water flow.
  • Models can be used here, such as those known for car wash brushes with a shampooing device or for garden spray systems with an admixing device for insecticides or fertilizers.
  • the admixing device can also be constructed in the manner of a water jet pump, in which the water jet entrains cleaning agents from a connected container due to its flow energy.
  • the spray head can have a manually operated shut-off valve which can be operated by means of a push button or lever.
  • shut-off valves are known in the known hand showers on kitchen sink sinks.
  • a shut-off valve is provided in the feed line of the spray device, which in its open position provides the power supply for the electrical operated parts of the device interrupts.
  • a suspension device will be provided on the outside of the heat treatment device in order to be able to suspend the spraying device.
  • a roll-up device for the flexible feed line can be provided, which is expediently arranged behind a cladding.
  • a retractor can be mounted below the table top. The use of a retractor is not only limited to the installation of the spray device outside the cooking space.
  • such a retractor can also be provided behind a cladding in a wall niche of the cooking space, so that the detachable connection of the supply line to the water connection which is usually necessary in the interior arrangement can be dispensed with.
  • This detachable connection is only necessary if the supply line and the spray head cannot remain inside the cooking space.
  • the device for the heat treatment of food is a device which comprises a housing 1 which, in addition to the usual and not shown front paneling and door, has a partition 2 which divides the housing into two closely separated spaces.
  • a pressure space 4 is separated from a cooking space 5 by a further partition 3, the pressure space 4 being connected to the cooking space via slots 6 and 7.
  • the bottom of the cooking space is designated 8 and opens into an outlet 9, from which grease, cleaning fluid etc. from the cooking space get into a sewage pipe, which is permanently installed on site.
  • a Fan 10 is provided, which is provided by a heater 11 for heating the circulating air, which is sucked in through an opening 12 in the partition 3 from the cooking chamber 5 and pressed into the cooking chamber after heating via the slots 6 and 7.
  • a motor 17 for the blower 10 and all the control elements, which are designated as a whole as 18 and for controlling the heater 11, a heater 19 of the steam generator 14, is accommodated in the space of the device, which is located at 16 on the right of the partition 2 and is designated 16 as well as other elements necessary for the operation of the device.
  • the motor 17 and the control elements 18 are therefore located on one side of the device, while the steam generator 14 is arranged on the rear of the device.
  • This steam generator is fed with fresh water via a feed line 20 which opens into the device from below.
  • the device shown is a table-top device which rests on a table top 22 by means of feet 21.
  • the feed line 20 is provided with a branch connector, which serves as a water connection 23 for a spraying or spraying device, designated overall by 24.
  • This spray device 24 comprises a flexible hose 25 which is connected to the water connection 23 and a spray head 26 which is designed in the manner of a hand shower.
  • the spray head 25 is provided with an actuating lever 27, which is an existing valve in the spray head 25 operated, which allows water to escape from the spray head via spray nozzles 28.
  • the flexible hose is so long that it allows the spray head 26 to be inserted into the cooking space for spraying the same.
  • FIG. 2 shows a variant of the spraying device.
  • the flexible hose 25 is wound on a roller 31 which is spring-loaded in the direction of rotation and which is held by means of a holder 32 on the underside of the table top 22.
  • the roller 31 is connected to the water connection 23 via a coupling piece 33, which allows the roller 31 to rotate.
  • the end of the flexible hose 25 facing away from the spray head 26 is connected to an angular connecting piece 34 which is connected to the inside of the roller 31, so that there is a connection to the water connection 23 via the roller 31.
  • the spray head 26 is in a recess 29 of the table top 22, while the flexible hose is wound on the roller 31.
  • the water connection 23 is connected to a socket 35 arranged in the interior of the cooking space 5, into which the flexible hose 25 can be inserted if necessary by means of a plug 36 arranged at its end facing away from the spray head 26.
  • the socket has a valve inside, which can be actuated by a handle 37 arranged on the outside of the device in order to open the water connection when the flexible hose 25 is plugged into the socket 35.
  • FIG. 4 shows a further modification of the spraying device.
  • This modification includes a solenoid valve 38 which is connected to the water connection 23.
  • the solenoid valve 38 is connected to the control 18 via a line 39 and switches off the power supply to the device when it is opened via a line connected to the hand lever 27 and embedded in the flexible hose.
