Definitions

  • the invention relates to a front cooking station with a food preparation area and with an air cleaning device.
  • the air cleaning device comprises: a duct system having at least one suction port for sucking air contaminated with vapor by the food preparation and at least one exhaust port of sucked air cleaned by the air cleaner into the surrounding area of the front cooking station, a fan containing the air from the at least one suction opening to the at least one exhaust air opening, at least one grease and / or odor filter arranged in the channel system, and a sensor arrangement having at least one pressure sensor related to the air flow direction, the pressure before the at least one grease and / or odor filter capture and report.
  • Such a front cooking station is for example off US 2014/020673 A1 known.
  • the object of the invention is to provide a safe front cooking station in the event of a fire.
  • FIG. 1 Another Front cooking station is for example from the US 5,133,786 A known.
  • the exhaust opening is provided in the bottom of an exhaust box, wherein the exhaust box is connected downstream of the blower.
  • the exhaust port is covered with a stack of multiple filter mats forming an odor filter.
  • a pressure sensor is provided within the exhaust box to detect the pressure in the exhaust box and to close at too high pressure on an overly added odor filter. Too much added odor filter is then signaled to the user by a corresponding warning light.
  • the object of the invention is to be able to recognize not only an over-added filter, but also a missing, defective and / or incorrectly installed filter.
  • the front cooking station has a control device for controlling at least the air cleaning device, that the control device closes on a missing, defective and / or incorrectly installed grease and / or odor filter when the pressure sensor delivers a value that is below a predetermined pressure threshold, and / or when a difference between the value supplied by the pressure sensor and another pressure value is less than a predetermined pressure difference threshold, and that the control means prohibits the operation of the at least one fan after being applied to one missing, defective and / or incorrectly installed grease and / or odor filter has closed.
  • the benefit of a possibly existing anyway pressure sensor can be significantly increased.
  • the monitoring of an odor filter arranged in an exhaust box is particularly appropriate because the pressures prevailing in such an exhaust box during trouble-free operation are known or easily detectable.
  • the sensor arrangement has at least one further pressure sensor which can detect and report the pressure behind the at least one fat and / or odor filter in relation to the air flow direction, the pressure difference being the pressure in front of and behind the at least one fat and / or odor filter is formed.
  • the pressure within an odor filter receiving exhaust box with the pressure in the vicinity of the front cooking station can be compared so that changes in ambient pressure can be considered, which is a particularly accurate monitoring option.
  • the sensor arrangement has at least one position sensor which can detect and report the correct installation position of the at least one fat and / or odor filter, wherein the control device prevents the operation of the at least one fan when the at least one Position sensor reports that the at least one grease and / or odor filter is not installed correctly.
  • the control device prevents the operation of the at least one fan when the at least one Position sensor reports that the at least one grease and / or odor filter is not installed correctly.
  • a wrong built-in grease filter can cause excessive fat in the channel system reflected, which is undesirable for both hygienic and fire safety reasons and what can be prevented by this measure.
  • the sensor arrangement has further position sensors which can detect and report the correct mounting positions of all parts of the front cooking station whose position must be changed to remove the at least one fat and / or odor filter , It can not be ruled out that, although the filter itself is correctly inserted, the incorrect (re) installation of other parts leads to the fact that proper operation of the front cooking station is still not possible.
  • the front cooking station has at least one inspection door and that the sensor arrangement has at least one closure sensor which can detect and report a correct closure of the at least one inspection door, wherein the control device controls the operation of the at least one Blower stops when the at least one closure sensor reports that the at least one inspection door is not closed correctly.
  • non-closed inspection doors can cause the intake air to escape from the front cooking station without having passed the odor filter. This state can be avoided if the control device permits operation of the at least one blower only if all the inspection doors are correctly closed.
  • the front cooking station has an extinguishing device with at least one extinguishing agent nozzle and with at least one temperature sensor for detecting overheating and / or a fire.
  • a fire can occur, for example, when the flames of food flames are sucked into a provided adjacent to the suction fat filter and set the very easily flammable fat deposits on fire.
  • the front cooking station has a first holder for an extinguishing agent tank and a piping system, which leads from the region in which the first holder is provided to the at least one extinguishing agent nozzle.
  • the front cooking station can be equipped with a self-sufficient extinguishing agent tank and it is not necessary to connect at the respective operating location of the mobile front-cooking station any extinguishing agent sources, as for example in the CN 102062430 A is proposed.
  • the first holder is provided in a region which is opposite both the food preparation area as well as against the channel system is protected by a flame arrester.
  • flame arresting in this context are less known from the classical explosion protection measures, but it is sufficient to provide the first holder and thus the extinguishing agent tank in a range which is sufficiently sealed off against potential fire sources, for example by flame retardant material such as sheets or similar.
  • the flame arrester is formed by a separate compartment.
  • a separate compartment here means any compartment which is not part of fire-prone sections of the front cooking station, because, for example, a compartment belonging to the channel system would be unsuitable for providing the first holder.
  • the separate compartment is a compartment closed in the operating state of the front cooking station.
  • a compartment formed from sheet metal walls constitutes a sufficient flame arrester.
  • the separate compartment is provided in an outer side area of the front cooking station. If the compartment is located in a side area of the front cooking station, a closed inspection opening of the compartment may form part of the side wall of the front cooking station, so that the compartment is readily accessible, for example, to exchange the extinguishing agent tank.
  • the compartment and thus the contained therein extinguishing agent tank in this arrangement has the maximum possible distance from potential fire sources.
  • the extinguishing agent nozzles it is preferred that at least one extinguishing agent nozzle is assigned to the food preparation area.
  • the spray angle of the extinguishing agent nozzle or the extinguishing agent nozzles is preferably selected so that the entire food preparation area is covered.
  • At least one extinguishing agent nozzle is assigned to the at least one fan. This solution is advantageous because ultimately each electric motor represents a potential source of fire, so that in one extremely unlikely, but not completely excluded case may occur that the fan catches fire due to overheating.
  • At least one extinguishing agent nozzle is assigned to the at least one grease filter. This measure is advantageous because it may occur, for example, in the case of short-term flame beers of food, that flames are sucked through the fat filters and ignite these or the fat deposited thereon.
  • at least one extinguishing agent nozzle is assigned to the at least one odor filter. This measure makes sense because, for example, a fan fire can lead to the odor filter, which is usually arranged behind the blower, being set on fire.
  • the at least one exhaust air opening is equipped with a closure device.
  • the closure device comprises a grid with lamellae, which can be brought into a closed position by a drive device.
  • the lamellae are preferably rotatably mounted about their longitudinal axis.
  • the actuation or rotation of the slats can then be effected by a drive device in the form of a cylinder, which is acted upon if necessary with a propellant gas.
  • the security is further increased by the fact that the extinguishing device automatically activates the closure device in the event of overheating and / or fire in order to close the at least one exhaust air opening.
  • the cylinder or cylinders of the drive device to be charged automatically with a propellant gas when the at least one temperature sensor detects overheating and / or a fire.
  • the extinguishing device comprises a manual actuating device with which the extinguishing device can be actuated independently of the fact that the at least one temperature sensor detects overheating and / or fire.
  • the extinguishing device can be operated, for example, even if the front cooking station is not yet connected to the mains, which will be necessary for the proper operation of the at least one temperature sensor, and still for some reason to a fire in the Front cooking station area comes, for example, because a vessel with burning fat on the front cooking station is turned off.
  • the front cooking station of the invention it is considered advantageous for the front cooking station of the invention to include a second holder for an extinguishing agent propellant tank.
  • the extinguishing agent and the propellant are stored in different tanks, it is for example possible to remove the usually smaller propellant tank with a longer transport of the front cooking station and to transport separately.
  • the extinguishing agent and the propellant in the form of, for example, propellant gas can be durable for different lengths of time or the tanks can be subject to different testing intervals, so that it is less expensive to renew only the agent currently being exchanged.
  • the control device is designed to report a missing, defective and / or incorrectly installed grease and / or odor filter (or another incorrectly installed element) to a service center.
  • the service center can be, for example, a data center of the distributor of the front cooking station or a cooperating organization that can be reached via the Internet.

  • the at least one exhaust air opening is equipped with a closure device, that it has an extinguishing device with an extinguishing agent tank and an extinguishing agent propellant tank, and that the closure device operated with propellant from the extinguishing agent propellant tank.
  • the closure device may comprise, for example, a suitable actuating cylinder, which exerts a piston when acted upon by the pressurized propellant.
  • the closure device in each case has a lattice with lamellae which can be rotated about their longitudinal axis
  • this piston can be articulated to the lamellae or to an element connected to the lamellae such that the lamellae are rotated as needed so that the exhaust air opening is closed.
  • this solution is particularly advantageous because it manages without electric drive elements, which could possibly no longer function in the event of a fire, and because the closure device is automatically triggered when the extinguishing device is triggered.
  • the conduit connecting the extinguishing agent propellant tank to the closure means is a metal conduit which can withstand fire for at least a sufficient time to ensure safe operation of the closure means.
  • the closure device by the use of spring elements in such a way that it releases the exhaust air opening again when the pressure decreases or has returned to normal level, another solution is presently preferred in this regard.
  • the exhaust port should, of course, after a small fire, which has caused no permanent or irreparable damage, of course, can be reopened to take the front cooking station, possibly after a repair back into operation. However, this should preferably be possible only manually, for example by optionally inserted lamellae are rotated about their longitudinal axis again.
