Definitions

  • the present invention relates to a rack for a cooking appliance, comprising a frame for holding at least one insertion column with a plurality of insertion levels.
  • Horden racks are known, for example, from US Pat. No. 4,757,184.
  • reference bodies are often arranged in the cooking appliance in order to be able to determine corresponding measured values of the cooking process via these reference bodies, which are then generalized and with the aid of which control of a cooking process is possible.
  • the measured values of such reference bodies can be determined via a sensor or a cooking process sensor.
  • the unpublished DE 103 09 485 is concerned with a method for controlling a cooking process, in which the total energy required for cooking or regenerating a food to be optimally adjusted.
  • the climate in the cooking chamber can be regulated in particular as a function of the temperature behavior of the reference body, preferably taking into account a determined before the cooking correlation to the temperature behavior of Gargutart, Gargutgut, Gargutelecommunications, Gargut bath and / or Garvor felicit a Garguts.
  • a sensor is placed in or on the reference body, which is in communication with a control and / or regulating unit of the cooking appliance. This sensor may be, for example, a cooking process sensor known from DE 199 450 21 A1.
  • cooking appliances that are used in commercial kitchens often include rack racks or oven rack carts on which food can be cooked or regenerated on a variety of shelves. It is obvious that corresponding measured values for controlling a cooking process can not be determined individually for each individual food to be cooked, which is arranged on a shelf level of the oven rack. Therefore, here a reference body within the cooking chamber of the cooking appliance can be advantageously arranged, can be determined with the measured values generally within the oven, and with which correlations with the food and the cooking process are possible. Since the measured values determined via the reference body should correspond as well as possible to the measured values actually exhibited by the cooking utensils arranged on the loading levels, the reference body should be arranged as close as possible to the cooking utensils.
  • the arrangement of the reference body within the oven must be user-friendly and safe.
  • an additional sensor or cooking process sensor is to be arranged together with the reference body within the cooking chamber in the vicinity of the food, the user-friendliness and in particular the cable length of such a sensor or cooking process sensor must be taken into account so that the cable does not touch food. An unwanted contamination of the food when arranging the reference body should be avoided.
  • sensor positioning devices are known from the prior art, which enable a sensor to be positioned, for example, with at least one rotational degree of freedom and at least one translational degree of freedom for introduction into food to be cooked, for example in catering containers between a plurality of rails of a hooking ladder, by a height adjustment and thus an assignment to a rail or a pair of rails of two opposite in height within a cooking space rails in addition to a rotation and displacement of the sensor relative to said rail or said pair of rails is possible, as described for example in the unpublished PCT / EP03-01491.
  • a positioning device is intended for positioning a reference body within a cooking appliance can be provided, which can be arranged user-friendly and safe in the immediate vicinity of the food to be cooked or to be regenerated, without causing contamination of the food by the reference body or related components, such as a cable.
  • a positioning device for positioning a reference body can be detected on the measured values of a cooking process, wherein the positioning device is attached via at least two webs on the tray rack, extending from a base frame or upper frame of the frame substantially vertically upwards or extend down.
  • the positioning device has a substantially horizontally extending between the webs, in particular beam or plate-like, section.
  • the positioning device is arranged approximately centrally of the height of the tray rack.
  • the positioning device has a recess, preferably centrally between the webs, for receiving the reference body.
  • the recess has a holding device for the reference body, such as clamps, sleeves, suspension devices, snap-in devices or the like.
  • the positioning device comprises a sleeve which extends from the recess and preferably has an opening which opens in particular into the recess.
  • the positioning device may be made of metal.
  • the reference body is a tube made of ceramic, clay, porcelain, Teflon or carbon fiber, or the reference body comprises a filled in the sleeve, in particular encapsulated, granules.
  • the reference body is substantially completely surrounded by the sleeve, whose opening extends laterally along the longitudinal direction.
  • the sleeve has an opening at its bottom.
  • the reference body is arranged angled with respect to the webs, preferably at an angle of about 45 ° C.
  • At least one sensor and / or a cooking process sensor is arranged in and / or on the reference body, wherein the sensor or cooking process sensor is in operative connection with a control and / or regulating unit of the cooking appliance.
  • At least one climatic parameter comprising a temperature value within the cooking appliance, a temperature increase, a moisture content, a moisture increase and / or the like can be detected via the sensor or the cooking process sensor.
  • the measured values of the reference body can be used to determine the dew point.
  • the present invention is based on the surprising finding that an optimal arrangement of a reference body can be achieved by the special arrangement of a positioning device on a tray frame according to the invention for a cooking appliance, which is user-friendly and safe. In particular, an unwanted contamination of the food, which is arranged on the insertion levels of the tray rack, avoided.
  • the reference body is arranged with the positioning device according to the invention in close proximity to the food.
  • this arrangement is not so far within the oven rack, that, for example, a cable to which a sensor or cooking process sensor is connected, would be too short and therefore would have to be pulled over or across the shelves, which undoubtedly leads to contamination of the food. Rather, according to the invention, the arrangement of the reference body in a simple manner on the tray rack possible and requires no excessive effort.
  • the reference body can preferably be easily inserted into a recess of the positioning device, wherein preferably a holding device, in particular in the form of a sleeve or terminals, may be provided to secure the reference body in the positioning device.
  • the reference body is a hollow ceramic tube which is surrounded by a metal sleeve belonging to the positioning device, which is laterally at least partially open in its longitudinal direction. A closed metal sleeve would falsify the measurement, since first the metal and then the ceramic tube would be heated.
  • the bottom of the metal sleeve is further provided with an opening, which is advantageous for the case when the ceramic tube is to remain permanently on the tray rack. With this opening, a cleaning in the cooking appliance by means of self-cleaning would be possible because appropriate cleaning fluid could flow easily from the bottom opening.
  • a sensor and / or a cooking process sensor is provided in and / or on the reference body.
  • this sensor or cooking process probe can be plugged into the cavity. If the sensor or cooking process sensor is in operative connection with a control and / or regulating unit of the cooking appliance, a cooking process can be controlled in a simple manner by recording measured values of the reference body.
  • the reference body may have a length of about 80 to about 120 mm, preferably about 100 mm, an outer diameter of about 10 to about 12 mm, preferably about 11 mm, and optionally an inner diameter of about 3 to about 5 mm, preferably about 4 mm, have.
  • the rack frame 1 shows an inventive rack frame 1, which has a frame 2 of a base frame 3, an upper frame 4 and connecting struts 5. Within the frame 2 six insertion columns 6 are integrated, which are fastened by means of bars 7 to the connecting struts 5 and thus to the frame 2. Each insertion column 6 has a plurality of insertion levels 8, which are defined by a ring shape for receiving a plate, not shown, or the like with food.
  • the rack frame 1 is a mobile oven rack. However, of course, a non-movable tray rack can be provided.
  • the base frame 3 has on its front side 9 and its rear side 10 each have a handle 11 which can be taken during the process of the oven rack 1.
  • two webs 12 extend substantially vertically upwards.
  • the webs 12 are arranged so that they extend substantially between two insertion columns 6, along the same.
  • the webs 12 not only extend perpendicularly away from the base frame 3, but they can also be first bent slightly from the base frame 3 in the tray rack 1 in order to then run even closer between the insertion columns 6. This leads to an even closer arrangement of a reference body on a food, as explained below.
  • the substantially vertical arrangement of the webs 12 shown in FIG. 1 is preferred.
  • the webs 12 may extend from the upper frame 4 substantially vertically downwards.
  • a positioning device 13 for a reference body 15 is arranged at approximately half the height of the tray rack 1 according to the invention.
  • This positioning device 13 comprises a substantially horizontally extending between the two webs 12 beams 18 and a recess 14, which is preferably arranged centrally in the beam 18.
  • the positioning device 13 comprises, as can be seen in particular Figure 2, also a unilaterally open sleeve 19, which surrounds a reference body 15, which may be embodied for example as a ceramic tube.
  • the corresponding opening 20 of the sleeve 19 in this case represents an extension of the recess 14 and allows, as well as the recess 14, a simple insertion of the reference body 15th
  • the reference body 15 is inserted by insertion into the opening 20 and the recess 14 in the sleeve 19, as is clear from Figure 2.
  • the reference body 15 is itself hollow or tubular, so that in the corresponding cavity of the reference body 15, a sensor 16 can be inserted, can be determined with the measured values of the reference body 15.
  • the reference body 15 is arranged very close to the insertion levels 8, which contain food to be cooked (not shown), but without allowing contamination of the food to be cooked.
  • the reference body 15 and the sensor 16 can be plugged into the positioning device 13 in a user-friendly and safe manner, wherein a cable 17 of the sensor 16 does not have to be pulled over or through the insertion levels 8.
  • the webs 12 furthermore serve as cable deflectors, since they prevent the cable from easily reaching the insertion levels 8.
  • FIG. 3 shows a cross section through the tray rack 1 according to FIG. 1.
  • the angled arrangement of the reference body 15 with respect to the webs 12 is particularly well shown here. preferably at an angle of about 45 ° C, which allows an even better approximation of the reference body 15 to the insertion levels 8.
