Definitions

  • the present invention relates to a temperature conditioning device for a food transport container for conditioning air arranged in a container interior of a container body of the food transport container with respect to its temperature.
  • the known temperature conditioning devices are either permanently installed in the food transport container or removed only with great effort from the food transport container. This complicates maintenance of the temperature conditioning device and also leads to a complicated cleaning of the food transport container.
  • the present invention has for its object to provide a temperature conditioning device of the type mentioned, which is user-friendly and easy to maintain.
  • This object is achieved in that the temperature conditioning in a closed state of the food transport container from an outside of the container body in a wall of the container body of the food transport container can be used and removed from the same.
  • the temperature conditioning is used in a closed state of the food transport container in a wall of the container body and can be removed from the same, in particular when the Food transport container is filled with food to be transported, a simple replacement of, for example, defective, temperature conditioning device by a new temperature conditioning possible.
  • the arranged in the food transport container food must not be removed for this purpose. Furthermore, in the case of service, only the temperature conditioning device and not the entire food transport container must be returned for repair.
  • the temperature conditioning is used from an outside of the container body in a wall of the container body of the food transport container and can be removed from the same, a simple arrangement of the temperature conditioning is ensured at the food transport container. Furthermore, this makes possible a visually appealing design of the food transport container with temperature conditioning device arranged thereon.
  • a fluid connection can be produced through which a fluid, in particular air or another fluid heat transfer medium, can pass from the temperature conditioning into the container interior.
  • the temperature conditioning device can be inserted into and removed from a ceiling wall of the container body of the food transport container.
  • the temperature conditioning device comprises a heating module.
  • the temperature conditioning device comprises a cooling module.
  • the temperature conditioning device comprises a fan for driving an air flow through the temperature conditioning device.
  • the air arranged in the food transport container can be guided by means of the temperature conditioning device in a recirculating air circuit.
  • the temperature conditioning device comprises an adjustment module by means of which, for example, a temperature to be achieved by means of the temperature conditioning device can be monitored and / or a temperature achieved by the temperature conditioning device can be monitored.
  • the temperature conditioning device in particular when it is provided that the operating module is arranged on a front side of the temperature conditioning device.
  • the front of the temperature conditioning device in this specification and the appended claims is that side of the temperature conditioning device which, in the mounted state of the temperature conditioning device, faces a user when loading the food transport container with food or when removing food from the food transport container.
  • the operating module in the assembled state of the temperature conditioning device and in the closed state of the food transport container is accessible from the outside.
  • a temperature to be achieved by means of the temperature conditioning device can also be set in the closed state of the food transport container.
  • monitoring of the temperature achieved by means of the temperature conditioning device is then possible even in the closed state of the food transport container.
  • the temperature conditioning device preferably comprises a receptacle for a power supply line in order to store the energy supply line required for operating the temperature conditioning device in a particularly simple manner on the temperature conditioning device. This ensures that the power supply line is always carried and is not lost or forgotten.
  • the receptacle for the power supply line is designed as a take-up device for winding up the power supply line. In this way, the power supply line can be easily arranged on the temperature conditioning device.
  • the Temperature conditioning device comprises a connection for a power supply line, which is arranged on a rear side of the temperature conditioning device.
  • the power supply line then does not have to be routed around the container. This reduces a tensile load of the power supply line and thus a premature wear or defect.
  • the back side of the temperature conditioning device in this description and the appended claims is that side of the temperature conditioning device which, in the installed state of the temperature conditioning device, is arranged facing away from the food transport container during loading of the food transport container to a user or when removing food from the food transport container.

  • a side of the temperature conditioning device facing away from the container interior of the food transport container is substantially flush with an outer side of the container body of the food transport container.
  • the temperature conditioning device on the container body of the food transport container is releasably fixed.
  • a, in particular operable from the outside, locking device for releasably fixing the temperature conditioning device may be provided on the container body of the food transport container.
  • the container body comprises an air duct, in particular when the food transport container is equipped with food, to ensure a uniform distribution of conditioned by means of the temperature conditioning air to the food and thus a uniform conditioning of the food.

In this way, a particularly simple distribution of conditioned by means of the temperature conditioning air in the container interior of the container body of the food transport container is ensured.
  • the door comprises an air duct.
  • the air duct of the door comprises an air outlet, which is associated with an air inlet of the temperature conditioning device in the mounted state of the temperature conditioning device. That way is a particularly simple suction of the conditioned by the temperature conditioning device to be conditioned air from the container interior of the container body of the food transport container.
  • an air guide is arranged in each case in the door and in the container body of the food transport container.
  • a particularly advantageous intake of the air to be conditioned from the container interior of the container body of the food transport container and a particularly advantageous distribution of the conditioned air over all levels of the container interior of the container body of the food transport container, on which food to be transported can be arranged, guaranteed.
  • An advantageous distribution of the conditioned air results in particular when the air duct of the door and the air duct of the container body of the food transport container are arranged on opposite boundary walls of the container interior, so that the arranged in the container interior air at the door, in particular evenly over all insertion levels the food transport container is sucked in, is conditioned by means of the temperature conditioning device and is distributed over all insertion levels on a wall of the container body opposite the door, in particular via a specially designed air duct, preferably evenly.
  • the temperature conditioning device is designed as Um Kunststoffartmodul.
  • a small mass of the door of the food transport container and easy handling of the food transport container are ensured in particular when the temperature conditioning device and the door are arranged on mutually different walls of the container body of the food transport container.
