Definitions

  • This description relates to an electrical appliance for heating outdoor places such as terraces, balconies, etc.
  • This radiator offers an alternative to outdoor heaters running on propane / butane gas.
  • the movement and storage of the device are therefore significantly simplified and secure in the absence of risk of gas leakage.
  • This unit connects directly to the mains via a simple power socket. This eliminates the unpleasant gas failure and saves the user from having to change the heavy cylinder regularly.
  • the design of the device ensures that the entire electrical part of the device is protected from any splashing liquid.
  • the user is protected against splashing glass in case of bursting of the tube by interposition of a sheet also to contain any debris.
  • This double skin also allows air circulation to cool the active part of the device.
  • the active element for transforming electrical energy into heat is a tube using shortwave infrared technology. High-frequency thermal waves pass through the air without heating it and thus bring the heat precisely and economically where it is needed. It follows that this type of heating is insensitive to drafts. This technology is therefore particularly well suited for outdoor use. It heats only people and objects located in the radiation zone of the device.
  • the active element can also use other technologies that could give it different characteristics, adapted to other types of use.
  • the device can be used on different supports depending on the user's needs: stand-alone stand-up mounting, parasol-type mounting on a garden table and wall mounting.
  • stand-alone foot consisting of a solid base and a bent tube through which the power cable passes allows the user to install the device as it pleased provided that the ground is smooth and horizontal.
  • the wall mounting is recommended for places requiring regular heating and can not clutter the ground.
  • All these supports have a function for the orientation of the device. This function is intended to give the user the ability to change the radiation area without having to move the entire unit.
  • the innovative design of this device is based on the use of two opposing reflectors whose complex shapes allow a particularly homogeneous and comfortable distribution of the radiation inside the heating zone. This arrangement allows to hide the eyes heating part, thus providing a nice and elegant appearance to the device. This feature also eliminates the use of protective grid or glass.
  • the apparatus is equipped with a system for adjusting the heat diffusion mode by modifying the geometry of the main reflector.
  • the device is equipped with a handle whose shape is integrated in the general design.
  • the frame of the apparatus consists of a frame connecting two parts on which are grafted the two reflectors and the module containing the heating element.
  • This module is quickly removable from the rest of the device thus facilitating the replacement of it.
  • the whole is covered with a body giving all the rigidity.
  • This very simple architecture provides the device with first-class reliability and significantly reduces the cost and maintenance time.
  • the components of the device are made of materials that can best withstand the effects of climate.
  • the invention relates to an electric heating apparatus.
  • the invention aims to improve a heating quality.
  • the invention relates to the field of heaters used outdoors and indoors.
  • the halogenated radiant element is an infrared source and is connected to a power source.
  • the radiant element is intended to emit energy that can be reflected on and by the first reflecting member.
  • the radiant element is also capable of heating an area to be heated directly and indirectly via the reflecting member.
  • the zone to be heated is a surface of the ground receiving the radiations of the apparatus.
  • the problem is that the radiant element is dazzling for the user.
  • the user is obliged to stand back to the device, which is not always easy to do when you are on a terrace of coffee and there are several consumers installed.
  • the reflecting surface receives not only the radiation coming directly from the radiant element but also the radiation coming from the reflection shell.
  • the invention therefore relates to an apparatus. electric heater according to claim 1.
  • the invention aims to allow a user to set a heating intensity according to the different uses of this device.
