Definitions

  • the present invention relates to a heater comprising means for improve the flow of hot air.
  • Some current heaters built-in or not, in particular inserts or cassettes, are powered by different types of solid, liquid or gaseous fuels. They include a first envelope which contains a heating element and different means ensuring efficient combustion according to the fuel for which the device was designed. It is also known to add a second envelope around the first envelope, in order to recover the heat and convey it to the room to be heated by convection natural or forced air using one or more fans.
  • the heater built into a wall or fireplace, it also has a frame, fixed on the front part of the double envelope, in order to facilitate and hide the connection with the load-bearing structure (wall or fireplace).
  • incorporation into devices for heating a free space between the two envelopes can cause disturbances between the air flow ambient vacuumed from the room or from outside the room and the hot air flow to the room to heat.
  • the air flows are not always derived in the most efficient way for ensure a feeling of well-being for the consumer who is in the room to be heated.
  • the present invention relates to a new heater for modifying air flows hot and cold air circulating in said apparatus heating and which responds advantageously to the problem mentioned above.
  • the present invention relates to an apparatus for heating intended to be embedded or not in a structure load-bearing such as a wall or a room fireplace heat, and which has a first envelope incorporating a heating body made of materials suitable well known to those skilled in the art, such as steel, cast iron, refractory brick or any other material and incorporating different means of combustion suitable for solid, liquid or gaseous fuel used, and a second envelope completely surrounding or partially the first envelope intended to recover the heat and route it to the room to be heated by natural or forced convection using one or more several suitable means (such as fans, deflectors or baffles).
  • a structure load-bearing such as a wall or a room fireplace heat
  • a first envelope incorporating a heating body made of materials suitable well known to those skilled in the art, such as steel, cast iron, refractory brick or any other material and incorporating different means of combustion suitable for solid, liquid or gaseous fuel used
  • a second envelope completely surrounding or partially the first envelope intended to recover the heat and route it to
  • Said heater comprises in addition, connecting while obstructing the free space between the two envelopes, the front side of the first envelope and the front face of the second envelope, a plate provided advantageously from a series of perforations to channel and promote circulation air, said plate thus forming part of the face front of the heater.
  • Heater means everything heater likely to be present in a room to be heated, in particular built-in appliances such as inserts and cassettes or stoves with a direct connection or via a chimney to the outside of the room. These heaters can be realized in any type of material (metal, steel, cast iron, etc.).
  • the plate advantageously includes a external overflow from the front of the second envelope, said overflow being able to be used as connection of the built-in appliance on a supporting structure such as a wall or chimney or capable of hiding said fitting.
  • connection between the heater built-in and its supporting structure being produced by adequate means known to those skilled in the art.
  • the perforations or orifices present on the metal plate can have various shapes (round, square, rectangular, triangular, hexagonal, diamond, star or other or a mixture of them) adapted to the aesthetic taste of consumer.
  • the plate with the perforations can be made of any material (metal, ceramic, cast iron, etc.), whose shape, thickness and external appearance are suitable for other materials heating of the invention.
  • This plate can in particular be covered with vitreous enamel, very satin finish heat resistant, paint or finish by graphite deposition.
  • means such as deflectors can be provided and placed on or under said perforated plate so as to improve the diffusion heat in preferred directions of the room to heat, especially in directions where it does not would not be likely to cause disruption likely to obstruct and prevent cold air intake from said room to be heated.
  • Figure 1 shows an insert or cassette according to the state of the art.
  • Figure 2 shows an insert or casette according to the invention.
  • Figure 1 shows an apparatus for heating according to the state of the art, which includes a first casing 2 around a heating body 1, which is adapted so as to ensure the maximum dissipation of heat as well as a vision of fire and radiation optimal.
  • the heater of the invention also has different combustion means suitable for solid, liquid fuel or gaseous used.
  • the heater has also a second envelope 3 surrounding the first envelope 2, and leaving space for a displacement air between the two envelopes to recover the heat from the heater 1 and supply the heat to the room to be heated where said heating appliance.
  • the free space between the two envelopes 2 and 3 is obstructed by a plate 6 which includes perforations 7 and 8 intended to channel the hot air and cold air flowing in the space between the two envelopes.
  • the air flow is thus better directed and its increased speed of flow. This phenomenon causes a feeling of warmth and increased comfort consumer in the room to be heated.
  • Such heaters are usually arranged in the lower part of the rooms to heat to promote the upward flow of heat towards these.
  • the ambient air is channeled at the level of the part lower of the device by penetrating through the perforations or calibrated orifices 8 arranged on the lower part of the metal part or below the metal part.
  • plate 6 may have an external overflow 5 extending beyond the face front of the second enclosure and can be used as a connector of the built-in appliance on a supporting structure such that a wall or a chimney or that can serve decorative hiding such a fitting (not shown on figures).
