Definitions

  • the present invention relates to a heating device equipped with thin heating boards that include a graphite layer electrically connected with a power control device so as to dispense even and warm heat energy.
  • Figure 1 shows a conventional heater 10, which includes a case with a curved reflection board 13 and a quartz tube 11 connected between two sidewalls of the case.
  • the quartz tube 11 can be heated to very high temperature so that a plurality of separation grids are used to separate users and the quartz tube 11.
  • the grids are arranged to have a certain width of gaps so as to let the heat to be reflected toward the users.
  • the quartz tube 11 might burn flammable material such as paper sheets or even burn the users who unintentionally touch the quartz tube 11. Besides, only a short distance in front of the heater 10 feels the heat.
  • FIG. 2 shows another heater 20, which includes a plurality of blades 21 and oil is circulated between the blades 21.
  • a heating device 22 is used to heat the oil and the oil circulates through the blades 21 to heat the blades 21 and then, to make heat exchange with the air.
  • the oil is evenly heated and does not have very high temperature so that it will not burn the users. However, the efficiency of heat transfer is low.
  • Most of the blades 21 are coated with a layer of baking varnish which reduces the heat transferring from the blades 21 to the air.
  • the heater 20 is not an energy saving heater.
  • Figure 3 shows yet another heater 30, which is used in a sauna cabinet and includes a plurality of heating tubes 31 which are heated to a high temperature and the case 32 has an open top with grids thereon. Stones 33 are put on the grids to absorb the heat from the heating tubes 31 and release far infrared beams. The stones 33 might burn the users and the far infrared is limited because the stones 33 include limited surfaces. Due to the high temperature of the heating tubes 31, the gap between the heating tubes 31 and the insides of the case 32 has to be wide enough so that the case 32 is bulky.
  • the present invention intends to provide a heating device that has a compact size and the heating boards are so thin that the heat can be efficiently dispensed and does not hurt the users.
  • a primary objective of the present invention is to provide a heating device that comprises a case with a plurality of openings and a plurality of heating boards are installed in the case at a substantially equal spacing and each heating board includes a heating layer which is sandwiched between two isolation plates. Two wires are connected to the heating layer and each wire has a female connector so as to be connected with a male connector of a power line of a power control device connected to the case.
  • Figure 1 shows a first conventional heater
  • Figure 2 shows a second conventional heater
  • Figure 3 shows a third conventional heater
  • FIG. 4 is an exploded perspective view of a heating device in accordance with the present invention.
  • Figure 4A shows another way for connecting covers to a case of the heating device of the present invention
  • Figure 5 shows a perspective view of the heating device of the present invention
  • Figure 6 shows a heating board of the heating device of the present invention
  • Figure 7 shows a cross sectional view of the heating boarding of the present invention.
  • Figure 8 shows that female connectors of the heating board and male connectors of a power line of the present invention are to be connected in parallel with each other.
  • the heating device in accordance with the present invention comprises a rectangular case 40 which is composed of a plurality of posts and transverse bars 48 and a plurality of openings 44 are defined between the posts and the transverse bars 48 in four vertical sides and a top of the case 40.
  • the case 40 is made by plastic or wood.
  • a power control device 42 is connected to a lower end of the case 40 and includes a power line 454 (Fig.8), which has a plurality of male connectors 455.
  • a plurality of slits 43 are defined in the transverse bars 48 on the front side and the rear side of the case 40.
  • a plurality of heating boards 41 are slidably engaged with the slits 43 and a distance between the adjacent slits 43 is between 0.5 cm to 2.5 cm, so that the heating boards 41 are installed to the case 40 at a substantially equal spacing.
  • the each heating board 41 includes a heating layer 45, which is sandwiched between two isolation plates 46.
  • the heating layer 45 is a graphite layer, which can be printed on the two sides facing the isolation plates 46.
  • the isolation plates 46 are made by glass fiber.
  • the heating boards 41 each have a thickness less than 1 mm so that the heating boards 41 can be arranged in parallel at desired spacing.
  • a copper portion 47 encloses the heating layer 45 and has two separated distal ends to which two wires 451 are connected.
  • the wires 451 have female connectors 452, 453 which are connected with the male connectors 455 of the power line 454 to connect the heating boards 41 in parallel.
  • each cover 50 includes a plurality of holes or plates between which slots are defined. The heat is released from the holes or the slots.
  • a plurality of first magnets 49 (Fig.4) are located on the transverse bars 48 and the posts of the case 40 and the covers 50 have second magnets 51 which are connected to the first magnets 49. Therefore, the covers 50 can be easily removed from the case 40 when needed.
  • the first magnets 49 can be replaced with a plurality of metal plates 49A located on the case 40 and the covers 50 have second magnets 51 which can be connected to the metal plates 49A.
  • the heating device uses thin heating boards 41 so that the size of the heating device is compact and the heating boards 41 are easily removed from the case 40 to be cleaned.
  • the heating layer 45 is heated by controlling the power control device 42 and the heat is transferred via the isolation plates 46 and dispensed via the slots or holes of the covers 50.
  • the heating boards 41 have larger area for dispensing the heat so that the heating device has better efficiency than the conventional heaters.
  • the temperature of the heating boards 41 can be controlled by operating the power control device 42 so as to meet different needs such as in sauna cabinets or used in homes.
  • the heat from the heating boards 41 is transferred by radiation and convection so that less energy is lost.
  • the heating layers 45 generate far infrared energy by the electric power which is directly provided to the heating layers 45 so that the energy cost is more efficient than the conventional heaters.
  • the users can touch the heating boards 41 without worry of being burned and the thin heating boards 41 allow the users to install multiple heating boards 41 with less space.
  • the heating boards 41 are connected in parallel with each other so that the number of the heating boards 41 can be easily adjusted as needed.
