Definitions

  • the subject of the invention is a heating appliance comprising at least one heating vertical upright on which drying bars are installed.
  • It relates to electric heating appliances, and more particularly to the field of electric towel radiators.
  • Electric towel radiators generally have at least one vertical upright on which drying bars are installed.
  • a heating electric cord is generally housed in each of the bars.
  • Such towel radiators are for example described in the patent documents FR3088817 , FR3036466 , FR3027184 , FR3025416 , FR3022131 Where FR3014454 on behalf of the plaintiff.
  • the patent document FR2897675 (ATLANTIC ) describes a towel radiator comprising at least a first heating zone corresponding to the drying bars and at least a second heating zone, not intended to be covered by towels.
  • This second heating zone corresponds to the vertical uprights on which the drying bars of the first heating zone are fixed.
  • each vertical upright incorporates an electrical resistance playing the role of a convector with an air outlet via multiple openings in the front.
  • FR2897675 In practice, the solution described in FR2897675 is not completely satisfactory. Indeed, the integration of the second heat source in the amounts of existing radiators proves to be particularly complex and costly in time and labor, because it requires modifying the electrical wiring and the assembly of these amounts. .
  • the vertical uprights are generally encumbered with the electrical wiring of the heating resistors of the drying bars. However, these electrical wirings risk being damaged by the heat source integrated in said uprights.
  • FR2897675 suggests installing an air outlet via multiple openings on the front, but this solution is not aesthetically acceptable. It would be possible to increase the section of the vertical uprights to obtain a bearable temperature, but this solution is not yet aesthetically acceptable.
  • the upright is formed by a junction bar covered with a cover.
  • Part of a heating cable is housed in a groove of the splice bar so that the post can be heated.
  • the evacuation of calories out of the amount is particularly bad because of the cover which prevents this evacuation.
  • the electrical wiring installed in the upright runs the risk of being damaged because of the excessively high internal temperature.
  • the second electric heating element can now be easily installed in the upright by housing it in the arrangement provided for this purpose, all the stages of the installation being able to be automated. Furthermore, a substantial part of the thermal energy produced by the second electric heating element is dissipated outside the internal cavity of the upright from the wall against which said second element is in direct contact. The temperature in the cavity is then quite bearable for the electrical wiring housed there. And the second heating zone can be another drying zone.

  • the figures 6a and 6b illustrate such a solution where two second heating elements 4a, 4b are integrated in the upright 3. Each second heating element 4a, 4b is in direct contact with a distinct zone of the internal face Pi of the wall P delimiting the internal cavity 30.
  • the upright 3 can incorporate as many second heating elements as there are walls of the internal cavity 30.
  • the heating elements 4a, 4b are of the type described with reference to the figures 2a, 2b , 2c , 3a , 3b , 3c , that is to say independent heating elements added in the upright 3.
  • the heating elements 4a, 4b are installed against flat faces of the wall P delimiting the internal cavity 30, the fins 620a, 620b are straight or flat so as to have a maximum contact surface between the heatsinks 6a, 6b and said faces.
  • the heating elements 4a, 4b were installed against curved surfaces of the wall P, the fins 620a, 620b would have a corresponding curvature.
  • the internal cavity 30 has fittings into which the second electric heating elements 4a, 4b are inserted so that said second elements are in direct contact with distinct zones of the internal face Pi of the wall P delimiting said cavity.
  • These facilities are of the type described with reference to the figures 2a, 2b , 2c , 3a , 3b , 3c , that is to say formed of slides 330a, 330b configured so that the sections 6a, 6b are able to be inserted longitudinally into the internal cavity 30, by sliding in said slides.
  • the heating elements 4a, 4b are of the type described with reference to the figure 4a , 4b , 5a and 5b , that is to say with housings in which the cords 5a, 5b are installed, directly integrated into the wall P of the internal cavity 30, at the level of the internal face Pi.
  • Cords 5a, 5b are of equal power and each dissipates only half of the total power. Their surface temperature is then greatly reduced, with attenuated thermal radiation, in comparison with the solutions described above with a single heating cord.
  • one or more features disclosed only in one embodiment may be combined with one or more other features disclosed only in another embodiment.
  • one or more features disclosed only in one embodiment can be generalized to the other embodiments, even if this or these features are described only in combination with other features.
