Definitions

  • the subject of the invention is a domestic electric heating appliance comprising at least one hollow bar in which is housed an electric heating element.
  • An electric towel rail generally comprises one or more hollow and flat drying bars arranged horizontally and fixed on one or two vertical uprights, each drying bar contains an electric heating element.
  • Such an electric towel rail is for example described in the patent EP-1381255 (Muller).
  • the electric heating elements are of increasing interest because, in particular, of their rapid rise in temperature reducing the duration of heating and, therefore, the power consumption, and the thermal homogeneity obtained providing, in addition to optimal drying of towels or other laundry, excellent thermal comfort felt by users.
  • the heating elements, or cores - or heating body - are independent and housed respectively inside the hollow bars, these elements being electrically connected to a power supply via a control and regulation box (thermostat regulating the duration and / or or the heating temperature) associated, for example, with one of the uprights.
  • a control and regulation box thermostat regulating the duration and / or or the heating temperature
  • flat drying bar towel warmers must be equipped with double insulation electric heating elements.
  • heating elements comprising a bare resistive wire, wrapped around an insulating support sheet. Two other insulating sheets sandwich the resistive wire support sheet, covering it completely to achieve a first electrical insulation. The second electrical insulation is obtained by insulating pieces or spacers between the metal body of the radiator and the two sheets of the heating core.
  • this heating element with double electrical insulation is not particularly suitable for drying bars flat and thin towel rails. Indeed, due to a too large overall size, the heating element is easily housed inside hollow and flat bars. On the other hand, some models of electric towel rails have flat curved drying bars, which requires having heating elements with a certain flexibility to adapt to the curvature imposed by the drying bars. In addition, the electrical insulation of this type of heating element is no longer ensured when water or water vapor appears in the hollow bar.
  • the present invention aims to overcome these disadvantages.
  • the invention aims to provide an electric heater whose design ensures electrical insulation of the heating element.
  • Another object of the invention is to allow easy mounting of the heating element inside a hollow bar and flat, despite the small thickness and / or the curvature of the latter.
  • a further object of the invention is to increase the life of the heating elements installed in the bars.
  • Yet another object of the invention is to optimize the transmission of heat between the heating element and the bar.
  • the invention also aims to provide a towel dryer whose design is simple and quick assembly.
  • the solution proposed by the invention is a domestic electric heater comprising at least one vertical upright on which is fixed at least one hollow bar and flat having two longitudinal edges and two transverse edges, an electric heating element being housed in said bar.

  • This towel 1 comprises a vertical upright 2 or mast, which is for example office wall bracket.
  • the amount 2 consists of a hollow profile, preferably made of a light alloy of the aluminum type, but may be made of another rigid material such as a composite material. It has for example a width of between 2 cm and 20 cm and a height of between 50 cm and 250 cm.
  • Fastening means 20 ( Figures 3a and 3b ) allow to hang the amount 2 on a wall such as a wall, a door or a wall shelf.
  • These fastening means 20 can be in the form of a rail adapted to receive one or more brackets.
  • One or more flat drying bars 3 are fixed on the upright 2. These bars 3 are arranged horizontally and parallel to each other. A transverse end of the bars 3 is secured to the upright 2 by any suitable fastening means such as interlocking, welding, screwing, etc.
  • the bars 3 have, in the representation illustrated in the appended figures, a substantially rectangular, elongate, straight ( Figures 1 to 4 ) or slightly curved ( figure 7 ), with a hollow rectangular cross section and flattened.
  • the opposite and parallel side walls 30 of each bar 3 provide a large heating surface compared to bars of circular cross section.
  • the side walls 30 may be smooth or have elements in relief, such as flutes, these elements in relief to increase the heat exchange surface.
  • Each bar 3 has two longitudinal edges 32a, 32b and two transverse edges 33. These edges 32a, 32b, 33 delimit with the side walls 30, an internal cavity forming space or cavity 31 for receiving and mounting the electric heating element 4.
  • the bars 3 are preferably made of a heat conducting material, typically steel, cast iron, zinc alloy (Zamak) or aluminum. They could, however, be made of a non-metallic material of the polymer or composite type.
  • their length (distance between the transverse edges 33) varies from 15 cm to 1 m
  • their height (distance between the longitudinal edges 32a, 32b) varies from 5 cm to 20 cm
  • their thickness (distance between the side walls 30) varies from 2 mm to 2 cm.
  • the bars 3 are preferably obtained by an extrusion process, and therefore each formed by an extruded profile.
  • the direction of the extrusion is parallel to the longitudinal edges 32a, 32b.
  • the bar 3 being extruded the transverse edges 33 are open. They are closed by removable caps 330 which can be made of a plastic material. In practice, these plugs 330 are interlocked in arrangements 3300 provided for this purpose in bar 3 ( Figures 8 to 10 ).
  • the bars 3 are arranged in several separate groups, so that the spacing between these groups allows the establishment of several towels.
  • the vertical upright 2 is, for its part, in rigid connection with all the groups of bars 2.
  • command and control unit 6 - or thermostat - acting in particular on the duration and operating power of the towel rail 1 it is attached to the vertical upright 2, preferably in the upper part of the latter, which facilitates its use while being located in height.
  • Each bar 3 encloses a heating element 4.
  • the various heating elements 4 are connected together, preferably in series, and the thermostat 6.
  • the electric cables 61 for feeding the heating elements 4 pass into the internal cavity of the upright 2.
  • the heating element 4 is in the form of a flexible cord having a double insulated electrical sheath.
  • the cord 4 comprises an electrical resistor surrounded by a double silicone-based flexible sheath.
  • This design makes it possible to meet the reduced space requirements imposed by flat bars 3 and standards in force imposing double electrical insulation.
  • the cord 4 intrinsically having a double electrical insulation, the latter is kept even if water or water vapor is introduced inside the bar 3. It is therefore not necessary to provide a particular sealing at plugs 330, which simplifies the design and reduce manufacturing costs.
  • the cord 4 is formed of two straight heating sections 4a, 4b connected by a curved section 4c.
  • rectilinear means that the sections 4a and 4b extend in the length of the bar 3 being parallel to, or substantially parallel to, the longitudinal edges 32a, 32b.
  • the rectilinear sections 4a, 4b are connected, at one of their ends, to the curved section 4c, the connections being insulated and sealed by heat-shrinkable sleeves 40. Their other end is connected to a power supply cable 61 which allows the connection of the cord 4 to the other cords of the apparatus 1 and / or the thermostat 6.

  • the rectilinear sections 4a, 4b extend over the entire length of said bar. Their length corresponds substantially to that of the bar 3.
  • substantially is meant that the length of the rectilinear sections 4a, 4b is equal or slightly lower, for example a few millimeters or a few centimeters, than that of the bar 3.
  • the curved section 4c extends in the height of the bar 3. Its length substantially corresponds to the height of the bar 3. By “substantially” is meant that the length of the curved section 4c is equal to, slightly less, for example a few millimeters or a few centimeters, at the height of the bar 3. The length of the curved section 4c may however be greater than the height of the bar 3 to the extent that said section is curved.
  • the rectilinear sections 4a, 4b are each formed by a flexible heating cord having a double electrical insulating sheath of the type comprising an electrical resistance surrounded by a double flexible silicone-based sheath.
  • These cords have a circular section, and have a diameter - or thickness - for example between 4 mm and 10 mm, this thickness being less than that of the bar 3. They could have a square section, rectangular oval, or other.
  • the rectilinear sections 4a, 4b are preferably identical to dissipate the same heating power, and have the same thickness. They could however have different thicknesses, so they do not provide the same heating power.
  • the rectilinear section 4a which is located at the upper longitudinal edge 32a of the bar 3 can provide a heating power greater than that provided by the rectilinear section 4b which is located at the lower longitudinal edge 32b.
  • a towel or a wet cloth is intended to rest on the upper longitudinal edge 32a and there may be an advantage in further heating this edge and / or the area of the side walls 30 located near this edge.
  • the rectilinear section 4a may have a thickness greater than the rectilinear section 4b.
  • the curved section 4c is preferably in the form of a flexible non-heating electric cable.
  • This cable has a double sheath electrical insulation to meet the requirements of current standards imposing double electrical insulation. It connects the straight sections 4a and 4b together.
  • This electric cable has a circular section, and has a diameter - or thickness - for example between 1 mm and 5 mm, this thickness being less than that of the bar 3. It could have a square section, rectangular oval, or other.
  • the curved section 4c is located at one of the transverse edges 33 of the bar 3. From a practical point of view, it is not necessary to heat this transverse edge 33 to dry. a towel or a wet cloth installed on the bar 3. The heating of the side walls 30 is sufficient. The use of a non-heating curved section 4c therefore avoids unnecessarily heating this transverse edge 33 and the plug 330 which closes it.
  • the curved section 4c is in the form of a flexible heating cord having a double insulated electrical sheath of the type comprising an electrical resistor surrounded by a double silicone-based flexible sheath.
  • This cord has a circular section, and has a diameter - or thickness - for example between 1 mm and 5 mm. It could have a square section, rectangular oval, or other.
  • the curved section 4c is in the form of a non-heating electric cable or a heating cord, its thickness -or diameter-is less than that of the rectilinear sections 4a, 4b.
  • the cords 4 are preferably supplied with 24 volts or 230 volts. Their respective heating power is for example between 25 W and 2000 W. The heating is distributed in all the bars 3 and thus allows a good distribution, and therefore better optimization, of the heating power of the towel rail 1.
  • the bar 3 comprises arrangements for receiving each of rectilinear sections 4a, 4b. Another arrangement is provided to receive the curved section 4c. As will now be described in more detail, these arrangements are arranged so that the entire cord 4 is fully housed in the cavity 31 of the bar 3.
  • the bar 3 has two internal housings 31a, 31b. These housings are parallel to the longitudinal edges 32a, 32b and extend over the entire length of the bar 3. They may be located at the longitudinal edges 32a, 32b or more offset towards the middle of the side walls 30 as it appears on the annexed figures. They each receive one of the rectilinear heating sections 4a, 4b. These dwellings 31a, 31b have a rectangular or square section. Their height and width can be adjusted to the thickness of the rectilinear sections 4a, 4b so that the latter are kept tight in the housing 31a, 31b. This configuration has the advantage of keeping the rectilinear sections 4a, 4b pressed against the inner wall of the bar 3, thus promoting the transfer of the calories to the side walls 30.
  • the two inner housings 31a, 31b are separated by two parallel partitions 34a, 34b which define a central channel - or a channel - on both sides of which are located said two housings.
  • the partitions 34a, 34b are parallel to the longitudinal edges 32a, 32b and extend over the entire length of the bar 3. They are spaced from each other by a distance, for example between 2 mm and 30 mm. They have a thickness that corresponds substantially to the thickness of the side walls 30. They are obtained during the extrusion of the profile forming the bar 3, the extrusion die being configured to conform the arrangements of the cavity 31.
  • the partitions 34a, 34b extend perpendicular to the direction of extrusion, that is to say perpendicularly to the side walls 30. They do not extend throughout the thickness of the bar 3. Indeed, they present each having a top edge 340a, 340b which is remote from the inner wall of the bar 3.
  • the distance between the inner wall of the bar 3 and the top edges 340a, 340b is greater than or equal to the curved section thickness 4c, but smaller than the respective thickness of each straight section 4a, 4b.
  • a distance of between 3 mm and 4 mm is compatible with a curved section 4c having a thickness of 2 mm to 3 mm, and rectilinear sections 4a, 4b having a thickness of 5 mm to 6 mm.
  • This geometry is particularly advantageous insofar as the rectilinear sections 4a, 4b remain positioned in their respective housing 31a, 31b. Indeed, their thickness being greater than the distance 'd', the partitions 34a, 34b prevent them from leaving their housing 31a, 31b.
  • the two rectilinear sections 4a, 4b are thus constantly separated to avoid any zone of overheating which would cause premature aging of the cord 4.
  • the curved section 4c can be housed in the space between the inner wall of the bar 3 and the top edges 340a, 340b.
  • the cap 330 keeps in position the curved section 4c in this space.
  • All the cord 4, including the curved section 4c, can thus be housed inside the bar 3. This is particularly advantageous insofar as the transverse edge 33 of the bar 3 where is located the curved portion 4c can be easily closed by a cap 330 and left free, without the need to fix it to a second vertical upright to accommodate a portion of the cord 4 that would come out of this transverse edge 33.
  • a temperature sensor 5 and / or a thermal circuit breaker can be housed in the central channel delimited by the two partitions 34a and 34b.
  • the temperature sensor 5 and the thermal circuit breaker must be remote from the rectilinear heating sections 4a, 4b to be able to correctly measure the temperature of the bar 3. It is therefore appropriate that they can not leave the central channel. For this reason, it is expected that the thickness of the probe 5 and / or the thermal circuit breaker is greater than the distance 'd' above.
  • the central channel therefore has a dual function: it not only keeps the two rectilinear sections 4a and 4b apart, but also serves as a housing for any type of measuring device and / or safety device.
  • the two inner housings 31a, 31b are separated by a single partition 34.
  • the latter is similar to the partitions 34a, 34b described above and obtained during the extrusion of the profile forming the bar 3. It is parallel to the longitudinal edges 32a, 32b and extends over the entire length of the bar 3. It is located in the middle of the side walls 30 and has a thickness that corresponds substantially to the thickness of the latter.
  • the partition 34 extends perpendicularly to the extrusion direction of the bar 3, that is to say perpendicularly to the side walls 30, without however extending throughout the thickness of said bar. It has indeed a summit ridge 340 which is distant from the inner wall of the bar 3.
  • the distance ⁇ d between the inner wall of the bar 3 of the top edge 340 is greater than or equal to the curved section thickness 4c, but less than the respective thickness of each rectilinear section 4a, 4b.
  • a The distance d between 3 mm and 4 mm is compatible with a curved section 4c having a thickness of 2 mm to 3 mm, and rectilinear sections 4a, 4b having a thickness of 5 mm to 6 mm.
  • the partition 34 prevents the rectilinear sections 4a, 4b from coming out of their respective housing 31a, 31b, and allows the curved section 4c to become lodged in the space situated between the internal wall of the bar 3 and the summit ridge 34, at one of the transverse edges 33.
  • the entire cord 4 can be entirely housed in the bar 3.
  • the heating sections 4a and 4b are in contact with the inner wall of the bar 3, at least at one of the side walls 30, more particularly that which, in use, is not located opposite a wall or a support, but which faces the user (the side wall 30 which is visible on the figure 1 ). Also, when the housing section 31a, 31b are greater than the thickness of the rectilinear sections 4a, 4b, it is expected that the latter are each associated with a heat sink 7.
