Definitions

  • the invention concerns environmental heating in boats.
  • boats Some of the specific features of boats are the extremely limited space, a high risk of fire, a great deal of humidity both on deck and below, for the very fact that it is surrounded by water, limited autonomy of energy resources.
  • Subject of the invention is a system of heating boats in general by electricity whereby low-voltage electric energy is directly transformed into diffused warmth, using a low-temperature electric element formed of a highly conductive continuous band, whose thickness is measurable in microns, of constant width having an extremely high ratio between width of the section and thickness, said band being placed flat in lengths laid side by side and electrically insulated, on a thin sheet.
  • Said sheet matches at the front, with electrical insulation with a protective and decorative lamina and at the rear with a heat insulating plate and forms a flat or curved transportable panel, made in units so that its dimensions, and therefore its power and shape, can be adapted to the " various flat or curved areas in the boat.
  • temperature of the electric heating element is advantageously of about 70-80°C Voltage of current applied to the panel is preferably from 12 to 24 Volt.
  • Electric power of the panel is preferably between 50 and 220 Watt.
  • the group formed by the panel's components is held together by a quadrangular frame consisting of four lengths of a metal U-shaped channel joined at the four corners by a corner piece, to form a substantially quadrangular channel open towards the inside of the frame. In this way the frame can be adapted to a group of components of practically any size, using lengths of U-shaped channel corresponding to the sides of said group.
  • the panel made for sailing boats with one or more masts is semi- cylindrical in shape having an internal radius corresponding to the external radius of the masts.
  • a pair of such semi-cylindrical panels can be applied to fit round a mast and be joined by hooks or similar means placed either on the panels or on the mast.
  • the panel is fitted where required in the boat, matching with the walls or placed against the bodies in general present in the different rooms, held in position by hooks or equivalent means for maximum use of space. This is made possible by the absence of high temperatures to cause over heating.
  • the panel can be provided with a supporting stand.
  • the stand is formed of a quadrangular plate associated to two flat triangular lateral parts by hinges between the two lateral edges of said plate and the inclined edges of said lateral parts.
  • the stand When out of use the stand can be made compact for easy storage turning the square plate in line with the lateral parts on the same plane while, when in use, said parts can be turned on their hinges at substantially 90° to said plate to lie behind the quadrangular plate where they are fixed by suitable locking means.
  • the panel is placed on said stand by fitting its lower edge inside U- shaped recesses in the sides and resting it on the quadrangular plate so that it can be used at any point in the boat where warmth is needed to offset adverse climatic conditions.
  • the means for locking the sides of the stand when in use consist of a pair of elastic tongues fixed to the quadrangular plate close to the axis of the hinges and facing towards them, and provided with a U-shaped end hook within which a short rod placed in a recess in the sides near to said hinges can be fitted.
  • the panel is associated to a clothes drier by means of a horizontal oblong box-shaped body applicable to any flat wall.
  • Said oblong body comprises two end downward-facing tabs onto which the panel is articulated, and have at the top an oblong aperture within which a quadrangular frame can freely slide inside which top the end of a grill, on which wet clothing can be hung, is articulated.
  • said frame can be slid inside the aperture in the oblong body and remain lodged between the wall, carrying said oblong body, and the rotated panel which thus remains parallel to said wall for use as a heater.
  • the frame To dry the clothes the frame must be raised till the grill is fully extracted and then turned at 90° to a horizontal position, simultaneously turning the panel up till its position too is horizontal and its heat radiating surface is facing the grill.
  • Automatic means are provided to keep the grill and the panel in said horizontal positions. By heat radiation from the panel the clothes can be dried, and when dry the frame, grill and panel can be returned to their non-operative positions.
  • the front radiating surface of the panel is matched, after interposition of an electrically insulating layer, with the rear surface of a mirror.
  • the panel is best made in various sizes and electric powers to suit it to all the available spaces and specific structures of the boat.
  • the ratio between dimensions of the panel and its electric power are preferably as follows: - panel cm 30 x 30, power 50 Watt,
  • the temperature, which may even not exceed 80°C, of the panels subject of the present invention avoids any risk of fire and makes the boat more habitable as, close to the panels, there are practically no areas that are too hot for ordinary use, or other areas, away from the panels, where temperatures are too low.
  • the low temperatures of the panels and diffusion of heat by radiation ensures in practice that there are no inhabitable areas within the environment warmed in this way.
  • the fact that the panels can be set up in any size makes them adaptable to the dimensions of different parts of the boat where they fit in well with the structural characteristics of said parts.
  • the ease with which the panels can be given any useful shape means that they can be placed where there are flat walls as well as in more complex cases where the walls may even be cylindrical such as round the masts in sailing boats.
  • the possibility of using a single panel both for warmth and for drying clothes solves an ever present problem of drying the laundry in boats where it is almost impossible to do this quickly and easily without creating extra humidity in bathrooms as at present designed.
