Definitions

  • Object for the invention is an accumulating night electricity hearth, to which belongs a furnace with its structures and in the close neighbourhood of the furnace located heat accumulator, which consists of the accumulating mass for heat accumulation and the heat resistors for heating of the accumulating mass .
  • the accumulating night electricity hearths are used as structures recovering, storing and delivering heat.
  • the mass of the heat accumulator is heated up by means of electric resistors when the electric ener ⁇ gy is favourable, for instance during the night.
  • suitable materials are used, such as rock.
  • the hearth is made to deliver heat into the room space evenly and for a long time.
  • the accumulating mass is placed underneath the furnace, and the heat generated with electric resistors does not spread out to the other structures of the hearth without special constructions. Additionally the disad ⁇ vantage with the present accumulating hearths is the space the accumulating mass occupies underneath the furnace, whereat the furnace rises higher than the accustomed system is, which has an effect on the convenience in use and on the outlook.
  • the purpose of the invention is to bring about an accumulating night electricity hearth, where the by means of electric resistors into the accumulating mass brought heat is spread out well to the other structure of the hearth and from there into the room space, and in which due to the positioning of the accumulating mass the outer casing of the furnace is not overheated. Additionally the aim of the invention is to bring forth a night electricity hearth, in which no special constructions are needed for trans ⁇ ferring of the heat from the accumulating mass to the other stucture, and which to its outlook is like an ordinary hearth.
  • the accumulating mass is positioned on at lea ⁇ t one side of the furnace and arranged to form the side wall of the furnace.
  • the heat resistors are arranged inside of this side wall.
  • the accumulating mass can be placed on one or more sides of the furnace.
  • the accumulating mass is heated alternatively by means of the inside it positioned heat resistors and hereat the heat is spread out evenly on all sides in the other " structures of the hearth and from them into the room space during the electric heating and after that.
  • the accumulating mass is sufficiently large the accumulative effect is obtained as a maximum possible. Due to the positioning of the accumulating mass the outer casing of the furnace is not overheated, and for the heat transfer no special constructions are needed. With minor additions into an ordinary wood hearth an accumulating mass in accordance with the invention can be placed.
  • An advantage of the structure in accordance with the invention is also, that it is not necessary to place underneath the furnace an accumulating mass, and thus the usability and outlook of the furnace are improved.
  • the heat contained in the combustion gas can be recovered in an efficient way.
  • the heat resistors have been placed inside the side walls, whereby they do not come in contact with the combustion gas, which increases their serviceable life.
  • the accumulating mass forms in some applications the whole side wall of the furnace, whereas again in some applications the accumulating mass has been placed on a part of the side wall of the furnace only.
  • the form of the accumulating mass and of the smoke flues can vary in the different applications of the invention.
  • the accumulating mass has been placed on the sides of the furnace in the hearth, in which the combustion gases are not circulated on the side or sides, but they are led directly away from the hearth.
  • the hearth is simple to its structure and with the help of it the heat delivered by the furnace and the electric resistors is recovered efficiently and spread out evenly in the other structures and from them into the room space.
  • figure 1 presents one application of an accumulating night electricity hearth in accordance with the inven ⁇ tion in cross-section and seen from the front
  • figure 2 presents the section A-A in the figure 1.
  • the furnace 1 with its structures, to which structures belong the side walls 2 of the furnace and the outer wall 4 of the hearth.
  • the side walls are formed of soap rock elements and the side walls are arranged to form the accumulating mass of the hearth.
  • the soap rock elements are positioned in two walls in such a way, that between the walls is a space 6, in which the heat resistor 3 is placed.
  • the heat resistor 3 is in this application arranged in the form of a loop and it is fastened inside the space with the help of pins 7 and supports 8.
  • the pins and supports keep in addition the heat resistor at an optional distance from the walls.
  • the soap rock elements are in the night electricity hearth placed in the way presented in figure 1 in such a manner, that their cleavage is parallell with the transfer direct ⁇ ion of the heat, in other words horizontal in this applica ⁇ tion. Hereat the heat is transferred evenly and does not break the structure.
  • the elements are in addition relative ⁇ ly small. When heating with fuel wood the difference in temperature on the different spots of the side walls of the furnace are substantial, but in a structure in accord ⁇ ance with the invention the difference in temperature in the different parts of one element is not such, that it would break up the structure.
  • FIG 2 is presented the sensing element 12 of the thermostat, which is placed between the back part of the side wall and the back wall of the hearth.
  • the heat resistors can be adjusted by taking .into account the temperature of the outer walls of the hearth.

Abstract

La présente invention se rapporte à un âtre électrique à accumulation alimenté pendant les périodes nocturnes de tarif réduit, dans lequel est contenu un foyer (1) avec ses structures et l'accumulateur thermique placé dans le voisinage immédiat de ce dernier, accumulateur qui se compose d'une masse d'accumulation (2) servant à stocker la chaleur et de résistances thermiques (3) servant à chauffer la masse d'accumulation. Dans les âtres électriques alimentés pendant les périodes nocturnes de tarif réduit tels qu'ils sont fabriqués actuellement, la chaleur stockée dans la masse d'accumulation ne peut pas être diffusée efficacement dans le reste de la structure de l'âtre. Dans un âtre électrique de ce type tel qu'il est conçu dans la présente invention, la masse d'accumulation (2) est placée sur au moins l'un des côtés du foyer et forme la paroi latérale de ce dernier, et les résistances thermiques (3) sont disposées à l'intérieur de ces parois latérales.
