1 2002()19 ACCUMULATING NIGHT ELECTRICITY HEARTH
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 reslstors 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 i~ favourable, for instance during the night.
As the mass of the accumulator for the purpose suitable materials are used, such as rock. In the accumulating hearths it is endeavoured to transfer the heat from the accumulator to the other parts of the hearth and from there into the room space. As also the other parts of the hearth become heated, the hearth is made to deliver heat into the room space evenly and for a long time. In the present accumulating hearths 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 Qpecial 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 theaccumulating mass the outer casing of the furnace is not overheated. Additionally the aim of the invention iB 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 i9 like an ordinary hearth.
The purpose of the invention i8 achieved with an accumulating night electricity hearth, which is charac-terized by that, what i8 presented in the claims.
In the accumulating night electricity hearth in accord-ance with the invention the accumulating mass is positioned on at least one side of the furnace and arranged to form the side wall of the furnace. In addition the heat resistors are arranged inside of this side wall. In the different applications of the invention the accumulating mass can be placed on one or more sides of the furnace. When heating the hearth in the ordinary way with wood or correspond-ing fuels the accumulating mass on the side/sides of the furnace is heated and when the burning is finished delivers heat to the other structures of the hearth and from them into the room space. 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. When 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.

the invention can be placed. An advantage of the structure in accordance with the invention is also, that it is not necessary to place undernsath the furnace an accumulating mass, and thus the usabllity and outlook of the furnace are improved.
In a favourable application of the invention between the sidewall of the furnace, inside which the heat reslstors are positioned, and the outer wall of the 1~ night electricity hearth has been formed a smoke flue, through which the combustion gas has been arranged to be extracted from the furnace. In an other favourable application of the invention inside both of the side walls heat resistors have been positioned and between the side walls and the outer walls of the night elec-tricity hearth smoke flues have been formed. When the combustion gas circulates through the smoke flues it heats up the accumulating mass of the side walls from the other side as well, whereat the differences in temperatures between that on the furnace side of the accumulatlng mass and that on the other side are not too big. In addition 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, wherea~ 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.
In the third favourable application 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 200Z(~19 i8 simple to its structure and with the help of it the heat delivered by the furnace and the electric resi~tors is recovered efficiently and spread out evenly in the other structures and from them into S the room space.
In the following the invention is explained more in detail by referring to the attached drawing, in which flgure 1 presents one application of an accumulating night electricity hearth in accordance with the inven-tion in cross-section and seen from the front, and figure 2 presents the section A-A in the figure 1.
In one favourable application of the electric hearth in accordance with the invention presented in the figures 1 and 2 to the night electricity hearth belongs 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, 2~ 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.
Between the side walls 2 of the furnace and the outer wall 4 of the hearth are formed the smoke flues 5, through which the combustion gas is led out from the hearth. The combustion gas coming from the furnace is firstly led upwards in the furnace and thereafter downwards along the smoke flues, whereat the accumula-ting mass is heated from the both sldes. Finally the combustion gas is led through an in the lower part of the hearth positioned exhaust openin~ to the smoke chimney. Underneath the furnace is in the .i..... .. . . .
