Abstract

At least one insulating coated moulded main body part 4 containing carbon particles acts as a heating element and is formed as a space heater, electrical connection means to enable the main body to be connected to an electrical power source. The coating 9 may be rubber or plastics and may be applied by spraying, shrink wrapping or dipping. Air passages/fins 3,6 may be provided to promote heat exchange along with an air control flap 8 to control flow rate. The body may include inner resistance moulding 2, the inner moulding having a higher heat output. Legs 13 and thermal controls are added after coating. The coating may be resilient and the moulded material concrete or brick-forming material which when set may acts as a heat storage mass.

Description

IMPROVED SPACE HEATING APPARATUS The present invention relates to an improved heating apparatus and in particular one wherein a solid mass or body is heated by electricity and then radiates and convects thermal energy into the surrounding space.
Night storage or"off peak"electric heaters are known comprising an electric heating element separate from but juxtaposed by being sandwiched between heat thermal storage bricks or blocks which are housed in a protective and decorative separate outer housing with vents.
Recently there has been developed a cementatious product or composite containing carbon which is electrically conductive and which heats up when current is applied so as to act as a heating member.
According to the present invention an improved space heating apparatus comprises as the main heating means or element, at least one moulded or formed main body part containing carbon particles such as to make the body electrically conductive but of a sufficient resistance to generate heat, electrical connection means to enable said main body to be connected to an electrical power source, and a rubber or plastics or other material coating for at iast the main body for providing electrìcai insulation of the body whilst at the same time permitting heat to be conducted therethrough.
The main body may be of composite material such as concrete or brick-forming material or other like moulable and settable material containing carbon particles or other electrically conductive material such that the body is electrically conductive when set or cured but of a resistance so as to generate sufficient heat for heating purposes and such materials are known and have recently been developed.
The present invention utilises such electrically conductive heating materials and proposes for such to be moulded in a desirable and/or useful shape and for the material then to be set or allowed to set and then coated in an electrically, non-conductive material (dielectric material) such that the body is safe for use without a further housing, whilst permitting heat to be conducted and convected therefrom. Such plastics material should preferably be soft to the touch and leasing to the eye.
Preferably the main body part has one or more through passages for providing passages for the flow of air by cons ection. Alternatively or additionally, heat dissipating fins or projections will preferably extend from said body.
The coating may be provided by spraying, dipping or shrink-wrapping.
If there should be no danger from the electric current passing through the main body, then the coating need not be of dielectric/non-insulating material.
The mass of the moulded main body will preferably be such as to act as an off-peak or night storage thermal energy store to enable advantage to be obtained from cheaper electric tariffs and suitable timing means incorporated in the heating apparatus control.
The coating material will normally be suitably finished and surfaced to provide an attractive finish.
Thus, also according to the present invention a space heating apparatus comprises an outer body part moulded or formed from a material containing carbon particle such as to make the body electrically conductive but of sufficient resistance to generate heat when current is passed therethrough with said body coated in a dielectric material and with said body formed so as to have an inner cavity for receiving a inner body part also moulded or formed of a material containing carbon particles such as to make the body etectricatty conductive and of sufficient resistance to generate heat when current is passed therethrough with said outer and inner bodies preferably being spaced apart so as to provide passages for the flow of air, from a lower region of the combination to an upper region and electrical connection means connected to the inner and outer bodies. Preferably the inner body will have a passage or passages therein for the flow of air.
The invention will be described further, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a schematic perspective view illustrating a heating apparatus or heater according to the invention; Fig. 2 is a traverse section through the heater of Fig. 1; and Fig. 3 is a schematic plan of the heater of Figs. 1 and 2.
An electric heating apparatus or storage heater 1 is illustrated in Figs.
1-3 and comprises a main inner body 2 formed of a moulded material containing carbon particles which make the body electrically conductive such as to generate heat and having at least one inner convection passage 3 formed therein extending from a lower region to an upper region so as to enable cool air to enter at the bottom and rise to the top as it is heated, and a moulded main outer body part 4 of similar material cnntaining carbon p2dssCleS which make the body electrically conductive and of a sufficient resistance to generate heat when electrical current is passed therethrough but generating heat of a lesser temperature than the inner body 2 with said outer body 4 being shaped so as to have an interior space which contains the body 2 therein and defines spaces 5 and 6 extending from a lower region upwardly to an upper region for the flow of air and has three outlet vents 7 at the top of the unit and in the region of which an outlet control means in the form of a damper plate 8 with suitable control means (not shown) is provided.
At least the outer body member 4 which is of lower resistance or such as to generate a lower temperature than the inner body 2, is coated in electrically insulating plastics material 9 such as by being dipped thereinto and such as to provide a leasing outer surface and/or colour. The inner side of the front panel or portion 10 at least of the outer body 4 has a ceramic fibre or the like insulating material 11 as a lining thereof and such may be provided on all interior surfaces of the outer body 4 in the region of juxtaposition where it faces the inner higher temperature body 5.
An aperture is provided in the base of outer body 4 of such of size as to enable the inner body member or inner heater 2 to be inserted into the or outer heater 4 prior to securement to the legs 3 which hold the components together.
The number of air slots or holes through the heater will be selected bearing in mind the insulation, to control the temperature/storage property of the heaters. Thus cool air will enter at the bottom of the heating apparatus via aperture 12 and flow along passages 3,5 and 6 and be heated by the heating units as it flows thereover and will exit via upper apertures 7.
In Fig. 1 an electrical connection 14 is schematically illustrated and a switch 15 possibly with a thermostatic control wit)beprovidedandbe connected to a metal electrical conductor which connects with the inner and outer bodies to supply the requisite amount of electricity to produce the desired heating effect. The switch/thermostat 15 will normally be added after the coating of plastics material.
The centre body 4 at least will be of composite electrically resistant material produced or otherwise controlled to limit the temperature to a maximum of 60 or equivalent to the temperature of a centrally heating radiator.
The outer body unit 4 will be formed to provide a desirable visual effect and coated in plastics material which will act as a thermal insulator and electrical insulator and should be leasing to the eye and soft to the touch.
