Definitions
- the invention relates to a warm air heater according to the Preamble of claim 1.
- the invention relates to a method according to the preamble of claim 3.
- Chemine-like warm air heaters are already known at which warm air in the upper part of the furnace or fireplace area freely in neighboring Living space is blown out.
- the heat storage capacity of such However, heating devices are limited.
- So-called small stoves with air chambers which only one have a small storage volume, and have the disadvantage that the The base of the base remains practically cold because the heat is on the upper part of the oven concentrated, resulting in an unsatisfactory heat distribution.
- the object of the invention is to be achieved, one with solid fuels heatable warm air heating device with high efficiency create a, which extends over the entire furnace height to the base, uniform heat emission through air circulation Warm air with high heat storage capacity made possible by storage stones.
- the hot air heating device according to the invention is in the license plate of claims 1 and 3 defined.
- the warm air does not escape into the living room, but causes it Heat transfer to the storage stones in the form of circulating in air chambers Circulating air.
- a fan ensures that there is constant air circulation takes place and the base foot is also heated. This will a largely uniform heat radiation over the entire furnace casing reached, the storage stones a high heat storage capacity and the heat slowly increases due to internal circulation release the ambient air.
- the individual heat storage stones can be part of a warm air heating device preferably natural stones with the help of clip-like Ironing can be held together in a particularly simple manner without that a connection by mortar or the like is necessary.
- the heating device contains a metal - preferably sheet steel or cast iron - existing heating insert 1, such as such per se from chemical plants are known.
- a fire grate 2 belongs to this heating insert 1, above which the firebox 3 is located.
- This firebox 3 can be Close at the front by a pivoting or sliding door 4.
- motor 10 which is a radial fan drives the circulation of the warm air.
- the furnace casing consists of stacked heat storage stones 12, especially natural stones such as soapstones. It other heat-storing materials such as chamotte, Granite slabs or the like are used, which are at most outside can be covered with tiles or plastered.
- the furnace is closed at the top by a not shown Cover, in which there is only an opening for the chimney connection pipe 6 is located.
- the outlet of the smoke pipe could also be in the back can be arranged on the rear wall.
- the circulating air is on the one hand through the combustion chamber 3 surrounding metallic walls of the heating insert 1 heated and also also from the outside of the chimney 5.
- This chimney 5 thus acts as a heat exchanger.
- the air thus comes from the radial fan located in the base area 8 into the air chamber 14 and through the air chamber on the Back of the combustion chamber upwards into the area of the chimney 5, whereby it warms up.
- the air is directed downwards through an air baffle 18 the air chamber 15 is deflected and finally reaches the base area 8 back to the radial fan, as indicated in Fig. 1 with arrows is.
- a nozzle 11 in the Conduct cavities 21 of the seat 22 and / or another extension 36 are at the seat 22 and when mounting for better visibility the cavities in which the warm air circulates are cut away.
- the warm air thus circulates in the form of a closed one Recirculation system and after the heat is given off to the storage stones 12 returned to the intake manifold 11. So that the connection for the Seat 22 can be attached either on one side or the other can, there is a nozzle covered with a cap 19.
- the furnace casing consists of individual heat storage stones joined together 12. So that they are held together securely in their position 3, there are mounting devices.
- the Heat storage stones which can be natural stones, for example on the top of the stone and in the case of stones that are on top of each other be layered, also on the underside open slits 32 attached. At the end of the slot there is one opposite the slot depth deeper hole.
- the stones to be connected lie with their abutting surfaces 24 against each other.
- Stones with a slot arranged in mirror image become a metallic one Bracket 26 inserted into the slot 32 of both stones 23. These brackets 26 have a bulbous middle part 34 which engages in the slots 32.
- each Lugs 30 extend - in relation to the center line 28 - to the opposite Sides and engage in the holes at the slot ends.
- the slot depth is chosen so that the bracket 26 only up to about the center line 28 dip into the stones 23.
- the top layer of the stones uses brackets that run along the Center line 28 are halved. This secure mounting of the stones 12 relative to each other, the use of mortar or the like can be dispensed with become.
- This warm air heating system can come in different sizes and shapes be built with different materials.
