DE10257950B3 - Gas-fired heater for indoor and outdoor use ha wind and sight screen above burner to reduce danger of fire and prevent flame being extinguished by wind - Google Patents

Abstract

The heater has a gas burner (2) with down-facing gas intake (3) and flame outlet. A threaded socket (5) of a connection tube (6) extending at right angles to the burner is screwed into gas intake. A nozzle (8) with gas passage of 0,4mm is screwed into the tube end (7). A windscreen (11) extends from the lower end (9) of the gas burner to enclose the air supply bores of the burner. A wind and sight screen (13) extending above the burner has a shell-shaped cover (15) fastened to its upper end (14). The base (17) of the cover is at a distance to the upper edge (18) of the second screen. This screen has several angled support feet (22), and the connection tube is fastened to it. A carrier device (23) is fastened to the cover.

Description

The invention relates to a gas powered heater.

Gas powered heaters, such as for example, radiators have the disadvantage that they are relatively because of their free flame and the resulting risk of fire hardly in wooden huts or the like. can be used. This is particularly the case with high seats that are built very openly additional problem, that at occurring flame extinguished the flame becomes.

An outdoor cooking device is in DE 41 27 077 C2 described. This known device has a gas burner with a gas outlet opening and a flame outlet opening, a connecting pipe being screwed into the gas inlet opening of the gas burner directed downward. Furthermore, since it is to be used outdoors, this known cooking device has a windshield which encloses the air supply bores of the gas burner at a radial distance. This known cooking device is hardly suitable and is not provided as a heater for the aforementioned purpose.

The invention is therefore the object to create a gas-powered heater, on the one hand the risk of fire is reduced to a minimum and on the other hand can also be used outdoors without the flame occurring Wind cleared becomes.

This object is achieved by the Features of claim 1 solved.

Appropriate developments of the invention are in the subclaims characterized.

The gas powered heater according to the invention draws is mainly characterized by the fact that, thanks to the Wind and privacy protection above the gas burner in the area of Flame reduces the risk of fire from the heater to a minimum is. Moreover the flame is protected by this wind and sight protection so that the same not by gusts of wind go out can, causing an uncontrolled gas leakage to health could come. additionally still ensures that arranged in the area of the air supply holes of the gas burner Windbreak for that the Do not flame through gusts of wind go out can.

As is well known, warm air goes up rises, the cover on the wind and privacy screen ensures that first the heat outlet takes place downwards, the heat due to the shape of the cover on the side, i.e. is spread more widely.

Further advantages of the invention result itself from the following description using one in the drawing z.T. schematically illustrated embodiment of a gas powered Heater. It shows

1 a side view of the heater and

2 enlarges an associated gas burner shown partially in section.

This in 1 shown gas powered heater 1 has, among other things, a gas burner known per se 2 (see also 2 ) with a gas inlet opening 3 and a flame outlet 4 on. It is in the downward gas inlet opening 3 of the gas burner 2 a threaded connector 5 one rigid, at right angles to the gas burner 2 extending connecting pipe 6 screwed.

At the outer end 7 of the connecting pipe 6 is a nozzle 8th with a gas passage opening of preferably 0.4 mm, to which a hose with a gas regulator (not shown) is connected, which connects the heater 1 and the gas bottle.

Furthermore, the heater 1 one yourself from the lower end 9 of the gas burner 2 coaxially extending, a radial distance to the same and air supply holes 10 of the gas burner 2 enclosing windbreak 11 on, which ensures that the flame is not blown by wind gusts over the air supply holes 10 can go out.

From the top 12 of the gas burner 2 is a itself above the gas burner 2 wind and privacy protection with a radial distance 13 arranged coaxially, so that wind has no direct access to the flame and this cannot go out. It is also protected by wind and privacy 13 the flame is protected in such a way that if the heater is accidentally knocked over 1 hardly a fire can start.

At the upper end 14 of wind and privacy protection 13 is a bowl-shaped cover 15 provided, which is preferably rectangular and on at least two sides 16 a radial distance from the wind and sight protection 13 having. The floor 17 the cover 15 is at a distance from the top edge 18 of wind and privacy protection 13 arranged, the side edge 19 the cover is facing down and the top edge 18 of wind and privacy protection 13 also encloses at a distance. The cover 15 is on the other two sides 20 of the same with the wind and sight protection 13 connected.

The flame can be seen at the bottom of the wind and privacy screen 13 be ignited, leaving the heat over the top 18 of wind and privacy protection 13 and the floor 17 with the side edge 19 the cover 15 worn down is tested.

For the stability of the heater 1 are at the bottom 21 of wind and privacy protection 13 several feet pointing downwards and sloping outwards 22 arranged (shown here as a so-called tripod), the connecting pipe 6 with at least one foot 22 is inextricably linked.

For transporting the heater 1 is on the cover 15 a carrying device 23 intended.
