Gas-heated cooking and heating device

The present invention relates to a gas-fired cooking and heating device, in particular for use in closed Clearing.

It is common practice for gas-fired cooking and heating devices to be separated are executed. This is especially true for devices that are used in small spaces, such as D. used in caravans. Since the heaters in particular are kept in operation for a long time, special care must be taken with the exhaust pipe are used, while the cooking appliances, which are mostly only in operation for a short time, are generally harmless Effect. For this reason, the a normal gas stove and a separate, relatively expensive heater installed in a caravan.

It is the object of the present invention to provide a combined To create gas-fired cooking and heating equipment that can also be used in relatively small enclosed spaces. In addition to the proper functioning of the cooking process, the device should effective heating of the surrounding room

The task is solved in that the cooking and heating areas combined in one device and completely sealed off from the surrounding space in terms of supply air and exhaust gas.

The main advantage of the present invention is that only one device for cooking and heating is necessary. In addition, you can boil or heat for as long as you like without the surrounding space being enriched with gases fresh air for combustion is withdrawn from this room.

Further details, features and advantages of the invention erge- h ben from the following description of the \ usführungsbeispiele, one of which is shown in the drawing.

In Fig. 1 there is a gas burner Io directly under one Ribbed plate 12 in a burner space 18. separated by a boundary wall 22, an air supply chamber 14, which is provided with an air inlet opening 16 at the bottom. The air supply chamber 1 ^ i and the burner space iß are means the slots 2o in the boundary wall 22 are connected to one another. A burner trumpet 2't with the first air intake is located in the air supply chamber 14.

In Fig. 2 it can be seen that a piezo-electric spark igniter 26 and a gas regulating valve are located in a special recess 32 outside the air supply chamber I ^. The piezo-electric spark igniter 26 is connected to two electrodes Jo in the vicinity of the burner via an ignition cable 28. The piezoelectric spark igniter 26 and the gas regulating cock are operated via an external operating button 36 and an external regulating button Jk on the front of the cooking and heating point. The focal point is provided with a fold-away cover 38 with slots Ίο.

In FIG. 3, slots k2 are provided on the front side of each cooking and heating point, through which it is possible to observe the flame through an inner viewing window kk assigned to each burner. It can also be seen that the combustion chambers 18 are connected to an exhaust port 46 on the rear side.

The ignition of the gas burner Io takes place by actuating a outer control button 36, which acts on a piezo-electric spark igniter 26, whereby by means of an ignition cable 28 and two electrodes 3o located in the vicinity of the burner generate an ignition spark. The ignition can therefore be completely closed Device. If the gas regulating valve is at least partially opened by means of an external regulating button 3 '* the gases emerging from the gas burner Io are ignited. The ^ flames act directly on one above the gas burner Io located gas-impermeable rib plate 12 and thereby indirectly heat that on the top of the rib plate 12 located food.

The fresh air for the combustion is fed from the open air via a corresponding duct (not shown) in the direction of the arrow through the air inlet opening 16 on the underside of the device into the air supply chamber l * t. In this is the burner trumpet 2k with the first air intake. l'ber the

The air supply chamber Ik lies in the burner space 18, these spaces being separated from one another by a boundary wall 22. In the middle, this boundary wall 22 is pierced by the angled part of the burner trumpet 24, so that the actual gas burner Io comes to rest in the burner space 18. The secondary air is introduced from the air supply chamber Ik via corresponding slots 2o in the boundary wall 22 into the burner space 18. The slots 2o are formed from a three-way divided annular gap which is placed around the gas burner Io. The piezo-electric spark igniter 26 and the gas regulating valve are located in a recess 32 which is separated from the air supply chamber Ik and the burner chamber 18. Each cooking and heating point can be covered separately by a fold-away cover 38 with slots ko .

On the front of the operator panel , viewing slots k2 are assigned to each cooking and burning point, through which it is possible to observe the flame through an inner viewing window kk assigned to each gas burner Io. In addition, the flames are protected by thermo-electrical ignition fuses, so that the gas is automatically switched off after a certain time if the flame fails.

The exhaust gases are led into the open air from the burner spaces 18 connected at the rear via a gap in the direction of the arrow via an exhaust nozzle kG and a corresponding exhaust shaft. In order to improve the thermal circulation of the room air and the associated heating effect, the exhaust duct is enveloped at a distance with a second pipe (not shown). This begins above the floor and ends below the ceiling, with the pipe open at the top and bottom. The increased temperature of the exhaust pipe creates thermal buoyancy, which sucks the cold air from the floor and circulates it.

ORlGSMAL BATHROOM

The main advantage of the cooking and heating device is that it has two functions, namely cooking and heating, from one Device are fulfilled and that the surrounding room air is neither used for combustion nor enriched with exhaust gases. The device is particularly suitable, for example, for installation in caravans, where it is installed in the sink, for example and can be used as a cooker as well as a heater. An additional pipe enveloping the exhaust duct is achieved that Even with a relatively high cooking and heating device, the feet are cold due to the good thermal circulation of the room air is avoided. Even during the actual ignition process, no exhaust gases can escape into the surrounding space, as the ignition occurs during completely closed device is carried out. The operational safety is ensured by built-in thermo-electrical ignition fuses significantly increased, which cause an automatic shutdown of the gas in the event of a flame failure. Also can Despite the closed device design, a flame observation from the front of the device through appropriate viewing windows take place. The device also has a simple structure and a robust design. Compared to conventional cooking and Hexzexnrxchtungen the device can be manufactured relatively inexpensively. By stringing together several cooking and Heating points, the number of lighting points can be varied to a large extent. Because each focal point on the front of the device two clearly distinguishable rotary knobs for operating the ignition and gas regulation incorrect operation is avoided by confusing the various operating conditions.
