Description
SPECIFICATION
Cooker
The invention relates to a gas cooker with at least one gas cooking area in which the cooking area is formed by a heat transmitting panel, for example a glass-ceramic panel, which is heated by a radiation burner comprising at least one heatresistant porous or perforated ceramic panel through which the gas-air mixture is conducted upwardly and is burnt in the region of the surface of said panel and an exhaust gas duct is connected to the space between the ceramic panel and the heat-transmitting panel and a baking oven, heated by gas or electrically, is disposed beneath the radiation burner.Different electric or electronic apparatus, for example ignition devices, monitoring devices, clock timers for an automatic cooking or baking operation are required for the operation of the radiation burners and functioning of such devices is influenced by the heat of the baking oven. However, devices of this kind are required to function in a uniform manner irrespective of whether or not the baking oven is in operation. Owing to the effects of heat of the baking oven the air drawn into the radiation burners is also heated and the degree of air suction is therefore also altered during operation of the baking oven since the air volume increases due to heating and suction is volumetric. In addition to the above, relatively high radiation temperatures, for example between 100 and 1 500C, can also occur during continuous operation of the baking oven.Trouble-free operation of such electrical or electronic apparatus is possible only with limited ambient temperatures, the limit being between 60 and 1 000C. Trouble-free operation of known cookers with baking ovens cannot therefore be guaranteed.
It is the object of the invention to prevent or reduce mutual thermal effects between the radiation burner and the operation of the baking oven in such a cooker with a baking oven. To this end, the invention substantially provides that at least one space, closed with respect to the radiation burner, is disposed between the radiation burner and the baking oven, into which said space there extends at least one air inlet port and at least one venting shaft, extending upwardly beyond the cooker panel on the rear of the cooker extends from said space and that the exhaust gas duct of the radiation burner and, where appropriate, the exhaust gas duct of the baking oven which is heated by gas, merges into an exhaust gas shaft which extends upwardly on the rear of the cooker.Direct thermal influence between the baking oven and the radiation burners is avoided by virtue of the space disposed between the radiation burners and the baking oven, thus ensuring that the operation of the radiation burners remains approximateiy uniform irrespective of whether or not the baking oven is in operation. The electrical or electronic devices required for operation of the radiation burners are protected against excessive effects of heat and the supply of air to the radiation burners is not impaired by the thermal action of the baking oven.
This step also prevents the operating controls, disposed above the baking oven on the front escucheon becoming excessively warm. Since an air duct merges into the said space between the radiation burners and the baking oven and because an upwardly extending venting shaft is connected to the said space, there is a constant air circulation, since the upwardly extending venting shaft has a certain chimney effect. Conduction of exhaust gases is improved since the exhaust gas duct also merge into an upwardly extending exhaust gas shaft.
According to the invention, the venting shaft is in thermally conductive connection with the exhaust gas shaft. According to one preferred embodiment of the invention the exhaust gas shaft is surrounded by the venting shaft, more particularly on all sides. This ensures that heat exchange takes place between the relatively hot exhaust gases and the heated air in the venting shaft. As a consequence, the exhaust gas temperature at the exit of the exhaust gas shaft is lower. This step also ensures that the wall, which defines the cooker surface, is not heated by the exhaust gas to high temperatures. Additional heating of the air in the venting shaft results in improved chimney action and therefore in better air circulation in the spaces provided to this end.
According to another preferred embodiment of the invention, the exhaust gas shaft is sub-divided into exhaust gas shaft compartments and a separate exhaust gas shaft compartment is associated with each radiation burner of a cooking place and, where appropriate, with the gas baking oven. This step offers the advantage that draught in the exhaust gas shaft compartment always remains uniform, irrespective of whether only one or several cooking places are in operation.
According to the invention the space between the radiation burners and the baking oven is advantageously sub-divided by a horizontal bulkhead into two chambers and an air inlet port merges into each chamber and the exhaust gas shaft is connected to both chambers. Thermal screening between the baking oven and radiation burners is thus improved. According to the invention, the said horizontal bulkhead advantageously supports the electrical or electronic devices, for example ignition devices, monitoring devices, clock timers and the like, which are required for the operation of the cooker.
This arrangement offers the advantage that these thermally sensitive devices are screened from the baking oven as well as from the radiation burners and are cooled by the air stream which flows through these spaces.
According to one advantageous embodiment of the invention the baking oven is surrounded by a space into which an air inlet port merges and to which the venting shaft is connected. Such.
jacketing of the baking oven achieves further thermal insulation. Jacketing of the top of the baking oven improves thermal insulation with respect to the radiation burners or the cooking places. However, according to the invention it is convenientthatjacketing of the baking oven with the air conducting space is provided laterally, at the top, at the bottom and at the rear so that the ambient zone is also substantially protected against the radiating heat of the baking oven. This feature offers important advantages if the cooker is constructed as a built-in unit. Furthermore, this feature also avoids overheating of devices intended for the operation of the baking oven, for example, grilling motors or air circulation motors.
Combustion air for a gas-heated baking oven is drawn in in accordance with the invention from the space with which the baking oven is jacketed.
According to the invention-the venting shaft which jackets the exhaust gas shaft is advantageously sub-divided by a vertical bulkhead into a front venting shaft compartment and a rear venting shaft compartment, the front venting shaft compartment being connected to the space or spaces between the radiation burners and the baking oven and the rear venting shaft compartment being connected to the space which jackets the baking oven. Such sub-division prevents mutual interference between the venting streams when the radiation burners and the baking oven are simultaneously in operation.
Since the front venting shaft compartment is connected to the space between the radiation burners and the baking oven, and the rear venting shaft compartment is connected to the space which jackets the baking oven, conduction of the cooling air is obtained by a simple construction and on the other hand the front wall of the venting shaft, nearest to the operating person, is heated to a lesser extent when the baking oven is operated.
According to the invention the space which jackets an electrically heated baking oven is conveniently sub-divided into two chambers and air entry ports merge into both chambers and an exhaust gas shaft compartment is connected to the innerjacketing chamber. In this case double jacketing is also advantageous. The innerjacketing chamber, in which the air reaches a higher temperature than in the outerjacketing chamber, is connected to the exhaust gas shaft compartment which would conduct the exhaust gases of a gas heated- baking oven. This feature has the advantage that the construction of the exhaust gas shaft and of the venting shaft remain identical for electrically heated baking ovens and gas heated baking ovens.Conveniently, all air inlet ports are disposed on the front wall of the cooker since this is also always exposed in the case of built-in kitchen units. Conventionally, all air inlet ports are closed by a grid.
Exemplified embodiments of the invention are illustrated in the accompanying drawings.
Figs. 1, 2 and 3 show a cooker with a gas heated baking oven, Fig. 1 being a section along the line I-I of Fig. 2, Fig. 2 being a section along the line lI-Il of Fig. 1 and Fig. 3 being a section along the line Ill-Ill of Fig. 1.
Figs. 4 and 5 show a cooker with an electrically heated baking oven and Fig. 4 is a section along the line IV--IV of Fig. 5 and Fig. 5 shows a section along the line V-V of Fig. 4.
In Figs. 1, 2 and 3, the numeral 1 refers to a cooker with a gas heated baking oven in which the cooking area is formed by a heat transmitting panel 2, for example a glass-ceramic panel. The numeral 3 refers to cooking places. Beneath each of the cooking places 3 there is disposed a radiation burner 4 comprising at least one heatresistant porous or perforated ceramic panel. The gas-air mixture is conducted upwardly through the ceramic panel and burns in the region of the surface 5 thereof. An exhaust gas duct 6 is connected to each radiation burner 4. Beneath the radiation burners 4 the cooker 1 is provided with a gas heated baking oven 7. The exhaust gases of the baking oven 7 are discharged through the exhaust gas duct 8. The baking oven 7 has insulation 9. A venting shaft 10 is disposed on the rear of the cooker.
A space 11, closed with respect to the radiation burners 4, is diposed therebetween and the baking oven 7. The said space 11 is closed by a bulkhead 1 2 with respect to the radiation burners 4 and by a bulkhead 1 3 with respect to the baking oven 7.
The lateral boundary of the space 11 is provided by the side walls 14 of the cooker 1. Air inlet ports 1 5, disposed on the front of the cooker 1, merge into the space 1 The rear of the space 11 is connected to the venting shaft 10.
The exhaust gas ducts 6 of the radiation burners 4 and the exhaust gas duct 8 of the baking oven merge into an exhaust gas shaft 1 6. The exhaust gas shaft 1 6 is jacketed by the venting shaft 1 0. The exhaust gas shaft 1 6 is sub-divided into exhaust gas shaft compartments 1 7 and 18, each exhaust gas shaft compartment 1 7 being associated with each of an exhaust gas ducf 6 of a cooking place 3 and the exhaust gas shaft compartment 1 8 is associated with the exhaust gas duct of the baking oven 7.
Space 11 is sub-divided by a horizontal bulkhead 19 into two chambers 20 and 21. Air inlet ports 1 5 merge into each of the said two chambers 20 and 21. Both chambers 20 and 21 are connected to the venting duct 10. Electrical or electronic device 22, for example ignition devices, monitoring devices, clock timers and the like, required for the operation of the cooker 1, are disposed on the aforementioned horizontal bulkhead 19.
The baking oven 7 is jacketed by the space 23 into which an air inlet port 24 merges. The space 23 is also connected to the venting shaft 10.
The venting shaft 10, which jackets the exhaust gas part 16, is divided by a vertical bulkhead 25 into a front venting shaft compartment 26 and a rear venting shaft compartment 27. The chambers 20 and 21 between the radiation burners 4 and the baking oven 7 are connected to the front venting shaft compartment 26 and the space 23, which jackets the baking oven 7, is connected to the rear venting shaft compartment 27.
Combustion air for the baking oven 7 is drawn in from the space 23 which jackets the baking oven 7.
The cooker shown in Figs. 4 and 5 differs from that shown in Figs. 1 to 3 in that an electrically heated baking oven is provided in place of a gas heater baking oven. The same reference numerals are therefore used for parts which remain the same.
The space 29 which jackets the baking oven 28 is sub-divided into two chambers 30 and 31 and the innerjacketing chamber 30 is connected to the exhaust gas shaft compartment 32. The outer jacketing chamber 31, which does not completely surround the baking oven, merges into the rear venting shaft compartment 27. Air inlet ports 33 merge into both chambers 30 and 31.
The numeral 34 in Figs. 1 and 4 refers to a device intended for operation of the baking oven 7 or 28. Such a device can be a grilling motor or an air circulating motor.
