Abstract

The baking oven comprises one or more spaces which are heated by combustion gases produced by a burner (in the lowermost area) and circulated by a fan (not shown), and one or more spaces which can be heated by electric elements. After heating the spaces, the gas can either pass directly to the chimney or pass through the spaces to pre-heat them or to assist the electric heating on the way to the chimney. This may be effected by operating dampers which connect the gas duct to the spaces and dampers which control a connection from these spaces to the chimney and from the duct to the chimney. Used for baking oven with burner-heated and electrically heated baking spaces. Increasing energy efficiency, reducing installation cost through lower-rated electrical installation.

Bakoven met qekombineerde brandstof- en elektrische verwarming.Oven with combined fuel and electric heating.

De aanvrage heeft betrekking op een bakoven met meerdere bakruim- ten, waarvan enkele met brandstof en andere elektrisch verwarmd worden. Bij de bekende ovens worden de hete afgassen na de betreffende bakruimten verwarmd te hebben naar de schoorsteen afgevoerd.The application relates to a baking oven with several baking spaces, some of which are heated with fuel and others electrically. In the known ovens, the hot waste gases are discharged to the chimney after having heated the relevant baking spaces.

5 Dit betekent warmteverlies. Doel van de uitvinding is het om deze afgaswarmte zoveel mogelijk te benutten voor het vóórverwarmen of voor het bijverwarmen van de met elektrische verwarming uitgeruste ; bakruimten.5 This means heat loss. The object of the invention is to utilize this waste gas heat as much as possible for preheating or for additional heating of the electric heating equipped; baking spaces.

Behalve dat hierdoor een belangrijke rendementsverbetering verkre-10 gen wordt, kan vergeleken met verwarming van de betreffende bakruimten uitsluitend door middel van elektriciteit, nu ook de aan- sluitwaarde van de elektrische verwarmingsinrichting belangrijk kleiner zijn en de aanschaffings- en aansluitingskosten voor deze verwarmingsinrichting beduidend verlaagd worden. Om dit te bereiken 15 worden volgens de uitvinding de afgassen, die wanneer zij niet voor bij- of voorverwarming van de elektrisch te verwarmen bakruimte benut worden omdat deze ruimten buiten bedrijf zijn, door kanalen naar de schoorsteen geleid. Maar wanneer deze bakruimten wel benut worden, dan kunnen de afgassen door openingen in de bakruimten gevoerd en dan 20 eerst vanuit deze ruimten naar de schoorsteen afgevoerd worden.In addition to achieving a significant improvement in efficiency, compared to heating the relevant baking spaces by means of electricity alone, now the connection value of the electric heating device can also be significantly smaller and the purchase and connection costs for this heating device are significantly reduced. turn into. In order to achieve this, according to the invention, the waste gases which, when not used for additional or preheating of the electrically heated baking space because these spaces are out of operation, are led through ducts to the chimney. However, when these baking spaces are utilized, the waste gases can pass through openings in the baking spaces and then first be discharged from these spaces to the chimney.

De uitvinding zal aan de hand van de tekeningen, waarin een uitvoe-rings-voarbeeld is weergegeven, nader toegelicht worden.The invention will be explained in more detail with reference to the drawings, in which an exemplary embodiment is shown.

Fig. 1 toont een langs-doorsnede van de oven over C-D-E-F van fig. 3. Fig. 2 toont het bovenaanzicht van de oven.Fig. 1 shows a longitudinal section of the oven over C-D-E-F of FIG. 3. FIG. 2 shows the top view of the oven.

25 Fig. 3 toont de dwarsdoorsnede van de oven over fl-B van Fig.1.FIG. 3 shows the cross section of the oven over fl-B of FIG. 1.

De bakruimten 1 en 2 van de oven worden door de verbrandingsgassen van de brander 5 verwarmd.The baking spaces 1 and 2 of the oven are heated by the combustion gases of the burner 5.

Deze warden daar een of twee ventilatoren 6 en 7 op bekende wijze rondgecirculeerd en weer teruggezogen. Dat deel van deze gassen dat afgevoerd moet worden naar de schoorsteen ontsnapt door de opening 8, kanaal 9,12 en 1*+. De openingen met de schuiven of 5 kleppen 10,1D en de kleppen 13,13 zijn dan gesloten.There, one or two fans 6 and 7 were circulated in a known manner and sucked back again. That part of these gases that has to be discharged to the chimney escapes through the opening 8, channel 9.12 and 1 * +. The openings with the sliders or 5 flaps 10,1D and the flaps 13,13 are then closed.

Moeten echter de bakruimten 3 en k waarin zich de elektrische verwarmingselementen 16 bevinden, door de hete afgassen vóórgewarmd of bijgewarmd worden, dan worden de schuiven 10,10 en de kleppen 13,13 geopend, terwijl tegelijkertijd een der kleppen 13 het kanaal 10 12 afsluit.However, if the baking spaces 3 and k containing the electric heating elements 16 are to be preheated or reheated by the hot waste gases, the slides 10, 10 and the valves 13, 13 are opened, while at the same time one of the valves 13 closes the channel 10 12. .

De nog hete afgassen die door de opening 8 in kanaal 9 komen, stromen au door de geopende schuiven 10 in de bakruimten 3 en k, dóórstromen dan deze ruimten over de volle lengte en breedte, geven daarin een belangrijk deel van de afgaswarmte af en verlaten deze 15 ruimten door de openingen 11 en gaan door de kanalen 1** en 15 naar de schoorsteen.The still hot waste gases that pass through the opening 8 in channel 9 flow au through the opened slides 10 in the baking spaces 3 and k, then flow through these spaces over the full length and width, giving off and leaving an important part of the waste gas heat therein. these 15 spaces pass through openings 11 and pass through channels 1 ** and 15 to the chimney.

On de druk waaronder de afgassen uit 7 naar het kanaal 9 gevoerd worden, zó te kunnen regelen dat de juiste trek in de verbrandings-kamer onder alle omstandigheden gewaarborgd is, is in de opening 20 8 een tongvormige klep aangebracht, waarvan de stand regelbaar is en die na afregeling blijvend vastgezet kan worden.In order to be able to regulate the pressure under which the off-gases from 7 are fed to the channel 9 in such a way that the correct draft in the combustion chamber is guaranteed under all circumstances, a tongue-shaped valve is arranged in the opening 20, the position of which is adjustable and which can be permanently locked after adjustment.

Het zal duidelijk zijn dat het verloop van de kanalen en de plaats van de openingen van de kleppen en van de schuiven anders kan zijn, zonder dat aan de kenmerken van de uitvinding afbreuk gedaan wordt.It will be appreciated that the course of the channels and the location of the openings of the valves and of the sliders may be different without affecting the features of the invention.
