Definitions

  • the present invention relates to a kitchen range as defined in the preamble of claim 1.
  • Traditional kitchen ranges comprise two separate fireboxes.
  • the baking oven has its own smoke duct leading into a chimney flue or at least close to the chimney flue juncture, and below the range top there is a separate firebox with a door and an ash box for heating the range top.
  • E.g. publications DE 390090 and DE 1040216 present structures in which no wood is burned in the baking oven but the hot combustion gases from the firebox of the kitchen range can be either directed to heat the range top or passed around the oven to heat it.
  • heating the baking oven properly and uniformly by this method is difficult, if not impossible, because the temperature of the combustion gases falls rapidly as they circulate around the baking oven.
  • the structure is not substantially smaller or lighter than traditional kitchen ranges because the only difference as compared with the traditional solution is that it has no ash box under the baking oven.
  • the object of the present invention is to eliminate the drawbacks described above.
  • a specific object of the invention is to present a new type of baking oven structure that allows more economical manufacture of baking ovens and makes it possible to use them even in places where present fireplaces with corresponding properties cannot be accommodated and that is simpler in structure and therefore cheaper to manufacture.
  • the kitchen range of the invention comprises a baking oven and a first smoke duct for conveying the combustion gases from the oven into a chimney flue, and a range top.
  • the baking oven constitutes the only wood combustion chamber in the kitchen range
  • the first smoke duct conveying the combustion gases from the baking oven substantially directly into the chimney flue.
  • the kitchen range comprises a second smoke duct, which conveys the combustion gases from the baking oven via the range top into the chimney flue to allow the range top to be heated by the combustion gases flowing from the baking oven.
  • a control element is used below the range top to guide the combustion gases. It can be adjusted to two different positions so that, in a first position, it will direct the combustion gases right up to the lower surface of the range top, causing the range top to be heated. In a second position, the control element directs the combustion gases past the range top towards the chimney flue so that the range top is not significantly heated.
  • the control element in its different positions opens alternatively the first or the second smoke duct between the baking oven and the chimney flue juncture.
  • the separate smoke ducts may be implemented as separate channels in the internal structures of the kitchen range, conveying the combustion gases separately into the chimney flue, or the smoke ducts may also combine into a single exit duct that conveys the combustion gases into the chimney flue.
  • the first smoke duct is provided with a first shutter element, such as a damper, flap or valve, by means of which the first smoke duct can be opened or closed if desired, independently of the gas flow in the second smoke duct.
  • a first shutter element such as a damper, flap or valve
  • the second smoke duct may be provided with a second shutter element, flap or valve, by means of which the second smoke duct can be opened or closed independently of the gas flow in the first smoke duct.
  • the kitchen range is provided with a common control element that can be used to direct the combustion gases alternatively between the first and the second smoke ducts.
  • a control element may consist of e.g. a flap valve disposed at the fork between the first and the second smoke ducts.
  • flap valve disposed at the fork between the first and the second smoke ducts.
  • other types of structure can also be used.
  • the kitchen range of the invention wood is only burned in the baking oven, and the kitchen range can be used according to need either in stove mode, in which case the combustion gases flow by the route below the range top, or in oven mode, in which case the baking oven is effectively heated and heat is effectively stored in the brick mass without significantly heating the range top.
  • the location of the chimney flue juncture in the kitchen range may vary relatively freely. It is also possible to have the first smoke duct convey the combustion gases via a chimney flue juncture in the lower part of the structure into a chimney flue while the second smoke duct takes the combustion gases by the range top route via a chimney flue juncture in the upper part of the structure either into the same or a different chimney flue.
  • the kitchen range comprises a baking oven 1 provided with a door 7 and, below the oven, an ash box 9 provided with an ash scuttle 8.
  • a smoke duct for conveying the combustion gases from the baking oven starts from the back of the oven in an upward direction and immediately forks into a first smoke duct 3 and a second smoke duct 2.
  • the first smoke duct starts from the baking oven and the second smoke duct branches off from it immediately after the baking oven.
  • the first smoke duct 3 leads horizontally backward towards the rear corners and, as shown in Fig. 2, downward along the rear part of the kitchen range towards a chimney flue juncture at the lower end, whereas the second smoke duct 2 rises upward under the range top 5, where it bends horizontally rearward and, as shown in Fig. 2, runs downward at the middle along the rear part of the kitchen range towards the chimney flue juncture.
  • the second smoke duct 2 is provided with a shutter element 6, i.e. a damper, by means of which the second smoke duct can be closed or opened for gas flow.
  • the first smoke duct 3 is always open and part of the combustion gases can flow through it into the chimney flue even when the shutter element 6 is open and the range top 5 is being heated.
  • the first smoke duct 3 may as well be provided with a damper or equivalent to allow it to be closed and opened.
  • Fig. 1 shows at the fork between the first and the second smoke ducts a control element, indicated by a broken line, consisting of a hinged damper or flap. In one limit position it closes the first smoke duct 3, and in the other limit position it closes the second smoke duct 2. In a suitable intermediate position, it divides the gas flow between both smoke ducts.
  • the kitchen range may also have only one smoke duct 4 in its rear part, leading downward to convey the gas flow from both the first and the second smoke ducts into the chimney flue.
  • Another possibility is to have one or more downward-leading smoke ducts disposed in one of the lateral parts of the kitchen range, as an alternative or in addition to the embodiments in which the smoke ducts are in the rear part.
  • the kitchen range has an ash removal duct 10 leading from the front part of the baking oven 1 into the ash box 9 below it.
  • the ash removal duct is provided with a hinged or detachable cover 11 and with a fire grate 12 under the cover.
  • embers still aflame in the baking oven can be drawn onto the fire grate, where an intensive air flow can be produced via the ash scuttle 8. In this way, the embers can be quickly and effectively burned out to make the oven ready for baking.
