Definitions

  • the invention relates to an oven according to the preamble of claim 1.
  • an upwardly opening flow channel is provided between a vapor outlet opening of an oven chamber and a blower and is traversed in the longitudinal direction by a grease filter.
  • a grease filter At the middle level of the grease filter there is a blower with its suction side and at approximately the same height as the blower and the grease filter there is a vapor discharge duct at the rear boundary of an oven chamber, through which the vapor vapors created in the furnace chamber are fed to the grease filter and then to the blower becomes.
  • the fat-containing vapors this results in a preferred location on the fat filter at which the vapors pass through the fat filter and from the blower is collected.
  • the fatty substance which has been separated from the vapor collects at this point and flows or drips downward from the fat filter into a fat collecting container arranged below the fat filter.
  • the invention has for its object to provide an oven of the type mentioned in the preamble of claims 1 and 2 so that the effectiveness and handling of the device for the treatment of fumes is improved.
  • the vapors emerging from the cooking chamber are passed over a large-area fat filter which, because of the large area, has a large absorption capacity for the fat to be separated out and therefore has a long service life.
  • a long way for the vapors is achieved with this arrangement in both chambers of the flow channel, which leads to a uniform filter effect over the entire filter surface.
  • a grease filter can consist of a paper filter, paper fleece or of expanded metal, plastic or the like and can, for example, be mat-like. The grease filter can be easily replaced in the housing section above the cooking chamber, where it can be pulled out from the front of the oven housing in a horizontal arrangement and replaced as a retrofit part.
  • the vapors are mixed with cooler secondary air from the surroundings of the cooking space, a mixing ratio is set in which the dew point is as low as possible below room temperature. Mixing takes place via a blower, which can also serve as a cooling blower for reducing the outside temperature on the oven housing.
  • FIG. 1 denotes an oven muffle, which can be closed by an oven door 2 and which surrounds a cooking space 3.
  • the oven muffle 1 is installed in an oven housing 4, which is provided on the front above the oven muffle 1 with controls 5 and corresponding display elements.
  • On the back of the oven muffle 1 there is an upwardly directed vapor discharge channel 9, through which the hot and fatty vapors which arise when the oven is in operation can flow upward.
  • a cooling fan 10 is arranged in the interior of the oven housing 4 and is driven by a motor, also not shown. While the vapor discharge duct 9 is located on the suction side of the cooling fan 10, a flow duct 11 adjoins the pressure side of the cooling fan 10, delimited by duct walls 12.
  • the flow channel 11 is traversed approximately horizontally by a large-area grease filter 13, which is designed in a manner known per se so that it allows a flow through a mixture of vapors and normal ambient air and thereby causes a grease separation.
  • the flow conditions are illustrated in the figure by arrows.
  • the hot vapors and a certain amount of secondary air 14 from the housing space or from the surroundings of the oven housing 4 is sucked in by the cooling fan 10, mixed and preferably cooled below the dew point of the room temperature, after which this air mixture is pressed against the underside of the large-area grease filter 13, is cleaned there and is discharged to the outside through a front blow-out opening 15.
  • the blow-out opening 15 has flow guide surfaces 16 inclined upwards, as a result of which the escaping air flow is directed upwards and, for example, does not bother the person standing in front of the oven.
  • the flow channel 11 can extend at least approximately over the entire width of the oven housing 4, as a result of which a very large area of the fat filter 13 is obtained.
  • the grease filter is designed such that it can be pulled out and exchanged from the front of the oven housing 4 as such or as a detachable component of a support frame, not shown, without the need for tools.
  • the amount of secondary air sucked in by the cooling fan 10 and mixed with the vapor 18 can be adjusted or adjusted, for example, by a controllable flap 17.
  • the vapor / air mixture is discharged upwards at the rear of the oven housing.
  • the flow channel is divided into two essentially horizontal sections 11a and 11b by means of an intermediate wall 19.
  • the mixture pressed and cleaned by the cooling fan 10 through the grease filter 13 ' is deflected by essentially 180 ° on the front of the housing and in the second section 11b towards the rear passed where it exits at an air outlet 20 obliquely upwards.
  • the function of the intermediate wall 19 can also be performed by the grease filter by appropriate design. In this embodiment, too, it is provided that the grease filter can be removed towards the front.
  • the fat filter 13 and 13 divides the flow channel 11 into a lower vapor supply chamber and an upper vapor discharge chamber.
  • the grease filters 13 are located on the suction side of the blower 10 in the exemplary embodiments according to FIGS In these exemplary embodiments, longer vapor discharge ducts 9 'are provided, which extend approximately to the middle of the cavity above the oven muffle 1.
  • the fan 10 is arranged above the respective vapor discharge duct 9 'on the back of the oven housing 4.
  • the grease filter 13 extends obliquely inclined from a duct wall 20 of the blower 10 to the front outlet opening 15.
  • the flow duct 11 is divided into two essentially horizontal sections, namely a section 11c which is delimited by the grease filter 13 downwards and through an intermediate wall 19 upwards and which is on the suction side of the blower 10, and in an upper section 11d which is on the pressure side of the blower 10 and leads to the blow-out opening 15.
