Definitions

  • the present invention relates to a kitchen oven, comprising a cavity and a cooling chamber arranged outside of the cavity and provided as a common duct for the joint discharge of cooling air and vapors.
  • a cooling system usually uses a pressure free air ventilation or a pressure forced ventilation.
  • the document EP 0 926 448 B1 describes an air channel above an oven cavity, containing a motor. This motor runs two different fans on one axle.
  • the first propeller leads cooling air from the ambience above into the air channel and the lower propeller promotes the removal of vapor from the cavity through a hole provided in the cavity's top wall. In the air channel, cooling air and vapor are mixed and led to an exit in the front of the appliance.
  • both propellers are dependent on the one particular motor, which does not allow adapting the propeller to different needs with regard to varying receipts or programs to be performed, a varying degree of moisture or temperature.
  • a kitchen oven comprises at least a cavity and a cooling chamber arranged outside of the cavity and provided as a common duct for the joint discharge of cooling air and vapors, and at least one vapor duct for realizing a fluid communication between the cavity and the cooling chamber, in that said vapor duct is arranged such that its first end is in fluid communication with the cavity, and its second end is in fluid communication with said cooling chamber, said cooling chamber further comprising a first fan wheel for blowing the air and vapors out of the oven.
  • the vapor duct comprises a negative pressure device arranged within said vapor duct such that it is capable of sucking air and vapors out of the cavity.
  • Such oven allows for an effective cooling by the air blown through the cooling chamber by the first fan wheel.
  • said cooling chamber serves as or comprises a mixing area in which vapors and cooling air are mixed together. This is possible as the cavity and the cooling chamber are in fluid connection, through the vapor duct.
  • a negative pressure device is arranged which is capable of generating a negative pressure within the cavity and thus sucks the vapor within the cavity out of said cavity and into the vapor duct, from where it enters the blowing chamber and is mixed with the cooling air.
  • the vapor is than taken away by the cooling airflow.
  • the mixture thereof is finally released to the surrounding of the kitchen appliance.
  • the vapor is mixed with the cooling air, preferably immediately after being sucked out of the cavity, the vapor is cooled down and neither hot vapor is exhausted by the oven, nor unwanted condensation will occur or at least be reduced. This is of particular importance as the vapor contained within the cavity may probably comprise moisture to a certain extend.
  • said second end of the vapor duct is arranged in an outlet area of the first fan wheel, preferably such, that a rotating movement of said first fan wheel supports the sucking of the vapors out of the cavity.
  • outlet area preferably refers to the positioning relative to a fan wheel; accordingly, an outlet area is an area located in a region where air is blown to, whereas an inlet area refers to a region where air is pulled from.
  • the second end of the vapor duct may be arranged both, in an inlet and/or in an outlet area of the first fan wheel. Both is considered herein. Where however, the second end is arranged in an outlet area of the fan, it may be advantageously avoided that the vapor, probably hot and moist, which is sucked out of the cavity has to pass the fan wheel.
  • a rotating movement of said first fan wheel supports the sucking of the vapors out of the cavity.
  • This is the case if the second end and the opening and the respective opening of the vapor duct is designed and arranged such that the air blown or pulled by the fan wheel strives said second end and respective opening and due to an injector effect an under pressure in the vapor duct is achieved and/or strengthened which supports the sucking of the vapors out of the cavity.
  • a venturi effect may be advantageously achieved, supporting said under pressure in the vapor duct and, particularly the performance of the negative pressure device. Accordingly the sucking is either more effective, or for having the same effect, the negative pressure device can have a reduced performance.
  • the operation of the second fan wheel be such that an under-pressure resulting from the sucking action of the second fan wheel in the cavity, will not be high, however, sufficient to suck vapor and moisture out of the cavity. It will also be immediately understood that such under-pressure is usually immediately compensated by an air influx through various small openings of the cavity, for example, screw holes, holes for heating elements, central fan wheel or lamps, or the like.
  • said first fan wheel is a radial flow fan wheel.
  • a radial flow fan wheel as used herein is a fan wheel designed and arranged such that, preferably an air influx is an axial air influx and air efflux is a radial air efflux.

  • a person skilled in the art knows various forms of such spiral housing and may design such housing with regard to various needs and advantages, e.g. deceleration of air speed, air streaming, guiding or redirection.
  • the first fan wheel may be an axial flow fan wheel.
  • the negative pressure device is arranged within the vapor duct and is for generating a negative pressure within the cavity. This allows for sucking the vapor within the cavity out of said cavity and into the vapor duct, from where it enters the blowing chamber and is mixed with the cooling air.
  • said negative pressure device is selected from the group comprising a second fan wheel or a suction filter. It is thereby preferred that the negative pressure device is arranged such that is suitable to support the sucking of the vapors out of the cavity. Accordingly, it is to be understood that such negative pressure device, which in general may be arranged such that it can be operated in both directions, is particularly configured such that the negative pressure device generates a negative pressure within the cavity and sucks the vapor within the cavity out of said cavity and into the vapor duct.
  • said second fan wheel is an axial flow fan wheel.
  • An axial flow fan wheel as used herein is a fan wheel designed and arranged such that, preferably an air influx is an axial air influx and air efflux is an axial air efflux.
  • Providing a second fan wheel in the form of an axial flow fan wheel is advantageous in that it allows for a relatively compact and more robust design.

  • the first fan wheel performs such sucking effect, e.g. by a herein described arrangement of the vapor duct, i.e. by an injector effect of the first fan wheel
  • the second fan wheel being an axial flow fan wheel will support said effect and add to the performance of the first fan wheel.
  • both fan wheels act together and support the function of sucking the vapor out of the cavity.
  • the second fan wheel being an axial flow fan wheel will prevent that air from the first fan wheel will be blown or pressed into the cavity.
  • said vapor duct at its first end is connected to an opening in an upper wall of the cavity and/or the cooling chamber is arranged above said upper wall of the cavity.
