Definitions

  • the invention relates to an oven, in particular with a device for pyrolytic Self-cleaning according to the preamble of claim 1.
  • Such an oven is known from the document DE-OS-28 56 094, in the area the opening for the extraction of the vapor a device for measuring the in the extracting Vapors contained moisture is arranged.
  • the moisture measuring device is part of a control device that regulates the air flow through the baking and roasting room.
  • the present invention has for its object an oven in the preamble of claim 1 type to improve so that an automatic adjustment the fume hood to the respective operating mode of the oven is made possible.
  • the knowledge obtained from practice is shown in takes into account in a special way that with different cooking processes in the oven or more with pyrolytic self-cleaning operation with extremely high oven temperature or less vapors. So one becomes only slightly with the microwave operation heated oven try to extract as much vapor and water vapor as possible, for annoying condensation of the vapors, especially at the viewing window of the Prevent oven door largely. On the other hand, it is self-cleaning and If the oven heats up excessively, the periphery of the oven is effective to cool, i.e. by means of a cooling air blower through the muffle wall to dissipate heat escaping to the outside, but not to the inside of the oven Heavily heated air (vapors) used for heat cleaning.
  • the cooling air blower with high suction power to operate, in the former case for the purpose of extracting the vapor from the cooking space the oven and in the second case for cooling the baking room environment.
  • the adaptation of the vapor extraction to the different operating conditions now serves the choke provided in the oven according to the invention, which depends on the temperature and / or the humidity of the fluid flowing through the vapor opening Wrasens automatically adjusted in the sense that at a low oven temperature and at a correspondingly low temperature of the vapor, the flow cross section is as large as possible and at a very high temperature, e.g. the flow cross-section in self-cleaning mode is reduced or closed.
  • This automatic adjustment can be done in use of a bimetal element as a throttle.
  • a bimetal element as a throttle.
  • the temperature drops at a high vapor temperature Water vapor content, so that the aforementioned cooling effect is not takes place and a gradual reduction in the flow cross-section he follows.
  • the oven muffle 1 is inside an oven housing 1 an oven muffle open to the front 2 with surrounding Isolation 3 arranged.
  • the oven muffle 2 can be closed through an oven door 4 that delimits the front is through a glass plate 5.
  • a door handle 6 At the upper limit of the Door 4 is a door handle 6 with recessed grip 7.
  • a motor-driven cooling air blower 9 e.g. a Cross-flow fan
  • a switch room 11 in e.g. an electronic control, an electronic clock 12 and the like. is arranged.
  • the flow is indicated by arrows that sucked in from the outside by the cooling air blower 9 Cooling air indicated.
  • This cooling air flows around the handle 6 and the switch room 11 and is through the flow shaft 8 led out to the front.
  • the drawing does not show that for heating the interior the oven muffle 2, or the food to be stored therein required Agents such as electric heating elements, a forced air fan, a microwave generator and the like.
  • This Means are well known. 1 also shows a vapor opening 15 is provided in the upper oven wall 14, which is followed by a flow channel 16/17 from a first, vertical channel section 16, which runs through the flow shaft 8 and from a horizontal Channel section 17, along the cooling air flow shaft runs and there directly to the Suction opening 13 of the cooling air blower 9 connects.
  • FIG. 2 consists of the vertical channel section 16 again two pluggable and against each other by means of a seal 18 sealed pipe socket 16a and 16b, wherein the pipe socket 16a funnel-like towards the vapor opening 15 is expanded and is surrounded there by the insulation 3.
  • 19 is a throttle designed as a bimetallic element, the up at low ambient temperature is bent and thus the upper outlet of the pipe socket 16b and thus the flow channel 16/17 fully opens and at high ambient temperature or when the flow is very hot Vapors from inside the oven muffle 2 accordingly the arrows in the dashed shown closed position automatically adjusted in which the flow channel 16/17 is at least largely closed is.
  • This closed position is reached at Muffle temperature and thus at a temperature of escaping vapors of about 350 ° C, i.e. at the beginning of a pyrolytic self-cleaning process.
  • the opposite is the case maximum opening position of the throttle 19 obtained during operation the oven at low temperature, e.g. with microwave operation, in an operating mode in which the vapor is relatively cool, but has a high water vapor content having. Since the throttle 19 on a relative cool place at a distance above the oven muffle 2, the water vapor at throttle 19, i.e. condense on the bimetallic element and through it associated cooling effect an adjustment of the throttle 19 in favor the maximum opening position. With increasing Increasing the vapor temperature is gradually reduced of the flow cross section.
  • the flap 20 in the dashed Adjusted position and thus not only the flow channel 16/17 further closes, but practically the whole Cross section of the suction opening 13 preferably in the first Third in which a particularly strong suction effect is achieved is released for the suction of the ambient air, so that a maximum cooling effect in the vicinity of the furnace muffle 2 is obtained.
