Definitions
- the present invention relates to an extractor device and a method for controlling an extractor device.
- Extractor hoods are preferably used in kitchens above a hotplate in order to remove air laden with haze and vapors from the hotplate.
- a distinction is made between recirculation hoods, which extract the air at the hob, filter it and return it to the room, and exhaust hoods, which extract the air, filter it and convey it outside to the outside.
- DE 100 28 333 A1 shows a safety radio circuit arrangement for an extractor hood in which the extractor hood is switched off when it is determined that a supply air flap or another supply air opening, such as a window or a door, is closed. The transmission of whether such a supply air flap, a window or a door is closed is carried out by radio.
- DE 30 40 051 A1 shows a control device for an exhaust air / recirculating air extractor hood, in which the exhaust air or the recirculating air is to be controlled as a function of the pressure of the room air.
- JP 081 70 846 A shows an extractor hood in which a pressure sensor is provided in the exhaust air duct. If the pressure of the exhaust air falls below a predetermined value, a controller concludes that a window or a door of the kitchen is not open, whereupon a supply air fan is started to supply air to the kitchen, so that an excessive vacuum in the kitchen is avoided.
- JP 063 47 081 A shows a supply and exhaust air system for a kitchen with an extractor hood, in which the supply air is controlled via a supply air throttle valve in order to avoid a negative pressure inside the kitchen.
- DE 910 10 95 U1 shows an extractor device with a volume flow measuring device which detects a pressure difference between the extractor socket and the surroundings of the extractor hood and uses this to determine the air volume flow through the extractor hood.
- the device monitors the air flow through the fume hood and warns the user of the fume hood acoustically and optically if the air volume flow exceeds or falls below limits that would lead to an unsafe operating state of the fume hood.
- DE 39 25 975 C2 shows a switchover device for the optional recirculating air or exhaust air operation of an extractor hood, a changeover element being actuated automatically via a control device which detects chimney-bound heaters in the operating state, such that the extractor hood is switched to recirculating air mode when the heater is in operation.
- the changeover element can be a driven flap, for example.
- the object of the present invention is to provide an extractor device and a method for operating an extractor device in which a safe operation of the extractor device in a room with an open fireplace is functionally reliable and can be carried out in a simple manner. This object is achieved by the features of claims 1 or 2 or 12.
- a control device which can be used in a fume extractor device which is arranged in a room and which has a fan, a differential pressure detection device for detecting the differential pressure between the interior space in the room and the external pressure in the area outside the room and a control device for controlling the air flow rate of the extractor device in Depending on the detected differential pressure, it is possible to reduce the air delivery volume if the negative pressure in the room reaches a dangerous level if an open fireplace is operated in the room.
- the differential pressure measurement between the internal pressure in the room and the external pressure in the area outside the room, into which the extractor hood device conveys the exhaust air has the advantage that, regardless of fluctuations in air pressure when the weather changes or regardless of the height of the installation site, there is always a balance between the internal pressure in the room and the external pressure outside the room Room is made.
- the control device or the fume extractor device which is provided with such a control device, works safely and reliably anywhere at any installation location without the need for calibration or readjustment.
- the differential pressure detection device has an internal pressure sensor and an external pressure sensor and a comparison device for comparing the recorded internal pressure and the recorded external pressure.
- the differential pressure detection device has a first sensor line which is connected to the installation space and a second sensor line which is connected to the area outside the room.
- the differential pressure detection device in the room is preferably arranged on the fume extractor device or in the area outside the room or partially in the room and in the area outside the room.
- the differential pressure detection device has a membrane which is connected on one side to the room via a first sensor line and on the other side is connected to the area outside the room via a second sensor line.
- the membrane is therefore subjected to the pressure in the room on one side and the pressure outside the room on the other side.
- a pipe is provided for conveying the haze-laden air into the area outside the room and the second sensor line is laid along or in the pipe into the area outside the room.
- control device controls the fan, preferably in a control loop, in such a way that the internal pressure with respect to the external pressure does not fall below a predetermined differential pressure threshold value of preferably 4 Pascals or that the fan is switched off when the internal pressure with respect to the external pressure falls below a predetermined Differential pressure threshold value of preferably 4 Pascal falls and that the fan is switched on when the internal pressure rises above the predetermined differential pressure threshold value compared to the external pressure.
- a warning signal output device which outputs a warning signal when the internal pressure falls below a differential pressure threshold value of preferably 4 Pascals.
- the warning signal output can be an acoustic warning signal, preferably in the form of an interrupted warning tone, or an optical signal, preferably in the form of a flashing red light or in the form of a display which indicates to the user "open window” or "ventilate room".
- the figure shows an extractor hood in a room.
- the extractor device 1 has a housing 2, a fan 3 and a control device 4.
- the extractor device 1 is arranged in a room 5 with the internal pressure P, via a hotplate 6.
- the extractor device 1 conveys air laden with haze and milling through a pipe 7 through a wall opening 8 into an area 9 outside the room 5 with an external pressure P a .
- the control device 4 has a differential pressure detection device 10, a control device 11 for controlling the fan 3 depending on the differential pressure detected by the differential pressure detection device 10 between the internal pressure P and the external pressure P a . Furthermore, the control device has a warning signal output device 12, which is at a predetermined differential pressure threshold
- I can issue a warning signal between the internal pressure P and the external pressure P a .
- the differential pressure detection device 10 has a pressure sensor, preferably in the form of a membrane, which is connected to the space 5 on one side via a first sensor line 14 and is thus subjected to the internal pressure P 1 and on the other side via a second sensor line 15 is connected to the area 9 outside the space 5 and is acted upon by the external pressure P a .
- the first and the second sensor lines 14 and 15 are designed as flexible hose lines.
- the differential pressure detection device 10 is capable of the pressure difference between the space 5, which has the pressure P, and the pressure in the area 9 outside the space 5, which has the pressure P a , via the first sensor line 14 and the second sensor line 15, capture. Since an extractor device sucks a lot of air out of the room 5, a negative pressure is created in this room 5, which means that the exhausted air from the room 5 has to flow back into the room 5 via gaps on doors and windows. If there is an open fireplace with a chimney in room 5, there is a risk that smoke and exhaust gases from the open fireplace will be sucked back into room 5 through the chimney due to the negative pressure that arises in room 5. Experience has shown that a There is a serious danger if the internal pressure Pj in the room 5 is 4 Pascal lower than the external pressure P a in the area 9 outside the room 5, into which the extractor device conveys the exhaust air.
- the control device 4 When the control device 4 receives the message from the differential pressure detection device 10 that the negative pressure in the room 5 has exceeded the differential pressure threshold value of 4 Pascals, the control device switches off the fan and outputs a warning signal via the warning signal output device 12 so that a user , for example a cook, opens a room ventilation device, such as a window or a door. If the differential pressure detection device 10 determines that the negative pressure in the room 5 has again fallen below the differential pressure threshold value of 4 Pascals, the control device 4 switches the fan 3 on again. As an alternative to switching off the fan when the differential pressure threshold value of 4 Pascals is exceeded, the control device 4 can regulate the speed and thus the air flow rate of the fan 3 to such an extent that the differential pressure threshold value of 4 Pascals is not exceeded. In this way, a certain amount of suction, a so-called emergency operation of the extractor device, can be maintained, while at the same time ensuring the necessary safety.
- a buzzer can be provided, which preferably emits a warning tone, an interrupted warning tone, or an optical signal, such as a flashing red lamp and / or a display on which a warning lights up, such as "ventilating the room” or " Open window “or the like.
- the control device 4 which includes the differential pressure detection device 10 and the control device 11, can be one. Unit can be retrofitted in each existing extractor hood, only a second sensor line 15 in the form of a hose must be laid through the pipe 7 into the area 9 outside the room 5 and the fan 3 must be electrically connected to the control device 4 accordingly.
- the differential pressure detection device 10 for detecting the differential pressure P d between the internal pressure Pj in the space 5 and the external pressure in the area 9 outside the space 5 can be an internal pressure sensor (not shown) instead of the membrane described above. ) and an external pressure sensor (not shown) and a comparison device for comparing the recorded internal pressure and the recorded external pressure.
