Definitions

  • the invention relates to a method for controlling an extractor hood and a control device for carrying out the method.
  • Cooker hoods are mounted in kitchens near a cooking area. Vapors arising during a cooking process can be sucked out of the cooking area by means of the extractor hood. The vapor then flows through a first arranged in the air inlet of the hood fat filter. If the extractor hood is operated in the extract air mode, the extractor hood conveys the fumes and the room air sucked in with the fumes out of the kitchen into the open air. If the extractor hood is operated in recirculation mode, flows through the vapor and sucked with the vapor room air an odor filter and is then blown back into the kitchen.
  • extractor hood covers all types of household kitchen extractor hoods, in particular also extractor doses and well vents.
  • the electrical energy consumption is for household electrical appliances, such as e.g. Washing machines, dishwashers, refrigerators, cookers and hoods an important differentiator and an important selling point.
  • the electrical power consumption of the appliance is determined during certain typical usage cycles.
  • the power consumption of household appliances can be reduced for example by the use of energy-efficient electrical and electronic components.
  • this includes, for example, the use of particularly economical electric motors for driving the fan of the extractor hood and the use of electronic circuits with particularly low standby consumption.
  • the present invention is based on the object, moreover, to achieve a further reduction of the resulting energy consumption in connection with the use of extractor hoods.
  • the heating system or air conditioning system is a device which is independent of the extractor hood and serves for heating or cooling the room air of the same room from which the fan unit
  • An air conditioner can be a fixed installation or a stand-alone unit, the air conditioning is primarily used to cool the air in the room If a separate heating system is provided, this may also be part of the building installation or be formed by at least one free-standing heater.
  • Heating systems and / or air conditioning systems consume a considerable amount of energy for heating or cooling the room air. If a part of this tempered room air is now conveyed out of the room by means of the extractor hood, the energy consumption of the heating system and / or the air conditioning system increases, since the air flowing into the room must be appropriately tempered at night.
  • This energy consumption of the heating system and / or the air conditioning system caused by the extractor hood is referred to below as the secondary energy consumption of the extractor hood.
  • the power consumption of the ventilator fan is the primary energy consumption of the extractor hood.
  • the secondary energy consumption of the hood can be much larger than the primary energy consumption.
  • the invention proposes that the power consumption of the fan Extractor hood depending on the operating condition of the heating system and / or the air conditioning to influence.
  • the per unit time carried outside air volume can be reduced, and that is precisely when the heating system and / or the air conditioning is in operation.
  • the power consumption of the fan is reduced when the heating system and / or the air conditioning unit heats or cools the room in which the extractor hood is located.
  • the heating system and / or the air conditioning on the one hand, and the hood on the other hand a communication device.
  • the power consumption and thus the air flow volume of the fan are reduced when the heating system and / or air conditioning system is in operation.
  • the power consumption of the fan is reduced in dependence on the electrical power consumption of the heating system and / or the air conditioning.
  • the reduction of the power consumption of the fan can also be done here gradually, finely graded and also stepless.
  • As a criterion for the power reduction of the fan only the electrical power consumption of the heating system and / or the air conditioner is used in this embodiment.
  • Other sources of energy such as can be used in a heating system in the burning of fuels, are disregarded.
  • This embodiment of the invention takes into account the actual electrical energy consumption of the heating system and / or the air conditioning system, which among other things also depends on the outside temperature and the set room temperature.
  • the power consumption of the fan can be reduced gradually or continuously. In this way, the fan power can be adjusted individually to the operating situation of the heating system and / or the air conditioning.
  • the power consumption of the fan is the more reduced, the higher the current performance level of the heating system and / or the air conditioner. It is assumed that a high power level of the heating system and / or the air conditioning causes a high secondary energy consumption of the hood when it promotes the tempered room air to the outside.
  • a particularly advantageous method for controlling an extractor hood is when the power consumption of the fan is only reduced when the extractor fan is operated in the exhaust air mode.
  • the extractor hood conveys room air outwards to the outside only in extract air mode, thus generating a secondary energy requirement.
  • the extractor hood is used in recirculation mode, there is no secondary energy requirement and it is not necessary to adjust the fan power consumption.
  • the power consumption of the fan is additionally influenced as a function of a signal via the instantaneous state of the power supply network.
  • information about the state of the power supply network for example a particularly favorable momentary electricity price or a current supply bottleneck with electrical energy, is fed back to the electrical terminals, in the present case to the extractor hood.
  • Such a feature is commonly referred to as a "smart grid”.
  • the power consumption of the fan in response to a signal on the current state of the power supply network is only reduced if at the same time the heating system and / or the air conditioning heats or cools the room in which the hood is located.
  • the heating system and the air conditioning system are out of operation, the full capacity of the cooker hood is available.
  • the operation of the hood would cause a particularly high electrical energy consumption, but there is a reduction in power consumption of the fan.
  • the power consumption of the fan in response to a signal on the current state of the power supply network is reduced when the signal reflects a high utilization of the power grid and / or a current high electricity price.
  • control device for an extractor hood With regard to a control device for an extractor hood, the object stated at the outset is achieved by a control device for carrying out the method described above.
  • the control device preferably has at least one communication interface for communication with an electronic electricity meter and / or with a heating system and / or with an air conditioning system.
  • the communication interface can be, for example, a device for radio communication, a device for data transmission via the power network or a device for data transmission via a separate data line.
  • the figure shows a kitchen with a hob 1.
  • the hob 1 is formed by a stove, which includes a hob and an oven.
  • a fume hood 2 is arranged, which is formed in the present embodiment of a Wandesse.
  • the extractor hood 2 comprises a vapor shield 3, on which a chimney 4 is placed.
  • a vapor canopy 3 is an unillustrated fat filter for separating the fat components from the vapor.
  • a fan 5 is arranged, with which the vapor 9 is sucked below the vapor shield 3 and is blown through an exhaust hose 10 through an arranged in an outer wall 7 of the kitchen wall box 8 to the outside.
  • the extractor hood is thus set up for use in exhaust air operation.
  • a control device 6 is further arranged for the hood.
  • an air conditioner 12 which is formed in the present embodiment of a stationary air conditioner.
  • the air conditioner 12 sucks air from the kitchen and blows them out as cooled airflow 13 back into the kitchen.
  • Both the hood 2 and the air conditioner 12 are powered by an electronic power meter 20 with electrical energy.
  • the extractor hood 2 causes a primary and a secondary energy consumption during its operation.
  • primary energy consumption is referred to the power consumption of the hood 2 itself. This is largely determined by the power level of the fan 5 of the air conditioner.
  • the secondary energy consumption arises from the fact that the extractor 2 cooled indoor air from the kitchen into the Free benefits. A corresponding volume of uncooled air flows through any openings of the kitchen, for example through door and window slots in the kitchen. This volume of air is cooled by the air conditioner 12 using electrical energy. The case of the air conditioner 12 consumed electrical energy is referred to as secondary energy consumption of the hood 2.
  • the air conditioner 12 has a communication interface 14 via which the control device 6 of the extractor hood 2 receives information about the current operating state of the air conditioning system 12.
  • the control device 6 is designed so that when the air conditioner 12 is in operation, the power consumption of the fan 5 of the extractor hood 2 is reduced to a value below a maximum value.
  • the extractor hood 2 can therefore be operated with the air conditioning switched on, but not at full power. As a result, the primary energy consumption, but especially the secondary energy consumption of the extractor hood is reduced.
  • the control device 6 of the extractor hood also processes a signal from an intelligent electricity meter 20.
  • the intelligent electricity meter 20 supplies to the controller 6 of the extractor hood 2, for example, the information about the current electricity price or current supply bottlenecks in electricity in the electricity grid.
  • the controller 6 may process this information in addition to the information about the operating state of the air conditioner 12.
  • the algorithm of processing the information about the power network and the air conditioner 12 can be freely programmed or fixed. It is conceivable, for example, that the power consumption of the fan 5 of the hood 2 is always affected when either the air conditioner 12 is in operation or the smart meter 20 signals a high network utilization.
