    EXTRACTION SYSTEM Inventory sector According to a first aspect, the present invention relates to a system for controlling extraction of steam, mist, etc. from a building. According to a second aspect, the invention relates to a building comprising such a system. According to a third aspect, the invention relates to the use of a system according to the first aspect of the invention.
    State of the art In order to maintain a healthy indoor climate in homes, it is usually ensured that sufficient air exchange takes place so that moist air from humans and human activity is replaced by fresh air at suitable intervals.
    In order to maintain a healthy indoor climate, kitchens and bathrooms are usually equipped with active extraction devices, so that steam and mist that arise during cooking or bathing can be diverted continuously.
    Such an extractor for kitchens is usually called a kitchen fan. A kitchen fan includes a housing that is open at the bottom, a motor-driven air pump and normally also a filter. Alternatively, the suction effect in a kitchen fan is achieved with an external air pump, which is connected to the kitchen fan via hoses or pipes. Such a kitchen fan is usually called a passive kitchen fan.
    A kitchen fan can thus provide for the diversion of steam and frying from cooking, whereby the kitchen fan is normally arranged above the kitchen stove.
    Correspondingly, bathrooms are provided with extraction devices that are intended to be deactivated for extraction during bathing. Such activation is usually done manually by switching on a switch that switches on the extraction, but can be done automatically by letting a humidity meter read the humidity and at a certain level switch on the extraction.
    There are extraction systems on the market for use in homes, these extraction systems include a central air pump, which is connected via hoses and / or pipes to a kitchen fan in the home's kitchen, and possibly also via hoses and / or pipes to one or more ventilation ducts, such as t. ex. may be connected to a bathroom. The air pump comprises an electric pump motor, the on / off state of which determines the actual extraction.
    Such systems operate so that a relay ensures a certain basic air exchange, based on a minimum extraction via the air pump pump motor, and this minimum extraction of the vial air pump pump motor can also switch to a forced extraction, when the air pump pump motor runs at relatively high speed, in connection with the kitchen fan is active in the kitchen. Although these known extraction systems to some extent provide a satisfactory ventilation with extraction of steam, mist and the like from a dwelling, there remains a need for an improved system that is more flexible.
    The object of the present invention is to provide a ventilation system which improves the indoor climate for a household.
    Brief description of the invention This object is achieved with a system according to claim 1, with a structure according to claim 13 and with a use according to claim 14.
    The invention thus relates, according to a first aspect, to a system for controlling extraction of steam, mist and the like from a building, for example a dwelling, wherein the system is intended to be connected to an existing extraction system, the existing extraction system being of the tooth type comprising a central extraction pump, the central exhaust pump comprises an electric pump motor and an outlet for air and one or more inlets for air; wherein the electric pump motor comprises a connection for voltage supply, and wherein the existing extraction system comprises a set of pipes or hoses, through which air can be sucked out via the extraction pump; the system comprising a kitchen fan for use in a kitchen, the kitchen fan comprising a housing which is open downwards, and an air outlet, the air outlet being connected to the downwardly open housing via a flow channel in the interior of the kitchen fan; wherein the kitchen fan comprises a control panel which can generate a control signal; wherein the system is characterized in that it comprises a control unit, wherein the control unit is so configured that it can receive control signals and thereby emit different voltage signals to the electric pump motor.
    According to a second aspect, the invention relates to a building, for example for residential or commercial activities, in which a system according to the first aspect of the invention is included.
    According to a third aspect, the invention relates to the use of a system according to the first aspect of the invention, in a building, for example for business activities.
    With the first, second and third aspects of the invention, an improved indoor climate for one household is achieved. This improvement is achieved, among other things, by being able to control the extraction of air in a considerably more flexible way. At the same time, with a system according to the first aspect of the invention, a continuously weak extraction of air can be achieved; or alternatively achieve an air extraction based on operation alternating with downtime at predetermined intervals, operating times and suction effects during the 24 hours of the day. In addition, the extraction pump can be controlled either manually or automatically, in such a way that the extraction takes place with predetermined suction effects in the extraction pump.

    Thereby, the control system can be set to regulate the suction power of the electric pump motor.
    In a preferred embodiment of the invention according to its first aspect, the control unit 22 has been configured to allow the electric pump motor 4 of the extraction pump to operate at two or more power levels, for example for forced operation and / or basic ventilation operation. This makes it possible to achieve extraction with two or more power levels.
    In a preferred embodiment of the invention according to its first aspect, the control unit 22 has been configured to allow the suction pump electric pump motor 4 to operate according to a predetermined time schedule.
    In this case, the control system can be pre-programmed in order to be able to switch the pump motor on or off according to one or more programs, for example a daily program or a weekly program, which the user can choose from.
    In a preferred embodiment of the invention according to its first aspect, the kitchen fan 10 is constituted by a passive kitchen fan.
    The term "passive kitchen fan" refers to a kitchen fan that does not have its own built-in extraction pump.
    When the kitchen fan is passive, it is easier to control its extraction via an external pump motor.
    In a preferred embodiment of the invention according to its first aspect, the kitchen fan is connected to a damper 24 which can close / open the air passage in the kitchen fan flow duct. A damper in the kitchen fan provides further possibilities to control the air extraction.

    In a preferred embodiment of the invention according to its first aspect, the system also has one or more remote controls 28, which have been configured to be able to emit a wireless signal, the control unit 22 also comprising a receiver for this wireless signal, and wherein the control unit is configured to emit a voltage signal to the electric pump motor based on this wireless signal.
    In this way, the extraction can take place from the extraction from several places in a home, for example a bathroom.
    In a preferred embodiment of the invention according to its first aspect, the system also has one or more electrically controlled dampers or valves 30, for opening or closing the air passage in the pipes or hoses 20, the control unit being configured to emit a voltage for controlling this or these dampers or valves 30.
    In this way, more efficient ventilation is achieved in a home, in that the system can include more extraction ducts than just a kitchen fan.
    In a preferred embodiment of the invention according to its first aspect, the system also comprises - a central extraction pump 2, which comprises an electric pump motor 4 and an outlet 6 for air and one or more inlets 8, 8 'for air; and - optionally one or more exhaust ducts 14, 14 'which can be mounted on a wall or an attic, each of these exhaust ducts having an air outlet 16; a number of hoses and / or pipes 20, these hoses and / or pipes being adapted for connection of the air inlet 8 of the central exhaust pump to the air outlet 12 of the kitchen fan; and optionally pre-connecting the air inlet 8 'of the extraction pump to the air outlet 16 of the extraction ducts.
    In this embodiment, the system can not only be used as a complement to an existing ventilation system, where there is already a central extraction pump, but also as a complete extraction system for homes or offices.
    The invention further relates according to a second aspect to a building 200, for example for residential or commercial activities, in which a system 100 according to the first aspect of the invention is included.
    Finally, according to a third aspect, the invention relates to the use of a system according to the first aspect of the invention, in a building, for example for business activities.
    Reference is made below to the accompanying drawing figures which illustrate the invention. Figure 1 shows the principle of how the present invention is arranged in an existing ventilation system.
    Figure 1 shows a system 100 according to the invention, which is connected to an existing central extraction system for extraction of steam, mist and the like. The system 100 has been installed in a building 200 for housing.
    The system 100 in its widest form comprises a kitchen fan 10 for use in a kitchen, the kitchen fan comprising a housing which is open downwards, and an air outlet 12, the air outlet being connected to the downwardly open housing via a flow channel in the interior of the kitchen fan; and wherein the kitchen fan comprises a control panel 26 which can generate a control signal.
    The system 100 further comprises a control unit 22, which is configured so that it can receive control signals and thereby deliver different voltage signals to the electric pump motor 4. This can be achieved, for example, by means of one or more relays 18, which can in principle be built into the control unit 22.
    Figure 1 shows, as mentioned, a control system according to the first aspect of the invention, built into an existing central extraction system. The central extraction system comprises a central extraction pump 2, the central extraction pump comprising an electric pump motor 4, a single air outlet 6 and two or more air inlets 8, 8 '; and an exhaust duct 14, which sits in a space in the attic above a bathroom, the exhaust duct comprising an air outlet 16.
    A set of hoses / pipes 20 connects the individual components that have to do with moving exhaust air.
    As can be seen, therefore, hoses / pipes 20 connect the air inlet 8 of the central exhaust pump to the air outlet 12 of the kitchen fan; at the same time, hoses / pipes 20 connect the air inlet 8 'of the extraction pump to the air outlet 16 of the extraction ducts.
    The control unit 22 has further been configured to be able to turn on / off the electric pump motor via a wireless signal.
    The control unit 22 is thus configured to be able to control the extraction pump. The control unit is configured to switch on or off the suction pump's electric pump motor 4, possibly by means of one or more relays 18, which can be built into the control unit as activated above when activating one or more programs contained in the control unit.
    The control unit can be configured to be able to switch on the suction pump's electric pump motor 4 to two or more power levels. Optionally, the control unit can be configured to be able to switch on the suction pump's electric pump motor 4 to stepless levels.
    The kitchen fan included in the system is normally a passive kitchen fan. The term "passive kitchen fan" means that the kitchen fan itself does not have a built-in extraction pump.
    Figure 1 shows that the kitchen fan has a control panel 26. The control panel is used to control the electric pump motor 4 of the extraction pump.
    As shown in Figure 1, the system 100 also includes a remote control 28. The remote control has been configured to provide a wireless signal for activating / deactivating the suction pump electric pump motor 4, and / or for controlling the system controller 22.
    The control unit 22 is configured to be able to be controlled via the remote control 28, in that the control unit or a receiver for electromagnetic signals can receive the wireless signal emitted by the remote control. Figure 2 illustrates how a system according to the invention works.
    Figure 2 shows the system 100. The system 100 comprises, as in Figure 1, a kitchen fan 10 for pre-use in a kitchen, the kitchen fan comprising a housing which is open downwards, and an air outlet 12, the air outlet being connected to the downwardly open housing via a flow channel inside the kitchen fan. ; and wherein the kitchen fan comprises a control panel 26 which can generate a single control signal. The system 100 further comprises a control unit 22, which is configured so that it can receive control signals and thereby output different voltage signals to the electric pump motor 4.
    A central extraction pump 2, which comprises an electric pump motor 4, an air outlet 6 and three air inlets 8, 8 ', is part of the existing extraction system.
    The same applies to the first extraction duct 14 and the second extraction duct 14 'as well as the hoses 20.
    The kitchen fan comprises a control panel 26 for controlling the extraction pump 2.
    The extraction pump itself is controlled by the control unit 22.
    The control unit 22 is also connected to a receiver 19 for wireless signals, for example electromagnetic signals as radio signals. The system is supplied with electric current from a voltage source 36.
    The system 100 functions so that a user can control the extraction via the kitchen fan control panel 26. This control panel can be used to adjust the suction power of the extraction pump 2 during cooking, when one normally wants a relatively strong extraction.
    During cooking, a relatively strong extraction is thus achieved through the kitchen fan, and by having both the first extraction duct 14 and the second extraction duct 14 'connected to the suction pump, a relatively strong extraction of air is achieved via these ducts. A damper or single valve 30 (not shown in Figure 2) in the extraction channels 14, 14 'may possibly participate in the regulation of the extraction through them. This adjustment can be performed manually.
    In a particular embodiment of the invention, this control of the damper or valve 30 can be done automatically, by activating the damper or valve 30 electromagnetically, for example via motor control.
    In addition, the kitchen fan control panel can be used to regulate the extraction program for the extraction pump at times when cooking is not in progress.
    In addition to the fact that the entire home's ventilation system can be controlled via the kitchen fan, the degree of ventilation can also be controlled by means of one or more remote controls 28.
    Normally there is also a remote control for each extraction duct 14, 14 '. Remote control control extraction pump 2. This control from the remote control takes place when you want a transient or instantaneous powerful extraction, but also when you want to set the system for a valid ventilation profile over the 24 hours.
