Definitions
- the invention relates to a device for supplying odorous substances, in particular for a motor vehicle, according to the preamble of claim 1.
- a nozzle for dispensing active substances is known from DE 100 33 917 A1, a nozzle body which has a connection for an air line having an elongated tube for receiving an active substance cartridge.
- Such an arrangement is normally used in houses, for example in shops, but is not suitable for use in passenger compartments of motor vehicles.
- BEST ⁇ TCUNGSKOP.E This object is achieved by a device for supplying odorous substances with the features of claim 1.
- Advantageous refinements are the subject of the dependent claims.
- the odorant supply in the room air can cause various reactions in humans, which have a positive or negative effect on their mood.
- the positive effects range from relaxation with a low level of arousal to happiness to stimulation with a high level of arousal.
- the negative effects range from apathy at a low level of arousal to depression to stress at a high level.
- a control unit which adjusts the supply of odorous substances such that a current value of an odorous substance concentration in the interior lies in the range between a perception threshold and a detection threshold.
- the mass transfer from the odorant to an air flow for the interior takes place through evaporation.
- the aim is to create a comfortable, stress-free atmosphere in the vehicle by adding odorants, without negative side effects.
- an optimized odorant supply takes place, because in order to be able to perceive the smell of a room, it is not sufficient to enrich it with an odorant of constant concentration.
- the human olfactory cells get used to the odorant, i.e. the fragrance, and the threshold of perception and the threshold of recognition would have to be constantly raised to a higher level.
- control unit comprises a time measurement circuit which alternately activates the supply of the odorous substances into the interior for a predetermined first time period and then deactivates them for a predetermined second time period.
- the time periods for activation or deactivation can depend in advance on the current environmental conditions, for example size (Volume) of the interior, arrangement of the device, etc. for each vehicle type.
- the two time spans can depend on ambient data currently determined by means of sensors, such as the temperature in the interior and / or the ambient temperature and / or the air humidity in the interior and / or the ambient air humidity and / or the air volume in the interior and / or the supplied air volume and / or a fresh air / recirculation ratio during operation to constantly adapt to the existing ambient conditions.
- characteristic maps can be stored in the control unit for a comparison.
- threshold values can be predefined for the individual parameters or parameter groups, at which activation or deactivation of the supply of odorous substances into the interior takes place. However, these threshold values can also be varied depending on the sensor data currently being determined.
- the control unit controls the supply of odorous substances to the interior as a function of predefined data and / or sensor signals.
- the sensor signals of one or more oxidation sensors for measuring the odorous substance concentration are evaluated and compared with the corresponding threshold values.
- a choice between different odorants is provided.
- an odorant that gives a feeling of warmth can be added to the interior during the heating phase, or an odorant that gives a feeling of cold during the cooling phase.
- the dosage can be such that the concentration of the odorant in the vehicle interior is so large that it lies between the so-called detection threshold and the so-called perception threshold.
- "heavy" Fragrances such as the smell of deciduous trees such as birch, beech, cherry or forest earth are used.
- "light" odorants such as mint, eucalyptus, menthol, fresh green, wetted with dew can be used.
- the device is integrated in the center nozzle of an air conditioning or heating system, and it can be independent of it at least at times.
- the device is integrated in the vehicle headlining. This enables draft-free conveying of circulating air from the vehicle interior.
- a filter is provided, only filtering can be carried out or filtering with the addition of an odorant.
- the device is preferably integrated in the center between the driver and passenger seats in the vehicle headlining, so that a uniform distribution over the entire vehicle interior is possible.
- the device is designed as a separate unit, so that it can be easily installed as additional equipment.
- the device preferably has a cartridge or a container which contains the odorous substance or substances.
- the cartridge or container is preferably designed to be exchangeable and recyclable.
- the device can therefore include a blower and / or its own air supply duct into the interior, so that an independent supply of odorous substances into the interior is possible, the used for this purpose If necessary, air can first flow through a filter before it is mixed with the odorant (s).
- Fig. 1 is a sectional and schematically illustrated arrangement according to the first embodiment
- Fig. 2 is a sectional and schematically illustrated arrangement according to the second embodiment.
- a device 1 for supplying fragrance or odor substances is arranged in the middle of the vehicle headlining between the driver's and front passenger's seats in a motor vehicle.
- This device 1 according to the first exemplary embodiment is completely independent of an air conditioning system that is also located in the motor vehicle.
- the device 1 has a blower 2 and a filter, in the present case a hybrid filter 3, which has been optimized especially for pollutants and smoke particles occurring in vehicle cabins.
- three fragrance chambers 5 are provided, closed by means of a closure device 4.
- Each of the three fragrance chambers 5 is connected to an exchangeable and refillable cartridge (not shown), in which different odorous substances are located. If necessary, these cartridges deliver the desired odorant to a fragrance chamber 5 assigned to each cartridge.
- An outlet with an outlet grille 6 is also provided.
- a sensor 8 in particular an oxidation sensor, is arranged in the area between the hybrid filter 3 and the outlet grille 6 and determines the concentration of the odorant in this area.
- a control unit (not shown) is provided, which compares the determined concentration of the odorant with a predetermined threshold value and determines the demand accordingly and controls the supply of the desired odorant.
- the function of the device 1 is as follows: If the device 1 is switched on by an occupant by means of an actuating device, for example a pushbutton switch, in order to filter the air in the vehicle interior, the blower 2 sucks air out of the vehicle interior with low suction speeds, ie with Suction speeds of up to 0.3 m / s. This air is then passed through the hybrid filter 3 and flows through the outlet through the outlet grille 6 and is filtered and fed back to the vehicle interior.
- the occupant additionally selects a fragrance via the actuation device which is connected to the closure device 4 of the fragrance chambers 5, i.e. a fragrance or odorant
- a fragrance or odorant i.e. a fragrance or odorant
- the closure device 4 of the fragrance chambers 5, in which the fragrance is located and which in the present case is directly connected to the actuating device is opened, so that the odorant directly into the area between the hybrid filter 3 and the outlet grill 6 and through the outlet grill 6 can get into the vehicle interior.
- the device for supplying odorous substances is switched off after use of the vehicle and must be switched on again by the user each time the vehicle is started up.
- the closure device 4 of the fragrance chambers 5 is additionally controlled as a function of the determined odorant concentration in the area between the hybrid filter 3 and the outlet grille 6, the closure device 4 being closed when an upper threshold value is reached and when the supply of odorants is activated, the closure device 4 is closed Closure device 4 is opened.
- the selected odorant is dispensed in a timed manner, ie the closure device or the corresponding cartridge is alternately opened and closed.
- the timing is carried out by the control unit depending on the current temperature in the vehicle interior and that on the air conditioning system Set target temperature, with the help of which the effect of the air conditioning system is apparently accelerated by suitable odorants for the occupant, that is to say that the odorants create a feeling of freshness or warmth.
- a part of the air flow is branched off in a corresponding device 11 after a blower 12 and the hybrid filter 13 and passed through a bypass 19 and fed to a fragrance chamber 15 in which the desired fragrance is stored , ie with which one or more cartridges are connected to the odorant (s).
- the two parts of the air stream are then brought together again, the part provided with the fragrance being fed to the main stream via a semipermeable membrane.
- the device is not integrated in the vehicle headlining, but in the central nozzle of an air conditioning or heating system.
- a valve (or flap) at the inlet of the bypass is slowly opened when the control unit is activated and a valve (or flap) at the outlet of the bypass is fully opened immediately, this measure is permitted it to mix the air saturated with odorant in the fragrance chamber 15 uniformly with the main air flow, the length of time and the function by which the valve at the inlet is opened being determined by the control unit, for example depending on the length of time of the deactivation and / or the temperature etc.
