The operating characteristics are, for example, a noise level of the device during operation, dimensions of the device, filters and a light emitted from the device.DISCLOSURE OF THE INVENTIONThe invention aims to improve the sleep of a user by means of an air treatment device. More specifically, the device according to the invention makes it possible to configure an operation of the device depending on the sleep phases of the user, in order to facilitate the sleep, maintain the sleep or prepare the waking. An embodiment relates to an air treatment device comprising at least one air treatment unit and a control unit, wherein the device is configured to receive at least one indication regarding a physical and / or physiological activity of a user and to control at least one operating parameter of the at least one air treatment unit depending on the at least one indication regarding the physical and / or physiological activity of the user.The air treatment unit comprises modules with which treatment, i.e. an effect on the air in a room, can take place. The processing unit can comprise a filter module with a filter for filtering air or a disinfection module with a UV-C lamp for disinfecting air.The control unit can in particular comprise a controller for controlling the processing unit. The controller may also perform processing of the at least one indication relating to the physical and / or physiological activity of the user.An indication regarding the physical activity of the user corresponds to an indication for the movement of the user such as acceleration, speed, frequency, amplitude, etc.An indication regarding the physiological activity of the user corresponds to an indication regarding the body of the user such as temperature, heart rate, breathing rate, blood pressure, pulse, etc.The device according to the invention receives the indication regarding the physical and / or physiological activity of the user and controls the air treatment unit in dependence on this indication. In particular, the processing unit changes the at least one operating parameter of the air processing unit.In this way, the air conditioning unit adjusts its operation at least in real time to a state of the user. It has namely been shown that the quality of the room air in the bedroom has an influence on easier sleep, on maintenance of sleep and on a quality of sleep perceived by the user during waking up.The subject matter of the present invention can also have one or more of the following features, individually or in combination.In some embodiments, the at least one operating parameter is configured to be controlled depending on at least one sleep phase of the user.Human sleep consists of a sequence of cycles. In an adult, the number of cycles is between 4 and 6, each cycle taking about 1.5 hours and consisting in turn of three phases:a light sleep phase that can be divided into a subphase of very light sleep and a subphase of light sleep; the light sleep phase is a sleepiness phase,a deep sleep phase, the most recoverable sleep phase,an REM sleep phase, the phase in which trauma occurs.The operating parameter is thus controlled directly depending on the sleep phase of the user in order to improve his sleep.A determination of the sleep phase in which the user is located can be made on the basis of an analysis of the generated brain signals or on the basis of the analysis of physical and / or physiological signals such as heart beat, breathing rate and movement.Namely, each phase is characterized by its own physical and / or physiological phenomena: [Tab 1] [Tab 1]Light sleepDecelerationStabilizationDecrease: DecreaseDeep Sleep Deep SleepMaximum DecreaseMaximum DecreaseAt standstill, standstill is stoppedREM SleepIrregularly irregularIrregularly irregularMuscle Atonia with Short TwitchesAccording to the invention, at least one operating parameter of the device is designed to be controlled as a function of at least one sleep phase of the user. In other words, the device adapts to the sleep and, in particular, to the sleep phase of the user in order to improve his sleep.In some embodiments, the control unit comprises a determination unit configured to determine the at least one sleep phase of the user depending on at least one indication regarding a physical and / or physiological activity.The determination unit thus links the at least one indication with respect to the physical and / or physiological activity in order to determine the sleep phase in which the user is located.According to one feature, the determination unit is part of the control unit.In some embodiments, the at least one indication regarding the physical and / or physiological activity corresponds to the at least one sleep phase of the user.In this embodiment, the device directly receives information about the sleep phase of the user.In some embodiments, the at least one indication regarding the physical and / or physiological activity of the user is transmitted to the air treatment device using a contactless technique.The air conditioning device may retrieve the at least one indication regarding the physical and / or physiological activity of the user in real time.The air treatment device may retrieve the at least one indication regarding the physical and / or physiological activity of the user, for example, by means of a contactless technique, which may be selected from: Bluetooth, Wi-Fi, Li-Fi, infrared and radio frequency, for example NFC.In some embodiments, the at least one operating parameter enables changing at least one treatment air flow rate and / or a noise level of the device and / or an air treatment.The treatment air flow rate corresponds to the air flow rate flowing through the treatment unit.The noise level is the noise level of the conditioning apparatus when the air conditioning unit is switched on. The apparatus includes a mode in which the noise level is less than 30 dB.Air treatment can be filtering and / or disinfection of air.According to one feature, during the light sleep phase, a noise level is reduced to a minimum or set to zero.In one feature, during the deep sleep and REM phases, the device maintains the quality of the room air by operating at a speed consistent with sleep.In some embodiments, the at least one operating parameter is controlled as a function of an anticipated sleep time and / or an anticipated wake-up time.The anticipated sleep time corresponds to a time at which the user schedules or is accustomed to sleep.The anticipated wake-up time corresponds to a time at which the user is scheduled or accustomed to wake-up.The processing device according to the invention thus takes into account a sleep routine of the user with the anticipated sleep time and / or the anticipated wake-up time. The conditioning device can therefore prepare the bedroom for the user's sleep and / or for waking up.According to one feature, the device carries out a processing of the room air as a function of the anticipated sleep time and / or the anticipated wake-up time and, for example, temporally before the anticipated sleep time and / or the anticipated wake-up time.In some embodiments, the anticipated sleep time and / or the anticipated wake-up time is determined depending on at least one indication regarding the user's physical and / or physiological activity detected on a previous day.The air treatment device can capture the at least one indication with respect to the physical and / or physiological activity of the user in the course of at least one day and derive the sleep routine of the user from this by means of an algorithm or by artificial intelligence in the course of the day and thus predict the anticipated sleep time and / or the anticipated wake-up time for the current day.A "previous day" is understood to mean a day that is in the past with respect to the current day.In some embodiments, the anticipated sleep time and / or anticipated wake-up time is indicated by the user at a human-machine interface of the device.In some embodiments, the conditioning unit includes an aroma therapy module and / or an air humidifier module.The flavor therapy module adds at least one aromatic plant compound, usually in the form of an essential oil, to the processing air to promote comfort and sleep of the user.The humidifier module has the function of changing a water content of the treatment air.Advantageously, the humidifier module comprises a water treatment module to prevent bacteria from propagating.
