Description

Title of the invention: Air treatment device controlled according to data relating to a user's physical and / or physiological activity technical field

[0001] The invention relates to the field of air treatment devices and more particularly to such a device, a system comprising such a device and at least one sleep measurement sensor, and a method for controlling such a device. Prior art

[0002] There are air treatment devices which aim to improve, or at least maintain, a user's sleep.

[0003] In order to allow these devices to operate before and during the user's sleep, they have a so-called 'night' operating mode in which certain operating characteristics are adapted for use in a bedroom. For example, the operating characteristics include the noise level of the device in operation, the dimensions of the device, filters, and light emitted by the device. Description of the invention

[0004] The invention aims to improve a user's sleep by means of an air treatment device. More specifically, the device according to the invention allows the device's operation to be adapted according to the user's sleep phases in order to facilitate falling asleep, maintaining sleep, or preparing for waking up.

[0005] One embodiment relates to an air treatment device, comprising at least one air treatment unit and one control unit, said device being configured to receive at least one data relating to a user's physical and / or physiological activity, and to control at least one operating parameter of at least one air treatment unit based on at least one data relating to the user's physical and / or physiological activity.

[0006] The air treatment unit includes modules for performing treatment, that is, an action on the air in a room. The treatment unit may include a filtration module comprising a filter configured to filter the air, or a disinfection module comprising a UV-C lamp configured to disinfect the air.

[0007] The control unit may include, in particular, a controller configured to drive the processing unit. The controller may also perform processing of at least one piece of data relating to the user's physical and / or physiological activity.

[0008] Data relating to the user's physical activity corresponds to data relating to a movement of the user such as acceleration, speed, frequency, amplitude, etc.

[0009] Data relating to the physiological activity of the user corresponds to data relating to the user's body such as temperature, heart rate, respiratory rate, blood pressure, pulse, etc.

[0010] The device according to the invention receives said data relating to the user's physical and / or physiological activity and controls the air handling unit based on this data. More specifically, the air handling unit modifies at least one operating parameter of the air handling unit.

[0011] Thus, the air treatment device adapts its operation, at least in real time, to the user's state. Indeed, it has been shown that the indoor air quality of the bedroom influences the ease of falling asleep, the maintenance of sleep, and the quality of sleep perceived by the user upon waking.

[0012] The object of this presentation may also have one or more of the following characteristics taken alone or in combination.

[0013] In some embodiments, at least one operating parameter is configured to be controlled according to at least one sleep phase of the user.

[0014] A person's sleep is a succession of cycles. In an adult, the number of cycles is between 4 and 6. Each cycle lasts approximately 1 hour and 30 minutes and is itself composed of 3 phases: - a phase of light sleep which can be divided into a sub-phase of very light sleep and a sub-phase of light sleep. The light sleep phase is a phase of drowsiness. - a phase of deep sleep. The most restorative phase of sleep. - a REM sleep phase. The phase during which the dreams.

[0015] The operating parameter is therefore directly controlled according to the user's sleep phase in order to improve the user's sleep.

[0016] A determination of the sleep phase in which the user is located can be made from an analysis of the brain signals produced, or from the analysis of physical and / or physiological signals such as heart rate, respiratory rate and movement.

[0017] Indeed, each phase is characterized by physical and / or physiological manifestations logics specific to it:

[0018] [Tab 1] Sleep phase Heart rate Respiratory rate Movements Light sleep Slowing down Stabilization Decrease Deep sleep Maximum decrease Maximum decrease Stop REM sleep Irregular Irregular Muscle atonia with some brief twitches

[0019] According to the invention, at least one operating parameter of the device is configured to be controlled according to at least one sleep phase of the user. In other words, the device adapts to sleep, and more particularly to the user's sleep phase, in order to improve the user's sleep.

[0020] In some embodiments, the control unit includes a determination unit configured to determine at least one sleep phase of the user based on at least one data point relating to physical and / or physiological activity.

[0021] The unit of determination therefore combines at least one data relating to a physical and / or physiological activity so as to determine the sleep phase in which the user is.

[0022] According to one characteristic, the determination unit is part of the control unit.

[0023] In some embodiments, at least one piece of data relating to a physical and / or physiological activity corresponds to at least one sleep phase of the user.

[0024] In this embodiment, the device directly receives information concerning the user's sleep phase.

[0025] In certain embodiments, at least one piece of data relating to the user's physical and / or physiological activity is transmitted to the air treatment device by means of a contactless technology.

[0026] The air treatment device can retrieve in real time at least one data relating to the physical and / or physiological activity of the user.

[0027] The air treatment device can retrieve at least one data relating to the user's physical and / or physiological activity, for example via a contactless technology which can be chosen from: Bluetooth, wifi, lifi, infrared and radio frequency, for example NFC.

[0028] In some embodiments, at least one operating parameter allows modification of at least one treated air flow rate, and / or a sound level of the device, and / or an air treatment.

[0029] The treated air flow rate corresponds to the air flow rate passing through the treatment unit.

[0030] The sound level is the sound level of the treatment device when the air handling unit is switched on. The device includes a mode in which the sound level is less than 30dB.

[0031] Air treatment can be air filtration and / or disinfection.

[0032] According to one characteristic, during the light sleep phase, a sound level is reduced to a minimum, or even to zero.

[0033] According to one feature, during the deep and paradoxical sleep phases, the device maintains indoor air quality by operating at a sleep-compatible rate.

[0034] In some embodiments, at least one operating parameter is controlled according to a predicted sleep time and / or a predicted wake-up time.

[0035] The predicted sleep time corresponds to a time at which the user plans or usually goes to bed.

[0036] The planned wake-up time corresponds to a time at which the user plans or usually wakes up.

[0037] The treatment device according to the invention thus takes into account the user's sleep routine through the predicted sleep onset time and / or the predicted wake-up time. The treatment device can therefore prepare the bedroom for the user's sleep and / or for waking up.

[0038] According to one feature, the device performs indoor air treatment according to the predicted sleep time and / or the predicted wake-up time, and for example in advance of the predicted sleep time and / or the predicted wake-up time.

[0039] In some embodiments, the predicted sleep time and / or predicted wake-up time is determined based on at least one piece of data relating to the user's physical and / or physiological activity recorded on a previous day.

[0040] The air treatment device can record at least one piece of data relating to the user's physical and / or physiological activity during at least one day prior to the date and deduce from this, by an algorithm or by artificial intelligence, the user's sleep routine during the previous day and thus predict, for the current day, the predicted time of falling asleep and / or the predicted time of waking up.

[0041] A previous day is understood to be a day that has passed in relation to the current day.

[0042] In some embodiments, the predicted sleep time and / or predicted wake-up time is indicated by the user on a Human-Machine interface of the device.

[0043] In some embodiments, the treatment unit includes an aromatherapy module and / or a humidifier module.

[0044] The aromatherapy module adds at least one aromatic plant compound to the treated air, most often in the form of an essential oil, so as to promote calmness and sleep for the user.

[0045] The humidifying module has the function of modifying the water content of the treated air.

[0046] Advantageously, the humidifier module includes a water treatment module to prevent bacterial growth. For example, the water treatment module may include a UV-C lamp.

[0047] In some embodiments, the device includes a light unit configured to be controlled according to at least one data relating to the physical and / or physiological activity of the user.

[0048] In some embodiments, the light unit is controlled according to at least one sleep phase of the user.

[0049] The light unit provides illumination for the room in which the air treatment device is located. The light unit therefore adapts its operation to the user's sleep patterns. For example, the device can gradually decrease the brightness before the anticipated bedtime and / or gradually increase the brightness at the anticipated wake-up time.

[0050] According to one feature, during the light sleep phase, the light level of the device is reduced to a minimum, or even to zero.

[0051] In some embodiments, the device includes a global control unit configured to transmit a command order to another device in a network of connected objects.

[0052] The network of connected objects may include, but is not limited to: a connected light bulb, a temperature control thermostat, a humidity management device, a ventilation system.

[0053] The global control unit determines a command order which is sent to another device in the network of connected objects.

[0054] In some embodiments, the command order depends on at least one piece of data relating to a physical and / or physiological activity and / or the predicted time of falling asleep and / or the predicted time of waking up and / or a sleep phase of the user.

[0055] The command command allows modification of the operation of at least one of the devices positive aspects of the network of connected objects so as to adapt its operation to a sleep phase of the user and therefore to improve the latter's sleep.

[0056] The invention also relates to an air treatment system comprising an air treatment device according to the invention and at least one sleep measurement sensor configured to acquire at least one data relating to the user's physical and / or physiological activity.

[0057] According to the invention, the air treatment device receives at least one data relating to the physical and / or physiological activity of the user from at least one sleep measurement sensor.

[0058] The sleep measurement sensor can be a sensor in contact with the user. The sensor can be worn by the user, for example, as a bracelet or a watch.

[0059] The sleep measurement sensor can be a non-contact sensor. For example, the sensor can be placed under the mattress. In this case, it is a sensor operating on the principle of ballistocardiography. The sensor can also be a sensor operating on radar or sonar technology.

[0060] The sensor can deliver information on the user's sleep phase, and / or on movement (acceleration, speed, frequency, amplitude, etc.) and / or temperature, heart rate, respiratory rate, blood pressure, pulse, etc.

[0061] The sensor may include an accelerometer.

[0062] In some embodiments, at least one sleep measurement sensor is arranged so that it can be mechanically coupled to the device, and mechanically uncoupled from the device.

[0063] The sleep measurement sensor is detachable from the device.

[0064] The sleep measurement sensor is coupled to the device by a fastening means which can be chosen from: a magnet, a housing, and a clip.

[0065] Thus, the sleep measurement sensor can be positioned on the user's bedside table at the time of the user's bedtime.

[0066] Another aspect of the invention relates to a method for controlling an air treatment device comprising: - A step of receiving at least one piece of data relating to the user's physical and / or physiological activity; - A control step of at least one operating parameter of the air treatment unit based on at least one data relating to the physical and / or physiological activity of the user.

[0067] The invention will be better understood, from the following description, which relates to a embodiment according to the present invention, given by way of non-limiting example and explained with reference to the accompanying schematic drawings, in which:

[0068] [Fig-1] is a schematic representation of a chronogram of a user's sleep phases as a function of time;

[0069] [Fig.2] is a representation of a first embodiment of an air treatment device according to the invention;

[0070] [Fig.3] is a representation of a second embodiment of an air treatment device according to the invention; Description of the implementation methods

[0071] Only the elements necessary for understanding the invention have been shown. To facilitate reading the drawings, the same elements bear the same reference numerals from one figure to another.

[0072] Figures 2 and 3 represent two embodiments of an air treatment system 1, 1', comprising an air treatment device 10, 10' and at least one sleep measurement sensor 20, 20'.

[0073] Each embodiment of the air treatment system 1, 1' includes an air treatment device 10, 10' which is equipped with an air treatment unit and a control unit 11, 11'.

[0074] The control unit 11, 11' may include in particular a controller configured to control the air handling unit.

[0075] The air treatment unit includes modules for performing treatment, that is, an action on the air in a room. The treatment unit may include a filtration module comprising a filter configured to filter the air, and / or a disinfection module comprising a UV lamp configured to disinfect the air.

[0076] In some embodiments, the treatment unit includes an aromatherapy module and / or a humidifier module.

[0077] The aromatherapy module adds to the treated air at least one aromatic plant compound, most often in the form of an essential oil, so as to promote calmness and sleep for a user of the air treatment system 1, 1'.

[0078] The humidification module functions to modify the moisture content of the treated air. Advantageously, the humidification module includes a water treatment module to prevent bacterial growth. For example, the water treatment module may include a UV-C lamp.

[0079] In certain embodiments, the air treatment device 10, 10' includes a light unit. The light unit provides illumination for the room in which the air treatment device is located. The light unit adapts its operation while the user is asleep.

[0080] According to the invention, the air treatment device 10, 10' receives at least one piece of data relating to the user's physical and / or physiological activity. For example, and as shown in [Fig. 2] and 3, at least one piece of data relating to the user's physical and / or physiological activity may be emitted by at least one sleep measurement sensor 20, 20'.

[0081] According to the embodiment shown in [Fig. 2], the sleep measurement sensor 20 is a sensor in contact with the user. The sleep measurement sensor 20 can be worn by the user, for example, as a bracelet or a watch. The sleep measurement sensor 20 may include an accelerometer.

[0082] However, the sleep measurement sensor could also be placed near the user, on a bedside table for example or in the bedroom in the direction of the sleeper.

[0083] According to the embodiment shown in [Fig. 3], the sleep measurement sensor 20' is a non-contact sensor. The sleep measurement sensor 20' can, for example, be a sensor operating on radar or sonar technology. In the embodiment of [Fig. 3], the sleep measurement sensor 20' is arranged so that it can be mechanically coupled to, and mechanically uncoupled from, the air treatment device 10'. The sleep measurement sensor 20' is therefore detachable from the device 10'. The sleep measurement sensor 20' is coupled to the device by a fastening means that can be selected from: a magnet, a housing, and a clip.

[0084] The sleep measurement sensor 20, 20' delivers at least one data relating to a user's physical and / or physiological activity to the air treatment device 10, 10'.

[0085] Data relating to the user's physical activity corresponds to data relating to a movement of the user such as acceleration, speed, frequency, amplitude, etc.

[0086] Data relating to the physiological activity of the user corresponds to data relating to the user's body such as temperature, heart rate, respiratory rate, blood pressure, pulse, etc.

[0087] In the embodiments illustrated in Figures 2 and 3, at least one piece of data relating to the user's physical and / or physiological activity is transmitted to the air treatment device 10, 10' by means of a contactless technology.

[0088] The air treatment device 10, 10' can retrieve in real time at least one data relating to the physical and / or physiological activity of the user.

[0089] The air treatment device 10, 10' can retrieve at least one piece of data relating to the user's physical and / or physiological activity, for example via a contactless technology that can be chosen from: Bluetooth, wifi, lifi, infrared and radio frequency, for example NFC.

[0090] According to one embodiment, at least one operating parameter is configured to be controlled according to at least one sleep phase of the user.

[0091] A person's sleep is a succession of cycles as illustrated in [Fig. 1]. In an adult, the number of cycles is between 4 and 6. Each cycle lasts approximately 1 hour 30 minutes and is itself composed of 3 phases: - a light sleep phase Si which can be divided into a very light sleep subphase and a light sleep subphase. The light sleep phase Si is a phase of drowsiness. - a phase of deep sleep (Sp). This is the most restorative sleep phase. - a REM sleep phase (Pp). The phase during which dreams occur.

[0092] The operating parameter is therefore directly controlled according to the sleep phase Si, Sp, Pp of the user in order to improve the latter's sleep.

[0093] A determination of the sleep phase Si, Sp, Pp in which the user is can be carried out from an analysis of the brain signals produced, or from the analysis of physical and / or physiological signals such as heart rate, respiratory rate and movement.

[0094] According to the invention, at least one operating parameter of the device 10, 10' is configured to be controlled according to at least one sleep phase Si, Sp, Pp of the user. In other words, the device 10, 10' adapts to sleep, and more particularly to the sleep phase Si, Sp, Pp of the user in order to improve the user's sleep.

[0095] According to one embodiment, the control unit includes a determination unit configured to determine at least one sleep phase Si, Sp, Pp of the user based on at least one data relating to physical and / or physiological activity.

[0096] The unit of determination therefore combines at least one data relating to a physical and / or physiological activity so as to determine the sleep phase Si, Sp, Pp in which the user is.

[0097] According to one characteristic, the determination unit is part of the control unit.

[0098] In certain embodiments, at least one piece of data relating to physical and / or physiological activity corresponds to at least one sleep phase of the user. In this embodiment, the device 10, 10' directly receives information concerning the sleep phase Sb Sp, Pp of the user.

[0099] The air treatment device 10, 10' can therefore directly receive information concerning the sleep phase Sb Sp, Pp of the user and / or determine from at least one data relating to the physical and / or physiological activity of the user the sleep phase Sb Sp, Pp in which the user is.

[0100] The air treatment device 10, 10' is configured to receive at least one data relating to a user's physical and / or physiological activity, and to control at least one operating parameter of at least one air treatment unit based on at least one data relating to the user's physical and / or physiological activity.

[0101] At least one operating parameter allows modification of at least one treated air flow rate, and / or a noise level of the device, and / or an air treatment.

[0102] The treated air flow rate corresponds to the air flow rate passing through the treatment unit.

[0103] The sound level is the sound level of the treatment device when the air handling unit is switched on. The device includes a mode in which the sound level is less than 30dB.

[0104] Air treatment may be air filtration and / or disinfection and / or aromatherapy treatment and / or treatment related to air humidity.

[0105] In some embodiments, at least one operating parameter is controlled according to a predicted sleep time and / or a predicted wake-up time.

[0106] The predicted sleep time corresponds to a time at which the user plans or usually goes to bed.

[0107] The planned wake-up time corresponds to a time at which the user plans or usually wakes up.

[0108] The treatment device 10, 10' according to the invention thus takes into account the user's sleep routine through the predicted bedtime and / or the predicted wake-up time. The treatment device 10, 10' can therefore prepare the bedroom for the user's bedtime C, and / or for waking up R.

[0109] In some embodiments, the predicted sleep onset time and / or predicted wake-up time is determined based on at least one piece of data relating to the user's physical and / or physiological activity recorded on a previous day.

[0110] The air treatment device 10, 10' can record, during at least one day preceding the use, at least one piece of data relating to the user's physical and / or physiological activity and deduce from this, by an algorithm or by artificial intelligence, the the user's sleep routine during the previous day and therefore predict, for the current day, the predicted sleep time and / or the predicted wake-up time.

[0111] In some embodiments, the predicted sleep time and / or predicted wake-up time is indicated by the user on a Human-Machine interface of the device.

[0112] The light unit is configured to be controlled according to at least one data relating to the user's physical and / or physiological activity.

[0113] For example, the air treatment device 10, 10' can gradually decrease the brightness before the predicted sleep time and / or gradually increase the brightness at the predicted wake-up time.

[0114] In some embodiments, the device 10, 10' includes a global control unit configured to transmit a command order to another device in a network of connected objects.

[0115] The network of connected objects may include, but is not limited to: a connected light bulb, a temperature control thermostat, a humidity management device, a ventilation system.

[0116] The global control unit determines a command order which is sent to another device in the network of connected objects.

[0117] In some embodiments, the command order depends on at least one data relating to a physical and / or physiological activity and / or the predicted time of falling asleep and / or the predicted time of waking up and / or a sleep phase Sb Sp, Pp of the user.

[0118] The command order allows the operation of at least one of the devices in the network of connected objects to be modified so as to adapt its operation to a sleep phase Sb Sp, Pp of the user and thus to improve the sleep of the latter.

[0119] The invention aims to improve a user's sleep by means of the air treatment device 10, 10'. More specifically, the device 10, 10' according to the invention makes it possible to adapt the operation of the device 10, 10' according to the user's sleep phases Sb Sp, Pp in order to facilitate falling asleep after bedtime C, maintaining sleep or preparing for waking up R. Indeed, it has been shown that the quality of indoor air in the bedroom has an influence on the ease of falling asleep, on maintaining sleep and on the quality of sleep perceived by the user upon waking.

[0120] Another aspect of the invention relates to a method for controlling an air treatment device 10, 10' comprising: - A step involving the reception of at least one piece of data relating to physical activity and / or physiological characteristics of the user; - A control step of at least one operating parameter of the air treatment unit based on at least one data relating to the physical and / or physiological activity of the user.

[0121] Figure 1 illustrates a chronogram of a user's sleep phases Sb Sp, Pp as a function of time. For each sleep phase, light SI, deep Sp or REM Pp, the air treatment device 10, 10' has a specific operating mode.

[0122] More specifically, before bedtime C, the device 10, 10' carried out air treatment and sent control commands to various devices in the network of connected objects so that the temperature of the room was between 16°C and 18°C, and that the CO2 level was less than 800ppm.

[0123] During the light sleep phase SI, during which waking is easy, the air treatment device 10, 10', has a so-called light operation in which the sound level must not exceed 30 dB, or even zero, and the brightness is reduced to the maximum, or even completely turned off.

[0124] Then during the deep sleep phase Sp and paradoxical sleep phase Pp, during which waking is difficult, the air treatment device 10, 10', has an intense operation Fl in which it maintains the quality of the indoor air by operating at a rate compatible with its sleep phases.

[0125] Although the present invention has been described with reference to specific embodiments, it is evident that modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. In particular, individual features of the various embodiments illustrated / mentioned can be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than a restrictive sense.

[0126] It is also evident that all the characteristics described with reference to a process are transposable, alone or in combination, to a device, and conversely, all the characteristics described with reference to a device are transposable, alone or in combination, to a process.
