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. State of the prior art

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

[0003] In order to enable these devices to operate before and during the user's sleep, they have a so-called 'night' operating mode in which operating characteristics are adapted for use in a bedroom. For example, the operating characteristics are a sound level of the device in operation, dimensions of the device, filters, and light diffused by the device. Statement 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 makes it possible to adapt the operation of the device according to the user's sleep phases to facilitate falling asleep, maintain sleep or prepare for waking up.

[0005] One embodiment relates to an air treatment device, comprising at least one air treatment unit and a control unit, said device being configured to receive at least one piece of data relating to 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 as a function of the at least one piece of data relating to the physical and / or physiological activity of the user.

[0006] The air treatment unit comprises modules for performing a treatment, i.e. an action on the air in a room. The treatment unit may comprise 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 control 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 physical activity of the user corresponds to data relating to a movement of the user such as an acceleration, a speed, a frequency, an 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 physical and / or physiological activity of the user and controls the air treatment unit as a function of this data. More particularly, the treatment unit modifies the at least one operating parameter of the air treatment unit.

[0011] Thus, the air treatment device adapts its operation, at least in real time, to a state of the user. Indeed, it has been demonstrated that the quality of the air inside 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.

[0012] The subject matter of the present disclosure may also have one or more of the following characteristics taken alone or in combination.

[0013] In some embodiments, the at least one operating parameter is configured to be controlled based on 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 1h30 and is itself composed of 3 phases: - a light sleep phase that can be divided into a very light sleep sub-phase and a light sleep sub-phase. The light sleep phase is a phase of drowsiness. - a deep sleep phase. The most restorative sleep phase. - a phase of REM sleep. The phase during which the dreams.

[0015] The operating parameter is therefore directly controlled according to the user's sleep phase so as to improve the latter'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 Breathing rate Movements Light sleep Slowing Stabilization Decline Deep sleep Maximum decrease Maximum decrease Stop REM sleep Irregular Irregular Muscle atony with some brief jerks

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

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

[0021] The determination unit therefore combines at least one piece of 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 certain embodiments, the at least one piece of data relating to a physical and / or physiological activity corresponds to at least one phase of the user's sleep.

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

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

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

[0027] The air treatment device can recover at least one piece of data relating to the physical and / or physiological activity of the user, for example via a contactless technology which can be chosen from: Bluetooth, Wi-Fi, Li-Fi, infrared and radio frequency, for example NFC.

[0028] In certain embodiments, the at least one operating parameter makes it possible to modify at least one flow rate of treated air, 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 treatment unit is in operation. The device includes a mode in which the sound level is less than 30dB.

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

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

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

[0034] In some embodiments, the at least one operating parameter is controlled based on a predicted sleep onset schedule and / or a predicted wake-up schedule.

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

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

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

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

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

[0040] The air treatment device can record, over the course of at least one previous day, at least one item of data relating to the physical and / or physiological activity of the user and deduce therefrom by an algorithm, or by artificial intelligence, the sleep routine of the user over the course of the previous day and therefore predict, for the current day, the predicted sleep onset time and / or the predicted wake-up time.

[0041] A previous day means a day past the current day.

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

[0043] In some embodiments, the treatment unit comprises 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 calming and sleep for the user.

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

[0046] Advantageously, the humidifier module comprises a water treatment module to prevent bacterial proliferation. For example, the water treatment module may comprise a UV-C lamp.

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

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

[0049] The light unit allows lighting of the room in which the air treatment device is placed. The light unit therefore adapts its operation to the user's sleep. For example, the device can gradually decrease the brightness before the expected sleep time and / or gradually increase the brightness at the expected wake-up time.

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

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

[0052] The network of connected objects may include, in a non-limiting manner: a connected light bulb, a temperature regulation thermostat, a humidity management device, a ventilation system.

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

[0054] In certain embodiments, the control order depends on at least one piece of data relating to a physical and / or physiological activity and / or the predicted sleep time and / or the predicted wake-up time and / or a sleep phase of the user.

[0055] The control order makes it possible to modify the operation of at least one of the devices positive effects of the connected object network so as to adapt its operation to a user's sleep phase and therefore 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 piece of data relating to the physical and / or physiological activity of the user.

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

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

[0059] The sleep measurement sensor may be a sensor without contact with the user. The sensor may for example be placed under the mattress. It is then a sensor operating on a ballistocardiography principle. The sensor may 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 a movement (an acceleration, a speed, a frequency, an amplitude, etc.) and / or a temperature, a heart rate, a respiratory rate, a blood pressure, a pulse, etc.

[0061] The sensor may comprise an accelerometer.

[0062] In some embodiments, the at least one sleep measurement sensor is arranged to 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 fixing means which can be chosen from: a magnet, a housing, and a clip.

[0065] Thus, the sleep measurement sensor can be positioned on a user's bedside table when the user goes to bed.

[0066] Another aspect of the invention relates to a method of controlling an air treatment device comprising: - A step of receiving at least one piece of data relating to the physical and / or physiological activity of the user; - A step of controlling at least one operating parameter of the air treatment unit as a function of at least one piece of data relating to the physical and / or physiological activity of the user. Brief description of the drawings

[0067] The invention will be better understood, thanks to 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 appended 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 embodiments

[0071] Only the elements necessary for understanding the invention have been shown. To facilitate reading of the drawings, the same elements bear the same references 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' comprises an air treatment device 10, 10' which is provided with an air treatment unit and a control unit 11, 11'.

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

[0075] The air treatment unit comprises modules for performing a treatment, i.e. an action on the air in a room. The treatment unit may comprise 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 processing unit comprises an aromatherapy module and / or a humidifier module.

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

[0078] The humidifier module has the function of modifying a water content of the treated air. Advantageously, the humidifier module comprises a water treatment module to prevent a proliferation of bacteria. For example, the water treatment module may comprise a UV-C lamp.

[0079] In some embodiments, the air treatment device 10, 10' comprises a light unit. The light unit provides illumination of the room in which the air treatment device is placed. 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 physical and / or physiological activity of the user. For example, and as shown in [Fig.2] and 3, the at least one piece of data relating to the physical and / or physiological activity of the user can 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 a bracelet or a watch. The sleep measurement sensor 20 can comprise an accelerometer.

[0082] Nevertheless, the sleep measurement sensor could also be placed close to 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 sensor without contact with the user. The sleep measurement sensor 20' may for example be a sensor operating on radar or sonar technology. In the embodiment of [Fig. 3], the sleep measurement sensor 20' is arranged to be able to be mechanically coupled to the device, 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 fixing means which may be chosen from: a magnet, a housing, and a clip.

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

[0085] Data relating to the physical activity of the user 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, the at least one piece of data relating to the physical and / or physiological activity of the user is transmitted to the air treatment device 10, 10' by means of contactless technology.

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

[0089] The air treatment device 10, 10' can recover at least one piece of data relating to the physical and / or physiological activity of the user, for example via a contactless technology which can be chosen from: Bluetooth, Wi-Fi, Li-Fi, infrared and radio frequency, for example NFC.

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

[0091] A person's sleep is a succession of cycles as illustrated in [Fig.l]. In an adult, the number of cycles is between 4 and 6. Each cycle lasts approximately 1h30 and is itself composed of 3 phases: - a light sleep phase If which can be divided into a very light sleep sub-phase and a light sleep sub-phase. The light sleep phase If is a phase of drowsiness. - a deep sleep phase Sp. This is the most restorative sleep phase. - a phase of REM sleep Pp. The phase during which dreams occur.

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

[0093] A determination of the sleep phase Si, Sp, Pp in which the user is in 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, the at least one operating parameter of the device 10, 10' is configured to be controlled as a function of 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 latter's sleep.

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

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

[0100] The air treatment device 10, 10' is configured to receive at least one piece of data relating to 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 as a function of the at least one piece of data relating to the physical and / or physiological activity of the user.

[0101] The at least one operating parameter makes it possible to modify at least one flow rate of treated air, and / or a sound level of the device, and / or an air treatment.

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

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

[0104] An air treatment may be an air filtration and / or disinfection and / or an aromatherapy treatment and / or an air humidity treatment.

[0105] In some embodiments, the at least one operating parameter is controlled based on a predicted sleep onset schedule and / or a predicted wake-up schedule.

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

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

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

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

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

[0111] In some embodiments, the predicted sleep time and / or the 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 piece of data relating to the physical and / or physiological activity of the user.

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

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

[0115] The network of connected objects may include, in a non-limiting manner: a connected light bulb, a temperature regulation thermostat, a humidity management device, a ventilation system.

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

[0117] In certain embodiments, the control order depends on at least one piece of data relating to a physical and / or physiological activity and / or the predicted sleep time and / or the predicted wake-up time and / or a sleep phase Sb Sp, Pp of the user.

[0118] The control order makes it possible to modify the operation of at least one of the devices of the network of connected objects so as to adapt its operation to a sleep phase Sb Sp, Pp of the user and therefore to improve the latter's sleep.

[0119] The invention aims to improve the sleep of a user by means of the air treatment device 10, 10'. More precisely, the device 10, 10' according to the invention makes it possible to adapt an operation of the device 10, 10' according to the sleep phases Sb Sp, Pp of the user to facilitate falling asleep after going to bed C, maintain sleep or prepare for waking up R. Indeed, it has been demonstrated that the quality of the air inside 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 up.

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

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

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

[0123] During the light sleep phase SI, during which waking up 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 switched off.

[0124] Then during the deep sleep phase Sp and paradoxical Pp, during which waking up is difficult, the air treatment device 10, 10', has a so-called intense operation Fl in which it maintains the quality of the interior 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 obvious that modifications and changes may 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 illustrated / mentioned embodiments may be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than restrictive sense.

[0126] It is also obvious that all the characteristics described with reference to a method 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 method.
