Modular fan assembly with articulating nozzle

Abstract

An air treatment system is disclosed that includes a modular configuration whereby a fan module, filter module, and humidifier module may couple together to provide a plurality of air treatment solutions. In more detail, the modules can stack end-to-end in a vertical configuration. The modules may electrically couple to each other via a common electrical bus and enable a controller disposed in the fan module (or other module) to control fan flow rates, direction, and humidity. The fan module can include an articulating nozzle capable of directing airflow in virtually any direction and angle about an environment. The fan module can further include an inlet arrangement that can selectively restrict external air from entering the fan module housing when the fan module is fluidly coupled to the filter module. Thus, the fan module may generate air flow from exclusively filtered air to minimize or otherwise reduce bacterial/mold growth within the fan module housing.

Description

TECHNICAL FIELD

This specification relates generally to air treatment systems, and more particularly, to a modular fan assembly with an articulating nozzle and a modular housing arrangement whereby air treatment assemblies such as the articulating nozzle, humidifier, and air filter may be coupled together to form a stack/tower arrangement to provide multiple air quality treatment solutions within a relatively compact footprint.

BACKGROUND INFORMATION

Fan assemblies generate air flow in various environments such as homes and offices. Fans often include a mechanism that allows a user to redirect air output in a desired location by applying a user-supplied force to rotate/tilt the fan to a desired position. Also, fans often include a feature that allows the fan to horizontally span/sweep right-to-left automatically to target a larger area within a given environment.

Some fan assemblies offer integrated humidification devices which may include a water reservoir proximate to a fan/impeller of the fan assembly. Moisture may then be introduced by exposing the impeller to water droplets/vapor. However, exposure of the impeller and other internal workings of the fan to water vapor/droplets may promote the growth of bacteria/mold. As a result, the fan may then output foul smelling and/or air which is harmful to occupants in the environment. Therefore, while known fan apparatuses are generally effective at increasing air circulation, such fans remain at a fixed position and are unable to adjust to varying conditions in the environment. Moreover, fans may inadvertently circulate air which includes harmful bacterial and/or foul-smelling particles.

DETAILED DESCRIPTION

As discussed above, fan devices may inadvertently circulate air which includes harmful bacteria and/or foul-smelling particles. Moreover, such fan devices can encourage the internal growth of bacteria and mold on components such as a motor that is used to generate airflow. This can foul both the air quality of an environment, and shorten the overall lifespan of components within the fan device.

In general, the present disclosure is directed to an air treatment system that includes a modular configuration whereby a fan module, filter module, and humidifier module may couple together to provide a plurality of air treatment solutions within a relatively small footprint. In more detail, the fan module, filter module and humidifier module can stack end-to-end in a vertical configuration. The modules may electrically couple to each other via a common electrical bus and enable a controller disposed in the fan module (or other module) to control fan flow rates, direction, and humidity. Note the modules may be configured to operate independent of each other (e.g., when decoupled and separated). The fan module may include an articulating nozzle capable of directing airflow in virtually any direction and angle about an environment. The fan module can further include an intake with an inlet arrangement that can selectively restrict external air from entering the fan module housing when the fan module is fluidly coupled to the filter module. Thus, the fan module may generate air flow from exclusively filtered air to minimize or otherwise reduce bacterial/mold growth within the fan module housing.

The term “coupled” as used herein refers to any connection, coupling, link or the like. Such “coupled” devices are not necessarily directly connected to one another and may be separated by intermediate components or devices.

The term substantially, as generally referred to herein, refers to a degree of precision within acceptable tolerance that accounts for and reflects minor real-world variation due to material composition, material defects, and/or limitations/peculiarities in manufacturing processes. Such variation may therefore be said to achieve largely, but not necessarily wholly, the stated characteristic. To provide one non-limiting numerical example to quantify “substantially,” minor variation may cause a deviation of up to and including ±5% from a provided quality/characteristic unless otherwise provided by the present disclosure.

Turning now to FIG. 1, one embodiment of an air treatment system 100 is shown in accordance with aspects of the present disclosure. As shown, the air treatment system 100 includes a fan 102 (or fan module 102) removably coupled to an optional air filter 120 (or air filter portion 120), and an optional humidifier 122 (or humidifier portion 122). Note that the optional air filter 120 and the optional humidifier 122 may be coupled in a different order, such as shown in FIGS. 13A-13D where the humidifier 122 is coupled between the filter 120 and the base 240 of the fan module 102. As shown and described, the components of the air treatment system may be coupled end-to-end to form a vertical stack configuration. In the stack configuration, the humidifier module 122 may support the fan module 102 and the filter module 120. The fan module 102, filter module 120 and humidifier 122 may also be referred to as a fan module 102, filter module 120 and humidifier module 122.

The fan module 102 may include a housing 110 formed of a single piece or may optionally comprise a plurality of housing portions. Each of the optional humidifier 122 and the air filter 120 may both electrically and fluidly couple with the fan module 102, although this disclosure is not limited in this regard. For example, and as discussed further below, the humidifier 122 may not necessarily be in direct fluid communication (e.g., via one or more passageways therebetween) and may instead be indirectly fluidly coupled by virtue of the humidifier outputting humidified air externally which may then be received by the fan module via, for instance, inlet ports 113-1 and 113-2. The humidifier 122 may include a plurality of fluid couplings, including air, water, emulsions of air and water, and purified air received from the air filter 120.

The fan module 102 includes a controller 104, a pan/tilt mechanism 106, a motor and fan assembly 108, and an air intake 112. The fan module 102 may also include an antenna device 116. The antenna device 116 (which may also be referred to as a network interface) may be configured to communicate with, for instance, one or more user devices such as the user device 118. The user device 118 may include a so-called “app” for controlling operation of the air treatment system 100, which will be discussed in greater detail below. The fan module 102 may therefore communicate with the user device 118 via a wireless connection 120.

To this end, air treatment system 100 may be configured for close range or long range communication between the fan module 102 and the user device 118. The term, “close range communication” is used herein to refer to systems and methods for wirelessly sending/receiving data signals between devices that are relatively close to one another. Close range communication includes, for example, communication between devices using a BLUETOOTH™ network, a personal area network (PAN), near field communication, ZigBee networks, a Wi-Fi network (e.g., IEE 802.11X) millimeter wave communication, ultra-high frequency (UHF) communication, combinations thereof, and the like. Close range communication may therefore be understood as enabling direct communication between devices, without the need for intervening hardware/systems such as routers, cell towers, internet service providers, and the like.

The controller 104 comprises at least one processing device/circuit such as, for example, a digital signal processor (DSP), a field-programmable gate array (FPGA), Reduced Instruction Set Computer (RISC) processor, x86 instruction set processor, microcontroller, an application-specific integrated circuit (ASIC). The controller 104 may be implemented, for example, using software (e.g., C or C++ executing on the controller/processor 104), hardware (e.g., hardcoded gate level logic or purpose-built silicon) or firmware (e.g., embedded routines executing on a microcontroller), or any combination thereof. The controller 104 may further include a memory 105. The memory 105 may comprise, for example, volatile and/or non-volatile memory. The memory 105 may include operational settings/parameters such as fans speed, heating/cool modes, aromatic selection properties, scheduling, voice recognition profiles, and/or face recognition profiles. Each of the operational settings may be adjusted remotely via the app executed on the user device 118, for instance. The memory 105 may also include air particle quality measurements, and fan schedules. The app may further allow for displaying of data logged from the fan module. Such logged data may include periodic temperature measurements, particle count data, and so on. Note, other modules (e.g., the filter module and the humidifier module) may also include associated controllers and/or memory that enable independent operation. However, the controller 104 may become a “master” controller when the modules are coupled together.

The pan/tilt mechanism 106 may comprise one or more mechanisms for horizontal and/or vertical adjustment of the portion of the housing 110 including the motor and fan 108. For instance, the pan/tilt mechanism 106 may be configured with one or more gears, servos, etc., to adjust the yaw/pitch based on user input (e.g., from the user device 118). Accordingly, the pan/tilt mechanism 106 allows the fan module 102 to adjust both along a horizontal and/or vertical axis to provide up to 360 degrees of motion for each axis thus forming a spherical coverage envelop.

The motor and fan 108 may output air 150 and may be any suitable motor and fan for providing a desired amount of air volume and air flow speed. The motor of the motor and fan 108 may be variable (e.g., a DC stepper motor, or a brushless DC motor) for adjusting fan speed during operation.

The intake 112 may include one or more ducts/passageways for providing air to the motor and fan 108. The intake 112 may include a plurality of intake ports including intake ports 113-1 and 113-2. Intake ports 113-1 and 113-2 may be configured to receive air 140 external to the housing 110. In some cases, the intake ports 113-1 and 113-2 may be disposed on opposite sides of the housing 110.

The intake 112 may further include intake ports 113-3 and 113-4. Intake ports 113-3 and 113-4 may be configured to receive air 142 from the filter 120. In such cases, the air 142 may be accurately referred to as filtered air. In an embodiment, the presence of the filter 120 coupled to the housing 110 causes the intake ports 113-1 and 113-2 to mechanically close. This may be accomplished via an internal damper, valve, closeable vents, or other suitable device. Alternatively, or in addition, the intake ports 113-1 and 113-2 may be closed simply by the presence of a portion of the filter 120 blocking air flow. Therefore, intake ports 113-1 and 113-2 may be entirely closed or at least substantially closed, e.g., restricting input from external air 140 to less than 10%, and preferably, substantially 0%. Thus, the fan module 102 may receive only filtered air 142 for output by the motor and fan 108 when the fan module 102 is coupled to the filter 120. This may advantageously reduce the amount of humidified air from a humidifier or from a surrounding environment that would otherwise enter the fan module 102 and encouraging bacteria and mold growth.

Continuing on, the filter 120 may include a housing 111. The housing 111 may include a portion configured to removably couple to the housing 110 of the fan module 102. The filter 120 may include, for instance, a HEPA filter for removing allergens, air droplets, dust and/or other contaminants in an environment. The filter 120 may include a removable filter portion for easy replacement.

The humidifier 122 may include a housing 113. The housing 113 may include a portion configured to removably couple to the housing 111 of the filter 120 and/or couple (e.g., directly) to the housing 110 of the fan module 102. The humidifier 122 may include one or more water reservoirs (not shown) and an assembly for dispersing water droplets/vapor into the air via air 144. The humidifier 122 may include circuitry (not shown) to output a desired amount of water vapor into an environment. In some cases, the humidifier 122 electrically couples via bus 146 to the controller 104. The humidifier 122 may receive signals from the controller 104 by way of the bus 146 to control the amount of water vapor output and the amount of time to output water vapor (e.g., based on a schedule). In an embodiment, relative humidity may be periodically measured and may be optionally displayed via an app on the user device 118 and/or on a display (not shown) provided by the housing 110. In response to humidity exceeding a predefined threshold, fan speed and/or the humidifier output may be adjusted to reach a target humidity (e.g., a user defined humidity level set via the app of the user device 118).

In some embodiments, and as shown, the humidifier 122 is not in fluid communication with the fan module 102. In this case, the humidified air 144 output by the humidifier 122 is external to the fan module 102. The humidified air 144 may then be received by the fan module 102 via intake ports 113-1 and 113-2 and/or intake ports 113-3 and 113-4 (in cases where the filter 120 is present). Thus, the growth of bacterial/mold on the motor and fan 108 may be eliminated as the fan simply receives filtered air rather than humidified air containing water droplets and/or air-borne contaminants which other integrated fan solutions utilize.

The fan module 102 may further include additional circuitry 114. Additional circuitry 114 may include, for example, one or more image sensors/cameras. One example image sensor 312 is shown in FIG. 3. For example, the one or more image sensors may output color image data (RGB), color and depth image data (RGBD camera), depth sensor information, stereo camera information (L/R RGB), YUV, infrared signals, and so on. For example, the additional circuitry 114 may include a first sensor being an infrared detector and a second sensor being a color-image sensor (e.g., RGB, YUV). In one example, the fan module 102 includes a first image sensor configured for capturing an image signal (e.g., color image sensor, depth-enabled image sensing (RGDB), stereo camera (L/R RGB), YUV, infrared, and x-ray) and a second image sensor configured to capture image data different from the first image sensor.

In an embodiment, the fan module 102 compares image data received from the one or more image sensors to data within memory 105 to, for example, recognize a particular user present in an environment. In this embodiment, the controller 104 may implement a known facial recognition algorithm to recognize a user. In the event a user is recognized, the fan module 102 may automatically begin output of air 150 based on a user profile. The user profile may include a preferred fan speed, a preferred fragrance preference, and/or whether the fan module 102 should output air 150 directly at a recognized user's position in a room or not, as the case may be.

Note that this disclosure is not necessarily limited to tracking only “identified” users. For instance, in some cases the fan module 102 may pan/tilt, e.g., via the pan/tile mechanism 106, to move to follow any person in an environment as they move around.

In an embodiment, the image data processed by the fan module 102 may also include thermal (e.g., infrared) image data, as discussed above. In this embodiment, the fan module 102 may thermally map a room to identify areas of interest for cooling/heating purposes. For instance, if warm air is found to be in pockets (e.g., the corner of a ceiling), the fan module 102 may identify the spot and direct air flow in that general direction to bring the temperature down.

The thermal map may also extend to people/pets in a room. For example, the heat signature of a user may be utilized to determine if the fan module 102 should direct air in that user's direction. In this example, a person who appears relatively hot (e.g., having just come indoors on a hot summers day) may cause the fan module 102 to register the heat signature as needing cooling, e.g., based on a predefined threshold temperature, and direct air accordingly. In some cases, the fan module 102 provides the thermal data to the user device 118, such as shown in FIG. 8. In this case, the user may utilize the visualized thermal image data 802 to “train” the app in order to cause the fan module 102 to provide heating/cooling depending on a person's registered heat signature. The thermal image data sent to the user device 118 may also allow a user to recognize spots in their home/office where heat may be entering (e.g., via a crack, window, or other opening) or where heat/cold air is escaping. Such information may be useful for detecting and fixing leaks in an environment.

The additional circuitry may further include a microphone sensor for receiving voice input commands from a user. For example, the fan module 102 may receive voice commands such as “fan on” to cause the fan to begin circulating air in a surrounding environment. In another example, the fan module 102 may include a voice command such as “fan on me” to cause the fan to target (e.g., via rotation by pan/tilt mechanism 106) the user who spoke the command to direct air flow in their general direction. Likewise, “fan off me” or “fan move left/right/up/down” may further be suitable voice commands for adjusting operation of the fan module 102. Voice commands may also be utilized to change fan speed of the motor and fan 108 and/or may be utilized to select a particular output fragrance. The user may therefore utilize voice and/or other commands, e.g., commands executed via an app, to cause the air treatment system to switch from a semi-autonomous mode to a manual mode for a predefined period of time to ensure air circulation comports with a user's desired configuration.

In some cases, the user device 118 may receive/capture the voice commands via a local microphone and transmit the same to the fan module 102 to cause the same to change operation accordingly.

Turning to FIG. 2, a block diagram shows a side view of the air treatment system 100 in accordance with various aspects and embodiments of the present disclosure. As shown, the fan module 102 includes a housing comprised of a base portion 240 and a spheroid fan portion 241 (or fan body 241). In some embodiment, the base portion 240 includes at least two arms extending therefrom to hold the fan body 241 securely in position, which are better shown in FIGS. 3-5. However, the base portion 240 may include less arms, e.g., one arm as shown in the embodiment of FIGS. 14A-14G, or more than two arms depending on a desired configuration. A first end 242, or module coupling end, of the base portion 240 may include a coupling receptacle for coupling with the optional filter 120 and/or optional humidifier 122. A portion of the pant/title mechanism 106 may be disposed adjacent the module coupling end 242 and may allow the base 240, and by extension the fan body 241, to rotate about the longitudinal axis 250 (e.g., to provide movement/rotation along a horizontal axis).

A second end 247, or fan coupling end, of the base portion 240 may couple to the fan body 241. The fan body 241 may couple to base 240 by a second portion of the pan/title mechanism 106, with the second portion of the pan/title mechanism 106 allowing for up/down movement, or more particularly, movement along the longitudinal axis 250. Thus, the pan/tilt mechanism 106 of the fan module 102 allows for 360 degrees of movement to direct output air 150 towards virtually any location within an environment.

The fan body 241 is not necessarily limited to a sphere shape and may instead comprise any regular or irregular shape that provides at least one convex surface. For example, the fan body 241 may comprise an ellipsoid, oval or sphere, although these examples are not intended to be limiting.

In any event, the fan body 241 includes a nozzle 243 which defines at least one outlet 244, with the nozzle 243 being configured to output air 150 along convex surface 245. As shown, the Coanda effect results in air 150 generally following convex surface 245 such that the air is generally is substantially output in direction D. Accordingly, air 150 may travel externally and not necessarily through a passageway provided through the fan body 241. However, aspects and embodiments are equally applicable to nozzles that expel air through a passageway that extends substantially through the center of the fan body.

The intake 112 may be adjacent the module coupling end 242. The intake 112 may be fluidly coupled via one or more passageways within the base 240 which extend substantially in parallel with the longitudinal axis 250.

Referring to FIGS. 3-5 the air treatment system is shown in accordance with embodiments disclosed herein. FIG. 3 shows an air treatment system 100A including only the fan module 102. As shown, intake 112 includes at least one semi-permeable region (e.g., a mesh) to receive air, e.g., air 140. Air 140 may then be provided via passageways/channels in one or both of arms 302-1, 302-2 to the fan body 241. As shown, a fragrance unit 310 (or fragrance diffuser) may be placed on (or adjacent) the intake 112 and output an adjustable amount of fragrance towards the bottom of the fan body 241. Air, e.g., air 150, output by the nozzle 243 may then combine with the fragrance and thus cause air 150 to have a predefined scent. The fragrance unit 310 may include one or more scents (e.g., provided by oils or gels or fabrics impregnated with scent) which may be mixed, heated and/or blown (e.g., via a fan within the fragrance unit 310) to produce a desired fragrance at a desired intensity. The fragrance unit 310 may be powered by a battery. Alternatively, or in addition, the fragrance unit 310 may be powered by electric contacts located on the base 240. The fragrance unit 310 may be controlled via the controller 104.

In some cases, the fragrance unit 310 may include a battery and charger circuit to allow the unit to be “charged” via the base 240 and deposited in another location with an environment to operate independent of the base 240. The fragrance unit 310 may be remotely controlled via the user device 118 (or controlled indirectly by commands routed through the fan module 102).

FIG. 6A shows one example embodiment of an air treatment system 100D creating room-wide airflow. In an embodiment, the fan module may point directly/substantially upward and may use one or more image sensors to determine a center of the ceiling. Once determined, a convection current may be identified that circulates hot air and causes the same to normally stagnates adjacent the ceiling. The fan module 102 may efficiently target such hot/stagnate air and direct cooler air to disrupt the same. Thus, stratified layers of air of different temperatures may be mixed efficiently to circulate air fully through an environment.

As shown in FIG. 6B another example embodiment of an air treatment system 100D is shown. As shown, the fan module may move in a spiral fashion so as to force hot or stagnant/dirty air from the top layers of an airspace adjacent a ceiling. For example, the fan module may begin facing upwards towards the ceiling and then start by rotating in full continuous revolutions about the base vertical pan axis 610 while slowly tiling down from the upward-facing position. Thus, a spiral may be transcribed by a resulting air stream to force room air downward towards a filter of the air treatment system, for example.

FIG. 7 shows an example embodiment where air treatment system 100E is in communication with air treatment system 100F to provide room-wide/environment-wide circulation. In this embodiment, each air treatments system may share their present direction with each other, e.g., via wireless connection 120, to ensure that their respective outputs are not directly pointed at each other, and instead covering different areas within the environment.

FIG. 9 shows an example embodiment of a fan module 102D in accordance with an aspect of the present disclosure. As shown, the air is taken in through the base, e.g., via intake 112, and brought up to the spheroid fan portion. A change over valve may then direct air through the spheroid fan portion.

FIG. 10 shows another example embodiment of a fan module 102E. in this embodiment, hinged elements 1002 allow the spheroid fan portion to “open” similar to a flower to widen an air path for air 150.

FIGS. 11A-11C show the module 102E of FIG. 10 during various stages of opening/closing. As shown, a stretchable material (e.g., fabric) surrounds the spheroid fan portion. A distal end of the hinged elements 1002 is coupled to a ring 1104 which is concentric about an axle 1106. As the ring 1104 travels towards the disc portion 1108 the spheroid shape widens by function of the hinged elements 1002 extending substantially orthogonal relative to the axle 1106. As shown in FIG. 11C, this results in a wider spheroid shape relative to the shape shown in FIG. 11A.

FIGS. 12A-12C show an additional configuration in accordance with aspects of the present disclosure. As shown, fan module 102F includes fan inlets within an opening of the base 240.

FIGS. 13A-13D show an additional configuration in accordance with aspects of the present disclosure. As shown, the air treatment system 100G includes an air filter 120 which is in fluid communication with base 240.

FIGS. 14A-14G show an additional configuration in accordance with aspects of the present disclosure. As shown, the air treatment system 100H includes a fan module with a single arm extending from base 240.
