Description

The present invention relates to an air treatment system, and more particularly to a portable indoor air filtration system.

Demand for air treatment systems continues to grow, as concerns about air quality remain an important concern. This growth has led to increased use of commercial and residential air treatment systems. A conventional residential air treatment system is a built-in unit that can be placed in a room where it is desirable to treat the air. Residential air treatment systems are generally operated by drawing indoor air into it, treating it using one (or more) techniques, and releasing the treated air back into the room. The treated air contains lower concentrations of air pollutants than in the entire room. The treated air mixes with the room air, thus reducing the concentration of pollutants in the room air.

Air treatment systems are available using various types of control systems. The control system provides various methods for controlling the operation of the air treatment system and for allowing the operator's input. The design and configuration of the control system can have a significant impact on the function and aesthetic appeal of the air treatment system.

Many conventional air treatment systems include a series of specialized filters adapted to address specific issues regarding air quality. For example, residential air treatment systems often include pre-filters, particle filters, and odor filters. The function of the pre-filter is typically to remove relatively large elements such as hair and dust lumps from the air. Particle filters typically function to remove smaller airborne particles. Particle filters are available in a variety of configurations. For example, the particle filter may include pleated material using non-woven fibers that capture the particles and are effective as a HEPA filter. Odor filters are also available in various types and configurations. Many odor filters include, but are not limited to, activated carbon that adsorbs a group of impurities such as many organic chemicals. Conventional particle filters and carbon filters have a limited life and require occasional replacement. The structure of the air treatment system and the mechanism used to secure the filter within the air treatment system has a significant impact on the effectiveness of the system and is dramatic to the effort and complexity required to replace the filter. Affects

There are other aspects that can affect the functionality and commercial success of air treatment systems. For example, convenient features such as power cord operation and mobility features such as the foot and handle can affect the user's experience.

The present invention provides an air treatment system with an improved control system.

In one embodiment, the control system includes a "dead front" display that gives the ATS a clean and simple look and facilitates an improved control experience. The display may include a plurality of information type display elements and a plurality of touch sensors that are selectively lit by a light source arranged below such as an LED. In order to generate the desired pattern, each light source may be covered by a screen having a mask layer and a diffusion layer. A translucent cover may be placed above the control system to hide the underlying structure so that the design image is visible only when lit. A translucent cover may be incorporated into the removable front cover that closes the front of the ATS. In one embodiment, the electronic component module comprises an optical duct assembly having a plurality of individual ducts joined side by side to direct light from a light source to a corresponding display element.

In one embodiment, the touch sensor is a capacitive sensor. In such an embodiment, a capacitive film such as a transparent PET film coated with indium tin oxide may be incorporated into the structure above each light source. For example, each light source may be covered with a laminated screen containing a mask layer and a diffusion layer, or a capacitive coating may be mounted as an additional layer of the screen. As another example, the capacitive coating may be separated from the screen and may be located above or below the screen where it can sense the presence of the operator's finger. In one alternative embodiment, the conductive trace element may be incorporated into a structure above each light source to act as a capacitive sensor. For example, a printed circuit board (“PCB”) may be placed on top of the optical duct array. The PCB may define an opening above each of the individual light ducts, or may include a trace element associated with the light duct for the input display element around each opening. The PCB may also include a relatively large conductive trace element that extends over a significant portion of the surface of the PCB to provide a capacitive sensor that is sensitive enough to function as a proximity sensor. The proximity sensor may be configured to detect the presence of an operator (eg, the operator's hand) within approximately 2 feet (60.96 cm) of the display.

In one embodiment, the ATS has a removable front cover located above the display, and the control system recognizes the touch differently depending on whether the cover is attached or removed. It is configured to do. This allows the user to control the system with or without the cover in the correct position. In one embodiment, the control system is configured to allow different sets of control options depending on whether a cover is attached or not. For example, the control system may provide a reduced set of control options and / or additional control options when the cover is removed. The control system can use one or more capacitive touch sensors, such as a proximity sensor, to recognize whether the cover is attached or detached.

In one embodiment, the control system comprises a dust sensor embedded within an electronic component module. The dust sensor can be arranged so that air is drawn into the dust sensor by the force of the partial vacuum created by the ATS blower. After passing through the dust sensor, the air passes through the filter and is returned to the room in a treated state. Alternatively, the dust sensor may be arranged such that air is drawn into the dust sensor by the force of the treated air flow discharged by the ATS.

In another aspect, the invention provides a magnetic interlock on the front cover, which not only allows for easy installation and removal, but also allows the control system to recognize whether the cover is installed or not. It is possible to make it. In one embodiment, the front cover comprises one or more mechanical attachments at the top and one or more magnetic attachments at the bottom. The mechanical attachment may include edges configured to remain in the corresponding structure within the housing of the ATS. For example, the edges may remain on the electronic component module to help ensure a snug alignment between the front cover and the electronic component module. The size, shape, and configuration of the fastener can vary. For example, it may extend over the entire width of the front cover, or it may extend only to the central portion of the front cover. As another example, the edges may be integrally formed with the front cover or may be separate components that are attached to the front cover after manufacture. The front cover may be made of translucent plastic, which is configured to provide an opaque appearance while allowing light from the display to pass through. In one embodiment, the exposed surface of the front cover may be covered with a film applied using the in-mold film method. In another embodiment, the exposed surface may be covered with a thin layer of paint using a spray method or a direct transfer method (ie, silk screen printing or pad printing, or thermal film transfer). Alternatively, the front cover may be substantially opaque and may include a window over the display. The windows may be made of translucent plastic, which is configured to provide an opaque appearance while allowing light from the display to pass through. In one embodiment, the exposed surface of the window may be covered with a film applied using the in-mold film method. In another embodiment, the exposed surface of the window may be covered with a thin layer of paint using a spray method or a direct transfer method (ie, silk screen printing or pad printing, or thermal film transfer).

In another aspect, the invention provides an ATS housing with a replaceable base. The number and mode of bases may vary, but in one embodiment the ATS may include multiple bases that provide different structures for receiving the power cord and / or different feet for supporting the ATS. For power cords, the ATS may be able to accept either a structure for manually winding the power cord or a base with a retractable cord assembly with an automatic take-up reel. For the foot, the base may include a fixed foot, casters, wheels, and / or a single elongated roller. As an alternative to the replaceable base, the base may be incorporated into the ATS and may include a foot and a single elongated roller. The ATS may include a handle at the top rear of the housing. In one embodiment, the handle may extend essentially across the width of the ATS to allow the ATS to grab the center with one hand or to grab both sides with both hands.

In another aspect, the invention provides a filter cage assembly that allows for easy and secure mounting of the filter. In this embodiment, the ATS includes a particle filter and an activated carbon filter. First, the activated carbon filter is fitted into the filter housing, and the particle filter is fitted into the filter housing so as to cover the carbon filter. The particle filter is secured to the ATS housing at its outer circumference by one or more clips that interact with the corresponding structure in the ATS. One or more clips may be configured to act like a cam to tighten the particle and carbon filters in place. The ATS may also include a pre-filter that snaps into the particle filter. The pre-filter may include a coarse filter medium supported by a grid pre-filter cage.

The present invention provides an ATS with an improved control system. The use of the built-in electronic module allows the testing and calibration of electronic components prior to the installation and assembly of the ATS. It also facilitates the replacement of electronic modules as needed. For example, by using the dust sensor mounted on the board together with the integrated duct system, it is not necessary to separately mount the dust sensor and wire the dust sensor to the electronic component module. The control system includes a "dead front" display with an integrated capacitive touch sensor. This enables a fully sealed electronic component module with no moving parts, providing improved reliability. The use of a "dead front" display allows for a dynamic display that changes from mode to mode, not only providing an improved aesthetic, but also simplifying the display and making it easier to switch from one mode to another. Promote operation. The use of LEDs with multiple color or brightness options allows the display elements to be lit in different configurations depending on the use. With wireless connectivity, remote devices such as smartphones and tablets can be used to control and exchange data, including data logging and monitoring of historical trends, without the need for a light of sight or infrared transmissive plastic. Become. RFID tags can provide improved tracking and monitoring of filter life and product effectiveness, allowing resetting of filter life without operator intervention. The dust sensor may be used not only to control the blower speed, but also to provide a more accurate filter life calculation. In another aspect, the ATS includes a front panel that can be easily removed and attached with one hand without the need to bend deeply or kneel to reach the attachment. The front cover can cover the electronic component module to provide a "dead front" display by having at least a partially translucent window or a partially translucent window. In addition, the side and center inlets allow air to enter the ATS freely. In another aspect, the interchangeable base allows the ATS to be easily customized for different applications and customers with different tastes. This provides additional flexibility and rapid switching between models with different characteristics. For example, there may be various types of feet, and there may be various types of features of chord operation. The use of an integral handle that extends approximately relative to the width of the ATS offers various advantages. As a result, the operator can operate the ATS with one or both hands at various wrist / hand angles. It can also be formed to provide structural reinforcement under the cantilever feature of the ATS. In one embodiment, the base can include casters or center rollers that allow one hand to be placed around the center of the handle to easily move the ATS. In another aspect, the invention provides a simple and effective arrangement of clips for immobilizing ATS particle filters. By placing one or more clips near the top of the filter and near the bottom of the fasteners, the filter can be secured and opened without deep bending or kneeling. One or more clips may provide improved sealing by automatically engaging them more closely as the filters engage the sealing surface. The one or more clips also work in only one direction, thereby ensuring that the filter is mounted in the correct orientation.

FIG. 1 shows an air treatment system (“ATS”) according to an embodiment of the present invention. The ATS 10 of the exemplary embodiment generally includes a pre-filter 100, a particle filter 102, and an activated carbon filter 104. The ATS 10 also includes a blower 56 that draws air from the environment into the ATS 10, passes the air through a filter, and returns the filtered air to the environment.

An exemplary embodiment of the ATS 10 includes a control system 12 having an electronic component module 14 that provides a "dead front" display 16. The display 16 of this embodiment includes a plurality of display elements 18 that can be selectively lit by the control system 12 to provide dynamic content. Some of the display elements 18 may include a touch sensor 20 that allows operator input.

[B. General structure]
As mentioned above, the invention is described in the context of an indoor air treatment system that exerts its general function by activating a blower 56 to pass air through a series of filters 100, 102, and 104. The air treatment system 10 of the exemplary embodiment is configured to treat air in three stages of filtration. The first step is a coarse mesh pre-filter 100, which removes large debris such as hair, cotton fibers, and large lumps of dust (eg, "dust-bunnies"). Intended to be. The second stage of filtration is the particle filter 102. Although there may be various specifications for the particle filter 102, the exemplified ATS 10 includes a pleated HEPA filter medium, which reduces aerial particles as small as 0.009 microns. The third stage of filtration is an activated carbon filter 104 containing an underlay of granular activated carbon pieces coated with various catalysts that adsorb and convert molecular contaminants such as formaldehyde, dioxin, and ozone. The carbon filter 104 was prepared on January 8, 2008 by Taylor, Jr. They may be manufactured in accordance with the teachings of US Pat. No. 7,316,732 to AIR TREATMENT FILTER AND RELATED METHOD, which are incorporated herein by reference in their entirety.

In an exemplary embodiment, the various filters 100, 102, and 104 are fitted into the filter housing 112. The filter housing 112 generally includes a carbon filter receiver and a particle filter receiver. The two receivers are substantially rectangular cavities configured to receive carbon filters and particle filters, respectively. The carbon filter receiving part is somewhat smaller in height and width than the particle filter receiving part. As a result, the filter housing 112 is stepped and has a shoulder 114 surrounding a carbon filter receiving portion. The carbon filter 104 is first fitted into the filter housing 112. The external dimensions of the carbon filter 104 are slightly smaller than the dimensions of the portion of the filter housing 112 that is intended to receive the carbon filter 104. As a result, there is a relatively tight fit between the carbon filter 104 and the filter housing 112, which causes air to move through the carbon filter 104 rather than around it. Next, the particle filter 102 is fitted into the filter housing 112. As described above, the filter housing 112 is stepped and includes a shoulder 114 to which the particle filter 102 is attached. The particle filter 102 may include an end face seal (not shown) that engages the shoulder 114 to provide a leak-proof seal between the particle filter 102 and the filter housing 112. This directs all air passing through the ATS 10 to flow through the particle filter 102 rather than around it. Next, the front filter 100 is fitted inside the filter housing 112 to the outside of the particle filter 102. In this embodiment, the pre-filter 100 includes a frame portion 116 and a layer of filter medium (not shown). The frame portion 116 is configured to snap directly to the particle filter 102. For example, the frame portion 116 may include a finger portion 117 that extends inward and can engage the particle filter frame portion. Except for the ranges described, the pre-filter 100, particle filter 102, and carbon filter 104 are generally conventional and therefore not described in detail. Although the illustrated embodiment comprises a three-step filter arrangement, the invention may be incorporated into the ATS with different filtration / treatment arrangements.

In this embodiment, the ATS 10 includes untreated air inlets 106a-c in the front that allow air to enter the system and an air outlet 108 in the rear that returns the treated air to the environment. The ATS 10 includes a front filter 100, a particle filter 102, and a blower 56 housed behind a carbon filter 104 in the rear lower portion of the housing. In operation, the blower 56 draws untreated air from the environment into the ATS 10 through inlets 106a-c and continuously passes the air through three filters 100, 102, and 104 to treat the air and then treat it. It operates to expel air through outlet 108 and return it to the environment. The size, shape, and configuration of the inlets, outlets, and internal channels are designed, among other things, to provide quiet and efficient operation while providing an ATS with a small footprint. The sizes, shapes, and configurations of the inlets, outlets, and internal channels may vary from application to application, if desired.

The exemplified ATS 10 is merely exemplary, and the size, shape, and configuration of the ATS may vary depending on the application.

[C. Control system]
As mentioned above, the invention includes a control system 12, which provides a user interface for controlling the operation of the ATS 10 to display information and to accept input from the operator. The main function of the control system 12 is to control the operating speed of the ATS 10 to process the air based on the sensed parameters or the operator's input, to track and monitor the filter usage, and to the operator the mode, motor. Notify the speed setting and filter life, and accept the operator's command. In general, the control system 12 changes the speed at which the air is filtered by adjusting the speed of the blower 56. More specifically, the control system 12 controls the operation of the blower 56 based on an automatic or manual control method, as described in more detail below. The control subsystem 60 may be configured to slowly transition between each speed of the blower as desired. For example, in an exemplary embodiment, blower speed control is achieved by varying the load cycle of the power supply supplied to the blower 56. To provide a slow transition between motor speeds, the control subsystem 60 shifts from one speed to another by slowly increasing or decreasing the load cycle from the current speed to the desired speed. You may. The timing, number, and size of the steps may vary depending on the application, depending on the desired effect.

In an exemplary embodiment, the user interface is implemented as a "dead front" display 16, which is located closer to the top of the front cover 32 and includes a built-in touch sensor. In use, the display 16 displays information and accepts operator input related to system operation and maintenance. For example, the control system 12 of the exemplary embodiment displays dust levels in the current environment and information about the remaining life of the various filters. It also provides contact sensitive buttons that allow the operator to control the system. The "dead front" display 16 includes a plurality of display elements 18 that are visible only when lit. The control system 12 is configured to selectively light individual display elements 18 to provide varying dynamic displays to provide information and to present control options available at any given time. Will be done. In an exemplary embodiment, the display 16 has an information type display element 18a that is lit to provide information about the state of the ATS or the monitoring characteristics such as the air quality of the environment and the filter life, and the operator inputs. It includes an input display element 18b that incorporates a touch sensor to enable it to be provided to the control system 12. In addition to allowing user input, the input display element 18b may also provide information about the state of the ATS, such as operating mode and blower speed.

In an exemplary embodiment, the control system 12 is built-in in the sense that it includes all of the electronic components of the ATS 10 except for the power supply components that convert the AC wall power to the DC power needed to operate the ATS 10. Includes electronic component module 14. In this embodiment, the power supply component (not shown) is located in the base 40 of the ATS housing 110. Here, referring to the schematic explanatory view of FIG. 4, the electronic component module 14 generally has a control subsystem 60, an LED array 62, a capacitive touch sensor array 64, a dust sensor assembly 66, an RFID subsystem 68, and a wireless communication sub. Includes system 70. The control subsystem 60 includes a control circuit and firmware, which activates the ATS10 and includes a capacitive touch sensor array 64, a dust sensor 66, an RFID subsystem 68, and various other subsystems including a wireless communication subsystem 70. It is configured to coordinate the collection of data from the system. The various modes of operation of the system are described in more detail below. The control subsystem 60 also includes not only pre-programmed operation-related default values, but also the lifetimes, usage times, counters of filters 100, 102, and 104, and other variables that may be used in connection with the operation of the ATS 10. Includes non-volatile memory for storing operation-related historical data as well.

The electronic component modules 14 of the illustrated embodiment are shown in FIGS. 5 to 7. As shown, the electronic component module 14 is a housing containing a circuit of a control subsystem 60, an RFID subsystem 68 and a wireless communication subsystem 70, as well as an LED array 62, a capacitive touch sensor array 64, and a dust sensor assembly 66. Includes 148. The housing 148 generally includes a base 150 and a cover 152. As described above, the LED array 62 is configured to provide lighting for the display element 18. More specifically, the one or more LEDs 62a are located behind each display element 18 including the information type display element 18a and the input display element 18b. The LED 62a can be selectively lit by the control subsystem 60 when it is appropriate to indicate the information type display element 18 or make the input display element 18b available for input. Each LED 62a may include a single LED or a plurality of LEDs that provide various lighting options. For example, each LED 62a may include a plurality of LEDs having different brightness so that the brightness of the display element 18 can be changed. As another example, each LED 62 may include LEDs of different colors that can be combined or lit separately to produce different colors of lighting. In one embodiment, each LED 62 comprises a red LED, a green LED, and a blue LED, which are lit at different levels of brightness in different combinations so as to provide lighting of essentially any desired color. Can be done. In another example, each LED 62a may include multiple LEDs of different brightness and different colors. Illustrated embodiments include LED arrays 62 to provide lighting for the display 16, but the LED array 62 may be replaced or supplemented with other types of light sources such as OLEDs, lasers, and EL light sources.

In an exemplary embodiment, the display 16 is a "dead front" display in which the unlit display element 18 is invisible. In this embodiment, the area where the display 16 is located appears to be merely a continuous portion of the ATS housing 110, and when the display element 16 is not lit, the ATS 10 appears to have no user interface. In order to generate the desired symbol elements, each display element 16 includes a screen 74 that masks and diffuses the light generated by the underlying LED 62. In an exemplary embodiment, the display 16 includes two screens 74a and 74b, each covering a plurality of LEDs to provide a masking and diffusing function for the plurality of display elements 18. The screen 74a provides and is associated with an information type display element 18a that provides information related to the lifetimes of the different filters 100, 102, and 104. The screen 74b includes an information type display element 18a that provides information about the air quality of the environment (eg, based on dust sensor readings), and an input display element 18b associated with power, mode, and blower speed inputs. Is associated with. In an exemplary embodiment, each screen 74 has a laminated structure and generally includes a diffusion layer and a mask layer. The diffusion layer may be basically any material capable of diffusing the light generated by the LED. For example, the diffusion layer may include a transparent substrate covered with a translucent film or other translucent coating. Alternatively, the diffusion layer may be a transparent material with a "coarse" or rough surface. In another alternative form, the diffusion layer may be a sheet of translucent material. The mask layer is essentially any material that can mask light to produce the desired pattern, including various opaque and translucent materials such as inks, paints, films, and other adhesive layers. There may be. For example, the mask layer may be a layer of opaque membrane that defines one or more openings in the shape of the desired pattern. It may also include a combination of different materials that provide different appearances. For example, the mask layer may include an opaque region where light transmission is not desired, a first translucent material where background light transmission is desired, and a second translucent material where foreground light transmission is desired. .. The first and second translucent materials may produce regions that appear different due to the use of translucent materials of different colors or translucent materials with different levels of transparency. The mask layer may be applied to the diffusion layer by printing, thermal adhesion, adhesive, or other suitable means. In an exemplary embodiment, the mask layer is placed on the outer surface of the diffusion layer opposite the LED or other light source, but may be placed elsewhere if desired. The diffusion layer and the mask layer are part of a single laminated structure in the exemplary embodiment, but instead they may be separate components. For example, they may be manufactured separately and placed adjacent to each other during assembly of the display 16.

In an exemplary embodiment, the optical duct array 72 has a plurality of individual ducts 72a joined side by side to allow light to enter and be guided from the light source to the corresponding display element. Each light duct 72a surrounds a light source and provides a reflective duct that transmits light from the light source 62a to the appropriate portion of the screens 74a, 74b. For example, as shown in FIG. 3, one end of each optical duct 72a may be configured to be in close contact with the LED 62a, with the other end engaging and associated with the screen 74b. The size and shape may follow the outer circumference of 18. The inner surface of each light duct 72a may have other optical properties that are reflective, diffuse, or selected to provide the corresponding display element 18 with the desired appearance. In an exemplary embodiment, the electronic component module 14 includes two optical duct arrays 72, one for the filter life display and one for the rest of the display elements. In this embodiment, each optical duct array 72 is manufactured as a single integrated unit, which facilitates the manufacture and assembly of the electronic component module 14. For example, each optical duct array 72 may be injection molded and the inner surface may be coated with a reflective or diffusive material, depending on the desired appearance.

As mentioned above, some of the display elements 18 are input display elements 18b that function as touch sensors to allow the operator to provide input to the control subsystem 60. The input display element 18b may be implemented using essentially any touch sensor technology that may be incorporated into a "dead front" display. In an exemplary embodiment, the input display element 18b is a capacitive touch sensor. In this embodiment, the display 16 includes a capacitive touch sensor array 64 that includes a plurality of separate sections of the capacitive coating 64. Each section of the membrane is associated with a single touch sensor. For example, each section of the membrane may have the same extent as the display element 18b associated with the touch sensor. The capacitive film 64 may be incorporated into the screens 74a and 74b as a separation layer to be laminated on the diffusion layer 76 and / or the mask layer 78, for example. Alternatively, the capacitive film 64 may be separated from the screens 74a and 74b. In an exemplary embodiment, each section of the capacitive coating 64 includes a tab 65 or other feature for connecting to the electronic module 14, and the underlying substrate 67 provides a common underground. Monitoring, control, and operation of capacitive touch sensors may generally be conventional and are therefore not described in detail. The control subsystem 60 sequentially takes readings from separate sections of the capacitive coating and recognizes the touch by determining that the touch has occurred when the current reading matches a predetermined value typical of the touch. I'll just say that it's okay.

As mentioned above, the electronic component module 14 of the exemplary embodiment includes a dust sensor assembly 66 that allows the control system 12 to measure the level of airborne contaminants. In this embodiment, the dust sensor assembly 66 includes a dust sensor 80, a sensor inlet 82, a sensor duct 84, a sensor outlet 86, and a pair of sensor gaskets 88. In this embodiment, the dust sensor assembly 66 utilizes the partial vacuum created by the blower 56 to draw environmental air through the dust sensor 80. After passing through the sensor 80, the air is processed and returned to the environment. As shown, the sensor outlet 86 communicates with the air flow path through the ATS 10 and is located upstream of the filters 100, 102, and 104. The sensor 80 is correctly aligned with the sensor outlet 86 and attached to the electronic component module 14. The sensor inlet 82 is located on the cover 152 of the electronic component module 14 and provides a passage for environmental air to enter the sensor duct 84. The sensor inlet 82 may include filter material (not shown) selected to prevent large particles such as hair, cotton, and lumpy dust from clogging the dust sensor 80. The filter material may be replaceable or washable. The sensor duct 84 is arranged between the sensor 80 and the sensor inlet 82 and provides a flow path to the sensor 80. The sensor gasket 88 is located between the dust sensor 80 and the sensor outlet 86 and between the dust sensor 80 and the sensor duct 84. In operation, the blower 56 draws air from the environment through the sensor inlet 82, the sensor duct 84, the dust sensor 80, and the sensor outlet 86 in sequence. As the air passes through the dust sensor 80, the level of dust in the air is measured using known techniques and devices.

Although not shown, the ATS 10 may also include a sensor capable of providing an indication indicating the presence or absence of the front cover 32. For example, in an exemplary embodiment, the ATS 10 includes a Hall effect sensor located near the bottom of the ATS 10 and near one of the magnetic mounts. When the front cover 32 is removed, the absence of the magnet changes the reading provided by the Hall effect sensor. Alternatively, a separate interlock magnet (not shown) can be used to determine the presence or absence of the front cover 32 using a Hall effect sensor, reed switch, or other magnetic field sensor mounted on the electronic component module 14. ) May be incorporated in the front cover 32 at a position near the electronic component module 14. Information about the condition of the front cover 32 can be used by the control subsystem 60 to influence the operation of the system. For example, in one embodiment, the control subsystem 60 may automatically stop the blower 56 or otherwise alter its function when the front cover 32 is removed. As another example, when the front cover 32 is removed, the control subsystem 60 may change the parameters used in determining if a touch has occurred. This allows the touch sensor to operate equally correctly with or without the front cover 32 in the correct position. As a further example, the control subsystem 60 may enter an alternative mode of operation when the front cover 32 is removed. Thereby, the control subsystem 60 may change the display element 18, including the available input display element 18b.

The control system 12 may also include an RFID subsystem 68, which is configured to work with the corresponding RFID tag of an interchangeable filter (eg, particle filter 102 and / or activated carbon filter 104) in ATS10. RFID subsystem 68 is generally conventional and therefore not described in detail. The control subsystem 60, along with the RFID subsystem 68, includes filter life, time of use, elapsed time since installation, total impact connection (eg, motor speed multiplied by time of use), and RFID tags. It just allows other data to be aggregated, stored, and stored like any other. When the filter is installed, the RFID reader / writer will receive any data already stored on the RFID tag, such as the filter life, the total amount of time the filter was attached to any system, and the total effect consumption of the filter life. Can also be read. In this way, the system can provide correct tracking and monitoring even if the filter is moved from one ATS to another. The RFID tag embedded in the filter may also contain a sequence number that can be used to verify that the filter is authentic. For example, the control system 12 may store a valid sequence number table for comparison and comparison of sequence numbers, or if it has network functionality, it may be sequenced against a valid sequence number table stored on the Internet. It may have the ability to compare numbers. Filter usage information may be used to provide an indication of the remaining life of the filter and to provide a prompt if the filter needs to be replaced. RFID subsystem 68 may also be used to determine when the filter has been removed. This information may be useful in managing or maintaining statistics on the use of ATS10. For example, the control subsystem 60 may be configured to stop the blower when the particle filter 102 and / or the carbon filter 104 is removed. In another example, the control subsystem 60 may enter service mode when one or both of the filters are removed. When in service mode, the control subsystem 60 displays information technology information and / or provides specific control options for that mode. To help ensure correct alignment between the RFID reader / writer in ATS10 and the RFID tag in carbon filter 104, the carbon filter 104 is mounted so that the carbon filter 104 is mounted only in the orientation that provides the alignment. And the filter housing 112 may be keyed. For example, the bottom of the particle filter 104 may include a keyway (not shown) and the filter housing 112 may include a corresponding key (not shown). When the RFID reader / writer is centered in the left-right direction, it does not matter which filter surface faces inward, so the key may be centered. If the RFID reader / writer is not centered, it may be beneficial to provide an asymmetric keyboard layout to ensure that the desired filter surface faces inward.

As described above, the control system 12 allows the control subsystem to wirelessly communicate with other electronic devices such as smartphones, tablets, personal computers, local wireless routers, broadband wireless routers, and other communication devices. The communication subsystem 70 may be included. In an exemplary embodiment, the wireless communication subsystem 70 allows the ATS 10 to exchange information with remote devices such as smartphones or tablet devices running dedicated applications and accept commands from them. For example, an application may be provided that allows an operator to enter an ATS command that is wirelessly transmitted to and executed on a control subsystem 60 on an electronic device. As another example, the information collected by the ATS 10 can be transmitted to the electronic device for display within the application. In an exemplary embodiment, this may include filter life information, mode operation information, motor speed information, and environmental air quality information derived using dust sensors for each filter. The wireless communication subsystem 70 may basically utilize any wireless communication technology and protocol. For example, in an exemplary embodiment, the wireless communication subsystem 70 may have Bluetooth® and / or WiFi functionality.

The control system 12 may be configured to execute a wide variety of control methods. In each case, the control system 12 may be configured to provide a dynamic display 16, in which the display element 18 is lit, the touch sensor is operated mode and the values of the monitored parameters, etc. It becomes possible to operate based on changing the variable. In an exemplary embodiment, the control system 12 implements a control scheme having four general operating modes, which are "smart" modes in which control is automated, at least in part, based on dust sensor readings. Or automatic mode), a "manual" mode in which the operator controls the blower speed, a "turbo" mode in which the blower 56 is temporarily operated at high speed, and the display 16 limits lighting at night. Includes a "night" mode that behaves differently as it does. In connection with this control method, the display 16 can display various information type display elements 18a and input display elements 18b (see FIGS. 5 and 9A). In an exemplary embodiment, each display element 18 comprises two LEDs of different colors and / or different intensities. One of the two LEDs is used to light a display element in a "present" state (eg, a darker LED, or a first color such as a subdued color). This lighting state is used to make the display element 18 visible on the display 16 while at the same time providing a visual indication that it has not been selected or is not valid. The other LED is used to light the display element in the "on" state (eg, a brighter LED, or a second color, such as a brighter color). The "on" state is used to indicate that the display element is "on" or "valid". The number, type, arrangement, configuration, and operation of the display elements 18 may vary largely depending on the application, largely depending on the control method performed by the control system 12.

In the exemplary embodiment, the information type display element 18a includes an information type display element 200 representing the pre-filter life, a set of information type display elements 202 representing the particle filter life, and a set of information type display representing the carbon filter life. It includes element 204 and a set of information type display elements 206 that represent the dust level of the environment (see FIG. 9B). The input display element 18b generally comprises a power input display element 208, a "smart" mode input display element 210, a "turbo" mode input display element 212, a "night" mode input display element 214, and a plurality of blower speed input display elements 216. Includes (see Figure 9B).

In an exemplary embodiment, the different filter life displays 200, 202, and 204 are located between the front cover 32 and the icon display of the ATS housing 110 (see FIG. 9B). These icons can help identify which filter life display is associated with which filter. In an exemplary embodiment, the front cover and ATS housing icons are statically lit by a white LED that operates at 50% brightness.

In an exemplary embodiment, the filter life display 200 for the pre-filter is in a "current" state where the pre-filter does not require maintenance and "on" where the pre-filter requires maintenance (cleaning or replacement, etc.). Includes an information type display element 200 that can be lit in the state. The "current" state may be created by statically lighting the green LED. The "on" state may be provided by blinking the red LED.

In an exemplary embodiment, the filter lifetime display 202 for the particle filter 102 includes four information type display elements 18a, each representing a quarter of the filter lifetime. When the filter life display is on, all four display elements 18a are lit. The number of elements 18a lit in the "on" state represents the remaining life of the filter. The remaining elements 18a are lit in the "current" state and provide a visual indication that the filter life is expressed in quarters. The number of categories may vary depending on the application, if desired. For example, further fineness may be provided by increasing the number of informational display elements 18a associated with the filter lifetime display 202. In an exemplary embodiment, the filter life display 202 for a particle filter incorporates a color LED to help represent the filter life as follows.
75-100% life-All four categories light green at 100% brightness 50-75% life-The bottom three categories turn green at 100% brightness,
The top section lights up in white with 50% brightness 25-50% life-The bottom section is 100% bright and amber
The top three categories light up in white with 50% brightness 1-10% life-The bottom category turns red with 100% brightness
The top three categories light up in white with 50% brightness 0% lifespan-The bottom category turns red with 100% brightness,
In the exemplary embodiment, the filter lifetime display 204 for the carbon filter 104 is essentially the same as the filter lifetime display 202 for the particle filter 102, as described above. Includes four display elements 18a that can be lit in the "current" or "on" state using the same method as above.

In an exemplary embodiment, the dust level display 206 comprises a plurality of individual information type display elements 18a that can be lit in the "current" or "on" state. When the dust level display 206 is displayed, the number of information type display elements 18a that are lit in the "on" state represents the measured dust level, and the other information type display elements 18a are lit in the "current" state. Will be done. This allows the operator to better understand the dust level by comparing the ratio of the "on" divisions to the total number of divisions. In the exemplary embodiment, the dust level divisions are grouped into several sets of three, with one LED set associated with each of the three sections. As a result, the dust level display 206 of the exemplary embodiment has only 15 sections, but only 6 different settings (ie, 0 section, 3 sections, 6 sections, 9 sections, 12 sections, or 15 sections). In an exemplary embodiment, the dust level display 206 incorporates a color LED to aid in recognizing as follows:
Level 1-The first category lights up in green with 100% brightness, and the remaining categories light up in white with 50% brightness.
Level 2-The first two categories are 100% bright and amber, and the remaining 50% brightness is white.
Level 3-The first three categories are 100% bright and amber, and the remaining 50% brightness is white.
Level 4-The first four categories are 100% bright and red, and the remaining 50% brightness is white.
Level 5-5 All 5 categories are lit red with 100% brightness.

In this embodiment, the blower speed display element 18b implements the dual function of displaying the current blower speed and accepting the touch sensor input so that the blower speed can be manually set by the operator. Like the dust level display, the blower speed display includes a plurality of separate display elements 18 having two LEDs that can be selectively lit to represent the "current" or "on" state. Unlike dust level displays, blower speed displays are also touch sensor arrays that can be used by the operator to manually select the blower speed. When the blower speed is displayed, the number of blower speed input display elements that are lit in the "on" state is selected to represent the blower speed, and the other blower speed input display elements are lit in the "current" state. Allows the operator to see the available blower speed options, compare the ratio of the "on" category to the "current" category, and understand the current blower speed. In an exemplary embodiment, the "current" state may be created by statically lighting a white LED with 50% brightness. The "on" state may be provided by statically lighting the blue LED at 100% brightness. To provide a touch sensor, each blower speed indicator element 18b includes a relevant capacitive coating compartment. As described above, the control subsystem 60 monitors the partitioning of the capacitive coating to determine when the touch occurred. Upon touch, the control subsystem 60 may adjust the blower speed to match the selected setting.

In an exemplary embodiment, the power input display element 208 is lit red with 100% luminance when in the "current" state and white with 100% luminance when in the "on" state. The "smart" mode input display element 210 is lit white with 50% brightness when in the "current" state and blue with 100% brightness when in the "on" state. The "turbo" mode input display element 212 is lit white with 50% luminance when in the "current" state and blue with 100% luminance when in the "on" state. The "night" mode input display element 214 is lit white with 50% luminance when in the "current" state and red with 50% luminance when in the "on" state.

As described above, the control system 12 of the exemplary embodiment executes the control scheme in four different modes of operation:
Smart mode (or automatic mode), "manual" mode, "turbo" mode, and "night" mode. The control method will be described with reference to FIG. During the "smart" operating mode, the control subsystem 60 evaluates the dust sensor reading and determines the blower speed based on the reading. This allows the ATS 10 to adapt to varying levels of aerial dust in the environment. In this mode the operator has the option to enter turbo mode, night mode, manual mode, or ATS power outage. As such, the turbo mode input display element, the night mode input display element, the different blower speed input display element, and the power input display element are lit. The turbo mode input display element and the night mode input display element are lit in the "current" state. The smart mode input display element and the power input display element are lit in the "on" state. Touching the smart mode input display element while the system is already operating in smart mode puts the system into manual operating mode. The blower speed input display element is lit to indicate the current blower speed and available manual adjustment options according to the lighting method described above. In addition, in smart mode, the dust level information type display element is lit to indicate a real-time dust level according to the lighting method described above. In smart mode, the filter life display is lit for a specific amount of time each time the user interacts with the ATS10. For example, the control subsystem 60 may turn on the filter life display for 15 seconds each time the operator interacts with the touch sensor in the display 16. In addition, the filter life display can be lit whenever and while attention is needed to the filter (eg, any one of the filters needs to be cleaned or replaced).

The control subsystem enters manual mode (or direct mode) when the operator touches the blower speed input display element 18b. Once in manual mode, the control subsystem 60 operates the blower 56 at a speed of the operator's choice. In this mode the operator has the option to enter turbo mode, night mode, smart mode, blower speed adjustment, or ATS power outage. As such, the turbo mode input display element, night mode input display element, smart mode input display element, different blower speed input display element, and power input display element are lit. The smart mode input display element, the turbo mode input display element, and the night mode input display element are lit in the "current" state. The power input display element is lit in the "on" state. The blower speed input display element is lit to indicate the current blower speed and available manual adjustment options according to the lighting method described above. In addition, the dust level information type display element is lit to indicate the real-time dust level according to the above lighting method. In this mode, the filter life display is lit for a specific amount of time each time the user interacts with the ATS10. For example, the control subsystem 60 may turn on the filter life display for 15 seconds each time the operator interacts with the touch sensor of the display 16. In addition, the filter life display can be lit whenever and while attention is needed to the filter (eg, any one of the filters needs to be cleaned or replaced).

When the operator touches the turbo mode input display element, the turbo mode is entered. Once in turbo mode, the control subsystem 60 activates the blower 56 at a preset time (eg, 30 minutes), a maximum speed setting (or some other predetermined speed setting), and then the previous operation. Automatically return to mode. Turbo mode may be interrupted by the touch of a button, in which case the system may transition from turbo mode before the preset time has expired. In this mode, the operator can touch the smart mode input display element to enter smart mode, touch the blower speed input display element to adjust the blower speed and enter manual mode, or touch the power input display element. And have the option of turning off the power of the ATS. In addition, the operator has the option to touch the turbo mode input display element to immediately return the system to its previous setting. As such, the turbo mode input display element, the smart mode input display element, the different blower speed input display element, and the power input display element are lit. The turbo mode input display element and the power input display element are lit in the "on" state, while the smart mode input display element is lit in the "current" state. The blower speed input display element is lit to indicate the current blower speed and available manual adjustment options according to the lighting method described above. In addition, the dust level information type display element is lit to indicate the real-time dust level according to the above lighting method. In this mode, the filter life display is lit for a specific amount of time each time the user interacts with the ATS10. For example, the control subsystem 60 may turn on the filter life display for 15 seconds each time the operator interacts with the touch sensor of the display 16. In addition, the filter life display can be lit for as long as the filter needs attention.

When the operator touches the night mode input display element, the night mode is entered. Once in night mode, the control subsystem 60 continues to operate the ATS 10 in the same mode, but the display content is reduced to minimize light emission. In this mode, the operator either disables the night mode by touching the night mode input display element (ie, reactivates the display according to the current operating mode) or touches the power input display element. It has the option of turning off the power of the ATS. In night mode, only the night mode input display element and the power input display element are lit, both of which are lit in the "on" state. In one alternative embodiment, the control subsystem 60 may be configured to re-operate (whole or part) the display 16 when the operator is in close proximity to the display 16. For example, the control subsystem 60 senses the proximity of the operator using the capacitive touch sensor array 64 and uses it as a trigger to light all of the input display elements 18b so that the operator can set all the control elements. You may have it. If the operator does not enter a command within a certain time (eg, 15 seconds) after the display 16 is re-enabled, the control subsystem 60 may return the display 16 to night mode.

If the ATS 10 is connected to a power source but not turned on, the control subsystem 60 turns on the power input display element in the "current" state. This allows the operator to see the power control element. Once the power button is touched, the control subsystem 60 can boot the system in smart mode or manual mode. When activated in smart mode, the control subsystem 60 takes a dust sensor reading, measures an appropriate blower speed based on the dust sensor reading, and then activates the blower at the measured speed. All of these steps are done automatically without the need for operator input. When activated in manual mode, the control subsystem 60 will not do so unless instructed to activate the blower 56 by an operator's input, eg, an operator's touch on one of the blower speed input display elements 18b. ..

The above control method is merely exemplary. The control system 12 may execute various alternative control methods. For example, an alternative control method is shown in FIG. This alternative control method is basically the same as the above control method, but as described here. To perform this control scheme, the display may include an additional mode control button associated with the "manual" mode (shown as "user" in FIG. 14). In this control method, the operator needs to make a transition between different operation modes by using the mode control button. For example, the operator must touch the "user" mode input display element to enter manual activation mode (rather than simply touching the blower speed input display element). Once in manual mode, the operator can control the blower speed by touching the desired blower speed input display element. As another example of this control scheme, the operator can exit turbo mode only by touching the turbo mode input display element or by allowing a preset time to elapse. Similarly, the operator can exit night mode only by touching the night mode input display element.

Another alternative control scheme is shown in FIG. In the present embodiment, the control method is basically the same as the first control method described above, but as described here. To perform this control scheme, the display includes an additional mode control button associated with the "option" mode (indicated as "option" in FIG. 15). When you turn on the system, it boots in "smart" mode and the blower speed is automatically set based on the input from the dust sensor. You must touch the "Options" mode button to provide additional control options. In "smart" mode, the power input display element is lit in the "on" state, the smart mode input display element is lit in the "on" state, the option mode input display element is lit in the "current" state, and the dust level display. Is lit. The turbo mode input display element, night mode input display element, and blower speed display are off. In smart mode, the operator can touch the power input display element to turn off the power of the system, or touch the option mode input display element to enter the option mode.

Once in "option" mode, the power input display element is lit in the "on" state, the smart mode input display element is lit in the "on" state, and the option mode input display element is lit in the "on" state. The dust level display is lit and the blower speed display is lit. In addition, the turbo mode input display element and the night mode input display element are lit in the "current" state. In option mode, the operator can touch the power input display element to turn off the system, touch the smart mode input display element to return to smart mode, or touch the option mode input display element to smart mode. Return to, touch the turbo mode input display element to enter turbo mode, touch the night mode input display element to enter night mode, or touch the blower speed input display element to select the blower speed. You can enter or enter manual mode. If no button is touched within a given time (eg 60 seconds), the system may automatically return to smart mode.

Once in "manual" mode, the power input display element is lit in the "on" state, the option mode input display element is lit in the "current" state, the dust level display is lit, and the blower speed display is lit. .. In addition, the smart mode input display element, the turbo mode input display element, and the night mode input display element are off. In manual mode, the operator can touch the power input display element to turn off the system, touch the option mode input display element to enter "manual option" mode, or touch the blower speed input display element. And you can select the blower speed. While the system remains in manual mode, it keeps the blower running at the speed of the operator's choice.

Once in "manual option" mode, the power input display element and option mode input display element are lit in the "on" state, and the dust level display and blower speed display are lit. In addition, the smart mode input display element, the turbo mode input display element, and the night mode input display element are lit in the "current" state. In manual option mode, the operator can touch the power input display element to turn off the system, touch the smart mode input display element to return to smart mode, or touch the option mode input display element to manually. Return to mode, touch the turbo mode input display element to enter turbo mode, touch the night mode input display element to enter night mode, or touch the blower speed input display element to select the blower speed. , You can return to manual mode. If no button is touched within a given time (eg 60 seconds), the system may automatically return to smart mode. If no button is touched within a given time (eg 60 seconds), the system may automatically return to manual mode.

Once in turbo mode, the control subsystem activates the blower at a preset time (eg 30 minutes), maximum speed setting (or some other predetermined speed setting), and then to the previous operating mode. Return automatically. Turbo mode may also be interrupted by the touch of a button, in which case the system may transition from turbo mode before the end of the preset time. The turbo mode input display element and the power input display element are lit in the "on" state. The blower speed display and dust level display are also lit. In addition, the smart mode input display element, the option mode input display element, and the night mode input display element are off. In this mode, the operator has the option of touching the turbo mode input display element to return to the previous operating mode, or touching the power input display element to turn off the power of the ATS.

Once in "night" mode, the control subsystem continues to operate the ATS in the same mode of operation, but the display content is reduced to minimize light emission. In night mode, the night mode input display element is lit in the "current" state and the power input display element is lit in the "on" state. The remaining display elements are off. In this mode, the operator either disables the night mode by touching the night mode input display element (ie, reactivates the display according to the current operating mode) or touches the power input display element. It has the option of turning off the power of the ATS.

[D. Front cover]

As described above, the ATS 10 includes a removable front cover 32 that closes the front of the ATS 10 that covers the filters 100, 102, and 104, as well as an electronic component module 14, and a blower 56. The front cover 32 of the exemplary embodiment defines the central inlet 106a and is offset from the ATS housing 110 so that they together define the side inlets 106b-c. The entrance side edge portion 98 may be fitted into the central entrance 106a. In an exemplary embodiment, the front cover 32 is a convex body that creates a relatively large headspace between the rear surface of the front cover 32 and the attached filter. This allows air to enter the ATS 10 more freely through the central inlet 106a.

In this embodiment, the front cover 32 also forms the interface surface of the "dead front" display 16. As such, the front cover 32 of this embodiment is at least translucent in the area of the LED array 62, the optical duct array 72, and the electronic component modules 14 above the screens 74a and 74b (eg, visible light). Not completely transparent or completely opaque). The front cover 32 may be made from a translucent polymer (eg, a molded thermoplastic resin) having a paint or film coating that provides the desired translucency. In one embodiment, the front cover 32 is covered by the in-mold membrane method. Careful control of the paint or film coating applied to the front cover 32 may be required to make the appearance of the "dead front" display more appropriate. Alternatively, the front cover 32 may be manufactured from a translucent material such as a molded translucent thermoplastic resin.

In an exemplary embodiment, the front cover 32 is configured to allow one-handed removal and attachment. The front cover 32 includes a mechanical mounting portion at the top and a pair of magnetic mounting portions at the bottom. In an exemplary embodiment, the mechanical attachment is aligned with the electronic component module 14. This helps ensure the correct alignment between the front cover 32 and the lower components of the display 16, which helps ensure the correct appearance and operation of the "dead front" display. Can be done. The mechanical attachment is aligned with the electronic component module 14 in the exemplary embodiment, but it may be aligned with the other structure in the alternative embodiment.

Referring here to FIGS. 19A and 19B, the mechanical mounting portion of the exemplary embodiment includes an edge portion 36 extending from the front cover 32 and is configured to stay in the electronic component module 14. In an exemplary embodiment, the edge 36 extends approximately across the width of the electronic component module 14, but may include a gap 37 (see FIG. 2) aligned with the dust sensor inlet 82. The edges 36 of this embodiment are oriented at an angle that allows the edges 36 to remain in the electronic component module 14 as the front cover 32 is lowered to the correct position. Thereby, the front cover 32 can be removed from the ATS housing 110 by sliding it upward with respect to the ATS housing 110. This upward slide movement not only removes the edge 36 from the electronic component module 14, but also at the same time removes the magnet 90 from the mounting plate 92 in the ATS housing 110 (as described below), thereby removing it. Make it easy. The size, shape, and configuration of the edge portion 36 may vary depending on the application. In an alternative embodiment, the edges may be replaced by other essentially any convex or concave structure capable of engaging the electronic component module 14.

In this embodiment, the front cover 32 includes two magnetic mounting portions near both sides of the bottom of the front cover 32. Each magnetic attachment includes a magnet 90 attached to the front cover 32 and a magnetically attractive plate 92 attached to the ATS housing 110 (see FIGS. 20A and 20B). The magnet 90 may be a disk-shaped rare earth magnet attached to a corresponding embedded portion 94 projecting from the rear of the front cover 32. The plate 92 is sized and shaped such that the magnet 90 is substantially removed from the plate 92 when the front cover 32 is slid upwards sufficiently far away from the edge 36 from the electronic component module 14. It may be. The number, size, shape, and configuration of magnets and plates may vary from application to application, if desired. For example, stronger magnets or more magnetic attachments may be used to increase the force required to remove the front cover 32.

In use, the front cover 32 may be removed and attached in various ways. One option for removing the front cover 32 is shown in FIG. 17A. In this option, the front cover 32 is slid upwards relative to the ATS housing 110 long enough for the edge 36 to separate from the electronic module 14, and then the top of the front cover 32 is magnetically mounted. Is tilted away from the ATS housing 110 to overcome any residual magnetic attraction. The front cover may be attached using basically the reverse method. Another option for removing the filter is shown in FIG. 17B. In this option, the operator extends his hand down and pulls the bottom of the front cover 32 away from the ATS housing 110 until the magnet 90 comes off the plate 92. The operator then lifts the front cover 32 a distance sufficient to separate the edge 36 from the electronic component module 14. The front cover 32 covers the electronic component module 14 with the top of the front cover 32 and then rocks the bottom of the front cover 32 towards the ATS housing 110 until the magnet 90 engages the plate 92. , May be attached.

The front cover 32 may include an interlock magnet (not shown) that allows the control subsystem 60 to recognize when the front cover 32 was attached and when it was removed. The interlock magnet may be located closer to the top of the front cover 32, which may be sensed by a Hall effect or other magnetic field sensor built into the electronic component module 14. As an alternative to using a separate interlock magnet, the ATS 10 recognizes the presence or absence of the front cover 32 based on one of the magnets 90 used to attach the front cover 32 to the ATS housing 110. It may include a Hall effect sensor (or other magnetic field sensor) arranged to allow it to do so.

If desired, the electronic module 14 may include an LED or other light source that may serve to provide lighting that is visible through the central inlet opening 106a and / or from the side of the front cover 32. This lighting may be provided as accent lighting or may have a functional purpose. For example, the control system 12 may or may not provide a blue light when the ATS 10 is operating properly and does not require maintenance, and may provide a red light when operator intervention is required. You may. This can happen when the filter needs to be changed or cleaned or when there is a system error. The red light may flash when a particular urgent problem is present.

As mentioned above, the front cover 32 incorporates an appropriate level of translucency to generate the "dead front" display 16. As an alternative, the "dead front" display may be generated by a translucent component placed under the front cover 32, such as a separate panel placed on the electronic component module 14. In such embodiments, the front cover 32 may be transparent or sufficiently translucent so that the underlying "dead front" display can be seen through the front cover 32.

[E. Mobility features]
In an exemplary embodiment, the ATS 10 may be configured to interface with one of a plurality of interchangeable bases 40. In an exemplary embodiment, the bases 40, 40', and 40 "are secured to the ATS housing 110 using screws or other fasteners. The number and location of fasteners may vary from application to application. As an alternative or addition to, the ATS housing 110 and the bases 40, 40', and 40'may be provided with snap features that allow the desired base to be snap-fitted into the ATS 10.

Each different base 40 may provide a different structure for receiving the power cord 42 and / or a different structure for supporting the ATS 10. ATS10s with three alternative bases 40, 40', and 40' are shown in FIGS. 21 and 22. In general, the base 40 includes a bobbin 44 for manually winding the power cord 42 and a plurality of fixed foot portions 46. The base 40'has a bobbin 44'for manually winding the power cord 42'and a plurality of casters 46'; the base 40'has a cord storage with an automatic take-up reel (not shown). Includes assembly 45, including a combination of fixed foot 46 "and rollers 47". The illustration shows one embodiment of a bobbin extending across a portion of the ATS housing 110, wherein the term "bobbin" is any individual feature or any individual feature provided as a structure capable of winding the power cord 42 around. Intended to include a combination of features.

In an exemplary embodiment, the ATS 10 also includes a handle 48 located at the top rear of the ATS housing 110. The handle 48 of the present embodiment is basically extended to the full width of the ATS 10 and enables the ATS 10 to be grasped at the center with one hand or at both sides with both hands. In this embodiment, the handle 48 has a relatively deep central pocket deep enough to accommodate the operator's fingers up to approximately two knuckles and to accommodate the operator's fingers up to approximately the first knuckle. It may include a relatively shallow side pocket of sufficient depth. The handle 48 may be an integral component that is secured to the ATS housing 110, for example by fasteners, or it may be integrally formed with other parts of the ATS housing 110.

With respect to the base 40, the handle 48 can be used to lift the ATS 10 as it is moved from place to place. With respect to the base 40', the handle can be used to grab the ATS as it is rolled from place to place on casters 46'. With respect to the base 40 ", the handle 48" can be used to tilt the ATS 10 forward on the rollers 47 "and roll the ATS 10 from place to place.

[F. Filter cage assembly]
As described above, the ATS 10 includes a pre-filter 100, a particle filter 102, and a carbon filter 104 that are detachably fitted into the filter housing 112. The system includes a filter cage assembly 50 that facilitates quick and secure installation and removal of the filter. In an exemplary embodiment, the filter cage assembly 50 includes a fastener 52 and a pair of clips 54 built into the frame of the particle filter 102, as well as a locking protrusion 126 built into the ATS housing 110. Since the pre-filter is fixed to the particle filter 102 and the particle filter 102 covers the carbon filter 104, the filter cage assembly 50 effectively fixes all three filters 100, 102, and 104. In an exemplary embodiment, the clip 54 is configured to pull the particle filter 102 tightly into the filter housing 112 as it is closed. As a result, the end face seal 118 of the particle filter 102 is pressed against the shoulder portion 114 to facilitate airtight sealing.

Here, referring to FIG. 29B, the fastening portion 52 is arranged at the center of the bottom portion of the frame portion of the particle filter 102. The fastening portion 52 of this embodiment is integrally molded with the frame portion of the particle filter 102, but it may be formed separately and attached to the frame portion instead. The fastener 52 of the exemplary embodiment has a quadrant cross section that can be easily attached and detached to and from the corresponding cavity 120 in the filter housing 112. The number, size, shape, and configuration of the fastener 52 and the cavity 120 may vary depending on the application, if desired. For example, the fastening portion 52 and the cavity 120 may be reversed in position so that the fastening portion extends from the filter housing 112 and the cavity is defined by the particle filter 102.

Perhaps best shown in FIGS. 29A and 29B, the clip 54 is rotatably attached to both sides of the frame of the particle filter 102. Each clip 54 may include a handle 122 and a hook 124. The handle 122 is configured to provide a structure that can be used by the operator to rotate the clip 54. The hook 124 is configured to engage the locking protrusion 126 as the clip 54 is rotated to the closed position. The hook 124 and the locking protrusion 126 are configured such that there is a short distance of interference between the two as the clip 54 approaches the closed position. This creates a snap fit that helps secure the clip 54 in the closed position. By further moving towards the closed position, the hook 124 bends while creating resistance to further movement towards the closed position. As the clip 54 continues towards the closed position, the hook 124 begins to cross the area of interference and return to its original unbent state. This pushes the clip 54 the remaining minutes into the closed position. In an exemplary embodiment, the position and configuration of the hook 124 relative to the axis of rotation position is selected such that the clip 54 provides a cam-like function of pulling the particle filter 102 into the filter housing 112 as the clip 54 is closed. The operation of the clip 54 is shown in FIGS. 30A to 30D. FIG. 30A shows the clip 54 in the open position. At this position, the hook 124 is disengaged from the locking protrusion 126. FIG. 30B shows a clip 54 in a partially closed position. As can be seen, the hook 124 has just moved to engage the locking protrusion 126. At this position, the particle filter 102 is partially retracted into the filter housing 112, as can be seen by comparison with the reference line R. FIG. 30C shows the clip 54 further moved toward the closed position. In this figure, the hook 124 engages with the locking protrusion 126 and begins to bend outward from the locking protrusion 126 due to interference between the two. As can be seen, the particle filter 102 is further drawn into the filter housing 112. FIG. 30D shows the clip 54 in the closed position. At this position, the hook 124 is fully engaged with the locking protrusion 126 beyond the area of interference. The particle filter 102 has just been fully drawn into the filter housing 112.

The removal of the particle filter 102 is described in relation to FIGS. 28A-D. In the first embodiment, the front cover 32 and the front filter 100 are removed so that the particle filter 102 can be handled (see FIG. 28A). In the exemplary embodiment, it is not necessary to remove the pre-filter 100 from the particle filter 102. In the following example, each of the clips 54 is rotated from the closed to the open position (see FIG. 28B). As a result, the hook 124 is disengaged from the locking protrusion 126 of the filter housing 112. The following example shows that the upper part of the particle filter 102 is tilted away from the filter housing 112 (see FIG. 28C). The following example shows that the filter 102 is lifted from the filter housing 112 and the fastener 52 is removed from the cavity 120 (see FIG. 28D). The particle filter 102 can be attached using basically the reverse method.

Clip designs and configurations can vary from application to application. Alternative clips 54'and 54 "are shown in FIGS. 31A-D and 32A-D. In both of these alternative embodiments, the filter cage assembly is for locking the clips 54', 54" in the closed position. Further including pins 128', 128'. Locking pins 128', 128' project from the particle filter 102, or may project from the filter housing 112 if desired. The alternative clip 54'includes a tooth portion 130'protruding from the outer edge of the clip 54'. The tooth portion 130'is configured to engage the corresponding recess 132'in the locking pin 128'when the clip 54'is in the closed position. The tooth portion 130'and the locking pin 128' snap-lock the clip 54'in the closed position together. The operation of the clip 54'is shown with reference to FIGS. 31A to 31D. FIG. 31A shows the clip 54'in the open position. At this position, the hook 124'is detached from the locking protrusion 126'. FIG. 31B shows a clip 54'in a partially closed position. As can be seen, the hook 124'move to engage the locking protrusion 126'. At this position, the particle filter 102 is partially retracted into the filter housing 112, as can be seen by comparison with the reference line R. FIG. 31C shows the clip 54'moved further toward the closed position. In this figure, the hook 124'further engages the locking protrusion 126', further pulling the filter 102 into the filter housing 112. FIG. 31D shows the clip 54'in the closed position. At this position, the tooth portion 130'is fitted into the recess 132' and the particle filter 102 is fully retracted into the filter housing 112. The interrelationship between the tooth portion 130'and the locking pin 128'helps secure the clip 54'in the closed position.

The alternative clip 54 "is similar to the clip 54'. In this embodiment, the clip 54" includes a set of contours that interact with the locking pin 128 "to control the movement and feel of the clip 54". More specifically, the clip 54 "includes a stop 134" and a receiving 136 "that are configured to engage the locking pin 128" when the clip 54 "is in the open or closed position. The 134 "is configured to engage the locking protrusion 128" when the clip 54 "is fully open. The stop 134 "helps limit the range of movement of the clip 54". The receiving portion 136 "is configured to interlock with the locking pin 128" when the clip 54 "is fully closed, creating a snap-fitting interaction as the clip 54" is closed or opened. As described above, the leading edge portion of the receiving portion 136 "may be raised. Here, the operation of the clip 54" will be described with reference to FIGS. 32A to 32D. FIG. 32A shows the clip 54 "in the open position. At this position, the hook 124" is disengaged from the locking protrusion 126 "and the locking portion 134" is engaged with the locking pin 128 ". FIG. 32B shows a clip 54 ”in a partially closed position. The hook 124 "has just moved to engage the locking protrusion 126". At this position, the particle filter 102 is partially retracted into the filter housing 112, as can be seen by comparison with the reference line R. FIG. 32C shows the clip 54 "moved further towards the closed position. In this figure, the hook 124" further engages the locking protrusion 126 "and further engages the filter 102 to the filter housing 112. Also, the leading edge of the receiving portion 136 "has just begun to engage the locking pin 128". FIG. 32D shows the clip 54 "in the closed position. At this position, the locking pin 128 "and the receiving portion 136" are fully engaged and the particle filter 102 is sufficiently retracted into the filter housing 112. The relationship between the locking pin 128 "and the receiving portion 136" helps secure the clip 54'in the closed position.

[G. Alternative Embodiment]
The present invention can be implemented in a wide variety of alternative embodiments. For example, an alternative embodiment is shown in FIGS. 33A-53D. Except for the scope described below or the scope shown in the accompanying drawings, this alternative embodiment is generally the same as the embodiments shown in FIGS. 1A-20B as described above. For ease of disclosure, this alternative embodiment is described with the same reference numerals as those used in connection with ATS10, except that they are prefixed with the number "4". For example, the alternative ATS is indicated by reference numeral 410 (similar to ATS10) and the ATS housing of the alternative ATS is indicated by reference numeral 4110 (similar to ATS housing 110).

Referring here to FIGS. 33A, 33B, and 34, the ATS410 generally includes a housing assembly that houses a control system 412, a blower 456, a pre-filter 4100, a particle filter 4102, and an activated carbon filter 4104. The ATS 410 includes untreated air inlets 4106a-c in the front capable of drawing untreated air into the system and an air outlet 4108 in the rear capable of returning treated air to the environment (see FIG. 44). In operation, the control system 412 activates the blower 456 to draw untreated air into the ATS410 through inlets 4106a-c, continuously passing untreated air through the three filters 4100, 4102, and 4104, and then processing. The finished air is discharged through the outlet 4108. The sizes, shapes, and configurations of the inlets, outlets, and internal channels may vary from application to application, if desired.

Referring again to FIG. 34, the housing assembly generally includes a housing body 4110, a filter housing 4112, and an upper housing 4113. The housing body 4110 first forms the rear, side, and bottom of the ATS 410. Like the ATS 10, the filter housing 4112 is attached to the housing body 4110 to close the front of the ATS 410 and provide a receiving portion for the particle filter 4102 and the carbon filter 4104. Perhaps best shown in FIG. 49, the upper housing 4113 is attached to the rear side of the filter housing 4112, for example by screws (not shown). The upper housing 4113 includes an integral handle 448. In this embodiment, the handle 448 includes a central portion that can be gripped with one hand and a pair of side portions that can be gripped with both hands. In an exemplary embodiment, the housing body 4110 includes a cord winding 444 (or bobbin) for manually winding a power cord (not shown) (see FIG. 33B). In this embodiment, the cord winding 444 includes a pair of finger portions 445 that are spaced apart from each other on both sides of the power cord inlet 447. The size, shape, and configuration of the finger portion 445 may vary, for example, depending on the characteristics of the power cord. As shown, the cord winding 444 may be disposed in the recess of the housing body 4110 so that it does not project and thus does not enlarge the contour of the ATS 410.

The ATS 410 includes a removable front cover 432 that closes the front of the ATS 410 that covers the display 416 and filters 4100, 4102, and 4104. As seen in various figures such as FIGS. 33a, 44, and 46, the front cover 432 defines the central inlet 4106a and is spaced from the filter housing 4112 so that the front cover 432 and the filter housing 4112 are sideways. The part entrances 4106b to c will be co-defined. The exemplary front cover 432 is manufactured from an opaque plastic material, for example, by injection molding. Alternatively, the front cover 432 may be manufactured from a wide range of alternative materials. In this embodiment, the front cover 432 includes a window portion 433 that covers the display 416. The window portion 433 is fitted into the corresponding opening 435 defined in the front cover 432. To hide the unlit display element, the window portion 433 of this embodiment is at least translucent in one or more areas above the display element 418. The window portion 433 may be manufactured from a translucent polymer (eg, a molded thermoplastic resin) having a paint or film coating that provides the desired translucency. In one embodiment, the window portion 433 is covered by the in-mold membrane method. Careful control of the paint or film coating applied to the window 433 may be required to more easily optimize the appearance of the "dead front" display. Alternatively, the window portion 433 may be manufactured from a translucent material such as a molded translucent thermoplastic resin.

In an exemplary embodiment, the front cover 432 is configured to allow one-handed removal and attachment. The front cover 432 includes a mechanical mounting portion at the top and a pair of magnetic mounting portions at the bottom. Referring here to FIGS. 45A, 45B, and 46, the mechanical mounting portion of the exemplary embodiment includes a fastening portion 436 (or edge portion) that extends from the front cover 432 and extends from the electronic component module 414. It is configured to fit into the receiving portion 437 or the structure surrounding the electronic component module 414. The fastener 436 may be manufactured separately and attached to the front cover 432 (see FIG. 46), or it may be integrally formed with the front cover 432 (not shown). The fastening portion 436 of the present embodiment is oriented at an angle that allows the fastening portion 436 to be held in the receiving portion 437 as the front cover 32 is closed. Thereby, the front cover 432 can be removed from the ATS housing 4110 by sliding it upward with respect to the ATS housing 4110. This upward slide movement not only allows the fastener 436 to be removed from the receiving portion 437, but at the same time allows the magnet 490 to be removed from the mounting plate 492 in the ATS housing 4110 (as described below), thereby being easy to remove. And. The size, shape, and configuration of the fastener 436 may vary depending on the application. In an alternative embodiment, the fastener 436 is essentially any other convex or concave structure capable of engaging the receiver 437, or any other similar structure in or around the electronic component module 414. It may be replaced by.

The front cover 432 of the present embodiment includes two magnetic mounting positions near both sides of the bottom of the front cover 432. Each magnetic attachment includes a magnet 490 attached to the front cover 432 and a magnetically attractive plate 492 attached to the ATS housing 4110 (see FIG. 48). The magnet 490 may be a disk-shaped rare earth magnet attached to a corresponding embedded portion 494 protruding from the rear of the front cover 432. In this embodiment, the plate 492 has two functions: (i) a function of providing a magnetically attractive structure to the magnet 490 and (ii) a function of rotatably supporting the roller 447. It is configured to carry out. In this embodiment, each plate 492 is generally L-shaped and has a first leg 493 arranged to receive a magnet 490 and a second leg 495 rotatably supporting the roller 447. The first leg 493 and the second leg 495 are generally flat, but may include ridges or other contours to increase strength or to fit adjacent components of the ATS 410. .. The first leg 493 includes a pair of mounting tabs 491 that extend rearward to allow the plate 492 to be attached to the housing 4110, for example by screws (not shown). The second leg 495 defines a circular opening 497 configured to rotatably receive the mandrel (or shaft) of the roller 447. For use, the two plates 492 are fitted with both ends of the shaft or mandrel of the roller 447. In this embodiment, the plate 492 is punched from the sheet material and configured for both left and right, so that the same plate 492 can be used on either side of the ATS 410 by simply turning the plate 180 degrees. For example, the mounting tabs 491 may be centered in the vertical direction, and each tab 491 may be spaced at the same distance from the corresponding end in the first leg 493. Further, the circular opening 497 faces the second leg portion 495 and may exist vertically.

In this embodiment, the control system 412 includes a capacitive sensor that allows the system to recognize when the front cover 432 was attached and when it was removed (discussed in more detail below). This eliminates the need for any interlock magnet or magnetic field sensor used to determine the presence of the front cover, as described above in connection with the ATS10.

As mentioned above, the ATS 410 includes a pre-filter 4100, a particle filter 4102, and a carbon filter 4104. Similar to the ATS10, the filter is secured in the ATS410 by a filter cage assembly 450 built into the particle filter 4102. More specifically, the filter fits the carbon filter 4104 into the carbon filter receiver in the filter housing 4112, the particle filter 4102 into the particle filter receiver in the filter housing 4112 on the carbon filter 4104, and the filter cage assembly 450. The particle filter 4102 is fixed in use and attached by attaching the pre-filter 4100 to the particle filter 4102. In this embodiment, the filter cage assembly 450 is somewhat different from the filter cage assembly 50 described above in connection with the ATS 10. In this embodiment, the bottom of the particle filter 4102 is held by a fastener 452 fitted into the cavity 4120 in the filter housing 4112, and the top is a clip 454 (or) that interlocks with a locking protrusion 4126 extending from the filter housing 4112. It is held by the hook). 52A-D illustrate a method of removing the particle filter 4102 from the ATS410. FIG. 52A shows that the particle filter 4102 is attached by a clip 454 in the closed position. FIG. 52B shows that the particle filter 4102 is attached by a clip 454 rotated to the open position. FIG. 52C shows the upper portion of the particle filter 4102 tilted away from the ATS 410. The tilting movement of the filter 4102 also removes (or mostly removes) the fastener 452 from the cavity 4120. FIG. 52D shows the particle filter 4102 removed from the ATS 410. In an exemplary embodiment, the clip 454 is configured to pull the particle filter 4102 tightly into the filter housing 4112 as it is closed. As a result, the end face seal (not shown) of the particle filter 4102 is pressed against the shoulder portion 4114 to facilitate the airtight sealing.

Here, referring to FIGS. 51A to 51C, the fastening portion 452 is arranged at the center of the bottom portion of the frame portion of the particle filter 4102. The fastening portion 452 of this embodiment is integrally formed with the frame portion of the particle filter 4102, but it may be formed separately and attached to the frame portion instead. The fastener 452 of the exemplary embodiment has a quadrant cross section that can be easily attached and detached to the corresponding cavity 4120 in the filter housing 4112. The number, size, shape, and configuration of the fastening portion 452 and the cavity 4120 may vary depending on the application, if desired.

In this embodiment, the clip 454 is rotatably attached near the upper center of the frame of the particle filter 4102. The clip 454 includes a handle 4122, a tooth portion 4130, and a hook 4124. The tooth portion 4130 is configured to engage the locking pin 4128 as the clip 454 is rotated to the closed position. More specifically, the interference between the tooth portion 4130 and the locking pin 4128 causes the clip 454 to snap lock into the closed position. Further, the hook 4124 is configured to engage the locking protrusion 4126 as the clip 454 is rotated to the closed position. In an exemplary embodiment, the positions and configurations of the hook 4124 and the locking protrusion 4126 are selected such that the clip 454 provides a cam-like function of pulling the particle filter 4102 into the filter housing 4112 as the clip 454 is closed. .. The operation of the clip 454 is shown in FIGS. 53A to 53D. FIG. 53A shows the clip 454 in the open position and the hook 4124 disengaged from the locking protrusion 4126. FIG. 53B shows the clip 454 rotated clockwise and partially in the closed position. FIG. 53C shows that the clip 454 is further rotated clockwise so that the clip 454 is at a position where the tooth portion 4130 is about to engage the locking pin 4128. Next, FIG. 53D shows the clip 454 in the closed position. As can be seen, the tooth portion 4130 crosses the locking pin 4128 and now resists the movement of the clip 454 as it exits the closed / locked position. Further, the hook 4124 has just moved to engage with the locking protrusion 4126. The interaction between the hook 4124 and the locking protrusion 4126 sufficiently draws the particle filter 4102 into the filter housing 4112.

In this embodiment, the pre-filter 4100 is fixed to the particle filter 4102 using a configuration somewhat different from that incorporated into the ATS 10. As shown in FIG. 34, the front filter frame portion 4116 includes a pair of tabs 4304 at the bottom and a pair of slotted tabs 4306 at the top. As shown in FIGS. 51A-C, the particle filter 4102 includes a pair of slotted foot portions 4300 at the bottom and a pair of finger portions 4302 at the top. The finger portion 4302 may be configured to snap lock into engagement with the slotted tab 4306. For example, the finger portion 4302 may be provided with an angle upward from the particle filter frame portion. In use, first insert the tab 4304 at the bottom of the front filter frame 4116 into the slot of the foot 4300 at the bottom of the particle filter 4102, then point the top of the front filter 4100 towards the top of the particle filter 4102. The front filter 4100 is secured to the particle filter 4102 by snap-fitting the slotted tab 4306 onto the upper finger portion 4302 of the particle filter 4102 at an inward tilt.

The ATS 410 includes a control system 412, which provides a user interface for controlling the operation of the ATS 410, displaying information and accepting input from the operator. The main function of the control system 412 is to control the operating speed of the ATS410 to process the air based on the sensed parameters or the operator's input, to track and monitor the filter usage, and to the operator the mode, motor. Notify the speed setting and filter life, and accept the operator's command. The control system 412 includes a user interface implemented as a "dead front" display 416 that displays information and accepts operator input related to system operation and maintenance. The display 416 includes a plurality of display elements 418 that are visible only when lit so as to provide a dynamic display that varies to provide information and to present control options obtained at any given time. (Compare FIGS. 40 and 41). Similar to the display 16 described above, the display 416 of the ATS 410 has an information type display element 418a lit to provide information about the state of the ATS or the characteristics to be monitored, and the operator provides input to the control system 412. It includes an input display element 418b that incorporates a touch sensor to enable it (see FIG. 41). In addition to allowing user input, the input display element 418b may also provide information about the state of the ATS, such as operating mode and blower speed. The display 416 includes a display element 418 that is essentially the same as the display 16 described above, except that the display elements 418 are arranged differently so that the display 416 uses a built-in WiFi transceiver. Includes one additional display element to indicate if is communicating with an external network.

The control subsystem 460 includes a control circuit and firmware, which activates the ATS410 and includes a capacitive touch sensor array 464, a dust sensor 480, an RFID subsystem 468, and a radio communication subsystem 470. It is configured to coordinate the collection of data from the subsystem. The various modes of operation of the system are described in more detail below. Referring to the schematic explanatory view of FIG. 36, the electronic component module 414 generally includes a distributed control device having a key application controller 510, a touch detection controller 512, an LED driver controller 514, and an RFID controller 516. The main controller 510 comprises a dust sensor 480, an RFID subsystem 468 (including RFID controller 516 and RFID antenna 518), a wireless communication subsystem 470 (including Bluetooth module 520 and WiFi module 522), and a display 416. It is connected to an electrical component (including an LED driver controller 514 and a touch detection controller 512). The main controller 510 is also coupled to the blower motor power supply 530, allowing the main controller 510 to control the blower speed and, in some applications, receive feedback from the blower motor power supply 530. The main application controller 510 also has a buzzer 524 to provide audible output, a UART header 526 for diagnostics, and a pre-programmed operation-related default value as well as filter life, usage time, counting, and. It is concatenated with a non-volatile memory such as EEPROM 528 for storing operation-related history data, such as other variables that may be used in connection with the operation of the ATS 410. The touch detection controller 512 is electrically connected to a capacitive touch key defined by a plurality of capacitive trace elements 532 and an ambient light sensor 534. In use, the touch detection controller 512 can monitor the capacitive trace element and the ambient light sensor 534 and provide touch / proximity information and ambient light information to the key application controller 510. The LED driver controller 514 is connected to the LED array 462. In operation, the LED driver controller 514 may turn on the individual LEDs in the LED array 462 according to the commands received from the key application controller 510.

The control system 412 is incorporated in the built-in electronic component module 414. Referring here to FIGS. 37-39, the electronic component module 414 of the ATS 410 generally includes a base 4150, a dust sensor cover 4152, an electronic component assembly 550, and a screen 474. In this embodiment, the base 4150 is attached to the filter housing 4112 to provide a structure to which various components of the electronic component module 414 are attached. The base 4150 includes, for example, an electronic component assembly receiving portion (not shown) that allows the electronic component assembly 550 to be attached to the underside of the base 4150 by a screw (not shown) extending through the mounting tab 552. .. The base 4150 also includes a dust sensor compartment 560 that receives the dust sensor 480 and provides a flow path to direct air to the dust sensor 480. The flow path generally includes a sensor inlet 482, a sensor tunnel 484, and a sensor outlet 486. The sensor inlet 482 may be closed by a dust sensor screen 562 to prevent the dust sensor 480 from being clogged with large particles. The dust sensor 480 may be encapsulated in a pair of rubber shell halves 488a and 488b that create a leak-proof seal around the dust sensor 480. The dust sensor cover 4152 may define a plurality of airflow openings 564 that allow air to flow out of the dust sensor compartment 560 to a location upstream of the particle filter 4102. Note that the dust sensor flow path is described for a system in which the partial vacuum created by the blower 456 draws air into the ATS410 along the dust sensor flow path. Alternatively, if the blower creates a partial vacuum at the sensor inlet 482 where the air discharged through the air outlet 4108 by the ATS 410 is larger than the air flow opening 564 in the dust sensor cover 4152, the air creates a dust sensor flow path. It may flow in the opposite direction.

The electronic component assembly 550 of the ATS410 generally includes a bottom PCB 566, an optical guide 472, and a top PCB 568 (see FIG. 39). The bottom PCB 566 may support most of the circuit and circuit components, including various controllers and LED arrays 462. The LED array may include a plurality of individual LEDs 462a that may be selectively lit at the appropriate time. Each LED 462a may include a single LED or a plurality of LEDs that provide various lighting options. In the present embodiment, each LED associated with the filter life display element may include a red LED and a green LED, and each LED associated with the TS display element, the power supply display element, and the line display element includes a white LED. Each LED associated with a blower speed display element, a turbo mode display element, a WiFi display element, and a dust sensor cloud sensor element may include a blue LED and a white LED for the first dust level display. The associated LEDs may include red LEDs, green LEDs, and yellow LEDs. Each LED associated with the second and third dust levels may include a red LED and a yellow LED, and each LED associated with the fourth and fifth dust levels may include a red LED, night mode display. Each LED associated with the element may include a red LED and a white LED. Like the ATS10, the LED array 462 may be replaced or supplemented with other types of light sources such as OLEDs, lasers, and EL light sources.

The optical guide 472 provides a mounting structure for the PCB 566 and 568 and includes a plurality of optical ducts 472a, which direct light from the LED array 462 on the bottom PCB 566 to light the display element 418 on the screen 474. Transmit through an opening in the upper PCB 568. The light duct 472a is configured to create an optical flow path from the LED 462a to the corresponding display element 418. The optical ducts 472a may be isolated from each other so as to prevent light bleeding from one LED 462a to the adjacent display element 418. The surface of the light duct 472a may be rough coated to produce diffused light.

The upper PCB 568 is attached to the upper part of the optical guide 472. The upper PCB 568 defines a plurality of optical openings 570, and the plurality of trace elements 532 function as capacitive touch sensors. In this embodiment, the upper PCB 568 includes individual light openings 570 for each display element 418 (see FIGS. 38 and 39). The size, shape, and configuration of the light aperture 570 may vary depending on the application, for example, depending on the desired light effect. As mentioned above, the control system 410 includes a plurality of capacitive touch sensors 464. The design and configuration of the capacitive touch sensor may vary depending on the application. For example, each capacitive touch sensor may include a pair of electrodes, and the touch may be recognized by monitoring the capacitance between the pair of electrodes. As another example, each capacitive touch sensor may include a single electrode and the touch may be recognized by monitoring the self-capacity of the electrodes. Referring here to FIG. 39, the trace element 532 (or a pair of trace elements) extends around each optical aperture 570 associated with the input display element 418b. More specifically, a conductive trace element 532 (or a pair of trace elements), such as a conductive copper element, is provided on the outer periphery of each optical opening 570 associated with the input display element 418b. The size, shape, region, and other aspects of the configuration of each conductive trace element 532 may vary depending on the application to provide the desired touch sensor characteristics. In addition, the upper PCB 568 may include an additional conductive trace element 532b intended to sense the user's proximity. As shown in FIG. 39, the proximity sensor trace element 532b may be a relatively large trace element extending along a significant portion of the upper PCB 568. In use, the touch detection controller 512 may monitor various conductive trace elements 532 to determine when a touch or proximity event has occurred.

In this embodiment, the control system 412 includes a single screen 474 that covers all of the display elements 418. The screen 474 is a laminated structure generally including a diffusion layer and a mask layer. The diffusion layer diffuses the light generated by the LED. The mask layer masks light to produce the desired pattern, including various opaque and translucent materials such as inks, paints, films, and other adhesive layers. In an exemplary embodiment, the mask layer is placed on the outer surface of the diffusion layer opposite the LED or other light source, but may be placed elsewhere if desired. The diffusion layer and the mask layer are part of a single laminated structure in the exemplary embodiment, but instead they may be separate components. For example, they may be manufactured separately and placed adjacent to each other during assembly of the display 416.

Here, the operation of the ATS 410 will be described with reference to FIGS. 42 and 43. FIG. 42 is an example of a display 416 showing an overview of all display elements 418, including information type display elements 418a and input display elements 418b. FIG. 43 shows a series of illustrations of displays 416a-m in different operating modes. In an exemplary embodiment, the display 416 can be in three different states when the power is turned off. When the ATS410 is unpowered or otherwise unpowered, the display shows nothing at all, as the display 416a shows. If the ATS410 is connected to a power source but not turned on and the user is not in close proximity, the display elements 618a-c are lit to display a line across the display 416, as indicated by the display 416b. To. When the ATS410 is connected to a power source but not turned on and the user is in close proximity, the display elements 618a-c and 608 are lit to display a line and a power icon, as indicated by the display 416c. Will be done.

The control system 412 may determine that the user is in close proximity by monitoring the capacitive trace element 532b. The control system 412 and the proximity trace element 532b may be configured to determine when the user is in proximity using various alternative methods. In an exemplary embodiment, the control system 412 and proximity trace element 532b are such that the user waves the user's hand onto the display 416 within about 12 inches (30.48 cm) of the window portion 433, for example, the trace element 532b. It is configured to determine that the user is in close proximity when it is within about 12 inches (30.48 cm) of. The size, shape, and configuration of the trace element 532b, and / or sensed by the trace element 532b, to increase or decrease how close the user must be in order for the system to be able to determine that the user is in close proximity. The sensitivity of the control system 412 to the changes made may be changed. The control system 412 may determine that the user is not in close proximity based on the passage of time after the display 416 receives the user input. For example, the control system 412 may reset the countdown timer each time a user input event occurs. The user input event may occur each time the user touches the touch key trace element 532 or each time the user enters close enough to the proximity trace element 532b. When the countdown timer reaches zero, the control system 412 determines that the user is not in close proximity and adjusts the display 416 accordingly. The control system 412 may then begin to continue monitoring the proximity trace element 532b to determine if the user has returned sufficiently close to the display 416. In addition, the control system 412 may also determine that the user is in close proximity when the touch key trace element 532 is touched by the user.

Once powered on, the display 416 can operate in a variety of alternative states. When the ATS410 is in manual mode and the user is in close proximity, all of the display elements are lit appropriately, as indicated by the display 416d. The display elements 618a to 618 are lit to indicate a line. The display element 608 is lit to indicate a power icon. The display element 614 is lit to indicate a night mode icon. Since the ATS 410 is not in night mode, the display element 614 is lit white. A display element 606 including a dust icon 606a and an appropriate dust level indicator 606b is lit. Since the ATS410 is not in automatic mode, the dust icon 606a is lit in white. Also, because the dust level is low enough, only a single dust level indicator 606b is lit, which is lit green. A display element 616 including a blower icon 616a and an appropriate blower speed indicator 616b is lit. Since the ATS410 is not in manual mode, the blower icon 616a is lit in blue. All of the blower speed indicators 616b are lit, the indicator representing the actual blower speed is lit in blue, and the higher available blower speeds are lit in white. The display element 612 is lit white to indicate that the ATS 410 is not in turbo mode. Filter life display elements 600, 602, 604, including the ATS icon 605, are lit. In this example, all of the filters have a remaining life and are therefore lit green. The ATS icon 605 is lit in white. Next, the display element 620 is lit to display the WiFi icon. In this example, no WiFi transfer has occurred, so the WiFi icon is lit white. If the operator is no longer in close proximity, the display 416 transitions to a degraded state, showing significantly less display elements. Referring to the display 416e, the display element 618b is lit to indicate the central portion of the line. The display element 606 is lit, including the dust icon 606a and the appropriate dust level indicator 606b. A display element 616 including a blower icon 616a and an appropriate blower speed indicator 616b is lit. In this state, only the blower speed indicator, which indicates the actual blower speed, is lit in blue. Higher blower speeds available will not light up. If any of the filters have reached the end of their life, the display will also show the filter life display elements 600, 602, 604, including the ATS icon 605. In the example shown on display 416f, the pre-filter icon 600 is lit green to indicate that it has a remaining life, and the particle filter icon 602 and the carbon filter icon 604 are lit red to indicate that they have reached the end of their life. The ATS icon is lit in white.

The operator can put the ATS 410 into automatic mode by touching the dust sensor icon 606a. When the ATS410 is in automatic mode and the user is in close proximity, all of the display elements are lit as appropriate, as the display 416g shows. The display elements 618a to 618 are lit to indicate a line. The display element 608 is lit to indicate a power icon. The display element 614 is lit in white to indicate a night mode icon. The display element 606 is lit, including the dust icon 606a and the appropriate dust level indicator 606b. Since the ATS410 is in automatic mode, the dust icon 606a is lit in blue. Also, since the dust level is at the highest display level, all of the dust level indicators 606b are lit in red. A display element 616 including a blower icon 616a and an appropriate blower speed indicator 616b is lit. Since the ATS410 is in automatic mode, the blower icon 616a is lit in white. The blower speed indicator 616b, which represents the actual blower speed, is lit in blue. In this example, the blower is operating at maximum speed, so all indicators are lit blue. The display element 612 is lit white to indicate that the ATS 410 is not in turbo mode. Filter life display elements 600, 602, 604, including the ATS icon, are lit. In this example, all of the filters have a remaining life and are therefore lit green. The ATS icon is lit in white. Next, the display element 620 is lit to display the WiFi icon. In this example, no WiFi transfer has occurred, so the WiFi icon is lit white. If the operator is no longer in close proximity, the display 416 transitions to a degraded state, showing significantly less display elements. Referring to the display 416h, the display element 618b is lit to indicate the central portion of the line. The display element 606 is lit, including the dust icon 606a (blue) and the appropriate dust level indicator 606b (red). The display element 616 is lit, including the blower icon 616a (white) and the appropriate blower speed indicator 616b (blue). Whichever of the filters has reached the end of its life, the display 416 also indicates filter life display elements 600, 602, 604, including the ATS icon 605 (see, eg, FIG. 416f).

The operator can activate the turbo mode by touching the turbo icon. When the ATS410 is in turbo mode and the user is in close proximity, all of the display elements are lit appropriately, as indicated by the display 416L. The display elements 618a to 618 are lit to indicate a line. The display element 608 is lit in white to indicate a power icon. The display element 614 is lit in white to indicate a night mode icon. The display element 606 is lit, including the dust icon 606a (white) and the appropriate dust level indicator 606b. Since the dust level is medium, the three dust level indicators are lit yellow. The display element 616 is lit, including the blower icon 616a (white) and the appropriate blower speed indicator 616b. Since the ATS410 is in turbo mode, the blower is operating at maximum speed and all indicators 616b are lit in blue. The display element 612 is lit in blue to indicate that the ATS 410 is in turbo mode. Filter life display elements 600, 602, 604, including the ATS icon 605, are lit. In this example, all of the filters have a remaining life and are therefore lit green. The ATS icon is lit in white. Next, the display element 620 is lit to display the WiFi icon. In this example, no WiFi transfer has occurred, so the WiFi icon is lit white. If the operator is no longer in close proximity, the display 416 transitions to a degraded state, showing significantly less display elements. Referring here to the display 416j, the display elements 618a and 618b are lit to indicate left and center portions of the line. The display element 606 is lit, including the dust icon 606a (white) and the appropriate dust level indicator 606b (yellow). The display element 616 is lit, including the blower icon 616a (white) and the appropriate blower speed indicator 616b (blue). The display element 612 is lit in blue to indicate that the ATS 410 is in turbo mode. When any of the filters have reached the end of their life, the display 416 also indicates filter life display elements 600, 602, and 604, including the ATS icon 605 (see, eg, display 416f).

The ATS410 can be set to night mode by touching the night mode icon. The display 416 only shows the night icon 614, which is lit in red, as shown in the display 416k, when in night mode. The control system 412 limits the maximum speed of the blower 456 when in night mode, slowing the speed at which the blower 456 transitions from one speed to another. The control system 412 may be configured to perform other features when in night mode. In this embodiment, the control system 412 may be operated in manual or automatic mode when in night mode. For example, the user may touch the night mode icon 614 while the control system 412 is in either manual or automatic mode, the control system 412 transitions to night mode, otherwise according to the existing mode. Keep the blower 456 running. The control system 412 continues to operate the blower 456 at a manually specified speed when transitioning from night mode to manual mode, unless the manually set speed is above the maximum speed threshold. In that case, the control system 412 reduces the blower speed to meet the maximum speed threshold for night mode. The control system 412 allows the automatic speed control algorithm to control the blower speed when transitioning from the automatic mode to the night mode, provided that the control system 412 allows the blower speed to exceed the maximum speed threshold. Without allowing it, the change from one blower speed to another occurs at a slower transition rate.

The ATS410 may also have the ability to connect to external applications using WiFi or other wireless communication systems. To enter the wireless communication mode, the operator can touch the WiFi icon (display element 620). While the ATS 410 attempts to establish a wireless connection, the display element 620 may be lit blue in a blinking pattern, as indicated by the display 4161. The blinking may be terminated and the display element 620 may be lit in blue, as indicated by the display 416m, while the connection is once established and at the same time the ATS410 remains in wireless communication mode. In this embodiment, wireless communication can be used in any mode of operation and the control system 412 may continue to operate the display 416 according to the existing mode of operation. With respect to the operation of the ATS 410, wireless communication may be used to transfer filter life data of different filters, speed and time of operation of the blower motor, dust sensor readings over time, etc. to a remote location. Wireless communication may also be used to send diagnostic information, including data that may allow a remote individual to evaluate the operation of the ATS 410 to determine if maintenance or repair is necessary. In addition, wireless communication may be used to update the firmware and / or any other programming or data contained within the control system 412.
