The following terms are used to describe a window air filter device that can be installed in a frame window of a building:

For example, interior and exterior and similar terms are defined for windows and buildings; internal means to the room in which the window air filter device is installed; external means to leave the room. By way of specific example, one of the window air filter devices has an interior side facing one of the rooms of the building; one of the window air filter devices has an exterior side facing away from the room and ambient air to be filtered as it enters the room contact.

Such as inside, outside, inward, outward, and the like are defined for the air filter device; such as inward, inner, and the like, indicating toward the air filter One direction of the geometric center of the device. Terms such as outward, outward, and the like mean a direction away from the geometric center of the air filter device.

The term "longitudinal" means a direction (L) along the long axis of an air filter device. When installed in a frame window, the long axis of the air filter device will be orthogonal to the direction in which the movable frame of one of the frame windows is slidable. In the case of a horizontal frame window (in which case the movable frame can be moved back and forth in a horizontal direction relative to one of the ground surfaces), the longitudinal direction of the device will be at least substantially perpendicular to the surface Align the directions. The transverse direction (T) of an air filter device is orthogonal to the longitudinal direction of the device and is at least substantially aligned with the direction in which the device is slidably movable in a movable frame mounted to one of the windows. This lateral direction can be considered as the "width" direction of the device when it is installed. The thickness direction (Th) of an air filter device is orthogonal to the longitudinal direction of the device, And is orthogonal to the lateral direction of the device. When installed in a frame window, the thickness direction of the device is at least substantially aligned with the inner-outer axis of one of the windows. In Figure 14, an exemplary air filter device mounted in a horizontal frame window displays a longitudinal direction (L), a lateral direction (T), and a thickness direction (Th).

Such as upper, lower, upward, downward, above, below, and the like are applied to one of the horizontal grid windows for air filtration. Equipment.

Disclosed herein is an electric air filter device 10 comprising: a first base unit 20 including a fan; and a second movable unit 60 including an air filter assembly, the air filter The assembly includes an air filter medium. The second movable unit 60 is reversibly slidably movable relative to the first base unit 20 between at least a first unexpanded configuration and a second deployed configuration. Device 10 is configured to self-maintain in the second deployed configuration (and also self-maintaining in any partial deployment configuration), as discussed in detail later herein. An exemplary device 10 is shown in FIG. 1 as being in a first unexpanded configuration with an internal viewing angle (ie, a viewing angle viewed in a room in which one of the windows of the device is installed), and in FIG. 2 The external viewing angle (i.e., the viewing angle viewed from outside the room in which the window of one of the devices is installed) is shown as being in a first unexpanded configuration. Apparatus 10 is shown in Figure 3 as an internal deployment view and in an external perspective in Figure 4 as a second deployment configuration.

The base unit 20 includes a lower abutment portion 36 and an upper riser portion 25 as can be seen from the internal perspective of FIG. 5, wherein the movable unit 60 is disassembled from the base unit 20. In some embodiments, portions 36 and 25 can be integral with each other, meaning They have the same composition and are simultaneously fabricated into a single piece by the same operation (for example, injection molding operation). In other embodiments, portions 36 and 25 can be fabricated separately and then attached together during the manufacture of device 10. The movable unit 60 includes an upper shroud portion 75 and a lower sleeve portion 65 as can be seen in FIG. Portions 75 and 65 may be integral with one another or may be separately fabricated and reattached together.

The base unit 20 and the movable unit 60 may each comprise a body (eg, a housing) made of, for example, molded plastic, various additional components (eg, one or more weathershield, resilient layer) ), air ducts, fittings, brakes, speed limiters, etc. can be attached to the body. As is apparent from Figures 1, 5, and 6, when the apparatus 10 is in an undeployed state, the panel portion 75 of the movable unit 60 is overlaid outwardly and surrounds the riser portion 25 of the base unit 20. When the device 10 is in this undeployed state, the sleeve portion 65 of the movable unit 60 overlies the base unit 20 on the outer side 24 of the base unit 20 and on a major portion of the lateral side 66 of the base unit 20 Support portion 36. (The sleeve portion 65 has three sides with an inner side omitted so as not to block filtered air from flowing from the fan 117 toward the filter air outlet 31, as will be appreciated by, for example, inspection view 5 and Figure 8.)

The base unit 20 and the movable unit 60 can each exhibit a longitudinal axis and a horizontal axis, and the longitudinal axis of the base unit and the longitudinal axis of the movable unit are aligned with each other to define a longitudinal axis of the electric air filter device 10 (L) ), as shown in Figure 14. In many embodiments, the direction in which the movable unit 60 is reversibly movable relative to the base unit 20 in a sliding manner is at least substantially aligned with the longitudinal axis (L) of the window air filter device, such as from FIG. And Figure 3 will be clearly visible.

When the apparatus 10 is in an unfolded state, a portion of the inner side 21 of the riser portion 25 of the base unit 20 may be exposed, as shown in FIG. 3; likewise, the exterior of the lower base portion 36 of the base unit 20 may be exposed. Side 24, as shown in Figure 4. Thus, the interior (i.e., facing the room) side of the device 10 is provided by the interior side 61 of the movable unit 60 and the wall of the interior side 21 of the base unit 20, as can be seen in Figures 1 and 3. The outer side of the device 10 (facing the outside such as the entry environment) is provided by the wall of the outer side 64 of the movable unit 60 and by the wall of the outer side 24 of the base unit 20, as can be seen in Figures 2 and 4. By.

The exterior side of device 10 may be exposed to environmental conditions such as rain, snow, hail, debris blown by the wind, and the like. Accordingly, it will be understood that in the design of apparatus 10, the outer and lateral walls of base unit 20 and movable unit 60 exposed to the environment are at least substantially solid (eg, except for one of air inlets 71, such as described later). With little or no unclosed through-holes extending therethrough, and the outer and lateral walls of the movable unit 60 overlie the outer and lateral walls of the base unit 20 outwardly, enhancing the ability of these walls to minimize To prevent or enter the device 10 such as rain or snow.

The movable unit 60 includes a filter assembly 250 for filtering air (most easily seen in Figure 10). Thus, an external air inlet (e.g., an opening) 71 is provided, such as on an upper portion of the outer face 64 of the panel portion 75 of the movable unit 60, as seen in FIG. A weather shield 72 (which may be provided, for example, by a solid layer, as exemplarily illustrated in Figures 2 and 4, or a group of louver or the like) may be external to the outside air inlet. Provide) coverage that is at least substantially Stop, for example, liquid water entering the outside air inlet. Specifically, the weather shield 72 can be shielded or closed at its upper end to, for example, prevent rainwater that moves downward from entering the outside air inlet.

The base unit 20 includes a fan 117 (as shown, for example, in the exemplary embodiment of FIG. 8) for venting external air through the outer air inlet 71 and the filter media that passes through the air filter assembly 250, and The filtered air is discharged into the chamber through the filtered air outlet 31 of the base unit 20. The filtered air outlet 31 can be located on the interior (facing the room) side 21, such as the lower abutment portion 36 of the base unit 20; if desired, a cover 32 can be provided inside the filtered air outlet 31, as in Figure 1. It is shown in the illustrative embodiment. It is therefore necessary to provide a fluidic connection between the filter assembly 250 and the fan 117; in addition, this fluid connection must allow the desired mobility of the unit 60 and unit 20 relative to each other (although the description herein provides And unit 60 moves relative to unit 20, it being understood that any unit can be moved relative to the other if desired. To accomplish this, the fan 117 and air filter assembly 250 are fluidly coupled to one another by a conduit that includes at least one reversibly expandable and collapsible section. This allows the second moveable unit to reversibly slide back and forth between the first unexpanded configuration and the second deployed configuration while maintaining a fluid connection between the fan and the air filter.

As shown in the exemplary embodiments of Figures 8 and 10, a fluid connection between the fan 117 and the filter assembly 250 can be provided by a conduit that includes an air receiving container 112 that receives the air receiving container 112. The air passing through the filter media 255 is passed through an outlet joint 113 that mates with an upstream end of one of the hollow tubes (hose) 114. The downstream end of the tube 114 can be connected to one of the inlets provided in a partition 115 The head pairing allows the air to enter the fan chamber 116 containing one of the fans 117. In some embodiments, the hollow tube 114 can reversibly expand and contract along its long axis (eg, the tube 114 can be accorded as shown in Figures 8 and 10 to aid in such deployment and contraction). ). This may allow units 60 and 20 to move relative to each other along the long axis of device 10 while retaining the fluid connection between filter assembly 250 and fan 117. (It will be understood that the above-described configurations and components are merely representative of a convenient way of providing a fluid connection; any suitable fluid connection of the retention units 20 and 60 relative to each other's mobility can be used.)

In some embodiments, one or more retaining members may be provided to maintain the tube 114 in position; such as to ensure that the tube 114 does not have unacceptable bending or kink when contracted along its long axis. In a particular embodiment, such a retaining member can take the form of an elongate retention fin that extends along at least a section, such as sleeve portion 65, and at least substantially inwardly projects into the chamber in which tube 114 is positioned. in. Three such retaining fins are depicted in the cross-sectional view of FIG. 9; two primary fins 121 and one secondary fin 122 (one of the primary fins 121 can also be seen in FIG. 6; secondary fins) Sheet 122 can also be seen in Figure 13). For example, such fins can be positioned such that they collectively circumscribe at least a portion of the length of the tube 114. This means that at least one fin is present in each of the 120 degree segments of tube 114 (when viewed along the long axis of tube 114). As is apparent from Figure 9, it is not necessary for this purpose to continuously surround the circumference of the tube 114 in an uninterrupted manner; it has been found that in many cases, the three-rib of Figure 9 The configuration is acceptable.

For example, it will be understood from FIG. 8 that in some embodiments, the air filter assembly 250 (in the view of FIG. 8, which is located directly behind the air receiving container 112), the hollow tube 114, and the fan 117 can be All are at least substantially aligned with one another in a longitudinal stack configuration. By this it is meant that the components are at least substantially aligned with one another along the longitudinal axis of the device 10. This type of configuration (as opposed to designing one such as positioning a fan inside a filter assembly) may allow the device 10 to have a very small thickness dimension (ie, an internal-external extended dimension (Th), as shown in FIG. Show). It will be appreciated that this may advantageously be such that when the device 10 is installed within a window opening, the device 10 does not protrude very far from the window and thus does not interfere with such things as screens, blinds, or the like that may be present outside the window. This property can be characterized by an aspect ratio defined as the ratio of the longitudinal length of the electric air filter device to the internal-external thickness of the electric air filter device. In various embodiments, the aspect ratio of the electrically powered air filter device (measured at a maximum thickness point of the device) may be at least about 6:1, 8 when the movable unit is in the first undeployed configuration: 1, 10:1, or 12:1.

In many embodiments, device 10 can exhibit a tapered shape when viewed along the longitudinal axis of device 10 (as is apparent in the bottom view of Figure 7). This may be provided via a base unit 20 that includes first and second lateral sides 26 (provided by the first and second side walls 38) that are tapered inwardly toward each other such that they are in close proximity to the base One of the interior sides 21 of the unit is spaced apart from one another and is spaced closer to one another at a location proximate to the exterior side 24 of the base unit, as shown in the illustrative embodiment of FIG. The movable unit 60 can similarly include first and second lateral sides 66 (provided by the first and second side walls 78) that are tapered inwardly toward each other such that they are in close proximity One of the inner sides 61 of the mobile unit is spaced apart from one another and is spaced closer to each other at a location proximate to the outer side 64 of the movable unit. In the cross-sectional view of FIG. 9, it can be seen that a tapered shape of the base unit 20 and the lateral side walls 38 and 78 of the movable unit 60 are established in this manner, and wherein the side wall 78 of the movable unit covers the base outwardly. Side wall 38 of the unit.

It will be appreciated that the tapered shape of the device 10 can be such that when the air filter device 10 is mounted in an opening in a framed window with a narrower end facing outward and a wider end facing inward (Fig. 14) A transverse wall of the device 10 will hold the jamm against one of the windows, and the other transverse wall of the device 10 will abut against one of the edges of the movable frame of the window, wherein the wide end of the tapered device On the inside side of the window opening. This configuration may make it less likely that the device 10 will be forced to shift from the opening and fall outside the window.

If desired, the device 10 can include one or more edge flanges that extend beyond the lateral edges of the body of the device 10 in a generally transverse direction for positioning on an interior surface such as one of the window legs. Internal or internal to the edge of one of the movable grids. Such features may additionally minimize the likelihood that the device 10 will be forced to shift out of the window. Thus, in some embodiments, the base unit 20 can include first and second flanges 33 that extend at least substantially laterally beyond the base unit at a location proximate one of the interior sides 21 of the base unit, respectively. First and second lateral side walls 38. The movable unit 60 can similarly include first and second flanges 63 that extend at least substantially laterally beyond the first and second portions of the movable unit at a position proximate one of the inner sides 61 of the movable unit Two lateral side walls 78. Such flanges may be fabricated separately and attached to the base unit and the body of the movable unit, respectively; or they may be integrally molded with the bodies. If it is In some embodiments, device 10 can include one or more retention strips having a first end attached to device 10 and having a attachable to a retaining device (eg, a hook) At the second end, the retaining device can be mounted on an interior wall such as one of the rooms, mounted to a portion of the sash, or the like.

The electric air filter device 10 can be mounted in an opening of a frame window, such as a horizontal frame window (meaning that the movable frame in the window can be moved in a horizontal direction in a sliding manner, as shown in FIG. An exemplary window 300). Referring to Figure 14, this can be accomplished by moving a movable grid 301 (moving to the left in the view of Figure 14) to create an opening 305 in the window that is sufficiently wide to accommodate the device 10. The device 10 can then be positioned within the opening with a lowermost surface of the lower end 28 of the base unit 20 resting against the upwardly facing surface 313 of the bottom window 315 of one of the sashes 311, and wherein one of the devices 10 is first laterally The side abuts against an inwardly facing surface 312 of the side post 317 of the sash 311. The movable unit 60 of the device 10 can then be moved upwardly in a sliding manner (along the long axis L of the device 10) until the uppermost surface of one of the upper ends 68 of the movable unit 60 abuts against the upper window of one of the sashes 311 ( One of the lintel) 316 faces down the surface 314. (The device 10 is kept in this state, such as by using a one-way brake as discussed later herein.) The movable grid 301 can then be moved in a sliding manner toward the air filter device 10 (in the view of Figure 14) Moves to the right until one of the inwardly facing faces 303 of the leading edge 302 of the movable frame 301 abuts against the second lateral side of one of the air filter devices 10. In this manner, the apparatus 10 is laterally secured between the leading edge 302 of the movable frame 301 and the side post 317; and the apparatus 10 is longitudinally secured to the bottom window 315 and the upper window 316 of the sash between. The positioning of the device 10 within the opening of the window can thus be securely held.

In some embodiments, device 10 may be provided with one or more magnetic attachment elements that may be magnetically attached to one or more complementary magnetic attachment elements that are positioned At one or more suitable locations on the window frame. Such a configuration and method are described in detail in U.S. Provisional Patent Application Serial No. xx/xxxxxx (Attorney Docket No. 76686 US002), filed on the same day as the present application, and entitled "Magnetically Attachable Window Air Filter". This is incorporated herein by reference.

To assist in positioning the device 10 firmly within a window opening 305, and/or to minimize any air leakage around the device 10, the device 10 may include an elastic layer on its plurality of surfaces (such as containing foam rubber) Or any suitable elastic compressible material). For example, an elastic layer 29 can be provided on the lower end 28 of the base unit 20, such as such that one of the major surfaces of the resilient layer 29 provides the lowermost surface of the base unit 20 previously mentioned, which abuts the lower window of the sash . Similarly, an elastic layer 69 can be provided on the upper end 68 of the movable unit 60, such as such that one of the major surfaces of the elastic layer 69 provides the uppermost surface of the movable unit 60 previously mentioned, which abuts the sash Upper window.

An elastic layer can similarly be provided on the first and second lateral sides of the device 10. As can be seen most easily in FIGS. 2 and 4, this can be achieved by combining the first and second elastic layers 67 with the first and second elastic layers 27, the elastic layer 67 being provided in the movable unit 60. At least a portion of the first and second lateral sides 66, and an elastic layer 27 is provided on at least a portion of the first and second lateral sides 26 of the base unit 20. Such an elastic layer may extend along at least a portion of the longitudinal length of the plurality of lateral sides. In some embodiments, the elastic layers 67 of the movable unit 60 can each be at least substantially along the entire longitudinal length of the movable unit 60. The extent extension includes a portion 74 of the resilient layer 67 extending downwardly along the sleeve portion 65 of the movable unit 60, as can be seen in Figures 2 and 4.

In some embodiments, the resilient layers 27 of the base unit 20 can each include a lowermost portion that is positioned proximate the lower end 28 of the base unit 20; and a portion 37 that is transverse to the abutment portion 36 of the base unit 20. One of the outermost members of side 26 extends upwardly as seen in Figures 2 and 4. Such a configuration may be such that when the movable unit 60 is in the first undeployed state, the portion 37 of the elastic layer 27 of one of the first lateral sides 26 of the base unit 20 abuts against the first lateral side 66 of one of the movable units 60 externally. The lower portion 74 of the elastic layer 67. Similar considerations apply to the second lateral wall of the base unit 20 and the movable unit 60. Such an arrangement may also provide an elastic layer at each point along the entire longitudinal length of the first and second lateral sides of the device 10 when the device 10 is in an unfolded state (whether partially or fully deployed), as shown in the figure. 3 and Figure 4 are clearly visible. This can help ensure that the entire length of the first and second lateral sides of the device 10 provides a sufficient hermetic seal between the window rim and the leading edge of the pane adjacent the first and second lateral sides, regardless of The extent to which unit 60 is deployed relative to unit 20.

The apparatus 10 can use any suitable air filter assembly 250 that includes any suitable air filter media 255 (these components are most easily seen in the interior view of Figure 10, wherein the container 112 has been omitted such that the filter assembly is visible 250). In some embodiments, the air filter assembly 250 can include an air filter media 255 (eg, a pleated air filter media as shown in FIG. 10), wherein a rigid support frame (not visible in FIG. 10) ) is installed to its perimeter. Such a type of support frame can be made of, for example, chipboard, one or more molded plastic parts, and the like. For easy access, the weather shield 72 can be self-moving The outer side 64 of the element 60 is removed, at which point a filter assembly 250 can be inserted into the filter assembly holder 111 (see Figure 10). It will be appreciated that the air receiving container 112 as discussed earlier herein and as seen in the exemplary embodiment of FIG. 8 can be conveniently positioned directly within the filter assembly holder 111 and can be attached to, for example, the holder 111 and / or to any convenient part of the movable unit 60. The weather shield 72 can be reattached (e.g., by snapping) to the outer side 64 of the movable unit 60 to securely hold the air filter assembly 250 in place. Any suitable fastener(s), clamp(s), etc. may be used as an aid to a snap attachment or in lieu of a snap attachment. In some embodiments, the weather shield 72 can be hingedly coupled to the moveable unit 60 to allow access to the filter holder without the weather shield 72 being detachable from the unit 60. In some embodiments, an air filter assembly can include a flexible frame; or the assembly can be provided by a single piece of air filter media, the piece of air filter media can be tightened by any desired The securing mechanism is attached to a suitable holder.

Filter media 255 can be any suitable filter media selected from, for example, fiberglass, fiber polymeric mesh, and the like. In some embodiments, an electrostatic charge is optionally imparted to the material(s) of filter media 255 or to the material(s) of filter media 255. In other words, electrostatically charged media can be used, which are available in many grades, and many of which provide high efficiency and low pressure drop. Thus, the filter media can be or can include an electret nonwoven web. Charges can be imparted to the filter media in a variety of ways, such as by hydrocharging, corona charging, and the like, as is known in the art. In other embodiments, the filter media is not electrostatically charged. Additional multifunctional media grade (its binding activity) Carbon or other materials used to purify the gaseous pollutants may also be incorporated into one layer of the filter media. For example, the filter media can be constructed, for example, from a non-woven fibrous media, which is formed from thermoplastics or thermosetting materials such as polypropylene, linear polyethylene (linear Polyethylene), and polyvinyl chloride. Other non-limiting materials suitable for use in the filter media include porous foams, non-woven fabrics, paper, fiberglass or the like. In some embodiments, the filter media comprises a filter media that traps dust from outdoor air, allergens (such as pollen and fungal spores), and fine-particle pollutants. The filter media can be a single layer; or it can be a multi-layered media that includes multiple layers that provide various functions (eg, it can include a primary particle filter layer, a coarse pre-filter layer, and a gas or Any or the owner of the vapor absorbing layer).

As mentioned, a fan 117 is used to break in air, pass air through the inlet 71, through the filter media 255, into and through the container 112, and then into and through the hollow tube 114. The fan also discharges the filtered air through the outlet 31. Any suitable type of fan can be used, such as an axial fan, a centrifugal fan, or a cross-flow fan. In a particular embodiment, a centrifugal fan (often referred to as a squirrel-cage fan) can be used, the fan including a major axis that coincides with the axis of rotation of the fan, the long axis being at least substantially The long axis alignment of the base unit 20 in which the fan is mounted (all as shown in Fig. 8). Using such a type of fan and mounting in this manner may allow the filter, air duct, and fan to be configured to be stacked vertically as one of the previously described configurations. Fan 117 can be driven by any suitable electric motor 118. In some embodiments, Motor 118 and any other existing electrical components (eg, sensors, switches, or the like) may be powered by an internal power source (eg, a rechargeable battery). In other embodiments, such components may be powered by an external power line that may enter the base unit 20, such as through passageway 35 (see Figure 7).

In a particular embodiment, all of the electrical components of device 10 (including fan 117, and any on/off switches, fan speed control switches, operating circuitry, sensors, lights, indicators, etc.) can be positioned in base unit 20 (eg, Attached directly or indirectly to the base unit 20). Such a configuration may make the mobile unit 60 need not include any electrical components of any kind, which may simplify the manufacture and operation of the device 10.

In some embodiments, the fan 117 can be mounted in a fan chamber 116 that is defined within the lower abutment portion 36 of the base unit 20. The ceiling of such a fan room can be provided by, for example, a partition 115, as shown in FIG. In a particular embodiment, the divider 115 can be a spacer that extends at least substantially horizontally, to which various components of the device 10 can be conveniently attached, as discussed later herein. Regardless of the particular design, the divider 115 can include a passageway through which air received by the hollow tube 114 (which can be fluidly coupled to the divider 115 via any suitable joint) can enter the fan chamber 116.

The tolerances of the various components of the controllable device 10 that are close to each other and/or attached to one another will be understood to minimize the number and/or amount of air leakage into the device 10. When mounted in a window opening, this may advantageously enable little or no outside air to bypass the filter media 255, such as passing unfiltered air through the device 10 into a building. Things. Such an arrangement may also maximize the efficiency of power usage (eg, by minimizing the amount of unfiltered room air that may enter the fan chamber 116 and inadvertently recirculate).

It will be appreciated that so tightly fitting the various components to minimize air leakage, the ability to move the units 60 and 20 back and forth relative to each other as previously described must still be retained. In particular, the tightness of the various walls (eg, the transverse walls, the inner walls, and the outer walls) of the base unit 20 and the movable unit 60 can be controlled to provide a close fit in at least a portion of the units, such as This is clearly visible in Figure 9. (Figure 9 also shows an exemplary configuration of one of the various walls of units 20 and 60 that allows the units to move in a sliding manner relative to each other without being separated from each other.) If desired, such as base unit 20 and An elastic layer (e.g., a foam weather strip) is provided between the surfaces of the moving unit 60 at a position that is most advantageous for minimizing air leakage. The presence of the divider 115 (which provides the ceiling of the fan chamber 116) will also be understood (as well as the use of tight tolerances on any item that passes through the divider 115 (e.g., one of the sliders as described later herein). It can help ensure that even if unfiltered air can enter an upper portion of the device 10, such air can not easily enter the fan chamber 116.

As mentioned, during installation of the device 10 into an opening in a window, the device 10 is placed into the opening, for example, with the lower end of the base unit 20 resting against the window sill, and the movable unit The 60 series is moved up in a sliding manner until the upper end of the movable unit 60 abuts against the window sill. In many embodiments, the device 10 includes a one-way brake 150 that allows the movable unit 60 to self-hold in this type of configuration, making it easier for the user to install. One type of one-way brake can include a first engaged configuration in which the brake allows the movable unit 60 to move Leaving the first unexpanded configuration moves toward the second expanded configuration. However, in the first engaged configuration, the brake prevents the movable unit from moving away from the second deployed configuration toward the first unexpanded configuration. Referring to Figure 14, this type of one-way brake allows the movable unit 60 to move upwards as desired; and, the unit 60 can then be left at any desired position without being forced by gravity to slide back down. mobile. In a particular embodiment, one of the engaged configuration brakes 150 has a preset configuration, meaning that the brake is always in the engaged configuration unless a user acts to brake the brake from the engaged set. The state is removed and actively prevents the brake from returning to the engaged configuration. This allows the user to slide the unit 60 up in a sliding manner without having to perform any action (e.g., pressing a button, turning a lever, etc.) to release the brake. The user also does not have to perform any such action continuously or intermittently during the process of moving the unit 60 up in a sliding manner.

In at least some embodiments, the brake 150 can be actuated (eg, manually by a user) into a second disengagement configuration that allows the movable unit 60 to configure the first unexpanded configuration and the second unfolded configuration Move back and forth reversibly (for example, up and down) in either direction. Thus, when desired to place the device 10 in an undeployed state (e.g., such that the device 10 can be more easily removed from the window), the brake 150 can be actuated into the second disengaged configuration. In embodiments where the engaged configuration of the brake 150 is a predetermined configuration, actuation must be maintained to keep the brake disengaged to cause the unit 60 to continue moving toward the first unexpanded configuration. That is, if the actuation is performed, such as by pressing a button, the user must continue to press the button to continue moving the unit 60 toward an undeployed configuration.

The brake 150 can take the form of any braking device or braking mechanism that can perform the one-way braking described above when engaged and can permit two-way motion when disengaged. In various In an embodiment, such a one-way braking device may rely on such as a ratchet, a gear, or the like. However, in some embodiments, the brake 150 is a non-stepped brake, meaning that the brake 150 is configured such that when the brake is in the engaged configuration, the brake allows the movable unit 60 to be in a continuous manner ( For example, moving away from the second unexpanded configuration toward the second deployed configuration, in any desired amount, such as a fraction of one millimeter, rather than a stepwise increment. (This type of brake will also allow continuous, rather than stepwise, movement in either direction when disengaged.)

Any suitable one-way, non-stepping brake can be used as desired. In some embodiments, such a type of brake can rely on one or more cams, each of which includes a projection that, when in a first engaged configuration, frictionally strikes a rod at an angle so that Allow movement in one direction rather than in the opposite direction. The one or more cams are rotatable to a second disengagement configuration in which the cam's projections are spaced from the rod to permit movement in either direction. This general-purpose one-way non-stepping brake is disclosed in U.S. Provisional Patent Application No. xx/xxxxxx (Attorney Docket No. 76671 US002), entitled "Unpowered Window Air Filter Apparatus", filed on the same day as the present application. The full text is incorporated herein by reference. In other embodiments, such a type of one-way non-stepping brake can rely on a brake member that, when in a first engaged configuration, frictionally strikes a slider rod to allow for one direction rather than relative Direction of movement. The brake member can be actuated to a second disengagement configuration in which it allows movement in either direction. This general-purpose one-way non-stepping brake is the US Provisional Patent Application No. xx/xxxxxx (Agent No. xxxxxx) of the invention entitled "Powered Window Air Filter Apparatus" filed on the same day as the present application. The entire text of the specification is incorporated herein by reference. Any brake of this type can be actuated by any suitable actuator, such as a button, a handle to be rotated or pulled, and the like.

As discussed above, in at least some embodiments, the movable unit 60 of the device 10 can be moved (eg, up) toward an unfolded configuration, and a one-way brake 150 can cause the movable unit 60 to not go back down Move to any appreciable extent (even if the user releases the movable unit 60) unless the brake is disengaged. When the brake is disengaged, the movable unit 60 can then move downward (or allow downward movement under the influence of gravity). In some embodiments, it may be advantageous for device 10 to include a one-way speed limiter 160 that limits movement of movable unit 60 toward the first unexpanded configuration away from the second deployed configuration. Speed (such movement will correspond to a downward direction relative to the surface in most uses of device 10). However, the limiter 160 will not significantly limit the speed at which the movable unit 60 can move away from the first unexpanded configuration toward the second deployed configuration (this type of movement will correspond to an upward direction in most uses of the device 10) ). Limiter 160 can have any suitable design and be operated by any suitable motion mechanism. An exemplary type of limiter 160 is described in detail in U.S. Provisional Patent Application Serial No. xx/xxxxxx (Attorney Docket No. 76687 US002), which is hereby incorporated by reference. The entire text is incorporated herein by reference.

Regardless of the particular configuration and components, such a speed limiter can ensure that when a one-way brake is actuated to disengage the brake to allow the movable unit 60 to move downward toward an un-deployed configuration, the limiter ensures Earth gravity does not cause unit 60 to Move too fast at a slow speed. It will thus be appreciated that the configuration disclosed herein may allow a user to grasp the base unit 20 (eg, by grasping either of the lower handle 22 or the upper handle 23) and press the actuator button 34. This may allow the movable unit 60 to descend slowly, driven by gravity but limited by the limiter 160, and the user does not have to grasp any portion of the movable unit 60 during this procedure. (To lift the unit 60 to an unfolded state, the user can of course grasp the handle 22 or 23 of the base unit 20 with one hand and grasp the handle 62 of the movable unit 60 with the other hand to raise the unit 60 because it is here The direction shifting unit 60 does not have to press the actuator button 34.)

If desired, device 10 can include a fragrance element that can be inserted at any convenient point along the air path from inlet 71 to outlet 31. The moving air can strike the fragrance element (e.g., if the fragrance element is a web such as a perfume loaded, air can pass through the fragrance element) to cause any evaporation therein. (The term "scent" is used broadly to encompass a user such as any fragrance, essential oil, etc., which may be intended to be dispersed into, for example, a living space.) In some embodiments, a fragrance element may be As mentioned in one of the webs, the web can be inserted into the air path, such as through an entry slot. Or a fragrance element can be provided by having a container or path into which a liquid fragrance (e.g., essential oil) can be placed (such as using a dropper) and the liquid fragrance can follow a first-class path from here. The air path.

If desired, one piece (e.g., an elongate length) of elastic material (e.g., foam rubber, weather stripping, or the like) can be inserted into the glass of the movable frame 301 and other (for example, not immovable Between the glass of the frame 304 (e.g., at location 318 of Figure 14) to minimize any passage of unfiltered air through the small gap between the glass layers (attributable to the window being ( Part) Open). Also, if desired, a window stop can be positioned at a location 319 such as FIG. This type of window stop ensures that the movable frame 301 does not inadvertently move (to the left, in the view of Figure 14) away from its lateral side of one of the devices 10. Such a window stop can be any suitable item (eg, a rubber wedge whose leading edge can grip the trailing edge of the movable frame 301; an elongated rod with one end abutting the trailing edge of the movable frame 301, The other end is next to the side column of the window frame, etc.). Any one or both of such one or more pieces, such as weather strips and a window stop, may be included in a kit, such as comprising a device 10 (which may already have a filter installed therein) Assembly 250), and the kit includes one or more replacement filter assemblies, instructions for use, and the like.

While the discussion herein has focused on a frame window having a frame that can be moved horizontally and has a frame that is fixed to position, it will be appreciated that the device 10 can be easily installed in a window containing two horizontally movable frames. (In such cases, it is optional to move any of the frames to provide a window opening for mounting the device 10 therein). Moreover, although the discussion herein has focused on a horizontal frame window (meaning a window having at least one movable frame that is movable at least substantially in one of the horizontal directions relative to the surface), It is understood that the device 10 can be easily mounted in a vertical frame window (meaning a window having at least one movable frame that is movable in at least substantially one of the directions perpendicular to the ground). In this type of situation, the movable frame can be moved upward to provide an opening having a vertical span sufficient to accommodate the lateral direction (width) of the device 10. The device 10 can then be positioned such that the device The "lower" end 28 of 10 abuts against the first side post of the window and causes the "upper" end 68 of the device 10 to abut against the second side post of the window, and wherein a lateral direction of the device 10 The side leans against the window sill of the window. Thereafter, the vertically movable frame can then be moved downwardly such that its leading edge abuts the other lateral side of the device 10. (The device 10 can also be mounted in one of the openings in the upper part of a vertical frame window, rather than in one of the openings in the lower part.)

It will thus be appreciated that the installation and use of device 10 in a vertical frame window can be performed in the same manner as described herein for a horizontal frame window, wherein device 10 is only rotated relative to the surface, such as 90 degrees. Thus, the terms used herein, such as upper, lower, above, below, uppermost, lowermost, etc., will be understood for convenience. An exemplary embodiment of installing device 10 in a horizontal frame window; it should be emphasized that such wording does not limit the use of device 10 to a horizontal frame window.

Ability to convert to indoor air purifier

In at least some embodiments, the electric air filter device 10 can be converted from a window air filter device to a motorized indoor air cleaner (RAP). When used as a RAP, the device 10 will break into the room air, filter the air, and recirculate it into the chamber instead of breaking into the outdoor filtered air and releasing it into the chamber. In the simplest embodiment, the device 10 can be simply suspended from a wall (or even against a wall, for example with the upper end 68 of the device 10 against a wall and the lower end 28 of the device 10 resting against, for example, the floor. the way). Just need to ensure that the air inlet 71 is unobstructed (for example by a wall surface or Blocked by any other indoor object) so that device 10 cannot receive enough air to function as needed. This can be done, for example, by hanging the device 10 on a wall (or ceiling) or by having the device 10 lean against a wall and leaving sufficient space between the weather shield 72 and such as a wall (eg, one centimeter or more). ) is achieved by allowing airflow into the air inlet 71. Such considerations may be particularly important, for example, if the weather shield 72 is in the form of a set of louvers. However, using a weather shield such as that exemplified in FIG. 2 (where the airflow enters from the side and/or bottom of the weather shield, such as directly into the thickness of the device 10), the weather shield 72 The gap between the side and the body of the panel portion 75 of the movable unit 60 of the device 10 may be sufficient to allow sufficient airflow even if the device 10 is positioned, for example, such that the weather shield 72 lies snugly against a wall (or any other The same applies to the surface). For example, in some embodiments, the device 10 can even be placed flat on a floor or on a shelf with the air inlet 71 and weather shield 72 facing down, with the air outlet 31 facing upward.

Therefore, in such embodiments, it is almost unnecessary to make special provisions for the device 10 to function as an indoor air cleaner. However, in some embodiments, device 10 may be provided with one or more brackets, spreaders, or the like (eg, spreader 511 as shown in the illustrative embodiment of FIG. 11), whereby The device 10 is mounted to a wall or to any other suitable surface or suspended such as on a ceiling or raft. In some embodiments, the spreader 511 can be mounted in a position on the movable unit 60 of the device 10 that is an interior side 61 of the proximity unit 60 such that the spreader 511 does not interfere with the earlier described herein. The ability to position the upper end 68 of the device 10 against a window sill. Furthermore, the spreader 511 can be hingedly connected to the unit 60, for example, such that the spreader 511 can be moved in a rotational direction in a direction that moves the distal end of the spreader away from the unit The upper end 68 of 60. This may allow the spreader 511 to move inwardly and/or downwardly relative to the upper end 68 of the unit 60, such as when the spreader 511 is not required.

If desired, the brake 150 can be configured (or a separate locking mechanism can be provided) to prevent the base unit 20 from sliding relative to the unit 60 when the device 10 is suspended in such a manner as a spreader. Move down. In other words, such provisions may allow device 10 to be in its first unexpanded configuration while suspended (if needed).

In some embodiments, device 10 can be used with a support base 500, as shown in the illustrative embodiments of FIGS. 12 and 13. In some embodiments, the base 500 can only be used to support and stabilize the device 10, such as in an upright position. The base 500 can thus include a body 501 having a sufficient length and width to cover a sufficient surface area (e.g., a floor) to provide stability and having an open-ended upwardly facing recess 502 (e.g., a slot), The recess is configured to receive the lower end 28 of the device 10. Such a recess can be designed to accommodate the lower handle 22 of the device 10 (if such a lower handle is present and protrudes far enough down); or the handle 22 can be resized, for example, and/or slightly adjusted upwards (relocate) So as not to prevent the device 10 from being placed into the recess 502 of the base 500.

In various embodiments, the base 500 can include a body 501 having a bottom surface 503 having an area (eg, a floor contact area) of at least about 1000, 2000, 4000, or 8000 square centimeters. In some embodiments, body 501 can be a shape such as a rectangle, an ellipse, or other otherwise elongated shape, with a long axis configured to align with the lateral axis of device 10. In some embodiments, at least a portion of the body 501 can be covered by a decorative cover, panel, or skirt. The main body 501 can mold plastic and gold Genus, or in some combination or assembly. If desired, the bottom surface 503 of the body 501 can include a non-slip surface (e.g., rubberized material or the like). Specifically, if the body 501 is made of plastic, it may be weighted, for example, with metal, sand, water, or the like to enhance stability. It will be appreciated that one of the devices 10 of the general type previously presented herein is designed in which the fan 117 and, in particular, the motor 118 (which will one of the heaviest individual components of the device 10) are relatively low in the device 10 ( For example, in the abutment portion 36 of the base 20)) a device 10 having a relatively low center of gravity can be provided. When the device 10 is installed in the base 500, this can further be used to enhance the stability of the device 10 from dumping.

As mentioned, a recess 502 can be provided that is sized and shaped to snugly incorporate the lower end 28 of the device 10. If desired, at least a portion of the surface defining the body 501 of the recess 502 can be lined with a layer of elastomeric material to provide a cushioning function. In some embodiments, one or more latches, fasteners, or the like can be provided to secure the lower end 28 of the device 10 to the base 500. Such fasteners may be of a type that automatically locks into position when the lower end 28 of the device 10 is inserted into the base 500; or such fasteners may be manually secured by a user. Locking the device 10 to the base 500 in this manner (either automatically or manually) may advantageously be such that by simply grasping the handle 22, 23, or 62, such as the device 10, when the device 10 needs to be moved to a different position. One or more of them pick up both the device 10 and the base 500 at the same time. If desired, in some embodiments, base 500 can include any number (eg, two, three, or four) of wheels that protrude downward therefrom to cause base 500 (device 10 is on or off) Positioning) can travel round to a desired position across a floor. If necessary, the base 500 can There is a channel (e.g., a pipe or channel) 506 through which a power cord can pass (if needed).

The above discussion has been limited to embodiments in which the base 500 provides only a mechanical support and stabilizing function. In a further embodiment, the base 500 can also perform one or more electrical functions. For example, in some embodiments, the base 500 can be used to recharge an internal power source (eg, a rechargeable battery) of the device 10. In such an embodiment, the base 500 can include a power cord 504 that is inserted into a conventional electrical outlet. The base 500 (eg, its recess 502) can then include a set of electrical contacts 505 that are configured to contact a set of complementary electrical contacts of the device 10 (such contacts can be positioned on a base such as the device 10 The lower end 28 of the unit 20 or near the lower end 28). Base 500 may also include, for example, one or more auxiliary electrical components (eg, a transformer, a surge protector, etc.), if desired. Whether the rechargeable battery of device 10 is charged through a connector provided in base 500 or directly via an external power cord connected to device 10, device 10 can be recharged while being supported by base 500 (also The device 10 can be operated to purify indoor air during the recharging of the device 10.
