Definitions

The following definitions apply herein, unless otherwise indicated.
“Comprising,” “including,” and “having” (and conjugations thereof) are used interchangeably to mean including but not necessarily limited to, and are open-ended terms not intended to exclude additional, unrecited elements or method steps.
Terms such as “first”, “second”, and “third” are used to distinguish or identify various members of a group, or the like, and are not intended to show serial or numerical limitation.
“AKA” means “also known as,” and may be used to indicate an alternative or corresponding term for a given element or elements.
“Elongate” or “elongated” refers to an object or aperture that has a length greater than its own width, although the width need not be uniform. For example, an elongate slot may be elliptical or stadium-shaped, and an elongate candlestick may have a height greater than its tapering diameter. As a negative example, a circular aperture would not be considered an elongate aperture.
“Coupled” means connected, either permanently or releasably, whether directly or indirectly through intervening components.
“Resilient” describes a material or structure configured to respond to normal operating loads (e.g., when compressed) by deforming elastically and returning to an original shape or position when unloaded.
“Rigid” describes a material or structure configured to be stiff, non-deformable, or substantially lacking in flexibility under normal operating conditions.
“Elastic” describes a material or structure configured to spontaneously resume its former shape after being stretched or expanded.
“Processing logic” describes any suitable device(s) or hardware configured to process data by performing one or more logical and/or arithmetic operations (e.g., executing coded instructions). For example, processing logic may include one or more processors (e.g., central processing units (CPUs) and/or graphics processing units (GPUs)), microprocessors, clusters of processing cores, FPGAs (field-programmable gate arrays), artificial intelligence (AI) accelerators, digital signal processors (DSPs), and/or any other suitable combination of logic hardware.
A “controller” or “electronic controller” includes processing logic programmed with instructions to carry out a controlling function with respect to a control element. For example, an electronic controller may be configured to receive an input signal, compare the input signal to a selected control value or setpoint value, and determine an output signal to a control element (e.g., a motor or actuator) to provide corrective action based on the comparison. In another example, an electronic controller may be configured to interface between a host device (e.g., a desktop computer, a mainframe, etc.) and a peripheral device (e.g., a memory device, an input/output device, etc.) to control and/or monitor input and output signals to and from the peripheral device.
Directional terms such as “up,” “down,” “vertical,” “horizontal,” and the like should be understood in the context of the particular object in question. For example, an object may be oriented around defined X, Y, and Z axes. In those examples, the X-Y plane will define horizontal, with up being defined as the positive Z direction and down being defined as the negative Z direction.
“Providing,” in the context of a method, may include receiving, obtaining, purchasing, manufacturing, generating, processing, preprocessing, and/or the like, such that the object or material provided is in a state and configuration for other steps to be carried out.

Overview

In general, a ventilation system of the present disclosure includes a recessed housing integrated into a wall or ceiling. The housing of the ventilation system is configured to sit inside the structural framing of the wall, such that a peripheral lip of the housing is disposed substantially coplanar with an outermost layer of the wall (i.e., the drywall, tiling, façade, etc.). A front panel is configured to sit within the housing such that the front panel is also coplanar with the outmost layer of the wall.
The housing and front panel are configured such that the outer lip of the housing circumscribes the periphery of the front panel and leaves a gap therebetween. In some examples, the front panel and housing is substantially rectangular, and the gap is disposed on all four sides of the panel. In some examples, the gap may be disposed only on the top, the bottom, either side, or, alternatively, any combination thereof. In some examples, the panel may be triangular, oval, trapezoidal, or otherwise shaped.
Ventilation systems of the present disclosure include a fan (AKA blower) configured to draw air from the kitchen into the housing of the ventilation system through the gap described above. In general, the ventilation system may be either recirculating or externally exhausting. A recirculating ventilation system draws air in from the kitchen through a first portion of the gap and redirects it back out into the kitchen through a second portion of the gap. An externally exhausting ventilation system draws air in from the kitchen and directs it through a duct to an external vent disposed outside the kitchen, e.g., outside of the building.
Ventilation systems of the present disclosure include a filter system disposed within the housing. The filter system may comprise a single filter or a plurality of filters and/or filter layers disposed in the airflow path. The filter system may be accessible by the user e.g., by displacement or removal of the front panel. Air is drawn through the filter by the blower, thereby removing particulates/contaminates from the air. The air is then either directed back into the kitchen (e.g., in a recirculating system), or out of the kitchen/building (e.g., in an externally venting system).
In some examples, ventilation systems include electronics (e.g., a controller) configured to monitor the filter and airflow of the ventilation system as well as provide a user interface for controlling aspects of the ventilation (e.g., turning the ventilation system on and off, changing the power of the fan, etc.). In some examples, the user interface may be disposed on the front panel. In some examples, the electronics may include a timer configured to be reset by the user when a new filter is placed in the ventilation system, to track and indicate the age of the current filter. In some examples, an air flow sensor is configured to measure the air flow of the ventilation system in real-time. Data from the electronic monitoring system may be retrieved through the user interface or transmitted to an application (e.g., on a personal computer or smartphone associated with the user).
In some examples, the ventilation system includes a distributed ventilation system having a plurality of ventilation system modules—such as a master module and one or more assistant modules. Each module may include all the features of the above-described ventilation systems. In some examples, the master module includes the user interface in the front panel and is configured to communicate with the one or more assistant modules, for example using a wired connection, a wireless connection (e.g., Bluetooth, Wi-Fi, etc.), or another suitable communication means.
In some examples, the ventilation modules of the distributed ventilation system are recirculating, externally exhausting, or any combination thereof. In examples where multiple modules of the distributed ventilation system are externally exhausting, each of the modules may have a respective exhaust and duct configured to join together at a main duct, which may be coupled to an external vent disposed outside of the building.

EXAMPLES, COMPONENTS, AND ALTERNATIVES

The following sections describe selected aspects of ventilation systems of the present disclosure, as well as related systems and/or methods. The examples in these sections are intended for illustration and should not be interpreted as limiting the scope of the present disclosure. Each section may include one or more distinct embodiments or examples, and/or contextual or related information, function, and/or structure.

A. Illustrative Ventilation System

As shown in FIGS. 1-17, this section describes examples of the ventilation systems described above, configured to be hidden within a wall of a kitchen behind the cooktop and integrated into the backsplash of the kitchen wall.
In some examples, the ventilation systems described below are recirculating ventilation systems (i.e., air is drawn into the system and returned to the kitchen). In other examples, the ventilation systems described below are externally exhausting ventilation systems (i.e., air is drawn into the system and ducted to an environment exterior to the room, home, or building). A more detailed description of these two examples is provided below.
Each of the example ventilation systems described below are similarly numbered, for example, a ventilation system 100 includes a housing 102 and, likewise, a ventilation system 200 includes a housing 202. For any given ventilation system described below, components share similar features with similarly numbered components unless stated otherwise.
As shown in FIG. 1, a housing 102 of ventilation system 100 is configured to be disposed within a wall (e.g., a backsplash) adjacent a cooktop 104 (e.g., a cooking range) such that a peripheral lip 106 of the housing 102 is disposed substantially coplanar with an outermost layer of the wall (i.e., the drywall, tiling, façade, etc.). A front panel 108 having a peripheral panel lip 107 is disposed within housing 102, such that panel lip 107 of front panel 108 is coplanar with lip 106 and the outmost layer of the wall.
Housing 102 and front panel 108 are configured such that lip 106 of the housing circumscribes the front panel, leaving a gap 110 therebetween. In the current example, front panel 108 and housing 102 are substantially rectangular. Portions of gap 110 may be utilized by ventilation system 100 for air intake. Similarly, portions of gap 110 may be utilized by ventilation system 100 for air exhaust. Gap 110 may have any suitable dimensions configured to facilitate adequate airflow. For example, gap 110 may be between 0.25 inches and 6 inches. In some examples, gap 110 does not exceed 25% of a width of panel 108 on any given side.
The removable front panel is designed such that standard or custom wall covering, e.g., custom backsplash material (tile, granite, metal, glass, etc.), may be mounted to the panel to match the surrounding wall or backsplash, or to create a specific design contrast. This backsplash material may be mounted by fastening from the rear, or by using an adhesive such as those designed specifically for mounting tile, or other adhesives specific to the application.
As shown in FIG. 1, gap 110 may be disposed on all four sides of panel 108. In this example, panel 108 may be proportionally similar to lip 106, such that gap 110 maintains a same or similar width on all four sides of panel 108. This configuration enables proportional airflow on all sides of panel 108, either during intake or exhaust. This configuration may be advantageous in an externally exhausting ventilation system, where gap 110 functions entirely for air intake.
As shown in FIG. 2, a panel 208 may be configured such that a gap 210 comprises a bottom gap 210A at the bottom portion of panel 208 and a top gap 2108 at the top portion of panel 208. In this example, the distance between the two sides of panel 208 and a lip 206 is reduced or eliminated, such that minimal airflow is allowed through the sides.
FIGS. 3 and 4 depict further examples of front panels and gaps. Namely, in the example shown in FIG. 3, a front panel 308 may be configured such that a gap 310 is present at the sides and the top, but the bottom gap is closed. FIG. 4 depicts an example wherein a gap 410 is only meaningfully present at the top of a front panel 408.
Turning to the sectional side views of FIGS. 5 and 6, all of the front panels described herein include a panel housing 512 and a decorative face 514. Panel housing 512 comprises a peripheral panel lip 507 and a planar expanse 509. Decorative face 514 may include any suitable wall covering or other material configured to match a covering, pattern, and/or decoration of the surrounding wall. Adhesive may be disposed between decorative face 514 and planar expanse 509 to affix the face to housing 512. In some examples, grout is disposed between the periphery of face 514 and panel lip 507 (and/or elsewhere) to match a pattern of the wall.
As depicted in FIG. 6, all of the front panels described herein may alternatively include a decorative face 614, which may include a plurality of sub-pieces (e.g., tiles) affixed to a planar expanse 609 of a panel housing 612, for example, with adhesive. Each sub-piece of the decorative face may be separated by grout. This arrangement may be particularly advantageous when any one of the front panels described herein is installed in a kitchen having a tiled backsplash. Decorative face 614 may be configured to match a tiling of the tiled backsplash such that the panel and backsplash are substantially similar in appearance. In some examples, portions of decorative face 614 may extend past a peripheral panel lip 607 of panel housing 612 to mate with tiles of the tiled backsplash such that portions of the front panel are nearly indistinguishable from portions of the backsplash. For example, one or more edges of face 114 may be castellated and/or otherwise configured to interdigitate or interlock with edges of the surrounding wall.
Turning to FIGS. 7-10, the ventilation systems described herein may be configured to exhaust air externally. In these embodiments, the ventilation systems further comprise a blower, a filter system, and ductwork. The blower is configured to draw air into the housing through a gap (e.g., gap 110, 210, 310, etc.), and further draw the air through the filter system. The filter system may comprise a single filter or a plurality of filters of similar or differing material. The filter system may include paper products, polypropylene, activated carbon, polyurethane, polyester, metal, and/or another suitable air filtering material. Additionally, or alternatively, the filter system may include electrostatic filtration. The air is then directed through the ductwork to an external exhaust vent (not shown).
In the example depicted in FIG. 7, blower 716 is disposed within housing 702, and filter system 718 is similarly disposed therein. Filter system 718 is shown vertically aligned and parallel with front panel 708, disposed entirely across housing 702, and positioned in between the front panel and blower 716. In this example, gap 710 is disposed at least at the top and bottom of front panel 708 and blower 716 is configured to draw in air from all portions of gap 710. The air is then directed through filter system 718, thereby removing particulates from the air before being pulled into blower 716.
After filtering, the air is directed into ductwork 720. Ductwork 720 may be disposed within the wall, concealed from the view of a user. The filtered air is moved by the blower through the ductwork to the external vent. In some examples, ductwork 120 may be insulated, e.g., with a fire-retardant material.
FIG. 8 depicts ventilation system 800 in an externally exhausting configuration. Front panel 808 and filter system 818 are arranged similar to ventilation system 700, described above. Blower 816 is shown disposed within ductwork 820 instead of within housing 802. This configuration enables housing 802 to be smaller than in the example of ventilation system 700, e.g., if ventilation system 800 is to be installed in a narrow or thin wall.
In this example, blower 818 draws air in through gap 810, then filter system 818, and finally through portions of ductwork 820 before passing through the blower. This arrangement enables hot air to cool as it passes through the ductwork before contacting the blower, thereby protecting the blower from high temperatures. The blower then directs the air to the external vent.
In the examples depicted in FIGS. 9 and 10, front panels 908 and 1008 are configured such that gaps 910 and 1010 are only present between the tops of front panels 908 and 1008 and housings 902 and 1002, respectively, therefore air is restricted to enter housings 902 and 1002 from the top. Accordingly, filter system 918 may be disposed orthogonal to front panel 908 (e.g., in FIG. 9), and filter system 1018 may be disposed diagonal to front panel 1008 (e.g., in FIG. 10). This arrangement enables filter systems 918 and 1018 to be smaller than the previous examples described above, therefore requiring less material and cost. Blower 918 may be disposed within ductwork 920.
Turning to FIGS. 11-14, the ventilation systems described herein may be configured to recirculate the air back into the kitchen after filtering. In some examples, the air may be exhausted from the housing through the same portion of the gap from which the air is drawn. In other examples, the air may be redirected through a different portion of the gap, or directed through ductwork to another portion of the kitchen.
In the example shown in FIG. 11, front panel 1108 of ventilation system 1100 may be configured such that gap 1110 is present at least at the top and the bottom. Blower 1116 is disposed within housing 1102 with filter system 1118 disposed directly at an air intake of the blower. Blower 1116 may draw air in from any portion of gap 1110 and through filter system 1118. In this example, there is additionally a baffle plate 1122 disposed proximate an exhaust of blower 1116. Baffle plate 1122 is configured to direct the air from the exhaust of blower 1116 toward a portion of gap 1110 (e.g., at the top of the front panel). The air exhausting from gap 1110 may provide an air-curtain effect as air discharging from the top of ventilation system 1100 creates a barrier for ambient air in the kitchen, particularly ambient air directly above the cooktop. The air-curtain effect may prevent air contaminated from cooking from escaping upward, past the exhausting air. Additionally, this arrangement may encourage the intake of air into ventilation system 1100 by restricting the air to the region proximate gap 1110.
In the example shown in FIG. 12, air is drawn into housing 1202 of ventilation system 1200 through gap 1210A positioned at the bottom of front panel 1208 by blower 1216. Filter system 1218 may be disposed generally orthogonal to front panel 1208 below the blower. Air is drawn through filter system 1218 and directed upward, toward gap 1210B.
FIG. 13 depicts ventilation system 1300 having a recirculating configuration. In this example, gap 1310 may be present at least at the top and the bottom of front panel 1308. Blower 1316 is configured to draw air in from all portions of gap 1310 and direct the air generally downward through filter system 1318. In this example, blower 1316 is disposed within ductwork 1320, below housing 1302. Similar to ventilation system 1100, baffle plate 1322 is disposed proximate the exhaust of blower 1316 and configured to direct the air out of the top portion of gap 1310. This configuration may additionally create an air-curtain as described above.
Ventilation system 1400 having a recirculation configuration is depicted in FIG. 14. In this example, gap 1410 is only present at the top of front panel 1408 and blower 1416 is disposed within housing 1402. The top portion of gap 1410 and the bottom portion of gap 1410 are separated from each other (i.e., partitioned) by an angled baffle plate 1422. Intake air is drawn in through the bottom portion of gap 1410 by blower 1416. The intake air then passes through filter system 1418. After filtering, the air is directed by baffle plate 1422 and exhausted through the top portion of gap 1410. In other words, the intake and the exhaust of ventilation system 1400 both occur through the same gap or opening between the panel and the wall. Exhausted air passing through the top portion of the gap entrains ambient air above gap 1410 to create an air-curtain, such that contaminated intake air is prevented from escaping upwards past gap 1410, and instead encouraged into the bottom portion of gap 1410.
As shown by the examples of FIGS. 7-10 and FIGS. 11-14, many advantageous configurations of a ventilation system may be utilized in the present disclosure, some providing different advantages than others.
Turning now to FIGS. 15-17, all of the front panels described herein are configured to be positionable or removable, such that the filter system may be accessed by the user, e.g., to replace a filter. The front panels may be configured to pivot up, pivot down, or pivot to the side using a hinge. A latching system is utilized in some examples to secure the panel in place while closed.
In some examples, the front panel may be attached to a telescoping system to allow removal or, alternatively, the front panel may be attached to the ventilation system via a press-to-latch/press-to-release fastening system. Other methods of attaching and latching the front panel may be utilized.
In the example depicted in FIG. 15, front panel 1508 is configured to pivot upwards about a rotational axis defined by hinge 1524. Latching system 1526 is utilized to secure front panel 1508 while the front panel is closed. Latching system 1526 may be magnetic and/or mechanical. To access the interior of housing 1502 and filter system 1518 therein, the user disengages latching system 1526 and pivots front panel 1508 upwards. To close the panel, the user manually rotates the panel downwards until latching system 1526 engages and the panel is shut and flush with the wall.
FIGS. 16 and 17 depict examples wherein the front panel is removable. As shown in FIG. 16, front panel 1608 may be configured to pull directly out from housing 1602.
For example, front panel 1608 may be friction fitted with housing 1602, such that the user may simply pull the front panel out to access filter system 1618 and similarly push the panel back into place, until the panel is fully inserted and flush with the wall. This example may be configured to utilize a latching system (e.g., latching system 1526) for additional securement.
In the example depicted in FIG. 17, front panel 1708 is configured to pivot forward a specified amount before a user can remove the front panel from housing 1702. This example utilizes latching system 1726 and a peg hinge 1728. Peg hinge 1728 comprises a peg 1730 configured to sit within a recess 1732 in housing 1702. Peg hinge 1728 may be configured such that, in response to the user rotating front panel 1708 outward, peg 1730 tilts and moves rearward within recess 1732, thereby displacing front panel 1708 in a downward direction. This displacement, in concert with the outward rotation of the front panel, disengages latching mechanism 1726 and enables peg 1730 to be removed from recess 1732. Accordingly, front panel 1708 may then be removed from housing 1702 and filter system 1718 may be accessed. To close front panel 1708, the user places peg 1730 into recess 1732 and rotates the front panel until latching mechanism 1726 engages and the front panel is flush with the wall.

B. Illustrative Distributed Ventilation System

As shown in FIGS. 18-23, this section describes a distributed ventilation system 2000 (see FIG. 20), comprising ventilation system modules configured to be hidden within a wall and integrated into a decorative design of the wall. In general, distributed ventilation system 2000 includes a master module 1800 and a plurality of assistant modules 1900 (see FIGS. 18 and 19, respectively). Various examples of ventilation system modules are described below, though any of the ventilation systems described above (e.g., ventilation system 100, 200, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, etc.) may be utilized as a module in distributed ventilation system 2000. In other words, the ventilation systems described above may be utilized as either the master module or assistant modules in distributed ventilation system 2000, in any combination. For example, distributed ventilation system 2000 may include one or more modules comprising ventilation system 100 in combination with one or more modules comprising ventilation system 200, etc.
In some examples, the one or more of the modules utilized in the distributed ventilation system are recirculating ventilation systems (i.e., air is drawn into the system and returned to the same room (e.g., a kitchen), see FIG. 22). In other examples, one or more of the modules are externally exhausting ventilation systems (i.e., air is drawn into the system and ducted to an environment exterior to the room, home, or building, see FIG. 23).
As shown in FIG. 18, master module 1800 includes a housing 1802 configured to be disposed within a wall, for example, adjacent a cooktop. As with the ventilation systems described above, a peripheral lip 1806 of the housing 1802 is disposed substantially coplanar with an outermost layer of the wall (i.e., the drywall, tiling, façade, etc.). A front panel 1808 having a peripheral panel lip 1807 is disposed within housing 1802, such that panel lip 1807 of front panel 1808 is coplanar with lip 1806 and the outmost layer of the wall.
Housing 1802 and front panel 1808 are configured such that lip 1806 of the housing circumscribes the front panel, leaving a gap 1810 therebetween. In the current example, front panel 1808 and housing 1802 are substantially rectangular. In some examples, portions of gap 1810 may be utilized by master module 1800 for air intake. In some examples, such as when master module 1800 is a recirculating ventilation system, portions of gap 1810 may be utilized by master module 1800 for air exhaust. Gap 1810 may have any suitable dimensions configured to facilitate adequate airflow.
As with the ventilation systems described above, front panel 1802 is designed such that standard or custom wall covering, e.g., custom backsplash material (tile, granite, metal, glass, etc.), may be mounted to the panel to match the surrounding wall or backsplash, or to create a specific design contrast. This backsplash material may be mounted by fastening from the rear, or by using an adhesive such as those designed specifically for mounting tile, or other adhesives specific to the application. For a more detailed description of front panel configurations, including decorative facing, see the discussion above with respect to FIGS. 5 and 6.
Master module 1800 includes a user interface 1812 (UI) on front panel 1808. User interface 1812 may comprise one or more buttons and/or touch controls for controlling electronic aspects of distributed ventilation system 2000 (including master module 1800 and assistant module(s) 1900), such as power, fan speed, etc. In some examples, user interface 1812 utilizes electronics (e.g., processing logic and/or sensors disposed at least partially within the housing) to monitor and/or control aspects of a filter system. For example, user interface 1812 may include a timer for indicating when a filter of the filter system should be replaced. In some examples, UI 1812 comprises or is part of an electronic controller. In some examples, user interface 1812 may be coupled to an air flow sensor configured to measure the air flow of the ventilation system, such that data from the air flow sensor is displayed on user interface 1812.
Turning to FIG. 19, assistant module 1900 is depicted. Similar to the description above with respect to master module 1800, assistant module 1900 includes a housing 1902 configured to be disposed within a wall. A peripheral lip 1906 of housing 1902 is disposed substantially coplanar with an outermost layer of the wall. A front panel 1908 having a peripheral panel lip 1907 is disposed within housing 1902, such that panel lip 1907 is coplanar with lip 1906 and the outmost layer of the wall. Unlike master module 1800, assistant module 1900 does not include a user interface in the front panel.
Housing 1902 and front panel 1908 are configured such that lip 1906 of the housing circumscribes the front panel, leaving a gap 1910 therebetween. As with other ventilation systems described herein, portions of gap 1910 may be utilized by assistant module 1900 for air intake. In some examples, such as when assistant module 1900 is a recirculating ventilation system, portions of gap 1910 are utilized for air exhaust. Gap 1910 may have any suitable dimensions configured to facilitate adequate airflow.
As with the ventilation systems described above, front panel 1902 is designed such that standard or custom wall covering, e.g., custom backsplash material (tile, granite, metal, glass, etc.), may be mounted to the panel to match the surrounding wall or backsplash, or to create a specific design contrast. This backsplash material may be mounted by fastening from the rear, or by using an adhesive such as those designed specifically for mounting tile, or other adhesives specific to the application.
In some examples, master module 1800 and/or assistant module 1900 are dimensioned to be fitted between studs of a building, for example having a height and/or width matching a standard stud spacing, to be easily installed during construction. In some examples, the height and/or width of the modules is configured to fit between wall studs the centers of which are spaced at 16-inch intervals. For example, a module may be configured to fit into a 14.5-inch gap between the studs. In some examples, master module 1800 and/or assistant module 1900 includes one or more biasing mechanisms (e.g., springs, resilient fingers, etc.), disposed on the outside of the housing, such that, when the module is installed between studs, the biasing mechanism holds the module in place, with or without additional fastening means. These biasing mechanisms can also accommodate slight variation in the spacing between studs.
Turning to FIGS. 20 and 21, distributed ventilation system 2000 is shown in two configurations, labeled A and B, respectively. For purpose of illustration, the two configurations depict master module 1800 in a specific position in the distributed system. This is to show that there is generally one master module and a plurality of assistant modules. In some examples, the master module and assistant modules may be disposed in a configuration substantially similar to one of those shown in FIGS. 20, 21, though the exact layout and distribution of the system may be changed depending on the application. It is appreciated that master module 1800 may be in any position in the distributed system, including at a separate physical location from any of the assistant modules. For example, the master module may be located at an easily accessible location (e.g., in a kitchen), such that a user can access user interface 1812, while each of the assistant modules may be disposed throughout the kitchen at any suitable locations.
Turning to FIGS. 22 and 23, the modules (i.e., master module 1800, assistant module 1900, and/or both) of distributed ventilation system may be recirculating (such as FIG. 22), labeled 2200 or externally exhausting (such as FIG. 23), labeled 2300. A recirculating module is configured to recirculate the air back into the room after filtering. In some examples, the air is exhausted from the housing through the same portion of the gap from which the air is drawn. In other examples, the air is redirected through a different portion of the gap or directed through ductwork to another portion of the kitchen.
In the example shown in FIG. 22, air is drawn into the housing by a blower 2202 through an intake portion of the gap (e.g., gap 1810 or 1910). In some examples, a filter 2204 is disposed between the front panel and the blower (e.g., generally parallel to the front panel). Air is drawn through filter 2204 and directed by blower 2202 toward an exhaust portion of gap at the top of the module, as indicated by the arrows in FIG. 22. In some examples, the intake portion of the gap is present at least at the bottom of the module and the exhaust portion of the gap is present at least at the top of the module. In the externally exhausting example shown in FIG. 23, each of the modules include a blower 2302 configured to pull air through a filter 2304 and direct the intake air through individual ducts 2306 which collectively meet together at a single exhaust 2308 (e.g., coupled to an outside vent). The examples shown in FIGS. 22, 23 are illustrative examples of recirculating and externally exhausting configuration of modules 1800, 1900, though features of the example ventilation systems described in the previous section (e.g., filter systems, blower configurations, baffle plates, removable front panels etc.) may be utilized in any combination in modules 1800, 1900.
The blowers utilized in modules 1800, 1900 are controllable by a portion of user interface 1812. In some examples, the blowers are controlled automatically in response to signals from a cooktop and/or from external sensors built into an appliance in the kitchen. In some examples, user interface 1812 can be controlled remotely, e.g., via an external data processing system such as a smartphone or a computer.
