The present subject matter relates generally to ventilation systems, and more particularly to operating ventilation systems according to recommendations.
Many households contain systems or assemblies for providing air circulation or ventilation to select rooms or areas. For instance, kitchen appliances such as ovens, microwaves, cooktops, or the like include ventilation systems, such as range hoods to selectively circulate air through the kitchen during or after cooking operations. Moreover, many bathrooms include circulation fans to reduce humidity or condition the air within the bathroom. Additional or alternative appliances may include circulation or ventilation systems, which typically include an air handler and one or more control systems.
However, existing ventilation systems and applications have certain drawbacks. For one example, a user is required to manually activate the air handler to initiate a ventilation cycle or operation. Accordingly, the ventilation cycle may not be performed during times when air quality is low, due to a lack of recognition from the user. For another example, some existing ventilation systems are activated automatically according to a preset trigger. Accordingly, the ventilation cycle may be performed unnecessarily, resulting in discomfort due to noise or a waste of electricity.
Accordingly, a ventilation system which obviates one or more of the above-mentioned drawbacks would be beneficial. In particular, a ventilation system including finely tuned activation points and user interaction would be useful.
Aspects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
In one exemplary aspect of the present disclosure, a ventilation system is provided. The ventilation system may include a casing defining a receiving space and an air outlet; an air handler positioned within the casing and configured to motivate an airflow through the air outlet to condition a room; and a controller operably coupled with the air handler, the controller configured to perform an operation. The operation may include detecting a plurality of characteristics of ambient air within the room; determining that at least one characteristic of the plurality of characteristics is outside of a predetermined range; emitting a notification to a user in response to determining that the at least one characteristic is outside of the predetermined range, wherein the notification includes a recommendation to perform a conditioning cycle; and receiving a command to initiate the conditioning cycle, wherein the conditioning cycle includes activating the air handler.
In another exemplary aspect of the present disclosure, a method of operating a ventilation system provided within a room is provided. The ventilation system may include a casing and an air handler positioned within the casing. The method may include detecting a plurality of characteristics of ambient air within the room; determining that at least one characteristic of the plurality of characteristics is outside of a predetermined range; emitting a notification to a user in response to determining that the at least one characteristic is outside of the predetermined range, wherein the notification includes a recommendation to perform a conditioning cycle; and receiving a command to initiate the conditioning cycle, wherein the conditioning cycle includes activating the air handler.

Turning to the figures,
As shown in
Range 104 may include a chassis or cabinet 110 that extends along the vertical direction V between a top portion 112 and a bottom portion 114; along the lateral direction L between a left side portion and a right side portion; and along the traverse direction T between a front portion and a rear portion. Range 104 may include a cooktop surface 116 having one or more heating elements 118 (two shown) for use in, for example, heating or cooking operations. In exemplary embodiments, cooktop surface 116 is constructed with ceramic glass. In other embodiments, however, cooktop surface 116 may include another suitable material, such as a metallic material (e.g., steel) or another suitable non-metallic material. Heating elements 118 may be various sizes and may employ any suitable method for heating or cooking an object, such as a cooking utensil (not shown), and its contents.
In some embodiments, range 104 includes an insulated cabinet 110 that defines a cooking chamber 120 selectively covered by a door 122. One or more heating elements (not shown, e.g., top broiling elements or bottom baking elements) may be enclosed within cabinet 110 to heat cooking chamber 120. Heating elements within cooking chamber 120 may be provided as any suitable element for cooking the contents of cooking chamber 120, such as an electric resistive heating element, a gas burner, a microwave element, a halogen element, etc. Thus, cooktop appliance 104 may be referred to as an oven range appliance. As will be understood by those skilled in the art, cooktop appliance or range 104 is provided by way of example only, and the present subject matter may be used in the context of any suitable cooking appliance, such as a double oven range appliance or a standalone cooktop (e.g., fitted integrally with a surface of a kitchen counter). Thus, the example embodiments illustrated in figures are not intended to limit the present subject matter to any particular cooking chamber or heating element configuration, except as otherwise indicated.
As illustrated, a user interface (or user interface panel) 126 may be provided on range 104. Although shown at front portion of range 104, another suitable location or structure (e.g., a backsplash) for supporting user interface panel 126 may be provided in alternative embodiments. In some embodiments, user interface panel 126 includes input components or controls 128, such as one or more of a variety of electrical, mechanical, or electro-mechanical input devices. Controls 128 may include, for example, rotary dials, knobs, push buttons, and touch pads. A controller 130 is in communication with user interface panel 126 and controls 128 through which a user may select various operational features and modes and monitor progress of range 104. In additional or alternative embodiments, user interface panel 126 includes a display component 132, such as a digital or analog display in communication with a controller 130 and configured to provide operational feedback to a user. In certain embodiments, user interface panel 126 represents a general purpose I/O (“GPIO”) device or functional block.
As shown, controller 130 is communicatively coupled (i.e., in operative communication) with user interface panel 126, controls 128, and display 132. Controller 130 may also be communicatively coupled with various operational components of range 104 as well, such as heating elements (e.g., 118), sensors, etc. Input/output (“I/O”) signals may be routed between controller 130 and the various operational components of range 104. Thus, controller 130 may selectively activate and operate these various components. Various components of range 104 are communicatively coupled with controller 130 via one or more communication lines such as, for example, conductive signal lines, shared communication busses, or wireless communications bands.
In some embodiments, controller 130 includes one or more memory devices and one or more processors. The processors can be any combination of general or special purpose processors, CPUs, or the like that can execute programming instructions or control code associated with operation of range 104. The memory devices (i.e., memory) may represent random access memory such as DRAM or read only memory such as ROM or FLASH. In one embodiment, the processor executes programming instructions stored in memory. The memory may be a separate component from the processor or may be included onboard within the processor. Alternatively, controller 130 may be constructed without using a processor, for example, using a combination of discrete analog or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software.
In certain embodiments, controller 130 includes a network interface such that controller 130 can connect to and communicate over one or more networks with one or more network nodes. Controller 130 may also include one or more transmitting, receiving, or transceiving components for transmitting/receiving communications with other devices communicatively coupled with range 104. Additionally, or alternatively, one or more transmitting, receiving, or transceiving components can be located off board controller 130. Generally, controller 130 may be positioned in any suitable location throughout range 104. For example, controller 130 may be located proximate to user interface panel 126 toward front portion of range 104. In optional embodiments, controller 130 is in operable communication with a controller 130 (described below) of microwave appliance 102 (e.g., through one or more wired or wireless channels).
Referring still to
Microwave appliance 102 may further include or be in operative communication with a processing device or a controller 142 that may be generally configured to facilitate appliance operation.

Additionally or alternatively, controller 142 may be constructed without using a microprocessor, e.g., using a combination of discrete analog and/or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND/OR gates, and the like) to perform control functionality instead of relying upon software.
Controller 142 may include, or be associated with, one or more memory elements or non-transitory computer-readable storage mediums, such as RAM, ROM, EEPROM, EPROM, flash memory devices, magnetic disks, or other suitable memory devices (including combinations thereof). These memory devices may be a separate component from the processor or may be included onboard within the processor. In addition, these memory devices can store information and/or data accessible by the one or more processors, including instructions that can be executed by the one or more processors. It should be appreciated that the instructions may be software written in any suitable programming language or can be implemented in hardware. Additionally, or alternatively, the instructions may be executed logically and/or virtually using separate threads on one or more processors.
For example, controller 142 may be operable to execute programming instructions or micro-control code associated with an operating cycle of appliance 102. In this regard, the instructions may be software or any set of instructions that when executed by the processing device, cause the processing device to perform operations, such as running one or more software applications, displaying a user interface, receiving user input, processing user input, etc. Moreover, it should be noted that controller 142 as disclosed herein is capable of and may be operable to perform any methods, method steps, or portions of methods as disclosed herein. For example, in some embodiments, methods disclosed herein may be embodied in programming instructions stored in the memory and executed by controller 142.
The memory devices may also store data that can be retrieved, manipulated, created, or stored by the one or more processors or portions of controller 142. The data can include, for instance, data to facilitate performance of methods described herein. The data can be stored locally (e.g., on controller 142) in one or more databases and/or may be split up so that the data is stored in multiple locations. In addition, or alternatively, the one or more database(s) can be connected to controller 142 through any suitable network(s), such as through a high bandwidth local area network (LAN) or wide area network (WAN). In this regard, for example, controller 142 may further include a communication module or interface that may be used to communicate with one or more other component(s) of microwave appliance 102, controller 142, an external appliance controller, or any other suitable device, e.g., via any suitable communication lines or network(s) and using any suitable communication protocol. The communication interface can include any suitable components for interfacing with one or more network(s), including for example, transmitters, receivers, ports, controllers, antennas, or other suitable components.
As noted above, microwave appliance 102 may be positioned or mounted above range 104 (e.g., as an OTR microwave). Specifically, a cabinet 150 of OTR microwave appliance 102 may be positioned above range 104 along the vertical direction V.
In embodiments, the cabinet 150 may be an insulated cabinet. As shown, cabinet 150 of microwave appliance 102 includes a plurality of outer walls and when assembled, microwave appliance 102 generally extends along the vertical direction V between a top end 152 and a bottom end 154; along the lateral direction L between a first side end 156 and a second side end 158; and along the transverse direction T between a front end and a rear end. In particular, cabinet 150 comprises first exterior side panel 176 at first side 156 laterally spaced from second external side panel 178 at second side 158, a front panel 180, a back panel 182, and a top panel 184 (
In some embodiments, cabinet 150 is spaced apart from cooktop surface 116 along the vertical direction V. An open region 164 may thus be defined along the vertical direction V between cooktop surface 116 and bottom end 154 of cabinet 150. Although a generally rectangular shape is illustrated, any suitable shape or style may be adapted to form the structure of cabinet 150. Within cabinet 150, an internal liner of cabinet 150 defines a cooking chamber 166 for receipt of food items for cooking.
A microwave oven enclosure 162 may be supported within cabinet 150. Microwave oven enclosure 162 comprises a first side wall 190 laterally spaced from the first external side panel 176. The first side wall 190 defines a first fan inlet 192 formed as an opening in the first side wall 190. As illustrated, the first fan inlet 192 may be formed by removing a portion of the first side wall 190. In other embodiments, the first fan inlet 192 may be a series of smaller openings, for example holes or slots, formed in the first side wall 190 to allow a flow of air to pass.
Microwave oven enclosure 162 comprises a second side wall 194 laterally spaced from the second external side panel 178. The second side wall 194 also defines a fan inlet, second fan inlet 196 formed, as above, as an opening in the second side wall 194. Also as above, the second fan inlet 196 may be formed by removing a portion of the second side wall 194 or, in some embodiments, may be a series of smaller openings, for example holes or slots, formed in the second side wall 194 to allow a flow of air to pass. The microwave oven enclosure 162 may also comprise a bottom panel 198 joining the first side wall 190 and the second side wall 194 at a lower end of each wall.
Microwave appliance 102 is generally configured to heat articles (e.g., food or beverages) within cooking chamber 166 using electromagnetic radiation. Microwave appliance 102 may include various components which operate to produce electromagnetic radiation, as is generally understood. For example, microwave appliance 102 may include a heating assembly 168 in mechanical space 200, the heating assembly 168 having a magnetron (e.g., a cavity magnetron), a high voltage transformer, a high voltage capacitor, and a high voltage diode, as is understood. The transformer may provide energy from a suitable energy source (such as an electrical outlet) to the magnetron. The magnetron may convert the energy to electromagnetic radiation, specifically microwave radiation. The capacitor generally connects the magnetron and transformer, such as via high voltage diode, to a chassis. Microwave radiation produced by the magnetron may be transmitted through a waveguide to cooking chamber 166.
The structure and intended function of microwave ovens or appliances are generally understood by those of ordinary skill in the art and are not described in further detail herein.
Microwave appliance 102 may include a door assembly 170 that is movably mounted (e.g., rotatably attached) to cabinet 150 in order to permit selective access to cooking chamber 166. Specifically, door assembly 170 may move between an open position (not pictured) and a closed position (e.g.,
Kitchen hub 100 may include a ventilation system 202. Ventilation system 202 may include an air handler (or fan) 212. For instance, air handler 212 may be provided within microwave appliance 102. As such, microwave appliance 102 may be referred to as a casing of air handler 212. However, according to additional or alternative embodiments, air handler 212 may be positioned within a separate and distinct casing 203 (e.g., schematically shown in
As described above and illustrated at least in
First exhaust path 208 and second exhaust path 210 may be in fluid communication with air handler (or fan) 212 mounted in cabinet 150. As illustrated, air handler 212 may be positioned adjacent to the back panel 182 of cabinet 150. For instance, air handler 212 may be positioned or accommodated within casing 203 (
According to the illustrated exemplary embodiment, air handler 212 is an axial fan positioned within casing 151. However, it should be appreciated that according to alternative embodiments, air handler 212 may be positioned at any other suitable location and may be any other suitable fan type, such as a tangential fan, a centrifugal fan, etc.
In addition, according to an exemplary embodiment, air handler 212 is a variable speed fan such that it may rotate at different rotational speeds, thereby generating different air flow rates. In this manner, the amount of air circulated through exhaust 218 may be continuously and precisely regulated. Moreover, by pulsing the operation of air handler 212 or throttling air handler 212 between different rotational speeds, the flow of air through exhaust 218 may have a different flow velocity or may generate a different flow pattern within cabinet 150.
Kitchen hub 100 may further include a sensor 220 (e.g., in electrical or wireless communication with controller 130,
Sensor 220 may sense the air-quality characteristic within the external atmosphere 216 after a cooking cycle, during a cooking cycle, or at any predetermined time. The air-quality characteristic may include total volatile organic compounds (tVOC) or equivalent carbon dioxide (eCO2), for example. Sensor 220 may be configured to measure any suitable air-quality characteristic, and the disclosure is not limited to those mentioned herein. Additionally or alternatively, a plurality of sensors 180 may be provided to measure multiple air-quality characteristics (e.g., temperature, humidity, carbon monoxide [CO], smoke, etc.).
Referring back to
For example, external communication system 300 permits controller 130 of kitchen hub 100 to communicate with a separate device external to kitchen hub 100, referred to generally herein as an external device 302. As described in more detail below, these communications may be facilitated using a wired or wireless connection, such as via a network 304. In general, external device 302 may be any suitable device separate from kitchen hub 100 that is configured to provide and/or receive communications, information, data, or commands from a user. In this regard, external device 302 may be, for example, a personal phone, a smartphone, a tablet, a laptop or personal computer, a wearable device, a smart home system, or another mobile or remote device.
In addition, a remote server 306 may be in communication with kitchen hub 100 and/or external device 302 through network 304. In this regard, for example, remote server 306 may be a cloud-based server 306, and is thus located at a distant location, such as in a separate state, country, etc. According to an exemplary embodiment, external device 302 may communicate with a remote server 306 over network 304, such as the Internet, to transmit/receive data or information, provide user inputs, receive user notifications or instructions, interact with or control kitchen hub 100, etc. In addition, external device 302 and remote server 306 may communicate with kitchen hub 100 to communicate similar information.
In general, communication between kitchen hub 100, external device 302, remote server 306, and/or other user devices or appliances may be carried using any type of wired or wireless connection and using any suitable type of communication network, non-limiting examples of which are provided below. For example, external device 302 may be in direct or indirect communication with kitchen hub 100 through any suitable wired or wireless communication connections or interfaces, such as network 304. For example, network 304 may include one or more of a local area network (LAN), a wide area network (WAN), a personal area network (PAN), the Internet, a cellular network, any other suitable short-or long-range wireless networks, etc. In addition, communications may be transmitted using any suitable communications devices or protocols, such as via Wi-Fi®, Bluetooth®, Zigbee®, wireless radio, laser, infrared, Ethernet type devices and interfaces, etc. In addition, such communication may use a variety of communication protocols (e.g., TCP/IP, HTTP, SMTP, FTP), encodings or formats (e.g., HTML, XML), and/or protection schemes (e.g., VPN, secure HTTP, SSL).
External communication system 300 is described herein according to an exemplary embodiment of the present subject matter. However, it should be appreciated that the exemplary functions and configurations of external communication system 300 provided herein are used only as examples to facilitate description of aspects of the present subject matter. System configurations may vary, other communication devices may be used to communicate directly or indirectly with one or more associated appliances, other communication protocols and steps may be implemented, etc. These variations and modifications are contemplated as within the scope of the present subject matter.
Referring now to
At step 402, method 400 may include detecting a plurality of characteristics of ambient air within a room. In detail, method 400 may be initiated at any suitable time, such as during a cooking or heating operation (e.g., with respect to kitchen hub 100). A sensor (e.g., sensor 220) may be activated or otherwise initiated to begin sensing the characteristics within the room (e.g., kitchen, bathroom, etc.). As mentioned above, the plurality of characteristics may include a tVOC level, an eCO2 level, a smoke level or concentration, a humidity level, a moisture level, a CO level, or the like. Accordingly, two or more sensors may be incorporated to detect and monitor each of the plurality of characteristics.
The sensor or sensors may continually monitor the ambient air to detect changes in one or more of the plurality of characteristics. For instance, the sensor may be in an “always on” state, comparing current levels of the plurality of characteristics to predetermined levels. In additional or alternative embodiments, the sensor may be programmed to perform readings or measurements at predetermined intervals (e.g., every 10 seconds). As described above, the sensor may be operably coupled with a controller (e.g., controller 130) to which the readings or detections are then sent.
At step 404, method 400 may include determining that at least one characteristic of the plurality of characteristics is outside of a predetermined range. For instance, during the measurement cycle, method 400 may determine (e.g., according to the received data from the sensor) that at least one characteristic of the plurality of characteristics is abnormal (e.g., outside of the normal range). An abnormal characteristic may include a high level of tVOC, a high level of CO, a high concentration of smoke, a high moisture level, or the like. In some instances, the abnormality may be a low level of the respective characteristic.
According to some embodiments, determining that the at least one characteristic is outside of the predetermined range includes determining that the at least one characteristic has reached a predetermined threshold. As mentioned, the abnormality may be a high level of the at least one characteristic. Accordingly, a user may define a threshold at which the characteristic is determined to be abnormal. In some instances, the threshold is predetermined (e.g., set during manufacturing or by a seller). Thus, the at least one characteristic may be determined to be outside of the predetermined range when the threshold (e.g., concentration of the characteristic) is crossed.
At step 406, method 400 may include emitting a notification to a user in response to determining that the at least one characteristic is outside of the predetermined range. In detail, method 400 may provide a notification or alert to notify a user as to the air quality within the room. The notification may be emitted via a user interface (e.g., user interface panel 126). For instance, the notification may be presented on a display of the user interface. Additionally or alternatively, the notification may be provided to a remote device (e.g., external device 302) such as a smartphone, tablet, wearable, or the like. For instance, method 400 may include establishing a remote connection with the remote device (e.g., via a local network). The notification may then be sent to the remote device via the network. The notification may include a textual or visual notification (e.g., such as a string of words presenting the notification) along with an audible notification (e.g., such as an alarm, a buzzer, or the like).
The notification may include one or more recommendations. In detail, the notification may alert the user as to the status of the air currently within the room (e.g., kitchen, bathroom, etc.). The notification may thus include an analysis of the at least one characteristic (or each of the plurality of characteristics). For one example, the notification may present a current reading including the current levels of each of the plurality of characteristics. The notification may show the levels as compared to the normal levels (e.g., as part of a range or as compared to the threshold). Additionally or alternatively, the notification may include educational pointers on the characteristics which are currently measuring as abnormal. Advantageously, the user may be informed as to preferred levels and air quality standards as the air quality event unfolds.
According to some embodiments, the notification includes a recommendation to perform a conditioning cycle. In detail, method 400 may determine that the at least one characteristic is at a predetermined level such that the conditioning cycle would improve the air quality to an optimal degree. For instance, method 400 may determine that the moisture level of the ambient air is above the threshold (or outside of the predetermined range) and determine that the conditioning cycle would benefit the user in comfort and functionality. The notification may thus inform the user that the conditioning cycle is recommended to improve the quality of the air.
At step 408, method 400 may include receiving a command to initiate the conditioning cycle. Upon emitting the notification to the user, the appliance may wait to receive the initiation command before initiating any conditioning operation. Accordingly, the appliance may refrain from automatically activating any elements (e.g., such as the air handler) to perform the conditioning operation. The command (e.g., initiation command) may be performed or input by the user. For instance, the user may decide that the conditioning cycle is required (or desired) and may initiate the conditioning cycle (e.g., via the user input or via the connected remote device).
The conditioning cycle may include activating the air handler. As described above, the air handler may be a variable speed air handler or fan capable of operating (e.g., rotating) at a plurality of speeds to produce varying airflows. Thus, the initiation of the conditioning cycle may include activating the air handler at a first predetermined speed. The first predetermined speed may depend on the at least one characteristic which is outside of the predetermined range, the amount to which the at least one characteristic is outside of the predetermined range, a number of characteristics which are outside of the predetermined range, a combination of factors, or the like. Moreover, the first predetermined speed may depend on a time of day, a time of year, or the like. Further still, the first predetermined speed may depend on an operation of additional connected devices (e.g., a central air conditioning unit within the structure). Thus, the conditioning cycle may be initiated according to an input by the user after having provided the notification to the user regarding the air quality.
Method 400 may include determining a corresponding recommended trigger point to initiate the conditioning cycle. For instance, a plurality of recommended trigger points may be determined, each respectively matched with one of the plurality of characteristics. For one example, a smoke level or concentration within the ambient air may have a first recommended trigger point (e.g., above a predetermined parts per million [ppm]). The recommended trigger point may thus be a threshold. The recommended trigger point may thus include the recommendation to initiate the conditioning cycle. The recommended trigger points may be determined before an air quality event takes place. For instance, upon an initial set up of the appliance (e.g., kitchen hub, microwave, bathroom fan, etc.), the operating system of the appliance may provide the prompt to the user to set the trigger points (e.g., according to the recommendations). Accordingly, in subsequent air quality events, the appliance may determine an activation point according to the preselected and preset trigger points.
Method 400 may include presenting a list of each of the corresponding recommended trigger points to the user. For instance, the list may be presented on the user interface of the appliance. Additionally or alternatively, the list may be forwarded or sent to the remote device (e.g., in remote communication with the appliance). The user may then select to incorporate one or more of the recommended trigger points. When a corresponding recommended trigger point is selected, method 400 may store the selection within an on-board memory. Subsequently, when the selected trigger point is reached in the future, the appliance may perform a predetermined response (e.g., as a response to the at least one characteristic reaching the stored trigger point). Thus, the user may select a trigger point only according to one or some of the plurality of characteristics (e.g., smoke level, CO level, etc.). The conditioning cycle will not automatically initiated if another (e.g., unselected) characteristic is triggered in future operations.
For one example, method 400 may include prompting the user to set an automatic response (e.g., after emitting the notification to the user at step 406). The prompt may include a request to automatically initiate the conditioning cycle when at least one of the characteristics reaches the stored recommended trigger. The user may then respond to the prompt (or request) in the affirmative to set the automatic response. Accordingly, method 400 may include receiving a command to establish the automatic response. From here, method 400 may include storing the automatic response after receiving the command. As mentioned, the automatic response may include initiating the air handler at a predetermined speed. According to some embodiments, the predetermined speed may be the first predetermined speed, a second predetermined speed, or the like. Accordingly, the conditioning cycle may be initiated upon determining that at least one characteristic of the plurality of characteristics is outside of the predetermined range.
