Description

COOKER HOOD AND HOUSEHOLD INTERCONNECTION CONTROL METHOD BASED ON COOKER HOOD

BACKGROUND

Technical Field The present invention relates to the field of smart home, and in particular, to a cooker hood and a household interconnection control method based on the cooker hood.

Related Art

In a daily cooking process, activities of a user are basically limited to a kitchen, especially near a cooker hood. If the user wants to control household appliances (for example, a lamp in a living room, an air conditioner, a washing machine, and the like) disposed outside the kitchen in the cooking process, the user needs to go in and out the kitchen to manually perform related operations, apparently increasing user burden and affecting user experience. In addition, when the user performs operations such as cooking in the kitchen that is a relatively enclosed environment, the user cannot timely control operating of household appliances in other rooms of a family. Once dangerous situations such as a short circuit of the household appliances happen, the user may suffer a life and property loss to a large degree.

Currently, in most cases, the user can only frequently go in and out the kitchen to turn on and off or to control the household appliances outside the kitchen, leading to inconvenience and bad user experience, which is no longer applicable to a currently popular concept of intelligently controlling the household appliances.

As shown in the related art, a current cooker hood cannot interconnect with a to-be- controlled device (for example, household appliances such as an air conditioner, an oven, a television, and the like), causing that a user in a kitchen cannot timely know operating of household appliances in other rooms of a house or remotely control these to-be-controlled devices by using the cooker hood, largely affecting user experience.

To resolve the technical problem, in the technical solutions of the embodiments of the present invention, a communications component, a user instruction receiving component, and a control component are provided in a cooker hood. A user instruction is received by using the user instruction receiving component and the cooker hood communicates with at least one to-be-controlled device by using the communications component according to the user instruction, so as to obtain state information of at least one to-be-controlled device by using the control component and/or control the to-be-controlled device.

A person of ordinary skill in the art should understand that the technical solutions of the embodiments of the present invention show state information of other household appliances in a family to a user based on small improvement on a hardware structure of the cooker hood and allow the user to control other household appliances by using the cooker hood, thus greatly optimizing user experience. Therefore, when the user performs activities in a kitchen, the user can conveniently and quickly implement intelligent and remote control to other household appliances based on the cooker hood. Further, the technical solutions of the embodiments of the present invention can strengthen a kitchen center function of the cooker hood to allow the user in the relatively isolated kitchen for a long time to know the operating of household appliances in the house without leaving the kitchen and remotely control these household appliances. To make the objectives, features, and advantages of the present invention more comprehensible, the following describes in detail the specific embodiments of the present invention with reference to the accompanying drawings.

FIG. 1 is a schematic principle diagram of a cooker hood according to a first embodiment of the present invention. Specifically, with reference to the logical block diagram shown in FIG. 2, in this embodiment, the cooker hood 1 includes a cooker hood body 11 and the cooker hood body 1 1 can include cooker hoods already in the existing technologies, which is not limited herein. More specifically, the cooker hood 1 further includes a communications component 12 communicating with a to-be-controlled device in a to-be-controlled device set, a user instruction receiving component 13 configured to receive a user instruction, and a control component 14 configured to recognize the user instruction, obtain state information of at least one to-be-controlled device that the user instruction points to by using the communications component 12, and/or control the to-be- controlled device. A person of ordinary skill in the art should understand that FIG. 1 may shown the cooker hood 1 using the embodiment of the present invention from a macroscopic view and FIG. 2 complementally describes a function operating logic of components included by the cooker hood 1 from a view of an internal circuit principle.

Preferably, the to-be-controlled device set may be predetermined by the user. For example, the user can set household appliances in different rooms of a family in the to-be- controlled device set, so that the technical solutions of the embodiments of the present invention perform intelligent and remote control to these household appliances, or the user selects a part of all household appliances to set in the to-be-controlled device set.

Preferably, the to-be-controlled device included in the to-be-controlled device set can communicate with the communications component 12. For example, for a to-be- controlled device with a function of connecting to a network, the to-be-controlled device can directly communicate with the communications component 12, or for a to-be- controlled device without the function of connecting to the network, the to-be-controlled device can communicate with the communications component 12 by coupling to an external communications component. Preferably, the to-be-controlled device with the function of connecting to the network may be household appliances configured with a wireless communications module, for example, a smart television, a computer, and the like. Further, the communications component 12 and the to-be-controlled device are connected to each other to communicate by using the network. A person of ordinary skill in the art should understand that in the technical solutions of the embodiments of the present invention, the cooker hood 1 is accessed into the network by using the communications component 12 to implement interconnection between the cooker hood 1 and the to-be-controlled device (for example, other household appliances in the family except the cooker hood), so as to provide a communication basis for the embodiments of the present invention to control the to-be-controlled device based on the cooker hood 1.

In a preferred example, the communications component 12 and the to-be-controlled device are located in a same local area network, and perform data exchange based on the local area network, where the local area network may be built by the cooker hood 1. For example, the communications component 12 includes a wireless fidelity (WIFI) communications module. The cooker hood may build the local area network based on the WIFI communications module. As a changeable example, the local area network may be built by the to-be-controlled device. For example, the to-be-controlled device is a television and the television is configured with a hotspot generating module, so that the user can pre-control the hotspot generating module of the television to build a hotspot. After the cooker hood 1 accesses to the hotspot by using the communications component 12, the cooker hood 1 and the television are located in a same local area network to perform data exchange.

As another changeable example, the local area network may be built by a third party different from the cooker hood 1 and the to-be-controlled device. For example, the user pre-installs a wireless router in the house and controls the wireless router to build a wireless local area network. After the cooker hood 1 and the to-be-controlled device respectively accesses to the wireless local area network, data exchange may be performed by using the wireless local area network as a platform.

In a changeable example of this embodiment, the communications component 12 and the to-be-controlled device may further be connected to a same cloud server (not shown in the figure), and perform data exchange by using the cloud server. For example, the cloud server dedicated to the technical solutions of the embodiments of the present invention is pre-disposed. The cooker hood 1 is connected to the cloud server by using the communications component 12, so as to perform data exchange with the to-be- controlled device also connected to the cloud server. A person of ordinary skill in the art should understand that in the technical solutions of the embodiments of the present invention, the cooker hood 1 and the to-be-controlled device are connected to each other by using the local area network or a cloud and instructions are transmitted to each of an interconnection end by using the cloud server as a transfer station to implement interconnection between the cooker hood 1 and the to-be-controlled device, so that the user can perform intelligent and remote control to the to-be-controlled device by using the cooker hood 1. As a changeable example, the cloud server may be a cloud server already in the existing technologies. When performing the technical solutions of the embodiments of the present invention, the cooker hood 1 performs data exchange with the to-be-controlled device also connected to the cloud server by using the cloud server.

Further, the user instruction receiving component 13 may present state information of each to-be-controlled device included in the to-be-controlled device set in a virtual displaying manner and determine the user instruction by actions and/or facial expressions of the user, so as to perform and remote control to the to-be-controlled device according to the user instruction.

In a preferred example, the user instruction receiving component 13 may include a projection component 131 configured to present an operation interface by means of projection and an input perception component 132 configured to obtain an operation of a user for the operation interface to determine the user instruction. For example, the projection component 131 may be a projector and the input perception component 132 may be a camera. In actual applications, the projector generates the operation interface in a form of a menu list, so as to project the state information of each to-be-controlled device included in the to-be-controlled device set to a wall. When the user browses the menu list, the camera captures the actions (for example, a gesture) and the facial expressions (for example, eyeball movement) of the user in real time to accurately determine a corresponding user instruction according to the shot user actions and implement accurate reorganization of a user intention. Further, for the cooker hood 1 configured with a display screen, the projection component 131 may be the display screen of the cooker hood 1.

Further, the user instruction receiving component 13 may further be a virtual reality (VR) device. A person of ordinary skill in the art should understand that the technical solutions of the embodiments of the present invention present the operation interface to the user by using the projection component 131 without increasing an entity display screen on the cooker hood 1 , thereby reducing complexity of production process and saving hardware costs, which is beneficial for more reasonably arranging a whole structure of the cooker hood 1. Accordingly, the operation of the user for the operation interface is accurately determined based on the input perception component 132, which is beneficial for timely responding to an operating need of the user.

In a changeable example of this embodiment, the user instruction receiving component 13 may further include an audio sensing device 134, configured to collect a speech input of the user to determine the user instruction. For example, after the user browses the operation interface presented by means of projection by using the projection component 131 , the user speaks to send an oral instruction to the cooker hood 1. The cooker hood 1 collects a speech input of the user in real time by using the audio sensing device 134 and determines the user instruction by analyzing content of speech data. A person of ordinary skill in the art should understand that the technical solutions of the embodiments of the present invention provide multiple user instruction receiving manners to satisfy various needs of different users, so as to better reflect a technical concept of an intelligent cooker hood. For example, the audio sensing device 134 may extract a key word in the collected speech input of the user and determine the user instruction by matching the key word. For another example, the audio sensing device 134 may further prerecord voiceprint data of the user and match the collected speech input with the voiceprint data when performing the technical solutions of the embodiments of the present invention, so as to avoid wrongly responding or operating.

Further, the control component 14 is further configured to receive the state information actively sent by the to-be-controlled device when entering a preset state, so as to control a latest state of the to-be-controlled device. Preferably, the preset state may be preset by the user. For example, if the user uses a washing machine to wash clothes at a balcony and needs to go to the kitchen to cook when the washing machine is still in an operating state, the user can instruct the washing machine to send the state information of ending an operation to the cooker hood 1 when the washing machine completes washing.

As a changeable example, the preset state may further refer to that a state of the to- be-controlled is changed. For example, the television can actively send the state information to the control component 14 when the television is turned on or off.

Further, the cooker hood 1 further includes a reminding component 133 responding to the state information actively sent by the to-be-controlled device. The control component 14 sends a reminder to the user by using the reminding component 133, so as to timely remind the user that the to-be-controlled device enters the preset state, or the state of the to-be-controlled is changed. Preferably, the reminding component 133 may be a horn.

A person of ordinary skill in the art should understand that if state changing of the to- be-controlled device is an unexpected change (for example, unexpectedly touching of a child) for the user, the user can timely perform a corresponding correcting program for reminding of the reminding component 133. For example, after the reminding component 133 sends the reminder to the user, the control component 14 may further control the projection component 131 to project the latest state information of the to-be-controlled device of the reminder to the user to browse. After the user sends the user instruction of changing the state of the to-be-controlled, the control component 14 controls the to-be- controlled by using the communications component 12.

Further, the communications component 12, the user instruction receiving component 13, and the control component 14 can be disposed in the cooker hood body 1 1 , for example, integrated in a control circuit of the cooker hood 1 in a form of a chip. The communications component 12, the user instruction receiving component 13, and the control component 14 can be respectively integrated on different chips, or on a same chip.

As a changeable example, the communications component 12, the user instruction receiving component 13, and the control component 14 can further be respectively connected to the cooker hood body 11 and communicate with the control component 14 of the cooker hood 1 in a wired or wireless form. For example, the communications component 12, the user instruction receiving component 13, and the control component 14 are installed on the cooker hood body 1 1 in a form of a set-top box, so that the technical solutions of the embodiments of the present invention can widely apply to any cooker hood in the existing technologies. FIG. 3 is a schematic diagram of an application scenario of a cooker hood according to a first embodiment of the present invention. Specifically, in this embodiment, the cooker hood 1 may be disposed right above a cooktop 31. The cooktop 31 may be disposed on a worktop 3.

In a typical application scenario, the cooker hood 1 communicates with a to-be- controlled device (for example, a television in a bedroom, a chandelier in a living room, and the like) in a to-be-controlled device set by using a communications component 12 and presents basic information (for example, a name or position of the to-be-controlled device) of the to-be-controlled device to a user by means of projection by using a projection component 131. The projection component 131 can present an operation interface 4 at a free position (for example, somewhere near the cooktop 31) of the worktop 3 by means of projection. The operation interface 4 presents the basic information of the to-be-controlled device.

When the user browses the operation interface 4, the cooker hood 1 obtains an operation of the user for the operation interface 4 by using an input perception component 132 to determine a user instruction (for example, a user gesture horizontally or vertically streaks through the operation interface 4 or a finger of the user stops at a local position of the operation interface 4).

In this application scenario, the user instruction determined by the input perception component 132 may be that the finger of the user stops at the local position of the operation interface 4. The input perception component 132 sends the user instruction determined by the input perception component 132 to a control component 14 to match in a preset database by using the control component 14, so as to recognize that the user instruction corresponds to a user intention to press the to-be-controlled device and obtain state information of the to-be-controlled device. For another example, the user instruction that the user horizontally streaks through the operation interface 4 may correspond to a user intention of turning a page. After recognizing that the user instruction corresponds to a user intention that the user wants to obtain the state information of the to-be-controlled device, the control component 14 obtains the state information of the to-be-controlled device by using a communications component 12 and presents on the operation interface 4 by means of projection by using the projection component 131 for the user to browse.

Further, after browsing the state information of the to-be-controlled device presented on the operation interface 4, if the user wants to change a state of the to-be-controlled device (for example, switching an air conditioner from a turn-off state to a turn-on state), the user can continue performing a gesture operation on the operation interface 4. The input perception component 132 determines the user instruction by shooting an operation of the user for the operation interface and transmits the determined user instruction to the control component 14. After the control component 14 recognizes the user instruction, the control component 14 controls the to-be-controlled device by using the communications component 12 according to the user instruction. Further, the cooker hood 1 and the to-be-controlled device in the to-be-controlled device set are located in a same local area network by using the communications component 12, or connected to a same cloud server, and perform data exchange.

As a changeable example, a user instruction receiving component 13 may further include an audio sensing device 134. The cooker hood 1 can collect a speech input of the user by using the audio sensing device 134, thus receiving the user instruction more accurately and timely.

In another typical application scenario, when the to-be-controlled device enters a preset state, updated state information may be actively sent to the cooker hood 1 based on the local area network or the cloud server. After the cooker hood 1 receives the state information actively sent by the to-be-controlled device, the control component 14 controls a reminding component 133 to send a reminder to the user, so as to timely remind the user that the to-be-controlled device already enters the preset state.

Further, the cooker hood 1 can further control the projection component 131 to automatically present the state information of the to-be-controlled device to the user by means of projection, so that the user can directly browses the to-be-controlled device entering the preset state by using the operation interface 4. A person of ordinary skill in the art should understand that a position of the communications component 12, the user instruction receiving component 13, and the control component 14 should not limit to a placement position in the figure of the present invention. A sequence of the projection component 131 , the input perception component 132, and the audio sensing device 134 that are included in the user instruction receiving component 13 may be changed to create more embodiments according to actual needs, which is not described herein.

FIG. 4 is a flowchart of a household interconnection control method based on a cooker hood according to a second embodiment of the present invention. The cooker hood may be the cooker hood 1 in the embodiments shown in FIG. 1 to FIG. 3.

Specifically, in this embodiment, first perform S101 : Receive a user instruction. More specifically, the user instruction can be sent by a user in a non-touching input manner. For example, the user may send the user instruction in manners such as a voice, a gesture, eyeball movement, and the like. Further, a user instruction receiving component 13 in the embodiment shown in FIG.

1 to FIG. 3 performs the step S101. A person of ordinary skill in the art may refer to the technical solutions of the embodiment shown in FIG. 1 to FIG. 3 to learn a related operating principle, which is not described herein.

Further, the step S101 may include: presenting an operation interface to a user by means of projection; and obtaining an operation of the user for the operation interface to determine the user instruction. For example, a projection component 131 in the embodiment shown in FIG. 1 and FIG. 2 presents the operation interface to the user by means of projection and an input perception component 132 determines the user instruction. As a changeable example, the step S101 may further include: collecting a speech input of the user to determine the user instruction. For example, an audio sensing device 134 in the embodiment shown in FIG. 1 to FIG. 3 determines the user instruction.

Next, perform S102: Obtain state information of at least one to-be-controlled device and/or control the to-be-controlled device according to the user instruction. Specifically, the at least one to-be-controlled device is included in a to-be-controlled device set. More specifically, the to-be-controlled device set may be preset by the user. For example, the to-be-controlled device set may include household appliances in a bedroom and a living room. Preferably, the to-be-controlled device and the cooker hood are connected to each other to communicate by using a network. In a preferred example, the cooker hood and the to-be-controlled device may be located in a same local area network, and perform data exchange based on the local area network. Therefore, after receiving the user instruction in the step S101 , the user instruction is recognized to determine a user intention, so as to obtain the state information of the to-be-controlled device that the user wants to browse and/or control the to-be-controlled device (for example, control the to-be- controlled device to turn on/off) according to the user instruction.

In a changeable example, the cooker hood and the to-be-controlled device may further be connected to a cloud server, and perform data exchange based on the cloud server.

Further, a control component 14 in the embodiment shown in FIG. 1 to FIG. 3 performs the step S102. A person of ordinary skill in the art may refer to the technical solutions of the embodiment shown in FIG. 1 to FIG. 3 to learn a related operating principle, which is not described herein.

A changeable example of this embodiment may further include a step: Receive the state information actively sent by the to-be-controlled device when entering a preset state. For example, the to-be-controlled device may be an oven. The user uses the oven to cook food in advance. After the oven completes a cooking action (for example, a timer returns to zero), the cloud server may update the state information of the oven and send latest state information of the oven to the cooker hood.

Further, a reminder is sent to the user in response to the state information actively sent by the to-be-controlled device. For example, after the cooker hood receives the latest state information of the oven, the cooker hood may remind the user by using an internal horn and may further present the latest state information of the oven to the user to browse by means of projection.

In another changeable example of this embodiment, the user instruction is selected from a candidate instruction set and the candidate instruction set includes at least one candidate instruction, where different candidate instructions point to different to-be- controlled device groups; and the to-be-controlled device groups include one or more to- be-controlled devices in a to-be-controlled device set. For example, the user can preset multiple to-be-controlled devices in a same room as a same to-be-controlled device group (for example, a television, an air conditioner, and a chandelier in the bedroom are set as a to-be-controlled device group) and can further preset a candidate instruction corresponding to the to-be-controlled device group, so as to control all to-be-controlled devices in the to-be-controlled device group by using only one user instruction.

For example, the user can set a lamp, a television, and an air purifier in a dining room as a to-be-controlled device group (referred to as a to-be-controlled device group of the dining room in the following). After the user completes cooking in a kitchen, the user can select a candidate instruction pointing to the to-be-controlled device group of the dining room from a candidate instruction set, so as to remotely turn on the lamp, the television, and the air purifier in the dining room by using the cooker hood.

FIG. 5 is a flowchart of a household interconnection control method based on a cooker hood according to a third embodiment of the present invention. The cooker hood may be the cooker hood 1 in the embodiments shown in FIG. 1 to FIG. 3.

Specifically, in this embodiment, first perform S201 : Present an operation interface by means of projection. For example, the operation interface is presented on a wall opposite to the cooker hood 1 by means of projection based on a projection component 131.

Next, perform S202: Obtain an operation of a user for the operation interface to determine a user instruction. For example, a finger of the user streaks on a left side through a display area of the operation interface. An input perception component 132 senses the operation of the user by shooting or thermal imaging.

Next, perform S203: Obtain state information of at least one to-be-controlled device and/or control the to-be-controlled device according to the user instruction. Specifically, a person of ordinary skill in the art may refer to the step S102 in the embodiment shown in FIG. 4, which is not described herein. For example, a control component 14 recognizes the determined user instruction in the step S202 and determines that an action that the finger of the user streaks on the left side through the display area corresponds to a user instruction of turning a page to the left side by comparing with a preset database, so as to control the projection component 131 to display information of one or more to-be- controlled devices ranking after at least one to-be-controlled device currently displayed.

In a changeable example, after performing the step S203, step S204 may further be performed: Receive the state information actively sent by the to-be-controlled device when entering a preset state. Further, perform step S205: Send a reminder to the user in response to the state information actively sent by the to-be-controlled device. Specifically, a person of ordinary skill in the art may refer to a description of a reminding component 133 in FIG. 1 to FIG. 4, which is not described herein.

A person of ordinary skill in the art should understand that the step S204 and the step S205 may further be performed before the step S201. After sending the reminder to the user, the state information of the to-be-controlled device is actively presented to the user by means of projection, so that the user can more conveniently control the to-be- controlled device entering the preset state.

FIG. 6 is a flowchart of a household interconnection control method based on a cooker hood according to a fourth embodiment of the present invention. The cooker hood may be the cooker hood 1 in the embodiments shown in FIG. 1 to FIG. 3.

Specifically, in this embodiment, first perform S301 : Present an operation interface by means of projection.

Next, perform S302: Collect a speech input of a user to determine the user instruction. For example, an audio signal in a kitchen is collected in real time by using an audio sensing device 134, so as to timely and accurately obtain the speech input of the user to determine the user instruction.

Next, perform S303: Obtain state information of at least one to-be-controlled device and/or control the to-be-controlled device according to the user instruction. Specifically, a person of ordinary skill in the art may refer to the step S102 in the embodiment shown in FIG. 4, which is not described herein.

As a changeable example, after performing the step S302 and/or before performing the step S301 , the step S204 and the step S205 in the embodiment shown in FIG. 5 may be further performed, so as to timely remind the user that the to-be-controlled device enters a preset state. A person of ordinary skill in the art may understand that all or some of the steps of the methods in the embodiments may be implemented by a program instructing relevant hardware. The program may be stored in a computer readable storage medium. The storage medium may include: a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disc.

As disclosed above, the present invention is not limited herein. Any person of ordinary skill in the art may make any variation and modification without departing from the spirit and principle of the present invention. Therefore, the protection scope of the present invention shall fall within the limited scope of claims.
