Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a control device of a range hood, a range hood with the control device, and a control method of the range hood according to embodiments of the present invention with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a control device of a range hood according to an embodiment of the invention. As shown in fig. 1, the control device of the range hood according to the embodiment of the present invention may include: an image acquisition module 10, an image processing module 20 and a control module 30.
Wherein, the image acquisition module 10 is used for gathering the image information of cooking utensils. The image processing module 20 is used for analyzing and processing the image information of the kitchen range to obtain the working state of the kitchen range. The control module 30 is used for performing on-off control and/or wind speed adjustment on the range hood according to the working state of the cooker.
According to one embodiment of the present invention, the image capturing module 10 may be fixedly disposed on the range hood. Wherein, image acquisition module 10 can be the camera, and the position of camera should guarantee to shoot the culinary art region of cooking utensils top, and is located the less place of oil smoke, for example, the lower part outside of top formula lampblack absorber, the panel upper portion outside of side lampblack absorber.
According to another embodiment of the present invention, the image capturing module 10 is movably disposed on the range hood. The position of the image capturing module 10 can be moved according to the actual situation.
According to an embodiment of the present invention, when the kitchen range adopts a mechanical switch, the image processing module 20 may obtain the operating state of the kitchen range by obtaining switch position information of the mechanical switch, and when the kitchen range adopts an electronic switch, the image processing module 20 may obtain the operating state of the kitchen range by obtaining display information of the electronic switch.
Specifically, the image capturing module 10, the image processing module 20, and the control module 30 may be disposed on the range hood and are in communication with each other, for example, the image capturing module 10 (e.g., a camera) may be disposed on a smoke collecting head of the range hood.
After the range hood is powered on, the range hood enters a standby mode, the image acquisition module 10 enters a real-time monitoring state, the kitchen range in the area below the range hood is subjected to real-time image acquisition, the acquired image information is sent to the image processing module 20 in a wired or wireless mode, the image processing module 20 analyzes and processes the image information of the kitchen range, the image information is compared with the image of the kitchen range in an image database, the working state of the kitchen range can be obtained, and the working state of the kitchen range is fed back to the control module 30. The control module 30 performs automatic on-off control and air speed adjustment on the range hood according to the working state of the cooker, or the control module 30 performs automatic on-off control on the range hood according to the working state of the cooker, or the control module 30 automatically adjusts the air speed of a fan of the range hood according to the working state of the cooker.
For example, when the cooker adopts a mechanical switch, the operating state of the cooker is obtained by obtaining the switch position information of the mechanical switch. Taking a knob switch as an example, as shown in fig. 2, scales are marked on the knob switch (or scales are marked on a cooking utensil panel close to the knob mechanical switch), each different scale position represents different firepower of the cooking utensil, and the firepower gradually increases along the counterclockwise direction. When the knob switch is in the first position, it indicates that no cooking event exists in the cooking area, the cooker is in a standby state, and the control module 30 controls the range hood to be in the standby state; when the knob switch is positioned at any position in the counterclockwise direction of the first position, which indicates that the cooking area has cooking time, the cooker starts to work, and the control module 30 controls the range hood to be automatically opened; when the knob switch returns to the first position, the control module 30 controls the range hood to automatically close. And the wind speed of the range hood can be adjusted according to the position of the knob switch, and each scale position shown in figure 2 corresponds to the wind speed of one fan. It should be understood that the mechanical switch may be not only a knob switch but also other switches.
When the cooker adopts the electronic switch, the working state of the cooker is obtained by obtaining the display information of the electronic switch. Taking the electronic switch shown in fig. 3 as an example, a first indicator light for displaying the on-off state is arranged on the panel of the cooker (the first indicator light emits red light to indicate that the cooker is in a standby state, and the first indicator light emits green light to indicate that the cooker is in an operating state), an indicator light for displaying different firepower (the second indicator light is on corresponding to the current firepower being in a first gear, the third indicator light is on corresponding to the current firepower being in a second gear, and the third indicator light is on corresponding to the current firepower being in a third gear), and buttons (a down button and an up button) for adjusting the firepower are arranged on the panel of the cooker. When the first indicator light emits red light, the cooking utensil is in a standby state, and the control module 30 controls the range hood to be in the standby state; when the first indicator light emits green light, the range starts to work, and the control module 30 controls the range hood to be automatically started; when the first indicator light emits red light, the control module 30 controls the range hood to be automatically closed. In addition, the current firepower (working state) of the cooker can be obtained according to the state of the indicator lamp corresponding to the firepower icon, and the control module 30 judges the current firepower according to the on-off of the indicator lamp and adjusts the air speed of the range hood fan according to the current firepower. For example, when the third indicator light is turned on, indicating that the current fire is medium, the control module 30 adjusts the wind speed of the fan to the wind speed corresponding to the medium fire.
It should be noted that the image acquisition module 10 may also be configured to acquire video information below the range hood, and the image processing module 20 processes each frame in the video information to obtain an on-off state of the kitchen range. In addition, fig. 2 and 3 are merely one specific example of the present invention.
Therefore, the control device of the range hood realizes automatic on-off and automatic air volume adjustment of the range hood by directly judging the state image of the range hood switch acquired by the image acquisition module, does not need communication between the range hood and the range, effectively solves the problems of high cost and insufficient reliability, and improves the reliability of intelligent control and the response speed of the range hood. And can confirm the culinary art state in the very first time, open range hood before the oil smoke produces, effectively solved the untimely problem of cigarette machine control.
According to an embodiment of the present invention, the image collecting module 10 is further configured to collect oil smoke image information of the cooking area, the image processing module 20 is further configured to analyze the oil smoke image information to obtain an oil smoke concentration of the cooking area, and the control module 30 is further configured to adjust a wind speed of the range hood according to the oil smoke concentration.
Specifically, when the cooking range is judged to be switched from the standby state to the working state, the range hood is automatically started, in the cooking process, the image acquisition module 10 further acquires oil smoke images of a cooking area in real time and sends the acquired oil smoke images to the image processing module 20, the image processing module 20 analyzes the oil smoke images, and the oil smoke images are compared with the images with different concentrations stored in the image database for analysis, so that the oil smoke concentration corresponding to the current image can be obtained. When the current oil smoke concentration is high, the control module 30 adjusts the wind speed of the fan to be high, and when the current oil smoke concentration is low, the control module 30 adjusts the wind speed of the fan to be low.
In another embodiment of the present invention, the control module 30 can also adjust the wind speed of the fan in combination with the working state of the cooker and the concentration of the oil smoke. Taking a knob switch as an example of a cooker, when the position information of the knob indicates that the firepower of the cooker is very large, the fact that a large amount of oil smoke is about to be generated can be judged, and the air speed of a fan can be adjusted to be large. When the position information of the knob indicates that the range has low fire and high oil smoke concentration, the control module 30 can adjust the wind speed of the fan to be high, for example, when the oil in the cooking appliance is overheated, the fan can generate large oil smoke. When the position information of the knob indicates that the fire of the stove is large and the concentration of the oil smoke is small, the control module 30 can adjust the air speed of the fan to be small, for example, water in the cooking appliance is in a non-boiling state, so that the user experience is greatly improved.
In yet another embodiment of the present invention, the control module 30 can also control the closing of the range hood in combination with the operating state of the cooktop and the soot concentration. Still take the kitchen range to adopt the knob switch as an example, when the position information of the knob indicates that the kitchen range is in the closed state and the oil smoke concentration is very small, the control module 30 controls the range hood to automatically close, thereby being capable of ensuring that the kitchen is in a better environment.
The above analysis shows that the control device of the range hood of the invention realizes the automatic control of the range hood, reduces manual operation, and effectively avoids the problems of poor kitchen environment caused by forgetting to turn on the range hood during cooking and resource waste caused by forgetting to turn off the range hood after cooking.
In summary, according to the control device of the range hood of the embodiment of the invention, the image information of the kitchen range is acquired in real time through the image acquisition module, the image information of the kitchen range is analyzed and processed through the image processing module to obtain the working state of the kitchen range, and the control module performs on-off control and/or wind speed adjustment on the range hood according to the working state of the kitchen range. From this, the device can acquire the operating condition of cooking utensils according to the image information of gathering cooking utensils to according to the operating condition of cooking utensils, realize range hood's automatic switch and/or wind speed and adjust, improved intelligent control's reliability, and can accurate timely confirm the culinary art state, open range hood before the oil smoke produces, improved user experience greatly.
Fig. 4 is a block diagram of a range hood according to an embodiment of the present invention. As shown in fig. 4, the range hood 100 according to the embodiment of the present invention may include the above-mentioned control device 110 of the range hood.
According to the range hood provided by the embodiment of the invention, the control device can acquire the working state of the kitchen range according to the image information of the collected kitchen range, and can realize automatic switching and/or wind speed adjustment of the range hood according to the working state of the kitchen range, so that the reliability of intelligent control is improved, the cooking state can be accurately and timely confirmed, the range hood is opened before oil smoke is generated, and the user experience is greatly improved.
Fig. 5 is a flowchart of a control method of a range hood according to an embodiment of the invention. As shown in fig. 5, the method for controlling a range hood according to an embodiment of the present invention may include the following steps:
and S1, acquiring the image information of the kitchen range.
Specifically, the image information of the kitchen range can be collected in real time through a camera arranged on the range hood.
And S2, analyzing and processing the image information of the cooker to acquire the working state of the cooker.
According to one embodiment of the invention, when the cooker adopts a mechanical switch, the operating state of the cooker is obtained by obtaining the switch position information of the mechanical switch. When the cooker adopts the electronic switch, the working state of the cooker is obtained by obtaining the display information of the electronic switch.
And S3, performing on-off control and/or wind speed adjustment on the range hood according to the working state of the cooker.
Specifically, after the range hood is powered on, the range hood enters a standby mode, and image information of the kitchen range can be acquired in real time through a camera arranged on a smoke collecting head of the range hood. Then, the image information of the kitchen range is analyzed and processed, and the working state of the kitchen range can be obtained by comparing the image information with the image of the kitchen range in the image database. And carrying out automatic on-off control and air speed adjustment on the range hood according to the working state of the cooker, or carrying out automatic on-off control on the range hood according to the working state of the cooker, or automatically adjusting the air speed of a fan of the range hood according to the working state of the cooker.
For example, when the cooker adopts a mechanical switch, the operating state of the cooker is obtained by obtaining the switch position information of the mechanical switch. Taking a knob switch as an example, as shown in fig. 2, scales are marked on the knob switch (or scales are marked on a cooking utensil panel close to the knob mechanical switch), each different scale position represents different firepower of the cooking utensil, and the firepower gradually increases along the counterclockwise direction. When the knob switch is in the first position, the cooking area is free of cooking events, the kitchen range is in a standby state, and the range hood is in a standby state; when the knob switch is positioned at any position in the anticlockwise direction of the first position, the cooking time in the cooking area is indicated, the cooker starts to work, and the range hood is automatically started; when the knob switch returns to the first position, the range hood is automatically closed. And the wind speed of the range hood can be adjusted according to the position of the rotary mechanical switch, and each scale position shown in figure 2 corresponds to the wind speed of a fan. It should be understood that the mechanical switch may be not only a knob switch but also other switches.
When the cooker adopts the electronic switch, the working state of the cooker is obtained by obtaining the display information of the electronic switch. Taking the electronic switch shown in fig. 3 as an example, a first indicator light for displaying the on-off state is arranged on the panel of the cooker (the first indicator light emits red light to indicate that the cooker is in a standby state, and the first indicator light emits green light to indicate that the cooker is in an operating state), an indicator light for displaying different firepower (the second indicator light is on corresponding to the current firepower being in a first gear, the third indicator light is on corresponding to the current firepower being in a second gear, and the third indicator light is on corresponding to the current firepower being in a third gear), and buttons (a down button and an up button) for adjusting the firepower are arranged on the panel of the cooker. When the first indicator light emits red light, the cooking range is in a standby state, and the range hood is in a standby state; when the first indicator light emits green light, the cooking range starts to work, and the range hood is automatically started; when the first indicator light emits red light, the range hood is automatically closed. And according to the state of the indicator lamp corresponding to the fire power icon, the current fire power (working state) of the cooker can be obtained, the current fire power is judged according to the on-off of the indicator lamp, and the air speed of the range hood fan is adjusted according to the current fire power. For example, when the third indicator light is turned on, it indicates that the current fire is medium, and the wind speed of the fan is adjusted to the wind speed corresponding to the medium fire.
Therefore, the control method of the range hood realizes automatic on-off and automatic air volume adjustment of the range hood by directly judging the state image of the range hood switch acquired by the image acquisition module, does not need communication between the range hood and the range, effectively solves the problems of high cost and insufficient reliability, and improves the reliability of intelligent control and the response speed of the range hood.

When the current oil smoke concentration is larger, the wind speed of the fan is adjusted to be larger, and when the current oil smoke concentration is smaller, the wind speed of the fan is adjusted to be smaller.
In another embodiment of the invention, the wind speed of the fan can be adjusted by combining the working state of the cooker and the concentration of oil smoke. Taking a knob switch as an example of a cooker, when the position information of the knob indicates that the firepower of the cooker is very large, the fact that a large amount of oil smoke is about to be generated can be judged, and the air speed of a fan can be adjusted to be large. When the position information of the knob indicates that the firepower of the cooker is small and the concentration of the oil smoke is high, the wind speed of the fan can be adjusted to be high, for example, when the oil smoke in the cooking utensil is hot, the large oil smoke can be generated. When the position information of the knob indicates that the fire power of the stove is large and the concentration of oil smoke is small, the air speed of the fan is adjusted to be low, and for example, water in the cooking appliance is in a non-boiling state.
In another embodiment of the invention, the closing of the range hood can be controlled by combining the working state of the cooker and the concentration of the oil smoke. Still take the kitchen range to adopt the knob switch as an example, when the position information of knob shows that the kitchen range is in the closed state, and oil smoke concentration is very little, range hood self-closing to can guarantee that the kitchen is in better environment.
