[0072] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] Option 1

[0074] This invention provides a stove system, such as Figures 1-3 , Figure 9 As shown, the stove system includes: a gas stove 200, a switch device 21, and a sensor device 100. The switch device 21 is used to control the on / off state of the gas intake of the gas stove 200 at least; the sensor device 100 is used to detect abnormal states of the gas stove 200 at least; when the gas stove 200 is in an abnormal state, the sensor device 100 and / or the controller 201 of the gas stove control the switch device 21 to operate.

[0075] The heat generated by the gas stove 200 is transferred to the food. The sensor 100 detects the status of the gas stove 200. When an abnormal state occurs, the signal from the sensor 100 is transmitted directly or indirectly to the switch 21. The switch 21 acts according to the received signal, cutting off or reducing the gas intake to stop the flame or reduce the flame, thereby realizing automated control of the working status of the gas stove 200, preventing the abnormal state from worsening, achieving reliable and accurate safety monitoring, which helps to ensure the safety of the cooking process, promotes the automation and intelligence of cooking, and improves cooking efficiency.

[0076] After receiving the control signal, the switch device 21 will activate. The control signal can be issued by the controller 201 of the gas stove or directly by the sensor 100. For example, the sensor 100 has its own controller. The controller of the sensor 100 processes the detected status signal and communicates with the switch device 21 through the communication module to directly transmit the control signal to the switch device 21 to control the switch device 21 to cut off or reduce the gas intake.

[0077] In one embodiment, a switch device 21 is disposed on the gas inlet pipe 27 of the gas stove 200; a sensing device 100 is used to communicate directly or indirectly with the controller 201 of the gas stove based on a detected abnormal state of the gas stove 200, so that the controller 201 of the gas stove controls the switch device 21 to operate. The controller 201 of the gas stove sends a control signal to the switch device 21 according to the received signal, so as to control the switch device 21 to cut off or open the gas inlet pipe 27, or adjust the gas intake volume of the gas inlet pipe 27, so as to realize the gas stove 200 to stop ignition or adjust the flame size.

[0078] Furthermore, such as Figure 9 As shown, the sensing device 100 includes a first communication module 101, and the gas stove controller 201 includes a second communication module 202. The sensing device 100, based on detected abnormal conditions of the gas stove 200, communicates directly or indirectly with the second communication module 202 via the first communication module 101, so that the gas stove controller 201 controls the switching device 21 to operate. The signal detected by the sensing device 100 is transmitted directly or indirectly to the second communication module 202 via the first communication module 101, and the gas stove controller 201 sends a control signal to the switching device 21 based on the received signal.

[0079] The gas inlet pipe 27 includes an outer pipe 271 located outside the housing of the gas stove 200 and an inner pipe 272 located inside the housing of the gas stove 200, such as... Figure 3 As shown, the outer pipe 271 is connected to the inner pipe 272, and the gas stove 200 is connected to the city gas supply pipeline through the outer pipe 271. Gas flows through the inner pipe 272 to the switch of the gas stove 200. The switch is connected to the burner 22 through the gas guide pipe 28. The switch is used to control the ignition of the burner 22 and control the gas to enter the gas guide pipe 28. The switch device 21 can be installed on the outer pipe 271 or the inner pipe 272.

[0080] Preferably, the switch device 21 is located inside the housing of the gas stove 200, that is, the switch device 21 is installed in the inner tube 272, so as to integrate the switch device 21 into the gas stove 200, making it convenient for the gas stove 200 to be installed in the kitchen. During installation, it is not necessary to connect and fix the switch device 21 again; it is only necessary to connect the gas inlet pipe 27 to the city gas supply pipe. Specifically, the switch device 21 can be a solenoid valve.

[0081] In one embodiment, the sensing device 100 and the gas stove 200 are independently and separately arranged. The sensing device 100 and the gas stove 200 are independent structures that can be molded separately, eliminating the need for a mechanical connection and assembly. In use, the sensing device 100 is positioned appropriately to detect abnormal conditions of the gas stove 200, ensuring communication between the sensing device 100 and the gas stove 200. Specifically, in use, the sensing device 100 can be placed on the gas stove 200 or on other objects nearby. The sensing device 100 offers flexible placement and is compatible with existing gas stoves 200, enabling communication between the sensing device 100 and the existing gas stove 200, thus forming the stove system provided by this invention.

[0082] like Figure 1 and Figure 4 As shown, the gas stove 200 includes a burner 22. A switch 26 for controlling the operation of the burner is provided on the front side of the burner 22. The sensor 100 is located on the rear side of the burner 22. The front side of the burner 22 is the operating side. Users usually stand on the front side of the burner 22. This arrangement can avoid the sensor 100 interfering with the user's operation and ensure that the sensor 100 is not blocked by the user or other utensils on the stove 24. This is conducive to the sensor 100 reliably detecting abnormal conditions of the gas stove 200.

[0083] The burner 22 is arranged along the transverse line 25, meaning the center of the burner 22 is located at the transverse line 25. In one embodiment, as... Figure 4 As shown, the front side of the horizontal line 25 is the front side of the burner 22, and the rear side of the horizontal line 25 is the rear side of the burner 22. In one embodiment, the rear area of ​​the burner 22 is entirely located behind the burner 22 itself, excluding the area between the rear boundary of the burner 22 and the horizontal line 25. In this embodiment, the arrangement range of the sensing device 100 is reduced, which helps to improve the stability and reliability of the sensing device 100 in detecting abnormal states of the gas stove 200.

[0084] Furthermore, there are multiple burners 22, distributed along the horizontal line 25. The angle between the line connecting the sensing device 100 and the center of each burner 22 and the horizontal line 25 is denoted as A, where A≠0. That is, the centers of the sensing device 100 and the multiple burners 22 are offset and not on the same straight line. The sensing device 100 can simultaneously detect multiple burners 22. When at least one burner 22 malfunctions, the sensing device 100 communicates directly or indirectly with the gas stove controller 201, causing the gas stove controller 201 to control the switching device 21 to operate. Figure 4 As shown, the included angle A is the angle at which the line connecting the center of the sensing device 100 and the center of the burner 22 turns counterclockwise to the horizontal line 25. Preferably, 10°≤A≤150°, which can ensure that the sensing device 100 can detect multiple burners 22 at the same time and avoid the nearby burners 22 and the cooking utensils above them from blocking the distant burners 22. More preferably, 15°≤A≤150°.

[0085] Preferably, such as Figure 1 As shown, the sensing device 100 is located on the left rear side or right rear side of the burner 22. On the one hand, this avoids the sensing device 100 from interfering with the user's operation and ensures that the sensing device 100 is not blocked by the user or other utensils on the stove 24. On the other hand, it facilitates the sensing device 100 to detect multiple burners 22 at the same time, avoiding the nearby burners 22 and the cooking utensils above them from blocking the distant burners 22. This is conducive to the sensing device 100's stable and reliable detection of multiple gas stoves 200.

[0086] Cooking utensils are usually placed on the pot rack 23. Considering that cooking utensils such as pots and pans are generally large, in one embodiment, the height of the sensing device 100 is not higher than the height of the pot rack 23 of the gas stove 200, so as to avoid the detection range of the sensing device 100 being blocked by the cooking utensils and to ensure that the sensing device 100 can detect the area of ​​the burner 22 and the pot rack 23.

[0087] Furthermore, the distance between the sensing device 100 and the center of the burner 22 is no more than 1.5 meters, ensuring that the sensing device 100 can accurately detect the area near the center of the burner 22 and improving the detection sensitivity.

[0088] In one embodiment, a first sensor 11 is disposed inside the housing 14 of the sensing device 100. The sensing device 100 detects abnormal states of the gas stove 200 through the first sensor 11, such as... Figure 5 and Figure 6As shown, the front side of the housing 14 of the sensing device 100 has a first opening 141. The first sensor 11 detects abnormal states of the gas stove 200 through the first opening 141. The first sensor 11 can obtain light or odor through the first opening 141, thereby realizing the detection of abnormal states of the gas stove 200. The first opening 141 serves as a monitoring window. In one embodiment, a light-transmitting sheet 143 is provided on the first opening 141, which protects the first sensor 11. Preferably, the first opening 141 is not higher than the height of the pot rack 23 of the gas stove 200, so as to ensure that the first sensor 11 can detect the area of ​​the burner 22 and the pot rack 23 without being blocked by the cooking utensils on the pot rack 23.

[0089] The housing 14 of the sensing device 100 also includes a circuit board 12. The first sensor 11 is disposed on the circuit board 12. The circuit board 12 is arranged vertically within the housing 14 of the sensing device 100, which helps to reduce the space occupied by the sensing device 100 in the lateral direction, making it easier to arrange the sensing device 100 on the gas stove 200 and facilitating the adaptation between the two. Figure 6 As shown, the first sensor 11 is disposed on the front side of the circuit board 12, and the rear side of the circuit board 12 is connected to the first communication module 101.

[0090] The housing 14 of the sensing device 100 also includes a battery 13. The battery 13 is located near the rear side of the housing 14 and behind the circuit board 12, making the space inside the housing 14 of the sensing device 100 more compact. This also facilitates the side-by-side installation of the battery 13 and circuit board 12 into the housing, reducing the overall size of the sensing device 100 and minimizing its interference with the user's cooking operations. Preferably, both the circuit board 12 and the battery 13 are... Figure 6 The two flat plates shown are roughly parallel, which minimizes the space they occupy.

[0091] In one embodiment, the housing 14 of the sensing device 100 includes a removable cover 161 and a base plate 162, such as Figure 7 As shown, a second opening 142 is provided at the bottom of the cover 161, and the base plate 162 is detachably connected to the cover 161 through the second opening 142. Furthermore, a clamping member 17 is provided on the base plate 162. The clamping member 17 extends into the cover 161 through the second opening 142 and clamps the circuit board 12 and / or the battery 13. The clamping member 17 applies a pushing force to the circuit board 12 and the battery 13, causing the circuit board 12 and the battery 13 to abut against the inner wall of the cover 161, improving the stability of the internal structure of the sensing device 100. Furthermore, the clamping member 17 is inserted through the second opening 142 at the bottom of the cover 161, making assembly more convenient and reducing the manufacturing difficulty of the sensing device 100.

[0092] The clamping member 17 can be a pressure plate 171. The pressure plate 171 extends upward into the cover 161 through the second opening 142 and is located behind the circuit board 12. The pressure plate 171 applies a forward pushing force to the circuit board 12. After the pressure plate 171 is fully inserted, the base plate 162 is fixed to the bottom of the cover 161 by locking screws, thereby locking the positions of the base plate 162, the pressure plate 171, and the circuit board 12. Figure 7 As shown, the pressure plate 171 is located between the battery 13 and the circuit board 12, and also serves to separate the battery 13 from the circuit board 12. Furthermore, the front side of the pressure plate 171 is provided with a slope 172, so that when the pressure plate 171 extends upward through the second opening 142, the slope 172 applies a forward pushing force to the circuit board 12, which facilitates the assembly of the circuit board 12 and the housing 14.

[0093] In another embodiment, the pressure plate 171 extends upward into the cover 161 through the second opening 142 and extends between the battery 13 and the circuit board 12. The pressure plate 171 can simultaneously apply a forward pushing force to the circuit board 12 and a backward pushing force to the battery 13. The base plate 162 is fixed to the bottom of the cover 161 by locking screws, thereby locking the positions of the base plate 162, the pressure plate 171, the circuit board 12 and the battery 13.

[0094] like Figure 5 As shown, the cross-sectional area of ​​the lower part of the cover 161 is larger than that of the upper part of the cover 161, so that the sensing device 100 has a shape that is smaller at the top and larger at the bottom, which improves stability and makes it easier to place the sensing device 100 on the stove 24, thus preventing the sensing device 100 from tipping over.

[0095] Furthermore, the cover 161 includes an upper cover 151 and a lower cylinder 154, such as Figure 6 As shown, a first opening 141 is provided on the front side of the upper cover 151, and a groove 155 is provided on the front side wall of the lower cylinder 154. The upper cover 151 is provided with a protrusion 152 that mates with the groove 155. The protrusion 152 is inserted into the groove 155 to connect the upper cover 151 and the lower cylinder 154 together. Preferably, a positioning post 153 is provided on the inner wall of the protrusion 152, and a positioning hole is provided on the circuit board 12. The positioning post 153 is inserted into the positioning hole to position the circuit board 12 and the first sensor 11.

[0096] The abnormal conditions detected by the sensing device 100 include one or more of the following: dry burning, overflow, flameout, and gas leakage. For example, when dry burning occurs, the cookware and food will emit a burnt smell, which the sensing device 100 can detect through a gas sensor; when overflow occurs, the overflowing liquid will emit a special smell due to high temperature, and the gas stove 200 may be extinguished, so the sensing device 100 can detect this through a gas sensor or a light sensor, or through a combination of a light sensor and a gas sensor; when flameout occurs, the sensing device 100 can detect this through a light sensor; when a gas leak occurs, the sensing device 100 can detect this through a gas sensor.

[0097] In some embodiments, the first sensor 11 includes a light sensor for detecting the flame state of the gas stove 200 and / or a gas sensor for detecting the gas concentration. Abnormal states of the gas stove 200 detected by the light sensor and / or gas sensor are used to control the switching device 21. By determining abnormal states through flame state and / or gas concentration, the sensing device 100 may contain only one or more light sensors, or only one or more gas sensors, or both light and gas sensors. The light sensor may include an infrared sensor, specifically a dual-channel infrared sensor, etc. Depending on the characteristics of the abnormal state, the sensing device 100 may be equipped with corresponding sensors for detection.

[0098] When an abnormal state such as dry burning, flameout, or gas leakage occurs, the sensor 100 communicates directly or indirectly with the gas stove controller 201, and the gas stove controller 201 controls the switch device 21 to cut off the gas supply. When an abnormal state of overflow occurs, the sensor 100 communicates directly or indirectly with the gas stove controller 201, and the gas stove controller 201 controls the switch device 21 to reduce the gas supply. If the overflow continues after reducing the gas supply for a period of time, the gas stove controller 201 controls the switch device 21 to cut off the gas supply.

[0099] In some embodiments, the sensing device 100 is disposed on the gas stove 200. The sensing device 100 and the gas stove 200 body can be connected by a mechanical structure. Integrating the sensing device 100 into the gas stove 200 helps to further ensure the accuracy of the position of the sensing device 100 on the gas stove 200 and the reliability of the detection.

[0100] To facilitate the placement of the sensing device 100 on the gas stove 200, the inventors made an optimized design: the sensing device 100 is the knob of the gas stove 200, and the knob of the burner 22 is the switch 26 that controls the operation of the burner, used to control the working state of the gas stove 200. That is, the first sensor 11 of the sensing device 100 is integrated into the knob of the gas stove 200, and the sensing device 100 and the knob of the gas stove 200 are a single structure, thereby avoiding the sensing device 100 occupying additional space above the gas stove 200 and making it easier for the user to operate.

[0101] In another embodiment, the gas stove 200 is equipped with a lifting mechanism, and the sensing device 100 is installed on the lifting mechanism. The lifting mechanism can move the sensing device 100 to adjust its position, which is beneficial for moving the sensing device 100 to a suitable position for detection, while reducing interference to the user. Preferably, the lifting mechanism can move the sensing device 100 to the aforementioned position and height for detection.

[0102] Furthermore, driven by the lifting mechanism, the sensing device 100 has a first position at least partially embedded in the surface of the gas stove 200 and a second position at least partially protruding from the surface of the gas stove 200. During cooking, the lifting mechanism moves the sensing device 100 to the second position to detect the gas stove 200; when not in use, the lifting mechanism moves the sensing device 100 to the first position to reduce the space occupied by the sensing device 100 above the gas stove 200, which helps to keep the upper surface of the gas stove 200 clean.

[0103] Furthermore, the stove 24 is provided with a third opening, and a lifting mechanism is provided in the third opening. The lifting mechanism can drive the sensor 100 to extend through the third opening or embed into the surface of the gas stove 200. Preferably, the third opening is provided with a movable door. After the movable door is opened, the lifting mechanism can drive the sensor 100 to extend through the third opening to a second position. After the lifting mechanism drives the sensor 100 to descend to the first position, the movable door can automatically close to seal the third opening, so that the surface of the stove 24 remains flat.

[0104] Option 2

[0105] This invention provides a range hood and cooktop system, such as Figure 8As shown, the range hood and stove system includes a range hood 300 and the aforementioned stove system. The stove system's sensing device 100 is equipped with a first communication module 101, and the stove system's gas stove controller 201 includes a second communication module 202. The stove system's sensing device 100 is used to communicate directly or indirectly with the range hood controller 301 through the first communication module 101 based on the detected abnormal state of the gas stove 200, and then directly or indirectly with the range hood controller 301 through the second communication module 202, so that the gas stove controller 201 controls the switch device 21 to operate.

[0106] The sensing device 100 detects the status of the gas stove 200. When an abnormal state occurs, the signal from the sensing device 100 is transmitted directly or indirectly to the range hood controller 301 through the first communication module 101. The range hood controller 301 then transmits the signal directly or indirectly to the second communication module 202. The gas stove controller 201 controls the switch device 21 to operate according to the received signal. The switch device 21 operates to cut off or reduce the gas intake, thereby stopping the flame or reducing the flame, thus achieving automated control of the working status of the gas stove 200, preventing the abnormal state from worsening, ensuring the safety of the cooking process, promoting the automation and intelligence of cooking, and improving cooking efficiency.

[0107] Furthermore, the range hood controller 301 includes a third communication module 303 and a fourth communication module 304, such as... Figure 10 As shown, the third communication module 303 is used to communicate with the first communication module 101, and the fourth communication module 304 is used to communicate with the second communication module 202. The signal of the sensing device 100 is transmitted directly or indirectly to the third communication module 303 through the first communication module 101. The range hood controller 301 then transmits the signal directly or indirectly to the second communication module 202 through the fourth communication module 304, thereby transmitting the signal of the sensing device 100 to the gas stove controller 201.

[0108] The third communication module 303 can communicate directly with the first communication module 101, meaning the first communication module 101 can directly transmit signals to the third communication module 303 via wired or wireless means. The third communication module 303 and the first communication module 101 can also communicate indirectly. For example, the range hood system also includes a central control device 400; the first communication module 101 first transmits signals to the central control device 400, and the central control device 400 then transmits the signals to the third communication module 303.

[0109] The fourth communication module 304 can communicate directly with the second communication module 202, meaning the fourth communication module 304 can directly transmit signals to the second communication module 202 via wired or wireless means. The fourth communication module 304 and the second communication module 202 can also communicate indirectly. For example, in a system that also includes a central control device 400, the fourth communication module 304 first transmits signals to the central control device 400, and then the central control device 400 transmits the signals to the second communication module 202.

[0110] The central control device 400 can be a smart terminal or a central control system for the kitchen. The first communication module 101, the second communication module 202, the third communication module 303, and the fourth communication module 304 can be WIFI modules, Bluetooth modules, network communication modules, or wired communication modules. The signals transmitted between the first communication module 101, the second communication module 202, the third communication module 303, and the fourth communication module 304 can be the raw signals detected by the sensing device 100 or the processed switching signals, including control commands such as turning off the switch device 21 or adjusting the switch device 21.

[0111] In one embodiment, the sensing device 100 is also used to detect the on / off state of the gas stove 200, and the range hood controller 301 is used to control the on / off state of the range hood 300 based on the on / off state of the gas stove 200. After the sensing device 100 detects that the gas stove 200 is turned on, the signal of the sensing device 100 is transmitted to the range hood controller 301 through the first communication module 101, and the range hood controller 301 controls it to start exhausting air. After the sensing device 100 detects that the gas stove 200 is turned off, the signal of the sensing device 100 is transmitted to the range hood controller 301 through the first communication module 101, and the range hood controller 301 controls it to turn off, realizing the linkage between the range hood 300 and the gas stove 200, and improving the exhaust effect of the range hood 300.

[0112] There are many ways for the sensing device 100 to detect the on / off status of the gas stove 200. For example, the sensing device 100 may be a knob of the gas stove 200, which rotates to control the on / off status of the gas stove 200, and the sensing device 100 obtains the on / off status of the gas stove 200 by the rotation angle of the knob; or, the sensing device 100 may include a light sensor, which detects whether the gas stove 200 is in a combustion state to determine the on / off status of the gas stove 200; or, the sensing device 100 may communicate with the controller 201 of the gas stove to obtain the on / off status of the gas stove 200.

[0113] In one embodiment, the sensing device 100 is also used to detect the flame status of the gas stove 200, and the range hood controller 301 is used to control the range hood 300's setting based on the flame status of the gas stove 200. When the gas stove 200 is burning at a strong flame, the range hood 300's setting is increased; when the gas stove 200 is burning at a weak flame, the range hood 300's setting is decreased, so that the airflow follows the flame, further improving the ventilation effect. The sensing device 100 can detect the flame status of the gas stove 200 in a similar way to detecting the on / off state of the gas stove 200, which will not be described in detail here.

[0114] In one embodiment, the range hood system further includes a gas sensor 302 located above the cooktop system. The range hood controller 301 communicates directly or indirectly with the cooktop controller 201 based on data detected by the gas sensor 302, enabling the cooktop controller 201 to control the state of the switching device 21. When flameout or gas leakage occurs, the gas sensor 302 detects gas, and in this case, the cooktop controller 201 controls the switching device 21 to cut off the gas supply. When overflow or dry burning occurs, food produces a distinctive odor due to overheating, and the gas sensor 302 detects this odor; in this case, the cooktop controller 201 controls the switching device 21 to cut off the gas supply. The gas sensor 302's location above the cooktop system, where gas typically flows upwards, facilitates gas sensor 302 detection, improving the reliability and accuracy of safety monitoring.

[0115] The range hood controller 301 and the gas stove controller 201 can communicate directly; the range hood controller 301 and the gas stove controller 201 can also communicate indirectly, for example, as... Figure 11 As shown, the range hood controller 301 and the gas stove controller 201 communicate through the central control device 400 or the sensing device 100.

[0116] In one embodiment, the gas sensor 302 includes at least a methane sensor. When the methane sensor detects excessive methane levels, it locks the control panel of the range hood 300. Excessive methane concentration can easily cause an explosion if exposed to a spark. Operating the control panel of the range hood 300 may generate sparks when electrical components are activated. By locking the control panel, the user cannot turn the range hood 300 on and / or off, or simply cannot turn it on, thus preventing the electrical components from starting and stopping, avoiding sparks, and ensuring safety.

[0117] Furthermore, the gas sensor 302 includes at least a methane sensor. When the methane sensor detects excessive methane levels and the range hood 300 is not in operation, the control panel of the range hood 300 is locked. Considering that users typically turn on the range hood 300 to ventilate when odors are present but it is not in operation, locking the control panel of the range hood 300 prevents electrical components from starting and stopping when methane levels are excessive, thereby avoiding sparks and better ensuring safety.

[0118] The above descriptions are merely a few embodiments of the present invention. Those skilled in the art can make various modifications or variations to the embodiments of the present invention based on the content disclosed in the application documents without departing from the spirit and scope of the present invention.
