[0058] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0059] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0061] In the description of the embodiments of the present disclosure, the terms "upper", "lower", "left", "right", etc., and the like, are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0062] Embodiment 1

[0063] like Figure 1 As shown, the embodiment of the present disclosure discloses a smoke stove linkage control device 100, which includes a stove 10 and a range hood 40, wherein the stove 10 can cook food, and the range hood 40 is arranged above the stove 10, and the range hood 40 can discharge oil smoke during the cooking process.

[0064] Specifically, if Figure 1 As shown, the stove 10 includes a stove panel 14, a burner 11 and a pot rack 17, wherein the burner 11 and the pot rack 17 are arranged on the stove panel 14, the burner 11 can emit flames, the emitted flames can cook food, and the pot rack 17 can support the pot (not shown in the figure). Figure 1 As shown, the range hood 40 includes a range hood housing 41 and a fan (not shown in the figure). The range hood housing 41 has a smoke inlet 411. When the fan is working, the smoke sucked from the smoke inlet 411 is purified by the centrifugal filtration of the fan, and the purified smoke is discharged from the air outlet of the range hood housing 41. Figure 1 As shown, the range hood 40 further includes a smoke collecting plate 42, which is disposed at the smoke inlet 411. The arrangement of the smoke collecting plate 42 can achieve better introduction of smoke into the smoke inlet 411, and the arrangement of the smoke collecting plate 42 can achieve a better absorption effect of the smoke by the range hood 40. Figure 1 As shown, the range hood 40 also includes a check valve 43, which is arranged at the air outlet. The setting of the check valve 43 can prevent the oil smoke in the public flue from flowing back into the kitchen, and can also prevent insects such as mosquitoes and flies from entering the room and affecting the kitchen environment.

[0065] Since the flame emitted by the burner 11 is blocked by the cookware, it is not convenient for the user to observe the size of the flame. The user needs to bend over to observe the flame, which is not conducive to the user's cooking operation.

[0066] To solve the above problems, Figure 1As shown, the smoke and stove linkage control device 100 also includes a detection mechanism 20 and a display mechanism 30. The detection mechanism 20 is used to detect the intensity of the flame light of the burner 11. The display mechanism 30 is communicatively connected to the detection mechanism 20. The display mechanism 30 is used to display the corresponding intensity information 200 of the flame light of the burner 11. By observing the corresponding intensity information 200, the user can quickly and clearly perceive the current flame size, avoiding the need for the user to bend down to observe the flame of the burner 11, thereby facilitating the user's cooking operations.

[0067] Exemplarily, the detection mechanism 20 may be a photodiode sensor, which refers to a sensor that detects light signals through the photoelectric effect, and has the advantages of fast response speed, high sensitivity, and easy manufacturing. The working principle of the photodiode sensor is: when a light beam is irradiated onto a photodiode, a photoelectron flow is stimulated to form a current, the magnitude of which is proportional to the light intensity, and the magnitude of the light intensity can be determined by detecting the magnitude of the current.

[0068] In an optional embodiment, the detection mechanism 20 can also be a photoresistor sensor, which refers to a sensor that detects light signals by using the resistance change caused by light. The photoresistor sensor has the advantages of low cost and ease of use. The working principle of the photoresistor sensor is that when light irradiates the photoresistor, the resistance changes, and the resistance value is inversely proportional to the light intensity. By detecting the resistance size, the light intensity can be determined.

[0069] In an optional embodiment, the detection mechanism 20 can also be a fiber optic sensor, which refers to a sensor that uses optical fiber to transmit optical signals to detect physical quantities. The fiber optic sensor has the advantages of anti-electromagnetic interference and high reliability. The working principle of the fiber optic sensor is: by transmitting the optical signal to the measuring end through the optical fiber, and then converting the optical signal into an electrical signal for detection. The fiber optic sensor can select different types of optical fibers according to different requirements, such as multi-mode optical fiber, single-mode optical fiber, fiber grating, etc.

[0070] In an optional embodiment, the communication connection between the display mechanism 30 and the detection mechanism 20 can be a wire connection, an infrared connection, a Bluetooth connection, a digital data communication (e.g., a communication network) connection in any form or medium, etc. Examples of communication networks include a local area network (LAN), a wide area network (WAN), a blockchain network, the Internet, etc.

[0071] Regarding the communication connection between the display mechanism 30 and the detection mechanism 20, as shown in FIG. Figure 2 As shown, the cooker 10 further includes a first controller 16, and the range hood 40 further includes a second controller 44. Specifically, in order to illustrate the electrical connection principle of each electrical component, as shown in FIG. Figure 2As shown, the detection mechanism 20, the first controller 16, the second controller 44 and the display mechanism 30 are sequentially connected in communication, and the intensity signal of the flame light of the burner 11 detected by the detection mechanism 20 is transmitted to the first controller 16, and the first controller 16 transmits the signal required to be output by the display mechanism 30 to the display mechanism 30 through the second controller 44, thereby realizing the control of the intensity information 200 output by the display mechanism 30. Among them, the first controller 16 or the second controller 44 can be a centralized or distributed controller, for example, the first controller 16 or the second controller 44 can be a single chip microcomputer, or can be composed of multiple distributed single chip microcomputers, and the control program can be run in the single chip microcomputer.

[0072] In an optional embodiment, if Figure 1 As shown, the display mechanism 30 is a projection mechanism, which is arranged on the range hood 40. The projection mechanism can project the corresponding intensity information 200 onto the cooker 10 or the wall 300. The intensity information 200 is a projection of the projection mechanism, which is convenient for users to timely view the intensity information 200. By adjusting the position of the projection mechanism, the projection mechanism can project the intensity information 200 to a suitable position, which is convenient for users to view and matches different usage scenarios of users.

[0073] In an optional embodiment, the display mechanism 30 can be detachably connected to the range hood 40, the stove 10 and the wall 300, and the position of the intensity information 200 can be adjusted by adjusting the installation position of the display mechanism 30. Exemplarily, the display mechanism 30 can be connected to the range hood 40, the stove 10 and the wall 300 by screws, pins, snap-on components, magnetic components, etc. It should be noted that this optional embodiment only lists some of the implementation methods, and all structures that can realize the detachable connection of the display mechanism 30 with the range hood 40, the stove 10 and the wall 300 are within the protection scope of this optional embodiment.

[0074] In an optional embodiment, the angle between the display mechanism 30 and the part to be installed (which may be the range hood 40, the stove 10 or the wall 300, etc.) is adjustable, thereby further realizing the adjustment of the position of the intensity information 200. For example, the display mechanism 30 and the range hood 40 (or the stove 10, or the wall 300) may be pivotally connected, and the display mechanism 30 and the part to be installed may also be locked by a locking mechanism, thereby maintaining the relative position between the display mechanism 30 and the part to be installed. The locking mechanism may be a screw, a pin, a buckle assembly, a magnetic suction assembly, etc.

[0075] In an optional embodiment, the relative position between the display mechanism 30 and the part to be installed is adjustable, thereby further realizing the adjustment of the position of the strength information 200. In addition, the display mechanism 30 and the part to be installed can be locked by a locking mechanism, thereby maintaining the relative position between the display mechanism 30 and the part to be installed. The locking mechanism can be a screw, a pin, a buckle assembly, a magnetic suction assembly, etc.

It should be noted that the intensity information 200 may also include one area, two areas, four areas, or more areas, etc., according to the different levels of the intensity of the flame light of the burner 11, and corresponding areas may be set for each level. The more areas are set, the more levels of the intensity of the flame light of the burner 11.

[0077] In an optional embodiment, Figure 6 to Figure 8 As shown, the intensity information 200 is an image projected by the projection mechanism, and the intensity information 200 includes an image with variable brightness, such as Figure 6 As shown, when the detection mechanism 20 detects that the burner 11 has no flame light, the intensity information 200 is a non-luminous image; Figure 7 As shown, when the detection mechanism 20 detects that the brightness of the flame light of the burner 11 is low, the intensity information 200 is an image with low brightness; Figure 8 As shown, when the detection mechanism 20 detects that the brightness of the flame light of the burner 11 is relatively high, the intensity information 200 is an image with relatively high brightness.

[0078] In an optional embodiment, if Fig. 9 and Fig.10 As shown, the display mechanism 30 may be a display screen, and the intensity information 200 may be an electronic pattern displayed on the display screen. The change of the electronic pattern may also realize the adaptive display of different degrees of intensity of the flame light of the burner 11. Fig. 9 and Fig.10As shown, the display mechanism 30 is provided with a first area 210, a second area 220, a third area 230 and a fourth area 240. Fig. 9 As shown, when the detection mechanism 20 detects that there is no flame light in the burner 11, the first area 210, the second area 220, the third area 230 and the fourth area 240 are all dark; Fig. 9 As shown, when the detection mechanism 20 detects that the flame of the burner 11 is at a first brightness level, only the first area 210 emits light; Fig. 9 As shown, when the detection mechanism 20 detects the second brightness of the flame of the burner 11, only the first area 210 and the second area 220 emit light; Fig.10 As shown, when the detection mechanism 20 detects the flame brightness of the burner 11 at three levels, the first area 210, the second area 220 and the third area 230 emit light; Fig.10 As shown, when the detection mechanism 20 detects the flame brightness of the burner 11, the first area 210, the second area 220, the third area 230 and the fourth area 240 all emit light. The brightness of the flame corresponding to the first flame brightness, the second flame brightness, the third flame brightness and the fourth flame brightness increases in sequence.

[0079] In an optional embodiment, if Figure 11 to Figure 13 As shown, the corresponding intensity information 200 includes variable numbers, which can make people more intuitively perceive the intensity of the flame light. Fig.11 As shown, when the detection mechanism 20 detects that the flame of the burner 11 is at a brightness level, the number "1" lights up; Fig.12 As shown, when the detection mechanism 20 detects the second brightness of the flame of the burner 11, the number "2" lights up; Fig.13 As shown, when the detection mechanism 20 detects the third level of flame brightness of the burner 11, the number "3" lights up; wherein the brightness of the flames corresponding to the first level of flame brightness, the second level of flame brightness and the third level of flame brightness increase in sequence.

[0080] In an optional embodiment, if Figure 11 to Figure 13 As shown, the corresponding intensity information 200 includes variable numbers, which can make people more intuitively perceive the intensity of the flame light. Fig.11 As shown, when the detection mechanism 20 detects that the flame of the burner 11 is at a brightness level, the number "1" lights up; Fig.12 As shown, when the detection mechanism 20 detects the second brightness of the flame of the burner 11, the number "2" lights up; Fig.13 As shown, when the detection mechanism 20 detects the third level of flame brightness of the burner 11, the number "3" lights up; wherein the brightness of the flames corresponding to the first level of flame brightness, the second level of flame brightness and the third level of flame brightness increase in sequence.

[0081] In an optional embodiment, Figure 11 to Figure 13 Compared to the display shown in Figure 14 to Figure 16 The display area shown is smaller, e.g. Figure 14 to Figure 16 The image displayed on the display screen shown can be switched between different numbers.

The valve shaft 121 is penetrated in the through hole 213 and fixed to the knob 13. When the knob 13 rotates, it will not drive the detection mechanism 20 to follow. The detection mechanism 20 is set without making major changes to the stove 10, and the existing stove 10 that has been produced can be simply changed to achieve the modification of the new stove 10. In addition, the arrangement between the detection mechanism 20, the valve shaft 121 and the knob 13 is compact, which can realize the effective arrangement of the detection mechanism 20 in a small space, and the overall appearance of the stove 10 is more beautiful.

[0085] In an optional embodiment, if Figure 1 , Figures 17 to 20As shown, the detection mechanism 20 is detachably connected to the stove 10, which facilitates the rapid disassembly and assembly of the detection mechanism 20 and the stove 10, and facilitates the rapid replacement of the detection mechanism 20.

In addition, the connecting portion 2122 and the stove panel 14 can be connected by threads, so that the user can quickly disassemble and assemble the detection mechanism 20 and the stove panel 14 in a small space. In an optional embodiment, the connecting portion 2122 and the stove panel 14 can be detachably connected by screw connection, pin connection, bayonet assembly, magnetic assembly, etc. All structures that can realize the detachable connection between the connecting portion 2122 and the stove panel 14 are within the protection scope of the disclosed embodiment.

On the one hand, the detection mechanism 20 is protected by the knob 13, and the detection mechanism 20 is away from the burner 11, so as to avoid the detection mechanism 20 from being polluted or damaged. On the other hand, the arrangement of the detection mechanism 20 will not affect the specific structure of the burner 11, and can ensure that the bottom of the pot is heated evenly, and the inner ring flame will not affect the detection accuracy of the detection mechanism 20, so that the detection mechanism 20 can achieve a higher detection accuracy. Specifically, the light-transmitting material can be glass, plastic, rubber, etc.

[0095] Specifically, if Fig.18 and Fig.19 As shown, the knob 13 includes a top plate 131 and a side wall 132. The top plate 131 is located above the detection mechanism 20 and is fixedly connected to the valve shaft 121. The side wall 132 is formed by extending downward from the outer periphery of the top plate 131. The side wall 132 is arranged around the outer periphery of the detection mechanism 20. The structure is simple and easy to manufacture.

The cross section of the plug hole 13121 is non-circular, and the size and shape of the cross section of the valve shaft 121 are the same as the size and shape of the plug hole 13121. By setting it in a non-circular shape, the connecting column 1312 and the valve shaft 121 can be prevented from rotating relative to each other. Exemplarily, the cross section of the plug hole 13121 can be "D"-shaped, special-shaped, etc. All various shapes of the cross section of the plug hole 13121 that can prevent the connecting column 1312 and the valve shaft 121 from rotating relative to each other are within the protection scope of the embodiments of the present disclosure.

[0097] In an optional embodiment, if Figure 2 As shown, the detection mechanism 20 is connected to the fan 45 for communication, and the fan 45 can adjust the air volume of the fan 45 according to the intensity of the flame light detected by the detection mechanism 20, thereby realizing the linkage between the range hood 40 and the stove 10, and realizing the automatic adaptive adjustment of the air volume of the fan 45 according to the intensity of the flame light, freeing the hands of the user and facilitating the cooking operation. Figure 2 As shown, the second controller 44 is communicatively connected with the fan 45. The communication connection may be a wire connection, an infrared connection, a Bluetooth connection, a digital data communication (e.g., a communication network) connection in any form or medium, etc. Examples of communication networks include a local area network (LAN), a wide area network (WAN), a blockchain network, the Internet, etc.

[0098] In an optional embodiment, if Figure 2 As shown, the smoke and stove linkage control device 100 also includes an alarm device 60, which is communicatively connected to the detection mechanism 20. Specifically, the alarm device 60 is communicatively connected to the first controller 16. If the intensity of the flame light of the burner 11 does not change within a first preset time period, the first controller 16 starts timing. If the timing duration exceeds a second preset time period, the alarm device 60 is controlled to alarm, which can remind the user and avoid problems such as dry burning of pots or kitchen fire accidents caused by the user not being near the stove 10.

[0099] If the time duration does not exceed the third preset time duration, and the third preset time duration is greater than the second preset time duration, it means that the user has operated the knob 13 again, and the aforementioned risk hidden danger is eliminated, then the timing step stops and the alarm device 60 is turned off. Specifically, in this step, the detection mechanism 20 can detect whether the intensity of the flame light changes.

[0100] If the timing duration exceeds the third preset duration, it means that the user fails to operate the knob 13 in time and the aforementioned risk hidden danger cannot be eliminated. The first controller 16 controls the burner 11 to turn off the fire and controls the alarm device 60 to stop the alarm, and the stove 10 automatically turns off the fire to avoid the occurrence of the aforementioned problem.

The range hood 40 is powered by AC power, and there is no need to worry about the detection mechanism 20 being installed on the stove 10 and consuming battery power.

[0103] like Figure 2 and Fig. 22 As shown, the cooker 10 further includes a position detection device 18, which is electrically connected to the first controller 16 and is used to detect the state of the knob 13. The setting of the position detection device 18 can timely determine whether the intensity of the flame light of the burner 11 changes from the change in the physical state of the knob 13. Exemplarily, the position detection device 18 can be a potentiometer or a Hall sensor installed on the valve shaft 121, and all mechanisms that can realize the state detection of the knob 13 are within the protection scope of the embodiments of the present disclosure.
