In certain embodiments, the first temperature sensor 22 may be a dry-fire proof temperature probe disposed in a burner of the cooktop. The temperature of the pot 30 is obtained by a dry-heating prevention temperature probe of the pot 20. The dry-heating preventing temperature probe is used for detecting the temperature of the pot 30.

It should be noted that, in the smoke and range linkage control process according to the embodiment of the present invention, the wind power of the fan controlling the range hood 10 is actually not necessarily related to whether the pan 30 is placed on the range 20, and the collected temperature of the pan 30 can be understood as the temperature data output by the temperature sensor (such as the dry-burning prevention temperature probe), and is not necessarily related to whether the pan 30 is placed on the range 20. In the example of fig. 2, when the pot 30 is placed on the cooker 20, the pot 30 is elastically abutted with the dry-heating prevention temperature probe so that the dry-heating prevention temperature probe acquires a more accurate temperature of the pot.

In some embodiments, the temperature of the pot 30 is detected by a temperature sensor disposed at the pot 30. Referring to fig. 8, in one embodiment, the pot 30 is an intelligent pot, and includes a second temperature sensor 32, a second temperature signal processing unit 34 and a second temperature signal transmitting unit 36.

The range hood 10 includes a second detection signal receiving unit 11 and a second wind power adjusting unit 13. The control device 50 is disposed on the range hood 10. The second temperature sensor 32 of the pot feeds back the temperature signal to the second temperature signal processing unit 34, and the second temperature signal processing unit 34 transmits the processed temperature signal to the second temperature signal transmitting unit 36. The second fire signal detection unit 23 feeds back the fire signal to the second fire signal processing unit 25. The first fire signal processing unit 28 transfers the fire signal to the second fire signal transmitting unit 27. The second temperature signal transmitting unit 36 then transmits the temperature signal to the second detection signal receiving unit 11 by wire or wirelessly, and the second fire signal transmitting unit 27 then transmits the fire signal to the second detection signal receiving unit 11 by wire or wirelessly. The second detection signal receiving unit 11 feeds back the temperature signal and the fire signal to the control device 50, and the control device 50 determines the temperature of the pot 30 through calculation and determines the cooking state of the cooker 20 according to the temperature of the pot 30. Then, the operating state adjusting strategy of the range hood 10 is determined according to the cooking state and the temperature of the cooker 30 and a control signal is generated. The control device 50 sends an operation command of a control signal to the second wind power adjustment unit 13 of the range hood 10, so that the range hood 10 automatically adjusts the wind power of the fan of the range hood 10 according to the operation command. The second temperature sensor 32 can be arranged in the interlayer of the bottom of the pot body of the pot, and the second temperature signal processing unit 34 and the second temperature signal transmitting unit 36 can be arranged on the handle of the pot 30, and the handle is connected with the side edge of the pot body.

In another embodiment, referring to fig. 9, the cigarette making machine 10 further includes an illumination device 16, and the control device 50 sends an action command of a control signal to the second wind power adjustment unit 13 and the illumination device 16 of the cigarette making machine 10, so that the cigarette making machine 10 automatically adjusts the wind power of the fan of the cigarette making machine 10 and controls the operating state of the illumination device 16 according to the action command.

In another embodiment, referring to fig. 10, the temperature of the pot 30 is detected by a temperature sensor 31 disposed at the pot 30. The temperature sensor 31 may be a wireless passive temperature sensor. The wireless passive temperature sensor does not need power supply, and can send out the collected temperature data in a wireless mode, and the second detection signal receiving unit 11 can receive the temperature data transmitted by the wireless passive temperature sensor 31. The temperature sensor 31 may be provided at the bottom of the pot 30.

In yet another embodiment, referring to fig. 11, the temperature of the pot 30 is detected by a wireless passive temperature sensor 31 disposed in the pot 30. The range hood 10 further comprises an illumination device 16, and the control device 50 sends an action command of a control signal to the second wind power adjusting unit 13 and the illumination device 16 of the range hood 10, so that the range hood 10 automatically adjusts the wind power of a fan of the range hood 10 according to the action command and controls the working state of the illumination device 16.

It is understood that the cooking state of the cooktop 20 may be a water cooking state or a no water cooking state. The cooking with water can be in a water cooking mode such as stewing, boiling, stewing, steaming and the like. The waterless cooking comprises frying, stir-frying, frying and other waterless cooking modes. When the cooking utensil 20 is in a water cooking state, the inventor finds that the temperature-time curves 1 and 2 of the pot 30 have a typical three-segment distribution characteristic, the curve 1 is a temperature curve of the pot with better heat conductivity and the time, and the curve 2 is a temperature curve of the pot with poorer heat conductivity and the time, as shown in fig. 12: a first stage: when the cooker 20 starts to heat, the temperature of the pot 30 gradually rises; and a second stage: when the water in the pot is boiling, the temperature of the pot 30 is in a constant or approximately constant state, that is, a boiling section exists at the moment; a third stage: when the water in the pot is dried, the temperature of the pot 30 rises again. Wherein, the pan boiling temperature of curve 1 and curve 2 is inequality, generally, the size of pan boiling temperature is relevant with the heat conductivity of pan 30, and is better if the heat conductivity of pan 30, and the pan boiling temperature is less. When the cooking utensil 20 is in the water-free cooking state, the temperature curve 3 of the temperature of the pot 30 and the time fluctuates greatly and has no obvious law, as shown in fig. 13.

Referring to fig. 14, in some embodiments, the cooking states of the cooktop include a water cooking state and a no water cooking state, and step S30 includes:

s31, judging whether the cooking range 20 is in a water cooking state or a water-free cooking state;

s32, when the cooking stove is in a water cooking state, controlling a fan of the range hood 10 to operate by preset wind power; and

and S34, when the cooker is in a water-free cooking state, controlling the fan of the range hood 10 to operate by wind power positively correlated with the current temperature of the cooker 30.

The control method of the present embodiment may be implemented by the smoke and fire linkage system 100 of the present embodiment, wherein steps S31, S32, and S34 of the smoke and fire linkage control method of the present embodiment may be implemented by the control device 50. That is, the control device 50 is used for judging whether the cooking range 20 is in a water cooking state or a water-free cooking state, and when the cooking range 30 is in the water cooking state, controlling the fan of the range hood 10 to operate by preset wind power; and when the cooking utensil 20 is in a water-free cooking state, controlling the fan of the range hood 10 to operate by wind power positively correlated with the current temperature of the cooking utensil 30.

Therefore, the wind power of the fan of the range hood 10 is controlled according to the cooking state of the cooker 20, so that the wind power of the fan can be accurately controlled to enable the range hood to meet the oil smoke absorption requirement during cooking, and the user experience is good.

Specifically, when the cooking range 20 is in a water cooking state, the fan of the range hood 10 may be controlled to operate by a preset wind power, which may be understood as controlling the fan of the range hood 10 to operate by a preset gear to realize that the fan outputs the preset wind power in one embodiment, and controlling the fan of the range hood 10 to operate by a preset rotation speed or operate according to a preset rotation speed relationship curve to realize that the fan outputs the preset wind power in another embodiment.

When the cooker is in a water-free cooking state, the fan of the range hood 10 can be controlled to operate with wind power positively correlated to the current temperature of the cooker 30. For example, the higher the current temperature of the pot 30, the greater the wind force of the fan. It should be noted that the positive correlation between the wind power of the fan and the current temperature of the pot 30 includes the following cases: different wind forces of the fan may correspond to different temperature ranges of the pot 30. For example, the wind power includes three different wind powers of F1, F2 and F3, wherein the temperature range of the pan 30 corresponding to F1< F2< F3, F1 is [ T11, T12], the temperature range of the pan 30 corresponding to F2 is (T12, T13], the temperature range of the pan 30 corresponding to F3 is (T13, T14], when the current temperature of the pan 30 is in the range of [ T11, T12], the fan is controlled to operate at F1, when the current temperature of the pan 30 is in the range of (T12, T13], the fan is controlled to operate at F2, when the current temperature of the pan 30 is in the range of (T13, T14], the fan is controlled to operate at F3, and the wind power of the fan can be adjusted by the rotation speed and/or gear of the fan.

Specifically, in the present embodiment, the cooking states of different situations of the cooker 20, such as a water cooking state or a water-free cooking state, can be automatically identified through the collected temperature of the pot 30. When the cooker 30 is in a cooking state with less oil smoke generated by stewing, boiling, stewing, steaming and the like, the cooker 20 is in a water cooking state, and the fan of the range hood 10 can be controlled to operate by preset wind power, for example, the fan operates by smaller wind power, so that electric energy can be saved. When the pan 30 is in the cooking state of frying, stir-frying, frying and the like which generates more oil smoke, the pan 20 is in the waterless cooking state, and the wind power operation of the fan of the range hood 10 positively correlated to the current pan temperature can be controlled, for example, the temperature of the pan is higher, and the wind power operation of the fan is larger, so that the oil smoke is completely sucked by the range hood 10.

Referring to fig. 15, in some embodiments, step S20 includes the steps of:

s210, judging whether a boiling section exists according to the temperature of the pot 30;

if yes, S220, determining the cooking state of the cooker 30 as a water cooking state;

The boiling section is understood to be the temperature section reached by the pot 30 when the pot 30 is in the boiling stage with water in the cooking state. It should be noted that when the water in the pot is boiling, the temperature of the water in the pot is maintained at a stable temperature section, and at this time, the heat is transferred to the outer surface of the pot 30, so that the temperature of the outer surface of the pot 30 is also maintained at a stable temperature section. The fluctuation range of the temperature of the outer surface of the pot 30 can be understood as a boiling section. The cooking state with water can be a cooking state with less oil smoke generated by stewing, boiling, stewing, steaming and the like. The waterless cooking state can be a cooking state with more oil smoke generated by frying, stir-frying, frying and the like.

In some embodiments, the force of the wind of the fan of the range hood 10 may be adjusted by the speed of the fan, i.e., the first force and the second force may be achieved by different fan speeds. It can be understood that the range hood 10 of the present embodiment can recognize that the cooking range 20 starts to be turned on by a fire signal fed back to the control device 50 of the range hood 10, and then the fan and the lighting device 16 of the range hood 10 are turned on.

Referring to fig. 23, in some embodiments, the wind power of the fan of the range hood 10 is determined by the rotation speed of the fan of the range hood 10, the rotation speed of the fan of the range hood 10 is obtained according to the current temperature of the pot 30 and the preset relationship between the wind power of the fan of the range hood 10 and the temperature of the pot 30, and the control method further includes:

and S620, judging whether the absolute value of the difference between the rotating speed of the fan of the range hood 10 corresponding to the current temperature of the cooker 30 and the rotating speed of the fan of the range hood 10 is greater than or equal to a preset difference, if so, S622, adjusting the rotating speed of the fan of the range hood 10 to the rotating speed of the fan of the range hood 10 corresponding to the current temperature of the cooker 30, and if not, S624, keeping the rotating speed of the fan of the range hood 10 unchanged.

The control device 50 is configured to determine whether an absolute value of a difference between a rotation speed of a fan of the range hood 10 corresponding to the current temperature of the cooker 30 and a rotation speed of the fan of the range hood 10 is greater than or equal to a preset difference, adjust the rotation speed of the fan of the range hood 10 to the rotation speed of the fan of the range hood 10 corresponding to the current temperature of the cooker 30 if the absolute value is greater than or equal to the preset difference, and keep the rotation speed of the fan of the range hood 10 unchanged if the absolute value is not greater than the preset difference.

Thus, the range hood 10 can adjust the rotation speed of the fan in time according to the actual temperature of the pot 30 so that the fan can suck the oil smoke at a proper rotation speed and save electric energy.

It can be understood that, when the collected number of temperatures of the cooker 30 is less than or equal to the preset number, the number of temperatures of the cooker is not enough to determine whether the cooking state of the cooker is in the water cooking state or the water-free cooking state, and at this time, the rotation speed of the fan of the range hood 10 is obtained according to the current temperature of the cooker 30 and the preset relationship between the wind power of the fan of the range hood and the temperature of the cooker 30, for example, a first preset functional relationship between the wind power of the fan of the range hood 10 and the temperature of the cooker 30 may be established, and the rotation speed of the fan of the range hood 10 is obtained through the current temperature of the cooker 30 and the first preset functional relationship.
