Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a smoke control method and system. Background Art

[0002] During the cooking process, a large amount of oil smoke is generated, which needs to be sucked away by a smoke extraction device. Otherwise, the oil smoke will be adsorbed on the walls, stoves or other objects in the kitchen, requiring manual cleaning again, causing inconvenience.

[0053] Figure 2 This is a system block diagram of a smoking control system according to an embodiment of the present application;

[0054] In the figure, 201 is an acquisition module; 202 is a processing module; 3 is a control module. DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-2 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0056] The present application embodiment discloses a method for controlling smoking. Figure 1 As an implementation method of a smoking control method, a smoking control method includes the following steps:

[0057] Step 101: Obtain temperature data of the cookware.

[0058] Step 102: Obtain the current cooking state of the cookware based on the temperature data.

[0059] Step 103: Control the range hood to match the current cooking state.

[0060] Specifically, an infrared sensor can be installed above the pot heating device (which can be a burner, induction cooker, or other device capable of heating pots). When a user places a pot on the pot heating device, the infrared sensor detects the pot's temperature. The infrared sensor can communicate with the processor, either via wired or wireless communication. When the infrared sensor is turned on, it sends the detected temperature data to the processor, which then acquires the pot's temperature data. The processor then processes the acquired temperature data to determine the pot's current cooking state, and then controls the range hood gear to match the current cooking state. The range hood's power output can then be automatically adjusted based on the cooking state, improving the user experience.

[0061] As another embodiment of the smoke control method, obtaining the current cooking state of the cookware based on temperature data includes: obtaining, based on current N sets of temperature data, a temperature average of the N sets of temperature data and a number of times n when the temperature average is between two adjacent sets of temperature data in the N sets of temperature data; obtaining, based on the N sets of temperature data, a maximum temperature difference in the N sets of temperature data; and determining that the cookware is in a first state when the number n is greater than a preset number, the temperature average is greater than a preset first temperature value, and the maximum temperature difference is within a preset first temperature range;

[0062] Controlling the range hood gear to match the current cooking state includes: when it is determined that the cookware is in the first state and at least meets the first characteristic condition, controlling the range hood to operate at the first gear, and the wind speed corresponding to the range hood operating at the first gear is the maximum wind speed set for the range hood.

[0063] Specifically, the value of N can be configured as needed, for example, N can be 15. The processor obtains the average temperature value of the N sets of temperature data based on the current N sets of temperature data. For example, the N sets of temperature data can be accumulated and summed, and the result of the accumulation and summation can be divided by N to obtain the average temperature value. Temperature data is processed according to a time sequence. For example, N sets of temperature data include a first set, a second set, and so on. After the N sets of temperature data are processed, the original first set of temperature data is discarded, and the original second set of temperature data is used as the new first set of temperature data. The temperature data of the remaining sets are processed accordingly, and the newly obtained temperature data is used as the final set of temperature data, thereby forming a new set of N sets of temperature data. "The average temperature value is between two adjacent sets of temperature data in the N sets" can be understood as: two adjacent sets of temperature data, one of which is greater than the average temperature value and the other is less than the average temperature value. The processor accumulates the number of times the average temperature value is between the two adjacent sets of temperature data in the N sets of temperature data to obtain a number n. The maximum temperature difference among the N sets of temperature data can be understood as the difference between the temperature data with the largest value and the temperature data with the smallest value in the N sets of temperature data. The first state indicates stir-frying in progress, and the first temperature range corresponds to the temperature range of the cookware when the user stirs. When the number n exceeds a preset number, the average temperature is greater than a preset first temperature value, and the maximum temperature difference is within the preset first temperature range, the processor determines that the cookware is in the first state. At this point, controlling the range hood gear to match the current cooking state includes: upon determining that the cookware is in the first state and meets the first characteristic condition, controlling the range hood to operate in the first gear. The first gear is set as the maximum gear of the range hood, and the corresponding wind speed when the range hood operates in the first gear is the maximum wind speed set for the range hood. Since stir-frying easily generates oil smoke, the processor controls the range hood to operate in the first gear to meet the need to absorb oil smoke during stir-frying.

[0064] As a specific implementation of a smoking control method, the method further includes:

[0065] When the cookware is in the first state, based on M consecutive groups of temperature data among the currently acquired N groups of temperature data, it is determined whether each group of temperature data in the first group a of the M groups of temperature data is greater than each group of temperature data in the last group b, and whether the difference between any temperature data in the first group a of temperature data and any temperature data in the last group b of temperature data is greater than a preset first amplitude value; if so, it is determined that the cookware is in the second state;

[0066] When the cookware is not in the first state, based on M consecutive groups of temperature data among the currently acquired N groups of temperature data, it is determined whether each group of temperature data in the first group a of the M groups of temperature data is greater than each group of temperature data in the last group b, and whether the difference between any temperature data in the first group a of temperature data and any temperature data in the last group b of temperature data is greater than a preset second amplitude value; if so, it is determined that the cookware is in the second state; and the second amplitude value is less than the first amplitude value;

[0067] When the cookware is in the second state and the temperature data obtained before entering the second state is greater than the preset second temperature value, the range hood is controlled to operate at the first gear, and the wind speed corresponding to the range hood operating at the first gear is the set maximum wind speed of the range hood;

[0068] When the cookware is in the second state and the temperature data obtained before entering the second state is less than a preset third temperature value, the range hood is controlled to operate at the second gear; the wind speed corresponding to the range hood operating at the second gear is the minimum wind speed set for the range hood; the third temperature value is less than the second temperature value; and

[0069] When the cookware is in the second state and the temperature data obtained before entering the second state is not less than the third temperature value and not greater than the second temperature value, the range hood is controlled to maintain the current gear.

[0070] Specifically, after the processor determines that the cookware is in the first state, it continues to process the cookware's temperature data in real time to determine the cookware's state. The M sets of temperature data are consecutive, with M not greater than N. If the cookware was previously in the first state, each set of temperature data in the first a group is greater than each set of temperature data in the second b group, and the difference between any temperature data in the first a group and any temperature data in the second b group is greater than a preset first amplitude value, the cookware has entered the second state, which can be understood as a "jump-down state." Alternatively, if the cookware is not in the first state, each set of temperature data in the first a group is greater than each set of temperature data in the second b group, and the difference between any temperature data in the first a group and any temperature data in the second b group is greater than a preset second amplitude value, the cookware has entered the second state, and the first amplitude value is different from the second amplitude value, with the first amplitude value being greater than the second amplitude value. Thereafter, if the cookware is in the second state and the temperature data acquired before entering the second state is greater than the preset second temperature value, the processor controls the range hood to operate in the first gear. When the cookware is in the second state and the temperature data obtained before entering the second state is less than the preset third temperature value, the processor controls the range hood to operate at the second gear, and the wind speed corresponding to the machine running at the second gear is the minimum wind speed set for the range hood; when the cookware is in the second state and the temperature data obtained before entering the second state is not less than the third temperature value and not greater than the second temperature value, the range hood is controlled to maintain the current gear.

[0071] As another embodiment of a smoking control method, when the acquired temperature data is within a preset second temperature range and lasts for a preset first time period, based on M consecutive groups of temperature data among the currently acquired N groups of temperature data, it is determined whether each group of temperature data in the latter b groups of the M groups of temperature data is greater than each group of temperature data in the former a groups, and whether the difference between any temperature data in the latter M / 2 groups of temperature data and any temperature data in the former M / 2 groups of temperature data is greater than a preset third amplitude value; if so, it is determined that the cookware is in a third state; the third amplitude value is less than the first amplitude value and the second amplitude value;

[0072] When the cookware is in the third state and the current temperature data is less than the preset fourth temperature value and greater than the preset fifth temperature value, the range hood is controlled to operate at the first gear; the wind speed corresponding to the range hood operating at the first gear is the set maximum wind speed of the range hood; the fourth temperature value is greater than the fifth temperature value;

[0073] When the cookware is in the third state and the current temperature data is greater than the fourth temperature value, the range hood is controlled to operate at the third gear; the wind speed when the range hood is operating at the third gear is less than the wind speed when the range hood is operating at the first gear, and the wind speed when the range hood is operating at the third gear is greater than the wind speed when the range hood is operating at the second gear.

[0074] Specifically, when the acquired temperature data is in the preset second temperature range and lasts for the preset first time period, each group of temperature data in the latter group b in the M groups of temperature data is greater than each group of temperature data in the former group a and the difference between any temperature data in the latter M / 2 groups of temperature data and any temperature data in the former M / 2 groups of temperature data is greater than the preset third amplitude value, then the processor determines that the cookware is in the third state. The third state can be understood as a "jump state". When the cookware is in the third state and the current temperature data is less than the preset fourth temperature value and greater than the preset fifth temperature value, the range hood is controlled to operate in the first gear; when the cookware is in the third state and the current temperature data is greater than the fourth temperature value, the range hood is controlled to operate in the third gear; the wind speed when the range hood is running in the third gear is less than the wind speed when the range hood is running in the first gear, and the wind speed when the range hood is running in the third gear is greater than the wind speed when the range hood is running in the second gear.

[0075] As another embodiment of a smoking control method, the method further includes:

[0076] Comparing the N sets of temperature data currently obtained, if the temperature data obtained satisfies the first data state and maintains the preset number of sets continuously, it is determined that the cookware is in the fourth state;

[0077] When the cookware is in the fourth state and the current temperature data is greater than the preset sixth temperature value, if the maximum difference of the current N sets of temperature data is less than the preset difference, the range hood is controlled to operate at the third gear, and the wind speed corresponding to the range hood operating at the third gear is between the maximum wind speed and the minimum wind speed set for the range hood;

[0078] When the cookware is in the fourth state and the current temperature data is greater than the preset seventh temperature value and less than the sixth temperature value, if the current moment is within the preset second time length for the range hood to exit the first state, the range hood is controlled to operate at the third gear; if the current moment is not within the preset second time length for the range hood to exit the first state, the range hood is controlled to operate at the second gear; the wind speed corresponding to the range hood operating at the second gear is the minimum wind speed set for the range hood;

[0079] The first data state includes: when the first group of temperature data in the latest N groups of temperature data is less than the last group of temperature data, the difference between the first group of temperature data and the last group of temperature data is in a preset third interval, and in these M groups of data, the kth group of temperature data is less than or equal to the k+nth group of temperature data, the jth group of temperature data is less than or equal to the j+nth group of temperature data, n≥2; and the first group of temperature data is the minimum value in the latest M groups of temperature data.

[0080] Specifically, the fourth state can be understood as a "slow rising state". The processor controls the range hood to operate at different gears according to the temperature data of the fourth state, thereby being able to achieve different working powers of the range hood according to different cooking states.

[0081] As another embodiment of the smoking control method, the method further includes:

[0082] Comparing the currently acquired N sets of temperature data, if the acquired temperature data satisfies the second data state and persists for a preset number of sets, it is determined that the cookware is in the fifth state; the left endpoint of the third interval is the same as the left endpoint of the fourth interval, and the right endpoint of the third interval is greater than the right endpoint of the fourth interval;

[0083] When the cookware is in the fifth state and the current temperature data is lower than the preset eighth temperature value, the range hood is controlled to operate at the second gear; the wind speed corresponding to the range hood operating at the second gear is the minimum wind speed set for the range hood;

[0084] When the cookware is in the fifth state, the current temperature data is greater than the preset eighth temperature value and the range hood is currently operating at the first gear, the range hood is controlled to operate at the third gear; the wind speed corresponding to the range hood operating at the first gear is the maximum wind speed set for the range hood; the wind speed corresponding to the range hood operating at the third gear is between the maximum wind speed and the minimum wind speed set for the range hood;

[0085] The second data state includes: when the first group of temperature data in the latest N groups of temperature data is less than the last group of temperature data, and the difference between the first group of temperature data and the last group of temperature data is in a preset fourth interval; and in these N groups of data, the kth group of temperature data is less than or equal to the k+nth group of temperature data, the jth group of temperature data is less than or equal to the j+nth group of temperature data, and n≥2.

[0086] Specifically, the fifth state can be understood as a "slow-down state." If, among the latest M sets of temperature data, or among the latest N sets of temperature data, the first set of temperature data is less than the last set of temperature data, and the difference between the first and last sets of temperature data is within a preset fourth interval; and, among these N sets of temperature data, the kth set of temperature data is less than or equal to the k+nth set of temperature data, and the jth set of temperature data is less than or equal to the j+nth set of temperature data, and this continues for a preset number of sets, the processor determines that the cookware is in the fifth state. When the cookware is in the fifth state and the current temperature data is less than a preset eighth temperature value, the processor controls the range hood to operate in the second gear. When the cookware is in the fifth state, the current temperature data is greater than the preset eighth temperature value, and the range hood is currently operating in the first gear, the processor controls the range hood to operate in the third gear.

[0087] As another embodiment of the smoking control method, the method further includes:

[0088] When the absolute value of the difference between any one of the N sets of temperature data and the average temperature value is less than a preset ninth temperature value, the cookware is determined to be in the sixth state;

[0089] When the cookware is in the sixth state and the current temperature data is in the preset fifth interval, the range hood is controlled to operate at the third gear;

[0090] When the cookware is in the sixth state and the current temperature data is lower than the preset ninth temperature, if the current moment is within the preset second time length for the range hood to exit the first state, the range hood is controlled to operate at the third gear; if the current moment is not within the preset second time length for the range hood to exit the first state, the range hood is controlled to operate at the second gear.

[0091] Specifically, the sixth state can be understood as the "pot-moving and low-heat state". When the pot is in the sixth state and the current temperature data is in the preset fifth interval, the range hood is controlled to operate at the third gear;

[0092] When the cookware is in the sixth state and the current temperature data is lower than the preset ninth temperature, if the current moment is within the preset second time length for the range hood to exit the first state, the range hood is controlled to operate at the third gear; if the current moment is not within the preset second time length for the range hood to exit the first state, the range hood is controlled to operate at the second gear.

[0093] As another embodiment of the smoking control method, the method further includes:

[0094] After determining that the cookware is in the second state, if the cookware satisfies a third characteristic condition, determining that the cookware exits the second state;

[0095] After determining that the cookware is in the third state, if the cookware satisfies a fourth characteristic condition, determining that the cookware exits the third state;

[0096] After determining that the cookware is in the fourth state, if the cookware satisfies the fifth characteristic condition, determining that the cookware exits the fourth state;

[0097] After determining that the cookware is in the fifth state, if the cookware satisfies a sixth characteristic condition, determining that the cookware exits the fifth state;

[0098] After determining that the cookware is in the sixth state, if the cookware satisfies the seventh characteristic condition, determining that the cookware exits the sixth state;

[0099] After determining that the cookware is in the seventh state, if the cookware satisfies an eighth characteristic condition, the cookware is determined to have exited the seventh state.

[0100] As another implementation of a smoking control method, when controlling the range hood to switch to different gears, if the time interval between the current moment and the last gear switch is less than a preset third time length, the gear switch is performed after waiting for the third time length.

[0101] Specifically, through the above-mentioned setting, the frequent switching of the gears of the range hood can be avoided, thereby improving the user experience.

[0102] This application also provides a smoking control system, comprising:

[0103] An acquisition module 201 is used to acquire temperature data of the cookware;

[0104] The processing module 202 is configured to obtain the current cooking state of the cookware based on the temperature data; and
