[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of a cooking appliance provided in an embodiment of the present application. The cooking appliance 100 includes a cooking cavity 110, a smoke device 120 for generating smoke, and a heating element 130. Through the cooperation of the cooking cavity 110, the smoke device 120 for generating smoke, and the first heating element 130, a smoke cooking function can be achieved. The cooking appliance 100 can be an air fryer.

[0025] The cooking cavity 110 is used to place food therein for cooking.

[0026] The smoke device 120 is used to generate smoke. In some embodiments, the smoke device 120 may be a smoke generator capable of generating smoke. In other embodiments, the smoke device 120 includes a smoke box and a sub-heating element, and the sub-heating element is used to heat the smoke box so that the smoke box generates smoke. Specifically, when the sub-heating element heats the smoke box with a first power, the smoke box will generate smoke, and when the sub-heating element heats the smoke box with a second power or when the sub-heating element is not working, the smoke box will not generate smoke, wherein the second power is greater than the first power.

[0027] For example, a combustible material that can generate smoke when heated, such as charcoal, can be placed in the smoke box. When the sub-heating element heats the smoke box, the combustible material burns to generate smoke. By controlling the heating power of the sub-heating element, the smoke box can be controlled to generate smoke or not. In some embodiments, the smoke box can be a detachable structure to facilitate replacement of the combustible material in the smoke box or to facilitate cleaning of the smoke box.

[0028] The heating element 130 is used to generate heat to heat the cooking cavity 110. The heating element 130 may be one or more, and the heating element may include but is not limited to an annular dry-burning tube, an infrared heating plate, and a positive temperature coefficient (PTC) heating element.

[0029] In some embodiments, see Figure 2 The cooking appliance 100 further includes a fan 140. The fan 140 may include a motor and a fan blade. The rotation of the motor drives the fan blade to rotate. The fan 140 is used to blow the smoke generated by the smoke device 120 and the heat generated by the heating element 130 toward the cooking cavity 110 to make the temperature and smoke in the cooking cavity 110 uniform and to prevent the heat and smoke from overflowing the cooking cavity 110 as much as possible.

[0030] For some examples, see Figure 3 The cooking device 100 includes a heating element 130, and the smoke device 120 is a smoke generator. The heating element 130 can be arranged above the cooking cavity 110, and the fan 140 is arranged above the heating element 130 and facing the heating element 130 to blow the heat generated by the heating element 130 into the cooking cavity 110 to make the temperature in the cooking cavity 110 uniform while avoiding the heat in the cooking cavity 110 from overflowing as much as possible. The smoke device 120 can be arranged above the cooking cavity 110 and below the fan 140 and on one side (for example, the left or right side) of the heating element 130. The fan 140 can blow the smoke generated by the smoke device 120 into the cooking cavity 110 to perform smoke cooking on the food in the cooking cavity 110.

[0031] For some examples, see Figure 4The cooking device 100 includes two heating elements 131 and 132, and the smoke device 120 is a smoke generator. The heating element 131 is arranged above the cooking cavity 110, and the heating element 132 is arranged below the cooking cavity 110. The fan 140 is arranged above the heating element 131 and faces the fan 140 to blow the heat generated by the heating element 131 and the heating element 132 into the cooking cavity 110 to make the temperature in the cooking cavity 110 uniform. The smoke device 120 is arranged above the cooking cavity 110 and below the fan 140 and on one side (for example, the left or right side) of the heating element 120. The fan 140 can blow the smoke generated by the smoke device 120 into the cooking cavity 110 to perform smoke cooking on the food in the cooking cavity 110. In this embodiment, the heating element 131 can be an annular dry-burning tube, and the heating element 132 can be an annular dry-burning tube or an annular infrared plate. Compared with the annular dry-burning tube, the annular infrared disk does not need to be preheated and can shorten the heating time. In order to reduce the cooking time, the heating element 132 can be set as an annular infrared disk.

[0032] As an example, the control circuit in the smoke generator is as follows Figure 5 As shown, through Figure 5 The control circuit of the smoke generator shown can control the smoke generator to generate smoke or not generate smoke. Among them, ACN represents the interface of alternating current, and GND represents the ground wire. OUT represents the single plug connected to the smoke generator. The switch REL151 is used to control the smoke generator to be turned on or off. The rectangle between 1 and 2 represents the low-voltage coil of the relay, and 1, 2, 3, and 4 represent the four pins of the relay respectively. +12V represents a 12-volt voltage. ZD151 represents a voltage-stabilizing diode, and D151 represents a clamping diode. R151 represents a pull-down resistor, which is used to release the current in the circuit to the ground, and plays a voltage dividing and anti-interference role. BCE represents the three pin ports of the transistor, and the resistor between BCE represents the internal resistance of the transistor. The I / O port represents the input and output port of the single-chip microcomputer. The single-chip microcomputer controls the smoke generator to be turned on (generating smoke) or off (not generating smoke) through the I / O port, the transistor, the relay, and the switch REL151 in turn.

[0033] For some examples, see Figure 6 The cooking device 100 includes a heating element 130, and the smoke device 120 includes a smoke box 121 and a sub-heating element 122. The heating element 130 is arranged above the cooking cavity 110, and the fan 140 is arranged above the heating element 130 and facing the heating element 130 to blow the heat generated by the heating element 130 into the cooking cavity 110 to make the temperature in the cooking cavity 110 uniform. The smoke box 121 is arranged below the cooking cavity 110, and the sub-heating element 122 is arranged below the smoke box 110 to heat the smoke box 121 so that the smoke box 121 generates smoke.

[0034] In some embodiments, the cooking appliance 100 further includes a smoke sensor, which can be disposed near the smoke device 120 or above the cooking cavity 110. The smoke sensor is used to detect the gas and smoke concentration in the cooking cavity 110. In addition, the smoke sensor can also be used to detect carbon monoxide. For example, the smoke sensor can be Figure 7 The smoke detection circuit shown in the figure performs smoke detection. Figure 7 As shown in the figure, CN061 represents a socket, +5V represents a 5V voltage regulator, R061, R064, R062 and C061 are preset resistors and capacitors for converting the smoke concentration detected by the smoke sensor into a digital signal, and the I / O port represents the input and output port of the microcontroller. Specifically, the smoke sensor has a mapping table of smoke concentration values ​​and resistance values. When the smoke sensor detects a smoke concentration value, the target resistance value corresponding to the smoke concentration value is determined, and the target resistance value is input into the Figure 7 The circuit shown can calculate the voltage value corresponding to the target resistance value. The voltage value is converted into a digital signal through the I / O port, and the digital signal is used for smoke concentration detection. It should be noted that Figure 7 The circuit shown and Figure 5 The circuits shown can be integrated on one circuit board according to actual needs, or can be deployed on different circuit boards respectively, and no specific limitation is made here.

[0035] In some embodiments, the cooking appliance 100 further includes a temperature sensor, which may be disposed above the cooking cavity 110 and on one side of the heating element above the cooking cavity 110. The temperature sensor is used to detect the temperature in the cooking cavity 110. The temperature sensor may be a negative temperature coefficient (NTC) sensor or a thermocouple sensor. Since thermocouple sensors are more expensive than NTC sensors, are easily interfered with, and the detection accuracy is affected by the ground wiring, NTC sensors are usually used as temperature sensors, and NTC temperature sensors have higher temperature sensing accuracy.

[0036] In some embodiments, the smoke device 120 includes a smoke box and a sub-heating element, and the cooking appliance 100 includes a temperature sensor, which can be arranged near the sub-heating element to detect the temperature of the sub-heating element and use the temperature of the sub-heating element as the real-time temperature in the cooking cavity 110.

[0037] In some embodiments, the smoke device 120 includes a smoke box and a sub-heating element, and the cooking appliance 100 includes two temperature sensors, one of which can be arranged near the sub-heating element and used to detect the temperature of the sub-heating element, and the other temperature sensor can be arranged near the heating element 130 and used to detect the temperature of the heating element 130. The average value of the temperatures detected by the two temperature sensors can be used as the real-time temperature in the cooking cavity 110.

[0038] The control method of the cooking appliance in the embodiment of the present application can be applied to the cooking appliance or the control device of the cooking appliance. Next, the control method of the cooking appliance in the embodiment of the present application will be introduced.

[0039] See also Figure 8 , Figure 8 1 is a flow chart of a cooking appliance control method provided by an embodiment of the present application. The cooking appliance control method may include the following steps S110 to S130.

[0040] Step S110: In response to the cooking start instruction, the smoke device and the heating element are controlled to operate.

[0041] The cooking start instruction refers to an instruction for starting the smoke cooking function. The cooking appliance has multiple cooking functions. For example, the multiple cooking functions may include but are not limited to air frying, baking, and smoking functions. In some embodiments, each cooking function corresponds to a button. When the user presses the button for starting the smoke cooking function, the control device corresponding to the button will generate a cooking start instruction for smoke cooking. In other embodiments, the cooking appliance has a voice recognition function. Each cooking function may correspond to at least one keyword related to the cooking function. If the cooking appliance recognizes that the user says at least one keyword related to smoke cooking, such as "smoke", a cooking start instruction for smoke cooking may be generated.

[0042] In response to the cooking start instruction, the smoke device is controlled to continuously generate smoke, so as to smoke the food in the cooking cavity. In some embodiments, the smoke device is a smoke generator, which can be used, for example, Figure 5 The control circuit of the smoke generator shown in the figure is used to control the smoke generator to (continuously) open to (continuously) generate smoke. For a specific description of the control circuit, please refer to the above description of Figure 5 In some other embodiments, the smoke generator includes a smoke box and a sub-heating element, and the sub-heating element can be controlled to heat the smoke box at a first power (continuously) so that the smoke box (continuously) generates smoke.

[0043] In response to a cooking start instruction, the lowest power level among the multiple power levels of the heating element is obtained; and the heating element is controlled to work at the lowest power level. Controlling the heating element to work at the lowest power level can ensure that the temperature in the cooking cavity is not too high, thereby baking the food in the cooking cavity at a low temperature, avoiding rapid loss of moisture in the food, and improving the taste of the food.

[0044] Step S120: obtaining the real-time temperature and real-time smoke density in the cooking cavity.

[0045] The real-time temperature in the cooking cavity can be detected in real time by a temperature sensor. In some embodiments, if the cooking appliance includes only one temperature sensor, the temperature detected by the temperature sensor is used as the real-time temperature in the cooking cavity. In other embodiments, if the cooking appliance includes at least two temperature sensors, the average value of the temperatures detected by the at least two temperature sensors can be used as the real-time temperature in the cooking cavity.

[0046] The real-time smoke concentration in the cooking chamber can be detected in real time by the smoke sensor.

[0047] Step S130: adjusting the working mode of the smoke device according to the real-time temperature and the real-time smoke concentration until the current cooking is finished and the smoke device and the heating element are turned off.

[0048] In order to achieve accurate control of the temperature and smoke concentration in the cooking cavity, in an embodiment of the present application, a temperature threshold and a smoke concentration threshold are pre-set to control the temperature and smoke concentration in the cooking cavity, thereby taking into account the temperature and smoke concentration in the cooking cavity at the same time. On the one hand, the temperature in the cooking cavity is controlled not to be too high, thereby baking the food in the cooking cavity at a low temperature to avoid rapid loss of moisture in the food, thereby improving the taste of the food; on the other hand, the smoke concentration in the cooking cavity is controlled not to be too high to avoid excessive smoke causing excessive smoking of the food and affecting the taste of the food.

[0049] When the real-time temperature is less than or equal to the temperature threshold, or the real-time smoke concentration is less than or equal to the smoke concentration threshold, the temperature in the cooking cavity is low and the smoke concentration is not dense enough, and it is necessary to continue to heat up and produce smoke. In this case, the smoke device can be controlled to continue to produce smoke, and the heating element can be controlled to work at the above-mentioned lowest power level, so as to quickly accumulate smoke in the cooking cavity, continue to slowly heat the cooking cavity, and smoke and low-temperature bake the food in the cooking cavity.

[0050] When the real-time temperature is greater than the temperature threshold and the real-time smoke concentration is greater than the smoke concentration threshold, the smoke concentration is sufficient. In order to avoid excessive smoke causing excessive smoking of food, in an embodiment of the present application, in response to the real-time temperature being greater than the temperature threshold and the real-time smoke concentration being greater than the smoke concentration threshold, the smoke device is controlled to generate smoke periodically, so that the smoke device generates smoke at a uniform speed, thereby making the smoke concentration in the cooking cavity in a relatively stable state, and the food in the cooking cavity is smoked at a uniform speed, so that the smoke surrounds the food in the cooking cavity to make the food smoked and improve the taste of the food.

[0051] Specifically, the smoke device can be controlled to generate smoke, start timing and obtain the duration of smoke generation; if the duration of smoke generation reaches a first duration, the smoke device is controlled to stop generating smoke, restart timing and obtain the duration of smoke generation; if the duration of smoke generation stops reaches a second duration, the steps of controlling the smoke device to generate smoke, starting timing and obtaining the duration of smoke generation are repeated until the cooking is completed, wherein the second duration is greater than the first duration, for example, the first duration may be 5 seconds and the second duration may be 10 seconds. In some embodiments, the smoke device may be the above-mentioned smoke generator. For a specific description of how to control the smoke generator to generate smoke or not generate smoke, please refer to the above-mentioned relevant parts. In other embodiments, the smoke device may include a fumigation box and a sub-heating element. For a specific description of how to control the sub-heating element to make the fumigation box generate smoke or not generate smoke, please refer to the above-mentioned relevant parts.

[0052] It should be noted that in order to ensure low-temperature baking of the food in the cooking chamber, the heating element is kept working at the lowest power level throughout the process to prevent high temperature from quickly taking away moisture from the food and affecting the taste of the food.

[0053] The judgment condition for the end of this cooking can be set according to actual needs. In some embodiments, it can be determined according to the set cooking time of this cooking. For example, the timing can be started at the beginning of cooking and the timing time can be obtained as the actual cooking time. When the actual cooking time reaches the set cooking time corresponding to this cooking, it is determined that this cooking is over, and the smoke device and the heating element can be turned off at this time. Among them, the set cooking time can be a pre-set time corresponding to the smoke cooking function, or it can be a time selected by the user from multiple time lengths recommended by the cooking appliance before starting cooking. In other embodiments, in response to the user pressing the button to end cooking, it can be determined that this cooking is over, and the smoke device and the heating element can be turned off at this time. Since the set cooking time is usually based on a large number of experimental calibrations, the method of determining the end of cooking according to the set cooking time is better than the method of determining by the user pressing a button, the smoke cooking effect is better.

[0054] Based on step S110 to step S130, the working mode of the smoke device can be adjusted according to the real-time temperature and real-time smoke concentration in the cooking cavity, and the cooking cavity can be smoked for cooking. The temperature and smoke concentration of the smoke cooking can be controlled in real time and accurately, and can be applied to daily smoke cooking. The smoke cooking function of the cooking utensil is newly added, and the function of the cooking utensil is enriched. Compared with the current method of using special smoke cooking equipment for smoke cooking, it is more convenient, the smoke cooking time is shorter, more hygienic, and cleaner. In addition, the current air fryer products only have air frying and baking functions, and the function menu selection is also relatively simple. After using the product, users will feel that the food is relatively dry after cooking and is easy to get angry. After using it several times, they will no longer use it as frequently as using a rice cooker. When the cooking utensil is an air fryer, the air fryer provided in the embodiment of the present application has a smoke cooking function, which can enrich the function of the air fryer, thereby increasing the frequency of use of the air fryer to a certain extent.

[0055] See also Fig. 9 , Fig. 9 FIG. 2 is a flow chart of a cooking appliance control method provided by another embodiment of the present application. The cooking appliance control method may include the following steps S210 to S240.

[0056] Step S210: In response to the cooking start instruction, the smoke device and the heating element are controlled to operate, the set cooking time is obtained, and the actual cooking time is started to be counted.

[0057] In the embodiments of the present application, the set cooking time refers to the cooking time corresponding to the smoking cooking function. In some embodiments, each cooking function of the cooking utensil corresponds to a set cooking time, and the set cooking time can be directly obtained as the set cooking time for this cooking. In other embodiments, each cooking function of the cooking utensil corresponds to multiple set cooking times, and the user can select one of the multiple set cooking times before starting cooking, and the set cooking time selected by the user is used as the set cooking time for this cooking.

[0058] The actual cooking time refers to the total time taken from the start of the smoking cooking to the present. In response to the cooking start instruction, a timer starts timing, and the timing time is obtained as the actual cooking time.

[0059] For the parts not described in detail in step S210, please refer to step S110.

[0060] Step S220: obtaining the real-time temperature and real-time smoke density in the cooking cavity.

[0061] For a detailed description of step S220, please refer to step S120.

[0062] Step S230: adjusting the working mode of the smoke device according to the real-time temperature and the real-time smoke concentration.

[0063] For a detailed description of step S230, please refer to step S130.

[0064] Step S240: In response to the actual cooking time reaching the set cooking time and carbon monoxide existing in the cooking cavity, the smoke device is turned off, and the heating element is controlled to keep working until there is no carbon monoxide in the cooking cavity and the heating element is turned off.

[0065] Considering that carbon monoxide may exist in the smoke generated by the smoke device during the smoking cooking process, in order to ensure the safe use of the cooking appliance, the carbon monoxide in the cooking cavity can be detected by a smoke sensor. When the actual cooking time reaches the set cooking time, the smoke device is turned off. At this time, if carbon monoxide is detected in the cooking cavity, the heating element is controlled to keep working at the lowest power level to continue to heat the cooking cavity at a low temperature. On the one hand, it is to avoid that high-temperature heating of food affects the taste of the food. On the other hand, carbon monoxide can be converted into carbon dioxide by heating, thereby removing carbon monoxide in the cooking cavity to ensure the safe use of the cooking appliance. That is, in this embodiment, by extending the heating time of the cooking cavity, all the carbon monoxide remaining in the cooking cavity can be converted into carbon dioxide, avoiding the situation where carbon monoxide still remains in the cooking cavity after cooking is completed, thereby ensuring the safe use of the cooking appliance.

[0066] If it is detected that there is no carbon monoxide in the cooking cavity when the actual cooking time reaches the set cooking time, the heating element can be turned off to end the cooking.

[0067] Compared with steps S110 to S130, steps S210 to S240 also have the following additional technical effects: when carbon monoxide is detected in the cooking cavity when the actual cooking time reaches the set cooking time, the heating element is controlled to keep working at the lowest power level to continue to heat the cooking cavity at a low temperature. On the one hand, it can avoid that high-temperature heating of food affects the taste of food. On the other hand, carbon monoxide can be converted into carbon dioxide by heating, thereby removing carbon monoxide in the cooking cavity and ensuring the safety of the cooking appliance. By extending the heating time of the cooking cavity, all the carbon monoxide remaining in the cooking cavity can be converted into carbon dioxide, avoiding the situation where carbon monoxide remains in the cooking cavity after cooking is completed, thereby ensuring the safety of the cooking appliance.

[0068] See also Fig.10 , Fig.10 FIG. 2 is a flow chart of a cooking appliance control method provided by another embodiment of the present application. The cooking appliance control method may include the following steps S310 to S330.

[0069] Step S310: In response to the cooking start instruction, the smoke device, the fan and the heating element are controlled to operate.

[0070] In response to the cooking start instruction, the fan is controlled to rotate at a first speed. For example, if the fan includes three gears, high, medium and low, the first speed may be a speed corresponding to the medium gear. The fan is controlled to rotate at the first speed, so that the smoke generated by the smoke device and the heat generated by the heating element can be quickly blown into the cooking cavity, thereby increasing the temperature in the cooking cavity and accumulating the smoke in the cooking cavity.

[0071] For the parts of step S310 that are not described in detail, please refer to step S110 and step S210 .

[0072] Step S320: obtaining the real-time temperature and real-time smoke density in the cooking cavity.

[0073] For a detailed description of step S320 , please refer to step S120 .

[0074] Step S330: According to the real-time temperature and real-time smoke concentration, the working mode of the smoke device and the speed of the fan are adjusted until the cooking is finished and the smoke device, the fan and the heating element are turned off.

[0075] In response to the real-time temperature being greater than the temperature threshold and the real-time smoke concentration being greater than the smoke concentration threshold, the fan is controlled to rotate at a second speed, so that the smoke generated by the smoke device and the heat generated by the heating element are slowly blown into the cooking cavity, and the smoke concentration and temperature in the cooking cavity are uniform, so that the smoke surrounds the food and smokes the food uniformly. The second speed is less than the first speed. For example, if the fan includes three gears of high, medium and low, the first speed may be a speed corresponding to the low gear.

[0076] For the parts not described in detail in step S330, please refer to step S130 and step S230.

[0077] Compared with steps S110 to S130, steps S310 to S330 additionally have the following technical effects: when the real-time temperature is less than or equal to the temperature threshold or the real-time smoke concentration is less than or equal to the smoke concentration threshold, the fan is controlled to rotate at a first speed to quickly blow the smoke generated by the smoke device and the heat generated by the heating element into the cooking cavity, thereby increasing the temperature in the cooking cavity and accumulating the smoke in the cooking cavity; when the real-time temperature is greater than the temperature threshold and the real-time smoke concentration is greater than the smoke concentration threshold, the fan is controlled to rotate at a second speed less than the first speed to slowly blow the smoke generated by the smoke device and the heat generated by the heating element into the cooking cavity, thereby making the smoke concentration and temperature in the cooking cavity uniform, so that the smoke surrounds the food and smokes the food evenly.

[0078] See also Fig.11 , Fig.11 FIG. 4 is a flow chart of a cooking appliance control method provided by another embodiment of the present application. The cooking appliance control method may include the following steps S410 to S440.

[0079] Step S410: In response to the cooking start instruction, the smoke device, the fan and the heating element are controlled to operate, the set cooking time is obtained, and the actual cooking time is started to be counted.

[0080] For a detailed description of step S410 , please refer to step S110 , step S210 , and step S310 .

[0081] Step S420: obtaining the real-time temperature and real-time smoke density in the cooking cavity.

[0082] For a detailed description of step S420, please refer to step S120.

[0083] Step S430: adjusting the working mode of the smoke device and the speed of the fan according to the real-time temperature and the real-time smoke concentration.

[0084] For a detailed description of step S430, please refer to step S130, step S230 and step S330.

[0085] Step S440: In response to the actual cooking time reaching the set cooking time and carbon monoxide existing in the cooking cavity, the smoke device is turned off, and the heating element and the fan are controlled to keep working until there is no carbon monoxide in the cooking cavity and the heating element and the fan are turned off.

[0086] In response to the actual cooking time reaching the set cooking time and the presence of carbon monoxide in the cooking cavity, the fan is controlled to keep rotating at the first speed or the second speed, so that the heat of the heating element can be blown into the cooking cavity, the temperature in the cooking cavity can be evened out, the carbon monoxide can be quickly converted into carbon dioxide, the gas conversion efficiency can be improved, and the cooking time can be reduced. Since the first speed is greater than the second speed, the first speed can be used to blow the heat of the heating element into the cooking cavity faster, the carbon monoxide can be converted into carbon dioxide faster, the gas conversion efficiency can be improved, and the cooking time can be reduced. In addition, the first speed is not the maximum speed, so even if the first speed is used, the heating element continues to heat up, which will not cause the food to cool down and affect the taste of the food.

[0087] If it is detected that there is no carbon monoxide in the cooking chamber when the actual cooking time reaches the set cooking time, the smoke device, the heating element and the fan are directly turned off to end the cooking.

[0088] For the parts not described in detail in step S440, please refer to the above-mentioned step S130, steps S230-S240 and step S330.

[0089] Compared with steps S210 to S240, steps S410 to S440 also have the following additional technical effects: when carbon monoxide is detected in the cooking cavity when the actual cooking time reaches the set cooking time, the fan is controlled to keep rotating at the first speed or the second speed, so as to blow the heat of the heating element into the cooking cavity, even the temperature in the cooking cavity, quickly convert carbon monoxide into carbon dioxide, improve the gas conversion efficiency, and reduce the cooking time.
