Description

Technical Field

[0001] This invention relates to the field of integrated stove technology, specifically providing an integrated stove, cooking equipment, and its control method and controller. Background Technology

[0002] Integrated cooktops combine the functions of a range hood, gas stove, and steam oven, and their compact design and convenient installation have won the favor of many users. However, the steam ovens in most integrated cooktops on the market currently use a fixed single-cavity structure. This design limits cooking flexibility, meaning only one mode can be used at a time. Particularly problematic is that when users only need to prepare a small amount of food, the excessively large cooking space not only leads to low energy efficiency but also results in significant resource waste.

[0003] Existing improvements, such as adding non-removable partitions to the inner pot, while enabling independent operation of the upper and lower or left and right cavities, sacrifice the overall flexibility of the cavity, making it impossible to adjust to a single-cavity mode to cook a large number of ingredients simultaneously according to actual needs. Furthermore, these designs often rely on temperature sensors on the inner pot's sidewalls to monitor temperature, which often fails to accurately reflect the true temperature conditions in the center of the cooking cavity, further impacting cooking performance and energy efficiency.

[0004] Accordingly, a new control method is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to at least solve the problems of poor cooking effect and low energy efficiency of existing cooking equipment.

[0006] In a first aspect, the present invention provides a control method for a cooking device, the cooking device having a cooking cavity, a first fan and a second temperature sensor being disposed on a first sidewall of the cooking cavity, and a second fan and the first temperature sensor being disposed on a second sidewall opposite to the first sidewall, the first temperature sensor being used to acquire a first temperature, the second temperature sensor being used to acquire a second temperature, the first fan and the second fan being arranged in a staggered manner in the vertical direction, and a plurality of heating loads being disposed within the cooking cavity.

[0007] The control method includes:

[0008] The cooking device is operated in a selected baking mode, and a corresponding target temperature is determined based on the selected baking mode, and a corresponding temperature threshold is determined based on the target temperature.

[0009] Obtain the first temperature and the second temperature;

[0010] The center temperature of the cooking cavity is estimated based on the first temperature and the second temperature;

[0011] Compare the center temperature with the temperature threshold;

[0012] Based on the comparison results, the operating parameters of the heating load, the first fan, and the second fan are selectively adjusted.

[0013] In some feasible embodiments of the control method for the cooking equipment described above, the step of "estimating the center temperature of the cooking cavity based on the first temperature and the second temperature" includes:

[0014] The center temperature of the cooking cavity is estimated using formula (1):

[0015] T Z =k1T1+k2T2+b Formula (1)

[0016] Among them, T Z T1 is the center temperature of the cooking cavity, T2 is the first temperature, and k1, k2 and b are constants.

[0017] In some feasible embodiments of the control method for the above-mentioned cooking equipment, the temperature threshold includes a first temperature threshold and a second temperature threshold, the first temperature threshold being less than the second temperature threshold, the heating load including a top electric heater, a first electric heater, and a second electric heater, the first electric heater being disposed around the first fan, and the second electric heater being disposed around the second fan, the phrase "selectively adjusting the operating parameters of the heating load, the first fan, and the second fan based on the comparison results" includes:

[0018] If the center temperature is less than the first temperature threshold, then the top electric heater, the first electric heater, and the second electric heater operate at full power, and the first fan and the second fan reverse direction in the first commutation cycle; or

[0019] If the center temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, then the top electric heater is turned off, and the operating parameters of the first and second electric heaters are selectively adjusted based on the temperature change rate, and the first and second fans are reversed in both directions during the second commutation cycle; or

[0020] If the center temperature is greater than or equal to the second temperature threshold, then the top electric heater, the first electric heater, the second electric heater, the first fan, and the second fan are turned off.

[0021] In some feasible embodiments of the control method for the cooking equipment described above, the phrase "making the first fan and the second fan reverse direction in a first commutation cycle" includes:

[0022] The first and second fans are made to rotate in opposite directions during a first commutation cycle, with the first and second fans rotating in opposite directions; or

[0023] The phrase "to cause the first fan and the second fan to reverse direction during the second commutation cycle" includes:

[0024] The first and second fans are reversed in a second reversing cycle, and the first and second fans rotate in opposite directions.

[0025] In some feasible embodiments of the control method for the cooking equipment described above, the "selective adjustment of the operating parameters of the first electric heater and the second electric heater based on the rate of temperature change" includes:

[0026] Get the previous center temperature and the current center temperature;

[0027] The rate of temperature change was calculated.

[0028] The temperature change rate is compared with a preset temperature change rate threshold.

[0029] Based on the comparison results, the operating parameters of the first electric heater and the second electric heater are selectively adjusted.

[0030] In some feasible embodiments of the control method for the cooking equipment described above, the preset temperature change rate threshold includes a first temperature change rate threshold and a second temperature change rate threshold, wherein the first temperature change rate threshold is equal to zero and less than the second temperature change rate threshold, and the phrase "selectively adjusting the operating parameters of the first electric heating and the second electric heating based on the comparison results" includes:

[0031] If the temperature change rate is less than the first temperature change rate threshold, then at least one of the first electric heater and the second electric heater should have its power and / or duty cycle increased; or

[0032] If the temperature change rate is greater than or equal to the first temperature change rate threshold and less than the second temperature change rate threshold, then the first electric heater and the second electric heater shall operate at their current operating parameters; or

[0033] If the temperature change rate is greater than or equal to the second temperature change rate threshold, then at least one of the first electric heater and the second electric heater shall have its power and / or duty cycle reduced.

[0034] In some feasible embodiments of the control method for the cooking equipment described above, the cooking cavity can be switched between a single cavity and a dual-cavity via a detachable partition. The dual-cavity consists of a first sub-cavity and a second sub-cavity. The first temperature sensor and the first fan correspond to the first sub-cavity, and the second temperature sensor and the second fan correspond to the second sub-cavity.

[0035] The control method for the cooking equipment provided by this invention utilizes two independent temperature sensors throughout the cooking cavity to detect the temperature in different areas. It also incorporates staggered dual fans and performs temperature control based on the center temperature. Since the center temperature is closer to the temperature of the food within the cooking cavity, this avoids the inaccurate temperature monitoring problems caused by relying solely on temperature sensors on the inner wall of the cooking chamber in traditional designs. Furthermore, the dual-fan control further enhances the uniformity of the temperature field within the cooking cavity. Because both temperature control accuracy and temperature field uniformity are significantly improved, the food is heated more evenly during cooking. Therefore, this control method helps improve cooking results, ensuring that the food achieves better taste and appearance.

[0036] Furthermore, the removable partition allows the cooking appliance to flexibly switch between full-cavity and dual-cavity modes. Users can choose to use the full cavity to cook a large quantity of ingredients simultaneously, or divide the cooking cavity into two independent sub-cavities for cooking different ingredients, greatly enhancing cooking flexibility and versatility. When only a small amount of food needs to be processed, users can choose to divide the cooking cavity into two smaller sub-cavities, avoiding energy waste caused by using the entire large cavity. Simultaneously, each sub-cavity is equipped with an independent temperature sensor and heating load, enabling more precise control of the cooking temperature in each area, further improving energy efficiency.

[0037] In a second aspect, the present invention also provides a controller comprising a memory and a processor, the memory being adapted to store a plurality of program codes adapted to be loaded and executed by the processor to perform the control method of the cooking apparatus described in any of the foregoing technical solutions.

[0038] In a third aspect, the present invention also provides a cooking device, the cooking device comprising the controller described in any of the foregoing technical solutions.

[0039] In a fourth aspect, the present invention also provides an integrated stove, which includes the cooking equipment described in any of the foregoing technical solutions.

[0040] Those skilled in the art will understand that, since the cooking equipment and integrated stove are capable of performing the aforementioned control methods, they possess all the technical effects that the aforementioned control methods can achieve, and will not be elaborated further here.

[0047] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the following embodiments are illustrated using an integrated stove as an example, this is not limiting. The technical solution of the present invention is also applicable to individual cooking equipment such as steam ovens, microwave-steam-grill combos, etc. Such changes in application do not deviate from the spirit of the present invention and should all be limited within the scope of protection of the present invention.

[0048] To better illustrate the invention, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that the invention can be practiced without certain specific details.

[0049] In the description of this invention, terms such as "upper," "lower," "inner," "outer," "left," "right," "front," and "rear," which indicate direction or positional relationships, are based on the illustrated directions or positional relationships. This is merely for ease of description and does not indicate or imply that the device to be protected must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the orientations in the following embodiments should not be construed as limitations on this invention. Furthermore, ordinal numbers such as "first" and "second" are for ease of explanation only and are not used to indicate or imply relative importance.

[0050] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] In this invention, "not illustrated" means not shown in the accompanying drawings, and "not labeled" means that there is a corresponding illustration in the accompanying drawings but it is not labeled.

[0052] The following explanation uses an integrated cooktop with a built-in steam oven as an example.

[0053] The integrated stove provided in this embodiment of the invention includes a steam oven, a cooktop (not shown), a range hood (not shown), etc. The steam oven is embedded in the cabinet of the integrated stove, the cooktop is located above the steam oven, and the range hood is located above the cooktop.

[0054] The steam oven includes a cabinet and a door (not shown). The cabinet contains an inner liner that surrounds the cooking cavity. The door is pivotally connected to the cabinet to open or close the cooking cavity, ensuring safety and sealing during the cooking process.

[0055] like Figure 1 As shown, the inner liner 1 includes a left side wall 11, a right side wall 12, a top wall 13, a bottom wall 14, and a back wall (not shown), forming a spacious cooking cavity that provides ample space for various cooking needs. Shelves 5 are installed on both the left side wall 11 and the right side wall 12 of the cooking cavity. The shelves 5 are used to support baking pans (not shown), grill racks (not shown), etc. Figure 1 The shelf 5 shown has five placement positions 51, with the central placement position 51 used to install a partition (not shown). The partition can be inserted into or removed from the placement position 51 along the front-to-back direction of the oven, meaning the partition is detachable from the cooking cavity, allowing the cooking cavity to be converted between a single cavity and a dual-cavity configuration. Specifically, when the partition is placed in the placement position 51, the cooking cavity is divided into a first sub-cavity and a second sub-cavity, with the first sub-cavity located above the second sub-cavity; when the partition is removed from the placement position 51, the cooking cavity is converted from a dual-cavity configuration to a single cavity. A light 4 is also installed on the inner wall of the oven.

[0056] Continue to refer to Figure 1The steam oven is also equipped with a heating load 2 and a temperature sensor group 3. The heating load 2 includes a first hot air unit 21, a second hot air unit 22, a top electric heater, and an evaporation plate 23 (with electric heating). The first hot air unit 21 is located on the left side wall 11 of the inner cavity 1, and the second hot air unit 22 is located on the right side wall 12 of the inner cavity 1. The first and second hot air units 21 and 22 are vertically offset and opposite each other. The top electric heater is located inside the top wall 13 of the inner cavity 1, and the evaporation plate 23 is located inside the bottom wall 14. The temperature sensor group 3 includes a first temperature sensor 31 and a second temperature sensor 32. The first temperature sensor 31 is located on the right side wall 12, opposite to the first hot air unit 21, and the second temperature sensor 32 is located on the left side wall 11, opposite to the second hot air unit 22. The top electric heater serves as the main heat source for the cooking cavity and is typically activated when the steam oven is operating in grilling, baking, or roasting modes.

[0057] Specifically, for ease of description, taking the case where the partition is in the inserted state as an example, the first temperature sensor 31 and the first hot air unit 21 both correspond to the first sub-cavity. The first temperature sensor 31 is installed on the opposite side of the first hot air unit 21 and is used to detect the first temperature, that is, the internal temperature of the first sub-cavity (when the partition is in the inserted state). The second temperature sensor 32 and the second hot air unit 22 both correspond to the second sub-cavity. The second temperature sensor 32 is installed on the opposite side of the second hot air unit 22 and is used to detect the second temperature, that is, the internal temperature of the second sub-cavity (when the partition is in the inserted state). When the partition is not inserted, that is, when the cooking cavity is in the full cavity state, the first temperature measured by the first temperature sensor 31 mainly reflects the temperature of the upper half of the full cavity, and the second temperature measured by the second temperature sensor 32 mainly reflects the temperature of the lower half of the full cavity.

[0058] Furthermore, when the partition is in the inserted state, the top electric heater corresponds to the first sub-cavity, and the evaporation plate 23 corresponds to the second sub-cavity.

[0059] The first hot air unit 21 includes a first fan and a first electric heater. The first electric heater is a ring-shaped coil structure, located near the periphery of the first fan 212 of the first fan. The first electric heater and the first fan 212 are located in a first hot air cavity (not shown), which is formed by the construction of the first fan cover 211 and the left side wall 11 of the inner liner 1. The second hot air unit 22 includes a second fan and a second electric heater. The second electric heater is a ring-shaped coil structure, located near the periphery of the second fan of the second fan. The second electric heater and the second fan are located in a second hot air cavity (not shown), which is formed by the construction of the second fan cover and the right side wall 12 of the inner liner 1. When the first hot air unit 21 is turned on, if only the first electric heater is turned on, it is used to increase the temperature inside the cavity. If both the first fan 212 and the first electric heater are turned on, it can not only increase the temperature inside the cavity but also further promote the uniformity of the temperature field inside the cavity and provide an air blasting function.

[0060] In addition, to promptly determine whether the partition is inserted or not, the steam oven is equipped with an infrared sensor 6, which detects the partition's position. It should be noted that other devices can also be used to detect the partition's position, such as pressure sensors or contact switches.

[0061] As can be seen, due to the large space of the cooking cavity, there will be a certain deviation between the temperature directly measured by the temperature sensor and the actual temperature in the middle of the cooking cavity. This will lead to temperature deviation when temperature control is based on the temperature measured by the temperature sensor, thus failing to achieve the desired cooking effect. In order to improve the cooking effect and the accuracy of temperature control, unlike the temperature control method of existing fixed-cavity steam ovens, this invention provides a temperature control scheme with temperature compensation for variable-cavity steam ovens. This scheme can more accurately reflect the actual temperature near the food in the cooking cavity during the temperature control process, thereby improving the cooking effect.

[0062] The following is combined Figure 2 and Figure 3 The control method provided in the embodiments of the present invention will be described.

[0063] like Figure 1 and Figure 2 As shown in the figure, the control method provided in this embodiment includes:

[0064] S10. The cooking device is operated in the selected baking mode, and the corresponding target temperature is determined based on the selected baking mode, and the corresponding temperature threshold is determined based on the target temperature.

[0065] Specifically, including:

[0066] S101. Run in the selected baking mode, determine the corresponding target temperature based on the selected baking mode, and determine the corresponding temperature threshold based on the target temperature.

[0067] Specifically, when a user selects a specific baking mode, or when a suitable baking mode is automatically selected through image processing or other means, the target temperature corresponding to the selected baking mode is also determined, and consequently, the temperature threshold corresponding to the target temperature is also determined.

[0068] For example, the ideal temperature for grilling chicken legs is 180℃ to 200℃, for grilling meat skewers it's 200℃ to 210℃, for grilling fish it's 180℃ to 220℃, for grilling beef jerky it's 150℃ to 180℃, for grilling bread it's 160℃ to 220℃, and for baking pizza it's 220℃ to 250℃. Based on this, if a user wants to grill meat skewers, they can set the target temperature to 205℃ based on the size of the skewers; or they can directly select the "grill meat skewers" button, with the corresponding target temperature preset to 200℃; or image processing technology can determine if the user wants to grill meat skewers, and the controller can automatically put the device into grill meat skewers mode, with the corresponding target temperature preset to 200℃, and so on.

[0069] It should be noted that in the grill mode, you can grill any kind of food such as meat skewers, chicken legs, chicken wings, dried meat, vegetables, bread, or cakes, or directly use different temperature ranges without being specifically limited to what kind of food to grill. In addition, it can also be air frying (hot air grilling).

[0070] After selecting a specific baking mode, the corresponding temperature threshold is also determined. It is usually determined by fluctuating around 10°C above or below the target temperature. The specific relationship between the temperature threshold and the target temperature is determined during the experimental stage.

[0071] Specifically, the temperature threshold includes a first temperature threshold and a second temperature threshold, wherein the first temperature threshold is less than the second temperature threshold.

[0072] For example, in this embodiment, the selected baking mode is the hot air baking mode, the target temperature is 230°C, the preset cooking time is 30 minutes, the corresponding first temperature threshold is 220°C, and the second temperature threshold is 240°C.

[0073] S20, Obtain the first temperature and the second temperature.

[0074] Specifically, a first temperature is obtained through a first temperature sensor, and a second temperature is obtained through a second temperature sensor.

[0075] S30. Estimate the center temperature of the cooking cavity based on the first temperature and the second temperature.

[0076] Specifically, in this embodiment of the invention, the center temperature of the cooking cavity is estimated using formula (1):

[0077] T Z =k1T1+k2T2+b Formula (1)

[0078] Among them, T Z T1 is the center temperature of the cooking cavity, T2 is the first temperature, and T2 is the second temperature. k1, k2, and b are constants. k1, k2, and b have a preset mapping relationship with the selected baking mode. The specific values ​​are determined through the experimental stage and are related to one or more of the target temperature, heating load type, model, performance, etc. of the corresponding baking mode.

[0079] For example, in pizza baking mode, if the top electric heater, the first electric heater, and the second electric heater are all turned on, then:

[0080] T Z =0.6523T1+0.3985T2-6.524.

[0081] S40. Compare the center temperature with the temperature threshold.

[0082] Specifically, the center temperature is compared with a first temperature threshold and a second temperature threshold, including:

[0083] S401. Determine whether the center temperature is less than the first temperature threshold.

[0084] If yes, it indicates that the current stage is in the preheating stage, at which point the cavity temperature needs to be rapidly increased, and step S102 is executed. If no, it indicates that the current stage has entered the constant temperature stage, and step S402 is executed.

[0085] For example, the first temperature is 85°C, the second temperature is 76°C, and the estimated center temperature is 79°C. Since the center temperature is less than 220°C, the current stage is the heating stage, so the top electric heater, the first electric heating tube and the second electric heating tube are running at full power (maximum power), and the first fan and the second fan are running with a first reversing cycle of 30 seconds, that is, changing direction once every 30 seconds.

[0086] Furthermore, the first and second fans are made to rotate in opposite directions; for example, if the first fan rotates clockwise, the second fan rotates counterclockwise. When reversing, the first and second fans reverse direction simultaneously, that is, the first fan rotates counterclockwise and the second fan rotates clockwise.

[0087] S402. Determine whether the center temperature is less than the second temperature threshold.

[0088] If not, that is, if the center temperature is greater than or equal to the second temperature threshold, it indicates that the temperature has exceeded the upper temperature limit, and then step S501 is executed.

[0089] If so, that is, the center temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, it indicates that the current stage is a constant temperature stage, and then step S502 is executed.

[0090] S50. Based on the comparison results, selectively adjust the operating parameters of the heating load, the first fan, and the second fan.

[0091] Specifically, including:

[0092] S501, shut down the top electric heater, the first electric heater, the second electric heater, the first fan, and the second fan.

[0093] Specifically, since the center temperature has exceeded the upper temperature limit, in order to prevent over-baking and burning, it is necessary to quickly reduce the cavity temperature. At this time, the top electric heater, the first electric heater, the second electric heater, the first fan, and the second fan are turned off. Then return to step S20.

[0094] S502, turn off the top electric heating, selectively adjust the operating parameters of the first and second electric heating based on the temperature change rate, and make the first and second fans reverse direction in a second commutation cycle.

[0095] Specifically, the top electric heating is turned off, the first and second fans are reversed in a second reversing cycle, and then the operating parameters of the first and second electric heating are further adjusted based on the temperature change rate of the center temperature after the adjustment parameters.

[0096] Specifically, it may include the following steps:

[0097] S5021, Turn off the top electric heating and reverse the first and second fans in the second reversing cycle.

[0098] Specifically, heat generation is reduced by turning off the top electric heating and by adjusting the reversing cycle of the first and second fans to change the degree of agitation of the hot air inside the cavity.

[0099] For example, after the top electric heating is turned off, the first and second fans are reversed every 20 seconds, and the first and second fans rotate in opposite directions.

[0100] S5022, Obtain the first temperature, the second temperature, and the previous center temperature.

[0101] Specifically, a first temperature is obtained through a first temperature sensor, a second temperature is obtained through a second temperature sensor, and the previous center temperature is obtained through historical records.

[0102] S5023, Estimate the current center temperature and calculate the rate of temperature change.

[0103] Specifically, the current center temperature is calculated according to formula (1), referring to step S30. After calculating the current center temperature, the temperature change rate is calculated based on the current center temperature and the previous center temperature. Temperature change rate = (current center temperature - previous center temperature) / detection time interval.

[0104] S5024. Determine whether the rate of temperature change is less than the first temperature change rate threshold.

[0105] Specifically, the first and second temperature change rate thresholds are preset. A large change rate indicates large temperature fluctuations, while a small change rate indicates small temperature fluctuations. Therefore, to ensure that the temperature fluctuation within the cavity remains within a certain range, the first and second temperature change rate thresholds need to be preset during the experimental phase. In this embodiment, the first temperature change rate threshold is equal to zero, and the second temperature change rate threshold is greater than zero.

[0106] If so, that is, the rate of temperature change is less than zero, it indicates that the temperature is decreasing. At this time, it is necessary to increase the heat generation, and then proceed to step S5026.

[0107] If not, i.e. the calculated temperature change rate is greater than or equal to the first temperature change rate threshold, then proceed to step S5025.

[0108] S5025. Determine whether the rate of temperature change is less than the second temperature change rate threshold.

[0109] If so, that is, the temperature change rate is greater than or equal to the first temperature change rate threshold and less than the second temperature change rate threshold, then proceed to step S5027.

[0110] If not, i.e., the rate of temperature change is greater than or equal to the second rate of temperature change threshold, then proceed to step S5028.

[0111] S5026, Increase the power and / or duty cycle of one of the first electric heater and the second electric heater.

[0112] For example, if the power of the first electric heater and the second electric heater cannot be changed, the duty cycle of the first electric heater and the second electric heater is adjusted. For example, before the adjustment, the first electric heater and the second electric heater run for 15 seconds every 30 seconds, and after the adjustment, the first electric heater and the second electric heater run for 20 seconds every 30 seconds, and the process returns to step S5022 to perform temperature detection again.

[0113] S5027, Set the first and second electric heaters to operate at their current operating parameters.

[0114] Specifically, if the first electric heater and the second electric heater run for 15 seconds every 30 seconds in the current stage, then the current state is maintained and the process continues, while returning to step S5022 to perform temperature detection again.

[0115] S5028, reduce the power and / or duty cycle of one of the first electric heater and the second electric heater.

[0116] For example, if before the adjustment, the first and second electric heaters ran for 15 seconds every 30 seconds, and after the adjustment, the first and second electric heaters run for 10 seconds every 30 seconds. Then, proceed to step S60.

[0117] S60. Determine whether the preset cooking time has been reached.

[0118] For example, when entering the baking mode and starting the timer, if the current time has not reached the preset cooking time, such as 30 minutes, then return to step S5022.

[0119] If the preset cooking time is reached, indicating that cooking is complete, the cooking program will end after all heating loads and fans are turned off.

[0120] The control method for the cooking equipment provided by this invention utilizes two independent temperature sensors throughout the cooking cavity to detect the temperature in different areas. It also incorporates staggered dual fans and performs temperature control based on the center temperature. Since the center temperature is closer to the temperature of the food within the cooking cavity, this avoids the inaccurate temperature monitoring problems caused by relying solely on temperature sensors on the inner wall of the cooking chamber in traditional designs. Furthermore, the dual-fan control further enhances the uniformity of the temperature field within the cooking cavity. Because both temperature control accuracy and temperature field uniformity are significantly improved, the food is heated more evenly during cooking. Therefore, this control method helps improve cooking results, ensuring that the food achieves better taste and appearance.

[0121] Furthermore, the present invention also provides a controller including a memory and a processor, the memory being adapted to store a plurality of program codes, the program codes being adapted to be loaded and run by the processor to perform the control method of the cooking apparatus of the foregoing embodiments.

[0122] In the description of this invention, "processor" can include hardware, software, or a combination of both. A processor can be a central processing unit, microprocessor, image processor, digital signal processor, or any other suitable processor. A processor has data and / or signal processing capabilities.
