[0056] The technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] With the gradual improvement of people's living standards, the requirements for the quality of life are also getting higher and higher. Cooking devices such as steam ovens, ovens, and steam - ovens provide many conveniences for family life. The heating tubes of such cooking devices are usually distributed in the cavity, such as arranged up and down, and some heating tubes are also provided on the back of the cavity. In different cooking modes, different combinations of heating tubes need to be enabled to make the temperature of each part in the cavity reach the expected temperature. In practical applications, taking a steam - oven as an example, the temperature distribution at each position in the steam - oven is different. If the temperature detection of each position is not accurate, the expected cooking effect cannot be achieved. Currently, the steam - ovens on the market mainly use temperature sensors to collect temperature values plus a compensation value to represent the temperature in the cavity. It is difficult to accurately measure the temperature in different regions of the cavity, and it is impossible to achieve precise control of the heating tubes, which affects the cooking effect.

[0058] Based on the above problems, an embodiment of the present invention provides a cooking device, as Figure 1 shown, the cooking device includes: a cavity 2, in which a plurality of heating tubes ( Figure 1 not shown in are distributed), and the cooking device further includes: a control unit 103. The control unit 103 is configured to obtain the cooking mode selected by the user and the target cooking temperature of the food to be cooked; detect the first position of the food to be cooked in the cavity 2; determine each heating tube participating in cooking and its corresponding temperature compensation parameter based on the cooking mode; calculate the target heating temperature of each heating tube participating in cooking respectively based on the target cooking temperature, the positional relationship between each heating tube participating in cooking and the first position, and their corresponding temperature compensation parameters; and control each heating tube participating in cooking to heat according to its corresponding target heating temperature. For the specific working process of the control unit 103, reference can be made to the relevant description in the method embodiment below and will not be elaborated here.

[0059] It should be noted that in the embodiment of the present invention, a steam - oven is taken as an example for the cooking device. In practical applications, the cooking device can also be an oven or other cooking devices with multiple heating tubes, and the present invention is not limited thereto.

[0060] Specifically, in one embodiment, the cooking device further includes: a position detection device disposed in the cavity 2 for collecting the position signal of the food to be cooked in the cavity 2 and sending the position signal to the control unit 103. Exemplarily, the position detection device is an infrared sensor or a camera, and correspondingly, the position signal is an infrared signal or an image signal. Figure 2A and Figure 2B are two different structural schematic diagrams of the steam oven, as Figure 2A shown, the steam oven includes an upward push rod type operation panel 1, a cavity 22, a water purification tank 3, a wastewater tank 4, an upper grill tray A (5, 31), a middle grill tray B (6, 32), a lower grill tray C (7, 33), a top temperature sensor (8, 25), a top heating tube (9, 34), a back temperature sensor (10, 11, 12, 26, 27, 28), a steam generator air outlet (15, 17, 22, 24), a back heating tube (16, 18, 20, 23), a back blower 19, a bottom temperature sensor (14, 30), a bottom heating tube 21, a bottom drain port (13, 29), and a camera 39. As Figure 2B shown, the steam oven includes an upward push rod type operation panel 1, a cavity 22, a water purification tank 3, a wastewater tank 4, an upper grill tray A (5, 31), a middle grill tray B (6, 32), a lower grill tray C (7, 33), a top temperature sensor (8, 25), a top heating tube 9, a back temperature sensor (10, 11, 12, 26, 27, 28), a steam generator air outlet (15, 17, 22, 24), a back heating tube (16, 18, 20, 23), a back blower 19, a bottom temperature sensor (14, 30), a bottom heating tube 21, a bottom drain port 13, 29, and an infrared sensor (34, 35, 36, 37, 38).

[0061] In practical applications, as Figure 2A shown, a camera can be set (the specific number can be flexibly selected according to actual needs) to collect the position image of the food to be cooked, and then the control unit 103 performs image analysis to determine the specific position of the food to be cooked. For example, if the collected position image belongs to the area b1 as Figure 3A shown, then the first position of the food to be cooked is determined as b1; alternatively, as Figure 2B shown, an infrared sensor can be set (the specific number can be flexibly selected according to actual needs) to collect the infrared signal of the food to be cooked, and then the control unit 103 processes the infrared signal to determine the specific position of the food to be cooked. For example, if the infrared sensor detects the infrared signal of the food to be cooked in the area b as Figure 3B shown in the position image, then the first position of the food to be cooked is determined as b. Only by way of example, the present invention is not limited thereto.

[0062] The cooking device provided by the embodiment of the present invention accurately controls the target heating temperature of each heating tube by using the cooking mode selected by the user, the target cooking temperature, and the positional relationship between the food material and each heating tube, so as to ensure that the food material maintains the target cooking temperature during the cooking process. Accurate temperature control can be achieved no matter where the user places the food material in the cooking device, thereby ensuring the cooking effect of the food material and improving the user experience.

[0063] The embodiment of the present invention also provides a heating control method for a cooking device, which is applied to the control unit 103 as shown in Figure 1 shown. As shown in Figure 4 shown, the air conditioner control method specifically includes the following steps:

[0064] Step S101: Obtain the cooking mode selected by the user and the target cooking temperature of the food material to be cooked.

[0065] Among them, the cooking mode includes: steaming mode, baking mode, etc. The target cooking temperature is the temperature value that the user expects the food material to reach in this cooking mode.

[0066] Step S102: Detect the first position of the food material to be cooked in the cavity.

[0067] Specifically, the above-mentioned camera or infrared sensor can be used to collect the position signal corresponding to the food material to be cooked, and then analyze the position signal to determine its corresponding position. Exemplarily, as shown in Figure 2A shown, the steam oven internally has a total of three layers of grill trays, top, back, and bottom module heating components, a top camera, and corresponding temperature sensors, etc. When the user sets the cooking mode and parameters and confirms the start of cooking, the camera will confirm its position coordinates, which consist of two parts: the baking tray (rack) position and which layer of the grill tray it is on (as shown in Figure 3A shown). For example, the position coordinate (b1, A) indicates that it is located at the baking tray b1 position and the grill tray A. As shown in Figure 2B shown, the steam oven internally has a total of three layers of grill trays, top, back, and bottom module heating components, an infrared sensor, and corresponding temperature sensors, etc. The food material position judgment table is as follows:

[0068] Sensor 34 Sensor 35 Sensor 36 Sensor 37 Ingredient position 0 0 0 0 Empty 0 0 0 1 Area a 0 0 1 0 Area b 0 1 0 0 Area c 1 0 0 0 Area d

[0069] When the user sets the cooking mode and parameters and confirms the start of cooking, the infrared sensor will confirm its position coordinates, which consist of two parts: the baking tray (rack) position and which layer of the grill tray it is on (as shown in Figure 3B shown). For example, the position coordinate (a, A) indicates that it is located at the baking tray a position and the grill tray A.

[0070] Step S103: Determine each heating tube participating in cooking and its corresponding temperature compensation parameter based on the cooking mode.

[0071] Specifically, each heating tube participating in cooking can be determined by based on the corresponding relationship between the preset cooking mode and the heating tube; obtain the temperature compensation parameter corresponding to each heating tube participating in cooking in the cooking mode. Among them, there is a corresponding relationship between the heating tubes required for different cooking modes and the temperature compensation parameters corresponding to each heating tube. This corresponding relationship can be obtained in advance according to experience or experiments, and the present invention is not limited thereto.

[0072] Step S104: Based on the target cooking temperature, the positional relationship between each heating tube participating in cooking and the first position, and their corresponding temperature compensation parameters, calculate the target heating temperature of each heating tube participating in cooking respectively.

[0073] Among them, the target heating temperature is the working temperature of the heating tube. Usually, since there is a certain distance between each heating tube and the food to be cooked, the working temperature of the heating tube needs to be higher than the target cooking temperature to ensure that the food is exactly at the target cooking temperature. Therefore, when controlling each heating tube, it is necessary to accurately control its target heating temperature to meet the food cooking temperature requirements and ensure the cooking effect.

[0074] Step S105: Control each heating tube participating in cooking to heat according to its corresponding target heating temperature.

[0075] Specifically, in one embodiment, the above step S104 specifically includes the following steps:

[0076] Step S401: Based on the target cooking temperature, the positional relationship between each heating tube participating in cooking and the first position, and their corresponding temperature compensation parameters, determine the compensation temperature corresponding to each heating tube participating in cooking.

[0077] Step S402: Compensate the target cooking temperature respectively based on the compensation temperature corresponding to each heating tube participating in cooking to obtain the target heating temperature of each heating tube participating in cooking.

[0078] Specifically, by obtaining the second position of the current heating tube participating in cooking; calculating the distance between the first position and the second position; determining the position compensation parameter of the current heating tube based on the distance; calculating the compensation temperature corresponding to the current heating tube based on the position compensation parameter, the target cooking temperature, and the temperature compensation parameter corresponding to the current heating tube.

[0079] Exemplarily, the compensation temperature corresponding to the heating tube is calculated by the following formula (1):

[0080]

[0081] Among them, T NRepresents the compensation temperature of the Nth heating tube, T M Represents the target cooking temperature, a N And A N Represents the position compensation parameter corresponding to the Nth heating tube, m N 、n N Represents the temperature compensation parameter corresponding to the Nth heating tube, and K represents the temperature coefficient.

[0082] The target heating temperature of the current heating tube is the sum of the compensation temperature of the heating tube and the target cooking temperature. Thus, by utilizing the distance between the heating tube and the food material, temperature compensation can be flexibly performed, thereby further improving the accuracy of heating tube temperature control, ensuring the cooking temperature of the food material, enhancing the cooking effect, and bringing a good user experience to the user.

[0083] Specifically, in one embodiment, before performing the above step S104, the heating control method of the cooking device provided by the embodiment of the present invention further includes the following steps:

[0084] Step S201: Detect the current heating temperature corresponding to the current heating tube participating in cooking.

[0085] Step S202: Determine whether the current heating temperature is less than the target cooking temperature.

[0086] Specifically, when the current heating temperature is not less than the target cooking temperature, control the current heating tube to heat according to its corresponding target heating temperature. When the current heating temperature is less than the target cooking temperature, control the current heating tube to operate at full power and return to step S201. Thus, when the heating temperature of the heating tube is low, that is, when the heating tube is in the heating-up stage, no regulation of the heating temperature is performed, and all operate at full power to ensure that the heating tube reaches the target cooking temperature as soon as possible, shorten the heating-up time, and save the computing resources of the control unit, improving the operating efficiency of the steam oven.

[0087] Specifically, in one embodiment, after performing the above step S104, the heating control method of the cooking device provided by the embodiment of the present invention further includes the following steps:

[0088] Step S301: When it is monitored that each heating tube participating in cooking has reached its corresponding target heating temperature, control each heating tube participating in cooking to alternately operate at its respective current operating power in each operating cycle until the cooking ends.

[0089] Specifically, when all the heating tubes reach their respective target heating temperatures, the oven enters the temperature-holding stage, indicating that the food ingredients have met the cooking temperature requirements. At this time, to avoid malfunctions caused by the long-term operation of the heating tubes and to improve the steaming and baking efficiency of the steam oven, each heating tube can be controlled to operate alternately at a certain duty cycle within the operation cycle. The duty cycle corresponding to each heating tube can be adjusted using the temperature PID algorithm to maintain the heating temperature of the food ingredients. The adjustment process of the specific PID algorithm is prior art and will not be elaborated here.

[0090] Figure 5A and Figure 5B FIGS. and

[0090] are schematic diagrams of two specific cooking processes of the cooking device. Exemplarily, when the steam oven executes the temperature-rising stage, the adjustment stage, and the temperature-holding stage, the steam oven controls the top heating tubes (9, 34), the back heating tubes (16, 18, 20, 23), and the bottom heating tube (21) to work according to different logics based on the differences between the target cooking temperature and the actual temperature detected inside the oven at present (i.e., the actual temperature T_actual of each heating tube) and the different actual positions of the food ingredients:

[0091] 1. Temperature-rising stage

[0092] When T_actual < T M each heating tube operates at full power simultaneously.

[0093] Exit condition: T_actual ≥ T M .

[0094] 2. Adjustment stage

[0095] During the adjustment stage, T_target heating temperature = T M + T N .

[0096] Exit condition: T_actual = T_target heating temperature.

[0097] 3. Temperature-holding stage

[0098] Load action logic: After entering the temperature-holding stage, each heating tube operates alternately at a certain duty cycle (at least one is operating), with a cycle of t, and the cycle duty cycle is determined by the temperature PID control algorithm.

[0099] Exit condition: Exit when the cooking work ends.

[0100] Thus, no matter where the user places the ingredients to be cooked inside the steam oven, precise temperature control can be achieved, making the temperature around the ingredients consistent with the preset temperature and bringing a better user experience. By setting up position detection devices such as cameras or infrared sensors to confirm the specific position of the ingredients inside the oven, a multi-directional and multi-angle heating and temperature detection mechanism can be realized. Then, according to the cooking mode selected by the user and the set parameters, through the detection of multiple temperature sensors and the adjustment of the temperature PID algorithm, multiple heating tubes can be flexibly controlled to turn on or off according to the corresponding duty cycle, enabling it to adapt to different cooking positions. Moreover, its cooking efficiency and temperature control effect will be greatly improved, accurate and stable, which can make the temperature control inside the steam oven more accurate and the cooking effect better.

[0101] By performing the above steps, the heating control method of the cooking device provided by the embodiment of the present invention can accurately control the target heating temperature of each heating tube by using the cooking mode selected by the user, the target cooking temperature, and the position relationship between the ingredients and each heating tube, so as to ensure that the ingredients maintain the target cooking temperature during the cooking process. No matter where the user puts the ingredients into the cooking device, precise temperature control can be achieved, thereby guaranteeing the cooking effect of the ingredients and improving the user experience.
