Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling equipment, and particularly to a control method, device, equipment and medium for a multi-cavity steaming and baking cooking equipment. Background Art

[0002] Currently, the steaming and baking cooking equipment in the prior art is mainly a steam oven, which is widely used in households and professional kitchens. Combining the advantages of two cooking methods of steaming and baking, it can meet various cooking needs. For a steam oven that can implement two cooking methods of steaming and baking in a common cooking cavity, since the cooked foods in each sub-cooking cavity are different, the cooking durations are also different. For example, when cooking simultaneously in multiple sub-cooking cavities, if the cooking durations required for each food are different, taking out the food that has completed cooking first will cause the thermal field of other sub-cooking cavities that are still cooking to lose temperature; if all the cooked foods are taken out after the cavity with the longest cooking time has completed cooking, the food in the cavity with a short cooking time will be overcooked due to the influence of the thermal field of the sub-cooking cavity with a long cooking time nearby. Therefore, there is an urgent need for a control method for a multi-cavity steaming and baking cooking equipment to solve the problem of poor cooking results of foods caused by different food durations in each sub-cooking cavity due to the limitation of the existing cooking method logic in the multi-cavity steaming and baking cooking equipment. Summary of the Invention

[0031] It should be further understood that the term "and / or" used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0032] To solve the problem of poor food cooking results caused by different food cooking durations in each sub-cooking cavity of a multi-cavity steam baking cooking device in the prior art, an embodiment of the present invention provides a control method for a multi-cavity steam baking cooking device, and this method is applied to a multi-cavity steam baking cooking device. Referring to Figures 10 to 12 , the configuration of this device includes a cooking box 1, and a cooking cavity 11 is provided inside the cooking box 1. The cooking cavity 11 is divided into four sub-cooking cavities by a partition assembly 4 composed of a first partition 41 and a second partition 42 that can be combined together vertically and horizontally. A cooking component is provided in each sub-cooking cavity, and these so-called cooking components include a baking heating component 2 for performing baking cooking and a steam generating component 3 for steam cooking. The baking function of the baking heating component 2 is realized by a baking heating tube 21. The steam generating component 3 generates steam through a steam generator 33, and sprays the steam through a connected pipeline to a steam nozzle 31 provided on the inner wall 13 of the cooking cavity 11 into the sub-cooking cavity that needs to perform steam cooking. The water in a water tank 35 provided outside the cooking box 1 is injected into the steam generator 33 through a connected pipeline relying on the power provided by a water pump 34. When the steam pressure in the sub-cooking cavity where steam cooking is performed is too high and steam overflows, it is drawn back by a steam return port 32 provided on the inner wall 13 of the cooking cavity 11, and finally condenses and is conveyed back to the water tank 35 or the steam generator 33 again. Specifically, the heating tube is used to bake food, and the steam generator 33 generates steam and injects it into the cooking cavity 11 to steam food, and the two can perform different cooking operations respectively. When in use, the user puts the ingredients to be cooked into each sub-cooking cavity respectively, and closes the door of the cooking box 1 to make the cooking cavity 11 closed.

[0033] Referring to Figure 1, based on the above multi-cavity steam baking cooking device, the control method of the multi-cavity steam baking cooking device includes:

[0034] S110. When performing multi-cavity cooking, receive the user's selection of cooking modes and parameter settings for each sub-cooking cavity;

[0035] S120. Calculate the theoretical cooking duration of each sub-cooking cavity according to the selected cooking mode and the parameter settings, and determine the longest theoretical cooking duration among them;

[0036] S130. Start the cooking components in the sub-cooking cavity corresponding to the longest cooking duration, and delay starting the cooking components in the sub-cooking cavity with a theoretical cooking duration less than the longest cooking duration;

[0037] S140. When all the sub-cooking cavities have completed cooking, prompt the user to take out the ingredients.

[0038] Refer to Figures 10 to 12, when the user needs to perform multi-cavity cooking, the user can independently select the working modes of each sub-cooking cavity on the control panel 51, such as steaming or grilling, and the corresponding cooking parameters. The specific parameter settings include cooking temperature, cooking time, steam volume, etc. After receiving the cooking mode and parameters set by the user, the control system automatically calculates the theoretical cooking duration required for each sub-cooking cavity. For example, if a sub-cooking cavity is set to the steaming mode, the system will calculate the theoretical cooking duration based on the set steaming temperature and steaming time. The calculation of the theoretical duration converts the user's intuitive setting into a quantifiable time parameter, ensuring the accuracy of subsequent timing control. Through an internal algorithm, the system compares the theoretical cooking durations of each sub-cooking cavity and determines the longest theoretical cooking duration (Tc). Determining the longest duration provides a benchmark for delaying the start of other sub-cavities, avoiding the disruption of the thermal field stability due to taking out items midway. The control system first starts the cooking components in the sub-cooking cavity corresponding to the longest theoretical cooking duration. For example, if the theoretical cooking duration of a certain sub-cooking cavity is 40 minutes, which is the longest among all sub-cooking cavities, the system will first start the cooking components of this sub-cooking cavity. For other sub-cooking cavities with theoretical cooking durations shorter than the longest cooking duration, the system will start them with a delay according to the time difference. For example, if the theoretical cooking duration of another sub-cooking cavity is 30 minutes, the system will start the cooking components of this sub-cooking cavity 10 minutes after the sub-cooking cavity corresponding to the longest theoretical cooking duration is started. Through the above delay start mechanism, the ingredients in each sub-cooking cavity can be cooked at the same time point. By starting at different times, it is avoided that the user opens the cooking box 1 midway to take out the ingredients in the completed sub-cavity, resulting in heat loss in other sub-cavities. In addition, the delayed start of the short-time sub-cavity reduces the ineffective preheating time and lowers the overall energy consumption. Eventually, all ingredients can be cooked to completion in the best state, avoiding overcooking or undercooking. When all sub-cooking cavities have completed cooking, the control system will emit a prompt sound or display information to remind the user to take out the ingredients. The user opens the door of the cooking box 1 according to the prompt sound or display information and takes out the ingredients in each sub-cooking cavity. The unified prompt ensures that the user takes out all the ingredients at one time, reducing the complexity of multiple operations. It also avoids the user forgetting the food in the uncompleted sub-cavity, preventing the risk of food spoilage or equipment idling.

[0039] Through the method of this embodiment, it effectively avoids the uneven cooking effect of food caused by the mismatch of cooking times between different sub-cooking cavities, greatly improving the cooking efficiency and the cooking quality of ingredients. It makes multi-cavity steam and grill cooking equipment such as a split-cavity steam and grill oven more suitable for the multi-task cooking needs of home and commercial kitchens.

[0040] Further, referring to Figure 2 , step S130 includes:

[0041] S131. Record the cooking duration of each sub - cooking cavity whose theoretical cooking duration is less than the longest cooking duration as the synchronous cooking duration;

[0042] S132. Calculate the difference between the longest cooking duration and each synchronous cooking duration, and record it as the delayed cooking start time;

[0043] S133. Start the cooking component corresponding to the sub - cooking cavity according to the longest cooking duration, and cook according to the corresponding cooking mode;

[0044] S134. Delay the start of the cooking components of each corresponding sub - cooking cavity according to each of the delayed cooking start times, and cook according to the corresponding cooking mode until the timing of the longest cooking duration ends.

[0045] The control system compares the theoretical cooking durations of each sub - cooking cavity to determine the longest cooking duration Tc. According to the difference between the longest cooking duration Tc and each synchronous cooking duration Ta, the control system calculates the delayed cooking start time Tx for each sub - cooking cavity. For example, if the theoretical duration of sub - cooking cavity A (grilling steak) is 40 minutes and that of sub - cooking cavity B (steaming fish) is 25 minutes, then the synchronous cooking duration of sub - cavity B is 25 minutes. The controller calculates the delayed cooking start time for each sub - cavity according to the following formula: Delayed cooking start time Tx (15 minutes)=Longest cooking duration Tc (40 minutes)-Synchronous cooking duration Ta (25 minutes). The control system thus obtains the delayed cooking start time for each sub - cooking cavity. In actual operation, the control system first starts the cooking component of the sub - cooking cavity corresponding to the longest cooking duration, that is, sub - cooking cavity A starts cooking according to the preset cooking mode. After this sub - cooking cavity is started, the control system delays the start of the cooking components of other sub - cooking cavities according to the previously calculated delayed cooking start times. For example, when sub - cooking cavity A has been started for 15 minutes, the control system will start sub - cooking cavity B so that it starts cooking according to the preset cooking mode. During the 15 - minute period when sub - cooking cavity A is started, sub - cooking cavity B is in the pre - heating state. When this cavity starts cooking, a certain pre - heating time can be saved, making the food cooking time shorter. The method of this embodiment effectively coordinates the working times of the multi - cavity steaming and baking cooking device through the calculation and delayed start mechanism, ensuring that the ingredients under different cooking modes can be cooked simultaneously, greatly improving the cooking efficiency and the cooking quality of the ingredients, and meeting the diverse cooking needs of users.

[0046] In addition, a dynamic calibration mechanism is also set in the system to cope with the interference in actual cooking. In actual use, it will obtain the actual temperature change through the temperature sensors 15 set in each sub - cooking cavity, so as to fine - tune the cooking temperature and cooking duration according to the expected results of the cooking program preset by the user, ensuring that all sub - cavities are finally synchronized to complete.

[0047] Further, referring to Figures 10 to 12 , the cooking assembly of the multi-cavity steam baking cooking device includes a baking heating tube 21 and a steam generator 33, and the baking heating tube 21 and the steam generator 33 are arranged on the inner wall 13 of the sub-cooking cavity. Referring to Figure 3 , the step of "cooking according to the corresponding cooking mode" in step S134 includes:

[0048] S1341. If the baking mode is selected for the sub-cooking cavity, control the corresponding baking heating tube to work according to the parameter setting;

[0049] S1342. If the steaming mode is selected for the sub-cooking cavity, control the steam generator 33 to generate steam according to the parameter setting.

[0050] In the multi-cavity steam baking cooking device of this embodiment, the baking heating tube 21 is usually arranged at the top of the sub-cooking cavity, and is used to radiate heat to achieve dry-heat cooking modes such as baking and air frying. The steam generator 33 is usually arranged below the side of the sub-cooking cavity, and evenly diffuses the steam into the cavity through the steam guide pipe to achieve wet-heat cooking modes such as steaming and stewing. Specifically, when the user selects the baking mode, the control system will start the baking heating tube 21 of the corresponding sub-cooking cavity. The control system will adjust the working state of the baking heating tube 21 according to the cooking parameters preset by the user, such as baking temperature and time. The baking heating tube 21 will quickly heat up to the set temperature and maintain a stable heat output throughout the cooking process, so as to ensure that the ingredients can be evenly baked in a high-temperature environment and achieve an ideal color and texture. When the user selects the steaming mode, the control system will activate the steam generator 33 of the corresponding sub-cooking cavity. The steam generator 33 will generate steam according to the preset cooking parameters, such as the amount of steam and time, to ensure that the steam is evenly distributed in the sub-cooking cavity. The steam can quickly transfer heat, enabling the ingredients to be cooked in a moist environment, retaining more nutrients and moisture, and thus achieving a healthy cooking effect. During the actual operation process, the control system first receives the cooking mode selection and parameter setting of each sub-cooking cavity by the user. Subsequently, the control system sequentially starts the corresponding baking heating tube 21 or steam generator 33. For the sub-cooking cavity selected for the baking mode, the control system will control the working state of the baking heating tube 21 according to the set parameters, and monitor and adjust the temperature in real time during the cooking process, and maintain the cavity temperature stability through the PID algorithm to ensure the baking effect. For the sub-cooking cavity selected for the steaming mode, the control system will control the steam output of the steam generator 33 to ensure that the amount of steam and time meet the set requirements, and drain water periodically to prevent the condensed water from diluting the steam and ensure the heat conduction efficiency. In this way, the multi-cavity steam baking cooking device can flexibly perform steaming and baking operations simultaneously in different sub-cooking cavities to meet the diverse cooking needs of users. At the same time, the precise control and real-time adjustment functions of the control system ensure that the cooking effect of the ingredients in each sub-cooking cavity reaches the best, thereby improving the overall cooking efficiency and quality.

[0051] Further, referring to Figures 10 to 12 , the multi-cavity steam baking cooking device further includes a water tank 35 and a water pump 34. The water tank 35 and the water pump 34 are arranged outside the cooking box 1. The water pump 34 is connected to the water tank 35 and the steam generator 33, and a liquid level sensor is further arranged in the water tank 35. Referring to Figure 4 , the steps of S1342 include:

[0052] S13421. If the sub-cooking cavity selects the steaming mode, detect whether there is water in the water tank through the liquid level sensor;

[0053] S13422a. If there is water in the water tank, the water pump pumps a preset amount of water from the water tank to the steam generator according to the parameter setting;

[0054] S13423. The steam generator vaporizes the preset amount of water into steam and inputs it into the corresponding sub-cooking cavity.

[0055] Refer to Figures 10 to 12 , the water tank 35 and the water pump 34 are integrated outside the cooking box 1 of the steam cooking device and are connected to the steam generators 33 of each sub-cooking cavity through a water pipe. In a specific product, in order to ensure the stability of the equipment's center of gravity, they are usually located at the back or bottom of the equipment. A liquid level sensor is installed in the water tank 35, which can be a float type or a capacitive sensor to monitor the remaining water volume in real time. The water pump 34 usually uses a micro centrifugal pump or a diaphragm pump, and its flow rate is controlled by the controller's pulse width modulation signal. The water pump 34 is connected to the steam generators 33 of each sub-cavity through a shunt solenoid valve to achieve independent water supply for each cavity. The liquid level sensor outputs a signal to the controller, and when the water level is lower than the safety threshold, a water shortage alarm is triggered. By monitoring the water volume in real time through the liquid level sensor, it is avoided that the steam generator 33 runs idly in a waterless state and causes dry burning damage. If the liquid level sensor detects that there is water in the water tank 35, the control system will start the water pump 34 and pump a preset amount of water from the water tank 35 to the steam generator 33 according to the preset cooking parameters, such as the steam volume and duration. For example, if the user sets the steaming time to 20 minutes and the required steam volume is 500 milliliters, the control system will instruct the water pump 34 to pump 500 milliliters of water into the steam generator 33. After receiving the preset amount of water, the steam generator 33 quickly heats and vaporizes the water through an internal heating device. For example, after receiving the preset water volume, the steam generator 33 starts an electric heating plate or a high-frequency induction coil for heating to heat the water to the boiling point and vaporize it. The steam is input into the sub-cooking cavity through the diffusion holes on the side wall of the cavity via the steam pipe connecting the steam generator 33. At the same time, the humidity sensor in the cavity feeds back data in real time, and the controller adjusts the heating power of the steam generator 33 accordingly to maintain the set humidity. The steam generator 33 will accurately control the generation speed and amount of steam according to the set and feedback parameters to ensure that the steam can be evenly and continuously input into the corresponding sub-cooking cavity, thereby providing a stable high-temperature and humid environment for the food ingredients.

[0056] In addition, for the steaming sub-cavity that needs to be started with a delay, during the delay waiting period, if other sub-cavities start the steaming mode, the controller checks whether the remaining water volume meets the subsequent requirements, and if it is insufficient, it prompts the user to replenish water in advance. For the steaming sub-cavity that needs to be started with a delay, the water pump 34 of it is started 10 seconds before the end of the delay countdown, and the calculated water volume is pre-delivered to the corresponding steam generator 33 to ensure that it is immediately vaporized when the countdown reaches zero, eliminating the delay in steam generation and ensuring that the steaming program of the delayed sub-cavity is strictly aligned with the theoretical duration.

[0057] Furthermore, refer toFigures 10 to 12 , the multi-cavity steam cooking device further includes an alarm component 52. Refer to Figure 5 , the steps of S1342 further include:

[0058] S13422b. If the water tank is short of water, alarm the user to add water to the water tank through the alarm component.

[0059] The alarm component 52 is set according to specific circumstances and is usually set outside the cooking chamber 1. The alarm component 52 can be a sound alarm, a visual warning light, or a prompt message on the liquid crystal display screen of the control panel 51, which is used to issue an alarm when the water tank 35 is short of water to remind the user to add water in time. When the user selects the steaming mode of a certain sub-cooking cavity, the control system first detects the water level in the water tank 35 through the liquid level sensor. If the liquid level sensor detects that the water level in the water tank 35 is lower than the preset safety line, the control system will issue an alarm through the alarm component 52. For example, if the liquid level sensor detects that the amount of water in the water tank 35 is not enough to complete the preset steaming task, the alarm component 52 will be activated immediately.

[0060] Specifically, the alarm component 52 can remind the user in various ways. For example, for sound alarm, the sound alarm inside the device emits a beeping sound to remind the user that the water tank 35 is short of water. The frequency and volume of the beeping sound can be adjusted according to actual needs to ensure that the user can hear the alarm in time. Another example is visual warning, the indicator light on the device flashes or changes color, or the prompt message "Water shortage, please add water" is displayed on the liquid crystal display screen. This visual warning can be directly seen by the user when viewing the device. Another example is remote notification. When the device supports the networking function and can be interconnected into the smart home system, the alarm information can be sent to the user's mobile device through the mobile application or other remote control systems, which is convenient for the user to know the status of the device in time from a distance. Once the user receives the alarm information, they need to add water to the water tank 35 as soon as possible. After adding water, the liquid level sensor will re-detect the water level in the water tank 35. If the water level returns above the safety line, the alarm component 52 will automatically stop alarming, and the control system will continue to control the water pump 34 to deliver an appropriate amount of water to the steam generator 33 according to the preset parameters. Through the above control method, it can effectively prevent the steam generator 33 from dry burning in the case of water shortage, protect the safety of the device and extend its service life.

[0061] In one embodiment, refer to Figures 10 to 12 , the multi-cavity steam cooking device further includes a door 12, the door 12 is pivotally provided on the cooking chamber 1, and a first microswitch 121 is provided between the door 12 and the cooking chamber 1. Refer to Figure 6 , before S110, it further includes:

[0062] S101. Detect the opening and closing state of the first microswitch;

[0063] S102. When the closing signal of the first microswitch is received, perform a status self-check.

[0064] S103. When the opening signal of the first microswitch is received, stop power supply to the cooking component.

[0065] The door 12 of the multi-cavity steam cooking and baking device is connected to the cooking box 1 through a hinge, and a first microswitch 121 is embedded in the edge of the door frame. The first microswitch 121 can be mechanical or magnetic induction type. When the door 12 is closed, the door body presses the microswitch to trigger a closing signal; when the door is opened, the switch resets and outputs an opening signal. After the user closes the door 12, the controller immediately detects the status of the first microswitch 121. If it is a closing signal, start the status self-check process, which includes power-on testing of the cooking component, sensor calibration, water level detection of the water tank 35, etc. If the self-check passes, the user is allowed to select a mode and set parameters. The self-check process ensures that the device starts only when the door body is fully closed and the status of each component is normal, reducing the risk of failure. During the cooking process, if the door 12 is accidentally opened, that is, the first microswitch 121 is opened, the controller immediately cuts off the power supply to all cooking components, including turning off the heating tube, steam generator 33, and water pump 34. The door-opening power-off mechanism of the multi-cavity steam cooking and baking device is to prevent users from contacting high-temperature steam or heating elements, making its safety protection meet the IEC safety standard.

[0066] In addition, after receiving the opening signal of the door 12, the control system will also visually or audibly prompt the user that the door 12 has been opened and remind the user to close the door 12 to continue the operation. For example, a prompt message "Please close the door 12 to continue the operation" will be displayed on the display screen, and at the same time, a beeping sound will be emitted to remind the user. When the user closes the door 12 again and the first microswitch 121 is closed again, the control system will receive the closing signal again. At this time, the system will perform a status self-check again. After confirming that all parameters and the device status are normal, it will continue to operate according to the selected cooking mode and set parameters by the user, resuming the normal cooking process.

[0067] Further, referring to Figures 10 to 12 , the multi-cavity steam cooking and baking device further includes a partition component 4. A main cooking cavity is provided in the cooking box 1. The partition component 4 is detachably provided in the main cooking cavity 11. The partition component 4 divides the main cooking cavity 11 into at least two cooking cavities 11. When the partition component 4 is provided in the main cooking cavity 11, a second microswitch 16 is provided between the partition component 4 and the inner wall 13 of the main cooking cavity 11. Referring to Figure 7 , the steps of S102 include:

[0068] S1021. When the opening signal of the first microswitch is received, judge the opening and closing state of the second microswitch.

[0069] S1022. When the second micro switch is closed, it is determined that multi-cavity cooking is performed;

[0070] S1023. When the second micro switch is opened, it is determined that single-cavity cooking is performed.

[0071] The partition assembly 4 is composed of a high-temperature resistant metal frame and a heat insulation board, and buckle structures are arranged on both sides thereof to match the installation grooves 14 on the inner wall 13 of the main cooking cavity 11. When the partition is completely inserted into the installation groove 14, the edge of the partition presses the second micro switch 16 at the end of the bottom sliding groove of the installation groove 14, triggering a closing signal. That is, when the first micro switch 121 is closed, the controller synchronously detects the state of the second micro switch 16. If the second switch is closed, it is determined as the multi-cavity cooking mode, and the sub-cavity independent control interface is enabled, allowing the user to set parameters for each sub-cavity separately; if the second switch is opened, it is determined as the single-cavity mode, the sub-cavity setting function is disabled, and the cooking components of the entire main cavity are controlled uniformly. During the cooking process, if the partition is pulled out, that is, the second switch is opened, the controller detects in real time and switches to the single-cavity mode, terminating the original multi-cavity timing control logic. Through this mode of automatically identifying the physical state of the partition, the user does not need to manually switch the setting function mode, avoiding human errors.

[0072] Further, if the second micro switch 16 is closed, it will additionally detect whether the independent sensors of each sub-cavity are online; if the second switch is opened, only the main cavity sensor will be detected. During this process, including the self-check process completed when the first micro switch 121 is closed, when any self-check item fails, the controller locks the start function and prompts a specific fault code on the display screen to protect the device and the user, and prompts and guides for maintenance.
