Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to a method, apparatus, steam oven and storage medium for testing the sealing performance of a steam oven. Background Technology

[0002] Steam ovens require high sealing performance during operation. Related technologies primarily focus on improving the sealing performance by adjusting the mechanical structure of the steam oven, such as using mechanical mechanisms to lock the door when closed. However, after prolonged use, wear and tear on some structural components or aging of the sealing strips can cause the oven door to loosen. This allows high-temperature gases inside the cavity to impact the door and escape through the gaps, potentially scalding the user and posing a safety hazard. Summary of the Invention

[0046] The first detection unit is used to determine that the sealing performance of the steam oven does not meet the preset sealing standard when the user feedback information indicates that the candidate parameter information is rejected;

[0062] This application provides a method, apparatus, oven, and storage medium for testing the sealing performance of a steam oven. By responding to a sealing performance test command, the method acquires target calibration parameter information of the steam oven. This target calibration parameter information includes the speed calibration value, torque calibration value, and current calibration value of a fan installed in the steam oven, which circulates the air inside the oven cavity. The method acquires the current operating speed value of the fan. If the absolute value of the difference between the speed value and the speed calibration value is less than or equal to a first threshold, the method acquires the torque and current values ​​of the fan at that speed value. Based on the torque value, torque calibration value, current value, and current calibration value, the sealing performance of the steam oven is determined. Thus, when the fan speed in the steam oven tends to stabilize, the method detects whether the corresponding torque and current of the fan tend to stabilize, accurately measuring the sealing status of the steam oven. This adds a self-testing function to the sealing performance of the steam oven, eliminating the risk of poor sealing and air leakage in older machines that have been used for many years, thereby improving the safety of using the steam oven.

[0073] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely one embodiment of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0074] As used herein, “an embodiment” or “an embodiment” refers to a specific feature, structure or characteristic that may be included in at least one implementation of this application.

[0075] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0076] The following describes in detail, with reference to the accompanying drawings, a method, apparatus, steam oven, and storage medium for testing the airtightness of a steam oven according to an embodiment of this application.

[0077] Figure 1 This is a flowchart illustrating a method for testing the sealing performance of a steam oven, as provided in an embodiment of this application. This method can be implemented using software and / or hardware; please refer to [link / reference]. Figure 1 The method may include:

[0078] S101, in response to the sealing test command, obtains the target calibration parameter information of the steam oven; the target calibration parameter information includes the speed calibration value, torque calibration value and current calibration value of the fan installed in the steam oven, the fan is used to circulate the internal air of the steam oven.

[0079] The steam oven is equipped with a fan that is connected to the oven's interior cavity and circulates the air within the cavity. The target calibration parameters are reference parameters used to indicate the fan's operating parameters during the oven's sealing test. These parameters include the fan's speed, torque, and current calibration values.

[0080] Optionally, the speed rating can be lower than the speed at which the steam oven performs its baking function. For example, if the rated speed of the fan impeller is 500 rpm when the steam oven is operating, the fan speed rating here is 200 rpm. Correspondingly, the torque and current ratings are both related to the speed rating. Specifically, the torque rating refers to the torque value of the fan at that speed rating, and the current rating refers to the conduction current value of the fan at that speed rating.

[0081] In one optional implementation, in response to a sealing test command, acquiring the target calibration parameter information of the steam oven includes:

[0082] Check if the steam oven has entered self-test mode;

[0083] Once the steam oven is confirmed to have entered self-test mode, it responds to the sealing test command and obtains the target calibration parameter information of the steam oven.

[0084] Among them, the target calibration parameter information is any one of the pre-stored set of calibration parameter information or the average of multiple stored sets of calibration parameter information.

[0085] Optionally, the self-test mode can be triggered by the user manually starting the self-test function, or by the self-test program that the steam oven automatically starts after being powered on again.

[0086] To match the sealing test function of the steam oven, a set of speed N0, torque T0, and current I0 can be reserved in the built-in memory of the steam oven as preset calibration values ​​when the steam oven leaves the factory. For example, (N0, T0, I0) can be used as the preset calibration value.

[0087] In the initial state, the built-in memory of the steam oven stores a set of preset calibration values, such as (N0, T0, I0). At this time, the target calibration parameter information is this set of preset calibration values, i.e., (N0, T0, I0). In a non-initial state, the built-in memory of the steam oven can store multiple sets of calibration parameter information, i.e., store no more than M sets of values, where M can be an integer greater than or equal to 2, such as, but not limited to, 3, 4, 5, etc. In this case, the target calibration parameter information can be any of the multiple sets of values ​​stored in the memory. Alternatively, the target calibration parameter information can be the average of the multiple sets of values ​​stored in the memory, i.e., (N0, T0, I0). avg ,T avg ,I avg In this way, by selecting the average value of multiple sets of stored calibration parameter information, not only can detection errors caused by mis-storage be avoided, but also the dispersion of fluctuations in values ​​such as speed, torque, and current can be reduced, improving judgment accuracy, reducing the probability of misjudgment, and thus improving the accuracy of sealing test results.

[0088] In practical applications, before performing a sealing test, it is first checked whether the steam oven has entered self-test mode. Generally, self-test mode and operating mode are mutually exclusive. If it is determined that the user manually activates the self-test function by triggering the relevant button or touchscreen to enter self-test mode, or if it is determined that the steam oven automatically starts its self-test program after being powered on again to trigger self-test mode, then the steam oven is confirmed to be in self-test mode. When the steam oven is confirmed to be in self-test mode, in response to the sealing test command, the target calibration parameter information of the steam oven is retrieved from the memory. This target calibration parameter information can be any pre-stored set of calibration parameter information, or it can be the average of multiple stored sets of calibration parameter information. If it is determined that the steam oven has not entered self-test mode, there is no need to generate a sealing test command, nor is it necessary to perform subsequent sealing test operations.

[0089] S103, obtain the current operating speed of the fan.

[0090] Optionally, the current operating speed of the fan can be obtained based on sensor A, which may be installed in the steam oven to collect the impeller speed value of the fan in real time, such as n1.

[0091] S105, if the absolute value of the difference between the speed value and the speed calibration value is less than or equal to the first threshold, obtain the torque value and current value of the fan at the speed value.

[0092] Optionally, after obtaining the current operating speed of the fan, the absolute value of the difference between the speed value and the speed calibration value can be calculated, and it can be determined whether the absolute value of the difference is less than or equal to a first threshold (e.g., δn). If it is determined that the absolute value of the difference is less than or equal to the first threshold, it is considered that the two are equal or acceptable, and then the torque value and current value of the fan at that speed value are obtained, for example, the torque value T1 and current value I1 at that speed value n1.

[0093] If the absolute value of the difference is greater than the first threshold and the current speed value is less than the speed calibration value, it indicates that the fan is still in the acceleration phase, and the fan continues to acquire the speed value for the next operation. If the absolute value of the difference is greater than the first threshold and the current speed value is greater than the speed calibration value, it indicates that the self-test module is faulty, and the user can be notified that the self-test module is abnormal and the self-test program will be terminated.

[0094] The first threshold δn can be stored in advance in the built-in memory of the steam oven to characterize the absolute value of the allowable difference between the actual speed of the fan and the speed calibration value. The first threshold can be related to the specifications of the steam oven or the specifications of the sensor. This application does not specifically limit the specific value of the first threshold.

[0095] The torque and current values ​​can be obtained by sensors B and C, respectively. Sensors B and C can be installed in the steam oven to collect the torque or conduction current of the fan in the steam oven.

[0096] S107 determines the sealing performance of a steam oven based on torque value, torque rating value, current value, and current rating value.

[0097] Optionally, the sealing performance of the steam oven can be determined based on the absolute value of the difference between the torque value and the torque calibration value, and the absolute value of the difference between the current value and the current calibration value.

[0098] In an alternative implementation, such as Figure 2 As shown, the sealing performance of a steam oven is determined based on its torque value, torque rating, current value, and current rating, including:

[0099] S201, if the absolute value of the difference between the torque value and the torque calibration value is less than or equal to the second threshold, and the absolute value of the difference between the current value and the current calibration value is less than or equal to the third threshold, the sealing performance of the steam oven is determined to meet the preset sealing standard.

[0100] Optionally, the absolute value m of the difference between the torque value and the torque calibration value, and the absolute value n of the difference between the current value and the current calibration value can be calculated first. Then, it can be determined whether the absolute value m of the difference is less than or equal to the second threshold, and whether the absolute value n of the difference is less than or equal to the third threshold. If it is determined that both are less than the corresponding threshold, the sealing performance of the steam oven is determined to meet the preset sealing standard, which means that the sealing performance of the steam oven is good.

[0101] In an optional implementation, determining the sealing performance of the steam oven based on the torque value, torque rating value, current value, and current rating value further includes:

[0102] S203, if the absolute value of the difference between the torque value and the torque calibration value is greater than the second threshold, and / or the absolute value of the difference between the current value and the current calibration value is greater than the third threshold, it is determined that the sealing performance of the steam oven does not meet the preset sealing standard.

[0103] Optionally, it is determined whether the absolute value m of the difference between the torque value and the torque calibration value is less than or equal to the second threshold, and whether the absolute value n of the difference between the current value and the current calibration value is less than or equal to the third threshold. If it is determined that at least one of the two is greater than the corresponding threshold, for example, the absolute value m of the difference is greater than the second threshold and the absolute value n of the difference is less than or equal to the third threshold; or the absolute value m of the difference is less than or equal to the second threshold and the absolute value n of the difference is greater than the third threshold; or the absolute value m of the difference is greater than the second threshold and the absolute value n of the difference is greater than the third threshold, then it is determined that the sealing performance of the steam oven does not meet the preset sealing standard, that is, the sealing performance of the steam oven is abnormal.

[0104] The second threshold δT and the third threshold δI can be stored in advance in the built-in memory of the steam oven. The second threshold δT is used to characterize the absolute value of the allowable difference between the actual torque of the fan and the torque calibration value, and the third threshold δI is used to characterize the absolute value of the allowable difference between the actual conduction current of the fan and the current calibration value. The second threshold and the third threshold can be related to the specifications of the steam oven or the specifications of the corresponding sensor. This application does not specifically limit the specific values ​​of the two.

[0105] In another alternative implementation, such as Figure 3 As shown, judging the sealing performance of a steam oven based on torque value, torque rating value, current value, and current rating value also includes:

[0106] S205, if the absolute value of the difference between the torque value and the torque calibration value is greater than the second threshold, and / or the absolute value of the difference between the current value and the current calibration value is greater than the third threshold, parameter query information is generated; the parameter query information is used to display to the user object to prompt the user object whether it needs to accept candidate parameter information, the candidate parameter information includes the current running speed value, torque value and current value.

[0107] Optionally, if the steam oven has an operating parameter operation function, it determines whether the absolute value m of the difference between the torque value and the torque calibration value is less than or equal to a second threshold, and whether the absolute value n of the difference between the current value and the current calibration value is less than or equal to a third threshold. If it is determined that at least one of them is greater than the corresponding threshold, for example, the absolute value m of the difference is greater than the second threshold, and the absolute value n of the difference is less than or equal to the third threshold; or the absolute value m of the difference is less than or equal to the second threshold, and the absolute value n of the difference is greater than the third threshold; or the absolute value m of the difference is greater than the second threshold, and the absolute value n of the difference is greater than the third threshold, then it is not directly determined that the sealing performance of the steam oven does not meet the preset sealing standard, but a parameter query information is generated.

[0108] Parameter query information is displayed to the user to prompt them whether they wish to receive candidate parameter information. This candidate parameter information includes the currently operating speed, torque, and current values, such as speed n1, torque T1, and current I1. As an example, the parameter query information can be displayed on the oven's screen, asking the user in text format. For example, the parameter query information could be something like, "Do you want to receive the currently running candidate parameter information?" or "Do you want to save the currently running candidate parameter information?"

[0109] S207 determines the sealing performance of the steam oven based on user feedback information regarding parameter queries.

[0110] Optionally, users can perform different actions when querying parameter information, and generate corresponding user feedback information for each different action, based on which the sealing performance of the steam oven is determined.

[0111] In an alternative implementation, such as Figure 4 As shown, based on user feedback regarding parameter queries, the airtightness of the steam oven is determined by:

[0112] S401, Obtain user feedback information regarding parameter query information;

[0113] S403, if the user feedback indicates that the candidate parameter information should be rejected, it is determined that the sealing performance of the steam oven does not meet the preset sealing standard.

[0114] S405, if the user feedback indicates that the candidate parameter information is accepted, the updated calibration parameter information is obtained based on the candidate parameter information and the stored calibration parameter information of each group, and the updated calibration parameter information is used as the target calibration parameter information, and the process returns to the step of obtaining the target calibration parameter information of the steam oven.

[0115] Optionally, user feedback information regarding the query for this parameter is obtained and identified. If the identified user feedback information indicates rejection of the candidate parameter information, it means that the user does not accept the candidate parameter information. Based on the comparison results of the aforementioned torque value and torque calibration value, and current value and current calibration value, it is determined that the sealing performance of the steam oven does not meet the preset sealing standard, that is, an abnormal sealing performance of the steam oven is detected.

[0116] If the user feedback indicates acceptance of the candidate parameter information, it means the user agrees to use the currently running candidate parameter information. Based on this candidate parameter information and the stored calibration parameter information, updated calibration parameter information is obtained. This situation may occur because changes in spatial location may cause a large deviation between the obtained data set and the calibration value. In this case, the data is accepted and stored to be used as a set of data for calculating the new calibration value, thus reducing the deviation in sealing detection caused by environmental changes.

[0117] Furthermore, the updated calibration parameter information is used as the target calibration parameter information, and the process returns to the step of obtaining the target calibration parameter information of the steam oven. This allows for a re-determination of the target calibration parameter information based on the updated information, and subsequently, a re-evaluation of the steam oven's sealing performance based on the newly determined target calibration parameter information. Specifically, the process can return to step S101 and execute step S101 and subsequent steps to re-test the steam oven's sealing performance based on the updated calibration parameter information until the self-test program terminates. The termination condition for this self-test program can be the result of determining the steam oven's sealing performance, reaching an iteration detection number threshold, or an iteration detection duration threshold.

[0118] In one optional implementation, the updated calibration parameter information is obtained based on the candidate parameter information and the stored parameter calibration information, including:

[0119] Retrieve the stored calibration parameter information for each set;

[0120] If the number of parameter groups contained in each group of calibration parameter information is equal to the preset threshold, delete the first group of calibration parameter information stored in each group of calibration parameter information, and calculate the average of the remaining groups of calibration parameter information and candidate parameter information as the updated calibration parameter information.

[0121] If the number of parameter groups contained in each set of calibration parameter information is less than the preset threshold, the mean of each set of calibration parameter information and candidate parameter information is calculated and used as the updated calibration parameter information.

[0122] Optionally, the built-in memory in the steam oven can store no more than M sets of values. If the number of parameter sets contained in each set of stored calibration parameter information is equal to the preset threshold (i.e., the value M), it is necessary to first delete the calibration parameter information of the first set stored in each set of calibration parameter information. That is, after removing the first set of data currently stored, the sequence number of the remaining sets of data is shifted forward by 1 position, and then the candidate parameter information is entered and stored in the memory. That is, the new set of candidate parameter information is stored as the Mth set of data. After that, the mean of each set of stored calibration parameter information is calculated, that is, the mean of the remaining sets of calibration parameter information and candidate parameter information is calculated, which is used as the updated calibration parameter information.

[0123] If the number of parameter groups in each stored set of calibration parameter information is less than the preset threshold (i.e., the M value), then the candidate parameter information is directly entered and stored in the memory. Afterwards, the mean of each stored set of calibration parameter information is calculated, which is also the mean of the remaining sets of calibration parameter information and the candidate parameter information, and this is used as the updated calibration parameter information.

[0124] In one optional implementation, after obtaining user feedback information regarding the parameter query information, the method further includes:

[0125] If user feedback indicates that candidate parameter information should be ignored, the airtightness test of the steam oven will be suspended.

[0126] Optionally, if the user feedback indicates that the candidate parameter information should be ignored, it indicates that the current candidate parameter information is unqualified. For example, the self-test data obtained due to improper operation, such as food in the cavity of the steam oven, or high internal temperature, makes the data unusable. The candidate parameter information is meaningless to enter, and the sealing test of the steam oven can be suspended.

[0127] The above embodiments introduce a parameter query function to obtain feedback on whether the user accepts the candidate parameter information, and redetermine the sealing performance of the steam oven based on the user feedback. This helps to eliminate special cases. For example, if a set of calibration data is entered when the steam oven is manufactured in city A, and the user uses it in cities B or C with large differences in latitude and longitude, or in environments with large differences in atmospheric pressure, the test value may deviate significantly from the calibration value even if the sealing is good, resulting in false detection. By introducing the parameter query function, it is easy to resolve this abnormal factor through manual intervention, thereby improving the accuracy of the sealing performance test of the steam oven.

[0128] In an alternative implementation, the method further includes:

[0129] An alarm is generated if the oven's sealing performance does not meet the preset sealing standard.

[0130] Optionally, if the sealing performance of the steam oven is determined to be inconsistent with the preset sealing standard, an alarm prompt will be generated. The prompt information can be displayed on the display screen of the steam oven to inform the user that the sealing performance of the steam oven is abnormal and needs to be repaired. This will provide timely feedback on the sealing performance test results and remind the user, thereby reducing the safety issues caused by abnormal sealing performance of the steam oven.

[0131] The inventors discovered that a typical steam oven has a main fan mounted at the front and back to circulate hot air within the oven. When the back pressure is constant, the impeller speed is stable, the resistance generated by the impeller rotation is stable (i.e., the load is stable), and the motor output speed and torque are also constant. When the back pressure changes, the impeller speed changes, causing the resistance to change as well, and consequently, the motor speed and torque also change. For a steam oven, when the door is completely closed and the oven is fully sealed, the back pressure is at its maximum, and the motor eventually stabilizes at a lower speed, resulting in system balance. When there is insufficient airtightness, the back pressure decreases, the motor speed increases, and the system stabilizes in another state; the motor speed, current, and torque differ between these two states.

[0132] Based on this, by responding to the sealing test command, the target calibration parameter information of the steam oven is obtained. The target calibration parameter information includes the speed calibration value, torque calibration value, and current calibration value of the fan installed in the steam oven. The fan is used to circulate the air inside the steam oven cavity. The current operating speed value of the fan is obtained. If it is determined that the absolute value of the difference between the speed value and the speed calibration value is less than or equal to a first threshold, the torque value and current value of the fan at the speed value are obtained. Based on the torque value, torque calibration value, current value, and current calibration value, the sealing performance of the steam oven is judged. In this way, when the speed of the fan in the steam oven tends to be stable, it is detected whether the torque and current of the fan at this time tend to be stable, so as to accurately measure the sealing status of the steam oven. This adds a sealing self-test function to the steam oven, which can eliminate the risk of poor sealing and air leakage injury in old machines that have been used for many years, and improve the safety of using the steam oven.

[0133] For ease of understanding of this application, Figure 5 This illustration shows a partial structural diagram of a steam oven provided in this application. Figure 6 The flowchart illustrating the sealing performance testing method for a steam oven provided in this application is shown below. Figure 5 and Figure 6 As shown, the process includes the following:

[0134] 1) Start self-test mode;

[0135] 2) Obtain the current calibration values ​​of speed N, torque T, and current I from the system;

[0136] 3) After a short time t1, the motor speed n of the fan on the front of the steam oven is obtained by sensor A;

[0137] 4) The controller calculates the absolute value of the difference between the current operating speed of the fan and the rated speed, i.e., δn = |nN|, and determines:

[0138] If δn≤δN, it means that the main fan speed has reached the calibrated value, and proceed to the next step;

[0139] If δn > δN and n < N, it means the main fan is still in the acceleration phase, so return to step 3);

[0140] If δn>δN and n>N, it indicates that the self-test module is faulty, proceed to step 11);

[0141] Wherein, δN is the first threshold used to reflect the speed tolerance;

[0142] 5) The torque t and motor current i of the main fan are obtained by sensor B and sensor C respectively at this time;

[0143] 6) The controller calculates the absolute value of the difference between the fan torque at this speed n and the torque rating, i.e., δt = |tT|, and the absolute value of the difference between the fan current at this speed n and the current rating, δi = |iI|. Then, determine:

[0144] If δt≤δT and δi≤δI, it indicates that the self-test is normal, meaning that the steam oven has good sealing performance, and proceed to step 9);

[0145] Wherein, δT is the second threshold used to reflect torque tolerance, and δI is the third threshold used to reflect current tolerance;

[0146] Otherwise, it is considered an abnormal self-test and proceeds to the next step;

[0147] 7) The user interface module prompts the user for operation, offering three options:

[0148] a. If the user chooses to accept the candidate parameter information, proceed to the next step. This is applicable when the obtained data set deviates significantly from the calibration value due to changes in spatial location, etc. In this case, the user chooses to accept the data and use it as a set of data for calculating the calibration value. If this option is selected, the system will continue to accept and store new data until the self-test program terminates.

[0149] b. The user chooses to ignore the candidate parameter information and proceeds to step 12); In this case, the self-test data obtained due to improper operation, such as food in the container or high internal temperature, is unqualified and the data is meaningless.

[0150] c) If the user chooses not to accept the candidate parameter information, proceed to step 10); that is, if neither of the above two situations applies, it is determined that the equipment sealing performance is damaged and needs to be repaired.

[0151] 8) The system performs data storage operation to store the candidate parameter information, returns to step 2), and recalculates the updated calibration parameter information (N', T', and I'), and continues to perform the sealing test based on the updated calibration parameter information;

[0152] 9) Interface prompt: The sealing performance is good, proceed to step 12);

[0153] 10) Interface prompt: Abnormal sealing performance, proceed to step 12);

[0154] 11) Interface notification: Self-test module malfunction, proceed to step 12);

[0155] 12) The self-test procedure terminates.
