Abstract
Description
Technical Field
[0001] The present disclosure generally relates to the field of household appliances, specifically to the field of kitchen utensils, and particularly to a method, device, and medium for detecting blockages in a cooking device. Background Art
[0002] Currently, people can obtain polished rice and rice flour in the following three ways. The first way is to perform multiple milling processes on paddy rice using a rice milling device. The second way is to process the finished rice using a polished rice device. The third way is to perform multiple milling processes on paddy rice using the milling module of an electric rice cooker, or to perform multiple milling processes on the finished rice using the polished rice module of an electric rice cooker. That is, after the above rice milling devices, polished rice devices, the polished rice module of the electric rice cooker, or the milling module of the electric rice cooker perform milling processes on the finished rice or paddy rice, polished rice and rice flour can be obtained.
[0003] In the prior art, in the first or second way of obtaining polished rice and rice flour, purchasing a rice milling device or a polished rice device will increase the cost of obtaining polished rice and rice flour, and placing the above devices will occupy a large amount of space, and using the above devices has cumbersome operation steps. In the third or fourth way of obtaining polished rice and rice flour, as the number of times of the polished rice module and the milling module of the electric rice cooker increases, the above two modules of the electric rice cooker will become blocked. For example, the rice sieve of the electric rice cooker is filled with broken rice. The blockage will cause the weight of the polished rice or rice flour obtained from the same weight of finished rice or paddy rice to be greatly reduced. That is, the blockage will result in a low efficiency of obtaining polished rice and rice flour. And if the electric rice cooker works in a blocked mode for a long time, the electric rice cooker will be damaged, forcing people to buy a new electric rice cooker. That is, the blockage increases the cost of obtaining polished rice and rice flour.
[0004] In summary, when the rice sieve of the electric rice cooker becomes blocked, it will seriously affect the use of the electric rice cooker. Therefore, there is an urgent need for a solution to detect blockages in the electric rice cooker. Summary of the Invention
[0005] Based on this, it is necessary to provide a method, device, and medium for detecting blockages in a cooking device to solve the above technical problems. By using the method of the present application, blockage detection can be performed on the cooking device, thereby avoiding the situation where the electric rice cooker cannot be used normally due to blockage of the rice sieve.

[0008] If any of the multiple weight values is less than the first weight threshold, it is determined that the sieve of the cooking device is blocked; in the surface removal process, the first weight threshold is used to represent the ideal weight value of the first material or the second material in the measurement cycle when the sieve is not blocked.
[0009] In a second aspect, a clogging detection device for a cooking device is provided, and the device includes:

[0017] In the prior art, when the rice sieve of an electric rice cooker becomes blocked, the use of the electric rice cooker will be seriously affected. Therefore, there is an urgent need for a solution to detect blockages in the electric rice cooker.
[0018] In the prior art, before cooking materials (such as rice), the cooking device can also perform surface removal treatment on the rice (such as wax removal, powder removal, etc. pre-processing), and further separate intermediate products through a sieve to obtain polished rice and rice flour. Heating the polished rice can obtain food with a better taste. However, in the above process, the rice flour is very likely to cause blockage of the sieve, which will also affect the use of the electric rice cooker and pose certain safety hazards. By using the method of this application, blockage detection can be performed on the cooking device, thereby avoiding the situation where the electric rice cooker cannot be used normally due to sieve blockage, and also avoiding the safety hazards brought about by this.

The blockage situation of the sieve can be detected in a timely manner for corresponding treatment to ensure the normal use of the electric rice cooker. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application will be further described in detail below in conjunction with the embodiments and the drawings. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.
[0031] It should be noted that, without conflict, the embodiments in the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0032] In the prior art, in the third or fourth method for obtaining polished rice and rice flour, as the number of times of the polished rice module and the rice milling module of the rice cooker increases, the above two modules of the rice cooker will become blocked. For example, the rice sieve of the rice cooker is filled with broken rice. The blockage will cause the weight of the polished rice or rice flour obtained from the same weight of finished rice or paddy to be greatly reduced. That is, the blockage will result in a low efficiency of obtaining polished rice and rice flour. Moreover, if the rice cooker works in a blocked mode for a long time, the rice cooker will be damaged, forcing people to buy a new rice cooker. That is, the blockage increases the cost of obtaining polished rice and rice flour.
[0033] In summary, when the rice sieve of the rice cooker is blocked, it will seriously affect the use of the rice cooker. Therefore, a solution for detecting the blockage of the rice cooker is urgently needed.
[0034] The blockage detection method for the cooking device provided by the present application can detect the blockage of the cooking device, thereby avoiding the situation where the rice cooker cannot be used normally due to the blockage of the rice sieve. Specifically, the blockage detection method for the cooking device provided by the present application can be applied to a cooking device as Figure 1 shown. Referring to Figure 1 , the cooking device includes a rice processing module 10, a rice conveying module 20, and a rice cooking module 30.
[0035] Among them, the rice processing module 10 includes a cleaning component 1011, a processing part 1012, a feeding port 1013, a polished rice cavity 1014, a baffle 1015, and a powder collection cavity 1016.
[0036] It should be noted that the processing part 1012 is used to process the materials in the polished rice cavity 1014, including but not limited to surface removal treatment. The processing part 1012 stirs the materials in the polished rice cavity to perform surface removal treatment on the materials. For example, the processing part 1012 can polish, roll, peel, and crush the food materials in the polished rice cavity 1014. Specifically, it can be achieved by adjusting the rotation speed, time, strength, etc. of the processing part 1012.
[0037] The processing part 1012 can polish, roll, peel, and crush bean food materials such as rice, paddy, corn, soybeans, and black beans, thereby changing the taste of the food materials and meeting the different eating needs of users. For example, the processing part 1012 can perform extrusion, grinding, or abrasion on paddy, brown rice, etc., so that the husks and edible wax on their outer surfaces are separated, turning paddy and brown rice into white rice, and at the same time forming powdery food materials (generally in the form of bran).
[0038] In addition, when white rice is exposed to the air for a long time, dust and other particles may adhere to the surface of the white rice. At the same time, the surface layer of white rice is easily oxidized, and the impurities on the surface layer of white rice will affect the taste of white rice. The processing part 1012 can also perform extrusion, grinding, or abrasion on rice, etc., to remove the dust and oxide layer on the surface of white rice, and then polish the white rice into shiny rice grains (polished rice), while generating rice flour.
[0039] The polished rice cavity 1014 is in a funnel structure. A baffle 1015 is provided in the middle of the polished rice cavity 1014. The opening or closing of the baffle 1015 can control whether to transfer the polished rice to the polished rice feeding cavity 2012. In addition, the lower part of the polished rice cavity 1014 is a hollow structure, and this hollow structure can be a sieve. The sieve can be used to separate solid rice grains (such as polished rice or broken rice) and powdery particles (such as rice flour). The cleaning component 1011 can perform self-cleaning treatment on the sieve. For example, when the sieve is blocked, the cleaning component 1011 can be used to clean the sieve, timely clean the through holes of the sieve, and ensure the separation effect of the sieve. Among them, the cleaning component 1011 can be a cleaning fan. Starting the cleaning fan can use the blowing effect of the fan to clean the sieve.
[0040] The rice transmission module 20 includes a gravity sensor 2011, a polished rice feeding cavity 2012, a rice inlet 2013, a rice flour feeding cavity 2014, a powder inlet 2015, a baffle 2016, a rice inlet 2017, a baffle 2018, and a powder inlet 2019.
[0041] It should be noted that the gravity sensor 2011 is used to weigh polished rice or rice flour, and can be set at the bottom of the powder collection chamber 1016 for weighing rice flour, or at the bottom of the rice flour feeding chamber 2014 for weighing rice flour, and at the bottom of the polished rice feeding chamber 2012 for weighing polished rice. The specific installation position of the gravity sensor in the embodiments of the present application is not limited and can be set according to actual situations.
[0042] The rice cooking module 30 includes an inner pot 3011, a cooking chamber 3012, and a heater 3013.
[0043] In a specific implementation, finished rice or paddy can enter the polished rice chamber 1014 through the feeding port 1013 and land in the middle of the polished rice chamber, that is, on the upper surface of the baffle 1015. Further, the workpiece 1012 can perform surface removal treatment on the finished rice or paddy, and polished rice and rice flour can be generated during the treatment process. The rice flour can fall into the powder collection chamber 1016 through the hollow structure (such as a sieve) of the polished rice chamber 1014. Secondly, the rice flour can enter the rice flour feeding chamber 2014 through the transmission pipeline of the rice transmission module 20. When the baffle 1015 is opened, the polished rice can enter the polished rice feeding chamber 2012 through the transmission pipeline of the rice transmission module 20. Finally, when the baffle 2016 is opened, the polished rice can enter the cooking chamber 3012, or when the baffle 2018 is opened, the rice flour can enter the cooking chamber 3012, and then the heater 3013 can heat the polished rice or rice flour to obtain steamed rice or rice paste / rice porridge.
[0044] The foregoing Figure 1 introduced the application scenario diagram of the present application. In another embodiment of the present application, a method for detecting blockage of a cooking device is further provided, and this method can be applied to Figure 1 the application scenario shown, and is executed by the cooking device. Figure 2 is the flowchart of this method. Specifically, reference can be made to Figure 2 and this method includes the following steps:
[0045] Step 201: Obtain multiple weight values during the surface removal treatment of the object to be processed; the multiple weight values correspond to multiple measurement periods, and the weight value is the weight value of the first material or the second material in the cooking device during the measurement period.
[0046] Among them, the object to be processed is used to represent the agricultural product to be processed. For example, it can be the finished rice sold in the market, or the rice harvested in the farmland. The surface removal treatment is a treatment that does not change the overall shape of the object to be processed but only removes the surface layer of the object to be processed. For example, rice milling treatment, polished rice treatment, etc. The first material or the second material is the intermediate obtained by separating through a sieve during the surface removal treatment of the object to be processed by the cooking device. For example, when removing the rice flour adhering to the surface of the rice in the rice processing cavity of the cooking device and then separating it using a sieve, polished rice and rice flour can be obtained.
[0047] In a possible implementation manner, during the surface removal process of the object to be processed, if the sieve in the polished rice cavity becomes blocked, it will affect the weight of the produced polished rice or rice flour. Therefore, it is possible to judge whether the sieve is blocked according to the weight of the polished rice or rice flour. Specifically, the weight of the first material or the second material generated during the surface treatment of the material can be obtained periodically, and it is judged whether the sieve is blocked according to the weight value of the material detected in each measurement period. Among them, the measurement period is used to represent the time interval between two consecutive weighings of the first material or the second material. For example, the time interval can be the time difference △t1 between the first weighing time T1 of the first material and the weighing time T0 of the first material before the surface treatment, or the time difference △t1 between the first weighing time T1 of the second material and the weighing time T0 of the second material before the surface treatment. Exemplarily, the time difference △t1 can be 1 min. That is, during the surface removal treatment process, the first material or the second material can be weighed every 1 min to obtain the weight difference △1 of the first material at an interval of 1 min, or the weight difference △1' of the second material at an interval of 1 min.
[0048] Exemplarily, the weight value of the material within a measurement period is the weight of the actually produced material within that measurement period. During the surface removal treatment of the object to be processed, the rice flour in the powder collection cavity 1016 and the polished rice in the polished rice cavity 1014 are not cleaned. The weight of the rice flour in the powder collection cavity 1016 and the weight of the polished rice in the polished rice cavity 1014 accumulate over time. Therefore, the weight value of the material in the current measurement period can be obtained according to the weight value measured in the current period and the weight value measured in the previous period. For example, the difference between the weight value of the first material measured in the current period and the weight value of the first material measured in the previous period is the weight value of the first material corresponding to the current period, or the difference between the weight value of the second material measured in the current period and the weight value of the second material measured in the previous period is the weight value of the second material corresponding to the current measurement period.
[0049] In a specific implementation, when the time of the surface removal process reaches the first measurement period T1, the weight value can be the difference between the weight value of the first material measured at the first measurement period T1, which is 79 g, and the weight value of the first material measured before processing, which is 0 g. For example, △1 is 79 g. Or, when the time of the surface removal process reaches the first measurement period T1, the weight value can be the difference between the weight value of the second material measured at the first measurement period T1, which is 10 g, and the weight value of the second material measured before processing, which is 0 g. For example, △1’ is 10 g. Or, when the time of the surface removal process reaches the second measurement period T2, the weight value corresponding to the measurement period T2 can be the difference between the weight value of the first material measured at the second measurement period T2, which is 150 g, and the weight value of the first material measured at the measurement period T1, which is 79 g. For example, △2 is 71 g. Or, when the time of the surface removal process reaches the second measurement period T2, the weight value corresponding to the measurement period T2 can be the difference between the weight value of the second material measured at the second measurement period T2, which is 21 g, and the weight value of the second material measured at the measurement period T1, which is 10 g. For example, △2’ is 11 g.
[0050] Step 202: If there are multiple weight values less than the first weight threshold, it is determined that the screen of the cooking device is blocked.
[0051] Among them, the first weight threshold is used to represent the ideal weight value of the first material or the second material within one measurement period when the screen is not blocked, and can be the lower limit of the weight of the first material or the second material (such as polished rice or rice flour) added within one measurement period in the normal working state of the rice processing module 10. When the screen is blocked, the weight of the first material or the second material generated within one measurement period decreases and may be less than the above first weight threshold. Therefore, when there is a weight value less than the first weight threshold among the weight values of multiple measurement periods, it is determined that the screen is blocked.
[0052] Exemplarily, before the rice processing module 10 performs the surface removal process on the material, the weight value of the first material is 0 g. After starting to execute the surface removal process, when the processing time reaches the first period T1 of 1 min, the weight value of the first material is 79 g, then the first weight value △1 is 79 g; when the processing time reaches the second period T2 of 2 min, the weight value of the first material is 150 g, and the weight value corresponding to the period T2 is 71 g (150 g - 79 g); when the processing time reaches the third period T3 of 3 min, the weight value of the first material is 190 g, and the weight value corresponding to the period T3 is 40 g (190 g - 50 g); when the processing time reaches the fourth period T4 of 4 min, the weight value of the first material is 220 g, and the weight value corresponding to the period T4 is 30 g (220 g - 190 g);
[0053] That is to say, through step 101, the weight values of four consecutive cycles T1 to T4 can be obtained as (79g, 71g, 40g, 30g) respectively. In the method provided by the embodiments of the present application, when the weight value of the first material or the weight value of the second material obtained in consecutive measurement cycles is less than the first weight threshold, it is determined that the sieve is blocked. Assuming that the first weight threshold △1 is 65g, when the weight value of 40g is obtained in cycle T3, it can be determined that the sieve is blocked. Alternatively, if the weight values of the first material or the weight values of the second material obtained in N consecutive measurement cycles are all less than the first weight threshold, it can be more accurately determined that the sieve is blocked. For example, N can be taken as 3.
[0054] In the prior art, before cooking materials (such as rice), cooking equipment can also perform surface removal treatment on the rice (such as wax removal, powder removal, etc. pre-processing), and further separate intermediate products through a sieve to obtain polished rice and rice flour. Heating the polished rice can obtain food with better taste. However, in the above process, the rice flour is very likely to cause the sieve to be blocked, which will also affect the use of the rice cooker and pose certain safety hazards. By using the method of the present application, the cooking equipment can be detected for blockage, so as to avoid the situation that the rice cooker cannot be used normally due to the blockage of the rice sieve, and can also avoid the safety hazards caused thereby. Specifically, when the sieve is not blocked, the weight of the intermediate product generated during the surface removal treatment of the material is approximately constant. The embodiments of the present application can periodically weigh the weight of the intermediate product generated during the processing of the material, and judge whether the sieve is blocked according to the change in the weight of the intermediate product (for example, whether the weight value is less than a preset weight threshold). The blockage condition of the sieve can be detected in time for corresponding treatment to ensure the normal use of the rice cooker.
[0055] In another embodiment of the present application, after determining that the sieve of the cooking equipment is blocked according to the first weight threshold, the blockage degree of the sieve can also be judged according to the second weight threshold, so as to perform different cleaning methods according to the blockage degree of the sieve. Among them, the second weight threshold can be the lower limit value of the material weight that ensures the normal execution of the above surface removal treatment. It can be judged the blockage degree of the sieve according to whether there is at least one target weight value less than the second weight threshold among the multiple weight values, so as to perform the cleaning treatment of the sieve.
[0056] In a possible implementation, when the weight of the first material or the second material generated within a measurement period is small enough, even less than the second weight threshold, on the one hand, it indicates that the sieve has been severely blocked, and on the other hand, the surface removal process of the rice processing module 10 can be stopped to avoid damaging the rice processing drive component. For example, the agitation of the processing component 1012 can be stopped; in addition, when the rice processing module 10 stops working, a prompt message can be output through the prompt component of the cooking device, and the prompt message is used to instruct the user to clean the sieve of the cooking device. The prompt message includes at least one of voice information and text information. The prompt component can be the display component of the cooking device or the audio playback component of the cooking device. For example, the cooking device can output a voice as follows: The rice sieve is blocked. Please enable the cleaning component in time for cleaning. For another example, the cooking device can display text as follows: The rice sieve is blocked. Please clean it in time.
[0057] That is to say, if there is at least one target weight value less than the second weight threshold among the multiple weight values corresponding to the above multiple measurement periods, the surface removal process of the object to be processed is stopped, and a prompt message is output.
[0058] In another possible embodiment, if there is no at least one target weight value less than the second weight threshold among the multiple weight values corresponding to the above multiple measurement periods, the surface removal process of the object to be processed is continued, and the sieve is self-cleaned.
[0059] It can be understood that when the weight of the first material or the second material generated within a measurement period is less than the first weight threshold but greater than the second weight threshold, it indicates that although the sieve is blocked, the normal operation of the rice processing module can still be ensured. Then, the surface removal process of the rice processing module 10 can be maintained. In addition, the sieve is self-cleaned to timely handle the blockage problem of the sieve.
[0060] Exemplarily, the self-cleaning process of the sieve can be to control the cleaning component 1011 to clean the hollow structure (i.e., the sieve) at the lower part of the polished rice cavity 1014. For example, the cleaning component 1011 can be a blower, and the cooking device can control the blower to blow air towards the sieve, so that the powdery substances blocking the through holes of the sieve fall off, realizing the cleaning of the sieve and improving the filtering and separation effect of the sieve.
[0061] In another possible embodiment, if there is at least one target weight value less than the second weight threshold among the multiple weight values corresponding to the multiple measurement cycles, the clogging degree of the screen can be determined according to the target weight value among the multiple weight values, and a screen cleaning procedure matching the clogging degree is executed. Among them, the cleaning degrees of different screen cleaning procedures are different. When the cleaning component 1011 is a blower, the wind force of the blower is different under different screen cleaning procedures to achieve different cleaning degrees.
[0062] Specifically, the clogging degree of the screen can be determined according to the quantity ratio of the target weight value to the multiple weight values. For example, referring to the example described above, during the surface removal process of the workpiece to be processed, the weight values of four consecutive cycles T1 to T4 can be obtained as (79g, 71g, 40g, 30g). Assume that the first weight threshold is 65g and the second weight threshold is 45g. If there are weight values less than 65g among the four weight values 79g, 71g, 40g, 30g, it indicates that the screen is clogged. Further, among the four weight values 79g, 71g, 40g, 30g, there are weight values (40g, 30g) less than the second weight threshold of 45g. Then, the clogging degree of the screen is determined according to the quantity ratio of the target weight values (40g, 30g) to (79g, 71g, 40g, 30g). For example, the number of target weight values less than the second weight threshold is 2, and the weight values obtained from consecutive measurement cycles are 4. Then the proportion of the target weight value (i.e., the above quantity ratio) is 50%. Assume that the proportion of the number of target weight values is less than the first ratio of 10%, then the clogging degree of the screen is a third-level clogging; if the proportion of the number of target weight values is greater than the first ratio of 10% and less than the second ratio of 30%, then the clogging degree of the screen is a second-level clogging; if the proportion of the number of target weight values is greater than the second ratio of 30%, then the clogging degree of the screen is a first-level clogging.
[0063] It should be noted that the ratio values referred to for dividing different clogging degrees are only used as an example, and the embodiments of the present application do not limit this. The relationship between the ratio values referred to for dividing different clogging degrees and the corresponding clogging degrees satisfies: the greater the proportion of the target weight value, the higher the clogging degree.
[0064] Alternatively, the clogging degree of the screen can be determined according to the difference between the target weight value and the second weight threshold. That is, the greater the difference between the target weight value and the second weight threshold, the higher the clogging degree.
[0065] In the embodiments described above, how to perform clogging detection on the cooking device based on the first weight threshold and the second weight threshold is introduced. In another embodiment of the present application, the correlation between the first weight threshold, the second weight threshold, and the workpiece to be processed is introduced. Specifically, the first weight threshold or the second weight threshold is related to the weight of the workpiece to be processed.
[0066] Among them, the first weight threshold and the second weight threshold are positively correlated with the weight of the object to be processed. That is, the heavier the weight of the object to be processed, the greater the weight of the first material or the second material added every other measurement period T. That is, the first weight threshold and the second weight threshold change dynamically with the weight of the object to be processed.
[0067] In the foregoing embodiments, the correlation between the first weight threshold, the second weight threshold, and the object to be processed is introduced. In another embodiment of the present application, it is introduced what kind of relational expression is specifically satisfied by the correlation between the first weight threshold, the second weight threshold, and the object to be processed before. For example, the specific implementation of "the first weight threshold or the second weight threshold is related to the weight of the object to be processed" involved in the foregoing steps includes:
[0068] The first preset weight threshold is the product result of the object to be processed and the first proportionality coefficient; the second preset weight threshold is the product result of the object to be processed and the second proportionality coefficient;
[0069] Among them, the first proportionality coefficient is used to represent the proportion of the weight value of the first material or the second material in the weight value of the object to be processed after the surface removal treatment of the object to be processed when the sieve is not blocked; the second proportionality coefficient is used to represent the proportion of the weight value of the first material or the second material in the weight value of the object to be processed after the surface removal treatment of the object to be processed when the sieve is blocked.
[0070] Among them, when the sieve of the first proportionality coefficient is not blocked and the grinding time of the object to be processed reaches a cycle T, the minimum proportion of the increased weight value of the intermediate substance (for example, the first material or the second material) in the weight value of the object to be processed, for example, can be a%, and a can be but is not limited to 80.
[0071] The second proportionality coefficient is the minimum proportion of the increased weight value of the intermediate substance in the weight value of the object to be processed when the sieve is blocked and the grinding time of the object to be processed reaches a cycle T. For example, it can be b%, and b can be but is not limited to 5.
[0072] In specific implementation, when the weight of the object to be processed is x, the first weight threshold can be xa%, and the second weight threshold can be xb%. That is, the specific values of the first weight threshold and the second weight threshold change dynamically with the weight of the object to be processed.
[0073] In the foregoing embodiments, it is introduced what kind of relational expression is specifically satisfied by the correlation between the first weight threshold, the second weight threshold, and the object to be processed before. In another embodiment of the present application, it is introduced what kind of treatment is specifically performed on the cooking device when it is determined that the sieve of the cooking device is blocked. Specifically, after the sieve of the cooking device is blocked, the surface removal treatment of the object to be processed is stopped.
[0074] In a specific implementation, when it is determined that the sieve of the cooking device is blocked, the polished rice slurry of the cooking device stops removing the surface layer of the object to be processed, thereby aborting the generation of intermediate substances, such as the first material or the second material.
[0075] The embodiment of the present application also provides a method for detecting blockage of a cooking device. Taking the polished rice processing of the cooking device as an example, it can effectively solve the problem of rice flour blocking the sieve of the cooking device. Figure 3 The flowchart of this method is shown in Figure 3 and the method includes the following steps:
[0076] Step P1: Start the polished rice slurry / milling worm to process rice.
[0077] Among them, the polished rice slurry / milling worm is the processing part 1012 in the rice processing module shown in Figure 1 . The rice processing can be to control the polished rice slurry / milling worm to stir the materials in the polished rice cavity 1014 to remove the attachments on the surface of the materials and obtain the first material and the second material.
[0078] Step P2: Periodically obtain the weight data of polished rice / rice flour and determine a plurality of weight values W.
[0079] Among them, the polished rice or rice flour is equivalent to the first material or the second material in the previous embodiments of the present application. Periodically obtaining the weight data of polished rice / rice flour means obtaining the weight of polished rice once every measurement cycle or obtaining the weight of rice flour once every measurement cycle. Therefore, a plurality of rice flour quality values corresponding to a plurality of measurement cycles can be obtained, or a plurality of polished rice weight values corresponding to a plurality of measurement cycles can be obtained.
[0080] For example, by obtaining the value of the weight sensor 1 set at the bottom of the powder collecting cavity 1016 every 1 min, a plurality of rice flour weight values W can be determined; or by obtaining the value of the weight sensor 2 set at the bottom of the rice flour feeding cavity 2014 every 1 min, a plurality of polished rice weight values W can be determined; or by obtaining the value of the weight sensor 2 set at the bottom of the polished rice feeding cavity 2012 every 1 min, a plurality of polished rice weight values W can be determined. Specifically, the weight value W corresponding to the Nth cycle is based on the sensor value Q read in the Nth cycle N and the sensor value Q read in the (N - 1)th cycle N-1 The difference between them. Step P3: Determine whether the event T (W < D) occurs.
[0081] Among them, D is equivalent to the first weight threshold in the previous embodiments of the present application, which is a preset value and can represent the lower limit of the weight of polished rice or rice flour increased in a measurement cycle under the normal working state of the rice processing module 10.
[0082] If so, execute step P4; if not, execute step P2.
[0083] Step P4: Determine whether event T occurs at least N times.
[0084] It should be noted that N is a preset value. For example, it can be 3. Here, event T occurring at least N times can be at least N times discontinuously. For example, taking N = 3 as an example, the W values measured in the 1st, 3rd, and 5th cycles are all less than D. Or, event T occurring at least N times can be at least N times continuously. For example, the W values obtained in 3 consecutive measurement cycles are all less than D.
[0085] If so, it indicates that the rice sieve is blocked;
[0086] If not, it indicates that the rice sieve is not blocked, then execute step P2. That is, judge the degree of blockage and perform corresponding cleaning operations based on the degree of blockage.
[0087] That is to say, when there are N weight values W less than D among the multiple weight values W obtained within multiple measurement cycles, it is determined that the sieve is blocked. In a possible implementation, when event T occurs once, it is considered that the sieve is blocked. Making N judgments is to improve the accuracy of the determination.
[0088] Step P5: Determine whether at least one W is less than S.
[0089] Wherein, S is the second weight threshold in the previous embodiments of the present application, which is a preset safety value and can be the lower limit of the weight to ensure the normal operation of the rice processing module drive. When the weight of the polished rice or rice flour produced in a certain measurement cycle is very small, it indicates that the sieve of the cooking device is severely blocked, which will also affect the drive of the rice processing module (for example, the processing part 1012) and cannot stir normally. Therefore, if so, it indicates that the sieve is severely blocked, then execute step P6 to stop the rice processing;
[0090] If not, it indicates that the degree of blockage of the sieve does not affect the rice processing, then execute step P7.
[0092] Step P6: Stop the rice processing and at the same time prompt the user to clean the rice processing module. After cleaning, continue to execute step P5 until W≥S, then execute step P7.
[0093] When the judgment result of step P5 is yes, that is, when the sieve is severely blocked, if the drive motor of the cooking device is still used to drive the polished rice paddle to work, it will damage the drive motor and further damage the cooking device. Therefore, when the rice sieve is completely blocked, stop the rice processing to avoid damage to the rice processing module caused by forced start and operation.
[0094] Step P7: The rice processing proceeds normally, and at the same time, the self-cleaning module is activated or the user is prompted to clean the rice processing module.
[0095] When the judgment result of step P5 is negative, that is, when the rice sieve is partially blocked, if the driving motor of the cooking device continues to drive the polished rice paddle to work, the driving motor will not be damaged, nor will the cooking device be damaged. Therefore, when the rice sieve is partially blocked, the rice processing proceeds normally, that is, the driving motor of the cooking device is controlled to continue working, and the processing part 1012 continues to work..
[0096] The self-cleaning module in step P7 can be a cleaning component of the rice processing module. For example, a cleaning fan. For example, control the cleaning fan to blow air towards the sieve, so that the rice flour blocking the through holes of the sieve falls off, realizing the automatic cleaning of the sieve.
[0097] In the previous embodiments, another method for detecting blockage of a cooking device was introduced.

[0112] Or, determine the degree of blockage of the sieve according to the difference between the target weight value and the second weight threshold.
