Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a cleaning method suitable for users to add cleaning liquid by themselves. Background Art

[0002] After using the wall breaker, cleaning liquid needs to be added for self-cleaning. In the related art, after the cleaning liquid soaks the residue on the cup wall, the cleaning liquid can be added and heated to 70°C. During the heating process, the cup wall is stirred to keep it soaked, and finally a fixed high-speed stirring is used to flush the residue. However, after the wall breaker processes high-protein materials, the high-protein materials will stick to the cup body and are difficult to clean, and the back of the cup body's spoiler ribs cannot be effectively cleaned, resulting in poor cleaning effect.

[0003] In the existing solution with patent application number CN201810851762.0, the food processor rinses the cup lid with the help of an additional circulation pipe and a spray device, which is more complicated to implement and increases the implementation cost.

[0004] In the existing solution with patent application number CN202011618285.7, a steaming and fumigation cleaning solution is proposed to solve the problem that the residue covering the surface of the grinding chamber cannot be cleaned after each soymilk machine makes a drink. The solution mainly uses the temperature difference between hot and cold to clean the dirt. However, for high-protein and high-concentration slurries, such as traditional soymilk, high-fiber or delicate porridge, alternating high and low temperatures makes rice grains and protein particles adhere more firmly, making them difficult to clean thoroughly.

[0005] In the existing solution with patent application number CN201911155881.3, the food processor with a water tank can quantitatively take in water multiple times during automatic cleaning, so there will be no problem of large differences in the amount of water each time the user manually adds water. However, for traditional food processors without a water tank and with a detachable cup body and main machine, the user needs to manually add water to achieve automatic cleaning of the machine. This will cause the cleaning liquid to overflow or the cleaning effect to be incomplete due to the different amount of water added each time. Summary of the invention

[0006] The purpose of the embodiments of the present application is to provide a cleaning method suitable for users to add cleaning liquid by themselves, thereby effectively improving the cleaning effect of self-cleaning.

[0007] The cup body receives the cleaning liquid added by the user;

[0008] The brushless motor drives the crushing blade to rotate and stir the cleaning liquid in the cup, so that the cleaning liquid in the cup is flushed to the top of the cup wall;

[0009] The cleaning liquid in the cup is heated to increase the temperature of the cleaning liquid in the cup, and the steaming state is controlled to reach a preset steaming time;

[0010] The brushless motor drives the crushing blade to rotate forward and reversely and drives the cleaning liquid in the cup to rotate forward and reversely to flush the material-facing surface and the material-receiving surface of the spoiler rib.

[0011] In one embodiment, the method of driving the crushing blade to rotate forward and reversely and driving the cleaning liquid in the cup to rotate forward and reversely by the brushless motor includes:

[0012] The brushless motor drives the crushing blade to rotate forward and reversely according to a specified speed to drive the cleaning liquid in the cup to rotate forward and reversely; wherein the specified speed is negatively correlated with the capacity of the cleaning liquid in the cup, so that the cleaning liquid can be flushed to the top of the cup wall.

[0013] In one embodiment, the cup body receives the cleaning liquid added by the user for one-time access and is used to perform the cleaning method. During multiple times of the cleaning method, the specified rotation speed is negatively correlated with the volume of the cleaning liquid in the cup.

[0014] In one embodiment, before the brushless motor drives the crushing blade to rotate forward and reversely according to the specified speed to drive the cleaning liquid in the cup to rotate forward and reversely, the method further includes:

[0015] During the heating of the cleaning liquid in the cup, determining the heating rate;

[0016] determining the volume of the cleaning liquid in the cup according to the heating rate;

[0017] According to the volume of the cleaning liquid in the cup, a matching rotation speed is determined as the designated rotation speed.

[0018] In one embodiment, the heating speed is determined by the target time taken for the cleaning liquid in the cup to heat up from the first set temperature to the second set temperature;

[0019] Determining the volume of the cleaning liquid in the cup according to the heating speed includes:

[0020] Searching for a sample duration matching the target duration in a duration-capacity table; wherein the duration-capacity table includes a mapping relationship between multiple sample durations and sample capacities;

[0021] The sample volume corresponding to the sample duration found is used as the volume of the cleaning liquid in the cup.

[0022] In one embodiment, determining a matching rotation speed as the designated rotation speed according to the volume of the cleaning liquid in the cup includes:

[0023] Searching for a sample capacity matching the capacity in a capacity-speed table; wherein the capacity-speed table includes a mapping relationship between a plurality of sample capacities and speeds;

[0024] The speed corresponding to the sample capacity found is used as the specified speed.

[0025] In one embodiment, the duration-capacity table includes a plurality of sample capacities determined by the cleaning liquid capacity range and the number of capacity divisions; wherein the cleaning liquid capacity range is from X to Y, the number of capacity divisions is n, the capacity of each portion is w, w=(YX) / n, the sample capacity is X+i*w, and the value range of i is from 0 to n;

[0026] The capacity-speed table includes a plurality of sample capacities determined by the cleaning liquid capacity range and the number of capacity divisions; wherein the cleaning liquid capacity range is from X to Y, the number of capacity divisions is n, the capacity of each portion is w, w=(YX) / n, the sample capacity is X+i*w, and the value range of i is from 0 to n;

[0027] In one embodiment, the duration-capacity table is generated in the following manner:

[0028] When the cleaning liquid in the cup is at each of the multiple sample volumes, heating the cleaning liquid in the cup to obtain the time for the cleaning liquid in the cup to heat from the first set temperature to the second set temperature as the sample time corresponding to the sample volume;

[0029] Based on the mapping relationship between the multiple sample capacities and the multiple sample durations, the duration-capacity table is generated;

[0030] The capacity-speed table is generated in the following manner:

[0031] When the cleaning liquid in the cup is at each of the multiple sample capacities, the cleaning liquid in the cup is controlled to rotate at multiple candidate rotational speeds, and the lowest candidate rotational speed at which the cleaning liquid in the cup is flushed to the cup cover sealing ring during the rotation is used as the rotational speed corresponding to the sample capacity;

[0032] The capacity-rotation speed table is generated based on a mapping relationship between a plurality of sample capacities and a plurality of rotation speeds.

[0033] In one embodiment, the cup body is a double-layer cup body, and the method further comprises:

[0034] After executing the step of driving the crushing blade to rotate forward and reversely by the brushless motor and driving the cleaning liquid in the cup to rotate forward and reversely, driving the crushing blade to rotate at a low speed by the brushless motor and stirring the cleaning liquid in the cup; wherein the low-speed rotation is a rotation with a rotation speed less than a target rotation speed threshold;

[0035] When the temperature of the cleaning liquid in the cup is lower than the boiling point, the cleaning liquid in the cup is heated to allow the water vapor in the interlayer of the double-layer cup body to evaporate continuously.

[0036] In one embodiment, the step of heating the cleaning liquid in the cup to increase the temperature of the cleaning liquid in the cup includes:

[0037] The cleaning liquid in the cup is heated at a first set power until the cleaning liquid in the cup is heated to a second set temperature;

[0038] When the temperature of the cleaning liquid in the cup reaches the second set temperature, the cleaning liquid in the cup is heated with a second set power so that the cleaning liquid in the cup is heated to boiling; wherein the second set power is less than the first set power.

[0039] In the present application, after the cleaning liquid in the high-speed stirring cup is soaked with the food residue, the cleaning liquid in the cup is heated to steam the food residue, so that the residue can be made easier to clean; further, when the crushing knife rotates forward, it can drive the cleaning liquid in the cup to rotate forward to flush the facing surface of the spoiler ribs; when the crushing knife rotates reversely, it can drive the cleaning liquid in the cup to reverse to flush the back surface of the spoiler ribs. In the case of only rotating the crushing knife forward, although the facing surface of the spoiler ribs can be cleaned, the back surface of the spoiler ribs cannot be flushed. During the processing, the back surface cannot be impacted by the cleaning liquid, and the air between the back surface and the particles such as rice grains is squeezed out under the action of the high temperature of the inner wall of the cup body, so that the particles adhere firmly and cannot be removed. In this solution, by repeatedly flushing the front and back sides, the cleaning effect of the food residue (such as high-protein materials) attached to the spoiler ribs can be effectively improved, and the problem that the back surface of the spoiler ribs cannot be effectively cleaned can be solved.

[0040] As for the inner wall of the cup, the cleaning liquid in the cup can be flushed forward and reversely, which can achieve better cleaning effect than flushing in a unidirectional state. The closer the position of the crushing knife is to the rotation center, the smaller the linear speed during rotation. Through the alternating forward and reverse rotation mode, the cleaning liquid in the cup can form a shock wave when the rotation direction is switched, thereby effectively flushing various positions of the crushing knife and improving the cleaning effect of the crushing knife.

[0041] In the present application, after high-speed stirring to rinse the top of the cup wall, high-temperature steaming and forward and reverse stirring can achieve a good cleaning effect on the entire cup body at a low hardware cost. In addition, since steaming and cleaning are performed at high temperature rather than alternating high and low temperatures, it can avoid making rice grains and protein objects adhere more firmly, thereby improving the cleaning effect of such residues.

[0042] Since the specified speed of the brushless motor is adaptive to the capacity of the cleaning liquid in the cup during the forward and reverse rotation, it can ensure that in the process of driving the crushing knife forward and backward at the specified speed to drive the cleaning liquid in the cup forward and reverse rotation, it can not only flush to the top of the cup wall, thereby effectively flushing the foam and residue on the top of the cup wall, thereby obtaining a good cleaning effect, but also avoid the problem of the cleaning liquid pushing open the cup lid and overflowing during the flushing process due to the specified speed being too high.

[0052] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0053] Similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0054] like Figure 1 As shown, this embodiment provides an electronic device 1, including: at least one processor 11 and a memory 12, Figure 1A processor 11 is taken as an example. The processor 11 and the memory 12 are connected via a bus 10. The memory 12 stores instructions that can be executed by the processor 11. The instructions are executed by the processor 11 so that the electronic device 1 can execute all or part of the process of the method in the following embodiment. In one embodiment, the electronic device 1 can be a controller of a food processor, which is used to execute a cleaning method suitable for users to add cleaning liquid by themselves.

[0055] The memory 12 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable red-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, disk or optical disk.

[0056] The present application also provides a computer-readable storage medium, which stores a computer program. The computer program can be executed by the processor 11 to complete the cleaning method provided in the present application that is suitable for users to add cleaning liquid by themselves.

[0057] See also Figure 2 , is a flow chart of a cleaning method for users to add cleaning liquid by themselves, provided in one embodiment of the present application. Figure 2 As shown, the method may include the following steps 210 to 230.

[0058] Step 210: The cup body receives the cleaning liquid added by the user.

[0059] Step 220: The pulverizing blade is driven by a brushless motor to rotate and stir the cleaning liquid in the cup so that the cleaning liquid in the cup is flushed to the top of the cup wall.

[0060] The solution is applied to a food processor, which includes a cup body, a crushing blade driven by a brushless motor is arranged in the cup body, and a spoiler rib is arranged on the inner wall of the cup body. Exemplarily, the food processor can be a wall breaking machine.

[0061] After the food processor processes food, there may be food residues on the inner wall of the cup, the crushing blade and the spoiler ribs. Therefore, after each processing of food, the user can pour cleaning liquid into the cup so that the food processor can perform self-cleaning. Here, the cleaning liquid can be clean water, water with detergent added, water with disinfectant added, etc.

[0062] The cup body can receive the cleaning liquid added by the user. Before the food processor automatically cleans, the user can add the cleaning liquid at one time, so the cup body can receive all the cleaning liquid used for this cleaning at one time.

[0063] The controller of the food processor can drive the crushing blade to rotate at a speed greater than a first speed threshold through a brushless motor, and stir the cleaning liquid in the cup so that the cleaning liquid in the cup is washed to the cup lid sealing ring on the top of the cup wall. Here, the first speed threshold can be configured based on experience. When the brushless motor drives the crushing blade to rotate at a speed greater than the first speed threshold, it can be ensured that the cleaning liquid in the cup can be washed to the cup lid sealing ring after stirring.

[0064] In this case, after the cleaning liquid is added to the high-speed blender cup, the food residues in various locations in the cup can be fully soaked.

[0065] Step 230: heating the cleaning liquid in the cup to increase the temperature of the cleaning liquid in the cup, and controlling the steaming state to reach a preset steaming time.

[0066] The duration of fumigation is the duration of fumigating the food residue with steam, which can be configured as needed. For example, the duration of fumigation can be 5 minutes, 6 minutes, 8 minutes, 10 minutes, etc.

[0067] After soaking the food residue in the cup, the controller can heat the cleaning liquid in the cup so that the cleaning liquid can be heated and put into a steaming state.

[0068] Preferably, the steaming state is a state in which the cleaning liquid is heated to boiling and then continues to boil for steaming. At this time, when the cleaning liquid in the cup boils, it can be heated continuously until the boiling food reaches the steaming time. Alternatively, the steaming state can be a state in which the cleaning liquid is steamed at a high temperature but not boiling (for example: the temperature of the cleaning liquid is maintained within a range of 5°C from the boiling point).

[0069] During this process, the food residue can be continuously steamed at high temperature to facilitate subsequent cleaning.

[0070] During the execution of step 230 , the pulverizing blade can be intermittently driven by a brushless motor to rotate at high speed and stir the cleaning liquid in the cup, so that the cleaning liquid in the cup can be heated evenly.

[0071] In one embodiment, after the cleaning liquid in the cup boils, the controller can read the boiling point and save the boiling point. Here, the boiling point can be measured by a temperature sensor carried by the food processor. Since the air pressure in different regions is different, the boiling point in different regions will also be different. By saving the actual boiling point of the cleaning liquid in the cup when it boils, it can be used for other subsequent functions.

[0072] Step 240: The brushless motor drives the crushing blade to rotate forward and reversely and drives the cleaning liquid in the cup to rotate forward and reversely to flush the material-facing surface and the material-receiving surface of the spoiler rib.

[0073] The controller can drive the crushing blade to rotate forward and reverse through the brushless motor, thereby driving the cleaning liquid in the cup to rotate forward and reverse.

[0074] During this process, when the pulverizer rotates forward, it can drive the cleaning liquid in the cup to rotate forward to flush the material-facing surface of the spoiler ribs; when the pulverizer rotates reversely, it can drive the cleaning liquid in the cup to reverse to flush the material-backing surface of the spoiler ribs. While keeping the cleaning liquid in the cup at a high temperature, by repeatedly flushing the front and back sides, the cleaning effect of food residues attached to the spoiler ribs (such as high-protein materials) can be effectively improved, solving the problem that the material-backing surface of the spoiler ribs cannot be effectively cleaned.

[0075] As for the inner wall of the cup, the forward and reverse flushing of the cleaning liquid in the cup under high temperature can achieve better cleaning effect than the unidirectional flushing under normal temperature. The closer the position of the crushing knife is to the rotation center, the smaller the linear speed during rotation. Through the forward and reverse alternating rotation mode, the cleaning liquid in the cup can form a shock wave when the rotation direction is switched, thereby effectively flushing all positions of the crushing knife and improving the cleaning effect of the crushing knife.

[0076] In one embodiment, during the execution of step 240, the liquid in the cup is heated and is in a high temperature state during the forward and reverse rotation process, and the high temperature state is a state where the temperature is greater than a specified temperature.

[0077] Here, the specified temperature is the temperature at which the cleaning liquid in the cup can obtain a good self-cleaning effect during the forward and reverse rotation. The specified temperature can be configured based on experience. For example, the specified temperature can be 85°C, 90°C, 95°C, etc. The material-facing surface of the spoiler rib is the surface opposite to the rotation direction of the crushing knife when the crushing knife rotates forward; the material-backing surface of the spoiler rib is the surface opposite to the rotation direction of the crushing knife when the crushing knife rotates reversely.

[0078] In one embodiment, the brushless motor is controlled to drive the crushing blade to rotate forward and reversely while the cleaning liquid in the cup can be continuously heated, thereby ensuring that the cleaning liquid in the cup is in a high temperature state. In another embodiment, the brushless motor is controlled to drive the crushing blade to rotate forward and reversely, and the heating of the cleaning liquid in the cup can be performed in a time-sharing manner. For example: the crushing blade can be controlled by the brushless motor to rotate forward for 30 seconds, stop rotating after 30 seconds, and heat the cleaning liquid in the cup for 10 seconds. After heating for 10 seconds, the crushing blade can be controlled by the brushless motor to rotate reversely for 30 seconds, stop rotating after 30 seconds, and heat the cleaning liquid in the cup for 10 seconds, and the cycle is repeated multiple times.

[0079] Through this measure, the cleaning liquid in the cup can be controlled to be in a high temperature state during the forward and reverse flushing process, so that it is easier to dissolve the crushing blade, the spoiler ribs and the food residues attached to the cup wall, so as to obtain a better cleaning effect.

[0080] In one embodiment, when executing step 240, the controller can drive the crushing blade to rotate forward and reversely according to a specified speed through a brushless motor to drive the cleaning liquid in the cup to rotate forward and reversely.

[0081] The designated rotation speed is negatively correlated with the volume of the cleaning liquid in the cup. The larger the volume of the cleaning liquid in the cup, the smaller the designated rotation speed; conversely, the smaller the volume of the cleaning liquid in the cup, the larger the designated rotation speed.

[0082] Preferably, the designated speed is the lowest speed at which the cleaning liquid in the cup can flush the cup lid seal ring when stirring under the corresponding capacity. In this case, when the crushing blade is driven forward and reversely according to the designated speed, the cleaning liquid in the cup can just flush the cup lid seal ring on the top of the cup wall during the stirring process.

[0083] Preferably, when the pulverizing blade is driven forward and reversely by the brushless motor according to the specified speed, the forward and reverse speeds are the same, both of which are the specified speeds. Alternatively, when the pulverizing blade is driven forward and reversely by the brushless motor according to the specified speed, the forward and reverse speeds may be different, and the forward or reverse speed may be the specified speed.

[0084] During the self-cleaning process of the food processor, the higher the speed of the crushing blade, the greater the noise it emits. By driving the crushing blade forward and reverse at a specified speed adapted to the capacity of the cleaning liquid in the cup, the noise emitted during the self-cleaning process can be controlled as much as possible while ensuring the cleaning effect, thereby improving the user experience of the food processor and reducing energy consumption during the self-cleaning process. At this time, since the specified speed of the brushless motor is adaptive to the capacity of the cleaning liquid in the cup, it can be ensured that in the process of driving the crushing blade forward and reverse at a specified speed to drive the cleaning liquid in the cup forward and reverse, it can be flushed to the top of the cup wall, thereby effectively flushing the foam and residue on the top of the cup wall, thereby obtaining a good cleaning effect, and can avoid the problem of the cleaning liquid pushing open the cup lid and overflowing during the flushing process due to the specified speed being too high.

[0085] In one embodiment, the cup receives the cleaning liquid added by the user for a one-time access and is used to perform a complete cleaning method. In other words, the cup receives all the cleaning liquid required for a cleaning method at one time. In multiple cleaning methods, the specified rotation speed is negatively correlated with the volume of the cleaning liquid in the cup.

[0086] In this case, in the two cleaning processes, since the volume of cleaning liquid manually added by the user is different each time, when executing step 240 in the two cleaning processes to drive the crushing blade forward and reverse, the larger the cleaning liquid volume, the smaller the specified rotation speed, thereby achieving the adaptation of the specified rotation speed to the cleaning liquid volume, thereby ensuring that in the process of driving the crushing blade forward and reverse at the specified rotation speed to drive the cleaning liquid in the cup forward and reverse, it can not only rinse to the top of the cup wall, thereby effectively flushing the foam and residue on the top of the cup wall, thereby obtaining a good cleaning effect, but also avoid the problem of the cleaning liquid pushing open the cup cover and overflowing during the flushing process due to the specified rotation speed being too high.

[0087] In one embodiment, before executing step 240, a specified speed may be determined. Figure 3 , is a flow chart of a method for determining a specified rotation speed provided in an embodiment of the present application, such as Figure 3 As shown, the method may include the following steps 310 to 330.

[0088] Step 310: Determine the heating speed during the heating of the cleaning liquid in the cup.

[0089] During the process of executing step 230, the heating speed of the cleaning liquid in the cup can be obtained. Here, the heating speed can be represented by the temperature increase per unit time.

[0090] Step 320: Determine the volume of the cleaning liquid in the cup according to the heating speed.

[0091] Under the same heating power, the larger the volume of the cleaning liquid in the cup, the longer it takes to increase the temperature by 1 degree Celsius. Therefore, the heating speed is inversely proportional to the volume of the cleaning liquid in the cup. The faster the heating speed, the smaller the volume of the cleaning liquid in the cup; conversely, the slower the heating speed, the larger the volume of the cleaning liquid in the cup.

[0092] The controller can determine the volume of the cleaning liquid in the cup corresponding to the heating speed according to a preset conversion method.

[0093] In one embodiment, the heating speed can be determined by the target time taken for the cleaning liquid in the cup to heat up from the first set temperature to the second set temperature. Here, the first set temperature and the second set temperature can be configured as needed. For example, the first set temperature is 60°C and the second set temperature is 80°C. Alternatively, the first set temperature is 50°C and the second set temperature is 75°C.

[0094] The longer the target time is, the slower the heating speed is.

[0095] In this case, when executing step 320, the controller may search the duration-capacity table for a sample duration that matches the target duration. The duration-capacity table includes a mapping relationship between multiple sample durations and sample capacities. The duration-capacity table may be pre-configured in the memory of the controller.

[0096] In the duration-capacity table, the sample duration that is the same as the target duration is the sample duration that matches the target duration. Alternatively, the sample duration that is closest to the target duration in the duration-capacity table is used as the sample duration that matches the target duration.

[0097] After finding a sample duration that matches the target duration, the sample capacity corresponding to the sample duration may be used as the capacity corresponding to the target duration, that is, the capacity of the cleaning liquid in the cup.

[0098] Preferably, when a sample duration identical to the target duration cannot be found in the duration-capacity table, the capacity of the cleaning liquid in the cup can be determined between the sample capacity corresponding to the maximum sample duration that is less than the target duration and the sample capacity corresponding to the minimum sample duration that is greater than the target duration.

[0099] Step 330: Determine a matching rotation speed according to the volume of the cleaning liquid in the cup as the designated rotation speed.

[0100] After determining the volume of the cleaning liquid in the cup, the control board can convert it into a corresponding rotation speed as the specified rotation speed.

[0101] In one embodiment, when executing step 330, the control board may search for a sample capacity that matches the capacity in a capacity-speed table. The capacity-speed table includes a mapping relationship between a plurality of sample capacities and speeds. The capacity-speed table may be pre-configured in the memory of the controller.

[0102] In the capacity-tachometer, the sample capacity that is the same as the capacity of the cleaning solution in the cup is the sample capacity that matches the capacity. Alternatively, the sample capacity in the capacity-tachometer that is closest to the capacity of the cleaning solution in the cup is the sample capacity that matches the capacity.

[0103] After finding the sample volume that matches the volume of the cleaning liquid in the cup, the rotation speed corresponding to the sample volume can be used as the designated rotation speed.

[0104] Preferably, when a sample capacity that is the same as the capacity of the cleaning liquid in the cup cannot be found in the capacity-rotation speed table, the rotation speed corresponding to the minimum sample capacity that is larger than the capacity of the cleaning liquid in the cup can be used as the designated rotation speed.

[0105] Through the above measures, the volume of the cleaning liquid in the cup can be effectively determined by the heating speed, and then the specified rotation speed can be converted according to the volume, so that meaningless high noise can be avoided when step 240 is subsequently executed.

[0106] In one embodiment, the duration-capacity table includes a plurality of sample capacities determined by a cleaning liquid capacity range and a number of capacity divisions.

[0107] The cleaning liquid capacity ranges from X to Y, and the values ​​of X and Y can be determined according to the cleaning liquid capacity that may be poured into the cup of the food processor during self-cleaning. For example, X is 400 ml (milliliters) and Y is 1000 ml. The number of capacity divisions is n, where n can be configured as needed, and the larger n is, the finer the division.

[0108] The volume of each portion is w, w=(YX) / n, for example, n is 100, X is 400 ml (milliliters), Y is 1000 ml, then w is 6 ml. In this case, the sample volume is X+i*w, and i ranges from 0 to n.

[0109] At this time, there are n+1 sample durations in the duration-capacity table. The following Table 1 shows a duration-capacity table:

[0110]

[0111] Table 1

[0112] The capacity-speed table includes multiple sample capacities determined by cleaning fluid capacity range and capacity division number.

[0113] The cleaning liquid capacity ranges from X to Y, and the values ​​of X and Y can be determined according to the cleaning liquid capacity that may be poured into the cup of the food processor during self-cleaning. For example, X is 400 ml (milliliters) and Y is 1000 ml. The number of capacity divisions is n, where n can be configured as needed, and the larger n is, the finer the division.

[0114] The volume of each portion is w, w=(YX) / n, for example, n is 100, X is 400 ml (milliliters), Y is 1000 ml, then w is 6 ml. In this case, the sample volume is X+i*w, and i ranges from 0 to n.

[0115] Preferably, the capacities of the multiple samples in the capacity-speed table are the same as the capacities of the multiple samples in the duration-capacity table.

[0116] At this time, there are n+1 speeds in the capacity-speed table. Table 2 below shows a capacity-speed table:

[0117]

[0118] Table 2

[0119] In one embodiment, see Figure 4 , is a flow chart of a method for generating a duration-capacity table provided in an embodiment of the present application, such as Figure 4 As shown, for any food processing machine, its preconfigured duration-capacity table can be generated through steps 410 to 420.

[0120] Step 410: When the cleaning liquid in the cup is at each sample volume of a plurality of sample volumes, the cleaning liquid in the cup is heated to obtain the time taken for the cleaning liquid in the cup to heat up from a first set temperature to a second set temperature as the sample time corresponding to the sample volume.

[0121] After determining the multiple sample volumes divided for the food processor, the cleaning liquid in the cup can be heated when the cleaning liquid in the cup is in each sample volume, and the temperature of the cleaning liquid in the cup can be detected in real time during the heating process. When the temperature of the cleaning liquid in the cup reaches the first set temperature, timing can be performed until the temperature of the cleaning liquid in the cup reaches the second set temperature, and the time it takes for the cleaning liquid in the cup to heat up from the first set temperature to the second set temperature is obtained. Under any sample volume, after obtaining this time, this time can be used as the sample time corresponding to the sample volume.

[0122] The above process is performed for all sample sizes to obtain the sample durations corresponding to all sample sizes.

[0123] Step 420: Generate a duration-capacity table based on the mapping relationship between multiple sample capacities and multiple sample durations.

[0124] A mapping relationship between each sample capacity and its corresponding sample duration is established, thereby obtaining multiple mapping relationships, and a duration-capacity table is established based on the multiple mapping relationships.

[0125] Through the above measures, a duration-capacity table can be generated.

[0126] In one embodiment, see Figure 5 , is a flow chart of a method for generating a capacity-speed table provided in an embodiment of the present application, such as Figure 5 As shown, for any food processing machine, its preconfigured capacity-speed table can be generated through steps 510 to 520.

[0127] Step 510: When the cleaning liquid in the cup is at each sample volume of multiple sample volumes, the cleaning liquid in the cup is controlled to rotate at multiple candidate rotational speeds, and the cleaning liquid in the cup is flushed to the lowest candidate rotational speed of the cup lid sealing ring during rotation, which is used as the rotational speed corresponding to the sample volume.

[0128] After determining the multiple sample volumes divided for the food processor, when the cleaning liquid in the cup is at each sample volume, the brushless motor can be controlled to rotate at multiple candidate speeds to drive the cleaning liquid in the cup to rotate. For any sample volume, the candidate speed at which the cleaning liquid in the cup can just rinse the sealing ring of the cup cover during rotation is the lowest candidate speed that can meet the use requirements, and the lowest candidate speed is used as the speed corresponding to the sample volume.

[0129] The above process is performed for all sample capacities to obtain the rotation speeds corresponding to all sample capacities.

[0130] Step 520: Generate a capacity-speed table based on the mapping relationship between the multiple sample capacities and the multiple speeds.

[0131] A mapping relationship between each sample capacity and its corresponding rotation speed is established, thereby obtaining a plurality of mapping relationships, and a capacity-rotation speed table is established based on the plurality of mapping relationships.

[0132] Through the above measures, a capacity-speed table can be generated.

[0133] In one embodiment, after executing step 240, the inner wall of the cup body, the crushing blade and the spoiler ribs are cleaned, the crushing blade can be driven by a brushless motor to rotate at a low speed and stir the cleaning liquid in the cup. The low-speed rotation is a rotation with a rotation speed less than a target speed threshold, and here, the target speed threshold can be configured based on experience. After stirring the cleaning liquid in the cup to rinse the inner wall of the cup body, the crushing blade and the spoiler ribs, controlling the crushing blade to rotate at a low speed and stirring the cleaning liquid in the cup can avoid the deposition of food residues, so as to facilitate the subsequent pouring out of the cleaning liquid in the cup to obtain a good cleaning effect.

[0134] The cup body of the food processor is a double-layer cup body. In this case, after the food processor processes the food and pours out the food, the temperature inside the cup drops suddenly, causing the hot steam in the interlayer of the double-layer cup body to cool and liquefy, producing residual cleaning liquid that is difficult to eliminate.

[0135] To solve this problem, after executing step 240, the cleaning liquid in the cup can be kept at a high temperature. The controller can read the temperature of the cleaning liquid in the cup and determine whether the temperature is lower than the stored boiling point. When the temperature of the cleaning liquid in the cup is lower than the boiling point, the cleaning liquid in the cup can be heated. By keeping the cleaning liquid in the cup at a high temperature, the water vapor in the interlayer of the double-layer cup body can be continuously evaporated, thereby removing the liquefied mist in the interlayer.

[0136] In one implementation, when executing step 230, the cleaning liquid in the cup may be heated to boiling and then fumigated in a boiling state. The controller may heat the cleaning liquid in the cup at a first set power until the cleaning liquid in the cup is heated to a second set temperature. Here, the second set temperature is a temperature close to the boiling point. Exemplarily, the second set temperature may be 75°C, 80°C, 85°C, etc.

[0137] When the temperature of the cleaning liquid in the cup reaches the second set temperature, the controller can heat the cleaning liquid in the cup at the second set power, so that the cleaning liquid in the cup is heated to boiling. Here, the second set power is less than the first set power. Exemplarily, the first set power is the full power (rated power) of the heating body in the food processor, and the second set power is half the power of the heating body.

[0138] Through this measure, during the heating process of the cleaning liquid in the cup, the cleaning liquid in the cup can be quickly heated to a second set temperature close to the boiling point, thereby reducing the power for heating to avoid overflow of the cleaning liquid in the cup due to over-rapid heating.

[0139] See also Figure 6 , is a schematic diagram of the overall process of a cleaning method for users to add cleaning liquid by themselves, provided in one embodiment of the present application. Figure 6 As shown, after the cup body receives the cleaning liquid heated by the user, when the food processor starts self-cleaning, it first executes step 610, and drives the crushing blade to stir the cleaning liquid in the cup at high speed through the brushless motor, so that the cleaning liquid in the cup can infiltrate the food residues on the inner wall of the cup. Further, step 620 is executed to heat the cleaning liquid in the cup at full power to the second set temperature. In this process, the crushing blade can be driven by the brushless motor to stir the cleaning liquid in the cup at high speed to ensure that the cleaning liquid in the cup is heated evenly. After the cleaning liquid in the cup is heated to the second set temperature, step 630 can be executed to heat the cleaning liquid in the cup at half power to the boiling point. In this process, the capacity of the cleaning liquid in the cup and the reasonable speed adapted to the capacity can be obtained based on the heating speed. When executing step 640, the crushing blade is driven by the brushless motor to rotate forward and reverse at a reasonable speed to stir the cleaning liquid in the cup, thereby flushing the inner wall of the cup body, the material-facing surface and the back surface of the crushing blade and the spoiler ribs. In this process, the cleaning liquid in the cup can be heated at half power to ensure that the cleaning liquid in the cup is in a high temperature state. After rinsing, step 650 can be performed to heat at low power temperature control, thereby continuously evaporating the mist in the interlayer of the double-layer cup body, and driving the crushing blade to stir the cleaning liquid in the cup at a low speed to avoid the deposition of food residues.

[0140] The overall process of self-cleaning is described below with a specific embodiment.

[0141] See also Figure 7, is a schematic diagram of the overall process of a cleaning method for users to add cleaning liquid by themselves, provided in another embodiment of the present application. Figure 7 As shown, after the cup body receives the cleaning liquid heated by the user, when the food processor starts self-cleaning, it first executes step 710, and drives the crushing blade to rotate at 11000rpm (Revolutions PerMinute) through the brushless motor to stir the cleaning liquid in the cup, so that the cleaning liquid in the cup can infiltrate the food residues at various positions on the inner wall of the cup. Further, execute step 720 to heat the cleaning liquid in the cup at full power. Every 30 seconds of heating, the crushing blade is driven by the brushless motor to rotate at 10000rpm to stir the cleaning liquid in the cup. The stirring lasts for 5 seconds, and this process is repeated. During the heating process of the cleaning liquid in the cup, the target time from 60°C to 80°C is read as 4 minutes and 30 seconds. The capacity of the cleaning liquid in the cup is determined in the time-capacity table based on the target time, and then the specified speed is determined to be 8000rpm in the capacity-speed table.

[0142] When the cleaning liquid in the cup reaches 80°C, step 730 can be executed to heat the cleaning liquid in the cup at half power. Every 30 seconds of heating, the brushless motor drives the crushing blade to rotate at 10,000 rpm to stir the cleaning liquid in the cup. The stirring lasts for 5 seconds, and this process is repeated. After the cleaning liquid in the cup boils, it can be heated continuously and maintained for 5 minutes, so that the steam can fumigate the residue on the wall of the cup, so that the residue is fully soaked and easily soluble in water. In this process, the boiling point can be read and saved.

[0143] Further, step 740 can be executed to drive the crushing blade to rotate forward and reverse at a specified speed of 8000 rpm by the brushless motor to stir the cleaning liquid in the cup. In this process, the machine can rotate forward for 30 seconds, heat at half power for 10 seconds, reverse for 30 seconds, heat at half power for 10 seconds, and repeat the cycle until the duration reaches 4 minutes. By executing step 740, the inner wall of the cup body, the front and back sides of the spoiler ribs, and the crushing blade can be fully flushed.

[0144] After executing step 740, the cleaning liquid in the cup can be heated at a constant temperature to control the boiling point, so that the mist in the interlayer of the double-layer cup body can continue to evaporate. In this process, every 1 minute of heating, the brushless motor can drive the crushing blade to rotate at 5000 rpm for 5 seconds to stir the cleaning liquid in the cup, thereby preventing residue deposition. This process continues until the user takes the cup and the self-cleaning ends.
