Description

Technical Field

[0001] This invention relates to the field of control technology, and more specifically, to a food waste disposer and its control method, control device, and readable storage medium. Background Technology

[0002] When the motor in the food waste disposer rotates, it pulverizes the food waste, thus processing it.

[0003] In related technical solutions, food waste disposers use a single rotation speed to crush food waste, or the motor speed decreases as the load increases. Therefore, the mixing effect of food waste disposers is relatively poor. Summary of the Invention

[0004] The present invention aims to at least solve the technical problem that food waste disposers in the prior art or related technologies use a single rotation speed to crush food waste, or the motor speed decreases as the load increases, resulting in poor mixing effect.

[0005] Therefore, a first aspect of the present invention is to provide a control method for a food waste disposer.

[0006] A second aspect of the present invention is that a control device for a food waste disposer is provided.

[0007] A third aspect of the present invention is that it provides another control device for a food waste disposer.

[0008] A fourth aspect of the present invention is that a readable storage medium is provided.

[0009] A fifth aspect of the present invention is that a food waste disposer is provided.

[0010] In view of the above, according to a first aspect of the present invention, the present invention provides a control method for a food waste disposer, the food waste disposer including a motor, the control method comprising: when the food waste disposer is operating in an unloaded state, acquiring the input power of the motor; operating in a loaded state based on the input power being greater than a load power threshold; and maintaining unloaded operation based on the input power being less than or equal to the load power threshold; wherein, in the unloaded state, the motor operates at a first speed, and in the loaded state, the motor operates at a second speed, the second speed being greater than the first speed.

[0011] The technical solution of this invention proposes a control method for a food waste disposer. By operating the above-mentioned control method for the food waste disposer, the motor in the food waste disposer can operate at different speeds under different conditions. During this process, the speed can be automatically adjusted according to the load of the food waste disposer, so that the food waste can be fully crushed, thereby ensuring the mixing effect of the food waste disposer.

[0012] In the above technical solution, the motor can be understood as a drive motor used to crush kitchen waste. In this technical solution, the rotation of the drive motor is used to drive the agitator to rotate, thereby crushing the kitchen waste.

[0013] In the above technical solution, the unloaded state and the loaded state are the two working states of the food waste disposer.

[0014] In the no-load state, since the motor runs at the first speed, the input power of the motor is not zero. Therefore, the no-load state does not refer to the working state of the food waste disposer when there is no food waste. It can be understood as the working state when the amount of food waste processed by the food waste disposer is relatively small.

[0015] Similarly, under load, since the motor operates at the second speed, the input power of the motor is not zero. This can be understood as a working state in which the amount of food waste processed by the food waste disposer is relatively large.

[0016] In the above technical solution, the motor can operate at different speeds under different working conditions of the food waste processor, so that the food waste can be thoroughly mixed and cleaned, thus improving the processing effect of the food waste processor.

[0017] In some technical solutions, the first speed and the second speed can be selected according to the operating conditions of the food waste disposer. For example, the first speed can be 1000 RPM and the second speed can be 3000 RPM. The specific values ​​of the first speed and the second speed will not be elaborated here.

[0018] RPM stands for Revolutions Per Minute, which means the number of times the device rotates per minute.

[0019] In the above technical solution, the motor rotates at a higher speed under load, which allows the food waste fed into the food waste processor to be pulverized quickly, thereby improving work efficiency.

[0020] In addition, the control method for the food waste disposer proposed in this invention has the following additional technical features.

[0021] In some technical solutions, optionally, after operating under load, the control method for the food waste disposer further includes: entering a waiting-to-stop state based on the updated input power being greater than the no-load power threshold and the duration of operation of the food waste disposer under load being greater than or equal to a first duration; entering a waiting-to-stop state based on the updated input power being less than or equal to the no-load power threshold and the duration of operation of the food waste disposer under load being greater than a second duration; and entering a stop state when the duration of the food waste disposer in the waiting-to-stop state is greater than a third duration; wherein the first duration is greater than the second duration.

[0022] In this technical solution, by updating the input power, the load status of the food waste disposer can be continuously monitored during operation, thereby determining whether to enter a waiting shutdown state.

[0023] The waiting-to-stop state can be understood as a state before the shutdown state. In the waiting-to-stop state, the motor can maintain the first speed. If the food waste disposer is in the waiting-to-stop state for a longer period than the third period, that is, after the motor runs at the first speed for a third period, the food waste disposer officially enters the shutdown state.

[0024] In the shutdown state, the motor stops rotating, and the food waste disposer stops processing food waste.

[0025] In the above technical solution, by setting a third time interval, users are given enough time to feed the food waste, reducing the chance that the food waste disposer will directly enter a shutdown state if no food is fed in a short period of time, thereby improving the user experience of the food waste disposer.

[0026] In the above technical solution, by setting a first duration, the maximum working time of the food waste disposer under load can be measured. During this process, the situation of the food waste disposer running for a long time at a high speed can be avoided.

[0027] Specifically, if a food waste disposer runs at a high speed for an extended period of time, the motor will generate a lot of heat. At the same time, the food waste disposer itself will also generate a lot of heat. The components or motor in the food waste disposer may burn out due to the heat. By setting a first duration, the food waste disposer can be switched to a standby shutdown state after operating at a high speed for the first duration.

[0028] When the device is in standby mode, the motor operates at its lowest speed, which reduces the heat generated during operation. This obviously lowers the chance of the food waste disposer burning out due to high temperatures, thereby improving its reliability.

[0029] In the above technical solution, by setting a second duration, the minimum duration for the food waste disposer to run continuously under load can be limited. During this process, the food waste can be thoroughly crushed when there is a small amount of food waste in the disposer. At the same time, it can also ensure that the disposer can quickly enter the waiting and shutdown state when there is a small amount of food waste, thus shortening the overall working time of the food waste disposer.

[0030] In some technical solutions, the first duration, the second duration, and the third duration can be selected according to actual usage needs, which will not be elaborated here.

[0031] Clearly, in the above technical solution, the food waste disposer can automatically switch to a shutdown state after the food waste has finished dissolving.

[0032] In the relevant technical solutions, after the food waste disposer finishes grinding, it needs to be manually controlled by the user to switch to the shutdown state. If the user does not manually control it in time, there will be a waste of electricity.

[0033] By implementing the technical solution of this invention, the machine can automatically switch to a shutdown state after the food waste is finished being mixed, thus avoiding energy waste.

[0034] Optionally, in some technical solutions, the control method for food waste disposers may further include: maintaining operation in a loaded state based on the updated input power being less than or equal to the no-load power threshold and the duration of operation of the food waste disposer in a loaded state being less than or equal to a second duration.

[0035] In this technical solution, if the updated input power is less than or equal to the no-load power threshold, it is considered that the current amount of food waste entering the food waste disposer is relatively small, that is, it is in a no-load state. At this time, if the duration of the food waste disposer running in the load state has not reached the second duration, the motor needs to be controlled to continue running at the second speed to ensure that even if no food waste is entered, the food waste disposer runs in the load mode for at least the second duration.

[0036] During this process, the food waste can be thoroughly crushed and pulverized when a small amount of food waste is put into the food waste processor. At the same time, it can also ensure that the processor can quickly enter the waiting and shutdown state when a small amount of food waste is put in, thus shortening the overall working time of the food waste processor.

[0037] In some technical solutions, the control method for food waste disposers may optionally include: maintaining operation in the load state based on the updated input power being greater than the no-load power threshold and the duration of operation of the food waste disposer in the load state being less than or equal to a first duration.

[0038] In this technical solution, if the updated input power is greater than the no-load power threshold, it can be determined that the current food waste disposer is processing a large amount of food waste. At this time, if the duration of operation under load is less than the first duration, it is determined that the duration of operation of the food waste disposer at the second speed has not reached the maximum working time. At this time, the motor in the food waste disposer can continue to work, thereby ensuring that the food waste can be processed quickly.

[0039] At the same time, it can also reduce the frequency of food waste disposers switching between waiting and off-duty states and loaded states.

[0040] In some technical solutions, optionally, the food waste disposer enters a waiting-to-stop state when the continuous duration of its idle operation is greater than or equal to the fourth duration; and enters a stop state when the continuous duration of its waiting-to-stop state is greater than the third duration.

[0041] In this technical solution, if the food waste disposer remains in an unloaded state for a long time, that is, if the duration of the unloaded state is greater than or equal to the fourth hour, it can enter a waiting shutdown state. At this time, the food waste disposer can automatically switch states and then automatically enter the shutdown state.

[0042] During this process, the food waste disposer can automatically shut down when no food waste is put in for a long time, thereby reducing the power consumption of the disposer.

[0043] In some technical solutions, optionally, when in a waiting-to-stop state, the control method for the food waste disposer further includes: operating under load based on the updated input power being greater than the no-load power threshold; and maintaining a waiting-to-stop state based on the updated input power being less than or equal to the no-load power threshold, until the duration of the food waste disposer in the waiting-to-stop state is greater than a third duration.

[0044] In this technical solution, the updated input power is compared with the no-load power threshold so that, in the waiting-to-stop state, the motor's input power, i.e. the updated input power, can be used to determine whether to exit the waiting-to-stop state and enter the load-bearing state.

[0045] During this process, if a user puts food waste into the food waste disposer while it is in a waiting-to-stop state, the food waste disposer can respond to the food waste and switch its working state accordingly.

[0046] As can be seen from the above, under load, the motor runs at the second speed. Obviously, compared with the waiting and stopping state, the motor speed is increased, which enables the food waste disposer to agitate the food waste.

[0047] In some technical solutions, optionally, before acquiring the input power of the motor when the food waste disposer is operating in an unloaded state, the control method of the food waste disposer further includes: receiving a start signal of the food waste disposer in a standby state; and operating in an unloaded state in response to the start signal.

[0048] In this technical solution, the food waste disposer can switch from standby mode to no-load mode upon receiving a start signal. Since the motor will run at the first speed in no-load mode, the power consumption of the food waste disposer can be reduced when it does not need to be kept in no-load mode at all times.

[0049] In some technical solutions, the food waste disposer may optionally include a solenoid valve, and the control method of the food waste disposer may include: controlling the solenoid valve to open in response to a start signal; and controlling the solenoid valve to close after a fifth time interval following the start-up state.

[0050] In this technical solution, a solenoid valve is set up to control whether water enters the food waste disposer. When the solenoid valve is open, water is supplied to the food waste disposer, allowing it to discharge the pulverized food waste. Conversely, when the solenoid valve is closed, water supply to the food waste disposer is stopped.

[0051] In the technical solution of the present invention, the solenoid valve can open in response to the start signal and supply water to the food waste disposer before the motor rotates, which can prevent the food waste disposer from dry grinding when there is no water supply and reduce the chance of damage to the food waste disposer.

[0052] Similarly, the solenoid valve is closed only after five hours from the shutdown state, allowing water to continue supplying the food waste disposer before the motor finishes its inertial rotation.

[0053] Obviously, the technical solution of the present invention can avoid dry grinding of the food waste disposer when there is no water supply, thus reducing the chance of damage to the food waste disposer.

[0054] According to a second aspect of the present invention, the present invention provides a control device for a food waste disposer, the food waste disposer including a motor, the control device comprising: an acquisition unit for acquiring the input power of the motor when the food waste disposer is operating in an unloaded state; and a control unit for operating in a loaded state based on the input power being greater than a load power threshold, and maintaining unloaded operation based on the input power being less than or equal to the load power threshold; wherein, in the unloaded state, the motor operates at a first speed, and in the loaded state, the motor operates at a second speed, the second speed being greater than the first speed.

[0055] The technical solution of this invention proposes a control device for a food waste disposer, which enables the motor in the food waste disposer to operate at different speeds under different conditions. During this process, the speed can be automatically adjusted according to the load of the food waste disposer, so that the food waste can be fully crushed, thereby ensuring the mixing effect of the food waste disposer.

[0056] In the above technical solution, the motor can be understood as a drive motor used to crush kitchen waste. In this technical solution, the rotation of the drive motor is used to drive the agitator to rotate, thereby crushing the kitchen waste.

[0057] In the above technical solution, the unloaded state and the loaded state are the two working states of the food waste disposer.

[0058] In the no-load state, since the motor runs at the first speed, the input power of the motor is not zero. Therefore, the no-load state does not refer to the working state of the food waste disposer when there is no food waste. It can be understood as the working state when the amount of food waste processed by the food waste disposer is relatively small.

[0059] Similarly, under load, since the motor operates at the second speed, the input power of the motor is not zero. This can be understood as a working state in which the amount of food waste processed by the food waste disposer is relatively large.

[0060] In the above technical solution, the motor can operate at different speeds under different working conditions of the food waste processor, so that the food waste can be thoroughly mixed and cleaned, thus improving the processing effect of the food waste processor.

[0061] In some technical solutions, the first speed and the second speed can be selected according to the operating conditions of the food waste disposer. For example, the first speed can be 1000 RPM and the second speed can be 3000 RPM. The specific values ​​of the first speed and the second speed will not be elaborated here.

[0062] RPM stands for Revolutions Per Minute, which means the number of times the device rotates per minute.

[0063] In the above technical solution, the motor rotates at a higher speed under load, which allows the food waste fed into the food waste processor to be pulverized quickly, thereby improving work efficiency.

[0064] In addition, the control device for the food waste disposer proposed in this invention also has the following additional technical features.

[0065] In some technical solutions, optionally, after operating under load, the control unit is further configured to: enter a waiting-to-stop state based on the updated input power being greater than the no-load power threshold and the duration of operation of the food waste disposer under load being greater than or equal to a first duration; enter a waiting-to-stop state based on the updated input power being less than or equal to the no-load power threshold and the duration of operation of the food waste disposer under load being greater than a second duration; and enter a stop state when the duration of operation of the food waste disposer in the waiting-to-stop state is greater than a third duration; wherein the first duration is greater than the second duration.

[0066] In this technical solution, by updating the input power, the load status of the food waste disposer can be continuously monitored during operation, thereby determining whether to enter a waiting shutdown state.

[0067] The waiting-to-stop state can be understood as a state before the shutdown state. In the waiting-to-stop state, the motor can maintain the first speed. If the food waste disposer is in the waiting-to-stop state for a longer period than the third period, that is, after the motor runs at the first speed for a third period, the food waste disposer officially enters the shutdown state.

[0068] In the shutdown state, the motor stops rotating, and the food waste disposer stops processing food waste.

When the solenoid valve is open, water is supplied to the food waste disposer, allowing it to discharge the pulverized food waste.

[0114] To better understand the above aspects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0115] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0116] In one embodiment of this application, such as Figure 1 and Figure 9 As shown, a control method for a food waste disposer is provided. The food waste disposer 900 includes a motor 902, and the control method for the food waste disposer includes:

[0117] Step 102: Obtain the input power of the motor while the food waste disposer is running under no-load conditions;

[0118] Step 104: Based on the input power being greater than the load power threshold, operate according to the load state;

[0119] Step 106: Based on the input power being less than or equal to the load power threshold, maintain no-load operation.

[0120] In the unloaded state, the motor runs at a first speed, and in the loaded state, the motor runs at a second speed, which is greater than the first speed.

[0121] The embodiments of the present invention propose a control method for a food waste disposer. By operating the above-mentioned control method for the food waste disposer, the motor in the food waste disposer can operate at different speeds under different conditions. During this process, the speed can be automatically adjusted according to the load of the food waste disposer, so that the food waste can be fully crushed, thereby ensuring the mixing effect of the food waste disposer.

[0122] In the above embodiments, the motor can be understood as a drive motor used to shred kitchen waste. In this embodiment, the rotation of the drive motor is used to drive the agitator to rotate, thereby agitating the kitchen waste.

[0123] In the above embodiments, the unloaded state and the loaded state are two working states of the food waste disposer.

[0124] In the no-load state, since the motor runs at the first speed, the input power of the motor is not zero. Therefore, the no-load state does not refer to the working state of the food waste disposer when there is no food waste. It can be understood as the working state when the amount of food waste processed by the food waste disposer is relatively small.

[0125] Similarly, under load, since the motor operates at the second speed, the input power of the motor is not zero. This can be understood as a working state in which the amount of food waste processed by the food waste disposer is relatively large.

[0126] In the above embodiments, the motor can operate at different speeds under different working conditions of the food waste disposer, so that the food waste can be thoroughly mixed and cleaned, thus improving the processing effect of the food waste disposer.

[0127] In some embodiments, the first speed and the second speed can be selected according to the operating conditions of the food waste disposer. For example, the first speed can be 1000 RPM and the second speed can be 3000 RPM. The specific values ​​of the first speed and the second speed will not be described here.

[0128] RPM stands for Revolutions Per Minute, which means the number of times the device rotates per minute.

[0129] In the above embodiments, the motor rotates at a higher speed under load, which allows the food waste fed into the food waste processor to be pulverized quickly, thereby improving work efficiency.

[0130] In some embodiments, optionally, after operating in a loaded state, the control method for the food waste disposer further includes: entering a waiting-to-stop state based on the updated input power being greater than the no-load power threshold and the duration of the food waste disposer operating in a loaded state being greater than or equal to a first duration; entering a waiting-to-stop state based on the updated input power being less than or equal to the no-load power threshold and the duration of the food waste disposer operating in a loaded state being greater than a second duration; and entering a stop state when the duration of the food waste disposer in the waiting-to-stop state is greater than a third duration; wherein the first duration is greater than the second duration.

[0131] In this embodiment, by updating the input power, the load status of the food waste disposer can be continuously monitored during operation, thereby determining whether to enter a waiting shutdown state.

[0132] The waiting-to-stop state can be understood as a state before the shutdown state. In the waiting-to-stop state, the motor can maintain the first speed. If the food waste disposer is in the waiting-to-stop state for a longer period than the third period, that is, after the motor runs at the first speed for a third period, the food waste disposer officially enters the shutdown state.

[0133] In the shutdown state, the motor stops rotating, and the food waste disposer stops processing food waste.

[0134] In the above embodiments, by setting a third duration, sufficient time is provided for users to add food waste, reducing the likelihood that the food waste disposer will directly enter a shutdown state if no food waste is added within a short period of time, thereby improving the user experience of the food waste disposer.

[0135] In the above embodiments, by setting a first duration, the maximum working time of the food waste disposer under load can be measured. In this process, the occurrence of the food waste disposer running for a long time at a high speed can be avoided.

[0136] Specifically, if a food waste disposer runs at a high speed for an extended period of time, the motor will generate a lot of heat. At the same time, the food waste disposer itself will also generate a lot of heat. The components or motor in the food waste disposer may burn out due to the heat. By setting a first duration, the food waste disposer can be switched to a standby shutdown state after operating at a high speed for the first duration.

[0137] When the device is in standby mode, the motor operates at its lowest speed, which reduces the heat generated during operation. This obviously lowers the chance of the food waste disposer burning out due to high temperatures, thereby improving its reliability.

[0138] In the above embodiments, by setting a second duration, the minimum duration for the food waste disposer to run continuously under load can be limited. During this process, the food waste can be thoroughly crushed when there is a small amount of food waste in the disposer. At the same time, it can also ensure that the disposer can quickly enter a waiting and shutdown state when there is a small amount of food waste, thus shortening the overall working time of the food waste disposer.

[0139] In some embodiments, the first duration, the second duration, and the third duration can be set according to actual usage needs, which will not be elaborated here.

[0140] Obviously, in the above embodiments, the food waste disposer can automatically switch to a shutdown state after the food waste is finished being agitated.

[0141] In related embodiments, after the food waste disposer finishes grinding, it requires manual control by the user to switch to the shutdown state. If the user does not manually control it in time, there will be a waste of electricity.

[0142] By operating the embodiments of the present invention, the machine can automatically switch to a shutdown state after the food waste is finished being mixed, thus avoiding energy waste.

[0143] In some embodiments, the control method for a food waste disposer may optionally further include: maintaining operation in a loaded state based on the updated input power being less than or equal to an idle power threshold and the duration of operation of the food waste disposer in a loaded state being less than or equal to a second duration.

[0144] In this embodiment, if the updated input power is less than or equal to the no-load power threshold, it is considered that the food waste disposer is currently feeding relatively little food waste, that is, it is in a no-load state. At this time, if the duration of the food waste disposer running in the load state has not reached the second duration, it is necessary to control the motor to continue running at the second speed in order to ensure that even if no food waste is fed in, the food waste disposer runs in the load mode for at least the second duration.

[0145] During this process, the food waste can be thoroughly crushed and pulverized when a small amount of food waste is put into the food waste processor. At the same time, it can also ensure that the processor can quickly enter the waiting and shutdown state when a small amount of food waste is put in, thus shortening the overall working time of the food waste processor.

[0146] In some embodiments, the control method for a food waste disposer may optionally include: maintaining operation in a loaded state based on the updated input power being greater than an idle power threshold and the duration of operation of the food waste disposer in a loaded state being less than or equal to a first duration.

[0147] In this embodiment, if the updated input power is greater than the no-load power threshold, it can be determined that the current food waste processor is processing a large amount of food waste. At this time, if the duration of operation under load is less than the first duration, it is determined that the duration of operation of the food waste processor at the second speed has not reached the maximum working time. At this time, the motor in the food waste processor can continue to work, thereby ensuring that the food waste is processed quickly.

[0148] At the same time, it can also reduce the frequency of food waste disposers switching between waiting and off-duty states and loaded states.

[0149] In some embodiments, optionally, the food waste disposer enters a waiting-to-stop state when the duration of its idle operation is greater than or equal to a fourth duration; and enters a stop state when the duration of its waiting-to-stop state is greater than a third duration.

[0150] In this embodiment, if the food waste disposer remains in an unloaded state for a long time, that is, if the duration of the unloaded state is greater than or equal to the fourth duration, it can enter a waiting shutdown state. At this time, the food waste disposer can automatically switch states and then automatically enter the shutdown state.

[0151] During this process, the food waste disposer can automatically shut down when no food waste is put in for a long time, thereby reducing the power consumption of the disposer.

[0152] In some embodiments, optionally, when in a waiting-to-stop state, the control method for the food waste disposer further includes: operating in a loaded state based on the updated input power being greater than the no-load power threshold; and maintaining a waiting-to-stop state based on the updated input power being less than or equal to the no-load power threshold, until the duration of the food waste disposer in the waiting-to-stop state is greater than a third duration.

[0153] In this embodiment, the updated input power is compared with the no-load power threshold so that, in the waiting-to-stop state, the motor's input power, i.e. the updated input power, can be used to determine whether to exit the waiting-to-stop state and enter the load state.

[0154] During this process, if a user puts food waste into the food waste disposer while it is in a waiting-to-stop state, the food waste disposer can respond to the food waste and switch its working state accordingly.

[0155] As can be seen from the above, under load, the motor runs at the second speed. Obviously, compared with the waiting and stopping state, the motor speed is increased, which enables the food waste disposer to agitate the food waste.

[0156] In some embodiments, optionally, before acquiring the input power of the motor when the food waste disposer is operating in an unloaded state, the control method of the food waste disposer further includes: receiving a start signal of the food waste disposer in a standby state; and operating in an unloaded state in response to the start signal.

[0157] In this embodiment, the food waste disposer can switch from standby mode to idle mode upon receiving a start signal. Since the motor will run at the first speed in idle mode, the power consumption of the food waste disposer can be reduced when it does not need to be kept in idle mode at all times.

[0158] In some embodiments, the food waste disposer 900 may optionally include a solenoid valve 904, and the control method of the food waste disposer may further include: controlling the solenoid valve to open in response to a start signal; and controlling the solenoid valve to close after a fifth time interval following the entry into a shutdown state.

[0159] In this embodiment, a solenoid valve is provided to control whether water enters the food waste disposer. When the solenoid valve is open, water is supplied to the food waste disposer, allowing it to discharge the pulverized food waste. Conversely, when the solenoid valve is closed, water supply to the food waste disposer is stopped.

[0160] In an embodiment of the present invention, the solenoid valve can open in response to a start signal and supply water to the food waste disposer before the motor rotates, which can prevent the food waste disposer from dry grinding when there is no water supply and reduce the chance of damage to the food waste disposer.

[0161] Similarly, the solenoid valve is closed only after five hours from the shutdown state, allowing water to continue supplying the food waste disposer before the motor finishes its inertial rotation.

[0162] Obviously, in the embodiments of the present invention, the dry grinding of the food waste disposer when there is no water supply can be avoided, reducing the chance of damage to the food waste disposer.

[0163] In addition, the solenoid valve can be closed automatically without manual operation by the user, thus simplifying the user operation steps and improving the user experience of the food waste disposer.

[0164] In one embodiment, such as Figure 2 As shown, the control method for a food waste disposer includes:

[0165] Step 202, begin work.

[0166] In this step, the operation can be initiated by the user. Specifically, upon receiving the user's start command, the control solenoid valve opens immediately.

[0167] Step 204: The solenoid valve is opened.

[0168] Specifically, the motor is started 5 seconds after the solenoid valve is opened.

[0169] Step 206: The motor starts agitating.

[0170] In this step, the motor agitates at a low speed for a certain period of time, and then a load test is performed. The low speed can be the first speed.

[0171] Step 208, mixing complete.

[0172] In this step, either step 210 or step 212 is selected based on the load detection results.

[0173] Step 210, No-load determination.

[0174] In this step, the motor agitates at a low speed and performs real-time load monitoring.

[0175] Step 212, load determination.

[0176] In this step, if a load is detected, agitation is performed at a higher speed, which is also the second speed in this application.

[0177] Step 214, wait for the machine to stop.

[0178] In this step, after the mixing is complete, the motor is run under no-load for 15 seconds before being stopped.

[0179] Step 216: The motor stops agitating.

[0180] In this step, the motor can stop agitating either manually by the user or automatically enter the shutdown state.

[0181] Step 218, the solenoid valve is closed.

[0182] In this step, the solenoid valve is closed 10 seconds after the motor stops running. This 10 seconds is also the fifth duration in this invention.

[0183] Step 220, work completed.

[0184] like Figure 3 As shown, the food waste disposer can switch between standby, no-load, loaded, and waiting-to-stop states.

[0185] like Figure 3As shown, the food waste disposer also has a fault state. When a fault occurs, regardless of the food waste disposer's current state, it will enter a fault state and will not be able to work.

[0186] like Figure 4 As shown, the state switching process of a food waste disposer includes:

[0187] Step 402, no-load state.

[0188] Step 404: Is the load on? If the result is yes, proceed to step 406; if the result is no, proceed to step 408.

[0189] Step 406, Loaded state.

[0190] Step 408: If the no-load operation lasts for a certain period of time, if the judgment result is yes, proceed to step 410; if the judgment result is no, proceed to step 408.

[0191] Here, a certain duration is also the fourth duration in this invention.

[0192] Step 410: Wait for the machine to stop.

[0193] Step 412: Is the system unloaded? If the result is yes, proceed to step 414; if the result is no, proceed to step 416.

[0194] Step 414: Is it greater than the minimum working time under load? If the result is yes, proceed to step 410; if the result is no, proceed to step 406.

[0195] The minimum working time under load is also the second duration in this invention.

[0196] Step 416: Is it greater than the maximum working time under load? If the result is yes, proceed to step 410; if the result is no, proceed to step 406.

[0197] The maximum working time under load is also the first duration in this invention.

[0198] Step 418: Is the system unloaded? If the result is yes, proceed to step 420; if the result is no, proceed to step 406.

[0199] Step 420: When the no-load shutdown time is reached, if the judgment result is yes, the process ends; if the judgment result is no, proceed to step 410.

[0200] The downtime is also known as the third duration in this invention.

[0201] Specifically, the workflow of a food waste disposer is as follows:

[0202] Phase 1 S1 (Standby): When the food waste disposer receives a user start signal in standby mode, the solenoid valve immediately starts and automatically turns on the water supply switch to supply water for subsequent discharge of pulverized waste. The water supply is kept on continuously during the operation of the food waste disposer to avoid dry grinding and damage to the machine.

[0203] The second stage S2 (no-load state): After time T1 (e.g., 5s), the motor is started. The motor starts to rotate at a low speed n1 (e.g., 1000rpm). The low speed is to reduce noise and to distribute the food waste evenly when it is present, which is beneficial for the subsequent high-speed mixing.

[0204] The motor agitates at low speed for a duration of T2 (e.g., 2 seconds). After the load stabilizes, load detection begins. For example, the load can be detected by current or power. Load detection continues until the food waste disposer stops, including the unloaded state, the loaded state, and the waiting-to-stop state.

[0205] If there is no load for a period of time T3 (e.g., 30 seconds) after the load detection begins, meaning the actual load is less than the load threshold PL1 (e.g., 70W), the machine will directly enter the waiting shutdown state, i.e., the fourth stage. During no-load operation, i.e., when no waste is being fed, the actual running time is short and the speed is low, thus saving energy and reducing noise. Furthermore, sufficient time (T3+T4) is reserved for the user to feed waste.

[0206] The third stage, S3 (loaded state): When the actual load is detected to be greater than the load threshold PL1 (e.g., 70W), the food waste disposer is determined to enter the loaded state. At this time, the motor switches to a high speed n2 (e.g., 3000rpm) for operation. Operating at high speed helps to quickly pulverize food waste and improves work efficiency.

[0207] Among them, the food waste disposer is set to a minimum working time Tmin (e.g., 10s) when operating at high speed to ensure that it can quickly enter the waiting and shutdown state when the load is low, thereby reducing the overall working time of the disposer.

[0208] Set the maximum working time Tmax (e.g., 30s) to ensure that the garbage disposal unit can repeatedly switch to the waiting and stopping state when under load, so as to achieve better pulverization effect.

[0209] The system will automatically switch to low-speed operation when the following conditions are met:

[0210] a. The minimum working time Tmin is reached, but the maximum working time Tmax is not reached, and the actual load is less than the no-load threshold PL2 (e.g., 160W).

[0211] b. After reaching the maximum working time Tmax, switch directly to low-speed operation.

[0212] Phase 4 S4 (Waiting to stop state): When the garbage disposal unit switches to low speed operation (waiting to stop state) and remains unloaded for a period of time T4 (e.g., 15s), that is, when the actual load is less than the load threshold PL1 (e.g., 70W), it is determined that the food waste has been pulverized cleanly and the motor stops working.

[0213] If the actual load detected by the load test is still greater than the load threshold PL1 when switching to low speed operation, the food waste disposer will continue to switch to high speed operation (load state). At this time, the food waste disposer will repeatedly switch between the load state and the waiting to stop state until the food waste is completely pulverized. This switching is more obvious when the pulverization is about to be completed.

[0214] The repeated switching between the loaded state and the waiting-to-stop state is essentially a high-low speed switch. This process helps to provide different crushing forces and speed up the crushing of kitchen waste. In addition, the high-low speed switch also helps to speed up the discharge of crushed kitchen waste through the water source, thus achieving a better crushing effect.

[0215] In addition, because the load on food waste is relatively uneven and fluctuates greatly, it may not be completely pulverized when the load is low. At this time, the reserved T4 waiting shutdown time can keep the load at a low level for a long time, ensuring that the food waste can be completely pulverized.

[0216] After the motor stops working for T5 seconds (e.g., 5 seconds), the solenoid valve automatically closes, stopping the water supply. This completes the current operation of the food waste disposer, which then returns to standby mode. The delayed closing of the solenoid valve allows for continued drainage after the motor stops, ensuring that any remaining waste is thoroughly rinsed away.

[0217] In addition, the food waste disposer can receive user commands (such as remote control) to stop working at any stage of its operation, or it can stop when it reaches the maximum allowed single-use duration Tup (to prevent uncontrolled situations). At this time, the motor and solenoid valve of the disposer will stop working simultaneously and enter standby mode.

[0218] For example, such as Figure 5 As shown, after the user starts the food waste disposer, the solenoid valve immediately starts supplying water. After time T1 (5s), the motor agitates at speed n1 (1000rpm). After time T2 (2s), load detection begins. If no waste is added, the disposer runs in an unloaded state for time T3 (30s), then enters a waiting shutdown state. After running for time T4 (15s), the motor stops, and after time T5 (5s), the solenoid valve stops supplying water.

[0219] For example, such as Figure 6As shown, after the user starts the food waste disposer, the solenoid valve immediately starts supplying water. After time T1 (5s), the motor agitates at speed n1 (1000rpm). After time T2 (2s), load detection begins. If a load is detected during the no-load or waiting-to-stop state (i.e., T3, T4), the disposer will quickly enter the load state, and the motor will run at a high speed n2 (3000rpm). After reaching the maximum working time Tmax (30s), it will directly switch to low-speed operation (waiting-to-stop time). Afterwards, because the waste is not completely pulverized, the load will be detected again in the waiting-to-stop state if it exceeds the load threshold PL1 (e.g., 70W), and the disposer will also re-enter the load state. When the waste is pulverized to a certain extent, the load will decrease. If the actual load of the disposer is less than the no-load threshold PL2 (160W) before the minimum working time Tmin (10s), it will directly enter the waiting-to-stop state at the minimum working time Tmin (10s).

[0220] At this point, the actual load is at the critical state between no-load and loaded. The garbage disposal unit will repeatedly switch between loaded and standby states, and the motor will also switch between high and low speeds until the food waste is completely pulverized. This helps to provide different pulverizing forces, speeding up the pulverization of food waste. In addition, this process can also speed up the discharge of pulverized food waste, thus achieving a better pulverization effect. When the food waste is completely pulverized and enters the standby state, if no more garbage is fed, the garbage disposal unit will run for time T4 (15 seconds) and then automatically stop. If more garbage is fed, the above pulverization process will repeat.

[0221] In one embodiment, such as Figure 7 As shown, the present invention provides a control device 700 for a food waste disposer. The food waste disposer includes a motor, and the control device includes: an acquisition unit 702, used to acquire the input power of the motor when the food waste disposer is running in an unloaded state; and a control unit 704, used to operate in a loaded state based on the input power being greater than a load power threshold, and to maintain unloaded operation based on the input power being less than or equal to the load power threshold; wherein, in the unloaded state, the motor operates at a first speed, and in the loaded state, the motor operates at a second speed, the second speed being greater than the first speed.

[0222] The present invention provides a control device 700 for a food waste disposer, which enables the motor in the food waste disposer to operate at different speeds under different conditions. During this process, the speed can be automatically adjusted according to the load of the food waste disposer, so that the food waste can be fully crushed, thereby ensuring the mixing effect of the food waste disposer.

[0223] In the above embodiments, the motor can be understood as a drive motor used to shred kitchen waste. In this embodiment, the rotation of the drive motor is used to drive the agitator to rotate, thereby agitating the kitchen waste.

[0224] In the above embodiments, the unloaded state and the loaded state are two working states of the food waste disposer.

[0225] In the no-load state, since the motor runs at the first speed, the input power of the motor is not zero. Therefore, the no-load state does not refer to the working state of the food waste disposer when there is no food waste. It can be understood as the working state when the amount of food waste processed by the food waste disposer is relatively small.

[0226] Similarly, under load, since the motor operates at the second speed, the input power of the motor is not zero. This can be understood as a working state in which the amount of food waste processed by the food waste disposer is relatively large.

[0227] In the above embodiments, the motor can operate at different speeds under different working conditions of the food waste disposer, so that the food waste can be thoroughly mixed and cleaned, thus improving the processing effect of the food waste disposer.

[0228] In some embodiments, the first speed and the second speed can be selected according to the operating conditions of the food waste disposer. For example, the first speed can be 1000 RPM and the second speed can be 3000 RPM. The specific values ​​of the first speed and the second speed will not be described here.

[0229] RPM stands for Revolutions Per Minute, which means the number of times the device rotates per minute.

[0230] In the above embodiments, the motor rotates at a higher speed under load, which allows the food waste fed into the food waste processor to be pulverized quickly, thereby improving work efficiency.

[0231] Optionally, after operating under load, the control unit 704 is further configured to: enter a waiting-to-shutdown state based on the updated input power being greater than the no-load power threshold and the duration of operation of the food waste disposer under load being greater than or equal to a first duration; enter a waiting-to-shutdown state based on the updated input power being less than or equal to the no-load power threshold and the duration of operation of the food waste disposer under load being greater than a second duration; and enter a shutdown state when the duration of operation of the food waste disposer in the waiting-to-shutdown state is greater than a third duration; wherein the first duration is greater than the second duration.

[0232] In this embodiment, by updating the input power, the load status of the food waste disposer can be continuously monitored during operation, thereby determining whether to enter a waiting shutdown state.

[0233] The waiting-to-stop state can be understood as a state before the shutdown state. In the waiting-to-stop state, the motor can maintain the first speed. If the food waste disposer is in the waiting-to-stop state for a longer period than the third period, that is, after the motor runs at the first speed for a third period, the food waste disposer officially enters the shutdown state.

[0234] In the shutdown state, the motor stops rotating, and the food waste disposer stops processing food waste.

[0235] In the above embodiments, by setting a third duration, sufficient time is provided for users to add food waste, reducing the likelihood that the food waste disposer will directly enter a shutdown state if no food waste is added within a short period of time, thereby improving the user experience of the food waste disposer.

[0236] In the above embodiments, by setting a first duration, the maximum working time of the food waste disposer under load can be measured. In this process, the occurrence of the food waste disposer running for a long time at a high speed can be avoided.

[0237] Specifically, if a food waste disposer runs at a high speed for an extended period of time, the motor will generate a lot of heat. At the same time, the food waste disposer itself will also generate a lot of heat. The components or motor in the food waste disposer may burn out due to the heat. By setting a first duration, the food waste disposer can be switched to a standby shutdown state after operating at a high speed for the first duration.

[0238] When the device is in standby mode, the motor operates at its lowest speed, which reduces the heat generated during operation. This obviously lowers the chance of the food waste disposer burning out due to high temperatures, thereby improving its reliability.

[0239] In the above embodiments, by setting a second duration, the minimum duration for the food waste disposer to run continuously under load can be limited. During this process, the food waste can be thoroughly crushed when there is a small amount of food waste in the disposer. At the same time, it can also ensure that the disposer can quickly enter a waiting and shutdown state when there is a small amount of food waste, thus shortening the overall working time of the food waste disposer.

[0240] In some embodiments, the first duration, the second duration, and the third duration can be set according to actual usage needs, which will not be elaborated here.

[0241] Obviously, in the above embodiments, the food waste disposer can automatically switch to a shutdown state after the food waste is finished being agitated.

[0242] In related embodiments, after the food waste disposer finishes grinding, it requires manual control by the user to switch to the shutdown state. If the user does not manually control it in time, there will be a waste of electricity.

[0243] By operating the embodiments of the present invention, the machine can automatically switch to a shutdown state after the food waste is finished being mixed, thus avoiding energy waste.

[0244] In some embodiments, optionally, the control unit 704 is further configured to: maintain operation in the loaded state based on the updated input power being less than or equal to the no-load power threshold and the duration of operation of the food waste disposer in the loaded state being less than or equal to the second duration.

[0245] In this embodiment, if the updated input power is less than or equal to the no-load power threshold, it is considered that the food waste disposer is currently feeding relatively little food waste, that is, it is in a no-load state. At this time, if the duration of the food waste disposer running in the load state has not reached the second duration, it is necessary to control the motor to continue running at the second speed in order to ensure that even if no food waste is fed in, the food waste disposer runs in the load mode for at least the second duration.

[0246] During this process, the food waste can be thoroughly crushed and pulverized when a small amount of food waste is put into the food waste processor. At the same time, it can also ensure that the processor can quickly enter the waiting and shutdown state when a small amount of food waste is put in, thus shortening the overall working time of the food waste processor.

[0247] In some embodiments, optionally, the control unit 704 is further configured to: maintain operation in the loaded state based on the updated input power being greater than the no-load power threshold and the duration of operation of the food waste disposer in the loaded state being less than or equal to a first duration.

[0248] In this embodiment, if the updated input power is greater than the no-load power threshold, it can be determined that the current food waste processor is processing a large amount of food waste. At this time, if the duration of operation under load is less than the first duration, it is determined that the duration of operation of the food waste processor at the second speed has not reached the maximum working time. At this time, the motor in the food waste processor can continue to work, thereby ensuring that the food waste is processed quickly.

[0249] At the same time, it can also reduce the frequency of food waste disposers switching between waiting and off-duty states and loaded states.

[0250] In some embodiments, optionally, the control unit 704 is further configured to: enter a waiting-to-stop state based on the duration of the food waste disposer operating in an unloaded state being greater than or equal to a fourth duration; and enter a stop state when the duration of the food waste disposer being in the waiting-to-stop state is greater than a third duration.

[0251] In this embodiment, if the food waste disposer remains in an unloaded state for a long time, that is, if the duration of the unloaded state is greater than or equal to the fourth duration, it can enter a waiting shutdown state. At this time, the food waste disposer can automatically switch states and then automatically enter the shutdown state.

[0252] During this process, the food waste disposer can automatically shut down when no food waste is put in for a long time, thereby reducing the power consumption of the disposer.

[0253] In some embodiments, optionally, in the waiting-to-stop state, the control unit 704 is further configured to: operate in a loaded state based on the updated input power being greater than the no-load power threshold; and maintain the waiting-to-stop state based on the updated input power being less than or equal to the no-load power threshold until the duration of the food waste disposer in the waiting-to-stop state is greater than a third duration.

[0254] In this embodiment, the updated input power is compared with the no-load power threshold so that, in the waiting-to-stop state, the motor's input power, i.e. the updated input power, can be used to determine whether to exit the waiting-to-stop state and enter the load state.

[0255] During this process, if a user puts food waste into the food waste disposer while it is in a waiting-to-stop state, the food waste disposer can respond to the food waste and switch its working state accordingly.

[0256] As can be seen from the above, under load, the motor runs at the second speed. Obviously, compared with the waiting and stopping state, the motor speed is increased, which enables the food waste disposer to agitate the food waste.

[0257] In some embodiments, optionally, before acquiring the input power of the motor when the food waste disposer is operating in an unloaded state, the control unit 704 is further configured to: receive a start signal from the food waste disposer in a standby state; and operate in an unloaded state in response to the start signal.

[0258] In this embodiment, the food waste disposer can switch from standby mode to idle mode upon receiving a start signal. Since the motor will run at the first speed in idle mode, the power consumption of the food waste disposer can be reduced when it does not need to be kept in idle mode at all times.

[0259] In some embodiments, the food waste disposer may optionally include a solenoid valve, and the control unit 704 is further configured to: control the solenoid valve to open in response to a start signal; and control the solenoid valve to close after a fifth duration following the entry into a shutdown state.

[0260] In this embodiment, a solenoid valve is provided to control whether water enters the food waste disposer. When the solenoid valve is open, water is supplied to the food waste disposer, allowing it to discharge the pulverized food waste. Conversely, when the solenoid valve is closed, water supply to the food waste disposer is stopped.

[0261] In an embodiment of the present invention, the solenoid valve can open in response to a start signal and supply water to the food waste disposer before the motor rotates, which can prevent the food waste disposer from dry grinding when there is no water supply and reduce the chance of damage to the food waste disposer.

[0262] Similarly, the solenoid valve is closed only after five hours from the shutdown state, allowing water to continue supplying the food waste disposer before the motor finishes its inertial rotation.

[0263] Obviously, in the embodiments of the present invention, the dry grinding of the food waste disposer when there is no water supply can be avoided, reducing the chance of damage to the food waste disposer.

[0264] In one embodiment, such as Figure 8 As shown, the present invention provides a control device 800 for a food waste disposer, including a processor 802 and a memory 804. The memory 804 stores programs or instructions that can be executed on the processor 802. When the program or instructions are executed by the processor 802, they implement the steps of the control method for the food waste disposer as described above.

[0265] In one embodiment, the present invention provides a readable storage medium storing a program or instructions that, when executed by a processor, implement the steps of the control method for a food waste disposer as described above.

[0266] In one embodiment, the present invention provides a food waste disposer, comprising: a control device as described in any of the above-described food waste disposers; and / or a readable storage medium as described above.
