Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a fruit and vegetable washing machine and a control method, a device, and a storage medium thereof. Background Art

[0002] Currently, most fruit and vegetable cleaning machines on the market use the following methods to clean fruits and vegetables: first, they use a mechanical spray mechanism that circulates water for cleaning; second, they use ultrasonic vibrations for cleaning. However, when pesticides, toxic heavy metals, or inorganic substances remain on the surface of fruits and vegetables and are strongly adhered to them, mechanical water circulation or ultrasonic vibration cleaning methods cannot effectively remove these strongly adhered dirt. Both methods result in varying degrees of incomplete and incomplete cleaning, resulting in a poor user experience and potentially endangering the user's health with long-term use. Summary of the Invention

[0003] The present invention proposes a fruit and vegetable cleaning machine and a control method, device, and storage medium for fruit and vegetable cleaning, so as to solve the technical problem in the prior art that mechanical water circulation flushing or ultrasonic vibration cleaning cannot effectively remove dirt strongly adhering to the surface of fruits and vegetables, resulting in incomplete and incomplete cleaning.

[0004] In one aspect of the present invention, a fruit and vegetable washing machine is provided, comprising a power supply device, a shell, and at least one group of electrohydraulic effect devices; the shell is a polyhedron structure, and the side surfaces of the polyhedron structure are symmetrical to each other. The power supply device is installed in the polyhedron structure to supply power to the at least one group of electrohydraulic effect devices. The at least one group of electrohydraulic effect devices is installed on two mutually symmetrical side surfaces of the polyhedron structure. Each electrohydraulic effect device includes a positive electrode and a negative electrode. When high voltage power is supplied to the electrohydraulic effect device, a high voltage strong electric field formed between the positive electrode and the negative electrode causes the liquid in the discharge channel to explode and generate a shock wave, thereby promoting the flow of liquid to achieve fruit and vegetable cleaning.

[0005] Furthermore, the fruit and vegetable washing machine further comprises: each group of electrohydraulic effect devices installed on two mutually symmetrical sides of the polyhedron structure work simultaneously to prevent the placement of the fruit and vegetable washing machine from being shifted due to the shock wave generated by the electrohydraulic effect.

[0006] Furthermore, the fruit and vegetable washing machine further includes: the polyhedron structure is a regular hexahedron structure, the at least one group of electrohydraulic effect devices is two groups, and the two groups of electrohydraulic effect devices are respectively installed on the four sides of the regular hexahedron structure.

[0007] Furthermore, the fruit and vegetable washing machine also includes: a group of electrohydraulic effect devices installed on the front and rear sides of the regular hexahedron structure, which work alternately with a group of electrohydraulic effect devices installed on the left and right sides of the polyhedron structure, to prevent the electrohydraulic effect devices from overheating and being damaged.

[0011] When entering the main cleaning stage, each group of electrohydraulic effect devices is controlled to perform the fruit and vegetable cleaning operation according to the cleaning control parameters corresponding to the cleaning mode.

[0012] Furthermore, the degree of contamination of the fruits and vegetables to be washed is determined based on the degree of contamination of the washing water, including:

[0013] After the pre-cleaning stage is completed, detecting a first current passing between the positive electrode and the negative electrode of the electrohydraulic effect device;

[0014] Comparing the first current with a preset current threshold to obtain a first difference value obtained by the comparison, wherein the preset current threshold is a current detected between the positive electrode and the negative electrode when the electrohydraulic effect device operates in a clean liquid environment;

[0015] The threshold range to which the first difference belongs is determined, and the degree of dirtiness of the fruits and vegetables to be washed is determined based on the threshold range.

[0016] Furthermore, the method further comprises:

[0017] When entering the main cleaning stage, detecting the second current passing between the positive electrode and the negative electrode of the electrohydraulic effect device;

[0018] When the main cleaning phase is entered and the cleaning time set by the fruit and vegetable cleaning machine is reached, the third current passing between the positive electrode and the negative electrode of the electrohydraulic effect device is detected;

[0019] Comparing the third current with the second current to obtain a second difference;

[0020] The cleanliness of the fruits and vegetables to be washed is determined based on the second difference.

[0021] Furthermore, determining the cleanliness of the fruits and vegetables to be washed according to the second difference includes:

[0022] Determining whether the second difference is less than a preset difference threshold;

[0023] If the second difference is less than the preset difference threshold, it is determined that the fruits and vegetables to be washed have been cleaned, and the user is reminded that the washing of the fruits and vegetables is completed;

[0024] If the second difference is greater than or equal to the preset difference threshold, it is determined that the fruits and vegetables to be washed are not clean, and the user is reminded to change the water to perform the fruit and vegetable washing operation again.

[0025] Furthermore, the cleaning control parameters include: cleaning time and / or cleaning intensity;

[0026] When entering the main cleaning stage, controlling each group of electrohydraulic effect devices to perform the fruit and vegetable cleaning operation according to the cleaning control parameters corresponding to the cleaning mode includes:

[0027] Acquire a cleaning time and / or cleaning intensity corresponding to the cleaning mode;

[0028] According to the cleaning time and / or cleaning intensity, the groups of electrohydraulic effect devices installed on the mutually symmetrical sides of the polyhedron structure are controlled to work alternately.

By providing at least one group of electrohydraulic effect devices and supplying high voltage power to the electrohydraulic effect devices, a high-voltage strong electric field formed between the positive and negative electrodes of the electrohydraulic effect devices causes the liquid in the discharge channel to explode and generate a shock wave, thereby promoting the flow of liquid to clean the fruits and vegetables. This effectively cleans the dirt that strongly adheres to the surface of the fruits and vegetables, thereby thoroughly cleaning the fruits and vegetables and improving the user experience.

[0044] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0045] Figure 1-2 FIG. 1 is a schematic diagram showing the overall structure of the fruit and vegetable cleaning machine proposed in an embodiment of the present invention. Figure 1-2As shown, the fruit and vegetable washing machine proposed in an embodiment of the present invention includes a power supply device, a housing 1 and at least one group of electrohydraulic effect devices 3; the housing 1 is a polyhedron structure, and the side surfaces of the polyhedron structure are symmetrical to each other. The power supply device is installed in the polyhedron structure to supply power to the at least one group of electrohydraulic effect devices 3. The at least one group of electrohydraulic effect devices 3 is installed on two symmetrical side surfaces of the polyhedron structure. Each electrohydraulic effect device 3 includes a positive electrode 3a and a negative electrode 3b. When high voltage power is supplied to the electrohydraulic effect device, a high voltage strong electric field formed between the positive electrode 3a and the negative electrode 3b causes the liquid in the discharge channel to explode and generate a shock wave, thereby promoting the flow of liquid to achieve fruit and vegetable cleaning.

[0046] In an embodiment of the present invention, the power supply device may include a power supply circuit installed in a polyhedron structure and a power cord 2 installed outside the polyhedron structure and connected to the power supply circuit. It is understandable that the power supply device can be freely set according to the actual application needs for the power supply implementation, and the present invention does not specifically limit this. During specific use, high voltage power is supplied to the electrohydraulic effect device, and a high-voltage strong electric field is formed between the positive electrode 3a and the negative electrode 3b of the electrohydraulic effect device, which instantly releases huge energy in the discharge channel. The liquid passing through the discharge channel will quickly vaporize, expand and cause an explosion, thereby generating a shock wave. The huge shock wave will generate thrust on the washing water, so as to promote the flow of liquid to flush and wash fruits and vegetables. During the operation of the fruit and vegetable washing machine, the electrohydraulic effect device continues to produce electrohydraulic effect, continuously flushing the fruits and vegetables, thereby achieving a thorough cleaning effect.

[0047] In an embodiment of the present invention, the fruit and vegetable washing machine further comprises: each set of electrohydraulic effect devices installed on two mutually symmetrical side surfaces of the polyhedron structure operates simultaneously to prevent the placement of the fruit and vegetable washing machine from being shifted due to the shock wave generated by the electrohydraulic effect.

[0048] In one specific embodiment, the fruit and vegetable cleaning machine has a regular hexahedron structure, including four sides, each of which is symmetrical. The at least one set of electrohydraulic effect devices is comprised of two groups, each of which is mounted on the four sides of the regular hexahedron. In actual use, the electrohydraulic effect devices mounted on the mutually symmetrical front and rear sides of the regular hexahedron structure operate alternately with the electrohydraulic effect devices mounted on the mutually symmetrical left and right sides of the polyhedron structure to prevent overheating and damage to the electrohydraulic effect devices.

[0049] It is understandable that if only one side of the fruit and vegetable washing machine generates the electrohydraulic effect when it is working, the huge thrust generated by the single side will cause the placement of the fruit and vegetable washing machine to shift, making it impossible to keep the fruit and vegetable washing machine in the middle of the washing container, and thus unable to clean multiple surfaces of the fruits and vegetables, and thus unable to achieve a thorough cleaning effect, resulting in reduced cleaning efficiency. Figure 2As shown, in this embodiment, the fruit and vegetable washing machine adopts a symmetrical design. During each cleaning operation, the electrohydraulic effect device No. 1 31 and the electrohydraulic effect device No. 3 33 installed on the mutually symmetrical front and rear sides of the polyhedron structure work simultaneously as a group of electrohydraulic effect devices, or the electrohydraulic effect device No. 2 32 and the electrohydraulic effect device No. 4 34 installed on the mutually symmetrical left and right sides of the polyhedron structure work simultaneously as a group of electrohydraulic effect devices. In this case, the thrusts generated by the mutually symmetrical sides can offset each other, preventing the placement of the fruit and vegetable washing machine from being shifted due to the shock wave generated by the electrohydraulic effect.

[0050] It is understandable that since the electrohydraulic effect device will generate high temperatures when it is continuously working, and high temperatures can easily damage the electrohydraulic effect device after overheating, the working time of the electrohydraulic effect device cannot be too long and must work based on the set cleaning time. In this embodiment, during each cleaning, a group of electrohydraulic effect devices consisting of electrohydraulic effect device No. 1 31 and electrohydraulic effect device No. 3 33, which are installed on the front and rear sides of the regular hexahedron structure and are symmetrical to each other, and a group of electrohydraulic effect devices consisting of electrohydraulic effect device No. 2 32 and electrohydraulic effect device No. 4 34, which are installed on the left and right sides of the polyhedron structure and are symmetrical to each other, work in turn. This can prevent the electrohydraulic effect device from overheating and being damaged while also improving the efficiency of fruit and vegetable cleaning.

[0051] The present invention adopts the principle of liquid-electric effect to clean fruits and vegetables. Through discharge explosion between electrodes, a powerful shock wave is generated, which effectively removes dirty substances that strongly adhere to the surface of fruits and vegetables to thoroughly clean the fruits and vegetables. It is green and environmentally friendly and beneficial to human health.

[0052] Figure 3 FIG. 1 is a flow chart showing a control method for implementing fruit and vegetable cleaning based on the above-mentioned fruit and vegetable cleaning machine according to an embodiment of the present invention. Figure 3 As shown, the control method for a fruit and vegetable cleaning machine to clean fruits and vegetables provided in an embodiment of the present invention includes the following steps:

[0053] S11. In the pre-washing stage, the degree of contamination of the fruits and vegetables to be washed is determined based on the degree of contamination of the washing water.

[0054] In an embodiment of the present invention, the degree of contamination of fruits and vegetables to be washed is determined based on the degree of contamination of washing water, including: after the pre-washing stage, detecting a first current passing between the positive electrode and the negative electrode of the electrohydraulic effect device; comparing the first current with a preset current threshold to obtain a first difference obtained by the comparison, wherein the preset current threshold is the current detected between the positive electrode and the negative electrode when the electrohydraulic effect device is operating in a clean liquid environment; determining the threshold range to which the first difference belongs, and determining the degree of contamination of the fruits and vegetables to be washed based on the threshold range.

[0055] It is understood that the electrohydraulic effect device provided in the embodiments of the present invention uses a high-voltage power supply to form a pathway between two separate positive and negative electrodes immersed in wash water. Current flows between the positive and negative electrodes. Different levels of wash water contamination result in different resistance values, leading to different currents flowing between the positive and negative electrodes. Therefore, in this embodiment, the current flowing between the positive and negative electrodes of any electrohydraulic effect device in a fruit and vegetable washing machine can be used to characterize the contamination level of the wash water.

[0056] S12. Selecting a cleaning mode for the main cleaning phase that matches the current degree of dirtiness of the fruits and vegetables to be cleaned.

[0057] S13. When entering the main cleaning stage, each group of electrohydraulic effect devices is controlled to perform the fruit and vegetable cleaning operation according to the cleaning control parameters corresponding to the cleaning mode.

[0058] In an embodiment of the present invention, when entering the main cleaning stage, a second current passing between the positive electrode and the negative electrode of the liquid-electric effect device is detected; when entering the main cleaning stage and reaching the cleaning time set by the fruit and vegetable cleaning machine, a third current passing between the positive electrode and the negative electrode of the liquid-electric effect device is detected; the third current is compared with the second current to obtain a second difference obtained by the comparison; and the cleanliness condition of the fruits and vegetables to be cleaned is determined based on the second difference.

[0059] In an embodiment of the present invention, determining the cleanliness of the fruits and vegetables to be washed based on the second difference includes: judging whether the second difference is less than a preset difference threshold; if the second difference is less than the preset difference threshold, judging that the fruits and vegetables to be washed have been washed, and reminding the user that the fruit and vegetable washing is complete; if the second difference is greater than or equal to the preset difference threshold, judging that the fruits and vegetables to be washed are not washed, and reminding the user to change the water to perform the fruit and vegetable washing operation again.

[0060] In an embodiment of the present invention, the cleaning control parameters may include: cleaning time and / or cleaning intensity; when entering the main cleaning stage, controlling each group of electrohydraulic effect devices to perform fruit and vegetable cleaning operations according to the cleaning control parameters corresponding to the cleaning mode includes: obtaining the cleaning time and / or cleaning intensity corresponding to the cleaning mode; controlling each group of electrohydraulic effect devices installed on mutually symmetrical sides of the polyhedron structure to work alternately according to the cleaning time and / or cleaning intensity.

[0061] A control method for washing fruits and vegetables proposed in an embodiment of the present invention is based on the principle of liquid-electric effect. It uses discharge explosions between electrodes to generate powerful shock waves to flush and clean fruits and vegetables. In the pre-cleaning stage, a cleaning mode for the main cleaning stage that matches the current dirtiness of the fruits and vegetables to be cleaned is selected according to the dirtiness of the fruits and vegetables to be cleaned. When entering the main cleaning stage, each group of liquid-electric effect devices is controlled to perform the fruit and vegetable cleaning operation according to the cleaning control parameters corresponding to the cleaning mode. This achieves effective cleaning of dirt that strongly adheres to the surface of fruits and vegetables, thoroughly cleaning the fruits and vegetables and improving the user experience.

[0062] In the embodiment of the present invention, the cleaning time of the pre-cleaning stage can be set to 3-5 minutes. The cleaning time of the pre-cleaning stage can be freely set according to actual application needs, and the present invention does not make any specific limitation on this.

[0063] In an embodiment of the present invention, the cleaning time of the main cleaning stage can be set to 8-10 minutes. In actual application, the cleaning intensity corresponding to the cleaning mode of the main cleaning stage that matches the current degree of dirtiness of the fruits and vegetables to be cleaned can be selected, and the cleaning mode adopts the cleaning intensity corresponding to it to execute the corresponding cleaning time. For example, if the current degree of dirtiness is general dirtiness, the first cleaning mode can be selected to perform the cleaning operation for 10 minutes at the first level of cleaning intensity to achieve fruit and vegetable cleaning; if the current degree of dirtiness is very dirty, the third cleaning mode can be selected to perform the cleaning operation for 8 minutes at the third level of cleaning intensity to achieve fruit and vegetable cleaning. It should be noted that for the main cleaning stage, the fruit and vegetable cleaning machine performs the fruit and vegetable cleaning operation based on the cleaning intensity and / or cleaning time corresponding to the cleaning mode. The cleaning control strategy can be freely set according to the actual application needs, and the present invention does not make specific limitations on this.

[0064] Figure 4 The following is a flowchart showing a specific implementation of the control method for the fruit and vegetable cleaning machine proposed in an embodiment of the present invention. Figure 4 As shown, in a specific embodiment, the user places fruits and vegetables into a washing container, which can be a basin for washing fruits and vegetables, and then places the fruit and vegetable washing machine in the basin. After the fruits and vegetables and the fruit and vegetable washing machine are placed, the fruit and vegetable washing machine can be controlled to start up. When the fruit and vegetable washing machine is turned on, it first enters the pre-washing stage to pre-wash the fruits and vegetables. The cleaning time t1 of the pre-washing stage can be set to 5 minutes. Then, the dirtiness of the washing water is detected. Based on the dirtiness of the washing water, the dirtiness of the fruits and vegetables to be washed is determined. Based on the dirtiness of the fruits and vegetables to be washed, the cleaning intensity used in the cleaning mode of the main washing stage and the cleaning time corresponding to the cleaning mode are selected according to the dirtiness of the fruits and vegetables to be washed.

[0065] In an embodiment of the present invention, the degree of contamination of fruits and vegetables to be washed is determined based on the degree of contamination of washing water, specifically including: comparing the first current i0 passing between the positive electrode and the negative electrode of the electrohydraulic effect device after 5 minutes of detection with a preset current threshold i, and obtaining a first difference C1 obtained by the comparison; the preset current threshold i is empirical threshold data obtained through repeated experiments and stored in a database, and is the current detected between the positive electrode and the negative electrode of the device when the electrohydraulic effect device is working in a clean liquid environment; the preset current threshold i can be set to i=0.3, for example, when the first current i0=0.8, C1=i0-i=0.5; in this embodiment, the degree of contamination of fruits and vegetables to be washed is determined based on the threshold range to which the first difference belongs, so as to select the cleaning intensity adopted by the cleaning mode of the main washing stage that matches the current degree of contamination and the cleaning time corresponding to the cleaning mode according to the degree of contamination of the fruits and vegetables to be washed.

[0066] In an embodiment of the present invention, the threshold range to which the first difference belongs can be set as a first threshold range: 0 < difference C ≤ 0.3; a second threshold range: 0.3 < difference C ≤ 0.5; and a third threshold range: 0.5 < C. Different threshold ranges correspond to different levels of dirtiness of the fruits and vegetables to be cleaned: when the first difference C1 falls within the first threshold range, the degree of dirtiness of the fruits and vegetables can be determined to be moderate, and the first cleaning mode of the main cleaning stage, which matches moderate dirtiness, is selected. The first cleaning mode corresponds to a first level of cleaning intensity. When the first difference C1 falls within the second threshold range, the degree of dirtiness of the fruits and vegetables can be determined to be moderate, and the second cleaning mode of the main cleaning stage, which matches dirtiness, is selected. The second cleaning mode corresponds to a second level of cleaning intensity. When the first difference C1 falls within the third threshold range, the degree of dirtiness of the fruits and vegetables can be determined to be very dirty, and the third cleaning mode of the main cleaning stage, which matches very dirty, is selected. The third cleaning mode corresponds to a third level of cleaning intensity. The first level of cleaning intensity < the second level of cleaning intensity < the third level of cleaning intensity.

[0067] In the embodiment of the present invention, after selecting the cleaning mode of the main cleaning stage that matches the current degree of dirtiness, the main cleaning stage is entered, and the fruit and vegetable cleaning machine performs the fruit and vegetable cleaning operation based on the cleaning time and / or cleaning intensity corresponding to the cleaning mode. The cleaning time t2 of the main cleaning stage can be set to 10 minutes; when entering the main cleaning stage, the second current i passing between the positive electrode and the negative electrode of the liquid electro-effect device is detected. (n-1) When the cleaning time of the main cleaning stage reaches 10 minutes set by the fruit and vegetable cleaning machine, the water change operation is performed and the third current i passing between the positive electrode and the negative electrode of the liquid-electric effect device is detected. n ; The third current i n With the second current i (n-1)A comparison is performed to obtain a second difference value C2. If the second difference value C2 is greater than or equal to a preset difference threshold a, it can be determined that the fruits and vegetables to be washed are not clean, and the user is reminded to change the water and perform the fruit and vegetable washing operation again. If the second difference value C2 is less than the preset difference threshold a, it can be determined that the fruits and vegetables to be washed are clean and no more dirt is released, and the user is reminded that the fruit and vegetable washing operation is complete. The preset difference threshold a can be freely set according to actual application needs and is not specifically limited in the present invention.

[0068] The embodiment of the present invention adopts the principle of liquid-electric effect to clean fruits and vegetables. The huge shock wave generated by the discharge explosion between electrodes drives the water flow to clean the fruits and vegetables. At the same time, different cleaning intensities and / or cleaning times are adjusted according to the degree of dirtiness of the fruits and vegetables to be cleaned, effectively removing dirt and pollutants remaining on the surface of the fruits and vegetables, being environmentally friendly and healthy, and improving the user experience.

[0069] For simplicity of description, the method embodiments are described as a series of actions. However, those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because certain steps can be performed in other orders or simultaneously according to the embodiments of the present invention. Secondly, those skilled in the art should also be aware that the embodiments described in this specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.

[0070] Figure 5 FIG. 1 shows a structural block diagram of a control device for cleaning fruits and vegetables based on the above-mentioned fruit and vegetable cleaning machine according to an embodiment of the present invention. Figure 5 As shown, the control device for a fruit and vegetable washing machine according to an embodiment of the present invention includes: a determination module 201, a selection module 202, and a control module 203, wherein:

[0071] Determination module 201, for determining the degree of contamination of the fruits and vegetables to be washed according to the degree of contamination of the washing water during the pre-washing stage;

[0072] A selection module 202 is used to select a cleaning mode for the main cleaning phase that matches the current degree of dirtiness of the fruits and vegetables to be cleaned;

[0073] The control module 203 is used to control each group of electrohydraulic effect devices to perform the fruit and vegetable cleaning operation according to the cleaning control parameters corresponding to the cleaning mode when entering the main cleaning stage.

[0074] In the embodiment of the present invention, the determining module 201 includes:

[0075] The first detection unit is used to detect a first current passing between the positive electrode and the negative electrode of the electrohydraulic effect device after the pre-cleaning stage is completed; the first comparison unit is used to compare the first current with a preset current threshold value to obtain a first difference obtained by the comparison, wherein the preset current threshold value is the current detected between the positive electrode and the negative electrode when the electrohydraulic effect device is operating in a clean liquid environment; the determination unit is used to determine the threshold range to which the first difference belongs, and determine the degree of dirtiness of the fruits and vegetables to be cleaned based on the threshold range.

[0076] In the embodiment of the present invention, the control module 203 includes the following components (not shown in the drawings):

[0077] The second detection unit is used to detect the second current passing between the positive electrode and the negative electrode of the liquid-electric effect device when entering the main cleaning stage, and detect the third current passing between the positive electrode and the negative electrode of the liquid-electric effect device when entering the main cleaning stage and reaching the cleaning time set by the fruit and vegetable cleaning machine; the second comparison unit is used to compare the third current with the second current to obtain a second difference obtained by the comparison; and the control unit is used to determine the cleanliness of the fruits and vegetables to be cleaned based on the second difference.

[0078] In an embodiment of the present invention, the control module 203 is further configured to determine whether the second difference is less than a preset difference threshold; if the second difference is less than the preset difference threshold, it is determined that the fruits and vegetables to be washed have been cleaned, and the user is reminded that the fruit and vegetable washing is complete; if the second difference is greater than or equal to the preset difference threshold, it is determined that the fruits and vegetables to be washed are not cleaned, and the user is reminded to change the water to perform the fruit and vegetable washing operation again.

[0079] As for the device embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0080] In addition, the present invention also provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of the control method for implementing fruit and vegetable cleaning based on the fruit and vegetable cleaning machine as described above are implemented.

[0081] In this embodiment, if the control method for implementing fruit and vegetable cleaning based on a fruit and vegetable cleaning machine is implemented in the form of a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the present invention implements all or part of the processes in the above-mentioned embodiment method, and can also be completed by instructing the relevant hardware through a computer program. The computer program can be stored in a computer-readable storage medium, and when the computer program is executed by the processing device, it can implement the steps of the above-mentioned various method embodiments. Among them, the computer program includes computer program code, and the computer program code can be in source code form, object code form, executable file or some intermediate form, etc. The computer-readable medium may include: any entity or device that can carry the computer program code, recording medium, U disk, mobile hard disk, magnetic disk, optical disk, computer storage device, read-only memory device (ROM, Read-Only Memory), random access memory device (RAM, Random Access Memory), electrical carrier signal, telecommunication signal and software distribution medium, etc. It should be noted that the content contained in the computer-readable medium can be appropriately increased or decreased according to the requirements of legislation and patent practices in the jurisdiction. For example, in some jurisdictions, according to legislation and patent practices, computer-readable media do not include electrical carrier signals and telecommunication signals.

[0082] Embodiments of the present invention provide a fruit and vegetable washing machine and a control method, device, and storage medium for fruit and vegetable washing. The machine provides at least one set of electrohydraulic effect devices, supplies high voltage power to the electrohydraulic effect devices, and creates a high-voltage electric field between the positive and negative electrodes of the electrohydraulic effect devices, causing the liquid in the discharge channel to explode and generate shock waves, thereby promoting liquid flow and cleaning the fruits and vegetables. A cleaning mode for a main cleaning phase that matches the current level of dirtiness of the fruits and vegetables to be cleaned is selected. When the main cleaning phase begins, each set of electrohydraulic effect devices is controlled to perform the fruit and vegetable cleaning operation according to the cleaning control parameters corresponding to the cleaning mode. This effectively cleans strongly adhered dirt from the surfaces of the fruits and vegetables, thoroughly cleaning the fruits and vegetables and improving the user experience. Furthermore, by simultaneously operating each set of electrohydraulic effect devices, each of which is installed on mutually symmetrical sides of a polyhedron structure, the placement of the fruit and vegetable washing machine can be prevented from shifting due to shock waves generated by the electrohydraulic effect. By alternately operating two sets of electrohydraulic effect devices, each installed on the four sides of a regular hexahedron structure, overheating and damage to the electrohydraulic effect devices can also be prevented.
