Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, specifically to a control method for cleaning a sink. Background Technology

[0002] Traditional washing sinks typically only have a basin, and when washing food, plates or dishes are needed to hold the cleaned food, making them inconvenient to use.

[0003] To address this issue, Chinese patent application CN200420072388.8, entitled "A Kitchen Sink," provides a kitchen sink comprising a sink body with at least one trough. Horizontal continuous slide rails are provided on the front and rear walls of the trough. A tray is mounted on the slide rails, with rollers located at the four lower corners of the tray. When washing food, there is no need to use separate plates or dishes; food can be placed directly on the tray, which is easy to move and remove, making it very convenient to use.

[0004] However, the aforementioned tray is only used as a storage tray and cannot automatically drain water, nor does it have a cleaning or purification function. In addition, most modern electrified sinks now occupy one of the sinks as a fixed sink for cleaning and purifying food, which affects the usable space of the sink and does not conform to the current trend of large single-sink sinks for a better user experience.

[0005] In addition, currently, users mostly remove purines from food by blanching it with cooking tools to reduce the purine content. For example, Chinese patent application number CN201910911856.7, entitled "A Control Method, Device, Appliance and Storage Medium for a Household Appliance," provides a control method, device, appliance and storage medium for a household appliance. The method includes: after obtaining a first operation on a first button, activating the blanching function; heating the liquid inside the container to decompose the purine substances in the food within the liquid. The above-mentioned blanching method for removing purines involves steps such as filling water, heating, emptying water, and cleaning, requiring the user to move back and forth between the sink and the cooking area, which is cumbersome and inefficient. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a method for controlling a washing sink that can reduce the purine content in food, is simple to operate, and does not affect the taste and nutrition of the food, in light of the current state of the technology.

[0007] The second technical problem to be solved by the present invention is to provide a control method for a cleaning water tank that facilitates water intake and user access to the tank.

[0008] The third technical problem to be solved by the present invention is to provide a control method for a cleaning water tank that can facilitate the cleaning and purification of food without affecting the use of the tank.

[0009] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a control method for a cleaning water tank, characterized in that: the cleaning water tank includes a tank body, a tray body installed on the tank body, a micro-nano bubble water supply device and a gas supply device;

[0010] The cleaning tank has a first working mode. After the cleaning tank enters the first working mode, the control system first supplies micro-nano bubble water to the tray body through the micro-nano bubble water supply device to soak the food. Then, it blows air into the tray body through the gas supply device. Then, it drains the water from the tray body and repeats the water intake, air blowing and drainage operation until the turbidity value or purine content of the water in the tray body reaches the set value.

[0011] To further address the second technical problem mentioned above, the cleaning tank also has a second working mode. When the cleaning tank enters the second working mode, the control system supplies micro-nano bubble water into the tank through a micro-nano bubble water supply device. At this time, the user can collect the micro-nano bubble water through a container.

[0012] To further address the third technical problem mentioned above, the tray body is detachably installed in the tank, the tank having a cleaning position, and the rear side wall of the tray body having a water inlet and an air inlet.

[0013] Furthermore, it also includes a docking component, which includes...

[0014] The main body is installed on the rear side wall of the tank.

[0015] A water inlet pipe and an air inlet pipe, extending in the front-to-back direction and movably mounted on the main body; and

[0018] In the first state, the water inlet pipe is retracted into the front end face of the main body and detached from the water inlet hole, and the air inlet pipe is retracted into the front end face of the main body and detached from the air inlet hole.

[0019] In the second state, the tray body is in the cleaning position, the water inlet pipe extends out of the front end face of the body and is inserted into the water inlet hole, and the air inlet pipe extends out of the front end face of the body and is inserted into the air inlet hole.

[0020] In the third state, the tray body is removed from the cleaning position, the water inlet pipe extends out of the front end face of the main body and into the tank, and the air inlet pipe extends out of the front end face of the main body and into the tank.

[0021] In order to utilize the existing drainage pipes of the tank for drainage and avoid setting up additional drainage pipes for the pallet body, the rear side wall of the pallet body has drainage holes;

[0022] The docking assembly also includes a sealing post fixed relative to the water inlet pipe, the sealing post extending in the front-back direction and being movable back-and-forth on the main body;

[0023] In the first state, the sealing post is retracted into the front end face of the main body and disengaged from the drain hole, so that the drain hole is opened;

[0024] In the second state, the sealing post extends beyond the front end face of the main body and is inserted into the drain hole to close the drain hole;

[0025] In the third state, the sealing post extends beyond the front end face of the main body and into the groove.

[0026] To facilitate the installation of the water inlet pipe, air inlet pipe, and sealing column, the docking assembly also includes a movable seat, which can be movably installed on the main body. The water inlet pipe, air inlet pipe, and sealing column are fixed relative to the movable seat, and the power output end of the drive device is driven and connected to the movable seat.

[0028] The lead screw nut is installed on the movable seat;

[0029] A lead screw, extending in the front-to-back direction, is threadedly connected to the lead screw nut; and

[0030] A lead screw motor is used to drive the lead screw to rotate around its own axis.

[0031] To facilitate the installation of the main body on the groove, the main body includes a base and a panel installed on the front side of the base. The rear side wall of the groove has an installation opening, the edge of which is sandwiched between the base and the panel.

[0032] To ensure the aesthetics of the cleaning tank when it is not in operation, in the first state, the front ends of the water inlet pipe, air inlet pipe, and sealing column are flush with the front end of the panel.

[0033] In order to speed up drainage while avoiding contamination of other areas inside the tank, a drain outlet is provided on the bottom wall of the tank, and a recessed drainage channel is provided on the bottom wall inside the tank, which is connected to the drain outlet.

[0035] To simplify the structure, the water inlet and air inlet share the same channel, and the water inlet pipe and air inlet pipe share the same pipe.

[0036] To facilitate the uniform entry of air into the tray body, an aeration plate is provided inside the tray body, and the air inlet end of the aeration plate is connected to the air inlet hole.

[0037] In order to enable the entry of the first working mode and the second working mode and improve the user experience, the tank body is equipped with a power button, a food type selection button, a cleaning water button and a start button, as well as a position sensor for monitoring whether the tray body is in the cleaning position.

[0082] Compared with the prior art, the advantages of the present invention are as follows:

[0083] (1) By setting up a micro-nano bubble water supply device and a gas supply device, in the first working mode, the micro-nano bubble water supply device supplies micro-nano bubble water to the tray body to soak the food to remove purines, and the gas supply device blows air into the tray body to roll the food to remove purines and clean the dirt on the surface of the food. The combination of the two can reduce the purine content in the food and is simple to operate.

[0084] In addition, the continuous cleaning process continues until the turbidity or purine content of the water in the tray reaches the set value, ensuring that the food is cleaned without affecting its taste and nutrition.

[0085] (2) In the second working mode, micro-nano bubble water is supplied to the tank through the micro-nano bubble water supply device, which facilitates water intake into the tank and water collection by the user.

[0086] (3) By setting water inlet and air inlet on the tray body, and driving the water inlet pipe and air inlet pipe to move back and forth to connect with it by a drive device, the cleaning tank has at least three states: In the first state, the water inlet pipe retracts and disengages from the water inlet, and the air inlet pipe retracts and disengages from the air inlet. At this time, the tray body can be removed from the tank without affecting the use of the tank. In the second state, the tray body is in the cleaning position, the water inlet pipe extends out and is inserted into the water inlet, and the air inlet pipe extends out and is inserted into the air inlet. At this time, a water inlet path is formed between the water inlet pipe and the water inlet, and an air inlet path is formed between the air inlet pipe and the air inlet. At the same time, the tray body is fixed to form a fixed cleaning chamber, which is convenient for cleaning and purifying food. In the third state, the tray body is removed from the cleaning position, and the water inlet pipe and air inlet pipe extend out and are inserted into the tank. At this time, it is convenient for the tank to be filled with water and for the user to collect water. Attached Figure Description

[0103] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0104] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0105] like Figures 1 to 13 The image shows a preferred embodiment of the cleaning tank of the present invention. The cleaning tank includes a tank body 1, a tray assembly 2, a docking assembly 3, a micro / nano bubble water supply device 4, and a gas supply device 5.

[0106] The tank 1 has support bars 11 extending in the left and right directions on both the front and rear side walls; the right rear side wall of the tank 1 has an installation port 12; the left bottom wall of the tank 1 has a drain outlet 13; the rear of the bottom wall inside the tank 1 has a recessed drainage channel 14 connected to the drain outlet 13; a control board 15 is installed on the rear side of the tank 1, which has a power button, a food type selection button, a cleaning water button, and a start button; a Hall sensor 16 is installed at the location of the installation port 12 on the outer side wall of the tank 1 as a position sensor.

[0107] The pallet assembly 2 includes a pallet body 21, a drain basket 22, a cover plate 23, and an aeration plate 24.

[0108] Specifically, the top edge of the tray body 21 extends outward to form a first folded edge 211. The first folded edges 211 on the front and rear sides of the tray body 21 form first sliding strips 2111, which correspond to the support strips 11. Each first sliding strip 2111 can slide left and right on the corresponding support strip 11, thereby realizing the left and right sliding and detachable installation of the tray body 21 in the tank 1. In this embodiment, the tank 1 has a cleaning position. When the tray body 21 moves to the right to its limit position, the tray body 21 is in the cleaning position. The outer edge of the first folded edge 211 is partially bent upward to form a U-shaped stop edge 2112 with the opening facing left. The rear side wall of the tray body 21 has a water inlet hole 212. In this embodiment, the air inlet 212 and the air inlet 213 share the same channel, and the drain holes 214 are arranged at intervals below the water inlet 212. A magnet 215 is installed on the rear side of the bottom of the tray body 21. When the tray body 21 is in the cleaning position, the magnet 215 is within the sensing range of the Hall sensor 16. When the tray body 21 is out of the cleaning position, the magnet 215 is outside the sensing range of the Hall sensor 16, so that the Hall sensor 16 can detect whether the tray body 21 is in the cleaning position. In addition, when the tray body 21 is placed in the tank 1, the outlet end of the drain hole 214 is located directly above the drain channel 14.

[0109] The bottom and side walls of the drain basket 22 are provided with a plurality of mesh holes 220 arranged in a matrix pattern; the top edge of the drain basket 22 extends outward to form a second folded edge 221, and the second folded edges 221 on the front and rear sides of the drain basket 22 form second sliding strips 2211, which correspond to the aforementioned support strips 11; the drain basket 22 has two usage states:

[0110] In the first state of use, such as Figure 12As shown, the second fold 221 rests above the first fold 211, thereby enabling the drain basket 22 to be detachably installed inside the tray body 21. At this time, the drain basket 22 forms a fruit and vegetable basket.

[0111] In the second usage state, such as Figure 13 As shown, each second slide bar 2211 can slide left and right on the corresponding support bar 11, thereby realizing the detachable installation of the drain basket 22 in the tank 1.

[0112] Cover plate 23 has two usage states:

[0113] In the first state of use, such as Figure 1 As shown, the edge of the cover plate 23 rests on the top of the second folded edge 221 (or it can rest directly on the top of the first folded edge 211), thereby realizing the detachable installation of the cover plate 23 on the pallet body 21. At this time, the cover plate 23 covers the top opening of the pallet body 21, thereby sealing the inner cavity of the pallet body 21. The stop edge 2112 is limited to the outer periphery of the cover plate 23 to prevent the cover plate 23 from easily shifting.

[0114] In the second usage state, such as Figure 12 As shown, the edges of the front and rear sides of the cover plate 23 can slide left and right and rest on the corresponding support bars 11, thereby realizing the detachable installation of the tray 23 on the trough 1. At this time, the cover plate 23 forms an anvil.

[0115] The aeration plate 24 is located at the bottom of the inner cavity of the tray body 21, and the air inlet end of the aeration plate 24 is connected to the air inlet hole 213.

[0116] The docking assembly 3 includes a main body 31, a movable seat 32, a water inlet pipe 33, an air inlet pipe 34, a sealing column 35, and a driving device 36.

[0117] Specifically, the main body 31 is installed at the aforementioned mounting opening 12, including a base 311 and a panel 312 installed on the front side of the base 311, with the edge of the aforementioned mounting opening 12 sandwiched between the base 311 and the panel 312.

[0118] The movable seat 32 can be mounted on the base 311 in a movable manner, moving back and forth.

[0119] The water inlet pipe 33 and the air inlet pipe 34 share the same pipe, which extends in the front-to-back direction and is integral with the aforementioned movable seat 32.

[0120] The sealing posts 35 are spaced apart below the water inlet pipe 33. The sealing posts 35 extend in the front-to-back direction and are integral with the movable seat 32.

[0121] The drive device 36 includes a lead screw nut 361, a lead screw 362, and a lead screw motor 363. The lead screw nut 361 is mounted on a movable seat 32. The lead screw 362 extends in the front-back direction, and both ends of the lead screw 362 are rotatably connected to the base 311. The lead screw nut 361 is threadedly connected to the outer circumference of the lead screw 362. The power output end of the lead screw motor 363 is connected to the lead screw 362 to drive the lead screw 362 to rotate around its own axis. When the lead screw motor 363 is started, the lead screw 362 is driven to rotate. Since the lead screw nut 361 is threadedly connected to the lead screw 362, the lead screw nut 361 drives the water inlet pipe 33, the air inlet pipe 34, and the sealing column 35 to move back and forth through the movable seat 32.

[0122] Driven by the drive unit 36 ​​and in conjunction with the installation of the tray body 21, the above-mentioned cleaning water tank has at least three states:

[0123] In the first state, such as Figure 9 As shown, the water inlet pipe 33 is retracted into the front end face of the main body 31 and disengaged from the water inlet hole 212 (i.e., the air inlet pipe 34 is retracted into the front end face of the main body 31 and disengaged from the air inlet hole 213), and the sealing column 35 is retracted into the front end face of the main body 31 and disengaged from the drain hole 214, so that the drain hole 214 is opened; at this time, the front end faces of the water inlet pipe 33, the air inlet pipe 34 and the sealing column 35 are flush with the front end face of the panel 312, which can ensure the aesthetics of the cleaning water tank when it is not in operation.

[0124] In the second state, such as Figure 10 As shown, the tray body 21 is in the cleaning position, the water inlet pipe 33 extends out of the front end face of the body 31 and is inserted into the water inlet hole 212 (that is, the air inlet pipe 34 extends out of the front end face of the body 31 and is inserted into the air inlet hole 213), and the sealing column 35 extends out of the front end face of the body 31 and is inserted into the drain hole 214 to close the drain hole 214.

[0125] In the third state, such as Figure 11 As shown, the tray body 21 is removed from the cleaning position, the water inlet pipe 33 extends out of the front end face of the body 31 and into the tank 1 (that is, the air inlet pipe 34 extends out of the front end face of the body 31 and into the tank 1), and the sealing column 35 extends out of the front end face of the body 31 and into the tank 1.

[0126] The micro-nano bubble water supply device 4 is used to supply micro-nano bubble water to the water inlet pipe 33. In this embodiment, the micro-nano bubble water supply device 4 includes a micro-nano bubble generator 41 and a water inlet valve 42. Specifically, the water inlet end of the micro-nano bubble generator 41 is connected to an external tap water pipeline through a water supply pipe 411, and the water outlet end of the micro-nano bubble generator 41 is connected to the inlet end of the water inlet pipe 33 through a pipeline; the water inlet valve 42 is installed on the water supply pipe 411 and is used to control the opening and closing of the water supply pipe 411.

[0127] The gas supply device 5 is used to supply atmospheric air to the air inlet pipe 34. In this embodiment, the gas supply device 5 includes a fan 51 and a gas delivery pipe 52. Specifically, the intake end of the fan 51 is connected to the outside atmosphere; the inlet end of the gas delivery pipe 52 is connected to the exhaust end of the fan 51, and the outlet end of the gas delivery pipe 52 is connected to the inlet end of the air inlet pipe 34.

[0128] In addition, the aforementioned micro-nano bubble water supply device 4 and gas supply device 5 are both installed on the rear side wall of the tank 1, and the outer sides of the micro-nano bubble water supply device 4 and gas supply device 5 are covered with protective covers 17.

[0129] In addition, the tank body 1 is equipped with a weight sensor for monitoring the weight of the food in the tray body 21. The tray body 21 is equipped with a liquid level sensor for monitoring the liquid level in the tray body 21, a turbidity sensor for monitoring the turbidity value of the water in the tray body 21, and a purine sensor for monitoring the purine content of the water in the tray body 21. A flow sensor for monitoring the flow rate of the water inlet pipe 33 is installed on the water inlet pipe 33.

[0130] The working principle of this embodiment is as follows:

[0131] (1) When it is not necessary to use micro-nano bubble water combined with large bubble tumbling for purine removal cleaning of food and there is no need to collect micro-nano bubble water, such as Figure 9 As shown, the cleaning tank is in the first state, the water inlet pipe 33 is retracted into the front end face of the main body 31 and disengaged from the water inlet hole 212 (that is, the air inlet pipe 34 is retracted into the front end face of the main body 31 and disengaged from the air inlet hole 213), and the sealing column 35 is retracted into the front end face of the main body 31 and disengaged from the drain hole 214, so that the drain hole 214 is opened. At this time, the tray assembly 2 can slide freely in the tank 1 in the left and right directions, and can also be taken out from the tank 1 without affecting the use of the tank 1.

[0132] (2) When it is necessary to use micro-nano bubble water combined with large bubble tumbling for purine removal cleaning of food, the tray assembly 2 can be moved to the right to its extreme position (i.e., the cleaning position) first. Then, the drive device 36 is activated to drive the water inlet pipe 33, air inlet pipe 34, and sealing column 35 forward until the water inlet pipe 33 extends beyond the front end face of the main body 31 and is inserted into the water inlet hole 212 (i.e., the air inlet pipe 34 extends beyond the front end face of the main body 31 and is inserted into the air inlet hole 213), and the sealing column 35 extends beyond the front end face of the main body 31 and is inserted into the drain hole 214, so that the drain hole 214 is closed. At this time, if Figure 10As shown, the cleaning tank is in the second state. A water inlet pipe 33 corresponding to the water inlet hole 212 forms a water inlet path with the water inlet hole 212 (i.e., an air inlet pipe 34 corresponding to the air inlet hole 213 forms an air inlet path with the air inlet hole 213). A sealing post 35 corresponding to the drain hole 214 blocks the drain hole 214. Simultaneously, the tray assembly 2 is fixed to form a fixed cleaning chamber. The user can activate the micro-nano bubble water supply device 4 to supply micro-nano bubble water to the water inlet pipe 33 (controlled by the water inlet valve 42). Automatic water inlet is controlled. Tap water passes through water pipe 411 and micro-nano bubble generator 41 to generate micro-nano bubble water, which is then supplied to water inlet pipe 33. This allows the micro-nano bubble water to enter the tray body 21 for soaking food to remove purines. At the same time, the gas supply device 5 is activated to supply air to air inlet pipe 34 (fan 51 controls automatic air intake, and air is supplied to air inlet pipe 34 through air pipe 52). This allows large bubbles to enter the tray body 21 to tumble the food to remove purines and to clean the surface dirt of the food.

[0133] After cleaning, simply turn off the micro-nano bubble water supply device 4 and the gas supply device 5, and start the drive device 36 to drive the water inlet pipe 33, air inlet pipe 34 and sealing column 35 to move to the first state. The wastewater in the tray body 21 can be discharged through the drain hole 214 and collected into the drain outlet 13 through the drain channel 14.

[0134] It should be noted that by using micro-nano bubble water combined with large bubble tumbling technology, the tray body 21 and drain basket 22 and other parts can also be intelligently self-cleaned after the food is washed, and dirt can be automatically discharged without manual cleaning.

[0135] (3) When it is necessary to collect micro-nano bubble water, the tray assembly 2 can be moved to the left or removed from the tank 1 to remove it from the cleaning position. Then, the drive device 36 is activated to drive the water inlet pipe 33, air inlet pipe 34, and sealing column 35 forward until the water inlet pipe 33 extends beyond the front end face of the main body 31 and into the tank 1 (i.e., the air inlet pipe 34 extends beyond the front end face of the main body 31 and into the tank 1), and the sealing column 35 extends beyond the front end face of the main body 31 and into the tank 1. At this time, if Figure 10 As shown, the washing tank is in the third state. The user can start the micro-nano bubble water supply device 4 to deliver micro-nano bubble water to the water inlet pipe 33, and collect the micro-nano bubble water separately through the water cup for functions such as soaking, washing and sterilizing small amounts of food.

[0136] In addition, the entire tray assembly 2 is feature-rich:

[0137] First, in addition to being fixed to form a fixed cleaning chamber in conjunction with the docking component 3, the tray body 21 can also be used as a regular tray or removed from the tank 1 without affecting the usable space of the tank 1, thus improving the space utilization efficiency of the tank 1.

[0138] Secondly, the drain basket 22 can be installed inside the tray body 21 as a fruit and vegetable basket, or installed inside the trough 1 as a regular drain basket.

[0139] Third, the cover plate 23 can be placed on the top opening of the tray body 21 to seal the inner cavity of the tray body 21, or it can be installed on the trough 1 and used as a cutting board.

[0140] like Figures 14 to 16 As shown, the present invention also provides a control method for the above-mentioned cleaning water tank.

[0141] The cleaning tank in this embodiment has a first working mode and a second working mode:

[0142] After the washing tank enters the first working mode, the control system first supplies micro-nano bubble water to the tray body 21 through the micro-nano bubble water supply device 4 to soak the food. Then, it blows air into the tray body 21 through the gas supply device 5, and then drains the water in the tray body 21. The water inlet, air inlet and drain operation are repeated until the turbidity value or purine content of the water in the tray body 21 reaches the set value.

[0143] After the cleaning tank enters the second working mode, the control system supplies micro-nano bubble water to the tank 1 through the micro-nano bubble water supply device 4. At this time, the user can collect the micro-nano bubble water through the container.

[0144] In this embodiment, the first and second working modes are specifically entered through the following methods:

[0145] S101: The user first presses the power button, then presses the food type selection button or the cleaning water button, and finally presses the start button to enter S102.

[0146] S102. The position sensor monitors whether the tray body 21 is in the cleaning position. If yes, proceed to S103; otherwise, proceed to S107.

[0147] S103. The control system determines whether the user has pressed the cleaning water button. If yes, proceed to S104; otherwise, proceed to S105.

[0148] S104. Issue an alarm to remind the user to take the tray body 21, and return to S102;

[0149] S105. The control system determines whether the user has pressed the food type selection button. If yes, proceed to S106; otherwise, proceed to S111.

[0150] S106, the driving device 36 drives the water inlet pipe 33, the air inlet pipe 34 and the sealing column 35 to be inserted into the corresponding water inlet hole 212, air inlet hole 213 and drain hole 214, and enters the first working mode;

[0151] S107. The control system determines whether the user has pressed the food type selection button. If yes, proceed to S108; otherwise, proceed to S109.

[0152] S108. Issue an alarm to remind the user to place the tray body 21, then return to S102;

[0153] S109. The control system determines whether the user has pressed the cleaning water button. If yes, proceed to S110; otherwise, proceed to S111.

[0154] S110, the drive device 36 drives the water inlet pipe 33, the air inlet pipe 34 and the sealing column 35 to extend into the tank 1 and enter the second working mode;

[0155] S111, End.

[0156] In this embodiment, the first working mode described above is implemented through the following method:

[0157] S201, Start the first working mode, then enter S202;

[0158] S202: The weight sensor monitors whether the weight of the food in the tray body 21 has reached the set value. If yes, proceed to S203; otherwise, proceed to S204.

[0160] S204. Calculate the maximum number of water inlet and outlet cycles C, single soaking time T1, and single aeration time T2 based on the selected ingredient type and the monitored ingredient weight, and proceed to S205.

[0161] S205, Open inlet valve 42 to proceed to S206;

[0162] S206. The liquid level sensor monitors whether the liquid level in the tray body 21 has reached the set value. If yes, proceed to S207; otherwise, return to S205.

[0163] S207. Close the inlet valve 42. The flow sensor calculates the inlet water volume D. The control system timer starts timing. Proceed to S208.

[0164] S208. Determine whether the timer has reached the single soaking time T1. If yes, proceed to S209. If no, return to S207.

[0165] S209: The control system timer stops timing, calculates and sets the power W1 based on the water inflow D, and then proceeds to S210;

[0166] S210, Start the blower 51 and adjust the blower power to the set power W1 (since the water intake is controlled by the liquid level, the water intake D is different for different volumes of food, so the blower power needs to be adjusted according to the water intake D to ensure the aeration effect), control the system timer to start timing, and enter S211.

[0167] S211. The turbidity sensor monitors whether the turbidity value of the water in the tray body 21 is less than the set value. If yes, proceed to S212; if no, proceed to S217. (Under normal circumstances, as the number of washing cycles increases, the dirt on the food will decrease, and the turbidity value of the water in the tray body 21 will continue to decrease. When the turbidity value increases, it means that the food has been over-washed, and small debris begins to peel off from the surface of the food. At this time, washing should be stopped, otherwise the food will be over-washed and thus affect the appearance and taste of the food.)

[0168] S212. Determine if the timer has reached the single-inflation time T2. If yes, proceed to S213. If no, return to S210.

[0169] S213. The purine sensor monitors whether the purine content of the water in the tray body 21 is greater than the set value. If yes, proceed to S214; if no, proceed to S217. (Under normal circumstances, as the number of washing cycles increases, the dirt on the food will decrease, and the purine content P of the water in the tray body 21 will continue to decrease. When the purine content of the water is less than or equal to the set value, it means that the purines that can be released from the food have been released, and there is no point in continuing to wash it.)

[0170] S214, shut down the fan 51, drive device 36 drives water inlet pipe 33, air inlet pipe 34 and sealing column 35 to disengage from the corresponding water inlet hole 212, air inlet hole 213 and drain hole 214, and enter S215;

[0171] S215. The liquid level sensor monitors whether the liquid level in the tray body 21 is greater than the set value. If yes, return to S214; if no, proceed to S216.

[0172] S216. Determine whether the number of times the inlet valve 42 has been opened has reached the upper limit C of the number of times the water inlet and outlet have been opened. If yes, proceed to S219; otherwise, return to S205.

[0173] S217, shut down the fan 51, drive the drive device 36 to drive the water inlet pipe 33, air inlet pipe 34 and sealing column 35 to disengage from the corresponding water inlet hole 212, air inlet hole 213 and drain hole 214, and enter S218;

[0174] S218. The liquid level sensor monitors whether the liquid level in the tray body 21 is greater than the set value. If yes, return to S217; if no, proceed to S219.

[0175] S219. Issue an alarm to remind the user that the food washing is complete, then end.

[0176] In the above control method, the optimal washing sequence for different ingredients is matched according to the type and weight of the ingredients through program settings (controlling parameters such as washing time, number of water inlet and outlet cycles, and bubble intensity) to ensure that the ingredients are cleaned without affecting their taste and nutrition.

[0177] In this embodiment, the second working mode is specifically implemented through the following method:

[0178] S301, Start the second working mode, enter S302;

[0179] S302. Open the water inlet valve 42. At this time, the user can use a container to collect micro-nano bubble water from the outlet end of the water inlet pipe 33 and enter S303.

[0180] S303. Determine if the user clicks the cleaning water button again. If yes, proceed to S304; otherwise, return to S302.

[0181] S304. Close the water inlet valve 42. The drive device 36 drives the water inlet pipe 33, air inlet pipe 34 and sealing column 35 to retract inward, and the process ends.
