Description

Technical Field

[0001] This invention relates to the field of kitchen sink cleaning technology, specifically to a water inlet control method, storage medium, and cleaning device for a washing apparatus. Background Technology

[0002] For Chinese kitchens, due to the abundance of ingredients, the need for cleaning fruits, vegetables, fish, and meat is very high. Currently, people mostly use sinks to clean these items, which is time-consuming and laborious. To solve this problem, the applicant's prior patent applications, CN119732601A ("A Fruit and Vegetable Washing Machine and Washing Method") and CN120061442A ("A Multifunctional Sink"), both disclose a sink cleaning structure. This structure involves a detachable / movable auxiliary tank within the sink body, equipped with a water and air intake system to introduce water and air into the auxiliary tank. This generates bubble water within the auxiliary tank, and the bursting of these bubbles removes dirt from the surface of the items to be washed.

[0003] The water volume in the auxiliary tank is also a key factor affecting the cleaning effect. Current technology typically uses turbine or impeller-type Hall effect flow sensors, combined with control of the water intake time, to control the water volume. However, these flow sensors are expensive, occupy a large space, and their placement in the pipeline affects the generation of micro-nano bubbles in the incoming water. Furthermore, during water intake, the water volume varies significantly under different inlet pressures for the same duration; insufficient water intake at low pressures and excessive water intake at high pressures cause overflow within the tank. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a water inlet control method for a cleaning device that can ensure that the water in the cleaning tank reaches a suitable level even without the need to set up a water volume detection device and when the water inlet pressure is uncertain.

[0005] The second technical problem to be solved by the present invention is to provide a computer-readable storage medium that stores computer instructions for causing a computer to execute the aforementioned water inlet control method of the cleaning device.

[0006] The third technical problem to be solved by the present invention is to provide a cleaning device that applies the aforementioned water inlet control method to the prior art.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a water intake method for a cleaning device, the cleaning device including a cleaning tank with an overflow hole at the top, a water intake channel and a drainage channel connected to the cleaning tank, a water intake valve for opening and closing the water intake channel is provided on the water intake channel, a drainage pump is provided on the drainage channel, the drainage channel located downstream of the drainage pump is suspended at a height, and the height of the overflow hole is higher than the suspension height of the drainage channel.

[0008] The water inlet control method of the cleaning device is to calculate the time reference value T1 = H / Q1 based on the water volume H corresponding to the target water level in the cleaning tank, where Q1 is the low water pressure inlet flow rate.

[0009] The water intake operation of the cleaning device includes a first water intake stage with continuous water intake and a second water intake stage with intermittent water intake. After the first water intake stage, the water volume in the cleaning tank is controlled to be limited to the water volume H1 corresponding to the hanging height of the drainage channel. After the second water intake stage, the water volume in the cleaning tank is controlled to be limited to the water volume H2 corresponding to the overflow hole height. When the sum of the continuous water intake time of the first water intake stage and the actual water intake time of the second stage reaches the time reference value T1, the water intake operation is completed.

[0010] As an improvement, the continuous water intake time of the first water intake stage is T2, where T2 = H1 / Q2, and Q2 is the high-pressure water intake flow rate.

[0011] As an improvement, the second water intake stage includes the following:

[0012] S1, control the opening of the inlet valve and the duration T3, T3=(H2-H1) / (Q2-Q3), Q3 is the overflow flow rate of the drainage channel, Q3<Q1;

[0013] S2. Calculate the current total water intake time T, T = T2 + k * T3, where k is the number of times step S1 is performed;

[0014] S3. Compare T with T1. If T≥T1, proceed to S5; otherwise, proceed to S4.

[0015] S4. Control the water inlet valve to close for a duration of T4, T4 = (H2 - H1) / Q3, and then return to step S1;

[0016] S5. Control the closing of the water inlet valve to complete the water intake of the cleaning device;

[0017] The water intake process is completed when the water intake time T2 of the first water intake stage and the actual water intake time Ts of the second water intake stage reach the time reference value T1.

[0018] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a computer-readable storage medium storing computer instructions, the computer instructions being used to cause a computer to perform the aforementioned cleaning machine working method.

[0019] The technical solution adopted by the present invention to solve the third technical problem mentioned above is as follows: a cleaning device, characterized in that: it includes a cleaning tank and a supply system, the supply system includes a water inlet channel and a water outlet channel connected to the cleaning tank, the water inlet channel is provided with a water inlet valve for opening and closing the water inlet channel, the water outlet channel is provided with a water outlet pump, the water outlet channel located downstream of the water outlet pump is suspended at a height, the cleaning tank is provided with an overflow hole, the height of the overflow hole is higher than the suspension height of the water outlet channel;

[0020] It also includes a controller and a memory. The controller is electrically connected to the water inlet valve, the drain pump, and the memory. The memory stores computer instructions, which are used to cause the controller to execute the aforementioned water inlet control method of the cleaning device.

[0021] To achieve bubble washing and enhance the cleaning effect, the supply system also includes an air intake channel connected to the cleaning tank, wherein the height of the air intake end of the air intake channel is higher than the height of the overflow hole.

[0022] To enhance the cleaning effect of the bubbles, the bottom of the cleaning tank is provided with an air inlet connected to the air inlet channel, and a water outlet connected to the water inlet pipe and the drain channel respectively.

[0023] Preferably, the washing tank includes an outer tank and an inner tank for accommodating food items to be washed, the inner tank being fitted inside the outer tank;

[0024] The bottom of the outer tank is provided with a recessed water inlet area, and the water outlet is opened at the bottom of the water inlet area;

[0025] The bottom of the inner tank is provided with a water passage hole that communicates with the outer tank. The bottom of the inner tank is also provided with an aeration channel and a bubble hole that can communicate with the air inlet channel. The air inlet is opened on the aeration channel, and the bubble hole is opened at the bottom of the inner tank corresponding to the aeration channel.

[0026] For ease of installation, it also includes a water tank, the cleaning tank being disposed inside the water tank, and the supply system being disposed on the outer wall of the water tank.

[0027] Alternatively, the cleaning tank may be fixedly or detachably disposed within the water tank.

[0028] Compared with existing technologies, the advantages of this invention are as follows: The water inlet control method of the cleaning device in this invention limits the total water inlet time by using a time reference value T1, and simultaneously controls the first and second water inlet stages. This effectively controls the amount of water entering the cleaning tank, maximizing water inlet while limiting the water level in the tank to within the hanging height range of the drainage channel. This not only minimizes overflow of the cleaning tank under high-pressure water inlet conditions, reducing the probability of device failure due to overflow, but also meets the cleaning water level requirements in the cleaning tank under low-pressure water inlet conditions, thereby ensuring the cleaning effect.

[0029] The cleaning device using this water inlet control method in this invention does not require additional detection devices for detecting water inlet volume or water level, resulting in relatively low cost and freeing up installation space, which is beneficial for component space layout design. Attached Figure Description

[0030] Figure 1 This is a flowchart of the water inlet control method for the cleaning device in an embodiment of the present invention.

[0031] Figure 2 This is a perspective view of the cleaning device in an embodiment of the present invention. Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] This invention relates to a cleaning device and a water inlet control method for the cleaning device. The cleaning device operates based on the water inlet control method to introduce water to a target water level, thereby achieving the cleaning operation.

[0034] like Figure 2 As shown, the cleaning device in this embodiment includes a cleaning tank 1, a supply system, a controller, and a memory.

[0035] The cleaning tank 1 is a tank structure, which includes an upward-opening tank body. Whether or not a cover is installed on the tank body is determined as needed. When a cover is installed, a closed cleaning tank 1 is formed; when no cover is installed, an open cleaning tank 1 is formed.

[0036] The cleaning device in this embodiment also includes a water tank 7, and the cleaning tank 1 is installed inside the water tank 7 in a fixed or detachable manner. Thus, the supply system can be installed on the outer wall of the water tank 7, thereby connecting with the cleaning tank 1. The supply system in this embodiment can supply water and air to the cleaning tank 1, and can also drain the cleaning tank 1.

[0037] In existing methods of combining the washing tank 1 with the sink 7 or a sink dishwasher, the washing tank 1 occupies the usable space of the sink 7. This embodiment provides a washing tank 1 that can be combined with or separated from the sink 7. When combined with the sink 7, it is an electric washing tank 1. When separated from the sink 7, it reverts to an independent large sink 7 to meet the different cleaning needs of users.

[0038] The washing tank 1 can be slidably installed in the water tank 7 along the side of the water tank 7. When the washing tank 1 is moved to a fixed position, it is connected to the supply system to realize the function of automatically washing food; when the washing tank 1 is moved to other positions, it is disconnected from the supply system and the washing tank 1 can be removed from the water tank 7 as a whole and used as an independent fruit and vegetable tank.

[0039] The supply system in this embodiment includes a water inlet channel 2 and a drainage channel 3 connected to the washing tank 1. The water inlet channel 2 is equipped with a water inlet valve 4 to control its opening and closing. During operation, the opening and closing of the water inlet channel 2 is achieved by controlling the opening and closing of the water inlet valve 4, thereby enabling water intake and stopping. The drainage channel 3 is equipped with a drainage pump 5, and the drainage channel 3 is suspended downstream of the drainage pump 5. During the washing process, water is first introduced by opening the water inlet valve 4. After water intake is complete, the fan connected to the air inlet end of the air inlet channel is turned on. Through aeration, the water in the washing tank 1 tumbles, cleaning the fruits and vegetables inside. After the washing process is completed, the drainage pump 5 is turned on to drain the water. Considering cost and installation space, the cleaning device in this embodiment does not have a drain valve. The water in the cleaning tank 1 is achieved by the hanging height of the drain channel 3 downstream of the drain pump 5. The highest liquid level in the cleaning tank 1 is determined by the hanging height of the drain channel 3. When the liquid level exceeds the hanging height of the drain channel 3, it will overflow from the drain channel 3. However, due to the obstruction of the drain pump 5 structure, the overflow flow rate of this drain channel 3 is usually less than the inlet flow rate.

[0040] To prevent water from backflowing into the air intake channel 6 and entering the fan in case of excessive water entering the cleaning tank 1 and causing the liquid level in the cleaning tank 1 to be too high, in this embodiment, an overflow hole 11 is provided on the cleaning tank 1. The height of the overflow hole 11 is higher than the hanging height of the drainage channel 3 and lower than the height of the air intake end connected to the fan in the air intake channel.

[0041] The controller is electrically connected to the inlet valve 4, the drain pump 5, and the memory. The controller can control the opening and closing of the inlet valve 4 and the drain pump 5. The memory stores computer instructions, which are used to make the controller execute the water inlet control method of the cleaning device described below.

[0042] When the cleaning tank 1 in this embodiment is installed and used in a user's home, the actual water supply pressure of each user's home is different, which will cause a certain deviation in the amount of water entering the tank within the same time. In order to solve this deviation problem, the water entering method of the cleaning device in this embodiment must ensure that the amount of water entering the tank at low water pressure meets the cleaning needs, and also ensure that the amount of water entering the tank at high water pressure does not overflow from the overflow hole 11 of the cleaning tank 1. Under normal conditions, the overflow hole 11 should not overflow, as overflow will cause the machine to leak. The overflow hole 11 is only a bottom-line structure to protect the fan from prolonged water ingress in extreme failure scenarios.

[0043] like Figure 1 As shown, the water intake method of the cleaning device in this embodiment is as follows: the time reference value T1 = H / Q1 is calculated based on the water volume H corresponding to the target water level in the cleaning tank 1, where Q1 is the low water pressure water intake flow rate. Using time T1 as the reference for water intake time ensures that even in the lowest water pressure application environment, the water level in the cleaning tank 1 can reach the target water level that meets the cleaning requirements.

[0044] However, in a high water pressure environment, for the same T1 water intake time, the water intake will be significantly more than that in a low water pressure environment. Since the overflow speed of the drainage channel 3 is far less than the water intake flow rate, the liquid level will rise rapidly, which may cause a lot of water to overflow from the overflow hole 11 in the tank into the water tank 7, which may cause trouble for users.

[0045] To accommodate the water intake requirements under both high and low pressure conditions, in this embodiment, the water intake time T1 is divided into two water intake stages. Specifically, when controlling the water intake, the water intake operation of the cleaning device includes a first water intake stage with continuous water intake and a second water intake stage with intermittent water intake.

[0046] To ensure that the final water level in the cleaning tank 1 does not exceed the height of the overflow hole 11, in this embodiment, the water volume in the cleaning tank 1 after the first water inlet stage is limited to the water volume H1 corresponding to the hanging height of the drain channel 3. This water inlet stage enables rapid water inlet and minimizes the water inlet time. After the second water inlet stage, the water volume in the cleaning tank 1 is limited to the water volume H2 corresponding to the height of the overflow hole 11. That is, if the water volume exceeds the water volume corresponding to the hanging height of the drain channel 3, the excess water can also be discharged through the drain channel 3. It is only necessary to ensure that the water level rise caused by the difference between the water inlet flow rate and the drainage flow rate does not exceed the height of the overflow hole 11.

[0047] When the sum of the continuous water intake time of the first water intake stage and the actual water intake time of the second stage reaches the time reference value T1, the water intake work is completed.

[0048] Specifically, in this embodiment, the water inlet control for the first water inlet stage and the second water receiving stage is as follows.

[0049] The continuous water inlet time for the first water inlet stage is T2, where T2 = H1 / Q2, and Q2 is the high-pressure water inlet flow rate. This water inlet time ensures that even under high water pressure, after this water inlet stage, the water volume in the cleaning tank 1 will only reach H1. If the user's water pressure is lower than the high-pressure water supply, the water volume in the cleaning tank 1 will inevitably be lower than H1. This water inlet control during the first water inlet stage ensures that the water level in the cleaning tank 1 is limited to the hanging height range of the drain channel 3.

[0050] After the first stage of water intake is completed, the second stage of water intake will begin.

[0051] The second water intake stage includes steps S1 to S5.

[0052] S1. Control the opening of the inlet valve 4 for a duration of T3, where T3 = H2 - H1 / Q2 - Q3, and Q3 is the overflow flow rate of the drainage channel 3, Q3 < Q1. H2 - H1 is the maximum water volume from the overflow flow rate H1 of the drainage channel 3 to the maximum water volume without overflowing from the overflow hole 11. During the time period T3, the water volume is greater than the overflow flow rate of the drainage channel 3, but less than the overflow height of the overflow hole 11. At this time, water is entering while water is also being drained through the drainage channel 3. Q2 - Q3 is the dynamic inlet flow rate at this time.

[0053] S2. Calculate the current total water intake time T, T = T2 + k * T3, where k is the number of times step S1 is performed.

[0054] S3. Compare T with T1. If T ≥ T1, proceed to S5; otherwise, proceed to S4. This step is mainly for the user to determine whether the total water intake time meets the requirements of the low-pressure state, avoiding insufficient water intake when operating under low water pressure. At the same time, to avoid the water intake after dynamic water flow rate is higher than the water volume corresponding to overflow hole 11 when operating under high water pressure, step S4 is required.

[0055] S4. Control the water inlet valve 4 to close for a duration of T4, T4 = H2 - H1 / Q3. At this time, water inlet is paused. If the water pressure is high, the liquid level will be higher than the overflow drainage level of the drainage channel 3. During the time T4, the overflow drainage will continue through the drainage channel 3. After T4 ends, the water volume in the cleaning tank 1 is H2. Then, another water inlet time T3 is entered, and then the process returns to step S1.

[0056] S5. Control the closing of the water inlet valve 4 to complete the water intake of the cleaning device.

[0057] The water intake method of the cleaning device in this invention ensures sufficient water intake at low water pressure. At high water pressure, the water intake time and pause time are controlled by opening and closing the water inlet valve 4. Excess water overflows into the tank through the drainage channel 3, preventing excessive water from overflowing directly through the overflow hole 11 in the cleaning tank 1. Through the control of the water intake logic, the significant differences in water usage patterns at the user end can be minimized.

[0058] The water inlet control method of the cleaning device in this invention limits the total water inlet time by a time reference value T1, and effectively controls the amount of water entering the cleaning tank 1 by controlling the first and second water inlet stages. While maximizing water inlet, the water level in the inlet tank 7 is limited to the hanging height range of the drainage channel 3. This method minimizes the risk of overflow in the cleaning tank 1 under high-pressure water inlet conditions, reducing the probability of device malfunction due to overflow, and also meets the cleaning water level requirements in the cleaning tank 1 under low-pressure water inlet conditions, thereby ensuring the cleaning effect.

[0059] The cleaning device using this water inlet control method in this invention does not require additional detection devices for detecting water inlet volume or water level, resulting in relatively low cost and freeing up installation space, which is beneficial for component space layout design.
