A cleaning method for a fruit and vegetable washing machine

Abstract

This invention relates to a cleaning method for a fruit and vegetable washing machine. The fruit and vegetable washing machine includes a housing. The invention has a water inlet component on the side of the housing and an air inlet component at the bottom of the housing. An air pressure sensor and a wind speed sensor are installed on the air inlet component. During the water and air intake process, as the water volume increases, in order to prevent water from flowing back into the air inlet component, it is necessary to balance the wind speed and the pressure generated by the water intake. The air intake wind speed is in a real-time dynamic adjustment process. This dynamic adjustment process is used to determine the water intake volume, and water is automatically replenished and adjusted according to the number of fruits and vegetables to be washed. During the washing process, regardless of the quantity of items to be washed, the wind speed used to create turbulence is always adapted to the corresponding washing water volume, thereby maintaining a stable degree of turbulence and improving the cleaning effect.

Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable washing machine technology, specifically to a washing method for a fruit and vegetable washing machine. Background Technology

[0002] Currently, fruit and vegetable washing machines mainly rely on turbulent flow within the fruit and vegetable tank to clean fruits and vegetables.

[0003] The applicant's prior patent ZL201910623660.8, "A Fruit and Vegetable Washing Machine," discloses a structure comprising a housing and a spray arm. The housing is hollow, forming a washing chamber. The spray arm is disposed in the washing chamber and has a main flow channel extending laterally in the washing chamber and multiple secondary flow channels extending outward from both sides of the main flow channel. Several water outlet holes, which are connected to the main flow channel and the secondary flow channels, are arranged at intervals on the side wall of the spray arm. Each water outlet hole is evenly distributed at various points on the cross-section of the washing chamber. An impeller assembly capable of pumping water into the spray arm at high speed is provided at the bottom of the housing.

[0004] The above solution distributes the water outlets evenly throughout the washing chamber to enhance water flow turbulence and ensure that the water flows evenly over the surface of fruits and vegetables, thus improving the cleaning effect. However, the water intake is constant during washing and cannot be automatically adjusted according to the amount of fruits and vegetables to be washed, resulting in the cleaning effect being affected by changes in the quantity of fruits and vegetables being washed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cleaning method for a fruit and vegetable cleaning machine that can automatically adjust the water intake according to the amount of fruit and vegetables to be washed and always maintain a stable turbulence level, thereby improving the cleaning effect, in light of the current state of the technology.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A cleaning method for a fruit and vegetable cleaning machine, the fruit and vegetable cleaning machine includes a box, a water inlet component is provided on the side of the box, and an air inlet component is provided at the bottom of the box. The air inlet component is provided with an air outlet that can disperse the gas to various parts of the bottom of the box to generate turbulence. The air inlet component is provided with a pressure sensor that can detect the air pressure in real time and a wind speed sensor that can detect the wind speed.

[0008] The cleaning method includes the following steps:

[0009] (1) Water intake stage

[0010] The water inlet valve of the water inlet assembly is opened, and the air inlet assembly is also opened. During the water inlet process, the wind speed sensor and air pressure sensor record the wind speed and air pressure values ​​in real time and feed them back to the controller. The controller adjusts the wind speed in real time to prevent water in the chamber from flowing back into the air inlet assembly. That is, the output wind speed of the air inlet assembly is dynamically adjusted during the water inlet process. The controller determines the water inlet volume based on the parameters fed back by the air pressure sensor. When the water inlet volume reaches the set value, the water inlet valve is closed. At this time, the air inlet assembly continues to blow air into the chamber at the current wind speed.

[0011] (2) Water replenishment stage

[0012] Place the fruits and vegetables to be cleaned into the box. During this process, the output wind speed of the air intake component is dynamically adjusted. The controller determines the amount of fruits and vegetables to be cleaned based on the change value of the parameter detected by the air pressure sensor and controls the water inlet valve to add the corresponding amount of washing water.

[0013] (3) Cleaning stage

[0014] Controlling the power of the air intake component ensures that the airflow is maintained at a level that creates stable turbulence within the chamber, which in turn causes the fruits and vegetables to tumble and be cleaned.

[0015] Preferably, during the water intake and replenishment stages, when the output wind speed of the air intake component is dynamically adjusted, the target value of the wind speed sensor is greater than 0 and less than 0.01 m / s. Using these parameters, water flow can be prevented from flowing back into the air intake component, the wind speed and the pressure generated by the incoming water can be balanced in real time, and stable turbulence can be maintained.

[0016] Preferably, a drainage assembly is provided at the bottom of the housing. During the drainage process, the output wind speed of the air intake assembly is dynamically adjusted to ensure that the air intake pipe is always full of gas but the wind speed tends to be 0. As the amount of water in the housing continues to decrease, the air pressure value monitored by the air pressure sensor also gradually decreases. When the air pressure monitoring reaches zero, it means that the water in the housing has been drained. This invention determines whether the drainage is complete by balancing the wind speed and the water pressure in the housing in real time. It has a simple structure and is easy to operate.

[0017] Preferably, a drain outlet is provided in an important part of the bottom wall of the box, and the drainage component is located at the outer bottom of the box and connected to the drain outlet.

[0018] Preferably, the air intake assembly includes an air guide pipe assembly, an air intake pipe, and an air pump. The air guide pipe assembly is located at the bottom of the housing and has multiple air outlets. The air intake pipe is located at the bottom of the housing and its outlet end passes through the bottom of the housing and is connected to the air guide pipe assembly. The air intake end of the air intake pipe is connected to the air pump. The air pressure sensor and the wind speed sensor are both located at the air intake pipe.

[0019] Preferably, the air guide pipe assembly includes multiple first air guide sections extending laterally at the bottom of the housing and multiple second air guide sections extending vertically. The first and second air guide sections intersect and communicate with each other, jointly covering the bottom of the housing. The upper surfaces of both the first and second air guide sections have several spaced-apart air outlets. This structure ensures that the gas is evenly dispersed throughout the housing after being input, maintaining stable turbulence at all points.

[0020] Preferably, the fruit and vegetable washing machine of the present invention further includes a fruit and vegetable washing basket. The box body is a first water tank with an open top. The fruit and vegetable washing basket can be detachably placed in the box body, and the top edge of the fruit and vegetable washing basket is provided with a support edge for supporting it on the top edge of the first water tank. Before washing, the fruits and vegetables can be placed in the fruit and vegetable washing basket, and then the fruit and vegetable washing basket can be placed into the box body as a whole, which is convenient to use.

[0021] Preferably, the bottom and side walls of the fruit and vegetable washing basket are hollow structures. The bottom wall of the fruit and vegetable washing basket is arranged close to the air intake component below it, and the bottom wall of the fruit and vegetable washing basket constitutes a dispersion structure for dispersing the gas output from the air intake component in all directions. This structure helps to maintain turbulent stability throughout the box.

[0022] Preferably, a second water tank with a larger volume than the first water tank is provided next to the first water tank. With the support edge of the fruit and vegetable washing basket resting on the top edge of the second water tank, the fruit and vegetable washing basket constitutes a drain basket. Using this structure, after washing, the fruit and vegetable washing basket can be placed in the second water tank to drain. When washing fruits and vegetables is not required, the fruit and vegetable washing basket can also be used as an independent drain basket to meet more consumer needs.

[0023] Compared with the prior art, the advantages of the present invention are as follows: The present invention has a water inlet component on the side of the box and an air inlet component at the bottom of the box. The air inlet component is equipped with an air pressure sensor and a wind speed sensor. During the water and air intake process, as the water volume increases, in order to prevent water from flowing back into the air intake component, it is necessary to balance the wind speed and the pressure generated by the water intake. The air intake wind speed is in a real-time dynamic adjustment process. The water intake volume is determined by this dynamic adjustment process, and water is automatically replenished and adjusted according to the number of fruits and vegetables to be washed. During the washing process, no matter how many items are to be washed, the wind speed used to form turbulence is always adapted to the corresponding washing water volume, thereby maintaining a stable degree of turbulence and improving the washing effect.

[0027] Figure 4 This is a schematic diagram of the structure of the fruit and vegetable washing basket in an embodiment of the present invention. Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1 As shown in Figure 4, the cleaning method of the fruit and vegetable cleaning machine in this embodiment includes a box 1. A water inlet component 2 is provided on the side of the box 1, and an air inlet component 3 is provided at the bottom of the box 1. The air inlet component 3 is provided with an air outlet 301 that can disperse the gas to various parts of the bottom of the box 1 to generate turbulence. The air inlet component 3 is provided with an air pressure sensor 10 that can detect the air pressure in real time and an air speed sensor 20 that can detect the wind speed.

[0030] The cleaning method includes the following steps:

[0031] (1) Water intake stage

[0032] The water inlet valve of the water inlet assembly 2 is opened, and the air inlet assembly 3 is opened at the same time. During the water inlet process, the wind speed sensor 20 and the air pressure sensor 10 record the wind speed and air pressure values ​​in real time and feed them back to the controller. The wind speed is adjusted in real time to prevent water in the box 1 from flowing back into the air inlet assembly 3. That is, the output wind speed of the air inlet assembly 3 is in a dynamic adjustment process during the water inlet process. The controller determines the water inlet volume based on the parameters fed back by the air pressure sensor. When the water inlet volume reaches the set value, the water inlet valve is closed. At this time, the air inlet assembly 3 continues to blow air into the box 1 at the current wind speed.

[0033] By maintaining the target value of the wind speed sensor between 0 and 0.01 m / s (to prevent water from flowing back into the air inlet pipe and causing the monitoring capability to fail), the power value of the air pump is adjusted in real time. That is, when the wind speed is detected to be greater than 0.01 m / s, the power is slightly reduced, and when the wind speed is detected to be 0, the power is slightly increased to keep the water stable in the cavity and prevent backflow.

[0034] (2) Water replenishment stage

[0035] Place the fruits and vegetables to be cleaned into the box 1. During this process, the output wind speed of the air intake component 3 is dynamically adjusted. The controller determines the amount of fruits and vegetables to be cleaned based on the change value of the parameter detected by the air pressure sensor 10, and controls the water inlet valve to add the corresponding amount of washing water.

[0036] Because the amount of fruits and vegetables varies, the water level rises at different rates. Based on a preset correlation, the water level is determined by the pressure sensor readings, allowing for the measurement of different amounts of fruits and vegetables. By analyzing the preset relationship between water volume and fruit / vegetable quantity, it can be determined whether there is an excess of fruits and vegetables, and water can be added quantitatively to ensure effective cleaning.

[0037] (3) Cleaning stage

[0038] Controlling the power of the air intake component 3 ensures that the wind speed is maintained at a level that allows the output air volume to form a stable turbulence in the housing 1. This turbulence causes the fruits and vegetables to tumble and be cleaned.

[0039] During the water intake and replenishment phases, the output wind speed of the air intake assembly 3 is dynamically adjusted, with the target value of the wind speed sensor 20 being greater than 0 and less than 0.01 m / s. By using these parameters, water flow can be prevented from flowing back into the air intake assembly 3, the wind speed and the pressure generated by the incoming water can be balanced in real time, and stable turbulence can be maintained.

[0040] A drainage assembly 4 is installed at the bottom of the housing 1. During the drainage process, the output wind speed of the air intake assembly 3 is dynamically adjusted to ensure that the air intake pipe 32 is always full of gas but the wind speed tends to be 0. As the amount of water in the housing 1 continues to decrease, the air pressure value monitored by the air pressure sensor 10 also gradually decreases. When the air pressure monitoring reaches zero, it means that the water in the housing 1 has been drained. This embodiment determines whether the drainage is complete by balancing the wind speed and the water pressure in the housing 1 in real time. The structure is simple and the operation is convenient.

[0041] A drain outlet 11 is provided in an important part of the bottom wall of the box 1, and the drainage component 4 is located at the bottom of the box 1 and is connected to the drain outlet 11.

[0042] The air intake assembly 3 includes an air guide pipe group 31, an air intake pipe 32, and an air pump (not shown in the figure). The air guide pipe group 31 is located at the bottom of the box 1 and has multiple air outlets 301. The air intake pipe 32 is located at the bottom of the box 1 and its air outlet passes through the bottom of the box 1 and is connected to the air guide pipe group 31. The air inlet end of the air intake pipe 32 is connected to the air pump. The air pressure sensor 10 and the wind speed sensor 20 are both located at the air intake pipe 32.

[0043] The air guide tube assembly 31 includes multiple first air guide sections 311 extending laterally at the bottom of the housing 1 and multiple second air guide sections 312 extending vertically. The first air guide sections and second air guide sections 312 are interconnected and jointly cover the bottom of the housing 1. The upper surfaces of the first air guide sections 311 and second air guide sections 312 are provided with several spaced-apart air outlets 301. This structure ensures that the gas is evenly dispersed throughout the housing 1 after being input, maintaining stable turbulence at all points.

[0044] The fruit and vegetable washing machine in this embodiment also includes a fruit and vegetable washing basket 5. The housing 1 is a first water tank with an open top. The fruit and vegetable washing basket 5 can be detachably placed in the housing 1, and the top edge of the fruit and vegetable washing basket 5 is provided with a support edge 51 for supporting it on the top edge of the first water tank. Before washing, the fruits and vegetables can be placed in the fruit and vegetable washing basket 5, and then the fruit and vegetable washing basket 5 can be placed into the housing 1 as a whole, which is convenient to use.

[0045] The bottom and side walls of the fruit and vegetable washing basket 5 are both hollow structures. The bottom wall of the fruit and vegetable washing basket 5 is arranged close to the air intake component 3 below it, and the bottom wall of the fruit and vegetable washing basket 5 forms a dispersion structure for dispersing the gas output from the air intake component 3 in all directions. This structure helps to maintain the stability of turbulence at all parts of the box 1.

[0046] A second water tank 6, larger in volume than the first water tank, is provided next to the first water tank. With the support edge of the fruit and vegetable washing basket 5 resting on the top edge of the second water tank 6, the fruit and vegetable washing basket 5 forms a draining basket. Using this structure, after washing, the fruit and vegetable washing basket 5 can be placed in the second water tank 6 to drain. When washing fruits and vegetables is not required, the fruit and vegetable washing basket 5 can also be used as an independent draining basket to meet more consumer needs.

[0047] In the cleaning process of this embodiment, after water enters the chamber, water pressure is generated due to the water depth. At this point, air needs to overcome this pressure to flow smoothly from the vent. During the water intake process, a wind speed sensor keeps the air pump power at a critical value where the wind speed is zero. The air pressure sensor reading corresponds to the water level depth, allowing for real-time detection of the water intake. This method allows for different amounts of water to be added for cleaning, soaking, and other operations according to preset values. Furthermore, after water intake, monitoring the water level change when the user places fruits and vegetables into the chamber allows for estimation of the amount of produce, determining whether additional water is needed or adjusting the cleaning power accordingly.

[0048] In this embodiment, a water inlet assembly 2 is provided on the side of the box 1, and an air inlet assembly 3 is provided at the bottom of the box 1. An air pressure sensor 10 and a wind speed sensor 20 are provided on the air inlet assembly 3. During the water and air intake process, as the water volume increases, in order to prevent water from flowing back into the air inlet assembly 3, it is necessary to balance the wind speed and the pressure generated by the water intake. The air intake wind speed is in a real-time dynamic adjustment process. The water intake volume is determined by this dynamic adjustment process, and water is automatically replenished and adjusted according to the number of fruits and vegetables to be washed. During the washing process, no matter how many items are to be washed, the wind speed used to form turbulence is always adapted to the corresponding washing water volume, thereby maintaining a stable degree of turbulence and improving the washing effect.

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.
