Description

Technical Field

[0001] The invention relates to the technical field of fruit and vegetable cleaning machines, and in particular to a cleaning method of a fruit and vegetable cleaning machine. Background Art

[0002] At present, the cleaning of fruits and vegetables by fruit and vegetable washing machines is mainly achieved by turbulence in the fruit and vegetable tank.

[0003] The applicant's prior patent ZL201910623660.8 "A fruit and vegetable washing machine" discloses a structure including a box body and a spray arm. The interior of the box body is hollow to form a washing chamber. The spray arm is arranged in the washing chamber. The spray arm has a main channel extending laterally in the washing chamber and a plurality of secondary channels extending outward from both sides of the main channel. A plurality of water outlet holes respectively connected to the main channel and the secondary channels are arranged at intervals on the side wall of the spray arm. The water outlet holes are evenly distributed at various locations in the cross-section of the washing chamber. An impeller assembly that can pump water into the spray arm at high speed is provided at the bottom of the box body.

[0004] The above scheme makes the water outlet holes evenly distributed in various places of the washing chamber to enhance the turbulence of the water flow and make the water flow evenly flow over the surface of fruits and vegetables to improve the washing 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 a certain influence on the washing effect due to the change in the amount of fruits and vegetables to be 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 which can automatically adjust the water intake according to the number of fruits and vegetables to be cleaned and always maintain a stable turbulence level to improve the cleaning effect in view of the current status of the prior art.

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

[0008] The cleaning method comprises the following steps:

[0009] (1) Water inlet stage

[0010] The water inlet valve of the water inlet assembly is opened, and the air inlet assembly is opened at the same time. During the water inlet process, the wind speed sensor and the air pressure sensor record the wind speed value and the air pressure value in real time and feed them back to the controller, and the wind speed is adjusted in real time to prevent the water in the box from flowing back into the air inlet assembly, that is, the output wind speed of the air inlet assembly is in a dynamic adjustment process during the water inlet process; the controller determines the water inlet amount according to the parameters fed back by the pressure sensor, and when the water inlet amount reaches the set value, the water inlet valve is closed. At this time, the air inlet assembly continues to maintain the current wind speed to blow air into the box;

[0013] (3) Cleaning stage

[0014] The power of the air intake assembly is controlled so that the wind speed is maintained at the output air volume, which can form a stable turbulence in the box. The turbulence drives the fruits and vegetables to roll for cleaning.

[0015] Preferably, during the water inlet stage and the water replenishment stage, when the wind speed output by the air inlet assembly is dynamically adjusted, the target value of the wind speed sensor is greater than 0 and less than 0.01 m / s.

During the drainage process, the output wind speed of the air intake component is in a dynamic adjustment process to ensure that the air intake pipeline is always full of gas but the wind speed tends to 0. As the amount of water in the box continues to decrease, the air pressure value monitored by the air pressure sensor also gradually decreases. When the air pressure monitoring is zero, the water in the box has been drained. The present invention determines whether the drainage is completely drained by balancing the wind speed and the pressure of the water in the box in real time. It has a simple structure and is easy to operate.

[0017] Preferably, a drain port is provided at an important position of the bottom wall of the box body, and the drain assembly is arranged at the outer bottom of the box body and is connected to the drain port.

[0028] The present invention is further described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 4 As shown, the cleaning method of the fruit and vegetable cleaning machine of this embodiment, the fruit and vegetable cleaning machine comprises a box body 1, a water inlet assembly 2 is arranged on the side of the box body 1, an air inlet assembly 3 is arranged at the bottom of the box body 1, the air inlet assembly 3 is provided with an air outlet 301 that can disperse the gas to various places at the bottom of the box body 1 to generate turbulence, and the air inlet assembly 3 is provided with an air pressure sensor 10 that can detect the air pressure of the intake air in real time and a wind speed sensor 20 that detects the wind speed;

[0030] The cleaning method comprises the following steps:

[0031] (1) Water inlet 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 value and the air pressure value in real time and feed them back to the controller, and adjust the wind speed in real time to prevent the 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 amount according to the parameters fed back by the pressure sensor, and when the water inlet amount reaches the set value, the water inlet valve is closed. At this time, the air inlet assembly 3 continues to maintain the current wind speed to blow air into the box 1;

[0033] By maintaining the target value of the wind speed sensor between 0-0.01m / s (to prevent water in the box from flowing back into the air inlet pipe, causing the monitoring capability to fail), real-time feedback is used to adjust the power value of the air pump. That is, when the wind speed is detected to be greater than 0.01m / s, the power is slightly reduced. 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] The fruits and vegetables to be washed are placed in the box 1. During this process, the output wind speed of the air intake assembly 3 is dynamically adjusted. The controller determines the amount of fruits and vegetables to be washed according to 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] Due to the different amount of fruits and vegetables, the degree of water level rise is different. According to the preset corresponding relationship, the different water levels can be fed back by the pressure sensor to measure the different amounts of fruits and vegetables. According to the preset relationship between the amount of water and the amount of fruits and vegetables, it is judged whether the amount of fruits and vegetables is too much, and quantitative water is added to ensure the cleaning effect.

[0037] (3) Cleaning stage

[0038] The power of the air intake assembly 3 is controlled so that the wind speed is maintained at a level at which the output air volume can form a stable turbulence in the box 1, and the turbulence drives the fruits and vegetables to roll for cleaning.

[0039] During the water inlet stage and water replenishment stage, when the wind speed output by the air inlet assembly 3 is dynamically adjusted, the target value of the wind speed sensor 20 is greater than 0 and less than 0.01 m / s. The above parameters can be used to prevent water from flowing back into the air inlet assembly 3, balance the wind speed and the pressure generated by the water inlet in real time, and maintain stable turbulence.

[0040] A drainage component 4 is provided at the bottom of the box 1. During the drainage process, the output wind speed of the air intake component 3 is in a dynamic adjustment process to ensure that the air intake pipe 32 is always full of gas but the wind speed tends to 0. As the amount of water in the box 1 continues to decrease, the air pressure value monitored by the air pressure sensor 10 also gradually decreases. When the air pressure monitoring is zero, the water in the box 1 has been drained. This embodiment determines whether the water is completely drained by balancing the wind speed and the pressure of the water in the box 1 in real time, and has a simple structure and is easy to operate.

[0041] A drainage port 11 is provided at an important position of the bottom wall of the box body 1 , and the drainage assembly 4 is disposed at the outer bottom of the box body 1 and communicated with the drainage port 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 arranged at the bottom of the box body 1 and has multiple air outlet holes 301. The air intake pipe 32 is arranged at the bottom of the box body 1 and the air outlet end passes through the bottom of the box body 1 and is connected to the air guide pipe group 31. The air intake 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 arranged at the air intake pipe 32.

[0043] The air guide pipe group 31 includes a plurality of first air guide parts 311 extending horizontally at the bottom of the box body 1 and a plurality of second air guide parts 312 extending vertically. The first air guide parts and the second air guide parts 312 are cross-connected and cover the bottom of the box body 1 together. The upper surfaces of the first air guide parts 311 and the second air guide parts 312 are provided with a plurality of air outlet holes 301 arranged at intervals. The above structure is adopted so that the gas can be evenly dispersed everywhere after being input into the box body 1, and the turbulence stability at each place is maintained.

[0044] The fruit and vegetable washing machine of this embodiment further 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 a support edge 51 is provided on the top edge of the fruit and vegetable washing basket 5 to support the fruit and vegetable washing basket 5 on the top edge of the first water tank. Before washing, the fruit and vegetable washing basket 5 can be placed in the fruit and vegetable washing basket 5 first, and then the fruit and vegetable washing basket 5 can be put into the housing 1 as a whole, which is convenient to use.

[0045] The bottom wall and side walls of the fruit and vegetable washing basket 5 are both hollow structures, and the bottom wall of the fruit and vegetable washing basket 5 is arranged close to the air intake assembly 3 below it, and the bottom wall of the fruit and vegetable washing basket 5 constitutes a dispersion structure for dispersing the gas output by the air intake assembly 3 in all directions. This structure is conducive to maintaining turbulence stability at various locations of the box 1.

[0046] A second water tank 6 having a larger volume than the first water tank is arranged beside the first water tank, and the supporting edge of the fruit and vegetable washing basket 5 is placed on the top edge of the second water tank 6, so that the fruit and vegetable washing basket 5 forms a drain basket. With the above structure, the fruit and vegetable washing basket 5 can be placed in the second water tank 6 to drain after washing. When the fruit and vegetables do not need to be washed, the fruit and vegetable washing basket 5 can also be used as an independent drain basket to meet more needs of consumers.

[0047] During the cleaning process of this embodiment, after water enters the box, water pressure will be generated due to a certain water depth. At this time, ventilation into the box needs to resist this part of the pressure so that the gas can smoothly surge up from the air outlet. During the water intake process, the wind speed sensor is used to control the power of the air pump at the critical value of zero wind speed. At this time, the value of the air pressure sensor can correspond to the water level depth at this time, and the water intake can be detected in real time. Through this method, different amounts of water can be taken in according to the preset value for cleaning, soaking and other operations; at the same time, after the water is taken in, when the user places fruits and vegetables in the box, the change in the water level can be monitored to estimate the amount of fruits and vegetables, so as to determine whether it is necessary to replenish water or match different intensities of cleaning power.

[0048] In this embodiment, a water inlet component 2 is arranged on the side of the box body 1, an air inlet component 3 is arranged on the bottom of the box body 1, and an air pressure sensor 10 and a wind speed sensor 20 are arranged on the air inlet component 3. During the water inlet and air inlet process, as the amount of water increases, in order to maintain the water flow from backflowing into the air inlet component 3, it is necessary to balance the wind speed and the pressure generated by the water inlet. The air inlet wind speed is in a real-time dynamic adjustment process. The dynamic adjustment process is used to judge the water inlet amount, and the water inlet amount is automatically replenished and adjusted according to the number of fruits and vegetables to be washed. During the washing process, no matter how many objects to be washed are there, the wind speed used to form turbulence is always adapted to the corresponding amount of washing water, thereby always maintaining a stable degree of turbulence and improving the washing effect.
