Description
Technical Field
The invention belongs to the field of kitchen cleaning products, and particularly relates to a water adding method of a fruit and vegetable machine.
Background
Fruits and vegetables are necessities of people's life, and in the fruit and vegetable planting process, pesticides are generally sprayed to prevent plant diseases and insect pests, so pesticide residues can be left, and equipment for detecting pesticide residues in ordinary families is not available, and if the fruits and vegetables are eaten without being cleaned, the health of eaters can be affected, and dust or soil carried on the fruits and vegetables also need to be cleaned. The fruit and vegetable machine can meet and clean the fruit and vegetable, and can remove the use requirement of pesticide residues.
The fruit and vegetable cleaning machine is a small household appliance for kitchen, and is mainly used for cleaning, disinfecting and removing pesticide residues on the surfaces of fruits and vegetables. The fruit and vegetable machine is basically provided with a cleaning basket, an air pump, an ozone generator and other structures, and the automatic water inlet fruit and vegetable machine further comprises a water level sensor, a water inlet valve and a water discharge valve. The fruits and vegetables are placed in the cleaning basket, and the clear water submerges the fruits and vegetables.
However, the fruit and vegetable machine in the prior art has the following problems when automatically feeding water:
1. if residual water exists, whether the water is completely discharged cannot be judged; 2. if the water leakage condition exists, whether the water leakage exists or not cannot be judged; 3. when water is continuously added during water inlet, the float shakes greatly, so that the water adding accuracy is poor.
Disclosure of Invention
The invention aims to solve the technical problem of providing a water adding method of a fruit and vegetable machine, which can drain residual water in time, judge the water leakage condition and have better water adding accuracy.
The object of the present invention is to provide: a water adding method of a fruit and vegetable machine comprises the following steps:
1) after the machine is started, the water level is detected, and the water level in the tank is judged according to the water level sensor:
if the water level is not at the preset lowest water level, opening a drain valve for draining, closing the drain valve when the water level reaches the lowest water level, and opening a water inlet valve for feeding water; after the drain valve T1 is opened, the water level is kept unchanged, and the system gives an alarm;
if the water level is at the preset lowest water level, opening the water inlet valve to feed water;
2) after the time T2, closing the water inlet valve, detecting the water level in the tank:
if the water level is still at the lowest water level, the water inlet valve is opened again for water inlet, the operation is repeated for C times, the water level is still at the lowest water level, and the system gives an alarm;
if the water level is not at the lowest water level, judging whether the preset water level is reached;
if the water level is preset, water inlet is finished;
if the water level is not at the preset water level, opening the water inlet valve for water inlet, closing the water inlet valve after the water inlet time is T3, and detecting the water level in the tank again; if the water level is not up to the preset water level, repeating the last water inlet action until the water level reaches the preset water level.
Compared with the prior art, the invention has the advantages that:
1. because the water level detection is carried out before water enters, the pollution of residual water in the last washing to the washing can be effectively prevented, the cleaning effect of the articles is ensured, and the condition of cross contamination is avoided; meanwhile, whether drainage is normal or not is self-checked, the use stability of the whole mechanism when a user can normally use the drainage device is guaranteed, and the use experience of the user is improved.
2. Because at the in-process of intaking, set up the judgement logic to guarantee that the user is in the use, even if nobody watch when watching, can not appear full water or leak the condition of still working, and then guarantee stability and the reliability of using.
3. Because the water adding is in a multi-section mode, the water inlet valve is closed firstly, and then the water level is detected, the stability of the floater is good, so that the water adding accuracy is ensured, and the articles to be washed are completely immersed in the water when the subsequent air pump works, so that the cleaning effect is ensured.
As an improvement, after the water inlet valve is closed and T7 is delayed, the water level in the tank is detected; then the time delay back can eliminate the inslot water body and rock and cause the inaccurate problem of detection to guarantee the stability that the water level detected, and then make the efficiency and the accuracy of intaking, make user's use impression better.
Preferably, the T7 is 1-4 seconds; after the arrangement, the whole water inlet time is relatively short on the premise of ensuring the detection accuracy.
As an improvement, in the step 1), if the water level is not at the preset lowest water level, the drain valve is opened for draining, and when the water level reaches the lowest water level, the water inlet valve is opened for 2-4 seconds, and then water is introduced to close the drain valve; after the treatment, the pollutants that the residual water was left over can be washed away to the intaking to the cleanliness of water is better when guaranteeing later stage water conservation, can prevent cross contamination's the condition effectively, guarantees to treat the cleaning performance of wasing the article.
Preferably, the T1 is 1-3 seconds; within the time range, the water level detection can quickly reflect the water level condition, and the system can make correct judgment in time.
More preferably, T1 is 2 seconds.
Preferably, the time T2 is 8-22 seconds; in the time range, water can be fed into the water tank for 1-2 times generally in the low water level, and water can be fed into the water tank for 2-4 times generally in the medium-high water level, so that the water feeding efficiency is improved; meanwhile, the abnormity can be judged quickly, and prompt is given to a user in time.
More preferably, T2 is 16 seconds.
Preferably, the time T3 is 6-10 seconds; then this time horizon, the later stage fine setting water yield of being convenient for the accuracy of intaking is better, when guaranteeing the cleaning performance, the using water wisely.
Preferably, the time period T4 is 2-4 minutes, the time period T5 is 3-5 minutes, and the time period T6 is 4-6 minutes; after the total water adding time is set, the excessive water adding can be prevented, a user can be reminded of the water leakage or water seepage condition of the tank body, the equipment can be overhauled in time, and the stability and the reliability of the equipment in use are ensured.
As an improvement, the system is also provided with a low water level area, a middle water level area and a high water level area, and whether the water inlet is abnormal or not is judged according to the total water inlet time of the preset low water level area, the preset middle water level area and the preset high water level area:
(1) when the preset water level value falls into the low water level area, if the total water inlet time exceeds T4, water inlet is abnormal, and the system gives an alarm;
(2) when the preset water level value falls into the middle water level area, if the total water inlet time exceeds T5, water inlet is abnormal, and the system gives an alarm;
(3) when the preset water level value falls into the high water level area, if the total water inlet time exceeds T6, the water inlet is abnormal, and the system gives an alarm. Then because in the water inlet process, the control of the total water inlet time is set, and the total water inlet time of different water levels is set, thereby ensuring the reliability of water inlet and effectively preventing the problem of excessive water inlet.
