Fruit and vegetable cleaning machine

Abstract

The invention relates to a fruit and vegetable cleaning machine. The fruit and vegetable cleaning machine comprises a machine body, a washing barrel for containing water, an upper cover and a washing basket for containing fruits and vegetables, wherein a washing rotating shaft is arranged in the washing barrel; the washing basket is arranged on the washing rotating shaft; the fruit and vegetable cleaning machine also comprises an ozone generator, an aerating apparatus and an aerating rotating shaft, and the aerating apparatus and the aerating rotating shaft are arranged on the washing barrel; the aerating apparatus is arranged on the aerating rotating shaft; an air inlet hole communicated with the ozone generator is formed on the washing barrel; a driving device for driving the washing rotating shaft and the aerating rotating shaft to rotate is arranged in the machine body; the aerating apparatus comprises a suction port and an aerating piece; ozone generated by the ozone generator enters the washing barrel through the air inlet hole to form ozone bubbles; and the ozone bubbles are aerated by the aerating apparatus to be broken up, micro-fined down and rapidly dissolved in water. Therefore, the drawback of the traditional aeration stone is avoided, the concentration of the ozone dissolved in and entering water is ensured to the maximum extent, the purification effect of fruits and vegetables is ensured, the utilization rate of the ozone is increased while the dissolving efficiency of the ozone is increased through repeated aeration, and energy sources are saved.

Description

technical field [0001] The invention relates to the technical field of household food processing, in particular to a fruit and vegetable cleaning machine. Background technique [0002] Existing household ozone fruit and vegetable cleaning machines generally provide ozone into the washing bucket through an air blasting stone. In order to ensure sufficient dissolution of ozone, a water circulation device is usually provided to increase the ozone dissolving capacity of water through circulation. [0003] However, it takes a certain amount of time for ozone to dissolve in water. The water circulation of existing fruit and vegetable washing machines is not strong enough, resulting in a short residence time of ozone in water and low mixing efficiency, which leads to the sterilization and detoxification of ozone fruit and vegetable washing machines, and the removal of pesticides and heavy metal residues. If it is necessary to obtain the saturated ozone water required for cleaning f...

Problems solved by technology

[0003]However, it takes a certain amount of time for ozone to dissolve in water, and the water circulation of existing fruit and vegetable washing machines is not strong enough, resulting in a short residence time of ozone in water and low mixing efficiency , leading to the sterilization and detoxification of the ozone fruit and vegetable cleaning machine, and the poor performance of removing pesticides and heavy metal residues. If it is necessary to obtain saturated ozone water required for cleaning fruits and vegetables, the time will be lengthened, resulting in long working hours and low efficiency of the ozone fruit and vegetable cleaning machine. , resulting in a waste of energy; in addition, the ozone generator continues to supply ozone to the water in the washing bucket through the blasting stone. Due to the poor mixing efficiency, some ozone that cannot be dissolved immediately will inevitably overflow the water surface, and the overflowed ozone will be discharged into the air through the vent hole will cause environmental pollution and even endanger human health

[0004]In addition, microporous air aeration stone technology also appears in the existing products. The air aeration stone is placed in water, and ozone gas is passed through the microporous air aeration stone to form a relatively There are many small ozone bubbles, and the small ozone bubbles increase the contact area with water to improve the efficiency of ozone dissolution. However, after long-term use of the microporous air aeration stone, it is easy to condense scale and block the micropores, so that bubbles cannot be generated, and even It will cause pipeline pressure and cause danger, and the air aeration stone is easy to be damaged during installation. If the installation is not good, it will cause uneven distribution of ozone gas when it enters the microporous air aeration stone, which will affect the size of the bubbles and affect the gas-liquid mixing effect
