Washing device and operation method

Abstract

The present invention discloses a washing device and an operation method. The device includes a box body, a water tank is arranged within the box body, and a cavity is formed between the boxy body and the water tank. Pluralities of air-entrapping spray-heads are distributed at the bottom of the water tank. Water inlets of the air-entrapping spray-heads are connected to an internal circulation water pump, a water inlet of the internal circulation water pump is connected to the water tank, and the internal circulation water pump is located within the cavity below the water tank. A multi-porous separation plate is arranged above the air-entrapping spray-heads in the water tank, and a sewage draining outlet is arranged at the bottom of the water tank. The device can effectively reduce labor intensity, improve the washing efficiency, save and utilize water resources, maintain the nutritional value and hygienic indexes of fruits and vegetables, and meet the demands of people for fresh and high-nutritional fruits and vegetables.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment for fruits and vegetables, dishes, small pieces of clothing, etc., and specifically relates to a household cleaning device and its operation that are water-saving, high in cleaning degree, and have an intuitively visible cleaning effect, and are used for cleaning fruits and vegetables without damaging the skin of fruits and vegetables. method. Background technique [0002] Fresh vegetables and fruits are important sources of nutrients such as vitamins, trace elements, and proteins for people. However, pesticides and other harmful chemicals remaining on fruits and vegetables threaten human health and have aroused great concern. At present, in terms of the removal of residual pesticides and harmful chemicals, soaking in clear water, salt water, and detergent known to ordinary people cannot truly degrade and remove them. At present, the fruit and vegetable cleaning equipment sold by merch...

AI Technical Summary

Problems solved by technology

However, the design of the vertically upward tumbling nozzle located at the bottom of the fruit and vegetable cleaning tank and the impact nozzle located on the upper part of the fruit and vegetable cleaning tank makes the water in the fruit and vegetable cleaning tank rotate. good

In addition, although the scheme has set up a water circulation treatment area so that the water in the tank can be recycled, the lower water level sensor used to control the amount of water injection is set at a higher position, so that the minimum water injection amount is still relatively large. When the number of fruits and vegetables to be cleaned is small Poor water saving effect

[0005] For strawberries, apples, clusters of berries and grapes, fruits such as highly ripe peaches, vegetables such as potatoes and yams that are easily oxidized, and leafy vegetables such as spinach, these fruits and vegetables are sprayed by the impact nozzle with high-speed impact water and drum rotary Collisions under the action of currents have a high probability of skin damage, which can easily cause nutrient loss and secondary pollution of fruits and vegetables, and food safety cannot be guaranteed
