Description

Technical Field

[0001] The invention relates to a fruit and vegetable cleaning machine. Background Art

[0002] Existing fruit and vegetable washing machines usually achieve cleaning in two ways: one is to drive the washing basket to rotate horizontally and spray water from top to bottom into the washing basket to rinse the fruits and vegetables in the washing basket; the other is to use a water pump to pump water from the bottom of the washing barrel to a certain height and then spray it out to achieve spray washing of fruits and vegetables.

[0003] The first cleaning structure is a new type of fruit and vegetable cleaning machine disclosed in Chinese patent application number 201420767984.1, which includes a spray device, a cleaning basket arranged in a cleaning barrel, and a synchronous motor arranged at the bottom of the cleaning barrel. The spray device includes a water pump and a nozzle. The water inlet of the water pump is arranged on the side wall or the bottom of the cleaning barrel, and the water outlet of the water pump is connected to one end of a water guide pipe arranged on the side of the cleaning barrel. The other end of the water guide pipe opens on the upper side of the cleaning basket, and a nozzle with an adjustable installation angle is arranged at its end. When the synchronous motor drives the cleaning basket to rotate, the spray device sprays and cleans the fruits and vegetables in the cleaning basket.
