A spray arm and a cleaning machine using the spray arm

Abstract

The invention relates to a spray arm, comprising a body with a hollow interior, a first baffle plate capable of dividing the bottom space of the body into relatively independent first flow channels and second flow channels is arranged in the body, and a side wall of the body is provided with a first baffle plate. The water inlet communicated with the first flow channel and the water outlet communicated with the second flow channel; the first flow channel is provided with a second baffle that can be divided into a water inlet area and a water storage area, and the second baffle is provided with only a The first one-way valve allows water to enter the water storage area from the water inlet area, and the first baffle plate is provided with a tapered hole with a gradually increasing inner diameter along the water flow direction for the water supply from the water storage area to enter the second flow channel. The process of producing the micro-nano bubble water in the invention does not need to provide power and perform electric control operation, which not only simplifies the structure of the equipment, but also reduces the cost and improves the reliability of use; The negative charge has the chemical effect of improving the interface activity, which is beneficial to improve the cleaning effect.

Description

technical field [0001] The invention relates to a spray arm structure of household washing electrical appliances, and also relates to a washing machine which is applied with the water inlet structure and can be used for washing tableware, vegetables or fruits. Background technique [0002] With the gradual maturity of micro-nano bubble cleaning technology, the application in the field of home appliances has become more extensive. [0003] In the field of industrial applications, nano-sized bubbles refer to fine bubbles below 1000 nm in liquid. Further, the bubbles between 1 and 100 μm are called micro-bubbles, and the bubbles above 100 μm are called ordinary bubbles. In water, compared with ordinary bubbles, micro-nano bubbles have the characteristics of long existence time, high surface energy, negative surface charge, high gas-liquid mass transfer rate, and the ability to spontaneously generate free radicals. Sterilization, disinfection, washing, decontamination, water pu...

Problems solved by technology

Most of the above-mentioned existing micro-nano bubble generating devices use an air pump to provide a power source to mix in air, and after the air and water are fully mixed and dissolved, the pressure is released to obtain micro-nano bubbles with a high concentration. The realization structure of this method is relatively complicated and costly. High, and need to rely on the circuit for control, poor reliability
