Description

Bubble Washstand {Washstand device}

The present invention relates to a bubble sink, and more specifically, by generating and discharging fine bubble water, the fine bubble water can be used to bathe pets, wash fruits or ingredients, or wash the face and body parts. This is about a bubble sink that provides bubble water.

Micro bubbles are several micrometers in size, which is much smaller than regular air bubbles. In addition, fine bubbles rise at a slower rate in water than regular air bubbles, remain underwater for a longer time, and generate high negative pressure and momentary high heat when destroyed.

As fine bubbles grow and break down, thermal decomposition occurs due to instantaneous high heat in the gas area where air stays, and radicals become greatly activated in the interface area where air and water coexist, resulting in oxidation. Due to these physical and chemical properties, it is widely used in sterilization and cleaning fields.

Fine bubbles used in household goods include washing water for vegetables and fruits, beauty water, etc. In Patent Document 1 and Patent Document 2, fine bubbles are generated by impact through a combination of mechanical components such as protruding pins and discharge holes on the flow path of the shower connected to the faucet.

This conventional technology only allows the generation of fine bubbles when the water pressure is sufficiently high, and has the disadvantage of not being able to obtain sufficient fine bubbles due to the low water pressure when connected to a general commercial water supply. Therefore, there are limits to the use of the product, as it is not widely used in ordinary homes and is mainly distributed to commercial facilities such as hotels.

Furthermore, there is a disadvantage in that high-quality fine bubble water cannot be obtained by discharging a large amount of general bubbles generated along with fine bubbles.
