Description

Hot and cold water supply system for kitchen with nano bubble generator

The present invention relates to a water supply device applied to a kitchen and capable of selectively supplying hot and cold water, and more particularly, by nano-izing the gas contained in the process of transferring the supplied cold water and the mixed water of hot water and air. The present invention relates to a cold/hot water water supply device for kitchen to which a nanobubble generating means is applied to generate nanobubble water and selectively supply cold water and hot water containing nanobubbles when necessary.

In general, nanobubbles are ultra-fine bubbles that cannot be seen by the eye, and are microscopic air particles with a size of 1/2,000 of a normal bubble and less than 25 μm of pores on the skin. When extinct, 1) 40KHz of ultrasonic waves are generated, and 2) It generates a high sound pressure of 140db, and 3) instantaneous high heat of 4,000 to 6,000 degrees is generated.

In other words, general bubbles rise in the water and rupture at the surface, but the nanobubbles are reduced by pressure in the water, generating various energies and extinguishing.

These nanobubbles are mainly generated when water and air are violently rotated with ultra-fine bubbles.

Such nanobubbles are used in various fields due to their physical and chemical properties such as "gas dissolution effect, self-pressurization effect, charging effect", and in recent years, especially in the fields of fishing and agriculture, they are used in various aquaculture and hydroponic cultivation. In the medical field, it is used for precise diagnosis, and it is used in physical therapy, high-purity water treatment, and environmental devices in various fields.

In other words, the field of use is widely ranging from hot spring baths to cancer diagnosis, and it is known that it regenerates the skin and has excellent sterilization effects.

The nanobubbles as described above are generated in a variety of ways, such as a rotating liquid retention type, a state mixer type, an ejector type, a Venturi type, a pressure melting type, an ultrasonic type, an electrolysis type, and a microporous filter type.

In order to generate nanobubbles through such various types of nanobubble generating facilities or devices, a liquid (supplied water) mixed with gas is supplied and the gas is converted into microbubbles to generate nanobubbles.

The mixed water containing such nanobubbles increases the gas dissolution rate in the liquid while suppressing deaeration of the nanobubbles by using a separate gas dissolving device.

The nano-bubble dissolving device as described above, as known in Korean Patent Application No. 10-2007-0106679 (name: gas dissolving device/2007.10.23.), and a supply unit comprising a liquid supply unit and a gas supply unit and ; A dissolution tank coupled to the supply unit; And a discharge unit coupled to the other side of the dissolution tank; The end of the supply unit is configured to face the inner wall of the dissolution tank; The mixed water discharged from the end of the supply unit collides with the inner wall of the dissolution tank and is applied with a collision pressure to increase the generation of nanobubbles.
