The guide part 61 is formed to have a predetermined angle with the guiding wall 60 along the flow direction of water.

The operation of the rotary stir induction type water tank using the water pressure difference and the internal water pressure according to the present invention is as follows.

1. Intake.

Water is supplied from the bottom to the top of the inner tank 20 through the inlet pipe 30 and is discharged toward the bottom of the inner tank 20 through the outlet pipe 31 to be obtained.

2. Internal tank storage.

Some of the water obtained through the water inlet pipe 30 is stored in the inner tank 20 .

3. Induction of rotation by inlet pressure.

Some of the water obtained through the water inlet pipe 30 is sprayed into the reservoir between the inner tank 20 and the tank body 10 without passing through the inner tank 20 through the rotary stir guide tube 50, and this At this time, through the injection direction of the rotary stirring nozzle 54, water forms a vortex between the inner tank 20 and the tank body 10 to rotate the water.

At this time, the guiding wall 60 does not interfere with the water sprayed from the rotary stir nozzle 54 at the rear of the rotary stir nozzle 54, so that the water sprayed by the rotary stir nozzle 54 shows its directionality. It can be maintained in the form of a vortex, and thus, smooth directivity is maintained between the inner tank 20 and the tank body 10 .

4. Tank body storage and stirring disinfection.

The water stored in the inner tank 20 is transferred to the tank body 10 through the delivery pipe 40, and at this time, it is sprayed through the rotational stir induction tube 50 and merges with the water forming a vortex to form the inner tank ( A vortex is formed between 20) and the tank body 10, and in this process, water and chemicals are actively stirred, so that harmful substances are removed and disinfected from the water.

Since both the delivery pipe 40 and the rotary stirring nozzle 54 form a vortex, the water sprayed from them does not collide with each other and maintains a smooth vortex, so that the stirring ability is increased, thereby maximizing the water purification efficiency.
