It is an external appearance structural example of the balance pot cleaning apparatus of this invention. It is sectional drawing of the gas-liquid mixing nozzle of the balance pot cleaning apparatus of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an external configuration example of a balance pot cleaning device of the present invention. FIG. 2 is a cross-sectional view of the gas-liquid mixing nozzle.

The balance kettle washing apparatus 100 includes a nozzle 101, an air compressor 102, and a water supply pump 103. The nozzle 101 and the air compressor 102 are connected by a tube 121, and the nozzle 101 and the water supply pump 103 are connected to a hose 131. Are connected.

The balance kettle cleaning device 100 physically removes the scale of the inner pipe by the bubbles and the water flow by sending the bubble mixed water from the nozzle 101 to the inner pipe of the balance kettle B.

The nozzle 101 has a concentric double-cylindrical structure, and is provided with a water passage mounting portion 111 at the front end and a tube mounting portion 112 at the rear end. The water passage attachment portion 111 is for attaching the nozzle 101 to the water passage H of the balance hook B, and can be closely attached to the water passage H of various diameters by an attachment. The tube attachment portion 112 attaches the tube 121 to the nozzle 101 and guides air from the air compressor 102 to the inner tube 113.

The inner pipe 113 extends to the vicinity of the water passage attachment portion 111 and ejects air from the air compressor 102. Note that the tip may be appropriately reduced in diameter to further increase the atmospheric pressure and increase the generation efficiency of the bubble mixed water.

Further, on the outer periphery of the nozzle 101, a hose attachment portion 114 is erected vertically to the nozzle 101, and the hose 131 is attached to the hose attachment portion 114. The hose attachment portion 114 is at a position of 1/5 to 1/3 of the front end side of the entire length of the inner tube 113.

Thus, by supplying water from the direction near the front end and perpendicular to the extending direction of the nozzle 101, the water is killed and the water is mixed with air before being rectified. Thus, bubble mixed water is generated.

The water supply pump 103 is a submerged pump and uses the remaining hot water in the bathtub. In tap water, since the water pressure and the amount of water differ depending on the bathroom, the balance kettle cleaning device 100 can supply the rated air in order to generate and supply a suitable bubble mixed water, and is suitable for use in the bathroom. A submersible pump is used.

The air compressor 102 supplies air to the nozzle 101 by periodically increasing and decreasing the air supply amount. Since the water supply pump 103 supplies a constant amount of water, the air compressor 102 can increase or decrease the air supply amount periodically, thereby increasing the pressure of the bubble mixed water and the size of the bubbles. Thereby, it becomes the balance pot washing | cleaning apparatus 100 which can be adapted even if the diameter, shape, and full length of the inner pipe of the balance hook B differ for every object bathroom.

In addition, since the bubble mixed water is slowed down, the dirt adhering to the inner tube of the balance hook B is subjected to various forces and the cleaning efficiency is improved.

At the time of use, in the state where water has been stretched in the bathtub, the water inlet mounting portion 111 is attached to the water outlet H (the water outlet H has two locations at the top and bottom, for example, the lower water outlet H). Next, the water pump 103 is driven, and further the air compressor 102 is driven. After a predetermined time has elapsed, the air supply of the air compressor is periodically changed. After confirming that the scale does not come out from the other water inlet H, the washing is finished.

As described above, by using the balance kettle cleaning device of the present invention, the generation efficiency of bubble mixed water is increased, and a cleaning service can be provided at a low cost with a simple structure.

The balance kettle cleaning device of the present invention can also be used for cleaning solar water heaters.
