According to the cleaning apparatus 11 having the above-described configuration, first, the connecting members 44, 47, 49, and 5 are used.
The two on-off valves 44a, 47a, 49a, 52a are all opened and the air compressor 12 is driven. Then, the switching valve 58b of the connecting member 58 is opened and the switching valve 5 is opened.
When the lever 56 of the cleaning gun 16 is pulled toward the grip portion 55 in a state where the nozzle 8a is closed, the cleaning gun 16 mixes the compressed air and the detergent and jets out from the nozzle 59.

That is, in this state, the compressed air from the air compressor 12 is introduced into the mixing chamber of the cleaning gun 16, and the detergent from the detergent tank 14 is introduced into the mixing chamber of the cleaning gun 16, and these compressed air are introduced. And the detergent are mixed in the mixing chamber, and are spouted from the nozzle 59 in the form of foam. At the time of this jetting, the nozzle 59 causes the flat portion 66 to bend in the flattening direction and causes a high-speed reciprocating movement (approximately 40
Times / second). Due to the high-speed reciprocating movement of the nozzle 59, a wave is generated in the bubble passing through the nozzle 59, and a strong shock wave is ejected from the nozzle 59. Therefore, the bubbles ejected from the nozzle 59 become fine bubbles in the air, reach the object to be cleaned, and are sent to the back of the object to be cleaned with a strong force.

Accordingly, the detergent can be sufficiently and finely foamed, and can be sent to the back of the object to be washed with a strong force. Therefore, the dirt of the object to be washed can be surely removed with a minimum amount of detergent.

The compressed air and water are mixed in the mixing chamber, and are ejected from the nozzle 59 in the form of a mist.
At the time of this ejection, the nozzle 59 generates a high-speed reciprocating motion (about 40 times / second) on the ejection tip side while bending the flat portion 66 in the flat direction by the force of water and compressed air flowing through the nozzle 59. Will be. This nozzle 59
With the high-speed reciprocating motion of, the water passing through the nozzle 59 generates a wave motion and becomes a strong shock wave, which is ejected from the nozzle 59. Therefore, the water spouted from the nozzles 59 becomes fine mist in the air, reaches the object to be cleaned, and is sent to the back of the object to be cleaned with a strong force.

[0038] Therefore, the water can be sufficiently and finely atomized and can be sent to the back of the object to be washed with a strong force, so that the detergent of the object to be washed can be reliably washed away with a minimum amount of water. it can. Specifically, the detergent can be dropped with about 1/20 of the amount of water that was required until then.

Further, the switching valves 58a, 5 of the connecting member 58
When both levers 8b are closed and the lever 56 of the cleaning gun 16 is pulled toward the grip 55, the cleaning gun 16 is switched to a state in which only the compressed air is ejected from the nozzle 59. That is, in this state, the air compressor 1
Only the compressed air from 2 is introduced into the mixing chamber of the cleaning gun 16 and blows out from the nozzle 59. At the time of this ejection, the force of the compressed air flowing through the nozzle 59 causes the nozzle 59
However, a high-speed reciprocating motion (about 40 times / second) occurs on the ejection front end side while bending the flat portion 66 in the flat direction. The high-speed reciprocating motion of the nozzle 59 causes the nozzle 5
Waves are generated in the compressed air passing through the inside 9 and become intense shock waves, which are ejected from the nozzle 59. Therefore, the compressed air ejected from the nozzle 59 is sent to the back of the object to be cleaned with a strong force.

Therefore, the compressed air is ejected from the nozzle 59 with a larger ejection power and is sent to the back of the object to be cleaned, so that water droplets and the like of the object to be cleaned can be reliably blown off, and the object to be cleaned can be blown off. Can be dried immediately.

In addition, the switching valves 58a, 5 of the connecting member 58
When the lever 56 of the cleaning gun 16 is pulled toward the grip portion 55 with both of the nozzles 8b open, the cleaning gun 16 switches to a state in which the compressed air, water, and detergent are mixed and ejected from the nozzle 59. . That is, in this state,
The compressed air from the compressor 12 is introduced into the mixing chamber of the cleaning gun 16, the water from the water tank 13 is introduced into the mixing chamber of the cleaning gun 16, and the detergent tank 14
Is introduced into the mixing chamber of the cleaning gun 16 and the compressed air, water and the detergent are mixed in the mixing chamber and the nozzle 5
It gushes out of 9 as a foam. And at the time of this eruption,
The force of the bubbles flowing through the nozzle 59 causes the nozzle 59 to reciprocate on the ejection tip side while bending the flat portion 66 in the flat direction. By the reciprocating motion of the nozzle 59, the bubbles ejected from the nozzle 59 become finer bubbles in the air and reach the object to be cleaned.

As a result, the detergent whose concentration has been adjusted with water is mixed with the compressed air and ejected from the nozzle 59 of the washing gun 16. Therefore, the detergent can be mixed with water and spouted with its concentration adjusted.

Here, as described above, since the guide cylinder 73 is provided on the cleaning gun 16 so as to be substantially concentric with the nozzle 59 outside the nozzle 59, the flat portion 66 of the nozzle 59 is When the reciprocating motion is generated on the ejection tip side while being curved in the flat direction, the range of the reciprocating motion is determined by the guide cylinder 73. Therefore, the range of ejection by the nozzle 59 can be set.

In addition, since the air compressor 12, the water tank 13, and the detergent tank 14 are mounted and fixed on a movable carriage 15, the carriage 15 is moved.
The washing place can be easily changed. Further, since the water tank 13 and the detergent tank 14 are arranged in parallel above the air compressor 12 on the carriage 15, the whole can be reduced in size.

In the above embodiment, the grip 55
A connecting member 58 to which the pipe 50 and the pipe 53 are connected is attached to the rear end of the pipe, and the pipe 46 is connected to the lever 5 of the gun body 57.
