<p>PROBLEM TO BE SOLVED: To provide a simple cleaning device which does not use an electric pump and a cleaning method using the cleaning device so as to solve a problem that a high pressure cleaning device is generally used for cleaning a drain pipe, but the high pressure cleaning device requires an electric pump and a large amount of water and it cannot be used in places without power and a water source.SOLUTION: A foam cleaning device 1 sucks a liquid cleaning agent in a chemical tank 11 by making gas in a gas cylinder 10 flow in a vacuum generating pump 12 and putting in a vacuum state. The liquid cleaning agent containing the gas passes through a mesh filter 13, generates a mousse-like cleaning agent 18 formed of micro-sized foam, is delivered to a nozzle 15 by utilizing a pressure of the gas cylinder 10, and is discharged and fills an inside of the drain pipe. After a predetermined time passes, the cleaning agent and dirt in the drain pipe is washed away by tap water. Thereby, the simple foam cleaning device and foam cleaning method which do not use the electric pump can be provided.</p> |
