High-temperature and high-pressure washer equipped with a payback period of the waste heat of the exhaust gases

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-temperature and high-pressure washer having a waste heat recovery apparatus for exhaust gas, and its object is to reduce the material cost associated with the washing machine manufacturing, reduce the weight of the washing machine, And the fuel can be supplied to the air supply fan side of the fuel combustion unit unit by heating the outside air using the air supply unit. A case part for hot water boiler which is formed so as to be capable of discharging the combustion gas and is capable of heating the outside air with the heat of the exhaust gas to be supplied to the fuel combustion unit part side, The boiler casing portion is exposed and exposed at one end and the other end, A hot water boiler part which is provided at one end with a low pressure pipe according to the possibility of being directly connected to the faucet and is provided so as to discharge hot water to the other end by exchanging cold water introduced into the one end with hot water corresponding to driving of the fuel combustion unit, A high pressure pump which is mounted on the case so as to be able to discharge hot water heat exchanged at a high temperature to a high temperature and is drivable under the control of a control unit; And an injection nozzle unit unit provided so as to be capable of spraying wash water.
