    • A portable power washer with an on-demand gas-heated water supply, is provided with a water heater for receiving water from an external water supply and rapidly heating the water by passing it though a heat exchanger proximate one or more gas burners. After the water flows through the heater it flows into a pump adapted for use with hot water and is pressurized by the pump for delivery to a high pressure hose. A nozzle or valve at the end of the hose opposite the pump allows a user to cause a stream of hot, pressurized water to eject from the nozzle and against a surface to be cleaned. The pump may be powered by an electric motor or gasoline engine and the device is typically assembled upon a wheeled cart for ready mobility.
    • 具有按需燃气加热供水的便携式功率洗衣机设置有用于从外部水源接收水的热水器,并且通过使其通过靠近一个或多个气体燃烧器的热交换器来快速加热水。 在水流过加热器之后,它流入适于与热水一起使用的泵,并被泵加压以输送到高压软管。 在与软管相对的泵的端部处的喷嘴或阀允许用户引起热的加压水流从喷嘴喷射并抵靠待清洁的表面。 泵可以由电动马达或汽油发动机供电,并且该装置通常组装在轮式推车上用于准备移动。
