PORTABLE WATER HEATER

摘要

A hand-held dispenser of hot water intended for weed control purposes has a handle (300) containing a hose connection (110), a flow regulator (111) and a power switch (103). The handle (300) is connected to a tube (302) which contains a main electric water heating element (107) surrounded by a tube (304) through which water can flow from the bottom of the wand towards the handle (300) before being piped through an exit tube to the nozzle (114). A temperature sensor (108) is positioned adjacent the handle (300) so that amount of power supplied to the heating element (107) can be regulated. One version uses a microprocessor to control the heating, the other uses two heating elements and a thermostat.
