A portable hot liquid (e.g. water) dispensing apparatus comprises a battery, a heating element, a liquid reservoir, a pump, an outlet, and a pipe extending from the reservoir to the outlet and passing adjacent the heating element. In operation, the pump drives liquid from the reservoir into and through the pipe while the power source causes the heating element to heat the liquid passing through the portion of the pipe adjacent to the heating element to be expelled from the outlet (optionally adjacent to a brush) at a temperature greater than the ambient temperature. The temperature of the liquid may be controlled via the pump, the diameter of the pipe or the voltage of the battery. The pipe may be coiled around the heating element, and optionally also around a second heating element to form a coiled heating unit. The pipe may further be coiled around the coiled heating unit. The apparatus may also be able to dispense steam. The apparatus may be used for cleaning (e.g. removing chewing gum), or as a portable hot water source (e.g. in a caravan, tent or recreational vehicle (RV)). |
