Abstract
The utility model discloses a novel variable volume electric water heater. A hot water outlet pipe in an inner container of the variable volume electric water heater consists of a first water outlet pipe and a second water outlet pipe, the heights of the water inlet ends of the first and second water outlet pipes are different, and the first and second water outlet pipes are independently arranged at an interval in the inner container. The first and second fluid inlet ends of a switching valve are communicated with the water outlet ends of the first and second water outlet pipes respectively. When the hot water outlet pipe is switched to the first water outlet pipe which is longer by the switching valve during the use of the variable volume electric water heater, the whole inner container is filled with water; and when the hot water outlet pipe is switched to the second water outlet pipe which is shorter, only a half of the inner container is filled with the water. The amount of water to be heated can be selected by a user according to different seasons and different water consumptions, so that the high-efficiency heating of an electric heating pipe is realized, the irrational waste of hydroelectric resources is avoided, and cost required by the adoption of a layered heating method is also avoided.
