Electric water heater having air preheating function

Abstract

The invention discloses an electric water heater having an air preheating function. The electric water heater comprises a housing, wherein a liner is arranged in the housing, and comprises a water storing cavity body; a bended hollow electric heating pipe is arranged in the water storing cavity body; a wind channel is formed in the inner cavity of the electric heating pipe; a heating wire is arranged in the gap between the inner cavity wall and an outer wall of the electric heating pipe; the left end of the wind channel in the electric heating pipe communicates with the right end of an insulation wind outlet pipe, and the right end of the wind channel in the electric heating pipe communicates with the left end of an insulation wind inlet pipe; a wind inlet is formed in the right end of the insulation wind inlet pipe, and a wind outlet is formed in the left end of the insulation wind inlet pipe; the wind outlet communicates with the space environment of a user; and one or more circulation fans are arranged in the insulation wind outlet pipe. Through the adoption of the electric water heater disclosed by the invention, when people are bathed, the bathing space of people is in automatic hot wind circulating heating, so that the bathing environment of the people is effectively improved, convenience is brought to the daily life of the people, and the body health of the people is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to an electric water heater with air preheating function. Background technique [0002] At present, with the growth of the economy, people have higher and higher requirements for the quality of life, and one of the requirements is reflected in the demand for the bathing environment in winter. For areas or residences without heating in winter, the indoor temperature is low and the bathing conditions are poor, which directly affects people's bathing comfort, and may even cause a cold and fever due to catching a cold. [0003] However, the existing water heaters can only be used to provide hot water for bathing, but cannot create a good bathing environment, which affects the widespread use of water heaters in non-heating areas (such as most of the southern rural areas of China). [0004] Therefore, a technology is urgently developed at present, which can effectively imp...
