Circulating air energy water heater convenient to clean

The circulating air energy water heater convenient to clean comprises a drainage mechanism, a supporting rod is fixedly installed on one side of the top of the drainage mechanism, a top plate is fixedly installed on the top of the supporting rod, a supporting column is rotatably installed on the top of the drainage mechanism, and a base is fixedly installed on the top of the supporting column. An air energy water heater body is placed on the top of the base, and a limiting mechanism is arranged in the top plate. Through the arrangement of the drainage mechanism, sewage discharged during repair and scale blocks falling off during cleaning can be well collected, and the situation that the sewage flows randomly during repair, and the surrounding sanitation is affected is prevented; by means of the limiting mechanism, the clamping mechanism and the rotatable base, the angle of the air energy water heater body can be conveniently adjusted, maintenance is more convenient, meanwhile, the adjusted angle can be fixed,
