Detachable instant type heater

Abstract

The invention discloses a detachable instant type heater. A double-ring coiled pipe comprises a coiled pipe outer ring and a coiled pipe inner ring; the coiled pipe inner ring is arranged in the middle of the coiled pipe outer ring; the upper end of the coiled pipe inner ring is communicated with the upper end of the coiled pipe outer ring in a sealing mode; the lower end of the coiled pipe outer ring is a coiled pipe water inlet; the lower end of the coiled pipe inner ring is a coiled pipe water outlet; heat conduction materials casted outside the double-ring coiled pipe; space between the coiled pipe outer ring and the coiled pipe inner ring is a heater groove; the upper end of the heater groove is closed and the lower end is open; an electric heater body is arranged inside the heater groove; tolerance clearance is formed between the electric heater body and the heater groove; colloidal state thermal conduction materials paint inside the tolerance clearance; a central position of the coiled pipe inner ring is provided with a temperature sensor blind pipe; the electric heater body comprises a heater outer casing; heating wires are arranged inside the heater outer casing; an insulation layer is arranged between the heating wires and the heater outer casing; the heating wires are in U shapes; positive and negative ends of the heating wires respectively penetrate the insulation layer to be fixedly connected with heating wire binding posts; the heating wire binding posts comprise a positive terminal binding post and a negative terminal binding post.

Description

technical field [0001] The invention relates to an electric heater, in particular to a detachable instantaneous heater. Background technique [0002] Instantaneous electric heaters are widely used in various water heater products and household water heaters. They are in various forms and are the core components of water heaters. At present, the most widely used metal tube electric heaters are widely used in various water heaters and need Among the equipment for electric heating water intake, but the metal tube electric heater has been soaked in water for a long time, the water and electricity cannot be completely isolated, and it is easy to corrode and leak electricity. If it is completely covered by scale, the heat cannot be dissipated. If it is light, the electric heating itself will be damaged, and if it is serious, a fire accident will occur, and the safety performance is low. Contents of the invention [0003] The object of the present invention is to provide a detac...
