Abstract

The invention discloses an energy-saving heater of a positive temperature coefficient (PTC) water heater. The heater comprises a flange and a heating body fixed on the flange, wherein the heating body comprises a metal pipe arranged at the outer layer, an insulation layer arranged in the metal pipe, a plurality of PTC ceramic heating sheets arranged in the insulation layer, an upper electrode sheet and a lower electrode sheet which are arranged between the insulation layer and the PTC ceramic heating sheets, and a terminal sheet connected with the electrode sheets. The heater has the advantages of automatically controlling the temperature, saving energy, performing heating without water without explosion and conveniently adjusting power; moreover, the heater also has the advantages of high safety, simple structure and convenience in use.

Description

technical field [0001] The invention relates to a heating device, in particular to a PTC water heater heater. Background technique [0002] As everyone knows, water heater is a kind of device that is used for heating water, and its application is very extensive. There are also many types of water heaters on the market. The core component of the water heater is the heater installed inside. The existing heater structure mainly includes: a flange and a heating element fixed on the flange. The structure of the heating element includes: Layered metal tube, magnesium oxide powder insulation layer set in the metal tube, resistance wire set in the magnesium oxide powder insulation layer and terminals connected to the resistance wire. The existing heater has poor safety performance, is not energy-saving, cannot be dry-burned, and is prone to tube explosion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-savin...
