The invention discloses a tubular electric heating element, which is characterized in that a small hole communicated the inside and the outside is formed on a tube wall of a tubular electric heating body, one end of the tubular electric heating body is closed off with a clocking cover, the other end of the tubular electric heating body is connected with a water inlet pipe joint, an outer cylinder is sleeved on the periphery of the tubular electric heating body, a cylindrical cavity is formed between the outer cylinder and the electric heating body, one end of the outer cylinder is in a sealed state, and the other end of the outer cylinder is connected with a water outlet pipe joint.
Description
technical field [0001] The invention relates to an electric heating element, in particular to a tubular electric heating element, and belongs to the technical field of water heaters. Background technique [0002] At present, the electric heating body used in the existing instant electric water heater can generally be divided into two types, one is a rod-shaped electric heating body, which is heated when water flows through its surface during the working process; the other is a tubular electric heating body. The electric heating body, in the working process, the water flows through its inner hole to be heated. These two structures all have the defects of insufficient heat utilization and slow heating speed. Contents of the invention [0003] The object of the present invention is to provide a tubular electric heating element to overcome the above-mentioned defects in the existing electric heating elements. [0004] The technical solution adopted by the present invention t...
