Temperature control apparatus applied to heater

Abstract

The invention relates to a temperature control apparatus applied to a heater. The temperature control apparatus comprises a temperature sensor, a single-chip microcomputer, a liquid crystal display module, a power supply module, a Bluetooth communication module, a primary protector and a secondary protector. The primary protector comprises a temperature controller and a normally closed contact. The secondary protector comprises a fuse. The primary protector and the secondary protector are serially connected with the power supply module. By making full use of the single-chip microcomputer for intelligent control and the Bluetooth for communication with mobile terminals, the temperature control apparatus can have the intelligent performance and the maneuverability obviously improved. The unique dual protection design including both the temperature controller and the fuse further improves the safety of the heater. The adopted temperature sensor with high sensitivity further makes the temperature acquisition accuracy improved. The apparatus which is convenient and intelligentized has high stability.

Description

technical field [0001] The invention relates to the field of electrothermal machinery, in particular to a temperature control device applied to a heater. Background technique [0002] Electric heater is an internationally popular high-quality and long-life electric heating equipment. It is used for heating, heat preservation and heating of flowing liquid and gaseous medium. When the heating medium passes through the heating chamber of the electric heater under pressure, the principle of fluid thermodynamics is used to uniformly take away the huge heat generated by the electric heating element during work, so that the temperature of the heated medium meets the user's process requirements. [0003] Electric heating is the process of converting electrical energy into heat energy. Since it was discovered that the power supply can produce thermal effects through wires, many inventors in the world have been engaged in the research and manufacture of various electric heating appl...

Problems solved by technology

As one of the important equipment in daily life, stainless steel electric heating tubes are traditionally used. Its structure is to put electric heating wires in the metal tubes, and the gaps are tightly filled with thermally conductive and insulating magnesium oxide powder. Its advantages The stainless steel electric heating tube is a purely resistive load, and the power is easy to determine. The disadvantage is that it can only be controlled on and off, and the power cannot be automatically adjusted according to the temperature.

At the same time, when dry burning occurs due to accidents, it is easy to cause the heating temperature of the stainless steel electric heating tube to be uncontrollable, causing great safety hazards and easily causing explosions, fires and other injuries.
