Far infrared intelligent warmer and control circuit thereof

Abstract

The invention discloses a far infrared intelligent warmer and a control circuit thereof. The warmer comprises multiple radiating fins arranged in parallel, an electric cabinet mounted at the front ends of the radiating fins and heating bodies located in the radiating fins, wherein the upper part of the radiating fins is hinged with a pair of handles convenient to carry and for hanging clothes; a base is arranged at the lower part of the radiating fins; the electric cabinet is provided with a control circuit for controlling the heating of the radiating fins; and the control circuit comprises a control module, a display module, a key module, a room temperature sampling thermistor, a radiating fin temperature sampling thermistor, a full-power and half-power switch module and a heating body group. The warmer disclosed by the invention has the characteristics of simple structure, short preheating time, low manufacturing cost, long service life, light weight and the like, and is convenient to use, safe and reliable, low-carbon and healthy and energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a far-infrared intelligent heater and a control circuit thereof. Background technique [0002] Common heater on the existing market is an oil heater. It installs the electric heating tube inside the cavity of the heat sink, and injects heat-conducting oil around the electric heating tube in the cavity. When the power is turned on, the heat transfer oil around the electric heating tube is heated and rises to the upper part of the cavity, convectively circulates along the heat dissipation tube or heat sink, and radiates heat through the cavity wall surface, thereby heating the space environment. The heat transfer oil cooled by the air descends to the electric heating tube and is heated again to start a new cycle. [0003] The biggest feature of this heater is that it dissipates a large amount of heat. Even in the case of a sudden power failure, it will maintain a certain temperature for a long time. At the same time, it does no...

AI Technical Summary

Problems solved by technology

[0004] Although the oil heater has the above advantages, it also has some disadvantages. For example, when using an electric oil heater, it must be placed upright, because it heats the surrounding heat transfer oil through the heating tube at the lower end, so that the heat transfer oil flow in the duct to transfer heat

If it is placed upside down, flat or inclined, it will cause empty burning and burn out the heat pipe

Another example is that the preheating time of the oil heater is long, and the power is too large, and the family with small capacity of the electric meter or low voltage cannot use it.
