Heating device

Abstract

The invention discloses a heating device comprising a power supply input part, an energy storage unit, a heating unit and a processing unit, wherein the power supply input part receives electric energy from a voltage source; the energy storage unit comprises at least one magnetic capacitance for storing and releasing electric energy; the heating unit is used for providing heat energy; the processing unit is coupled between the energy storage unit and the heating unit for controlling the heating unit to selectively receive electric energy input by the voltage source or the electric energy output by the energy storage unit to operate.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device with energy-saving effect. Background technique [0002] At present, heating devices with heating and heat preservation effects have been developed on the market, such as electric thermos bottles, drinking machines, heating electric kettles, electric hot pots, etc., and their operation methods are mainly to receive mains electricity to heat the water in the electric thermos bottles. After reaching the boiling point, disconnect the mains power supply path and enter the heat preservation state. At this time, the electric thermos will detect the temperature of the water in the bottle at any time. Once the water temperature drops to a certain level, it will be turned on and continue to receive the mains power for heating. This keeps circulating to achieve the heat preservation mechanism. [0003] Since the mains electricity belongs to alternating current, it is necessary to conve...

Problems solved by technology

However, a heating device with power storage function has been developed, that is, a storage battery is arranged in the heating device, and the fully charged storage battery provides electric energy for the heating device to operate as a backup. However, the current storage battery, although advertised It can be used repeatedly, but it still has its life limit

In the case of repeated charging and discharging or long-term non-use, the capacity of the battery will decrease and it will be easily damaged. The reason is that the battery uses chemical energy to convert it into electrical energy. Chemical substances must always maintain their activity so as not to fail and deteriorate. When the activity of the original compound is used up or nearly used up, no new chemical reaction can be carried out, which leads to the aging of the storage battery and the end of its service life

Therefore, the characteristics of the storage battery such as small capacity, short service life, and few charge and discharge times will still cause the inconvenience of frequent charging or replacement of the storage battery.
