Technical Field

[0001] The utility model relates to the technical field of hot air units, and more specifically, to a solid heat storage type hot air unit. Background Art

[0002] Industrial hot air unit, also known as air heating unit, is a hot air device used in industrial production processes such as heating, drying, and baking. It generates hot air by burning fuel or electric heating, and then transmits the hot air to the industrial equipment or production environment that needs to be heated. Industrial hot air units usually have large power and heating capacity, which can meet the large-scale heating needs in industrial production.

[0003] Most of the hot air units currently in use are electric hot air units, which do not produce waste gas and waste water during use and do not pollute the environment.

[0009] The heat storage box is connected to an air duct on one side away from the air duct. The effect is that, through the coordinated use of the hot air furnace, the solid heat accumulator and the regulating mechanism, when the device is used for heating, the device is used for heating during off-peak hours, and the solid heat accumulator is heated at the same time to store the heat in the solid heat accumulator. During peak hours, the heat stored in the solid heat accumulator is used to heat the air, thereby reducing the use of electricity, saving electricity bills and reducing costs.
