Technical Field

[0001] The utility model relates to the field of far-infrared heating, in particular to a far-infrared energy-saving heater with an integrated shield. Background Art

[0002] Far infrared heating technology uses far infrared rays emitted by a hot object source to irradiate the heated material, so that the material absorbs the far infrared rays and the internal molecules and atoms "resonate" to generate heat energy to achieve the purpose of heating. It is a radiation heat transfer process. This technology can improve heating efficiency and save energy. There are several types of far infrared heaters, such as plate, tube, lamp and lamp holder. The energy used is mainly electric energy.

[0003] The far-infrared energy-saving heater rings used today adopt radiation heating, and the quality of the internal heating tube determines the service life of the heater. Due to the fragile nature of the quartz tube itself, the internal heating tube often breaks when the heater is in use, causing the resistance wire to burn out or leak electricity, thereby reducing the service life of the heater and even causing safety accidents such as fire.

[0004] Therefore, it is necessary to propose a shield-integrated far-infrared energy-saving heater to solve the above problems. Utility Model Content
