Description

Technical Field

[0001] This utility model belongs to the field of oven technology, and in particular relates to an oven using a flat infrared heater. Background Technology

[0002] Heated ovens are widely used in the food, chemical, and pharmaceutical industries. Common types include hot air heated ovens, which typically use steam, electric heating wires, or gas to heat the air and then use a hot air circulation system to transfer the heat to the object to be heated. However, these ovens have high energy consumption, significant energy loss, uneven internal temperatures, and often result in the surface drying of the heated object. They also pose certain safety hazards. Some infrared quartz lamp ovens use quartz lamps as the infrared radiation source, but these have problems such as short lamp life, fragility, and limited radiation area. Utility Model Content

[0013] Furthermore, the flat plate heater is an infrared radiation heater.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention uses a flat-plate infrared radiation heater to replace the easily damaged quartz lamp tube, extending the equipment's lifespan, increasing the radiation area, and achieving uniform heating inside the oven. This eliminates the shortcomings of infrared lamp tubes, such as small radiation area and uneven temperature. Infrared radiation has a certain penetrating effect, allowing it to directly heat the interior of objects and helping to reduce surface dryness. The heating method of thermal radiation solves the problems of low energy efficiency and insufficient heat utilization in traditional hot air ovens. Furthermore, the infrared radiation structure is simple and easy to industrialize. Attached Figure Description
