Description

Technical Field

[0001] The utility model relates to the technical field of baking ovens, in particular to a baking oven with multiple layers which is convenient for baking in different areas. Background Art

[0002] Baking oven is a kind of drying equipment. Baking oven is also called baking machine. Baking oven is widely used in precision baking, drying and shaping processing of optoelectronics, electronics, motors, communications, electroplating, plastics, mechanical equipment, etc. The temperature is controlled by connecting the digital display instrument with the temperature sensor. The hot air circulation air supply method is adopted. The hot air circulation system is divided into horizontal and vertical types, both of which are accurately calculated. The air source is driven by the air supply motor to drive the wind wheel through the electric heater, and the hot air is sent to the air duct and then enters the oven working room, and the used air is sucked into the air duct as the air source for re-circulation and heating, which can effectively improve the temperature uniformity.

[0003] Currently, it is common to fix the multi-layer baking plate to the bracket or frame inside the oven by bolts or screws. This connection method is simple and stable, and can ensure that the placement plate will not move or fall during use. However, when it is necessary to bake some larger objects, it is necessary to remove the bolts with tools so that it can adapt to the volume of the baked objects. However, it takes a long time to remove the bolts with tools, and there is a probability that the internal structure of the baking oven will be damaged during the removal process. At the same time, the bolts or screws may loosen due to long-term temperature changes, causing the placement plate to be unstable or fall, which poses certain safety hazards. Utility Model Content
