Description

Technical Field

[0001] The present invention relates to the technical field of baking equipment, and in particular to an intelligent hot air baking equipment provided with a hot air circulation structure. Background Art

[0002] Intelligent hot air baking equipment has broad application prospects in many industries such as electronics, chemicals, pharmaceuticals, automobile parts manufacturing, and food processing. When using existing intelligent hot air baking equipment, some of the intelligent hot air baking equipment may cause uneven drying effects due to design or technical limitations, and cannot recycle heat, resulting in a waste of resources.

[0003] In order to overcome the above-mentioned defects, a hot air circulation heating baking device can be disclosed with reference to the prior art (application number: 202020462316.3, Chinese patent application date: April 1, 2020). The baking device is provided with a hot air circulation mechanism in the oven shell, which can promote the internal circulation of heat in the oven shell. The first fan drives the air flow through the air collecting hood and then discharges hot air from the upper air outlet plate and the lower air outlet plate to the food placing rack respectively, so as to bake the food on the food placing rack. The negative pressure of the first fan in the return air chamber allows the low-temperature air flow after the baked food to pass through the heating mechanism for reheating and then circulate through the first fan, and enter the oven shell for baking, so as to make the food heated more evenly and significantly improve the efficiency and quality of food baking. This invention is used in the field of cooking equipment; and the prior art (application number: 202220038522. 0, Chinese patent with application date of 2022.01.07) discloses an intelligent dehumidification device for hot air circulation baking, including a baking structure, the baking structure including a baking main unit, the interior of the baking main unit is provided with a hot air circulation structure, the hot air circulation structure includes a hot air circulation structure, the hot air circulation structure is opened on one side and upper and lower ends inside the baking main unit, and a transfer bottom groove is opened at the lower end inside the baking main unit. The utility model arranges a ventilation bottom hole and a transfer bottom groove, and when in use, the hot air is circulated through a hot air circulator, and the hot air flows in the ventilation duct, flows from the ventilation duct to the transfer bottom groove, and is separated and ejected through the ventilation bottom hole, so that the airflow flows more evenly, so that the baking and dehumidification effect is better, and at the same time, the force of the airflow ejection can be reduced to prevent the airflow from blowing the food, which makes it easy for the food to be stacked together, making it difficult to bake and dehumidify the food at the stacking position.

[0004] Although the existing technology can solve the problem of circulating the hot air in the baking equipment, and although a hot air circulation mechanism is set up inside, the hot air of the baking equipment may carry some impurities in the pipeline during the circulation process, such as welding slag, rust, etc. These impurities will also become the source of dust.
