Description

Steaming and baking oven

Technical Field

The invention relates to the technical field of kitchen ware, in particular to a steaming and baking oven.

Background

A steam oven is a cooking machine that accommodates food in a closed space and heats and cooks the food. The steam oven is added with a set of steam system on the basis of the traditional steam oven, thereby fusing the functions of baking and steaming, becoming a hotspot for research and manufacture in the field of kitchen electricity, also being an important component of modern kitchen appliances, and bringing scientific experience to the family life of intelligence sharing. However, the existing electric steaming oven or steaming oven, especially the baking tray of the steaming oven, needs to be pushed and pulled into and out of the box body manually, and the degree of automation is low. Thus, during the use of the steaming oven, there are two disadvantages:

firstly, after food steaming and baking are finished, heat-insulating gloves need to be worn manually, the baking tray is stretched into the box body and pulled out manually, when the baking tray is pulled out, a human body is placed on the front side of the electric steaming and baking oven in a close range, high-temperature steam has the risk of scalding operators (such as faces), and meanwhile, the gloves touch food, so that the problem of unhealthy and sanitary is caused;

secondly, because of the offset of the placement positions of the food or the dinner plate in the baking tray, the force is not easy to control when the baking tray is manually pushed and pulled in the box body, so that the dinner plate slides and collides with the baking tray (particularly when the baking tray is just pushed in or pulled out), and the soup in the dinner plate is splashed out.

Based on the drawback that manual push-and-pull overware exists, some steam agers have been developed at present and have realized the drive arrangement of automatic push-and-pull overware through rack and pinion or chain etc. in order to avoid steam to evaporate the interior steam of roast food of steam ager can not too much run out steam ager outside, need install the drive arrangement of above-mentioned type in the box of steam ager, but this oil smoke drive arrangement that can make food evaporate the roast production, in order to guarantee drive arrangement's normal work, need often clean drive arrangement, it is more troublesome.
