1. Technical Field

The invention belongs to the technical field of kitchen equipment, and particularly relates to an intelligent-cleaning steam oven liner and an integrated stove.

2. Description of Related Art

At present, food is processed worldwide by frying, stir-frying, deep-frying, steaming, stewing, simmering and roasting, among which steaming and roasting are used most frequently, indicating that these two food processing methods are preferred by people. For example, the most common staple foods, rice and steamed breads, are processed by steaming, and barbecued meat which is popular nowadays, such as roasted mutton cubes, is closely related to the roasting process. With the development of economy and the progress of society, people put forward higher requirements for the diversity of foods, leading to higher requirements for food processes. Some foods not only need to be steamed, but also need to be roasted, wherein part of these foods need to be steamed and then roasted, while part of these foods need to be roasted and then steamed. The use of a steamer and an oven to complete the steaming process and the roasting process makes operations discontinuous, leading to low efficiency; and the transfer of foods from one device to another device will result in a negative influence on the quality of foods. Especially, the continuous expansion of the marketization scale in nowadays puts forward high requirements for the production efficiency of any food, and in order to improve the production efficiency, manufacturers consider to integrate the steaming process and the roasting process to one food device, leading to the emergency of steam ovens, which are continuously developed in recent years and have become common kitchenware in modern kitchens.

Integrated stoves, which are of a deep well type or a side suction type, can miraculously suck away cooking fume downwards under the action of a negative-pressure region of fluid generated by exhaust air based on the micro-aerodynamic principle to prevent the cooking fume from being diffused everywhere and can suck away over 95% of the cooking fume. The integrated stove, as an internationally advanced kitchen household appliance developed to solve the problem that traditional range hoods cannot completely eradicate cooking fume and improve the kitchen and home environment, organically integrates a range hood, a stove, a disinfection cabinet and a storage cabinet and completely eradicates kitchen fume, thus completely eliminating the last polluted area of residences and bringing a profound influence on Chinese kitchens characterized by deep-fat stir-frying.
