Description

TECHNICAL FIELD

[0001] The present application relates to an integrated cooker, in particular to a cooking machine combined with a sterilization cabinet and a cooker. The present application also relates to a control method of the cooking machine. BACKGROUND

[0002] Combination is the development direction of future cooking equipment. The combined cooking equipment has the advantages of small kitchen space occupation and convenient use. The existing combined cooking machine generally combines the cooker and the steamer or the oven or the dishwasher or the sterilization cabinet. Among them, the combined cooking machine integrating the cooker and the sterilization cabinet is called the cooker-sterilization combined cooking machine. For example, the utility model patent No. ZL201220717647.2 (authorized publication No. CN203073720U) discloses an integrated cooker, which comprises a base, a sterilization cabinet arranged above the base, and a cooking table located above the sterilization cabinet.

[0003] At present, the sterilization cabinet module and the cooker module in the cooker-sterilization cooking machine are connected together through a communication interface, and the sterilization cabinet function and the cooker function are independently operated. The flame temperature of the cooker is as high as about 1000 degrees, and the temperature near the combustion chamber on the surface of the cooker is about 300 degrees. The sterilization cabinet adopts a sterilization mode combining ultraviolet rays, ozone and temperature. Ozone is generated by ultraviolet irradiation of an ultraviolet lamp (185 nm ultraviolet rays ionize and recombine oxygen molecules to generate ozone).

[0004] Ozone is a high-activated oxygen atom combined with oxygen molecules, which has active chemical properties, unique molecular structure and spectral absorption characteristics, and is easy to be decomposed. At room temperature, the natural decomposition rate is slow; in a high-temperature and humid environment, the decomposition is accelerated; when the temperature is higher than 100 degrees, the decomposition is violent, and when the temperature is about 270 degrees, ozone will immediately decompose into oxygen. Under the same volume, the oxygen content of ozone is higher than that of oxygen, and the combustion-supporting effect of ozone is obviously higher than that of oxygen and air.

[0005] After the ozone sterilization process is completed, a large amount of ozone is left in the sterilization cabinet. At present, the sterilization cabinet product can decompose ozone by drying tableware and temperature assistance. Since the sterilization cabinet generates heat through electric heating components, lacks a circulation system, and the heat is increased by natural diffusion to increase the temperature in the sterilization cabinet, the temperature in the sterilization cabinet is slowly increased, the temperature is uneven, the tableware drying time is long, the ozone decomposition is slow, and a long time is needed to meet the ozone leakage standard.

[0014] The technical solution adopted by the present application to solve the second technical problem is a control method for a combined cooking machine using a stove and a sterilizer, wherein the sterilizer is provided with a heater and has an air inlet that can be opened and closed, and the control method comprises the following steps:
