Fig. 1, 2 and 3 are schematic structural views of a cooking appliance. As shown in fig. 2, a cooking appliance includes a cooking chamber 60, a steam degreasing device 50, an auxiliary heating device 70, and a control device 400. The steam degreasing device 50 comprises a steam generating device 502, an external heating device 504 and a nozzle 506, wherein the external heating device 504 is a heating pipe, and the heating pipe is communicated with an outlet of the steam generating device 502 and the nozzle 506. A food placing area 612 is provided in the cooking chamber 60, and the nozzle 506 is provided right above the food placing area 612. As shown in fig. 2, the steam generating device 502 is connected to a water pump 512, the water pump 512 is connected to a water storage container 510, the water pump 512 pumps water in the water storage container 510 into the steam generating device 502, the steam generating device 502 heats the water into steam of about 100 ℃, and the steam is secondarily heated by a heating pipe and then sprayed into the cooking cavity 60 through a nozzle 506. The auxiliary heating device 70 is a hot air device, and may specifically include a fan and a heat-generating pipe.

The steam degreasing device 50 and the auxiliary heating device 70 are matched to form a hot air auxiliary cavity external high-temperature steam degreasing system, so that the steam heated by the steam generating device 502 is reheated, and the steam temperature can be increased to be higher than 120-400 ℃ through reheating. In the cooking process, the high-temperature steam outside the cavity can be independently used for maintaining the cavity temperature or the cavity temperature is maintained through auxiliary heating of a hot air device, and finally the effects of good degreasing, good coloring and good taste are achieved.

Further, compare in not setting up nozzle 506, steam lets in the mode of cooking chamber 60 through the form of gas pocket or spout, and the structure of adding nozzle 506 at the outer high temperature steam conduit of chamber end sprays into cooking chamber 60 with steam through nozzle 506, and steam passes through nozzle 506 and can form certain efflux for steam action distance extension has certain pressure again, and steam action intensity is bigger, more is favorable to the degrease.

Wherein, the cooking process comprises a preheating stage and a steam degreasing stage, and the steam degreasing stage comprises two stages in sequence. As shown in fig. 8, the control method specifically includes:

Step S302: in the first stage of the steam degreasing stage, controlling the steam generating device and the external heating device to work, and enabling the steam degreasing device to convey steam with the temperature higher than or equal to the first temperature to the cooking cavity; and controlling the auxiliary heating device to work so as to maintain the cooking cavity at the fourth temperature.

Step S304: and in the second stage of the steam degreasing stage, controlling the steam generating device and the external heating device to work, so that the steam degreasing device delivers steam with the temperature higher than or equal to the second temperature to the cooking cavity, and the cooking cavity is maintained at the third temperature.

In other words, the cooking process includes three stages, as shown in fig. 14. The preheating stage is the first stage, the first stage of the steam degreasing stage is the second stage, and the second stage of the steam degreasing stage is the third stage. It is to be understood that the straight line segments of the temperature in fig. 14 only illustrate the relative high and low of the temperature in different time periods, and do not indicate that the temperature is kept constant at a certain time period.

As shown in fig. 13, the control method specifically includes:

step S802: preheating the cooking cavity through an auxiliary heating device, and injecting water into the water box;

step S804: pumping water through a water pump;

step S806: heating water to 100 ℃ steam by a steam generating device;

step S810: delivering steam to the heating pipe through the steam guide pipe, carrying out secondary heating on the steam, and then spraying the steam into the cooking cavity through the nozzle; and heating by an auxiliary heating device to maintain the temperature of the cooking cavity at 200-230 ℃;

step S812: the steam after secondary heating is directly sprayed to the cavity through the nozzle by the steam generating device and the heating pipe.

Wherein, the hot air device can adopt the maximum power to heat the cooking cavity 60 to the preheating temperature quickly, and shorten the cooking time.

In the preheating stage, the water storage container 510 is filled with water, and the water storage container 510 is specifically a water box. In the second stage, the water pump 512 pumps the water in the water storage container 510 to the steam generating device 502 for heating, the water is heated to steam (about 100 ℃), the steam is delivered to the steam conduit through the outlet of the steam generating device 502 and is connected to the heating pipe, the heating pipe power is 400W-700W (the heating pipe works intermittently, the steam heating pipe works), and the steam generating device 502 power is 600W-1800W. The heated high-temperature steam in the heating pipe reaches the position of the nozzle 506 through the shortest pipeline. The heating pipe is connected with a first temperature control device, and a temperature sensor of the first temperature control device is arranged at the position of the nozzle 506 for spraying steam. The temperature at the nozzle 506 can reach 120 to 400 ℃ and above by switching the heating pipe. The high-temperature steam after the secondary heating is sprayed to the cooking cavity 60, a second temperature control device in the cooking cavity 60 detects the temperature of the cooking cavity 60, if the temperature is lower than the set temperature, auxiliary heating systems such as a hot air device and the like are started to maintain the set temperature of the cavity, and generally the temperature of the cavity in the second stage T2 is maintained at 200-250 ℃. The cooking time length of the second stage (t1+ t2-t1 ═ t2) accounts for 70% -95% of the total cooking time (t1+ t2+ t 3). The hot air device comprises a heating pipe and a fan and is arranged on the rear wall of the cooking cavity. In this stage, the fan keeps the normal open state, is convenient for blow the steam in the culinary art intracavity evenly, improves the distribution uniformity of steam.

No auxiliary heating device is required to assist in maintaining the temperature at this stage.

As shown in fig. 15, the interval that is maintained for a certain time after the temperature reduction trend is the interval that steam is added, because the high-temperature steam outside the cavity is sprayed into the cavity, the high-temperature steam outside the cavity is sprayed in the early stage, the cooking cavity 60 is cooled, the temperature is reduced to about 215 ℃, and the auxiliary heating of the hot air device starts to work. Along with the extension of the working time, the high-temperature steam sprayed in the cavity can maintain the temperature (200-225 ℃) required by the cavity, auxiliary heat is not needed to be added in the process, the cavity is filled with the high-temperature steam, the food materials are wrapped in an all-around mode, oil which is difficult to remove is removed finally, the food materials are colored, and the crackling is formed.

The control method of the embodiment can enable the food defatting rate to be higher, improve the cooking rate, accelerate food to be uniformly colored and finally achieve the mouthfeel of being scorched outside and tender inside. The method can meet the cooking requirement of a consumer on baking or steaming food, reduce the cooking time, improve the cooking effect and realize quick and uniform coloring and crisp formation of the food.

Figure 15 illustrates in particular the cooking profile of a roast patty. Experiments prove that the prepared barbecue cake is high in degreasing and good in taste (good in color, aroma and taste and not greasy), and the food material with high fat is degreased as far as possible on the basis of ensuring good taste.
