Example two:

the present embodiment is different from the first embodiment in that, as shown in fig. 31, the cooking body includes a first steam passage 531 formed at one side of the outer sidewall 502 of the pot core 500, and a second steam passage 532 located above the pot core 500, the first steam passage 531 communicates with the cooking chamber 150 through the second steam passage 532, and the steam flow tumbling in the cooking chamber 150 cuts into the first steam passage 531 in the direction of the outer sidewall 502 along the second steam passage 532.

This embodiment is intended to solve the first technical problem that can not realize heating pot courage lateral wall, and in embodiment one, the steam air current of shower nozzle is in the culinary art chamber 150 of direction, accomplishes pot courage inside wall 501, the heating back of eating the material earlier afterwards, and the steam air current just outwards has discharged, no longer heats, nevertheless overheated steam air current 300 still has certain heat this moment, and direct outwards discharging will be unfavorable for the good utilization of steam heat, also does not benefit to the even heating of pot courage. In the embodiment, for the efficient utilization of the heat of the steam, the steam channel is arranged in the cooking main body, so that the steam can possibly complete the heating of the outer side wall of the pot liner, and the uniform heating of the pot liner is realized.

Generally, as shown in fig. 1 and 31, a steam outlet 160 and an air inlet 130 for discharging steam on the cooking body are both disposed on the lid 120, the nozzle 200 is disposed at the air inlet 130, steam generated by the steam generator 600 is ejected through the nozzle 200 of the air inlet 130 to enter the liner 500 for cooking, and the steam entering from the cooking cavity 150 is discharged through the steam outlet 160 and inevitably reaches above the liner 500, so that the steam is difficult to preferentially enter the first steam channel 531 to heat the outer sidewall 502 of the liner; this embodiment solves this problem well, and on the basis of the first embodiment, the steam from the cooking cavity can enter the first steam passage well.

According to the scheme of the first embodiment, the steam sprayed by the spray head reaches the inner side wall firstly and then reaches the food material, so that the steam flow in the cooking cavity can enter the first steam channel more smoothly under the guiding action of the inner side wall;

more specifically, when the nozzle discharges steam from one side, the steam airflow cuts into the second steam channel at a small angle and then enters the first steam channel, as shown in fig. 32, at this time, the nozzle 200 only sprays steam towards the left side, the steam airflow 300 reaches the left inner side wall 501 first, after being impacted or blocked by the inner side wall 501, the steam airflow changes direction, turns to the food material to reach the right inner side wall 501 of the pot liner 500 along the lower right side, after being impacted or blocked by the right inner side wall 501, the steam airflow 300 changes direction, turns to the top of the pot liner 500 along the upper left side, one-time rolling is completed, and the whole steam airflow 300 turns in an anticlockwise direction; for the same reason, as shown in fig. 33, when the nozzle sprays air to the right, the air will tumble in a clockwise direction.
