The steam in the chamber 6 can enter the second steam passage 510 and enter the receiving chamber 3 from the opening at the upper end of the second steam passage 510, whereby the steam can be directed to the lower portion of the inner tank 1 and the second steam passage 510. The inner side wall is heated.

Thereby, the steam generated in the steam generator 4 can be guided to the inner tank 1 through the first steam passage 500 and the second steam passage 510, by heating the lower portion of the inner tank 1 and the side wall of the second steam passage 510. The purpose of heating the food in the inner tank 1 is achieved, and the steam generated in the steam generator 4 can also enter the accommodating chamber 3 along the second steam passage 510. Preferably, the upper end of the second steam passage 510 can be located. The upper part of the food in the chamber 3 is accommodated, so that the steam can flow above the food to heat the food from above the food, thereby further reducing the temperature gradient difference of the food in the inner liner 1 from bottom to top, thereby The food in the inner tank 1 can be cooked at the same time, and the softness and hardness of the cooked food are also basically the same, so as to achieve the purpose of improving the taste of the food, so as to better meet the user's use requirements.

In a specific example of the present invention, as shown in FIG. 3, the outlet of the first steam passage 500 is connected to the outer bottom wall of the inner liner 1, and the outer bottom wall of the inner liner 1 is enclosed with the outlet of the first steam passage 500. a vapor storage chamber 6 and the vapor storage chamber 6 communicates with an opening at a lower end of the second steam passage 510 such that the vapor in the vapor storage chamber 6 faces the outer bottom wall of the inner liner 1 and the inner side wall of the second steam passage 510 It is heated and enters the accommodating chamber 3 from the opening at the upper end of the second steam passage 510.

Thereby, the steam generated by the steam generator 4 can enter the steam storage chamber 6 along the first steam passage 500, utilizing the steam in the steam storage chamber 6 to the outer bottom wall of the inner liner 1 and the inner side of the second steam passage 510. The wall is heated while the steam is heated above the food in the accommodating chamber 3 to heat the food, thereby better reducing the temperature gradient difference of the food in the inner liner 1 from bottom to top, so that the food in the inner liner 1 is simultaneously Cooked and cooked, and ensure that the softness and hardness of the cooked food are basically the same, in order to improve the taste of food, can better meet the user's needs.

Embodiment 4,

The embodiment is substantially the same as the structure of the third embodiment, wherein the same components are given the same reference numerals, except that the structure at the outlet of the first steam passage 500 and the first steam passage 500 and the inner tank 1 are The connection method is different from that of the third embodiment.

As shown in FIG. 4, the outlet of the first steam passage 500 is fitted to the lower portion of the inner liner 1 and connected to the outer side wall of the inner liner 1.
