As shown in fig. 4 and 15, in a state in which the steam cooking vessel 20 is mounted in place on the base 10, the air inlet joint 21 may communicate with the air outlet joint 12, so that the base 10 can supply steam to the cooking cavity 201 of the steam cooking vessel 20 through the air outlet joint 12, the air inlet joint 21, and the air inlet valve 40, thereby achieving steam cooking. The heat is not completely conducted by the cookware, the hot steam can be fully contacted with the food material directly to reach the surface of the food material, so that the temperature of the food material in each area in the steam cooking container 20 is uniform, the taste of the food material obtained by steam cooking is uniform and stable, and no scorching occurs.

Further, as shown in fig. 12, in the embodiment in which the air outlet connector 12 is provided at the bottom wall of the installation cavity 11 and the air inlet connector 21 is provided at the bottom wall of the steam cooking container 20, the air inlet connector 21 and the air outlet connector 12 can be ensured by the gravity of the steam cooking container 20 itself when the steam cooking container 20 is installed in the installation cavity 11. And the distance between the air inlet joint 21 and the air outlet joint 12 is shorter, so that the structure is simpler, and the risk of air leakage is reduced.

As shown in fig. 2-4 and 13-16, the embodiment in which the air outlet fitting 12 is provided at the side wall of the installation cavity 11 and the air inlet fitting 21 is provided at the side wall of the steam cooking container 20 makes it easy to align the air inlet fitting 21 and the air outlet fitting 12 when the steam cooking container 20 is installed in the installation cavity 11. The steam cooking container 20 is not limited by the height of the space where the cooking utensil 100 is located, and the cooking utensil 100 can be placed in the space with smaller height for cooking, so that the use requirement of a small-sized kitchen can be met.

In some embodiments, the base 10 may be connected to an external steaming device to facilitate the supply of steam to the steam cooking vessel 20 through the base 10, and the steam cooking vessel 20 is simple in structure and easy to take and place; in other embodiments, as shown in fig. 2, the base 10 may be provided with a steam generator 60, an outlet of the steam generator 60 is connected to the air outlet connector 12, the steam generator 60 is operable to generate steam to supply steam to the steam cooking container 20 through the air outlet connector 12, and the cooking appliance 100 itself has a function of generating steam, so that the cooking appliance 100 is more convenient to use without being affected by external environment.

It should be noted that, in the embodiment of the present invention, the air outlet connector 12 may be integrally formed on the base 10, and the air outlet connector 12 and the base 10 may be separate components connected together; it is within the scope of the present invention that the air inlet connector 21 may be integrally formed with the steam cooking vessel 20 as shown in fig. 13 to 16, and that the air inlet connector 21 and the steam cooking vessel 20 may be separate members coupled together as shown in fig. 4 and 12.

In addition, as shown in fig. 2-4 and 12, the steam cooking vessel 20 may include an outer shell 25 and an inner liner 26. The housing 25 may have a receiving cavity 251 and the liner 26 may be located within the housing 25 (i.e., within the receiving cavity 251) and define a cooking cavity 201. The air inlet connector 21 may be disposed on a side wall or a bottom wall of the housing 25, for example, the side wall or the bottom wall of the housing 25 may be provided with a mounting channel, and the air inlet connector 21 is disposed in the mounting channel in a contact fit with an inner wall surface of the mounting channel, so as to reliably fix the air inlet connector 21. In addition, the space between the air inlet joint 21 and the installation passage may be sealed by a sealing ring to prevent external dust, moisture, etc. from entering between the inner container 26 and the outer case 25.

The high-temperature hot steam has the advantages of low density, light weight and ascending hot steam, and the problems that the hot steam cannot effectively cook with food materials at the bottom of the cooking cavity and the steam effectiveness is insufficient exist in the technical scheme that the steam enters the cooking cavity from the top opening of the cooking cavity.

The sealing effect of the flexible piece is good, structures such as a sealing ring for improving the sealing performance are not needed to be additionally arranged, and the flexible piece is easy to process and install.

In other embodiments, the intake passage 42 includes a variable diameter section with an increasing inner diameter, the blocking member 45 is at least partially positioned within the variable diameter section, and the blocking member 45 is capable of sealing contact with an inner surface of the variable diameter section to block the intake passage 42. For example, the blocking member 45 may block the air intake passage 42 under its own weight, and when the steam is introduced, the steam pressure drives the blocking member 45 upward against the weight of the blocking member 45 to communicate with the air intake passage 42.

In some implementations, the plugging member 45 may be a sphere, and the cross section of the reducing section may be circular, so that the reducing section has a tapered inner wall, and when the plugging member 45 moves for multiple times to generate wear, the sphere and the tapered surface can ensure line sealing, so that the sealing is not easy to fail, the air inlet valve 40 has extremely strong slag resistance, the air inlet channel 42 is ensured to be clean, and the service life of components such as a pipeline connected with the air inlet valve 40, the steam generator 60 and the like is prolonged.

The outer surface of the blocking member 45 may include a sealing engagement surface 451, where the sealing engagement surface 451 may be in contact engagement with the sealing surface 422 to achieve a seal between the blocking member 45 and the valve body 41, where the blocking member 45 may block the air inlet channel 42, and where the surface engagement sealing effect is better. And the blocking element 45 can also be limited by the obliquely extending sealing surface 422.
