The steam guide cover and the first steam guide channel can guide the high-temperature steam, reducing heat loss of the steam in the conduction process, and through the isolation of the steam guide cover, the temperature rise of the water tank cover part will not be too high to avoid scalding the user.

[0028] Specifically, the top of the cooking device 2 is provided with an upper shell of the whole machine, the upper side of the upper shell of the whole machine is provided with an inner groove, the water tank 1 can be embedded into the inner groove, the shape of the inner groove matches the shape of the water tank 1, preventing deviation of the installation direction, or positioning structures or marks can be correspondingly arranged on the water tank 1 and the upper shell of the whole machine, the marks can be arrow-shaped and arranged on the water tank cover assembly 11, facilitating installation of the water tank 1.

[0029] As shown in the figure, Figure 2 The water tank cover assembly 11 and the water tank seat assembly 12 are provided with a positioning convex rib 29 on one of them and a positioning groove 26 corresponding to the positioning convex rib 29 on the other, so as to quickly position and assemble the water tank cover assembly 11 and the water tank seat assembly 12, facilitating operation of the user.

[0030] The water tank seat assembly 12 and the tank cover assembly 11 can be combined together through interference fit, and can be separated by force when disassembled, or can be connected through buckling or threaded connection, so as to realize detachable fixing between the two.

[0031] The cooking device 2 can be an air fryer with a steaming function, or a steam oven, which has a steam delivery pipe in communication with the cooking cavity. When the water tank 1 is installed, the steam guide pipe is connected to the steam delivery pipe, and steam can be smoothly introduced into the cooking cavity without the need for a separate steam generator inside the cooking device 2.

[0032] Specifically, a sealing member 17 is arranged between the periphery of the steam guide cover 16 and the water tank seat assembly 12. The sealing member 17 can seal the gap between the periphery of the steam guide cover 16 and the water tank seat assembly 12, preventing steam in the water holding cavity 38 from leaking out of the gap and being discharged only from the guide outlet 31. At least one water tank cover handle 14 can be installed on the upper side of the water tank cover 13 to facilitate lifting or lowering the entire water tank cover assembly 11. The water tank cover 13 and the steam guide cover 16 can be detachably fixedly connected. The edge position of the steam guide cover 16 can be provided with a plurality of vertical clamping plates which are clamped with the clamping blocks on the inner side wall of the water tank cover 13. In this way, the water tank cover 13 and the steam guide cover 16 can be connected integrally, facilitating installation.

[0033] In the present embodiment, as shown in Figure 3 The first steam guide channel includes a guide outlet 31 arranged on the steam guide cover 16 and an adapter pipe 32 installed at the edge position of the steam guide cover 16 for communication with the second steam guide channel. The guide outlet 31 and the adapter pipe 32 are connected by a steam pipe 15.

[0034] Specifically, the steam guide cover 16 is provided with a steam collecting protrusion 28. The steam collecting protrusion 28 has an inner recess cavity in communication with the water holding cavity 38. The guide outlet 31 is arranged on the side wall of the steam collecting protrusion 28. The steam collecting protrusion 28 has a steam collecting effect, which can collect high-temperature steam generated in the water holding cavity 38 in the steam collecting protrusion 28, facilitating continuous output of high-temperature steam in the steam collecting protrusion 28 from the guide outlet 31. The steam pipe 15 can be a silica gel hose, which is convenient to adjust the position. The adapter pipe 32 can be a right-angle adapter pipe, which is detachably installed on the steam guide cover 16.

[0035] In the present embodiment, as shown in Figure 4As shown, the steam guide cover 16 is provided with a fence 34 extending towards the water tank seat assembly 12 and corresponding to the heating element 19, which divides the water holding cavity 38 into a steam area 36 and a non-steam area 37, so as to reduce the boiling area and improve the heating efficiency. The fence 34 can be generally circular and arranged around the heating element 19, and the lower end thereof can extend to a position close to the bottom of the water holding cavity 38, but a gap for water in the non-steam area 37 to enter is required. Boiling occurs in the steam area 36 when the heating element 19 is heated, and high-temperature steam is generated after boiling, which is guided upwards along the fence 34 and discharged from the guide outlet 31. Most of the high-temperature steam does not enter the non-steam area 37, and the bottom of the water holding cavity 38 in the non-steam area 37 can be designed as an inclined surface inclined towards the heating element 19. In this way, water in the non-steam area 37 can continuously enter the position of the heating element 19 when water in the steam area 36 is consumed, so as to improve the heating efficiency. Meanwhile, a plurality of gaps 39 can be arranged at the bottom of the fence 34 at intervals, so that water in the non-steam area 37 can also enter the steam area 36 from the gaps 39, thereby improving the water inlet efficiency.
