Description

Technical Field

[0001] The invention relates to a cooking device, in particular to an inner pot steam generating structure of the cooking device. Background Art

[0002] The existing steam generator is mainly used in electric steamers, which are usually placed outside the inner pot. When working, the steam generator generates steam and passes it into the inner pot to cook food. The steam outlet generated by the structure of this steam generator is small, and the air outlet direction is fixed, so it is impossible to cook food in all directions. At the same time, the steam is easy to condense in the pipeline, and too much scale is generated to affect the quality of subsequent steam. Although there is also a heating plate placed on the bottom plate of the inner pot, which can avoid the above problems, it requires careful steam sealing. If the heating plate and the inner pot are welded together, once the heating plate has a maintenance problem, the inner pot will be completely scrapped and cannot be repaired, which is too wasteful. If welding is not used, screws or studs are used to fix the heating plate directly on the inner pot, and this inner pot is used in a steam-microwave all-in-one machine or a steam-bake-microwave all-in-one machine or other cooking equipment with microwave function, the equipment is prone to microwave leakage when working in microwave mode, which brings certain safety hazards. In summary, further improvements need to be made to the inner pot steam generating device of the existing cooking equipment. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an inner pot steam generating structure of a cooking device with an easily disassembled heating plate and capable of effectively preventing microwave leakage, in view of the above-mentioned existing technical status.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: the inner pot steam generating structure of the cooking device includes an inner pot, and is characterized in that: a heating plate reserved hole is opened on the bottom plate of the inner pot, and the heating plate reserved hole has an annular wall extending downward, a choke is installed below the heating plate reserved hole, and the choke is surrounded by the outer periphery of the annular wall, and a heating plate sealed with the inner pot is detachably connected to the bottom of the choke, and the annular wall cooperates with the heating plate to form a water storage cavity at the bottom of the inner pot.

[0005] In order to absorb the leaked microwaves through water, preferably, a water inlet pipe is installed below the bottom plate of the inner tank, and a water inlet hole for connecting the water inlet pipe and the water storage cavity is opened on the annular wall.

[0006] In order to improve the effect of preventing microwave leakage, the bottom of the choke has a first flange extending outward, the heating plate has an outer peripheral wall and a second flange extending outward from the bottom of the outer peripheral wall, and the joint between the first flange and the outer peripheral wall is covered with a metal mesh.

[0007] In order to further improve the effect of preventing microwave leakage, the water inlet pipe is arranged between the first flange and the second flange and wound around the metal mesh. The choke is provided with a through hole connected to the water inlet hole, and the water outlet end of the water inlet pipe is connected to the through hole.

[0008] There may be a variety of sealing structures between the inner tank and the heating plate. Preferably, a sealing ring is provided between the bottom of the annular wall and the heating plate.

[0009] In order to further improve the effect of preventing microwave leakage, the heating plate is attached to the bottom of the choke.

[0010] In order to facilitate the removal of the heating disc, the choke has a stud extending downward, and a mounting hole is opened at the corresponding position of the heating disc. The stud passes through the corresponding mounting hole and is fixed by a nut. In this way, once the heating disc fails, it only needs to be removed without replacing the entire inner tank.

[0011] As a preferred embodiment of any of the above schemes, the choke is welded on the bottom plate of the inner tank.

[0012] Compared with the prior art, the advantages of the present invention are: the steam generating structure of the inner pot of the cooking device is achieved by installing a choke under the reserved hole of the heating plate, and a heating plate sealed with the annular wall is installed at the bottom of the choke, so that microwaves hit the choke structure when leaking out through the gap between the heating plate and the inner pot, thereby effectively preventing microwave leakage; in addition, the heating plate and the inner pot are detachably connected, which is easy to disassemble and repair.

[0018] The present invention is further described in detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 5As shown, the inner pot steam generating structure of the cooking device of this embodiment comprises an inner pot 1, a circular heating plate reserved hole 12 is opened in the center of the inner pot bottom plate 11, the heating plate reserved hole 12 has an annular wall 13 extending downward, and a water inlet hole 14 is opened on the annular wall 13. The choke 2 is installed below the heating plate reserved hole 12, the choke 2 surrounds the outer periphery of the annular wall 13 and leaves a gap 8 between the choke 2 and the annular wall 13, and the choke 2 is welded and fixed on the inner pot bottom plate 11.

[0020] The heating plate 3 is installed and abutted against the bottom of the choke 2, and a sealing ring 5 is installed between the bottom of the annular wall 13 and the heating plate 3, so that the heating plate 3 is sealed with the inner tank 1 to prevent water and steam leakage. The installation structure of the heating plate 3 is as follows: the choke 2 has a stud 23 extending downward, and a mounting hole 33 is opened at the corresponding position of the heating plate 3. The stud 23 passes through the corresponding mounting hole 33 and is fixed by a nut 7, so that the heating plate 3 is easy to disassemble and clean. After the heating plate 3 is installed, the annular wall 13 of the inner tank 1 cooperates with the heating plate 3 to form a water storage chamber 15 at the bottom of the inner tank 1.

[0021] In addition, the bottom of the choke 2 has a first flange 21 extending outward, the heating plate 3 has an outer peripheral wall 31 and a second flange 32 extending outward from the bottom of the outer peripheral wall, and the joint between the first flange 21 and the outer peripheral wall 31 is covered with a flexible metal mesh 6. The water inlet pipe 4 is arranged between the first flange 21 and the second flange 32 and is wound around the metal mesh 6. The choke 2 is provided with a through hole 22 connected to the water inlet hole 14, and the water outlet end of the water inlet pipe 4 is connected to the water storage chamber 15 through the through hole 22 and the water inlet hole 14. In this way, the water flowing out of the water inlet pipe 4 can enter the water storage chamber 15 through the through hole 22 and the water inlet hole 14 in turn, and wait for the heating plate 3 to heat and evaporate. In addition, the water entering in this way can effectively absorb the leaked microwaves.

[0022] When the steam generating structure is used in a cooking device with micro functions, the microwave leakage prevention effect is achieved through the following four-layer structure: first, the choke 2 is welded to the bottom of the inner pot 1, forming a first layer of microwave leakage prevention structure; second, the heating plate 3 is assembled on the bottom of the choke 2 and connected to the choke 2 with a nut 7, and the heating plate 3 fits the bottom of the choke 2 to form a second layer of microwave leakage prevention structure; third, the metal mesh 6 provided at the seam between the heating plate 3 and the outer periphery of the choke 2 forms a third layer of microwave leakage prevention structure; fourth, the water inlet pipe 4 provided outside the metal mesh 6 is not only used for water inlet, but also can absorb residual microwaves to form a fourth layer of microwave leakage prevention structure.
