Description

Technical Field

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

[0002] The existing steam generator is mainly used in electric steamers, which are usually arranged 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, which cannot cook food comprehensively. 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 structure in which the heating plate is placed on the bottom plate of the inner pot, which can avoid the above problems, the steam sealing structure needs to be carefully designed. 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, which is too wasteful. If it is not welded, but the heating plate is fixed with screws or studs, it is impossible to prevent microwave leakage in the steam-microwave all-in-one machine or the steam-bake-microwave all-in-one machine, which will bring safety hazards. In addition, it is difficult to clean the scale of the external steam generator, and a return water system needs to be added, which is costly. In summary, further improvements need to be made to the existing steam generating device. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a steam generating structure of a cooking device which has the functions of sealing steam and 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 technical problems is: the steam generating structure of the cooking equipment includes an inner pot, which is characterized in that: a mounting hole is opened on the bottom plate of the inner pot, a heating plate is installed in the mounting hole, an annular groove surrounding the mounting hole is formed on the bottom plate of the inner pot, a sealing ring is installed in the annular groove, the sealing ring is sleeved on the heating plate, a liquid outlet hole connected to the inner cavity of the inner pot is opened on the heating plate, a liquid inlet pipe is installed below the heating plate, and the liquid outlet of the liquid inlet pipe is connected to the liquid outlet hole.

[0005] In order to provide a better sealing connection structure between the sealing ring and the heating plate, the inner circumference of the sealing ring has a groove for the heating plate to be inserted into.

[0006] In order to facilitate the disassembly and assembly of the heating plate, the inner wall top of the annular groove forms a step extending radially inward, and the heating plate is detachably connected to the step. In this way, once the heating plate fails, it only needs to be disassembled without replacing the entire inner tank.

[0007] In order to improve the effect of preventing microwave leakage, an annular aluminum foil strip is sandwiched between the heating plate and the step.

[0008] In order to further improve the effect of preventing microwave leakage, the liquid inlet pipe is located below the aluminum foil strip, and a metal mesh gasket is also provided below the aluminum foil strip. The outer periphery of the metal mesh gasket is clamped between the step and the liquid inlet pipe, and the inner periphery of the metal mesh gasket is clamped between the aluminum foil strip and the liquid inlet pipe.

[0009] In order to fix the liquid inlet pipe, a metal pressing plate for pressing the liquid inlet pipe is installed below the liquid inlet pipe.

[0010] In order to ensure that each microwave seal can be not only compressed but also easy to disassemble, corresponding upper and lower through holes are opened on the heating plate, the step of the inner pot, the metal mesh gasket, the liquid inlet pipe and the metal pressure plate, and the outer periphery of the heating plate has downwardly extending studs, which pass through the through holes in sequence from top to bottom and are locked by nuts.

[0011] In order to facilitate the backflow of condensed water, the mounting hole is arranged in the center of the inner pot bottom plate, and the inner pot bottom plate gradually tilts downward from the outer periphery to the mounting hole. The upper surface of the heating plate is recessed downward to form a liquid receiving cavity, and the liquid outlet hole is arranged in the liquid receiving cavity. In addition, the outer edge of the heating plate is lower than the upper edge of the outer wall of the annular groove.

[0012] In order to enable the water in the liquid inlet pipe to absorb microwaves, the liquid inlet pipe is a conductive silicone tube.

[0013] Preferably, the mounting hole is a circular hole, and correspondingly, the annular groove is a circular groove, and the heating plate is a circular plate.

[0014] As a preferred embodiment of any of the above solutions, a heating tube is installed at the bottom of the heating plate.

[0015] Compared with the prior art, the advantages of the present invention are: the heating plate of the steam generating structure of the cooking equipment is installed on the inner pot, and the heating plate and the bottom plate of the inner pot are sealed by a sealing ring to prevent steam leakage. In addition, the liquid inlet pipe can not only inject water into the heating plate, but the water in the heating pipe can also absorb microwaves, thereby preventing microwave leakage, solving the problem of microwave leakage at the contact point between the heating plate and the inner pot sheet metal.
