The heating device 3 is provided in the main machine 1, and a common heating device 3 is an electromagnetic heating device 3. A magnetic conductive plate is provided in the processing chamber 1a, and the magnetic conductive plate is heated by electromagnetic heating, to heat the magnetic conductive plate. Furthermore, the heat of the magnetic conductive plate is conducted to the heat-conducting liquid in the processing chamber 1a, to heat the processing cup 21.

In other embodiments, electric heating wire heating, infrared heating and other methods may also be used.

In addition, the heat-conducting liquid mainly plays the role of heat-conducting, and it also needs to be edible, such as water, edible oil, etc. For the convenience of description, the heat-conducting liquid is described as water.

The heating of the processing cup 21 may include adding water to submerge the processing cup 21, and heating the processing cup 21 by heating the water, or heating the processing cup 21 by water vapor generated after the water is heated. It is also possible that the water in the processing chamber 1a is directly introduced into the processing cup 21, and the food material in the processing cup 21 are directly boiled, and the above are all embodiments of the present disclosure.

In an embodiment, as shown in FIG. 3, the food material is indicated as b, which is indicated by circular object in the figure, and the water level is indicated by a, which is indicated by dotted lines. The processing chamber 1a contains water to a certain height, and when the processing cup 21 is placed in the processing chamber 1a, the processing cup 21 is at least partially immersed in water, the cooking function of water-proof stew is realized, that is, there is no contact between water and food, and the food can also be cooked, which can reduce the loss of food nutrition and realize the diversification of food cooking.

In an embodiment, a liquid passage hole may be provided in the part of the processing cavity 21a in contact with the water, to realize the circulation of the water in the processing cavity 21a and the processing chamber 1a. The liquid passage hole 211 may be provided at the bottom wall of the processing cavity 21a, on the side wall of the processing cavity 21a, or on the bottom wall and the side wall of the processing cavity 21a at the same time, to introduce the heat-conducting fluid in the processing chamber 1a into the processing cavity 21a, the above are all embodiments of the present disclosure.

In an embodiment, the heat transfer can also be realized in the gaseous state of the heat-conducting liquid. In the embodiment in which the heat-conducting liquid is water, the water has two phases, liquid state and gaseous state, and gaseous water vapor can be used to cook the food material.

It should be noted that for this cooking method, as shown in FIG. 8, FIG. 14 and FIG. 20, the amount of water in the processing chamber 1a can be added less, and it is not necessary to submerge the processing cup 21, as long as steam can be formed, which saves water resources.

For the above cooking method of steaming, steam needs to be introduced into the processing cavity 21a to realize the contact between the steam and the food, and a steam passage is formed in the food processor 100.

The steam passage communicates the processing chamber 1a with the processing cavity 21a, and the heat transfer fluid in the processing chamber 1a is introduced into the processing cavity 21a after a phase change. By steam-cooking the food material in the processing cavity 21a, the food materials are cooked by steaming, to realize the diversification of food cooking.

In some embodiments of the present disclosure, without limiting the specific introduction route of the steam, a steam passage may be formed between the processing cup 21 and the processing chamber 1a. It is also possible to form a steam passage directly on the processing cup structure 2. It is also possible that a steam passage is formed between the processing cup 21 and the processing chamber 1a. A steam passage is also formed at the processing cup structure 2. The above are all embodiments of the present disclosure.

In an embodiment, as shown in FIG. 12 to FIG. 17, the steam passage is partially formed between the processing cup structure 2 and the processing chamber 1a, and is partially formed at the processing cup structure 2. That is, the gap between the processing cup 21 and the processing chamber 1a is configured to guide the airflow into the processing cavity 21a, to realize the communication of airflow between the two cavities.

In an embodiment, a first air passage hole 212 is formed through an outer side wall of the processing cup 21 at an upper end. A first annular air passage gap 22 is formed between the outer side wall of the processing cup 21 and an inner side wall of the processing chamber 1a.

The steam passage includes the first annular air passage gap 22 and the first air passage hole 212.

That is, the steam flow enters the first air passage hole 212 from the first annular air passage gap 22, and is introduced into the processing cavity 21a through the first air passage hole 212. The flow of the steam between the two cavities is realized, and by arranging the first air passage hole 212, the structure is simple, and it is convenient to quickly realize the diversion of the steam.

In some embodiments of the present disclosure, the specific number of the first air passage holes 212 is not limited, for example, it can be 2, 3, 4, 5, 6, or the like. The arrangement of the plurality of first air passage holes 212 is also not limited, which can be spaced apart along the circumferential direction of the processing cup 21, so that the steam flow in the first annular air passage gap 22 can evenly enter the processing cavity 21a from the circumferential direction, to realize the uniform circulation of steam.

In an embodiment of the present disclosure, the cross-sectional form of the first air passage hole 212 is not limited, for example, it may be a circular hole, a square hole, a rectangular hole, or the like.

The first gas passage hole 212 is provided at the upper end of the side wall of the processing cavity 21a, and the steam will directly enter the upper end of the processing cavity 21a. In order to guide more airflow to blow on the food material at the bottom, it is necessary to drain the steam airflow entering the processing cavity 21a. In an embodiment, from the outside to the inside, the first air passage holes 212 are inclined downward, that is, the airflow will enter the processing cavity 21a in a downward direction, and more steam contacts with the food material, which is convenient for sufficient heating of the food material.

The inclination angle of the first air passage hole 212 is not limited, for example, it can be any angle between 90° and 0°, for example, 89°, 88°, 87°, 86°, 85°, 84°, 83°, 82°, 81°, 80°, or the like, and can also be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or the like. The above integer degrees are all within the scope of the present disclosure. Fractional degrees between any two integer degrees described above are also within the scope of the present disclosure.

In an embodiment, it is also possible to install a guide tube obliquely downward in the processing cavity 21a, and the outlet of the guide tube is further directed downward to further guide the airflow to the bottom of the processing cavity 21a, to achieve further guide flow. The mounting of the guide tube cannot affect the stirring in the processing cavity 21a.

In another embodiment, it is also possible to set a flow guide structure in the processing cavity 21a. As shown in FIG. 16 and FIG. 18, an annular drainage baffle 23 is provided in the processing cavity 21a, and the upper end of the annular drainage baffle 23 is provided at a top wall surface of the processing cavity 21a. A lower end of the annular drainage baffle 23 is spaced from a bottom wall of the processing cavity 21a to form a second annular air passage gap 231 communicating with the first air passage hole 212 between the outer side wall of the annular drainage baffle 23 and the inner side wall of the processing cavity 21a, to guide the steam flow to the bottom of the processing cavity 21a. That is, the steam flow introduced from the first air passage hole 212 is above the processing cavity 21a, then, the steam flow is fully in contact with the food material entering the bottom of the processing cavity 21a and the bottom wall of the processing cavity 21a in the second annular air passage gap 231, then, the steam flow rises from the bottom of the processing cavity 21a to the entire processing cavity 21a, to fully stew the food material in the processing cavity 21a.

The length of the annular drainage baffle 23 directly determines the depth to which the steam can be introduced into the processing cavity 21a. Setting the annular drainage baffle 23 as long as possible can limit the distance between the lower end surface of the annular drainage baffle 23 and the bottom wall surface of the processing cavity 21a, which can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm and so on.

The arrangement of the plurality of first ventilation holes is also not limited, which can be spaced apart along the circumferential direction of the annular drainage baffle 23, so that the steam flow in the second annular air passage gap 231 can evenly and fully contact the food material at different heights from the circumferential direction, to facilitate uniform curing.

The annular drainage baffle 23 may be disposed on the side wall of the processing cavity 21a, or may be disposed on the top wall of the processing cavity 21a.

That is, the annular drainage baffle 23 is provided at the lower end of the cup cover assembly 214. When the cup cover assembly 214 is separated from the cup body 213, the annular drainage baffle 23 is also taken out from the cup body 213, and it is convenient for the packing of food material. In addition, there is no need to provide a sealing structure on the top of the processing cavity 21a, to reduce the leakage of the steam flow from the top of the processing cavity 21a.

When the cup cover assembly 214 is a plastic part, the annular drainage baffle 23 is also a plastic part, the cup cover assembly 214 and the annular drainage baffle 23 may be integrally formed, for example, injection-molded by the same injection mold.
