Description

Technical Field

[0001] The invention relates to a multifunctional kitchen cooking utensil. Background Art

[0002] As people's quality of life continues to improve, kitchen appliances are becoming more and more abundant, and microwave ovens, ovens, steamers, integrated stoves, etc. have gradually become essential kitchen appliances for family life. These kitchen appliances have relatively simple functions, each product needs to occupy a certain kitchen space, and it costs a lot to buy them separately.

[0003] Therefore, people have developed a cooking appliance that integrates multiple cooking functions, such as a microwave oven with steam and oven. The microwave oven with steam and oven has multiple cooking functions, including microwave mode, microwave steam mode, grill mode, hot air grill mode, and air frying mode. One machine can realize the functions of a microwave oven, steam oven, oven, and air fryer, and is very popular among consumers. Even so, the microwave oven with steam and oven still cannot meet the eating habits of most Chinese people, and its market share in China is relatively low. The reason is that this type of cooking appliance cannot produce satisfactory Chinese food, such as the typical cooking function, as well as other functions such as boiling and stewing. Therefore, the idle rate of the microwave oven with steam and oven is still relatively high.

[0004] A Chinese patent with publication number CN216822949U (patent number CN202122809328.6) discloses an electric oven with a stir-fry function, in which a wok is detachably connected to the furnace of the electric oven, a stirring knife is provided in the wok, and a first rotating shaft connected to the stirring knife, a driving mechanism, and a connecting assembly for detachably connecting the wok and the oven furnace are provided in the oven shell. When in use, the wok is firmly mounted on the oven furnace through the connecting assembly, the wok is heated by the heating device, and the first rotating shaft is driven by the driving mechanism to rotate, thereby driving the stirring knife to rotate in the wok to stir-fry the ingredients in the wok, so that frying, boiling, stewing, etc. can be achieved. In this structure, the connecting assembly includes a first connecting member arranged at the bottom of the frying pan and a second connecting member arranged at the bottom of the oven furnace and can be clamped with the first connecting member. The second connecting member and the first rotating shaft are both protruded and arranged on the lower side of the inner wall of the oven furnace. The arrangement of these two components will affect the flatness of the lower side of the inner wall of the furnace. When the frying pan is not needed, the protruding first rotating shaft and the second connecting member are not conducive to placing food or food containers on the lower side plane of the inner wall of the furnace. In addition, in this structure, a driving mechanism must be separately arranged, and the driving motor in the driving mechanism has a high cost. Therefore, the existing electric oven with stir-frying function needs to be further improved. Summary of the invention

Since the entire cooking module 6 comprises a main body assembly 61 and a pot body assembly 62 that are detachably connected, during the cooking process using the cooking module 6, the pot body assembly 62 and the main body assembly 61 can be installed in place, and then the entire cooking module 6 can be properly placed in the cooking cavity, so that the first connection end 32 is connected to the driving connection end 31; when adding auxiliary materials in the middle, there is no need to take out the main body assembly 61, and only the pot body assembly 62 can be taken out from the cooking cavity to add ingredients or wash it separately, which is more convenient to use.

[0043] In this embodiment, a magnet 627 is provided on the pot cover 622 of the pot body assembly 62, and a Hall sensor 613 is provided on the main body assembly 61. The Hall sensor 613 is provided at a position that satisfies: when the pot cover 622 is correctly covered on the pot body 621, the Hall sensor 613 is relative to the magnet 627 on the pot cover 622 and can detect a signal. The Hall sensor 613 is electrically connected to a power control board provided in the box. An opening is provided on the pot cover 622, and an auxiliary material cavity 628 communicating with the opening is provided above the pot cover 622. A movable partition 629 is provided between the auxiliary material cavity 628 and the opening. The movable partition 629 has a first state in which the opening is connected with the auxiliary material cavity and a second state in which the opening is blocked with the auxiliary material cavity. The movable partition 629 is connected to the steam drive rod 81, which is sealed and movably connected in the piston cavity. The piston cavity is connected to the steam inlet 12 on the rear side of the cooking cavity through a steam pipe 82 arranged in the cooking module. The steam drive rod 81 can drive the movable partition 629 to move under the action of steam, so that the movable partition 629 switches from the second state to the first state. Of course, a reset torsion spring can also be arranged between the movable partition 629 and the pot cover 622. When the steam drive rod 81 is not pushed by steam, the reset torsion spring can switch the movable partition 629 from the first state back to the second state. The auxiliary materials can be put into the auxiliary material cavity 628 in advance. When the auxiliary materials need to be added during cooking, the program controls the steam generation module to generate steam and inject it into the piston cavity. The pressure generated by the steam pushes the steam drive rod 81 to push the movable partition 629 of the auxiliary material cavity open, so that the auxiliary materials fall into the pot body.
