[0001] The utility model relates to a kitchen cooking utensil, in particular to a multifunctional combined household cooking utensil. Background Art

[0002] There are many types of kitchen cooking appliances, including pressure cookers, induction cookers, steamers, electric hot pots, air fryers, etc. Each of the existing kitchen cooking appliances has its own characteristics and can only be used alone.

[0003] Currently, some have developed multifunctional air fryers. For example, a Chinese invention patent application numbered CN202210031928.0 (publication number CN114287810A), titled "A Multipurpose Air Fryer," discloses an air fryer structure comprising a pot body, a first heating chamber, a heat dissipation chamber, and a second heating chamber, the first, heat dissipation, and second heating chambers being arranged in sequence along the height of the pot body. A first heating assembly and a first impeller are disposed at the bottom end of the first heating chamber, and the bottom wall of the first heating chamber forms a heating portion. The first impeller is configured to direct heat to the heating portion during rotation. A second heating assembly and a second impeller are disposed within the second heating chamber, the second heating assembly being configured to heat air within the second heating chamber. The second impeller is rotatably mounted within the second heating chamber. An air inlet is disposed on the sidewall of the heat dissipation chamber. A drive member and a heat dissipation fan are disposed within the heat dissipation chamber, the drive member being configured to drive the heat dissipation fan, the first impeller, and the second impeller to rotate. This air fryer structure can be used for frying, steaming, or deep-frying, achieving multifunctionality.

[0004] Although the aforementioned air fryer has multiple functions, the first heating chamber, the heat dissipation chamber and the second heating chamber are arranged as an integral whole and cannot be separated and used independently. The use of the product is limited, and the overall size and weight of the product are large, heavy, and inconvenient to store and carry. Moreover, the upper heating position is higher, that is, the cooking position is higher, which is inconvenient to use.

[0005] Therefore, designing a flip-top air fryer with a simpler and more reasonable structure and a steaming function is a technical problem that needs to be solved by those skilled in the art.

[0006] Utility Model Content

[0007] The technical problem to be solved by the present invention is to provide a multifunctional combined household cooking device with a simpler and more reasonable structure and main parts that can be detached and combined into different usage modes in view of the current status of the prior art.

[0008] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a multifunctional combined household cooking device, characterized in that it includes a heating base, a pot body and a heating head that are independent of each other, the pot body has a cooking cavity with an upward opening, a first electric heating device is provided in the heating base, and a second electric heating device is provided in the heating head, the first electric heating device and the second electric heating device are independent of each other, the bottom of the pot body can be placed on the heating base, and the cooking cavity therein can be heated by the first electric heating device, the heating head can be covered on the top of the pot body and cover the cooking cavity, and the second electric heating device therein can heat the cooking cavity.

[0009] As a further improvement, the heating base is provided with a first power interface for plugging a power cord to supply power to the first electric heating device, and the heating head is provided with a second power interface for plugging a power cord to supply power to the second electric heating device. The first power interface and the second power interface can be matched with the same power cord. When the heating base is needed, the power cord only needs to be plugged into the first power interface. When the heating head is needed, the power cord only needs to be plugged into the second power interface. Therefore, the cooker only needs one power cord. In addition, the power cord can be detached from the heating base or the heating head during packaging, which is convenient for storage. Of course, a non-detachable power cord can also be directly set on the heating base and the heating head. The power cords of existing air fryers are all set at the bottom of the pot body, and there is no power cord set on the top of the heating head.

[0010] Alternatively, the first electric heating device may be an electric heating tube type heating structure, an electromagnetic cooker type heating structure, or a microcrystalline heating structure, and a temperature control panel or button may be provided at the front end of the heating base. Of course, the first electric heating device may also be other existing electric heating structures.

[0011] Preferably, the second electric heating device is an air fryer-type heating structure, comprising a motor, a cooling fan, a heat circulation fan, and a heating tube, wherein the cooling fan and the heat circulation fan are both connected to the output shaft of the motor; and the heating head is further provided with a control knob or a control panel, so that the heating head and the pot body are used together to form an air fryer.

[0012] As a further improvement, concave-convex retaining structures are provided between the top of the heating base and the bottom of the pot body, and between the bottom of the heating head and the top of the pot body. These retaining structures between the heating base and the pot body help the pot body rest relatively stably on the heating base, making it difficult for the two to separate, thus forming a relatively stable electric steamer. The retaining structures between the heating head and the pot body also help the heating head rest relatively stably on the top of the pot body, making it difficult for the two to separate, thus forming a relatively stable air fryer.

[0013] As a specific implementation of the concave-convex positioning structure between the heating base and the pot body, the heating base has a first arched positioning boss on the top, and the pot body has a first positioning recess on the bottom that matches the first positioning boss. When the pot body is placed on the heating base, the first positioning boss snaps into the first positioning recess. Of course, the first positioning boss can also be provided on the bottom of the pot body and the first positioning recess on the top of the heating base.

[0014] As an improvement, the first electric heating device is constrained within the heating base and can float up and down. The first electric heating device is supported by a spring, which ensures that the heating surface of the first electric heating device tends to extend beyond the top surface of the first positioning boss. This spring supports the first electric heating device, maintaining its tendency to extend beyond the top surface of the first positioning boss, allowing the heating device to be fully close to the pot body, achieving a better heating effect.

[0015] As a specific implementation of the concave-convex positioning structure between the heating head and the pot body, the pot body has a second, annular, arched positioning boss on the top, and a second positioning recess on the bottom of the heating head that matches the second positioning boss. When the heating head is placed on the top of the pot body, the second positioning boss snaps into the second positioning recess. Of course, the second positioning boss can also be located on the bottom of the heating head and the second positioning recess on the top of the pot body.

[0016] As an improvement, a sealing ring is provided on the bottom surface of the heating head. When the heating head is placed on top of the pot body, the sealing ring forms a seal with the opening of the pot body. When the heating head and pot body are used together as an air fryer, the sealing ring forms a good seal between the heating head and pot body, enhancing the heating effect of the air fryer.

[0017] In a further improvement, the pot body comprises a base and a pot body. The base is composed of an outer shell and an inner pot fixed together. An insulating space is formed between the inner peripheral wall of the outer shell and the outer peripheral wall of the inner pot. The inner pot has a through-hole, and the pot body is removably placed in the placement hole. The top of the pot body has a flange that rests on the top surface of the inner pot. The inner cavity of the pot body constitutes the cooking cavity. The provision of the insulating space prevents the outer surface of the pot body from being hot during use. The pot body is removably placed in the placement hole. The top of the pot body has a flange that rests on the top surface of the inner pot, facilitating the placement and removal of the pot body from the base. The through-hole allows the first heating device to directly contact the pot body, thereby more efficiently heating the pot body.

[0018] Compared with the prior art, the advantages of the present invention are that the three major parts of the cooking device, namely the heating base, the pot body and the heating head, are independent of each other and cooperate with each other, and the first electric heating device and the second electric heating device are independent of each other, so that these three parts can be used in combination with each other to form a variety of usage modes. The heating base is combined with the pot body and then combined with a conventional lid to be used as a steamer mode, and the pot body is combined with the heating head to be used as an air fryer mode, and the overall height after the two are combined is not high, which is convenient for placement; in addition, the heating base can be used independently as an induction cooker or an electric stove, and the heating base can be used in combination with a conventional pot or a teapot, expanding a variety of usage modes, thereby making the cooking device have a very wide range of uses.
