Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cooking utensils, and particularly relates to a double-cavity cooking utensil. BACKGROUND

[0002] Two different cooking modes are combined on one utensil, which not only enables users to freely select a desired cooking mode according to different cooking requirements, but also improves the space utilization of a kitchen. However, the double-cavity multi-cooking-mode cooking utensil needs to ensure the independence of respective heating, and therefore needs to be equipped with multiple sets of heating devices, which increases the manufacturing cost of the cooking utensil. In addition, in order to enable the cooking of different modes to work independently and not interfere with each other, the design of the double-cavity cooking utensil becomes more complex, which further leads to an increase in the volume of the cooking utensil and the occupation of a larger kitchen space. SUMMARY

[0003] The utility model provides a double-cavity cooking utensil, which aims to solve the problem of the complicated heating function structure of the double-cavity multi-mode cooking utensil in the prior art, which not only increases the manufacturing cost but also increases the volume of the cooking utensil.

[0004] To solve the above technical problems, the utility model adopts the technical scheme that:

[0005] The utility model provides a double-cavity cooking utensil, which comprises a body, a first cavity, a second cavity and a heating cavity.

[0006] Further scheme: the first cavity is surrounded by a first cavity wall, and the first cavity wall comprises a bottom wall; the second cavity is surrounded by a second cavity wall, and the second cavity wall comprises a top wall.

[0007] Based on the above scheme, the first cavity is surrounded by a first cavity wall, and the second cavity is surrounded by a second cavity wall, which not only increases the sealing property of the first cavity and the second cavity respectively, but also enables the first cavity and the second cavity to be independent of each other and not to affect each other.

[0008] Further scheme: the heating cavity is surrounded by the bottom wall of the first cavity wall, the top wall of the second cavity wall and an annular side wall arranged between the bottom wall of the first cavity wall and the top wall of the second cavity wall.

[0009] Based on the above scheme, the heat cavity is surrounded by the bottom wall of the first cavity wall, the top wall and the annular side wall of the second cavity wall, which ensures the sealing of the heat cavity and avoids the heat generated by the heating assembly in the heat cavity from leaking out. In addition, the heat cavity is independently separated from the first cavity and the second cavity, so that the heating assembly can uniformly heat the first cavity and the second cavity synchronously.

[0010] Further scheme: the heating assembly in the heat cavity includes a U-shaped, S-shaped or ring-shaped heating pipe.

[0011] Further scheme: the first cavity is an oven, and the second cavity is a microwave oven; or, the first cavity is a microwave oven, and the second cavity is an oven.

[0012] Based on the above scheme, the oven and the microwave oven are combined on one cooking appliance, improving the functional diversity of the cooking appliance.

[0013] Further scheme: when the first cavity is an oven and the second cavity is a microwave oven, the machine body further comprises an electric heating assembly for providing heat to the first cavity and a microwave assembly for providing heat to the second cavity.

[0014] Based on the above scheme, the electric heating assembly provides heat for the oven, and the microwave assembly provides heat for the microwave oven. The electric heating assembly and the microwave assembly work independently of each other, ensuring the independence of using the oven and the microwave oven for cooking.

[0015] Further scheme: the first cavity is surrounded by a first cavity wall, and the first cavity wall comprises a side wall;

[0016] The electric heating assembly comprises an electric heater and a fan; the electric heater is arranged inside the first cavity wall and above the first cavity; the fan is arranged outside the first cavity wall, and the side wall of the first cavity wall is provided with a ventilation hole; the fan generates wind which enters the first cavity through the ventilation hole.

[0017] Based on the above scheme, since the heat cavity is located between the first cavity and the second cavity, when the first cavity is an oven, the electric heater is arranged above the first cavity, which can work together with the heating pipe located below the first cavity to provide heat for the first cavity, and the structure distribution is reasonable.

[0018] Further scheme: the second cavity is surrounded by a second cavity wall, and the second cavity wall comprises a bottom wall;

[0019] The microwave assembly includes a magnetron, a waveguide, and a microwave stirrer; the magnetron is disposed outside the wall of the second cavity; a microwave through-hole is provided on the bottom wall of the second cavity; the waveguide is disposed outside the wall of the second cavity, with one end of the waveguide connected to the magnetron and the other end connected to the microwave through-hole; the microwave stirrer is disposed inside the second cavity, below and close to the microwave through-hole.

[0020] Based on the above scheme, since the heating cavity is located between the first cavity and the second cavity, when the second cavity is a microwave oven, the microwave through hole is set below the second cavity, so that the microwave generated by the magnetron enters the second cavity from below to provide heat to the second cavity, and the structural distribution is relatively reasonable.

[0021] A further embodiment: When the first cavity is a microwave oven and the second cavity is an oven, the machine body is further provided with a microwave component that provides heat to the first cavity and an electric heating component that provides heat to the second cavity.

[0022] A further embodiment: the first cavity is surrounded by a first cavity wall, the first cavity wall including a top wall; the second cavity is surrounded by a second cavity wall, the second cavity wall including a side wall.

[0023] The microwave assembly includes a magnetron, a waveguide, and a microwave stirrer; the magnetron is disposed outside the wall of the first cavity; a microwave through-hole is provided on the top wall of the first cavity; the waveguide is disposed outside the wall of the first cavity, with one end of the waveguide connected to the magnetron and the other end connected to the microwave through-hole; the microwave stirrer is disposed inside the second cavity, above and close to the microwave through-hole;

[0024] The electric heating assembly includes an electric heater and a fan; the electric heater is disposed inside the wall of the second cavity and located below the first cavity; the fan is disposed outside the wall of the second cavity, and a ventilation hole is provided on the side wall of the second cavity, through which the air generated by the fan enters the second cavity.

[0025] Based on the above scheme, since the heating cavity is located between the first cavity and the second cavity, when the first cavity is a microwave oven and the second cavity is an oven, the microwave through hole is located above the first cavity, so that the microwaves generated by the magnetron enter the first cavity from above and provide heat to the first cavity; the electric heater is located below the second cavity and together with the heating tube above the second cavity, it provides heat to the second cavity, and the structural distribution is relatively reasonable.

[0026] The beneficial effects of this utility model are as follows:

[0027] In the utility model, first cavity above the machine body, second cavity below the machine body, and heating cavity between the first cavity and the second cavity are separated from each other, and the heating assembly in the heating cavity can heat the first cavity above and the second cavity below simultaneously. One set of the heating assembly can heat the first cavity and the second cavity simultaneously, and can ensure that the heating assembly provides relatively uniform heat to the first cavity and the second cavity. This structure design not only saves manufacturing cost, but also has relatively simple structure, does not need additional heating assembly, and can further reduce the volume of the cooking utensil.
