Description

[Technical Field]

[0001] The present invention relates to the technical field of kitchenware, and more particularly to a microwave cooking pan. [Background technology]

[0002] Microwave cooking pots utilize a microwave-absorbing layer on the surface of the pot to absorb microwaves and heat the pot itself, allowing for cooking by grilling or frying food from the outside. This has led to an increase in the types of cooking utensils that heat food internally in microwave ovens, broadening the range of microwave heating appliances used. When using metal cooking utensils in a microwave oven, insulating elastic materials are typically used to insulate and protect them from sparks caused by contact between the metal and microwaves. However, there is a slight gap between the insulating elastic material and the metal, which generates a certain amount of hot gas during the heating process, requiring consideration for gas evacuation. The hot gas can easily cause problems such as deformation or swelling of the insulating case.

[0003] Patent Document 1 discloses a microwave grill plate that includes a parallel-connected container and a heating element, the container and heating element being stacked in order inside an insulating case, the container having an open structure, the heating element being provided with a microwave absorbing layer, and pressure relief holes drilled on both the front and back of the insulating case for discharging gas from the top of the container. The pressure relief holes in this technical solution only serve to discharge high-temperature gas generated by heating food materials, thereby balancing the internal cavity of the grill plate with the external air pressure. However, the air trapped in the gap between the insulating case and the container cannot be discharged even after expanding due to heat, causing the insulating case to bulge or fall off, affecting the user experience and safety.

[0004] [Patent Document 1] China Utility Model Registration No. CN202021038487.X Summary of the Invention [Problem to be solved by the invention]

[0005] The purpose of this invention is to provide a microwave cooking pot that solves the problem of the air in the gap between the insulating case and the container expanding due to heat and then not being able to escape, resulting in deformation and swelling of the insulating case, which affects the user experience and safety, and overcomes the shortcomings of the prior art. [Means for solving the problem]

[0006] The technical means of this invention is a microwave cooking pot comprising an outer case, a metal inner pot, and an inner pot microwave absorbing layer, in which the outer case is covered on the outside of the metal inner pot, the metal inner pot and the outer case are integrally molded, and there is no gap or exhaust port between the metal inner pot and the outer case.

[0007] The outer case is made of silicone rubber, and the outer case and the metal inner pot are integrally molded by vulcanization molding, or the outer case is made of soft plastic, and the outer case and the metal inner pot are integrally molded by injection molding, or the outer case is made of ceramic.

[0008] The microwave cooking pot further comprises a pot lid having a pot lid base, a pot lid microwave absorbing layer, and a pot lid top lid, the pot lid top lid being made of plastic or silicone rubber, the pot lid base being made of metal, the pot lid base and the pot lid top lid being assembled in a snap-fit ​​manner, and the pot lid microwave absorbing layer being affixed to the upper surface of the pot lid base.

[0009] The microwave cooking pot further comprises a pot handle.

[0010] The pot handle is integrally formed with the outer case.

[0011] The pot handle is engaged with the outer periphery of the outer case by a structure with a locking ring.

[0012] The locking ring has ribs on the inside thereof to form an interference fit between the locking ring and the outer case. [Effects of the Invention]

[0013] Because this device is manufactured using a one-piece molding method, there is no gap between the metal inner pot and the outer case, which prevents the occurrence of phenomena such as deformation or swelling of the outer case due to high-temperature gas generated in the gap between the metal inner pot and the outer case.

[0015] The technical solutions of the present application will be clearly and completely described below with reference to the drawings. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative effort will fall within the scope of protection of the present invention.

[0016] (First embodiment) 1 to 3, this microwave cooking pot comprises an outer casing 1, a metal inner pot 2, an inner pot microwave absorbing layer 21, a pot lid base 3, a pot lid microwave absorbing layer 4, and a pot lid top lid 5. The microwave absorbing layer is first applied to the metal inner pot, and then the outer casing and metal inner pot are joined together using an integral molding method, eliminating any gaps between the outer casing and the metal inner pot and preventing the generation of high-temperature gas during microwave heating. The outer casing is made of silicone rubber, plastic, or ceramic, and is integrally molded using vulcanization molding or injection molding. The outer casing and pot handle are molded as a single unit, and the pot lid is composed of three parts: the pot lid base 3, the pot lid microwave absorbing layer 4, and the pot lid top lid 5.

[0017] The metal inner pot 2 has an upper edge 20, and since the diameter of the upper edge 20 is larger than the maximum diameter of the round pot-shaped metal inner pot main body, a step 201 is formed at the connection point between the upper edge and the metal inner pot main body, and a pair of handles are integrally molded on the top of the outer case, and the handles are located outside and below the step 201.

[0018] (Second embodiment) Referring to Figures 4 to 6, this microwave cooking pot comprises an outer case 1, a metal inner pot 2, an inner pot microwave absorbing layer 21, and a pot handle 71, wherein the outer case 1 and the metal inner pot 2 are joined by an integral molding method, while the pot handle 71 and the outer case 1 are designed as separate entities and molded individually, the pot handle is equipped with a locking ring 7, and the pot handle 71 and the locking ring 7 are integrally molded, with a rib 72 provided on the inside of the locking ring 7 to form a tight fit between the locking ring and the outer case.

[0019] In this embodiment, the upper opening of the outer case 1 reaches the step 201 at the connection between the upper edge 20 of the metal inner pot 2 and the metal inner pot main body, and a thick portion 22 that compresses the rib 72 is provided at the upper opening of the outer case 1, and the top edge of the locking ring 7 is pressed against the step 201, so that the locking ring does not easily come off from the integrally molded metal inner pot and outer case.

[0020] The other structures are the same as those in the first embodiment, so detailed explanations thereof will be omitted here.

[0021] (Third embodiment) 7 to 9, the pot handle 81 and the outer case 1 are designed and molded separately, and the pot handle is equipped with a locking ring 8, which is integrally molded with the pot handle. The locking ring 8 has a rib 82 on the inside, which forms an interference fit between the locking ring and the outer case. The top edge of the locking ring 8 is pressed against the step 201.

[0022] The other structures are the same as those in the first embodiment, so detailed explanations thereof will be omitted here. [Explanation of symbols]
