Description

Technical Field

[0001] This utility model belongs to the field of microwave cooking equipment technology, and in particular relates to a metal container heating kit suitable for microwave heating. Background Technology

[0002] Microwave ovens are common household cooking appliances. They work by using microwaves generated by a magnetron to cause polar molecules (mainly water molecules) in food to vibrate and rub against each other under an alternating electric field, generating heat and achieving rapid heating from the inside out. When glass or ceramic containers are used, the electromagnetic waves emitted by the microwave oven pass directly through the container to heat the food. Metal materials reflect microwaves, so food in metal containers is not directly heated. With the widespread use of food delivery and the fast-paced lifestyle, the consumption of canned beverages has continued to rise, resulting in a large number of discarded cans. The traditional belief that metal containers cannot be used in microwave ovens not only limits the use of microwave ovens but also wastes resources.

[0003] A patent application with application number "202123295630.0" and titled "A High-Efficiency Microwave Baking Pan" discloses the following technical solution: the pan body is made of silicone, the microwave absorbing material layer is a solid gel-like substance, and the bottom plate is made of metal; the bottom plate is flat, with its edges curving upwards and embedded in the connecting part of the pan body; a hot-curing adhesive is applied between the bottom plate and the microwave absorbing material layer to cover the bottom of the baking pan. The microwave absorbing material layer absorbs electromagnetic waves and converts them into heat energy, cooking the food inside the pan. Because the heat is dissipated upwards from the bottom plate of the pan body, the food is grilled or roasted.

[0004] Based on the above technical solutions, applying a layer of microwave-absorbing material to the metal base plate can achieve the effect of heating the food inside. Therefore, an innovative solution is explored: designing a heater based on microwave-absorbing material. Discarded aluminum cans can be placed inside the heater, allowing them to be safely placed in a microwave oven. The microwave-absorbing material layer absorbs electromagnetic waves and converts them into heat energy, cooking the food inside the can and transforming it into a convenient cooking container. Utility Model Content

[0005] The purpose of this invention is to provide a metal container heating kit suitable for microwave heating, aiming to solve the technical problem that waste aluminum cans (or metal containers) cannot be directly used for microwave heating in the prior art, resulting in low recycling rate.

[0006] To achieve the above objectives, this utility model provides a metal container heating kit suitable for microwave heating, used to heat food inside a cylindrical metal container that opens at the top and closes at the bottom. The metal container has a concave lower section forming a recessed portion, and arc-shaped support feet are formed around the perimeter of the recessed portion. The wave-absorbing layer has a cylindrical structure that is open at the top and closed at the bottom. The metal container is inserted into the wave-absorbing layer from top to bottom. The inner sidewall of the wave-absorbing layer tightly wraps the outer sidewall of the metal container. The bottom of the wave-absorbing layer is provided with a protrusion that matches the recessed part. The periphery of the protrusion is also provided with a groove that matches the arc-shaped support foot. A silicone sleeve tightly wraps around the outer wall and bottom of the absorbing layer.

[0007] Furthermore, both the protrusion and the silicone sleeve have heat-conducting holes running vertically through the shaft.

[0008] Furthermore, the top edge of the silicone sleeve is provided with vertical anti-slip stripes arranged in a ring.

[0009] Furthermore, the top edge of the silicone sleeve is also provided with an outward-facing flange.

[0010] Furthermore, a cross-shaped support portion is provided below the protrusion, and an annular support portion connected to the cross-shaped support portion is provided with its central end as the center.

[0011] Furthermore, the top of the metal container has a smooth edge.

[0012] The above-mentioned technical solutions of the metal container heating kit suitable for microwave heating provided in this embodiment of the utility model have at least one of the following technical effects: This patented metal container heating kit achieves safe and efficient heating of metal containers in a microwave oven through the synergistic design of an absorbing layer and a silicone sleeve. The inner wall of the absorbing layer tightly wraps around the outer wall of the metal container, and the protrusions at the bottom of the absorbing layer precisely match the recesses at the bottom of the metal container, ensuring close contact to optimize heat conduction. The outer silicone sleeve both secures the absorbing layer and provides cooling. In operation, uncooked food is first placed into the metal container through the top opening, then the metal container is fitted into the absorbing layer and placed in the microwave oven. The absorbing layer converts microwaves into heat energy, which is transferred to the metal container. The high thermal conductivity of the metal ensures even heating of the food until it is cooked. This design overcomes the traditional limitation that metal containers cannot be microwaved, making it particularly suitable for repurposing discarded aluminum cans. It expands microwave cooking scenarios and achieves resource recycling. The entire structure is simple and reliable, with heating performance approaching that of conventional microwave containers, demonstrating significant practical value. Attached Figure Description

[0015] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings 1-3, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figure 1-3 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0016] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0019] The microwave absorbing layer 200 described in this patent is composed of microwave absorbing material, which is a functional material capable of absorbing and dissipating electromagnetic wave energy and possesses special electromagnetic properties in the microwave frequency band. Its core principle is to convert electromagnetic energy into heat energy through the dielectric and magnetic loss mechanisms of the material. This microwave absorbing material is existing technology and can include ferrite, carbon-based materials, conductive polymers, MXene, etc.

[0020] When microwave absorbing materials come into contact with a metal container, a special composite structure is formed. The main mechanisms of this structure include: 1. Interface polarization effect: A strongly polarized region forms at the interface between the absorbing material and the metal, enhancing the absorption of microwave energy. 2. Multiple reflection mechanism: Microwaves undergo multiple reflections between the absorbing material and the metal surface, extending the propagation path and increasing absorption efficiency. 3. Energy distribution regulation: The absorbing material can regulate the distribution of microwave energy around the container, preventing localized overheating. 4. A properly designed microwave absorbing material / metal composite structure can achieve microwave absorption efficiencies exceeding 90%, far higher than that of a single material.

[0021] Therefore, when microwave-absorbing materials are combined with metal containers, two major problems with metal in microwave ovens can be effectively solved: 1. Shielding effect: Metal strongly reflects microwaves, preventing energy from entering the container. Microwave-absorbing materials effectively absorb microwave energy, reducing reflection and allowing food inside the container to be heated evenly. 2. Arc discharge: Unevenness on the metal surface can lead to charge concentration and arc discharge. Microwave-absorbing materials can mitigate this charge accumulation and reduce the risk of arcing.

[0022] In one embodiment of this utility model, a metal container heating kit suitable for microwave heating is provided for heating food inside a cylindrical metal container 100 that opens at the top and closes at the bottom. The metal container 100 has a recessed portion 110 formed inwards at the bottom, and arc-shaped support feet 120 are formed around the recessed portion 110. The absorbing layer 200 has a cylindrical structure that is open at the top and closed at the bottom. The metal container 100 is inserted into the absorbing layer 200 from top to bottom. The inner sidewall of the absorbing layer 200 tightly wraps the outer sidewall of the metal container 100. The bottom of the absorbing layer 200 is provided with a protrusion 210 that matches the recess 110. The periphery of the protrusion 210 is also provided with a lower groove 220 that matches the arc-shaped support foot 120. The silicone sleeve 300 tightly wraps around the outer wall and bottom of the absorbing layer 200.

[0023] Specifically, the metal container 100 can be a container with a metal outer layer, such as an aluminum can. Taking an aluminum can as an example, the inner wall of the microwave-absorbing layer 200 tightly wraps around the outer wall of the metal container 100. The protrusion 210 at the bottom of the microwave-absorbing layer 200 precisely matches the concave bottom of the metal container 100, ensuring close contact to optimize heat conduction. The outer silicone sleeve 300 has a high temperature resistance between 200 and 300 degrees Celsius, both fixing the microwave-absorbing layer 200 and providing a safe and explosion-proof effect. During operation, uncooked food is first placed into the metal container 100 through the top opening. Then, the metal container 100 is placed inside the microwave-absorbing layer 200, and the entire container is placed in the microwave oven. Microwaves pass through the silicone sleeve 300 to reach the microwave-absorbing layer 200, where the microwave-absorbing layer 200 converts the microwaves into heat energy and transfers it to the metal container 100. The high thermal conductivity of the metal ensures uniform heating of the food to cook it thoroughly. This design breaks through the traditional limitation that metal containers cannot be microwaved, making it particularly suitable for repurposing discarded aluminum cans. It expands microwave cooking scenarios and achieves resource recycling. The entire structure is simple and reliable, and its heating effect is close to that of conventional microwave containers, demonstrating significant practical value.

[0024] Furthermore, both the protrusion 210 and the silicone sleeve 300 are provided with through-holes 230 in the same vertical direction. By providing through-holes 230 in the protrusion 210 of the absorbing layer 200 and the silicone sleeve 300, the hot air convection path is optimized, effectively preventing heat accumulation at the bottom, while promoting steam discharge and avoiding uneven heating of food due to local overheating.

[0025] Furthermore, the top edge of the silicone sleeve 300 is provided with vertical anti-slip stripes 310 arranged in a ring. The vertical anti-slip stripes 310 on the top edge of the silicone sleeve 300 increase the friction when holding the hand, prevent the kit from slipping due to steam condensation or oil stains, improve operational stability, and are suitable for picking up and putting down in high temperature or humid environments.

[0026] Furthermore, the top edge of the silicone sleeve 300 is provided with an outward flange 320, which further expands the force-bearing area of ​​the top of the silicone sleeve 300, and together with the anti-slip stripes, enhances the overall anti-slip effect.

[0027] Furthermore, a cross-shaped support portion 240 is provided below the protrusion 210, and an annular support portion 250 connected to the cross-shaped support portion 240 is provided with its central end as the center. The combined structure of the cross-shaped support portion 240 and the annular support portion 250 enhances the mechanical strength of the bottom of the absorbing layer 200.

[0028] Furthermore, the top of the metal container has a smooth edge to prevent sharp edges from causing tip discharge in a microwave environment, thus ensuring the safety and stability of the microwave heating process.

[0029] Production process: 1. Recycling and pretreatment of waste aluminum cans (metal containers): Collect waste aluminum cans and clean, disinfect and treat their surfaces.

[0030] 2. Preparation of microwave absorbing materials: Prepare microwave absorbing materials according to the selected formula, which can be done by methods such as powder mixing, solution mixing or melt mixing.

[0031] 3. Cup sleeve molding: The microwave absorbing layer is molded into a cup sleeve shape through processes such as injection molding, compression molding, or coating.

[0032] 4. Surface treatment: The surface of the cup sleeve is specially treated, such as by adding a layer of silicone sleeve, to improve the fit and stability with the can.

[0033] 5. Quality Inspection: Conduct comprehensive quality inspections on the finished products, including microwave absorption performance testing, heat resistance testing, and safety performance testing.

[0034] 6. Packaging and Warehousing: Pack the qualified products and put them into the warehouse for sale.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
