Description

A microwave heating element Technical Field

[0001] This invention relates to the field of cookware technology, specifically to a microwave heating element. Background Technology

[0002] Currently, microwave ovens, besides heating food in microwave-permeable containers, can also be used with cooking utensils such as microwave baking pans and microwave pots to perform grilling-like processes on food. Their working principle involves the microwave-absorbing material on the cooking utensils absorbing microwave energy and generating heat, which is then transferred to the metal container of the cooking utensils, thereby transferring heat to the food. Microwave pots are essentially a single, integral structure; that is, the pot containing the food and the microwave-absorbing material are inseparable. Chinese invention patent application CN113301833A discloses a microwave oven cooking utensil that forms a heating space S between an upper and lower microwave heating element, simultaneously heating the cooking material M from both above and below. The upper and lower microwave heating elements are respectively formed by a heating element accompanied by ferrite and a foamed molding body. This type of integral microwave oven cooking utensil has limitations when cooking different quantities of food. To cook different amounts of food, households need to have microwave pots of different capacities. Furthermore, because the microwave heating layer is fixedly attached to the pot or plate and cannot be disassembled, it causes inconvenience in cleaning and maintenance. Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a split-type microwave heater.

[0003] On the other hand, current microwave baking pans and microwave pots are only used for food cooking, and their application range is relatively narrow. Summary of the Invention

[0004] The purpose of this invention is to provide a microwave heating element that can provide a heat source for food cooking and can also be used as a hot cutting board, defrosting board, etc., with a wide range of applications, thus overcoming the shortcomings of the prior art.

[0005] The technical solution of the present invention is: a microwave heating body, comprising a microwave absorbing layer and an encapsulation body, wherein the encapsulation body completely or partially encapsulates the microwave absorbing layer; the microwave absorbing layer is used in a microwave oven to absorb microwaves and convert them into heat.

[0006] A carrier is placed on a microwave heating element, wherein the microwave heating element and the carrier are independent of each other.

[0007] The carrier is a cookware, and the microwave heating element is used to heat and cook food. The microwave heating element has a cookware placement surface, and the wrapping body completely covers the microwave absorbing layer. The cookware placement surface is on the upper surface of the wrapping body.

[0008] The package has an opening, which is located on the upper surface of the package. The microwave absorbing layer is placed inside the opening and is partially wrapped by the package.

[0009] The package is integrally provided with ribs, which form the base structure of the microwave heating element.

[0010] The ribs are a number of concentric rings.

[0011] The adjacent rings are spaced equally apart.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows:

[0013] 1. This invention, by incorporating a microwave-absorbing layer within the heating adhesive's encapsulation, allows the microwave heating element to be heated within a microwave oven. Therefore, it can be used as a heat source for food cooking, and after heating, it can be removed from the microwave oven and used as a hot cutting board, or for defrosting frozen products. Furthermore, the microwave-absorbing layer and the encapsulation can be an inseparable integral structure or a detachable and replaceable split structure, offering a variety of structural options and greater convenience.

[0014] 2. The heating adhesive of the present invention can be designed with partial or full wrapping.

[0015] 3. When the microwave heating element is used as a food cooking utensil, because the heating element is separate from the container, one microwave heating element can be paired with metal cookware of different sizes, thus achieving more flexible applications. Compared with existing integrated microwave cookware, the microwave absorption layer transfers heat more evenly, effectively improving microwave heating efficiency. Attached Figure Description

[0019] The numbers in the attached diagram represent the following: microwave heating element 1, tall cookware 2, flat cookware 3, microwave absorption layer 11, wrapping body 12, ribs 121, cookware placement surface 101, pot body 31, pot lid 32, and pot handle 33. Detailed Implementation

[0020] Example 1

[0021] A microwave heating element includes a microwave absorbing layer 11 and an encapsulation body 12, wherein the encapsulation body 12 completely or partially encapsulates the microwave absorbing layer 11; the microwave absorbing layer 11 is used in a microwave oven to absorb microwaves and convert them into heat.

[0022] A container can be placed on the microwave heating element for heating food or other items on it. It can also be used directly as a heat source. When a container is placed on it, the microwave heating element and the container are independent of each other.

[0023] Example 2

[0024] Referring to Figure 1, a container is placed on the microwave heating element. The microwave heating element is used to heat and cook the food inside the container. In this embodiment, the container is a flat-bottomed tall pan, and the microwave heating element is used in conjunction with the flat-bottomed tall pan. The microwave heating element 1 and the pan 2 are independent of each other. The pan 2 is covered with a lid. The microwave heating element 1 includes a microwave absorbing layer 11 and a wrapping body 12, which are integral structures. The microwave heating element 1 has a pan placement surface 101. The wrapping body 12 completely or partially wraps the microwave absorbing layer 11. When the microwave absorbing layer is completely wrapped, the pan placement surface 101 is on the upper surface of the wrapping body. When the microwave absorbing layer is partially wrapped, the pan placement surface 101 is on the upper surface of the microwave absorbing layer.

[0025] In use, the microwave heating element is placed at the bottom of a flat-bottomed tall cookware and then placed inside a microwave oven. When the microwave heating element is heated inside the microwave oven, because the casing 12 is made of a microwave-permeable material, the microwaves penetrate the casing 12, and the microwave absorption layer 11 absorbs the microwaves, generating heat. This heat is then conducted through the cookware placement surface 101 to the tall cookware 2. The food being cooked is heated inside the cookware and completes its cooking process with continued heating.

[0026] Example 3

[0027] In this embodiment, the present invention is used in conjunction with a flat-bottomed, short cookware. Referring to Figures 2-3, to accommodate the cooking needs of different ingredients, the tall cookware 2 is replaced with a short cookware 3, which is placed on the microwave heating element 1 in contact with the cookware placement surface 101. When the microwave oven is operating, microwaves penetrate the enclosure 12 and are absorbed by the microwave absorption layer 11, generating heat. This heat is conducted to the flat cookware 3 through the cookware placement surface 101, and the food being cooked is heated inside the cookware and cooked through the continuous heating process. The enclosure 12 of the cookware is integrally provided with ribs 121, which form the base structure of the microwave heating element. The ribs are several concentric rings, with adjacent rings spaced equally apart. The cookware 3 consists of a pot body 31 and a lid 32. The microwave heating element 1 includes a microwave absorption layer 11 and a wrapping body 12. During microwave heating, the microwave heating element 11 absorbs microwave energy and converts it into heat, which is then conducted to the pot body 31. During use, the lid 32 is placed on top to prevent heat loss and to avoid microwaves directly penetrating the food. The lid has a non-heat-conducting handle 33 for user convenience. Ribs 121 are located at the bottom of the wrapping body 12. These ribs, acting as support legs, have a concentric circular structure with equal spacing between them. This structure increases the heating area, improves microwave absorption efficiency, and ensures that the food inside the pot is heated evenly, improving the taste of the cooked food.

[0028] In the accompanying drawings, the package 12 completely encloses the microwave absorbing layer 11. As an improvement, the package 12 may partially enclose the microwave absorbing layer 11. For example, an opening may be provided in the package 12, opening onto the upper surface of the package 12, with the microwave absorbing layer placed inside the opening. This opening may protrude from, be below, or be flush with the upper surface of the package 12. Alternatively, the package 12 and the microwave absorbing layer 11 may be fixed as a single unit, or the package 12 may only serve as a container for the microwave absorbing layer 11, which can be removed and replaced from the package 12.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
