Abstract

A microwave-oven cooking pot, comprising a cover (1) and a body (2). A microwave absorption layer (3) coats the bottom wall of the body (2). Support legs (5) are provided under the body (2) and are mounted on the body (2). The support legs (5) are made of a material different from that of the microwave absorption layer (3), and the support legs (5) are attached onto the microwave absorption layer (3). The support legs (5) being made of a material that is different from that of the microwave absorption layer (3) can prevent heat from concentrating at the support legs (5), thereby making food be heated more evenly, and thus achieving the optimal cooking effect. The parts of support leg portions (7) that are not provided with the microwave absorption layer can also separate the microwave absorption layer (3) at the bottom of the body (2) from a placement surface, thereby preventing a microwave absorption material from adhering to the surface in contact with the bottom of the pot, and thus reducing the difficulty in terms of cleaning the pot after use.

Description

A microwave cooking pot Technical Field

[0001] This utility model relates to the field of microwave oven cooking equipment technology, and in particular to a microwave oven cooking pot. Background Technology

[0002] In existing technology, microwave ovens with a microwave-absorbing layer on the bottom wall are available. Typically, this layer is integrally formed with downward-protruding support feet. However, these support feet made of microwave-absorbing material have two drawbacks: First, under microwave radiation, the support feet absorb electromagnetic waves and convert them into heat. This heat concentrates on the four feet, leading to uneven heating of the bottom of the oven and consequently uneven cooking of the food, affecting the cooking results. Second, when the support feet come into contact with other flat surfaces, the microwave-absorbing material tends to adhere to those surfaces, increasing the difficulty of cleaning the microwave oven after use.

[0003] Utility Model Content

[0004] The purpose of this utility model is to provide a microwave oven cooking pot with an independently set support foot at the bottom, changing the current situation where the support foot is made of microwave absorbing material, so as to overcome the shortcomings of the above-mentioned prior art.

[0005] The technical solution of this utility model is: to provide a microwave oven cooking pot, including a lid and a pot body, wherein a microwave absorbing layer is applied to the bottom wall of the pot body, and a support foot is provided at the bottom of the pot body, wherein the material of the support foot is different from that of the microwave absorbing layer.

[0006] Furthermore, the support feet are bonded to the microwave absorbing layer by adhesive or vulcanization.

[0007] Furthermore, the support foot includes an upper boss and a foot portion. The diameter of the upper boss is larger than the diameter of the foot portion. The upper boss is embedded in the microwave absorbing layer, and the foot portion protrudes outward from the microwave absorbing layer.

[0008] Furthermore, the upper end of the support foot is wrapped with a microwave absorbing layer, which is stepped or platform-shaped.

[0009] This invention offers the following advantages: Firstly, the support legs of a microwave-safe cooking pot are made of a different material than the microwave-absorbing layer on the bottom wall of the pot. This prevents heat from concentrating on the support legs, allowing for more even heating of the food and achieving optimal cooking results. Secondly, the absence of a microwave-absorbing layer on the support legs also separates the microwave-absorbing layer from the surface on which the pot is placed, preventing the microwave-absorbing material from adhering to the surface in contact with the pot bottom and reducing the difficulty of cleaning after use.

[0014] 1. Lid, 2. Pot body, 3. Microwave absorption layer, 4. Boss, 5. Support foot, 6. Grip, 7. Support foot. Detailed Implementation

[0015] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0016] Example 1

[0017] Referring to Figures 1-3, a microwave cooking pot includes a pot body 2 and a lid 1. The lid 1 has an outwardly extending rim, which is wrapped with a silicone ring and has a gripping part 6. The pot body 2 has a metal pot-shaped body with an outwardly extending rim at the opening edge. A microwave absorbing layer 3 is provided on the outer surface of the bottom wall of the pot body. Under the action of microwaves, the microwave absorbing layer absorbs the electromagnetic waves emitted by the microwave oven and converts them into heat, thereby providing a heat source for cooking.

[0018] The bottom of the pot has four support feet 5, which are either frustum-shaped or inverted cone-shaped. The support feet 5 can be made of non-metallic materials such as silicone, plastic, or ceramic. The material of the support feet 5 differs from that of the microwave absorbing layer 3. Because it does not use microwave absorbing material, it avoids the heat energy from concentrating on the four feet, thus preventing localized overheating of the pot bottom. The support feet 5, made of non-absorbing material, ensure even heating of food, achieving optimal cooking results. The microwave absorbing layer 3 and the support feet 5 can be bonded together (see the first support foot structure in Figure 3). Adhesive is evenly applied to the contact surface between the support feet 5 and the microwave absorbing layer 3, and pressure is applied to prevent air bubbles, ensuring a tight bond between the support feet 5 and the microwave absorbing layer 3. Alternatively, the microwave absorbing layer 3 and the support feet 5 can be thermoformed. The support feet, pot body, and microwave absorbing material are placed in a mold, which is then heated and pressurized in an equipment for a period of time before being removed and formed.

[0019] Referring to the second support leg structure shown in Figure 3, as an improvement, the support leg 5 consists of an upper boss 4 and a lower support leg 7. The microwave absorbing layer 3 on the bottom wall of the pot wraps around the upper bosses 4 of the four support legs 5, thus providing good support for the support legs 5 and preventing them from detaching from the microwave absorbing layer 3. The microwave absorbing layer 3 and the support legs 5 are formed by hot pressing.

[0020] Referring to the third support leg structure shown in Figure 3, the microwave absorption layer is stepped, and the pot body, microwave absorption layer, and support leg can also be formed by hot pressing.

[0021] Referring to the fourth support leg structure shown in Figure 3, the microwave absorption layer is platform-shaped, and the pot body, microwave absorption layer, and support leg can also be formed by hot pressing.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
