Abstract

The invention discloses a microwave oven door structure for preventing microwaves from leaking. The microwave oven door structure comprises an oven door and an oven body. The oven door is installed in the front side of the oven body. A seal layer is arranged on the portion, making contact with the oven body, on the oven door. The portion, provided with the seal layer, of the surface of the oven door is a saw tooth concave-convex face. Microwave absorption layers are arranged on the portion, provided with the seal layer, of the surface of the oven door and the seal layer correspondingly. Each microwave absorption layer comprises, by weight, 15-40 parts of ceramic powder, 5-12 parts of stainless steel fiber and 50-80 parts of a resin tackifier. The microwave absorption layers are arranged on the seal layer and the oven door and can effectively absorb and attenuate the microwaves, the microwaves are prevented from leaking, and harm caused by microwave leakage to human bodies is avoided.

Description

technical field [0001] The invention relates to the field of microwave ovens, in particular to a microwave oven door structure for preventing microwave leakage. Background technique [0002] A microwave oven is a modern cooking stove that uses microwaves to heat food. A microwave oven is composed of a power supply, a magnetron, a control circuit, and a cooking cavity. The power supply provides a high voltage of about 4000 volts to the magnetron. Under the excitation of the power supply, the magnetron continuously generates microwaves, and then couples into the cooking cavity through the waveguide system. Near the entrance of the cooking cavity, there is a rotatable stirrer, because the stirrer is a fan-shaped metal, which can reflect the microwave in all directions after rotating, so it can evenly distribute the microwave energy in the cooking cavity, thus Reheat food. [0003] However, there is a common problem of microwave leakage in microwave ovens at present. When the...
