Abstract

The invention discloses a microwave oven door seal cover arranged inside the microwave oven door. The seal cover comprises a central window corresponding to the oven door glass with an appearance of rectangular shape and a first flange. Therein, the first flange is continuously formed at periphery of the window, and a second flange spaced with the first flange is also equipped, being continuously formed at periphery of the first flange. Compared with conventional art, the invention adopts dual flange to isolating the oven door inner part, and can more effectively prevents penetration of moisture, foreign matter and so on. In addition, even if one flange generates deformation because of high temperature of the cooking cavity, another flange will isolate the oven door inner part, and consequently, structural reliability can be improved.

Example Embodiment

[0026] Hereinafter, the sealing cover of the microwave oven door provided by the present invention will be described in detail with reference to the accompanying drawings. It should be noted here that, in order to avoid repetition of description, the same parts as in the traditional technology are quoted with the same symbols below.

[0027] The present invention is an invention based on an ordinary microwave oven, and is applied to an ordinary microwave oven, because the structure of an ordinary microwave oven has been described above. Therefore, the description of the microwave oven is omitted here.

[0028] image 3 It is a schematic diagram of an embodiment of the microwave oven door sealing cover 244 provided by the present invention. Figure 4 After adopting the sealing cover 244, the exploded schematic diagram of the furnace door assembly.

[0029] The sealing cover 244 provided by the present invention has a rectangular appearance with a quadrangular mouth formed in the center. The opening 244c is a window corresponding to the oven door glass 142, through which the inside of the cooking cavity 20 can be observed. Hereinafter, the port is referred to as window 244c.

[0030] On the periphery of the window 244c, a first flange 244a is formed at a certain height. The first flange 244a is continuously formed around the window 244c. A protruding piece 244d is formed at the front end of the first flange 244a, and the protruding piece 244d can be inserted into the furnace door frame 143.

[0031] On the periphery of the first flange 244a, a second flange 244b is formed at a certain interval from the first flange 244a. The second flange 244b is continuously formed around the periphery of the first flange 244a, and its height is equivalent to the height of the first flange 244a.

[0032] The sealing cover 244 is made of plastic, synthetic rubber and other materials, and is formed by injection molding.

[0033] The microwave oven door sealing cover 244 provided by the present invention has the following functions.

[0034] As described above, the sealing cover 244 is assembled at the rear end of the oven door panel 141 and tightly coupled to the back of the oven door frame 143 to prevent moisture generated during the cooking process from penetrating into the oven door.

[0035] The present invention is characterized by forming a double flange on the sealing cover 244 to prevent the penetration of moisture.

[0036] That is, the second flange 244b formed on the outer periphery first prevents the penetration of moisture, and then the first flange 244a formed on the inner side prevents the penetration of moisture again.

[0037] In this way, a double isolation structure is adopted to improve the function of preventing moisture penetration.

[0038] In addition, the sealing cover 244 is made of plastic, synthetic rubber and other materials. Therefore, heat resistance is poor, and deformation is likely to occur. However, in the present invention, a double flange structure is adopted. Therefore, even if one of the double flanges is deformed, there is another flange that prevents the penetration of moisture. Thereby increasing the reliability.

[0039] The embodiment provided by the present invention is only an example for specifically expressing the technical idea of the present invention. Undoubtedly, within the scope of the basic technical idea of the present invention, there are still many ways to improve positions, shapes, materials, etc.
