Embodiment

[0009] The inner side of the door and window plate of the microwave oven of the present invention is coated with temperature-sensitive ink silk screen printing, and the pattern that will appear on the door and window plate when the temperature of the door and window plate rises is printed on the ink silk screen. In this embodiment, the temperature-sensitive ink screen printing is provided with three temperature nodes, which are normal temperature, 40 degrees, and 60 degrees. When the temperature rise of the door and window panels reaches a certain level, patterns will appear on the door and window panels.

[0010] The working principle of the present invention is: at room temperature, the temperature-sensitive ink screen printing does not change, so there is no relevant pattern on the door and window panels; It is displayed; when the temperature continues to rise to a certain set value, the pattern is fully displayed, reminding the user that the temperature of the door and win...

Abstract

The invention relates to a door and window plate of a microwave oven, in particular to a door and window plate of a heat discoloration microwave oven. The door and window plate is coated with temperature sensing ink silk screen printing at the inner side, and the ink silk screen printing is printed with patterns which can emerge on the door and window plate when the temperature of the door and window plate rises. The temperature sensing ink silk screen printing is provided with a plurality of temperature nodes. As the inner side of door and window plate is coated with the temperature sensing ink silk screen printing, the patterns can emerge on the door and window plate when the temperature of the door and window plate rises. The temperature of the door and window plate can be showed by the patterns, so that the aim of reminding the user can be achieved. Meanwhile, the display of the patterns has the function of being beautiful.

Description

Technical field: [0001] The invention relates to a microwave oven door and window panel, in particular to a temperature-sensitive and color-changing microwave oven door and window panel, which belongs to the modification technology of the microwave oven door and window panel. Background technique: [0002] Existing microwave oven door and window panels are generally made of glass, which play the role of heat insulation and light transmission. Consumers can see the heating of food in the oven cavity through the door and window panels. However, in the actual use process, since the temperature of the door and window panels will increase, the user will accidentally touch the door and window panels, which will cause certain injuries and endanger the user's safety. Utility model content: [0003] The purpose of the present invention is to consider the above problems and provide a temperature-sensitive color-changing microwave oven door and window panel that can change its patter...
