[0041] Reference Figures 1 to 11A heat reflection module for an electric oven, the electric oven includes an oven body 100 and a heating component 300, the oven body 100 is provided with a baking cavity 110, the inner wall of the baking cavity 110 is provided with an installation step 111, the heat reflection module includes a reflection plate 830, a connecting plate 820, a mounting plate 810 and an exciter 840: the reflection plate 830 is V-shaped and has a plurality of reflection surfaces coated with a reflection coating; the connecting plate 820 and the reflection plate 830 are connected by the connecting plate 820, and the connecting plate 820 is provided with a plurality of rectangular openings 821, adjacent The two reflecting plates 830 and the connecting plate 820 therebetween form a reflecting unit, which is used to correspond to the heating unit of the electric oven; the reflecting plate 830 at the front end of the mounting plate 810 and the reflecting plate 830 at the end are both connected to the connecting plate 820 for extension, the mounting plate 810 is connected to the connecting plate 820 for extension, and the mounting plate 810 is used to be mounted on the installation step 111; the vibrator 840 is arranged in the oven body 100, the vibrator 840 is connected to the mounting plate 810 for transmission, and the vibrator 840 is used to vibrate away the oil attached to the reflecting plate 830.

[0042] The reflective plate 830, connecting plate 820, mounting plate 810 and exciter 840 constitute a heat reflection module of the electric oven. Heat reflection is achieved through the heat reflection module. When baking food, heat reflection can not only save energy and reduce consumption, but also re-bake the food to make the food taste better. In addition, the heat reflection module reduces the distance from the heating component 300, so that the splashing amplitude of the oil for baking food is reduced when dripping, avoiding the oil from splashing everywhere. The reflective unit composed of the V-shaped reflective plate 830 and the connecting plate 820 can not only concentrate the heat, but also guide and dredge the oil, and also play a role in receiving the oil. The exciter 840 can vibrate and remove the oil attached to the reflective plate 830, so that the reflective surface of the reflective plate 830 can maintain the heat reflection effect.

[0043] It should be noted that a push switch 113 is provided on the installation step 111. The push switch 113 is slidably connected to the oven body 100 through an elastic member 114. The push switch 113 is connected to the circuit of the vibrator 840. The elastic member 114 drives the push switch 113 to move upward. The push switch 113 supports the mounting plate 810, and the vibrating end of the vibrator 840 abuts against the mounting plate 810. It should be understood that the reflective plate 830, the connecting plate 820 and the mounting plate 810 are integrally formed, and the reflective plate 830, the connecting plate 820 and the mounting plate 810 are made of copper or aluminum. Two rectangular openings 821 are opened on the connecting plate 820, and the rectangular opening 821 is opened in the middle of the connecting plate 820. The mounting plate 810 is provided with a hook portion 811, and the hook portion 811 is mounted on the installation step 111. The roughness of the reflecting surface is set to Ra1.6-Ra3.2, and the reflective coating includes aluminum foil coating, ceramic coating or stainless steel coating. It can be understood that the vibrator 840 is a common vibrator, similar to the cylindrical vibrator on an electric toothbrush, which is mainly used to generate vibration and transmit the vibration to the reflective plate 830, so that the reflective plate 830 can also vibrate, thereby shaking off the oil on the reflective plate 830. Oil will accumulate on the reflective plate 830 to a greater or lesser extent, and pure oil will not adhere too much to the reflective plate 830. Because when baking food, a mixture of food residues and oil is most likely to remain on the reflective plate 830, which will form scabs or become sticky over time, making it very difficult to clean later and easy to hide bacteria. Therefore, vibration is used to control the amplitude to achieve the effect of vibrating away oil residues. The control is to use a general PLC to control the speed of the power motor of the vibrator. This is a conventional control method.

[0044] In some embodiments, a guide slope 822 is disposed at the edge of the rectangular opening 821 . It is understandable that the guide slope 822 is disposed at the upper edge of the rectangular opening.

[0045] In some embodiments, an insulating block is connected under the reflective plate 830, and an inductor is disposed on or inside the insulating block. When the inductor is energized, the coil generates eddy currents in the reflective plate 830, thereby generating heat. The inductor, in conjunction with the vibrator 840, can better remove oil residues, and the heat generated by the reflective plate 830 can further promote the heating below the heating component 300, thereby ensuring the thermal stability and intensity of the lower part of the food.

Due to the presence of the elastic member 114, the heat reflection module is supported and lifted up by the push switch 113, and at this time, the vibrating end of the exciter 840 abuts against the mounting plate 810. When the oil accumulated on the reflecting plate 830 exceeds a predetermined weight, the push switch 113 is pressed and turned on, so that the exciter 840 vibrates, thereby removing the oil on the reflecting plate 830;

[0048] S2, one end of the oven body 100 on which the heating component 300 is provided is hinged to the oven body 100, and the heating component 300 is swung down so that the other end of the heating component 300 overlaps the second step 112, so that the heating component 300 is placed above the reflecting plate 830, and the heating unit on the heating component 300 is arranged corresponding to the reflecting unit.
