Electric oven and control method thereof

Abstract

The invention relates to an electric oven and a control method thereof. The electric oven comprises an inner container with a cooking chamber, an upper electric heating tube arranged at the top of the inner container, and a control panel connected with the upper electric heating tube and capable of controlling working of the upper electric heating tube, and is characterized in that a reflective plate capable of reflecting heat radiation generated by the upper electric heating tube back into the inner container is mounted inside the inner container and above the upper electric heating tube and the reflective plate can cover the whole upper electric heating tube. Compared with the prior art, the electric oven has the advantages as follows: through mounting of the reflective plate capable of reflecting the heat radiation generated by the upper electric heating tube back into the inner container above the upper electric heating tube, the heat energy utilization efficiency of the upper heating tube can be greatly improved.

Description

technical field [0001] The invention relates to an electric oven and a control method thereof. Background technique [0002] In the existing electric oven liner, an upper heating tube and a lower heating tube are generally provided, the upper heating tube is located at the top of the oven liner, and the lower heating tube is located at the bottom of the oven liner. During the use of the oven, after the air is heated by the heating tube, only natural convection can occur without external power. Therefore, the heat exchange method of the upper heating tube and the lower heating tube is natural convection, and the characteristics of natural convection must be It will cause the hot air to rise, and the air outlet of the general oven is also located on the top of the oven liner, so the heat generated by the upper heating tube will be directly taken out of the oven by the rising hot air, that is, the heat energy utilization of the upper heating tube is low. Although adding a hot ...

Problems solved by technology

During the use of the oven, after the air is heated by the heating tube, only natural convection can occur without external power. Therefore, the heat exchange mode of the upper heating tube and the lower heating tube is natural convection, and the characteristics of natural convection must be It will cause the hot air to rise, and the air outlet of the general oven is also located on the top of the oven liner, so the heat generated by the upper heating tube will be directly taken out of the oven by the rising hot air, that is, the heat energy utilization of the upper heating tube is low.

Although adding a hot air fan on the top of the oven liner can improve the heat exchange efficiency, but this must be at the expense of the baking space
