Oven and heating control method thereof

Abstract

The invention provides an oven and a heating control method thereof and relates to the technical field of kitchen appliances. The oven comprises a housing and a lining arranged in the same; a controlboard is arranged between the housing and the lining; the top, bottom, left and right of the lining are provided with an upper heating device, a lower heating device, a left heating device and a rightheating device respectively which are connected with the control board; the top, bottom, left and right of the wall of the lining are provided with an upper ranging device, a lower ranging device, aleft ranging device and a right ranging device which are connected with the control board; the ranging devices in the various directions are used for measuring distances between the wall of the liningand food under baking; the control board is used for adjusting heating power of the corresponding heating device according to the distances in the various distances. The heating power is adjusted according to the differences of the distances from the heating devices to the food under baking, heat for the food under baking is more uniform, the surface of the food can be colored highly evenly, andcolor differences are small.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an oven and a heating control method thereof. Background technique [0002] At present, in the oven, in order to realize the uniform heating of the food, the heating elements on the top surface, the bottom surface, the left side and the right side are used for heating, and the circulating hot air is set on the rear side to stir and heat the baking cavity, which improves the food quality to a certain extent. Uniformity of heating, but still not ideal in terms of uniformity of food browning. This is because the coloring of food is greatly affected by direct heat radiation, and when placing food in the oven, the placement position will vary greatly each time, and it cannot ensure accurate placement in the preset design. Therefore, the temperature of the place where the food to be baked is close to the heating element is continuously high, while the temperature of the pla...

Problems solved by technology

This is because the coloring of food is greatly affected by direct heat radiation, and when placing food in the oven, the placement position will vary greatly each time, and it cannot ensure accurate placement in the preset design. Therefore, the temperature of the place where the food to be baked is close to the heating element is continuously high, while the temperature of the place far away from the heating element is continuously low, which makes the color of the food to be baked appear huge difference
