Oven and hot air control device thereof

Abstract

The invention discloses an oven and a hot air control device thereof; the hot air control device comprises a fan capable of rotating forwards and backwards, heating pipes, temperature sensors, and a controller; and when the fan rotates forwards, the air outlet amount of the right half part of the fan is larger than that of the left half part of the fan; the heating pipes are uniformly arranged in the circumferential direction of the fan; the temperature sensors are arranged in the oven and comprise a left side temperature sensor located on the left side of the fan and a right side temperature sensor located on the right side of the fan; a controller is used for obtaining the temperatures measured by the left side temperature sensor and the rear side temperature sensor and controlling the working state of the fan to change, and when the temperature value detected by the left side temperature sensor is larger than the temperature value detected by the right side temperature sensor, the controller controls the fan to rotate forwards; when the temperature value detected by the left side temperature sensor is smaller than the temperature value detected by the right side temperature sensor, the controller controls the fan to rotate reversely. The purpose of controlling the temperature is achieved through the control process, and uniform distribution of heat is achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an oven and a hot air control device thereof. Background technique [0002] An oven is a household appliance that uses the radiant heat from an electric heating element to bake food. When working, the electric heating element set in the oven will be fixed at a specific position in the oven box. In order to ensure the consistency of the temperature everywhere in the oven, the heat generated by the electric heating element needs to be processed, that is, the heat needs to be dispersed to achieve a uniform distribution. In view of this, a fan structure needs to be provided in the oven. [0003] However, when the oven uses the back hot air mode to bake food, it completely relies on the hot air brought by the back fan to heat the food and maintain the temperature in the oven. The farther the heating tube is, the lower the temperature will be, which will cause the temper...

[0003] However, when the oven uses the back hot air mode to bake food, it relies entirely on the hot air brought by the back fan to heat the food and maintain the temperature in the oven. The farther the heating tube is, the lower the temperature will be, which will cause a certain difference in the temperature of different positions in the oven, which will affect the baking effect
