A kind of oven and working method thereof

Abstract

The invention relates to an oven and a working method thereof. The oven comprises an oven body, a cooking chamber arranged in the oven body, an upper heating pipe which is arranged in the oven body and located over the cooking chamber, a middle heating pipe which is arranged in the oven body and located in the middle of the cooking chamber, a temperature detection device for measuring the temperature inside the cooking chamber, a fan which is arranged on the back of the oven body and can blow rotational wind into the cooking chamber and an oven control unit which is connected with the temperature detection device, the upper heating pipe, the middle heating pipe and the fan and used for controlling work of the upper heating pipe and the middle heating pipe. The oven is characterized in that the temperature detection device comprises a first temperature sensor located in the middle of the upper portion of the cooking chamber and a second temperature sensor located on the side of the upper portion of the cooking chamber. Compared with the prior art, the oven has the advantages that temperature deviation of the upper surfaces of food can be better corrected to enable same-layer temperature fields of the food to keep uniform, and therefore the requirement that the oven is more precisely controlled to bake the different food can be met.

Description

technical field [0001] The invention relates to an oven and its working method. Background technique [0002] With the development of import and export trade, people are more and more fond of Western cooking. Diet methods such as homemade DIY pastries and baked meat are sought after by people. Therefore, the oven has also received high attention as a new cooking tool. [0003] As a closed appliance for baking food, the oven has a large internal volume, and a temperature sensor is generally used to measure its internal temperature; however, due to its small size and limited installation methods, the internal temperature sensor of the oven can only measure the inner wall of the oven. The temperature of a certain point around, take the temperature of this measurement point as the overall oven internal temperature or regard this temperature as the temperature of the food being cooked, and then carry out subsequent heating control according to this temperature, which will cause...

AI Technical Summary

Problems solved by technology

Due to the one-way rotation of the general fan, it is easy to cause different heat transfer conditions on the left and right sides of the same layer, that is, the temperature on the left and right sides is uneven.

Due to the above reasons, it is unscientific to use a single temperature probe as the basis for the temperature of the entire oven, and it will easily lead to uneven color of food during baking
