Oven and controlling method thereof

Abstract

The invention discloses an oven, which comprises a control panel, an oven chamber and a heater. The oven is characterized by comprising an infrared temperature sensor which is arranged outside the oven chamber and can sense temperature of food in the oven chamber, a humidity sensor which is fixed outside the oven chamber and communicated with the oven chamber, and a probe type sensor arranged in the oven chamber, wherein the infrared temperature sensor, the humidity sensor and the probe type sensor are in controllable connection with a control circuit. The invention also discloses a controlling method of the oven. According to the method, automation of roasting is realized by utilizing programmed control roasting, users are liberated by greatly reducing the roasting difficulty, and the oven door is prevented from being frequently opened, energy loss is effectively reduced, the phenomena, such as the surface of a roasted food is burnt but the center of the roasted food is not sufficiently cooked and the like, can be avoided by utilizing cooperation of the sensors, intermittent roasting and switching of different time segments and different fire powers can be effectively realized, the internal temperature of food is detected in real time, and roasting is stopped instantly after the inside of the food is cooked, so that energy consumption is reduced.

Description

technical field [0001] The invention relates to an oven, in particular to an intelligent oven with multiple sensors capable of automatic cooking. Background technique [0002] A microwave oven is a device that generates microwaves from an electric current and irradiates the microwaves to the surface of the object to be heated in the cavity to heat the object. As everyone knows, microwave oven is a kind of modern cooking stove that heats food with microwave. The microwave it uses is a kind of electromagnetic wave. The energy of this electromagnetic wave is not only much greater than that of ordinary radio waves, but also has special characteristics. When the microwave hits metal, it will reflect, and the metal has no way to absorb or conduct it; microwave can pass through insulation such as glass, ceramics, and plastics. Materials, but will not consume energy; and food containing water, not only can not pass through the microwave, but its energy will be absorbed. Based on ...

AI Technical Summary

Problems solved by technology

[0005] The oven in the prior art does not lack intelligence, and customers need to check the grilling status repeatedly, which is easy to burn or not cooked. Since there is no feedback information from the sensor, the grilling work is a fixed time program based on experience and cannot be carried out according to the amount and state of the food. Adjust in time; especially for baking cakes or bread, it is necessary to check the grilling status repeatedly. Frequent opening of the door increases the heat loss and takes up the user's time. practicality
