Microwave oven capable of being heated to fixed temperature

Abstract

The invention discloses a microwave oven capable of being heated to a fixed temperature. The microwave oven comprises a shell, a heating space and a heating disc arranged in the shell, a furnace door for sealing the heating space, a controller for controlling the operation of the microwave oven, and a control panel arranged on the front surface of the shell. The microwave oven capable of being heated to the fixed temperature is characterized by comprising a probe type temperature sensor, wherein the probe type temperature sensor is arranged in the heating space and comprises a piercing part which pierces into food, a temperature sensing element which is positioned in the piercing part, and a signal line which is connected to the controller and transmits a temperature signal to the controller. According to the microwave oven capable of being heated to the fixed temperature, the piercing part of the probe type temperature sensor is utilized and can be inserted into the food for acquiring the temperature inside the food, so that whether the food is heated thoroughly can be accurately known, and excessive heating or insufficient heating is avoided to a certain degree. According to the microwave oven, the problem that the conventional microwave oven difficultly knows the food temperature is feasibly solved, the structure principle is simple and is applied to a microwave oven, the usability and the value of the microwave oven can be improved, and the microwave oven has an extremely good market prospect.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a microwave oven capable of heating to a fixed temperature. The invention belongs to the technical field of kitchen appliances. Background technique [0002] Microwave oven (microwave oven / microwave), as the name suggests, uses microwaves to cook meals. A microwave oven is a modern cooking stove that uses microwaves to heat food. Microwaves are electromagnetic waves. A microwave oven is composed of a power supply, a magnetron, a control circuit, and a cooking cavity. The power supply provides a high voltage of about 4000 volts to the magnetron. Under the excitation of the power supply, the magnetron continuously generates microwaves, and then couples into the cooking cavity through the waveguide system. Near the entrance of the cooking cavity, there is a rotatable stirrer, because the stirrer is a fan-shaped metal, which can reflect microwaves in all directions after rotating, so the microw...
