Abstract

A safety device of a microwave oven comprises a load of the microwave oven, a first switch for switching on-off the load power supply of the microwave oven, a load of a mechanical device, a second switch for switching on-off load power supply of the mechanical device, a feedback loop of the current the mechanical load uses and a microcomputer for controlling the first and second switches according to the data detected by the feedback loop. When the temperature control element in the present invention can't cut off the power supply for supplying the load of the mechanical device immediately, the microcomputer can cut off the power supply for supplying the load of the mechanical device via the signal detected by the above feedback loop to prevent the device from being damaged.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a safety device for the microwave oven. Background technique [0002] A microwave oven is a cooking machine that uses the heat of microwaves or heaters to heat food. Present microwave ovens not only have the function of heating food with the heat of microwaves or heaters, but also have multiple functions such as toasting and coffee making. [0003] The microwave oven having multiple functions as described above is controlled by a microcomputer when using a microwave or a heater, but is controlled by a mechanical method when toasting or making coffee. [0004] As mentioned above, the microwave oven having various functions cannot check the safety of the mechanical device, thus causing disadvantageous problems such as damage to the product. Contents of the invention [0005] The purpose of the present invention is to overcome the above-mentioned deficiencies in the technology, and to provide...
