A digital audio signal player includes a reproducing unit to pick a disc audio signal which is stored in a disk, and a digital signal processor for controlling input and output of the disc audio signal of the memory. Thus, when the system processing unit receives the trigger signal of the trigger switch after the contact member is pressed to contact the trigger switch, the system processing unit drives the digital signal processor to modulate the disc audio signal stored in the memory according to the detected signal of the sensor so as to produce a special audio signal output.

The inner pot of an electric fryer includes an annular electric heating tube at the bottom. Two ends of the electric heating tube are separated from each other, forming there between a gap that forms the coolest section of the inner circumference at the bottom of the inner pot. An oil gathering groove is provided at the coldest section and communicates with the bottom center of the inner pot by means of an oil passage passing through the gap between the two ends of the electric heating tube. The inner pot is designed to have a bottom slanting downward toward the oil-gathering groove after combined with an outer pot. Thus, the remaining oil in the inner pot is able to flow into the oil gathering groove along the inner wall and through the oil passage to prevent remaining oil inside from accumulating near the electric heating tube and catching fire.
