Abstract:
1. A soup maker comprising: a container including a hollow interior having an opening in an upper end thereof; an upper lid removably engaged in the opening of the container; a container seat assembly including an annular seat, a thermally conducting pan, a cutter, a transmission unit, a heating pan, a power supply terminal, and a temperature sensor, with the annular seat including an annular wall defining a space, with an inner flange formed on an inner periphery of the annular wall and dividing the space of the annular seat into an upper portion and a lower portion, with the container having a lower end fittingly received in the upper portion of the space of the annular seat, with a positioning plate formed on the inner periphery of the annular seat and located below the inner flange, with the thermally conducting pan mounted in the annular seat and adapted for receiving food, with the thermally conducting pan including an outer periphery engaged with the inner flange, with the thermally conducting pan further including a through-hole in a central portion thereof, with the cutter mounted above the thermally conducting pan, with the transmission unit including a transmission shaft, with the transmission shaft having a top end extended through the through-hole of the thermally conducting pan and coupled with the cutter, with the heating pan located below the thermally conducting pan and abutting a bottom of the thermally conducting pan, with the heating pan connected to a heating tube, with the heating tube generating heat when supplied with electricity, with the heating pan further including a hole in a central part thereof, with the transmission unit extending through the hole of the heating pan, with the power supply terminal located below the heating pan and having a top end electrically connected to the heating tube, with the temperature sensor located below the heating pan and including an end abutting the heating pan to directly detect a temperature of the heating pan, with the temperature sensor including a coupling section; and a base unit including a base, a motor, and a control circuit board, with the base including an upper end having a coupling portion, with the coupling portion coupled with the container seat assembly, with the motor and the control circuit board mounted below the coupling portion, with the control circuit board adapted to connect with an external power source, with the control circuit board operable to adjust temperature detection and to control operation of the motor and the heating tube, with the coupling portion including a mounting face having a central portion, with a driving shaft mounted to the central portion of the mounting face and driven by the motor, with the driving shaft coupled to the transmission shaft of the transmission unit, with the mounting face further including a terminal hole and a sensor hole, with a positioning switch provided on the mounting face and pressable by the positioning plate, with the positioning switch electrically connected to the control circuit board, with the control circuit board operable to control the motor and the heating tube when the positioning switch is pressed, with the positioning plate pressing against the positioning switch when the annular seat is coupled with the coupling portion of the base, with the power supply terminal extending into the terminal hole, and with the coupling section of the temperature sensor extending into the sensor hole, with the thermally conducting pan including a hollow peg at the central portion thereof, with the hollow peg including the through-hole of the thermally conducting pan, with the transmission unit further including a bearing, a shaft sleeve, a transmission collar, and a conic sealing cap, with the bearing mounted around the transmission shaft, with the shaft sleeve fittingly received in the hollow peg and receiving the bearing, with the transmission collar mounted to a lower end of the transmission shaft and coupled to the driving shaft, with the conic sealing cap mounted between a lower end of the shaft sleeve and the transmission collar, and with the base including an inner wall protruding from the mounting face, with a lower end of the annular wall of the annular seat engaged with the inner wall of the base, with the base further including an outer wall protruding from the mounting face and surrounding the inner wall, with a compartment defined between the inner and outer walls, with the outer wall of the base including a notch.
