A cup holder is provided, in which a control portion calculates a container-housing-portion temperature gradient ΔT based on a temperature T detected by a thermistor disposed inside a convex portion located on a bottom portion of a container housing portion. The control portion automatically carries out heating or cooling relative to the container housing portion based on that the container-housing-portion temperature gradient ΔT is a heating reference temperature gradient α or above, or is a cooling reference temperature gradient β or below. Thus, determinations of the heating or cooling is carried out based on only the container-housing-portion temperature gradient ΔT, so that heating or cooling control can be accurately carried out only by one temperature sensor.

1. A cup holder, comprising: a container housing portion adapted to internally house a container;a thermoelectric element adapted to heat or cool the container housed in the container housing portion by applying current;a temperature measurement device measuring a temperature of the container housing portion;a main switch switching a power source of the cup holder;a mode changeover switch switching a heating or cooling treatment; anda control portion controlling the thermoelectric element to carry out the heating or cooling treatment,wherein the control portion determines a manual mode to manually carry out the heating or cooling treatment when the main switch is turned on, and determines an automatic control mode to automatically carry out the heating or cooling treatment when the main switch is turned off,in the manual mode, the control portion controls the thermoelectric element to carry out the heating treatment when the mode changeover switch selects a heating mode, and controls the thermoelectric element to carry out the cooling treatment when the mode changeover switch selects a cooling mode, andin the automatic control mode, the control portion calculates a container-housing-portion temperature gradient per unit time based on the temperature of the container housing portion detected by the temperature measurement device, and controls the thermoelectric element based on a comparison between the container-housing-portion temperature gradient and a reference temperature gradient as a determination criterion of applying the current for heating or cooling the thermoelectric element. 2. A cup holder according to claim 1, wherein the control portion stores a heating reference temperature gradient which becomes the determination criterion of applying the current for heating the thermoelectric element in the reference temperature gradient, and in the automatic control mode, in case the container-housing-portion temperature gradient is equal to or larger than the heating reference temperature gradient, the current is applied to the thermoelectric element adapted to heat the container housed in the container housing portion. 3. A cup holder according to claim 2, wherein the control portion stores a cooling reference temperature gradient which becomes the determination criterion of applying the current for cooling the thermoelectric element in the reference temperature gradient, and in the automatic control mode, in case the container-housing-portion temperature gradient is equal to or smaller than the cooling reference temperature gradient, the current is applied to the thermoelectric element adapted to cool the container housed in the container housing portion. 4. A cup holder according to claim 3, wherein the current is not applied to the thermoelectric element in case the container-housing-portion temperature gradient is smaller than the heating reference temperature gradient, and is larger than the cooling reference temperature gradient. 5. A cup holder according to claim 4, further comprising a container detecting switch adapted to detect whether the container is housed in the container housing portion or not, wherein in the automatic control mode, when the container is detected in the container housing portion through the container detecting switch, and the container-housing-portion temperature gradient is equal to or larger than the heating reference temperature gradient, the control portion controls the heating treatment to continue until the temperature of the container housing portion reaches a target heating temperature, andin the automatic control mode, when the container is detected in the container housing portion through the container detecting switch, and the container-housing-portion temperature gradient is equal to or smaller than the cooling reference temperature gradient, the control portion controls the cooling treatment to continue until the temperature of the container housing portion reaches a target cooling temperature. 6. A cup holder according to claim 5, wherein in the automatic control mode, when the container is not detected in the container housing portion after the control portion starts controlling the heating treatment, the control portion continues the heating treatment for a predetermined time, and when the container is not detected in the container housing portion after the control portion starts controlling the cooling treatment, the control portion continues the cooling treatment for the predetermined time. 7. A cup holder according to claim 6, wherein the container detecting switch includes a shaft body, a flap rotatably arranged on the shaft body, a torsional spring attached around the shaft body, and a contact point arranged above the flap, wherein when the flap is urged with an urging force of the torsional spring and is positioned at a horizontal position to contact the contact point, the container detecting switch detects that the container is not housed in the container housing portion, and when the flap is pressed against the urging force of the torsional spring and is positioned at a vertical position to be apart from the contact point, the container detecting switch detects that the container is housed in the container housing portion. 8. A cup holder according to claim 1, wherein the temperature measurement device is embedded in the container housing portion. 9. A cup holder according to claim 1, wherein the thermoelectric element is a Peltier element. 10. A cup holder according to claim 1, wherein in the heating mode of the manual mode, the heating treatment continues until the temperature of the container housing portion detected by the temperature measurement device reaches a target heating temperature, and when the temperature of the container housing portion becomes lower than a re-heating reference temperature, the control portion controls a heat-retention treatment to maintain the temperature of the container housing portion between the target heating temperature and the re-heating reference temperature, and the control portion controls the heat-retention treatment until the main switch is turned off; andin the cooling mode of the manual mode, the cooling treatment continues until the temperature of the container housing portion detected by the temperature measurement device reaches a target cooling temperature, andwhen the temperature of the container housing portion becomes lower than a re-cooling reference temperature, the control portion controls a cold-retention treatment to maintain the temperature of the container housing portion between the target cooling temperature and the re-cooling reference temperature, and the control portion controls the cold-retention treatment until the main switch is turned off.
