The control unit 610 may adjust the temperature of the refrigerating or heating cabinet inside the accommodation space 504 by adjusting the power supplied to the Peltier element 302 . The controller 610 may control the air flow rate or the air flow amount by adjusting the fan speed of the air flow unit 306, and may control the direction of the air flow by adjusting the rotation direction of the motor.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the attached claims.
