The present invention relates to a multipurpose cart which is easily driven by using a sensing switch and a skid prevention unit, and is able to maintain the freshness of food with a heating and cooling device, and, more specifically, to a multipurpose cart, which comprises multiple container units capable of entering and withdrawing objects and equipped with a heating and cooling device; a main body including a bottom plate equipped on the bottom of the container units; multiple wheels equipped under the main body; a handle extended and formed on the upper end part of the main body, and a driving unit driving the wheels. The heating and cooling device comprises a thermoelectric device performing a cooling or heating function according to the current; a controller controlling the current supplied to the thermoelectric device; a power supply supplying electric power to the controller; a temperature controlling unit controlling the temperature of container units; and a heat radiation plate attached to the thermoelectric device and radiating or absorbing the heat generated in the thermoelectric device. Accordingly, the freshness of food is maintained as the temperature is controllable; the card is able to be driven with a smaller force by driving the wheels with electricity; and the motor is able to be driven or stopped by sensing the relative position of the wheels by having sensing switches inside wheels. Further, the cart is able to be fixed in a dual way via a skid prevention unit, and the price and stock of holding objects are easily checked with a force facility. |
