On the other hand, a plurality of wheels 140 are coupled to the lower portion of the main body 110, the sensing switch 145 is installed on the main body 110 coupled with the wheel 140, the driving unit driven by the sensing switch 145 150 is combined.

And, the lower portion of the main body 110, the non-slip fixing hole 175 is formed, the non-slip unit 160 and the brake pedal 170 is coupled, the upper end of the main body 110, the force equipment 115 is Is installed.

The multi-purpose cart 100 of the present invention configured as described above is divided into a plurality of storage parts 120 of the main body 110 fixed to the anti-slip part 160 into refrigerated and warmed room temperature storage, etc. For example, after checking the temperature displayed on the display unit 125, the temperature is set to a desired temperature. And after confirming the quantity of the water contained in the receiving unit 120 and input to the force equipment (115).

When the support heel 165 is spaced apart from the bottom by rotating the lever 167, the seller grabs the handle 119 of the multi-purpose cart 100 and pushes forward to move the body 110. When the main body 110 moves, the sensing switch 145 is turned on by sensing the position of the wheel 140 and the multi-purpose cart 100 is moved by the motor 157.

Here, the motor 157 may include a primary coil 151 which forms a magnetic field at the bottom of a driving path on which the multi-purpose cart 100 travels, and a secondary coil located inside the lower plate 113 of the main body 110. The 153 receives the induced current generated from the primary coil 151 and charges the battery 155 provided in the main body 110, and may separately charge the battery 155.

At this time, if the buyer wants to purchase the object contained in the main body 110, the seller pulls back using the handle 119, the detection switch 145 is turned off so that the multi-purpose cart 100 is stopped, brake pedal 170 When the base heel 165 supports the floor, the buyer inputs the desired number of objects to the force equipment 115. When the calculated amount is displayed on the force equipment 115, it is necessary to enter the payment method of the buyer to calculate.

Then, the number of the remaining water to be sold and displayed on the force equipment 115 is displayed, and the seller rotates the lever 167 again to allow the base heel 165 to be spaced apart from the bottom and then move the multipurpose cart 100. do.
