Vending machine with temperature control system

Abstract

A temperature control system mounted in the chassis of a vending machine is quickly detachable as a single unit. The chassis comprise a base panel and a mounting panel substantially parallel to the base panel. The temperature control system comprises a bracket, a compressor, a condenser, and an evaporator. The bracket comprises a supporting plate and a pair of mounting plates fixed to the supporting plate. The compressor and the condenser are mounted on the supporting plate. The evaporator is attached to the pair of mounting plates and located above the compressor and the condenser. The pair of mounting plates engages with the pair of first gaps when the temperature control system is mounted in the chassis and the pair of mounting plates is simply disengaged away from the pair of first gaps when the temperature control system needs to be detached from the chassis.
