         [0034]    The working principle of the residential and commercial generator unit is as follows: the gas enters the gas system  512  through the intake system  516 , and mixes with the gas in the gas system  512 ; at this moment, the electric control box  112  makes the spark plug  504  ignite the gas in the gas system  512 , and the gas combusts to act, the produced power drives the electric system, i.e., the generator  115  to rotate and produce electricity; as the generator  115  is bound to produce heat during the rotation, its temperature needs to be lowered; for this reason, a cooling system is arranged on one side of the generator  115  for heat dissipation through a radiator which is usually a water tank  117  with a fan  116  on one side; because the heat generated during the working process of the generator  115  gathers in the casing of the residential and commercial generator unit and results in excess temperature inside the casing, the rotation direction of the fan  116  may be anticlockwise to dissipate the heat from the radiator and the exhaust pipe  118 ; the negative pressure wind generated from the rotation of the fan  116  absorbs cold air from the gas inlet, and takes away the heat generated from the running residential and commercial generator unit through the air motion inside the casing to lower the inside temperature and further avoid overheat, so that the residential and commercial generator unit can function properly; the electric control box  112  is arranged in the residential and commercial generator unit to control all of its working processes, so the operation is simplified. 
         [0035]    The casing of the residential and commercial generator unit is designed as a protruding arc, the front screen plate and the back screen plate are both processed into a form of arc, and stand columns also in a form of arc are arranged between the front screen plate, the back screen plate and the first side screen plate, the second side screen plate; the form of arc can make the available space of the residential and commercial generator unit more concentrated, and the same to the complete generator, and thus enhance the overall space utilization of the generator unit and reduce its volume and floor space.
