1. A vacuum adiabatic body of an appliance including a machine chamber that is provided on a lower portion of a rear side of the appliance, the vacuum adiabatic body comprising:
a first plate which defines at least a portion of a first wall for a first space;
a second plate which defines at least a portion of a second wall for a second space;
a support configured to maintain a distance between the first plate and second plate and disposed next to or adjacent to the first plate;
a sheet configured to seal a third space between the first plate and the second plate such that the third space is in a vacuum state; and
at least one reinforcing frame which is coupled to at least one of the first plate or the second plate to reinforce a strength of the vacuum adiabatic body,
wherein the reinforcement frame includes first and second upper and lower frames of the machine chamber extending in the third space in a vertical direction to be adjacent to, respectively left and right sides of the machine chamber and defining edges of a side opening of the machine chamber,
wherein the vacuum adiabatic body comprises a front edge that defines an opening to access the first space,
wherein the vacuum adiabatic body further comprises:
a pair of outer front frames coupled to the front edge at left and right of the front edge, the pair of outer front frames being provided separately from the first and second upper and lower frames of the machine chamber, and
an external cover provided on an outer surface of the second plate and having a plane to shield the side opening of the machine chamber and one of the pair of outer front frames,
wherein at least one of the pair of outer front frames includes a first part extending in the vertical direction and a second part bent from the first part and extending in a rear direction, the first part and the second part being disposed in the second space,
wherein the external cover is fastened to the outer surface of the second plate and at least the one of the pair of outer front frames,
wherein the reinforcement frame further includes a first frame provided in the third space, and a second frame provided in the first space, and
wherein the first frame is attached to the second plate, and the second frame is attached to the first plate and has a bent shape.
