Electric appliance shell and air conditioner

The invention relates to an electric appliance shell which comprises a main body and a positioning frame, wherein the main body comprises an air inlet wall surface; the positioning frame is used for determining the mounting position of the air inlet wall surface, is arranged on the main body, and can be exposed to the air inlet wall surface; and the air inlet wall surface and external objects arespaced by at least a first preset distance. Through the positioning frame exposed to the air inlet wall surface, the reasonable mounting position of an electric appliance can be directly and quickly determined without the aid of other measuring tools; the moderate space between the air inlet wall surface and the external objects such as a wall and a curtain can be achieved; the electric appliancemounting efficiency can be improved; and the circumstance that the air inlet effect is influenced by the too short distance between the air inlet wall surface of the electric appliance and the wall, or the normal work of the e
