Abstract
A lubricant backflow structure of a compressor includes a casing, a scrolling set, and a transmission mechanism. An oil tank is arranged under the casing, an internally longitudinal wall of which is formed as an oil backflow passage, an inlet of which is corresponded to one side of the scrolling set for receiving a lubricant, and an outlet of which is formed above the oil tank. Thereby, when a working fluid (e.g. refrigerant) enters into the casing, it won't mix with the lubricant therein, capable of reducing oil consumption and enhancing thermally exchanging efficiency of the system.
