Compressor having enhanced wrap structure
A scroll compressor includes a casing; a drive motor; a rotary shaft; a fixed scroll including a fixed wrap; and an orbiting scroll eccentrically coupled to rotary shaft and including an orbiting wrap configured to engage with the fixed wrap. At least one of the fixed wrap or the orbiting wrap defines an offset section that is defined between the fixed wrap and the orbiting wrap and that is greater than an orbital radius corresponding to a distance between the fixed wrap and the orbiting wrap in a state in which a center of the fixed scroll is aligned to a center of the orbiting scroll. The offset section is disposed at a contact portion between the fixed wrap and the orbiting wrap. The contact portion has a maximum length based on a rotation angle of the rotary shaft being within a pre-set range with respect to a reference point.
