COMPRESSOR AND REFRIGERATION APPARATUS HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2019/024562
Kind Code:
A1
Abstract:
A compressor (100) and a refrigeration device, the compressor (100) comprises a cylinder (10), a piston (20), a slider (30), a first blocking member, and a second blocking member. A cylinder chamber and a slider groove are arranged in the cylinder (10). An eccentrically rotating piston (20) is arranged in the cylinder chamber, and the piston (20) and the slider (30) in the cylinder chamber define a first working chamber (41). The first working chamber (41) comprises a compression chamber (411) and a suction chamber (412). The compression chamber (411) is provided with a first exhaust port (4121), and the suction chamber (412) is provided with a first suction port (4111). The first blocking member and the second blocking member are respectively disposed on the cylinder (10), blocking both sides of the slider groove to define a second working chamber (51). The second working chamber (51) is provided with a second suction port (511) and a second exhaust port (512). The slider (30) is arranged to reciprocate in the slider groove, such that the internal pressure of the second working chamber (51) can change. The invention satisfies 5% ≤ 2L×H×e/V ≤ 80%, where H is the height of the cylinder (10), e is the eccentricity of the crankshaft, L is the width of slider groove, and V is the volume of compression chamber (411) just as the piston (20) rotates through the first suction port (4111).
