[Claim 1] A compressor comprising:
a container, wherein a mixture liquid of a refrigerating machine oil and a refrigerant is reserved in a bottom section of the container;
an electric motor housed in the container;
a crankshaft being a rotation shaft of the electric motor, the crankshaft drawing the mixture liquid from the bottom section of the container during rotation; and
a liquid level sensor including an elongated electrode for detection of whether a liquid level of the mixture liquid reaches a reference height, wherein both ends of the electrode in a longitudinal direction are located at different positions from each other in a rotation direction of the crankshaft.
[Claim 2] The compressor according to claim 1, wherein the longitudinal direction of the electrode is orthogonal to a perpendicular line from a center of the electrode to a center axis of the crankshaft.
[Claim 3] The compressor according to claim 1 or 2, wherein the longitudinal direction of the electrode is orthogonal to an axial direction of the crankshaft. [Claim 4] The compressor according to any one of claims 1 to 3, wherein the electrode has a rectangular plate shape such that a short side direction of the electrode coincides with an axial direction of the crankshaft.
[Claim 5] The compressor according to any one of claims 1 to 3, wherein the electrode has a cylindrical shape opening at both ends thereof in the longitudinal direction. [Claim 6] The compressor according to any one of claims 1 to 5, wherein the electrode is curved in an arc shape along the rotation direction of the crankshaft. [Claim 7] The compressor according to any one of claims 1 to 6, wherein,
a suction section to suction the mixture liquid through an opening is provided

at a lower section of the crankshaft, and
the liquid level sensor includes, as the electrode, a pair of elongated electrodes to face each other in a radial direction of the crankshaft, respective lower ends of the elongated electrodes being at positions higher than the opening of the suction section. [Claim 8] The compressor according to any one of claims 1 to 7, further comprising:
a plate disposed inside the container, the plate separating, in an axial direction of the crankshaft, a space where the electric motor is housed and a space where the liquid level sensor is disposed.
[Claim 9] The compressor according to any one of claims 1 to 8, wherein the liquid level sensor is disposed at at least one place on an inner wall of the container. [Claim 10] The compressor according to any one of claims 1 to 8, wherein the liquid level sensor is disposed at two or more places on an inner wall of the container in the rotation direction of the crankshaft. [Claim 11] A refrigerating cycle apparatus comprising:
the compressor according to any one of claims 1 to 10; and
a controller to detect, using the liquid level sensor, whether the liquid level of the mixture liquid reaches the reference height and to control an operation of the compressor according to a detection result.
