Detailed description of the invention
Closed-type compressor (1) comprises housing (2), and its support is arranged on element wherein, and the oil of lubricated displaceable element is placed in one; Motor, it has rotor (3) and stator (4); Bent axle (5), it is installed to the core of rotor (3) and rotatablely moving of rotor (3) is sent to piston in the mode of buckle combination in rotation direction, its lower end is immersed in the oil in housing (2), and is wherein arranged on axial direction and starts to open into the gap (B) in its main body by its lower end; Oil suction element (6), it is cylindrical, is arranged to enter bent axle through the lower end of bent axle (5) inner and concentric with bent axle (5), and the oil in housing (2) is transported to bent axle (5); Support (7), it is upper that oily suction element (6) is positioned at support (7), and support (7) is connected to stator (4), is limited in the motion of oily suction element (6) in motor operation process; At least one connector (8), it is upper that it is fixed on support (7), and extend in oily suction element (6), makes gap remain between the two and allow the radial motion of oily suction element (6); With at least one retainer (9), it extends part in oil-feed suction element (6) by connector (8) and is fastened to oily suction element (6) and limits the movement of oily suction element (6) and restriction connector (8) at motion (Fig. 1 of direction up or down with in the vertical direction, Fig. 2, Fig. 3).
In household electrical appliance, preferably in cooling device, provided by reciprocal closed-type compressor (1) for the circulation of the cold-producing medium that freezes. In these closed-type compressors (1), carry out the friction loss of the lubricated displaceable element with minimizing compressor (1) in running, stop wearing and tearing, and remove fricative heat. The lower end of bent axle (5) is immersed in the oil of housing (2), and oil in housing (2) is sucked and is entered in bent axle (5) by the effect of centrifugal force. Oil by arranged concentric the oily suction element (6) in bent axle (5) in upward direction by bent axle (5) and be transported to displaceable element and the sliding bearing on motor. Distance between connector (8) allows oily suction element (6) radial motion. Oil suction element (6) moves together with the oil moving upward due to centrifugal action in motor operation process, and is centered in the inside of bent axle (5). Therefore, the greasy property of closed-type compressor (1) increases.
In the process moving upward at oil, oil applies force in the oily suction element (6) of its contact, and oily suction element (6) is moved upward. Connector in motor operation process (8) keeps static by being fastened to support (7). The oily suction element (6) that is fastened to connector (8) is limited at the inner retainer (9) that moves through of bent axle (5), and therefore oil is easily transported to displaceable element (accompanying drawing 4). Retainer (9) is secured to the inner surface of oily suction element (6). Upwards moving downward by retainer (9) of connector (8) stops. By connector (8), at oily suction element (6) internal rotating, oily suction element (6) is centered in bent axle (5) inside.
In an embodiment of the present invention, connector (8) is fastened to oily suction element (6) from one end by retainer (9), is fastened to support (7) from the other end. The connector (8) that is connected to support (7) in installation process from one end is placed on oily suction element (6), and is secured to oily suction element (6) from the other end by retainer (9). Therefore, the moving both vertically of oily suction element (6) of the oily impact being moved upward in motor operation process is limited, and the greasy property of closed-type compressor (1) increases (Fig. 4, Fig. 5).
In an embodiment of the present invention, connector (8) extends along oily suction element (6). Connector (8) extends towards the top of oily suction element (6) from support (7). Therefore, connector (8) longitudinally keeps oily suction element (6), and limits oily suction element in the inner motion (Fig. 6, Fig. 7) of bent axle (5).
In the distortion of the present embodiment, retainer (9) comprises at least one chamber (10) that is arranged on oily suction element (6) top place, with at least one extension (11), described at least one extension (11) forms and is resisted against on the top of oily suction element (6) by the end of bending connector (8). Be installed in the process of closed-type compressor (1) at connector (8), connector (8) is secured to support (7), and through oily suction element (6). Extension (11) forms by the end of bending connector (8). Stop connector (8) to depart from oily suction element (6) (Fig. 5, Fig. 6) by extension (11).
In the distortion of the present embodiment, retainer (9) comprises at least one baffle plate (16), and it stops oily suction element (6) and connector (8) to move downward. In the time that connector (8) is placed in oily suction element (6), extension (11) is resisted against on baffle plate (16). Stop connector (8) down sliding by baffle plate (16).
In the distortion of the present embodiment, retainer (9) comprises at least one lid (12), and it stops connector (8) to move up by being arranged in oily suction element (6). Lid (12) is exerted pressure upper at extension (11), therefore stops extension (11) to move up. Lid (12) and baffle plate (16) carry out size design pari passu.
In an embodiment of the present invention, closed-type compressor (1) comprises connector (8), it has at least one projection (13), provide connector (8) to be fastened to support (7), and support (7) has groove (14), this projection (13) is seated in wherein. Be seated in groove (14) by projection (13), connector (8) is provided as being fastened to support (7) upper (Fig. 5).
In an embodiment of the present invention, projection (13) comprises at least one bend (15), and it stops projection (13) releasing slots (14). The bend (15) above forming to be resisted against support (7) through groove (14) by the end by bent projection (13), projection (13) is prevented from departing from this groove (14) (Fig. 5).
In an embodiment of the present invention, the form that connector (8) is line. This linear formula provides connector (8) mobile flexibility.
By the present invention, closed-type compressor (1) is disclosed, there is connector (8), it can make described oily suction element (6) be installed to support (7), and retainer (9), can make oily suction element (6) radial motion in motor operation process. Therefore, in motor operation process, stop oily suction element (6) to contact with bent axle (5), therefore stop its distortion.
