Definitions
- a compressor with an oil blocking device therefor are disclosed herein.
- Compressors are known. However, they suffer from various disadvantages.
- a compressor and oil blocking device therefor are provided which are capable of preventing oil from spreading onto, for example, a balance weight, which are capable of preventing oil from being excessively sucked into a compression device by a separating device disposed between a driving motor and the compression device, and which are capable of constantly maintaining a predetermined amount of oil in compression chambers regardless of a rotational speed of the driving motor by directly supplying oil to a bearing surface and the compression chambers and by easily discharging gas from an oil drain passage.
- a trochoid gear pump may be used to smoothly supply oil to the compression device.
- a synchronous reluctance motor may be used to enhance a performance of the compressor and to expand a driving region of the compressor.
- the casing 10 includes a body 11, which may have having a cylindrical shape.
- the driving motor 20 and the compression device 30 may be installed at upper and lower portions of an inner circumferential surface of the casing 10.
- the casing 10 may further include an upper cap 12 and a lower cap 13 that hermetically cover upper and lower sides of the body 11.
- the main frame 14 may include an axial hole 14a penetratingly formed at a center thereof, an oil pocket 14b, which may be disposed on an upper end of the axial hole 14a to collect oil sucked through the rotational shaft 23, an oil collecting hole 14c, which may be disposed at one side on an outer circumferential surface of the oil pocket 14b to collect the oil inside the oil pocket 14b to the casing 10, and an oil supplying hole 14d, which may be disposed at another side on the outer circumferential surface of the oil pocket 14b to partially supply the oil inside the oil pocket 14b to the compression chambers P.
- An oil blocking device or unit 17 that prevents oil from spreading onto a balance weight 24 by receiving the axial hole 14a may be disposed adjacent a lower surface of the main frame 14.
- the oil drain guide member 19 may have a rectangularly shaped sectional surface, and is coupled to the casing 10 by welding so that an opening thereof forms the oil drain path 19a together with an inner circumferential surface of the casing 10.
- the oil drain guide member 19 may be formed to be tapered so that oil collected through the oil drain passage 18a may be smoothly drained.
- an outlet of the oil drain guide member 19 may extend lower than an upper end of the coil 21a of the driving motor 20 so that drained oil may be prevented from being mixed with spread oil or refrigerant.
- the driving motor 20 may include a stator 21 fixed to the casing 10 that receives power from outside, a rotor 22 disposed in the stator 21 with a pre-determined air gap therebetween and rotate by being interworked with the stator 21, and a rotational shaft 23 coupled to the rotor 22 by, for example, shrinkage fit to transmit a rotational force generated by the driving motor 20 to the compression device 30.
- the rotational shaft 23 may be provided with an oil passage 23a therein penetratingly formed in a shaft lengthwise direction.
- Oil passing holes 23b through which sucked oil may be supplied to the axial holes 14a and 15a of the main frame 14 and the sub-frame 15 may be formed in a radial direction at upper and lower sides of the oil passage 23a.
- One or more gas discharge holes 23c through which gas sucked through the oil passage 23a together with oil may be discharged outside the oil passage 23a may be formed between the oil passing holes 23b.
- the trochoid gear pump may include the inner gear 25a, the outer gear 25b, a pump cover 25c, and a mesh box 25d.
- a thrust plate 25e may be installed between the rotational shaft 23 and the oil pump 25. The thrust plate 25e may be fixed to a through hole 15b of the sub frame 15.
- the trochoid gear pump may have a plurality of inlets with height differences so that a predetermined amount of oil may always be pumped regardless of a mixed degree between oil and refrigerant. For instance, when oil and refrigerant are mixed with each other at an acceptable state, both the oil and the refrigerant are pumped through both inlets. On the contrary, when the refrigerant and the oil are mixed with each other at an inferior state in which the refrigerant is disposed below the oil, only the refrigerant may be pumped through an inlet disposed at a lower side resulting in oil deficiency. However, if the inlets are disposed with height differences, the oil disposed at an upper side may be pumped together with the refrigerant, thus enhanceing a lubricating performance.
- the orbiting scroll 32 may be formed so that an orbiting wrap 32a forming the pair of compression chambers P together with the fixed wrap 31a of the fixed scroll 31 may have an involute shape at an upper surface of the plate portion 31d of the orbiting scroll 32.
- a boss portion 32b coupled to the rotational shaft 23 and receiving a rotational force generated by the driving motor 20 may be formed at a center of the lower surface of the plate portion 32d.
- the driving motor may be implemented as a synchronous reluctance motor
- the compressor may have an enhanced performance when rotated at a low speed.
- a heat emitting amount of the motor may be decreased, expanding a driving region of the compressor.
- Embodiments disclosed herein provide a scroll compressor capable of always maintaining a predetermined amount of oil regardless of a rotational speed of a driving motor.
