| 20100329906 | MOTOR FOR COMPRESSOR AND HERMETIC COMPRESSOR HAVING THE SAME - Disclosed are a motor for a compressor and a hermetic compressor having the same. An aluminum coil cheaper than a copper coil is used in the motor for the compressor, a ratio between the aluminum coil and a stator core is set, and sectional areas of main and sub slot portions of the stator core and the numbers thereof are adjusted to be suitable for usage conditions, whereby fabricating costs of the motor for the compressor and the hermetic compressor can drastically be reduced and efficiencies thereof can be improved. | 12-30-2010 |
| 20100329907 | MOTOR FOR COMPRESSOR AND HERMETIC COMPRESSOR HAVING THE SAME - Disclosed are a motor for a compressor and a hermetic compressor having the same. An aluminum coil is used in the motor for the compressor, and sectional areas of main and sub slot portions and the numbers thereof are adjusted to be suitable for usage conditions, whereby fabricating costs of the motor for the compressor and the hermetic compressor can drastically be reduced. Also, as the aluminum coil of the motor for the compressor is coupled to a lead wire in a welding manner, the breaking of the aluminum coil, which may occur when coupling the aluminum coil to the lead wire can be prevented, resulting in improvement of assembly reliability of the reciprocating compressor. | 12-30-2010 |
| 20110085926 | MOTOR FOR COMPRESSOR AND HERMETIC COMPRESSOR HAVING THE SAME - Disclosed are a motor for a compressor and a hermetic compressor having the same. An aluminum coil cheaper than a copper coil is used in the motor for the compressor, to thusly reduce a fabricating cost. Also, a ratio of a height of end coil of a coil to an inner diameter of a stator is appropriately designed or a ratio of an entire area of slot portions to the inner diameter of the stator is appropriately designed, and simultaneously a ratio of the inner diameter of the stator to a width of the tooth portion is appropriately designed, so as to previously prevent a deterioration of damping effect, increase in noise, lowering of efficiency, reduction of driven torque, all caused due to the use of the aluminum coil. | 04-14-2011 |

| 20080196266 | Ductless dryer - A ductless dryer includes a main body, a drum rotatably installed at the main body, a heat exchanger for removing moisture from air exhausted from the drum, a circulation duct to flow the air exhausted from the drum into the heat exchanger, an exhaust duct to flow the air exhausted from the heat exchanger outside the dryer; and a noise reduction portion to attenuate noise propagation through the exhaust duct. As the ductless dryer is provided with the noise reduction portion, the noise propagation through the exhaust duct exposed into the room and the noise of the entire ductless dryer can be attenuated at the same time, whereby a quieter room environment can be provided. | 08-21-2008 |
| 20080196268 | FILTER CLEANING APPARATUS AND DUCTLESS DRYER IMPLEMENTING THE SAME - Disclosed is a filter cleaning apparatus and a ductless dryer adopting the same, the dryer having a main body, a drum rotatably mounted at the main body, a hot air supplying unit supplying hot air into the drum, a heat exchanger condensing and removing moisture contained in air exhausted from the drum, a circulation duct conducing the air exhausted from the drum to the heat exchanger, a filter installed in the circulation duct and filtering foreign substances contained in the air discharged from the drum, and a filter cleaning apparatus removing the foreign substances caught by the filter, thereby enhancing a user's convenience and reducing indoor air contamination which may occur in the course of removing the foreign substances. | 08-21-2008 |
| 20080201977 | Heat exchanger and condensing type laundry dryer having the same - A condensing type dryer uses a heat exchanger in which condensed water can be smoothly discharged through a water-discharging slot formed in a rear end portion of a rear cover of the heat exchanger. The water-discharging slot prevents an air flowing resistance which can be caused by condensed water pooling at the rear end portion of the rear cover. Also, leakage-preventing walls enhance the heat exchanging function by ensuring a uniform flow of cold external air through the heat changer. The leakage-preventing walls prevent external air from leaking around the lateral edges of the heat exchanger. | 08-28-2008 |
| 20100005680 | DUCTLESS DRYER - A ductless dryer includes a sealing unit for preventing a leakage of lint through a gap of a filter installation portion. The sealing unit includes a sealing protrusion formed at the filter, a sealing recess disposed at a filter installation duct of the circulation duct for inserting the sealing protrusion thereinto, and a sealing member inserted into the sealing recess and contacting the sealing protrusion. Accordingly, the ductless dryer according to the present invention can prevent the leakage of lint through a gap of a filter installation portion and the malfunction of the ductless dryer by leaked lint, thereby enhancing reliability of the dryer. | 01-14-2010 |
