A laundry treating apparatus including a dryer including a first cabinet having a first door and a first drum rotatably mounted in the first cabinet for receiving laundry; a washing machine including a second cabinet having a tub disposed in the second cabinet and a second drum rotatably mounted in the tub for receiving laundry; a refresher including a third cabinet having an inner space for receiving laundry; a duct system for supplying air into the first drum, for supplying air into the inner space of the refresher, and a heat exchange channel connected to the duct system; and a heating device for heating air passing through the heat exchange channel, thereby supplying air to a plurality of laundry treating machines by using a single heating device.

A laundry treating apparatus includes a dryer including a first cabinet and a first drum rotatably mounted in the first cabinet; a washing machine including a second cabinet vertically disposed with respect to the first cabinet, a tub disposed in the second cabinet, and a second drum rotatably mounted in the tub; a refresher including a third cabinet disposed on one side of the first cabinet and the second cabinet, and having an inner space for receiving laundry; a heating device disposed above the first drum and the second drum, and heating air supplied into the inner space of the refresher; and a supply air duct connecting the heating device and an upper portion of the refresher, thereby supplying hot air to the upper portion of the refresher.

A laundry treating apparatus includes a dryer disposed in an indoor space; a washing machine vertically disposed with respect to the dryer; a refresher disposed on one side of the dryer and the washing machine; and a heating device heating air supplied to at least one of the dryer, the washing machine, and the refresher. The heating device includes a plurality of compressors, and controls a number of compressors to be operated and an RPM of the operated compressors, according to a cycle status of the dryer, the washing machine, and the refresher.

A rotary compressor is provided that may include a casing, a cylinder, a main bearing, a sub bearing, a rotational shaft, a roller, and at least one vane. The cylinder may include at least one elastic deformation unit to absorb impact with the at least one vane. With this structure, a collision force caused due to chattering of the at least one vane may be absorbed to suppress or prevent friction loss and/or wear between the cylinder and the vane, thereby enhancing compressor efficiency, reducing vibration noise, and enabling fast initial actuation.

Rotary compressor

A laundry treating apparatus including an outer case; an inner case disposed in the outer case and providing a laundry receiving space; a supply air hole communicating with the laundry receiving space; a heat exchange channel having an inlet end where air is introduced and a discharge end where the air is discharged; a heating device for heating air passing through the heat exchange channel; and a supply air duct connecting the discharge end of the heat exchange channel and the supply air hole, the supply air duct is disposed in a rear of the inner case.

A compressor including a hinge recess formed at a rolling piston and a hinge protrusion formed at a vane to be inserted into the hinge recess. A diameter of the hinge protrusion is greater than an interval between both ends of an opening of the hinge recess. A bearing surface, which comes in contact with an inner circumferential surface of the hinge recess, of an outer circumferential surface of the hinge protrusion, has a circumferential surface below 90° at both sides, respectively, based on a central line in a lengthwise direction of the vane. This structure may facilitate cutting and grinding of the bearing surface so as to produce machining costs, and also improve a machining degree and thus stabilize behaviors of the rolling piston and the vane so as to enhance compression efficiency.

Rotary compressor with vane coupled to rolling piston

Disclosed herein is a rotary engine a supply flow passage provided in the housing to allow the lubricating oil to move therethrough, a sealing part arranged to contact the rotor to selectively close the supply flow passage, and an elastic part configured to press the sealing part toward the combustion chamber.

Rotary engine

The present invention provides a rotary engine comprising: a housing provided with three lobe accommodation parts; a rotor which is provided with two lobes continuously accommodated in the lobe accommodation parts, has an intake storage part communicating with an intake port provided on the front surface-side, and has an exhaust storage part communicating with an exhaust port provided on the rear surface-side; an intake-side housing cover provided with an intake hole communicating with the intake storage part; an exhaust-side housing cover provided with an exhaust hole communicating with the exhaust storage part; and a crankshaft, wherein the flow of an exhaust gas into a stroke chamber during an intake stroke is reduced by preventing the exhaust storage part, at a portion of a section in which the exhaust port is open, from communicating with the exhaust hole during the intake stroke.

The present disclosure relates to a rotary engine having a crankshaft with an improved structure, the rotary engine including a housing, a rotor, housing covers, and a crankshaft installed to penetrate through the rotor so as to receive rotational force from the rotor, wherein the crankshaft includes a first member extending in one direction and having an insertion groove recessed in one side surface thereof, a second member extending to penetrate through a center portion of the housing and provided with a protruding portion on one end thereof to be fixedly inserted into the insertion groove, and a coupling member interposed at a position where the insertion groove and the protruding portion overlap each other such that the first member and the second member are closely coupled to each other.

A rotary engine having a crankshaft, a housing provided with lobe accommodating portions arranged to surround the crankshaft, and combustion chambers communicating with the lobe accommodating portions, a rotor rotatable eccentrically with respect to the crankshaft and provided with lobes continuously accommodated in the lobe accommodating portions, a housing cover provided with a bearing portion through which the crankshaft is inserted so as to be rotatably supported, and a lubricating unit to supply oil to the bearing portion, wherein the lubricating unit includes an oil pan to accommodate oil therein, an oil pump to pump up oil filled in the oil pan, and an oil supply passage having both ends located in the oil pump and the bearing portion, respectively, is provided. This structure may allow direct and effective lubrication of the bearing portion, and can employ a journal bearing.

Rotary engine with oil pump

Disclosed is a compressor. A lubrication surface, which has the same curvature as an inner circumferential surface curvature of a cylinder and which has a predetermined circumference length, is formed on an outer circumferential surface of a roller contacting an inner circumferential surface of the cylinder. With such a configuration, since the outer circumferential surface of the roller contacting the inner circumferential surface of the cylinder come in surface-contact with each other, an oil film is formed between the roller and the cylinder with a wide area. This can reduce a frictional loss.
