A dish washer is provided that includes a tub that defines a space for washing dishes, a water supply unit that has a water chamber where water supplied from the outside collects, to wash the dishes, a sump that is supplied with water from the water chamber and supplies wash water into the tub, and a heat exchange passage through which the wash water in the sump flows and exchanges heat with the water in the water chamber while flowing.

Dish washer having a heat exchange passage

A robot includes a second bumper that senses an obstacle having such a height that can be passed over. Thus, the robot can pass over the obstacle without avoiding it.

A blower fan includes a shroud, a hub for guiding airflow being discharged, and a plurality of blades disposed between the shroud and the hub. A first outer diameter of a first portion, which is close to the hub, of the blade is different from a second outer diameter of a second portion, which is close to the shroud, of the blade.

Blower fan

Disclosed is an indoor unit of an air conditioner, in which at least one air inlet is formed at part of or entire bottom surface the indoor unit and an evaporator is installed between the air inlets and a blowing fan so that indoor air sucked in through air inlets passes through the evaporator and is discharged from an outlet vent formed at the front surface of the indoor unit by the operation of a blowing fan. The indoor unit of the air conditioner includes air inlets, an evaporator, a blowing fan, and an outlet vent, wherein the air inlets are formed in an opposite direction of the outlet vent for discharging cooled air; the air inlets are formed on the bottom surface of the indoor unit; indoor air flown into the indoor unit passes through the evaporator and the blowing fan and is discharge from the outlet vent; and air path from the air inlets en route to the outlet vent via the evaporator and the blowing fan is not overlapped.

Air conditioner

Provided is an improved blower fan structure in which length of blades is increased and inlet and outlet angles of the blades are optimized for highly increasing an efficiency of the blower fan. Particularly, an outer diameter of the blades is more than or equal to two times of an inner diameter thereof, for increasing the efficiency without generating a noise.

Blower fan structure

A piping structure of an air conditioner causes a looped main piping connected to a compressor of an outdoor unit of the air conditioner to be branched into two or more branch pipings within a predetermined interval of the main piping and cause the branch pipings to be jointed at an arbitrary location. According to the piping structure, it is possible to reduce a vibration by an interference phenomenon, which is generated when either a refrigerant pulsation or a periodic vibration of the compressor is divided and then combined.

Piping structure for air conditioner

A heat exchanger including first and second header tanks for receiving and discharging refrigerant. Further, the first and second header tanks are spaced apart from each other by a predetermined distance. Also include is a plurality of flat tubes each having opposite ends respectively connected to the first and second header tanks, in which each of the flat tubes has channels through which the refrigerant scatters and flows, and the channels have a different capacity from each other. Further included is a cooling member for discharging heat of the refrigerant flowing along the flat tubes.

Heat exchanger with flat tubes

Small air conditioner including a heat discharging part including a body having an air inlet in a side and an air outlet in a top surface, a condenser fitted close to an inside of the air inlet, a fan fitted under the air outlet, and a compressor fitted under the fan, wherein external air flows into the heat discharging part through the air inlet, heat exchanged at the condenser, cools down the compressor, and discharged through the air outlet, thereby permitting convenient installation and moving.
