A blower configured to circulate cold air inside a body of a refrigerator. The blower includes a casing, an impeller accommodated in the casing, and a support member configured to support the impeller against the casing. The impeller includes a disk-shaped base plate rotatably supported by the support member. The casing includes an inner circumferential surface extending so as to gradually move away from an outer circumference of the base plate toward a rotational direction of the impeller at a predetermined position around the outer circumference of the base plate, and a first case flow path between the inner circumferential surface and the outer circumference. An introduction port configured to introduce the cold air to a second case flow path branched from the first case flow path is formed on the inner circumferential surface of the casing.

Blower and refrigerator

A valve structure that may control the flow rate of a fluid when the fluid starts to be released is provided. In a valve structure including a valve sheet having two outlets to release a fluid and a valve body arranged to be rotational against the valve sheet to regulate a degree of opening of the outlet, the valve body has a fluid control recess formed in the circumferential direction whose area overlapping the outlet is changed by rotation of the valve body, and the center of the outlet is forced to deviate from a rotation trajectory of a front end portion of the fluid control recess that starts to overlap the outlet by the rotation of the valve body.

Refrigerator

A refrigerator is provided. The refrigerator includes a plurality of refrigerant flow paths, configured to reduce the drift of the refrigerant. The refrigerator includes a refrigeration cycle including a compressor, a condenser, a plurality of refrigerant flow paths branched at a downstream of the condenser, the plurality of refrigerant flow paths each including a pressure reducing device, and an evaporator connected to the plurality of refrigerant flow paths, and a processor including a switching valve configured to individually switch an open or closed state of each of the plurality of refrigerant flow paths, the processor being configured to adjust a flow rate of refrigerant flowing in each of the plurality of refrigerant flow paths by individually duty-controlling an opening and closing time of each of the plurality of refrigerant flow paths by controlling the switching valve.

Disclosed is a refrigerator that facilitates access to each evaporator and improves maintenance performance. In the refrigerator, a different temperature of cold air cooled by each evaporator is brought into each cooling chamber with a different temperature range and different humidity range. The refrigerator includes a main refrigerator body including a machine room and a cooling chamber, an evaporator contained in the machine room, and a cooling unit detachably mounted in the machine room and including a compressor, a condenser, and an insulation member, wherein the cooling unit, while mounted in the machine room, has the insulation member tightly contact an inner wall of the machine room to form an insulation space, and the evaporator is contained in the insulation space.

Refrigerator including a detachably mounted cooling unit

A refrigerator includes a storage chamber, an evaporator configured to cool the storage chamber, and an air passage through which cold air generated by the evaporator flows. The air passage includes a blower fan configured to blow the cold air to the storage chamber, and a trap part in which warm air generated by a defrosting operation stays, such that warm air generated by the defrosting operation is prevented from being introduced into the inner space of the refrigerator through the air passage. The refrigerator reduces the defrosting operation time, efficiently prevents increase of the inner temperature of the refrigerator due to warm air during the defrosting operation, reduces a temperature difference in inner temperature of the refrigerator, and prevents food stored in the refrigerator from being rotten due to a temperature change.
