Embodiment Construction

[0032] Hereinafter, a cross flow fan and an air conditioner according to the present invention will be described in detail with reference to the accompanying drawings.

[0033] figure 1 is a sectional view of the air conditioner according to the first embodiment of the present invention.

[0034] refer to figure 1 , the air conditioner 1 according to the first embodiment includes a housing 10 , a heat exchanger 20 , a fan 100 and a passage guide 30 . Here, the air conditioner 1 may be an indoor unit.

[0035] The housing 10 has a front suction portion 11 arranged on a front side thereof and an upper suction portion 12 arranged on an upper side thereof. The front suction part 11 and the upper suction part 12 may each be provided with a filter 13 for filtering air sucked through the upper suction part 12 . Filters 13 may be disposed at the front and upper portions of the housing 10 to cover the front suction part 11 and the upper suction part 12, respectively. Here, the fil...

Abstract

The invention provides a cross-flow fan and an air conditioner. The cross-flow fan includes: a plate-shaped fixing member; a plurality of blades fixed to one surface of the fixing member, the plurality of blades being arranged to be spaced apart from each other in the circumferential direction; an inner edge defining one side of each blade. an end portion, the inner edge extending toward the rotation axis of the blade; an outer edge defining an end opposite to the inner edge; and a protrusion protruding from the outer edge in one direction. The cross flow fan also includes a plurality of protrusions protruding toward the outer side of the blade. The invention can reduce the intensity of the vortex in the airflow discharged from the axial flow fan, so as to increase the flow rate, improve the static pressure performance and the overall efficiency of the fan, reduce noise, reduce energy consumption, and improve user satisfaction.

Description

technical field [0001] The invention relates to a cross-flow fan and an air conditioner. Background technique [0002] Generally, an air conditioner is a device used to cool or heat an indoor space. This air conditioner includes a compressor for compressing refrigerant, a condenser for condensing refrigerant discharged from the compressor, an expander for expanding refrigerant passing through the condenser, and a compressor for evaporating the refrigerant expanded in the expander. Evaporator. [0003] A condenser and an evaporator in an air conditioner may be used as a heat exchanger for exchanging heat between refrigerant and outside air, and may be provided in an indoor unit or an outdoor unit. Here, a cross-flow fan for generating air flow may be disposed on a side of the heat exchanger disposed in the indoor unit. [0004] Cross-flow fans are in the form of a circular plate provided with a plurality of blades. The cross flow fan radially discharges the air sucked in ...
