An air cooler includes a body having a top portion, a bottom portion, and a middle portion situated between the top and bottom portions. The air cooler further includes a fan disposed in the top portion of the body. The fan includes a fan hub and a plurality of fan blades centrally attached to the fan hub. The air cooler also includes a first mister disposed at a first location within the body. The first location is in front of the plurality of fan blades in the top portion of the body. The air cooler further includes a second mister disposed at a second location within the body. The second location is in front of the plurality of fan blades in the top portion of the body and different from the first location.

A pump-fan assembly of an air modification device may include a fan, a pump and a disk. The fan may include a central hub disposed on a top surface of the disk, and a plurality of blades extending from the hub towards an outer circumferential edge of the disk. The pump may include a hollow pump body defining an inner tubular passage between an inlet end and a discharge end. An impeller may be arranged at the inlet end and an outlet port may be arranged at the discharge end. The pump and the fan may be coupled at an interface between the discharge end of the pump body and a bottom surface of the disk. The outlet port may be disposed in the interface and arranged to guide a stream of pumped liquid along the bottom surface of the disk. The disk may define a liquid barrier.

BUILDING FEATURE APPLIED IN AIR-CONDITIONING APPLIANCE, capable of enriching the air with atomized water droplets in two stages, where in a first moment the water sent directly from the water supply network is pre-atomized in an appliance (8); being then delivered to the main atomizer (9), which produces the final atomization, creating an ultrafine mist that facilitates the thermal exchange between the mist and the air. The air-conditioning appliance must be associated to a fan so as to spread this mist to the room.

Provided is a refreshing device including a fan mounted onto a base. The base includes a main container for storing a fluid, a mini fan, and a nebulizer to set in motion the fluid nebulized outside of the main container toward a diffuser positioned downstream from the fan. The diffuser includes an outlet opening having a substantially annular shape, the outlet surface of the outlet opening being substantially perpendicular to the direction of airflow generated by the fan.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; a watering housing disposed inside the water tank, suctioning water of the water tank thereinto, pumping the suctioned water to an upper side when rotating, and spraying the pumped water; a watering motor providing a torque to the watering housing; and a power transmission shaft disposed inside the watering housing, connecting the watering motor and the watering housing, and delivering a torque of the watering motor to the watering housing.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a base body including an upper body and a lower body coupled to a lower part of the upper body, a water tank disposed at an upper part of the upper body, storing water, and including a water housing spraying water to the inside, a watering motor installed at the upper body and providing a torque to the watering housing; and a blower motor installed at the lower body. Here, the lower body, the upper body, and the water tank are stacked sequentially. The blower motor, and the watering motor are disposed vertically inside the base body. The watering motor, and the blower motor are spaced a predetermined interval away from each other and disposed on the same axis.
