Abstract

An air conditioner includes an indoor unit. The indoor unit includes a first housing, a fan, a piping box, and a nano water ion generating device. The first housing includes a first accommodating space, a return air inlet, and an air outlet. The fan is opposite to the return air inlet. The piping box is disposed in the first accommodating space and proximate to the air outlet. The nano water ion generating device is located at a position of the first housing proximate to the air outlet. The nano water ion generating device includes a nano water ion outlet. The nano water ion generating device and the piping box are communicatd through a vent therebetween. Air in the piping box enters the nano water ion generating device through the vent, and air with the nano water ions is sent indoors through the nano water ion outlet.

an outdoor unit;
and
an indoor unit connected to the outdoor unit and including:
a first housing including a first accommodating space, a return air inlet, and an air outlet;
the return air inlet and the air outlet being communicated with the first accommodating space;
a fan disposed in the first accommodating space and opposite to the return air inlet;
an indoor heat exchanger disposed in the first accommodating space and located at a side of the fan proximate to the air outlet;
a piping box disposed in the first accommodating space and proximate to the air outlet;
a nano water ion generating device disposed in the first accommodating space and located at a position of the first housing proximate to the air outlet;
the nano water ion generating device being configured to generate nano water ions with negative charges and hydroxyl radicals generated by ionized water;
the nano water ion generating device including a nano water ion outlet;
and the nano water ion generating device and the piping box being communicated through a vent therebetween;
and
