Indoor unit and air-conditioner

Abstract

The invention provides an indoor unit and an air-conditioner. The indoor unit is used in the air-conditioner and comprises a shell, a fan and a filter screen assembly. The filter screen assembly comprises a filter screen, a hairbrush, a first transmission device, a second transmission device and a first drive device. The two ring-shaped ends of the filter screen are arranged on the first transmission device and the second transmission device in a sleeving manner correspondingly. The first drive device drives the first transmission device or the second transmission device to rotate around the self axis to drive the filter screen to rotate around the first transmission device and the second transmission device, and the filter screen covers a wind return opening in the rotating process and / or makes interference contact with the hairbrush. In the working process, the filter screen can cover the wind return opening and has a function of filtering impurities and dust, it is ensured that air entering an air-conditioning room is clean, the hairbrush can clean the dust on the filter screen automatically, and the filter screen does not need to be manually disassembled to be cleaned. An interval is reserved between the hairbrush and the wind return opening, it is effectively ensured that the filter screen assembly does not occupy a wind return channel, and the wind return efficiency is ensured.
