This invention provides an indoor unit, an air conditioner, and a control method for the indoor unit. The indoor unit includes a body and an ion generator. The body has a first side and a second side facing each other. The first side has a first air vent, and the second side has a second air vent. Both the first and second air vents can be opened and closed. The body has an air duct connecting the first and second air vents. The indoor unit has a first state and a second state. In the first state, the first air vent is open for air intake, and the second air vent is closed. In the second state, the second air vent is open for air intake, and the first air vent is closed. According to the technical solution of this invention, by controlling the indoor unit to switch between the first and second states, the indoor unit can continuously run for sterilization, ensuring more thorough purification. This solves the technical problem in the prior art where the indoor side air outlet is closed for a long time during sterilization, causing shutdown protection and resulting in insufficient cleaning time and incomplete cleaning in some areas.

This invention provides a high-pressure filtration device for sealing ring rubber melt, comprising: a machine base; a conveying assembly disposed on the machine base, the conveying assembly including a conveying pipe for conveying the rubber melt; and a filtering assembly including a filter plate inserted on the conveying pipe, the filter plate being provided with at least two sets of filter screens for filtering impurities. This invention, through the cooperation of a first driving assembly and two sets of filter screens, achieves parallel operation of working and cleaning, avoiding the inefficiency of traditional equipment requiring machine shutdown for filter screen replacement.
