Abstract: A vacuum cleaner includes a cleaner body and a dust container separably mounted on the cleaner body. The dust container includes a dust collection body including an opening, a wall, and a dust separation part. A cover covers the opening of the dust collection body. An air guide is disposed at the dust collection body, the air guide having an opening provides an inflow hole through which air separated from dust in the dust separation part is introduced, and a filter accommodated in the air guide filters the air separated from the dust. When the cover uncovers the opening of the dust collection body, the filter is visible through the opening of the air guide.

Abstract: A refrigerator includes a noise reduction device and a machine room that accommodates a condenser and a compressor. The noise reduction device includes a sensing unit configured to measure noise generated from the machine room of the refrigerator and a generating unit configured to output a sound signal having a frequency canceling or reducing the noise. The machine room is defined by a case that has a communication portion configured to communicate a fluid between an inside of the case and an outside of the case to thereby exchange heat between the fluid and the condenser and between the fluid and the compressor.
