  • Patent number: 7419523
    Abstract: This invention relates to a device for a vacuum cleaner comprising a cyclone chamber (10) and a collecting container (21) arranged in association with the cyclone chamber for particles separated by the cyclone. The cyclone chamber comprises an inlet (14) for dust laden air, a particle outlet (17) for particles separated by the cyclone and on outlet (15) for cleaned air. The lastmentioned outled is connected to a vacuum source and the particle outlet (15) for cleaned air. The lastmentioned outled is connected to a vacuum source and the particle outlet (17) is via a tube (18) ending in the collecting container (21). The collecting container comprises a dust bag (37) for collecting the dust particles which is a part of a continuous tube (31) of non air pervious material intended to create several bags. The invention also relates to a cassette intended to be used at the device.

  • Patent number: 6874333
    Abstract: At a refrigerator or freezer cabinet (10) with a space for storing goods, an evaporator (38) extends along the rear wall (18) of the cabinet and confines in sidewards direction a chamber (52), which is also confined by the rear wall (18) and an intermediate wall (44) arranged in front of the rear wall. An opening (54) is arranged in the intermediate wall (44), through which opening an impeller (56) sucks in air from the space and blows the air out into the chamber (52), the cross sectional area of which decreasing in vertical direction so that the air is evenly distributed along the evaporator (38) before the air in sidewards direction passes through the evaporator out into the space along the rear wall, from where the air circulates further on through the space between shelves located therein back to the opening (54).
