    摘要: At least three axis direction through-holes arranged at equal intervals in the circumferential direction are provided in a rotor laminated steel plate and a rotor end plate. The rotor laminated steel plate and the rotor end plate are fixed with three rivets for passing through the axis direction through-holes. A balance weight formed of one laminated metal plate is fixed to the one rotor end plate with two rivets of the three rivets. A balance weight formed of the other laminated metal plate is integrated by caulking and has a projection formed thereon and fixed to the other rotor end plate with the remaining single rivet. The projection is engaged with a recess or a through-hole provided in the other rotor end plate so that the balance weight is positioned to the other rotor end plate.

    摘要: There is provided an electric dust collection device which can effectively capture fine particles while avoiding a pressure loss. The electric dust collection device is provided with a charging electrode, a dust collection electrode, and a repulsive electrode. Along a flowing direction of an airflow, the dust collection electrode is disposed downstream of the charging electrode, and the repulsive electrode is disposed downstream of the dust collection electrode. The dust collection electrode is formed of a conductive material which partitions a ventilation passage through the airflow pass in the flowing direction. The repulsive electrode forms an electric barrier which has the same polarity as that of the charging electrode with a posture that intersects the airflow in the flowing direction.

    摘要: There is provided an air conditioner with sufficient thermal insulation performance without affecting the installation property in installing an air conditioner in a casing. The air conditioner includes an indoor unit having an indoor heat exchanger, an outdoor unit having an outdoor heat exchanger connected to the indoor heat exchanger through a refrigerant pipe, and an outside casing housing at least the outdoor unit and is attached to a building wall that partitions an outdoor space and an indoor space. The outside casing is fitted in a wall communication hole and has an inside space in which the outdoor unit is capable of being disposed, the wall communication hole being formed in the building wall and communicating between the outdoor space and the indoor space. The inside space is opened to the outdoor space. The outdoor unit is disposed in the inside space of the outside casing. A thermal insulation material is disposed in the inside space of the outside casing, and the thermal insulation material at least includes a first thermal insulation portion that is disposed on a side of the outdoor space and a second thermal insulation portion that is disposed on a side of the indoor space and is attachable and detachable.

    摘要: A hermetic type compressor (1) includes a compressor main body container (10) that is a vertical type having a cylindrical shape, and that is provided with a discharge pipe (107) and a suction pipe (104) for a refrigerant, an accumulator container (25) that is connected to the suction pipe (104), a compression section (12) that is arranged inside the compressor main body container (10), that compresses the refrigerant, which has been sucked from the accumulator container (25) by way of the suction pipe (104), and that discharges the compressed refrigerant from the discharge pipe (107), and a motor (11) that is arranged inside the compressor main body container (10) and that drives the compression section (12). The accumulator container (25) includes an accumulator shell (26) having a cup shape, and in which an opening side (28b) of the accumulator shell (26) is bonded to the compressor main body container (10). A partition member (28), which partitions an interior portion of the accumulator shell (26), is provided in the interior portion, and a thermal insulation section (35), which includes an interior portion space (35a) having a hollow structure that blocks a heat transfer from the compressor main body container (10) to the accumulator container (25), is formed between the partition member (28) and a bottom shell (26) that is included in the compressor main body container (10).

    摘要: A compressor main body container includes a main shell having a vertical cylindrical shape, a top shell having a cup shape, and a bottom shell having a cup shape, and an interior portion of the main shell is hermetically sealed by securing an opening side of the top shell to an upper end portion of the main shell at a first welded portion by welding, and securing an opening side of the bottom shell to a lower end portion of the main shell at a second welded portion by welding. The accumulator container includes an accumulator shell having a cup shape, and an interior portion of the accumulator shell is hermetically sealed by securing an opening side of the accumulator shell to an opposite opening side of the bottom shell at a third welded portion by welding at a position lower than a position of the second welded portion in the compressor main body container.
