The present invention relates to a support element (2) for holding a fan (1), in particular an axial fan, comprising a wall ring (4) for receiving the fan (1). The wall ring (4) has on its outer periphery a hinge (20) consisting of a first hinge part (22) that is connected to the wall ring (4) and a second hinge part (24) that can be pivoted about a hinge axis (X) relative to the first hinge part (22). The invention further relates to a fan (1) comprising such a support element (2).

A fan includes a motor part, an impeller fixed to the motor part, a housing, and a first circuit board mounted with electronic components. The motor part includes an armature having coils, and a second circuit board connected to the coils and the first circuit board. The housing surrounds outer peripheries of the motor part and the impeller. The housing includes an intake port which is an upper opening of the housing, an exhaust port which is a lower opening of the housing, a flange portion enlarged radially outward from an outer circumferential surface of the housing, and a circuit board fixing portion protruding from the outer circumferential surface and making contact with the first circuit board. The first circuit board is disposed spaced apart from the outer circumferential surface, positioned radially inward of a radial outer edge of the flange portion, and arranged to extend in an axial direction.

Axial flow fan

The present invention relates to a wall ring for receiving in particular an axial fan, comprising an annular body with a flow inlet opening and a flow outlet opening and a central longitudinal axis X-X as well as an annular wall extending between both openings. The annular wall has a cavity which is enclosed by an outer wall and an inner wall, in which an electrical heating element may be secured at least over a partial area of the periphery of the annular wall. The annular body consists of at least two partial bodies which are formed by a division of the annular body in a separating plane that extends perpendicular to its longitudinal axis and are detachably connected to one another.

Embodiments of the invention provide a system and method for a backup sump pump kit. The kit is for use with a battery and an alternating current power source. The kit can be adapted to be a portable power source for an external electric device. The kit can include a portable case, a battery-operated back-up sump pump removably stored in the portable case, and a control charger integrated into the portable case. The control charger can include a battery chargers cables, a power input socket to charge the battery, and a power output socket to provide power from the battery to the external electric device. The portable case can include a handle and wheels.

The invention provides a casing, equipment unit, fan unit and electronic equipment capable of easily implementing assembling, disassembling, attaching and so forth without using fixture components, tools, and so forth. The structure is made up of casing sections, hinge parts and a coupling part. The casing sections are made up of not less than two sections and enclosing a hosing space, and members for securing the housing space thereby. The hinge parts are members coupled with the casing sections and supporting each casing section. That is, not less than two casing sections couple the edge parts of each casing section, and bendably support each casing section. The coupling part is a member for restraining the casing sections positionally and maintaining and fixing the housing space. That is, the coupling parts detachably couple each casing section to hold the housing space on each casing section.
