Embodiment
In conjunction with Fig. 1 to Fig. 4, the utility model is described in further detail.
A kind of used for range hood can electric heating oil removing wind wheel structure, comprise the wind wheel 1 and the motor 2 that are installed in range hood volute inside, described wind wheel 1 is comprised of the wheel hub 11 of both sides and the blade 12 being fixedly connected between two wheel hubs, on described motor 2, be equiped with rotor brush 21 and stator brush 22, described in two, on wheel hub 11, be all equiped with a conductive hoop 3, on blade 12, be evenly laid with one deck conductive heating layer 4, described in two, conductive hoop 3 all fully contacts with conductive heating layer 4, and rotor brush 21, at least one conductive hoop 3 and stator brush 22 are electrically connected in external circuit by wire.Described conductive hoop 3 is the conductive homogeneous metal ring with wheel hub 11 form fit of wind wheel.Described conductive heating layer 4 for be evenly coated on blade 12 can conductive heater formula coating 42.This coating can be can conduct electricity and by the metallic coating of current heating, also can be the novel high polymer coating that can conduct electricity and generate heat, and it can be by mode moulding such as spraying, showering or plating.Described heating temperature that can conductive heater formula coating 42 is higher than the melting point of grease.Thereby though heating temperature also can accumulate heating heat by long fever time a little less than grease temperature, grease is melted, the speed of melting removing when heating temperature during higher than grease melting point can improve greatly.Described blade 12 top layers are also coated with the first isolation layer 41 and the second isolation layer 43, described can conductive heater formula coating 42 between this first isolation layer 41 and the second isolation layer 43.The setting of the first isolation layer 41 is that the setting of the second isolation layer 43 is between wind wheel body and range hood body, to form short circuit for preventing in order to prevent wind wheel body and can form short circuit between conductive heater formula coating 42.Can by the modes such as spraying, showering, plating apply successively the first isolation layer 41, can conductive heater formula coating 42 and the second isolation layer 43.Described conductive hoop 3 is electrically connected by wire with rotor brush 21, and stator brush 42 is electrically connected in external circuit by wire.
First on blade 11 surfaces of wind wheel 1, by modes such as spraying or showerings, apply one deck and there is certain thickness the first isolation layer 41; And then by modes such as spraying or showering or plating, on moulding the first isolation layer 41 of parching, apply one deck can conductive heater formula coating 42, this can conductive heater formula coating can be the metallic coating that can conduct electricity and pass through electric current self-heating, also can be the novel high polymer coating that can conduct electricity and generate heat, this coating is consistent and even at coating required thickness, and wherein the setting of the first isolation layer 41 is for avoiding wind wheel body and can forming short circuit between conductive heater formula coating 42.Then on the wheel hub 11 of wind wheel 1 both sides, install respectively a conductive hoop 3, this conductive hoop 3 is the conductive homogeneous metal ring with wheel hub 11 form fit, during installation, to guarantee conductive hoop 3 and can conductive heater formula coating 42 fully contact, and because even thickness that can conductive heater formula coating 42 is consistent, the electric current of therefore flowing through in coating is consistent, thereby makes the heating value on same time intra vane consistent.After installing conductive hoop 3, can on conductive hoop 3, connect and establish wire, then can conductive heater formula coating 42, all again apply certain thickness the second isolation layer 43 on conductive hoop 3 and wire, to avoid forming short circuit between wind wheel body and range hood body.By connecing the wire of establishing on conductive hoop 3, be communicated with the rotor brush 21 that is fixed on motor 2, then adopt another wire that the stator brush 22 of motor 2 is communicated with external circuit, so just the wind wheel with can conductive heater formula coating is connected in to external circuit and has suffered.
When in running order, electric current passes to rotor brush 21 by stator brush 22, and then there is this rotor brush 21 to pass to conductive hoop 3, due to conductive hoop 3 with can conductive heater formula coating 42 fully contact, so electric current is through this coating produce heat energy, by the heat energy heating of this generation, is attached to the grease on blade 12, make its softening even thawing be liquid, then the centrifugal force that utilizes wind wheel 1 rotation to produce, makes this liquid grease depart from wind wheel blade, reaches the effect of clean wind wheel.
