Embodiment
Lift a preferred embodiment below, and come the clearer the present invention that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, gasoline engine generator of the present invention comprises: motor 1, empty filter 2, control panel 3, current inversion system and device 4, stator 5, external rotor 6, fan 7, rear cowl 8, fuel tank 9 and silencing apparatus 10, motor 1 has casing 11 (side cover), bent axle 12, Carburetor 13, antivibration pad 14, starter 15 and handle 16, the stator 5 that in the casing 11 (side cover) of motor 1, connects generator by screw 51 fastening pieces such as grade, Carburetor 13 is connected with control panel 3 with packing ring 32 by screw 31, antivibration pad 14 is locked by screw with casing 11 or is fixedlyed connected, vibrations and noise when antivibration pad 14 reduces generator operation, starter 15 is positioned on casing 11 1 sides, starter 15 is fixedlyed connected with handle 16, and pulling handle 16 got final product when generator started.The fuel tank 9 of gasoline engine generator is positioned at the top of motor 1, and fuel tank 9 end faces are installed one handle 91, make things convenient for carrying of generator, is provided with a gasoline mouth 92 near handle 91, and this gasoline mouth 92 is used for gasoline and imports in fuel tank 9.Silencing apparatus 10 is fixedlyed connected with casing 11 with packing ring 102 by screw 101.
Fan 7 is fixed on the external rotor 6, external rotor 6 shell backs are provided with and fan 7 corresponding overcurrent air ports, the external rotor 6 that fan 7 is housed is the shell-type structure, external rotor 6 can be detained cover stator 5, external rotor 6 is dynamically connected with 12 on the bent axle of motor 1, stator 5 and external rotor 6 are the part of generator, and stator 5 is arranged in external rotor 6, and stator is that the stacked outward flange with plastic packaging of silicon steel is extremely to structure.Stator 5 and external rotor 6 are the coaxial line assembly relation with bent axle 12, arrange with this power transmission that realizes generator, because what stator 5 and external rotor 6 were formed is intermediate frequency external rotor generating body, belong to the generating body of minor axis to size, power transmission is arranged simple, and axially need not too much attached layout, so the overall axial length of generator can be controlled in a less dimensional range.
The casing 11 (side cover) of motor 1 is axial shell cavity configuration; antivibration pad 81 is installed in rear cowl 8 belows; antivibration pad 81 is fixedlyed connected with rear cowl 8 by screw 82; rear cowl 8 is fixedlyed connected by screw 83 with casing 11 and is formed work chamber; work chamber can be to stator 5 and external rotor 6 running protections, and rear cowl 8 also is a dunnage of generator simultaneously.Thus no matter generator axially or radially all can be defined as less bulk, and can fixed generator shaft to the bulk scope of height in arrange generator control panel 3.
As shown in Figure 2, realize that the current inversion system and device 4 of generator power frequency electric power output is installed in the back side of control panel 3, current inversion system and device 4 heat dispersing surfaces are the intake grill of corresponding work chamber inwardly; The position that connects Carburetor on generator control panel 3 is provided with slot 33, empty filter 2 is provided with corresponding projection 21, and projection 21 is transplanted a cutting for strip, after projection 21 is inserted in the slot 33, empty filter 2 patches with control panel 3 and is connected, and forms the integral slab face effect of generator control panel behind the plug-in mounting.Because the current inversion system and device 4 of generator is arranged on the control panel 3, and adopted the empty filter 2 of plug-in type, the supporting essential occupation space of generator function moves on to the appropriate position on the control panel 3, and the generator spatial structure is compactness further.
As accompanying drawing 3 and shown in Figure 4, the silencing apparatus 10 of gasoline engine generator blendes together the type secondary muffler for the multi-cavity chamber impedance of resonant mode, classification noise reduction and sound absorption function are strengthened the noise elimination effect of silencing apparatus, and can obtain little bulk structure, thereby satisfying the compactedness designing requirement of generator. silencing apparatus 10 comprises suction tude 103 and steam outlet pipe 104 etc., and suction tude 103 and steam outlet pipe 104 lay respectively at the both sides of silencing apparatus 10.
As Fig. 1 and shown in Figure 5, when generator operation, the cooling system of gasoline engine generator is an independently system, the cooling system of gasoline engine generator comprises two cooling systems, a cooling system comprises starter 15 and silencing apparatus 10, outside air is sucked by the fan of starter 15, and water conservancy diversion blows to silencing apparatus 10 behind the main heating position of cooling gasoline engine generator again; And the generating body cooling that stator 5 and external rotor 6 are formed is another independently cooling system, and under the driving of fan 7, outside air sucks from the intake grill of work chamber 120, behind the cooling generating body, discharges from the thermovent of rear cowl 8; Under the intake grill air suction effect of work chamber 120, the current inversion system and device 4 that is arranged in control panel 3 back sides also can obtain the heat radiation cooling, and the overall cooling system of generator is formed in three aspects like this.
In sum, the present invention is to use minor axis to arrange the basis to size external rotor generating body as transmission, split the generating output unit of generator, be that the generating body inversion system is loaded on the control panel, and on control panel the empty filter of equipped plug-in type, and adopt the multi-cavity chamber impedance of resonant mode to blend together the type secondary muffler, and strengthen promoting the generator Structure compactedness, be achieved as follows comprehensive advantage after implementing with this:
A, gasoline engine generator compact structure, weight saving, good portability;
B, after control panel was function intensified, complete machine structure was simple, and working service is convenient;
C, the cooling system connection and reasonable arrangement, cooling effect is good;
D realizes that on the basis that reduces the silencing apparatus size noise reduction promotes.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
