Description
Technical field
The present invention relates to a kind of walking cleaning machine.
Background technology
Disclose a kind of scavenging machine by DE 19531327A1, it has bristle cylinder and disk hairbrush.This disk hairbrush is by drive unit drives.This scavenging machine has the getter device that has motor in addition, and it takes air away from disposal box.Owing to there are two motors that are used for disk hairbrush and getter device, this scavenging machine is compared heavy and is had complicated structure.
Summary of the invention
Task of the present invention is, a kind of scavenging machine is provided, and it has simple structure and less weight.
This task is finished by such walking cleaning machine, this walking cleaning machine has at least one purging roller and has and is used for driving rotatably described purging roller, air-cooled driving motor (Antriebsmotor), and wherein said driving motor has driving shaft, at least one carries the draught fan impeller of cooling air for driving motor this drive shaft, wherein said scavenging machine has dust storage chamber, cleaning material is transported to this dust storage chamber the inside by purging roller, and the suction side of wherein said draught fan impeller is connected with the working region of scavenging machine, thereby at least a portion cooling blast that drives motor aspirates from the working region of scavenging machine.
Aspirate from the working region of scavenging machine by at least a portion cooling blast that drives motor, the dust that has reduced scavenging machine generates.Originally must carry cooling blast because drive motor, thereby not need the device and the driving arrangement that add.Just utilizing the original draught fan impeller that exists to reduce dust generates.Scavenging machine has simple structure and less weight thus.
Draught fan impeller advantageously is connected with the working region of scavenging machine by dust storage chamber.Can realize driving the cramped construction of motor and dust storage chamber thus.The cooling blast support is transported to cleaning material in the dust storage chamber.For fear of driving excessively making dirty of motor, and avoid cleaning material to leak into the environment, be connected in (Stroemungsverbindung) with the circulation of the suction side of draught fan impeller in the working region and be furnished with strainer from driving motor.This strainer is arranged in the outlet that cooling air comes out from dust storage chamber especially.This strainer is arranged on the upper side of dust storage chamber especially at this, thereby is filtered cleaning material that device stops owing to gravity falls back in the dust storage chamber.Reduced the cleaning cost of strainer thus.
It is suitable that the suction side of draught fan impeller is connected with dust storage chamber by cooling air channels.Drive engine arrangement in motor body.Cooling air channels especially is configured on the tube connector that connects dust storage chamber and motor body.This tube connector not only forms mechanical connection between motor body and the dust storage chamber at this, and forms circulation and connect.Dust storage chamber especially is configured in the disposal box, and wherein this disposal box advantageously removably is fixed on the scavenging machine.This disposal box can carry out emptying and cleaning in simple mode thus.Can stipulate that also cooling air channels is configured on the disposal box.Cooling air channels especially is integrally molded on the disposal box, thereby cooling air channels is not needed the member that adds.Simplified the manufacturing of scavenging machine thus.Driving engine arrangement is favourable above disposal box.But also can stipulate, drive motor is arranged in disposal box on direct of travel back.Can realize low scavenging machine structure height thus, this makes and also can clean below obstruction.
Scavenging machine advantageously has two purging rollers, and they drive by driving the mutual incorgruous ground of motor (gegenlaeufig), and drive on the ground toward each other.Purging roller meets the destination with cleaning material and is conveyed into dust storage chamber according to cape principle (Ueberwurfprinzip).Verified, when carrying cleaning material, can realize extraordinary cleaning result according to the cape principle.It can not only absorb little dust part, and can absorb thicker dirt, as box, jar or similar item.
Generate in order to reduce dust preferably, can stipulate that all cooling blasts that drive motor all aspirate from the working region of scavenging machine.But also can stipulate, can adjust by the share of the cooling blast of the working region of scavenging machine suction.The suction of cooling air can flexibly be matched with corresponding demand by the operator thus.
Drive motor advantageously internal combustion engine, the wherein bent axle of driving shaft internal combustion engine.This internal combustion engine especially has cylinder, and this cylinder has fin.Advantageously be provided with draught fan impeller, be used for carrying cooling air to the fin of cylinder of internal combustion engine.The conveying of cooling air is necessary for internal combustion engine especially.Draught fan impeller originally exists in internal combustion engine, thereby does not need the member that adds.
But can stipulate also that the driving motor is the motor by the battery supplied energy.But at this battery battery of recharge particularly.Advantageously, battery arrangement is in the cooling blast of being carried by draught fan impeller.The power of battery, particularly battery is at low temperatures obviously than higher under higher temperature.Cooling by battery can realize tangible power ascension thus.By with battery arrangement in the cooling blast that will carry after all by draught fan impeller, do not need to be used for the attachment device of battery cooling yet.Have only battery arrangement in cooling blast, and motor not cooling off, also is favourable.
