Background technology
Floor brush by DE-U 298 12 377 known described structures.In this known design, suction nozzle shakes pipe joint by means of one and is connected on the air guide channel.Suction nozzle comprises the bristle holder of a band bristle bars that can move both vertically and can handle by floor push, and bristle bars can move in the base plate of suction nozzle by the mouth in floor one side or shift out.When being the carpet dust suction, base plate slides on the ground that will clean.For the floor covering of clean, smooth, bristle bars shifts out by handling floor push.Be connected the suction nozzle that can shake on the air guide channel and adapt to the unevenness on ground, and with the sweep-up pipe orientation independent that is connected on the bend pipe, plane parallel is in the location, ground that will clean all the time.
By DE-A 42 43 244 known a kind of floor brush, it does not have switching mechanism applicable to various ground, both can be used for the carpet dust suction and can be used for the smooth earth dust suction yet.Suction nozzle is guided on roller and the suction inlet section that can shake is arranged, and its plane parallel is in the floor covering location that will clean.The base plate that groove shape passage is arranged that suction inlet Duan Youyi piece is narrow constitutes and is contained in the suction nozzle pivotally.Be provided with one along the dust suction direction in suction inlet section back and abut in ground ground sealing strip all the time.
Suction inlet is adapted to the unevenness on ground in these that introduce design, and locatees with the fixing and directed irrelevant ground that is parallel to that is connected the sweep-up pipe on the bend pipe.This is cleaning floor effectively in principle.Especially the mobile danger that increases greatly that exists suction inlet to be sucked on the ground for the long wool carpet but then and when dust collector motion, must apply.Sucked at opposite extreme situations lower floor suction nozzle and it is to be caused uncomfortable effect of jumping, when this situation occurring, no longer may be cleaned effectively.
There is the floor brush of balanced serviceability must satisfy many different requirements.Suction nozzle (transverse to the dust suction direction) should have enough length, so that can clean big floor area with the least possible amount of exercise.In addition, suction inlet must be designed to admit fiber and small articles, for example clip, paper scrap etc.Appropriate thus is that the part is wide suction hole at least.Also have, floor brush must have and not allow the good dust removal ability that degenerates from suction nozzle central authorities to outward flange.By the moulding and the size of suction inlet, guarantee in whole suction inlet, to form pressure distribution as far as possible uniformly.At last, floor brush must be designed to, and it just can move with less tractional force when dust suction, even and run into the long wool carpet and also can avoid sucking, otherwise no longer may normal operation.
The floor brush of the described structure of preface that adopts in the real work has one to see suction inlet than broad along the dust suction direction, to guarantee to receive fiber and dust well by authoritative theory, especially uniform pressure distribution can also be arranged in suction inlet.In some designs, suction inlet is made of a straight channel that one side is uncovered on ground, and it has the suction limit of arrangement parallel to each other, and the spacing on suction limit is about 20mm in central authorities.In other designs, the width of suction inlet reduces outside the suction nozzle mediad, approximately is reduced to 10mm from 25mm.
By DE-C 199 00 968 for receiving fiber and dust advantageously, suction inlet therein section district design a broad and groove is arranged, it is the boundary with a strut rail that groove has been interrupted along suction inlet limit and the rear side of dust suction direction in the back in inhaling porose area, and what link to each other with strut rail is a dust bag that is equipped with rear portion fibrous wick device.In this design, the cross section that becomes a mandarin of suction inlet one side on ground enlarges markedly.
Known floor brush receive aspect fiber and the dust quite desirable.Yet suction properties is not always so balanced, is to be cost with bigger tractional force because improve the measure of receiving dust and fiber.
Summary of the invention
The objective of the invention is to further develop the ground suction nozzle of the described structure of preface, it can do not change receive fiber and dust well in motion on the layer of shop, the floor of fabric easily, even and on the ground of long wool carpet, can not suck yet.
By the present invention is to reach the measure that this purpose takes to be, order has goes into flow section less than 5000mm above suction inlet one side on the floor of 530mm girth
2Observing by under the situation of limiting value of the present invention, the floor brush that is connected on the floor-type vacuum cleaner common on the market can not be sucked on the layer of the shop, floor of fabric.This floor brush is just movable with little tractional force.Suction inlet can design arbitrarily to a large extent, here must observe by the present invention about going into the limiting value of flow section.
Suction inlet has one to be the stage casing that the boundary comprises a suction hole that is connected with air guide channel with the fibrous wick device, and respectively has one to be the narrow suction channel on boundary with the suction inlet limit in the both sides, stage casing.Within the scope of the invention, suction inlet designs much widelyer than the part of both sides connection in the scope in stage casing.Unexpectedly, if the suction inlet shunt adjacent with the stage casing designs very narrowly, that is the spacing between the suction inlet limit is very little, does not have adverse influence for dust suction.Length for suction nozzle (transverse to the dust suction direction) does not have any restriction yet.In order to observe the flow section of predesignating of going into, if suction nozzle has big length, then suction inlet should design more narrowly.
By a kind of preferred design of the present invention, be arranged in parallel with the suction inlet limit of back in front along the dust suction direction, meanwhile, the distance between the suction inlet limit is less than 16mm, preferably less than 14mm.When the distance between the suction inlet limit is very little, advantageously in the zone of suction channel above the suction inlet limit of the suction inlet that connects in the both sides, stage casing a cross section expansion that helps the suction inlet internal pressure to distribute is arranged.Flowing into the dynamic pressure loss that air in the suction inlet can be low introduces in the suction channel of broad.
By a kind of preferred design of the present invention, suction inlet design in the zone of section therein a broad and groove is arranged, it disconnects along the dust suction direction and inhales limit at that of back inhaling porose area, and the groove rear side is the boundary with the strut rail, is equipped with the dust bag of rear portion fibrous wick device to be connected with strut rail.The partial design that suction inlet is connected in both sides on the stage casing must be narrower, so that observe by the present invention for the limiting value of going into flow section.
