Fig. 6 be among Fig. 3 I-I ' to cutaway view.Below with reference to Fig. 6 the internal structure and the course of work thereof of dust collect plant 400 are elaborated.
As shown in Figure 6, dust collect plant 400 provided by the invention comprises: control of dust body 406; The case sealing 402,415 that can selectivity seals up control of dust body 406 downsides; Be installed in the inside of control of dust body 406, can improve the conical strainer 405 of dust catching efficiency; Can prevent the blocking-up portion 404 of the scattering foreign matter that deposits; Can slow down the flow velocity of cyclonic air flow, foreign matter be sunk, and can prevent the anti-flow plate 403 that dust floats; Be arranged on the upside of control of dust body 406, can make the mobile exhaust portion 407 smoothly of air of discharging from control of dust body 406; The air that can make the exhaust portion 407 of flowing through is along the mobile spacer portion 408 of a certain direction; With the cap assemblies 409,410,411,412 that is arranged on exhaust portion 407 upsides.
Describe the formation of control of dust body 406 below in detail.
Described control of dust body 406 is provided with a plurality of walls that vertically extend and form, and comprises being arranged on outermost outer wall 418; Be positioned at the midfeather 419 of outer wall 418 inboards; With the inwall 420 that is positioned at midfeather 419 inboards.Described midfeather 419 and inwall 420 are not arranged in the zone that dust collect plant air entry 401 occupies, and can make flowing of air more smooth and easy thus.
Space between described outer wall 418 and the midfeather 419 constitutes the first foreign matter storage bin 416; Space between midfeather 419 and the inwall 420 constitutes the second foreign matter storage bin 417, and the inner space of inwall 420 then constitutes the first foreign matter separator box 423.But, the concrete user mode of dust collect plant 400 not simultaneously, the purposes in these spaces is difference to some extent.
Being benchmark with the sequence of flow of air below is elaborated to the effect and the course of work of above-mentioned parts.At first, air is by the inside of dust collect plant air entry 401 inflow dust collection devices 400.Wherein, the outside of dust collect plant air entry 401 contacts with front end support 170, and its inboard then is connected with the first foreign matter separator box 423, extraneous air can be sucked thus.In the inboard of dust collect plant air entry 401, from inwall 420 to the inside direction protrude and to be formed with first and to flow into guide part 421, thereby air can be guided into the inner peripheral surface of the first foreign matter separator box 423.
The air that enters the first foreign matter separator box, 423 inside can make foreign matter sink in the process that is rotated, and the air that is purified is then upwards discharged by the perforate of conical strainer 405.Using the reason of conical strainer 405 at this is because dust collect plant air entry 401 is positioned at upside, therefore can produce the cyclonic air flow of fair speed on the top of conical strainer 405, and produces the cyclonic air flow than low velocity in its underpart.Promptly, foreign matter can be rotated on the position in the more close outside in the cyclonic air flow of fair speed, foreign matter then can be rotated near inboard position in than the cyclonic air flow of low velocity, therefore in order to remove foreign matter more effectively, preferably filter is designed to cone shape.
Described conical strainer 405 is installed in the centre of demarcation strip 437, and demarcation strip 437 then constitutes the upper wall of the first foreign matter separator box 423.Conical strainer 405 also can be designed to be able to the structure that disassembles from demarcation strip 437, and is formed with a plurality of perforates on it, thereby extraneous air can pass perforate to its inner inflow.
At this, for the foreign matter that prevents to fall disperses once more, be provided with blocking-up portion 404 at the downside of conical strainer 405, as shown in Figure 6, more down its diameter is big more in described blocking-up portion 404, so just can prevent that foreign matter from dispersing once more.The below of blocking-up portion 404 is formed with the anti-flow plate 403 of an apart determining deviation, and it can prevent that the foreign matter that deposited is under the influence of cyclonic air flow and the phenomenon of floating once more.
In addition, isolated foreign matter will be stored into the first foreign matter storage bin 416 that is positioned at below it in the first foreign matter separator box 423.At this,, be provided with first case sealing 415 in the lower end of the first foreign matter storage bin 416 for leaking appears in the foreign matter that prevents to store.
In addition, isolated bigger foreign matter to demarcation strip 437 upside leaked-in airs, but also needed to utilize once more cyclonic air flow to isolate small foreign body by conical strainer 405.Below back one process is elaborated.
The air of described conical strainer 405 of flowing through will flow into the inside that guide part 422 flow into a plurality of second foreign matter separator boxs 424 by second.In addition, because the second inflow guide part 422 is tangential on the inner peripheral surface of the second foreign matter separator box 424, the air portion's generation within it that therefore flows into the second foreign matter separator box 424 rotatablely moves.
The isolated foreign matter of inner utilization cyclonic air flow at the second foreign matter separator box 424 will fall to the bottom, and be stored in the second foreign matter storage bin 417.For the foreign matter that prevents to have sunk disperses once more, the diameter of the second foreign matter separator box, 424 downsides dwindles gradually.And, for the foreign matter that prevents to be deposited in the second foreign matter storage bin 417 leakage occurs and is provided with second case sealing 402 at its downside.
At this, described second case sealing 402 utilizes shaft-like attaching parts to be connected with first case sealing 415, its objective is the internal capacity that increases the first foreign matter storage bin 416.In other words, owing to need in the space between the upper end of first case sealing 415, store more foreign matter as far as possible, preferably use the less rod-like members that takes up space that both are interconnected in the lower end of second case sealing 402.
To flow into the inside of exhaust portion 407 through air entry 425 after the air separation that enters the second foreign matter separator box, 424 inside goes out foreign matter, and accumulate in the space between exhaust portion 407 and the spacer portion 408.At this, the diameter of air entry 425 is less than the internal diameter of the second foreign matter separator box 424, can obviously reduce the possibility that the second foreign matter separator box, 424 interior foreign matters flow to exhaust portion 407 like this.In other words, the foreign matter that is deposited on the second foreign matter separator box, 424 inside can not pass through air entry 425 outflows.
But because the diameter of the exhaust portion side draught gas port 425 and the second foreign matter separator box 424 is poor, produce air at a high speed simultaneously in the inside of exhaust portion side draught gas port 425 mobile and turbulent.For the described air of rectification flows, in the inside of exhaust portion side draught gas port 425, with the pipeline of exhaust portion side draught gas port 425 integrally formed rectification part 463.As shown in the figure, described rectification part 463 is a cross shape.But the shape of rectification part 463 is not limited thereto, and also multiple shapes such as in-line or radiation can be arranged.We elaborate in the back again to the working condition of rectification part 463.
As mentioned above, will be through the air that two place's cyclonic air flows purify by motor air entry 172 flow direction motors, then, the air of the motor of flowing through will be discharged from the rear of vacuum cleaner body 100.
In addition, the upside of spacer portion 408 also is provided with cap assemblies.Specifically, described cap assemblies comprises: constitute first lid 410 that covers agent structure; Be separately positioned on the 3rd lid 412 and second lid 409 at first lid 410 front portions and rear portion; With first lid 410 and second can be covered the 409 lid plug-in units 411 that are fixed together.
Fig. 7 is Fig. 5 " A " portion enlarged drawing, and Fig. 8 is Fig. 6 " B " portion enlarged drawing.
As shown in Figures 7 and 8, expression has second separator box 424 and is inserted into the exhaust portion side draught gas port 425 of described second separator box 424 inside with certain depth on the accompanying drawing.Have certain intervals between the outer peripheral face of the inner peripheral surface of described second separator box 424 and described exhaust portion side draught gas port 425, therefore its flow velocity of air of discharging by exhaust portion side draught gas port 425 can become greatly more, therefore can improve the removal efficient of foreign matter.
Just, the diameter of described exhaust portion side draught gas port 425 is more little, and the air velocity of the exhaust portion of flowing through side draught gas port 425 inside and turbulent flow can become big more, meanwhile can produce bigger noise.Reduce noise in order to eliminate the mobile turbulent phenomenon of described air, be formed with the rectification part 463 of cross shape in the inside of described exhaust portion side draught gas port 425, therefore can fully eliminate the turbulent composition of the air of described exhaust portion side draught gas port 425 inside of flowing through.
As mentioned above, eliminate turbulent composition after, noise also will reduce.
In the present embodiment, rectification part 463 its end faces are cross shape, and prolong back formation rectification part 463 along the vertical direction, and in shape above-mentioned but rectification part 463 is not confined to, it can have multiple other shapes such as in-line shape or radiation shape.The quantity of plate that constitutes rectification part 463 in addition is many more, can improve the effect that reduces high frequency noise more.
Effect to the reduction noise is as follows from the another side.Promptly owing to reduced the turbulent energy that air flows by rectification part 463, so noise is also with regard to corresponding reduction.
Fig. 9 is the noise comparison diagram that the rectification part front and back are set.The lines that are shown on Fig. 9 are under all identical situation of other conditions, the different experimental result according to whether rectification part 463 is set.The cross that is shaped as in this rectification part 463.
As shown in Figure 9, lines 1 (478) are the level of noise lines that is provided with before the rectification part 463, and lines 2 (479) are the level of noise lines that is provided with after the rectification part 463.Shown in lines, rectification part 463 back high frequency noises are set as can be seen have been lowered.
Figure 10 is a vacuum cleaner body vertical structure cutaway view provided by the invention.Below with reference to Figure 10 the course of work of dust collect plant 400 and vacuum cleaner body 100 is elaborated.
As shown in figure 10, at first extraneous air enters the inside of vacuum cleaner body 100 by the body air entry 171 that is connected with connector 6, and the inside by dust collect plant air entry 401 inflow dust collection devices 400, the cleaned air behind the separating out foreign objects of the inside of dust collect plant 400 will be by the inside of motor air entry 172 inflow motor frames 300.
At this moment, because motor frame 300 vertically is provided with, therefore its inflow entrance is towards the top,, the air of flowing through behind the dust collect plant 400 will vertically bend the inside that the back flows into motor frame 300 downwards, discharge to the outside by the body exhaust outlet 302 that is positioned at vacuum cleaner body 100 back sides at last.
Can be reduced in the high frequency noise that produces in the dust collect plant of vacuum cleaner according to aforesaid the present invention.
Preceding described, the end surface shape of rectification part 463 is not limited to cross shape in the present embodiment, and it can have in-line shape or the radiation shape that prolongs to different directions or the lattice shape that forms with a plurality of polygons, toroidal, elliptical shape etc. from central division.
In addition, the shape that described in the present embodiment rectification part 463 prolongs along the vertical direction with its end face constitutes, but also is not limited thereto, and it can be constitute from top to bottom spiral-shaped or the multiple shape that is bent.If just the structure of rectification part 463 is complicated more, its difficulty of processing is just big more, and the resistance to air is also big more simultaneously, therefore is difficult for taking.So in the resistance to air is not clearly scope, multiple other distortion can not arranged.
In addition, described in the present embodiment rectification part 463 is arranged on the end of exhaust portion side draught gas port 425, but it is provided with the position and also is not limited thereto, and also same effect can be arranged as long as be arranged on the pipeline inside of exhaust portion side draught gas port 425.As long as therefore described rectification part 463 is arranged on the inside of exhaust portion side draught gas port 425.
In addition, the degree of depth of described rectification part 463 also has different values according to the difference of dust collect plant.The degree of depth of the big more rectification part of the flow velocity of described air is that lower-upper length is also long more.
In addition, described in the present embodiment rectification part 463 is arranged on the inside of exhaust portion side draught gas port 425, but can not exist according to the described sometimes exhaust portion side draught of the structure difference gas port 425 of dust collect plant.At this moment, described rectification part 463 can be set directly at the inside of second separator box 424, reduce the mobile noise of air with this.
