Space between outer wall 418 and the midfeather 419 has formed the 1st foreign matter storage chamber 416, and the space between midfeather 419 and the inwall 420 has formed the 2nd foreign matter storage chamber 417, and the inner space of inwall 420 has formed the 1st foreign matter disengagement chamber 423.According to the form of collecting unit of dust 400, the application target in space can be different.
Below, according to the sequence of flow of air, describe for the effect of as above forming structure and action.
At first air flows into the inside of collecting unit of dust 400 by collecting unit of dust side draught inlet 401.Collecting unit of dust side draught inlet 401 joins in the outside and the place ahead support member 170, communicates with the 1st foreign matter disengagement chamber 423 inboard, makes the extraneous air inflow.And the inboard of collecting unit of dust side draught inlet 401 has formed the 1st inflow guide structure 421 that is used for air is guided to the inner peripheral surface direction of the 1st foreign matter disengagement chamber 423.Inflow guide structure 421 is given prominence to the inside at inwall 420 and is formed.
Air is in the process of the inside of the 1st foreign matter disengagement chamber 423 rotation, and foreign matter falls downwards, and clean air is upwards discharged by the perforate of conical strainer 405.
For the dispersion once more of the foreign matter that prevents to fall, be provided with blocking-up portion 404 at the downside of conical strainer 405, as shown in the figure, the diameter of blocking-up portion 404 increases downwards gradually, has stoped the rising of foreign matter, has prevented kicking up of foreign matter.And certain spacing being provided with of being separated by below blocking-up portion 404 prevents flow plate 403, avoided cyclonic airflow to move and involved the foreign matter of having collected, and stopped the phenomenon that foreign matter is kicked up.
Simultaneously, the cold air by coldplate 601 provides produces water droplet in the inside of the 1st foreign matter storage chamber 416, under the effect of these water droplets, has increased the collection of fine foreign matters, has further suppressed the floating phenomenon of foreign matter.Moreover, owing to increased the collection of fine foreign matters, reduce small foreign matter and be discharged to outside possibility once more, even water-drop evaporation, small foreign matter also can be kept the state of gathering, has reduced the volume of small foreign matter, has prolonged the cycle that empties small foreign matter, and reduced the air flow resistance of small foreign matter, prevented the decline of dust catching efficiency.
The inside of the 1st foreign matter storage chamber 416 below the isolated foreign matter in the inside of the 1st foreign matter disengagement chamber 423 will be stored into.In order to prevent the leakage of stored foreign matter, below the 1st foreign matter storage chamber 415, be provided with the 1st chamber sealing 415.Below the 1st sealing 415, the cold air that produces on the coldplate 601 is fed to the inside of the 1st chamber sealing 415.For cold air that coldplate 601 the is produced inside of passing to the 1st foreign matter storage chamber 416 by the 1st chamber sealing 415 smoothnesses, the material of the 1st chamber sealing 415 can be to use the higher metal materials of thermal conductivity factor such as aluminium.
Simultaneously, the air that flow into separating plate 437 upsides by conical strainer 405 is the state of having removed the bigger foreign matter of volume haply.Therefore, in order to remove the little small foreign matter of volume, also need to carry out whirlwind and flow.
Below, be described in detail for the whirlwind that carries out once more is mobile.
The air that has passed through conical strainer 405 flows into the inside that guide structure 422 flows into several the 2nd foreign matter disengagement chamber 424 by the 2nd.And because the tangential direction of the inner peripheral surface of the 2nd inflow guide structure 422 towards the 2nd foreign matter disengagement chambers 424, the air that therefore flows into the 2nd foreign matter disengagement chamber 424 inside produces whirlwind in the inside in chamber and flows.
Flow by whirlwind in the inside of the 2nd foreign matter disengagement chamber 424 and below the fine foreign matters separated falls, will be saved in the inside of the 2nd foreign matter disengagement chamber 427.For the dispersion once more of the foreign matter that prevents to have fallen, the following side of the 2nd foreign matter disengagement chamber 424 has formed the structure of shrinking.And for the leakage of the foreign matter that prevents to be stored into the 2nd foreign matter disengagement chamber 417 inside, the following side of the 2nd foreign matter disengagement chamber 417 is by 402 sealings of the 2nd chamber sealing.
Flow into the inside of exhaust portion 407 at the air of the inside separating out foreign objects of the 2nd foreign matter disengagement chamber 424 by the suction inlet 425 of exhaust portion side, gather between the interval of exhaust portion 407 and spacer portion 408.The diameter of exhaust portion side draught inlet 425 is less than the internal diameter of the 2nd foreign matter disengagement chamber 424, therefore can further reduce the foreign matter of the 2nd foreign matter disengagement chamber 424 inside and the possibility that air moves to exhaust portion 407 simultaneously.That is, the foreign matter that accumulates in the 2nd foreign matter disengagement chamber 424 inner peripheral surfaces can not pass through 425 outflows of exhaust portion side draught inlet.
As mentioned above, flow through the whirlwind at two places and the air that filters out foreign matter flows into the inside of motors by motor side suction inlet 172.After having passed through motor, be discharged to the back of vacuum cleaner fuselage 100.
On the upper lateral part of spacer portion 408, formed the lid structure of regulation.Specifically, comprising: the 1st lid 410 that forms whole lid structure; Protect the 3rd lid the 412 and the 2nd lid 409 at the place ahead and the rear of the 1st lid 410; The 2nd lid 409 is fixed on the 1st lid plug-in unit 411 that covers on 401.
The 2nd foreign matter storage chamber 417 has the function that as much as possible foreign matter functions that are stored in the inside separation of the 1st disengagement chamber 424 store with the foreign matter that is kept at the 1st foreign matter storage chamber 416 inside is no longer moved accurately simultaneously.Below, be described in detail for each composition of this function and the 2nd foreign matter storage chamber 417.
With reference to Fig. 7 as can be known, the 2nd foreign matter storage chamber 417 has extended to the below of control of dust main body 406.Specifically, the upside of the 2nd foreign matter storage chamber 417 forms arc-shaped structure according to the position that is provided with of the 2nd foreign matter disengagement chamber 424, and extends downwards.And, formed the once storage portion 446 that at first preserves the 2nd foreign matter disengagement chamber 424 isolated foreign matters on four parts of extending downwards.Once storage portion 446 is in order to ensure bigger storage area, and for the foreign matter of the inside rotation that is collected in the 1st foreign matter storage chamber 416, preferably is provided with more than two.
For the landing that makes the foreign matter smoothness of separating and collect in the once storage portion 446 in the inside of the 2nd foreign matter disengagement chamber 424, the tilted angle of regulation of the 1st inclined plane 440.The 1st inclined plane 440 is not provided with horizontal structure for all are guided to once storage portion 446 sides at the 2nd foreign matter disengagement chamber 424 inner foreign matters that separate in the zone of broad.And, further formed 2nd inclined plane 442 of inclined degree on the part of extension downwards greater than the 1st inclined plane 440 on the 1st inclined plane 440.Certainly, the inner space on the 2nd inclined plane 442 is formed on the once storage portion 446 of the disposable collection foreign matter in inside of the 2nd foreign matter storage chamber 417.
In the drawings, once storage portion 446 is set in qually spaced in four parts, but this is also unrestricted, and more quantity can be set.
Simultaneously, play in the effect of the once storage portion 446 of inner space collection foreign matter on the 2nd inclined plane 442, and outer wall plays the foreign matter that fixedly is collected in the 1st foreign matter storage chamber 416 inside, avoids the effect of its fixed part that shakes.Once storage portion 446 adopts circular mount structure, be arranged on the area of broad, even thereby have elongated foreign matter such as hair to be tangled, utilize user's lower pulling force to remove rapidly.Certainly, the 2nd inclined plane 442 is owing to have certain angle of inclination, and the user can spur downwards flexibly, and removes foreign matter.
Because the bottom on the 2nd inclined plane 442 has extended to the inner face of the 2nd chamber sealing 402, therefore being collected in once storage portion 446 inner foreign matters not only can not break away from the 1st foreign matter storage chamber 416 inside, air can not take place each other yet flow.
The vertical cross-sectional of the vacuum cleaner that provides below in conjunction with Fig. 8, i.e. the cutaway view of the II-II` of Fig. 2 part describes the course of action and the effect of whole vacuum cleaner fuselage 100 in detail with the course of action of collecting unit of dust 400.
With reference to Fig. 8, at first the course of action that vacuum cleaner of the present invention is described with the inflow and the outflow path of foreign matter is as follows.
Extraneous air flows into the inside of vacuum cleaner 100 by the fuselage side draught inlet 171 that is connected with connector 6, and flows into the inside of collecting unit of dust 400 by collecting unit of dust suction inlet 401.Then, in the inside of collecting unit of dust 400,, after having removed foreign matter, flow into the inside of electric machine stand 300 by motor side suction inlet 172 as action described above and effect.
At this moment, electric machine stand 300 is in the state of vertical stand-up, and inflow entrance is towards the top.Therefore, the flow direction by collecting unit of dust 400 horizontal leaked-in airs will change, and be folded to the below and flow.Then, after having passed through electric machine stand 300, be discharged to the outside by the fuselage exhaust outlet 302 on vacuum cleaner fuselage 100 back sides.
Below, describe for the collection process that increases foreign matter.Electrothermal module 610 connects after the power supplys, goes up for the 1st of the electrothermal module 610 relative with coldplate 601 and produces the heat absorption phenomenon, cooling coldplate 601.And, on the 2nd of the 1st opposition side, producing exothermic phenomenon, heat is discharged to the outside by heat unit 602.
The cold air that coldplate 601 is transmitted is delivered to the inside of the 1st foreign matter storage chamber 416 by the 1st chamber sealing 415, forms water droplet on the internal face of the 1st foreign matter storage chamber 416.Because foreign matter will adhere on the water droplet, so foreign matter is that the center is assembled gradually and increased with the water droplet.Then, adjust size and the generation that air conditioning quantity can be controlled water droplet by the effect of adjusting electrothermal module 610.
Because the adhesion of water droplet, above the foreign matter that flows into the 1st foreign matter storage chamber 416 inside will continuously stick on, the collection that increases foreign matter thus.
The generation of cold air and transmission are continuous carrying out in the operation process of vacuum cleaner, and the collection that increases foreign matter will be carried out continuously.After the running of vacuum cleaner finishes, make the sense of current on the electrothermal module 610 opposite, make coldplate 601, promote the evaporation of moisture as heat liberation board work, originally be that the foreign matter that the center gathering increases will form block structure, be collected in the inside of the 1st foreign matter storage chamber 416 with the water droplet.Certainly, if do not change the drive manner of electrothermal module 610, then rely on the outside heat that transmits to carry out natural evaporation fully.
By above-mentioned effect, the foreign matter of the 1st foreign matter storage chamber 416 inside will increase, owing to increased density, occupy very little volume in the inside of foreign matter storage chamber with high-density state.Therefore, because the volume of foreign matter reduces,, increased aesthetic property so inner foreign matter can not float.And, also having suppressed the discharge once more of the foreign matter collected, the foreign matter of having avoided having collected influences air and flows, and has increased the foreign matter dust catching efficiency.Owing to increased the density of foreign matter, also had the prolongation foreign matter advantage in discarded cycle.
