By in the explanation of the present invention, the carpet device is so-called standard type carpet.That class carpet described in No. 312 publications of international electrical engineering standard meeting (IEC) (second edition 1981) " vacuum cleaner technical committee " (August 31, Showa58 (1983)) that the standard type carpet is just published in the Japanese power industry association by as the cooperation legal person described in the 51st page of the ancillary documents A.
In other words, press IEC-SC59F (Secretariat) 26, " a kind of method of measuring vacuum cleaner " annex A, chapters and sections A, 1.1.2 meets following condition and weight by the carpet that is adopted in the embodiments of the invention.In other words, this kind Hui Erdun (Wilton) carpet is a kind of all woolen type Wilton carpet, the high 6-7mm of plot blanket, and weight is 1.40-1.55kg/m
2, it is that a kind of carpet and wire harness number of tool V-shaped line bundle is 140,000-175,000/m
2, this carpet that is used for testing also has regulation (a kind of fiber carpet) at the JIS-L-4404 of Japanese Industrial Standards (JIS).
Moreover " floor " means it is timber floor, in any case but will mention " matting " especially also can be used.The floor of touching upon can be consulted the standard floor described in the appendix A of mentioning in the above.
Moreover in pressing explanation of the present invention, " impeller " directly produces torque (revolving force), the most handy metal material of impeller (aluminium) or being made of one of plastic resin injected plastics material structure by means of clashing into mutually with the air-flow with directionality.
In other words, the ratio of rigidity brush element of wheel blade portion (brush element and the common name of scraping plate) is big, and in addition as a kind of basic conception, brush element comprises spongiform material, and flight portion is scraped plate or by scraping constituting of plate and brush element by simple.The above-mentioned flight portion of ratio of rigidity of scraping plate is low.
Then, will narrate hereinafter according to function of the present invention.Thereby just may produce enough big power impeller is rotated because whole fluids that suck from the suction inlet external body or segment fluid flow at first clash into impeller.
Moreover, owing between impeller and rotating brush, do not have partition wall, under the situation that the suction inlet body is raised, air almost sucks and sucks from nozzle hardly from the peristome of floor entirely, therefore impeller rotates hardly, correspondingly if the operator puts in finger in the suction inlet body still secure safely accidentally.
The length of preferably setting impeller is one more medium-sized than the inner longitudinal length of suction inlet body.In routine techniques, impeller and brush element constitute on same axle, are distinct yet scraper plate exists position and impeller to have the position, exist the position can not sweep dust at scraper plate.
Therefore, there is the position in necessary shortening scraper plate and scope that propagation energy is cleaned.Because impeller and brush element constitute one, impeller can be done longly relatively like this yet in the present invention.
The speed setting of impeller is greater than 1,000r/min but less than 10, be more satisfactory in the scope of 000r/min.Reason is, if the rotating speed of impeller just can not be cleared away dust greater than 1 during 000r/min effectively.
Generally speaking, the rotating speed height of impeller, the ability of control of dust is just big, however if rotating speed surpasses 10, during 000r/min the ability of control of dust saturated and follow the impeller rotation and the noise that produces becomes quite big.
Moreover, remain on greater than-3 000Pa but be more satisfactory in the scope less than-200Pa being used for setting the static pressure that on carpet, can make carpet inside for from the area that the suction inlet external body sucks the inlet nozzle cross section of air.The cross-sectional area of inlet nozzle is according to the static pressure in the suction inlet body and definite, but under the situation of the absolute value in static pressure low (negative pressure is little) and not reaching-200Pa, air velocity through inlet nozzle bump impeller is just very low, thereby just can not produce the torque of expection.
Yet, at the absolute value height (negative pressure is big) of static pressure and above-3, under the situation of 000Pa, the suction inlet body will be by " the sticking suction " on carpet, so just be difficult to suction inlet body implementation and operation, the air that spills from floor becomes quite big in addition, and correspondingly torque is saturated.
Can obtain preferably to set forr a short time as far as possible under the essential torque condition to the diameter of impeller.Therefore, the torque that produces on carpet is more satisfactory greater than 50gr.cm (more preferably greater than 80gr.cm) but less than 200gr.cm (preferably less than 100gr.cm).In above-mentioned scope, can determine the diameter of rotor effectively.
Relative carpet, the optimum speed that cleans to be cleaned should be greater than 1, and 000r/min is (more preferably greater than 3,000r/min) but less than 10,000r/min is (preferably less than 4,000r/min).Because brush element does not contact with matting with the floor basically, so just there are not the notion of optimum speed in timber floor and matting, but consider noise problem relatively, make the noise of generation littler (being lower than 50dB).
More satisfactory rotating speed should meet following relational expression: the rotating speed of the rotating speed on carpet＞when mentioning.It yet but is to meet such relational expression in prior art: the rotating speed of the rotating speed on carpet＜when mentioning.More satisfactory torque should meet following relational expression: the torque of the torque on carpet＞when mentioning; Yet in prior art but be on carpet and when mentioning under these two kinds of conditions torque constant.
Moreover according to the present invention, all or part of fluid that sucks from the suction inlet external body at first clashes into impeller makes the impeller rotation, and the air that forms subsequently stream is sucked in the body of vacuum cleaner through face to be cleaned.
Yet in prior art, from suction inlet external body inhaled air stream is at first flowed through surface to be cleaned and air, contain the dust swept and when passing through the suction inlet body and impeller clash into.Impeller pneumatically is forced to rotation, and air is sucked in the body of vacuum cleaner afterwards.
According to the present invention, because brush element is and the coaxial setting of impeller, thus be used for that the size of suction inlet body of vacuum cleaner is little, in light weight, noise is little, and the vacuum cleaner that uses this suction inlet body can be provided.
Moreover, when mentioning the suction inlet body because the rotational automatic deceleration of impeller or stop, so can not produce because the noise that high rotating speed causes, even and the operator accidentally finger is waited when stretching into the suction inlet body, safe still secure.
Moreover because high-speed air flow also contact with floor, and dust quilt on the floor is just peeled off can carry out very smoothly, and the dust that peels off is easy to be transported to outlet nozzle, the dust concentration can improve like this in brush element and floor contact site.
Moreover, providing being sent to from the switch actuation unit under the situation of device of vacuum cleaner body not adopt the holding wire transmission means with the signal of infrared light, ultrasonic wave or radio wave form, the inside of flexible pipe and prolongation pipe just there is no need to install heart yearn, therefore the construction weight that prolongs pipe and flexible pipe just can reduce, and has also further improved maneuvering performance.
Moreover owing to need not be electrically connected at flexible pipe and junction, two ends thereof, structure just can be simplified.And, in flexible pipe, do not adorn the electric wire of using civil power, even when this worst case of hose fracture takes place, operator's safety is still secure.

Owing to sealed by carpet 401 shown in floor peristome 402 and Fig. 4, air clashes into 105 suctions and with impeller 103 mutually from inlet nozzle 106 in suction inlet body body 101, forces impeller 103 rotations so produce torque.A wall 404 of air impact suction inlet body inside subsequently is so the flow velocity of air changes angular velocity of rotation into, so air rotates with high rotation speed along arrow 405 directions.
Simultaneously, as shown in Figure 3, because air is from outlet nozzle 301 absorptions, so produced 304 and 305 speed vertically, produce the air stream 302 and 303 of vortex immediately, in these air-flows, be formed with a central axis that is parallel to floor 401 substantially.Because swirl airflow 302 and 303 is when flowing around the outer peripheral face of impeller 103, so just to the extra torque of impeller action one.
Dust on the carpet is swept and is taken away by vortex air stream 302 and 303 from floor peristome 402 by brush element 104.Air further is sucked into the body 201 of vacuum cleaner through outlet nozzle 502.
Moreover as shown in Figure 6, because wheel 602-603 sinks in the carpet, the gap that forms between floor peristome 402 and floor 401 disappears, then air almost all pass through inlet nozzle 105,106 and be inhaled into, thereby impeller 103 rotates at a high speed.
Yet as shown in Figure 7, wheel 602-603 sinks in floor or the matting hardly, the gap appears between plate face peristome 402 and floor 401, so reduce through the indrawn air capacity of inlet nozzle 105-106, the rotating speed of impeller 103 descends thereupon, and the rotating speed that is suitable for floor or matting like this is achieved automatically.
Moreover when mentioning the suction inlet body, because nearly all air-flow is to be inhaled into from floor peristome 402, impeller 103 rotate hardly, so when even the operator puts in finger in the suction inlet body accidentally, safe still secure.
Moreover as shown in Figure 8, impeller 801 is to be contorted configuration, utilizes the energy that points to the air-flow axial component 804,805 of central part from both sides of vortex air-flow in the suction inlet body just may improve the torque of impeller 801.Because axial flow 804,805th forms reverse flow, just need have the opposite distorted-structure of (relatively) direction.
Moreover, might be arranged on brush element 802,803 on the axle of impeller along the distortion of scraping plate.In addition, can rubber mass 902-903 and plate 904-905 be installed at the position that contacts with floor, so under the degree of closure situation that has increased floor peristome 402, increase, so also can improve the torque of impeller through inlet nozzle 105-106 amount of air drawn.
Be provided with two nozzles in this embodiment, air is inhaled into from the both sides of suction inlet body.Yet, two (air inlet) positions always will be set, can make the open-front of suction inlet body and make the front all as inlet nozzle.Moreover nozzle also can be arranged on the back of suction inlet body, so just can make the direction of rotation of impeller opposite.
Moreover, as shown in figure 10, by two impellers being set and, formed two impellers like this by separately direction rotation at the front and rear inlet porting nozzle of suction inlet body, just might improve the ability of gathering dust.
Moreover, as shown in figure 11, one inlet nozzle 111 can be arranged on the central part of suction inlet body, and outlet nozzle 114,115 are arranged on two (sides) end of suction inlet body, in the case, because the axial component of air-flow (or axial shunt volume) 114, the 115th, to flow in opposite direction, the distortion of impeller 116 also will be opposite configuration.
As mentioned above, impeller and the brush element by present embodiment is configured on the same axle, so the suction inlet body size of vacuum cleaner is little, in light weight, noise is also little, so just can provide the vacuum cleaner that present embodiment suction inlet body is housed.
Moreover, under the situation of mentioning the suction inlet body, because the rotational automatic deceleration of impeller or stop, so just can not producing because the noise that rotating brush sends when rotating at a high speed, even and operator when putting in finger etc. in the suction inlet body accidentally, still secure safely.
Moreover, contact the position because high-speed air flow also contacts with floor in brush element and floor, dust is peeled off from floor smoothly, the dust that peels off is transported to outlet nozzle at an easy rate, thereby has improved the function of gathering dust.
Moreover, providing being sent to from the switch actuation unit under the situation of device of vacuum cleaner body not adopt the holding wire transmission means with the signal of infrared light, ultrasonic wave or radio wave form, inside at flexible pipe and prolongation pipe just there is no need to install heart yearn, therefore the construction weight that prolongs pipe and flexible pipe just can alleviate, and has also further improved maneuverability.
Moreover owing to need not be electrically connected at flexible pipe and junction, two ends thereof, structure just can be simplified, and does not install the electric wire of using civil power in flexible pipe, even when this worst case of hose fracture takes place, operator's safety is still secure.
(embodiment 2)
Will be below in conjunction with accompanying drawing to describing in detail by the second embodiment of the present invention.
Figure 12 illustrates a top surface perspective of a suction inlet body.Among Figure 12, label 121-122 is meant the major diameter impeller, and 123 refer to a minor diameter impeller, and 124 refer to a brush element, and 125-126 refers to be used for sucking from the suction inlet external body inlet nozzle of air, and 127 refer to that an outlet nozzle and the 128-129 of suction inlet bodies refer to swirl airflow.
Then will explain work by the second embodiment of the present invention.
When the operator of a vacuum cleaner handles switch actuation unit 203 on the flexible pipe Handheld Division, mode of operation according to institute's master cock, vacuum cleaner body 201 interior blowing motor are driven, and the inhalation power that the blowing motor produces arrives at suction inlet body body 101 through flexible pipe 202 and prolongation pipe 204.
Because floor peristome 129 is closed by carpet, air just is inhaled into and clashes into impeller 121 and 122 and produce torque through inlet nozzle 125 and 126, and air just forms swirl airflow 128 subsequently.Owing to swirl airflow is rotated around the periphery of minor diameter impeller 123, impeller just obtains an additional torque.
