Above-mentioned exhaust cover body 20 is configured in the spatial portion that is provided with around the above-mentioned cleaning brush 10, exhaust cover body 20 integral body by covering the circular plate shape above the cleaning brush 10 top board 21 and the peripheral part of the bottom surface of this top board 21 with surround above-mentioned cleaning brush 10 around mode form inboard row gas hood 22 and the outboard row gas hood 23 that inside and outside bilayer and devices spaced apart ground are set up in parallel downwards, form the bottom surface opening shape, the inner space of inboard row gas hood 22 forms the brush chamber 20A of above-mentioned cleaning brush 10 rotations.
Both sides are separated by above-mentioned inside and outside hood 22,23 and the space of the top bottom surface opening shape that is covered by top board 21 forms exhaust chamber 20H, each top ports of above-mentioned left and right sides blast pipe 14L, 14R be connected in the cross section be the bottom surface open-type the summary toroidal this exhaust chamber 20H about above, utilization is by the exhaust of two above-mentioned air blasts 12 of sending of pipe 14L, 14R, increase the pressure in the exhaust chamber 20H, by the pressure of this increase, to above-mentioned exhaust cover body 20 integral body to the ascent direction application of force of floating from ground FL.
In addition, in the inside and outside hood 22,23 that constitutes above-mentioned exhaust cover body 20, shown in the cutaway view of Fig. 5, the lower-upper length of the above-mentioned outboard row gas hood 23 of ratio that the lower-upper length of inboard row gas hood 22 is provided with is long, so that its bottom side contacts with ground FL, the summary that the lower-upper length of this outboard row gas hood 23 is provided with is short, so that its bottom side and ground FL leave gap FX.
In Fig. 2, though the exhaust cover body 20 that as above constitutes forms the structure that hangs by bar 20T from main body 1A, the structure that this exhaust cover body 20 has formed the outside that covers cleaning brush 10 and upside and can roughly move down in vertical direction along ground FL shown in arrow a.And above-mentioned left and right sides blast pipe 14L, 14R are made by flexible pipe (serpentine canal) in an embodiment, along the main body side, from the top with the direction of exhaust cover body 20 approximate vertical on be communicated with the top board 21 of exhaust cover body 20.
As limiting the method that exhaust cover body 20 only can be mobile down in vertical direction with respect to main body 1A, effective method is to utilize a plurality of cylinders to connect, perhaps make the axle of the top board 21 that protrudes in hood 20 bodies be embedded in the hole portion of the bottom surface that is arranged on main body 1A, on one side the exhaust cover body 20 and the gap of brushing between 10 are maintained certain distance, can up or down support exhaust cover body 20 on one side.
And, Fig. 3 is the bottom view of the floor surface washing machine 1 of the embodiment of the invention, as shown in the figure, and for the exhaust cover body 20 around the cleaning brush 10, at first make inboard row gas hood 22 and cleaning brush 10 separate the gap, separate equally spaced space afterwards outboard row gas hood 23 is set.The space of the donut-like (ring-type) that this inboard row gas hood 22 and outboard row gas hood 23 form has formed above-mentioned exhaust chamber 20H, blast pipe 14L, 14R about above-mentioned are with the lower port opening, and being communicated in this exhaust chamber 20H from last direction vertical lower, left and right sides blast pipe 14L, 14R all are connected with exhaust chamber 20H at two places in an embodiment.
Left and right sides blast pipe 14L, 14R need not must vertical engagement in the top board 21 of exhaust cover body 20, also can tangentially be connected from the peripheral part of exhaust cover body 20 with exhaust chamber 20H, just passable as long as the gravity of blast pipe 14L, 14R about noting avoiding and the crooked reaction force that causes influence moving up and down of exhaust cover body 20.
Though detailed icon not, but exhaust cover body 20 and cleaning brush 10 and the motor 10M that makes cleaning brush 10 rotations, can separate from ground FL rising by the brush lifting pedal 25 of application drawing 3, squeegee 11 can separate from ground FL rising by the squeegee lifting pedal 26 shown in the application drawing 3.
Figure 4 shows that the major part cutaway view of the embodiment of floor surface washing machine of the present invention, is the figure for A-A section formation, that Fig. 3 is shown that exhaust cover body 20 and cleaning brush 10 and squeegee 11 are described.
About blast pipe 14L, 14R be communicated in the top board 21 of exhaust cover body 20 from last direction vertical lower, consequently scavenging action is to the exhaust chamber 20H in the space that outboard row gas hood 23 and inboard row gas hood 22 and climax 21 separate, in the present embodiment, by affacting equably in the exhaust chamber 20H about left and right sides blast pipe 14L, 14R.Feed pipe 9 shown in two pecked lines and water supply direction arrow show the appearance that rinse water CW is provided near the cleaning brush 10 of the brush chamber of Fig. 4 20A, the 10R of communication channel up and down of the central part of rinse water CW by being positioned at cleaning brush platform 10T splashes into the perimembranous of cleaning brush 10.
In Fig. 4, though store rinse water CW at inboard row gas hood 22 with between brushing 10, even but the integral body of floor surface washing machine 1 moves forward and backward under this state, owing in exhaust chamber 20H, there is exhaust to flow into, therefore become the above high pressure conditions of atmospheric pressure, its reaction force to the integral body of exhaust cover body 20 to the ascent direction application of force, with ground FL and inside and outside hood 22, the friction of 23 contact site is suppressed at extremely low degree, do not worry inside and outside hood 22,23 pairs of wearing and tearing that ground FL causes can be implemented washing and cleaning operation to ground FL expeditiously when preserving rinse water CW.In Fig. 3 to Fig. 5,10K is brush motor flange.
And, under the state of Fig. 4, carry out ground when cleaning, when output excessively increases when causing too much storing rinse water CW in brush chamber 20A, there is the recovery situation of difficult of cleaning back rinse water CW.Promptly under the situation that has a large amount of rinse water CW to flow out on the attraction power of squeegee 11, (brush lifting pedal 25 by operation from exhaust cover body 20, make under the situation of cleaning brush 10 and 20 risings of exhaust cover body), when rinse water flowed out on a large scale, the recovery of using squeegee 11 to carry out rinse water CW will spend suitable time and labor.
Require the main points of record in 4 as aforesaid right of the present invention, the lie 20X (with reference to figure 4) that is communicated with brush chamber 20A and outside is arranged on predetermined altitude, make that being stored in the above rinse water CW of this height is discharged to squeegee 11 sides as overflow, and can keep the moisture-holding capacity that conforms to the recovery ability.And in an embodiment, this lie 20X only is provided with a place on squeegee 11 directions, also can a plurality of lie 20X be set at the rear side of the main body 1A of squeegee 11 directions ...
In addition, when determining the height of lie 20X, as shown in Figure 4 and Figure 5, rinse water CW is because the centrifugal force that cleaning brush 10 rotations produce, close to the peripheral direction of cleaning brush 10 easily, and along with having the tendency of rising near water level laterally, so the suitable height of the setting of the rotary speed by cleaning brush 10 is also inequality, therefore be with height setting adjustable be effective method.
Figure 5 shows that the major part schematic diagram in the B-B cross section of above-mentioned Fig. 3, because the connection status of left and right sides blast pipe 14L, 14R is difficult for judging among above-mentioned Fig. 4, therefore express the appearance that exhaust pipe 14L, 14R only are communicated to exhaust chamber 20H among Fig. 5, the state that exhaust does not affact brush chamber 20A also is shown.
And, shown in the embodiment of Fig. 4, though make inside and outside hood 22, the method that 23 height is identical also is effective, but it is inferior in the situation that the attraction that makes air blast 12 is variable, it is required when above when capacity is increased to, the interior excessive pressure of exhaust chamber 20H of exhaust cover body 20 is increased, exhaust cover body 20 integral body are floated to ascent direction, the result has rinse water CW and flows to outside possibility, therefore as the main points shown in the claim 2 of the present invention, Fig. 5 shows following characteristics: the lower end length than outboard row gas hood 22 low (length is longer) that the lower end height of inboard row gas hood 23 is provided with, inboard row gas hood body 22 lower ends are contacted with ground FL easily, and the lower end of outboard row gas hood 23 and ground FL leave gap FX.
Like this, by improving the seal of inboard row gas hood 22, and the lower end of outboard row gas hood 23 and ground FL leave the formation of gap FX, shown in Fig. 5 two pecked line arrow R, since with the excessive channel setting of exhaust in the outside, therefore always the stable climbing power that exhaust pressure produced of ascent direction is put on exhaust cover body 20, the rinse water CW spillover that exhaust cover body 20 come-ups excessively cause when having avoided exhaust too much.
Utilize the air quantity of exhaust and the capacity of exhaust chamber 20H that the lower end difference in height of inboard row gas hood 22 and outboard row gas hood 23 is changed, the stable power of ascent direction can be put on exhaust cover body 20, in addition the easy non-return valve structure of the excessive usefulness of gas also can be set at the peripheral part of exhaust cover body 20.
Figure 6 shows that the major part detailed section view of other embodiment of floor surface washing machine of the present invention, in this embodiment, main points as claim 3 of the present invention, exhaust cover body 20 is not an one, the part that contacts with ground FL is made of the parts of bendable material, part or all of above-mentioned exhaust cover body constitutes with flexible parts, is made of than the easy crooked shape of inboard row gas hood the outboard row gas hood at least.Promptly be installed in the bottom surface sections of above-mentioned exhaust cover body 20 and constitute the flexible outboard row gas hood 23H of portion of flexible exhaust cover body 20 ', constitute by easy shape to the bending direction bending shown in the arrow X of Fig. 6, therefore inferior in the variable situation of the attraction that makes above-mentioned air blast 12, when increasing capacity to required when above, this outboard row gas hood 23H of portion is crooked laterally, be opened to and the inboard row gas hood 22H of portion between spatial portion 20Z, exhaust in the exhaust chamber 20H is discharged by connected entrance 20S, thereby can bring into play the effect same with the above-mentioned exhaust cover body that is provided with the ladder difference 20.
Fig. 7 is that integral body forms the roughly detailed maps of the above-mentioned flexible exhaust cover body 20 ' of bagel shape, (1) is plane, (2) be side view, (3) oblique view for seeing from the inside, can the pad pipe 22T of portion be set at the inboard row gas hood 22H of portion in the enforcement, so that the tracing ability of effective raising and ground FL.In addition, for realizing so flexible outboard row gas hood 23H of portion, the linear parts of one that will have the cross sectional shape of the flexible outboard row gas hood 23H of portion shown in Figure 6 bends to circle and is usual way with bonding making the in two ends, for exhaust chamber 20H and spatial portion 20Z are connected, can a plurality of connected entrance 20S be set as figure.At this moment, after the linear parts of one that will have the cross sectional shape of flexible outboard row gas hood 23H of portion and the inboard row gas hood 22H of portion is shaped, press predetermined length and shear, and by stamping engineering with connected entrance 20S opening, and with the bonding formation circle in front and back end.
In the floor surface washing machine 1 that constitutes like this, even the quantity delivered of the rinse water CW that in common ground washing and cleaning operation brush chamber 20A is supplied with is few, because rinse water CW is difficult to overflow to the outside from brush chamber 20A, therefore can keep cleaning force, in addition, because rinse water CW keeps to such an extent that the time is elongated, thereby has improved cleaning force.
