The invention relates to apparatus for cleaning the floor with a brush attachment, which is rotatably mounted brush roller and which has at least one located near the brush roller suction nozzle, and attached to the brush nozzle can be rotated counter, which is the suction unit, and a reservoir for liquid detergent, which is applied to be cleaning the floor surface, and the tank for dirty liquid for receiving sassenou with the suction unit from the surface of the floor of the contaminated fluid, the reservoir for liquid detergent and tank for dirty liquid together form made with opportunity detachable connection with a rack constructive node tanks.

Such devices for cleaning the floor is known from US 2006/0000050 A1. With their help, you can clear the floor surface due to the possibility of applying to the surface of the liquid detergent and cleaning her brush roller. Put liquid detergent together with the dissolved dirt can under suction action of the suction unit to be redirected to the tank for dirty water.

Both the tank and the suction unit mounted on the rack apparatus for cleaning the floor. The stand can be rotated installed with the op who swarm on the brush head, usually, at its free end has a handle. Using the rack, the user can move the device for cleaning the floor on the subject of cleaning a floor surface.

In the US 2006/0000050 A1 proposes the implementation of a reservoir for liquid detergent and tank for dirty liquid in the form of shared construction unit of tanks, which is made with the possibility of permanent connection with the stand. Constructive node reservoirs may be separated from hours to fill the tank for liquid detergent and emptying of the tank for dirty water. However, the combined filling and emptying of the construction unit of tanks required in all cases. Often, after using the machine for floor cleaning only needs emptying of the tank for dirty water without simultaneous new tank for liquid detergent. On the contrary, reseeding in many cases are only in the beginning of the new use of the apparatus for cleaning floor, thus emptying the tank for dirty liquid is not required. Therefore, the execution of a tank for liquid detergent and tank for dirty liquid in the form of joint construction unit reservoirs in some cases leading to difficulty in use of the apparatus for cleaning floor is.

The present invention is to improve apparatus for cleaning the floor is known from the prior art design so that it was easy to use.

According to the invention this task in the apparatus for cleaning the floor above species solved due to the fact that the reservoir for liquid detergent is made with the possibility of permanent connection with the tank for dirty water.

In the apparatus for cleaning floor according to the invention a reservoir for liquid detergent in combination with a tank for dirty water though and forms a joint constructive node, which, as such, may be separated from the rack apparatus for cleaning the floor, but with the addition of a reservoir for liquid detergent can also be separated from the tank for dirty liquid, that is, both tanks are detachable from each other. This facilitates use of the apparatus for cleaning the floor. For example, at the beginning of the floor cleaning tank for liquid detergent can be removed from the tank for dirty water, and then a simple way to fill liquid detergent. After that, a full tank for liquid detergent can again be connected with the tank for dirty liquid, so that both reservoirs form a common structural node tanks, which is mounted on tone apparatus for cleaning the floor. If the tank for dirty liquid is full, you can first separate from the rack design site tanks. Then, a reservoir for liquid detergent can be removed from the tank for dirty water, so a full tank for dirty liquid can be attributed to the location of the drain for dirty water and there empty. Then empty the tank for dirty liquid can again be connected with a reservoir for liquid detergent, and thus obtained a General constructive node tanks can be mounted on the rack apparatus for cleaning the floor.

The ability to disconnect both of the tank in the form design node from the rack, and then separate both reservoirs from each other facilitates the user to operate the apparatus for cleaning the floor.

Particularly useful if a reservoir for liquid detergent made with the possibility of separation from the tank for dirty liquid while maintaining the connection between the tank for dirty liquid and stable. This embodiment provides the possibility to leave the tank for dirty liquid on the counter and, nevertheless, removing from the front of the tank for liquid detergent. The fact that such a constructive implementation of a reservoir for liquid detergent may be separated from the tank for dirty water without having to hold the mA connection between tank for dirty liquid and stable. Due to this, the filling of a tank for liquid detergent is implemented especially simply because the user has to manipulate only a reservoir for liquid detergent, and a tank for dirty liquid can remain on the rack.

In one preferred form of execution of a reservoir for liquid detergent is located on the side near the tank for dirty water. The advantage of this arrangement is that both reservoirs are located almost at the same height relative to be cleaned floor surface. During operation of the apparatus for cleaning the floor of the tank for liquid detergent is gradually emptied, and at the same time filled the tank for dirty water. If both reservoirs are located one above the other, the result during operation is the change of the load, which is provided on a user usually located during operation of the apparatus for cleaning a floor inclined stand. If the tank for dirty liquid is above the tank for liquid detergent, increases the load that the user must move during operation of the apparatus for cleaning the floor as gravity tank for dirty liquid increases. If both reservoirs are almost the same the first height, the user is not experiencing significant load change. This increases the comfort of using the device for cleaning the floor.

Preferably, a reservoir for liquid detergent is located on the front of the tank for dirty water, as this facilitates the availability of a tank for liquid detergent for the user and simplifies the use of the apparatus for cleaning the floor.

For example, it may be provided that the tank for dirty liquid is available to the side of the recess, into which may be inserted a reservoir for liquid detergent. Preferably, the recess is located on the front side of the tank for dirty water.

Particularly useful if a reservoir for liquid detergent is made with the possibility detachable fixation with the tank for dirty water, because this tank for liquid detergent can be simply separated from the tank for dirty liquid and again connected with it.

In order to load experienced by the user due to the usually inclined during operation of the apparatus for cleaning the floor the position of the rack and secured to it of the aggregates, was particularly low, in one preferred variant of the invention, the suction unit is made in the form of a bypass to the suction unit and is mounted n the rack under the design node of the tanks, consisting of a tank for liquid detergent and tank for dirty water. Due to the location of the suction unit under the design node of the tanks he has only a small distance to the axis of rotation of the rack. Due to this, the load that the hour has on the user during operation of the apparatus for cleaning a floor, can be kept low.

Particularly favorable, if the axis of rotation of the suction unit is directed coaxially of the axis of rotation of the rack. When you suction unit by turning the rack does not exert torque on the rack, on the contrary, the suction unit is rotated around its own axis of rotation, i.e. around the axis of the turbine, which is located coaxially of the drive axis of the electric motor.

In order to cause the rotation of the mounted rotatably on the brush nozzle brush roller, can be applied to separate the motor brushes. However, this leads to constructive labor-intensive and relatively large execution brush nozzle. Therefore, in one preferred implementation of the brush roller by means of a transmission connected to the motor of the suction unit. The motor of the suction unit actuates the suction turbine and additionally serves to PR the water brush roller.

It is particularly favorable, if the direction of rotation of the brush roller is identical to the direction of rotation of the motor. Thus the direction of rotation of the suction turbine is also identical to the direction of rotation of the brush roller. It turned out that due to this brush nozzle can be made particularly compact, so it has only a relatively small structural volume. In addition, due to the General direction of rotation of the suction unit and the brush roller can reduce the cost of manufacturing and installation of the brush head.

As the transmission, whereby the motor of the suction unit connected to the brush roller, in one preferred embodiment, the invention is applied, the belt drive. In connection with the General direction of rotation of the suction unit and the brush roller does not need to be crossed to ensure a reversal of the direction of rotation. Therefore, the belt drive requires only a small structural space, and its mechanical load can be kept low.

Useful if transmission apparatus for cleaning the floor, when seen in a direction from the vehicle ahead, is located on the left side of the brush head. The advantage of this is that the brush roller can extend the ome to the right edge of the brush head, and this in turn allows you to place the brush attachment for cleaning a floor surface at a very small distance from the bounding surface of the floor wall, and it is ergonomically favorable, on the right side of the brush nozzle for consideration in the forward direction. Thus, the apparatus for cleaning floor has the advantage that it has a very small distance from the edge on the right side, that is, the brush roller can be located on the right side of the apparatus for cleaning the floor very close to the wall.

Particularly useful if the direction of rotation of the suction unit when considering in the direction of the motor is the counterclockwise direction. Preferably, the suction unit is, when seen in axial direction, in front of the motor. When looking at the motor and its drive shaft, and thereby also the suction unit, and the brush roller rotates in a counterclockwise direction. Thus, the direction of rotation of the brush roller coincides with the direction of rotation is preferably used running wheels, which are rotatably installed based on the brush nozzle. Thus, rotational movement of the brush roller increases foward apparatus for cleaning the floor.

The following description of the preferred in the approaches of carrying out the invention in conjunction with drawings is a more detailed explanation. In the drawings shown:

figure 1 - schematic view in partial section of the apparatus for cleaning floor according to the invention;

figure 2 is a side view of the overall construction unit reservoirs are presented in figure 1 apparatus for cleaning the floor, containing a reservoir for liquid detergent and a tank for dirty water, and

figure 3 - side view presented in figure 1 structural node tanks, with a reservoir for liquid detergent is separated from the tank for dirty water.

1 schematically shows indicated generally by the reference designator 10, the apparatus for cleaning the floor in the form of a partial section. It contains a brush nozzle 12, which can be rotated around the axis 14 of rotation set hour 16. She is not shown in the drawing, the free end has a handle that the user can easily grasp the rack 16.

Brush nozzle 12 includes a housing 18 in which is set the brush roller 20 rotatably around directed parallel to the axis 14 of rotation of the axis 22 of rotation. In the direction of the translational motion of the apparatus 10 for cleaning the floor in front of and behind the brush roller 20 brush nozzle 22 has front and rear suction nozzle 24, 26, the free ends of which are located a pair of suction pads 28 or 30. Both the suction nozzle 24 and 26 districts which are in liquid communication with the suction pipe 32. The suction pipe 32 is in communication with the bypass suction unit 34, which in the suction pipe 32 may be created in a vacuum. At its free, drawn from the suction nozzles 24, 26 end, the suction pipe 32 has a suction connector 36, which, as well as the suction unit 34 mounted on a rotary support 16.

The direction 35 of rotation of the suction unit 34 is identical to the direction 21 of rotation of the brush roller 20. The suction unit 34 to actuator has an electric motor 38, the drive shaft 40 which is coaxial to the axis 14 of rotation. By means of a belt drive 42 drive shaft 40 is in rotational connection with fixed without the possibility of rotation of the brush roller 20 belt pulley 44, the motor 38 can be brought into rotation in the same direction as the suction unit 34 and the brush roller 20. The transfer of rotational motion from the motor 38 to the brush roller 20 through the transmission, which has no change on the reverse (reversing) the direction of rotations of the elements, such as gears or the like.

The suction unit 34 when seen in the axial direction is in front of the motor 38. If you look at the motor 38, its drive shaft 0 and thereby, also the suction unit 34 and the brush roller 20 rotate counterclockwise. Thus, the direction 21 of rotation of the brush roller 20 coincides with the direction 46 of rotation mounted on the brush attachment 12 of the traveling wheels 45, and the rotation of the brush roller 20 increases 49 moving forward apparatus 10 for cleaning the floor.

Transmission, that is, the belt drive 42 is located relative to the translational direction 49 of the apparatus 10 for cleaning the floor on the left side of the brush nozzle 12. The brush roller 20 extends approximately to the right edge of the brush nozzle 12. This allows for cleaning a floor surface to position the brush roller 20 at a very short distance from the bounding surface of the floor wall, and it is ergonomically favorable, on the right, when considering in the forward direction 49, the side brush nozzle 12. Thus, the apparatus 10 for cleaning the floor differs little distance from the edge on the right side, that is, the brush roller 20 can be located on the right side of the brush nozzle 12 is very close to the wall. This greatly facilitates use of the apparatus 10 for cleaning the floor.

On the stand 16 with fixed separation constructive node 47 tanks, which includes a reservoir 48 for dirty fluid reservoir 50 for liquid detergent is th funds. Both reservoirs 48 and 50 can be separated from the rack 16. Using fixing (locking) connection they are connected to the housing 52 of the rack, which includes enclosing the suction unit 34 of the lower part 54 of the rack enclosure and overlying structural node 47 tanks the upper part 56 of the rack enclosure. Additionally, the housing 52 of the rack has a middle portion 58 of the rack enclosure with the base wall 60 of the rack enclosure, through which the upper part 56 of the rack enclosure connected with the bottom part 54 of the rack enclosure.

The reservoir 48 for dirty liquid on its upper side has a suction nozzle 68, which sealing manner communicates with the connecting piece 70 when inserted into a reservoir 48 for dirty water in the receiving section 66. The fitting 70 is located at the free end of the connecting pipe 72, which is on its facing away from the connecting part 70 end of a pipe 74, which is inserted in the suction connector 36. Departing from the suction connector 36, the connecting drobopro the d 72 is held on the first segment 76 along the rear side of the supporting wall 60 of the rack enclosure. The first section 76 of the pipeline inside the upper part 56 of the rack enclosure adjacent arcuate second section 78 of the pipeline.

The tank 50 for liquid detergent has on the lower side of the discharge part 80, which communicates with located on the lid 62 of the lower part 54 of the rack enclosure mounting nipple (not shown). Connecting nipple through the exhaust manifold (for the sake of better clarity, the drawing also not shown) is a hydrodynamic connection with the above the brush roller 20 and parallel to the axis 22 of rotation of the distribution pipe 82, which has many located at a uniform distance from each other of the outlet 84. The movement of liquid detergent from the reservoir 50 to the liquid detergent through the exhaust manifold to the distribution pipe 82 is performed through a liquid pump, which for the sake of better clarity, the drawing is also not shown.

A reservoir for liquid detergent can be filled with liquid detergent, preferably water, to which, if necessary, may be blended with a cleaning chemical. Proceeding from the reservoir 50 for detergent, liquid detergent can flow to the distribution pipe 82 and out through the outlet opening 84 so that it is applied with a brush is cnym roller 20 to be cleaning the floor surface. The floor surface may be processed through a moistened brush roller 20, and the applied liquid can together with the dissolved dirt through both the suction nozzle 24, 26, adjacent the suction pipe 32 and a connecting pipe 72 to flow into the reservoir 48 for dirty water. The necessary suction flow produced by-pass suction unit 34.

The tank 50 for liquid detergent is located on the front of the tank 48 for dirty liquid and can be separated from it, not only when it was extracted from the admissions section 66, but when the tank 48 for dirty water recorded in the admissions section 66. To do this, on its front side the tank 48 for dirty fluid has a recess 88 into which can be inserted into the tank 50 for liquid detergent, while it is fixed with the possibility of separation from the reservoir 48 for dirty water.

If you want to fill the tank 50 for liquid detergent, then you only need to disconnect it from the tank for dirty liquid 48. After that full tank 50 for liquid detergent can be again inserted into the recess 88, at the same time set the hydrodynamic coupling between the discharge part 80 and the corresponding connecting the nipple is.

If you want to empty the tank 48 for dirty water, it can be extracted from the receiving section 66 together with the tank 50 for liquid detergent. Then the tank 50 for liquid detergent can be removed from the tank 48 for dirty water, and the latter can be a simple way drained.
