Description

TECHNICAL FIELD The present invention relates to a floor cleaning machine in which a cleaning liquid is supplied to a surface to be cleaned and cleaned by a rotary cleaning tool.

2. Description of the Related Art Conventionally, in this kind of floor cleaning machine, a base portion having a rotary cleaning tool driven by a motor, a suction port body, and provided with moving wheels, and a front portion of the base portion The base cover is pivotally supported on the base so that the rear side can be displaced in the vertical direction, and the base cover is provided with a cleaning liquid tank for supplying a cleaning liquid to the surface to be cleaned. A partition wall was formed inside the cleaning liquid tank to prevent the liquid inside from spilling when the cleaning machine was moved.

However, with the above configuration, when the base cover is lifted upward during maintenance, if the cleaning liquid remains in the tank, it will be inadvertently drained off. I had to do it. Moreover, the partition wall obstructed the draining of the liquid, which took time.

Further, when the above tank is washed with water, it is necessary to carry out the washing operation with the remaining hand while holding the hose connected to the tap water with one hand, which makes the work extremely difficult.
Furthermore, in this case also, the partition wall was an obstacle.

The present invention solves such conventional problems and improves workability during maintenance.

Means for Solving the Problems To achieve the above object, the present invention has a motor and a rotary cleaning tool driven by the motor, a battery for power supply, a suction port body, a controller, and a moving wheel. It is provided with a base part provided and a base cover pivotally supported on the front part of the base part so that the rear side can be displaced in the vertical direction. The base cover has a suction force of an electric fan. A sewage recovery tank for suctioning and storing sewage on the surface to be cleaned through the suction port body and a cleaning liquid tank for supplying a cleaning liquid to the surface to be cleaned are provided, and the front of the upper opening of the cleaning liquid tank is closed by a lid, Further, a plurality of hose insertion holes having different diameters are provided at the rear part of the lid so as to communicate with each other, and the width of the communication portion is made smaller than the diameter of the insertion hole on the smaller diameter side.

Operation In the above invention, even if the base cover is lifted up for maintenance or the like, the liquid in the cleaning liquid tank is prevented from flowing out by the lid displaced in the vertical direction. Further, even when the inside of the tank is washed with water, the lid has a function of preventing water splash. Furthermore, if the hose is inserted and held in the insertion hole of the lid, cleaning work can be performed with both hands. In addition, since a plurality of insertion holes having different diameters are formed, there is no problem even if the diameter of the hose changes. Moreover, since the width of the communicating portion is small, the hose can be firmly supported.

Embodiments Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, a base 2 provided with moving wheels 1 is a motor 3
And a rotary cleaning tool 4 driven by this motor 3 and a battery 5 for power supply, and a suction port body 6 at the rear lower part thereof.
And a controller 7 on the top. A base cover 9 whose lower front end is pivotally supported by a front portion of the base portion 2 via a hinge 8 can be opened upward by displacing a rear side of the base cover 9 in an upward direction. There is. The base cover 9 has a substantially box-like shape with its lower and rear portions opened, and the top wall portion has a negative pressure area due to the suction force of the electric fan 10, whereby the suction port body 6 is interposed. A sewage recovery tank 11 for sucking and storing sewage on the surface to be cleaned is provided, and a cleaning liquid tank 12 for supplying a cleaning liquid to the surface to be cleaned is provided.

A lid 13 is provided in front of the upper opening of the cleaning liquid tank 12.
And a plurality of hose insertion holes 14 and 15 having different diameters are formed in the rear portion of the lid 13.

Reference numeral 16 is a hose that connects the suction port body 6 and the sewage recovery tank 11, 17 is a drain hose derived from the sewage recovery tank 11, 18
Is a liquid supply hose led out from the cleaning liquid tank 12, 19 is a handle, and 20 is a main body lid. 21 is a hose, 22 is a hose insertion hole
A hose insertion hole with a small diameter at the communicating part where 14 and 15 communicate.
Its width is smaller than 14.

In the above configuration, the cleaning liquid in the cleaning liquid tank 12 is supplied to the surface to be cleaned from the liquid supply hose 18, and the surface to be cleaned is cleaned by the rotating operation of the rotary cleaning tool 4. After the cleaning is finished, the supply of the cleaning liquid is stopped, and the suction force of the electric fan 10 causes the dirty water recovery tank 11 to be in the negative pressure region. by this,
Sewage on the surface to be cleaned is collected through the suction port body 6 and the wastewater recovery tank 11
Is collected by suction. In addition, the collected sewage can be discarded at a predetermined place by using the drain hose 17.

Next, the maintenance work will be described.

First, for cleaning the cleaning liquid tank 12, the hose 21 connected to the tap is inserted into one of the hose insertion holes 14 and 15 of the lid 13.

Therefore, it is not necessary to hold the hose, and cleaning work can be performed with both hands. Of course, since a plurality of hose insertion holes 14 and 15 having different diameters are formed, the type of hose diameter is not affected. In addition, the communication portion 22 allows the hose 21
Is strongly held, and the hose 21 does not come off due to reaction force when pouring water.

Further, when the rear side of the base cover 9 is displaced upward while the cleaning liquid is stored in the cleaning liquid tank 12 and the upper part of the base 2 is opened, as shown in FIG. There is no risk of liquid spilling because it acts like a weir.

Therefore, it is not necessary to drain the cleaning liquid tank 12 each time maintenance of the equipment on the base 2 is performed.

In addition, the lid 13 also functions as a dam during the cleaning work, and prevents the cleaning liquid from flowing out due to the fluctuation of the liquid surface as shown in FIG.

As described above, according to the present invention, the front of the upper opening of the cleaning liquid tank is closed by the lid, and a plurality of hose insertion holes having different diameters are formed at the rear of the lid. It has a practical effect.

i. When the rear side of the base cover is displaced upward while the cleaning liquid is stored in the cleaning liquid tank and the top of the base is opened, the lid is displaced vertically and it looks like a weir. There is no risk of liquid spilling from where it exerts its action. Therefore, it is possible to easily and efficiently inspect equipment during the cleaning work.

ii. The lid exerts a weir action even during washing work, and prevents the washing liquid from flowing out due to the fluctuation of the liquid surface.

iii. When cleaning the cleaning liquid tank, by inserting a hose from the water tap into the hose insertion hole formed in the lid, it is not necessary to hold this hose, and you can reasonably perform cleaning work with both hands. . Of course, since multiple hose insertion holes with different diameters are formed, it is not affected by the type of hose diameter, and since the hose 21 is strongly retained by the communication part 22, it does not react when pouring water. The hose will not come off due to force.

iv. Also, since there is no partition wall as in the past, it is easy to clean the inside.
