[001]

[Industrial applications]

 The present invention relates to a floor cleaning machine capable of spraying a cleaning liquid on the floor, polishing the floor surface, and sucking and removing a waste cleaning liquid while freely moving back and forth and right and left.

[002]

[Prior art]

 In general, the work of cleaning the floor surface is performed by applying a cleaning liquid to the floor surface and then rubbing it with a brush or a pad to separate the dirt from the floor by the chemical action of the cleaning liquid and the physical action of friction. The dirty cleaning waste liquid is scraped off with a rubber spatula called a squeegee and removed. The floor cleaner is one machine that performs three operations such as spraying the cleaning solution on the floor, rubbing the floor with a brush or pad, and collecting and removing dirty cleaning waste solution. is there. An example of the structure and operation of a conventional floor cleaning machine will be described with reference to FIGS. 6 and 7. The floor polishing disk (20) to which the brush (19) and the like are attached can be rotated by the electric motor (21) to polish the floor. A cleaning liquid tank (22) is arranged above the electric motor (21), and the cleaning liquid is filled in the cleaning liquid tank (22), passes through the cleaning liquid supply pipe (24) and the cleaning liquid supply valve (23), and then the floor polishing circle. The cleaning liquid is sprayed from the cleaning liquid spraying port (25) arranged near the plate (20). The spray amount of the cleaning liquid can be controlled by opening and closing the cleaning liquid supply valve (23). A cleaning waste liquid recovery tank (26) is arranged behind the cleaning liquid tank (22), and a negative pressure is maintained by a vacuum pump (27). The floor can be removed by the chemical action of the cleaning liquid supplied from the cleaning liquid tank (22) and the physical action of the floor polishing of the brush (19). Dirt is dissolved in the cleaning liquid, and the dirty cleaning waste liquid is collected by the rubber squeegee (28) that is in close contact with the floor behind the floor polishing disc (20) and the cleaning is performed immediately before the squeegee (28). It is sucked from the waste liquid suction port (18) through the suction hose (29) to the cleaning waste liquid recovery tank (26) under negative pressure. Then, the cleaning waste liquid is completely recovered, and the floor is in a clean state. Since the squeegee (28) is behind the floor cleaning machine, the floor cleaning machine must be moved forward when collecting the cleaning waste liquid, so the movement while performing the floor cleaning is a forward movement. These operations are controlled by the control panel (31) near the operation handle (30) and can be operated by one person, so that floor cleaning can be performed by one person. In addition, as another example of the floor cleaning machine, the floor cleaning machine is equipped with an electric motor for cleaning the floor, a cleaning liquid, etc., and therefore becomes heavy in weight.Therefore, a traveling electric motor is provided and the electric power of the electric motor enables forward movement. Traveling floor washer is also used.

[003]

[Problems to be solved by the device]

 This had the following drawbacks. (B) Since the conventional floor cleaning machine can only move forward during cleaning, it is necessary to change the direction when moving to the wall. Therefore, even if the floor washer can be approached and the floor can be washed at a narrow place as narrow as the width of the floor washer, such as under a desk, it cannot change the direction. In step 28), the cleaning waste liquid cannot be collected and the floor cannot be cleaned. (B) When changing the direction of the floor cleaning machine, the cleaning waste liquid collected in the squeegee (28) may be scattered to the outside of the floor cleaning machine by centrifugal force, and since the scattered cleaning waste liquid is collected, the squeegee (28) ) Is made longer than the width of the floor washer. However, when cleaning the floor near the wall in the room, it is necessary to separate the floor cleaning machine from the wall by the amount of the squeegee that is overhanging, and it is not possible to clean the floor in every corner. (C) Since the conventional floor cleaning machine is equipped with the electric motor (21), the cleaning liquid, etc., it is heavy and requires a large force to move it forward, which imposes a heavy burden on the operator. (D) Since the electric traveling type floor cleaning machine is equipped with a traveling electric motor, the size of the device becomes large and it becomes impossible to clean the floor in a narrower area. (E) Since the electric traveling floor washer is heavier than the traveling electric motor, it is difficult to carry. This proposal was made to solve these drawbacks.

[004]

[Means for Attempting to Solve the Problems]

 In a floor cleaning machine that sprays cleaning liquid onto the floor surface, polishes the floor, and can suction and remove cleaning waste liquid, a suction pipe with a cleaning waste liquid suction port (2) on the outer circumference of the floor polishing disc (3) ( Attach it so that it surrounds 1). It is a floor cleaning machine having the above configuration.

[0095]

[Action]

 Since the present invention is the floor cleaning machine having the above-mentioned configuration, since the suction port (1) for sucking the cleaning waste liquid surrounds the outer periphery of the floor polishing disk (3), the floor cleaning machine can be moved back and forth and left and right. Even if it is done, the cleaning waste liquid can be sucked. Also, by tilting the floor polishing disc (3) back and forth and left and right, the floor cleaning machine moves in the direction opposite to the rotation direction of the tilted side of the floor polishing disc (3) due to the repulsive force of the rotation of the disc. The operator can easily move the floor cleaner simply by tilting the floor polishing disc (3).

[0096]

【Example】

 An example of the floor cleaning machine of the present invention will be described with reference to FIGS. 1, 2, 3 and 4. A brush (4) for polishing the floor is attached to the floor polishing disc (3). The floor polishing disc (3) can be rotated by an electric motor (5) and is attached to a support rod (17). An operation handle (16) is attached to the support rod (17) so that an operator can easily grasp it. The cleaning liquid tank (6) for containing the cleaning liquid is attached in front of the support rod (17). The cleaning solution tank (6) is provided with a cleaning solution supply pipe (9) and a cleaning solution supply valve (8), and the cleaning solution spray port (10) is attached near the floor polishing disk (3). The floor polishing disc (3) is provided with a cleaning liquid permeation hole (11) so that the cleaning liquid can flow to the floor surface. A cleaning waste liquid recovery tank (12) is attached to the rear of the support rod (17). A vacuum pump (13) is installed above the cleaning waste liquid recovery tank (12) to bring the cleaning waste liquid recovery tank (12) into a negative pressure state. It is attached to the outer periphery of the floor polishing disc (3) so as to surround the suction pipe (1). The suction pipe (1) is provided with a plurality of cleaning waste liquid suction ports (2). A squeegee (14) is attached to the outer periphery of the suction pipe (1) to prevent the cleaning waste liquid from leaking to the outside of the floor polishing disc (3). Connect a part of the suction pipe (1) to the cleaning waste liquid recovery tank (12) with a suction hose (15). A switch (35) for operating the electric motor (5), the cleaning liquid supply valve (8) and the vacuum pump (13) is attached near the operation handle (16). The present proposal is a floor cleaning machine having the above structure. When using this, the cleaning liquid supply valve (8) is first turned on to spray the cleaning liquid on the floor surface. Next, the electric motor (5) is turned on and the brush (4) is rotated. Due to the chemical action of the cleaning liquid and the physical action of the rotation of the brush (4), the dirt on the floor is detached and dissolved into the cleaning liquid to become cleaning waste liquid. Next, by turning on the switch of the vacuum pump (13), the cleaning waste liquid recovery tank (12) becomes a negative pressure state. Then, the cleaning waste liquid is collected by the squeegee (14) on the outer periphery of the floor polishing disc (3) by moving the floor cleaning machine, and a negative pressure is applied from the cleaning waste liquid suction port (2) of the suction pipe (1). It is collected by suction in the cleaning waste liquid recovery tank (12). Then, the cleaning waste liquid is collected and the floor surface becomes clean. When moving the floor washer, tilting the floor polishing disc (3) with the operating handle (16) causes the brush (4) in contact with the floor to tilt and the repulsive force of rotation of the brush (4) to be applied. The brush (4) moves in the direction opposite to the rotating direction of the inclined side. When the brush (4) is rotated counterclockwise, tilting it forward moves it to the right, and tilting it backward moves it to the left. Tilt to the left to move forward, tilt to the right to move backward. In this way, it can be moved freely depending on the tilt direction. Also, if the vacuum pump (13) has a very strong suction force, the cleaning waste liquid is sucked even if it is separated from the cleaning waste liquid suction port (2). Is also good. Further, the suction pipe (1) surrounding the floor polishing disc (3) does not necessarily have to be squarely surrounded, and even if it is circularly surrounded, the same function is achieved. Further, in general, when performing floor cleaning, the floor cleaning direction is determined and the cleaning is performed without the suction pipe (1) on the advancing direction side of the cleaning machine, as shown in FIG. , The suction pipes (1) installed in the other three directions can suction without leakage. Therefore, the suction pipe (1) that surrounds the floor polishing disc (3) can be used only in three directions other than the advancing direction of the washing machine in the front, rear, left, and right directions when the washing direction of the washing machine is constant. Just surround it.

[0097]

[Effect of device]

 Therefore, there are the following effects. (B) Since the floor cleaning machine of the present invention can perform floor cleaning while moving freely back and forth and left and right, floor cleaning can be performed cleanly even in a narrow area where the floor cleaning machine of the present invention can enter. Further, since the height of the floor cleaning machine can be lowered by changing the inclination of the support rod (17), the floor cleaning machine can be made to enter a narrower area. (B) Since the suction pipe (1) for sucking the cleaning waste liquid completely surrounds the outer circumference of the floor polishing disc (3), the cleaning waste liquid does not scatter to the outside of the floor cleaning machine and the conventional floor cleaning is performed. Unlike the machine, it is possible to wash every corner of the floor without the need to consider making the squeegee (28) longer in order to prevent scattering of the washing waste liquid that occurs when the direction is changed. (C) Since the floor washer can be moved by the power of the floor polishing electric motor (5), it is no longer necessary for the operator to push the floor washer when cleaning the floor, which makes the work much easier. (D) Since an electric motor for traveling is not required, it is lightweight and easy to carry.
