BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in the technical field of a floor scrubber (scrubber) for cleaning a floor surface with a rotating brush while running, and more specifically, a floor scrubber. The present invention relates to an improvement of an operation switch device suitable for use in a vehicle.

[0002]

2. Description of the Related Art As shown in Japanese Utility Model Application Laid-Open No. 2-112242, for example, a conventional general floor cleaning machine rotates a rotary brush while supplying cleaning water contained in a tank to a rotary brush by a pump. The brush is rotated by a motor to wash the floor, and the washed sewage is suction-collected to a sewage tank by applying a suction action of a blower to a squeegee. As described in Japanese Patent Application No. 4-164004, for example, the pump, the motor, and the blower are turned on / off in the operation unit.
A switch for FF operation is provided, and a pump, a motor and a blower are controlled and operated according to the operation of these switches to clean the floor.

[0003]

In the cleaning of the floor surface, the pump, the motor, and the blower are all operated to perform the normal operation of cleaning the floor surface and sucking sewage. There are three types of operation: a cleaning operation in which only the floor is washed without suctioning the squeegee, and a suction operation in which only the suction of the sewage is performed without cleaning the floor. Each switch is operated according to the situation of the site, and one of these three types of operation is selected to proceed with the operation. However, during normal operation, the pump, motor, and blower are all set to three switches respectively. Need to operate,
In addition, in the case of the washing operation in which only the floor surface is washed, it is necessary to operate two switches, a pump and a motor, respectively, so that the switch operation is very complicated, and each operation is started and stopped. Since it is sometimes necessary to repeat the ON / OFF operation of these switches, there is a case where the complexity is further increased and the operation may be erroneously performed.

[0004] Therefore, the technical problem of the present invention is the above-mentioned 3
An object of the present invention is to make it possible to easily select a type of cleaning operation by a single switch operation.

[0005]

Means taken by the present invention to solve the above technical problems are as follows. In a floor surface washing machine configured to rotate a rotating brush with a motor while supplying washing water with a pump to wash the floor surface, and apply a suction action of a blower to a squeegee to suck sewage after washing,

(1) A first switch for simultaneously operating a water supply pump, a rotary brush motor and a squeegee blower, and a water supply pump and a rotary brush are provided in the operation unit of the floor washer. A second switch for operating only the motor and a third switch for operating only the blower for the squeegee are provided, and these switches are selectively operated by a select switch.

(2) The switches selected and operated by the select switches include an OFF switch for stopping the operation of any of a water supply pump, a rotary brush motor, and a squeegee blower.

[0008]

The above means operates as follows. The above (1)
According to the means described in the above, the first switch is operated by the select switch.
When the switch is selected, all of the pump, motor and blower operate to supply cleaning water, clean the floor with a rotating brush, and suction sewage with a squeegee.
When the second switch is selected by the select switch, only the supply of the cleaning water and the cleaning of the floor surface by the rotating brush are performed.
Further, when the third switch is selected, only the suction of the wastewater can be performed, so that the above three types of cleaning operations can be performed with only one switch operation, respectively, thereby greatly simplifying the switch operation. To

According to the means described in the above (2), when the OFF switch is selected by the select switch, the operation of any of the pump, the motor and the blower can be stopped. And then
It is possible to simplify the switch operation. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
