Description

The present invention relates to a scrubber for cleaning a floor surface with a cleaning brush, a polisher for polishing a floor surface with a pad, or a sweeper for cleaning dust on a floor surface. Used in the technical field of various self-propelled floor cleaning machines (hereinafter collectively simply referred to as floor cleaning machines), specifically, a function of displaying various cleaning data and an external output function. The present invention relates to a floor cleaning machine provided with:

[Conventional technology]

Conventional floor cleaning machines have all been operated by relying on the driver's (operator's) feeling. However, in order to improve the driver's convenience and simultaneously accurately grasp the quality and quantity of work, As a result, floor cleaning machines that display the following data have been developed.

Operating speed (hours).

For battery-operated cleaners, the battery voltage.

Grounding strength of brushes, pads, etc. (current value of power motor required for cleaning).

For floor scrubbers, the amount of clean water or detergent solution and the amount of sewage.

Driving hours of the day.

The mileage of the day.

The above data display is necessary for safety and quality of cleaning, the data display is necessary for the machine to perform sufficiently, and the data display is the most important for cleaning work. It is a display. Further data display
For example, in the case of a polisher, the pad is clogged by wax on the floor, so it is necessary to use it upside down, but this is necessary as a guide.

On the other hand, as a cleaning manager, it was conceivable to display the following data in order to improve work efficiency and accurately manage the quantity and quality of work.

A. Total operating hours of the day.

B. Total mileage for the day.

C. Total cleaning area of the day.

D. Total operating time.

E. Total mileage.

F. Distance traveled per hour.

G. Cleaning area per hour.

Of these data displays, ABEF is convenient for knowing the work efficiency, and it is possible to accurately grasp the quantity and quality of work that relied on the conventional feeling, and the data display of D. and E. Necessary for inspection.

[Problems to be solved by the invention]

As described above, the display of each data is important for the driver and the manager, respectively.
In order to simultaneously display A and G on the same screen, a considerably large screen is required, so that it is physically impossible as a display of a floor cleaning machine. Since the data to be displayed is different, there is a problem that displaying all of these data at the same time may hinder the understanding of the data.In particular, the problem is that displaying data beyond necessity for the driver is rather cumbersome and hinders driving. There was also.

In addition, conventional floor cleaning machines have no way of accurately calculating the cleaning area of the day and the cleaning area per hour, which are important for management. There is also a problem that the management work for accurately recording the quantity and quality of the work becomes very complicated, and on the contrary, the work is confused.

Therefore, a technical problem of the present invention is to accurately calculate and display a cleaning area important for management and a cleaning area per time, and switch and display data required by a driver and an administrator on different screens. That is to do.

[Means for solving the problem]

Means taken in the present invention to solve the above technical problems are as follows.

A floor cleaning machine configured to wash, polish or clean a floor surface while traveling by rotating a wheel for traveling and a brush or a pad by a motor, respectively. (1) Rotation of the wheel Wheel rotation number storage means that counts and stores the number in a memory, and a traveling distance calculation means that calculates a traveling distance of the day from the traveling distance when the wheel makes one revolution and the rotation number of the wheel stored in the memory, Cleaning area calculating means for calculating the cleaning area of the day from the running distance calculated by the running distance calculating means and the width of the brush or pad, that is, the cleaning width; and running time measuring means for measuring the running time of the day. , A cleaning area per hour calculating means for calculating a cleaning area per hour of the day from the calculated and measured cleaning area and the running time of the day, and a running of the day calculated by each of these means. Storage means for storing the distance, the cleaning area of the day and the cleaning area per hour of the day in a memory, and display means for displaying such data on a display.

(2) While the driving data for the driver, such as the current traveling speed, the traveling time of the day, and the traveling distance of the day, is configured to be normally displayed on the display, the day of the day calculated by the cleaning area calculating means is calculated. The management data comprising the cleaning area and the cleaning area per hour calculated by the cleaning area per hour calculating means is displayed on the display only when the management-dedicated switch is operated.

[Action]

 The above means works as follows.

According to the means described in the above (1), the cleaning area of the day is calculated by multiplying the cleaning width of the cleaning machine, which is input in advance, by the traveling distance calculated from the outer circumference of the wheel and the number of rotations. It is also possible to calculate the cleaning area per hour of the day by dividing the cleaning area of the day by the travel time of the day determined by the time measurement. The cleaning area and the cleaning area per hour of the day are stored in the memory and displayed on the display, so that both the manager and the worker can grasp the amount of work.

According to the means described in the above (2), operation data necessary for operation such as the current traveling speed or traveling time, and management data necessary for management such as the cleaning area of the day and the cleaning area per hour of the day. By switching the screen and displaying separately, the driver can display only the data necessary for driving to reduce the burden and enable safe driving, while the data necessary for management is only Since the screen can be displayed and the driver cannot switch the screen, it is possible to prevent an unauthorized operation such as falsification or deletion of the management data by the driver.

As described above, the above-described technical problems can be solved by the above-described means, and the problems of the related art can be solved.
