Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor cleaning suction device for cleaning a floor surface and sucking water by connecting to a water suction type vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, floor cleaning of linoleum, tiles, etc. is performed with a polisher having a rotating brush that is sprinkled with water and a cleaning agent and driven by a motor, and then a water-absorbing vacuum cleaner or water-suction can be used. The wet and dry type vacuum cleaner absorbs dirty water after cleaning to clean the floor. In addition, there is a floor cleaning machine which has a rotating brush for cleaning driven by a motor and a water suction nozzle for a large-sized machine to clean the floor surface and suck water.

[0003]

In order to clean the floor surface with such conventional equipment, except for a large floor cleaning machine suitable for a wide range such as a factory, it is necessary to clean the floor surface of a general store or the like. I was forced to use both a polisher and a water suction type vacuum cleaner, and I needed two types of equipment, which was troublesome to use and was difficult to store. Therefore, it is conceivable to integrate a polisher mechanism having a rotating brush for cleaning driven by a motor into the water suction nozzle of the water suction type vacuum cleaner, but the power cord of the motor for the polisher is wired along the suction hose. Then, you have to connect it to the outlet of the vacuum cleaner body, and replace the nozzle part at the tip of the suction hose to perform wet (water suction) and dry (normal dust suction) like a wet and dry type vacuum cleaner. In this case, the power cord wiring, connection, and disconnection are bothersome in use, and the power cord of the vacuum cleaner body is made thicker and has a large current capacity, and the specifications of the vacuum cleaner body are expensive. There was a problem that it became something like that.

The present invention is intended to solve the above-mentioned problems, and can be connected to a water suction type vacuum cleaner such as a wet-and-dry type vacuum cleaner to clean the floor surface and suck water without using a motor. A first object is to provide a floor cleaning suction tool which is simple and inexpensive.

A second object is to prevent the floor cleaning suction tool from swaying left and right by the cleaning rotating brush when the force pushing the floor surface during cleaning is weakened.

The third and fourth objects are to make it possible to select between cleaning and water suction, and to make this selection automatic.

[0007]

SUMMARY OF THE INVENTION In order to achieve the first object of the present invention, a floor cleaning suction tool is connected to a water suction type vacuum cleaner, and the rotation of a turbine rotated by a suction air flow is reduced by a speed reducer. The first problem solving is that the turbine drive suction flow path transmitted to the rotary brush via the flow path and the water suction nozzle flow path that is provided with this rotary brush communicate with each other to perform cleaning of the floor surface and water suction. As a means.

Below the floor cleaning suction device, a plurality of rollers that rotate in the front-rear direction are urged toward the floor surface so that a plurality of rollers are provided so that the rotating brush does not come into contact with the ground due to the weight of the floor cleaning suction device. This is the second means for solving the problem.

A third means for solving the problems is to selectively select the turbine drive suction passage and the water suction nozzle passage.

Further, a valve body is interposed between the turbine driving suction flow passage and the water suction nozzle flow passage, and a weight body is connected to the valve body to hold it vertically so that the main body is tilted. According to the fourth problem solving means, the valve body automatically selects both flow paths.

[0011]

According to the first means for solving the above problems, the present invention provides:
By connecting to a water suction type vacuum cleaner such as a wet and dry type vacuum cleaner, the floor surface can be cleaned and water can be sucked in, and an easy-to-use and inexpensive floor cleaning suction tool can be provided without using a drive motor. it can.

Further, according to the second means for solving the problems, when the force for pushing the floor surface is weakened during the cleaning work, the floor cleaning suction tool is levitated by the roller arranged so as to be biased toward the floor surface side.
That is, since the rotary brush is separated from the floor surface, it is possible to prevent the floor cleaning suction tool from swaying to the left and right by the cleaning rotary brush, and facilitate the cleaning operation.

With the third means for solving the problems, cleaning and water suction can be selected, and each can be driven with full power, enabling careful floor cleaning and water suction, and using a cleaning brush with a cleaning agent. Also, it will not be sucked in from the nozzle portion before it contributes to the cleaning of.

Further, according to the fourth means for solving the problems, when the rotating cleaning brush of the floor cleaning suction tool body is grounded on the floor surface, it is interposed between the turbine drive suction passage and the water suction nozzle passage. Then, the water suction nozzle flow path is closed by the valve body vertically connected with the weight body to perform floor cleaning, and the floor cleaning suction tool body is tilted to separate the rotary cleaning brush from the floor surface. The valve body can automatically close the turbine driving suction flow passage and open the water suction nozzle flow passage to suck water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the floor cleaning suction tool body 1
A main body cover 2 is arranged above the main body 1 (hereinafter referred to as the main body 1), and a turbine chamber 4 and a mechanism chamber 5 are formed with a partition plate 3 interposed. A turbine 7 fixed to a rotating shaft 6 is provided in the turbine chamber 4, and a suction airflow 9 from an intake port 8 is guided to a turbine 7 through a turbine nozzle 10 to form a partition plate 3
The suction passage 13 for driving the turbine is formed through the ventilation port 11 to the connection pipe 12. Further, inside the mechanism chamber 5, a speed reducer 15 extending from the pinion 6a formed on the rotary shaft 6 to the output shaft 14 is installed. A rotary brush 17 for floor cleaning is attached to the output shaft 14 with a set screw 16. It should be noted that it is possible to arrange a plurality of output shafts 14 from the speed reducer 15 and provide a plurality of rotating brushes 17.
A bumper 18 made of rubber, soft vinyl chloride, or the like is attached to the lower portion of the main body 1 so as to enclose the rotating brush 17 with a skirt portion 18a. The skirt portion 18a is a buffer member for preventing the scattering of dirty water by the rotating brush 17. Behind the rotating brush 17, a water suction nozzle 2 having a rubber lip 19 grounded on the floor surface
0 is attached. The upper communication hole 21 forms a water suction nozzle passage 22 that reaches the connection pipe 12, and joins with the turbine driving suction passage 13. Further, below the main body 1, there is a roller 23 that rotates in the front-back direction.
A plurality of springs are arranged on the floor side by being urged by the compression springs 24, and the rotating brush 17 is floated by the weight of the floor cleaning suction tool so as not to come into contact with the ground. The floor cleaning suction device is shown in FIG.
As described above, it is connected to a water suction type vacuum cleaner such as a wet and dry type vacuum cleaner 25 through the suction hose 26, the joint pipe 27 and the extension pipe 28 at the connecting pipe 12 portion for use. 29 is a switch.

In the above construction, when the wet and dry cleaner 25 is driven by the switch 29, the turbine 7 is rotated at a high speed by sucking air from the turbine driving suction passage 13 and the water suction nozzle passage 22. The rotating brush 17 is rotationally driven via the speed reducer 15 to wash the floor surface, and the water suction nozzle 20 sucks dirty water from the floor surface.

Further, when the force pushing the floor surface is weakened during the cleaning work, the floor cleaning suction tool is levitated by the roller 23 urged to the floor surface side, that is, the rotary brush 17 is lifted from the floor surface. Since they are separated from each other, it is possible to prevent the floor cleaning suction tool from rocking to the left and right by the rotating brush 17, which facilitates cleaning work.

3 and 4 show another embodiment of FIG.
The same members as are indicated by the same reference numerals. In FIG. 3, a valve element 32 pivotally supported by a rotary shaft 31 is provided between the communication hole 30 on the turbine driving suction flow path 13 side and the upper communication hole 21 of the water suction nozzle flow path 22, and the operation lever 33 is provided. By both communication holes 2
1 and 30 are selected alternatively. When the valve element 32 closes the communication hole 21 as shown in the figure, the turbine 7 is rotated at a high speed by the turbine-driving suction passage 13, and the rotary brush 17 is rotationally driven to clean only the floor surface. When the communication hole 21 is opened and the communication hole 30 is closed by operating the operation lever 33 as shown by the chain double-dashed line in the figure, the water suction nozzle passage 22
Only the sewage on the floor is sucked from the water suction nozzle 20. Therefore, cleaning and water suction can be selected, and each can be driven at full power, enabling careful floor cleaning and water suction, and when using a cleaning agent, the water suction nozzle does not contribute to cleaning with the rotating brush 17. It will not be sucked in from the 20th copy.

Further, in FIG. 4, the communication hole 30 on the suction drive suction passage 13 side and the water suction nozzle passage 22 are provided.
A valve body 35 pivotally supported by a rotary shaft 34 is disposed between the rotary body 34 and the upper communication hole 21 of the weight body 36. The weight body 36 is always in a vertical posture with respect to the floor surface 37 due to gravity. The rear rollers 38 are arranged at both sides of the water suction nozzle 20 so that the rubber lip 19 does not separate from the floor surface 37 even if the main body 1 is inclined at an angle θ with respect to the floor surface 37 as shown in the figure. Then, when the main body 1 is inclined by the angle θ with respect to the floor surface 37 as in the illustrated state, the rotary brush 17 is separated from the floor surface 37, and the valve body 3
5 closes the communication hole 30, the rotary brush 17 is stopped,
On the other hand, the communication hole 21 is opened and the water suction nozzle channel 2 is provided.
2 only sucks sewage from the floor from the water suction nozzle 20. Further, when the inclination of the main body 1 is returned to the original state and the rotary brush 17 is grounded to the floor surface 37, the weight body 36
Is in a state shown by a two-dot chain line in a vertical posture with respect to the floor surface 37, that is, with respect to the ground surface of the rotating brush 17 in the figure,
The valve body 35 closes the communication hole 21 and opens the communication hole 30, the turbine 7 is rotated at high speed, and the rotary brush 17 is rotationally driven to clean only the floor surface. Therefore, the floor cleaning by the rotating brush 17 and the suction of the dirty water on the floor by the water suction nozzle 20 can be automatically selected by the tilting operation of the main body 1. Further, in the inclination range of the angle θ, the valve body 35 opens both the communication holes 30 and 21, and the flow rates of the turbine drive suction passage 13 and the water suction nozzle passage 22 are changed according to the inclination angle, that is, the inclination. The smaller the angle θ is, the greater the cleaning force of the floor surface by the rotating brush 17 is. On the contrary, the larger the inclination angle θ is, the greater the suction force of the floor surface from the water suction nozzle 20 is.

[0021]

As is apparent from the above embodiments, according to the present invention, a floor surface can be cleaned and water can be sucked by connecting to a water suction type vacuum cleaner such as a wet and dry type vacuum cleaner.
It is possible to provide an easy-to-use and inexpensive floor cleaning suction tool without using a drive motor, and it is possible to expand the versatility and convenience of this type of vacuum cleaner.

Further, when the force pushing the floor surface is weakened during the cleaning work, the floor cleaning suction tool is levitated by the roller arranged so as to be biased toward the floor surface, that is, the rotary brush is separated from the floor surface. Therefore, it is possible to prevent the floor cleaning suction tool from rocking to the left or right by the rotating cleaning brush.
The cleaning work can be facilitated.

The cleaning and the water suction can be selected and can be driven with full power respectively, which enables careful floor cleaning and water suction, and when the cleaning agent is used, it contributes to the cleaning by the rotating brush before the nozzle. It will not be sucked in from the department.

Further, when the cleaning rotary brush of the floor cleaning suction tool body is grounded to the floor surface, the weight brush is connected by being interposed between the turbine drive suction flow path and the water suction nozzle flow path. The vertically held valve body closes the water suction nozzle flow path to perform floor cleaning, and the floor cleaning suction tool body is tilted to separate the rotating cleaning brush from the floor surface, and the valve body automatically moves to the turbine. Water can be sucked by closing the drive suction flow passage and opening the water suction nozzle flow passage.
