Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a cleaning device used for cleaning floors and the like.

[Conventional technology]

Conventionally available floor cleaning devices are configured to rotate a cleaning material such as a brush, pad, or mop around a vertical axis.

[Problem M that the invention attempts to solve]

However, with a device that rotates the cleaning material around a vertical axis,
If the floor surface is not smooth and has decorative grooves carved into it, not only will it be impossible to remove the dirt, but the dirt may also be pushed into the grooves. In addition, when using a polisher that uses water or liquid detergent to polish the floor surface, it may scatter dirty water around, and the water or liquid detergent used to clean the floor surface may be washed separately. If the dirt is not collected by a collecting means, the dirt will re-adhere to the floor surface when it dries. There are carpet brushes that rotate around a horizontal rotation axis, but if the direction of the brush and the grooves on the floor are aligned, the dirt in the grooves can be removed, but the direction of the grooves and the direction of the brush are not the same. If the brushes are different, it will not be possible to remove the dirt effectively, and dirt will inevitably remain on the floor with lines carved in multiple directions. Must-have. The present invention has been made in view of these points, and its purpose is to provide a cleaning device that can clean not only the surface of the floor, but also the inside of the groove that runs into the floor. .

[Means to solve the problem]

Therefore, the present invention provides a first cleaning member equipped with a cleaning material such as a brush that rotates around a vertical axis, and an outer peripheral surface of the rotating shaft that is visible and bent so as to surround the outer periphery of the first brush. The first feature is that the second cleaning member is provided with a cleaning material such as a brush and rotates around the axis of rotation, and in addition to the front cleaning member, the second cleaning member is provided with a cleaning material such as a brush. The second cleaning member has a second feature in that the second cleaning member includes a vacuum collection means disposed along the rotation axis, and further includes a rotation transmission portion receiving rotational power from the first cleaning member. The third characteristic is that [Function] According to the first feature of the present invention, the first cleaning member cleans a smooth floor surface as before, and the cleaning material of the second cleaning member rotates vertically. In addition to being carried out in-plane, the rotating shaft on which the cleaning material is attached has flexibility and is bent so as to surround the outer periphery of the first cleaning member, so the cleaning is performed in multiple directions on the floor surface. Even if it is worn out, it scrapes out the dirt in these grooves and cleans them thoroughly. According to the second feature, since the vacuum collecting means disposed along the second cleaning member suctions and collects dirt, water, etc., there is no scattering of dirt or water. Yes, 3rd
According to the feature, the second cleaning member can also be driven using the power of the first cleaning member. [Example] The present invention will be described in detail below based on the illustrated embodiment.
and a first cleaning member 1 disposed within. A second cleaning member 2 is provided along the lower periphery of the bouncing member 3, and the first cleaning member 1 has a vertical output shaft that is rotationally driven by a motor 10, as shown in FIG. A large number of brushes 13 are formed to protrude downward from a disc 12 attached to the brush 11. The second cleaning member 2 is a flexible rotary member that is bent annularly along the lower periphery of the housing 3 and is supported by bearings 22 at the ends of a plurality of arms 25 that protrude from the housing 3. shaft 21 and this rotating shaft 21
A geared motor 20 is connected to one end, and brushes 2 are installed radially along the entire length of the rotating shaft 21.
3, the brush 23 is located at a position surrounding the first cleaning member 1 when the geared motor 20 rotates.
rotates in the direction indicated by the arrow in the figure around the annularly bent rotating shaft 21, that is, rotates from the outer periphery of the housing 3 through the downward direction toward the housing 3 side. The brush 23 is attached to the rotating shaft 21 by surrounding the rotating shaft 21 with an elastic body 24 such as raw rubber, and by using the elastic body 24.
This is done by implanting a brush 23 in the 4. The brush 23 may be formed by integrally molding the elastic body 24. In the figure, 30 is a handle whose one end is connected to the housing 3;
31 is a running wheel. However, in the lever cleaning device, the floor surface is cleaned by the rotation of the brush 13 around the vertical axis by the motor 106, and the brush 23 surrounding the brush 13 is rotated vertically by the geared motor 20 while facing in each direction. In order to rotate within a plane, even if there are grooves carved into the floor surface and the direction of these grooves does not match the direction in which the cleaning device is moved,
The dirt that has entered the groove is scraped out by the brush 23. Also, the brush 23 is located on the outer circumferential side of the bouncing 3! Because of this, it is also possible to clean floors and walls. FIG. 3 shows another embodiment. The first cleaning member 1 is formed as a polyurethane with a pad 15 attached to an output shaft 11, and the second cleaning member 2 is formed on a rotating shaft 21.
In addition to the brush 23, there is a spiral rib 25 made of an elastic material.
The vacuum collecting device 4 is attached to the vacuum collecting device 4. The vacuum collection device 4 here includes a suction device 40 attached to the handle 30 and an upper portion disposed along the second cleaning member 2 between the lower peripheral edge of the housing 3 and the second cleaning member 2. It consists of a pipe 41 provided therein and a connecting pipe 42 that connects the two, and the pipe 41 is directed toward the space between the lower peripheral edge of the housing 3 and the second cleaning member 2, as shown in FIG. The groove 43 is provided with a groove 43 that opens. This cleaning device sprays liquid detergent or water on the floor, then
The first cleaning member 1 cleans and polishes the floor surface, and at this time, the second cleaning member 2, especially its ribs 25, prevents the pad 25 of the first cleaning member 1 from rotating within a horizontal plane. This device prevents liquid detergent and water from being scattered around the surrounding area, and at the same time scrapes up the liquid detergent and water along with dirt and dust.
It is sucked up through the stream 43 and collected in a collecting section attached to the suction machine 40. Since the liquid detergent and water do not escape and are collected together with dirt and dust, there is no need to collect the water or liquid detergent with a separate collection device. Furthermore, even if a groove is carved in the floor surface, the tip of the brush 23 of the second cleaning member 2 enters into this groove, so that the bottom part of the cleaner is also reliably cleaned. FIG. 5 shows yet another embodiment. Here, instead of the pipe 41 in the above embodiment, a cover 44 is provided which is attached to the housing 3 airtightly on the inner circumferential side and which covers the second cleaning member 2. The lower periphery of this cover 44 is a skirt 45 made of an elastic material that contacts the floor surface, making the collection of dirt, dust, etc. by the suction device 40 more reliable. Further, at one end of the rotating shaft 21 in the second cleaning member 2, a rotation transmitting portion that engages with a gear portion 17 provided on the outer peripheral surface of the disk 12 of the first cleaning member 1 and rotates the rotating shaft 21 with the rotation of the disk 12. 27 is provided so that the second cleaning member 2 is rotated at high speed by the rotation of the motor 10 of the first cleaning member 1. Incidentally, the vacuum collection device 4 can also be applied to the embodiments shown in FIGS. 1 and 2. Further, in cases where the floor surface has many grooves, the floor surface may be cleaned by operating only the second cleaning member 2.Furthermore, although the second cleaning member 2 is shown here for cleaning the floor surface, In addition, it can also be configured to be used for washing and cleaning vehicle bodies such as automobiles. By attaching the second cleaning member 2 to an existing cleaning device equipped with only the first cleaning member 1, both cleaning members 1
．． 2 may be configured.

【Effect of the invention】

As described above, the first feature of the present invention is that the first cleaning member cleans a smooth floor surface as well as in the past, and that the cleaning material of the second cleaning member rotates. In addition, since the cleaning material is flexible and has a rotating shaft provided on the outer circumferential surface that is bent so as to surround the outer circumference of the first cleaning member, there is a large amount of dirt on the floor surface. Even if there are directional markings, the dirt in these grooves can be scraped out and cleaned, and therefore, it can be easily cleaned regardless of the shape of the floor surface. According to the second feature, in addition to the above points, the vacuum collecting means disposed along the second cleaning member suctions and collects dirt, water, etc. The scattering of dust and water caused by the cleaning member is suppressed by the second cleaning member surrounding the first cleaning member, and at the same time is collected by the vacuum collection means, which makes post-processing easy. Furthermore, according to the third feature, since the second cleaning member can also be rotationally driven by the power of the first cleaning member, no power dedicated to the second cleaning member is required.
It can be provided at low cost.
