DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric floor polisher having a detergent injection mechanism.

In a conventional electric floor brushing machine C having a detergent injection mechanism, a brush base 5 having a driving machine 3 mounted on a base 2 and a brush 4 planted thereon is fixed to a brush plate mounting bracket 6, as shown in FIG. A brush plate mounting bracket 6 is coupled to a drive shaft 7 of the drive unit 3 and rotated. A detergent supply hole 5a is formed in the brush base 5 and a detergent pipe 22 is inserted through the base 2. Then, the detergent 23 from a detergent tank (not shown) provided on the base 2 is dropped from the detergent pipe 22 onto the upper surface 5b of the brush base 5 by an electric floor polisher C having a detergent injection mechanism. 5
The detergent 23 was dropped on the floor 8 through the a and washed with the brush 4 on the floor 8.

[0003]

However, in the electric floor polisher C having the above-described conventional detergent pouring mechanism, since the brush base 5 is actually rotating, it falls on the upper surface 5b of the brush base 5. The detergent 23 does not pass through the detergent supply hole 5a, flows on the upper surface 5b of the brush base 5 due to centrifugal force, scatters from the outer periphery of the brush base 5 to the outside, and does not flow down to the floor 8 which is actually brushed by the brush 4, and in some cases, The detergent 23 scatters on the wall surface and stains the wall surface. In particular, in recent years, the rotation of the brush base 5 is increased in order to increase the cleaning efficiency of the electric floor polisher having a detergent injection mechanism, so that the detergent 23 is more easily scattered. For this reason, a rubber plate is provided on the outer circumference of the base 2 to
There are products that prevent splattering, but brush 4
As a result, the cleaning efficiency is poor because the detergent 23 does not flow down on the floor 8 which is actually polished.

Accordingly, the present invention has been made in view of the above circumstances, and an electric motor having a detergent injecting mechanism capable of increasing the cleaning efficiency by flowing a detergent onto a floor surface or a central portion inside the floor surface which is actually polished by a brush. There is a problem in trying to make it a floor polisher.

SUMMARY OF THE INVENTION The present invention has been developed to solve the above-mentioned problems. A drive is mounted on a base, a brush plate mounting bracket is fixed to the drive, and the brush is mounted on the base. In an electric floor polisher in which a plate mounting bracket is connected and rotated and a detergent is injected into the brush plate mounting bracket, a pressing rod 31 is provided in the gear box 13 of the driving machine 3 in the brush plate mounting bracket 6; A ring-shaped metal plate 32 and a sponge-like sponge body 33 are provided, attached to the pressing rod 31 so that the distance to the plate 32 can be adjusted, and the sponge body 33 is placed below the plate 32. A plurality of pressing rods 3 having different lengths which do not rotate with the rotation of the brush plate mounting bracket 6 in which the foaming machine 30 is provided. a, 31b, the sponge body 3 to fairly Kai take with the rotation of the brush plate mounting bracket 6
The present invention is to provide an electric floor polisher having a detergent injection mechanism characterized in that the detergent 23 supplied to the sponge body 33 is foamed or atomized by pressing or restoring 3.

[0006]

According to the electric floor polisher having the above-described detergent pouring mechanism, the detergent passing through the detergent pipe on the base falls into the brush plate mounting bracket, and the detergent is supplied from the detergent supply hole formed in the brush plate. The detergent flows down onto the floor located inside the brush without splattering from the outer periphery of the base or onto the floor currently being brushed by the brush due to the centrifugal force caused by the rotation of the brush plate mounting bracket, and the detergent immediately Will be involved in cleaning.

[0007] The detergent dropped into the brush plate mounting bracket is foamed by the foaming machine, and the foamed detergent is actually seen by the floor or the brush positioned inside the brush from the detergent supply hole. Run down on the floor.

[0008] Further, the detergent dropped into the brush plate mounting bracket is sucked into the sponge, and is loosely fitted to the drive shaft by the pressing rod fixed to the case of the non-rotating driving machine, and is rotated by the rotation of the brush plate mounting bracket. The entraining plate is moved up and down, and the movement of the plate squashes and restores the spongy body up and down to foam the detergent.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a detergent injection mechanism and a foaming machine 3 of the present invention.
1 is a sectional view showing an electric floor polisher provided with a zero. In this figure, an electric floor polisher B having a detergent injection mechanism comprises an electric floor polisher 1 and a detergent injection mechanism 20 incorporated therein, and the electric floor polisher 1 has a drive unit 3 attached to a base 2 and a brush. The brush base 5 on which the brush 4 is planted is fixed to a brush plate mounting bracket 6, and the brush plate mounting bracket 6 is connected to a drive shaft 7 of the driving machine 3 and rotated.

The base 2 has a bottomed cylindrical body and has a hole 11 at the center of the bottom surface 10, and the driving device 3 is fitted into the hole 11. The drive unit 3 is configured by mounting a gear box (case) 13 below a motor 12.
The rotation speed of the drive shaft 7 of the gear box 13 is made appropriate.

The brush 4 is formed by bundling dozens of synthetic resin bristles into a bunch and planting a large number thereof on a ring-shaped brush base 5. Since the brush 4 is planted in a donut shape on the brush base 5, the floor 8 located inside the brush 4 when the electric floor polisher 1 is placed on the floor 8 is surrounded by the brush 4. It will be in a state like it has been.
In general, the brush base 5 is often made of wood. In this case, a metal brush plate 14 is attached, and a brush plate mounting bracket 6 is detachably screwed to the brush plate 14. The brush plate mounting bracket 6 is provided with a foaming machine 30.
The foaming machine 30 is provided with a pressing rod 31 in a gear box (case) 13 of the driving machine 3, and further, a driving shaft 7 of the driving machine 3.
The brush 32 is provided in the brush plate mounting bracket 6 in a loosely fitted state with the plate 32 up and the sponge body 33 down. There are two pressing rods 31a and 31b, which are threaded.
3 is screwed 180 degrees away from the mounting piece 34 fixed to 3 so that the distance to the plate 32 can be adjusted. The plate 32 has a metal ring shape, and one of the sponges 33 is also a sponge and has a ring shape. These plate 32 and spongy body 33 are
As described above, since the brush plate mounting bracket 6 is loosely fitted to the drive shaft 7 and housed in the brush plate mounting bracket 6, it is rotated along with the rotation of the brush plate mounting bracket 6, and has a different pressing length. The sponge body 33 is pressed or returned by the rods 31a and 31b. For this reason, the detergent 23 supplied to the sponge body 33 can be made into a foamed or mist-like detergent with a small amount of water.

The detergent injecting mechanism 20 has a detergent supply hole 21 formed in the brush plate mounting bracket 6 and a detergent supply pipe 24 penetrated through the base 2.
The detergent 23 is introduced into the brush plate fitting 6 to supply the detergent 23 to the brush 4 from the detergent supply hole 21. The detergent supply holes 21 are provided on the side wall 6a and the bottom plate of the brush plate mounting bracket 6, respectively.
Since these detergent supply holes 21 are located inside the brush 4, the detergent supply holes 21 are supplied to the inside of the brush 4 or to the brush 4 even when the brush plate mounting bracket 6 rotates. The detergent supply pipe 24 uses at least a square pipe between the gear box (case) 13 and the brush plate 14. The reason is the gear box (case) 1
Although the gap between the brush plate 3 and the brush plate 14 is usually narrow and a round pipe cannot provide a sufficient pipe cross-sectional area, the flow rate is insufficient. However, a square pipe can be sufficiently long in the width direction even if the gap is small, and the pipe cross-sectional area can be increased. This is because a large flow rate can be obtained.

Next, a method of using the electric floor polisher B having the above-described detergent injection mechanism will be described. First, the electric floor polisher 1 having the detergent injection mechanism 20 is carried on the floor 8 to be polished, the supply cock of the detergent tank is closed, and the prepared detergent 23 is put into the detergent tank. Next, the power is turned on, the motor 12 of the driving machine 3 is rotated, and simultaneously the supply cock is opened to supply the detergent 23 to the detergent supply pipe 24. The supplied detergent 23 passes through the detergent supply pipe 24 and enters the brush plate fitting 6 in which the foaming machine 30 is provided. Since the brush plate mounting bracket 6 rotates together with the brush 4, the detergent 23 flows toward the side wall 6 a by centrifugal force, and drops from the detergent supply hole 21 to the floor 8 or the brush 4 inside the brush 4. The floor 8 is cleaned by the rotating brush 4. The floor 8
When the cleaning is completed, the supply cock of the detergent tank is closed, the power is turned off, the motor 12 is stopped, and the operation is completed.

In the above-described embodiment, the detergent pouring machine 20 in which the foaming machine 30 of the present invention is installed is attached to a conventional electric floor brushing machine C. Further, the mechanism of the present invention can be easily attached to the existing electric floor polisher C.

[0015]

As described above in detail, according to the electric floor polisher having the detergent injection mechanism of the present invention, the detergent that has passed through the detergent pipe on the base falls into the brush plate mounting bracket, and further drops. Detergent flows from the perforated detergent supply hole to the floor located inside the brush without scattering from the outer periphery of the base to the outside, or the floor that is currently being seen by the brush due to centrifugal force caused by rotation of the brush plate mounting bracket. The detergent that runs off the surface will immediately participate in cleaning the floor. Therefore, the detergent flows down to the floor or the inner central part of the brush which is actually being polished by the brush, and the detergent is used without waste to increase the cleaning efficiency. Further, the detergent is not scattered to the outside and the wall surface and the like are not stained. In addition, a conventional electric floor polisher can be easily modified and used.

Further, the detergent dropped into the brush plate mounting bracket is foamed by the foaming machine, and the foamed detergent is actually seen by the floor or the brush positioned inside the brush from the detergent supply hole. Run down on the floor. Therefore,
In addition to the above effects, the detergent can be foamed to reduce the amount of water and can be sent to a symmetrical object such as a floor to be cleaned, so that carpets as well as the floor surface can be efficiently cleaned without much wetting.

Further, the detergent dropped into the brush plate mounting bracket is sucked into the sponge, and the plate loosely fitted to the drive shaft by the pressing rod fixed to the case of the driving machine which does not rotate due to the rotation of the brush plate mounting bracket. The plate is moved up and down, and the movement of the plate crushes and restores the marine body in the up and down direction to foam the detergent. Therefore, in addition to the above-described effects, a foaming machine having a simple structure can be used to efficiently generate foam, and a conventional electric floor polisher can be modified and used.
