Abstract

PURPOSE:To lighten load on a sliding portion, to reduce noise and to improve the durability of a brush unit by providing a clearance gap between the forward end of a brush unit disposed on the peripheral surface of a washing rotor and a washing table. CONSTITUTION:Washed material 27 is fed out in the direction of an arrow (d) by rotation [direction of an arrow (c)] of a washing rotor 13. In order to wash a washed material, the washed material 27 is stopped in such a manner as to be against the rotation of the washing rotor 13, or moved in the direction of an arrow (e). At this time, the washed material 27 in a sliding surface like recess portion 20 is pushed in the direction of an arrow (a) by both ends of the sliding surface like recess portion 20. Accordingly, a clearance gap (b) provided between a brush unit 14 provided on the washing rotor 13 and the sliding surface like recess portion 20 is about 0.5mm because even if it is larger than the thickness of the washed material 27, there is no obstacle to washing performance. Accordingly, except the washing time, pressure on the brush unit 14 is not produced thanks to the clearance gap so as to prevent falling of bristles and generate no sliding noise due to absence of washed material.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a spot washing device for removing stains from spots such as sleeves and collars of clothing.

BACKGROUND OF THE INVENTION Conventionally, stains on sleeves, collars, and other parts of cutter shirts and the like are difficult to remove, so the practice has been to wash those parts by hand using a brush or the like, and then toss them in a washing machine.

However, since the workability of this spot washing is very poor, the present inventors have proposed a spot washing device that efficiently carries out spot washing of sleeves, collars, etc. Its configuration is shown in FIGS. 6 and 7. That is, the brush body 2 is provided on the surface of the rotating body 1 for cleaning, so that the rotating body 1 for cleaning can be rotated in the direction indicated by the arrow. Further, a sliding surface recess 4 is provided in a part of the washing table 3, and when an object to be cleaned (not shown) is inserted into the end surface 6 of this sliding surface recess 4, the object to be cleaned will move along the sliding surface recess 4. sent out.

Here, the rotational force of the motor 7 provided in the main body 6 is transmitted to the cleaning rotary body 1 via the speed reduction mechanism 82 and the rotating shaft 9, and the cleaning rotary body 1 is rotationally driven. Further, a washing table upper frame 10 constituting the washing table 3 is arranged so that the brush body 2 is pressed against the sliding surface recess 4;
A spring 12 was disposed between the washing table bottom plate 11 and the washing table bottom plate 11.

Problems to be Solved by the Invention However, in such a conventional configuration, since the brush body 2 is always pressed against the sliding surface recess 4, the bristles of the brush may fall off, or the sliding surface may be damaged during rotation. The friction with the recess 4 generates sliding noise, and the torque to the motor 7 connected to the cleaning rotor 1 increases, causing the meshing noise of the gears (not shown) of the reduction mechanism. It had the problem of increasing demand. In addition, the motor specifications are affected by the increased torque due to the brush sliding resistance of the motor 7, which increases costs, and furthermore, there are issues with the durability of the brush bristles and sliding surface recesses due to friction. Ta.

Further, even after use of this partial cleaning device, the bristles of the brush are constantly subjected to the pressing force of the washing table, so that the bristles remain curly.

The first object of the present invention is to reduce the load on the sliding parts to realize noise reduction and to improve the durability of the brush body. In addition, the second purpose is to prevent deformation of the brush body.
The purpose of

Means for Solving the Problems The first technical means for achieving the above object consists of a main body having a motor and a speed reduction mechanism, a cleaning rotary body rotated by a rotating shaft of the main body, and a cleaning rotary body that is rotated by a rotating shaft of the main body. The washing table is provided with a cleaning table on which an object to be cleaned can be interposed between the washing table and the washing table, and a gap is provided between the tip of the brush body provided on the circumferential surface of the cleaning rotary body and the cleaning table.

In addition, the second technical means is that in a storage box that houses a main body that houses a rotary drive unit, the washing stand is configured to press against the circumferential surface of the washing rotary body through an elastic material, and the washing table is configured to press against the circumferential surface of the washing rotary body through an elastic material. is provided with a groove so that it can slide freely on the ribs on the inner surface of the storage box, and when it is stored in the storage box, the rib comes into contact with and slides against the top surface of the washing table, so that the peripheral surface of the cleaning rotating body and the washing table are The configuration is such that the two are separated from each other.

Effect In the first technical means described above, since a gap is always provided between the tip of the brush body of the cleaning rotary body and the cleaning table, the brush body is not pressed against the cleaning table, and there is a risk that the bristles may become loose. It disappears. In addition, since the brush body and the cleaning table do not touch each other at the beginning of rotation, there is no friction and no sliding noise occurs, and the motor connected to the cleaning rotating body does not have any increased torque due to friction. , the motor torque can be reduced.

In the second technical means, when in use, the washing stand is pressed against the washing rotating body by the elastic material, but when the main body, the washing rotating body, and the washing stand are stored in the storage box, Since the provided rib body pushes the washing table downward, the cleaning rotating body and the washing table can be separated and a gap is created, so the brush body of the cleaning rotating body is not pressed against the washing table, and the brush body when stored. It is possible to prevent the body from sagging. When in use, when objects to be cleaned of different thicknesses are passed through the cleaning rotating body and the washing table due to pressure, the washing table moves according to the thickness of the object to be cleaned, so the object to be cleaned can be moved smoothly. The cleaning performance can be improved by allowing the water to pass through and preventing the occurrence of unwashed areas.

Embodiment A first embodiment of the present invention will be explained with reference to FIGS. 1 to 3. In the figure, 13 is a cylindrical cleaning rotating body, and a plurality of brush bodies 14 are provided on its circumferential surface. The rotational force of a motor 16 provided in a main body 16 is transmitted to the cleaning rotary body 13 via a deceleration mechanism 17 and a rotating shaft 18, and the cleaning rotary body 13 is driven to rotate. Note that power is supplied to the motor 16 via a power cord (not shown). A cleaning table 19 facing the cleaning rotary body 13 is disposed below the cleaning rotary body 13.
A substantially arcuate sliding surface recess 20 along the circumferential surface of the cleaning rotating body 13 is provided in a part of the cleaning table 19. The washing table 19 has a washing table upper frame 2 in which a sliding surface-like substantially concave portion 20 is formed.
1, and a cleaning table bottom plate 22 formed by extending the bottom plate of the main body 15 forward, and the cleaning table bottom plate 22 has screw holes 2.
3, a screw boss 24 is provided on the back surface of the washing table top frame 21 facing this hole 23, a spring 26 is arranged between the hole 23 and the boss 24, and the washing table top frame 21 is rotated in eight directions. I try to push it. In addition, the brush body 14 and the sliding surface-like substantially concave portion 20
The height is adjusted using screws 26 so that there is a gap b (about o, sw) between them.

According to the above configuration, the object to be cleaned 27 is sent out in the direction of arrow d by the rotation of the cleaning rotary body 13 (direction C).

In order to clean the object to be cleaned, the object to be cleaned 27 is stopped so as to oppose the rotation of the cleaning rotary body 130, or is moved in the direction of arrow e as shown in the figure. This is the object to be cleaned 27
This is to improve the cleaning effect by increasing the number of times the brush body 14 comes into contact with the brush body 14 or by increasing the frictional force. At this time, since the object to be cleaned 27 is pulled at both ends, the object to be cleaned 27 located in the sliding surface-like substantially concave portion 20 is pushed in the direction C by both ends of the sliding surface-like substantially concave portion 20 . Therefore, even if the gap is thicker than the thickness of the object to be cleaned 27, the cleaning performance will not be affected.
Leave a gap of about 1 inch.

Therefore, since it is possible to leave a gap between the brush body 14 and the sliding surface-like substantially concave portion 2o, there is no pressure on the brush body 14 due to the gap at times other than cleaning, and it is possible to prevent the brush bristles from sagging. , there is no sliding noise when there is no object to be cleaned,
Furthermore, the motor torque does not increase due to friction, and it becomes possible to reduce the motor torque by the amount of increase.

Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 6. Grooves 28 are provided on both sides of the main body 16.
The lower surface of 8 is located below the upper surface of the washing table 19 (the upper surface of the washing table upper frame 21) and serves as a relief groove for a rib body 30, which will be described later. The main body 16, the cleaning rotating body 13, and the cleaning table 19 are movable in the front-back direction and are housed in a storage box 29. A rib body 30 is formed on the inner surface of the storage box 29, and the groove 28 in the main body is a relief groove. When storing the main body 16 etc. in the storage box 29, the rib body 30 is made into a substantially rectangular shape so that the rib body 3o can freely slide in contact with the top surface of the cleaning table 18, and the rib body 3o touches the top surface of the cleaning table 19. It makes it possible to suppress.

In the above configuration, except when stored, the brush body 14 of the cleaning rotary body 13 is attached to the spring 26 as shown in FIG.
The screw 26 is adjusted so that it is pressed by the sliding surface-like substantially concave portion 2o. When stored, the upper surface of the washing table 19 is pushed in the direction f by the rib body 30, so that a gap g is created between the brush body 14 and the sliding surface-like substantially concave portion 2o. At this time, the gap g
In order to create this, the lower surface of the groove 28 is positioned about the dimension g below the upper surface of the washing table 19 as a rib relief. As described above, when the brush body is stored, there is a gap between the brush body 14 and the sliding surface-like substantially concave portion 20, so that the brush bristles can be prevented from falling down. Further, during cleaning, since the brush body 14 is pressed against the sliding surface-like substantially recessed portion 20, when the object to be cleaned 27 having a different thickness is passed through the cleaning rotary body 13 and the sliding surface-like substantially recessed portion 20, cleaning Since the table 19 moves according to the thickness of the object to be cleaned 27, the object to be cleaned can be passed through smoothly, and the occurrence of unwashed parts can also be prevented, thereby improving cleaning performance.

Effects of the Invention As is clear from the above embodiments, according to the present invention, since a gap is always provided between the tip of the brush body of the cleaning rotating body and the cleaning table, no pressure is applied to the brush body except during cleaning. Since no pressure is applied, the time required to apply pressure to the brush bristles is shortened, and there is no risk of brush bristles becoming loose. In addition, the hardness of the bristles can be made weaker, reducing the amount of damage to the cloth of the object to be cleaned. In addition, since the brush body and the washing table are not in contact with each other in the initial stage of rotation, there is no friction and no sliding noise is generated, and the torque of the motor can be reduced because the torque increase due to the friction of the brush bristles is eliminated. Furthermore, it also has the effect of reducing noise by reducing the meshing sound of the gears of the reduction mechanism.

In addition, since there is a gap between the tip of the brush body and the washing table when storing it in the storage box, the time required to suppress the brush bristles is shortened, and it is possible to prevent the bristles from folding without increasing the hardness of the bristles. Furthermore, during use, the washing table suppresses the object to be cleaned against the cleaning rotary body, so even if objects with different thicknesses are passed between the cleaning rotary body and the cleaning table, the cleaning table does not allow the Since it moves according to the current, the object to be cleaned can pass through it smoothly, and it is also possible to prevent the occurrence of unwashed parts, improving cleaning performance. Furthermore, even if the length of the brush bristles changes due to abrasion of the bristles during cleaning, the brush bristles are still pressed, so there is no problem with the cleaning performance.
