Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning machine convenient for cleaning seats of trains, buses, etc., and is capable of performing reliable cleaning regardless of the condition of the surface to be cleaned.

Conventionally, with this type of washing machine, there was no problem when cleaning horizontal surfaces to be cleaned, but detergent could not be fed to vertical surfaces to be cleaned, making it difficult to reliably clean surfaces. It was impossible to clean.

The present invention eliminates such conventional drawbacks, and embodiments thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a main body having a handle 2 on the upper side and a motor 3 provided inside, the peripheral wall of which projects downward from a bottom plate 4 to form a skirt portion 5. Reference numeral 6 indicates a bumper, and reference numeral 7 indicates a pair of cleaning sections provided below the bottom plate 4 of the main body 1. Since both of the cleaning sections 7 have the same configuration, only one will be explained.

That is, 8 is a drive shaft that is partially supported by a bearing 9 on the bottom plate 4, and a worm gear 1 that meshes with a worm 10 fixed to the shaft of the motor 3 is mounted on the top of the drive shaft.
1 is attached. Reference numeral 12 indicates a rotating brush connected to the lower end of the drive shaft 8, and a brush holder 13
Brush bristles 14 are implanted in a ring shape. A circular detergent foaming chamber 15 that is open upward is recessed in the brush holder 13. The detergent foaming chamber 15 has a tapered inner circumferential wall 17 whose diameter increases in the direction of the bottom surface 16, and the inner circumferential wall 17
A large number of ribs 18 are formed radially along the bottom surface 16. Reference numeral 19 denotes a detergent outflow port protruding from the bottom surface 16, which is located at a certain distance S from the outermost periphery of the bottom surface 16, and whose mouth edge is connected to the detergent foaming chamber 1.
It has been launched within 5.

20 is a boss portion 21 protruding from the bottom plate 4 of the main body 1
The foaming brush 23 is composed of a brush holder 21' fixed to the brush holder 21', and brush bristles 22 whose lower ends are in elastic contact with the outermost periphery of the bottom surface of the detergent foaming chamber 15. is a detergent supply pipe whose tip opening faces the detergent foaming chamber 15, and is connected to a detergent tank 25 via a valve 24. The tank 25 may be built into the main body 1, or may be carried on the operator's back as shown in FIG.

Note that the pair of rotating brushes 12 are configured to rotate in opposite directions to each other so as to cancel out the reactions caused by their respective rotations.

In the above configuration, when the motor 3 is energized now, the rotating brush 12 rotates, and the foaming brush 2
0 rotates relatively within the detergent foaming chamber 15. The bristles 22 of the bristles 22 of the bristles 22 are repelled by the ribs 18 and vibrate as the bristles 20 rotate relative to each other.

However, the liquid detergent supplied to the foaming chamber 15 is foamed by the foaming brush 20 and sent out from the detergent outlet 19.

The rotating brush 12 obtains the detergent and brushes the surface to be cleaned, thereby cleaning the surface.

Moreover, since the inner circumferential wall 17 of the detergent foaming chamber 15 is tapered, the detergent is forcibly moved toward the bottom surface 16 by its centrifugal force. Therefore, even on a vertical surface such as the backrest of the seat shown in FIG. 4, the detergent can be sufficiently fed, thereby ensuring reliable cleaning.

Furthermore, since the detergent outlet 19 is provided displaced by a distance S toward the center of the bottom surface 16, the detergent that has moved along the inner circumferential wall 17 does not foam and does not flow out.

As described above, according to the present invention, it is possible to perform reliable cleaning regardless of the direction of the surface to be cleaned, and the ability of the detergent can be fully utilized. It has excellent effects, such as not causing any damage.
