Abstract

PURPOSE:To mechanize the cleaning operating of a stool, to reduce the burden of persons in charge of cleaning and to improve an operating speed by providing a detergent tank in a frame and hollowing a part of a rotation axis and a flexible member so as to enable detergent or water to pass. CONSTITUTION:A stool cleaner 1 is placed on the rim B1 of a stool B and a motor 6 is started. The motor 6 drives a rotation axis 3 in the order of low speed, intermediate speed, high speed and low speed... through a control portion 11. A brush 5 is located at positions shown by imaginary lines if centrifigal force is large, and at a position shown by solid lines when it stops to thereby clean the inner face of the stool through detergent and water mixture. A starting switch or a timer are incorporated in the control portion 11 so as to urge an automated operation. Since a frame 2 and the rim B1 are tightly connected by a rubber packing 12, there is not possibility of splashing cleaning water to the outside of the stool B.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a toilet bowl cleaning machine.

(Prior Art) Conventionally, toilet bowls have been cleaned manually using a brush with a grip. Since the work is done manually and inside a narrow toilet seat, the time required for cleaning is not short and the work efficiency is not good.

(Section 8: Invention or Solution) As a result, the usable time of the toilet room is shortened, which is inconvenient for the users. In addition, the inner surface of the toilet bowl is dirtier than the outer surface, making this work undesirable.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to mechanize the cleaning work of toilet bowls to reduce the burden on cleaning workers, and to improve the work speed and shorten the cleaning period.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a frame placed on the rim of a toilet bowl, a rotating shaft supported by the frame, and a flexible member connected to the lower end of the rotating shaft. The toilet bowl cleaning machine consists of a brush attached to the toilet bowl.

Furthermore, a detergent tank is provided within the frame, and a portion of the rotating shaft and the flexible member are formed into a hollow structure to allow detergent and water to pass through.

(Operation) By placing the brush in the toilet bowl and rotating the rotating shaft,
The centrifugal force causes the brush to move diagonally or horizontally, scrubbing the inner surface of the toilet bowl.

By changing the rotation speed, the height position of the brush is changed to completely clean the inside surface of the toilet bowl.

At this time, an appropriate amount of detergent stored in the frame is discharged through the flexible member, thereby increasing the cleaning ability.

(Example) Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a cross-sectional view of a toilet bowl cleaning machine according to the present invention.
The rotating shaft 3 is vertically supported by the frame 2 via a bearing, a flexible member 4 in the shape of a flexible tube attached to the lower end of the rotating shaft 3, and a brush 5 at the tip thereof.

The frame 2 is made of a light metal such as aluminum or resin, has a hollow structure, and is extremely lightweight.

The rotating shaft 3 is connected to a variable speed motor 6 at its upper end, and
A water tank 7 and a detergent tank 8 are arranged on the frame 2.

The metering pump 7a of the water tank 7 and the metering pump 8a of the detergent tank 8 are respectively driven by the motor 6 via a pulley and a belt. In the figure, 9 is a handle.

FIG. 2 is an enlarged cross-sectional view of the main part of FIG.
・Tune 7b from left and right,
The water and detergent supplied through 8b pass through the mixing chamber 1O, the hollow passage 3b, and the inside of the flexible member 4, and are discharged in appropriate amounts from the small holes 5a of the brush 5.

The operation of the toilet bowl cleaning machine constructed as described above will be described below.

A cleaning worker places the toilet bowl cleaning machine 1 on the rim Bl of the toilet bowl B and starts the motor 6.

There is a control unit 11 on the side of the motor 6 that changes the speed cyclically, and the motor 6 supplied with power via this drives the rotating shaft 3 in the order of low speed → medium speed → high speed → low speed... do. As a result, the water pump 7a and the detergent pump 8a also start supplying water and detergent.

If the centrifugal force is large, the brush 5 will be at the position shown by the imaginary line in FIG. 1, will stop at the position shown by the solid line, and will move between the intermediate rotational speed levers.

The brush 5 cleans the inner surface of the toilet bowl via the detergent-water mixture.

By incorporating a start switch and a timer into the control unit 11, automation of work is facilitated.

During this time, the frame 2 and the rim Bl are connected to the rubber gasket 12.
There is no risk of flushing water splashing outside of the toilet bowl B since the toilet bowl B is in close contact with the toilet bowl B.

FIG. 3 is a diagram showing another embodiment of FIG. 1, and this toilet cleaning machine 2
No. 1 is characterized in that the hollow frame 22 is divided into a water tank 27 and a detergent tank 2B. Other constituent elements are the same as those in FIG. 1, so their explanation will be omitted.

Further, as shown in the figure, the motor 26 is flat and has a small dimension in the axial direction, and is covered with a cover C to improve dustproofness and to achieve overall compactness.

It is preferable that the rotating shaft 3 be driven by a motor, or it may be driven manually via a manual handle or a gear speed increaser.

Furthermore, the water tank 7.27 in the embodiment may be abolished and the flushing water may be replaced with water supplied from a low tank, etc. (Effects of the Invention) As described above, according to the present invention, toilet cleaning work can be mechanized. This can significantly lighten the burden on the cleaning worker, shorten the working time, and extend the usable time of the toilet room.
