Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically cleaning a bath.

[0002]

2. Description of the Related Art A conventional bath cleaning apparatus of this type has a multi-port sprinkling nozzle 2 arranged above a bath 1 as shown in FIG. The detergent supply device 5 is provided in a part of the structure 3.

In the above structure, the bath wall is cleaned while the cleaning liquid supplied from the detergent supply device 5 and the water supply device 4 through the pipe 3 is sprayed from the multi-port sprinkling nozzle 2.
After the washing step, only the water was sprayed from the multi-port sprinkling nozzle 2 to rinse the bath wall.

[0004]

However, in the above-mentioned configuration, the multi-port sprinkling nozzle 2 is arranged near the center of the bath 1 and the number of nozzle ports is not increased so that the cleaning liquid for the bath wall and the rinsing liquid are rinsed. There is a problem that the unevenness of water supply becomes large, and the amount of cleaning liquid and water used also increases even if the number of nozzle openings is increased.

SUMMARY OF THE INVENTION The first object of the present invention is to solve the above-mentioned problems, and it is a first object of the present invention to efficiently perform rinsing after cleaning with a small number of nozzle openings over the entire circumference of the bath even if it is installed near the wall of the bath.

A second object is to efficiently rinse with a small amount of water.

[0007]

In order to achieve the above first object, the present invention provides a cleaning liquid spraying means arranged in a part of a bath and a plurality of flat injection nozzle openings on a horizontal plane and all around. The rinsing water injection nozzle formed so as to have an equal division angle is provided on the upper portion in the vicinity of the wall of the bathtub.

Further, in order to achieve the second object, the present invention is a rinsing in which the height positions of the flat injection nozzle openings formed on the horizontal plane and having the uniform division angle all around the circumference are set to be different from each other. It is composed of a water injection nozzle.

[0009]

According to the present invention, the cleaning liquid is sprayed on the wall surface of the bath by the cleaning liquid spraying means to perform the cleaning process, and then the rinsing water spray nozzle is formed to have a flat spray nozzle opening formed to have an equal circumferential division angle. Water is sprayed as a thin film in the horizontal direction on the entire circumference, and rinsing water is applied to the upper part of the inner wall surface of the bathtub, and while the water flows down the inner wall surface of the bathtub, the cleaning residues on the entire inner wall surface of the bathtub are rinsed away.

If the height positions of the flat jet nozzles are the same, the water jetted from the flat jet nozzles in a thin film upward in the horizontal plane interferes with the water jetted from the adjacent jet nozzles. But the injection angle becomes narrower,
Since the height positions of the spray nozzles are set to be different from each other, the water sprayed by the spray nozzles spreads without interfering with each other, rinsing the cleaning residues on the entire inner wall surface of the bath.

[0011]

Embodiments of the present invention will be described below with reference to FIGS.

In FIGS. 1 and 2, reference numeral 6 denotes a bath having a lid 7. A pressure spray nozzle 8 is arranged in a part of the bath 6, and is connected to a cleaning liquid tank 10 through a cleaning liquid pipe 9 so as to communicate therewith. A pressurizing electromagnetic pump 11 is arranged in a part of the cleaning liquid pipe 9. The cleaning liquid tank 10 is connected to a detergent tank 13 via a detergent pipe 12, and a detergent supply pump 14 is provided in a part of the detergent pipe 12. One end of the diluting water supply pipe 15 is arranged above the cleaning liquid tank 10 so as to be cut off from the cleaning liquid, and the other end is connected to the opening / closing plug 16 and a water supply source (not shown). A fixed quantity water supply plug 17 is provided in a part of the above. On the other hand, a rinsing water injection nozzle 18 is arranged in the upper part near the wall of the other part of the bathtub 6, and is connected to the opening / closing plug 16 and a water supply source (not shown) via a rinsing water pipe 19, An opening / closing plug 20 for rinsing is provided in a part of the rinsing water pipe 19. As shown in FIG. 2, the rinsing water injection nozzle 18 has at least three flat injection nozzle openings 2
1 is formed on a horizontal plane and has an equal division angle all around. Further, the height positions of the three flat injection nozzle openings 21 are set to be different such that the heights are a <b <c.

In the above structure, when the detergent supply pump 14 is operated, a certain amount of detergent is first supplied to the detergent tank 1.
3 is supplied to the cleaning liquid tank 10 through the detergent pipe 12. Next, the opening / closing plug 16 is opened, and the fixed quantity water supply plug 1
As a result of the operation of 7, the amount of water that is far larger than the amount of detergent supplied earlier is supplied to the cleaning liquid tank 10 through the dilution water supply pipe 15 to produce the cleaning liquid. Next, the cleaning liquid is pressurized and supplied to the pressure spray nozzle 8 through the cleaning liquid pipe 9 by the operation of the pressurizing electromagnetic pump 11, and the lid 7
It is sprayed into the bath tub 6 that has been filled. The cleaning liquid atomized into particles of about 50 μm sequentially adheres to the inner wall surface of the bath 6 while drifting in the space inside the bath 6 to form a liquid film, and exerts a cleaning action. When the washing process is completed, the rinsing opening / closing plug 2 is next.
0 is opened and supplied to the rinsing water injection nozzle 18 through the rinsing water pipe 19, and water is injected from the rinsing water injection nozzle 18 to rinse away the cleaning liquid residue on the inner wall surface of the bath 6.

Here, after the cleaning liquid is sprayed onto the wall surface of the bathtub by the pressure spray nozzle 8 and the cleaning process is performed, the rinsing water spray nozzle 18 is entirely sprayed from the flat spray nozzle port 21 formed to have an evenly divided angle around the entire circumference. Water is sprayed in a thin film upward on the horizontal surface of the circumference, and rinsing water is applied to the upper part of the inner wall surface of the bathtub 6, and the water flows down the inner wall surface of the bathtub 6 to rinse away the cleaning residue on the entire wall surface. Since the water jetted from the flat jet nozzle port 21 is in the form of a thin film, even a small amount of water sprays widely and far and can be rinsed efficiently with a small number of nozzle ports.

Further, if the height positions of the flat jet nozzles 21 are the same, the water jetted in a thin film in the horizontal plane upward direction from the flat jet nozzles 21 is adjacent to the jets as shown in FIG. Although it interferes with the water jetted from the nozzle orifices and the jetting angle becomes narrower, the height positions of the three jetting nozzle orifices 21 are set differently, so that the jetting is performed as shown in FIG. The sprayed water spreads without interference, the cleaning residue on the entire inner wall surface of the bathtub 6 can be rinsed off, and the rinse can be efficiently performed with a small amount of water.

[0016]

As described above, in the bath cleaning apparatus of the present invention, the rinsing water injection nozzle having a plurality of flat injection nozzle openings evenly arranged on the horizontal plane and on the entire circumference is provided in the upper part near the wall of the bath. Since it is arranged, even a small amount of water can fly widely and far and can be rinsed efficiently with a small number of nozzle openings.

Further, since the rinsing water injection nozzles are formed so that the flat injection nozzle openings formed on the horizontal plane and at equal circumferential division angles have different height positions, the injection nozzle openings are different from each other. The water sprayed to the surroundings spreads without interfering with each other, and a small amount of water can be used for efficient rinsing.
