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 In a conventional bathtub cleaning apparatus of this type, as shown in FIG. 3, a water spray nozzle 2 is disposed above a bathtub 1, and a pipe 3 communicates with a water supply device 4.
The detergent supply device 5 is provided in a part of the above.

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.

[0004]

However, in the above-mentioned structure, when the amount of the undiluted detergent solution or the dilution water is small, the jetting speed of the washing solution from the sprinkling nozzle 2 becomes slow and the detergent solution cannot reach the wall surface of the bathtub 1. However, when the amount of dilution water is increased, the detergent solution reaches the wall surface of the bathtub 1, but the detergent concentration is lowered, so that there is a problem that the cleaning ability is lowered. Further, even if the cleaning liquid is sprayed on the vertical wall of the bathtub 1, it immediately flows down, and there is a problem that the cleaning effect of the detergent cannot be effectively utilized.

The present invention is intended to solve the above-mentioned problems. It is necessary to uniformly supply a cleaning liquid to a wide surface of a bath so that a high-concentration cleaning liquid can be used in a small amount to efficiently wash the bath. The second object of the present invention is to more efficiently and uniformly attach a small amount of cleaning liquid to a wide surface of the bath with a small amount of cleaning liquid atomizing means.

[0006]

In order to achieve the above first object, the present invention provides a stirring means for arranging a cleaning liquid atomizing means arranged in a part of a bath in a substantially central portion and discharging air. An air inlet body, a plurality of air supply passages connected to the stirring air inlet body, an air supply means disposed at the other end of these air supply passages, left and right air supply passages, and an air supply means. An air flow switching means interposed therebetween, a partition wall partitioning the inside of the stirring air port body into a plurality of parts so as to communicate with each of the air flow passages, and a partition wall on the opening side of the stirring air port body. And an air guide arranged at the end.

In order to achieve the second object, according to the present invention, air is supplied to each air supply passage by the air flow switching means only on one side and only on the other side, and simultaneously on one side and the other side.
The air flow switching control means for sequentially operating in the type mode is provided.

[0008]

According to the present invention, the cleaning liquid is atomized by the atomizing means into fine particles having a particle size of about 50 to 100 μm and drifts in the space in the bath. However, since the kinetic energy of atomized particles is low, the number of atomized particles that settle without reaching the bath wall far from the atomizing means increases, and the effective adhesion efficiency deteriorates.
Kinetic energy is given to the atomized particles by the agitating air supplied from the air supplying means through the agitating air port, and the air flow that is sent by being switched to each air supply passage by the air flow switching means is the agitating air port body. Since it blows out through a plurality of passages divided by a partition wall and changes its direction to one or the other by an air guide, atomized particles also efficiently adhere to the wall surface of the bath in a wide range of the other side and the liquid film. Form a cleaning effect.

Further, the atomized particle group carried by the air flow switched to each air supply passage by the air flow switching means is largely biased to one side when switched to one side,
When it is switched to the other side, it tends to be biased toward the other side. On the other hand, when only the other side is switched, the amount of atomized particles attached to the bathtub wall in front of the atomizing means is reduced. By setting the mode to supply the air flow to the air supply passages on both sides of the one side, the amount of atomized particles adhering to the bathtub wall in front of the atomizing means is increased by the interaction of the other air flow, so that it is more uniform. The atomized particles of the cleaning liquid adhere to the wall surface of the bath.

The cleaning liquid tank 16 is connected to a detergent tank 20 via a detergent pipe 19, and the detergent pipe 19 is connected to the detergent tank 20.
A detergent supply pump 21 is provided in a part of the above. One end of a diluting water supply pipe 22 is arranged above the cleaning liquid tank 16 so as to be cut off from the cleaning liquid, and the other end is connected to an opening / closing plug 23 and a water supply source (not shown). A fixed quantity water supply plug 24 is provided in a part of the above. The fixed amount water supply plug 24 may be an open / close valve that operates in conjunction with the liquid level detecting means provided in the cleaning liquid tank 16.

On the other hand, a rinsing water injection nozzle 25 is arranged in the other portion of the bathtub 6, and is connected to the opening / closing plug 23 and a water supply source (not shown) via a rinsing water pipe 26.
An opening / closing plug 27 for rinsing is provided in a part of the rinsing water pipe 26. The outer surface of the nozzle holder 15 is vertically divided along the longitudinal direction of the nozzle holder 15 so that the inside of the stirring air port body 8 is independently communicated with the upper air supply passage 11 and the lower air supply passage 11. A partition wall 28 is installed, and an air guide 29 opened in a wedge shape at an angle of about 60 ° is provided at an end of the partition wall 28 on the opening 8a side of the stirring air port body 8.

A cover base 3 is provided on the outer periphery of the air outlet member 9.
0 is provided, and the nozzle cover 31 is provided in front of it. In the air flow switching means 12, the air flow switching control means 3 for sequentially operating the air supply to the upper and lower air supply passages 11 only in the upper side, only in the lower side, and in the upper and lower simultaneous modes.
Two are provided.

In the above structure, when the detergent supply pump 21 is operated, a certain amount of detergent is first supplied to the detergent tank 20.
Further, it is supplied to the cleaning liquid tank 17 through the detergent pipe 19. Next, the opening / closing plug 23 is opened and the fixed quantity water supply plug 24 is opened.
By the operation of, a certain amount of water is supplied to the cleaning liquid tank 17 through the dilution supply pipe 22 to prepare the cleaning liquid. Next, this cleaning liquid is pressurized and supplied to the respective pressure spray nozzles 14 via the cleaning liquid pipe 16 and the nozzle holder 15 by the operation of the pressurizing electromagnetic pump 18, and is sprayed into the bath 6 with the lid 7. The air blower 13 is operated almost at the same time as the spraying, and the air sent from the air supply passage 11 into the stirring air port body 8 via the air flow switching means 12 is
Air outlet member 9 and cover base 28 from the stirring air port 8a
And it passes through the nozzle cover 29 and is blown out into the bathtub 6. The cleaning liquid atomized into particles of about 50 to 100 μm adheres to the inner wall surface of the bath 6 to form a liquid film. When the cleaning process is completed, the rinsing opening / closing plug 27 is then opened and supplied to the rinsing water injection nozzle 25 via the rinsing water pipe 26, and water is injected from the rinsing water injection nozzle 25 to clean the inner wall surface of the bathtub 6. Rinse the wash residue.

Here, the cleaning liquid sprayed on the fine particles of about 50 μm to 100 m sprayed in the bath 6 with the lid 7 floats in the space inside the bath 6. Since the kinetic energy of the atomized particles is not high, the amount of atomized particles that settle down without reaching the front wall of the bathtub 6 far from the pressure spray nozzle 14 increases, and the effective deposition efficiency deteriorates. However, the kinetic energy is given to the atomized particles by the stirring air supplied from the blower device 13 through the stirring air port 8a of the stirring air port body 8, and the air flow switching means 12 switches the upper and lower air supply passages 11. The air flow thus sent is blown out by changing its direction upwards or downwards by an air guide 29 through a passage that is vertically divided by a partition wall 28 in the agitation air port main body 8, so that the atomized particles are also wide on the left and right. Efficiently adheres to the wall surface of the bathtub 6 in the range to form a liquid film and exert a cleaning action.
Therefore, a small amount of cleaning liquid can be uniformly supplied to a wide surface by a simple method, and even if considering economical efficiency, a high-concentration cleaning liquid can be used if a small amount of cleaning liquid is used. You can

The atomized particle group carried by the air flow switched to the upper and lower air supply passages 11 by the air flow switching means 12 is largely biased to the upper side when switched to the upper side, and is switched to the lower side when switched to the lower side. The amount of atomized flow adhered to the bathtub wall in front of the pressure spray nozzle 14 decreases by switching only to the upper and lower sides, because it is biased toward the lower side, but the air flow switching control means 32 causes the air flow to the air supply passages on both the upper and lower sides. By setting the supply mode, the amount of atomized particles adhered to the bath wall in front of the pressure spray nozzle 14 is increased by the interaction of the upper and lower air flows, so that the atomized particles of the cleaning liquid adhere more uniformly to the wall surface of the bath. To be done.

Further, when the cleaning process and the rinsing process are completed, the air blower 13 can be operated to dry the bath 6 and a bath cleaning device for completely porcelain clay can be obtained.
