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 water spray nozzle 2.

[0004]

However, in the above structure, when the amount of the undiluted detergent solution or the dilution water is small, the ejection speed from the sprinkling nozzle 2 becomes slow and the detergent solution cannot reach the wall surface of the bathtub 1, so that the amount of the dilution water is reduced. If it is increased, the detergent liquid 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, and 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 and to efficiently wash the bath. The purpose of.

A second object is to more efficiently and uniformly adhere a small amount of cleaning liquid to a wide surface of the bath with a small amount of cleaning liquid atomizing means.

[0007]

In order to achieve the first object, the present invention provides one or a plurality of cleaning liquid atomizing means arranged in a part of a bath, and a cleaning liquid atomizing means provided in the vicinity thereof. Was
In addition, it is provided with a configuration including an agitating air port main body for discharging air and an air supply means connected to the agitating air port main body for communication.

Further, in order to achieve the second object, the present invention is constituted by arranging air flow left and right flow diverting means in the vicinity of the inside and outside of the outlet of the stirring air port body.

[0009]

According to the present invention, the cleaning liquid is atomized into the bath by the atomizing means, and the cleaning liquid atomized into fine particles having a particle size of about 50 to 100 μm drifts in the space inside the bath. However, if the kinetic energy of the atomized particles is low, the amount of atomized particles that do not reach the bathtub wall far from the atomizing means will settle and the effective deposition efficiency will deteriorate, but it will be supplied from the air supply means via the stirring air port. Kinetic energy is imparted to the atomized particles by the agitated air thus generated, and the atomized particles efficiently adhere to the wall surface of the distant bath to form a liquid film and exert a cleaning action. By atomizing the cleaning liquid in small amounts over a long period of time, the cleaning liquid that has lost the cleaning effect will flow down, but fresh cleaning liquid will newly adhere to the surface to be cleaned, so that an effective cleaning effect will always be obtained. ..

Further, if the number of the cleaning liquid atomizing means and the number of the stirring air ports are reduced, the number of locations on the wall surface of the bath where the atomizing particles of the cleaning liquid are hard to adhere increases, but the air flow left and right provided near the outlet of the stirring air port. The agitating air flow blown out from the agitating air port is swung to the left and right by the non-uniform flow means, so that atomized particles of the cleaning liquid are more uniformly attached to the wall surface of the bath.

Next, the opening / closing plug 27 for rinsing is opened, and the rinsing water pipe 26
Is supplied to the rinsing water injection nozzle 25 via the rinsing water, and water is injected from the rinsing water injection nozzle 25 to rinse away the cleaning liquid residue on the inner wall surface of the bath 6.

Here, the cleaning liquid sprayed in the bathtub 6 with the lid 7 and sprayed on the particles of about 50 μm to 100 m floats in the space in the bathtub 6. However, if the kinetic energy of the atomized particles is low, the number of atomized particles that do not reach the bathtub wall far from the pressure spray nozzle 14 and settle down increases, and the effective deposition efficiency deteriorates. However, kinetic energy is given to the atomized particles by the agitating air supplied from the blower device 12 through the agitating air port body 8, and the atomized particles efficiently adhere to the wall surface of the distant bath to form a liquid film for cleaning. Exert an effect. Therefore, a small amount of cleaning liquid can be uniformly supplied to a wide bath surface by a simple means, and even if considering economical efficiency, a high concentration cleaning liquid can be used if a small amount of cleaning liquid is used. Can be washed.
