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-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, and an object thereof is 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. To do.

[0006]

In order to achieve the above-mentioned object, the present invention has a stirring air port for arranging a cleaning liquid atomizing means arranged in a part of a bath in a substantially central portion and discharging air. A main body, an air supply passage connected to the main body for stirring air, and an air supply means arranged at the other end of the air supply passage are provided, and the spray port of the cleaning liquid atomizing means is at least in the center and both sides thereof. In addition, it is provided with a configuration in which a plurality of them are provided while being inclined outward.

[0007]

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, if the kinetic energy of the atomized particles is low, the effective deposition efficiency deteriorates because the amount of atomized particles that do not reach the bathtub wall far from the atomizing means settle and the effective adhesion efficiency deteriorates. Kinetic energy is given to the atomized particles by the supplied stirring air and reaches the bath wall far from the atomizing means. On the other hand, it is difficult to reach the bathtub wall on the side where the atomizing means is installed, no matter how much air is entrained by the agitated air, simply by spraying it on the front side. The atomized particles discharged from the atomizing port can easily get caught in the vortex of the stirring air flow ejected from the main body of the stirring air port, so that it can effectively reach the bath wall on the side where the atomizing means is installed and the cleaning liquid is atomized. The particles efficiently adhere to the entire circumference of the wall surface of the bath to form a liquid film, which exerts a cleaning action.
