Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus and method for automatically cleaning bathtubs.

2. Description of the Related Art A conventional bathtub cleaning device of this type was constructed as shown in FIG.

That is, a water spray nozzle 2 was disposed above the bathtub 1 and was connected to a water supply device 4 through a pipe 3, and a detergent supply device 5 was provided in a part of the pipe 3.

Problems to be Solved by the Invention However, with the above configuration, if the amount of detergent stock solution or dilution water is small, the spray speed from the water spray nozzle 2 will be slow and the detergent solution will not reach the wall surface of the bathtub 1, and if the amount of diluted water is increased, The problem is that the detergent solution reaches the walls of bathtub 1 (but the detergent concentration decreases, resulting in a decrease in cleaning performance. Furthermore, even if the detergent solution is sprayed onto the vertical wall of bathtub 1, it immediately runs off, reducing the detergent concentration. The problem was that the cleaning effect could not be used effectively.

The present invention aims to solve such conventional problems, and aims to efficiently clean a bathtub by continuously supplying a small amount of high-concentration cleaning liquid to a wide area.

Means for Solving the Problems In order to solve the above problems, the automatic bathtub cleaning device of the present invention has a large number of discharge ports provided around the upper part of the bathtub, and a header pipe connected to these discharge ports is connected to the bathtub. This header pipe is connected to the drain pipe provided at the bottom of the bathtub by a circulation pipe, and a circulation pump is installed in a part of this circulation pipe, and the circulation pump and the header pipe are connected to each other by a circulation pipe. A detergent supply means is provided in between, a water supply means is provided to supply water to the circulation pipe, an automatic drain plug is provided at the other end of the drain pipe, and an appropriate gap is provided between the outlet and the outlet so as to cover the front surface of the outlet. It is equipped with a guide.

According to the above-described structure, when the automatic cleaning operation is started after bathing, the automatic drain valve is first opened and the hot water in the bathtub is drained. After detecting the completion of drainage, the automatic drain valve is closed.
The detergent supply means and the water supply means are operated to supply a constant amount of water and detergent in an appropriate ratio. The supplied cleaning liquid passes through the circulation pipe, reaches the header pipe, flows into the bathtub through a number of discharge ports connected to the header pipe, and flows down while evenly contacting the vertical walls of the bathtub. The cleaning liquid accumulated at the bottom of the bathtub is operated by the circulation pump to reach the circulation pipe/header pipe again through the drain pipe, flows into the bathtub from multiple discharge ports, and washes the bathtub wall surface while flowing down the vertical wall of the bathtub. When the cleaning process is completed, the operation of the circulation pump is stopped, the automatic drain valve is opened, and the dirty cleaning liquid in the bathtub is drained. Next, a large amount of water is supplied by the water supply means and ejected from the discharge port, but the water hits the scattering guide, changes its direction downwards, and flows down the vertical wall of the bathtub with great force, rinsing away the residue of the cleaning solution and draining the water into the drain pipe. and drained via an automatic drain valve.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. 1 of the accompanying drawings.

In FIG. 1, a number of discharge lowers are bored around the upper part of the bathtub 6, and a header pipe 8 is connected to these discharge lowers.
is arranged around the bathtub, this header pipe 8 and a drain pipe 9 provided at the bottom of the bathtub 6 are connected through a circulation pipe 10, and a circulation pump 11 is arranged in a part of this circulation pipe 10. A detergent supply pump 12 and a detergent tank 13 are provided between the circulation pump 11 and the header pipe 8, a water supply on-off valve 14 for supplying water to the circulation pipe 10 is provided, and an automatic drain plug 15 is provided at the other end of the drain pipe 9. The scattering guide 16 is disposed with an appropriate gap from the discharge lower so as to cover the front surface of the discharge lower.

In the above configuration, when the automatic cleaning operation is started after bathing is completed, the automatic drain valve 15 is first opened and the hot water in the bathtub 6 is drained. After detecting the completion of drainage, the automatic drain valve 15 is closed, and a certain amount of detergent is supplied from the detergent tank 13 by the detergent supply pump 12, and a certain amount of water is supplied in an appropriate ratio by the operation of the water supply on/off valve 14. be done. The supplied cleaning liquid passes through the circulation pipe 10, reaches the header pipe 8, flows into the bathtub 6 through a number of discharge lowers connected to the header pipe 10, and flows down while evenly contacting the vertical walls of the bathtub 6. do. The cleaning liquid accumulated at the bottom of the bathtub 6 is circulated again in the order of the circulation vibrator 10, the header pipe 8, the discharge lower, and the bathtub 6 via the drain pipe 9 by operation of the circulation pump 11. When the cleaning process is completed, the operation of the circulation pump 11 is stopped, the automatic drain valve 15 is opened, and the dirty cleaning liquid in the bathtub 6 is drained. Next, when the water supply on/off valve 14 is opened, a large amount of water is supplied and ejected from the discharge lower, but the water hits the scattering guide 16, changes its direction downward, and flows down the vertical wall of the bathtub 6 with great force, releasing the cleaning liquid. The residue is rinsed away and discharged via drain pipe 9 and automatic drain plug 15.

Here, the cleaning liquid diluted to an appropriate high concentration spreads slowly and flows down the vertical wall surface of the bathtub 6 from a number of discharge lowers drilled around the upper part of the bathtub 6, and the circulation is repeated, so that cleaning can be carried out efficiently. can be performed continuously. Next, at the time of rinsing, a large amount of water ejected from the discharge lower is scattered by the scattering guide 16 and flows down the wall of the bathtub 6 with great force, resulting in efficient rinsing. There will be no need for it.

Effects of the Invention As described above, the automatic bathtub cleaning device of the present invention provides the following effects.

(1) A large number of discharge ports are drilled around the upper part of the bathtub, and a circulation pipe is used to connect the hender pipe connected to these discharge ports and an automatic drain plug provided at the bottom of the bathtub, and the circulation Since a circulation pump is disposed in a part of the pipe and a detergent supply means is provided, a small amount of highly concentrated cleaning liquid can be continuously supplied to a wide area to efficiently clean the bathtub.

(2) A scattering guide is placed with an appropriate gap between the outlet and the outlet so as to cover the front surface of the numerous outlets drilled around the top of the bathtub, so that when the cleaning solution is circulated, a small amount of the cleaning solution will slowly spread to the wall of the bathtub. When rinsing, a large amount of water ejects from the discharge port is scattered by a scattering guide and flows down the bathtub wall with great force for efficient rinsing. There is no need to separate the bathtub and the bathtub, and the structure is simple and there is no protrusion into the bathtub, making it extremely safe.
