Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bathtub cleaning device that cleans the inner wall of a bathtub by spraying detergent and water.

(Prior Art) The inner walls of bathtubs tend to get dirty during bathing and need to be cleaned frequently.

After draining the hot water, cleaning is done by sprinkling detergent on the bathtub walls, scrubbing with a sponge scrubber, etc., and spraying water to remove the dirt.After removing the dirt, detergent and hair are removed using a water hose, etc. I try to wash it off.

(Problem to be Solved by the Invention) However, cleaning a bathtub requires considerable effort, and it is difficult to completely remove residual detergent and hair from the inner walls of the bathtub. For example, when washing by spraying water with a water hose or the like, detergent and hair may remain in areas that are not exposed to water.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a bathtub cleaning device that automatically and evenly rinses the bathtub with a water jet nozzle provided on the inner wall of the bathtub.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides the following features:
The nozzle tip of a fine spray nozzle for spouting detergent and water is provided in a protruding manner, and the tip of the water spray nozzle is exposed on the protruding inner wall of the fine spray nozzle and on the inner wall opposite to the inner wall. The water injection nozzle has a linear cut that expands toward the tip, and an injection port is bored in the middle of the cut, so that the longitudinal direction of the cut coincides with the substantially horizontal direction. The spray nozzle is provided on the inner wall of the bathtub with the spray port oriented diagonally upward, and means for selectively supplying water or detergent and means for supplying compressed air are connected to the fine spray nozzle. The fine spray nozzle sprays detergent into the bathtub, and the water spray nozzle sprays water into the bathtub to wash away dirt on the inner walls of the bathtub together with the detergent.

(Function) After draining the hot water in the bathtub and closing the bathtub with the bathtub lid,
The detergent is discharged into the bathtub as a fine mist from the fine spray nozzle. In this case, by supplying compressed air to the fine atomizing nozzle, the detergent is sucked into the fine atomizing nozzle and becomes a fine atomizing,
The finely atomized detergent diffuses and fills the bathtub evenly and adheres to the entire inner wall of the bathtub as fine droplets. This allows the detergent to evenly penetrate the entire surface of the inner wall of the bathtub, making it easier to clean dirt stuck to the inner wall.

Water is then jetted from one of the water jet nozzles. In this case, since the longitudinal direction of the notch is aligned with the substantially horizontal direction and the jetting port is provided on the inner wall with the jetting port oriented diagonally upward, the water jetted from the jetting port is diffused in a substantially horizontal direction along the notch. The water is distributed all over the inner wall of the bathtub, and the water droplets flow down the inner wall of the bathtub along with the detergent to the bottom of the bathtub. Furthermore, water is jetted from the other water jet nozzle.

As a result, the inner walls of the bathtub and the entire surface of the bathtub lid are washed away, so that dirt, detergent residue, hair, etc. on the inner walls of the bathtub are washed away.

(Example) Next, a bathtub cleaning device according to the present invention will be described below using Example J, with reference to the attached drawings.

Next, a detergent tank 21 is connected to the detergent selection valve 12 as a detergent solution supply source. In addition, water selection valve 1.1
, tap water is supplied to the water source valve 16.

The bathtub 1 is provided with a bathtub lid 22, and the bathtub lid 2
A lid switch 23 is provided to detect the open/closed state of the lid switch 2.

Furthermore, a drain valve 24 is provided at the bottom of the bathtub 1. The components of the bathtub cleaning device 2 are configured to perform a control operation to selectively supply water and detergent based on control commands from the control unit 25.

Therefore, the operation of the bathtub cleaning device 2 will be explained below.

Open the drain valve 24 to drain the hot water in the bathtub 1, and then close the bathtub lid 2.
After the bathtub is closed by step 2 and the closed state is detected by the lid switch 23, the control section 25 outputs a valve opening control command for the detergent selection valve 12 and starts the near compressor 4. As a result, the detergent is absorbed from the detergent tank 21 through the detergent selection valve I2, the detergent supply pipe 9, and the washing side supply pipe 0 to the fine spray nozzle 4, and is finely sprayed into the bathtub 1 for a certain period of time. (For example, 20 seconds, 20cc) is ejected. In this case, since the ejection lower formed at the tip 6 of the fine spray nozzle 4 is formed to be approximately horizontal and to be flush with the bottom of the gap and the inner M3 surface, the spray Fine detergent droplets scatter not only forward but also laterally, filling the bathtub 1.

Then, the detergent penetrates into the dirt stuck to the inner wall 3 of the bathtub 1, making it easy to clean.
can be removed from the drain valve 24 by activating the air supply tube I3 and injecting air from the fine spray nozzle 4.

Next, the control unit 25 closes the water selection valve j1, and
The water source valve 16 is opened, the switching valve 17 is operated to supply water to one of the water injection nozzles 5, and the drain valve 24 is opened to supply water to one of the water injection nozzles via the water supply pipe 15. Supplied to nozzle 5. The water injection nozzle 5 is disposed on the inner wall 3 opposite to the inner wall 3 on which the fine spray nozzle 4 is protruded, and is installed in the bathtub 1.
