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 dirt.After removing the dirt, detergent and hair are removed using a water hose, etc. Wash it off.

(Problem to be Solved by the Invention) However, cleaning a bathtub requires considerable effort, and it is difficult to remove detergent and hair left on the inner wall 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 sprays water from the bottom of the bathtub to automatically and evenly wash the bathtub.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides the following features:
A nozzle tip of a fine spray nozzle for spraying detergent and water is provided in a protruding manner, and a water spray nozzle having a function of dispersing and spraying water toward the top of the bathtub is provided approximately in the center of the bottom of the bathtub.
Means for selectively supplying water or detergent and means for supplying compressed air are connected to the fine spray nozzle, and the fine spray nozzle sprays detergent into the bathtub and also sprays water. A 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 inner wall of the bathtub.
This makes it easier to clean dirt stuck to the inner walls.

Then, water is jetted from the water jet nozzle to wash away the inner wall of the bathtub and the entire surface of the bathtub lid, so that the remaining detergent and hair are washed away along with the dirt.

In this case, the water spray nozzle is located approximately at the center of the bottom of the bathtub, and the water is diffused and sprayed, so that the water efficiently spreads over the entire inner wall of the bathtub.

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

FIG. 1 shows a bathtub 1 provided with a bathtub cleaning device 2. As shown in FIG.

This bathtub cleaning device 2 has a fine spray nozzle 4 for spouting detergent and water, and a water spray nozzle 5 having a function of spraying the fine spray upward in a substantially conical shape toward the top of the bathtub. The nozzle 4 is disposed on the upper surface of the inner wall 3 on the short side of the bathtub 1 so that its nozzle surface is exposed inside the bathtub 1, while the water jet nozzle 5 is disposed approximately at the center of the bottom of the bathtub 1.

The tip 6 of the fine 9N nozzle 4 is provided with an ejection lower which is a gap formed so as to divide the tip 6 into two. The forming direction is made to substantially coincide with the horizontal direction, and the bottom of the gap is flush with the inner wall 3 of the bathtub 1, and only the tip 6 is formed to protrude from the upper surface of the inner wall 3. (See Figures 2a and 2s).

A washing side supply pipe 10 is connected to the fine spray nozzle 4, which is a water supply pipe 8 for supplying water and a detergent supply pipe 9 for supplying a detergent solution. 8 includes a water selection valve 11 for selectively supplying water.
The detergent supply pipe 9 is provided with a detergent selection valve 12 for selectively supplying a detergent solution.

Further, a near compressor 14 is connected to the fine spray nozzle 4 via an air supply pipe 13 for supplying compressed air.

On the other hand, a water supply pipe 15 for supplying water is connected to the water injection nozzle 5, and a water source valve 1 for cutting off the supply of water is connected to the water injection nozzle 5.
6 is interposed. Here, the water injection nozzle 5 will be explained in detail below. As shown in FIGS. 3a and 3b, the water injection nozzle 5 has a cylinder W17 whose outer periphery is threaded and whose both ends are open ends. The opening areas of the two ends are different, and the water supply pipe 15 is connected to the end with a small opening area, while the end with a large opening area is connected to the water supply pipe 15.
A nozzle forming member 18 is fitted. This nozzle forming member 18 protrudes from the vicinity of the end in the cylindrical tube 17 toward the outside of the end, and has a dividing wall I9 that divides the inner space of the cylindrical tube 17 into two, and a body on both sides of the dividing wall I9. The inclined portions 20a, 2 are formed in a manner that is opposite to each other.
0b. These inclined parts 20a and 20b have a first nozzle 21a and a second nozzle 21a.
A nozzle 21b is provided. the inclined portion 20a;
20b forms the spray angle α of the water spray nozzle 5.

Next, a detergent tank 22 is connected to the detergent selection valve 12 as a detergent solution supply source. In addition, water selection valve +1,
Tap water is supplied to the water source valve 16.

The bathtub 1 is provided with a bathtub M23, and this bathtub lid 2
A lid switch 24 is provided to detect the open/closed state of 3.

Furthermore, a drain valve 25 is provided at the bottom of the bathtub 1. The components of the bathtub cleaning device 2 are configured to perform control operations for selectively supplying water and detergent based on control commands from the control unit 26.

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

Open the drain valve 25 to drain the hot water in the bathtub 1, and then close the bathtub lid 2.
After the bathtub is closed by step 3 and the closed state is detected by the lid switch 24, the control section 26 outputs a valve opening control command for the detergent selection valve 12 and starts the near compressor 14. As a result, the detergent is sucked from the detergent tank 22 through the detergent selection valve 12, the detergent supply pipe 9, and the flush side supply pipe 10 to the fine spray nozzle 4, and is finely sprayed into the bathtub 1 for a certain period of time (e.g. , 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 wall 3, the spray The fine detergent droplets diffuse not only forward but also laterally, filling the bathtub l.

The detergent penetrates into the dirt stuck on the inner wall 3 of the bathtub 1, making it easy to clean. The fine spray of detergent still remaining in the bathtub l can be removed from the drain valve 25 by activating the near compressor 14 and blowing out air from the fine spray nozzle 4 through the air supply pipe 13. I can do it.

Then, the control unit 26 closes the water selection valve 11 and opens the water source valve 16, and further supplies water to the water injection nozzle 5 via the water supply pipe 15. The water injection nozzle 5 is located approximately at the center of the bottom of the bathtub 1, and the water is directed to the first nozzle 21 by a nozzle forming member I8 fitted in the cylindrical pipe 17.
a, through the second nozzle 21b, it passes along the inclined parts 20a and 20b, which are formed to be inclined so as to be opposite to each other, so that it is diffused and injected in the direction of the angle α formed between the inclined parts 20a and 2Ob. As a result, water efficiently spreads over the entire surface of the inner wall 3 of the bathtub l and the bathtub lid 23. Dirt, detergent residue, hair, etc. on the inner wall 3 of the bathtub l are then washed away.

(Effects of the Invention) As described above, according to the present invention, the following effects are achieved. That is, the detergent is ejected in the form of fine droplets into the bathtub in advance, diffuses and fills the bathtub, and adheres to the inner wall of the bathtub, thereby forming a thin film of detergent on the inner wall of the bathtub. Therefore, the detergent penetrates into the dirt stuck to the inner walls of the bathtub, making it easier to clean. In this state, water is jetted from the water jet nozzle provided approximately at the center of the bottom of the bathtub, so that dirt, detergent residue, hair, etc. on the inner wall of the bathtub are washed away. In this case, since the water jet nozzle has a function of diffusing and jetting water, the water is distributed all over the inner wall of the bathtub, allowing efficient cleaning.

In this way, the entire inner wall of the bathtub is evenly covered with detergent, which is then washed away with a jet of water, making it possible to clean the bathtub evenly without scrubbing, only using a small amount of detergent, and the equipment is simple. , economical. Additionally, since it can be cleaned automatically, the bathtub cleaning device is especially suitable for busy households.
