Description

[Detailed Description of the Invention] The present invention relates to a bathtub with a scale removal device that can remove scales floating in the bathtub.

Traditionally, the feeling of bathing is alienated by the dirt floating in the bathtub, which often makes people feel uncomfortable. Especially in so-called bubble baths that spray bubbles into the bathtub, there is a lot of dirt floating horizontally. However, there was a drawback that the feeling of bathing was significantly alienated. For this reason, various scale removal devices have been devised, but it is difficult to remove scale floating on the water surface where the water level is constantly changing, and the reality is that there are no actually effective scale removal devices.

The present invention was developed in view of the above-mentioned circumstances, and is a bathtub with a scale removal device that can reliably remove floating matter such as scale floating on the water surface and prevent hot water from accumulating in the pipes. The purpose is to provide The present invention will be described in detail below based on the drawings shown as examples.

FIG. 1 shows the overall diagram.

1 is a bathtub, and a suction 11 is provided at the bottom of the bathtub 1, and water (hot water) in the bathtub 1 is sucked from the suction 11 by operating a pump 8. The water (hot water) discharged from the pump 8 reaches the spout 9 from one of the pipes. At the spout 9, a jet of foam is ejected into the bathtub 1, mixing with the air drawn in through the air intake port 12. The water (hot water) led from the pump 8 to the other piping 10 is sent to another suction pump/foam spout 7 provided on the opposite side from the spout 9.

On the other hand, the water near the top of the bathtub 1 is absorbed by the inner pipe 2, which will be described later.
The water is sucked from the water, passes through the scale removal device 5, reaches the aforementioned spout 7 through the piping 6, and is returned to the bathtub 1 again.

Next, the present invention will be explained in detail based on FIGS. 2 to 4.

In FIG. 2, the inner tube 2 is fixed to the bathtub 1 and stands upright within the bathtub. Further, a drainage hole 13 is provided at the bottom of the inner tube 2. An outer tube 3 is loosely fitted into the inner tube 2 so as to be able to float up and down. 14 is a stopper portion of the outer tube 3. In FIGS. 3 and 4, the pin 1 is inserted into the drain hole 13.
A valve 15 that rotates around 6 is provided. The operating state of the present invention will be explained below with reference to FIGS. 3 and 4. FIG. 3 shows a state in which the pump 8 is stopped, and the outer tube 3 is lowered by its own weight and the valve 15 is opened. (However, the specific gravity of valve 15 is 1
The valve 15 is opened only when the value is larger than 1, and the valve 15 is closed when it is smaller than 1. ) When the water (hot water) in the bathtub 1 is drained in this state, the water (hot water) in the inner tube 2 will also drain out from the drain hole 13 provided in the inner tube 2, and the inner tube 2.It is hygienic as no water (hot water) remains inside. (At this time, the valve 15 is opened by the pressure of the water (hot water) in the inner pipe 2.) Also, when draining water, as shown in FIG. All remaining water (hot water) at the top can be drained out.

Next, when the pump 8 is operated, water (hot water) in the bathtub 1 is sucked in by the suction force of the suction pump/foam spout 7, and the outer tube 3 floats upward due to this reaction force.
Water and air (hot water) are then sucked near the surface of the bathtub. (Valve 15 is closed) This allows oil, floating matter, etc. floating on the surface to be collected efficiently. The water (hot water) sucked into the inner pipe 2 from the outer pipe 3 is guided from the pipe line 4 to the scale removing device 5 to remove dirt, etc., and then reaches the spout 7 through the pipe line 6 and is returned to the bathtub. It will be done. Preferably, the scum removing device 5 is configured such that the filter cloth or the like can be easily replaced from inside the bathtub.

As described above, there is an inner pipe that is fixed upright in the bathtub and has a drainage hole at the bottom, an outer pipe that is loosely fitted into the inner pipe in a floating manner, and a pipe that is installed in the pipe line connected to the inner pipe. The suction device consists of a scale removing device and a suction device that sucks the water (hot water) in the bathtub into an inner pipe and returns the water (hot water) that has passed through the scale removing device back into the bathtub. When the suction device is stopped, the outer tube sinks, and when the suction device is activated, the upper end of the outer tube rises to almost the water surface due to the reaction force of the suction force that draws the water (hot water) in the bathtub into the inner tube, causing the water near the bathtub water surface to rise. The bathtub with a scale removal device according to the present invention has the following characteristics.

Dirt on the water level can be collected according to changes in the water level.

It is sanitary because water (hot water) does not accumulate in the piping.

No special power is required, making it inexpensive and reliable.

Claims (1)

[Scope of utility model registration request] an inner pipe that is fixed upright in the bathtub and has a drainage hole at the bottom; an outer pipe that is loosely fitted into the inner pipe so that it can float up and down;
A scale removal device installed in a pipe line connected to the inner pipe sucks the water (hot water) in the bathtub into the inner pipe, and returns the water (hot water) that has passed through the scale removal device to the bathtub. When the suction device is stopped, the outer tube sinks, and when the suction device is activated, the upper end of the outer tube sinks due to the reaction force of the suction force that draws the water (hot water) in the bathtub into the inner tube. A bathtub with a scum removal device characterized in that the water (hot water) near the bathtub water surface is suctioned from the outer tube into the inner tube by floating to almost the water surface position.
