Abstract

PURPOSE:To improve a fur collecting capacity by a method wherein a fur collecting device for sucking fur on the surface of bath tub water is provided and an injection flow port is arranged in the bath tub to face downwardly in such a way as water surface flow is generated. CONSTITUTION:A circulation pump 5 is operated to circulate bath tub water 7 in upper and lower circulation pipes 3 and 4 as indicated by arrow. With this operation, the water injected from an injection nozzle 20 generates a negative pressure by an injecting force to suck water within a circulation passage 15 and then the water is injected downwardly from the injection port 22 into the bath tub 9. With this operation, the water becomes a surface flow by circulating water as indicated by arrow from a suction port 19a. At this time, fur 4 is also sucked, filtered by a filter 16 and hot water is filtered and returned into the bath tub 9. With this arrangement, a collecting capacity is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the structure of a bathtub water purification device for removing scale, hair, etc. floating on the surface of bathtub water.

Conventional technology In general, floating objects such as scale, dirt, hair, etc. floating in the bath water create a feeling of unsanitary health for those who are trying to take a bath.
I was very dissatisfied with this. It was a hassle to scoop up and remove floating objects still floating in the bathtub water with a container or the like.

Therefore, a bathtub water purification device as shown in FIG. 2 can be considered.

Reference numeral 1 denotes a bath heat exchanger, which is installed inside a bath pot case 8 and has a circulation pump 5 for circulating bath water on the outlet side. bathtub 9
is connected to the bath heat exchanger 1 through a lower circulation pipe 2 and an upper circulation pipe 3. 4 is the scale floating on the upper surface of the bath water 7, 15 is passing through the lower circulation pipe 2 and directing the inlet 15a toward the bathtub 9 side;
A circulation path consisting of a pipe connecting an outlet 15b to the bathtub 9 via the upper circulation pipe 3; 16 a filter for removing floating matter 4; It is attached removably. 18
19 is an upright fixed pipe connected to the holder 17 and communicated with the inlet 15a via the filter 16, and 19 is connected to the fixed pipe 18 so as to be movable up and down, and the upper water intake port 19a can be moved below the water surface by buoyancy. The pipe body and the pump 5 have their suction ports connected to the outlet side of the bath heat exchanger 1, and their discharge ports connected to the upper circulation pipe 3. The upper circulation pipe 3 has an acupuncture point pipe 3a on the side connected to the bathtub 9, and a jet nozzle 20 communicating with the narrow upper circulation pipe 3 is installed in the acupuncture point pipe 3a, and a circulation path 15 facing the large diameter pipe 3a is installed in the upper circulation pipe 3.
It is located earlier than the A gap is provided at the tip of this jet nozzle 20 so that the jet port 21 faces the outlet of the acupuncture point pipe 3a of the upper circulation pipe 3 approximately horizontally.

In the above configuration, when the circulation pump 5 is operated to circulate the bathtub water, the bathtub water that has passed through the upper circulation pipe 3 is vigorously squirted from the spout nozzle 20 into the jet port 21 inside the large diameter pipe 3, and at this time, the water is spouted out. Water in the circulation path 15 is sucked out by the negative pressure generated around the nozzle/l/20 and enters the large-diameter pipe 3a, and water is also jetted into the bathtub 9 from the jet port 22. Therefore, when the water in the circulation path 15 is completely suctioned, the fixed pipe 1
8. In order to cover the pressure difference between the upper and lower sides of the pipe body 19, the water intake port 19a of the pipe body 19 rises to the water surface, and the floating matter 4 is sucked in from the water intake port 19a along with the clean water, and the fixed pipe 18,
After passing through the filter 16 and removing the suspended matter 4 with the filter 16, the bath water 7 from which the suspended matter has been removed is sent to the circulation path 15.
, large-diameter pipe 3 & enters the bathtub 9 through the jet port 22 .

The above circulation is repeated, and the suspended matter 4 is transferred to filter 1.
It is removed at 6.

The bath water 7 is sucked into the suction port of the circulation pump 5 through the gap formed between the lower circulation pipe 2, the holder 17, and the circulation path 150, and through the lower circulation pipe 2 and the bath heat exchanger 1. . In addition, the tube body 19, the fixed tube 18, the holder 1
7. The filter 16, the circulation path 15, the jet nozzle 20, the jet port 21, etc. constitute a scum collection device.

Problems to be Solved by the Invention Since the jet orifice 21 shown in FIG. 2 is oriented horizontally, the flow of the bathtub water 7 discharged from the jet orifice 21 is a combination of the horizontal discharge force and the force trying to float. As the resultant force acts and the ejection force weakens, it floats above the water surface in the shape of arrow 14 and moves forward (in the direction away from the jet port 21).

Therefore, the water flow 14 shown by the arrow pushes the scale 4 in the opposite direction to the tube body 19 of the scale collecting device, thereby impeding the scale collecting function of the scale collecting device. Therefore, the present invention aims to improve the scale collecting function of the scale collecting device by pushing the scale toward the scale collecting device by the water stream discharged from the jet port.

Means for Solving the Problems The present invention provides a method in which the jet port for discharging bath water into the bathtub is directed downward toward the interior of the bathtub, and the water flow discharged from the jet port provides
It is designed to push the scale toward the scale collection device.

Effect: According to the above means, bathtub water is ejected from the jet spout toward the bottom of the bathtub, and the water flow rises along the bathtub wall facing the jet spout, changes direction, and is located on the jet spout side. The flow is directed towards the scum collection device, which acts to carry the scum in the direction of said device. - Embodiment FIG. 1 shows a bathtub water purification device according to an embodiment of the present invention. Parts that are the same as those in the above-mentioned conventional technology are given the same reference numerals, detailed explanations are omitted, and the explanation will focus on the different parts. . 2
2 is a jet nozzle 2 directed downward inside the bathtub 9.
Receiving the bathtub water from the direction o, a water flow shown by an arrow 23 is formed.

In the above embodiment, the circulation pump 5 is operated to circulate the bath water 7 through the upper and lower circulation pipes 3.2 as shown by the arrows. When water is ejected from the jet nozzle 20, a negative pressure is generated on the outer periphery due to the jet force, and this causes the circulation path 1
Water in the bathtub 5 is sucked, and bathwater water is spouted into the bathtub 9 from the jet port 22.

Then, as the water in the circulation path 15 is circulated, the pipe body 19 of the scum collection device moves to the water surface, and the water intake port 1 at the tip moves to the water surface.
The scale 4 is inhaled from the bath water 9a along with the bath water 7, and when the bath water 7 passes through the filter 16, the scale 4 is separated and removed.The remaining bath water 7 passes through the circulation path 15 and passes through the jet nozzle 20 and the jet port 22 again. It passes through and squirts into the bathtub 9.

At this time, since the jet port 22 is facing downward, the jet port 22
The water stream 23 discharged from 2 flows toward the bottom of the bathtub 9,
Then, it flows on the bathtub wall surface opposite to the bathtub wall where the scale collection device is installed, floats, and flows on the water surface in the direction of the pipe body 19 of the scale collection device, and the scale 4 along with the bath water 7 flows in the direction of the pipe body 19. Since it flows, it is inhaled more efficiently and the scale 4 can be sucked out.

The above circulation is repeated, and the scale 4 is passed through the filter 16.
It can be removed with

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, scale floating on the water surface and hair sinking to the bottom of the bathtub are carried toward the scale collecting device by the water flow discharged from the jet port. This has the advantage of improving dirt collection efficiency and speeding up the collection action. Another advantage is that the dirt does not stay on the water surface and becomes less noticeable, making bathing more pleasant.
