The other ends are connected to the return ports 3 of the bathtub 1, respectively. 'Also, insert the suction pipe 9 while keeping a gap inside the return circulation vibrator 9.
The suction pipe 9a has a partial opening facing the return port 3 of the bathtub 1, and the other end passes through the middle of the return circulation pipe 9 and is connected to the filter 17 in the bathtub water purification device 15. The operation of the bathtub water purification device configured as described above will be described below.

First, the bathtub water is heated in the bath-refreshing heat exchanger 14, and by utilizing the density difference of the water, the bath-refreshing heat exchanger 14 and the bathtub 1 are connected to each other through the circulation pipes 8.9 for going and returning. natural circulation between the baths and raise the temperature to the appropriate temperature for bathing. And when you take a bath, hair, dirt, and other debris get mixed into the bathtub water. At this time, by operating the circulation pump 16, the bathtub water sucked through the suction pipe 9a is discharged from the nozzle section 10 through the filter 17 and the circulation bonder 16.
Due to the ejector effect, air is attracted by the air pipe 11, becomes a jet stream containing air bubbles 7 through the outgoing pipe 12, and is discharged into the bathtub 1 from the outlet 2 to stir the bathtub water. At this time, the dirt mixed in the bathtub water is sucked back through the return 903 and sent to the filter 17 through the suction pipe 9a for collection, and the cleaned bathwater is returned to the circulation pump 16 and circulated.

Problems to be Solved by the Invention However, in the above configuration, the bathtub water flows through the outlet 2.
Since the water is discharged from the bathtub and sucked by the circulation pump 16 from the return port 3, the bathtub water only circulates within the bathtub 1 as shown by the arrow 5 in Fig. 2, and removes hair, dirt 6, etc. floating in the upper part of the bathtub water. Since suction cannot be achieved reliably, there is a problem in that the bathtub water cannot be purified properly.

In view of the above-mentioned problems, the present invention provides a bathtub water purification device that reliably circulates the upper layer water containing floating matter above the water surface, collects grime, etc. in a filter, and reliably purifies the bathtub water. It is something.

Means for Solving the Problems In order to solve the above-mentioned problems, the bathtub water purification device of the present invention includes a nozzle for spouting bathwater into the bathtub using a circulating pump, and a nozzle for squirting bathwater into the bathtub by a jet flow from the nozzle. It has a filtration part installed in an attraction flow path that attracts water, and a hollow pipe that communicates with the suction side of this filtration part and floats near the bottom of the bathtub water surface by the bathtub water flow. It is equipped with water flow guide blades.

Operation The present invention has the above-described configuration, and the bathtub water is jetted into the bathtub from the nozzle. At this time, an ejection effect occurs due to the discharge flow from the nozzle, and the induced flow path begins to suck the bathtub water through the filtration section. When the induced flow occurs due to this effect, the hollow pipe provided in the induced flow path floats up while rotating and sucks in the upper layer water of the bathtub water. By inhaling this upper layer water, hair, dirt, etc. floating on the upper surface of the bathtub water are reliably passed through the filtration section and filtered together with the upper layer water.

EXAMPLE Hereinafter, a bathtub water purification device according to an example of the present invention will be described with reference to the drawings.

In the figure, 1 is a bathtub, 2 is a return port provided on the side wall of the bathtub,

It communicates with the outgoing circulation pipe 15.

Reference numeral 5 denotes a jet port, which is provided with a gap 6a between it and the nozzle 4. Reference numeral 7 denotes a filtration section, which is made of materials such as wire mesh, sand, and nonwoven fabric, and has an outlet side communicating with the gap 6a, and an inlet side communicating with a fixed induced flow path 8. The induced flow path 8 has an open end facing above the bathtub 1, and a hollow pipe 9 is disposed around the outer periphery thereof with a gap 9a so as to be slidable up and down. Reference numeral 9b denotes water flow guide vanes, and a plurality of them are provided inside the upper end opening of the hollow pipe 9. 13 is a circulation pipe on the return side. 22 is a heat source device, which has a bath reheating heat exchanger 17, and has a return circulation pipe 13 on the inlet side and a circulation pump 16 on the outlet side.

It is connected to a hot water tap 23 in a bathroom or the like. The other is solenoid valve 1
9 and a hopper 20, it is connected to a bath reheating heat exchanger 17.

The operation of the bathtub water purification device configured as described above will be explained below with reference to FIGS. 1, 2, and 3.

First, FIG. 1 shows the bathtub water purification device of the present invention, in which hot water is poured into the bathtub 1 by opening the electromagnetic valve 19, and the hot water heated to an appropriate temperature by the hot water supply heat exchanger 18 is poured into the hopper. 20 to the bath reheating heat exchanger 17, which fills the bathtub 1 through each circulation pipe 13.15. When the bathtub water temperature decreases after taking a bath, the circulation pump 16 is operated to operate the return pipe 2, the return circulation pipe 13, the bath reheating heat exchanger 17, the forward circulation pipe, the nozzle 4, the jet port 5, and the bathtub. By circulating the bath water in the order of 1 and heating it at the same time with the bath reheating heat exchanger 17, the temperature of the bath water can be raised and bathing is possible. During this bathing, hair and dirt get mixed into the bathtub water.

These hairs and dirt 11 are floating in the upper layer of the bathtub water 10. The circulation pump 16 is operated, the bath water is sucked in from the return port 2, the return circulation pipe 13, the bath reheating heat exchanger 17,
It passes through the outgoing circulation pipe 15, is discharged from the nozzle 4, and is ejected from the jet outlet 5 into the bathtub. When this nozzle 4 discharges a high-speed flow to the jet port 5, the water in the gap 6a is attracted by the attractive force caused by the ejector action, sucks the bath water from the induced channel 8, and starts flowing through the filter part 7. . Before the start of suction, the hollow pipe 9 is submerged, but when the bath water begins to flow into the hollow pipe 9, rotational force is applied to the hollow pipe 9 by the water flow guide vane 9h on the inlet side, and the hollow pipe 9 begins to rotate. Next, due to the pressure difference between the outer circumferential water pressure of the hollow pipe 9 and the water flowing inside the hollow pipe 9, it floats up while rotating to the top of the bathtub water, and when it is a few feet below the water surface, the pressure difference balances out with the own weight of the hollow pipe 9. state, and the hollow pipe 9 stops floating. With this, the hollow pipe 9 continues to suck in the upper layer water of the bathtub water, thereby reliably sucking in hair, dirt, etc. floating in the upper layer of the bathtub water. The hair/dirt 11 inhaled in this way is filtered by the filtration part 7 in the purification unit 3, and
It is returned to the bathtub 1 from the spout 5 by the ejector action of laa.

As described above, according to this embodiment, the induction passage that uses the ejector action of the jet from the nozzle 4 is opened toward the upper part of the bathtub through the filtration part 7, and the hollow pipe 9 can be slid around the outer circumference of the induction passage. Furthermore, by providing a water flow guide vane inside the upper end of the hollow pipe, when the circulation pump is operated, the hollow pipe 9 floats up to the top of the bathtub water while rotating, and the upper layer water of the bathtub water can be sucked. Hair, dirt 11, etc. floating in the air can be sucked in and collected in the filtration part 7, and the rotating force of the hollow pipe can easily prevent foreign objects from getting caught in the gap 9b between the hollow pipe and the opening. Since the hollow pipe 9 can be removed quickly, floating of the hollow pipe 9 can be ensured.

Effects of the Invention As described above, the present invention uses a circulating pump to eject bathwater from a nozzle, generates an induced flow by an ejector action, provides a filtration section in the induced flow path, and has a gap around the outer periphery of the induced flow path. A hollow pipe is provided, and a plurality of water flow guide vanes are provided inside the top of the pipe, so the hollow pipe rotates and floats to the top of the bath water due to the induced flow caused by the ejector action generated by the operation of the circulation pump. Since the upper layer water of the bathtub water is inhaled, hair, dirt, etc. floating in the upper layer water can be easily inhaled and collected in the filtration part, and the rotational force generated when the hollow pipe floats makes it possible to separate the hollow pipe from the surface. Since it is possible to eliminate the possibility of foreign objects getting caught in the gap between the openings, the floating of the hollow pipe can be ensured.
