Foreign matter such as scale floating in the bathtub is captured by a filter 5, and the purified bathtub water 6 is spouted back into the bathtub 3.

Problems to be Solved by the Invention However, with the above configuration, the dry water that falls from the faucet 2 in the conventional example shown in FIG. However, there is a problem in that the faucet 2 must be installed separately. In addition, in the conventional example shown in FIG. 4, the filter 5 is installed outside the bathtub 3, so it is difficult to take measures when the filter becomes clogged, and the bathtub water 6 discharged from the circulation pump 4 is returned to the original bathtub 3.
Since the hot water is ejected into the bathtub water 6 inside, there is a problem in that it is not possible to supply hot water into the bathtub in a planar shape similar to the above-mentioned natural waterfall or spring water.

In view of the above-mentioned problems, the present invention supplies water to a bathtub freely in a three-dimensional or planar form like a natural waterfall or a spring water, and has a water supply device integrated with the hot water supply device for multi-purpose use. The present invention provides a bathtub water supply device that allows for water purification.

In order to solve the above-mentioned problems, the bathtub water supply device of the present invention includes a circulation pump and a discharge port for spouting hot water into the bathtub, and a discharge port that is connected to the discharge port. an upward flow channel, a first check valve of the upward flow channel, an outlet provided at the upper part of the upward flow channel, a jet port provided in front of the discharge port, and a detachable closing means therefor. and a bathtub water suction passage provided around the discharge valve opening, its second check valve, and its filter, the discharge opening facing inside, and an upward flow passage, a jet opening, and a bathtub water suction passage. It is equipped with branch chambers that are connected to each other to separate the flow.

Effects According to the present invention, with the above-described configuration, the outlet is provided in the upper part of the bathtub, so that hot water can freely fall into the bathtub from the outlet.

Furthermore, since a filter can be installed inside the bathtub, it is possible to treat clogged filters in the bathroom, as well as to purify the bathtub water and to perform pine surges on the body with a jet of bathtub water from the jet spout.

At this time, negative pressure is generated in the branch chamber 25 by the bath water 12 discharged from the discharge port 16 at a high flow rate.

This negative pressure leads to an upward water passage 19 that leads to the branch chamber 25.
A force is generated to suck air and hot water from the bathtub water suction passage 27, but since the check valve A20 closes the upward water passage 19, suction is drawn only from the bathtub water suction passage 27. Therefore, the bathtub water 12 passes through the filter 28, flows into the bathtub water suction passage 27, and the branch chamber 25, joins with the bathtub water 12 discharged from the above-mentioned discharge port 16, and flows from the spout port 17 into the bathtub 1.
It ejects into the air as a jet. As shown in Part 2, when the blocking means 18 is opened, the filter 28 captures the scales and purifies the bath water 12, and at the same time, when the jet is applied to the bather's body, it also produces a pine surge effect. .

Effects of the Invention As described above, the present invention provides a circulation pump for spouting hot water into a bathtub, a discharge port, an upward flow channel provided in communication with the discharge port, and a first check valve for the upward flow channel. an outflow port provided at the top of the upward flow channel for sending hot water to the bathtub; a jet port provided in front of the discharge port; a closing means detachable from the jet port; and a bathtub provided around the discharge port. A water suction passage, a second check valve for the bathtub water suction passage, a filter provided in the bathtub water suction passage, and a filter provided in the bathtub water suction passage, with the discharge port facing inside, and an upward flow passage, a jet spout, and a bathtub water suction passage, respectively. It is equipped with connected branch chambers, and hot water can be poured into the bathtub from the outlet, so it is possible to create a free flow like a waterfall from the outlet, and create a three-dimensional shape like a natural waterfall or spring water. It is possible to supply hot water into the bathtub with a circular or planar flow. The pine surge effect caused by the jet stream from the single jet port and the purification function of the bathtub water by the filter can be achieved by simply switching the blocking means. Furthermore, it is also possible to extremely miniaturize and integrate the two conventional hot water supply and filtration technologies.
