Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for circulating bath water to generate bubbles and at the same time filtering the bath water.

BACKGROUND ART When bath water is circulated by a pump, bubbles are generated from a spout having a bubble generating device and at the same time, the bath water is filtered via a filtration device.

Hereinafter, a conventional bubble bath device will be explained based on the drawings.

A spout 3 equipped with a foam generator is installed.

A suction pipe 5 is connected to the suction port 2, a discharge pipe 7 is connected to the ejection port 3, and the first stage 6-1 of the two-stage pump 6 is connected to form a circulation path for generating bubbles. An air hose 4 for air inflow is attached to the spout 3. Next, the water channel for filtering the bathtub water is the second stage 6-2 of the pump 6.
It is formed by a filtration inflow pipe 8 that connects the filtration device 9 to the filtration device 9, and a filtration outflow pipe 1o that connects the filtration device 9 and the spout 3.

In the bubble bath device, hot water in the bathtub is sucked through the suction port 2 by the operation of the pump 6, and the hot water is drawn into the suction pipe 5 through the first stage of the Q pump 6-.
Hot water in the bathtub is spouted from a discharge pipe 7 through a spout 3 having a built-in bubble generator. At the time of this spouting, air flows through the air hose 4 by the bubble generator, and hot water containing bubbles is spouted into the bathtub. In other words, it is jet operation.

At the same time, when the pump 6 is operated, the hot water in the bathtub is sucked in by the first stage 6-1 of the pump 6, and some of the hot water is pressurized by the second stage 6-2, passes through the filtration inflow pipe 8, and passes through the filtration device 9. The water flows from the filtration outflow pipe 10 to join the discharge pipe 7 and is ejected from the spout 3 into the bathtub. When hot water in the bathtub passes through the filtration device 9, dirt in the hot water is filtered out.

In other words, it is a filtration operation.

Problems to be Solved by the Invention However, in the above-described structure, when the pump 6 is operated, the jet operation for generating bubbles and the filtration operation for filtering dirt from the bathtub water are carried out at the same time. By operating the pump 6 when performing filtration operation when the bath is dirty, jet operation is also operated at the same time even when not taking a bath.

During this jet operation, air bubbles are ejected and a sound is generated when the air bubbles are ejected, and even if you are not bathing in the bathroom during the filtration operation time (currently about 30 minutes in automatic operation), the sound of air bubbles ejecting occurs and is a problem. be.

The present invention has been made in view of the above problems, and includes an electric valve in the middle of the discharge side pipe connecting the pump and the jet port, and a pipe leading to the filtration device from the middle of the pump and the electric valve. The purpose is to switch between Geno I operation and filtration operation by operating this electric valve, and to prevent jet operation from operating during filtration operation.

Means for Solving the Problems In order to solve the above problems, the present invention provides an electric valve in the middle of the discharge side pipeline, and at the same time provides a pipeline from the pipeline connecting the pump and the electric valve to the filtration side. By changing the position of the electric valve, hot water in the bathtub discharged from the pump can be switched to the filtration side.

Effect: Due to the structure described above, the valve position of the electric valve changes, so that no bubbles are generated in the jet operation, that is, the bubble generator, during filtration operation, and when the filtration operation is performed after bathing, the sound of bubble generation is eliminated. It is possible to filter bathtub water without causing any problems.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. Second
The figure is a schematic diagram of the bubble bath device of the present invention.

In FIG. 2, reference numeral 12 denotes a bathtub, and a hole in the side of the bathtub 12 is provided with a suction port 13 and a spout 23 equipped with a bubble generator. A suction pipe 14 is connected to the suction port 13, a discharge pipe 17 is connected to the jet port 23, and the suction pipe 14 is connected to the pump 1.
5, and the discharge pipe 17 is connected via an electric valve 18 to a branch pipe 16 connecting the electric valve 18 and the discharge port of the pump 15, thereby forming a circulation path for bubble generation, that is, jet operation. An air hose 22 is attached to the spout 23 to allow air to flow in. Next, the water channel for filtering the bath water is a branch pipe 1 that connects the pump 16 and the electric valve 18.
It is formed by a filtration inflow pipe 19 to the filtration device 2° branched from 6 and a filtration outflow pipe 21 discharged from the filtration device 2o,
The filtration outflow pipe 21 is arranged so as to return to the discharge pipe 17 that connects the electric valve 18 and the spout 23 . Figure 3, Figure 4,
FIG. 6 is a diagram showing the operating state of the bubble bath device when the operation of the electric valve 180 valve 18-a is changed. Third, in the figure, the bathtub water sucked in from the suction port 13 by the operation of the pump 15 flows into the suction pipe 14 and flows out from the branch pipe 16, and at this time, the valve 18-a of the electric valve 18 flows into the discharge pipe 17. Since the water channel is open, the discharge pipe 1 is opened as shown by the arrow.
7 and is squirted into the bathtub. In other words, it is in a jet operating state.

In this state, the pressure at the inlet and outlet of the filtration inflow pipe 19 and the filtration outflow pipe 21 to the filtration device is substantially the same, so no water flows into the filtration device 2o. In FIG. 4, the valve 18- of the electric valve 18
Since a is in a state where the waterway to the discharge pipe 17 is closed,
The bathtub water discharged from the pump 16 is passed from the branch pipe 16 through the filtration inflow pipe 19 and then through the filtration device 20 to the filtration outflow pipe 21.
It is ejected into the bathtub via the discharge pipe 17. In other words, it is in a filtration operation state. In this state, the bathtub water is filtered by the filter device 2.
The bath water is purified by passing it through the bathtub water to filter dirt and return it back into the bathtub, thereby performing a circulation operation. In addition, the amount of water flowing to the filtration device 2o is approximately 10 to 1 in order to maintain filtration performance.
Since it is set so that only an amount of water of about 51/rmn flows, it is possible to operate in a state where almost no bubbles are ejected when the water is ejected from the ejection port 23. In FIG. 5, the operation of the valve 18-a of the electric valve 18 is rotated at a constant cycle (valve 18-a rotates once every 2 seconds) to repeatedly open and close the water channel of the discharge pipe 17, during jet operation. Drop-out operation becomes possible. Therefore, by changing the operating position of valve 1-a of the motor-driven valve 18, it is possible to switch between Geno) operation, filtration operation, and intermittent jet operation.

Effects of the Invention As is clear from the above explanation, according to the present invention, dedicated operating states of jet operation and filtration operation are possible by the operation of the electric valve, and when the bathtub water is noticeably dirty after bathing and filtration operation is performed. , without jet operation, i.e., there is no bubble state, so no sound is generated when bubbles are generated, allowing quiet filtration operation, and at the same time, filtration operation can be easily performed by simply changing the position of the electric valve. Therefore, there is no need to use a complicated two-stage pump, which has great cost advantages and is highly effective. In addition, the ability to control the operation of the electric valve and the ability to perform various operating specifications increases the features of the bubble bath device.
