Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water circulating apparatus, and more particularly to a bath water circulating apparatus having a function of cleaning the inside of an air side pipe for taking air into circulating bath water.

[0002]

2. Description of the Related Art FIG. 7 is a schematic view of bathtub piping of a conventional jet bath. In the conventional bathtub piping of the jet bath, the water side piping 5 for sending the bathtub water sent from the water suction port 2 to the pump 4 via the water suction pipe 30 to the water discharge port 3 by the system, and the air intake port 6 It can be classified as an air side pipe 7 that sends the sucked air to the water discharge port 3. The broken line arrow B in the figure indicates the flow of water, and the solid line arrow C indicates the flow of air. Here, since the bath water from the pump 4 passes through the water side pipe 5, stains such as scale are unlikely to adhere to the inside of the pipe, while the air side pipe 7 is, for example, in the air side pipe 7 when the jet operation is stopped. The bath water may flow back to a portion of the bathtub 1 that is located at a position lower than the water level of the bath water, and stains such as scales are likely to adhere to the air side pipe 7. In addition, the flow of hot and cold water inside the air side pipe 7 is small, the hot and cold water is stagnant, and is easily contaminated by scales and wastes, which adversely affects the flow of air, so that cleaning is required.
Conventionally, the work of disassembling the bathtub pipe and injecting into the air side pipe 7 something having a cleaning action such as a detergent into the air side pipe 7 has been performed.

The valve 9b is provided. Further, the bypass passage 8 is formed in a generally U-shape in a plan view extending horizontally over substantially the half circumference of the outer peripheral wall of the bathtub 1, and one end thereof is connected to a branch portion between the water side pipe 5 and the bypass passage 8. The other end is branched and connected in the middle of the horizontal portion of the air side pipe 7. Other configurations are similar to those of the embodiment of FIG.

Therefore, during the normal jet operation, the first switching valve 9a is switched to the water side pipe 5 side, and the bypass passage 8
The bath water to be stopped is stopped, the bath water discharged from the pump 4 is supplied to the water side pipe 5, and is sprayed into the bath 1 from the water discharge port 3. At this time, the second switching valve 9b opens the air intake port 6 side, so that the air sucked from the air intake port 6 flows into the air side pipe 7 and is sent to the water discharge port 3 of the bath 1 to discharge the air. A jet jet is discharged from the water port 3. on the other hand,
During pipe cleaning, the first switching valve 9a is switched from the water side pipe 5 side to the bypass line 8 side to supply the bath water from the pump 4 to the bypass line 8. At the same time, the second switching valve 9b
Closes the air intake port 6 side, and the bath water supplied to the bypass passage 8 passes through the air side pipe 7 from the water outlet 3 to the bathtub 1.
The water is sprayed inward and the backflow of bath water to the air intake port 6 is prevented. Therefore, as in the embodiment of FIG. 1, jet water passes through the air-side pipe 7 with a strong force, so that stains in the air-side pipe 7 such as scales and waste products from the human body are washed away, and the air-side pipe 7 In addition to the effect of easily cleaning the inside of the pump 7, it is not necessary to provide a jet discharge port for connecting the bypass passage 8 to the pump 4, and there is an advantage that the structure of the pump 4 can be simplified.

At this time, the first check valve 10a on the air side pipe 7 side passes air in the direction of arrow F in FIG. 6 (a). In addition, at this time, the second check valve 10b is used to discharge from the discharge opening 12 of the bath 1 to the cleaning drain 11
Since the backflow of bath water into the interior is blocked, the air intake port 6
Only the air from the inside flows into the air side pipe 7 and is sent to the water outlet 3 of the bathtub 1, and the jet jet is discharged from the water outlet 3. On the other hand, at the time of cleaning the pipe, the lid 13 is attached to the water outlet 3 to close the water outlet 3 as shown in FIG. As a result, the bath water discharged from the pump 4 into the water side pipe 5 is stopped by the lid 13 of the water discharge port 3 and sent into the air side pipe 7 along the arrow direction of FIG. At this time, FIG.
As shown by the arrow H in (a), the bath water in the air side pipe 7 passes through the second check valve 10b, is discharged from the discharge opening 12, and is jetted into the bath 1. Further, at this time, the first check valve 10a on the air side pipe 7 side prevents the backflow of the bath water, so that the bath water is prevented from being ejected from the air intake port 6.

Therefore, as in the embodiment of FIG. 1, jet water passes through the air-side pipe 7 with a strong force, so that dirt in the air-side pipe 7 such as scales and waste products from the human body is washed away. In addition to the effect of easily cleaning the inside of the air side pipe 7, the check valves 10a, 1 as the switching means 10 are provided.
When 0b is used, the switching operation of the flow path becomes easier, and in addition, the discharge opening 12 is provided near the air intake port 6.
By arranging, there is also an advantage that the distance of the cleaning drainage channel 11 can be shortened and the structure of the bathtub piping can be simplified.

In FIG. 6A, two check valves 10a,
Although 10b is used, as shown in FIG. 6 (b), a flow path switching valve 10c such as a three-way valve may be provided at a branch portion between the cleaning drainage channel 11 and the air side pipe 7. In this case, when the flow path switching valve 10c is switched to the air intake port 6 side during jet operation, the air from the air intake port 6 can be sent to the water discharge port 3 through the air side pipe 7, and the flow path can be washed during pipe cleaning. The switching valve 10c from the air intake port 6 side to the cleaning drainage channel 1
When switching to the 1 side, the bath water can be supplied from the cleaning drainage channel 11 to the spout 3 while preventing backflow of the bath water to the air intake port 6, and switching between normal operation and pipe cleaning becomes easy.
