It is comprised by the upper chamber 53b in the member 37 partitioned off by the wall 36b.

  The operation of the tracking apparatus having the above configuration will be described. First, the memorial will be described. When the user turns on a button (not shown) for instructing the user, the controller 16 drives the pump 11 in response to this and performs combustion in the combustion section 12a. At this time, the electromagnetic on-off valve 21 is opened and the electromagnetic on-off valve 22 is kept closed.

  When the pump 11 is driven, the hot water in the bathtub 2 is sucked from the suction port 41 of the connection unit 30, passes through the suction passage 51, reaches the pump 11 through the return pipe 10 a connected to the joint 25 a, and then comes out of the pump 11. The hot water is heated by the heat exchanger 12b, passes through the forward pipe 10b, is discharged from the first discharge port 42 through the joint 25b and the first discharge passage 52 of the connection unit 30, and returned to the bathtub 2. Since the discharged hot water is discharged downward into the bathtub 2, a stirring effect can be obtained. At the time of the remedy, since the solenoid valve of the air supply valve 14 is closed, external air supply is not performed.

  Next, the fine bubble supply will be described. The controller 16 executes the supply of fine bubbles in response to the user turning on a button for instructing supply of fine bubbles. More specifically, the pump 11 is driven, the on-off valve 21 is closed, the on-off valve 22 is opened, and the electromagnetic valve of the air supply valve 14 is opened.

  Due to the suction action of the pump 11, the hot water in the bathtub 2 is sucked from the suction port 41 of the connection unit 30, and reaches the pump 11 through the suction passage 51 and the return pipe 10 a, and further from the pump 11. 10 b passes through the branch pipe 10 c from the branch point P, and is discharged from the second discharge port 43 through the second discharge passage 53 of the connection unit 30.

The check valve of the air supply valve 14 is opened by the negative pressure generated by driving the pump 11 and supplies outside air to the memory circuit 10. The pump 11 sucks the outside air from the air supply valve 14 together with the hot water in the bathtub 2, makes the air fine bubbles, further pressurizes it, and dissolves it in the hot water. At this time, since the vane pump is used as the pump 11, the air can be efficiently dissolved.
In the hot water discharged from the pump 11, bubbles remaining without being dissolved are removed by the air vent valve 15.

  As described above, hot water in which air has been dissolved passes through the orifice 35h and the gap 35i when passing through the second discharge passage 52 of the connection unit 30. The upstream side of the orifice 35h and the gap 35i is maintained at a high pressure and the air remains dissolved, but the pressure is rapidly reduced on the downstream side thereof, and the dissolved air becomes fine bubbles at once. The hot water containing fine bubbles is supplied into the bathtub 2 from the second discharge port 43 through the chamber 53b.

  The hot water containing fine bubbles spreads in the chamber 53b far wider than the communication passage 35j connected to the first discharge port 42, and further into the bathtub 2 from the second discharge port 43 having a larger opening area than the first discharge port 42. In addition, since the hot water flow is directed in the same direction as the rising direction of the fine bubbles, that is, upward, the fine bubbles can be supplied efficiently.

  The controller 16 is operated later, and selectively executes tracking and supplying fine bubbles with priority given to other buttons among the tracking button and the fine bubble supplying button.

  In the first embodiment, since the branch point P and the on-off valves 21 and 22 are provided in the vicinity of the connection unit, the branch pipe 10c can be shortened and the piping structure can be simplified. The branch point P may be constituted by a bifurcated joint, and one path of this joint may be a part of the memorial circuit and the other path may be a branch circuit.

  Next, another embodiment of the present invention will be described. Constituent parts corresponding to the preceding embodiments in these embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  Since the fine bubble supply of the second embodiment is the same as that of the first embodiment, the description thereof is omitted. When performing the tracking, the auxiliary pump 12e is driven together with the pump 11. The heat medium circulating in the auxiliary circulation circuit 12d receives the heat of combustion of the combustion unit 12a in the heat exchange unit 12b, and gives heat to the hot water in the bathtub 2 that circulates in the memory circulation circuit 10 in the liquid / liquid heat exchange unit 12c. .

Although the discharge pressure of the pump 11 composed of the vane pump is high, in the second embodiment, it is provided on the downstream side of the heat supply unit 12 ′. Can do.
In the arrangement of the pump 11 according to the second embodiment, the hot water passing through the heat supply unit 12 ′ has a negative pressure and may be boiled when directly receiving combustion heat. However, since hot water does not receive combustion heat directly and receives heat in the liquid / liquid heat exchanging section 12c, boiling does not occur, and chasing can be performed efficiently.

  In the second embodiment, when supplying fine bubbles, the melted air discharged from the pump 11 does not pass through the heat supply unit 12 ′ and reaches the connection unit 30 with a small pressure loss. It can be carried out.

  The third embodiment shown in FIG. 10 has the same configuration as the first embodiment except for the switching means. Specifically, a three-way valve 25 as a switching unit is provided between the air vent valve 15 and the heat supply unit 12 on the upstream side of the heat supply unit 12. One outlet port of the three-way valve 25 is connected to the heat supply unit 12, and the other outlet port is connected to the joint 25c (see FIG. 1) of the connection unit 30 via the branch pipe 10c without passing through the heat supply unit 12. The

  Even in the third embodiment, since hot water does not pass through the heat exchanging unit 12 when supplying fine bubbles, pressure loss is small. When the three-way valve 25 is provided in the remedy unit 1a, the branch pipe 10c becomes longer, but the structure around the bathtub 2 can be simplified and the control by the control 16 becomes easy.

  The fourth embodiment shown in FIG. 11 is the same as the second embodiment in that the pump 11 and the like are arranged on the downstream side of the heat supply unit 12 ′, and a three-way valve 25 as a switching means is placed in the remedy unit 1a. The arrangement is the same as in the third embodiment.

  The present invention is not limited to the above-described embodiment, and various aspects can be made. For example, in the first and second embodiments, since the flow resistance of the second discharge passage is larger than the flow resistance of the first discharge passage, the on-off valve 22 may be omitted. Further, a three-way valve may be provided at the branch point P instead of the on-off valves 21 and 22.
