Description

  The present invention relates to a jet bath system having a configuration for jetting a bubble-containing jet into a bathtub.

  There is a bathtub bubble ejection device that circulates bathtub water and applies a jet flow in which bubbles are mixed into the bathtub water to the surface of the user's body in the bathtub to give a massage effect or the like (for example, Patent Documents 1 and 2). ). Such an apparatus generally includes an air pipe for supplying air, and mixes air with bathtub water to eject a jet (referred to as “blow operation with air” for convenience of explanation) and air to the bathtub. There may be a case where an operation of jetting a jet without mixing with water (referred to as “blow operation without air” for convenience of explanation) may be selected.

  In this case, since the air is mixed into the bathtub water during the “blow operation with air”, a so-called “breaking sound” of air such as “goo” or “boo” is generated from the air pipe. Therefore, a certain amount of noise is generated during the operation of “blow operation with air”.

However, if the “blow operation with air” is performed in a state where water is accumulated in the air pipe, further loud noise may occur for a long time. The reason for the generation of the sound is that, in addition to the sound of entraining the air at the junction of the air pipe and the blow pipe, the sound of the air entraining the water remaining in the air pipe is also generated.

Department and front A control unit that controls the pump, and when the control unit starts the blow-with-air operation with the on-off valve opened, before the pump is driven at the rated operation, The jet bath system is controlled so as to be driven at a higher rotational speed.
According to this jet bath system, when starting the "blow operation with air" that drives the pump with the open / close valve opened, the control unit was driven at a higher rotational speed than the rotational speed at the rated operation. Later, the pump is driven at rated operation. Therefore, when the “blow operation with air” is started, the water accumulated in the air pipe that causes the generation of sound can be eliminated at once in the blow pipe section. Therefore, there is no possibility that loud noise will be generated for a long time.

In addition, according to a second aspect, in the first aspect, the on-off valve is disposed so that the path of the second air piping portion is shorter than the first air piping portion. This is a featured jet bath system.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a schematic diagram showing the configuration of a jet bath system according to a first embodiment of the present invention.
Moreover, FIG. 2 is the schematic diagram which looked at the jet bath system concerning this embodiment from the plane direction. Moreover, FIG. 3 is the schematic diagram which looked at the jet bath system concerning this embodiment from the side surface direction.

  The jet bath system according to the present embodiment is mainly jetted from the bathtub 1, the jet jet part for sucking the bathtub water in the bathtub 1 and ejecting the bathtub water again from the nozzles 12, 16 and the nozzles 12, 16. And an air supply unit that allows air bubbles to be mixed into the jet.

First, the jet ejection part will be described with reference to the drawings.
The bathtub 1 has a suction port 5 for storing the bathtub water and sucking the stored bathtub water. In the present specification, “water” includes not only cold water but also heated hot water. The suction port 5 is formed in the long side bathtub wall in the bathtub 1, and the suction port 5 is connected to the suction port of the pump 7 through the water conduit 6. When the pump 7 is driven, the bathtub water stored in the bathtub 1 is sucked from the suction port 5 into the water conduit 6.

  When considering a normal bathtub having a pair of opposed long-side bathtub walls and a pair of opposed short-side bathtub walls, a bather generally has a back on one of the pair of short-side bathtub walls. When the suction port 5 is formed on the short side bathtub wall, the suction port 5 is blocked by the back or sole of the bather. There is a concern that an excessive load is applied to the pump 7. Therefore, it is desirable to form the suction port 5 in the long side bathtub wall which is not easily blocked by a part of the body of the bather.

  A discharge pipe section 8 is connected to the discharge port of the pump 7, and two jet supply systems are connected to the discharge pipe section 8 via a three-way valve 9 as a switching valve in the present embodiment. . These two jet supply systems are provided in two branches with respect to the discharge pipe section 8, and each system is not connected to other systems and can perform jet jetting operation independently.

  The first jet supply system includes a first blow pipe section 11 connected to the discharge pipe section 8 via the three-way valve 9, and a discharge pipe section 8 and a first blow pipe section discharged from the pump 7. And a first nozzle 12 capable of ejecting pressurized bathtub water guided to 11 into the bathtub 1. As for the 1st blow piping part 11, the downstream is branched into two, and the 1st nozzle 12 is connected to the branch destination, respectively.

  The second jet supply system includes a second blow pipe section 15 connected to the discharge pipe section 8 via the three-way valve 9, and a discharge pipe section 8 and a second blow pipe section discharged from the pump 7. And a second nozzle 16 capable of ejecting the pressurized bathtub water guided to 15 into the interior of the bathtub 1. As for the 2nd blow piping part 15, the downstream is branched into two, and the 2nd nozzle 16 is connected to the branch destination, respectively.

  Each system may have only one nozzle. In that case, each of the blow pipe portions 11 and 15 does not need to be branched. Alternatively, each system may have three or more nozzles. In the present embodiment, for example, the two first nozzles 12 are attached to one short side bath wall 2a, and the other short side bath wall 2b facing the short side bath wall 2a has, for example, two second nozzles. Two nozzles 16 are attached.

  The pump 7 and the three-way valve 9 are controlled based on a signal from the control unit 21 in response to an operation of the operation unit 22 by the user. When the jet flow is ejected from the first nozzle 12 based on the control signal by the user's operation, the three-way valve 9 is connected to the discharge line portion 8 connected to the discharge port of the pump 7 and the first nozzle 12. In the “first position” where the first blow piping unit 11 communicated and the second blow piping unit 15 connected to the second nozzle 16 and the discharge pipe unit 8 are blocked. Switch. Then, the pressurized bath water sucked from the suction port 5 and pressurized by the pump 7 is guided through the first blow piping section 11 and is ejected from the first nozzle 12 into the bath water.

  On the other hand, when the jet flow is ejected from the second nozzle 16 based on the control signal by the user's operation, the three-way valve 9 is connected to the discharge pipe portion 8 and the second blow pipe connected to the second nozzle 16. The unit 15 is communicated, and the first blow piping unit 11 connected to the first nozzle 12 and the discharge pipe unit 8 are switched to the “second position”. Then, the pressurized bath water sucked from the suction port 5 and pressurized by the pump 7 is guided through the second blow pipe section 15 and is ejected from the second nozzle 16 into the bath water.

  That is, when the pump 7 is driven, the first jet supply system having the first nozzle 12 and the second jet supply system having the second nozzle 16 do not communicate with the discharge side of the pump 7 at the same time. Only one of the systems communicates with the discharge side of the pump 7 and a jet is ejected from only one of the first nozzle 12 and the second nozzle 16.

Next, the air supply unit will be described with reference to the drawings.
In the bathtub rim 3 provided around the upper edge of the inner tank of the bathtub 1, the long side bathtub wall in which the suction port 5 is formed, and the short side bathtub wall 2 a in which the first nozzle 12 is provided An air intake port 41 is formed in the vicinity of the corners.

  A first air piping section 32 is connected to the air intake port 41, and a second air piping section 35 is connected to the first air piping section 32 via an on-off valve 31 that opens and closes the air flow path. ing. Further, the first air piping portion 32 communicates with the atmosphere via the air intake port 41. The second air piping part 35 is branched into two on the downstream side, and is connected to each of the two second blow piping parts 15. Note that the second air piping unit 35 may be connected to each of the two second nozzles 16. The on-off valve 31 may be an electrically driven on-off valve such as an electromagnetic valve, or may be a manually driven on-off valve.

  There is a possibility that water may accumulate in the second air piping portion 35. If the “blow operation with air” is performed in a state where water is accumulated in the air pipe 35, a large noise may be generated. The reason for the generation of the sound is that, in addition to the sound of entraining the air at the junction of the air pipe and the blow pipe, the sound of the air in the air pipe entraining water is also generated.

  The on-off valve 31 is controlled based on a signal from the control unit 21 in response to an operation of the operation unit 22 by the user. Then, by opening the on-off valve 31 based on the control signal, the air intake port 41 provided in the bathtub rim 3, the first air piping portion 32, and the second air piping portion 35 are used for the first operation. The air in the atmosphere can be mixed into the second blow piping section 15 or the second nozzle 16 to eject a bubble-containing jet. According to this, the front side of the body is directed to the short side bathtub wall 2b to which the second nozzle 16 is attached, and the flow rate is reduced with respect to the bather who leans back on the opposite short side bathtub wall 2a. Many powerful jets are erupted and can locally stimulate the bather's lower limbs, for example.

  On the other hand, the on-off valve 31 can be closed based on a control signal generated by a user operation. As a result, the supply of air into the second blow piping section 15 or the second nozzle 16 is cut off, and a jet without bubbles is ejected from the second nozzle 16. According to this, the bather who turned the front side of the body to the short-side bathtub wall 2b to which the second nozzle 16 is attached and leaned back against the short-side bathtub wall 2a on the opposite side, You can feel the feeling of being wrapped gently and relax your mind.

  A third air piping portion 37 is further connected to the air intake port 41, and one end (downstream end) of the third air piping portion is connected to the suction port 5. Further, the third air piping part 37 communicates with the atmosphere via the air intake port 41. For example, when the suction port 5 is blocked by a part of the body of the bather or the hair, and the negative pressure inside the suction port 5 increases, the air intake port 41 and the third air piping part 37 are brought into the interior due to the ejector effect. Air is taken in via As a result, the capacity of the pump 7 is reduced or stopped by sucking the air. As a result, it is possible to avoid unnecessary driving of the pump 7 in a situation where the bath water is not sucked, and the suction force at the suction port 5 is weakened, so that a part of the bather's body, hair, etc. can be easily taken from the suction port 5. Can be released.

  According to the first embodiment of the present invention, when the control unit starts the “blow operation with air” that drives the pump 7 with the on-off valve 31 open, the rotation speed is higher than the rotation speed during the rated operation. After being driven by a number, the pump is driven at rated operation. “Rated operation” is a normal operation in which bath water sucked from the suction port 5 is pressurized by the pump 7 based on a control signal set in advance by the user's operation, and a jet flow is ejected from the second nozzle 16. Refers to driving. “To drive the pump at a higher rotational speed than that during rated operation” means to make it higher than the rotational speed of the pump 7 in the normal operation. By doing so, when the “blow operation with air” is started, the water accumulated in the air pipe, which causes the generation of sound, can be discharged into the blow pipe section at once. Therefore, there is no possibility that loud noise will be generated for a long time.

Next, a second embodiment of the present invention will be described with reference to the drawings.
FIG. 4 is a schematic diagram showing the configuration of the jet bath system according to the second embodiment of the present invention.
In the jet bath system according to the present embodiment, the third air piping section 37 is a pipe from the air intake port 41 to the check valve 43 via the on-off valve 31, and the fourth air piping section 38 is the check valve. The piping from 43 to the 2nd blow piping part 15 is said. This can be considered that the check valve 43 is interposed in the middle of the second air piping part 35 in the jet bath system shown in FIG. The check valve 43 prevents hot water from entering the third air piping portion 37 on the upstream side from the second nozzle 16 via the fourth air piping portion 38. Therefore, dirt such as dirt hardly adheres and accumulates in the third air piping portion 37 upstream of the check valve 43. About another structure, it is the same as that of the structure of the jet bath system mentioned above regarding FIG.

  There is a risk that water may accumulate in the fourth air piping section 38. When “blow operation with air” is performed in a state where water is accumulated in the fourth air piping section 38, a large noise may be generated. The reason for the generation of the sound is that, in addition to the sound of entraining the air at the junction of the air pipe and the blow pipe, the sound of the air remaining in the air pipe is also generated.

  According to the second embodiment of the present invention, when the control unit starts “blow operation with air” that drives the pump 7 with the on-off valve 31 opened, the rotation speed is higher than the rotation speed during the rated operation. After being driven by a number, the pump is driven at rated operation. “Rated operation” is a normal operation in which bath water sucked from the suction port 5 is pressurized by the pump 7 based on a control signal set in advance by the user's operation, and a jet flow is ejected from the second nozzle 16. Refers to driving. “To drive the pump at a higher rotational speed than that during rated operation” means to make it higher than the rotational speed of the pump 7 during normal operation. By doing so, when the “blow operation with air” is started, the water accumulated in the air pipe, which causes the generation of sound, can be discharged into the blow pipe section at once. Therefore, there is no possibility that loud noise will be generated for a long time.

The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention.
