Description

  An aspect of the present invention generally relates to a jet bath system having a configuration in which a jet is jetted into a bathtub.

  There is a bathtub ejection device that gives a massage effect by causing a jet of water to circulate in the bathtub by circulating bath water and hitting the jet against the surface of the human body (Patent Documents 1 to 3). The apparatus described in Patent Document 1 can automatically adjust the strength of the jet jet and the amount of bubbles that adapt to the bath water temperature. Moreover, the apparatus described in patent document 2 can make the jet into which the bubble was mixed in the bath water inhaled with the pump to be ejected in the bathtub. The gas to be taken in is filled in a container in advance, and the container can be easily replaced. Moreover, the apparatus described in Patent Document 3 can prevent bath water or high-humidity air from flowing into the air flow path on the air pump side from the flow control valve.

  Such a bathtub ejection device generally includes a suction port that sucks in bathtub water, a pump that circulates bathtub water, and a nozzle that discharges bathtub water into the bathtub. Then, after the user stops the operation of jetting a jet into the bathtub (herein referred to as “blow operation”) and drains the bathtub water from the bathtub, the bathtub water in the pump is surely drained. However, it is preferable that no water remains in the pump. Therefore, it is preferable that the pump is disposed at a position higher than the suction port.

However, when the pump is disposed at a position higher than the suction port and the pump is disposed at a position higher than the nozzle, the air in the pipe between the pump and the nozzle is not stored when the bath water is stored. There is a problem that the air is not cut off and the edge is cut off with air remaining in the pump. If the air in the pipe between the pump and the nozzle does not escape, if a non-self-priming pump is used, the pump may run idle, and the blow operation performance may be greatly reduced. Normally, piping other than the jet bath system, power supply box, pump, etc. may be installed in the space behind the bathtub, so the fact that the nozzle cannot be placed higher than the pump lowers the degree of freedom in design. This is not preferable.

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 an embodiment of the present invention.
The jet bath system according to the present embodiment mainly includes a bathtub 1, a bathtub water supply unit for sucking the bathtub water in the bathtub 1, and ejecting or supplying the bathtub water again from the nozzle 12 and the discharge unit 16 into the bathtub. 5 is provided with an air supply unit capable of taking in air.

First, the bathtub water supply unit will be described with reference to the drawings.
The bathtub 1 can store bathtub water and has a suction port 5 for 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 first piping unit 8 is connected to the discharge port of the pump 7. The first piping unit 8 is branched into a second piping unit 9 and a third piping unit 10 on the downstream side. The pressurized bath water discharged from the pump 7 and guided to the first piping unit 8 and the second piping unit 9 can be jetted into the bathtub 1 at the downstream end of the second piping unit 9. A nozzle 12 is provided. On the other hand, at the downstream end of the third piping unit 10, pressurized bathtub water discharged from the pump 7 and guided to the first piping unit 8 and the third piping unit 10 can be supplied to the inside of the bathtub 1. The discharge part 16 is connected. The nozzle 12 and the discharge part 16 which a bathtub water supply part has may be one as shown in FIG. 1, or two or more.

  The pump 7 is 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 nozzle 12 based on the control signal by the user's operation, the pump 7 sucks and pressurizes the bathtub water via the suction port 5 and the water conduit pipe portion 6 based on the signal from the control unit 21. Pressurized bathtub water is discharged to the first piping unit 8. And the bathtub water led to the 1st piping part 8 and the 2nd piping part 9 is ejected from the nozzle 12 into bathtub water. Along with this, the pressurized bathtub water discharged from the pump 7 is guided to the first piping part 8 and the third piping part 10, and supplied from the discharge part 16 to the inside of the bathtub 1.

  A bather turning his back to the short side bathtub wall 2a side where the nozzle 12 is provided can obtain a massage effect by receiving a jet flow from the nozzle 12 on a part of the body such as the waist and back. it can. Therefore, the nozzle 12 is provided in the middle part or the lower side with respect to the vertical direction of the bathtub 1. On the other hand, a bather who turns his back to the short side bathtub wall 2a receives the water supplied from the discharge part 16 in a part of the body such as the shoulder, so that the body is gently wrapped in the flow of water. You can experience and relax your mind. Therefore, the discharge part 16 is provided in the upper edge part vicinity of the bathtub 1. FIG. In addition, as will be described in detail later, the discharge unit 16 may be used as an ornamental discharge unit. Even in this case, the discharge part 16 is provided in the vicinity of the upper edge of the bathtub 1.

  After the user stops the operation of jetting a jet from the nozzle 12 into the bathtub 1 (hereinafter referred to as “blow operation” for convenience of explanation) and drains the bathtub water from the bathtub 1, It is preferable that the bath water is drained more reliably and does not remain in the pump 7. Therefore, the pump is preferably provided at a position higher than the suction port 5 as shown in FIG. According to this, after the driving of the pump 7 is stopped, the bathtub water remaining in the pump 7 is drained from the suction port 5 into the bathtub 1 through the water conduit 6. Since the bathtub 1 is provided with a drain port (not shown), the bathtub water drained into the bathtub 1 from the suction port 5 is drained from the drain port to the outside of the bathtub 1.

  The pump 7 is a so-called non-self-priming pump, and pumping cannot be started by automatically performing a priming action by the force of the pump 7 itself. Since the jet bath system according to the present embodiment circulates bathtub water, when the pump 7 is a self-priming pump, it is provided between the “casing” of the pump and the “impeller” provided therein. For example, dust intervening in the bath water may be mixed into the gap, and the seal part of the pump may be damaged. This is because the gap between the “casing” and the “impeller” is smaller in the self-priming pump than in the non-self-priming pump and is set to be minute. Therefore, it is preferable to use a non-self-priming pump in a jet bath system that circulates bathtub water.

Next, an air discharge part is demonstrated, referring drawings.
In the bathtub rim provided around the upper edge of the inner tub of the bathtub 1, the corner of the long side bathtub wall in which the suction port 5 is formed and the short side bathtub wall 2 a in which the nozzle 12 is provided An air intake port 41 is formed in the vicinity (see FIG. 2).

  A first air piping portion 37 is connected to the air intake port 41, and one end (downstream end) of the first air piping portion 37 is connected to the suction port 5. The first air piping part 37 communicates with the atmosphere through the air intake port 41. For example, when the suction port 5 is blocked by a part of the bather's body or the hair, and the negative pressure inside the suction port 5 increases, the air intake port 41 and the first 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.

Next, a specific example of the present embodiment will be described with reference to the drawings.
Drawing 2 is a mimetic diagram which looked at the jet bath system concerning the example of this embodiment from the plane direction.
Moreover, FIG. 3 is the schematic diagram which looked at the jet bath system concerning this example from the side surface direction of the short side bathtub wall.
Moreover, FIG. 4 is the schematic diagram which looked at the jet bath system concerning this example from the side surface direction of the long side bathtub wall.

  In the jet bath system according to this specific example, two nozzles 12 are provided on the side of the short side bathtub wall 2a. Moreover, as mentioned above, the suction port 5 is provided in the long side bathtub wall. As described above with reference to FIG. 1, the pump 7 is preferably provided at a position higher than the suction port 5. Therefore, in the jet bath system according to this example, the pump 7 is appropriately fixed at a position higher than the suction port 5 as shown in FIGS. 3 and 4.

  On the other hand, however, when the pump 7 is provided at a position higher than the nozzle 12, there is a problem that air in the pipe between the pump 7 and the nozzle 12 is difficult to escape when the bath water is stored. More specifically, when the pump 7 is provided at a position higher than the nozzle 12, the air present in at least one of the first piping section 8 and the second piping section 9 is provided at a higher position. It moves toward the pump 7 and is difficult to come out of the nozzle 12 provided at a lower position. If the air in the pipe between the pump 7 and the nozzle 12 does not escape during the blow operation, the pump 7 may run idle, which may reduce the performance of the blow operation.

  Therefore, the jet bath system according to the present embodiment includes the third piping unit 10 branched from the first piping unit 8 and the discharge unit 16 connected to the downstream end of the third piping unit 10. ing. At this time, since the pump 7 is a non-self-priming pump as described above, the water level at which the pump 7 operates normally and can circulate bathtub water (hereinafter referred to as “operable water level” for convenience of explanation). Is set in the pump 7.

  The suction port 5 is provided at a position lower than the operable water level 20 of the pump 7. Further, the pipe line of the first piping unit 8 is provided at a position higher than the operable water level 20 of the pump 7. Furthermore, the discharge part 16 (downstream end of the 3rd piping part 10) is provided in the position higher than the pipe line of the 1st piping part 8. FIG. Therefore, in the jet bath system according to the present embodiment, even if the nozzle 12 is provided at a position lower than the operable water level of the pump 7, at least the first piping unit 8 and the second piping unit 9 are used. The air existing in any of the air escapes from the discharge unit 16 via the third piping unit 10.

  The pipes of the first pipe part 8 and the third pipe part 10 do not have to be higher toward the discharge part 16 as the downstream end, and even if some pipe lines are low, the operable water level 20 of the pump 7 is low. What is necessary is just to be provided in a higher position. Even in this case, the discharge part 16 as the downstream end of the third pipe part 10 is provided at a position higher than the operable water level 20 of the pump 7 and higher than the pipe line of the first pipe part 8. Therefore, the air present in at least one of the first piping part 8 and the second piping part 9 escapes from the discharge part 16. That is, an operable water level can be accumulated in the pump 7.

  According to this, it is possible to prevent the pump 7 from idling without causing air in the pipe between the pump 7 and the nozzle 12 to escape during the blow operation. As a result, it can suppress that the performance of blow operation falls. In addition, since it is possible to alleviate restrictions on the arrangement position, such as the need to arrange the pump 7 at a position higher than the suction port 5 and lower than the nozzle 12, the degree of freedom in design is improved. Can do. Therefore, the arrangement positions of the pump 7 and the nozzle 12 can be set relatively freely.

  As shown in FIGS. 3 and 4, the discharge unit 16 is provided in the vicinity of the upper edge of the bathtub 1, and a pillow 18 is provided on the discharge unit 16. On the other hand, an overflow port 3 that regulates the stored water level of the bath water is provided above the suction port 5 and in at least one of the long side bath walls of the bath 1. The discharge part 16 is provided above the overflow port 3 and at the upper edge part on the short-side bathtub wall 2a side. However, the installation form of the discharge unit 16 is not limited to this, and may be provided above the overflow port 3 and on the same surface as the short-side bathtub wall 2a. Therefore, the bather who turned his back to the short side bathtub wall 2a side can put his head on the pillow 18 and receive water supplied from the discharge part 16 in a relaxed state on a part of the body such as the shoulder. . That is, the bather can use the discharge part 16 as a “shoulder bath”. In the jet bath system shown in FIG. 2, the discharge unit 16 and the pillow 18 are omitted for convenience of explanation.

  As shown in FIG. 3, the third piping unit 10 is branched into three on the downstream side of the branching portion between the second piping unit 9 and the third piping unit 10, and is connected to the discharge unit 16. ing. And the discharge part 16 has a fixed width | variety substantially parallel to the short side bathtub wall 2a. Therefore, the bather who turned his back to the short side bathtub wall 2a side can receive the water having a certain width discharged from the discharge portion 16 over substantially the entire shoulder. Note that the number of branches of the third piping unit 10 is not limited to three, but may be four or more, or two. Moreover, the 3rd piping part 10 does not need to be branched in the downstream.

FIG. 5 is a schematic cross-sectional view in which the vicinity of the discharge portion of this example is enlarged and viewed.
FIG. 6 is a schematic cross-sectional view in which the vicinity of the ejection unit according to a modification of the ejection unit is enlarged.
The discharge part 16 of this specific example is provided in the vicinity of the upper edge part of the bathtub 1 as mentioned above regarding FIG. A pillow 18 is provided on the discharge unit 16, and a bather who turns his back to the short side bathtub wall 2 a side shoulders the water supplied from the discharge unit 16 with his head on the pillow 18. Can be received by a part of the body. The pillow 18 is fixed to the discharge unit 16 via the pillow base 17.

  Inside the discharge part 16, there is provided a water storage part 16 a capable of temporarily storing bathtub water led to the third pipe part 10. The water storage part 16a has a certain width substantially in parallel with the short-side bathtub wall 2a so as to substantially follow the outer shape of the discharge part 16, and is formed in a flat shape. Since the water storage part 16a is a flat space larger than the diameter of the pipe line of the third pipe part 10, the momentum of the bathtub water flowing from the third pipe part 10 can be reduced. That is, only by temporarily storing the bathtub water in the reservoir 16a without adding any special mechanism or parts, the flow rate of the bathtub water can be greatly reduced, and the disturbance of the bathtub water flow can be lost. Can do. In this way, the bathtub water rectified by the water storage section 16a is gradually discharged from the discharge port 16b facing the inside of the bathtub 1 in a substantially planar shape.

  The pillow 18 may be formed of a material having elasticity, or may be formed of a material having non-elasticity that hardly deforms when placed on the head. When the pillow 18 is formed of an elastic material, the shoulder or the like can receive water supplied from the discharge unit 16 relaxed with the head placed on the pillow 18 for a longer time. .

  In addition, the pillow 18 and the pillow base 17 do not need to be provided on the discharge part 16 like the modification represented to FIG. In this case, the discharge unit 16 can be used as an ornamental discharge unit. And since the bathtub water rectified by the water storage part 16a is discharged from the discharge port 16b facing the inside of the bathtub 1 in a substantially planar shape and gently discharged, it can enhance the design of the bathroom and enhance the production effect. it can.

Next, a modification of the present embodiment will be described with reference to the drawings.
FIG. 7 is a schematic view of a jet bath system according to a modification of the present embodiment as seen from the plane direction. Moreover, FIG. 8 is the schematic diagram which looked at the jet bath system concerning this modification from the side surface direction of the short side bathtub wall.
Moreover, FIG. 9 is the schematic diagram which looked at the jet bath system concerning this modification from the side surface direction of the long side bathtub wall.

  In the jet bath system according to this modification, an air blow pump 33 that allows air bubbles to be mixed into the bath water is provided below the pump 7. The air blow pump 33 is connected to the air intake port 31 via the second air piping part 32. Since the second air piping portion 32 communicates with the atmosphere via the air intake port 31, the air blow pump 33 can suck the atmosphere via the air intake port 31 and the second air piping portion 32. it can.

  The air blow pump 33 is controlled based on a signal from the control unit 21 (see FIG. 1) in response to an operation of the operation unit 22 (see FIG. 1) by the user. Then, by driving the air blow pump 33 based on the control signal, the air sucked through the air intake port 31 and the second air piping portion 32 is air blow nozzle 35 via the third air piping portion 34. Air can be mixed into the bath water.

  The air blow nozzle 35 is provided on the bottom surface portion 2 c of the bathtub 1. Therefore, powerful air with a large amount of air bubbles or air with a small amount of air bubbles can be ejected from the bottom surface to a bather who turns his back to the short side bathtub wall 2a side. The amount of bubbles can be set by operating the operation unit 22 by the user, for example. In the case of ejecting powerful air with a large amount of bubbles, it is possible to locally stimulate a bather's lower limb, for example. On the other hand, in the case of jetting gentle air with a small amount of bubbles, the bather can experience the feeling of being gently wrapped in bubbles and can relax the mind.

  On the other hand, the drive of the air blow pump 33 can also be stopped based on the control signal by a user's operation. As a result, the supply of air from the air blow nozzle 35 to the bath water is shut off. According to this, the user can receive the jet flow ejected from the nozzle 12 intensively on the waist, back, etc., and can obtain a local massage feeling. And when the drive of the pump 7 is also stopped based on the control signal by a user's operation, the user can bathe in a more calm state. In addition, about another structure, it has a structure similar to the jet bath system represented to FIGS.

  The jet bath system according to this modification is similar to the jet bath system shown in FIGS. 2 to 4, and includes a third pipe portion 10 branched from the first pipe portion 8, and a third pipe portion 10. And a discharge section 16 connected to the downstream end. The suction port 5 is provided at a position lower than the operable water level 20 of the pump 7. Further, the pipe line of the first piping unit 8 is provided at a position higher than the operable water level 20 of the pump 7. Furthermore, the discharge unit 16 (downstream end of the third piping unit 10) is provided at a position higher than the pipe line of the first piping unit 8. Therefore, in the jet bath system according to this modification, even if the nozzle 12 is provided at a position lower than the operable water level of the pump 7, at least the first piping unit 8 and the second piping unit 9 are used. The air existing in any of the air escapes from the discharge unit 16 via the third piping unit 10. That is, an operable water level can be accumulated in the pump 7.

  Therefore, even when parts or mechanisms other than the pump 7 such as the air blow pump 33 are provided, the pump 7 can be disposed relatively freely. And as a result of having arrange | positioned on the air blow pump 33 like the modification represented to FIGS. 7-9, even if the pump 7 is arrange | positioned in the position higher than the nozzle 12, the 1st piping part 8 The air present in at least one of the second piping part 9 escapes from the discharge part 16 via the third piping part 10. Therefore, it is possible to suppress the pump 7 from idling and the performance of the blow operation from being deteriorated.

  Further, in this modification, an air pipe portion (not shown) for connecting the air intake port 41 and the nozzle 12 is provided, and air in the atmosphere is mixed into the nozzle 12 via the air intake port 41 and the air pipe portion (not shown). A bubble-containing jet may be ejected. Furthermore, an on / off valve may be provided in the middle of an air pipe section (not shown), and air on / off may be switched by controlling the on / off valve. In this way, even when other air pipes or on / off valves are further provided, the pump 7 is disposed at a position that does not interfere with the air pipes or on / off valves and is higher than the nozzle 12. can do. And the air which exists in the inside of at least any one of the 1st piping part 8 and the 2nd piping part 9 can be discharged | emitted from the discharge part 16 via a 3rd piping part.

  As described above, according to the present embodiment, the suction port 5 is provided at a position lower than the operable water level 20 of the pump 7. Further, the pipe line of the first piping unit 8 is provided at a position higher than the operable water level 20 of the pump 7. Furthermore, the discharge unit 16 (downstream end of the third piping unit 10) is provided at a position higher than the pipe line of the first piping unit 8. According to this, even when the nozzle 12 is provided at a position lower than the operable water level of the pump 7, it exists inside at least one of the first piping portion 8 and the second piping portion 9. Since air escapes from the discharge part 16 via the 3rd piping part 10, it can suppress that the pump 7 raise | generates idling. In addition, since the restriction on the arrangement position such as the necessity of arranging the pump 7 at a position lower than the nozzle 12 can be relaxed, the degree of freedom in design can be improved.
