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 jet device that gives a massage effect by causing a jet to jet into the bathtub by circulating bath water and hitting the jet against the human body surface (Patent Document 1). There is also a bathtub circulation device that circulates bathtub water and purifies and keeps the bathtub water (Patent Document 2). As in the devices described in Patent Documents 1 and 2, a device that circulates bath water generally connects a suction port that sucks in bath water, a pump that circulates bath water, and a suction port and a pump. And piping.

  In general, the pump is disposed outside the short-side bathtub wall and on the side of the bathroom in the bathroom so that an operator or the like can easily perform maintenance of the pump. Accordingly, the pipe connecting the suction port and the pump is disposed outside the short-side bathtub wall and on the back side of the pump when viewed from the washing area side.

  However, in such a pump and piping installation mode, there is a problem that the piping work becomes difficult. This is the outside of the bathtub, and is arranged on the washing room side for work in a limited space between the bathtub and a member provided around the bathtub, such as a heat insulating pan or a floor pan, or a bathroom wall. This is because the installed pump gets in the way. Another reason is that the mounting position of the pipe is difficult to see because the pump is disposed on the washing station side.

Also, the water supply pipes for water supply and hot water supplied from the outside of the bathroom, or the circulation pipes for heat insulation and heating connected to the water heater are outside the bathtub wall on the short side and on the washing room side of the bathroom In the case where the pump is disposed, the pump is disposed farther from the water supply pipe and the circulation pipe when viewed from the washing station side. In this way, when the pump is disposed on the back side when viewed from the washroom side, the piping connecting the suction port and the pump is further disposed on the back side, making it difficult to install the piping. There is a problem of becoming.

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.
Moreover, FIG. 2 is the schematic diagram which looked at the jet bath system concerning this embodiment from the plane direction.

  The jet bath system according to this embodiment mainly includes a bathtub 1 and a jet jet section for sucking the bathtub water in the bathtub 1 and ejecting the bathtub water from the nozzles 12 and 16 into the bathtub water again. Moreover, you may provide the air supply part which enables a bubble to be mixed in the jet flow ejected from the nozzles 12 and 16. FIG.

  The bathtub 1 can store bathtub water and has a suction port 5 for sucking the stored bathtub water. In the present specification, the term “water” includes not only cold water but also heated hot water. The suction port 5 is formed in the long side bathtub wall 2 c in the bathtub 1, and is connected to the suction port of the pump 9 through the upstream pipe part 6, the connection part 7, and the downstream pipe part 8. In addition, the upstream piping part 6 and the downstream piping part 8 may be directly connected without the connection part 7 being interposed. When the pump 9 is driven, the bathtub water stored in the bathtub 1 is sucked into the upstream piping section 6 from the suction port 5.

  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 9. 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. Furthermore, it is desirable to form the suction port 5 at a position that is easy to see from the washing room 51 side of the bathroom so that it can be easily confirmed when it is blocked by, for example, hair. Then, the suction inlet 5 of this embodiment is formed in the long side bathtub wall 2c of the back side seeing from the washing place 51.

  A discharge conduit 10 is connected to the discharge port of the pump 9, and two jet supply systems are connected to the discharge conduit 10 via a three-way valve 45 as a switching valve. These two jet supply systems are provided in two branches with respect to the discharge pipe section 10, 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 10 via the three-way valve 45, and a discharge pipe section 10 and a first blow pipe section discharged from the pump 9. 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 10 via the three-way valve 45, and a discharge pipe section 10 and a second blow pipe section discharged from the pump 9. 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 9 and the three-way valve 45 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 a control signal by the user's operation, the three-way valve 45 is connected to the discharge pipe section 10 connected to the discharge port of the pump 9 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 conduit unit 10 are blocked. Switch. Then, the pressurized bath water sucked from the suction port 5 and pressurized by the pump 9 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 45 is connected to the discharge pipe section 10 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 10 are switched to the “second position”. Then, the pressurized bath water sucked from the suction port 5 and pressurized by the pump 9 is guided through the second blow piping section 15 and is ejected from the second nozzle 16 into the bath water.

  That is, when the pump 9 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 9 at the same time. Only one of the systems communicates with the discharge side of the pump 9 and jets are ejected from only one of the first nozzle 12 and the second nozzle 16.

As described above, the jet bath system according to the present embodiment may include an air supply unit that enables bubbles to be mixed into the jets ejected from the nozzles 12 and 16. Then, next, an air supply part is demonstrated, referring drawings.
In the bathtub rim 3 provided around the upper edge of the inner tank of the bathtub 1, the long-side bathtub wall 2 c 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 corner.

  A first air piping portion 32 is connected to the air intake port 41, and a second air piping portion 35 is connected to the first air piping portion 32 via an open / close valve 42 that opens and closes the air flow path. ing. Furthermore, a third air piping portion 37 is connected to the second air piping portion 35 via a check valve 43. The third air piping portion 37 is branched into two on the downstream side, and is connected to each of the two second blow piping portions 15.

  The check valve 43 prevents hot water from entering the second air pipe part 35 on the upstream side from the second nozzle 16 via the third air pipe part 37. Therefore, dirt such as dirt hardly adheres and accumulates in the second air piping portion 35 upstream of the check valve 43. Note that the third air piping part 37 may be connected to each of the two second nozzles 16. In addition, as shown in FIG. 2, the on-off valve 42 and the check valve 43 may be provided as an integrated type.

  The on-off valve 42 is controlled based on a signal from the control unit 21 in response to an operation of the operation unit 22 by the user. And by opening the on-off valve 42 based on the control signal, the air intake port 41 provided in the bathtub rim 3, the first air piping portion 32, the second air piping portion 35, and the third air Air in the atmosphere can be mixed into the second blow piping section 15 or the second nozzle 16 via the piping section 37, and a bubble-containing jet can be ejected. 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 42 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 fourth air piping section 38 is further connected to the air intake port 41, and one end (downstream end) of the fourth air piping section is connected to the suction port 5. Further, the fourth air piping section 38 communicates with the atmosphere via 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 fourth air piping portion 38 are brought into the interior due to the ejector effect. Air is taken in via As a result, the capacity of the pump 9 is reduced or stopped by sucking the air. Thereby, useless driving of the pump 9 in a state where the bath water is not sucked can be avoided, and the suction force at the suction port 5 is weakened, so that a part of the body of the bather, the hair, etc. can be easily from the suction port 5. Can be released.

Next, the outer structure of the short side bathtub wall 2a to which the upstream pipe portion 6 and the downstream pipe portion 8 are connected will be described in more detail with reference to the drawings.
FIG. 3 is a schematic perspective view of the outer side of the short-side bathtub wall 2a as viewed obliquely from above.

  Around the bathtub walls 2a, 2b, and 2c on the lower side of the bathtub rim 3, a heat insulating pan 55 that can prevent the bathtub water in the bathtub 1 from being cooled is provided. At least a part of the upstream piping part 6, the connection part 7, the downstream piping part 8, and the pump 9 of the present embodiment are outside the short-side bathtub wall 2 a, and are between the bathtub 1 and the heat retaining pan 55. It is provided in the space between.

  As shown in FIG. 3, the pump 9 is provided outside the short side bathtub wall 2 a and on the back side when viewed from the bathroom washroom 51 (see FIG. 2) side. More specifically, the pump 9 is provided at the corner of the long side bathtub wall 2c in which the suction port 5 is formed and the short side bathtub wall 2a in which the first nozzle 12 is provided. .

  The upstream piping section 6 passes through the corners of the long side bathtub wall 2c in which the suction port 5 is formed and the short side bathtub wall 2a in which the first nozzle 12 is provided, and is viewed from the washing place 51 side. Thus, the end 6b extends to the front side of the pump 9. The downstream piping portion 8 extends so that the end portion 8b is positioned on the near side of the pump 9 when viewed from the washing place 51 side. The end 6 b of the upstream pipe 6 and the end 8 b of the downstream pipe 8 are connected via the connection 7 on the front side of the pump 9 when viewed from the washing station 51 side.

  The material of the connecting portion 7 is not particularly limited, but it is preferably a material having elasticity such as rubber, for example, in consideration of pipe mounting workability and flexibility with respect to the position error of the pipe. On the other hand, the upstream piping part 6 and the downstream piping part 8 do not need to have elasticity like the connection part 7.

  When the jet bath system according to the present embodiment is installed in a bathroom, the heat retaining pan 55 is first installed. As will be described in detail later, the pump 9 is appropriately fixed to the heat retaining pan 55 in advance. The downstream piping 8 is connected to the pump 9 in advance, and the connecting portion 7 is connected in advance to the end 8 b of the downstream piping 8 on the opposite side of the connection with the pump 9.

  Thereafter, the bathtub 1 is installed inside the heat retaining pan 55. A suction port 5 is formed in the bathtub 1 in advance, and an upstream pipe portion 6 is connected to the suction port 5 in advance. And after installing the bathtub 1 in the inside of the heat insulation bread | pan 55, it puts a hand from the washroom 51 side in the space between the bathtub 1 and the heat insulation bread | pan 55 outside the short side bathtub wall 2a, and upstream. The pipe part 6 and the connection part 7 are connected. Note that, as described above with reference to FIGS. 1 and 2, the upstream piping unit 6 and the downstream piping unit 8 may be directly connected without using the connection unit 7.

  Here, in the apparatus provided with pumps, such as a bathtub ejection apparatus and the circulation apparatus for bathtubs, it is the outer side of the short side bathtub wall 2a and the bathroom washroom 51 side so that an operator etc. can perform maintenance of a pump easily. In some cases, a pump 9 is provided. However, when the pump 9 is provided on the washing place 51 side, the upstream piping part 6, the connection part 7, and the downstream piping part 8 are outside the short side bathtub wall 2a and viewed from the washing place 51 side. In some cases, it is disposed on the back side of the pump 9. Therefore, the pump 9 may become an obstacle in the connection work between the upstream piping section 6 and the connection section 7.

  On the other hand, according to the jet bath system according to the present embodiment, the pump 9 is provided outside the short side bathtub wall 2a and on the back side when viewed from the washing room 51 side of the bathroom. In the connection work between the pipe part 6 and the connection part 7, there is little possibility that the pump 9 becomes an obstacle. Further, the end 6b of the upstream pipe section 6 and the end section 8b of the downstream pipe section 8 are connected via the connection section 7 on the near side of the pump 9 when viewed from the washing station 51 side. There is no risk of obscuring the view of the connection. Therefore, even in a limited space between the bathtub 1 and the heat retaining pan 55, the upstream pipe portion 6 and the downstream pipe portion 8 can be easily connected via the connection portion 7.

  On the other hand, the connecting portion 7 is detachably connected to at least one of the upstream piping portion 6 and the downstream piping portion 8. Therefore, by removing the connecting portion 7 from at least one of the upstream piping portion 6 and the downstream piping portion 8, maintenance of the pump 9 and maintenance of the upstream piping portion 6, the connecting portion 7, and the downstream piping portion 8 are easily performed. be able to.

  In addition, on the side of the wash basin 51 outside the short-side bathtub wall 2a, there are water supply pipes for water supply and hot water supplied from the outside of the bathroom, or circulation pipes for heat insulation and heating connected to the water heater. It may be arranged. Even in this case, according to the jet bath system according to the present embodiment, the pump 9 is provided outside the short-side bathtub wall 2a and on the back side when viewed from the washing room 51 side of the bathroom. Therefore, interference between the pump 9 and the water supply pipe or the circulation pipe can be avoided. Thereby, the freedom degree of the arrangement position of the pump 9 can be raised.

  In addition, when the pump 9 is provided on the back side when viewed from the washing field 51 side, the end 6b of the upstream piping part 6 and the end part 8b of the downstream piping part 8 are viewed before the pump 9 when viewed from the washing field 51 side. When the suction port 5 and the pump 9 are connected without extending to the side, the connection work between the upstream pipe portion 6 and the connection portion 7 may be difficult. This is because the upstream piping portion 6 and the connecting portion 7 are disposed on the back side when viewed from the washing place 51 side, and thus it is difficult for the operator's hand to reach.

  In contrast, according to the jet bath system according to the present embodiment, the end portion 6b of the upstream piping portion 6 and the end portion 8b of the downstream piping portion 8 are viewed from the washing place 51 side to the front side of the pump 9. It is extended. The end 6 b of the upstream pipe 6 and the end 8 b of the downstream pipe 8 are connected via the connection 7 on the front side of the pump 9 when viewed from the washing station 51 side. Therefore, even when the pump 9 is provided on the back side as viewed from the washing place 51 side, the upstream pipe part 6 and the downstream pipe part 8 can be easily connected via the connection part 7. As a result, the degree of freedom of the arrangement position of the pump 9 can be increased.

FIG. 4 is a schematic cross-sectional view of the upstream piping portion, the connection portion, and the downstream piping portion as viewed from above.
Moreover, FIG. 5 is the side surface schematic diagram which looked at the upstream piping part, the connection part, and the downstream piping part from the washing-room side.
Note that the lower side in FIG. 4 corresponds to the washing area 51 side shown in FIG.

  As described above with reference to FIG. 3, the upstream pipe section 6 has the corners of the long side bathtub wall 2 c in which the suction port 5 is formed and the short side bathtub wall 2 a in which the first nozzle 12 is provided. It passes through and extends so that the end 6b is positioned on the near side of the pump 9 as viewed from the washing area 51 side. Moreover, the downstream piping part 8 is extended so that the edge part 8b may be located in the near side rather than the pump 9 seeing from the washing place 51 side. The end 6 b of the upstream pipe 6 and the end 8 b of the downstream pipe 8 are connected via the connection 7 on the front side of the pump 9 when viewed from the washing station 51 side.

  The upstream piping portion 6 and the connecting portion 7 are configured such that the upstream piping portion 6 is moved substantially parallel to the short side bathtub wall 2a as indicated by the arrow A, and the connecting portion 7 is indicated by the short side as indicated by the arrow B. It connects by moving to the bathtub wall 2a substantially in parallel. At this time, as shown in FIG. 4, a flange portion 6 a is provided in the vicinity of the end portion 6 b of the upstream piping portion 6 on the side connected to the connection portion 7. Therefore, the operator can easily connect the upstream piping portion 6 and the connecting portion 7 by grasping the collar portion 6a and pulling the upstream piping portion 6 toward the front as viewed from the washing place 51 side.

  In addition, when moving and connecting two piping to the direction which is substantially orthogonal to the short side bathtub wall 2a mutually, compared with the case where it moves and connects to the short side bathtub wall 2a substantially in parallel, It is necessary to bend and connect the wrist and arm. Therefore, when moving and connecting in the direction substantially orthogonal to the short-side bathtub wall 2a, the operator may be harder to apply force than when moving and connecting in parallel to the short-side bathtub wall 2a. There is. Therefore, as shown in FIG. 4, it is more preferable that the upstream piping part 6 and the connection part 7 are connected by moving each other to the short side bathtub wall 2a substantially in parallel.

  As shown in FIG. 5, the upstream pipe portion 6 and the connection portion 7 are fixed by a fixing member 61. The fixing member 61 is made of, for example, resin and includes a first fixing portion 61a and a second fixing portion 61b. The first fixing portion 61a is provided with fixing teeth 61c, and the second fixing portion 61b is provided with fixing teeth 61d. The operator moves the first fixing portion 61a to the center side of the fixing member 61 as shown by the arrow C, and moves the second fixing portion 61b to the center side of the fixing member 61 as shown by the arrow D. By doing so, the upstream piping part 6 and the connection part 7 can be fastened and fixed. Note that the connection portion 7 and the downstream pipe portion 8 are also fixed by the fixing member 61.

  The fixing member 61 is not limited to resin, and may be formed of metal, for example. The fixing member 61 may be a metal “retaining ring” called a “C ring” or the like. Also by this, the upstream piping part 6 and the connection part 7 can be fastened and fixed. However, in consideration of work in a limited space between the bathtub 1 and the heat retaining pan 55, it is more preferable that the fixing member be made of a resin that does not require more force when attached.

  In addition, although the upstream piping part 6 and the downstream piping part 8 shown in FIG. 4 are formed from one member, it is not necessarily limited to this. That is, the upstream pipe section 6 has a plurality of members, a member substantially parallel to the long side bathtub wall 2c in which the suction port 5 is formed, and a short side bathtub wall 2a in which the first nozzle 12 is provided. You may have the substantially parallel member and the member which connected the two members in the corner | angular part, and made the substantially right-angled shape. The downstream pipe portion 8 has a plurality of members, and includes a member substantially parallel to the long side bathtub wall 2c in which the suction port 5 is formed, and a member having a substantially right-angle shape connected to the connection portion 7. You may do it.

Drawing 6 is a mimetic diagram which looked at the jet bath system concerning this embodiment from the outside of short side bathtub wall 2a.
As described above with reference to FIGS. 1 and 2, the discharge conduit 10 is connected to the discharge port of the pump 9, and the three-way valve 45 serving as a switching valve is connected to the discharge conduit 10. The three-way valve 45 has a valve part 45a and a motor part 45b. And the motor part 45b is arrange | positioned in the back | inner side rather than the valve part 45a seeing from the washing place 51 side, as represented to FIG.

  Thereby, in the connection operation | work of the upstream piping part 6 and the connection part 7, there is little possibility that the pump 9 becomes obstructive. Further, the field of view of the connection portion between the upstream pipe portion 6 and the connection portion 7 is not blocked by the motor portion 45b. Therefore, even in a limited space between the bathtub 1 and the heat retaining pan 55, the upstream pipe portion 6 and the downstream pipe portion 8 can be easily connected via the connection portion 7.

FIG. 7 is a schematic view of the jet bath system according to the present embodiment viewed from the outside of the long side bathtub wall 2d.
FIG. 8 is a schematic cross-sectional view of the fixed portion of the pump viewed from an enlarged scale.

  As described above with reference to FIGS. 1 and 2, the pump 9 is fixed to the heat retaining pan 55 in advance. The pump 9 has fixed leg portions 9a and 9b made of plate-like metal. One end of the fixed leg portions 9a and 9b is appropriately fixed to the lower part of the pump 9, and the other end is formed in a bowl shape as shown in FIG.

  The other ends of the fixed leg portions 9 a and 9 b formed in a bowl shape are appropriately fixed to the heat retaining pan 55. The fixing method may be, for example, adhesion, or may be screwed with a screw or the like. A downstream pipe portion 8 is connected in advance to the pump 9, and a connection portion 7 is connected in advance to an end portion 8 b of the downstream pipe portion 8 on the side opposite to the connection portion with the pump 9. On the other hand, as described above, the suction port 5 is formed in the bathtub 1 in advance, and the upstream piping part 6 is connected to the suction port 5 in advance. Therefore, the suction port 5 and the pump 9 can be connected via piping by connecting the upstream piping portion 6 and the downstream piping portion 8 via the connection portion 7.

  As described above, according to the present embodiment, the pump 9 is provided on the outer side of the short-side bathtub wall 2a and on the back side when viewed from the washing room 51 side of the bathroom.
