  A general basic configuration of a bathtub circulation adapter includes a fixture that is piped to a heat source device such as a water heater and is attached to the side wall of the bathtub, and a partition that is attached to the fixture and arranged in the bathtub. (For example, refer to Patent Documents 1 to 4). The divider forms a hot water channel inside, and an outer surface is connected to the hot water channel and discharges hot water into the bathtub, and hot water in the bathtub flows into the hot water channel. It is comprised in the shape of a casing provided with a suction port.

  Such a partition is formed by combining, for example, two partition members, and since hot water circulates inside the partition, the interior of the partition is insoluble when used for a long period of time. Dirty due to etc. Therefore, the user may desire to disassemble the partition so that the inside can be easily cleaned.

  However, in the past, the actual situation is that a partition that can accurately meet such demand has not yet been proposed. That is, when a partition is configured by combining two partition members, it is necessary to appropriately form a hot water flow channel in the interior thereof, and therefore, the connection between the two partition members needs to be reliable and strong. There is. For this reason, conventionally, for example, means for adhering two partition members so that they are not separated from each other or connecting them using a plurality of screw bodies are often employed. However, with the former means, it is difficult to separate the two partition members. Moreover, in the latter means, when separating two partition members, it is necessary to loosen and remove a plurality of screw bodies, and the work is very complicated.

  In addition, in patent document 1, although the structure of the bathtub circulation adapter which enabled easy removal of the whole part corresponded to a partition from another part was disclosed, this structure comprises a partition It is not possible to separate the two partition members to facilitate cleaning of the inside of them. Further, Patent Document 2 discloses a means for providing concave and convex engaging means and engaging them with each other as means for attaching a cover filter to the partition. It is only necessary that the two partition members of the partition member can be engaged using the same engaging means. However, in the partition member, as described above, the two partition members are more reliably connected. It is necessary to apply the engaging means as described in Patent Document 2 as it is. In the partition, the partition wall for forming the hot water flow path is formed in the two partition members, and there is also a special feature that it is difficult to adopt a structure in which these two partition members are rotated and engaged with each other. .

And a part of the band-plate-like protrusion is separated from the first plate part, so that the engagement part of the band-plate-like protrusion and the corresponding cover are provided. It is configured as a leaf spring capable of exerting an elastic force in a predetermined direction in which the engaging portion engages, and the protruding portion in the band plate shape is arranged in a direction opposite to the predetermined direction. It is characterized in that an operation portion that can be bent and deformed is provided. In the present invention, the fact that the plurality of projecting portions can be “fitted” to the peripheral wall portion of the second partition member means that the plurality of projecting portions contact the entire circumference of the peripheral wall portion of the second partition member. It is a concept that includes a relationship in which a plurality of protruding portions are fitted so as to partially contact a part of the peripheral wall portion.

  According to such a configuration, the following effects can be obtained.

  First, the first and second partition members are connected to each other by fitting the plurality of projecting portions of the first partition member to the peripheral wall portion of the second partition member and covering the engaging portions thereof. This can be done by engaging the engaging portion. Among the plurality of protrusions, at least one protrusion is configured as a band-plate-like protrusion that functions as a leaf spring, and using the elastic force of the band-plate-like protrusion, the engagement portion It is possible to maintain the engagement state between the engagement portion and the engaged portion so that the engagement is not easily released. Therefore, the connection between the first and second partition members can be ensured.

  Secondly, in the state where the first and second partition members are connected to each other, if the operating portion is operated to bend and deform the band-plate-like protruding portion, the engaging portion of the protruding portion corresponds to this. The engaged state with the engaged portion to be released can be released. This makes it possible to easily remove the first partition member from the second partition member. Therefore, the partition can be disassembled very easily by a so-called one-touch operation, which is suitable for cleaning the inside of the partition. Of course, the work of reassembling the first partition member to the second partition member after disassembly can be easily performed.

By tightening the first and second screw portions 15a and 15b, the pair of flanges 120 and 140 sandwich the peripheral edge portion of the through hole 71 of the side wall 70 of the bathtub 7, and this pinching action causes the external pipe connected body. 1 a and the inner fastening body 1 b are fixed to the side wall 70. Between the flanges 120 and 140, seals 97a and 97b for water stop sealing are interposed. A third screw portion 15 c is formed inside the inner fastening body 1 b, and this is used for screwing and mounting the leak tester to the fixture 1.

  As shown in FIGS. 3 and 4, the rear member 2b of the partition 2 has a back plate portion 21 having a basic shape in a front view and a pair of notches 21a formed in the vicinity of the lower portion. And a tubular portion 20 having one end connected to the back plate portion 21. The back plate portion 21 corresponds to an example of a second plate portion referred to in the present invention. The back plate portion 21 has a rib shape for forming an upper peripheral wall portion 22a and a lower peripheral wall portion 22b formed on the outer periphery of the back plate portion 21 and a pair of hot water flow paths 45a and 45b described later in the partition 2. And a plurality of (for example, a total of three) arcuate long hole screw body insertion holes 24 are provided. Near the center of the back plate portion 21, a substantially semicircular opening 25 a communicating with the inside of the tubular portion 20 and a substantially arcuate opening 25 b not communicating with the inside of the tubular portion 20 are formed.

A part of the tubular portion 20 is formed as a bent portion 20a, which serves to place the openings 25a and 25b close to each other and in the vicinity of the center portion of the back plate portion 21. The upper peripheral wall portion 22a and the lower peripheral wall portion 22b are provided with a plurality of (for example, three) engagement holes 59a and 59b for attaching the front member 2a to the rear member 2b. These engagement holes 59a and 59b correspond to an example of the engaged portion in the present invention, and details thereof will be described later.

  The rear member 2b is attached to the inner fastening body 1b of the fixture 1 by inserting a plurality of screw bodies 79 as shown in FIG. A plurality of screw holes 19 are formed in the front surface portion of the internal fastening body 1b, and each screw body 79 is screwed into this portion. As will be described later, the front member 2a can be attached to and detached from the front portion of the rear member 2b. Such attachment and detachment can be performed while the rear member 2b is attached to the internal fastening body 1b. is there.

  As shown in FIGS. 5 and 6, the front member 2 a includes a front plate portion 26 having a basic shape in a front view and a pair of extending portions 26 a that project obliquely downward. The front plate portion 26 corresponds to an example of a first plate portion referred to in the present invention, and serves to cover the entire front surface portion of the back plate portion 21 of the rear member 2b. A rib-shaped partition wall 23a is formed on the back side of the front plate portion 26. The rib-shaped partition wall 23a has a shape that can overlap and abut the partition wall 23b of the rear member 2b. . When the front member 2a is assembled so as to overlap the front portion of the rear member 2b, a pair of hot water flow channels 45a and 45b are formed in the partition 2 by the partition walls 23a and 23b. 12 are a pair of hot water passages 45a and 45b formed on the front surface of the back plate portion 21 of the rear member 2b. These hot water passages 45a and 45b have hot water inside. When the water flows, it has a relatively simple shape so that stagnation is less likely to occur, and the flow path width is suppressed to a minimum width necessary for securing a desired hot water flow rate or a width close thereto. The location where the notch 21a of the rear member 2b is formed corresponds to the discharge ports 28a and 28b. When the front end surfaces of the partition walls 23a and 23b are brought into contact with each other, they may simply be abutted, but instead, for example, a convex rib is formed on one of the partition walls 23a and 23b and A concave groove may be formed and these may be fitted to each other. If it does in this way, it will become difficult to produce a clearance gap between partition wall 23a, 23b, and a sealing performance can be improved. Further, as a means for improving the sealing performance, a packing may be interposed between the front end surfaces of the partition walls 23a and 23b.

  As shown by the halftone dot pattern in FIG. 13, the upper residual region a <b> 1 and the lower residual region a <b> 2 are also formed in the partition 2 due to the small hot water channels 45 a and 45 b being formed.

The lower portion of the partition wall 23b has a pair of line portions 232 that extend obliquely downward on both sides of the lower peripheral wall portion 22b. Between these line portions 232 and both ends of the lower peripheral wall portion 22b, there is a drainage portion. A gap 44b is formed. The lower peripheral wall portion 22b has a circular arc shape protruding downward, but the upper surface 220 of the peripheral wall portion 22b is formed in a slanting shape with a downward slope. Hot water in the bathtub 7 may flow into the upper residual area a1 and the lower residual area a2, but according to the configuration as described above, when the hot water in the bathtub 7 is discharged to the outside of the bathtub, The flowing hot water can be appropriately discharged to the outside of the partition 2 through the gaps 44a and 44b for drainage. According to such a configuration, the regions a1 and a2 are not contaminated due to residual water and are hygienic. Further, it is possible to appropriately avoid the possibility that the residual water freezes and the partition 2 is damaged in winter.

  As shown in FIGS. 5 and 6, the front plate portion 26 of the front member 2a has a pair of suction ports 27a and 27b penetrating in the thickness direction of the front plate portion 26 in addition to the partition wall 23a. A strip-shaped protrusion 5A located at the upper part of the plate part 26 and a slightly narrower protrusion part 5B located at the lower part of the front plate part 26 are also provided. Each of the suction ports 27a and 27b is arranged such that a plurality of fan-shaped small holes have a substantially circular shape, and can be opened and closed by a pair of first valve bodies 41a and 41b supported at their central portions. It is. The first valve bodies 41a and 41b have a form in which a shaft portion is connected to a flexible disc portion. Second valve bodies 42 a and 42 b are also attached to the pair of extending portions 26 a of the front plate portion 26. The second valve bodies 42a and 42b have a substantially L-shaped cross section made of the same material as that of the first valve bodies 41a and 41b, and serve to substantially open and close the hot water discharge ports 28a and 28b.

  As clearly shown in FIG. 7, the band-plate-like protruding portion 5 </ b> A protrudes from the outer peripheral edge of the front plate portion 26 in the thickness direction of the front plate portion 26 and extends along the outer peripheral edge of the front plate portion 26. The plate extends in an arc shape and is integrally formed with the front plate portion 26. However, both longitudinal end portions 50 of the protruding portion 5A are separated from the front plate portion 26, and the both end portions 50 are accompanied by elastic restoring force in the direction of the arrow Na with the longitudinal intermediate portion of the protruding portion 5A as a base. The plate spring is swingable. As a means for enhancing the function as the leaf spring, a slit 52 is also formed between the front plate portion 26 and the protruding portion 5A.

  A pair of engaging convex portions 51 a and a pair of operation portions 60 are provided at both longitudinal end portions 50 of the protruding portion 5 </ b> A. The engaging convex portion 51a is a small protrusion protruding from the outer surface of the protruding portion 5A toward the radially outward direction of the front plate portion 26, and is integrally formed with the protruding portion 5A. For example, as shown in FIG. 8, the operation unit 60 is provided by welding an appropriate part 6 made of resin or the like formed separately from the front member 2a. The operation unit 60 has a substantially rectangular plate shape, and a part thereof protrudes outward in the radial direction from the outer periphery of the front plate unit 26. The front plate portion 26 is a recess for avoiding interference between the operation plate 60 and both end portions 50 of the projecting portion 5 </ b> A inward in the radial direction of the front plate portion 26. 260 is provided. The concave portion 260 also serves to separate the longitudinal end portions 50 of the protruding portion 5A from the front plate portion 26 so as to function as a leaf spring. The upper peripheral wall portion 22a of the rear member 2b has two engaging holes 59a for engaging with the engaging convex portions 51a and two concave grooves for avoiding interference with the protruding portion 61 of the component 6. 58 is formed. Although the engagement hole 59a is shown as a through hole in the drawing, it can also be formed as a non-through hole.

  Unlike the belt-like projecting portion 5A, the projecting portion 5B is not formed in a leaf spring shape, and protrudes in the thickness direction from the front plate portion 26, and the radius of the front plate portion 26 from this portion. And an engaging convex portion 51b that protrudes outward in the direction. The two projecting portions 5A and 5B are provided in an arrangement that can be partially fitted into the upper and lower peripheral wall portions 22a and 22b of the rear member 2b, and a total of three engaging convex portions 51a and 51b Around the center of the front plate portion 26, it is arranged at substantially equal intervals. The lower peripheral wall portion 22b of the rear member 2b is formed with an engagement hole 59b that can be engaged with the engagement convex portion 51b. However, since the upper surface 220 of the lower peripheral wall portion 22b is inclined as described above, a notch groove 223 for avoiding interference with the protruding portion 5B is formed on the inclined surface. (See FIGS. 3 and 4). As shown in FIGS. 9 and 10, the front member 2 a is detachably assembled to the rear member 2 b by using the two protrusions 5 </ b> A and 5 </ b> B, and thereby the partition 2 is configured. The details will be described later.

  As shown in FIGS. 1 and 2, a cover filter 3 is attached to the partition 2. The cover filter 3 has a circular cap shape, and a plurality of small holes 30 for passing hot water are formed in the front surface portion thereof, and the peripheral wall portion faces the discharge ports 28a and 28b of the partition 2. An opening 31 is formed. In FIG. 2, a horizontally long substantially oval portion represented in the front portion of the cover filter 3 is a closed surface where the small holes 30 are not provided, and from the inside of the bathtub 7 to the suction ports 27a and 27b. To prevent direct flow of hot water. The cover filter 3 is attached so as to cover the front surface and the outer periphery of the partition 2. As an attachment means, an appropriate locking convex portion (not shown) is provided on the peripheral wall portion of the cover filter 3. For example, a means for engaging the engaging projection with the engaging step 221 formed on the peripheral wall portions 22a and 22b of the rear member 2b can be used (see FIGS. 3 and 4). In the mounting structure of the cover filter 3 and the partition 2, it is not necessary to provide a water seal between them, and it is possible to mount the cover filter 3 by rotating the cover filter 3 relative to the partition 2. Therefore, it is possible to employ a relatively simple engaging means as described above as the cover filter attaching means. The cover filter 3 is formed in a structure that avoids interference with the operation unit 60 of the front member 2a.

  As shown in FIG. 1, the tubular part 20 of the partition 2 is fitted to the inner cylinder part 17 of the external pipe connector 1a. Inside the fixture 1, there are formed a hot water channel 16a including the inside of the short tube portion 13a and a region connected thereto, and a hot water channel 16b including the inside of the short tube portion 13b and a region connected thereto. The hot water flow paths 45a and 45b of the partition 2 are individually communicated with the hot water flow paths 16a and 16b.

  The bathtub circulation adapter A is configured to generate a hot water flow as described below. That is, as shown in FIG. 14 (a), in the state where the short pipe portions 13a and 13b are respectively set to the return side and the forward side, the hot water flow passages 16a and 45a have negative pressure, so the first valve body 41a opens, and the hot water in the bathtub 7 flows into the hot water flow paths 45a and 16a from the suction port 27a and is returned to the heat source device 99. On the other hand, when hot water is supplied from the heat source device 99 to the hot water flow paths 16b and 45b, the pressure in these portions rises, so that the second valve body 42b is opened, and hot water enters the bathtub 7 from the discharge port 28b. Discharged. In contrast, as shown in FIG. 5B, when the short pipe portions 13a and 13b are on the forward side and the return side, respectively, the second valve element is caused by the pressure increase in the hot water flow paths 16a and 45a. 42a opens and hot water is discharged into the bathtub 7 from the discharge port 28a. On the other hand, since the inside of the hot water flow paths 16b and 45b has a negative pressure, the first valve body 41b is opened and hot water in the bathtub 7 flows into the hot water flow paths 45b and 16b from the suction port 27b. Thus, in this bathtub circulation adapter A, hot water in the bathtub 7 can be appropriately circulated regardless of whether each of the short pipe portions 13a and 13b is set to the forward side or the return side. it can. The bathtub circulation adapter A can also be used for dropping hot water into the bathtub 7. As shown in FIG. 14 (c), when hot water is supplied to both the short pipe portions 13a and 13b, the first valve bodies 41a and 41b maintain the closed state due to their pressure. On the other hand, the second valve bodies 42a and 42b are opened by the pressure. Therefore, hot water is discharged into the bathtub 7 from each of the discharge ports 28a, 28b, and the flow rate when dropping hot water can be increased.

  Next, the operation of the bathtub circulation adapter A will be described.

  First, in the state where the front member 2a is assembled to the rear member 2b of the partition 2, as shown in FIG. 9, the two protruding portions 5A and 5B of the front member 2a are the upper and lower peripheral wall portions 22a of the rear member 2b. , 22b. Since the outer surface of the strip-shaped protruding portion 5A can be brought into contact with the inner surface of the upper peripheral wall portion 22a in a wide area, an effect of stabilizing the fitting state is also obtained. As shown in FIGS. 10A and 11, the engaging protrusions 51a and 51b of the protrusions 5A and 5B can be engaged with the engaging holes 59a and 59b of the rear member 2b. As described above, both end portions 50 of the belt-like projecting portion 5A function as leaf springs, and as shown in FIG. 10A, this projecting portion 5A is elastically biased in the direction of the arrow Nb. Using the force, it is possible to prevent the engagement state between the engagement convex portion 51a and the engagement hole 59a from being released. Further, the protruding portion 5A can be pressed against the inner side surface of the upper peripheral wall portion 22a, and the reaction state prevents the engaging convex portion 51b of the protruding portion 5B from being released from the engaging state with the engaging hole 59b. can do. For this reason, the assembly of the partition 2 is ensured.

  Next, in the assembled state of the partition 2 described above, when each operation unit 60 is pressed radially inward (opposite to the arrow Nb) of the back plate portion 26 against the elastic force of the protruding portion 5A, FIG. As shown in FIG. 10 (b), the engaging convex portion 51a is easily removed from the engaging hole 59a, and the engaged state is released. Therefore, the upper part of the front member 2a can be detached from the rear member 2b. Further, when the upper part of the front member 2a is detached from the rear member 2b in this way, the engaging convex part 51b of the protruding part 5B located at the lower part of the front member 2a can be easily removed from the engaging hole 59b. Thus, the entire front member 2a can be easily detached from the rear member 2b. Since a part of the operation part 60 protrudes outward in the radial direction from the back plate part 26 and the upper outer peripheral wall 22a in the assembled state of the partition 2, the pressing operation of the operation part 60 is also easy. For this reason, in this bathtub circulation adapter A, the operation of removing the front member 2a from the rear member 2b is easy, and the inside of the partition 2 can be easily cleaned. Further, when assembling the front member 2a after cleaning, it is only necessary to push the protruding portions 5A and 5B so as to fit the upper and lower peripheral wall portions 22a and 22b of the rear member 2b. is there.

  As described above, in this bathtub circulation adapter A, it is possible to make the assembly of the front member 2a of the partition 2 easy while removing the front member 2a. As a means for giving the projecting portion 5A an elastic biasing force, a simple means is adopted in which the projecting portion 5A is formed in a strip shape and a part of the projecting portion 5A is separated from the front plate portion 26. Therefore, the configuration is easy, and the manufacturing cost can be reduced by integrally forming the protruding portion 5A and the back plate portion 26. Further, since the protruding portion 5A is formed in such a band plate shape and is provided along the outer peripheral edge of the front plate portion 26, the operating portion 60 is attached in a partially protruding state so as to be easily operated. You can also. Each of the projecting portions 5A has both longitudinal end portions 50 function as spring plates, and the projecting portions 51a are individually provided on the both end portions 50. The projecting portions 5A include two projecting portions. It plays a role equivalent to. Therefore, the configuration is reasonable, and it is suitable for simplifying the structure of the entire partition by reducing the number of protrusions provided on the front member 2a.

  The present invention is not limited to the contents of the above-described embodiment. The specific structure of each part of the bathtub circulation adapter and the partition according to the present invention can be varied in design in various ways.

  In the above-described embodiment, of the two projecting portions 5A and 5B, only the projecting portion 5A has a strip shape that functions as a leaf spring, and the projecting portion 5B is configured not to have such a function. However, the present invention is not limited to this. In the present invention, all of the plurality of projecting portions may be configured to function as a leaf spring like the projecting portion 5A. However, such a configuration complicates the structure and increases the number of operation units. Therefore, from the viewpoint of simplification of the structure and operability, as in the above-described embodiment, a configuration in which a band plate-like protrusion having a leaf spring function and a protrusion not having such a function are combined. It is preferable to do. Further, the belt-like projecting portion does not necessarily have a configuration in which both longitudinal end portions thereof are leaf springs and have engaging convex portions, for example, only one longitudinal end portion is a leaf spring. It can also be set as the structure which is made into and has a convex part for engagement.

  In the above-described embodiment, the front member 2a is provided with the protruding portions 5A and 5B having the engaging convex portions 51a and 5b as the engaging portions, and the rear member 2b is provided with the engaging holes 59a and the engaging portions. 59b is provided, but in the present invention, it can be configured in the opposite manner. That is, the rear member may be provided with a protrusion having an engaging portion, and the front member may be provided with an engaged portion. In this case, the rear member corresponds to the first partition member referred to in the present invention, and the front member corresponds to the second partition member referred to in the present invention. The engaging part and the engaged part in the present invention may be convex or concave. The concave shape includes a hole. The plurality of projecting portions provided on the first partition member may be configured to be fitted outside the peripheral wall portion of the second partition member.

  The partition is preferably configured as a non-polar type in which the pair of hot and cold flow channels 45a and 45b can correspond to both the return side and the return side. It can also be configured as a type in which the return side is fixed (a type in which only one set of inlet and outlet for hot water is provided).

  The fixture of the bathtub circulation adapter according to the present invention can be manufactured in various configurations. For example, as the fixture, the fixture is attached to the wall of the bathtub by means different from the means for sandwiching the side wall of the bathtub from both sides. It can also be set as the structure attached. The specific means for attaching the partition to the fixture is not limited. The attachment site | part of a bathtub circulation adapter is not restricted to the side wall of a bathtub, For example, it can also be made into the bottom wall of a bathtub.
