Description

  The present invention relates to a construction method for installing a flush toilet equipped with a water storage tank on a drain pipe through a drain socket.

  When constructing flush toilets, generally, drainage pipes installed on the floor or wall and the toilet body are not directly connected, and a drainage socket is often interposed between them (for example, Patent Document 1). reference). This is because by appropriately selecting the drain socket, it is possible to absorb the positional deviation between the drain pipe portion of the toilet body and the drain pipe. In particular, when installing a new model toilet for remodeling, etc., the position of the existing drainage pipe may not match the design of the toilet. In such a case, the drain socket functions effectively.

JP 2008-82032 A

  By the way, a flush tank is generally provided with a water storage tank. If the structure which attaches a tank integrally to the back of a toilet bowl body as described in the cited reference 1 is employ | adopted, the whole toilet bowl can be comprised in a low silhouette. However, when such a configuration is adopted, there is a concern that the tank becomes obstructive during construction of the toilet and it becomes difficult to see the drain socket, causing interference between the tank and the drain socket.

  This invention is made in view of such a subject, and one of the objectives is to provide the construction method which can install a toilet bowl in a drain pipe, preventing interference with a tank and a drain socket.

  In order to solve the above-described problems, an aspect of the present invention is a flush-type large apparatus including a toilet body having a drain pipe provided in a toilet bowl and a tank for storing wash water supplied to the toilet body. A construction method in which a toilet is installed in a drain pipe through a drain socket, the first step of arranging a tank with the drain socket as a reference for positioning, and a toilet body with a drain pipe inserted into the drain socket A second step of assembling the toilet main body to the tank.

  According to this aspect, since the tank and the toilet bowl main body are individually and sequentially disposed on the basis of the drain socket, the interference between the tank and the drain socket can be prevented.

  The first step may include a step of connecting the drain socket to the drain pipe and a step of arranging the tank with reference to the drain socket connected to the drain pipe. According to this aspect, since the drain socket and the tank are individually arranged with respect to the drain pipe, the work can be easily performed even if the tank is configured to be large.

  Alternatively, the first step may include a step of assembling a tank to the drain socket to form a connection unit, and a step of installing the connection unit in the drain pipe by connecting the drain socket to the drain pipe. . This aspect is particularly effective when it is difficult to assemble the tank after the drain socket is installed in the drain pipe due to the shape of the drain socket or the tank. For example, in the case of so-called wall drainage in which a drain pipe is provided on a wall surface to be installed, it is assumed that the shape of the drain socket becomes complicated. Even in such a case, by installing the drain socket and the tank in advance, the installation to the installation target becomes easy.

  More specifically, the positioning between the drain socket and the tank may be realized by a fitting structure of both. If it does in this way, positioning will be made autonomously only by assembling a drain socket and a tank, and work efficiency can be raised.

  In addition, when the tank is disposed in the drain socket, the shape of the tank may be determined so that the connection port of the drain socket can be exposed. Thereby, the operation | work which inserts the drain pipe part of a toilet bowl main body into a drain socket becomes easy.

  In that case, the shape of the tank may be determined so as to be disposed in a manner surrounding the connection port of the drain socket. The “surrounding” referred to here may be a structure integrally connected in a ring around the connection port, or may be arranged around the connection port so as to be substantially circular, although a part of the ring is divided. With such a configuration, the capacity of the tank can be increased while effectively using the space below the toilet body.

  Furthermore, the drain pipe part is preferably provided so as to be exposed behind the toilet body. With such a configuration, the operator can stably assemble the toilet body while visually checking the positional relationship between the drain pipe portion and the drain socket.

[First Embodiment]
FIG. 1 is a perspective view of the toilet according to the first embodiment as viewed from above. FIG. 2 is a rear view of the toilet. FIG. 3 is a central longitudinal sectional view of the toilet. For convenience of explanation, each figure shows a state in which the toilet seat, toilet lid, local cleaning device, side panel and the like of the toilet bowl are removed.

  As shown in FIG. 1, a toilet 1 according to this embodiment is a flush toilet, and is configured by assembling a resin tank 4 to a ceramic toilet body 2. Behind the toilet body 2 are provided various functional parts such as a local cleaning device and a valve (not shown), a pipe 6 for connecting the toilet body 2 and the tank 4 and the like. A pump 8 for pumping up internal cleaning water is integrally provided at the upper end of the tank 4.

  As shown in FIG. 2, a drain pipe portion 9 is provided so as to protrude (expose) rearward from the toilet body 2. The drain pipe portion 9 is connected to a drain pipe of a toilet (construction target) via a drain socket 10. The tank 4 is assembled in such a manner that the front half of the tank 4 is inserted into the lower region of the toilet body 2 so as to bypass the drain socket 10, and the rear half of the tank 4 is erected along the rear part of the toilet body 2.

  As shown in FIG. 3, the toilet bowl body 2 includes a toilet bowl 12 that receives filth and a drain pipe 9 that extends from the bottom of the toilet bowl 12. The toilet bowl 12 has an outlet 14 below the sealing surface 13. A rim water passage 16 for generating a swirling flow is formed along the periphery of the upper left portion of the toilet bowl 12. On the other hand, a drop channel 18 (described later) for generating a flow for dropping the swirling flow toward the outlet 14 is formed on the upper right side of the toilet bowl 12 (see FIG. 4A). The drain pipe part 9 has a curved shape extending obliquely downward from the outlet 14 toward the rear, subsequently extending obliquely upward, and subsequently extending downward in the vertical direction. The drain pipe part 9 is connected so that the tip part is inserted into the connection port 20 opened at the upper end part of the drain socket 10. The lower end of the drain socket 10 is connected to a drain pipe 24 drawn to the floor surface 22.

  The lower half of the toilet body 2 forms an accommodation space 25 for accommodating the tank 4 and the drain socket 10. In other words, in the space surrounded by the side wall of the toilet body 2, the tank 4 is installed in such a manner that the space in the lower area and the rear area of the toilet bowl 12 and the drain pipe 9 is effectively used. The tank 4 is covered with a heat insulating material 26 along its outer shape, and condensation is prevented.

  The tank 4 has a concave portion 28 complementary to the lower surface of the drain pipe portion 9 on the upper surface, and is formed in an outer shape that can be satisfactorily stored in the lower space of the toilet body 2. The tank 4 is formed in an annular shape so as to surround the downstream end portion of the drain pipe portion 9 and the drain socket 10, and has a shape in which a rear portion is erected in a U shape along the rear wall of the toilet body 2 ( (See FIG. 2). With such a configuration, the toilet 1 can be configured in a low silhouette while ensuring a large capacity of the tank 4.

  FIG. 4 is a diagram illustrating the toilet body. (A) is a plan view, (b) is a right side view, (c) is a bottom view, and (d) is a rear view. As illustrated, the toilet body 2 has a semi-elliptical shape in plan view, and the drain pipe portion 9 protrudes (exposes) from the center portion of the flat rear wall 29 and extends downward in the vertical direction. A T-shaped pipe 6 is disposed slightly above the drain pipe 9.

  The pipe 6 is made of resin and has a water supply pipe portion 30 connected to the tank 4 and branch pipe portions 32 and 34 branched from the water supply pipe portion 30 to the left and right. Pipe connection holes 36 and 38 are provided in the left and right upper portions of the rear wall 29, and the branch pipe portion 32 is connected to the left hole 36 and communicates with the rim water passage 16. On the other hand, the branch pipe part 34 is connected to the right hole 38 and communicates with the dropping channel 18. The front end (upstream end portion) of the water supply pipe portion 30 opens downward. In addition, a connecting pipe 40 connected to an air intake part described later is connected to the branch pipe part 34. The connection pipe 40 extends to the opposite side of the hole 38, and the tip thereof opens downward.

  A recess 42 for fitting the tank 4 is formed on the bottom surface of the toilet body 2. The recess 42 has a semi-elliptical shape (U shape) in plan view and has a predetermined depth. A part of the drain pipe portion 9 is raised on the bottom surface of the recess 42, and has a shape complementary to the recess 28 of the tank 4. The recess 42 forms the accommodation space 25 described above.

  FIG. 5 is a perspective view of the tank as viewed from above. FIG. 6 is a diagram showing the appearance of the tank. (A) is a front view, (b) is a left side view, and (c) is a right side view. (D) is a rear view, (e) is a plan view, and (f) is a bottom view. FIG. 7 is a cross-sectional view showing the internal shape of the tank. (A) is AA arrow sectional drawing of Fig.6 (a), (b) is BB arrow sectional drawing of Fig.6 (a), (c) is Fig.6 (a). It is CC sectional view taken on the line. (D) is DD sectional drawing of FIG.6 (e), (f) is EE arrow sectional drawing of FIG.6 (e).

  As shown in FIG. 5, the tank 4 is configured by connecting an inflow / outflow portion 46 having a U shape in a rear view to the rear portion of a U-shaped main body 44 in a plan view. The main body 44 and the inflow / outflow portion 46 are integrally formed of a synthetic resin material, and the inside of the lower portion of the tank 4 communicates in an annular shape. Thereby, the annular hole formed in the lower part of the tank 4 functions as an insertion hole 64 through which the drain socket 10 is inserted in the vertical direction. The rear right side of the tank 4 constitutes an introduction part 47 for introducing cleaning water from above, and the rear left side constitutes a lead-out part 48 for leading washing water upward.

  In the upper part on the right side of the rear part of the tank 4, an inflow pipe 52 for introducing cleaning water, a float switch 54 for detecting the water level in the tank 4, an intake part 55 capable of taking air into the tank 4, and a tank An overflow connection part 56 for discharging water overflowing from 4 to the toilet body 2 is provided. The inflow pipe 52 is connected to a water guide pipe (not shown) communicating with a water supply source. The overflow connection portion 56 opens upward and is connected to the connection pipe 40 of the pipe 6. On the other hand, a pump 8 for sucking the internal cleaning water and an outflow pipe 58 for discharging the sucked cleaning water are provided on the upper left side of the rear portion of the tank 4. The outflow pipe 58 opens upward and is connected to the water supply pipe section 30 of the pipe 6. The rear right side and the rear left side of the tank 4 are connected by a hose 60 for venting air.

  When washing water is introduced through the inflow pipe 52, the water level of the tank 4 rises. At this time, when the water level reaches the set water level, the float switch 54 outputs a detection signal. Thereby, the on-off valve provided in the water guide pipe (not shown) is closed to stop the supply of the cleaning water. Thereby, the tank 4 can store a set amount of cleaning water. Thus, when the cleaning water flows into the tank 4 and the water level rises, air gathers above the left rear portion of the tank 4, but the air is led out to the right rear portion of the tank 4 via the hose 60 and flows into the inflow pipe. The exhaust gas is exhausted through 52. Thereby, the wash water can be stored in the tank 4 satisfactorily. The intake portion 55 draws air into the tank 4 when washing water flows out from the outflow pipe 58. Thereby, the tank 4 can flow out the stored wash water from the outflow pipe 58 satisfactorily.

  The cleaning water in the tank 4 is led out to the pipe 6 by driving the pump 8. At this time, the wash water is guided to the rim water passage 16 via the branch pipe portion 32 on the one hand. Thereby, the wash water flowing forward along the rim water passage 16 can be discharged into the toilet bowl 12. On the other hand, the wash water is dropped into the flow path 18 via the branch pipe portion 34. Thereby, the wash water flowing down along the rear surface of the toilet bowl 12 can be discharged.

  As shown in FIGS. 6A to 6C, a stepped insertion portion 62 formed in a two-step concave shape (arch shape) that is gradually widened downward is provided at the lower portion of the main body 44. It has been. By providing the insertion portion 62, the tank 4 can be easily assembled to a drain toilet socket for remodeling toilets, which will be described later, and the versatility of the tank 4 is enhanced.

  As shown in FIGS. 6D to 6F, the introduction part 47 and the lead-out part 48 are connected at the lower part. As shown in FIG. 6 (f), the lower portion of the tank 4 is provided with a front reservoir 44a, a side reservoir 44b, a rear reservoir 44c, and a side reservoir 44d that are integrally formed in an annular shape, and are annularly formed inside. Communicate. The rear storage part 44c is provided integrally with the introduction part 47 and the lead-out part 48 in the vertical direction, and communicates vertically with the inside. With such a configuration, an insertion hole 64 surrounded by the storage portions 44 a to 44 d is formed in the center of the rear half of the tank 4.

  For this reason, the tank 4 can be assembled from above the drain socket 10. At this time, the connection port 20 of the drain socket 10 is inserted into the insertion hole 64 and is exposed upward even after the tank 4 is assembled. In addition, since the dead space is reduced by making the tank 4 surround the drain socket 10, the space at the lower part and the rear part of the toilet body 2 can be utilized to the maximum, and the tank 4 can be made larger. .

  With such a configuration, as shown in FIGS. 7A to 7E, in the tank 4, the annular passage connected in the lower half and the U-shaped passage connected in the latter half are connected. In addition, a large internal space for storing cleaning water can be secured.

  In addition, as shown in FIG.7 (e), the water absorption pipe | tube 49 extended vertically is provided in the inside of the derivation | leading-out part 48. As shown in FIG. The upper end portion of the water absorption pipe 49 communicates with the outflow pipe 58 via the pump 8. On the other hand, a check valve 50 is provided at the lower end of the water absorption pipe 49. When the pump 8 is driven, the check valve 50 is opened, and the cleaning water in the tank 4 is pumped up through the water suction pipe 49.

  FIG. 8 is a view of the state in which the toilet body 2 and the tank 4 are assembled as seen from the bottom side. As shown in the drawing, both are assembled so that the main body 44 of the tank 4 fits in the recess 42 of the toilet body 2. At this time, as shown in the drawing, a slight play is provided between the outer shape of the main body 44 and the shape of the concave portion 42 so that the assembly of both is facilitated.

  FIG. 9 is a diagram illustrating the configuration of the drain socket 10. (A) is a front view, (b) is a right side view, (c) is a plan view, and (d) is a bottom view. (E) is the figure which looked at the state to which the drain socket 10 and the tank 4 were attached from the bottom face side. As shown in FIGS. 9A to 9D, the drain socket 10 has a socket body 70 that receives the downstream end of the drain pipe section 9, and an attachment section that is connected to the drain pipe 24 and fixed to the floor surface 22. 72, and an adjuster portion 74 that connects the socket body 70 and the mounting portion 72 (see FIG. 3).

  The socket body 70 is configured by assembling a cylindrical connection portion 78 to the upper end portion of a piping portion 76 made of a synthetic resin material. The connection part 78 is made of an elastic body (for example, rubber), and the connection port 20 described above is formed. A plurality of reinforcing ribs are provided on the side wall of the pipe portion 76. The socket body 70 has a shape slightly curved rearward.

  On the other hand, the attachment portion 72 is made of a synthetic resin material and opens downward and laterally. A flange portion 80 is provided at the lower end of the attachment portion 72 so that it can be stably fixed to the floor surface 22. A plurality of reinforcing ribs are provided between the side surface of the attachment portion 72 and the flange portion 80.

  The adjuster portion 74 is made of a synthetic resin cylinder and is installed in parallel to the floor surface 22. One end of the adjuster portion 74 is connected to the lower end opening of the socket body 70, and the other end is connected to be inserted through the side opening of the attachment portion 72. By cutting off the end of the adjuster portion 74 on the mounting portion 72 side, the distance between the socket body 70 and the mounting portion 72 can be adjusted as appropriate.

  A positioning fitting portion 82 is provided at the lower end of the socket body 70. The fitting part 82 is made of a plate-like body extending to the left and right, and has a shape in which the central part is curved slightly rearward. This curved shape is complementary to the lower side surface of the tank 4. That is, as shown in FIG. 9 (e), the front surface shape of the lower end portion of the inflow / outflow portion 46 in the tank 4 substantially corresponds to the shape of the fitting portion 82. For this reason, when the tank 4 is assembled to the drain socket 10, the position of the tank 4 with respect to the drain socket 10, that is, the construction position of the tank 4 is naturally determined.

  9C and 9E, the width w3 of the upper portion of the stepped insertion portion 62 in the tank 4 is made larger than the maximum width w1 of the adjuster portion 74 in the drain socket 10 (w3). > W1). Moreover, the width w4 of the lower part of the stepped insertion part 62 in the tank 4 is made larger than the maximum width w2 of the flange part 80 in the drain socket 10 (w4> w2). For this reason, even if the length of the adjuster portion 74 is changed, the adjuster portion 74 and the flange portion 80 do not interfere with the tank 4. That is, the tank 4 is highly versatile because it allows the length of the adjuster 74 in the drain socket 10 to be changed, and is particularly suitable for remodeling toilet specifications.

Next, the cleaning operation of the toilet 1 will be described.
When a cleaning switch (not shown) is operated in the toilet cleaning standby state, the pump 8 is driven by a control unit (not shown). Thereby, the washing water in the tank 4 is pumped up and discharged to the toilet bowl 12 through the pipe 6. When the set amount of washing water is discharged and the water level in the tank 4 reaches the minimum water level, the driving of the pump 8 is stopped. When the water level in the tank 4 is lowered in this way, air is sucked into the tank 4 from the intake portion 55, so that the wash water stored in the tank 4 flows out from the outflow pipe 58 well. When the driving of the pump 8 is stopped, the check valve 50 closes the communication port of the water suction pipe 49 and prevents the washing water from flowing backward to the upstream side.

  When the driving of the pump 8 is completed, an on-off valve provided in a water guide pipe (not shown) is opened, and cleaning water flows into the tank 4 through the inflow pipe 52. As a result, when the water level in the tank 4 rises, air gathers above the outlet 48, but this air is exhausted to the inflow pipe 52 side through the air vent hose 60. For this reason, the wash water can be stored in the tank 4 satisfactorily. When the water level in the tank 4 rises and reaches the set water level, the float switch 54 outputs a detection signal, and the on-off valve provided in the water conduit is closed. In this way, the inside of the tank 4 is filled with water and returned to the toilet cleaning standby state.

Next, the construction method of the toilet 1 will be described.
10 and 11 are diagrams showing a construction method of the toilet 1. FIG. 10 shows a state seen from diagonally forward, and FIG. 11 shows a state seen from diagonally backward. Each figure (a)-(c) has shown the flow of construction work. In the present embodiment, a construction method in which the position of the existing drainage pipe 24 cannot be changed at the time of toilet renovation, that is, a so-called remodeling toilet construction method will be described.

  When constructing the toilet 1, a method of sequentially assembling the tank 4 and the toilet body 2 using the drain socket 10 as a positioning reference is adopted. That is, instead of constructing the tank 4 in the state where it is assembled to the toilet body 2 as in the prior art, a method of sequentially installing the tank 4 and the toilet body 2 individually is adopted.

  First, as shown to Fig.10 (a), the drain socket 10 is assembled | attached with respect to the drain pipe 24 previously installed in the floor surface 22. FIG. At this time, the length of the adjuster portion 74 is adjusted based on the drawing position of the existing drainage pipe 24 and the structure of the toilet 1. And the drain socket 10 is installed in the floor surface 22 by fixing the attaching part 72 to the drain pipe 24.

  Subsequently, as shown in FIG. 10B, the tank 4 is assembled with the drain socket 10 as a reference. That is, the tank 4 is assembled so as to fit the fitting portion 82 as described above, and is fastened by the bolt 90. At this time, as shown in FIG. 11A, the connection portion 78 of the drain socket 10 is inserted into the insertion hole 64 of the tank 4. Thereby, the tank 4 is assembled to the drain socket 10 and installed on the floor surface 22.

  Subsequently, the toilet body 2 is assembled to the tank 4 as shown in FIG. At this time, the connection port 20 of the drain socket 10 is exposed upward, and the connection port of the overflow connection portion 56 and the connection port of the outflow pipe 58 are also open upward. On the other hand, as shown in FIG.11 (b), each front-end | tip of the drain pipe part 9, the water supply pipe part 30, and the connection pipe 40 is opening below. For this reason, if it inserts in the connection port 20 of the drain socket 10 visually observing the drain pipe part 9, the water supply pipe part 30 and the outflow pipe 58 will be connected naturally, and the connection pipe 40 and the overflow connection part 56 will be connected naturally. Will come to be. That is, by attaching the toilet body 2 so as to cover the tank 4 from above, the connection of each pipe can be made extremely efficiently.

  As described above, by assembling the toilet body 2 with the drain socket 10 as a reference, the tank 4 is assembled to the toilet body 2 and the toilet body 2 is installed on the floor surface 22. In this way, the construction of the toilet 1 is almost completed. Thereafter, installation of the toilet 1 is completed by assembling a toilet seat, a toilet lid, a local cleaning device, a side panel, and the like (not shown).

  As described above, in this embodiment, the tank 4 and the toilet body 2 are individually arranged in this order with the drain socket 10 as a reference. For this reason, it is possible to prevent interference between the tank 4 and the drain socket 10 in the preceding step. At that time, since the positioning of the drain socket 10 and the tank 4 is naturally realized by the fitting structure of both, the installation of the tank 4 is easy.

  Moreover, since it was set as the structure which installs the tank 4 previously in this way, when installing the toilet bowl main body 2 in a back | latter stage process, the drain pipe part 9 exposed to the back wall can be visually recognized easily. Since the connection port 20 of the drain socket 10 is exposed at the center of the tank 4, it can be easily inserted into the connection port 20 while viewing the drain pipe portion 9. At this time, since the tank 4 is already positioned, the toilet body 2 can be installed while avoiding interference with the tank 4. Furthermore, since the connection port of the pipe on the toilet body 2 side opens downward and the connection port of the pipe on the tank 4 side opens upward, both of them can be simply assembled to the tank 4 from above. Piping connection can be almost completed. That is, the installation work of the toilet body 2 serves as the assembly work of the toilet body 2 and the tank 4, and the work efficiency can be improved.

  Furthermore, in the present embodiment, the tank 4 is inserted into the drain socket 10, and the lower and rear spaces of the toilet body 2 are effectively used. Therefore, the toilet 1 is increased while increasing the capacity of the tank 4. The low silhouette of can be realized. Moreover, the versatility of the tank 4 is realized by providing the stepped insertion portion 62 extending forward on the lower surface of the tank 4 and allowing the shape change (length change) of the drain socket 10. ing. This means that, as long as the shape of the tank 4 and the shape of the socket main body 70 are matched, the drain pipe 24 can generally correspond to any position. That is, it is not necessary to prepare a tank according to the type of the drain socket, and it is possible to share the parts of the drain socket. As a result, cost reduction for construction can be realized.

[Second Embodiment]
The construction structure of this embodiment has the same configuration as that of the first embodiment except that the configuration of the drain socket is different. For this reason, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. FIG. 12 is a cross-sectional view illustrating the structure of the toilet according to the second embodiment and the construction structure thereof. FIG. 13 is a diagram illustrating the configuration of the drain socket. (A) is a front view, (b) is a left side view, (c) is a plan view, and (d) is a bottom view. (E) is the figure which looked at the state where the drain socket and the tank were attached from the bottom face side.

  As shown in FIG. 12, the construction structure of this embodiment is the same as that of the first embodiment in that it is a floor drainage type, but the adjuster portion is not provided in the drainage socket 210. That is, the length of the drain socket 210 is not appropriately changed according to the position of the drain pipe installed on the floor surface 22. However, even in such a configuration, the construction method in which the tank 4 and the toilet body 2 are individually installed sequentially with the drain socket 210 as a reference functions effectively.

  As shown in FIGS. 13A to 13D, the drain socket 210 has a socket body 270 that receives the downstream end of the drain pipe section 9, and an attachment section that is connected to the drain pipe 24 and is fixed to the floor surface 22. 272 (see FIG. 12).

  The socket body 270 is configured by assembling a connection portion 78 to the upper end portion of a piping portion 276 made of a synthetic resin material. On the other hand, the attachment portion 272 is made of a synthetic resin material, and includes a piping portion 278 that is smoothly connected to the piping portion 276 and a sealing portion 279 that supports the lower half of the piping portion 278 so as to cover it. The sealing part 279 is provided concentrically with the pipe part 278 and seals the hole formed in the floor surface 22 from above.

  A flange portion 280 is provided at the lower end of the sealing portion 279 so that it can be stably fixed to the floor surface 22. The flange portion 280 is integrally provided with a positioning fitting portion 282. The fitting portion 282 is made of a plate-like body extending to the left and right, and has a curved shape that is complementary to the lower side surface of the tank 4. That is, as shown in FIG. 13 (e), the front surface shape of the lower end portion of the inflow / outflow portion 46 in the tank 4 substantially corresponds to the shape of the fitting portion 282. For this reason, when the tank 4 is assembled to the drain socket 210, the position of the tank 4 with respect to the drain socket 210, that is, the construction position of the tank 4 is automatically determined.

  Also in the present embodiment, the same technique as that of the first embodiment can be adopted when constructing the toilet 1. In the present embodiment, since adjustment of the drain socket 210 is not assumed, application to the remodeling toilet specification is somewhat restricted, but the same effects as in the first embodiment can be obtained except for this point. .

[Third Embodiment]
The construction structure of this embodiment differs from the first embodiment in that it is a wall drainage type. Below, it demonstrates centering on difference with 1st Embodiment. FIG. 14: is sectional drawing showing the structure of the toilet bowl and its construction structure concerning 3rd Embodiment. FIG. 15 is a diagram illustrating a configuration of the drain socket. (A) is a rear view, (b) is a right side view, (c) is a plan view, and (d) is a bottom view. (E) is the figure which looked at the state where the drain socket and the tank were attached from the bottom face side.

  As shown in FIG. 14, since the construction structure of the present embodiment is a wall drainage type, the direction of the discharge port 312 of the drain socket 310 is perpendicular to the connection port 20. That is, as shown in FIGS. 15A to 15D, the drain socket 310 includes a socket body 370 formed as a synthetic resin bent pipe and a support portion 372 that supports the socket body 370 from below. (See FIG. 14). A connecting portion 78 is assembled to the upper end portion of the drain socket 310.

  A flange portion 380 is provided at the lower end of the support portion 372 so that it can be stably fixed to the floor surface 22. The flange portion 380 is integrally provided with a positioning fitting portion 382. The fitting portion 382 is formed of a plate-like body that extends to the left and right, and has a curved shape that is complementary to the lower side surface of the tank 4. That is, as shown in FIG. 15 (e), the front surface shape of the lower end portion of the inflow / outflow portion 46 in the tank 4 substantially corresponds to the shape of the fitting portion 382. For this reason, when the tank 4 is assembled to the drain socket 310, the position of the tank 4 with respect to the drain socket 310, that is, the construction position of the tank 4 is automatically determined.

Next, the construction method of the toilet 1 in this embodiment is demonstrated.
FIG. 16 is a diagram illustrating a construction method of the toilet 1. (A)-(c) has shown the flow of construction work. Also in this embodiment, a method of sequentially assembling the tank 4 and the toilet body 2 with the drain socket 310 as a positioning reference is adopted. However, the first embodiment differs from the first embodiment in that the drain socket 310 and the tank 4 are assembled before the drain socket 310 is connected to the drain pipe 324 on the wall surface.

  That is, as shown in FIG. 16A, first, the drain socket 310 and the tank 4 are assembled to form the connection unit 300. And the drain socket 310 is connected with the drain pipe 324 previously installed in the wall surface which is not shown in figure, and this connection unit 300 is fastened with the volt | bolt 90 with respect to a floor surface.

  Subsequently, as shown in FIG. 16 (b), the toilet body 2 is assembled to the tank 4. At this time, when the drain pipe portion 9 is inserted into the connection port 20 of the drain socket 310 while visually observing, the water supply pipe portion 30 and the outflow pipe 58 are naturally connected, and the connection pipe 40 and the overflow connection portion 56 are naturally connected. Will come to be. That is, by attaching the toilet body 2 so as to cover the tank 4 from above, the connection of each pipe can be made extremely efficiently.

  As described above, by assembling the toilet body 2 with the drain socket 310 as a reference, the tank 4 is assembled to the toilet body 2 and the toilet body 2 is installed on a wall surface (not shown). In this way, the construction of the toilet 1 is almost completed. Thereafter, installation of the toilet 1 is completed by assembling a toilet seat, a toilet lid, a local cleaning device, a side panel, and the like (not shown).

  Thus, although the construction method of this embodiment is different from the first embodiment in that it is applied to wall drainage, the tank 4 and the toilet body 2 are sequentially placed on the basis of the drain socket 310 when the toilet 1 is constructed. The point of installation is the same as that of the first embodiment. For this reason, the effect similar to 1st Embodiment can be acquired.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments, and various modifications can be made within the scope of the technical idea of the present invention. Nor.

  In the said 1st, 2nd embodiment, the construction which installs a tank after attaching a drain socket to a drain pipe in construction of a floor drainage type toilet was shown. In a modified example, after connecting the drain socket and the tank to form a connection unit, the connection unit may be connected to the drain pipe.

  In the said 3rd Embodiment, in the construction of the wall drainage type toilet, after the drain socket and the tank were assembled into a connection unit, the connection unit was connected to the drain pipe. This is because the tank cannot be assembled from above after the drain socket is connected to the drain pipe because the lower part of the tank has an annular shape. In the modification, after changing the shape of the tank so that it can be assembled even after the drain socket is connected to the drain pipe, the tank is installed after the drain socket is assembled to the drain pipe as in the first embodiment. You may do it. Alternatively, the positional relationship between the drain pipe and the drain socket may be set so that the tank can be assembled to the drain socket from below, and the tank may be installed after the drain socket is assembled to the drain pipe.

  In the said embodiment, the four-side storage part (44a-44d) connected cyclically | annularly in the lower part of the tank, and the structure surrounding a drain socket was shown. In the modified example, although the lower part of the tank has an annular shape, for example, a part of the annular part is divided, such as a part of the front storage part or a part of the rear storage part. Good. Even with such a configuration, the insertion hole in a form surrounding the drain socket is formed.

  In the above embodiment, the configuration for fixing the drain socket and the tank has been described. In the modified example, although the tank is arranged with the drain socket as a reference for positioning, a configuration may be adopted in which both are not fixed.
