  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the second and subsequent embodiments, the same reference numerals are assigned to configurations common to the first embodiment, and the corresponding configurations are denoted by the same regularity, and the description thereof is omitted as appropriate. In the following description, the front / rear / left / right direction means the front / rear / left / right direction viewed from the user sitting on the toilet seat.

[First Embodiment]
FIG. 1 is a partial cross-sectional side view of a toilet device 1 according to a first embodiment of the present invention. As shown in FIG. 1, the toilet device 1 according to the present embodiment is installed on a floor FL in the vicinity of a rear wall WA in the toilet room R. The toilet device 1 is a simple flush toilet device including a toilet 100, a drainage mechanism 110, and a cleaning device 120.

First, the toilet 100 will be described.
As shown in FIG. 1, the toilet 100 includes a toilet body 101 and a toilet bowl 102. This toilet 100 is formed by sanitary ware, for example.

The toilet body 101 includes a front peripheral wall portion 101a and a rear peripheral wall portion 101b.
The front peripheral wall 101a is curved inward as it goes downward from the upper surface periphery on the front side. The lower end of the front peripheral wall portion 101a is in contact with the floor FL. A toilet bowl 102, which will be described later, is disposed inside the front peripheral wall portion 101a.
The rear peripheral wall portion 101b is curved inward after extending substantially vertically downward from the upper surface periphery on the rear side. The lower end of the rear peripheral wall portion 101b is in contact with the floor FL. A drain socket 210, a flapper valve mechanism 220, and the like, which will be described later, are disposed inside the rear peripheral wall portion 101b.

The toilet bowl 102 is arrange | positioned inside the front surrounding wall part 101a as mentioned above. The toilet bowl 102 includes a front inclined portion 102a, a rear inclined portion 102b, a right inclined portion and a left inclined portion (not shown), a rim water passage 102c, and a drain port portion 102d.
The front inclined portion 102a, the rear inclined portion 102b, the right inclined portion, and the left inclined portion are inclined downward toward the center side. Adjacent inclined portions are connected in a gently curved shape.

  The rim water passage 102 c is formed on the upper peripheral edge of the toilet bowl 102. More specifically, the rim water passage 102c is formed by being sandwiched between a rim 105 that extends inward from the upper edge of the toilet bowl 102 and hangs downward, and an upper end portion of each inclined portion. The cleaning water discharged from a cleaning water supply pipe 123 of the cleaning device 120 described later flows through the rim water passage 102c. When the cleaning water flows through the rim water passage 102c, the rim 105 prevents the cleaning water from splashing outside.

  The drain port portion 102d is formed at the bottom of the toilet bowl 102 so as to open in a substantially circular shape vertically downward. A drain socket 210 of the drain mechanism 110 described later is connected to the drain port portion 102d. More specifically, the drain socket 210 is connected to the drain port portion 102d by attaching the upper surface portion 211 of the drain socket 210, which will be described later, to the flange portion 102e formed over the entire circumference of the drain port portion 102d. The The filth and the stored water W (sewage) after use are discharged from the drain port portion 102d together with the cleaning water supplied from the cleaning device 120 described later.

  As shown in FIG. 1, a toilet seat 130 and a toilet lid 140 are attached to the toilet 100. The toilet seat 130 and the toilet lid 140 are pivotally supported on the rear upper surface of the toilet body 101 via a pivotal support 150. As a result, the toilet seat 130 and the toilet lid 140 can independently take a lying state lying on the toilet body 101 and a standing state standing in a substantially vertical direction with respect to the toilet body 101.

Next, the drainage mechanism 110 will be described.
The drainage mechanism 110 includes a drainage socket 210, a flapper valve mechanism 220, and a drainage pipe 230.

  Here, FIG. 2 is a perspective view showing a state in which the flapper valve mechanism 220 of the drainage mechanism 110 is closed. FIG. 3 is a perspective view showing a state in which the flapper valve mechanism 220 of the drainage mechanism 110 is opened. 4 is a cross-sectional view taken along line AA in FIG. 2, and FIG. 5 is a cross-sectional view taken along line BB in FIG. 2 to 5, the drain pipe 230 is omitted. Hereinafter, each structure of the drainage mechanism 110 will be described with reference to FIGS.

  The drain socket 210 is connected to the drain outlet 102d of the toilet bowl 102 and constitutes a part of the drain channel. The drain socket 210 includes an upper surface portion 211, a bottom surface portion 212, and a side wall portion 213. Further, the drain socket 210 includes an inlet portion 214, an outlet portion 215, and an inclined portion 216.

The upper surface portion 211 is formed in a substantially horizontal plane shape. The upper surface portion 211 includes an inflow port portion 214 at substantially the center thereof.
The inflow port portion 214 is formed in the upper surface portion 211 so as to open upward in a substantially circular shape. A packing 214 a is provided on the inner peripheral edge of the inflow port portion 214. By fitting the drain port portion 102d with the inflow port portion 214, the drain socket 210 is connected to the drain port portion 102d. As a result, the filth and the stored water W (sewage) after use flow into the drain socket 210 from the inflow port 214 together with the cleaning water supplied from the cleaning device 120 described later.

The bottom surface portion 212 is formed in a substantially flat shape and includes a gentle slope portion 212a that gently slopes toward the rear. The bottom surface portion 212 includes an inclined portion 216 on the front side thereof.
The inclined portion 216 has an upper end connected to a front wall portion 213a facing an outlet portion 215 described later, and is inclined downward from the front wall portion 213a toward the drainage pipe 230 side. The inclination angle of the inclined portion 216 is set larger than the inclination angle of the gentle inclined portion 212a. As shown in FIG. 5, the inclined portion 216 acts as a restricting portion that restricts the rotation of the flapper valve 221. This will be described in detail later.

The side wall part 213 is comprised from the front wall part 213a, the right wall part 213b, the left wall part 213c, and the rear wall part 213d. That is, the front wall portion 213a constitutes the front portion of the drain socket 210, the right wall portion 213b constitutes the right portion of the drain socket 210, the left wall portion 213c constitutes the left portion of the drain socket 210, and the rear The wall portion 213d constitutes a rear portion of the drain socket 210.
Here, as described above, the front / rear / left / right direction in the present specification means the front / rear / left / right direction as viewed from the user sitting on the toilet seat 130, and therefore, the side on which the user sits (toilet seat 130 side) is the front. The side on which the device 120 is disposed is the rear side.

  The front wall portion 213a is formed to extend in the vertical direction with a predetermined width. A groove portion 213e that is recessed inward and extends in the up-down direction is formed on the outer side of the center of the front wall portion 213a in the width direction (horizontal direction). In addition, an extended portion 213f extending outward is provided on the lower outer side of the front wall portion 213a.

  The right wall portion 213b and the left wall portion 213c are substantially planar and are formed to extend in the vertical direction with a predetermined width. The lower portions on the front side of the right wall portion 213b and the left wall portion 213c are inclined corresponding to the inclined portion 216 of the bottom surface portion 212.

  The rear wall portion 213d includes an outflow port portion 215. The outflow port portion 215 is formed by projecting most of the rear wall portion 213d except a part such as the upper end of the rear wall portion 213d into a cylindrical shape having a substantially circular cross section toward the rear. The cylindrical outlet portion 215 is gently inclined downward toward the rear, and is connected to a drain pipe 230 described later.

  The flapper valve mechanism 220 includes a flapper valve 221, a flapper valve rotating shaft 222, a first link member 223, a second link member 224, a first magnetic member 225, a second magnetic member 226, and a rotating member. 227 and a wire 228.

The flapper valve 221 is disposed immediately below the drain port portion 102d of the toilet bowl 102, and opens and closes the drain port portion 102d. The flapper valve 221 includes a receiving portion 221a and a support portion 221b.
The receiving part 221a is formed in a rectangular dish shape. The receiving part 221a contacts the opening edge of the drain port part 102d, thereby closing the drain port part 102d.
The support portion 221b protrudes downward from the center of the lower surface of the receiving portion 221a and is formed to extend in the left-right direction. The support portion 221b has a semicircular cross section, and is pivotally supported at the distal end portion of a first link member 223 described later.

  The flapper valve rotation shaft 222 rotates the flapper valve 221 via a first link member 223 described later. The flapper valve rotation shaft 222 is provided in the upper portion of the front wall portion 213a facing the outlet portion 215 so as to extend in the width direction (left-right direction). Accordingly, the flapper valve rotation shaft 222 rotates the flapper valve 221 in a substantially vertical direction. Further, the flapper valve rotation shaft 222 is substantially orthogonal to the extending direction of the drain pipe 230 and extends in a substantially horizontal direction. As a result, the flapper valve 221 opens toward the outlet port 215 and the drain pipe 230 described later. That is, when the flapper valve 221 is opened, the receiving part 221a of the flapper valve 221 is disposed at a position facing the outlet part 215.

As shown in FIG. 2, the first link member 223 includes a pair of long prismatic link members 223a and 223a. One end side of these link members 223a and 223a is connected and fixed substantially orthogonally to the flapper valve rotating shaft 222. The other end sides of the link members 223a and 223a are rotatably connected to both ends of the support portion 221b of the flapper valve 221.
Here, the rotation of the flapper valve 221 is restricted by the first link member 223 coming into contact with the inclined portion 216 of the bottom surface portion 212. Specifically, the rotation of the flapper valve 221 is restricted by the lower surface of the first link member 223 coming into contact with the inclined surface of the inclined portion 216. In the present embodiment, for example, by setting the inclination angle of the inclined portion 216 to about 45 °, the opening degree of the flapper valve 221 is regulated within a range of about 45 °. At this time, as shown in FIG. 5, the receiving portion 221 a of the flapper valve 221 exhibits a function of guiding sewage to the drainage pipe 230.

The second link member 224 is configured by a single long columnar link member. One end side of the second link member 224 is connected and fixed substantially orthogonal to the substantially central portion of the flapper valve rotation shaft 222. The other end side of the 2nd link member 224 is connected with the 1st magnetic member 225 mentioned later so that rotation is possible.
Here, the flapper valve rotation shaft 222 passes through the groove portion 213e of the front wall portion 213a, and the second link member 224 is connected to the flapper valve rotation shaft 222 exposed in the groove portion 213e. Thereby, the 2nd link member 224 can be rotated along the groove part 213e.

The first magnetic member 225 includes a hollow cylindrical case 225a having a large diameter portion on the lower side and a small diameter portion on the upper side, and a columnar first magnet 225b housed in the large diameter portion of the case 225a. The An upper end portion of the case 225a is rotatably connected to the other end side of the second link member 224. Further, the first magnet 225b is attracted to the second magnet 226b described later with different polarities.
The first magnetic member 225 is placed on the extended portion 213f of the front wall portion 213a when the flapper valve 221 is closed. Further, when the flapper valve is opened, it is separated from the extension portion 213f.

  The 2nd magnetic member 226 is accommodated in the accommodation space provided in the extension part 213f of the front wall part 213a. The second magnetic member 226 includes a columnar support member 226a fixed in the extending portion 213f, and a columnar second magnet 226b supported by the support member 226a. As described above, the second magnet 226b attracts the first magnet 225b with different polarities.

Therefore, when the flapper valve 221 is closed, the first magnetic member 225 is placed on the extending portion 213f, so that a magnetic attraction force acts between the second magnetic member 226 and the magnetic attraction force. The flapper valve 221 is urged in the closing direction.
In addition, when the flapper valve 221 is open, the first magnetic member 225 is separated from the extended portion 213f, so that the magnetic attractive force acting between the second magnetic member 226 is released.

The rotating member 227 is configured by a flat plate member having a predetermined thickness. The rotating member 227 is fixed by connecting the left end portion of the flapper valve rotating shaft 222 to the substantially central portion thereof. That is, the rotation member 227 rotates together with the flapper valve rotation shaft 222.
Here, an insertion hole (not shown) is formed in the upper part on the front side of the left wall portion 213c, and the flapper valve rotation shaft 222 is rotatably inserted into the insertion hole. The rotation member 227 is connected to the left end portion of the inserted flapper valve rotation shaft 222.
Further, a wire 228 described later is connected to the front side surface of the rotating member 227.

  The wire 228 connects a cleaning operation lever 125 of the cleaning device 120 described later and the rotating member 227. The wire 228 is guided by guide portions 213g and 213h provided on the outer side of the upper portion of the left wall portion 213c.

  Returning to FIG. 1, the drain pipe 230 is connected to the outlet part 215 of the rear wall part 213d. That is, the drainage pipe 230 of the present embodiment is directly connected to the side wall portion 213 of the drainage socket 210, and extends inclined downward toward the wall WA of the toilet room R behind the toilet device 1. The drainage pipe 230 is connected to a transfer pipe 250 connected to a not-shown stool type stool provided in the basement or the like as wall drainage that passes through the wall WA and passes through the wall IW. Therefore, in this embodiment, it is not necessary to store the drain pipe 230 in the underfloor UF as in the prior art.

  Further, the drainage mechanism 110 further includes an angle conversion joint 240 that connects the drainage pipe 230 and the transport pipe 250. The angle conversion joint 240 is connected to the downstream side of the drain pipe 230 and connects the transport pipe 250 and the drain pipe 230 extending in a direction different from the direction in which the drain pipe 230 extends.

Next, the cleaning device 120 will be described.
The cleaning device 120 includes a cleaning tank 121, a cleaning water supply valve 122, a cleaning water supply pipe 123, a cleaning wire 124, and a cleaning operation lever 125.

  The cleaning tank 121 is installed on the upper rear surface of the toilet body 101. The cleaning tank 121 cleans the toilet bowl 102 and stores cleaning water for discharging filth after stool. A water supply pipe (not shown) is connected to the cleaning tank 121.

  The cleaning water supply valve 122 is disposed on the lower surface in the cleaning tank 121. The cleaning water supply valve 122 opens and closes a supply port formed on the lower surface in the cleaning tank 121.

  The washing water supply pipe 123 is provided so as to communicate the supply port opened and closed by the washing water supply valve 122 and the rim water passage 102 c in the toilet bowl 102. The cleaning water supply pipe 123 discharges the cleaning water in the cleaning tank 121 toward the rim water passage 102c.

  The cleaning wire 124 connects the cleaning water supply valve 122 and a cleaning operation lever 125 described later. Accordingly, the cleaning water supply valve 122 opens and closes in conjunction with the rotation of the cleaning operation lever 125.

  The cleaning operation lever 125 is disposed on the side surface of the cleaning tank 121. The cleaning operation lever 125 can be rotated in the front-rear direction of the toilet 100. The cleaning operation lever 125 is connected to the cleaning water supply valve 122 by the cleaning wire 124 as described above. Accordingly, when the cleaning operation lever 125 is rotated to one side, the cleaning wire 124 is pulled upward and the cleaning water supply valve 122 is opened, so that the cleaning water in the cleaning tank 121 passes through the cleaning water supply pipe 123. It is supplied to the rim water passage 102 c in the toilet bowl 102. For example, the cleaning device 120 of the present embodiment supplies a very small amount of cleaning water of about 500 cc or less (according to JIS) for one cleaning.

The toilet device 1 having the above configuration operates as follows.
First, when the user rotates the cleaning operation lever 125 after the stool is finished or the toilet bowl 102 is cleaned, the wire 228 is pulled toward the cleaning device 120 in conjunction with the rotation. Then, the rotating member 227 and the flapper valve rotating shaft 222 rotate together in the direction in which the flapper valve 221 is opened. At this time, since the first magnetic member 225 moves upward and is separated from the extension portion 213f, the first magnetic member 225 is released from the magnetic attractive force acting between the first magnetic member 225 and the second magnetic member 226. In addition to the waste in the toilet bowl 102 and the stored water W, the flapper valve 221 rotates in the opening direction by the weight of the cleaning water supplied from the cleaning device 120, and the waste in the toilet bowl 102 is discharged from the drain outlet 102d. The

At this time, the opening degree of the flapper valve 221 is regulated within a range of about 45 ° by the first link member 223 coming into contact with the inclined portion 216. Thereby, the sewage is efficiently guided to the drainage pipe 230 side by the receiving portion 221a of the flapper valve 221.
The sewage guided to the drainage pipe 230 circulates in the drainage pipe 230 inclined downward, and is guided to the toilet tank via the transport pipe 250.

  Next, when the user returns the cleaning operation lever 125 to the original position, the wire 228 returns to the original position. Then, the rotating member 227 and the flapper valve rotating shaft 222 rotate together in the direction in which the flapper valve 221 is closed. At this time, since the first magnetic member 225 moves downward and is placed on the extending portion 213f, the flapper valve 221 is closed by the magnetic attractive force acting between the first magnetic member 226 and the second magnetic member 226. Biased in the direction.

According to the toilet device 1 of the present embodiment having the above configuration, the following effects are exhibited.
(1) In this embodiment, the inflow port portion 214 connected to the drain port portion 102d of the toilet bowl 102 is provided on the upper surface portion 211 of the drain socket 210, and the outflow port portion 215 connected to the drain pipe 230 is provided as the drain socket. 210 is provided on the side wall portion 213, specifically on the rear wall portion 213d.
Thereby, it is possible to directly connect the drainage pipe 230 that is inclined downward toward the drainage socket 210 toward the downstream side. Therefore, the drainage pipe 230 can be extended toward the wall WA of the toilet room R without being stored in the underfloor UF, and wall drainage can be obtained. Therefore, according to the present embodiment, the underfloor UF height can be suppressed while ensuring good drainage performance.

(2) In the present embodiment, the drain pipe 230 connected to the outlet 215 provided on the rear wall 213d of the drain socket 210 is moved downward toward the wall WA of the toilet room R where the toilet device 1 is installed. It was provided so as to extend inclined.
Accordingly, the drainage pipe 230 can be reliably passed through the IW in the wall without storing the drainage pipe 230 in the underfloor UF, and thus the above-described effect is reliably achieved.

(3) In this embodiment, the flapper valve rotation shaft 222 is provided on the front wall portion 213a side facing the rear wall portion 213d of the drain socket 210 provided with the outflow port portion 215. Further, the flapper valve rotation shaft 222 is provided so as to extend in a direction substantially orthogonal to the direction in which the drain pipe 230 extends.
For example, when the flapper valve rotation shaft 222 is provided on the rear wall portion 213d side of the drain socket 210 provided with the outlet portion 215, the flapper valve 221 itself inhibits the flow of sewage to the drain pipe 230. There is a fear. On the other hand, according to this embodiment, when the flapper valve 221 is opened, the flow of sewage to the drainpipe 230 is not hindered, so that energy loss when sewage moves to the drainpipe 230 can be suppressed. Further, since the flapper valve 221 guides the sewage toward the drainage pipe 230, the sewage can be flowed more efficiently into the drainage pipe 230, and better drainage performance can be ensured with a small amount of drainage.

(4) Further, in the present embodiment, as the restricting portion that restricts the opening degree of the flapper valve 221 within a predetermined range, the inclined portion 216 that is inclined downward from the front wall portion 213a toward the drain pipe 230 is provided as the drain socket 210. Provided on the bottom surface portion 212.
For example, when the flapper valve 221 is opened by 90 ° or more, the sewage flows down vertically, and in some cases, filth adheres to the bottom surface part 212 of the drain socket 210, so that good drainage performance may not be obtained. There is. On the other hand, according to this embodiment, since the opening degree of the flapper valve 221 is regulated within 45 °, for example, the drainage performance can be further improved.

  (5) Moreover, in this embodiment, the angle conversion coupling 240 which connects the drain pipe 230 and the conveyance pipe 250 which are mutually different directions was provided in the downstream of the drain pipe 230. Thus, for example, by using an angle conversion joint for connecting a conventional vertical drain pipe and an inclined drain pipe as it is, the drain pipe 230 and the transport pipe 250 can be easily connected, and workability is improved.

Note that the present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
In the said embodiment, although the inclination part 216 was provided in the front side of the bottom face part 212 as a control part, it is not limited to this. For example, a restricting portion made of a member different from the bottom surface portion 212 may be provided, or a restricting portion made of a protrusion formed on the bottom surface portion 212 or the side wall portion 213 may be provided.

[Second Embodiment]
FIG. 6 is a partial cross-sectional side view schematically showing a toilet apparatus 1A according to the second embodiment of the present invention.
In the toilet apparatus 1A according to the present embodiment, the flapper valve mechanism 220A is not a forced discharge type but a balance type using a weight, and the flapper valve rotation shaft 222A is not the front wall part 213Aa side but the rear wall part 213Ad side. Is different from the first embodiment in that the shape of the drain socket 210A is slightly different.

As shown in FIG. 6, the flapper valve mechanism 220A includes a flapper valve 221A, a flapper valve rotation shaft 222A, and a weight 223A.
The flapper valve 221A includes a receiving portion 221Aa and a base end portion 221Ab.
The receiving portion 221Aa is formed in a substantially rectangular dish shape. The receiving portion 221Aa closes the drain port portion 102d by contacting the opening edge of the drain port portion 102d. The base end portion 221Ab is formed to extend from the rear side of the receiving portion 221Aa. A flapper valve rotation shaft 222A, which will be described later, is inserted into and fixed to the base end portion 221Ab.
The flapper valve rotation shaft 222A is provided on the rear wall 213Ad side of the drain socket 210A. The flapper valve rotation shaft 222A is substantially orthogonal to the direction in which the drain pipe 230 extends and extends substantially horizontally in the left-right direction, and is rotatably fixed to the left wall portion and the right wall portion of the drain socket 210A. Thus, the flapper valve 221A is rotated in a substantially vertical direction. That is, when the flapper valve 221A is opened, the receiving part 221Aa of the flapper valve 221A is arranged on the outlet part 215A side, so that the flapper valve 221A does not hinder the flow of sewage to the drain pipe 230. The position of the outlet portion 215A with respect to 221A is arranged below the first embodiment.
The weight 223A is provided closer to the base end 221Ab than the flapper valve rotation shaft 222A.

In the flapper valve mechanism 220A of the present embodiment, the flapper valve 221A rotates in the opening direction by the weight of the filth in the toilet bowl 102 and the accumulated water W. Thereby, the filth in the toilet bowl 102, the stored water W, etc. are discharged | emitted via the drain socket 210A and the drain pipe 230. FIG.
Further, according to the present embodiment, the effects (1), (2), and (5) described above are exhibited.
Although the illustration of the cleaning device is omitted in FIG. 6, the cleaning device 120 of the first embodiment may be applied in this embodiment, and the cleaning device 120 may not be provided (FIG. 7, 8 is also the same).

[Third Embodiment]
FIG. 7 is a partial cross-sectional side view schematically showing a toilet apparatus 1B according to the third embodiment of the present invention.
The toilet device 1B according to the present embodiment is the same as that of the second embodiment except that the shape of the drain outlet 102Ad of the toilet bowl 102A in the toilet 100A is different and the shape of the drain socket 210B is accordingly different. .

As shown in FIG. 7, the drain outlet 102Ad of the toilet bowl 102A is formed so as to open obliquely downward and downward rather than downward. Specifically, the drain port portion 102Ad extends in substantially the same direction as the direction in which the drain pipe 230 extends. Thereby, since the sewage discharged | emitted from the drain port part 102Ad flows straight into the drain pipe 230 as it is, drainage performance is improving more.
Also in this embodiment, the inflow port portion 214B of the drain socket 210B is provided on the upper surface portion 211B constituting the upper portion of the drain socket 210B, and a part thereof extends to the front wall portion 213Ba.
According to the present embodiment, the operation is the same as in the second embodiment, and the same effect is produced.

[Fourth Embodiment]
FIG. 8 is a partial cross-sectional side view schematically showing a toilet device 1C according to the fourth embodiment of the present invention.
The toilet device 1C according to the present embodiment is the same as the second embodiment, except that the flapper valve rotation shaft 222A is provided not on the rear wall 213Ad side but on the front wall 213Aa side.
According to the present embodiment, the effects (1), (2), (3) and (5) described above are exhibited.
