Description

  The present invention relates to a drainage structure for a flush toilet.

  In flush toilets, a cleaning method is known in which cleaning water is discharged from one or more water outlets to the toilet bowl, and filth is pushed out to a drain pipe (sewer) by the force of the cleaning water. A storage part for storing washing water is formed at the bottom of the toilet bowl. The storage unit is connected to a drain pipe (hereinafter simply referred to as “outer pipe”) installed outside the toilet bowl via a drain pipe (hereinafter simply referred to as “inner pipe”) incorporated in the toilet bowl. The inner tube is often formed as a trap tube having a bent structure that once rises and then rises.

  The inner pipe can be roughly divided into “integrated type” and “separated type”. In the integrated type, the stool portion and the inner tube are completely formed integrally (see Patent Document 1). The inner tube integrally formed with the toilet bowl is directly connected to the outer tube. In the separation type, only the toilet bowl and a part (upstream part) of the inner tube are integrally formed. This partial inner pipe is connected to the outer pipe via a separate part called a drain socket (see Patent Document 2).

JP 2014-045771 A International Publication No. 1998/030761

  In the case of the flush toilet shown in Patent Document 1 (integrated type), the toilet drainage channel 30 (inner pipe) is manufactured by integral molding as a part of the toilet body, so that the manufacturing cost can be reduced. In addition, if the drainage port 32 of the toilet drainage channel 30 (inner pipe) is aligned with the drainage pipe 70 (see FIG. 2, outer pipe) on the wall surface of the toilet room, the installation position is determined, so that construction is easy. On the other hand, since it is integrally molded with the toilet body, the shape of the toilet drainage channel 30 tends to vary. In particular, since pottery has a relatively large manufacturing variation, when the toilet bowl and the inner tube are formed of pottery, the variation in the inner tube tends to be large.

  In the case of Patent Document 2 (separate type), the trap device 10 (drain socket) is fixed in advance to the floor surface of the toilet room, and the falling pipe 6 (upstream part of the inner pipe) of the toilet body 1 is placed from above. A flush toilet is attached to the toilet room by fitting. Because of the separation type, the trap device 10 can be molded from a material that is easy to manufacture, for example, vinyl chloride. There is a merit that manufacturing variation of the inner pipe can be suppressed. On the other hand, the operation of lifting the toilet body 1 and aligning the falling pipe 6 and the upstream connecting pipe 11 of the trap device 10 is burdensome. And since the back surface of the toilet bowl body 1 of patent document 2 is open | released largely (refer FIG. 1), the trap apparatus 10 cannot fully be shielded. It is not preferable from the viewpoint of safety and hygiene that the inside of the toilet body 1 is opened. For example, since vinyl chloride is vulnerable to heat, if the back surface of the toilet body 1 is opened, external heat is directly transmitted to the trap device 10 (drain socket).

  The present invention has been made on the basis of the above-mentioned problem recognition, and its main object is to propose a separate inner pipe structure that can be easily constructed in a flush toilet.

In order to solve the above-described problems, a flush toilet according to an aspect of the present invention includes a toilet bowl member and a toilet member formed with a toilet drain pipe connected to the toilet bowl portion, and a drainage formed separately from the toilet member. A socket.
A through-hole is formed in the back surface of the toilet member, the intake port of the drain socket is connected to the toilet drain pipe, and the drain port of the drain socket is aligned with the through-hole.

  Another aspect of the present invention is a toilet member. This toilet member is integrally formed with a toilet bowl, an inner pipe connected to the toilet bowl, and a shielding part that conceals the side and back of the inner pipe, a through-hole is formed in the shielding part on the back side, and the inner pipe And the through hole are separated.

  Yet another embodiment of the present invention is a method for producing a flush toilet. This method includes the steps of integrally molding a toilet bowl member and a toilet member having a toilet drain pipe connected to the toilet bowl section, and forming a through-hole in the back surface by perforating the back surface of the toilet member. .

  ADVANTAGE OF THE INVENTION According to this invention, it becomes easy to reduce the construction work burden of the flush toilet bowl which has a separation type inner pipe.

The flush toilet 100 in the present embodiment is a separation type in which a part of the inner pipe (suction pipe 110) integrally formed with the toilet member 108 (toilet body main body) is connected to the relay pipe 120 and the drain socket 122. The combination of the suction pipe 110 and the relay pipe 120 forms a “toilet drain pipe”, and the combination of the toilet drain pipe and the drain socket 122 forms an “inner pipe”. The suction pipe 110 and the relay pipe 120 may be integrally formed, or the suction pipe 110 and the relay pipe 120 may be formed as separate parts. That is, the toilet drainage pipe may be integrally formed with the toilet member 108 as a whole, or only the suction pipe 110 that is a part of the toilet drainage pipe may be integrally formed with the toilet member 108. Although the inner tube in the present embodiment is described as being a trap tube 124, it is not essential that the inner tube has a bent shape as the trap tube 124. The “toilet member 108” in the present embodiment is a main part of the flush toilet 100 including the outer wall surface 114, the toilet bowl 106, and the storage 126, but the relay pipe 120 and the drain socket 122 are excluded.
The toilet member 108 is made of earthenware, and the relay pipe 120 and the drain socket 122 are made of vinyl chloride resin. Since vinyl chloride resin has higher processing accuracy than pottery, it is easy to stabilize the quality of the drainage structure of flush toilet 100.

FIG. 1 is a front perspective view of a flush toilet 100. FIG. 2 is a rear perspective view of the flush toilet 100.
A toilet bowl 106 is formed on the toilet member 108 (toilet body) of the flush toilet 100. The toilet member 108 incorporates a tank (not shown) and a pump (not shown). The communication hole 118 communicates a water supply pipe (water supply). Wash water taken from the water supply pipe is stored in a tank. The pump supplies cleaning water stored in the tank to the first water outlet 102 and the second water outlet 104. The first water outlet 102 and the second water outlet 104 discharge cleaning water to the toilet bowl 106.
The toilet member 108 in this embodiment is made of earthenware. Pottery is highly durable and robust, and has the advantage of being less susceptible to dirt and easy to clean.

  Although the flush toilet 100 has an open bottom surface, the outer surface of the side surface is covered with an outer wall surface 114. In other words, the internal structure of the toilet member 108 is shielded from the outside. A communication hole 118 and a through hole 116 are perforated on the back surface of the toilet member 108. The communication hole 118 is connected to the water supply (water supply pipe), and the through-hole 116 is connected to the sewer (outer pipe). A drain port 130 of a drain socket 122 (described later in detail) built in the toilet member 108 is aligned with the through port 116. The drain socket 122 is connected to an outer pipe (not shown) formed on the wall surface of the toilet room through the through-hole 116.

  The ratio of the opening area of the drain port 130 of the drain socket 122 to the opening area of the through hole 116 is desirably 90 to 110%. The gap between the drain port 130 and the through-hole 116 is preferably shielded by packing (details will be described later). With this configuration, the internal structure of the toilet member 108 is completely shielded from the outside.

FIG. 3 is a side sectional view of the flush toilet 100.
A storage portion 126 for storing washing water is formed at the bottom of the toilet bowl portion 106, and a suction tube 110 is formed in the upward direction from the storage portion 126. The toilet bowl part 106, the storage part 126, and the suction tube 110 are integrally formed as a part of the toilet member 108. The outlet 132 of the suction pipe 110 opens in the horizontal direction (x-axis negative direction), and the relay pipe 120 is connected to the outlet 132. The relay pipe 120 is a bent pipe that opens in the horizontal direction on the upstream side and opens in the downward direction (z-axis negative direction) on the downstream side. The relay pipe 120 in this embodiment is made of a vinyl chloride resin. A drain socket 122 is connected to the downstream opening of the relay pipe 120. The drain socket 122 is a bent pipe having a water intake port 128 that opens upward (z-axis positive direction) and a drain port 130 that opens horizontally (x-axis negative direction). A water intake 128 which is an upstream opening of the drain socket 122 is connected to the relay pipe 120, and a water outlet 130 which is a downstream opening is fitted into the through hole 116. The material of the drain socket 122 is also vinyl chloride resin. Although details will be described later, a packing 134 is fitted into the water intake port 128, and a packing 134, a packing 148, and a non-combustible material 154 are fitted inside and outside the drain port 130. The packing 148 is installed between the inner wall of the outer tube 146 and the outer wall of the drain socket 122, and the non-combustible material 154 is installed between the outer wall of the outer tube 146 and the inner wall of the through hole 116. The non-combustible material 154 is a member for protecting the outer tube 146 when the outer tube 146 is a combustible material (such as vinyl chloride resin). Further, the noncombustible material 154 fills the gap between the through hole 116 and the outer tube 146. The non-combustible material 154 is not essential when the outer tube 146 is a non-combustible material.

  Since the bottom of the drain socket 122 is at a lower position than the bottom of the reservoir 126, a siphon effect is exerted on the trap pipe 124 (inner pipe) formed by the combination of the suction pipe 110, the relay pipe 120 and the drain socket 122. . Due to the siphon effect, filth and water collected in the reservoir 126 are pushed out from the drain port 130 to the sewer (outer pipe). In order to generate the siphon effect, the structure of the drain socket 122 is particularly important. In the present embodiment, the manufacturing variation of the trap tube 124, in particular, the manufacturing variation of the draining socket 122 that strongly influences the siphon effect, is suppressed by forming the drainage socket 122 with high processing accuracy vinyl chloride resin. .

  The relay pipe 120 need not be a separate part. For example, not only the suction pipe 110 but also the relay pipe 120 may be integrally formed as a part of the toilet member 108. Alternatively, the relay pipe 120 and the drain socket 122 may be formed as a single part.

FIG. 4 is a side sectional view of the toilet member 108.
When the toilet member 108 is manufactured, the storage portion 126 and the suction tube 110 are simultaneously formed as a part thereof. After the toilet member 108 is molded or fired, a through-hole 116 and a communication hole 118 are formed in the back surface. In the toilet member 108, the suction pipe 110 (toilet drain pipe) is separated from the through-hole 116. The uppermost point of the suction pipe 110 is an outlet 132, and the relay pipe 120 shown in FIG.

FIG. 6 is a front perspective view of the drain socket 122. FIG. 7 is a rear perspective view of the drain socket 122.
The drain socket 122 is a bent pipe member that connects the intake port 128 that opens upward and the drain port 130 that opens to the side. The drain socket 122 has a pipe portion 142 and a pedestal 138. A rubber packing 148 (sealing material) is fitted into the drain port 130, and the gap between the drain port 130 and the through port 116 is shielded by the packing 148. The packing 148 prevents foreign substances such as insects from entering the toilet member 108 from the gap between the through hole 116 and the drain port 130. A packing 134 is also attached to the water intake port 128 to ensure the connection between the relay pipe 120 and the water intake port 128. Although it is desirable that the packing 148 has fire resistance, it is not essential.

  A pedestal 138 is connected below the pipe portion 142. The base 138 is installed on the floor and supports the drain socket 122 and the relay pipe 120. The pedestal 138 may be screwed to the floor of the toilet room. Two fixing members 140a and 140b are attached to the rear part of the base 138, and the fixing members 140a and 140b are screwed to the back surface of the toilet member 108 (see also FIG. 2). The flush toilet 100 is fixed to the toilet room by fixing the base 138 of the drain socket 122 to both the floor surface of the toilet room and the toilet member 108 by screws.

Finally, a method for manufacturing the flush toilet 100 will be described.
(1) The toilet member 108 is formed by integral molding.
(2) After the toilet member 108 is formed, the communication hole 118 and the through-hole 116 are drilled in the back surface of the toilet member 108 with a drill or the like.
(3) The relay pipe 120 is fixed to the outlet 132 of the suction pipe 110 with screws.
(4) The drain socket 122 is attached to the relay pipe 120 while the drain port 130 of the drain socket 122 is aligned with the through-hole 116. The packing 148 and the incombustible material 154 may be attached to the drain port 130 in advance, or the gap between the drain port 130 and the through-hole 116 is shielded with a putty (sealing material) after the drain socket 122 is attached to the relay pipe 120. May be. The fixing member 140 of the drain socket 122 is fixed to the toilet member 108 with a screw.
Through the above operation, the relay pipe 120 and the drain socket 122 are attached to the toilet member 108, and the trap pipe 124 that communicates the through hole 116 from the storage portion 126 is constructed. The operations (1) and (2) are manufacturing operations performed before the toilet member 108 is shipped. (3) (4) may also be performed as part of the manufacturing operation, but may also be performed as an on-site construction operation.

  After the through hole 116 of the flush toilet 100 is aligned with the outer pipe of the wall of the toilet room from the lateral direction, the pedestal 138 is fixed to the floor surface of the toilet room with screws, thereby fixing the flush toilet 100 to the toilet room. Is done.

8 and 9 are side sectional views of the vicinity of the drain port of the drain socket in the first configuration example. FIG. 9 schematically shows a fire prevention method when the flame 152 enters from the outer tube 146 in the first configuration example.
The drain socket 122 is partially inserted into the outer tube 146. The gap between the drain port 130 and the outer tube 146 is shielded (sealed) by a rubber packing 148 (sealing material). In the first configuration example, the incombustible material 154 between the through-hole 116 and the outer wall portion of the outer tube 146 functions as a fireproof member.

  It is assumed that a flame 152 enters the flush toilet 100 from the outer tube 146 when a fire occurs. In this case, the drainage socket 122 made of vinyl chloride resin is melted, but the toilet member 108 is made of earthenware and therefore does not melt. Also, the outer tube 146 usually has fire resistance. In the first configuration example, the non-combustible material 154 fills the gap between the through-hole 116 (outer wall surface 114) and the outer tube 146, so that the flame 152 does not leak from the gap. That is, even if the flame 152 of the outer tube 146 enters the flush toilet 100, it is difficult for the flame 152 to spread out of the flush toilet 100.

10 and 11 are side sectional views of the vicinity of the drain outlet of the drain socket in the second configuration example. FIG. 11 schematically shows a fire prevention method when the flame 152 enters from the outer tube 146 in the second configuration example.
In the second configuration example, the fire prevention member 150 is installed outside the drain socket 122. The fire prevention member 150 in the second configuration example is a known plastic refractory material that expands several times to form a heat insulating layer when a fire occurs. In the event of a fire, the drain socket 122 made of vinyl chloride resin melts away, but the fire protection member 150 expands with heat and shields the through hole 116. Since the fire prevention member 150 blocks the through-hole 116, the flame 152 cannot enter the flush toilet 100.
A combination of the first configuration example and the second configuration example is also possible.

As described above, the structure of the trap tube 124 of the flush toilet 100 has been mainly described based on the embodiment.
In the case of a flush toilet having a large opening on the back as in Patent Document 2, foreign matter such as insects may enter the toilet body from there. In the flush toilet 100 of this embodiment, the relay pipe 120 and the drain socket 122 that constitute the trap pipe 124 are shielded by the outer wall surface 114. Each of the communication hole 118 and the through-hole 116 is an opening that is drilled, and is not a notch that opens to the floor. By the packing 148 and the non-combustible material 154, the drain port 130 and the through port 116 are attached without a gap. Since the relay pipe 120 and the drain socket 122 are completely shielded by the outer wall surface 114, it is difficult for external heat, for example, heat at the time of a fire to be transmitted to the relay pipe 120 and the drain socket 122. Although the vinyl chloride resin is vulnerable to heat, the relay pipe 120 and the drain socket 122 can be protected by the pottery member 108 made of earthenware having high heat resistance. In addition, since foreign substances such as insects and dust are less likely to enter the toilet member 108, there is a hygienic advantage. If the nonflammable material 154 or the fireproof member 150 having fireproof performance is attached, it becomes easier to further prevent the flame 152 from spreading.

  In addition, instead of attaching the drain socket 122 to the toilet room and aligning the toilet member 108 from above, the relay pipe 120 and the drain socket 122 are attached to the toilet member 108 in advance, and then the flush toilet 100 is attached. Is installed in the toilet room. Since the communication hole 118 formed on the back surface of the toilet member 108 is connected from the side to the outer tube on the wall surface of the toilet room, it is not necessary to lift and align the toilet member 108 as in Patent Document 2. For this reason, the work burden at the time of installing the flush toilet 100 in a toilet room is reduced.

  The present invention has been described based on some embodiments. Those skilled in the art will understand that these embodiments are examples, and that various modifications and changes are possible within the scope of the claims of the present invention, and that such modifications and changes are also within the scope of the claims of the present invention.
