Description

The present invention relates to a wall-mounted toilet bowl in which the rear side of the toilet body is attached to a wall surface and fixed.

壁 Wall-mounted toilets have been used not only for public but also for detached houses because of their excellent cleaning properties such as the floor of the toilet room. The structure of a conventional wall-mounted toilet will be described with reference to FIGS. In FIG. 16, the toilet main body 1 is configured such that the mounting surface 2 on the rear side of the toilet main body 1 is attached to the wall surface 3 in close contact. For mounting on the wall 3, a bolt 4 fixed to the wall 3 is inserted through a bolt hole 6 formed in a mounting ear 5 on the back side of the toilet body 1, and a decorative nut 7 is mounted on the bolt 4 penetrating into the toilet room. Do it. Further, as shown in FIG. 17, the rib of the bolt hole 6 is a rib of a tubular shape, or as shown in FIG. I have. In FIG. 16, reference numeral 8 denotes a flange for connecting a toilet pipe (not shown) communicating with sewage and the like and a drain port 9 of the toilet body 1.

FIG. 19 is a sectional view of the toilet body, which is composed of a rim 13 and a trunk 14. Although the toilet body is manufactured by casting, usually, the rim 13 and the body 14 are separately formed, and after molding, the toilet body is manufactured by laminating. FIG. 20 shows the mold structure of the body, which is composed of a bowl mold 26, a back mold 27, a side (left) mold 28 and a side (right) mold 29. Although not shown, the rim mold structure is composed of an upper rim upper mold and a lower rim upper and lower mold. As described above, conventionally, many split types have been used. (For example, see Patent Document 1)

Japanese Patent No. 2,593,591 (page 3, FIG. 3)

型 As mentioned above, the molds that constitute the body usually require four molds. Further, the cylindrical ribs 11 of the bolt holes 6 formed in the mounting ears 5 shown in FIG. 17 are often bonded separately, and the number of molds is four, and the number of molds is up to the forming die of the member to be bonded. If you include it, it will increase further.

An object of the present invention is to provide a wall-hung toilet with a simplified mold configuration and improved productivity.

In order to achieve the above object, according to the first aspect of the present invention, in a wall-mounted toilet in which a rear portion of a toilet body is attached to a wall surface and fixed, a body constituting the toilet is formed into a bowl type and a bottom type. And at least one of the mating surfaces is located at a position corresponding to the center of the drain port.

According to the present invention, the formation around the drain port on the mounting surface of the body has conventionally been configured with a back mold. By using a bottom mold, it is possible to mold the periphery of the drain port and the mounting surface, and the need for the back mold is eliminated, thereby enabling a two-mold construction.

According to the second aspect, the mounting space for mounting the wall-hung toilet to the wall is formed as a bowl-shaped one of the two types of the body, so that the mounting ear is conventionally provided on the rear surface of the toilet. , The mounting ears are formed by the left and right side molds, and in an unnecessarily large space, the appearance was not good, but without obstructing the appearance line of the trunk Since a toilet body having continuity can be formed, a shape excellent in design can be formed. Further, by providing the lower surface position of the mounting space above the pool surface of the body, the occurrence of dew condensation in the mounting space can be avoided.

According to the third aspect, an air layer is formed outside the reservoir section of the body so that dew condensation on the outer surface of the toilet body can be prevented. Many conventional wall-mounted toilets have a structure in which the outer wall of the basin of the toilet directly contacts the atmosphere of the toilet due to weight reduction, etc. In addition, it is not preferable in terms of hygiene. In addition, the dew water transmitted from the bottom of the toilet to the wall also affects the corrosion of the wall material and the like, and the occurrence of dew is not preferable.

According to the fourth aspect, the peripheral rib of the mounting surface formed on the mounting surface of the wall-mounted toilet on the wall surface of the toilet body is not continuously formed on the entire circumference but is partially cut away. Features.
The peripheral rib is required when fixing the toilet bowl to the wall and distributing the load applied to the toilet bowl to the wall side. Even when a notch is formed in the lower part of the toilet, a space is formed between the toilet and the wall when the cutout is attached to the wall. The space below this, when urinating, comes off the bowl surface of the toilet, urine is transmitted down the toilet through the surface of the toilet, but is prevented by blocking it from reaching the wall surface, not pottery There is no need to worry about urine permeation into the material, and the occurrence of unpleasant odor and discoloration of the wall material is reduced.

According to the fifth aspect, the rib of the bolt hole formed on the mounting surface to the wall surface at the rear part of the toilet body is located on the rim side and is formed in the rim releasing direction, so that the conventional rib is bonded. This eliminates the need for the step of performing the process and the mold for forming the bonding member, thereby improving the productivity.

According to the sixth aspect, the ribs of the bolt holes formed on the mounting surface of the wall-mounted toilet on the rear wall surface of the toilet main body are widened toward the base, so that the mounting surface of the wall surface of the rear wall of the wall-mounted toilet body is formed. Prevent stress concentration. The way of spreading may be a tapered shape or a gentle round shape.

According to claim 7, a cavity is formed at least above the bolt hole formed on the mounting surface to the wall surface at the rear portion of the toilet body, and the mounting portion is reinforced together with the rib of the bolt hole.

In the eighth aspect, the joint portion with the hanger formed on the mounting surface of the wall-mounted toilet on the wall surface at the rear of the toilet body is located on the rim side, and is formed in the rim-type releasing direction. Generally, mounting ears are formed, and bolt holes and nuts are used to fix the mounting ears to the wall surface using bolts and nuts. However, by using a hanger type, labor for forming the bolt holes can be omitted. Further, it is possible to omit the bolting work at the time of construction. In addition, since the mounting holes are not provided for the bolts and the mounting portion is provided on the back surface of the toilet, the overall appearance of the toilet body can be finished with a smooth curve as a whole, so that a product with excellent design can be provided.

According to the mold configuration of the wall-mounted toilet of the present invention, a back mold, which was conventionally required, is not required, and a wall-mounted toilet with a simplified mold configuration and improved productivity can be provided.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a sectional view illustrating an embodiment of the present invention. The same reference numerals are used for the same parts as in the conventional example.

Reference numeral 1 is a toilet body. This toilet bowl is composed of a rim 13 and a body 14 at the boundary of II, and the body 14 is formed of two types, a bowl type 31 and a bottom type 33 described later. In the case of a conventional toilet, a back type is required, but the upper bowl type 32 and the lower bottom type 33 are arranged at a position corresponding to the center of the drain port 9 of the toilet in II-II. This is achieved by forming a two-type mold and setting the position as a mating surface. Further, according to this configuration, since the opening end of the drain port of the toilet bowl to be formed can be formed flush with the wall surface, there is an advantage that the joint with the pipe can be reliably performed. Reference numeral 23 denotes an air layer for preventing dew-proofing.

FIGS. 2 and 3 show the mold structure of the present invention. As shown in FIG. 2, the body 14 of the toilet body is formed into a bowl 31 and a portion 36 forming the bowl surface and the inner surface of the drainage channel of the bowl toilet. Is formed in the bottom mold 33 which is located inside. FIG. 3 shows the state of the bowl type and the bottom type when viewed from the directions of arrows M and L in FIG. The M direction is shown in a diagram, and the L direction is shown in b diagram. In the bottom mold 33, a portion 35 that forms the outer shape of the toilet body 14 and the lower part of the outer periphery of the toilet drain port is formed. A bowl-shaped portion 34 is formed at a bowl-shaped position facing the portion 35, as shown in FIG.

Further, in the bowl mold 31, the toilet bowl / drain passage inner peripheral portion 36, the drain port outer peripheral upper portion 34, the mounting surface of the toilet body rear portion, and the mounting space 22 are formed 32. .
In forming the drain port, a plug type (not shown) may be used to secure the strength around the drain port. Since it can be used much more easily than providing a back mold and does not hinder productivity, it can be used as appropriate.

Although the details of the manufacturing method are omitted, for example, the molding method can be achieved by using ordinary casting. That is, the above-mentioned shape is formed, and the sanitary ware material is slurried into the formed space, and if necessary, pressurized. The slurry is discharged from the space, and then the mold is opened and the molded body is taken out. As a molded body, a toilet bowl and a rim portion are separately formed, and they are joined to form a toilet bowl molded body, and then dried, glazed, and fired to manufacture a toilet bowl.

FIG. 4 is a view showing a rear part of the toilet of the present invention.
The wall-mounted toilet (see FIG. 16) is configured such that the mounting surface 2 on the rear side of the toilet body is attached to the wall surface 3 in close contact. Ribs 16 are provided on the left and right sides of the bolt holes 6 in the mounting surface 2, and the ribs 16 are integrally formed in a rim shape. The joint between the lower part of the rib 16 and the rear surface of the toilet body has a smooth round shape so as to spread toward the base of the rib, thereby preventing concentration of stress. Note that a tapered shape may be used instead of the round shape.

に は Further, a water reservoir 21 having a U-shaped cross section is provided at the water supply port of the toilet rim. As shown in FIG. 5, the pool 21 considers the connection of the spuds 40, which are necessary members for connecting the flush pipe 18 to the toilet body, and is further considered to be generated by water pooled in the pool. The shape of the U-shape is determined so as to suppress the occurrence of dew condensation. In particular, the spuds may be shipped inside the toilet when it is shipped, so it is desirable to design the spuds so as to fit in the toilet so that the washing tube mounting side of the spuds is not exposed from the mounting surface as shown in FIG.

In addition, since the bottom wall of the water pool 21 is common to the outer wall of the drain port 9, that is, it is isolated from the atmosphere in the toilet, dew condensation rarely occurs. The condensed water generated on the bottom wall of the drain 21, that is, the condensed water generated on the inner wall of the drain port is discharged from the drain port, so that the surface of the toilet can be prevented from being generated. In addition, although the toilet has a water pool, the depth of the U-shaped portion is set on the inner bottom surface of the washing pipe so that the water pool does not occur.

Further, the water pool depth of the water pool portion of the rim water supply port portion is adjusted so that the water pool depth does not reach the lower end position of the washing pipe connected to the rim water supply port and leading water supply from the tank and the flush valve. By setting, dew condensation from the washing tube itself is prevented.

FIG. 6 is a view showing a case where the above-mentioned toilet body is not directly mounted on a wall but is mounted via a cabinet 19. The mounting ears 5 are provided on the rear side surface of the toilet as the mounting space 22 when the toilet main body 1 is mounted on the front plate surface 19a of the cabinet. Since the position of the bottom 22a of the mounting space 22 is located above the water level in the bowl, the occurrence of dew condensation in the mounting space is avoided. The cabinet houses a tank 17 for storing and supplying flush water to the toilet, and a flush pipe 18 for guiding the flush water from the tank 17 to the toilet. Although not shown, flush water may be supplied to the toilet from the flush valve, and a water supply device is selected according to various conditions.

The toilet bowl cross-sectional view shown in FIG. 7 shows a state in which an air layer 23 is formed between the bowl surface (reservoir portion) of the toilet and the outer wall of the toilet. It plays the role of not transmitting the water temperature of the pool to the surface of the toilet, preventing the occurrence of condensation. In addition, in forming the air layer, the outer shape of the body draws a smooth curve, and the appearance design becomes clear and has a good appearance.

FIG. 8 is a partial cross-sectional view taken along the line AA of FIG. 4, showing the upper cavity 50 of the bolt hole formed on the mounting surface on the wall surface at the rear of the toilet body. The periphery can be reinforced not only by the ribs 16 but also by the thickness formed by the cavity 50. The cavity 50 may be located not only above the bolt hole but also on the left and right, and can be set arbitrarily.

FIG. 9 shows an embodiment in which a stagnation portion 24 is provided in the rim water passage, inside the rear rim of the rim water supply hole for supplying washing water to the bowl. This is based on the natural phenomenon that when the washing water in the rim flows with a certain momentum, it flows along the side wall of the rim. Propagation causes a speed difference in the flow itself, which allows the directionality of the flow to be controlled. As a result, an effect that the thickness of the flow whose direction is changed can be adjusted in proportion to the size of the stagnation portion can be expected.

Next, another embodiment of the ball type will be described with reference to FIGS. The same reference numerals are used for the same parts as in the above embodiment.
FIG. 10 is a diagram corresponding to FIG. The opening of the drain port is positioned so as to be substantially flat, without the cylindrical portion (projection) of the drain port as in the above-described embodiment, at a position away from the wall surface as compared with the above-described embodiment. ing. Therefore, since there is no portion (projection) that hinders the removal of the mold, the mating surface between the bowl mold and the bottom mold can be set at any position. In this case, if the bowl type or the bottom type is located at the portion corresponding to the drain opening, after removing the mold by leaving the portion located at the bowl type or the bottom type drain opening at the non-water supply state. An opening can be formed. Alternatively, the opening can be formed by cutting off the drain opening portion that is closed after the mold release.
Reference numeral 1 is a toilet body. This toilet bowl is composed of a rim 13 and a body 14 at the boundary of II, and the body 14 is formed of two types, a bowl type 31 and a bottom type 33 described later. Reference numeral 23 denotes an air layer for preventing dew-proofing.

FIGS. 11 and 12 show the mold structure of the present invention. As shown in FIG. 11, the body 14 of the toilet body is formed into a bowl shape 31 and a portion 36 forming a bowl surface and an inner surface of a drainage channel of the bowl shape toilet bowl. Is formed in the bottom mold 33 which is located inside. FIG. 12 shows the state of the bowl type and the bottom type when viewed from the directions of arrows M and L in FIG. The M direction is shown in a diagram, and the L direction is shown in b diagram. Reference numeral 37 of the bowl mold 31 is a back surface portion that is fitted with the bottom mold 33 so as to cover the end face of the drain opening, and can be aligned with the bottom mold at an arbitrary position. It can be set appropriately. For example, when partially cutting out the peripheral rib used for fixing to the wall surface described in the above embodiment, the bottom mold does not have a portion corresponding to the peripheral rib, and is formed only in the bowl mold. What is necessary is just to mold and shape | mold. In the bottom mold 33, a portion 35 that forms the outer shape of the toilet body 14 and the lower part of the outer periphery of the toilet drain port is formed. At the bowl-shaped position facing the portion 35, a portion forming the upper part of the outer periphery of the toilet drain port is formed as a part 34 of the bowl-shaped portion 36 as shown in FIG.

FIG. 13 is a diagram illustrating the rear part of the toilet according to the present embodiment.
