Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a flush toilet, and more particularly, to a structure of a water supply portion for supplying flush water of the flush toilet.
[0002]
[Prior art]
Conventional methods for supplying flush water to flush toilets include a tank type in which flush water is stored in a tank and a direct water supply system in which flush water is supplied directly from a water pipe.
[0003]
In the tank type, water supplied from a water pipe is once stored in a tank, and the flush water is supplied to a flush toilet by opening a drain valve in the tank. For this reason, the flush toilet can be washed regardless of the supply condition of tap water, so that the flush toilet can be washed without problems even if the pipe pressure is low and the supply amount per hour is small. It is installed in general houses such as apartment houses and detached houses.
[0004]
Further, since the water stored in the tank generally has a depth of 200 to 300 mm, the water head pressure is as small as about 0.002 to 0.003 MPa, and the potential energy of the washing water is efficiently transmitted to the flush toilet during washing. Needed. For this reason, various measures have been taken to increase the diameter of the drain valve to ensure the flushing ability of the flush toilet even at a small pressure.
[0005]
On the other hand, the direct water supply type is generally installed in a building with good plumbing conditions such as public facilities, and the tap water supply condition has a capacity of 0.07 MPa or more, so there is some resistance to the shape of the flush water passage section in the flush toilet. Even if there is, the flow rate was maintained by the energy of the pressure, and the flow rate per short time was not greatly reduced. Therefore, no problem occurred in the washing function.
[0006]
As described above, it is difficult to use a common flush toilet because the supply condition of the flush water is different between the tank type and the direct water pressure type.
[0007]
Regarding the common use of flush toilets, a proposal has been made for common use of toilets by allowing a spud to be attached to a water supply port of a tank-type flush toilet (for example, Patent Document 1).
[0008]
[Patent Document 1]
Japanese Utility Model Laid-Open No. 04-53865 (page 4, FIG. 1)
[0009]
[Problems to be solved by the invention]
In the above-mentioned prior art, although the common use of the toilet bowl was achieved, after supplying the wash water from the tank or the flush valve, using the siphon action, together with the wash water / dirt, the water from the drain pipe was placed in the bowl of the flush toilet. After the siphon operation is finished, the flush water for the flush water cannot be supplied to the siphon toilet of a type in which the accumulated water stored for the purpose of blocking the odor is also drawn toward the drain pipe.
[0010]
An object of the present invention is to provide a common water supply structure and to propose a water supply structure capable of supplying flush water regardless of a toilet flushing method (siphon type, wash-down type, etc.).
[0011]
[Means for Solving the Problems]
The present invention has been made on the basis of the above-mentioned problems, and has a flush toilet, a washing means for supplying flush water to the flush toilet, and a water guide unit for connecting the flush means and the flush toilet in a watertight manner. The water guide section has an attachment hole for attaching the washing means, and a connection hole for connection to the flush toilet, and an extension section for temporarily storing washing water between the attachment hole and the connection hole. The gist of the present invention is a flush toilet characterized by forming a flush toilet.
[0012]
According to the present invention, a complicated water supply condition adjusting function section is provided on the cleaning means side or the flush toilet side by providing a water guide section between the cleaning means (tank type, water supply direct pressure type) and the flush toilet. In addition, since it is possible to cope with the problem by making it possible to appropriately adjust the mounting hole and the connection hole of the water guiding portion having a simple structure, the toilet can be shared, and the water supply condition of the washing water can be kept constant. Further, since the water introduction section is formed with an extension section for temporarily storing washing water, even in the case of a siphon toilet, the washing water stored in the extension section flows out after the siphon action is completed, and the accumulated water flows out. Can be formed.
[0013]
In addition, the connection hole has a flow rate adjusting function that can adjust the flow rate of washing water supplied to the flush toilet by changing the opening diameter or disposing a mesh such as a strainer, etc. In this case, a sufficient flow rate can be provided.
[0014]
In addition, since the mounting hole is opened in the horizontal direction with respect to the floor, the clearance of the water guide portion can be larger than in the flush toilet where the mounting hole is opened in the vertical direction with respect to the floor, so that the degree of freedom in design is improved. . Therefore, the appearance can be made compact, and the amount of flowing water in the expansion section can be adjusted as appropriate. In addition, the water guide can be used as a fixed base for the tank.
[0015]
Further, the flush toilet is a wall-mounted toilet separated from the floor, and the water guide portion is integrated with the wall-mounted toilet and the washing means.
[0016]
According to the present invention, in general, a flush pipe is used for a water guiding section connecting a tank and a flush toilet in a wall-mounted toilet, but in a wall-mounted toilet, since the flush pipe is set on the back side, it is difficult to fix, and fixing is difficult. Although it was sufficient and the possibility of causing water leakage was not small, by integrating the tank and the flush toilet with the water guide part with bolts or the like, the possibility can be reduced as much as possible.
[0017]
In addition, the water guiding unit moves up and down integrally with the wall-mounted toilet and the washing means.
[0018]
According to the present invention, in a flush toilet in which a wall-hung toilet generally moves up and down, a bellows hose is used to connect the tank and the flush toilet. However, when the flush toilet is moved up and down, a bellows hose is twisted. Although there was a possibility, the problem of the bellows hose can be eliminated by integrating the tank and the flush toilet into the water guide section with bolts or the like.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a wall-mounted flush toilet 1 connected to a cabinet 2 showing a first embodiment according to the present invention, FIG. 2 is a central sectional view in FIG. 1, and FIG. FIG. 4 is a sectional view taken along line N-O in FIG.
[0020]
In FIG. 2, the water supply port 17 of the flush toilet 1 is opposed to the connection hole 4 c of the water guide 4 concealed in the cabinet 2. 4 is fixed. Reference numeral 3 denotes a tank for storing washing water. The tank 3 has a drain port 3b of the tank 3 and a mounting hole 4b of the water guide section 4 opposed to each other. It is fixed to the part 4.
[0021]
Further, as shown in FIG. 3, the flush toilet 1 is fixed to the frame 5 via a toilet fixing bolt 9 so as to be separated from the floor 6. Since the mounting hole 10 into which the frame 5 and the toilet fixing bolt 9 are inserted is a vertically long hole, the flush toilet 1 can be moved up and down.
[0022]
The height A of the flush toilet 1 is generally set to about 370 to 380 mm, but a height of 40 to 50 mm higher than that is said to be easy for a physically handicapped person, and a height of 70 to 80 mm lower for a child. It is easy to use. Therefore, the height A can be freely changed according to individual users' requests.
[0023]
When the height A of the flush toilet 1 is changed in this manner, the tank 3 and the drainage unit 11 serving as a water supply unit connected to the toilet unit 1 also need to be moved up and down at the same time, but the drainage unit 11 has a vertically long connection portion 16. Thus, even when the flush toilet 1 moves up and down, the drainage section 11 can be fixed without moving the drainage section 11.
[0024]
On the other hand, the water supply section has a structure in which the tank 3 is firmly fixed to the flush toilet 1 via the water guide section 4, so that the tank 3 and the water guide section 4 move up and down together with the flush toilet 1. Therefore, there is no need to remove the packing 15 when the flush toilet 1 moves up and down, so that the flush toilet 1 can be surely moved without water leakage.
[0025]
Further, since the water guide section 4 is made of a strong material using a metal or the like, it can sufficiently withstand the load of the tank 3. When using a material such as resin which is slightly weaker in strength, the front lower end 3a of the tank 3 may be in contact with the rear upper portion 1a of the flush toilet 1 to distribute the load of the tank 3 to the flush toilet 1.
[0026]
Further, the method of manufacturing the flush toilet 1 is performed by baking with the wall surface 1b facing downward. In this case, if there is a pottery-made protrusion behind the wall surface 1b, it is very difficult to manufacture. Therefore, here, the water guide section 4 is a separate component, and there is no pottery-made protrusion on the rear side of the wall surface 1b. It has a simple structure. Although it is possible to add the function of a water guide to the toilet, it is possible to effectively use the space in the toilet room because the temporary storage of washing water impairs the external design of the toilet and the toilet itself becomes larger. There is a problem that it becomes impossible.
[0027]
Further, the water guide 4 has an extension 4 a that is a portion having a cross section larger than the drain 3 b of the tank 3. When the washing water 20 in the tank 3 is discharged from the drain port 3b by opening a drain valve (not shown), the washing water 20 reaches the extension 4a. However, since the volume is large, the flush water 20 is sufficiently stored in the extension 4a. Flows vigorously toward the water supply port 17. Then, water is discharged from a rim hole 18 a which is a hole of the rim 18, flows into the pool water 12, generates a siphon action, and the pool water 12 is discharged to the drain port 19. At this time, the position of the stored water surface 12a, which is the upper surface of the stored water 12 immediately after the cleaning, is lower than before the cleaning.
[0028]
Thereafter, the water temporarily held in the extension portion 4a is gradually discharged to the pool surface, and the pool surface 12a returns to the original position. In this way, the extension portion 4a temporarily holds the washing water 20 and gradually discharges the water after the end of the washing, thereby having an effect of returning the lowered water level 12a to the original position. Therefore, there is no need to provide a mechanism for restoring the water level of the stored water 12 with the metal fittings in the tank 3, so that the structure of the metal fittings inside the tank 3 can be simplified.
[0029]
Next, a connection structure between the building and the frame 5 will be described with reference to FIG.
Below the floor 6 is a concrete underfloor 31, which is a part of the building, and a wooden reinforcing material 32 connecting the underfloor 31 and the floor 6. Since the frame 5 needs to hold the load applied to the flush toilet 1, it is directly stopped below the floor 31 via the anchor bolt 33. With such a structure, the frame 5 can be firmly fixed without special reinforcement under the floor 6.
[0030]
Such a structure in which the underfloor 31 is made of strong concrete is generally adopted in an apartment house. However, even in a wooden detached house, since a beam which is a strong reinforcing material is generally used under the floor 31, a similar effect can be obtained by fixing the anchor bolt 33 to this.
[0031]
Next, a modification of the first embodiment is shown in FIG.
FIG. 5 is a central cross-sectional view of the flush toilet 1 when the flush valve 103 of the direct water supply type is used as the water supply means, and FIG.
[0032]
The flush toilet 1 is equivalent to the tank-type flush toilet 1 using the tank 3 shown in the first embodiment, and the drain unit 11 is also equivalent. Further, the flush valve 103 and the flush toilet are fixed in a watertight manner via a water guiding section 104. In the water guide portion 104, a mounting hole 104a for positioning the discharge port 103b of the flash valve 103 and a connection hole 104c of a connection portion connected to the water supply port 117 of the flush toilet are connected with a slightly smaller diameter than in the case of the tank type. Have been.
[0033]
The water pressure of the direct water supply type is 0.07 MPa or more, and the head pressure of the tank type is about 0.003 MPa. Since the supply water pressure is a force for maintaining the flow rate, which is the amount of water per unit time, the flush water 20 discharged from the rim hole 18a is more vigorous in the tap water direct pressure type, but by reducing the inner diameter of the connection hole 104c. By reducing the inner diameter of the water supply port 117, the flow rate is reduced to supply a flow rate substantially equal to that of the tank type. Therefore, since the amount of the flush water 20 supplied to the flush toilet 1 can be adjusted in advance, the flush toilet 1 can be shared by the direct water pressure type and the tank type.
