Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet bowl which can be used as a flush toilet or a simple flush toilet.

[0002]

2. Description of the Related Art In a conventional flush toilet, a water seal trap is provided inside the toilet to block odor from a drain pipe connected to a lower portion, and when flush water flows in during use, the water level on the bowl surface rises. As a result, the water in the trap flows out, and the water in the bowl flows out to the downstream drain pipe together with the waste due to the siphon phenomenon. In a general flush toilet, only wastewater accumulated in the bowl surface is flushed away by running water, so that 8 to 10 liters of flush water is required to flush the waste that has previously entered the drain pipe until it reaches the sewer main pipe. In addition, even a siphon toilet or a siphon jet toilet, which has a relatively high carrying capacity for storing 3 to 4 liters of water in a bowl and flowing it together with filth, can be used in the bowl.
After flushing a liter of water at a time, the water flow is weak and wasteful water is flowing in order to flush the water from the water supply for a certain period of time.

Another drawback of siphon toilets and siphon jet toilets is that there is a deodorant trap in the duct in the toilet, which not only prevents drainage but also causes a siphon action to drain the water on the bowl surface of the toilet bowl at once. For flushing, various projections and resistors were provided in the duct in the toilet below the trap section, and it was inevitable that the momentum of drainage would weaken. In addition, the trap for trapping water in the toilet bowl by natural atmospheric pressure has a long history and is considered to be the best method at present.However, the sealing water is sucked or scattered due to the pressure applied from inside the drain pipe, and the water is sealed. There is a need for a deodorizing method that does not fluctuate due to the pressure in the pipeline because the performance may be broken. As described above, it is necessary to solve the above-mentioned problem by using a toilet having a deodorizing structure in which the flushing power of the flush toilet is increased, the drainage is efficiently performed, and there is no fear of breaking.

There is a simple flush toilet for such flush toilets. This simple flush toilet has a drainage deodorant structure specified by JIS standards and regulations of the Minister of Construction. The odor is blocked by suppressing the toilet port on the toilet bowl surface with a plate-shaped shield, or by storing a small amount of water around the dish that blocks the toilet port and sealing it with water. And the filth falls and is stored together with a small amount of washing water in the pumping tub provided at the bottom of the toilet,
Considering the capacity of the toilet tank, the amount of washing water is extremely small,
It is set to 00 to 500 cc. Assuming that this simple flush toilet is used as a flush toilet, the weight balance of the shield is set to the amount of water that almost fills the bowl surface, and the shield is set to open at once when the water amount on the bowl surface reaches the balance water amount Keep it. When using as a simple flush toilet, operate the water supply lever to drain a small amount of water, and at the same time, link the wires so that the defecation opening shield is opened. On the other hand, when used as a flush toilet, the water accumulated on the entire bowl surface is flushed with the filth by opening the shield at a stretch, and there is nothing in the toilet pipe that causes any resistance. Demonstrate. Further, since there is no difference between the structure of the toilet body and the flush toilet, the problem described below when the simple flush toilet is diverted to a flush toilet can be easily solved.

[0005] Sewage treatment is currently being implemented in sewerage systems in various places, but the simple flush toilet attached to the pumping tub cannot be connected to the sewerage as it is, no matter how good its appearance is.
As disclosed in Japanese Patent Application Laid-Open No. 6-34455 and Japanese Patent Application Laid-Open No. Hei 10-1993, it has been necessary to remove the shield unit below the defecation port in a simple flush toilet and replace it with a flush trap. This was a very difficult task, because the toilet had to be removed once, the dirty parts had to be cleaned, and the trap replaced in the field work had to be connected and fixed so that water would not leak.

In Japanese Patent Application No. 10-63311, the inventor of the present invention uses a small amount of water when using as a simple flush toilet, and when using it as a flush toilet, increases the amount of water on the bowl surface to reduce accumulated water. Invented a toilet bowl that flushes with dirt at a stroke, and that conveys dirt sufficiently for a predetermined distance with about 5 liters of water in a bowl because there is no trap section or constriction section for siphon downstream of the defecation port. In addition, it proposes a device that does not require the use of a toilet bowl as a simple flushing toilet in a pumping tub and the removal of a toilet when connecting to a sewer.

[0007]

First, the toilet shield has a function of arbitrarily operating as a simple flush toilet and a function of storing a large amount of water and flushing it at a stroke as a flush toilet. A flush valve directly connected to the water supply is used to supply only the wash water and to open and close the shield in conjunction with the water supply. Third, when switching from a simple flush toilet to a flush toilet, simply turn the adjusting screw, Use flash valves that do not require replacement. Fourth, install the funnel-shaped defecation tube on the lower surface of the defecation port not in the middle of the bowl surface but in a slightly invisible place. Fifth, the toilet port on the bowl surface should be as low as possible, with a large bowl surface that can hold more than 5 liters of water. Sixth, the use of a flush valve eliminates the low tank and eliminates the need for a toilet room. Seventh, flushing that meets the conditions of adopting a one-piece toilet design that looks wide, and, seventhly, having a mechanism to block odors when installing an overflow line to the sewer required by the Water Supply Law with the use of the flush valve. An object of the present invention is to provide a simple flush toilet that also serves as a toilet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 6 show an embodiment of a simple flush toilet which also serves as a flush toilet according to the present invention. A toilet 1 is made of ceramic or plastics, and a bowl surface 2 is provided. The water outlet 3 is connected to a water source via a water supply pipe 4 and a flash valve 5. Only the washing water is supplied to the bowl surface by the operation lever 6, and the shielding plate is opened and supplied by 6 '. (FIGS. 3 to 6)

The flush valve 5 shown in FIG. 3 can be installed horizontally, and a certain amount of water can be supplied by pushing the push button 7 and the screw at the center of the push button is turned 40 times.
The water volume can be adjusted from 0cc to 8 liters. A recess is formed in the rear side of the pottery of the flush valve 5 and the flush valve 5 is fixed to the pottery toilet. Next, the cover 10 incorporating the operation levers 6 and 6 'is fixed to the pottery surface. The operation levers 6 and 6 'have push pieces 9 and 9', respectively, which are firmly formed integrally, and the operation levers are pivotally supported side by side by a shaft 29 penetrating the cover portion, so that the operation levers can be turned up and down. ing. A spring 8 is provided on the lower surface of the operation lever to always keep the lever in a horizontal position. The operating levers 6 and 6 'have push pieces 9 and 9', respectively, which push the push button 7 of the flash valve halfway from the center to the left and right. Regardless of whether the operating levers 6 and 6 'are pressed at the same time, or whether the operating levers 6 or 6' are pressed separately, the push pieces are activated and the flush valve moves in the direction of water supply. Since the amount of water is adjusted in advance with a water amount adjusting screw, a certain amount of water is supplied by pressing the operation lever. A wire operating portion 18 is fixed to one end of one of the operation levers, for example, 6 ', and the wire 17 connected to the toilet dish is pulled by operating the operation lever 6' to open the toilet dish.

When used as a simple flush toilet, the operation lever 6 'is pushed to open the toilet pan, the waste accumulated on the bowl surface is released, and when the operation lever is released, the toilet pan closes immediately but the fixed amount of 300 to 500 cc is reached. Water supply by the specified flush valve continues, and a certain amount of water accumulates on the bowl surface. When the water is small for the next use, when the operation lever 6 is pressed, only the water flows out again by a predetermined amount and accumulates on the bowl surface. When the flush valve is used as a flush toilet, either of the operation levers may be pushed after the flush valve is adjusted to the flush water amount. That is, when the 6 'is pressed, the wire is activated to open the toilet dish and immediately close the dish, but after that, the washing water accumulates until the magnet balance of the toilet dish is lost, and the toilet dish is automatically opened and discharged. When the operation lever 6 is pressed, water flows in and the amount of water that disturbs the magnet balance is automatically opened and the waste is drained out. Thereafter, when the washing water reaches a predetermined amount of water on the bowl surface, the toilet dish opens naturally and is discharged. Even if 6 and 6 'are pressed at the same time, the operation is the same as when 6' is pressed.

As described above, the toilet plate is opened only when the operation lever 6 'is pressed, so that the wire 17 is pulled out. Inside 18, the operation length required for opening and closing the toilet dish can be freely moved. The toilet bowl opens and closes according to the balance between the amount of water in the bowl surface and the strength of the magnet, so the water level on the bowl surface does not exceed the balance with the magnet, even when using simple flushing or washing. Although an overflow device is not required from the surface, it is assumed that the flush pipe will be clogged when the flush toilet is used. In accordance with the rules of the Water Supply Law, a bowl surface overflow hole 20 is provided 25 mm below the toilet outlet.

Since the overflow hole 20 overflows on the bowl surface, water does not flow except when the defecation pipe is clogged, and there is almost no chance of such overflow. We use as. That is, the synthetic resin hose is dripped from the overflow hole 20 to the watertightly formed ceramic partitioning section 23. In this section, a hole is drilled slightly above the bottom of the rear part, and an inverted U-shaped pipe 22 is attached to connect to an overflow pipe to the outside. In this section 23, water is stored at the bottom, and when the amount of water increases, the inverted U-shaped pipe 2
The water is drained through two. The hose 21 that hangs down from the spout must always be above the stored water level. Further, a hole 24 is formed in the pottery surface facing the rear wall, an exhaust hole is connected to a pipe 25, and the end thereof is connected to an exhaust fan (not shown) installed outdoors. The exhaust fan is operated at all times or when necessary, and discharges the air in the toilet and the toilet to the outside. The overflow pipe 22 is sealed with water, and the odor from the drain pipe is shut off. Only the air sucked from the bowl surface overflow hole 20 is discharged to the outside.

As described above, since water rarely flows from the overflow hole 20 on the bowl surface, the water sealing water 31 evaporates unless water is constantly supplied.
To replenish this water, a small hole 32 is provided on the water discharge side of the flash valve 5 so that an extremely small amount of water is supplied every time the flash valve is operated.

Next, the structure of the toilet port will be described with reference to the drawings.
A funnel-shaped defecation tube 26 that matches the angle of the defecation port is connected so as to cover the lower side of the defecation port 19 that opens obliquely on the bowl surface 2, and the toilet dish 11 is swung around the rotation shaft 12 in the funnel-shaped part. It is movably provided. The toilet pan 11 is a plastic molded product having a pan 13 on one side and a well-known magnetic responsive material such as an iron plate weight 14 embedded in the other on the other side of the rotary shaft 12. The weight 14 can be opened and closed by contacting with and separating from the body.
9 is closed, and the pan 13
, Each having a certain weight to be applied to the water, that is, a weight equal to the weight of the water sealable water amount (several hundred cc). The toilet pan 11 comes into contact with the defecation port 19 via the rubber packing 15 so that the port is tightly sealed with a water seal. Actuating arm 1 worn and protruding
With the opening operation of the interlocking operation lever 6 ′ via the control cable 6 and the control cable 17, it is forcibly opened to open the defecation port 19.

In the funnel-shaped portion 26, the defecation port 1 is provided.
9 of the toilet bowl 11 with the magnetic sensitive material 14 closed
A mounting portion 27 is formed on the side, and a holding portion 28 is arranged below the back of the mounting portion 27 such that a detachable opening portion looks out of the funnel-shaped portion 10. is there. The holding portion 28 is formed so that the magnet 30 can be inserted from the outside of the funnel-shaped portion 26, and the magnet 30 is inserted and fixed to the holding portion 28. The magnet 30 works by attracting the magnetically responsive material balance weight 14 with a magnetic force to increase the closing force of the plate portion 13. The magnetic force of the magnet 30 causes approximately 4 to 5 liters of washing water to flow in the bowl surface 2. In the state where the water is stored, the plate portion 13 is balanced to the closed state, and when the amount becomes larger, the balance is broken, the toilet plate 11 is opened, and the washing water in the bowl surface 2 falls at a stroke to the defecation pipe. The balance is set so that it can be performed. Since the water level at which this balance is lost is set to be several centimeters below the upper edge of the bowl surface 2, when used as a simple flush toilet, the predetermined water level is set when extra water flows into the bowl surface. , The water does not overflow from the upper edge of the toilet even if the bowl surface 2 does not have an overflow port. Also, when used as a flush toilet, the toilet bowl 11 automatically opens when the water level reaches a predetermined level, so that the bowl surface 2 has a capacity of about 7 to 8 liters.
When the amount of water in the inside reaches 5 liters, the balance collapses,
With a single wash, the filth and accumulated water are washed away from the bowl surface 2,
By opening the flush valve, a predetermined amount of water is stored in the bowl surface 2 instead of the water that has flowed away with the waste by the simultaneous operation of the operation lever 6.

Next, a state in which the toilet of the above embodiment is used as a simple flush toilet will be described. When the operation lever 6 'is pressed in both urination and stool, the stool plate opens and the stool in the bowl flows out together with the accumulated water, and the stool plate closes immediately, so that a predetermined amount of water discharged by the flush valve discharges the bowl. Wash the surface and leave it on the bowl surface. Operation lever 6
When the button is pressed, the toilet bowl is not opened, and only the washing water is discharged in a predetermined amount, so that a person who thinks that the amount of water in the bowl surface is low can additionally inject water.

Next, a state in which the toilet of the above embodiment is used as a flush toilet will be described. Normally, the defecation port 19 is closed with the toilet bowl 13 and sealed with 3 to 4 liters of washing water. The flash valve 5 is adjusted to about 5 liters by turning the screw at the center of the push button 7. When the operation lever 6 'is pushed after the stool, the flush valve 5 and the stool 13 are simultaneously opened. The toilet plate 13 is closed as soon as the dirt and the accumulated water flow out, and the remaining water is stored in the bowl surface.
Since the flush valve stops supplying about 5 liters of water, about 4.5 liters of water is stored in the bowl surface 2 for the next use. As another example of use, when the operation lever 6 is pressed, the toilet dish is not opened, and only the washing water is supplied to the bowl surface, so that when the water volume in the bowl reaches about 5 liters, the balance with the magnet force is lost and the stool is lost. The plate 13 automatically opens to discharge waste. In this case, since about half of the washing water is used before flowing out, the stored water in the bowl is about 2.5 to 3 liters, but two can be used.

[0019]

A. Effects of the Invention According to claim 1, the toilet port on the toilet bowl surface is not directly under the toilet as in the conventional simple toilet, but is about 45 inches.
By attaching a toilet bowl with an angle of about °, the sense of discomfort is eliminated as a flush toilet and the toilet bowl is 45 °
The drainage can be efficiently drained to the pipe directly below just by opening it. In addition, by using one flush valve for a flush toilet and a simple flush toilet, the simple flush toilet can be directly connected to the sewer without replacing the water supply equipment. In addition, the use of a flush valve makes it possible to make a freshly designed toilet bowl that does not use a water tank, so that it can be used for a long time as a flush toilet. In addition, when used as a flush toilet, the water stored in the bowl surface flows into the defecation pipe without any resistance, so that the dirt and the water flow together and an excellent conveying force in the sewer is obtained. B. According to claim 2, a flush valve water supply toilet that can be used for both a simple flush toilet and a flush toilet is born. C. According to the third aspect of the present invention, there is provided an exhaust mechanism which satisfies the standards of water supply equipment according to the Water Supply Act and discharges odor in the toilet bowl by using an overflow hole. D. According to the fourth aspect of the present invention, there is no fear of odor leakage because the water sealing for always shutting off the odor from the drain pipe in order to effectively operate the exhaust mechanism is supplied from the flash valve each time the water is used.
