Description

  The present invention relates to a urine separation toilet that separates urine and urine, and further relates to a toilet that collects wash water that has washed the toilet bowl surface and reuses it as circulating wash water.

  The present inventors have so far disclosed many techniques related to a simple flush toilet that shuts the toilet outlet using a toilet bowl, has a deodorizing function, and cleans the toilet bowl surface with a small amount of water. In addition, we have made efforts to develop toilets that go beyond simple flush toilets by shutting off the discharge port with a toilet bowl at the toilet outlet and washing the toilet bowl surface with the same amount of flush water as a flush toilet. In the patent document 1, the present inventor has disclosed a system for removing urine, which is water that becomes an obstacle when composting compost or incineration, and circulatingly washing a toilet with sufficient water. . Furthermore, in Patent Document 2, the lower processing device is considered to be connected to a stool or septic tank instead of a composting or incineration processing device, so that the urine is stored together with moisture and left for decomposition or pumping, and the toilet bowl surface is filled with urine. Disclosed is a system for automatic circulation cleaning with no wash water. However, in this method, since the toilet flushing water recovery channel provided on the side of the defecation pipe is used for the recovery of the flushing water, the disadvantage associated therewith is corrected and the toilet having the flushing water recovery channel disclosed in the proposed document 3 is used. Developed. That is, after dropping the urine and a small amount of washing water downward through a freely-operated toilet bowl provided at the defecation port, the toilet bowl is locked and a large amount of washing water is provided around the toilet bowl cylindrical portion A toilet that is collected from a circumferential slit.

At the time of the development of Patent Document 1, the purpose was to remove water for compost toilets that dislike excess water and for transporting helicopters, but now the urine is separated and nitrate nitrogen is removed from the urine by various means. In order to reduce the amount of nitrogen in the treatment tank and reduce the BOD value by using stool-derived BOD in the treatment tank as a carbon source, the nitrate nitroso is converted into urine for technical development. Separation is required.
The toilet of Patent Document 1 was provided with a slit in the toilet bowl surface to collect urine when using boys' stool and girls using urine. Since there is a composting tank at the bottom and a toilet tank that only wants solids is placed, the toilet bowl in the toilet bowl is open during the toilet, so you must collect urine from the slit did not become. Moreover, the shape of the slit on the toilet bowl surface gives the user a sense of incongruity and sometimes has the disadvantage that paper is caught. In order to solve such a problem, the toilet structure having a urine separation function was applied to the flush water toilet according to the proposed literature 3, and the urine was separated using a toilet having a shape that is easier to use.

The problem to be solved is to first stop the slit on the toilet bowl surface, make it a shape close to a flush toilet, and do not give the user a sense of incongruity, and secondly it does not fluctuate in the flow of a small amount of water like a urine, The weight of stool and wash water that flows with it has a stool with a movable weight balance, and a small amount of water such as urine does not drop into the lower stool. The third purpose is to provide a urine separation toilet that separates a small amount of water, and thirdly, a urine separation toilet that separates as much urine as possible by adding a device to the toilet bowl.

The present invention is characterized by the following configuration in order to achieve the above object.
1. An annular water intake is formed between the toilet drop at the lower part of the bowl surface where wash water can be supplied from the water supply device and the upper end of the stool-like defecation pipe on the outer periphery of the toilet drop, and the outer periphery of the annular intake A drainage pipe extending from the continuous annular water collecting portion, and a shield is provided in the defecation pipe so as to be openable and closable below the upper end mouth portion of the defecation pipe. A locking element that can be stopped at a closed position with respect to the part is provided. The toilet bowl has a toilet bowl in which the balance strength of the shielding body in the form of a balance toilet bowl is set so that it does not open even if a small amount of water flows for a certain period of time.
2. In order to collect as much urine as possible, the part corresponding to the toilet drop of the toilet bowl part is raised, and the structure has a type of toilet bowl that collects water only in the outer peripheral part of the toilet bowl part.
3. A pipe with a small-diameter inlet that drops a small amount of weak liquid flow is directed downwardly or branched at a certain angle to the toilet drain pipe line, and the water flow exceeds a certain level. The water is characterized by having a branch portion set to flow over the branch pipe.

The lower stool opening part of the bowl surface in the present invention may be the lower end mouth part of the bowl surface, or may be the lower end mouth part of the guide tube suspended from the lower end mouth part. The annular water intake portion may be a gap space for passing water through 360 degrees, and a rib for holding the gap space may be provided in part. The positional relationship between the stool outlet and the upper end of the defecation pipe forming the annular intake portion is basically the inner and outer positional relationship where the outer upper stool is opposed to the inner stool outlet. However, the upper and lower positional relationship between the stool outlet and the upper end of the defecation pipe may be the same height or different heights. What is necessary is just to become the positional relationship which does not enter a water collection part. Further, the clearance between the annular water intakes is preferably narrow within a range where washing water and urine can pass through without stagnation, which is effective in preventing the entry of foreign substances and the like. The locking element is not limited as long as it can stop the shield in the closed position. For example, a solenoid that can be locked with a forward / backward pin for a balance-type shield that opens when a certain weight or more is applied, such as manure, but does not open at a water-sealed weight to prevent urine and odor. An electromagnet body that can lock the above-described balance type shielding body with a magnetic force, a driving and locking element that can forcibly lock the shielding body in an open / close operation and a closed position, and the like. The strength of the balance toilet bowl of the shield is determined by experiment, and the balance toilet bowl does not open with the amount of urine flowing, the urine flows out of the toilet from the annular intake, and is separated at the branch part provided in the drain pipe Collected separately. The urine flow rate is set to a flow rate of about 250 cc to 400 cc between 15 seconds and 20 seconds, and the toilet stool is created so that the toilet stool rotates when the flow rate is higher than the stool weight.

  The toilet bowl lock is always open and the dish can rotate freely. It does not rotate with a small amount of water according to the urine, the toilet bowl rotates freely for stool and toilet flushing water that flows 200 to 300 cc in a few seconds, and filth drops downward. After the urine is separated by a branch line provided in the pipeline, leave about 200 to 300 cc of wash water with a time difference of about 5 to 6 seconds, drop that part into the toilet tank, and then a time difference of about 5 to 6 seconds. Since the microcomputer is set so that the circulating wash water flows after the toilet bowl is locked, the circulating wash water does not fall into the toilet bowl. A method of sensing with infrared rays when the user enters the stool area as in the case of Model Document 3, and washing water may flow when leaving the stool area.

A Since the annular water intake portion opens in any direction of 360 degrees according to claim 1, even if part of the annular water intake is jammed, urine and washing water can be recovered from other locations. Therefore, it is not necessary to attach a slit or the like for separating urine to the bowl surface, and the commercial value is not impaired.
B According to claim 2, a smaller amount of urine is left than the flat-plate-shaped toilet bowl, and the urine is replaced with washing water after a few seconds, but the amount of urine falling into the toilet bowl is extremely small, and much urine is separated. I can do it.
C According to claim 3, only urine with weak water power is separated by a branch passage and collected in a urine tank by another pipe. Compared with the method of placing an electromagnetic valve on the branch path in Patent Document 1, the cost is low and there are few failures.

1 to 6 exemplify an embodiment of the toilet device of the present invention, and a guide tube 3 is suspended from a lower end mouth 2b of a bowl surface 2a in a toilet 2 installed on a floor 1a of a housing 1. An annular water intake 5 is formed between the stool outlet 3a at the lower end of the guide pipe 3 and the upper end 4a of the stool-like defecation pipe 4 on the outer periphery of the stool outlet 3a. The annular water collecting portion 5 is formed by making the inner diameter c of the tubular member 4c larger than the inner diameter b of the feces dropping port 3a, and having an upper and lower difference d that is higher at the upper end port portion 4a than the feces dropping port portion 3a. The falling manure does not easily come into contact with the inner surface of the tubular member 4 c and does not flow into the annular water intake 5.
An annular water collecting portion 6 is provided around the outer periphery of the annular water intake portion 5 so as to communicate therewith, and a drain pipe 7 is extended to the annular water collecting portion 6 formed of the annular space so that the annular water collecting portion 6 has an annular shape. A washing water recovery path that reaches the drain pipe 7 through the water intake section 5 and the annular water collection section 6 is formed.
A hard rubber cylinder member 4c is engaged with the engaging protrusion 4b on the inner surface of the lower side of the upper end opening 4a of the defecation tube 4 and attached to the inner surface of the defecation pipe 4, and the toilet passage opening 4d at the lower end of the cylinder member 4c. A shield 8 is provided on a support shaft 9 so that it can be opened and closed.

The shield 8 has a base end by pivotally supporting the toilet bowl 8a in a dish-like metal or plastic toilet bowl 8a capable of sealing the toilet passage 4d with a small amount of water, and the support 8b at the distal end. The support 8d is provided with a magnetically sensitive member weight 8c at the center, and the support 8b pivotally supports the toilet bowl 8a so that the toilet bowl 8a contacts the toilet passage 4d. And can be closed. The weight 8c has a weight of water seal water for removing odor while the toilet bowl 8a integrated with the support 8d swings and opens around the support shaft 9 when a certain weight or more such as urine is loaded. The balance is such that it does not open at the weight level but stops at the closed position. A balance of about 200 to 400 cc of water is maintained between 10 and 15 seconds.
An electromagnet body 10 is disposed on the lower surface of the seating portion 4e of the defecation tube 4 on which the weight portion 8c rides in the shield body 8 in the closed position, and is made of a magnetically sensitive member by a magnetic force generated in an ON state when the electromagnet body 10 is energized. The weight 8c is attracted so that the toilet bowl 8a can be stopped and locked at the closed position of the toilet passage 4d, and in the OFF state, the lock is released and the toilet bowl 8a receives a load such as manure. It can be opened.

The toilet bowl is washed as follows.
When you press the switch that is a little far from the toilet after leaving the stool, a microcomputer program is built in due to the time difference and the wash water flows 5 to 6 seconds after the stool and the toilet bowl surface is washed and dropped into the toilet tub. Immediately thereafter, the bowl surface 2a is supplied with a sufficient amount of washing water from the spout 11 while the toilet bowl 8 is locked. Further, as described in the practical document 3, it is possible to cope with a system that automatically detects pre-cleaning, toilet cleaning, and circulation cleaning by detecting that a user has entered a certain area.

  Next, a toilet bowl for collecting as much urine as possible will be described. If the entire toilet bowl is concave, the amount of water that accumulates there is also large. Make the center of the dish a protruding flat plate and do not stand the edge of the dish. The amount of urine that falls downward is reduced as much as possible by making the water reservoir 32 while being suppressed by the soft synthetic resin packing 31. After cleaning the bowl surface, the circulating cleaning water accumulates and seals. If the goodness of the packing is good, there is a deodorizing effect even without water seal water. Since 300 cc of washing water before the lock function is not activated after the stool flows for 1 to 2 seconds, the dish is washed with the running water and the water falls downward.

  A branch path 33 is provided vertically to the drain pipe at an arbitrary position of the drain pipe. The diameter of the bifurcation is reduced, and only urine with weak water flow passes through this route, and a large amount of water with strong water jumps over this pipe and flows through the drainage pipe. The attachment position of the branch path may be inside the toilet bowl or may be considerably downstream of the drain pipe.

  Next, the state of use will be described. When not in use, the electromagnet body 10 and the water supply pump 19 do not rotate continuously, the shield 8 or 38 stops to be openable in the closed position, and the toilet passage 4d is sealed with water. The toilet bowl odor does not leak indoors. When both men and women use urine, the balance of the weight is set so that the toilet bowl does not open with the water force and water volume during urination, so the urine flows into the annular water collecting part 6 through the annular water intake part 5. Since the flow of urine is weak, it enters the urine recovery path through a small hole in the branch portion 33 provided in the pipe and is stored in the urine tank 35 outside. When using a stool, the stool opens with its weight and the stool falls into the toilet bowl. The washing water inflow operation is controlled by a microcomputer so that it flows in time difference when using a hand button. First, approximately 200-300cc of washing water flows without the toilet bowl locked, and the bowl surface is washed away. To drop. Next, the toilet bowl is locked, and about 2 liters to 5 liters of pre-purified water flows, but this enters from the annular water intake part and flows through the annular water collecting part to the drain pipe. Since this flow is large in volume and strong in water, only a very small amount flows over the urine collection hole at the branch and enters the urine collection channel.

  The hand push button is instructed to be operated after the end of the stool, and it is desirable to be away from the toilet as much as possible. However, there is a time difference in the inflow of washing water in the microcomputer setting, and the stool push button is operated. After 4 to 5 seconds, the washing that falls into the first washing stool flows, and after 4 to 5 seconds, the circulating washing water collected from the annular water intake portion flows, so that the urine is completely separated. Even if the method disclosed in the practical document 3 detects that the user has entered the toilet area with infrared rays and then uses a fully automatic washing method, the operation is the same and the urine can be separated.
