Abstract

Water resources can be protected by deodorizers installed in dry urinals. The deodorizer has a membrane-floating sealant that is lighter than urine, allowing urine to flow down through the membrane and out of the drain. Since the sealant continues to deodorize without flushing the urine with water, the S-trap or blood-trap currently in use is unnecessary. The vertical deodorizer consists of a plastic part molded into two parts, completing an integral coaxial dual-chamber bell trap, in which the two parts are assembled in an uneven form. This deodorizer was fitted to fit into the circular opening of the urinal. The sealant is made to be light with a specific gravity of less than 0.9, and it is made of natural pollution-free, which does not harm the environment even if a trace amount can escape. The only maintenance required for this vertical deodorizer is the occasional refilling of the sealant. An alternative, horizontal deodorizer can eliminate or even eliminate this maintenance. The deodorizer of this model has at least one horizontal reentry that allows urine to flow horizontally under the sealant or underneath an upwardly sloped partition. Both parts may flow). This is because the sealing liquid emulsified into the liquid can rise again. The deodorizer complies with all public health, business and residential safety and health laws, and has the advantages of protecting critical water resources, operating more economically and more efficiently than new, most economical flushes, and retrofitting older devices.

The present invention relates to a urinal that does not require water, and more particularly, to a urinal in which an odor removing fluid can replace water.

As the population increases, the increase in water saving and wastewater treatment facilities increases day by day, and the water and toilets used for flushing toilets and urinals are reduced. Interest has increased.

Hygiene legislation requires that gas and odors from the drains of urinals be sealed or sealed. Currently, it uses a well-known method called P-trap (S-shaped) or S-trap (S-shaped) that prevents odor from water remaining in drainage water.

S-trap, a sewage pipe that begins to use disinfectants or deodorants, is disclosed in US Pat. No. 303,822 (D'Heureuse). Toilets using oil as a recirculating drainage medium are disclosed in US Pat. No. 3,829,909 (Rod et al.). The use of deodorizing oil in toilets is carried out by German Patent 121,356 (Bec et al.), US Patent 1,050,290 (Pason; Posson), and US Patent 4,028,747 (Newton).

German patent 72361 (Beetz) of 1891 introduces a latex blocker using a stall urinal (a urinal mounted on a wall without a compartment like a trough). A segmented cylindrical liquid compartment formed a bell trap that allowed urine to descend down through the fluid membrane. The Bites-type odor blocker is designed to be easily disassembled because it is divided into three parts and needs to be cleaned daily and needs maintenance such as coating with internal parts and oil outside the urinal to prevent urine staining.

In Europe, a newer variant of Bites, a coaxial emulsion sealing beltwrap, in German patent 2816 597.1 and Swiss patent 606 646 (trademark SYSTEM-ERNST) is used for the public. Generally, the liquid compartment type deodorizer is installed in the concrete chamber under the floor and fixed. It works like a trough type or staple urinal where water is sprayed down the wall and is no longer recognized by the US Construction Health Law.

Urine of US Pat. No. 4,244,061 (Webster et al.), Which does not require water, fails to remove odors because it does not use oil. Instead, the urinal relies on an inlet called a small plug flow reminiscent of the blood-trap method. This is based on the premise that the urine in the traps in normal use is fresh and free of unpleasant odors.

These urinals, designed in the past, have several drawbacks, especially in the need for maintenance, compared to flushing presses. This has resulted in the widespread use of flushing urinals, especially in times of sufficient water and wastewater treatment facilities. The need for water conservation and mitigation of heavy loads in wastewater treatment facilities, which have been emphasized these days, have motivated the inventors of the hermetic urinal, which has led to the advancement of this technology to the state-of-the-art technology.

It is a first object of this invention to provide a urinal which does not need to be washed off with water using a deodorizer which blocks odors with oil.

Furthermore, it is an object to make it possible to manufacture this urinal deodorizer economically and easily.

Another purpose of this urinal is to eliminate the need for blood traps in the sewers due to the deodorizer.

The aim is to ensure that this deodorizer complies with the public hygiene standard law on urinals in major countries.

Furthermore, it is an object to provide an urinal deodorizer, which is a complete and complete complex, which is replaceable, easy installation, non-degradable, and which requires little or no resupply of the sealing fluid.

The above objects can be achieved by a dual-chamber coaxial oil-sealed urinal odor trap, a current invention which is efficient and requires less maintenance. The coaxial bell-trap consists of two investment molded (molded) plastic parts that can be easily assembled, which are permanently attached by means of projections and grooved recesses and fixtures and ultrasonic welding.

The purpose and features of the present invention, which are considered new developments, are described in detail in the appended patent document. The structure and method of operation of the present invention are referred to the drawings, and it is thought that the explanation with the purpose and advantages will be understood most quickly.

The following description describes the best methods obtained by the inventors in the course of the invention so that any person skilled in the art can make and use the invention. Although the description is limited to providing a urinal with a deodorizing function, in particular without the need for flushing, it will be readily apparent to those skilled in the art that the basic principles of the invention can be modified in various forms.

1A, 1B and 1C are front perspective views, side views, and elevation views of the anhydrous toilet bowl 80 in which the deodorizer 10 of the present invention is installed. The urinal 80 has a urine receiver 81, a drainage passage 82, and an expanded inlet portion 83 for installing a deodorizer. When the deodorizer 10 is pushed into the inlet 83, the circumference fits snugly in any part. The urine receiver 81, the drain passage 82, the inlet portion 83 may be formed in one set or may be assembled in a number using standard piping components. For example, the urine receiver 81 may be made of a suitable material, such as enamel or stainless steel, virtreous china or polyester (plastic) reinforced with fiber glass, and the inlet portion surrounding the deodorizer 10. (83) may use shrinkage adjustable accessories attached to standard ABS sewer pipes.

As can be seen, the deodorizer 10 can be a separate part that can be separated, or it can be fully or partially integrated into the urine receiver 81 and the drain 82 or one portion thereof. In addition, the preferred deodorizer 10 is cylindrical but it can also be easily modified.

There are two general models of deodorizer: vertical 110 and horizontal 210. We will first compare these two models with reference to Figures 2A and 2B. Next, with reference to the following drawings, the configuration of the vertical deodorizer and the two models 210 and 210 'of the horizontal deodorizer, which are alternative models, will be described.

The vertical deodorizer 110 of FIG. 2A and the horizontal deodorizer 210 of FIG. 2B both use the sealing liquid 60 which is lighter in weight than water or urine. It is designed to float on top of the curtain. The preferred sealant 60 is biodegradable so that no traces that may escape may harm the environment. Since the action of the toilet bowl 80 is based on the specific gravity difference between the sealant 60 and the urine 70, and the specific gravity of the urine is generally about 1.0, the lighter the sealant, the better. do. Preferred sealants are emulsions containing aliphatic alcohol containing 9-11 carbons in the chemical chani, with a specific gravity of 0.84 at 68 degrees Fahrenheit (20 degrees Celsius).

Referring to FIG. 2A, the vertical deodorizer 110 has only the downward flow portion 20 and the upward flow portion 50. The downward flow portion 20 includes a sealant 60 floating on the urine 70 already present. This is because when the new urine 71 enters the downward path 20, the urine flows through the sealing liquid 60 and flows with the urine 70 already present to tend to drop the urine. Allowing urine to flow out facilitates the processing and sealing ability of the vertical deodorizer 110, which increases the distance the horizontally the small amount of sealant that can be pushed forward by the incoming urine is horizontal. This is because there are more opportunities to return to the original position before flowing into the outer foot chamber 121a. If the inlet in which the urine enters is located close to the inner partition wall 142, the horizontal appeasement distance is shortened, so that the sealing liquid easily escapes to the outlet 121b.

The insertion part spacing adjuster preferably includes a fastener so that the insert can be easily fitted and securely attached to the body. A good method for a firm attachment is an annular groove and several detents that engage it. The annular groove 126 can be sold on the inside of the outer wall 123 of the body, and the outer outer border 127 of the main body outer wall 123 can be thickened to accommodate the groove.

The fixed key 147 may be made around the spacer 146. Fixing key 147 protruding when the insertion portion 140 is pushed into the main body 120 is inserted into the ring groove 126 to be firmly fixed.

FIG. 3D is an enlarged view of a section cut along the D 'axis from the D axis in FIG. 3C. As shown, the fixing key 147 was made on the spacer 146 to fit into the groove 126 located on the outer wall 123 of the main body. The main body 120, the lid 141 of the insertion part, the spacer 146, and the fixing key 147 are pushed into the groove 126 into which the fixing key of the insertion part 140 is inserted into the body to assemble the deodorizer. Has been standardized to help. Since the lid portion does not need to be removed, a method of permanently attaching the spacer and the groove to the main body by adhesive or ultrasonic welding is preferred. In addition, various fixing methods are possible. For example, instead of the groove 126, a hole is formed around the outer wall 123 to insert the spacer 146 and the fixing key 147.

As shown in FIG. 3A, a sealing liquid 60 through which new urine can pass is floated in a downward portion 121a of the deodorizer. The incoming urine (71) immediately passes down the sealant (not shown), merges with the urine (70) already in place, and overflows into the central drain (122) which leads to the external sewer. The sealant stays in place to act as a deodorant and gas seal, but a small amount of sealant may escape with each use, so re-injection may be necessary after thousands of uses.

FIG. 3B is a cross-sectional view across B 'of FIG. 3A, showing the tubular 142 of the insertion portion acting as an intermediate partition separating the outer wall 123 and the inner wall 124 of the main body. The thickness of this intermediate wall is preferably 1.5 mm.

Again looking at Figures 3A and 3B, the volume of the outwardly downward portion 121a is important, which is temporarily increased in volume by the urine (71) passing through the sealant (60) located therein to deepen the depth. Because. If the volume of the downward portion 121a is made too low, as in the past, the bell-trap deodorizer did, a significant amount of sealant 60 was used inwardly upwards through the bottom of the partition 142 of the insert. It will have to be refilled frequently as it will be pushed back into the drain and eventually released into the drain.

The best type of vertical deodorizer 110 has a sealant capacity of about 320 cc, which is 41.3 cm in diameter because the walls constituting the downward portion 121a are 8 cm in diameter (tubular partition 142) and 10.8 cm (outer wall 123). ^This is because the effective height of the downward portion 121a for accommodating the sealing liquid 60 is 3.5 cm (when the bottom of the tube partition 142 is measured from the bottom end of the tube partition 142 to the ceiling of the main body inner wall 124). . This capacity of 320cc proved to be refilled after thousands of uses and requires no maintenance. Usually the first dose is 3 ounces to 6 ounces (90-180 cc) so that the sealant is only half the total capacity. If more is added, the sealing liquid will be drained to the drain and wasted. The sealant can be used at least 500 times per ounce, so 6 ounces can be used for at least 3000 times. Maintenance and maintenance can be easily monitored by adding a blue pigment to the sealant.

Among the bell-type deodorizers, there was a tendency to be clogged with cigarette material or hair, which would have been saved in the standard of the test of the dry urinal of the US standard on plastic urinals. (American National Standard for Plastic Urinal Fixtures, ANSIZ124.9-1993. Section 7.8 Testing of Waterless Urinals)

However, the current deodorizer is a tubular divider 142 of the (110) insertion portion is separated from the bottom of the main body (125) at a sufficient distance to allow a sufficient flow from the downward (121a) to upward (121b) through the bottom. It is less likely to be blocked. The annular space should be as large as the inner upward (121b) area, ideally at least half the size of the outer downward (121a). For example, when the walls constituting the downward path 121a are 8cm and 10.8cm in diameter, and the walls of the upward path 121b are 4cm and 7.6cm in diameter, the areas thereof are 41.3cm ² and 22.8cm ² , respectively. In the bottom 125, the insertion part tubular partition is 1.6 cm, so that the space for the liquid distribution of the annular space is 32.4 cm ² .

4 shows the shape of 210, which is the best model of the horizontal deodorizer, and 210 'of the lane. As can be seen, the horizontal deodorizers 210 and 210 'models have a lid 241 with an inlet 248. As shown, the lid is preferably inclined radially downward toward the inlet. It is advisable to attach a tightly spaced screen 249 molded into one set (248) at the inlet.

5A and 5B illustrate the internal structure of a preferred horizontal deodorizer 210 with a sickle horizontal retractor 30 drawn in cross-section across 5 to 5 of FIG. As can be seen, the inlet 248 leads to a downward path 20 (see FIG. 2), which directly leads to a horizontal reentrant 30 in which the sealant forms a membrane. This horizontal reentrant consists of a side wall 242 and a bottom 243. As shown in FIG. 5B, when urine 71 enters, it passes through downward passage 20 through sealant 60 to enter liquid 70 already present in oil overhead reentry 30. do. When the emulsified sealant 61 is produced, the recovery site 30 serves to give more opportunity to mix again with the sealant 60 floating on the upper portion. Existing liquid 70 eventually flows horizontally below the horizontal partition 243 to the vertical cylindrical partition 224. The vertical cylindrical partition 224 is provided with an upward path 50 and an drain path 90 outside.

FIG. 6 also shows a horizontal deodorizer 210 with one reentrant 30, in which the model does not use a round cylindrical partition and replaces a square / flat partition 224.

7 is a lane-shaped horizontal deodorizer 210 ', which consists of two reentrants, an oil overhead 30 reentrant and an inclined reentrant 40. This upward slope overhead reentry portion 40 is simple by using the vertical partition 242 'and the inclined horizontal partition 243'. An additional advantage of this model is that if the emulsified sealant flows down the slope, it can rise up along the slope and again merge with the sealant 60 above.

As described above, the horizontal reentrants 30 and 40 also have the advantage of generating various horizontal models using one or several.

As is well illustrated in FIGS. 5 and 7, the horizontal deodorizers 210 and 210'type oil overhead reentrants 30 and 30 'have a seal pushed between the sealant surface and the inclined covers 241 and 241'. There is an empty space 35, 35 'where the fluid can be transported. The space is designed to serve as a safe harbor so that the sealant (60) can be preserved in case large amounts of water are sprinkled with buckets or hoses at once. Normal deodorizers have no choice but to lose the sealant. In this case, however, the sealing liquid floats on the incoming liquid 71 and moves toward the empty spaces 35 and 35 'so that only the incoming liquid flows safely without consuming the sealing liquid.

Experts will recognize that in addition to the preferred forms described above, various modifications are possible without departing from the scope and spirit of the invention. It is therefore noted that within the scope of the appended claims, they do not have to be implemented as described above.
