Definitions

  • the present invention relates, in general, to a backflow prevention urinal and, more particularly, to a backflow prevention urinal using a control ball, which is capable of rapidly discharging urine and preventing the backflow of an odor, owing to the control ball.
  • Urinals are installed in public toilets. There are many problems with urinals because many people frequently use them.
  • the drain of the urinal is provided with a waste trap where water stays, thus preventing odors from flowing backwards.
  • urinals which do not use water are commercially available. Most of the urinals use chemicals to neutralize the main component of urine, ammonia. However, the urinals are problematic in that the chemicals must be periodically replaced with new ones, so that it is inconvenient to use.
  • the conventional urinal drains have a drawback in that they have a complicated structure or are inconvenient to maintain.
  • an object of the present invention is to provide a backflow prevention urinal using a control ball, which has a simple structure, allows urine or impurities to be rapidly discharged, and effectively prevents odors from flowing backwards owing to the control ball, thus forming a pleasant appearance and being sanitary.
  • the present invention provides a backflow prevention urinal having a urine receiver and a drain provided in a lower portion of the urine receiver to discharge urine
  • the drain includes a housing connected to a waste pipe, and having a shape of a container; a main body provided in the housing and including an inlet provided on an upper portion in the housing so that the urine is introduced into the inlet, a passage provided under the inlet, bored horizontally, and having a circular shape, a slope communicating with the passage and inclined downwards towards the passage, and an outlet provided in the slope and discharging the urine passing through the passage; and a control ball having a spherical shape and received in the slope, the control ball moving downwards because of gravity to close the passage, or opening the passage by pressure of the urine flowing into the inlet.
  • the passage may be located at a center of the main body, and the slope may be inclined in such a way that a surface thereof is rounded into a curved shape, a lowermost portion of the slope communicating with the passage.
  • a packing may be provided on an edge of the passage and be made of an elastic material to allow the control ball to come into close contact with the passage.
  • a cap may be hinged to a lower end of the outlet to open or close the outlet, with a weight being provided at a predetermined position of the cap to keep the cap closed.
  • a trap may be provided on a lower end of the outlet, the trap having a shape of an empty bag and made of a latex material.
  • a backflow prevention urinal is advantageous in that it has a simple structure, allows a mechanical operation to rapidly discharge urine or impurities, and reliably prevents odors from flowing backwards.
  • a backflow prevention urinal is advantageous in that either of a cap having a weight or a trap made of a latex material is additionally provided to the urinal, thus providing a failsafe against odors flowing backwards.

  • FIG. 2 is a cutaway perspective view showing the internal structure of a backflow prevention urinal using a control ball according to an embodiment of the present invention
  • FIG. 3 is a cutaway perspective view showing the internal structure of a backflow prevention urinal using a control ball according to another embodiment of the present invention.
  • FIG. 4 is a cutaway perspective view illustrating the operation of the control ball of the present invention for preventing the backflow of odors.
  • FIG. 1 is a perspective view showing a general urinal
  • FIG. 2 is a cutaway perspective view showing the internal structure of a backflow prevention urinal using a control ball according to an embodiment of the present invention.
  • the present invention is directed to the urinal having a urine receiver 100 and a drain 200, and has technical characteristics in the drain 200.
  • the drain 200 may mainly include a housing 220, a main body 240, and a control ball 260.
  • the housing 220 is provided on the lower portion of the urine receiver 100, and is connected to an underground waste pipe (not shown) for discharging the urine or wash water.
  • the housing 220 may generally have a cylindrical shape, accommodates the main body 240 and the control ball 260 therein, and may be made of a resin material.
  • a plurality of holes is formed in the upper surface of the housing 220 to allow urine to pass through the housing 220.
  • the main body 240 is provided in the housing 220 to discharge urine and mechanically prevent odors from flowing backwards, and may mainly include an inlet 242, a passage 244, a slope 246, and an outlet 248.
  • the inlet 242 is shaped to be depressed downwards from the upper surface of the housing 220. Urine is directly introduced into the inlet 242, and in addition, the inlet 242 guides the introduced urine downwards.
  • the inlet 242 may have a variety of shapes.
  • the inlet 242 may have the shape of a cylindrical depression, a through hole, or a conical depression which is tapered in a direction from an upper position to a lower position. Further, as shown in FIG. 2, the inlet 242 may roughly have the shape of a spiral path.
  • the passage 244 comprises a circular hole which is bored horizontally to communicate with the lower portion of the inlet 242.
  • the vertical section of the passage 244 may be formed to be upright or inclined at a predetermined angle.
  • a packing (not shown) made of an elastic material may be attached to the edge of the passage 244. The reason for this is because the packing puts the control ball 260 in close contact with the passage 244, thus increasing the sealing effect.
  • the packing may usually use soft rubber.
  • the passage 244 is positioned at the center of the main body 240 and communicates with the slope 246.
  • the slope 246 has a space which is inclined and curved at its bottom, and receives the control ball 260 which will be described below in detail.
  • the slope 246 may be inclined upwards from a portion of the passage 244 in the shape of a plane.
  • the slope 246 has the shape of an inverted cone or hemisphere so that its surface is rounded into a curved shape. This allows gravity to return the control ball 260 to the center even if the control ball 260 received in the slope 246 is shaken by external force and is located at some other position.
  • the aforesaid passage 244 is positioned at the center of the housing 220, the slope 246 is formed to be right adjacent to the passage 244, and the passage 244 communicates with the lowermost portion of the slope 246, thus precisely closing and sealing the passage 244 when the control ball 260 returns to the original position thereof.
  • the outlet 248 is formed in the bottom of the slope 246, and has the shape of a hole which is bored vertically, thus discharging downwards the urine that has passed through the passage 244 and reached the slope 246.
  • the outlet 248 may have a variety of shapes, including a circular shape and a rectangular shape, but has a size permitting the control ball 260 to move along the slope 246 without being removed therefrom.
  • control ball 260 has the shape of a spherical ball, is received in the slope 246, and is moved downwards by gravity to close the passage 244. Further, the weight of the control ball 260 is set such that the control ball 260 is in close contact with the passage 244 when pressed by the pressure of gas which flows backwards.
  • the control ball 260 may be a solid ball which is made of a light material or a ball which is hollow. That is, the control ball 260 may be a solid ball made of a material such as resin or hollow ball like a ping-pong ball.
  • the control ball 260 is larger than the diameter of the passage 244 and the outlet 248.
  • a cap 300 may be further provided on the lower portion of the housing 220 to provide a failsafe against odors flowing backwards, thus improving the backflow prevention effect.
  • the cap 300 may have a shape similar to that of a stopper, and is coupled to the lower end of the outlet 248 to open or close the outlet 248.
  • the cap 300 may have a shape corresponding to the sectional shape of the outlet 248, and is hinged to a side of the outlet 248. Thus, the cap 300 may be opened or closed by external force.
  • a weight 320 is attached to a predetermined portion of the cap 300, and has a predetermined weight.
  • the weight 320 is comparatively heavier than the cap 300.
  • the cap 300 is moved upwards about a hinged joint by the weight 320, thus closing the outlet 248. If urine reaches the cap 300, the cap 300 is opened by the weight of the urine.
  • FIG. 3 is a cutaway perspective view showing the internal structure of a backflow prevention urinal using a control ball according to another embodiment of the present invention.
  • a trap 400 having the shape of an empty bag may be further provided on the outlet 248.
  • the trap 400 is coupled to the lower end of the outlet 248.
  • the trap 400 may have the shape of the empty bag, and may be made of thin vinyl, preferably, a latex material.
  • the latex is crude rubber and is used for a variety of purposes.
  • the latex is shaped into a bag having the thickness of about 0.1mm, so that it is opened by the pressure of urine which falls from an upper position to allow the urine to pass therethrough, but is closed because of water remaining on the surface of the latex after the urine has all completely passed through the latex. Thus, gas which flows backwards does not pass through the trap 400.
  • FIG. 4 is a cutaway perspective view illustrating the operation of the control ball of the present invention for preventing the backflow of odors.
  • the urine which has passed through the passage 244 flows to the slope 246 and is discharged downwards through the outlet 248.
  • the control ball 260 may float on the urine which remains on the slope 246.
  • the urine discharged through the outlet 248 accumulates in the cap 300 which closes the outlet 248.
  • the cap 300 moves in a manner similar to that of a seesaw and thus opens downwards.
  • the urine is continuously discharged to the waste pipe.
  • control ball 260 is normally located at the lowermost position of the slope 246 because of gravity, thus closing the passage 244. If gas flows back from the outlet 248 to the slope 246, the control ball 260 is pressed by the pressure of the gas, and thus comes into closer contact with the passage 244, thus preventing the inflow of the gas.
  • the cap 300 is normally kept closed by the weight 320, thus primarily blocking the gas which flows backwards, therefore preventing the gas from flowing through the outlet 248 to the slope 246. However, some gas flowing back to the slope 246 is secondarily blocked by the control ball 260, thus reliably preventing the backflow of odors.
  • the trap 400 has the same effect as the cap 300.
  • the urinal may further include a control unit.
  • control unit When a sensor senses users and detects the number of times users have urinated, the control unit performs control to wash a flushing bowl using water according to the number of urinations.
  • control unit may control a time to wash the flushing bowl using water according to a predetermined period.
  • Such a control unit always keeps the flushing bowl clean, in addition to uniformly maintaining the flushing bowl.
  • control unit senses the cumulative number of times users have urinated, thus informing a user when cartridge is supposed to be replaced. Thereby, even if the user does not check the replacement time of the cartridge after the predetermined interval of time, the control unit informs the user of the replacement time, thus preventing the user from missing the replacement time of the cartridge.
