Definitions
- the present invention relates to a drainage guide device for preventing odors and backflow, and more particularly, is provided in a drainage outlet such as a urinal, a sink or a toilet floor to quickly discharge wastewater, and at the same time, odors, sewage or insects flow back through the drainage hole.
- the present invention relates to a drainage guide device for preventing odor and backflow.
- Hygiene legislation stipulates that air must be sealed or sealed with odors or gases from drains.
- Urinals installed on the wall of the bathroom should be able to prevent urine and water from being drained along the drain pipe along the drain pipe and prevent backflow of odor by the remaining water at the top of the drain pipe.
- a conventional urinal has a problem in that a large amount of water is used to clean the urine, so that water resources are depleted, and maintenance costs increase due to the consumption of water.
- a fine odor is continuously generated by the urine contained in the residual water remaining in the drain pipe in order to prevent the reverse flow of the odor.
- a fluid control valve has been disclosed in Korean Patent Laid-Open Publication No. 10-2005-0084278. It includes components with a flat stream of flexible elastomeric material ending at the lower end in the supporting trough-shaped section and a configuration that provides a surface where the ends of the strip can be sealed to allow flow of fluid in only one direction to allow odor or sewage.
- the conventional problem of backflow was solved. However, if it is not restored due to lack of elasticity of the strip, there is a problem that the flow rate of urine is slow to provide a cause of odor and it is difficult to block backflow of odor.
- FIG. 1 is a cross-sectional view showing the use of the conventional toilet bowl
- Figure 2 is a photograph showing the use of the conventional urinal toilet.
- the conventional problem can be solved when the conventional anhydrous toilet 400 is applied to the urinal 500 and used by many users in a short time such as a school or a highway toilet.
- the urinal 500 has the following problems.
- the average urine output from one user is about 300 ml to 400 ml. If there is no additional user after one user uses the urinal 500, the conventional toilet bowl 400 can sufficiently discharge the urine (L) inside the urinal 500. However, when many users continuously use the urinal 500, as shown in FIG. 1, the discharge of the urine toilet 400 does not follow the inflow amount of urine (L) flowing into the urinal 500. There is a problem that the urine L of the preceding user remains inside the 500.
- the subsequent user is reluctant to use the urinal 500 because the state of the urinal 500 is judged to be unsanitary, and even when the urinal 500 is used, the residual urine L remaining inside the urinal 500 is moved to the outside. There is an unsanitary problem popping up.
