## Background
RELATED APPLICATIONS
This application is a 371 application of International Application No. PCT/KR2008/006377, filed Oct. 29, 2008, which in turn claims priority from Korean Patent Application No. 10-2007-0110783, filed Nov. 1, 2007, both of which are incorporated herein by reference in their entireties.
TECHNICAL FIELD
The present invention relates to a toilet stool for odor removal, and more particularly, to an improved odor removal toilet stool using a preserving energy as a power source, capable of removing bad smell air and preventing its back flow in which the cleaning water (supplying water) stored in a water storage tank is supplied at two stages such as an initial standby water level and later kill water level, wherein during supplying water to the kill water level, air transference method using hydrodynamic operation occurred from a high speed injection with a injection nozzle is used without electric energy.
BACKGROUND ART
Generally, a toilet stool refers to a western style flush toilet on which a person may astride and excrete wherein when excreting by using the toilet stool, the feces and urine excreted from the eliminatory organ inside body of a user make promptly bad smell air.
In more detail, when a small amount of the excrement such as feces and urine being excreted by the user who sits on a toilet seat drops into a fresh water in a pre-determined space inside a toilet body, and most of bad smell air is made during this extreme instant moment of dropping, which makes the surrounding persons unpleasant.
Currently various types of the western style toilet stools with a odor removal function have been studied, developed and sold in a market to solve overall problems including the aforementioned unpleasant feeling. Among these disclosures, Korean Utility Model registration No. 20-0169267 disclosed a odor removal configuration for a toilet stool in which the bad smell air is absorbed and discharged with an impeller (F) using a rotation force obtained through a suction motor (M) which is driven using external power source. Up until now, this type of technology has been adopted typically for removing bad smell air.
However, according to the prior art, a separate power source such as electric energy for driving the suction motor (M) and impeller (F) has to be necessary and further the mechanical noise produced in operating these devices exceeds to reference values such as 60 dB (night) to 80 dB (daytime), which is noted on “regulation reference of daily life noise and vibration” in Table 8 of enforcement regulation (related to the same act 21(2)) of the noise and vibration regulation act prescribed on the Ministry of Environment decree No. 247 (fully revised on Sep. 13, 2007). Meanwhile, the suction motor making a roaring sound often stimulates user's nerves and makes him/her troubled regardless of the aforementioned regulation reference of daily life noise.
Additionally, taking into consideration of the characteristic configuration of the western style toilet, the inner diameter of a discharging tube for absorbing/discharging bad smell air is much limitative, and further a centrifugal fan manufactured for an absorption, instead of general air ventilation such as a axial flow type fan, is properly adopted, however, there has arisen a problem in that a wide space is needed for installing the suction motor (M) a rotation per minute (rpm) of which becomes higher to perform efficiently the absorption, and the impeller (F) a diameter of which is enlarged to perform efficiently the discharge, causing manufacturing cost expensive and further making the life noise reference greater.

Therefore, the fill valve can be closed by connecting simply the pulling wire 26 to one side of the external end of the second floating unit 212.
The fluid operation tube 3, as shown in FIGS. 7 and 8, is provided for absorbing forcibly the bad smell air within the stool body 1-1 with an air transfer method which uses an internal pressure reduction phenomenon induced from a fine and high speed injection of the supplementary water through the injection nozzle 25, without a separate external power source. Here, the fluid operation tube 3 is shaped as “” character and its the lower end of a straight tube in a vertical direction is connected in communication to the opening of the upper end of the over flow tube 1-213, and a cut and curve part thereof is formed as a spherical shape having a relative greater volume than that of the straight tube so that sufficient gas can be supplied and flowed. Furthermore, a horizontal straight tube is slanted at a predetermined angle (θ) for a tip end thereof to be downward so that a speed discharging flow of water drops consisting of fine particles can be induced.
The bad smell air discharging means 4, as shown in FIGS. 7, 9 and 10, is provided for that the fluid injected through the fluid operation tube 3 is separated naturally into top and bottom parts based on specific gravities of the fine particles at the same time when being injected, and light gas rises in a form of rotation air current and then is discharged completely through an induction procedure of free fall, and when after completing the supply of the supplementary water, the bad smell air is prevented from being flowed back through a water film valve that is produced with water drops discharged together with the gas. Here, the bad smell air discharging means 4 is comprised of a induction drum 41 adapted such that the injected fluid rises as a rotation air current and at the same time water drops of larger particles (liquid) fall downward and then the cleaning water within the storage space 1-2a is supplemented for a predetermined time period, thereby separating naturally the fluid, and a barrel 42 adapted such that the bad smell air and the water drops of fine particles risen through the induction drum 41 are received therein and leaded to the trap tube 1-12, thereby preventing an external discharge of the bad smell air and a flow back thereof.
The induction drum 41 is configured as a cylinder such that the tip end of the fluid operation tube 3 is in communication with deflectively one external peripheral part of the induction drum, and the upper end thereof is covered to be rested over the upper end of the barrel 42, and the lower end thereof is opened. Additionally, the lower end of the induction drum 41 is not fully contacted with the bottom surface of the tank part 1-21 and a predetermined space is formed therebetween, and thus the cleaning water within the storage space 1-2a fills and inputs into the induction drum, while the water drops of greater particles among the fluid injected through the fluid operation tube 3 is used as a supplementary water to increase water level of the cleaning water.
The barrel 42 is comprised of a fall induction tube 421 for receiving and falling down the fluid risen by the induction drum 41, and a discharge induction tube 422 on upper end of which a back-flow prevention plate 422-1 is assembled. Here, the back-flow prevention plate creates the water film valve with water drops in order to discharge the fluid passing through the fall induction tube 421 and prevent injected bad smell air (gas) from being back-flowed.
Additionally, the fall induction tube 421 is comprised of: a funnel part 421a on the upper end thereof on which a plurality of passing holes 421a-1 for allowing the rising fluid in a form of a rotation air current to be passed is formed at each same distances, and which is configured in a form of a upper wide and lower narrow for receiving the passed water drops and guiding them efficiently into a center thereof; a induction part 421b on the middle end thereof which has a relative narrower diameter than that of the funnel part 421a for falling down efficiently the bad smell air and the water drops and is configured in a straight tube form, and a first enlarged part 421c on the remote end thereof a discharge sectional area of which is enlarged increasingly downward from the lower end of the induction part 421b in order to settle the unsmooth fluid discharge operation which is interrupted with the back-flow prevention plate 422-1.
Meanwhile, in an operation of the fall induction tube 421, when the supplementary water supplied additionally exceeds to a full water level, the overflowed cleaning water is flowed through the passing holes 421a-1 and the barrel 42, and passes the external discharge tube 1-13 and the trap tube 1-12, and is discharged into the water purifier tank. Accordingly, the fall induction tube can replaces the functions of a typical overflow tube.
Here, the discharge induction tube 422 is provided on the upper end with a second enlarged part 422a which has the same diameter as the lower part of the first enlarged part 421c to be connected thereto, and has relatively smaller diameter at the lower end thereof in order to be communicated to the external discharge tube 1-13.
Referring to the back flow prevention plate 422-1, it is provided through the second enlarged part 422a of the discharge induction tube 422 as one piece so that when the supply of the supplementary water by the suction power means 2 is ended, the water film valve is to be formed with the flowing down water drops which has been already made on the inner wall of the induction part 421b or the first enlarged part 421c, thereby preventing the bad smell air from being back-flowed. Furthermore, the back flow prevention plate 422-1 is comprised of: a plurality of track ends 422-11 and cut and curve ends 422-12 which is configured as a circular stepwise rising toward external side based from a center thereof so that the water drops can be distributed evenly overall areas at the instant moment of the gas flow being dropped; and a drilled hole tube 422-13 is formed as a straight tube of a predetermined diameter and length, and disposed downward from the respective surfaces of the track ends 422-11, and thus allows the fluid to be passed through but the fallen (or flowed) water drops to be stayed inside by their attraction operation during a movement along the track ends 422-11 and the cut and curve ends 422-12, thereby forming the water film valve.
Here, not-described reference numeral, 1-1b designates a through-flow hole a plurality of which are disposed on the edges of the excrement space to be communicated to the supply tube, and which is provided for draining the cleaning water that pushes the excrement to the trap tube through the supply tube in the stool body, or absorbing forcibly the bad smell air. In addition, the reference numeral, 1-21a designates a drainage hole for allowing the cleaning water within the storage space of the tank part to be inputted into the supply tube, and 1-21b designates a discharge hole for discharging the fluid that is flowing down through the barrel, through the external discharge tube.
The operations of the odor removal toilet stool using a preserving energy as a power source according to the present invention will be described in detail as follows.
Firstly, as shown in FIG. 12, an initial standby water level before using it is set such that the height of the first floating unit 1-212c for regulating the water level that is assembled on the upper side of the first water level regulator 1-212d of the first balltap 1-212 which is basically installed within the water storage tank 1-2, is lowered to the height of about 1⁄2 or 2⁄3 of the full water level within the storage space 1-2a. Subsequently, the cleaning water supply from the standby water level to a remainder of full water level is performed with the supplementary water which is additionally supplied at a predetermined time period by opening the fill valve of the second balltap 21 with an operation of the push button 24 by a user when excreting.
Here, the standby water level is set to the height possible of a minimum siphon operation and thus when rapid excrement such as urine or vomiting is performed, only the amount of the cleaning water at the standby water level is enough to discharge the excrement without the additionally supplied supplementary water through an operation of the push button 24, thereby obtaining a first saving water effect.
Meanwhile, when the supplementary water is not able to be supplied additionally due to mis-operations of the push button 24 or the second balltap 21, the first floating unit 1-212c is raised to the height of the full water level to solve simply the above problem.
Continuously, as shown in FIGS. 3 to 6, the suction power means 2, the fluid operation tube 3, and the bad smell air discharge means 4 are all assembled and installed within the water storage tank 1-2, thereby completing a configuration of the odor removal toilet stool A according to the present invention.
At this time, the second balltap 1-212 of the suction power means 2 may be connected to the water pipe installed on one wall surface of a bathroom by using a separate hose and thus makes the additional supply of the supplementary water possible. Additionally, a user seats on the stool seat 1-31 of the seat 1-3 and then pushes the push button 24 to open the second balltap 21 and thus the supplementary water is inputted through the third vertical tube 211 and the second water supply hose 22. Here, the cleaning water is fine-injected at a high speed into the fluid operation tube 3 with the injection nozzle 25 and then passes through the induction drum 41, and supplied additionally to within the storage space 1-2a at a predetermined time period, to raise the water level of the cleaning water so that the cleaning water is stored up to the full water level defined by the second floating unit 212 and the second water level regulator 213 of the second balltap 21, and thus the discharging process of the excrement into the water purifier tank when completing the excrement is performed without difficulties.
Hereinafter, all steps and procedures for creating disguising sound almost similar to a natural sound to offset an excrement sound, together with a removal of the bad smell air made when excreting and a prevention of its back flow, will be described, referring to the accompanying drawings.
Firstly, as shown in FIGS. 11, 12 and 15, a user seats on the stool seat 1-31 of the seat 1-3 assembled to the stool body 1-1 and at the same time he/she pushes the push button 24, as shown in FIG. 13, for supplying additionally the supplementary water for discharging efficiently the excrement, to loose the pulling wire 26, thereby making the second floating unit 212 and the second water level regulator 213 of the second balltap 21 leaned, causing the fill valve of the second balltap 21 to be opened.
As a result, the cleaning water stored up to the standby water level is raised by the supplementary water which is supplied through the third vertical tube 211 of the second balltap 21 and the second water supply hose 22, and further the disguising sound (etiquette bell) is produced by a water supply sound of the supplementary water which is fine-injected into the fluid operation tube 3 through the injection nozzle 25 at a high speed and a water supply pressure in order to offset a physiological sound produced when excreting. Accordingly, other persons do not notice his/her excrement behavior and further water saving effect from a prevention of water pouring is obtained.
Meanwhile, when the supplementary water is fine-injected at a high speed into the fluid operation tube 3 through the injection nozzle 25, the water particles with a relative lower density are rapidly injected into the induction drum 41 along the inner wall of the fluid operation tube 3 based on a Coanda effect. At this time, an instant vacuum state is produced within the fluid operation tube 3 and further the pressure is decreased by a rapid fluid movement (Bernoulli effect) and a strong absorption force is created by an interaction which accelerates the reduced pressure within the fluid operation tube 3, causing other gases to be transferred rapidly toward the induction drum 41.
Here, through this hydrodynamic phenomenon, the bad smell air which has been given out the excrement space 1-1a through the plurality of flow-through holes 1-1b and water drainage holes 1-21a is absorbed forcibly into the fluid operation tube 3 through the over flow tube 1-213, and this operation continues until when the supplementary water supply is ended by the suction power means 2 (about 5 minutes).
In this case, the duration of discharging the bad smell air corresponds to that of the supplementary water supply, and the time period of the additional supplementary water supply and the discharging time can be controlled based on the typical excrement time period.
Additionally, the fluid (including the bad smell air) moving along the fluid operation tube 3 is injected efficiently into the induction drum 41, and at this time since the cut and curve part of the fluid operation tube 3 is formed as a spherical form having a relative great volume for an efficient absorption, and further the tip end of the straight tube is formed as a deflective form having a slant angle (θ) not to intercept the gar flow, the water drops adhered to the inner wall surfaces of the fluid operation tube 3 is flowed smoothly into the induction drum 41.
After that, the flowed-in-fluid is separated upward and downward depending on their specific gravities, wherein the gas (bad smell air) having a lower specific gravity rises in a rotation air current form along the inner wall surface of the induction drum 41 and then passes through the plurality of the passing hole 421a-1 which are formed evenly overall upper surface of the funnel part 421a over the fall induction tube 421 of the barrel 42. Subsequently, the fluid descends rapidly along the induction part 421b and passes through the discharge induction tube 422 and then is discharged finally to the external discharge tube 1-13. Meanwhile, the water drops having a relative greater specific gravitation than that of the gas fall over a water surface of the cleaning water with their gravity interaction.
As a result, the descending bad smell air passes through the barrel 41 and is discharged to the water purifier tank through the external discharge tube 1-13, and the fine water particles discharged with the bad smell air is guided by the funnel part 421a and then may stay on the induction part 421b or the inner wall surface of the first enlarged part 421c as a form of small water drops, or a portion thereof falls down and then be discharged through the drilled holes 422-13 formed on the back flow prevention plate 422-1. Here, when the air flow is stopped due to the end of the additional supplementary water supply, the water drops staying on the inner wall surfaces of the induction part 421b conglomerates rapidly and at the same time they flow into a center of the back flow prevention plate 422-1, and further sink into the drilled hole tube 422-13 and form a water film valve with water attractive operation, thereby preventing completely the bad smell air discharged out from being back flowed.
Here, even when completing the excrement behavior during supplying the supplementary water to the full water level, as shown in FIG. 14, a user may push the water pouring button 1-211 to drain the cleaning water, and it causes the excrement contained in the excrement space 1-1a to be discharged to the water purifier tank. Meanwhile, as the opening and closing stick 1-211a of the water pouring button 1-211 is rotated upward, the wire 251 of the unlocking member 25 assembled connectively thereto draws backward the push button 24 and returns to its initial position before being pushed.
As a result, the pulling wire 26 connected to the rear end of the push button 24 is pulled, which pulls forcibly the second water level regulator 213 of the second balltap 21 and closes the fill valve of the second balltap 21, causing the stop of the supplementary water supply.
That is, as shown in FIG. 16, through an interaction of the water pouring button 1-211, the push button 24 and the second balltap 21, a second water saving effect can be obtained such that the water is poured on a state that the supplementary water is not filled to the full water level since the supplementary water is no more supplied additionally from the injection nozzle 25.
Meanwhile, water level changes of the cleaning water and the supplementary water are shown in detail, referring to FIG. 17.
Eventually, as shown in FIG. 17, the bad smell air is forcibly absorbed through the suction power means 2 using hydrodynamic principle operation without a separate electric energy, and further the fine water particles discharged together with the bad smell air may stay through their attractive operations within the plurality of drilled hole tube 422-13 formed on the back flow prevention plate 422-1 of the bad smell air discharge means 4 to form a water film valve, thereby preventing the bad smell air from being back-flowed. Additionally, the etiquette bell for offsetting physiological sound produced when excreting is produced by a water supply sound of the supplementary water which is fine-injected from the injection nozzle 25 at a high speed, and further efficient water saving effect is obtained through a water pouring when excreting urine before the cleaning water as additionally supplied supplementary water rises to the full water level from the standby water level of the cleaning water prior to using it.
While this invention has been described in conjunction with the specific embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the preferred embodiments of the invention as set forth above are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit and scope of the invention as defined in the following claims.
