Description

DESCRIPTION

Variable Water Saving Toilet Sewage Flush Device

Background of the invention

1. Field of the invention

The present invention relates to a sewage discharge device for a variable type water saving flush toilet, and more particularly, to a sewage discharge device for a variable type water saving flush toilet. in which a part of the discharge water flows through a discharge water inlet passage is branched so that when the discharge water stored in an auxiliary tank arranged on the outer circumference of a sewage discharge pipe of the toilet reaches a preset amount, the wastewater contained in a bowl is discharged to the outside by the weight of the auxiliary tank.

2. Description of Related Art

In general, a flush toilet employs the principle of a siphon in which a certain amount of water is contained in a toilet bowl to gently remove bad odor or excretion that rises from a waste outlet port and Cleanly wash the inside of the cup.

This siphon principle refers to a principle that when the water level in an inverted U-shaped pipe forms a state of equilibrium with that in the toilet bowl, the water is stagnant, while when the level of the water in the toilet bowl suddenly increases, the water contained in the bowl is discharged to the outside due to a pressure difference between the toilet bowl and the siphon tube in a relatively low pressure state while accompanied by from an increase in pressure inside the toilet bowl.

As shown in Figure 1, a typical flush toilet includes a bowl 2 configured to hold a predetermined amount of water, and a residual flushing water tank 1 arranged higher than the bowl 2 and configured to store a predetermined amount of water. predetermined amount of residual washing water, the residual washing water tank is connected to the bowl 2 through a water supply passage 2a closed by a packing valve 5, so that the packing valve 5 operated cooperatively with a flushing lever installed in the residual flushing water tank 1 opens a water supply port 10 by manipulating the flushing lever 3 to allow the water stored in the residual flushing water tank 1 to be rapidly supplied to cup 2 through water supply passage 2a. Therefore, the waste including feces and urine precipitated in the bowl is discharged outside through a water drainage passage 2b through a siphon drainage siphon 2c in which the water to be draining along the bowl water drainage passage 2b is created by a hydraulic pressure generated in the bowl 2 with an increase of the water level in the bowl 2.

However, a conventional flush toilet as described above involves a problem in that a water level higher than the height of the drain siphon 2c must be maintained to prevent backflow of bad odor from the toilet into the bowl, and a quantity of water capable of overcoming a hydraulic pressure at the height of the drain siphon 2c during flushing of the toilet, which leads to an increase in the quantity of water consumed.

In addition, since the existing flush toilet must comply with a regulation that prescribes that the diameter of a sewage discharge pipe must be set to more than 45mm, that is, generally around 45-55mm, which is determined according to KS standards to smoothly discharge the sewage from the bowl, a so-called siphon phenomenon is made to occur in order to wash the sewage inside the bowl by suction force. In order to cause the siphon phenomenon, it is required that more than 60 ml of water be supplied to the inside of the cup at least once. For this, in the case of the conventional flushing toilet, a water tank is installed in which a certain amount of water is stored at normal times, and then water is supplied to the inside of the bowl through the water supply passage. water in fluid communication with the water tank and bowl by opening an open/close plug attached to an opening of a water discharge pipe having a diameter of about 65mm or less, which was installed in the inside of the water tank so that the siphon phenomenon occurs to perform the washing operation.

Therefore, the conventional flush toilet also carries the problem that although the flush water is supplied to the inside of the bowl from a water pipe having an opening of about 15mm, the diameter of the flush pipe of sewage of the bowl is typically no more than 45-55mm, so the siphon phenomenon cannot occur, and the discharge water is discharged to the outside through the sewage discharge pipe as it is, which makes it impossible to wash out the sewage contained in the bowl.

For this reason, since a male urinal is directly connected to a water pipe in use, automatic flushing by means of a sensor or the like has become widespread. However, a toilet stool cannot wash the sewage by connecting it directly to the water pipe for the above reason, and therefore an automatic toilet stool could not be marketed.

In addition, the existing flush toilet (a flush value type toilet product with a water feed tube having a 2.54 cm (1 inch) opening is partially excluded) must necessarily have a flushing function. water tank to allow bowl washing. For this reason, there is also a space restriction because the size of the toilet cannot be reduced due to a design limitation and the water tank. In addition, a water tank and a toilet stand are integrally made of clay in a so-called "one-piece flush toilet", the defect rate increases and thus the production yield decreases, resulting in in an increase in the cost of clay products.

Furthermore, it may be the case that even if a water leak occurs due to a defect of a water supply and discharge pipe installed inside the water tank, it is difficult for a user to easily detect the water leak and Therefore, the user cannot recognize the water leak until he checks an invoice for the water supply and drainage service. In addition, since the so-called flash toilet used in a common bathroom or a public place such as an office building or the like does not include a water tank, it must be additionally equipped with a water pipe having a diameter of 25mm (1 inch) apart from a general water pipe that has a diameter of 15mm so that it can be directly connected to the water pipe to supply a large amount of water at the same time in use. For this purpose, a large installation cost is additionally required, and a phenomenon called "water hammer" during flush lever operation is accompanied by a serious noise, which makes it impossible to use the instant toilet in a harsh environment. overall domestic.

In addition, Korean Patent No. 10-1131810 discloses a water-saving flush toilet and has a variable double straight pipe, in which the variable double straight pipe is configured to operate in an existing water flow path and in the form of cup rim When there is a water level inside a bowl during a faucet discharge water supply, the variable double straight tube moves down so that the sewage can be discharged, but the hydraulic pressure of the discharge water drops drastically in a water supply passage fluidly communicating with a water tank and the bowl and a water supply passage formed at the edge of the bowl, which ultimately makes it impossible to use discharge water from a faucet and thus Therefore, it causes a problem associated with the washing of the waste water contained in the bowl. In addition, it is difficult to control the delay of the sewage discharge time when the variable double straight pipe moves downward during the discharge of sewage, which occasionally results in backflow of some sewage.

In addition, Korean Patent No. 10-1131810 also discloses that flush water should be supplied to the bowl until the variable double straight pipe moves down to discharge the sewage, and the supplied flush water immediately mixes with the waste water. contained in the bowl and thus also become wastewater. As a result, residual washing water is wasted, leading to a halving of the water-saving effect.

In addition, Korean Patent No. 10-1131810 also discloses that the double variable straight pipe uses water stored in an auxiliary tank arranged on the outer circumference of a sewage discharge pipe as part of the sewage to be discharged, and thus the variable double straight pipe is clogged by the sewage introduced into the auxiliary tank after a predetermined amount of time, which causes the sewage discharge pipe to malfunction, leading to the deterioration of the durability of the discharge pipe of sewage. And Korean Patent No. 10-1638427, which is considered to be the closest prior art, discloses a discharge water branch unit fluidly connected with the discharge water inlet passage and configured to allow a part of the discharge water flows through the discharge water inlet passage to branch when the discharge water enters the bowl; and the auxiliary tank is configured to store in this branch discharge water from and supplied to the discharge water branch unit.

One end of the corrugated tube 200 can be tightly fixed to the connecting tube 120, and can be connected to the connecting tube 120 in a screwed manner.

The corrugated tube 200 serves to form a flow path of sewage drained from the bowl 110, and is a flexible tube that can be bent in one direction by an external force.

Discharge Water Branch Unit 300

The discharge water branch unit 300 according to the present invention is fluidly connected with the discharge water inlet passage 101 and serves to allow a part of the discharge water flowing through the discharge water inlet passage 101 When the discharge water is fed into the bowl 110, when the discharge water is supplied to the bowl 110 to wash the bowl 110, part of the discharge water branched from the branch unit 300 discharge water from the discharge water inlet passage 101 is introduced and stored in an auxiliary tank 420 of the sewage discharge pipe 400 to be described later so that the sewage discharge pipe 400 rotates by the own weight of the auxiliary tank, which is involved in the discharge of wastewater.

The discharge water branch unit 300 includes a branch corrugated pipe 310 and a branch water inlet portion 320 .

The corrugated branch pipe 310 is coupled at an upper end thereof to the discharge water inlet passage 101 and is connected at a lower end thereof to the auxiliary tank 420.

The branch water inlet portion 320 is connected to the upper end of the branch corrugated pipe 310 and is disposed inside the discharge water inlet passage 101 so as to allow introduction of branch discharge water. The introduced branch water flows and is stored in the auxiliary tank 420 of the sewage discharge pipe 400 which will be described later through the corrugated branch pipe 310.

When provided, the odor prevention valve 321 closes under its own weight upon interruption of the flush water supply to prevent malodour from the toilet from flowing into the bowl 110 and then into a bathroom through the toilet. through the discharge water inlet passage 101.

Figure 5 is a cross-sectional view illustrating the operation of a sewage discharge pipe according to the present invention.

Sewage Discharge Pipe 400

Referring to Figures 2 and 5, the sewage discharge pipe 400 according to the present invention is connected to the corrugated pipe 200. When the discharge water introduced through the discharge water branch unit 300 is stored in the auxiliary tank 420, a load is applied to the sewage discharge pipe 400 to move the sewage discharge pipe 400 downward. to discharge the sanitary wastewater contained in the bowl to the outside.

The sewage discharge pipe 400 includes a cylindrical main discharge pipe 410 connected to one end of the corrugated pipe 200 and an auxiliary tank 420 disposed on an outer circumferential surface of the main discharge pipe 410 to circumferentially surround the main discharge pipe 410 . .

The main discharge tube 410 is connected to the corrugated tube 200 and serves to discharge the sewage outside.

The auxiliary tank 420 is disposed on an outer circumferential surface of the main discharge pipe 410 and is configured to store in this branch discharge water from and supplied to the discharge water branch unit 300 . The auxiliary tank 420 has an auxiliary drain hole 422 formed therein to allow discharge water stored in a lower portion thereof to be discharged. The auxiliary tank 420 serves to rotate the sewage discharge pipe 400 by its own weight of the branch discharge water from the discharge water branch unit 300 and stored therein with the supply of the discharge water to the bowl 110 to wash the bowl 110 so that the sewage contained in the bowl 110 can be discharged outside through the main discharge pipe 410 connected to the corrugated pipe 200. At this time, when the branch discharge water from the discharge water branch unit 300 reaches a preset amount, the auxiliary tank 420 moves downward under its own weight so that the sewage is discharged outside through of the main discharge pipe 410, and the time during which the wastewater is discharged to the outside through the main discharge pipe 410 is delayed in proportion to a discharge rate at which the discharge water supplied to the auxiliary tank 420 is drains through auxiliary drain hole 422.

At this point, the auxiliary tank 420 includes a connection part 421 provided at an upper portion thereof for connecting to the corrugated branch pipe 310, and an auxiliary drain hole 422 formed at the outer circumference of a lower portion thereof for allow the discharge water stored in the auxiliary tank to drain through it.

By virtue of the configuration described above, when the sewage is not discharged, the sewage discharge pipe 400 is kept in a vertical state. In other words, when the discharge water does not flow into the discharge water branch unit 300, the sewage discharge pipe 400 does not rotate, so that the cup 110 can keep a stable amount of water stored in it and , therefore, suppresses the adhesion of waste including feces and urine to the inner wall of the bowl 110 and generation of malodour. Subsequently, when a user manipulates a discharge water valve, lever or the like to supply discharge water to the discharge water inlet passage 101 after responding to the call of nature, a part of the discharge water flowing to through the discharge water inflow passage 101 branches from the discharge water branch unit 300 and is stored in the auxiliary tank 420 of the sewage discharge pipe 400.

When the branch discharge water from the discharge water branch unit 300 reaches a preset amount in the state shown in Figs. 2 and 3, the sewage discharge pipe 400 rotates downward by its own weight. of the auxiliary tank as shown in Figs. 4 and 5. The state in which the sewage discharge pipe 400 has been rotated is a state in which the main discharge pipe 410 is oriented horizontally to allow sewage discharge. 110 cup residuals.

The discharge water stored in the auxiliary tank 420 of the sewage discharge pipe 400 is a source of energy to move down the main discharge pipe 410 due to the weight of the discharge water, and plays an important role in delaying the discharge. wastewater discharge time.

As such, when the sewage discharge pipe 400 rotates downward, the sewage contained in the bowl 110 is discharged outside through the main discharge pipe 410 of the sewage discharge pipe 400 through the corrugated pipe 200 . At this time, the branch discharge water stored in the auxiliary tank 420 is slowly drained downward to the outside through the auxiliary drain hole 422.

Furthermore, as the flushing water is introduced into the bowl 110 through the flushing water inlet port 111 through the flushing water inlet passage 101, it washes the inner wall of the bowl 110 and the waters Sewage drawn from bowl 110 is also discharged outside through main discharge pipe 410 of sewage discharge pipe 400 through corrugated pipe 200 .

The introduction of the flush water into the bowl 110 through the flush water inlet port 111 or through the flush water inflow passage 101 occurs a little later than the branching of the flush water from the discharge water branch unit 300. Therefore, the introduction of the flushing water into the bowl 110 occurs slightly slower or almost simultaneously with the rotation of the sewage discharge pipe 400 to discharge the sewage. As such, when flush water is supplied to the bowl 110 slightly slower than or nearly simultaneously with a sewage discharge time point through the sewage discharge pipe 400, the flush water supplied to the bowl 110 can wash the inside of the bowl 110 without mixing with waste water contained in the bowl 110, and therefore can be involved only in the washing of the bowl 110. As such, the discharge water supplied to the bowl 110 is involved only in the washing of the bowl 110, so that it can be prevented from mixing with the sewage contained in the bowl 110 and rising in the bowl 110, and thus the bowl 110 can be kept in a clean state and can be cleaned. exhibit a water-saving effect.

When the branch discharge water from the discharge water branch unit 300 and stored in the auxiliary tank 420 is drained in a certain amount through the auxiliary drain hole 422, the sewage discharge pipe 400 returns to normal. original position by an elastic force of the elastic unit 500 as shown in Figures 2 and 3. The sewage discharge pipe 400 is kept in a rotated state until the discharge water is completely drained out from the sewage pipe. auxiliary tank 420 of the sewage discharge pipe 400 through the auxiliary drain hole 422, and thus the discharge time of the sewage discharged outside through the main discharge pipe 410 of the discharge pipe 400 may be delayed of sewage. As such, the discharge time of the sewage discharged to the outside through the main discharge pipe 410 is delayed so that the sewage contained in the bowl 110 can be fully discharged without residual sewage, resulting in an increase in washing efficiency.

The adjustment of the discharge time of the sewage discharged through the main discharge pipe 410 of the sewage discharge pipe 400 is associated with an increase or decrease in the drainage speed of the discharge water drained through the hole 422 of auxiliary drain. Ultimately, the discharge time of the sewage depends on the size of the auxiliary drain hole 422.

The discharge time of the sewage discharged through the main discharge pipe 410 can be controlled by variably adjusting the area of the auxiliary drain hole 422 formed at the rear end of the auxiliary tank 420.

As shown in Figs. 2 and 3, when the sewage discharge pipe 400 returns to its original position, the washed water contained in the bowl 110 is prevented from being discharged outside. In this case, the time point where the sewage discharge pipe 400 returns to its original position is an end time point of the discharge water supply to the discharge water inlet passage 101 .
