Description

water-saving flush toilet

technical field

The present invention relates to a water-saving toilet bowl, and more particularly, to a water-saving toilet bowl capable of discharging dirt and cleaning the toilet bowl with a small amount of water, by supplying a large amount of air into a sealed water tank to Increase the air pressure in it so that the water pressure remains high until the water in the tank is completely pumped out.

Background technique

In recent years, flush toilets have been widely used in houses and other buildings. The flushing process of this flush toilet will be described below.

The toilet includes a tank with a capacity of approximately 13 L, which is covered with a tank cover and plugged with a water plug. A predetermined amount of water is also contained in the toilet bowl of the toilet.

When the user flushes the toilet after urinating or defecating, the water plug is opened so that the water in the water tank flows directly into the toilet bowl, and then is discharged through the drain pipe together with the dirt.

Said discharge is achieved by siphon action. The pressure difference between the toilet bowl and the drainpipe at the highest water level of the inverted U-shaped pipe (ie, the siphon trap) causes the water and dirt to be discharged together at one time. That is to say, when the flush lever rotates, the water in the water tank will flow directly into the toilet bowl to increase the water level of the toilet bowl. At this time, when the water level increases to be higher than the highest water level of the inverted U-shaped pipe, the water and dirt will be discharged through the drain pipe at the same time.

Plus, the water in the inverted U-shaped tube keeps odors or bugs out of the toilet bowl.

However, in the conventional flush toilet, high water pressure is required to completely discharge water and dirt through the inverted U-shaped pipe, thus resulting in consumption of a large amount of water. For example, each flush consumes 13L of water. That is, since the water pressure depends only on the amount of water in the toilet bowl, a relatively large amount of water is required to obtain a high water pressure.

Therefore, additional objects such as bricks and water-filled bottles are often placed in the tank to reduce water consumption. However, this is not enough to significantly save water consumption, and sometimes the water and dirt cannot be completely drained. Therefore, also need to flush again, increased the consumption of water.

In order to solve the above-mentioned problems, many water-saving devices have been developed. However, the water-saving effect of these water-saving devices is only limited to 6-7L, and the manufacturing cost is increased.

Detailed ways

Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. The same reference numbers are used throughout the drawings to represent the same or similar parts.

1 and 2 show a water-saving toilet according to a first embodiment of the present invention.

As shown in the figure, the flush toilet of the present invention includes a sealed water tank 110 having a drainage hole 140 opened and closed by a spherical plug 120 provided in the water tank, a part of which is connected to a water supply pipe 150 and The drain hole 140 is formed into a funnel shape; the opening device for opening the drain hole 140 by moving the spherical plug 120 is provided in the drain pipe 240 connected with the drain hole 140; The toilet tank 310 connected to the drainpipe 140 to load water, and has a water/dirt discharge hole 320 with a magnet 420 installed at the bottom of the toilet tank 310; and is connected to the opening device through a wire supported on a roller 430 The toilet bowl damper 410 is opened to discharge water/dirt through the water/dirt discharge hole 320 and closed by the magnet 420 .

The opening device includes a pinion gear (pinion gear) 210 equipped with a joystick (flush lever); The opening operation rises to move the ball plug 120; and the elastic spring 230, which is compressed due to the rise of the rack 220, springs open due to the closing operation of the operating lever 211 to make the operating lever 211 returns to the initial position. The driving gear 210 , the rack 220 , and the elastic spring 230 are arranged at the central part of the drain pipe, and a drain channel 250 is formed around the central part.

The water tank 110 is tightly sealed to prevent air leakage when water is supplied through the water supply pipe 150, thereby forming an air pressure when the air is compressed. This makes it possible to clean the toilet bowl 310 with a small amount of water on the order of 1-1.5 L.

The toilet bowl 310 is integrally connected with the excess water channel 330, and when the water/dirt in the toilet bowl 310 is too much, the excess water/dirt is discharged so that the toilet bowl 310 consistently maintains a predetermined water level. That is, the excess water channel 330 maintains a balance between the amount of water supply and the amount of drainage/sewage.

The toilet bowl baffle 410 installed on the water/dirty discharge hole 320 of the toilet bowl 310 is designed to rotate around a hinge 450 to open and close the water/soil discharge hole 320 . In order to ensure the closing operation of the shutter 410 , it is preferable to install a torsion spring on the hinge 450 to provide a restoring force in addition to the magnetic force of the magnet 420 .

The operation of the above described toilet will be described in more detail below.

When the user rotates the joystick 211 in a state where the water tank 110 is filled with water as shown in FIG. The rack 220 pushed up pushes the bottom of the ball plug 120 so that the ball plug 120 can be separated from the drain hole 140 and float on the water.

At this time, when the rack 220 moves vertically upward, the iron wire connected to the bottom of the rack 220 is pulled by the rotation of the roller, thereby opening the shutter 410 . When the ball plug 120 is separated from the drain hole 140 , the water in the water tank 110 is discharged into the drain channel under the high pressure of internal air/water pressure, and then stored in the toilet bowl 310 . At this time, when the baffle 410 is opened, the water and dirt in the toilet bowl 310 will be discharged together through the pressure drop.

At the same time, when the floating ball plug 120 reaches the middle water level of the water tank 110, the water supplied by the water supply pipe 150 acts on the ball plug 120 through the water supply guide 160 installed on the water supply hole 130 to accelerate the movement of the ball plug 120 and reduce the The resistance of the water is small, thereby accelerating the water to be discharged through the drain hole 140.

As described above, the toilet bowl damper 410 closed by the magnet 420 is opened by the user's operation of the lever 211, so that water/dirt can be quickly drained only by reducing pressure. Even when the user releases the force on the lever 211, the toilet bowl damper 410 can maintain an open state to continuously discharge water/soil. That is, high water pressure discharged from the water tank 110 and applied to the toilet bowl 310 is greater than the magnetic force of the magnet 420, so the toilet bowl damper 410 can be maintained in an open state.

When the water/dirt is discharged, the water pressure discharged from the water tank is reduced to less than the magnetic force, after which the toilet bowl baffle 410 closes and pulls the iron wire to release the lever 211 fixed by the elastic spring 230, meanwhile, the rack 220 moves down to Make the joystick 211 return to the initial position.

In addition, the spherical plug 120 in the water tank 110 moves downward by gravity to block the drain hole 140 .

Figure 3 shows a variant of the water/dirt discharge hole. The water/dirt discharge hole of this example extends from the bottom center of the toilet bowl 510 and is inclined to one side, so the pressure of the water/dirt cannot be directly transmitted to the toilet bowl baffle 410 . Reference numeral 520 in FIG. 3 denotes an excess water channel.

Figure 4 shows a water tank according to another embodiment of the present invention. The water tank 1 of this embodiment is hermetically sealed. The rubber washer 18 is installed on the drain hole 5 formed at the bottom of the water tank 1 . To open and close the drain hole 5 , an opening/closing device 3 with a stopper 2 is mounted on the tank 1 . A weight 2a is installed at the inner lower part of the opening/closing device 3 so that the weight of the opening/closing device 3 can be directly downward. A plurality of guides for guiding the vertical movement of the opening/closing device 3 are vertically arranged on the outer wall of the opening/closing device 3 . The water supply hole 14 formed at a distance from the drain hole 5 is connected to a water supply pipe 15, and the water supply pipe 15 is connected with a water supply valve 17 for controlling the water supply amount and an air intake valve 16 for air supply. Drain hole 5 links to each other with drainpipe 24, and air pressure controller 6 is installed in the inner upper part of water tank 1.

As shown in Figure 5, the air pressure controller 6 includes: a cylindrical main body, a hole 6a is formed at the lower part of the side wall of the main body and an exhaust plate 7 is formed at the middle part of the main body; Floating element 8, the floating element 8 is arranged below the exhaust plate 7 and has a plurality of grooves 8a and protrusions 8b; the protective plate 9 arranged on the exhaust plate 7, the protective plate 9 is provided with a spring 10 and The top of the spring 10 is provided with a support plate 11; and an adjusting screw 13 installed on the nut part 12, the nut part 12 is fixed above the support plate 11 and has an air hole 12a for adjusting the internal air pressure. The top of the air pressure controller 6 is covered by a cover 19 having an air hole 19a.

The water tank 1 is connected to the toilet bowl 310 described above with reference to FIGS. 1 to 3 .

When water is supplied to the water tank 1 through the water supply pipe 15, a predetermined amount of air pressure is formed in the inner upper portion of the water tank 1, and the water level increases to a high water level A. When the opening/closing device 3 is opened, water is discharged by water/air pressure until the water level drops to the low water level B (see FIG. 8 ). At this time, the displacement is about 1.5-2.5L.

The opening device of this embodiment is the same as that described with reference to FIGS. 1 to 3 .

The opening/closing device 3 is designed so that the blocking member 2 can be guided downward by the weight 2a to close the drain hole by pressing on the rubber gasket 18 using water/air pressure and gravity.

A water supply valve 17 and an intake valve 16 for controlling the amount of water supplied to the water tank 1 are installed on the water supply pipe 15 to keep the water level and air pressure consistent. On the water supply hole 14 is provided a check valve 14a for preventing water from flowing back into the water supply pipe 15 when the internal pressure of the water tank increases to a predetermined level.

As shown in FIGS. 6 and 9 , showing a second embodiment of the present invention, a toilet seat 50 on which a user can sit is mounted on a toilet bowl 31 via a hinge 54 . The elastic tube 52 is installed at the bottom of the toilet seat 50 . The elastic tube 52 is made of rubber or silicon material, so that its inner hollow can easily return to its original shape even when it is compressed. That is, the elastic tube 52 is designed as an air pump. In addition, the elastic tube 52 is equally divided into two halves along the shape of the toilet seat 50 . The first check valve 55 is installed at the distal end of the two bisected elastic tubes 52 . The two bisected elastic tubes 52 are joined behind a hinge 54 to form one tube. The single pipe 52 is connected to an air injection pipe 52 a through a second check valve 56 . This air injection pipe 52a extends in the water tank, so its top end is set at a portion slightly higher than the low water level B. As shown in FIG. A third check valve is installed at the distal end of the air injection pipe 52a.

When a user sits on the toilet seat 50, the elastic tube 52 is compressed so that air directly enters the air injection tube 58a, so that the pressure in the air injection tube 58a becomes higher than the internal air pressure of the tank 1. Accordingly, air from the air injection pipe 58a is injected into the water tank 1 to increase the internal air pressure of the water tank 1 . When too much air is supplied into the water tank 1, the amount of water supplied decreases. In this case, the air pressure controller 6 is operated to maintain the internal air pressure at a predetermined level.

Rubber washers 180, 260 and 460 are installed between the drain hole 5 and the blocking member 2, between the rack 220 and the drain passage 250, between the magnet 420 and the baffle plate 410, and between the air injection pipe 52a and the water tank 1, to Prevent water leaks.

The operation of the second embodiment will be described in detail below.

When the opening/closing device 3 is raised by the opening device, the water is drained through the drain pipe 24 to remove the water/dirt in the toilet bowl. When the water/dirt in the toilet bowl is discharged, the opening/closing device is closed by the weight 2a, and water is supplied to the water tank 1 through the water supply hole 16, and an air pressure is formed in the water tank 1 at the same time.

When the air pressure in the water tank 1 increases above the predetermined pressure, a part of the air in the water tank directly enters the groove 8a of the floating element 8 through the hole 6a formed on the side wall of the air pressure controller to push the protective plate 9 to block the exhaust plate 7, and then the gas is exhausted to the outside through the exhaust plate 7 through the air hole 12a formed on the nut portion 12 and the hole 19a formed on the cover 19.

When a part of the air in the water tank is discharged to the outside, the protective plate 9 blocks the exhaust plate 7 by the elastic force of the spring 10 . That is to say, when the internal air pressure is greater than the predetermined pressure and the water is discharged to the low water level B, the protective plate 9 will be pushed up quickly to open the exhaust plate 7, thereby keeping the air pressure at the predetermined level. The predetermined value of the internal air pressure can be adjusted by adjusting the screw 13 to change the supply/drainage.

That is, by adjusting a predetermined value of the internal air pressure of the water tank 1, the water tank 1 can be used together with a conventional toilet bowl connected with an inverted U-shaped pipe.

Industrial Applicability

In addition, the water-saving toilet of the present invention can save water by eliminating the inverted U-shaped pipe and forming air pressure in the sealed water tank to increase water pressure to reduce water discharge. In addition, the water saving toilet has a tank that can be used with a conventional toilet bowl connected with an inverted U-shaped tube.

Those skilled in the art will appreciate that various modifications and changes can be made to the present invention. Thus, it is intended that the present invention includes the modifications and variations of this invention that come within the scope of the appended claims and their equivalents.
