Description

Water saving closet

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet, and more particularly, to a water-saving toilet in which the opening degree of a drain valve is different from a cleansing water discharge with respect to faeces and urine.

A general flush toilet is mainly composed of a toilet bowl for receiving excrement, a sewage pipe for discharging the sewage together with the washing water, and a washing water tank for discharging the washing water by link operation.

In this case, the link is mainly located in front of the washing water tank, so that it can be easily hand-operated.

The sewage pipe from which the dirt is discharged is formed by the S-shaped trap (siphon tube) having a point higher than the lowest position in the toilet pot, so that the washing water always has a certain amount at all times, thereby preventing the odor from rising on the sewer pipe. In addition, by having the S-shaped trap, when the washing water over a certain amount is discharged at a time, the water level inside the toilet bowl temporarily becomes high, so that all the washing water and the dirt in the trap can be discharged to the sewer by the siphon phenomenon. The rinse water poured into the toilet bowl while the rinse water and the dirt are simultaneously discharged is used to replenish the trap again.

However, when using a regular flush toilet, the amount of flushing water required to drain the water is about 13 liters, and a family of four will use one full-sized refrigerator as a flushing flushing water. In general household flush toilet, this amount of washing water may not be a problem. However, if the environment such as submarine or airplane is needed, it is necessary to adjust the amount of washing water used. Therefore, the water drop using the siphon phenomenon is inappropriate for use. For this reason, in environments such as a submarine or an airplane, a method of washing the toilet by strongly spraying a small amount of washing water using a pressurizer, or cleaning the toilet with a small amount of a special washing liquid instead of ordinary water is used.

In the case of a flush toilet used in a submarine, it is necessary to keep the silencer at rest during operation in the sea. Therefore, it is necessary not only to minimize the amount of washing water used for discharging the dirt, but also to reduce noise There is a need. In the case of general feces, the noise generated when discharging dirt is more than 80dB, which is close to the noise in the subway.

In addition, since space saving is very important because of the location characteristic of the submarine, it is necessary to minimize the space occupied by the toilet.

A problem to be solved by the present invention is to design a flush toilet for a submarine which is capable of discharging excretion without generating a lot of noise while using as little washing water as possible.

The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a toilet comprising: a toilet bowl; A drain pipe connected to a lower portion of the toilet bowl; A drain valve that can be opened and closed at a portion where the toilet bowl and the drain pipe are connected; A flush portion connected to the washing water supply portion formed on the upper portion of the toilet bowl to discharge the washing water to the toilet bowl through the washing water pipe; A valve closing portion for maintaining the drain valve in a closed state and providing an elastic force to maintain the flush portion in a state in which the washing water does not pass; And a pedal connected to the drain valve, the flush portion, and the valve closing portion, the opening degree of the drain valve is changed according to the amount of insertion of the pedal when the pedal is depressed by a user, The flushing portion discharges the washing water to the toilet bowl through the washing water supply portion.

The drain pipe may be formed in a straight line.

The material constituting the toilet may be SUS316L stainless steel.

The manner of connecting the drain valve, the flush portion and the valve closing portion of the toilet bowl to the pedal may be a link structure.

The link structure includes a pedal link having one end connected to the pedal and connected to the transmission shaft and the first shaft, a flush link having one end connected to the transmission shaft and the other end connected to the flushing portion, And a valve link having one end connected to the drain hinge and the other end connected to the drain hinge, wherein the valve shaft is connected to the first shaft.

The volume of the washing water supplied to the toilet bowl from the flush part may be smaller than 5 liters.

The drain valve may be opened or closed by rotating about a drain hinge formed at one side of the drain valve.

The opening degree of the drain valve can be increased as the amount of the pedal is increased.

A flushing block connected to the pedal, the flushing block being disposed with a limiter and a clearance, a piston rod connected to the limiter to which the upper surface of the flushing block is contactable, a piston rod connected to the lower end of the piston rod, And a flush cylinder connected to the flush piston to provide an elastic force, the flush cylinder including an inner surface contacting the outer surface of the flush piston so that the flush piston can move upward and downward, When the flushing block is lifted, the flushing piston is lifted from the flushing water passage by pushing up the limiter after the flushing block has risen by the clearance.

The upper surface of the flush block may contact the limiter when the amount of the pedal is equal to the threshold.

The embodiments of the present invention have at least the following effects.

The odor can not come up through the sewer without using the S-trap using the openable drain valve.

Depending on the type of excrement, the user can adjust the degree of washing through the pedal and use the I-shaped sewer pipe without using the S-shaped trap to save the washing water and minimize noise during cleaning.

Space can be saved by arranging all the components of the toilet under the area where the user is seated.

The user can easily sense whether the power required to depress the pedal is increased rapidly without having to visually determine whether or not the answer amount has reached the threshold value, thereby easily determining whether or not the water is to be lowered.

The effects according to the present invention are not limited by the contents exemplified above, and more various effects are included in the specification. Other effects not mentioned may be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, the configuration of a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a toilet according to an embodiment of the present invention.

1, the toilet 10 includes a toilet bowl 20 and a drain pipe 31, a pedal 40, and valve closure portions 50 and 51. The operation of components other than the toilet bowl will be described later in detail using a side view according to an embodiment of the present invention.

The toilet bowl (20) includes a seat (21) on which a person can sit. In an embodiment of the present invention, the seat is shown as being flat in the horizontal direction, but the seat is not limited thereto, and a lid-type seat used in a general toilet can be used.

The toilet bowl (20) is formed in a funnel shape that becomes narrower as it goes downward, so that the toilet bowl (20) can receive the excrement and collect the excrement at a position close to the drain hole (22). The drain port 22 is located at the bottom of the toilet bowl 20, is connected to the drain pipe 31, and is closed with a drain valve 30 to be described later.

The drain pipe (31) is located at the lower portion of the toilet bowl (20). The drain pipe 31 receives the excretion discharged through the drain port 22 of the toilet bowl 20 and discharges the discharged excreta to a sewage facility (not shown).

On the other hand, the drain pipe 31 may be formed into a straight long shape in the height direction. Therefore, the excretion discharged through the drain port 22 of the toilet bowl 20 drops freely through the drain pipe 31 by gravity and is discharged to the sewage system (not shown).

2 is a left side view of a toilet according to an embodiment of the present invention.

Referring to FIG. 2 and FIG. 1, the pedal 40 is located on the left side of the drain pipe 31, and the pedal is connected to one end of the first pedal link 41. The other end of the first pedal link 41 is connected to the transmission shaft 80 and the other end of the second pedal link 42 is connected to the transmission shaft 80 at the same point. The axis of the transmission shaft 80 to which the pedal links 41 and 42 meet is connected to the toilet bowl body 70 so that the position does not move from the toilet bowl body but rotates about the center of the transmission shaft 80 only. The pedal links 41 and 42 are fixed to the transmission shaft 80 so that the transmission shaft 80 also rotates in accordance with the rotation of the pedal links 41 and 42 and the rotation of any one of the pedal links 41 and 42 The other rotates. Accordingly, the pedal links 41 and 42 serve to transmit the external force to other members when the pedal 40 receives an external force and the pivotal movement occurs. The direction in which the pedal 40 and the pedal links 41 and 42 are present is not limited to the left as in the present embodiment.

One end of the second pedal link 42 and one end of the first valve link 43 and one end of the valve closing piston 51 are connected at a single point, The first shaft 46 is not fixed to the toilet bowl body 70 or the drain pipe 31 and the second pedal link 42, the first valve link 43 and the valve closing piston 51 are connected to the first shaft 46) as an axis so as to freely rotate. Accordingly, the first shaft 46 serves to transmit the external force transmitted through the pedal links 41, 42 to the valve closing piston 51 and the first valve link 43.

The other end of the first valve link 43 meets the second shaft 47 at one end of the second valve link 44 and is fixed to the second shaft 47. The second shaft 47 is not fixed to the toilet body 70 or the drain pipe 31 and the connected valve links 43 and 44 are freely rotatable about the second shaft 47 as an axis. Accordingly, the second shaft 47 serves to transmit an external force transmitted through the first valve link 43 to the second valve link 44. [

The other end of the second valve link 44 is connected to the drain hinge 32 so as not to be rotatable. The drainage hinge (32) penetrates the drain pipe (31) in the lateral direction so that the movement is fixed but is rotatably supported. Accordingly, the drain hinge 32 also rotates in accordance with the rotation of the second valve link 44.

The other end of the valve closing piston 51, one end of which is connected to the first shaft 46, is in the valve closing cylinder 50. The valve closing cylinder 50 is structured to surround the valve closing piston 51 so as to be able to perform the cylinder-piston motion in a pair with the valve closing piston 51 when the first shaft 46 is rotating. One end of the valve closing cylinder 50 is connected to the valve closing piston 51 and the other end is connected to the valve closing cylinder 50 to interrupt the piston movement of the valve closing piston 51, There is an elastic member (not shown) for positioning the elastic member. The elastic member (not shown) may be a spring, but is not limited thereto.

3 is a right side view of a toilet according to an embodiment of the present invention.

Referring to FIG. 3, it can be seen that the transmission shaft 80, which serves to connect the pedal links 41 and 42, is connected to one end of the flush link 45. Therefore, the rotation of the transmission shaft 80 also causes the flush link 45 to rotate.

The other end of the flush link 45 is connected to the flush block 62 of the flush portion 60. The flush block 62 is configured to move upward and downward along the outer surface of the block guide 65. Accordingly, the flush block 62 moves up or down along the direction of the block guide 65 in accordance with the rotation of the flush link 45. [

The configuration of the links 41, 42, 43, 44 and 45 and the axes 32, 46, 47 and 80 has been described with reference to one embodiment of the present invention. However, The configuration is also possible.

The limiter 66 is positioned above the flush block 62 and at a certain clearance with one end of the flush block 62. The piston rod 67 extends through the limiter 66 and into the flush cylinder 61. [ The flush block 62 surrounds the block guide 65 but does not have a direct coupling relationship with the limiter 66 or the block guide 65. [

The flush unit 60 serves to control the supply of the washing water. And thus may include an inlet 64 for receiving the washing water. The inflow portion 64 serves to receive the washing water from the external washing water inflow source (not shown). The main object of the present invention is to operate in an environment where extreme pressure and internal pressure are imbalanced such as a submarine or an airplane. When the washing water flows directly from the outside, the backwash is generated or the washing water is inflowed with an excessively strong pressure Failure of the device may occur. Therefore, a washing water inflow source (not shown) is required which stores the external washing water by using the partition wall structure, and supplies the washing water to the inflow portion 64 at a slightly higher pressure than the indoor pressure.

The flush pipe 63 serves as a passage through which the washing water passes so that the washing water is supplied to the toilet bowl through the washing water supply part 23 when discharging the washing water.

4 is a rear view according to an embodiment of the present invention.

Referring to FIG. 4, it can be seen that the transmission shaft 80 is connected to the pedal links 41, 42 and the flush link 45 through the toilet bowl body 70.

FIG. 5 is a cross-sectional view of a toilet bowl-drain pipe showing a state in which a drain valve is closed according to an embodiment of the present invention.

5, the toilet bowl 20 and the drain pipe 31 are connected to each other through the drain hole 22, and the drain valve 30 is located at the connection portion. The drain port 22 is formed in a straight line so that the slurry can be discharged directly by free fall. The drain valve 30 prevents the transfer of material between the drain port 22 and the drain pipe 31. One end of the drain valve 30 is supported by the drain hinge 32 and the other end thereof is not. The drain valve 30 can be opened and closed and the drain valve 30 can be rotated around the drain hinge 32 by the rotation of the drain hinge 32. [ In the embodiment of the present invention to be described later, a state in which the drain valve 30 is opened and rotated together with Fig. 7 will be described. The drain valve 30 is rotated in one direction by the drain hinge 32 in the embodiment of the present invention. However, the present invention is not limited to this, and it is possible to open and close the drain valve 30 in a double- Valve type can be used.

Hereinafter, the operation of the embodiment of the present invention will be described with reference to Figs. 6 to 11. Fig.

6 is a left side view showing the position of the link 41, 42, 43, 44, 45 when the insertion amount of the pedal 40 according to an embodiment of the present invention is below the threshold value.

In case of urination, the toilet only needs to discharge the urine to the outside in order to minimize the hygiene, and it is not necessary to wash the toilet by using the washing water. Therefore, in such a case, when the pedal 40 is depressed below the threshold value by applying an external force such as stepping on the pedal or pressing with the hand, only the urine is discharged without discharging the washing water.

Referring to FIG. 6, the pedal 40 is slightly depressed, and the first pedal link 41, to which the pedal 40 is connected at one end, rotates clockwise. The other end of the first pedal link 41 is connected to the transmission shaft 80 fixed to the toilet bowl body 70 and is also connected to one end of the second pedal link 42 so that the transmission shaft 80 The first pedal link 41 rotates about its center.

Since the first pedal link 41 is rotated in the clockwise direction as described above, the second pedal link 42 connected thereto also rotates in the clockwise direction about the transmission shaft 80. The second pedal link 42 engages the valve closing piston 51 and the first valve link 43 on the first shaft 46 and thus transmits the rotation.

Since the first shaft 46 is not fixed to the toilet bowl body 70 or the drain pipe 31, the first shaft 46 is rotated in the reference lower left direction in FIG. 6 by the clockwise rotation of the second pedal link 42. Accordingly, one end of the first pedal link 43 connected to the first axis 46 also moves to the reference lower left in Fig.

The other end of the first valve link 43 is engaged with one end of the second valve link 44 in the second shaft 44 and the second shaft 44 is fixed to the toilet bowl body 70 and the drain pipe 31 The one end of the second valve link 44 is rotated leftward and downward by the left-down movement of the first valve link 43. At this time, the other end of the second valve link 44 is connected to the drain hinge 32 fixed to the drain pipe 31, so that the drain hinge 32 is rotated clockwise about the drain hinge 32.

7 is a cross-sectional view of a pot-to-drain pipe showing a situation where a drain valve according to an embodiment of the present invention is opened by a pedal operation.

Referring to FIG. 7, the drain hinge 32 rotates in the clockwise direction by the transmitted motion, and the drain valve 30, which is connected to the drain hinge 32 at one end, is rotated clockwise. As a result, the drainage hinge 32 is opened, so that the excrement collected in the drainage port 22 is discharged to the drainage pipe 31 by the gravity due to the shape of the concave reservoir 20.

It is also understood that the rotation amount of the links 41, 42, 43, 44 is determined according to the amount of the pedal 40 to be pushed so that the amount of rotation of the drain hinge 32 is also determined by the amount of the pedal 40 . This is because the amount of rotation of the drain hinge 32 depends on how much the connected second valve link 44 rotates.

6, the valve closing piston 51 is connected to the first shaft 46 and is pushed into the valve closing cylinder 50 as the first shaft 46 rotates in the lower left direction. At this time, since the first shaft 46 rotates in the lower left direction, the valve closing portions 50 and 51 remain horizontal and the valve closing piston 51 can not move horizontally to the left, Can be connected to the toilet body 70 with a hinge and can be tilted for smooth movement of the valve closing piston 51.

Since the valve closing cylinder 50 is provided with an elastic member (not shown) that provides an elastic force in the direction against the movement of the valve closing piston 51, the valve closing piston 51 is located inside the valve closing cylinder 50 An elastic member (not shown) is compressed or tensioned to have a potential energy by an elastic force and apply an elastic force to the valve closing piston 51 in a direction opposite to the direction of its movement.

3, the flush link 45 receives the rotation transmitted by the first pedal link 41 through the transmission shaft 80. As shown in Fig. 6, when the first pedal link 41 is rotated in the clockwise direction, the flush link 45 also rotates in the clockwise direction with respect to the transmission shaft 80.

At this time, since the other end of the flush link 45 is connected to the flush block 62, the flush link 62 lifts the flush block 62 upward while rotating clockwise. However, the flush block 62 does not rise enough to reach the limiter 66. Therefore, although water will be described later in detail with reference to FIG. 10 and FIG.

As a result, when the stroke of the pedal 40 does not reach the threshold value, the drain valve 30 is opened but the supply of the rinse water does not occur. Therefore, only urine can be discharged if water is not needed.

An elastic force is applied to the valve closing piston 51 by an elastic member existing in the valve closing portions 50 and 51 to release the valve closing piston 51 from the pedal 40, So that the links 41, 42, 43, 44, 45 and the pedal 40 return to their original positions. Therefore, the drainage hinge 32 also returns to its original position, and the drainage valve 30 also blocks the point where the toilet bowl 20 and the drainage pipe 31 meet.

Next, the operation of the toilet will be described with reference to FIGS. 8 to 11, in which the amount of the pedal according to the embodiment of the present invention is equal to or greater than the threshold value.

FIG. 8 is a left side view showing the position of the link when the insertion amount of the pedal according to the embodiment of the present invention is equal to or greater than the threshold value. FIG. A right side view showing the position of the piston.

Referring to FIG. 8, it can be seen that the rotation of the links 41, 42, 43, 44 and 45 occurs more frequently than the left side view shown in FIG. 6 because the pedal stroke has occurred above the threshold value. Therefore, the drain valve 30 is opened more than in the case of FIG. 7, and the valve closing piston 51 is also pushed farther to the left than in the case of FIG. 6 and further inserted into the valve closing cylinder 52.

9, it can be seen that the flush block 62 contacts the limiter 66 and pushes the limiter 66 up. The specific operation of the flush unit 60 will be described with reference to FIGS. 10 and 11. FIG.

FIG. 10 is a cross-sectional view showing the state of the flush part when the insertion amount of the pedal according to the embodiment of the present invention is less than the threshold value, and FIG. 11 is a view showing the state of the flush part when the insertion amount of the pedal according to the embodiment of the present invention is equal to or larger than the threshold value Fig.

10, the flush block 62 has an inner shape corresponding to the outer circumferential surface of the block guide 65, and is configured to move upward and downward along the outer surface of the block guide 65. As shown in FIG.

The block guide 65 has a latching portion inside the flushing cylinder 61 and is fixed from the flushing cylinder 61.

The flushing cylinder 61 is correspondingly opened to the side of the flush piston 68 so that the flushing piston 68 and the flushing piston 68 can perform the cylinder-piston movement. The end of the flushing cylinder 61 is connected to the inlet 64 and the washing water pipe 63, Respectively. The flush cylinder 61 may be filled with liquid for buffering for smooth movement.

The flush piston 68 is configured to perform a piston movement in the flush cylinder 61. When the pedal is not operated, the flush cylinder 61 is connected to the flush cylinder 61, the washing water pipe 63, 64 to prevent the washing water from being transmitted from the inflow portion 64 to the washing water pipe 63.

The upper end of the flush piston (68) is connected to a piston rod (67) extending above the flush cylinder (61). The piston rod 67 has a limiter 66 above the flush cylinder 61 and is spaced upward from the flush block 62 when the pedal is not actuated. The limiter 66 is wider in the horizontal direction than the piston rod, which is a limit to which the flush block 62 can move upward.

A flush spring 69 is present in the flush cylinder 61. The flush spring 69 is provided on the upper surface of the block guide 65 and the upper surface of the flush piston 68 that are engaged with the upper inner side surface of the flush cylinder 61 so that both ends thereof abut against each other to provide an elastic force against the flush piston 68 It plays a role.

As described above with respect to the operation of the toilet 10 when the insertion amount of the pedal 40 does not reach the threshold value, the flushing block 62 is raised only to the extent that the flushing block 62 does not reach the limiter 66, There is no influence on the rod 67 and the flush piston 68. [ Therefore, the washing water can not be moved.

9, the plush block 62 contacts the limiter 66 and pushes the limiter 66 upward, so that the piston rod connected to the limiter 66 The piston 67 starts to rise, and the flush piston 68 connected to the piston rod 67 starts to rise. Also, while the flush spring 69 begins to be compressed, it begins to apply the elastic force to the flush piston 68 downward.

The flush piston 68 ascends and separates from the connecting portion between the inflow portion 64 serving as the passage for the washing water and the washing water pipe 63 so that the washing water starts to move from the inflow portion 64 to the washing water pipe 63 do. Therefore, the washing water is supplied through the washing water pipe 63 to supply the washing water to the toilet bowl 20 through the washing water supplying portion 23.

The amount of rotation transmitted to the links 41, 42, 43, 44, and 45 is changed depending on how much the pedal 40 is inserted even when the amount of the pedal 40 inserted exceeds the threshold, ) Rise in height. Therefore, the supply amount of the washing water is adjusted in accordance with the amount of the pedal 40 sucked.

An elastic force is applied to the valve closing piston 51 by an elastic member existing in the valve closing portions 50 and 51 to release the valve closing piston 51 from the pedal 40, The flush piston 68 and the link 41, 42, 43, 44, 45 and the pedal 40 are originally pushed by the flushing spring 69 in the downward direction, Return to position. The drain hinge 32 also returns to its original position and the drain valve 30 again blocks the point where the toilet bowl 20 and the drain pipe 31 meet and the flush piston 68 is again connected to the inlet 64 and the washing water pipe (63) to block the inflow of the washing water. At this time, the volume of the washing water ultimately supplied by the opening of the point at which the inflow part 64 and the washing water pipe 63 meet each other can be a maximum of 5 liters.

The structure of the flush portion 60 is such that the flush spring 69 is disposed above the flush piston 68 and the guide block 65 is provided to move the flush block 62 up and down. But is not limited to, a configuration in which a spring is disposed in the flush piston 68 to cause a tension when the flush piston 68 is moved upward to provide an elastic force to the flush piston 68, A variety of configurations can be used as a component of the flush portion 60 if the configuration can perform the same purpose.

The flushing cylinder 61 and the valve closing cylinder 50 may be filled with liquid or the like for buffering, so that the process of returning the components of the toilet 10 described above to the original state can be performed more slowly.

Therefore, when the amount of the pedal 40 to be inserted exceeds the threshold value, the drain valve 30 can be opened and the washing water can be supplied, and the amount of opening and the amount of washing water supplied can be controlled by adjusting the amount of the pedal.

FIG. 12 is a graph showing the relationship between the answer amount x in the operation of the toilet according to an embodiment of the present invention and the force (f) required to step on the pedal 40. FIG.

When the amount of the input x of the pedal 40 and the force f of pressing the pedal 40 are x and y axes respectively, The force (f) to step on tends to increase monotonously. This is because the greatest portion of the resistance element is occupied by the elastic force provided by the valve closing portions 50 and 51 or the flush spring 69. [ Since there is no action of the flushing section 60 before the amount of the answer reaches the threshold value C, only the elastic force by the valve closing portions 50 and 51 acts, and the angle formed by the graph on the x-axis is represented by a. However, when the insertion amount x reaches the threshold value C, the elastic force by the flush spring 69 is added as a resistance element. Therefore, the force (f) for depressing the pedal 40 at this point increases discontinuously, and the inclination of the graph also becomes large. The angle formed by the graph after the threshold value (C) with the x axis is represented by b, and the relationship of b> a is established. Here the slope of the graph is the stiffness of the entire toilet. Therefore, the user can easily recognize that the force required to press the pedal rises sharply without visually determining whether the answer amount x has reached the threshold value C, and it is easy to determine whether or not the water is to be lowered .
