Definitions

• the present invention relates to an automatic water flush toilet which does not need a water reservoir and a siphon, a bowl tap, and a lever included therein to reduce production cost, has no troublesome parts to improve durability, takes up less space, and uses a small amount of water which is compressed and injected by high pressure compressed air.
• a large water reservoir takes a large amount of space and includes a siphon, a bowl tap, and a lever, which frequently causes the water flush toilet to malfunction. Also, as water always remains in the bowl of the toilet, water may splash and embarrassing or unpleasant sounds are made when the toilet is used. Further, as water of low pressure in the water reservoir is used to clean the bowl, as much water as about 13 liters is consumed per flush. It is also inconvenient to manually operate the lever for flush.
• a water flush toilet using a flash valve adopts a 25 mm water pipe.
• a 15 mm water pipe is used, as the water reservoir should be installed at a higher position, installation cost increases and much more water is consumed.
• an automatic water flush toilet which does not required a water reservoir and a siphon, a bowl tap, and a lever thereby saving production cost, has no troublesome parts to improve durability, takes up less space, and uses a small amount of water which is compressed and injected by high pressure compressed air.
• an automatic water flush toilet comprising: a bowl having a compression chamber inside, the compression chamber being equipped with a bolt pipe and a water supply pipe at the upper and lower portions thereof, respectively; an elbow coupled to the bolt pipe of the bowl; an outlet pipe coupled to the end portion of the elbow and having an indentation; a valve included in the outlet pipe and elastically supported to be capable of moving forward and backward; a lever installed inside the indentation of the outlet pipe; and a shaft fixed to the lever by passing through the lever.

• the vertical pipe portion of the elbow 32 around which a big nut 64 and an O-ring 33 are inserted is inserted into the bolt pipe 63 and screw- coupled such that a space for flowing water is generated between the lower portion of the vertical pipe portion of the elbow 32 and the bottom surface of the compression chamber 9.
• the horizontal portion of the bent shafts 28 and 29 are inserted into holes of a toilet seat 66 and a toilet seat cover 67.
• the vertical portion of the bent shaft 28 is coupled to the arm 21 by a shaft 30 inserted into a hole 70 formed in the bent shaft 28, and the vertical portion of the bent shaft 29 is coupled to the arm 22 by a shaft 31 inserted into a hole 70 formed in the bent shaft 29.
• the lower portions of the vertical portions of the bent shafts 28 and 29 are fixed on the leaf springs 35 and 35' to thus be elastically supported.
• FIG. 2B shows an automatic water flush toilet having a structure similar to that shown in FIG. 2A, in which a fluid decelerating portion is coupled to the upper end of the elbow 32 of the automatic opening/shutting portion.
• a chamber 56 in the cylinder 42 which is partitioned by a wall having holes 57 and 68 for connection at the upper and lower portions of the wall, respectively, is filled with fluid.

• FIGS. 2C and 2D show the automatic opening/shutting portions including the outlet pipe 1 which are vertically structured.
• the shaft supporter 17of the lever 14, the shaft 18, and the roller 19 is removed, and in FIG. 2D, the internal structure of the outlet pipe 1 is opposite to the direction of that of FIG. 2C including the shaft support 17 of the lever 14, the shaft 18, and the roller 19.
• the water supply pipe 10 is connected to a water service pipe and water is supplied to the compression chamber 9.
• water supplied increases from the lower portion of the compression chamber 9
• air in the upper portion thereof is compressed until the pressure of the air becomes the same as that of the water.
• the supply of water is shut off and the compression chamber 9 is filled with high- pressure air and water.
• the lever 14 rotates counterclockwise and, as the roller 19 contacts the rod 6, the rod 6 is pressed downward and the valve 5 is released to allow water to flow into the bowl 38.
• the amount of water flowing through the outlet hole 2 of the outlet pipe 1 increases as the rotation speed of the lever 14 decreases.
• the person should adjust the speed of sitting down on and getting up from the toilet. If the person sits or gets up quickly, only a small amount of water flows in.
• the push frame 37 When a female urinates, the push frame 37 is pushed forward to rotate clockwise around the shaft 72 and the support bar 71 is placed on the bowl cover 40 and support the bent shafts 28 and 29. Thus, if she sits on the toilet seat 66, since the bent shafts 28 and 29 and the toilet seat 66 are not pressed down, water does not come out. After she finishes her needs in the above state, the push rod 37 is pushed backward to rotate counterclockwise and the urine can be cleaned with a small amount of water as described in the male case.
• the bolt 50 is rotated in the screw-coupling direction. Then, the bolt 50 pushes the ball 48 toward the side of the hole 68 having a larger diameter and the speed of the fluid passing through the hole 68 increases. Accordingly, the piston 43, the push rod 44, and the lever 41 return to their initial positions faster and the valve 5 is closed faster so that the a small amount of water flows in.
• the siphon, the bowl tap, and the lever of the water reservoir are not required, manufacturing cost is reduced with low possibility of malfunction and decreased installation space. Also, since water does not remaining in the lower portion of the bowl, there is no splashing and embarrassing or unpleasant sounds are made. Further, since the bottom surface is wet with a small amount of water before one urinates or defecates, cleaning is facilitated. Furthermore, since water of high pressure is injected by air compressed by the pressure of the water supplied through a narrow water service pipe, cleaning with a small amount of water is possible.
