Description

Variable double straight tube water saving toilet

The present invention relates to a variable double straight tubular water-saving toilet, and more particularly, to a variable double straight tubular water-saving toilet to naturally discharge dirt from the bowl by the inclination angle of the variable double straight pipe connected to the outlet of the toilet bowl and bellows. will be.

In general, a toilet siphon (siphon) is used to store a certain amount of water in the potty for smooth cleaning of the odor or manure coming from the manure discharge.

This siphon principle is that when the water level in the inverted U-tube and the water level in the toilet are in equilibrium, the water is stagnant, but when the water level in the toilet suddenly rises, the pressure in the toilet is accompanied by a pressure rise in the relatively low pressure siphon tube. It is a principle that water in toilet is discharged by car.

Recently, as the water shortage has arrived, the fixed siphon principle requires a lot of washing water, so that a water-saving toilet of a variable siphon method has been invented.

The existing configuration of the variable siphon tube driving device of the toilet is connected to the manure drainage pipe of the bowl via a bellows tube, and is inverted U-shaped variable siphon tube, and the bowl is connected to the water supply passage and at the same time the variable siphon via the auxiliary pipe. A water bag in communication with the tube; The variable siphon tube is lowered by the water level rise in the bowl and the weight of the water introduced into the water bag, and then the water bag and the variable siphon tube are restored to the original state after the water in the bowl is discharged through the manure discharge pipe.

As an example of the restoring means, a flexible guide bar 101, a roller 103 provided on the guide bar 101 and seated on a lower portion of the variable siphon tube 102, and water in the bowl 104. After the discharge through the manure discharge pipe 105 there is a form consisting of a recovery spring 107 to restore the water bag 106 to the original state by restoring the variable siphon tube 102 to its original state, 1 is shown.

The variable siphon tube driving apparatus of the toilet having the above-mentioned restoring means is not smoothly restored due to entanglement while the restoring spring 107 is operated, and thus the variable siphon tube even after all the water in the water bag 106 is discharged ( Occurrence of an operation error in which the 102 does not rise to its original state, difficulty in installing the guide bar 101, and the installation wall surface W when the bent end 102a of the variable siphon tube 102 in the inverted U shape rotates. There is a problem such as difficulty in slimming down the toilet according to lengthening the rear portion of the bowl 104 sufficiently to avoid being disturbed.

Patent Registration No. 10-479678 (name of the invention: variable siphon tube driving device of the toilet) has been disclosed to improve the problem of the restoration means, which is shown in FIG.

Variable toilet siphon driving device of the toilet bowl is tightening ring 201 is fastened to the coupling neck of the water supply passage; A bracket 204 coupled to the bottom surface of the water bag 202 and hinged to the variable siphon tube 203; After connecting the tightening ring 201 and the bracket 204, the water in the bowl 205 is discharged through the manure discharge pipe 206, and then the variable siphon pipe 203 and the water bag 202 are restored to their original state. It is composed of a restoring spring (207).

In the variable siphon tube driving device of the toilet, the variable siphon tube 203 is U-shaped and has a long length and is connected by the bottom tube and the lower corrugated tube 208, so that the restoring spring 207 uses a tension spring having a large elastic force. The capacity of the water bag 202 is increased according to the use of a tension spring having a large elastic force, and the amount of water injected into the bowl 205 is relatively low according to the use of the large-capacity water bag 202. The lower corrugated pipe 208 has a problem in that the life of the variable siphon tube 203 is reduced by contact with the bottom surface.

Patent Registration No. 10-714961 (name of the invention: variable manure discharge system of the toilet) has been disclosed to improve this problem, which is shown in FIG.

The variable manure discharge system of the toilet bowl has a stretchable water bag 303 is installed to be connected to the water supply passage 302 of the tank at the rear of the bowl 301, and the elastic force to shrink the water bag 303 While exerting the tension spring 304 to be exerted, and by the expansion and contraction movement of the water bag 303 while being connected via the water bag 303 and the bracket 304, the dirt in the bowl 301 is discharged. A variable discharge pipe 305 is connected to the outlet of the 301 and the corrugated pipe 306 in the form of a straight tube, and the micro-pipe 307 connecting the water bag 303 and the variable discharge pipe 305 Is done.

In addition, the variable manure drainage system of the toilet includes a housing 308 composed of a combination of a first housing 308a surrounding a part of the system and a second housing 308b surrounding the other outer part as shown in FIG. 4. Equipped.

At this time, the variable discharge pipe 305 is one end is installed in communication with the bowl 301, the other end is installed in communication with the interior of the housing 308, the tension spring 304 is the water bag ( 303, the upper end is fixed to the upper hanger 302b installed in the outlet 302a of the water supply passage 302, the lower end is provided on the bottom surface or bracket 304 of the water bag 303 It is fixedly installed to the lower hanger 304a.

The variable manure drainage system of the toilet uses a variable straight tube to significantly reduce the size of the U-shaped variable siphon tube to reduce the elastic force of the tension spring 304, and to reduce the capacity of the water bag 303, and relatively The amount of water introduced into the bowl 301 is increased, and the durability is improved by removing the lower corrugated pipe whose life is shortened by contact with the bottom surface during the downward movement of the variable siphon tube.

The variable manure discharge system of the toilet has the following problems in spite of these advantages.

First, the amount of operating water used in the water bag is large, the washing efficiency is lowered.

The system is similar to a conventional U-shaped variable siphon tube. The bracket 304 is caught on the hook portion 305a of the variable discharge tube 305 (the conventional U-shaped variable siphon tube corresponds to the bent portion). Connected with Accordingly, in order to discharge the dirt in the bowl 301, the variable discharge pipe 305 must be sufficiently lowered. In order to sufficiently descend the variable discharge pipe 305 as described above, the vertical displacement of the water bag 303 connected to the bracket 304 should be large. The greater the amount of vertical displacement of the water bag 303, the longer the length of the water bag 10, the longer the length of the water bag 303 will result in an increase in the capacity of the water bag 303, thereby changing the variable discharge pipe 305 In order to lower the amount of the operating water is injected into the water bag 303 is also increased.

Therefore, in the case of using a large-capacity water bag 303, the elastic force of the tension spring 304 necessary for contraction of the water bag 303 as well as an increase in the material cost of the water bag itself should be large. Therefore, an expensive tension spring 304 should be used. There are disadvantages.

More seriously, some of the water discharged from the water tank is introduced into the water bag 303 and used as the operating water for operating the water bag, and the remaining water is introduced into the bowl 301 to be used as the inner washing water of the bowl. When the amount of the operating water flowing into the 303 increases, the amount of water flowing into the bowl 301 is relatively reduced, so that the washing effect inside the bowl 301 is lowered.

Second, there is a problem in the efficiency of the installation work of the water bag 303 and the tension spring 304 in the water bag 303.

The system uses a water bag 303 as with a conventional U-shaped variable siphon tube.

The water bag 303 is essentially installed for the vertical operation of the variable discharge pipe 305, in order to install the water bag 303, the outlet 302a and the water bag 303 of the water supply passage 302. ) The upper and lower fastening rings for watertight bracket 304 and the water bag 303 attaching surface should be used, but the work efficiency is inferior, and the tension spring 304 is mounted inside the water bag 303. The upper end of the) is fixed to the upper hanger 302b installed in the outlet 302a of the water supply passage 302, and the lower end is fixed to the lower hanger 304a provided on the bottom bottom surface of the water bag 303. Due to the space constraints of the toilet, there is a difficulty in assembling, which also causes many problems in the efficiency of the work.

Third, there is a difficulty in assembling the microtubes (108 of FIG. 1, 307 of FIG. 3).

When installing the micro pipe 307 connecting the water bag 303 and the variable discharge pipe 305, there is a difficulty in assembling due to the spatial constraints of the toilet bowl, which reduces work efficiency.

Fourth, the assembly work efficiency of the housing is lowered.

The housing 308 should be fully sealed to prevent odors that flow back from the bottom tube 309. To this end, the top and bottom of the housing 308 should be completely sealed.

Therefore, the housing 308, the outside of the telescopic water bag 303 is installed to be connected to the water supply passage 302 in the rear of the bowl 301, the upper portion of the housing 308, the bowl 301 The coupling portion of the housing 308 made of a combination of the water outlet outside, the first housing 308a surrounding a part of the variable manure drainage system of the toilet and the second housing 308b surrounding the remaining outside, and the housing ( 308) It must be assembled to the bottom tube 309, which is the lower part of the assembly. In general, due to the manufacturing characteristics of the toilet bowl made of porcelain, the assembly position is often not accurate, which causes difficulty in assembling, thereby significantly lowering productivity and ensuring quality stability. There is also a problem.

Fifth, the return time of the variable discharge pipe 305 after the waste discharge is delayed.

In order for the variable discharge pipe 305 to return to the state before the discharge after the discharge of the waste, the water in the water bag 303 is discharged into the variable discharge pipe 305 through the micro-pipe 307 and the tension spring 304 With the restoring force of the water bag 303 should be made to contraction. The diameter of the microtube 307 is relatively small, so that the time taken for the operating water in the water bag 303 to be discharged through the microtube 307 to the variable discharge pipe 305 is delayed. Due to this delay, even if the operating water in the water bag 303 is discharged to the variable discharge pipe 305 until the hook portion 305a of the variable discharge pipe 305 is moved upward, the water cannot be introduced into the bowl 301. It is discharged as it is, there is a problem that leads to waste of the operating water.

The present invention has been made in order to solve the above problems, an object of the present invention, to improve the washing efficiency of the bowl by allowing the entire amount of the washing water flowing into the water bag to be introduced into the bowl without using the water bag. To provide a variable double straight tubular water-saving toilet.

The variable double straight pipe 20 having such a configuration is installed higher than the water level of the wash water accommodated in the bowl 11 as shown in FIG. In this case, the washing water contained in the bowl 11 does not overflow the inner tube 21 and the inflow of the washing water into the accommodation space 23a is prevented.

In this state, when the washing water is introduced into the bowl 11 to discharge the dirt, the other end of the inner tube 21 is lower than the washing water level in the bowl 11 due to the increase of the washing water introduced as shown in FIG. 11. do.

Therefore, it is possible to reduce material costs and improve assembly and reliability.

In addition, most of the washing water and dirt is discharged from the inner tube 21 to the cover portion 14 due to the high discharge pressure during the discharge of the washing water and dirt in the bowl (11), but the discharge pressure of the washing water and dirt is low At the end, just before the variable double straight tube 20 is rotated upward, the washing water and dirt discharged from the bowl 11 through the inner tube 21 are not moved to the cover portion 14 and the inner tube ( Since it falls to the outer tube 22 provided outside the 21, some of the washing water and dirt at the time of the upper rotation of the variable double straight tube 20 remains inside the receiving space (23a). When the wash water and the dirt remain in the receiving space (23a) as described above affects the elastic restoring force of the tension spring 40 during the upper rotation of the variable double straight tube 20 by the elastic restoring force of the tension spring (40) This impedes the upper rotation of the variable double straight pipe (20). Accordingly, the return time is increased by the upper rotation of the variable double straight pipe 20, and the lower rotation time of the variable double straight pipe 20 becomes faster when the next washing water and the dirt are discharged, thereby reducing the washing efficiency. There is this.

Therefore, a part of the washing water and the dirt remaining in the accommodation space 23a during the upper rotation of the variable double straight pipe 20 should be discharged. To this end, as shown in FIGS. 7 and 9, the connection part 23 disposed below the inner tube 21 is disposed after the washing water and the dirt are discharged in the bowl 11 by the lower pivot of the variable double straight tube 20.
