The present invention relates to a toilet having an injection pump and a rim-side water supply apparatus using the same, and more particularly, to a toilet having a spray pump and a rim-side water supply apparatus using the same to stabilize the water pressure and supply the quantitative washing water.

The toilet consists of a water tank installed at the bottom of the water tank and the water storage tank receiving and storing the washing water through the ball tap, and the water is discharged to the water tank main body when the water stopper is opened by the operation lever installed in the water tank. It is structured to be discharged. These toilets can be classified into two-piece toilets in which the reservoir and the toilet body are separated, and one-piece toilets in which the reservoir and the toilet body are integrally formed. One-piece toilets, one-piece toilets, are widely used.

Reservoir integrated toilet is structured to discharge the water stored in the reservoir to clean the toilet body and to send the water supply from the water supply pipe directly to the rim. The normal level of the reservoir is lower than the rim channel, so the rim cleaning power is very low. . The reason is that the water stored in the reservoir cannot be sent to the higher rim channel, so the water supply from the water pipe is sent directly to the rim because the flow rate is too small.

Therefore, the present applicant in the Republic of Korea Patent Application No. 10-2004-29870 to supply the mixed rinsing water combined with the water supplied from the water supply pipe and the washing water in the reservoir through the injection pump between the ball tap and the rim channel of the water tank integrated toilet bowl to the rim channel A toilet including a injection pump has been disclosed.

1 is a cross-sectional view showing a toilet having a rim-side water supply device using the injection pump disclosed by the applicant, Figure 2 is a cross-sectional view showing the inside of the reservoir of the toilet.

1 and 2, a ball tap 117 is provided inside the reservoir 110 to supply water from the external water supply pipe 107. A ball 133 is connected to the ball tab 117, and has a switching unit 118 for switching the water supply to the reservoir and the rim side. When the user operates the operation lever 112 to clean the toilet, the water stopper 113 connected to the operation lever 112 is rotated upward to open the jet channel 129 of the reservoir 110, The washing water discharged to the jet channel 129 is discharged to the jet nozzle 127 to wash the toilet and at the same time the washing water is discharged to the discharge hole 125 of the rim through the ball tab 117, the toilet body 119 Clean the remaining stool in the cleaning space of the.

An injection pump 150 is interposed between the rim side connecting pipe 120 and the rim channel 123 of the ball tab 117. When water is drained through the water stopper 113, water is supplied to the ball tab 117, and at this time, water is started to the rim-side connecting pipe 120 connected to the ball tab 117, so that the injection pump 150 is operated so that the rim channel 123 is operated. It is supplied with a mixed washing water combined with the water supplied from the ball tap and the washing water in the reservoir tank, the rim cleaning is effectively carried out.

When all the washing water in the reservoir 110 is discharged, the water stopper 113 is rotated downward by the magnetic force to block the jet water channel 129 of the reservoir. At this time, the external water supply is switched to the reservoir tank supply pipe 131 through the switching unit 118 of the ball tap 117 to store the washing water in the reservoir 110, the injection pump 150 is stopped. When the water in the reservoir 110 reaches a certain level, the ball tap 117 blocks the water supply to the reservoir 110 by the action of the buckle 133 and waits for the next operation.

Rim cleaning power is excellent because the mixed rinsing water consisting of the washing water stored in the reservoir 110 and the water supplied from the ball tap 117 is supplied to the rim by the injection pump 150 having the water supply device using the above-described injection pump Has However, the water pressure of the water supply supplied to the injection pump 150 is largely varied depending on the situation depending on the installation area, use time, etc. of the toilet, so that the change in the water supply flow rate is large and consequently the washing water supplied to the rim channel 123. The width of the change is also large, there is a disadvantage that the water consumption increases rapidly when the supplied water supply is high water pressure. In order to compensate for this, an expensive constant flow rate valve may be installed in the water supply pipe, but there is a problem in that the washing power is lowered due to an increase in installation cost and a loss of water pressure in a low water pressure state.

In addition, after the operation of the injection pump 150 is stopped, the connection pipe and the rim channel 123 of the injection pump are filled with the remaining washing water. At this time, the residual washing water flows out into the discharge hole 125 of the rim without flowing down through the connecting pipe to the reservoir with the low water level. This is because the discharge hole 125 of the rim is about 4mm in diameter and the surface tension is affected, the kinetic energy during the operation of the injection pump acts to gradually drain the residual washing water into the discharge hole 125 of the rim. As the residual washing water flows out into the discharge hole 125 of the rim, the level of the washing water in the reservoir is lowered to be lower than the normal water level, so that the ball tap 117 for opening and closing the water supply malfunctions. In order to compensate for this, a vacuum brake may be introduced into the rim connection line, but in this case, the structure of the toilet may be complicated, expensive, and water pressure loss may occur, resulting in a reduction in the washing water.

An injection pump 250 according to the first embodiment of the present invention is interposed between the 223 and the rim side connecting pipe 220 of the ball tab 227. The injection pump 250 is branched from the suction pipe 221 of the injection pump to the supply pipe 222 and the control pipe 263, the pressure control unit 270 is connected to the branched control pipe 263. The pressure control unit 270 has a constant water pressure by releasing a part of the supply water through the outlet 272 into the reservoir 210 when the pressure of the feed water supplied through the suction pipe 221 of the injection pump is high. Is supplied to the rim channel 223.

Referring to FIG. 4 again, an injection pump 250 is interposed between the ball tap connector pipe 220 and the rim channel 223, and the injection pump 250 is a supply pipe 222 branched from the suction pipe 221 and the suction pipe. ) And a control tube 263, the injection nozzle 251, the throat 255, and the expansion tube 257 and the rim connecting portion 260 between the supply pipe 222 and the rim channel 223, An inlet 253 is formed between the injection nozzle 251 and the throat 255 through the outside. The pressure control unit 270 is connected to the control pipe 263 branched from the suction pipe 221. The pressure control unit 270 is provided with an elastic force to the opening and closing plate 274 and the opening and closing plate 274 opening and closing the outlet 272 and the outlet 272 through the outside to the hydraulic pressure of the suction pipe 221 Therefore, it is comprised by the elastic body 275 which controls opening and closing of the outlet port 272.

Hereinafter, the operation principle of the rim-side water supply device using the injection pump according to the first embodiment of the present invention.

5A and 5B are cross-sectional views showing the operating principle of the rim-side water supply device using the injection pump according to the first embodiment of the present invention.

Referring to FIG. 5A, when the user starts the washing operation with the operation lever, the discharge of the washing water is started with the water stopper. As the water supply starts from the ball tap to the suction pipe 221 of the injection pump through the ball tap connecting pipe 220, the injection pump 250 is operated to feed the water (Qin) and the suction flow rate Qs, which is the washing water in the reservoir to the rim channel 223. ) Is supplied with the discharge flow rate Qd which is the mixed washing water. When the pressure of the water supply flow rate Qin supplied to the suction pipe 221 is appropriate, the opening / closing plate 274 maintains an initial state of blocking the outlet port 272 to discharge water flow rate Qd through the injection pump. Water is supplied to this rim channel 223.

Referring to FIG. 5B, when the pressure of the supply water supplied from the external water supply pipe is high or the water pressure increases irregularly due to other factors, the water supply flow rate supplied to the suction pipe 221 through the ball tap connection pipe 220 ( The pressure of Qin) may be uneven or high. At this time, while the elastic body 275 contracts by the pressure of the water supply flow rate Qin, the opening and closing plate 274 retreats to open the outlet 272. As the outlet 272 is opened and a portion of the feed water Qe is discharged, the internal pressure of the supply pipe 222 branched from the suction pipe 221 is lowered. The elastic body 275 contracts or expands in accordance with the pressure of the supply water, thereby discharging the appropriate amount of the supply water into the water storage tank, thereby keeping the injection flow rate Qj into the supply pipe 22 constant. That is, the injection flow rate Qj of the quantity excluding the discharge flow rate Qe from the water supply flow rate Qin is provided to the supply pipe 222, and the discharge flow rate Qd of the washing water supplied to the rim channel 223 is supplied to the supply pipe ( The mixed washing water, in which the injection flow rate Qj supplied from 222 is added to the suction flow rate Qs by the operation of the jet pump, is supplied.

Meanwhile, when the injection pump is operated as shown in FIGS. 5A and 5B, a part of the mixed washing water is discharged to the reservoir through the vent through the vents 280 and 280a. This may be determined to result in a decrease in the flow rate of the mixed washing water supplied to the rim channel 223, but in practice, the flow rate of the mixed washing water does not decrease. The reason for this is that the discharge flow rate of the injection pump is partially reduced due to the hydraulic pressure loss occurring in the connecting pipe and the rim channel after the expansion pipe 257 of the injection pump. This is because the discharge flow rate of the injection pump increases.
