The first, this controlled-length apparatus is used to adjust the water level of water jet pump;
The position that is arranged on the water jet pump in the water tank depends on the size of toilet or the form of water-closet tank.Simultaneously, because the position difference of water jet pump (or hydraulic pressure or water yield difference of water jet pump supply) is discharged to flushing water flow velocity that sprays the water pipe side and the ratio that is discharged to the flushing water flow velocity of edge side and changes in flushing operation, thereby changed flushable property.This is because the part that is stored in the flushing water in the water tank is sent to edge side by the operation of water jet pump.In order to improve flushable property and to reduce water loss, must be based on the shape and the aforementioned ratio of structural adjustment of toilet.Therefore, the invention provides controlled-length apparatus, it is used to determine to be discharged to flushing water flow velocity that sprays the water pipe side and the ratio that is discharged to the flushing water flow velocity of edge side.
The second, controlled-length apparatus is used to deal with the variation of toilet size.
The toilet size can change on a large scale in manufacture process.Therefore, even toilet has same shape and structure, according to the composition ratio or the stove sintering temperature of material, the dimensional errors in the product is very big.Like this, the water level deviation in water jet pump becomes very big, thereby the flushable property variation of water jet pump.Therefore, the invention provides controlled-length apparatus, be used to consider that the dimensional errors of toilet product is provided with the water level of water jet pump.
Equally, require suitable fixed cell to keep controlled length.In the present invention, projection and hook are formed at the lap periphery inner surface and the external surface of pipeline respectively.Like this, when hook is lifted gently or mentioned by very big strength and be sent to next projection by an inclined surface, this length is controlled.
Figure 22 is the cross section view of the toilet of use water jet pump shown in Figure 4.
With reference to Figure 22, when user's operating operation lever 212 flushing excretas, the valve plug 213 that is connected to operating lever 212 rotates up, and opens the injection water pipe 229 of water tank 209.Like this, being discharged to the flushing water that sprays water pipe 229 is drained with the flushing excreta by nozzle.Simultaneously, flushing water is discharged to edge drainage hole 225 remains in the flushing space of closestool body 219 with flushing excreta by ball valve 227.Water jet pump 250 places between ball valve 227 and the edge water pipe 223 will supply water and mixes with the flushing water that is stored in water tank 209 and be fed to edge water pipe 223.
If flushing operation is finished, valve plug 213 is rotated down owing to its moment, to turn-off the injection water pipe 229 of water tank 209.Equally, the washing water quantity that water tank 209 is storing predetermined is waited for operation next time.
By using above-mentioned water jet pump 250, water supply installation shows excellent flushable property because be stored in the flushing water in the water tank 209 and mix from the supply water of ball valve 217 after be provided to the edge.But, variation according to circumstances, supply water changes on a large scale at one the pressure of water jet pump 250, the zone of installing as toilet or the time of toilet use.As a result, the variation that is fed to the flushing water of edge water pipe 223 becomes very big, and water consumption increases sharply under high hydraulic pressure.For alleviating this problem, a kind of flow control valve of high price can be installed on the feed pipe, but the installation cost increase, and bring in the pressure loss of hanging down under the hydraulic pressure, so just reduced the flushable property of toilet.
In addition, after water jet pump 250 work were finished, the tube connector of water jet pump 250 and edge water pipe 223 were full of by remaining flushing water.In this case, remaining flushing water is not the water tank that flows to low water stage by tube connector, but discharges by edge drainage hole 225.Be about 4 millimeters because the diameter in edge drainage hole 225 is less, its effect of surface tension flushing water.Equally, the kinetic energy that causes at work of water jet pump 250 acts on the flushing water.Like this, remaining flushing water is discharged from by edge drainage hole 225.At this moment, the water level of the flushing water in the water tank 209 reduces, thereby the ball valve 216 that is used to supply water may break down.For preventing that fault from taking place, easamatic power brake can be introduced the tube connector at edge, but toilet structure is complicated and expensive like this, and is produced the minimizing of flushing water by the pressure loss.
Therefore, the invention provides a kind of pressure control unit, it is installed on the water jet pump that is connected to the bowl rim water pipe.Like this, the water that is fed to water jet pump can keep constant, requires the water yield at flushing edge also to keep constant.
Further, in the present invention, gravity vent is formed at the edge connection portion of water jet pump, or on the combination position between edge connection portion and the edge water pipe, the feasible flushing water that remains in water jet pump tube connector and the edge water pipe can be discharged by water tank and edge drainage hole rapidly after water jet pump work.
Below, comprise that according to the embodiment of water jet pump of the present invention pressure control unit and gravity vent will be described.
Embodiment 4:
In the present embodiment, water jet pump is connected to have and is used to change the ball valve that water flows to the commutation part at water tank or edge.
