Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The servicing unit enclosing and wash away washed by a kind of lower water box as shown in Figure 1 and Figure 2, be arranged in water-closet tank, comprise water inlet pipe 10, outlet pipe 17, water inlet pipe 10 one end is water inlet 11, water inlet pipe 10 other end is nozzle 12, water inlet 11 higher than nozzle 12, for the current that will enter from water inlet 11 under the effect of potential energy, be converted into the kinetic energy of the current ejected from nozzle 12, make the current ejected obtain certain speed; The jet 13 of nozzle 12 is less than water inlet 11, in the present embodiment, the inner chamber of nozzle 12 reduces gradually, by less jet 13, water flow jet is gone out, superpressure district is formed in nozzle 12 before the jet 13 of nozzle 12 end, improve the hydraulic pressure in water inlet pipe 10, sharply increase with the flow velocity realizing jet 13, current obtain higher jet velocity.
Outlet pipe 17 end is delivery port 18, and delivery port 18 is higher than water inlet 11, and outlet pipe 17 other end arranges receiving chamber 14, nozzle 12 is set in receiving chamber 14, fluid-mixing sprays from nozzle 12, by receiving chamber 14 to delivery port 18 successively through mixing, diffusion, then flows out from delivery port 18.In the present embodiment, between receiving chamber 14 to delivery port 18, be disposed with mixing chamber 15, diffuser casing 16; The water ejected from nozzle 12 forms negative pressure at mixing chamber 15, and carries out momentum-exchange with the water entered from water sucking mouth 20, forms flowing velocity distribution uniform current gradually, through diffuser casing 16 diffusion, flows out from delivery port 18.
In order to improve discharge, receiving chamber 14 is communicated with lower water box by water sucking mouth 20, and when the water that nozzle 12 ejects forms negative pressure at mixing chamber 15, the water of lower water box is sucked mixing chamber 15 by water sucking mouth 20 by negative pressure.
In order to improve the aspiration rates of the water to lower water box, in the present embodiment, receiving chamber 14 is set to horn-like, covers at outside nozzle 12, and jet 13 exists distance with the bottom of trumpet-shaped receiving chamber 14, is convenient to form negative pressure.
Nozzle 12 is arranged towards diagonal upward direction, and jet 13 is relative with the bottom of trumpet-shaped receiving chamber 14.Nozzle 12 is directly aimed at mixing chamber 15, reduces the shock of current and receiving chamber 14 as far as possible and cause slowing down of water velocity, and on the impact that negative pressure is formed, and then reduce the extraction yield of water sucking mouth 20.
Mixing chamber 15 is the cylindrical structure longitudinally arranged, and receiving chamber 14, diffuser casing 16 are communicated with going to the bottom with the upper base of cylindrical structure respectively.The current that cylindrical structure is conducive to ejecting from nozzle 12 form enough negative pressure in mixing chamber 15, contribute to the suction of the water of lower water box to be used for washing circle.
The internal diameter of diffuser casing 16 increases from the front end connecting mixing chamber 15 gradually to the end connecting delivery port 18, carries out diffusion, form stable current for the water flowed out by mixing chamber 15.
Be provided with the transfer strip 19 be rotationally connected in mixing chamber 15, transfer strip 19 carries out displacement along the radial direction of mixing chamber 15.As shown in Figure 3, when transfer strip 19 turns to the link position of diffuser casing 16 and mixing chamber 15, diffuser casing 16 and mixing chamber 15 end.This state is the state at the end of draining, and residue current flow into lower water box from water sucking mouth 20.As shown in Figure 2, when transfer strip 19 turns in mixing chamber 15, diffuser casing 16 is communicated with mixing chamber 15.This state is draining original state or water inlet state, and water flows into from water inlet 11, after nozzle 12 ejects, successively by receiving chamber 14, mixing chamber 15, diffuser casing 16, finally flows out from delivery port 18.
The present embodiment is in conjunction with closestool water inlet valve and delivery port 18 size, as shown in Figure 4: the water inlet 11 diameter D1 of injector is 11mm, delivery port 18 diameter D2 is 22mm, nozzle 12 is 90mm to the vertical height H of delivery port 18, in conjunction with this size, all the other sizes of injector are optimized, specific as follows:
Jet 13 diameter D3 value need be less than water inlet 11 diameter D1, span 2 ~ 6mm.When size is less than 2mm, under the condition for given water inlet pipe water feeding pressure, the mass flow that nozzle 12 place can reach is limited, and can form certain superpressure in nozzle 12, now comparatively tight to the requirement of product strength and sealing, is unfavorable for producing; When given mass flow, D3 is less for jet 13 diameter, and suction effect is better.When jet 13 diameter D3 diameter is 9mm, multiplying power μ=2 of delivery port 18 water yield and water inlet 11 water yield; When jet 13 diameter D3 diameter is 7mm, multiplying power μ=3 of delivery port 18 water yield and water inlet 11 water yield, when jet 13 diameter D3 diameter is 4mm, multiplying power μ=6 of delivery port 18 water yield and water inlet 11 water yield.
The length L1 value 20 ~ 50mm of nozzle 12, when length L1 is longer, can reduce because nozzle 12 place reduces the local losses caused gradually, when length acquires a certain degree, effectiveness comparison is not remarkable.
When jet 13 arrives the length L2 value 5 ~ 20mm of receiving chamber 14 end, the high speed water that the water in lower water box can eject with nozzle 12 can carry out effective momentum-exchange.
As mixing chamber 15 diameter D4 value 10 ~ 15mm, length L3 value 20 ~ 50mm, mixing chamber 15 sections can form enough negative pressure, contributes to the suction of the water of lower water box to be used for washing circle.
Receiving chamber 14 is set to horn structure, the span of the angle α of horn structure 0 ~ 45 °, when angle α arranges unreasonable or cancellation receiving chamber 14, the pumping efficiency (injector outlet water quality flow and injector inlet water mass flow ratio) of injector will obviously decline.
Value 30 ~ 70mm after diffuser casing 16 length L4 optimizes.
Designing in conjunction with the value after above-mentioned optimization injector described in the utility model and test, when given water inlet mass flow, the pumping efficiency of test can reach 2.5 ~ 10; Even if in the lower situation of the water feeding pressure of water inlet pipe, still good suction effect can be obtained, abundant water is flowed to higher position from lower, then flows to toilet, meet and wash circle water supply volume.
Above-described embodiment is only used to the utility model is described, and is not used as restriction of the present utility model.As long as according to technical spirit of the present utility model, change above-described embodiment, modification etc. all will be dropped in the scope of claim of the present utility model.
