Abstract

The utility model relates to a jet-type water-saving toilet bowl with water and gas two-phase flow vortex, which utilizes injecting tap water to air to form gas and water two-phase flow and generate increasing current and pressurizing action, flat nozzles are arranged on different positions of the periphery of a bowl according to Archimedes spiral, the gas and water two-phase flow jets from the flat nozzles to flush the periphery of the bowl, thereby achieving water-saving effect of flushing. The jet-type water saving toilet bowl belonging to the field of sanitary wares comprises a back support, a movable cover plate, a bowl, flat nozzles, a feces hole, a drain trap, a gas injection pipe, a U-shaped horizontal connection pipe, a vortex shape two-phase flow water channel, a delay flushing valve, a seat of the toilet bowl, a drain pipe and a water inlet pipe. As pushing the delay flushing valve (or a self-inductance device) after the toilet is used, the water valve can automatic open for pluralities of seconds (capable of setting), then tap water is led in the vortex shape two-phase flow water channel via the U-shaped connection pipe and the gas injection pipe and jets from pluralities of the flat nozzles arranged on the periphery of the bowl to form the gas and water two-phase flow vortex, further feces is sucked in the feces hole and then drained to a sewer via the drain trap and the drain pipe, thereby achieving the purpose of water-saving flush.

Description

Air-water two phase flow vortex injecting type water-saving toilet pan

Technical field:

The title of the utility model patent is an air-water two phase flow vortex injecting type water-saving toilet pan, it by water closet backrest, water closet removable cover, bedpan, spiral type two phase flow water channel, flat nozzle, fall that just hole, trap, gas induction tunnel, the horizontal connecting tube of U type, delay flushing valve, water closet pedestal, blow-off pipe and water inlet interface are formed, play the effect of water saving flushing closestool, belong to the sanitation project field.

Background technology:

Most because the pressure head of water is low, irrigation flow rate is little with the flushing of water tank waters to water closet in the prior art, both wastes water (washing 6～8 liters of water consumptions) at every turn and is difficult for rinsing well, and ight soil is easy to be detained in trap; TOTO porcelain industry company has developed a kind of rotational flow flushing water closet that utilizes tap water pressure direct injection flushing recently, owing to have only a flush port, the washing area is limited, and only with the tap water flushing, water consumption is also big.

Goal of the invention:

In order to remedy above-mentioned deficiency of the prior art, the present invention will provide a kind of tap water injection air that utilizes to form air-water two phase flow, and produce incremental pressurization, from be arranged in the ejection of the flat nozzle on the diverse location around the bedpan by Archimedes spiral, play the effect of not only economizing on water but also water closet can be rinsed well.

Summary of the invention:

For reaching this purpose, the present invention should be by water closet backrest, water closet removable cover, bedpan, flat nozzle, fall that just hole, trap, gas induction tunnel, the horizontal connecting tube of U type, spiral type runner, delay flushing valve, water closet pedestal, blow-off pipe and water inlet interface are formed air-water two phase flow vortex injecting type water-saving toilet pan.With an end and the running water pipe Joint of water inlet interface and the other end and be fixed on delay flushing valve water inlet Joint in the water closet backrest, the delay flushing valve outlet is through horizontal connecting tube of U type and gas induction tunnel inlet Joint, and the gas induction tunnel port of export and spiral type runner inlet are affixed, and the inlet of 1～8 flat nozzle is opened the different parts at the spiral type runner, and it is affixed with the flat nozzle entrance, and this nozzle is round the center, hole is a limit to fall just, press the Archimedes spiral layout that ρ=a θ equation is described, tap water forms air-water two phase flow through gas induction tunnel injection air and makes flushing all increases to some extent of fluid volume and pressure during flushing, this fluid washes away bedpan from Archimedes spiral direction (just hole tangent line promptly falls) again, just can play the effect of not only economizing on water but also can rinse well.

Case study on implementation:

Fig. 1～Fig. 3 also is new health sanitary equipment air-water two phase flow vortex injecting type water-saving toilet pan schematic diagram.Give 9 one baths of delay flushing valve signal (can be sensor signal also machinery press signal) delay flushing valve just opens, tap water through the water inlet interface 13, the horizontal connecting tube 7 of U type, gas induction tunnel 6, flow in the spiral type runner 12, the inlet of 1～8 flat mouthful nozzle 3 links with each corresponding position of spiral type runner respectively, air-water two phase flow will be from the tangential direction ejection of Archimedes spiral, in bedpan 8, form around the high speed circulation in the just hole 4 of falling stool is entrainmented the hole 4 that into falls just after, through trap 5, blow-off pipe 11 rows to sewer.Water closet backrest case 1, water closet removable cover 2, flat mouthful of nozzle 3, fall just that hole 4, trap 5, gas induction tunnel 6, the horizontal connecting tube 7 of U type, bedpan 8, delay flushing valve 9, blow-off pipe 11, spiral type runner 12 and water inlet interface 13 all are contained on the water closet pedestal 10.
