Description
Technical field
The present invention is about a kind of water storage Washdown type toilet seat, espespecially a kind of toilet seat that comprises water storage Washdown type flushometer.
Background technology
Along with the development in epoch, the progress of science and technology, there has been new requirement in country to the sustainable development of environment. Ceramic sanitary ware industry is no exception, and its research and development, production more show the important of energy-saving and emission-reduction work. Agenda has been mentioned in sanitary ceramics energy-saving and emission-reduction work. Country's construction sanitary ceramic industry " 12 " development plan clearly proposes: advance sanitary ceramics lightweight, slimming work, development lightweight, slimming, water-saving, functionalization product, advocate small volume product, realizes sustainable development. But just current, the toilet seat on market also has the following disadvantages in this respect:
The first, well-known, since over half a century, in ceramic family, conjoined toilet product has formed industry size at home and abroad, and occupies an important position in economic and social life. But traditional conjoined toilet is all with ceramic water tank, and ceramic water tank volume is larger, then cause product material and weight to increase; In addition, because ceramic water tank volume is larger, making the actual stool flushing amount of product on existing market is 6-7 liter, and urine flushing amount is 4.8-5 liter. Based on this, the brand product that on market, product can be up to state standards is completely very few, can not meet the requirement of energy-conserving and environment-protective.
In addition, the ceramic water tank that traditional toilet seat adopts, be subject to the restriction of ceramic process, the size of ceramic water tank is inaccurate, tolerance is larger, and situation that can not fine control based on precision additionally need to be used large sealing ring to solve the problem of error in assembling process, the cost of increase equipment, to having relatively high expectations of ceramic body.
Particularly, in traditional toilet seat, due to ceramic water tank being set, must need supporting water inflow and the drainage element of arranging, they are all plastics auxiliary equipments, are all a pattern over more than 50 year, have consumed a large amount of raw materials and manpower and material resources.
The second, current, there is part producer to start the toilet seat of development without ceramic water tank, it only simply adopts the open and close of solenoid control bath mostly. But due to its different environments for use of different consumers, these, in the time of water source dynamic water-pressure < 0.11MPa, there will be and cannot wash by water or shortcoming that flushing effect is bad when the low hydraulic pressure low discharge without ceramic water tank toilet seat.
Trace it to its cause and be, siphonage can be caused by liquid intermolecular attraction and potential difference, utilizes water column pressure poor, makes liter waterborne flow to lower again. Because the mouth of pipe water surface bears different atmospheric pressures, water can by pressure large flow to pressure little while, until the pressure on both sides equate, the water surface in container becomes double altitudes, water will stop flowing. Flow scrubbed by traditional product and toilet and pressure is little, does not become certain pressure poor, causes not becoming siphon, and therefore flushing effect is bad, can not reach national water saving conjoined toilet product standard. Thus, seriously affected without the development of ceramic water tank toilet seat with universal.
Based on this, for toilet seat product, how can be in water saving, the normal bath while realizing ultralow hydraulic pressure low discharge, is current problem demanding prompt solution.
Summary of the invention
The defect existing for above-mentioned prior art, technical problem solved by the invention is providing a kind of water storage Washdown type toilet seat, in low hydraulic pressure low discharge situation, this toilet seat can utilize supercharging device normally to complete bath, even in the time that supercharging device damages, this toilet seat self still can at least complete once bath.
For solving the problems of the technologies described above, the invention provides a kind of water storage Washdown type toilet seat, it comprises water storage Washdown type flushometer, this water storage Washdown type flushometer comprises water feed apparatus, water tank, shirt rim flushometer and bottom water replanishing device, wherein, on water tank, be provided with brushless centrifugal water pump, this is brushless, and centrifugal water pump is connected with shirt rim flushometer and bottom water replanishing device by jockey.
Owing to setting up brushless centrifugal water pump on water tank, the in the situation that of low hydraulic pressure low discharge, this centrifugal water pump is opened automatically, and the speed that can accelerate current increases hydraulic pressure then, and toilet seat flushing system can normally be worked, and has widened the range of application of toilet seat.
In addition, in traditional Washdown type toilet seat, mainly the difference in height based on current finally realizes the process of bath. In other words,, for guaranteeing that dirt is all rinsed, must use large water tank to guarantee to produce enough water flow velocities, water pressure. Thus, the comparatively water wasting of traditional toilet seat, and because the volume of water tank is larger, be not suitable for being arranged in relatively little space, seriously limit the range of application of this toilet seat. And in the present invention owing to creatively setting up brushless centrifugal water pump, make only to rely on current difference in height and the current volume quality that ensures to wash by water, can effectively reduce thus toilet seat water tank volume, reduce water consumption. Be consistent with the trend of present energy-conserving and environment-protective.
In the present invention, water tank, in realizing water storage function, can doublely play cushioning effect. Specifically, because the setting position of water tank is higher than shirt rim flushometer and bottom water replanishing device, in the time that brushless centrifugal water pump can not be worked, can utilize difference in height, still can realize bath at least one times.
And, in the present invention, water tank adopts plastic material and upper and lower splicing construction, compared to the ceramic water tank of prior art, the precision of the size of the plastic cistern of plastics amalgamation structure is significantly improved, and more easily realizes Miniaturization Design and standardized production and standardization and install.
One as present device is improved, and can make to be provided with flowmeter on this water feed apparatus. Use traffic meter detects the discharge of water feed apparatus, and controls the unlatching of brushless centrifugal water pump or close with this, makes whole process more intelligent, accurate. The particularly important is, the flowmeter that has used conventional water heaters to use, high reliability, calculates discharge accurately. When little water tank is low as buffered water flow (flow per minute is less than 13L), the supercharging of starting brushless centrifugal pump, when discharge is high, air pump inoperative, utilizes the pressure of running water directly to wash by water, and pump supercharging and the combination flinging reduce the requirement to hydraulic pressure. If pressure charging system breaks down, (booster pump or flow are in respect of fault, and relatively this probability the is very little) system that flings is at dynamic water-pressure > 0.11MPa, can also the whole water-rinsing process of complete independently, reduce maintenance rate.
In addition,, in existing toilet seat, in water feed apparatus, water tank, shirt rim flushometer and bottom water replanishing device, a large amount of electronic devices can be set, when in the excessive situation of flow of inlet water, very easily cause the loss of electronic device, reduced the service life of toilet seat, caused a large amount of economic losses. For this reason, as another improvement of the present invention, in the present invention, water feed apparatus includes filter and entering water electromagnetic valve, between this filter and this entering water electromagnetic valve, pressure-reducing valve is set. Entering water electromagnetic valve, as first electronic equipment of current warp in flushometer, arranges pressure-reducing valve before it, can effectively reduce water flow pressure. This pressure-reducing valve is opened in the time that discharge is excessive, closes the electronic device in the flushometer of protection to a great extent, the service life of having improved equipment in discharge during lower than safety value.
But due to brushless centrifugal water pump being set in flushometer of the present invention on water tank, in the time that centrifugal water pump is opened, the operation principle based on centrifugal water pump makes to be easier to occur the situation that hydraulic pressure is excessive or air pressure is excessive in water tank. If hydraulic pressure is excessive in water tank, water tank sidewall is very easily caused to loss, particularly, in the time that water tank adopts plastic seal water tank, hydraulic pressure is more remarkable for the infringement of water tank. And if water tank internal gas pressure exceedes water feed apparatus water inlet hydraulic pressure, water cannot enter into water feed apparatus.
Based on this, for solving the excessive problem of hydraulic pressure in water tank, the invention provides another improvement, decompression protection device is set on water tank. In the time that hydraulic pressure in water tank arrives warning line, this pressure relief device is opened, and discharge section water, reduces hydraulic pressure in water tank with this.
Specifically, as a kind of detailed description of the invention of pressure relief device in the present invention, this pressure relief device comprises pressure release sealing gasket, pressure release jacking block, pressure release spring and pressure release shell, and this pressure release jacking block is connected with this pressure release spring. In the time that in water tank, hydraulic pressure is excessive, can push pressure release spring and make it that elastic deformation occur, then drive the pressure release jacking block being attached thereto to move, in water tank, part water flows out from this. When hydraulic pressure in water tank is during lower than warning line, in water tank, water reduces gradually to the extruding force of pressure release spring, and pressure release spring returns to reset condition gradually, and pressure release jacking block turns back to home position then, and in water tank, water no longer flows out. So repeatedly, guarantee that in water tank, hydraulic pressure still can maintain comparatively safe level in the time of brushless centrifugal water pump work.
In addition, for solving the excessive problem of water tank internal gas pressure, the invention provides another and improve, exhaust apparatus is set on water tank. In the time that water tank internal gas pressure is more than or equal to water feed apparatus water inlet hydraulic pressure, this exhaust apparatus is opened, side by side portion gas in water tank; After this,, in the time that water tank internal gas pressure is less than water feed apparatus water inlet hydraulic pressure, this exhaust apparatus cuts out automatically. Repeat said process, guarantee and maintain water tank internal gas pressure all the time lower than water feed apparatus water inlet hydraulic pressure, then ensure that water can continue to enter water feed apparatus.
Specifically, as a kind of detailed description of the invention of exhaust apparatus in the present invention, this exhaust apparatus comprises exhaust water float, the floating sealing gasket of exhaust water and exhaust shell. In the time that water tank internal gas pressure is more than or equal to water feed apparatus water inlet, when hydraulic pressure, this exhaust water float is opened automatically, and the portion gas in water tank is discharged from exhaust water float; In the time that water tank internal gas pressure is less than water feed apparatus water inlet hydraulic pressure, this exhaust water float cuts out automatically.
Consider the volume that reduces to a greater extent water tank in toilet seat, in the present invention, pressure relief device and exhaust apparatus can adopt integrated design, reduce the surface area of water tank with this. For instance, this pressure relief device and the exhaust apparatus setting that can superpose. Now, can save the exhaust shell in pressure release shell and the exhaust apparatus in pressure relief device, replace an exhaust pressure relief shell is only set. Such integrated design, effectively reduces pressure relief device and the exhaust apparatus area occupied on water tank, is then more conducive to the miniaturization of water tank. Certainly, be not limited to above-mentioned set-up mode for the integrated design of pressure relief device and exhaust apparatus herein, as long as finally can reduce pressure relief device and the exhaust apparatus area occupied on water tank.
It is worth mentioning that; in the present invention, water feed apparatus, water tank, shirt rim flushometer, bottom water replanishing device, decompression protection device and exhaust apparatus are the integrated design; taking water tank as assembling main body, many places adopt hard connecting mode simple, convenient production and maintenance. Many places key points adopts multiple protective, reduces whole device and go out the possibility of risk. And water tank of the present invention can adopt plastic seal water tank to substitute traditional ceramic water tank, under comparing, plastic material parts have better performance on saving space.

Below the workflow of a kind of water storage Washdown type of the present invention toilet seat is described in detail, and please refer to Fig. 2, Fig. 3.
First, the course of work of present device is described in normal discharge water pressure situation.
At running water dynamic water-pressure >=0.03MPa, when flow velocity >=6L/min, need to can not complete bath by brushless centrifugal water pump 26 in principle, and reach ideal effect. Now, running water enters water feed apparatus from entering check valve 5, enters pressure-reducing valve 7 and carry out pressure adjusting after filter 6 filters. Press the flush button of toilet seat, procedure auto-control entering water electromagnetic valve 8 and shirt rim bath magnetic valve 19 are opened, and now running water enters in water tank by flowmeter 9. When flowmeter 9 records tap water Flow Velocity, in the time that flow velocity is more than or equal to 6L/min, by extremely brushless centrifugal water pump 26 places of signal feedback, and the brushless centrifugal water pump 26 of instruction cuts out.
Will automatically close entering water electromagnetic valve 8 when 12 marker locations of water yield arrival float ball for use in cistern switch stops into water. Meanwhile, enter running water in water tank and enter magnetic valve threeway 20 through brushless centrifugal water pump 26 and then enter shirt rim bath magnetic valve 19, running water is through shirt rim bath flexible pipe 22, and carries out the moisturizing of washing away to toilet seat from 3 ejections of shirt rim flush port.
After this, program is automatically closed shirt rim bath magnetic valve 19 and is opened bottom moisturizing magnetic valve 21, and running water enters bottom moisturizing magnetic valve 21, then enters refill hose 23, and now running water will spray from bottom water supplement port 4, and forms syphon flushing water. After water-filling completes, program is automatically closed bottom moisturizing magnetic valve 21 and again opens shirt rim bath magnetic valve 19 and carry out moisturizing, so far completes the water-rinsing process of a circulation.
Said process carries out repeatedly, realizes the bath under normal water flow water pressure. Certainly, arrange by reprogramming, can in the time of normal water flow water pressure, open brushless centrifugal water pump 26 equally, further promote flushing effect.
Secondly, the course of work of present device is described in ultralow discharge water pressure situation.
In the time that discharge is less than 0.13L/min or dynamic water-pressure and is less than 0.11MPa, need to could realize normal bath by the booster action of brushless centrifugal water pump 26. The part repeating with the course of work of equipment under normal water flow water pressure does not repeat them here, different is, in the time that flowmeter 9 detects that discharge is less than 0.13L/min, by extremely brushless centrifugal water pump 26 places of signal feedback, and the brushless centrifugal water pump 26 of instruction opens, then realize the water-rinsing process of circulation.
In addition,, in the time that in water tank, hydraulic pressure is greater than 0.16MPa ~ 0.2MPa, decompression protection device starts. Be that in water tank, running water makes pressure release spring 17 that elastic deformation occur, then drive pressure release jacking block 16 to move, in water tank, part of running water flows out from pressure release jacking block 16, and is discharged by closet body 1. In the time that water tank internal gas pressure is more than or equal to water feed apparatus water inlet water pressure, exhaust apparatus is opened, and in water tank, portion gas is discharged from exhaust water float 13, and is discharged to outside closet body 1. Herein, water feed apparatus water inlet water pressure can be calculated and be learnt by flowmeter 9 place's reading out datas, and can obtain with excessively barometric surveying being set in water tank by water tank internal gas pressure. Measuring method can be chosen, adjust according to different environment, does not limit at this.
Finally, under extreme case, as in the time that ultralow pressure low discharge and brushless centrifugal water pump 26 cannot normally be worked, setting of the present invention still can complete bath at least one times. Specifically, due to water tank being set, and have difference in height between water tank and shirt rim flush port 3 and bottom water supplement port 4, itself can form syphon flushing water. And brushless centrifugal water pump 26, compared to membrane pump etc., itself had both had the function of buffering.
It should be noted that: in the present embodiment, water tank adopts plastic cistern, does not adopt ceramic water tank, and one of reason is based on technical reason, the size of ceramic water tank is inaccurate, the poor general meeting of work is in ± 3mm left and right, and to the having relatively high expectations of ceramic body, common ceramic body is difficult to be compressed to the size of little water tank. But, while selecting plastic cistern, to pay special attention to, select relatively abundant plastic material as far as possible. And in traditional toilet seat, mostly adopt vacuum valve or membrane pump to carry out supercharging, and because the On/Off of valve itself just needs certain pressure, in the situation that pressure is less than 0.3Mpa, vacuum valve cannot be realized unlatching/relation. Therefore in ultralow discharge water pressure situation, vacuum valve can not play the effect of supercharging.
Through actual measurement, above-described embodiment equipment, under normal circumstances, the life-span of brushless centrifugal water pump is greater than 30,000 hours; In the time that the inner pressurized of water tank is less than 0.13MPa, impact of water hammer approximately 100,000 times. Thus, greatly improve the service life of toilet seat, more economically, environmental protection.
