Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of prior application Ser. No. 14/765,255 filed on Jul. 31, 2015, now pending, which is a national stage application of the international application No. PCT/CN2013/071292, the entire contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The invention relates to a high-pressure water-saving close-stool, a type of sanitary product, which is a necessary equipment in the bathroom. This invention has changed long time habits of using an amount of water to flush the close-stool, by the revolutionary use of high-pressure air or high pressure water or a small amount to wash and clean the close-stool.

Brief Discussion of the Related Art

The shortage of water resources is well known. Water consumption of a toilet accounts for about 60% of household water consumption. There is a growing need to save water. Conventional water-saving close-stool of the market are not effective. Some need to be flushed several times, and some just rush waste out of the close-stool, but do not reach the main sewer. Other conventional products or devices described in patent applications have faults. The device described in utility model number CN201220199249.6 has a fault that the number of foot-stepping is not enough, so it only may cause low pressure air. The device described in patent number CN01118907.X, includes a the air outlet which is not sufficient and may cause the high-pressure air to return to the close-stool. When defecating in the close-stool, sometimes the sewage stirred up by excrement or part of the urine will be splashed on a user's body. Toilet covers can be closed loosely so that sometimes a horrible smell is emitted from the toilet. Bacteria will float in the close-stool and cockroaches may climb into the interior through the close-stool, when the water seal tank has no water. The waste left hanging on the wall of the close-stool needs a chemical cleaning agent to clean it away, which takes a lot of time, effort and money, and also pollutes the environment. The noise is relatively large and sometimes the close-stool may get blocked. Long term use of such devices can lead to uncomfortable effects to the user. The invention, however, uses high kinetic energy or water to complete the work efficiently.
The working principle and process of the close-stool is that the waste needs work to be done by the kinetic energy X from the toilet to the main sewer. If it takes a maximum of 6 L water for example, which means 6 L water to produce energy x, it can achieve the same results with an equivalent kinetic energy y. The decrease of the water B leads to the decrease of the kinetic energy B, so that the remaining water C needs to supplement the equivalent kinetic energy D. The remaining water C needs high pressure air to increase a corresponding pressure in order to reach the equivalent substitution of the kinetic energy. When used completely without water, all kinetic energy is provided by a high pressure air, and then it can be washed with a small amount of water.
The formula of substitution principle and process of the equivalent kinetic energy is 6 L water=reduced water B+remainder water C.
Also the equivalent kinetic energy Y=kinetic energy x produced by 6 L water=corresponding kinetic energy B for reducing water B+kinetic energy remainder water C.
The kinetic energy B for reducing water B=increasing the kinetic energy D of remainder water C.
The same equivalent kinetic energy Y=kinetic energy X produced by 6 liters of water=kinetic energy of remainder water C+increasing kinetic energy D of remainder water C.
When the remainder water C=0, the equivalent kinetic energy Y=the kinetic energy X produced by 6 L water=the kinetic energy produced by the high pressure air. If you use the high pressure air to clean the toilet, the best matching problem of the volume and pressure should be considered. If the pressure is large enough, the air volume is also enough.
The main body volume of the close-stool is 2 L-5 L. The volume ratio of the main toilet body, high pressure air tank and high pressure air generator is preferably 1:1:1. Currently, the largest volume of human high-pressure pump on the market is below 1 L:0.5 L. The user needs to pump more times, nearly ten times or at least several times for the high pressure air to meet these requirements. This will cost a lot of labor and time. A high pressure pump with large volume and less effort to achieve an ideal goal or saving water and energy in total is needed. The squatting toilet may be greater than the volume, but may need a high pressure tank and human high pressure air generator.
From the above, it is clear that the more you want to save water, the bigger kinetic energy D remainder water C, namely air pressure, is required. Considering the material, technology, cost and other factors to find a balance point is necessary.

SUMMARY OF THE INVENTION

A high-pressure water-saving close-stool for places such as washrooms comprises a high pressure air generator, a high pressure water generator, a high pressure air tank and a close-stool body. All the parts are enclosed and are capable of bearing the pressure and impact force of high pressure air or high pressure water without damage. The high pressure air generator is used for pressurizing the water in the high pressure water generator or inflating the high pressure air tank, and then the kinetic energy generated by the high pressure water or high pressure air is used for clearing the waste. The high-pressure water-saving close-stool saves water and energy, and is sanitary and generates less noise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In order to solve the above problem, a high-pressure water-saving close-stool has been developed composed of a high pressure air generator, high pressure water generator, high pressure air tank, and toilet body. All component parts can withstand the force and rush produced by high pressure air or the high pressure water pressure for a long time without damage.
There are three types of sewage discharge form of the general close-stool, which include drop type, siphon type and jet siphon type. The invention has advantages over these types because the water consumption is small and it is not easy to be blocked.
Referring to FIG. 1, FIG. 1 is a cross section view of the side of the close-stool according to an example embodiment of the present application. The close-stool includes an upper edge portion 1 having an air and water inlet. The close-stool includes a main toilet body 31 and a protrusion body 32. The protrusion body 32 is protruded from a front opening portion of the main toilet body 31. As shown in FIG. 3, which is a top view of the close-stool, the upper edge of the main toilet body 31 has an outer rim 20 and an inner rim 21. Reference number 22 refers to a user's anus position, which cannot be seen in real product. The area between the outer rim 20 and the inner rim 21 carries a user's buttocks. The outer rim 20 and the inner rim 21 are round shape or approximately round shape and are concentric with reference number 22. As shown in FIG. 3, an opening portion is formed on the front portion of the main toilet body 31. A protrusion body 32 is extended from the front opening portion of the main toilet body 31. The protrusion body 32 has two walls 25, 26 substantially perpendicular to the ground. The distance between two walls 25 and 26 is smaller than the diameter of the inner rim 21. FIG. 1 shows a cross sectional side view of the protrusion body 32. As shown in FIG. 1, the protrusion body 32 has a first slant surface 9 b arranged on the bottom of the protrusion body 32 between the two walls 25 and 26. The first slant surface 9 b has a first end connected to a slant surface 9 a of the main toilet body 31 through the front opening portion. The first slant surface 9 b and the slant surface 9 a form a slant surface 9. The first slant surface 9 b has a second end connected to an end of a second slant surface 11, which is formed on the front portion of the protrusion body 32. The second slant surface 11 has another end connected to two front ends of the two walls 25 and 36. Thus, the first slant surface 9 b, second slant surface 11 and the two walls 25,26 form a urination area in the protrusion body 32. After the urine is reflected by the second slant surface 11, its direction is downward, so that it does not easily splash a user's body. The connection portion between the first slant surface 9 b and the second slant surface 11 may be of an arc shape or may have a sharp angle. An air and water inlet 10 is installed on the connection portion between the first slant surface 9 b and the second slant surface 11.
As shown in FIG. 1, the lines 2 a and 2 b are vertical lines. The region 1 between 2 a and 2 b is the fecal excretion area. The lines 2 a and 2 b are virtual lines and do not exist in real products. Reference numeral 9 a between vertical lines 2 a and 2 b is the drop zone of stool, which is a slant surface. Reference number 3 refers to the toilet side wall. Reference number 4 is the angle a, which is the angle between the vertical line 2 a and side wall 3. It is not a single angle nor a dead angle with a fixed degree. This can play a relevant role since the stool is not easily sprayed onto the side wall due to this angle, and not easily adhere to the wall since it falls into the water seal 6. Reference number 5 is the sewer outside the toilet main body. Reference number 6 is the water seal, which may be of a rectangular shape. Reference number 7 is the width of the water surface or internal surface of the toilet. Reference number 8 is the angle b, which is the angle between the vertical line 2 a and slant surface 9. Reference number 10 is another water and air inlet which is formed on the connection portion between the first slant surface 9 b and the second slant surface 11 of the protrusion body 32.
FIG. 2 illustrates a one-type high pressure water generator. If the high pressure air generator 19 is removed, it becomes a split type high pressure water generator. As shown in FIG. 2, reference number 12 refers to the part for controlling water including the valve. Reference number 13 refers to an air pressure gauge or pressure reducing valve. Reference number 14 refers to a full water surface level. Reference number 15 refers to an outlet. Reference number 16 is the float. Reference number 17 refers to a one-way water inlet and valve. Reference number 18 refers to an one-way air inlet and valve. Reference number 19 refers to a high pressure air generator. Below the water surface 14 is the water storage chamber and above is the air storage chamber.
When the close-stool is in use, excrement falls down on the slant surface 9 a of the main toilet body 31 and then slips into the water seal 6. Urination falls down to the second slant surface 11, and then the slant surface 9 and then slides into the water seal 6. After using and enclosing a toilet cover (not shown in figures), the inlet valve 17 is opened to fill water into the water storage chamber. When the water storage chamber is full, the float 16 closes inlet 17 . Then, a high-pressure air generator 19 is used to bring air to the one-way inletl8. For a quick cleaning method, a large water valve on the water part 12 is opened. High pressure water flows through the water outlet 15 and flushes the toilet wall 3, slant 11 and 9, through the air and water inlet on the upper edge portion 1 of the close-stool and the air and water inlet 10, to work on the urine and a water seal together through water seal 6 and the sewers 5 to the main sewer.
The method for saving more water: Using an external high-pressure air generator to inflate the high-pressure tank inflatable big enough and then open the outlet valve of high-pressure air through a high pressure air tank outlet. The air blows the toilet wall 3, slant 11 and 9, through the and air and water inlet on the upper edge portion 1 of the close-stool and the air and water inlet 10, to work on the urine and a water seal water together through 6 water seal and the sewers 5 to the main sewer. Finally, the small valve of the water part 12 is opened to flush the toilet. The most energy-efficient environmentally method: after cleaning up with high pressure air to open the toilet cover and manually directly use water to flush the toilet wall 3, slant 11 and 9.
One of the patentable features of the present invention is that the kinetic energy generated by high pressure air makes it work. This is, the invention uses the high pressure air generator to add pressure to the water in the water generator or to inflate the high-pressure tank, then uses kinetic energy produced by the high-pressure water or high pressure air to remove waste. The concept in the invention can be explained by the following points.
High pressure refers to a pressure greater than atmospheric pressure. In particular, when the pressure of an air chamber is needed, the pressure of a high pressure water generator, a high pressure air tank and the toilet main body is greater than the outside atmospheric pressure.
High pressure water is ordinary water inflated by a high pressure air so that the water has a certain kinetic energy.
A high-pressure air generator is the equipment needed to produce a high pressure air. These generators can be classified as human type including a manual or pedal high pressure cylinder, or non human type such as an electric high-pressure pump.
A high pressure water generator is the equipment needed to produce high pressure water. These generators can be classified a separately disposed combination of the high pressure water tank and an external high-pressure air generator, or an integral combination made of a high pressure air generator and high pressure water tank combined as one, such as the bucket type manpower car washing equipment.
The angle b shown in FIG. 1 as is the angle between vertical 2 b and incline 9. The smaller the angle, the easier it is for stool to slide.
During cleaning, the toilet cover must be closed and withstand high pressure without damage. It is not limited in the tight way. Idle time, and effective isolation prevents anti odor and flushing the toilet can reduce noise and pollution.
The general toilet body is the toilet bowl in addition to the shape of the internal request with general toilet body.
The opening of the toilet bowl is larger than that of the seat, so that the seat is changed to squat, the other is the same as the main body of the toilet seat.
Generally, the toilet bowl is the general squat toilet bowl, with other aspects of the toilet being the same as the main body of the toilet. The present invention comprises a sitting toilet and a squat toilet so that the same can be used as a sitting toilet and a squat toilet.
Concerning the high pressure air generator, for the non manpower type, if the electric power needed increases the cost, despite the water-saving, the electric does not meet the overall requirements for saving energy and environmental protection.
For the human type, foot type and manual type high-pressure inflators are limited to within 10 is the best and within 5 times is suitable and more times will lead to time-consumption, unnecessary labor and fatigue. Using a high pressure air tank, if you want to get correspondingly sufficient pressure, the volume of high-pressure inflator must be relatively large, but if it requires too much effort, it is not easy to use. Considering the combined effort and a number of other factors, the volume control in the 2-4 L range is more appropriate and not too much trouble.
A high pressure air generator can be combined with a high pressure water generator or a high pressure tank or may be separated.
The high pressure air generator produces a high pressure air which can be used for more than one thing. It can remove the dust from a computer and other electrical devices, and can inflate tires, etc.
The high pressure water generator can be a separate combination or an integral type as described above.
A high pressure water tank can be a split pressure water generator except for the high pressure air generator. Overall it is closed but it can be opened to carry out installation and maintenance work. The upper part is the air storage; the next part is the storage room. It has a one-way water inlet, air inlet and valve, also a one-way water outlet. A one-way water inlet valve can be connected to the tap water, water or second used water. There is not also a water part provided with a water inlet, a water float and a drainage button with two stalls.
A fixed integral type high pressure water generator on the basis of high pressure water tank of the split type high pressure water generator but also increases the high pressure air generator. A high pressure air has two sources for the function of backup. In view of factors of the high-pressure pump on the market stage, the backup is very meaningful. You can also set up an pressure gauge or pressure relief valve.
The high pressure tank may include a one-way air inlet, an outlet and a control valve of inlet and outlet. It can also include an air pressure gauge or pressure relief valve. It can use material technology such as that used in automotive tire valves. After being inflated, the high pressure air tank, in addition to being used this way of the high pressure air generator, can also be combined with the corresponding pipe system into “water cannons” for cleaning and removing dust.
The water inlet and inlet is setup on upper and lower two layers. The upper layer is to keep the entire toilet inside the surface clean. The lower layer is set at the top of the incline a so as to clean it.
The stool falls on the slope and then falls into the water, if the water is not just below the anus. For the overall need for the pressure and the use of high pressure air generator, a volume of 2-4 L is more appropriate for the main body of toilet. Sometimes, high-pressure air or high pressure water shock on the stool inevitably causes a small amount of stool to fly back to the wall of the toilet, so the toilet main body needs a certain height to avoid the stool from flying back to the toilet lid. As long as the size can be guaranteed for smooth drainage into the toilet, when defecating, the surface is too much exposure. In addition to smell there is no other significance. Considering the width of the anus and to avoid drainage to the toilet wall, a width or over 4 cm or nearly 9 cm is appropriate. Considering the distance from the anus to the mouth of the urine and to avoid excretion to the toilet wall the length of over 10 cm or nearly 25 cm is appropriate.
The toilet main body production can be like a pressure cooker by using nonstick material, technology, process and productions acid and alkali corrosion resistance, can bear high pressure, waste does not easily stick and long service life.
Concerning the seal, because all parts of the invention are enclosed, the toilet lid is generally enclosed and is opened only when used.
The volume of water seal should be less than 1 L and 0.5 L may be sufficient. The interior of the toilet water sealing surface width 7 is within 5 cm. In order to ensure that the stool is removed, high pressure of the largest extent acts on the excrement .
The water left standing in the toilet bowl is the puddle. The reasons why the toilet becomes blocked is sometimes the stool with a certain length such as 20 cm, falls into puddles having a longest side such as 10 cm, so that the stool breaks off or is broken, and in this way it is possible, for the sewer line to be blocked up. In order to avoid the occurrence of this situation, the pool in the main body of the invention toilet requires a width less than 5 cm. In other words the width of the sealing surface 7 is a cuboid with a width less than 5 cm and a length above 10 cm. The vertex angle can be a circular arc. The length of the seal is 10 cm and water pipes in the back can also be considered to be this length shape.
After the toilet cover is enclosed, the water storing chamber of the high pressure water generator is filled with water, using a high pressure air generator to inflate the high pressure water generator and high pressure air tank to be large enough. Method 1, the biggest water-saving method: With high-pressure air acting the waste out of the toilet and then stall a small valve to discharge water to clean the toilet and to be used as seal. Water consumption is the least in the method. Method 2, the rapid method with using more water: The direct use of a large file valve to clean the toilet uses more water, but saves time and effort. Method 3, without the use of clean tap water: Reclaimed water or secondary water is placed directly into the toilet and then the high-pressure aires act to finish the tasks or directly by high pressure air acting to complete the task, and finally a small amount of reclaimed water or secondary water to wash toilet wall and to be used as the water seal. This has the most environmental protection.
The beneficial effects of the invention are described below.:
First, the invention saves saving water and money. The excrement uses water within 3 L and the urine uses the water within 1 L. Furthermore, the excrement and urine will not splash to the body; because the three round bottom pots of special design guarantees in addition to the stool falling slope of other places almost no contact with stool. The toilet is generally enclosed except when it is used even if there is no water in the water seal, so the toilet has no unpleasant smells. Furthermore, bacteria do not have floating pollution and cockroaches can not come into the room through the toilet .
Moreover, the invention saves time and effort and provides environmental protection. The special shape of the main body of the design and the use of non stick coating ensures that the toilet also does not need to use a chemical cleaning agent.
Furthermore, the invention has a long service life, by using a design of high pressure cookers such as putting a few layers of non-stick coating.
The invention also reduces noise. The whole toilet is enclosed using a small amount of high pressure air or high pressure water to naturally decrease the noise power.
The high pressure air generator can be used for more than one thing.
There is no jamming. Powerful kinetic energy is generated by a high pressure air and the shape and size of the puddle prevents jams.
The device is comfortable due to a humanized design of the three round bottom pot with human body engineering and human mechanical structure.
The best implementation of the invention is the most energy saving and environmental protection. The invention provides a maximum degree of water saving and increase of other energy consumption. Considering now the marketed human type high-pressure inflator and its problems, a human type high pressure air generator and one type high pressure water generator common configuration is better. The full version of the invention includes a human type high pressure air generator, one type of high pressure water generator, high pressure tank and the toilet main body.
After the toilet seat lid is enclosed cleaning of excrement can be completed in the following methods.:
The first method is the biggest water-saving method. After using the manpower high pressure air generator for high pressure air tank to inflate enough air, the outlet valve is opened using the high pressure air cleaning stool. One type of high pressure water generator feed water tank is water pressurized to be large enough, then opening the small valve switch drain flushing the toilet main body.
The second method is a rapid method using more water.: An integral pressure water generator or high pressure air generator causes pressure in the water in the high pressure water tank, open valve switch drain flushing the toilet main body. When there are fewer stools opening a small valve switch to flush the toilet body. Urine: with one type of high pressure water generator or high pressure air generator causes pressure to the high pressure water tank large enough to open the small valve switch to flush the toilet body.
The method of fasting and saving energy and water is to use the no manpower high pressure air generator to produce the high pressure air to complete the task, and then use a little water to flush the toilet wall. But the increase of the power consumption, increase the cost of electric pumps and maintenance costs etc. On the whole, it is not energy-saving and environmentally friendly. Because of the use of methods and principles are similar, so the following is the key column different from the combination of the human resources of the high-pressure air generator. If it is based on the invention as the core and the other functions are added and no substantial differences are also in the scope of protection of the invention. The following is part of the implementation of the invention, not to limit the scope of the invention.
The toilet may include a full version including a high pressure air generator, one type high pressure water generator, high pressure air tank and general toilet body.
Alternatively, the toilet may include a simplified version of the full version without a high pressure tank, (the other components are unchanged). Accordingly, the cost can be reduced, with more water.
Another simplified version of the full version of can be provided without a high pressure tank (the other components are unchanged)., the others are unchanged, Accordingly, the cost can be reduced, with more water.
Another full version of the toilet can include a sub type high pressure water generator that is high pressure water tank, high pressure air generator, high pressure tank and the toilet main body.
Another full version of the toilet can include a split type high pressure water generator that is high pressure water tank, high pressure air generator, high pressure air tank and the toilet body.
Another simplified version of the invention is envisioned which includes a complete version without the high pressure tank and a high-pressure air generator, composing one high pressure water generator and the toilet main body.
Another simplified version can be provided without a high pressure tank and a high-pressure air generator, composing one type high pressure water generator and the main body of the toilet.
Another simplified version can be provided without a high pressure tank, composing split type high pressure water generator that is high pressure water tank, high pressure air generator, and a toilet body.
Another simplified version can be provided without high pressure tank, composing split type high pressure water generator that is high pressure water tank, high pressure air generator, and general toilet subj ect.
Finally a squat version of the toilet is provided. In the squat toilet, there is no essential difference between the base and the seat, in accordance with the above examples for simple replacement. In fact, as long as the opening of the above toilet body is changed large and changed into squat, the other is unchanged, as can be water-saving.
