Technical Field

Background

The current urban commodity house households in China are nearly 3 hundred million, and rural households are 2.5 hundred million. Because the squatting pan has the advantages of occupying no three-dimensional use space of the bathroom, being convenient for use, having low cost, being convenient for draining and dumping fine slag and being not easy to be blocked, at least one squatting pan is arranged for households living in the south of China. Therefore, the existing squatting pan in China has the holding quantity of at least more than 3 hundred million. Then, the research of improving the use value of the squatting pan is an important subject.

Because of the self structure of the squatting pan, the squatting pan without a trap and the squatting pan with a trap available in the market at present are both in a straight-falling type replacement mode, and have the following serious problems in common:

1, the installation condition is harsh. In modern buildings, the depth standard of the sink of the bathroom is 380-400 mm. When the building is designed, a 110 mm thick sewage main pipe is separated from the bottom plate of the sinking tank by 60-80 mm. Then the total height of the squatting pan body must not exceed 230 mm. All interfaces of the squatting pan are generated on the central axis of the basin bottom, and the basin bottom can only be made shallow due to the limitation of a water seal clamping point and a sewage pipe diameter, and the depth of the middle part of the basin bottom is generally only 60-80 mm. And will not be installed as long as this depth is exceeded.

2, The water storage surface of the basin bottom is small. The squatting pan without the trap is characterized in that the trap is generated on an externally connected U-shaped elbow, and the bottom of the squatting pan is completely immersed in water. The squatting pan with the trap has good quality, and the product has a water storage area of 80X120 mm, and most of the basin bottom area has no water storage, so that the kinetic energy of water is not concentrated when the water is flushed due to the fact that the water storage area is large, and the replacement effect is seriously affected. The biggest problem of small water storage area is that the excrement is easy to be stuck to the bottom of the basin, the management is very troublesome, and furthermore, the excrement is exposed to the air when the toilet is used for a long time and is very smelly.

And 3, the flushing noise is very large. The straight-falling flushing principle is that under the condition that the water storage depth of a water storage area is unchanged, dirty water and dirt are forced to be pushed away from the water storage surface by high pressure and large water flow to be replaced, and the impact sound of the water flow is unavoidable and is generally more than 72 dB. When people use the toilet at night, people in all rooms are disturbed.

4, The water consumption is very high. The water stored in the drain pipe at the bottom of the basin is approximately 2 liters, the water flow with high pressure and high flow rate is smashed from top to bottom, the original dirty water is thoroughly replaced, and the water is not used at all. Therefore, the water consumption of the existing squatting pan is generally 6 liters.

5, The floating objects are difficult to replace. In order to replace the floating objects, two conditions are required, namely, the whole area of the water storage surface needs to be smashed downwards by water flow, and the original water storage volume needs to be completely replaced. The water storage surface of the squatting pan with the water storage bend is 80X120 mm, and water is not supplied to one side close to the bottom of the pan. So, sometimes a cigarette end is rinsed even several times, and the floats are always washed out of the water.

How to solve the above problems of the existing squatting pan.

Disclosure of utility model

The utility model relates to sanitary ware, in particular to a siphon squatting pan with a siphon blow-off pipe, which is characterized in that a water flow with higher pressure at a water inlet is guided to an injection hole below the water storage surface of a blow-off inlet by an auxiliary flushing pipe, the water flow at the bottom of a washing Kong Xishua basin is fused with the water flow with higher kinetic energy at the injection hole and then is quickly discharged out of a basin bottom outlet, a water blocking bend is arranged at the lower part of a main body of the siphon blow-off pipe, when the quick water at the outlet of the basin bottom passes through, a negative pressure area is quickly formed into higher negative pressure, an eccentric interface is designed at a reserved main pipe of the connection building, and a larger water level difference is realized between the water flow discharged from the tail end of the eccentric interface and the water flow in the negative pressure area, so that a quick and good negative pressure siphon effect is realized at the blow-off inlet.

Most toilets are known to use siphon displacement, the displacement is quick and complete, and the silencing and water-saving effects are good. The nature of the siphon principle is caused by the difference in attraction and potential between liquid molecules. The existing squatting pan is a straight-falling type replacement mode which can not form siphonage on a sewage drain pipe due to the self structure.

The technical problem is solved by providing the siphon squatting pan with the sleeved siphon drain pipe, which comprises a squatting pan main body, a water inlet, a drain inlet, a water supply ring, a washing hole, a panel, a basin bottom, an auxiliary flushing pipe, an injection hole, a basin bottom outlet, a sealing interface, an eccentric interface, a water blocking bend, a water sealing clamping point, a negative pressure area, a water soaking section and the siphon drain pipe main body, and is characterized in that the auxiliary flushing pipe guides water flow with higher pressure of the water inlet to the injection hole below the water storage surface of the drain inlet, and the water flow for washing Kong Xishua basin bottom is fused with water flow with higher kinetic energy of the injection hole and then is rapidly discharged out of the basin bottom outlet; the siphon sewage draining pipe has one main siphon body with water blocking bend in the lower part to form great negative pressure in the negative pressure area, and one eccentric port in the main sewage draining pipe to realize great water level difference between the water flow in the eccentric port and the water flow in the negative pressure area, so as to realize fast and excellent negative pressure siphon effect in the sewage draining inlet.

Optionally, the basin also comprises a sealing ring arranged at the sealing interface, and the joint position of the basin bottom outlet and the sealing interface is not limited in height and direction.

Optionally, the size of the aperture and the injection direction of the injection hole are not limited.

Optionally, the pipe diameter of the siphon sewage drain pipe main body is arbitrarily selected from 41-58 mm.

Optionally, the position of the water resistance bend designed on the siphon drain pipe main body can be arbitrarily selected according to the test effect.

Optionally, the siphon drain pipe main body can be formed by a smooth integral pipe or a pipeline with multiple sections in sealed connection.

The eccentric interface is arranged as a big circle, an eccentric sleeve and a small circle, and can be designed on the siphon drain pipe main body or can be in field sealing and splicing with a reserved pipeline of a building, wherein the outer diameter of the reserved pipeline is usually 110 mm.

Optionally, the source of the kinetic energy of the water flow of the injection hole is not limited, or the kinetic energy of the water level of the water tank or the kinetic energy of the water pressure of tap water is used.

Alternatively, the injection holes are either single hole injection or multi-hole injection.

Optionally, the structural shape of the siphon drain pipe main body and the water resistance bend can be arbitrarily selected.

Compared with the existing direct-falling type replacement squatting pan product performance in the industry, the siphon squatting pan sleeved with the siphon blow-off pipe has the following advantages:

1, the siphon blow-off pipe is arranged at the outer side of the basin bottom, thereby solving the problem that the siphon blow-off pipe cannot be arranged when the basin bottom is deeper. The reserved depth standard of the sink pool of the toilet in the general building is 380-400 mm, and a 110 mm thick sewage main pipe is 60-80 mm away from the bottom plate of the sink pool, and finally the height of the main pipe for installing the squatting pan body cannot exceed 230 mm. Moreover, all interfaces of the squatting pan are generated on the central axis of the basin bottom, and the basin bottom can only be made shallow due to the limitation of a water seal clamping point and a sewage pipe diameter, and the depth of the middle part of the basin bottom is generally only 60-80 mm. And will not be installed as long as this depth is exceeded. In daily use of people, too shallow a basin bottom is easy to splash, and in addition, feces are worried about colliding with the buttocks during toilet. The siphon squatting pan sleeved with the siphon drain pipe is characterized in that the siphon drain pipe is arranged on the side surface of the basin bottom, and the height of drain cannot be limited by the basin bottom. The squatting pan can be installed as long as the total height of the siphon blow-off pipe is lower than 340 mm, and the squatting pan is not directly related to the depth of the basin bottom.

2, The siphon blow-off pipe is arranged at the outer side of the basin bottom, thereby solving the problem of small water storage surface of the basin bottom. The squatting pan without the trap is characterized in that the trap is formed on an externally connected U-shaped elbow, the bottom of the pan is not only completely free of water, but also provided with a section of black hole at a sewage draining inlet, and excrement is stuck on the squatting pan and cannot be brushed, because the squatting pan is a connecting port, people with difficulty in seeing and returning smell are long familiar. The squatting pan with the trap has a water storage area of 80X120 mm, but most of the basin bottom area has no water after the water storage is too close. There is also a problem in that the kinetic energy of water is not concentrated when the water storage area is large, resulting in a straight-drop type flushing. When people use the toilet, the feces are very troublesome to clean after being stuck to the bottom of the dry basin, and the feces are very smelly when the people use the toilet. The siphon type squatting pan sleeved with the siphon drain pipe is characterized in that the siphon drain pipe is arranged on the side surface of the basin bottom, and the depth of the basin bottom can be designed according to the requirement of the size of the water storage area, so that the problem of shallow basin bottom is solved, and the problems of the size of the water storage area and the water storage depth are solved.

And 3, after the siphon pollution discharge is sleeved, the flushing noise is greatly reduced. The current squatting pan is limited by the structure and can only adopt a straight falling type replacement mode, dirty, water and dirt are forced to be pushed from the water storage surface by high pressure and large water flow to be replaced, and the impact sound of the water flow is unavoidable and is generally more than 72 dB. This noise is unacceptable to a consumer for a piece of household product. When people use the toilet at night, people in all rooms are disturbed. The siphon type squatting pan sleeved with the siphon drain pipe is characterized in that the siphon drain pipe is arranged on the side surface of the basin bottom, the original straight-falling type replacement mode is changed into the siphon type replacement mode, water for washing the basin bottom can be soft, and the water jet with strong kinetic energy helps replacement in the dark under the water storage surface and does not generate any sound. According to multiple detection, the 72 dB noise of the existing squatting pan can be reduced to about 40 dB.

And 4, after the siphon pollution discharge is sleeved, the water consumption can be greatly reduced. The squatting pan in the current market is characterized in that dirty water is completely replaced by high-pressure and high-flow water from top to bottom, and the water is absolutely not used. Therefore, the water consumption of all squatting pans is generally 6 liters. The siphon type squatting pan sleeved with the siphon drain pipe is characterized in that the siphon drain pipe is arranged on the side surface of the basin bottom, the original direct-falling type replacement mode is changed into the siphon type replacement mode, the water tank of the closestool is only 20 centimeters high, the primary water saving can be realized after the jet siphon replacement, the water tank of the squatting pan is 90 centimeters high, the jet pressure is higher, and the water saving can be completely realized compared with the closestool. The fact has proved that the water consumption of the reformed squatting pan can reach the national replacement standard only by about 3 liters after multiple times of detection.

And 5, after the siphon pollution discharge is sleeved, the floating objects are replaced smoothly. The squatting pan popular in the current market is in a straight-falling type replacement mode, the whole area of the water surface is required to be smashed downwards in order to replace floating objects, and the original water surface is required to be completely replaced. The water can not be smashed on the side of the water storage surface close to the bottom of the basin, so that the floaters are very difficult to replace. The siphon squatting pan sleeved with the siphon drain pipe is characterized in that the siphon drain pipe is arranged on the side surface of the basin bottom, the original direct-falling type replacement mode is changed into the siphon type replacement mode, the air in the negative pressure area is immediately squeezed away by strong water flow with the spray hole, the whole drain pipe is helped to realize the fastest and best negative pressure siphon effect by water bending resistance, and the original water and floaters in the basin bottom are completely siphoned away.

Drawings

Embodiments of the present utility model will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an implementation structure of a siphon squatting pan sleeved with a siphon sewage drain pipe.

The water-saving toilet comprises a 1-squatting pan main body, a 2-water inlet, a 3-sewage inlet, a 4-water supply ring, a 5-washing hole, a 6-panel, a 7-basin bottom, an 8-auxiliary flushing pipe, a 9-spraying hole, a 10-sealing ring, a 11-basin bottom outlet, a 12-sealing interface, a 13-eccentric interface, a 14-water-blocking bend, a 15-water-blocking clamping point, a 16-negative pressure area, a 17-soaking section and a 18-siphon sewage pipe main body.

Detailed Description

FIG. 1 shows a specific embodiment of the siphon squatting pan sleeved with the siphon drain pipe. The squatting pan main body 1 is provided with a water inlet 2 which is communicated with a water supply ring 4 and an auxiliary flushing pipe 8. The basin bottom 7 is combined with the panel 6, the water supply ring 4 and the basin bottom outlet 11. The water supply ring 4 is provided with a plurality of washing holes 5. An injection hole 9 is arranged below the water storage surface of the sewage inlet 3 and is communicated with the auxiliary flushing pipe 8. The sealing ring 10 is arranged at the tail end of the basin bottom outlet 11 and is used for ensuring that the basin bottom outlet 11 and the sealing interface 12 are tightly combined together, a water inlet on the siphon drain pipe main body 18 is the sealing interface 12, and a section of water pipe section which is inclined upwards is named as a soaking section 17 after the sealing interface 12. The water seal clamping point 15 is a key for controlling the water storage depth of the basin bottom. The empty pipe area above the water seal clamping point 15 is named as a negative pressure area 16, and a water blocking bend 14 is arranged at a pipeline position below the middle of the water seal clamping point 15 to the eccentric joint 13.

The following aspects are noted or changed in the specific design:

1, the joint position of the basin bottom outlet 11 and the sealing interface 12 is not limited in height and direction, because the squatting pan main body 1 is convenient to produce and the siphon drain pipe main body 18 is convenient to compactly install.

2, The size of the aperture of the spray hole and the spray direction are not limited because the amount of water used for washing and spraying is distributed in consideration of the siphon drain body 18 achieving optimal siphon and minimum water consumption.

The pipe diameter of the siphon drain pipe main body 18 is arbitrarily selected from 41-58 mm, because the pipe diameter of the siphon drain pipe main body 18 needs to meet the national standard industry standard, and meanwhile, the pipe diameter needs to be set by considering the water flow of the water inlet 2. The pipe diameter is too thick, and the requirement of negative pressure formed by the pipeline cannot be met.

4, The position of the water resistance bend designed on the siphon blow-off pipe main body can be arbitrarily selected according to the test effect.

The siphon sewage draining pipe main body 18 can be formed by a smooth integral pipe or a pipe with multiple sections in sealed connection, and the more the integral pipe is divided into sections, the more flexible the installation and the lower the manufacturing cost, and can be an option. However, the number of the joints is large, the sealing is more difficult, and the smoothness of the pipeline is poor.

6, The eccentric interface 13 can be arranged as a big circle and a small circle, so that the maximum water level difference is realized between the water flow discharged from the tail end of the eccentric interface 13 and the water flow in the negative pressure area 16, and the fastest and best negative pressure siphon effect is realized at the sewage inlet 3. The eccentric joint 13 can be designed on the siphon drain pipe main body, and can also be in field sealing splicing with a 110 mm external diameter pipeline reserved in a building, because the eccentric joint is realized in a plurality of ways, but the drain pipe can be in sealing connection with a shaped eccentric joint with great difficulty, so the eccentric joint 13 matched with the 110 mm is recommended to be generated together with the pipeline of the water resistance bend 14. Of course, the use of eccentric couplings of the large and small tubes is not completely excluded.

7, The source of the water flow kinetic energy of the spray hole 9 is not limited, or is the potential energy of the water level of the water tank, or is the kinetic energy of the water pressure of the tap water, because some water is supplied or the tap water pipe is directly connected by the water inlet 2, other high-pressure water sources can be additionally added near the spray hole 9 to help the siphon blow-off pipe main body 18 to realize the powerful siphon displacement effect.

8, The jet hole 9 is either single hole jet or multi-hole jet, and mainly considering design, the kinetic energy of water flow should be distributed to the most appropriate part of the sewage inlet 2 according to flow rate and pressure to achieve the best siphon effect, so the jet hole 9 is one or a plurality of jet holes.

The structural shapes of the siphon drain pipe main body 18 and the water-stop bend 14 can be arbitrarily selected, and the shapes of the siphon drain pipe main body 18 and the water-stop bend 14 can be arbitrarily selected because the siphon effect of the drain pipe is considered to be several, and the optimal problem is only to be solved according to the specific structure of the ceramic, so that the accurate standard is not optimal and is difficult to find.

After the flushing is started, the siphon displacement process of the siphon squatting pan sleeved with the siphon blow-off pipe is as follows, wherein the water inlet 2 is connected with a water tank with the height of about 1 meter, and the water level difference of the stored water in the water tank from the water inlet 2 is about 90 cm. This height difference is 3 times that of a typical toilet with a ceramic tank. Therefore, when people press the flushing button, the water inlet 2 can supply water to the water supply ring 4 and the auxiliary flushing pipe 8 at the same time due to strong water flow. The water supply ring 4 can determine the number of the washing holes 5 according to the pressure to control noise. The pipe diameter of the auxiliary flushing pipe 8 completely meets the flow rate of the spraying hole 9, so that the beam flow with powerful kinetic energy of the spraying hole 9 is fused with the water flow of the basin bottom 7 of the washing hole 5 to form a full pipe water flow with a large flow rate, and the full pipe water flow passes through the basin bottom outlet 11 and the soaking section 17 quickly squeezes the air in the pipe of the negative pressure area 16. When the water flow approaches the water resistance bend 14, a moment of deceleration or waiting exists, at this moment, the water level difference between the water flow in the eccentric joint 13 and the water flow in the negative pressure area 16 is the largest, the flow speed of the water resistance bend 14 section is faster and faster due to the attraction force and potential energy difference acting force between the water flow liquid molecules, the negative pressure in the negative pressure area 16 is greater and the replacement speed of the sewage inlet 3 is faster and the siphon force is greater and faster. When the water supply to the water inlet 2 is stopped, the air is sucked in when no water is available at the sewage inlet 3, and thus the negative pressure in the negative pressure area 16 is eliminated, and the siphon process is stopped.

The siphon squatting pan sleeved with the siphon blow-off pipe can be changed and modified without limitation to the specific structure of the embodiment, such as multiple changes of the whole structure of the siphon blow-off pipe, various changes of the ceramic interface of the squatting pan and the like. In summary, the protection scope of the siphon squatting pan sleeved with the siphon drain pipe also comprises the exchange, the substitution and the modification obvious to those of ordinary skill in the art.
