Description

Toilet bowl

Technical Field

The utility model relates to a bathroom field, concretely relates to closestool.

Background

The toilet bowl is also called a toilet bowl and is a covered bucket for relieving the bowels. The utility model of the closestool is called as a great utility model, and solves the problem that people eat and drink and pull the toilet. The flushing principle of the toilet bowl on the market at present is basically two main types of direct flushing type and siphon type. The siphon type is divided into vortex type siphon and jet type siphon.

The direct flushing toilet discharges dirt by utilizing the impulsive force of water flow, and generally, the wall of a pool is steep, the water storage area is small, so that the water power is concentrated, and the dirt flushing efficiency is high. Its advantages are simple flushing pipeline, short path, large diameter (9-10 cm), and short flushing course. Compared with a siphon type toilet, the direct flushing type toilet is easy to flush larger dirt due to no water return bend, and is not easy to block in the flushing process. The biggest defects of the deodorant are that the flushing sound is large, and the deodorization function is poor, so that the product varieties are few in the market at present.

The siphon toilet is characterized by that the drainage pipeline is made into the form of S-shaped, after the drainage pipeline is filled with water, a certain water level difference can be produced, and the suction force produced in the drainage pipeline can be used for removing sewage, in fact, the suction force is produced by means of Bernoulli principle. To create the bernoulli effect, siphonic toilets first drain water to a very high level and the waste pipes cannot be too large, thus ensuring that the pipes are completely filled with water and do not retain air. Thus, a first significant drawback of siphonic toilets is the relative water consumption, which is at least 8 liters to 9 liters each, or even more than ten liters. The second obvious disadvantage is that the siphon type water discharge pipe has the diameter of only 5 to 6 centimeters, is easy to block during flushing, and causes great inconvenience in life.

The siphon type toilet bowl is also divided into a vortex type siphon and a jet type siphon. The flushing port of the vortex type siphon is arranged on one side of the bottom of the toilet bowl, and water flow forms vortex along the wall of the pool during flushing, so that the flushing force of the water flow on the wall of the pool is increased, the suction force of the siphon action is also increased, and the dirty in the toilet bowl is discharged. The jet type siphon adds a jet auxiliary channel at the bottom of the toilet bowl, which is aligned with the center of the sewage outlet, when flushing, part of water flows out from the water distribution holes around the toilet seat, and the other part is sprayed out from the jet orifice.

The siphon type pedestal pan has the greatest advantage of low flushing noise, which is called silence. In terms of the dirt flushing capacity, the siphon type toilet is easy to flush away dirt adhered to the surface of the toilet, and the siphon type toilet has higher water storage capacity and better deodorization effect than the direct flushing type toilet. Therefore, siphon type toilet bowls in the market are various in variety, and more choices are provided for buying the toilet bowls.

From their respective principles, the motive force for flushing, whether direct flush or siphon, comes from the potential energy of the water stored in the tank prior to flushing. This principle brings about two disadvantages. Firstly, the toilet bowl must have a water tank higher than the plane of the toilet bowl, which not only affects the beauty of the toilet bowl, but also generates certain sanitary dead angles, which is not beneficial to health. Secondly, the height of the tank cannot be too high, currently typically in the range of tens of centimeters, due to space and aesthetic limitations. From life experience, no matter the toilet bowl is of a direct flushing type or a siphon type, the water level difference in the range cannot meet the drainage requirement under certain conditions, and the phenomenon of toilet bowl blockage often occurs.

The main disadvantages of the existing toilet bowl are shown in the following aspects. Firstly, the presence of the water tank cannot be avoided, which affects the beauty and hygiene of the toilet. Secondly, the water pumping force generated by the water level difference is small, the probability of blockage of the closestool is high, and the quality of daily life is influenced. Third, relatively waste water.

Therefore, it is necessary to develop a toilet that uses a small amount of water, prevents clogging of the toilet, and flexibly sets the position of the water tank.

The information disclosed in this background section of the invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

According to an aspect of the present invention, there is provided a toilet bowl, including: the toilet comprises a urinal, a bent pipe communicated with the bottom of the urinal, a sewer pipe connected to the other end of the bent pipe, a sealing door arranged at the joint of the sewer pipe and the bent pipe, and a combustion chamber;

Specifically, when the device is used, fuel gas (various hydrocarbon fuels, such as natural gas and the like) with a certain equivalent ratio is injected into the combustion chamber, the fuel gas is mixed with air, when dirt in the urinal needs to be removed, the mixed gas is ignited, the combustion chamber is kept sealed in the combustion process except for the communication of the combustion chamber with the pipeline between the elbow and the sewer pipe, and the combusted high-pressure gas is exhausted to the sewer pipe through the pipeline and the elbow. This process will exhaust most of the combustion chamber air. When the pressure of the combustion chamber is balanced with the pressure of the downcomer, the pressure of the residual gas in the combustion chamber is about 1 atmosphere, and the density is greatly reduced; then, under the negative pressure state of the combustion chamber, the closing door is closed rapidly under the action of the air power, and the passage between the toilet bowl and the sewer pipe is cut off. Dirt in the excrement pool enters the bent channel under the action of the pressure difference between the external atmospheric pressure and the negative pressure of the combustion chamber, and gas in the bent channel enters the combustion chamber. The combustion chamber pressure gradually increases as the gas in the elbow continues to enter the combustion chamber. When all the substances in the urinal cross the topmost end of the S channel and the substances in the urinal do not reach the communication part of the combustion chamber and the bent pipe, the pressure of the combustion chamber is high enough, and the closing door is automatically opened. The dirt entering the bend enters the sewer pipe under the action of gravity.

Further, the elbow is an S-shaped elbow, the S-shaped elbow is horizontally arranged, and the highest point of the S-shaped elbow is higher than the lowest point of the urinal.

Furthermore, the combustion chamber is connected with the S-shaped elbow, and an air injection orifice is arranged at the joint of the combustion chamber and the S-shaped elbow.

Furthermore, the air injection spray hole is a Laval spray pipe, the horizontal height of one end, positioned on the combustion chamber, of the Laval spray pipe is higher than that of the other end of the Laval spray pipe, and the included angle between the Laval spray pipe and the axis of the elbow pipe is 5-30 degrees.

Specifically, in order to avoid adverse effects of high pressure on discharged matters in the urinal when gas is discharged to the sewer pipe, the air injection nozzle is designed into a Laval nozzle form (a contraction-expansion nozzle) according to the aerodynamic principle, so that the high speed of the gas outlet is ensured, and even the speed of sound is exceeded; meanwhile, the axis of the air injection spray hole and the axis of the sewer pipe form a certain angle, so that the injection effect of the injection airflow on the gas in the sewer pipe is maximized, and the spray pipe can generate ultrahigh-speed airflow.

Furthermore, the water-spraying device also comprises a water-spraying nozzle, wherein the water-spraying nozzle is arranged in the combustion chamber and is communicated with a water supply pipeline. And after the combustion is finished and the exhaust is finished, the thermodynamic state of the combustion chamber is normal pressure and high temperature, and water mist is sprayed into the combustion chamber through the water mist spray head, so that the temperature of the combustion chamber is reduced to normal temperature.

The ignition device further comprises a spark plug and a control button, wherein the spark plug is arranged in the combustion chamber, and the control button is arranged outside the combustion chamber and is electrically connected with the spark plug.

Specifically, the spark plug may be powered mechanically without a separate power supply system.

Furthermore, the urinal also comprises a water storage tank which is arranged on one side of the urinal and communicated with the urinal.

Specifically, the water storage tank is arranged for adding clean water into the urinal after the sewage in the urinal is discharged, so that the reverse smell of the elbow is prevented, the use is cleaner and tidier, and the position of the water storage tank can be flexibly set due to the fact that the pressure sewage discharge of the water storage tank is not needed. More preferably, when the toilet of the present application is used in home decoration, since the water column pressure is not required for discharging the waste, the toilet water pipe may be directly connected to the urinal for adding clean water.

According to the utility model discloses a control method of kind closestool includes:

when the dirt in the urinal needs to be removed, combustible gas is injected into the combustion chamber;

the igniter ignites and leads the combustible gas to deflagrate in the combustion chamber, and the deflagrated high-temperature high-pressure gas is exhausted to the S-shaped bend and the sewer pipe through the pipeline. In order to prevent the high-pressure gas from generating adverse effects on the dirt in the urinal in the emptying process, the air injection spray hole is a Laval spray pipe, and an included angle between the Laval spray pipe and the axis of the elbow pipe is 5-30 degrees, so that the high-pressure air has an ultrasonic velocity at the outlet of the spray pipe and performs an injection effect on the dirt in the urinal;

after the high-temperature high-pressure gas is exhausted, the residual gas in the combustion chamber is in a normal-pressure high-temperature state;

the water mist spray head sprays water mist to the residual gas in the combustion chamber under normal pressure and high temperature state, and the residual gas is changed from normal pressure and high temperature to negative pressure and normal temperature;

As shown in fig. 1, the toilet bowl includes: the urinal 1 is communicated with a bent pipe at the bottom of the urinal 1, a sewer pipe 3 connected to the other end of the bent pipe, a sealing door 4 arranged at the joint of the sewer pipe 3 and the bent pipe, and a combustion chamber 5;

the combustor also comprises a gas pipeline 8 communicated with the combustion chamber 5, and the combustion chamber 5 is communicated with the elbow through a pipeline;

wherein, when the combustion chamber 5 is in a negative pressure state, the closing door 4 cuts off the passage between the elbow pipe and the downcomer pipe 3.

The bent pipe is an S-shaped bent pipe 2, the S-shaped bent pipe 2 is horizontally arranged, and the highest point of the S-shaped bent pipe 2 is higher than the lowest point of the urinal 1.

The combustion chamber 5 is connected with the S-shaped elbow 2, and an air injection orifice 6 is arranged at the joint.

The Laval nozzle 6 is located at one end of the combustion chamber 5, the horizontal height of the Laval nozzle is higher than that of the other end of the Laval nozzle 6, and an included angle between the Laval nozzle 6 and the axis of the elbow is 5-30 degrees.

The water-saving combustion chamber is characterized by further comprising a water mist spray head, wherein the water mist spray head is arranged in the combustion chamber 5 and is communicated with a water supply pipeline 7.

The ignition device further comprises a spark plug 9 and a control button, wherein the spark plug 9 is arranged in the combustion chamber 5, and the control button is arranged outside the combustion chamber 5 and is electrically connected with the spark plug 9.

The top of the downcomer 3 is provided with a transition part, the width of the top of the transition part is larger than the width of the bottom of the transition part, the width of the top of the transition part is matched with the rotating radius of the sealing door 4, and the width of the bottom of the transition part is matched with the diameter of the downcomer 3.

The urinal also comprises a water storage tank, wherein the water storage tank is arranged on one side of the urinal 1 and is communicated with the urinal 1.

The control method of the toilet can be divided into five steps.

First, fuel gas (various hydrocarbon fuels, such as natural gas, etc.) is injected into the combustion chamber, and the fuel gas is mixed with air and combusted. According to the nature of common hydrocarbon fuels, the adiabatic constant volume pressure after combustion is about 7-8 atm under the equivalence ratio of 1. Except the pipeline communication between the combustion chamber and the sewer pipe, the combustion chamber is kept sealed in the combustion process, and the high-pressure gas after combustion is exhausted to the sewer pipe through the air injection spray hole. This process will exhaust most of the combustion chamber air. When the pressure of the combustion chamber is balanced with the pressure of the downcomer, the pressure of the residual gas in the combustion chamber is 1 atmosphere, and the density is greatly reduced. The equivalent ratio of the components is about 1/8-1/7 of the atmospheric density at normal temperature and normal pressure under the condition of 1.0. In order to avoid adverse effects of high pressure on excrement in the toilet bowl when gas is exhausted to the downpipe, the air injection nozzle is designed into a Laval nozzle form (a contraction-expansion nozzle) according to the aerodynamic principle, and the high speed of the gas outlet is ensured, even exceeds the sound speed; meanwhile, the axis of the air injection spray hole forms a certain angle with the axis of the sewer pipe, so that the injection effect of the injection airflow on the gas in the sewer pipe is maximized.

Secondly, the thermodynamic state of the combustion chamber is normal pressure and high temperature after the combustion is finished and the exhaust is finished, and at the moment, water mist is sprayed into the combustion chamber through a water mist nozzle, so that the temperature of the combustion chamber is reduced to normal temperature. According to the ideal gas state equation, the pressure of the combustion chamber is greatly reduced after the step is finished, and the specific value is determined by the equivalence ratio, so that the equivalence ratio of the injected fuel gas is a main parameter for adjusting the pumping pressure. The equivalent ratio is about 1/8-1/7 at 1.0 atmosphere.

Thirdly, under the negative pressure state of the combustion chamber, the sealing door is closed rapidly under the action of air power to cut off the passage between the S-shaped elbow and the sewer pipe. The contents of the bowl will be subjected to a pressure differential between the ambient atmospheric pressure and the negative pressure in the combustion chamber, which is the source of the toilet bowl suction, and which is sized according to the equivalence ratio. Under the condition of an equivalence ratio of 1.0, the pressure difference is about 8 meters of high water column and far greater than tens of centimeters provided by the existing water tank. Under the action of the pressure difference, the substances in the toilet bowl enter the S-shaped bend, and the gas in the S-shaped bend enters the combustion chamber. In the step, in order to improve the actuating efficiency of the sealing door, a certain angle is formed between the plane of the sealing door and the central line of the sewer pipe.

Fourthly, because the gas of the downcomer continuously enters the combustion chamber, the pressure of the combustion chamber gradually increases. Through the design, the situation that no non-gas substances in the toilet bowl reach the air injection spraying hole when all substances in the toilet bowl cross the topmost end of the S-shaped curve is ensured, and the pressure of the combustion chamber is high enough so that the sealing door is automatically opened. This is achieved by adjusting the ratio of the S-turn, the bowl volume and the combustion chamber volume.

Fifthly, the material entering the S-shaped bend enters a sewer pipe under the action of gravity.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
