Description

Pre-stored water closestool

Technical Field

The utility model relates to a sanitary wares technical field, concretely relates to water closet reserves.

Background

In the prior art, a washing ring water channel of a common siphon closestool is communicated with a jet pipeline, after washing, air can enter the jet pipeline from an overflow pipe or a washing ring washing hole, and water in the jet pipeline can flow out from a jet hole at the bottom until the water level in the jet pipeline is reduced to the height of a trap water seal; at this time, since the portion of the injection pipe above the water seal is filled with gas, water flowing down from the water tank is mixed with the gas inside the pipe and stirred to discharge the air at the time of the next flushing, but this process has problems of large energy loss, large noise, slow siphon formation, and the like.

In order to solve the above problems, a toilet capable of pre-storing water in the spray pipe has been proposed, in which air cannot enter the spray pipe by changing the structure of the toilet, so that the interior of the spray pipe after being flushed can be ensured to be still filled with water, thereby avoiding the above problems.

However, the toilet bowl with the water storage in advance by the injection pipe has other problems besides the problem of air discharge which has been solved:

(1) because the jet pipeline of the closestool with the jet pipeline capable of storing water in advance is communicated with the trap, and the water in the trap can be polluted by the excrement of a human body, the water in the jet pipeline and the water in the trap are similar and belong to water with poor water quality;

however, during the opening and closing of the drain valve, the water in the tank may be polluted due to the direct contact of the valve plate of the first drain valve with the water in the injection pipe or due to the backflow phenomenon of the water in the injection pipe occurring at the moment when the first drain valve is opened.

(2) In the later flushing period of the toilet, the suction force of the siphon pipe can pump away some water in the trap, so that water needs to be supplemented to the trap in order to ensure a sufficient water seal height;

when the problem is solved, a path of water is led out from a water inlet valve and injected into an overflow pipe, the water flows into a water guide pipeline along the overflow pipe, the water guide pipeline is divided into two paths, one path of water flows to a washing ring water channel, and the other path of water flows to a jet orifice at the bottom; because the height of the washing ring is high and the water supplement amount is small, the supplement water cannot flow out from the washing hole of the washing ring water channel, only flows downwards from the jet orifice and is injected into the trap, and because the water is positioned under the water cover from the jet orifice, the process is difficult to be perceived by users;

in the case of toilets in which the jet pipe can store water, the overflow pipe is generally closed in order to ensure that air does not enter the jet pipe; because negative pressure exists in the injection pipeline, direct water replenishing is difficult, and water replenishing is generally tried to be injected into the washing ring water channel, so that the water replenishing flows out of the washing hole of the washing ring water channel and flows into the trap along the surface of the pot;

however, the above technical scheme still has two defects, one of which is that when the water supplement flows into the trap along the pan surface, the process generally lasts for 5-10s, so that the user is liable to misunderstand that the inside of the water tank has a fault; secondly, after the toilet bowl is used for a long time, yellow scale can be left on the pan surface due to the fact that water is supplemented to flow through the pan surface for a long time, and a user needs to manage the toilet bowl frequently, so that the user experience can be affected.

(3) After the drainage of the common siphon closestool is closed, air can enter the jet pipeline from the flushing hole and the overflow pipe of the washing ring water channel, so that water in the jet pipeline can continuously flow out from the jet opening at the bottom, further, dirt near the jet opening is pushed into the siphon pipeline, and then the dirt is taken away by utilizing the water flow of the siphon pipeline;

however, in the case of a toilet with a pre-stored water injection pipeline, after the water discharge valve is closed, air cannot enter the injection pipeline from the toilet seat or the overflow pipe, so that water in the injection pipeline cannot continuously flow out from the injection port at the bottom, and further, dirt near the injection port cannot be pushed forward into the siphon pipeline; in addition, after the drainage valve is closed, no water flows into the trap from the injection port any more, so the duration of siphon is shortened, and the overall flushing effect of the toilet is affected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above-mentioned defect or the problem that exist among the background art, provide a water closet reserves water in advance to when solving first drain valve and opening, the problem that the moisturizing can't be followed the injection of jet injection trap is further still solved to the water pollution water tank in the injection pipeline.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

Based on the fourth technical scheme, still be equipped with fifth technical scheme, in fifth technical scheme, the wash ring water course pass through the second drain valve directly with the water tank intercommunication.

Based on fourth technical scheme, still be equipped with sixth technical scheme, in sixth technical scheme, the wash circle water course pass through check valve intercommunication injection pipeline, the check valve lose water pressure and close when first drain valve is closed.

Based on any one of the first technical scheme to the sixth technical scheme, a seventh technical scheme is further provided, and in the seventh technical scheme, the highest point of the communication part of the spraying branch pipe and the spraying pipeline is about 10mm-50mm lower than the water cover.

On the basis of any one of the first to sixth technical solutions, an eighth technical solution is further provided, wherein in the eighth technical solution, the equivalent diameter of the minimum cross-sectional area of the jet branch pipe is between 6 and 25 mm.

As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following advantages:

1. because the pre-stored water closet is provided with the injection branch pipe, the higher end of the injection branch pipe is communicated with the atmosphere, the other end of the injection branch pipe is communicated with the bottom of the injection pipeline, and the highest point of the communicated part is lower than the water cover of the closet, when the injection drain valve is opened, water flow flowing into the injection pipeline enters the injection branch pipe from bottom to top under the action of high pressure formed at the bottom of the injection pipeline, when the injection drain valve is closed, the high pressure at the bottom of the injection pipeline disappears, the injection branch pipe is communicated with the trap, water flows into the trap with low water level from the injection branch pipe with high water level to replenish the trap, and sewage of the trap is pushed into the pipeline in a siphon manner, meanwhile, air in the injection branch pipe can form bubbles to float upwards to the bottom of the first drain valve to form an air layer of the isolation water tank under the action of buoyancy, and water in the injection pipeline, which is divided after the, stopping until the liquid level of the water cover of the toilet bowl is over the highest point of the communication part of the injection branch pipe and the injection pipeline; therefore, the arrangement can play a role in pushing dirt near the jet orifice, preventing water in the jet pipeline from polluting the water tank when the first drain valve is opened and supplementing a small amount of water to the trap.

2. Because when the water tank moisturizing, spray the branch pipe and also the moisturizing, consequently the moisturizing can enter into the trapway through spraying the branch pipe to carry out the moisturizing to the trapway.

3. One end of the overflow pipe extends out of the highest working water level of the water tank and is communicated with the atmosphere, and the other end of the overflow pipe is communicated with the jet branch pipe, so that water can enter the jet branch pipe through the overflow pipe to supplement water to the trap, and further, the water seal height is enough; thus, this arrangement provides a specific embodiment to solve the problem that the jet pipe can pre-trap refill water for the toilet from the jet port into the trap.

4. Because the overflow pipe is communicated with the washing ring water channel, the jet branch pipe is communicated with the atmosphere through the communicated washing ring water channel, and the jet branch pipe is closer to the overflow pipe than the washing hole of the washing ring water channel, the supplemented water flowing in from the overflow pipe cannot flow out from the washing hole of the washing ring water channel before smoothly flowing into the jet branch pipe; therefore, the arrangement further ensures that the water replenishing can enter the injection branch pipe through the overflow pipe, and further realizes the water replenishing to the trap.

5. Because the washing ring water channel is isolated from the injection pipeline, and a second drain valve is arranged between the washing ring water channel and the water tank, when the first drain valve is closed, air does not enter the injection pipeline through a washing hole of the washing ring water channel; this arrangement thus ensures that the spray line can be filled with water after the flushing.

6. The washing ring water channel is communicated with the injection pipeline through the one-way valve, and the one-way valve loses water pressure to be closed when the first water discharge valve is closed, so that the washing ring water channel and the injection pipeline can be isolated from each other when the first water discharge valve is closed, and air cannot enter the injection pipeline from a washing hole of the washing ring pipeline; this arrangement thus provides another embodiment which ensures that the spray line can be filled with water after flushing.

7. The highest point of the communication part of the spraying branch pipe and the spraying pipeline is set to be 10mm-50mm lower than the water cover, so that enough water seal is ensured in a normal state, and a certain amount of gas can enter the spraying pipeline in the later stage of flushing.

8. The equivalent diameter of the minimum cross section area of the spraying branch pipe is set between 6 mm and 25mm, so that the amount of gas entering the spraying pipeline from the spraying branch pipe can be controlled within a certain range, and further, the phenomenon that the reserved water inside the spraying pipeline is lost too much due to excessive air intake is avoided; therefore, the arrangement ensures that the injection pipeline cannot completely lose the water storage in the trap while replenishing water to the trap, and further influences the next flushing effect.

Referring to fig. 1 to 5, a toilet 1 with pre-stored water according to a first embodiment of the present invention is shown, which is provided with a spray pipe 11, a spray branch pipe 12, a wash ring water channel 13, a first drain valve 21, a second drain valve 22, an overflow pipe 23, a water inlet valve (not shown in the figure) and a water replenishing pipe 24;

the spraying pipeline 11 is used for washing the bottom of the closestool 1, a first drainage valve is arranged between the top of the spraying pipeline and the water tank 2, and a spraying opening 110 is arranged at the bottom of the spraying pipeline;

the equivalent diameter of the minimum cross section area of the spraying branch pipe 12 is between 6 and 25mm, the higher end of the spraying branch pipe is communicated with the atmosphere, the other end of the spraying branch pipe is communicated with the bottom of the spraying pipeline 11, and the highest point of the communicated part is about 10 to 50mm lower than the water cover of the closestool 1;

one end of the overflow pipe 23 extends out of the highest working water level of the water tank 2 and is communicated with the atmosphere, and the other end of the overflow pipe is communicated with the injection branch pipe 12;

the washing ring water channel 13 is communicated with the overflow pipe 23 and the injection branch pipe 12, so that the injection branch pipe 12 is communicated with the atmosphere through the washing ring water channel 13; the spray branch pipe 12 is closer to the overflow pipe 23 than the washing hole of the washer channel 13; the water tank 2 is communicated with the washing ring water channel 13 through a second drain valve 22;

the water replenishing pipe 24 is used for replenishing water to the injection branch pipe 12 when the water tank 2 replenishes water, in the embodiment, the water replenishing pipe 24 is connected with a water inlet valve and replenishes water to the overflow pipe 23, so that the replenished water flows into the overflow pipe 23, then sequentially flows through the washing ring water channel 13 and the injection branch pipe 12 and then flows into the trap, and the trap is replenished with water;

as shown in fig. 2, when the toilet is in the initial state, the first drain valve 21 and the second drain valve 22 are both in the closed state, and the water tank 2, the inside of the injection pipeline 11 and the traps in the basin are all filled with water;

as shown in fig. 3, when the toilet is in the middle stage of flushing, the first and

second discharge valves

21 and 22 are opened, and the inlet valve is opened after the water level of the water tank 2 drops;

when the water inlet valve is opened, water is supplemented to the water tank 2, so that the injection pipeline 11, the injection branch pipe 12 and the washing ring water channel 13 can be always in a water-full state, and the water supplementing pipe 24 supplements water to the overflow pipe 23, and water flowing in along the overflow pipe 23 sequentially flows through the washing ring water channel 13 and the injection branch pipe 12 and finally flows into the trap;

when the second drain valve 22 is opened, the water in the water tank 2 also flows into the wash ring water channel 13, so that the water in the filled wash ring water channel 13 flows out of the flushing hole of the wash ring water channel 13 and then flows to the trap along the pelvic surface;

when the first drain valve 21 is opened, the water in the water tank 2 flows into the injection pipeline 11 and flows out from the injection port, wherein a part of the water flow flowing out from the injection port generates a larger pressure at the bottom of the injection pipeline 11 due to the limited flow capacity of the injection port 110, and enters the injection branch pipe 12 from bottom to top under the action of the water pressure, and after the injection branch pipe 12 is filled, a part of the water flow enters the washing circle water channel 13;

part of water flow enters the siphon pipeline under the action of injection, so that water in the trap is sucked away due to the accelerated flow of the siphon pipeline;

the rest of the water flow flows into the trap smoothly, but the water absorption speed is increased due to the continuous enhancement of the siphon force of the siphon pipeline, so that the water level of the trap begins to drop gradually even if the water in the injection pipeline 11 and the washing ring water channel 13 continuously flows into the trap;

as shown in fig. 4, when the toilet is in the later stage of flushing, the first drain valve 21 is closed, the second drain valve 22 is closed when the first drain valve 21 is closed or after being closed, and the water inlet valve is still in an open state;

after the first drain valve 21 is closed, air cannot enter the jet pipeline 11 from the flushing hole of the washing ring water channel 13 and the overflow pipe 23 because the jet pipeline 11 and the washing ring water channel 13 are isolated from each other, so that water in the jet pipeline 11 cannot flow out from the jet opening, water flowing into the trap from the jet opening is suddenly reduced to be close to zero, and the water level of the trap is rapidly reduced even lower than the jet opening under the continuous suction action of the siphon pipeline;

however, after the first drain valve 21 is closed, the high pressure at the bottom of the injection pipeline 11 disappears, so that communication is formed between the injection branch pipe 12 and the trap, so that water can flow into the trap with a low water level from the injection branch pipe 12 with a high water level to replenish the trap, and because the water flow flows into the trap from the injection port, the flow process continues the water flow at the injection port which is interrupted so as to push the dirt in the trap into the siphon pipeline;

after the water level of the spraying branch pipe 12 is reduced, air enters the spraying branch pipe 12 from the overflow pipe 23 and the flushing hole of the washing ring water channel 13, bubbles are formed under the action of the buoyancy of water and enter the spraying pipeline 11 until the bubbles float to the bottom of the first drainage valve 21, so that an air layer for isolating the water tank 2 from the spraying pipeline 11 is formed, and the first drainage valve 21 cannot pollute the water tank due to backflow when being opened again;

after the gas in the injection branch pipe 12 enters the injection pipeline 11, the water in the injection pipeline 11 is pressed into the water trap to replenish water to the water trap, so that the water trap forms a water cover, but because the highest point of the communication part 120 of the injection branch pipe 12 and the injection pipeline 11 is lower than the water cover, the height difference between the highest point and the water cover is 10-50mm, and the equivalent diameter of the minimum cross section of the injection branch pipe 12 is 6-25mm, the air inflow entering the injection pipeline 11 from the injection branch pipe 12 is controlled to be 0.05-0.5L, and thus, the situation that the water in the injection pipeline 11 completely flows into the water trap after air inflow can be effectively avoided;

as shown in fig. 5, after the toilet is flushed, the toilet returns to the initial state again;

because the injection pipeline 11 and the wash ring water channel 13 are isolated from each other, and the respective water inlets are respectively provided with the first drain valve 21 and the second drain valve 22, when the first drain valve 21 is in a closed state, gas cannot enter the injection pipeline 11 from the flushing hole of the wash ring water channel 13, so that the injection pipeline 11 is filled with water at the moment, an isolating gas layer for isolating the injection pipeline 11 from the water tank 2 is arranged below the first drain valve 21, and the trap and the water tank 2 are also filled with water.

The pre-trap toilet in the second embodiment is different from the first embodiment in that: the overflow pipe 23 is not arranged in the water tank 2, the lower end of the spraying branch pipe 12 arranged on the closestool 1 is communicated with the bottom of the spraying pipeline 11, and the higher end is opened on the outer surface of the closestool 1 so as to be communicated with the atmosphere;

when the first drain valve 21 is closed, the high pressure at the bottom of the injection pipeline 11 disappears, so that the injection branch pipe 12 is communicated with the trap, and the injection branch pipe 12 flows into the trap to replenish water to the trap;

after the water level of the injection branch pipe 12 is reduced, because the higher end of the injection branch pipe is directly communicated with the atmosphere, air can enter the injection branch pipe 12, bubbles are formed under the action of the buoyancy of water and enter the injection pipeline 11 and float to the bottom of the first drain valve 21, so that an air layer for isolating the water tank 2 from the injection pipeline 11 is formed, and the problem that the water in the injection pipeline 11 pollutes the water tank when the first drain valve 21 is opened again is solved.

The difference between the pre-stored water closestool in the third embodiment and the first embodiment is that: the washer channel 13 is communicated with the injection pipeline 11 through a one-way valve (not shown in the figure), and the one-way valve loses water pressure to close when the first drain valve 21 is closed, so that the isolation between the injection pipeline 11 and the washer channel 13 is realized, and air is further prevented from entering the injection pipeline 11 from a flushing hole of the washer channel 13, and the injection pipeline 11 cannot realize water pre-storage.

The description of the above specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention. Modifications, equivalents and other improvements which may be made to the embodiments of the invention or to some of the technical features thereof by a person of ordinary skill in the art through logical analysis, reasoning or limited experimentation in light of the above teachings of the invention or the above embodiments are intended to be included within the scope of the invention.
