Description

Automatic sequential flushing device for water closets

technical field

The utility model belongs to the field of sanitary ware, in particular to a flushing device for a flush toilet.

Background technique

In domestic water, toilet water consumption accounts for 60% to 70% of domestic water consumption, and flush toilet is the facility with the largest water consumption in the toilet. At present, the flush toilets in family bathrooms generally use a single-tank water tank, flushed with tap water, and the water consumption for one flush is about 6L-10L, so the tap water consumption is relatively large. In order to save water resources and realize the recycling of water resources, some communities have built reclaimed water systems to treat slightly polluted water in the community and reuse it for water features, greening, and flushing toilets in the community; The waste water after washing vegetables, face and feet is used for flushing toilets. Compatible with this water-saving measure, a double-tank flush toilet (such as ZL 03221322.0, ZL 200620044093.9, etc.) has appeared. The flushing device of this type of flush toilet has two water tanks—clean water tank and waste water tank. The clean water tank is connected to the external tap water pipe , the waste water tank is communicated with the external secondary water (or reclaimed water, waste water) inlet pipe, the two water tanks are respectively provided with mutually independent water discharge devices, and the outlet pipes of the two water discharge devices are all communicated with the flushing chamber of the toilet body. When the water in the waste water tank is enough to flush the toilet, operate the water discharge device of the waste water tank to flush the toilet with waste water; when there is little or no water in the waste water tank, operate the water discharge device of the clean water tank to flush the toilet with tap water . As can be seen from the above description, the problems of the existing two-box type flush toilet and the use thereof are: 1, because the general turbidity of secondary water (or claiming reclaimed water, waste water) is relatively high and the cleanliness is low, only two After flushing with secondary water, the sealing water remaining in the toilet is still turbid after flushing, which has potential hygiene risks and poor visual perception; 2. Since the water discharge devices in the two water tanks are independent of each other, if the toilet Rinse with tap water after rinsing with secondary water, then will operate the draining device of clean water tank again, operability is relatively poor.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic sequential flushing device for flush toilets. Sewage treatment plants or sewage treatment stations in residential quarters treat up to standard discharge water, or rainwater collected in residential quarters, or washing and discarded water in households), clean water (the clear water is tap water) automatically flushes the toilet sequentially, and the water retained in the toilet Sealing water is clean water, which can achieve the same effect as washing with clean water in terms of sensory and hygiene.

The automatic sequence flushing device for flush toilet described in the utility model comprises a fresh water tank, a reclaimed water tank and a flushing start handle, and a set of water inlet control mechanism and a flushing control mechanism are respectively installed in the clean water tank and the reclaimed water tank; The flushing control mechanism, the automatic sequence flushing control mechanism is respectively connected with the reclaimed water inlet control mechanism installed in the reclaimed water tank and the clear water flushing control mechanism installed in the clean water tank; the flushing start handle is connected with the reclaimed water in the reclaimed water tank Flush control mechanism connection.

The reclaimed water inlet control mechanism installed in the reclaimed water tank is a float valve, and the clear water flushing control mechanism installed in the clean water tank is a leather plug II. The automatic sequential flushing control mechanism has two structures, one is a fixed pulley structure, and the other is a lever structure. The fixed pulley structure is composed of a pulley and a pulley II wound on the pulley. The pulley is installed on the partition between the fresh water tank and the reclaimed water tank. One end of the pulley II is connected to the float I of the float valve located in the reclaimed water tank. The other end is connected with the leather plug II in the clean water tank. The lever structure consists of a lever II and a pull wire III connected to both ends of the lever II. The fulcrum of the lever II is located on the partition between the clean water tank and the reclaimed water tank. Connection, the stay wire III at the other end of the lever II is connected with the leather plug II in the clean water tank.

Since the outlets of both the reclaimed water tank and the clean water tank are connected to the flush chamber of the flush toilet, when the reclaimed water tank drains, it will take away part of the air in the drain pipe of the clean water tank, forming a negative pressure in the drain pipe, but the clean water overflow pipe in the clean water tank makes the clean water The drain port of the tank communicates with the atmosphere, thereby eliminating the influence of negative pressure, and will not affect the start-up of the linkage drainage of the middle water tank and the clean water tank.

The working method of the automatic sequential flushing device for flush toilets described in the utility model: when flushing the flush toilets, pull the start handle positioned at one side of the reclaimed water tank by hand, then the leather plug I in the reclaimed water tank is lifted, and the reclaimed water tank starts Drainage; when the floating ball I in the middle water tank falls to the set height, under the action of the automatic sequential flushing control mechanism, the leather plug II in the clean water tank is lifted, and the clean water tank starts to drain water, and at the same time, the water inlet control valve of the middle water tank is opened , the reclaimed water tank starts to take in water; when the water discharge in the reclaimed water tank ends, the leather plug I falls back, the water level in the reclaimed water tank rises, and the float I in the reclaimed water tank rises to the set position, then the water inlet control valve is closed to stop water inflow; when the clear water tank When flushing starts, the floating ball II drops, its water inlet control valve opens, and the clean water tank begins to take in water; when the water discharge in the clean water tank is completed, the leather plug II falls back, and the water level of the clean water tank rises; when the floating ball II in the clean water tank rises to When the position is set, the water inlet control valve is closed, the water inlet is stopped, and the initial state before use is restored.

What needs to be explained is: in order to prevent the problem that the toilet cannot be flushed when the reclaimed water supply is insufficient, the water inlet pipe of the reclaimed water tank can be connected to the reclaimed water delivery pipe and the tap water pipe respectively through a three-way joint, so as to supply tap water when the reclaimed water supply is insufficient. In communities without a reclaimed water system, domestic waste water such as household laundry and vegetable washing can be used as the water source for the reclaimed water tank. The specific implementation can use the "combined water-saving sanitary ware" described in ZL 200620071387.0 or the "use of reclaimed water" described in ZL 200620072998.7. The technical solutions provided by patents such as "water-saving flushing system".

The automatic sequence flushing device described in the utility model can be used for all sanitary ware that adopts water tank flushing except being applicable to flush toilets.

The utility model has the following beneficial effects:

1. Since the automatic sequential flushing control mechanism is set, and the flushing start handle is connected to the flushing control mechanism in the reclaimed water tank, the toilet can be flushed sequentially with reclaimed water and clean water in one operation, which is very convenient to use.

2. Rinse the toilet with reclaimed water and clean water sequentially, which is not only beneficial to water saving, but also can keep the sealed water as clean water, and achieve the same effect of completely flushing with clean water in terms of sensory and hygiene.

3. The device described in the utility model has a simple structure, is easy to manufacture, and is convenient for industrial production.

Detailed ways

Below in conjunction with the accompanying drawings, the structure of the automatic sequential flushing device for flush toilets described in the present invention will be further described.

Example 1

In this embodiment, the structure of the automatic sequential flushing device used for flush toilets is shown in Figure 1, including a reclaimed water tank 8, a fresh water tank 16, a flushing start handle 1, an automatic sequential flushing control mechanism, and a middle water tank installed in the reclaimed water tank. Water inlet pipe 6, reclaimed water overflow pipe 7, reclaimed water inlet control mechanism and reclaimed water flushing control mechanism, clean water inlet pipe 13 installed in the clean water tank, clean water overflow pipe 14, clean water inlet control mechanism and clean water flushing control mechanism. The reclaimed water flushing control mechanism is composed of a lever I2, a pull wire I3, and a leather plug I4. The lever I2 is hinged to the wall of the reclaimed water tank 8. One end of the lever I2 is connected to the flush start handle 1, and the other end is connected to the pull wire I3. The pull wire I3 Connect with plug I4. The reclaimed water inlet control mechanism is a ball float valve, which is mainly composed of a water inlet control valve installed on the reclaimed water inlet pipeline and a float ball I5 hinged with the valve body. The clean water flushing control mechanism is composed of a leather plug II11; the clean water inlet control mechanism is a float valve, which is mainly composed of a water inlet control valve installed on the clean water inlet pipeline and a float ball II12 hinged with the valve body. The automatic sequential flushing control mechanism is a fixed pulley structure, which is composed of a pulley 9 and a backguy II10 wound on the pulley. The pulley 9 is installed on the partition 15 between the middle water tank 8 and the clean water tank 16. One end of the backguy II10 is connected to the The float I5 of the float valve of the water tank is connected, and the other end of the pull wire II10 is connected with the leather plug II11 in the clean water tank.

In order to illustrate that the automatic sequential flushing control mechanism can automatically control the lifting of the leather plug II in the clean water tank, the force analysis of the floating ball I in the middle water tank and the leather plug II in the clean water tank is carried out below in conjunction with Fig. 2 and Fig. 3 .

As shown in Figure 2, the middle water tank 8 is 200mm long, wide 150mm, and high 200mm, and the clean water tank 16 is long 100mm, wide 150mm, and high 200mm, and the volume ratio of the middle water tank and the clean water tank is 2: 1; The height of the water level is 150mm; the ball radius R of the floating ball I5 in the middle water tank is 35mm; when the water level of the middle water tank 8 was 150mm, the distance between the ball center of the floating ball I5 and its ball handle hinge was 120mm, and the distance of the floating ball I5 The distance between the center of the sphere and the dividing plate 15 is 50mm.

When the ball center of the floating ball I5 in the middle water tank 8 falls to 50 mm apart from the bottom of the tank, the stay wire II10 wound on the pulley is tightened, and the leather plug II11 in the clean water tank 16 is in a pulled state. At this moment, the floating ball in the middle water tank 8 The ball I5 is affected by the gravity G, the pulling force T1 of the pull wire II10 and the pulling force T2 of the float handle, ignoring the weight of the leather plug II11, the skin plug II in the fresh water tank 16 is only affected by the hydrostatic pressure F and the pulling force T of the pull wire II10, The force analysis is shown in Figure 3.

Due to the small volume of the clean water tank, the diameter of the leather plug II11 in the clean water tank 16 is 20 mm. When the water level of the clean water tank is 150 mm, the hydrostatic pressure F received by the skin plug II is:

F=PA=ρghA=1000×9.8×0.15×3.14×0.01 ² =0.462(N)

In the formula, ρ-the density of water, kg/m ³

g-gravitational acceleration, m/s ²

h- object submerged depth, m

A-The compression area of the object, m ²

When the water level of the clean water tank is 150mm, the leather plug II is subjected to a vertical upward pulling force T=F=0.462(N),

According to the fixed pulley transmission principle, the pulling force T1≈T=0.462 (N) of the pull wire II10 received by the floating ball I5 in the middle water tank 8,

When the floating ball I5 in the middle water tank 8 drives the backguy II10 wound on the pulley 9 to fall, the gravity suffered by the floating ball I should be greater than or equal to the vertical upward resultant force provided by the floating ball handle and the backguy II.

When the size of the water tank is shown in Figure 2, the component force in the vertical direction of the pulling force T ₁ of the pull wire II on the floating ball I is calculated to be 0.356N, and the component force in the horizontal direction is calculated to be 0.295N. The pull force T ₂ of the float handle is 0.695N, the component force in the horizontal direction of T ₂ is 0.295N, and the component force in the vertical direction is 0.445N. The floating ball 15 in the middle water tank 8 is subjected to the power of the vertical upward direction and is altogether: 0.356+0.445=0.801 (N). Therefore, as long as the gravity G of the floating ball I is greater than or equal to 0.801N, it can be guaranteed that when the floating ball I in the middle water tank falls to the set position, the pull wire II can lift the leather plug II11 in the clean water tank 16 to achieve automatic Purpose of sequential flushing.

If the diameter of the float 1 in the middle water tank is 70mm, it must be guaranteed in the design that when the water level of the middle water tank reaches the design water level, the float 1 floats and can close the water inlet control valve. The buoyancy force of the floating ball I5 with a diameter of 70mm when half of the ball is below the water surface at the design water level is:

In the formula, ρ-liquid density, kg/m ³

g-gravitational acceleration, m ² /s

V - the volume of water displaced by the object, m ³

It can be seen that F _float >G, when the gravity G of the float I5 is 0.801N, the float I can float at the design water level.
