Description

water saving toilet

technical field

The utility model relates to a toilet, in particular to a water-saving toilet for household use and special occasions.

Background technique

At present, domestic household toilets generally adopt low-level open water tanks to store water to flush the toilet; drainage generally adopts the siphon principle, and the sewage in the bedpan is discharged to the sewer by the vacuum produced by the siphon.

This toilet seat commonly used by domestic families has the following deficiencies:

After the pressure water in the tap water pipe is stored in the water tank, it loses its original pressure, so when flushing, it takes more water to flush the bedpan clean.

Adopt the principle of siphon to empty the sewage in the bedpan, and to form an effective siphon, it also needs to consume more water.

Therefore, this kind of domestic toilet consumes a lot of water. Even if it is a water-saving toilet, the water consumption per flush is generally no less than 6L.

There are also some household toilets in China that use water-saving water tanks. The principle is to use the pressure of tap water to compress the sealed air during the water supply process to form pressure potential energy. When the toilet is flushed, the potential energy of the compressed air is released to pressurize the flushing water. To flush the toilet to achieve the purpose of water saving. But this water-saving water tank is not combined with the straight toilet, and the water-saving effect is not ideal.

For domestic toilets used in special occasions (such as railway passenger cars), water pumps or compressed air are generally used to pressurize the flushing water to save flushing water when flushing the toilets; this type of toilet generally does not use the principle of siphon to drain water. , but a straight-through discharge port is adopted to drain water by gravity or a specially generated vacuum. A discharge valve is installed on the toilet discharge outlet pipeline to isolate the odor. The discharge valve generally adopts a pneumatic or electric drive.

The toilet seat that this special occasion uses has following deficiency:

When water is pressurized, compressed air energy or electrical energy needs to be provided and consumed exclusively.

During the drainage process, when opening and closing the discharge valve, it is necessary to provide and consume compressed air energy or electric energy.

The flush valve is a 2-position 3-way valve.

The utility model adopts a pressure storage type water tank, which is used to store the pressure of tap water or source water, and flushes the toilet with the pressure water in the pressure storage type water tank, which can effectively save the amount of flushing water.

The utility model adopts a straight-through type toilet body outlet, does not need to form a siphon when draining water, and can also save flushing water.

The utility model is equipped with a discharge valve on the outlet pipeline of the toilet body, which can isolate the odor and prevent the odor from returning upward; the discharge valve is driven by a hydraulic cylinder, and the hydraulic cylinder uses flushing water as the working medium

The utility model has beneficial effects: the bedpan is flushed with the pressure water in the pressure storage type water tank, and the straight-through toilet outlet is used instead of the siphon drainage, which greatly saves the amount of flushing water.

A discharge valve is installed on the toilet discharge outlet pipeline, which can isolate the odor and prevent the odor from returning upwards; the discharge valve is driven by a hydraulic cylinder, and the hydraulic cylinder uses flushing water as the working medium, which does not need to be connected and consumes additional energy.

Detailed ways

As shown in Figure 1, a water-saving toilet includes a toilet body 1, the toilet body 1 is connected with a pressure storage type water tank 4 through a flush valve 6, and the outlet of the lower part of the toilet body 1 is provided with a sliding gate type discharge valve 2, The discharge valve 2 is connected with the hydraulic cylinder 3 which drives it to move, and the hydraulic cylinder 3 is provided with an interface at its upper end and the end connected with the discharge valve 2 to communicate with the interface of the flush valve 6 respectively.

The water source is connected to the pressure storage water tank 4 through the one-way valve 5, and the flush valve 6 is a manual two-position three-way valve. The interface II of the flush valve 6 is connected to the pressure storage water tank 4, and the interface I is connected to the interface of the hydraulic cylinder 3 A, the interface III and the interface B of the hydraulic cylinder 3 are connected to the flushing interface of the toilet body 1 .

As shown in Figure 1, a pre-inflated air bag 7 is included in the pressure storage type water tank. When the water from the source water enters the pressure storage type water tank through the one-way valve, the pressure of the source water will compress the air bag. The purpose of setting the one-way valve is to Keep the pressure in the pressure storage tank. When the water source pressure is greater than the water pressure in the storage tank, the water source can continue to replenish water in the storage tank. When the water source pressure fluctuates and is lower than the water pressure in the storage tank , the pressure storage type water tank can maintain the water pressure to ensure that the water pressure in it is at the maximum value of the water source pressure within a period of time.

As shown in Figure 2, the flush valve is a manual 2-position 3-way valve. In the standby state, port I of the valve communicates with port III. When the manual button of the valve is pressed, port I of the valve communicates with port II. By adding a delay mechanism to the valve, the opening time of the valve can be controlled.

As shown in Figure 1, the discharge valve 2 is a sliding gate valve, which can be opened or closed under the drive of a hydraulic cylinder.

As shown in Figure 1, hydraulic cylinder 3 is a special hydraulic cylinder. When the pressure water working medium enters the hydraulic cylinder from port A, the working medium pushes the piston to move to the right until the piston moves completely to the right of port B. At this time, Port B is connected to port A, and the pressure water enters the flush port of the toilet body through port B to flush the toilet bowl; after flushing, the piston of the hydraulic cylinder returns to its position under the force of the spring, and the water on the left side of the hydraulic cylinder flows into the toilet seat through the flush valve. In the bedpan.

The working process of the present utility model is as follows:

The water from the water source enters the pressure storage water tank through the one-way valve, the air bag is compressed → press the flush button → the interface II of the flush valve communicates with the interface I, the air bag in the pressure storage water tank starts to expand, presses the water out, and passes through The flushing valve enters the left chamber of the hydraulic cylinder → the piston of the hydraulic cylinder moves to the right under the action of the pressure water → when the piston of the hydraulic cylinder moves completely to the right of the port B, the port A is connected to the port B, and the discharge valve has been closed at this time Open, the pressure water flows into the flushing port of the toilet body from the port B, and flushes the bedpan → after a period of time, the flushing button resets → the port II of the flush valve is disconnected from the port I, and the port I is connected to the port III → the piston of the hydraulic cylinder Move to the left under the force of the return spring, the water in the left chamber is discharged from the interface A, and enters the flushing interface of the toilet through the flushing valve → the discharge valve is closed, the water in the left chamber of the hydraulic cylinder continues to enter the bedpan, and forms a little water seal until The piston returns.

During the whole working process, as long as the pressure of the water in the pressure storage type water tank is lower than the water pressure of the water source, the water from the water source will replenish the water for the pressure storage type water tank at any time.
