Description

water saving toilet tank

technical field

The utility model belongs to the field of sanitary ware, in particular to a water-saving toilet water tank.

Background technique

There is a lot of waste water in life that can be used to flush toilets, the purpose of which is to save water for cleaning. But most of the existing flush toilets do not possess the function of utilizing waste water. Although some toilet water tanks are connected with waste water tanks or water pipes so that waste water can directly flow into the toilet water tanks, the effect of saving cleaning water has not been reached in essence. The reason is that the connected clean water (tap water) will quickly fill the water tank and reach the set water level after the existing toilet water tank has drained the water each time, and the waste water of China Unicom often flows into the toilet water tank after this. The inflow of waste water just increases the water volume in the toilet tank, which will be drained at once along with the cleaning water in the next discharge. In this way, it appears that the waste water has been utilized, but the cleaning water has not been saved.

Contents of the invention

The purpose of the utility model is to propose a water-saving toilet tank capable of fully utilizing waste water to flush the toilet.

The technical solution for achieving the above purpose is: a water-saving toilet water tank, including a water tank body, an automatic tap water inlet valve and a drain valve. The automatic water inlet valve and the drain valve are set in the lower water tank; the upper water tank is connected to the waste water pipe, and there is a waste water automatic drain valve at the bottom, and the waste water automatic drain valve is controlled by a floating ball linkage mechanism located in the lower water tank, and the waste water is automatically drained. The drainage flow rate of the drain valve is 3-4 times of the water inlet flow rate of the tap water automatic water inlet valve.

An overflow port is arranged on the side wall of the upper water tank, and the overflow port communicates with the external floor drain through an overflow pipe.

The drain valve is provided with a drain button, and the drain button is arranged at the middle upper part of the side wall of the water tank body.

After being full of water in each lower floor water tank, the waste water automatic drain valve and tap water automatic water inlet valve at the bottom of the upper floor water tank can be closed simultaneously under the control of the respective float linkages. Afterwards, the upper water tank can accumulate waste water. When the toilet is flushed to release the water stored in the lower water tank, the waste water automatic drain valve and the tap water automatic water inlet valve at the bottom of the upper water tank will be opened simultaneously under the control of their respective floating ball linkage mechanisms. When, the waste water accumulated in the upper water tank will be quickly injected into the lower water tank. Since the drainage flow rate of the waste water automatic drain valve is greater than the water intake flow rate of the tap water automatic water inlet valve, if the injected waste water does not reach the set water level line of the lower water tank, the opened tap water automatic water inlet valve will continue to supplement the tap water. After the water in the lower floor water tank reached the set water level line, the waste water automatic drain valve and the tap water automatic water inlet valve at the bottom of the upper floor water tank can be closed simultaneously under the control of the respective floating ball linkage mechanism again. Repeatedly, automatic control.

The utility model only increases the volume of the water tank body and makes it a double-layer structure, and there are not many added parts, so that the waste water can be fully utilized and the effect of saving cleaning water is achieved. The structure is simple and the practical value is high .

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model comprises a water tank body 1, a tap water automatic water inlet valve 5 and a drain valve 7, the water tank body 1 is a double-layer structure up and down, divided into two water storage areas up and down, and a water tank cover 11 is arranged at the upper end. Lower floor water tank 2 is identical with the main structure of existing flush toilet water tank, and tap water automatic water inlet valve 5 is installed on the side wall of lower floor water tank 2. The drain valve 7 is opened under the control of the drain button 6. The drain button 6 is arranged on the middle and upper part of the side wall of the water tank body 1. The drain button 6 is connected with the drain valve 7 at the bottom of the lower water tank 2. The tap water automatic inlet valve 5 consists of a Float linkage control. The upper water tank 3 is connected to the waste water pipe 8 for accumulating domestic waste water, and its side wall is provided with an overflow port, which communicates with the external floor drain through the overflow pipe 10 . A waste water automatic drain valve 9 is installed on the bottom of the upper water tank 3, and the waste water automatic drain valve 9 is also controlled by a ball float linkage mechanism. The float 501 of the water valve 5 switch is at the same horizontal position. The drainage flow velocity of waste water automatic drain valve 9 is 3-4 times of the water inlet flow velocity of tap water automatic water inlet valve 5.

As shown in Figure 2, the water tank body 1 may not need the upper water tank cover 11, and is directly installed under the basin 12, and the drain pipe 701 positioned at the bottom of the water tank body 1 is connected to the toilet. The waste water pipe 8 at the bottom of the washbasin 12 is directly connected to the upper water tank 3, so that washing hands, face or other domestic waste water can directly flow into the upper water tank 3 at ordinary times.
