Incremental water replenishing device and method

Abstract

The invention discloses an incremental water replenishing device. The device comprises a water inlet valve, an incremental mechanism, a water replenishing passage and a switching valve; the water inlet valve is used for storing water for a water tank, and the water tank has a third water stop water level controlled by the water inlet valve; the incremental mechanism is used for raising the water storage water level of the water tank, and the water level of the water tank is raised to a first water stop water level from the third water stop water level; after water in the water tank passes through the water replenishing passage and flows to a toilet bowl water seal for water replenishing, the water level of the water tank is lowered to a second water stop water level from the first water stop water level; when the water level of the water tank is located on the first water stop water level, the switching valve opens the water replenishing passage, and when the water level of the water tank is located on the first water stop water level or the second water stop water level, the switching valve stops water inflow; in this way, equivalent control can be conducted on the water replenishing amount of complete discharge and half discharge of a drain valve, so that the water replenishing amount for the toilet bowl water seal is not affected by complete discharge and half discharge of the drain valve, and the compatibility of the device is better. The invention further provides an incremental water replenishing method.

Description

technical field [0001] The invention relates to an incremental water supply device and a water supply method. Background technique [0002] Siphon toilets generally need to replenish water after draining, so that the water seal reaches the required water level, and prevent the gas in the sewage pipe system from entering the room and polluting the indoor air. [0003] The water replenishment method of the prior art usually adopts that after the toilet is drained, a part of the water is branched during the water intake process of the water inlet valve to replenish the toilet through the overflow pipe of the drain valve. The water replenishment method generally has the following defects: [0004] 1. After the flushing of the water tank, the water inlet valve will start to enter the water and replenish the water. When the initial part of the replenishment reaches the toilet, it will be siphoned away along with the flushing water, and cannot stay in the toilet to play a water sea...

AI Technical Summary

Problems solved by technology

[0004] 1. After the flushing of the water tank, the water inlet valve will start to enter the water and replenish the water. When the beginning part of the replenishment reaches the toilet, it will be siphoned away along with the flushing water, and it cannot stay in the toilet to play a water seal function, resulting in a waste of water resources;

[0005] 2. The water replenishment time of the water inlet valve in the prior art is the same as the water inlet time of the water inlet valve, and the water replenishment amount is affected by the water replenishment time and the water replenishment flow rate, resulting in an unstable amount of water replenishment, and it is difficult to accurately control the amount of water replenishment, thereby Too little water supply may affect the siphon effect of the toilet, or excessive water supply may cause waste of water resources;

[0006] 3. Because the replenishment time when the drain valve is fully drained is longer than that when the drain valve is half drained, the water replenishment amount when the drain valve is fully drained is greater than that when the drain valve is half drained. When the amount of replenishing water in the row is sufficient, the amount of replenishing water in the whole row will be too much, which will also cause waste of water resources
