Water supply device and water supply method for double-flush toilet

Abstract

The invention discloses a water supplementing device for a double-flushing closestool and a water supplementing method. The water supplementing device comprises a water supplementing body and a buoy, wherein the water supplementing body is internally provided with a water-supplementing control cavity and is provided with a water inlet and a water outlet communicated with the water-supplementing control cavity; and the buoy is arranged in the water-supplementing control cavity in a manner of up-down movement. The water supplementing device and the water supplementing method disclosed by the invention have the advantages that the buoy is arranged in the water supplementing body, and responses a large-flushing switch and a small-flushing switch to make the periods of time for stopping water discharge of the water outlet different or make the water outlet have the flowing speeds corresponding to the different periods of time, so that first water supplementing amount and second water supplementing amount are realized; the structure is novel, the concept is ingenious, the water supplementation is reliable and the matching performance is strong. In addition, the invention also provides the water supplementing method for the double-flushing closestool.

Description

technical field [0001] The invention relates to a water supply system for a toilet, in particular to a water supply device and a water supply method for a double-flush toilet. Background technique [0002] Existing toilets generally replenish water to the water seal at the bottom of the toilet bowl after flushing to ensure sufficient water seal water volume to avoid indoor air pollution from the odor of the sewage channel. In the prior art, the water replenishment channel is generally set. Size (that is, the cross-sectional area of ​​the replenishment channel) to control the amount of water replenishment, that is, when the cross-sectional area of ​​the replenishment water channel is larger, the amount of water replenishment is also larger, and vice versa; on the other hand, when the toilet in the prior art uses When the drain valve of the double flushing structure is used to realize double flushing of large and small sizes, the water replenishment volume of small flushing an...

Problems solved by technology

[0002] Existing toilets generally replenish water to the water seal at the bottom of the toilet bowl after flushing to ensure sufficient water seal water volume to avoid indoor air pollution from the odor of the sewage channel. In the prior art, the water replenishment channel is generally set. Size (that is, the cross-sectional area of ​​the replenishment channel) to control the amount of water replenishment, that is, when the cross-sectional area of ​​the replenishment water channel is larger, the amount of water replenishment is also larger, and vice versa; on the other hand, when the toilet in the prior art uses When the drain valve of the double flushing structure is used to realize double flushing of large and small sizes, the water replenishment volume of small flushing and large flushing is usually inconsistent. Generally, the same replenishment channel is used for replenishment of large and small flushes, that is, the water replenishment channels of large and small flushes are of the same size. In this case, the large flushing time is longer and the replenishment amount is larger, and the small flushing time is shorter and the replenishment amount is smaller. Congress causes some hydration to be wasted

In addition, there are also some double-flush toilets that require a large amount of water replenishment for small flushes, but small amounts of water replenishment for large flushes. In this way, the prior art cannot separately control the amount of water replenishment for large and small flushes, so the above-mentioned requirements for double-flush toilets cannot be met.
