Flushing system of closestool and closestool
The invention discloses a flushing system of a closestool. The flushing system comprises a pump, a reversing valve 10 and a control unit. The time for the pump to provide the flushing flow is divided into first, second and third time periods. In the second time period, the control unit outputs a control signal. A reversing cavity (122), a water inlet pipeline (124), an upper flushing pipeline (126) and a lower flushing pipeline (128) are formed in the reversing valve, and the water inlet pipeline (124), the upper flushing pipeline (126) and the lower flushing pipeline (128) are communicated with the reversing cavity. A reversing rotor (14) is arranged in the reversing cavity, and the reversing rotor is controlled to be switched from the normally-closed position to the undershoot position after a control signal is obtained. Water flow is introduced into the upper flushing pipeline at the normally-closed position and is introduced into the lower flushing pipeline at the lower flushing position. An exhaust channel (129) communicated with the upper flushing pipeline and the lower flushing pipeline is formed in the reversing valve, and air in the lower flushing pipeline can be exhausted into the upper flushing pipeline through the exhaust channel under the negative pressure effect caused by water flow of the upper flushing pipeline when the reversing valve is in the normally-closed position. By means of the structure, flushing noise can be reduced. The invention further provides the closestool.
本申请公开了马桶的冲水系统，包括泵、换向阀10、控制单元。泵提供冲水水流的时间分为第一、第二和第三时间段。处于第二时间段时控制单元输出控制信号。换向阀形成换向腔(122)及分别与换向腔联通的进水管路(124)、上冲管路(126)和下冲管路(128)。换向腔内具有换向转子(14)，在获取控制信号后控制换向转子从常闭位置切换至下冲位置。位于常闭位置将水流引入上冲管路，位于下冲位置将水流引入下冲管路。换向阀内形成联通上冲管路和下冲管路的排气通道(129)，在常闭位置时下冲管路的空气会因上冲管路水流引起的负压作用通过排气通道排入上冲管路。上述结构可减少冲水噪音，还提供了一种马桶。
