Problems solved by technology

[0002] At present, the water diversion valves on the market can only realize the function of switching water channels, and do not have the ability to drain the residual water in the pipeline connected to the rear end of the water diversion valve.
For example, for a flushable toilet cover, after flushing, there will generally be residual water in the flushing pipe behind the diverter valve. If there is water residue in the pipe for a long time, it is easy to breed bacteria. Only when it is drained will the warm water flow out, the residual cold water will touch the human body first and cause discomfort, especially in winter, it is more unacceptable, and the residual water is easy to breed bacteria in the pipeline, so it is also very harmful to health, so the existing In the technology, the method to solve this problem is generally at the beginning of flushing, when the nozzle pipe of the toilet cover is not stretched out, this part of the residual water is drained first, and then the warm water flowing out is used for flushing, although this solves the problem of flushing at the beginning of flushing. There will be no cold water in contact with the human body, but such a flushing control program is more complicated, and there will still be residual water in the tube when not in use, which is still easy to breed bacteria, which is not conducive to human health

no. 1 example

[0062] The first embodiment (the water diversion valve includes a water passage and a water discharge passage)

[0063] Such as Figure 1 to Figure 12 As shown, a water diversion valve with a water discharge function in this embodiment includes a water passage and a water discharge channel. When the water diversion valve is opened, the water passage is opened and the water discharge channel is closed, and the water flows through The water passage of the water diversion valve flows into the outlet pipe connected to the rear end of the water diversion valve; The residual water in the pipeline is discharged through the drain channel.

[0064] In this embodiment, the water diversion valve includes a valve body 100 and a valve core. The valve body 100 is provided with a water inlet 110, a water outlet, and a water discharge port 140. The first valve plate 200 and the second valve plate 300 arranged in the inner cavity of the valve body 100, wherein the first valve plate 200 is pr...

[0069] The second embodiment (the water diversion valve includes a water passage, a backflow passage, and a water discharge passage)

[0070] Such as Figure 13 to Figure 24 As shown, in this embodiment, the main difference from the water diversion valve of the above-mentioned first embodiment is that: it also includes a backflow channel, which includes a backflow water outlet 150, a backflow water inlet 160, The return pipe 700 is externally connected to the valve body 100 and communicated with the return outlet 150 and the return inlet 160 , and a return outlet hole in communication with the return outlet 150 is provided on the first valve plate 200 240, the backflow water inlet 250 communicated with the backflow water inlet 160, and the second valve plate 300 is provided with a backflow groove 350 communicated with the backflow water inlet 250, and the backflow groove 350 is connected with The drainage groove 322 and the outlet groove are connected to each other.

Abstract

The invention discloses a shunt valve with a water release function and a closestool cover plate provided with the shunt valve. The shunt valve comprises a water passing channel and a water release channel. When flushing is started, the water passing channel is opened and the water release channel is closed. After the flushing is completed, the water passing channel is closed and the water release channel is opened, and residual water in a pipeline connected with a downstream part of the shunt valve is released through the water release channel, so that bacteria breeding due to long-time accumulated water is avoided; in addition, the problem that the cooler residual water touches a human body first and leads to discomfort when the water passes a closestool using the shunt valve every time can be solved; and the closestool is healthier and more comfortable.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a water diversion valve with a drain function and a toilet cover with the water diversion valve. Background technique [0002] At present, the water diversion valves on the market can generally only realize the function of switching water channels, and do not have the ability to drain the residual water in the pipeline connected to the rear end of the water diversion valve. For example, for a flushable toilet cover, when the flushing is over, there will generally be residual water in the flushing pipe behind the diverter valve. If there is water residue in the pipe for a long time, it is easy to breed bacteria. Only when it is drained will the warm water flow out, the residual cold water will touch the human body first and cause discomfort, especially in winter, it is more unacceptable, and the residual water is easy to breed bacteria in the pipeline, so it is also very har...
