Detailed ways

In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings. This statement only states that the terms upper, lower, left, right, front, back, inside, outside, etc. that appear or are about to appear in the text of the present invention are only based on the drawings of the present invention and are not specific to the present invention. limited.

Referring to Figure 2, Figure 2 shows a flow chart of the first embodiment of the toilet flushing noise reduction method of the present invention, which includes:

S101, the injection solenoid valve that drives the injection assembly is energized.

It should be noted that the toilet includes a spray assembly, a liquid level detection module, a scrubbing assembly located in the toilet bowl, and a solenoid valve group connected to the spray assembly and the scrubbing assembly. The control solenoid valve group includes a spray solenoid valve connected to the spray assembly. and a scrubber solenoid valve connected to the scrubber component.

When the control board receives the user's flush signal, the control board drives the injection solenoid valve corresponding to the injection assembly to energize, so that the injection head in the injection assembly begins to spray water into the toilet.

S102, detect the on-off status of the liquid level detection circuit in real time.

After starting the toilet flushing, the real-time water cover in the toilet will continue to decrease. When the real-time water cover in the toilet is not lower than the preset reference liquid level, it means that the toilet does not produce siphon, even if the liquid level in the pool is normal; when When the real-time water cover in the toilet is lower than the preset reference level, it means that the toilet has produced siphon, even if the liquid level in the pool is abnormal.

It should be noted that the detection circuit is used to detect the liquid level status in the toilet; when the liquid level detection circuit is disconnected, it means that the liquid level in the toilet is abnormal. At this time, if the spray head still keeps spraying water, the water will not flow. On the ceramic S-bend pipe that does not store water, a very loud noise will be produced; when the liquid level detection circuit is turned on, it means that the liquid level in the toilet is normal, and even if the spray head continues to spray water, there will be no noise.

Specifically, the detection circuit includes a control board and two conductors respectively connected to the control board. The height of the two conductors is not higher than the preset reference liquid level and the height of at least one of the two conductors is located at Base level, where:

(1) When the liquid level in the toilet is lower than the reference level, it means that the liquid level in the toilet is abnormal and the liquid level detection circuit is open;

(2) When the liquid level in the toilet is higher than or equal to the reference liquid level, it means that the liquid level in the toilet is normal. The two conductors connect the liquid level detection circuit with the conductive liquid in the toilet. .

As shown in Figure 6, when the real-time water cover in the toilet is at the first water cover position H1, both conductors are soaked in water. Under the conductive effect of water, a conductive loop is formed between the two conductors and the control board. To feed back the connection signal to the control board, at this time, the control board can confirm that the toilet does not produce a siphon state according to the connection signal; when the real-time water cover in the toilet is at the second water cover position H2, the two conductors are disconnected, and the two conductors are disconnected. A conductive circuit cannot be formed between the body and the control board. At this time, the control board can confirm that the toilet has produced siphon. Preferably, both conductors are conductive probes, but this is not a limitation and can be selected according to actual conditions.

S103. When the liquid level detection circuit is disconnected, control the opening and closing state of the solenoid valve group to correspondingly control the opening and closing of the injection assembly and/or the washing assembly.

When the liquid level detection circuit is broken, it means that the toilet has produced siphon. At this time, it is necessary to switch the opening and closing state of the solenoid valve group to reduce the noise caused by siphon.

S104, when the liquid level detection circuit is turned on, determine whether the power-on time of the injection solenoid valve reaches the preset time.

When the liquid level detection circuit is turned on, it means that the toilet does not produce siphon. At this time, the flushing process can continue, and the progress of the flushing process can be monitored through the power-on time.

S105, if the energization time reaches the preset time, close the injection solenoid valve; if the energization time does not reach the preset time, return to step S101 to keep the injection solenoid valve energized.

If the power-on time reaches the preset time, it means flushing is completed, and the injection solenoid valve can be closed normally to end the flushing process;

If the power-on time does not reach the preset time, it means that the flushing is not completed, and the injection solenoid valve can be kept powered on to continue the flushing process.

Therefore, the present invention realizes real-time judgment of siphon status through real-time detection of the liquid level detection circuit, and facilitates the control panel to switch the opening and closing status of the solenoid valve group to reduce noise caused by siphon.

Referring to Figure 3, Figure 3 shows a flow chart of a second embodiment of the toilet flushing noise reduction method of the present invention, including:

S201, the injection solenoid valve that drives the injection assembly is energized.

S202, detect the on-off status of the liquid level detection circuit in real time.

S203, when the liquid level detection circuit is disconnected, close the injection solenoid valve.

The liquid level detection circuit is broken, which means that the real-time water surface in the toilet is lower than the reference liquid level. At this time, the injection solenoid valve can be closed so that the spray head will no longer flush water, thereby reducing the noise caused by the spray head continuing to spray.

S204, when the liquid level detection circuit is turned on, determine whether the power-on time of the injection solenoid valve reaches the preset time.

S205, if the energization time reaches the preset time, close the injection solenoid valve; if the energization time does not reach the preset time, return to step S201 to keep the injection solenoid valve energized.

Therefore, in this embodiment, it is clear that the injection solenoid valve can be closed so that the injection head in the injection assembly no longer flushes water, thereby reducing the noise caused by the injection head continuing to spray, which is easy to operate and has a significant noise reduction effect.

Referring to Figure 4, Figure 4 shows a flow chart of a third embodiment of the toilet flushing noise reduction method of the present invention, including:

S301, the injection solenoid valve driving the injection assembly is energized.

S302, detect the on-off status of the liquid level detection circuit in real time.

S303, when the liquid level detection circuit is disconnected, keep the injection solenoid valve energized and drive the scrubbing solenoid valve of the scrubbing assembly to be energized to replenish water to the toilet.

If the liquid level detection circuit is broken, it means that the real-time water surface in the toilet is lower than the reference liquid level. At this time, the scrubber solenoid valve can be started so that the scrubber head in the scrubbing assembly can continuously replenish water in the toilet to increase the real-time water level in the toilet. The cover is used to reduce the noise caused by siphoning. The scrubbing head is located in the toilet 4 and above the spray head.

S304, when the liquid level detection circuit is turned on, determine whether the power-on time of the injection solenoid valve reaches the preset time.

S305, if the energization time reaches the preset time, close the injection solenoid valve; if the energization time does not reach the preset time, return to step S301 to keep the injection solenoid valve energized.

What is different from the second embodiment shown in Figure 3 is that in this embodiment, the injection solenoid valve can be kept energized to continue the flushing operation, and the scrubber head can be continuously replenished to the toilet to improve the water content in the toilet. Real-time water cover, thus achieving effective noise reduction during flushing.

Referring to Figure 5, Figure 5 shows a flow chart of the fourth embodiment of the toilet flushing noise reduction method of the present invention, including:

S401, the injection solenoid valve that drives the injection assembly is energized.

S402, detect the on-off status of the liquid level detection circuit in real time.

S403, when the liquid level detection circuit is disconnected, the injection solenoid valve is turned off and energized, and the scrubbing solenoid valve of the scrubbing component is driven to energize to replenish water to the toilet.

The liquid level detection circuit is broken, which means that the real-time water cover in the toilet is lower than the reference liquid level. At this time, the injection solenoid valve can be closed and the scrubber solenoid valve can be started at the same time, so that the jet head no longer flushes water and the toilet is cleaned through the scrubber head. Continuous hydration to quickly reduce noise caused by siphoning.

S404, when the liquid level detection circuit is turned on, determine whether the power-on time of the injection solenoid valve reaches the preset time.

S405, if the energization time reaches the preset time, close the injection solenoid valve; if the energization time does not reach the preset time, return to step S401 to keep the injection solenoid valve energized.

What is different from the third embodiment shown in Figure 4 is that in this embodiment, under the joint action of the injection solenoid valve and the scrubber head, the toilet can be quickly replenished, thereby quickly reducing the noise.

From the second to fourth embodiments, it can be seen that the present invention can cooperate with different solenoid valves to stop flushing or continue to replenish water, thereby greatly reducing the noise caused by siphoning.

As shown in Figures 6 and 7, the present invention discloses a noise reduction toilet, which includes a toilet body 1, a solenoid valve group, a liquid level detection device 2 and a control panel 3 (see Figure 9). Specifically, the liquid level detection device 2 is installed in the toilet bowl 4 of the toilet body 1 and is located below the reference liquid level of the toilet bowl 4, and the liquid level detection device 2 is connected to the control panel 3 to form a detection circuit. The liquid level detection device 2 is used to detect the liquid level signal in the toilet 4, so that the detection loop can effectively detect the liquid level status in the toilet 4; the control board 3 is connected to the solenoid valve group and is used to control the electromagnetic according to the liquid level status detected by the detection loop. The opening and closing status of the valve group.

Before starting toilet flushing, the real-time water cover in the toilet 4 is at the first water cover position H1. At this time, the liquid level detection device 2 is soaked in water. Under the conductive effect of the water, the detection loop is turned on and the connection signal is fed back to Control board 3, so that the control board 3 confirms that the toilet does not produce a siphon state according to the connection signal, and does not need to switch the opening and closing state of the solenoid valve group; after starting the toilet flushing, the real-time water cover in the toilet 4 continues to decrease, and the toilet The real-time water cover in the pool 4 is at the second water cover position H2. The liquid level detection device 2 is no longer soaked in water. The detection circuit is disconnected and no longer feeds back the connection signal to the control board 3, so that the control board 3 confirms that the toilet has generated siphon. , at this time it is necessary to switch the opening and closing state of the solenoid valve group to reduce the noise caused by siphon.

Therefore, the present invention realizes real-time judgment of the siphon status by installing the liquid level detection device 2 in the toilet 4, and facilitates the control panel 3 to switch the opening and closing status of the solenoid valve group to reduce the noise caused by siphon.

As shown in Figures 8 and 9, the liquid level detection device 2 includes two independent conductors 21. The installation height of the two conductors 21 is not higher than the preset reference liquid level and at least one of the two conductors 21 is The height of an electrical conductor 21 is located at the reference level, where:

(1) When the liquid level in the toilet 4 is lower than the reference liquid level, the liquid level detection circuit is disconnected;

(2) When the liquid level in the toilet 4 is higher than or equal to the reference liquid level, the two conductors 21 conduct the liquid level detection circuit under the connection of the conductive liquid in the toilet 4 .

It should be noted that the two conductors 21 can form a conductive loop with the control board 3 under the connection of the conductive medium to feed back the connection signal to the control board 3 . For example, when the real-time water cover in the toilet 4 is at the first water cover position H1, both conductors 21 are soaked in water. Under the conductive effect of the water, a conductive loop is formed between the two conductors 21 and the control board 3 , to feed back the connection signal to the control board 3; when the real-time water surface in the toilet 4 is lower than any of the conductors 21, the two conductors are disconnected, and no conductive loop can be formed between the two conductors 21 and the control board 3. Preferably, both conductors 21 are conductive probes, but this is not a limitation and can be selected according to actual conditions.

Furthermore, both conductors 21 are provided on the spray head 5 of the toilet body 1 . It should be noted that the spray head 5 is located at the bottom of the toilet 4, and when there is no water in the bottom of the toilet 4, if the spray head 5 continues to spray water into the ceramic S-bend 6 that does not store water, the water will be sprayed. A very loud noise will be generated on the S-bend 6. Therefore, the present invention uses the position of the spray head 5 as the reference liquid level for siphon judgment, and sets two conductors 21 at the spray head 5 of the toilet body 1 to achieve siphoning. targeted judgment.

Correspondingly, in order to achieve more accurate judgment, the two conductors 21 can be disposed above the water outlet of the spray head 5 to better monitor the liquid level of the toilet 4 .

Therefore, the present invention can utilize the conductive characteristics of water to realize the on-off state of the switching loop, accurately determine the siphon state, and feed back signals to the control panel 3 for corresponding control, with fast response speed and strong flexibility.

As shown in Figure 10, the control panel 3 includes a liquid level detection module 31, a valve group control module 32, a time judgment module 33 and a time control module 34. Specifically:

The liquid level detection module 31 is used to detect the on-off status of the liquid level detection circuit in real time. After starting the flushing of the toilet, the real-time water cover in the toilet 4 will continue to decrease. When the real-time water cover in the toilet 4 is not lower than the preset reference liquid level, the liquid level detection circuit is turned on, which means that the toilet does not generate water. Siphon, even if the liquid level in pool 4 is normal; when the real-time water cover in toilet 4 is lower than the preset reference level, the liquid level detection circuit is broken, which means that the toilet has produced siphon, even if the liquid level in pool 4 abnormal.

The valve group control module 32 is used to drive the injection solenoid valve of the injection assembly to be energized when the flush mode is started, and is also used to control the opening and closing status of the solenoid valve group to control the opening and closing state of the solenoid valve group when the liquid level detection module 31 detects that the liquid level detection circuit is broken. To suppress noise, that is to say, the valve group control module 32 can control the opening and closing state of the solenoid valve group according to the on-off state of the liquid level detection circuit detected by the liquid level detection module 31 . It should be noted that when the control panel 3 receives the user's flush signal, the control panel 3 drives the injection solenoid valve of the injection assembly to be energized, so that the injection head 5 in the injection assembly begins to spray water into the toilet 4; when the liquid If the position detection circuit is open, it means that the toilet has produced siphon. At this time, it is necessary to switch the opening and closing state of the solenoid valve group to reduce the noise caused by siphon.

The time judgment module 33 is used to judge whether the energization time of the injection solenoid valve reaches a preset time when the liquid level detection module 31 detects that the liquid level detection circuit is turned on. When the liquid level detection circuit is turned on, it means that the toilet does not produce siphon. At this time, the flushing process can continue, and the progress of the flushing process can be monitored through the power-on time.

The time control module 34 is used to drive the valve group control module 32 to close the injection solenoid valve when the time judgment module 33 determines that the energization time has reached the preset time; when the time judgment module 33 determines that the energization time has not reached the preset time, then drive the valve Group control module 32 keeps the injection solenoid energized. It should be noted that if the power-on time reaches the preset time, it means that the flushing is completed, and the injection solenoid valve can be closed normally to end the flushing process; if the power-on time does not reach the preset time, it means that the flushing is not completed and the spraying can be maintained. The solenoid valve remains energized to continue the flush process.

Therefore, the present invention realizes real-time judgment of the siphon status through real-time detection of the liquid level detection circuit, and facilitates the control board 3 to switch the opening and closing status of the solenoid valve group to reduce the noise caused by siphon.

Correspondingly, the solenoid valve group includes an injection solenoid valve and a scrubber solenoid valve. The jet solenoid valve is used to control the water outlet state of the spray head 5 in the toilet body 1, and the scrubber solenoid valve is used to control the water outlet state of the scrubber head in the toilet body 1.

Further, the valve group control module 32 includes an injection control unit 321 and a washing control unit 322, wherein:

The injection control unit 321 is used to energize the injection solenoid valve of the injection assembly when the flush mode is started, and is also used to close the injection solenoid valve when the liquid level detection module 31 detects that the liquid level detection circuit is broken;

The washing control unit 322 is used to drive the washing solenoid valve of the washing assembly to energize when the liquid level detection module 31 detects that the liquid level detection circuit is broken, so as to replenish water to the toilet 4 .

When the control board 3 only controls the injection solenoid valve, if the control board 3 cannot obtain the connection signal, the injection control unit 321 can close the injection solenoid valve so that the injection head 5 no longer flushes water, thereby reducing the need for the injection head 5 to continue Noise caused by jetting;

When the control board 3 only controls the washing solenoid valve, if the control board 3 cannot obtain the connection signal, the washing control unit 322 can start the washing solenoid valve, so that the washing head can continuously replenish water for the toilet 4 to improve the toilet 4 Real-time water cover inside, thereby reducing noise caused by siphoning.

When the control board 3 controls the injection solenoid valve and the washing solenoid valve at the same time, if the control board 3 cannot obtain the connection signal, the injection solenoid valve can be closed through the injection control unit 321 and the washing solenoid valve can be started through the washing control unit 322 at the same time, so that the The spray head 5 no longer flushes water and the scrubber head continuously replenishes water to the toilet 4, thereby quickly reducing the noise caused by siphoning.

Therefore, the present invention can be used with different solenoid valves to stop flushing or continue replenishing water, thereby greatly reducing the noise caused by siphoning.

The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also regarded as It is the protection scope of the present invention.
