Abstract
Description
Technical Field
[0001] The invention belongs to the field of sanitary ware, and more specifically, is a method for improving the flushing effect of a water tankless flush toilet. Background Art
[0002] The working principle of the tankless flush toilet currently on the market is to fully utilize the tap water pressure, use a tee to divide the water inlet pipe into an upper flush pipe and a lower flush pipe, and respectively provide a normally closed solenoid valve A and a normally closed solenoid valve B on the upper flush pipe and the lower flush pipe, and the opening and closing of the solenoid valve A and the solenoid valve B are controlled by the circuit board program; when flushing the toilet, the program first opens the solenoid valve A of the upper flush pipe for 3 seconds to flush the scattered dirt on the surface of the toilet tank into the sinking pond, and after closing for 1 second, the normally closed solenoid valve B of the lower flush pipe is opened for 4 seconds to flush the dirt in the sinking pond into the sewer, and after closing for 1 second, the normally closed solenoid valve A of the upper flush pipe is opened again for 3 seconds, and the water flow is used to clean the toilet tank and close the sinking pond; this working principle is an existing mature technology and does not need to be repeated here; with the promotion and popularization of the tankless flush toilet that uses tap water pressure to flush the toilet on the market, higher requirements are also put forward for the flushing effect.
[0003] Its technical defects are:
[0004] The working principle of the tankless flush toilet that uses tap water pressure to flush the toilet is an existing mature technology and there is no need to repeat it here. Due to the small diameter of the tap water pipe, the water storage capacity at the water inlet pipe end of the toilet is small, and the distance from the water pipe to the user's home is long. When flushing the toilet, the water pressure drops rapidly, the dynamic water pressure at the water outlet is very small, and the flushing volume is also small. Especially for users in high-rise buildings or during peak water usage periods, this flushing method of the tankless flush toilet cannot flush the dirt in the toilet clean. Summary of the invention:
[0005] With the promotion and popularization of tankless flush toilets on the market, in order to improve the flushing effect of tankless flush toilets and meet more market demands.
[0006] The technical solution adopted by the present invention is:
[0007] The method for improving the flushing effect of a tankless flush toilet comprises an upper toilet seat, a lower toilet seat, a toilet liner, an upper flushing water pipe, a lower flushing water pipe, and two solenoid valves and a circuit board for controlling the upper and lower flushing water pipes. The special feature of the method is that a closed container is added to the water inlet pipe of the tankless flush toilet.
[0008] The present invention is implemented as follows:
[0009] The method for improving the flushing effect of a tankless flush toilet comprises an upper toilet seat, a lower toilet seat, a toilet liner, a sink, an upper flushing pipe, a lower flushing pipe, and two normally closed solenoid valves and a program control circuit board on the upper and lower flushing pipes of the existing tankless flush toilet on the market. Since the diameter of the tap water pipe is small, the water storage capacity of the toilet water inlet pipe near the solenoid valve end is limited, and the distance from the tap water pipe to the user's home is long. When flushing the toilet, the solenoid valve opens the moment of flushing the toilet, and the water flow is rapidly ejected from the toilet water outlet. When the water inlet pipe is in a flowing state, its dynamic water pressure is rapidly reduced, so that the flushing water volume and water pressure of the toilet water outlet are small. The present invention is a method for improving the flushing effect of a tankless flush toilet. A closed container is added to the water inlet pipe with a tee, the purpose of which is to increase the water storage capacity of the toilet water inlet pipe near the solenoid valve end. The increased water volume is proportional to the volume in the closed container. When the solenoid valve is closed, the closed container is connected to the water inlet pipe, and the water pressure in the closed container is consistent with the water pressure in the water inlet pipe. When the solenoid valve is opened to flush the toilet, under the static water pressure of the water inlet pipe, the water flow in the closed container flows into the toilet water outlet together with the water flow in the water inlet pipe, thereby reducing the water flow from the water inlet pipe. While reducing the water flow in the water inlet pipe, the speed at which the water pressure in the water inlet pipe decreases is also slowed down, thereby increasing the flow and water pressure at the toilet outlet.
[0010] The method for improving the flushing effect of a tankless flush toilet, wherein the sealed container can be installed outside the tankless flush toilet or inside the tankless flush toilet.
[0011] The method for improving the flushing effect of a tankless flush toilet has a closed container whose opening can be in any direction, and the water in the closed container is always connected to the water in the water inlet pipe.
[0012] The beneficial effects of the present invention are as follows:
[0013] Since the present invention increases the flow rate of the toilet water outlet and slows down the speed at which the flowing water pressure in the water inlet pipe decreases, the water pressure and flow rate of the toilet water outlet are improved, the water flow at the water outlet of the tankless flush toilet is stronger, and the flushing effect of the tankless flush toilet is effectively improved.

[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] Depend on Figure 1 As shown;
[0022] The working principle of the tankless flush toilet on the market is an existing mature technology. It includes the original tankless flush toilet upper seat 1, toilet lower seat 2, toilet liner 3, sink 7, upper flush pipe 5, lower flush pipe 16, and normally closed solenoid valve A17, normally closed solenoid valve B15, control circuit board 10. When flushing the toilet, the normally closed solenoid valve A17 is first opened for 3 seconds, and the water flows through the upper flush pipe 5, and the horizontal flushing water 4 sprayed from the upper water outlet 19 flushes the scattered dirt on the surface of the toilet liner 3 into the sink 7, and then closes 1. After seconds, the normally closed solenoid valve B15 is opened for 4 seconds, and water flows through the lower flush pipe 16 and is sprayed out from the lower water outlet 20 of the toilet to flush the dirt in the sump 7 into the sewer. After being closed for 1 second, the normally closed solenoid valve A17 is opened for 3 seconds again, and water flows from the upper water outlet 19 to flush the surface of the toilet liner 3 and the closed sump 7 in the horizontal direction. However, due to the small diameter of the tap water pipe, the water storage capacity of the toilet water inlet pipe 13 near the solenoid valve end is small, and the distance from the water pipe to the user's home is long. When flushing the toilet, the water pressure drops rapidly and the flushing volume is also small.
[0023] Depend on Figure 2 As shown;
[0024] It is a schematic diagram of the structure of the present invention with the opening at the top, the end 18 of the tube 9 is located below the horizontal plane in the closed container 8, is in water communication with the water inlet pipe 13, and the opening is sealed with a sealing screw 11.
[0025] Depend on Figure 3 As shown;
[0026] It is a schematic diagram of the structure of the present invention with the opening at the bottom, the end 18 of the tube 9 is located below the horizontal plane in the closed container 8, is in water communication with the water inlet pipe 13, and the opening is sealed with a sealing screw 11.
[0027] Figure 4 As shown;
[0028] A sealed container 8 with an opening at the top is placed outside the tankless flush toilet and connected to the water inlet pipe 13 with a tee 14. The purpose is to increase the amount of stored water at the end of the water inlet pipe 13 close to the solenoid valve. The increased amount of water is proportional to the volume in the sealed container 8. The normally closed solenoid valve B15 and the normally closed solenoid valve A17 are both in a closed state, the sealed container 8 is connected to the water inlet pipe 13, and the water pressure in the sealed container 8 and the water inlet pipe 13 is consistent, and both are in a static water pressure state.
[0029] Depend on Figure 5 As shown;
[0030] A sealed container 8 with an opening at the top is placed outside the tankless flush toilet and connected to the water inlet pipe 13 with a tee 14. The purpose is to increase the amount of water stored in the water inlet pipe 13 near the solenoid valve end. When the normally closed solenoid valve B15 is opened, under the static water pressure in the water inlet pipe 13, the water in the sealed container 8 and the water in the water inlet pipe 13 flows through the lower flush pipe 16 and is sprayed out from the lower water outlet 20 of the toilet. Since the water in the sealed container 8 and the water in the water inlet pipe 13 flows into the lower water outlet 20 of the toilet at the same time, the water flow in the water inlet pipe 13 is reduced, and the speed at which the water pressure in the water inlet pipe 13 decreases is also slowed down, so that the water pressure and water flow sprayed out from the lower water outlet 20 of the toilet are greater.
[0031] Example
[0032] Depend on Figure 4As shown, the normally closed solenoid valve B15 and the normally closed solenoid valve A17 are both in the closed state, the sealed container 8 is connected to the water inlet pipe 13, the water pressure in the sealed container 8 and the water inlet pipe 13 is consistent, and is in a static water pressure state. When flushing the toilet, the program opens the normally closed solenoid valve A17 for a moment, and the water flow in the sealed container 8 and the water inlet pipe 13 is sprayed out in the horizontal direction of the flushing 4 through the upper flushing pipe 5 from the upper water outlet 19 of the toilet under the static water pressure, and the dirt on the surface of the toilet liner 3 is washed to the sink 7. Due to the water flow in the sealed container 8 At the same time as the water flow in the water inlet pipe 13, it flows into the water outlet 19 on the toilet, reducing the flow from the water inlet pipe 13, thereby slowing down the speed of water pressure reduction in the water inlet pipe 13 and increasing the flow and water pressure of water sprayed out of the water outlet 19 on the toilet; 3 seconds later, when the normally closed solenoid valve B15 is closed for 1 second, since the closed container 8 is connected to the water inlet pipe 13, the water in the closed container 8 is replenished, and its water pressure quickly returns to the static water pressure, and then the water replenishment is stopped; the water pressure in the closed container 8 and the water inlet pipe 13 is in the static state again. Water pressure state; the program opens the normally closed electromagnetic valve B15 again for a moment, at this time the closed container 8 and the water inlet pipe 13 are connected with the lower water outlet 20, the water flow in the closed container 8 and the water inlet pipe 13, under the static water pressure, passes through the lower flushing pipe 16, and is sprayed out from the lower water outlet 20 of the toilet, flushing the dirt in the sink 7 into the sewer, similarly, since the water flow in the closed container 8 and the water inlet pipe 13 simultaneously flows into the lower water outlet 20 of the toilet, the water flow from the water inlet pipe 13 is reduced, and the speed of the water pressure reduction in the water inlet pipe 13 is also slowed down. degree, so that the water pressure and water flow sprayed out of the water outlet 20 under the toilet are greater; 4 seconds later, when the normally closed solenoid valve B15 is closed for 1 second, the closed container 8 is connected with the water inlet pipe 13, and the closed container 8 is replenished with water again. When the water pressure quickly returns to the initial static water pressure, the water replenishment stops; at this time, the water pressure in the closed container 8 and the water inlet pipe 13 is in a static water pressure state, and when the program opens the normally closed solenoid valve A17 again, the toilet liner 3 and the closed sink 7 are cleaned, and its working process is the same as the working process when the normally closed solenoid valve A17 is opened above.
