Detailed Description
The following further describes the embodiments of the present invention, but the embodiments of the present invention are not limited thereto.
Referring to fig. 1-6, a toilet includes a toilet body 1 and a toilet flushing system 2 with a tank.
The toilet flushing system 2 with a water tank comprises: a water tank 21, a pressure pump 22, a water inlet pipeline 23 and a flushing pipeline 24; the water inlet pipeline 23 is connected with the water inlet 211 of the water tank 21, and a section of open-type air suction port 212 is arranged at the joint of the water inlet pipeline 23 and the water inlet 211; the suction port 212 is used for sucking some air to destroy the vacuum of the water inlet 211 when the water inlet pipeline 23 is filled with water to generate negative pressure, so that the water in the water tank 21 is prevented from flowing back, and the sewage in the water tank can be better prevented from flowing back and being polluted to a water inlet source. The outlet of the tank 21 is connected to a flushing line 24 by means of a pressure pump 22. Thus, the toilet flushing system 2 with the water tank is formed, water is added into the water tank 21 through the water inlet pipeline 23, then the water is pumped into the water tank 21 through the pressure pump 22, and then the flushing is realized through the flushing pipeline 24.
The toilet flushing system 2 with cistern needs to perform two functions: 1) when the water in the water tank 21 is insufficient, water is automatically added to the water tank through the water inlet pipeline 23. 2) When the water tank 21 is not sufficiently filled with water, the pressure pump 22 does not draw water from the water tank 21. Therefore, the situation that the water is flushed under the condition that the water level in the water tank 21 is insufficient and then the flushing force is insufficient, so that the dirt cannot be thoroughly cleaned is avoided.
In order to have the two functions, a liquid level sensor is arranged in the water tank 21, and a water inlet electromagnetic valve 231 in the water inlet pipeline 23 is opened or closed according to the liquid level in the water tank 21; when the toilet is flushed, the pressure pump 22 sucks or does not suck water from the water tank 21 according to the level of the liquid in the water tank 21.
The liquid level sensor can adopt a single liquid level sensor, and can also adopt a plurality of liquid level sensors to be combined for use. In this embodiment, the liquid level sensors include a water inlet level sensor 213 and a flush level sensor 214; the water inlet liquid level sensor 213 is provided with a water inlet electromagnetic valve opening liquid level and a water inlet electromagnetic valve closing liquid level; the flushing liquid level sensor is provided with a pressure pump starting liquid level. When the liquid level in the water tank is lower than the opening level of the water inlet electromagnetic valve, the water inlet electromagnetic valve 231 is opened, and the water inlet pipeline 23 adds water to the water tank 21. When the liquid level in the water tank is higher than the closing liquid level of the water inlet electromagnetic valve, the water inlet electromagnetic valve 231 is closed, and the water inlet pipeline 23 stops adding water to the water tank 21. The pressure pump 22 can draw water from the tank 21 when the level of the water in the tank 21 is above the pressure pump on level.
In this embodiment, in order to realize the connection between the water tank 21 and the water inlet pipeline 23, the upper end of the water tank 21 is connected to a drainage tube 215, and the upper end of the drainage tube 215 is a water inlet 211 connected to the water inlet pipeline 23; the draft tube 215 is further provided with an overflow tube 216 below the suction port 212, and the other end of the overflow tube 216 is connected to the toilet body 1. The purpose of the overflow pipe 216 is that, when the water inlet level sensor 213 fails, the water inlet solenoid valve 231 is always in an open state, and the water in the water tank 21 is filled, so that after the overflow pipe 216 is arranged, the excess water can flow from the overflow pipe 216 to the toilet body 1, and the overflow of the water is avoided.
In this embodiment, the distance between the air suction port 212 and the overflow pipe 216 is greater than 20mm and less than 100 mm; the lower edge of the inner pipe of the overflow pipe 216 is 0-50mm higher than the overflow surface of the ceramic basin surface. The cross-sectional shape of the overflow pipe is circular or rectangular.
The inner diameter of the drainage tube 215 is set between 30 mm and 80mm, the drainage tube can be in the shape of a circle, a polygon rectangle or an irregular shape, and the value range of the cross section area is 700mm2～5000mm2To (c) to (d); the section range is taken in the interval and matched with the flow limiting valve 233 which is connected in series on the water inlet pipeline 23, so that the water inlet flow of the water tank can be limited to 3-10L/min, the flow can meet the requirement that the water tank is filled with water in a short time, and the noise generated when water is added can be limited in a reasonable range.
The drainage tube 215 is provided with a water inlet assembly 232 above the suction port 212; the steady flow device composed of at least two meshes 2321 is arranged in the water inlet assembly 232, so that water can be prevented from splashing, and the number of the meshes is at least more than 2. The upper end surface of the drainage tube 215 extends upwards to form a mounting column 217, and the water inlet assembly 232 is fixedly connected with the end surface of the mounting column 217 through a screw. In this embodiment, three mounting posts 217 are spaced along the upper end surface of the draft tube 215, and the space between the mounting posts 217 forms the open suction port 212.
In this embodiment, the flushing line 24 includes a main flushing line 241 and a loop flushing line 242; the main flushing pipeline 241 and the circular flushing pipeline 242 are respectively connected with flushing solenoid valves 2411 and 2421 and check valves 2412 and 2422 in series. When flushing, the flushing solenoid valves 2411 and 2421 on the main flushing pipeline 241 and the flushing loop pipeline 242 are respectively opened, and the check valves 2412 and 2422 are used for preventing sewage in the toilet flushing tank from flowing back. The flushing solenoid valves 2411, 2421 are opened for different times according to different flushing programs, such as full flushing and half flushing. The flushing solenoid valve 2411 in the main flushing line 241 is closed before the flushing solenoid valve 2412 in the flushing line 242, and after the main flushing is completed, the flushing is maintained for a certain period of time.
In this embodiment, the toilet further has a flushing function, and can flush people after defecating, so the toilet flushing system 2 with a water tank further comprises a flushing pipeline 25, the flushing pipeline 25 is connected with the water inlet pipeline 23 through a three-way valve 251, the three-way valve 251 is connected in series on the water inlet pipeline 23, and the flushing pipeline 25 is connected with another connector of the three-way valve. A filter 252 is connected in series with the irrigation line 25 to filter the irrigation water to ensure that the skin-contacting water is clean.
The foregoing is merely a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby. Equivalent changes and modifications made according to the patent scope and the specification of the present invention should be covered by the present invention.
