[0027] As Figure 1 shown in example 1:

[0028] The utility model provides a kind of water path system, including working inner container 1, water tank 2, external water source connecting pipeline 3, flow detection pipeline 4;The external water source connecting pipeline 3 is provided with A electromagnetic switch valve 5 for on-off external water source;Downstream of A electromagnetic switch valve 5, the inlet of external water source connecting pipeline 3 and flow detection pipeline 4 are communicated;The outlet of the flow detection pipeline 4 is communicated with electric reversing valve 6;The first outlet 7 of the electric reversing valve 6 is communicated with working inner container 1 by A water path 8;The second outlet 9 of the electric reversing valve 6 is communicated with the inlet and outlet water pipeline 20 of water tank 2 by B water path 10;

[0029] The inlet and outlet water pipeline 20 of the water tank 2 is also communicated with the inlet of a C water path 11;The outlet of the C water path 11 is communicated with the inlet of flow detection pipeline 4;First check valve 12 that the C water path 11 is provided with is unidirectionally guided to the inlet direction of flow detection pipeline 4.

[0030] Flow meter of flow detection pipeline 4 can be rotor flow meter, differential pressure flow meter, throttling flow meter, electromagnetic flow meter, slit flow meter, volume flow meter, electromagnetic flow meter, ultrasonic flow meter. External water source connected by external water source connecting pipeline 3 can be tap water or other pressurized water source. A electromagnetic switch valve 5 is preferably pilot operated electromagnetic valve, and the type of electric reversing valve 6 drive can be steering engine driven reversing valve, or electromagnetic coil driven electromagnetic valve;In internal liquid shunt, two-position three-way valve or three-position three-way valve can be selected;When two-position three-way valve is used, first outlet 7 is in normally closed state, and when three-position three-way valve is used, it can be switched from closed state to first outlet 7 or second outlet 9 conduction according to the actual water flow direction requirement, as follows:

[0031] When the water tank 2 is filled with water from the external water source, the A electromagnetic switch valve 5 is opened and the electrically operated reversing valve 6 is switched to the second outlet 9 in the on state, and the water flows through the flow detection pipeline 4, the second outlet 9, the B water path 10 into the water tank 2.

[0032] When the water tank 2 is filled with water from the external water source, the A electromagnetic switch valve 5 is opened and the electrically operated reversing valve 6 is switched to the second outlet 9 in the on state, and the water flows through the flow detection pipeline 4, the second outlet 9, the B water path 10 into the water tank 2.

[0033] When the water tank 2 is filled with water from the external water source, the A electromagnetic switch valve 5 is opened and the electrically operated reversing valve 6 is switched to the second outlet 9 in the on state, and the water flows through the flow detection pipeline 4, the second outlet 9, the B water path 10 into the water tank 2.

[0034] As shown in the embodiment 2: Figure 2

[0035] The difference between this embodiment and the embodiment 1 is that the water path system further comprises a water pump 13.

[0036] The water pump 13 is used to increase the flow of water into the working inner container 1 when the water tank 2 is draining water into the working inner container 1, and to reduce the draining time.

[0037] As shown in the embodiment 3: Figure 3

[0038] The difference between this embodiment and the embodiment 1 or the embodiment 2 is that the water path system further comprises a B electromagnetic switch valve 14.

[0039] The B electromagnetic switch valve 14 can independently turn on and off the water path from the water tank 2 and the C water path 11 to the working inner container 1. Due to the blockage of the B switch electromagnetic valve, the first outlet 7 can be in the always-on state and the second outlet 9 can be in the always-off state when the electrically operated reversing valve 6 is a two-position three-way electromagnetic valve. In this way, when the A electromagnetic switch valve 5 fails, the water from the external water source will directly enter the working inner container 1. Generally, the working inner container 1 of the washing equipment is provided with a strong drainage pump and a strong drainage triggering mechanism to drain the water to the external sewer pipeline, preventing the water from overflowing and flooding the entire washing equipment.

[0040] As shown in the embodiment 4: Figure 4

[0044] The difference between the embodiment and any one of the embodiments 1-4 is that the waterway system further comprises a third one-way valve 16; the third one-way valve 16 is installed in the B waterway 10 and unidirectionally communicated to the water inlet and outlet pipeline 20 of the water tank 2.

[0045] The third one-way valve 16 prevents the electrically operated reversing valve 6 from failure or leakage, and the water in the water tank 2 from leaking from the B waterway 10 to the working inner container 1.

[0046] As shown in the embodiment 6, Figure 6

[0047] The difference between the embodiment and the embodiment 1 is that the waterway system further comprises an encapsulation shell 17; the flow detection pipeline 4, the external water source connecting pipeline 3, the A waterway 8, the B waterway 10, the C waterway 11 and the first one-way valve 12 are all constructed in the encapsulation shell 17; and the A electromagnetic switch valve 5 and the electrically operated reversing valve 6 are both installed on the encapsulation shell 17.

[0048] On the basis of the embodiment 6, in combination with the embodiments 2-5, the water pump 13 and the B electromagnetic switch valve 14 are installed on the encapsulation shell 17, and the second one-way valve 15 and the third one-way valve 16 are both constructed in the encapsulation shell 17.

[0049] The flow detection pipeline 4, the external water source connecting pipeline 3, the A waterway 8, the B waterway 10, the C waterway 11, the first one-way valve 12, the second one-way valve 15 and the third one-way valve 16 are all constructed in the space inside the encapsulation shell 17, while the A electromagnetic switch valve 5, the electrically operated reversing valve 6, the B electromagnetic switch valve 14 and the water pump 13 are installed on the outside of the encapsulation shell 17, thereby avoiding the connection of the soft tubes, greatly improving the space utilization and reducing the risk of water leakage.
