Meanwhile first water inlet access water inlet through the first Venturi tube 2A enter the second constant volume container 4B, due to second text
Venturi 2B does not have water flow process, so negative pressure is not generated in the second negative tube 3B, without negative pressure in the second constant volume container 4B, and
Three check valve 6C are closed, and after the second constant volume container 4B is full of water flow, it is negative that the second float valve 5B blocks the second constant volume container 4B and second
The communication port of pressure pipe 3B, the 4th check valve 6D are opened under the action of water pressure, and water flows through the second water outlet 10B and enters cylindric washer；
As shown in fig. 6, inlet valve control the second water inlet access water inlet, the water of the second water inlet access flow through the second Venturi tube
2B enters the first constant volume container 4A, and second one-way valve 6B is opened under the action of water pressure, the water flow dilution first of the second water inlet access
Liquid detergent in constant volume container 4A is simultaneously flushed in cylindric washer, and during which, the first water inlet access does not stop intaking, and guarantees that second is fixed
Hold and remain full water state in container 4B, the second float valve 5B blocks the second negative tube 3B and the second constant volume container 4B, third list
It is closed to valve 6C.
According in cylindric washer laundry amounts and/or cloth and/or dirt degree and/or inlet water temperature and/or water quality calculate
Laundry liquid measure to be added is needed, and then calculates the number for entering constant volume container using water flow negative pressure extracting cleaning solution.
Example IV
As shown in Figs 1-4, the present embodiment is as further limiting to embodiment three, discloses that the following are into washing machine
The step of launching softener.
Inlet valve control the second water inlet access is first intake, and water flow flows through the second Venturi tube 2B into the first constant volume container
4A generates negative pressure in the second negative tube 3B, generates negative pressure in the second constant volume container 4B being connected to the second negative tube 3B, and second
Check valve 6B is opened, and the second suction pipeline 8B connection simultaneously extracts softener from the second detergent container 9B to the second constant volume container
4B；
When second constant volume container 4B is full of softener, the second float valve 5B blocks the second constant volume container 4B and the second negative tube 3B
Communication port, there is no negative pressure in the second constant volume container 4B, second one-way valve 6B is closed；
Meanwhile second water inlet access water inlet through the second Venturi tube 2B enter the first constant volume container 4A, due to first text
Venturi 2A does not have water flow process, so negative pressure is not generated in the first negative tube 3A, without negative pressure in the first constant volume container 4A, and
One check valve 6A is closed, and after the first constant volume container 4A is full of water flow, it is negative that the first float valve 5A blocks the first constant volume container 4A and first
The communication port of pressure pipe 3A, second one-way valve 6B are opened under the action of water pressure, and water flows through the first water outlet 10A and enters cylindric washer；
Inlet valve control the first water inlet access water inlet, the water of the first water inlet access flow through the first Venturi tube 2A into second
Constant volume container 4B, the 4th check valve 6D are opened under the action of water pressure, and the water flow of the first water inlet access dilutes the second constant volume container 4B
Interior softener is simultaneously flushed in cylindric washer, and during which, the second water inlet access does not stop intaking, and is guaranteed in the first constant volume container 4A
Remain that full water state, the first float valve 5A block the first negative tube 3A and the first constant volume container 4A, the first check valve 6A closing.
According in cylindric washer laundry amounts and/or cloth and/or dirt degree and/or inlet water temperature and/or water quality calculate
Submissive dosage to be added is needed, and then calculates the number for entering constant volume container using water flow negative pressure extracting softener.
