DETAILED DESCRIPTION OF THE EMBODIMENTS

Example 1

[0042] The detergent dosing controller refers to FIG. 1, equipped with main passage 1, one side is water inlet 101, another side is outlet 102 connecting to liquid inlet of washing bucket, valves A2, B3, C4, D5, pump 6 and nozzle 7 are equipped. Inlet of valve A connects to the bypass orifice Aa of the main passage; inlet of valve B connects to liquid storage tank of detergent A; outlets of valve A and valve B connect to inlet of valve C; inlet of valve D connects to liquid storage tank of detergent B; outlets of valve C and valve D connect to inlet 601 of the pump; outlet 602 of pump connects to bypass orifice Bb of the main passage. Relative location of bypass orifices A and B of main passage: bypass orifice A is relatively close to inlet 101 of main passage, bypass orifice B is relatively close to outlet 102 of main passage. The inlet diameter of the nozzle is smaller, while outlet diameter is the bigger, this nozzle connects to main passage by concatenation and between bypass orifices A and B, nozzle inlet faces to the inlet of main passage, while outlet faces to the outlet of main passage.

[0043] When the valve B3 and valve C4 are open, valve A2 and valve D5 are closed, pump 6 is started, detergent A will be sucked into main passage; when valve A and valve D are open, valve B and valve C are closed, the pump is started, detergent B will be sucked into main passage. Opening time of valve B and valve D can be controlled, namely the detergent dosing quantity can be controlled.

[0044] When valve A2 and valve C4 are open, valve B3 and valve D5 are closed, if main passage inlet 101 connects to water source, with the action of nozzle 7, water pressure at bypass orifice Aa will be higher than that at bypass orifice Bb, therefore, a bypass flow that flows from bypass orifice A to bypass orifice B can flush and clean the bypass passage.

Example 2

[0045] The detergent dosing controller is equipped with main passage 1, one side is water inlet 101, another side is outlet 102 connecting to liquid inlet of washing bucket. It is equipped with an integrated valve as shown in FIG. 3 and FIG. 4. The integrated valve is equipped with valve A with inlet A201 and valve seat A202, valve B with inlet B301 and valve seat B302, valve C with inlet C401 and valve seat C402 and valve D with inlet D501 and valve seat D502. The integrated valve has chamber 1 (10) and chamber 2 (14), when valve seat A is under open state, chamber 1 connects to inlet A201, when valve seat C is under open state, chamber 1 connects to chamber 2. Chamber 2 has an outlet 1401, inlet A connects to bypass orifice Aa of main passage, outlet 1401 of chamber 2 connects to bypass orifice Bb of main passage. Bypass orifice A is relatively close to inlet 101 while bypass orifice B is relatively close to outlet 2. A nozzle is set between bypass orifice A and B of main passage, its inlet faces to the inlet of main passage, outlet faces to the outlet of main passage; this integrated valve is equipped with solenoid valve assembly 1 and 2; solenoid coil 1 (13) is equipped in solenoid valve assembly 1, in the guide sleeve, plunger 1 (12) is equipped and its front end connects to plunger cap 1 (11); solenoid coil 2 (17) is equipped in solenoid valve assembly 2, in the guide sleeve, plunger 2 (16) is equipped and its front end connects to plunger cap 2 (15);

[0046] The valve A and valve B correspond to solenoid valve assembly 1, valve seat A202 and valve seat B302 connect to chamber 1 (10) of integrated valve and face to axis in this chamber, keeping certain distance away from the axis, plunger cap 1 of solenoid valve assembly 1 is within the distance scope of valve seat A and valve seat B. Under normal state, plunger cap 1 can close valve seat B while open valve seat A, this normal state refers to non-energized state of solenoid coil 1.

[0047] The valve C and valve D correspond to solenoid valve assembly 2, valve seat C402 and valve seat D502 connect to chamber 2 (14) of integrated valve and face to axis in this chamber, keeping certain distance away from the axis, plunger cap 2 of solenoid valve assembly 2 is within the distance scope of valve seat C and valve seat D. Under normal state, plunger cap 2 can close valve seat D while open valve seat C, this normal state refers to non-energized state of solenoid coil 2.

[0048] In this example, valve A and valve B are interlinked; valve C and valve D are interlinked. When solenoid coil 1 (13) is not energized, plunger 1 (12) stretches out under the action of rear spring, plunger cap 1 (11) closes the valve seat B302 and opens valve seat A202, inlet A201 connects to chamber 1 (10); similarly, when solenoid coil 2 (17) is not energized, plunger 2 (16) stretches out under the action of rear spring, plunger cap 2 (15) closes the valve seat D502 and opens valve seat C402, chamber 1 (10) connects to chamber 2 (14). Under the above conditions, when the solenoid coil is energized, plunger 1 is closed, plunger cap 1 (11) closes seat valve A202 and opens valve seat B302, detergent A is fed. Similarly, the energized solenoid coil 2 can make detergent B fed.

[0049] In this example, valve A and valve B are interlinked; valve C and valve D are interlinked. Closing or opening of valve seats A, B, C and D refers to closing or opening of valves A, B, C and D.

[0050] When valve A is open, valve B is inevitably closed; when valve A is closed, valve B is inevitably open. Similarly, when valve C is open, valve D is inevitably closed; when valve C is closed, valve D is inevitably open.

[0051] When valve A is closed, valve B is open; when valve C is open, valve D is closed, pump is started, detergent A is sucked into main passage. When valve A is open, valve B is closed; when valve C is closed, valve D is open, pump is started, detergent B is sucked into main passage. The opening time of valve B and valve D can be controlled, namely detergent dosing quantity can be controlled.

[0052] When valve A and valve C are open, valve B and valve D are closed, the main passage inlet connects to water source, with the action of nozzle, water pressure at bypass orifice A will be higher than that at bypass orifice B, therefore, a bypass flow that flows from bypass orifice A to bypass orifice B can flush and clean the bypass passage.

Inlet A201 connects to bypass orifice Aa of main passage, when valve seat A is open, chamber 1 connects to inlet A201. When valve seat C is open, chamber 1 connects to chamber 2. Outlet 1401 in chamber 2 connects to pump inlet 601, pump outlet 602 connects to bypass orifice Bb of main passage. Bypass orifice A is relatively close to main passage inlet, while B is relatively close to main passage outlet. A nozzle is set between bypass orifices A and B of main passage, its inlet faces to the inlet of main passage, its outlet faces to the outlet of main passage; solenoid valve assembly 1 and solenoid valve assembly 2 are equipped at lower part of integrated body; solenoid coil 1 (13) is equipped in solenoid valve assembly 1, in the guide sleeve, plunger 1 (12) is equipped and its front end connects to plunger cap 1 (11); solenoid coil 2 (17) is equipped in solenoid valve assembly 2, in the guide sleeve, plunger 2 (16) is equipped and its front end connects to plunger cap 2 (15);

[0054] The valve A and valve B correspond to solenoid valve assembly 1, valve seat A202 and valve seat B302 connect to chamber 1 (10) of integrated valve and face to axis in this chamber, keeping certain distance away from the axis, plunger cap 1 of solenoid valve assembly 1 is within the distance scope of valve seat A and valve seat B. Under normal state, plunger cap 1 can close valve seat B while open valve seat A, this normal state refers to non-energized state of solenoid coil 1.

[0055] The valve C and valve D correspond to solenoid valve assembly 2, valve seat C402 and valve seat D502 connect to chamber 2 (14) of integrated valve and face to axis in this chamber, keeping certain distance away from the axis, plunger cap 2 of solenoid valve assembly 2 is within the distance scope of valve seat C and valve seat D. Under normal state, plunger cap 2 can close valve seat D while open valve seat C, this normal state refers to non-energized state of solenoid coil 2.
