Specifically, the method comprises the following steps: the rotary multi-way valve comprises: the valve comprises a shell, a valve core and a driving assembly, wherein the shell is in a long cylinder shape; the valve core is arranged in the shell in a rotatable manner along the axial direction of the long cylinder of the shell; the driving assembly is arranged on one side of the valve core and drives the valve core to rotate in the shell. The upper circumferential surface of the shell is provided with a shell liquid inlet, and the lower circumferential surface of the shell is provided with a plurality of shell liquid outlets; a plurality of valve core liquid inlets communicated with the shell liquid inlets and a plurality of valve core liquid outlets communicated with the plurality of shell liquid outlets are formed on the peripheral surface of the valve core; the plurality of valve core liquid inlets and the plurality of valve core liquid outlets are in one-to-one correspondence and form independent flow channels; when the valve core is driven by the driving assembly to rotate to different preset angles, the inlet and the outlet of one corresponding flow channel in the valve core correspond to and are communicated with the shell liquid inlet and the shell liquid outlet according to preset corresponding rules.

As shown in fig. 4 to 8, when the multi-way valve is a three-way valve, a housing inlet 101 is disposed on an upper peripheral surface of the housing 1, and three housing outlets are disposed on a lower peripheral surface of the housing 1, and the three housing outlets are a first housing outlet 102, a second housing outlet 103, and a third housing outlet 104 in a left-to-right sequence (the sequence is for convenience of explaining the structure of the three-way valve, and is only a matter of convenience in the drawings, and is not limited to the left-to-right sequence, but may be other angles or orientation sequences). Specifically, the flow channels in the valve core 1 include a first flow channel 203, a second flow channel 204, and a third flow channel 205, and the first flow channel, the second flow channel, and the third flow channel are not on the same plane, wherein: the first flow passage is provided with a first through hole A207 and a first through hole B208 on the circumferential surface of the valve core; the second channel is provided with a second through hole A029 and a second through hole B210 on the circumferential surface of the valve core; the third flow passage has a third through hole a211 and a third through hole B212 formed in the valve body peripheral surface.

The valve core forms a first notch 201 between the first through hole A207 and the position corresponding to the shell liquid inlet 101, and forms a second notch 202 between the second through hole A209 and the position corresponding to the shell liquid inlet 101. Because a shell liquid inlet is shared, in order to ensure that the runners are not communicated with each other, the first notch 201 and the second notch 202 can be formed in a staggered mode so that the first notch 201 and the second notch 202 are not communicated with the shell liquid inlet 101 at the same time, and the third through hole A211 is also not communicated with the first notch 201 and the second notch 202 in a staggered mode.

In some implementations, the first and

second flow passages

203, 204, and the third flow passage 205 are open in a radial direction of the spool. At this time, the radial direction corresponding to each opened flow passage may be different. The valve core structure can be more regular by arranging the flow channel in the radial direction, uneven thickness of two sides of the valve core flow channel due to the offset flow channel can be avoided, damage caused by abrasion after long-time use can be prevented, and the service life of the valve core is prolonged by the structure.

The three flow passages are isolated by the four sealing rings, so that the condition that water is mutually communicated due to poor sealing property between the shell and the valve core is avoided.

Further optionally, a first sealing ring supporting bridge 213 is disposed on the first notch 201, and a second sealing ring supporting bridge 214 is disposed on the second notch 202. Because sealing washer 4 is mostly softer material, if adopt materials such as rubber, it has certain deformation, supports the bridge through two sealing washers and can support the sealing washer of the left and right sides respectively, has avoided leading to the gap between sealed case that can not be better and the casing because sealing washer atress warp, causes sealed effect not good.

In order to improve automation and reduce manpower to realize automatic control, the driving assembly comprises a motor and can drive the valve core to rotate to a preset angle in the shell to form different passages. And a sealing washer is arranged between the motor and the valve core, so that water is prevented from overflowing the three-way valve and even burning the motor.

A cylinder bottom 105 is arranged at one end of the housing far away from the driving component 3, and since the valve element needs to rotate in the housing, in some implementations, a positioning support groove 106 is arranged on an inner side surface of the cylinder bottom 105, a positioning column 206 is arranged at an axial center of one end of the valve element 2 close to the cylinder bottom 105, and the positioning column 206 is assembled in the positioning support groove 106.

The opening direction of the first flow channel 203 and the opening direction of the third flow channel 205 can be 90 degrees, at this time, the third flow channel and the second flow channel can also be 90 degrees, that is, an inlet and three outlets on the shell are both located on the same plane.

The opening state of the three outlets can adopt the following modes:

(1) when the motor is in a power-off state, the third flow channel is in an open state, and the corresponding first flow channel and the corresponding second flow channel are not communicated with the corresponding shell liquid outlet;

(2) when the motor rotates forward by 90 degrees (rotates 90 degrees towards one side) when the motor is electrified, the first flow channel is in an open state, namely, the notch of the first flow channel is communicated with the liquid inlet of the shell, the second flow channel is parallel to the first flow channel, but the second notch of the second flow channel is not communicated with the liquid inlet of the shell, and the third flow channel is not communicated with the liquid outlet of the shell;

(3) when the motor rotates 90 degrees in a reverse direction (rotates 90 degrees towards the other side) when the motor is electrified, the second flow channel is in an open state, namely, the notch of the second flow channel is communicated with the liquid inlet of the shell, although the first flow channel is parallel to the second flow channel, the first notch of the first flow channel is not communicated with the liquid inlet of the shell, and the third flow channel is not communicated with the liquid outlet of the shell.

Through this rotation type three-way valve, can realize switching the communicating pipe way of three-way washing machine.

In some other alternative implementations, the motor of the multi-way valve is a stepping motor, and the detergent is controlled to be dosed by converting an electric pulse signal received by the stepping motor into a corresponding angular displacement. Or other switching valves provided with stepping motors are adopted to switch pipelines.
