Because the water routes of the prior multi-drum washing machine are more, the circulating water routes of the multi-drum washing machine are more complex, and the prior multi-drum washing machine needs to adopt more components and parts and is realized by a plurality of electromagnetic valves. At least two washing barrels are arranged in the multi-barrel washing machine, at present, the circulation of washing water in the two washing barrels and the flowing and redistribution of the washing water between the two washing barrels need to be controlled by arranging a plurality of electromagnetic valves in a water path of the multi-barrel washing machine, the assembly cost of the multi-barrel washing machine is greatly increased, meanwhile, the arrangement of the electromagnetic valves also occupies a large assembly space, and the size of the multi-barrel washing machine is increased.
As shown in fig. 1 to 5, in order to adopt the structure of the multi-way valve employed in the washing water recycling system of the multi-drum washing machine in the present embodiment, the first and second multi-way valves employed in the present embodiment each adopt the structure of the rotary multi-way valve as shown in fig. 1 to 5. The structure of the rotary multi-way valve in this embodiment is described in detail below:
as shown in fig. 1-5, in this embodiment there is disclosed a rotary multi-way valve comprising: a housing 1, a valve core 2 and a drive assembly 3. The shell 1 adopts a long cylindrical structure; the valve core 2 is rotatably arranged in the shell 1 along the axial direction of the long cylinder of the shell, and adopts a columnar structure; the driving assembly 3 is arranged on one side of the valve core and drives the valve core 2 to rotate in the shell 1.
To realize the matching communication between the shell 1 and the valve core 2. A housing inlet 101 is provided on an upper peripheral surface of the housing 1, and a plurality of housing outlets are provided on a lower peripheral surface (the upper peripheral surface and the lower peripheral surface are arranged in opposition to each other, and the relative relationship between the housing inlet 101 and the housing outlets is merely for convenience of explanation). When the liquid inlet 101 of the shell realizes the liquid outlet function, the liquid outlet of the shell realizes the liquid inlet function.
Correspondingly, a plurality of valve core liquid inlets which are communicated with the shell liquid inlet 101 are formed on the peripheral surface of the valve core 2; and a plurality of valve core liquid outlets communicated with the plurality of shell liquid outlets are formed. The multiple valve core liquid inlets and the multiple valve core liquid outlets are in one-to-one correspondence, a flow channel is formed between each valve core liquid inlet and each valve core liquid outlet in each group, and the flow channels between the groups are mutually independent. The flow channels are not communicated with each other and are only connected with the valve core liquid inlet and the valve core liquid outlet which are mutually corresponding.
Because the valve core 2 is rotatably arranged in the shell 1, when the valve core 2 is driven by the driving component 3 to rotate to different preset angles, an inlet and an outlet of a flow channel in the corresponding valve core are corresponding to and communicated with the shell liquid inlet 101 and the shell liquid outlet according to preset rules. The preset rule refers to that at any preset angle, an independent flow channel is correspondingly arranged on the valve core, the inlet of the flow channel is communicated with the inlet of the shell, the outlet of the flow channel is communicated with the outlet of the shell, the communication mode realizes independent communication, and at the moment, other flow channels cannot be communicated with the inlet of the shell.
In some alternative implementations, the upper circumferential surface of the housing 1 is provided with one housing inlet 101, the lower circumferential surface is provided with three housing outlet ports, and the three housing outlet ports are, from left to right, a first housing outlet port 102, a second housing outlet port 103 and a third housing outlet port 104. 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. 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.
