In this embodiment, the integrated waterway expands the water inlet channel 11 and the water outlet channel 12 through the first chamber 13 and the second chamber 14, respectively, so that the integration level of the integrated waterway is improved while the water inlet channel 11 and the water outlet channel 12 are ensured to be communicated with the corresponding modules respectively.

As shown in fig. 2, a water intake control mechanism 21 may be provided in the housing 1. The water inlet control mechanism 21 can communicate with the first chamber 13. Specifically, the inlet of the inlet control mechanism 21 may be in communication with the first flow passage 31 to communicate with a water source or other water supply unit. The outlet of the water inlet control mechanism 21 communicates with the first chamber 13 so that water that has not been softened can be made to enter the first chamber 13. The first flow passage 31 may be formed on the housing 1. The first flow channel 31 may extend in the length direction of the housing 1. The first flow passage 31 may communicate with the first chamber 13 through the water inlet control mechanism 21.

In the forward washing mode, the water outlet control mechanism 22 and the first flush water outlet mechanism 23 are in a closed state. The water inlet control mechanism 21 and the second flushing water outlet mechanism 24 are in an open state. In other modes, the second flush outlet mechanism 24 is in a closed state.

At least one of the water inlet control mechanism 21, the first flushing water outlet mechanism 23, the water outlet control mechanism 22 and the second flushing water outlet mechanism 24 may be provided as a single unit.

Referring to fig. 7E, when the water softener is in the normal washing mode, the water outlet control mechanism 22, the control device 72, and the first flush water outlet mechanism 23 are in a closed state. The water inlet control mechanism 21 and the second flushing water outlet mechanism 24 are in an open state. The water enters the first flow channel 31 from the first opening 61 of the first water channel, passes through the first chamber 13, enters the inlet of the resin tank 82 from the second opening 62 of the first water channel, enters the water outlet channel from the second opening 62 of the second water channel after the resin in the resin tank 82 is subjected to forward washing compression, and then flows out through the second chamber 14 and the second flushing water outlet mechanism 24.

second housings

16 and 17 are connected, the first and

third passages

161 and 171 communicate to form a first flow passage 31, and the second and

fourth passages

162 and 172 communicate to form a second flow passage 32. The third channel 171 has opposed first and second

For example, the third opening portion 175 and the first opening portion 173 may be located on the left side wall of the second case 17. The second open portion 174 and the fourth open portion 176 are located on an upper sidewall of the second case 17.

The first shell 16 and the second shell 17 may be detachably connected by bolts, plugging, clamping, or the like. Wherein at least one of the first shell 16 and the second shell 17 is variable in size. To accommodate different sizes of resin cans 82, the size of the first shell 16 and/or the second shell 17 may be varied based on the requirements of the resin cans 82 to avoid interference during assembly.

For example, the first and

second channels

161, 162 may extend along the length of the first shell 16. As the size of the resin tank 82 becomes larger, a longer first shell 16 may be employed.
