It is possible that the collecting and the distribution pipe to fill in the form of a channel box, which has a partition wall. However, it must be ensured that the partition wall separates the water box tightly into an input and an output-side section.
  • partitions are used in the prior art, which divide the water tank into two subspaces. There is the problem that the partitions are possible cost-saving and nevertheless sealing inserted into the collection box.
