Flow channel swiching device, and shower unit having the same

Abstract

A flow path switching device comprising two flow paths having pressure losses different from each other, and a valve body provided corresponding to one of the two flow paths which has a lower pressure loss, the two flow paths being switched by opening/closing the flow path having the lower pressure loss with the valve body, and a shower unit having the flow path switching device. It is possible to provide a low pressure-loss flow path switching device for which it is not necessary to open/close the two flow paths at the same time and which is simple in construction and can save space. Further, if this flow path switching device is used in a purified water shower unit having a raw water flow path and a purified water flow path, then it is possible to provide a purified water shower unit which ensures that switching operation can be performed easily by one hand, that a filter material can sufficiently maintain its shape even when water pressure is applied to the filter material, that the filter material is worn off efficiently over the whole, and that space in the unit is efficiently used.
