Description

  The present invention relates to a shower apparatus having a function of removing residual water (cold water) before starting use of a shower.

  Conventionally, there is a shower device that jets a shower (hot water) into a bathroom provided with a bathtub.

  Such shower devices include a hot water type that ejects a shower from the ceiling and a body shower type that ejects a shower from a side wall. In addition, the shower injection method includes intermittent straight injection, continuous straight injection, spray injection, mist injection, and the like.

  Since the previous residual water remains as cold water in the shower device, at the start of use of the shower, until the hot water is supplied from the water heater, a shower of cold water is jetted from the shower into the bathroom. As a result, cold water is applied to the body, which may cause discomfort.

  Then, the shower apparatus provided with the function to remove residual water (cold water) before the start of use of a shower is proposed (refer to patent documents 1).

By the way, there is no problem if the removed residual water (cold water) can be drained out of the bathroom (outside) as it is, but there are many cases where it is necessary to drain into the bathroom. And when draining in the bathroom, a drain outlet is provided in the bathroom side wall panel near the bathtub pan, or a drain outlet is provided in the bathroom side wall panel near the washing area.
