Shower apparatus
First Claim
1. A shower apparatus comprising:
- a first hot water line extending from a source of hot water to a hot and cold water mixing valve;
a second hot water line connected to an outlet of said hot and cold water mixing valve and having at least one opening and closing valve connected to said second hot water line;
a third hot water line extending from each said at least one opening and closing valve to a respective shower discharging port;
a first drain valve disposed before said hot and cold water mixing valve in said first hot water line;
a first drain line extending from a drain port at a lower portion of the shower apparatus to said first drain valve;
an operation control section for controlling the operation of said at least one opening and closing valve and said drain valve; and
temperature sensing means for detecting a water temperature in said first hot water line;
said operation control section comprising first water disposal control means for opening said first drain valve when the temperature of the water in said first hot water line is lower than a predetermined level, thereby adding water to said first hot water line from said source of hot water until the temperature of water in said first hot water line rises to said predetermined level.

Abstract
The present invention is related to a shower apparatus provided with a plurality of shower discharge ports. More specifically, a shower apparatus is disclosed in which hot water remains in a hot water line connected to several shower discharge ports, after a discharge has been completed. Hot water within the hot water line which has lowered in temperature is drained through a drain valve in order to dispose of the water. At the beginning of the next shower discharge, cold water is prevented from being discharged. The operation of an opening and closing valve for effecting discharge and stoppage of each shower discharge port is controlled according to control programs, whereby the shower discharge is substantially controlled. The content of the shower discharge, carried out according to the programs, can be changed by a user through the operation of a central section. Moreover, upon the start of a shower discharge, a sudden jet of water is prevented.
