HOT AND COLD WATER DISPENSER

摘要

PURPOSE: A hot- and cold-water dispenser is provided to enhance cooling and heating efficiency by stably preventing the back flow of hot water and steam. CONSTITUTION: A hot- and cold-water dispenser comprises a working plate(200) and a check valve(300). The working plate is arranged in a cold-water tank and divides the cold-water tank into a room-temperature-water chamber and a cold-water chamber. A hot-water connecting pipe is formed on the center of the working plate. Purified water is supplied to a hot-water tank through the hot-water connecting pipe. The check valve prevents the hot water from flowing backward from the hot-water tank to the cold-water tank. The check valve is detachably installed in the hot-water connecting pipe in a fitting way. The check valve closes the hot-water connecting pipe with the elastic force.
