Water supply device of direct drinking water terminal

Abstract

The invention discloses a water supply device of a direct drinking water terminal, which comprises a centre purifying water generating device and drinking water machines which are arranged at a plurality of supplying points, wherein the drinking water machines ate connected with the centre purifying water generating device through water conveying pipes; and the centre purifying water generating device comprises a purifying water generating device and a large type water storing tank for supplying water. The water supply device is characterized in that each drinking water machine comprises a one-way valve, a sealing water storing pressure tank, a hot water faucet with an instantaneous heating device and a cold water faucet with a cold water pot, wherein the water outlet of the one-way valve is respectively connected with the inlet and the outlet of the sealing water storing pressure tank, the hot water faucet with the instantaneous heating device and the cold water faucet through the water conveying pipes. Compared with the prior art, the water supply device has the capability of constant voltage water supply, can prevent bacteria from breeding, can not heat up the water for many times, is energy-saving, and can meet the requirements of water pressure, water quality and water quantity of each supplying point in whole working condition and whole time.

Description

Technical field: [0001] The invention relates to a drinking water supply device. Background technique: [0002] The terminal water supply device of the existing direct drinking water system is generally converted from a traditional barreled water dispenser. This type of drinking water device is equipped with a special water storage tank, and most of them use a non-airtight container that can be in contact with the air. Over time, it will breed Bacteria that are harmful to the human body cause secondary pollution of clean water. Moreover, in order to ensure that the water temperature in the water storage tank is constant at a temperature close to boiling, the water in the water storage tank must be heated repeatedly to become thousand boiling water, and thousand boiling water will Produce some substances harmful to human body. Technically speaking, the principle of the hot and cold water outlet head of this water dispenser is that the height difference between the water tank...
