Common-source split-cavity multi-temperature sterile large-supply-amount water drinking device and water and temperature supplementing method thereof

Abstract

The invention relates to the field of direct water dispensers, in particular to a common-source multi-cavity multi-temperature sterile large-supply-amount water dispenser and a water and temperature supplementing method thereof.The common-source multi-cavity multi-temperature sterile large-supply-amount water dispenser comprises a water purifying device which comprises a purified water inlet and a purified water outlet; the heating device comprises a hot tank, a hot water inlet formed in the hot tank, a hot water outlet formed in the hot tank, a boiled water nozzle formed in the hot tank and a stepping type electric heating device, and the hot water inlet is communicated with the purified water outlet; the heat preservation device comprises a heat preservation water tank, a heat preservation water inlet formed in the high position of the heat preservation water tank, a heat preservation water outlet formed in the low position of the heat preservation water tank and a warm water nozzle arranged on the heat preservation water tank, and the heat preservation water inlet communicates with the hot water outlet; the circulating device comprises a circulating water pump and a third electromagnetic valve communicated with the circulating water pump, the circulating water pump is communicated with the heat preservation water outlet, the third electromagnetic valve is communicated with the hot water inlet, and the heat preservation water outlet, the third electromagnetic valve and the circulating water pump are sequentially communicated.

Description

technical field [0001] The present application relates to the field of direct drinking water machines, in particular to a common-source, divided-cavity, multi-temperature aseptic large-volume drinking water device and a water replenishing and warming method thereof. Background technique [0002] Facing the increasingly serious environmental pollution, "drinking water safety" has become the demand of all mankind. The safety factors of drinking water are usually divided into two categories: physical and chemical indicators and microbiological indicators. Physical and chemical pollution has already been fully guaranteed by mature purification technologies (reverse osmosis, nanofiltration, etc.), and the most critical and difficult to achieve is the microbial index (such as the total number of colonies, total coliforms, etc.). Coupled with the fact that microorganisms have the ability to reproduce independently, how to ensure the safety of microbial hygiene indicators for direc...

Problems solved by technology

[0003] At present, in order to meet the needs of users, a hot water tank / heating tank (100°C) and a warm water tank / water storage tank (45°C) are installed, and water is supplied to the warm water tank through the hot water tank. However, when the warm water tank The temperature of the warm water will gradually drop after no one uses it for a long time. It is difficult to meet the needs of users to keep warm water at any time. At the same time, it also faces safety risks caused by the autonomous reproduction of microorganisms.
