Water dispenser capable of continuously producing warm boiled water at preset temperature

Abstract

The invention discloses a water dispenser capable of continuously producing warm boiled water at preset temperature. A hot water tank (7) is located on the upper portion of a warm water tank (8), after hot boiled water enters the warm water tank (8) through a hot water tank drainage pipe (15), the temperature of the warm water tank (8) rises, after temperature measurement is conducted through a first temperature sensor (1), a second water inlet electromagnetic valve (22) is started, and a cooling medium enters a first heat exchange device (5) from a cooling medium inlet (20); when the second temperature sensor (2) reaches the set warm water outlet temperature value, water is discharged, when the first temperature sensor (1) reaches the set temperature, the second water inlet electromagnetic valve (22) is closed, and when the second temperature sensor (2) detects that the bottom water temperature is lower than the set temperature, heat exchange is stopped, and the auxiliary heating module (3) is started; and the temperature is increased to a set temperature through heating of the auxiliary heating module (3). Warm boiled water in a preset temperature range can be accurately provided, a large amount of water can be discharged, and the temperature of the warm boiled water can be adjusted and set by users.

Description

technical field [0001] The invention relates to the field of water dispensers, more specifically, to a water dispenser that continuously produces warm boiled water at a preset temperature. Background technique [0002] In real life, commercial, office and home environments often encounter a continuous demand for warm water with a set temperature range, especially in Asia, where a large number of users are used to drinking warm boiled water immediately after boiling and then cooled down. [0003] The current small water dispenser, one is to use normal temperature clean water inflow and hot clean water outflow to cool down through inner and outer casing heat exchange, the disadvantage is that the outlet water temperature is completely uncontrollable; the other is a warm water tank with a disc type The heat exchanger is used to exchange heat between the incoming water of normal temperature clean water and the hot water in the warm water tank before entering the hot water tank f...

AI Technical Summary

Problems solved by technology

[0003] The current small water dispenser, one is to use normal temperature clean water inflow and hot clean water outflow to cool down through inner and outer casing heat exchange, the disadvantage is that the outlet water temperature is completely uncontrollable; the other is a warm water tank with a disc type The heat exchanger is used to exchange heat between the incoming water of normal temperature clean water and the hot water in the warm water tank before entering the hot water tank for heating, thereby helping to cool it down. Since the amount of purified water replenished by a small water dispenser is less than the amount of water taken from the outlet (clean water The speed of water production is slow, and the amount of water produced by the machine is lower than the amount of water taken by the user at the same time). When the user continuously takes warm water, a large amount of hot water enters the warm water tank, and the heat exchange cannot be exchanged in time to cool down. The temperature of warm water rises sharply. The instant warm water volume of the temperature is small

There are also constant temperature drinking water institutions, such as constant temperature hot water bottles, which cannot supply water continuously, and the water volume is also difficult to meet the needs of public places for multiple times of constant temperature range warm water intake.
