Description

An energy-saving circulation type double water temperature water boiler

technical field

The invention relates to a drinking water device, in particular to an energy-saving circulating double water temperature water boiler utilizing cold and hot water to exchange heat.

Background technique

The water boiler is a relatively common device in our daily life. It is small in size, fast in heating speed, easy to use, and can provide hot water anytime and anywhere, especially in schools, hospitals, factories, enterprises and other places where crowds are concentrated. It has been widely used in daily life. But there are many defects in the traditional water boilers on the market now:

The traditional water boiler generally adopts the water storage heating method. The tap water is heated to the boiling point of 100°C and then automatically stops to complete the heating process. The tap water needs to use a high-power heating element and is continuously heated to 100°C, which is extremely power-consuming and not energy-saving. Environmental protection, in the modern era of corresponding green world and sustainable development, will eventually be eliminated; at the same time, there are many problems in various aspects of traditional water boilers:

1. Drinking problem: Due to the limitation of the water boiler body, the traditional water boiler cannot guarantee to provide boiled water at 100°C, so the heated water may not really reach the boiling point, and may not be really drinkable.

2. Temperature problem: Even if the water temperature is continued to 100°C, due to insufficient heat preservation of the water tank, the heat loss is relatively fast, and there is a large waste of resources. Drinkers drink it, but as far as the actual situation is concerned, although due to differences in seasons and personal physiques, the best drinking water temperature for the human body is different, but it is definitely not boiling at 100°C. If you directly drink boiled water in a traditional water boiler, the temperature If it is too high, it is easy to burn the drinker, and high temperature water is not suitable in summer.

3. The problem of thousand boiling water: when the temperature of the boiling water drops to a certain temperature value, the traditional water boiler will automatically start to reheat, which will make the remaining boiling water in the water boiler that has been boiled but not drunk be boiled repeatedly, forming Thousand-boiling water, this kind of water is boiled for a long time, and the non-volatile substances in the water, such as calcium, magnesium and other heavy metal components and nitrite, are very high, which is easy to breed bacteria. Drinking this kind of water for a long time will interfere with human gastrointestinal function , Severe cases will cause hypoxia, coma, convulsions, and even death, which will cause great harm to the human body.

4. Yin-yang water problem: When traditional water boilers are heated, cold water and hot water are not independent. After part of the boiled water is used, the new cold water and the remaining boiled water are easily mixed to form yin-yang water, which affects the taste and endangers health.

Although there are instant electric kettles on the market to achieve instant heating and instant drinking, the designed water storage tank of about 2L has a small capacity and requires frequent water addition, which is inconvenient to use, and the steam generated during the heating process will cause pyrolysis of the plastic shell. , so as to produce plasticizers, so that the taste of plastic in the water will not only affect the taste but also cause harm to human health.

In view of the defects of repeated heating of residual boiled water in the current water boiler equipment, time-consuming and energy-consuming defects, combined with actual production and use needs, based on the current situation of my country's industry, how to provide a new generation of products that are more energy-saving, environmentally friendly, safe and reliable is the primary problem to be solved .
