a water boiler

Abstract

The invention relates to a water boiler. A pressure relief pipeline and a water inlet pipeline are connected, a pressure relief container and a water return pump are additionally arranged on the pressure relief pipeline, and therefore water vapor in the pressure relief process is collected into the pressure relief container and then returns into the water inlet pipeline through the water return pump to be reutilized, the problems about sanitation, safety and the like caused by direct discharge of the water vapor in the pressure relief process of the water boiler are avoided, water resource waste is reduced, the energy utilization rate is increased, and the water boiler is really convenient to use, healthy, safe and environment-friendly and saves energy. In addition, a water return pipeline is integrated into the pressure relief pipeline, water remaining in a water outlet pipeline and water in the pressure relief container can be pumped into the water inlet pipeline together, and therefore the structure of the water boiler is simplified, and the work efficiency and the energy utilization rate are increased; and in addition, it is ensured that the water boiler can provide boiled water at a set temperature for a user at any time, the boiled water is heated only once, and healthy drinking water is guaranteed.

Description

technical field [0001] The invention relates to the field of drinking water equipment, in particular to a water boiler. Background technique [0002] With the improvement of people's living standards and the acceleration of the pace of life, as well as the pursuit of a healthy life, the requirements for drinking water are gradually increasing, and higher requirements are also put forward for the safety of use. Currently, there are drinking water equipment on the market. The following defects: [0003] In order to protect the safety of the inner tank, the existing water boiler mainly adopts the traditional pressure relief method, such as adding a pressure relief valve. When the pressure or temperature reaches the pressure, the water vapor pressure is directly discharged to the outside of the inner tank to protect the inner tank. However, direct discharge of water vapor has disadvantages, such as: bacteria are easy to grow near the drain steam outlet, which may seriously affe...

[0003] In order to protect the safety of the inner tank, the existing water boiler mainly adopts the traditional pressure relief method, such as adding a pressure relief valve. When the pressure or temperature reaches the pressure, the water vapor pressure is directly discharged to the outside of the inner tank to protect the inner tank. However, direct discharge of water vapor has disadvantages, such as: bacteria are easy to grow near the drain steam outlet, which may seriously affect the health of drinking. In addition, because it is directly discharged, water vapor is easy to hurt people, causing safety hazards. Hidden danger
