Drinking water system with automatic water adding function and safety control method thereof

Abstract

The invention relates to a drinking water system with an automatic water adding function and a safety control method thereof. A water inlet pipeline and a drainage pipe are connected to one side of an unboiled water barrel, a heating pipeline and a condensation pipe are connected between the unboiled water barrel and a hot water barrel, and a plurality of sections of first water level switches and second water level switches for detecting the water level are arranged inside the unboiled water barrel and the hot water barrel, so that the heating pipeline is controlled to add boiled water into the hot water barrel automatically. When the second water level switches fail efficacy, the condensation pipe leads overflowing boiled water into the unboiled water barrel, for the reason that the first water level switches are provided with multiple security mechanisms such as a dry burning-resistant mechanism and a full water level emergency outage mechanism, when the first water level switches also fail efficacy, water in the unboiled water barrel can be led out by the drainage pipe due to overflowing, and accordingly the safety drinking water system with a non-pressure non-vapor service environment can be created. According to the invention, boiled water can be automatically added, the multiple security mechanisms such as the dry burning-resistant mechanism and the full water level emergency outage mechanism are achieved, and therefore the explosive danger of the drinking water system is avoided.

Description

technical field [0001] The invention relates to a drinking water system, especially a drinking water system with automatic water replenishment and safety control method that can automatically heat cold water and supplement boiled water, and is equipped with multiple safety mechanisms such as anti-dry boiling, emergency power-off when the water level is full, and the like. Background technique [0002] like Figure 8 As shown, it is Taiwan Utility Model Patent No. 209581 "Water Heating Device for Drinking Machine", which discloses that the raw water tank 91 of the drinking machine 9, and the boiling water tank 93 or hot water tank 92 are respectively equipped with detection elements SW1, SW2, the detection elements SW1, SW2 can sense the height of the water level, and control the start of the heating device 94, so that when the water level of the warm water cylinder 93 and the hot water cylinder 92 is lower than the position of the detection element inside, it can control the ...
