Water-temperature-adjustable three-water-outlet water purifier extension set and control method thereof

Abstract

The invention relates to a water-temperature-adjustable three-water-outlet water purifier extension set and a control method thereof. The extension set comprises a water inlet electromagnetic valve, awater purifying tank, a heating water tank, three two-in-one draining electromagnetic valves and an electric control device, wherein the water inlet electromagnetic valve is connected with an external purified water source; a high liquid level probe and a low liquid level probe are mounted in the water purifying tank; and a heating pipe, an anti-dry-heating controller and a temperature sensor aremounted in the heating water tank, the water purifying tank and the heating water tank are correspondingly connected with the three two-in-one draining electromagnetic valves through pipelines, and the top of the heating water tank is communicated with the bottom of the water purifying tank through a water inlet pipeline. According to the water-temperature-adjustable three-water-outlet water purifier extension set, hot water or warm water is selected by opening cold or hot electromagnetic valves in the two-in-one draining electromagnetic valves, the water temperature of hot water in the heating water tank is within a set range, and the temperature fluctuation is very small, so that the bacteria breeding can be inhibited; and water at multiple temperatures can be obtained, and can be simultaneously discharged by virtue of three water outlet nozzles.

Description

technical field [0001] The invention relates to a three-outlet water purifier extension with adjustable water temperature and a control method thereof, specifically, it can provide safe and sterile direct-drinking purified water, can select different outlet water temperatures, and realizes the purification of three water outlets simultaneously. A water dispenser extension and a control method thereof belong to the field of water dispenser equipment. Background technique [0002] At present, water boilers are often used in public places to provide medium-temperature water, which is obtained through so-called cold and heat exchangers. The temperature fluctuates greatly, and constant temperature water cannot be realized. Traditional hot and cold water dispensers use the structure of a water storage tank and a heating tank. The water storage tank is used to provide normal temperature water. However, if the normal temperature water is not sterilized after being stored for a long...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the water purifier extension is generally required in the following three situations: 1. The user’s water purifier is equipped with a pressure tank but has no heating function; 2. The user who has pre-filtered the tap water needs to provide hot water; 3. 1. There is a water-making module installed in the water dispenser. Because of the loud noise of the booster pump, it is not suitable for relatively quiet office and meeting places.

At present, most of the water outlets of wall-mounted water purifiers are one or two water outlets, which is not conducive to receiving water at the same time for more than two people. In public places, when there are many drinkers, they even need to queue up, which brings some inconvenience to the water purifier.
