Full-automatic two-water-temperature water boiler

Abstract

The invention discloses a full-automatic two-water-temperature water boiler. The full-automatic two-water-temperature water boiler comprises a heat insulation box body, a heating box, a heat exchange box, a warm boiled water storage box and a preheated water storage box, wherein the heating box, the heat exchange box, the warm boiled water storage box and the preheated water storage box are located in the heat insulation box body; an electric heater with a temperature controlled switch is arranged in the heating box; the temperature of boiled water in the heating box is lowered after heat exchange through the heat exchange box, then the boiled water enters the warm boiled water storage box, meanwhile, the temperature of cooling water in the heat exchange box is increased after heat exchange, then the cooling water enters the preheated water storage box, and when the liquid level in the heat box is lowered, the preheated water in the preheated water storage box enters the heating box. The full-automatic two-water-temperature water boiler can provide boiled water and warm boiled water with the temperature being 50-70 DEG C; and a mechanical device is adopted by the full-automatic two-water-temperature water boiler for replacing an electronic control device, thus, the reliability of the whole system is higher, the expansion coefficient of used gas or volatile solvents is high, cooling of the boiled water and preheating of cold water are achieved through the siphoning effect, electric energy and heat energy are saved, and the potential safety hazards caused by electricity usage are avoided.

Description

technical field [0001] The invention relates to a fully automatic double-temperature water boiler, which belongs to the technical field of mechanical design. Background technique [0002] Most of the water boilers on the market are single-temperature water boilers with an outlet temperature close to 100℃. In the process of cooling the boiled water, the heat of the boiled water is dissipated in vain and has not been effectively recovered or utilized, and the energy utilization rate of the water boiler is low. [0003] Considering the above problems, there are currently water boilers on the market that have water outlets at nearly 100°C and normal temperature. However, the water boiler takes a long time to fetch water each time because it is difficult to mix the appropriate water temperature, and in public places, especially campuses, the flow of people is large and the action time is concentrated, so there is a problem of low water fetching efficiency when it is used in this...

Problems solved by technology

However, the water boiler takes a long time to fetch water each time because it is difficult to mix the appropriate water temperature, and in public places, especially on campus, the flow of people is large and the action time is concentrated, so there is a problem of low water fetching efficiency when it is used in this occasion

On the other hand, the control system and circuit of the dual-temperature water boiler in the prior art are relatively complicated, and the operating temperature of the water boiler is relatively high, which poses a challenge to the reliability of the control system and circuit, further reducing the reliability of the entire system
