Dual-purpose furnace and control method of dual-purpose furnace

Abstract

The invention relates to a dual-purpose furnace. The dual-purpose furnace comprises a heating water pipeline, a heat exchanger and a domestic water pipeline, and is characterized by further comprisinga water supplementing pipeline, a water supplementing valve, a first temperature sensor and a controller; and the water supplementing pipeline is connected between the water inlet end and the water outlet end of the domestic water pipeline, the water supplementing valve is arranged on the water supplementing pipeline, the first temperature sensor is arranged on the water outlet section of the domestic water pipeline, and the controller is electrically connected with the water supplementing valve and the first temperature sensor. According to the dual-purpose furnace, cold water is actively supplemented into the water outlet section of the domestic water pipeline through the water supplementing pipeline, so that the use comfort is met, and a user is prevented from being scalded. Accordingto the control method of the dual-purpose furnace, on the basis that active water supplementing can be achieved, in addition, in the intermittent process that a user uses domestic water, water circulation can be performed through a domestic water circulation loop, and rapid cooling of water in the domestic water pipeline can be achieved through the switching conduction mode between a heating circulation loop and a hot water circulation loop, so that when a user uses water, the temperature of the output domestic water is reduced to the set temperature.

Description

technical field [0001] The invention relates to the technical field of dual-purpose furnaces, in particular to a control method for preventing high temperature of re-outlet water of a dual-purpose furnace, and the invention also relates to a dual-purpose furnace applying the method. Background technique [0002] At present, most of the dual-purpose stoves circulating on the market are upward-drawing dual-purpose stoves. The main functions of the upward-drawing dual-purpose stoves are heating and bathing. The dual-purpose heating furnace includes a heating circulation loop and a domestic outlet water circulation loop, and the dual-purpose heating boiler usually uses a plate heat exchange method to exchange heat for domestic water, and then forms hot water to supply users with domestic water. When the dual-purpose boiler is in use, domestic hot water is usually given priority. When the dual-purpose boiler is in the working state of domestic hot water, the heating part will sus...

AI Technical Summary

Problems solved by technology

[0004] The first technical problem to be solved by the present invention is to provide a method that can actively reduce the water temperature in the domestic water pipeline when the water temperature in the water outlet section of the domestic water pipeline is detected to be too high, thereby preventing the user from using The water temperature is too high when the domestic hot water is used to improve the user experience of the dual-purpose stove
