Wall-mounted furnace

Abstract

The invention provides a wall-mounted furnace which comprises a heating device, a domestic water system, a heat exchange water pipeline and a backflow pipeline. The domestic water system is provided with a domestic water inlet, a domestic water outlet, a living water heated section heated by a first heat exchanger, a first living water branch section located between the living water inlet and theliving water heated section and a second living water branch section located between the living water outlet and the living water heated section, and a first circulation water pump is arranged on thefirst living water branch section. The heat exchange water pipeline is provided with a first heater, and comprises a heat exchange water heating section arranged in the first heat exchanger and exchanging heat with the living water heated section, a first heat exchange water branch section communicating with the first living water branch section and located on the upstream position of the first heater, a second heat exchange water branch section located on the downstream position of the first heater and located on the upstream position of the heat exchange water heating section, and a heat exchange water return connection section enabling the heat exchange water heating section to communicate with the first heat exchange water branch section. The two ends of the backflow pipeline communicate with the first living water branch section and the second living water branch section correspondingly, and the backflow pipeline is provided with a water return valve.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a wall-hung boiler. Background technique [0002] The wall-hung boiler is a dual-purpose boiler, which has the functions of heating and domestic hot water. However, most of the existing wall-hung boilers adopt the principle of giving priority to domestic hot water, that is, when using the hot water function, the heating function needs to be stopped, and heating cannot be performed. When people need heating and hot water at the same time, especially in the cold winter, if domestic hot water is used for a long time, the temperature of the water in the heating pipeline will decrease, which will reduce the user experience and lead to unnecessary energy consumption . [0003] In addition, when using domestic hot water, as the length of the user pipeline increases, the user has to wait for a long time before using the hot water, and the hot water can only be released afte...

[0002] The wall-hung boiler is a dual-purpose boiler with heating and domestic hot water functions, but most of the existing wall-hung boilers adopt the principle of domestic hot water priority, that is, when the hot water function is used, the heating function needs to be stopped, and heating cannot be performed

When people need heating and hot water at the same time, especially in the cold winter, if domestic hot water is used for a long time, the temperature of the water in the heating pipeline will decrease, which will reduce the user experience and lead to unnecessary energy consumption

[0003] In addition, when using domestic hot water, as the length of the user pipeline increases, the user has to wait for a long time before using the hot water, and the hot water can only be released after the cold water in the pipeline is emptied, which affects the user experience
