Wall hanging stove waterway circulation control method, device and system

Abstract

The invention discloses a wall hanging stove waterway circulation control method, device and system. The method comprises the steps that after it is detected that domestic water is turned off, an operation mode of a wall hanging stove is obtained; according to the operation mode, an electric three-way valve is controlled to act to make the wall hanging stove carry out waterway circulation according to the mode of switching a major cycle of a heating system and a minor cycle of the heating system or according to the major circle mode of the heating system, wherein according to the major cycle of the heating system, water output by a water pump passes through a main heat exchanger, the electric three-way valve and the heat dissipating tail end in sequence and flows back to the water pump, and according to the minor cycle of the heating system, water output by the water pump passes through the main heat exchanger, the electric three-way valve and a plate heat exchanger in sequence and then flows back to the water pump. By means of the method, after the domestic water is turned off, waterway circulation can be carried out in the mode of switching the major cycle of the heating system and the minor cycle of the heating system or in the mode of the major cycle of the heating system, water stopping temperature rising of the wall hanging stove can be effectively relieved, the comfortableness of domestic water can be improved, and the use experience of users can be improved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a method, device and system for controlling water circulation of a wall-hung boiler. Background technique [0002] In the related technology, after the wall-hung boiler shuts off the domestic water, the wall-hung boiler adopts the circulation of the heating system of the wall-hung boiler to take away the excess heat absorbed by the main heat exchanger, so as to reduce the temperature rise of the water stop. [0003] However, for a plate-exchange wall-hung boiler, it not only has a main heat exchanger, but also a plate heat exchanger. The plate heat exchanger is a heat exchanger for heating domestic water, and the heat inside it is not taken away. Therefore, Using the above method on a plate-replacement wall-hung boiler, although it has a certain effect, the temperature rise will still reach about 13K-15K without water, and the comfort of using water is poor again, which red...

[0003] However, for a plate-exchange wall-hung boiler, it not only has a main heat exchanger, but also a plate heat exchanger. The plate heat exchanger is a heat exchanger for heating domestic water, and the heat inside it is not taken away. Therefore, Using the above method on the plate-replacement wall-hung boiler, although it has a certain effect, the temperature rise will still reach about 13K-15K without water, and the comfort of water is poor again, which reduces the user experience.
