Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the utility model is further described:

[0017] The function of the gas wall-hung boiler is divided into two states: heating and domestic water supply. First, the heating working state is introduced. When the keyboard is set to heating, when the NTC probe senses that the water temperature is lower than the set temperature, the circulating water pump starts and the water flow switch closes. The microcomputer detects whether the flow reaches the starting value within 30S, and if it does not reach the starting value, it enters into the fault display and fault handling program. When the flow reaches the starting value within 30 seconds, enter the next step, start the fan, and clean up before combustion. The microcomputer detects that the air pressure switch is closed within 10S, and the closing time is ≥10S, the solenoid valve and the gas proportional valve are opened, and the ignition program is entered. At the same time, t...

Abstract

The gas burning wall hanged furnace as one improved small household gas-burning boiler features its control system, which has temperature detector, flame detector, water flow detector and alarm connected to the CPU to provide input signal, and circulating water pump, exhaust controller, igniter and solenoid valve connected to the CPU to receive output signal; the heat exchanger, which is connected to water pump, plate heat exchanger, water return pipe, T-valve, water outlet pipe and automatic air exhaust valve; and the plate heat exchanger with connected water inlet pipe and water outlet pipe for domestic water. The present invention has the advantages of microcomputer control, simple operation, and separation between domestic water and heating water.

Description

Technical field: [0001] The invention belongs to the technical field of heating devices and relates to the improvement of a small domestic gas boiler. Background technique: [0002] At present, the domestic gas-fired boiler is mainly an open expansion tank, that is, the system water is connected to the atmosphere through the opening of the expansion tank, and the heating system water expands when heated and contracts when cooled. Its disadvantages are affecting thermal efficiency, poor heat dissipation effect, high noise, short life and so on. Invention content: [0003] The purpose of the present invention is: [0004] Provided is a gas wall-hung boiler which is automatically controlled by a computer and has multi-point repeated safety protection. [0005] Technical scheme of the present invention is: [0006] In the control system, temperature detection, flame detection, water flow detection, and alarm display are connected to the CPU as input signals, and the circula...
