Abstract

The invention provides a wind pressure pipe, a wall-mounted furnace and a method of reducing a using failure of the wall-mounted furnace, and relates to the technical field of the wall-mounted furnaces. The technical problems that the failure rate is high and the after-sales maintenance cost is high in the using process of the wall-mounted furnace in the prior art are solved. The wind pressure pipe comprises pipe bodies and condensed water discharge devices; the condensed water discharge devices are arranged on the pipe bodies; condensed water outlets and air flow outlets are formed in the pipe bodies; the air flow outlets are connected with a wind pressure switch; and the condensed water discharge devices can discharge condensed water precipitated by condensing an air flow in the pipe bodies out of the pipe bodies from the condensed water outlets. The failure rate of the wall-mounted furnace is reduced, and the after-sales maintenance cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of wall-hung boilers, in particular to a wind pressure pipe, a wall-hung boiler and a method for reducing malfunctions of the wall-hung boiler. Background technique

[0002] At present, in the industry of gas heating water heaters (hereinafter referred to as wall-hung boilers), wind pressure switches (or wind pressure sensors) are often used to detect whether the fans and air ducts are in normal working conditions.

[0003] The air pressure switch is connected to the pressure port of the fan through the air pressure pipe. By detecting the change of pressure difference, it can be judged whether the fan and air duct are working normally; however, due to the combustion characteristics of the wall-hung boiler, the combustion product smoke after gas combustion The gas contains water vapor, and the water vapor is mixed in the flue gas. When the pressure difference is transmitted through the air pressure pipe, in s...
