Description

Wall-mounted gas stove with wind pressure detection device

Technical Field

The utility model relates to a gas hanging stove, specific use square wind pressure pipe and then prevent that comdenstion water from blockking up the gas hanging stove that has a wind pressure detection device of wind pressure pipe that says so.

Background

The gas wall hanging stove has a powerful household central heating function, can meet the heating requirements of multiple rooms, can set comfortable temperature at will in each room according to the requirements, can also decide to independently close heating in a certain room according to the requirements, and can provide large-flow constant-temperature sanitary hot water for occasions such as household bathing and kitchens.

Because of the adoption be gas combustion as the heat source, need guarantee it and exhaust and admit air, wherein, admit air and rely on wind-powered electricity generation exhaust to form the negative pressure in the combustion chamber and realize, so, admit air and exhaust and rely on the work of single fan to realize, if fan work is unusual or the wind channel is unsmooth, probably cause the incident, for the safe work of guaranteeing gas hanging stove, when starting and in service, all need detect the exhaust wind pressure in wind channel.

The current wall-mounted gas stove mainly uses a wind pressure switch or a wind pressure sensor to detect whether a fan and a wind channel are in a normal working state, the working principle is that the wind pressure switch or the wind pressure sensor is connected to a pressure taking port of the fan through a wind pressure pipe, and whether the fan and the wind channel work normally is judged by detecting the change of pressure difference.

In the actual operation process, because the burning characteristic decision of hanging stove, contain vapor in the combustion product flue gas after the gas burning, vapor mixes in the flue gas, when passing through the wind pressure pipe transmission pressure differential, under partial condition (like under the low-load burning, outdoor air temperature is lower etc. the vapor can be at the intraductal condensation of wind pressure and produce the comdenstion water, along with the extension of live time, the comdenstion water can constantly gather, can lead to the comdenstion water to block up the wind pressure pipe finally, make wind pressure check components such as wind pressure switch can't inspect the wind pressure, and then hanging stove can't normally work.

And for the model that partly uses the wind pressure switch, the comdenstion water that the condensation was appeared also probably can get into the wind pressure switch along with the flue gas, because of the contact during the wind pressure switch, the transmission signal of telecommunication, the entering of comdenstion water can lead to the wind pressure switch mistake to report the trouble, makes hanging stove unable normal work.

In summary, the industry needs to provide a wall-mounted gas boiler capable of preventing condensed water in a wind pressure pipe from condensing and collecting.
