Embodiment 1

[0044] Such as Figure 1-Figure 7 Shown:

[0045] A wind pressure pipe provided by the present invention includes a pipe body 1 and a condensed water discharge device 4 arranged on the pipe body 1. The pipe body 1 is provided with a condensed water outlet and an air outlet, and the air outlet is used for When connected to the air pressure switch 2 , the condensed water discharge device 4 can discharge the condensed water condensed and precipitated by the airflow in the pipe body 1 from the condensed water outlet to the outside of the pipe body 1 .

[0046] In the air pressure pipe provided by the embodiment of the present invention, the condensed water discharge device 4 can discharge the condensed water that is condensed and precipitated by the airflow in the pipe body 1 from the condensed water outlet to the outside of the pipe body 1; The air pressure switch 2 is short-circuited due to the condensed water blocking the air pressure pipe or the condensed water entering the a...

Embodiment 2

[0059] Such as Figure 8 Shown:

[0060] The difference between Embodiment 2 and Embodiment 1 is that the condensed water discharge device 4 is a corrosion-resistant heat conduction member 401 inserted at the condensed water outlet of the pipe body 1, and the heat conduction member 401 is inserted obliquely, and At least the lower end of the heat conducting element 401 is inserted at the condensed water outlet of the pipe body 1 and protrudes outside the pipe body 1 (preferably both ends of the heat conducting element 401 protrude outside the pipe body 1).

[0061] As an optional implementation manner, the heat conduction member 401 is a heat conduction wire (preferably a heat conduction wire with a diameter of 0.5mm-1.5mm) or a heat conduction sheet.

[0062] As an optional embodiment, the heat conducting member 401 is made of Q215, Q235 (preferably Q235), Q255, No. 08 steel, No. 10 steel, No. 15 steel, No. 20 steel, No. 40 steel or No. 45 steel.

[0063] In this embodiment...

Embodiment 3

[0068] Such as Figure 9 with Figure 10 Shown:

[0069] The difference between this embodiment 3 and embodiment 1 is that the condensed water discharge device 4 is a drain pipe obliquely connected to the condensed water outlet, one end of the drain pipe extends into the pipe body 1, and the other end of the drain pipe The one-way valve 7 is connected, and the end connected with the one-way valve 7 is lower than the end extending into the pipe body 1; when installing the wall-hung boiler, the end of the drain pipe connected with the one-way valve 7 protrudes out of the sealed chamber 5 outside.

[0070] As an optional embodiment, the end surface of the end of the drainage pipe protruding into the pipe body 1 is inclined, the top of this end is flush with the inner wall of the pipe body 1 , and the bottom of this end extends into the pipe body 1 .

[0071] As an optional embodiment, the internal diameter of the drain pipe is 2.0mm-3.0mm (preferably 2.5mm); since the cross-se...

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...
