Problems solved by technology
At this time, because the pressure difference formed in the air pressure switch is different when the fan is running at different speeds, only one air pressure switch will not be able to ensure the safety of the gas wall-hung boiler at different operating speeds of the fan.

Embodiment Construction
[0019] The present invention will be described below by way of specific embodiments. It is to be understood that the specific embodiments are provided only for the purposes of convenient understanding of the invention, and is not intended to limit the invention. Thus, the following examples are merely exemplary, and the scope of the invention is limited only by the appended claims.
[0020] figure 1 The configuration of the wind pressure switch assembly in the prior art is shown schematically. As shown, the wind pressure switch assembly includes a wind pressure switch 1, a compression device 2, and a connecting tube 3 connecting the wind pressure switch 1 and the compression device 2, the connecting pipe 3 including a positive pressure tube 3a. And the negative pressure tube 3b.
[0021] The wind pressure switch 1 typically includes a positive pressure detection port 1a and a negative pressure detection port 1b, and the cavity thereby is also divided into a positive pressure cham...

The invention discloses a wind pressure switch assembly, a gas wall-hanging stove comprising the wind pressure switch assembly and a control method for the gas wall-hanging stove. The wind pressure switch assembly is used for the gas wall-hanging stove comprising a fan with a plurality of running speeds, and comprises a plurality of wind pressure switches, a pressure tapping device and a connecting pipe. A first detection port of each of the plurality of wind pressure switches communicates with a first pressure tapping port of the pressure tapping device through a first connecting pipe, and a second detection port of each of the plurality of wind pressure switches communicates with a second pressure tapping port of the pressure tapping device through a second connecting pipe; and each of the plurality of wind pressure switches corresponds to each of a plurality of operation speeds of the fan, and the starting pressure difference / shutdown pressure difference of each of the plurality of wind pressure switches is set according to the corresponding one of the plurality of operation speeds of the fan. The wind pressure switch assembly can ensure the use safety of the gas wall-hanging stove at a plurality of operation speeds of the fan.
Description
Technical field [0001] The present invention relates to a gas wall mounting furnace, and more particularly to a wind pressure switch assembly for gas wall mount furnace, including a gas wall mounting furnace of the wind pressure switch assembly and a control method thereof. Background technique [0002] Gas wall hanging foors typically include a fan and a wind pressure switch assembly used in combination with the fan. When the wind turbines unexpectedly, the speed reduction or the inclined passage clogging causes insufficient exhaust or unable to vent, the wind pressure switch will automatically disconnect. Therefore, the control unit stops the gas wall to stop operation to ensure the safety of the gas wall. [0003] The wind pressure switch assembly in conventional gas wall hangs typically includes only one wind pressure switch (i.e., a wind pressure sensor) having a set of boot pressure differences and shutdown pressure differences (ie on / OFF points), and the power-on pressur...
