Abstract
The utility model discloses an air inlet-outlet channel structure of a wall hanging stove. An air inlet is formed in a casing of the wall hanging stove, an air inlet channel is arranged in the casing and communicated with a burner, a combustion chamber of a heat exchanger is mounted above the burner, and communicated with an exhaust opening of an exhaust fan of which an air outlet is communicated with an exhaust pipe arranged at the top end of the casing, an air inlet channel is a space sealing channel reserved between a casing back plate and a combustion chamber back plate, and the channel is directly communicated to an ignition induction needle position of the burner. According to the utility model, the air inlet channel is arranged at the rear part, and the ignition induction needle position of the burner is directly communicated for the matching with an installation position of the burner, so that a one-time supply air rate is increased, the one-time mixed combustion effect is high, a fuel utilization rate is improved and the generated amount of carbon monoxide waste gas is lowered.
Description
Technical field
the utility model relates to fuel wall hanging formula heating stove field, and what be specifically related to wall-hung boiler enters air exhaust passage structure.
Background technology
Burnt gas wall hanging furnace has powerful Domestic central heating function, and comfort temperature can be arbitrarily set in each room according to demand, and large flow constant temperature health hot water can be provided, for places such as Household shower bath, kitchens.To using natural gas, artificial coal gas or liquefied gas as fuel, fuel is exported through burner, after burning Indoor Combustion, by heat exchanger by heat absorption, recirculated water in heating system is when by way of heat exchanger, thereby through heating in reciprocating mode, constantly heat is exported to building, for building provides thermal source; The carbon monoxide waste gas producing in combustion chamber is communicated with outside discharge duct discharge chamber by exhaust blower.The abundant efficient burning of fuel, there is direct relation with igniting inductive needle position fuel and the air degree of mixing of burner, air air inlet duct in the past is generally surrounded by inner casing biside plate and shell, be positioned at casing two side positions, air enters burner position, because the igniting inductive needle position of burner is in lower bottom part, the igniting inductive needle position of only having part air flow burner, one time intake is little, the surface of most of air flow burner, form secondary air mixed combustion, thereby fuel firing rate is low, the carbon monoxide exhausted air quantity that burning forms is large.
Summary of the invention
What the technical problems to be solved in the utility model was to provide a kind of wall-hung boiler enters air exhaust passage structure, air intake passage is located at back, coordinate burner installation site, directly be communicated with the igniting inductive needle position of burner, increase by one time intake, mixed once combustion efficiency is high, improves fuel availability, reduces carbon monoxide waste gas generation.
The utility model is achieved through the following technical solutions:
Wall-hung boiler enter air exhaust passage structure, described wall-hung boiler casing is provided with air inlet, in casing, be provided with air intake passage, air intake passage is communicated to burner position, the top of burner is the combustion chamber that heat exchanger is installed, and combustion chamber is communicated with the inlet scoop of exhaust blower, and the exhaust outlet of exhaust blower is communicated with the discharge duct that casing top arranges, described air intake passage is the space sealing passage leaving between computer case back plate and combustion chamber backboard, and passage is directly communicated to the igniting inductive needle position of burner.
The further improvement project of the utility model is that described air inlet concentric is arranged at discharge duct periphery.
The utility model compared with prior art, has following obvious advantage:
The utility model, due to air intake passage is located to back, coordinates burner installation site, is directly communicated with the igniting inductive needle position of burner, increase an intake of air, mixed once combustion efficiency is high, improves fuel availability, reduces carbon monoxide waste gas generation.
Accompanying drawing explanation
Fig. 1 is the utility model side view.
The specific embodiment
As shown in Figure 1, wall-hung boiler described in the utility model enter air exhaust passage structure, described wall-hung boiler casing 1 top board is provided with air inlet 12, in inner casing 1, be provided with air intake passage 2, air intake passage 2 is communicated to burner 3 positions, the top of burner 3 is the combustion chamber 4 that heat exchanger is installed, combustion chamber 4 is communicated with the inlet scoop of exhaust blower 5, the exhaust outlet of exhaust blower 5 is communicated with the discharge duct 6 that casing 1 top arranges, described air intake passage 2 is the space sealing passages that leave between computer case back plate 11 and combustion chamber backboard 7, passage has directly connected igniting inductive needle 31 positions that pass to burner 3.Described air inlet 12 concentrics are arranged at discharge duct 3 peripheries.
During operation, the air inlet 12 that air enters from casing enters in casing, along air intake passage 2, most of air directly flows to igniting inductive needle 31 positions of burner 3, forms one time intake, burns with fuel mix, improve fuel availability, reduce the discharge of carbon monoxide waste gas.
