Abstract
The utility model discloses an exhaust fan installation structure of a wall-hanging stove. The exhaust fan installation structure comprises a casing, wherein a combustion chamber is arranged in the casing, and a combustor is installed under the combustion chamber; a heat exchanger is installed in the combustion chamber, and a smoke vent is formed in a top plate of the combustion chamber; an exhaust fan is installed on the top plate of the combustion chamber, the exhaust inlet of the exhaust fan is communicated with the smoke vent, and the exhaust outlet of the exhaust fan is communicated with an air outlet of the top plate of the casing; the top plate of the combustion chamber is obliquely arranged, and the side face of the top end of the combustion chamber is triangular. The exhaust fan is installed on the top plate of the combustion chamber, so that the need for installation space is met, and the smoke exhausting space is the top of the whole combustion chamber. The heat exchanger is not locally parched, the smoke is uniformly dispersed and exhausted, and the service life of the heat exchanger is prolonged.
Description
Technical field
the utility model relates to wall-hung boiler field, is specifically related to a kind of exhaust blower mounting structure of wall-hung boiler.
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.In the casing of top, combustion chamber, will leave the position that exhaust blower is installed, as shown in Figure 1, so top board anterior downward bending depression in original combustion chamber forms step surface, exhaust blower is arranged on the step surface of top board.The combustion chamber of structure like this, exhaust opening is confined at the small space near backboard place, combustion chamber, be arranged at last root heat exchanger tube of this position, under long-term vehement baking, therefore service life, large heavy discount, arranged a baffle plate at exhaust opening place, and waste gas is from the left and right of baffle plate and the discharge that is uniformly dispersed of the space of top, but effect is still undesirable, still fragile near the heat exchanger position at baffle plate periphery place.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of exhaust blower mounting structure of wall-hung boiler, exhaust blower is arranged on the combustion chamber top board being obliquely installed, without baffle plate setting, the top that smoke evacuation space is whole combustion chamber, heat exchanger is not subject to local vehement roasting, the smoke evacuation that is uniformly dispersed, increases service life of heat exchanger.
The utility model is achieved through the following technical solutions:
A kind of exhaust blower mounting structure of wall-hung boiler, comprise casing, in casing, be provided with combustion chamber, below, combustion chamber is provided with burner, and heat exchanger is installed in combustion chamber, combustion chamber top board is provided with exhaust smoke hole, on the top board of combustion chamber, exhaust blower is installed, the inlet scoop of exhaust blower is communicated with exhaust smoke hole, and the exhaust outlet of exhaust blower is communicated with the exhaust outlet of casing top board, described combustion chamber top board is obliquely installed, and side, top, combustion chamber is triangular in shape.
The further improvement project of the utility model is that described combustion chamber top board and horizontal line angle are 30-45 degree.
The utility model compared with prior art, has following obvious advantage:
Combustion chamber described in the utility model top board is obliquely installed, and side, top, combustion chamber is triangular in shape.Exhaust blower is arranged on the combustion chamber top board of inclination, has both met the needs of installing space, and the top that is whole combustion chamber, smoke evacuation space, and heat exchanger is not subject to local vehement roasting, the smoke evacuation that is uniformly dispersed, the service life of increase heat exchanger.
Accompanying drawing explanation
Fig. 1 is prior art structure chart.
Fig. 2 is the utility model structure chart.
The specific embodiment
As shown in Figure 2, the exhaust blower mounting structure of a kind of wall-hung boiler described in the utility model, comprise casing 1, in casing 1, be provided with combustion chamber 2,2 belows, combustion chamber are provided with burner 3, heat exchanger 4 is installed in combustion chamber 2, combustion chamber top board 21 is provided with exhaust smoke hole 22, exhaust blower 5 is installed on combustion chamber top board 21, the inlet scoop of exhaust blower 5 is communicated with exhaust smoke hole 22, the exhaust outlet of exhaust blower 5 is communicated with described combustion chamber top board 21 with the exhaust outlet 11 of casing top board and is obliquely installed, with horizontal line angle be 30-45 degree, 2 sides, top, combustion chamber are triangular in shape.
