Specific embodiment
For help those skilled in the art definitely understand this application claims theme, with reference to the accompanying drawing in detail
The specific embodiment of the application is described.
Shown in Figure 1, in order to save space, it is empty as introducing that Household gas-fired wall-mounted furnace generallys use balanced flue 30
The pipeline of gas and discharge flue gas, is commonly known as balanced type wall-hung boiler using the burnt gas wall hanging furnace of this type flue.This field
It is known that balanced flue 30 is the double-deck concentric pipe for being configured with inner tube 31 and outer tube 32, inner tube 31 surrounds itself technical staff
The first airflow channel for flue gas to be discharged, the second airflow channel that the interlayer between outer tube 32 and inner tube 31 is formed is used to suck
Fresh air provides burning.Wherein, the outlet end 31a of inner tube 31 stretches out outer tube end 32a certain distance, to reduce discharge
A possibility that flue gas is inhaled into furnace again by outer tube 32.Air filter 40 in present embodiment is to be set in
Except inner tube 31, what the air that the second airflow channel for being formed to interlayer between outer tube 32 and inner tube 31 sucks was filtered
Device.
Specifically, balanced type Household gas-fired wall-mounted furnace generally includes blast tube 10, wall hanging with burnt gas valve 73
Furnace main body 20 and the balanced flue 30 being arranged in outside the wall hanging furnace main body 20, which is configured with concentric
Inner tube 31 and outer tube 32.Combustion chamber 23, heat exchanger 24 are additionally provided with above burner 22 inside the wall hanging furnace main body 20,
And the blower 25 being connected with heat exchanger 24, the first airflow channel that outlet end and the said inner tube 31 of the blower 25 surround
Connection, the blast tube 10 and the second airflow channel are connected to the arrival end of the burner 22, on balanced flue 30
It is provided with air filter 40.
In conjunction with shown in Fig. 1 and Fig. 2, in this embodiment, the main body 45 of the air filter 40 is by air
Cross section made of filtering material is the cylinder of annulus.The size of the internal diameter R of the annulus allows the main body 45 to be set in institute
The outside of the inner tube 31 of balanced flue 30 is stated, and the ring width d of the annulus ensures to flow through the gas of second airflow channel
The main body 45 is both passed through to be cleaned.As shown, the outer tube 32 can be split as the main body 45 positioned at air filter 40
The first segment of top and the second segment below the main body 45 of air filter 40, i.e., the main body 45 of the described air filter 40
Between the first segment and second segment of outer tube 32.
It is understood that the air filting material due to selection may have certain elasticity, in other embodiment
In, the axially hollow shape of main body 45 is also possible to other shapes according to the shape difference of filtering material difference and inner tube 31
Shape.
In order to further facilitate the dismounting and cleaning of air filter 40, in feasible embodiment, the air mistake
The annular of the cross section of the main body 45 of filter 40 is connected by multiple fan rings, that is to say, that the main body 45 is main by multiple sons
Body composition, it be that each sub- main body of fan ring is successively connected and is formed that the annulus of 45 cross section of main body, which is by cross section, these described sons
At least one is detachable end among the cohesive end of main body.Shown in Figure 2, in this embodiment, the son is main
Body 41,42 quantity are for two and equal in magnitude, that is to say, that it is half that the main body 45 of the air filter 40, which is by two cross sections,
The sub- main body 41,42 of annulus is connected.One cohesive end 40a of this two sub- main bodys 41,42 is to be connected using fastener
Detachable end, another cohesive end 40b are the hub switch side being connected using pivotal part.The cohesive end 40a of the main body can be with as a result,
It is turned on or off using cohesive end 40b as axis, installs, clears up and dismantle on flue convenient for air filter 40.As preferable
Embodiment, cohesive end 40a, 40b setting sealing strip 44 between two sub- main bodys 41,42 are to prevent gas from leaking.
It is bonded in order to facilitate the installation of and with pipeline closely, in this embodiment, the periphery also ring of the main body 45
It is provided around protective shell 43, the top margin of the protective shell 43 and bottom edge exceed the top and bottom height of the main body and edge respectively
The axial direction of the main body extends to form extension 43a.The protective shell 43 is made for example, by using flexible plastic material, outer tube 32
First segment and the part that is in contact with air filter main body 45 of second segment be extended a section 43a and covered, and in extension 43a
Seal washer 44 is arranged in portion, plays further sealing effect.The air filting material that main body 45 uses is wire or plastics
Strainer made of fibrous material is conveniently replaceable and clears up.In other embodiments, air filter 40 can also be all arranged
In interlayer i.e. the second airflow channel between outer tube 32 and inner tube 31, it is arranged or is not provided with protective shell, in this case, outside
Pipe 32 is not necessarily intended to be split as two sections, can be an entirety.But for present embodiment, to air mistake
Filter 40 carries out periodic cleaning will be relatively difficult.
Shown in Figure 1, which further comprises connects respectively with the water inlet pipe 83 of domestic water and outlet pipe 82
The plate heat exchanger 21 connect；It is respectively connected with hot water outlet pipe 81, plate heat exchanger 21 and the heat exchanger 24 of heating water
Triple valve 71；And water pump 72 being connected with the cold water water inlet pipe 84 of heating water etc..Due to the basic principle of Domestic wall furnace
It is well known to the skilled person with working method, details are not described herein again.
The air filter of the application and Domestic wall furnace structure are simple as a result, are convenient to clean, and can effectively filter sky
The impurity contained in gas avoids them from entering in burner or heat exchanger the service life for influencing wall-hung boiler.
Although having been shown and described the application based on specific embodiment, the application is not restricted to shown thin
Section.On the contrary, the various details of the application can be modified in the range of claim and its equivalent replacement.
