Description
Technical field
The present invention relates to field of water heaters, more particularly to a kind of exhaust fume collecting hood and the combustion gas with the exhaust fume collecting hood are hot
Hydrophone.
Background technology
Also known as gas water-heating furnace, it refers to using combustion gas as fuel, by combustion heating mode to gas heater
A kind of gas appliance of the purpose for transferring heat to prepare hot water in the cold water for flow through heat exchanger to reach.
It is mainly and is made up of valve body assembly, burner, heat exchanger (also referred to as water tank), exhaust fume collecting hood etc..
Valve body assembly controls the working procedure of whole water heater, and it includes water valve, air valve, microswitch and igniting
Device etc..There can be fire row in burner, flue gas be produced by combustion gas, in flue gas heat exchanger
After water, discharged through smoke exhaust pipe after being assembled by exhaust fume collecting hood.However, gas heater is when northern winter uses
Time often has water tank by the phenomenon of bursting by freezing, and it is that main cause is that outside cold air leads to cause this infringement
The smoke exhaust pipe for overheating hydrophone enters inside gas heater, caused by the water-ice in water tank heat exchange pipe is frozen.
To solve this problem, most gas heater is utilized in water tank outer coils, intaking connects
Head and water out adapter position install antifreeze adding thermal resistance additional.But the defect of this method is, the position of freezing be
The inside of gas heater, and antifreeze adding thermal resistance cannot be internally heated to gas heater, it is difficult to thorough
Bottom solves water tank to be occurred by the phenomenon of bursting by freezing.Some gas heater is utilized in being set in smoke exhaust pipe
Down-draught-proof baffle arrangement, in the weather of the big severe cold of wind, cold air to be blocked in the outside of gas heater.
But this method there is also certain defect, this kind of sealing means belong to side seal mode, because smoke exhaust pipe is variable
Shape is limited plus the upset space in it, and certain gap must be left between baffle plate and the passage of smoke exhaust pipe,
Otherwise easily be stuck, such structures shape its cannot down-draught-proof completely, still have some cold airs and fall
Pour into inside gas heater, cause water tank to be damaged by frost.
The content of the invention
One purpose of first aspect present invention is intended to overcome at least one defect of existing gas heater,

One of first aspect present invention is further objective is that will make flow of flue gas uniform, raising produces hot water
Efficiency.
One purpose of second aspect present invention is to provide for a kind of gas heater with above-mentioned exhaust fume collecting hood.
According to the first aspect of the invention, the invention provides a kind of exhaust fume collecting hood, it includes:
Housing with flue gas flow export, it defines downward opening flue gas accumulation chamber;
Distance piece with rake, in the flue gas accumulation chamber, is configured to the flue gas accumulation chamber
It is separated into the first cavity and the second cavity for connecting the flue gas flow export for connecting the opening;The inclination
Towards first cavity, the upper surface of the rake is towards second cavity for the lower surface in portion;And institute
State and offered on rake at least one intercommunicating pore;With
At least one baffle plate, each described baffle plate is located in second cavity and its upper end is rotatably mounted
In the distance piece or the housing, it is configured to block a connection in the presence of its own gravity
Hole, and each described baffle plate can by from it is described opening opened into the flue gas top of first cavity so that flue gas
Enter second cavity via at least one intercommunicating pore, finally flowed out from the flue gas flow export.
Alternatively, the vertical central axial line weight of the vertical central axial line of the distance piece and the flue gas accumulation chamber
Close.
Alternatively, the rake of the distance piece is two hang plates, and each described hang plate is parallel to described
The width of flue gas accumulation chamber, and the top edge being connected with the inner wall sealing of the housing from it downwards and to
Direction near the vertical central axial line of the flue gas accumulation chamber extends to its lower edge;And
There are one or more described intercommunicating pores on each described hang plate.
Alternatively, the distance piece also includes:
Two connecting plates, each described connecting plate parallel to the flue gas accumulation chamber length direction, and set
Between two lateral edges of the hang plate homonymy;With
Base plate, it is horizontally extending, it is arranged on the following of two hang plates and two connecting plates
Between edge.
Alternatively, the rake of the distance piece is cylindrical in shape, and is connected with the inner wall sealing of the housing from it
Direction of the top edge downwards and to the vertical central axial line near the flue gas accumulation chamber extends to its lower edge.
Alternatively, the cross-sectional profiles of the rake are circular or regular polygon;And the number of the intercommunicating pore
It is multiple to measure, and the circumferential direction along the distance piece is uniform.
Alternatively, vertically extend convex to second cavity from the mouth edge of intercommunicating pore each described
Rib, the lower surface of each baffle plate fin corresponding to when a corresponding intercommunicating pore is blocked
Distal end faces contact against.
Alternatively, each described baffle plate includes:
Occlusion part, is configured to block a corresponding intercommunicating pore, and its lower surface is corresponding described in closure one
Upper surface during intercommunicating pore with the rake is parallel;
