Description
Technical field
The present invention relates to the technical field of electrical appliances manufacturing more particularly to a kind of gas heaters with decrease of noise functions.
Background technique
Being forced to exhaust gas heater is a kind of common gas heater, and complete machine closing, inside forms one
Cavity, air inlet and smoke evacuation are realized by the double-deck smoke pipe.The whole cavity and smoke pipe system of forced-ventilated gas water heater form one
A closed flow, and the closed flow intrinsic frequency is close to the intrinsic frequency of smoke pipe system.However, due to the combustion in enclosure space
It burns, easily generation combustion oscillation, combustion oscillation can bring disturbance to the air in confined space；If the frequency of combustion oscillation is close
The intrinsic frequency of flow passage system easily induces strong combustion oscillation phenomenon, shows as operation panel before gas heater
High vibration, or even dead fire is easily caused, and bring the danger such as gas leakage.
The mechanism that the combustion oscillation generates is: since vigorous combustion causes air to expand rapidly, and the air expanded is to wind
Machine air duct can generate negative pressure, cause air inlet insufficient, oxygen content decline；Then, combustion heat release also declines rapidly, and air cooling-down is received
Contracting, to ducting system generate normal pressure so that volume of air supply increase, burning again start acutely, cause air to expand, machine internal cavity and
The intrinsic frequency and combustion oscillation frequency of ducting system very close to when, system combustion state can be caused repeatedly, i.e. the above process
Circulation occurs, to induce combustion oscillation.
For being forced to exhaust gas heater, water heater cavity itself is closed, it would therefore be highly desirable to invent one
Kind, which can be avoided, occurs above-mentioned combustion oscillation phenomenon and because of the gas heater of its noise problem caused.
Summary of the invention
In order to solve the above-mentioned technical problem, it the invention reside in a kind of gas heater is provided, is easily sent out with solving the prior art
Raw combustion oscillation phenomenon, and it is big because of the noise that it causes the problems such as.
In view of the above technical problems, the present invention proposes a kind of gas heater comprising: shell, combustion chamber, draws smoke pipe
Flow device and blower.There is sealing cavity in shell, offer draining hole on the shell；Smoke pipe from the sealing cavity to
It is extended outside the shell comprising inlet channel and exhaust passage；Combustion chamber is set in the sealing cavity, the combustion
Burning room is connected to the exhaust passage to be expelled to outside the shell with the exhaust gas to be burnt；Drainage device is set to the shell
Draining hole, and it is fixed on the housing；The drainage device can drain the air outside the shell through described in its inflow
In the sealing cavity of shell, and the intracorporal gas of the shell can be stopped to flow out to outside the shell through it simultaneously；Blower is placed in
In the sealing cavity, the blower via the inlet channel and drainage device will enter the air delivery of sealing cavity
In to the combustion chamber.
In a preferred approach, the draining hole on the shell is disposed in proximity to the position of the blower.
In a preferred approach, the drainage device includes: the breather cheek valve with one-way ventilating；The breather cheek valve
Inlet end be arranged outwardly relative to the shell；The breather cheek valve, which has, to be opened threshold value and closes threshold value, when the shell
When intracorporal pressure reaches the unlatching threshold value, the breather cheek valve can automatically turn on and introduce external air into the shell
It is interior；When the intracorporal pressure of the shell reaches the closing threshold value, the breather cheek valve be can be automatically closed and stop will be extraneous
Air introduces in the shell.
In a preferred approach, the drainage device further include: mounting plate, the breather cheek valve are pacified by the mounting plate
Loaded on the draining hole；The mounting plate along the breather cheek valve circumferentially extending be arranged, the outer edge of the mounting plate with
The draining hole adaptation.
In a preferred approach, the outer rim of the mounting plate is equipped with sealed frame.
In a preferred approach, the mounting plate in the shell in being mounted on the draining hole.
In a preferred approach, the shell is in rectangular parallelepiped structure comprising: outer panels, backplate, and be connected to described
Two opposite side panels between outer panels and backplate；The blower is located at the intracorporal lower part of shell and close to a side panel
Setting, the draining hole are provided close on the side panel of the blower.
In a preferred approach, the smoke pipe is the double-deck smoke pipe comprising: it interior conduit and is sheathed on outer outside said inner tube road
Pipeline, the channel in said inner tube road constitute the exhaust passage；Described in channel between the Outer Tube and interior conduit is constituted
Inlet channel, the inlet channel are connected to air and the sealing cavity outside the shell.
Compared with prior art, the invention has the following advantages: gas heater of the invention passes through setting drainage
Device can also flow into close so that the air outside shell can either be delivered in sealing cavity from inlet channel through drainage device
It seals in cavity, the amount of supplied air in fan air channel should be increased by the air that drainage device flows into, and be mentioned to be continuously burning
For sufficient oxygen, effectively inhibit the generation of combustion oscillation phenomenon, while playing Noise Reduction.Simultaneously as drainage device has
There is unidirectional gas circulating function, the intracorporal gas of shell will not circulate to outside shell from drainage device, avoid due to gas leakage
Pollute indoor environment, and other dangerous problems because of gas leakage generation.
