Background technique
Wall-hung boiler is also known as gas-heating water heater, is that one kind heats water by burner, realizes heating and health
The household electrical appliance of hot water two purpose function.
Currently, wall-hung boiler, when using hot water in summer, when supply water temperature is raised to 30 degree or so, wall-hung boiler is adjusting control
When the proportioning valve of air inlet size to minimum gas inlet amount heats water, still leaving water temperature can be made excessively high, user's reflection
Summer is too high using hot water temperature, affects the comfort of user's shower.
Meanwhile wall-hung boiler, when shutting down starting, the proportioning valve of control air inlet size can fully open, and moment enters combustion chamber
Interior gas quantity is larger, and gas-heating water heater is lighted a fire under the full load of normal operating conditions, at this time due to igniting when
Air inflow it is larger, be easy to happen deflagration phenomenon.Especially in the lower situation of winter conditions temperature, wall-hung boiler cold start
When be easier occur detonation, when serious it may also happen that explosion, lead to the generation of accident, the life and property to user cause to damage
It loses.
Summary of the invention
The main purpose of the present invention is to provide a kind of burner and with its household electrical appliance, to solve in the prior art
Water temperature over-high, user experience bad problem are be easy to cause when heating to water.
To achieve the above object, the present invention provides a kind of burners, comprising:
Main body；

39 and fire row 32 arrangement, while equally distributed nozzle 33 may make burner 6 can be uniformly real in the size of venting cavity
The adjusting of existing 33 quantity of nozzle, that is to say, that the big minor adjustment more steady and continuous of wall-hung boiler load further improves use
Family experience.
With further reference to Fig. 2, the burner 6 in this implementation further includes the guide rail 36 being arranged on point gas part 39, guide rail 36
Extending direction it is consistent with the length direction of gas part 39 is divided, isolation block piece 37 be slidably mounted on guide rail 36, and then be isolated
Block piece 37 passes through the guidance of guide rail 36 during the motion, and motion process is more smooth, and wall-hung boiler payload is adjusted more
Add steadily, user experience is more preferably.
To dynamic clamping head and quiet clamping head mobile for realizing isolation block piece 37 in this present embodiment, dynamic clamping head and quiet clamping head in the present embodiment
It is arranged in dividing 39 adjusting cavity of gas part, so that dynamic clamping head and quiet clamping head can be separated at intervals with air inlet pipe 35 and combustion gas, dynamic clamping head and quiet clamping head fortune
Safety during row is more preferably.Wherein, the both ends of dynamic clamping head and quiet clamping head are fixed with the inner wall that block piece 37 and adjusting cavity is isolated respectively
Connection.
Specifically, the dynamic clamping head and quiet clamping head in the present embodiment is to be mounted on a point reset spring 38 for 39 side of gas part, by multiple
The movement of control isolation block piece 37, adjusts the size of venting cavity under the collective effect of position spring 38 and the expansive force in adjusting cavity,
And then the quantity of controllable main jet 33, realize the adjusting of the different combustion powers of burner 6.
With further reference to Fig. 2, the main body in the present embodiment includes that 40 He of left installation bracket of point 39 two sides of gas part is arranged in
Right mounting bracket 34 divides gas part 39 by left installation bracket 40 and right mounting bracket 34 is mountable guarantees in the main body of wall-hung boiler
Reliability when burner 6 works.
Preferably, isolation block piece 37 sealing in the present embodiment acts against the inner wall of point air cavity, such as can keep off in isolation
Increase sealing ring between part 37 and the inner wall for dividing air cavity, may make isolation block piece 37 reliably to seal adjusting cavity and venting cavity, fire
Reliability in 6 operational process of burner is more preferably.
The present embodiment additionally provides a kind of household electrical appliance, including burner 6, and burner 6 is burner 6 as described above,
And then advantage possessed by burner 6 in the present embodiment, the household electrical appliance in the present embodiment should also have, details are not described herein.
Wherein, the household electrical appliance in the present embodiment are the household electrical appliance that wall-hung boiler, gas-cooker etc. use burner 6.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
