Abstract
The invention discloses an adjustable air amount blower, which comprises a scroll case, an air inlet plate and a wind wheel blade arranged in the scroll case and driven by a motor. The scroll case is provided with an air outlet. An air inlet plate is arranged on the scroll case and is provided with an air inlet. The adjustable air amount blower is characterized in that the air inlet of the air inlet plate is covered by a movable plate which can adjust the size of the air inlet. The invention also discloses a water heater installed with the blower. Compared with the prior art, the adjustable air amount blower has the advantages of simple and reasonable air amount adjusting structure, convenient operation, smaller installation volume, convenient production of components and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of blower fan, relate in particular to a kind of air volume adjustable blower fan, the invention still further relates to the water heater that this blower fan is installed.
Background technique
At present, gas water-heater generally all is provided with the blower fan of combustion-supporting air below the firing chamber, to improve the heat load of burner, but concrete referenced patent number is Chinese utility model patent " domestic gas-fired water heater blower fan the side located structure " (notice of authorization number: CN2411442Y), can also referenced patent number be Chinese utility model patent " burner of the gas water-heater " (notice of authorization number: CN2539933Y) of ZL02226785.9 of ZL9925252.8.
Yet the fan delivery of above-mentioned prior art is fixed, unadjustable, can not be adjusted to realize best proportions of ingredients according to the actual change of combustion gas and air, and intrinsic in some cases air output influences burning easily.
For this reason, the adjustable gas water-heater of air output has appearred, referenced patent number is the Chinese utility model patent of ZL01255832.X " a kind of volume adjusting apparatus that is used for forced-air blast type gas water-heater " (notice of authorization number: CN2498534Y), this patent includes transfers the wind lower plate, transfer wind upper plate and driving mechanism thereof, wherein transfer the wind lower plate and transfer on the wind upper plate and be respectively equipped with several air quantity adjustment holes, transfer the wind lower plate to be fixed on the Fan casing of water heater motor, transfer the end face of wind upper plate to touch with the end face of transferring the wind lower plate, the driving link of driving mechanism is connected with gas valve core, and driven member is connected with transferring the wind upper plate.The air door of air inlet is regulated in the rotation of this patent utilization stopcock, and gas quantity and air output are complementary, and can realize the synchronous proportioning of gas quantity and burning required air quantity.But clearly, this controlling mechanism complex structure is installed loaded down with trivial detailsly, and installation volume is bigger, is further improved.
Summary of the invention
First technical problem to be solved by this invention is that a kind of simple in structure, air volume adjustable blower fan that installation volume is less is provided at above-mentioned prior art present situation.
Second technical problem to be solved by this invention is the water heater that air volume adjustable blower fan is installed, and this water heater has flameholding, gas quantity and the air air output advantage accurately that is complementary.
The present invention solves the technological scheme that above-mentioned first technical problem adopts: a kind of air volume adjustable blower fan, comprise spiral case, air intake plate and be located in the spiral case by motor-driven wind wheel blade, aforementioned spiral case has exhaust outlet, aforementioned air intake plate is located on the aforementioned spiral case and is had intake grill, it is characterized in that the intake grill of described air intake plate is coated with the mobile plate of this intake grill size of can regulate.
The setting of mobile plate is preferably as follows the horizontal adjustment structure: have row's screw near intake grill on the described air intake plate, accordingly, described mobile plate is arranged in the aforesaid screw to realize the adjusting of intake grill size by a screw adjustable ground.Certainly can also adopt rotary regulating structure.
The intake grill of described air intake plate is two and all is eccentric circular ring and symmetry arranges that at interval described screw is then opened on the joint between described two intake grills, and accordingly, described mobile plate is fan-shaped, and the middle part has for screw to be passed and fixing through hole.Regulate accurately, guarantee flameholding.
The present invention solves above-mentioned second technological scheme that technical problem adopted: a kind of water heater that air volume adjustable blower fan is installed, comprise housing, be located at and combustion-supporting air blower and burner arranged in the housing, the corresponding burner setting of the exhaust outlet of blower fan, it is characterized in that the air intake plate of described blower fan faces the front setting of housing, the intake grill of described air intake plate is coated with the mobile plate of this intake grill size of can regulate.When need regulating air quantity, can shed housing, the people from the front-operated mobile plate to obtain best firing effect.
Compared with prior art, the invention has the advantages that: air quantity regulation structure advantages of simple, simple operation, less to existing fan improvement, do not influence original function, and installation volume is also less, used component are convenient for production, and manufacture cost is lower.
