Because receive the restriction of auxiliary air, traditional distributor has received certain limitation aspect performance boost.For the distributor of being furnished with round fire hole outer fire cover; The quantity of outside fire hole and fire hole area are set according to input power and fire lid outside dimension, if the fire hole spacing is too small, will produce the flame adhesion phenomenon; The contact-making surface of flame and auxiliary air reduces; Cause that harmful components increase in the flue gas, suitably increase fire lid external diameter the fire hole spacing is increased, but the thermal efficiency is descended.For the distributor of being furnished with finedraw fire hole outer fire cover, though have the higher thermal efficiency,, under powerful situation, be prone to imperfect combustion takes place because the stage casing of finedraw fire hole lacks auxiliary air, generally be applicable to lower-powered occasion.
The utility model content
The purpose of the utility model is to provide a kind of auxiliary air enhancement mode distributor.The utility model has solved traditional distributor because of there being the problem that the auxiliary air undersupply is restricted and cause the input power and the thermal efficiency to be difficult to promote; On distributor, set up and to have strengthened the fire hole air duct of auxiliary air on every side; Make the contact condition of flame and auxiliary air that obvious improvement arranged; Under the condition of identical outer fire cover outside dimension, can obtain the bigger input power and the higher thermal efficiency, improved the stability of kitchen range combustibility and burning.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of auxiliary air enhancement mode distributor comprises distributor base, distributor loam cake, external ring fire cover, interior ring fire lid; Described distributor base and distributor loam cake are connected, and are placed with external ring fire cover on the distributor base, cover on the distributor to be placed with interior ring fire lid; Be evenly equipped with the finedraw fire hole on the described external ring fire cover, offer three the first air flue holes and the second air flue hole on the described distributor base, corresponding with it position also offers three first air flue hole exits on the described external ring fire cover; Cover corresponding with it position on the described distributor and also offer three second air flue hole exits; The described first air flue hole exits divides growth finedraw fire hole and short finedraw fire hole with the finedraw fire hole on the external ring fire cover.
Described three first air flue holes are evenly to distribute, and described three second air flue holes also are evenly to distribute.
Said short finedraw fire hole comprises the second short finedraw fire hole that is positioned at the first inboard short finedraw fire hole of the first air flue hole exits and is positioned at the first air flue hole exits outside.
The beneficial effect of the utility model is: the utility model distributor is an auxiliary air undersupply of avoiding existing distributor to exist, and when causing burning, flame produces malcombustions such as connecting flame, Huang Huo, finally causes imperfect combustion, discharges harmful object.The segmented combustion technology that proposes through distributor base appropriate design is become three air flue modes, solves air-flow and is diverted to each zone uniformly, avoids air flue place air-flow excessive, makes flame leave flame.External ring fire cover adopts segmented design (design of long finedraw fire hole and short finedraw fire hole, short finedraw fire hole is distributed in the both sides of three air flue outlets), and the benefit that has increased auxiliary air is gone into, and makes flame combustion more abundant.Performance indications are higher.The utlity model has following advantage: 1. air-flow distributional stability; 2. sufficient combustion reduces discharge of harmful gases; 3. the thermal efficiency is high; 4. be easy to obtain bigger input power; 5. compact conformation is convenient to I&M.
