Abstract
The utility model discloses a tuyere adjusting structure for a direct-injection burner. The burner comprises a furnace end provided with direct-injection nozzles; and the direct-injection nozzles are connected with air injection tubes. The tuyere adjusting structure has the structural characteristics that the walls of the air injection tubes are provided with tuyeres; and air quantity adjusting sheets are arranged at the tuyeres in a vertical movement mode, and control the tuyere shielding degrees through vertical movement, so that gas and air are mixed and the gas is fully combusted. The tuyere adjusting structure is simple and reasonable in structure, high in adjusting accuracy, convenient and safe to operate, long in service life and wide in application range, and improves the combustion ratio of the gas.
Description
Technical field
The utility model relates to a kind of gas-cooker and uses the direct injection combustion device, particularly a kind of air port adjustment structure of direct injection combustion device.
Background technology
The air port operated by rotary motion of combustion gas and air mixing preparation is on the Gas Pipe of gas-cooker control valve in the existing gas-cooker, and there are 2 deficiencies in it: 1, the control of the unlimited amount in air port is to have level to regulate, and air distribution is not accurate, causes combustion rate low; 2, because the air port is positioned near gas-cooker panel below and the control valve,, will damage gas-cooker panel, control valve etc. easily in case tempering phenomenon occurs.
The burner assembly device that Chinese patent ZL200820099705.3 discloses a kind of gas-cooker on June 13rd, 2009; Comprise two air chamber burners, accurate air distribution dosing hole spare, outside induction tunnel and center induction tunnel; The distributor loam cake; The distributor lower cover connects the inner ring of said distributor loam cake and said distributor lower cover, and its key is that said distributor loam cake is provided with the burning guiding gutter.This structure overcomes above-mentioned the 2nd deficiency, but the deficiency that exists the air distribution amount not regulate haves much room for improvement.
The utility model content
The purpose of the utility model aim to provide a kind of simple and reasonable, degree of regulation is high, improve the combustion rate of combustion gas, the air port adjustment structure of easy and safe to operate, long service life, direct injection combustion device applied widely, to overcome weak point of the prior art.
Press the air port adjustment structure of a kind of direct injection combustion device of this purpose design; Said burner comprises the burner that is provided with straight air nozzle, is connected with air jet pipe on the straight air nozzle, and its architectural feature is that said jet wall portion is provided with the air port; The place, air port moves up and down and is provided with the air quantity adjustment sheet; The amount of blocking in air port is controlled,, thereby reach the clean-burning state of combustion gas with the allotment that realizes that combustion gas mixes with air through moving up and down of air quantity adjustment sheet.
Said air quantity adjustment sheet is provided with the flange hole, flange hole and air jet pipe socket.
Said air quantity adjustment sheet is connected with lifting regulating mechanism, and lifting regulating mechanism comprises the screw rod that rotates setting, and the air quantity adjustment sheet is connected with screw flight; Perhaps, be set with nut on the air quantity adjustment sheet, nut is connected with screw flight.Lifting regulating mechanism also can be a rack and pinion drive mechanism etc.
Said burner is fixedly installed on the stove seat, also is provided with bearing on the stove seat and screw rod is rotationally connected.
Said bearing is arranged on the stove seat through bearing block; Screw rod one end and air quantity adjustment sheet join, and the other end stretches out outside the stove seat and is connected with handle.
Said burner set inside outside air chamber and central air chamber; The burner side is provided with two air inlet pipe joints and is communicated with outside air chamber and central air chamber respectively; Burner end face center and periphery are provided with said straight air nozzle, and are communicated with central air chamber and outside air chamber respectively.
Be arranged with outer shroud windburn amount adjustment sheet on the air jet pipe of the corresponding directly air nozzle of said burner outside air chamber institute; Said burner central air chamber be arranged with on the air jet pipe of corresponding straight air nozzle in ring fire air quantity adjustment sheet; Two air quantity adjustment sheets are connected with lifting regulating mechanism respectively.
The utlity model has following advantage:
(1), the air port is arranged on the air jet pipe, avoids tempering that gas-cooker panel and control valve are impacted;
(2), the unlimited amount in air port regulates through the air quantity adjustment sheet that moves up and down, and the moving by lead screw transmission control of air quantity adjustment sheet realized step-less adjustment, control accurately;
(3), because the unlimited amount in air port is regulated accurately, can improve the fuel gas buring rate, in addition, gas-cooker can use different types of burning gases.
