Description
Technical field
The utility model relates to a kind of gas-cooker, specifically relates to a kind of Blowed premixed domestic gas stove device.
Background technology
Along with the use of natural gas is popularized gradually in each city of China, various household gas utensils are increasing.At present, domestic household gas utensils adopt the partly-premixed combustion system of injection type mostly, and its main feature is the partial air needed for combustion gas injection burns, there is incomplete combustion phenomenon, thus the thermal efficiency is not high, and in combustion product, pollutant levels are higher, reduces indoor air quality.Although the fully premixed combustion system that external household cooker generally adopts has some superiority in the thermal efficiency and discharge of poisonous waste, its thermic load is less, is difficult to meet China's culinary art requirement.
Utility model content
The purpose of this utility model is: provide the modified form that a kind of sufficient combustion, the thermal efficiency are high Blowed premixed household gas utensils.
The technical solution of the utility model is: the Blowed premixed household gas utensils of a kind of modified form, comprise burner, the top of burner is provided with fire hole, the bottom of burner is connected with injector, at the arrival end of injector, gas nozzle is installed, gas nozzle is laid with primary air air admission hole, also premixer is provided with between described burner and injector, the distribution plenum of annular is arranged with outside premixer, this distribution plenum is connected with air blast by the induced duct that outer wall is arranged, the auxiliary air air admission hole be communicated with described premixer is offered around even circumferential on the inwall of this annular distribution plenum.
Described burner is single fire-hole burning apparatus.
Described air blast is speed-changing draught fan.
Modified form of the present utility model Blowed premixed household gas range lamps structure is simple, easy to use, it lays the difficulty that primary air air admission hole can reduce primary air supply on gas nozzle, fundamentally can solve burner flare and occur yellow flame and insufficient problem causing carbonomonoxide concentration higher of burning, between burner and injector, premixer is set, combustion gas can be mixed before entering combustion chamber fire hole completely with air, effective lifting mixed effect, there is burning completely, burning velocity is fast, the feature that flame temperature is high, efficiently solve prior art Problems existing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Blowed premixed household gas utensils of the utility model modified form.
Detailed description of the invention
The specific embodiment of the Blowed premixed household gas utensils of modified form of the present utility model as shown in Figure 1, it comprises burner 2, injector 1 is connected with in the bottom of burner 2, be provided with gas nozzle 3 at the arrival end of injector 1, on gas nozzle 3, even circumferential is laid with primary air air admission hole 4.Premixer 7 is also provided with between burner 2 and injector 1, the distribution plenum 5 of annular is arranged with outside premixer 7, this distribution plenum 5 is connected with air blast (depending on not going out in figure) by the aid distributing pipe 8 that outer wall is arranged, and offers around even circumferential on the inwall of this annular distribution plenum 5 the auxiliary air air admission hole 6 be communicated with premixer 7.Wherein, air blast adopts speed-changing draught fan, and it can control the auxiliary air air inflow in premixer by control rotation speed of fan, thus can control to match with gas flow, meets the real-time Air Quantity Required of burner when kitchen range thermic load changes.Burner of the present utility model adopts single fire-hole burning apparatus, makes this gas kitchen ranges firepower calorific intensity that is more concentrated, fire hole higher.
Primary air needed for the Blowed premixed household gas utensils burning of modified form of the present utility model is provided by the primary air air admission hole that gas nozzle is offered, it not only can reduce the difficulty of primary air supply, and fundamentally can solve the yellow flame of burner flare and the higher problem of insufficient carbonomonoxide concentration caused of burning, simultaneously, after selecting this nozzle, the primary air ratio value calculated by present traditional injector computing formula and experiment value have larger overgauge, therefore according in the computational process of primary air ratio determination injector size, ratio result of calculation eductor design size can got is a little bit smaller, thus can save a large amount of kitchen range and produce material, thus reduce the production cost of kitchen range.Premixer and annular distribution plenum are set between burner and injector, auxiliary air needed for burning enters precombustion chamber in the mode of annular and completes the transverse and longitudinal premix with combustion gas, make combustion gas more even with mixing of air, thus during the work of these kitchen range, burning is more complete, effectively improve the thermal efficiency of kitchen range, have that burning velocity is fast, flame temperature high.Modified form of the present utility model Blowed premixed household gas range lamps structure is simple, easy to use, the thermal efficiency is high, effectively reduce the discharge of harmful substances from flue gases, be applicable to choosing and use of household gas range, be easy to promotion and implementation, there is good economic benefit.
