Abstract

A household gas cooker burner whose center and the peripheral edge of the disk of the burning head is provided with a central fuel gas passage and an inner and an outer ring fuel gas passage and three fire covers that respectively cover the corresponding fuel gas passages, which is characterized in that fire-outlet holes are evenly distributed in the outer edge wall of the fire cover on the central fuel gas passage, the inner and outer edge walls of the inner and the outer ring fuel gas passage are respectively provided with the corresponding fire-outlet holes. Because the utility model is provided with three fuel gas passages and the inner and the outer edge walls of the inner and the inner and the outer ring fuel gas passage are respectively provided with fire-outlet holes, when burning five ring-shaped fire circles from big to small are formed, which reduces the central gap, heats the objects evenly, and the flame is strong and improves the heat utilizing factor and heat efficient and is particularly appropriate to the frying and cooking Chinese style dishes.

Description

Burner for household gas range

Technical field

The utility model relates to the burner of burning gases fuel, more specifically refers to a kind of burner for household gas range.

Background technology

At present, gas-cooker has become a kind of indispensable cooking apparatus in Modern Family, and along with improving constantly of people's living standard, for satisfying people's demand, the burner in the household gas range is among the continuous improvement always.Generally only establish inside and outside two pyrospheres on the burning hybrid chamber of burner in the market, so firepower is not prosperous, cook that it is very time-consuming to cook, especially cooking all causes harmful effect owing to the firepower reason to color.In order to increase power, this traditional burner must increase fire hole quantity to strengthen the fire hole area, must add big fire lid external diameter like this, certainly will cause the burner volume huge.The patent No. is the burner that 01238536.0 Chinese patent discloses a kind of combined household gas-cooker, this burner hybrid chamber that will burn is divided into each other that independently burning mixes exocoel and burning mixes inner chamber, assemble as required by these two kinds of different inner chambers, with the firepower of three pyrospheres or the firepower of two pyrospheres, accomplished firepower is controlled and regulated, but this burner can only adopt the firepower of three pyrospheres at the most, intermediate gaps is too big, heat inhomogeneous, and fire output hole all is located at the fire lid outside, the flame utilization rate is not high, and the thermal efficiency is too low.

Summary of the invention

The purpose of this utility model is at the defective and the deficiency of the burner existence of above-mentioned gas-cooker, proposes a kind of burner for household gas range, and is inhomogeneous to solve the gas-cooker heating, the problem that the thermal efficiency is too low.This burner is provided with center blast tube and inner and outer rings blast tube in the disc centre and the periphery of combustion head, three fire lids are covered on respectively on the corresponding blast tube, it is characterized in that being evenly equipped with fire output hole on the periphery wall of the fire lid on the blast tube of center, have corresponding fire output hole on the inside and outside perisporium of interior ring blast tube and outer shroud blast tube.Because the utility model has three blast tubes, and in, in the outer shroud blast tube, have fire output hole on the periphery wall, form descending five annular pyrospheres during burning altogether, the wherein annular pyrosphere that covers of the fire of center blast tube and the annular pyrosphere on the interior ring blast tube internal perisporium, flame weave in when annular pyrosphere on the interior ring blast tube periphery wall and the annular pyrosphere on the outer shroud blast tube internal perisporium burn, reduced intermediate gaps, object is evenly heated, flame is prosperous, heat utilization efficiency, the also corresponding raising of the thermal efficiency, the utility model is suitable for propagandizing hotly and cooking of Chinese style dish especially.

The specific embodiment

As accompanying drawing 1, shown in 2, burner of the present utility model is provided with center blast tube 6 in the disc centre of combustion head 1, on center blast tube 6, be covered with fire lid 7, fire lid 7 is disc, periphery wall at fire lid 7 is evenly equipped with fire output hole 8, in the periphery of combustion head 1 is provided with, outer combustion gas passage 4,2, fire lid 5,3 be covered on respectively in, on the outer combustion gas passage, fire lid 5,3 are annular, in interior ring blast tube 4 and outer shroud blast tube 2, have fire output hole 9 on the periphery wall, 9 ' and fire output hole 10,10 ', when lighting, form and the annular pyrosphere of corresponding five circles of fire output hole.Between center blast tube 6 and the interior ring blast tube 4 and the toroidal cavity between the inner and outer rings blast tube 4,2 form auxiliary air and replenish mouthfuls 11,12, give fire output hole 8,9 and fire output hole 9 ', 10 annular pyrosphere carries out auxiliary air and replenishes, with fire output hole 10 ' the required auxiliary air of annular pyrosphere replenish the extraneous air that directly comes on the free kitchen range top.When combustion gas is chewed burning with certain speed consumption from fire-fighting, by flow velocity itself suck primary air in the combustion gas inlet channel, forms combustion gas and AIR MIXTURES and the passage by separately enter center blast tube 6 with in, outer shroud blast tube 4,2, and the fire output hole on it is lighted, in, the flame of the annular pyrosphere on the outer shroud blast tube internal perisporium forms the centripetal direction burning, the flame of its excess-three annular pyrosphere forms outwards disperses the direction burning, like this, the mutual weave in of flame during the burning of annular pyrosphere, reduced intermediate gaps, object is evenly heated, and flame is prosperous, the also corresponding raising of the heat utilization efficiency and the thermal efficiency.

Claims (1)

1, a kind of burner for household gas range, be provided with center blast tube (6) and inner and outer rings blast tube (4), (2) in the disc centre of combustion head (1) and periphery, fire lid (7), (5), (3) are covered on respectively on blast tube (6), (4), (2), it is characterized in that being evenly equipped with fire output hole (8) on the periphery wall of fire lid (7), have fire output hole (9), (9 ') and fire output hole (10), (10 ') on the inside and outside perisporium of interior ring blast tube (4) and outer shroud blast tube (2).
