Abstract
The invention discloses a gas stove cooker supporting device assembled with permanent magnet, belonging to the technical field of household appliances. The NdFeB permanent magnet of the device is assembled on the stand column support of a cast iron base, and the outside is covered by temperature-resistance ceramics; the magnet is divided into four pieces to be aslant and evenly arranged so as to generate a gradient magnetic field in the supporting device. According to the characteristic that oxygen is continuously consumed to generate oxygen concentration gradient in different zones in the gas burning process, the gradient magnetic field generated by the permanent magnet drives fresh air to continuously flow to flame surface so as to supplement oxygen needed by gas combustion, thus strengthening gas combustion process, and overcoming the shortages of insufficient combustion and low combustion efficiency of the existing gas stove.
Description
Technical field
The invention belongs to the home electric technical field.Be particularly related to the gradient magnetic that utilizes permanent magnet to produce and accelerate fresh air flowing to gas kitchen range flame, thereby overcome the defective that existing gas-cooker burning is insufficient, carbonomonoxide concentration is high, improve a kind of household gas range cooker supporting device that is equipped with permanent magnet of fuel gas buring efficient.
Background technology
Gas-cooker refers to carry out with gaseous fuels such as liquefied petroleum gas, artificial coal gas, natural gases the kitchen utensils of direct combustion heating.The air intake mode of gas-cooker mainly contains three kinds of upper air inlet, lower air intake and side air intakes in the market.Lower air intake type relies on larger cabinet slit to come the required auxiliary air of aftercombustion, the combustion gas of leaking when discharging igniting simultaneously.Because the domestic user does not have the custom of cabinet perforate, cause the gas-cooker burning insufficient, produce yellow flame, carbonomonoxide concentration is high.The upper air inlet type has improved the shortcoming of time air intake type, and burner is raised above table top, and air enters from the slit of burner and cooker.The rising because this formation high-temperature region, position during fuel gas buring, cold air are heated is difficult for entering burner, and auxiliary air can not get effectively replenishing, and still can't resolve the higher problem of Huang Yan and carbonomonoxide concentration, and the thermal efficiency is lower.Side air intake type is installed air-intaker in panel relative low temperature district, when the air in the housing reduces the formation negative pressure, cold air can be along the entrance suction casing of air-intaker, and required auxiliary air when sufficient primary air and burning are provided has solved burn yellow flame and the high problem of carbonomonoxide concentration.Embedded glass faceplate gas cooker tool mostly is greatly front two kinds of forms on the market at present, is prone to the phenomenons such as burning is insufficient, Huang Yan.Because air is the paramagnetism medium, can be subject to the attraction in magnetic field, if therefore the space between burner and cooker makes up a gradient magnetic, can promote flowing of air, improve the fuel gas buring situation.
Summary of the invention
The objective of the invention is the defective for existing gas kitchen ranges, proposing a kind of gradient magnetic that produces by permanent magnet provides a kind of household gas range cooker supporting device that is equipped with permanent magnet of the required sufficient air of fuel gas buring, it is characterized in that, on ring-like cast iron base column by bolt or inlay and be connected and fixed Nd-Fe-B permanent magnet, permanent magnet divides four evenly to be in tilted layout, outward opening, its magnetic pole is arranged by the mode of N, S, N, S
The outside of described Nd-Fe-B permanent magnet coats the heatproof ceramic material.
Described permanent magnet is fixed between burner and the cooker, the space of permanent magnet between burner and cooker produces gradient magnetic, direction is pointed to the bracing or strutting arrangement central area by the outside, because oxygen is the paramagnetism medium, in gradient magnetic, can be subject to the attraction in magnetic field, namely when it is in the gradient magnetic, can flow to the high zone of magnetic field intensity, according to the electromagnetism correlation theory, be in the magnetic field force that the air in the gradient magnetic is subject to and be:
Wherein, μ
0Be space permeability (4 π * 10
-7H/m), H is magnetic field intensity,
Be magnetic field gradient.
With
Be respectively the aerial percent by volume of oxygen magnetic susceptibility and oxygen.
In the fuel gas buring process, oxygen is constantly consumed, therefore near the oxygen concentration the combustion flame district is low, and it is high away from the oxygen concentration of flame zone, cause near the flame zone, be that the magnetic field force that is subject to of the air of cooker supporting device inside is little, and the magnetic field force that the cooker supporting device peripheral air is subject to is large, under unbalanced magnetic field force effect, air flows to the high zone of magnetic field intensity, namely by the outside in cooker supporting device and space that cooker forms to the spatial flow between the two, thereby provide fuel gas buring required sufficient air, promote combustion gas fully to burn, improve the combustion position of gas-cooker.
The invention has the beneficial effects as follows that the space of permanent magnet between burner and cooker produces gradient magnetic, under unbalanced magnetic field force effect, air flows to the high zone of magnetic field intensity, thereby the air of the required abundance of fuel gas buring is provided, and improves the combustion efficiency of gas-cooker.
Description of drawings
Fig. 1 is that the gas stove cooker supporting device structure and the fuel gas buring process Air that are equipped with permanent magnet are subjected to the force direction schematic diagram.
The specific embodiment
The present invention proposes a kind of household gas range cooker supporting device that is equipped with permanent magnet, to promote Air Flow, improves the fuel gas buring situation.In the gas stove cooker supporting device structural representation that is equipped with permanent magnet shown in Figure 1, the ring-like base 1 of cast iron is positioned on the burner 5 at gas kitchen range panel center, on cast iron upright column 2, be connected and fixed Sintered Nd-Fe-B Permanent 3 by bolt or mosaic mode, permanent magnet divides four evenly to distribute, and be and be in tilted layout, opening is outwardly.Its magnetic pole is staggered by the order of N, S, N, S.Coat heatproof ceramic material 4 in permanent magnet 3 outsides.
The described gas stove cooker supporting device that is equipped with permanent magnet, permanent magnet are and are in tilted layout, and can produce gradient magnetic at the bracing or strutting arrangement zone line.Because the symmetry that permanent magnet is arranged, magnetic field intensity is 0 on the central axis of bracing or strutting arrangement, direction from center to periphery, and magnetic field intensity increases gradually.Top by bracing or strutting arrangement is downward, and magnetic field intensity also is increase trend.As seen, the Changing Pattern of magnetic field intensity is for increasing from inside to outside, and from top to bottom increase, so the direction of magnetic field gradient is outward-dipping sensing bottom, and this also is air magnetic field force induced f in gradient magnetic
mDirection, as shown in Figure 1.
In the fuel gas buring process, oxygenous quilt constantly consumes near the air the flame, and oxygen concentration is low, and the suffered magnetic field force of air is little.And away from the zone of flame, content of oxygen in air is high, and the suffered magnetic field force of air is large.Under this imbalance magnetic field force effect, fresh air will be endlessly by away from the space outerpace of flame to the flame Flow Structure Nearby, the fresh air that is consumed to replenish fuel gas buring, thus promote combustion gas fully to burn, improve the combustion efficiency of gas-cooker.
