Detailed Description
The invention will now be more fully described by way of example only and with reference to the accompanying drawings, but the invention is not thereby limited to the scope of the examples described.
Example 1
As shown in fig. 1, embodiment 1 of the present invention discloses a kitchen range burner 8, comprising a burner structure. The burner structure comprises an inner ring fire cover 1, thermocouples 2 and anti-blocking cap edges, wherein the anti-blocking cap edges are arranged on the inner ring fire cover 1, the anti-blocking cap edges are located above the thermocouples 2, main fire holes 4 and fire protection holes 5 are formed in the inner ring fire cover 1, the diameters of the fire protection holes 5 are D1, the diameters of the main fire holes 4 are D2, D2 is larger than D1, the horizontal plane where the main fire holes 4 are located is located below the horizontal plane where the end parts of the thermocouples 2 are located, the horizontal distance between the axes of the thermocouples 2 and the wall surfaces where the air outlets of the main fire holes 4 are located is L, the radius of the anti-blocking cap edges 3 is R1, the horizontal distance between the air inlets of the main fire holes 4 and the air outlets of the main fire holes 4 is R3, and the diameters of the thermocouples 2 are D1, and D1/2 are smaller than or equal to L is smaller than or equal to R1-R3.
Specifically, the distance in the horizontal direction from the axis of the thermocouple 2 to the center of the inner ring fire cover 1 is R2.
Most of the existing stove burner 8 is provided with a thermocouple 2 type flameout protection device, a plurality of small holes are designed on the inner ring fire cover 1 at positions opposite to the temperature sensing head of the thermocouple 2 to serve as the flame protection holes 5, the electromotive force required by electromagnetic valve suction can be maintained by thermal potential generated by temperature sensing of the head of the thermocouple 2, the temperature of the head of the thermocouple 2 cannot exceed 650 ℃, the material temperature resistance requirement of the end part of the thermocouple 2 is met, the aperture of the flame protection holes 5 opposite to the thermocouple 2 is usually designed to be smaller, after the stove burner is used for a period of time, the flame protection holes 5 are extremely easy to be blocked by greasy dirt or spillover liquid, and the like, so that when a user is in a state of being flameout, or when flame stabilizing small holes are blocked, flames appear, the flames cannot burn the head of the thermocouple 2, and thus the fire is not protected, namely the flame is flameout, and the use experience of the user is affected. A common method for easily blocking the fire cover hole by oil stains is to design an anti-blocking cap rim 3 above the fire protection hole 5. In order to solve the problem that the fire protection hole 5 is easy to block, a cap edge structure is designed above the fire hole of the inner ring fire cover 1, but the anti-blocking cap edge 3 is too small in diameter and poor in anti-overflow effect, and the problem that the fire hole burns to the anti-blocking cap edge 3 when the diameter of the anti-blocking cap edge 3 is too large can occur, so that smoke exceeds standard or the inner ring fire cover 1 is burnt to change color and the like. If the anti-blocking cap rim 3 is heightened, the problems that the bottom of the pot is propped against the inner ring fire cover 1 and the like can occur, and the diameter of the existing fire protection hole 5 is smaller, usually horizontally or obliquely upwards, when overflow or greasy dirt exists, under the action of gravity, the overflow or greasy dirt easily flows from the outer side (namely high position) to the inner side (namely low position) of the fire outlet hole of the inner ring fire cover 1, so that the pot is easy to be blocked.
As shown in fig. 1 and 2, by correspondingly setting the position relation of the main fire hole 4 on the inner ring fire cover 1, the position relation of the main fire hole 4 and the thermocouple 2, and the aperture sizes of the main fire hole 4 and the fire protection hole 5, the main fire hole 4 can have the function of fire protection, meanwhile, the main fire hole 4 is used as the fire hole with the largest diameter on the inner ring fire cover 1 to participate in fire protection, and the condition of fire protection can only occur when the main fire hole 4 is almost completely blocked, thereby improving the anti-blocking performance and the fire protection performance of the inner ring fire cover 1; the distance between the thermocouple 2 and the main fire hole 4 is kept to be L, so that the temperature of the head part of the thermocouple 2 is not higher than 650 ℃, the normal use temperature resistant range of the thermocouple 2 is achieved, the service life of the thermocouple 2 is prevented from being influenced, and the thermocouple 2 is prevented from being burnt out; the highest point of the end part of the thermocouple 2 is slightly higher than the point of the central axis of the 2 main fire holes 4 participating in fire protection, when the flame stabilizing small holes are blocked, the flame can still burn to the temperature sensing head part of the thermocouple 2 under the condition that the flame of the main fire holes 4 is lifted off, namely, when the flame stabilizing small holes are completely blocked, the fire can be protected, and finally, the defect that the fire protection performance cannot be improved well in the prior art is overcome.
As shown in FIG. 4, the number of the main fire holes 4 is two, the two main fire holes 4 are distributed on two sides of the thermocouple 2 at intervals, and the included angle between the axes of the two main fire holes 4 is alpha, and alpha is 15 degrees less than or equal to 20 degrees. The two main fire holes 4 participating in fire protection are designed and distributed on the left side and the right side of the temperature sensing head part of the thermocouple 2, are not just opposite, but are arranged in a staggered way to form a certain included angle, and part of flame burns to the thermocouple 2, so that the overhigh temperature of the end part of the thermocouple 2 is avoided, and the service life of the thermocouple 2 is prolonged. If alpha is too large, the heating temperature of the two main fire holes 4 to the end part of the thermocouple 2 is too low, and when the two main fire holes 4 are used for fire protection, the electromotive force is lower than 3.5mV, namely lower than the minimum electromotive force for maintaining the attraction of the electromagnetic valve.
The included angle between the axis of any main fire hole 4 and the horizontal plane isThe included angle between the connecting line of any main fire hole 4 and the anti-blocking cap edge 3 and the horizontal plane is beta and +.>The angle is set so that the long line of the upper edge of the diameter of any main fire hole 4 does not interfere with the cap edge of the inner ring fire cover 1, thereby improving the fire protection performance.
This arrangement can improve fire protection performance.
The diameters of the two main fire holes 4 are D2, and D2 and alpha are in direct proportion to nonlinear change. D2 is proportional to α, and the angle α is also reduced when D2 is relatively small, otherwise the main fire hole 4 may not burn to the thermocouple 2 or the electromotive force to the thermocouple 2 is insufficient. The main fire hole 4 which is deviated left relative to the thermocouple 2 is at an angle alpha/2, and the main fire hole 4 which is deviated right is at an angle alpha/2.
The plurality of fire protection holes 5 extend from the outer wall surface of the inner ring fire cover 1 to the inner wall surface of the inner ring fire cover 1 in the horizontal direction. The fire protection hole 5 penetrates the inner ring fire cover 1, so that the flame can smoothly gush up to the thermocouple 2. Between the included angle middle surfaces of the two main fire holes 4 participating in fire protection, a horizontal fire protection hole 5 with the aperture of D1 is designed at the same height position of the lower row of flame stabilizing holes 6.
Specifically, the burner structure relies on the combined action of flames of two main fire holes 4 and three fire protection holes 5, the fire hole with the largest diameter on the inner ring fire cover 1 is the main fire hole 4, the main fire hole 4 participates in fire protection, and fire protection can not be realized only when the main fire hole 4 is almost completely blocked, and the anti-blocking performance is improved, so that the fire protection performance is improved; in a worse case, such as a case that the two main fire holes 4 are partially separated, since the lifted flame is obliquely upward along the air outlet direction, that is, the flames of the two main fire holes 4 can still burn to the head of the thermocouple 2 when lifted flame, the fire protection performance under the lifted flame condition is improved.
As shown in fig. 2, the intersection point of the axis of the thermocouple 2 and the axes of the two adjacent main fire holes 4 is a point a, the end of the thermocouple 2 is a point B, and the distance between the point B and the point a in the height direction is h,1/3×d2 is equal to or less than h is equal to or less than 1/2×d2. The position relation between the diameter of the main fire hole 4 and the thermocouple is set, so that the fire protection performance is improved, the head temperature of the thermocouple 2 is prevented from being too high, and the fire protection efficiency of the thermocouple 2 is further improved. The point B is higher than the point A, when the fire hole 5 is blocked, the electromagnetic force generated by the head of the thermocouple 2 can still maintain the electromagnetic valve to be attracted by depending on the flame temperature of the two main fire holes 4, so that the fire can be kept. When the horizontal distance L between the axis of the thermocouple 2 and the wall surface where the air outlets of the main fire holes 4 are positioned is the maximum value, the end B point of the thermocouple 2 is ensured to be below the anti-blocking cap edge 3 of the inner ring fire cover 1, and whether the side is easy to drop by overflowed liquid or the like to cause flameout is avoided.
As shown in fig. 1, the burner structure further includes a plurality of flame stabilizing holes 6 and flame stabilizing annular slits 7, the flame stabilizing holes 6 are arranged on the inner ring fire cover 1 at intervals, the flame stabilizing annular slits 7 are circumferentially arranged at the lower end of the inner ring fire cover 1, and the main fire hole 4 and the flame protecting hole 5 are located above the flame stabilizing annular slits 7. The flame stabilizing holes 6 and the lower flame stabilizing circumferential seams 7 play a role in stabilizing flames of the upper main fire holes 4, so that the main fire holes 4 are prevented from being separated from flames, and meanwhile, the electromotive force generated by the holes on the end part B of the thermocouple mainly plays a role in improving the electromotive force allowance. The fire protection hole 5 and the lower flame stabilizing circumferential seam 7 play a role in stabilizing the flame of the upper main fire hole 4, and prevent the main fire hole 4 from being away from the flame.
In a preferred embodiment, the flame stabilizing structure of the inner ring flame cover 1 comprises a lower flame stabilizing hole 6+flame stabilizing circumferential seam 7 and an upper flame stabilizing hole 6 below the anti-blocking cap rim 3, so that the flame stabilizing performance is improved, and the problem of flame retention caused by flame separation is solved; the anti-blocking cap edge 3 structure of the inner ring fire cover 1 plays a certain role in shielding greasy dirt and spillover, and can reduce the probability of blocking the fire protection hole 5.
Example 2
The same parts as those in example 1 in example 2 will not be repeated, and only the differences will be explained.
As shown in fig. 3, a plurality of fire protection holes 5 extend obliquely upward inward from the outer wall surface of the inner ring fire cover 1 to the inner wall surface of the inner ring fire cover 1. The fire protection hole 5 is communicated with the inner ring fire cover 1, and meanwhile, the fire protection hole 5 is obliquely inwards and upwards extended to the inner wall surface of the inner ring fire cover 1 from the outer wall surface of the inner ring fire cover 1, so that when oil stains or overflows exist, the oil stains or the overflows cannot enter the fire protection hole 5 under the action of gravity, the fire protection hole 5 cannot be blocked, and the problem that the electromotive force allowance is insufficient when the main fire hole 4 and the main fire hole 4 are blocked due to the fact that the fire protection hole 5 is blocked is solved.
In a preferred embodiment, in example 2, the air outlet angle of the fire protection hole 5 with the aperture of D1 is inclined downward from inside to outside, when oil stain or spilled liquid is present, the oil stain or spilled liquid will not enter the fire hole under the action of gravity, so as to ensure that the fire protection hole 5 will not be blocked, thereby improving the problem of non-retention caused by the blocking of the fire protection hole 5; the fire protection hole 5 plays a role in stabilizing the flame of the upper main fire hole 4 and playing a role in protecting the thermocouple 2, and the electromotive force generated by the fire protection hole 5 on the corresponding part of the thermocouple 2 mainly plays a role in improving the electromotive force allowance, and meanwhile, the situation that the fire protection hole 5 is blocked due to flame separation is improved.
Specifically, the intersection point of the axis of the extending direction of the fire protection hole 5 and the axis of the thermocouple 2 is point C, and the distance between point B and point C is H, where H < 5mm.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and the scope of the invention is defined by the appended claims.
