Description
[ field of technology ]
The application relates to the field of gas stoves, in particular to a fire cover of a burner for a gas stove, a stove head of the gas stove, the burner comprising the stove head and the gas stove comprising the burner. Wherein, the bottom of the fire cover is inwards sunken to form an air accommodating cavity.
[ background Art ]
For burners of household gas cookers, the slot-shaped fire outlet is generally formed by: is formed by encircling a fire cover with an inclined plane and a plurality of grooves formed on the base of the fire cover. In order for the fire hole to form a specific fire angle, both the bevel and the slot of the fire cover need to be inclined at an angle to the horizontal. In order to form a cavity for receiving the fuel gas, the bevel of the fire cover is attached to one surface on which the grooves are formed, i.e. the bevel of the fire cover and the surface on which the grooves are formed have exactly the same extension direction.
On the one hand, the requirements for the machining tolerance of the inclined surfaces of the fire cover and the inclined angles of the surfaces formed with the grooves are high, otherwise, the inclined surfaces and the surfaces cannot be attached, so that part of fuel gas flows out from a gap to form flame, and the fire cover is burnt and deformed for a long time. In the batch processing process, after the fire cover is clamped on the clamp, the inclined plane with the required angle is processed, and the angle error is easier to generate when the processed inclined plane of the fire cover in the clamping state is in a natural placing state due to elasticity of the workpiece, so that the rejection rate is higher. The same problem exists in the processing of the fire cover base. In addition, the measurement of the angle of the inclined plane is more troublesome, which brings problems to the material inspection of mass production, and the quality is ensured, so that the cost is obviously increased.
On the other hand, the burner manufactured by the method has the fire hole with an upward inclination angle of 25 degrees relative to the horizontal plane, and a larger fire hole angle is difficult to process and realize on the original structure, and the thickness of the fire cover or the fire cover base where the fire hole is located must be heightened, which finally causes the increase of the height of the burner. The thickness of the fire cover or the fire cover base is increased, which easily causes the problem of poor fire transmission.
Unless supported by adequate evidence, the prior art described herein is not meant to be an admission that such prior art is well known to those of ordinary skill in the art to which the present application relates prior to the filing date of the present application.
[ application ]
One of the objects of the present application is to provide an improved burner cover for a gas burner, a burner comprising the burner, and a gas burner comprising the burner, which aim at least one of the above technical problems.
Another object of the present application is to provide a fire cover and a burner for a gas range, which can reduce the machining tolerance requirements, with respect to at least one of the above technical problems.
To achieve at least one of the above technical objects, the present application proposes, for example, the following technical solutions: a fire cover for a burner of a gas stove, wherein the bottom of the fire cover is inwards recessed to form a gas accommodating cavity, the bottom surface of the fire cover is provided with a first plane and a first inclined plane, the first plane is parallel to a horizontal plane, the first inclined plane is positioned at the periphery of the first plane, and the first inclined plane extends upwards obliquely from the inside of the fire cover to the outer side wall of the fire cover; a plurality of grooves are formed in the first plane at intervals, and extend obliquely upwards from the inside of the fire cover to the outer side wall of the fire cover; the groove is communicated with the air accommodating cavity, and penetrates through the first inclined plane and penetrates through the outer side wall of the fire cover.
It is to be noted that "the first plane is parallel to the horizontal" is based on the fact that the fire cover is placed or mounted on the horizontal, which is also most common. If the fire cover is placed or mounted on a slope intersecting a horizontal plane, the first plane then intersects the horizontal plane.
The first plane can be directly connected with the first inclined plane, and a wall or a surface can be arranged between the first plane and the first inclined plane.
In the technical scheme, the grooves are used for supplying fuel gas to flow out of the gas cavity to form flame. Because the groove is arranged on the first plane, the first plane is used for being attached to the other plane on the structure matched with the fire cover (the structure matched with the fire cover is for example a fire cover base) in the use state of the fire cover so as to seal the air containing cavity, and the fuel gas in the air containing cavity flows out of the groove only. Since the first plane and the horizontal plane are parallel, the problem of bevel processing mentioned in the background art is avoided in the processing of the planes. Inspection of the plane is easier.
In the technical scheme, the first plane is used for being attached to the other plane to seal the air accommodating cavity, so that the first inclined plane positioned on the periphery of the first plane does not need to be attached to the surface matched with the first inclined plane, and therefore the machining tolerance requirement on the first inclined plane can be correspondingly reduced. Therefore, the structure of the technical scheme is easier to process, and the yield is higher.
On the other hand, as the first inclined plane is positioned at the periphery of the first plane, the inclination angle of the first inclined plane can be processed to be larger, and the fire outlet angle has larger adjustment space so as to meet the combustion requirements of different combustors.
In a possible embodiment of the present application, the first plane is lower than the first inclined plane, or the first plane is connected to the lowest end of the first inclined plane.
In one possible embodiment of the application, the fire cover has a connecting wall which is located between the first plane and the first inclined surface and is connected to the first plane and the first inclined surface, respectively.
In one possible embodiment of the application, the connecting wall is perpendicular to the horizontal plane.
In one possible embodiment of the application, the first bevel is inclined at an angle ranging from [15 °,35 ° ], especially (25 °,35 ° ], and it is seen that, by modification of this embodiment, the first bevel may have a greater angle ranging from [15 °,35 ° ], and that it is difficult to machine a bevel having an inclination ranging from (25 °,35 ° ] on the fire cover prior to modification, wherein [15 °,35 ° ] is a mathematical expression referring to a range between 15 ° and 35 ° and including two end points (25 °,35 ° ] referring to a range between 25 ° and 35 ° and including an end point of 35 °, and excluding an end point of 25 °.
The application also provides a burner of a gas cooker, which comprises a burner cover base and a burner cover arranged on the burner cover base, wherein the bottom of the burner cover is inwards sunken to form a gas accommodating cavity, the bottom surface of the burner cover is provided with a first plane and a first inclined plane, the first plane is parallel to the horizontal plane, the first inclined plane is positioned at the periphery of the first plane, and the first inclined plane extends upwards in an inclined way from the inside of the burner cover to the outer side wall of the burner cover; a plurality of grooves are formed in the first plane at intervals, and extend obliquely upwards from the inside of the fire cover to the outer side wall of the fire cover; the groove is communicated with the air accommodating cavity and penetrates through the first inclined plane and penetrates through the outer side wall of the fire cover; the fire cover base is provided with a second plane parallel to the horizontal plane corresponding to the first plane; the fire cover base is provided with a second inclined plane corresponding to the first inclined plane, and the second inclined plane extends upwards in an inclined manner from the inside of the fire cover base to the outer side wall of the fire cover base; in the using state of the furnace end, the first plane is attached to the second plane; the groove, the second plane and the second inclined plane jointly enclose a fire outlet channel, and the fire outlet channel is used for flowing out the fuel gas in the gas containing cavity to form flame.
Wherein "the fire cover base is provided with a second plane parallel to the horizontal plane corresponding to the first plane" is also most commonly based on the fire cover base being placed or mounted on the horizontal plane. If the fire cover base is placed or mounted on an inclined plane intersecting a horizontal plane, the second plane then intersects the horizontal plane.
The technical scheme has the beneficial effects that the first plane is used for being attached to the second plane in the using state of the furnace end so as to seal the gas containing cavity, so that the gas in the gas containing cavity flows out of the fire outlet channel only. Therefore, the first inclined plane positioned at the periphery of the first plane can be free from being attached to the second inclined plane, and a small gap is allowed between the first inclined plane and the second inclined plane, so that the requirements on machining tolerances of the first inclined plane and the second inclined plane can be correspondingly reduced, and the machining yield of the fire cover and the fire cover base is improved. Of course, this does not mean that the above-described solution excludes the case where the first inclined surface is attached to the second inclined surface.
On the other hand, the inclination of first inclined plane and second inclined plane can process more, and the angle of producing the fire has bigger adjustment space to satisfy the burning demand of different combustors.
On the premise of considering production cost and meeting performance requirements, in one possible implementation mode of the application, in a use state of the burner, a gap is reserved between the first inclined plane and the second inclined plane.
In one possible embodiment of the present application, the fire cover base further has a vertical wall, the vertical wall is located between the second plane and the second inclined plane, and the vertical wall is connected to the second plane and the second inclined plane, respectively, and the vertical wall and the second plane define a concave corner portion. In the use state of the burner, the gas flow forms vortex at the corner. When flame burns inwards from the fire outlet channel and backfire possibly occurs, vortex generated by the corner part forms certain resistance, and air can be prevented from entering the fire outlet channel, so that backfire is avoided.
In a possible embodiment of the application, the fire cover is provided with a connecting wall corresponding to the vertical wall, the connecting wall is positioned between the first plane and the first inclined plane and is respectively connected with the first plane and the first inclined plane; in the use state of the burner, the vertical wall and the connecting wall are in compliance fit.
In order to define that the direction of the gas flowing out of the fire channel is inclined upwards, so that the flame inclined upwards is used for heating the cooking utensil above the stove head, in one possible implementation mode of the application, the groove comprises a top wall, the top wall faces the fire cover base in the use state of the stove head, and the top wall extends upwards in an inclined way from the inside of the fire cover to the outer side wall of the fire cover.
In one possible embodiment of the application, the angle of inclination of the top wall with respect to the horizontal is in the range of [15 °,35 ° ], in particular (25 °,35 ° ].
In a possible embodiment of the present application, the top wall is parallel to the first inclined plane.
In one possible embodiment of the present application, the groove and the second plane enclose a first portion of the fire outlet channel, the groove and the second inclined plane enclose a second portion of the fire outlet channel, and a dimension of the first portion in the gas flow direction is larger than that of the second portion. Thus, when the fuel gas flows, a stable spraying trend can be formed in the first part, and even if the first inclined surface and the second inclined surface of the second part are not jointed, a small gap exists, the influence on the flow of the fuel gas is small.
In one possible embodiment of the present application, the groove includes a main flame groove and a flame stabilizing groove, the main flame groove having a depth and/or a width greater than the flame stabilizing groove, and the main flame groove and the flame stabilizing groove being alternately arranged therebetween.

[ detailed description ] of the application
For a further understanding of the objects, construction, features, and functions of the application, reference should be made to the following detailed description of the preferred embodiments.
As shown in fig. 1, fig. 1 is a perspective view of a burner cover for a gas range according to an embodiment of the present application.
The fire cover 10 of the present embodiment is used on a burner of a gas range. The bottom of the fire cover 10 is recessed inward to form a gas-accommodating chamber 100.
The bottom surface of the fire cover 10 is formed with a first plane 110 and a first inclined surface 120, the first plane 110 is parallel to the horizontal plane, and the first inclined surface 120 is located at the periphery of the first plane 110. The first inclined surface 120 extends obliquely upward from the inside of the fire cover 10 toward the outer side wall 11 of the fire cover 10. In the use state of the fire cover 10, the first plane 110 is lower than the first inclined plane 120.
The first flat surface 110 and the first inclined surface 120 are machined by a lathe.
The first bevel 120 may also be considered to be formed by cutting a portion of the fire cover 10 from the first plane 110.
The first plane 110 is provided with a plurality of grooves 115 at intervals, and the grooves 115 extend obliquely upwards from the inside of the fire cover 10 to the outer side wall 11 of the fire cover 10. The recess 115 communicates with the plenum 100, and the recess 115 penetrates the first inclined surface 120 and penetrates the outer sidewall 11 of the fire cover 10.
The fire cover 10 further has a connecting wall 130, and the connecting wall 130 is located between the first plane 110 and the first inclined surface 120 and is connected to the first plane 110 and the first inclined surface 120, respectively. In this embodiment, the connecting wall 130 is perpendicular to the horizontal plane.
In this embodiment, the first inclined surface 120 is inclined at an angle of 35 ° with respect to the horizontal plane.
The angle at which the first inclined surface 120 is inclined with respect to the horizontal plane may be selected according to the performance, structure, etc. of the burner. For example, in consideration of the energy efficiency requirement of the burner, the fire outlet angle of the fire cover needs to be designed to be larger, and then the angle of inclination of the first inclined plane 120 relative to the horizontal plane can be in the range of (25 °,35 ° ].
The fire cover 10 of the present embodiment is annular and is an outer annular fire cover, but the present application is not limited thereto, and the fire cover structure of the present embodiment may also be adopted as the inner annular fire cover structure. The fire cover 10 has a top surface 12 parallel to the horizontal plane and a circumferentially extending outer side wall 11. In order to shield the spills and reduce the likelihood of the spills blocking the recess 115, the fire cover 10 is provided with a visor portion 13 protruding outwardly of the fire cover 10 above the outer side wall 11.
The groove 115 of the present embodiment further includes a main flame groove 115a and a flame stabilizing groove 115b, wherein the main flame groove 115a has a depth and a width larger than those of the flame stabilizing groove 115b, and the main flame groove 115a and the flame stabilizing groove 115b are alternately arranged at intervals. Thus, the relatively small flame formed by the gas flowing out of the flame stabilizing groove 115b functions as a flame stabilizing function for stabilizing the large flame formed by the gas flowing out of the main flame groove 115a in addition to heating.
The burner of the gas stove according to the embodiment of the present application will be described again, and for the sake of clarity, the burner of the present embodiment does not completely show the relevant structure of the central area of the burner.

The first plane 110 is provided with a plurality of grooves 115 at intervals, and the grooves 115 extend obliquely upwards from the inside of the fire cover 10 to the outer side wall 11 of the fire cover 10. The recess 115 communicates with the plenum 100, and the recess 115 penetrates the first inclined surface 120 and penetrates the outer sidewall 11 of the fire cover 10.
The fire cover base 20 is provided with a second plane 210 parallel to the horizontal plane corresponding to the first plane 110.
The fire cover base 20 is provided with a second inclined surface 220 corresponding to the first inclined surface 120, and the second inclined surface 220 extends obliquely upwards from the inside of the fire cover base 20 to the outer side wall 21 of the fire cover base 20.
The second plane 210 and the second inclined plane 220 are also machined by a lathe.
As shown in fig. 4 and 5, in the use state of the burner 1, the first plane 110 is attached to the second plane 210. Referring to fig. 6 and 7, the recess 115, the second plane 210 and the second inclined plane 220 together define a flame outlet channel 300, and the flame outlet channel 300 is used for discharging the fuel gas in the gas containing cavity 100 to form flame.
It can be seen that the first plane 110 is attached to the second plane 210, and closes the gas-containing chamber 100, so that the fuel gas in the gas-containing chamber 100 can only flow out from the fire outlet channel 300.

In this embodiment, the top wall 1151 is also inclined at an angle of 35 ° with respect to the horizontal. The first inclined surface 120 is inclined at an angle of 35 ° with respect to the horizontal plane. Therefore, the top wall 1151 is parallel to the first inclined surface 120. In addition, the second inclined surface 220 of the fire cover base 20 of the present embodiment is inclined at an angle of 35 ° with respect to the horizontal plane.
