Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

Example 1

As shown in fig. 1 to 4, the present invention provides a burner of a cooking appliance, which includes a base 1, a fire cover 2 and an injection pipe (not shown in the drawings). The upper portion of the base 1 is opened, the fire cover 2 covers the top of the base 1, a gas mixing chamber 4 is formed by the surface of the inner side 2a of the fire cover 2 and the inner wall surface of the base 1 in a surrounding mode, and the outlet of the injection pipe is connected to the bottom of the base 1 and communicated to the gas mixing chamber 4.

The surface of the inner side 2a of the fire cover 2 is provided with a first groove 21 (see fig. 4), so that when the fire cover 2 and the base 1 are in a combined state, the first groove 21 is attached to the upper surface 1a of the base 1 (see fig. 3), the first groove 21 and the upper surface 1a of the base 1 jointly define a gas channel 5, the gas channel 5 is communicated to the gas mixing chamber 4 along the radial direction of the fire cover 2, the main fire hole 22 of the fire cover 2 extends inwards to the gas channel 5 along the downward inclined direction, the cross-sectional area of the main fire hole 22 is larger than that of the gas channel 5, so that the gas channel 5 can limit the gas flow entering the main fire hole 22, and after entering the gas mixing chamber 4 through the outlet of the injection pipe, the gas needs to enter the main fire hole 22 through the gas channel 5 and finally burns on the surface of the fire cover 2.

The invention utilizes the gas channel 5 formed by combining the first groove 21 of the inner side 2a of the fire cover 2 and the upper surface 1a of the base 1, so that the main fire hole 22 can be communicated with the gas mixing chamber 4, the sectional area of the gas channel 5 is limited by controlling the groove size of the first groove 21, the airflow pressure before the gas enters the main fire hole 22 from the gas mixing chamber is controlled, the airflow flow is buffered, and the problem of uneven outlet flow of the fire hole without a pressure stabilizing structure or poor pressure stabilizing effect is solved. Meanwhile, the size of the fit clearance between the first groove 21 on the inner side 2a of the fire cover 2 and the upper surface 1a of the base 1 is controlled, so that the air intake resistance can be adjusted, and the detonation phenomenon can be effectively controlled. Since the gas duct 5 and the main fire hole 22 are formed in two relatively independent structures, there is no concern that the reduction in the cross-sectional area of the gas duct 5 will affect the size of the main fire hole 22.

The invention combines the conventional circular fire holes and the tooth-shaped structure, and in a stove burner without a pressure stabilizing structure or with a poor pressure stabilizing effect, the tooth-shaped structure is used for stabilizing the pressure of gas flowing to the circular fire holes, so that the flow of the fire hole outlet is kept consistent, and the problem of uneven flame length of each fire hole is solved. Meanwhile, the groove-shaped structure is convenient to process, the gas channel 5 can be formed by combining the fire cover 2 and the base 1, the number of parts can be reduced, the cost of the furnace end is reduced, and meanwhile, materials are saved.

The stove burner has a plurality of gas passages 5 which are circumferentially and uniformly distributed along the circumferential direction of the fire cover 2 over the entire inner side 2a surface of the fire cover 2. Simultaneously, the main fire hole 22 of fire lid 2 sets up with these gas channel 5 one-to-one, and main fire hole 22 follows the surface of fire lid 2 and runs through fire lid 2 along the decurrent direction to on extending to the gas channel 5 that corresponds, single gas channel 5 can correspond the gas pressure of adjusting its fire hole that corresponds, so that the export flow in each fire hole keeps unanimous, guarantees that the flame length in each fire hole is even.

As shown in fig. 2, in the present embodiment, the base 1 includes two parts, namely, a base body 11 and a voltage stabilizing ring 12, wherein the voltage stabilizing ring 12 is sleeved on the upper surface 1a of the base body 11, so that the voltage stabilizing ring 12 can be detached from the base body 11. When the fire cover 2 is installed on the base 1, the first groove 21 of the fire cover 2 covers the upper surface 1a of the pressure stabilizing ring 12, namely, the upper surface 1a of the pressure stabilizing ring 12 and the first groove 21 jointly define the gas channel 5. Through set up detachable steady voltage ring 12 on base body 11, can conveniently dismantle and clean inside gas channel 5.

Meanwhile, when the cooker burner needs to be adapted to different gas types, the cross-sectional area of the gas channel 5 can be changed by directly replacing the fire cover 2 and the pressure stabilizing ring 12 to match the corresponding gas types. Because steady voltage ring 12 is separable state for base body 11, consequently can not cause the influence to base body 11 to the change of steady voltage ring 12, has guaranteed the structural integrity of cooking utensils combustor.

In this embodiment, the fire cover 2 is an outer ring fire cover 2, the main fire hole 22 is disposed on the outer side of the fire cover 2, and the pressure stabilizing ring 12 is correspondingly attached to the lower position of the outer side of the fire cover 2 to form a gas channel 5 communicated with the main fire hole 22 at the outer ring position of the fire cover 2. As shown in fig. 2, the inner ring of the fire cover 2 is directly positioned on the base body 11, and the outer ring of the fire cover 2 is indirectly positioned on the base body 11 through the pressure stabilizing ring 12.

It should be particularly noted that the specific structure of the base body 11 in the present embodiment is only for illustrative purposes, and the function of the base body 11 is only to show the relative positions of the fire cover 2, the pressure stabilizing ring 12 and the base body 11 in the present embodiment, and the position of the base body 11 relative to the air mixing chamber 4.

In addition, the fire cover 2 is also provided with a flame stabilizing hole 23, and the flame stabilizing hole 23 is not communicated with the gas channel 5, but directly penetrates through the fire cover 2 and is communicated with the gas mixing chamber 4. The hole position of flame stabilizing hole 23 on the surface of this fire lid 2 is located the top of the hole position of main fire hole 22, adopts the flame stabilizing structure promptly, provides the flame stabilizing function for corresponding main fire hole 22 to can reduce flame stabilizing hole 23 flow velocity, make the flame stabilizing effect better. Meanwhile, the outer side wall of the fire cover 2 extends horizontally outwards to form a waterproof brim 24, and the main fire hole 22 and the flame stabilizing hole 23 are both positioned below the waterproof brim 24, so that overflowing liquid is prevented from flowing into the fire hole of the fire cover 2 by the waterproof brim 24.

The flame stabilizing holes 23 and the main flame holes 22 are respectively arranged around the outer side wall of the flame cover 2 and are arranged in a ring shape at intervals, the aperture of the flame stabilizing holes 23 is smaller than that of the main flame holes 22, and the number of the flame stabilizing holes 23 is more than that of the main flame holes 22. The structure can ensure the firepower of the cooker burner (namely the fire hole size of the main fire hole 22), and the distribution density of the flame stabilizing holes 23 is increased, so that the time for the flame of the flame stabilizing holes 23 to completely transmit a whole circle is longer than that of the main fire hole 22, and the transmission speed of the flame on the outer ring of the fire cover 2 is further improved. For example, in the present embodiment, as can be seen from fig. 4, the number of flame stabilizing holes 23 is about twice that of the main fire holes 22.

In the present embodiment, referring to fig. 4, the first groove 21 is a rectangular groove so that the cross-sectional shape of the gas channel 5 formed is also rectangular. In a state of being a rectangular hole, the cross-sectional area of the gas passage 5 can be easily adjusted by adjusting the width and height of the gas passage 5. The width of the gas channel 5 depends on the distance between the two sidewalls of the first groove 21, and the height of the gas channel 5 depends on the distance between the top surface of the first groove 21 and the bracket on the upper surface 1a of the base 1. The purpose of adjusting the section area of the gas channel 5 at the front end of the fire hole can be realized by adjusting any one of the distances to correspond to different gas types. Preferably, the width of the gas channel 5 should be greater than the height of the gas channel 5, so that the depth of the first groove 21 can be reduced, and the processing difficulty of the groove structure can be further reduced.

Example 2

As shown in fig. 5 and 6, the present embodiment provides a cooktop burner, the structure and principle of which are substantially the same as those of the cooktop burner provided in embodiment 1, except that, in the present embodiment, the upper surface 1a of the pressure stabilizing ring 12 of the cooktop burner has a plurality of second grooves 121 at positions corresponding to the respective gas passages 5, and the second grooves 121 are combined together with the first grooves 21 of the fire cover 2 to constitute the gas passages 5. This structural arrangement has the following advantages compared to example 1:

for the stove burner, a plurality of pressure stabilizing rings 12 of different specifications may be simultaneously configured, and the difference between the pressure stabilizing rings 12 of different specifications is that the depths D of the second grooves 121 thereof are different from each other (see fig. 6). Through changing these steady voltage rings 12, make different steady voltage rings 12 when covering 2 combinations with the fire, can change the cross sectional area of gas channel 5 fast to adaptation in different gas types makes this cooking utensils combustor self possess the characteristics of quick adjustment in order to deal with different grade type gas access, has expanded the application range of this cooking utensils combustor.

In addition, it should be specifically noted that the solution in which the first groove 21 and the second groove 121 together form the gas channel 5 in the present embodiment is only a preferred embodiment of the present invention. In other embodiments, the inner side surface of the fire cover may not have the first groove, but only be a flat surface, and the second groove of the pressure stabilizing ring (or the base) is attached to the flat surface to enclose the gas channel, and this scheme can also rapidly adjust the cross-sectional area of the gas channel of the stove burner by replacing the pressure stabilizing ring (or the base) with different specifications to deal with the access of the gas with different specifications.
