It should be understood that a gas range is a device for generating a flame by burning fuel gas, and the fuel gas is mixed with air to form a mixed gas after the fuel gas is introduced into the gas range and the mixed gas is ignited to form a flame.

The fuel gas input into the gas stove through the gas pipe can be mixed with primary air to form mixed gas, the primary air is sucked into the injection pipe in the process of inputting the gas into the injection pipe of the gas stove, so that the primary air and the gas are mixed to form the mixed gas, and the secondary air is air mixed with the gas again after the primary air and the gas are mixed.

In addition, it should be understood that, in the gas stove, no matter the primary air or the secondary air, the function of the gas stove is to enable the gas to be combusted more fully, so that, under the condition that the gas flow of the gas stove is constant, the higher the supply amount of the primary air and the secondary air is, the more fully the gas can be combusted, and further the gas stove has a better combustion effect.

In the present application, the combustion part 100 is a base member of a gas range, the combustion part 100 may provide a mounting base for at least some other components of the gas range, and a gas pipe may be connected to the combustion part 100 to supply gas into the combustion part 100. Have first gas mixing chamber 110 and second gas mixing chamber 130 in the combustion part 100, it should be understood that, the gas in first gas mixing chamber and the second gas mixing chamber 130 is the mist of gas and air, the gas is inputed to the combustion part 100 by the gas pipe in, and the primary air is inhaled to the back in the combustion part 100, the mist of gas and primary air is located the first gas mixing chamber 110 and the second gas mixing chamber 130 of combustion part 100, the mist continues to mix in first gas mixing chamber 110 and second gas mixing chamber 130 to make gas and air mix fully. The mixed gas in the first and second gas mixing chambers 110 and 130 of the combustion part 100 may be finally discharged through the fire holes of the combustion part 100 and ignited to form a flame.

The combustion part 100 is further provided with a first air channel 120 and a second air channel 140, the first air channel 120 is communicated with the first air mixing chamber 110, the second air channel 140 is communicated with the second air mixing chamber 130, air outside the gas stove can enter the first air channel 120 and the second air channel 140, and then the air is respectively input into the first air mixing chamber 110 and the second air mixing chamber 130 through the first air channel 120 and the second air channel 140 so as to supplement air to the first air mixing chamber 110 and the second air mixing chamber 130, so that the oxygen content in the mixed gas in the first air mixing chamber 110 and the second air mixing chamber 130 is further increased, and therefore, the first air channel 120 and the second air channel 140 in the combustion part 100 of the present application can be used as channels for supplementing secondary air.

Specifically, the combustion portion 100 of the present application further has a first air port 321 and a first fire hole 310, and the first air port 321 is communicated with the first air passage 120, so that the air in the first air passage 120 can be discharged through the first air port 321. The first fire holes 310 communicate with the first gas mixing chamber 110, so that the gas in the first gas mixing chamber 110 can be discharged through the first fire holes 310 and ignited to form flames. The first air hole 321 may be disposed at one side of the first fire hole 310, so that air discharged from the first air hole 321 may be supplemented to the first fire hole 310, so that gas discharged from the first fire hole 310 may be more sufficiently combusted, thereby supporting flame at the first fire hole 310. Of course, it should be understood that, after the gas in the first gas mixing chamber 110 is discharged through the first fire holes 310, the air located outside the combustion part 100 and near the first fire holes 310 may also support the flame at the first fire holes 310.

The combustion portion 100 of the present application further defines a first air groove 320, the first air port 321 is disposed in the first air groove 320, and specifically, the first air port 321 is disposed on an inner wall of the first air groove 320, so that the air in the first air channel 120 can first enter the first air groove 320 after being discharged through the first air port 321, and then is diffused in the first air groove 320. The air is diffused in the first air groove 320 and then discharged out of the first air groove 320 through the notch of the first air groove 320, thereby supplementing the secondary air to the flame generated at the first fire hole 310.

The air in the first air channel 120 enters the first air groove 320 and is diffused in the first air groove 320, so that the flow rate of the air can be reduced, and the air can be uniformly distributed in the first air groove 320, so that the air can act on a plurality of parts of the flame at the first fire hole 310 after being discharged through the notch of the first air groove 320, the plurality of parts of the flame at the first fire hole 310 can be fully supported by combustion, and finally, the combustion effect of the fuel gas discharged from the first fire hole 310 can be better.

Further, it is also understood that the air in the first air passage 120 may reduce the flow rate of the air after being diffused in the first air groove 320, so that the impact of the air on the flame may be reduced when the air flows toward the flame at the first fire holes 310, so that the flame at the first fire holes 310 may be more stable.

In the gas stove provided by the embodiment of the present application, air in the first air passage 120 of the combustion portion 100 may enter the first air groove 320 through the first air port 321, and the air may be diffused in the first air groove 320, so that the flow rate of the air may be reduced, and then the air may be discharged through the notch of the first air groove 320, because the first air groove 320 is disposed at one side of the first fire hole 310, the air in the first air groove 320 is discharged and then located at one side of the first fire hole 310, so that the air may be supplemented to the flame at the first fire hole 310, so as to achieve the purpose of supporting combustion of the flame at the first fire hole 310, and thus the flame at the first fire hole 310 may be prevented from being directly impacted by the air at a faster flow rate, so that the gas stove of the present application may also prevent the flame from being directly impacted by the air under the condition that the flame at the first fire hole 310 may sufficiently support combustion, and finally the combustion effect of the gas stove of the present application may be better.

In some embodiments, in order to make the flame generated by the gas range of the present application more stable, the area of the notch of the first air groove 320 of the combustion part 100 may be set to be larger than the opening area of the first air hole 321, and the air in the first air passage 120 may be discharged through the notch of the first air groove 320 after being diffused in the first air groove 320 through the first air hole 321, and the area of the notch of the first air groove 320 may be relatively larger, so that the air may be more sufficiently diffused after being discharged through the notch of the first air groove 320, and thus the distribution range of the air discharged through the notch of the first air groove 320 may be larger, so that the air may be supplemented to each part of the flame at the first fire hole 310, so that each part of the flame at the first fire hole 310 may be sufficiently supported, and finally the flame generated by the gas range of the present application may be more stable.

In some embodiments, in order that the first air mixing chamber 110 and the first air channel 120 may be formed in the combustion part 100 of the present application, the combustion part 100 may be configured to include the burner 200 and the inner cap 300, wherein the inner cap 300 may be configured to be disposed to cover the burner 200, and the burner 200 and the inner cap 300 may surround to form the first air channel 120 and the first air mixing chamber 110. Specifically, the burner 200 is provided with a groove structure, the groove structure can form a main structure of the first air mixing cavity 110 and the first air channel 120, and the inner fire cover 300 is covered on the burner 200 and then can cover the groove structure in the burner 200, so that the burner 200 and the inner fire cover 300 are surrounded to form the first air channel 120 and the first air mixing cavity 110. The first fire holes 310, the first air ports 321 and the first air slots 320 are all opened in the inner fire cover 300, and the first fire holes 310 and the first air ports 321 opened in the inner fire cover 300 are communicated with the groove structure in the burner 200.

The difficulty of preparing the combustion part 100 can be reduced by providing the combustion part 100 to be combined by the burner 200 and the inner cap 300, and the inner cap 300 can be easily detached from the burner 200 to clean the first air channel 120 and the first air mixing chamber 110.

Of course, in other embodiments, the first fire holes 310, the first air ports 321 and the first air grooves 320 of the combustion part 100 of the present application may also be disposed on the burner 200 and communicate with the groove structure in the burner 200, and the fire cover may still be disposed on the burner 200 to cover the groove structure in the burner 200.

In some embodiments, the inner fire cover 300 of the present application may be provided with a ring-shaped structure, so that a middle portion of the inner fire cover 300 has a through hole, which may allow the inner fire cover 300 to use less material to reduce the weight of the inner fire cover 300. When the inner fire cover 300 is an annular structure, the first fire holes 310 and the first air grooves 320 may be distributed in the inner fire cover 300 along the circumferential direction of the inner fire cover 300, and correspondingly, the first air mixing cavity 110 in the combustion part 100 is also distributed along the circumferential direction of the inner fire cover 300, and the first air mixing cavity 110 may be disposed corresponding to the first fire holes 310. After the first air grooves 320 and the first fire holes 310 are simultaneously distributed along the circumferential direction of the inner fire cover 300, and the first air grooves 320 are located at one side of the first fire holes 310, after the air in the first air channel 120 is discharged into the first air grooves 320 through the first air ports 321, the air can be diffused into the first air grooves 320, and after the air is sufficiently diffused into the first air grooves 320, the air can be distributed along the circumferential direction of the inner fire cover 300, so that the air discharged from the first air grooves 320 can be distributed along the circumferential direction of the inner fire cover 300. And because the first fire holes 310 are distributed along the circumferential direction of the inner fire cover 300, the flame generated at the first fire holes 310 also follows the circumferential direction of the inner fire cover 300, so that the air discharged from the first air groove 320 and distributed along the circumferential direction of the inner fire cover 300 can supplement the flame at the circumferential direction of the inner fire cover 300, and the combustion effect of each part of the flame generated by the gas stove of the present application is better.

Specifically, the number of the first fire holes 310 of the present application may be provided in plurality, and a plurality of the first fire holes 310 may be spaced apart from each other in the circumferential direction of the inner fire cover 300, or one first fire hole 310 may be provided and one first fire hole 310 may be continuously and separately arranged in the circumferential direction of the inner fire cover 300. The first air grooves 320 may be arranged to be continuously distributed along the circumferential direction of the inner fire cover 300, or the number of the first air grooves 320 may be provided in plurality, and a plurality of the first air grooves 320 may be spaced apart along the circumferential direction of the inner fire cover 300. The present application is not limited with respect to the specific arrangement of the first fire holes 310 and the first air slots 320.

In some embodiments, in order to further enable the air in the first air channel 120 to be uniformly distributed after flowing into the first air slot 320 through the first air port 321, the first air port 321 of the present application may also be disposed in the first air slot 320 along the circumferential direction of the inner fire cover 300. In this way, the first air passages 120 in the combustion portion 100 may also be arranged to be distributed along the circumferential direction of the inner fire cover 300, so that the first air ports 321 distributed along the circumferential direction of the inner fire cover 300 may all be communicated with the first air passages 120, the air discharged through the first air ports 321 after the first air ports 321 are distributed along the circumferential direction of the inner fire cover 300 may be naturally distributed in each part of the first air grooves 320, and then the air distributed in each part of the first air grooves 320 may be further diffused in the first air grooves 320, so that the air discharged into the first air grooves 320 from the first air passages 120 may be more efficiently diffused in each part of the first air grooves 320.

Specifically, the first air ports 321 on the inner fire cover 300 may be continuously arranged along the circumferential direction of the inner fire cover 300, in addition, the number of the first air ports 321 may be plural, and the plural first air ports 321 may be arranged along the circumferential direction of the inner fire cover 300 at intervals, and the specific arrangement manner of the first air ports 321 of the inner fire cover 300 is not limited in this application.

In some embodiments, in order to make the air input into the first air groove 320 from the first air channel 120 diffuse into the first air groove 320 and then be efficiently discharged from the first air groove 320, the first air port 321 of the inner fire cover 300 of the present application may be oriented toward the notch of the first air groove 320, so that the inner wall of the first air groove 320 does not block the air input into the first air groove 320 from the first air channel 120 through the first air port 321.

Specifically, the first air port 321 may be disposed at the bottom wall of the first air tank 320, such that the first air port 321 faces the slot of the first air tank 320, such that the flow direction of the air output through the first air port 321 faces the slot of the first air tank 320, such that the air input into the first air tank 320 may be more efficiently discharged from the slot of the first air tank 320, and the air may be diffused into the first air tank 320 during the flow toward the slot of the first air tank 320, such that an equilibrium is reached between the air being efficiently discharged through the slot of the first air tank 320 and being diffused into the first air tank 320 to prevent the air from directly striking the flame.

In some embodiments, in the case that the inner fire cover 300 of the present application is provided as a ring-shaped structure, the first fire holes 310, the first air ports 321, and the first air grooves 320 may be all provided on the sidewall of the inner fire cover 300. The inner fire cover 300 is disposed on the burner 200, so that the direction from the burner 200 to the inner fire cover 300 is the same as the axial direction of the inner fire cover 300, and the first air groove 320 and the first fire hole 310 may be sequentially disposed in the direction from the burner 200 to the inner fire cover 300. Specifically, when the gas range of the present application is placed on the cooktop in use, the height of the first fire hole 310 is higher than that of the first air tank 320.

It should be understood that the gas discharged from the first fire holes 310 of the inner fire cover 300 is ignited to form flames, which may increase the temperature of the inner fire cover 300, and accordingly, the air located in the first air groove 320 may be heated, such that the temperature of the air discharged through the first air groove 320 is high, the high temperature air may naturally rise after being discharged through the first air groove 320, and since the first fire holes 310 are higher than the first air groove 320, and both the first fire holes 310 and the first air groove 320 are disposed at the side wall of the inner fire cover 300, the air discharged through the first air groove 320 may naturally rise to the first fire holes 310 of the inner fire cover 300, for the purpose of supplementing secondary air to the flames generated at the first fire holes 310.

In addition, in the direction of furnace end 200 to interior fire lid 300, the internal diameter of interior fire lid 300 can set up to crescent, the inside wall of interior fire lid 300 is the conical surface like this, therefore, when first fire hole 310 and first air groove 320 set up on the lateral wall of the interior fire lid 300 of conical surface, the contained angle that the opening orientation of first fire hole 310 and the orientation of the notch of first air groove 320 were all with the axial of interior fire lid 300 is less than 90 degrees, like this when the gas-cooker of this application is placed and is used on the top of a kitchen range, the air that discharges through the notch of first air groove 320 and the gas that discharges through first fire hole 310 all flow to the upside of interior fire lid 300, thereby can make the flame that produces at interior fire lid 300 extend upwards, after the pan that waits to heat is placed in the upside of interior fire lid 300, can make the flame that interior fire lid 300 department produced can more fully act on the pan that is located the upside of interior fire lid 300.

In some embodiments, in order to make the gas injected from the first fire hole 310 of the inner fire cover 300 burn sufficiently, so that the gas stove of the present application has a better combustion effect, the inner fire cover 300 may further be provided with a first gas supplement port 331, and the first gas supplement port 331 is communicated with the first gas mixing chamber 110, so that the gas in the first gas mixing chamber 110 may be discharged through the first fire hole 310 and the first gas supplement port 331, and the flow rate of the gas discharged through the first gas mixing chamber 110 may be increased by providing the first gas supplement port 331, and the gas discharged from the first fire hole 310 and the first gas supplement port 331 may be sufficiently combusted by matching with the air discharged from the first air groove 320.

Specifically, the first gas supplement port 331 may be disposed on an inner sidewall of the inner fire cover 300 and located at a side of the first fire hole 310 facing away from the first air groove 320, such that the first fire hole 310 is located between the first air groove 320 and the first gas supplement port 331, and both the first fire hole 310 and the first gas supplement port 331 are higher than the first air groove 320, and air exhausted from the first air groove 320 may be supplemented to positions of gas exhausted from the first fire hole 310 and the first gas supplement port 331, so that gas exhausted from the first fire hole 310 and the first gas supplement port 331 may be sufficiently combusted.

In some embodiments, in order to prevent the gas discharged through the first gas supplement port 331 from impacting the flame generated on the inner fire cover 300, the inner fire cover 300 of the present application may further include a first flame holding groove 330, and the first gas supplement port 331 may be disposed in the first flame holding groove 330, so that the gas discharged through the first gas supplement port 331 may enter the first flame holding groove 330 in advance, and the gas may be discharged through the notch of the first flame holding groove 330 after being diffused in the first flame holding groove 330, thereby achieving the purpose of reducing the flow rate of the gas discharged through the first gas supplement port 331, so that the gas may not directly impact the flame generated on the inner fire cover 300.
