Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0033] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0035] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0036] The combustion process of a gas stove is as follows: High-pressure gas enters the valve body of the gas stove from the gas pipeline. After the valve body is opened, it flows into the nozzle. Since the nozzle size is very small, generally less than 2 mm, the high-pressure gas becomes high-speed and low-pressure gas after flowing out of the nozzle, enters the Venturi structure of the burner head to form a negative pressure (lower than atmospheric pressure), so the primary air is entrained and flows into the burner head, mixes with the gas and flows out of the burner head into the gas distribution plate and the burner cap for combustion. During the combustion process, the air in the environment will be supplemented for the second time, that is, the secondary air, to ensure the complete combustion of the gas. It can be seen from the working principle that the primary air volume and the secondary air volume are the core key factors to ensure the complete combustion of the gas.

[0037] Up-draft gas stoves generally have the problem of insufficient primary air volume. Domestic residents prefer high-fire cooking for frying, boiling, and stir-frying, and have a high requirement for the intensity of the firepower. Existing ejectors have great limitations in solving such related problems. Due to the serious shortage of primary air volume, more secondary air is needed for complete combustion, but the secondary air supplement of existing burners is very limited, especially in the inner side of the inner burner cap and the area between the inner burner cap and the outer burner cap.

[0038] Based on this, the embodiments of the present application provide a burner and a gas stove to improve the primary air supplement amount of the burner and improve the combustion efficiency of the burner.

[0039] On the one hand, the embodiments of the present application provide a burner.

Since the air distribution plate 100 of the burner is provided with an air guiding cavity 410, the air outlet part of the blower is communicated with the inside of the inner ring burner cap 200 and / or the inside of the outer ring burner cap 300 through the air guiding cavity 410. In this way, primary air can be supplemented to the air guiding cavity 410 by the blower, and the primary air is then supplemented to the inside of the inner ring burner cap 200 and / or the inside of the outer ring burner cap 300 to supplement the primary air supply amount of the inner ring burner cap 200 and / or the outer ring burner cap 300, so as to increase the primary air that can undergo a combustion reaction with the combustion, promote complete combustion, reduce carbon monoxide in the combustion, and improve the combustion efficiency.

[0043] It should be noted that when the embodiment of the present application is actually implemented, the air outlet part of the blower can be communicated with only the inside of the inner ring burner cap 200 through the air guiding cavity 410 to increase the supply amount of primary air to the inner ring burner cap 200; or, the air outlet part of the blower can be communicated with only the inside of the outer ring burner cap 300 through the air guiding cavity 410 to increase the supply amount of primary air to the outer ring burner cap 300; or, the air outlet part of the blower can be communicated with both the inside of the inner ring burner cap 200 and the inside of the outer ring burner cap 300 through the air guiding cavity 410 to increase the supply amount of primary air to the inner ring burner cap 200 and the outer ring burner cap 300, so as to improve the combustion efficiency.

[0060] Further, in combination with Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , the burner in the embodiment of the present application further includes a nozzle 700. The air inlet end of the nozzle 700 is used to connect to the burner head, and the air outlet end of the nozzle 700 is communicated with the air guiding cavity 410. The primary air and the fuel gas can be introduced into the nozzle 700 through the burner head, and then supplemented into the air guiding cavity 410 through the nozzle 700, and then distributed to the inside of the inner ring burner cap 200 or / and the inside of the outer ring burner cap 300 to supplement the amount of primary air inside the inner ring burner cap 200 or / and the inside of the outer ring burner cap 300, so as to increase the primary air that can undergo a combustion reaction with the combustion, promote complete combustion, reduce carbon monoxide in the combustion, and improve the combustion efficiency.

[0061] In combination with Figure 3 、 Figure 4 and Figure 5 , in order to optimize the spatial layout, the air inlet end of the nozzle 700 can be penetrated through the first fitting 620. The air inlet end of the nozzle 700 can be connected to the burner head through an air inlet member 800. The first fitting 620 can be connected to the air inlet member 800 by means of integration or other connection methods. The first fitting 620 and the air inlet member 800 are provided with an air inlet passage 900 communicated with the air inlet end of the nozzle 700. The air outlet end of the nozzle 700 penetrates through the air outlet part of the second fitting 630 with a gap to communicate with the air guiding cavity 410 of the air guiding member 400. In actual implementation, the primary air and the fuel gas can be introduced into the nozzle 700 through the burner head and the air inlet passage 900, and discharged from the air outlet end of the nozzle 700 to form a first stream of mixed fuel gas; at the same time, under the action of the fan, the primary air is introduced into the installation cavity 510 of the installation member 500 through the air inlet part, and then introduced into the transition cavity 610 through the first air outlet part. The primary air introduced into the transition cavity 610 is discharged through the gap between the air outlet end of the nozzle 700 and the air outlet part of the second fitting to form a second stream of primary air; the first stream of mixed fuel gas is mixed with the second stream of primary air to be supplemented into the air guiding cavity, and then distributed to the inside of the inner ring burner cap 200 or / and the inside of the outer ring burner cap 300 to supplement the amount of primary air inside the inner ring burner cap 200 or / and the inside of the outer ring burner cap 300, so as to increase the primary air that can undergo a combustion reaction with the combustion, promote complete combustion, reduce carbon monoxide in the combustion, and have better combustion efficiency.

[0062] Combined with Figure 3 , an ejector 1000 is provided between the transition piece 600 and the air extraction cavity 410. There are gaps between both ends of the ejector 1000 and the transition piece 600 as well as the air extraction cavity 410. The ejector 1000 is provided with an ejection channel 1010. The centerlines of the nozzle 700 on the transition piece 600, the ejection channel 1010, and the opening of the air extraction cavity 410 are preferably located on the same straight line. During actual implementation, the above-mentioned first mixture of combustible gas and the second primary air will have a relatively high air pressure and a relatively fast flow rate. Therefore, when the first mixture of combustible gas and the second primary air sequentially enter the ejection channel 1010 and the air extraction cavity 410 through the nozzle 700, external air can be introduced into the air extraction cavity 410 through the gaps between the ejector 1000 and the transition piece 600 and between the ejector 1000 and the air extraction cavity 410, making the supplement of primary air more sufficient to further improve the combustion efficiency.

[0063] It should be noted that in the embodiment of the present application, the air intake piece 800 can be integrated on the mounting piece 500, that is, the two can be integrally formed. The nozzle 700 can also be arranged at other positions, that is, the air outlet end of the nozzle 700 and the air outlet part of the second fitting 630 are respectively communicated with the air extraction cavity 410, and the burner can also have good combustion efficiency.

[0064] Preferably, combined with Figure 1 , there are two transition pieces 600, and the transition cavities 610 of the two transition pieces 600 are respectively communicated with the mounting cavity 510 and the air extraction cavity 410.

The mounting cavity 510 is respectively provided with two first air outlet parts, and the two first air outlet parts are respectively communicated with the two transition cavities 610 correspondingly; and the air extraction cavity 410 can also be provided with two, and the two air extraction cavities 410 are respectively communicated with the two transition cavities 610 correspondingly.

[0065] In addition, limited by space and the different requirements for primary air inside the inner ring burner cap 200 and the outer ring burner cap 300 (the content of primary air required inside the inner ring burner cap 200 is less than the content of primary air required inside the outer ring burner cap 300), in the embodiment of the present application, the ejector 1000 is only provided between the transition piece 600 and the air extraction cavity 410 communicated with the inside of the outer ring burner cap 300, and no ejector 1000 is provided between the transition piece 600 and the air extraction cavity 410 communicated with the inside of the inner ring burner cap 200, that is, only one ejector 1000 is provided. Of course, in other implementation schemes, two ejectors 1000 can also be provided, and the two ejectors 1000 can be respectively arranged between the transition piece 600 and the two air extraction cavities 410 communicated with the inside of the two burner caps. The embodiment of the present application does not limit this.

[0067] Preferably, a plurality of first air inlet holes and second air inlet holes in the embodiment of the present application can be provided to improve the balance of the primary air supply to the inside of the outer ring burner cap 300 and the inside of the inner ring burner cap 200.

[0068] On the other hand, the present application also provides a gas stove, which includes the above-mentioned burner. The gas stove with the above-mentioned burner can supply secondary air to the air guiding cavity 410 of the air guiding member 400 through a blower. The secondary air is then supplemented to the inner circle of the inner ring burner cap 200 or / and the area between the inner ring burner cap 200 and the outer ring burner cap 300 through the air inlet part on the air distributing plate 100, so as to supplement the secondary air supply amount of the inner ring burner cap 200 or / and the outer ring burner cap 300, so as to increase the secondary air that can undergo a combustion reaction with combustion, promote complete combustion, reduce carbon monoxide in combustion, and improve combustion efficiency.

[0069] It should be noted that the blower in the embodiment of the present application can also be independently arranged from the air distributing plate 100, and the air outlet part of the blower can be connected to the air guiding cavity 410 on the air distributing plate 100 through a connecting piece.
