[0032] This application provides a burner 1000, in combination with Figures 1 to 5 As shown, in some embodiments, the burner 1000 is provided with a first air passage 1500. The first air passage 1500 is adapted to communicate with the internal space of the gas stove, and the first air passage 1500 is adapted to allow the air in the internal space of the gas stove to flow along it (where "it" refers to the first air passage 1500) and be discharged. The so-called discharge means discharging the air from the internal space of the gas stove.

[0033] By providing the first air passage 1500 in the burner 1000, the first air passage 1500 communicates with the internal space of the gas stove. When the gas stove is operating, the internal space of the gas stove is heated, and the air in the internal space of the gas stove expands and thus is discharged from the internal space of the gas stove along the first air passage 1500. When this air is discharged from the internal space of the gas stove along the first air passage 1500, it also takes away the heat in the internal space of the gas stove, reducing the internal temperature rise of the gas stove and increasing the service life of the gas stove.

[0034] The burner head 1000 will be described in detail below in conjunction with a gas stove. The gas stove includes a housing and a burner 100. The housing includes a bottom shell and a panel. The panel covers the bottom shell so that a receiving space is formed between the panel and the bottom shell. Other components of the gas stove are installed in the receiving space. A part of the burner 100 is disposed in the receiving space, and another part of the burner 100 is exposed outside the housing (above the panel). The burner 100 includes a burner head 1000 and a burner cap 2000. A part of the burner head 1000 is disposed in the receiving space, and another part of the burner head 1000 is exposed outside the housing. The burner cap 2000 is covered on the burner head 1000. Generally speaking, the burner head 1000 has an inner ring chamber 1100 and an outer ring chamber 1200. The burner cap 2000 includes an inner ring burner cap 2100 and an outer ring burner cap 2200. The inner ring burner cap 2100 is covered on the inner ring chamber 1100, and the outer ring burner cap 2200 is covered on the outer ring chamber 1200. The inner ring burner cap 2100 is provided with inner ring fire holes, and the outer ring burner cap 2200 is provided with outer ring fire holes. Gas and primary air are introduced into the space between the inner ring chamber 1100 and the inner ring burner cap 2100 and ejected from the inner ring fire holes to be ignited to form an inner ring flame. Gas and primary air are introduced into the space between the outer ring chamber 1200 and the outer ring burner cap 2200 and ejected from the outer ring fire holes to be ignited to form an outer ring flame.

[0035] When the gas stove is working, the heat of the flame will be transferred to the burner cap 2000, the heat of the burner cap 2000 will be transferred to the burner head 1000, and the heat of the burner head 1000 will be transferred to the internal space of the gas stove. This will cause the temperature of the internal space of the gas stove to rise. Since there are other components installed in the internal space of the gas stove, excessive temperature rise will cause some components to fail or age prematurely, thus affecting the service life of the gas stove.

[0036] To solve the above problems, in this embodiment, the burner head 1000 is provided with a first air passage 1500 which is in communication with the internal space of the gas stove. When the gas stove is operating, the heat of the burner 100 is transferred to the internal space of the gas stove through the burner head 1000, causing the temperature of the internal space of the gas stove to rise. The air in the internal space of the gas stove expands and is discharged along the first air passage 1500, thereby causing the heat to be discharged from the gas stove along with the air. In this way, the temperature of the internal space of the gas stove can be reduced. As can be seen from the above, the internal space of the gas stove is enclosed by the bottom case and the panel. Therefore, the internal space of the gas stove is not isolated from the external space (the space outside the gas stove). When the air is discharged from the internal space of the gas stove through the first air passage 1500, the air in the external space can enter the internal space of the gas stove, and this cycle continues. After the air in the internal space of the gas stove is discharged through the first air passage 1500, since the burner head 1000 is relatively close to the flame, these air can participate in the combustion of the ejected gas, that is, the air ejected from the internal space of the gas stove constitutes secondary air. Since these air have a certain amount of heat, this can avoid too large a temperature difference when these air come into contact with the flame, which is beneficial to improving the combustion efficiency of the gas.

[0037] Combined with Figure 6 and Figure 7 As shown, in some embodiments, the first air passage 1500 extends along the vertical direction. The orientation in this article is referenced with the gas stove installed in the usage environment (such as a cabinet). The side of the gas stove close to the ground is the lower side, and the side away from the ground is the upper side. The air in the internal space of the gas stove is heated and discharged along the first air passage 1500. These air have the characteristic of floating. By designing the first air passage 1500 to extend along the vertical direction, the resistance of the air in the internal space of the gas stove flowing along the first air passage 1500 is smaller, and thus it can be discharged from the internal space of the gas stove faster.

[0038] For example, the first air passage 1500 includes a first inlet 1510 and a first outlet 1520. The first inlet 1510 is located below the first outlet 1520. The air in the internal space of the gas stove can enter the first air passage 1500 from the first inlet 1510 and then be discharged from the first outlet 1520. Since the first air passage 1500 extends along the vertical direction as a whole, the resistance of air flow can be effectively reduced.

[0039] Further, in some embodiments, when projected along the up-down direction, the projection of the first inlet 1510 and the projection of the first outlet 1520 at least partially overlap. It can be that part of the projection of the first inlet 1510 overlaps with part of the projection of the first outlet 1520, or the projection of the first inlet 1510 completely overlaps with the projection of the first outlet 1520, or the projection of the first inlet 1510 completely covers the projection of the first outlet 1520, or the projection of the first outlet 1520 completely covers the projection of the first inlet 1510. By such an arrangement, at least part of the air in the internal space of the gas stove can be discharged from the first outlet 1520 without turning after entering the first air passage 1500 from the first inlet 1510, further reducing the resistance of air flow and enabling the heat in the internal space of the gas stove to dissipate quickly.

[0040] Combined with Figure 8 As shown, in some embodiments, the burner head 1000 has an inner ring chamber 1100 and an outer ring chamber 1200. The outer ring chamber 1200 surrounds the inner ring chamber 1100, and a cavity 1400 is provided between the outer ring chamber 1200 and the inner ring chamber 1100. The cavity 1400 opens upward. The internal space of the gas stove is communicated with one end of the first air passage 1500, and the cavity 1400 is communicated with the other end of the first air passage 1500. In this way, the air discharged from the first air passage 1500 can flow more precisely into the cavity 1400, thereby supplementing secondary air for the inner ring flame.

[0041] Specifically, the burner head 1000 has an inner ring chamber 1100 and an outer ring chamber 1200. The burner cap 2000 includes an inner ring burner cap 2100 and an outer ring burner cap 2200. The inner ring burner cap 2100 covers the inner ring chamber 1100, and the outer ring burner cap 2200 covers the outer ring chamber 1200. The inner ring burner cap 2100 is provided with inner ring fire holes, and the outer ring burner cap 2200 is provided with outer ring fire holes. Gas and primary air are introduced into the space between the inner ring chamber 1100 and the inner ring burner cap 2100 and ejected from the inner ring fire holes to be ignited to form an inner ring flame. Gas and primary air are introduced into the space between the outer ring chamber 1200 and the outer ring burner cap 2200 and ejected from the outer ring fire holes to be ignited to form an outer ring flame. The air that enters the space between the inner ring chamber 1100 and the inner ring burner cap 2100 and the space between the outer ring chamber 1200 and the outer ring burner cap 2200 together with the gas is called primary air. During the combustion process of the gas, secondary air needs to be supplemented. Generally, the secondary air is supplemented by the flame entraining the air in the surrounding environment. Since the outer ring chamber 1200 surrounds the inner ring chamber 1100, the outer ring burner cap 2200 surrounds the inner ring burner cap 2100, that is, the outer ring flame surrounds the inner ring flame. The outer ring flame is closer, so it can conveniently entrain secondary air from the surrounding environment. The surrounding environment refers to the space above the panel outside the burner 100. Since the inner ring flame is closer to the inside, it is difficult for the inner ring flame to directly entrain secondary air from the surrounding environment. In this embodiment, by connecting the first air passage 1500 with the cavity 1400, when the air in the internal space of the gas stove is discharged through the first air passage 1500, it can enter the cavity 1400, so as to supplement the inner ring flame and provide secondary air for the full combustion of the inner ring flame. It can be understood that the connection can be direct or indirect. For example, one end of the first air passage 1500 forms a first inlet 1510, and the other end of the first air passage 1500 forms a first outlet 1520. When the burner 100 is installed in the housing, the first inlet 1510 is directly connected to the internal space of the gas stove, and the first outlet 1520 is indirectly connected to the cavity 1400 through the second air passage 1600.

[0042] The second air passage 1600 will be described below. In combination with Figures 1 to 4 and Figure 6 and Figure 8 As shown, in some embodiments, the burner head 1000 is provided with a second air passage 1600. The second air passage 1600 connects the cavity 1400 and the space above the panel of the gas stove. In this way, secondary air can be supplemented through the second air passage 1600.

[0043] Specifically, the second air passage 1600 has a second inlet 1610 and a second outlet 1620. The second inlet 1610 communicates with the space above the panel of the gas stove, and the second outlet 1620 communicates with the cavity 1400. For example, the second air passage 1600 extends along the radial direction of the burner 1000, so that the second inlet 1610 is located outside the outer ring chamber 1200, and the second outlet 1620 is located inside the outer ring chamber 1200. The air (secondary air) in the space above the panel of the gas stove can enter the second air passage 1600 from the second inlet 1610 and be discharged from the second outlet 1620 to the cavity 1400, and then supplemented to the inner ring flame. Through the cooperation of the second air passage 1600 and the first air passage 1500, the secondary air of the inner ring flame is supplemented through the first air passage 1500 and the second air passage 1600 respectively, and the supplement efficiency of the secondary air is higher, which is more conducive to the full combustion of the inner ring flame. It can be understood that there are various choices for the sizes and shapes of the first air passage 1500 and the second air passage 1600, which will not be limited one by one here. The number of the first air passage 1500 and the second air passage 1600 can also be set to multiple (two or more) according to the actual situation.

[0044] Combined with Figures 4 to 8 As shown, in some embodiments, the other end of the first air passage 1500 communicates with the second air passage 1600. Specifically, the first inlet 1510 of the first air passage 1500 communicates with the internal space of the gas stove, and the first outlet 1520 of the first air passage 1500 communicates with the second air passage 1600. The air in the internal space of the gas stove enters the first air passage 1500 from the first inlet 1510 and is discharged from the first outlet 1520 and then enters the second air passage 1600, and continues to flow along the second air passage 1600 and enters the cavity 1400. By communicating the other end of the first air passage 1500 with the second air passage 1600, the space occupied by the second air passage 1600 is fully utilized, which is beneficial to simplifying the structure.

[0045] Furthermore, combined with Figure 8As shown, the other end of the first air passage 1500 is disposed between the two ends of the second air passage 1600. In particular, when the first air passage 1500 is designed to extend in the up-down direction, this can prevent oil from entering the first air passage 1500 and falling into the internal space of the gas stove. It can be understood that when the gas stove is in use, it is easily contaminated by the outside world, and some oil, sundries, etc. will fall onto the burner 100 from top to bottom. Therefore, the other end of the first air passage 1500 is disposed between the two ends of the second air passage 1600. That is, one end of the first air passage 1500 constitutes the first inlet 1510, the other end of the first air passage 1500 constitutes the first outlet 1520, one end of the second air passage 1600 constitutes the second inlet 1610, the other end of the second air passage 1600 constitutes the second outlet 1620, and the first outlet 1520 is opened on the passage wall of the second air passage 1600 and is located between the second inlet 1610 and the second outlet 1620. In this way, the second air passage 1600 forms a shield for the first air passage 1500 in the top-down direction, preventing oil, sundries, etc. from entering the internal space of the gas stove through the first air passage 1500. In addition, by disposing the other end of the first air passage 1500 between the two ends of the second air passage 1600, the impact between the air entering the second air passage 1600 from the first air passage 1500 and the air entering the second air passage 1600 from the second inlet 1610 can be reduced, and the supplementary efficiency of the secondary air can be further improved.

[0046] Combined with Figure 5 、 Figure 6 and Figure 8 As shown, in some embodiments, a raised portion 1630 is provided on the bottom wall of the second air passage 1600, and the other end of the first air passage 1500 is disposed on the raised portion 1630. That is, the first outlet 1520 of the first air passage 1500 is formed on the raised portion 1630. It can be understood that oil, sundries, etc. will fall into the cavity 1400 and be discharged through the second air passage 1600, or enter the second air passage 1600 from the panel of the gas stove. By providing the raised portion 1630 on the bottom wall of the second air passage 1600, the first outlet 1520 of the first air passage 1500 is higher than the bottom wall of the second air passage 1600. Even if oil, sundries, etc. enter the second air passage 1600, the oil and sundries will flow along the bottom wall of the second air passage 1600 and it is difficult to enter the first air passage 1500 through the first outlet 1520, further preventing oil, sundries, etc. from entering the internal space of the gas stove through the first air passage 1500.

[0047] As shown in Figure 1, in some embodiments, the burner head 1000 further has a baffle 1300. The baffle 1300 is disposed at the bottom of the cavity 1400. For example, the burner head 1000 is integrally formed with an outer ring chamber 1200, an inner ring chamber 1100, and the baffle 1300. The baffle 1300 is disposed between the outer ring chamber 1200 and the inner ring chamber 1100. When oil, debris, etc. fall into the cavity 1400, they can be received by the baffle 1300. By connecting (such as being integrally formed) the baffle 1300 with the bottom wall of the second air passage 1600, it is convenient for oil, debris, etc. to be discharged from the baffle 1300 to the second air passage 1600 and then to the panel, facilitating the user to clean. Moreover, by making the baffle 1300 flush with the bottom wall of the second air passage 1600, on the premise of ensuring the flow area of the second outlet 1620, it is beneficial to compress the occupation of the axial space. It can be understood that the so-called flush means that the baffle 1300 and the bottom wall of the second air passage 1600 are as flat as possible.

[0048] A second aspect of the present application discloses a burner. As shown in combination with Figures 1 to 8 Figure 1, the burner includes a burner cap and the burner head of the above embodiment. The burner head 1000 is provided with a first air passage 1500. The first air passage 1500 is adapted to communicate with the internal space of the gas stove, and the first air passage 1500 is adapted to allow the air in the internal space of the gas stove to flow along it (where "it" refers to the first air passage 1500) and be discharged. The so-called discharge means discharging from the internal space of the gas stove.

[0049] By providing the first air passage 1500 in the burner head 1000, the first air passage 1500 communicates with the internal space of the gas stove. When the gas stove is working, the internal space of the gas stove is heated, and the air in the internal space of the gas stove expands and thus is discharged from the internal space of the gas stove along the first air passage 1500. When these airs are discharged from the internal space of the gas stove along the first air passage 1500, they also carry away the heat in the internal space of the gas stove, reducing the internal temperature rise of the gas stove and increasing the service life of the gas stove. It can be understood that the burner head of the burner adopts the technical solution of the above embodiment, so it has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0050] A third aspect of the present application discloses a gas stove. The gas stove includes the above burner. The burner of the gas stove in this embodiment adopts the technical solution of the above embodiment, so it has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0051] The above are only the preferred embodiments of the present application, which do not limit the patent scope of the present application. Any equivalent structural transformation made under the concept of the present application by using the content of the specification and drawings of the present application, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
