Description

Technical Field

[0001] The present invention relates to the field of stove burners, and in particular to a top-air-inlet stove burner and a stove comprising the same. Background Art

[0002] The burner and overall structure of conventional top-inlet stoves are relatively complex. The gas nozzle, ejector tube, and gas mixing chamber are independently supported on the base, which occupies a significant amount of space on the upper end of the base, making it difficult to clean. This also leads to problems such as difficult structural arrangement of the ejector, poor ejection performance, and poor secondary air supply. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the upper end surface of the base of the upper air inlet stove burner occupies a large space, which is not conducive to cleaning, and provide an upper air inlet stove burner and a stove including the same.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A top-inlet stove burner includes a gas mixing chamber, a fire cover, and an ejector pipe. The gas mixing chamber has a gas mixing cavity with an upper end open. The fire cover is arranged above the gas mixing chamber and covers the gas mixing cavity. The ejector pipe is connected to the gas mixing cavity. The top-inlet stove burner also includes:

[0006] A base, the gas mixing chamber and the ejector pipe are both arranged above the base, and the ejector pipe and the gas mixing chamber are suspended relative to the base;

[0007] The nozzle seat is fixed on the upper end surface of the base, and the nozzle seat is provided with a gas nozzle in the direction of the air inlet of the ejector tube. The air inlet end of the ejector tube is connected to the nozzle seat, and the air outlet end of the ejector tube is connected to the mixing chamber. The ejector tube is used to introduce the gas ejected from the gas nozzle into the mixing chamber.

[0008] In this solution, the mixing chamber, flame cover, and ejector tube are supported by the nozzle holder, allowing them to be suspended relative to the base. Only the nozzle holder is directly mounted on the upper end surface of the base, while the remaining components are suspended, eliminating the space directly on the upper end surface and facilitating cleaning. Furthermore, since the mixing chamber, flame cover, and ejector tube are all suspended, secondary air can flow from the outer side of the top-inlet stove burner to the inner side through the suspended area below, ensuring more adequate secondary air supply and improving combustion efficiency.

[0009] Preferably, the nozzle seat is arranged on the axially outer side of the ejector tube, and the gas nozzle is arranged on the side wall surface of the nozzle seat.

[0010] Preferably, the gas nozzle extends into the interior of the ejector tube.

[0011] In this solution, the above-mentioned arrangement can ensure that more gas ejected from the gas nozzle enters the interior of the ejector tube, and then flows into the gas mixing chamber through the ejector tube, and is then used for combustion, thereby preventing excessive gas ejected from the gas nozzle from flowing to the outside of the ejector tube in advance through the gap between the gas nozzle and the ejector tube, thereby improving the utilization rate of the gas.

[0012] Preferably, the ejector tube is provided with an air inlet channel, the air inlet channel communicating the interior and exterior of the ejector tube, and the air inlet channel is provided at the air inlet end of the ejector tube.

[0013] In this solution, the air inlet channel is used to inject the external primary air into the ejector tube, and then flow into the gas mixing chamber together with the gas in the ejector tube for initial combustion.

[0014] Preferably, the air inlet channel is provided at the lower end of the ejector tube.

[0015] In this solution, the above arrangement can prevent liquid or debris from entering the interior of the ejector tube from the air inlet channel, thereby playing a dust-proof role and avoiding blockage of the ejector tube.

[0016] Preferably, the top air inlet stove burner further comprises a support plate, the support plate is fixed to the upper end of the ejector tube, and the upper end surface of the support plate is located above the fire cover.

[0017] In this solution, the support sheet serves as a supporting structure for supporting the pot, preventing the pot from directly pressing against the fire cover, thereby ensuring that the fire holes on the fire cover can produce fire normally.

[0018] Preferably, the support plate extends along the axial direction of the ejector tube toward the nozzle seat and exceeds the ejector tube. A limiting groove is provided on the top of the nozzle seat. The limiting groove is formed by being recessed downward from the upper end surface of the nozzle seat, and the support plate is partially accommodated in the limiting groove.

[0019] In this solution, the cooperation between the limiting groove and the supporting plate can realize the positioning and installation of the ejector tube and the nozzle seat on the one hand, and the connection between the ejector tube and the nozzle seat can be indirectly realized on the other hand. There is no need to set up the connection structure between the ejector tube and the nozzle seat, thereby simplifying the overall structure of the top air inlet stove burner.

[0020] Preferably, the gas mixing chamber comprises an inner gas mixing chamber and an outer gas mixing chamber, and the outer gas mixing chamber is arranged radially outward of the inner gas mixing chamber;

[0021] There are multiple ejector tubes, at least one ejector tube is communicated with the inner gas mixing chamber, and at least one ejector tube is communicated with the outer gas mixing chamber.

[0022] In this solution, the above arrangement enables both the inner mixing chamber and the outer mixing chamber to obtain sufficient fuel gas, ensuring uniform fire output on the inner and outer sides of the fire cover.

[0023] Preferably, a stopper is provided at the lower end of the base, and the stopper extends downward from the lower end surface of the base, and the stopper is used to abut against a stove panel of the stove.

[0024] In this solution, the upper air inlet stove burner is limited on the stove panel by the cooperation between the stopper and the stove panel, thereby preventing the upper air inlet stove burner from moving relative to the stove panel.

[0025] Preferably, the top air inlet stove burner further comprises a connecting rod, one end of which is connected to the lower end surface of the base, and the other end of which extends in a direction away from the base and is used to be connected to the housing of the stove.

[0026] In this solution, the upper air inlet stove burner is fixed relative to the stove shell by connecting the connecting rod to the stove shell, preventing the upper air inlet stove burner from shaking during use and improving the stability of the upper air inlet stove burner during use.

[0027] Preferably, the number of the connecting rod is one, and the connecting rod is arranged at the center of the base.

[0028] In this solution, the above arrangement simplifies the structure of the burner of the top air inlet stove while improving the stability of the support connecting rod supporting the base and other components.

[0029] A stove is characterized in that it comprises a stove panel and the top-inlet stove burner as described above, wherein the base of the top-inlet stove burner is mounted on the stove panel.

[0030] Preferably, the stove panel is provided with a mounting hole, and the mounting hole passes through the upper and lower ends of the stove panel;

[0031] A stopper is provided at the lower end of the base, and the stopper extends downward from the lower end surface of the base. The lower end surface of the base abuts against the upper end surface of the stove panel, and the outer peripheral surface of the stopper abuts against the inner wall surface of the mounting hole.

[0032] In this solution, the upper air inlet stove burner is limited on the stove panel by the cooperation between the stopper and the stove panel, thereby preventing the upper air inlet stove burner from moving relative to the stove panel.

[0033] Preferably, the stove further includes a shell connected to the lower end of the stove panel; the top air inlet stove burner further includes a connecting rod, the upper end of the connecting rod is connected to the lower end surface of the base, and the lower end of the connecting rod is connected to the shell.

[0034] In this solution, the upper air inlet stove burner is fixed relative to the stove shell by connecting the connecting rod to the stove shell, preventing the upper air inlet stove burner from shaking during use and improving the stability of the upper air inlet stove burner during use.

[0035] Preferably, a limiting hole is provided at one end of the shell facing the cooker panel, and the lower end of the connecting rod is accommodated in the limiting hole.

[0036] In this solution, the stopper holes cooperate with the connecting rod to quickly position the connecting rod on the housing, improving installation efficiency. The stopper holes restrict radial movement of the connecting rod, further preventing the top-inlet stove burner from shaking during use and improving its stability.

[0037] The present invention provides a positive improvement in that the mixing chamber, fire cover, and ejector tube are suspended relative to the base via the support of the nozzle holder. Only the nozzle holder is directly mounted on the upper end surface of the base, while the remaining components are suspended, eliminating the need for direct space on the upper end surface and facilitating cleaning. Furthermore, because the mixing chamber, fire cover, and ejector tube are all suspended, secondary air can flow from the lower suspended area, from the outside to the inside of the top-inlet stove burner. This allows for more adequate secondary air replenishment and improves combustion efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0072] like Figure 1 and Figure 2 As shown, this embodiment provides a stove comprising a stove panel 11, a stove burner, and a housing 13. The housing 13 is connected to the lower end of the stove panel 11. The stove panel 11 and the housing 13 together form a cavity 14 for accommodating components such as gas pipes, thereby protecting them. The stove burner is used to ignite gas, forming a flame that heats the cookware. The stove burner in this embodiment is an upper air intake stove burner 12, meaning that primary air is mixed with the gas above the stove panel 11.

[0073] like Figure 3-Figure 9 As shown, the top air inlet stove burner 12 includes a gas mixing chamber 2, a fire cover 3, an ejector tube 4, a base 5, a nozzle seat 6, a support plate 7, a stopper 8 and a connecting rod 9.

[0074] like Figure 3 、 Figure 5 and Figure 8 As shown, the interior of the gas mixing chamber 2 is provided with a gas mixing chamber 21, which has an opening at the top and a closed bottom. The gas mixing chamber 21 is used to accommodate the gas formed by the mixture of fuel gas and primary air. A fire cover 3 is provided above and fixed to the gas mixing chamber 2, and the gas mixing chamber 2 supports the fire cover 3. The fire cover 3 completely covers the opening at the top of the gas mixing chamber 21 and is provided with multiple fire holes 31. The fire holes 31 connect the interior space of the gas mixing chamber 21 with the exterior space. The mixed gas in the gas mixing chamber 21 can flow out through the fire holes 31 to the outside and ignite, thereby heating the cookware.

[0075] like Figure 5 、 Figure 6 and Figure 8 As shown, the outlet end of ejector tube 4 is connected to mixing chamber 2 and communicates with mixing cavity 21. Specifically, a through hole is provided on the side wall of mixing chamber 2, through which the outlet end of ejector tube 4 extends into mixing cavity 21. The connection between ejector tube 4 and the through hole is sealed, and the outlet port of the outlet end of ejector tube 4 communicates with mixing cavity 21. Ejector tube 4 is used to deliver the mixture of fuel gas and primary air into mixing cavity 21.

[0076] like Figure 5-Figure 7As shown, the nozzle holder 6 is provided with a gas nozzle 61 in the direction of the air inlet of the ejector tube 4. The air inlet end of the ejector tube 4 is connected to the nozzle holder 6, and the air inlet of the air inlet end of the ejector tube 4 is communicated with the gas nozzle 61, so that the ejector tube 4 introduces the gas ejected from the gas nozzle 61 into the gas mixing chamber 21. Specifically, a gas channel 62 is provided inside the nozzle holder 6. One end of the gas channel 62 is communicated with the gas pipeline below the cooker panel 11 for receiving gas, and the other end of the gas channel 62 is communicated with the gas nozzle 61. The gas nozzle 61 is used to eject the gas in the gas channel 62. The gas ejected by the gas nozzle 61 enters the interior of the ejector tube 4 through the air inlet at the air inlet end of the ejector tube 4, and then enters the gas mixing chamber 21 through the air outlet at the air outlet end of the ejector tube 4.

[0077] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, the base 5 is mounted on the cooktop 11, with the lower end surface of the base 5 abutting the upper end surface of the cooktop 11 to prevent liquids, debris, etc. from entering the cooktop through the gap between the base 5 and the cooktop 11. The cooktop 11 also supports the base 5. The gas mixing chamber 2, fire cover 3, ejector pipe 4, and nozzle holder 6 are all disposed above the base 5. Only the nozzle holder 6 is directly fixed to the upper end surface of the base 5. The base 5 is provided with a through hole for connecting the gas passage 62 of the nozzle holder 6 to the gas pipeline below the cooktop 11. The ejector pipe 4, gas mixing chamber 2, and fire cover 3 are suspended relative to the base 5 via the nozzle holder 6.

[0078] Specifically, since the fire cover 3 is installed on the mixing chamber 2, the mixing chamber 2 can support the fire cover 3. Since the outlet end of the ejector tube 4 is connected to the mixing chamber 2, the ejector tube 4 can support the mixing chamber 2. Since the inlet end of the ejector tube 4 is connected to the nozzle seat 6, the nozzle seat 6 can support the ejector tube 4. Through the force transmission effect, the force of the fire cover 3, the mixing chamber 2 and the ejector tube 4 is transmitted to the nozzle seat 6 in turn, thereby realizing the support of the ejector tube 4, the mixing chamber 2 and the fire cover 3 through the nozzle seat 6.

[0079] In this embodiment, the mixing chamber 2, fire cover 3, and ejector tube 4 are supported by a nozzle holder 6, achieving a suspended arrangement relative to the base 5. Only the nozzle holder 6 is directly mounted on the upper end surface of the base 5; the remaining components are suspended, eliminating the space directly occupied by the upper end surface of the base 5 and facilitating cleaning. Furthermore, since the mixing chamber 2, fire cover 3, and ejector tube 4 are all suspended, secondary air can flow from the lower suspended area, from the outside to the inside of the upper air inlet stove burner 12. This ensures more adequate secondary air replenishment and improves combustion efficiency.

[0080] The nozzle holder 6 and the base 5 can be integrally formed, or can be formed separately and then assembled.

[0081] like Figure 3 、 Figure 5-Figure 7 As shown, the nozzle seat 6 is arranged on the axial outside of the ejector tube 4, and the gas nozzle 61 is arranged on the side wall surface of the nozzle seat 6. The gas nozzle 61 extends into the interior of the ejector tube 4 to ensure that more gas ejected from the gas nozzle 61 enters the interior of the ejector tube 4, and prevents the gas ejected from the gas nozzle 61 from flowing too much from the gap between the gas nozzle 61 and the ejector tube 4 to the outside of the ejector tube 4 in advance, thereby improving the utilization rate of the gas.

[0082] In this embodiment, a small gap is provided between the air inlet of the ejector tube 4 and the sidewall of the nozzle holder 6. This ensures that the gas ejected from the gas nozzle 61 does not prematurely flow out of the ejector tube 4 through the gap between the gas nozzle 61 and the ejector tube 4, thereby reducing the precision of the fit between the two, improving processing efficiency, and reducing processing costs. In other alternative embodiments, the air inlet of the ejector tube 4 and the sidewall of the nozzle holder 6 may also abut against each other.

[0083] like Figure 5 and Figure 9 As shown, the ejector tube 4 is provided with an air inlet channel 41, which connects the interior and exterior of the ejector tube 4 and is located at the air inlet end of the ejector tube 4. The air inlet channel 41 is used to inject external primary air into the ejector tube 4, and then flows into the gas mixing chamber 2 together with the gas in the ejector tube 4 for initial combustion.

[0084] Furthermore, the air inlet channel 41 is provided at the lower end of the ejector tube 4 to prevent liquid or debris from entering the interior of the ejector tube 4 through the air inlet channel 41, thereby preventing dust and preventing blockage of the ejector tube 4. In other alternative embodiments, the air inlet channel 41 may also be provided at other locations on the ejector tube 4, such as the side or the upper end, and the specific design may be based on actual conditions.

[0085] like Figure 3 、 Figure 6 and Figure 8 As shown, the support piece 7 is fixed to the upper end of the ejector tube 4, and the upper end surface of the support piece 7 is located above the fire cover 3. The support piece 7 serves as a support structure for the pot, preventing the pot from directly pressing against the fire cover 3, and ensuring that the fire hole 31 on the fire cover 3 can emit fire normally.

[0086] like Figure 3 、 Figure 5 、 Figure 7 and Figure 8As shown, the support plate 7 extends along the axis of the ejector tube 4 toward the nozzle holder 6 and extends beyond the ejector tube 4. A retaining groove 63 is provided on the top of the nozzle holder 6. The retaining groove 63 is recessed downward from the upper end surface of the nozzle holder 6, and the support plate 7 is partially accommodated within the retaining groove 63. In this embodiment, the retaining groove 63 cooperates with the support plate 7 to achieve the positioning and installation of the ejector tube 4 and the nozzle holder 6. Furthermore, the retaining groove 63 cooperates with the support plate 7 to indirectly connect the ejector tube 4 and the nozzle holder 6. This eliminates the need for a connecting structure between the ejector tube 4 and the nozzle holder 6, thereby simplifying the overall structure of the top-inlet stove burner 12.

[0087] In this embodiment, the support plate 7 and the limiting groove 63 are engaged to achieve cooperation between the two. The connection method is simple, the connection efficiency is high, and it is convenient and quick to install and disassemble, so that the user can easily disassemble and clean the upper air inlet stove burner 12.

[0088] Furthermore, the limiting groove 63 is continuous at both ends along the axis of the ejector tube 4, thereby reducing the precision requirement for the extension length of the support plate 7, improving processing efficiency and reducing processing costs. In other alternative embodiments, the limiting groove 63 can also be continuous at one end toward the support plate 7 and closed at the end away from the support plate 7.

[0089] like Figure 3 As shown, the number of nozzle holders 6 in this embodiment is four, and the four nozzle holders 6 are respectively arranged at the four diagonal positions of the upper air inlet stove burner 12. The number of ejector tubes 4 is the same as the number of nozzle holders 6, which is also four. The nozzle holders 6 and the ejector tubes 4 are arranged in a one-to-one correspondence to ensure that the gas received by each area of ​​the mixing chamber 21 is uniform, and also ensure the stability of the support for the cookware.

[0090] Furthermore, if Figure 5 and Figure 8 As shown, the gas mixing chamber 21 includes an inner gas mixing chamber 211 and an outer gas mixing chamber 212, with the outer gas mixing chamber 212 being located radially outward of the inner gas mixing chamber 211. Two ejector pipes 4 are in communication with the inner gas mixing chamber 211, and two ejector pipes 4 are in communication with the outer gas mixing chamber 212, so that both the inner gas mixing chamber 211 and the outer gas mixing chamber 212 can receive sufficient fuel gas, ensuring uniform combustion on the inner and outer sides of the fire cover 3.

[0091] In other alternative embodiments, the number of nozzle holders 6 is at least three, and the plurality of nozzle holders 6 are evenly spaced along the circumference of the gas mixing chamber 2. The number of ejector tubes 4 is the same as the number of nozzle holders 6, and the nozzle holders 6 and ejector tubes 4 are arranged in a one-to-one correspondence. At least one ejector tube 4 communicates with the inner gas mixing chamber 211, and at least one ejector tube 4 communicates with the outer gas mixing chamber 212.

[0092] like Figure 2 、 Figure 4 and Figure 6As shown, the cooktop panel 11 is provided with a mounting hole 111, which extends through the upper and lower ends of the cooktop panel 11. A stopper 8 is provided at the lower end of the base 5, extending downward from the lower end surface of the base 5. The outer circumference of the stopper 8 abuts the inner wall of the mounting hole 111. In this embodiment, the stopper 8 cooperates with the cooktop panel 11 to limit the position of the upper air intake cooktop burner 12 on the cooktop panel 11, preventing the upper air intake cooktop burner 12 from moving relative to the cooktop panel 11. The stopper 8 in this embodiment is annular, and the shape of the outer circumference of the stopper 8 matches the shape of the inner wall of the mounting hole 111, so that all areas of the inner wall of the mounting hole 111 can abut against the outer circumference of the stopper 8, further limiting the movement of the upper air intake cooktop burner 12 relative to the cooktop 11.

[0093] like Figure 2 、 Figure 4 and Figure 6 As shown, the upper end of the connecting rod 9 is connected to the lower end surface of the base 5, and the lower end of the connecting rod 9 extends away from the base 5 and is connected to the housing 13. In this embodiment, the connection between the connecting rod 9 and the housing 13 of the cooker is used to secure the top-inlet cooker burner 12 relative to the cooker housing 13, preventing the top-inlet cooker burner 12 from shaking during use and improving the stability of the top-inlet cooker burner 12 during use.

[0094] Specifically, the connecting rod 9 in this embodiment is threadedly connected to the shell 13, the lower end of the connecting rod 9 is provided with an external thread, and a nut 131 is installed on the shell 13. The connection between the connecting rod 9 and the shell 13 is achieved by screwing the nut 131 and the connecting rod 9.

[0095] In other alternative embodiments, the connecting rod 9 and the housing 13 may also be connected in other ways.

[0096] In this embodiment, there is only one connecting rod 9, which is located at the center of the base 5. This simplifies the structure of the top-inlet stove burner 12 while improving the stability of the connecting rod 9 supporting the base 5 and other components. In other alternative embodiments, there may be multiple connecting rods 9, which can be located at any position on the base plate to ensure support stability.

[0097] Furthermore, if Figure 2As shown, the housing 13 has a retaining hole 132 at the end facing the cooktop 11. A nut 131 is received within the retaining hole 132, and the lower end of the connecting rod 9 extends into the retaining hole 132 and connects to the nut 131. In this embodiment, the retaining hole 132 cooperates with the connecting rod 9 to quickly position the connecting rod 9 on the housing 13, improving installation efficiency. The retaining hole 132 limits radial movement of the connecting rod 9, further preventing shaking of the upper-inlet cooktop burner 12 during use and improving its stability.
