SUMMARY

[0003] The utility model solves the technical problem to overcome the defects of the prior art, provide a kind of stove.

[0004] The utility model solves the above technical problem by the following technical scheme:

[0005] A kind of stove, the stove includes plug valve, explosive frying valve, nozzle mounting seat, inner ring injection pipe and outer ring injection pipe;

[0006] The plug valve includes inner ring gas passage, outer ring gas passage and explosive frying gas passage;The explosive frying valve includes explosive frying gas inlet passage and explosive frying gas outlet passage, and the explosive frying gas inlet passage is communicated with the explosive frying gas passage;

[0007] The nozzle mounting seat includes first inner ring passage, second inner ring passage, first outer ring passage and second outer ring passage;The gas inlet of the first inner ring passage is communicated with the gas outlet of the inner ring gas passage, the gas inlet of the second inner ring passage is communicated with the gas outlet of the explosive frying gas outlet passage, and the gas outlet of the first inner ring passage and the gas outlet of the second inner ring passage are all communicated to the inner ring injection pipe;The gas inlet of the first outer ring passage is communicated with the gas outlet of the outer ring gas passage, the gas inlet of the second outer ring passage is communicated with the gas outlet of the explosive frying gas outlet passage, and the gas outlet of the first outer ring passage and the gas outlet of the second outer ring passage are all communicated to the outer ring injection pipe;

[0008] The second inner ring passage is communicated with the second outer ring passage.

[0009] In this design, the second inner ring channel supplies gas for stir-frying to the inner ring, and the second outer ring channel supplies gas for stir-frying to the outer ring. The connection between the second inner and outer ring channels enables communication between the inner and outer rings for stir-frying gas. This allows gas originally intended for the inner ring to be supplied to the outer ring, and vice versa, resulting in a more even distribution of gas between the inner and outer rings. This leads to more uniform heating of the cookware and improved stir-frying performance.

[0010] Preferably, the stir-frying steam outlet channel includes an inner ring stir-frying steam outlet channel and an outer ring stir-frying steam outlet channel. The air inlet of the inner ring stir-frying steam outlet channel is connected to the air inlet of the outer ring stir-frying steam outlet channel. The air outlet of the inner ring stir-frying steam outlet channel is connected to the air inlet of the second inner ring channel. The air outlet of the outer ring stir-frying steam outlet channel is connected to the air inlet of the second outer ring channel.

[0011] In this solution, two gas outlet channels are used to jointly transmit the gas for stir-frying, which can improve the propagation efficiency of the gas for stir-frying, thereby improving the efficiency and effect of stir-frying.

[0012] Preferably, the stir-fry valve includes a stir-fry valve body and a stir-fry valve core. The stir-fry valve body is provided with a stir-fry air inlet channel, an inner ring stir-fry air outlet channel, an outer ring stir-fry air outlet channel, a stir-fry valve cavity, and a stir-fry air outlet main channel. The stir-fry valve core is disposed in the stir-fry valve cavity. The stir-fry valve core can move relative to the stir-fry valve body to open or close the air outlet of the stir-fry valve core.

[0013] The air inlet of the stir-fry valve chamber is connected to the stir-fry air inlet channel, and the air outlet of the stir-fry valve chamber is connected to the air inlet of the stir-fry main air outlet. The stir-fry main air outlet has a first inner ring air outlet and a first outer ring air outlet. The first inner ring air outlet is connected to the air inlet of the inner ring stir-fry air outlet channel, and the first outer ring air outlet is connected to the air inlet of the outer ring stir-fry air outlet channel.

[0014] In this scheme, the air inlet of the inner ring stir-fry air outlet channel and the air inlet of the outer ring stir-fry air outlet channel are connected through the main air outlet channel of the stir-fry valve body, thereby realizing the connection between the second inner ring channel and the second outer ring channel.

[0015] Preferably, the nozzle mounting base further includes a connecting channel, the air inlet of the connecting channel being connected to the air outlet of the stir-frying air outlet channel, the connecting channel having a second inner ring air outlet and a second outer ring air outlet, the second inner ring air outlet being connected to the air inlet of the second inner ring channel, and the second outer ring air outlet being connected to the air inlet of the second outer ring channel.

[0016] In this solution, the second inner ring channel and the second outer ring channel are connected inside the nozzle mounting seat through a connecting channel.

[0017] Preferably, the connecting channel is disposed between the second inner ring channel and the second outer ring channel in an extension direction perpendicular to the second inner ring channel.

[0018] In this scheme, the above-mentioned arrangement ensures that the paths of the gas used for stir-frying in the inner and outer rings are similar as they flow from the connecting channel into the corresponding second inner ring channel or second outer ring channel, thus guaranteeing the uniformity of the heat distribution between the inner and outer rings.

[0019] Preferably, the second inner ring channel and the second outer ring channel are symmetrical about the connecting channel in the extending direction of the second inner ring channel.

[0020] In this scheme, the above settings ensure that the combustion gases from the inner and outer rings flow into the corresponding second inner ring channel or second outer ring channel via the connecting channel in the same way, thus guaranteeing the uniformity of the heat distribution between the inner and outer rings.

[0021] Preferably, the second inner ring channel and the second outer ring channel are disposed between the first inner ring channel and the first outer ring channel in an extension direction perpendicular to the second inner ring channel.

[0022] In this solution, the above-mentioned settings can shorten the flow path of the gas used for stir-frying and improve the efficiency of stir-frying.

[0023] Preferably, the nozzle mounting base further includes an inner ring connecting the main road and an outer ring connecting the main road;

[0024] The outlet of the first inner ring channel and the outlet of the second inner ring channel are both connected to the inlet of the inner ring connecting main road. The outlet of the inner ring connecting main road is provided with an inner ring main nozzle, which can inject gas toward the inner ring ejector tube.

[0025] The outlets of the first outer ring channel and the second outer ring channel are both connected to the inlet of the outer ring connecting main road. The outlet of the outer ring connecting main road is provided with an outer ring main nozzle, which can inject gas toward the outer ring ejector tube.

[0026] In this design, the inner ring connects to the main path, collecting the gas from the first and second inner ring channels. Therefore, only one main inner ring nozzle is needed to inject the gas from the first and second inner ring channels into the inner ring injector. Similarly, the outer ring connects to the main path, collecting the gas from the first and second outer ring channels. Therefore, only one main outer ring nozzle is needed to inject the gas outside the first and second outer ring channels into the outer ring injector. Both the inner and outer ring stir-fry gas are intercepted through corresponding nozzles, increasing the load on both rings to a smaller range of stir-fry heat, thus improving the stir-frying experience. Using the same nozzle to intercept both stir-fry gas and normal cooking gas improves the consistency of the stir-fry heat.

[0027] Preferably, the first inner ring channel and the second outer ring channel are independent of each other. The air outlet of the first inner ring channel is provided with a first inner ring nozzle, and the air outlet of the second inner ring channel is provided with a second inner ring nozzle. The projections of the first inner ring nozzle and the second inner ring nozzle on the inner ring ejector tube along the extension direction of the second inner ring channel both fall into the channel of the inner ring ejector tube.

[0028] The first outer ring channel and the second outer ring channel are independent of each other. The air outlet of the first outer ring channel is provided with a first outer ring nozzle, and the air outlet of the second outer ring channel is provided with a second outer ring nozzle. The projections of the first outer ring nozzle and the second outer ring nozzle on the outer ring ejector tube along the extension direction of the second outer ring channel both fall into the channel of the outer ring ejector tube.

[0029] In this design, the above setup ensures that the first inner ring channel and the first outer ring channel are not connected without opening the stir-fry valve, allowing the inner ring flame to ignite independently and increasing the range of heat adjustment. Both the inner and outer ring stir-fry gas are intercepted through corresponding nozzles, increasing the load on both rings to a smaller range of stir-fry heat, thus improving the stir-frying experience.

[0030] Preferably, the plug valve includes a plug valve body, a solenoid valve assembly, and a stopper. The plug valve body includes a gas intake passage, a first valve chamber, a second valve chamber, and a third valve chamber. The solenoid valve assembly is disposed in the first valve chamber, and the stopper is disposed in the second valve chamber. The second valve chamber and the third valve chamber are independent of each other.

[0031] The air inlet of the first valve chamber is connected to the gas intake channel, the air inlets of the second valve chamber and the third valve chamber are both connected to the air outlet of the first valve chamber, the air inlet of the inner ring gas channel and the air inlet of the outer ring gas channel are both connected to the air outlet of the second valve chamber, and the air outlet of the third valve chamber is connected to the air inlet of the stir-frying gas channel.

[0032] In this design, the third valve chamber of the stir-fry valve is positioned after the gas flows out of the first valve chamber and before it flows into the second valve chamber. On one hand, when the stove is not in use, the solenoid valve assembly and the valve core of the stir-fry valve can achieve two-point sealing of the gas flow, preventing gas leakage and providing better gas tightness and safety. On the other hand, the gas flowing into the stir-fry valve is not restricted by the valve stem, ensuring sufficient gas flow and enhancing the stir-frying experience.

[0033] The significant advantages of this invention are as follows: the second inner ring channel provides gas for stir-frying, and the second outer ring channel provides gas for stir-frying. The connection between the second inner and outer ring channels enables communication between the inner and outer rings, allowing gas originally intended for the inner ring to be supplied to the outer ring, and vice versa. This results in a more even distribution of gas between the inner and outer rings, leading to more uniform heating of the cookware and improved stir-frying performance. Attached Figure Description

[0089] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0090] Example 1

[0091] like Figures 1-3 As shown, this embodiment discloses a stove, including a stove panel 1, a burner cap, a stopcock valve 3, and a high-powered stir-fry valve 4. The gas outlets of both the stopcock valve 3 and the high-powered stir-fry valve 4 are connected to the burner cap, and are used to supply gas to the burner cap. The stopcock valve 3 controls the gas flow into the stove and can adjust the gas flow rate according to the user's needs to adjust the flame size at the burner cap. The high-powered stir-fry valve 4 increases the gas flow at the burner cap to enlarge the flame, enabling a high-powered stir-fry mode during cooking.

[0092] Specifically, such as Figure 1 and Figure 2 As shown, the burner cap is installed above the cooktop panel 1 to generate a flame. The burner cap includes an inner ring burner cap 21 and an outer ring burner cap 22, with the outer ring burner cap 22 fitted radially outside the inner ring burner cap 21.

[0093] like Figures 4-7 As shown, the plug valve 3 includes a plug valve body 31, a solenoid valve assembly 32, and a stop valve 33.

[0094] like Figures 4-7 As shown, the valve body 31 of the plug valve includes a gas inlet passage 311, an inner ring gas passage 312, an outer ring gas passage 313, a stir-fry gas passage 314, a first valve chamber 315, a second valve chamber 316, and a third valve chamber 317. The inlet of the first valve chamber 315 is connected to the gas inlet passage 311. The inlets of the second valve chamber 316 and the third valve chamber 317 are both connected to the outlet of the first valve chamber 315. The inlet of the inner ring gas passage 312 is connected to the inner ring outlet of the second valve chamber 316. The inlet of the outer ring gas passage 313 is connected to the outer ring outlet of the second valve chamber 316. The outlet of the third valve chamber 317 is connected to the inlet of the stir-fry gas passage 314. The second valve chamber 316 and the third valve chamber 317 are independent of each other.

[0095] like Figure 5 As shown, the solenoid valve assembly 32 is disposed within the first valve chamber 315 and is used to control the opening or closing of the gas outlet of the first valve chamber 315. When the gas outlet of the first valve chamber 315 is open, the gas in the first valve chamber 315 can flow to the second valve chamber 316 and the third valve chamber 317. When the gas outlet of the first valve chamber 315 is closed, the gas in the first valve chamber 315 cannot flow to the second valve chamber 316 and the third valve chamber 317.

[0096] like Figure 6 As shown, the shut-off valve 33 is disposed within the second valve chamber 316. The shut-off valve 33 controls the opening and closing of the inner and outer ring outlets of the second valve chamber 316, thereby controlling the amount of gas flowing from the second valve chamber 316 to the burner cap, and thus controlling the flame size at the burner cap. The shut-off valve 33 can control the opening of only the inner ring outlet of the second valve chamber 316 or simultaneously open both the inner and outer ring outlets of the second valve chamber 316.

[0097] It should be noted that the specific structure of the solenoid valve assembly 32, the specific structure of the gate valve 33, and the connection and communication method between the solenoid valve assembly 32 and the gate valve 33 are all existing technologies in this field and will not be described in detail here.

[0098] In this embodiment, the third valve chamber 317 of the stir-fry valve 4 is located after the gas flows out of the first valve chamber 315 and before it flows into the second valve chamber 316. On the one hand, when the stove is not in use, the solenoid valve assembly 32 and the stir-fry valve core 42 of the stir-fry valve 4 can achieve two-point sealing of the gas flow, preventing gas leakage and improving gas tightness and safety. On the other hand, the gas flowing into the stir-fry valve 4 is not restricted by the stopcock 33, ensuring sufficient gas flow into the stir-fry valve 4 and improving the stir-frying experience.

[0099] like Figure 8 and Figure 9As shown, the stir-fry valve 4 includes a stir-fry valve body 41 and a stir-fry valve core 42. The stir-fry valve body 41 has a stir-fry air inlet channel 411, a stir-fry air outlet channel 412, and a stir-fry valve cavity 415 inside. The stir-fry valve core 42 is located in the stir-fry valve cavity 415 and can move relative to the stir-fry valve body 41 to open or close the air outlet of the stir-fry valve core 42. Specifically, the stir-fry valve body 41 also has a stir-fry air outlet main channel 416 inside, and the stir-fry air outlet channel 412 includes an inner ring stir-fry air outlet channel 413 and an outer ring stir-fry air outlet channel 414. The air inlet of the stir-fry air intake channel 411 is connected to the air outlet of the stir-fry gas channel 314. The air inlet of the stir-fry valve chamber 415 is connected to the air outlet of the stir-fry air intake channel 411. The air outlet of the stir-fry valve chamber 415 is connected to the air inlet of the stir-fry main exhaust channel 416. The stir-fry main exhaust channel 416 has a first inner ring air outlet and a first outer ring air outlet. The first inner ring air outlet is connected to the air inlet of the inner ring stir-fry exhaust channel 413. The first outer ring air outlet is connected to the air inlet of the outer ring stir-fry exhaust channel 414.

[0100] In this embodiment, the air inlet of the inner ring stir-fry air outlet channel 413 and the air inlet of the outer ring stir-fry air outlet channel 414 are connected inside the stir-fry valve body 41 through the stir-fry main air outlet channel 416. That is, no matter whether the stir-fry valve 4 is in the open or closed state, the inner ring stir-fry air outlet channel 413 and the outer ring stir-fry air outlet channel 414 are always connected to each other.

[0101] like Figure 2 , Figure 3 , Figure 10 and Figure 11 As shown, the stove also includes a nozzle mounting base 5, an inner ring injector tube 61, and an outer ring injector tube 62. The inner ring injector tube 61 is connected to the inner ring burner cap 21, and the inner ring stir-fry gas in the inner ring gas passage 312 and the stir-fry gas passage 314 flows to the inner ring burner cap 21 through the inner ring injector tube 61. The outer ring injector tube 62 is connected to the outer ring burner cap 22, and the outer ring stir-fry gas in the outer ring gas passage 313 and the stir-fry gas passage 314 flows to the outer ring burner cap 22 through the outer ring injector tube 62.

[0102] like Figure 11As shown, the nozzle mounting base 5 includes a first inner ring channel 51, a second inner ring channel 52, a first outer ring channel 53, and a second outer ring channel 54. The air inlet of the first inner ring channel 51 is connected to the air outlet of the inner ring gas channel 312; the air inlet of the second inner ring channel 52 is connected to the air outlet of the inner ring stir-fry gas channel 413; the air inlet of the first outer ring channel 53 is connected to the air outlet of the outer ring gas channel 313; and the air inlet of the second outer ring channel 54 is connected to the air outlet of the outer ring stir-fry gas channel 414. The air outlets of the first inner ring channel 51 and the second inner ring channel 52 are both connected to the inner ring injector 61, and the air outlets of the first outer ring channel 53 and the second outer ring channel 54 are both connected to the outer ring injector 62.

[0103] Specifically, such as Figure 11 As shown, the nozzle mounting base 5 also includes an inner ring connecting main road 55 and an outer ring connecting main road 56. The outlets of the first inner ring channel 51 and the second inner ring channel 52 are both connected to the inlet of the inner ring connecting main road 55. The outlet of the inner ring connecting main road 55 is equipped with an inner ring main nozzle 71, which can inject gas towards the inner ring ejector tube 61. The outlets of the first outer ring channel 53 and the second outer ring channel 54 are both connected to the inlet of the outer ring connecting main road 56. The outlet of the outer ring connecting main road 56 is equipped with an outer ring main nozzle 72, which can inject gas towards the outer ring ejector tube 62.

[0104] In other alternative embodiments, the first inner ring channel 51 and the second inner ring channel 52 can be two independent channels, each with an inner ring nozzle at its outlet to inject the inner ring gas into the same inner ring injector 61. The first outer ring channel 53 and the second outer ring channel 54 can be two independent channels, each with an outer ring nozzle at its outlet to inject the outer ring gas into the same outer ring injector 62.

[0105] In this embodiment, the second inner ring channel 52 is used to provide stir-fry gas to the inner ring, and the second outer ring channel 54 is used to provide stir-fry gas to the outer ring. Since the inner ring stir-fry gas outlet channel 413 and the outer ring stir-fry gas outlet channel 414 are interconnected, the second inner ring channel 52, which is connected to the inner ring stir-fry gas outlet channel 413, and the second outer ring channel 54, which is connected to the outer ring stir-fry gas outlet channel 414, are also interconnected. This achieves the connection between the inner and outer rings of stir-fry gas, so that the stir-fry gas originally supplied to the inner ring can be supplied to the outer ring, and the stir-fry gas originally supplied to the outer ring can also be supplied to the inner ring, achieving a uniform distribution of stir-fry gas between the inner and outer rings, making the cookware heat more evenly and improving the stir-frying effect.

[0106] In this embodiment, the gas for stir-frying is transmitted through two stir-frying gas outlet channels 412 (inner ring stir-frying gas outlet channel 413 and outer ring stir-frying gas outlet channel 414), which can improve the propagation efficiency of the stir-frying gas and improve the efficiency and effect of stir-frying.

[0107] In this embodiment, the inner ring connecting main road 55 collects the gas from the first inner ring channel 51 and the second inner ring channel 52, so only one inner ring main nozzle 71 is needed to inject the gas from the first inner ring channel 51 and the second inner ring channel 52 into the inner ring ejector tube 61. The outer ring connecting main road 56 collects the gas from the first outer ring channel 53 and the second outer ring channel 54, so only one outer ring main nozzle 72 is needed to inject the gas from outside the first outer ring channel 53 and the second outer ring channel 54 into the outer ring ejector tube 62.

[0108] Both the inner and outer ring stir-fry gas are controlled through corresponding nozzles, increasing the load on both rings to a smaller range of stir-fry heat, thus improving the stir-frying experience. The stir-fry gas and normal cooking gas are controlled through the same nozzle, reducing the variation range of the inner ring flow, outer ring flow, and the total flow of both rings, thereby improving the consistency of the stir-fry heat.

[0109] Example 2

[0110] The stove in this embodiment is basically the same as that in embodiment 1, except that the structure of the stir-fry valve 4 and the nozzle mounting base 5 are different.

[0111] like Figures 12-15 As shown, the stir-fry valve 4 in this embodiment includes only one stir-fry steam outlet channel 412, and the second inner ring channel 52 and the second outer ring channel 54 are interconnected inside the nozzle connector.

[0112] Specifically, such as Figures 12-15 As shown, the nozzle mounting base 5 also includes a connecting channel 57. The air outlet of the stir-fry air intake channel 411 is connected to the air inlet of the stir-fry air outlet channel 412, and the air inlet of the connecting channel 57 is connected to the air outlet of the stir-fry air outlet channel 412. The connecting channel 57 has a second inner ring air outlet and a second outer ring air outlet. The second inner ring air outlet is connected to the air inlet of the second inner ring channel 52, and the second outer ring air outlet is connected to the air inlet of the second outer ring channel 54. In this embodiment, the connection between the second inner ring channel 52 and the second outer ring channel 54 is achieved inside the nozzle mounting base 5 through the connecting channel 57.

[0113] Furthermore, such as Figure 14 and Figure 15As shown, the connecting channel 57 is located between the second inner ring channel 52 and the second outer ring channel 54 in an extension direction perpendicular to the second inner ring channel 52. Specifically, the second inner ring channel 52 and the second outer ring channel 54 are symmetrical about the connecting channel 57 in the extension direction of the second inner ring channel 52, so that the combustion gas from the inner and outer rings flows into the corresponding second inner ring channel 52 or second outer ring channel 54 through the connecting channel 57 along the same path, ensuring the uniformity of the fire distribution between the inner and outer rings.

[0114] In other alternative implementations, the second inner ring channel 52 and the second outer ring channel 54 may not be designed to be symmetrical about the connecting channel 57. The similar travel distance from the connecting channel 57 to the second inner ring channel 52 and the second outer ring channel 54 can also ensure the uniformity of the inner and outer ring fire distribution.

[0115] Furthermore, such as Figure 14 and Figure 15 As shown, in this embodiment, the second inner ring channel 52 and the second outer ring channel 54 are arranged between the first inner ring channel 51 and the first outer ring channel 53 in an extension direction perpendicular to the second inner ring channel 52, thereby shortening the flow path of the stir-frying gas and improving the stir-frying efficiency.

[0116] In other alternative implementations, the connecting channel 57 may also be located on the side of the first inner ring channel 51 or the first outer ring channel 53 away from the first outer ring channel 53 or the first inner ring channel 51.

[0117] like Figure 15 As shown, in this embodiment, the first inner ring channel 51 and the second outer ring channel 54 are independent of each other. The outlet of the first inner ring channel 51 is provided with a first inner ring nozzle 73, and the outlet of the second inner ring channel 52 is provided with a second inner ring nozzle 74. The projections of the first inner ring nozzle 73 and the second inner ring nozzle 74 along the extension direction of the second inner ring channel 52 onto the inner ring ejector tube 61 both fall into the channel of the inner ring ejector tube 61. That is, the gas in the first inner ring channel 51 is injected into the inner ring ejector tube 61 through the first inner ring nozzle 73, and the gas in the second inner ring channel 52 is injected into the same inner ring ejector tube 61 through the second inner ring nozzle 74. The first outer ring channel 53 and the second outer ring channel 54 are independent of each other. The outlet of the first outer ring channel 53 is provided with a first outer ring nozzle 75, and the outlet of the second outer ring channel 54 is provided with a second outer ring nozzle 76. The projections of the first outer ring nozzle 75 and the second outer ring nozzle 76 along the extension direction of the second outer ring channel 54 onto the outer ring ejector tube 62 both fall into the channel of the outer ring ejector tube 62. That is, the gas outside the first outer ring channel 53 is injected into the outer ring ejector tube 62 through the first outer ring nozzle 75, and the gas outside the second outer ring channel 54 is injected into the same outer ring ejector tube 62 through the second outer ring nozzle 76.

[0118] In this embodiment, both the inner and outer ring stir-fry gas are intercepted through corresponding nozzles, increasing the load on both rings to a smaller range of stir-fry heat, thus improving the stir-frying experience. Furthermore, without opening the stir-fry valve 4, the first inner ring channel 51 and the first outer ring channel 53 are not connected, allowing the inner ring flame to ignite independently and increasing the range of heat adjustment.

[0119] In other alternative embodiments, the first inner ring channel 51 and the second inner ring channel 52, and the first outer ring channel 53 and the second outer ring channel 54 may also be interconnected.

[0120] Furthermore, even when the high-heat cooking mode (i.e., no flame on the outer ring) is activated, the outer ring can still receive high-heat gas because the second inner ring channel 52 is connected to the second outer ring channel 54. This ignites the outer ring flame, quickly transitioning from low to high heat, improving stir-fry efficiency and enhancing the user experience. However, although the high-heat valve in this embodiment can be opened at any heat level, to further prevent excessive flow changes when the high-heat mode is activated, the timing of the high-heat valve 4's opening can be controlled. For example, it is recommended to activate the high-heat mode only when the stopcock 33 has rotated to a certain angle range.
