Abstract
Description
Technical Field
[0001] The utility model relates to the field of stoves, in particular to a fire cover and a stove comprising the same. Background Art
[0002] A common household burner generally has a fire cover, together with an ignition needle, a thermocouple (or an ion sensing needle with equivalent function) and other components to realize functions such as generating flame and maintaining flame. The ignition needle and the thermocouple are mainly arranged around the inner fire cover. An ignition hole and other fire outlet holes are provided on the fire cover. When the overflow liquid blocks the ignition hole, the gas stove cannot ignite. However, no manufacturer has made good improvements on the anti-blocking of the ignition hole in the prior art. During the cooking process of the user or when the user washes the pot and puts it back on the gas stove, the dripping water droplets can easily block the ignition hole, resulting in poor ignition. Moreover, the structural design of the ignition point of many fire covers is relatively simple. Basically, one ignition hole is designed in a targeted manner. The blockage of this fire hole or the flame separation of this fire hole will reduce the success rate of ignition. Therefore, it is necessary to further improve the structure of the inner fire cover. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defect that the liquid dripping on the cooker in the prior art easily blocks the ignition hole, and to provide a fire cover and a cooker including the same.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] A fire cover, comprising: a first guide channel, which is arranged on the top wall of the fire cover and communicated with the edge of the top wall of the fire cover, and is used to guide the liquid to be guided on the top surface of the fire cover to the outside of the fire cover; a second guide channel, which is arranged inside the fire cover, one end of the second guide channel is communicated with the top wall of the fire cover, and the other end passes through the fire cover, and is used to guide the liquid to be guided on the top surface of the fire cover to the inside of the second guide channel and flow to the outside of the fire cover.
[0006] By setting the first guide channel and the second guide channel, when liquid drips onto the fire cover, the first guide channel on the top wall and the second guide channel that runs through the fire cover both have a guiding effect on the liquid to be guided to avoid liquid accumulation. The scheme of setting the guide channels on the top wall and the inside of the fire cover at the same time can, on the one hand, speed up the guiding speed, and on the other hand, increase the guiding flow rate. During the cooking process, if the liquid boils excessively and overflows in large quantities and quickly flows onto the fire cover, the fire cover can quickly guide the large amount of overflowed liquid through the synergistic effect of the first guide channel and the second guide channel, thereby preventing the gas from diffusing into the air after the fire is turned off to cause a safety hazard, and also greatly reduces the possibility of the ignition hole being blocked by liquid and food mixed in the liquid.
[0007] Preferably, the fire cover comprises a fire cover body and a protective umbrella, wherein the fire cover body is provided with an ignition hole, and the protective umbrella is provided above the ignition hole and protrudes relative to the fire cover body along the radial direction of the fire cover body;
[0008] The second flow guiding channel comprises a liquid inlet, a flow guiding hole and a liquid outlet, wherein the liquid inlet is at least partially arranged on the top wall of the protective umbrella, the flow guiding hole communicates with the liquid inlet and the liquid outlet, and the liquid outlet is lower than the liquid inlet;
[0009] The projection of the liquid outlet on the horizontal plane does not overlap with the projection of the ignition hole on the horizontal plane.
[0010] By at least partially arranging the liquid inlet of the second guide channel on the protective umbrella, when liquid drips onto the protective umbrella, it can quickly flow into the liquid inlet to avoid liquid accumulation on the protective umbrella. At the same time, the projection of the liquid outlet on the horizontal plane and the projection of the ignition hole on the horizontal plane do not overlap at all, ensuring that the liquid discharged from the second channel will no longer flow into the ignition hole, preventing the ignition hole from being blocked, and reducing the occurrence of poor ignition of the fire cover.
[0011] Preferably, an overflow portion is provided in the second guide channel, and the overflow portion is provided at the top of the guide hole.
[0012] By arranging the overflow portion at the top of the guide hole, it can be used as a spare space for the overflow guide hole when there is a lot of liquid. When there is too much overflow and the guide hole cannot quickly discharge the liquid, the overflow portion can accommodate part of the liquid entering the guide hole, reducing the possibility of the liquid overflowing to the top surface of the eaves. The overflow portion is arranged at the top of the guide hole, and the position of the overflow portion is higher than the guide hole, which ensures that no liquid will flow into the overflow portion when the guide hole guides normally. When the guide hole does not need the accommodating function of the overflow portion, the liquid in the overflow portion can also quickly flow into the guide hole and then be discharged.
[0013] Preferably, the first flow guiding channel comprises a first flow guiding slope arranged on the top wall of the protective umbrella and the top wall of the fire cover body, and the first flow guiding slope is inclined toward the liquid inlet.
[0014] By arranging a diversion slope on the top surface of the protective umbrella, the flow of liquid toward the liquid inlet can be accelerated to avoid blockage of the ignition hole.
[0015] Preferably, the fire cover also includes a guide groove, which is arranged on a side opposite to the protective umbrella, and the guide groove protrudes relative to the fire cover body along the radial direction of the fire cover body. The first guide channel includes a second guide slope, and the second guide slope is arranged on the top wall of the guide groove. The second guide slope is arranged downwardly from the inside to the outside along the radial direction of the fire cover body.
[0016] By setting a guide groove protruding relative to the fire cover body and setting a second guide slope on the top wall of the guide groove, the liquid to be guided can flow to the outside of the fire cover through the guide groove, and the inclined second guide slope can accelerate the flow of the liquid to be guided.
[0017] Preferably, the second flow guide slope is lower than the edge of the top wall of the fire cover body.
[0018] By arranging the second flow guiding slope to be lower than the edge of the top wall of the fire cover body, it is beneficial for the liquid to be guided to flow into the second flow guiding slope.
[0019] Preferably, the liquid outlet is recessed inwardly relative to the side wall of the fire cover body, and a groove extending in a vertical direction is provided below the liquid outlet.
[0020] By arranging a groove extending in the vertical direction below the liquid outlet, the groove has a guiding effect on the liquid and prevents the liquid from diffusing in the circumferential direction.
[0021] Preferably, the edge of the protective umbrella is provided with a vertical edge protruding upward relative to the guide slope; and / or, the edge of the fire cover body is provided with a vertical edge protruding upward relative to the top wall.
[0022] By arranging the fire cover with an upwardly protruding vertical edge, the vertical edge can prevent liquid from dripping from the edge.
[0023] Preferably, a reinforcing component is arranged below the protective umbrella, and the reinforcing component is connected to the bottom surface of the protective umbrella and the side wall of the fire cover body. The radial thickness of the reinforcing component gradually decreases from top to bottom, and the outer wall surface of the reinforcing component is inclined from top to bottom toward the axis of the fire cover body.
[0024] By arranging a reinforcing component on the bottom surface of the protective umbrella, and the reinforcing component connecting the bottom surface of the protective umbrella and the side wall of the fire cover body, it is possible to prevent the protective umbrella from being deformed and warped due to continuous burning. The radial thickness of the reinforcing component is set to gradually decrease from top to bottom, and the outer wall surface of the reinforcing component is inclined inward from top to bottom. The radial thickness below the reinforcing component is thinner, and the impact on combustion is smaller.
[0025] A stove comprises the fire cover as described above.
[0026] The positive progressive effect of the present invention is that by setting the first guide channel and the second guide channel, when liquid drips onto the fire cover, the first guide channel on the top wall and the second guide channel that runs through the fire cover both have a guiding effect on the liquid to be guided, thereby avoiding liquid accumulation. The scheme of setting the guide channels on the top wall and the interior of the fire cover at the same time can, on the one hand, speed up the guiding speed, and on the other hand, increase the guiding flow rate. During the cooking process, if the liquid boils excessively, causing a large amount of overflow and quickly flows onto the fire cover, the fire cover can quickly guide the large amount of overflowed liquid through the synergistic effect of the first guide channel and the second guide channel, thereby preventing the gas from diffusing into the air after the fire is turned off, thereby causing a safety hazard, and also greatly reducing the possibility of the ignition hole being blocked by liquid and food mixed in the liquid.

[0049] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0050] like Figure 1-Figure 5 As shown, this embodiment provides a fire cover 100, which includes a first guide channel 001 and a second guide channel 002. Figure 1 and Figure 4 As shown, the first guide channel 001 is arranged on the top wall of the fire cover 100, and the first guide channel 001 is connected to the edge of the top wall of the fire cover 100, and is used to guide the liquid to be guided at the top surface of the fire cover 100 to the outside of the fire cover 100; the second guide channel 002 is arranged inside the fire cover 100, one end of the second guide channel 002 is connected to the top wall of the fire cover 100, and the other end passes through the fire cover 100, and the second guide channel 002 is used to guide the liquid to be guided at the top surface of the fire cover 100 to the inside of the second guide channel 002, and flow to the outside of the fire cover 100.
[0051] By setting the first guide channel 001 and the second guide channel 002, when liquid drips onto the fire cover 100, the first guide channel 001 on the top wall and the second guide channel 002 that runs through the fire cover 100 both have a guiding effect on the liquid to be guided to avoid liquid accumulation. The scheme of setting the guide channels on the top wall and the interior of the fire cover 100 at the same time can, on the one hand, speed up the guiding speed, and on the other hand, increase the guiding flow rate. During the cooking process, if the liquid boils excessively and overflows in large quantities and quickly flows onto the fire cover 100, the first guide channel 001 and the second guide channel 002 work together, and the fire cover 100 can quickly guide the large amount of overflowed liquid to prevent the gas from diffusing into the air after the fire is turned off, causing a safety hazard, and also greatly reduces the possibility of the ignition hole 11 being blocked by liquid and food mixed in the liquid, thereby avoiding the occurrence of poor ignition.
[0052] Specifically, if Figure 1 and Figure 4As shown, the diversion starting positions of the first diversion channel 001 and the second diversion channel 002 are both on the top wall of the fire cover 100. The first diversion channel 001 diverts the liquid to be diverted from the top wall of the fire cover 100 to the outside of the fire cover 100, while the second diversion channel 002 diverts the liquid to be diverted from the inside of the fire cover 100 to the outside of the fire cover 100. The two diversion channels work together to speed up the diversion speed and increase the diversion flow rate.
[0053] In this embodiment, the fire cover 100 includes a fire cover body 1, a protective umbrella 2 and a guide groove 3. An ignition hole 11 is provided on the fire cover body 1. The protective umbrella 2 is provided above the ignition hole 11 and protrudes relative to the fire cover body 1 along the radial direction of the fire cover body 1. The guide groove 3 is provided on the side opposite to the protective umbrella 2 and protrudes relative to the fire cover body 1 along the radial direction of the fire cover body 1. The second guide channel 002 includes a liquid inlet 201, a guide hole 202 and a liquid outlet 203. The liquid inlet 201 is provided on the top wall of the fire cover 100 and is partially provided on the top wall of the protective umbrella 2. The guide hole 202 connects the liquid inlet 201 and the liquid outlet 203. The height of the liquid outlet 203 is lower than the height of the liquid inlet 201, and the projection of the liquid outlet 203 on the horizontal plane does not overlap with the projection of the ignition hole 11 on the horizontal plane. By arranging part of the liquid inlet 201 of the second guide channel 002 on the protective umbrella 2, when liquid drops onto the protective umbrella 2, it can quickly flow into the liquid inlet 201 to avoid liquid accumulation on the protective umbrella 2. At the same time, the projection of the liquid outlet 203 on the horizontal plane does not overlap with the projection of the ignition hole 11 on the horizontal plane, ensuring that the liquid discharged from the second channel will no longer flow to the ignition hole 11, preventing the ignition hole 11 from being blocked, and reducing the occurrence of poor ignition of the fire cover 100.
[0054] Specifically, the liquid inlet 201 in this embodiment extends from the connection between the top wall of the protective umbrella 2 and the top wall of the fire cover body 1 toward the axis of the fire cover body 1. When the liquid to be diverted flows from the protective umbrella 2 to the fire cover body 1, it will flow into the second diversion channel 002 when flowing through the liquid inlet 201, and then be discharged outside the fire cover 100.
[0055] In other embodiments, the area occupied by the liquid inlet 201 on the top wall of the protective umbrella 2 can be appropriately increased, or the width of the liquid inlet 201 can be expanded along the circumference of the fire cover 100. When the width of the circumferential liquid inlet 201 along the fire cover 100 is expanded to be the same as the width of the protective umbrella 2, it can ensure that the liquid in the protective umbrella 2 flows into the second guide channel 002 and is guided outside the fire cover 100 while flowing toward the fire cover body 1.
[0056] In this embodiment, an overflow portion 204 is further provided at the top of the second diversion channel 002. The overflow portion 204 is provided inside the fire cover 100, and the height of the overflow portion 204 is higher than the height of the diversion hole 202. By providing the overflow portion 204 at the top of the diversion hole 202, it can be used as a spare space for the overflow diversion hole 202 when there is a lot of liquid. When there is too much overflow and the diversion hole 202 cannot quickly discharge the liquid, the overflow portion 204 can accommodate part of the liquid entering the diversion hole 202, reducing the possibility of the liquid overflowing to the top surface of the eaves. The overflow portion 204 is provided at the top of the diversion hole 202, and the position of the overflow portion 204 is higher than the diversion hole 202, ensuring that no liquid will flow into the overflow portion 204 when the diversion hole 202 is diverting normally. When the diversion hole 202 does not need the accommodation function of the overflow portion 204, the liquid in the overflow portion 204 can also quickly flow into the diversion hole 202 and then be discharged.
[0057] Specifically in this embodiment, the liquid inlet 201 of the second guide channel 002 is arranged near the protective umbrella 2, the liquid outlet 203 is arranged below the guide groove 3 on the side opposite to the protective umbrella 2, the guide hole 202 is arranged as a linear channel, and the overflow portion 204 is in the axial extension direction of the guide hole 202. The streamlines from the overflow portion 204 to the guide hole 202 or from the liquid inlet 201 to the liquid outlet 203 are all straight lines from top to bottom, with small flow resistance, which is conducive to rapid discharge of the fluid.
[0058] At the same time, if Figure 5 As shown, the liquid outlet 203 is recessed inwardly relative to the side wall of the fire cover body 1, and a groove 4 extending in the vertical direction is provided below the liquid outlet 203. By setting the liquid outlet 203 to be recessed inwardly relative to the side wall of the fire cover body 1, and providing the groove 4 below the liquid outlet 203, the liquid to be diverted flows out of the liquid outlet 203 and flows downwardly under the diversion effect of the groove 4, thereby preventing the liquid from diffusing in the circumferential direction.
[0059] like Figure 1 As shown, in the present embodiment, the first guide channel 001 includes a first guide slope 101 and a second guide slope 102, wherein the first guide slope 101 is arranged on the top wall of the protective umbrella 2, and the second guide slope 102 is arranged on the top wall of the guide groove 3, the first guide slope 101 is inclined to the liquid inlet 201, and the second guide slope 102 is inclined downward from the inside to the outside along the radial direction of the fire cover body 1, that is, in the present embodiment, the first guide channel 001 has two guide slopes, wherein the first guide slope 101 is used to guide the liquid to be guided to the liquid inlet 201 of the second guide channel 002, and the second guide slope 102 is used to directly guide the liquid to be guided from the top wall of the fire cover 100 to the outside of the fire cover 100, thereby accelerating the diversion speed of the liquid to be guided and increasing the diversion flow rate.
[0060] In other embodiments, the top wall of the fire cover body 1 may also be inclined toward the liquid inlet 201, which is conducive to the liquid to be diverted on the top wall of the fire cover 100 to flow quickly to the liquid inlet 201. Of course, in more embodiments, the top wall of the fire cover body 1 may also be inclined toward the guide groove 3, so that the liquid to be diverted on the top wall of the fire cover 100 is discharged from the second guide slope 102 to the outside of the fire cover 100, or the top wall of the fire cover 100 is set to be inclined toward the liquid inlet 201 near the protective umbrella 2, and inclined toward the guide groove 3 near the guide groove 3, which will not be repeated here.
[0061] Specifically, in this embodiment, the second guide slope 102 is lower than the edge of the top wall of the fire cover body 1, which is conducive to the liquid to be guided on the top wall of the fire cover 100 to flow to the second guide slope 102, while preventing the liquid to be guided on the second guide slope 102 from flowing back to the top wall of the fire cover body 1.
[0062] In this embodiment, the edges of the protective umbrella 2, the fire cover body 1 and the guide groove 3 are provided with a vertical edge 5 protruding upward relative to the top wall of the fire cover 100. The vertical edge 5 has a water-retaining function, which can prevent the liquid to be diverted from diffusing and dripping from the edge, thereby prompting the liquid to be diverted to leave the fire cover 100 from the first guide channel 001 and the second guide channel 002.
[0063] Of course, in other embodiments, the edges of the protective umbrella 2 and the guide groove 3 may not be provided with the vertical edge 5. The inclination direction of the first guide slope 101 and the second guide slope 102 can guide the flow of the liquid to be guided, and to a certain extent avoid the liquid to be guided from dripping disorderly from the edge.
[0064] like Figure 2 and Figure 3 As shown, in the present embodiment, a reinforcing component 6 is further provided below the protective umbrella 2, and the reinforcing component 6 connects the bottom surface of the protective umbrella 2 and the side wall of the fire cover body 1, the radial thickness of the reinforcing component 6 gradually decreases from top to bottom, and the outer wall surface of the reinforcing component 6 is inclined from top to bottom toward the axis of the fire cover body 1, and the bottom surface of the protective umbrella 2 and the side wall of the fire cover body 1 are connected by the reinforcing component 6, so that the deformation and warping of the protective umbrella 2 caused by continuous burning can be prevented, and the radial thickness of the reinforcing component 6 is set to gradually decrease from top to bottom, and the outer wall surface of the reinforcing component 6 is inclined inward from top to bottom, and the radial thickness below the reinforcing component 6 is thinner, does not block the ignition hole 11, and has less effect on combustion.
[0065] This embodiment further provides a stove, which includes the fire cover 100 as described above. By arranging the fire cover as described above in the stove, the stove has good ignition ability and anti-blocking ability.
