[0002] With the healthy development of my country's kitchen appliance industry, users' requirements for household stoves are not limited to the rigid demand for cooking, and their requirements for appearance, stability, ease of use, etc. are gradually increasing. Existing gas stoves usually use two fire covers, inner and outer rings, in conjunction with components such as ignition pins to achieve functions such as generating flames and maintaining flames.

[0003] However, there is water and oil from the bottom of the pot on the surface of the inner ring fire cover of the existing inner and outer ring fire covers. Liquids such as water and oil can easily block the gas ignition holes on the peripheral wall of the inner fire cover. When the gas ignition holes are blocked, it will prevent the gas from spraying out normally from the gas ignition holes. The ignition needle cannot contact the gas when discharging, causing the stove to fail to ignite.

[0004] For this reason, it is necessary to propose a cooking stove to solve the above problems. Utility Model Content

[0045] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art fall within the scope defined by the claims attached to this application.

[0046] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] The applicant found that when water or oil from the bottom of the pot drips onto the surface of the inner fire cover and accumulates to a certain extent to break through the surface tension, the water or oil will flow in any direction along the inner fire cover and may be diverted to the ignition hole, causing the ignition hole to be blocked.

[0049] The utility model provides a stove which can effectively prevent the gas ignition hole dripping on the inner fire cover from being blocked by liquid (the liquid can specifically include water, oil, or a mixture of oil and water), thereby ensuring the success rate of ignition of the stove.

[0050] Please refer to Figures 1 to 6In the embodiment of the present application specification, a stove is provided, which may include: a burner head 1, an inner fire cover 2, an outer fire cover 3 and an ignition needle 4, the burner head 1 has an inner gas outlet 11 and an outer gas outlet 12, the inner fire cover 2 is covered on the inner gas outlet 11, and the outer fire cover 3 is covered on the outer gas outlet 12; the inner fire cover 2 includes: a cover body, the cover body includes a top cover 21 and a peripheral wall 22 located below the top cover 21, a gas ignition hole 221 for ignition is opened on the peripheral wall 22, and the gas ejected from the gas ignition hole 221 can be ignited by the ignition needle 4; the periphery of the top cover 21 is provided with a waterproof part 211 and a water guide part 212, the waterproof part 211 is located above the ignition needle 4 and the gas ignition hole 221, and at least one side of the waterproof part 211 is provided with the water guide part 212, and the water guide part 212 is used to guide the liquid on the top cover 21 to a direction away from the gas ignition hole 221.

[0051] In the embodiment of the present application, the stove may mainly include: a burner head 1, an inner fire cover 2, an outer fire cover 3 and an ignition needle 4. The burner head 1 has an inner gas outlet 11 and an outer gas outlet 12. The inner fire cover 2 is covered on the inner gas outlet 11, and the inner gas outlet 11 is connected to the inner gas ejection pipe. The gas flowing in from the inner gas ejection pipe can flow out through the inner gas outlet 11 and then be ejected from the hole opened on the inner fire cover 2. The outer fire cover 3 is covered on the outer gas outlet 12, and the outer gas outlet 12 is connected to the outer ring gas ejection pipe. The gas flowing in from the outer gas ejection pipe can flow out through the outer gas outlet 12 and then be ejected from the hole opened on the outer fire cover 3.

[0052] The inner fire cover 2 includes a cover body. The cover body includes a top cover 21 and a peripheral wall 22 located below the top cover 21. Figure 2 or Figure 6 , wherein a gas ignition hole 221 for ignition is provided on the peripheral wall 22. The gas ejected from the gas ignition hole 221 can be ignited by the ignition needle 4. Specifically, the number of the gas ignition holes 221 can be one, or multiple, such as two. When the number of the gas ignition holes 221 is multiple, the multiple gas ignition holes 221 can be spaced apart along the circumferential direction of the peripheral wall 22. The gas ignition hole 221 is matched with the position of the ignition needle 4 to ensure that when the ignition needle 4 ignites, the electric spark released can ignite the gas at the gas ignition hole 221. A flame hole 222 can also be provided on the peripheral wall 22. The number of the flame holes 222 can be multiple, and the multiple flame holes 222 can be evenly spaced apart along the circumferential direction of the periphery.

[0053] The periphery of the top cover 21 has a waterproof portion 211. The waterproof portion 211 is located above the ignition needle 4 and the gas ignition hole 221. The waterproof portion 211 is used to cover the ignition needle 4 and the gas ignition hole 221. The waterproof portion 211 can be a waterproof eave protruding from the top cover 21, and the downward projection of the waterproof eave can at least cover the ignition needle 4. In addition, in the circumferential direction, the boundaries on both sides of the waterproof eave can also cover the gas ignition hole 221, so as to prevent the droplets on the top cover 21 from flowing vertically downward directly into the gas ignition hole 221 to a certain extent.

[0054] However, the applicant further discovered that: even if the above-mentioned waterproof portion 211 is provided, in some cases, the liquid droplets on the top cover 21 will still bypass the waterproof eaves and flow from at least one side of the waterproof eaves or through the lower surface of the waterproof eaves to the gas ignition hole 221, causing the gas ignition hole 221 to be blocked.

[0055] In order to more effectively prevent the gas ignition holes on the inner fire cover 2 from being blocked and to more reliably ensure the ignition success rate, the present application provides a water guide portion 212 on the periphery of the top cover 21, close to the waterproof portion 211. The water guide portion 212 can be used to guide the liquid on the top cover 21 in a direction away from the gas ignition hole 221 through the surface tension of the liquid, thereby more effectively preventing the gas ignition holes on the inner fire cover 2 from being blocked and to more reliably ensure the ignition success rate.

[0056] The water diversion part 212 may be disposed on any side close to the waterproof part 211 . Preferably, the water diversion part 212 is disposed on both sides of the waterproof part 211 .

[0057] When the water guide part 212 is respectively arranged on both sides of the waterproof part 211, when liquid is stored on the top cover, even if the liquid flows from both sides of the waterproof part 211, the water guide parts 212 on both sides can be used to guide the liquid to both sides of the waterproof part 211 to a position away from the gas ignition hole 221 through the surface tension of the liquid, thereby further improving the reliability of the guidance.

[0058] In this embodiment, the water diversion portion 212 can be a convex structure provided on the periphery of the top cover 21. Specifically, the outer contour of the convex structure can be an arc shape as a whole, or can be a structure in which a straight line and a circular arc are matched, or can also be a structure in which multiple straight lines are matched, etc. Of course, the construction method of the convex structure can also be other methods, and is not limited to the above description. Under the inspiration of the technical essence of this application, technicians in the relevant field may also make other changes, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the protection scope of this application.

[0059] In one embodiment, the water guide portion 212 is an arc-shaped protrusion. Specifically, the arc-shaped protrusion is semicircular or quasi-semicircular.

[0060] When the water guide portion 212 is an arc-shaped protrusion formed on the periphery of the top cover 21, the arc-shaped protrusion can guide the liquid more smoothly and more smoothly than protrusions of other shapes when the liquid droplets are directed away from the waterproof portion 211, thereby achieving a better diversion effect. In addition, when the water guide portion 212 is an arc-shaped protrusion, specifically a semicircular or semi-elliptical shape, since the corners are all arc-shaped structures without sharp angle structures, the safety of the user when cleaning the cooker can also be guaranteed.

[0061] In order to ensure that the water guide portion 212 can reliably guide the liquid droplets on the top cover 21 close to the waterproof portion 211 or at the waterproof portion 211 , the water guide portion 212 is disposed close to the waterproof portion 211 .

[0062] The size between the edge of the water diversion portion 212 close to the waterproof portion 211 and the edge of the waterproof portion 211 close to the water diversion portion 212 needs to meet certain requirements.

[0063] Specifically, the distance between the edge of the water diversion portion 212 close to the waterproof portion 211 and the edge of the waterproof portion 211 close to the water diversion portion 212 is 2 mm to 5 mm.

[0064] Taking into account that the droplets themselves also have a certain size, generally speaking, the radial size of the droplets is between 2 mm and 3 mm. When the droplets flow between the water guide portion 212 and the waterproof portion 211, since the distance between the two is not less than 2 mm, for droplets of larger sizes, the problem of being unable to effectively guide part of the liquid due to too small a spacing can be effectively avoided. Moreover, since the distance between the two is not greater than 5 mm, it can be ensured that the water guide portion 212 can effectively use the tension of the liquid for guidance, avoiding the problem of being unable to use the tension of the liquid for guidance due to too large a spacing.

[0065] Of course, the embodiment of the present application does not exclude the case where the minimum value of the distance between the edge of the water diversion part 212 close to the waterproof part 211 and the edge of the waterproof part 211 close to the water diversion part 212 is slightly less than 2 mm. For example, the minimum value of the distance between the edge of the water diversion part 212 close to the waterproof part 211 and the edge of the waterproof part 211 close to the water diversion part 212 can be 1.9 mm, 1.8 mm, etc. When the distance between the edge of the water diversion part 212 close to the waterproof part 211 and the edge of the waterproof part 211 close to the water diversion part 212 is slightly less than 2 mm, it can also achieve the same effect as the minimum boundary value (2 mm) in guiding the liquid.

[0066] Similarly, the embodiments of the present application do not exclude the case where the maximum value of the distance between the edge of the water diversion portion 212 close to the waterproof portion 211 and the edge of the waterproof portion 211 close to the water diversion portion 212 is slightly greater than 5 mm. For example, the maximum value of the distance between the edge of the water diversion portion 212 close to the waterproof portion 211 and the edge of the waterproof portion 211 close to the water diversion portion 212 may be 5.1 mm, 5.2 mm, etc. When the distance between the edge of the water diversion portion 212 close to the waterproof portion 211 and the edge of the waterproof portion 211 close to the water diversion portion 212 is slightly greater than 5 mm, the guiding effect on the liquid can also achieve an effect that is substantially the same as the maximum boundary value (5 mm).

[0067] Of course, the above distance range is mainly determined based on the size corresponding to the current conventional size of stoves used in households. In some cases, for example, when the specifications of the stove itself change, the distance between the edge of the water inlet portion 212 close to the waterproof portion 211 and the edge of the waterproof portion 211 close to the water inlet portion 212 can also be adaptively adjusted.

[0068] Alternatively, the central angle between the middle of the water diversion portion 212 and the middle of the waterproof portion 211 is not less than 20° and not more than 30°. Considering that the droplet itself also has a certain size, generally speaking, the radial size of the droplet is between 2 mm and 3 mm, and for a general top cover, its circumferential size is within a certain fixed range. When the central angle between the middle of the water diversion portion 212 and the middle of the waterproof portion 211 is not less than 20° and not more than 30°, correspondingly, the arc length of the spacing or interval between the water diversion portion 212 and the waterproof portion 211 is a relatively fixed range.

[0069] When liquid droplets flow between the water diversion portion 212 and the waterproof portion 211, since the central angle between the middle portion of the water diversion portion 212 and the middle portion of the waterproof portion is not less than 20°, the problem of being unable to effectively guide part of the liquid due to too small a spacing can be effectively avoided for liquid droplets of larger sizes. Moreover, since the central angle between the middle portion of the water diversion portion 212 and the middle portion of the waterproof portion is not greater than 30°, it can be ensured that the water diversion portion 212 can effectively use the tension of the liquid for guidance, thus avoiding the problem of being unable to use the tension of the liquid for guidance due to too large a spacing.

[0070] Of course, the embodiment of the present application does not exclude the situation that the minimum value of the central angle between the middle of the water diversion part 212 and the middle of the waterproof part 211 is slightly less than 20°. For example, the minimum value of the central angle between the middle of the water diversion part 212 and the middle of the waterproof part 211 can be 19°, 18°, etc. When the minimum value of the central angle between the middle of the water diversion part 212 and the middle of the waterproof part 211 is a value slightly less than 20°, it can also achieve the same effect as the minimum boundary value (20°) in guiding the liquid.

[0071] Similarly, the embodiment of the present application does not exclude the case where the maximum value of the central angle between the middle of the water diversion portion 212 and the middle of the waterproof portion 211 is slightly greater than 30°. For example, the maximum value of the central angle between the middle of the water diversion portion 212 and the middle of the waterproof portion 211 may be 31°, 32°, etc. When the maximum value of the central angle between the middle of the water diversion portion 212 and the middle of the waterproof portion 211 is slightly greater than 30°, it can also achieve the same effect as the maximum boundary value (30°) in guiding the liquid.

[0072] Alternatively, the ratio of the arc length between the edge of the water diversion portion 212 close to the waterproof portion 211 and the edge of the waterproof portion 211 close to the water diversion portion 212 to the circumference of the circle where the arc length lies is not greater than 1 / 12. When the above arc length ratio requirement is met, the problem of being unable to use the tension of the liquid for diversion due to the large spacing can also be avoided.

[0073] In one embodiment, the water guide portion 212, the waterproof portion 211, the top cover 21, and the peripheral wall 22 are integrally formed.

[0074] In this embodiment, the water diversion part 212, the waterproof part 211, the top cover 21, and the peripheral wall 22 can be integrally formed. The integral forming method can be casting. Of course, the integral forming method can also be other methods, not limited to the above description. The technicians in the relevant field may make other changes under the inspiration of the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be included in the protection scope of this application.

[0075] When the water diversion part 212, the waterproof part 211, the top cover 21, and the surrounding wall 22 are integrally formed, multiple detailed structures with requirements on size, structure, and relative position can be processed and formed at one time, which not only saves costs but also helps to ensure processing accuracy and avoid burrs or connection gaps between the water diversion part 212 and the waterproof part 211, which would affect the guidance of the liquid by the water diversion part 212.

[0076] like Figure 4As shown, in one embodiment, the lower portion of the waterproof portion 211 has a lower flange 213 , and the lower flange 213 is used to block liquid from flowing from the lower portion of the waterproof portion 211 to the gas ignition hole 221 .

[0077] In this embodiment, a lower flange 213 may be provided at the edge of the lower portion of the waterproof portion 211, and the lower flange 213 may be used to block liquid from flowing from the lower portion of the waterproof portion 211 to the gas ignition hole 221. Specifically, the lower flange 213 surrounds the outer edge of the lower portion of the waterproof portion 211.

[0078] For example, a groove may be provided in the middle of the lower surface of the waterproof portion 211, and the groove cooperates with the edge of the waterproof portion 211 to form the lower flange 213. When liquid flows through the lower flange 213, the liquid is easy to drip from the lower flange 213, thereby effectively avoiding flowing to the gas ignition hole 221. In addition, the specific construction mode of the lower flange 213 may also be a convex edge formed downward around the outer edge of the waterproof portion 211, etc.

[0079] In one embodiment, the top cover 21 is provided with an upper flange 214 , and the upper flange 214 is used to prevent the liquid on the top cover 21 from flowing toward the peripheral wall 22 .

[0080] In this embodiment, an upper flange 214 may be further provided at the edge of the upper portion of the top cover 21, and the upper flange 214 is used to prevent the liquid on the top cover 21 from flowing toward the peripheral wall 22. Specifically, the upper flange 214 is provided around the outer edge of the top cover 21. The outer edge may be a circumferentially closed structure, and of course, the outer edge may also be provided with a notch away from the water diversion portion 212, so as to guide the liquid in the top cover 21 outward.

[0081] For example, a groove may be provided in the middle of the upper surface of the top cover 21, and the groove cooperates with the edge of the top cover 21 to form the upper flange 214. In addition, the specific construction mode of the upper flange 214 may also be a convex edge formed upward around the outer edge of the top cover 21, etc.

[0082] In this embodiment, in order to ensure that the water diversion portion 212 can reliably guide the liquid droplets at the waterproof portion 211 toward it, at least part of the upper surface of the waterproof portion 211 and the water diversion portion 212 is flush with the upper surface of the upper flange 214. In this way, when the liquid passes over the upper flange 214, compared with the solution in which the upper surface of the waterproof portion 211 is lower than the upper surface of the upper flange 214, the water diversion portion 212 in this embodiment can divert the liquid earlier, thereby more reliably ensuring the diversion effect of the water diversion portion 212.

[0083] For example, see Figure 3and Figure 5 The upper surfaces of the waterproof part 211 and the water guide part 212 near the edge are flush with the upper surface of the upper flange 214. The other parts of the waterproof part 211 can be inclined downward from the upper flange 214 to the center.

[0084] The water guide portion 212 may be a curved protrusion protruding from the upper flange 214, and the maximum distance of the curved protrusion from the outer arc of the upper flange 214 may be about 5 mm. Considering that the overall size of the water guide portion 212 is relatively small, the height of its upper surface may be flush with the upper surface of the upper flange 214, thereby simplifying the structure of the inner fire cover 2 while ensuring reliable drainage of the liquid droplets.

[0085] In addition, in the embodiments of the present application, other structures that can ensure that the liquid droplets at the waterproof part 211 can flow smoothly through the upper flange 214 to the water diversion part 212 are not excluded. For example, there is a smaller angle inclination from the waterproof part 211, the upper flange 214 to the water diversion part 212 as a whole.

[0086] It should be noted that, in the description of this application, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0087] The above-mentioned various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0088] The above are only a few embodiments of the present invention. Although the embodiments disclosed by the present invention are as above, the contents are only embodiments adopted for facilitating the understanding of the present invention and are not used to limit the present invention. Any technician in the technical field to which the present invention belongs can make any modification and change in the form and details of the implementation without departing from the spirit and scope disclosed by the present invention, but the scope of patent protection of the present invention shall still be subject to the scope defined by the attached claims.
