Technical Field

[0001] This application relates to the field of kitchen appliances technology, and in particular to an inner ring burner cap and a gas stove. Background Technology

[0002] A gas stove includes an inner ring burner cap, an outer ring burner cap, and a gas distribution seat. The inner and outer ring burner caps are respectively provided with flame holes. The mixture of air and gas is burned at the flame holes to heat the cookware.

[0003] Currently, gas stoves have an ignition needle located between the outer circumference of the inner ring burner cap and the annular channel of the outer ring burner cap. An ignition cap is provided on the side wall of the inner ring burner cap. When energized, an electric arc is formed between the tip of the ignition needle and the ignition cap, thus igniting the gas stove.

[0004] However, gas stoves are difficult to adapt to different sizes of ignition needles, resulting in high costs for standardizing gas stoves. Utility Model Content

[0005] Based on this, this application provides an inner ring burner cap and a gas stove to solve the problems in related technologies where gas stoves are difficult to adapt to different specifications of ignition needles and the cost of universalization of gas stoves is high.

[0006] In a first aspect, embodiments of this application provide an inner ring flame cap, wherein an ignition hole is provided on the side wall of the inner ring flame cap, and an ignition cap brim is protruding on the outer side wall of the inner ring flame cap.

[0007] The ignition cap includes a main body located above the ignition hole, with the side of the main body away from the inner ring flame cap positioned facing the ignition needle; the width of the main body is gradually varied along the circumference of the inner ring flame cap.

[0008] In one possible implementation, the side of the main body away from the inner ring fire cap sidewall is an arc-shaped wall;

[0009] Along the circumference of the inner ring flame cap, the width of the main body gradually decreases from the middle of the main body to the edge of the main body.

[0010] In one possible implementation, a flame-keeping hole is also provided on the side wall of the inner ring flame cap, and the ignition hole and the flame-keeping hole are arranged along the circumference of the inner ring flame cap.

[0011] The ignition cap also includes a tail fin located above the fire-preserving hole, the end of which is connected to the main body.

[0012] In one possible implementation, the tail section has a transition section at the end away from the main body, and the width of the transition section gradually decreases in the direction away from the main body.

[0013] There are multiple flame-protection holes, which are arranged circumferentially within the inner ring flame cover. The flame-protection holes furthest from the ignition hole are located below the transition section.

[0014] In one possible implementation, the end of the arcuate wall away from the tail fin is connected to the side wall of the inner ring fire cap.

[0015] In one possible implementation, the maximum width of the main body is 4mm-5mm, and the width of the tail fin is 1mm-2mm.

[0016] In one possible implementation, the top of the inner ring flame cap is provided with an inner ring main flame hole;

[0017] An ignition groove is provided on the outer wall of the inner ring flame cap. The ignition groove is connected to the inner ring cavity of the inner ring flame cap and is located above the ignition cap brim.

[0018] In one possible implementation, the top wall of the ignition cap is connected to the bottom wall of the ignition channel.

[0019] In one possible implementation, the top wall of the ignition cap slopes downwards gradually along the side wall away from the inner ring flame cap.

[0020] Secondly, embodiments of this application provide a gas stove, including a burner head, an ignition needle, a gas distribution seat, an outer ring burner cap, and the aforementioned inner ring burner cap;

[0021] The inner and outer ring burner caps are respectively installed on the gas distributor seat, and the outer ring burner cap has an annular channel surrounding the outer side of the inner ring burner cap.

[0022] The gas distribution cover is placed on the burner head, and the ignition needle is installed on the burner head. The ignition needle is located between the inner ring burner cover and the annular channel, and the position of the ignition needle is directly opposite the main body of the ignition cap.

[0023] The inner ring burner cap and gas stove provided in this application have ignition holes on their side walls and an ignition cap protruding from their outer side walls. The ignition cap includes a main body located above the ignition holes, and the width of the main body gradually changes along the circumference of the inner ring burner cap. This allows for different distances between the main body of the ignition cap and the ignition needle of the gas stove along the circumference of the inner ring burner cap, enabling the main body and ignition needle to accommodate different electrode discharge spacings. This improves the gas stove's compatibility with different ignition needle specifications and helps reduce the standardization cost of the gas stove. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0046] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0047] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0048] In existing technology, gas stoves have an ignition needle located between the outer periphery of the inner ring burner cap and the annular channel of the outer ring burner cap. An ignition cap is provided on the side wall of the inner ring burner cap. When energized, an electric arc is formed between the tip of the ignition needle and the ignition cap, igniting the gas stove through this arc. However, although the distance between the ignition cap and the ignition needle is consistent, different specifications of ignition needles have different electrode discharge distances, making it difficult for gas stoves to adapt to different specifications of ignition needles, resulting in high costs for standardization.

[0049] After repeated consideration and verification, the inventors discovered that if the part of the ignition cap above the ignition hole has a different width, and thus along the circumference of the inner ring burner cap, the part of the ignition cap above the ignition hole and the ignition needle have different spacing sizes, different electrode discharge distances can be accommodated between the ignition cap and the ignition needle, thus improving the gas stove's compatibility with ignition needles of different specifications.

[0050] In view of this, the inventors designed an inner ring burner cap and a gas stove. Ignition holes are formed on the side wall of the inner ring burner cap, and an ignition cap eave protrudes from the outer side wall of the inner ring burner cap. The ignition cap eave includes a main body located above the ignition holes. The main body has a gradually changing width along the circumference of the inner ring burner cap. The main body has different distances from the ignition needle of the gas stove, thus accommodating different electrode discharge spacings, allowing the gas stove to adapt to different ignition needle specifications.

[0051] The technical solutions of the inner ring burner and gas stove provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0052] Reference Figures 1 to 8 As shown in the embodiment of this application, the inner ring flame cap 300 has ignition holes 310 on its sidewall and an ignition cap 320 protruding from its outer sidewall. Part of the combustion gas in the inner ring flame cap 300 can flow out through the ignition holes 310 to form a flame at the location of the ignition hole 310. Exemplarily, there are multiple ignition holes 310, which are arranged at intervals along the circumference of the inner ring flame cap 300. The ignition cap 320 can be a sheet-like structure, with its extension direction parallel to the radial direction of the inner ring flame cap 300. Indicatively, the ignition cap 320 can be integrally formed onto the outer sidewall of the inner ring flame cap 300.

[0053] The ignition cap 320 includes a main body 321 located above the ignition hole 310. The side of the main body 321 away from the side wall of the inner ring burner cap 300 is positioned facing the ignition needle 500. The width of the main body 321 gradually changes along the circumference of the inner ring burner cap 300. Specifically, when there are multiple ignition holes 310, all of them are located below the main body 321, and there is a gap between the ignition holes 310 and the main body 321 in the axial direction of the inner ring burner cap 300. It should be noted that the width of the ignition cap 320 is its radial dimension within the inner ring burner cap 300. The ignition needle 500 of the gas stove is located on the side of the ignition cap 320 away from the side wall of the inner ring burner cap 300. Understandably, because the width of the main body 321 is gradually varied, there are different distances between the ignition needle 500 and the ignition cap 320 along the circumference of the inner ring burner cap 300. When the ignition needle 500 is energized, an electric arc is formed between its tip and a suitable position on the side of the ignition cap 320 away from the side wall of the inner ring burner cap 300. This electric arc can ignite the gas ejected from the ignition hole 310.

[0054] The inner ring burner cap 300 provided in this embodiment has a different distance between the main body 321 of the ignition cap 320 and the ignition needle 500 of the gas stove along the circumference of the inner ring burner cap 300. The main body 321 and the ignition needle 500 can be compatible with different electrode discharge spacing, which improves the compatibility of the gas stove with different specifications of ignition needles 500 and helps to reduce the generalization cost of the gas stove.

[0055] Furthermore, since the ignition hole 310 is located below the main body 321 of the ignition cap 320, the main body 321 of the ignition cap 320 can block and guide the downward-flowing oil-water mixture, preventing it from clogging the ignition hole 310. This improves the ignition success rate and stability of the gas stove, reducing the probability of maintenance. Additionally, the ignition cap 320 can block some of the downward-flowing airflow, allowing the gas stove to reliably ignite and maintain a flame even in harsh environments such as low temperatures and windy conditions.

[0056] In one embodiment, such as Figures 3 to 5 and Figure 9 As shown, the side of the main body 321 away from the sidewall of the inner ring flame cap 300 is an arc-shaped wall. For example, the arc-shaped wall extends along the axial direction of the inner ring flame cap 300.

[0057] Along the circumference of the inner ring burner cap 300, the width of the main body 321 gradually decreases from the middle of the main body 321 to its edge. The distance between the arc-shaped wall and the ignition needle 500 along the circumference of the inner ring burner cap 300 is different, and different specifications of ignition needles 500 can form an electric arc with different positions of the arc-shaped wall.

[0058] Because the distance between the arc-shaped wall and the ignition needle 500 is different along the circumference of the inner ring burner cap 300, different electrode discharge spacings can be accommodated between the arc-shaped wall and the ignition needle 500, thus improving the compatibility of the gas stove with different specifications of ignition needles 500.

[0059] In a specific embodiment, such as Figures 3 to 7 and Figure 9 As shown, a flame-holding hole 330 is also provided on the side wall of the inner ring burner cap 300, and the ignition hole 310 and the flame-holding hole 330 are arranged circumferentially along the inner ring burner cap 300. For example, there are multiple flame-holding holes 330, located on one side of the ignition hole 310, and the multiple flame-holding holes 330 and the ignition hole 310 are arranged at intervals along the circumferential direction of the inner ring burner cap 300. It can be understood that some of the gas in the inner ring burner cap 300 can be ejected from the flame-holding hole 330, and the flame at the ignition hole 310 can sequentially ignite the gas ejected from the flame-holding hole 330 to form a flame at the flame-holding hole 330.

[0060] Those skilled in the art will understand that the flame-keeping hole 330 corresponds to the thermocouple 600 of the gas stove. When the gas stove is burning, the thermocouple 600 can detect whether the gas stove has accidentally extinguished by detecting whether there is a flame at the corresponding flame-keeping hole 330 position. The thermocouple 600 can be connected to a flameout protection device. When the gas stove accidentally extinguishes, the flameout protection device can cut off the gas supply to the gas stove to prevent gas leakage and ensure the safety and reliability of the gas stove.

[0061] The ignition cap 320 also includes a tail fin 322 located above the flame arrestor 330, the end of which is connected to the main body 321. Specifically, the tail fin 322 is connected to the main body 321 at one end of the inner ring flame cap 300 in the circumferential direction, and the width of the main body 321 of the ignition cap 320 gradually decreases as it transitions towards the tail fin 322. When there are multiple flame arrestors 330, all of them are located below the tail fin 322. A gap exists between the tail fin 322 and the flame arrestor 330 below it in the axial direction of the inner ring flame cap 300.

[0062] This structure allows the tail fin 322 to block part of the downward airflow. At the same time, the tail fin 322 can also block and guide the downward flow of oil-water mixture, preventing the oil-water mixture from clogging the flame-keeping hole 330. This ensures stable combustion of the flame at the flame-keeping hole 330, thereby guaranteeing the accuracy of the thermocouple 600 detection and reducing the probability of gas stove maintenance.

[0063] In a more specific embodiment, such as Figures 3 to 5 and Figure 9As shown, the tail fin 322 has a transition section 3221 at the end away from the main body 321, and the width of the transition section 3221 gradually decreases in the direction away from the main body 321. Exemplarily, the transition section 3221 is arranged obliquely on the side away from the sidewall of the inner ring flame cap 300. Schematably, along the circumference of the inner ring flame cap 300, the main body 321 of the tail fin 322, excluding the transition section 3221, has a uniform width. The ignition cap 320 has a streamlined, gradually changing width design.

[0064] There are multiple flame-keeping holes 330, which are arranged circumferentially within the inner ring flame cap 300. The flame-keeping holes 330 that are far from the ignition hole 310 are located below the transition section 3221.

[0065] For example, multiple flame-retardant holes 330 are located to the right of the ignition hole 310, with the rightmost flame-retardant hole 330 located below the transition section 3221. The flame at the ignition hole 310 can propagate from left to right to sequentially ignite the gases ejected from the multiple flame-retardant holes 330. Figure 3 , Figure 4 , Figure 7 and Figure 9 As shown, the top of the inner ring burner cap 300 is provided with an inner ring main burner hole 340, which is connected to the interior of the inner ring burner cap 300. The flame located at the rightmost flame-keeping hole 330 can propagate upwards and ignite the gas ejected from the inner ring main burner hole 340 to form a flame at the inner ring main burner hole 340.

[0066] With the above configuration, a transition section 3221 is provided at the end of the tail fin 322, which facilitates the upward propagation of the flame at the position of the flame retention hole 330, which is far away from the ignition hole 310. This helps to improve the gas stove's pass-through efficiency and enhance the user's experience.

[0067] like Figure 3 As shown, the end of the arc-shaped wall away from the tail fin 322 is connected to the side wall of the inner ring flame cap 300. For example, the left end of the arc-shaped wall is connected to the side wall of the inner ring flame cap 300, and the right end of the arc-shaped wall is connected to the tail fin 322.

[0068] This structure, because the end of the arc-shaped wall away from the tail fin 322 is connected to the side wall of the inner ring burner cap 300, allows for a larger distance range between the arc-shaped wall and the ignition needle 500. This allows for more different electrode discharge spacings between the main body 321 and the ignition needle 500, further improving the gas stove's compatibility with different specifications of ignition needles 500 and further reducing the cost of standardization of the gas stove.

[0069] In one possible implementation, the maximum width of the main body 321 is 4mm-5mm, and the width of the tail fin 322 is 1mm-2mm.

[0070] For example, the maximum width of the main body 321 can be 4mm, 4.2mm, 4.5mm, 4.8mm, or 5mm, etc., and is not limited to a single value. When the maximum width of the main body 321 is less than 4mm, the distance between the main body 321 and the ignition needle 500 is relatively small, and the gas stove can only accommodate a limited range of ignition needle 500 specifications. When the maximum width of the main body 321 is greater than 5mm, interference between the main body 321 and the ignition needle 500 is likely to occur. Therefore, by limiting the maximum width of the main body 321, interference between the main body 321 and the ignition needle 500 is avoided while ensuring that the gas stove can accommodate a wider range of ignition needle 500 specifications. The gas stove can accommodate electrode discharge gaps of 2.5mm-5.5mm.

[0071] For example, the width of the tail fin 322 can be 1mm, 1.2mm, 1.5mm, 1.8mm, or 2mm, etc., and is not limited to a single value. It should be noted that the flame at the flame-holding hole 330 below the tail fin 322 can propagate upwards to ignite the gas ejected from the inner ring main flame hole 340. When the width of the tail fin 322 is greater than 2mm, it hinders the upward propagation of the flame at the flame-holding hole 330; when the width of the tail fin 322 is less than 1mm, the tail fin 322 has a smaller obstruction effect on the downward-flowing airflow and the oil-water mixture, and a smaller effect on improving the flame stability at the flame-holding hole 330. In other words, by limiting the width of the tail fin 322, it is ensured that the flame at the flame-holding hole 330 can propagate upwards smoothly, while also ensuring the stability of the flame at the flame-holding hole 330, thereby ensuring the accuracy of the thermocouple 600 detection.

[0072] In one embodiment, such as Figure 3 , Figure 6 , Figure 10 and Figure 11 As shown, the top of the inner ring burner cap 300 is provided with an inner ring main flame hole 340. In one possible implementation, multiple inner ring protrusions 360 are arranged in a ring array around the axis of the inner ring burner cap 300, defining a "three-dimensional petal structure". Each inner ring protrusion 360 is provided with an inner ring main flame hole 340, so that the multiple inner ring main flame holes 340 are evenly distributed on the inner ring burner cap 300. The distance between each inner ring main flame hole 340 and the axis of the inner ring burner cap 300 gradually increases from bottom to top. Through the evenly distributed inner ring main flame holes 340 on the inner ring burner cap 300 and the evenly distributed outer ring main flame holes 230 on the outer ring burner cap 200, the effective contact area and uniformity between the gas stove flame and the bottom of the pot are effectively improved, so that the temperature gradient at all parts of the pot transitions smoothly, achieving uniform temperature throughout the pot, which is particularly beneficial for cooking scenarios such as frying where high temperature uniformity is required.

[0073] An ignition groove 350 is formed on the outer wall of the inner ring flame cap 300. The ignition groove 350 communicates with the inner ring cavity of the inner ring flame cap 300 and is located above the ignition cap 320. The ignition groove 350 extends laterally. Part of the combustion gas in the inner ring flame cap 300 can be ejected through the ignition groove 350. The flame at the flame-holding hole 330 can propagate upwards to the ignition groove 350, forming a ring-shaped flame surrounding the inner ring flame cap 300 at the ignition groove 350 location. Figure 3 , Figure 5 and Figure 10 As shown, multiple ignition holes 370 are evenly arranged in the circumferential direction on the inner side of the ignition groove 350. The ignition holes 370 can extend in a direction parallel to the axis of the inner ring flame cap 300, and the ignition groove 350 and the interior of the inner ring flame cap 300 are connected through the ignition holes 370.

[0074] By setting an ignition groove 350 between the flame-holding hole 330 and the inner ring main flame hole 340, a multi-stage ignition path is formed by the ignition hole 310, the flame-holding hole 330, the ignition groove 350, and the inner ring main flame hole 340. This facilitates the upward propagation of the flame at the flame-holding hole 330 to ignite the gas emitted from the inner ring main flame hole 340. When the interval between two adjacent inner ring main flame holes 340 is large, the annular flame formed at the ignition groove 350 can ignite the gas emitted from different inner ring main flame hole positions. The flame transmission process of the gas stove is as follows: Figure 11 As shown by the middle arrow, once a flame forms at the inner ring main burner hole 340, the flame at that location can propagate outwards to ignite the gas emitted from the outer ring main burner hole 230. This allows the gas stove to achieve a rapid and stable flame propagation effect.

[0075] Furthermore, the ignition hole 310, flame-holding hole 330, ignition groove 350, and inner ring main flame hole 340 on the inner ring burner cap 300 can effectively and evenly disperse the static pressure of the combustion gas inside the inner ring burner cap 300. When the static pressure of the combustion gas inside the inner ring burner cap 300 is high, the ignition groove 350 can play a role in depressurization, making the gas release at the flame hole outlet of the inner ring burner cap 300 uniform and stable. This can effectively solve the problems of flame detachment and slow flame propagation under special combustion conditions such as high pressure, cold state, and flame-removal boundary gas, and enable the flame-holding hole 330 and other parts to achieve stable flame combustion and diffusion under the above-mentioned harsh conditions.

[0076] In one possible implementation, such as Figure 3 and Figure 10 As shown, the top wall of the ignition cap 320 is connected to the bottom wall of the ignition groove 350.

[0077] Specifically, the top wall of the ignition cap 320 facing the side wall of the inner ring flame cap 300 is connected to the bottom wall of the ignition groove 350 away from the axis of the inner ring flame cap 300. When the ignition cap 320 and the ignition groove 350 are integrally formed on the inner ring flame cap 300, the above arrangement facilitates the mold manufacturing and demolding of the inner ring flame cap 300, which helps to reduce the processing cost of the inner ring flame cap 300.

[0078] Optionally, the top wall of the ignition cap 320 gradually slopes downward along the side wall away from the inner ring flame cap 300.

[0079] Specifically, the top wall of the ignition cap 320 gradually slopes downwards along the radial direction of the inner ring burner cap 300, away from the axis of the inner ring burner cap 300. When the oil-water mixture flowing downwards reaches the top wall of the ignition cap 320, the top wall of the ignition cap 320 can guide the oil-water mixture thereon to flow away from the axis of the inner ring burner cap 300. For example, the top wall of the ignition cap 320 can be a plane inclined to the horizontal plane. Those skilled in the art can set the angle between the top wall of the ignition cap 320 and the horizontal plane as needed, and no unique limitation is made here.

[0080] With the above settings, when the oil-water mixture flows to the top wall of the ignition cap 320, the top wall of the ignition cap 320 can guide the oil-water mixture to move away from the ignition channel 350, preventing the oil-water mixture from flowing into the ignition channel 350 and causing blockage of the ignition channel 350, thus reducing the probability of gas stove use and maintenance.

[0081] This application also provides a gas stove, including a burner head 400, an ignition needle 500, a gas distributor 100, an outer ring burner cap 200, and the aforementioned inner ring burner cap 300. The inner ring burner cap 300 and the outer ring burner cap 200 are respectively mounted on the gas distributor 100, and the outer ring burner cap 200 has an annular channel 210 surrounding the outer side of the inner ring burner cap 300.

[0082] The gas distributor 100 serves to distribute the combustion gas, allowing it to flow into both the outer ring burner cap 200 and the inner ring burner cap 300. A portion of the combustion gas enters the annular channel 210 of the outer ring burner cap 200 via the gas distributor 100. In one possible implementation, the top of the annular channel 210 is arranged in a circular array around the axis of the outer ring burner cap 200, with multiple outer ring protrusions 220 defining an approximate "three-dimensional petal structure." Each outer ring protrusion 220 is provided with an outer ring main flame hole 230, ensuring that the multiple outer ring main flame holes 230 are evenly distributed on the outer ring burner cap 200. Each outer ring main flame hole 230 communicates with the interior of the annular channel 210, allowing the combustion gas in the annular channel 210 to be ejected from the multiple outer ring main flame holes 230, thus forming a uniform flame on the outer ring burner cap 200.

[0083] For example, a mounting base is provided in the middle of the outer ring flame cover 200, and the inner ring flame cover 300 is placed on the mounting base and fixed to the mounting base. The inner ring flame cover 300 and the outer ring flame cover 200 can be fastened together by fasteners. The mounting base is provided with screw holes 240 for fasteners to pass through, and the inner ring flame cover 300 is provided with fastening holes 380 for fasteners to lock in place.

[0084] In one possible implementation, the inner ring burner cap 300, the outer ring burner cap 200, and the gas distributor 100 can be connected into a whole. By locking the inner ring burner cap 300, the outer ring burner cap 200, and the gas distributor 100 into an integrated structure in upper and lower layers, the probability of the burner cap not being placed in place can be reduced, thereby reducing the probability of gas leaks, flame leaks, and deflagration of the gas stove, and improving the safety and reliability of the gas stove. At the same time, it has advantages in uniform flame distribution and even combustion, and heating of the pots and pans at the same temperature.

[0085] The gas distribution seat 100 is placed on the burner head 400, and the ignition needle 500 is installed on the burner head 400. The ignition needle 500 is located between the inner ring burner cover 300 and the annular channel 210, and the position of the ignition needle 500 is directly opposite the main body 321 of the ignition cap 320.

[0086] The burner head 400 directs gas into the gas distribution seat 100 of the gas stove. The gas stove also includes a thermocouple 600 installed on the burner head 400. The ignition needle 500 and the thermocouple 600 are located between the annular channel 210 of the outer ring burner cap 200 and the inner ring burner cap 300, respectively. The ignition needle 500 is positioned towards the ignition hole 310 of the inner ring burner cap 300, and the thermocouple 600 is positioned towards the flame retention hole 330 of the inner ring burner cap 300.

[0087] The gas stove provided in this application, due to the use of the aforementioned gas stove, is applicable to different specifications of ignition needles 500, resulting in lower universality costs for the gas stove, and the ignition hole 310 of the gas stove is not easily blocked, thus reducing the probability of use and maintenance of the gas stove.
