Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a stove panel and a stove. Background Art

[0002] With the development of the times, various stoves have been widely used in the kitchens of thousands of households. The panel of the stove determines many key factors such as the stove's aesthetics, ease of cleaning, and safety.

[0003] Taking a common gas stove as an example, the stove panel on the market usually adopts a tempered glass panel. The surface of the tempered glass panel is flat and easy to clean, and has good impact resistance.

[0004] The tempered glass panel is at risk of bursting when heated unevenly or the edges and corners are damaged, seriously affecting the safety of the stove. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, some embodiments of the utility model provide a stove panel, including: a steel plate; a first galvanized layer and a second galvanized layer, the first galvanized layer and the second galvanized layer respectively covering the upper surface and the lower surface of the steel plate; and a plastic powder spray layer, the plastic powder spray layer including a first plastic powder spray layer, the first plastic powder spray layer covering the upper surface of the first galvanized layer. Using the steel plate as the substrate can meet the requirements of hardness and strength, and the cost is relatively reasonable. The galvanized layer can prevent the steel plate from rusting and corroding, and the first plastic powder layer can not only protect the galvanized layer, but also prevent the galvanized layer from contaminating food.

[0006] Exemplarily, the plastic powder spraying layer further includes: a second plastic powder spraying layer, the second plastic powder spraying layer covers the lower surface of the second galvanized layer. The second plastic powder layer can protect the galvanized layer on the other side of the steel plate and can also improve the yield rate.

[0007] Exemplarily, the plastic powder spraying layer further comprises: a third plastic powder spraying layer, and the third plastic powder spraying layer covers the side surface of the steel plate. Covering the third plastic powder layer can protect the non-galvanized side surface.

[0008] For example, the steel plate is flat, so that dirt is not easy to accumulate on the surface of the steel plate, it is easy to clean, and the user experience is good.

[0009] For example, the cooker panel is provided with a first opening for the burner to pass through, and the edge of the first opening is provided with a rubber coating layer. The rubber coating layer can not only seal the burner and the cooker panel to prevent pollutants from leaking from the first opening, but also protect the surface of the steel plate where the first opening is located to prevent rust.

[0010] Exemplarily, the cooker panel is provided with a second opening for the valve stem of the adjusting knob to pass through, and the edge of the second opening is provided with a rubber coating. The rubber coating of the second opening can also play a role of rust prevention and sealing.

[0011] For example, the weight of the first galvanized layer and the second galvanized layer per square meter of the steel plate is not less than 30 grams. Controlling the weight of the galvanized layer per square meter of the steel plate can ensure the thickness of the galvanized layer on the surface of the steel plate, and prevent holes from appearing due to the thin thickness of the galvanized layer when oxidized.

[0012] For example, a passivation layer is formed on the upper surface of the first galvanized layer. Forming the passivation layer on the surface of the first galvanized layer can reduce the chemical activity of the surface, slow down the corrosion rate of the first galvanized layer, and thus extend the service life of the cooker panel.

[0013] For example, a passivation layer is formed on the lower surface of the second galvanized layer. The passivation layer on the lower surface of the second galvanized layer can slow down the corrosion rate of the second galvanized layer.

[0014] Exemplarily, the thickness of the plastic powder spray coating is between 30 microns and 120 microns. Since the hardness of plastic is relatively low, if the thickness of the plastic powder spray coating is too high, it is easier to form scratches and pits on the surface under the action of external forces such as gravity impact. If the thickness of the plastic powder spray coating is too thin, stains and oxygen may penetrate through the plastic powder spray coating, and the anti-corrosion performance may be reduced.

[0015] Exemplarily, the cooker panel further includes an edge strip, which surrounds and covers the side surface of the steel plate. The edge strip can protect the edges and corners of the cooker panel that are easily damaged.

[0016] Exemplarily, the cooker panel further includes a sealing strip, which extends along the edging strip, is arranged at the bottom of the edging strip, and the bottom surface of the sealing strip is flush with or protrudes from the bottom surface of the edging strip. The sealing strip is arranged at the bottom of the edging strip, so that the edging strip can not only provide a certain protection to the panel, but also provide a certain protection to the sealing strip, which can extend the service life of the sealing strip and make the appearance more concise. Corresponding to different types of sealing strips, the bottom surface of the sealing strip can also be flush with or protrude from the bottom surface of the edging strip, thereby providing the best sealing effect.

[0017] Exemplarily, the edging strip includes: a covering portion, which covers the side surface of the cooker panel; and a supporting portion, which is arranged on the inner side surface of the covering portion and is spaced from the bottom surface of the covering portion, and the edge of the steel plate is supported on the upper surface of the supporting portion; and a sealing strip is arranged below the supporting portion and located on the inner side of the covering portion. In short, the supporting portion enables the edging strip to support the cooker panel. Compared with fixing the cooker panel to the edging strip by welding, riveting, bonding, etc., by providing the supporting portion, the downward force of the cooker panel can be carried most simply and reliably, so that the cooker panel and the edging strip are relatively fixed, and will not sink when subjected to downward pressure, and the user experience is good.

[0018] Exemplarily, the edging strip also includes a protrusion, which extends downward from the support portion and is spaced apart from the covering portion. The support portion, the protrusion and the covering portion together form a mounting groove, and the sealing strip is embedded in the mounting groove. The edging strip can completely surround the sealing strip with the countertop to minimize the damage of the sealing strip under the action of external force. When the length of the protrusion and the covering portion are equal, they can be supported on the countertop together, and the ability to withstand pressure is stronger. The protrusion can be longer than the covering portion. When the cooker is installed on the countertop, the protrusion can extend into the installation opening to limit the position of the cooker.

[0019] Exemplarily, the upper surface of the support portion is provided with a glue groove, in which an adhesive is provided, and the cooker panel is fixed to the support portion by the adhesive. The glue groove can increase the contact area between the adhesive and the edge strip, thereby improving the bonding performance.

[0020] Exemplarily, the edge of the cooker panel includes a plurality of straight edges and a plurality of corners connected between the plurality of straight edges. Along the direction surrounding the cooker panel, the covering portion includes a plurality of first sections and a plurality of second sections, wherein: the plurality of first sections respectively cover the side surfaces of the plurality of straight edges, the plurality of second sections respectively cover the side surfaces of the plurality of corners, the plurality of second sections are connected between the plurality of first sections, and the support portion is arranged on the first section. The second section may include the covering portion without the support portion, and the covering portion has a smaller thickness in the bending direction, which can facilitate bending. The support portion may be arranged on the first section to support the cooker panel.

[0021] For example, the covering portion is in the form of a sheet that fits the side surface of the cooker panel, the supporting portion extends horizontally, and the supporting portion is connected to the middle portion of the first section in the vertical direction, so that the cross section of the first section is T-shaped. Since the inner side of the sealing strip is hardly contaminated, it is not necessary to make the edging strip cover the sealing strip from both sides in the horizontal direction, and the T-shaped edging strip has a simple structure and low cost.

[0022] For example, the ends of the support parts on the adjacent first sections are spaced apart from each other and form a notch, and the notch is located on the inner side of the second section. When the edge strip is processed by bending, it is usually necessary to avoid the support part. Therefore, the ends of the support parts on the adjacent first sections are spaced apart from each other and form a notch, and the notch is located on the inner side of the second section. This structure is relatively simple and the processing cost is lower.

[0023] For example, the end of each support portion is spaced apart from the inner side surface of the first section where it is located, and the spacing groove is arranged concentrically with the rounded corner of the bend. In this way, during the bending process, almost only the first section bends, and the support portion will not be deformed by the force during the bending. During the bending process, the material will not be squeezed and deformed to produce an uneven surface in the vertical direction, which will affect the assembly of the cooker panel.

[0024] Exemplarily, along the extension direction of the edging strip, the end of each support portion protrudes from the first section where it is located. In this way, the edging strip can be bonded to the corner of the cooker panel and can also provide support for the corner of the cooker panel.

[0025] Exemplarily, the width of the notch is between 0.5 mm and 2 mm. If the notch is too large, since the corner of the stove panel corresponds to the notch, the stove panel and the edging strip cannot be bonded together by adhesive at the notch, which may cause the stove panel and the edging strip to be loosely bonded at the corner. If the notch is too small, the supporting parts on both sides of the notch may interfere with each other. In the case where the edging strip is bent using a profile, the position corresponding to the corner of the stove panel cannot be bent to a corresponding angle of, for example, 90 degrees. Therefore, a reasonable setting of the notch size can ensure that the stove panel and the edging strip are reliably bonded, and the structure is simple.

[0026] For example, a glue groove is provided on the upper surface of the support portion, the glue groove extends to the end of the support portion, an adhesive is provided in the glue groove, and the cooker panel is fixed to the support portion by the adhesive. The glue groove can increase the contact area between the adhesive and the edge strip, thereby improving the bonding performance.

[0027] Exemplarily, the upper surface of the edge strip is not higher than the upper surface of the first plastic powder spray coating. Ideally, the upper surface of the edge strip is completely flush with the upper surface of the first plastic powder spray coating. Due to the limitation of processing accuracy, preferably, the edge strip is slightly lower than the upper surface of the first plastic powder spray coating, so that when cleaning the stove panel, stains will not be blocked by the edge strip and accumulated, and the processing accuracy requirements can be reduced, thereby reducing costs. During use, the edge strip is not easily separated from the side surface of the stove panel by an external force that is not directed away from the side surface of the stove panel.

[0028] For example, there is one edge strip, and there is a seam between the end surfaces of the two ends of the edge strip, and the seam is located at the straight edge of the steel plate. By using one edge strip to surround the steel plate, only one seam can be generated. In the actual production process, a straight profile is bent to form a structure that surrounds the steel plate, which has lower processing costs, simple structure and higher yield rate.

[0029] According to another aspect of the present application, a stove is provided, comprising: the stove panel assembly described above; and a burner head, wherein an opening is provided on the stove panel assembly, and the burner head is passed through the opening.

[0043] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0044] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0045] The embodiment of the utility model provides a stove. The stove according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings. The stove can be installed on a countertop, which includes but is not limited to a cabinet, a dish rack cabinet, and an upper surface of an integrated stove for installing the stove. Figure 1A and Figure 2As shown, the stove may include a stove panel 100 and a burner. A first opening 130 may be provided on the stove panel 100, and the burner is inserted through the first opening 130. A mounting opening may be provided on the countertop for mounting the stove, and when the stove is mounted on the countertop, the burner portion may pass through the mounting opening and enter the space below the countertop. The stove panel 100 may have a size larger than the mounting opening, and the larger stove panel 100 may be stuck on the upper surface of the countertop and completely cover the mounting opening. A gas pipeline may be provided in the space below the countertop, and the gas pipeline may be connected to the burner. In this way, the gas pipeline will not be exposed to the outside, which is more beautiful and safe. Figure 1A Taking the stove shown as an example, the opening corresponding to the burner can be set to any size between 100mm-230mm to adapt to burners of different models. The width of the stove panel 100 can be between 400mm-460mm, and the length can be constructed between 700mm-850mm to correspond to the common countertop width.

[0046] like Figure 1B As shown, the cooker panel 100 may include a steel plate 101, and the steel plate 101 may include any suitable steel such as alloy steel, high-speed steel, carbon steel, etc. For ease of description, the cooker panel 100 is taken as an example of common carbon steel. Carbon steel has good thermal conductivity, and the problem of uneven heating and edge warping will not occur at a large thickness. In addition, carbon steel has high hardness and strength, and can withstand external forces such as pressing and collision during daily use. In the environment of high temperature and high humidity in the kitchen and the presence of stains, in order to prevent carbon steel from rusting, the cooker panel 100 may include a first galvanized layer 102 and a second galvanized layer 103. The first galvanized layer 102 and the second galvanized layer 103 are respectively covered on the upper surface and the lower surface of the steel plate 101. In this way, the surface of the steel plate 101 can be isolated from the air, and when corroded, the pollutants can react with the more active galvanized layer first to protect the steel plate 101. Furthermore, the cooker panel 100 includes a plastic powder spray coating, and the plastic powder spray coating includes a first plastic powder spray coating 105, and the first plastic powder spray coating 105 is covered on the upper surface of the first galvanized layer 102. Due to the cooking process, the surface of the cooker panel 100 may be contaminated. Taking vinegar as an example, the pollutant can react with the galvanized layer, causing the galvanized layer to be corroded, and at least difficult-to-remove marks will be formed on the surface of the galvanized layer, affecting the appearance. In addition, during the cooking process, the galvanized layer may evaporate under high temperature baking, and may also contact food, affecting the health of users. The first plastic powder spray coating 105 is covered on the surface of the first galvanized layer 102. The plastic material is usually chemically stable, does not react with common pollutants, and is relatively easy to clean. The first plastic powder layer can also prevent the galvanized layer from evaporating or directly contacting food during use.

[0047] In short, using the steel plate 101 as the substrate can meet the requirements of hardness and strength, and the cost is relatively reasonable. The galvanized layer can prevent the steel plate 101 from rusting and corrosion, and the first plastic powder layer can protect the galvanized layer and prevent the galvanized layer from contaminating food.

[0048] Exemplarily, the plastic powder spray layer also includes a second plastic powder spray layer 106, which covers the lower surface of the second galvanized layer 103. The second plastic powder layer can protect the galvanized layer on the other side of the steel plate 101. Since the hardness of plastic is relatively small compared to materials such as glass, scratches and other defects may occur during the assembly process. At this time, the second plastic powder spray layer 106 can also be exposed as an upper surface, which can improve the yield rate. Exemplarily, the plastic powder spray layer can include a third plastic powder spray layer 107, which covers the side surface of the steel plate 101. When the stove panel 100 is processed, it is usually cut and formed from a larger plate or steel coil. Before cutting and forming, the galvanized layer has already covered the surface of the plate or steel coil. Therefore, there will be no galvanized layer on the side of the steel plate 101 of the stove panel 100 after cutting. Covering the third plastic powder layer can protect the ungalvanized side surface.

[0049] For example, the steel plate 101 is flat. Since the selected steel plate 101 has good thermal conductivity, the steel plate 101 can have a sufficient thickness and does not need to be provided with a reinforcing rib structure. In this way, the surface of the steel plate 101 is not easy to accumulate dirt, is easy to clean, and provides a good user experience.

[0050] Specifically, the thickness of the steel plate 101 can be any size between 1.8 mm and 4 mm. It can be understood that for the stove panel 100 with a larger length and width, if the thickness is less than 1.8 mm, the stove panel 100 is not rigid enough and is easy to deform because no reinforcing ribs are provided. If the thickness is greater than 4 mm, it is not only heavy, but also difficult to package and transport, and the cost will also increase significantly. Preferably, the thickness of the stove panel 100 can be determined to be between 2.5 mm and 3 mm.

[0051] As described above, illustratively, the stove panel 100 is provided with a first opening 130 for the burner to pass through, and the edge of the first opening 130 may be provided with a rubber coating. Similar to the side surface of the steel plate 101, the inner surface of the steel plate 101 corresponding to the first opening 130 is exposed to the outside and is not protected by a galvanized layer. Providing a rubber coating can not only seal the burner and the stove panel 100 to prevent pollutants from leaking from the first opening 130, but also protect the surface of the steel plate 101 where the first opening 130 is located to prevent rust. Exemplarily, the stove panel 100 may also be provided with a second opening 140 for the valve stem of the adjusting knob to pass through, and the edge of the second opening 140 may be provided with a rubber coating. The rubber coating of the second opening 140 may also have an anti-rust and sealing effect. Figure 1AIn the illustrated embodiment, the diameter of the second opening 140 may be between 16 mm and 35 mm.

[0052] Exemplarily, the weight of the first galvanized layer 102 and the second galvanized layer 103 covering each square meter of the steel plate 101 is not less than 30 grams. The galvanized layer can form a dense oxide layer after reacting with air, which protects the galvanized layer and the steel plate 101 below. Controlling the weight of the galvanized layer covering each square meter of the steel plate 101 can ensure the thickness of the galvanized layer on the surface of the steel plate 101, and no holes will appear due to the thin thickness of the galvanized layer when oxidized. Preferably, the weight of the first galvanized layer 102 and the second galvanized layer 103 covering each square meter of the steel plate 101 can be 40 grams.

[0053] Exemplarily, a passivation layer 104 is formed on the upper surface of the first galvanized layer 102. Forming the passivation layer 104 on the surface of the first galvanized layer 102 can reduce the chemical activity of its surface, slow down the corrosion rate of the first galvanized layer 102, and thus extend the service life of the cooker panel 100. Exemplarily, a passivation layer 104 is formed on the lower surface of the second galvanized layer 103. The passivation layer 104 on the lower surface of the second galvanized layer 103 can slow down the corrosion rate of the second galvanized layer 103.

[0054] Exemplarily, the thickness of the plastic powder spray coating is between 30 microns and 120 microns. Since the hardness of plastic is relatively low, if the thickness of the plastic powder spray coating is too high, it is easier to form scratches and pits on the surface under the action of external forces such as gravity impact. If the thickness of the plastic powder spray coating is too thin, stains and oxygen may penetrate through the plastic powder spray coating, and the anti-corrosion performance may decrease. Preferably, the plastic powder spray coating can be controlled at 50-60 microns. In order to avoid the sharp edges and corners of the stove panel 100 from cutting hands, and to prevent the plastic powder spray coating at the corners from easily falling off, the edges and corners of the steel plate 101 can be chamfered or processed into small fillets before coating the plastic powder spray coating.

[0055] The cooker panel 100 may further include an edge strip 200, which surrounds and covers the side surface of the steel plate 101. As described above, the corners of the cooker panel 100 are more likely to be damaged after being bumped. The edge strip 200 can at least completely cover the corners formed at the junction of the side surface and the lower surface of the cooker panel 100, thereby preventing the corners from being bumped and damaged. Exemplarily, the upper surface of the edge strip 200 can be flush with, slightly higher than, or slightly lower than the upper surface of the cooker panel 100, thereby protecting the corners at the junction of the upper surface and the side surface of the cooker panel 100.

[0056] Figure 32 shows a cross-sectional view of an exemplary embodiment of the edge strip 200. Exemplarily, the cooker panel 100 may further include a sealing strip 300, which extends along the edge strip 200. The sealing strip 300 may be disposed at the bottom of the edge strip 200, and the bottom surface of the sealing strip 300 may be flush with or protrude from the bottom surface of the edge strip 200.

[0057] The sealing strip 300 of the cooker panel 100 may extend along the edging strip 200. The sealing strip 300 may include a rubber sealing strip, a sponge sealing strip, etc. When the cooker panel 100 is mounted on the countertop, the sealing strip 300 may fill the gap between the cooker panel 100 and the countertop, thereby preventing foreign matter such as oil stains, dust, etc. from leaking through the gap into the installation opening reserved for the burner of the cooker. Preferably, the sealing strip 300 may surround the installation opening of the countertop to prevent foreign matter such as oil stains, dust, etc. from passing through the gap and falling into the installation opening.

[0058] In an exemplary embodiment, the sealing strip 300 may be partially exposed from the side of the cooker panel 100. In an exemplary embodiment, the sealing strip 300 may be completely blocked by the edging strip 200 from the side of the cooker panel 100. For example, the sealing strip 300 may be located on the inner side of the edging strip 200, and dirt will only contact the sealing strip 300 through the gap between the edging strip 200 and the countertop, which can largely avoid the sealing strip 300 from being worn and extend the service life of the sealing strip 300. In a preferred embodiment, when the cooker is installed on the countertop, the sealing strip 300 can be compressed so that the bottom surface of the edging strip 200 can be close to the countertop. At this time, the edging strip 200 can surround the sealing strip 300 inside, so that the sealing strip 300 is almost not subject to external wear. This can effectively extend the service life of the sealing strip 300. For example, the edging strip 200 can be made of aluminum alloy, and its surface can also be anodized to ensure strength, corrosion resistance and beauty. Figure 4A cross-sectional view of the edging strip 200 of another exemplary embodiment is shown. As shown in the figure, the sealing strip 300 can be embedded in the bottom surface of the edging strip 200. In this embodiment, the edging strip 200 can completely surround the sealing strip 300 with the countertop, and the sealing strip 300 can be prevented from being damaged by external forces to the greatest extent. In the case where the sealing strip 300 can be compressed, the bottom surface of the sealing strip 300 can protrude from the bottom surface of the edging strip 200. In this way, when the cooker is installed on the countertop, the sealing strip 300 is compressed and can automatically fill the gap between the cooker panel 100 and the countertop. This can prevent foreign matter from entering the installation opening of the countertop from the gap. When the sealing strip 300 is made of an incompressible material, the bottom surface of the sealing strip 300 can be flush with the bottom surface of the edging strip 200, so that when the cooker is installed on the countertop, the edging strip 200 can fit the countertop. In this way, there will be no large gap between the edging strip 200 and the countertop, it is not easy to hide dirt, and the surface is more concise. The bottom surface of the sealing strip 300 may also protrude from the bottom surface of the edging strip 200 , so that the edging strip 200 does not support the stove, and the gravity of the stove is supported by the sealing member 300 , so that the sealing member 300 can fit tightly against the tabletop.

[0059] Exemplarily, the edging strip 200 may include a covering portion 210 and a supporting portion 220, and the covering portion 210 may be covered on the side surface of the cooker panel 100. The supporting portion 220 is arranged on the inner side of the covering portion 210 and is spaced apart from the bottom surface of the covering portion 210, and the edge of the steel plate 101 is supported on the upper surface of the supporting portion 220. The sealing strip 300 is arranged below the supporting portion 220 and is located on the inner side of the covering portion 210. The supporting portion 220 enables the edging strip 200 to support the cooker panel 100. Compared with fixing the cooker panel 100 to the edging strip 200 by welding, riveting, bonding, etc., by providing the supporting portion 220, the downward force of the cooker panel 100 can be carried most simply and reliably, so that the cooker panel 100 is relatively fixed to the edging strip 200, and will not sink when subjected to downward pressure, and the user experience is good. Exemplarily, the covering portion 210 is in the form of a sheet that fits the side surface of the cooker panel 100, the supporting portion 220 extends horizontally, and the supporting portion 220 is connected to the middle of the first section 211 in the vertical direction, so that the cross section of the first section 211 is T-shaped. Among them, the middle refers to the area between the two ends of the first section 211 in the vertical direction, and does not refer to the exact center of the first section 211. Therefore, the T-shape of the cross section may be symmetrical or asymmetrical. In other words, the portion of the first section 211 located above the supporting portion 220 and the portion of the first section 211 located below the supporting portion 220 may have equal or unequal lengths.

[0060] exist Figure 3In the illustrated embodiment, the covering portion 210 may be straight, and the support portion 220 and the covering portion 210 may form a T-shaped cross section of the edging strip 200. The edge of the cooker panel 100 is supported on the upper surface of the support portion 220, and the sealing strip 300 is arranged below the support portion 220 and located on the inner side of the covering portion 210. The T-shaped edging strip has a simple structure and low cost. In an embodiment not shown, the covering portion may not be straight, for example, the edging strip may have a Z-shaped cross section, and the covering portion of the edging strip covering the side surface of the cooker panel and the covering portion of the edging strip covering the sealing strip are connected by the support portion. The thickness of the covering portion 210 covering the side surface of the cooker panel 100 and the thickness of the covering portion 210 covering the side of the sealing strip 300 are both between 1mm-3mm, preferably, the thickness of the covering portion 210 is 1.5mm, which can take into account cost, beauty and strength. Similarly, the thickness of the support portion 220 may also be between 1 mm and 3 mm, preferably 1.5 mm.

[0061] In summary, in the above technical solution, the edge strip 200 can protect the easily damaged corners of the cooker panel 100. The sealing strip 300 is arranged on the inner side of the edge strip 200 or embedded in the bottom surface of the edge strip 200, so that the edge strip 200 can not only provide a certain protection for the cooker panel 100, but also provide a certain protection for the sealing strip 300, which can extend the service life of the sealing strip 300 and make the appearance more concise. Corresponding to different types of sealing strips 300, the bottom surface of the sealing strip 300 can also be flush with or protrude from the bottom surface of the edge strip 200, thereby providing the best sealing effect.

[0062] Exemplarily, the edging strip 200 may further include a protrusion 225, which extends downward from the support portion 220, and the protrusion 225 is spaced apart from the covering portion 210. The support portion 220, the protrusion 225 and the covering portion 210 may be enclosed to form a mounting groove 400, and the sealing strip 300 is embedded in the mounting groove 400. In this embodiment, the edging strip 200 and the countertop can completely enclose the sealing strip 300, and the sealing strip 300 is prevented from being damaged by external forces to the greatest extent. When the length of the protrusion 225 is equal to that of the covering portion 210, they can be supported on the countertop together, and the ability to withstand pressure is stronger. In some embodiments not shown, the protrusion may be longer than the covering portion, and when the cooker is installed on the countertop, the protrusion may extend into the installation opening to limit the cooker.

[0063] Exemplarily, the edge of the cooker panel 100 includes a plurality of straight edges 110 and a plurality of corners 120 connected between the plurality of straight edges 110. Along the direction of surrounding the steel plate 101, the covering portion 210 can be divided into a plurality of first sections 211 and a plurality of second sections 212. Among them: the plurality of first sections 211 respectively cover the side surfaces of the plurality of straight edges 110, the plurality of second sections 212 respectively cover the side surfaces of the plurality of corners 120, the plurality of second sections 212 are connected between the plurality of first sections 211, and the support portion 220 is arranged on the first section 211. Taking the common substantially rectangular cooker panel 100 as an example, the corner 120 of the cooker panel 100 can be processed into a rounded corner to avoid causing harm to the user during use. The portion of the edging strip 200 corresponding to the second section 212 is usually obtained by bending a profile. During the bending process, the large thickness of the support portion 220 in the bending direction will bring great inconvenience to the bending process. Therefore, the second section 212 may include the covering portion 210 without the support portion 220, and the covering portion 210 has a small thickness in the bending direction, which can be easily bent. The support portion 220 may be provided on the first section 211 to support the cooker panel 100. In some embodiments, the covering portion 210 of the first section 211 and the covering portion 210 of the second section 212 may be connected as one body, and being connected as one body may include being integrally formed and connected together by welding or the like. In other embodiments, the first section 211 and the second section 212 may be separated from each other.

[0064] As described above, the edge strip 200 is processed by bending, and usually the support portion 220 needs to be avoided. Therefore, illustratively, the ends 224 of the support portions 220 on adjacent first sections 211 are spaced apart from each other to form a notch 222, and the notch 222 is located inside the second section 212. This structure is relatively simple and the processing cost is lower.

[0065] Exemplarily, the end 224 of each support portion 220 is spaced apart from the inner side surface of the first segment 211 where it is located. Figure 5 and Figure 6In order to ensure that during the bending process, the material will not be squeezed and deformed to produce an uneven surface in the vertical direction to affect the assembly of the cooker panel 100, a spacing groove 221 can be provided at the end 224 of the support portion 220. When bending, the edge strip 200 can form a fillet with the same radius as the corner 120 of the cooker panel 100. Preferably, the spacing groove 221 is concentric with the bent fillet. In this way, during the bending process, almost only the first section 211 is bent, and the support portion 220 will not be deformed by the force during the bending. The width of the spacing groove 221 can be between 1.5mm and 4mm. The spacing groove 221 can extend to the connection between the first section 211 and the second section 212, and continue to extend 1mm-3mm in the direction of the first section 211, so as to ensure that during the bending process, the support portion 220 will not interfere with the inner surface of the second section 212. Ideally, the spacing groove 221 should be provided close to the inner surface of the second section 212. Considering the influence of processing accuracy, the spacing groove 221 is set at a distance of 0.2 mm from the inner surface of the second section 212, so as to prevent the second section 212 from being damaged and affecting the structural strength when processing the spacing groove 221.

[0066] Exemplarily, a glue groove 223 may be provided on the upper surface of the support portion 220. An adhesive may be provided in the glue groove 223, and the cooker panel 100 is fixed to the support portion 220 by the adhesive. When the edging strip 200 is installed together with the cooker panel 100, it is not easy to deform under external force. In order to avoid the cooker panel 100 and the edging strip 200 from being separated during transportation, or to avoid the cooker panel 100 and the edging strip 200 from being separated during installation and use, the cooker panel 100 and the support portion 220 may be bonded together by an adhesive. During use, the cooker panel 100 and the support portion 220 are bonded by an adhesive, and impurities such as oil stains may also be prevented from invading from the gap between the cooker panel 100 and the edging strip 200. The glue groove 223 may increase the contact area between the adhesive and the edging strip 200, and improve the bonding performance. The depth of the glue groove 223 may be between 0.4 mm and 1.5 mm, and preferably, the depth of the glue groove 223 may be 0.5 mm. In this way, both the strength of the support portion 220 and the amount of adhesive can be ensured. To ensure the strength of the adhesive and the strength of supporting the cooker panel 100, the width of the support portion 220 can be between 5mm and 15mm. Preferably, the width of the support portion 220 can be 7mm.

[0067] Exemplarily, the adhesive groove 223 extends to the end 224 of the support portion 220. In this way, a bonding area as large as possible can be formed between the cooker panel 100 and the edge strip 200, and the bonding effect is better.

[0068] For example, along the extension direction of the edging strip 200, the end 224 of each support portion 220 protrudes from the first section 211 where it is located. In this way, the edging strip 200 can be bonded to the corner 120 of the cooker panel 100 and can also provide support for the corner 120 of the cooker panel 100.

[0069] Exemplarily, the width of the notch 222 is between 0.5 mm and 2 mm. If the notch 222 is too large, since the corner 120 of the cooker panel 100 corresponds to the notch 222, the cooker panel 100 and the edging strip 200 cannot be bonded together by adhesive at the notch 222, which may cause the cooker panel 100 and the edging strip 200 to be loosely bonded at the corner 120. If the notch 222 is too small, the support portions 220 on both sides of the notch 222 may interfere with each other. In the case where the edging strip 200 is bent using a profile, the position corresponding to the corner 120 of the cooker panel 100 cannot be bent to a corresponding angle of, for example, 90 degrees. Therefore, a reasonable setting of the size of the notch 222 can ensure that the cooker panel 100 and the edging strip 200 are reliably bonded, and the structure is simple.

[0070] Exemplarily, the upper surface of the edge strip 200 is not higher than the upper surface of the first plastic powder spray coating 105. It is understandable that if the upper surface of the edge strip 200 is higher than the upper surface of the first plastic powder spray coating 105, when cleaning the stove panel 100, oil stains and other debris will be blocked by the edge strip 200 and remain on the upper surface of the stove panel 100, and most of them will accumulate in the gap between the edge strip 200 and the stove panel 100. When subjected to external force, the external force may also act on the edge strip 200, causing the edge strip 200 to separate from the side surface of the stove panel 100 and lose its protective function. Ideally, the upper surface of the edge strip 200 is completely flush with the stove panel 100. Due to the limitation of processing accuracy, preferably, the edge strip 200 is slightly lower than the upper surface of the stove panel 100, so that when cleaning the stove panel 100, the stains will not be blocked by the edge strip 200 and accumulated, and the processing accuracy requirements can be reduced, and the cost can be reduced. During use, the edge strip 200 is not easily separated from the side surface of the cooker panel 100 by an external force directed away from the side surface of the cooker panel 100. Preferably, the upper surface of the edge strip 200 may be 0.5 mm lower than the upper surface of the cooker panel 100. In the embodiment where the cooker panel 100 is chamfered or rounded, the edge of the cooker panel 100 may form a relatively smooth transition with the upper surface of the edge strip 200.

[0071] like Figure 7As shown, illustratively, there is one edging strip 200, and the joint 201 between the two ends of the edging strip 200 is located at the straight edge 110 of the steel plate 101. By using one edging strip 200 to surround the steel plate 101, only one joint 201 can be generated. In the actual production process, a straight profile is bent to form a structure surrounding the stove panel 100, which has a lower processing cost, a simple structure and a higher yield rate. Exemplarily, the support portion 220 is located at the two ends of the edging strip and is provided with a glue overflow hole 202, which allows the adhesive to better contact with the air to accelerate curing.
