The pot rack is arranged around the outside of the burners, and both the pot rack and burners are placed on the control panel. The pot rack has multiple feet to support the cookware. The flame generated by the burners heats the cookware.
[0003] However, during the use of a gas stove, soup or stains may flow onto the panel, making cleaning the gas stove rather inconvenient. Utility Model Content
[0004] Based on this, this application provides a burner assembly and a gas stove to solve the problem in the related art that during the use of a gas stove, soup or stains may flow onto the panel, making the cleaning of the gas stove inconvenient.
[0005] In a first aspect, embodiments of this application provide a burner assembly, including:
[0006] The pot rack includes a support and feet. The support includes a mounting part and a supporting part. The supporting part surrounds the outside of the mounting part and is fixedly connected to the mounting part. The inner edge of the supporting part is in close contact with the outer edge of the mounting part. The feet are mounted on the supporting part.
[0007] The flame cap is installed on the mounting section;
[0008] The top surface of the support includes a drying surface, a guide surface, and a receiving surface. The drying surface surrounds the outside of the mounting part and is in contact with the mounting part. The guide surface surrounds the outside of the drying surface and is in contact with the drying surface. The receiving surface surrounds the outside of the guide surface and is in contact with the guide surface.
[0009] The heat at the burner can be transferred sequentially to the drying surface, the guide surface, and the receiving surface. The guide surface is configured to guide the liquid flowing out from the drying surface to the receiving surface.
[0010] In one possible implementation, the guide surface is inclined to the horizontal plane, and the height of the guide surface gradually decreases from the inner edge to the outer edge of the guide surface.
[0011] In one possible implementation, the drying surface is inclined to the horizontal plane, and the height of the drying surface gradually decreases from the inner edge to the outer edge of the drying surface. The angle between the guide surface and the horizontal plane is greater than the angle between the drying surface and the horizontal plane.
[0012] In one possible implementation, the angle between the drying surface and the horizontal plane is 10°-30°, and the angle between the guide surface and the horizontal plane is less than or equal to 70°.
[0013] In one possible implementation, the receiving surface is inclined to the horizontal plane, and the height of the receiving surface gradually increases from the inner edge to the outer edge of the receiving surface, with the angle between the receiving surface and the horizontal plane being less than or equal to 15°.
[0014] In one possible implementation, an annular protrusion is provided on the bearing surface, the annular protrusion being located at the outer edge of the bearing surface and arranged around the center of the bearing surface.
[0015] In one possible implementation, the height of the annular protrusion is 2mm-5mm.
[0016] In one possible implementation, the drying surface is annular, and the flow guiding surface includes multiple guiding surfaces and multiple transition surfaces. The multiple guiding surfaces are arranged in a circular array around the axis of the flame cap, and the transition surfaces connect adjacent guiding surfaces. Along the circumference of the flame cap, each transition surface is opposite to a foot piece. The outer periphery of the flow guiding surface is polygonal, and the foot piece is located at the corner of the polygon.
[0017] Along the circumference of the flame cap, the shape of the area corresponding to the receiving surface and each guide surface is consistent. In one possible implementation, the bottom of the support is provided with a support leg, and the projection of the support leg in the vertical direction lies on the receiving surface.
[0018] Secondly, embodiments of this application provide a gas stove, including a panel and the aforementioned burner assembly, the burner assembly being placed on the panel.
[0019] This application provides a burner assembly and a gas stove. The burner assembly includes a pot rack and a burner cap. The pot rack includes a support and feet. The support includes a mounting part and a supporting part, and the burner cap is mounted on the mounting part. The mounting part can function as the base of a conventional burner, integrating the base of a conventional burner onto the support of the pot rack. The supporting part surrounds the outside of the mounting part and is fixedly connected to it, and the feet are mounted on the supporting part. The top surface of the supporting part includes a drying surface, a guide surface, and a receiving surface, which are arranged sequentially around the outside of the mounting part. The heat generated by the flame burning at the burner cap can be sequentially transferred to the drying surface, the guide surface, and the receiving surface.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] In existing technology, gas stoves generally include a control panel, a burner, and a pot rack. The pot rack is arranged around the outside of the burner, and both the pot rack and the burner are placed on the control panel. The pot rack has multiple feet to support the cookware. The flame generated by the burner heats the cookware. However, because the burner and pot rack are separate units with a gap between them, liquids such as water and soup from the bottom of the cookware can easily flow from between the burner and the pot rack onto the control panel, making cleaning the gas stove inconvenient.
[0036] After repeated consideration and verification, the inventors discovered that if the pot rack support and the burner base are integrated together, the pot rack support includes a mounting part and a support part surrounding the outside of the mounting part. The burner cap is installed on the mounting part. The top surface of the support part includes a drying surface, a guide surface, and a receiving surface arranged sequentially around the outside of the mounting part. The heat of the flame at the burner cap can be sequentially transferred to the drying surface, the guide surface, and the receiving surface, so that the drying surface, the guide surface, and the receiving surface can all heat the liquid on them. The guide surface can guide the liquid flowing out of the drying surface to the receiving surface, and the receiving surface can collect the unevaporated liquid and impurities in the liquid. The liquid will not flow from the top surface of the support part to the gas stove panel, keeping the panel clean.
[0037] In view of this, the inventors designed a burner assembly and a gas stove. An mounting part and a support part are provided on the pot holder support. The burner cap is mounted through the mounting part. The top surface of the support part includes a drying surface, a guide surface, and a receiving surface arranged sequentially around the outside of the mounting part. The drying surface, guide surface, and receiving surface are divided into three zones on the top surface of the support part. The heat from the flame at the burner cap can be sequentially transferred to the drying surface, guide surface, and receiving surface. The drying surface can quickly evaporate the moisture on it. The guide surface can direct the liquid flowing from the drying surface to the receiving surface and further assist in drying the moisture on it. The receiving surface can collect unevaporated liquid and impurities in the liquid and further assist in drying the moisture on it. Liquid will not flow from the top surface of the support part to the gas stove panel, keeping the gas stove panel dry.
[0038] The technical solutions of the burner assembly and gas stove provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0039] Reference Figures 1 to 4 As shown in the embodiment of this application, the burner assembly includes a pot frame 100 and a burner cap 200.
[0040] The pot rack 100 includes a support 110 and feet 120. The support 110 includes a mounting portion 111 and a supporting portion 112. The supporting portion 112 surrounds the outside of the mounting portion 111 and is fixedly connected to the mounting portion 111. The inner edge of the supporting portion 112 is in close contact with the outer edge of the mounting portion 111. The feet 120 are mounted on the supporting portion 112.
[0041] Optionally, the mounting part 111 and the support part 112 can be fixed by fasteners, or the mounting part 111 and the support part 112 can be integrally formed. Multiple feet 120 are provided to support the cookware 20.
[0042] The burner cap 200 is mounted on the mounting part 111. Understandably, the mounting part 111 of the support 110 can function as the base of the burner in the prior art, integrating the base of the burner onto the support 110 of the boiler frame 100, which facilitates the installation and maintenance of the burner assembly.
[0043] The top surface of the support portion 112 includes a drying surface 113, a guide surface 114, and a receiving surface 115. The drying surface 113 surrounds the outside of the mounting portion 111 and is in contact with the mounting portion 111. The guide surface 114 surrounds the outside of the drying surface 113 and is in contact with the drying surface 113. The receiving surface 115 surrounds the outside of the guide surface 114 and is in contact with the guide surface 114. That is to say, the drying surface 113, the guide surface 114, and the receiving surface 115 are arranged sequentially around the outside of the mounting portion 111, defining three functional areas from the inside to the outside of the mounting portion 111.
[0044] The heat from the flame at the burner cap 200 can be sequentially transferred to the drying surface 113, the guide surface 114, and the receiving surface 115. The guide surface 114 is configured to guide the liquid flowing from the drying surface 113 to the receiving surface 115. The pot frame 100 is made of metal, and the heat from the flame at the burner cap 200 can be sequentially transferred to the drying surface 113, the guide surface 114, and the receiving surface 115. When the flame at the burner cap 200 is burning, the drying surface 113, the guide surface 114, and the receiving surface 115 are all heated, with the heat of the drying surface 113 being greater than that of the guide surface 114, and the heat of the guide surface 114 being greater than that of the receiving surface 115.
[0045] It should be noted that the drying surface 113, as a high-temperature drying water zone, utilizes the high temperature generated by the flame at the burner cap 200 to quickly evaporate moisture on it. When the flame at the burner cap 200 releases heat, the drying surface 113, located on the top surface of the support 112 and connected to the mounting part 111, directly contacts the heat released by the flame. The high temperature generated by the flame is rapidly transferred to the drying surface 113, causing its surface temperature to rise rapidly. This high-temperature design of the drying surface 113 allows water and liquids such as soup at the bottom of the cookware 20 to evaporate quickly after flowing onto the drying surface 113, reducing the amount of liquid flowing outward to the guide surface 114. Due to the high temperature of the drying surface 113, food residue that falls onto it can be gradually carbonized, making it easier to clean.
[0046] The guide surface 114 serves as a liquid drainage zone, guiding the liquid to flow smoothly and preventing accumulation. When water, soup, or food residue from the cookware 20 falls onto the guide surface 114 or the liquid on the drying surface 113 flows onto the guide surface 114, the guide surface 114 directs the liquid to the receiving surface 115. The liquid flows quickly on the guide surface 114 and does not linger there, preventing the accumulation of liquid and impurities on the guide surface 114 over a large area. Furthermore, the heat generated by the flame at the burner cap 200 can be transferred to the guide surface 114 via the drying surface 113, further assisting in drying the liquid on it.
[0047] The receiving surface 115 serves as a secondary drying and sedimentation zone for liquids. It collects liquids flowing from the guide surface 114, further treating the moisture in the liquids and collecting residues. In one possible implementation, the receiving surface 115 can be a plane parallel to the horizontal plane. When liquids flow from the guide surface 114 to the receiving surface 115, they undergo secondary drying and sedimentation on the receiving surface 115. The receiving surface 115 effectively collects liquids and food residues flowing down from the guide surface 114, facilitating cleaning and preventing further dripping onto the gas stove panel, keeping the panel clean. The heat generated by the flame at the burner cap 200 is also transferred to the receiving surface 115, further evaporating the moisture in the liquids thereon and drying the residues for easy cleaning.
[0048] The burner assembly provided in this embodiment has a pot holder 100 mounting portion 111 that functions as a base for a traditional burner, integrating the base of a traditional burner onto the support 110 of the pot holder 100. The heat generated by the flame at the burner cap 200 is sequentially transferred to the drying surface 113, the guide surface 114, and the receiving surface 115. When water and liquids such as soup from the bottom of the pot 20 flow to the top surface of the support portion 112, the drying surface 113, the guide surface 114, and the receiving surface 115 can all heat the liquid, causing it to evaporate. The guide surface 114 guides the liquid flowing from the drying surface 113 towards the receiving surface 115, which collects any unevaporated water and impurities such as food residue, facilitating cleaning. The liquid on the top surface of the support portion 112 can be evaporated, and the food residue on the top surface of the support portion 112 can be carbonized, simplifying the cleaning process, reducing stubborn stains, and improving the self-cleaning ability of the burner assembly. Liquid will not flow from the top surface of the support 112 to the gas stove panel, keeping the panel clean.
[0049] In existing technologies, the burner and pot support 100 are arranged separately, which is cumbersome to remove and put away. After cleaning, it is easy to misplace them, which can easily lead to damage during combustion. The burner assembly provided in this embodiment integrates the base of the traditional burner onto the support 110 of the pot support 100. The burner assembly is easier to remove, place, and maintain, and it is easy to position correctly, resulting in higher reliability. The burner assembly has a simple structure and is suitable for various scenarios such as home and commercial kitchens.
[0050] like Figure 4 As shown, during combustion, the secondary air required by the burner assembly flows in the direction indicated by the arrow. The secondary air first contacts the receiving surface 115, then is guided by the guide surface 114 to the drying surface 113, and finally supplied to the burner cap 200 via the drying surface 113. The secondary air required for combustion passes through the three surfaces of the boiler frame 100. The auxiliary heating effect of the receiving surface 115, guide surface 114, and drying surface 113 during combustion provides a certain degree of heating to the secondary air, thus preventing the impact of sudden changes in cold air on combustion thermal efficiency. Therefore, it has a certain effect on improving combustion efficiency and heat utilization, resulting in energy saving and environmental protection.
[0051] In one embodiment, such as Figures 1-4 As shown, the guide surface 114 is inclined to the horizontal plane, and the height of the guide surface 114 gradually decreases from the inner edge to the outer edge of the guide surface 114.
[0052] A sloped surface 114 can be used as the guide surface, sloping downwards from the inside out. The top end of the guide surface 114 is in contact with the drying surface 113, and the bottom end of the guide surface 114 is in contact with the receiving surface 115. When liquid on the drying surface 113 flows to the guide surface 114, or when liquid or food residue in the cookware 20 falls onto the guide surface 114, the liquid or food residue on the guide surface 114 can flow downwards on the guide surface 114, and unevaporated liquid and food residue can flow onto the receiving surface 115.
[0053] This structure uses a sloped surface as the guide surface 114, and the angle of the slope of the guide surface 114 can guide the liquid and food residue on it to flow downwards. In addition, the guide surface 114 is relatively easy to process, which helps to reduce the production cost of the burner assembly. It also facilitates the cleaning of the guide surface 114.
[0054] In other embodiments, an arc surface can be used as the guide surface 114, with the height of the arc surface gradually decreasing from its inner edge to its outer edge. The arc surface can guide liquid and food residue on it to flow downwards.
[0055] In a specific embodiment, such as Figures 1-4As shown, the drying surface 113 is inclined to the horizontal plane. From the inner edge of the drying surface 113 to the outer edge of the drying surface 113, the height of the drying surface 113 gradually decreases. The angle between the guide surface 114 and the horizontal plane is greater than the angle between the drying surface 113 and the horizontal plane.
[0056] The drying surface 113 can be an inclined plane, sloping downwards from the inside out. When liquid falls onto the drying surface 113, the liquid on the drying surface 113 can flow towards the guide surface 114 due to the inclined angle, preventing liquid from accumulating on the drying surface 113. The drying surface 113 is gentler than the guide surface 114, and the flow speed of liquid on the drying surface 113 is lower than that on the guide surface 114. Liquid and food residue can remain on the drying surface 113 for a certain period of time, facilitating rapid evaporation of moisture on the drying surface 113 and reducing liquid accumulation on the receiving surface 115. The guide surface 114 is steeper than the drying surface 113, allowing liquid on the guide surface 114 to flow smoothly and preventing accumulation.
[0057] like Figure 4 As shown, the receiving surface 115, the guiding surface 114, and the drying surface 113 can guide secondary air to flow upward to the flame cap 200, facilitating secondary air intake of the flame at the flame cap 200.
[0058] In a more specific embodiment, such as Figure 3 As shown, the angle α between the drying surface 113 and the horizontal plane is 10°-30°, and the angle β between the guide surface 114 and the horizontal plane is less than or equal to 70°.
[0059] For example, the value of α can be 10°, 15°, 20°, 25°, or 30°, etc., and is not limited to a single value. When the angle between the drying surface 113 and the horizontal plane is less than 10°, the drying surface 113 is too flat, and liquid tends to accumulate on the drying surface 113. When the angle between the drying surface 113 and the horizontal plane is greater than 30°, the height difference between the drying surface 113 and the flame on the flame cap 200 is large, and the heat of the flame is not easily transferred to the drying surface 113, affecting the drying effect of the drying surface 113 on the liquid.
[0060] Optionally, the angle β between the guide surface 114 and the horizontal plane can be between 31° and 70°. When the angle between the guide surface 114 and the horizontal plane is greater than 70°, on the one hand, given a fixed height, the width of the guide surface 114 is relatively small; on the other hand, the flow velocity of the liquid on the guide surface 114 is too fast. These reasons result in a smaller auxiliary drying effect of the guide surface 114 on the liquid.
[0061] In other words, by limiting the angle between the drying surface 113 and the horizontal plane, liquid accumulation on the drying surface 113 is prevented, while the drying surface 113 can better receive the heat from the flame at the burner cap 200, ensuring the drying effect of the drying surface 113 on the liquid. By limiting the angle between the guide surface 114 and the horizontal plane, the auxiliary drying effect of the guide surface 114 on the liquid can be ensured.
[0062] In one embodiment, the receiving surface 115 is inclined to the horizontal plane, and the height of the receiving surface 115 gradually increases from the inner edge to the outer edge of the receiving surface 115. The angle between the receiving surface 115 and the horizontal plane is less than or equal to 15°.
[0063] Schematic illustration: The receiving surface 115 can be a sloped surface, sloping upwards from the inside out. Using a sloped surface as the receiving surface 115 prevents liquids and food residues on it from flowing outwards onto the gas stove panel, keeping the panel clean. For example, the angle between the receiving surface 115 and the horizontal plane can be 5°, 10°, or 15°, etc., and is not limited to a single angle. When the angle between the receiving surface 115 and the horizontal plane is greater than 15°, the outer edge of the receiving surface 115 is higher, which will obstruct secondary air intake of the flame on the burner cap 200 and make cleaning the receiving surface 115 more difficult.
[0064] The above settings prevent liquids and food residues on the receiving surface 115 from flowing outwards onto the gas stove panel, while also ensuring secondary air intake for the flame on the burner cap 200 and facilitating cleaning of the receiving surface 115.
[0065] like Figure 5 As shown, in one embodiment, an annular protrusion 116 is provided on the receiving surface 115, the annular protrusion 116 is located on the outer edge of the receiving surface 115 and arranged around the center of the receiving surface 115.
[0066] The annular protrusion 116 can be integrally formed on the support part 112. The shape of the annular protrusion 116 can match the shape of the outer edge of the receiving surface 115. The annular protrusion 116 can prevent liquid and food residue on the receiving surface 115 from flowing out of the receiving surface 115, ensuring the cleanliness of the gas stove panel.
[0067] Indicatively, the height of the annular protrusion 116 is 2mm-5mm.
[0068] The height of the annular protrusion 116 can be 2mm, 3mm, 4mm, or 5mm, etc., and is not limited to one. When the height of the annular protrusion 116 is less than 2mm, the annular protrusion 116 has a small blocking effect on the liquid on the receiving surface 115; when the height of the annular protrusion 116 is greater than 5mm, the annular protrusion 116 will obstruct the secondary air intake of the flame on the flame cap 200.
[0069] In other words, by limiting the height of the annular protrusion 116, the blocking effect of the annular protrusion 116 on the liquid on the receiving surface 115 is ensured, while the secondary air intake of the flame on the flame cap 200 is also ensured.
[0070] like Figure 1 and Figure 2 As shown, the drying surface 113 is annular, meaning that the drying surface 113 has a consistent width in the circumferential direction of the flame cap 200. For example, the width of the drying surface 113 can be 5mm-10mm.
[0071] The guide surface 114 includes multiple guide surfaces 1141 and multiple transition surfaces 1142. The multiple guide surfaces 1141 are arranged in a ring array around the axis of the flame cap 200, and the transition surfaces 1142 connect adjacent guide surfaces 1141. For example, as shown... Figure 1 and Figure 2 As shown, the outer edge of the guide surface 114 can be quadrilateral. The number of guide surfaces 1141 and transition surfaces 1142 can each be four. The four guide surfaces 1141 are located on the sides of the quadrilateral, and the four guide surfaces 114 are located at the apex of the quadrilateral. The guide surface 1141 can be an inclined surface that gradually descends away from the drying surface 113. The transition surface 1142 can be an arc surface, with two guide surfaces 1141 connected to opposite sides of the arc surface, and the arc surface gradually descends away from the drying surface 113.
[0072] Along the circumference of the flame cap 200, each transition surface 1142 is opposite a foot piece 120. The outer periphery of the guide surface 114 is polygonal, and the foot piece 120 is located at the corner of the polygon. Figure 1 and Figure 2 As shown, when the outer edge of the guide surface 114 is quadrilateral, there are four foot pieces 120, which are located at the four vertices of the quadrilateral. Along the circumference of the flame cap 200, the shape of the receiving surface 115 is consistent with the shape of the area corresponding to each guide surface 1141.
[0073] In this embodiment, when a flame is burning at the burner cap 200, secondary air can flow evenly from the circumference of the burner cap 200 to the burner cap 200, optimizing the airflow distribution of the burner assembly. The secondary airflow required for combustion is evenly distributed through the receiving surface 115, the guiding surface 114, and the drying surface 113 of the pot rack 100. During combustion, the heat and airflow generated by the burner assembly are evenly distributed through the three surfaces of the pot rack 100, improving combustion efficiency and heat utilization, reducing energy waste, and ensuring cooking results.
[0074] Schematic, the bottom of the support 112 is provided with a support leg 117, and the projection of the support leg 117 in the vertical direction is located on the receiving surface 115.
[0075] The top of the support leg 117 is connected to the bottom of the support part 112, and the support leg 117 and the support part 112 can be formed into a single piece through an integral molding process. There are multiple support legs 117, and the burner assembly is placed on the gas stove panel through multiple support legs 117. The support legs 117 create a gap between the support 110 of the pot rack 100 and the panel to achieve "upward air intake".
[0076] Understandably, when there is a flame burning at the burner cap 200, the heat at the support part 112 located at the bearing surface 115 is lower, and the projection of the support leg 117 in the vertical direction is located on the bearing surface 115, which can prevent excessive heat from being transferred to the support leg 117 and then from the support leg 117 to the panel, thus avoiding damage to the panel.
[0077] This application also provides a gas stove, including a panel and the aforementioned burner assembly, the burner assembly being placed on the panel.
[0078] The gas stove provided in this application, by using the aforementioned burner components, can ensure a clean panel during cooking, thus improving the user experience.
[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
