Description

Technical Field

[0001] This utility model relates to a gas stove. Background Technology

[0002] To achieve higher heat load and thermal efficiency, existing gas stoves are all equipped with a heat-concentrating hood. Currently, commonly used heat-concentrating hoods include single-layer, double-layer, and even multi-layer hoods. At the same time, a drip tray is installed below the burner to collect liquids overflowing from the cookware. However, in existing gas stoves, the heat-concentrating hood and the drip tray are separate components and do not work together, resulting in lower combustion efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a gas stove.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A gas stove includes a burner, a liquid collection tray, and an energy-concentrating cover. The upper surface of the liquid collection tray has an annular protrusion surrounding the center. The edge of the annular protrusion has a first annular inclined surface that slopes inward from bottom to top. The inner side of the lower surface of the energy-concentrating cover has a second annular inclined surface that slopes inward from bottom to top. The second annular inclined surface is parallel to the first annular inclined surface. The first annular inclined surface and the second annular inclined surface form an outlet for a secondary air supply channel, and the outlet faces the burner's flame port.

[0006] In this design, the gas stove uses a liquid collection tray in conjunction with an energy-concentrating hood. The first annular inclined surface of the liquid collection tray and the second annular inclined surface of the energy-concentrating hood form the outlet of a secondary air supply channel. This outlet faces the burner's flame holes, ensuring that most of the secondary air is accurately delivered to the burner, improving combustion efficiency. Furthermore, by arranging the first and second annular inclined surfaces parallel to each other, the axial direction of the secondary air supply channel faces the burner's flame holes. This guides the secondary air to the flame holes, ensuring precise delivery to the flame root, further enhancing combustion efficiency and significantly reducing smoke emissions. The annular protrusion on the liquid collection tray and the first annular inclined surface guide overflow outwards, reducing overflow accumulation and preventing it from affecting the burner.

[0007] Preferably, the secondary air supply channel is formed by the energy-concentrating hood and the liquid-collecting tray, the inlet of the secondary air supply channel is located on the outer periphery of the energy-concentrating hood, and the inner diameter of the secondary air supply channel gradually decreases and then increases along the airflow direction.

[0008] In this scheme, the above-mentioned structural setting is adopted to form a Venturi structure in the secondary air supply channel. When the air flows in the secondary air supply channel, it is accelerated by the Venturi structure so that more secondary air flows to the burner position, so that the gas combustion is complete.

[0009] Preferably, the edge of the annular boss is provided with a groove, the groove passes through the first annular inclined surface, and at least three grooves are spaced apart along the circumferential direction of the annular boss. The groove is used to embed the support legs of the pot support.

[0010] In this design, the groove passes through the first annular inclined surface, which increases the length of the groove and increases the fit length between the pot support leg and the groove, thereby enhancing the ease of placement of the pot support and reducing the risk of the leg coming off.

[0011] Preferably, the liquid-holding tray has a through hole in the middle, through which the burner passes.

[0012] In this design, the above-mentioned structure allows the upper burner cap to be exposed, while also facilitating the covering of the lower mixing chamber of the burner with the liquid collection tray.

[0013] Preferably, the liquid collection tray has mounting holes, and a plurality of mounting holes are arranged around the periphery of the through hole, the mounting holes being used to mount the liquid collection tray to the burner.

[0014] In this design, fasteners can be connected to the burner through mounting holes, thus fixing the liquid tray to the burner and improving stability.

[0015] Preferably, the inner side of the liquid tray has a lug protruding towards the center of the through hole, the lug being used to engage with a groove on the outer peripheral surface of the burner.

[0016] In this design, when installing the liquid collection tray, aligning the lugs of the tray with the burner recess allows for quick alignment and improves installation speed. When the lugs engage within the recess, they also prevent the liquid collection tray from rotating relative to the burner, enhancing the connection.

[0017] Preferably, there are multiple lugs, and the multiple lugs are spaced apart along the circumferential direction of the liquid-holding tray.

[0018] In this solution, the above-mentioned structural design can improve the fixation effect of the liquid tray and the burner.

[0019] Preferably, the lugs are provided in a one-to-one correspondence with the mounting holes, and the mounting holes are provided on the lugs.

[0020] In this design, the aforementioned structural arrangement makes the entire device compact and saves installation space. When the liquid tray is installed using screws, the mounting holes on the lugs ensure that the screw receiving surface is circumferentially intact and reliably stressed.

[0021] Preferably, both sides of the lug are chamfered.

[0022] In this solution, the above-mentioned structural design ensures that there are no sharp points on the inner boundary of the liquid-holding tray, avoiding stress concentration caused by edge effects and reducing the risk of porcelain cracking of the liquid-holding tray.

[0023] Preferably, the liquid-holding tray is a disc, and the disc has downwardly sloping flanges around its four edges.

[0024] In this solution, the above-mentioned structural design allows the flange to connect more tightly with the cooktop panel, preventing spillage from entering the lower cavity of the drip tray and quickly guiding the spillage away from the burner, thus protecting the burner and internal components.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0026] The significant advantages of this invention are as follows: The gas stove uses a liquid collection tray in conjunction with an energy-concentrating hood. The first annular inclined surface of the liquid collection tray and the second annular inclined surface of the energy-concentrating hood form the outlet of a secondary air supply channel. This outlet faces the burner's flame holes, allowing most of the secondary air to be accurately delivered to the burner, improving combustion efficiency. Furthermore, by arranging the first and second annular inclined surfaces parallel to each other, with the axial direction of the secondary air supply channel facing the burner's flame holes, the secondary air is guided to the flame holes, ensuring precise delivery to the flame root and significantly reducing smoke emissions, further enhancing combustion efficiency. The annular protrusion and the first annular inclined surface on the liquid collection tray guide overflow outwards, reducing overflow accumulation and preventing overflow from affecting the burner.

[0047] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0048] like Figures 1-5As shown in the figure, this embodiment discloses a gas stove, which includes a burner (not shown in the figure), a liquid tray 1 and an energy-concentrating cover 2. The upper surface of the liquid tray 1 has an annular protrusion 11 surrounding the center. The edge of the annular protrusion 11 has a first annular inclined surface 12 that slopes inward from bottom to top. The inner side of the lower surface of the energy-concentrating cover 2 has a second annular inclined surface 21 that slopes inward from bottom to top. The second annular inclined surface 21 is parallel to the first annular inclined surface 12. The first annular inclined surface 12 and the second annular inclined surface 21 form the outlet 31 of the secondary air supply channel 3. The outlet 31 faces the burner's flame hole position. This gas stove uses a liquid collection tray 1 in conjunction with an energy-concentrating cover 2. The first annular inclined surface 12 of the liquid collection tray 1 and the second annular inclined surface 21 of the energy-concentrating cover 2 form the outlet 31 of the secondary air supply channel 3. The outlet 31 faces the burner's flame holes, allowing most of the secondary air to be accurately delivered to the burner, improving combustion efficiency. Furthermore, by arranging the first annular inclined surface 12 and the second annular inclined surface 21 parallel to each other, with the axis of the secondary air supply channel 3 facing the burner's flame holes, the secondary air is guided to the flame holes, enabling precise delivery to the flame root, significantly reducing smoke and further improving combustion efficiency. The annular protrusion 11 and the first annular inclined surface 12 on the liquid collection tray 1 guide overflow outwards, reducing overflow accumulation and preventing overflow from affecting the burner.

[0049] like Figure 3 As shown, preferably, in this embodiment, the first annular inclined surface 12 and the second annular inclined surface 21 are connected end to end, and a part of the first annular inclined surface 12 is located upstream of the second annular inclined surface 21. After the secondary air flows to the first annular inclined surface 12, it is guided to flow in an upward direction. After the upward air flows to the second annular inclined surface 21, it is guided to the fire hole position, thereby improving the secondary air replenishment effect.

[0050] like Figure 3 As shown, the secondary air supply channel 3 is surrounded by the energy-concentrating cover 2 and the liquid-holding tray 1. The inlet 32 ​​of the secondary air supply channel 3 is located on the outer periphery of the energy-concentrating cover 2. The inner diameter of the secondary air supply channel 3 gradually decreases and then increases along the airflow direction, forming a Venturi structure. When the air flows in the secondary air supply channel 3, it is accelerated by the Venturi structure so that more secondary air flows to the burner hole position, allowing the gas to burn completely.

[0051] The outer side of the energy-concentrating cover 2 forms a funnel shape to facilitate the collection of more air.

[0052] Preferably, the inclination angles of the first annular inclined surface 12 and the second annular inclined surface 21 are both 40°, they are parallel and 3mm apart, forming the outlet of the secondary air supply channel.

[0053] like Figure 4As shown, the annular boss 11 has a groove 13 on its edge, which passes through the first annular inclined surface 12. At least three grooves 13 are spaced apart along the circumferential direction of the annular boss 11. The grooves 13 are used to embed the legs of the pot support. The grooves 13 extend radially and pass through the first annular inclined surface 12, which increases the length of the grooves 13, thereby increasing the fit length between the legs of the pot support and the grooves 13. This enhances the ease of placement of the pot support, reduces the risk of the legs coming off, and improves safety.

[0054] like Figure 4 As shown, the liquid collection tray 1 has a through hole 14 in the middle. The burner passes through the through hole 14, which makes it easy to expose the upper flame cap of the burner. At the same time, it is also easy for the liquid collection tray 1 to cover the lower mixing chamber of the burner and protect the lower part of the burner.

[0055] like Figure 4 and Figure 5 As shown, the liquid collection tray 1 has mounting holes 15, and multiple mounting holes 15 are arranged around the periphery of the through hole 14. The mounting holes 15 are used to install the liquid collection tray 1 onto the burner. Fasteners are connected to the burner through the mounting holes 15, so that the liquid collection tray 1 is fixed on the burner and the stability is improved.

[0056] like Figure 4 and Figure 5 As shown, the inner side of the liquid collection tray 1 has a lug 16 protruding towards the center of the through hole 14. The lug 16 is used to engage with the groove 13 on the outer peripheral surface of the burner. When installing the liquid collection tray 1, aligning the lug 16 of the liquid collection tray 1 with the groove 13 of the burner can achieve quick alignment of the liquid collection tray 1 and improve the installation speed. When the lug 16 is engaged in the groove 13, it can also prevent the liquid collection tray 1 from rotating relative to the burner, thus improving the connection effect.

[0057] In this embodiment, there are multiple lugs 16, which are spaced apart along the circumferential direction of the liquid-filled tray 1, thereby improving the fixing effect of the liquid-filled tray 1 and the burner.

[0058] In this embodiment, there are four lugs 16, which are evenly spaced along the circumferential direction of the liquid tray 1.

[0059] In this embodiment, the lugs 16 and mounting holes 15 are provided in a one-to-one correspondence. The mounting holes 15 are provided on the lugs 16, making the entire device structure compact and saving installation space. When the liquid tray 1 is fixed with screws, the mounting holes 15 on the lugs 16 also ensure that the screw bearing surface is circumferentially complete and the force is reliable.

[0060] like Figure 4 and Figure 5 As shown, both sides of the lug 16 are chamfered 17, so that there are no sharp points on the inner edge of the liquid holding tray 1, avoiding stress concentration caused by edge effect and reducing the risk of porcelain cracking of the liquid holding tray 1.

[0061] In this embodiment, the liquid collection tray 1 is a disc with downwardly sloping flanges 18 around its four edges. The flanges 18 can connect more tightly to the stove panel, preventing spillage from entering the lower cavity of the liquid collection tray 1 and quickly guiding the spillage away from the burner, thus protecting the burner and internal components.

[0062] This embodiment also discloses a smart appliance, which includes the gas stove described above. The smart appliance is equipped with a smart voice control module, which includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller can open the solenoid valve on the gas pipe and turn on the ignition switch, thus turning on the burner. The controller can also close the solenoid valve on the gas pipe, cutting off the gas supply, and turning off the burner, based on the parsed commands.
