Description

Technical Field

[0001] This utility model belongs to the field of stove technology, specifically providing a gas stove and its combustion module. Background Technology

[0002] Gas stoves are kitchen appliances that use liquefied petroleum gas (liquid), manufactured gas, natural gas, or other gaseous fuels for direct-fire heating and are used by many families.

[0003] With continuous technological advancements, gas stoves are constantly being updated and replaced. However, these updates often only optimize functional components such as the burner, flame caps, pot supports, and drip trays, while the base is typically left untouched. Consequently, when replacing a gas stove, users usually need to replace the entire unit, which is not only costly but also wastes resources. Utility Model Content

[0004] One objective of this invention is to solve the problem of high replacement costs for existing gas stoves.

[0005] To achieve the above objectives, the present invention provides a combustion module for a gas stove in a first aspect, comprising:

[0006] The bottom shell has a plug-in boss on one side in the horizontal direction, so that the bottom shell can be plugged into the base of the gas stove by means of the plug-in boss;

[0007] The burner head is disposed inside the bottom shell and fixedly connected to the bottom shell;

[0008] An air inlet pipe has its air inlet end fixedly connected to the plug-in boss, so that the air inlet of the air inlet pipe is formed on the plug-in boss; the air outlet end of the air inlet pipe is connected to the burner head, so that the gas is introduced into the burner head through the air inlet pipe.

[0009] A pot rack cover is installed on the bottom shell to cover the internal space of the bottom shell. The pot rack cover is provided with a cover hole to avoid the burner head so that the top of the burner head extends out of the pot rack cover.

[0010] Optionally, the pot rack cover is fitted with the burner head with a gap, so that liquid on the pot rack cover flows into the bottom shell through the gap between the pot rack cover and the burner head.

[0011] Optionally, the peripheral wall of the cover hole is inclined downward toward the burner head, so that the liquid on the pot rack cover flows quickly into the bottom shell through the gap between the pot rack cover and the burner head.

[0012] Optionally, the sides of the pot cover adjacent to the plug-in boss extend to the outside of the bottom shell to facilitate the user's handling of the combustion module and to partially cover the bottom shell.

[0013] Optionally, the pot cover extends from the side away from the plug-in boss to the outside of the bottom shell to cover the bottom shell.

[0014] Optionally, the peripheral wall of the bottom shell slopes outward from bottom to top to facilitate the user's handling of the combustion module.

[0015] Optionally, an anti-slip pad is provided on the bottom side of the end of the bottom shell away from the insertion boss, so that the combustion module abuts against the base through the anti-slip pad.

[0016] Optionally, the combustion module further includes at least one burner cap installed on the burner head, the number of burner caps being the same as the number of air intake pipes, and corresponding one-to-one.

[0017] Optionally, the combustion module further includes an ignition needle mounted on the burner head, and the plug-in protrusion is provided with a contact terminal that is electrically connected to the ignition needle.

[0018] In a second aspect, this utility model provides a gas stove, comprising:

[0019] The base includes a panel, a mounting base located on the top side of the panel, and a nozzle with an air outlet located within the mounting base, the nozzle being hidden by the mounting base; at least one side of the mounting base in the horizontal direction is provided with a insertion hole aligned with the air outlet of the nozzle.

[0020] The combustion module described in any one of the first aspects, wherein the insertion boss of the combustion module is detachably inserted into the insertion hole.

[0021] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by providing a plug-in boss on one side of the bottom shell of the combustion module in the horizontal direction, the bottom shell is plugged into the base of the gas stove using the plug-in boss. This allows the combustion module of this utility model to be independently produced, manufactured, and sold, ensuring its compatibility with the base. Furthermore, it allows users to select a suitable new combustion module to replace the original combustion module on the gas stove according to their actual needs. Therefore, this utility model allows users to replace only the combustion module of the gas stove, reducing the cost for users when upgrading their gas stove.

[0022] Furthermore, by fitting the pot rack lid with a gap between it and the burner head, the liquid on the pot rack lid flows into the bottom shell through the gap between the pot rack lid and the burner head, allowing the bottom shell to act as a liquid collection tray for the combustion module to collect the liquid; this prevents the liquid from overflowing from the pot from flowing everywhere, thus improving the user experience.

[0023] Furthermore, by setting an anti-slip pad on the bottom side of the bottom shell away from the insertion boss, the combustion module abuts against the base through the anti-slip pad, effectively preventing the combustion module from sliding relative to the base and ensuring the stability of the gas stove during use.

[0044] like Figures 1 to 3 As shown, in some embodiments of this utility model, the gas stove 001 includes a base 100 and a combustion module 200. The combustion module 200 is detachably mounted on the base 100, allowing the user to easily remove the combustion module 200 from the base 100 for cleaning. Furthermore, the detachable combustion module 200 allows the user to replace only the combustion module 200 of the gas stove 001, significantly reducing the cost of replacing the gas stove 001, especially when the combustion module 200 is damaged or needs replacement.

[0045] It should be noted that, although Figures 1 to 3 The diagram shows two combustion modules 200, but the gas stove 001 of this invention is not limited to two. Those skilled in the art can adjust the number of combustion modules 200 on the gas stove 001 according to actual needs. For example, the number of combustion modules 200 can be set to one, three, four, etc.

[0046] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the base 100 includes a housing 110, a panel 120, and a fixing seat 130. The panel 120 is mounted on the top of the housing 110 and is fixedly connected to the housing 110; this fixed connection can be a snap-fit, screw connection, adhesive connection, etc. The fixing seat 130 is mounted on the panel 120 and is located in the middle of the left-right direction of the base 100. Simultaneously, a combustion module 200 is respectively provided on the left and right sides of the fixing seat 130, so that the gas stove 001 is symmetrical from left to right and more aesthetically pleasing.

[0047] Continue reading Figure 3 and Figure 4In some embodiments of this utility model, the left and right sides of the fixing base 130 are respectively provided with insertion holes 1301, so that the fixing base 130 can be inserted into the two combustion modules 200 through the two insertion holes 1301 respectively.

[0048] Of course, in other embodiments of this utility model, those skilled in the art can also, as needed, provide a plug hole 1301 aligned with the air outlet of the nozzle 102 on at least one side of the fixing base 130 in the horizontal direction, depending on the number of combustion modules 200. For example, when there is only one combustion module 200, a plug hole 1301 can be provided only on the front, rear, left, or right side of the fixing base 130.

[0049] like Figure 4 As shown, in some embodiments of this utility model, the fixing base 130 includes a fixing shell 131 fixedly connected to the panel 120 and a top cover 132 disposed at the top of the fixing shell 131.

[0050] like Figures 4 to 6 As shown, in some embodiments of this utility model, the left and right sides of the fixing shell 131 are respectively provided with insertion holes 1301, so that the fixing shell 131 can be inserted into the two combustion modules 200 through the two insertion holes 1301 respectively.

[0051] Of course, in other embodiments of this utility model, those skilled in the art can also, as needed, provide a plug hole 1301 aligned with the air outlet of the nozzle 102 on at least one side of the fixing shell 131 in the horizontal direction, depending on the number of combustion modules 200. For example, when there is only one combustion module 200, a plug hole 1301 can be provided only on the front, rear, left, or right side of the fixing shell 131.

[0052] like Figure 5 As shown, in some embodiments of this utility model, an annular post 1311 surrounding the insertion hole 1301 is provided on the inner side of the fixing shell 131. The annular post 1311 constitutes part of the peripheral wall of the insertion hole 1301 to increase the contact area between the insertion hole 1301 and the insertion boss 211, thereby improving the connection strength between the combustion module 200 and the fixing shell 131.

[0053] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the front sidewall of the fixing shell 131 is inclined forward from bottom to top, and the rear sidewall of the fixing shell 131 is inclined backward from bottom to top, so as to avoid liquids (such as soup, water, etc.) flowing downward along the front and rear sidewalls of the fixing shell 131 as much as possible.

[0054] To achieve the above objective, the angle between the front and rear sidewalls of the fixed shell 131 and the panel 120 is less than or equal to 75°, specifically 75°, 70°, 60°, 45°, etc.

[0055] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the front end of the top cover 132 extends to the front side of the fixing shell 131, and the rear end of the top cover 132 extends to the rear side of the fixing shell 131, so as to avoid liquids (such as soup, water, etc.) flowing onto the front and rear side walls of the fixing shell 131 as much as possible. At the same time, it can also cover the front and rear side walls of the fixing shell 131, improving the aesthetics of the gas stove 001.

[0056] Furthermore, in some embodiments of this utility model, the top cover 132 may be a component made of a semi-transparent material (such as glass, acrylic sheet, PVC sheet, etc.) to facilitate the user's observation of the connection between the combustion module 200 and the insertion hole 1301.

[0057] like Figure 4 As shown, in some embodiments of this utility model, the base 100 may further include a partition 140 disposed between the panel 120 and the fixing shell 131, the partition 140 being fixedly connected to the panel 120, and the fixing shell 131 being fixedly connected to the partition 140.

[0058] Furthermore, the panel 120 and the fixed shell 131 can be fixedly connected to the partition 140 in any feasible way, such as bonding, snap-fitting, screw connection, riveting, etc.

[0059] like Figure 7 As shown, in some embodiments of this utility model, the base 100 further includes a control knob 101, a nozzle 102, a first contact terminal 103, a diversion component 104, a control valve 105, an air supply pipe 106, and a sensor 107.

[0060] The control knob 101 is connected to the control valve 105, allowing the user to control the opening of the control valve 105 by rotating the control knob 101. The nozzle 102 supplies gas to the combustion module 200, the first contact terminal 103 supplies electrical energy to the combustion module 200 and / or transmits electrical signals, and the flow divider 104 receives external gas and distributes it to the control valve 105. The control valve 105 controls whether the nozzle 102 supplies gas to the combustion module 200. The flow divider 104, control valve 105, and nozzle 102 are sequentially fluidly connected via a gas supply pipe 106. The sensor 107 detects whether the combustion module 200 has been detached from the base 100. When the sensor 107 detects that the combustion module 200 has separated from the mounting base 130, the gas stove 001 controls the control valve 105 to close, preventing gas leakage.

[0061] Furthermore, in other embodiments of this utility model, those skilled in the art can omit at least one of the control knob 101, nozzle 102, first contact terminal 103, flow divider 104, control valve 105, gas pipe 106, and sensor 107 as needed. For example, the first contact terminal 103 can be omitted, allowing the user to ignite the combustion module 200 using a separate lighter, match, or electronic igniter. Another example is the omission of the flow divider 104, providing the gas stove 001 with only one control valve 105, one nozzle 102, and one combustion module 200. Yet another example is the omission of the sensor 107.

[0062] like Figures 1 to 4 As shown, in some embodiments of this utility model, the gas stove 001 includes two control knobs 101, each control knob 101 being located on the top side of the panel 120 and corresponding to a combustion module 200. Furthermore, the control knobs 101 are located on the front side of the combustion module 200 and are positioned in the left-right direction at the end of their corresponding combustion module 200 near the mounting base 130, thereby enhancing the aesthetics of the gas stove 001.

[0063] like Figure 4 As shown, in some embodiments of this utility model, the nozzle 102 extends from the bottom side of the panel 120 into the fixing housing 131. Furthermore, the bottom wall of the fixing housing 131 is provided with a clearance hole 1312 for avoiding the nozzle 102, so as to ensure that the air outlet of the nozzle 102 is located inside the fixing housing 131.

[0064] from Figure 4 and Figure 7 As can be seen from this, in some embodiments of this utility model, the first contact terminal 103 is also located inside the fixed shell 131, so as to cover the nozzle 102 and the first contact terminal 103 through the fixed shell 131 and the top cover 132, thereby improving the aesthetics of the gas stove 001.

[0065] Furthermore, although not shown in the figure, in some embodiments of this utility model, the air outlet of the nozzle 102 and the first contact terminal 103 are aligned with the insertion hole 1301 so that when the combustion module 200 is inserted into the insertion hole 1301, the air outlet of the nozzle 102 and the first contact terminal 103 are respectively connected to the corresponding components on the combustion module 200.

[0066] Continue reading Figure 4 and Figure 7 In some embodiments of this utility model, the base 100 also includes a fixing member (not marked in the figure) provided with a first contact terminal 103. The fixing member is cubic in shape and penetrates both the panel 120 and the fixing shell 131 to facilitate wiring.

[0067] Furthermore, in some embodiments of this utility model, the nozzle 102 can be fixed to the base shell 210 by means of pipes and pipe fittings made of rigid materials, or it can be fixed to the fixing shell 131 by means of plug-in, snap-fit, threaded connection, etc. The fixing member with the first contact terminal 103 can be fixed to the base shell 210 or the fixing shell 131 by means of screw connection, snap-fit, etc.

[0068] In this invention, the sensor 107 can be any feasible detection component, such as an infrared sensor, a micro switch, a reed switch, a Hall sensor, etc.

[0069] like Figure 7 As shown, in some embodiments of this utility model, the base 100 further includes a power supply module 150 disposed in the housing 110. The power supply module 150 is used to provide electrical energy for the use of the gas stove 001 and is electrically connected to the first contact terminal 103.

[0070] like Figures 1 to 3 As shown, in some embodiments of this utility model, a plug-in boss 211 is provided on one side of the combustion module 200 in the horizontal direction. Specifically, the plug-in boss 211 is provided on the side of the combustion module 200 near the fixing base 130, so that the combustion module 200 can be detachably plugged into the plug-in hole 1301 through the plug-in boss 211.

[0071] like Figures 8 to 10 As shown, in some embodiments of this utility model, the combustion module 200 includes a bottom shell 210, a second contact terminal 212, a magnet 213, a burner head 221, an ignition needle 222, a thermocouple 223, a flame cap 230, an air inlet pipe 240, a pot rack cover 250, and an anti-slip pad 260.

[0072] Continue reading Figures 8 to 10 The bottom shell 210 has a aforementioned insertion boss 211 on one side in the horizontal direction, which allows the bottom shell 210 to be inserted into the base 100 of the gas stove 001. Furthermore, the insertion boss 211 has a contact terminal that is electrically connected to the ignition needle 222; this contact terminal is the aforementioned second contact terminal 212. When the insertion boss 211 inserts the bottom shell 210 into the base 100 of the gas stove 001, the second contact terminal 212 abuts against the first contact terminal 103 to achieve electrical connection between the combustion module 200 and the base 100.

[0073] like Figure 9 As shown, the magnet 213 is embedded in the insertion boss 211 so that when the insertion boss 211 inserts the bottom shell 210 into the base 100 of the gas stove 001, the magnet 213 is attracted to the fixed shell 131.

[0074] To achieve the above objectives, the fixing shell 131 is provided with a structure or component that can be attracted by the magnet 213. For example, the fixing shell 131 is also provided with a magnet 213, or the fixing shell 131 is provided with an iron sheet, or the fixing shell 131 is a component made of iron.

[0075] In addition, at least one of the mounting base 130 and the combustion module 200 is provided with a magnet 213 so that the mounting base 130 and the combustion module 200 are locked together by magnetic attraction. Those skilled in the art may also, as needed, fix the magnet 213 on the mounting shell 131 and not provide the magnet 213 on the combustion module 200. For example, the insertion boss 211 can be made of iron.

[0076] like Figure 8 and Figure 9 As shown, in some embodiments of this utility model, the burner head 221 is disposed inside the bottom shell 210 and fixedly connected to the bottom shell 210, specifically by welding, screw connection, snap-fit, etc.

[0077] like Figure 8 As shown, in some embodiments of this utility model, the ignition needle 222 and the thermocouple 223 are respectively fixed to the burner head 221 and electrically connected to the second contact terminal 212. The ignition needle 222 is used to ignite the gas flowing from the burner head 221. The thermocouple 223 is used to detect the temperature of the burner head 221 or the burner cap 230, so that when the temperature of the burner head 221 or the burner cap 230 is detected to be low, the gas stove 001 closes the control valve 105 that has not been closed by the user. Since the functions and roles of the ignition needle 222 and the thermocouple 223 are common knowledge in the art and well known to those skilled in the art, they will not be described in detail here.

[0078] like Figure 8 As shown, in some embodiments of this utility model, the burner cap 230 is installed on the burner head 221 and there is at least one.

[0079] like Figure 8 and Figure 9 As shown, in some embodiments of this utility model, the air inlet end of the air inlet pipe 240 is fixedly connected to the insertion boss 211, so that the air inlet of the air inlet pipe 240 is formed on the insertion boss 211. Specifically, the insertion boss 211 is provided with a through hole (not marked in the figure), and the air inlet end of the air inlet pipe 240 passes through the through hole from the inside of the insertion boss 211. The air outlet end of the air inlet pipe 240 is connected to the burner head 221 to introduce gas into the burner head 221 through the air inlet pipe 240. The number of air inlet pipes 240, burner caps 230, and nozzles 102 are the same and correspond one-to-one.

[0080] like Figure 8 and Figure 9As shown, in some embodiments of this utility model, the pot rack cover 250 is installed on the bottom shell 210 to cover the internal space of the bottom shell 210. The pot rack cover 250 is provided with a cover hole 251 for avoiding the burner head 221 so that the top of the burner head 221 extends out of the pot rack cover 250.

[0081] Preferably, the pot cover 250 and the bottom shell 210 are detachably connected, such as by overlapping or snap-fitting, to facilitate the user's cleaning of the bottom shell 210 and its interior.

[0082] Furthermore, the pot rack cover 250 is fitted with the burner head 221 with a clearance so that the liquid on the pot rack cover 250 flows into the bottom shell 210 through the gap between the pot rack cover 250 and the burner head 221.

[0083] Those skilled in the art will understand that in some embodiments of this utility model, the bottom shell 210 can serve as a liquid collection tray for the combustion module 200 to collect liquid; this prevents the liquid overflowing from the pot on the pot rack lid 250 from flowing everywhere, thus improving the user experience.

[0084] Furthermore, the peripheral wall of the cover hole 251 is inclined downward toward the burner head 221 so that the liquid on the pot rack cover 250 flows quickly into the bottom shell 210 through the gap between the pot rack cover 250 and the burner head 221.

[0085] like Figure 10 As shown, in some embodiments of this utility model, the sides of the pot cover 250 and the plug-in boss 211 on both sides extend to the outside of the bottom shell 210 to facilitate the user to move the combustion module 200 and to cover part of the bottom shell 210.

[0086] Furthermore, the peripheral wall of the bottom shell 210 slopes outward from bottom to top to facilitate the user's handling of the combustion module 200.

[0087] Continue reading Figure 10 The pot cover 250 extends from the side away from the plug-in boss 211 to the outside of the bottom shell 210 to cover the bottom shell 210.

[0088] like Figure 9 and Figure 10 As shown, in some embodiments of this utility model, the anti-slip pad 260 is disposed on the bottom side of the bottom shell 210 away from the insertion boss 211, so that the combustion module 200 abuts against the base 100 through the anti-slip pad 260.

[0089] The anti-slip pad 260 and the bottom shell 210 can be fixed together by any feasible method such as snap-fit, screw connection, or adhesive. The anti-slip pad 260 can be a rubber pad, silicone pad, or other pad with high friction.

[0090] Those skilled in the art will understand that the contact between the anti-slip pad 260 and the panel 120, and the insertion between the insertion boss 211 and the insertion hole 1301, can jointly achieve the connection strength between the combustion module 200 and the base 100.

[0091] Furthermore, although not shown in the figure, in other embodiments of this utility model, those skilled in the art can, as needed, provide a suction cup made of elastic materials such as rubber, silicone, or latex on the bottom side of the bottom shell 210 so that the combustion module 200 can hold the panel 120 by the suction cup, thereby increasing the connection strength between the combustion module 200 and the base 100 and preventing the panel 120 from shaking.

[0092] Furthermore, the anti-slip mat 260 can be placed inside the suction cup to prevent the anti-slip mat 260 from being contaminated or soiled.

[0093] Furthermore, those skilled in the art can, as needed, provide a pressure relief pipe on the bottom side of the base 210, communicating with the suction cup and extending from the suction cup to the side of the base 210 not facing the fixing seat 130. This pressure relief pipe is equipped with a switch (e.g., a plug, threaded component, etc.). When it is necessary to remove the combustion module 200 from the base 100, the switch is turned on to allow outside air to enter the suction cup, preventing the combustion module 200 from being stuck to the panel 120 due to the negative pressure of the suction cup and thus unable to be removed.

[0094] In addition, in other embodiments of this utility model, those skilled in the art may omit at least one of the following components as needed: bottom shell 210, second contact terminal 212, magnet 213, stove head 221, ignition needle 222, thermocouple 223, flame cap 230, air inlet pipe 240, pot rack cover 250, and anti-slip pad 260, for example, omitting thermocouple 223 and / or magnet 213.

Specifically, it can be 1.3, 1.35, 1.4, 1.5, 1.7, 2, etc.

[0096] Furthermore, the ratio of the length L of the combustion module 200 in the left-right direction to the length b of the fixing base 130 in the left-right direction is selected from any value between 2.5 and 4. Specifically, it can be 2.5, 3, 3.4, 4, etc.

[0097] Furthermore, the width of the combustion module 200 in the front-to-back direction is equal to the width of the mounting base 130 in the front-to-back direction.

[0098] Furthermore, the projection of the combustion module 200 onto the base 100 is located inside the circumferential edge of the base 100. The horizontal distance between the circumferential edge of the combustion module 200 and the circumferential edge of the base 100 is selected from any value between 35mm and 180mm. Specifically, it can be 35mm, 40mm, 50mm, 80mm, 120mm, 180mm, etc.

[0099] from Figure 2 As can be seen, the distances between the left and right edges of the combustion module 200 and the left and right edges of the base 100, the distances between the front edge of the combustion module 200 and the front edge of the base 100, and the distances between the rear edge of the combustion module 200 and the rear edge of the base 100 can be different.

[0100] Based on the foregoing description, those skilled in the art will understand that by setting the combustion module 200 to be detachable relative to the base 100, this utility model not only facilitates the user's individual cleaning of the combustion module 200, but also reduces the cost for the user when replacing the gas stove 001, thereby improving the user experience.
