Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to an electric flame stove with a dry-burning alarm function. Background Technology

[0002] An electric flame stove, as the name suggests, is a type of open-flame stove that does not use chemical fuels; it can also be described as a device that ignites air. At first glance, an electric flame stove looks just like a gas stove commonly used in households, both using flames to heat food. The difference is that a gas stove requires natural gas or liquefied petroleum gas (LPG). Without these gases, a gas stove cannot function. Furthermore, the gas used in gas stoves is a hazardous material; leaks can easily lead to explosions, which can be extremely dangerous.

[0003] Therefore, electric flame stoves have emerged. They are highly safe to use, and users do not need to worry about the risks of gas explosions. However, since they have only been developed in recent years, their production time is short, and their cost is much higher than that of gas stoves. Therefore, their popularity is still not very high. But with the development of technology, their cost will inevitably decrease, making them widely used in the future.

[0004] Most electric stoves on the market do not have a dry-burn alarm function. This means that if the cook takes the cookware off the stove to wash it without turning it off, or if the cook takes the cookware off the stove to wash it and then leaves in a hurry, the electric flame produced by the stove will remain outside the burner for an extended period, causing dry burning and posing a fire hazard. There are many cases of fires caused by dry burning of electric stoves in daily life, which can result in personal injury and / or property damage, and this should definitely be taken seriously.

[0005] In response, the inventor of this patent, drawing on work experience, deeply considered the problems encountered in his work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this utility model is to provide an electric flame stove with a dry-burning alarm function.

[0007] To achieve one of the above objectives, according to an embodiment of the present utility model, an electric flame stove with a dry-burning alarm function includes a stove body, an electric flame stove main control device is provided inside the stove body, an installation port is opened on the upper surface of the stove body, and an electric flame burner head is installed in the installation port. It also includes an open flame detection column and a pot ring for supporting cookware.

[0008] The pot ring is formed into a hollow cylindrical structure and is placed on the electric flame burner head to enclose the periphery of the electric flame burner head;

[0009] The open flame detection column is fixed on the upper surface of the stove body and located at the rear of the electric flame burner head. It is used to detect open flames emanating from the upper part of the pot ring and to output an alarm when an open flame is detected emanating from the upper part of the pot ring.

[0010] In addition, the electric flame stove with dry-burning alarm function according to the above embodiments of this utility model may also have the following additional technical features:

[0011] According to one embodiment of the present invention, a viewing window is provided on the upper part of the front end face of the open flame detection column, and a visible light flame detector connected to the main control device of the electric flame stove is embedded in the viewing window. The open flame detection column or the stove body is also provided with an open flame alarm connected to the main control device of the electric flame stove.

[0012] The visible light fire detector is located at a height slightly higher than the upper edge of the pot ring;

[0013] When the visible flame detector detects an electric flame emerging from the top of the pot ring, it transmits the detection signal to the main control device of the electric flame stove, and the main control device of the electric flame stove controls the open flame alarm to output an alarm.

[0014] According to one embodiment of the present invention, the open flame alarm is a sound alarm and / or a sound and light alarm.

[0015] According to one embodiment of the present invention, the outer diameter of the pot ring gradually decreases from bottom to top, and a flow groove penetrating into the interior is provided on the upper front part of the outer wall of the pot ring. The upper edge of the pot ring is flat and without sharp edges to fit and conform to the bottom surface of the pot.

[0016] According to one embodiment of the present invention, a plurality of electric flame nozzles are evenly arranged upward on the middle of the upper surface of the electric flame burner head, and a limiting groove is formed by the downward indentation of the upper surface of the electric flame burner head near its outer edge; the bottom of the pot ring is interference-fitted into the limiting groove.

[0017] According to one embodiment of the present invention, it further includes a power connector, a power module, and a power switch for controlling the power supply module to be powered on or off.

[0018] The power module is located inside the stove body; the power switch is located on the upper surface of the stove body and is connected between the power plug and the power module; the power module is connected to the main control device of the electric flame stove.

[0019] According to one embodiment of the present invention, it further includes an electric flame generator disposed in the stove body and facing the mounting port, and the upper end face of the stove body is also provided with a switch knob for adjusting the size of the electric flame generated by the electric flame generator.

[0020] The switch knob is connected between the main control device of the electric flame stove and the electric flame generator.

[0021] According to one embodiment of the present invention, it further includes an exhaust fan and a ventilation fan disposed in the stove body;

[0022] Both the exhaust fan and the venting fan are connected to the main control device of the electric flame stove; the right end face of the stove body is provided with an air inlet and the left end face is provided with an air outlet; the exhaust fan is located in the air inlet to draw air into the stove body; the venting fan is located in the air outlet to exhaust air out of the stove body.

[0023] According to one embodiment of the present invention, the four corners of the bottom of the stove body are respectively provided with lifting pads, and the bottom surface of the stove body is provided with heat dissipation holes that connect to the interior.

[0024] The beneficial effects of this utility model are:

[0025] Firstly, in practical implementation, the electric flame stove with dry-burning alarm provided in this application allows for the direct placement of cookware onto the pot ring during use. The cookware is kept as stationary as possible during use, and the pot ring provides insulation, minimizing the risk of open flames (electric flames) escaping from the top of the pot ring, thus reducing the likelihood of fire hazards in the kitchen. When the user lifts the cookware to wash or replace it, the open flame detection column detects an open flame (electric flame) escaping from the top of the pot ring and triggers an alarm, prompting the user to quickly place the cookware back onto the pot ring. This effectively warns and reminds the user not to leave the cookware unattended or forget to return it to the pot ring, further optimizing the safety of the application and encouraging users to prevent fires, making the kitchen less prone to fire hazards.

[0026] Secondly, when the user places the cookware back onto the pot ring, the bottom of the pot and the pot ring isolate the cookware, or the application is turned off directly, making it difficult for open flame (electric flame) to emerge from the top of the pot ring. At this time, the open flame detection column cannot detect the open flame (electric flame), and it will not output an alarm. Therefore, the application can be considered safe to use.

[0027] Thirdly, by setting up the pot ring, it not only serves to support the cookware but also to block water and oil stains, effectively preventing external water and oil stains from splashing onto the surface of the electric flame burner through its upper and lower ends or its outer wall, thus making it dirty. This dual-purpose design results in good anti-pollution effect on the surface of the electric flame burner, greatly reducing the frequency of cleaning. As the outer diameter of the pot ring gradually decreases from bottom to top, it forms a hollow frustum-shaped structure, with a smaller opening at the top, creating a constricted opening. This makes it less likely for external water and oil stains to enter through the upper opening and contaminate the electric flame burner and other structural components, while also ensuring its stable placement.

[0028] Fourthly, by opening a flow groove in the upper front part of the outer wall of the pot ring, it is not only convenient for the air to flow inside and outside the pot ring, but also makes it easy for the user to observe the size of the electric flame coming out of the electric flame burner through the flow groove, so as to make visual adjustment of the size of the electric flame coming out of the electric flame burner according to actual needs.

[0029] Fifthly, since the flow channel is facing away from the visible light flame detector, open flames (electric flames) visible through the flow channel are not easily detected by the visible light flame detector, making this application still reliable in use. Furthermore, because the upper edge of the pot ring is flat and without sharp edges to fit snugly against the bottom surface of the pot, even when the pot is placed on the pot ring, its bottom surface will fit tightly against the upper edge of the pot ring, making it even less likely for open flames (electric flames) to leak out from the upper part of the pot ring, thus making this application safer and more reliable in use.

[0030] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0066] The electric flame stove 1000 with dry-burning alarm function according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0067] Reference Figures 1 to 5 As shown, the electric flame stove 1000 with dry burning alarm function provided according to the embodiment of the present utility model includes a stove body 10, an electric flame stove main control device 20 is provided inside the stove body 10, an installation port 101 is opened on the upper surface of the stove body 10, and an electric flame burner head 30 is installed in the installation port 101. The improvement of the present utility model is that the present application also includes an open flame detection column 40 and a pot ring 50 for supporting the pot.

[0068] The pot ring 50 is formed into a hollow cylindrical structure and is placed on the electric flame burner head 30 to surround the periphery of the electric flame burner head 30.

[0069] Furthermore, the open flame detection column 40 is fixedly mounted on the upper surface of the stove body 10 and located at the rear of the electric flame burner head 30. It is used to detect the open flame (electric flame) emanating from the upper part of the pot ring 50, and outputs an alarm when an open flame (electric flame) is detected emanating from the upper part of the pot ring 50. Conversely, no alarm is output when no open flame (electric flame) is detected emanating from the upper part of the pot ring 50.

[0070] Based on the above, it is clear that in specific implementation, this application is mainly used as an electric flame stove 1000 with a dry-burning alarm function.

[0071] Specifically, when using this application, the user places the cookware to be used on the pot ring 50 and activates this application. When the cookware is not lifted, the bottom of the pot and the pot ring 50 isolate the cookware, so that the open flame detection column 40 cannot detect the open flame (electric flame). At this time, it will not output an alarm, and the use of this application can be assumed to be safe.

[0072] When the user lifts the pot, an open flame (electric flame) will emerge from the top of the pot ring 50. At this time, the open flame detection column 40 can detect the open flame (electric flame) and output an alarm to remind the user to place the pot to be used on the pot ring 50 as soon as possible. In this way, the user can be better reminded to pay attention to safety and avoid the open flame (electric flame) from catching fire in the kitchen as much as possible.

[0073] Clearly, the use of this application will have the following technical effects:

[0074] On the one hand, when using this application, the cookware is placed directly on the pot ring 50 for use, and is used without lifting it as much as possible. In addition, the pot ring 50 isolates the cookware, making it difficult for open flames (electric flames) to emerge from the top of the pot ring 50, thus reducing the risk of fire in the kitchen.

[0075] On the other hand, when the user lifts the pot to wash or replace it, the open flame detection column 40 can detect an open flame (electric flame) emanating from the top of the pot ring 50 and output an alarm to remind the user to quickly place the pot back on the pot ring 50. This effectively warns and reminds the user not to move the pot away for an extended period or forget to put it back on the pot ring 50. This further optimizes the safety of the application and encourages users to prevent fires, making the kitchen less prone to fire hazards.

[0076] Furthermore, when the user places the cookware back onto the pot ring 50, the bottom of the pot and the pot ring 50 isolate the cookware, or the application is turned off directly, making it difficult for open flame (electric flame) to emerge from the top of the pot ring 50. At this time, the open flame detection column 40 cannot detect the open flame (electric flame), and it will not output an alarm, so the application can be considered safe to use.

[0077] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0078] Furthermore, in specific implementation, in accordance with... Figure 1 and Figure 4 As shown, according to one embodiment of the present utility model, a viewing window is provided on the upper part of the front end face of the open flame detection column 40, and a visible light flame detector 401 connected to the main control device 20 of the electric flame stove is embedded in the viewing window. The open flame detection column 40 or the stove body 10 is also provided with an open flame alarm 402 connected to the main control device 20 of the electric flame stove.

[0079] The visible light fire detector 401 is located at a height slightly higher than the height of the upper edge of the pot ring 50;

[0080] When the visible light flame detector 401 detects an electric flame emerging from the top of the pot ring 50, it transmits the detection signal to the electric flame stove main control device 20, and the electric flame stove main control device 20 controls the open flame alarm 402 to output an alarm.

[0081] Therefore, it is clear that in the actual application of this application, the visible light flame detector 401 should be positioned at a height slightly higher than the height of the upper edge of the pot ring 50. This ensures that once an open flame (electric flame) emerges from the upper part of the pot ring 50, it can be detected by the visible light flame detector 401, and the detection signal will be transmitted to the electric flame stove main control device 20. When the electric flame stove main control device 20 receives the detection signal, it will control the open flame alarm 402 to output an alarm. In this way, this application is very reliable in actual use.

[0082] Preferably, in this technical solution, according to an embodiment of the present invention, the open flame alarm 402 is a sound alarm and / or a sound and light alarm, so as to have at least a sound alarm prompt, making the alarm very conspicuous. For users with hearing problems, the open flame alarm 402 is preferably a sound and light alarm, so that the sound alarm and light alarm are output simultaneously. In this case, the present application is also suitable for users with hearing problems in the hall, so that the present application has strong adaptability.

[0083] Furthermore, in specific implementation, in accordance with... Figure 1 , Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, the outer diameter of the pot ring 50 gradually decreases from bottom to top, and the upper front part of the outer wall of the pot ring 50 is provided with a flow groove 501 that extends into its interior. The upper edge of the pot ring 50 is flat and without sharp edges to fit and conform to the bottom surface of the pot.

[0084] In this regard, it is clear that:

[0085] On the one hand, by setting the pot ring 50, it is not only used to support the pot, but also to block water and oil stains, so as to better prevent external water and oil stains from splashing onto the surface of the electric flame burner 30 through its upper and lower ends or its outer wall and dirtying it. This makes it a dual-purpose unit, so that the surface of the electric flame burner 30 has a good anti-pollution effect and can greatly reduce the number of times the surface of the electric flame burner 30 needs to be cleaned.

[0086] On the other hand, when the outer diameter of the pot ring 50 gradually decreases from bottom to top, the pot ring 50 is formed into a hollow frustum-shaped structure, so that its upper opening is smaller and forms a constricted opening, making it less likely for external water and oil stains to enter through its upper opening and contaminate the electric flame burner head 30 and other structural components, and making it stable to place.

[0087] Furthermore, by opening a flow groove 501 that extends into the upper front part of the outer wall of the pot ring 50, it is not only convenient for the air to flow inside and outside the pot ring 50, but also makes it convenient for the user to observe the size of the electric flame coming out of the electric flame burner head 30 through the flow groove 501, so as to make visual adjustment of the size of the electric flame coming out of the electric flame burner head 30 according to actual needs.

[0088] Meanwhile, since the flow channel 501 is facing away from the visible light flame detector 401, the open flame (electric flame) visible from the flow channel 501 is not easily detected by the visible light flame detector 401, making the application still reliable in use. Furthermore, since the upper edge of the pot ring 50 is flat and without sharp edges to fit the bottom surface of the pot, even when the pot is placed on the pot ring 50, its bottom surface will fit tightly against the upper edge of the pot ring 50, making it even less likely for an open flame (electric flame) to be exposed from the upper part of the pot ring 50, thus making the application safer and more reliable in use.

[0089] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0090] Furthermore, in this technical solution, compared with Figure 1 and Figure 4 As shown, according to one embodiment of the present invention, a plurality of electric flame nozzles 301 are evenly arranged upward on the middle of the upper end face of the electric flame burner head 30, and a ring of limiting groove 302 is formed by the downward indentation of the upper end face of the electric flame burner head 30 near its outer edge; the bottom of the pot ring 50 is interference-fitted into the limiting groove 302.

[0091] In this regard, it can be clearly seen that by setting multiple electric flame nozzles 301, the generated electric flames are evenly sprayed upwards through them. By setting a ring of limiting grooves 302, the bottom of the pot ring 50 can be firmly secured with an interference fit, making the pot ring 50 less prone to circumferential displacement.

[0092] Furthermore, in specific implementation, it is necessary to refer to... Figure 1 and Figure 5 As shown, according to one embodiment of the present invention, this application also includes a power connector 60, a power module 70, and a power switch 80 for controlling the power supply to and from the power module 70.

[0093] The power module 70 is located inside the stove body 10; the power switch 80 is located on the upper surface of the stove body 10 and is connected between the power plug 60 and the power module 70; the power module 70 is connected to the main control device 20 of the electric flame stove.

[0094] Therefore, by connecting the power plug 60 to an external power source and operating the power switch 80 to connect the power plug 60 and the power module 70, power can be supplied to this application. The power module 70 is preferably a high-power rechargeable power supply, so that this application also has its own power source. Even when there is no mains power, this application can still work, so that this application can be used without interruption, resulting in better overall reliability.

[0095] Furthermore, in specific implementation, we will continue to refer to... Figure 1 and Figure 5 As shown, according to one embodiment of the present invention, this application also includes an electric flame generator 90 disposed inside the stove body 10 and facing the mounting port 101, and the upper end face of the stove body 10 is also provided with a switch knob 100 for adjusting the size of the electric flame generated by the electric flame generator 90.

[0096] The switch knob 100 is connected between the main control device 20 of the electric flame stove and the electric flame generator 90.

[0097] Therefore, it is clear that if simply operating the power switch 80 does not ignite the device, the power module 70 is preferably a high-power rechargeable power supply and is in a powered state. Alternatively, the power switch 80 can be operated to connect the power plug 60 to the power module 70, and then the switch knob 100 can be operated to control the electric flame stove main control device 20 to drive the electric flame generator 90 to work, so that electric flames are evenly sprayed upwards from the multiple electric flame nozzles 301 of the power burner head. In this way, the device can be used easily.

[0098] Based on this, in specific implementation, refer to Figures 1 to 5 As shown, according to one embodiment of the present invention, this application also includes an exhaust fan 110 and an exhaust fan 120 disposed within the stove body 10;

[0099] The exhaust fan 110 and the venting fan 120 are both connected to the main control device 20 of the electric flame stove; the stove body 10 has an air inlet 102 on the right end and an air outlet 103 on the left end; the exhaust fan 110 is located in the air inlet 102 to exhaust air into the stove body 10; the venting fan 120 is located in the air outlet 103 to exhaust air out of the stove body 10; the power switch 80 also controls the switching on and off of the exhaust fan 110 and the venting fan 120.

[0100] Therefore, by setting up the exhaust fan 110, the exhaust fan 120, the air inlet 102 and the exhaust outlet 103, the air flow inside the stove body 10 of this application is greatly accelerated, so that the electrical components such as the electric flame stove main control device 20 set inside the stove body 10 of this application have good heat dissipation effect and long service life.

[0101] Furthermore, preferably, in this technical solution, compared with Figure 3 As shown, according to one embodiment of the present invention, the stove body 10 is provided with lifting foot pads 104 at the four corners of its bottom, and the bottom surface of the stove body 10 is provided with heat dissipation holes 105 that connect to its interior.

[0102] Thus, by setting the heat dissipation hole 105 and the lifting foot pad 104 to raise the stove body 10, it is possible to further facilitate heat dissipation inside the stove body 10 of this application, so that the heat generated inside the stove body 10 can be discharged not only from the exhaust port 103 set on the left end face of the stove body 10, but also from the heat dissipation hole 105 opened at the bottom of the stove body 10, so that the heat dissipation effect of the electric flame stove main control device 20 and other electrical components set inside the stove body 10 of this application is better.

[0103] Meanwhile, the multiple lifting pads 104 provided can effectively prevent water stains or other substances that may exist on the stove or other countertops from flowing into the stove body 10 when the stove body 10 is placed on it, thus making the stove body 10 more moisture-proof.

[0104] It should be added that, in specific implementation, the upper outlets of the multiple electric flame nozzles 301 are all formed as constricted openings to make them smaller. In this way, the electric flames ejected through their upper outlets will be more slender, so that they can better contact the bottom of the pot mounted on the pot ring 50 to heat it. This makes the overall flame output effect better when the application is used, and thus the overall cooking effect can be better.

[0105] Furthermore, in specific implementation, in the field of open flame detection and alarm, the circuit design for sequentially connecting the visible flame detector 401, the main controller, and the open flame alarm 402 to detect open flames using the visible flame detector 401 and control the open flame alarm 402 to output an alarm using the main controller is a mature existing technology. For example, the invention patent "An Independent Flame Detection Alarm" disclosed in patent number "202020183821.4" and the utility model patent "Energy Storage Prefabricated Cabin with Automatic Alarm Function for Open Flame Detection" disclosed in patent number "202121380173.2" are simply applied to electric flame stoves to achieve open flame detection and alarm by setting an open flame detection column 40 on the electric flame stove.

[0106] Therefore, it is clear that this application mainly improves the physical structure of the electric flame stove. As for the circuit principle itself, there is basically no need to improve it, and existing technology can be directly adopted. Therefore, the specific circuit details between the various circuit modules set in this application will not be described in detail in this patent application document.

[0107] Other embodiments are not described here.

[0108] In summary, the electric flame stove 1000 with dry-burn alarm function provided in this application, in practical implementation, allows the cookware to be placed directly on the pot ring 50 for use, minimizing the need to lift it during use. Furthermore, the pot ring 50 provides insulation, reducing the likelihood of open flames (electric flames) emanating from its upper part, thus minimizing fire safety hazards in the kitchen. When the user lifts the cookware to wash or replace it, the open flame detection column 40 detects an open flame (electric flame) emanating from the upper part of the pot ring 50 and outputs an alarm, prompting the user to quickly place the cookware back on the pot ring 50. This effectively warns and reminds the user not to move the cookware away for extended periods or forget to return it to the pot ring 50, thereby further optimizing the safety of this application and encouraging users to prevent fires, making the kitchen less prone to fire hazards.

[0109] Furthermore, when the user places the cookware back onto the pot ring 50, the pot bottom and the pot ring 50 isolate the cookware, or the application is turned off directly, making it difficult for open flame (electric flame) to emerge from the top of the pot ring 50. At this time, the open flame detection column 40 cannot detect the open flame (electric flame), and it will not output an alarm, so the application can be considered safe to use.

[0110] Furthermore, by providing the pot ring 50, it not only serves to support the cookware but also to deflect water and oil stains, effectively preventing external water and oil stains from splashing onto the surface of the electric flame burner head 30 through its upper and lower ends or its outer wall, thus making it dual-purpose. This results in excellent anti-contamination performance of the electric flame burner head 30 surface, significantly reducing the frequency of cleaning. As the outer diameter of the pot ring 50 gradually decreases from bottom to top, it forms a hollow frustum-shaped structure with a smaller opening at the top, creating a constricted opening. This makes it less likely for external water and oil stains to enter through the upper opening and contaminate the electric flame burner head 30 and other structural components, while also ensuring its stable placement.

[0111] Furthermore, by opening a flow groove 501 that extends into the upper front part of the outer wall of the pot ring 50, it is not only convenient for the air to flow inside and outside the pot ring 50, but also makes it easy for the user to observe the size of the electric flame coming out of the electric flame burner head 30 through the flow groove 501, so as to make visual adjustment of the size of the electric flame coming out of the electric flame burner head 30 according to actual needs.

[0112] Meanwhile, since the flow channel 501 is facing away from the visible light flame detector 401, the open flame (electric flame) visible from the flow channel 501 is not easily detected by the visible light flame detector 401, making the application still reliable in use. Furthermore, since the upper edge of the pot ring 50 is flat and without sharp edges to fit the bottom surface of the pot, even when the pot is placed on the pot ring 50, its bottom surface will fit tightly against the upper edge of the pot ring 50, making it even less likely for an open flame (electric flame) to be exposed from the upper part of the pot ring 50, thus making the application safer and more reliable in use.

[0113] Furthermore, the electric flame stove 1000 with dry-burning alarm function provided in this application is indeed highly practical and has excellent performance, which makes this application inherently valuable for market promotion and will certainly be very popular and effectively popularized.
