Description

Technical Field

[0001] This utility model relates to stoves, and more particularly to a dual-fan adjustable electric flame stove. Background Technology

[0002] Electric flame cooktops, as a new type of cooktop product, are gradually gaining market attention due to their environmentally friendly and safe features. These cooktops use high-voltage discharge to create plasma in the air, which then generates high-temperature heating to achieve cooking functions. This is an innovative cooktop solution that does not rely on gas.

[0003] In the current electric flame cooktop market, flame control is a crucial requirement for users. However, existing electric flame cooktops offer a relatively simple flame control method, primarily relying on a switch to alter the discharge current. Specifically, when users need to increase or decrease the flame, they can only change the current intensity by operating the switch. This change in current intensity directly affects the discharge intensity, thus adjusting the flame. This method has a significant limitation: it only adjusts all discharge electrodes of the cooktop as a whole. In other words, when the user adjusts the flame, the discharge intensity of all electrodes changes simultaneously, making independent control of the discharge intensity in different areas impossible. This overall adjustment characteristic makes electric flame cooktops lack flexibility in practical use. Utility Model Content

[0067] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a dual-fan adjustable electric flame stove.

[0068] Reference Figures 1 to 6 As shown, the dual-fan adjustable electric flame stove provided according to the embodiment of this utility model includes a stove base 10, a panel 20, an electric flame furnace 30, a first fan 40, and a second fan 41.

[0069] Specifically, the stove base 10 is used to support the entire structure of the electric flame stove and is made of metal materials, such as stainless steel, which has sufficient strength and stability.

[0070] A panel 20 is mounted on the stove base 10, and the panel 20 has a stove hole. The panel 20 is preferably made of tempered glass. The stove hole is used to install an electric flame stove 30, and the shape of the stove hole can be circular or other shapes, as long as it is compatible with the electric flame stove 30.

[0071] The electric flame furnace 30 includes a furnace head 301 and a furnace base 302. The furnace head 301 is mounted in the stove hole and is at least partially located above the panel 20. The furnace head 301 has a plurality of discharge electrodes 3013. A portion of the discharge electrodes 3013 form a first electrode group, and another portion of the discharge electrodes 3013 form a second electrode group. The discharge electrodes 3013 in the second electrode group are arranged around the first electrode group. Preferably, the first electrode group is located in the central region of the furnace head 301 and includes several evenly distributed discharge electrodes 3013, forming a central heating region. The discharge electrodes 3013 of the second electrode group are arranged concentrically around the periphery of the first electrode group, forming a peripheral heating region.

[0072] The furnace base 302 is located within the stove base 10 and connected to the bottom of the burner head 301. A first air chamber P101 and a second air chamber P102 are formed within the furnace base 302. The first air chamber P101 communicates with each discharge electrode 3013 in the first electrode group and is used to supply air to the discharge electrodes 3013 in the central heating area. The second air chamber P102 communicates with each discharge electrode 3013 in the second electrode group and is used to supply air to the discharge electrodes 3013 in the peripheral heating area.

[0073] It is understood that the discharge electrode 3013 typically includes a positive electrode 3013b and a negative electrode 3013a. The negative electrode 3013a is typically a sleeve-shaped structure, and the positive electrode 3013b is located inside the sleeve-shaped structure. Since the sleeve-shaped structure is a hollow structure, it can communicate with the first air cavity P101 or the second air cavity P102, thereby allowing air to be supplied to the discharge electrode 3013.

[0074] The first fan 40 is connected to the first air cavity P101 and is used to supply air to the first air cavity P101. The second fan 41 is connected to the second air cavity P102 and is used to supply air to the second air cavity P102. Both the first fan 40 and the second fan 41 can have their speeds independently controlled, thereby achieving independent adjustment of the air volume supplied to the two areas. Preferably, both the first fan 40 and the second fan 41 are variable frequency speed control fans, whose speeds can be precisely adjusted by a controller, thereby achieving precise control of the air volume.

[0075] In practical use, users can adjust the speed of the first fan 40 and the second fan 41 separately according to their cooking needs, thereby achieving independent control of the heat in the inner and outer areas. For example, when stir-frying over high heat, the first fan 40 and the second fan 41 can be adjusted to high speed at the same time; when simmering over low heat, the first fan 40 and the second fan 41 can be adjusted to low speed at the same time; when different heat levels are required for different areas, the speed of the first fan 40 and the second fan 41 can be adjusted separately.

[0076] According to the dual-fan adjustable electric flame stove provided in this embodiment, the discharge electrode 3013 is divided into an inner first electrode group and an outer second electrode group, with a first air chamber P101 and a second air chamber P102 respectively. The first fan 40 and the second fan 41 supply air independently to the two air chambers, allowing independent control of the airflow in the inner and outer areas. This design not only overcomes the limitation of traditional electric flame stoves that can only be adjusted as a whole, but also allows for flexible adjustment of the heat intensity in the inner and outer areas according to actual cooking needs, achieving more precise heat control. Furthermore, since the second electrode group is arranged around the first electrode group, this concentric circle layout ensures uniform heating and provides a guarantee for zoned control, thereby improving the practicality and cooking effect of the electric flame stove.

[0077] Reference Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment of this utility model, the furnace base 302 includes an inner cylinder 3021 and an outer cylinder 3022. Both the inner cylinder 3021 and the outer cylinder 3022 are made of a high-temperature resistant metal material, such as stainless steel. The outer cylinder 3022 is sleeved outside the inner cylinder 3021, and the lower end of the outer cylinder 3022 is connected and sealed to the lower end of the inner cylinder 3021. Preferably, the outer cylinder 3022 and the inner cylinder 3021 are an integral structure. The internal space of the inner cylinder 3021 forms the first air chamber P101, and the annular space between the inner cylinder 3021 and the outer cylinder 3022 forms the second air chamber P102.

[0078] The upper ends of both the outer cylinder 3022 and the inner cylinder 3021 are open and fit against the bottom surface of the burner head 301. Each discharge electrode 3013 in the first electrode group is connected to the internal space of the inner cylinder 3021, and each discharge electrode 3013 in the second electrode group is connected to the annular space.

[0079] In actual use, the air supplied by the first fan 40 enters the first air chamber P101 inside the inner cylinder 3021, and then flows out through the discharge electrodes 3013 of the first electrode group. The air supplied by the second fan 41 enters the annular second air chamber P102 between the outer cylinder 3022 and the inner cylinder 3021, and then flows out through the discharge electrodes 3013 of the second electrode group. This structural design ensures that the air supply to the inner and outer areas is completely independent.

[0080] In this embodiment, a coaxial sleeve structure is used as the furnace base 302. Its structure is simple and it is easy to form an independent first air cavity P101 and a second air cavity P102. At the same time, the coaxial design also ensures the uniformity of airflow distribution and provides a guarantee for the realization of zoned control.

[0081] Reference Figure 3 and Figure 6 As shown, in one embodiment of the present invention, the outer wall of the outer cylinder 3022 has a first interface 3023 for connecting to the second fan 41, and the outer wall of the inner cylinder 3021 has a second interface 3024. The second interface 3024 extends out from the outer wall of the outer cylinder 3022 for connecting to the first fan 40, and the second interface 3024 is sealed to the outer wall of the outer cylinder 3022.

[0082] In this embodiment, to achieve a reliable connection between the first blower 40 and the second blower 41 and the furnace base 302, a first interface component 3023 and a second interface component 3024 are respectively provided on the outer cylinder 3022 and the inner cylinder 3021 of the furnace base 302. Specifically, the first interface component 3023 is provided on the outer wall of the outer cylinder 3022. The first interface component 3023 has a tubular structure, one end of which is fixedly connected to the wall of the outer cylinder 3022 and has a communication hole for communicating with the second air chamber P102. The other end is a flange structure for easy and reliable connection with the second blower 41. At the same time, the second interface component 3024 is provided on the outer wall of the inner cylinder 3021. The second interface component 3024 adopts a through-type structure design, that is, the second interface component 3024 passes through the outer wall of the outer cylinder 3022 and connects to the inner cylinder 3021. The second interface component 3024 also adopts a tubular structure, with its inner end connected to the inner cylinder 3021 to guide airflow into the first air chamber P101, and its outer end also adopts a flange structure for connection with the first fan 40. This through-type interface design not only solves the problem of the arrangement of the air inlet channel of the inner cylinder 3021, but also provides a reliable structural foundation for the independent control of dual-zone firepower.

[0083] In practical applications, the air supplied by the first fan 40 enters the first air cavity P101 formed by the inner cylinder 3021 through the second interface 3024 and finally flows out from the first electrode group; the air supplied by the second fan 41 enters the annular second air cavity P102 between the outer cylinder 3022 and the inner cylinder 3021 through the first interface 3023 and flows out from the second electrode group. This design not only ensures unobstructed airflow but also facilitates the installation and maintenance of the fans, while avoiding mutual interference between airflow paths.

[0084] Reference Figure 6 As shown, in one embodiment of this utility model, the outer cylinder 3022 has a radially outward protruding retaining edge 3025 on its upper periphery. The bottom of the burner head 301 is provided with a plurality of latches 3012b, which are arranged at intervals along the circumference of the burner head 301. When the burner base 302 is assembled upward to the bottom of the burner head 301, the retaining edge 3025 is engaged above the latches 3012b, so that the burner base 302 and the burner head 301 are relatively fixed.

[0085] During actual assembly, when the furnace base 302 is pushed upwards into the bottom of the furnace head 301, the retaining edge on the outer cylinder 3022 will sequentially contact each of the retaining clips 3012b. Due to the elasticity of the retaining clips 3012b, under the upward pushing force, the hook portion on the retaining clip 3012b will temporarily deform outwards, allowing the retaining edge to pass through. After the retaining edge has completely passed the hook portion of the retaining clip 3012b, the hook portion returns to its original position under the elastic action, firmly locking and fixing the retaining edge, thus achieving a stable connection between the furnace base 302 and the furnace head 301. This retaining clip 3012b connection is simple and intuitive to install; assembly can be completed simply by pushing the furnace base 302 upwards. Furthermore, the connection reliability is high, with multiple retaining clips 3012b ensuring connection stability. In addition, it facilitates maintenance and disassembly; when maintenance or cleaning is required, the furnace base 302 can be removed simply by slightly deforming the retaining clips 3012b.

[0086] Reference Figures 2 to 6 As shown, in one embodiment of the present invention, the burner head 301 includes a cylindrical portion 3011 and a top plate 3012 disposed on the upper end of the cylindrical portion 3011. Preferably, the cylindrical portion 3011 is cylindrical in shape, and its outer diameter matches the stove hole on the panel 20, allowing an assembly gap of 0.5-1mm to ensure smooth insertion during installation.

[0087] The first electrode group and the second electrode group are disposed on the top plate 3012. The outer edge of the upper end of the cylindrical portion 3011 is provided with a shoulder 3014 that protrudes radially outward. Preferably, the shoulder 3014 is formed into an annular shape. The cylindrical portion 3011 is inserted into the stove hole, and the shoulder 3014 stops above the panel 20.

[0088] During actual installation, the cylindrical part 3011 of the burner head 301 is first inserted into the stove hole of the panel 20 from above. Because the outer diameter of the cylindrical part 3011 precisely matches the stove hole, coaxiality during installation is ensured. Once the cylindrical part 3011 is fully inserted, its upper shoulder 3014 naturally rests on the upper surface of the panel 20, serving both a limiting and supporting function.

[0089] In this embodiment, the burner head 301 with the above-described structure, combined with the limiting support function of the shoulder 3014, not only simplifies the installation process of the burner head 301, but also provides a stable structural support.

[0090] Preferably, the bottom of the top plate 3012 is also provided with an annular platform 3012a, and the upper end of the inner cylinder 3021 is inserted into the inner side of the annular platform 3012a. In this way, by utilizing the cooperation between the inner cylinder 3021 and the annular platform 3012a, the reliable and stable assembly of the structure is ensured, and the inner cylinder 3021 can isolate an independent first air cavity P101, which further improves the isolation between the first air cavity P101 and the second air cavity P102.

[0091] Reference Figure 1 As shown, in some embodiments of this utility model, a circuit board is provided inside the stove base 10, and a first adjustment switch 50 and a second adjustment switch 51 are provided on the panel 20. The first adjustment switch 50 is connected to the circuit board and is used to adjust the air volume of the first fan 40. The second adjustment switch 51 is connected to the circuit board and is used to adjust the air volume of the second fan 41.

[0092] When the user rotates the first adjustment switch 50 or the second adjustment switch 51, the switch transmits a position signal to the circuit board. The circuit board then adjusts the speed of the first fan 40 or the second fan 41 through a frequency converter control circuit, thereby regulating the airflow entering the first air chamber P101 or the second air chamber P102. This independent dual-fan control method allows the user to adjust the airflow of the inner and outer heating zones separately according to actual needs, achieving more precise firepower control, and is also easy to operate.

[0093] Reference Figure 6 As shown, in one embodiment of the present invention, the bottom of the burner head 301 is provided with a flow guiding structure. The flow guiding structure includes a downwardly protruding conical flow guiding platform 3012c. The circumferential surface of the conical flow guiding platform 3012c is provided with a plurality of first guide fins 3012d evenly distributed along the circumference. The extension direction of each first guide fin 3012d forms a preset angle with the radial direction of the first air cavity P101, so that the airflow entering the first air cavity P101 forms a rotating airflow.

[0094] In other words, when the airflow passes through these inclined first guide fins 3012d, it changes its direction of motion under the guidance of the first guide fins 3012d, obtaining a tangential velocity component, thereby forming a stable rotating airflow field within the first air cavity P101. The rotating motion increases the residence time of the airflow within the first air cavity P101, and the centrifugal force makes the airflow distribution more uniform, avoiding the formation of local airflow dead zones; in addition, the rotating airflow can also improve the stability of the flame and improve the combustion effect.

[0095] Reference Figure 6 As shown, in one embodiment of the present invention, the outer circumferential surface of the inner cylinder 3021 is provided with a plurality of second guide fins 3021a evenly distributed in the circumferential direction, and a gap is left between each second guide fin 3021a and the inner wall of the outer cylinder 3022, and the second guide fins 3021a extend radially along the inner cylinder 3021.

[0096] In this embodiment, the second guide fin 3021a can effectively guide the airflow in the second air cavity P102 to disperse it to the position of each discharge electrode 3013. On the one hand, it avoids the airflow from becoming turbulent in the annular space, so that the airflow can flow into each discharge electrode 3013 evenly, thereby improving the stability and uniformity of the flame in the same area.

[0097] In some embodiments of this utility model, both the first air cavity P101 and the second air cavity P102 are provided with anti-backfire mesh (not shown). The anti-backfire mesh is made of metal wire mesh, and the mesh size of the metal wire mesh is smaller than the quenching distance of the flame propagation.

[0098] When a flame passes through a channel shorter than its quenching distance, it will be unable to continue spreading due to rapid heat dissipation. Therefore, even if backfire occurs under abnormal conditions, the flame will be quickly extinguished when passing through the anti-backfire net, thus preventing the flame from spreading into the air cavity and effectively protecting the safety of important components such as the first fan 40 and the second fan 41, thereby improving safety.
