Technical Field
[0001] This utility model belongs to the field of kitchen equipment technology, specifically a floor stove with upper and lower partition temperature control and fume extraction. Background Technology
[0002] In modern kitchens, the traditional floor stove is a common cooking tool, and its performance and user experience significantly impact the user experience. Currently, most floor stoves on the market use a single temperature control design, making it difficult to achieve independent temperature control for the upper and lower sections during cooking. This results in uneven heat distribution and affects cooking results. Furthermore, traditional floor stoves have limitations in fume extraction, often failing to efficiently handle the fumes generated during cooking, easily leading to kitchen environmental pollution.
[0003] For example, some existing underfloor stoves improve fume extraction efficiency by adding exhaust ducts or fans, but these designs usually require a large installation space and may lead to inconvenience in cleaning and maintenance due to their complex structure. At the same time, due to the lack of effective guidance for the flow of fumes, some fumes may not be completely exhausted and remain in the kitchen, affecting air quality.
[0004] Therefore, we made improvements and proposed a floor stove with upper and lower zone temperature control and fume extraction. Utility Model Content
[0005] The purpose of this invention is to solve the problems of existing floor stoves that cannot achieve independent temperature control in the upper and lower sections and have low efficiency in smoke extraction during the cooking process.
[0006] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a dual-zone temperature-controlled fume extraction stove, comprising a stove body, a temperature control component, and a fume extraction component. The stove body is internally divided into an upper heating chamber and a lower heating chamber by a partition plate. The temperature control component is connected to both the upper and lower heating chambers for independent temperature control of the two chambers. The fume extraction component is located at the top of the stove body and communicates with the upper heating chamber to guide the fumes out.
[0007] The temperature control assembly includes two independent heating units, namely a first heating unit and a second heating unit. The first heating unit is installed at the bottom of the upper heating chamber, and the second heating unit is installed at the bottom of the lower heating chamber. Each of the first and second heating units has an independent temperature control adjustment device, which is connected to an external power source via wires and allows temperature setting via a knob or touchscreen. A vent is provided in the center of the partition plate, and an adjustable baffle is installed inside the vent. The baffle is movably connected to the partition plate via a rotating shaft, used to adjust heat exchange between the upper and lower heating chambers.
[0008] The fume extraction assembly includes a fume collection hood and an exhaust duct. The fume collection hood is fixed to the top of the stove body and covers the opening area of the heating chamber. One end of the exhaust duct is connected to the fume collection hood, and the other end extends to the external exhaust system. A guide plate is provided on the inner side of the fume collection hood. The guide plate has an arc-shaped design, with its upper end inclined towards the exhaust duct to guide the fumes along a preset path. The surface of the guide plate has several evenly distributed guide grooves with a semi-circular cross-section to reduce the adhesion of fumes to the guide plate.
[0009] As a preferred technical solution of this application, the outer side of the stove body is provided with a heat insulation layer. The heat insulation layer is made of high-temperature resistant material and has a thickness of 10mm to 20mm, which is used to reduce the temperature of the stove body surface and prevent users from being burned. The outer surface of the heat insulation layer is provided with anti-slip texture, which is distributed in a grid pattern to enhance the friction during user operation.
[0010] As a preferred technical solution of this application, both the first heating unit and the second heating unit include a heating plate and a heating tube. The heating plate is fixed to the bottom of the heating cavity, and the heating tube is embedded inside the heating plate and fixed with bolts. The surface of the heating plate is provided with several evenly distributed protrusions, the height of which is 2mm to 5mm, to increase the heating area and improve the heat conduction efficiency.
[0011] As a preferred technical solution of this application, the top of the fume collection hood is equipped with a fan. The fan is fixed to the inside of the fume collection hood by a bracket, with its air inlet aligned with the end of the guide plate and its air outlet connected to the exhaust pipe. The fan blades are made of stainless steel and coated with an oil-resistant coating to reduce the accumulation of fumes on the blades.
[0012] As a preferred technical solution of this application, the exhaust duct is equipped with a filter screen inside. The filter screen is composed of multiple layers of metal wire mesh, each layer of metal wire mesh having a pore size of 0.5mm to 1mm, for intercepting particulate matter in the fumes. The filter screen has slots on both sides that engage with the inner wall of the exhaust duct for easy disassembly and cleaning.
[0013] As a preferred technical solution of this application, the adjustable baffle of the vent is provided with a handle, which is fixed to one end of the rotating shaft and extends to the outside of the stove body for manually adjusting the opening angle of the baffle. The edge of the baffle is provided with a sealing strip, which is made of silicone material to enhance the sealing between the baffle and the vent.
[0014] As a preferred technical solution of this application, the bottom of the stove body is provided with four support feet, which are located at the four corners of the stove body. The bottom of each support foot is provided with an anti-slip pad made of rubber material, which is used to enhance the stability of the stove body and prevent slippage.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: The cooktop is divided into an upper heating chamber and a lower heating chamber by a partition, each equipped with an independent heating unit and temperature control device, enabling independent temperature control for both chambers. Users can set the temperature of each chamber according to their cooking needs, ensuring even heat distribution and improving cooking results. Furthermore, by incorporating vents and adjustable baffles on the partition, users can adjust the heat exchange between the upper and lower chambers as needed, further optimizing temperature control performance.
[0016] By incorporating a fume collection hood, a baffle plate, and a fan, the system effectively guides and rapidly exhausts cooking fumes. The curved design of the baffle plate and the structure of the guide channel reduce the retention of fumes within the collection hood, while the efficient operation of the fan ensures that the fumes enter the exhaust duct along a pre-designed path. Furthermore, the filter screen inside the exhaust duct intercepts particulate matter in the fumes, preventing it from entering the external exhaust system and thus reducing environmental pollution.
[0017] By installing a heat insulation layer on the outside of the cooktop, the surface temperature is reduced, preventing burns during operation. The anti-slip texture on the surface of the heat insulation layer enhances friction during operation, improving safety. Meanwhile, the anti-slip pads on the bottom of the support feet further enhance the stability of the cooktop, preventing it from tipping over due to uneven ground or external forces.
[0018] In summary, this utility model, through its reasonable structural design and functional configuration, solves the shortcomings of existing floor stoves in terms of upper and lower zone temperature control and fume extraction, and has significant practicality and inventiveness.

[0025] This utility model relates to a floor stove with upper and lower zone temperature control and fume extraction. Its structure is rationally designed and its functions are complete, effectively solving the problems of existing floor stoves that cannot achieve independent temperature control in upper and lower zones and have low fume extraction efficiency during cooking. The following is in conjunction with the attached... Figure 1 To be continued Figure 5 The specific embodiments of this utility model will be described in detail with reference to the accompanying drawings.
[0026] like Figure 1 As shown, the cooktop 1 is the core component of this invention. It has a rectangular box structure and is internally divided into two independent heating areas, an upper heating chamber 3 and a lower heating chamber 4, by a partition plate 2. The partition plate 2 is horizontally positioned in the middle of the cooktop 1, evenly dividing the internal space into upper and lower parts to ensure that the heat distribution between the upper heating chamber 3 and the lower heating chamber 4 does not interfere with each other. The partition plate 2 is preferably made of a high-temperature resistant metal to withstand prolonged use in high-temperature environments. A vent 12 is provided in the middle of the partition plate 2, and an adjustable baffle 13 is provided inside the vent 12. The adjustable baffle 13 is movably connected to the partition plate 2 via a rotating shaft 14 and extends to the outside of the cooktop 1 via a handle 15, allowing the user to manually adjust the opening angle of the baffle 13. A sealing strip made of silicone material is provided on the edge of the adjustable baffle 13 to enhance the sealing between the baffle 13 and the vent 12, thereby preventing heat from being lost disorderly through the vent 12.
[0027] like Figure 2As shown, the first heating unit 5 is installed at the bottom of the upper heating chamber 3, and the second heating unit 6 is installed at the bottom of the lower heating chamber 4. Both are fixed to the bottom of their respective chambers with bolts to ensure stable installation. Both the first heating unit 5 and the second heating unit 6 include a heating plate and a heating tube embedded within the heating plate. The surface of the heating plate has several evenly distributed protrusions, with a height of 2mm to 5mm, used to increase the heating area and improve heat conduction efficiency. The first heating unit 5 and the second heating unit 6 are connected to an external power supply via wires and each is equipped with an independent temperature control device 7. The temperature control device 7 is located on the outside of the stove body 1 and is used to set the temperature via a knob or touch screen, thereby achieving independent temperature control of the upper heating chamber 3 and the lower heating chamber 4. The control signal of the temperature control device 7 is transmitted to the heating unit via wires to precisely regulate the power output of the heating tube, ensuring that the temperature in both chambers can be flexibly adjusted according to user needs.
[0028] The top of the stove body 1 is equipped with a fume extraction assembly, which includes a fume collection hood 8 and an exhaust pipe 9. For example... Figure 3 As shown, the fume collection hood 8 is fixed to the top of the stove body 1 and covers the opening area of the heating chamber 3. A guide plate 10 is provided on its inner side. The guide plate 10 has an arc-shaped design, with its upper end inclined towards the exhaust duct 9 to guide the fumes along a preset path. Several evenly distributed guide grooves are provided on the surface of the guide plate 10, with a semi-circular cross-section to reduce the adhesion of fumes on the guide plate 10. A fan 11 is located on the top of the fume collection hood 8. The fan 11 is fixed to the inner side of the fume collection hood 8 by a bracket, with its air inlet aligned with the end of the guide plate 10 and its air outlet connected to the exhaust duct 9. The blades of the fan 11 are made of stainless steel and coated with an oil-resistant coating to reduce the accumulation of fumes on the blades, thereby ensuring the efficient operation of the fan 11. One end of the exhaust duct 9 is connected to the fume collection hood 8, and the other end extends to the external exhaust system. The exhaust duct 9 has an internal filter screen composed of multiple layers of metal wire mesh, each layer having a pore size of 0.5mm to 1mm, used to intercept particulate matter in the fumes. The filter screen has slots on both sides that engage with the inner wall of the exhaust duct 9 for easy disassembly and cleaning.
[0029] The outer side of the stove body 1 is equipped with a heat insulation layer made of high-temperature resistant material, with a thickness of 10mm to 20mm. This layer is used to reduce the surface temperature of the stove body 1 and prevent burns during operation. The outer surface of the heat insulation layer has anti-slip textures distributed in a grid pattern to enhance friction during operation. Four support feet 16 are located at the bottom of the stove body 1, situated at each of the four corners. Figure 5 As shown, the bottom of the support foot 16 is provided with an anti-slip pad 17, which is made of rubber material and is used to enhance the stability of the stove body 1 and prevent slippage.
[0030] The working principle of this utility model is as follows: The user first sets the target temperature of the upper heating chamber 3 and the lower heating chamber 4 respectively through the temperature control device 7. The first heating unit 5 and the second heating unit 6 start heating according to the instructions of the temperature control device 7. The protrusions on the surface of the heating plate can increase the heating area and improve the heat conduction efficiency, thereby quickly raising the temperature inside the chamber. During the cooking process, the user can adjust the opening angle of the adjustable baffle 13 through the handle 15 according to actual needs to control the heat exchange between the upper and lower heating chambers. For example, when it is necessary to completely isolate the upper and lower chambers, the baffle 13 can be closed; when a certain degree of heat transfer is required, the baffle 13 can be opened to an appropriate angle.
[0031] During cooking, the fumes generated rise with the hot airflow to the opening area of the upper heating chamber 3 and are captured by the fume collection hood 8. The guide plate 10 inside the fume collection hood 8, through its arc-shaped design and guide channel structure, guides the fumes along a preset path, reducing fumes stagnation within the hood. When the fan 11 is started, its air inlet aligns with the end of the guide plate 10, efficiently extracting the fumes and guiding them into the exhaust duct 9. The filter inside the exhaust duct 9 intercepts particulate matter in the fumes, preventing it from entering the external exhaust system and thus reducing environmental pollution. Users can regularly disassemble and clean the filter to ensure the long-term efficient operation of the fume extraction components.
[0032] The heat insulation layer on the outer side of the cooktop 1 effectively reduces the surface temperature of the cooktop 1, preventing burns to the user during operation. The anti-slip texture on the surface of the heat insulation layer enhances friction during operation, improving safety. Meanwhile, the anti-slip pads 17 at the bottom of the support feet 16 further enhance the stability of the cooktop 1, preventing it from tipping over due to uneven ground or external forces.
[0033] The above structure and operation process together constitute the technical solution of this utility model, realizing the functions of independent temperature control in the upper and lower zones and efficient oil fume extraction, thus meeting the diverse needs of users in the cooking process.
[0034] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.
[0035] In actual cooking, the user first sets the target temperatures for the upper heating chamber 3 and the lower heating chamber 4 using the temperature control device 7. For example, when preparing dishes requiring different heating conditions, the upper heating chamber 3 can be set to 200℃ for frying, while the lower heating chamber 4 can be set to 150℃ for slow-cooking. The temperature control device 7 transmits the temperature setting signal to the first heating unit 5 and the second heating unit 6 via wires, activating the heating functions of the two chambers respectively. Due to the raised structure on the surface of the heating plate, heat can be evenly distributed throughout the bottom of the chamber, and the temperature inside the chamber can be quickly raised to the target value through heat conduction. During this process, the design of the partition plate 2 ensures that the heat between the upper and lower heating chambers does not interfere with each other, thus achieving the technical effect of independent temperature control.
[0036] When a certain degree of heat exchange is required, the user can adjust the opening angle of the adjustable baffle 13 by rotating the handle 15. For example, in some cooking scenarios, if it is desired that some of the heat from the lower heating chamber 4 be transferred to the upper heating chamber 3 to save energy, the baffle 13 can be opened to an angle of 30° or 45°. At this time, the vent 12 allows heat to flow upward from the lower heating chamber 4, but due to the presence of the sealing strip, the range of heat flow is limited, avoiding excessive heat diffusion that could affect temperature control accuracy. This design allows users to flexibly adjust the heat distribution between the upper and lower chambers according to actual needs, solving the problem that traditional floor stoves cannot independently control the temperature of different zones.
[0037] During cooking, the fumes generated rise with the hot airflow to the opening area of the upper heating chamber 3 and are captured by the fume collection hood 8. The guide plate 10 inside the fume collection hood 8 guides the fumes along a preset path through its arc-shaped design, reducing the residence time of the fumes within the hood. Simultaneously, the semi-circular cross-section design of the guide channel reduces the amount of fumes adhering to the guide plate 10, thereby improving fume extraction efficiency. When the fan 11 starts, its air inlet aligns with the end of the guide plate 10, quickly extracting the fumes and guiding them into the exhaust duct 9. The oil-resistant coating on the surface of the fan 11 blades effectively reduces grease buildup, ensuring long-term efficient operation of the fan.
[0038] The filter inside the exhaust duct 9 consists of multiple layers of metal wire mesh, each with a pore size of 0.5mm to 1mm, effectively trapping particulate matter in cooking fumes. Because the filter has slots on both sides, users can easily disassemble it for cleaning, ensuring the continuous and efficient operation of the fume extraction components. Furthermore, the extended design of the exhaust duct 9 allows for seamless connection to external exhaust systems, further enhancing fume extraction and reducing air pollution in the kitchen.
[0039] The heat insulation layer on the outer side of the cooktop 1 is 10mm to 20mm thick and made of high-temperature resistant material, which can significantly reduce the surface temperature of the cooktop 1. For example, under prolonged high-power operation, the heat insulation layer can control the surface temperature of the cooktop within a safe range, preventing burns to the user during operation. The anti-slip texture on the surface of the heat insulation layer enhances the friction when the user touches it, improving safety. At the same time, the anti-slip pads 17 at the bottom of the support feet 16 are made of rubber material, which can adapt to different ground environments, further enhancing the stability of the cooktop 1 and preventing the cooktop from tipping over due to uneven ground or external forces.
[0040] In summary, this utility model, through the combination of the above steps and principles, achieves independent temperature control in the upper and lower zones and efficient fume extraction, meeting the needs of users in diverse cooking scenarios and demonstrating significant practicality.
[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
