Description

Technical Field

[0001] This invention relates to the field of grilling equipment technology, and in particular to a dual-purpose grilling sandwich maker and its usage method. Background Technology

[0002] In the existing technology, sandwich makers, as small household kitchen appliances, adopt a core "folding top cover-base" structure. The top cover and base are hinged together, and heating panels are provided on the opposite sides of both. They are also equipped with sandwich-specific baking trays with guards. When in use, bread slices and ingredients are placed on the baking tray, the top cover is folded to make the heating panels fit, and the ingredients are heated and pressed by the heating module to achieve rapid sandwich making. Its core function focuses on the single heating and pressing scenario of sandwiches.

[0003] However, existing sandwich makers have a significant drawback of limited functionality, making it difficult to meet users' diverse cooking needs: their baking trays are mostly slotted structures adapted for sandwiches, which can only heat and press bread and thin slices of food, and cannot be adapted to professional grilling scenarios such as steak, scallion pancakes, and multiple fried eggs. If users need to grill such foods, they need to purchase an additional grilling machine, which not only increases economic costs but also takes up kitchen storage space.

[0004] While some models attempt to achieve grilling by "removing the sandwich grill pan and using the heating panel directly", the heating panel has a limited area and no anti-splatter structure, which easily leads to uneven heating of food and oil splattering, resulting in poor grilling effect. Even if a few models claim to be "dual-purpose", the grilling function is merely a formality because the structure is not optimized for grilling scenarios, and it cannot achieve the effect of a professional grill. Summary of the Invention

[0005] The main objective of this invention is to provide a dual-purpose sandwich maker and its usage method. By designing a hinged, folding, and flat dual-form top cover, a dual-purpose baking tray assembly, an integrated fume extraction structure, and a precise temperature control linkage and stable support mechanism, it achieves both sandwich pressing and professional grilling in one machine. Simultaneously, it directionally captures the fumes generated during cooking, ensuring the equipment's stable and reliable form, simplifying operation and maintenance procedures, ultimately reducing user costs and space requirements, and improving cooking quality and overall user experience.

[0006] To achieve the above objectives, the present invention proposes a dual-purpose grill sandwich maker, including a base; and further comprising, A top cover is hinged to the base and can rotate relative to the base to have a folded state and an unfolded state; in the folded state, the top cover can fit against the base; in the unfolded state, the top cover and the base are arranged flat and a communication area is formed between them near the hinge. The heating module includes a first heating panel and a second heating panel respectively disposed on the top cover and the base; both the first heating panel and the second heating panel are electrically connected to a temperature control unit. A dual-purpose baking pan assembly includes a sandwich baking pan set and a grill pan; the sandwich baking pan set includes a first baking pan and a second baking pan respectively adapted to a first heating panel and a second heating panel; the grill pan can cover the first heating panel and the second heating panel in the unfolded state through a connecting area. The fume extraction assembly is integrated on the base and includes a main suction head, an exhaust box, and a suction pump. The exhaust box is located on the side of the base, has a built-in filter assembly, and is connected to the suction pump. The exhaust box is connected to the main suction head through a connecting pipe. The main suction head protrudes from the surface of the second heating panel, and has a suction hole on its top, configured as follows: The first baking tray has a groove. When the sandwich baking tray assembly is installed in the folded state, the main suction head cooperates with the through hole on the second baking tray and the groove on the first baking tray accommodates the main suction head, so that the air intake hole of the main suction head is connected with the space formed between the first baking tray and the second baking tray to capture oil fumes and exhaust water vapor. The grill pan is provided with positioning holes. When the grill pan is installed in the unfolded state, the main suction head passes through the positioning holes on the grill pan, so that the suction hole is exposed above the grill pan to capture the oil fumes generated during grilling.

[0007] In one possible implementation, the main suction head is in the shape of a boss, including an extension fixedly disposed on the second heating panel, the extension extending upward perpendicular to the second heating panel; and the suction hole is opened on the top surface of the extension.

[0008] In one possible implementation, a plurality of air intake holes are provided, and the plurality of air intake holes are evenly distributed in a circular pattern on the top surface of the extension; the griddle is provided with positioning holes corresponding to the formation position of the extension, and the top surface of the extension can pass through the positioning holes so that the air intake holes are above the griddle; it also includes an auxiliary suction head protruding on the griddle and corresponding to the position of the first heating panel, the auxiliary suction head is provided with auxiliary suction holes, and the auxiliary suction head is connected to the suction holes of the main suction head through a suction pipe; so as to form a suction area covering the area of ​​the first heating panel.

[0009] In one possible implementation, both the first and second baking pans have a retaining edge on their surfaces, which is used to enclose and form a sandwich slot for accommodating food in the folded state.

[0010] In one possible implementation, the frying pan is provided with an oil-blocking strip arranged around the positioning hole.

[0011] In one possible implementation, an inspection port is provided on one side of the exhaust box, and a cover plate is detachably provided on the exhaust box to seal the inspection port; the filter assembly is detachably installed inside the exhaust box to filter and purify the inhaled oil fumes, and facilitates subsequent cleaning or replacement.

[0012] In one possible implementation, a handle is fixedly connected to the top cover. The handle includes a pair of connecting parts fixedly disposed on both sides of the top cover. One end of the pair of connecting parts is hinged to the base, and the other end extends away from the top cover to form a support part. The support part can be used to make the first heating panel and the second heating panel parallel and at the same height when the top cover is rotated relative to the base to the unfolded state.

[0013] In one possible implementation, a support adjustment assembly is provided on one side of the base opposite to the top cover. The support adjustment assembly includes a rotating shaft rotatably mounted on the base, one end of which is connected to a motor, which is connected to a control module. A limiting plate extending toward the top cover is also eccentrically mounted on the rotating shaft. The limiting plate is located on the side of the top cover away from the first heating panel, and the limiting plate can be fitted against the top cover. The motor can drive the limiting plate to rotate to limit the rotation angle of the top cover relative to the base.

[0014] In one possible implementation, both the suction pump and the temperature control unit are electrically connected to a control module. The control module can control the temperature control unit to heat the first heating panel and the second heating panel, as well as control the start and stop of the suction pump.

[0015] A method for using a dual-purpose grill sandwich maker includes the following steps: S1: Select the appropriate baking pan according to your cooking needs. If you need to make a sandwich, proceed to step S2; if you need to grill or fry the ingredients, proceed to step S3. S2: Sandwich making process: Install the first and second baking trays of the sandwich baking tray assembly onto the first and second heating panels respectively, ensuring the main exhaust fan is compatible with the second baking tray; rotate the top cover to the folded position, so that the top cover fits snugly against the base, and the edges of the first and second baking trays form a sandwich compartment; activate the temperature control unit to adjust the first and second heating panels to the target temperature, and simultaneously activate the fume extraction component; place the ingredients into the sandwich compartment, and after the ingredients are heated, turn off the temperature control unit and the fume extraction component, rotate the top cover to unfold, and remove the ingredients; S3: Grilling process: Rotate the top cover to the unfolded state so that the top cover and the base are flat. Then install the grilling pan on the first heating panel and the second heating panel in the unfolded state, so that the main suction head is compatible with the grilling pan. Start the temperature control unit to adjust the first heating panel and the second heating panel to the target temperature, and simultaneously start the fume extraction component. Place the food on the surface of the grilling pan. After the food is grilled, turn off the temperature control unit and the fume extraction component, and remove the food.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. The sandwich maker features a structural design with a hinged top and base, and a dual-purpose grill pan assembly. In the folded state, the edges of the grill pan create a sandwich groove, accommodating heat pressing needs. In the unfolded state, the flat grill pan covers the dual heating panels, suitable for grilling steaks, scallion pancakes, and other grilling scenarios. This eliminates the need for a separate grill, reducing user expenses and avoiding the need for multiple devices to occupy kitchen storage space, thus addressing the core pain point of traditional sandwich makers' limited functionality.

[0017] 2. Relying on the fume extraction structure of "the main suction head and exhaust box protruding on the second heating panel", combined with the auxiliary suction head of the frying pan: during cooking, the fumes are directly captured by the main and auxiliary suction heads, purified by the filter components and discharged, avoiding the spread of fumes and pollution of cabinets and walls; at the same time, it reduces the health risks of users inhaling fumes, especially suitable for use in open kitchens, solving the problem of uncontrolled fumes in traditional models; At the same time, the negative pressure generated by the suction head can simultaneously remove the moisture produced by the heating of the ingredients in the slot, preventing moisture accumulation that causes the bread to absorb moisture and become soft and collapse, ensuring that the sandwich crust remains crispy, and solving the problem of bread becoming soft after hot pressing in traditional sandwich machines.

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Example 1

[0023] like Figure 1-11 As shown, the present invention proposes a dual-purpose grill sandwich maker, including a base 1, on which an exhaust box 91 is integrated on the side, and space is reserved inside for installing a connecting pipe 93, a suction pump 92 and a control module; the top cover 2 and the base 1 are connected only by a handle 11, the handle 11 is provided with a pair of connecting parts 110, which are respectively fixed on both sides of the top cover 2, one end of the connecting part 110 is rotatably connected to the base 1 by a pin to form a hinge structure, and the other end extends away from the top cover 2 to form a support part 111.

[0024] like Figure 1 , 5 As shown in Figure 7, when the top cover 2 rotates relative to the base 1 to the unfolded state, the support part 111 will contact the tabletop, stably supporting the top cover 2, ensuring that the first heating panel 4 and the second heating panel 5 remain parallel and at the same height, avoiding the problem of the top cover 2 shifting due to lack of support in the traditional hinge structure.

[0025] At the same time, such as Figure 9-11 As shown, a support adjustment assembly 12 is provided on one side of the base 1 opposite to the top cover 2. The rotating shaft 120 of this assembly is rotatably mounted on the metal frame of the base 1 via a bearing. The motor 121 is connected to one end of the rotating shaft 120 via a coupling. The limiting plate 122, which is eccentrically set on the rotating shaft 120, is located on the side of the top cover 2 away from the first heating panel 4. When the motor 121 drives the rotating shaft 120 to rotate, the limiting plate 122 will rotate eccentrically with the rotating shaft 120 and fit against the back of the top cover 2. By adjusting the rotation angle of the limiting plate 122, the maximum rotation range of the top cover 2 can be precisely limited. This can meet the flatness requirement when unfolding for grilling and also provide stable support when processing sandwiches and adding ingredients halfway open, further improving the reliability of shape control.

[0026] The heating module and temperature control unit 6 are both located in the cavity inside the base 1 and the top cover 2, while the main control module is located on the base 1. All three are designed based on commonly used technologies in existing small household appliances.

[0027] Specifically, such as Figure 2 As shown, both the first heating panel 4 and the second heating panel 5 of the heating module are made of metal. A connecting area 3 is provided between the two heating panels. Heating elements are attached to the back. The heating elements are mature graphene heating films or metal heating tubes 13. In this embodiment, metal heating tubes 13 are used. The metal heating tubes 13 are attached to the back of the heating panels with high-temperature resistant adhesive to ensure efficient heat transfer. The temperature control unit 6 adopts an existing bimetallic strip temperature controller or an NTC temperature sensor, which is integrated into the edge of the heating panel. It can detect the temperature of the heating panel in real time to avoid overheating. The main control module is an integrated circuit board installed in an independent chamber inside the base 1. It is connected to the heating module, temperature control unit 6, suction pump 92 and motor 121 through wires. It can receive commands from external control buttons to realize the start and stop of each component and parameter adjustment, ensuring structural stability and controllable cost.

[0028] And such Figure 5-8 The dual-purpose baking tray assembly is the core of the function switching. The first baking tray 71 and the second baking tray 72 of the sandwich baking tray assembly 7 are both made by die casting and are coated with a ceramic oil non-stick coating commonly used in the prior art to reduce food sticking.

[0029] Specifically, such as Figure 6As shown, both the first baking tray 71 and the second baking tray 72 have integrally formed retaining edges 73. When the top cover 2 is in the folded state, the retaining edges 73 of the two baking trays will align with each other and together form a closed sandwich groove 74 to prevent the food from overflowing during the heating process. Crucially, the second baking tray 72 has a through hole 720 corresponding to the position of the main suction head 90. The shape of the through hole 720 is adapted to the boss-like structure of the main suction head 90, allowing the extension 901 of the main suction head 90 to pass through the through hole 720. The first baking tray 71 has a groove 721 corresponding to the position of the main suction head 90. The depth of the groove 721 matches the height of the extension 901 of the main suction head 90. When the top cover 2 is folded, the extension 901 of the main suction head 90 will be embedded in the groove 721. This not only prevents the main suction head 90 from obstructing the tight fit of the two baking trays, but also ensures that the sandwich groove 74 is in a closed state, laying a structural foundation for the directional discharge of oil fumes and moisture.

[0030] And such Figure 8 As shown, the griddle 8 is an integral flat structure, covering the first heating panel 4 and the second heating panel 5 in the unfolded state. A positioning hole 81 is provided corresponding to the position of the main suction head 90. During installation, the extension 901 of the main suction head 90 can pass through the positioning hole 81, so that the air intake 902 is exposed above the griddle 8. An auxiliary suction head 82 is also integrally formed on the side of the griddle 8 near the first heating panel 4. The auxiliary suction head 82 is connected to the air intake 902 of the main suction head 90 through the air intake pipe 84, and the joint of the air intake pipe 84 is sealed with a silicone sealing ring to ensure that the oil fumes will not leak. At the same time, an oil blocking strip 10 is also provided around the positioning hole 81 on the griddle 8. The oil blocking strip 10 can intercept the oil droplets splashed during frying and prevent the oil droplets from seeping into the connecting pipe 93 through the positioning hole 81, thus avoiding blockage of the air intake passage.

[0031] like Figure 3-4As shown, the main suction head 90 of the fume extraction assembly 9 is made of metal, and the protruding extension 901 is vertically fixed to the surface of the second heating panel 5. Air intake holes 902 are evenly distributed on the top surface of the extension 901. These air intake holes 902 are connected to the connecting pipe 93 through internal air passages. The connecting pipe 93 extends along the inside of the base 1 to the exhaust box 91 on the side. An inspection port 910 is provided on one side of the exhaust box 91. A cover plate 911 is detachably installed at the inspection port 910 via a sliding groove. A silicone sealing gasket can be installed on the inner side of the cover plate 911 to ensure... To ensure the airtightness of the exhaust box 91, a metal pre-filter and an activated carbon filter are placed sequentially inside the exhaust box 91 from the side near the connecting pipe 93 to the side near the suction pump 92. The metal pre-filter can intercept oil droplets in the fumes, while the activated carbon filter is used to absorb odors in the fumes. The suction pump 92 is installed at the end of the exhaust box 91 away from the connecting pipe 93, and its air outlet is connected to the exhaust grille on the outside of the exhaust box 91. When the suction pump 92 is started, a negative pressure is formed at the air intake hole 902 of the main suction head 90, thereby achieving directional capture and purification of fumes.

[0032] In actual use, if the sandwich making mode is selected, firstly, install the first baking tray 71 and the second baking tray 72 on the first heating panel 4 and the second heating panel 5 respectively, ensuring that the extension 901 of the main suction head 90 passes through the through hole 720 of the second baking tray 72, and that the groove 721 of the first baking tray 71 is aligned with the main suction head 90; then, rotate the top cover 2 to the folded state using the handle 11. At this time, the support part 111 of the handle 11 does not touch the table, and the limiting plate 122 rotates to a certain angle under the drive of the motor 121, so that the top cover 2 is in a half-open state when opened, which is convenient for operation of the top cover 2, and the baffles 73 of the two baking trays form a closed sandwich groove 74; then press the external control panel or the rotation button, and after receiving the command, the main control module starts the temperature control unit 6 and the heating module, adjusts the two heating panels to the target temperature, and simultaneously starts the suction pump 92. A negative pressure is created at the main suction head 90. After placing bread slices, bacon, cheese, and other ingredients into the sandwich trough 74, the top cover 2 is closed and the heating is waited for to complete. During this period, the oil fumes generated by the heating of the ingredients are sealed inside the sandwich trough 74 and can only enter the air intake 902 of the main suction head 90 through the through hole 720 of the second baking tray 72. Then, they enter the exhaust box 91 through the connecting pipe 93 and are filtered by the metal pre-filter and activated carbon filter in sequence. The clean air is then discharged from the exhaust grille. At the same time, the negative pressure created by the suction pump 92 will also remove excess moisture from the sandwich trough 74 to prevent moisture accumulation from causing the bread to absorb moisture and become soft, thus ensuring that the bread crust remains crisp. After the ingredients are heated, the main control module receives a temperature signal or a time signal and automatically shuts off the temperature control unit 6, the heating module, and the suction pump 92. The motor 121 drives the limit plate 122 to rotate and disengage from the top cover 2. The sandwich can be taken out by lifting the top cover 2 with the handle 11.

[0033] If the grilling mode is selected, first disassemble the sandwich grill pan assembly 7. Then, rotate the top cover 2 to the unfolded state using the handle 11. The support part 111 of the handle 11 contacts the tabletop, and the limiting plate 122 rotates under the drive of the motor 121 until it fits against the back of the top cover 2, ensuring that the first heating panel 4 and the second heating panel 5 are parallel and at the same height. Then, cover the first heating panel 4 and the second heating panel 5 with the grill pan 8, so that the extension part 901 of the main suction head 90 passes through the positioning hole 81 of the grill pan 8. At the same time, adjust the position of the grill pan 8 so that the suction pipe 84 of the auxiliary suction head 82 is connected and sealed with the suction hole 902 of the main suction head 90. Press the external control button, and the main control module controls the temperature control unit according to the selected grilling mode. 6. Adjust the two heating panels to the corresponding temperatures and simultaneously start the suction pump 92. Place ingredients such as steak and eggs on the surface of the grill pan 8. The fumes generated by the heating of the ingredients are directly captured by the air intake 902 of the main suction head 90 near the area of ​​the second heating panel 5, while the fumes near the area of ​​the first heating panel 4 are sucked in by the auxiliary suction 83 of the auxiliary suction head 82. They are then drawn into the main suction head 90 through the suction pipe 84 and together enter the exhaust box 91 through the connecting pipe 93 for filtration and discharge. During the grilling process, the oil-blocking strip 10 of the grill pan 8 will intercept splashed oil droplets to prevent them from seeping into the positioning hole 81. After the ingredients are grilled, turn off the temperature control unit 6, the heating module, and the suction pump 92, and remove the grill pan 8 for cleaning.

[0034] Based on the above structure, the core advantage of the suction head in sandwich mode stems from the combination of the enclosed sandwich trough 74 and the directional suction passage. On the one hand, the through hole 720 of the second baking tray 72 and the groove 721 of the first baking tray 71 make the main suction head 90 the only exhaust channel for oil fumes and moisture in the sandwich trough 74, avoiding the problem of oil fumes spreading to the kitchen or lingering in the trough in traditional models, reducing odor residue and health risks; on the other hand, the negative pressure generated by the suction pump 92 accelerates the airflow in the trough, promptly removing moisture and disrupting the conditions for bread to absorb moisture and become soggy, ensuring the taste.

[0035] In grilling mode, the combination of the main suction head 90 and the auxiliary suction head 82 achieves comprehensive oil fume coverage of the dual heating panel area, solving the problem of incomplete coverage by a single suction head. Meanwhile, the design of the oil-blocking strip 10 and the detachable filter component 912 ensures unobstructed airflow and reduces daily maintenance difficulty. Furthermore, the coordinated structure of the handle 11 and the support adjustment component 12 ensures the stability of the heating panel in both cooking modes, providing structural assurance for even heating of the food. Example 2

[0036] Based on Example 1, this example provides a method for using a dual-purpose grill sandwich maker, explaining the general operating procedures for different cooking scenarios to demonstrate its adaptability and operating logic in processing various ingredients.

[0037] First, perform step S1: Select the corresponding baking pan component according to the actual cooking needs. If you need to perform closed heat pressing of the food, select sandwich baking pan 7 and perform step S2; if you need to perform open grilling of the food, select grill pan 8 and perform step S3.

[0038] Step S2 (Closed Hot Press Process): Install the first baking tray 71 of the sandwich baking tray assembly 7 onto the first heating panel 4 of the top cover 2, ensuring a tight fit through the panel's preset positioning structure. Install the second baking tray 72 onto the second heating panel 5 of the base 1, adjusting its position to ensure precise alignment between the main suction head 90 and the matching structure of the second baking tray 72, guaranteeing unobstructed airflow. Then, rotate the top cover 2 to a folded state, allowing it to fit tightly against the base 1. At this point, the edges 73 of the first and second baking trays 71 and 72 form a closed hot press space. Activate the equipment's temperature control unit 6, adjusting the first heating panel 4 and the second heating panel 5 to the target temperature according to the characteristics of the ingredients. Simultaneously, the fume extraction assembly 9 is activated, creating a directional airflow within the hot press space. Place the ingredients to be processed into the hot press space, close the top cover 2 to maintain a closed state, and allow the fumes and moisture generated during heating to enter the fume extraction assembly 9 through the main suction head 90, where they are filtered and then discharged. Once the ingredients have been processed, turn off the temperature control unit 6 and the fume extraction component 9, rotate the top cover 2 to disengage it from its folded state, and then remove the processed ingredients.

[0039] Step S3 (Open-type grilling process): Disassemble the sandwich grill pan assembly 7 and install the grill pan 8 onto the first heating panel 4 and the second heating panel 5 in their unfolded state. Ensure that the grill pan 8 completely covers both heating panels and that the main suction head 90 is compatible with the corresponding structure of the grill pan 8, ensuring a complete airflow path. Rotate the top cover 2 to the unfolded state, so that the top cover 2 and the base 1 are set flat, forming a stable grilling support surface. Activate the temperature control unit 6 and adjust the first heating panel 4 and the second heating panel 5 to the corresponding temperatures according to the food requirements. The fume extraction component 9 is activated simultaneously, forming a suction range covering the entire area of ​​the grill pan 8. Place the food to be processed on the surface of the grill pan 8. The fumes generated during the grilling process are captured by the main suction head 90 and the auxiliary suction structure, filtered and purified by the fume extraction component 9, and then discharged. Once the food is grilled, turn off the temperature control unit 6 and the fume extraction component 9, and remove the processed food directly from the surface of the grill pan 8.

[0040] This usage method adapts to different cooking scenarios through a unified operating logic. Whether it is closed hot pressing or open grilling, it can achieve efficient processing through grill plate switching, status adjustment and component linkage, and keep the oil fumes under control and the operation convenient throughout the process, which reflects the core advantage of the equipment as a "multi-functional machine".
