Third, electric wire coil electric grills, which have functions of frying, roasting, and deep-frying, are small and delicate, and the heat is quickly transferred during heating, and the roasted meat is evenly heated. It has a uniquely designed heat storage structure, stepless temperature adjustment, convenient operation, and environmental protection and energy saving.

[0004] Existing electric griddles have a relatively single form. For example, patent document CN210961565U discloses an intelligent constant temperature electric griddle, which includes an outer frame. Both sides of the outer frame are fixedly connected with support plates. An insulating plate is movably connected inside the support plates, and a heating panel is movably connected inside the insulating plate. A return-shaped plate is fixedly connected to the periphery of the inner wall of the insulating plate, and oil collecting grooves are respectively opened on the front and back of the top of the heating panel. A oil guiding groove is opened on the top of the heating panel and on one side of the two oil collecting grooves. It mainly relates to the technical field of electric griddles. This intelligent constant temperature electric griddle can effectively collect the grease of meat through the support plates fixedly connected to both sides of the outer frame, which can reduce the intake of grease content and reduce the harm to health. By the top of the return-shaped plate contacting the bottom of the heating panel, the maintenance of the heating panel is improved. At the same time, the intelligent control can keep the electric griddle in a constant temperature state, making it more convenient to use.

Detailed Embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Reference Figures 1 to 6 , a concentrated energy electric grill, including a base 1, a baking tray 2 and a top cover 3 arranged in sequence from bottom to top, and the base 1, the baking tray 2 and the top cover 3 are sleeved on the same connecting piece, and a food accommodating space 4 is formed between the top cover 3 and the baking tray 2;

[0031] The top cover 3 is provided with a first heating component 5, and the first heating component 5 is arranged towards the upper end surface of the baking tray 2; a second heating component 6 is arranged in the base 1, and the second heating component 6 is arranged towards the lower end surface of the baking tray 2;

[0032] A smoke filtering component 7 is arranged in the base 1, and a smoke suction port 8 and a smoke exhaust port 9 are further opened on the base 1. The inlet end of the smoke filtering component 7 is communicated with the smoke suction port 8, the outlet end of the smoke filtering component 7 is communicated with the smoke exhaust port 9, and the smoke suction port 8 is located on the periphery of the baking tray 2.

[0033] The above content is the basic content of the present invention, which proposes a brand-new structural design for the electric grill, replacing the existing structure of the electric baking tray 2, and eliminating several major pain points of the original product. One is that a top cover 3 is arranged above the baking tray 2, which can block and divert the oil smoke to a certain extent to prevent it from directly flowing towards the user and reduce the escape of oil smoke; the other is that a dual heating system composed of a first heating component 5 and a second heating component 6 is adopted, and is arranged on the upper and lower sides of the baking tray 2, so that the food is evenly heated on the upper and lower sides during the baking process, without the need to flip the food, and the situation of burning is also greatly reduced; the third is that a smoke filtering component 7 is adopted to extract and filter the oil smoke during the food baking process and discharge the filtered clean air outwards, greatly reducing the impact of oil smoke on the surrounding environment during use.

[0034] In some embodiments of the present invention, the electric grill is set to a closed structure to form a closed food baking environment. The specific method is: further including a transparent heat preservation cover 10, the upper end of the transparent protection cover is connected to the top cover 3, and the lower end is connected to the base 1. After adopting the transparent heat preservation cover 10, during the use of the electric grill, the generated oil smoke will be blocked from the outside world, and can only be sucked in by the smoke suction port 8 on the base 1 and discharged clean air through the processing of the smoke filtering component 7 by the smoke exhaust port 9. On the other hand, the heat preservation cover is in a transparent form, which is convenient for users to clearly observe the food on the baking tray 2 through the transparent heat preservation cover 10, so as to better control the process during processing and bake more delicious food.

[0035] A general cover may be directly fixed to the top cover 3 or the base 1 and cannot be disassembled. It can only achieve a closed barbecue method singly and is not easy to wipe and clean. In addition, in order to be able to disassemble the cover, structures such as screws or buckles are generally selected for installation and adaptation. The disassembly and assembly process is relatively cumbersome, and due to factors such as the wall thickness (relatively thin) and material (mainly plastic) of the cover itself, the cover is prone to deformation or damage after repeated disassembly and assembly, resulting in the inability to continue disassembly and normal use. In order to facilitate disassembly and assembly and at the same time not cause damage to the transparent heat preservation cover 10 body during repeated disassembly and assembly, the preferred setting adopted here is that the transparent heat preservation cover 10 forms a magnetic attraction connection with the top cover 3 and the base 1 respectively.

[0036] More specifically, since the material of the transparent heat preservation cover 10 itself does not have magnetism, magnetic strips are selected to be embedded at the bottom and top of the transparent heat preservation cover 10. If the materials of the base 1 and the top cover 3 themselves have magnetism, the magnetic strips can directly adsorb and connect the transparent heat preservation cover 10 with the base 1 and the top cover 3; if the materials of the base 1 or / and the top cover 3 themselves do not have magnetism, magnetic substances can be set on the base 1 or / and the top cover 3 to adsorb with the magnetic strips, thereby realizing the quick disassembly and assembly operation of the transparent heat preservation cover 10 relative to the base 1 / top cover 3.

[0037] In some embodiments of the present invention, a horn-shaped reflector 11 is further provided in the top cover 3, which is characterized in that it can converge heat energy and guide the heat energy in a specific direction, making the heating and baking efficiency of food higher.

[0038] The reflector 11 is generally made of metal materials such as copper and aluminum, so its own temperature will also increase during use. Since the upper end of the top cover 3 is provided with an electronic control panel assembly 27 and the position of the reflector 11 is not far from the top cover 3, too high a temperature will directly cause the temperature of the electronic control panel assembly 27 to rise, and seriously will cause the electronic control panel assembly 27 to crash, and then the entire electric grill will not be able to be used. In order to solve the above problems, a targeted heat dissipation structure is provided here, specifically: a heat dissipation port 12 is opened on the top cover 3, and the heat dissipation port 12 is arranged between the reflector 11 and the inner top of the top cover 3 to timely dissipate the heat through the heat dissipation holes and reduce the working environment temperature of the electronic control panel assembly 27.

[0039] Different from the existing electric grill structure, another major innovation of the present invention is that the connecting member is a rotating support column 13. A rotating motor 14 is provided in the base 1. The output end of the rotating motor 14 is in transmission cooperation with the rotating support column 13. The rotating support column 13 is in transmission connection with the baking tray 2, and the rotating support column 13 is in rotational cooperation with the top cover 3. With the above solution, the baking tray 2 can be rotated relative to the top cover 3 / base 1 through the rotating motor 14 and the rotating support column 13, so that the food on the baking tray 2 is baked completely evenly, and the sides of the food also receive more uniform heat, eliminating the phenomenon of some food being cooked and some raw, and thus cooking delicious food.

[0040] Regarding the preferred basic setting of the oil fume filtering component 7: it includes an oil fume passage 15 connecting the smoking port 8 and the exhaust port 9, a smoking fan 16 and an oil fume filtering chamber 17 connected to the oil fume passage 15, and a filtering liquid is provided in the oil fume filtering chamber 17. During use, the oil fume generated by the food on the baking tray 2 enters the base 1 along the smoking port 8 under the action of the smoking fan 16, and then flows to the oil fume filtering chamber 17 through the oil fume passage 15. The filtering liquid in the oil fume filtering chamber 17 adsorbs the oil fume substances to purify the dirty air into clean air, and discharges it out of the base 1 along the exhaust port 9, so that the whole baking process has a good smokeless effect and the user has a better use experience.

[0041] In order to expand the practical functions on the basis of the above structure without adding complex components, the improvement made is: referring to Figure 6 , the oil fume filtering chamber 17 is separated into a water purification area 18 and a filtering area 19 by a partition; the filtering liquid is placed in the filtering area 19, and the filtering area 19 has an inlet and outlet opening; clean water is placed in the water purification area 18, and a closed cover plate 20 is provided on the water purification area 18 (to prevent being contaminated by oil stains); a number of spray holes 21 are opened on the circumference of the rotating support column 13, and a rising channel 22 is provided in the rotating support column 13. One end of the rising channel 22 is communicated with the water purification area 18, and the other end is communicated with the spray holes 21. Through the setting of the partition, the oil fume filtering chamber 17 is divided into two parts in structure (the water purification area 18 and the filtering area 19), and at the same time, the functions are also divided into two parts. The use process of oil fume filtering is the same as the foregoing and will not be elaborated here. The use method of the water purification area 18 is that the clean water in the water purification area 18 can enter the rotating support column 13 along the rising channel 22 and then be sprayed out by the spray holes 21. Therefore, the clean water can fall into the food on the baking tray 2 to humidify the food and improve the edible taste.

[0042] With richer functions, further processing of the purified water is carried out, specifically: a steam generating device 23 is further provided in the base 1, and the purified water area 18 is communicated with the rising channel 22 through the steam generating device 23. Through the setting of the steam generating device 23, the purified water can be converted into steam and enter the food accommodating space 4 in the form of steam, which not only fully humidifies the food but also provides another processing effect for steaming food.

[0043] In the present invention, under the action of the rotating motor 14, the rotating support column 13 can also rotate, so a certain centrifugal force will be generated. Under the action of this centrifugal force, the purified water or steam can be sprayed more quickly and efficiently towards the food accommodating space 4, and the spraying range is farther.

[0044] During the use of the electric grill, more or less a certain amount of oil and water (the oil coated or the oil of the food itself) will be generated. If this part of the oil and water remains on the baking tray 2, on the one hand, it will directly cause uneven baking effects on all sides of the food, and on the other hand, it is not convenient for cleaning and maintenance; in addition, the accumulation of oil and water is likely to generate a larger amount of oil fumes, which in turn affects the use effect of the oil fume filtering component 7. To overcome the above defects, the structural concept proposed in this embodiment is: the baking tray 2 is in the shape of a bowl with a higher outer side and a lower inner side, an oil collecting groove 24 is provided at the center of the baking tray 2, and a plurality of oil guiding grooves 25 communicating with the oil collecting groove 24 are provided on the baking tray 2 in a ring shape, and the oil collecting groove 24 has an oil draining hole 26 communicating with the oil fume filtering chamber 17. After the oil and water are generated, the oil and water can automatically flow along the oil guiding grooves 25, the oil collecting groove 24, and the oil draining hole 26 into the oil fume filtering chamber 17 under the influence of gravity to timely drain the oil and water on the baking tray 2 and the food.

[0045] Refer to Figure 5 , in the present invention, the baking tray 2 has various shapes to adapt to the baking requirements of different foods.

[0046] The above are only the preferred embodiments of the present invention, and do not impose any limitations on the present invention. Any simple modifications, changes, and equivalent structural changes made to the above embodiments according to the technical essence of the invention still fall within the protection scope of the technical solution of the present invention.
