Description

Technical Field

[0001] This utility model relates to an air fryer, specifically an air fryer outer protective structure. Background Technology

[0002] An air fryer is a new type of household appliance that uses high-speed air circulation technology to fry food. Compared to traditional electric fryers, it reduces oil content by up to 80%, is easy to clean, and is both safe and economical, making it very popular. Some existing air fryers have a large opening on three sides below the control panel. The opening is closed by a rotating, moving, and opening / closing outer cover. For example, Chinese patent application number 202322767194.5, authorized on June 4, 2024, entitled "A Pull-Up Door Air Fryer," is used to open and close the large opening. However, the outer cover of these products is connected to the edges of the semi-open openings on both sides of the body, rather than to the corresponding sliding rails at the rear. Furthermore, the lack of handles on both sides of the pot or inner pot makes accessing the pot or inner pot inconvenient. Summary of the Invention

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide an air fryer outer cover protection structure that solves the technical problems of poor slide rail structure design, lack of both electric and manual operation modes, and inconvenient storage and retrieval of the inner pot in existing air fryer products. This objective is achieved through the following technical solution.

[0004] An air fryer outer cover protection structure is disclosed. The structure features a control panel on the top of the unit, and a large opening for accommodating the inner pot is located on one side of the unit between the control panel and the base. A key structural design element is a movable lifting mechanism located in the middle of the rear of the unit below the control panel. The sliding rails of this mechanism are symmetrically arranged on both sides of a raised cover in the middle of the rear of the unit. The circumference of the unit on both sides of the movable lifting mechanism forms a large, open opening. The rear opening of the outer cover, with a height greater than the height of the large opening at the unit, wedges into the sliding rails of the cover and slides up and down, while the outer cover fits within the outer diameter of the unit. The movable lifting mechanism employs a combination of a screw and a drive motor, facilitating both electric and manual raising and lowering of the outer cover.

[0005] The movable lifting mechanism includes a drive motor, a slide rail, and a screw. One end of the drive motor, which is located inside or outside the machine body, is connected to one end of the screw. The other end of the screw is connected to a connecting section integrally formed at the upper or lower rear end of the outer cover, which drives the outer cover to slide up and down. The two sides of the lower or upper opening at the rear end of the outer cover are wedged into the slide rail of the cover and slide up and down. The drive motor is correspondingly located at the bottom or top of the machine body and is connected to the control circuit board inside the machine body through wiring.

[0006] The bottom of the inner pot of the machine body is provided with a heat-insulating pad. A raised, circular trigger platform is located at the rear of the inner pot or the pad. When the inner pot is inserted into the large opening of the machine body through the pad and is in place, the trigger platform activates a corresponding microswitch or outer cover switch at the rear of the large opening. The microswitch or outer cover switch is connected to a drive motor via wiring. The shape of the trigger platform is not limited to a protrusion; it can be used to trigger the corresponding microswitch or outer switch. The above describes a structural embodiment where a microswitch acts as a positioning switch to monitor whether the inner pot is inserted, or a structural embodiment where the outer cover is triggered by an outer cover switch. Alternatively, the outer cover can be automatically opened and closed by triggering a corresponding push rod at the opening of the inner pot. According to the above structural design, the pad at the bottom of the inner pot can also be omitted.

[0007] The outer cover has symmetrical handle slots with bottom openings on both sides. When the outer cover slides down to close the large opening of the machine body through the drive motor and screw, the handle slots on both sides of the outer cover simultaneously pass through the rods of the handles on both sides of the pot.

[0008] The handles on both sides of the inner pot are respectively provided with baffles that are shaped to seal the handle grooves on both sides of the outer cover.

[0009] The handle is integrated with the inner pot via symmetrically arranged side lugs on both sides of the liner. Simultaneously, the liner and the baffles at the handle positions on both sides of the inner pot are integrally formed. This further improves the stability of the baffles and facilitates component assembly.

[0010] The handle is T-shaped, with the end of the handle connected to the inner pot increasing in size conically towards the inner pot. The other end of the handle is parallel to the bottom of the machine body and its length is greater than the width of the opening at the handle groove of the outer cover. The handle groove of the outer cover has an increasing triangular opening facing downwards.

[0011] The bottom of the liner has two symmetrical upper guide ribs on both sides, and the bottom of the corresponding base has two symmetrical lower guide ribs. The pot liner is placed into the large opening of the machine body by fitting the upper guide ribs of the liner and the lower guide ribs of the base together.

[0012] The rear cover of the machine body has symmetrical ventilation holes on both sides above it, or at least one ventilation hole is provided on one side of the machine body above the cover.

[0013] The heating element and hot air blades are sequentially arranged in a groove within the metal insulation layer above the pot opening on the top of the pot body. A cold air wheel is located inside the air guide shroud on top of the metal insulation layer. The air outlet on one side of the air guide shroud is connected to the ventilation hole of the unit body. The drive shaft of the fan motor on top of the air guide shroud is sequentially connected to the cold air wheel and the hot air blades. The control panel and heating element are connected to the control circuit board inside the unit body via wiring. The above is a structural embodiment of a double-blade design within the unit body above the pot body.

[0014] This utility model has a reasonable structural design, is easy to operate and use, and has various structural forms. In particular, the outer cover is convenient to open and close automatically through a motor and screw. It is suitable for use as a protective structure for air fryers and for structural improvements of similar products. Attached Figure Description

[0024] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-8As shown, the top of the body 1 of this structure is equipped with a control panel 3. Below the control panel, on one side of the body between the control panel and the base 10, there is a large opening for accommodating the inner pot 8. Below the control panel, in the middle of the rear of the body, there is a movable lifting mechanism. The slide rails 12 of the movable lifting mechanism are symmetrically arranged on both sides of the raised cover 14 in the middle of the rear of the body. The circumference of the body on both sides of the movable lifting mechanism is set as a large open opening. The rear opening of the outer cover 2, which is higher than the height of the large opening at the body, is wedged into the slide rail of the cover and slides up and down. At the same time, the outer cover fits the outer diameter of the body. The movable lifting mechanism includes a drive motor 11, a slide rail, and a screw 13. One end of the drive motor, which is located inside the body, is connected to one end of the screw. The other end of the screw is connected to the connecting corridor 201 integrally formed at the lower rear of the outer cover and drives the outer cover to slide up and down. The upper opening at the rear of the outer cover is wedged into the slide rail of the cover and slides up and down. The drive motor is correspondingly located at the top of the body and is connected to the control circuit board inside the body through wiring. Meanwhile, the bottom of the inner pot is provided with a heat insulation pad 15. The rear of the pad is provided with a raised, circular trigger platform. When the inner pot is placed into the large opening of the machine body through the pad and is in place, the trigger platform activates the corresponding micro switch 16 at the rear of the large opening of the machine body. The micro switch is connected to the drive motor through a circuit.

[0025] The outer cover has symmetrical handle grooves 202 with bottom openings on both sides. When the outer cover slides downwards to close the large opening of the machine body via a drive motor and screw, the handle grooves on both sides of the outer cover simultaneously pass through the rods of the handles 9 on both sides of the pot. The rods of the handles on both sides of the pot are respectively provided with baffles 17 that seal the shape of the handle grooves on both sides of the outer cover. The connection between the handle and the pot is integrated with the liner through symmetrically arranged side ears on both sides of the liner. At the same time, the liner and the baffles of the rods of the handles on both sides of the pot are integrally formed. The handle is T-shaped. The rod end of the handle connected to the pot increases in a conical shape towards the pot. The other end of the handle is parallel to the bottom of the machine body and its length is greater than the width of the opening of the handle groove of the outer cover. The handle groove of the outer cover has a downward-increasing triangular opening. Two upper guide ribs are symmetrically arranged on both sides of the bottom of the liner, and two lower guide ribs 1001 are symmetrically arranged at the bottom of the corresponding base. The pot is placed into the large opening of the machine body through the upper guide ribs of the liner and the lower guide ribs of the base.

[0026] The above-mentioned machine body has symmetrical ventilation holes on both sides of the upper part of the cover. The heating element 7 and hot air blade 6 are arranged in the groove of the metal heat insulation layer above the pot opening on the top of the pot body. The air guide shroud on the top of the metal heat insulation layer has a cold air wheel 5. The air outlet on one side of the air guide shroud is connected to the ventilation hole of the machine body. The drive shaft of the fan motor 4 on the top of the air guide shroud is connected to the cold air wheel and the hot air blade in sequence. The control panel and the heating element are connected to the control circuit board inside the machine body through wires.

[0027] When powered on, the outer cover rises, the inner pot is removed, and after adding ingredients, the inner pot is placed back into the machine. Press the function button to start the function, the outer cover lowers, and the machine begins operation. When the designated time has elapsed, the machine prompts you to toss the food, the outer cover rises, the inner pot is removed, and after tossing, it is placed back into the machine. The outer cover then lowers, cooking begins, and the outer cover automatically rises after cooking ends.

[0028] In summary, this structure features an outer cover around the air fryer to protect consumers from burns, meeting safety regulations. The outer cover is raised and lowered via a movable lifting mechanism, which can be operated electrically or manually, but primarily by electric automation. The internal structure contains a drive motor, screw, and slide rails. The drive motor is connected to the outer cover; when the motor rotates, it causes the outer cover to rise and fall.

[0029] The above description is intended to illustrate the technical means of this utility model and is not intended to limit the technical scope of this utility model. Any obvious improvements or substitutions made to this utility model by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of this utility model.
