Description

Technical Field

[0001] This invention belongs to the field of household kitchen appliance technology, and in particular relates to a detachable deep fryer with multiple height adjustment settings. Background Technology

[0002] Deep frying is a common cooking method widely used in homes and catering. Traditional deep fryers usually adopt an integrated structure design, with the pot body and heating element fixedly connected. The inner wall of the oil chamber is directly used as the heating area, which makes it easy for oil stains and food residue to adhere to the heating element and the dead corners of the inner wall of the pot after use. Cleaning requires repeated scraping with a brush, which is not only inefficient but also easily damages the surface coating of the heating element and shortens the service life of the equipment. In addition, in terms of cooking functions, most existing deep fryers use a fixed height or a single adjustable setting for the frying basket, which cannot flexibly adjust the oil immersion depth according to the characteristics of the ingredients (such as volume, density, and water content).

Detailed Implementation

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] Example 1: As Figures 1-20As shown, a detachable multi-level height adjustable fryer includes a stainless steel body 1, a clean inner liner 5, and a frying basket 21. The clean inner liner 5 is installed inside the stainless steel body 1 by a snap-fit ​​assembly. A temperature control assembly is installed on the side of the stainless steel body 1. The heating tube 14 of the temperature control assembly extends to the bottom of the clean inner liner 5. The frying basket 21 is snapped onto the level adjustment assembly provided on the side of the temperature control assembly. The working principle of the above technical solution is as follows: The stainless steel body 1, the cleaning inner pot 5, and the frying basket 21 are all made of stainless steel, which is not easy to rust or deform after long-term use. The cleaning inner pot 5 can be removed from the stainless steel body 1 for easy cleaning. The frying basket 21 is connected to the gear adjustment component by a snap-fit ​​method, so that the food carrying unit can stay in multiple positions such as above the oil surface, half-submerged, or fully submerged in the oil according to cooking needs. This structure realizes the zoned control of the frying process: when the frying basket 21 is in a high position, the food drains oil and controls the temperature; when it is in a middle position, it is half-submerged to achieve a crispy surface; and when it is in a low position, it is fully submerged to ensure uniform heating, thereby adapting to the cooking characteristics of different ingredients and improving the consistency of the finished product quality.

[0018] Example 2: Figures 1-20 As shown, a rubber ring 4 is provided between the stainless steel body 1 and the cleaning inner tank 5. Four supports 17 are threadedly connected to the lower end of the stainless steel body 1, and anti-slip pads are provided at the lower ends of the four supports 17. The working principle of the above technical solution is as follows: The rubber ring 4 is set at the contact interface between the stainless steel body 1 and the cleaning inner pot 5 to form a ring-shaped sealing structure, which effectively prevents the high-temperature oil from seeping out along the gap, while buffering the stress generated by the thermal expansion of the cleaning inner pot 5, avoiding abnormal noise or wear caused by direct friction between metal parts. The four supports 17 are installed at the bottom of the stainless steel body 1 by threaded connection. Users can independently adjust the height of each support 17 according to the flatness of the countertop to keep the pot body in a horizontal and stable state. The anti-slip pad at the lower end of the support 17 increases the friction coefficient with the contact surface, effectively suppressing the displacement of the equipment caused by vibration or external force during frying, ensuring cooking safety. This design takes into account both sealing reliability and placement adaptability, and is especially suitable for kitchen countertops of different materials and inclinations.

[0019] Example 3: Figures 1-20 As shown, the buckle assembly includes two triangular protrusions 2, which are respectively fixed on both sides of the stainless steel body 1. Handles 6 are fixed on both sides of the cleaning inner tank 5. An elastic block 3 is fixed at the lower end of the handle 6. An inverted triangular locking block is provided at the front end of the elastic block 3. The inverted triangular locking block is engaged and fixed with the triangular protrusion 2. The working principle of the above technical solution is as follows: The buckle assembly adopts a wedge-shaped engagement structure of triangular protrusion 2 and inverted triangular locking block to achieve quick installation and removal of the cleaning inner liner 5. During installation, the cleaning inner liner 5 is pressed vertically downwards, and the elastic block 3 is squeezed by the inner wall of the stainless steel body 1 to produce elastic deformation. After the inverted triangular locking block passes over the triangular protrusion 2, it automatically engages and locks under the action of elastic restoring force, forming a reliable mechanical anti-detachment connection. During disassembly, both hands simultaneously push the elastic blocks 3 on both sides outwards to make the inverted triangular locking block disengage from the limiting surface of the triangular protrusion 2, releasing the locked state. Then, the handle 6 can be lifted vertically to remove the cleaning inner liner 5 as a whole. This structure does not require tool assistance, greatly simplifying the cleaning process. The pre-tightening force design of the elastic block 3 ensures that the cleaning inner liner 5 will not loosen or fall off under the vibration of frying, taking into account both ease of operation and safety of use.

[0020] Example 4: Figures 1-20 As shown, the stainless steel body 1 has a long groove in the middle of its lower end. The cleaning inner tank 5 has an oil outlet pipe 7 fixed at its lower end. The lower end of the oil outlet pipe 7 passes through a round hole at the bottom of the stainless steel body 1 and is located in the long groove. A sealing valve 8 is provided in the oil outlet pipe 7. The stainless steel body 1 is slidably connected to the slide rod 9. The end of the slide rod 9 is sleeved on the outside of the sealing valve 8 switch. The slide rod 9 is fixedly connected to the fixed plate 11 and slidably connected to the support plate 12. A spring 10 is provided between the fixed plate 11 and the support plate 12. The working principle of the above technical solution is as follows: The oil outlet pipe 7 and the sealing valve 8 form a built-in oil drainage system, avoiding the risk of oil splashing and scalding caused by the traditional tilting oil changing method. When changing the oil, the user pushes the slide bar 9 to slide forward against the elastic force of the spring-10. The hexagonal hole at the end of the slide bar 9 is fitted into the sealing valve 8 switch. Rotating the slide bar 9 drives the valve core to rotate and open the flow channel. The waste oil in the cleaning tank 5 is introduced into the oil collection box at the bottom of the stainless steel body 1 through the oil outlet pipe 7. After the operation is completed, the slide bar 9 is released, and it automatically resets and disengages from the valve switch under the restoring force of the spring-10 to prevent accidental closure. This design supports two oil changing modes: when the cleaning tank 5 is in place, the oil can be changed remotely by controlling the slide bar 9, which is suitable for daily small-volume oil changes; or the cleaning tank 5 can be removed first and then the valve can be opened manually to completely drain the oil, which is suitable for deep cleaning. The long groove structure connects to the oil box to form a semi-enclosed storage space, which prevents the oil box from accidentally slipping out and improves the cleanliness and safety of the operation.

[0021] Example 5: Figures 1-20 As shown, the temperature control component includes a controller 13, which is installed inside the housing 15. The heating tube 14 is connected to the controller 13. The housing 15 is rotatably connected to one end of the transparent protective cover 16. The other end of the transparent protective cover 16 and the upper end of the housing 15 are both provided with magnets. The lower end of the housing 15 is provided with a limiting groove. The upper end of the screw 19 slides in the limiting groove. The screw 19 slides into the notch provided on the side of the stainless steel body 1. The screw 19 is threadedly connected to the locking nut 20. The locking nut 20 abuts against the stainless steel body 1. The cleaning inner liner 5 is provided with a partition 18, which is located above the heating tube 14. The working principle of the above technical solution is as follows: The transparent protective cover 16 is closed in front of the controller 13 panel by magnetic adsorption, forming a physical isolation barrier, which effectively prevents oil droplets splashing during frying from contaminating the control element, while maintaining the visibility of the operation interface, making it convenient for users to monitor temperature and time parameters in real time. The temperature control component adopts a detachable installation: After loosening the locking nut 20, the screw 19 slides horizontally along the lower end limit groove of the housing 15 and disengages from the notch of the stainless steel body 1. The controller 13, heating tube 14 and housing 15 can then be taken out as a whole module, which is convenient for thoroughly cleaning the carbon buildup on the surface of the heating tube 14 or replacing faulty components. When reinstalling, align the housing 15 with the installation position of the stainless steel body 1, slide the screw 19 into the notch and tighten the locking nut 20. The threaded locking force firmly presses the module against the side wall of the stainless steel body 1. The partition 18 is set above the heating tube 14 to prevent the frying basket 21 from directly contacting the heating tube 14, extending the service life of the heating tube 14 and ensuring uniform heat conduction.

[0022] Example 6: Figures 1-20 As shown, the frying basket 21 includes a frying basket body. One end of the frying basket body is rotatably connected to the handle 22. The other end of the frying basket body is provided with a hook 23. The lower end of the hook 23 is provided with a top block 24. A connecting post 25 is fixed inside the top block 24. The top block 24 abuts against the gear adjustment component. The hook 23 and the connecting post 25 are both engaged and connected with the gear adjustment component. The working principle of the above technical solution is as follows: The main body of the frying basket 21 and the handle 22 adopt a rotating connection structure. The handle 22 can be flipped inward and stored below the plane of the frying basket 21, significantly reducing the overall height of the equipment, making it easy to store in a cabinet or for packaging and transportation, and avoiding damage from collisions of protruding parts. The hook 23 and the top block 24 form a dual positioning structure: the hook 23, as the main load-bearing point, is hooked onto the limiting post 48 of the gear adjustment component, bearing the weight load of the frying basket 21 and the food; the top block 24, as an auxiliary support surface, abuts against the outer plate 32 of the adjustment component, limiting the swing amplitude of the frying basket 21 under the buoyancy of oil or swaying action, ensuring the stability of the frying basket 21. The connecting post 25 and the bent plate 42 form an elastic locking pair. During the loading of the frying basket 21, the connecting post 25 is automatically locked by the torsion spring preload of the bent plate 42, preventing the frying basket 21 from accidentally detaching during lifting and lowering. This structure realizes a triple safety mechanism of "one hook, one abutment, and one lock" for loading the frying basket 21, improving operational reliability.

[0023] Example 7: Figures 1-20As shown, the gear adjustment assembly includes a motor 26, which is fixed inside the housing 15. The output end of the motor 26 is connected to a bevel gear 1, which meshes with a bevel gear 2. The bevel gear 2 is fixed to the end of a rotating shaft 27, which is rotatably connected to the housing 15. Two gears 28 are fixed on the rotating shaft 27, and the two gears 28 mesh with two racks 29 respectively. Both racks 29 are slidably connected to a bracket 30, which is fixed to the outer wall of the housing 15 by screws. An inner plate 31 is fixed between the two racks 29, and the inner plate 31 is rotatably connected to a rotating column 33. An outer plate 32 is fixed to one end of the rotating column 33, and a rocker arm 34 is fixed to the other end. The rocker arm 34 has a vertical groove inside. The inner plate 31 is fixedly connected to a motor 2 36, and the output end of the motor 2 36 is connected to a rotating rod 35. A protrusion is provided at the end of the rotating rod 35, and the protrusion slides in the vertical groove. The outer plate 32 is fixedly connected to the limiting post 48, the hook 23 is snapped into the limiting post 48, the outer plate 32 is rotatably connected to both ends of the bending plate 42, the bending plate 42 is snapped into the connecting post 25, the front end of the top block 24 abuts against the outer plate 32, the outer plate 32 and the bending plate 42 are rotatably connected and provided with a torsion spring, the outer plate 32 is fixedly connected to the limiting plate 43, the limiting plate 43 is slidably connected to the pressure plate 44, a spring 45 is provided between the limiting plate 43 and the pressure plate 44, the pressure plate 44 is rotatably connected to the pulley 46, and the pulley 46 rotates in the sliding groove 47 provided on the housing 15; Both the inner plate 31 and the outer plate 32 are slidably connected with plug-in posts 37. A second spring 39 is provided between the inner plate 31 and the second support plate 38 provided on the plug-in post 37. An inclined groove 40 is provided in the plug-in post 37. A limit rod 41 is fixed on the housing 15. The limit rod 41 slides in the inclined groove 40. The working principle of the above technical solution is as follows: the hook 23 of the blasting basket 21 is hooked onto the limiting post 48 fixed on the outer plate 32, while the front end of the top block 24 abuts against the surface of the outer plate 32 to form an auxiliary support surface; the blasting basket 21 is lowered further, and its connecting post 25 is pressed down into the front opening of the bent plate 42, forcing the bent plate 42 to overcome the preload of the torsion spring and rotate slightly outward; when the blasting basket 21 is completely flattened, the connecting post 25 slides into the locking position of the bent plate 42, and under the action of the torsion spring restoring force, the bent plate 42 automatically rotates back to lock the connecting post 25, forming a triple positioning structure of "hook 23 main load bearing + top block 24 anti-sway + bent plate 42 anti-disengagement", ensuring that the blasting basket 21 maintains a stable posture during oil sloshing or lifting; The motor 26 is started, and its output drives the bevel gear 1 to rotate. The horizontal rotational motion is converted into the vertical axial rotation of the shaft 27 through the meshing transmission of the bevel gear 2. The double gears 28 on the shaft 27 synchronously drive the racks 29 on both sides to move smoothly down along the vertical guide rail of the bracket 30. The racks 29 drive the inner plate 31 and the outer plate 32 to descend as a whole. The outer plate 32, through the connection between the limiting post 48 and the hook 23, pulls the frying basket 21 to move down synchronously and immerse it in the oil in the clean inner liner 5, so that the food is heated and fried evenly. After frying, motor 26 reverses and drives rack 29 to move upward, causing frying basket 21 to detach from the oil surface for oil draining. When inner plate 31 and outer plate 32 continue to rise to the preset high position, pulley 46 fixed to pressure plate 44 slides along the groove 47 on housing 15 to the top and disengages from the limiting track. Under the thrust of spring 3 45, pressure plate 44 moves forward rapidly, and its front end presses against the upper end of bending plate 42 to form a mechanical lock, preventing bending plate 42 from disengaging from connecting column 25 due to inertial rotation during the flipping process, thus ensuring the connection reliability of frying basket 21 under subsequent flipping conditions. During the upward movement of the inner plate 31 and the outer plate 32, the inclined groove 40 and the limiting rod 41 slide, which drives the insertion post 37 to move, which in turn causes the spring 39 to be stretched. The front end of the insertion post 37 separates from the outer plate 32, ensuring that the outer plate 32 can rotate subsequently. After the high-position locking is completed, the second motor 36 drives the first rotating rod 35 to rotate. The eccentric protrusion at its end slides in the vertical groove of the swing rod 34, converting the rotational motion into the reciprocating swing of the swing rod 34. The swing rod 34 drives the outer plate 32 to swing at a small angle periodically through the rotating column 33, thereby driving the frying basket 21 to swing back and forth synchronously, so that the food inside can be automatically turned over, avoiding heat loss, oil fume overflow and scalding risk caused by manual opening of the lid, while improving the evenness of food heating. After the flipping is completed, motor 26 starts again to drive the inner plate 31 and outer plate 32 to move down, the inclined groove 40 separates from the limiting rod 41, and under the elastic force of spring 39, the front end of the plug-in post 37 is driven to re-insert into the locking hole of the outer plate 32, and the inner plate 31 and outer plate 32 are rigidly fixed together. This locking mechanism effectively prevents food from spilling due to the free rotation of the outer plate 32 during the re-immersion of the frying basket 21 in the oil, and ensures that the re-frying process is stable and controllable.

[0024] Example 8: As Figures 1-20 As shown, a bracket 49 is fixed on the housing 15, a limit block 50 is fixed on the bracket 49, one end of the bracket 49 is rotatably connected to a rotating rod 51, the other end of the rotating rod 51 is fixed to a limit post 53, and the rotating rod 51 is fixedly connected to the upper plate 52. The working principle of the above technical solution: The bracket 2 49 and the rotating rod 2 51 constitute a manual / automatic mode switching mechanism. In automatic mode, the rotating rod 2 51 rotates 180 degrees to retract the limiting post 2 53 and the upper plate 52 to the side of the housing 15, avoiding interference with the normal lifting stroke of the rack 29. In manual mode, the rotating rod 2 51 is rotated in the opposite direction to extend the limiting post 2 53 and the upper plate 52 to the working position. The user lifts the basket 21 to disengage the hook 23 from the limiting post 1 48 of the automatic adjustment mechanism, and continues to lift it until the hook 23 is hooked onto the limiting post 2 58. 3. At the same time, the top block 24 abuts against the upper plate 52 to form support, realizing the high-position suspension of the frying basket 21 for oil draining. This structure allows users to manually complete the basket lifting and oil draining operation without disassembling the frying basket 21 when the equipment is powered off, the motor fails, or when it is necessary to temporarily check the food status. The limiting block 50 mechanically limits the rotation angle of the rotating rod 51, ensuring that the manual / automatic modes are switched in place and the status is clear, avoiding misoperation caused by unclear part positions. This design enhances the fault tolerance and flexibility of the equipment, meeting the needs of diverse cooking scenarios.
