[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model proposes a deep fryer with lifting and filtering oil function, including a base plate 1, a frying box 4 and a filter frame 6. The front end of the frying box 4 is provided with a control box. Vertical rods 2 are vertically arranged at the four corners of the upper end of the base plate 1. Positioning rings 5 ​​are fixedly arranged at the four corners of the top of the frying box 4. The positioning rings 5 ​​are penetrated by the vertical rods 2 and are slidably connected to the vertical rods 2. The filter frame 6 is inserted into the frying box 4 and is located above the frying box 4. Positioning sleeves 7 are fixedly arranged at the four corners of the top of the filter frame 6. The lower end of the positioning sleeves 7 is provided with positioning grooves. The top of the vertical rods 2 is inserted into the positioning grooves.

[0025] A positioning plate 8 is fixedly installed at the front end of the base plate 1, a fixing box 11 is fixedly installed at the upper end of the base plate 1, a cylindrical tube 9 is fixedly installed at the lower end of the frying box 4, a threaded rod 10 is vertically rotatably installed at the top of the fixing box 11, the threaded rod 10 is inserted into the cylindrical tube 9 and threadedly connected to the cylindrical tube 9, a worm gear 17 is fixedly installed at the bottom end of the threaded rod 10, a rotating shaft 12 is horizontally rotatably installed at the bottom of the fixing box 11, the front end of the rotating shaft 12 passes through the positioning plate 8 and is rotatably connected to the positioning plate 8, a driven sprocket 13 is fixedly installed at the front end of the rotating shaft 12, and a worm 18 is fixedly installed at the rear end of the rotating shaft 12, the worm 18 meshes with the worm gear 17;

[0026] The top of the positioning plate 8 is rotatably provided with a positioning shaft, and the front end of the positioning shaft is fixedly provided with a drive sprocket 14. The drive sprocket 14 and the driven sprocket 13 are connected by a chain 15.

[0027] Frying preparation: The temperature of the cooking oil in the frying box 4 is set and adjusted by the control box at the front end of the frying box 4. After the oil temperature reaches the required state, the food to be fried is placed in the filter frame 6. Since the filter frame 6 is positioned by the positioning groove of the positioning sleeve 7 and the top of the vertical rod 2, it can ensure that the food is stably in the oil bath area of ​​the frying box 4. Then the frying process is started.

[0028] After frying, lift the pan to drain the oil:

[0029] A limiting plate 3 is fixedly installed at the bottom of the vertical rod 2. A spring 19 is provided at the upper end of the limiting plate 3 and is penetrated by the vertical rod 2. The top end of the spring 19 contacts the lower end of the positioning ring 5. The bottom end of the spring 19 is fixed to the upper end of the limiting plate 3, and the top end of the spring 19 is fixed to the lower end of the positioning ring 5.

[0030] Two handles are symmetrically arranged at the upper end of the filter frame 6.

[0031] The front end of the drive sprocket 14 is provided with a rocker arm 16, and the positioning shaft and the rotating shaft 12 are rotatably connected to the positioning plate 8 through bearings.

[0032] When the food is fried and needs to be drained, the operator turns the rocker arm 16 at the front end of the drive sprocket 14, which drives the positioning shaft and the drive sprocket 14 to rotate synchronously.

[0033] The drive sprocket 14 drives the driven sprocket 13 to rotate via the chain 15, thereby causing the shaft 12 to rotate accordingly;

[0034] The worm 18 at the rear end of the rotating shaft 12 rotates synchronously. Because the worm 18 meshes with the worm wheel 17 at the bottom of the threaded rod 10, the worm 18 drives the worm wheel 17 and the threaded rod 10 to rotate. Since the worm 18 can only drive the worm wheel 17 to rotate, and the worm wheel 17 cannot drive the worm 18 to rotate, the stability of the frying box 4 is ensured during use.

[0035] The threaded rod 10 is threadedly connected to the cylindrical tube 9. When the threaded rod 10 rotates, it drives the cylindrical tube 9 and the frying box 4 fixed thereto to descend vertically. During this process, the positioning ring 5 at the top of the frying box 4 slides down along the vertical rod 2 and compresses the spring 19 at the upper end of the limiting plate 3.

[0036] As the frying tank 4 descends, the filter frame 6, which was originally inside the frying tank 4, is gradually exposed above the oil surface and begins to drain the oil naturally.

[0037] Food removal and equipment reset: After the oil is drained, the operator removes the filter frame 6 from the fryer 4 using the handle at the top of the filter frame 6 and pours the food inside into the designated container.

[0038] Then, the rocker arm 16 is rotated in the opposite direction, driving the sprocket 14 to drive the driven sprocket 13, the shaft 12 and the worm gear 18 to rotate in the opposite direction via the chain 15. The worm gear 17 then drives the threaded rod 10 to rotate in the opposite direction, and the cylindrical tube 9 drives the frying box 4 to rise in the vertical direction.

[0039] At this time, the spring 19 at the upper end of the limit plate 3 releases its elastic force, offsetting part of the weight of the frying box 4. The auxiliary positioning ring 5 slides upward along the vertical rod 2 until the frying box 4 rises back to its initial position. The filter frame 6 is reinserted into the frying box 4 and positioned with the vertical rod 2 through the positioning sleeve 7. The equipment returns to its initial state and waits for the next use.

[0040] The top end of the cylindrical tube 9 is provided with a limiting plate, which is fixed to the lower end of the frying box 4 by screws.

[0041] The spring 19 on the bottom limiting plate 3 of the vertical rod 2 cooperates with the positioning ring 5 to offset part of the weight of the fryer box 4 when it rises, reducing the force required to turn the rocker arm 16 and reducing the labor intensity of the operator; and the positioning shaft, rotating shaft 12 and positioning plate 8 are all connected by bearings, which greatly reduces the rotational friction resistance, making the rocker arm 16 rotate more smoothly and the operation easier.

[0042] The handle at the top of the filter frame 6 makes it easy to quickly pick up and put in ingredients. Its top positioning sleeve 7 fits precisely with the top of the vertical rod 2 through the positioning groove, ensuring that it can maintain a stable position every time it is put into the frying box 4, avoiding the food from shifting and affecting the frying effect, without the need for repeated adjustments.

[0043] The frying box 4 slides with the vertical rod 2 on the bottom plate 1 through the positioning rings 5 ​​at the four corners of the top. During the lifting process, it always moves along the direction of the vertical rod 2 to avoid tilting or shaking, ensuring that the filter frame 6 is stable when draining oil and preventing food from spilling. At the same time, the threaded connection between the threaded rod 10 and the cylindrical tube 9 transmits power stably. With the deceleration transmission of the worm gear 18 and worm wheel 17, the stability of the lifting process is further improved.

[0044] The limiting plate is fixed to the lower end of the frying box 4 with screws, which is tight and easy to disassemble and maintain later. The worm gear 17 and the threaded rod 10, and the worm 18 and the rotating shaft 12 are all fixedly connected, so there is no loosening during the transmission process, which reduces the wear of parts. The use of bearings not only reduces rotational friction, but also avoids wear caused by direct contact of parts, thus extending the service life of the entire transmission mechanism.

[0045] The control box at the front end of the frying box 4 can precisely regulate the oil temperature inside the box, ensuring stable temperature during the frying process and preventing the food from being undercooked or overcooked due to oil temperature fluctuations, thus improving the frying quality. In addition, the design of the filter frame 6 not only facilitates the concentrated frying of food, but also allows for rapid oil drainage after lifting and lowering, reducing excess oil on the surface of the food, meeting the needs of healthy eating, and is suitable for various food processing scenarios such as restaurants and food processing plants.

[0046] Spring type 19: "Cylindrical helical compression spring" is preferred;

[0047] Reasons for selection: This type of spring 19 has a simple structure and mature processing, can stably withstand axial compression load, and the compression stroke is controllable, perfectly matching the linear motion requirements of "compression when the frying box 4 descends and rebound when it rises"; compared with tension springs or torsion springs, it is more in line with the "sleeving-compression" installation form on the vertical rod 2, and is not easy to fall off or get stuck.
