Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food processors, in particular to a hand-automatic integrated oil circuit system and a food processor thereof. BACKGROUND

[0002] When the food processor is working, the motor drives the stirring knife to rotate at high speed to achieve powerful chopping. In order to facilitate the taking and placing of the stirring cup, the transmission joint is designed as a detachable structure. This structure itself has a gap, and the coaxiality of the motor output shaft and the stirring knife shaft is not good. Under high-speed operation, these factors together cause severe vibration and noise at the joint, and cause collision between parts, further amplifying the noise. Therefore, some food processors on the market currently add a soundproof cover to block the transmission of noise, thereby effectively reducing the working volume of the whole machine.

[0003] Although the existing food processor adds a soundproof cover, it can effectively reduce the working noise, but its most important disadvantage is that it significantly increases the complexity of operation. Specifically, as an additional component, the soundproof cover needs to be installed and disassembled by the user before and after each use of the food processor. This will interrupt the continuity of the meal preparation process, especially when additional ingredients need to be added or the food status needs to be observed, the soundproof cover must be removed first, and then re-covered after the operation is completed. The whole process is cumbersome and inconvenient.

[0046] This food processor includes a main unit 29, a soundproof cover 30, and a manual / automatic integrated hydraulic system. The soundproof cover 30 is rotatably mounted on the main unit 29. The extended end 7 of the hydraulic cylinder 3 is rotatably connected to the main unit 29, and the piston rod 10 of the hydraulic cylinder 3 is rotatably connected to the soundproof cover 30. When the hydraulic cylinder 3 drives the soundproof cover 30 to open and close, it swings on the main unit 29. When the piston rod 10 of the hydraulic cylinder 3 extends, it drives the soundproof cover 30 to rotate and open on the main unit 29. When the piston rod 10 of the hydraulic cylinder 3 retracts, it drives the soundproof cover 30 to rotate and close on the main unit 29. The manual / automatic integrated hydraulic system realizes the automatic opening and closing and manual adjustment of the soundproof cover 30, replacing the traditional extra steps of repeated installation and disassembly.

[0047] The manual / automatic hydraulic system drives the opening and closing of the food processor's soundproof cover 30, and features both automatic and manual modes. 1. No power / standby mode: Manual operation mode When the food processor is in a state of no power or not working, the system preset valve core 9 is held in the third position C. At this time, the extension end 7 of the oil cylinder 3 and the retraction end 8 of the oil cylinder 3 are directly connected through the third switching channel 13. The oil cylinder 3 is depressurized and is in a free floating state. Therefore, the user can easily open and close the soundproof cover 30 manually to operate the processor or take out food.

[0048] 2. Power-on / Operating Status: Automatic Control Mode When the food processor is powered on and started, the system enters the automatic control mode, and the motor 4 precisely drives the valve core 9 to switch the oil circuit; Opening the soundproof cover 30: After the user issues the open command, the motor 4 first drives the valve core 9 to switch to the first position A. Then, the integrated oil pump 1 starts to supply oil. The hydraulic oil flows into the extension end 7 of the cylinder 3 through the "oil inlet 20", pushing the piston rod 10 of the cylinder 3 to extend, thereby opening the soundproof cover 30. At the same time, the oil in the "return end 8 of the cylinder 3" returns smoothly to the integrated oil pump 1 through the "return port 23", forming a cycle.

[0049] Closing the soundproof cover 30: After the user issues a closing command, the motor 4 drives the valve core 9 to switch to the second position B. The hydraulic oil supplied by the integrated oil pump 1 flows into the "return end 8 of the oil cylinder" through the "oil inlet 20", pulling the piston rod 10 of the oil cylinder 3 to retract, thereby closing the soundproof cover 30. During this process, the oil at the "extension end 7 of the oil cylinder 3" is pushed back to the integrated oil pump 1 through the "return port 23".

A rotating shaft 42 is provided on the upper shell 41, and a rotating hole 43 is provided on the soundproof cover 30. The rotating shaft 42 is rotatably connected to the rotating hole 43, so that the soundproof cover 30 is rotatably opened and closed on the main unit 29. When the piston rod 10 of the hydraulic cylinder 3 extends, it drives the soundproof cover 30 to rotate upward, so that an opening is formed between the soundproof cover 30 and the upper shell 41 (e.g., ...). Figure 13 As shown), when the piston rod 10 of the hydraulic cylinder 3 retracts, it drives the soundproof cover 30 to rotate downwards, so that the soundproof cover 30 and the upper shell 41 form a closed cover (as shown). Figure 14 (As shown); the rotating shaft 42 is the pivot point, and the soundproof cover 30 is sealed by screwing the upper shell 41 together with the pivot point.

[0051] The integrated oil pump 1, reversing valve 2 and motor 4 are installed in the base 40. The base 40 is equipped with a control circuit board. The control circuit board is electrically connected to the motor 4 and the integrated oil pump 1. The control circuit board controls the motor 4 to precisely drive the valve core 9 to switch the oil circuit.

[0052] The top of the base 40 is provided with a third through hole 44. The oil pipe 37 leading out from the extension end 7 of the oil cylinder 3 extends into the interior of the base 40 through the third through hole 44 so as to connect to the oil cylinder extension connection port 26. The oil pipe 37 leading out from the retraction end 8 of the oil cylinder 3 extends into the interior of the base 40 through the third through hole 44 so as to connect to the oil cylinder retraction connection port 31.

[0053] An end cap 45 is installed on the inner side of the upper shell 41. A first rotating shaft 46 is provided between the end cap 45 and the upper shell 41. A first rotating hole 47 is provided on the extended end 7 of the oil cylinder 3. The first rotating shaft 46 is rotatably connected to the first rotating hole 47 so that the extended end 7 of the oil cylinder 3 is rotatably connected to the main unit 29. A second rotating shaft 48 is provided on the soundproof cover 30. A second rotating hole 49 is provided on one end of the piston rod 10 of the oil cylinder 3. The second rotating shaft 48 is rotatably connected to the second rotating hole 49 so that the piston rod 10 of the oil cylinder 3 is rotatably connected to the soundproof cover 30.
