This design facilitates the installation and removal of the fixed blade disc 4, and the fixed blade disc 4 is installed and removed in a horizontal direction, which can avoid the blade in the fixed blade disc 4 from cutting the user as much as possible. In addition, under the limiting effect of the limiting structure, the fixed blade disc 4 can be prevented from jumping up and down and being damaged during the operation of the food processor.

[0044] Example 1

[0045] Figures 1 to 7 Embodiment 1 of the present invention is shown. In this embodiment, the cooking support tray 3 is located inside the cooking cup 2. On the outer side wall of the cooking cup 2, there is a second mounting and dismounting opening 21 which is opposite to the first mounting and dismounting opening 311 and through which the fixed knife disk 4 can pass.

[0046] A cup cover 6 is installed at the cup mouth of the cooking cup 2. On the cup cover 6, there is a feeding groove 61 located above the fixed knife disk 4. A pushing rod 62 is movably installed at the feeding groove 61. The fixed knife disk 4 includes a knife frame 41 and a fixed knife assembly 42 fixed on the knife frame 41. The fixed knife assembly 42 is in a grid shape and is used for cutting food ingredients into dices.

[0047] An arc-shaped groove 43 is provided on the upper surface of the knife frame 41. There is a gap between the side wall 31 of the tray and the inner side surface of the cooking cup 2. The locking device includes a cover edge 63 provided at the lower end of the cup cover 6. When the cup cover 6 is closed on the cooking cup 2, the cover edge 63 passes through the gap and is inserted into the arc-shaped groove 43, and at this time, the fixed knife disk 4 can be locked.

[0048] As a further improvement scheme of this embodiment, the cover edge 63 is in a cylindrical shape. A rotary locking structure is provided between the inner side wall of the cooking cup 2 and the outer side wall of the cover edge 63, which can lock the cup cover 6 when the cup cover 6 rotates relative to the cooking cup 2. The cooking support tray 3 is circular and coaxial with the cover edge 63. On the inner side wall of the arc-shaped groove 43, there is a slope surface 101. The distance between the slope surface 101 and the axis of the cooking support tray 3 gradually increases from the starting end to the ending end of the slope surface 101. A pressing convex block 102 is provided on the inner side wall of the cover edge 63. When the cup cover 6 rotates to be locked on the cooking cup 2 through the rotary locking structure, the pressing convex block 102 rotates from the starting end to the ending end of the slope surface 101 relative to the fixed knife disk 4 to press the fixed knife disk 4 tightly. The rotary locking structure includes a locking block 202 provided on the inner side wall of the cooking cup 2, a vertical groove 631 provided on the outer side wall of the cover edge 63 and into which the locking block 202 can be inserted, and a circumferential groove 632 provided on the outer side wall of the cover edge 63 and into which the locking block 202 can be inserted. One end of the circumferential groove 632 is communicated with the vertical groove 631. When the cup cover 6 rotates, the locking block 202 is stuck into the circumferential groove 632 to lock the cup cover 6.

[0049] In this embodiment, the method for installing the fixed cutter disc 4 is as follows. First, pass the fixed cutter disc 4 through the second disassembly and assembly opening 21 and the first disassembly and assembly opening 311, so that the corresponding part on the fixed cutter disc 4 is installed in the blanking port. Then, install the cup lid 6 at the upper port of the cooking cup 2. When installing the cup lid 6, first align the vertical groove 631 on the lid edge 63 with the locking block 202 on the cooking cup 2, and then lower the cup lid 6 so that the locking block 202 enters the vertical groove 631. At this time, the lower end of the lid edge 63 is inserted into the arc groove 43. Then, rotate the cup lid 6 so that the locking block 202 is stuck in the circumferential groove 632, and the cup lid 6 can be locked. During the locking process of the cup lid 6, the top pressing convex block 102 rotates relative to the fixed cutter disc 4 from the starting end to the ending end of the climbing surface 101. Finally, it can achieve the purpose of locking both the cup lid 6 and the fixed cutter disc 4 while rotating and locking the cup lid 6, which serves two purposes and is very convenient.

[0050] The climbing surface 101 can be an inclined plane that gradually moves away from the axis of the cooking support disc 3; it can also be an involute-shaped arc surface that gradually moves away from the axis of the cooking support disc 3. Among them, the involute-shaped arc surface is the best.

[0051] In order to prevent the cup lid 6 from loosening relative to the cooking cup 2, the number of the locking blocks 202, the vertical grooves 631, and the circumferential grooves 632 is generally 3 - 5. The positions of the locking blocks 202, the vertical grooves 631, and the circumferential grooves 632 correspond to each other one by one. A convex part 634 that can clamp the locking block 202 is also provided on the inner side wall of the circumferential groove 632.

[0052] In this embodiment, the limiting structure includes an insertion hole 325 provided on the inner side wall of the blanking hole 321, an insertion block 405 at one end of the fixed cutter disc 4 and inserted into the insertion hole 325, and a support table 326 provided at the lower part of the blanking hole 321 and capable of supporting the lower surface of the fixed cutter disc 4. The number of the insertion holes 325 and the insertion blocks 405 is preferably 2. The two insertion blocks 405 are respectively located at the left and right parts of the front side surface of the fixed cutter disc 4.

[0053] The cooking cup 2 is installed on the upper surface of the main body 1. A cutter shaft 71 is rotatably installed in the middle of the cooking support disc 3. The rotary blade 5 is installed on the cutter shaft 71. The power device includes a motor provided inside the main body 1. A transmission shaft 72 capable of transmitting power between the motor and the cutter shaft 71 is rotatably installed in the cooking cup 2. A handle and a blanking groove 203 are provided on the cooking cup 2.

[0054] The dicing principle of this embodiment is as follows. When the motor rotates, the power can be transmitted to the rotary blade 5 through the transmission shaft 72 and the cutter shaft 71, driving the rotary blade 5 to rotate. At this time, the user adds the food ingredients into the feeding groove 61 and uses the pushing rod 62 to press the food ingredients downward. Under the combined action of the rotary blade 5 and the grid-shaped fixed cutter assembly 42, the food ingredients are cut into dices. The diced food ingredients fall into the cooking cup 2 and finally are discharged from the blanking groove 203.

[0055] Embodiment 2

[0056] Figure 8 Embodiment 2 of the present invention is shown. This embodiment has a similar structure to Embodiment 1, and the difference lies in that: the lid edge 63 is cylindrical, and a rotary locking structure is provided between the inner side wall of the cooking cup 2 and the outer side wall of the lid edge 63, which can lock the cup lid 6 when the cup lid 6 rotates relative to the cooking cup 2. The cooking support plate 3 is circular and coaxial with the lid edge 63. The inner side wall of the lid edge 63 has a ramp surface 101, and the distance between the ramp surface 101 and the axis of the cooking support plate 3 gradually increases from the starting end to the ending end of the ramp surface 101. A pressing protrusion 102 is provided on the inner side wall of the arc-shaped groove 43. When the cup lid 6 rotates and is locked on the cooking cup 2 through the rotary locking structure, the pressing protrusion 102 rotates relative to the cup lid 6 from the starting end to the ending end of the ramp surface 101 to tightly press the fixed knife plate 4.

[0057] In this embodiment, during the process of locking the cup lid 6, the pressing protrusion 102 rotates relative to the fixed knife plate 4 from the starting end to the ending end of the ramp surface 101, and it can also achieve locking the fixed knife plate 4 while rotating and locking the cup lid 6.
