Description

Technical Field

[0001] The invention relates to a filter structure and a food processor with the filter structure. Background Art

[0002] In order to grind beans and food into smaller pieces, existing food processors are generally equipped with a filter inside the food processor. During the grinding process, the food will repeatedly pass through the filter in the grinding barrel, so that the food can be ground into smaller pieces. The produced soy milk and juice will not have granular bean dregs or fruit residues, and the soy milk and juice will taste better, more delicate and smoother.

[0003] However, existing filters in food processors have the following defects: 1. The filter generally only has a disturbing effect, and can only block relatively large granular food from returning to the position of the crushing blade, so that the crushing blade can crush it again, and this cycle is repeated many times, resulting in high power consumption and energy consumption of the food processor; 2. The filter cannot effectively guide the flow direction of the fluid and increase the flow rate, resulting in turbulent fluid flow and too slow flow rate. It cannot drive relatively large granular food to be drained to the crushing blade, which prolongs the crushing time, resulting in high power consumption and high energy consumption of the food processor. Summary of the Invention

[0004] The object of the present invention is to overcome the shortcomings of the prior art and provide a filter structure with a simple structure suitable for various food chopping and processing machines, which can improve the chopping effect of the food chopper, greatly shorten the chopping time, reduce energy consumption, and make the chopping pulp and juice taste better, more delicate and smoother; and easy to assemble.

[0005] Another object of the present invention is to provide a food processor with better crushing effect, which can greatly shorten the crushing time, reduce energy consumption, and make the crushed pulp and juice taste better, finer, and smoother.

[0009] The filter structure as described above is characterized in that the first baffle and the second baffle are both flat plates, and the two transverse channels are both inclined upward transverse channels.

[0016] The present invention has the following beneficial effects: After being installed in the inner container of a food processor, the chopping blade extends into the lower chamber of the filter chamber, where the beans are chopped. During the rotation of the chopping blade, some beans are blocked by the flow blocking device and returned to the lower chamber to be chopped again by the chopping blade. The remaining beans flow with the water through the transverse channel into the upper chamber, and then enter the inner chamber through the filter holes in the upper chamber. This improves the chopping effect of the food processor, greatly shortens the chopping time, reduces energy consumption, and makes the slurry and juice produced by the chopping better, more delicate, and smoother in taste.

[0025] The present invention will be further described below in conjunction with the accompanying drawings:

[0026] A filter structure includes a cylindrical filter body 1, which is provided with a filter chamber 2 extending vertically therefrom. Filter holes 3 are provided in the upper portion of the filter body 1. A flow blocker 4 is provided within the filter body 1 to block the upward flow of food from the lower portion of the filter body. The flow blocker 4 divides the filter chamber 2 into an upper chamber 21 and a lower chamber 22. A transverse passage 5 is provided on the flow blocker 4, connecting the upper and lower chambers 21 and 22. When installed in a food processor, the present invention inserts a chopping blade into the lower chamber 22 of the filter chamber 2, chopping beans there. As the chopping blade rotates, some beans are blocked by the flow blocker 4 and returned to the lower chamber 22, where they are again chopped by the chopping blade. Others flow with the water through the transverse passage 5 into the upper chamber, and then into the inner chamber through the filter holes 3 in the upper chamber 21. This can make the food blender have better blending effect, greatly shorten the blending time, reduce energy consumption, and make the blended pulp and juice taste better, more delicate and smoother.

[0027] The flow-blocking device 4 of the present invention comprises at least a first flow-blocking plate 41 and a second flow-blocking plate 42. The outer surfaces of the first and second flow-blocking plates 41 and 42 are sealed against the inner wall of the filter chamber 2. The inner surfaces of the first and second flow-blocking plates 41 and 42 intersect, forming two transverse channels 5 between the first and second flow-blocking plates. During the rotation of the crushing blades, larger particles are blocked by the flow-blocking device 4 and returned to the lower chamber 22 for further crushing by the crushing blades. Other particles flow with the water through one of the transverse channels 5 into the upper chamber, then through the filter holes 3 of the upper chamber 21 and into the inner chamber. At this point, smaller particles flow through the other transverse channel 5 back into the lower chamber 22 and are again crushed by the crushing blades.
