Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a soy milk maker. Background Technology

[0002] Existing soy milk makers typically use a single grinding method, which involves cutting and grinding the soybeans using high-speed rotating blades. This method works well when processing larger soybean particles, but when the soybeans are ground into smaller particles, the efficiency of this single cutting and grinding method decreases significantly, making it difficult to obtain smooth, residue-free soy milk.

[0003] Meanwhile, the blending blades of existing soymilk makers are prone to wear after prolonged use, affecting the grinding effect. In addition, for dry soybeans that have not been soaked, the initial cutting force of the single cutting and grinding method is relatively large, which accelerates the wear of the blending blades. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a soymilk maker that can reduce the wear rate of the blending blade and ensure the blending effect, in light of the current state of the technology.

[0005] The second technical problem to be solved by this utility model is to provide a soy milk maker that can improve the pulverizing effect and make the soy milk more delicate.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a soymilk maker, comprising:

[0007] The machine casing has a cell-breaking chamber inside, and a feeding port at the top of the cell-breaking chamber for soybeans to enter.

[0008] A cell-breaking blade is located inside the cell-breaking chamber and can rotate around a first axis extending vertically under the drive of a drive mechanism to cut the soybean material inside the cell-breaking chamber. The direction around the first axis is referred to as the first circumferential direction.

[0009] Its characteristic is that it also includes:

[0010] A grinding ring and a grinding disc that cooperate with the grinding ring are disposed inside the crushing chamber and above the crushing blade. The grinding ring is disposed on the inner wall surface of the crushing chamber along the first circumferential direction. The grinding disc is placed horizontally around the inner circumference of the grinding ring to divide the crushing chamber into an upper chamber located above the grinding disc and having the aforementioned feeding port, and a lower chamber located below the grinding disc and having the aforementioned crushing blade. The grinding disc can rotate circumferentially relative to the grinding ring under the drive of the driving mechanism to grind the soybeans entering from the feeding port. At the same time, a through hole is provided between the grinding disc and / or the grinding ring and / or the grinding disc and the grinding ring for the ground soybeans to pass through. The through hole connects the upper chamber and the lower chamber.

[0011] The grinding ring and the grinding disc that work with it perform initial grinding of the soybeans entering through the feed inlet. After grinding, the smaller soybean particles enter the lower chamber through the through-hole, where they are further broken down by the cutting action of the crushing blades. At this stage, the smaller particle size reduces the wear rate on the crushing blades. Furthermore, the grinding action of the grinding disc and ring, combined with the cutting action of the crushing blades, ensures effective cell wall breaking. Simultaneously, the grinding disc design above the crushing blades reduces the volume of the lower chamber where the blades are located, lowering the liquid flow height during crushing and further facilitating cutting and crushing.

[0012] Preferably, the upper surface of the grinding disc is provided with an impact hammer. As the grinding disc rotates, the impact hammer can impact and crush the soybeans.

[0013] Preferably, the grinding ring has a vertically extending first ring wall and a second ring wall extending inward from the lower periphery of the first ring wall. The grinding ring is provided with a plurality of L-shaped holes at intervals along the first circumferential direction as the aforementioned through holes. The vertical part of each L-shaped hole is located on the lower side of the first ring wall, and the horizontal part is located on the second ring wall and penetrates the inner periphery of the second ring wall.

[0014] The grinding disc is located on the second annular wall, and the edge of the grinding disc is spaced apart from the first annular wall.

[0015] To facilitate the passage of small, ground soybean particles, the grinding disc preferably has multiple perforations extending through the disc's thickness, serving as the aforementioned through-holes. Preferably, the diameter of these perforations is 2 millimeters.

[0016] Furthermore, multiple filter holes arranged radially at intervals are grouped together, with at least two groups arranged at intervals along the first circumferential direction.

[0017] Preferably, the depth dimension of the upper chamber in the vertical direction is greater than the depth dimension of the lower chamber in the vertical direction.

[0018] When a soymilk maker is working, the minimum amount of water inside usually covers the grinding disc. In this invention, the upper chamber is designed to be deeper than the lower chamber. This design has two advantages: 1. It allows the water to cover the grinding disc even with a small amount of water; 2. It further reduces the fluid height in the lower chamber during cutting, making it more conducive to the cutting and crushing of the blending blade.

[0019] Furthermore, the shaping blade is positioned relatively close to the bottom wall of the lower chamber and relatively far from the grinding disc. After being ground by the grinding disc, the small bean particles settle downwards under their own gravity. The design of the shaping blade's position in this invention increases the probability of the blade cutting the bean particles.

[0020] In the above scheme, preferably, the driving mechanism is a motor, the motor shaft extends upward and is connected to the wall-breaking blade, and the upper end of the motor shaft is connected to the grinding disc through a connecting shaft, which is arranged coaxially with the motor shaft.

[0021] Preferably, the side wall of the upper chamber is provided with an air blowing hole to allow external air to enter the upper chamber. The external air source can be compressed air, or gases such as nitrogen or carbon dioxide. After the external air enters the upper chamber through the air blowing hole, it promotes the flow of water within the upper chamber, improving the grinding effect.

[0022] Preferably, the bottom of the lower chamber is provided with a discharge port that can be opened or closed. During the operation of the soy milk maker, the discharge port is always in a closed state, and it opens after the soy milk is made.

[0023] To further address the second technical problem mentioned above, preferably, the wall-breaking blade includes:

[0024] The tool holder rotates around the aforementioned first axis at the center of the tool holder under the drive of the drive mechanism;

[0025] At least two blades are spaced apart around the blade holder in the first circumferential direction, and the first end of each blade is connected to the blade holder. The second end of each blade is a free end extending outward toward the side wall of the corresponding lower chamber, and each blade is a bendable steel wire.

[0026] When the blending blades rotate at high speed, the first end of each blade experiences less centrifugal force, while the second end experiences greater centrifugal force. This causes the flexible blade body to exhibit a certain degree of curvature. The diameter of the circle formed by the second end of each blade can automatically adjust according to the magnitude of the centrifugal force, allowing the blades to automatically adjust the sweeping cross-section. This avoids insufficient blending and the formation of lumps, as seen in existing technologies, thus improving the final pulverization efficiency of food. Simultaneously, the flexible structure of the blade body reduces the possibility of blade jamming. Furthermore, compared to traditional rigid blades, the flexible blade body reduces cutting noise, solving the problem of excessive operating noise in existing technologies and improving the user experience.

[0027] Compared with existing technologies, the advantages of this invention are as follows: The design of the grinding ring and the grinding disc that cooperates with the grinding ring can perform preliminary grinding on the soybeans entering from the feeding port. After grinding, the soybeans with smaller particle sizes enter the lower chamber through the through hole, where they are further broken down by the cutting action of the wall-breaking blade. At this time, because the soybean particles are smaller, the wear rate on the wall-breaking blade is reduced. Furthermore, the grinding action of the grinding disc and the grinding ring, as well as the cutting action of the wall-breaking blade, ensures the wall-breaking effect of the soybeans. At the same time, the design of the grinding disc above the wall-breaking blade makes the volume of the lower chamber where the wall-breaking blade is located smaller, which reduces the liquid flow height of the wall-breaking blade during wall breaking, making it more conducive to the cutting and crushing of the wall-breaking blade.

[0032] Figure 5 for Figure 2 Enlarged view of part A in the middle. Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-5 As shown, this is a preferred embodiment of a soymilk maker according to the present invention. The soymilk maker includes a shell 1, a wall-breaking blade 2, a drive mechanism 3, a grinding ring 4, and a grinding disc 5.

[0035] The machine casing 1 has a crushing chamber inside, with a feeding port 10 at the top for soybeans to enter, and a slurry outlet 121 at the bottom that can be opened or closed (the switch valve for opening and closing the slurry outlet 121 is designed according to existing technology and will not be described in detail here) for soybean slurry to be discharged. At the same time, the machine casing 1 is provided with a top cover 13 that can open or close the feeding port 10.

[0036] The blending blade 2 is located in the bottom space of the blending chamber and can rotate around the vertically extending first axis 30 under the drive of the driving mechanism 3 to cut the soybeans in the blending chamber. The direction around the first axis 30 is referred to as the first circumferential direction. Specifically, the driving mechanism 3 is a motor. The motor shaft extends upward and passes through the bottom wall of the blending chamber into the bottom space of the blending chamber. The central axis of the motor shaft is the aforementioned first axis 30. The blending blade 2 includes a blade holder 20 and four blades 21. The center of the blade holder 20 is connected to the motor shaft so that it can rotate around the first axis 30 under the drive of the motor shaft. The four blades 21 are evenly spaced around the blade holder 20 along the first circumferential direction. Each blade 21 is a bendable steel wire. The first end of each blade 21 is connected to the blade holder, and the second end of each blade is a free end extending outward toward the side wall of the corresponding lower chamber 12. This allows each cutter body 21 to bend and arrange itself in a clockwise or counterclockwise rotational direction when rotated by the cutter holder 20. Furthermore, the degree of bending of each cutter body 21 is adjusted accordingly with the motor speed. Figure 4As shown, the blade body 21 in the dashed line portion and the blade body in the solid line portion represent two different rotational speeds. The cutting range of the blade body 21 in the two forms is different (the cutting range of the blade body in the dashed line portion is larger), which avoids the situation of insufficient mixing and the formation of lumps in the prior art.

[0037] The grinding ring 4 and the grinding disc 5 that cooperates with the grinding ring 4 are disposed inside the crushing chamber, above the crushing blade 2. The grinding ring 4 is disposed on the inner wall surface of the crushing chamber along the first circumference. The circular grinding disc 5 is placed horizontally around the inner circumference of the grinding ring 4 to divide the crushing chamber into an upper chamber 11 located above the grinding disc 5 and having the aforementioned feeding port 10, and a lower chamber 12 located below the grinding disc 5 and having the aforementioned crushing blade 2. The depth dimension of the upper chamber 11 in the vertical direction is greater than the depth dimension of the lower chamber 12 in the vertical direction. The crushing blade 2 is relatively close to the bottom wall of the lower chamber 12 and relatively far away from the grinding disc 5. The central part of the grinding disc 5 is connected to the upper end of the motor shaft through a connecting shaft 31. The connecting shaft 31 is arranged coaxially with the motor shaft so that the grinding disc 5 can rotate around the first axis and circumferentially relative to the grinding ring 4 under the drive of the motor to grind the soybeans entering from the feeding port 10. Meanwhile, a through hole is provided between the grinding disc 5 and / or the grinding ring 4 and / or the grinding disc 5 and the grinding ring 4 for the ground soybeans to pass through, and the through hole connects the upper chamber 11 and the lower chamber 12. In this embodiment, the grinding ring 4 has a vertically extending first ring wall 41 and a second ring wall 42 extending inward from the lower periphery of the first ring wall 41. The grinding ring 4 has a plurality of L-shaped holes 40 spaced apart along the first circumference as the aforementioned through holes. The vertical portion 401 of each L-shaped hole 40 is located on the lower side of the first ring wall 41, and the horizontal portion 402 is located on the second ring wall 42 and penetrates the inner periphery of the second ring wall 42. The grinding disc 5 is located on the second ring wall 42, and the edge of the grinding disc 5 is spaced apart from the first ring wall 41. An impact hammer 51 is provided on the upper surface of the grinding disc 5. There are two impact hammers 51, which are arranged opposite each other on both sides of the first axis 30 and are located near the edge of the grinding disc 5. Furthermore, the grinding disc 5 is provided with multiple filter holes 50 that penetrate the thickness of the disc as the aforementioned through holes. Multiple filter holes 50 arranged radially at intervals form a group, and there are multiple groups arranged at intervals along the first circumferential direction.

[0038] Meanwhile, the side wall of the upper chamber 11 is provided with an air blowing hole 111 to allow external air to enter the upper chamber 11.

[0039] In this embodiment, the grinding ring 4 and the grinding disc 5 that cooperates with the grinding ring are designed to perform preliminary grinding on the soybeans entering from the feeding port 10. After grinding, the soybeans with smaller particle sizes enter the lower chamber 12 through the through hole, where they are further broken down by the cutting action of the wall-breaking blade 2. At this time, because the soybean particles are smaller, the wear rate on the wall-breaking blade is reduced. Furthermore, the grinding action of the grinding disc and grinding ring, as well as the cutting action of the wall-breaking blade, ensure the wall-breaking effect on the soybeans.

[0040] Furthermore, when the soymilk maker is working, the minimum water volume inside generally covers the grinding disc 5. The design of the grinding disc 5, which is positioned above the blending blade 2, results in a smaller volume in the lower chamber 12 where the blending blade 2 is located. This reduces the liquid flow height during blending, making it easier for the blending blade 2 to cut and crush the food. In this embodiment, the structural design of the blending blade 2 also improves the pulverization effect on food ingredients.
