[0054] The implementation, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0057] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0058] In a full-automatic wall breaker, the same wastewater holes are used to discharge the wastewater of the washed food materials and the wastewater of the washed pulp residues. When the gaps of the wastewater holes are relatively large, it is easy to leak the food materials. When the gaps of the wastewater holes are relatively small, it is easy to jam large particle residues and is not convenient for cleaning.

[0059] In view of this, the present invention provides a food processor, and the food processor includes a slurry discharge valve assembly. Any food processor including the slurry discharge valve assembly is within the protection scope of the present invention. In the present invention, the structure of the existing slurry discharge valve assembly is optimized, and the user experience is improved. Among them, Figures 1 to 11 is a schematic structural diagram of an embodiment of the slurry discharge valve assembly provided by the present invention.

[0060] Please refer to Figures 1 to 4 , a fluid passage 1 is formed in the slurry discharge valve assembly 100.

[0061] The slurry discharge valve assembly 100 includes a filtering assembly 2. A waste discharge filtering portion 211 is formed on the filtering assembly 2. Waste discharge filtering holes 211a are provided on the waste discharge filtering portion 211. The waste discharge filtering portion 211 can be located in the fluid passage 1. The size of the waste discharge filtering holes 211a is adjustable so that the waste discharge filtering portion 211 has multiple filtering states to adapt to discharging different fluids from the fluid passage 1.

[0062] In the technical solution provided by the present invention, a fluid passage 1 is formed in the slurry discharge valve assembly 100. Waste discharge filtering holes 211a are provided on the waste discharge filtering portion 211. The waste discharge filtering portion 211 can be located in the fluid passage 1. The size of the waste discharge filtering holes 211a is adjustable so that the waste discharge filtering portion 211 has multiple filtering states. When the waste discharge filtering holes 211a are relatively small, it can prevent substances of a certain particle size (such as food materials) from being discharged with the wastewater. When the waste discharge filtering holes 211a are relatively large, impurities with larger particles can be discharged with the wastewater, which is convenient for cleaning food residue, and it adapts to discharging different fluids from the fluid passage 1. In this way, the leakage of food materials is reduced, and the probability of large particle residue jamming is also reduced, having a good effect.

[0063] It should be noted that the present invention does not limit the way of adjusting the size of the waste discharge filtering holes 211a. For example, it can be achieved by adjusting the overlapping area of two filtering holes, or by local deformation of the waste discharge filtering portion 211.

[0064] Specifically, in the embodiment of adjusting the overlapping area of two filtering holes, by providing two filter plates, filtering holes are provided on each of the filter plates. The two filtering holes are stacked along the axial direction of the fluid passage 1. At least one of the filter plates moves in the radial direction of the fluid passage 1 to change the overlapping area of the two opposite filtering holes. In this way, the adjustment of the size of the waste discharge filtering holes 211a is achieved.

[0065] Specifically, when the two filter plates are arranged oppositely, the two filtering holes face each other, and at this time the flow-through area is the largest. When the part without holes on one of the filter plates covers the filtering holes on the other filter plate, the conduction area between the two filter plates gradually shrinks. By changing the relative position between the two filter plates, the passing area of the fluid can be quickly adjusted. At this time, the waste discharge filtering holes 211a are the overlapping conduction area of the filtering holes on the two filter plates.

[0066] The moving mode of the filter plate can be set to a linear moving mode. For example, it can be realized by structures such as cylinders and oil cylinders with linear moving strokes, or it can be realized by converting rotational motion into linear motion through structures such as gears and racks. Details are not described here.

[0067] In other cases, in embodiments where local deformation of the waste discharge filtering part 211 is adopted, the waste discharge filtering holes 211a are arranged at the positions where the waste discharge filtering part 211 can deform. After the waste discharge filtering part 211 deforms, the size of the waste discharge filtering holes 211a will change.

[0068] The local deformation of the waste discharge filtering part 211 can be realized by mechanical means, such as bending force or pressing force, or can also be realized by changing the temperature.

[0069] Specifically, in one embodiment, when the waste discharge filtering part 211 is in the fluid passage 1, a pushing structure can be arranged in the fluid passage 1, and the waste discharge filtering part 211 is pushed by the pushing force extending along the axial direction of the fluid passage 1 to realize the deformation of the waste discharge filtering part 211. For example, the waste discharge filtering part 211 can be a sheet metal part or an elastic part, which is easy to deform along its thickness direction.

[0070] It can also be to fix one end of the waste discharge filtering part 211 in the radial direction of the fluid passage 1, and a lateral pushing force is applied to the other end of the waste discharge filtering part 211 to realize the deformation of the waste discharge filtering part 211. For example, the waste discharge filtering part 211 can be a sheet metal part or an elastic part, which is easy to deform along its thickness direction. The above two methods are both embodiments of the present invention.

[0071] In one embodiment, please refer to Figures 3 to 5 , the material of the waste discharge filtering part 211 includes shape memory alloy material. The waste discharge filtering part 211 deforms with the change of its own temperature. By changing the ambient temperature of the waste discharge filtering part 211, the deformation of the waste discharge filtering part 211 can be realized, and then the size of the waste discharge filtering holes 211a can be quickly changed, and the adjustment is simple and convenient.

[0072] Shape memory alloy is a material composed of two or more metal elements that has a shape memory effect through thermoelastic and martensitic phase transformations and their inversions. Shape memory alloy is the material with the best shape memory performance among shape memory materials.

[0073] The reason why shape memory alloys have the ability to deform and recover is due to the thermoelastic martensitic transformation that occurs within the material during the deformation process. Shape memory alloys have two phases: the high-temperature austenite phase and the low-temperature martensite phase. Depending on different thermomechanical load conditions, shape memory alloys exhibit two properties.

[0074] The shape memory effect includes the one-way memory effect, the two-way memory effect, and the full-range memory effect. Shape memory alloys deform at a lower temperature and can recover their pre-deformed shape after heating. This shape memory phenomenon that only exists during the heating process is called the one-way memory effect; some alloys can recover their high-temperature phase shape when heated and their low-temperature phase shape when cooled, which is called the two-way memory effect; when heated, they recover their high-temperature phase shape, and when cooled, they change into a low-temperature phase shape with the same shape but opposite orientation, which is called the full-range memory effect.

[0075] In the embodiments of the present invention, the waste discharge and filtration part 211 can be made of a material with the one-way memory effect or a material with the two-way memory effect.

[0076] The shape memory effect of shape memory alloys stems from the thermoelastic martensitic transformation. Once this martensite is formed, it will continue to grow as the temperature drops and decrease when the temperature rises, disappearing in a completely opposite process. The difference in the free energy of the two phases serves as the driving force for the phase transformation. The temperature T0 at which the free energies of the two phases are equal is called the equilibrium temperature. Martensitic transformation only occurs when the temperature is lower than the equilibrium temperature; conversely, inverse transformation only occurs when the temperature is higher than the equilibrium temperature.

[0077] In the embodiments of the present invention, the martensitic transformation temperature of the waste discharge and filtration part 211 is T, and 50°C ≤ T ≤ 60°C. In a preferred embodiment, T = 55°C. Corresponding to the embodiment where the waste discharge and filtration part 211 is a part of the moving valve plate 21, the temperature of the moving valve plate 21 at room temperature (mainly generated by the friction when the moving valve plate acts) is 30°C - 40°C, and in the heated state, the temperature of the moving valve plate 21 is 50°C - 60°C. At the above temperatures, the waste discharge and filtration part 211 can quickly feedback according to the temperature change and then quickly adjust the size of the waste discharge and filtration holes 211a.

[0078] In shape memory alloys, martensitic transformation can be caused not only by temperature but also by stress. This martensitic transformation caused by stress is called stress-induced martensitic transformation, and the phase transformation temperature has a linear relationship with the stress.

[0079] Memory alloy systems discovered: Au-Cd, Ag-Cd, Cu-Zn, Cu-Zn-Al, Cu-Zn-Sn, Cu-Zn-Si, Cu-Sn, Cu-Zn-Ga, In-Ti, Au-Cu-Zn, NiAl, Fe-Pt, Ti-Ni, Ti-Ni-Pd, Ti-Nb, U-Nb, Fe-Mn-Si, etc.

[0080] In the above memory alloy materials, by adjusting different alloying elements and / or the proportions of alloying elements, the change of martensitic transformation is achieved.

[0081] It should be noted that in the food processor, operations such as cleaning ingredients, processing, discharging slurry, and cleaning slurry residues need to be carried out. For the above different operating states, the slurry discharge valve assembly 100 needs to have different functions.

[0082] In one embodiment, the filtering assembly 2 includes a movable valve plate 21.

[0083] Specifically, the waste discharge filtering portion 211 is provided on the movable valve plate 21. The movable valve plate 21 moves radially along the fluid passage 1. Along its moving direction, slurry discharge holes 212 are also provided on the movable valve plate 21 at intervals from the waste discharge filtering portion 211, and a partition portion 213 is formed between the waste discharge filtering portion 211 and the slurry discharge holes 212.

[0084] On the moving stroke of the movable valve plate 21, the slurry discharge holes 212, the partition portion 213, and the waste discharge filtering portion 211 are alternately located in the fluid passage 1. The slurry discharge holes 212 and the waste discharge filtering portion 211 are used to conduct the fluid passage 1, and the partition portion 213 is used to block the fluid passage 1.

[0085] Thus, please refer to Figures 6 to 11 , when the partition portion 213 is located in the fluid passage 1, the slurry discharge valve assembly 100 blocks the fluid passage 1, and at this time, there is no fluid discharge in the fluid passage 1; when the waste discharge filtering portion 211 is located in the fluid passage 1 and the waste discharge filtering portion 211 is in the state of filtering the ingredients being cleaned, the slurry discharge valve assembly 100 realizes the function of discharging waste during ingredient cleaning; when the waste discharge filtering portion 211 is located in the fluid passage 1 and the waste discharge filtering portion 211 is in the state of filtering the slurry residues being cleaned, the slurry discharge valve assembly 100 realizes the function of discharging waste during slurry residue cleaning; when the slurry discharge holes 212 are located in the fluid passage 1, the slurry discharge valve assembly 100 realizes the function of rapid slurry discharge.

[0086] Through the movement of the movable valve plate 21, various functions of the slurry discharge valve assembly 100 such as cleaning ingredients, processing, discharging slurry, and cleaning slurry residues are realized, improving the user experience.

[0087] It should be noted that after the slurry is made in the food processor, it can be quickly discharged through the slurry discharge hole 212. The slurry discharge hole 212 can be a hole with a relatively large area, and its size is equivalent to the cross-section of the fluid passage 1, so that the slurry in the food processor can be quickly discharged.

[0088] During the movement of the movable valve plate 21, the deformation process and the filtering state of the waste discharge filtering part 211 need to cooperate with the above movement process, so that when the waste discharge filtering part 211 is in the state of filtering washed ingredients, the waste discharge filtering part 211 deforms or returns to its original state, and when the waste discharge filtering part 211 is in the state of filtering washed pulp residues, the waste discharge filtering part 211 returns to its original state or deforms correspondingly.

[0089] Specifically, during the movement stroke of the movable valve plate 21, the movable valve plate 21 has a position for washing ingredients, a slurry discharge position, a position for washing pulp residues, and a blocking position. When in the position for washing ingredients and the position for washing pulp residues, the waste discharge filtering part 211 is in the fluid passage 1. When in the slurry discharge position, the slurry discharge hole 212 is in the fluid passage 1. When in the blocking position, the partition part 213 is in the fluid passage 1.

[0090] The food processor has a pulping process. Correspondingly, within the pulping process, the movable valve plate 21 sequentially switches between the position for washing ingredients, the blocking position, the slurry discharge position, the blocking position, the position for washing pulp residues, and the blocking position, and the total time for the movement of the movable valve plate 21 is T1.

[0091] The deformation and recovery time of the waste discharge filtering part 211 is T0, and 1 second < T0 ≤ T1.

[0092] Within the above time range, the deformation process of the waste discharge filtering part 211 can well adapt to the switching of the slurry discharge valve assembly 100 between different functions, improving the user experience.

[0093] Of course, it should be noted that in this pulping process, the total time for the movement of the movable valve plate 21 does not include the time for boiling soy milk, the time for manually discharging soy milk, etc., and only represents the time consumed during the continuous movement process of the movable valve plate 21.

[0094] Specifically, for example, if the moving valve plate 21 switches and pauses for 4 seconds between each of the positions at the food cleaning position, the blocking position, the slurry discharging position, the blocking position, the cleaning slurry residue position, and the blocking position in sequence, the total time is 24 seconds. Then, the deformation time for the waste discharging and filtering part 211 to switch between the food cleaning filtering state and the cleaning slurry residue filtering state can be set to be less than or equal to 24 seconds.

[0095] It should be noted that during the movement of the moving valve plate 21, the end face of the moving valve plate 21 (except for the slurry discharging hole 212 and the waste discharging and filtering part 211) is always sealed with the fluid passage 1, that is, the deformation of the waste discharging and filtering part 211 does not affect the movement of the moving valve plate 21.

[0096] Specifically, in one embodiment, the filtering assembly 2 includes a moving valve plate 21, the waste discharging and filtering part 211 is arranged on the moving valve plate 21, the moving valve plate 21 moves along the radial direction of the fluid passage 1, and the waste discharging and filtering part 211 extends into the fluid passage 1. The moving valve plate 21 has two sealing sides in its thickness direction.

[0097] In the multiple filtering states, the waste discharging and filtering part 211 is always between the two sealing sides. With such a setting, the movement of the moving valve plate 21 is not interfered, and the moving valve plate 21 switches smoothly between the above positions, having a good effect.

[0098] In one embodiment, the waste discharging and filtering part 211 includes a waste discharging hole 2111 and a plurality of grid bars 2112 arranged in the waste discharging hole 2111.

[0099] The waste discharging filter holes 211a are formed at intervals between adjacent grid bars 2112.

[0100] At least part of the grid bars 2112 can deform to change the size of the waste discharging filter holes 211a.

[0101] By arranging a plurality of grid bars 2112, the grid bars 2112 can deform, thereby changing the size of the waste discharging filter holes 211a, and the adjustment is simple and convenient.

[0102] Specifically, within the waste discharge hole 2111, along the thickness direction of the movable valve plate 21, the grid bars 2112 can be arranged at the middle position of the movable valve plate 21. When bending within the waste discharge hole 2111, the grid bars 2112 can bend towards any one side end of the movable valve plate 21; when the grid bars 2112 are arranged flush with one side end face of the movable valve plate 21, the grid bars 2112 are arranged to deform towards the other side end of the movable valve plate 21.

[0103] In one embodiment, the multiple filtering states include the state of filtering while cleaning ingredients. In the state of filtering while cleaning ingredients, the distance between adjacent grid bars 2112 is D, and 0 < D ≤ 0.8 mm.

[0104] In the above-mentioned passing distance, for example, if the smallest processed ingredient is sesame, in the state of filtering while cleaning ingredients, sesame can be prevented from being discharged from the processing cup assembly.

[0105] It should be noted that the multiple grid bars 2112 can be welded within the waste discharge hole 2111 or bonded to the movable valve plate 21.

[0106] Specifically, in the embodiment where the multiple grid bars 2112 are welded within the waste discharge hole 2111, the two ends of the grid bars 2111 can respectively abut against the inner wall surface of the waste discharge hole 2111, and the lengths of the multiple grid bars 2111 are different; it can also be that a limiting groove is opened on one side end face of the movable valve plate 21, and the grid bars 2111 are arranged within the limiting groove. At this time, the multiple grid bars 2111 can be arranged to have the same length.

[0107] In the embodiment where the multiple grid bars 2112 are bonded to the movable valve plate 21, a limiting groove can be opened on one side end face of the movable valve plate 21, and structural adhesive is arranged between the inner side wall of the limiting groove and the outer side face of the grid bars 2112 for bonding. At this time, the multiple grid bars 2111 can also be arranged to have the same length.

[0108] Of course, no matter how the grid bars 2111 are quickly arranged on the movable valve plate 21, the grid bars 2111 are always within the two sealing side faces of the movable valve plate 21.

[0109] In another embodiment, the multiple filtering states include the state of filtering while cleaning ingredients and the state of filtering while cleaning pulp residues.

[0110] The conduction area of the waste discharge filtering hole 211a corresponding to the state of filtering while cleaning ingredients is smaller than the conduction area corresponding to the state of filtering while cleaning pulp residues.

[0111] That is, while ensuring that the ingredients can be prevented from leaking during the state of filtering the washed ingredients, rapid slurry discharging operation can be achieved, the waiting time of the user can be reduced, and the user experience can be improved.

[0112] It should be noted that taking the food processor as a wall breaker as an example, in the food processor, the slurry discharging valve assembly 100 further includes a first valve plate structure 3 and a second valve plate structure 4.

[0113] The first valve plate structure 3 has a first fluid passage 31.

[0114] The second valve plate structure 4 has a second fluid passage 41. The second valve plate structure 4 is connected to the first valve plate structure 3, and the second fluid passage 41 can communicate with the first fluid passage 31.

[0115] The fluid passage 1 includes the first fluid passage 31 and the second fluid passage 41.

[0116] The filtering component 2 is arranged between the first valve plate structure 3 and the second valve plate structure 4.

[0117] The filtering component 2 includes a movable valve plate 21. By sealing and moving the movable valve plate 21 between the first valve plate structure 3 and the second valve plate structure 4, the food processor can be switched between the state of discharging waste water and the state of discharging slurry.

[0118] In one embodiment, the first valve plate structure 3 includes a first valve plate.

[0119] The first fluid passage 31 penetrates through the first valve plate.

[0120] The second valve plate structure 4 includes a second valve plate, and the second fluid passage 41 penetrates through the second valve plate.

[0121] The first valve plate, the movable valve plate 21 and the second valve plate are closely attached in sequence, that is, the first valve plate, the movable valve plate 21 and the second valve plate are sealed on the fluid flow path, so as to avoid the leakage of fluid from the outer periphery of the movable valve plate 21.

[0122] In this embodiment, the flatness of the surface of the first valve plate close to the movable valve plate 21, the opposite two surfaces of the movable valve plate 21, and the surface of the second valve plate close to the movable valve plate 21 is not lower than 0.1 mm. The roughness of the surface of the first valve plate close to the movable valve plate 21, the opposite two surfaces of the movable valve plate 21, and the surface of the second valve plate close to the movable valve plate 21 is not lower than 0.4 μm. In this way, the first valve plate, the movable valve plate 21 and the second valve plate have better sealing performance on the fluid passage 1.

[0123] In this embodiment, the material of the first valve plate includes at least one of ceramics, stainless steel, and alloy. The material of the second valve plate includes at least one of ceramics, stainless steel, and alloy. The material of the moving valve plate 21 includes at least one of ceramics, stainless steel, and alloy. In this embodiment, the materials of the first valve plate, the second valve plate, and the moving valve plate are the same. It can be understood that in other embodiments, the materials of the first valve plate, the second valve plate, and the moving valve plate 21 may also be different.

[0124] In addition, it should be noted that the slurry discharge valve assembly 100 further includes a slurry discharge pipe 5. The inner cavity of the slurry discharge pipe 5 communicates with the second fluid passage 41. A processing cup assembly is also provided in the food processor, and the inner cavity of the processing cup assembly communicates with the first fluid passage 31. That is, the connection between the processing cup assembly and the outside is realized through the action of the slurry discharge valve assembly 100.

[0125] In one embodiment, a bracket is provided on the moving valve plate 21. Driving the movement of the bracket can quickly realize the movement of the moving valve plate 21. A linear drive structure can be used to achieve this. The linear drive structure can be a cylinder, an oil cylinder, an electric push rod, etc. In one embodiment, the linear drive structure includes a drive motor and a gear-rack transmission mechanism. The gear-rack transmission mechanism includes a gear and a rack that mesh with each other. The gear is drivingly connected to the drive motor, and the rack is fixedly connected to the bracket. The movement of the bracket is driven through the cooperation of the drive motor and the gear-rack transmission mechanism, which is convenient for controlling the movement stroke of the moving valve plate 21.

[0126] It should be noted that in the form of the gear-rack transmission mechanism, the external meshing method between the gear and the rack also has a good self-locking function, which improves the stability of the linear drive structure. In addition, in the form of using the drive motor as the power source, it is convenient to control the drive motor through a circuit, making the control of the movement stroke of the moving valve plate 21 more accurate.
