Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a food processing machine. Background Art

[0002] Freshly squeezed juice can be divided into two categories: pure juice and whole juice. Pure juice is juice with pomace and juice separated after processing (i.e. juice without pomace); whole juice is juice crushed with skin, pulp and core (i.e. juice with pomace). These two types of juice have their own advantages and disadvantages: pure juice tastes good but lacks dietary fiber, resulting in incomplete nutrition; whole juice retains all dietary fiber but also has a relatively poor taste.

[0003] In the prior art, machines for making pure juice mainly include spiral juicers (which are divided into vertical and horizontal types), centrifugal juicers and piston squeeze juicers. All of the above juicers can produce "juice with residue and juice separated". The raw materials of each machine are similar, but the specific technical structures are different.

[0004] In the prior art, the machines for making full juice mainly include blenders and soymilk machines, and their specific structures generally include three types: upper-mounted grinding motor type, lower-mounted grinding motor type, and side-mounted grinding motor type. Both blenders and soymilk machines grind fruits (food materials) and water into juice by rotating the grinding cutter device in the barrel. It is customary to call a low-power blender of about 100 to 200 watts a food processor; a high-power blender of about 1000 watts is called a wall-breaking machine (high-power blending is more delicate). Soymilk machines are essentially also a blender, so soymilk machines can also be regarded as a customary name for a certain type of blender with a heating device, and it still belongs to a blender in terms of technical classification.

[0005] Machines for making pure juice and whole juice include vacuum models and non-vacuum models. The advantage of vacuum models is that they can avoid oxidation of the juice.

[0006] The existing machines for making pure juice, such as CN201710065637.2 "Electric Driven Vacuum Press", CN201610498366.5 "Electric Driven Closed Vacuum Press", etc., are all vacuum piston squeeze juicers, which can not only prevent juice oxidation during use, but also have fewer parts to be cleaned after squeezing the juice. Only the squeezing cylinder, piston and juice receiving part need to be cleaned, and other parts of the machine body do not need to be cleaned.

[0007] However, existing machines can only produce "pure juice separated from pulp juice" but cannot produce "full juice containing pulp".

[0008] Among the machines for making whole juice with current technology, such as the food processor disclosed in CN201210139784.7 "Food processor with electric vacuum pump and method for preparing food liquid by vacuuming", can only make "whole juice containing pomace" but cannot make "pure juice separated from pomace".

[0009] As mentioned above, the two major types of food processors in the prior art, represented by squeezers and blenders, can only process one type of juice, either whole juice or pure juice. No food processor can produce whole juice and pure juice at the same time, and the production of different juices can only be achieved through two food processors.

[0010] On the other hand, the current mainstream residential building area of ​​Chinese residents is only about 100 square meters, of which the kitchen area is generally only about 4 square meters. The total length of the countertop in the kitchen is generally only 3 to 4 linear meters. After deducting the countertop area that must be occupied by "first-level rigid necessities" such as stoves, sinks, cutting boards, dishes, and rice cookers, the remaining countertop area is very small. Therefore, in Chinese residents' kitchens, there is often a place for blenders but no place for juicers, and vice versa. Summary of the invention

[0181] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments.

[0182] like Figure 1 and Figure 2 As shown, in the first embodiment of the food processor of the present invention, it includes a body 1, an electric drive mechanism and a control unit (not shown) arranged on or in the body, the electric drive mechanism includes a main body and an action part, and the food processor also includes a pressing component and a stirring component. In this embodiment, the body 1 is a "C"-shaped structure, which is divided into a head part 1a, a base part 1b and a support part 1c. The support part is arranged between the head part and the base part and supports the head part and the base part. The head part is a cantilevered structure relative to the support part, and a pressing / stirring working space is formed between the cantilevered part of the head part and the part of the base part extending out of the support part, and a pressing component or a stirring component is arranged in the pressing / stirring working space on the body.

[0183] The squeezing assembly includes a squeezing cylinder 2, a piston 3 located in the squeezing cylinder, and a juice receiving part 4 connected to the squeezing cylinder. The piston divides the squeezing cylinder into an operating chamber 5 and a squeezing chamber 6. The operating chamber and the squeezing chamber can be connected to each other or isolated from each other. A juice receiving chamber 7 is formed between the juice receiving part and the squeezing cylinder. The squeezing chamber is connected to the juice receiving chamber. A filter screen 8 is arranged between the squeezing chamber and the juice receiving chamber. When the piston squeezes the raw material, the juice in the squeezing chamber passes through the filter screen and enters the juice receiving chamber. The filter screen and the squeezing cylinder can be an integrated structure or a split structure.

[0184] The stirring assembly includes a barrel body 9, a knife shaft 10 and a crushing tool 11. The crushing tool is located in the barrel body and is arranged on the knife shaft. The opening of the barrel body is provided with a barrel cover 16, which covers the barrel body. The barrel cover may not be provided according to actual conditions.

[0185] The pressing component and the stirring component are separate structures from the machine body, and one of the pressing component and the stirring component is detachably arranged in the pressing / stirring work space on the machine body. When the pressing component is arranged on the machine body, the food processor can produce pure juice without pomace through the piston and the pressing cylinder, and when the stirring component is arranged on the machine body, the food processor can produce full juice containing pomace through the barrel and the crushing cutter. The production of pure juice or full juice can be completed by replacing the pressing component or the stirring component in the machine body; the pressing component and the stirring component are replacement structures relative to the machine body, and the two cannot be used at the same time, that is, only pure juice or full juice can be selectively produced.

[0186] The electric drive mechanism is divided into a squeezing drive mechanism and a stirring drive mechanism. The squeezing drive mechanism is arranged in or on the machine body, and the stirring drive mechanism is arranged in or on the machine body. The squeezing drive mechanism includes a piston drive body 12 and a piston action part 13. The piston action part is fixedly connected to the piston, detachably connected to the piston, or just pressed against the piston. The remaining parts of the squeezing drive mechanism except the piston action part are collectively referred to as the piston drive body. The piston action part can be extended and retracted under the drive of the piston drive body, and is used to push / pull the piston to make the piston squeeze or squeeze the material to be squeezed in the squeezing chamber; or, the piston action part can also be an eccentric swinging mechanism, which twists, swings, and shakes under the drive of the piston drive body to squeeze and drive the piston to move, so that the piston further squeezes or squeezes the material to be squeezed in the squeezing chamber.

[0187] The pressing drive mechanism includes but is not limited to: any one of electric push rods, electric cylinders, linear travel motors, through-type screw linear stepper motors, electric rack jacks, electric hydraulic push rods, electric hydraulic jacks, electric hydraulic lifting mechanisms, electric pneumatic push rods, electric screw lifters, electric crankshaft connecting rod telescopic mechanisms, electric camshaft connecting rod telescopic mechanisms, electric crank slider telescopic mechanisms, electric worm gear connecting rod telescopic mechanisms, electric scissor jacks, electric screw telescopic mechanisms, electric ball screw lifting mechanisms, electric turbine screw telescopic mechanisms, electric scissor lift mechanisms, electric sleeve cylinder lifting mechanisms, electric column lifting mechanisms, electric crank arm lifting mechanisms or electric chain lifting mechanisms, or any combination of any two or more. The pressing drive mechanism can also be other replaceable solutions or known technologies in the prior art that can achieve the technical effect of fixed connection, detachable connection with the piston, or simply pressing the piston and driving the piston to move.

[0188] For example, the pressing drive mechanism is an electric push rod. An electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The electric push rod consists of a drive motor, a reduction gear, a screw, a nut, a guide sleeve, a push rod, a slide seat, a spring, a housing, a turbine, a micro-control switch, etc. After the motor is reduced by the gear, it drives the screw nut. The rotational motion of the motor is converted into linear motion, and the push rod action is completed by the forward and reverse rotation of the motor. At this time, the push rod is the piston action part, and the rest of the parts are the piston drive body.

[0189] For another example, the pressing drive mechanism is an electric hydraulic push rod, in which the electric motor is used as the power source, and the pressure oil is output through the gear pump, and is controlled by the oil circuit manifold to the oil cylinder to realize the movement of the piston rod. At this time, the piston rod is the piston action part, and the rest are the piston drive body.

[0190] In addition to the telescopic method, the piston action part can also drive the piston through other motion methods, including but not limited to rotation, torsion, swing or shaking, etc. For example, a piston action part that can rotate in a circle around the axis by using a cam, crank, crankshaft, etc., a piston action part that can swing in an arc in one direction or reciprocatingly around the axis by using a swing arm, etc., or a piston action part that can be a squeeze block driven by a piston driving body, etc. The cam, crank, crankshaft can also make a one-way or reciprocating swinging motion in an arc under the drive of the piston driving body. The main working principle of the piston action part is to drive the piston movement during the rotation, swinging and other motions.

[0191] When the cam, crankshaft and other parts farthest from the axis rotate to the piston, they squeeze it and make the piston move; when the outer end of the swing arm and crank rotates to the piston, they squeeze it and make the piston move; when the extrusion block is turned, its end close to the piston squeezes the piston and makes the piston move.

[0192] The piston driving body realizes the squeezing or extrusion of the material to be squeezed in the squeezing chamber, and mainly drives the piston action part, which provides power.

[0193] The stirring drive mechanism further includes a blade shaft driving body 14 and a blade shaft action part 15, wherein the blade shaft action part is fixedly connected or detachably connected to the blade shaft, wherein the blade shaft action part is a component used to connect and / or drive the blade shaft to rotate, and the rest of the components are the blade shaft driving body, and the blade shaft action part drives the blade shaft to rotate under the drive of the blade shaft driving body. The blade shaft driving body is usually an electric motor, and in this case, the blade shaft action part can be a connecting component connected to the blade shaft, and the motor transmits power to the blade shaft through the blade shaft action part.

[0194] For example, with an electric motor as the power source, the output shaft of the motor is directly connected to the knife shaft and drives the knife shaft to rotate. At this time, the output shaft of the motor is the knife shaft action part, and the rest of the parts are the knife shaft drive body.

[0195] For example, an electric motor is used as the power source to drive the hydraulic pump to output pressure oil, which is controlled by the oil circuit integrated block to the hydraulic motor. The liquid pressure energy is converted into mechanical energy of the hydraulic motor output shaft. The output shaft of the hydraulic motor drives the knife shaft to rotate. At this time, the output shaft of the hydraulic motor is the knife shaft action part, and the rest of the parts are the knife shaft drive body.

[0196] The pressing drive mechanism is an electric drive mechanism used to drive the piston movement. As long as it uses electricity as the power source and can drive the piston movement through hydraulic pressure, pneumatic pressure or other mechanical devices, it can be regarded as a pressing drive mechanism.

[0197] The stirring drive mechanism is an electric drive mechanism used to drive the blade shaft to rotate. As long as it uses electricity as a power source and can drive the blade shaft to rotate through hydraulic pressure, pneumatic pressure or other mechanical devices, it can be regarded as a stirring drive mechanism.

[0198] The above definitions and descriptions of the piston driving body, the piston actuating part, the knife shaft driving body and the knife shaft actuating part in the pressing driving mechanism and the stirring driving mechanism are the same as the descriptions of other embodiments in the present invention.

[0199] In this embodiment, the piston driving body 12 and the blade shaft driving body 14 have a common structure, and all or part of the piston driving body and all or part of the blade shaft driving body are the same mechanism. For example, the motor in the piston driving body as a power output component is the motor in the blade shaft driving body, or the piston driving body and the blade shaft driving body are the same mechanism, and the piston action part 13 and the blade shaft action part 15 are the same component, and the component also has a structure connected to the piston or a structure that presses the piston and a structure connected to the blade shaft, or the piston action part and the blade shaft action part can be replaced together with the pressing component or the stirring component. At the same time, the component (action part) can drive the piston to move in the pressing cylinder (squeeze the material to be pressed in the pressing chamber) and can also drive the blade shaft to rotate (crush the material to be crushed in the barrel).

[0200] The control unit sends corresponding control signals to the pressing drive mechanism or the stirring drive mechanism to make it work:

[0201] When the squeezing assembly is arranged on the machine body: the piston action part drives the piston to move according to the control signal and squeezes or presses the object to be squeezed in the squeezing chamber, and the squeezed or squeezed juice flows into the juice receiving part; or

[0202] When the stirring assembly is arranged on the machine body, the knife shaft action part drives the knife shaft to rotate according to the control signal, and crushes the objects to be crushed in the barrel.

[0203] like Figure 3 As shown, in the second embodiment of the food processor of the present invention, it includes a body 1, an electric drive mechanism and a control unit arranged on or in the body. In this embodiment, the body 1 is a "C"-shaped structure, which is divided into a head portion 1a, a base portion 1b and a support portion 1c. The support portion is arranged between the head portion and the base portion and supports the head portion and the base portion.

When the squeezing assembly is arranged on the machine body, the blade shaft action part presses against the piston, and the piston driving body drives the piston action part with the blade shaft driving body. At this time, the blade shaft driving body and the blade shaft action part can not perform any action, but only play the role of transmitting the movement of the piston action part to the piston, so that the piston completes the squeezing process of the object to be squeezed in the squeezing cylinder. Of course, during this process, when the squeezing cylinder and the piston are circular, the blade shaft driving body can also simultaneously drive the blade shaft action part to drive the piston to rotate together, so as to play the role of "rotational squeezing" of the material to be squeezed in the squeezing cylinder, making the squeezing more uniform.

When the pressing assembly is arranged on the machine body, the piston driving body drives the piston action part to act on the piston 3. At this time, the blade shaft driving body and the blade shaft action part do not act, and only play the role of connecting the machine head; of course, in this process, the blade shaft action part can also rotate. It plays the role of "rotational pressing" on the object to be pressed, and the piston completes the pressing process on the object to be pressed in the pressing cylinder under the drive of the piston action part. When a stirring assembly is provided on the machine body, the piston action part 13 is connected to the cutter shaft and the crushing tool, or, at this time, the piston driving body 12 and the piston action part 13 are disassembled, and the cutter shaft action part 15 is connected to the cutter shaft, and the cutter shaft driving body drives the cutter shaft action part with the piston driving body, but the piston driving body and the piston action part do not move, and only play the role of transmitting the power of the cutter shaft driving body to the crushing tool, and the crushing tool completes the crushing process of the object to be crushed in the barrel.
