Referring to fig. 1, the present invention discloses a food processor 300, wherein the food processor 300 can be a wall breaking machine, a juice extractor, a soymilk grinder, a meat grinder, a chopper, a filament cutter, a slicer, etc. having a blade. The food processor 300 of fig. 1 is a wall breaking machine, which is only one form of the food processor 300 and should not be construed as limiting the present invention.

Referring to fig. 2, a food processor 300 according to an embodiment of the present invention includes a base 100 and a mixing cup 200. The base 100 is used to support the blender cup 200. Alternatively, the blender cup 200 is disposed on the base 100. In the present embodiment, the mixing cup 200 is detachably provided on the base 100. The blender cup 200 is used to hold food. For example, the blender cup 200 may be used to hold food such as fruit and vegetables, beans, or meat.

Referring to fig. 2 and 3, in particular, the blending cup 200 includes a cup body 210, a blending blade 220, and a motor 230. The cup 210 is formed with a first receiving space 211 and a second receiving space 212. The first receiving space 211 and the second receiving space 212 are spaced apart. The first receiving space 211 receives food. The motor 230 is located in the second receiving space 212. The motor 230 is fixed in the second receiving space, the output end of the output shaft extends into the first receiving space 211 from the second receiving space 212, and the stirring blade 220 is located at the bottom of the first receiving space 211 and fixed at the output end of the output shaft.

Thus, when the motor 230 works, the motor 230 can drive the stirring blade 220 to rotate by driving the output shaft, so as to cut and stir the food placed in the first accommodating space 211.

In the related art, a motor is disposed in a base and connected to a power source through a plug, one end of a transmission structure is connected to an output shaft of the motor through a clutch, and the other end of the transmission structure is connected to a stirring blade through the clutch to drive the stirring blade to rotate. Because the motor is located the base, lead to the very big inconvenient use of base overall dimension and storage, user experience is relatively poor.

In the embodiment, the stirring cup 200 is internally provided with the stirring blade 220 and the motor 230 for driving the stirring blade 220 to rotate, the stirring blade 220 is directly connected with the output shaft of the motor 230, and the original clutch is omitted. Because the clutch transmits the reason of torsion as the transmission structure for the mixer can produce great noise when moving, cancels the clutch and has eliminated the defect that the noise is big promptly, makes whole food processor 300's volume also reduce simultaneously, carries and transports more lightly, has improved user experience.

In addition, the power of the motor 230 is less than or equal to 1500W, and further, the power of the motor 230 is 100-1500W. For example, the motor 230 has a power of 100W, 200W, 300W, 500W, 800W, 1000W, 1500W, or the like. Preferably, the power of the motor 230 is 500-. This allows the motor 230 to be powered to meet the requirements for blending and cutting food. Preferably, the motor 230 may be a brushless dc motor 230. In this embodiment, the operation of the motor 230 with different powers may be controlled according to the requirement, that is, the power of the motor 230 may be adjustable. For example, when the food processor 300 is processing a softer durometer substance, the motor 230 may be controlled to operate at a lower power; when the food processor 300 processes a hard substance, the motor 230 may be controlled to operate at a high power.

Preferably, in order to prevent the food material in the first receiving space 211 from contacting the motor 230 in the second receiving space 212, a sealing device is disposed to separate the two receiving spaces, so as to separate the food material from the motor.

Further, the bowl 210 may also include a measuring cup 213 and a lid 214 disposed on top of the bowl 210. A sealing ring 215 is fixed at the bottom of the cap 214. The measuring cup 213 is used for measuring the component of the food material to be processed, so as to precisely process the food material, the cup cover 214 is used for sealing the cup body 210, and a ring of sealing ring 215 is arranged at the bottom of the cup cover 214 in order to enable the cup cover 214 to be tightly combined with the cup body 210.

In some embodiments, the cup body 210 may be integrally formed, and further, the first receiving space 211 and the second receiving space 212 are opened, so that the overall sealing performance of the cup body 210 is better.

In some embodiments, the first receiving space 211 and the second receiving space 212 may be separately formed and further assembled into the cup 210. In such an embodiment, the first receiving space 211 and the second receiving space 212 may be connected by screwing, riveting, bonding, etc., and a fastener may be further added to the sidewall to reinforce the connection. Therefore, the upper and lower accommodating spaces can be conveniently detached for maintenance and cleaning.

Further, in such an embodiment, the bottom wall of the first receiving space 211 may be made of a metal material to heat the food in the cup 210 through the bottom wall, such as stainless steel, and at the same time, rust generated by long-time food receiving can be avoided. The side wall of the first receiving space 211 may be made of a transparent material such as glass, so that a user can observe the condition in the first receiving space 211. The side wall may be provided with a scale for measuring the volume of the first receiving space 211.

In some embodiments, two surfaces of the first receiving space 211 and the second receiving space 212 spaced apart from each other may be a bottom wall of the first receiving space 211 and a top wall of the second receiving space 212, respectively. In order to allow the output shaft to extend into the first receiving space 211 from the second receiving space 212, a through hole needs to be formed in the middle of the bottom wall of the first receiving space 211 or the top wall of the second receiving space 212, so that the output shaft of the motor 230 can pass through the through hole. The middle of the bottom wall or the top wall is the intersection of the center line of the cup body 210 and the bottom wall or the top wall, and the output shaft is the center line of the motor. That is, in such an example, the centerline of the motor 230 coincides with the centerline of the cup 210.

Referring to fig. 4, in some embodiments, a center line of the motor 230 and a center line of the cup 210 are parallel to each other, and a distance X between the center line of the motor 230 and the center line of the cup 210 is greater than or equal to 0.5mm and smaller than a radius of the bottom wall of the first receiving space 211 of the cup 210. Preferably, the distance X is 2-8 mm. Thus, the stirring efficiency is improved by using the turbulent flow effect generated by the eccentricity of the motor 230 with respect to the cup 210.

Referring to fig. 5, in some embodiments, the centerline of the motor 230 intersects the centerline of the cup 210, and the intersection angle between the centerline of the motor 230 and the centerline of the cup 210 is greater than or equal to 0.5 ° and less than or equal to 45 °, preferably, the intersection angle between the centerlines is 3-20 °. Thus, the stirring efficiency is improved by the turbulent flow effect generated by the inclination angle of the motor 230 relative to the cup 210.

Further, in some embodiments, in order to prevent the liquid of the food contained in the first containing space 211 from flowing into the second containing space 212, a sealing device such as a V-shaped sealing ring and an oil seal may be disposed at the through hole, and the sealing device may be clamped between the stirring blade 220 and the output shaft, thereby forming a waterproof structure. This ensures good and reliable sealing effect, and prevents the food material and liquid from entering the second receiving space 212.

Further, a shock pad may be further disposed in the second receiving space 212, and the shock pad may be disposed at a lower portion of the motor 230. The shock absorbing pad is made of an elastic material, such as a rubber pad, to reduce vibration and noise when the motor 230 operates.

In the present embodiment, the power of the motor 230 is less than or equal to 1500W, and the radius R of the motor 230 is less than or equal to 50 mm. Preferably, the radius R of the motor 230 is 40-50mm, for example, the radius R of the motor 20 is 40mm, 42mm, 45mm, 50mm, etc.

The motor 230 of the present embodiment is customized for the cup and motor integration requirement, and the transverse dimension of the motor 230 is small while satisfying the power requirement, which is beneficial to the miniaturization of the food processor 300. Meanwhile, since the motor 230 is not provided in the base 100, miniaturization of the base 100 is facilitated.

It is noted that the radius of the electric machine 230 refers to the radius of the smallest circle that envelopes the transverse dimension of the core of the electric machine 230.

Further, the height of the motor 230 is less than or equal to 60 mm. For example, the height of the motor 230 is 40mm, 42mm, 45mm, 60mm, or the like. In a typical motor, the height of the motor 230 with power of 200 and 1500W is typically greater than 70 mm. Therefore, the motor 230 of the present embodiment can meet the requirement of miniaturization of the food processor 300, and at the same time, the base 100, which no longer includes the motor 230, is made thinner.

In the present embodiment, the power of the motor 230 is 1500W or less, and the power density of the motor 230 is 0.8KW/kg or more. Preferably, the power density of the motor 230 is 0.8-1.2 KW/kg. For example, the motor 230 has a power density of 0.8KW/kg, 0.9KW/kg, 1KW/kg, 1.1KW/kg, 1.2KW/kg, etc.

Power density refers to the ratio of the mass of the motor 230 to the output power of the motor 230. Generally, to meet the power requirement of the motor 230, the more power the motor 230 needs, the more material is needed to manufacture the motor 230, so that the larger the volume of the motor 230, the larger the heat generation of the motor 230.

In the present embodiment, the power density of the motor 230 is greater than or equal to 0.8KW/kg, so that the heat generation amount of the motor 230 is small, and the temperature rise requirement is satisfied. When the power density of the motor 230 is in the above range, the heat sink such as a fan may be omitted from the base 100. That is, one end of the motor 230 does not need to be mounted with a heat dissipation fan, so that the height of the second receiving space 212 can be reduced, which is advantageous for the miniaturization of the food processor 300.

Further, the temperature rise range of the motor 230 is less than or equal to 120K. The temperature rise refers to the difference between the temperature of the motor 230 and the ambient air. When the temperature of the motor 230 rises within the above range, it means that the difference between the air temperature in the second receiving space and the temperature of the motor 230 is small, and it is not necessary to install a heat sink in the second receiving space 212, and it is also possible to ensure that the temperature of the corresponding portion of the cup 210 does not scald the user.

In the present embodiment, the ratio of the torque of the motor 20 at a low rotation speed to the torque of the motor 20 at a high rotation speed is greater than or equal to 0.7. Preferably, the ratio of the torque of the motor 230 at low speed to the torque of the motor 230 at high speed is 0.7-0.0.9, for example, the ratio of the torque of the motor 20 at low speed to the torque of the motor 20 at high speed is 0.7, 0.75, 0.8, 0.85, 0.9, etc.

Wherein the low rotation speed is less than 200r/min, for example, the low rotation speed is 80r/min, 90r/min, 100r/min, 120r/min, 150r/min, 180r/min, etc.

The high rotation speed is more than 3000r/min, for example, the high rotation speed is 3100r/min, 3500r/min, 4000r/min, 4500r/min, 5000r/min, 6500r/min and the like.

The torque of the machine 20 at low rotational speeds is greater than or equal to 2.8 n.m. Preferably, the torque of the motor 230 at low rotational speeds ranges from 2.8 to 3.2 n.m. For example, the torque of the motor 230 at a low rotation speed is a specific value such as 2.8n.m, 2.9n.m, 3.0n.m, 3.1n.m, 3.2n.m, and the like.

Generally, in an alternating current motor, the torque of the alternating current motor increases with an increase in the rotation speed, that is, the torque of the alternating current motor is smaller at a low rotation speed.

As described above, in the present embodiment, the motor 230 may be a dc brushless motor 230, and in addition, through a specific design, the motor 230 can operate with a large torque regardless of whether the motor 230 is at a low rotation speed or a high rotation speed, so that the motor 230 can have a good stirring effect on food at a low rotation speed.

Specifically, the electric machine 230 may include a stator, a rotor, and a bracket. The stator surrounds the rotor. The stator is fixed inside the bracket and is fixedly connected with the bracket. The rotor includes an output shaft that extends out of the bracket.

The bracket is formed with a plurality of lugs through which the motor is suspended and fixed on the top wall of the second receiving space 212.

In order to increase the heat dissipation speed of the stator and the rotor, it is preferable that the bracket is formed with a plurality of heat dissipation holes. It can be understood that heat generated by the stator and the rotor can be dissipated out of the motor through the heat dissipation holes.

Referring to fig. 6 and 7, in the present embodiment, the housing 10 may be made of plastic and/or metal. Specifically, the housing 10 includes a bottom cover 11, a surrounding wall 12, and an upper cover 13, and the surrounding wall 12 is provided on the bottom cover 11. The upper cover 13 covers the end of the surrounding wall 12 far from the bottom cover 11. In this manner, the housing 10 is formed by assembling a plurality of elements, which facilitates the manufacture of the housing 10.

The bottom cover 11 may be made of plastic. The wall 12 is substantially annular. The enclosure walls 12 may be made of a metal material, for example, the material of the enclosure walls 12 is an aluminum alloy, which can improve the heat dissipation efficiency of the enclosure walls 12. The upper cover 13 is covered on the surrounding wall 12. As such, the upper lid 13 may be used to support the blender cup 200.

In this embodiment, the upper lid 13 forms a sink 131, and the bottom of the stirring cup 200 is located in the sink 131. In this manner, the provision of the sink 131 allows the mixing cup 200 to be more stably supported on the upper cover 13. In the present embodiment, the cross section of the sink 131 is non-circular. For example, the cross section of the sink 131 may be in the shape of a rounded rectangle, trapezoid, or the like.

In the present embodiment, the base 100 includes a housing 10 and a circuit board 50, the circuit board 50 is accommodated in the housing 10, and the circuit board 50 is horizontally disposed. In this manner, the circuit board 50 is horizontally disposed such that the height of the housing 10 is low, and thus the height of the base 100 can be reduced.

The circuit board 50 may be used to control the operation of the motor 230. For example, the circuit board 50 may be used to control the input voltage and/or input current of the motor 230 to control the rotational speed of the motor 230.

In this embodiment, as mentioned above, since the motor 230 and the cup 210 are integrally disposed, rather than disposed in the base 100, the main heating electronic device in the base 100 is the circuit board 50, and the heat generated by the circuit board 50 is low, the surrounding wall 12 can satisfy the heat dissipation requirement without forming a heat dissipation hole or disposing a heat dissipation fan, and meanwhile, when the surrounding wall 12 is made of a metal material, the heat dissipation effect can be further improved. Therefore, the continuous closed structure is easy to manufacture, the cost is reduced, and meanwhile, the height of the base 100 can be reduced without adopting fan lamp heat dissipation equipment, so that the miniaturization of the base 100 is facilitated.

Referring to fig. 8(a) and 8(b), in the present embodiment, the cup 210 includes a bottom wall and a side wall extending upward from the bottom wall, the bottom wall is provided with a first coupling terminal 216 and a second coupling terminal 217, the sinking groove 131 is provided with a third coupling terminal 14 and a fourth coupling terminal 15, the first coupling terminal 216, the third coupling terminal 14, the second coupling terminal 217, and the fourth coupling terminal 15 are respectively coupled and electrically connected when the blender cup 200 is connected to the base 100, the first coupling terminal 216 and the second coupling terminal 217 are different in size, the third coupling terminal 14 and the fourth coupling terminal 15 are different in size, the first coupling terminal 216 and the third coupling terminal 14 are coupled to form a weak electric connection or a strong electric connection, and the second coupling terminal 217 and the fourth coupling terminal 15 are coupled to form a strong electric connection or a weak electric connection.

Thus, the mixing cup 200 is coupled to the base 100, and the upper coupler, i.e., the first and second coupling terminals, are inserted into the lower coupler, i.e., the third and fourth coupling terminals, respectively, to form a loop, so as to transmit electric energy and/or electric signals between the mixing cup 200 and the base 100, thereby controlling the operation or stop of the mixing machine 200. And furthermore, the two coupling terminals have different sizes so as to achieve the fool-proof effect.

Referring to fig. 9, in the present embodiment, the height ratio of the base 100 to the stirring cup 200 is less than or equal to 1/2. That is, the ratio H2/H1 of the height H2 of the base 100 to the height H1 of the blender cup 200 is less than or equal to 1/2. Preferably, the height ratio of the base 100 to the blender cup 200 is 1/5-1/2, such as 1/5, 1/4, 1/3, 1/2.

In this manner, the base 100 is smaller in height relative to the blender cup 200, such that the overall size of the food processor 300 is smaller, facilitating storage of the food processor 300.

In the related art, the height ratio of the base of the food processor to the stirring cup is approximately 1, that is, the height of the base is almost equal to that of the stirring cup, so that the food processor has a large overall volume and is not easy to store, and the user experience is reduced.

It should be noted that the height H2 of the chassis 100 is the largest dimension in the height direction of the chassis 100.
