All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The base for bearing the cup body and the food processor provided by the utility model are described in detail with reference to the embodiments.

Referring to fig. 1 and 2, fig. 1 is an exploded view of a base for a load cup according to the present application; fig. 2 is a front view of the lower case shown in fig. 1. Base 1 is used for bearing cup 2 in this embodiment, and base 1 can be food processor base or broken wall machine base etc.. Base 1 is formed with and holds chamber 13, holds chamber 13 and divides into the motor and holds chamber 131 and control and hold chamber 132, and the motor holds and is provided with disc motor 141 in the chamber 131, and because of disc motor 141 height dimension is less, has reduced base 1 height, and then has reduced occupation space, is convenient for accomodate and is convenient for user operation. Wherein, set up control assembly 15 in control accommodation chamber 132, control assembly 15 is used for controlling whether base 1 works.

Because the disk motor 141 and the control assembly 15 inside the base 1 generate a large amount of heat during the operation, the stability and reliability of the disk motor 141 and the control assembly 15 may be affected by the large amount of heat accumulated in the accommodating cavity 13, and the service life of the base may be shortened. Therefore, in order to simultaneously take away the heat generated by the disk motor 141 and the control module 15, the first ventilation opening 121 is formed at the end of the cavity of the control accommodating cavity 132 away from the motor accommodating cavity 131, and the second ventilation opening 122 is formed at the end of the cavity of the motor accommodating cavity 131 away from the control accommodating cavity 132. Meanwhile, a baffle 16 is provided in the accommodating chamber 13, and a through hole 161 is provided on the baffle 16, the through hole 161 being used for wind flow to communicate the motor accommodating chamber 131 and the control accommodating chamber 132. That is, the through holes 161 formed through the first ventilation opening 121, the second ventilation opening 122 and the baffle 16 are matched with each other, so that the disc motor 141 and the control assembly 15 can be cooled simultaneously, and the cooling efficiency is improved.

In the heat dissipation process, one of the first and second ventilation openings 121 and 122 is used for air intake, and the other is used for ventilation. When the first ventilation opening 121 is used for air intake, the air flowing into the control accommodating cavity 132 from the first ventilation opening 121 enters the motor accommodating cavity 131 through the through hole 161; when the second ventilation opening 122 is used for air intake, the air flowing into the motor accommodating chamber 131 from the second ventilation opening 122 enters the control accommodating chamber 132 through the through hole 161. The first ventilation opening 121 or the second ventilation opening 122 is used for air intake or air outtake, and may be determined according to actual conditions. In addition, the number of the first ventilation openings 121 may be one or more, and the number of the second ventilation openings 122 may be one or more, which may be determined according to the actual situation.

The baffle 16 is arranged in the accommodating cavity 13 to divide the accommodating cavity 13 into a motor accommodating cavity 131 and a control accommodating cavity 132, so as to respectively mount the disc motor 141 and the control assembly 15, and meanwhile, the subsequent substances such as liquid and the like which carelessly enter the motor accommodating cavity 131 can be prevented from entering the control accommodating cavity 132 to influence the use stability and reliability of the control assembly 15; the disc motor 141 and the like can be prevented from being influenced in use stability and reliability due to the fact that the disc motor enters the control accommodating cavity 132 and enters the motor accommodating cavity 131 carelessly in the following process. The through hole 161 may be formed in the baffle 16, or may be formed by surrounding the baffle 16 and the accommodating chamber 13, which is not limited herein. The number of the through holes 161 may be one, two or more, wherein the number of the through holes 161 may be determined according to practical situations and is not limited herein.

In an embodiment, in order to reduce the size of the base 1, the motor accommodating chamber 131 and the control accommodating chamber 132 may be arranged side by side, wherein the arrangement direction of the motor accommodating chamber 131 and the control accommodating chamber 132 is parallel to the placing surface of the base 1, which not only increases the accommodating space in the base 1 for placing the disk motor 141 and the control assembly 15, but also reduces the overall height of the base 1.

Because the disk motor 141 is arranged in a disk shape, the control assembly 15 is arranged in a plane shape as a whole, and in order to increase the air flow area, the air reaches the corners in the motor accommodating cavity 131 and the control accommodating cavity 132 as much as possible. Both ends of this embodiment baffle 16 on first direction all are provided with through-hole 161, through all setting up through-hole 161 at baffle 16 both ends, can disperse the wind that enters into in holding chamber 13, and then enlarge wind flow area to further promote the radiating efficiency. The first direction is a direction indicated by a double-headed arrow X shown in fig. 2.

Specifically, in order to increase the air intake or the air output, two first vents 121 may be disposed at the end of the control accommodating cavity 132 away from the baffle 16, wherein the two first vents 121 are disposed at intervals in the first direction, so that air is simultaneously taken in or blown out from two sides of the control accommodating cavity 132, and further the heat dissipation effect is improved. In addition, the orthographic projection of the second ventilation opening 122 on the baffle 16 is located between the two through holes 161, so that the wind flow path is relatively short, the accommodating cavity 13 is uniformly covered, the heat dissipation effect is better, and the wind resistance is relatively small.

In practice, the control assembly 15 generates more heat than the disc motor 141 due to its. Therefore, in order to further improve the heat dissipation effect, in this embodiment, the two first vents 121 are both air inlets, which not only increases the air inlet volume, but also can perform heat dissipation processing on the control assembly 15 at the same time; then, the air enters the motor accommodating cavity 131 through the through holes 161 at the two ends of the baffle 16, and the disc motor 141 is arranged in a disc shape, so that the second air vent 122 is defined as an air outlet, wherein the orthographic projection of the second air vent 122 on the baffle 16 is positioned between the two through holes 161, so that the air can flow along the periphery of the disc motor 141, and the heat of the disc motor 141 is taken away, and the heat dissipation efficiency is improved; at the same time, the wind flow path is also made relatively short and covers the accommodation chamber 13 uniformly.

In order to make the internal structure of the base 1 more compact, in the process of installing the baffle 16 in the accommodating cavity 13, one end of the through hole 161 close to the middle of the baffle 16 is provided with an avoiding groove 1611, and the avoiding groove 1611 is used for avoiding partial structure or partial routing of the disc motor 141. The side of the through hole 161 away from the middle of the baffle 16 is provided with a flow channel 1612, and the flow channel 1612 is used for wind to pass through. In order to allow more wind to enter the motor accommodating chamber 131 and the control accommodating chamber 132 during the arrangement of the bypass groove 1611 and the circulation groove 1612, the depth of the circulation groove 1612 may be set to be lower than that of the bypass groove 1611 to allow more wind to pass therethrough.

The accommodating cavity 13 is also internally provided with a fan assembly 144, and the fan assembly 144 is used for accelerating the flow rate of wind, so that the heat dissipation effect in the base 1 is improved. Wherein, the fan assembly 144 can be disposed at the first ventilation opening 121 or the second ventilation opening 122. When the first ventilation opening 121 is used for air intake, the fan assembly 144 may be disposed at the second ventilation opening 122, and the fan assembly 144 is used for air intake, so that the air entering the first ventilation opening 121 discharges the heat of the control assembly 15 and the disc motor 141 from the second ventilation opening 122 relatively quickly. When the second ventilation opening 122 is used for air intake, the fan assembly 144 may be disposed at the first ventilation opening 121, and the fan assembly 144 is used for air intake, so that the air entering the second ventilation opening 122 discharges the heat of the disc motor 141 and the control assembly 15 from the first ventilation opening 121 relatively quickly.

In other embodiments, the fan assembly 144 may also blow air, and may be disposed at other positions as long as the air can be accelerated to flow at the first ventilation opening 121 and the second ventilation opening 122, which is not limited herein.

Specifically, the cross section of the drainage channel perpendicular to the drainage direction is the same as the shape of the upper drainage holes 115 and the lower drainage holes 172, that is, the cross section of the drainage channel is the same as the shape of the upper drainage holes 115 and the lower drainage holes 172, so that the drainage speed in the drainage channel is uniform.

Further, the upper drainage holes 115 and the lower drainage holes 172 are both drop-shaped, wherein the drop-shaped lower drainage holes 172 can reduce the self-tension of water and increase the drainage speed. Since the cross-section of the drain hole is the same as the shape of the upper and lower drain holes 115 and 172, the cross-sectional shape of the drain hole may be a drop shape. In other embodiments, the upper drainage holes 115 and the lower drainage holes 172 may have other shapes as long as the drainage speed can be increased, and are not limited herein.

Specifically, when the upper drain hole 115 and the lower drain hole 172 are distributed in a droplet shape, the long axis direction of the upper drain hole 115 and the lower drain hole 172 is set along the extending direction of the side wall of the groove 111, so that water enters the side wall of the drain channel along the side wall of the groove 111, the gravity of the water is increased, and the drainage speed is accelerated. The major axis direction is the direction of the straight line with the longest distance between the upper drainage hole 115 and the lower drainage hole 172.

Thus, the first circular hole 1721, the second circular hole 1722 and two tangent lines are arranged to form the drop-shaped lower drainage hole 172.

Specifically, a distance between a center of the first circular hole 1721 and a center of the second circular hole 1722 is greater than or equal to a sum of a radius of the first circular hole 1721 and a radius of the second circular hole 1722 to facilitate water drainage. The distance between the center of the first circular hole 1721 and the center of the second circular hole 1722 is related to the radius of the first circular hole 1721 and the radius of the second circular hole 1722, so the distance may be determined according to the radius of the first circular hole 1721 and the radius of the second circular hole 1722, and is not limited herein. First circular orifice 1721 and second circular orifice 1722 are tangentially disposed when a distance between a center of first circular orifice 1721 and a center of second circular orifice 1722 is equal to a sum of a radius of first circular orifice 1721 and a radius of second circular orifice 1722.

Further, the radius of the first circular holes 1721 is greater than or equal to 1mm, such as the radius of the first circular holes 1721 is 1mm, 2mm, 3mm, etc. The radius of the second circular apertures 1722 is greater than or equal to 2mm, such as the radius of the second circular apertures 1722 is 2mm, 3mm, 4mm, and so on. Assuming that the radius of the first circular hole 1721 is R1 and the radius of the second circular hole 1722 is R2, the distance between the center of the first circular hole 1721 and the center of the second circular hole 1722 is L, i.e., L ≧ R1+ R2, L can be 3mm, 4mm, 5mm, etc.

Since the disc motor 141 has a disc shape and a light and thin design, the disc motor 141 is small in size in the height direction. When the disk motor 141 is installed in the base 1 through the fixing member, the overall height dimension of the base 1 can be reduced, thereby reducing the overall height of the food processor. The disk motor 141 may be any disk motor 141 that is thin and light, as long as the size of the base 1 can be reduced. However, when a part of the disk motor 141 is used in the base 1, a part of noise is generated, and the cost is relatively high and the control is complicated.

Referring to fig. 12 and 13, fig. 12 is a schematic structural view of the disc motor shown in fig. 1; fig. 13 is a schematic view of the control principle of the disk motor shown in fig. 12. The disc motor 141 of the present embodiment includes a disc stator 81, an inverter 82, a first disc rotor 83, and a second disc rotor 84.

In the embodiment, the stator and the rotor are both disc type, and the disc type rotor covers the disc type stator, so that the light and thin design can be realized. Referring to fig. 14 and 15, fig. 14 is a schematic structural view of the disc stator 81 in the embodiment of the disc motor shown in fig. 12; fig. 15 is a schematic view of a structure in which a winding is provided on the disk stator shown in fig. 14.

Two corresponding rotors are respectively arranged through the two stator structures, so that a double-rotor motor is realized, and the disc type motor 141 is realized through corresponding control.

The first winding 851 is wound on the first stator structure 811, the second winding 852 is wound on the second stator structure 812, and the phase sequence of the first winding 851 is opposite to that of the second winding 852, so that the two windings can enable the corresponding rotors to rotate in different directions under the action of one inverter 82.

In the disc stator 81 of this embodiment, the first winding 851 wound on the first stator structure 811 is a concentrated winding, the second winding 852 wound on the second stator structure 812 is a distributed winding, or the first winding 851 is a distributed winding, the second winding 852 is a concentrated winding, or both of them are distributed windings and are concentrated windings. Since the two stator structures correspond to different rotation directions of the rotor, the first stator structure 811 and the second stator structure 812 are different in this embodiment for the convenience of distinction.

For example, if the first winding 851 is a concentrated winding and the second winding 852 is a distributed winding, the first stator structure 811 and the second stator structure 812 are different in that the stator yoke width of the first stator structure 811 corresponding to the concentrated winding is larger than the stator yoke width of the second stator structure 812 corresponding to the distributed winding.

Further, the first stator structure 811 and the second stator structure 812 may be designed as a single body, i.e., the disc stator 81 is a single body; or a split design, in which case, a magnetic barrier 813 may be disposed between the first stator structure 811 and the second stator structure 812 to isolate the first winding 851 and the second winding 852, so as to avoid mutual interference of magnetic fields generated by the two windings. Referring to fig. 16, fig. 16 is another schematic structural diagram of the disc stator in the embodiment of the disc motor shown in fig. 12.

The inverter 82 in this embodiment is connected in parallel with the first winding 851 and the second winding 852 to synchronously supply excitation currents to the first winding 851 and the second winding 852. Wherein the first windings 851 comprise a plurality of sets of first three-phase windings having the same phase sequence and the second windings 852 also comprise a plurality of sets of second three-phase windings having the same phase sequence, wherein the phase sequences of the first three-phase windings and the second three-phase windings are opposite.

The first three-phase winding comprises an A-phase winding, a B-phase winding and a C-phase winding which are sequentially arranged along a counterclockwise direction, and the corresponding second three-phase winding comprises an A-phase winding, a C-phase winding and a B-phase winding which are sequentially arranged along a counterclockwise direction.

In this regard, the first current output terminal 821, the second current output terminal 822, and the third current output terminal 823 of the inverter 82 are respectively connected to the three-phase windings. The a-phase windings of the first winding 851 and the second winding 852 are connected in parallel to the first current output terminal 821, the B-phase windings of the first winding 851 and the second winding 852 are connected in parallel to the second current output terminal 822, and the C-phase windings of the first winding 851 and the second winding 852 are connected in parallel to the third current output terminal 823.

With the inverter 82 providing the excitation current synchronously, the two windings can drive the two rotors to rotate in different directions respectively.

Wherein the disc squirrel cage rotor 860 is formed by squirrel cage bars 861 placed in a slotted rotor yoke 862; disc permanent magnet rotor 870 is formed by permanent magnets 871 affixed in permanent magnet rotor yoke 872.

The first disc rotor 83 is arranged on one side of the first stator structure 811 and rotates in a first direction by the first windings 851, and the second disc rotor 84 is arranged on one side of the second stator structure 812 and rotates in a second direction by the second windings 852, the first direction being opposite to the second direction.

In this embodiment, the first disc rotor 83 and the second disc rotor 84 are respectively disposed on two sides of the disc stator 81, so that the problem of unbalanced magnetic tension on one side is avoided. Further, the disc stator 81, the first disc rotor 83 and the second disc rotor 84 are coaxially arranged, so that the problem of unbalanced magnetic tension can be reduced.

One of the first disc rotor 83 and the second disc rotor 84 is a first disc squirrel cage rotor, and the other is a second disc squirrel cage rotor, a disc permanent magnet rotor, or a disc reluctance rotor. The inverter 82 performs closed loop vector control on the second disc squirrel cage rotor, the disc permanent magnet rotor, or the disc reluctance rotor, while the first disc squirrel cage rotor automatically operates in a V/F open loop control mode.

Specifically, the closed-loop vector control is to control the rotation speed and the torque of the motor respectively, and can generate output voltages matched with different loads according to the received feedback signals. The V/F open loop control means that the ratio of the output voltage V to the operating frequency F is a constant value, and it cannot receive a feedback signal, so its output voltage is not affected by the load.

In the present embodiment, the squirrel cage rotor generally corresponds to the distributed windings, and the concentrated windings generally correspond to the permanent magnet rotor or the reluctance rotor. Therefore, one setting manner in this embodiment is: the first stator structure 811 is provided with a concentrated winding, and the first disc rotor 83 is a disc permanent magnet rotor; distributed windings are provided on the second stator structure 812 and the second disc rotor 84 is a disc squirrel cage rotor. The inverter 82 performs closed-loop vector control on the first disc rotor 83, so that the second disc rotor 84 automatically operates in a V/F open-loop control mode.

In the embodiment of the present application, one of the first disc rotor 83 and the second disc rotor 84 is set as the first squirrel cage rotor, so that the disadvantage that a dual-permanent-magnet rotor, a dual-reluctance rotor, or a dual-rotor motor with permanent magnets and reluctance matched with each other must be controlled by two sets of inverters can be avoided, and the control of the two rotors is realized by one set of inverters.

Specifically, a power supply (not shown in the figure) supplies power to the first winding 851 and the second winding 852 simultaneously through the inverter 82, the first winding 851 generates a first magnetic field under the action of excitation current, the disc-type permanent magnet rotor is driven to rotate in a first direction, for example, the first direction can be a clockwise direction in the embodiment, the voltage and the frequency of the first winding 851 gradually increase, the rotating speed of the disc-type permanent magnet rotor gradually increases, and the inverter 82 precisely controls the speed or the torque of the disc-type permanent magnet rotor by precisely controlling the output voltage, the output current and the output frequency of the first winding 851, so as to realize the closed-loop vector control of the first winding 851.

Meanwhile, the second winding 852 which is connected in parallel with the first winding 851 and the inverter 82 also receives the excitation current to generate a second magnetic field, and the phase sequence of the second winding 852 is opposite to that of the first winding 851, so that the disk-type squirrel cage rotor is driven by the second winding 852 to rotate in a second direction which is opposite to the first direction, for example, the second direction may be a counterclockwise direction in the embodiment, the voltage and the frequency of the second winding 852 are gradually increased, and the rotation speed of the disk-type squirrel cage rotor is gradually increased; when the inverter 82 realizes the closed-loop vector control on the first winding 851, the ratio of the output voltage to the output frequency is a constant value, so that the disc type squirrel-cage rotor can automatically operate in a V/F open-loop control mode. When the load of the disc type squirrel cage rotor is large, the disc type squirrel cage rotor is controlled by the disc type squirrel cage rotor, the running rotating speed of the disc type squirrel cage rotor is lower than the synchronous rotating speed of a magnetic field, and slip is generated, so that asynchronous electromagnetic torque matched with the load is generated, and the step-out risk is avoided.

The disc type motor 141 provided by the embodiment of the application is provided with two sets of matched windings and rotors, and the two sets of windings are synchronously controlled by one set of the inverters 82, so that an electric brush can be omitted, noise is reduced, the service life of the motor is prolonged, meanwhile, the cost is lower due to the fact that two sets of the inverters 82 are not needed, and the control is simpler.
