Description

Technical Field

[0001] The present invention relates to the field of electric cooking machines with multi-mode control, and particularly to a multi-functional cooking machine with a motor placed on top and no support columns in a multi-mode control manner. Background Art

[0002] Current cooking machines generally include a main body and a mixing cup, and the main body drives a blade assembly in the mixing cup to rotate. Cooking machines generally adopt a design with the motor placed on top and generally do not have a planetary gearbox, so their torque is small and it is difficult to meet the user's demand for a larger torque. For example, a meat grinder with an electronic speed control function with the authorization announcement number CN212939451U, a cooking machine and its control method with the application publication number CN110609717A, and a capacitive low-noise stepless speed change chef machine with the authorization announcement number CN113647848B. Such machines require a very powerful motor to drive to ensure the use effect, and do not quite meet the increasingly stringent environmental protection requirements.

[0003] For cooking machines provided with a planetary gearbox, since the rotation speed cannot be adjusted, their functions are generally very few. For example, a food processor with a reverse stirring device with the authorization announcement number CN209733657U and a portable household fruit cooking machine with the authorization announcement number CN203314802U, which are difficult to meet the diverse use needs of users. There is also a type of machine using mechanical stepless speed change. Machines driven by belts and other means are not listed one by one because of their large volume, extremely high noise, and complex structure.

[0004] For cooking machines provided with a planetary gearbox, such as meat grinders, their function designs are also not many, generally about 3 functions, including meat grinding, dough kneading, and garlic peeling. And because this type of cooking machine generally only has a single gear or a double gear, when using other functions such as egg beating and milk frothing, the user experience is not good.

[0005] For some other multi-functional electric cooking machines with the motor placed on top, although they have a multi-gear control system, due to the absence of a planetary gearbox, they cannot be compatible in some scenarios where a larger torque is required. Therefore, their scope of use is greatly reduced, and the adjustment of gears is inconvenient, and the user experience is not good.

[0006] Therefore, it is necessary to improve the existing cooking machines. Summary of the Invention

[0007] The present invention aims to solve at least one of the problems existing in the related art to a certain extent. For this reason, an object of the present invention is to provide a multi-functional cooking machine with multi-mode control, which has convenient gear adjustment, can adjust the speed without stopping the machine, can be operated with one hand, has a large output torque, and provides a better user experience.

[0008] The above object is achieved by the following technical solutions:

[0036] Embodiment 1: As Figures 1 to 8 shown, this embodiment provides a multifunctional cooking machine with multi-mode control, including a main body 1 and a mixing cup 2.

The planetary gearbox 13 is arranged below the motor 12, and the rotating shaft of the motor 12 is in transmission connection with the planetary gearbox 13;

[0037] The mixing cup 2 includes a cup body 21 and a replaceable blade component 22 arranged inside the cup body 21. The main body 1 is detachably arranged on the cup body 21, and the planetary gearbox 13 is in transmission connection with the blade component 22. The motor 12 drives the blade component 22 to rotate through the planetary gearbox 13;

[0038] The main body 1 is placed on the upper port of the mixing cup 2, and the blade component 22 is movably connected to the planetary gearbox 13 built in the main body 1;

[0039] The speed change wheel 15 is exposed on the body of the main machine 1, and the speed change wheel 15 is transmission-connected and electrically connected to the circuit board 14 via a potentiometer knob 1401.

The output shaft of the motor 12 is transmission-connected to the planetary gear box 13, and the output shaft of the planetary gear box 13 can be movably connected to the blade assembly and can be movably connected to multiple tool combinations respectively.

[0040] The multi-function food processor with multi-mode control provided in this embodiment has convenient gear adjustment and better user experience.

[0041] Specifically, the variable speed wheel can be used to control and adjust the gear of the food processor with one hand, and the motor can be infinitely variable, which is convenient to use and adjust. At the same time, the electronic control infinitely variable speed solution is small in size and low in noise.

[0042] In addition, by equipping it with a planetary gearbox, a small-power motor can be used to achieve a larger torque, which extends the functions of the food processor. In addition to basic functions such as mincing meat, kneading dough, and peeling garlic, since it can achieve infinitely variable speeds, users can use this food processor to achieve more functions such as making milkshakes, beating eggs, making milk foam, and stirring milk powder. Users can set more containers that they want to match with different functions for their convenience. For example, for stirring milk powder, you can make a useful baby bottle that can be used directly after stirring.

[0043] Furthermore, the food processor of this embodiment can greatly improve the application scope of the product, and it has multiple functions and is easy to store.

[0044] In this embodiment, a base 16 is provided at the bottom of the housing 11 , and the planetary gear box 13 is fixed on the base 16 , which has a simple structure and a reasonable design, thereby facilitating the installation and fixation of the planetary gear box 13 .

[0045] Furthermore, a motor bracket 17 is provided on the base 16 for fixing the motor 12 , and the motor bracket 17 has a simple structure and a reasonable design, thereby facilitating the installation and fixing of the motor 12 .

[0046] Furthermore, a circuit board fixing plate 18 is provided on the motor bracket 17 for fixing the circuit board 14 , and has a simple structure and reasonable design, thereby facilitating the installation and fixing of the circuit board 14 .

[0047] In this embodiment, a speed-changing wheel fixing plate 19 is provided on the circuit board fixing plate 18 for mounting the speed-changing wheel 15 , which has a simple structure and a reasonable design, thereby facilitating the installation and fixing of the speed-changing wheel 15 .

[0048] An adjustment circuit and a protection circuit are provided on the control circuit board 14. The adjustment circuit includes a capacitor C1. One end of the capacitor C1 is connected to ACN, and the other end is connected in series with a resistor R2. Among them, the other end of the resistor R2 is connected in series with a slide rheostat RW1. A potentiometer 4 is connected to the slide rheostat RW1. The output end of the slide rheostat RW1 is connected in series with the drive motor 12. Of course, the other end of the drive motor 12 should be connected to ACL. The above acl is the AC live wire and acn is the AC neutral wire, so as to realize the power supply to the drive motor 12;

[0049] It also includes a bidirectional thyristor T1, and the bidirectional thyristor T1 is connected in parallel outside the capacitor C1, the resistor R2 and the slide rheostat RW1;

[0050] A bidirectional diode D1 is also connected in series at the other end of the capacitor C1, and the other end of the bidirectional diode D1 is connected to the G pole of the bidirectional thyristor T1 to be connected and conduct.

[0051] Specifically, in the present invention, the resistance value of the slide rheostat RW1 can be adjusted first through the potentiometer 1401 to charge the capacitor C1. For example, when the voltage difference of the capacitor C1 reaches 30V, the bidirectional trigger diode D1 will conduct, triggering the bidirectional thyristor T1 to conduct. At this time, the drive motor 12 works. By rotating the adjustable resistor RW1, the charging time of the capacitor C1 to 30V can be controlled;

[0052] When the capacitor C1 discharges until the voltage difference at both ends does not reach 30V, the bidirectional thyristor T1 is triggered to disconnect, and the capacitor C1 continues to charge. At the same time, no current passes through the drive motor 12. At this time, it works by the inertia of the previous cycle. In this way, the stepless start and stop of the motor 12 can be realized within a certain time, so as to control the power of the motor 12 and achieve a better stirring effect on the food;

[0053] The working principle of the present invention: By controlling the on and off time, the speed of the motor 12 can be adjusted arbitrarily from low speed to high speed, that is, the speed control of the drive motor 12 uses the on time of the control circuit to achieve different powers of the motor 12 per unit time.

[0054] In some embodiments, the protection circuit includes a resistor R1 and a capacitor C2. The resistor R1 and the capacitor C2 are connected in parallel outside the capacitor C1, the resistor R2 and the slide rheostat RW1. Among them, the resistor R1 and the capacitor C2 are connected in series. The resistor R1 and the capacitor C2 absorb interference in the bypass to prevent the circuit from receiving misjudgment signals. Similarly, the above resistor R2 plays a role in protecting the bidirectional trigger diode D1.

[0055] Further, the capacitance of the capacitor C1 is the same as that of the capacitor C2, and the resistance value of the resistor R1 is the same as that of the resistor R2. Of course, those skilled in the art know that in other embodiments, the capacitance of the capacitor C1 and the capacitor C2 may also be different, and the resistance values of the resistor R1 and the resistor R2 may also be different.

[0056] Furthermore, a thermistor NTC is connected in series between the capacitor C1 and the ACN. The thermistor NTC can prevent the impact from being too large and damaging the thyristor T1 at the moment of startup.

[0057] In summary, in the present invention, stepless speed regulation of the drive motor 12 is achieved through circuit control. First, the resistance value of the sliding rheostat RW1 can be adjusted by controlling the potentiometer 4. By controlling the magnitude of the current, the charging speed of the capacitor C1 can be determined. When the capacitor C1 is fully charged, the circuit is turned on, and thus the drive motor 12 starts to work. That is, by rotating the control potentiometer 1401 to adjust the magnitude of the sliding rheostat RW1, different conduction times of the voltage can be obtained. By controlling the on and off times, the speed of the potentiometer 1401 can be arbitrarily adjusted from low speed to high speed.

[0058] In this embodiment, the motor can be a DC motor or a series-wound motor. The circuit of the DC motor is as Figure 7 shown, and the circuit of the series-wound motor is as Figure 8 shown.

[0059] Further, a housing 3 is provided on the housing 11. The circuit board fixing plate 18, the circuit board 14, the speed change wheel fixing plate 19, and the speed change wheel 15 are arranged inside the housing 3. A top cover 4 is provided on the top of the housing 3. Its structure is simple, which can make the internal structure layout of the multifunctional cooking machine more reasonable, so as to achieve the purpose of improving the stability and reliability of product use.

[0060] Furthermore, a power cord 5 is provided on the base 16. Its structure is simple, which is convenient for connecting the multifunctional cooking machine and an external power supply.

[0061] In this embodiment, a safety switch 6 is provided on the base 16. The safety switch 6 is electrically connected to the circuit board 14. Its structure is simple. By providing the safety switch 6, the safety of product use is improved. In an emergency, the multifunctional cooking machine can be stopped in time through the safety switch 6, thereby avoiding accidents.

[0062] Further, the mixing cup 2 further includes a cup lid 23 and fixing screws 24. The cup lid 23 is detachably disposed on the top of the cup body 21, and the blade assembly 22 is installed in the cup body 21 through the fixing screws 24. The structure is simple, thus facilitating the installation and replacement of the blade assembly 22. Moreover, the blade assembly 22 adopts a replaceable design, and the user can replace different blade assemblies 22 according to usage requirements, which can meet more different usage needs of the user, is conducive to improving the user experience, and enhances the market competitiveness of the product.

[0063] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
