Description

Technical Field

[0001] The utility model relates to the field of food processing, in particular to a food processing machine cup body and a food processing machine. Background Art

[0002] With the improvement of living standards, food processors with heating and pulverizing functions are becoming increasingly popular among consumers. These food processors use a brushless motor to drive the blades to pulverize ingredients. The brushless motor is integrated with the food container, with the motor output shaft directly connected to the blades. This food processor offers advantages such as a simple and reliable transmission structure and low transmission noise.

[0003] In existing food processors, a motor protector can be installed to improve the safety of the food processor to protect the motor. For example, the utility model patent application number 201220710428.1 discloses a soymilk machine motor protector, comprising: a top cover 200 having a top cover thickness; a base 300 having a base thickness, the base 300 cooperating with the top cover 200 to form a protector housing, the protector housing having a storage space therein, the storage space having a longitudinal direction and a transverse direction, the span of the storage space in the longitudinal direction being greater than the span of the storage space in the transverse direction; and a motor protector body 400 having an outer shape matching the storage space and being accommodated in the storage space. A reinforcing rib 310 is provided above the bottom plate of the base 300 for strengthening and heat insulation, and the bottom of the motor protector body 400 is directly supported by the reinforcing rib 310. Installing the soymilk machine motor protector in the soymilk machine can ensure that the protector must cut off the circuit before the user finishes squeezing soymilk for the fifth time in a row, thereby preventing the soymilk machine from overheating.

[0004] However, existing food processors offer an increasing number of functions, such as heating, temperature detection, and overflow prevention. These functions, including motor protection, rely on pins within the food processor. This increasing number of functions requires more pins, and the increased number of pins also increases costs.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention but merely represents selected embodiments of the present invention.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0027] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0028] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0029] The embodiment of the present invention provides a food processing machine cup and a food processing machine, wherein the food processing machine cup can be a part of the food processing machine, and the food processing machine cup cooperates with other parts of the food processing machine to realize the function of automatic food processing. Figure 1As shown, the food processor provided by the embodiment of the present invention may specifically include: a machine body 10 and a food processor cup body 20 provided on the machine body 10. The food processor cup body 20 is the food processor cup body provided by some other embodiments of the present invention.

[0030] Further, such as Figure 2 、 Figure 3 As shown, the embodiment of the present invention provides a food processing machine cup body 20, which specifically includes a main body 21 and a brushless motor 22, a coupler 23, and a brushless motor protector 24 ( Figure 2 ), and several functional components 25. The machine body 10 may also include a brushless motor control circuit board and a coupler connecting the brushless motor control circuit board. When the food processor cup 20 is mounted on the machine body 10, the coupler 23 on the machine body 10 and the coupler 23 on the food processor cup 20 are coupled to each other. When the food processor cup 20 is removed from the machine body 10, the coupler 23 on the machine body 10 and the coupler 23 on the food processor cup 20 are separated from each other. The brushless motor 22 is electrically connected to the coupler 23 on the food processor cup 20, thereby enabling the connection between the brushless motor control circuit board and the brushless motor 22 and the brushless motor control circuit board to power and control the brushless motor 22 through the coupler 23 on the machine body 10 and the coupler 23 on the food processor cup 20.

[0031] Among them, the brushless motor protector 24 can be specifically a protection device used to stop the brushless motor from running when the brushless motor is working abnormally. It protects the brushless motor by stopping the abnormal working state of the brushless motor; the functional device 25 can be an electronic device that realizes the corresponding food processing function.

[0032] Specifically, such as Figure 1 As shown, the main body 21 may include, for example, a cup body 211 and a cup cover 212 disposed on the cup body 211. Corresponding to such a food processor cup body, the functional device 25 may include, for example, a cup cover detection switch 251 for detecting the opening and closing status of the cup cover.

[0033] Alternatively, in some embodiments of the present invention, the main body 21 may further include a heating plate 213 for generating heat during food processing. Corresponding to the food processor cup provided with the heating plate, the functional device 25 may include, for example, a heating plate thermostat 252 for controlling the temperature of the heating plate, a heating plate fuse 253 for monitoring the temperature of the heating plate and shutting down the heating plate when the temperature exceeds a maximum temperature threshold, and a temperature sensor 254 for detecting the temperature of the brushless motor and the heating plate.

[0034] It can be understood that the aforementioned cup lid detection switch 251, heating plate thermostat 252, heating plate fuse 253, and temperature sensor 254 are only some specific examples of the functional device 25 in some embodiments of the present invention. In some other embodiments of the present invention, the functional device 25 can also be, for example, a liquid level sensor for realizing the slurry liquid level detection function, an anti-overflow sensor for realizing the slurry overflow prevention function, etc.

[0035] Further, such as Figure 4 As shown, the coupler 23 includes a plurality of pins 231, and the brushless motor 22 and several functional devices 25 are electrically connected to different pins 231. Among them, the brushless motor protector 24 is connected in series with any functional device 25 and then electrically connected to the pin 231. Specifically, as Figure 3 As shown, the brushless motor protector 24 is connected in series with any functional device 25 and then electrically connected to the pin 231 . For example, the brushless motor protector 24 is connected in series with the cup cover detection switch 251 and then electrically connected to the pin 231 .

[0036] The brushless motor protector 24 is connected in series with any functional device 25 and then electrically connected to the pin 231, which can be specifically as follows: Figure 3 The cup cover detection switch 251 is shown in a form in which one end is electrically connected to the pin 231 and the other end is electrically connected to the brushless motor protector 24. In some other embodiments of the present invention, the brushless motor protector 24 is connected in series with any functional device 25 and then electrically connected to the pin 231. Alternatively, one end of the brushless motor protector 24 is electrically connected to the pin 231 and the other end is electrically connected to the cup cover detection switch 251.

[0037] It can be understood that the aforementioned brushless motor protector 24 is connected in series with any functional device 25 and then electrically connected to the pin 231. Specifically, the brushless motor protector 24 is connected in series with the cup cover detection switch 251 and then electrically connected to the pin 231. This is only an example of the specific structure in this embodiment. In some other embodiments of the present utility model, the brushless motor protector 24 is connected in series with any functional device 25 and then electrically connected to the pin 231. For example, it can also be as follows Figure 5 As shown, the brushless motor protector 24 is connected in series with the heating plate thermostat 252 and then electrically connected to the pin 231; or as shown in FIG. Figure 6 As shown, the brushless motor protector 24 is connected in series with the heating disk fuse 253 and then electrically connected to the pin 231; or the brushless motor protector 24 is connected in series with the temperature sensor 254 and then electrically connected to the pin 231, etc., and other specific implementation methods.

[0038] Specifically, in different embodiments of the present invention, different types of brushless motor protectors 24 can be provided depending on the specific model and type of food processor. For example, in this embodiment, the brushless motor protector 24 can be a snap protector. A snap protector uses a fixed-temperature bimetallic disc as a heat-sensitive component. When the ambient temperature increases or decreases, the heat generated is transferred to the bimetallic disc. When the set operating temperature is reached, the protector rapidly actuates, causing the contacts to open or close through mechanical action, thereby connecting or disconnecting the circuit and controlling the circuit. The bimetallic disc, acting as a temperature-sensing element (using a cover to transfer heat), instantly generates a snap action when the temperature rises (or drops) to the operating temperature. This action is transmitted by a ceramic actuating rod to the elastic component—the moving contact bracket. The moving contact and the fixed contact are riveted to the moving contact bracket and the horn, respectively. When the moving contact bracket is pushed by the actuating rod, the moving contact and the fixed contact separate, thereby disconnecting the circuit. When the temperature drops to the recovery temperature of the disc-shaped bimetallic strip, the bimetallic strip instantly returns to its original shape, the pressure on the actuating rod is eliminated, and the moving and fixed contacts are reconnected. The brushless motor protector 24 is configured as a snap-action protector. When the temperature sensed by the snap-action protector rises above a set threshold temperature during the operation of the brushless motor, the brushless motor is deemed to be in an abnormal operating state. At this time, the contacts inside the snap-action protector are disconnected, disconnecting the circuit connected to the brushless motor and causing the brushless motor to stop operating, thereby protecting the brushless motor. When the temperature of the brushless motor drops below the set threshold temperature, the snap-action protector can reconnect the circuit connected to the brushless motor and allow the brushless motor to operate again. This eliminates the need for the user to perform additional replacement or debugging of the brushless motor protector 24, making it more convenient for ordinary users who are not proficient in circuit maintenance and replacement.

[0039] It should be understood that the aforementioned brushless motor protector 24 being a snap-action protector is merely a specific example of the brushless motor protector 24 in this embodiment. In another embodiment of the present invention, the brushless motor protector 24 may also be a PTC thermistor. PTC stands for Positive Temperature Coefficient, meaning positive temperature coefficient. It generally refers to semiconductor materials or components with a large positive temperature coefficient, typically a thermistor, also known as a PTC thermistor. A protector equipped with a PTC thermistor is a PTC thermistor. A PTC thermistor is a temperature-sensitive semiconductor resistor. Above a certain temperature (the Curie temperature), its resistance increases in a step-like manner as the temperature rises. When the circuit is operating normally, the thermistor's temperature is close to room temperature and its resistance is very low. Connecting it in series with the circuit will not hinder current flow. However, when the circuit malfunctions and overcurrent occurs, the thermistor's temperature rises due to increased heat generation. When the temperature exceeds the switch temperature, the resistance suddenly increases dramatically, rapidly reducing the current in the circuit to a safe value. This is the current change during the thermistor's protection of an AC circuit. Since polymer PTC thermistors are easy to design, their sensitivity to temperature can be adjusted by changing their switching temperature, making them suitable for temperature control with high precision in different operating environments. Similar to the aforementioned brushless motor protector 24 being a sudden-action protector, setting the brushless motor protector 24 as a PTC thermistor can also disconnect the brushless motor when it is working abnormally and reconnect it after the brushless motor recovers. Therefore, there is no need for the user to perform additional replacement or debugging of the brushless motor protector 24, making it more convenient for ordinary users who are not proficient in circuit maintenance and replacement to use; in addition, due to the adjustable sensitivity of the PTC thermistor, setting the brushless motor protector 24 as a PTC thermistor can be more widely applicable to different types of brushless motors and different usage scenarios of brushless motors, providing precise protection for brushless motors of different types and in different usage scenarios, thereby improving the accuracy of protection for brushless motors.

[0040] In addition, in some other embodiments of the present invention, the brushless motor protector 24 can also be, for example, a thermal fuse. A thermal fuse is an electrical device that generates heat to melt a fuse element and disconnect the circuit when the current exceeds a set current threshold. Common thermal fuses are fuses. They can melt when the brushless motor is operating abnormally, thereby disconnecting the circuit connection of the brushless motor, causing the brushless motor to stop operating and protecting the brushless motor. Because thermal fuses are relatively low in cost and their melting process is less affected by other factors, using a thermal fuse as the brushless motor protector is safer and less expensive.

[0041] In this embodiment, the brushless motor may be a three-phase brushless motor, such as a permanent magnet brushless DC motor. Using a three-phase brushless motor can provide the food processor with lower noise, higher power density, and a longer service life. It should be understood that the aforementioned brushless motor being a permanent magnet brushless DC motor is merely an example of a brushless motor in this embodiment. In other embodiments of the present invention, the brushless motor 22 may also be another type and model of brushless motor, such as a permanent magnet synchronous motor.

[0042] Further, such as Figure 3 As shown, the number of pins 231 of the coupler 23 can be eight. Figure 4 As shown, three of the eight pins 231 are electrically connected to the brushless motor 22, and the other five pins are electrically connected to the cup cover detection switch 251, the heating plate thermostat 252, the heating plate fuse 253, the temperature sensor 254, and the ground terminal GND respectively.

[0043] Compared with the prior art, in the food processing machine cup body provided by the embodiment of the present invention, in the food processing machine cup body 20 including multiple functional devices 25, the brushless motor protector 24 is connected in series with any functional device 25 and then electrically connected to the pin 231 of the coupler 23, that is, the brushless motor protector 24 and at least one functional device 24 are simultaneously connected to a single pin 231 of the coupler 23, thereby realizing the reuse of the pin 231 of the coupler 23, thereby realizing the connection and installation of the brushless motor protector 24 without increasing the number of pins of the coupler 23, solving the problem of insufficient number of coupler pins 231 and inability to install the brushless motor protector 24; and after the brushless motor protector 24 is connected and installed, the brushless motor protector 24 installed in the food processing machine cup body 20 can play a role in protecting the brushless motor 22, thereby improving the operating safety and service life of the brushless motor 22.

[0044] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
