Description

Technical Field

[0001] This invention relates to a food processor. Background Technology

[0002] Existing food processors generally include a base and a blending cup mounted on the base. The base contains a drive motor, and the blending cup contains a blending blade assembly. The base has a lower clutch assembly connected to the drive motor, and the bottom of the blending cup has an upper clutch assembly connected to the blending blade assembly. When the blending cup is placed on the base, the upper clutch assembly at the bottom of the blending cup is connected to the lower clutch assembly on the base. When the drive motor starts running, it drives the blending blade assembly to rotate through the lower and upper clutch assemblies.

[0003] Most food processors currently available do not have a function to detect and lock the blade assembly in place after it is installed. If the blade assembly is not locked in place, the liquid inside the food processor may leak out from the blade assembly mounting hole when the machine starts operating, due to vibration.

[0004] Chinese patent number ZL CN201710761421.X discloses a mixing container for a motor-driven kitchen appliance. The container base plate (3) or support member (5) is provided with a locking element (6) subjected to a spring force by a spring element (36). The locking element (6) prevents the stirrer (4) from being fixed in a locked position by means of a corresponding abutment element (7) on the support member (5) or the container base plate (3), thereby preventing the stirrer (4) from being transferred to a fixed release position by the spring force. The locking element (6) has a stop claw (10) oscillatingly arranged on the container base plate (3), which can oscillate around an oscillation axis (11) perpendicular to the container base plate (3). This structure provides a stop mechanism for the stirrer (4) to operate even when not fully installed, thanks to the locking element (6). However, this solution is purely structural, lacking electronic control identification and user prompts. When the support (5) does not lock the stirrer (4) in place, the locking element (6) can prevent the upper coupler pin from inserting into the lower coupler. When the support (5) locks the stirrer (4) in place, the locking element (6) is released and no longer prevents the pin from inserting into the lower coupler. The above structure has the problem that it is inconvenient to clean the components at the bottom of the container when they are dirty. Also, when the support (5) is installed in place but the stop claw (10) of the locking element (6) does not swing (i.e., the spring force is insufficient or the spring is stuck), the locking element (6) cannot prevent the upper coupler pin from inserting into the lower coupler. In this case, the user has to disassemble the support (5) and reinstall the stirrer (4). Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a food processor that can effectively identify whether the mixing blade assembly is properly installed and locked.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a food processor, including a base and a food processor cup disposed on the base, a drive motor is provided inside the base, a lower clutch assembly connected to the drive motor is provided on the base, a through hole for installing a mixing blade assembly is provided at the bottom of the food processor cup, the mixing blade assembly passes through the through hole and extends into the food processor cup, and a blade assembly fixing seat is disposed on the outside of the bottom of the food processor cup and connected to the bottom of the food processor cup, the blade assembly fixing seat is used to lock and fix the mixing blade assembly to the bottom of the food processor cup, characterized in that: an electronic identification element is provided on the base, and an identification element is provided on the blade assembly fixing seat, the electronic identification element is positioned on the base such that: when the blade assembly fixing seat locks and fixes the mixing blade assembly to the bottom of the food processor cup, the electronic identification element can identify a signal, and when the blade assembly fixing seat fails to lock and fix the mixing blade assembly to the bottom of the food processor cup, the electronic identification element cannot identify a signal.

[0007] As a preferred embodiment, the electrical identification element is a Hall switch, and the identified element is a magnet. When the blade assembly fixing seat locks and fixes the stirring blade assembly to the bottom of the blending cup, the electrical identification element and the identified element are arranged vertically in a vertically corresponding manner, and at this time the electrical identification element can identify the signal.

[0008] As a preferred embodiment, the electronic identification element is disposed at the lower end of the tool assembly fixing seat near the machine base; the identification element is disposed inside the machine base adjacent to the tool assembly fixing seat.

[0009] As a preferred embodiment, the vertical distance between the electronic identification element and the identified element is less than or equal to 20 mm.

[0010] As a preferred embodiment, the magnetic induction intensity of the magnet of the identified element is greater than or equal to 2000 Gs, and the horizontal area is greater than or equal to 0.5 cm². 2 .

[0011] As a preferred embodiment, a groove is provided on the lower end face of the tool assembly mounting base, and the identified component is installed in the groove and sealed with glue.

[0012] To improve safety, the base is provided with a lower coupler assembly, and the bottom of the blending cup is connected to an upper coupler assembly. The upper coupler assembly is provided with a metal pin that can be inserted into the lower coupler assembly. The bottom of the blending cup is also connected to a pin assembly, which includes a track frame and a pin that is movably mounted on the track frame. The end of the pin is connected to a pin magnet, and the pin magnet can attract the metal pin.

[0013] When the blade assembly holder fails to lock and secure the blending blade assembly to the bottom of the blending cup, the pin magnet at the end of the pin attracts the metal pin, causing the pin to pop out. At this time, when the blending cup is placed on the base, the pin will prevent the metal pin from inserting into the lower coupler assembly.

[0014] When the blade assembly holder locks and secures the blending blade assembly to the bottom of the blending cup, the magnet on the blade assembly holder attracts the pin magnet. The magnetic attraction between the magnet and the pin magnet is greater than the magnetic attraction between the metal pin and the pin magnet. The pin retracts into the track frame. At this time, when the blending cup is placed on the base, the pin will not prevent the metal pin from being inserted into the lower coupler assembly.

[0015] This solution combines electrical signal recognition to ensure the stirring blade assembly is properly assembled and locked, with physical recognition added for double protection.

[0016] The pin assembly also includes a spring acting on the pin, the spring having an elastic force that ejects the pin.

[0017] As an improvement, one end of the blade assembly fixing seat is movably inserted into the through hole, and the remaining part is located on the outer side of the bottom of the blending cup. The blade assembly fixing seat can rotate around the center of the through hole. The blade assembly fixing seat has a mounting hole, through which the stirring blade assembly passes and extends into the blending cup. The outer wall of the stirring blade assembly connected to the mounting hole has at least two spaced protruding locking parts. The blade assembly fixing seat has a slot on the inner wall of the mounting hole that allows the protruding locking parts to pass through. The blade assembly fixing seat also has a groove on the inner wall of the mounting hole that communicates with the slot. When the stirring blade assembly passes through the mounting hole on the blade assembly fixing seat, the protruding locking parts pass through the slot. At this time, the blade assembly fixing seat fails to lock and fix the stirring blade assembly to the bottom of the blending cup. When the blade assembly fixing seat is rotated and the protruding locking parts are rotated into the groove, the blade assembly fixing seat locks and fixes the stirring blade assembly to the bottom of the blending cup.

[0018] As an improvement, the slot near the opening is an arc-shaped surface or a slope.

[0019] The bayonet and the slot can be directly mounted on the tool assembly mounting base. A ring-shaped buckle is fixed inside the mounting hole of the tool assembly mounting base, and the bayonet and the slot can also be mounted on the inner wall of the ring-shaped buckle. A spring washer is provided between the ring-shaped buckle and the tool assembly mounting base.

[0020] The base is equipped with a control circuit board, and the electrical identification element is electrically connected to the control circuit board. The control circuit board can determine whether the blade assembly fixing seat has locked and fixed the mixing blade assembly to the bottom of the food processor cup based on the identification signal of the electrical identification element.

[0021] The base is equipped with a display component that is electrically connected to the control circuit board. The control circuit board displays whether the blade assembly fixing seat locks and fixes the mixing blade assembly to the bottom of the food processor cup through the display component.

[0022] If the control circuit board determines that the blade holder is not locking and securing the blending blade assembly to the bottom of the blending cup, it will issue an alarm via the display component and display a warning message, reminding the user to reinstall the blade holder to ensure that it locks and secures the blending blade assembly to the bottom of the blending cup.

[0023] Compared with the prior art, the advantages of the present invention are as follows: by providing an electronic identification element on the base and an identification element on the blade assembly fixing seat, the electronic identification element can only identify the signal when the blade assembly fixing seat locks and fixes the mixing blade assembly to the bottom of the blending cup. When the blade assembly fixing seat fails to lock and fix the mixing blade assembly to the bottom of the blending cup, the electronic identification element cannot identify the signal. Compared with the purely structural locking elements in the prior art, the electronic identification element can effectively identify whether the mixing blade assembly is assembled and locked in place, and has a high success rate of identification without misjudgment.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example

[0033] like Figure 1 , 2 The food processor shown includes a base 1 and a food processor cup 2 mounted on the base. A drive motor 11 is located inside the base 1. The base 1 also has a lower clutch assembly 12 and a lower coupler assembly connected to the drive motor 11. The bottom of the food processor cup 2 has a through hole 21 for mounting a blade assembly. A blade assembly 3 passes through the through hole 21 and extends into the food processor cup 2. The lower end of the blade assembly 3 is connected to an upper clutch assembly 32. The upper clutch assembly 32 is capable of drivingly connecting with the lower clutch assembly 12. The bottom of the food processor cup 2 is connected to the upper coupler assembly 22, which has a mechanism for inserting into the lower coupler assembly. The metal pin 221; a blade assembly fixing seat 4 connected to the bottom of the blending cup is provided on the outer side of the bottom of the blending cup. The blade assembly fixing seat 4 is used to lock and fix the blending blade assembly 3 to the bottom of the blending cup 1. An electronic identification element 5 is provided on the base 1. An identification element 6 is provided on the blade assembly fixing seat 4. The position of the electronic identification element 5 on the base 1 satisfies the following condition: when the blade assembly fixing seat 4 locks and fixes the blending blade assembly 3 to the bottom of the blending cup 2, the electronic identification element 5 can identify the signal; when the blade assembly fixing seat 4 fails to lock and fix the blending blade assembly 3 to the bottom of the blending cup 2, the electronic identification element 5 cannot identify the signal.

[0034] In this embodiment, the electrical identification element 5 is a Hall switch, and the identified element 6 is a magnet. A groove is provided on the lower end face of the blade assembly fixing seat 4, and the identified element 6 is installed in the groove and sealed with glue. When the blade assembly fixing seat 4 locks the stirring blade assembly 3 and fixes it to the bottom of the blending cup 2, the electrical identification element 5 and the identified element 6 are vertically aligned, and the electrical identification element can detect the signal. The vertical distance between the electrical identification element 5 and the identified element 6 is less than or equal to 20mm. The magnetic induction intensity of the identified element magnet 6 is greater than or equal to 2000Gs, and the horizontal area is greater than or equal to 0.5cm². 2 .

[0035] In this embodiment, one end of the blade assembly fixing base 4 is movably inserted into the through hole 21 at the bottom of the cooking cup 2, and the remaining part is located on the outer side of the bottom of the cooking cup 2, and the blade assembly fixing base 4 can rotate around the center of the through hole 21; see also Figure 3 , 6As shown, the blade assembly mounting base 4 has a mounting hole 41, and an annular screw fastener 7 is fixed inside the mounting hole 41; the stirring blade assembly 3 passes through the mounting hole 41 and the annular screw fastener 7 on the blade assembly mounting base and extends into the blending cup; the outer wall of the stirring blade assembly 3, which connects to the mounting hole 41 and the annular screw fastener 7, has three spaced protruding locking parts 31, see [reference]. Figure 4 As shown; the inner wall of the annular snap fastener 7 has three slots 71 at corresponding positions, each allowing a protruding latching part 31 to pass through. The inner wall of the annular snap fastener 7 also has three slots 72 that communicate with the three slots respectively. The slots 72 are arc-shaped near the slots 71. See Figure 5 As shown; a spring washer 8 is provided between the annular buckle 7 and the blade assembly fixing seat 4; when the stirring blade assembly 3 passes through the mounting hole 41 and the annular buckle 7 on the blade assembly fixing seat 4, the three protruding locking parts 31 pass through the three slots 71 respectively. At this time, the blade assembly fixing seat 4 fails to lock and fix the stirring blade assembly 3 to the bottom of the cooking cup; when the blade assembly fixing seat 4 is rotated and the three protruding locking parts 31 are rotated into the three slots 72 respectively, the blade assembly fixing seat 4 locks and fixes the stirring blade assembly 3 to the bottom of the cooking cup 2.

[0036] In addition, in this embodiment, the base 1 is equipped with a control circuit board. The electrical identification element 5 is electrically connected to the control circuit board. The control circuit board can determine whether the blade assembly holder has locked and fixed the mixing blade assembly to the bottom of the blending cup based on the identification signal of the electrical identification element 5. The base 1 is equipped with a display component 9 electrically connected to the control circuit board. The control circuit board displays whether the blade assembly holder has locked and fixed the mixing blade assembly to the bottom of the blending cup through the display component 9. If the control circuit board determines that the blade assembly holder has not locked and fixed the mixing blade assembly to the bottom of the blending cup, it will sound an alarm through the display component and pop up a warning message to remind the user to reinstall the blade assembly holder so that the blade assembly holder locks and fixes the mixing blade assembly to the bottom of the blending cup. Example

[0037] Unlike Embodiment 1, the bottom of the cooking cup 2 is also connected to a pin assembly, which includes a track frame 101, a pin 102 movably mounted on the track frame, and a spring 103 mounted in the track frame 101 and acting on the pin 102. The spring 103 has an elastic force that pops the pin 101 out. The end of the pin 101 is connected to a pin magnet 104, which can attract the metal pin 221.

[0038] When the blade assembly holder 4 fails to lock and secure the mixing blade assembly 3 to the bottom 2 of the blending cup, the pin magnet 104 at the end of the pin 101 attracts the metal pin 221, and the pin 102 pops out. At this time, when the blending cup 2 is placed on the base 1, the pin 102 will prevent the metal pin 221 from inserting into the lower coupler assembly. (See below) Figure 7 As shown.

[0039] When the blade assembly holder 4 locks and secures the mixing blade assembly 3 to the bottom of the blending cup 2, the identified element 6 (i.e., the magnet) on the blade assembly holder 4 attracts the pin magnet 104. The magnetic attraction between the identified element 6 and the pin magnet 104 is greater than the magnetic attraction between the metal pin 221 and the pin magnet 104, and can overcome the elastic force of the spring 103. At this time, the pin 102 retracts into the track frame 101. When the blending cup 2 is placed on the base 1, the pin 102 will not prevent the metal pin 221 from inserting into the lower coupler assembly. See [link to relevant documentation]. Figure 8 As shown.
