Description

Technical Field

[0001] The invention relates to a pot cover assembly and a food processor using the pot cover assembly. Background Art

[0002] With the development of society, people's pursuit of quality of life is constantly improving. More people choose to cook their own food, and food processors are also popular in the market. Food processors combine multiple functions such as cooking, juicing, grinding, and stirring. They can not only cook dishes, but also squeeze juice and stir meat stuffing. The cup body and the machine base are detachable for easy storage. It has the characteristics of one machine with multiple uses and easy to use. The lid of the existing food processor needs to be opened and closed by the user. If a food processor is used to cook dishes, when the juice needs to be collected, the lid cannot be opened automatically to allow the water vapor to escape, resulting in too much soup in the dish, affecting the quality and taste of the dish. When it is necessary to add ingredients, the user must open the lid by himself, which causes artificial inconvenience.

[0003] To this end, the Chinese patent application with application number 201910567755.2 discloses a food processor that can automatically open and close the lid of the pot, which includes a machine base, a pot body with an opening on the top of the machine base, a pot lid arranged at the opening of the pot body, and the pot lid is connected to a flip cover arm, one end of the flip cover arm is rotatably connected to the machine base, and a driving mechanism is provided in the machine base that can drive the flip cover arm to rotate so as to drive the pot lid to open from the opening of the pot body or drive the pot lid to be set at the opening of the pot body. The driving mechanism can drive the flip cover arm to rotate at different angles, so that the pot lid opens at different angles, realizing the functions of collecting juice and adding dishes. However, in this structure, during the process of opening the pot lid, the entire pot lid is in an open state as a whole. If the stirring component or knife group in the food processor is still rotating at a high speed, there is a risk that the high-temperature soup will easily spill out of the pot body. Therefore, many food processors are designed with a pressing structure to press the cup cover onto the cup body during the structural design process. When the food processor is in use, the cup cover needs to be pressed against the cup body first to prevent the cup body from shaking and reduce the noise of the whole machine. At the same time, as long as the food processor is executing a certain cooking program, the pot cover is not allowed to separate from the pot body during the process. Therefore, how to achieve filling and juice collection in food processors with such a pot cover structure still needs further improvement. Summary of the invention

[0036] The upper cover 12 is roughly circular and movably arranged above the lower cover 11. The upper cover 12 is provided with an upper through hole 121, and the area of ​​the upper through hole 121 is greater than or equal to the area of ​​the feeding hole 112; the upper cover 12 is provided with a circle of circularly distributed tooth grooves 122, and the upper cover 12 is provided with an upper positioning magnet 123, see Figure 1 As shown; the installation positions of the lower positioning magnet 113 and the upper positioning magnet 123 satisfy: when the lower positioning magnet 113 and the upper positioning magnet 123 are attracted, the upper through hole 121 of the upper cover 12 is simultaneously away from the air hole 111 and the feeding hole 112 on the lower cover 11, and at this time, the upper through hole 121 is neither connected with the air hole 111 nor connected with the feeding hole 112, and at this time, the pot cover composed of the upper cover 12 and the lower cover 11 is in the initial state as a whole;

[0037] The gear plate 2 is roughly disc-shaped. A gear 21 that can mesh with the tooth groove 122 on the upper cover 12 is provided on half of the circumferential edge of the gear plate 2 in an arc distribution. The other half of the circumferential edge is not provided with a gear, but an arc contact surface 22. A trigger switch 6 is provided below the gear plate 2. Figure 3 As shown;

[0038] A driving motor 91 capable of driving the gear plate 2 to rotate, wherein the driving motor 91 is a reduction motor;

[0039] The mounting bracket 9 is used to mount the driving motor 91. The mounting bracket 9 is hollow inside. The driving motor 91 is mounted inside the mounting bracket 9. The upper surface of the mounting bracket 9 is provided with an initial position micro switch 3, a juice collection position micro switch 4 and a feeding position micro switch 5. Figure 4 shown.

[0040] The gear plate 2 can rotate under the drive of the driving motor 91. When the gear 21 on the gear plate 2 is meshed with the tooth groove 122 on the upper cover 12, the gear plate 2 can drive the upper cover 12 to rotate, so that the upper through hole 121 on the upper cover 12 can be opposite to the air hole 111 on the lower cover 11 and the two can be connected, or the upper through hole 121 on the upper cover 12 can be opposite to the feeding hole 112 on the lower cover 12 and the two can be connected, or the upper through hole 121 on the upper cover 12 can be away from the air hole 111 and the feeding hole 112 on the lower cover 11 at the same time, so that the upper through hole 121 is neither connected with the air hole 111 nor the feeding hole 112.

[0041] In this embodiment, the installation positions of the initial position micro switch 3, the juice collection position micro switch 4 and the feeding position micro switch 5 meet the following requirements:

[0042] When the trigger switch 6 contacts the initial position micro switch 3, the upper through hole 121 on the upper cover 12 is away from the air hole 111 and the feeding hole 112 on the lower cover 11. At this time, the upper through hole 121 is neither connected to the air hole 111 nor to the feeding hole 112. Figure 5 As shown; at this time, the arc contact surface 22 on the gear plate 2 is opposite to the upper cover 12 and remains disengaged. At this time, the pot cover composed of the upper cover 12 and the lower cover 11 is in the initial state as a whole;

[0043] When the trigger switch 6 contacts the juice collection position micro switch 4, the gear 21 on the gear plate 2 meshes with the tooth groove 122 on the upper cover 12, and the upper through hole 121 on the upper cover 12 is opposite to the air hole 111 on the lower cover 11. At this time, the upper through hole 121 is connected with the air hole 111 and is not connected with the feeding hole 112. Figure 6 As shown;

[0044] When the trigger switch 6 contacts the feeding position micro switch 5, the gear 21 on the gear plate 2 meshes with the tooth groove 122 on the upper cover 12, and the upper through hole 121 on the upper cover 12 is opposite to the feeding hole 112 on the lower cover 11. At this time, the upper through hole 121 is connected to the feeding hole 112 and is not connected to the vent hole 111. Figure 7 shown.

[0045] This embodiment also provides a food processor using the above-mentioned pot cover assembly. Figure 8 , 9 As shown, it includes a machine base 7, the machine base 7 includes a base 71 and a side wall 72 vertically arranged with the base 71, a pot body 8 with an opening at the top arranged on the base 71, an upper cover 12 and a lower cover 11 are combined together to cover the opening of the pot body 8, and a gear plate 2 and a driving motor 91 are arranged in the side wall 72 beside the pot body 8, and can be linked with the upper cover 12. A controller is arranged in the base 7, the driving motor 91 is electrically connected to the controller, and the initial position micro switch 3, the juice collection position micro switch 4 and the feeding position micro switch 5 are also electrically connected to the controller.

[0046] In the initial state, the lower positioning magnet 113 on the lower cover is attracted to the upper positioning magnet 123 on the upper cover, and the upper through hole 121 of the upper cover 12 is away from the air hole 111 and the feeding hole 112 on the lower cover 11. At this time, the upper through hole 121 is neither connected to the air hole 111 nor to the feeding hole 112. At the same time, the arc contact surface 22 on the gear plate 2 is opposite to the upper cover 12, and the pot cover as a whole remains disengaged from the gear plate in the base, and the cover body as a whole can be moved away. When it is needed, the pot cover as a whole is closed on the pot body opening. The controller stores a cooking execution program including a juice collecting stage and / or an ingredient adding stage during the cooking process. When the controller is executing the cooking execution program and reaches the juice collecting stage, the controller controls the drive motor 91 to start, so that the gear plate 2 starts to rotate. After the gear 21 on the gear plate 2 is meshed with the tooth groove 122 on the upper cover 12, the gear plate 2 drives the upper cover 12 to rotate. When the controller receives the juice collecting position microswitch 4, it controls the drive motor to stop rotating. At this time, the upper through hole 121 on the upper cover 12 is just opposite to the air hole 111 on the lower cover 11, and the upper through hole 121 is connected to the air hole 111, and the cooking continues. After the preset time, the controller drives the motor 91 to start and rotate in the opposite direction again, so that the pot cover returns to the initial position. When the controller receives the signal of the initial position micro switch 3, the controller controls the driving motor to stop rotating. At this time, the upper through hole 121 on the upper cover 12 is away from the air hole 111 and the feeding hole 112 on the lower cover 11 at the same time, and the upper through hole 121 is neither connected with the air hole 111 nor the feeding hole 112; if the food is added to the stage, the controller controls the driving motor 91 to start and rotate in the reverse direction, so that the pot cover returns to the initial position. When the controller receives the signal of the initial position micro switch 3, the driving motor stops rotating. Therefore, in the cooking execution stage, since the gear 21 on the gear plate 2 is engaged with the tooth groove 122 on the upper cover 12, the entire pot cover is fixed at the opening of the pot body, which not only plays the role of locking the pot cover, so that the pot body always remains in a safe state and reduces the operating noise, but also drives the upper cover to rotate, so that the pot cover presents different functional modes. When the cooking program is finished, the driving motor 91 drives the gear plate 2 to rotate to return the pot cover to the initial state.
