Description

Technical Field

[0001] The invention relates to a cooking machine capable of automatically adding materials. Background Art

[0002] Most of the cooking machines currently sold on the market do not have an automatic feeding mechanism. Those without an automatic feeding mechanism are only semi-automatic, requiring users to add ingredients during the cooking process, which complicates the cooking process. There are also a few models on the market that can achieve automatic feeding, but their implementation schemes are complex in structure, large in size, expensive, and difficult to clean. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a cooking machine which has a simple structure, is convenient to implement and can automatically add ingredients, with respect to the above-mentioned prior art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: a cooking machine capable of automatic feeding, comprising a machine body with an accommodating cavity formed therein, the machine body being provided with an opening communicating with the accommodating cavity, a pot body assembly capable of entering and exiting the accommodating cavity from the opening, the pot body assembly comprising a pot body with an opening at the top, and a pot cover arranged at the opening of the cover body, a stirring assembly being arranged in the pot body, and an automatic feeding mechanism being arranged above the pot body opening, characterized in that: the automatic feeding mechanism comprises a tray connected to the inner side of the pot cover, the tray and the upper inner area of ​​the pot cover forming a feeding bin, the tray being provided with two symmetrically arranged connecting ends, the two connecting ends being fixed to the inner wall of the pot cover by a fixed shaft, and the tray being able to rotate around the fixed shaft. ; A latch is provided at the bottom of the tray; a first limiting protrusion and a second limiting protrusion are also provided on the inner side of the pot cover, which are arranged at intervals up and down to prevent the tray from rotating; the tray has a first state for holding materials and a second state for releasing materials toward the pot opening; when the tray is in the first state, the upper side of the tray is limited below the first limiting protrusion, and the latch at the bottom of the tray exceeds the edge of the tray bottom plate and is limited above the second limiting protrusion, so that the tray is limited between the first limiting protrusion and the second limiting protrusion; after the latch is disengaged from the second limiting protrusion under the action of external force, the tray rotates around the fixed axis, and after the tray is flipped over, the materials on the tray slide toward the pot opening, thereby switching the tray from the first state to the second state.

[0005] As an improvement, the latch is connected with a paddle, and a return spring acting on the paddle of the latch is provided at the bottom of the tray, and the return spring always has a restoring force to move the latch toward the edge of the tray bottom plate.

[0006] As a further improvement, a driving mechanism and a first driving connection end connected to the driving mechanism are provided in the body at the rear side of the accommodating cavity, and a second driving connection end connected to the stirring assembly is provided on the rear side wall of the pot body assembly, and the second driving connection end can cooperate with and be transmission-connected to the first driving connection end. When the pot body assembly enters the accommodating cavity and the second driving connection end is transmission-connected to the first driving connection end, the stirring assembly can rotate in the pot body assembly under the drive of the driving mechanism through the power transmission cooperation between the first driving connection end and the second driving connection end.

[0007] As a further improvement, the stirring assembly is U-shaped, one end of the U-shaped stirring assembly is fixedly connected to the second driving connection end, and the other end of the U-shaped stirring assembly is rotatably connected to the front side of the pot body assembly.

[0008] As a further improvement, the distance from the lowermost end of the paddle on the latch to the rotation axis of the U-shaped stirring assembly is smaller than the rotation radius of the U-shaped stirring assembly; therefore, when the U-shaped stirring assembly is flipped to the inside of the pot cover under the drive of the driving mechanism, the U-shaped stirring assembly can drive the paddle on the latch at the bottom of the tray, thereby causing the latch to disengage from the second limiting protrusion. At this time, the tray rotates around the fixed axis, the tray flips, and the material on the tray slides toward the opening of the pot body, thereby switching the tray from the first state to the second state.

[0009] In order to detect whether the pot body assembly is installed in place and to control the flipping angle of the U-shaped stirring assembly, a first magnet is provided in the second drive connection end, and a first Hall sensor is provided at a clockwise angle α to the vertical direction and a second Hall sensor is provided at a counterclockwise angle β to the vertical direction on the rear side of the accommodating cavity. The setting position of the first Hall sensor and / or the second Hall sensor satisfies that: when the pot body assembly enters the accommodating cavity and the second drive connection end is transmission-connected to the first drive connection end, the first Hall sensor and / or the second Hall sensor can sense the first magnet on the second drive connection end and output a detection signal.

[0010] In order to facilitate the first Hall sensor and / or the second Hall sensor to detect the number of rotations of the stirring assembly, the center axis of the N and S poles of the first magnet in the second drive connection end is perpendicular to the rotation axis of the second drive connection end.

[0011] Further improvement, the first Hall sensor and the second Hall sensor are electrically connected to the control circuit board arranged in the machine body; at the same time, the driving mechanism is also electrically connected to the control circuit board; when no material needs to be added during the cooking process of the cooking machine, the control circuit board controls the driving mechanism to work so that the U-shaped stirring assembly flips back and forth in the pot body, that is, the control circuit board first controls the driving mechanism to work so that the U-shaped stirring assembly rotates clockwise to the N pole or S pole of the first magnet to reach the angle α, at which time the signal output by the first Hall sensor reaches an extreme value, and then the control circuit board controls the driving mechanism to work in the opposite direction so that the U-shaped stirring assembly rotates counterclockwise to the N pole or S pole of the first magnet to reach the angle β, at which time the signal output by the second Hall sensor reaches an extreme value, and then, the control circuit board controls the driving mechanism to work so that the U-shaped stirring assembly rotates clockwise to the N pole or S pole of the first magnet to reach the angle α, thereby repeatedly changing the rotation direction of the U-shaped stirring assembly to realize the continuous flipping of the food; the number of times the signal of the first Hall sensor or the second Hall sensor of the control circuit board reaches the extreme value is used to judge the number of rotations of the U-shaped stirring assembly.
