Description

Technical Field

[0001] This utility model relates to the field of cooking machine technology, and in particular to an automatic cooking machine. Background Technology

[0002] Adding ingredients to the pot is an essential step in cooking, and adding the right ingredients at the right time plays a crucial role in the quality of the dish. Generally, ingredients are added manually, meaning the amount and timing of each ingredient are determined by the cook. This method results in variations in the timing of additions when cooking the same dish in different batches, leading to differences in taste, and manual addition is also tedious. In recent years, with the development of automation technology, automated cooking machines have gradually come into view. However, the ingredient-adding mechanisms of currently developed automated cooking machines are generally not well-designed, mainly due to their complex structure, high cost, and large space occupation. These shortcomings are significant drawbacks in both home and commercial applications, especially in the cost- and size-sensitive consumer market, where existing cooking machines with ingredient-adding mechanisms have almost no market. However, automatic, time-based ingredient addition is crucial for ensuring the taste and automation of a cooking machine.

[0003] The inventor previously filed a patent application with application number CN202110904977.6, which disclosed an automatic cooking machine. This automatic cooking machine can automatically add ingredients and has a compact structure. However, its door is installed on a rotating output shaft, which is troublesome to disassemble and assemble. Before the food is taken out of the pot after cooking, the door needs to be lifted first, and the remaining uncooked ingredients on the door will slide into the pot.

[0004] The inventor previously filed an application with application number CN202411319303.X, which disclosed an automatic cooking machine. This automatic cooking machine can automatically add ingredients and has a compact structure. Its compartment door can be quickly installed at the bottom of the compartment body. The compartment door and the compartment body need to be pre-assembled together. Some users believe that the disassembly and assembly of the compartment door in this solution is not very convenient. Utility Model Content

[0005] The purpose of this invention is to provide an automatic cooking machine that not only allows for easy disassembly and assembly of the compartment door, but also avoids the defect of uncooked food residue on the compartment door sliding into the pot when the compartment door is lifted before the food is taken out of the pot.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An automatic cooking machine includes: a chamber body, a door, a drive assembly, a cooking container, and a frame; the drive assembly and the cooking container are directly or indirectly mounted on the frame; the chamber body includes at least two vertically connected storage compartments and a cavity, the storage compartments and the cavity being circumferentially distributed, the cavity extending from the outer edge of the chamber body to its central area, and the cavity being able to be fitted onto or separated from the drive assembly, thereby enabling quick assembly and disassembly of the chamber body; the door includes a solid area and a notch area, the solid area and the notch area being circumferentially distributed, the notch area extending from the outer edge of the door to its central area; during operation, the door is attached to the bottom of the chamber body; the center of the notch area of ​​the door is a slot, and the outer edge of the door is provided with a handle for easy assembly and disassembly; the output shaft of the drive assembly is located in the central area of ​​the chamber body, a transmission body is mounted on the output shaft, the slot of the door is engaged with the transmission body, and the transmission body drives the door to rotate through the slot.

[0008] The beneficial effects of the above technical solution are as follows: the compartment door can be quickly installed on the transmission body by pushing the handle backward, and the compartment door can be quickly disassembled by pulling the handle forward. The compartment door and the compartment body do not need to be pre-assembled together. The compartment door does not need to be lifted when disassembling and assembling, which avoids the defect that the uncooked food residue on the compartment door will slide into the pot when the compartment door is lifted.

[0036] The specific implementation of this utility model will be described in more detail below with reference to specific embodiments. Example 1

[0037] like Figures 1-4 This embodiment provides an automatic cooking machine, which includes: a housing 101, a door 102, a drive assembly 2, a frame 3, a cooking container 4, a heating device 5, an electronic control module 6, and a touch screen 7. The door 102 is located at the bottom of the housing 101. The housing 101 includes three vertically connected storage compartments 101a. The door 102 has a notch. When the notch of the door 102 is below a designated storage compartment 101a, the food in that compartment is released. The drive assembly 2 drives the door 102 to rotate to different angle positions at different times, thereby releasing the food from different storage compartments 101a at different times. The cooking container 4 has its opening facing upwards to receive the food released from the housing 101 at different times. Preferably, during operation, the housing 208 of the drive assembly 2 has a gap for vertical movement between the door 102 and the body 101, so that the drive assembly 2 does not limit the body 101 and the door 102 in the vertical direction, and the frame 3 does not limit the body 101 and the door 102 in the vertical direction. The door 102 presses against the opening of the cooking container 4, so that the body 101 presses against the door 102, thereby ensuring that the door 102 and the bottom surface of the body are tightly attached together, thereby preventing the cross-contamination of ingredients in different storage compartments 101a.

[0038] The drive assembly 2 is hinged to the frame 3. The heating device 5 is positioned and installed inside the frame 3. The cooking container 4 is placed on the heating device 5 and indirectly placed on the frame 3. The positioning bracket 302 is part of the frame 3 and can be detachably placed on top of the heating device 5 (for easy cleaning). Its downward claw 302a is engaged with the outer periphery of the heating device 5, and its upward claw 302b is engaged with the outer periphery of the cooking container 4, thereby positioning the cooking container 4 on the frame 3.

[0039] The electronic control module 6 is installed inside the frame 3, and the touch screen 7 is located at the front end of the frame 3. The user selects the dish to be cooked via the touch screen 7, which then transmits the information to the electronic control module 6. The electronic control module 6 controls the movement of the drive assembly 2 and the heating device 5. Furthermore, the automatic cooking machine also includes a stirring structure 8, which is also driven by the drive assembly 2 to rotate, thereby achieving the stirring and stir-frying of the ingredients. The heating device 5 is an electromagnetic heater, a resistance heater, or a natural gas heater, etc., preferably an electromagnetic heater.

[0040] Motor 204 drives bevel gear 203 to rotate. The upper end of output shaft 201 is a bevel gear that drives bevel gear 203. Transmission body 202 is mounted on output shaft 201. The center of door 102 is a slot 102c, which engages with transmission body 202, allowing transmission body 202 to drive door 102 to rotate. Thus, motor 204 can drive door 102 to rotate via transmission. Proximity switch 205 determines the origin of output shaft 201 by detecting a protruding structure on output shaft 201. The upper end of shaft 206 is connected to motor 207, and the lower end is connected to stirring structure 8, allowing motor 207 to drive stirring structure 8 to rotate. Preferably, motor 204 is a stepper motor, and motor 207 is a DC geared motor. Motors 204, 207, and related transmission structures are all housed within housing 208.

[0041] like Figure 5 The hopper body 101 is generally cylindrical and includes three vertically connected storage hoppers 101a and a cavity 101b. The three storage hoppers 101a and the cavity 101b are circumferentially distributed, with the three storage hoppers 101a evenly spaced at 90-degree intervals around the central axis of the hopper body 101. The cavity 101b extends from the outer ring of the hopper body 101 to the central region 101c. The outer ring of the cavity 101b has a retaining edge 101i. The cavity 101b is fitted onto the housing 208 of the drive assembly 2. The three side walls of the cavity 101 and the retaining edge 101i fit around the boss 208a on the upper part of the housing 208, thereby positioning the hopper body 101 horizontally. Furthermore, the bottom outer ring of the compartment 101 has an outer retaining ring 101d, which is annular and breaks at the cavity 101b. This retaining ring radially limits the compartment door 102, restricting its horizontal movement. Preferably, the compartment 101 is made of PP plastic and is mainly formed using injection molding.

[0042] like Figures 6-8The storage door 102 is roughly circular, comprising a solid area 102a and a notched area 102b, which are circumferentially distributed. The notched area 102b extends from the outer edge of the storage door 102 to the central area 102c. Excluding the central area 102c, the notched area 102b occupies approximately one-quarter of the storage door 102's sector. The central area 102c has a U-shaped slot structure. A handle 102d is hinged to the lower edge of the storage door 102; preferably, the handle 102d is located directly opposite the notched area 102b. A shoulder screw 102e hinges the solid area 102a and the handle 102d together. The soft rubber pad 102f between the solid area 102a and the handle 102d is compressed, creating damping at the hinge, allowing the handle 102d to be unfolded or folded on the storage door 102. Since the door 102 covers the cooking container 4 during operation, it needs to have heat insulation to prevent the food in the storage compartment 101a from being heated. Preferably, the door 102 has a cavity between its upper and lower surfaces, and the cavity is filled with vacuum or gas. Preferably, the door 102 is made entirely of glass.

[0043] like Figure 9 and 10 Before installing the compartment door 102, first lower the drive assembly 2. Then, the user holds the handle 102d and places the compartment door 102 on the upper opening of the cooking container 4. The user then pushes the compartment door 102 backward, causing the slots 102c to engage with the planes on both sides of the transmission body 202. This allows the transmission body 202 to rotate the compartment door 102. Furthermore, the lower outer ring of the compartment body 101 has a downward-extending retaining ring 101d, which fits around the outer ring of the compartment door 102 to prevent the compartment door 102 from disengaging from the transmission body 202 during rotation. Before cooking, install the compartment door 102 first, then install the compartment body 101, ensuring the retaining ring 101d fits around the outer ring of the compartment door 102. After cooking, remove the compartment body 101 first, then remove the compartment door 102. After the compartment door 102 is installed, the handle 102d can be manually folded, or the handle 102d can be automatically folded upon contact with the frame after the compartment door 102 is rotated. To disassemble the compartment door 102, unfold the handle 102d, hold the handle 102d and pull forward to remove the compartment door 102. After cooking, the compartment door 102 will be quite hot; using the handle 102d to disassemble the compartment door 102 will prevent burns. Example 2

[0044] like Figure 11 and 12 The difference between the automatic cooking machine provided in this embodiment and that in embodiment 1 is that the chamber 101 does not have a retaining ring 101d, the upper opening of the cooking container 4 has a retaining ring 401, the inner side below the retaining ring 401 is a support surface 402, the chamber door 102 presses on the support surface 402, and the retaining ring 401 is fitted around the outer ring of the chamber door 102. This can prevent the chamber door 102 from disengaging from the transmission body 202 when it rotates. Example 3

[0045] like Figures 13-15 The difference between the automatic cooking machine provided in this embodiment and that in Embodiment 1 is that the chamber 101 does not have a retaining ring 101d, and the transmission body 202 is equipped with ball bearings 202a on both sides. The door retaining groove 102c has a latching groove 102g on each side, which engages the ball bearings 202a on both sides, thus preventing the door 102 from disengaging from the transmission body 202 when rotating. A spring inside the ball bearing 202a pushes the ball outwards; when subjected to external force, the ball retracts inwards. This allows the ball to retract when the door 102 is installed, and extends outwards after the door 102 is in place. The ball bearing 202a can also be an elastic body of other structures.

[0046] This section provides specific details for all the above embodiments. In a cross-section perpendicular to the rotation axis of the compartment door, the outer contours of the compartment body and the compartment door are preferably circular (including a circle with a notch), but can also be polygonal or other shapes. The automatic cooking machine can be an automatic stir-fry machine, an automatic steamer, an automatic soy milk maker, or other similar cooking machines; in some specific applications, a stirring structure is not essential, nor is a heating device.

[0047] The above description is only a few preferred embodiments of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
