Description

Technical Field

[0001] This utility model relates to the flipping and positioning control of an intelligent cooking machine, and more particularly to a control device that causes the furnace core of the cooking machine to swing to a set position. Background Technology

[0002] In today's era of rapid technological development, cooking machines are becoming increasingly intelligent. In addition to automatic cooking, the wok can also be rotated to different angles to set positions, so that the wok opening faces different directions, thereby cooperating with other components in the cooking machine to complete multiple tasks such as feeding, washing the wok, and serving the food.

[0003] The existing method for determining the workstation is as follows: a photoelectric transceiver control board is installed in the position control device and a photoelectric transceiver unit corresponding to each workstation is set up. When the wok needs to be flipped to a certain workstation, the drive device drives the light shield to rotate to the position corresponding to the photoelectric transceiver unit of that workstation and forms a light path, thereby determining that the wok has arrived at that workstation.

[0004] The solution has the following drawbacks: the position control device and the drive device are installed on the left and right sides of the cooking machine frame, respectively, resulting in low space utilization of the cooking machine. Furthermore, when the workstation positioning is incorrect, both sides of the frame need to be disassembled to remove the position control device and drive device for inspection and maintenance, which is inefficient. In addition, the cooking process of the cooking machine is complex and involves many workstations. If all workstations are located by photoelectric sensors, the error tolerance is low, thereby increasing the maintenance cost of the entire position control device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a control device that is highly integrated, highly reliable, and easy to disassemble and assemble, so as to make the furnace core of the cooking machine swing to the set position.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A control device is provided to swing the furnace core of a cooking machine to a set position. The device includes a drive motor for rotating the shaft of the furnace core, a limiting component for determining the initial position of the furnace core, and a positioning component for rotating the shaft to the set position. The limiting component is located on a motor base on a side opposite to the furnace core, the drive motor is located on the side of the motor base, the output shaft of the drive motor is perpendicular to the shaft, and the positioning component is located inside the drive motor.

[0008] Preferably, the limiting component includes a photoelectric emitting plate, a photoelectric receiving plate, and a light-shielding plate disposed between the photoelectric emitting plate and the photoelectric receiving plate. Between the photoelectric emitting plate and the photoelectric receiving plate, there are three sets of photoelectric transceiver components for detecting that the rotating shaft is in the initial position, the forward rotation limit position, and the reverse rotation limit position. A light-transmitting hole is provided on the light-shielding plate, and the light emitted by the light emitting tube in the photoelectric transceiver component passes through the light-transmitting hole and is received by the corresponding light receiving tube.

[0009] Preferably, a housing for accommodating the limiting component is fixedly connected to the motor base on the same side as the limiting component, the photoelectric receiving plate is fixed to the inner side wall of the housing, the light shield is sleeved on the rotating shaft passing through the photoelectric receiving plate, and the photoelectric emitting plate is mounted on the photoelectric receiving plate via a male and female connector.

[0010] Preferably, the positioning component is a Hall sensor.

[0011] Preferably, the output shaft of the drive motor is connected to the rotating shaft via a worm gear structure.

[0012] Preferably, the worm wheel in the worm gear structure is placed inside the motor base and fixedly sleeved on the rotating shaft, and the output shaft of the drive motor is fixedly connected to the worm in the worm gear structure. The worm passes through the motor base and meshes with the worm wheel.

[0013] Preferably, a cover plate is fixed to the outer end face of the housing to seal the limiting component inside the housing. The cover plate is provided with a wire hole, which passes through the rotating shaft. The cover plate and the rotating shaft are connected together by a bearing.

[0014] Preferably, the rotating shaft is a bushing with an engagement structure at its inner end that can rotate coaxially with and connect to the support shaft of the furnace core.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the control device of this utility model is used to drive and control the furnace core (not shown in the figure) of the cooking machine to rotate forward or backward from a determined initial position using its rotating shaft 1 as the rotation axis. Figure 1 Taking the direction from left to right and rotating the rotating shaft 1 counterclockwise (i.e., clockwise) as an example, and taking the pot opening of the furnace core facing directly downward as the starting point of the furnace core's rotation, the angle of rotation starting from the starting point is determined by the rotation angle. The larger rotation angle is the rear, and the smaller rotation angle is the front (the same applies below). The furnace core is swung at a set angle so that it is positioned at a certain set position and completes the corresponding action with the assistance of other devices in the cooking machine.

[0022] The initial position is determined by the limiting component in the control device. When the rotating shaft 1 rotates from the initial position to the required set position, its rotation direction and angle are controlled by the positioning component in the control device. The control device of this utility model integrates the drive motor 2 for driving the furnace core to swing, the limiting component and the positioning component into one unit. The structure is compact and easy to disassemble and maintain.

[0023] This utility model preferably includes six setting stations, and the six setting stations (listed from front to back) and the actions to be performed when the furnace core is in each setting station are as follows:

[0024] Serving position: The wok in the stove is positioned with its opening facing down so that the cooked food can be poured onto a plate;

[0025] Observation position: The opening of the wok faces the machine door for easy observation by the user;

[0026] Feeding position: The wok receives the ingredients fed in by the feeding device;

[0027] Stir-fry position: The wok heats and stirs the ingredients inside, and the lid can be placed on the wok opening to assist in cooking.

[0028] Washing area: The cleaning device cleans the inner wall of the wok;

[0029] Pour out the water: Turn the wok upside down to pour out the cleaning water left in the wok.

[0030] The control device is a set, which is fixedly installed on the outer side of the cavity wall of the inner cavity of the cooking machine (not shown in the figure). The furnace core is set in the inner cavity. The rotating shaft 1 is a bushing with a hollow channel inside. The wires in the furnace core, such as the wires of the sensor that detects the temperature of the wok and the wires of the wok heating device, are led out from the hollow channel to the outside of the inner cavity and connected to the main control circuit. The outer end of the rotating shaft 1 (outer: refers to the direction away from the vertical axis of the inner cavity, inner / inner: refers to the direction towards the vertical axis, the same below) is connected to the drive motor 2. Its inner end passes through the cavity wall and is connected to the support shaft (not shown in the figure) fixed on the outer wall of the furnace core through the interlocking structure (the specific structure is described below). On the cavity wall on the other side of the inner cavity, there is a driven shaft coaxial with the rotating shaft 1. The inner end of the driven shaft passes through the cavity wall and is connected to another support shaft on the outer wall of the furnace core through the interlocking structure.

[0031] The control device includes the drive motor 2, the limiting component, and the positioning component disposed within the drive motor 2.

[0032] 1. Limiting components

[0033] The limiting component is used to determine the initial position of the furnace core swing, and then the positioning component controls the drive motor 2 to drive the rotating shaft 1 to rotate the furnace core from the initial position to the required set position in the determined rotation direction by a set angle.

[0034] The limiting component is located on the outside of the motor base 21 (the motor base 21 is used to install the drive motor 2), and includes a photoelectric emitting plate 3, a photoelectric receiving plate 32, and a light-shielding plate 31 disposed between the photoelectric emitting plate 3 and the photoelectric receiving plate 32.

[0035] To facilitate the installation of the limiting component, a housing 4 is fixed to the outside of the motor base 21, and the limiting component is housed in the cavity of the housing 4.

[0036] 1) Outer shell 4

[0037] The outer shell 4 is generally hollow cylindrical and has the cavity described above. It has a perforation on its inner side that communicates with the cavity, and its outer side is an open surface.

[0038] The outer shell 4 is fitted onto the rotating shaft 1 and the hole wall of the perforation is spaced apart from the rotating shaft 1. The inner end face of the outer shell 4 is sealed and fixed to the motor base 21, thereby connecting the limiting component and the drive motor 2 into one unit.

[0039] 2) Photoelectric emitting plate 3, photoelectric receiving plate 32 and light shielding plate 31

[0040] The photoelectric emitting plate 3, the light-shielding plate 31, and the photoelectric receiving plate 32 are arranged alternately from the outside to the inside, and each has a central hole.

[0041] The central hole on the photoelectric receiving plate 32 passes through the rotating shaft 1 and is fixed to the inner wall of the cavity, with a gap between the central hole and the rotating shaft 1. A mounting ring is provided on the rotating shaft 1, and a light-shielding plate 31 is fitted onto the outer wall of the rotating shaft 1 and locked and fixed to the mounting ring. The central hole on the photoelectric emitting plate 3 passes through the rotating shaft 1 and is quickly installed on the photoelectric receiving plate 32 via a male-female connector, with a gap between the central hole and the rotating shaft 1. Preferably, the photoelectric emitting plate 3 has three observation holes to facilitate observation of whether the male connector on the photoelectric emitting plate 3 is properly connected to the connector on the photoelectric receiving plate 32.

[0042] Preferably, each of the photoelectric emitting plate 3 and the photoelectric receiving plate 32 is provided with a notch connected to its central hole in the circumferential direction. This allows the photoelectric emitting plate 3 or the photoelectric receiving plate 32 to be pulled off the rotating shaft 1 through the notch without first removing the wires that pass through the hollow channel of the rotating shaft 1, thus improving the efficiency of disassembly and assembly.

[0043] Between the photoelectric emitting plate 3 and the photoelectric receiving plate 32, three sets of photoelectric transceiver components are respectively provided to detect the initial position, the forward rotation limit position, and the reverse rotation limit position of the rotating shaft 1. The initial position is preferably located between the feeding position and the cooking position. The forward rotation limit position is set before the food discharge position, and the reverse rotation limit position is set after the pot washing position. The forward rotation limit position and the reverse rotation limit position are set to prevent the rotating shaft 1 from rotating excessively, which could cause the wires led out from the furnace core to become tangled or even break.

[0044] Each set of optoelectronic transceiver components includes a light emitting tube and a light receiving tube. Correspondingly, a light-transmitting hole is provided on the light shield 31, and the light emitting point of all light emitting tubes, the light receiving point of all light receiving tubes and the light-transmitting hole are coaxially arranged to ensure that when the rotating shaft 1 carries the light shield 31 to the initial position, the forward rotation limit position or the reverse rotation limit position, the light emitted by the corresponding light emitting tube can pass through the light-transmitting hole and be received by the corresponding light receiving tube, thereby determining the position of the rotating shaft 1 at this time.

[0045] To seal the limiting component in the cavity of the housing 4, a cover plate 5 is sealed and fixed to the outer end face of the housing 4.

[0046] The installation method of cover plate 5 and outer shell 4 is as follows:

[0047] The outer contour of the cover plate 5 is shaped like a plum blossom and has several locking holes. Correspondingly, the outer edge of the outer shell 4 has the same number of studs as the locking holes. A wiring hole is provided in the center of the cover plate 5. This wiring hole is coaxial with the rotating shaft 1 and its diameter is slightly larger than the outer diameter of the rotating shaft 1. An inwardly extending annular positioning groove is also provided on the inner side of the cover plate 5. When installing the cover plate 5, its wiring hole passes through the rotating shaft 1, and the positioning groove fits and engages the outer edge of the outer shell 4. Then, the cover plate 5 is fixed to the outer shell 4 with bolts.

[0048] To seal the gap between the wiring hole and the rotating shaft 1, a first bearing 6 is provided therebetween, specifically:

[0049] A step is provided on the outer end of the rotating shaft 1 for positioning and installing the first bearing 6. Correspondingly, an inwardly extending annular protrusion is provided on the inner side of the cover plate 5, around the wiring hole. The first bearing 6 overlaps the step, and the inner ring of the first bearing 6 is sealed and fitted onto the rotating shaft 1. After the cover plate 5 is installed in place, the outer ring of the first bearing 6 is fitted and locked in the annular protrusion, and the outer end face of the outer ring abuts against the inner end face of the cover plate 5, thereby stably installing the first bearing 6 between the cover plate 5 and the rotating shaft 1 and sealing the gap. The step and the cover plate 5 restrict the axial displacement of the first bearing 6 as it rotates with the rotating shaft 1, while the protrusion restricts the radial displacement of the first bearing 6.

[0050] 2. Drive motor 2 and positioning assembly

[0051] The drive motor 2 is used to drive the rotating shaft 1 to rotate around its axis, and the rotating shaft 1 drives the support shaft to swing forward or backward around the axis.

[0052] The drive motor 2 is mounted on one side of the motor base 21, and its output shaft is connected to the rotating shaft 1 through a worm gear 22 and worm 23 structure, and the output shaft is perpendicular to the rotating shaft 1 in opposite planes.

[0053] 1) Motor base 21

[0054] The motor base 21 is a rectangular body and has an inwardly recessed cavity. This cavity is used to install the worm gear 22 and worm 23 structure. A through hole coaxial with the cavity and penetrating the motor base 21 is provided at the bottom of the cavity.

[0055] The motor base 21 passes through the rotating shaft 1 and is located between the outer shell 4 and the cavity wall of the inner cavity. Its through hole is coaxial with the rotating shaft 1 and a gap is left between them to allow the rotating shaft 1 to rotate freely. The motor base 21 is fixedly connected to the frame of the cooking machine. The motor base 21 connects the components including the outer shell 4, the rotating shaft 1, the worm gear 22 and worm 23 structure, and the drive motor 2 together and bears the load of the components.

[0056] In the worm gear 22 and worm 23 structure, the worm gear 22 is coaxially arranged with the rotating shaft 1. It is fixedly sleeved on the rotating shaft 1 and placed in the cavity, with the worm gear 22 spaced apart from the cavity. Preferably, an annular baffle is also provided on the rotating shaft 1 to position and limit the worm gear 22. The output shaft of the drive motor 2 is connected to the worm 23. The drive motor 2 is fixed to the front end face of the motor base 21. Its output shaft carries the worm 23 backward into the cavity, so that the worm 23 meshes with the worm gear 22. The worm 23 and the cavity wall are connected by a bearing.

[0057] To seal the gap between the through hole of the motor base 21 and the rotating shaft 1, a second bearing 7 is provided. The second bearing 7 is specifically installed as follows: an annular mounting groove extends inward from the inner edge of the through hole, and a positioning step is provided on the rotating shaft 1. The second bearing 7 is sleeved on the rotating shaft 1 and abuts against the positioning step. When the motor base 21 is installed on the rotating shaft 1, the mounting groove fixes the outer ring of the second bearing 7 in it, and the second bearing 7 simultaneously seals the gap between the edge of the mounting groove and the rotating shaft 1.

[0058] 2) The positioning component is a Hall sensor built into the drive motor 2, that is, the drive motor 2 is a Hall motor.

[0059] 3. Occlusal structure

[0060] The interlocking structure can be a pin-type connection structure or an irregular interlocking connection structure.

[0061] Preferably, the present invention is a non-circular interlocking connection structure, which includes a locking block and a locking groove. The locking block is two axially symmetrical and arc-shaped block structures extending inward from the inner end of the rotating shaft 1. The locking groove is provided on the inner peripheral wall of the support shaft and there are two of them. The locking block can be adapted to be inserted into the corresponding locking groove so that the rotating shaft 1 and the support shaft are interlocked together. A radially protruding limiting block is provided on the inner peripheral wall of the support shaft and between the edges of the two locking grooves. The limiting block is used to limit the relative rotational movement between the rotating shaft 1 and the support shaft.

[0062] The pin-type connection structure includes a pin and a pin hole. A pin hole is provided on both the rotating shaft 1 and the support shaft. When the rotating shaft 1 is inserted into the hollow channel of the support shaft, the two pin holes are connected to each other. Then, the pin is inserted into the two pin holes to connect the rotating shaft 1 and the support shaft together.
